[0039] To address the technical problem that existing battery boxes typically use bolts, adhesives, or welding to fix the battery module 3 within the housing 1, which requires specific tools for assembly and disassembly of the battery module 3 and significantly impacts the efficiency of assembly and disassembly, this application provides a battery box and electric vehicle. The battery box housing 1 includes a snap-fit ​​assembly 2 and a quick-release component 4. Through the cooperation of the snap-fit ​​assembly 2 and the quick-release component 4, tool-free quick assembly and disassembly of the battery module 3 are achieved, greatly improving maintenance efficiency and saving time and labor costs.

[0040] Please see Figures 1 to 4The present application provides a battery box including a box body 1, a snap-fit ​​assembly 2, a battery module 3, and a quick-release component 4. The box body 1 has an installation groove 1a; the snap-fit ​​assembly 2 is connected to the inner wall of the installation groove 1a, and the snap-fit ​​assembly 2 has a snap-fit ​​space 2a; the battery module 3 is snapped into the snap-fit ​​space 2a; one end of the quick-release component 4 is connected to the battery module 3, and the other end of the quick-release component 4 is exposed in the snap-fit ​​space 2a and located at the opening of the installation groove 1a.

[0041] In this embodiment, the housing 1 is generally a cuboid or cube structure, made of high-strength aluminum alloy or other metal materials, possessing good mechanical strength and corrosion resistance. A mounting groove 1a is provided on one side to accommodate the battery module 3. A snap-fit ​​assembly 2 is connected to the inner wall of the mounting groove 1a. This snap-fit ​​assembly 2 can be multiple elastic elements or snap-fit ​​structures perpendicular to the direction of movement of the battery module. A snap-fit ​​space 2a is formed inside the snap-fit ​​assembly 2, the shape of which is adapted to the shape of the battery module 3. For example, when the battery module 3 is a cuboid, the snap-fit ​​space 2a is also cuboid in shape. The size of the snap-fit ​​space 2a is slightly larger than the size of the battery module 3 so that the battery module 3 can be smoothly inserted into the snap-fit ​​space 2a and secured. It should be noted that when the snap-fit ​​assembly 2 clamps the battery module by pressing it against the inner wall, the size of the snap-fit ​​space 2a can also be slightly smaller than the size of the battery module 3 to better clamp the battery module 3. The outer shell of battery module 3 is made of aluminum alloy, which has good heat dissipation performance and mechanical strength. Its size matches the snap-fit ​​space 2a, allowing it to be tightly snapped into place within the snap-fit ​​space 2a. The quick-release component 4 can be configured as a handle or pull cord, made of high-strength plastic or nylon. One end is connected to the outer shell of battery module 3 by a bolt, and the other end passes through the snap-fit ​​space 2a, protruding from the opening of the mounting slot 1a, facilitating quick disassembly by the operator. In practical applications, when it is necessary to disassemble battery module 3, the operator only needs to pull the handle or pull cord of quick-release component 4 to deform the snap-fit ​​component 2, releasing battery module 3 and allowing for easy removal. During installation, battery module 3 is aligned with the snap-fit ​​space 2a and inserted. The snap-fit ​​component 2 applies elastic force to battery module 3, firmly clamping it within the snap-fit ​​space 2a.

[0042] The combination of snap-fit ​​assembly 2 and quick-release component 4 enables tool-free quick assembly and disassembly of battery module 3, greatly improving maintenance efficiency and saving time and labor costs. The elastic element or snap-fit ​​structure design of snap-fit ​​assembly 2 ensures stable clamping force during frequent assembly and disassembly, while preventing damage to the battery module 3 casing. The housing 1 is made of high-strength aluminum alloy or other metal materials, possessing excellent mechanical strength and corrosion resistance, effectively protecting the battery module 3 from external environmental influences and extending its service life. Furthermore, the handle or pull cord structure of quick-release component 4 is simple and easy to operate, allowing for easy assembly and disassembly of battery module 3 even in confined spaces, further enhancing the user experience. This design not only improves the maintainability of the battery box but also reduces the risk of loose connections or damage that may result from traditional fixing methods, thereby improving the overall reliability and service life of the battery box. It is particularly suitable for fields such as new energy vehicles, meeting the needs of vehicle drivers for stable and quick replacement of battery module 3 during driving.

