[0032] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0033] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0034] Example 1 Please refer to Figure 1 , Figure 15 As shown, a mechanical sliding lifting massage device is installed inside a car seat, specifically as a seat back 21. The seat back 21 includes a seat foam 14, a seat frame 19 is installed inside the seat foam 14, and a cover is wrapped around the seat foam 14. The mechanical sliding lifting massage device is installed inside the seat foam 14. like Figures 2 to 8 As shown, the mechanical sliding lifting massage device includes: The back plate 1 has two through holes 2, which are parallel to each other, and the two sides of the back plate 1 are the first side and the second side, respectively. The lifting device includes a connecting rod assembly arranged in a row and corresponding to the two strip holes 2. The connecting rod assembly includes a first connecting rod 3 and a second connecting rod 4 that are hinged together. The ends of the first connecting rod 3 and the second connecting rod 4 that are far apart are the first end and the second end, respectively. The second connecting rod 4 is also provided with a lifting head 5. A driving device is used to drive the lifting device to bring the first end and the second end closer together, so that the lifting head 5 moves away from the back plate 1 to achieve massage. The strip-shaped hole 2 extends along a first direction, and the back plate 1 also extends along a first direction. The strip-shaped hole 2 is used to accommodate the first connecting rod 3 and the second connecting rod 4. The first direction is... Figure 5 In the vertical direction; the back panel 1 is set on the seat frame 19, and a spring frame 20 is provided on the back panel 1 to support the back panel 1 and provide shock absorption; Furthermore, the first link 3 has a first end and a first hinge end, the second link 4 has a second end and a second hinge end, the first hinge end and the second hinge end are hinged together, and a lifting head 5 is also provided on the side of the second link 4 located away from the first end from the first hinge end. Therefore, when the first end and the second end are close together, the lifting head 5 moves away from the back plate 1 to lift the face cover, thereby realizing the massage function.

[0035] The lifting device also includes a slider assembly, which is movably mounted on the back plate 1. The slider assembly includes: The first slider 6 is movably disposed on the first side, and the first end extends through the strip hole 2 to the first side and is rotatably connected to the first slider 6. The second slider 7 is movably disposed on the first side, and the second end extends through the strip hole 2 to the first side and is rotatably connected to the second slider 7. The first slider 6 and the second slider 7 are arranged in a first direction and can move relative to each other in the first direction so that the first end and the second end can move relative to each other; the first slider 6 is located below the second slider 7; It should be noted that each of the first slider 6 and the second slider 7 has one, with both first ends rotatably connected to the first slider 6 and both second ends rotatably connected to the second slider 7. Furthermore, both the first and second ends are provided with rotating shafts, thereby achieving a rotatable connection with the first slider 6 and the second slider 7.

[0036] To ensure the smooth movement of the first slider 6 and the second slider 7, a guide rod 8 extending in the first direction is provided on the first side. The guide rod 8 is slidably connected to the first slider 6 and the second slider 7 to guide the movement of the first slider 6 and the second slider 7. Thus, through the driving action of the driving device, the first slider 6 and the second slider 7 move closer to each other, the first end and the second end move closer to each other, and the first hinge end and the second hinge end rotate, so that the lifting head 5 can move away from the back plate 1 and lift the face cover to achieve massage.

[0037] The driving device includes a first driving member 9 and a second driving member 10, which are respectively disposed on both sides of the first side and are used to drive the first slider 6 and the second slider 7 to move. Furthermore, a pulley 11 is rotatably provided on the first side, with its axis perpendicular to the first direction; The driving device also includes a first flexible traction member 12 and a second flexible traction member 13. The two ends of the first flexible traction member 12 are respectively connected to the two ends of the first slider 6 in the first direction. The first flexible traction member 12 is connected to the first driving member 9. One end of the second flexible traction member 13 is connected to the second driving member 10, and the other end passes around the pulley 11 and connects to the second slider 7. The first flexible traction member 12 and the second flexible traction member 13 can be flexible traction elements such as ropes, pulleys, and belts.

