Description

Technical Field

[0001] The utility model relates to the field of massage appliances, in particular to a double-movement mechanism chair frame structure and a massage chair. Background Art

[0002] The double-movement mechanism massage chair is a commonly used massage chair at present. A double-movement mechanism chair frame structure of a massage chair is disclosed in the patent publication document CN217219485U. In this chair frame structure, two independently operating movement mechanisms are provided on the chair frame. Due to the setting of two independently operating movement mechanisms, although the operating parameters during the internal operation of the movement mechanisms can be set, it is impossible to completely avoid the collision interference between the movement mechanisms only by setting the operating parameters. There is no collision warning mechanism provided on the two movement mechanisms in the chair frame structure disclosed in CN217219485U. Therefore, the two movement mechanisms in this chair frame structure may have the problem of collision interference during operation. Summary of the Utility Model

[0003] In view of the above problems, the utility model provides a double-movement mechanism chair frame structure and a massage chair. By providing a collision Hall induction component capable of collision induction on the first movement mechanism and the second movement mechanism, when the collision Hall induction components on the first movement mechanism and the second movement mechanism come into contact with each other, the first movement mechanism and the second movement mechanism immediately stop moving closer to each other, avoiding collision between the first movement mechanism and the second movement mechanism.

[0004] The technical solution adopted by the utility model is as follows:

[0005] A double-movement mechanism chair frame structure includes a chair frame, a first movement mechanism and a second movement mechanism. The first movement mechanism and the second movement mechanism are both arranged on the chair frame. The structure further includes a collision Hall induction component. The collision Hall induction components are arranged on both the first movement mechanism and the second movement mechanism. The collision Hall induction component on the first movement mechanism is used to contact the collision Hall induction component on the second movement mechanism.

[0006] The collision Hall induction component includes a base, a collision rod, a spring, a magnet and a Hall detection board. The collision rod is rotatably arranged on the base. The spring is arranged inside the base. One end of the spring abuts against the collision rod, and the other end of the spring abuts against the base. A magnet is arranged inside the collision rod. The Hall detection board is arranged on the base. The Hall detection board is used to sense the movement of the magnet.

[0007] In this chair frame structure, a first movement mechanism and a second movement mechanism capable of independent movement are arranged on the chair frame. The first movement mechanism and the second movement mechanism can operate on the chair frame according to the set parameters.

[0008] In the chair frame structure of this species, collision Hall induction components are installed on both the first movement and the second movement. The Hall induction component on the first movement is used to contact the Hall induction component on the second movement. When the Hall induction component on the first movement collides and contacts the Hall induction component on the second movement, the first movement and the second movement immediately stop approaching each other.

[0009] In this structure, the collision Hall induction component includes a base, a collision rod, a spring, a magnet, and a Hall detection plate. The collision rods are used to contact each other (that is, the two collision Hall induction components contact through the collision rods). When the collision rods collide and contact each other, both collision rods will rotate. Since magnets are provided on the collision rods, the rotation of the collision rods can be sensed by the Hall detection plate. After the Hall detection plate senses the rotation of the collision rods, it immediately notifies the respective movements to stop moving or move in the reverse direction.

[0010] At the same time, in this collision Hall induction component, a spring is provided between the base and the collision rod. The presence of the spring can, on the one hand, allow the collision rod to return to its original position (i.e., the position before the contact collision) after stopping the collision contact, and on the other hand, the presence of the spring can achieve a flexible contact collision between the two collision rods, avoiding damage to the collision rods during the contact collision.

[0011] Optionally, it further includes a pin shaft. The pin shaft is rotatably provided on the base, and the collision rod is rotatably installed on the pin shaft through its own through hole. A circlip is provided at one end of the pin shaft.

[0012] The circlip provided at one end of the pin shaft can prevent the pin shaft from falling off the base during rotation.

[0013] Optionally, it further includes a cover plate. The cover plate is provided on the base.

[0014] The function of the cover plate is to cover the spring inside the base, thereby playing a certain protective role for the spring.

[0015] Optionally, a hook is provided at one end of the collision rod. The hook is used to contact the cover plate.

[0016] The hook is used to contact the cover plate. Since the spring has a tendency to eject the collision rod from the base, a hook is provided at one end of the collision rod. By using the hook to contact the cover plate, when the cover plate contacts the hook, the spring will no longer be able to continue to push the collision rod to rotate. Therefore, the presence of the hook and the cover plate can play a certain limiting role in the rotation amount of the collision rod.

[0017] Optionally, the collision rod is an L-shaped collision rod, and an embedding part is provided at one end of the collision rod. One end of the spring is fitted with the embedding part.

[0018] The embedding part on the specific collision rod is cylindrical, and one end of the spring is inserted and fitted with the cylindrical embedding part, which can improve the installation stability of the spring.

[0019] Optionally, an arc collision surface is provided on the collision rod.

[0020] The contact between the collision rods through the arc collision surface can reduce the wear when the collision rods collide with each other, and at the same time make the whole contact collision process smoother.

[0021] Optionally, a mounting plate is provided on the base, and the mounting plate is used for cooperation with the first movement or the second movement.

[0022] Optionally, a mounting groove is provided on the collision rod, and the magnet is arranged in the mounting groove.

[0023] Optionally, the mounting groove is a square mounting groove, and the magnet is a square magnet.

[0024] Specifically, the square magnet is completely embedded in the mounting groove of the collision rod to ensure the stable installation of the magnet.

[0025] A massage chair includes the double-movement chair frame structure as described above.

