The housing module includes a top plate, a base, a front plate, a rear plate, a first side plate, a second side plate, and a support unit. The top plate is mounted on top of the support unit, and the base is mounted on the bottom of the support unit. When using this patent, both the first and second charging gun placement slots are used to hold the charging guns. However, this existing patent lacks a charging gun locking mechanism, making it prone to accidental detachment when vehicles pass by, people touch it, or in windy or vibrating conditions. Accidental contact could lead to electric shock.

[0004] Therefore, there is a need to provide a double-locking waterproof mechanism for the charging pile plug. Utility Model Content

[0005] To overcome the shortcomings of existing patented charging gun-less locking mechanisms, which are prone to accidental detachment and electric shock when touched by vehicles, people, or in windy or vibrating conditions, this utility model provides a double-locking and waterproof mechanism for a charging pile plug. This mechanism uses components such as locking blocks, slip rings, and rubber rings to achieve both locking and waterproofing.

[0006] To address the aforementioned issues, this utility model employs the following technical solution: a double-locking waterproof mechanism for a charging pile plug, comprising a charging pile body, a control panel, a cable connector, a cable, a charging gun, and a plug socket. The control panel is mounted on the charging pile body, a cable connector is provided on the charging pile body, a cable is connected to the cable connector, a charging gun is connected to the cable, a plug socket is provided on the charging pile body, and further comprising a push block, a first elastic element, a toggle block, a guide rod, a locking block, a second elastic element, a connecting plate, a slip ring, and a rubber ring. The charging gun has a sliding groove, within which the push block is slidably disposed, a toggle block is fixedly connected to the push block, and a first elastic element connects the push block and the charging gun. The plug socket has a locking groove, within which two guide rods are fixedly connected, locking blocks are slidably disposed on the two guide rods, and a second elastic element is sleeved on the guide rods. The two ends of the second elastic element are respectively connected to the charging gun and the locking block. A connecting plate is fixedly connected to the toggle block, a slip ring is fixedly connected to the connecting plate, and a rubber ring is provided on the plug socket.

[0007] Further explanation: It also includes a mounting base, a guide sleeve, a limiting block, and a third elastic element. The mounting base is fixedly connected to the charging pile body, and the guide sleeve is fixedly connected to the mounting base. The limiting block is slidably set inside the guide sleeve. Three third elastic elements are connected between the limiting block and the guide sleeve. The charging gun has a limiting groove.

[0008] To further explain, it also includes a rubber sleeve; the cable is fitted with a rubber sleeve.

[0009] To further explain, it also includes signal indicator lights; the charging station itself is equipped with four signal indicator lights.

[0010] To further explain, it also includes an emergency stop button, which is installed on the charging station itself.

[0011] To further explain, it also includes a rubber ring, which is embedded in the connector.

[0012] Compared with the prior art, the present invention has the following technical effects: 1. By inserting the charging gun into the socket, after the charging gun's locking block aligns with the socket's locking groove, the second elastic member rebounds and drives the locking block into the locking groove. The first elastic member then drives the push block to move to the left and lock it below the locking block, thereby locking it in place and preventing the charging gun from detaching from the charging pile body. In addition, the slip ring moves with the connecting plate and the lever block, pressing the rubber ring on the socket, thereby achieving a waterproof effect.

[0013] 2. By pressing the limiting block with the charging gun, the limiting block moves downward along the guide sleeve and presses the third elastic element. The third elastic element rebounds and causes the limiting block to lock into the limiting groove, thus firmly locking the charging gun in the storage position. This, together with the locking block, forms a double locking mechanism, preventing the charging gun from swinging freely or being easily taken away when not in use. This protects the charging gun and keeps the site clean and safe. Attached Figure Description

Detailed Implementation

[0020] The present invention will be further described below with reference to specific embodiments. It should also be noted that, unless otherwise explicitly specified and limited, terms such as "setting," "installing," "connecting," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the present invention based on the specific circumstances.

