Specific embodiments

[0023] The present invention will be further described below with reference to the accompanying drawings.

[0024] A charging gun return locking device for a charging pile, used to lock the charging gun of the charging pile, includes: socket 1, microswitch 2 and electronic lock 3. The socket 1 is fixed on the charging pile, the microswitch 2 and the electronic lock 3 are respectively fixed on the outside of the socket 1. There is a socket opening 1-1 in the socket 1 for inserting the charging gun into the socket opening 1-1 of the socket 1. At least part of the microswitch 2 extends into the socket opening 1-1. When the charging gun 1 is inserted into the socket opening 1-1, the charging gun 1 drives the trigger head on the microswitch 2 to move, thereby triggering the microswitch 2. The electronic lock 3 is connected to the microswitch 2, and the lock core of the electronic lock 3 is driven by the microswitch 2 to extend into the socket opening 1-1, so as to lock the charging gun in the socket opening 1-1.

[0025] In this embodiment, the microswitch 2 has at least one trigger head 2-1 that can reciprocate. The trigger head 2-1 extends into the socket opening 1-1, so as to drive the trigger head to move relatively through the charging gun, thereby triggering the microswitch 2 to work; the electronic lock 3 has at least one locking tongue that can extend and retract relative to the socket 1. By sending a control signal from the microswitch 2 to the electronic lock 3, the electronic lock 3 works, so that the locking tongue extends into the socket opening 1-1, thereby locking the charging gun in the socket opening 1-1.

[0026] An installation assembly is sleeved outside the microswitch 2. There is a support column 1-2 on the socket 1. The installation assembly is fixed on the support column 1-2 by screws, so as to install the microswitch 2 on the outside of the socket 1. During the use of the microswitch 2, the actual moving stroke of the trigger head is greater than the rated contraction stroke of the trigger head on the microswitch 2. When the microswitch 2 and the socket 1 are rigidly connected, it is easy to damage the microswitch 2, which is not conducive to improving the service life of the locking device.

[0027] To improve the service life of the locking device, the installation component includes an installation bracket 4 and an installation sleeve 5 slidably installed in the installation bracket 4. The installation sleeve 5 is sleeved outside the microswitch 2, and the microswitch 2 is fixed on the outer wall of the socket 1 through the installation bracket 4. A buffer 6 for providing a force towards the socket 1 to the installation sleeve 5 is provided on the installation sleeve 5 to ensure that the microswitch 2 abuts against the socket 1, facilitating the triggering of the microswitch 2 by the charging gun. At the same time, when the retraction stroke of the trigger head of the microswitch 2 is too large, the buffer 6 deforms, causing the microswitch 2 to move in a direction away from the socket 1, thereby preventing the microswitch 2 from being damaged.

[0028] The installation bracket 4 includes a fixed plate 4-2 and a movable plate 4-3. The fixed plate 4-2 is fixed on the support column 1-2 by screws. The movable plate 4-3 is sleeved outside the support column 1-2, and the movable plate 4-3 can move relative to the fixed plate 4-2. By changing the distance between the movable plate 4-3 and the fixed plate 4-2, the positional relationship between the microswitch 2 and the socket 1 is changed, thereby preventing the microswitch 2 from being damaged.

[0029] An installation groove 4-1 is provided in the fixed plate 4-2. The installation sleeve 5 is inserted into the installation groove 4-1. Preferably, there is a clearance fit between the installation sleeve 5 and the installation groove 4-1. Screw grooves 4-6 are provided on both sides of the installation groove 4-1, and the screws are connected to the support column 1-2 through the screw grooves 4-6. A clamping groove 4-4 is provided on the movable plate 4-3, and the installation sleeve 5 is inserted into the clamping groove 4-4. Similarly, there is a clearance fit between the installation sleeve 5 and the clamping groove 4-4. Guide grooves 4-7 are provided on both sides of the clamping groove 4-4, and the movable plate 4-3 is slidably connected to the support column 1-2 through the guide grooves 4-7.

[0030] A guide groove 4-8 is also connected to the side wall of the installation groove 4-1. Correspondingly, an abutting groove 4-9 is connected to the side wall of the clamping groove 4-4. The buffer 6 is respectively connected to the guide groove 4-8 and the abutting groove 4-9. The buffer 6 is guided by the guide groove 4-8 to facilitate applying a force towards the socket 1 to the guide member 6, thereby transmitting the above force to the microswitch 2, so that the microswitch 2 always abuts against the socket 1.

[0031] On the side wall of the microswitch 2, at least two buffer members 6 are provided. The buffer member 6 includes a guide plate 6-3 and an abutting plate 6-4 that are inclined to each other. The length direction of the guide plate 6-3 is inclined relative to the axis of the microswitch 2, and the distance between the tops of adjacent guide plates 6-3 is greater than the diameter of the microswitch 2. A guide surface 6-1 is provided on the guide plate 6-3, and the guide surface 6-1 abuts against the inner wall of the guide groove 4-8 to provide a force towards the socket 1 to the mounting sleeve 5 through the cooperation of the guide surface 6-1 and the mounting groove 4-1. A support surface 6-2 is provided on the abutting plate 6-4, and a part of the support surface 6-2 extends into the abutting groove 4-9 of the clamping groove 4-4. And a plurality of stepped surfaces are provided on the support surface 6-2. When the end surface of the movable plate 4-3 abuts against different stepped surfaces, the relative positions of the movable plate 4-3 and the abutting plate 6-4 change, thereby increasing the deformation distance of the microswitch 2.

[0032] The steps for the microswitch 2 to move relative to the mounting assembly are as follows: When the actual movement amount of the trigger head 2-1 of the microswitch 2 is greater than the rated stroke of the trigger head 2-1, the trigger head 2-1 drives the microswitch 2 to move in a direction away from the socket 1. The guide plate 6-3 deforms towards the middle of the microswitch 2 under the combined action of the guide surface 6-1 and the guide groove 4-8, and the abutting plate 6-4 deforms along with the guide plate 6-3. During this process, the stepped surface of the support surface 6-2 that abuts against the end surface of the movable plate 4-3 does not change. At this time, the movable plate 4-3 moves relative to the abutting plate 6-4, so that the distance between the movable plate 4-3 and the abutting plate 6-4 decreases, facilitating a certain amount of movement of the microswitch 2; When the trigger head 2-1 of the microswitch 2 moves further, along with the further deformation of the guide plate 6-3, the stepped surface of the support surface 6-2 that abuts against the end surface of the movable plate 4-3 changes, and the movable plate 4-3 moves relative to the support surface 6-2, thereby further reducing the distance between the movable plate 4-3 and the abutting plate 6-4, facilitating further movement of the microswitch 2, increasing the movable stroke of the microswitch 2, and preventing the microswitch 2 from being damaged.

[0033] On both sides of the fixed plate 4-2, first bending plates 4-5 are provided. The movable plate 4-3 is arranged within the first bending plates 4-5, and the movable plate 4-3 is wrapped by the first bending plates 4-5 to prevent external components from interfering with the movement of the movable plate 4-3. Second bending plates 4-10 are provided on both sides of the movable plate 4-3, and the second bending plates 4-10 are adapted to the end surface of the fixed plate 4-2 to control the movement amount of the movable plate 4-3.

[0034] On the socket 1, a mounting boss 1-3 is provided, and a lock core hole 1-4 is provided within the mounting boss 1-3. The electronic lock 3 is fixed to the outside of the socket 1 through the mounting boss 1-3, and the electronic lock 3 is adapted to the lock core hole 1-4.
