[0004] However, existing AC charging piles are difficult to install and remove easily, which increases the complexity of installation and reduces the efficiency of maintenance or replacement of charging piles in the later stages. Utility Model Content

[0005] This utility model provides a new type of 7kW AC charging pile, which has the advantages of easy and convenient installation and disassembly, thus solving the problem that existing AC charging piles are difficult to install and disassemble in a convenient manner, which increases the complexity of installation and reduces the maintenance efficiency of later inspection or replacement of charging piles.

[0006] To facilitate convenient installation and disassembly of charging piles, this utility model provides the following technical solution: A novel 7kW AC charging pile includes a cover plate and a base disposed on one side of the cover plate. The base has two sets of inlet pipes at its bottom. It also includes two sets of sockets disposed on both sides of the base. A limiting sleeve is inserted into the interior of each socket. A telescopic assembly is slidably connected inside the limiting sleeve. The telescopic assembly includes a sliding rod, a positioning ring, and a telescopic spring. A connecting piece is disposed on the surface of the limiting sleeve. A support plate is fixedly connected to one end of the connecting piece. Two sets of support assemblies are fixedly connected to one side of the support plate. Each support assembly includes a sliding block, a positioning rod, and a support spring. A support seat is fixedly connected to the surface of the positioning rod. An mounting plate is fixedly connected to one side of the support seat.

[0007] As a preferred embodiment of the present invention, the telescopic component includes a sliding rod slidably connected inside the limiting sleeve, a positioning ring sleeved on the surface of the sliding rod, and a telescopic spring fixedly connected to one side of the positioning ring.

[0008] As a preferred embodiment of the present invention, the support assembly includes a sliding block fixedly connected to one side of the support plate, a positioning rod slidably connected inside the sliding block, and a support spring sleeved at both ends of the positioning rod.

[0009] As a preferred technical solution of this utility model, one end of the limiting sleeve is slidably connected with four sets of balls in a circular array, and the socket has a slot inside that matches the balls.

[0010] As a preferred technical solution of this utility model, one end of the sliding rod is provided with a groove that matches the ball bearing, and one end of the limiting sleeve is fixedly connected with a hook.

[0011] As a preferred embodiment of this utility model, a side plate is snapped onto one side of the bottom of the base, and a support shell is fixedly connected to the inner bottom wall of the base. A leakage protection switch is installed inside the support shell.

[0013] As a preferred embodiment of this utility model, a display screen is snapped onto the inner side of the cover plate, and several sets of control board mounting holes are fixedly connected to the inner wall of the base.

[0014] Compared with the prior art, this utility model provides a new type of 7kW AC charging pile, which has the following beneficial effects:

[0015] 1. This new 7kW AC charging pile, through the setting of the telescopic component, allows for easy installation and removal of the charging pile when the sliding rod is pressed. The sliding rod slides within the limiting sleeve, which in turn moves the positioning ring and compresses the telescopic spring. This causes the telescopic spring to contract under force, and the groove at one end of the sliding rod moves to the ball bearing side, loosening the ball bearing and releasing it from the lock. This, in turn, pulls the hook, causing the limiting sleeve to be pulled out of the socket. This achieves the effect of convenient installation and removal of the charging pile, which not only reduces the complexity of installation but also facilitates later maintenance or replacement of the charging pile, improving maintenance efficiency.

[0016] 2. This new 7kW AC charging pile, through the setting of the support components, when in use, if the user places the charging gun on the gunstock and applies improper force, it will press down on the charging pile, thereby causing the sliding block on the back of the support plate to slide within the positioning rod. This causes the two sets of sliding blocks to deform under force and generate elastic force. In turn, the top support spring pulls the sliding block, and the bottom support spring pushes the sliding block, thereby converting the external force into elastic potential energy and quickly restoring it. This effectively offsets part of the impact force and avoids deformation and damage to the connection structure caused by rigid impacts during long-term use, thus improving the safety of the new 7kW AC charging pile.

[0017] 3. In this new 7kW AC charging pile, the outer shell is secured without latches, and the cover and base are connected by screws; the tempered glass panel is eliminated by setting up the display screen, which reduces the tempered glass assembly process and the risk of damage; the leakage protection switch is placed separately in a detachable area through the side panel, which is convenient for users to connect the wiring.

[0024] 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.

[0025] Please see Figures 1-5 This utility model discloses a novel 7kW AC charging pile, including a cover plate 1 and a base 2 disposed on one side of the cover plate 1. The bottom of the base 2 is provided with two sets of inlet pipes 3. It also includes: two sets of sockets 4 disposed on both sides of the base 2. The sockets 4 are internally connected to limit sleeves 5. The limit sleeves 5 are internally slidably connected to telescopic components 6. The telescopic components 6 include a sliding rod 601, a positioning ring 602 and a telescopic spring 603. A connecting piece 7 is disposed on the surface of the limit sleeve 5. One end of the connecting piece 7 is fixedly connected to a support plate 8. Two sets of support components 9 are fixedly connected to one side of the support plate 8. The support components 9 include a sliding block 901, a positioning rod 902 and a support spring 903. A support seat 10 is fixedly connected to the surface of the positioning rod 902. A mounting plate 11 is fixedly connected to one side of the support seat 10.

