Wherein, the guide portion of the trigger 120 and the matching portion of the power input 331 are in contact and matching under the cooperation and guidance between the guide hole 310b of the support frame 310 and the guide portion of the trigger 120.

[0040] The power output 332 is connected with the power input 331, and the protection door 320 is connected with the power output 332. The directional movement of the power input 331 can drive the power output 332 to move the protection door 320 to the open position.

[0041] The power input 331 is rotatably arranged on the support frame 310. When the guide portion of the trigger 120 is plugged with the guide hole 310b of the support frame 310, the trigger portion of the trigger 120 can drive the matching portion of the power input 331 to rotate, so as to drive the power output 332 to move the protection door 320 to the open position.

[0042] In the embodiment, the trigger member 120 comprises a trigger rod, the trigger portion and the guide portion are arranged on the outer surface of the trigger rod 120, the power input member 331 is a cam member, the matching portion is a part of the outer edge surface of the cam member, when the trigger rod is moved to the plug-in direction X to make the trigger portion abut against the part of the outer edge surface of the cam member and drive the cam member to rotate, the cam member drives the power output member 332 to move to drive the protective door 320 to move from the closed position to the open position.

[0043] In detail, as shown in Figure 4 and Figure 5 , the charging plug 110 and the trigger member 120 of the charging device 100 are arranged in parallel and spaced apart, when charging, the charging device 100 approaches the power receptacle 200 along the plug-in direction X, the trigger member 120 can guide the charging plug 110 of the charging device 100 to smoothly plug into the plug-in port 210 of the power receptacle 200, at the same time, the trigger power input member 331 drives the power output member 332 to drive the protective door 320 to move to the open position. The charging plug 110 is, for example, a charging pin, and the plug-in port 210 of the power receptacle 200 is, for example, a power receptacle hole matched with the charging pin.

[0044] In combination with Figures 1 to 5 , the protective door 320 is connected to the support frame 310, and the support frame 310 further comprises a sleeve joint hole 310a, the sleeve joint hole 310a and the guide hole 310b are arranged in parallel and spaced apart, wherein the sleeve joint hole 310a is sleeved on the power receptacle 200, or in other words, the support frame 310 is connected to the power receptacle 200 through the sleeve joint hole 310a, the trigger member 120 of the charging device 100 is plugged into the guide hole 310b to guide the charging plug 110 to be plugged into the plug-in port 210 of the power receptacle 200 in the sleeve joint hole 310a, specifically, the axes of the sleeve joint hole 310a and the guide hole 310b extend along the plug-in direction X.

[0045] The protective door 320 comprises a roller shutter door 321, and further comprises a roller shutter door shaft 322, the roller shutter door 321 is arranged around the roller shutter door shaft 322 connected to the support frame 310, the power output member 332 is in transmission connection with the roller shutter door shaft 322, and the driven mechanism 330 further comprises a transmission member 333, the power input member 331, the transmission member 333, the power output member 332 and the roller shutter door shaft 422 are in transmission connection in sequence, so that when the trigger portion of the trigger member 120 drives the matching portion of the power input member 331 to move, the roller shutter door 321 can be moved to the open position.

[0046] Along the plug-in direction of the trigger member 120 and the guide hole 310b, the power input member 331 is located downstream of the entrance of the guide hole 310b; the roller shutter door 321 is arranged corresponding to the sleeve joint hole 310a, that is, when the roller shutter door 321 is opened, the plug-in port 210 of the power receptacle 200 sleeved by the sleeve joint hole 310a is exposed (as Figure 3 andFigure 5 As shown in the figure, when the roller shutter door 321 is closed, the plug interface 210 of the power receiving socket 200 sleeved by the sleeve joint hole 310a is shielded (as shown in the figure) Figure 2 And Figure 4 As shown in the figure, the effect of protection is achieved. The trigger 120 drives the power input 331, and the power input 331, the transmission 333, the power output 332 and the roller shutter door shaft 422 are sequentially transmissionally connected. The roller shutter door 321 moves to have a closed position of closing the plug interface 210 and an open position of exposing the plug interface 210.

[0047] Before the charging plug 110 of the charging device 100 is plugged with the power receiving socket 200, the trigger 120 is in contact with the matching part of the power input 331 in the plug direction X to drive the roller shutter door 321 to move from the closed position to the open position. As shown in the figure Figure 4 As shown in the figure, when the roller shutter door 321 is in the closed position, the charging plug 110 of the charging device 100, the roller shutter door 321 and the power receiving socket 200 are sequentially arranged in the plug direction X, and the trigger 120 of the charging device 100 and the power input 331 of the protection device 300 are sequentially arranged.

[0048] The present application drives the trigger 120 to contact with the matching part of the power input 331 by the driving force when the charging plug 110 of the charging device 100 is plugged with the power receiving socket 200, so that the roller shutter door 321 moves from the closed position to the open position. Compared with the manual opening of the charging port, the protection device provided by the present application simplifies the opening process of the charging port. Compared with the motor opening of the charging port, the protection device provided by the present application improves the reliability and reduces the cost. In addition, in the present application, the power input 331 is located downstream of the entrance of the guide hole 310b along the plug direction X of the trigger 120 and the guide hole 310b. The trigger 120 is arranged on the trigger rod which is spaced apart from the charging plug 110. Compared with the direct arrangement of the trigger 120 on the charging plug 110 and the arrangement of the power input 331 adjacent to the roller shutter door 321, it is beneficial to reduce the probability of accidental touching of the charging plug 110 and the power input 331 under the premise of ensuring the stability of the movement of the charging plug 110, which can prevent the charging port from being accidentally opened and improve the reliability of the charging connection equipment.

