New energy lithium battery PACK assembling and positioning mechanism

Abstract

The utility model relates to the technical field of lithium battery assembly, and discloses a new energy lithium battery PACK assembly positioning mechanism which comprises a lithium battery installation box, heat dissipation channels are arranged on the two sides of the lithium battery installation box, electromagnet blocks are installed on the sides, away from each other, of the inner walls of the heat dissipation channels in an electric connection mode, and water baffles are rotatably installed at the bottoms of the heat dissipation channels. When rainwater adheres to the surface of the photoelectric liquid level sensor when the lithium battery installation box is used outdoors, the photoelectric liquid level sensor disconnects a circuit of the electromagnet block to enable the electromagnet block to lose magnetic force, and therefore attraction force between the electromagnet block and the magnet body disappears. Under the action of gravity, the water baffle is turned over downwards to seal the outlet of the heat dissipation channel, so that rainwater cannot enter the lithium battery mounting box, and the situation that the maintenance cost is increased due to the fact that rainwater easily enters the lithium battery mounting box through the heat dissipation groove in rainy days in the use process is avoided.

Description

Technical Field

[0001] This utility model relates to the field of lithium battery assembly technology, specifically a positioning mechanism for assembling a new energy lithium battery pack. Background Technology

[0002] The new energy lithium battery PACK assembly positioning mechanism refers to the mechanism used to accurately position and fix battery cells or modules during the lithium battery PACK assembly process. It ensures that battery cells or modules can be accurately aligned during the assembly process, thereby ensuring that the assembled battery pack has good performance and safety.

[0003] In the process of realizing this invention, the inventors discovered at least the following problems in the prior art:

[0004] Most existing lithium batteries are used in outdoor vehicles. After installation, in order to ensure that the lithium battery is not damaged due to overheating, heat dissipation grooves need to be set inside the mounting and positioning mechanism. However, during use, if it rains, rainwater can easily enter the positioning mechanism through the heat dissipation grooves, causing water ingress and short circuit of the lithium battery, increasing maintenance costs.

[0005] Therefore, the aforementioned technical problems need to be solved. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a new energy lithium battery PACK assembly and positioning mechanism, which solves the problem that rainwater can easily enter the lithium battery mounting box through the heat dissipation groove during use, causing water ingress and short circuits in the lithium battery, thus increasing maintenance costs.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0008] A new energy lithium battery PACK assembly and positioning mechanism includes a lithium battery mounting box. Heat dissipation channels are provided on both sides of the lithium battery mounting box. An electromagnet block is electrically connected to the side of the inner wall of the heat dissipation channel that is far apart from each other. A water baffle is rotatably mounted at the bottom of the heat dissipation channel. A magnet body is fixedly mounted on the side of the water baffle that is far apart from each other. Photoelectric liquid level sensors, electrically connected to the electromagnet blocks, are fixedly mounted on both sides of the lithium battery mounting box. A groove is formed on the side of the inner wall of the heat dissipation channel that is close to each other.

[0009] Preferably, a support frame is uniformly fixedly installed inside the lithium battery mounting box, and a positioning frame is fixedly installed on both sides of the lithium battery mounting box and in the middle of the support frame.

[0010] Preferably, the lithium battery mounting box has lithium battery bodies evenly installed inside, and positioning rods are fixedly installed on both sides of the lithium battery bodies that are far apart from each other, and the positioning rods and the support frame form a limiting mechanism.

[0011] Preferably, a sealing cover is movably mounted on the top of the lithium battery mounting box, and a sealing ring is provided at the bottom of the sealing cover.

[0012] Preferably, the top of the sealing cover has storage slots on both sides, and a handle is rotatably installed inside the storage slots.

[0013] Preferably, limiting rings are fixedly installed on both sides of the front and rear ends of the lithium battery mounting box, and limiting barbs extending into the limiting rings are fixedly installed on both sides of the front and rear ends of the sealing cover.

[0014] Compared with the prior art, this utility model provides a new energy lithium battery PACK assembly positioning mechanism, which has the following beneficial effects: When rainwater adheres to the surface of the photoelectric liquid level sensor of the lithium battery mounting box during outdoor use, the photoelectric liquid level sensor disconnects the circuit of the electromagnet block, causing the electromagnet block to lose its magnetic force. This causes the attraction between the electromagnet block and the magnet body to disappear. Under the action of gravity, the baffle plate flips downward to seal the outlet of the heat dissipation channel, preventing rainwater from entering the interior of the lithium battery mounting box. This avoids the situation where rainwater can easily enter the interior of the lithium battery mounting box through the heat dissipation channel during use, causing water ingress and short circuit of the lithium battery, thus increasing maintenance costs.

