Description

Technical Field

[0001] This utility model relates to the field of massage chair technology, and more specifically, to a massage chair. Background Technology

[0002] Existing massage chairs typically have a single, universal massage mechanism installed within the backrest frame. This mechanism, driven by a motor, moves along a preset track to perform kneading, pounding, and other massage techniques on the user's waist, back, and other areas. However, the structure and function of this universal mechanism are relatively limited. When it moves to massage the waist or back, it cannot simultaneously provide an effective, targeted massage for the neck.

[0003] To address the issue of neck massage, stand-alone neck massagers have emerged on the market, such as U-shaped pillow massagers. However, these are completely independent of massage chairs, preventing users from enjoying both back and waist massages while simultaneously relaxing their necks, thus reducing the user experience. Furthermore, both universal mechanisms and stand-alone neck massagers often lack effective personalized adjustment mechanisms, making it difficult to adapt to different user heights. This results in inaccurate massage positions and insufficient fit, further diminishing the comfort and effectiveness of neck massage. Utility Model Content

[0023] Please refer to Figure 1 This embodiment provides a massage chair 100, including a chair frame 110, a lumbar and back massage mechanism 120 and a neck massage component 130 respectively disposed on the backrest 112 of the chair frame 110; the neck massage component 130 includes a guide rod 131, a slide 132, a drive unit 133 and a neck massage mechanism 134; the guide rod 131 is fixedly disposed on the chair frame 110 along the extension direction of the backrest 112 of the chair frame 110, the slide 132 is slidably disposed on the guide rod 131, and the drive unit 133 is drivenly connected to the slide 132 for driving the slide 132 to move along the guide rod 131; the neck massage mechanism 134 is connected to the slide 132 and includes a first massage head 1341 for massaging the neck; the lumbar and back massage mechanism 120 includes a second massage head 121 for massaging the back.

[0024] Specifically, such as Figure 1 As shown, the chair frame 110 includes a seat 111 and a backrest 112. The backrest 112 is inclined relative to the seat 111. Preferably, the backrest 112 is hinged to the seat 111 to adjust its tilt angle relative to the seat 111. The backrest 112 is respectively provided with a lumbar and back massage mechanism 120 and a neck massage component 130. The lumbar and back massage mechanism 120 includes a second massage head 121 for massaging the back, and its position can be moved up and down along the backrest 112 to correspond to the waist position of people of different heights. The neck massage component 130 is corresponding to the neck position of the human body.

[0025] like Figure 2 As shown, the neck massage component 130 includes a guide rod 131, which is fixedly mounted on the chair frame 110 along the extension direction of the backrest 112 and located in the middle of the chair frame 110. A slide seat 132 is slidably mounted on the outer wall of the guide rod 131, and the neck massage mechanism 134 is connected to the slide seat 132, enabling it to slide stably on the guide rod 131 and adjust its position.

[0026] In one possible implementation of this application, such as Figure 4As shown, the guide rod 131 has a groove 1311, which includes two sliding walls 1311a spaced apart from each other, and a connecting wall 1311b for connecting the two sliding walls 1311a. The two sliding walls 1311a are perpendicularly arranged on opposite sides of the connecting wall 1311b, making the groove 1311 a U-shaped groove; Figure 3 As shown, the slide block 132 has at least one pair of sliding parts, each including two pulleys 1321 arranged opposite to each other. The two pulleys 1321 are respectively arranged corresponding to two sliding walls 1311a, and their rolling surfaces are in contact with the sliding walls 1311a, allowing them to slide up and down along the sliding walls 1311a to drive the slide block 132 to slide along the guide rod 131. To improve the stability and accuracy of the pulleys 1321, a positioning post is also provided on the side of the slide block 132 facing the guide rod 131. A positioning hole is provided in the middle of the pulley 1321, and the pulley 1321 is sleeved on the outer periphery of the positioning post through the positioning hole.

[0027] This application does not impose any limitation on the specific number of sliding parts. Preferably, there are two pairs of sliding parts, which are respectively disposed at opposite ends of the slide block 132. Of course, the number of sliding parts can also be three pairs, four pairs, etc. This application does not impose any limitation on this, as long as the stable sliding of the slide block 132 can be guaranteed.