[0026] The beneficial effects of the present utility model are as follows: Collision Hall induction components are installed on both the first movement and the second movement. The collision Hall induction component on the first movement is used to contact the collision Hall induction component on the second movement. When the collision Hall induction component on the first movement collides and contacts the collision Hall induction component on the second movement, the first movement and the second movement immediately stop approaching each other.

Those skilled in the art can make similar promotions without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific implementation modes disclosed below.

[0035] Embodiment 1

[0036] As shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and

[0037] shown in the figures, a double-movement chair frame structure includes a chair frame 1, a first movement 2 and a second movement 3. The first movement 2 and the second movement 3 are both arranged on the chair frame 1. It also includes a collision Hall induction component. The collision Hall induction components are arranged on both the first movement 2 and the second movement 3. The collision Hall induction component on the first movement 2 is used to contact the collision Hall induction component on the second movement 3.

[0038] In this chair frame 1 structure, the first movement 2 and the second movement 3 that can move independently are arranged on the chair frame 1. The first movement 2 and the second movement 3 can operate on the chair frame 1 according to the set parameters.

[0039] In the structure of this chair frame 1, collision Hall induction components are installed on both the first movement 2 and the second movement 3. The Hall induction component on the first movement 2 is used to contact the Hall induction component on the second movement 3. When the Hall induction component on the first movement 2 collides and contacts the Hall induction component on the second movement 3, the first movement 2 and the second movement 3 immediately stop approaching each other.

[0040] In this structure, the collision Hall induction component includes a base 4, a collision rod 9, a spring 10, a magnet 8, and a Hall detection board 11. The collision rods 9 are used to contact each other (i.e., the two collision Hall induction components contact through the collision rods 9). When the collision rods 9 collide and contact each other, both collision rods 9 will rotate. Since a magnet 8 is provided on the collision rod 9, the rotation of the collision rod 9 can be sensed by the Hall detection board 11. After the Hall detection board 11 senses the rotation of the collision rod 9, it immediately notifies its respective movement to stop or move in the reverse direction.

[0041] At the same time, in this collision Hall induction component, a spring 10 is provided between the base 4 and the collision rod 9. The presence of the spring 10 can, on the one hand, allow the collision rod 9 to return to its original position (i.e., the position before the contact collision) after stopping the collision contact, and on the other hand, the presence of the spring 10 can achieve a flexible contact collision between the two collision rods 9, avoiding damage to the collision rod 9 during the contact collision.

[0042] As shown in Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 shown, it also includes a pin shaft 7. The pin shaft 7 is rotatably arranged on the base 4, and the collision rod 9 is rotatably installed on the pin shaft 7 through its own through hole. A snap ring 6 is provided at one end of the pin shaft 7.

[0043] The snap ring 6 provided at one end of the pin shaft 7 can prevent the pin shaft 7 from falling off the base 4 during rotation.

[0044] As shown in Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 shown, it also includes a cover plate 12. The cover plate 12 is arranged on the base 4.

[0045] The function of the cover plate 12 is to cover the spring 10 inside the base 4, thereby playing a certain protective role for the spring 10.

[0046] As shown in Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5As shown, a hook piece 902 is provided at one end of the collision rod 9, and the hook piece 902 is used to contact the cover plate 12.

[0047] The hook piece 902 is used to contact the cover plate 12. Since the spring 10 has a tendency to eject the collision rod 9 from the base 4, a hook piece 902 is provided at one end of the collision rod 9. By using the hook piece 902 to contact the cover plate 12, when the cover plate 12 contacts the hook piece 902, the spring 10 will no longer be able to continue to push the pile spraying rod to rotate. Therefore, the presence of the hook piece 902 and the cover plate 12 can play a certain limiting role in the rotation amount of the collision rod 9.

[0048] As attached Figure 1 、attached Figure 2 、attached Figure 3 、attached Figure 4 and attached Figure 5 As shown, the collision rod 9 is an L-shaped collision rod 9, and an embedding part 904 is provided at one end of the collision rod 9. One end of the spring 10 is fitted with the embedding part 904.

[0049] Specifically, the embedding part 904 on the collision rod 9 is cylindrical, and one end of the spring 10 is inserted and fitted with the cylindrical embedding part 904, which can improve the installation stability of the spring 10.

[0050] As attached Figure 1 、attached Figure 2 、attached Figure 3 、attached Figure 4 and attached Figure 5 As shown, an arc collision surface 901 is provided on the collision rod 9.

[0051] The collision rods 9 contact each other through the arc collision surface 901, which can reduce the wear when the collision rods 9 collide with each other, and at the same time make the entire contact collision process smoother.

[0052] As attached Figure 1 、attached Figure 2 、attached Figure 3 、attached Figure 4 and attached Figure 5 As shown, a mounting plate 5 is provided on the base 4, and the mounting plate 5 is used to cooperate with the first movement 2 or the second movement 3.

[0053] As attached Figure 1 、attached Figure 2 、attached Figure 3 、attached Figure 4 and attached Figure 5 As shown, a mounting groove 903 is provided on the collision rod 9, and the magnet 8 is arranged in the mounting groove 903.

[0054] As attached Figure 1 、attached Figure 2 、attached Figure 3 、attachedFigure 4 and attached Figure 5 As shown, the installation groove 903 is a square installation groove 903, and the magnet 8 is a square magnet 8.

[0055] Specifically, the square magnet 8 is completely embedded in the installation groove 903 of the collision rod 9 to ensure the stable installation of the magnet 8.
