[0034] This application makes improvements and innovations and proposes the following embodiments.

[0035] In some embodiments, see Figures 1 to 10 , provides a buffer mechanism for an electric anti-collision buffer vehicle, comprising: A vehicle body 1 is provided with a battery assembly 2 therein. The battery assembly 2 includes a battery body 21, a housing 22, and a buffer structure 23. The battery body 21 is fixedly disposed within the housing 22, and the buffer structure 23 is fixedly disposed on the housing 22. The buffer structure 23 is fixedly connected to the vehicle body 1. A fixing frame 3, the fixing frame 3 is fixedly connected to the rear end of the vehicle body 1; Buffer 4, buffer 4 is located at the rear of the vehicle body 1; The driving structure 5 is mounted on the fixing frame 3 ; the driving structure 5 is electrically connected to the battery body 21 ; the driving structure 5 has a pushing member for driving the buffer member 4 to expand and retract.

[0036] The battery body 21 is protected in the shell 22 by providing a shell 22, and the shell 22 is protected by providing a buffer structure 23 on the shell 22. When the vehicle body 1 is subjected to impact force, the buffer structure 23 absorbs the impact force of the vehicle body 1 on the shell 22, thereby preventing the battery body 21 from being squeezed and deformed under the impact force, thereby ensuring the safe use of the battery body 21.

[0037] The battery assembly 2 is used to provide power for the vehicle body 1 to travel and for electrical equipment in the vehicle body 1 . At the same time, the battery assembly 2 can provide electrical energy for the driving structure 5 to drive the buffer member 4 to expand and retract.

[0038] The buffer 4 is located at the rear of the vehicle. The battery body 21 is electrically connected to the drive structure 5, providing power to the drive structure 5 to drive the movement of the pusher, which in turn drives the expansion and contraction of the buffer 4. By configuring the drive structure 5, the position of the buffer 4 can be changed to realize the use and contraction of the buffer 4. When the buffer 4 is contracted, it facilitates the movement of the anti-collision buffer vehicle. When the buffer 4 is deployed, its cushioning capacity is maximized.

[0039] The vehicle body 1 includes a front and a vehicle compartment, with a battery assembly 2 fixedly mounted within the compartment. The battery assembly 2 is used to drive the movement of the vehicle body 1 and the movement of the telescopic parts. The buffer structure 23 includes multiple dampers 231 and baffles 232. The multiple dampers 231 are arranged at intervals around the circumference of the outer shell 22, and there are four baffles 232, which surround the circumference of the outer shell 22. One end of the multiple dampers 231 is fixedly connected to the outer shell 22, and the other end is fixedly connected to the baffle 232. When the vehicle body 1 is subjected to an impact, the impact force is transmitted to the baffle 232, which then transmits the impact force to the damper 231. The damper 231's ability to absorb the impact force is converted into liquid heat energy, reducing the impact force's effect on the outer shell 22 and ensuring the safe use of the battery body 21. This improves the protection level of the protective structure of the battery assembly 2 and enhances impact resistance.

[0040] A pressure sensor is installed within the housing 22, located between the inner wall of the housing 22 and the battery body 21. When the housing 22 is deformed by an impact, the pressure sensor transmits a signal to a chip inside the vehicle body. When the input pressure signal exceeds a threshold, indicating that the deformation of the housing 22 has affected the safe use of the battery body 21, the chip outputs a corresponding signal to cut off the power output of the battery body 21, thus protecting the safe use of the battery body.

[0041] A cooling duct is installed within the outer shell 22, passing through the outer shell 22 and wrapping around the battery body 21. A portion of the cooling duct is located at the cold air outlet of the vehicle air conditioner. This allows heat generated by the battery body 21 to be promptly removed and exchanged at the cold air outlet of the vehicle air conditioner. This ensures the safe use of the battery body 21 and improves the safety level of the battery assembly 2.

[0042] Specifically, the damper 231 is a shock absorber used in automobile suspension. The damper 231 is widely distributed, easy to obtain, and reduces production costs.