[0043] Please see Figures 1 to 3 In order to better clamp the battery module 3 with the snap-fit ​​assembly 2, and to ensure that the battery module 3 does not collide with the inner wall of the housing 1 unnecessarily, the snap-fit ​​assembly 2 has a snap-fit ​​part 21 and a buffer part 22. The snap-fit ​​part 21 is connected to the buffer part 22, the snap-fit ​​part 21 is connected to the inner side wall of the mounting groove 1a, and the buffer part 22 is connected to the bottom wall of the mounting groove 1a.

[0044] In this embodiment, the snap-fit ​​assembly 2 is specifically provided with a snap-fit ​​part 21 to snap the battery module 3. The snap-fit ​​part 21 can be configured as a slot, protrusion, or elastic claw, as long as it can limit the overall positioning of the battery module 3. The snap-fit ​​space 2a inside the snap-fit ​​assembly 2 can completely fit the battery module 3. The snap-fit ​​part 21 is connected to the inner wall of the mounting groove 1a by bolts or adhesive, and is firmly fixed to the housing 1. The buffer part 22 is generally made of rubber or foam material, and its thickness can be adjusted according to the gap between the battery module 3 and the bottom wall of the mounting groove 1a, generally between 5-10 mm. The buffer part 22 is connected to the bottom wall of the mounting groove 1a by adhesive or embedded installation, which can absorb the impact force when the battery module 3 is inserted, prevent it from colliding with the inner wall of the housing 1, and reduce the impact of vibration on the battery module 3 during vehicle operation.

[0045] Please see Figures 1 to 4 Because the structure such as the slot, protrusion, or elastic claw will wear on the outer surface of the battery module 3, the service life of the battery module 3 will be shortened. Both the latching part 21 and the buffer part 22 are made of soft materials and can be compressed.

[0046] In one embodiment, the latching part 21 and the buffer part 22 are generally made of soft materials, such as elastic rubber or foam, and their structure is an integral elastic clamping member. The battery module 3 is fixed by compressing its outer wall through the elastic deformation of the material. The inner surface of the latching part 21 is designed to match the shape of the outer surface of the battery module 3, such as an arc or a plane, to ensure a tight fit. The latching part 21 is connected to the inner wall of the mounting groove 1a by bolts or adhesive, and is firmly fixed to the housing 1. The latching part 21 compresses the battery module 3 through material deformation, ensuring the stability of the battery module 3 after installation. Even when encountering bumps during vehicle operation, the battery module 3 is firmly fixed, preventing it from loosening or shifting. The flexible material design of the buffer part 22 effectively avoids direct collision between the battery module 3 and the inner wall of the housing 1, reducing the risk of damage to the outer casing or failure of internal components due to collision.

[0047] Please see Figure 4 In order to keep the pressure of the snap-fit ​​assembly 2 on the outer wall of the battery module 3 within a suitable range, the size of the snap-fit ​​space 2a needs to match the battery module 3. Specifically, the orthographic projection of the snap-fit ​​space 2a on the bottom of the mounting groove 1a is smaller than the orthographic projection of the battery module 3 on the bottom of the mounting groove 1a.

