Description
Technical Field
[0001] This utility model relates to the field of automotive seat technology, specifically to a seat with a scale-adjustable handwheel device. Background Technology
[0002] Currently, most mechanical shock-absorbing seat adjustment handwheels only have an increase or decrease indicator function, and cannot be precisely adjusted to the appropriate position according to the needs of the occupants. In addition, mechanical shock-absorbing adjustment screws vary in length, and even if they have scales, they cannot achieve as much universality as possible. At present, there is a great demand for this structure in the market. Summary of the Invention
[0003] To address the aforementioned problems, the purpose of this invention is to provide a seat with a scale-adjustable handwheel device.
[0004] To achieve the above objectives, the technical solution of this utility model is as follows: a seat with a scale adjustment handwheel device, comprising a fixed base and a rotating outer shell rotatably disposed around the fixed base. A rotating shaft rotatably passes through the fixed base, and the outer end of the rotating shaft is fixedly connected to the center of a circular transparent dial covering the outer side of the fixed base. The outer edge of the transparent dial is fixedly connected to the inner edge of the rotating outer shell. Rotating the rotating outer shell drives the rotating shaft to rotate on the fixed base via the transparent dial. The inner end of the rotating shaft is then connected to a lead screw on the seat to achieve the adjustment function. Multiple fixed shafts are fixed on the outer side of the fixed base, one of which is fitted with a freely rotatable intermediate gear. A circular digital dial is also provided between the fixed base and the transparent dial. The central opening of the digital dial is fitted onto a cylinder extending inward from the transparent dial, allowing the digital dial to rotate around the cylinder. An inner ring gear that meshes with the outer side of the intermediate gear is provided on the inner edge of the digital dial. A toothed plate with one tooth is fixed to the inner end of the cylinder, and the tooth of the toothed plate meshes with the intermediate gear.
[0005] Furthermore, the top edge of the fixed chassis is provided with pointers that extend to the surface of the digital dial.
[0006] Furthermore, the fixed chassis is installed and connected to the seat frame via a handwheel fixing plate on the inner side.
[0007] Furthermore, the seat frame has an L-shaped structure, and two guide rods are fixed to the back of the fixed chassis, running through the outer wall of the seat frame.
[0008] Furthermore, the rotating shaft consists of two parts, an inner and an outer part. The outer part is provided with a sliding sleeve that fits onto the inner part. The upper and lower side walls of the sliding sleeve are respectively provided with elongated sliding holes arranged along the axis of the rotating shaft. The upper and lower ends of the outer part of the inner part of the rotating shaft are respectively fixedly connected to limit posts, and the upper and lower limit posts are respectively located in the elongated sliding holes.
[0009] Furthermore, the outer end of the rotating shaft is a hexagonal prism structure that penetrates the center of the transparent dial and is fixedly connected to it.
[0010] Furthermore, a bearing sleeve is provided at the part of the rotating shaft that passes through the seat frame.
[0011] With the above settings, when this utility model is in use, the operator rotates the rotating outer shell, which drives the transparent dial and the rotating shaft to move in a circular motion. The toothed plate at the inner end of the transparent dial cooperates with the intermediate gear, thereby causing the intermediate gear to rotate. The intermediate gear drives the digital dial to rotate, while the pointer on the fixed base remains stationary. There are three fixed shafts where the intermediate gear can be freely installed, and the number of gears can be freely matched as needed, thereby achieving different rotational speeds of 1-3 teeth rotation of the digital dial for every one revolution of the rotating outer shell.
[0012] This invention not only accurately displays the weight level that the shock-absorbing seat needs to be adjusted through a digital dial, clearly indicating the upper and lower limits of the adjustment device, but also features a rotatable digital dial inside the transparent dial, with an optimized appearance compared to traditional handwheels. In addition, the fixed chassis has three fixed shafts where gears can be freely installed, thus enabling the adjustment of different rotation speeds without redevelopment, adapting to different shock-absorbing adjustment stroke devices to meet diverse market demands.