[0038] In this configuration, both the first driving member 9 and the second driving member 10 can be selected as speed reducers, both ends of the first flexible traction member 12 are connected to the first slider 6, and the first flexible traction member 12 can be selected to be wound around the driving end of the first driving member 9, thereby realizing the transmission connection. It should be noted that the first flexible traction member 12 has a first part and a second part. The first part is located above the first driving member 9, and the second part is located below the first driving member 9. When the driving end of the first driving member 9 rotates clockwise, the first part shortens and the second part lengthens, thereby lifting the first slider 6 upward and enabling the first slider 6 to move closer to the second slider 7. When the driving end of the first driving member 9 rotates counterclockwise, the second part shortens and the first part lengthens, enabling the first slider 6 to move away from the second slider 7. One end of the second flexible traction member 13 is connected to the second driving member 10, and the other end passes around the pulley 11 and connects to the second slider 7, thereby realizing the transmission connection. When the driving end of the second driving member 10 rotates, it realizes the winding of the second flexible traction member 13, thereby pulling the second slider 7 to move closer to the first slider 6. When the driving end of the second driving member 10 reverses, during the process of the first slider 6 moving away from the second slider 7, and under the action of the force applied by the human body to the face cover, the second slider 7 can move away from the first slider 6.

[0039] The lifting head 5 is equipped with a massage component, which is used to lift the head 5 to achieve massage; Among them, the top 5 can be in the form of a ball or a strip; like Figure 7As shown, the massage assembly includes a massage roller 15, which is rotatably disposed at the end of the lifting head 5 away from the second link 4; Thus, when the first drive member 9 and the second drive member 10 are activated, the first slider 6 and the second slider 7 are brought closer to each other, the first end and the second end are brought closer to each other, and the head 5 is lifted away from the back plate 1 to lift the face cover, thereby achieving massage. Optionally, such as Figure 11 As shown, the massage assembly includes a first air bag 16, and the end of the first air bag 16 near the back plate 1 is connected to the lifting head 5 via a telescopic elastomer 17. Therefore, when the lifting head 5 moves away from the back plate 1, it can drive the telescopic elastic body 17 and the first air bag 16 to move together. The lifting head 5 squeezes the telescopic elastic body 17, thereby the telescopic elastic body 17 pushes the first air bag 16 to lift the face cover, thus realizing the massage function. Optionally, such as Figure 12 As shown, the first air bag 16 is connected to the lifting head 5 at one end near the back plate 1. Thus, when the lifting head 5 moves away from the back plate 1, it pushes the first air bag 16, thereby lifting the face cover to achieve massage. Optionally, such as Figure 13 and Figure 14 As shown, the massage assembly includes a second air bag 18, and a channel is provided on the seat foam 14. The second air bag 18 is connected to the lifting head 5 at one end near the back panel 1. The second air bag 18 can be a Y-shaped structure, and the end that contacts the seat foam 14 has two contact ends. When the lifting head 5 moves away from the back plate 1, it can drive the second air bag 18 to move in the channel. After the two contact ends pass through the channel, they separate from each other and switch to the unfolded state, thereby lifting the face cover to achieve massage. When the lifting head 5 approaches the back plate 1 to achieve reset, it drives the second air bag 18 to move in the channel. The two contact ends approach each other to achieve contraction and switch to the retracted state to complete the hiding.

[0040] It should be noted that the seat foam 14 has an internal space for accommodating the mechanical sliding lifting massage device. A wear-resistant layer 22 is provided in the internal space. At the same time, when there is a channel on the seat foam 14, the inner wall of the channel is also provided with a wear-resistant layer 22 to prevent the seat foam 14 from being damaged. The wear-resistant layer 22 can be made of wear-resistant cloth and can be embedded in the seat foam 14 and integrally formed with the seat foam.

[0041] Working principle: When a person sits on a car seat and receives a massage, the first drive member 9 and the second drive member 10 are activated simultaneously. The drive end of the first drive member 9 rotates, the first part contracts, and the second part lengthens. The first slider 6 moves upward along the guide rod 8. At the same time, the drive end of the second drive member 10 rotates, winding up the second flexible traction member 13, which can drive the second slider 7 to move downward. This allows the first slider 6 and the second slider 7 to move closer to each other, the first end and the second end to move closer to each other, and the first hinge end and the second hinge end to rotate relative to each other, so that the lifting head 5 can move away from the back plate 1 and lift the face cover, thus realizing the massage. When the massage ends, the driving ends of the first driving member 9 and the second driving member 10 reverse, the first part lengthens and the second part contracts. At the same time, the driving end of the second driving member 10 unwinds the second flexible traction member 13, thereby moving the first slider 6 and the second slider 7 away from each other, and the first end and the second end away from each other. Meanwhile, under the pressure applied by the human body to the lifting head 5, the lifting head 5, the first slider 6 and the second slider 7 are reset.
