Detailed Description

Other advantages and effects of the present invention will become apparent to those skilled in the art from the following disclosure, which describes the embodiments of the present invention with reference to specific examples. The invention may be practiced or carried out in other embodiments that depart from the specific details, and the details of the present description may be modified or varied from the spirit and scope of the present invention. It should be noted that the following embodiments and features in the embodiments may be combined with each other without conflict. It is also to be understood that the terminology used in the examples of the invention is for the purpose of describing particular embodiments only, and is not intended to limit the scope of the invention. The test methods in the following examples, in which specific conditions are not noted, are generally conducted under conventional conditions or under conditions recommended by the respective manufacturers.

Please refer to fig. 1 to 6. It should be understood that the structures, proportions, sizes, etc. shown in the drawings are for illustration purposes only and should not be construed as limiting the invention to the extent that it can be practiced, since modifications, changes in the proportions, or adjustments of the sizes, which are otherwise, used in the practice of the invention, are included in the spirit and scope of the invention which is otherwise, without departing from the spirit or scope thereof.

Referring to fig. 1, the present invention provides an anti-collision vehicle, which can effectively solve the problems of poor protection performance and difficulty in effectively absorbing kinetic energy generated by collision of the existing anti-collision vehicle. When a rear-end collision accident occurs, the anti-collision vehicle can construct a buffer area between the accident vehicle and the front construction operation area, and the deformation of the machine structure is used for absorbing the collision energy, so that the collision probability of protected personnel and equipment is reduced to the greatest extent. Specifically, the crashworthy car may include a car body 10 and a cushioning device 20, wherein the cushioning device 20 is attached to the tail of the car body 10. Therefore, the energy absorbing effect of the anti-collision vehicle can be effectively improved by the buffer device 20.

Referring to fig. 1 and 2, in an embodiment, the buffer device 20 may include a base 100, a first buffer module, a second buffer module, a third buffer module, and a protection component. Wherein the base 100 and the vehicle body 10 are connected, and a lifting assembly 50 is also allowed to be provided between the base 100 and the vehicle body 10. The height position of the buffer device 20 relative to the vehicle body 10 can be adjusted by the lifting assembly 50, so that the actual buffer effect of the device is improved. It should be noted that the first buffer module, the second buffer module and the third buffer module are sequentially connected, and the first buffer module is connected to the base 100. Therefore, the first buffer module, the second buffer module and the third buffer module are sequentially connected, so that the buffer device 20 can absorb energy in multiple stages. The protection component is fixedly connected with the base 100, and a closed area is defined by the protection component and the base 100. Thus, the first, second, and third buffer modules may be allowed to reside in the enclosed area enclosed by the guard assembly and base 100. The protection component can avoid the first buffer module, the second buffer module and the third buffer module being directly exposed in the external environment, and can provide a certain buffer force to improve the practical use effect of the buffer device 20.

Referring to FIG. 2, in one embodiment, the first cushion module may include a cushion plate 105, at least one set of linkage assemblies, and a cushion spring 104. The buffer plate 105 is disposed on one side of the base 100, and the buffer plate 105 and the base 100 are disposed in parallel. The link assembly is located between the buffer plate 105 and the base 100, and the link assembly is used to connect the buffer plate 105 and the base 100 to each other. A plurality of sliding grooves 106 may be provided on the buffer plate 105, and sliding blocks 107 may be slidably connected to the sliding grooves 106. In particular, the connecting rod assemblies may be allowed to be provided with a plurality of groups, and the plurality of groups of connecting rod assemblies are arranged in parallel. In the present embodiment, the link assembly is provided with two groups, but is not limited thereto, and determination according to actual demands may be allowed. It should be noted that the link assembly may include two buffer rods 103, and the two buffer rods 103 are symmetrically disposed. Wherein one end of the buffer rod 103 is located on the base 100, and the buffer rod 103 is allowed to rotate relative to the base 100. The other end of the buffer rod 103 is located on the buffer plate 105, and the other end of the buffer rod 103 may be allowed to hinge on the slider 107. Because the sliding connection between the slider 107 and the cushion plate 105 is provided, when the cushion plate 105 is pressed by the front surface, the slider 107 can be driven to slide relative to the cushion plate 105 to adjust the distance between the cushion plate 105 and the base 100. The buffer spring 104 is located between the buffer rod 103 and the base 100, one end of the buffer spring 104 is fixedly connected with the buffer rod 103, and the other end is fixedly connected with the base 100. Accordingly, when the distance between the buffer plate 105 and the base 100 is changed, the buffer rod 103 compresses the buffer spring 104. Therefore, the buffer spring 104 can absorb the kinetic energy received by the buffer plate 105, so as to improve the actual buffering effect of the buffer device 20.

