Description

Technical Field

[0001] The utility model relates to the technical field of battery pack cooling, and specifically relates to a quick-connect sealing head for a battery pack water pipe. Background Technique

[0002] The battery pack water pipe generally refers to the pipe in the liquid circulation system for cooling or heating the battery in the battery pack (especially the battery pack in an electric vehicle or an energy storage system). Its main function is to conduct heat through the liquid to keep the battery within a safe and efficient operating temperature range. The battery pack water pipe is usually made of high-temperature resistant and corrosion-resistant materials such as polyethylene, polyurethane or metal materials to ensure safety and durability under high temperature and pressure. The coolant flowing in the pipe in a cycle can be pure water, an aqueous solution added with antifreeze or a special coolant to improve the heat conduction efficiency and prevent freezing. The water pipe needs to be connected to a pump and a radiator, usually including a pump to push the circulation of the coolant, and a radiator (such as a heat sink or a cooler) to dissipate heat to the environment.

[0003] Both the connecting pump and the radiator are provided with connecting pipes (connectors) connected to the water pipe. Most of the existing connections between the water pipe and the connecting pipe (connector) adopt a male-female head structure, and the male head and the female head are connected by threads. To ensure the stability and sealing performance of the male-female head connection, when installing the water pipe, tools such as a wrench are usually required to tighten the connection, which increases the complexity of installation. Especially in the environment where the battery pack is mostly installed inside the chassis of an electric vehicle with limited internal space, this makes the operation of connecting the water pipe more difficult. To solve the above-mentioned problems, a quick-connect sealing head for a battery pack water pipe is provided. Content of the Utility Model

[0004] The purpose of the utility model is to provide a quick-connect sealing head for a battery pack water pipe to solve the problem that most of the existing water pipe sealing heads need tools for operation during installation, and the installation and disassembly are complex and cumbersome as mentioned in the above background technique.

A collar is slidably sleeved on the outer side wall of the pipe head where the side strip is installed;

[0007] The collar is slidably engaged with the upper end of the hook, driving the hook to hook on the clamping block, realizing the quick connection between the two pipe heads.

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Apparently, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1-5 , this embodiment provides a quick-connect sealing head for a battery pack water pipe, including a pipe head 1. Among them, two pipe heads 1 are provided. One pipe head 1 is fixedly connected to one end of the water pipe, and the other pipe head 1 is fixedly connected to a connecting pipe (connector) connecting the pump or radiator. By fixedly connecting the two pipe heads 1, the water pipe can be connected to the pump or radiator.

[0023] As Figure 1 shown, a connector is installed on the pipe head 1. The connector includes a clamping block 2 and a hook 3, and both the clamping block 2 and the hook 3 are provided in four. Among them, the four clamping blocks 2 are evenly arranged in a circular array and connected to the outer side wall of one pipe head 1. Four side strips 31 are fixedly connected to the outer side wall of the other pipe head 1, and the four side strips 31 are evenly arranged in a circular array with the pipe head 1 as the center. As Figure 3 and Figure 5 shown, the hook 3 is composed of a rotating plate and a hook head. The hook head is fixedly connected to the edge of the end face of the rotating plate, and the end of the rotating plate away from the hook head is rotatably connected to the side strip 31, that is, one end of the hook 3 is rotatably connected to one end of the side strip 31. A collar 4 is slidably sleeved on the outer side wall of the pipe head 1 with the side strip 31 installed, and as Figure 1 and Figure 4 shown, the collar 4 is slidably engaged with the outer side wall of the side strip 31. During use, one end of the two pipe heads 1 is aligned and engaged, and the clamping block 2 of the pipe head 1 is aligned with the side strip 31 of the other pipe head 1. By sliding the collar 4, a part of the collar 4 is sleeved on the upper end of the hook 3, driving the hook 3 to rotate and hook onto the clamping block 2. The collar 4 limits the hook 3 to maintain the hooked state between the hook 3 and the clamping block 2, thereby completing the connection of the two pipe heads 1.

[0024] Even if one end of the two pipe heads 1 is tightly fitted, due to process problems, the coolant will flow out from the tiny gap between the pipe heads 1. To ensure the sealing performance of the pipe head 1, a ring groove is opened at one end of the pipe head 1, and a sealing ring 11 is installed in the ring groove. The sealing ring 11 is made of rubber material. By filling the gap between the two pipe heads 1 with the sealing ring 11, the sealing performance of the pipe head 1 is ensured.

[0025] As Figure 3 and Figure 5As shown, both the clamping block 2 and the hook head of the hook 3 adopt a triangular prism structure. When the collar 4 limits the hook 3 and the hook 3 is hooked to the clamping block 2, the inclined surface of the hook 3 exerts pressure on the inclined surface of the clamping block 2, thereby driving the two pipe heads 1 to approach each other, clamping the sealing ring 11, deforming the sealing ring 11, filling the gap between the two pipe heads 1, and ensuring the connection tightness between the two pipe heads 1.

[0026] Since the sealing ring 11 is made of rubber material, due to the self-elastic force of the sealing ring 11, the sealing ring 11 will exert a reverse force on the two pipe heads 1, and this force will be exerted on the hook 3 through the inclined surface of the clamping block 2. After the hook 3 receives the force from the clamping block 2, it will rotate. After the collar 4 is engaged with the hook 3, this force will be converted into a directional acting force on the inner wall of the collar 4, thereby fixing the collar 4 and keeping the collar 4 in position to limit the hook 3.

[0027] However, the battery pack is mostly installed on electric vehicles. Therefore, during the driving of the vehicle, the vibration amplitude is relatively large, which easily causes the collar 4 to slide (the damping of the reverse acting force generated by the hook 3 on the inner wall of the collar 4 is small). To stabilize the position of the collar 4 in limiting the hook 3, a spring 32 is installed inside the side strip 31. As Figure 4 and Figure 5 shown, a chute is provided on the end face of the side strip 31, and the spring 32 is installed in the chute. Four sliding blocks 41 are fixedly connected to the inner side wall of the collar 4, and the four sliding blocks 41 are evenly distributed in a circular array inside the collar 4. The sliding blocks 41 are slidably installed in the chute of the side strip 31. The spring 32 exerts an elastic force on the sliding blocks 41 in the direction towards the clamping block 2. Through the elastic force of the spring 32 and the reverse acting force exerted by the hook 3 on the collar 4, the collar 4 can be further fixed to keep the collar 4 in position to limit the hook 3.

[0028] When the water pipe needs to be disassembled, it is necessary to slide the collar 4 so that the collar 4 slides in the direction away from the clamping block 2. At this time, the spring 32 will be compressed, and the compressed spring 32 has a risk of bending and disengaging from the chute of the side strip 31. To limit the spring 32, a limiting rod 33 is installed in the chute of the side strip 31. Both the spring 32 and the sliding block 41 are sleeved on the limiting rod 33, and the spring 32 is limited by the limiting rod 33 to prevent the spring 32 from bending and disengaging from the chute of the side strip 31.

[0029] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
