[0002] With the rapid development of new energy technologies, lithium batteries, as a high-efficiency and clean energy storage device, are widely used in electric vehicles, power tools, energy storage equipment, and many other fields. The charging process is crucial in the use of lithium batteries, and since lithium battery packs typically consist of multiple individual lithium batteries, efficient and safe charging requires specialized mounting equipment. Currently, existing lithium battery charging trays on the market have some shortcomings in use. On the one hand, they are not very effective at securing individual lithium batteries. During charging, individual lithium batteries are easily displaced by external impacts or vibrations, which may not only affect the stability of charging but also cause the charging interface to loosen, posing a safety hazard. On the other hand, most existing charging trays are not easy to move or are difficult to secure stably after being moved to a designated position. This greatly reduces the convenience of use when charging lithium battery packs in multiple locations.

[0003] To address these issues, this invention provides a lithium battery pack charging bracket. Utility Model Content

Beneficial effects

[0012] This invention provides a lithium battery pack charging bracket. Compared with the prior art, it has the following advantages: 1. This lithium battery pack charging bracket achieves stable fixation and efficient charging of individual lithium batteries through the collaborative operation of multiple components. The bottom plate, front and rear side plates, and sliding clamps work together to clamp the battery from the front and rear. Combined with the self-locking function of the first screw and the limit rod, it prevents the battery from shifting due to collisions and vibrations. Furthermore, multiple sockets are connected in parallel to ensure that each battery receives a stable current, preventing uneven current from affecting its lifespan. At the same time, the failure of a single socket does not affect the whole system. The screw lubricant reduces friction and extends the life of components, greatly improving charging stability, safety, and equipment durability, and solving the problems of poor fixation and low charging efficiency of traditional brackets.

[0013] 2. This lithium battery pack charging bracket features a bottom stabilizing component that balances mobility and stability. Four omnidirectional wheels allow for easy movement between multiple locations, meeting various charging needs. The stabilizing plate can be raised and lowered via a second screw, providing stable support when lowered and in close contact with the ground. Combined with the screw's self-locking function and the omnidirectional wheel brakes, the bracket remains stable during charging. The rubber material and anti-slip texture of the stabilizing plate further enhance the anti-slip effect, allowing the bracket to move flexibly to accommodate multiple charging points while ensuring stable parking for charging safety, thus improving ease of use and adaptability to different scenarios.

[0018] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0019] Reference Figures 1 to 4 This application provides a lithium battery pack charging bracket, including a base plate 1. The base plate 1 is made of high-strength alloy material, which has good load-bearing capacity and corrosion resistance, and can provide stable foundation support for the entire bracket. A fixing component 2 is provided on the top of the base plate 1, and a stabilizing component 3 is provided on the bottom of the base plate 1. The fixing assembly 2 includes multiple bottom plates 21, which are bolted to the top of the base plate 1. The number of bottom plates 21 can be set according to the number of individual lithium batteries 10 that need to be charged. In this embodiment, there are four bottom plates 21, which are evenly distributed on the top of the base plate 1. The individual lithium batteries 10 are placed on the top of the bottom plates 21. A bracket 4 is welded to the rear of the top of the base plate 1. The bracket 4 is made of stainless steel and has high strength and stability. A socket 5 and a placement plate 6 are fixed to the front of the bracket 4 with screws. The placement plate 6 is located above the individual lithium batteries 10. The placement plate 6 is made of plastic and has an anti-slip surface. It can be used to place small tools or accessories of the individual lithium batteries 10 required during charging. The socket 5 is located above the placement plate 6. The socket 5 is matched with the charging interface of the individual lithium batteries 10 to ensure a stable connection. Side plates 22 are welded and fixed to both the front and rear sides of the bottom plate 21. The side plates 22 are perpendicular to the bottom plate 21, and the back of the single lithium battery 10 is attached to the front of the side plate 22. The side plates 22 limit the back of the single lithium battery 10. A groove is formed on the top of the bottom plate 21, and a slider is fixedly installed on the bottom of the clamping plate 23. The slider is slidably connected inside the groove, so that the clamping plate 23 can slide on the top of the bottom plate 21 and is attached to the front of the single lithium battery 10. The front of the clamping plate 23 is rotatably connected to a first screw 24 via a bearing. A threaded hole is provided inside the side plate 22, through which the first screw 24 is screwed. A first knob 25 is fixedly installed on the front of the first screw 24 by welding. The outer side of the first knob 25 has anti-slip textures for easy rotation by the operator. A first limiting rod 26 is fixedly installed on the front of the clamping plate 23 by welding. A through hole is provided inside the side plate 22, through which the first limiting rod 26 movably passes. There are two first limiting rods 26, located on either side of the first screw 24, ensuring the stability of the clamping plate 23's sliding motion. The lead angle of the first screw 24 is less than the equivalent friction angle. The specific thread parameters can be designed according to the actual stress conditions to ensure that the first screw 24 has a reliable self-locking function. The outer side of the first screw 24 is coated with grease. Lithium-based grease can be used, which has the characteristics of strong adhesion, anti-leakage, wear resistance, and anti-contamination. During the coating process, it is necessary to ensure that the grease evenly covers the thread surface of the first screw 24, and the thickness is controlled between 0.1-0.2 mm.

