[0026] Combined with the accompanying drawings in the embodiments of the present invention, the technical solutions in the embodiments of the present invention are clearly and completely described. Many specific details are set forth in the following description in order to fully understand the present invention, but the present invention can also be implemented in other ways different from those described herein. Those skilled in the art can make similar promotions without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0027] As Figures 1 - 5 shown, the present invention discloses a backrest mechanism for a bath assisting robot, including a first backrest structure 1, a second backrest structure 2 and a connection structure 3. The first backrest structure 1 and the second backrest structure 2 are separable and symmetrically arranged. Please refer to Figure 1 , the first backrest structure 1 includes a first U-shaped support tube 11 and a first backrest 12. The first backrest 12 is fixedly arranged in the middle of the first U-shaped support tube 11 to provide support for the user's back. The opening of the first U-shaped support tube 11 faces the second backrest structure 2, and the outer surfaces of both ends of the first U-shaped support tube 11 are smooth, so as to facilitate inserting both ends of the first U-shaped support tube 11 into the connection structure 3.

[0028] Please continue to refer to Figure 1 , the second backrest structure 2 includes a second U-shaped support tube 21 and a second backrest 22. The second backrest 22 is fixedly arranged in the middle of the second U-shaped support tube 21. The opening of the second U-shaped support tube 21 is opposite to the opening of the first U-shaped support tube 11, and first external threads 211 are provided at both ends of the second U-shaped support tube 21.

[0029] The first U-shaped support tube 11 and the second U-shaped support tube 21 are connected into one body through the connection structure 3. Please refer to Figure 3 and Figure 4 , the connection structure 3 includes a first connecting tube 31, a sleeve 32 and a second connecting tube 33. Taking Figure 4For example, a limiting ring 321 is integrally formed at the left end of the sleeve 32. The limiting ring 321 extends towards the axis direction of the sleeve 32, that is, the diameter of the limiting ring 321 is smaller than the diameter of the sleeve 32. An internal thread is provided at the right end of the sleeve 32. A boss 311 is provided at the left end of the first connecting pipe 31. The diameter of the boss 311 is larger than that of the first connecting pipe 31. An external thread is provided on the boss 311. During use, the boss 311 is arranged inside the sleeve 32, and the boss 311 is threadedly connected to the sleeve 32. The inner wall of the first connecting pipe 31 is smooth. One end of the first U-shaped support pipe 11 is inserted into the first connecting pipe 31 from the right end of the first connecting pipe 31.

[0030] Please continue to refer to Figure 4 , a baffle 331 is provided at the right end of the second connecting pipe 33. An internal thread is provided on the inner wall of the second connecting pipe 33. During use, the second connecting pipe 33 is threadedly connected to one end of the second U-shaped support pipe 21. The second connecting pipe 33 is inserted into the sleeve 32. At this time, the baffle 331 is also inside the sleeve 32, and the baffle 331 abuts against the limiting ring 321. That is, in this state, the second connecting pipe 33 cannot be removed from the left end of the sleeve 32.

[0031] During use, first insert the second connecting pipe 33 into the sleeve 32 and make the baffle 331 abut against the limiting ring 321. Then screw the boss 311 into the sleeve 32 and make the boss 311 abut against the baffle 331. Then screw the second connecting pipe 33 onto one end of the second U-shaped support pipe 21. Then rotate the first U-shaped support pipe 11 and the second U-shaped support pipe 21 to make them in the same plane. Then hold the sleeve 32 and rotate the first connecting pipe 31 to separate the first connecting pipe 31 from the sleeve 32. During this process, one end of the first U-shaped support pipe 11 is inserted into the first connecting pipe 31, thereby connecting the first U-shaped support pipe 11 and the second U-shaped support pipe 21 into one body.

[0032] It should be noted that during actual use, the first U-shaped support pipe 11 and the second U-shaped support pipe 21 cannot move horizontally along the axis direction of the sleeve 32, but rotate driven by the seat hip support structure. Therefore, during use, the inner wall of the first connecting pipe 31 can limit the rotation of the first U-shaped support pipe 11 and prevent the first U-shaped support pipe 11 from being pulled out of the first connecting pipe 31. Regarding the movement mode of the first U-shaped support pipe 11 and the second U-shaped support pipe 21, the applicant has protected it in the prior application documents and will not be elaborated here.

[0033] In order to relieve the head pressure of the user during bathing, such as Figure 2As shown in the figure, a backrest mechanism for a bath-assisting robot further includes a headrest structure 4. An installation groove 41 is provided at the bottom of the headrest structure 4, and a contact plate 42 extends vertically on one side of the installation groove 41. During use, first connect the first U-shaped support pipe 11 and the second U-shaped support pipe 21 in the above manner, and then cover the installation groove 41 outside the first U-shaped support pipe 11 and the second U-shaped support pipe 21. In other words, the upper parts of the first U-shaped support pipe 11 and the second U-shaped support pipe 21 are inserted into the installation groove 41. At this time, the contact plate 42 is in contact with the first backrest 12 and the second backrest 22. During use, a person's head leans on the headrest structure 4, and the contact plate 42 can prevent the headrest structure 4 from rotating and falling along the first U-shaped support pipe 11 and the second U-shaped support pipe 21.

[0034] Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
