DETAILED DESCRIPTION

[0034] See also Figure 1-Figure 13In an embodiment of the present invention, a vehicle charger installation mechanism includes a vehicle charger body 1, and the vehicle charger body 1 is detachably installed on the vehicle through a vehicle charger installation beam 2. Preferably, the lower part of the rear floor of the vehicle should have a skeleton structure for the rear floor panel 8, which is generally a frame structure formed by overlapping the longitudinal beam 7 at the lower part of the rear floor and the rear cross beam 9 at the lower part of the rear floor. The vehicle charger body 1 is detachably mounted with a vehicle charger installation beam 2, and two vehicle charger installation beams 2 are symmetrically arranged, each of which provides two installation points for the vehicle charger body 1, for a total of four installation points, corresponding to the attached Figure 1 As shown, the installation point is the first assembly hole 21, the front end of the on-board charger installation beam 2 is overlapped with the middle of the rear cross beam 9 at the lower part of the rear floor, and the rear cross beam 9 at the lower part of the rear floor is overlapped with the rear panel 100 of the vehicle. The material used for the on-board charger installation beam 2 on the on-board charger body 1 should ensure the installation strength required for installation. The thickness of the steel used for the on-board charger installation beam 2 should be greater than 1mm, the yield strength of the steel used for the on-board charger installation beam 2 is not less than 340MPa of the elastic clip, and the tensile strength of the steel used for the on-board charger installation beam 2 is not less than 590MPa. The cross-sectional width of the on-board charger installation beam 2 is 30mm to 50mm, and the cross-sectional height is 10mm to 30mm. Among them, a protective cover 3 is provided on the outer movable cover of the vehicle charger body 1 on the side away from the vehicle charger mounting beam 2, and a guard plate 31 is fixedly provided on the side of the protective cover 3 away from the vehicle charger body 1. Adjusting parts 4 are symmetrically assembled and connected on both sides of the protective cover 3. The adjusting parts 4 are slidably adapted to the side grooves 12 embedded in the side of the vehicle charger body 1. The protective cover 3 can slide relative to the vehicle charger body 1 through the cooperation of the adjusting parts 4 and the side grooves 12. When the protective cover 3 moves horizontally relative to the vehicle charger body 1 so that the end of the adjusting part 4 moves to the end of the side groove 12, the adjusting part 4 can move toward the direction of the vehicle charger body 1. At this time, the protective cover 3 and the vehicle charger body 1 cannot move horizontally relative to each other, and the protective cover 3 and the adjusting part 4 can rotate relative to each other.

[0035] Through this structure, the deficiencies of the prior art are improved. The on-board charger body 1 is arranged at the lower part of the rear floor of the vehicle, so that the rear luggage compartment space of the vehicle is maximized. At the same time, the four mounting points (first assembly holes 21) of the on-board charger body 1 and the vehicle body are installed on two identical on-board charger mounting beams 2, which reduces the assembly tolerance between multiple mounting points, and the on-board charger mounting beams 2 are mounted on the rear floor beam system frame in front and behind, which can meet the strength requirements of the on-board charger installation. Moreover, the overall disassembly is relatively convenient and safer when used. The shield 3 and the guard plate 31 can cooperate to protect the inside of the on-board charger body 1. When needed, the shield 3 can also be slid to expose the bottom of the on-board charger body 1 for use, and the shield 3 rotates and stays on the side of the on-board charger body 1, which can still play a protective role. The overall structure is easy to operate, comprehensive protection, and easy to disassemble, maintain and use.

[0036] Among them, Figure 1-Figure 2 and Fig.13 As shown, the on-board charger installation beam 2 is symmetrically provided with first assembly holes 21 on both sides, and the first assembly holes 21 are located at the edge of the on-board charger installation beam 2. After the bolts / screws pass through the first assembly holes 21, the on-board charger installation beam 2 can be assembled between the rear floor lower longitudinal beam 7 and the rear floor lower rear cross beam 9, and the on-board charger installation beam 2 is also provided with a second assembly hole 22 between the two first assembly holes 21, and the on-board charger installation beam 2 can be assembled to the on-board charger body 1 by installing bolts / screws in the second assembly holes 22. In order to facilitate the matching, the connection between the bolts / screws and the rear floor lower longitudinal beam 7 and the rear floor lower rear cross beam 9 is provided with washers, so that there is a gap between the edge of the shield 3 and the rear floor lower longitudinal beam 7 and the rear floor lower rear cross beam 9, so as to facilitate the shield 3 to slide relative to the on-board charger body 1. The shield 3 is preferably a "U"-shaped structure, with a guard plate 31 integrally arranged at the bottom of the shield 3. A groove 32 is symmetrically embedded on the upper edge of the shield 3 on the side opposite to the opening, and the end of the on-board charger mounting beam 2 passes through the groove 32. This can ensure the detachable assembly of the on-board charger mounting beam 2 without affecting the sliding of the shield 3 relative to the on-board charger body 1. During the sliding process, the bolts / screws can pass through the upper side of the groove 32.