[0020] Each individual lithium battery 10 is equipped with a socket 5 and a mounting plate 6 on its upper side. A power supply cable 7 is fixed to the right side of the bracket 4 using screws. The power supply cable 7 uses copper core cable, which has good conductivity and insulation properties. A plug 8 is crimped to the outer end of the power supply cable 7. The plug 8 conforms to national standards and can stably connect to an external power source. The internal wires of the power supply cable 7 are electrically connected to the terminals of multiple sockets 5, and the multiple sockets 5 are connected in parallel. During the connection process, it is necessary to ensure that the wiring is secure to avoid loose connections, and the connection points must be insulated to prevent leakage.

[0021] The stabilizing component 3 includes a stabilizing plate 31, which is made of rubber and has anti-slip texture on the bottom to increase friction with the ground and improve the stability of the bracket. The stabilizing plate 31 is located below the base plate 1. Casters 9 are bolted to the four corners of the bottom of the base plate 1. The casters 9 are equipped with brakes, allowing them to be locked when the bracket does not need to be moved, further improving stability. A lifting plate 32 is welded to the back of the stabilizing plate 31, and a fixing plate 33 is welded to the back of the base plate 1. A second screw 34 is rotatably connected to the top of the lifting plate 32 via a bearing. A threaded hole is provided inside the fixing plate 33, and the second screw 34 is screwed through the threaded hole. A second limiting rod 36 is welded to the top of the lifting plate 32. A through hole is provided inside the fixing plate 33, and the second limiting rod 36 moves through the through hole. There are two second limiting rods 36, located on both sides of the second screw 34. A second knob 35 is fixedly mounted on the top of the second screw 34 by welding. The outer side of the second knob 35 also has anti-slip textures for easy rotation by the operator. The thread lead angle of the second screw 34 is smaller than the equivalent friction angle. Its thread parameters can be designed according to the weight of the stabilizing plate 31 and the required support force to ensure that the second screw 34 has a reliable self-locking function. The outer side of the second screw 34 is also coated with the same grease as the first screw 24, and the coating requirements are the same. Furthermore, all contents not described in detail in this specification are existing technologies known to those skilled in the art, and all electrical components mentioned in this document are powered by external power supply lines.

[0022] Working principle: When using this lithium battery pack charging bracket, first push the bracket to the designated charging position using the casters 9. Then, rotate the second knob 35 to drive the second screw 34 to rotate. Since the second screw 34 is screwed to the fixed plate 33 and the second limit rod 36 limits the lifting plate 32, the rotation of the second screw 34 will drive the lifting plate 32 to move downward, which in turn will drive the stabilizing plate 31 to move downward until the stabilizing plate 31 is in close contact with the ground. At this time, stop rotating the second knob 35. Since the second screw 34 has a self-locking function, the stabilizing plate 31 will maintain its current position, providing stable support for the bracket. At the same time, the brakes of the casters 9 can be locked to further improve stability. Next, place the single lithium battery 10 that needs to be charged on top of the bottom plate 21, so that the back of the single lithium battery 10 is in contact with the front of the side plate 22. Then, turn the first knob 25 to drive the first screw 24 to rotate. The first screw 24 pushes the clamping plate 23 to slide on the bottom plate 21 until the clamping plate 23 is tightly in contact with the front of the single lithium battery 10, thereby clamping and fixing the single lithium battery 10. Since the first screw 24 has a self-locking function, the clamping plate 23 will maintain the clamping force on the single lithium battery 10 to prevent the single lithium battery 10 from shifting during charging. Next, insert the charging plug of the individual lithium battery 10 into the corresponding socket 5, and then insert the plug 8 of the power supply cable 7 into the external power socket. At this time, the external power supply provides power to multiple sockets 5 through the power supply cable 7, and multiple individual lithium batteries 10 begin charging simultaneously. Since the multiple sockets 5 are connected in parallel, each individual lithium battery 10 can obtain a stable voltage and current, ensuring charging efficiency and safety. During the charging process, small tools or accessories of the individual lithium batteries 10 required for charging can be placed on the placement plate 6 for easy access. After the single lithium battery 10 is fully charged, first unplug the plug 8 of the power supply line 7 from the external power socket, then unplug the charging plug of the single lithium battery 10 from the socket 5, then rotate the first knob 25 in the opposite direction to drive the first screw 24 to rotate in the opposite direction, so that the clamp 23 slides away from the single lithium battery 10, thereby releasing the fixation of the single lithium battery 10, and finally remove the single lithium battery 10 from the bottom plate 21. If the bracket needs to be moved to another position, simply turn the second knob 35 in the opposite direction to drive the second screw 34 to rotate in the opposite direction, causing the lifting plate 32 to move upward, which in turn drives the stabilizing plate 31 to move upward until the stabilizing plate 31 separates from the ground. Then release the brake of the universal wheel 9, and the bracket can be moved by pushing the universal wheel 9. By setting the fixing component 2, the individual lithium battery 10 can be stably fixed, preventing it from shifting during charging and improving the stability and safety of charging. By setting the stabilizing component 3, the bracket can be moved and placed stably, improving the convenience of use. By connecting multiple sockets 5 in parallel, each individual lithium battery 10 can obtain a stable current, improving charging efficiency and the lifespan of the lithium battery. The overall structure is reasonably designed, easy to use, and has high practicality and promotional value.
