When the charging gun is inserted into the charging socket 10, the second switch is closed. The alarm 12 is fixedly installed on the upper part of the plug mounting frame 11.

[0031] Among them, the gravity switch device 3 includes a pressure plate 4, a pressure spring 6, a first switch box 7 and a pressure rod 8. One end of the pressure plate 4 is hinged to the vehicle loading plate 1 through a hinge 5. The pressure spring 6 is fixedly installed on the vehicle loading plate 1 and is located below the other end of the pressure plate 4. The pressure rod 8 is fixedly connected to the bottom surface of the pressure plate 4 by a thread and is located next to the pressure spring 6. The first switch box 7 is fixedly installed and connected to the bottom surface of the vehicle loading plate 1 and is located directly below the pressure rod 8. A first switch is arranged in the first switch box 7. The pressure rod 8 can be inserted into the first switch box 7 to disconnect the first switch.

[0033] The spring seat 702 is provided with a straight groove 703, the notch of the straight groove 703 is directed toward the first contact piece 705, the second contact piece 706 can move up and down in the straight groove 703, and the straight groove 703 can also limit the movement of the second contact piece 706 in other directions to avoid the second contact piece 706 from being misaligned with the first contact piece 705 during the up and down movement.

[0034] Among them, the pressure spring 6 is a disc spring, which has the characteristics of large load, short stroke, small required space, convenient combination and use, high economy and safety, and is suitable for workplaces with small space and large load.

[0035] Among them, the charging gun plug switch device 9 includes a second box body 901, a baffle 904, an automatic reset mechanism and a second switch. The charging socket 10 is fixedly installed inside the second box body 901. A slide groove 903 and a plug hole 902 that can expose the charging socket 10 are opened on the front of the second box body 901. The baffle 904 is close to the inner wall of the front of the second box body 901 and covers the charging socket 10. The baffle 904 is fixedly installed with a handle 905, and the handle 905 extends out of the slide groove 903 and can slide back and forth in the slide groove 903. The automatic reset mechanism is fixedly arranged at the bottom of the second box body 901 and fixedly connected to the baffle 904. The automatic reset mechanism is actuated under the action of external force to move the baffle 904 downward to expose the charging socket 10 and close the second switch. After the external force is released, the baffle 904 automatically moves upward to cover the charging socket 10 and disconnect the second switch.

[0036] Among them, the automatic reset mechanism includes a support plate 906, a guide column 907 and a second spring 908. The guide column 907 is fixed to the bottom of the second box body 901 by a threaded connection. The second spring 908 is loosely mounted on the guide column 907. The support plate 906 is loosely mounted on the guide column 907 and placed on the upper part of the second spring 908. The support plate 906 is welded to the lower end of the baffle 904. Under the action of the second spring 908, the support plate 906 keeps the baffle 904 on the upper part of the second box body 901 and covers the charging socket 10 to prevent dust, rainwater, etc. from entering the second box body 901.

[0037] Among them, the second switch includes a contact 909 and a reed 910. The reed 910 is fixedly installed at the bottom of the second box body 901. The contact 909 is welded to the bottom surface of the support plate 906 and is located directly above the reed 910. The contact 909 and the reed 910 are separated by a distance. After the external force acts on the support plate 906 and compresses the second spring 908, the contact 909 is tightly attached to the reed 910 to close the second switch. The non-contacting parts of the contact 909 and the reed 910 are provided with insulation protection to avoid leakage.

[0038] The alarm 12 is an audible and visual alarm, which emits both audible and flashing alarm signals to alert the driver.

[0039] Working principle of the present invention:

[0040] The alarm system is an alarm circuit composed of a first switch, a second switch and an alarm 12 connected in series.

[0041] When there is no vehicle on the vehicle loading plate 1, the pressure plate 4 is lifted up by the pressure spring 6, the pressure rod 8 is not in contact with the second contact piece 706, the second contact piece 706 is in close contact with the first contact piece 705 under the action of the first spring 704, the first switch is closed, the contact block 909 is separated from the reed piece 910 under the action of the second spring 908, the second switch is disconnected, the alarm circuit is disconnected, and the alarm 12 does not alarm.

[0042] When there is a vehicle on the vehicle loading plate 1 but it is not charging, the wheel presses on the pressure plate 4 so that the pressure rod 8 extends into the first switch box 7 and presses the second contact piece 706 to overcome the spring force of the first spring 704 and move downward, so that the second contact piece 706 is separated from the first contact piece 705, and the first switch is disconnected. At this time, the second switch is also in the disconnected state, the alarm circuit is disconnected, and the alarm 12 does not alarm.

[0043] When there is a car on the vehicle loading plate 1 and charging is to be performed, as mentioned above, the first switch is in the off state at this time. When the driver wants to charge the electric car, he only needs to move the handle 905 downward along the slide groove 903 by hand, and the baffle 904 moves downward accordingly to expose the charging socket 10. The electric car can be charged by inserting the charging gun into the charging socket 10. During the downward movement of the baffle 904, the support plate 906 is driven and then the contact block 909 is driven to move downward and contact the reed 910, and the second switch is closed. When the charging gun is inserted into the charging socket 10, the baffle 904 cannot move upward due to the obstruction of the charging gun, and the contact block 909 remains in contact with the reed 910, and the second switch continues to be in the closed state. Since the first switch is disconnected at this time, the alarm 12 does not alarm.

[0044] When the driver wants to pick up the electric car with the charging gun plugged in, he first pulls out the charging gun from the charging socket 10 and puts it away. The support plate 906 moves upward under the spring force of the second spring 908, and drives the baffle 904 and the contact block 909 to move upward at the same time. The baffle 904 covers the charging socket 10 to prevent rainwater and foreign objects from entering the second box body 901. The upward movement of the contact block 909 causes the contact block 909 to separate from the reed 910, and the second switch is disconnected. At this time, no matter whether the car is parked or leaving the loading plate 1, that is, no matter whether the first switch is closed or disconnected, the alarm circuit is disconnected, and the alarm 12 will not alarm.

[0045] When the driver wants to pick up the electric car with the charging gun plugged in, but forgets to unplug the charging gun from the charging socket 10 and drives away from the loading plate 1 directly, the car wheels leave the pressure plate 4, and the pressure plate 4 is lifted up by the pressure spring 6, and the pressure rod 8 moves up and separates from the second contact piece 706. The second contact piece 706 moves up under the action of the first spring 704 and fits tightly with the first contact piece 705, and the first switch is closed. Since the charging gun is still in the charging socket 10 at this time, the second switch is also in a closed state, the alarm circuit is connected, and the alarm 12 sends out an audible and visual alarm signal to remind the driver that the charging gun is not unplugged.

[0046] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