[0021] Example 1: A double-locking waterproof mechanism for a charging pile plug, see reference. Figures 1-5As shown, the device includes a charging pile body 1, a control panel 2, a cable connector 3, a cable 4, a charging gun 5, and a socket 6. The control panel 2 is bolted to the front of the charging pile body 1. The cable connector 3 is located at the bottom of the charging pile body 1, and the cable 4 is connected to the cable connector 3. The end of the cable 4 is connected to the charging gun 5. The socket 6 is located on the upper right side of the charging pile body 1. The device also includes a push block 8, a first elastic element 9, a toggle block 10, a guide rod 11, a locking block 12, a second elastic element 13, a connecting plate 15, a slip ring 16, and a rubber ring 17. The charging gun 5 has a groove 7, and the push block 8 is slidably mounted in the groove 7. Block 12 contacts push block 8. Push block 8 has a lever 10 welded to its top. Push block 8 is connected to charging gun 5 by a first elastic element 9. The plug-in seat 6 has a slot 14. Two guide rods 11 are fixedly connected in the slide groove 7. The two guide rods 11 are slidably mounted with a lever 12. The guide rods 11 are fitted with a second elastic element 13. The two ends of the second elastic element 13 are connected to the charging gun 5 and the lever 12, respectively. A connecting plate 15 is fixedly connected to the lever 10. A slip ring 16 is fixedly connected to the connecting plate 15. The slip ring 16 is fitted on the head of the charging gun 5. A rubber ring 17 is provided on the plug-in seat 6. The charging gun 5 is located inside the rubber ring 17.

[0022] See Figure 2 and Figure 3 As shown, it also includes a rubber ring 26, which is embedded in the plug socket 6.

[0023] After charging is complete, insert the charging gun 5 into the connector 6. Simultaneously, the connector 6 compresses the locking block 12, causing it to move downwards along the guide rod 11 and compressing the second elastic element 13. As the locking block 12 moves, it also compresses the push block 8 and the lever block 10, causing them to move to the right and compressing the first elastic element 9. Once the locking block 12 aligns with the slot 14 of the connector 6, the second elastic element 13 rebounds, causing the locking block 12 to engage in the slot 14. The first elastic element 9 then moves the push block 8 to the left, locking it below the locking block 12, thus locking it in place and preventing the charging gun 5 from discharging. The charging pile body 1 detaches, and the slip ring 16 moves with the connecting plate 15 and the lever 10, pressing the rubber ring 17 on the plug seat 6 to achieve a waterproof effect. When the charging gun 5 is inserted, its smooth metal gun head will fit tightly with the elastic rubber ring 26 to form an effective radial seal. When the charging gun 5 needs to be removed, the lever 10 is moved to the right and the charging gun 5 is removed. When charging, the charging gun 5 is inserted into the charging port, so that the charging pile body 1 transmits electrical energy to the corresponding equipment through the cable connector 3, the cable 4 and the charging gun 5.

[0024] Example 2: Based on Example 1, refer to Figure 1 and Figure 5As shown, it also includes a mounting base 18, a guide sleeve 19, a limiting block 20, and a third elastic element 21. The mounting base 18 is welded to the lower right side of the charging pile body 1. The guide sleeve 19 is fixedly connected to the right side of the mounting base 18. The limiting block 20 is slidably installed inside the guide sleeve 19. Three third elastic elements 21 are connected between the limiting block 20 and the guide sleeve 19. The charging gun 5 has a limiting groove 22, and the limiting block 20 is inserted into the limiting groove 22.

[0025] When the charging gun 5 is placed back onto the plug socket 6, the charging gun 5 presses against the limiting block 20. The limiting block 20 moves downward along the guide sleeve 19 and presses against the third elastic member 21. After the limiting block 20 aligns with the limiting groove 22 on the charging gun 5, the third elastic member 21 rebounds and causes the limiting block 20 to snap into the limiting groove 22, firmly locking the charging gun 5 in the storage position. This, together with the locking block 12, forms a double locking mechanism, preventing the charging gun 5 from swinging freely or being easily removed when not in use. This protects the charging gun 5 and keeps the site clean and safe.

[0026] See Figure 1 and Figure 2 As shown, it also includes a rubber sleeve 23, which is fitted onto the cable 4.

[0027] The rubber sleeve 23, which is fitted onto the cable 4, is located at the connection points between the cable and the charging gun 5, and between the cable and the charging pile body 1, where bending and friction are likely to occur. It effectively prevents the cable sheath from being damaged due to long-term bending or friction.

[0028] See Figure 1 As shown, it also includes signal indicator lights 24. Four signal indicator lights 24 are evenly spaced on the front side of the upper part of the charging pile body 1.

[0029] The signal indicator light 24 installed on the charging pile body 1 displays the current status of the charging pile through different colors and flashing patterns.

[0030] See Figure 1 As shown, it also includes an emergency stop button 25, which is located on the upper right side of the charging pile body 1.

[0031] In case of an emergency during charging, immediately press the emergency stop button 25. The button will cut off the main power output of the charging station and forcibly stop the charging process to prevent the accident from escalating. It is a crucial passive safety protection device.

[0032] The present application has been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of the present application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of the present application. Therefore, the content of this specification should not be construed as a limitation of the present application.
