[0019] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0020] It should be noted that the terms "comprising" and "having" and any variations thereof in the specification, claims and accompanying drawings of this utility model are intended to cover non-exclusive inclusion. For example, a process, method, apparatus, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such processes, methods, products or devices.

[0021] The following is in conjunction with the appendix Figures 1-8 This application will be described in further detail.

[0022] Example 1, Reference Figures 1-3 The back massager mechanism shown includes: a frame 1, a massage mechanism 2, a guide rail 3, a cable 4, and a traction mechanism 5, wherein the guide rail 3 is disposed on the frame 1; The massage mechanism 2 includes a gearbox 21, a massage head 22, and a drive assembly. The gearbox 21 is slidably mounted on the guide rail 3, the massage head 22 is mounted on the gearbox 21, and the drive assembly is used to drive the gearbox 21 to slide on the guide rail 3. The gearbox 21 is equipped with a battery compartment with a built-in power supply to power the gearbox. The built-in power supply powers the gearbox 21 through a built-in battery cell. The battery compartment is integrated with the massage mechanism, but it can also be designed as an independent fixed form as needed. The two ends of the cable 4 are a fixed end and a moving end, respectively. The moving end is connected to the gearbox 21, and the fixed end is set on the frame 1 (connected to the external control and charging ports). The traction mechanism 5 is used to pull the cable 4, so that the moving end moves synchronously with the gearbox 21.

[0023] Based on the above structure, when the user leans against the mechanism, the guide rail 3 extends from bottom to top. The gearbox 21 is driven by the drive assembly to slide on the guide rail 3, causing the massage head 22 to move up and down on the user's back, thereby massaging different parts of the user's back and providing a better user experience. Since the gearbox 21 reciprocates during the massage, the cable 4 used for transmitting signals and conducting electricity needs to move synchronously with the gearbox 21. Therefore, a traction mechanism 5 is provided to pull the cable 4, so that the moving end moves synchronously with the gearbox 21, thereby reducing damage to the cable 4 during the activity and improving the smoothness of the cable 4's movement during the movement of the gearbox 21.

[0024] like Figure 2 and Figure 3 As shown, the drive assembly includes a motor 23, a gear set 24, a first gear 25, and a second gear 26. The motor 23, gear set 24, and first gear 25 are all mounted on the gearbox 21, and the massage head 22 is mounted on the second gear 26. The motor 23 drives the first gear 25 and the second gear 26 to rotate through the gear set 24. A rack 31 is provided on one side of the guide rail 3, and the first gear 25 meshes with the rack 31. In this way, the motor 23 provides power, and the gear set 24 transmits the power of the motor 23, causing the first gear 25 and the second gear 26 to rotate, thereby driving the gearbox 21 to slide on the guide rail 3, and causing the massage head 21 to move.

[0025] Further optimizations include, for example Figure 1 and Figure 2 As shown, the guide rail 3 can be a flexible guide rail or a rigid guide rail. There are two guide rails 3. There are also two massage heads 22, two gear sets 24, two first gears 25 and two second gears 26. The motor 23 drives the two first gears 25 and the two second gears 26 to rotate through the two gear sets 24 respectively. The two first gears 25 mesh with the two racks 31 respectively, so that the gearbox 21 slides more stably and drives the two massage heads 22 to massage the user's back, improving the user's experience.

[0026] like Figure 4 As shown, reinforcing ribs 32 are provided on both sides of the guide rail 3. The specific structure of the reinforcing ribs 32 can be a diagonally intersecting rib structure (several V-shaped ribs connected in sequence). This method can effectively improve the overall rigidity of the guide rail 3, allowing the guide rail 3 to maintain good rigidity while using less material; in addition to the above-mentioned guide rail 3 structure, such as Figure 5As shown, the cross-section of the guide rail 3 in the sliding direction of the gearbox 21 is U-shaped. In other words, the guide rail 3 can also be set as a hollow structure, which can achieve the same effect.

[0027] like Figure 1 As shown, a first cable rack 11 is provided on one side of the frame 1. The extension direction of the first cable rack 11 is consistent with the extension direction of the guide rail 3. The cable 4 is passed through the first cable rack 11 to prevent the cable 4 from being directly exposed to the outside, thus protecting the cable 4.