It should be noted that, in order to enhance the practical use effect of the present device, the first cushioning module is capable of providing corresponding cushioning and energy absorption when the cushioning plate 105 is impacted laterally. In an embodiment, the adjustment block 101 may be allowed to be slidably coupled to the base 100, and the adjustment springs 102 may be provided at both ends of the adjustment block 101. One end of the adjusting spring 102 is fixedly connected with the adjusting block 101, and the other end of the adjusting spring 102 is fixedly connected with the base 100. Thus, it is possible to allow the adjustment block 101 to be located at the center of the base 100 by the adjustment springs 102 located at both ends of the adjustment block 101. Wherein the other end of the buffer rod 103 may be allowed to hinge on said adjustment block 101. It should be noted that, in the present embodiment, the elastic direction of the adjusting spring 102 is perpendicular to the elastic direction of the buffer spring 104. Therefore, the elastic directions of the adjusting spring 102 and the buffer spring 104 are set to be perpendicular to each other, so that the buffer plate 105 can release the kinetic energy transmitted from a plurality of angles, so as to improve the actual energy absorption effect of the buffer device 20.

Referring to fig. 2 and 4, the second buffer module is located between the first buffer module and the third buffer module. Specifically, the second buffer module is directly connected to the buffer plate 105, and the second buffer module may allow for a multi-stage aluminum alloy thin film honeycomb structure. The second buffer module is of a multi-section aluminum alloy film honeycomb structure, so that kinetic energy generated by collision can be effectively absorbed by the second buffer module, and rebound of a collided vehicle can be avoided.

Referring to fig. 2, 4 and 5, the third buffer module is connected to the second buffer module, so that most of the energy generated by the impact can be absorbed by the third buffer module. It should be noted that, the third buffer modules may be allowed to be provided with multiple groups, and multiple groups of third buffer modules are sequentially connected. In particular, the third buffer module may include a connection plate 320 and a plurality of buffer frame assemblies 300, wherein the connection plate 320 may allow two sets to be provided, and the plurality of buffer frame assemblies 300 are located between the two connection plates 320. The connecting plate 320 located at one side of the third buffer module is fixedly connected with the second buffer module. The specific connection manner between the connection board 320 and the second buffer module may allow determination according to actual requirements. For example, the connection between the connection plate 320 and the second buffer module may be allowed to be performed by welding, but not limited thereto, and may be allowed to be determined according to actual requirements. It should be noted that the buffer frame assembly 300 may include a plurality of connecting rods 310, and the plurality of connecting rods 310 are fixedly connected. The connecting rod 310 may be a tubular structure, and the connecting rod 310 is made of aluminum alloy. By providing the connection rod 310 as a tubular structure of aluminum alloy, the strength of the buffer frame assembly 300 can be effectively improved, and the weight of the buffer frame assembly 300 can be reduced. Therefore, kinetic energy generated by the impact can be effectively absorbed by the shock absorber assembly 300. It should be noted that the specific connection manner between the plurality of connection rods 310 may allow for determination according to actual requirements. For example, in one embodiment, the connecting rod 310 may include a first connecting rod 311, a second connecting rod 312, a third connecting rod 313, a fourth connecting rod 314, and a fifth connecting rod 315. The first connecting rod 311 and the second connecting rod 312 are fixedly connected to one end of the third connecting rod 313, and the fourth connecting rod 314 and the fifth connecting rod 315 are fixedly connected to the other end of the third connecting rod 313. Specifically, the other ends of the first connecting rod 311, the second connecting rod 312, the fourth connecting rod 314 and the fifth connecting rod 315 are fixedly connected with the connecting plate 320 respectively. It should be noted that the adjacent included angle between the first connecting rod 311, the second connecting rod 312 and the third connecting rod 313 is 120 °, and the adjacent included angle between the third connecting rod 313, the fourth connecting rod 314 and the fifth connecting rod 315 is 120 °. Accordingly, by setting the adjacent included angles between the first, second and third connection bars 311, 312 and 313 to 120 °, and setting the adjacent included angles between the third, fourth and fifth connection bars 313, 314 and 315 to 120 °. The strength of the buffer frame assembly 300 can be ensured, and the energy absorbing effect of the first buffer assembly can be improved. However, the connection between the plurality of connection bars 310 is not limited thereto, and may be determined according to actual requirements.

