[0053] As Figure 3 , Figure 8 , Figure 9 and Figure 10As shown, the installation seat 48 is located in the cavity 3 and detachably connected with the lower shell 2, the circuit board 4 is located between the installation seat 48 and the lower shell 2, the live plug body 34, the zero plug body 35 and the ground plug body 36 are all installed in the installation seat 48, the top of the installation seat 48 is provided with a rectangular groove 49, the bottom of the rectangular groove 49 is provided with a three-hole plug hole 50 and a two-hole plug hole 51 corresponding to the three-hole socket 32 and the two-hole socket 33 respectively, the rectangular groove 49 is provided with two safety doors 52 covering the live plug hole and the zero plug hole on the three-hole socket 32 and the two-hole socket 33 respectively, the safety door 52 is elastically and slidably connected with the rectangular groove 49, the opening end of the rectangular groove 49 is attached to the bottom of the upper shell 1, and the plug piece one 37 and the plug piece two 46 are both penetrated through the other end of the installation seat 48 and located outside the installation seat 48.

[0054] In the non-working state, the trigger 7 and the two supporting springs 20 are not in contact with and assembled with the micro switch 8, the two supporting springs 20 can abut against the top block 10 in the non-working state, so as to avoid the generation of shaking noise due to the shaking of the top block 10 during the movement of the vehicle, and the top block 10 will not contact the micro switch 8 in the non-working state, so as to protect the micro switch 8 from being damaged; in the switch loading posture (the switch is vertically assembled on the vehicle body), the top block 10 can be uniformly stressed, so as to ensure that the top block 10 can accurately trigger the micro switch 8 in the working state; the power socket is installed on the side of the trunk, which is convenient to operate, the socket can be used by the rear passengers, and the socket can also be used when the vehicle is parked outside, the plug pin on the plug is first pushed to move the transmission block 9 downward against the elastic action of the transmission spring 13, until the transmission block 9 contacts the connecting seat 18, then the top block 10 is moved downward against the elastic action of the supporting spring 20, until the trigger rod 11 contacts and triggers the micro switch 8, and the trigger signal can be powered on, when the plug is pulled out, the transmission mechanism is reset to the initial position, and no power is supplied.

[0055] In the above operation process, when the transmission block 9 continues to be pressed after contacting the connecting seat 18, the supporting spring 20 is gradually compressed, and the spring column 23 is limited by the surface of the circuit board 4, so that the micro switch 8 can be more effectively protected from force and damage.

[0056] In the non-working state, the trigger 7 and the two elastic needles 24 are not in contact with the micro switch 8 and have no assembly relationship, and the two elastic needles 24 can be pressed against the top block 10 in the non-working state to avoid the generation of shaking noise due to the shaking of the top block 10 during the movement of the vehicle. In the non-working state, the top block 10 will not contact the micro switch 8 to protect the micro switch 8 from being damaged; in the switch loading posture (the switch is vertically assembled on the vehicle body), the top block 10 can be uniformly stressed to ensure that the top surface of the top block 10 can accurately trigger the micro switch 8 in the working state; the power socket is installed on the side of the trunk, which is convenient to operate, and the socket can be used by the rear passengers or when used outside the house. When the plug is inserted into the safety door, the elastic clamping area 6 is pushed away, the pins on the plug first overcome the elastic action of the transmission spring 13 to push the transmission block 9 downward, and then the transmission block 9 is in contact with the connecting seat 18. After overcoming the elastic action of the elastic needle 24, the top block 10 is driven downward until the trigger rod 11 contacts and triggers the micro switch 8, and the trigger signal can be powered on. When the plug is pulled out, the transmission mechanism is reset to the initial position and is not powered.

[0057] In the above process, when the transmission block 9 is in contact with the connecting seat 18 and continues to be pressed down, the elastic needle 24 is gradually compressed, and the one end of the limiting tube 25 in a suspended state is limited by the surface of the circuit board 4. When it is further pre-pressed, the micro switch 8 can be more effectively protected from force and damage.

[0058] In the above embodiment one and embodiment two, when the transmission block 9 is in contact with the connecting seat 18 and continues to be pressed down, the one end of the guide rod 26 in a suspended state is limited by the lower shell 2. When it is further pre-pressed, the protection force of the micro switch 8 is further improved, so that the micro switch 8 is not stressed. In addition, the top of the top block 10 is located in the groove one 12, and the bottom of the top block 10 is located in the through hole two 27 through the guide rod 26 on the connecting seat 18, so that the transmission block 9 and the top block 10 can always produce vertical displacement change, further improving the uniformity of the stress of the top block 10, and ensuring that the trigger rod 11 can accurately trigger the micro switch 8 in the working state.

[0059] In the non-working state of the rubber body 29, the top block 10 can be pressed against the rubber body 29 to avoid the generation of shaking noise due to the shaking of the top block 10 during the movement of the vehicle, and the top block 10 will not contact the triggering pressing point of the micro switch 8 in the non-working state, so as to protect the micro switch 8 from being damaged; in the vehicle-mounted state of the switch (the switch is vertically assembled on the vehicle body), the top block 10 can be uniformly stressed, so as to ensure that the plane of the top block 10 can accurately trigger the micro switch 8 in the working state; the power socket is mounted on the side of the trunk, which is convenient for operation, and the socket can be used by the rear passengers or in the outdoor environment; when the plug is inserted into the safety door, the elastic clamping area 6 is pushed away, the pin of the plug first overcomes the elastic action of the transmission spring 13 to push the transmission block 9 downward until the transmission block 9 contacts the connecting seat 18, and then the top block 10 is driven to move downward after overcoming the elastic action of the rubber body 29 until the triggering rod 11 contacts the pressing area of the micro switch 8 to trigger the micro switch 8, and the triggering signal can be supplied with power; when the plug is pulled out, the transmission mechanism is reset to the initial position and is not powered.

[0060] The structure design of the rubber body 29 is beneficial to the balance of the top block 10 and the uniformity of the stress of the top block 10, so as to ensure that the triggering rod 11 on the top block 10 can accurately trigger the micro switch 8 in the working state; on the other hand, when the transmission block 9 continues to be pressed after contacting the connecting seat 18, the top of the rubber body 29 is compressed, and since the cover body 30 is reversely buckled on the micro switch 8, the opening end of the mounting groove 28 acts on the cover body 30 when the pre-pressing is further performed, so as to more effectively protect the micro switch 8 from being damaged.
