[0012] In order to make the purpose, technical scheme and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0013] Combination Figure 1-2 The embodiment of the present invention provides a massage chair, comprising a chair frame 1, a base 2, an armrest 4 and a driving assembly 5, wherein the armrest 4 is rotatably or slidably arranged on both sides of the chair frame 1 or the base 2; the armrest 4 is provided with a receiving groove 41 for accommodating the user's arm;

[0014] The driving assembly 5 drives the armrest 4 to swing or slide relative to the chair frame 1 to drive the user's arm to move relative to the user's body.

[0015] That is, the massage chair provided by the embodiment of the present invention has a drive assembly and an armrest on the chair frame, and the drive assembly can drive the armrest to move relative to the chair frame, thereby increasing the function of adjusting the angle of the massage chair armrest. When the chair frame is in a sitting position or a reclining position, the back and / or arms of the user can be stretched and massaged, and the shoulder joints of the user can also be lifted to massage and relax the shoulder joints. In addition, when the armrest is raised to the highest position, there is enough space to allow the user to sit in the massage chair from the side, which is convenient for the user to use, thereby improving the massage experience.

[0016] Further, in one example, Figure 1As shown, a clamping member 412 is provided in the accommodation groove 41. The clamping member 412 is used to clamp the arm or palm located in the accommodation groove 41, so that the arm follows the movement of the armrest.

[0017] Specifically, the clamping member 41 can be a massage airbag. When the massage airbag is inflated, it can squeeze and hold the user's arm or palm, so that the arm follows the movement of the armrest, and at the same time, it can also massage the user's arm or palm.

[0018] Furthermore, in one example, as Figure 2 shown, the armrest is rotatably arranged on the chair frame. The massage chair further includes a main shaft 6 and a limit post 7. The main shaft 6 and the limit post 7 are fixed on the chair frame 1. Limit sliding grooves 42 are provided on the armrest 4. The armrest 4 is fixed on the main shaft 6. The limit post 7 is arranged in the limit sliding groove 42 to limit the swinging range of the armrest 4. The driving assembly 5 is arranged on the armrest 4. The driving assembly 5 drives the armrest 4 to swing up and down with the main shaft 6 as the center and within the movement track of the limit post 7 in the limit sliding groove 42, so as to stretch and massage the user's back and / or arm.

[0019] Specifically, the main shaft 6 is connected to the armrest 4 through a main shaft bearing 61 and a main shaft bearing sleeve 62. The armrest 4 can include a left armrest and a right armrest. The driving assembly 5 can include a left driving assembly and a right driving assembly. The left driving assembly drives the left armrest to swing, and the right driving assembly drives the right armrest to swing. In this way, the driving assembly 5 can drive the left armrest and the right armrest to swing simultaneously, with the same frequency and the same angle, or can independently control the left armrest and the right armrest respectively, and set different angle swings according to the user's needs. For example, when the left armrest is lifted to the highest position, the right armrest can be lowered to the lowest position to stretch the various muscles of the user's back and arm. In addition, according to the user's sitting habit, when the user is about to use, the left armrest or the right armrest can be controlled to lift to the highest position to facilitate the user to sit into the massage chair, thereby improving the user experience.

[0020] Furthermore, in one example, as Figure 2 shown, the driving assembly 5 includes a sector gear 51, a motor 52 and a pinion gear 53. The handle part of the sector gear 51 is connected to the main shaft 6. The limit post 7 is connected to the middle part of the sector gear 51. The pinion gear 53 is fixed on the armrest 4 through a transmission shaft 54 and meshes with the end of the sector gear 51 far from the ground. The motor 52 is fixed on the armrest 4 and drives the pinion gear 53 to rotate so that the pinion gear 53 travels on the sector gear 51, pushing the armrest 4 to move up or down with the main shaft 6 as the center.

[0021] Specifically, the transmission shaft 54 is fixed to the armrest 4 through a transmission bearing 541 and a transmission bearing sleeve 542. The pinion 53 is fixed to the transmission shaft 54. The massage chair is placed on the ground. In the initial state, the armrest 4 is arranged parallel to the ground. At this time, the limit post 7 is located at the bottommost end of the limit chute 42. As shown in the figure, the handle part of the sector gear 51 is connected to the main shaft 6, the middle part is connected to the limit post 7, and the upper part meshes with the pinion 53. The motor 52 is fixed on the armrest 4 and is located beside the transmission shaft 54. When the motor 52 rotates forward, it drives the transmission shaft 54 to rotate through transmission gears and the like, and then drives the pinion 53 to rotate, so that the pinion 53 moves downward on the sector gear 51 from top to bottom, thereby pushing the armrest 4 to rise from the horizontal position with the main shaft 6 as the center until it rises to the highest position. At this time, the limit post 7 slides from the lowermost end of the limit chute 42 to the uppermost end of the limit chute 42; when the motor 52 rotates in reverse, it drives the transmission shaft 54 to rotate through transmission gears and the like, and then drives the pinion 53 to rotate, so that the pinion 53 moves upward on the sector gear 51 from bottom to top, thereby pushing the armrest 4 to descend from the horizontal position with the main shaft 6 as the center until it descends to the initial horizontal position. At this time, the limit post 7 slides from the uppermost end of the limit chute 42 to the lowermost end of the limit chute 42; thus, one cycle of the swing arm is completed. Of course, the left armrest and the right armrest can rise or fall simultaneously, or one can rise while the other falls, just by setting the motor 52 to rotate in different directions.

[0022] Further, in one example, the sector gear 51 has a D-shaped inner hole for fixing to the main shaft 6 and the limit post 7.

