[0033] like Figure 1-3 As shown, an embodiment of the utility model provides a vehicle-mounted charging device, including a shell 100, fixed blocks 200 arranged on both sides of the same end of the shell 100, guide columns 300 arranged at opposite ends of the two fixed blocks 200, and a shielding assembly 400 for shielding the charging interface of the shell 100. Specifically, the shielding assembly 400 includes a slider 410, a tension spring 420, a baffle 430 and a limiter 440. The slider 410 is arranged on the guide column 300 and can slide along its axial direction. The tension spring 420 is sleeved on the guide column 300 and is located between the slider 410 and the fixed block 200. The baffle 430 is arranged on one side of the slider 410 and extends toward the tension spring 420 to shield the charging interface. The limiter 440 is used to fix the relative position of the baffle 430 to expose the charging interface.
[0034] In the embodiment of the utility model, when the charging interface needs to be used, the baffle 430 can be moved outward, and the slider 410 can slide on the guide column 300, so that the baffle 430 drives the slider 410 to move to one side and squeeze the tension spring 420 to deform, and the position of the baffle 430 is fixed by the limiter 440. At this time, the charging interface is exposed for charging. After charging is completed, the power cord is unplugged, and the baffle 430 is separated from the shell 100 by the limiter 440, and the slider 410 is pushed back to its original position under the action of the tension spring 420, so that the slider 410 drives the baffle 430 to cover the charging interface, which can effectively prevent dust and debris in the air from entering the charging interface when not in use, avoiding blockage and affecting the charging effect.
[0035] like Figure 1-2 As shown, in the embodiment of the utility model, four fixing blocks 200 are provided, and two of them are symmetrically arranged on the shell 100, two guide posts 300 are provided, and they are respectively provided between the two corresponding fixing blocks 200, two tension springs 420 are provided, and they are respectively sleeved on the two corresponding guide posts 300, and the two ends of the slider 410 are respectively provided on the two guide posts 300. By providing two parallel guide posts 300, the slider 410 and the baffle 430 can be more stable during the movement, and the two tension springs 420 facilitate the resetting of the slider 410 and the baffle 430.
[0036] like Figure 1-2 As shown, in the embodiment of the utility model, two sliders 410 are symmetrically arranged on the guide column 300, and two corresponding baffles 430 are also arranged. The two sliders 410 and the two baffles 430 move relative to or toward each other. When they move toward each other, the two baffles 430 respectively block the charging interface.
[0037] like Figure 1-2 As shown, in the embodiment of the utility model, a guide bar 500 is provided at one end of the fixed block 200 facing the slider 410, and the guide bar 500 is located above the baffle 430 so that the baffle 430 is flush with the surface of the charging interface, thereby improving the shielding effect of the charging interface.
[0038] like Figure 1-3 As shown, in the embodiment of the utility model, a pull plate 600 is vertically provided on the baffle 430 to facilitate people to move the baffle 430 and facilitate operation. At the same time, in order to prevent the pull plate 600 from slipping and affecting the operation, anti-slip protrusions or anti-slip patterns are provided at the opposite ends of the pull plate 600.
[0039] like Figure 3As shown, in the embodiment of the utility model, the limiting member 440 includes a compression spring 441 and a movable column 442, the baffle 430 is provided with a clamping hole 431, and a side wall of the shell 100 facing the baffle 430 is provided with a limiting groove 110, and the bottom of the limiting groove 110 is slidably connected to the movable column 442 through the compression spring 441, and the movable column 442 cooperates with the clamping hole 431. When in use, the movable column 442 can move vertically in the limiting groove 110 under the action of the compression spring 441, so that it can be clamped or separated from the clamping hole 431, and the position of the baffle 430 is limited and fixed. At the same time, in order to facilitate the clamping or separation of the movable column 442 from the clamping hole 431, a ball 443 is rotatably connected to the inner side of the top end of the movable column 442.
[0040] In the embodiment of the utility model, the center points of the compression spring 441 , the movable column 442 , the clamping hole 431 and the ball 443 are all on the same horizontal plane, which facilitates the stable limiting of the baffle 430 through the clamping hole 431 and the movable column 442 in the later stage.
[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
