Description

Technical Field

[0001] This utility model relates to the field of polymer lithium-ion battery technology, specifically to a shockproof and drop-resistant polymer lithium-ion battery. Background Technology

[0002] Lithium-ion batteries are a type of rechargeable battery that primarily works by the movement of lithium ions between the positive and negative electrodes. Lithium-ion batteries generally use materials containing lithium as electrodes and are representative of modern high-performance batteries. However, due to their high risk, true lithium batteries are rarely used in everyday electronic products.

[0003] Multiple polymer lithium-ion battery packs are connected in series to provide more power. Current polymer lithium-ion battery packs, when in use, such as... Figure 1 As shown, connectors are provided at the bottom and top to connect the polymer lithium-ion battery pack. However, many parts of the polymer lithium-ion battery pack are currently exposed, which means that the polymer lithium-ion battery pack does not have the effect of being drop-proof and shock-proof, making the polymer lithium-ion battery pack easy to be damaged. Utility Model Content

[0004] In order to solve the above problems, the purpose of this utility model is to provide a drop-proof and shock-resistant polymer lithium-ion battery.

[0005] To solve the above technical problems, the present invention adopts the following technical solution: a drop-proof and shock-resistant polymer lithium-ion battery, including a base, a polymer lithium-ion battery pack installed on the upper end of the base, a cover plate installed on the top of the polymer lithium-ion battery pack, and sliding grooves opened at both ends of the upper surface of the base and the lower surface of the cover plate. Mounting brackets are slidably inserted into both ends of the sliding grooves. The mounting brackets are U-shaped in general. A vertically arranged shielding rod is fixedly provided between the mounting brackets located at the same end. A vertically arranged sleeve is provided on the shielding rod, and a rubber pad is fixedly provided on the outer wall of the sleeve.

[0006] Preferably, the rubber pad is located between the outer walls of the sleeve and is specifically provided at both ends, with one end of the rubber pad facing the polymer lithium-ion battery pack and the other end of the rubber pad away from the polymer lithium-ion battery pack; the number of the shielding rods is multiple and distributed at equal intervals between two mounting brackets at adjacent ends.

[0007] Preferably, a U-shaped stop rod is movably inserted into the middle end of both sides of the base and the top cover. The two ends of the stop rod are movably inserted into the sliding groove. The mounting bracket has a stop groove at one end in the sliding groove. A lead screw is threaded into the middle end of the stop rod. The end of the lead screw is rotatably disposed on the side wall of the base and the top cover. A protruding rotating wheel is fixedly provided on the side of the lead screw away from the base and the top cover. A plug rod is fixedly provided at one end of the mounting bracket, and a slot corresponding to the plug rod is provided at the other end of the mounting bracket.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0009] In this invention, the mounting bracket can effectively wrap the polymer lithium-ion battery pack intermittently. The shielding rod on the mounting bracket, together with the rubber pad, enhances the overall structural strength of the battery pack, reduces the deformation of the shell caused by external impact, and achieves the purpose of drop and shock resistance. In addition, the mounting bracket is quick-release type, which takes into account the usage needs of the battery pack in both outdoor and indoor environments. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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] Example: Figure 1-4 As shown, this utility model provides a drop-proof and shock-resistant polymer lithium-ion battery, including a base 1. A polymer lithium-ion battery pack 11 is installed on the upper end of the base 1. The polymer lithium-ion battery pack 11 is composed of polymer lithium-ion battery bags. A cover plate 12 is installed on the top of the polymer lithium-ion battery pack 11. Sliding grooves 2 are opened at both ends of the upper surface of the base 1 and the lower surface of the cover plate 12. Mounting brackets 21 are slidably inserted at both ends of the sliding grooves 2. The mounting brackets 21 are U-shaped in general. A vertically arranged shielding rod 22 is fixedly provided between the mounting brackets 21 located at the same end. A vertically arranged sleeve 23 is provided on the shielding rod 22. A rubber pad 24 is fixedly provided on the outer wall of the sleeve 23.