[0043] In one embodiment, the buffer member 4 includes a shell and an energy-absorbing filler 222 filled in the shell; the shell is hinged to the pusher. The energy-absorbing filler 222 can improve the energy-absorbing effect of the buffer member 4.

[0044] Specifically, the energy absorbing filler 222 is an aluminum honeycomb structure. The profile of the aluminum honeycomb structure has a good energy absorbing effect.

[0045] In one embodiment, a reinforcing rib 221 is fixedly provided on the bottom of the outer shell 22, the battery body 21 is fixedly connected to the reinforcing rib 221, the battery body 21 is spaced apart from the inner wall of the outer shell 22, and the gap between the inner wall of the outer shell 22 and the battery body 21 is filled with an energy-absorbing filler 222. The provision of the reinforcing rib 221 can increase the strength of the outer shell 22, reduce deformation of the outer shell 22, and ensure the safety of the battery body 21.

[0046] Specifically, the reinforcing ribs 221 are rods arranged horizontally and vertically, and the rods are fixedly connected to each other.

[0047] In one embodiment, the driving structure 5 includes: a connecting base 51, a first telescopic cylinder 52, and a second telescopic cylinder 53; the connecting base 51 is hinged to the vehicle body 1; the buffer 4 is detachably connected to the connecting base 51; the first telescopic cylinder 52 is fixedly connected to the fixing frame 3, the second telescopic cylinder 53 is hinged to the telescopic end of the first telescopic cylinder 52, and the telescopic end of the second telescopic cylinder 53 is hinged to the connecting base 51. The first telescopic cylinder 52 drives the second telescopic cylinder 53 to move, and the second telescopic cylinder 53 drives the connecting base 51 to rotate. The rotation of the connecting base 51 in turn drives the buffer 4 to rotate together. After the buffer 4 rotates to a certain angle, it can be expanded and retracted. That is, the buffer 4 is expanded when it rotates parallel to the ground, and retracted when it rotates perpendicular to the ground.

[0048] Providing two telescopic cylinders to jointly promote the rotation of the connecting seat 51 can reduce the telescopic stroke of a single telescopic cylinder and reduce the size of the telescopic cylinder.

[0049] Specifically, the first telescopic cylinder 52 is telescopically telescopic in a horizontal direction. A movable groove is provided on the fixing frame 3. The telescopic end of the first telescopic cylinder 52 is movably clamped in the movable groove, and the movable groove extends in a horizontal direction.

[0050] The first telescopic cylinder 52 and the second telescopic cylinder 53 are both hydraulic cylinders.

[0051] In one embodiment, the connecting base 51 is provided with a connecting member comprising a rotating shaft 54, a connecting plate 55, and a drive shaft 56. A connecting slot 57 is defined on the connecting base 51. The rotating shaft 54 is rotatably connected to the connecting slot 57, and the connecting plate 55 is fixedly connected to the rotating shaft 54. The buffer 4 is provided with a first retaining slot 41 for the retaining plate 55 to engage. The drive shaft 56 engages with the rotating shaft 54 for transmission. The drive shaft 56 drives the rotating shaft 54 to rotate, thereby rotating the connecting plate 55. The connecting plate 55 rotates and engages the first retaining slot 41, ultimately achieving a detachable connection between the connecting base and the buffer 4. This simple and rationally designed structure facilitates assembly and disassembly of the connecting base 51 and the buffer 4.

[0052] Specifically, the connecting seat 51 is provided with a second slot 58 for the buffer member 4 to be snapped in. By snapping the buffer member 4 into the second slot 58, the firmness of the connection between the connecting seat 51 and the buffer member 4 is improved.

[0053] The drive shaft 56 and the rotating shaft 54 are driven by a worm gear. By adopting the worm gear transmission, the rotating shaft 54 can be driven to rotate only by rotating the drive shaft 56, thereby preventing the rotating shaft 54 from rotating arbitrarily and causing the connecting plate 55 to leave the slot, thereby ensuring the safety of the connection.

