Abstract
Description
Technical Field
[0001] This utility model relates to the field of seat damper technology, specifically an adjustable car seat damper. Background Technology
[0002] A seat damper is a mechanical device installed in the structure of a car seat. Its core function is to absorb and dissipate energy by generating resistance, thereby slowing down the movement of components and preventing violent shaking caused by sudden movements or external impacts (such as vehicle bumps, acceleration or braking).
[0003] The installation position of the car seat damper is fixed. The contact area is different for light-weight people and heavy-weight people. It cannot sense and respond to the differences in weight, sitting posture and actual contact area and pressure distribution of different occupants. The damper adjustment is seriously mismatched with the needs, and the lack of pressure distribution creates adjustment blind spots. It is difficult to achieve precise support, resulting in a decrease in seat comfort and stability and poor adaptability.
[0004] Therefore, this utility model provides an adjustable car seat damper to solve the above problems. Utility Model Content
[0005] (a) Technical problems to be solved
[0006] This invention provides an adjustable car seat damper, which aims to solve the problems mentioned in the background art.
[0007] (II) Technical Solution
[0008] To achieve the above objectives, this utility model provides the following technical solution: an adjustable car seat damper, comprising a seat body, two fixed frames arranged above the seat body, a plurality of first dampers arranged between the two fixed frames, a plurality of sliding grooves opened on one side of the fixed frame, a slider slidably connected to the inner cavity of the sliding groove, a plurality of second dampers arranged between the two fixed frames, a plurality of side plates fixedly connected to the top of one of the fixed frames, and an electric push rod fixedly installed on one side of the side plate.
[0009] As a preferred technical solution of this application, the top and bottom of the first damper are respectively fixedly connected to one side of the corresponding fixed frame, and the top and bottom of the second damper are respectively fixedly connected to one side of the corresponding slider.
[0010] As a preferred technical solution of this application, one side of a plurality of corresponding sliders is fixedly connected to one side of an adjacent connecting plate, and the output end of the electric push rod is fixedly connected to one side of the corresponding connecting plate.
[0011] As a preferred technical solution of this application, the bottom of the inner cavity of the seat body is rotatably connected to a threaded cylinder via a rotating shaft, and the inner cavity of the threaded cylinder is connected to a threaded post via a thread, the top of the threaded post being fixedly connected to the bottom of the corresponding fixing frame.
[0012] As a preferred technical solution of this application, a drive motor is fixedly installed on one inner wall of the seat body, the output shaft of the drive motor is fixedly connected to a rotating rod, and a first bevel gear is sleeved on the outer ring of the rotating rod.
[0013] As a preferred technical solution of this application, the outer ring of the threaded cylinder is fitted with a second bevel gear, and the first bevel gear and the second bevel gear are engaged by a snap-tooth meshing.
[0014] As a preferred technical solution of this application, guide cylinders are fixedly connected to the four corners of the bottom of the inner cavity of the seat body, guide columns are slidably connected to the inner cavity of the guide cylinders, the top of the guide columns are fixedly connected to the bottom of the corresponding fixing frame, springs are fixedly connected to the bottom of the inner cavity of the guide cylinders, the top of the springs are fixedly connected to the bottom of the corresponding guide columns, and a seat cushion is fixedly connected to the upper surface of one of the fixing frames.
[0015] (III) Beneficial Effects
[0016] By coordinating the electric push rod, connecting plate, fixing bracket, slider, and slide groove, the distance between the second damper and the first damper can be adjusted. This allows for dynamic adjustment of the damping force distribution area based on the occupant's actual sitting posture and the contact area with the seat cushion. This avoids excessive local pressure or insufficient support caused by different contact areas, ensuring that lighter individuals do not experience discomfort due to excessive damping, and heavier individuals do not experience blind spots due to unreasonable damping distribution. This improves the adaptability and accuracy of damping adjustment, enhances the comfort and stability of the seat, and provides strong adaptability.
[0017] By using a drive motor, rotating rod, first bevel gear, second bevel gear, threaded cylinder, and threaded column, the seat height can be adjusted to a height suitable for the occupant's current sitting posture. This allows the seat to better conform to the occupant's body curves, reducing driving fatigue caused by poor posture. In conjunction with the guide cylinder, guide column, and spring, the movement direction is effectively constrained, preventing the seat from tilting during lifting and lowering, and ensuring the smoothness and accuracy of the adjustment process.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0025] This utility model provides an adjustable car seat damper, such as... Figure 1 - Figure 4 As shown, the technical solution includes a seat body 1, with two fixing frames 3 on the top of the seat body 1, and a number of first dampers 6 between the two fixing frames 3. A number of sliding grooves 14 are opened on one side of the fixing frame 3, and a slider 15 is slidably connected to the inner cavity of the sliding groove 14. A number of second dampers 16 are arranged between the two fixing frames 3. A number of side plates 19 are fixedly connected to the top of one of the fixing frames 3, and an electric push rod 17 is fixedly installed on one side of the side plate 19.
