DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Reference Figure 1 , Figure 2 The present embodiment provides a guard plate fixing structure, including a front support tube 1, a rear support tube 2, an upper connecting frame 3, a lower connecting frame 4, two footrest fixing plates 5 and two guard plates 6.

[0027] The upper connecting frame 3 includes a left side member 21, a right side member 22 and a pedal fixing plate 23. The front ends of the left side member 21 and the right side member 22 are connected to the front support tube 1, and the rear ends of the left side member 21 and the right side member 22 are connected to the rear support tube 2. The left and right ends of the pedal fixing plate 23 are respectively connected to the left side member 21 and the right side member 22. The front and rear ends of the lower connecting frame 4 are respectively connected to the front support tube 1 and the rear support tube 2. Two footrest fixing plates 5 are respectively fixed to the left side member 21 and the right side member 22.

[0028] The rear side portion of the guard plate 6 is mounted on the pedal fixing plate 23 through fasteners, and the front side portion of the guard plate 6 is mounted on the footrest fixing plate 5 through fasteners.

[0029] The working principle of the guard plate fixing structure of this embodiment is as follows:

[0030] This embodiment uses the footrest fixing piece 5 and the pedal fixing piece 23 usually provided on the frame of the electric bicycle as the installation base to realize the installation and fixing of the guard plate 6. Since the guard plate fixing piece is not required, the number of parts is reduced, the welding process of the guard plate fixing piece is omitted, and the production cost is reduced.

[0031] As a possible example, in this embodiment, the guard plate fixing structure also includes a water baffle 7, the left end of the water baffle 7 is connected to the guard plate 6 on the left side by a buckle, the right end of the water baffle 7 is connected to the guard plate 6 on the right side by a buckle, and the rear part of the water baffle 7 is plug-connected to the front support tube 1. By adopting the above structure to install the water baffle 7, there is no need to use a water baffle fixing plate, thereby reducing the number of parts and components, omitting the welding process of the water baffle fixing plate, and further reducing the production cost. In addition, since the welding process of the guard plate fixing plate and the water baffle fixing plate is omitted, the deformation of the frame caused by excessive welding can also be avoided.

[0032] As a possible example, in this embodiment, a plug is provided on the rear surface of the water baffle 7, and a socket is provided on the front support tube 1, and the plug is plugged and matched with the socket to realize the plug-in connection between the water baffle 7 and the front support tube 1. Compared with the construction process of welding the water baffle fixing plate on the front support tube 1, it is simpler and more convenient to provide the socket on the front support tube 1, and the cost is lower.

[0033] As a possible example, in this embodiment, there are two pedal fixing plates 23, which are respectively located at the front and rear of the upper connecting frame 3, and the guard plate 6 is connected to the pedal fixing plate 23 located at the rear side by fasteners. The pedal fixing plate 23 located at the front side fixes the front end of the pedal (the pedal is not shown in the drawings) by fasteners, and the pedal fixing plate 23 located at the rear side fixes the rear end of the pedal by fasteners. In this embodiment, the pedal fixing plate 23 and the footrest fixing plate 5 can be fixed by welding.

[0034] As a possible example, in this embodiment, a hook-shaped structure 61 bent forward is provided at the rear of the guard plate 6, and the hook-shaped structure 61 is connected to the pedal fixing plate 23 by a fastener to achieve the connection between the guard plate 6 and the pedal fixing plate 23. The hook-shaped structure 61 is located at the rear side of the pedal fixing plate 23, rather than the left or right side, so as to avoid collision with the left or right side wall of the packaging box during transportation.

[0035] As a possible example, in this embodiment, the footrest fixing plate 5 is provided with a guard plate mounting hole 51 (the footrest is not shown in the attached figure) and a footrest mounting hole 52, and the footrest mounting holes 52 are multiple and are respectively located at the front and rear sides of the guard plate mounting hole 51. By using multiple footrest mounting holes 52, the fixing effect of the guard plate 6 is improved. In this embodiment, the footrest fixing plate 5 is provided with one guard plate mounting hole 51 and two footrest mounting holes 52, and those skilled in the art may also select other numbers of guard plate mounting holes 51 and footrest mounting holes 52.

[0036] As a possible example, in this embodiment, the fastener is a screw. According to different actual needs, those skilled in the art may also select other types of fasteners.

[0037] This embodiment also provides an electric bicycle, including the above-mentioned guard plate fixing structure. Since the electric bicycle includes the above-mentioned guard plate fixing structure, it also has the above-mentioned advantages of the guard plate fixing structure, which will not be described in detail here.

[0038] The present invention uses specific examples to illustrate the principle and implementation of the present invention. The above examples are only used to help understand the method and core idea of ​​the present invention. At the same time, for those skilled in the art, according to the idea of ​​the present invention, there will be changes in the specific implementation and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