[0054] In one embodiment, the inner wall of the connecting groove 57 is further provided with a first sliding groove 571 for the movement of the rotating shaft 54 and a second sliding groove 572 for the movement of the driving shaft 56; a first slider 573 is slidably provided in the first sliding groove 571, and the rotating shaft 54 is rotatably connected to the first slider 573; a second slider 574 is slidably provided in the second sliding groove 572, and the driving shaft 56 is rotatably connected to the second slider 574; two springs 57 are respectively provided in the first sliding groove 571 and the second sliding groove 572, which are in one-to-one correspondence with the first slider 573 and the second slider 574. 5. The first slider 573 is fixedly connected to the first push rod 576, and the connecting member is further provided with a second push rod 577 that can slide relative to the connecting groove 57; the second push rod 577 has a lifting inclined surface, and the first push rod 576 has an inclined surface that abuts against the lifting inclined surface; the connecting seat 51 is fixedly connected to the rotating member 59, which is threadedly engaged with the second push rod 577 and can rotate relative to the second push rod 577; the connecting plate 55 has a hook portion 551, and the inner wall of the first clamping groove 41 is provided with a hook groove 42 for the hook portion 551 to be clamped into.

[0055] By rotating the rotating member 59 on the connecting seat 51, the rotating member 59 drives the second push rod 577 to telescope and move, and then the second push rod 577 pushes up the first push rod 576, and the first push rod 576 drives the first slider 573 to move in the first slide groove 571, and the first slider 573 drives the rotating shaft 54 to move. The movement of the rotating shaft 54 squeezes the driving shaft 56 to move, and the movement of the driving shaft 56 drives the second slider 574 to move in the second slide groove 572. The two springs 575 corresponding to the first slider 573 and the second slider 574 are respectively used to push the rotating shaft 54 and the driving shaft 56 to return to their original positions, and ensure that the rotating shaft 54 and the driving shaft 56 are always engaged.

[0056] Specifically, the rotating member 59 includes a fixed portion 591 and a rotating portion 592. The fixed portion 591 is fixedly connected to the connecting seat 51. The rotating portion 592 has a threaded hole. The second push rod 577 passes through the threaded hole and is threadedly engaged with the rotating portion 592. The second push rod 577 also passes through the fixed portion 591 and is movable relative to the fixed portion 591. The second push rod 577 has a limiting slot. The fixed portion 591 is fixedly provided with a limiting block that cooperates with the limiting slot. The rotating portion 592 is rotatably connected to the fixed portion 591. The fixed portion 591 and the rotating portion 592 are both provided with mutually cooperating hooks 594. The connection between the hooks 594 of the fixed portion 591 and the rotating portion 592 is rotatably connected via a ball 593.

[0057] The hook 594 realizes a snap connection between the fixed portion 591 and the rotating portion 592, and the hook 594 is rotatably connected via the ball bearing 593, enabling the fixed portion 591 and the rotating portion 592 to rotate relative to each other. The relative rotation between the rotating portion 592 and the second push rod 577 realizes the telescopic movement of the second push rod 577. The second push rod 577 lifts the first push rod 576, which drives the first slider 573 to move in the first slide groove 571. The first slider 573 drives the rotating shaft 54 to move. The movement of the rotating shaft 54 squeezes the drive shaft 56 to move. The movement of the drive shaft 56 drives the second slider 574 to move in the second slide groove 572, thereby achieving the mutual engagement and separation of the hook portion 551 and the hook groove 42.

[0058] In one embodiment, there are multiple buffer members 4, and the multiple buffer members 4 are sequentially connected together through the connecting tube 6. The multiple buffer members 4 are sequentially connected together through the connecting tube 6 to facilitate the installation and removal of the buffer members 4.

[0059] Specifically, two adjacent buffer members 4 are respectively inserted into both ends of the connecting tube 6 for connection.

[0060] In one embodiment, a curved buffer rod 7 is connected to the connecting base 51. The connecting base 51 has a slot in which one end of the buffer rod 7 is inserted and secured. The buffer rod 7 is longer than the buffer element 4. The other end of the buffer element 4 is fixedly connected to a buffer bag 71, which is spaced apart from the buffer element 4. The provision of the buffer rod 7 and the buffer bag 71 can enhance the buffering capacity of the anti-collision buffer mechanism and reduce the impact force of the buffer element 4.

