[0020] The utility model will be described in detail below in combination with the drawings and the specific implementation.

[0021] As Figure 1 , a charging seat for a rescue vehicle, comprising a seat body 100 and a charging plate 200.

[0022] As Figure 2 , the seat body 100 comprises a shell 110, the shell 110 is provided with a charging cavity 111, three sides of the charging cavity 111 are exposed to the outside world, the bottom plate of the charging cavity 111 is provided with two sliding channels 112, one seat body charging contact is respectively arranged in the two sliding channels 112: one seat body charging contact is a positive seat body charging contact 120, and one seat body charging contact is a negative seat body charging contact 140, the seat body charging contact is connected to the shell 110 through an elastic member, and the seat body charging contact can slide up and down in the sliding channel 112.

[0023] As Figures 4-6The charging plate 200 is Z-shaped and includes a mounting plate 210, a vertical plate 220, and a connecting plate 230 connected together. The lower surface of the connecting plate 230 is a recessed charging area 232. An insulating member 240 is fixed in the middle of the charging area 232. Each side of the insulating member 240 is provided with a charging contact for the charging plate: one charging contact is a positive charging contact 241 and the other is a negative charging contact 242. The charging contacts are fixed in the charging area 232 and are Z-shaped plates.

[0024] To reduce the difficulty of docking, the width of the positive terminal charging contact 241 and the negative terminal charging contact 242 is greater than half the width of the charging cavity 111.

[0025] like Figures 4-6 For secure mounting, the mounting plate 210 and the vertical plate 220 are fixed together by a reinforcing rib plate 211.

[0026] like Figures 4-6 To protect the cable, a cable sheath 260 is fixed on the vertical plate 220, with one end of the cable sheath 260 exposed on the upper surface of the mounting plate 210.

[0027] like Figures 4-6 In order to facilitate the entry of the power connector 230 into the charging chamber 111, the front end of the power connector 230 is provided with a bevel 231.

[0028] like Figures 2-3 The charging contacts of the base include electrical contacts 124, which are cylindrical. The cylindrical surface of the electrical contacts is used to connect to the charging contacts of the charging board. The electrical contacts 124 are rotatably connected to the electrical contact base 123. The electrical contact base 123 is connected to the fixing plate 121 through the elastic plate 122. The fixing plate 121 is fixed on the outer shell 110.

[0029] The electrical contact 124 is rotatable, which can reduce its friction with the charging contacts of the charging board.

[0030] In order to monitor the position of the charging contacts of the base, a position sensor 130 is fixed on the housing 110, and the contacts of the position sensor 130 abut against the electrical contact base 123.

[0031] Its working principle is as follows:

[0032] Install:

[0033] S1. Install the base 100: Connect two wires to the positive and negative terminals of the rescue vehicle's battery, and then pass the other end of the wire through the cable sheath 260 and connect it to the positive terminal charging contact 120 and the negative terminal charging contact 140 to the external power supply. Place the back of the base 100 (the side away from the charging chamber 111) against the indoor wall.

[0034] S2, install the charging plate 200: connect one section of the two sections of the wire to the rescue vehicle, pass the two sections of the wire through the cable sheath 260, and finally connect the positive charging plate charging contact 241 and the negative charging plate charging contact 242. Then install the mounting plate 210 on the rescue vehicle.

[0035] Use:

[0036] When the battery of the rescue vehicle is insufficient, the rescue vehicle automatically drives and performs alignment charging on the charging seat.

[0037] If the direction of the rescue vehicle aligning with the charging seat is tilted, one corner of the power connection plate 230 first enters the charging cavity 111, and as the power connection plate 230 gradually enters, the lower surface gradually presses the first electric contact 124, which is forced to move downward, and the elastic plate 122 is also bent downward. The power connection plate 230 continues to enter, and the electric contact 124 begins to contact the low position 244 of the charging plate charging contact.

[0038] As the power connection plate 230 continues to enter, the second electric contact 124 also contacts the low position 244 of the charging plate charging contact. At this time, the first electric contact 124 enters a deeper position and contacts the high position 243 of the charging plate charging contact or another low position 244 behind the high position 243 of the charging plate charging contact (whether the high position 243 or the low position 244 depends on the angle of the direction of the rescue vehicle aligning with the charging seat).

[0039] At this time, regardless of whether the electric contact 124 corresponds to the high position 243 or the low position 244, the two electric contacts 124 are in perfect contact with the charging plate charging contact by relying on the elastic force of the elastic plate 122.

[0040] When the vertical plate 220 contacts the front surface 115 of the seat body 100, the rescue vehicle cannot continue to advance and stops.

[0041] If the direction of the rescue vehicle aligning with the charging seat is correct, it is not repeated here.

[0042] Other contents refer to the prior art.

[0043] The above is only the preferred embodiment of the present application, and it should be pointed out that for those skilled in the art, without departing from the overall concept of the present application, a number of changes and improvements can be made, which should also be considered as the protection range of the present application.
