Detailed Implementation

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] like Figures 1 to 4 The present invention discloses a neck and back massage device, including a mounting shell 1, a movable slider 2 installed inside the mounting shell 1, a massage mechanism installed on the movable slider 2, and a U-shaped cover plate 3 covering the mounting shell 1. The mounting shell 1 has a mounting plane 4, and first racks 5 are respectively provided on both sides of the mounting plane 4. Second racks 6 that mesh with the first racks 5 are respectively provided on the left and right sides of the movable slider 2. The second racks 6 are elastically connected to the movable slider 2, and the movable slider 2 slides on the mounting plane 4.

[0026] The movable slider 2 has mounting chambers 7 on its left and right sides, and elastic components are installed in the mounting chambers 7. The elastic components are elastically connected to the second rack 6 and the movable slider 2 respectively. The second rack 6 passes through the mounting chamber 7 and meshes with the first rack 5, running inside and outside the mounting chamber 7. In use, when the movable slider 2 is pushed to move, the second rack 6 is blocked by the first rack 5 and forced to retract into the mounting chamber 7, realizing the movement of the massage mechanism; when the movable slider 2 stops moving, the second rack 6 meshes with the first rack 5 under the action of the elastic components, realizing the positioning of the massage mechanism.

[0027] The elastic component includes a return spring 8, a spring mounting post 9 disposed on the inner wall of the mounting chamber 7, and a spring mounting hole 10 disposed on the back of the second rack 6. One end of the return spring 8 is sleeved on the outside of the spring mounting post 9, and the other end of the return spring 8 is sleeved in the spring mounting hole 10. Of course, the spring mounting post 9 can be disposed on the inner wall of the mounting chamber 7 or on the back of the second rack 6, and the spring mounting hole 10 can be disposed on the back of the second rack 6 or on the inner wall of the mounting chamber 7. To improve operational stability, two sets of second racks 6 can be respectively provided on the left and right sides of the movable slider 2, and the second rack 6 and the first rack 5 can be elastically connected by two sets of elastic components.

[0028] The second rack 6 includes a rack seat 11 and a plurality of rack blocks 12 disposed on the rack seat 11. A limiting strip 13 is provided on the rack seat 11, and the limiting strip 13 is engaged with the inner wall of the mounting chamber 7. The limiting strip 13 facilitates the positioning of the second rack 6, improves operational stability, prevents excessive pressure on the elastic component from causing the second rack 6 to shift, and increases the running resistance of the moving slider 2.

[0029] The second rack 6 has buffer blocks 14 at its beginning and end. The height of the buffer blocks 14 is lower than that of the adjacent blocks 12. The buffer blocks 14 play a buffering and transitioning role, which makes it easier for the second rack 6 to engage or disengage from the first rack 5 when the sliding block 2 is working.

[0030] The outer surfaces of the first rack 5 and the second rack 6 are provided with wear-resistant layers to improve the service life of the first rack 5 and the second rack 6.

[0031] The bottom of the movable slider 2 is provided with a protrusion along the moving direction, and the mounting surface 4 is provided with a groove that matches the protrusion. This reduces the contact area between the movable slider 2 and the mounting surface 4, reduces resistance, achieves the guiding function, and improves the running stability of the movable slider 2.

[0032] The movable slider 2 is equipped with a mounting platform or has a mounting slot 15. The massage mechanism can be integrally molded and directly fixed to the mounting platform with screws. Figure 4 As shown, the movable slider 2 has a mounting groove 15. The mounting groove 15 can increase the installation space and is suitable for various models of massage mechanisms from different manufacturers.

[0033] The left and right sides of the movable slider 2 are respectively provided with anti-detachment platforms 16, and the inner side of the U-shaped cover plate 3 is pressed on the anti-detachment platform 16.

[0034] The mounting shell 1 and the U-shaped cover 3 also enclose the outer shell 17, which is a flexible shell. The flexible shell 17 can be filled with flexible materials such as sponge to improve user comfort.

[0035] The mounting housing 1 houses a drive mechanism for moving the movable slider 2, enabling automatic movement of the slider 2. The drive mechanism includes a cylinder 18, a solenoid valve 19, and an air pump 20. The output end of the solenoid valve 19 is connected to the input end of the cylinder 18 via a first air pipe, and the input end of the solenoid valve 19 is connected to the output end of the air pump 20 via a second air pipe. The output end of the cylinder 18 is hinged to the movable slider 2, enabling electrically controlled movement of the slider 2. Positioning slots are provided within the mounting housing for mounting the drive mechanism.

[0036] The massage mechanism includes a mechanism assembly 21 and a massage assembly 22. The massage head of the massage assembly 22 has a silver ion layer on its surface to reduce bacterial growth on the massage head.

[0037] The mounting housing 1 is provided with screw mounting posts 23, and the U-shaped cover plate 3 is provided with screw mounting holes 24 that are compatible with the screw mounting posts 23.

[0038] Of course, in order to enhance the aesthetics and prevent the mounting surface 4 from being exposed, cover plates can be added to the front and back of the movable slider 2 to cover the mounting surface 4, so that the cover plates can cover the mounting surface 4 during the sliding of the movable slider 2, preventing debris from falling onto the mounting surface 4.

[0039] Working principle: Under normal conditions, the first rack 5 and the second rack 6 mesh to achieve locking; when the movable slider 2 is pushed, the second rack 6 is squeezed back into the mounting chamber 7 by the first rack 5 under the action of the elastic component, and the first rack 5 and the second rack 6 disengage, so that the movable slider 2 can move.

[0040] like Figure 5 As shown, the neck and back massage device 25 of the present invention can be applied to a massage chair 26 and has a wide range of applications.

[0041] like Figure 6 As shown, the neck and back massage device 25 of the present invention can also be applied to the backrest 27, which occupies little space and is easy to use.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
