[0036] As shown in Figure 1 Figure 7 A kind of anti-pinch physiotherapy bed, including bed frame main body 1, backrest lower shell 2, backrest main body 3, anti-pinch switch 4 and drive mechanism 5, the backrest main body 3 rotationally connects on the bed frame main body 1, the drive mechanism 5 is used to drive the backrest main body 3 rotation, the backrest lower shell 2 is installed on the bed frame main body 1 by multiple buoyancy units 6 in the way of being able to float up and down, and the backrest lower shell 2 is located below the backrest main body 3, when the backrest main body 3 rotates to horizontal, the backrest main body 3 and the bottom plate 21 of the backrest lower shell 2 are not in contact, one or more anti-pinch switches 4 are provided between the bed frame main body 1 and the bottom plate 21 of the backrest lower shell 2.
[0037] In the embodiment, the buoyancy unit 6 includes anti-pinch spring 61 and pin shaft 62, the anti-pinch spring 61 is sleeved on the pin shaft 62, the lower end of the pin shaft 62 is installed on the bed frame main body 1, when the backrest lower shell 2 moves downward and compresses the anti-pinch spring 61, the upper end of the pin shaft 62 can pass through and extend out of the backrest lower shell 2 upward. Through the compression and release of anti-pinch spring 61, the stable floating of backrest lower shell 2 is ensured. Of course, the buoyancy unit 6 can also use nitrogen spring, as long as the buoyancy unit 6 can make the backrest lower shell 2 can be self-adaptive adjustment according to the weight of load (such as foreign matter or animal) should be within the protection scope of the present application.
[0038] The anti-pinch physiotherapy bed further comprises one or more rear support seats 7, the lower end of the rear support seat 7 being fixed on the bed frame body 1, the upper end of the rear support seat 7 penetrating and extending out of the bottom plate 21 of the backrest lower shell 2, and the upper end of the rear support seat 7 supporting the backrest body 3 when the backrest body 3 falls flat, the upper end of the rear support seat 7 being a rubber seat in a cylindrical structure, which not only increases the friction force of the contact surface with the backrest body 3 to prevent sliding, but also protects the backrest body 3 and the backrest lower shell 2 through the buffering characteristics of rubber, and reduces noise and abrasion caused by direct contact. When the backrest body 3 is turned to a horizontal state, the rear support seat 7 can stably support the rear end of the backrest body 3, ensure that a gap in the vertical direction is maintained between the backrest body 3 and the bottom plate 21 of the backrest lower shell 2, thereby effectively preventing direct contact therebetween and ensuring that the anti-pinch switch 4 is not triggered when a user lies down.
[0039] In the embodiment, the driving mechanism 5 comprises a sliding frame 51, an electric support rod 52 and a connecting rod mechanism, the sliding frame 51 is slidingly installed on the bed frame body 1 through sliding rails at the bottom of the bed frame body 1, the electric support rod 52 is connected with the sliding frame 51 and used for driving the sliding frame 51 to move, and the bed frame body 1 is connected with the sliding frame 51 through the connecting rod mechanism. The electric support rod 52 drives the backrest body 3 to realize lifting or angle adjustment through the connecting rod mechanism, the electric support rod 52 comprises a driving shaft, an outer sleeve and a driving motor, the driving shaft can be telescopic in the outer sleeve, the driving motor drives the telescopic shaft to be telescopic, and the outer sleeve is hinged on the bed frame body 1.
[0040] In the embodiment, the two groups of connecting rod mechanisms are symmetrically arranged on the two sides of the backrest body 3. The symmetrically arranged connecting rod mechanisms make the lifting of the backrest body 3 more stable, the force on the two sides is uniform, and the problems of inclination or deformation caused by excessive force on one side are avoided. Each group of the connecting rod mechanisms comprises a first connecting plate 53 and a second connecting plate 54, one end of the first connecting plate 53 is pinned to the sliding frame 51, the other end of the first connecting plate 53 is pinned to one end of the second connecting plate 54, and the other end of the second connecting plate 54 is pinned to the backrest body 3 and the bed frame body. The first connecting plate 53 is an arc-shaped connecting plate.
[0041] The anti-pinch principle of the anti-pinch physiotherapy bed is as follows:
[0042] In the operation process, when the driving shaft of the electric support rod 52 extends outward, it pushes the sliding frame 51 to slide to the rear end, the sliding action is transmitted through the connecting rod mechanism, and the backrest body 3 is driven to stably rise upward; on the contrary, when the driving shaft of the electric support rod 52 is retracted, the sliding frame 51 moves to the front end, and through the linkage action of the connecting rod mechanism, the backrest body 3 is caused to slowly descend.
[0043] If there is a foreign object (such as small animals or objects not noticed) on the back lower shell 2 during the process, when the back body 3 is pressed down, the anti-pinch spring 61 of the back lower shell 2 is compressed, the back lower shell 2 is lowered and the anti-pinch switch 4 is triggered. Once the anti-pinch switch 4 is touched, the system will respond immediately to stop the electric support rod 52 drive shaft from continuing to retract, thereby preventing the back body 3 from further descending and avoiding unnecessary harm to the foreign object. Subsequently, the drive shaft of the electric support rod 52 will automatically extend, through the reverse action of the sliding frame 51 and the connecting rod mechanism, to make the back body 3 rise again and away from the foreign object, ensuring the safety of the entire physiotherapy bed and the user's peace of mind.
[0044] The anti-pinch physiotherapy bed of the utility model, if there is a foreign object (such as clothes, books, toys, etc.), small animals (such as pet cats, dogs, etc.) or the user inadvertently places his hand on it, due to its own weight or during the process of the back body 3 descending, these foreign objects, animals or hands may be pressed by the descending back body 3, compressing the buoyancy unit 6 below the back lower shell 2, the back lower shell 2 will correspondingly fall, when the buoyancy unit 6 is compressed to a certain extent, the back lower shell 2 will touch the anti-pinch switch 4 installed between the bed frame body 1 and the bottom plate 21 of the back lower shell 2. This touch action will immediately trigger the safety mechanism to stop the drive mechanism 5 from driving the back body 3 to descend, and automatically start the lifting function, thereby lifting the back body 3, effectively avoiding the injury of foreign objects, animals or hands, and ensuring the safety of use.
[0045] The above is only the preferred embodiment of the utility model, and is not used to limit the utility model, any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the utility model should be included in the protection scope of the utility model.
