Detailed Implementation

[0016] 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.

[0017] Figures 1 to 6 A charging device with a magnetically controlled mechanical lock according to one embodiment of the present invention is schematically shown. As shown, the charging device with a magnetically controlled mechanical lock includes: a housing 1, a mechanical lock 2, a magnetic element 3, a magnetic switch 4, a PCBA board 5, and a button 6; The outer casing 1 includes a front socket 10 and a rear housing 11 that are connected front and rear. The rear mounting platform 100 of the front socket 10 extends into the mounting cavity 110 of the rear housing 11. The rear mounting platform 100 is provided with a first through hole 101. The vertical sliding hole 111 of the rear housing 11 is directly opposite the rear end of the rear mounting platform 100 and has a vertical sliding connection button 6 inside it. The mechanical lock 2 is rotated and connected to the mounting platform 100 in the middle, with its rear upper surface contacting the button 6. The lower locking block 23 at the front end of the mechanical lock 2 can extend into or retract from the insertion cavity of the front socket 10 through the first through hole 101. Pressing the button 6 causes the mechanical lock 2 to rotate clockwise, and releasing the button 6 causes the mechanical lock 2 to rotate counterclockwise to reset. Preferably, it also includes an elastic component 7, which is connected to the front end of the mechanical lock 2. The elastic component 7 resets the mechanical lock 2 to rotate counterclockwise. The beneficial effect is that the elastic component 7 facilitates automatic reset and simplifies operation.

[0018] Magnetic element 3 is fixedly connected to the rear side of the mechanical lock 2. As the mechanical lock 2 rotates, magnetic element 3 moves closer to or further away from the magnetic switch 4. In the locked state, the magnetic element 3 and the magnetic switch 4 are far apart; in the unlocked state, they are closer together. Furthermore, an inclined mounting surface 21 is provided below the rear end of the mechanical lock 2. Mounting surface 21 is located to the upper right of magnetic element 3, and magnetic element 3 is fixedly connected to mounting surface 21. The inclined mounting surface 21 further optimizes the device size and facilitates interference-free rotation. Preferably, magnetic element 3 is a magnet, and mounting surface 21 has a normal groove 22 in which the magnet is embedded. The advantages of this configuration are: the magnetic element 3 has a simple structure, is easy to assemble, occupies little space, and has good magnetism.

[0019] The magnetic switch 4 is located behind the magnetic element 3 and is electrically connected to the front side of the PCBA board 5. The magnetic switch 4 is turned on or off as the magnetic element 3 approaches or moves away. Further, the magnetic switch 4 includes a longitudinal magnetic element 40, with right-angle connecting feet 41 at both ends. The vertical ends of the connecting feet 41 are welded to the second through-hole 51 of the PCBA board 5. Preferably, the magnetic switch 4 is a reed switch, and the stroke of the magnetic switch 4 is controlled by adjusting the interaction force between the reed switch and the magnetic element 3. Its advantages are: this setup has good sensing accuracy, and by using different models of magnetic switches 4 and different sizes of magnetic elements 3, magnetic induction linkage at various distances can be achieved.

[0020] PCBA board 5 is located inside mounting cavity 110 and connected to the rear side of mounting platform 100. It controls the circuit opening and closing based on the conduction or closing signal of magnetic switch 4 to realize the unlocking or locking of electromagnetic lock.

[0021] In one scenario, when button 6 is pressed, the rear end of the mechanical lock 2 is pressed down and rotates clockwise, and the magnetic switch 4 is brought close to the magnetic element 3 and becomes conductive. At this time, the elastic component 7 is compressed and deformed. When button 6 is released, the rear end of the mechanical lock 2 rotates counterclockwise under the restoring force of the elastic component 7, and the magnetic switch 4 is moved away from the magnetic element 3 and closes. In another scenario, when button 6 is pressed, the rear end of the mechanical lock 2 is pressed down and rotates clockwise, and the magnetic switch 4 moves away from the magnetic element 3 and closes. At this time, the elastic component 7 is compressed and deformed. When button 6 is released, the rear end of the mechanical lock 2 rotates counterclockwise under the restoring force of the elastic component 7, and the magnetic switch 4 moves closer to the magnetic element 3 and becomes conductive.

[0022] In either case, pressing button 6 will change the charging device from a locked state to an unlocked state.

