Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-5 This utility model provides a technical solution: a battery anti-foolproof frame for an electric motorcycle, including a body 1, a frame 2 fixedly installed inside the body 1, and a battery 6 placed in the mounting part of the frame 2. The top of the frame 2 is fixedly provided with a plurality of anti-foolproof components 3 for limiting the mounting position of the battery 6. The outer wall of the battery 6 is provided with a battery shell. One side of the battery shell is provided with a second groove 61 and a second protrusion 62 is fixedly provided on the opposite side. The foolproof component 3 includes a plurality of limit brackets 31 fixedly mounted on the frame 2, a first groove 33 formed on one side of the limit bracket 31 and inserted into the second protrusion 62, and a first protrusion 32 fixedly mounted on the other side of the limit bracket 31 and inserted into the second groove 61. A connecting frame 4 is vertically fixed in the middle of multiple limiting frames 31. Multiple fixing components 5 are fixed on the connecting frame 4, which are parallel to the limiting frames 31 and used to fix the battery 6. The fixing components 5 include a fixing plate 51 fixed on the connecting frame 4, and an elastic steel plate 52 fixed at the bottom of the fixing plate 51 in contact with the battery shell. By using the foolproof component 3 installed on the frame 2, incorrect installation of multiple batteries 6 is prevented. The first protrusion 32 and the first groove 33 are respectively provided on both sides of the limit bracket 31. When installing the battery 6, the battery must be inserted into the mounting cavity from the top of the frame 2. When the battery 6 is installed in the correct direction, the second protrusion 62 on one side of the battery shell is inserted and passes through the first groove 33, and the first protrusion 32 is inserted and passes through the second groove 61. If the battery 6 is installed in the wrong direction, the battery cannot be installed into the frame 2, thus preventing malfunctions and irreparable damage caused by incorrect installation of the battery 6.

[0019] More preferably, the frame 2 has multiple horizontally distributed first adjustment holes 21 on both sides, and the limiting frame 31 has openings at both ends that are opposite to the first adjustment holes 21. The limiting frame 31 is fixed to the frame 2 by screws. The first adjustment holes 21 on both sides of the frame 2 are threaded holes, and the limit frame 31 can be fixed on the frame 2 by screws. Multiple first adjustment holes 21 are distributed in sequence to install batteries 6 of different sizes and adjust the installation position distance.

[0020] More preferably, the outer wall of the connecting frame 4 is provided with a plurality of second adjustment holes 41 arranged in parallel in sequence, and the middle part of the outer wall of the limiting frame 31 is provided with an opening. The connecting frame 4 is fixed to the limiting frame 31 by bolts and matching nuts. The multiple second adjustment holes 41 on the outer wall of the connecting frame 4 facilitate the fixing of the connecting frame 4 onto the limiting frame 31 when the installation distance of the limiting frame 31 is changed.

[0021] A further preferred embodiment has an installation hole in the middle of the outer wall of the fixing plate 51, and is fixed to the outer wall of the connecting frame 4 by bolts and nuts; The mounting plate 51 is fixed to the outer wall of the connecting frame 4 by means of mounting holes opened on the outer wall of the fixing plate 51 and bolts and nuts. The mounting position of the fixing plate 51 can also be changed by means of the second adjustment hole 41.

[0022] In a further preferred embodiment, the fixing plate 51 is T-shaped with gaps between its two sides and the battery casing, and the elastic steel plate 52 is arc-shaped with its protruding parts in close contact with the battery casing.

[0023] More preferably, both ends of the elastic steel plate 52 are fixed to the fixed plate 51 by bolts and nuts respectively; The elastic steel plate 52 is fixed at both ends by bolts and nuts, which facilitates the assembly and disassembly of the elastic steel plate 52.

[0024] One specific application of this embodiment is as follows: When installing the battery 6, the spacing between the two limiting brackets 31 is pre-adjusted according to the size of the battery 6 model. When replacing or assembling the battery 6 into the frame 2, the correct orientation of the installation can be completed simply by aligning the second protrusion 62 on the outer wall of the battery casing with the first groove 33 opened in the limiting bracket 31. This prevents the battery 6 from being installed in the wrong orientation when it is arranged. After the battery 6 is installed, the fixing plate 51 is fixed to both ends of the connecting bracket 4 with bolts and is located on top of the battery 6 (where the bottom of the bolts is hidden under the fixing plate 51 and will not contact the battery). The elastic steel plate 52 provided at the bottom of the fixing plate 51 is tightly pressed against the top of the battery 6, constraining and fixing the battery 6 in the frame 2. The elastic buffer of the elastic steel plate 52 protects the battery 6.
