Description

Technical Field

[0001] This utility model belongs to the field of vehicle seat technology, and in particular relates to a seat assembly suspension. Background Technology

[0002] Vibrations caused by uneven road surfaces are transmitted through the vehicle body to the seats, causing physiological and psychological effects on drivers and passengers. Prolonged exposure to strong vibrations can cause physical and psychological harm. Seat suspension is designed to reduce the harm caused by vibrations to drivers and passengers.

[0003] The utility model patent with authorization announcement number CN212555928U discloses a travel adjustable seat suspension and driver's seat, including a frame, the frame including an upper suspension, a telescopic suspension and a lower suspension, the telescopic suspension being disposed between the upper suspension and the lower suspension and connected to the upper suspension and the lower suspension; the telescopic suspension is provided with an elastic compression component and an air pressure adjustable air pressure damper respectively connected to the upper suspension and the lower suspension.

[0004] The aforementioned application document uses the upper and lower suspensions for support and fixation. When the upper suspension is subjected to a certain pressure (vertically downward), the adjustable seat suspension will rebound vertically, the elastic compression component will be compressed, and the angle of the air damper will change with the pressure, thereby realizing the up-and-down reciprocating motion. After long-term use, the air damper may experience pressure leakage, which can easily lead to a deterioration in overall performance, and therefore needs to be improved. Utility Model Content

[0005] The purpose of this invention is to provide a seat assembly suspension that solves the existing problems.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a seat assembly suspension, comprising a base plate, a cross arm and a buffer mechanism on the top of the base plate, a top plate on the end of the cross arm away from the base plate, mounting holes on the top of both the base plate and the top plate, a mounting groove on the top of the top plate, and a lubrication mechanism on the bottom of the top plate; the buffer mechanism comprises a slide cylinder, a support block, a rotating shaft and a fixing plate, the bottoms of the slide cylinder and the fixing plate being fixedly connected to the top of the base plate, a slide rod being slidably connected inside the slide cylinder, a buffer spring being sleeved on the surface of the slide rod, the top of the support block being fixedly connected to the bottom of the top plate, a connecting frame and a limiting rod being fixedly connected to the side of the support block, torsion springs being provided at both ends of the rotating shaft, the rotating shaft being rotatably connected to the torsion springs at both ends, a contact block being fixedly connected to the surface of the rotating shaft, and a deceleration block being fixedly connected to the side of the fixing plate.

[0008] Furthermore, in the initial state, the two ends of the buffer spring are in contact with the top of the slide and the bottom of the top plate, respectively. When the top plate is impacted and moves downward, the buffer spring will absorb the impact force and be gradually compressed.

[0009] Furthermore, the end of the limiting rod away from the support block is close to the bottom of the contact block, and the presence of the limiting rod prevents the contact block from rotating downwards.

[0010] Furthermore, the end of the contact block away from the connecting frame is arc-shaped, and the lateral length of the contact block is greater than the lateral distance from the rotating shaft to the fixed plate. When the contact block moves downward, it will contact the deceleration block on the side of the fixed plate.

[0011] Furthermore, the deceleration block is generally semi-cylindrical, and the material of the deceleration block is rubber. When the contact block is squeezed against the semi-cylindrical rubber deceleration block, a large resistance will be generated.

[0012] Furthermore, the lubrication mechanism includes a lubricating oil tank and a pressure chamber. The tops of both the lubricating oil tank and the pressure chamber are fixedly connected to the bottom of the top plate. The piston inside the pressure chamber is slidably connected to a piston rod, and a counterweight is fixedly connected to the bottom of the piston rod. A suction pipe is passed through and fixedly connected to the rear end of the pressure chamber. The end of the suction pipe away from the pressure chamber is passed through and fixedly connected to the lubricating oil tank. A spray pipe is passed through and fixedly connected to the side of the pressure chamber.

[0013] Furthermore, both the suction pipe and the spray pipe are equipped with one-way valves. The end of the spray pipe away from the pressure chamber is close to the slide rod. When a negative pressure is formed in the pressure chamber, it will draw lubricating oil from the lubricating oil tank through the suction pipe. When the pressure chamber is squeezed, the lubricating oil will be sprayed out through the spray pipe.

[0014] This utility model has the following beneficial effects:

[0015] This utility model incorporates a buffer mechanism, which, when the overall seat suspension is used, absorbs the impact force through the buffer spring when the top plate is impacted, thus providing a buffering effect. When the impact is large, the buffer spring rebounds and restores its original state, and the force of the rebound is reduced by the cooperation of components such as contact blocks and deceleration blocks, preventing back-and-forth bouncing and improving the buffering effect.

