[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0023] Please see Figure 1-4An automatic massage head for a massage bed includes a frame 1 and a massage head 2. It also includes a horizontal drive mechanism 3 and a vertical drive mechanism 4 disposed inside the frame 1. A movable block 5 is slidably connected inside the frame 1. The vertical drive mechanism 4 is disposed inside the movable block 5. The massage head 2 is connected to the output end of the vertical drive mechanism 4. The vertical drive mechanism 4 includes a rack 41, which is slidably connected to the movable block 5. The horizontal drive mechanism 3 drives the movable block 5 to move along the frame 1, and the vertical drive mechanism 4 drives the massage head 2 to maintain vertical movement. A Hall switch 51 is disposed on the movable block 5, and a magnetic block 42 is disposed on the rack 41.

[0024] Specifically, frame 1 includes a front frame 11 and a rear frame 12, which are fixedly connected by screws. Slide grooves 13 are provided on the inner walls of both the front and rear frames 11 and 12. The slide grooves 13 are horizontally arranged. Movable blocks 5 are slidably connected to the outer walls on opposite sides of the slide grooves 13. Limit switches 14 are provided at both ends of the slide grooves 13 on the front frame 11. The horizontal drive mechanism 3 includes a first drive motor 31, a drive wheel 32, a driven wheel 33, and a connecting bar 34. Figure 1 As shown, the first drive motor 31 is fixedly installed on the outer wall of one side of the frame 1. Specifically, the first drive motor 31 is fixedly installed on the outer wall of one side of the rear frame 12, and the output end of the first drive motor 31 passes through and extends into the interior of the rear frame 12. The drive wheel 32 is fixedly installed on the output end of the first drive motor 31. The driven wheel 33 is rotatably connected to the other end of the frame 1 via a rotating shaft. Specifically, the driven wheel 33 is rotatably connected between the front frame 11 and the rear frame 12 via a rotating shaft. One end of the connecting strip 34 is fixedly connected to the outer wall of one side of the movable block 5, and the other end of the connecting strip 34 is fixedly connected to the outer wall of the other side of the movable block 5. The connecting strip 34 maintains a transmission connection with the drive wheel 32 and the driven wheel 33. As an embodiment provided by this utility model, the drive wheel 32 and the driven wheel 33 are sprockets, and the connecting strip 34 is a chain. The first drive motor 31 drives the drive wheel 32 to rotate, which in turn drives the connecting bar 34 to rotate, thereby moving the movable block 5 within the slide groove 13. Ultimately, this allows for adjustment of the massage head 2's position within the frame 1. A limit switch 14 is provided to engage with the guide wheel 52, providing a limit for the movable block 5.

[0025] As a further embodiment provided by this utility model, such as Figure 4 and Figure 3As shown, the vertical drive mechanism 4 includes a second drive motor 43, a reducer 44, and a drive gear 45. The reducer 44 is fixedly installed inside the movable block 5. The second drive motor 43 is fixedly installed on the outer wall of the reducer 44, and the output end of the second drive motor 43 is fixedly connected to the input end of the reducer 44. The output end of the reducer 44 passes through the movable block 5. The drive gear 45 is fixedly installed on the output end of the reducer 44. A fixing plate 53 is fixedly installed on the outer wall of the movable block 5. A rack 41 is slidably connected to the movable block 5. The rack 41 is slidably connected between the fixed plate 53 and the movable block 5. The Hall switch 51 is fixedly connected to the movable block 5 via the fixed plate 53. The drive gear 45 meshes with the rack 41. The second drive motor 43 drives the reducer 44 to rotate, and the reducer 44 drives the drive gear 45 to rotate. The rotation of the drive gear 45 drives the rack 41 to move on the movable block 5, thereby driving the massage head 2 mounted at the end of the rack 41 to move vertically up and down on the movable block 5, ultimately achieving adjustable massage intensity. Preferably, there are two drive gears 45, which are symmetrically arranged on both sides of the movable block 5. The number of racks 41 is adapted to the number of drive gears 45.

[0026] Furthermore, such as Figure 4 As shown, guide wheels 52 are provided on the outer walls of the movable block 5. There are two guide wheels 52 on each side. The two guide wheels 52 are symmetrically distributed on one side of the outer wall of the movable block 5. The movable block 5 is slidably connected to the slide groove 13 through the guide wheels 52 provided on the outer wall.

[0027] As an embodiment of this utility model, a tension adjustment unit 6 is connected to the connecting strip 34. The tension adjustment unit 6 includes a connecting rod 61 and a reverse threaded sleeve 62. There are two connecting rods 61. Both ends of the reverse threaded sleeve 62 are threaded, and the threads on both sides are in opposite directions. One end of one connecting rod 61 is threaded to one end of the reverse threaded sleeve 62, and one end of the other connecting rod 61 is threaded to the other end of the reverse threaded sleeve 62. The end of the connecting rod 61 away from the reverse threaded sleeve 62 is connected to the connecting strip 34. Specifically, the tension adjustment unit 6 is connected in series on the connecting strip 34. By rotating the reverse threaded sleeve 62, the connecting rods 61 on both sides can be driven to move towards each other or away from each other, thereby adjusting the tension of the connecting strip 34.

[0028] This utility model allows the movable block 5 to move within the frame 1 via a horizontal drive mechanism 3, thus adapting to users of different heights. The vertical drive mechanism 4 on the movable block 5 drives the rack 41 to move, adjusting the position of the massage head 2 to provide different massage intensities. The Hall switch 51 on the movable block 5 can detect the position of the magnetic block 42 on the rack 41, enabling adjustable massage intensity levels for ease of use.

[0029] Working principle:

[0030] During use, when adjustments are needed based on the user's height, the first drive motor 31 of the horizontal drive mechanism 3 drives the drive wheel 32 to rotate. The rotation of the drive wheel 32 drives the connecting bar 34 to rotate, thereby driving the movable block 5 to slide inside the frame 1 and driving the massage head 2 to move on the frame 1, thus adapting to the massage position of users of different heights.

[0031] When it is necessary to adjust the massage intensity, the second drive motor 43 of the vertical drive mechanism 4 drives the reducer 44 to keep rotating, the reducer 44 drives the drive gear 45 to keep rotating, and the drive gear 45 drives the rack 41 to keep moving, so as to adjust the position of the massage head 2 on the movable block 5 and thus adjust the massage intensity.

[0032] A Hall switch 51 is provided on the outer wall of the movable block 5, and a magnetic block 42 is provided on the rack 41. The number of magnetic blocks 42 is several, and the several magnetic blocks 42 are arranged in a linear array. As an embodiment provided by this utility model, the number of magnetic blocks 42 is two. During use, the rack 41 is driven to slide by the second drive motor 43. The position of the magnetic block 42 can be detected by the Hall switch 51. Different gears can be selected by software, which is convenient for users to quickly switch.

[0033] It should be noted that the Hall switch 51 can detect the position of the magnetic block 42 and control the second drive motor 43 to stop rotating through software programming to achieve a fixed position. This is a conventional technical method and will not be elaborated here.

[0034] Those skilled in the art will understand that other similar connection methods can also achieve this utility model. For example, welding, bonding, or screwing.

[0035] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
