[0002] With the rapid progress of new energy technology and the continuous expansion of the electric vehicle market, the popularity and construction speed of charging piles, as the key infrastructure for electric vehicle energy replenishment, are significantly increasing. As one of the core components of the charging pile, the performance and reliability of the plug socket are directly related to the smoothness and safety of the charging process. Therefore, the design and optimization of the plug socket has become the focus of the industry.

[0003] Most traditional charging gun holders adopt an open-cover design. When users charge, they need to manually open the gun cover of the charging gun holder to expose the charging port, and then accurately align and insert the charging gun head into the gun holder to start charging after completing the physical connection. Although this design is easy to operate and relatively low-cost in normal environments, its limitations gradually become apparent when facing complex and changeable charging environments and specific application scenarios.

[0004] Especially in outdoor or adverse weather conditions, such as rainy days, sandstorms, etc., the open-cover gun socket is prone to become a channel for moisture and impurities to enter. Once moisture or other conductive substances enter the inside of the gun socket, it may not only cause charging failures, but also cause safety hazards such as short circuits and electric shocks, seriously threatening the user's personal safety and the normal operation of the device. In addition, frequent opening of the cover will also accelerate the wear of the gun socket components and shorten their service life. Summary of the invention

DETAILED DESCRIPTION

[0017] The present invention is further described in detail below in conjunction with specific embodiments, which are intended to explain the present invention rather than to limit it.

[0018] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0019] A piston gas-sealed gun seat, comprising: Figure 1 and Figure 2 As shown, The gun base body 3, the air bag 8, the piston 7, the connecting rod 6, the spring 2, the movable rod 5 and the fixed rod 1, the joints are sealed with sealant; The spring 2 is arranged inside the fixing rod 1, and the fixing rod 1 is sealed and assembled on the gun holder body 3; The piston gas-sealed gun mount includes a piston 7 plug and a connecting rod 6. The piston 7 plug is used to seal the gas, and the connecting rod 6 is used to push the movable rod 5 to move. The piston 7 is arranged inside the movable rod 5, and one end of the movable rod 5 is inserted inside the fixed rod 1, and the end thereof contacts the spring 2. The fixing rod 1 of the piston gas seal gun mount is used to connect the gun mount and install the spring 2. When the spring 2 is compressed, the elastic potential energy is stored; when the spring 2 is extended, the fixing rod 1 bears the elastic force and remains unchanged.

[0020] like Figure 3 and Figure 4As shown, the other end of the movable rod 5 is inserted into the gun base body 3 and is sealed with the airbag 8 to form an air path, and the connection is sealed with sealant; the airbag 8 is arranged on the gun base body 3 around the part for installing the gun head 9; the movable rod 5 and the connecting rod 6 of the piston air-sealed gun base are assembled, and the piston 7 is placed inside; when the gun head 9 is inserted, the connecting rod 6 is pushed, driving the movable rod 5 to move, achieving the effect of compressing the spring 2; when the gun head 9 is pulled out, the spring 2 releases the elastic force, pushing the movable rod 5 to move, driving the connecting rod 6 to move forward.

[0021] like Fig. 9 As shown, one end of the connecting rod 6 is mounted on the movable rod 5, and one end of the connecting rod 6 is mounted on the inner edge of the gun base body 3 for mounting the gun head 9; the connecting rod 6 is arranged transversely along the direction of the movable rod 5 and is respectively mounted at the four corners of the gun base body 3; like Fig.10 As shown, a piston 7 is placed inside the movable rod 5 of the gun seat, and the position of the piston 7 inside the movable rod 5 can be adjusted to adjust the speed of inflation and return of air.

[0022] The movable rod 5 and the connecting rod 6 of the gun seat are assembled. When the gun head 9 is inserted, the connecting rod 6 receives the thrust of the gun head 9, drives the movable rod 5 to move, thereby causing the airbag 8 to change.

[0023] like Figure 5 and Figure 8 As shown, the piston air-sealed gun seat adopts an airbag 8 sealing form. When the airbag 8 is deployed, it closes the gun head 9 mounting part of the gun seat to achieve a sealed state; when the gun head 9 is inserted into the gun seat, the airbag 8 is rolled up.

[0024] Furthermore, the piston-air-sealed gun seat seal is achieved by using the piston 7 to compress the air, and the expansion and convolution of the airbag 8 complete the sealing effect when the gun seat and the gun head 9 cooperate.

[0025] When the gun head 9 is pulled out, the piston air-sealed gun seat releases the elastic force of the spring 2 to push the piston 7 and the connecting rod 6 to move forward, further filling the airbag 8 with air, so that the airbag 8 is deployed.

