Description

Technical Field

[0001] The utility model relates to the field of vehicle tools, in particular to an automobile backstop. Background Art

[0002] In existing technology, cars use parking brakes to achieve parking. However, in many cases, parking brakes are not very reliable, especially electronic parking brakes. Failure of the electronic equipment can easily cause the electronic parking brake to malfunction. For example, when parking on a steep slope, the parking brake may not be tight enough, causing the vehicle to roll even after parking. In this case, a vehicle backstop is needed to assist in parking. The vehicle backstop is inserted under the car tires to effectively prevent the car from rolling. The vehicle backstop is not only used for parking, but also can help novice drivers start on a slope.

[0003] The existing anti-skid devices on the market are mainly fixed structures and foldable structures. The foldable structure can facilitate the storage and use of the anti-skid device. For example, the patent document with publication number CN212890284U discloses a portable anti-skid anti-skid device for automobiles, comprising a base plate (1) for contacting the ground, a panel (2) rotatably connected to the base plate (1) component and for contacting the automobile tire, and a support component (3) for supporting the panel (2). A first fixed plate (5) is fixed to the upper end face of the panel (2) at one end away from the rotation connection point and at both side edges thereof, perpendicular to the upper end face; a second fixed plate (6) is fixed to the lower end face of the base plate (1) at one end away from the rotation connection point and at both side edges thereof, perpendicular to the lower end face; the support component (3) comprises two rotating rods (31) symmetrically distributed on both sides of the panel (2) and rotatably connected to the panel (2), two support rods (32) respectively fixed to the side walls of the two rotating shafts, and a limiting rod (33) at both ends of which are fixed to the ends of the two support plates away from the rotating shafts. The backstop has defects during use: 1. To facilitate the removal of the backstop, an extension plate 8 and a through-slot 9 are provided on the bottom plate, which complicates the overall structure of the backstop and increases production costs. 2. The rotating rod 31 is directly connected to the through-hole on the first fixed plate 5. Under this structure, the force exerted on the panel 2 is transmitted to the support rod 32 through the rotating rod. The rotating rod and the support rod are perpendicular to each other and there is only partial contact between the rotating rod and the first fixed plate. Therefore, the rotating rod is easily deformed relative to the support rod, affecting the rotation function of the support assembly 3. Therefore, the backstop structure needs further improvement.

[0025] Combine Figures 1 to 5 The utility model of the automobile backstop is further described.

[0026] A vehicle backstop is characterized by comprising a base plate 2, a panel 1 and a support frame 3.

[0027] The first end of the panel 1 is pivotally connected to the first end of the base plate 2, allowing the second end of the panel 1 to rotate relative to the second end of the base plate 2. During this rotation, the panel 1 forms an open and closed position relative to the base plate 2. When in the closed position, the panel 1 covers the base plate 2, and an opening 4 is formed on the side of the panel 1 and base plate 2 corresponding to the second end. A pair of connecting grooves 14 are formed on the inner wall of the panel 1 near the second end, namely two connecting grooves 14 distributed on the left and right sides; the base plate 2 has a limiting wall 23 on its inner wall near the second end.

[0028] The support frame 3 comprises a bottom support rod 33, side support rods 32 located on both sides of the bottom support rod 33 and perpendicular to the bottom support rod 33, and a rotation rod 31 located on one end of the side support rod 32 facing away from the bottom support rod 33 and extending inward. The rotation rod 31 fits within the connection slot 14, and the shaft of the rotation rod 31 abuts against the inner wall of the panel 1. When the panel 1 and the bottom plate 2 are in the extended position, the bottom support rod 33 is supported on the bottom plate 2 and abuts against the limiting wall 23, providing support for the panel 1. When the panel 1 and the bottom plate 2 are in the closed position, the bottom support rod 33 can be rotated through the opening 4 to the outside of the panel 1 and the bottom plate 2 for the user to grasp.

[0029] The rotational connection structure between the panel 1 and the base plate 2 is as follows: the panel 1 has outer walls 11 on the left and right sides, and the base plate 2 has inner walls 22 on the left and right sides and one side corresponding to the second end. The outer wall 11 has an inwardly concave circular connecting portion 16 at a position close to the first end, and the inner wall 22 has a connecting hole 21 for the connecting portion 16 to cooperate with the connecting portion 16 at a position close to the first end. The connecting portion 16 can rotate in the connecting hole 21 to realize the rotational connection of the panel 1 on the base plate 2.

[0030] The panel 1 is an arc-shaped plate, that is, the first end and the second end of the panel 1 are bent away from the bottom plate 2. This structure can make the shape of the panel 1 adapt to the shape of the car tire, so that the first end of the panel 1 can extend to the bottom of the tire, avoiding the problem of the backstop moving backward and achieving an effective thrust effect.

[0031] Secondly, when the panel 1 is in a closed position relative to the base plate 2, the center position of the panel 1 rests against the inner wall 22, so that the second end of the panel 1 is away from the inner wall 22 on the second end of the base plate 2, thereby forming an opening 4, so that the bottom support rod 33 and part of the side support rod 32 of the support frame 3 are moved to the outside for the user to hold.

[0032] Panel 1 has support points 13 and stop plates 15 at locations corresponding to connection slots 14. Connection slots 14 are formed by the support points 13, stop plates 15, and the inner wall of panel 1. This structure allows the shaft of the rotating rod 31, which fits within the connection slot 14, to rest directly against the inner wall of panel 1, increasing the support area with panel 1. This not only improves support stability but also prevents deformation of the rotating rod 31 relative to the side support rods 32.

[0033] The limiting plate 15 is formed by bending a local portion of the panel 1 inward. Specifically, a U-shaped cutout 12 is cut out of the panel 1, and then the portion of the panel corresponding to the cutout is bent toward the inner support point 13 to form the limiting plate 15, which has a simple structure.

[0034] The support point 13 is formed by an inward depression of a local portion of the panel 1. Similarly, a U-shaped cutout is cut into the panel 1, and then the portion of the panel 1 corresponding to the U-shaped cutout is squeezed inward and deformed so that the portion protrudes from the inner surface of the panel 1. This forms the support point 13 and constrains the rotating rod 31 within the limit plate 15.

[0035] The limiting wall 23 is formed by inwardly recessing a portion of the bottom plate 2. Similarly, two parallel straight cuts are cut into the bottom plate 2, and then the portion of the bottom plate 2 corresponding to the two cuts is squeezed inward so that the portion protrudes from the inner surface of the bottom plate 2. This forms the limiting wall 23 for the bottom support rod 33 to abut against, thus providing a stable structure.

[0036] When in use, the panel 1 is rotated open so that the bottom support rod 33 rests against the bottom plate 2 and the limiting wall 23, and then the panel 1 is snapped under the tire to achieve a thrust-stopping effect; when not in use, the panel 1 can be rotated in the opposite direction to cover the bottom plate 2. When the panel 1 and the bottom plate 2 are rotated relative to each other to the closed position, the support frame 3 can be rotated toward the first end of the panel 1 so that the support frame 3 is between the panel 1 and the bottom plate 2 for easy storage, or the support frame 3 can be rotated toward the second end of the panel 1 so that the bottom support rod 33 and the partial side support rod 32 of the support frame 3 extend to the outside through the opening 4 for the user to hold and facilitate carrying. It should be noted that there is a certain amount of friction between the connecting portion 16 and the connecting hole 21 and between the outer wall 11 and the inner wall 22. Therefore, when the user holds the bottom support rod 33 to carry the backstop, the panel 1 and the bottom plate 2 will not rotate relative to each other.