[0023] Further, in one example, as Figure 2 shown, it further includes a Hall sensor board 8 and magnetic beads (not shown in the figure). The Hall sensor board 8 is arranged on the armrest, and the magnetic beads are arranged on both sides of the sector gear 51.

[0024] Adopting the meshing mode of the sector gear and the pinion to drive the swing of the armrest can accurately control the swing angle of the armrest, and the structure is relatively simple, easy to implement, and the cost is also relatively low.

[0025] Specifically, through the detection by the Hall sensor board and the magnetic beads, the movement angle between the sector gear and the pinion can be designed to be at most 90 degrees, so that there is enough space for yielding, allowing the user to sit into the massage chair from the side. The driving of the arms is designed with independent motors on both sides. Under the action arrangement of the massage program, actions such as the alternate lifting or simultaneous lifting of the two arms can be realized, achieving the massage and relaxation effect on the arms and shoulders.

[0026] Further, in one example, as Figure 2As shown, an armrest fixing member 43 is provided on the chair frame, and the main shaft 6 and the limit post 7 are arranged on the armrest fixing member 43 so that the main shaft 6 and the limit post 7 are in the same plane, enabling the armrest 4 to swing smoothly. In this way, in the positioning of the arm rotation axis, it can be as close as possible to the position of the human shoulder joint, reducing the relative movement between the user's arm and the armrest body, thereby enhancing the massage experience.

[0027] Further, in one example, as Figure 2 shown, it further includes a main shaft fixing member 63. The main shaft fixing member 63 is U-shaped. The two ends of the main shaft fixing member 63 are arranged on the armrest 4, and the middle end is connected to the main shaft 6 and is located outside the sector gear 51 to enhance the strength of the main shaft 6.

[0028] Specifically, the middle end of the main shaft fixing member 63 is connected to the main shaft through a bushing 10. Since the armrest is provided with components such as massage airbags and drive components, including the armrest housing, etc., it results in a relatively heavy weight. If only the main shaft rotates, the main shaft is subjected to more force, is easily damaged, and makes the swing of the armrest unstable. Adding the main shaft fixing member can strengthen the main shaft, increase stability, and prevent the main shaft from being damaged.

[0029] Further, in one example, as Figure 2 shown, it further includes a transmission shaft fixing member 543. The transmission shaft fixing member 543 is U-shaped. The two ends of the transmission shaft fixing member 543 are fixed on the armrest 4, and the middle end is connected to the transmission shaft 54 and is located outside the motor 52 to enhance the strength of the transmission shaft 54.

[0030] Similarly, adding the transmission shaft fixing member can prevent the transmission shaft from being subjected to more force, strengthen the transmission shaft, increase the stability of the driving force, and prevent the transmission shaft from being damaged.

[0031] Further, in one example, as Figure 1 and 2 shown, a pinch prevention sensor 45 is provided at the bottom or top of the armrest 4.

[0032] The pinch prevention sensor can be an infrared sensor, a laser sensor, a capacitive or electromagnetic sensor. Of course, in order to improve the detection accuracy, it can also be a combination of multiple sensors. The provision of the pinch prevention sensor can prevent the human body or animals from being pinched by the swinging armrest during the use of the massage chair, improving the safety of using the massage chair. It can also prevent foreign objects from being stuck under or above the armrest during the use of the massage chair and damaging the armrest of the massage chair.

[0033] Furthermore, in one example, the massage chair also includes a center plate (not shown in the figure), which is connected to the drive assembly to control the up and down swinging of the armrest; connected to the Hall sensor to control the swing angle of the armrest; connected to the anti-pinch sensor to prevent the armrest from swinging and clamping foreign objects; and connected to the clamping member to control the arm to follow the swing of the armrest.

[0034] 另外,该容纳槽41可以是半包围状,以免在夹持件,例如按摩气囊不充气时手臂脱出,影响摆臂效果。 In addition, after the massage airbag is inflated, the human arm can be fixed, and the waist muscles and arm muscles of the dorsal side of the human body are stretched. The larger the angle of the swing arm, the more obvious the stretching effect. When the massage airbag is deflated, the handrail swings up and down, and only the human arm swings the arm to relax the human arms, shoulders and other parts.

[0035] Further, in another example, the chair frame is rotatably arranged on the base, further comprising a push rod, one end of the push rod is hinged with the base, and the other end is hinged with the chair frame, the push rod drives the chair frame to rotate relative to the base, the armrest is slidably arranged on the side of the base, and the driving assembly drives the armrest to slide relative to the base.这样使用者手臂可相对使用者臀部前后滑动进行拉伸。

[0036] Furthermore, in one example, a main control board is also included, and the main control board is electrically connected to the push rod and the driving assembly respectively to control the synchronous movement of the push rod and the driving assembly.

[0037] Specifically, in one example, the drive assembly drives the user's arm to move toward the user's rear side, and the push rod pushes the chair frame to move toward the user's front side, thereby stretching the user's arm relative to the user's body.

[0038] The massage chair provided by the embodiment of the present invention provides a driving component and a handrail on the chair frame, which can drive the armrests to move relative to the chair frame, and adds the armrest angle adjustment function of the massage chair. In the seating position or backward state, the back and / or arm of the user can be stretched and massaged, and at the same time, the shoulder joints of the user can be lifted and massaged and relaxed.另外,扶手抬起至最高也可以有足够的空间让位,让使用者能够从侧面坐入按摩椅,方便使用者使用,从而提高按摩体验。

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications falling within the scope of the present application.

[0040] Obviously, those skilled in the art can make various changes and modifications to this application without departing from the spirit and scope of this application. Thus, if these modifications and variations of this application fall within the scope of the claims of this application and their equivalent technologies, this application is also intended to cover these changes and modifications.