[0028] Of course, in addition to setting a sliding part in the slide block 132, the material of the slide block 132 can also be changed to a self-lubricating material. In this case, the pulley 1321 can be removed, and the slide block 132 can still slide stably along the guide rod 131. This application does not impose any restrictions on the specific sliding method of the slide block 132.

[0029] To further improve the motion stability and accuracy of the slide 132, such as Figure 2 As shown, the massage chair 100 also includes a drive unit 133. Optionally, the drive unit 133 is an electric push rod, such as... Figure 4 As shown, the slide 132 has a third lug 1323 on the side opposite to the guide rod 131. The third lug 1323 has a third mounting hole 1323a, and preferably there are two third lugs 1323. The end of the electric push rod has a fourth lug 1331, and similarly, preferably there are two fourth lugs 1331. The relative interval between the two fourth lugs 1331 is slightly smaller than the relative interval between the two third lugs 1323, so that the fourth lug 1331 can abut against the inner wall of the third lug 1323, thereby minimizing the assembly gap between the electric push rod and the slide 132 and improving assembly stability. The fourth lug 1331 has a fourth mounting hole 1331a coaxially arranged with the third mounting hole 1323a. The neck massage component 130 also includes a fastener 180, such as a pin or bolt, through which the third mounting hole 1323a and the fourth mounting hole 1331a are respectively passed, ensuring the stability of power transmission.

[0030] The neck massage mechanism 134 is connected to the slide 132 and includes a first massage head 1341 for massaging the neck. The first massage head 1341 and the second massage head 121 are both located on the same side of the backrest 112. The second massage head 121 and the first neck massage head 1341 have separate functions. They can operate independently or work simultaneously, allowing the user to enjoy a back massage while receiving targeted neck relaxation. The massage chair 100 includes a chair frame 110, a back massage mechanism 120 and a neck massage assembly 130 respectively disposed on the backrest 112 of the chair frame 110; the neck massage assembly 130 includes a guide rod 131, a slide 132, a drive unit 133, and the neck massage mechanism 134; the guide rod 131 is fixedly disposed on the chair frame 110 along the extending direction of the backrest 112, the slide 132 is slidably disposed on the guide rod 131, and the drive unit 133 is drivenly connected to the slide 132. The drive slide 132 moves along the guide rod 131, ensuring that the adjustment path of the neck massage mechanism 134 matches the height variation trajectory of the human neck, providing a stable height adjustment reference for users of different heights. The neck massage mechanism 134 is connected to the slide 132 and includes a first massage head 1341 for massaging the neck. The first massage head 1341 can be precisely adjusted in position with the slide 132 to ensure close contact with the user's neck. The back massage mechanism 120 includes a second massage head 121 for massaging the back. The second massage head 121 and the first massage head 1341 for the neck form a functional division. Both can operate independently or work simultaneously, allowing users to enjoy a back massage while receiving targeted neck relaxation. The massage chair 100 integrates the neck massage function into the main body of the massage chair 100, simultaneously providing neck and back massage, and allowing for precise adjustment of the massage position, thus improving the user experience.

[0031] In one possible implementation of this application, such as Figure 6 and Figure 7 As shown, the neck massage assembly 130 also includes a hinge seat 135, the side of the hinge seat 135 facing the guide rod 131 having a receiving groove 1351, the guide rod 131 being disposed in the receiving groove 1351; the edge of the hinge seat 135 is fixedly connected to the slide 132; the side of the hinge seat 135 away from the guide rod 131 is hinged to the neck massage mechanism 134.

[0032] Specifically, such as Figure 6 and Figure 7As shown, the hinge seat 135 has a receiving groove 1351 in the middle. The receiving groove 1351 is a through groove along the extension direction of the guide rod 131. The receiving groove 1351 wraps around and limits the guide rod 131, preventing the hinge seat 135 from shifting laterally or wobbling when it moves with the slide 132. The width of the hinge seat 135 is greater than the width of the guide rod 131, and similarly, the width of the slide 132 is also greater than the width of the guide rod 131. Therefore, both the hinge seat 135 and the slide 132 are provided with coaxially arranged positioning holes. Figure 5 As shown, the positioning hole is used to insert the fastener 140 to fix the hinge seat 135 and the slide 132, so that the guide rod 131 is located between the hinge seat 135 and the slide 132, thereby not affecting the neck massage mechanism 134 from sliding along the guide rod 131.

