DETAILED DESCRIPTION
[0038] Embodiment 1
[0039] A protective device for a dual-movement massage chair is provided in this embodiment. Figure 1-8As shown, it is particularly suitable for structures with large curvature of the guide rail, such as Figure 1 As shown, it includes a first massage movement 10 and a second massage movement 20, the first massage movement 10 and the second massage movement 20 are slidably adapted to the guide rail, at least one of the first massage movement 10 and the second massage movement 20 is installed with a first anti-collision device 30, the first anti-collision device 30 includes a first mounting seat 301, the first mounting seat 301 is pivotally connected with a swingable first anti-collision block 302, and an elastic member 303 is provided between the first anti-collision block 302 and the first mounting seat 301, so that before the first massage movement 10 and the second massage movement 20 collide, the first anti-collision block 302 abuts against the first massage movement 10 or the second massage movement 20. Among them, the role of the elastic member 303 is to prevent the first anti-collision block 302 from swinging unpredictably and irregularly due to the non-uniform speed of the massage movement.
[0040] Therefore, when the massage movement moves on the guide rail, the first anti-collision block 302 automatically adjusts the swing angle to adapt to the collision angle between the first massage movement 10 and the second massage movement 20, so that when the first massage movement 10 and the second massage movement 20 collide, the first anti-collision block 302 can absorb the collision force to avoid direct collision between the first massage movement 10 and the second massage movement 20, thereby extending the service life of the first massage movement 10 and the second massage movement 20.
[0041] In this embodiment, Figure 3 As shown, an upper limit portion 3011 is provided at the upper portion of the first mounting seat 301, and a lower limit portion 3012 is provided at the lower portion of the first mounting seat 301 to prevent the first anti-collision block 302 from swinging upward or downward excessively, thereby avoiding a direct collision between the first massage movement 10 and the second massage movement 20 caused by the first anti-collision block 302 being out of the working position.
[0042] In this embodiment, a first fixing hole 304 is provided at the bottom of the first mounting seat 301, a second fixing hole 305 is provided at the bottom of the first anti-collision block 302, and two ends of the elastic member 303 are respectively connected to the first fixing hole 304 and the second fixing hole 305. Further, a first fixing column is provided at the bottom of the first mounting seat 301, the first fixing column is provided with a first fixing hole 304, the bottom of the first anti-collision block 302 is provided with a second fixing column, and the second fixing column is provided with a second fixing hole 305. The elastic member 303 is a tension spring with hooks at both ends, and the hooks at both ends are fixedly connected to the first fixing hole 304 and the second fixing hole 305, respectively.
[0043] In this embodiment, the first mounting seat 301 is provided with a pivot hole, and the first anti-collision block 302 is provided with a connecting hole adapted to the pivot hole. A pin shaft 306 is passed through the pivot hole and the connecting hole. The first anti-collision block 302 rotates around the pin shaft 306. An anti-detachment pin 307 is inserted at the end of the pin shaft 306 to prevent the first anti-collision block 302 from detaching from the first mounting seat 301 due to the detachment of the pin shaft 306 during the swinging process of the first anti-collision block 302, thereby ensuring the stable operation of the first anti-collision block 302.
[0044] In this embodiment, one of the first massage movement 10 and the second massage movement 20 is installed with a first anti-collision device 30, and the other is installed with a second anti-collision device 40, and the second anti-collision device 40 includes a second mounting seat 401, and the second mounting seat 401 is provided with a second anti-collision block 402, so that before the first massage movement 10 and the second massage movement 20 collide, the second anti-collision block 402 and the first anti-collision block 302 abut and collide with each other. Specifically, the first massage movement 10 is located above the second massage movement 20, and the first massage movement 10 is installed with the first anti-collision device 30, and the second massage movement 20 is installed with the second anti-collision device 40.
[0045] In this embodiment, the second anti-collision block 402 is made of elastic material, which further absorbs the impact force generated when the first massage movement 10 collides with the second massage movement 20. The side where the second anti-collision block 402 and the first anti-collision block 302 collide is a convex arc surface, which increases the contact area between the second anti-collision block 402 and the first anti-collision block 302, and is more conducive to absorbing the impact force generated when the first massage movement 10 and the second massage movement 20 collide, thereby protecting the first massage movement 10 and the second massage movement 20.
[0046] This embodiment also provides a massage chair, such as Figure 5-8 As shown, it includes a left guide rail 601 and a right guide rail 602, and includes the protective device of the dual-movement massage chair as described above. Specifically, the two ends of the first massage movement 10 and the second massage movement 20 are slidably installed on the left guide rail 601 and the right guide rail 602. When the first massage movement 10 and the second massage movement 20 collide, the first anti-collision device 30 and the second anti-collision device 40 collide first. Specifically, the second anti-collision block 402 and the first anti-collision block 302 collide with each other, so that the walking of the first massage movement 10 and the second massage movement 20 is restricted, and the driving current of the walking motor of the first massage movement 10 and the second massage movement 20 increases. When the control box detects that the current increases until it exceeds the driving current threshold, the control box will immediately issue a control instruction to reverse the motors corresponding to the first massage movement 10 and the second massage movement 20, so that the first massage movement 10 and the second massage movement 20 move away from each other to avoid collision.
[0047] Embodiment 2
[0048] A protective device for a dual-movement massage chair is provided in this embodiment. Figure 9-12 As shown, it is more suitable for structures with smaller curvature of the guide rail. The difference from the first embodiment is that the first anti-collision device 30 is replaced by a third anti-collision device 50, as shown in FIG. Fig.10 As shown, the third anti-collision device 50 includes a third mounting seat 501, and the third anti-collision block 502 is installed on the third mounting seat 501. The third anti-collision block 502 is made of elastic material, and the side of the third anti-collision block 502 that abuts and impacts the second anti-collision block 402 is provided with an outwardly protruding arc surface.
[0049] This embodiment also provides a massage chair, such as Figure 11-12 As shown, the collision process of the second anti-collision device 40 and the third anti-collision device 50 is the same as the collision process of the first anti-collision device 30 and the second anti-collision device 40 described above, and will not be repeated here.
[0050] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable those skilled in the art to understand the content of the utility model and implement it, and they cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
