[0033] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0034] like Figure 1-Figure 10 The vehicle-mounted charger with a protective structure shown in the figure includes a charger body 1, which is also often called a battery charging machine. It is a prior art and will not be described in detail. The lower surface of the charger body 1 is fixedly connected to a bottom frame 2, and a plurality of inclined columns 13 are elastically inserted on one side and the rear surface of the bottom frame 2, respectively. A pin 19 is elastically inserted at the lower end of the inclined column 13, and the upper end of the inclined column 13 extends to the inner side of the bottom frame 2 and is fixedly connected to an end block 14. Two support plates 3 are fixedly connected to the lower edge of the inner surface of the bottom frame 2, and a sliding block 4 is slidably connected to the upper surface of the support plate 3. One side surface of the sliding block 4 contacts the end block 14, and the other side surface of the sliding block 4 is fixedly connected to a moving clamping block 6, one side of the support plate 3 is fixedly connected to a bending plate 9, and one side of the bending plate 9 is fixedly connected to a fixed clamping block 10, an electric clamp 11 is clamped between the moving clamping block 6 and the fixed clamping block 10, and the end of the electric clamp 11 is attached to the inner wall of the bending plate 9, and a wire-receiving mechanism is provided on the rear surface of the charger body 1;

[0035] When the user removes the electric clamp 11 , the inclined column 13 moves upward, pushing the sliding block 4 to move horizontally.

[0036] like Figure 3 , Figure 4 , Figure 6 As shown, a guide bar 18 is convexly provided on the upper surface of the inclined column 13 to prevent the inclined column 13 from rotating relative to the bottom frame 2. A first compression spring 16 is sleeved on the upper end of the outer surface of the inclined column 13. An extension tube 17 is provided on the inner wall of the bottom frame 2 corresponding to the outer surface of each inclined column 13. The first compression spring 16 is located between the extension tube 17 and the end block 14. The extension tube 17 plays a role in supporting the lower end of the first compression spring 16. At the same time, the extension tube 17 provides space so that the inclined column 13 and the pin 19 can be hidden after moving up and will not fall to the inner side of the bottom frame 2.

[0037] like Figure 3 , Figure 4 , Figure 5 As shown, the upper end of the pin 19 is slidably inserted into the inner side of the inclined column 13, and the upper end of the pin 19 is fixedly connected to a sliding plate 21, and the lower side of the sliding plate 21 is fixedly connected to a guide block 22, and the inner surface of the inclined column 13 is provided with a strip groove 23, and the sliding plate 21 and the inner wall of the inclined column 13 are slidably matched, and the guide block 22 is slidably inserted into the inner side of the strip groove 23, and the inner side of the inclined column 13 is provided with a second compression spring 20, and the second compression spring 20 is located on the upper surface of the sliding plate 21. The design of the guide block 22 and the strip groove 23 can prevent the pin 19 from rotating relative to the inclined column 13.

[0038] like Figure 1 , Figure 6 , Figure 7 As shown, a cut surface 15 is respectively provided on one side and the upper surface of the end block 14. The cut surface 15 on one side can increase the contact area with the sliding block 4, and the cut surface 15 on the upper surface provides space for the inclined column 13 to move upward, preventing the problem of interference with upward movement caused by contact with the lower surface of the charging body 1.

[0039] like Figure 7 As shown, the upper surface of the support plate 3 is fixedly connected with an L-shaped rail 5, and the lower surface of the sliding block 4 is slidably sleeved on the outer surface of the L-shaped rail 5. It is relatively simple to adopt this solution to realize the sliding installation of the sliding block 4.

