DETAILED DESCRIPTION

[0025] In order to make the purpose, technical scheme and advantages of the embodiment of the utility model more clear, the technical scheme in the embodiment of the utility model will be described clearly and completely below by combining with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without making creative labor belong to the protection scope of the utility model.

[0026] The embodiments of the utility model will be described below by combining with Figures 1 to 6 .

[0027] According to the embodiment of the utility model, on the one hand, as Figures 1 to 4As shown, a shielding mechanism 100 is provided, comprising: a rotating sleeve 1; a lifting shaft 2 arranged in the rotating sleeve 1 and movable along the axial direction of the rotating sleeve 1, the upper end of the lifting shaft 2 forming a battery abutting end 21; an elastic member 3 adapted to apply an elastic force along the axial direction to the lifting shaft 2; a transmission member 4 and a guide groove 5, the transmission member 4 being inserted in the guide groove 5, one of the transmission member 4 and the guide groove 5 being arranged on the lifting shaft 2, and the other of the transmission member 4 and the guide groove 5 being arranged on the rotating sleeve 1; under the action of the force of the battery abutting end 21 or the elastic force of the elastic member 3, the lifting shaft 2 is adapted to move along the axial direction and make the transmission member 4 relatively slide along the guide groove 5, so as to make the rotating sleeve 1 rotate around the axial direction; and a shielding structure 8 connected with the rotating sleeve 1.

[0028] By using the shielding mechanism 100 of the embodiment, the self-weight of the battery or the elastic force of the elastic member 3 is used to make the lifting shaft 2 move along the axial direction, and in the process of moving the lifting shaft 2, the rotating sleeve 1 is made to rotate through the cooperation of the transmission member 4 and the guide groove 5, so as to make the shielding structure 8 rotate, so as to shield the electrical connector 200 or avoid the battery, without affecting the electrical connection between the battery and the electrical connector 200, while meeting the shielding protection of the electrical connector 200 in the battery replacement process, avoiding the dust and rain from falling into the electrical connector 200, and thus avoiding the problems of short circuit and poor contact of the electrical connector 200.

[0029] It should be noted that, in the embodiment, as shown in Figures 1 to 3 , the upper end of the lifting shaft 2 can extend out of the upper end of the rotating sleeve 1, so as to abut against the battery. Of course, in other alternative embodiments, the upper end of the lifting shaft 2 can always be located inside the rotating sleeve 1, and the battery can be inserted into the rotating sleeve 1 to abut against the upper end of the lifting shaft 2.

[0030] It should be noted that the axial direction of the rotating sleeve 1 is the axial direction of the lifting shaft 2, that is Figure 2 the vertical direction as shown.

[0031] It should be noted that, in the related art, in order to realize the protection of the electrical connector 200 in the battery replacement process, one method is to shield through the vehicle cabin, which will cause the overall vehicle weight to increase and the shielding range to be limited; another method is to control the rain cover to shield through the control program, and the overall structure and control program are complex, the stability is poor, the maintainability is low, and the cost is high; and another method is to trigger the cam connecting rod mechanism through the spring mechanism, so as to drive the waterproof shielding plate to shield or avoid, and the overall structure is complex, the maintainability is low, and the space occupation is large. In the embodiment, please refer to Figure 5 and Figure 6The shielding structure 8 has a shielding position and a clearance position. Under the weight of the battery (applied to the battery contact end 21) or the elastic force of the elastic element 3, the lifting shaft 2 moves axially, and under the interaction of the transmission element 4 and the guide groove 5, the rotating sleeve 1 rotates around the axis, thereby switching the shielding structure 8 between the shielding position and the clearance position. The shielding mechanism 100 has a simple overall structure, is easy to operate, occupies little space, is easy to maintain, and has a low cost.

[0032] Specifically, in this embodiment, before the battery is installed, the shielding structure 8 is in the shielding position (see [link]). Figure 5 When installing the battery, the battery abuts against the battery contact end 21 of the lifting shaft 2. The weight of the battery is applied to the lifting shaft 2 through the battery contact end 21, causing the lifting shaft 2 to descend. Under the interaction of the transmission component 4 and the guide groove 5, the rotating sleeve 1 rotates in the positive direction, and at the same time, the shielding structure 8 rotates in the positive direction to the avoidance position, so that the battery can be inserted and engaged with the electrical connector 200. At this time, the elastic element 3 stores energy. When it is necessary to remove the battery for replacement, the battery is lifted, and the elastic element 3 releases energy to make the lifting shaft 2 rise. Under the interaction of the transmission component 4 and the guide groove 5, the rotating sleeve 1 rotates in the opposite direction, and at the same time, the shielding structure 8 rotates in the opposite direction to the shielding position, so that the shielding structure 8 protects the electrical connector 200.

[0033] In one embodiment, such as Figures 1 to 3 As shown, the blocking mechanism 100 also includes a guide structure 6; a transmission component 4 is disposed on the lifting shaft 2, and the lifting shaft 2 and / or the transmission component 4 are axially movably connected to the guide structure 6; or, the transmission component 4 is disposed on the rotating sleeve 1, and the lifting shaft 2 is axially movably connected to the guide structure 6.

[0034] Specifically, in this embodiment, such as Figure 1 and Figure 2 As shown, the transmission component 4 is disposed on the lifting shaft 2, and correspondingly, the guide groove 5 is disposed on the rotating sleeve 1. The guide structure 6 has a limiting groove 61 opened along the axial direction, and the transmission component 4 passes through the guide groove 5 and is inserted into the limiting groove 61. Furthermore, when the blocking structure 8 is in the blocking position, the transmission component 4 is located at the upper end of the guide groove 5 and / or the limiting groove 61; when the blocking structure 8 is in the avoidance position, the transmission component 4 is located at the lower end of the guide groove 5 and / or the limiting groove 61.

[0035] It is worth noting that, in this embodiment, as Figure 2 As shown, the upper and lower ends of the limiting groove 61 are on the same axis, as... Figure 1As shown, the upper end and the lower end of the guide groove 5 are not on the same axis, that is, the upper end and the lower end of the guide groove 5 have an included angle in the circumferential direction. Further, in the embodiment, the included angle of the upper end and the lower end of the guide groove 5 in the circumferential direction is 90°, that is, when the shielding structure 8 is converted between the shielding position and the avoiding position, the rotation angle of the shielding structure 8 is 90°. Of course, in other alternative embodiments, the included angle of the upper end and the lower end of the guide groove 5 in the circumferential direction can also be set to other angles, for example, 180°, etc., and the specific angle value can be set according to actual needs.
