Massage chairs are equipped with a variety of massage techniques, such as kneading, pushing, acupressure, and tapping, which can provide comprehensive massage for various parts of the body, including the neck, shoulders, back, waist, hips, legs, and feet. Through precise program settings, they can simulate the techniques of professional massage therapists, deeply relieve muscle tension, promote blood circulation, and effectively eliminate physical fatigue.
[0003] When using existing massage chairs, the user is placed in the recess of the chair. However, the overall tilt angle of the massage chair is always fixed, which cannot meet the user's desire for a larger reclining angle for rest, thus reducing the overall practicality. Utility Model Content
[0004] The purpose of this invention is to provide a massage chair that is easy to adjust in angle, in order to solve the problem mentioned in the background art that the overall tilt angle of the massage chair is always fixed, which cannot meet the purpose of people wanting to lie flat at a larger angle for rest, thus reducing the overall practicality.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a massage chair with adjustable angle, comprising a massage chair body, on both sides of which are provided with supporting base plates. A supporting side plate is fixedly connected to the upper surface of the supporting base plate. A first mounting groove is formed inside the supporting side plate, and a second mounting groove is formed above the first mounting groove. An adjusting worm gear is installed on the inner wall of the second mounting groove. A drive motor is fixedly connected to the bottom surface of the first mounting groove, and a first gear is fixedly connected to the output end of the drive motor. A transmission worm is connected to the inner wall of the massage chair body, and a second gear is fixedly connected to the shaft of the transmission worm facing the drive motor. A limiting compression block is fixedly connected to the lower side surface of the adjusting worm gear. A third mounting groove is formed on the lower side surface of the second mounting groove, and a limiting braking mechanism is provided on the inner wall of the third mounting groove. The limiting compression block pushes a linkage slider, which in turn drives a first piston column to move, causing airflow and subsequently pushing a second piston column and a friction brake block to slide against a brake cylinder.
[0006] Preferably, the second mounting groove is cylindrical, the adjusting worm gear is rotatably connected to the second mounting groove, and one end of the adjusting worm gear's shaft passes through the inner wall of the second mounting groove. The adjusting worm gear's shaft is fixedly connected to the side surface of the massage chair body.
[0007] By adopting the above technical solution, the cylindrical design of the second mounting groove can provide a stable and smooth rotation space for the adjusting worm gear, reduce friction and shaking during rotation, and ensure the accuracy and stability of the adjusting worm gear rotation.
[0008] Preferably, the adjusting worm gear has a missing tooth design, the first gear and the second gear are meshed, the transmission worm is rotatably connected to the massage chair body, and the transmission worm is meshed with the adjusting worm gear.
[0009] With the above technical solution, the transmission worm gear is rotatably connected to the massage chair body and meshes with the adjusting worm wheel, so that the power of the drive motor can be transmitted to the adjusting worm wheel through the transmission worm gear, thereby driving the massage chair body to rotate and realize the angle adjustment function.
[0010] Preferably, the limiting braking mechanism includes a linkage slider, which is disposed on the inner wall of the upper cavity of the third mounting groove. A first piston is fixedly connected to one end of the linkage slider, a second piston is connected to the inner wall of the lower cavity of the third mounting groove, a friction brake block is fixedly connected to the lower end of the second piston, and a brake cylinder is fixedly connected to one end of the shaft of the transmission worm.
[0011] By adopting the above technical solution, a relatively flexible and reliable braking function is achieved through the cooperation of the linkage slider, the first piston rod, the second piston rod, the friction brake block and the brake cylinder. The structural design is reasonable and compact.
[0012] Preferably, the linkage slider and the third mounting groove are slidably connected, and a spring is connected between the linkage slider and the third mounting groove. The linkage slider is L-shaped, and the lower surface of the linkage slider facing the limiting extrusion block is arc-shaped.
[0013] By adopting the above technical solution, the linkage slider is slidably connected to the third mounting groove and connected by a spring, so that the linkage slider can slide flexibly when subjected to external force and can be reset under the action of the spring after the external force disappears, thus ensuring the repeatability and stability of the braking mechanism.
