Description

Technical Field

[0001] This utility model relates to the field of charging pile technology, specifically a safe electric vehicle charging pile. Background Technology

[0002] Charging piles function similarly to gas pumps at gas stations. They can be fixed to the ground or walls and installed in public buildings (public buildings, shopping malls, public parking lots, etc.) and residential parking lots or charging stations. They can charge various models of electric vehicles according to different voltage levels. The input end of the charging pile is directly connected to the AC power grid, and the output end is equipped with a charging plug for charging electric vehicles. Charging piles generally provide two charging methods: regular charging and fast charging. People can use a specific charging card to swipe on the human-machine interface provided by the charging pile to perform operations such as selecting the charging method, charging time, and printing fee data.

[0003] Based on the above, the inventors have discovered the following problems: Most current charging guns use simple hooks or open suspension structures, without a stable locking mechanism designed for complex outdoor scenarios. This makes the charging guns prone to falling off. After falling off, the charging gun may not only be damaged by impact with the ground, leading to increased maintenance costs, but also expose the charging interface, making it easy for rainwater and dust to enter and cause short circuits and leakage. If the fallen charging gun and cable trip pedestrians or are run over by vehicles, it may also cause personal injury or secondary damage to the equipment.

[0004] Therefore, in view of this, we will study and improve the existing structure and its shortcomings to provide a safe electric vehicle charging station, in order to achieve a more practical value. Utility Model Content

[0005] The purpose of this invention is to provide a safe electric vehicle charging station to solve the problems mentioned in the background art.

[0006] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0007] A safe electric vehicle charging station includes a charging station body and a locking assembly. The charging station body includes a charging station housing, and a charging gun is provided on one side of the charging station housing. The locking assembly includes a U-shaped frame, which is disposed outside the charging gun. The inner wall of the U-shaped frame is in contact with the outer wall of the charging gun located between the handle and the charging head. An elastic clip is provided inside the U-shaped frame. The bottom end of the elastic clip is arc-shaped and presses against the outer wall of the charging gun located between the handle and the charging head. Slots are provided on both sides of the inner wall of the U-shaped frame, and locking blocks are installed at both ends of the elastic clip, with the locking blocks inserted into the slots.

[0008] Furthermore, the elastic clip is V-shaped and is made of spring steel.

[0009] The beneficial effects of adopting the above-mentioned further solution are that the V-shaped elastic clip can generate a continuous clamping force through its own deformation when subjected to force, forming a stable elastic pressure on the charging gun and ensuring that the charging gun does not shake in the U-shaped frame; the spring steel material (such as 65Mn) has a high elastic limit and fatigue strength, and is not prone to plastic deformation after repeated clamping (taking and taking off the charging gun), and can maintain the clamping force for a long time. At the same time, it has good rust resistance, is suitable for outdoor humid environments, and extends the service life of the locking components.

[0010] Furthermore, the diameter of the charging gun at both the handle and the charging head is larger than the inner diameter of the U-shaped frame. A cable is connected to the handle of the charging gun, and the cable is connected to a connector on the outer wall of the charging pile housing.

[0011] The beneficial effect of adopting the above-mentioned further solution is that the diameter of the handle and the charging head is larger than the inner diameter of the U-shaped frame, forming a limit at both ends. When the elastic clip holds the charging gun, the handle and the charging head form physical barriers from both ends of the U-shaped frame to prevent the charging gun from slipping off along the axial direction (front and back direction). With the elastic clip holding, "bidirectional fixation" is achieved, completely avoiding the charging gun from falling off due to external force collision or its own weight.

[0012] Furthermore, the thickness of the U-shaped frame is consistent with the length of the charging gun located between the handle and the charging head.

[0013] The beneficial effect of adopting the above-mentioned further solution is that the thickness of the U-shaped frame matches the length of the clamping section of the charging gun, which allows the charging gun to be completely wrapped by the U-shaped frame in the clamping area, avoiding uneven force caused by local suspension.

[0014] Furthermore, the charging gun has a first sealing gasket installed on the outer wall of the charging head, and the outer wall of the charging pile housing has a sealing seat installed. The sealing seat has a second sealing gasket fitted on the outer wall of the end of the charging head near the charging gun, and the first sealing gasket and the second sealing gasket are in contact with each other.

[0015] The beneficial effect of adopting the above-mentioned further solution is that the first sealing gasket and the second sealing gasket (usually made of silicone rubber) form a double sealing structure after being bonded together, which can effectively prevent rainwater, dust and foreign objects from entering the charging gun interface and the sealing seat, and avoid electrical faults such as short circuits and poor contact caused by moisture or impurities.

[0016] Furthermore, the charging pile housing has a support plate installed on the outer wall below the charging gun, a guide plate is installed at one end of the support plate, the guide plate is tilted upward at the end away from the support plate, and a wire hole is opened at the end of the guide plate away from the support plate.

[0017] The beneficial effects of adopting the above-mentioned further solutions are that the support plate and guide plate can support the charging gun cable, preventing the cable from sag due to its own weight and causing stress and pulling at the joint with the charging pile housing (reducing the risk of cable breakage); the upward-curving design of the guide plate can guide the cable to bend naturally and avoid right-angle bends (preventing internal copper wire breakage); the cable hole can limit the cable to prevent vehicles from running over it or people from stepping on it, while keeping the cable neatly stored and reducing the risk of tripping.

[0018] Furthermore, the charging pile housing is composed of an outer layer, a middle layer, and an inner layer. The outer layer is an ABS plastic sheet, the middle layer is a honeycomb panel, and the inner layer is a stainless steel sheet. The outer layer is 5mm thick, the middle layer is 10mm thick, and the inner layer is 3mm thick.