[0037] like Figure 2-Figure 4As shown, a plurality of groups of air holes 3103 are evenly distributed on the surface of the guard plate 31, a wire groove 3101 is embedded in the middle of the guard plate 31, and the wire groove 3101 extends from the side of the shield 3 away from the opening to the side of the opening of the shield 3, and the wire groove 3101 is connected to the side of the opening of the shield 3 close to the shield 3. A connector groove 3102 is provided, and a connecting wire 11 is electrically connected to the vehicle charger body 1, and a connector is provided at the end of the connecting wire 11. In this way, when the shield 3 is covered on the periphery of the vehicle charger body 1, the connecting wire 11 is arranged in the wire groove 3101, and the connector at the end of the connecting wire 11 is stuck in the connector groove 3102. When the shield 3 slides relative to the vehicle charger body 1, it can not only continuously protect the connecting wire 11, but also will not affect the connecting wire 11.

[0038] like Figure 7-Figure 9 As shown, the two sides of the shield 3 are symmetrically penetrated with the sockets 33, and the adjusting member 4 passes through the sockets 33 and is movably connected. The socket 33 includes a circular hole 3301 and a square hole 3302 that are connected. The square hole 3302 is located on the side close to the on-board charger body 1. The end of the adjusting member 4 close to the on-board charger body 1 is slidably adapted to the side groove 12, and the end is slidably adapted to the square hole 3302. The square hole 3302 is a prismatic structure, preferably a rectangular hole, and the diameter of the cross section of the circular hole 3301 is the same as the cross-sectional width of the square hole 3302. In this way, the part of the adjusting member 4 that matches the square hole 3302 cannot be returned to the circular hole 3301, so the adjusting member 4 will not fall off, and when the adjusting member 4 is pushed toward the on-board charger body 1, the part of the adjusting member 4 that matches the circular hole 3301 enters the square hole 3302 and can also maintain a stable fit.

[0039] Preferably, Figure 7-Figure 9As shown, the adjusting member 4 includes an insert rod 41, and the insert rod 41 and the circular hole 3301 can be axially slidably matched and relatively rotated. A slider 42 is fixedly connected to one end of the insert rod 41, and a disc 43 is fixedly connected to the other end of the insert rod 41. The slider 42 is slidably matched with the side groove 12, and the slider 42 is also axially slidably matched with the square hole 3302. In this way, when the slider 42 is located in the square hole 3302 and the side groove 12 at the same time during use, the shield 3 can only slide relatively with the on-board charger body 1. When the insert rod 41 and the slider When the block 42 is pushed into the vehicle charger body 1 at the same time, after the slider 42 disengages from the square hole 3302, a part of the rod 41 is pushed into the square hole 3302, so that the cylindrical rod 41 can rotate relative to the square hole 3302, and the rod 41 and the slider 42 will not rotate relative to each other because of the sliding fit between the slider 42 and the side groove 12. In this case, the shield 3 can realize relative rotation relative to the vehicle charger body 1 through the relative rotation between the rod 41 and the square hole 3302, and the open side of the shield 3 can be rotated away from the vehicle charger body 1.

[0040] Further, such as Figure 8-Figure 9 As shown, a plurality of groups of elastic clips 34 are arranged in a circular array in the circular hole 3301, and a clip hole 44 is embedded in the periphery of the insertion rod 41. The clip hole 44 is arranged opposite to the elastic clip 34, and two groups of clip holes 44 are arranged on the periphery of the insertion rod 41. When the slider 42 cooperates with the square hole 3302 and the side groove 12 at the same time, one group of clip holes 44 and the elastic clip 34 are elastically limited. When the insertion rod 41 and the slider 42 are pushed toward the side groove 12 and the slider 42 is completely separated from the square hole 3302, the other group of clip holes 44 and the elastic clip 34 form an elastic limit fit, which can ensure that the shield 3 remains stable during rotation.

