Description

Technical Field

[0001] This utility model relates to the field of automotive seat technology, and in particular to a multifunctional automotive seat. Background Technology

[0002] As an important part of vehicle interior, car seats not only provide support for passengers but also directly affect the comfort and safety of driving and riding. Their design must fully consider ergonomics to provide good support and a sense of enclosure. With the development of the automotive industry, the function of seats has expanded from basic seating to integrating various comfort features such as adjustment, ventilation, and heating, becoming a key component for improving the overall quality of the vehicle and the user experience.

[0003] However, traditional car seats still have certain limitations in design. In particular, the headrest is usually a fixed shape or can only be adjusted in height and angle as a whole, and cannot be finely adjusted for the degree of protrusion in the neck area. It is difficult to match the actual physiological curvature of drivers of different body types. At the same time, the lumbar support is mostly fixed or has a limited range of adjustment. As a result, the neck and waist of passengers do not have effective and close support during long-distance driving, which can easily cause muscle fatigue and discomfort, affecting driving comfort and health. Utility Model Content

[0004] The purpose of this invention is to provide a multifunctional car seat that solves the problem of poor wrinkle resistance of traditional textile fabrics.

[0005] To achieve the above objectives, this utility model provides a multifunctional car seat, including a seat cushion, a fixing frame fixedly mounted at the bottom of the seat cushion, a backrest fixedly mounted on one side of the seat cushion, an angle adjustment device fixedly mounted between the backrest and the seat cushion, a headrest movably mounted at the top of the backrest, an elastic mesh fixedly mounted on the front side of the headrest, a headrest adjustment component inside the backrest, and a lumbar support adjustment component on the front side of the backrest. The seat cushion provides basic seating support, the fixing frame ensures the stability and installation strength of the overall seat structure, the backrest provides primary support for the passenger's back, the angle adjustment device allows for flexible changes in the backrest tilt angle to adapt to different sitting postures, the headrest supports the passenger's head, and the elastic mesh enhances the breathability and comfort of the front side of the headrest.

[0006] The headrest adjustment assembly includes a first knob, which is movably mounted on the side of the headrest away from the elastic mesh. A back plate is fixedly mounted inside the headrest. The first knob serves as the input device for headrest adjustment, and the back plate supports and fixes the internal structure.

[0007] The headrest has a rotating rod inside, which is fixedly connected to a first knob. A nut ring is fixedly installed at the end of the rotating rod away from the first knob. The rotating rod transmits rotational motion, and the nut ring is a key component that converts rotational motion into linear motion.

[0008] The headrest has an internally movable arc-shaped support block, and the outer ring of the arc-shaped support block is provided with a first sponge layer. The arc-shaped support block can directly change the contour of the headrest by moving linearly, and the first sponge layer wraps around the internal structure and provides a soft touch.

[0009] The inner wall of the slot inside the arc-shaped support block is fixedly provided with threads, the nut ring is engaged with the threads of the inner wall of the slot, and a limit end is fixedly provided at the edge of the slot. The threads and the nut ring cooperate to realize the conversion of the motion mode, and the limit end prevents excessive stroke during the adjustment process, thereby protecting the mechanism.

[0010] The lumbar support adjustment assembly includes a second knob, which is movably mounted on one side of the backrest. A bidirectional lead screw is rotatably mounted inside the backrest. The second knob is fixedly connected to the bidirectional lead screw, and two symmetrical ball nuts are movably mounted on the bidirectional lead screw.

[0011] The front side of the bidirectional lead screw is provided with an elastic plate, and a hinge frame is fixedly provided between the elastic plate and the ball nut.

[0012] The elastic plate has a surface layer fixedly disposed on its outer side, and a second sponge layer is fixedly disposed between the surface layer and the elastic plate.

[0013] Rotating the knob smoothly moves the internal mechanical structure, allowing for flexible adjustment of the headrest's front protrusion to perfectly adapt to different users' head curves and seating habits, providing a more comfortable head support and effectively relieving neck fatigue during long drives, thus enhancing overall comfort. Users can also control the internal symmetrical mechanism to move synchronously in the opposite direction by simply turning a dedicated knob, thereby changing the shape and support strength of the lumbar support to provide just the right amount of support for the lower back, adapting to various sitting postures and body types, significantly improving lumbar support during seating, and promoting healthy posture. All adjustments are made manually via the knob, requiring no external power, ensuring stable operation. The limiting mechanism effectively prevents damage from over-adjustment, guaranteeing the device's durability and long-term reliability, providing users with a user-friendly and reassuring comfort experience.