[0014] Preferably, the piston heads of the first piston rod and the second piston rod are both in contact with the inner wall of the third mounting groove, the second piston rod and the third mounting groove are slidably connected, and a spring is connected between the second piston rod and the third mounting groove.
[0015] By adopting the above technical solution, the piston heads of the first and second piston columns are in close contact with the inner wall of the third mounting groove, which can ensure the sealing when air flows in the third mounting groove and improve the efficiency of driving the component to move through air flow.
[0016] Preferably, a friction pad is provided on the outer surface of one end of the brake cylinder, the friction pad of the brake cylinder is located below the friction brake block, and a strip groove is provided on the lower surface of the friction brake block.
[0017] By adopting the above technical solution, the friction pads on the brake cylinder can increase the friction between them and the friction brake block, making the braking effect more reliable, effectively preventing the transmission worm gear from rotating, and thus fixing the angle of the massage chair.
[0018] Compared with the prior art, the beneficial effects of this utility model are: this massage chair is easy to adjust in angle.
[0019] 1. The drive motor drives the first gear to rotate, and the first gear meshes with the second gear, which in turn causes the transmission worm to rotate. The transmission worm meshes with the toothed adjustment worm wheel, which can realize multi-angle adjustment of the massage chair body. The toothed design can precisely control the adjustment angle, avoid over-adjustment, meet the user's needs for different reclining angles, improve the comfort and functionality of use, and solve the problem of fixed angle in traditional massage chairs.
[0020] 2. When the worm gear rotates, the limiting and squeezing block at its lower end pushes the linkage slider, which in turn drives the first piston column to move. This causes airflow to push the second piston column and the friction brake block to slide against the brake cylinder to achieve braking. The brake cylinder has friction plates and the friction brake block has grooves, which increases the friction force and ensures that the massage chair can be stably fixed after being adjusted to a suitable angle. This prevents the angle from changing due to external forces or its own weight, thus ensuring the safety of the user.
[0021] 3. The second mounting groove is cylindrical, providing stable rotation space for adjusting the worm gear. The linkage slider is slidably connected to the third mounting groove and reset by a spring. The first and second piston columns fit against the inner wall of the third mounting groove to ensure sealing. These designs ensure smooth angle adjustment and braking processes, and improve the stability and durability of the device. Attached Figure Description

[0029] The technical solutions of the present utility model 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 utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0030] Please see Figure 1-6 This utility model provides a technical solution: a massage chair with easy angle adjustment, including a massage chair body 1, a supporting base plate 2, supporting side plates 3, a first mounting groove 4, a second mounting groove 5, an adjusting worm gear 6, a drive motor 7, a first gear 8, a transmission worm 9, a second gear 10, a limiting compression block 11, a third mounting groove 12, a linkage slider 13, a first piston column 14, a second piston column 15, a friction brake block 16, and a brake cylinder 17. The massage chair body 1 has supporting base plates 2 on both sides, and the upper surface of the supporting base plates 2 is fixedly connected to the supporting side plates. Plate 3 and the second mounting groove 5 are cylindrical in design. The adjusting worm gear 6 is rotatably connected to the second mounting groove 5, and one end of the rotating shaft of the adjusting worm gear 6 passes through the inner wall of the second mounting groove 5. The rotating shaft of the adjusting worm gear 6 is fixedly connected to the side surface of the massage chair body 1. When the drive motor 7 is turned on, the first gear 8 at its output end rotates and meshes with the second gear 10, driving the transmission worm 9 to rotate. The transmission worm 9 meshes with the adjusting worm gear 6. The rotating shaft of the adjusting worm gear 6 is fixedly connected to the side surface of the massage chair body 1, which facilitates the rotation of the massage chair body 1 when the adjusting worm gear 6 rotates, thereby realizing angle adjustment.