[0026] When the gun head 9 is inserted into the piston air-sealed gun seat, the inserted gun head 9 pushes the piston 7 connecting rod 6 assembly, further compressing the spring 2, sucking back the air in the airbag 8, so that the airbag 8 returns to the convolution state.

[0027] like Fig. 9 As shown, the connecting rod 6 is installed on the movable rod 5 by interference fit sealing, and is sealed and connected to the movable rod 5; a mounting hole is provided on the movable rod 5, and the connecting rod 6 is installed in the mounting hole, and the connection is sealed by a sealant; the interior of the connecting rod is a cavity structure, and the piston is installed in the internal cavity of the connecting rod; like Fig.11As shown, the gun seat body 3 is used to install the part of the gun head, which is in the shape of a groove, and a slide groove is arranged around the inner edge of the groove, and the connecting rod 6 is slidably arranged in the slide groove; like Figure 6 and Figure 7 As shown, when the gun head 9 is pulled out, the gun base body 3 releases the elastic force of the spring 2 to push the piston 7 and the connecting rod 6 to move forward, filling the airbag 8 with air, so that the airbag 8 is deployed.

[0028] When the gun head 9 is inserted into the gun seat, the inserted gun head 9 pushes the piston 7 connecting rod 6 assembly, compresses the spring 2, and sucks back the air in the air bag 8, so that the air bag 8 returns to the convolution state.

[0029] The gun base is provided with a boss inside, and a slot is provided on the gun head 9. The gun head 9 is fixed to the gun base through the cooperation of the slot and the concave. The gun base body 3 and the gun head 9 are fixed in a buckle form. The gun base is designed with a boss inside, and the gun head 9 is designed with a slot. When the gun head 9 is inserted into the gun base, the slot is just inserted into the boss.

[0030] The fixing rod 1 is a hollow column structure, one end of which is a closed structure and the other end is an open structure.

[0031] The airbag 8 is made of rubber; the airbag convolution state should ensure that the gun head can be normally inserted into the gun seat; that is, the size of the airbag convolution state should not exceed the size of the gun head, such as Fig.12 The airbag should be deployed to completely cover the gun tip; that is, the size of the airbag should be larger than the gun tip, and they can be spliced ​​together to achieve a sealing effect. Fig.13 shown.

[0032] After the gun head 9 is inserted into the gun seat, the piston 7 and the connecting rod 6 receive the elastic force of the spring 2, so that the gun head 9 can be tightly fixed inside the gun seat without shaking.

[0033] The piston gas-sealed gun holder charging pile, the piston gas-sealed gun holder is installed on the charging pile. The gun holder body 3 is fixed on the charging pile by screws 4.

[0034] The piston air-sealed gun mount can be adapted to gun heads of different shapes, meeting the waterproof and dustproof requirements of the gun mount in extremely bad weather. The piston movement is used for inflation and deflation. When it is not inflated, the gun head is not inserted, which is an uncharged state. When it is inflated, the gun head is inserted into the gun mount, which is a connected state, and charging is performed at this time.

[0035] This patent proposes a piston gas-sealed gun holder. It adopts the method of inflation and deflation, and cooperates with the gun head 9 and the gun holder to meet the dust and water resistance requirements during charging and discharging. The specific implementation method is as follows: When the gun mount is not in use, the piston 7 connecting rod 6 assembly fits the gun mount, at which time the spring 2 is in a compressed state, and the airbag 8 maintains a convolution shape. At this time, the gun mount cooperates with the gun head 9 to ensure that the gun mount is dustproof and waterproof.

[0036] When the gun head 9 is pulled out, the piston 7 connecting rod 6 receives the elastic force of the spring 2, and the piston 7 rod is pushed forward under the elastic force, pushing the air to the airbag 8, opening the airbag 8, and making the airbag 8 in the deployed state.

[0037] Air rushes into the airbags 8, and the four airbags 8 begin to inflate, reaching the maximum state, sealing the portion of the gun seat where the gun head 9 is to be installed; at this time, the gun head 9 is inserted into a load such as a car to start charging.

[0038] When charging is finished, the user inserts the gun holder, pushes the connecting rod 6, overcomes the elastic force, compresses the spring 2, and sucks back the air in the airbag 8, so that the airbag 8 becomes smaller and is in a convolution state.

[0039] The connecting rod 6 moves to the bottom, at which time the gun head 9 is locked on the gun seat, the buckle is locked, and the gun head 9 is inserted into the bottom of the gun seat.

[0040] During the insertion of the gun head 9, the spring 2 is compressed backwards, so that the gun head 9 is tightly inserted in the initial state. At this point, the insertion and extraction of the gun is completed as a cycle.