[0041] Among them, Figure 8-Figure 9 As shown, the elastic clamp 34 includes a limiting protrusion 3401 that is slidably embedded in the inner wall of the circular hole 3301. The limiting protrusion 3401 is connected to the inner wall of the circular hole 3301 through a compression spring 3402. The portion of the limiting protrusion 3401 that extends into the circular hole 3301 is hemispherical, and the limiting protrusion 3401 is movably adapted to the clamping hole 44. In this way, the compression spring 3402 can provide a supporting force for the limiting protrusion 3401, so that the rotation angle of the shield 3 relative to the vehicle charger body 1 can have an adjustable limiting effect. If you want to adjust the angle, you only need to apply a force to overcome the supporting force of the compression spring 3402, so as to squeeze the limiting protrusion 3401 toward the inner wall of the circular hole 3301, so that the angle can be easily adjusted.

[0042] Among them, Figure 3 , Figure 6-Figure 7As shown, the side groove 12 includes a slide groove 1201 extending along the side of the on-board charger body 1, and a limiting groove 1202 is embedded in the side of the slide groove 1201 away from the opening side of the shield 3. The slide groove 1201 is slidably adapted to the slider 42, and the limiting groove 1202 is adapted to the size of the end of the slider 42, so that the slider 42 can slide on the slide groove 1201, thereby facilitating the sliding of the shield 3. When the shield 3 slides to the limit, the end of the slider 42 is aligned with the limiting groove 1202, and at this time, the slider 42 is pressed inward. The insertion rod 41 and the slider 42 are pressed, and the end of the slider 42 is inserted into the limit groove 1202, so that the slider 42 is disengaged from the cooperation with the square hole 3302, and the shield 3 can be rotated relative to the vehicle charger body 1 by the relative rotation between the insertion rod 41 and the square hole 3302. The shield 3 can rotate relative to the insertion rod 41, so as to facilitate the opening of the shield 3 to use the vehicle charger body 1, and also provide protection for the connector at the end of the wire 11 on the vehicle charger body 1 while using the vehicle charger body 1.

[0043] In specific use, such as Figure 1-Figure 2 , Figure 10-12 As shown, in order to prevent the shield 3 and the vehicle charger body 1 from sliding relative to each other in normal times, telescopic stoppers 5 are slidably embedded in the relatively close sides of the two groups of embedded grooves 32, and a driving member 6 is slidably embedded between the two groups of telescopic stoppers 5 on the shield 3. The driving member 6 slides and fits with the ends of the two groups of telescopic stoppers 5, and the end of the telescopic stopper 5 extends into the upper opening of the embedded groove 32. When the driving member 6 moves relative to the vehicle charger body 1, that is, when the driving member 6 is pushed toward the vehicle charger body 1, the end of the telescopic stopper 5 slides from the opening of the embedded groove 32 into the side wall of the embedded groove 32. In this way, under normal circumstances, the end of the telescopic stopper 5 extends into the upper opening of the embedding groove 32, so that the telescopic stopper 5 can cooperate to block the bolts / screws connected at the first assembly hole 21, so that the positions of the shield 3 and the vehicle charger body 1 are relatively stable. After the driving member 6 pushes the end of the telescopic stopper 5 to be retracted into the side wall of the embedding groove 32, there is no telescopic stopper 5 at the embedding groove 32 to block the bolts / screws connected to the first assembly hole 21, and the shield 3 can slide relative to the vehicle charger body 1. The overall operation is simple and convenient.

[0044] Among them, Figure 1-Figure 2 , Figure 10-12As shown, the telescopic stopper 5 includes a slide rod 51 slidably embedded in the side wall of the groove 32 and a bushing 52 fixedly sleeved on the periphery of the slide rod 51. The bushing 52 and the side wall of the groove 32 are slidably matched. The bushing 52 and the side wall of the groove 32 are connected by a spring. The spring acts on the slide rod 51 to move into the side wall of the groove 32. The driving member 6 supports and limits the movement of the slide rod 51 into the side wall of the groove 32. The driving member 6 includes a slide plate 61 which is slidably embedded in one side of the shield 3, and the two side edges of the slide plate 61 are slidably fitted with the ends of the two groups of slide bars 51 respectively. The slide plate 61 is preferably a rectangular thin plate, and a flange 64 is fixedly provided at one end of the slide plate 61. A spring is connected between the flange 64 and the inner side of the shield 3, and an arc plate 62 is provided at the end of the slide plate 61 away from the flange 64. The arc plate 62 and the slide plate 61 are integrated. The slide plate 61 is a semicircular plate, and a pressing head 63 is fixedly connected to the middle part of one side of the arc plate 62. The pressing head 63 can push the slide plate 61 and the arc plate 62 to move synchronously, so that the end of the slide bar 51 can gradually slide from the side of the slide plate 61 to the side of the arc plate 62, so that the slide bar 51 can slide into the side wall of the embedded groove 32. After releasing the hand, the slide bar 51 can be pushed and its end can return to the opening of the embedded groove 32 again.
