Charging gun idle anti-drop structure for charging pile

Abstract

This utility model relates to the field of charging pile technology, specifically to a charging gun anti-detachment structure for charging piles. It includes a base, a charging body mounted on one side of the base, and an anti-detachment component installed between the charging body and the charging gun. The anti-detachment component prevents the charging gun from falling off. Compared to existing technologies, this application, by setting the anti-detachment component, allows for manual pressing of the trigger handle after the charging gun is fully inserted, aligning the latch with the lock hole of the locking block. Upon release, a pressure spring pushes the latch to automatically engage in the lock hole, completing the lock. At this time, the arc-shaped support surface of the support block continuously abuts against the charging gun, providing auxiliary fixation. Furthermore, under external force, the weight of the charging gun is converted into a radial locking force of the latch, achieving self-reinforcing anti-detachment. To unlock, both sides must be pressed simultaneously. The trigger rod retracts the latch and the support block resets, allowing the charging gun to be safely removed.

Description

Technical Field

[0001] This utility model relates to the field of charging pile technology, and in particular to a structure for preventing the charging gun from detaching when idle in a charging pile. Background Technology

[0002] With the booming development of the new energy vehicle industry, the number of charging piles and their usage frequency are constantly increasing as an important supporting infrastructure for electric vehicles. Charging piles provide electric power to electric vehicles through charging guns. As a key component connecting charging piles and electric vehicles, the performance and reliability of the charging gun directly affect the safety and efficiency of the charging process.

[0003] When not in use, existing charging guns are typically simply placed on a bracket on one side of the charging station. When the charging station is subjected to external impact or shaking, the charging gun can easily fall off the bracket. For example, in some public parking lots, where there is frequent movement of people and vehicles, the charging station may be accidentally bumped, causing the charging gun to fall. This could not only damage the charging gun but also pose a safety hazard to surrounding people and equipment. Utility Model Content

[0004] In view of this, the purpose of this utility model is to propose an anti-detachment structure for charging guns in charging piles when idle, so as to solve the problem that existing charging guns are prone to detachment due to external force when idle.

[0005] To achieve the above objectives, this utility model provides an idle anti-detachment structure for a charging gun in a charging pile, comprising: a base, a charging body mounted on one side of the base, a charging gun mounted on one side of the charging body, a charging cable mounted on one side of the charging gun, the other side of the charging cable mounted on one side of the charging body, and an anti-detachment component installed between the charging body and the charging gun, the anti-detachment component being used to prevent the charging gun from falling off.

[0006] Preferably, the anti-detachment component includes a connecting seat fixedly installed on one side of the charging body, a plurality of locking tongues slidably installed in the connecting seat, and locking blocks fixedly installed on both sides of the charging gun. The locking blocks are provided with locking holes, and the locking holes are adapted to the locking tongues.

[0007] Preferably, a cover is installed on one side of the connecting seat, and a plurality of second sliding grooves are provided on the cover. A plurality of third sliding grooves are provided inside the connecting seat, and the third sliding grooves correspond one-to-one with the second sliding grooves. A receiving cavity is provided inside the connecting seat, and two trigger grips are slidably installed in the receiving cavity. A slider is fixedly installed on one side of each trigger grip. The slider passes through the third sliding groove and the second sliding groove in sequence and extends therefrom. A pressure spring is fixedly installed between the two sliders.

[0008] Preferably, a second trigger groove is provided in the connecting seat, and a trigger block is slidably installed in the second trigger groove. The two sides of the trigger block abut against one side of the two trigger grips, respectively.

[0009] Preferably, a first trigger groove is provided in the connecting seat, a support block is slidably installed in the first trigger groove, and a connecting block is fixedly installed on the support block near the box cover, with one side of the connecting block abutting against one side of the trigger block.

[0010] Preferably, some parts of the trigger grip are fixedly mounted with trigger rods, and the locking tongue is fixedly connected to the trigger rods.

[0011] Preferably, the support block is arc-shaped and is adapted to one side of the charging gun.

[0012] Preferably, one side of the connecting block is inclined, and one side of the trigger block is also inclined, with the inclined surfaces of the connecting block and the trigger block abutting each other.

[0013] Preferably, a charging port is provided in the middle of the connecting seat, the charging port is adapted to the charging gun, and sliding grooves are symmetrically provided on both sides of the charging port, and the locking block is slidably installed in the sliding grooves.

[0014] The beneficial effects of this utility model are:

[0015] 1. This type of charging station features an anti-disengagement structure for the charging gun. By incorporating an anti-disengagement component, when the charging gun is inserted into the charging port of the connector, the locking block pushes the support block along the sliding groove. The inclined surfaces of the connecting block and the trigger block engage, driving the trigger handles on both sides to overcome the spring force of the pressure spring and open outwards. After full insertion, manually pressing the trigger handle aligns the latch with the lock hole of the locking block. Releasing the handle pushes the latch into the lock hole automatically, completing the locking process. At this time, the arc-shaped support surface of the support block continuously supports the charging gun, providing auxiliary fixation. Furthermore, when external force is applied, the weight of the charging gun is converted into a radial locking force on the latch, achieving self-reinforcing anti-disengagement. To unlock, both trigger handles must be pressed simultaneously. The trigger rod retracts the latch and links the support block to reset, allowing the charging gun to be safely removed. The entire process achieves anti-disengagement through mechanical linkage. The inclined transmission mechanism ensures smooth and reliable operation, and the combined effect of spring force and gravity forms multiple safety features.

