[0029] Embodiment 1
[0030] As Figures 1-4The application discloses an unmanned vehicle provided with a buffer anti-collision mechanism, which comprises a vehicle body 1, an anti-collision column 2 arranged on the vehicle body 1, an anti-collision rod 3 arranged on the anti-collision column 2, an anti-collision plate 4 arranged on the anti-collision rod 3, a sliding mechanism arranged on the anti-collision plate 4, a force releasing mechanism arranged on the sliding mechanism, a reminding mechanism arranged on the vehicle body 1 and connected with the force releasing mechanism, and a brake mechanism arranged on the vehicle body 1 and connected with the force releasing mechanism.
[0031] The anti-collision column 2 is provided with an anti-collision groove, and the anti-collision rod 3 is arranged in the anti-collision groove; a third spring with one end abutting against the bottom of the anti-collision groove and the other end fixed on the end of the anti-collision rod 3 is further arranged in the anti-collision groove.
[0032] When the anti-collision plate is inwardly extruded due to external impact, the anti-collision rod moves into the anti-collision groove, and the movement of the anti-collision rod extrudes the third spring, thereby converting the impact force into the elastic force of the spring, and effectively reducing the impact force directly borne by the vehicle body.
[0033] Dampers are arranged on the first spring, the second spring and the third spring, so that the conversion capacity of the first spring, the second spring and the third spring to force is improved, and the buffer effect of the product is further improved.
[0034] The number of the sliding mechanisms is two, and the sliding mechanisms are arranged on the upper half and the lower half of the front side of the anti-collision plate 4 respectively; the sliding mechanism comprises a sliding groove 5 arranged on the upper half or the lower half of the front side of the anti-collision plate 4, at least one sliding column 6 vertically arranged in the sliding groove 5, a sliding block 7 arranged in the sliding groove 5 and penetrated by the sliding column 6, and a first spring 8 sleeved on the sliding column 6, with the upper end fixed on the upper side wall of the sliding groove 5 and the lower end fixed on the sliding block 7.
[0035] The sliding mechanism is provided with the sliding block, so that the force releasing mechanism arranged on the sliding block can move up and down along the sliding column, and the first spring is compressed or stretched when the sliding block slides, thereby converting part of the impact force into the elastic force of the first spring in the process of compression or stretching of the first spring, and effectively improving the buffer effect of the product.
[0036] The number of the force releasing mechanisms is two, and the force releasing mechanisms are symmetrically arranged on the sliding blocks 7 of the two sliding mechanisms.
[0037] The force releasing mechanism comprises a triangular plate 9 with a slope on the front side, at least one rotating groove 10 horizontally arranged on the slope of the triangular plate 9, a rotating column 11 horizontally arranged in the rotating groove 10, and two second springs 12 arranged on the left and right ends of the rotating column 11; one end of the second spring 12 is fixed on the end of the rotating column 11, and the other end is fixed on the left side wall or the right side wall of the rotating groove 10.
[0038] The front side of the rotating column 11 protrudes from the slope of the triangular plate 9.
[0039] Because the two force relief mechanisms are symmetrically arranged up and down, the triangular plates of the two force relief mechanisms can move up and down respectively when impacted by external force, which can effectively convert the direction of the external force and effectively trigger the reminding mechanism and the brake mechanism.
[0040] The slope surface of the triangular plate can decompose the impact force into horizontal component and upward or downward component when impacted by the impact force, thereby achieving the effect of differentiating the impact force. When the triangular plate moves up or down, the rotating column rotates in the friction process with the impact object, and the rotation of the rotating column drives the second spring to rotate, thereby effectively converting part of the impact force into the elastic force of the second spring, further improving the buffering effect of the product.
[0041] The reminding mechanism is composed of a gas tank 14 arranged on the vehicle body 1 above the anti-collision plate 4, two air holes 15 arranged on the gas tank 14 and connecting the inner cavity of the gas tank 14 with the outside, one-way valves 16 respectively arranged in the two air holes 15, a whistle 17 arranged outside any one of the air holes 15, a piston plate 18 horizontally arranged in the inner cavity of the gas tank 14, and a first telescopic column 13 arranged at the upper end of the lower side of the piston plate 18 and penetrating the lower side of the gas tank 14; the lower end of the first telescopic column 13 is fixed on the triangular plate 9 of the force relief mechanism above.
[0042] The air hole 15 is arranged in the upper half of the gas tank 14; the one-way valve 16 in the air hole 15 outside which the whistle 17 is arranged is an air outlet one-way valve, and the one-way valve 16 in the other air hole 15 is an air inlet one-way valve.
[0043] When the triangular plate moves up, the first telescopic column will drive the piston plate to move up, and in the process of moving up, the piston plate will extrude the air in the gas tank outward through the air outlet one-way valve, and the air will make the whistle emit a reminding sound when flowing through the whistle.
[0044] The brake mechanism is composed of a second telescopic column 20 arranged on the lower side of the triangular plate 9 of the force relief mechanism below, and a lifting block 21 arranged below the second telescopic column 20.
[0045] When the triangular plate moves down, the second telescopic column will drive the lifting block to move down, and the lifting block can play the role of brake after contacting the ground, to further assist the vehicle to stop, so as to reduce the damage caused by impact. In actual use, rubber blocks or tooth blocks can be arranged at the bottom of the lifting block to further improve the stopping effect of the lifting block.
[0046] The first telescopic column and the second telescopic column are both prior art, and each of the first telescopic column and the second telescopic column is composed of a fixed column and a moving column, the fixed column is used for fixing the first telescopic column and the second telescopic column on the vehicle body, and the moving column can slide in a fixed groove arranged on the fixed column, thereby achieving the telescopic effect, and a person skilled in the art can complete the setting and use of the first telescopic column and the second telescopic column according to the above description without creative labor, and thus no further description is given herein.
[0047] It should be noted that all features disclosed in the specification, or all steps of the methods or processes disclosed, can be combined in any combination, except where such combinations are mutually exclusive.
[0048] In addition, the above specific embodiments are exemplary, and those skilled in the art can come up with various solutions under the inspiration of the disclosure of the present application, and these solutions also belong to the disclosed range of the present application and fall within the protection scope of the present application. Those skilled in the art should understand that the specification and drawings of the present application are illustrative and do not constitute a limitation on the claims. The protection scope of the present application is defined by the claims and their equivalents.
