Description

Technical Field

[0001] The utility model relates to the technical field of electric bicycle processing, in particular to an electric bicycle front footrest mounting plate and an electric bicycle frame. Background Art

[0002] Electric bicycles have a certain range and are easy to drive, so they are widely used as short-distance commuting tools. In order to improve the driving comfort of electric bicycles, some electric bicycles are equipped with a front footrest for the driver to put his feet during driving. The front footrest is generally fixed to the corresponding mounting plate on the frame by bolts. In order to ensure the aesthetics of the electric bicycle, the mounting plate for the front footrest is generally located inside the plastic decorative part, and only two through holes are opened on the plastic decorative part so that the bolts can pass through the plastic decorative part and connect with the mounting plate. There is a certain distance between the existing plastic decorative parts and the mounting plate. If bolts are directly used to fix the front footrest and the mounting plate, the plastic decorative parts will be squeezed and deformed, thereby affecting the aesthetics of the electric bicycle. In the prior art, a nut is usually welded on the mounting plate to eliminate the distance between the plastic decorative parts and the mounting plate. In this way, when the front footrest is installed, the nut plays a positioning role, so that the front footrest will not squeeze the plastic decorative parts, thereby ensuring the original shape of the plastic decorative parts. However, by welding the nut on the mounting plate, the processing process of the electric bicycle frame is increased, which is not conducive to improving its processing efficiency. At the same time, it is not conducive to simplifying the structure of the electric bicycle frame. Utility Model Content

[0016] The following will be combined with specific embodiments and attached Figure 1-4, the technical solutions in the embodiments of the utility model are clearly and completely described. Obviously, the described embodiments are only part of the preferred embodiments of the utility model, not all of the embodiments. Those skilled in the art can make similar modifications without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0017] The utility model provides a front footrest mounting plate for an electric bicycle (such as Figure 1 As shown), it includes a mounting plate body 1, and two raised support parts 2 are arranged on the front side wall of the mounting plate body 1. The mounting plate body 1 and the two raised support parts 2 are an integral stamping part. In the actual processing process, the sheet metal part uses a stamping process to directly realize the processing and manufacturing of the mounting body 1. The thickness of the sheet metal part can be designed according to actual needs. A threaded hole 21 is arranged on the raised support part 2. After the mounting plate body 1 is stamped, a tapping drill bit is used to realize the processing of the threaded hole 21.

[0018] In practical applications, since the sheet metal is relatively thin, if the threaded hole 21 is directly used to connect with the bolt, it is easy to be disengaged. In order to increase the thread length of the threaded hole 21, two threaded tubes 3 corresponding to the two threaded holes are provided on the rear side wall of the mounting plate body 1, and the threaded tube 3 and the mounting plate body 1 are integral stamping parts. Specifically, after the protruding support part 2 is stamped by a punching machine, the sheet metal is turned over, and then the punching tool is replaced to punch and stretch the protruding support part 2, thereby realizing the processing of the smooth tube on the rear side of the protruding support part 2. After the smooth tube is processed, it is tapped by a tapping head, thereby realizing the processing of the threaded hole 21 and the threaded tube 3.

[0019] In order to reduce the weight of the mounting plate body 1, a weight-reducing hole 11 is provided between the two raised support portions 2. Furthermore, in order to improve the overall structural strength of the sheet metal of the mounting plate body 1, a backward-bent folded edge 12 is provided at the upper and lower portions of the mounting plate body 1, respectively.

[0020] The utility model also provides an electric bicycle frame, including the above-mentioned electric bicycle front footrest mounting plate, the electric bicycle frame includes two bottom edge tubes 4 relatively distributed front and back, the left end of the bottom edge tube 4 is bent upward, in order to facilitate welding and fixing the mounting plate body 1 at the left end bending inner corner of the bottom edge tube 4, here, the right end of the mounting plate body 1 is bent downward, and a mounting plate body 1 is fixedly arranged at the left end bending inner corner of each of the bottom edge tubes 4, the two bottom edge tubes 4 are distributed front and back symmetrically, and the raised support portion 2 faces the outside of the electric bicycle frame, a plastic decorative frame 5 is clamped and fixed on the electric bicycle frame, and a through hole 51 corresponding to the raised support portion 2 is arranged on the plastic decorative frame 5, and the raised support portion 2 is sleeved in the through hole 51. In actual application, after the plastic decorative frame 5 is installed, the bolts are passed through the mounting holes of the front footrests and then tightened on the corresponding raised support parts 2, thereby fixing the front footrests on the mounting plate. The supporting and limiting function of the raised support parts 2 can effectively prevent the front footrests from exerting an extrusion effect on the plastic decorative frame 5.

[0021] In the present utility model, "front", "back", "up", "down", "left" and "right" are relative positions used to conveniently describe positional relationships, and therefore cannot be understood as absolute positions to limit the scope of protection.

[0022] Except for the technical features described in the specification, all other technical features are known technologies to those skilled in the art.

[0023] The above description in combination with the accompanying drawings has detailed the preferred implementation modes and embodiments of the utility model, but the utility model is not limited to the above implementation modes and embodiments. For ordinary technicians in this technical field, several improvements and modifications can be made without departing from the concept of the utility model, and these improvements and modifications should also be regarded as the protection scope of the utility model.
