Description

Technical Field

[0001] This utility model relates to the field of motorcycle frame technology, specifically to a frame structure for securely mounting battery packs on new energy motorcycles. Background Technology

[0002] As a green mode of transportation, the ease and stability of battery pack installation are crucial to the user experience of new energy motorcycles. In existing technologies, the connection between the battery pack and the frame mostly relies on bolt fixing structures. This method requires specialized tools for installation and disassembly, making the process cumbersome and time-consuming. When the battery pack needs routine maintenance or replacement, the lengthy disassembly and assembly process not only reduces operational efficiency but also increases the user's burden. Therefore, this utility model proposes a stable battery pack mounting structure for new energy motorcycles to solve the above problems. Utility Model Content

[0003] The purpose of this utility model is to provide a stable mounting structure for the battery pack of a new energy motorcycle to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a battery pack for a new energy motorcycle is securely mounted on a frame structure, including a frame body, a fixed support plate welded to the frame body, a fixed box fixed to the fixed support plate, a battery assembly inside the fixed box, and pushing components for limiting and fixing the battery assembly on all four sides of the inner wall of the fixed box. The pushing components include a movable push plate disposed inside the fixed box and a driving component for driving the movable push plate to fit tightly against the outer wall of the battery assembly.

[0005] Preferably, the driving component includes a fixed seat fixedly installed on the inner wall of the fixed box, a sliding plate slidably connected inside the fixed seat, and a push plate hinged to the lower end of the sliding plate.

[0006] Preferably, a movable push plate is hinged to the end of the push plate away from the sliding plate, and a sliding connecting rod is fixedly connected to one end of the movable push plate.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1 to 4This utility model provides a technical solution: a battery pack for a new energy motorcycle is securely mounted on a frame structure, including a frame body 1, a fixed support plate 2 welded to the frame body 1, a fixed box 3 fixed to the fixed support plate 2, a battery assembly 4 disposed inside the fixed box 3, and pushing components for limiting and fixing the battery assembly 4 are provided around the inner wall of the fixed box 3. The pushing components include a movable push plate 5 disposed inside the fixed box 3 and a driving component for driving the movable push plate 5 to be in close contact with the outer wall of the battery assembly 4. In actual use, an anti-slip pad is provided on the movable push plate 5 near the battery assembly 4. The anti-slip pad can be made of rubber, which has good elasticity and friction. The push assembly eliminates the need for special tools; simply operating the sliding plate 9 drives the movable push plate 5 to limit and fix the battery assembly 4 from four directions. This solves the problem of cumbersome disassembly and assembly of existing bolt-fixed methods, significantly improving the efficiency of battery assembly 4 installation and disassembly, and facilitating daily maintenance, replacement, or charging operations. Simultaneously, the sliding insert 11, under the action of the connecting spring 13, engages in the locking groove 14, quickly limiting the sliding plate 9 and ensuring the movable push plate 5 stably presses against the battery assembly 4, guaranteeing the battery assembly 4's stability during vehicle operation. When disassembly is required, simply pull the sliding insert 11 to disengage it from the locking groove 14, and the return spring 7 will drive the movable push plate 5 to return to its original position, making operation convenient.

[0019] like Figure 4 As shown, the driving component includes a fixed seat 10 welded to the inner wall of the fixed box 3. A sliding plate 9 is slidably connected inside the fixed seat 10. A push plate 8 is hinged to the lower end of the sliding plate 9. A movable push plate 5 is hinged to the end of the push plate 8 away from the sliding plate 9. A sliding connecting rod 6 is welded and fixed to one end of the movable push plate 5. The sliding connecting rod 6 slides through the box wall of the fixed box 3. A return spring 7 is sleeved on the sliding connecting rod 6. A locking element for locking the sliding plate 9 is provided on the sliding plate 9. When a downward pressing force is applied to the sliding plate 9 around the inner wall of the fixed box 3, the sliding plate 9 drives the sliding connecting rod 6 to move through the push plate 8, thereby causing the movable push plate 5 connected to the sliding connecting rod 6 to move towards the battery assembly 4. At this time, the return spring 7 sleeved on the sliding connecting rod 6 is stretched.

[0020] like Figure 3 as well as Figure 4As shown, the locking component includes a sliding insert plate 11 slidably disposed inside the sliding plate 9 and a locking groove 14 formed on the fixed box 3 for the sliding insert plate 11 to be inserted into. A fixed connecting plate 12 is welded to one end of the sliding insert plate 11, and a connecting spring 13 is welded to one end of the fixed connecting plate 12. The end of the connecting spring 13 away from the fixed connecting plate 12 is welded to the sliding plate 9. When the moving push plate 5 presses against the outer wall of the battery assembly 4, the sliding insert plate 11 on the sliding plate 9 moves to the position of the locking groove 14 on the fixed seat 10 under the elastic force of the connecting spring 13 and is inserted into the locking groove 14, thereby limiting and fixing the sliding plate 9.

[0021] In actual use, when the battery pack of this new energy motorcycle is securely installed on the frame structure, the battery assembly 4 is first placed inside the fixed box 3. Then, a downward pressing force is applied to the sliding plates 9 around the inner wall of the fixed box 3. The sliding plates 9 drive the sliding connecting rod 6 to move through the pushing plate 8, thereby causing the moving push plate 5 connected to the sliding connecting rod 6 to move closer to the battery assembly 4. At this time, the return spring 7 sleeved on the sliding connecting rod 6 is stretched. When the moving push plate 5 presses against the outer wall of the battery assembly 4, the sliding insert plate 11 on the sliding plate 9 moves to the locking groove 14 position on the fixed seat 10 under the elastic force of the connecting spring 13 and locks in place. The sliding plate 9 is fixed in the locking groove 14. Following the same operation, the sliding plates 9 around the fixed box 3 are pressed in sequence, so that the moving push plates 5 in all four directions are pressed against the outer wall of the battery assembly 4 and completed in a limiting manner. This forms a stable clamping and fixing of the battery assembly 4 from all sides, ensuring the installation stability of the battery assembly 4 in the fixed box 3. When it is necessary to remove the battery assembly 4, the fixing connecting plate 12 is pulled outward to make the sliding insert plate 11 disengage from the locking groove 14. At this time, the elastic force of the return spring 7 drives the sliding connecting rod 6 and the moving push plate 5 to return to their original positions, releasing the clamping of the battery assembly 4, and the battery assembly 4 can be taken out of the fixed box 3.

[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