[0040] The moving clamp block 6 and the fixed clamp block 10 are provided with a protruding edge 7 on the side close to each other, and the protruding edge 7 holds up the lower surface of the electric clamp 11. The moving clamp block 6 and the fixed clamp block 10 are provided with inclined surfaces 8 on their lower surfaces. The inner wall of the bent plate 9 is provided with a first wire-passing opening 12, and one end of the electric clamp 11 is fixedly connected with a connecting wire 26. The lower surface of the bottom frame 2 is provided with a second wire-passing opening 25 at the rear, and the connecting wire 26 passes through the inner side of the first wire-passing opening 12 and the second wire-passing opening 25. Ensure that the connecting wire 26 can be led to the rear of the charging body 1.

[0041] like Figure 8 , Fig. 9 , Fig.10 As shown, the wire collection mechanism includes a collection box 24 fixedly mounted on the rear surface of the charging body 1, two hard wire tubes 27 are fixedly connected to one side of the collection box 24, a guide frame 29 is fixedly connected to one side of the upper side of the collection box 24, and a soft roller 28 is slidably connected to one side of the guide frame 29 through an elastic mechanism. The connecting wire 26 passes through the upper surface of the soft roller 28 and is guided to the inner side of the collection box 24, and the ends of the two connecting wires 26 pass through the hard wire tube 27 and are electrically connected to the charging body 1. The hard wire tube 27 can be made of plastic material, which is convenient for the connection position of the connecting wire 26 to be fixedly connected to the charging body 1.

[0042] The elastic mechanism includes a sliding opening 30 penetrating the side surface of the guide frame 29, a slider 31 is slidably inserted into the inner side of the sliding opening 30, a guide rod 32 is fixedly connected to the rear surface of the slider 31, the rear end of the guide rod 32 slides through the rear surface of the guide frame 29, a third compression spring 33 is sleeved on the outer side of the guide rod 32, and the third compression spring 33 is located on the inner side of the sliding opening 30. The slider 31 moves backwards and squeezes the third compression spring 33, and then the soft roller 28 can release the connecting wire 26, which is convenient for pulling and retracting the connecting wire 26.

[0043] During use, when placed in a location such as a car trunk, the two surfaces without the inclined column 13 are respectively attached to one side of the trunk and the back of the rear seat. During driving, the inclined support of the inclined column 13 and the pin 19 can prevent the charging body 1 from sliding, thereby effectively improving the stability of the charging body 1 during placement, preventing displacement during driving, thereby preventing collision damage, and achieving a good protective effect.

[0044] When bumps occur during driving, since the two sides of the charging body 1 are supported by one side of the trunk and the back of the rear seat respectively, these two sides are relatively stable. Therefore, as the car bumps, the other two sides and the pins 19 at the bottom of the trunk will slide relatively along the inner side of the inclined column 13, squeezing the second compression spring 20 to achieve the conversion between kinetic energy and elastic potential energy, thereby achieving a buffering effect, thereby achieving a protective effect, preventing damage caused by excessive contact and collision with the bottom of the trunk due to bumps.

[0045] When using the charger, the user moves the sliding block 4 horizontally, so that the movable clamp block 6 is first away from the fixed clamp block 10, and then the electric clamp 11 can be removed. After letting go, the end block 14 is pushed upward by the first compression spring 16, and the side cut surface 15 of the end block 14 pushes the sliding block 4 horizontally, so that the movable clamp block 6 moves horizontally. After the protruding edges 7 on both sides contact, the movement stops. At this time, the end of the pin 19 does not exceed the side of the bottom frame 2, so as to achieve the purpose of folding, prevent the problem of structural damage in this place during use, and ensure that the movement of the charging body 1 is not hindered. After use, push the electric clamp 11, and cooperate with the two inclined surfaces 8 to more conveniently squeeze the electric clamp 11 between the fixed clamp block 10 and the movable clamp block 6, so as to achieve the purpose of quick installation.

[0046] Under the elastic force of the third compression spring 33, the soft roller 28 will press the connecting wire 26 against the rear surface of the charging body 1. After removing the power clamp 11 and pushing the soft roller 28 forward, the connecting wire 26 can be dragged out of the collection box 24 to facilitate pulling the power clamp 11 to the use position for connection.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
