Description

Technical Field

[0001] This utility model relates to a shockproof structure, specifically a shockproof structure for welding lithium-ion battery terminals, belonging to the field of lithium-ion battery technology. Background Technology

[0002] With the increasing severity of the energy crisis and global environmental problems, the development and application of new energy sources has become a global trend. Lithium-ion power batteries, which use lithium iron phosphate as the cathode material, are considered the best energy source and are developing rapidly. However, existing lithium-ion batteries, which use welding to connect the cells and terminals, may experience loosening and detachment, posing potential safety hazards during use. In particular, the terminals are prone to loosening when the lithium battery is subjected to vibration and bumps during use. Therefore, anti-vibration welding structures for lithium-ion battery terminals have emerged.

[0003] A search revealed a shockproof structure for welding lithium-ion battery terminals, disclosed in Chinese Patent Publication No. CN218070142U. The structure includes a housing, a rubber pad at the bottom of the housing, a lithium battery body at the top of the rubber pad, two threaded through holes at the top of the housing, a threaded cylinder connected to the threaded through holes, a rubber cylinder inside the threaded cylinder, a welding post inside the rubber cylinder, the bottom of the welding post being welded to the contact point of the lithium battery body, and a terminal post being welded to the top of the welding post.

[0004] While the aforementioned device connects the electrode to the lithium battery body via rubber pads, threaded cylinders, and rubber sleeves, and the rotating threaded cylinder lowers it, thus pressing the welding post down and securing it to the battery body, the rubber sleeves and pads also provide shock absorption, further preventing the welding post from detaching. However, the rubber pads and sleeves gradually lose elasticity with temperature changes and external forces, losing their shock-absorbing protection for the lithium-ion battery body and the welded posts. Timely replacement of the rubber pads and sleeves is necessary, but the current device makes replacement inconvenient, hindering lithium-ion battery maintenance. Therefore, we provide a shock-absorbing structure for lithium-ion battery electrode welding to solve these problems. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides a shock-resistant welding structure for lithium-ion battery terminals, the specific technical solution of which is as follows:

[0006] A shock-absorbing structure for welding lithium-ion battery terminals includes a shock-absorbing mechanism. The shock-absorbing mechanism includes a protective frame, multiple first shock-absorbing blocks, and multiple second shock-absorbing blocks. The protective frame is fixedly connected to multiple plug-in blocks. Each of the multiple first shock-absorbing blocks has a first slot, which engages with the plug-in blocks. A battery body is supported above the multiple first shock-absorbing blocks. The battery body is provided with multiple welding posts, each of the welding posts having a first threaded hole. Each of the multiple second shock-absorbing blocks has a second slot, which has a first through hole, and the second slot engages with the welding post. A cover plate is bolted to the protective frame, and the cover plate has multiple second through holes.

[0007] Preferably, the shock absorption mechanism is provided with multiple wire pressing mechanisms, each wire pressing mechanism including a pole post and a first clamping plate, wherein the pole post has a threaded groove.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The lithium-ion battery electrode welding shockproof structure uses a second shock-absorbing block to press down the welding post, thereby facilitating the fixing of the welding post to the battery body. At the same time, the first and second shock-absorbing blocks can provide shock absorption for the battery body, thus preventing the welding post from detaching from the battery body. By unscrewing the bolts connecting the cover plate and the protective frame, the first and second shock-absorbing blocks can be quickly replaced, achieving the purpose of efficient shock absorption of this device. It also allows for convenient replacement of shock-absorbing components, solving the problem that the rubber shock-absorbing components of the above-mentioned devices gradually lose their shock absorption effect under temperature changes and external forces, and the inconvenience of replacing shock-absorbing components, thus realizing the ease of use of this device.

[0015] 2. This lithium-ion battery electrode welding shockproof structure controls the electrode to pass through the second and first through holes in sequence, and connects the threaded groove with the first threaded hole. Then, it controls the external wire to be wound around the outside of the threaded rod, and controls the second clamping plate to rotate clockwise, so that the second clamping plate and the first clamping plate clamp and fix the external wire, thereby achieving the purpose of convenient wiring of this device. By controlling multiple connecting brackets to support the lithium-ion battery mounting plate and aligning the fourth and fifth through holes with each other, and then controlling the screw to pass through the fourth and fifth through holes in sequence, and connecting the screw with the nut in thread, this device can be quickly fixed and installed, achieving the purpose of rapid installation of this device.

The protective frame 101 is fixedly connected to multiple plug-in blocks 102. Each of the multiple first shock-absorbing blocks 103 has a first slot 104, which engages with the plug-in blocks 102. A battery body 105 is supported above the multiple first shock-absorbing blocks 103. The battery body 105 is provided with multiple welding posts 106, each of which has a first threaded hole 107.

The protective frame 101 is bolted to a cover plate 111, which has multiple second through holes 112.

[0026] The first damping block 103 and the second damping block 108 are preferably made of rubber. When the cover plate 111 is bolted to the protective frame 101, the cover plate 111 supports the second damping block 108. The battery body 105 is inserted into the protective frame 101. The second damping block 108 presses down the welding column 106, which facilitates the fixing of the welding column 106 to the battery body 105. At the same time, the first damping block 103 and the second damping block 108 can provide shock absorption for the battery body 105, thereby preventing the welding column 106 from detaching from the battery body 105. By unbolting the cover plate 111 from the protective frame 101, the first damping block 103 and the second damping block 108 can be quickly replaced, achieving the purpose of efficient shock absorption of this device. It also allows for convenient replacement of the damping components, solving the problem that the rubber damping components of the above-mentioned device gradually lose their shock absorption effect under temperature changes and external forces, and the inconvenience of replacing the damping components. This makes the device easy to use.