[0048] In this embodiment, the design of the snap-fit ​​component 2 ensures that the pressure applied to the outer wall of the battery module 3 remains within a suitable range. Specifically, the size of the snap-fit ​​space 2a matches that of the battery module 3, and the orthographic projection of the snap-fit ​​space 2a onto the bottom of the mounting groove 1a is smaller than the orthographic projection of the battery module 3 onto the bottom of the mounting groove 1a. This dimensional design allows the material of the snap-fit ​​component 2 to apply a certain pressure to the battery module 3 due to deformation when the battery module 3 is inserted into the snap-fit ​​space 2a, thereby achieving stable clamping. The material of the snap-fit ​​component 2 can be foam, whose elastic modulus ensures appropriate deformation when the battery module 3 is inserted, while maintaining a stable clamping force during use. For example, the snap-fit ​​component 2 can be designed as an integral elastic clamping member, with its inner surface tightly fitting the outer surface of the battery module 3, applying pressure through the elastic deformation of the material. During installation, the bottom edge of the battery module 3 will slightly extend beyond the bottom edge of the snap-fit ​​space 2a, ensuring that the snap-fit ​​component 2 can evenly squeeze the battery module 3 from all sides, thereby achieving stable fixation.

[0049] This embodiment of the application ensures that the pressure applied by the snap-fit ​​assembly 2 to the outer wall of the battery module 3 remains within a suitable range by precisely matching the size of the snap-fit ​​space 2a with that of the battery module 3. This design not only effectively secures the battery module 3, preventing it from loosening or shifting during driving, but also avoids damage to the battery module 3 due to excessive pressure. For example, by designing the size of the snap-fit ​​space 2a to be slightly smaller than the size of the battery module 3, the snap-fit ​​assembly 2 can generate appropriate elastic deformation when the battery module 3 is inserted, thereby applying uniform pressure and ensuring the stability of the battery module 3. In addition, this design can also reduce the gap between the battery module 3 and the snap-fit ​​assembly 2 caused by size mismatch, further improving the sealing and protection performance of the battery box. Specifically, the orthographic projection of the snap-fit ​​space 2a on the bottom of the mounting groove 1a is smaller than the orthographic projection of the battery module 3, which ensures that the battery module 3 is evenly squeezed from all sides by the snap-fit ​​assembly 2 when inserted, thereby achieving stable fixation, while avoiding direct collision between the battery module 3 and the inner wall of the box 1, extending the service life of the battery module 3. This design is particularly suitable for fields such as new energy vehicles, and can meet the high requirements for the stability and reliability of battery module 3 during vehicle operation.

[0050] Please see Figures 1 to 4 In order to ensure the stability of the clamping component 2 and the battery module 3 to be better installed and removed in the mounting groove 1a, the clamping component 2 has four clamping parts 21. The four clamping parts 21 extend along the direction from the bottom to the opening of the mounting groove 1a. The four clamping parts 21 are located at the four edges of the line connecting the opening and the bottom of the mounting groove 1a.

[0051] In this application, the snap-fit ​​assembly 2 has four snap-fit ​​portions 21, each extending along the direction from the bottom to the opening of the mounting groove 1a, and located at one of the four edges of the line connecting the opening and bottom of the mounting groove 1a. This arrangement ensures that the snap-fit ​​assembly 2 applies force evenly in four directions, thereby stably clamping the battery module 3. Each snap-fit ​​portion 21 can be designed as a thin, elastic structure, and its material can be foam. By providing snap-fit ​​portions 21 at the four edges of the mounting groove 1a, each snap-fit ​​portion 21 can make close contact with the outer wall of the battery module 3 and apply appropriate clamping force when the battery module 3 is inserted into the mounting groove 1a. This design not only ensures the secure fixation of the battery module 3 in the mounting groove 1a, but also avoids the problem of loosening or displacement of the battery module 3 due to uneven clamping force. Meanwhile, all four snap-fit ​​parts 21 extend along the bottom to the opening of the mounting groove 1a, making the battery module 3 easier to insert and remove, and reducing friction and wear during installation and disassembly.

