Description

Technical Field

[0001] The utility model relates to the field of anti-collision buffer vehicles, in particular to an anti-collision pad and an anti-collision buffer vehicle. Background Art

[0002] The anti-collision buffer vehicle is mainly used for highway construction, tunnel construction, and road construction. It minimizes the safety risks of construction vehicles, maintenance personnel, and accident handling traffic police in the maintenance and construction of urban roads and highways. The anti-collision buffer energy absorption module of the anti-collision buffer vehicle is mainly composed of a vehicle-mounted anti-collision buffer pad and a guide sign frame, which acts as a buffer guard behind the construction vehicle. If a rear-end collision occurs, a buffer area can be constructed between the vehicle in the accident and the construction area in front. The energy of the impact is absorbed by the deformation of the machine structure, minimizing the probability of collision of the protected personnel and equipment. Chinese patent: CN220076316U discloses a vehicle-mounted anti-collision pad, which relates to the field of anti-collision pad technology. It includes an anti-collision plate, a rubber protective pad and a second buffer pad. The top of the anti-collision plate is fixedly provided with a rubber protective pad, the bottom of the anti-collision plate is fixedly provided with a first buffer pad, both sides of the top of the anti-collision plate are fixedly provided with distance sensors, both sides of the anti-collision plate are fixedly provided with side panels, the top of the side panels is provided with a mounting groove, and the inner wall of the mounting groove is movably provided with a connecting seat, and the top of the connecting seat is fixedly provided with a monitoring camera. By setting a card block, the bidirectional screw rod is driven to rotate by rotating the hand wheel, and the bidirectional screw rod in the rotating state drives the card blocks on both sides to move through the nut seat. When one end of the card block is out of the card slot on the connecting seat, the card connection of the connecting seat can be released, and then the monitoring camera can be disassembled, so as to facilitate the maintenance of the monitoring camera.

[0003] However, the above scheme still has certain defects. The inventors have found through research that most of the existing vehicle-mounted anti-collision structures adopt the anti-collision structure in the above scheme, which achieves the purpose of anti-collision by setting two parallel distributed pads and arranging a number of elastic parts between the pads to buffer the impact force. However, the elastic buffer such as the shock absorber has a fixed expansion and contraction direction, which will cause the two pads to be able to move only in the expansion and contraction direction of the buffer. When the impact direction and the expansion and contraction direction of the buffer have a certain offset angle, the buffering energy absorption effect of the buffer will be relatively reduced, and the buffering performance will decrease more significantly as the angle offset increases.

[0004] How to invent a crash cushion and a crash buffer car to improve these problems has become an urgent problem to be solved by those skilled in the art. Utility Model Content

[0005] To make up for the above deficiencies, the present utility model provides an anti-collision pad and an anti-collision buffer vehicle, aiming to improve the problem that most of the existing vehicle-mounted anti-collision structures adopt two parallelly distributed cushion plates, and a number of elastic members are arranged between the cushion plates to buffer the impact force for anti-collision purposes. However, for elastic buffer members such as shock absorbers, their telescopic directions are fixed, which will cause the two cushion plates to only displace in the telescopic direction of the buffer member. When the impact direction has a certain offset angle with the telescopic direction of the buffer member, the buffer energy absorption effect of the buffer member will be relatively reduced, and the buffer performance will decrease more significantly as the angle offset increases.

[0006] In a first aspect, the present utility model provides an anti-collision pad, which includes an inner mounting hemispherical shell. On one side of the inner mounting hemispherical shell, an outer force-bearing hemispherical shell is coaxially arranged. On the surface of the inner mounting hemispherical shell away from the outer force-bearing hemispherical shell, a cylindrical structure extends outward. A multi-angle connection mechanism is slidably connected inside the cylindrical structure. The multi-angle connection mechanism includes a rotating rod. The rotating rod extends through a through groove provided on the outer wall of the inner mounting hemispherical shell to the space between the inner mounting hemispherical shell and the multi-angle connection mechanism and is rotatably connected with a connecting member. One end of the connecting member is fixedly connected to the inner wall of the outer force-bearing hemispherical shell. The other end of the rotating rod is rotatably connected to a horizontal buffer mechanism. A number of elastic buffer members are connected between the outer wall of the inner mounting hemispherical shell and the inner wall of the outer force-bearing hemispherical shell.

[0007] In a preferred technical solution of the present utility model, a number of mounting parts are uniformly arranged in a ring on the outer circumferential wall of the cylindrical structure.

[0008] In a preferred technical solution of the present utility model, a number of elastic buffer members are uniformly distributed at positions that fit the outer wall structure of the inner mounting hemispherical shell.

[0009] In a preferred technical solution of the present utility model, a protective rubber pad with a corresponding shape structure is arranged on the outer wall of the outer force-bearing hemispherical shell.

