[0001] The utility model relates to the technical field of electric two-wheel vehicles, in particular to a rear armrest for an electric two-wheel vehicle with a backrest adapter bracket. Background Technique
[0002] Most of the electric two-wheel vehicles on the market at present have the function of carrying people. In order to improve the safety of the rear passengers, a rear armrest and a backrest are usually fixedly arranged at the rear seat of the electric two-wheel vehicle. Electric two-wheel vehicles include electric bicycles, electric light motorcycles and electric motorcycles. According to relevant regulations, electric light motorcycles among them are not allowed to install rear armrests with backrest brackets, while electric bicycles and electric motorcycles are allowed to install rear armrests with backrest brackets, and the rear armrests with backrest brackets are all of an integrated structure. In this way, it is necessary to design two different rear armrest structures to adapt to different vehicle models, which invisibly increases the production cost of the enterprise.

The backrest adapter bracket includes a backrest connection part at the upper end for connecting the backrest and a rear armrest connection part at the lower end. A rotation stopping block is arranged on the rear armrest connection part, and a rotation stopping hole matched with the rotation stopping block is arranged on the rear armrest body. When the backrest adapter bracket is connected to the rear armrest body, the rotation stopping block is inserted into the rotation stopping hole. The upper and lower ends of the locking block are respectively connected to the rear armrest connection part, and the rear armrest body is clamped between the rear armrest connection part and the locking block.
[0006] Further, the locking block includes a locking block body, a seven-character hook arranged at the upper end of the locking block body, and a first connecting piece arranged at the lower end of the locking block body. The rear armrest connection part includes a rear armrest connection part body, a limiting hole arranged at the upper end of the rear armrest connection part body, and a second connecting piece arranged at the lower end of the rear armrest connection part body. The rotation stopping block is arranged between the second connecting piece and the rear armrest connection part body. The seven-character hook is inserted into the limiting hole, and the first connecting piece and the second connecting piece are fixedly connected.
[0007] Further, the first connecting piece and the second connecting piece are respectively provided with a first connecting hole and a second connecting hole, and the first connecting piece and the second connecting piece are connected to each other by bolts passing through the first connecting hole and the second connecting hole.
[0008] Further, at least two of the bolts are provided.
[0009] Further, a 2.5 mm gap is reserved between the first connecting member and the second connecting member, and an interference press fit is adopted between the rear armrest connecting portion body and the locking block body.
[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0011] 1. By designing a rear armrest structure for an electric two-wheeler with a backrest adapter bracket, the present utility model improves the versatility of the traditional rear armrest of an electric two-wheeler, can quickly and freely install a backrest as needed, unifies the design of the rear armrest, and enables flexible switching when selected for different vehicle models.
[0012] 2. The backrest adapter bracket is installed by clamping, and the fixing method of using a seven-character hook plus a connecting bolt is adopted.