[0052] Please see Figures 2 to 4Since conventional handle structures require connection to battery module 3 via bolts or other structures, and handles also occupy space inside the housing 1, which is not conducive to simplifying the overall structure, quick-release parts 4 have a lifting section 41 and a connecting section 42 connected to each other. The lifting section 41 is exposed in the snap-fit ​​space 2a, and the connecting section 42 is bonded to the outer wall of battery module 3.

[0053] In one embodiment, the quick-release component 4 is designed to simplify the assembly and disassembly process of the battery module 3 and reduce the space occupied inside the housing 1. The quick-release component 4 consists of a lifting section 41 and a connecting section 42. The lifting section 41 is exposed in the snap-fit ​​space 2a, facilitating direct operation by the operator, while the connecting section 42 is bonded to the outer wall of the battery module 3. This design avoids the use of bolts or other connecting components, thus reducing the space occupied inside the housing. The quick-release component 4 is designed as a woven adhesive tape, with one side of the connecting section 42 covered in adhesive. This adhesive side is adhered to the side wall of the battery module 3, while the lifting section 41 is non-adhesive, facilitating gripping and force application by the operator. The connecting section 42 can use a high-strength adhesive, such as epoxy resin or polyurethane glue, to ensure a firm connection to the outer wall of the battery module 3. Through this structure, the quick-release component 4 can quickly release the battery module 3.

[0054] Please see Figures 2 to 4 In order to enable the battery module 3 to be removed from the snap-fit ​​space 2a, the battery box has multiple quick-release parts 4, each quick-release part 4 being spaced apart on the outer side wall of the battery module 3.

[0055] To more efficiently remove the battery module 3 from the latching space 2a, the battery box is designed with multiple quick-release pieces 4, which are spaced apart on the outer wall of the battery module 3. Specifically, the number of quick-release pieces 4 can be adjusted according to the size and shape of the battery module 3, typically evenly distributed on both sides or around the battery module 3. For example, for a cuboid-shaped battery module 3, two quick-release pieces 4 can be placed on each side of its long side, for a total of four quick-release pieces 4. Each quick-release piece 4 includes a lifting section 41 and a connecting section 42. The lifting section 41 is exposed in the latching space 2a for easy operation by the operator, while the connecting section 42 is bonded to the outer wall of the battery module 3 with a high-strength adhesive. The quick-release pieces 4 can be made of high-strength plastic or composite materials to ensure durability and reliability. This design allows the operator to easily remove the battery module 3 from the latching space 2a by applying force from multiple directions, while also ensuring that the battery module 3 is securely fixed during installation. The design of multiple quick-release clips 4 allows operators to apply force from multiple directions, reducing the risk of damage to the battery module 3 or deformation of the locking assembly 2 that may occur due to single-point force application. At the same time, the spacing of the quick-release clips 4 ensures balanced force on the battery module 3 during installation and removal, further improving the safety and reliability of the operation.

[0056] Please see Figures 1 to 3 In order to ensure the integrity of the overall structure of the battery box and to ensure its normal use, the battery box also includes a cover 5, which is detachably installed in the groove of the mounting slot 1a of the box body 1.

[0057] To ensure the overall structural integrity and normal use of the battery box, the battery box of this application also includes a cover 5. The cover 5 is designed to match the shape of the mounting groove 1a of the box 1. For example, if the mounting groove 1a is rectangular, the cover 5 is also rectangular, with dimensions slightly larger than the opening size of the mounting groove 1a, to ensure good sealing and stability. The cover 5 is detachably installed on the box 1, for example, by using a snap-fit ​​structure or threaded connection to achieve quick installation and removal. The cover 5 can be made of high-strength plastic or aluminum alloy to ensure sufficient mechanical strength and corrosion resistance. For example, the edge of the cover 5 can be designed with snaps that cooperate with the slots on the box 1 to achieve quick fixing and removal. When maintenance or replacement of the battery module 3 is required, the operator only needs to gently press the snaps to open the cover 5, exposing the battery module 3 in the mounting groove 1a for the corresponding operation.