[0016] This utility model incorporates a lubrication mechanism, which, when the top plate is subjected to a large impact, utilizes the pressure chamber, piston rod, counterweight, and other components to spray lubricating oil from the nozzle onto the slide rod and buffer spring, thus lubricating these components and slowing down structural aging.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-5This utility model relates to a seat assembly suspension, comprising a base plate 1, a cross arm 2 and a buffer mechanism 6 on the top of the base plate 1, a top plate 3 at the end of the cross arm 2 away from the base plate 1, mounting holes 4 on the top of both the base plate 1 and the top plate 3, a mounting groove 5 on the top of the top plate 3, and a lubrication mechanism 7 at the bottom of the top plate 3; the buffer mechanism 6 comprises a slide cylinder 61, a support block 64, a rotating shaft 66 and a fixing plate 610, the bottoms of the slide cylinder 61 and the fixing plate 610 being flush with the top of the base plate 1. The slide cylinder 61 is fixedly connected to the slide rod 62, and the surface of the slide rod 62 is fitted with a buffer spring 63. The top of the support block 64 is fixedly connected to the bottom of the top plate 3. The side of the support block 64 is fixedly connected to the connecting frame 65 and the limiting rod 69. Both ends of the rotating shaft 66 are provided with torsion springs 67. The rotating shaft 66 is rotatably connected to the torsion springs 67 at both ends. The surface of the rotating shaft 66 is fixedly connected to the contact block 68. The side of the fixed plate 610 is fixedly connected to the deceleration block 611.

[0028] As shown in the figure, the two ends of the buffer spring 63 initially abut against the top of the slide cylinder 61 and the bottom of the top plate 3, respectively. When the top plate 3 is impacted and moves downward, the buffer spring 63 absorbs the impact force and is gradually compressed.

[0029] As shown in the figure, the end of the limiting rod 69 away from the support block 64 is close to the bottom of the contact block 68. The presence of the limiting rod 69 prevents the contact block 68 from rotating downwards.

[0030] As shown in the figure, the end of the contact block 68 away from the connecting frame 65 is arc-shaped, and the lateral length of the contact block 68 is greater than the lateral distance from the rotating shaft 66 to the fixed plate 610. When the contact block 68 moves downward, it will contact the deceleration block 611 on the side of the fixed plate 610.

[0031] As shown in the figure, the deceleration block 611 is semi-cylindrical in shape and made of rubber. When the contact block 68 is squeezed against the semi-cylindrical rubber deceleration block 611, a large resistance will be generated.

[0032] As shown in the figure, the lubrication mechanism 7 includes a lubricating oil tank 71 and a pressure chamber 72. The tops of both the lubricating oil tank 71 and the pressure chamber 72 are fixedly connected to the bottom of the top plate 3. The piston inside the pressure chamber 72 is slidably connected to a piston rod 73. A counterweight block 74 is fixedly connected to the bottom of the piston rod 73. A suction pipe 75 is passed through and fixedly connected to the rear end of the pressure chamber 72. The end of the suction pipe 75 away from the pressure chamber 72 is passed through and fixedly connected to the lubricating oil tank 71. A spray pipe 76 is passed through and fixedly connected to the side of the pressure chamber 72.

[0033] As shown in the figure, both the suction pipe 75 and the spray pipe 76 are equipped with one-way valves. The end of the spray pipe 76 away from the pressure chamber 72 is close to the slide rod 62. When a negative pressure is formed in the pressure chamber 72, it will draw lubricating oil from the lubricating oil tank 71 through the suction pipe 75. When the pressure chamber 72 is squeezed, the lubricating oil will be sprayed out through the spray pipe 76.

[0034] A specific application of this embodiment is as follows: the entire device is installed inside the vehicle through the mounting holes 4 on the base plate 1, and the seat is installed onto the entire device through the mounting holes 4 and mounting grooves 5 on the top plate 3. During use, when the top plate 3 is impacted, the top plate 3 moves downward, the cross arm 2 unfolds, and the downward movement of the top plate 3 drives the slide rod 62 to move downward. When the top plate 3 is impacted and moves downward, the buffer spring 63 absorbs the impact force and is gradually compressed. After the impact, the buffer spring 63 rebounds and returns to its original position. When the impact on the top plate 3 is large, the top plate 3 drives the support block 64 and the connecting frame 65 to move downward, and the contact block 68 will contact the deceleration block 611. At this time, the bottom of the contact block 68 will be deflected upward due to the force, and will not be squeezed too much with the deceleration block 611, thus avoiding resistance that would affect the buffer spring 63's absorption of the impact force. Subsequently, the torsion spring 67 rebounds and drives the contact block 68 to return to its original position. When the buffer spring 63 rebounds, the contact block 68 moves upward and contacts the deceleration block 611 again. 1. Upon contact, the presence of the limiting rod 69 prevents the contact block 68 from rotating downwards. The contact block 68 will compress with the deceleration block 611, generating significant resistance. This reduces the force of the buffer spring 63's rebound, preventing back-and-forth bouncing and improving the buffering effect. When the top plate 3 experiences a large impact, it will also cause the pressure chamber 72 to move downwards. The counterweight 74 will contact the top of the fixed plate 610. At this time, the piston rod 73 will move upwards relative to the pressure chamber 72, compressing the lubricating oil in the pressure chamber 72 and causing it to be sprayed out through the spray pipe 76. When the pressure chamber 72 moves upwards to return to its original position, the counterweight 74 will cause the piston rod 73 to move downwards to return to its original position. At this time, a negative pressure is formed in the pressure chamber 72, which will draw lubricating oil from the lubricating oil tank 71 through the suction pipe 75 and replenish the pressure chamber 72. The lubricating oil will be sprayed out through the spray pipe 76 to the sliding rod 62 and the buffer spring 63, lubricating the sliding rod 62 and the buffer spring 63 and slowing down the aging of their structure.