[0015] like Figure 1-5As shown, a seat adjustment handwheel device includes a fixed base 7 and a rotating housing 3 rotatably disposed around the fixed base 7. A rotating shaft 6 rotatably passes through the fixed base 7, and the outer end of the rotating shaft 6 is fixedly connected to the center of a circular transparent dial 1 covering the outer side of the fixed base 7. The outer edge of the transparent dial 1 is fixedly connected to the inner edge of the rotating housing 3. Rotating the rotating housing 3, in turn, drives the rotating shaft 6 to rotate on the fixed base 7 via the transparent dial 1. The inner end of the rotating shaft 6 is then connected to a lead screw on the seat to achieve the adjustment function. Multiple fixed shafts 8 are fixed to the outer side of the fixed base 7, one of which is fitted with a freely rotatable... A circular digital dial 2 is also provided between the intermediate gear 4, the fixed base 7, and the transparent dial 1. The central opening of the digital dial 2 is fitted onto the cylinder 9 extending inward from the transparent dial 1, allowing the digital dial 2 to rotate around the cylinder 9. An inner ring gear 10 that meshes with the outer side of the intermediate gear 4 is provided on the inner edge of the digital dial 2. A toothed plate 11 with one tooth is fixed at the inner end of the cylinder 9, and the tooth of the toothed plate 11 meshes with the intermediate gear 4. A pointer 12 extending to the surface of the digital dial 2 is provided on the top edge of the fixed base 7. The fixed base 7 is installed and connected to the seat frame 13 via a handwheel fixing plate 5 on its inner side.
[0016] To facilitate the extension of the rotating outer shell 3, digital dial 2, etc., and thus make it easy to rotate and adjust at the bottom of the seat, the seat frame 13 has an L-shaped structure, and two guide rods 14 are fixed to the back of the fixed chassis 7, passing through the outer wall of the seat frame 13. The rotating shaft 6 consists of two parts, an inner and an outer part. The outer part is provided with a sliding sleeve 15 that fits on the inner part. The upper and lower side walls of the sliding sleeve 15 are respectively provided with long strip-shaped sliding holes 16 arranged along the axis of the rotating shaft 6. The upper and lower limit posts 17 are respectively fixedly connected to the outer ends of the inner part of the rotating shaft 6, and the upper and lower limit posts 17 are respectively located in the long strip-shaped sliding holes 16.
[0017] The outer end of the rotating shaft 6 is a hexagonal prism structure, which passes through the center of the transparent dial 1 and is fixedly connected to the transparent dial 1 for easy installation. The outer end of the rotating shaft 6 and the transparent dial 1 form a synchronous and coaxial rotating structure. A bearing sleeve is provided at the part of the rotating shaft 6 that passes through the seat frame 13 to make the rotating shaft 6 rotate smoothly.
[0018] The working principle of this utility model is as follows: When working, the handwheel fixing plate 5 is welded to the seat frame. The operation of the rotating outer shell 3 drives the transparent dial 1 and the rotating shaft 6 to rotate. The transparent dial 1 rotates synchronously, causing the toothed plate 11 fixed at the inner end to rotate. The toothed plate 11 drives the intermediate gear 4 to rotate, which in turn drives the digital dial 2 to rotate. The fixed base 7 cannot rotate because it is in cooperation with the handwheel fixing plate, and the injection-molded pointer 12 on it is also fixed in place. The rotation of the rotating outer shell 3 and the transparent dial 1 drives the rotating shaft 6 and the toothed plate 1 to rotate one revolution. Different rotation speeds of 1-3 divisions of the dial value can be achieved by matching different numbers of intermediate gears 4, which makes it convenient to select different numbers of intermediate gears 4 according to user needs. In addition, there are two guide rods 14 on the back of the fixed chassis 7, which cooperate with the fixed handwheel fixing plate 5 to prevent the fixed chassis 7 from rotating relative to the seat. Pulling the fixed chassis 7, rotating housing 3, digital dial 2, etc. outward, they slide outward along the guide rods 14. At the same time, the outer end of the rotating shaft 6 slides along its other part, i.e., the inner end. Since the upper and lower ends of the inner part of the rotating shaft 6 are fixedly connected to the upper and lower limit posts 17, and the upper and lower limit posts 17 are respectively located in each long strip sliding hole 16, a sliding limit structure is formed, which can realize the back and forth pull adjustment function of the handwheel adjustment part (i.e., the internal structure of the rotating housing 3).
[0019] The above description is merely an illustrative embodiment of this utility model and is not intended to limit the scope of this utility model. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of this utility model should fall within the protection scope of this utility model.
