Description

Technical Field

[0001] The utility model relates to the technical field of automobile seats, in particular to a force-bearing automobile seat with spring shock absorption. Background Art

[0002] When a car is in use, the car seat is used for passengers to sit. The seat provides support for the body to ensure that the passengers can maintain a relatively fixed position while the vehicle is driving. At the same time, a good car seat provides a comfortable sitting posture and support for passengers and drivers, making long-distance travel more comfortable. When the car encounters a bumpy road during driving, the vibration will still act on the driver through the seat.

[0003] A Chinese patent discloses a multifunctional car seat (authorization announcement number CN213056814U), which includes a car seat, a fixing plate, an umbrella placement bucket, a first table board, a second table board, an arc-shaped boss, a support rod placement platform, a rectangular ring-shaped support rod, a support rod fixing block and an elastic band; the beneficial effects of the utility model are: umbrellas can be stored through the umbrella placement bucket; through the cooperation between the first table board, the second table board, the arc-shaped boss, the support rod placement platform, the rectangular ring-shaped support rod, the support rod fixing block and the elastic band, the table top board can be used in the car to handle some simple tasks, and it is convenient to store and will not occupy a large amount of space in the car when not in use.

[0004] This patented technology provides an additional work surface when in use, but there are still some shortcomings in its use. When a car is driving on a bumpy road, the vibration will act on the passengers through the seat. The bump bar is strong, which reduces the comfort during driving and increases the fatigue of the passengers during driving. Therefore, those skilled in the art provide a spring-shock-absorbing force-bearing car seat to solve the problems raised in the above background technology. Utility Model Content

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] The utility model is a spring-shock-absorbing force-bearing automobile seat, comprising a seat structure.

[0008] The seat structure includes a seat frame, a seat plate located above the seat frame, and a support plate located inside the seat frame;

[0009] as well as;

[0010] The shock-absorbing structure includes a mounting tube, a bottom plate of a top plate located at the upper and lower sides of the mounting tube, a piston slidably mounted inside the mounting tube, a plug rod fixed to the lower end of the top plate and connected at the lower end to the upper end of the piston, a plurality of oil holes opened inside the piston, a valve block located at the opening of the oil hole, and a spring sleeved on the outer side of the mounting tube and connected at the upper and lower ends to the top plate and the bottom plate respectively.

[0011] Furthermore, a frame is provided on the lower side of the seat plate, and the lower end of the frame is slidably sleeved on the outer side of the seat frame;

[0012] Specifically, the seat plate is installed on the outer side of the seat frame through the frame sleeve, and the seat plate is effectively limited when moving longitudinally, thereby improving the stability of the seat plate during use.

[0013] Furthermore, a sealing ring is embedded and installed inside the upper end of the installation tube, the plug rod is slidably installed inside the sealing ring, and the lower end of the installation tube is provided with a rubber seat fixed on the upper end of the bottom plate;

[0014] Specifically, the plug rod is supported in a sealed sliding manner inside the upper end of the installation cylinder through the sealing ring, and a damping effect is applied to the installation cylinder through the rubber seat.

[0015] Furthermore, a valve stem connected to the valve block is arranged inside the oil hole, and a limiting rod distributed in a ring array is arranged on the outer wall of the valve stem;

[0016] Specifically, the movement of the plug rod in the oil hole drives the limit rod to move.

[0017] Furthermore, the length of the limit rod is greater than the radius of the oil hole, the valve block at the oil hole opening is located above and below the piston respectively, and the limit rod at the oil hole opening is located above and below the piston respectively;

[0018] Specifically, when the plug rod moves inside the oil hole, the limiting rod prevents one end of the plug rod from passing through the oil hole, thereby performing unidirectional limiting.

[0019] Furthermore, arc surfaces are provided at the openings at both the upper and lower ends of the oil hole;

[0020] Specifically, when the lubricating oil passes through the oil hole, the arc surface reduces the erosion of the lubricating oil on the oil hole opening, preventing the lubricating oil from impacting the oil hole for a long time and causing the generation of piston wear powder.

[0021] Furthermore, the shock absorbing structure and the seat frame are both provided with a docking structure, the docking structure includes docking holes, and the docking holes are located inside the four corners of the support plate, the lower end of the top plate is provided with a screw rod rotatably inserted into the docking hole, and the lower end of the support plate is provided with a nut rotatably sleeved on the outer wall of the screw rod;

[0022] Specifically, the bottom plate is inserted into the docking hole through a screw rod, and the bottom plate is fixed after a sleeve nut is rotated on the outer side of the screw rod at the lower end of the support plate.

