Description

Technical Field

[0001] This utility model specifically relates to a battery charging and discharging testing device, belonging to the field of battery testing technology. Background Technology

[0002] A battery is a cup, tank, or other container or composite container containing an electrolyte solution and metal electrodes to generate current. It is a device that converts chemical energy into electrical energy and has positive and negative electrodes. With the advancement of technology, the term "battery" now generally refers to any small device that can generate electrical energy, such as a solar cell. The main performance parameters of a battery are electromotive force, capacity, specific energy, and resistance. Using a battery as an energy source can provide a stable voltage, stable current, long-term stable power supply, and a current that is minimally affected by external factors. Furthermore, batteries have a simple structure, are easy to carry, and are simple to charge and discharge. They are unaffected by external climate and temperature, and their performance is stable and reliable. They play a significant role in various aspects of modern life. A battery tester is a device for real-time and comprehensive online detection and management of power system batteries. It is widely used in the management of power storage batteries in industries such as power, communications, transportation, and automobiles.

[0003] A search revealed a Chinese patent with publication number CN216956286U, which discloses a battery charging and discharging testing device. This patent utilizes a sliding groove, a sliding plate, and an elastic mechanism. The sliding plate, under the elastic potential energy provided by a compression spring, can be inserted into the snap-fit ​​groove, thus connecting the snap-fit ​​plate to the snap-fit ​​interface. A toggle plate can then be used to separate the sliding plate from the snap-fit ​​groove, facilitating disassembly of the snap-fit ​​plate and the snap-fit ​​interface. This method facilitates secondary disassembly of the heat dissipation mesh, making cleaning easier and improving device convenience. However, this testing device requires disassembly and cleaning of the heat dissipation mesh, lacking the ability to automatically clean it during equipment use. Manual disassembly and cleaning of the heat dissipation mesh can lead to dust or fibers clogging the mesh during use. Especially in industrial environments with high-frequency charging and discharging tests (such as power battery production lines), the heat dissipation mesh may need cleaning 2-3 times per month, but manual cleaning is inherently delayed. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a battery charging and discharging testing device. This device facilitates the quick disassembly of the mounting bracket and the replacement or cleaning of the brushes. Driven by a motor, the rotating brushes clean the dust from the surface of the heat dissipation mesh, preventing clogging. The rotating fan blades assist the testing instrument in venting and cooling the device, accelerating airflow through the heat dissipation mesh, thus forming a dual-effect cycle of "cleaning + cooling". The cleaned dust is blown away from the device by the airflow, preventing secondary adhesion and achieving online cleaning. This avoids heat dissipation failure caused by delayed cleaning.

[0005] A battery charge / discharge testing device includes: a testing instrument body, a quick-release mechanism, a cleaning structure, and a heat dissipation grid; A cleaning mechanism includes a cleaning component and a driving component, wherein the cleaning component is used to rotate and clean the heat dissipation mesh, and the driving component is used to provide driving force to the cleaning component; The cleaning component includes a mounting bracket and a brush. The brush is disposed inside the mounting bracket, which is located on one side of the heat dissipation mesh, and the brush is in contact with the heat dissipation mesh. The drive assembly includes a motor and a rotating shaft. One end of the rotating shaft is connected to the output end of the motor. The mounting bracket is detachably mounted on the other end of the rotating shaft. Fan blades are detachably mounted on the outer side of the rotating shaft and are located on the other side of the heat dissipation mesh.

[0006] Furthermore, a handle is provided at the top of the detector body, and a protective cover is provided on the outside of the handle.

[0007] Furthermore, the quick-release mechanism includes a first locking plate and an assembly cylinder. Multiple sets of the first locking plates are arranged in a circular array at the heat dissipation port of the detector body. The assembly cylinder locking mechanism is located inside the assembly cylinder. A through slot corresponding to the first locking plate is provided on the outer side of the assembly cylinder.

[0008] Furthermore, the inner wall of the assembly cylinder is provided with multiple sets of limiting shells, and a first magnet is provided inside the multiple sets of limiting shells.

[0009] Furthermore, each of the multiple sets of limiting shells is provided with a second magnet, which is magnetically attracted to the first magnet. An assembly frame is provided between the multiple sets of second magnets, and the assembly frame is located on one side of the motor. The rotating shaft can rotatably pass through the interior of the assembly frame.

