Description

Technical Field

[0001] The present application relates to the technical field of anti-collision buffer vehicles, and in particular to a rollover structure and an anti-collision buffer vehicle. Background Art

[0002] The current technology of the anti-collision bag of the anti-collision car is that the anti-collision bag is laid flat backwards when working. After the work is completed, the oil cylinder is extended to push the anti-collision bag to flip over, so that the anti-collision bag stands up. In this way, the anti-collision box is always in a standing state while the anti-collision car is driving.

[0003] In this regard, the Chinese patent application number is CN202321033944.X, which discloses a flip structure of the anti-collision buffer car anti-collision bag. This solution mainly requires that when placing the anti-collision bag, the first oil cylinder is started to drive the flip plate to rotate counterclockwise, and then the anti-collision bag is driven to rotate counterclockwise, and then the second oil cylinder is started to continue to drive the anti-collision bag to rotate counterclockwise until the anti-collision bag is placed horizontally. When the anti-collision bag needs to be put away, the reverse operation can be performed until it is placed horizontally above the chassis. Since connection points are set at both ends of the anti-collision bag, when the vehicle is running, the anti-collision bag is more stable, shakes less, and is not easy to damage the connection, which is conducive to extending its service life.

[0004] However, in the process of implementing the technical solutions in the embodiments of the present application, the inventors of the present application found that the above technology has at least the following technical problems:

[0005] The crash bag will affect the rollover structure after being hit, resulting in higher costs for each impact. Utility Model Content

[0006] In order to make up for the above deficiencies, the present application provides a flipping structure and an anti-collision buffer vehicle, aiming to improve the problems mentioned in the above background technology.

[0007] In the first aspect, an embodiment of the present application provides a flip structure, including a vehicle body and an anti-collision bag, wherein a rotating part is provided at the rear end of the vehicle body, and the anti-collision bag is mounted on the rotating part by means of self-breaking screws, and the anti-collision bag is placed obliquely on the vehicle body to form a fastback shape to reduce wind resistance.

[0008] In a specific implementation manner, a limiting frame is provided on the vehicle body, and the anti-collision bag rests on the limiting frame.

[0009] In the above implementation process, the limiting frame is used to help support the anti-collision bag to tilt on the vehicle body.

[0010] In a specific implementation, a spring pin is provided on the limiting frame, and the spring pin is connected to the anti-collision bag pin.

[0011] In the above implementation process, a spring pin is inserted into the anti-collision bag to provide additional support at the outer end of the anti-collision bag, thereby preventing the anti-collision bag from shaking when stored, thereby improving the stability of the anti-collision bag.

[0012] In a specific embodiment, the rotating member includes a rotating shaft and a bracket, the rotating shaft is rotatably connected to the rear end of the vehicle body, and the bracket is fixedly connected to the rotating shaft.

[0013] In a specific embodiment, the rotating member further includes a motor, the motor is mounted on the vehicle body, and the output end of the motor is connected to the rotating shaft.

[0014] In the above implementation process, the rotating shaft and the bracket can provide the anti-collision bag with a large angle of deflection. The anti-collision bag can be driven to deflect by driving the rotating shaft to rotate using a reduction motor. Compared with the two hydraulic cylinder structures in the prior art, the structure is simpler.

[0015] In a specific embodiment, the rotating member also includes a worm wheel and a worm, the worm wheel is connected to the rotating shaft, the worm is rotatably connected to the vehicle body, the worm is meshed with the worm wheel, and the worm is fixedly connected to the output end of the motor.

[0016] In the above implementation process, the worm gear and the worm can provide a deceleration effect, and the worm gear and the worm can provide a self-locking effect to help stabilize the posture of the anti-collision bag.

[0017] In a specific implementation manner, the bracket and the anti-collision bag are fixed together by the self-breaking screws, and the inner end of the anti-collision bag is movably pressed against the rear end of the vehicle body.

[0018] In the above implementation process, the anti-collision bag collapses after being hit, and the self-breaking screws break due to shear force. The energy of the impact is completely transferred to the vehicle body by the anti-collision bag, and the steering parts are avoided from being damaged by force. Afterwards, only the anti-collision bag and the self-breaking screws need to be replaced, reducing the cost of each collision.

[0019] In a second aspect, the present application further provides an anti-collision buffer vehicle, comprising the above-mentioned flipping structure.

[0020] Compared with the prior art, the beneficial effects of the present application are: the rotating part drives the anti-collision bag to tilt on the vehicle body to form a fastback shape to reduce wind resistance. When unfolded, the rotating part drives the anti-collision bag to rest against the vehicle body to withstand impact. When a collision occurs, the self-breaking screws break, so that the anti-collision bag is separated from the rotating part, thereby protecting the rotating part and reducing the cost of each collision.

