[0019] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] Example 1: like Figures 1-6 As shown, one embodiment of the present invention provides an anti-pinch component, which is installed on a massage chair. The massage chair includes a seat 8 and a calf massage mechanism 9, including a plate 1, an elastic structure 2 and a pressure detection structure 3. Plate 1 is located between the chair seat 8 and the calf massage mechanism 9, and plate 1 is connected to the chair seat 8 through elastic structure 2; The pressure detection structure 3 is connected to the side of the seat 8 near the plate 1 and is used to detect pressure.

[0021] The plate 1 is placed between the seat 8 and the calf massage mechanism 9. A pressure detection structure 3 is set between the plate 1 and the seat 8. During the rotation and reset process of the calf massage mechanism 9, when a foreign object or small animal enters the area between the calf massage mechanism 9 and the seat 8, the elastic structure 2 between the plate 1 and the seat 8 is compressed so that the plate 1 comes into contact with the pressure detection structure 3. When the pressure detection structure 3 detects that the pressure has reached the set threshold, the calf massage mechanism 9 stops rotating to prevent small animals from being pinched and to reduce the occurrence of massage chair malfunctions.

[0022] The baffle 11 has flanges on its top and sides, and multiple horizontal and vertical ribs on its surface to enhance its strength.

[0023] According to one embodiment of the present invention, plate 1 includes a baffle 11 and an abutment block 12 connected to each other; The abutment block 12 is used to abut against the pressure detection structure 3.

[0024] According to one embodiment of this utility model, one side of the plate 1 is rotatably connected to the seat 8, and the other side abuts against the seat 8 via the elastic structure 2. Furthermore, the top of the plate 1 is rotatably connected to the seat 8, and its bottom abuts against the seat 8 via the elastic structure 2. When the calf massage mechanism 9 rotates and resets, if a foreign object or small animal enters the area between the calf massage mechanism 9 and the seat 8, the plate 1 rotates, and the elastic structure 2 is compressed.

[0025] Preferably, the anti-pinch assembly includes a pivot 6 and a hook 7; The pivot 6 is connected to the seat 8, and the hook 7 is attached to the pivot 6; Hook 7 is connected to baffle 11. There are two rotating shafts 6, and the ends of the two rotating shafts 6 that are far apart from each other are connected to the first connecting plate. The first connecting plate is detachably connected to the chair seat 8 by fixing bolts.

[0026] The hook 7 can be a ring hook or an open hook. When an open hook is used, the hook 7 can be made of plastic material with a certain deformation capability. Its opening size is slightly smaller than the diameter of the pivot 6. During installation, the hook 7 is pressed against the pivot 6, causing it to elastically deform and insert the pivot 6 into the receiving area inside the hook 7. At this time, the hook 7 returns to its original position. The size of the receiving area formed inside the hook 7 is larger than the diameter of the pivot 6, and the hook 7 can rotate relative to the pivot 6. The plate 1 rotates around the pivot 6. Preferably, the side of the baffle 11 near the seat 8 is connected to a support block. The support block abuts against the side wall of the pivot 6. After the hook 7 is hung on the pivot 6, the support block and the hook 7 cooperate to allow the hook 7 to rotate around the axis of the pivot 6.

[0027] When a ring hook is used, the size of the receiving area of ​​the ring hook is larger than the diameter of the pivot 6, allowing the pivot 6 to be directly disassembled from the seat 8, thereby separating the pivot 6 from the hook 7.

[0028] Preferably, the elastic structure 2 includes a cylindrical spring, one end of which is connected to the baffle 11, and the other end abuts against the seat 8. Optionally, both ends of the cylindrical spring are fixedly connected to the baffle 11 and the seat 8, respectively. This does not depart from the design concept of this utility model, and therefore should fall within the protection scope of this utility model.

[0029] The pressure detection structure 3 can be equipped with a push switch or a pressure sensor, etc.

[0030] According to one embodiment of the present invention, a strip-shaped enclosure 4 is connected to the bottom of the baffle 11, and the strip-shaped enclosure 4 is used to cover the gap between the baffle 11 and the seat 8.

