Description

Technical Field

[0001] The invention relates to the field of emergency parking, in particular to a movable emergency parking device. Background Art

[0002] The number of motor vehicles is huge and growing rapidly. If a car running at high speed encounters brake failure, it is extremely dangerous, often resulting in car crashes and deaths, and even chain reactions that cause large-scale damage accidents. Although emergency parking strips can control cars, they are subject to many conditions and cannot be built at will. They are generally only available on special sections of highways, and emergency parking strips cannot be found at any time when brake failure occurs. If a car on an urban road encounters brake failure at a high speed, there is no place to stop in an emergency. It can only find an energy dissipation bag to collide with, or find a relatively solid place to collide with, which is difficult to control and has serious consequences. Summary of the invention

[0003] The purpose of the present invention is to solve the above-mentioned problems in the prior art and to provide a movable emergency parking device, which can reduce or even avoid the loss of life and property caused by brake failure.

[0004] In order to achieve the above object, the present invention adopts the following technical scheme:

[0005] A movable emergency parking device includes a brake pad, a bridge, a retaining wall, and a universal wheel mechanism, wherein the brake pad has a certain thickness, one end of the bridge is connected to the upper surface of one end of the brake pad so that the bridge is at a certain height from the ground, and the other end of the bridge is horizontally connected to the retaining wall. The universal wheel mechanism is arranged in front of the retaining wall, wherein the width of the brake pad is not less than the width of the rear wheels of the car so that the rear wheels of the car can be completely pressed on the brake pad, and the width of the bridge is less than the width of the front wheels of the car so that the front wheels of the car can turn freely after passing the brake pad and returning to the road surface.

[0006] A plurality of friction rods are arranged at the bottom of the brake plate.

[0007] The friction rod is made of a material with large friction resistance, wear resistance, heat resistance and low noise.

[0008] The friction rod is made of cast aluminum material.

[0009] The present invention also includes running wheels, and at least two running wheels are provided, which are detachably arranged on both sides of the brake plate.

[0010] The universal wheel mechanism is provided with a traction ring.

[0011] Compared with the prior art, the technical solution of the present invention has the following beneficial effects:

[0012] The present invention is provided with a brake plate, a bridge, a retaining wall and a universal wheel mechanism. Through the cooperation and action of the four, when a car with brake failure rushes onto the movable emergency parking device, the bumper in front of the car hits the retaining wall, and the brake plate is dragged forward through the bridge. The brake plate is pressed to the ground by the rear wheel of the car, and a large friction surface is generated with the ground, forming a strong friction force, forcing the car to stop quickly. After the car rushes up, the front wheel continues to stay in front of the road surface, and the forward direction can continue to be controlled. The front end of the retaining wall is a free universal wheel mechanism, which can flexibly rotate in the direction of the car, so that the front obstacles can be avoided before the brake stops, and the accident is prevented from expanding.

[0013] The present invention provides a plurality of friction rods at the bottom of the brake plate, through which a large friction force can be generated, and the heat generated by the friction can be quickly diffused, thereby reducing the temperature rise, and at the same time, the damage to the road surface and the friction sound can be reduced.

[0014] The present invention can provide multiple types of movable emergency parking devices according to vehicle models of different sizes to meet the needs of different vehicle models and has a wide range of applications.

[0015] The invention is provided with a traction ring and traveling wheels, and can be placed at a required place at any time by traction according to the needs, and a reminder sign can be erected at a suitable distance. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and more understandable, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0024] like Figures 1 to 6 As shown, the movable emergency parking device of this embodiment includes a brake plate 1, a bridge frame 2, a retaining wall 3, and a universal wheel mechanism 4;

[0025] The brake plate 1 has a certain thickness, one end of the bridge frame 2 is connected to the upper surface of one end of the brake plate 1 so that the bridge frame 2 has a certain height from the ground, the other end of the bridge frame 2 is horizontally connected to the retaining wall 3, and the universal wheel mechanism 4 is arranged in front of the retaining wall 3.

[0026] The width of the brake plate 1 is not less than the width of the rear wheels of the car, so as to ensure that the rear wheels on both sides of the car are completely pressed on the brake plate 1, so that the brake plate 1 and the ground generate strong friction;

[0027] The bridge frame 2 must ensure that the strong impact force of the car is transmitted to the brake plate 1, so it needs to be strong and reliable enough. The width of the bridge frame 2 is smaller than the width of the front wheels of the car, so that the front wheels of the car can turn freely after passing the brake plate 1 and returning to the road surface, thereby allowing the car to control the direction before stopping and avoid obstacles in front.

[0028] The retaining wall 3 needs to withstand the impact of the car, and on the one hand needs to be strong enough, and on the other hand needs to have a good enough buffering effect to minimize the impact damage to the car. Therefore, the retaining wall 3 can be made of a material with buffering performance.

[0029] like Figure 4 As shown, the bottom of the brake plate 1 is provided with a plurality of friction rods 5, which are fixed to the bottom of the brake plate 1 by screws. The friction rods 5 are made of a material with large friction resistance, wear resistance, heat resistance and low noise, such as cast aluminum. The friction rods 5 can generate a large friction force, and the heat generated by friction can be quickly diffused to reduce the temperature rise, while reducing the damage to the road surface and the friction sound.

[0030] In order to facilitate towing and moving, a towing ring 6 is provided on the universal wheel mechanism 4, which can be towed to the required position by a towing vehicle. Fixing screw holes 8 for installing running wheels 7 are provided on both sides of the brake plate 1. When towing and moving is required, the running wheels 7 are fixed to the fixing screw holes 8 on both sides of the brake plate 1, so that the brake plate 1 is lifted off the ground and can be smoothly towed to the required place, such as Figure 6 After being placed in place, remove the running wheel 7, as shown in FIG. Figure 5 As shown, a warning sign may also be erected at an appropriate distance.

[0031] The installation and use method of the present invention is as follows:

[0032] 1. Select the brake plate 1 according to the size of the selected vehicle model, install the matching friction rod 5 at the bottom of the brake plate 1, and fix it with screws;

[0033] 2. Screw the matching bridge frame 2 onto the brake plate 1, then install the matching retaining wall 3, and then install the universal wheel mechanism 4 before use.

[0034] 3. Install the travel wheels 7 on the fixing screw holes 8 on both sides of the brake plate 1. The tractor can place the movable emergency parking device to the required position through the traction ring 6, and then remove the travel wheels 7.

[0035] The principle of the present invention is as follows:

[0036] like Figure 1 As shown, after a car with brake failure in driving rushes onto the movable emergency parking device, the bumper in front of the car hits the retaining wall 3 of the movable emergency parking device, and the brake plate 1 is dragged forward through the bridge frame 2. The brake plate 1 is pressed against the ground by the rear wheels of the car, and a large friction surface is generated with the ground, forming a strong friction force, forcing the car to stop quickly. After the car rushes up, the front wheels continue to stay in front of the road surface and can continue to control the forward direction. The front end of the movable emergency parking device is a free universal wheel mechanism 4, which can flexibly rotate in the direction of the car, so that the front obstacles can be avoided before the brake stops, and the accident can be prevented from expanding.