[0026] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0027] See also Figure 1-Figure 3 The present application provides a flip structure, including a vehicle body 10 and an anti-collision bag 20. A rotating member 30 is provided at the rear end of the vehicle body 10. The anti-collision bag 20 is mounted on the rotating member 30 by means of self-breaking screws 40. The anti-collision bag 20 is placed on the vehicle body 10 at an angle to form a fastback shape to reduce wind resistance. The rotating member 30 drives the anti-collision bag 20 to tilt on the vehicle body 10 to form a fastback shape to reduce wind resistance. When unfolded, the rotating member 30 drives the anti-collision bag 20 to press against the vehicle body 10 to withstand impact. When impacting, the self-breaking screws 40 break, so that the anti-collision bag 20 is separated from the rotating member 30, thereby protecting the rotating member 30 and reducing the cost of each impact.

[0028] See also Figure 1-Figure 3 A limiting frame 50 is provided on the vehicle body 10, and the anti-collision bag 20 leans on the limiting frame 50. The limiting frame 50 is used to help support the anti-collision bag 20 to tilt on the vehicle body 10.

[0029] See also Figure 1-Figure 3 The limit frame 50 is provided with a spring pin 60, which is pin-connected with the anti-collision bag 20. The spring pin 60 is inserted into the anti-collision bag 20 to provide additional support at the outer end of the anti-collision bag 20, thereby preventing the anti-collision bag 20 from shaking when stored, and improving the stability of the anti-collision bag 20.

[0030] See also Figure 1-Figure 3 The rotating member 30 includes a rotating shaft 31 and a bracket 32. The rotating shaft 31 is rotatably connected to the rear end of the vehicle body 10, and the bracket 32 ​​is fixedly connected to the rotating shaft 31. The rotating member 30 also includes a motor 33. The motor 33 is mounted on the vehicle body 10, and the output end of the motor 33 is axially connected to the rotating shaft 31. The rotating shaft 31 and the bracket 32 ​​can provide a large angle of deflection of the anti-collision bag 20. The anti-collision bag 20 can be driven to deflect by driving the rotating shaft 31 to rotate by the reduction motor 33. Compared with the two hydraulic cylinder structures in the prior art, the structure is simpler.

[0031] See also Figure 1-Figure 3 The rotating member 30 further includes a worm wheel 34 and a worm 35, the worm wheel 34 is axially connected to the rotating shaft 31, the worm 35 is rotatably connected to the vehicle body 10, the worm 35 is meshed with the worm wheel 34, and the worm 35 is fixedly connected to the output end of the motor 33. The worm wheel 34 and the worm 35 can provide a deceleration effect, and the worm wheel 34 and the worm 35 can provide a self-locking effect to help stabilize the posture of the anti-collision bag 20.

[0032] See also Figure 1-Figure 3 The bracket 32 ​​and the anti-collision bag 20 are fixed together by the self-breaking screw 40, and the inner end of the anti-collision bag 20 is movably pressed against the rear end of the vehicle body 10. The anti-collision bag 20 collapses after being hit, and the self-breaking screw 40 breaks due to the shear force. The energy of the impact is completely transferred from the anti-collision bag 20 to the vehicle body 10, and the steering parts are avoided from being damaged by the force. After that, only the anti-collision bag 20 and the self-breaking screw 40 need to be replaced, which reduces the cost of each collision.

[0033] See also Figure 1-Figure 3 The present application further provides an anti-collision buffer vehicle, including the above-mentioned flipping structure.

[0034] The working principle of the flip structure is as follows: when driving, the anti-collision bag 20 is tilted against the limit frame 50 to form a fastback shape to reduce wind resistance, and the spring pin 60 is inserted into the anti-collision bag 20 to provide additional support at the outer end of the anti-collision bag 20 to prevent the anti-collision bag 20 from shaking when stored, thereby improving the stability of the anti-collision bag 20. When unfolding, the spring pin 60 is opened, and the motor 33 drives the shaft 31 to rotate through the deceleration of the worm gear 34 and the worm 35, thereby driving the anti-collision bag 20 to unfold backward until the inner end of the anti-collision bag 20 reaches the rear end of the vehicle body 10. When colliding, the anti-collision bag 20 collapses after being hit, and the screws are broken by themselves. The wire 40 breaks due to the shear force, and the energy of the impact is completely transferred from the anti-collision bag 20 to the vehicle body 10, thereby avoiding the situation where the steering part is damaged by the force. After that, only the anti-collision bag 20 and the self-breaking screw 40 need to be replaced, thereby reducing the cost of each collision. In summary, the rotating part 30 drives the anti-collision bag 20 to tilt on the vehicle body 10 to form a fastback shape to reduce wind resistance. When unfolded, the rotating part 30 drives the anti-collision bag 20 to press against the vehicle body 10 to withstand the impact. During the collision, the self-breaking screw 40 breaks, so that the anti-collision bag 20 is separated from the rotating part 30, thereby protecting the rotating part 30 and reducing the cost of each collision.