[0016] 2. This type of charging pile uses an idle anti-disengagement structure for the charging gun. When the charging gun is pulled down by an external force, the locking block drives the lock hole to generate an oblique force on the lock tongue. This force can be decomposed into a horizontal component force to make the lock tongue go deeper into the lock hole and a vertical component force. At the same time, the arc-shaped support surface of the support block converts the weight of the charging gun into radial pressure. Through the inclined surface cooperation of the connecting block and the trigger block, the pressure is converted into the lateral locking force of the lock tongue. The pressure spring continuously provides pre-tightening force. The synergistic effect of the three makes the greater the external force, the tighter the engagement between the lock tongue and the lock hole. Attached Figure Description

[0028] like Figures 1 to 6 As shown, the charging gun idle anti-detachment structure for charging pile includes: a base 1, a charging body 4 installed on one side of the base 1, a charging gun 2 installed on one side of the charging body 4, a charging cable 3 installed on one side of the charging gun 2, the other side of the charging cable 3 installed on one side of the charging body 4, and an anti-detachment component installed between the charging body 4 and the charging gun 2 to prevent the charging gun 2 from falling off.

[0029] When the charging gun 2 is not in use, it is securely fixed to one side of the charging body 4 by the anti-detachment component, preventing it from accidentally falling off. The anti-detachment component is tightly connected to the charging gun 2 by a mechanical buckle, ensuring that the charging gun 2 will not detach from the base 1 due to external force or vibration when idle. One end of the charging cable 3 is connected to the charging gun 2, and the other end is connected to the charging body 4, forming a complete charging circuit. When the charging gun 2 needs to be used, the user only needs to operate the anti-detachment component to remove the charging gun 2 from the anti-detachment component for charging. After use, the charging gun 2 can be reinserted into the anti-detachment component to restore its fixed state. The whole process requires no additional operation, which not only ensures the safe storage of the charging gun 2 but also improves the convenience of use.

[0030] like Figures 2 to 6As shown, the anti-detachment component includes a connecting seat 5 fixedly installed on one side of the charging body 4. Several locking tongues 19 are slidably installed inside the connecting seat 5. Locking blocks 22 are fixedly installed on both symmetrical sides of the charging gun 2. Locking holes 23 are opened on the locking blocks 22, and the locking holes 23 are adapted to the locking tongues 19. A cover 7 is installed on one side of the connecting seat 5. Several second sliding grooves 12 are opened on the cover 7. Several third sliding grooves 14 are opened inside the connecting seat 5, and the third sliding grooves 14 correspond one-to-one with the second sliding grooves 12. A receiving cavity 13 is opened inside the connecting seat 5. Two trigger grips 6 are slidably installed inside the receiving cavity 13. A slider 8 is fixedly installed on one side of each trigger grip 6. The slider 8 passes through the third sliding groove 14 and the second sliding groove 12 sequentially and extends outwards. A pressure spring 9 is fixedly installed between the two sliders 8. A second trigger groove 16 is opened inside the connecting seat 5, and a trigger block 21 is slidably installed inside the second trigger groove 16. The two sides of the trigger block 21 abut against one side of each of the two trigger grips 6; a first trigger groove 15 is provided in the connecting seat 5, and a support block 11 is slidably installed in the first trigger groove 15. A connecting block 20 is fixedly installed on the support block 11 near the box cover 7, and one side of the connecting block 20 abuts against one side of the trigger block 21; a trigger rod 18 is fixedly installed on some of the trigger grips 6, and the locking tongue 19 is fixedly connected to the trigger rod 18; the support block 11 is arc-shaped and is adapted to one side of the charging gun 2; one side of the connecting block 20 is inclined, and one side of the trigger block 21 is also inclined, and the inclined surfaces of the connecting block 20 and the trigger block 21 abut against each other; a charging port 17 is provided in the middle of the connecting seat 5, and the charging port 17 is adapted to the charging gun 2. Sliding grooves 24 are symmetrically provided on both sides of the charging port 17, and the locking block 22 is slidably installed in the sliding grooves 24;

[0031] When the charging gun 2 is not inserted, the two trigger handles 6 remain separated under the force of the pressure spring 9, and the support block 11 is located in the first trigger groove 15. When the charging gun 2 is inserted, first push the charging gun 2 completely into the charging port 17 so that the locking block 22 slides into the connecting seat 5 along the sliding groove 24. At this time, manually press the two trigger handles 6 inward so that they move towards each other against the force of the pressure spring 9. At the same time, the trigger handles 6 squeeze the trigger block 21 to move along the second trigger groove 16. The trigger block 21 pushes the connecting block 20 through the inclined contact surface, causing the support block 11 to move outward. Then, slightly pull the charging gun 2 outward to make the locking block... The lock hole 23 of 22 is aligned with the bolt 19. After releasing the trigger handle 6, the rebound force of the pressure spring 9 causes the bolt 19 to insert into the lock hole 23 to complete the locking. During this process, the arc-shaped surface of the support block 11 always fits against the charging gun 2 to provide support. When an external force is applied, the gravity of the charging gun 2 and the pressure spring 9 will make the bolt 19 and the lock hole 23 lock more tightly. When unlocking is required, press the two trigger handles 6 again to make the bolt 19 exit the lock hole 23, and the charging gun 2 can be removed. The entire mechanism maintains a stable locking state through the elasticity of the pressure spring 9, and the inclined contact surface realizes the effective transmission of force to ensure reliable anti-disengagement function.