[0018] The rubber pad 24 is located between the outer walls of the sleeve 23, specifically at both ends. One end of the rubber pad 24 faces the polymer lithium-ion battery pack 11, and the other end of the rubber pad 24 is away from the polymer lithium-ion battery pack 11. This arrangement of the rubber pad 24 allows it to protect the polymer lithium-ion battery pack 11 from external objects or the polymer lithium-ion battery pack 11 when the polymer lithium-ion battery is impacted or dropped to the ground.

[0019] The shielding rods 22 are arranged in multiple equal intervals between two mounting brackets 21 at adjacent ends. This arrangement can easily wrap the polymer lithium-ion battery pack 11 and provide multi-directional protection. Moreover, the equal intervals will not affect the heat dissipation of the polymer lithium-ion battery.

[0020] The base 1 and the top cover have U-shaped stop rods 3 movably inserted at their middle ends. The two ends of the stop rods 3 are movably inserted into the slide grooves 2. The mounting bracket 21 is located in the slide groove 2 and has a stop groove 31 at one end. The middle end of the stop rod 3 is threaded with a lead screw 34. The end of the lead screw 34 is rotatably disposed on the side wall of the base 1 and the top cover. After the mounting bracket 21 is inserted into the slide groove 2, the lead screw 34 is driven to rotate, so that the stop rod 3 threaded on the lead screw 34 can be driven to insert into the stop groove 31 on the mounting bracket 21 in the slide groove 2. This completes the fixed connection between the two mounting brackets 21 and the cover plate 12 and the base 1, so that the mounting bracket 21 is stably disposed on the polymer lithium-ion battery pack 11 for protection.

[0021] The lead screw 34 is fixedly provided with a protruding rotating wheel 35 on the side away from the base 1 and the top cover. The rotating wheel 35 allows the operator to directly drive the lead screw 34 to rotate, improving the convenience of operation.

[0022] One end of the mounting bracket 21 is fixedly provided with a plug rod 32, and the other end of the mounting bracket 21 is provided with a slot 33 corresponding to the plug rod 32. The plug rod 32 and the slot 33 can make a preliminary connection when the two mounting brackets 21 are docked, which improves the stability of the connection for subsequent fixing.

[0023] Working principle: When using, such as Figure 2 As shown, Figure 2 Multiple equally spaced shielding rods 22 are arranged around the base 1 and the cover plate 12. The shielding rods 22 can protect the polymer lithium-ion battery pack 11. When an external object collides with the polymer lithium-ion battery pack 11, the shielding rods 22 can effectively connect to it. At the same time, the shielding rods 22 are provided with sleeves 23, and rubber pads 24 are fixedly installed at both ends of the sleeves 23. Therefore, when the external object is hit or dropped, the flexible rubber pads 24 can effectively resist shock. The rubber pads 24 effectively protect the battery pack and reduce the damage caused by external collisions, thus improving the protection life of the polymer lithium-ion battery pack 11.

[0024] Simultaneously, when the polymer lithium-ion battery pack 11 is fixed in its working position, the rotation of the lead screw 34 by the reverse rotation of the rotating wheel 35 drives the two ends of the threaded stop rod 3 to gradually move away from the polymer lithium-ion battery pack 11. At this time, the stop rod 3 disengages from the stop groove 31 on the mounting bracket 21, thus removing the fixation between the mounting brackets 21. Subsequently, the operator can directly pull out the mounting brackets 21 to allow the polymer lithium-ion battery pack 11 to move out of the mounting bracket. Figure 1 The image shows the normal state, which increases the heat dissipation area to ensure normal use. Conversely, when outdoor use or protection is required, the mounting bracket 21 can be inserted into the slide 2, and the rotating wheel 35 can be rotated to install the mounting bracket 21 onto the polymer lithium-ion battery pack 11, thus protecting the polymer lithium-ion battery pack 11. The operation is convenient.

[0025] All standard parts used in this invention can be purchased from the market, and irregularly shaped parts can be customized according to the description and drawings. The specific connection methods of each part all adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts, and equipment all adopt conventional models in the prior art, and the circuit connections adopt conventional connection methods in the prior art, which will not be described in detail here.

[0026] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