[0023] Furthermore, the docking structure includes a slider, and the slider is located at the upper end of the top plate, fixed to the lower end of the seat plate and symmetrically distributed on the sliding seat, and the slider is slidably sleeved on the outer wall of the sliding seat;

[0024] Specifically, the top plate is slidably sleeved inside the sliding seat through a slider, and is conveniently docked with the seat plate when installed.

[0025] 2. Beneficial effects

[0026] Compared with the prior art, the advantages of the present invention are:

[0027] The utility model provides a sitting and standing requirement for passengers by sleeve-connecting a seat plate at the upper end of the seat frame, and the seat plate is fixedly connected to the support plate through a shock-absorbing structure. The seat plate and the support plate are reinforced with a frame structure made of plastic. These support structures can withstand the force from the spring and transmit it to other parts of the seat.

[0028] At the same time, when the vehicle is bumpy, the spring is forced to expand and contract. During this process, the piston moves inside the oil cylinder, squeezing the lubricating oil inside the mounting cylinder. When the lubricating oil passes through the oil hole, the narrow oil hole exerts resistance on the lubricating oil. The force opposite to the direction of piston movement acts as a damping agent on the spring, thereby cushioning the seat plate, reducing shock to the car seat, and improving the comfort of passengers when riding in the vehicle.

[0029] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] Example 1

[0045] See also Figure 1-Figure 5 As shown, this embodiment is a spring-shock-absorbing and force-bearing automobile seat, comprising a seat structure 100,

[0046] The seat structure 100 includes a seat frame 103, a seat plate 101 located above the seat frame 103, and a support plate 104 located inside the seat frame 103;

[0047] as well as;

[0048] The shock absorbing structure 200 includes a mounting tube 204, a bottom plate 205 of a top plate 201 located at the upper and lower sides of the mounting tube 204, a piston 208 slidably mounted inside the mounting tube 204, a plug rod 207 fixed at the lower end of the top plate 201 and connected at the lower end to the upper end of the piston 208, a plurality of oil holes 212 opened inside the piston 208, a valve block 209 located at the opening of the oil hole 212, and a spring 203 sleeved on the outside of the mounting tube 204 and connected at the upper and lower ends to the top plate 201 and the bottom plate 205 respectively.

[0049] The upper end of the installation cylinder 204 is embedded with a sealing ring 202, and the plug rod 207 is slidably installed inside the sealing ring 202. The lower end of the installation cylinder 204 is provided with a rubber seat 206 fixed on the upper end of the bottom plate 205;

[0050] A valve stem 210 connected to the valve block 209 is disposed inside the oil hole 212, and a limiting rod 211 distributed in a ring array is disposed on the outer wall of the valve stem 210;

[0051] The length of the limiting rod 211 is greater than the radius of the oil hole 212. The valve block 209 at the opening of the oil hole 212 is located above and below the piston 208, and the limiting rod 211 at the opening of the oil hole 212 is located above and below the piston 208.

[0052] Arc surfaces 213 are provided at the upper and lower openings of the oil hole 212;

[0053] Using the shock absorbing structure 200;

[0054] A soft cushion should also be placed on the seat plate 101 to improve the softness of sitting. When the vehicle travels on a bumpy road, the spring 203 is forced to jump up and down. During this process, the seat plate 101 moves up and down, driving the plug rod 207 to move longitudinally through the top plate 201, and the piston 208 moves longitudinally inside the mounting cylinder 204. The plug rod 207 is supported by the sealing ring 202 inside the upper end of the mounting cylinder 204 to prevent the lubricating oil inside the mounting cylinder 204 from leaking. The rubber seat 206 applies damping to the jumping spring 203 When the lubricating oil passes through the oil hole 212, the limit rod 211 prevents one end of the plug rod 207 from passing through the oil hole 212, and the valve blocks 209 at different oil holes 212 are located at the upper end or the lower end of the valve stem 210, so that the hydraulic oil can only pass through different oil holes 212 in one direction. The oil holes 212 exert resistance on the hydraulic oil, further damp the spring 203, and prevent the spring 203 from jumping. The spring 203 can stably expand and contract up and down, buffer the impact force of the bumpy driving of the car, play a shock-absorbing and buffering role, and improve the comfort of people when riding.
