DETAILED DESCRIPTION
[0022] The present invention will be further described below in conjunction with specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention but are not intended to limit the present invention.
[0023] Example: Figure 1 , Figure 2 , Figure 3 , Figure 4 A shock absorbing seat for an electric vehicle is shown.
[0024] The first embodiment of the utility model refers to Figure 1 and Figure 2 A shock-absorbing seat for an electric vehicle comprises a mounting plate 1 and a base plate 7. The mounting plate 1 is a trapezoidal plate structure with a small left end and a large right end. A leather pad 101 is laid on the upper part of the mounting plate 1. Armrests 3 are arranged at both ends of the front and rear ends of the middle part of the upper surface of the mounting plate 1. The middle rod of the armrest 3 is sleeved with an anti-slip sleeve 301 on the outside. A backrest 2 is arranged on the upper right side of the mounting plate 1. The lower part of the mounting plate 1 is connected to the air spring 8 arranged on the upper part of the base plate 7 through an adjustment component. Evenly distributed mounting holes 19 are provided on the outer side of the upper surface of the base plate 7. The seat can be fixed to the electric vehicle through the mounting holes 19. During the driving of the electric vehicle, the air spring 8 can reduce vibration by adjusting its own telescopic adjustment. At the same time, the adjustment component cooperates with the air spring 8, so that the seat can automatically swing forward and backward when the electric vehicle shakes, thereby further improving the shock-absorbing effect of the seat and improving the comfort of the people. As a preferred embodiment, Figure 3 and Figure 4As shown, the adjustment component includes a first support seat 4 and a second support seat 5. The first support seat 4 is fixedly arranged on the lower left side of the mounting plate 1, and the second support seat 5 is slidably arranged inside the dovetail groove 102 opened on the lower right side of the mounting plate 1. The lower ends of the first support seat 4 and the second support seat 5 are both provided with connecting blocks 6 through a rotating shaft. The front and rear ends of the lower surface of the connecting block 6 are respectively fixedly connected to the top of the corresponding air spring 8. It also includes a shock-absorbing spring 20. The shock-absorbing spring 20 is evenly arranged on the outside of the upper surface of the bottom plate 7. When the electric vehicle is running and shaking occurs, the seat will vibrate accordingly, and the vibration force of the seat will be transmitted to the shock-absorbing spring 20. The shock-absorbing spring 20 itself swings rapidly, and the vibration of the seat is further quickly reduced.
[0025] The second embodiment of the utility model refers to Figure 3 and Figure 4 As shown, a buffer device for protecting personnel during braking is provided on the bottom plate 7, and the buffer device includes a guide tube 10, which is mounted on the upper part of the bottom plate 7 through a fixed seat 9, and a guide column 11 is slidably provided at the left sealing plate of the guide tube 10, and a small wheel 12 is rotatably provided at the left end of the guide column 11 through a rotating shaft, and a top support block 13 is provided at the lower part of the mounting plate 1, and a large wheel 14 is rotatably provided at the lower end of the top support block 13 through a rotating shaft, and the large wheel 14 and the small wheel 12 are arranged in cooperation with each other up and down, and a control ball 15 is movably provided inside the guide tube 10, and preferably, the guide tube 10 is arranged in an inclined manner, and the left end of the guide tube 10 is higher than the right end, and a ball head 16 is provided at the right end of the guide column 11. Preferably, a buffer spring 17 is provided at the left end of the guide tube 10, and the buffer spring 17 is arranged in cooperation with the control ball 15.
[0026] When the electric vehicle is in motion, if the brakes are suddenly applied, due to inertia, the control ball 15 will move leftward along the guide tube 10, and then hit the ball head 16, so that the guide column 11 slides along the sliding hole at the left sealing plate of the guide tube 10, thereby pushing the small wheel 12 to move outward, and the small wheel 12 pushes the large wheel 14 upward during the movement, and the large wheel 14 pushes the left end of the mounting plate 1 upward through the supporting block 13, so that the mounting plate 1 rotates backward through the rotating shaft at the lower end of the first supporting seat 4, and the two air springs 8 on the right are compressed. At the same time, the second supporting seat 5 moves along the swallow The tail slide groove 102 is slidably adjusted to move one side of the seat back 2 downward, thereby allowing the passenger to tilt toward one side of the seat back 2, thereby avoiding the passenger being thrown out of the seat due to excessive inertia and improving the safety of the seat. When the electric vehicle is driving normally, since the guide tube 10 is tilted, the left end of the guide tube 10 is higher than the right end. Therefore, the control ball 15 can automatically slide to the right end of the guide tube 10, and the buffer spring 17 can prevent the control ball 15 from sliding toward the right end of the guide tube 10 and vibrating due to hitting the right side cover of the guide tube 10.
[0027] The third embodiment of the present utility model is as follows Figure 1 As shown, it also includes a bellows 18, which is arranged between the mounting plate 1 and the base plate 7. The buffer device, the adjustment assembly and the shock-absorbing spring 20 are all located inside the bellows 18. The bellows 18 can be extended and compressed when the seat swings, thereby protecting the internal components of the seat while ensuring the normal operation of the internal components of the seat.
[0028] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. The various components mentioned in the utility model are common technologies in the existing field. The technicians in this industry should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only to illustrate the principles of the utility model. Without departing from the spirit and scope of the utility model, the utility model will have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