[0031] The support side plate 3 has a first mounting groove 4 inside, and a second mounting groove 5 is provided above the first mounting groove 4. An adjusting worm gear 6 is installed on the inner wall of the second mounting groove 5. A drive motor 7 is fixedly connected to the bottom surface of the first mounting groove 4. A first gear 8 is fixedly connected to the output end of the drive motor 7. A transmission worm 9 is connected to the inner wall of the massage chair body 1. A second gear 10 is fixedly connected to the shaft of the transmission worm 9 facing the drive motor 7. The adjusting worm gear 6 has a missing tooth design. The first gear 8 and the second gear 10 are meshed. The transmission worm 9 is rotatably connected to the massage chair body 1, and the transmission worm 9 is meshed with the adjusting worm gear 6. When the massage chair is adjusted, the limiting squeezing block 11 at the lower end of the adjusting worm gear 6 rotates accordingly. When the adjustment reaches the limiting angle, the limiting squeezing block 11 first pushes the arc-shaped surface of the linkage slider 13 in the third mounting groove 12, so that the linkage slider 13 drives the first piston column 14 to move. Finally, the limiting squeezing block 11 is stuck on the L-shaped surface of the linkage slider 13 for limiting.
[0032] A limiting compression block 11 is fixedly connected to the lower end side surface of the adjusting worm gear 6. A third mounting groove 12 is opened on the lower end side surface of the second mounting groove 5. The limiting braking mechanism includes a linkage slider 13, which is disposed on the inner wall of the upper cavity of the third mounting groove 12. A first piston rod 14 is fixedly connected to one end of the linkage slider 13. A second piston rod 15 is connected to the inner wall of the lower cavity of the third mounting groove 12. A friction brake block 16 is fixedly connected to the lower end of the second piston rod 15. A brake cylinder 17 is fixedly connected to one end of the rotating shaft of the transmission worm gear 9. The movable slider 13 and the third mounting groove 12 form a sliding connection, and a spring is connected between the linkage slider 13 and the third mounting groove 12. The linkage slider 13 has an L-shaped design, and the lower surface of the linkage slider 13 facing the limiting extrusion block 11 has an arc-shaped design. The piston head of the first piston column 14 is in contact with the inner wall of the third mounting groove 12. The first piston column 14 pushes the air to flow, so that the air pushes the second piston column 15 down. The friction brake block 16 at the lower end of the second piston column 15 slides down and abuts against the brake cylinder 17 at one end of the transmission worm gear 9 shaft.
[0033] The inner wall of the third mounting groove 12 is provided with a limit braking mechanism. The limit squeezing block 11 pushes the linkage slider 13, which in turn drives the first piston column 14 to move, causing air flow and pushing the second piston column 15 and the friction brake block 16 to slide against the brake cylinder 17. The piston heads of the first piston column 14 and the second piston column 15 are both in contact with the inner wall of the third mounting groove 12. The second piston column 15 and the third mounting groove 12 are slidably connected, and a spring is connected between the second piston column 15 and the third mounting groove 12. A friction plate is provided on the outer surface of one end of the brake cylinder 17. The friction plate of the brake cylinder 17 is located below the friction brake block 16. A strip groove is provided on the lower surface of the friction brake block 16. The friction plate on the outer surface of the brake cylinder 17 and the strip groove on the lower surface of the friction brake block 16 increase the friction force, preventing the transmission worm gear 9 from rotating, fixing the angle of the massage chair to prevent excessive rotation, and protecting the moving parts of the device.
[0034] Working principle: When using this massage chair with easy angle adjustment, the drive motor 7 drives the first gear 8 to rotate. The first gear 8 drives the second gear 10 and the transmission worm gear 9 to rotate. The transmission worm gear 9 meshes with the adjusting worm wheel 6, thereby driving the massage chair body 1 to change the angle. When the adjusting worm wheel 6 rotates to the limit angle, the limiting squeeze block 11 at its lower end pushes the linkage slider 13. After being pushed, it drives the first piston column 14 to slide in the third mounting groove 12. The flowing air pushes the second piston column 15 down. The friction brake block 16 at the lower end of the second piston column 15 slides down and abuts against the brake cylinder 17 to prevent the transmission worm gear 9 from rotating, which increases the overall practicality.
[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
