Description

Technical Field

[0001] This utility model relates to the field of traffic safety facilities technology, specifically a parking lot anti-collision device. Background Technology

[0002] Parking lot bumper strips are traffic safety protection devices installed on sharp edges such as pillars and corners. They are mainly used to mitigate the impact of low-speed vehicle collisions, reducing vehicle damage and pillar structural damage. Traditional bumper strips are usually made of a single rubber material and are fixed to the pillar surface with adhesive. Their core function is to absorb some of the collision energy through the elastic deformation of the material.

[0003] Existing parking lot bollard anti-collision devices mostly use a single layer of rubber strips glued to the edge of the bollard. The core problem lies in the limitations of material elasticity and structural design. When a vehicle collides with the bollard at low speed, traditional rubber strips, due to insufficient material resilience (e.g., Shore hardness 65-75A), can only absorb about 40%-45% of the impact energy. The remaining energy is directly transferred to the vehicle body, resulting in sheet metal dents exceeding 3mm in depth. Furthermore, the rubber strips are prone to permanent deformation after repeated pressure, losing their continuous protective capability.

[0004] Therefore, in order to better protect vehicles, there is an urgent need to develop a collision protection device that can effectively absorb impact energy and prevent the vehicle body from suffering rigid deformation. Utility Model Content

[0005] The main objective of this invention is to provide a parking lot anti-collision device to at least solve the problem that the existing anti-collision strips have insufficient buffering capacity and cannot effectively protect vehicles.

[0006] To achieve the above objectives, this utility model provides a parking lot anti-collision device comprising: a plate and a plurality of flexible buffer components evenly spaced on the outer surface of the plate; the plate is an L-shaped strip structure to fit the edge of the parking lot column; and a lattice reflective film is provided at the intervals of the plurality of flexible buffer components on the plate.

[0007] Furthermore, multiple flexible buffer components are detachably mounted on the plate.

[0008] Furthermore, the flexible cushioning component includes a cushioning pad and a slot with an opening at one end. The slot is disposed on the plate body, and the cushioning pad is provided with a limiting plate that matches the slot so that the cushioning pad is installed on the plate body with the cooperation of the limiting plate and the slot.

[0009] Furthermore, the opening of the card slot faces vertically upward.

[0010] Furthermore, the flexible buffer component is projected onto the mounting surface of the plate as a parallelogram, and multiple lattice reflective films are adapted to be installed at the intervals of the parallelograms formed by the multiple flexible buffer components.

[0011] Furthermore, the outer surface of the flexible buffer component is curved.

[0012] Furthermore, the plate is provided with multiple screws, and multiple screw holes are arranged in pairs at the four corners of the plate so that the plate can be fixed to the column by expansion bolts.

[0013] The parking lot anti-collision device using this utility model includes: a plate and multiple flexible buffer components evenly spaced on the outer surface of the plate. The plate is an L-shaped strip structure to fit snugly against the edges of the parking lot pillars. A lattice reflective film is provided at the intervals between the flexible buffer components. This utility model, through the rigid support structure of the L-shaped plate and its tight fit against the pillar edges, disperses the impact force generated by a vehicle collision from the corners to both sides of the pillar, effectively reducing local pressure. Simultaneously, the evenly distributed flexible buffer components on the plate surface form a gradient energy-absorbing band, absorbing and dissipating impact energy layer by layer at the moment of collision, reducing the depth of the body panel dent. Combined with the high-reflectivity lattice reflective film embedded at the intervals of the flexible buffer components, it achieves long-distance optical warnings of over 30 meters in low-light environments, guiding drivers to avoid collisions in advance. Ultimately, through the synergistic effect of rigid dispersion, flexible energy absorption, and optical warning, it solves the problem of vehicle damage caused by insufficient buffering capacity of anti-collision strips in parking lot scenarios.

[0022] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0023] This utility model discloses a parking lot anti-collision device, such as... Figures 1 to 5 As shown, the invention includes a plate 10 and multiple flexible buffer components 20 evenly spaced on the outer surface of the plate 10. The plate 10 is an L-shaped strip structure to fit snugly against the edges of parking lot pillars. A lattice reflective film 30 is provided at the intervals between the flexible buffer components 20. This invention, through the rigid support structure of the L-shaped plate 10 and its close fit against the pillar edges, disperses the impact force generated by a vehicle collision from the corners to both sides of the pillar, effectively reducing local pressure. Simultaneously, the evenly distributed flexible buffer components 20 on the surface of the plate 10 form a gradient energy absorption band, absorbing and dissipating impact energy layer by layer at the moment of impact, reducing the depth of the body panel dent. Combined with the high-reflectivity lattice reflective film 30 embedded at the intervals of the flexible buffer components 20, it achieves long-distance optical warnings of over 30 meters in low-light environments, guiding drivers to avoid collisions in advance. Ultimately, through the synergistic effect of rigid dispersion, flexible energy absorption, and optical warning, it solves the problem of vehicle damage caused by insufficient buffering capacity of anti-collision strips in parking lot scenarios.