[0049] In an embodiment of the charging connection device provided by the application, the trigger rod integrates the functions of triggering and guiding, or the trigger piece 120 is fixedly connected with the guide rod of the charging device 100 to form the trigger rod, the trigger part and the guide part of the trigger rod are both circular in cross section perpendicular to the plug-in direction X, the trigger part is arranged at the head of the trigger rod, and the cross-sectional size at the position of the trigger part is smaller than the cross-sectional size at the position of the guide part. Of course, in other embodiments, the trigger piece 120 can also be fixedly connected to one side of the guide rod, as long as the trigger part can drive the power input piece 331 to move in the process of plugging the trigger piece 120 into the guide hole 310b, so that the matching part of the moving power input piece 331 can drive the roller shutter door 321 to move from the closed position to the open position, and the application does not make specific limitations.

[0050] In an embodiment of the charging connection device provided by the application, the charging plug 110 is columnar in shape and extends along the plug-in direction X, and the guide rods are two parallel rods, which are arranged on the left and right sides of the charging plug 110, for example. As shown in Figure 3 , the support frame 310 has two guide holes 310b, and the two guide holes 310b are respectively plugged into the two guide rods. However, it should be noted that the trigger piece 120 can be integrated with one of the guide rods, for example, as shown in Figure 1 and Figure 4 , the guide rod on the display side is the trigger piece 120, which has both the trigger part and the guide part, and the guide rod on the non-display side only has the function of guiding.

[0051] In an embodiment of the application, one of the guide rods is detachably connected to the body of the charging device 100, and the trigger piece 120 is arranged on the detachable guide rod. When the trigger piece 120 is abnormally damaged or worn after being matched with the power input piece 331 for many times, the detachable guide rod can be replaced alone, which reduces the maintenance cost of the charging connection device, and by arranging two guide rods on the left and right sides of the charging plug 110, the size of the trigger piece 120 is reduced under the premise of improving the movement stability of the trigger piece 120, and the compactness of the structure of the charging connection device is improved.

[0052] Further, as shown in Figures 1 to 3 and Figure 6 , Figure 8As shown, the support frame 310 comprises a protective cover 311 and a base 312, the base 312 is connected to the power socket 200, and the protective door 320 is installed on the base 312. Among them, the protective cover 311 and the base 312 are sequentially arranged along the plug-in direction X, the protective cover 311 is trumpet-shaped and is arranged closer to the charging device 100 relative to the base 312, and is used to guide the plug-in cooperation of the trigger 120 of the charging device 100 and the guide hole 310b. And the protective cover 311 of the embodiment can also play a protective role for the power input member 331, which can prevent the power input member 331 from being touched by foreign matter and causing the roller shutter door 321 to be mistakenly opened.

[0053] As shown in Figure 6 and Figure 7 specifically, the protective cover 311 comprises a guide surface 3111 for cooperating with the trigger 120, and the guide hole 310b comprises a first hole 310b1 arranged on the protective cover 311 and extending along the plug-in direction X. Along the plug-in direction X, the first hole 310b1 and the power input member 331 are sequentially arranged, and the first hole 310b1 is in communication with the guide surface 3111. During the plug-in process of the charging device 100 along the plug-in direction X, the trigger 120 is guided into the first hole 310b1 of the guide hole 310b through the guide surface 3111, and then the trigger 120 is in contact with the cooperating part of the power input member 331 to drive the roller shutter door 321 to move from the closed position to the open position. After the trigger 120 and the first hole 310b1 are plug-in cooperated, the cooperating part of the trigger 120 and the power input member 331 is in contact, which can improve the stability of the cooperating part of the trigger 120 and the power input member 331 in contact, thereby facilitating the stable driving of the roller shutter door 321 to move from the closed position to the open position, thereby improving the reliability and service life of the trigger 120, the power input member 331 and the roller shutter door 321.

[0054] In combination with Figures 3 to 7 , the power input member 331 is a cam member, which is rotatably arranged on the base 312 along the rotation axis direction Y, wherein the power input member 331 and the sleeve hole 310a are arranged along the rotation axis direction Y. When the roller shutter door 321 is in the closed position, along the plug-in direction X, the distance between the charging plug 110 of the charging device 100 and the roller shutter door 321 is greater than the distance between the trigger part of the trigger 120 arranged on the charging device 100 and the power input member 331. Therefore, during the movement of the charging device 100 along the plug-in direction X, the trigger 120 and the power input member 331 are in contact first, and after the cooperating part of the trigger 120 drives the power input member 331 to drive the roller shutter door 321 to move to the open position, the charging plug 110 of the charging device 100 reaches the power socket 200 and can be smoothly plug-in with the plug-in port 210 of the power socket 200.

[0055] The plug-in direction X and the rotation axis direction Y are arranged at an angle, and in the embodiment, the plug-in direction X is perpendicular to the rotation axis direction Y, but the application is not limited thereto.

[0056] The application converts the linear movement of the trigger 120 into the rotation of the power input 331, thereby further improving the stability and compactness of the charging connection device.

When the trigger part 121 moves to the installation slot 3121, the trigger part 121 can extend into the installation slot 3121 and be located at the driving position. The trigger part 121 can cooperate with the power input part 331 and drive the power input part 331 to move, so that the moving power input part 331 can drive the protective door 320 to move from the closed position to the open position. Specifically, the trigger part 121 can be made of elastic material. When the trigger part 121 is arranged at a distance from the installation slot 3121, the trigger part 121 can move to the avoiding position under the limitation of the guide hole 310b and overcome the elastic force of itself.