[0010] Furthermore, each of the multiple sets of limiting shells is provided with a No. 3 magnet inside. The heat dissipation mesh is connected to one side of the multiple sets of No. 3 magnets. The heat dissipation mesh is detachably located inside the assembly cylinder, and the rotating shaft moves through the interior of the heat dissipation mesh.

[0011] Furthermore, the cleaning mechanism also includes a positioning assembly, which includes a second positioning plate and a positioning plate. The second positioning plate is disposed on one side of the rotating shaft, wherein the inner side of the second positioning plate contacts the outer side of the mounting frame. The positioning plate is U-shaped, wherein the positioning plate can penetrate the second positioning plate and be inserted into the mounting frame. A limit rod is provided on one side of the second positioning plate, and the positioning plate is movably sleeved on the outer side of the limit rod. A spring is provided on the outer side of the limit rod. Beneficial effects

[0012] Equipped with a cleaning mechanism, the cleaning component can be detachably assembled and disassembled at one end of the rotating shaft using a locking assembly. This facilitates quick disassembly of the mounting bracket for brush replacement or cleaning. Driven by a motor, the rotating shaft rotates, which in turn rotates the fan blades and brushes. The rotating brushes clean dust from the surface of the heat dissipation mesh, preventing clogging of the mesh. The rotating fan blades assist the detector body in exhausting and dissipating heat, accelerating airflow through the heat dissipation mesh, forming a dual-effect cycle of "cleaning + heat dissipation." The cleaned dust is blown away from the equipment by the airflow, preventing secondary adhesion and achieving online cleaning. This avoids heat dissipation failure caused by delayed cleaning.

[0013] Equipped with a quick-release mechanism, the assembly frame can be limited in movement using a limiting shell. The assembly frame is positioned inside the assembly cylinder by magnetic attraction between the second magnet on the outside of the assembly frame and the first magnet. The heat dissipation mesh is then positioned and assembled by the limiting shell using the third magnet on one side of the heat dissipation mesh. After the third magnet contacts and magnetically attracts the second magnet, the heat dissipation mesh can be positioned and assembled. The assembled heat dissipation mesh can be fitted onto the outside of the rotating shaft. The detachable design of the assembly frame and the heat dissipation mesh facilitates disassembly and assembly in the future, accommodating both automatic cleaning and manual maintenance needs of the heat dissipation mesh.

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.

[0017] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, a battery charge / discharge testing device; Includes: the main body of the detector 1, a quick-release mechanism, a cleaning structure, and a heat dissipation mesh 19; The cleaning mechanism includes a cleaning component and a drive component. The cleaning component is used to rotate and clean the heat dissipation mesh 19, and the drive component is used to provide driving force to the cleaning component. The cleaning component includes a mounting bracket 17 and a brush 18. The brush 18 is disposed inside the mounting bracket 17, which is located on one side of the heat dissipation mesh 19. The brush 18 is in contact with the heat dissipation mesh 19. The drive assembly includes a motor 10 and a rotating shaft 11. One end of the rotating shaft 11 is connected to the output end of the motor 10. The mounting bracket 17 is detachably mounted on the other end of the rotating shaft 11. A fan blade 12 is detachably mounted on the outside of the rotating shaft 11. The fan blade 12 is located on the other side of the heat dissipation mesh 19. The cleaning mechanism also includes a positioning assembly, which includes a second positioning plate 13 and a positioning plate 16. The second positioning plate 13 is located on one side of the rotating shaft 11, and the inner side of the second positioning plate 13 contacts the outer side of the mounting bracket 17. The positioning plate 16 is U-shaped and can penetrate the second positioning plate 13 and be inserted into the mounting bracket 17. A limit rod 14 is provided on one side of the second positioning plate 13, and the positioning plate 16 is movably sleeved on the outer side of the limit rod 14. A spring 15 is provided on the outer side of the limit rod 14.

