Technical Field

[0001] This utility model relates to the field of new energy charging, and in particular to a photosensitive electronically controlled mechanical lock and a charging device using the same. Background Technology

[0002] New energy vehicle charging uses a matching charging gun and charging base. A mechanical lock is installed on the charging gun or charging base. The current linkage structure of this mechanical lock involves a microswitch installed below the pressing position of the lock body. The opening and closing of the control circuit is achieved by the opening and closing of the microswitch. Its drawbacks are: firstly, the microswitch has a short travel distance, requiring high precision in the manufacturing of the structural components to ensure the microswitch triggers within its travel distance, resulting in limited application and high cost; secondly, the microswitch is relatively large, requiring significant space. Therefore, the structural design needs to reserve a large space for the microswitch, affecting the placement of other components, making it particularly unsuitable for compact design scenarios.

[0007] A spring is installed on the front end of the opening mouth, and a limiting post is sleeved on the lower end of the spring. When the spring returns, it causes the lock body to rotate counterclockwise to reset.

[0008] A photosensitive switch is electrically connected to a PCBA board. The front end of the photosensitive switch has a through-beam light detection groove. The light is cut off by a boss that rotates clockwise or restored after the boss rotates counterclockwise, thus realizing the closing or conduction of the photosensitive switch.

[0009] The PCBA board is fixed at the rear end of the open cavity, and it controls the circuit's on / off state based on the conduction or closure signal of the photosensitive switch.

[0010] In some implementations, the photosensitive switch is a rectangular block, with its rear end electrically connected to the PCBA board and its front end having a rectangular groove-shaped detection slot, and the detection slot and the boss being spaced apart.

[0037] The present invention will now be described in further detail with reference to the accompanying drawings. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to the directions in the accompanying drawings, while the terms "inner" and "outer" refer to the directions toward or away from the geometric center of a specific component, respectively.

[0038] Figures 1 to 5 A photosensitive electromechanical lock according to one embodiment of the present invention is schematically shown. As shown, the photosensitive electromechanical lock includes:

[0039] The lock body 1 is rotatably located at the front end of the open mouth of the outer shell 01. The upper surface of the right end arm 12 of the lock body 1 is integrally connected to the limiting post 13 and the lower surface is integrally connected to the lock connector 15. The lock connector 15 cooperates with the positioning hole 031 of the charging gun 03. The left end pressure arm 11 of the lock body 1 has a boss 14 in the middle of the left end face.

[0040] Button 2, the limit cap 22 of button 2 is located outside the outer shell 01, the middle section 20 is vertically slidably connected to the sliding hole of the outer shell 01, and the lower end pressure head 21 is attached to the upper surface of the pressure arm 11. When button 2 is pressed, the lock body 1 and the boss 14 rotate clockwise.

[0042] A photosensitive switch 4 is electrically connected to a PCBA board 5. The front end of the photosensitive switch 4 has a through-beam detection groove 41. Preferably, the photosensitive switch 4 is a rectangular block, with its rear end electrically connected to the PCBA board 5 and its front end having a rectangular recessed detection groove 31. The detection groove 31 and the boss 14 are spaced apart. Light is cut off by the boss 14 rotating clockwise or restored after the boss 14 rotates counterclockwise, thus closing or connecting the photosensitive switch 4. The travel of the photosensitive switch 4 is controlled by the size of the boss 14 and is not controlled by photoelectric components.

[0043] PCBA board 5 is fixedly mounted at the rear end of the open cavity, and controls the circuit's on / off state based on the conduction or closure signal of photosensitive switch 4. Preferably, PCBA board 5 is connected to the rear side of mounting platform 020 by screws.

[0044] The charging gun 03 is inserted into the plug-in cavity 021 and can push the lock connector 15 to move upward. The lock body 1 rotates counterclockwise and compresses the spring 3. When the plugging is completed, the positioning hole 031 is located below the lock connector 15. The spring 3 returns to its original position and causes the lock body 1 to rotate clockwise, thereby pushing the lock connector 15 to automatically fall into the positioning hole 031, realizing the locking action of the lock body 1.

[0045] When charging is complete, press button 2. The lock body 1 moves counterclockwise, causing the lock connector 15 to disengage from the positioning hole 031 and the boss 14 to enter the detection slot 41. The photosensitive switch 4 sends a feedback signal to the PCBA board 5. The PCBA board 5 cuts off the circuit, completing the unlocking action. The operator pulls out the charging gun 03, and the spring 3 resets, causing the lock body 1 to rotate clockwise, resetting the structure and waiting for the next charging.

[0046] This photosensitive electromechanical lock uses a contactless switch. The travel of the mechanical lock's press depends on the size of the boss 14 and is not controlled by photoelectric components. The travel size can be changed according to the structural design. Its advantages are: First, the switch travel can be varied according to requirements, and the change is simple, requiring only the selection of the size of the boss 14. This change has minimal impact on the overall size, effectively reducing the high-precision machining requirements of related structural components. It has a wide range of travel adaptability and significantly reduces costs. Second, this structure is located between the original lock body and the PCBA board 5, occupying minimal space and not affecting the arrangement of other components, making it suitable for compact structural applications.

Preferably, the front end face of the boss 14 is an arc surface 141 and the rear end face is an inclined surface 142, with a transition fillet 143 between the arc surface 141 and the inclined surface 142. Its beneficial effect is that the boss 14 can achieve a large stroke in a small size, and the rotation is interference-free.

[0048] Furthermore, the front socket 02 has a mounting platform 020 at its rear end. The mounting platform 020 has two longitudinally symmetrical lugs 022 at its rear end and a first through hole 023 at its front center that connects to the insertion cavity 021. The lock body 1 is rotatably connected to the two lugs 022 via a hinge pin 6. The lock connector 15 passes through the first through hole 023 and enters the insertion cavity 021. The advantage is that the mounting platform 020 is simply machined from the outer periphery of the front socket 02, without increasing the product's volume, thus resulting in a compact overall structure.

[0049] Preferably, the lock body 1 includes a central hinge hole 10, a pressure arm 11 integrally connected to the left end of the central hinge hole 10, and a connecting arm 12 integrally connected to the right end of the central hinge hole 10; the upper surface of the connecting arm 12 is integrally connected to a limiting post 13 and the lower surface is integrally connected to a lock connector 15; a boss 14 is provided in the middle of the left end face of the pressure arm 11; the central hinge hole 10 is rotatably connected to the center of the hinge shaft 6, and two lugs 022 are fixedly connected to both ends of the hinge shaft 6. Preferably, the hinge shaft 6 is a screw, which passes through the through hole of one lug 022, the central hinge hole 10, and is threadedly connected to the threaded hole of the other lug 022; or one end of the hinge shaft 6 is provided with a large-diameter positioning cap and the other end is provided with an annular groove, the hinge shaft 6 is sleeved through and connected to the lugs 022, the positioning cap fits against the outside of one lug 022, and the C-shaped retaining spring 7 installed on the annular groove fits against the outside of the other lug 022.

[0052] On both sides of the first through hole 023, the mounting platform 020 is longitudinally symmetrically provided with two vertical screw posts 024, and the two end blocks 81 are connected to the screw posts 024 by screws. The advantages are: this arrangement facilitates installation and debugging, and the overall size is small.

[0053] Furthermore, the middle section 20 is cylindrical.