[0024] Based on the above design, in one optional embodiment, the flexible buffer component 20 is fixedly mounted on the outer surface of the plate 10. This design satisfies the buffering requirement and enhances the stability of the flexible buffer component 20, preventing it from detaching from the plate 10 during impact. However, during long-term use, it was found that the flexible buffer component 20 in this embodiment is difficult to maintain. If the wear is severe, the plate 10 needs to be removed as well, which is not only time-consuming and labor-intensive but also wastes the material of the plate 10 and damages the wall surface of the parking lot column. Therefore, in a more preferred embodiment, multiple flexible buffer components 20 are detachably mounted on the plate 10. Workers only need to disassemble and replace the damaged flexible buffer component 20 without disassembling the entire plate 10, reducing the difficulty of operation and protecting the wall structure.

[0025] In one optional embodiment, the flexible buffer component 20 is installed and removed from the plate 10 using a strong hook and loop fastener, which is very simple and reduces costs. However, due to the diverse environments of parking lots, some outdoor parking lots are prone to dust, and the surface of the hook and loop fastener is easily contaminated with dust or rainwater, thus reducing the adhesion strength. To avoid this, in a preferred embodiment, the flexible buffer component 20 includes a buffer pad 21 and a slot 22 with an opening at one end. The slot 22 is disposed on the plate 10, and the opening of the slot 22 is T-shaped. The buffer pad 21 is provided with a limiting plate 211 that matches the slot 22 so that the buffer pad 21 is installed on the plate 10 with the cooperation of the limiting plate 211 and the slot 22. With this design, the buffer pad 21 can be inserted into the slot 22 and fixed on the plate 10, avoiding the adverse effects caused by environmental changes.

[0026] In one optional embodiment, the opening of the slot 22 is horizontal, which facilitates installation by the staff. The buffer pad 21 can be installed simply by aligning the limiting plate 211 with the opening of the slot 22 and pushing it in, which greatly reduces the difficulty of installation. However, since the scraping that occurs during vehicle operation is also horizontal relative to the pillar, in some cases the vehicle body may easily pull the buffer pad 21 out of the slot 22, affecting the anti-collision effect. Therefore, in a preferred embodiment, the opening of the slot 22 is vertically upward, which avoids the situation where the friction of the vehicle body surface pulls the buffer pad 21 out of the slot 22 when the vehicle scrapes.

[0027] The above-described design significantly improves the buffering capacity of the anti-collision device; however, the protruding flexible buffer component 20 may sometimes obstruct the lattice reflective film 30 at the intervals, such as... Figure 2 As shown; to avoid this situation, in a preferred embodiment, the flexible buffer component 20 is a parallelogram projected onto the mounting surface of the plate 10, and multiple lattice reflective films 30 are obliquely installed at the intervals of the parallelograms formed by the multiple flexible buffer components 20. The oblique placement optimizes the light reflection path, and by utilizing the principle of retroreflection, the glass microspheres or microprisms on the surface of the reflective strip can be directionally reflected into the driver's field of vision when illuminated by a light source, significantly improving the nighttime recognition distance. Experiments show that the oblique design can increase the effective recognition distance by 30%-50%. Secondly, the oblique angle can cover a wider dynamic observation range, avoiding blind spots caused by viewing angle shifts in the vertical plane, ensuring multi-directional warning effects when vehicles turn or pedestrians approach from the side. Furthermore, the oblique design disperses direct glare from strong light sources, such as sunlight or oncoming headlights, through asymmetrical reflection, reducing the risk of driver glare.

[0028] Furthermore, such as Figures 1 to 5As shown, the outer surface of the flexible buffer component 20 is curved. When the car does not directly collide with the anti-collision device, but only slightly grazes it, the curved flexible buffer component 20 can reduce contact with the car body, thereby reducing friction.

[0029] In one embodiment, the plate 10 can be fixed to the column by applying strong adhesive to the inner surface of the plate; however, if the outer surface of the column itself is not strong enough, and issues such as plaster peeling occur, the plate 10 cannot be effectively fixed; therefore, in a preferred embodiment, such as Figures 1 to 5 As shown, the plate 10 is provided with a plurality of screw holes 11, which are arranged in pairs at the four corners of the plate 10 so that the plate 10 can be fixed to the column by expansion bolts, thereby enhancing stability.

[0030] In practical use, the staff uses expansion bolts to fix the plate 10 to the edge of the column. Then, the limiting plate 211 on the buffer pad 21 is aligned with the upper opening of the slot 22. Multiple buffer pads 21 are installed into the slot 22 from bottom to top. After verification, the installation is completed. After a period of use, if some buffer pads 21 are found to be severely worn, the staff can push the buffer pads 21 upwards, remove the damaged buffer pads 21, and install the new buffer pads 21 in the aforementioned manner to complete the replacement of the buffer pads 21.

[0031] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