[0010] In a preferred technical solution of the present utility model, the horizontal buffer mechanism includes two vertically parallelly distributed sliding rods. Both ends of each sliding rod are respectively slidably connected in corresponding sliding grooves. The four sliding grooves are respectively opened on the inner walls of the upper and lower sides of the cylindrical structure. One end of the rotating rod is rotatably connected between the opposite surfaces of the two sliding rods. The upper and lower ends of the two sliding rods are fixedly connected by connecting plates. One side surface of each connecting plate is fixedly connected to one end of a telescopic rod. The other end of each telescopic rod is fixedly connected to one side surface of a corresponding mounting plate. The two mounting plates are respectively arranged on the inner walls of the upper and lower sides of the cylindrical structure. Both ends of a spring are respectively fixedly connected to one side surface of each mounting plate and one side surface of the corresponding connecting plate. Each spring is sleeved outside the corresponding telescopic rod.

[0011] In a preferred technical solution of the present utility model, one end of each universal ball bearing is fixedly connected to both ends of each elastic buffer member, and the other end of each said universal ball bearing is fixedly connected to the outer wall of the inner mounting hemispherical shell and the inner wall of the outer force-bearing hemispherical shell respectively.

[0012] In a preferred technical solution of the present utility model, each said elastic buffer member is a shock absorber.

[0013] In a second aspect, the present utility model further provides a collision buffer vehicle, including the collision cushion described above.

[0014] The beneficial effects of the present utility model are as follows: A collision cushion and a collision buffer vehicle obtained by the above design of the present utility model, when in use, by connecting a force-bearing outer hemispherical shell that can rotate in multiple directions on one side of the inner mounting hemispherical shell by means of a multi-angle connection mechanism, and evenly distributing and arranging a plurality of elastic buffer members between the outer wall of the inner mounting hemispherical shell and the inner wall of the force-bearing outer hemispherical shell to further connect and support the two, so that when the impact direction has an inclination angle relative to the horizontal direction, the force-bearing outer hemispherical shell will rotate independently relative to the inner mounting hemispherical shell to accommodate the impact angle. At this time, the elastic buffer members in the corresponding area will be compressed to buffer the impact force, thus avoiding the situation where the buffering effect of the elastic buffer members will decrease when the impact direction has a certain angle with the extension direction of the elastic buffer members.

Specific embodiments

[0022] To make the purpose, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1 to 5 , the present utility model provides a technical solution: an anti-collision pad, including an inner hemispherical shell 1 for installation, an outer hemispherical shell 3 under stress is coaxially arranged on one side of the inner hemispherical shell 1 for installation, a cylindrical structure extends outward on the surface of the inner hemispherical shell 1 for installation away from the outer hemispherical shell 3 under stress, and a multi-angle connection mechanism 2 is slidably connected inside the cylindrical structure. The multi-angle connection mechanism 2 includes a rotating rod 201. The rotating rod 201 extends between the inner hemispherical shell 1 for installation and the multi-angle connection mechanism 2 through a through slot 101 provided on the outer wall of the inner hemispherical shell 1 for installation and is rotatably connected with a connecting piece 202. One end of the connecting piece 202 is fixedly connected to the inner wall of the outer hemispherical shell 3 under stress, and the other end of the rotating rod 201 is rotatably connected to the horizontal buffer mechanism. A plurality of elastic buffers 4 are connected between the outer wall of the inner hemispherical shell 1 for installation and the inner wall of the outer hemispherical shell 3 under stress.

[0024] Please refer to Figure 3 and Figure 4 , a plurality of installation parts 102 are evenly arranged in a ring on the outer circumferential wall of the cylindrical structure.

[0025] By providing a plurality of installation parts 102 on the outer wall of the inner hemispherical shell 1 for installation, the whole anti-collision pad can be installed or connected to other devices, thereby reducing the limitations during use.

[0026] Furthermore, a plurality of elastic buffers 4 are evenly distributed at positions that fit the outer wall structure of the inner hemispherical shell 1 for installation.

[0027] The installed inner hemispherical shell 1 and the force-bearing outer hemispherical shell 3 are arranged with the same center of the sphere. One end of each elastic buffer 4 points to the center position of the installed inner hemispherical shell 1 and the force-bearing outer hemispherical shell 3. Adjust the elastic coefficient of each elastic buffer 4 according to its support extension direction and distribution position, so that the force-bearing outer hemispherical shell 3 can always be distributed on the same horizontal axis as the installed inner hemispherical shell 1 when it is in a static and unloaded state without affecting the buffering effect.

[0028] Furthermore, a protective rubber pad with a corresponding shape structure is arranged on the outer wall of the force-bearing outer hemispherical shell 3.

[0029] By arranging a protective rubber pad on the outer wall of the force-bearing outer hemispherical shell 3, the absorption of the impact force can be further improved, so as to achieve the purpose of enhancing the buffering effect.

