[0002] In the prior art, the utility model patent with the authorization announcement number "CN220430382U" discloses an electric motorcycle, which has a detachable battery pack installed in the frame, and the seat can be opened quickly to facilitate the removal and installation of the battery pack. However, there are the following problems: For this type of electric motorcycle without a pedal structure, only one battery can be installed at most, which will inevitably cause the problem of battery life anxiety. If two or more batteries are used, they usually need to be placed side by side in the area below the seat. For safety and battery life considerations, the applicant believes that it is best to use two batteries, such as Figure 1 As shown, placing batteries side by side horizontally will increase the width of the vehicle. Figure 2 As shown, longitudinal side-by-side arrangement increases the wheelbase of the vehicle. Therefore, no matter which method is used, a larger space below the pedal will be occupied, and it will inevitably lead to a decrease in the cornering performance of the vehicle. Based on this, the present application provides a multi-form replaceable battery structure for an electric motorcycle. Utility Model Content

[0022] 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.

[0023] Example

[0024] This embodiment provides Figure 3 and 4 The multi-form battery-replaceable structure of an electric motorcycle shown in the figure comprises a frame 1, the middle part of the frame 1 has a storage compartment for placing a battery pack 2, and only two battery packs 2 are arranged in the storage compartment. If more battery packs 2 are used, although the vehicle's endurance will increase, the wheelbase and risk will also increase. Therefore, the applicant believes that it is best to use two batteries, such as Figure 3 As shown, the battery pack 2 located at the top, i.e., close to the front of the vehicle, is arranged vertically, and the other battery pack 2 is placed horizontally. Figure 3 The upper part forms an inverted T-shaped structure.

[0025] It can be seen that the two battery packs 2 used in this embodiment improve the battery life compared to the existing one battery pack 2, avoiding battery life anxiety, and the battery packs 2 are placed in a T shape, which is beneficial to reducing the body width of the front of the vehicle compared to the horizontal side-by-side placement, and compared to the longitudinal side-by-side placement, the T-shaped placement reduces the wheelbase, thereby reducing the turning radius and further ensuring the turning performance. The installation method of this embodiment combines the advantages of the two battery pack 2 placement methods. Furthermore, due to the reduction in the front body width, the driver's riding experience is improved.

[0026] Furthermore, the accommodating bin of the present embodiment includes a supporting bottom surface 5 and supporting side surfaces, the bottom of the battery pack 2 is against the supporting bottom surface 5, the supporting side surfaces are surrounded by welded tubes, and the projection of the welded tubes located at the front end of the frame 1 on the horizontal plane is a trumpet shape. The trumpet shape makes the accommodating bin look like an inverted triangle structure as a whole, which reduces the interference of the vehicle body on the front fork during steering, has a larger turning space, and thus improves the turning performance of the whole vehicle, and is compatible with the T-shaped battery pack 2.

[0027] In order to improve the structure of the entire vehicle, the projection of the supporting side on the horizontal plane is a structure that is narrow in the front and wide in the back. The opening of the accommodating compartment is narrow in the front and wide in the back, which is more suitable for wrapping the T-shaped battery pack 2, thereby reducing the occupancy of the area below the seat cushion.

[0028] In addition, there is a protective shell inside the accommodating chamber, and the outer wall of the protective shell is fixedly connected to the corresponding welding pipe. The protective shell and the welding pipe are generally connected by bolts. This is a prior art and will not be repeated here. The bottom of the protective shell is provided with a plug-in male plate, which is installed on the supporting bottom surface 5. The bottom of the battery pack 2 is provided with a plug-in mother plate connected to the plug-in male plate. The battery pack 2 is inserted into the protective shell from the opening above the protective shell to provide all-round protection for the battery pack 2. After the plug-in mother plate at the bottom of the battery pack 2 is connected to the plug-in male plate, the entire vehicle can be powered on. This installation method is neater and avoids the messy connection harness between the battery packs 2.

[0029] Furthermore, the upper part of the frame 1 has two welded tubes 3 for installing the seat. The projection of the welded tube 3 on the horizontal plane is a structure that is narrow at both ends and wide in the middle. A number of ribs 4 are arranged horizontally between the two welded tubes 3. Bolt holes for installing the seat are opened on the ribs 4. The welded tube 3 is used as the bearing structure of the seat on the frame 1, and a number of ribs 4 are also arranged between the two welded tubes 3 to improve the strength and ensure the riding space and riding safety.

[0030] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