[0026] The top and bottom of the first damper 6 are fixedly connected to one side of the corresponding fixed frame 3, and the top and bottom of the second damper 16 are fixedly connected to one side of the corresponding slider 15. When the electric push rod 17 pushes the connecting plate 18, the slider 15 slides in the slide groove 14, causing the second damper 16 to change its relative position with the first damper 6, thereby achieving the effect of adjustable damping force distribution. This allows the seat body 1 to adjust the support focus area according to the occupant's sitting posture, improving the flexibility and adaptability of local support.
[0027] One side of each of the corresponding sliders 15 is fixedly connected to one side of the adjacent connecting plate 18, and the output end of the electric push rod 17 is fixedly connected to one side of the corresponding connecting plate 18. The electric push rod 17 provides the power to push the connecting plate 18.
[0028] The bottom of the inner cavity of the seat body 1 is rotatably connected to a threaded cylinder 5 via a rotating shaft. The inner cavity of the threaded cylinder 5 is connected to a threaded post 11 via a thread. The top of the threaded post 11 is fixedly connected to the bottom of the corresponding fixed frame 3. When the threaded cylinder 5 rotates, it drives the threaded post 11 to move up and down. The lifting motion is transmitted to the connected fixed frame 3, thereby driving the seat cushion 2 to lift as a whole.
[0029] A drive motor 7 is fixedly installed on one inner wall of the seat body 1. The output shaft of the drive motor 7 is fixedly connected to a rotating rod 8. A first bevel gear 9 is sleeved on the outer ring of the rotating rod 8. The drive motor 7 provides the rotation power to the rotating rod 8.
[0030] The outer ring of the threaded cylinder 5 is fitted with a second bevel gear 10. The first bevel gear 9 and the second bevel gear 10 are meshed through a snap-tooth engagement. The output shaft of the drive motor 7 drives the rotating rod 8 to rotate, thereby driving the first bevel gear 9 to rotate. The power is transmitted to the second bevel gear 10 through the snap-tooth engagement, thereby driving the threaded cylinder 5 to rotate, driving the threaded column 11 to rotate, and realizing the vertical displacement of the connected fixed frame 3.
[0031] Guide cylinders 4 are fixedly connected to the four corners of the bottom of the inner cavity of the seat body 1. Guide columns 13 are slidably connected to the inner cavity of the guide cylinders 4. The top of the guide column 13 is fixedly connected to the bottom of the corresponding fixed frame 3. Springs 12 are fixedly connected to the bottom of the inner cavity of the guide cylinders 4. The top of the springs 12 is fixedly connected to the bottom of the corresponding guide columns 13. A seat cushion 2 is fixedly connected to the upper surface of one of the fixed frames 3. During the lifting and lowering process of the fixed frame 3, the guide column 13 slides along the inner wall of the guide cylinder 4. The spring 12 is stretched when the fixed frame 3 rises, which plays a guiding and anti-deviation role, ensuring the stability and straightness of the lifting and lowering process.
[0032] Specifically: When a person uses the seat body 1, during damping adjustment, the extension and retraction of the electric push rod 17 is activated by controlling its switch. The output end of the electric push rod 17 pushes the connecting plate 18, and the connecting plate 18 drives the slider 15 to slide synchronously within the slide groove 14. The second damper 16 undergoes lateral displacement along with the slider 15, thereby changing the relative distance between the second damper 16 and the first damper 6. By adjusting this distance, the damping force in different areas of the seat body 1 is redistributed, making the damping point closer to the parts of the occupant's body with greater pressure. After completing the damping distribution adjustment, if it is necessary to adjust the height of the seat cushion 2 to obtain better leg support or visibility, the person starts the drive motor 7. The output shaft of the drive motor 7 drives the rotating rod 8 to rotate, which in turn drives the first bevel gear 9 to rotate. The rotation of the first bevel gear 9 drives the meshing second bevel gear 10 to rotate, which in turn drives the threaded cylinder 5 to rotate. The rotation of the threaded cylinder 5 is converted into the linear lifting and lowering motion of the threaded column 11, thereby driving the connected fixed frame 3 to rise or fall. At the same time, the guide column 13 slides synchronously in the guide cylinder 4 to ensure the smoothness and linearity of the lifting and lowering process. The spring 12 set at the bottom of the guide cylinder 4 undergoes stretching or compression deformation during the lifting and lowering of the guide column 13, which plays a role in resetting. Ultimately, the overall height of the seat cushion 2 can be precisely adjusted to meet the comfort needs of the person.
[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
