Commonly used for electric and human bicycle assembly frame

This creation is about a frame that is commonly used for electric and human bicycle assembly. This is especially a bicycle frame that can be used in the frame structure of electric or human bicycle assembly, thereby simplifying the process and effectively reducing the inventory. Convenience of universal interchange.

The figure shown in the first figure is a conventional bicycle frame 9, which is composed of an upper tube 91, a lower tube 92, a tube 93, two rear upper forks 94 and a lower lower fork 95, wherein A five-way socket 96 is provided at the intersection of the lower tube 92 and the lower and lower forks 95. The five-way socket 96 is provided with a spindle toothed disk set (the spindle toothed disk set is a conventional structure, in the figure) Not disclosed), this is the basic structure of a traditional human-type bicycle, but with the advancement of the times technology, in order to reduce the physical burden of the rider, there is a derivative of an electric bicycle, which is mainly a The tubular motor is coupled with the spindle sprocket set, and the electric drive tubular motor is used to drive the spindle sprocket set. The related patent case, such as EP1878650B1, is because the tubular motor part is not the patent feature of the present case, so it is not mentioned again, but For the frame manufacturer, the problem lies in the fact that the manual and electric five-way socket 96 are different in size and cannot be mutually versatile, resulting in the manufacturer facing the same frame 9 body, and must also be different. Demand for use (electric or manual) Welded pipe through five different seat 96, so will not only increase the burden and inconvenience of the inventory process significant increase, the joint distribution of the bike shop must also be limited store space, double face The above arrangement is troubled, which in turn affects the willingness to sell.

In view of this, after many times of research and improvement, the creator of this case finally completed the creation of the frame for electric and human bicycle assembly. The purpose of this creation is to provide a vehicle that can be used for electric and human bicycle assembly. Racks, to simplify the process and effectively reduce inventory, and the convenience of universal interchange.

In order to achieve the above purpose, the frame system of the frame is composed of an upper pipe, a lower pipe, a pipe, a second rear fork and a second rear fork, and the junction of the lower pipe, the seat pipe and the lower fork The welding seat has a fixing seat, and the fixing seat is locked with a different size of the five-way pipe socket according to the use requirement, wherein: the fixing seat has a top outer surface for connecting the pipe fittings of the frame body, and the outer surface is provided with a The inner hole has a plurality of first locking holes near the circumference of the inner hole, and the inner portion of the fixing seat is provided with an accommodating space for the five-way pipe socket to be combined; the five-way pipe socket, The utility model is provided with a spindle toothed disk set set, wherein an upper pipe flange is sleeved in the inner hole of the top of the seat body, and one side pipe flange is arranged on each side of the seat body, the side pipe convex The edge has a through hole, and the upper pipe flange is provided with an upper through hole, and a plurality of second locking holes are disposed near the periphery of the upper pipe flange, and the second locking hole is The first locking hole of the fixing seat corresponds to the corresponding number of first locking bolts, thereby consolidating the five-way socket and the fixing seat.

Please refer to the second, third and fourth figures. The purpose of this creation is for electric and manual use. The frame A of the vehicle assembly is composed of an upper tube 11, a lower tube 12, a tube 13, a second rear fork 14, and two lower forks 15, and the lower tube 12 and the seat A fixing seat 2 is welded to the intersection of the tube 13 and the lower and lower forks 15. The fixing base 2 is locked with a different size of the five-way socket 3 according to the requirements of use, wherein the fixing seat 2 has a top outer surface 20 for The tubular members of the frame body 1 are connected to each other (the respective tubular members include at least the upper tube 11, the lower tube 12, and the seat tube 13). The outer surface 20 is provided with an inner hole 200 and is disposed near the circumference of the inner hole 200. There is a plurality of first locking holes 201, 202, 203, and an accommodating space 21 is defined in the interior of the fixing base 2 for arranging the upper half of the five-way socket 3, and the front of the fixing base 2 The front side wall 210 has a first concave curved surface 214, and the two sides of the fixing base 2 are recessed with one side recess 211, and the rear side of the fixing base 2 is provided with a rear concave surface. The first rear convex portion 213 is adjacent to the first rear convex portion 213, and the first rear convex portion 213 has a first side hole 215. two a concave arc surface 216; the five-way socket 3 is provided for a spindle gear set B set (as shown in the fifth and seventh figures), and the top of the base 30 is provided with an upper through-tube flange 31 In the inner hole 200, the upper through-tube flange 31 is provided with an upper through hole 32, and a plurality of protruding portions 34, 35, 36 are provided near the periphery of the upper through-tube flange 31, and the protruding portion is provided. Each of the 34, 35, and 36 is provided with a second locking hole 341, 351, 361, and the second locking hole 341, 351, 361 corresponds to the first locking hole 201, 202, 203 of the fixing base 2, The first locking bolts 41, 42, 43 are locked for the corresponding number, thereby making the five-way socket 3 and the fixing base 2 A side pipe flange 33 is disposed on each side of the seat body 30. The side pipe flange 33 has a side through hole 331. The side through hole 331 is provided with an internal thread 332. The seat body 30 is provided. A second rear protrusion 37 is disposed on the rear side, and a second side hole 371 is defined in the second rear protrusion portion 37. The second rear protrusion portion 37 is nested in the rear recess 212 of the fixing base 2 . The second side hole 371 is corresponding to the first side hole 215 for a second locking bolt 44 to pass through, and is locked and fixed with a nut 45.

Through the combination of the above components, the user can select different combinations of the five-way socket 3 and the fixed seat 2 according to the combination requirements, and the upper through-tube flange 31 of the five-way socket 3 is sleeved on the fixed seat when combined. In the inner hole 200 of the second hole, each of the protruding portions 34, 35, 36 abuts against the first concave curved surface 214 and the second concave curved surface 216, respectively, the first locking holes 201, 202, 203 and the first The two locking holes 341, 351, 361 correspond to each other for the first locking bolts 41, 42, 43 to be locked and fixed, and the first side holes 215 correspond to the second side holes 371 for the The second locking bolt 44 passes through and is locked and fixed with the nut 45, and completes the locking combination of the five-way socket 3 and the fixing base 2.

The fifth, sixth and seventh figures are an embodiment of a five-way socket 3 for a human-type bicycle, and the five-way socket 3 can provide an assembly sleeve of a spindle toothed disk set B; The embodiment shown is an embodiment of a five-way socket 3 for an electric bicycle, wherein a tubular motor M is fitted in the lower tube 12, and the tubular motor M and an assembly sleeve are sleeved on the five-way socket 3 The spindle gear set B' power coupling (this part is not the technical feature of this case, and is a conventional technology, so it is not disclosed), and in the lower tube 1 A battery holder 50 is soldered to a battery 5 for providing power required by the tube motor M.

In summary, the creation can provide the user with the assembly requirements of the electric or human bicycle, and select the five-way socket of different specifications and the fixed seat lock combination on the frame, and the assembly is convenient and the process is simplified. And those who reduce the progress of inventory.