[0033] like Figure 6 As shown, the hinge seat 135 is hinged to the neck massage mechanism 134 on the side opposite to the guide rod 131. The neck massage mechanism 134 can rotate around the hinge point with the hinge seat 135 as the rotation point to adjust the direction of the neck massage mechanism 134 and the first massage head 1341. This allows the neck massage mechanism 134 to automatically adjust its angle according to the physiological curve of the user's neck, greatly improving the fit between the massage head and the neck and solving the problem of poor adaptability of traditional fixed-angle mechanisms to users of different body types.

[0034] Optionally, such as Figure 7 As shown, the hinge seat 135 has two relatively spaced first lugs 1352 on the side opposite to the guide rod 131. The two relatively spaced lugs form a symmetrical support structure, which can balance the lateral force generated when the neck massage mechanism 134 rotates, avoid force offset or structural deformation caused by single lug support, and improve the structural stability and service life of the hinge part; the first lugs 1352 are provided with first mounting holes 1352a, and the line direction connecting the two first mounting holes 1352a is perpendicular to the extension direction of the guide rod 131; the two first mounting holes 1352a are provided with first mounting holes 1352a. 2a is used to pass through the hinge shaft 136, that is, the hinge shaft 136 is set in the transverse direction; the coaxial mounting hole ensures that the hinge shaft 136 is not eccentric after installation, reduces jamming and wear during rotation, and improves the smoothness of angle adjustment; the neck massage mechanism 134 is hinged to the hinge shaft 136 and can rotate around the hinge shaft 136; ensuring that the rotation trajectory of the neck massage mechanism 134 is around the hinge shaft 136, its rotation trajectory can accurately match the physiological angle changes of the human neck's forward and backward tilting, greatly improving the fit between the massage head and the neck, and improving massage comfort.

[0035] Optionally, such as Figure 4 and Figure 5As shown, the neck massage assembly 130 also includes a support frame 137. The support frame 137 includes a second lug 1371 protruding towards the hinge seat 135. The second lug 1371 has a second mounting hole 1371a. The second lug 1371 can be attached to the first lug 1352, so that the first mounting hole 1352a and the second mounting hole 1371a are coaxially arranged. The hinge shaft 136 passes through the first mounting hole 1352a and the second mounting hole 1371a respectively. The side of the support frame 137 away from the hinge seat 135 has a mounting plane, and the neck massage mechanism 134 is fixedly connected to the mounting plane.

[0036] Specifically, such as Figure 5 As shown, there are two second lugs 1371. The two second lugs 1371 are arranged at a relative interval to balance the lateral force generated when the neck massage mechanism 134 rotates, avoid force offset or structural deformation caused by single lug support, and improve the structural stability and service life of the hinge. The relative interval between the two second lugs 1371 is greater than or less than the relative interval between the two first lugs 1352, so that the two second lugs 1371 can be attached to the outer wall or inner wall of the first lug 1352 respectively, further eliminating the assembly gap between the two and improving the connection stability and rotational stability of the two.

[0037] The first mounting hole 1352a and the second mounting hole 1371a are coaxially arranged to ensure that the hinge shaft 136 is not eccentric after it passes through, reducing jamming and wear during rotation and ensuring smooth angle adjustment. A flat mounting surface is provided on the side of the support frame 137 away from the hinge seat 135. Fasteners such as bolts and screws 140 are used to rigidly fix the neck massage mechanism 134 to the surface, ensuring that the neck massage mechanism 134 is accurately positioned and evenly stressed after assembly, avoiding tilting of the mechanism or displacement of the massage head due to uneven mounting surface. The support frame 137 can drive the neck massage mechanism 134 to rotate around the hinge shaft 136.

[0038] Optionally, such as Figure 7 As shown, angle adjustment parts 138 are respectively provided on the opposite sides of the first lug 1352; the angle adjustment part 138 includes a first limiting plate 1381 and a second limiting plate 1382 arranged at intervals. The first limiting plate 1381 has a first inclined surface 1381a on the side edge facing the first lug 1352, and the second limiting plate 1382 has a second inclined surface 1382a arranged opposite to the first inclined surface 1381a on the side edge facing the first lug 1352; when the neck massage mechanism 134 rotates around the hinge shaft 136, the first inclined surface 1381a and the second inclined surface 1382a respectively limit the opposite sides of the second lug 1371.

