Description

Technical Field

[0001] This invention relates to the field of automotive seat technology, specifically to an automotive seat massage system with selectable massage levels. Background Technology

[0002] With the development of the automotive industry, people have increasingly higher requirements for the comfort of car seats, especially during long drives, where seat support and massage functions have become important needs for relieving fatigue. Currently, many high-end car seats on the market are equipped with massage functions.

[0003] An existing patent (authorization announcement number: CN221293150U) discloses a car seat massage mechanism. The key technical points of the solution are: when massage is needed, a second motor is activated, which drives the rotating shaft and the connected swing massage rod and massage ball to rotate. When the massage ball rotates, it intermittently passes through the slot to massage the user who is leaning against the seat back. When the massage position needs to be adjusted, a first motor is activated, which drives the first lead screw to rotate, thereby causing the slider and its motor fixing housing, second motor, rotating shaft, swing massage rod and massage ball to move closer or further apart. After the position is adjusted, the second motor is activated as before, and the rotation of the massage ball massages the user who is leaning against the seat back.

[0004] However, the above technical solution still has certain shortcomings. The seat massage system only provides a fixed intensity massage mode and cannot be personalized according to user needs, resulting in insufficient comfort. At the same time, different users have different pressure thresholds. Therefore, we propose a car seat massage system with selectable intensity levels. Summary of the Invention

[0018] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0019] In one embodiment, such as Figures 1-7 As shown, a car seat massage system with selectable intensity levels includes a seat cushion 1, a slide rail 2 at the bottom of the seat cushion 1, a backrest 4, a connector 3 for connecting the seat cushion 1 and the backrest 4, an adjustment rod 9 passing through the connector 3, a massage component 8 for massaging the back is provided inside the backrest 4, a mounting frame 5 is also provided inside the backrest 4, a drive component 6 for driving the position of the massage component 8 is mounted on the mounting frame 5, and an adjustment component 7 for adjusting the massage intensity is provided on the drive component 6. In this embodiment, by adjusting component 7, the user can select different massage levels, change the rotation speed and intensity of massage roller 83, and realize multi-level massage intensity adjustment. Drive component 6 can push massage component 8 to move along slide 85, so that massage roller 83 can accurately cover different areas of the user's back. Combined with adjustment rod 9, the angle of backrest 4 can be adjusted to further improve massage comfort.

[0020] In one embodiment, such as Figure 4 As shown, the massage component 8 includes a slide rail 85 fixedly opened on one side of the mounting bracket 5, a sliding block 84 sliding within the slide rail 85, a drive motor 81 fixedly installed on one side of the sliding block 84, a rotating rod 82 fixedly connected to the output end of the drive motor 81, and a massage roller 83 fixedly installed on the rotating rod 82. The massage roller 83 is provided with multiple sets of spherical particles, and the particles are made of nylon material. The drive motor 81 drives the rotating rod 82 to rotate, and the rotating rod 82 drives the massage roller 83 to rotate, so as to massage and roll the leather surface of the back of the chair 4. At the same time, a gear rack is provided on the other side of the rotating rod 82 to lock the position of the sliding block 84. The nylon material avoids scratching the seat fabric or the user's clothing. The particle arrangement can be optimized into a wave shape or matrix to enhance the massage coverage area and disperse pressure through multi-point contact.

[0021] In one embodiment, such as Figure 3 As shown, the drive assembly 6 includes an electric push rod 61 fixedly mounted on the other side of the mounting frame 5. The mounting frame 5 has two sets of fixing plates on its side, including a first fixing plate and a second fixing plate. A first rack 62 is slidably mounted on the first fixing plate, and a second rack 63 is fixedly mounted on the second fixing plate. The electric push rod 61 drives the first rack 62 to slide, forming a relative movement with the second fixed rack. In conjunction with the gears inside the adjusting assembly 7, the movement distance and position of the massage assembly 8 can be precisely controlled, ensuring that the massage roller 83 can cover different areas of the user's back. The slidable characteristic of the first rack 62 makes the movement of the massage assembly 8 more flexible and can be dynamically adjusted according to the user's body shape and usage needs. The two sets of fixing plates (the first fixing plate and the second fixing plate) provide a stable mounting base for the rack, ensuring that there will be no deviation or shaking during the transmission process, and improving the stability of the rack transmission.