[0058] Please see Figures 1 to 3 To prevent the top of the battery module 3 from colliding with the cover 5, a top wall buffer 6 is provided between the cover 5 and the battery module 3. When the cover 5 is connected to the housing 1, the two ends of the top wall buffer 6 abut against the cover 5 and the battery module 3 respectively.

[0059] To prevent collisions between the top of the battery module 3 and the cover 5, a top wall buffer 6 is installed between the cover 5 and the battery module 3. The top wall buffer 6 is made of flexible materials, such as rubber, silicone, or polyurethane foam, which have good elasticity and cushioning properties. The shape of the top wall buffer 6 can be designed to match the top of the battery module 3 as a flat or circular shape, with a thickness generally between 5-10 mm to ensure sufficient cushioning space. During installation, the two ends of the top wall buffer 6 abut against the top of the cover 5 and the top of the battery module 3, respectively. The top wall buffer 6 can be fixed to the inner surface of the cover 5 with adhesive. When the cover 5 is connected to the housing 1, the top wall buffer 6 effectively absorbs the impact force between the cover 5 and the battery module 3, preventing damage to the battery module 3 from the collision. This design not only protects the battery module 3 but also improves the overall reliability and service life of the battery housing.

[0060] Please see Figure 3 Since the sidewall of the battery module 3 is only buffered by the aforementioned snap-fit ​​assembly 2 and the inner wall of the housing 1, this protection is not comprehensive. Therefore, the snap-fit ​​assembly 2 also includes multiple sidewall buffers 23, each of which is connected to the inner wall of the housing 1.

[0061] To further enhance the protective performance of the battery module 3, the snap-fit ​​assembly 2 not only includes a snap-fit ​​portion 21 for clamping the battery module 3, but also adds multiple sidewall buffers 23. These sidewall buffers 23 are distributed around the sidewalls of the battery module 3 and connected to the inner wall of the housing 1 to provide additional cushioning protection. Specifically, the sidewall buffers 23 can be made of flexible materials, such as rubber, silicone, or polyurethane foam, which have good elasticity and cushioning properties. The sidewall buffers 23 can be designed in a long strip shape, with dimensions matching the sidewalls of the battery module 3 to ensure a tight fit. The sidewall buffers 23 can be fixed to the inner wall of the housing 1 with adhesive. When the battery module 3 is inserted into the mounting slot 1a, the sidewall buffers 23 can fit tightly against the sidewalls of the battery module 3, absorbing impact forces and vibrations from all directions, thereby providing comprehensive protection for the battery module 3. This design not only enhances the stability of the battery module 3, but also reduces the risk of damage caused by collisions or vibrations.

[0062] Secondly, please refer to Figures 1 to 3 This application provides an electric vehicle, including the battery box provided in the first aspect of this application.

[0063] This application provides an electric vehicle whose core component is the battery box described in the first aspect above. The design of this battery box fully considers the needs for fixing, protecting, and quickly installing / removing the battery module 3. By adopting the aforementioned battery box design, the electric vehicle of this application significantly improves the safety and maintenance efficiency of the battery system. The snap-fit ​​component 2 and buffer design of the battery box effectively protect the battery module 3 from external impacts and vibrations, extending the service life of the battery module 3 and ensuring stable operation of the electric vehicle under various complex road conditions. The quick-release component 4 makes the installation and removal of the battery module 3 more convenient, allowing for quick completion without tools, greatly improving maintenance and replacement efficiency and reducing operating costs. Furthermore, the high-strength aluminum alloy material and excellent sealing design of the battery box further enhance the reliability and durability of the battery system. This design is particularly suitable for electric vehicle applications requiring frequent replacement of the battery module 3, such as shared electric vehicles or electric taxis with rapid battery swapping, effectively improving user experience and providing strong support for the large-scale commercial application of electric vehicles.
