Description

Technical Field

[0001] This utility model relates to the field of damping adjustment technology, specifically to an electric damping adjustment mechanism for automobile seats. Background Technology

[0002] Currently, most large cars on the market are equipped with car seat shock absorption mechanisms, which use scissor frames, dampers and other structures to form a shock absorption system, improve the seat's absorption of vibration, enhance the smoothness of the driving process, and thus increase the comfort of the seat.

[0003] The damper in a car seat's shock absorption system is a key component for seat damping, and it is generally divided into two types: fixed dampers and adjustable dampers. Currently, the damping force of fixed dampers installed in car seats is fixed, and passengers cannot adjust the damping force according to their needs, which affects seat comfort. Adjustable dampers, on the other hand, allow for adjustment of the damping force using adjustment buttons installed on the car seat, thereby improving passenger comfort. However, existing car seat dampers have limited adjustment levels and cannot be fine-tuned, preventing passengers from adjusting the damper to the most suitable damping state. Furthermore, when making large-scale damping adjustments, passengers can only adjust one level at a time, a cumbersome and inconvenient process. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide an electric damping adjustment mechanism that can infinitely adjust the damping of the damper on the car seat and is simple and sensitive to operate.

[0005] The technical solution of this utility model is to provide an electric damping adjustment mechanism for automobile seats with the following structure:

[0006] The device includes a first scissor lift, a second scissor lift, and an adjustable damper. The first and second scissor lifts are hinged together, and the two ends of the adjustable damper are respectively hinged to the first and second scissor lifts. A damping adjustment assembly is connected to one end of the adjustable damper near its damping adjustment rod. The damping adjustment assembly includes a horizontal drive motor and a transmission component connected to the output end of the horizontal drive motor. One side wall of the transmission component extends toward the damping adjustment rod and forms a transmission handle, which is movably connected to the damping adjustment rod. The horizontal drive motor drives the transmission component to move horizontally, and the transmission component drives the damping adjustment rod to rotate circumferentially through the transmission handle.

[0007] Preferably, the free end of the transmission handle is provided with a connecting hole for the damping adjustment rod to pass through. The diameter of the connecting hole is larger than the outer diameter of the damping adjustment rod, so that the damping adjustment rod is fitted with a clearance within the connecting hole.

[0008] Preferably, there are multiple connecting holes, which are spaced apart along the length of the transmission handle.

[0009] Preferably, the damping adjustment assembly further includes a mounting base fixedly connected to the end of the adjustable damper and a cover plate detachably connected to the mounting base, and the horizontal drive motor is fixedly installed inside the mounting base.

[0010] Preferably, the mounting base is provided with a guide rod parallel to the transmission direction of the horizontal drive motor, and the transmission component is slidably connected to the guide rod.

[0011] Preferably, the second scissor lift has a connecting shaft in the middle, one end of the adjustable damper is hinged to the end of the first scissor lift, and the other end is hinged to the connecting shaft on the second scissor lift.

[0012] After adopting the above structure, the electric damping adjustment mechanism for automobile seats in this utility model has the following advantages compared with the prior art:

[0013] 1. This utility model uses a horizontal drive motor to drive the transmission component to move horizontally, which in turn drives the damping adjustment rod to rotate circumferentially through the transmission handle; the transmission of the horizontal drive motor is more delicate and smooth, not limited by gears, and can realize stepless adjustment of the damping adjustment rod, which is convenient for drivers and passengers to fine-tune the damper; in addition, when making large-span damping adjustments, it can be adjusted directly to the position, making the operation simpler and more sensitive.

[0014] 2. Since the damping adjustment rod adjusts the damping magnitude by rotating circumferentially, while the transmission handle moves horizontally, in order to avoid transmission jamming, the damping adjustment rod needs to be fitted with a clearance fit in the connecting hole so that the damping adjustment rod will not be jammed within a certain rotation angle. This allows users to freely adjust the damping force of the adjustable damper to achieve a suitable damping state, thereby improving the ride comfort of the driver and passengers.

[0015] 3. The mounting base and cover plate work together to protect the damping adjustment assembly. The damping adjustment rod is also located inside the mounting base, preventing the damping adjustment of the adjustable damper from being affected.

[0016] 4. The guide rod has a guiding function, which can prevent radial offset of the transmission components during movement. Attached Figure Description

[0023] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0024] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. At the same time, the terms "first", "second", etc., are only used to distinguish the names of various components and do not have a primary or secondary relationship. Therefore, they should not be construed as limitations on this utility model.