Detailed Implementation

[0023] 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.

[0024] As described in the background section, there are shortcomings in the existing technology. In order to solve the above-mentioned technical problems, this application proposes a new energy lithium battery PACK assembly positioning mechanism.

[0025] Please see Figures 1-7 A new energy lithium battery PACK assembly and positioning mechanism includes a lithium battery mounting box 1. Heat dissipation channels 101 are provided on both sides of the lithium battery mounting box 1. An electromagnet block 102 is electrically connected to the side of the inner wall of the heat dissipation channel 101 that is far apart from each other. A water baffle 103 is rotatably installed at the bottom of the heat dissipation channel 101. A magnet body 104 is fixedly installed on the side of the water baffle 103 that is far apart from each other. Photoelectric liquid level sensors 105 are fixedly installed on both sides of the lithium battery mounting box 1 and electrically connected to the electromagnet block 102. A groove 106 is formed on the side of the inner wall of the heat dissipation channel 101 that is close to each other.

[0026] With the above-described structural design, when the new energy lithium battery PACK assembly and positioning mechanism is used outdoors and encounters rain, if rainwater comes into contact with the photoelectric liquid level sensor 105, the photoelectric liquid level sensor 105 disconnects the connection circuit of the electromagnet block 102, causing the electromagnet block 102 to lose its magnetic force. This causes the attraction between the electromagnet block 102 and the magnet body 104 to disappear. Subsequently, under the action of gravity, the water baffle 103 flips downward, and one end of the water baffle 103 slides into the interior of the groove 106 for a lower limit, preventing the water baffle 103 from rotating out of the heat dissipation channel 101. At this time, the outlet of the heat dissipation channel 101 is sealed, thereby preventing rainwater from entering the interior of the lithium battery mounting box 1 through the heat dissipation channel 101. This solves the problem that if rainwater easily enters the interior of the lithium battery mounting box 1 through the heat dissipation groove during use, causing water ingress and short circuit of the lithium battery, thus increasing maintenance costs.

[0027] Furthermore, support frames 107 are uniformly fixedly installed inside the lithium battery mounting box 1, and positioning frames 108 are fixedly installed on both sides of the lithium battery mounting box 1 and in the middle of the support frames 107. When the lithium battery is installed inside the lithium battery mounting box 1, the support frames 107 and positioning frames 108 separate the lithium battery, thus maintaining a certain distance between each group of lithium batteries, ensuring better heat dissipation, and preventing the lithium battery from easily shaking after being positioned inside the lithium battery mounting box 1, thereby improving the installation stability of the lithium battery.

[0028] Furthermore, lithium battery bodies 2 are evenly installed inside the lithium battery mounting box 1. Positioning rods 201 are fixedly installed on both sides of the lithium battery bodies 2 at opposite ends, and the positioning rods 201 and the support frame 107 form a limiting mechanism. When the lithium battery bodies 2 are installed inside the lithium battery mounting box 1, the positioning rods 201 are positioned between each set of support frames 107 to form a limiting mechanism, thereby making the lithium battery bodies 2 more securely installed.

[0029] Furthermore, a sealing cover 3 is movably installed on the top of the lithium battery mounting box 1, and a sealing ring is provided at the bottom of the sealing cover 3. Storage slots 301 are provided on both sides of the top of the sealing cover 3. A handle 302 is rotatably installed inside the storage slots 301. Limiting rings 303 are fixedly installed on both sides of the front and rear ends of the lithium battery mounting box 1. Limiting barbs 304 extending into the limiting rings 303 are fixedly installed on both sides of the front and rear ends of the sealing cover 3. The limiting hook 304 slides into the limiting ring 303. Since the bottom of the limiting hook 304 is a limiting inverted triangle shape, it forms a limiting position, thereby fixing the sealing cover 3 on the top of the lithium battery installation box 1. At this time, the sealing ring at the bottom of the sealing cover 3 is tightly fitted with the inner wall of the top of the lithium battery installation box 1, preventing external rainwater from entering the interior of the lithium battery installation box 1 and causing water damage to the lithium battery body 2. The operator can easily lift the lithium battery installation box 1 to any position by flipping the handle 302 to a vertical position. After the lithium battery installation box 1 is installed, the handle 302 is flipped into the storage slot 301 for storage, so that the handle 302 will not cause obstruction after the lithium battery installation box 1 is installed inside the equipment.