[0023] The charging gun 01 is inserted into the insertion cavity and can push the lower locking block 23 to move upward. The mechanical lock 2 rotates clockwise and compresses the elastic component 7. When the insertion is completed, the positioning hole 011 of the charging gun 01 is located below the lower locking block 23. The elastic component 7 resets and causes the mechanical lock 2 to rotate clockwise, thereby pushing the lower locking block 23 to automatically fall into the positioning hole 011 to realize the locking action. When charging is complete, press button 6. The rear end of the mechanical lock 2 is pressed down and rotates clockwise, causing the lower lock block 23 to disengage from the positioning hole 011. The magnetic switch 4 moves away from the magnetic element 3 and closes. At this time, the elastic component 7 is compressed and deformed. The unlocking action is completed. The operator pulls out the charging gun 01. The elastic component 7 resets and causes the mechanical lock 2 to rotate clockwise, resetting the structure and waiting for the next charging. This charging device with a magnetically controlled mechanical lock uses a contactless switch, enabling near-field, contactless triggering of the mechanical lock and circuit control. The switch travel is controlled by adjusting the interaction force between the magnetic switch 4 and the magnetic element 3. Its advantages are: First, the switch travel can be varied according to requirements, and the size can be changed easily by selecting different models of magnetic switches 4 and magnetic elements 3 with different magnetic forces. This change has minimal impact on the overall size, effectively reducing the high-precision requirements for structural components. It has a wide range of travel adaptability and significantly reduces costs. Second, the structure is located between the original mechanical lock and the PCBA board 5, occupying minimal space and not affecting the placement of other components, making it suitable for compact applications. Third, the structure is simple, easy to install and maintain, and easy to operate.

[0024] Furthermore, the magnetic element 3 is located to the upper right of the magnetic switch 4 and to the upper left of the rotation shaft hole 20 of the mechanical lock 2. The magnetic element 3 reciprocates above the magnetic switch 4 and the rotation shaft hole 20, that is, the magnetic element 3 rotates within the second quadrant. The mechanical lock 2 rotates clockwise to bring the magnetic element 3 closer to the magnetic switch 4, and rotates counterclockwise to move the magnetic element 3 away from the magnetic switch 4. Its advantages are: the structure is compact, linkage can be achieved with small-angle rotation, and interference is effectively avoided.

[0025] Furthermore, the button 6 includes a cylindrical first body 60. The upper end of the first body 60 is integrally provided with a large-sized cap 61, and the lower end of its outer wall is provided with a limiting platform 62. A small-diameter pressure head 63 protrudes from the lower center of the first body 60. The first body 60 is vertically connected to a sliding hole 111 of equal diameter. The cap 61 is located above the sliding hole 111, and the limiting platform 62 is located below the sliding hole 111. The pressure head 63 enters the mounting cavity 110 and presses against the upper surface of the rear end of the mechanical lock 2. Its beneficial effects are: the button 6 can achieve a smooth, jam-free triggering action, operates without jamming for extended periods, and has a long service life.

[0026] Preferably, the upper surface of the cap body 61 is spherical, and the pressure head 63 is a hemispherical structure; the first body 60 is symmetrically provided with notches and spring pieces 64 located within the notches, and a limiting platform 62 is integrally provided below the spring piece 64; the lower surface of the limiting platform 62 is chamfered. Its beneficial effect is that this setting further improves the smoothness of the triggering action.

[0027] Furthermore, the upper surface of the front end of the mechanical lock 2 is provided with a positioning post 24. The elastic component 7 includes a spring 71 and a limiting seat 72. The limiting seat 72 is connected to the rear mounting platform 100 by screws. The spring 71 is housed in a floating cavity with an open lower end of the limiting seat 72. The positioning post 24 is located at the lower end of the floating cavity and is bushed to the lower end of the spring 71. Preferably, the rear mounting platform 100 is provided with a screw hole post 103, and the two ends of the limiting seat 72 and the screw hole post 103 are fixedly connected by screws. Its advantages are: this setting facilitates installation and debugging, and the overall size is small.

[0028] Preferably, the rear mounting platform 100 further includes a rectangular first through hole 101 located between two screw post 103, the positioning hole 011 of the charging gun 01 is rectangular, and the lower locking block 23 is a rectangular post with its lower end face being inclined. The advantage of this arrangement is that it facilitates quick and easy insertion and mating of the charging gun and the mounting base.

[0029] Furthermore, two hinge blocks 102 are longitudinally and symmetrically connected as a single unit at the rear end of the rear mounting platform 100. The hinge shaft 8 is fixedly connected to the through holes of the hinge blocks 102 at both ends and rotatably connected to the rotating shaft hole 20 of the mechanical lock 2 with a small gap in the middle. Preferably, the hinge shaft 8 is a screw, which passes through the through hole and rotating shaft hole 20 of one hinge block 102 and is threadedly connected to the threaded hole of the other hinge block 102; or, one end of the hinge shaft 8 has a large-diameter positioning cap and the other end has an annular groove. The hinge shaft 8 is sleeved through and connected to the hinge blocks 102 with a gap, the positioning cap is fitted against the outer side of one hinge block 102, and the C-shaped retaining spring 9 mounted on the annular groove is fitted against the outer side of the other hinge block 102. The advantages are: this arrangement achieves good rotation effect, and the overall size is small, making installation convenient.