[0028] like Figure 1 and Figure 2 As shown, the traction mechanism 5 includes a first fixed pulley 52, a second fixed pulley 53, a first movable pulley 54, and a first traction rope 55 (which can be a nylon rope, etc.). The first fixed pulley 52, the second fixed pulley 53, the first movable pulley 54, and the first traction rope 55 are all disposed within the first cable frame 11. The first fixed pulley 52 and the second fixed pulley 53 are respectively disposed at both ends of the first cable frame 11. The first traction rope 55 is wound around the first fixed pulley 52 and the second fixed pulley 53, and one end of the first traction rope 55 is connected to the gearbox. 21 is connected to the first movable pulley 54 at one end and the other end is connected to the first movable pulley 54. The cable 4 is wound around the first movable pulley 54 (the fixed end of the cable 4 is close to the side of the second fixed pulley 53, that is, the cable 4 is in an inverted U shape). The first movable pulley 54 is set between the first fixed pulley 52 and the second fixed pulley 53. In this way, when the gearbox 21 slides on the guide rail 3, it drags the first traction rope 55, so that the first movable pulley 54 and the gearbox 21 move synchronously in the same direction, thereby pulling the cable 4 and making the cable 4 move adaptively.

[0029] This application also includes Embodiment Two, which differs from Embodiment One in that, as Figure 6 As shown, the traction mechanism 5 includes a cable chain 51, which is disposed inside the first cable frame 11. The cable 4 is arranged on the cable chain 51, and the two ends of the cable chain 51 are connected to the gearbox 21 and the first cable frame 11 respectively. In this way, by placing the cable 4 on the cable chain 51, the cable 4 is dragged and protected by the synchronous movement of the cable chain 51 and the cable 4.

[0030] This application also includes Embodiment Three, which differs from Embodiment One in that, as Figure 7 and Figure 8As shown, a second cable rack 12 is provided on one side of the frame 1, and a third cable rack 13 is provided at the bottom of the frame 1. The extension direction of the second cable rack 12 is consistent with the extension direction of the guide rail 3, and the extension direction of the third cable rack 13 is perpendicular to the extension direction of the guide rail 3. The traction mechanism 5 includes a third fixed pulley 56, a fourth fixed pulley 57, a second movable pulley 58, a second traction rope 59 (which can be a nylon rope, etc.), and an elastic element 6. The third fixed pulley 56 and the fourth fixed pulley 57 are respectively located at both ends of the third cable rack 13, and the second movable pulley 58 is respectively located between the third fixed pulley 56 and the fourth fixed pulley 57. The cable 4 is wound around the third fixed pulley 56 and the second movable pulley 58 (the moving end and the fixed end of the cable 4 are located on the side closer to the third fixed pulley 56). The elastic element 6 is located inside the second cable rack 12 (the elastic element 6 can be a nylon rope, etc.). The system consists of springs, etc. One end of the elastic element 6 is connected to the frame 1, and the other end is connected to the second traction rope 59 (the elastic element 6 performs its elastic work in the vertical direction). One end of the second traction rope 59 is connected to the elastic element 6, and the other end is connected to the second movable pulley 58. The second traction rope 59 is wound around the fourth fixed pulley 57 (the fourth fixed pulley 57 is located at the end of the third cable frame 13 near the second cable frame 12). Thus, when the gearbox 21 moves upward, it drags the cable 4. At this time, the second traction rope 59 drags the elastic element 6, causing the elastic element 6 to be stretched. At this time, the second movable pulley 58 moves to the side of the third fixed pulley 56, thereby making the cable 4 adapt to the movement of the gearbox 21. When the gearbox 21 moves downward, the elastic element 6 contracts, pulling the second traction rope 59, causing the second movable pulley 58 to move to the side of the fourth fixed pulley 57.

[0031] Further optimization is that the frame 1 and guide rail 3 in this application can both be made of flexible plastic, so that this application can be deformed to a certain extent according to the actual use scenario, the massage head 22 always conforms to the curve of the human body, and the rack is fixed in the horizontal direction relative to the first gear 25 through the guide rail groove inside the gearbox.

[0032] The above are merely preferred embodiments of this application, and the present invention is not limited to the above embodiments. It is understood that other improvements and variations that can be directly derived or conceived by those skilled in the art without departing from the spirit and concept of the present invention should be considered to be included within the protection scope of the present invention.
