[0004] The aforementioned patent cannot perform shock absorption on the assembled battery during use, and the battery cannot be quickly disassembled after use. Furthermore, it has insufficient internal heat dissipation and low functionality, failing to meet people's daily usage needs.

[0005] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Utility Model Content

[0006] The purpose of this utility model is to provide a detachable battery box assembly that can effectively solve the above-mentioned technical problems.

[0007] To achieve the purpose of this utility model, the following technical solution is adopted:

[0008] A detachable battery box assembly includes: a battery casing, a splitting assembly, and a clamping assembly;

[0009] The split assembly includes an upper housing, a first rod fixedly mounted on the upper housing, a limiting head fixedly mounted on the first rod, a sliding seat that moves in the limiting head, a sliding wheel that slides in the sliding seat, a second rod rotatably connected to the bottom of the sliding wheel, and a lower housing fixedly mounted on the surface of the second rod.

[0010] The sliding seat is hollow, and both the upper and lower ends of the sliding seat are designed to be wider at both ends and narrower in the middle.

[0011] Furthermore, the clamping assembly consists of a buffer, a clamping head, and a positioning rod; the buffer is fixedly connected to the clamping head, and the positioning rod is fixedly connected to the clamping head.

[0012] The buffer includes a fixed base, a spring, and a support head; the fixed base is fixedly connected to the spring, the other end of the spring is fixedly connected to the support head, and the other end of the support head is fixedly connected to the clamping head.

[0013] Furthermore, a heat sink is also installed on the battery casing, and the heat sink is placed vertically offset on the battery casing.

[0014] Furthermore, the clamping assembly is provided in multiple sets, and the support head is rounded.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0024] In the description of this utility model, it should be understood that the terms "center," "lateral," "longitudinal," "front," "rear," "left," "right," "upper," "lower," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model. When a mechanism is referred to as being "fixed to" another mechanism, it can be directly on the other mechanism or there may be an intervening mechanism. When a mechanism is considered to be "connected" to another mechanism, it can be directly connected to the other mechanism or there may be an intervening mechanism at the same time. When a mechanism is considered to be "set on" another mechanism, it can be directly set on the other mechanism or there may be an intervening mechanism at the same time. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.

[0025] like Figures 1 to 5 As shown, a detachable battery box assembly includes: a battery casing 1, a splitting component 3, and a clamping component 5.

[0026] Battery boxes are widely used in electric vehicles, energy storage systems, portable electronic devices, and other fields. Among these, electric vehicles are the primary application area for battery boxes, and they also have the highest requirements for the performance and quality of the battery boxes.

[0027] The splitting assembly 3 includes an upper housing 31, a first rod 32 fixedly mounted on the upper housing 31, a limiting head 33 fixedly mounted on the first rod 32, a sliding seat 34 that moves within the limiting head 33, a sliding wheel 36 that slides within the sliding seat 34, a second rod 35 rotatably connected to the bottom of the sliding wheel 36, and a lower housing 37 fixedly mounted on the surface of the second rod 35. The upper housing 31 is the top structure of the splitting assembly 3, which is usually used to house and protect the internal components of the assembly, and also serves as the mounting base for other components. The first rod 32 provides support and guidance for the limiting head 33, ensuring that the limiting head 33 remains stable and accurate during movement. When the operator moves the upper housing 31, the limiting head 33 moves along the sliding seat 34, while the sliding wheel 36 rotates within the sliding seat 34, without affecting the fixation of the lower housing 37, facilitating the separation of the upper housing 31 and the lower housing 37, and facilitating the splitting of the battery case 1.

[0028] The sliding seat 34 is hollow, and both the upper and lower ends of the sliding seat 34 are designed to be wider at both ends and narrower in the middle. The hollow design allows the sliding seat 34 to reduce its overall weight while maintaining the necessary strength and rigidity. At the same time, the upper and lower ends (i.e., the top and bottom) of the sliding seat 34 are wider at both ends and narrower in the middle in the lateral direction, which helps the sliding seat 34 to slide more stably on a specific track or path. The wider part can provide better support and guidance, preventing the sliding seat 34 from deviating or tilting during the sliding process.

[0029] The clamping assembly 5 consists of a buffer 52, a clamping head 51, and a positioning rod 53. The buffer 52 is fixedly connected to the clamping head 51, and the positioning rod 53 is also fixedly connected to the clamping head 51. During clamping, the buffer 52 effectively functions while maintaining synchronous movement with the clamping head 51. The clamping head 51 is fixedly connected not only to the buffer 52 but also to the positioning rod 53. This multiple connection method ensures that the clamping head 51 remains stable during clamping, preventing displacement or loosening. The main function of the positioning rod 53 is to determine the position and orientation of the clamping head 51, ensuring that the clamping head 51 can accurately position itself to the designated location of the object being clamped during clamping. The positioning rod 53 can also serve as a connection point for the clamping assembly 5, enabling coordinated movement of the entire assembly.

[0030] The clamping assembly 5 is provided in multiple sets, and the support head 523 is rounded. The multiple sets of clamping assemblies 5 can disperse the clamping force, reduce the pressure on a single clamping point, and thus reduce the risk of damaging the clamped object. At the same time, they can also provide more clamping points, making the clamping more uniform and stable, reducing the pressure on the battery, making the battery less susceptible to vibration, and preventing battery damage.

[0031] The buffer 52 includes a fixed base 521, a spring 522, and a support head 523. The fixed base 521 is fixedly connected to the spring 522, the other end of the spring 522 is fixedly connected to the support head 523, and the other end of the support head 523 is fixedly connected to the clamping head 51. When the clamping head 51 begins to contact and clamp the battery, a certain impact force is generated. This impact force is transmitted to the spring 522 through the support head 523. Due to its good elasticity and resilience, the spring 522 can absorb and disperse this impact force. The spring 522 deforms, stores energy, and reduces the direct impact of the clamping head 51 on the battery. At the same time, the deformation of the spring 522 also provides a buffer area, allowing the clamping head 51 to gradually adapt to the shape and size of the battery, ensuring the stability and reliability of the clamping.

[0032] A heat sink 4 is also installed on the battery casing 1, and the heat sink 4 is placed vertically offset on the battery casing 1. This offset design increases the contact area between the heat sink 4 and the battery casing 1, thereby improving heat dissipation efficiency. Secondly, by offsetting the placement, the heat sink 4 can better adapt to the shape and size of the battery casing 1, ensuring uniform and stable heat dissipation. In addition, it can also reduce the space occupied by the heat sink 4 inside the battery casing 1 to a certain extent, thereby improving the overall energy density of the battery.

[0033] Working principle:

[0034] When the operator moves the upper housing 31, the limiting head 33 moves along the sliding seat 34, while the sliding wheel 36 rotates within the sliding seat 34, without affecting the fixation of the lower housing 37. This facilitates the separation of the upper housing 31 and the lower housing 37, and the disassembly of the battery case 1. During the clamping process, the buffer 52 effectively functions, maintaining synchronous movement with the clamping head 51. The clamping head 51 is not only fixedly connected to the buffer 52 but also to the positioning rod 53. This multi-connection method ensures that the clamping head 51 remains stable during clamping, preventing displacement or loosening. The main function of the positioning rod 53 is to determine the position and orientation of the clamping head 51. Multiple clamping components 5 disperse the clamping force, reducing pressure on a single clamping point and thus lowering the risk of damaging the clamped object. Simultaneously, they provide more clamping points, making the clamping more uniform and stable, reducing pressure on the battery while preventing it from impacting the battery case and thus preventing battery damage.