[0031] The strip panel 4 is connected to the bottom of the baffle 11. In the initial state, the gap between the baffle 11 and the bottom of the seat 8 is relatively large, which makes it easy for foreign objects to enter and may cause the pressure detection structure to fail. Therefore, by installing the strip panel 4, the bottom gap is covered, reducing the probability of the anti-pinch component failure.

[0032] As shown in the figure, the chair seat 8 includes a base beam 81 and two symmetrically arranged vertical beams 82. A columnar spring abuts against the base beam 81. Preferably, multiple columnar springs are arranged at intervals along the length of the base beam 81. When the abutting block 12 abuts against the pressure detection structure 3, the strip-shaped baffle 4 is lower than the lower surface of the base beam 81, thus not interfering with the rotation of the baffle 11 while simultaneously blocking the bottom gap between the baffle 11 and the chair seat 8.

[0033] Preferably, a strip plate can be connected to each side of the baffle 11, and the distance between the two strip plates is less than the distance between the two vertical beams 82, so as not to affect the normal rotation of the baffle 11.

[0034] Of course, in this embodiment, flexible cloth strips can also be installed around the baffle 11 to cover the bottom gap and the surrounding gap. This does not deviate from the design concept of this utility model, and therefore should be within the protection scope of this utility model.

[0035] According to one embodiment of the present invention, the anti-pinch assembly further includes a limiting member 5, which is used to limit the rotation angle between the plate 1 and the pressure detection structure 3.

[0036] According to one embodiment of the present invention, the limiting member 5 includes a limiting hole 51 and a bolt 52; A limiting hole 51 is provided on plate 1, and bolt 52 passes through the limiting hole 51 to be fixedly connected to the seat 8.

[0037] Specifically, the limiting hole 51 includes a first strip hole and a second strip hole that are connected. The size of the first strip hole is larger than the size of the second strip hole. The bolt 52 includes a head and a threaded part that are connected. The threaded part of the bolt 52 passes through the second strip hole and is connected to the bottom beam 81 on the seat 8. The head of the bolt 52 is accommodated in the first strip hole, but its head cannot pass through the second strip hole. The length direction of the first strip hole is the same as the length direction of the second strip hole. The length direction of the first strip hole is perpendicular to the rotation direction of the baffle 11.

[0038] Furthermore, a through hole is provided on the bottom beam 81 of the seat 8. The threaded part of the bolt 52 passes through the second strip hole, the first nut, the through hole and the second nut in sequence. The first nut and the second nut are both screwed to the threaded part. The bolt 52 is fixed to the bottom beam 81 of the seat 8 by the first nut and the second nut, which facilitates disassembly.

[0039] Of course, in this embodiment, a pin that engages with the thread of the bolt 52 can also be provided to fix the bolt 52 on the bottom beam 81. The pin is fixedly connected to the bottom beam 81. The pin has an internal threaded hole that matches the bolt 52. The threaded part of the bolt 52 is screwed into the internal threaded hole to fix the bolt 52. The purpose of this embodiment does not deviate from the design concept of this utility model. Therefore, it should fall within the protection scope of this utility model.

[0040] A sealing cap 53 is provided on the baffle 11 for sealing the limiting hole 51. Preferably, the sealing cap 53 is made of rubber. The sealing cap 53 can be directly embedded into the end of the first strip hole away from the second strip hole. This can protect the bolt 52 and prevent foreign objects from entering the first strip hole, which would prevent the bolt 52 from moving smoothly in the limiting hole 51.

[0041] Example 2: A massage chair includes an anti-pinch component, a seat 8, and a leg massage mechanism 9. The seat 8 includes a seat body having a base beam 81 and two symmetrically arranged vertical beams 82, and a pivot 6 is connected to the vertical beams 82 via a first connecting plate.

[0042] It should be noted that the seat 8 contains a controller and an alarm bell. The pressure detection structure 3 is electrically connected to the controller. When the pressure detection structure 3 detects that the pressure has reached the set threshold, it sends a signal to the controller. The controller then controls the alarm bell to sound, alerting people that a foreign object has entered between the seat 8 and the calf massage mechanism 9. At the same time, the controller controls the calf massage mechanism 9 to stop rotating, which can prevent small animals from being pinched and reduce the probability of the massage chair malfunctioning.