[0019] The beneficial effects of adopting the above-mentioned further solutions are that the outer 5mm ABS sheet provides impact resistance and weather resistance, protecting the shell from external collisions and environmental corrosion; the middle 10mm honeycomb sheet (such as aluminum honeycomb) disperses the impact force through the honeycomb structure, greatly improving the shell's compression resistance and cushioning performance, while reducing the overall weight; the inner 3mm stainless steel sheet enhances the shell's structural strength, prevents internal electrical components from being damaged by compression due to shell deformation, and has fireproof and puncture-proof properties.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows: The V-shaped elastic clip of this safe electric vehicle charging pile can generate a continuous clamping force through its own deformation when subjected to force, forming a stable elastic pressure on the charging gun. The diameter of the handle and the charging head is larger than the inner diameter of the U-shaped frame, forming a limit at both ends. When the elastic clip clamps the charging gun, the handle and the charging head form physical barriers from both ends of the U-shaped frame, preventing the charging gun from slipping off along the axial direction (front and back direction). With the clamping of the elastic clip, "bidirectional fixation" is achieved, completely avoiding the charging gun from falling off due to external force collision or its own weight. When it is necessary to remove the charging gun for charging, the elastic clip is squeezed towards the center, causing the elastic clip to deform and the card block to separate from the card slot. Then, after the elastic clip is removed as a whole, the charging gun is pulled upward to move it out of the U-shaped frame, and then the cable is placed on the guide plate wire hole.

[0028] Please see Figures 1-5 This utility model provides a technical solution: a safe electric vehicle charging pile, including a charging pile body 1 and a locking assembly 2. The charging pile body 1 includes a charging pile housing 11, and a charging gun 16 is provided on one side of the charging pile housing 11. The locking assembly 2 includes a U-shaped frame 21, which is disposed outside the charging gun 16.

An elastic clip 22 is provided inside the U-shaped frame 21. The bottom end of the elastic clip 22 is arc-shaped. The U-shaped frame 21 has slots 24 on both sides of its inner wall, and the elastic clip 22 has blocks 23 at both ends. The blocks 23 are inserted into the slots 24. The elastic clip 22 is V-shaped and made of spring steel. When subjected to force, the V-shaped elastic clip 22 can generate a continuous clamping force through its own deformation, forming a stable elastic pressure on the charging gun 16. The diameter of the handle and the charging head is larger than the inner diameter of the U-shaped frame 21, forming a limit at both ends.

[0029] 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.

[0030] Please see Figures 1-5 This utility model provides a technical solution: the diameter of the charging gun 16 at the handle and the charging head is larger than the inner diameter of the U-shaped frame 21. A cable 15 is connected to the handle of the charging gun 16, and the cable 15 is connected to the connector on the outer wall of the charging pile housing 11. The thickness of the U-shaped frame 21 is the same as the length of the charging gun 16 between the handle and the charging head. A first sealing gasket 17 is installed on the outer wall of the charging gun 16 at the charging head. A sealing seat 18 is installed on the outer wall of the charging pile housing 11. A second sealing gasket 19 is fitted on the outer wall of the sealing seat 18 at the end near the charging head of the charging gun 16. The first sealing gasket 17 and the second sealing gasket 19 are in close contact. A support plate 12 is installed on the outer wall of the charging pile housing 11 below the charging gun 16. A guide plate 13 is installed on one end of the support plate 12. The guide plate 13 is curved upward at the end away from the support plate 12. A wire hole 14 is opened on the end of the guide plate 13 away from the support plate 12. The charging pile housing 11 is composed of an outer layer, a middle layer and an inner layer. The outer layer is made of ABS plastic sheet 1101, the middle layer is honeycomb plate 1103, and the inner layer is stainless steel plate 1102. The outer layer is 5mm thick, the middle layer is 10mm thick, and the inner layer is 3mm thick. The diameter of the handle and charging head is larger than the inner diameter of the U-shaped frame 21, forming a limit at both ends. The first sealing gasket 17 and the second sealing gasket 19 are usually made of silicone rubber and are bonded together to form a double sealing structure, which can effectively prevent rainwater, dust, and foreign objects from entering the charging gun 16 interface and the sealing seat 18, avoiding electrical faults such as short circuits and poor contact caused by moisture or impurities. The 5mm ABS sheet on the outer layer provides impact resistance and weather resistance, protecting the shell from external collisions and environmental corrosion. The 10mm honeycomb plate 1103 in the middle layer disperses the impact force through the honeycomb structure, greatly improving the shell's compression resistance and cushioning performance, while reducing the overall weight. The 3mm stainless steel plate 1102 in the inner layer enhances the structural strength of the shell, prevents the internal electrical components from being damaged by compression due to shell deformation, and has fireproof and puncture-proof properties.

[0031] Specifically, the working principle of this type of safe electric vehicle charging station is as follows: When in use, the elastic clip 22 can generate a continuous clamping force through its own deformation when subjected to force, forming a stable elastic pressure on the charging gun 16. The diameter of the handle and the charging head is larger than the inner diameter of the U-shaped frame 21, forming a limit at both ends. When the elastic clip 22 clamps the charging gun 16, the handle and the charging head form physical barriers from both ends of the U-shaped frame 21, preventing the charging gun 16 from slipping off in the axial direction, and completely avoiding the charging gun 16 from falling off due to external impact or its own weight. When it is necessary to remove the charging gun 16 for charging, the elastic clip 22 is squeezed towards the center, causing the elastic clip 22 to deform and the locking block 23 to separate from the locking slot 24. Then, the elastic clip 22 is removed as a whole, and the charging gun 16 is pulled upward to move it out of the U-shaped frame 21. Then, the cable 15 is placed on the wire hole 14 of the guide plate 13.