[0061] Specifically, the buffer bag is provided with the same energy-absorbing filler as that in the buffer element. One end surface of the buffer bag is an arc surface, and the other end surface is fixedly connected to the buffer rod.

[0062] Specifically, the buffer rod 7 is further fixedly connected to a support wheel 72; the support wheel 72 abuts against the ground. The support wheel 72 can provide support force for the buffer rod 7 and reduce the torsional stress of the buffer rod 7 on the connecting seat 51.

[0063] In one embodiment, the number of buffer rods 7 is multiple, and the multiple buffer rods 7 are arranged at intervals along the circumference of the buffer element 4; two adjacent buffer rods 7 are connected together by a sleeve 8. The multiple buffer rods 7 can improve the buffering capacity of the anti-collision buffer car buffer mechanism and reduce the impact force of the buffer element 4.

[0064] In one embodiment, Figure 10 As shown, the driving structure 5 includes: a driving motor 91 fixedly connected to the fixing frame 3, a screw rod 92, a slider 93, a first rod body 94, a second rod body 95, a third rod body 96, a first connecting rod 97, a second connecting rod 98, and a third connecting rod 99; the number of the buffer members 4 is three, and they are slidably connected to the first rod body 94, the second rod body 95, and the third rod body 96 in a one-to-one correspondence; the screw rod 92 is rotatably connected to the fixing frame 3; the power output end of the driving motor 91 is transmission-connected to the screw rod 92 The slider 93 is threadedly engaged with the screw rod 92; the first rod body 94 is hinged to the fixed frame 3, one end of the first connecting rod 97 is hinged to the slider 93, and the other end is hinged to the first rod body 94; the second rod body 95 is hinged to the first rod body 94, one end of the second connecting rod 98 is hinged to the first connecting rod 97, and the other end is hinged to the second rod body 95; the third rod body 96 is hinged to the second rod body 95, and one end of the third connecting rod 99 is hinged to the first rod body 94, and the other end is hinged to the third rod body 96.

[0065] The driving motor 91 drives the screw rod 92 to rotate, thereby causing the slider 93 on the screw rod 92 to move up and down. When the slider 93 moves down, the first connecting rod 97 on the slider 93 pushes the first rod body 94 to extend, the second connecting rod 98 pulls the second rod body 95 to rotate, and the third connecting rod 99 pushes the third rod body 96 to rotate, ultimately causing the first rod body 94, the second rod body 95, and the third rod body 96 to extend substantially in the same straight line, ultimately causing the three buffer members 4 to be spaced apart on substantially the same straight line, thereby achieving the deployment of the buffer members 4. When the slider 93 moves up, the first connecting rod 97 on the slider 93 pulls the first rod body 94 to rotate in the vertical direction, the second connecting rod pushes and pulls the second rod body 95 to rotate in the vertical direction, and the third connecting rod 99 pushes the third rod body 96 to rotate in the vertical direction, ultimately causing the first rod body 94, the second rod body 95, and the third rod body 96 to extend substantially in the vertical direction, and the three buffer members 4 to be close together in the vertical direction.

[0066] Specifically, the buffer member 4 is provided with a sliding groove 43, and a latch 10 is fixedly mounted on each of the first rod 94, the second rod 95, and the third rod 96. The latch 10 slides within the sliding groove 43. When the first rod 94, the second rod 95, and the third rod 96 are brought together in a vertical direction, the three buffer members 4 are brought together and squeezed against each other, thereby causing the corresponding buffer member 4 to move within the sliding groove 43, thereby achieving a closer and more compact arrangement of the three buffer members 4.

[0067] Specifically, the drive motor 91 and the screw rod 92 are driven by a worm gear. The worm gear transmission is adopted, so that the screw rod 92 can be driven to rotate only when the drive motor 91 rotates, thereby preventing the screw rod 92 from rotating arbitrarily and ensuring that the extension and retraction of the three buffer members 4 can be carried out stably.