[0030] Furthermore, the horizontal buffer mechanism includes two vertically parallel sliding rods 203. Both ends of each sliding rod 203 are slidably connected to the corresponding sliding grooves 204 respectively. The four sliding grooves 204 are respectively opened on the inner walls of the upper and lower sides of the cylindrical structure. One end of the rotating rod 201 is rotatably connected between the opposite surfaces of the two sliding rods 203. The upper and lower ends of the two sliding rods 203 are fixedly connected through connecting plates 205. One end of a telescopic rod 206 is fixedly connected to one side surface of each connecting plate 205. The other end of each telescopic rod 206 is fixedly connected to one side surface of the corresponding mounting plate 208. The two mounting plates 208 are respectively arranged on the inner walls of the upper and lower sides of the cylindrical structure. Both ends of a spring 209 are respectively fixedly connected to one side surface of the corresponding mounting plate 208 and one side surface of the corresponding connecting plate 205. Each spring 209 is sleeved outside the corresponding telescopic rod 206.

[0031] When the outer hemispherical shell 3 under force is impacted in the horizontal direction, since the outer hemispherical shell 3 under force is connected to one end of the rotating rod 201 through the connecting member 202, and the other end of the rotating rod 201 is connected to two sliding rods 203, the two sliding rods 203 are fixedly connected through the connecting plates 205 at the upper and lower ends and are simultaneously slidably installed in the corresponding sliding grooves 204, so the horizontal impact force will drive the outer hemispherical shell 3 under force to translate towards the side of the inner hemispherical shell 1 installed, thereby driving the two sliding rods 203 to perform synchronous sliding displacements through the rotating rod 201. The two connecting plates 205 are respectively connected to the corresponding mounting plates 208 through the telescopic rods 206, and a spring 209 is arranged outside the telescopic rod 206. The spring 209 will buffer the acting force generated by the impact. When the impact direction has an inclination angle relative to the horizontal direction, one end of the rotating rod 201 is rotatably installed between the two sliding rods 203, so the rotating rod 201 can rotate in the vertical direction, and one end of the rotating rod 201 is also rotatably connected to the connecting member 202, so the connecting member 202 can rotate independently in the horizontal direction relative to the rotating rod 201. Therefore, when the impact direction has an inclination angle relative to the horizontal direction, the outer hemispherical shell 3 under force will rotate independently relative to the inner hemispherical shell 1 to conform to the impact angle. At this time, the elastic buffer member 4 in the corresponding area will be compressed to buffer the impact acting force, thereby avoiding the situation that the buffering effect of the elastic buffer member 4 will decrease when the impact direction has a certain angle with the extending direction of the elastic buffer member 4.

[0032] Please refer to Figure 5 , one end of each universal ball bearing 402 is fixedly connected to both ends of each elastic buffer member 4, and the other end of each universal ball bearing 402 is fixedly connected to the outer wall of the inner hemispherical shell 1 installed and the inner wall of the outer hemispherical shell 3 under force respectively.

[0033] Both ends of each elastic buffer member 4 are rotatably connected to the outer wall of the inner hemispherical shell 1 installed and the outer wall of the outer hemispherical shell 3 under force respectively through the universal ball bearings 402, so that in the static state, the influence of gravity on the outer hemispherical shell 3 under force can be offset under the action of different elastic support forces of itself, so that each elastic buffer member 4 can maintain a predetermined extending direction to support the outer hemispherical shell 3 under force. When the outer hemispherical shell 3 under force rotates and deflects due to an external impact, all the elastic buffer members 4 can rotate correspondingly in cooperation with the deflection direction of the outer hemispherical shell 3 under force, buffer the impact force while continuing to support the outer hemispherical shell 3 under force, and can share and offset the corresponding impact acting forces according to their respective positions and angles, improving the overall buffering effect.

[0034] Furthermore, each elastic buffer member 4 is a shock absorber 401.

[0035] In actual use, in addition to the shock absorber 401, other components with elastic telescopic buffering functions can also be used.

[0036] Working principle: The anti-collision pad is integrally installed and connected to the rear of the anti-collision buffer vehicle through the installation part 102. Multiple evenly distributed anti-collision pads can be installed according to actual situations to increase the protection area. When the force-bearing outer hemispherical shell 3 is impacted in the horizontal direction, the horizontal impact force will drive the force-bearing outer hemispherical shell 3 to translate towards the installation inner hemispherical shell 1 side, thereby driving the two sliding rods 203 to perform synchronous sliding displacements through the rotating rod 201. The two connecting plates 205 are respectively connected to the corresponding mounting plates 208 through the telescopic rods 206, and a spring 209 is arranged outside the telescopic rod 206. The spring 209 will buffer the acting force generated by the impact. When the impact direction has an inclination angle relative to the horizontal direction, one end of the rotating rod 201 is rotatably installed between the two sliding rods 203, so the rotating rod 201 can rotate in the vertical direction. One end of the rotating rod 201 is also rotatably connected to the connecting piece 202, so the connecting piece 202 can rotate independently in the horizontal direction relative to the rotating rod 201. The force-bearing outer hemispherical shell 3 will rotate independently relative to the installation inner hemispherical shell 1 to meet the impact angle. At this time, the elastic buffer member 4 in the corresponding area will be compressed to buffer the impact acting force, thereby avoiding the situation where the buffering effect of the elastic buffer member 4 will decrease when the impact direction has a certain angle with the extension direction of the elastic buffer member 4.

[0037] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