[0021] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0022] Please see Figures 1-5 A multifunctional car seat includes a seat cushion 1, a fixing frame 2 fixedly mounted at the bottom of the seat cushion 1, a backrest 3 fixedly mounted on one side of the seat cushion 1, an angle adjustment device 4 fixedly mounted between the backrest 3 and the seat cushion 1, a headrest 5 movably mounted at the top of the backrest 3, an elastic mesh 6 fixedly mounted on the front side of the headrest 5, a headrest adjustment component inside the backrest 3, and a lumbar support adjustment component on the front side of the backrest 3. The seat cushion 1 provides basic support for the occupant, the fixing frame 2 is used to fix and install the entire seat structure, the backrest 3 provides support for the occupant's back, the angle adjustment device 4 allows for adjustment of the tilt angle of the backrest 3, the headrest 5 is used to support the head, the elastic mesh 6 enhances the breathability and comfort of the front side of the headrest 5, and the headrest adjustment component is responsible for adjusting the shape of the headrest 5.

[0023] The headrest adjustment assembly includes a first knob 7. The first knob 7 is movably mounted on the side of the headrest 5 away from the elastic mesh 6. A back plate 8 is fixedly mounted inside the headrest 5. A rotating rod 9 is rotatably mounted inside the headrest 5. The rotating rod 9 is fixedly connected to the first knob 7. A nut ring 10 is fixedly mounted on the end of the rotating rod 9 away from the first knob 7. An arc-shaped support block 11 is movably mounted inside the headrest 5. A first sponge layer 12 is mounted on the outer ring of the arc-shaped support block 11. A thread 13 is fixedly mounted on the inner wall of the groove inside the arc-shaped support block 11. The nut ring 10 is engaged with the thread 13 on the inner wall of the groove. A limit end 14 is fixedly mounted at the edge of the groove. The rotating rod 9 transmits the rotational movement of the first knob 7. The nut ring 10 converts the rotational movement of the rotating rod 9 into linear movement. The arc-shaped support block 11 changes the degree of protrusion of the front of the headrest 5 through linear movement. The first sponge layer 12 provides a soft touch. The engagement of the thread 13 with the nut ring 10 realizes the movement conversion. The limit end 14 prevents the arc-shaped support block 11 from moving excessively.

[0024] The lumbar support adjustment assembly includes a second knob 15. The second knob 15 is movably mounted on one side of the backrest 3. A bidirectional lead screw 16 is rotatably mounted inside the backrest 3. The second knob 15 is fixedly connected to the bidirectional lead screw 16. Two symmetrical ball nuts 17 are movably mounted on the bidirectional lead screw 16. An elastic plate 18 is mounted on the front side of the bidirectional lead screw 16. A hinge frame 19 is fixedly mounted between the elastic plate 18 and the ball nuts 17. A surface layer 20 is fixedly mounted on the outer side of the elastic plate 18. A second sponge layer 21 is fixedly mounted between the surface layer 20 and the elastic plate 18. The lumbar support adjustment assembly is responsible for adjusting the lumbar support. It includes a second knob 15 that receives user input. The bidirectional lead screw 16 converts rotational motion into symmetrical linear motion. The ball nuts 17 move linearly along the bidirectional lead screw 16. The hinge frame 19 transmits the motion of the ball nuts 17 to the elastic plate 18. The elastic plate 18 bends and deforms to change the shape of the lumbar support protrusion. The surface layer 20 serves as the contact surface with the human body, and the second sponge layer 21 provides cushioning and softness.

[0025] Working principle: By rotating the first knob 7, the rotating rod 9, which is fixed to it, can be rotated synchronously. The rotating rod 9 further drives the nut ring 10 to rotate in the groove reserved inside the arc-shaped support block 11. Since the nut ring 10 and the thread 13 machined on the inner wall of the groove are interlocked, the thread meshing generated during the rotation converts the rotational motion into a precise linear movement of the arc-shaped support block 11 along its axial direction. By controlling the forward and reverse rotation direction of the first knob 7, the extension or retraction state of the arc-shaped support block 11 can be flexibly adjusted, thereby changing the degree of protrusion of the part of the headrest 5 covered by the first sponge layer 12, effectively adapting to the head curve and support preferences of different drivers, and effectively relieving neck fatigue during long-distance driving. In this mechanism, the limiting end 14 plays a key protective role, which prevents the arc-shaped support block 11 from moving through a mechanical limiting method. Excessive travel causes the nut ring 10 to disengage from the thread 13, ensuring a stable and reliable adjustment process. In addition, users can also adjust the lumbar support effect by rotating the second knob 15 located on the side of the backrest 3. The rotation of the second knob 15 will drive the connected bidirectional lead screw 16 to rotate synchronously. The two ball nuts 17 symmetrically arranged on the bidirectional lead screw 16 move away from or towards each other along the lead screw axis under the thread drive. The movement of the ball nuts 17 further pushes the elastic plate 18 to undergo controllable elastic bending deformation through the hinge frame 19. The degree of bending of the elastic plate 18 directly determines the height of the lumbar support area formed by the surface layer 20 and the second sponge layer 21, thereby providing precise and adjustable lumbar support for the occupant, significantly improving the fit and comfort of the seat, and meeting the lumbar health sitting posture needs of users of different body types.

[0026] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