[0026] Specifically, the telescopic component 6 includes a sliding rod 601 slidably connected inside the limiting sleeve 5, a positioning ring 602 sleeved on the surface of the sliding rod 601, and a telescopic spring 603 fixedly connected to one side of the positioning ring 602.

[0027] In this embodiment, when it is necessary to disassemble or assemble the charging pile, press the sliding rod 601 so that the sliding rod 601 slides inside the limiting sleeve 5. Then the sliding rod 601 drives the positioning ring 602 to move and squeeze the telescopic spring 603, so that the telescopic spring 603 is compressed. Then the groove at one end of the sliding rod 601 moves to the side of the ball 12, so that the ball 12 loosens and is unlocked. Then the hook 13 is pulled, so that the hook 13 drives the limiting sleeve 5 to be pulled out from the socket 4.

[0028] Specifically, the support component 9 includes a sliding block 901 fixedly connected to one side of the support plate 8. A positioning rod 902 is slidably connected inside the sliding block 901, and a support spring 903 is sleeved at both ends of the positioning rod 902.

[0029] In this embodiment, when the user places the charging gun on the gunstock 17, improper force will press down on the charging pile, which will cause the sliding block 901 on the back of the support plate 8 to slide within the positioning rod 902. This causes the two sets of sliding blocks 901 to deform under force and generate elastic force. Consequently, the top support spring 903 pulls the sliding block 901, and the bottom support spring 903 pushes the sliding block 901.

[0030] Specifically, one end of the limiting sleeve 5 is slidably connected with four sets of balls 12 in a circular array, and the socket 4 has a slot inside that matches the balls 12.

[0031] In this embodiment, the four sets of ball bearings 12 at the end of the limiting sleeve 5 cooperate with the internal slot of the socket 4 to form a multi-point mechanical lock, ensuring that the charging pile maintains a stable connection under vibration or external impact.

[0032] Specifically, one end of the sliding rod 601 has a groove that matches the ball 12, and one end of the limiting sleeve 5 is fixedly connected to a hook 13.

[0033] In this embodiment, the matching design of the end groove of the sliding rod 601 and the ball 12 allows the ball 12 to quickly disengage from the slot during the pressing operation, enabling one-handed unlocking, and the hook 13 facilitates the pulling of the limiting sleeve 5.

[0034] Specifically, a side plate 14 is snapped onto one side of the bottom of the base 2, and a support shell 15 is fixedly connected to the inner bottom wall of the base 2. A leakage protection switch 16 is installed inside the support shell 15.

[0035] In this embodiment, the leakage protection switch 16 built into the support shell 15 has dual protection against overload and short circuit, and the side plate 14 adopts a snap-fit ​​installation, which facilitates later maintenance and repair.

[0036] Specifically, a stock 17 is provided on one side of the base 2, and an emergency stop button 18 is provided on one side of the base 2.

[0037] In this implementation, the stock 17 allows users to hang the gun on the fixed position, reducing the probability of the charging gun being damaged due to falling to the ground, and the emergency stop button 18 serves as an emergency stop button in case of emergency.

[0038] Specifically, the inner side of the cover plate 1 is fitted with a display screen 19, and the inner wall of the base 2 is fixedly connected with several sets of control board mounting holes.

[0039] In this implementation scheme, the display screen 19 supports charging status visualization, and the reserved positions for the control board mounting holes meet the expansion needs of control boards of different specifications.

[0040] The working principle and usage process of this utility model are as follows: When it is necessary to disassemble or assemble the charging pile, press the sliding rod 601, so that the sliding rod 601 slides in the limiting sleeve 5. Then the sliding rod 601 drives the positioning ring 602 to move and squeeze the telescopic spring 603, so that the telescopic spring 603 is compressed by force. Then the groove at one end of the sliding rod 601 moves to the side of the ball 12, so that the ball 12 loosens and releases the lock. Then the pull hook 13 is pulled, so that the pull hook 13 drives the limiting sleeve 5 to be pulled out from the socket 4. When in use, if the person places the charging gun on the gunstock 17 and applies force improperly, it will press down on the charging pile, which will cause the sliding block 901 on the back of the support plate 8 to slide in the positioning rod 902. This causes the two sets of sliding blocks 901 to deform under force and generate elastic force. Then the top support spring 903 pulls the sliding block 901, and the bottom support spring 903 pushes the sliding block 901.

[0041] In summary, this new 7kW AC charging pile, through the telescopic component 6, achieves convenient installation and disassembly, which not only reduces installation complexity but also facilitates later maintenance or replacement, improving maintenance efficiency. Through the support component 9, external forces are converted into elastic potential energy and quickly reset, effectively offsetting some of the impact force and avoiding deformation and damage to the connection structure caused by rigid impacts during long-term use, thus improving the safety of the new 7kW AC charging pile.