[0018] The cleaning component can be detachably assembled and disassembled at one end of the rotating shaft 11 using the locking component. After the mounting bracket 17 is inserted into one end of the rotating shaft 11, the limiting rod 14 on one side of the second locking plate 13 limits the movement of the "U"-shaped positioning plate 16. The elastic force of the spring 15 on the outside of the limiting rod 14 elastically squeezes the positioning plate 16. When the positioning plate 16 passes through the second locking plate 13 and is inserted into the mounting bracket 17, the mounting bracket 17 can be detachably positioned at one end of the rotating shaft 11. At this time, the brush 18 on the inside of the mounting bracket 17 contacts the heat dissipation mesh 19. Driven by motor 10, the rotating shaft 11 can rotate. The rotation of the rotating shaft 11 can drive the fan blade 12 and brush 18 to rotate. The rotation of brush 18 can clean the dust on the surface of heat dissipation mesh 19 and prevent the mesh from being blocked. The rotation of fan blade 12 can assist the detector body 1 in exhausting and dissipating heat, accelerating the airflow through heat dissipation mesh 19, forming a "cleaning + heat dissipation" dual-effect cycle. The cleaned dust will be blown away from the equipment by the airflow to avoid secondary adhesion, realize online cleaning, and avoid heat dissipation failure caused by cleaning delay.

[0019] Please see Figure 1 As shown, a battery charge / discharge testing device; The top of the detector body 1 is provided with a handle 2, and the outside of the handle 2 is covered with a protective cover.

[0020] The main body 1 of the detector is the main structure of the battery charge and discharge testing equipment, which integrates the battery charge and discharge test circuit, data acquisition module and heat dissipation system. The protective cover wrapped around the handle 2 makes it easy to carry. The protective cover is anti-slip and anti-static, and is suitable for industrial environments.

[0021] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a battery charge / discharge testing device; The quick-release mechanism includes a first positioning plate 3 and an assembly cylinder 4. Multiple sets of first positioning plates 3 are arranged in a circular array at the heat dissipation port of the detector body 1. The positioning and disassembly of the assembly cylinder 4 are located inside the assembly cylinder 4. A through groove 5 corresponding to the first positioning plate 3 is opened through the outside of the assembly cylinder 4.

[0022] Multiple sets of No. 1 positioning plates 3 are positioned at the heat dissipation port of the detector body 1. The assembly cylinder 4 can be inserted into the multiple sets of No. 1 positioning plates 3 by using the through slot 5. Then, the assembly cylinder 4 is rotated to make the through slot 5 and the No. 1 positioning plate 3 misaligned. The multiple sets of No. 1 positioning plates 3 can be used to position and assemble the assembly cylinder 4 at the heat dissipation port of the detector body 1, which is convenient for the assembly cylinder 4 to be disassembled and repaired later.

[0023] Please see Figure 2 , Figure 3 , Figure 4 and Figure 7 As shown, a battery charge / discharge testing device; The inner wall of the assembly cylinder 4 is provided with multiple sets of limiting shells 6.

The assembly frame 8 is located on one side of the motor 10. The rotating shaft 11 can rotate through the interior of the assembly frame 8. A third magnet 20 is provided inside each of the multiple sets of limiting shells 6. The heat dissipation mesh 19 is connected to one side of the multiple sets of third magnets 20. The heat dissipation mesh 19 is detachable and located inside the assembly cylinder 4. The rotating shaft 11 can move through the interior of the heat dissipation mesh 19.

[0024] The assembly cylinder 4 has multiple sets of limiting shells 6 on its inner wall, each equipped with a first magnet 7. The limiting shells 6 can be used to limit the movement of the assembly frame 8. The second magnet 9 on the outside of the assembly frame 8 comes into contact with the first magnet 7 and magnetically attracts it, which can position the assembly frame 8 inside the assembly cylinder 4. The third magnet 20 on one side of the heat dissipation mesh 19 is limited by the limiting shells 6. When the third magnet 20 comes into contact with the second magnet 9 and magnetically attracts it, the heat dissipation mesh 19 can be positioned and assembled. The assembled heat dissipation mesh 19 can be fitted onto the outside of the rotating shaft 11. The assembly frame 8 and the heat dissipation mesh 19 are detachable, which facilitates the disassembly and assembly of the assembly frame 8 and the heat dissipation mesh 19 in the future, and takes into account the needs of automatic cleaning and manual maintenance of the heat dissipation mesh 19.