[0039] Specifically, the widths of both the first limiting plate 1381 and the second limiting plate 1382 are less than the distance from the first mounting hole 1352a to the guide rod 131, wherein the width direction is the direction of the line connecting the slide 132 and the hinge seat 135. Therefore, the arrangement of the first inclined surface 1381a and the second inclined surface 1382a will not interfere with the rotation of the second lug 1371.

[0040] like Figure 7 As shown, the first inclined surface 1381a gradually slopes inward toward the slide block 132 from the outer wall of the first limiting plate 1381. Similarly, the second inclined surface 1382a gradually slopes inward toward the slide block 132 from the outer wall of the second limiting plate 1382, so that the first inclined surface 1381a and the second inclined surface 1382a form an inverted V-shape. When the support frame 137 rotates around the hinge axis 136, after the second lug 1371 rotates upward by a preset angle, its side wall facing the first inclined surface 1381a can abut against the first inclined surface 1381a to limit its upward rotation. Similarly, after the second lug 1371 rotates downward by a preset angle, its side wall facing the second inclined surface 1382a can abut against the second inclined surface 1382a to limit its downward rotation.

[0041] This configuration ensures that the neck massage mechanism 134 always rotates within the optimal angle range to suit different users' necks, significantly improving massage fit and comfort. It should be noted that the rotation range of the neck massage mechanism 134 is determined by the angle between the first inclined plane 1381a and the second inclined plane 1382a. However, this application does not impose any limitation on the angle between the first inclined plane 1381a and the second inclined plane 1382a, and it can be adjusted according to actual rotation range requirements.

[0042] In one possible implementation of this application, such as Figure 4 and Figure 5 As shown, a torsion spring 150 is sleeved on the outer wall of the hinge shaft 136. One end of the torsion spring 150 abuts against the support frame 137, and the other end abuts against the hinge seat 135. The elastic abutment force of the torsion spring 150 can provide continuous damping for the rotation of the neck massage mechanism 134 around the hinge shaft 136. When the user's neck contacts the first massage head 1341, the neck massage mechanism 134 can rotate with the neck contour and compress the torsion spring 150. The restoring force of the torsion spring 150 reacts to the support frame 137, pushing the mechanism to fit tightly against the neck, further improving the reliability of the massage. In addition, the elastic characteristics of the torsion spring 150 can buffer the vibration and impact force generated by the neck massage mechanism 134 during the massage, avoiding neck discomfort caused by rigid contact and improving massage comfort.

[0043] Optionally, such as Figure 3As shown, the slide block 132 has a first oil felt groove 1322 on the side facing the guide rod 131. A first oil felt 160 is installed in the first oil felt groove 1322, and the first oil felt 160 is in contact with the first surface of the connecting wall 1311b of the guide rod 131. The first oil felt groove 1322 provides a fixed installation position for the oil felt, ensuring that the oil felt is always in contact with the guide rod 131. Its oil storage characteristics allow for the slow penetration of the lubricating medium, providing continuous lubrication for the sliding process of the slide block 132 along the guide rod 131, improving the smoothness of adjustment; at the same time, it reduces the wear caused by direct friction between the two, extending the service life of the guide rod 131 and the slide block 132.

[0044] Optionally, such as Figure 4 As shown, the hinge seat 135 has a second oil felt groove 1353 on the side facing the guide rod 131, and a second oil felt 170 is fitted inside the second oil felt groove 1353, with the second oil felt 170 in contact with the guide rod 131. In one specific embodiment of this application, there are two second oil felts 170, which are spaced apart and respectively in contact with the second surface of the connecting wall 1311b of the guide rod 131. Similarly, the oil storage characteristics of the second oil felt 170 allow for the slow penetration of the lubricating medium, providing continuous lubrication for the sliding process of the slide block 132 along the guide rod 131, improving the smoothness of adjustment; at the same time, it reduces wear caused by direct friction between the two, extending the service life of the guide rod 131 and the slide block 132.

[0045] The above description is merely an optional embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.

[0046] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.