[0025] like Figures 1-4 As shown, this utility model discloses an electric damping adjustment mechanism for automobile seats, comprising a first scissor lift 1, a second scissor lift 2, and an adjustable damper 3. The first scissor lift 1 is hinged to the middle of the second scissor lift 2, and a connecting shaft 21 is provided in the middle of the second scissor lift 2. One end of the adjustable damper 3 is hinged to one end of the first scissor lift 1, and the other end is hinged to the connecting shaft 21 on the second scissor lift 2.

[0026] The adjustable damper 3 has a damping adjustment component 4 connected to one end near its damping adjustment rod 31. The damping adjustment component 4 is connected to the damping adjustment rod 31 in a transmission manner and is used to drive the damping adjustment rod 31 to rotate circumferentially, thereby adjusting the damping magnitude.

[0027] like Figures 2-4As shown, the damping adjustment assembly 4 includes a horizontal drive motor 41 and a transmission component 42 connected to the output end of the horizontal drive motor 41. One side wall of the transmission component 42 extends toward the damping adjustment rod 31 and forms a transmission handle 421. The free end of the transmission handle 421 is provided with a connecting hole 422 through which the damping adjustment rod 31 passes. The diameter of the connecting hole 422 is larger than the outer diameter of the damping adjustment rod 31, so that the damping adjustment rod 31 is clearance-fitted into the connecting hole 422.

[0028] This utility model uses a horizontal drive motor 41 to drive the transmission component 42 to move horizontally, which in turn drives the damping adjustment rod 31 to rotate circumferentially through the transmission handle 421. Since the transmission of the horizontal drive motor 41 is more delicate and smooth, and is not limited by gears, the damping adjustment rod 31 can be infinitely adjusted, making it convenient for drivers and passengers to fine-tune the damper. In addition, when making large-span damping adjustments, it can be adjusted directly to the position, making the operation simpler and more sensitive.

[0029] The horizontal drive motor 41 can be a stepper motor or a linear motor, driving the transmission component 42 to move in a horizontal linear direction. Since the damping adjustment rod 31 adjusts the damping by rotating circumferentially, and the transmission handle 421 moves horizontally with the transmission component 42, in order to avoid transmission jamming, the damping adjustment rod 31 needs to be fitted with the connecting hole 422 with clearance, so that the damping adjustment rod 31 and the transmission handle 421 are movably connected. Therefore, during the transmission process, the damping adjustment rod 31 will not be jammed within the set rotation angle, so that the user can freely adjust the damping of the adjustable damper 3.

[0030] The horizontal drive motor 4 can be connected to the vehicle control system, allowing users to manually adjust the damping magnitude; the vehicle control system can also be equipped with detection components to automatically adjust the damping magnitude according to the vehicle's bumpy conditions.

[0031] like Figure 4 As shown, there are two connecting holes 422 on the transmission handle 421, which are spaced apart along the length of the transmission handle 421. This allows the user to select one of the connecting holes 422 to pass the damping adjustment rod 31 through, depending on the specific installation position of the damping adjustment component 4. The two connecting holes 422 can also have different diameters, which can determine the range of rotation angle of the damping adjustment rod 31.

[0032] The damping adjustment assembly 4 also includes a mounting base 43 fixedly connected to the end of the adjustable damper 3 and a cover plate 44 snap-fitted onto the mounting base 43. A receiving cavity is formed between the mounting base 43 and the cover plate 44, and the horizontal drive motor 41 is fixedly installed in the receiving cavity of the mounting base 43. The cooperation between the mounting base 43 and the cover plate 44 can protect the damping adjustment assembly 4, and the damping adjustment rod 31 is also located inside the mounting base 43 to prevent the damping adjustment of the adjustable damper 3 from being affected by external factors. The mounting base 43 is fixed to the end of the adjustable damper 3. When the adjustable damper 3 rotates, the mounting base 43 and the damping adjustment assembly 4 inside it will also rotate synchronously. The relative position of the transmission handle 421 and the damping adjustment rod 31 is not affected. The damping magnitude will only be adjusted when the horizontal drive motor 41 drives the damping adjustment rod 31 to rotate.

[0033] The mounting base 43 is provided with a guide rod 45 parallel to the transmission direction of the horizontal drive motor 41. The transmission component 42 is slidably connected to the guide rod 45, which guides the transmission of the transmission component 42 and prevents the transmission component 42 from radially deviating during horizontal movement.

[0034] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