[0022] In one embodiment, such as Figure 5 As shown, the adjusting rod 9 is fixedly installed at the bottom of the mounting frame 5 and is used to adjust the angle of the mounting frame 5. The angle of the mounting frame 5 can be changed by adjusting the adjusting rod 9, thereby adjusting the contact angle of the massage roller 83, so that the massage intensity and direction are more in line with the curve of the human back and improve comfort.

[0023] In one embodiment, such as Figure 6As shown, the adjusting assembly 7 includes a first gear 71, a second gear 72, and a third gear 73 inserted into the rotating rod 82, and an adjuster 75 for selectively engaging any gear with the rotating rod 82. The adjuster 75 is fixedly connected to the mounting plate 74. The number of teeth of the first gear 71, the second gear 72, and the third gear 73 decreases sequentially, and the module of the three sets of gears increases sequentially to maintain equal diameters. The first rack 62 and the second rack 63 can both mesh with any set of gears from the three sets. The first rack 62 is driven to move vertically by the electric push rod 61, from... The drive gear moves on the second rack 63, and three sets of equal diameter gears with increasing module (first / second / third gears 73) are used. The following are achieved by decreasing number of teeth: First gear 71 (low speed): large number of teeth provides high torque output to achieve deep muscle massage; Third gear 73 (high speed): small number of teeth achieves rapid vibration, suitable for superficial muscle relaxation; Second gear 72 (medium speed): balances speed and force. By gradually increasing the module, the outer diameter of the gears is kept consistent, ensuring that the meshing position of the rack is fixed in all gears, avoiding the defect of traditional transmission mechanisms that require adjustment of the meshing position.

[0024] In one embodiment, such as Figure 7 As shown, the regulator 75 consists of a limiting rod 751, a sliding column 752, a spring 753, a first locking block 754, a second locking block 755, and a rotating shaft 756. Two sets of limiting rods 751 are provided, with one end of each rod fixedly connected to one side of the mounting plate 74. A first gear 71, a second gear 72, and a third gear 73 are fixedly passed through the limiting rod 751. The middle section of the long side of the mounting plate 74 is rotatably connected to the sliding column 752. The middle of the sliding column 752 is hollow, and a spring 753 is fixedly installed at the center of the inner circle of the sliding column 752. A first locking block 754 is fixedly installed on one side of the inner wall of the sliding column 752. Multiple sets of sliding columns 752 are provided, with a second locking block 755 on the outer wall of the second set of sliding columns 752 to engage the first locking block 754. The outer walls of the three sets of sliding columns 752 are also equipped with locking blocks that engage the second set of sliding columns 752. The diameters of the three sets of sliding columns 752 decrease in that order. The first locking block 754 and the second locking block 755 are both made of elastic material. By pressing the mounting plate 74, the sliding columns 752 move parallel to each other and press the spring 753. When the spring 753 is compressed to its limit, the first locking block 754 on the inner wall of the sliding column 752 passes through the second locking block 755, and the second locking block 755 engages with the first locking block 754. Similarly, by continuing to press the mounting plate 74, the second set of sliding columns 752 engages with the third set of sliding columns 752, providing the user with a precise operating feel and facilitating the adjustment of different massage levels. Conversely, when it is necessary to increase the massage intensity, simply pull the mounting plate 74 to complete the corresponding operation. As a supplement: when the rotating rod 82 rotates, the gear and the mounting plate 74 will rotate synchronously with the rotating rod 82 to prevent motion interference. At the same time, the connection between the sliding column 752, the mounting plate 74 and the rotating rod 82 are all rotational connections, which will not interfere with the locking between the blocks. The rotating rod 82 will not drive the sliding column 752 to rotate, but only drives the mounting plate 74 to rotate through the limit rod 751.

[0025] The above embodiment discloses a car seat massage system with selectable massage levels. In this system, the massage roller 83 is rotated by the drive motor 81 in the massage assembly 8 to massage the user. At the same time, the electric push rod 61 in the drive assembly 6 drives the vertical movement of the first rack 62, which in turn helps the gear move up and down on the second rack 63. This allows for adjustment of the position of the rotating rod 82 to massage the user's back area. Furthermore, the position of the three sets of gears can be changed by adjusting the number of teeth on the three sets of gears. By changing the number of gear rotations when the first rack 62 moves, the intensity of the massage can be adjusted, thus achieving adjustable massage levels.

[0026] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