Referring to fig. 2 and 3, in one embodiment, the guard assembly includes a bumper fascia 400 and guard side plates 410. The protective side plates 410 are provided with two groups, and the two groups of protective side plates 410 are respectively located at two sides of the buffer panel 400. Specifically, one end of the protection side plate 410 is fixedly connected to the buffer panel 400, and the other end of the protection side plate 410 is fixedly connected to the base 100. It should be noted that, the buffer panel 400 is fixedly connected to the outermost side of the first buffer module, i.e., the buffer panel 400 may be allowed to be fixedly connected to the connection plate 320. In particular, the guard side plate 410 may allow for the inclusion of a plurality of bumper side plates 411 with adjacent bumper side plates 411 being hinged to one another. Therefore, when the shock absorbing panel 400 is externally impacted, the plurality of shock absorbing side plates 411 can be quickly deformed, so that the practical use effect of the shock absorbing device 20 is improved. It should be noted that, a certain obtuse angle exists between the adjacent buffer side plates 411, and the obtuse angle may be 170 °, 175 °, etc., and the specific size of the obtuse angle is not limited. By setting the adjacent buffer side plates 411 to an obtuse angle, folding between the adjacent buffer side plates 411 is facilitated.

Referring to fig. 1 and 6, in one embodiment, a lift assembly 50 is positioned between the vehicle body 10 and the cushioning device 20. Thus, it is possible to allow the lifting assembly 50 to be fixedly connected to the vehicle body 10, and to connect the lifting assembly 50 with the damper 20 in a driving manner, so as to drive the damper 20 to adjust the height. Specifically, the lift assembly 50 may allow for the inclusion of a lift cylinder 520, a guide rod 510, an upper mount 110, and a lower mount 111. Wherein, the guide rod 510 is fixedly connected with the vehicle body 10, and the upper mounting seat 110, the lower mounting seat 111 and the guide rod 510 are respectively in sliding connection. Therefore, by providing the upper and lower mounting seats 110 and 111 to be slidably coupled to the guide bar 510, the stability of the buffer device 20 during the lifting process can be improved. It should be noted that the upper mounting base 110 and the lower mounting base 111 are fixedly connected to the base 100, so as to drive the buffer device 20 to adjust the position through the base 100. The cylinder body of the lifting cylinder 520 may be allowed to be fixedly connected with the vehicle body 10, and the cylinder rod of the lifting cylinder 520 may be allowed to be fixedly connected with the upper mount 110. It should be noted that the movement direction of the lever of the lifting cylinder 520 with respect to the cylinder body thereof is consistent with the axial direction of the guide rod 510, and thus the buffer device 20 is driven to move along the axial direction of the guide rod 510 by the lifting cylinder 520. And then the buffer device 20 can be lifted and regulated according to the actual working condition.

In summary, the invention discloses a buffer device and an anti-collision vehicle, which can solve the problems that the existing anti-collision vehicle has poor protection performance and is difficult to effectively absorb kinetic energy generated by collision. The first buffer module, the second buffer module and the third buffer module are sequentially connected, so that the buffer device 20 can absorb energy in multiple stages, and meanwhile, the buffer plate 105 can relieve kinetic energy transmitted from multiple angles, so that the buffer device 20 can effectively absorb kinetic energy generated by impact.
