Technical Field
[0001] This utility model relates to the field of massage equipment technology, and in particular to a back massage device. Background Technology
[0002] Most existing back massage devices move along a fixed track, but the human back is not flat and at the same height everywhere. Just as the human spine has many curves, the massage head of the back massage device must also be able to rise and fall to accommodate the various heights of the back. Utility Model Content
[0003] The purpose of this invention is to overcome the shortcomings of the prior art by providing a back massage device that can adjust the position of the massage components according to the human back to better fit the human back.
[0004] The technical solution of this utility model is as follows: A back massage device includes a massage base and a massage machine. The massage base has a frame for accommodating the reciprocating movement of the massage machine. The massage machine has a massage seat, and an adjustment seat is slidably mounted on the massage base in a vertical direction. The adjustment seat has a recessed chamber, and a cover plate is provided on the top of the adjustment seat to cover the chamber. A massage component is provided on the cover plate. An adjustment motor and an adjustment component are provided in the chamber. The adjustment motor has a first engagement part, and the surface of the adjustment component has a second engagement part that engages with the first engagement part. The adjustment component has a screw rod axially mounted on it, which extends out of the bottom of the adjustment seat. The massage base has a threaded hole in a vertical direction that is helically engaged with the screw rod. The rotation of the adjustment motor drives the adjustment component to rotate, so that the screw rod moves along the threaded hole, thereby causing the adjustment seat to move vertically relative to the massage base.
[0005] By adopting the above technical solution, by adjusting the clockwise or counterclockwise rotation of the motor, and through the transmission of the first meshing part to the second meshing part, the adjusting part rotates clockwise or counterclockwise, driving the screw to move up or down along the screw hole, thereby raising or lowering the adjusting seat, and thus adjusting the force of the massage piece in contact with the human body and getting as close as possible to the human back.
[0006] In a further embodiment of this invention, the frame has a left frame and a right frame. The front and rear of the left and right frames are respectively connected to the front and rear frames. A frame opening is formed between the left, right, front, and rear frames.

After the drive motor drives the first or second rotating shaft to rotate, the first gear and the second gear move along the toothed rack. The first gear and the second gear respectively drive the lower curtain gear and the upper curtain gear to rotate the lower connecting rod and the upper connecting rod to roll up the lower curtain and the upper curtain respectively.
[0009] In a further improvement of this invention, the massage base is provided with several protruding ribs in the vertical direction, and the outer side of the adjustment seat is provided with several recessed grooves in the vertical direction, with the protruding ribs being engaged in the corresponding grooves.
[0010] The above-mentioned further design can serve as a guide, ensuring structural stability when the adjustment seat slides relative to the massage base, thus guaranteeing vertical movement.
[0011] In a further improvement of this invention, the left and right frames have the same structure, and there is a height difference between the front and rear ends of the left frame, with an angle formed at the intersection.
[0012] By adopting the above-mentioned further settings, the massage components can more accurately find the right position, avoiding excessive pressure during massage and reducing discomfort.
[0013] In a further improvement of this invention, the adjusting motor is a servo motor.
[0014] With the above-mentioned further settings, the number of rotations and angles can be precisely controlled by a program, thereby allowing for precise control over the height of the adjustable seat. Attached Figure Description

[0021] like Figure 1-8 As shown, a back massage device includes a massage base 10 and a massager 20. The massage base 10 has a frame 11 for accommodating the reciprocating movement of the massager 20. The massager 20 has a massage base 21, and an adjustment seat 22 is slidably mounted vertically on the massage base 21. The adjustment seat 22 has a recessed chamber 221, and a cover plate 23 is provided on the top of the adjustment seat 22 to cover the chamber 221. A massage element 24 is provided on the cover plate 23. An adjustment motor 222 and the adjustment element 223 are provided inside the chamber 221. The adjustment motor 222 has... The adjustment member 223 has a first engagement part 2221 and a second engagement part 2231 that engages with the first engagement part 2221. The adjustment member 223 has a screw 2232 axially arranged, which extends out of the bottom of the adjustment seat 22. The massage base 21 has a threaded hole 211 that is screwed to the screw 2232 in the vertical direction. The adjustment motor 222 drives the adjustment member 223 to rotate, so that the screw 2232 moves along the threaded hole 211, thereby driving the adjustment seat 22 to move vertically relative to the massage base 21.
[0022] The massage base 21 is provided with a plurality of protruding ribs 212 in the vertical direction, and the outer side of the adjustment seat 22 is provided with a plurality of recessed grooves 224 in the vertical direction. The protruding ribs 212 are engaged in the corresponding grooves 224, which can play a guiding role, so that the structure is stable when the adjustment seat 22 slides relative to the massage base 21, and can ensure vertical movement.
[0023] By adjusting the clockwise or counterclockwise rotation of the motor 222, and through the transmission of the first engagement part 2221 to the second engagement part 2231, the adjusting member 223 rotates clockwise or counterclockwise, driving the screw 2232 to move up or down along the screw hole 211, thereby raising or lowering the adjusting seat 22, and thus adjusting the force of the massage member 24 in contact with the human body and making it as close as possible to the back of the human body.
[0024] The adjustment motor 222 is a servo motor, which can precisely control the number of rotations and angles by programming, thereby accurately controlling the height of the adjustment seat 22.

The second rotating shaft 26 is pivotally connected to a second guide block that is respectively locked in the track 115. When the drive motor 27 drives the first rotating shaft 25 to rotate, the first gear 251 and the second gear 261 move along the toothed rack 116, thereby driving the massage machine 20 to move back and forth.
[0026] Of course, the drive motor 27 can also drive the second shaft 26 to rotate. When the drive motor 27 drives the second shaft 26 to rotate, the second gear 261 and the second gear move along the toothed row 116.
[0027] Another embodiment of this utility model differs in that, as Figure 3-6 As shown in Figure 8, a lower connecting rod 253 is pivotally provided between the first guide blocks, and a lower curtain 13 gear that meshes with the first gear 251 is provided on the left and right sides of the lower connecting rod 253. An upper connecting rod 263 is pivotally provided between the second guide blocks, and an upper curtain 14 gear that meshes with the second gear 261 is provided on the left and right sides of the upper connecting rod 263. The front frame 113 is fixed with a lower curtain 13 and rolled up on the lower connecting rod 253. The rear frame 114 is fixed with an upper curtain 14 and rolled up on the upper connecting rod 263. After the drive motor 27 drives the first rotating shaft 25 or the second rotating shaft 26 to rotate, the first gear 251 and the second gear 261 move along the gear rack 116. The first gear 251 and the second gear 261 respectively drive the gear of the lower curtain 13 and the gear of the upper curtain 14 to rotate the lower connecting rod 253 and the upper connecting rod 263 to roll up the lower curtain 13 and the upper curtain 14 respectively.
[0028] like Figure 1 As shown, the left frame 111 and the right frame 112 have the same structure. There is a height difference between the front end and the rear end of the left frame 111. The front end is set lower than the rear end, and the rear end is set obliquely upward from front to back. The intersection of the front end and the rear end forms an angle.
