Description

Technical Field

[0001] This utility model relates to the field of charging guns, specifically to an elastic insulating and vibration-proof structure. Background Technology

[0002] With the rapid development of new energy vehicles, the demand for high-power fast charging is growing rapidly. Among high-power fast charging guns, liquid-cooled charging guns, with their lightweight and high-power characteristics, have gradually come into the public eye. The core principle of high-power liquid-cooled charging guns lies in the fact that the cooling water tank at the power terminals transfers heat from the power terminals to the cooling circuit, which then carries the heat away. However, liquid-cooled guns are frequently subjected to vibration, posing a risk of fastening failure. Therefore, vibration protection of the power terminal cooling water tank is particularly crucial.

[0003] Typically, the power terminal cooling water tank fastening structure of a liquid-cooled charging gun consists of two main parts: the power terminal cooling water tank and the fasteners. In existing liquid-cooled charging guns, the power terminal cooling water tank is directly fastened to the housing with screws. Under harsh working conditions such as vibration, the stress generated is directly applied to the fasteners. If the fasteners loosen, the power terminal cooling water tank will move back, reducing the heat conduction contact area and thus posing a risk of weakened heat conduction performance. Summary of the Invention

[0004] Based on this, the purpose of this utility model is to provide an elastic insulating and vibration-proof structure to solve the technical problem that under harsh working conditions such as vibration, the stress generated is directly applied to the fasteners. If the fasteners loosen, the power terminal cooling water tank will move back, reducing the heat conduction contact area and thus creating a risk of weakened heat conduction performance.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an elastic insulating and vibration-damping structure, including a gun head housing and a power terminal cooling water tank embedded in the gun head housing, wherein an elastic insulating pad matching the power terminal cooling water tank is installed in the gun head housing, and a backstop structure fixed to the gun head housing is sleeved and installed at the other end of the power terminal cooling water tank.

[0006] The present invention is further configured such that the inner wall of the gun head housing is integrally formed in a rectangular array with multiple connecting posts, and the side wall of the connecting posts is provided with screw holes.

[0007] The present invention is further configured such that a power terminal is embedded and fixedly installed in the gun head housing, and the power terminal cooling water tank is isolated from the power terminal through the central cavity of the elastic insulating pad.

[0008] The present invention is further configured such that the outer wall of the gun head housing is fitted with a shell for enclosing the cooling water tank for the protective power terminal and the anti-reverse structure.

[0009] The present invention is further configured such that the anti-reverse structure has protrusions integrally formed in a rectangular array, and a through hole is provided at the center of each of the protrusions.

[0010] The present invention is further configured such that a plurality of fasteners are installed on one side of the anti-reverse structure, and the fasteners are threadedly inserted into the connecting column through the through hole.

[0011] The present invention is further configured such that both ends of the power terminal cooling water tank are equipped with circulation pipes, and both circulation pipes pass through the anti-reverse structure and are connected to the liquid cooling pipes.

[0012] In summary, the present invention has the following beneficial effects: By adding an elastic insulating pad at the front end of the power terminal cooling water tank and an anti-reverse component at the rear end, the insulating performance of the elastic insulating component insulates the power terminal from the power terminal cooling water tank. At the same time, when the fasteners tighten the anti-reverse component, the interference fit of the elastic insulating component provides a certain elastic margin, so that during early vibration conditions, part of the force generated by vibration is transferred to the elastic insulating pad, thereby achieving a certain degree of vibration prevention effect.

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0016] An elastic insulating and vibration-damping structure, such as Figure 1-4As shown, the device includes a gun head housing 1 and a power terminal cooling water tank 3 embedded in the gun head housing 1. An elastic insulating pad 2 matching the power terminal cooling water tank 3 is installed in the gun head housing 1. A backstop structure 4 fixed to the gun head housing 1 is fitted and installed at the other end of the power terminal cooling water tank 3. By adding an elastic insulating pad 2 at the front end of the power terminal cooling water tank 3 and a backstop structure 4 at the rear end, the insulation performance of the elastic insulating pad insulates the power terminal from the power terminal cooling water tank 3. At the same time, when the fastener 5 tightens the backstop structure, the interference fit of the elastic insulating pad provides a certain elastic margin, so that when vibration occurs, part of the force generated by the vibration is transferred to the elastic insulating pad 2, thereby achieving a certain degree of vibration prevention effect.

[0017] The inner wall of the gun head housing 1 is integrally formed in a rectangular array with multiple connecting posts 101. The side walls of the connecting posts 101 are provided with screw holes. Power terminals are embedded and fixedly installed in the gun head housing 1. The power terminal cooling water tank 3 is isolated from the power terminal through the central cavity of the elastic insulating pad 2. The outer wall of the gun head housing 1 is equipped with a shell for wrapping and protecting the power terminal cooling water tank 3 and the anti-reverse structure 4. The shell is the charging gun body connected to the gun head housing 1.

[0018] Furthermore, the anti-reverse structure 4 has a rectangular array of integrally formed protrusions, and each of the protrusions has a through hole 401 at its center. The tail end of the anti-reverse structure 4 is fitted with multiple fasteners 5, which are threaded through the through holes 401 and fastened in the connecting post 101. Both ends of the power terminal cooling water tank 3 are fitted with circulation pipes, and both circulation pipes pass through the anti-reverse structure 4 and are connected to the liquid cooling pipes. The liquid cooling pipes use cooling water to circulate in the power terminal cooling water tank 3, which is existing technology and will not be described in detail here.

[0019] The working principle of this utility model is as follows: By adding an elastic insulating pad 2 at the front end of the power terminal cooling water tank 3 and a backstop at the rear end, the insulating performance of the elastic insulating pad insulates the power terminal from the power terminal cooling water tank 3. At the same time, when the fastener 5 presses the backstop, the interference fit of the elastic insulating pad provides a certain elastic margin, so that during early vibration conditions, part of the force generated by vibration is transferred to the elastic insulating pad 2, thereby achieving a certain degree of vibration prevention effect.
