Abstract
Description
Technical Field
[0001] This utility model relates to the field of seating technology, specifically to a headrest and a seat. Background Technology
[0002] To improve chair comfort, existing gaming chairs and office chairs typically have headrests installed at the top of the backrest support to provide static support for the user's head. However, as people's living standards continue to improve, headrests that only provide static support are no longer sufficient. Some chairs now have massage mechanisms installed inside the headrests. While the headrest provides support, the massage heads in these mechanisms massage the user's head. However, the massage heads in existing massage mechanisms can only rotate around a specific axis. Because the surface shape of the human head is complex, a massage head rotating around a single axis cannot adapt to the complex curvature of the head when pressing on it. This results in the massage head applying excessive pressure to certain parts of the head during the massage, thus affecting comfort. Utility Model Content
[0003] The purpose of this invention is to provide a headrest and seat that can avoid applying excessive pressure to the user's head during massage, thereby improving the comfort of the headrest.

[0028] like Figure 1 , 2 As shown in figures 3, 4, 5, and 6, this utility model discloses a headrest, particularly a headrest with a massage function. It includes a shaping cotton 10 and a massage mechanism installed inside the shaping cotton 10. The front side of the shaping cotton 10 forms a support surface 11 for supporting the user's head. The shaping cotton 10 has a flexible structure, allowing the support surface 11 to provide flexible support to the user's head. The massage mechanism includes a housing 20, a drive unit located inside the housing 20, and a massage head assembly. The drive unit drives the massage head assembly to rotate. In some embodiments, the drive unit consists of a motor and a reducer. The input end of the reducer is connected to the output shaft of the motor, and the output end is connected to the massage head assembly. The device includes a rotating shaft 30, a support 40, and a massage head 50. The rotating shaft 30 is pivotally connected to the housing 20 and extends in the front-to-back direction. Its rear end extends into the housing 20 and connects to the output end of a drive unit. The drive unit drives the rotating shaft 30 to rotate around its central axis O1. The support 40 is mounted on the rotating shaft 30, allowing it to rotate with the shaft. The support 40 has a pivot portion offset from the central axis O1. The massage head 50 has a rotating portion that engages with the pivot portion, allowing the massage head 50 to oscillate relative to the support 40 around an axis O2. The axis O2 forms an angle α with the central axis O1, where the angle α is 90°.
[0029] In this invention, the driving component drives the rotating shaft 30 to rotate, and the bracket 40 rotates with the rotating shaft 30, causing the massage head 50 to rotate around the central axis O1, so that the massage head 50 massages the user's head. During the rotation of the massage head 50 around the central axis O1 with the bracket 40, the pivot part on the bracket 40 cooperates with the rotating part on the massage head 50, so that the massage head 50 has the freedom to swing around the axis O2 relative to the bracket 40. Thus, when the massage head 50 rotates to massage the user's head, the massage head 50 with the freedom to swing laterally can adapt to the more complex shape of the user's head, avoid the massage head 50 applying too much pressure to the user's head, and improve the comfort of the headrest.
[0030] In this invention, the included angle α is preferably set to 90° so that the massage head 50 can swing laterally during rotation. In fact, in some embodiments, the included angle α only needs to be set to be greater than 0 to achieve the lateral swing of the massage head 50 during rotation. It should be noted that in the preferred embodiment, the above-mentioned axis O2 and the central axis O1 are set on the same plane so that the massage head 50 can swing laterally in a more balanced manner when rotating. In other embodiments, the axis O2 and the central axis O1 may also be on different planes.
[0031] The aforementioned pivot portion is a shaft head 43 mounted on the support 40. The axis O2 is the central axis of the shaft head 43. A receiving groove 51 is provided on the massage head 50. The front end wall 511 of the receiving groove 51 is arc-shaped, matching the outer peripheral surface shape of the shaft head 43. Thus, the arc-shaped front end wall 511 forms a rotating part at the front end of the receiving groove 51, and an opening 512 is formed at the rear end of the receiving groove 51. The shaft head 43 can be inserted into the receiving groove 51 through the opening 512, so that the shaft head 43 is placed at the front end of the receiving groove 51 and pivotally engaged with the arc-shaped front end wall 511. The support 40 includes a sleeve portion 41 sleeved on the rotating shaft 30 and a connecting arm 42 protruding outward from the periphery of the sleeve portion 41. The shaft head 43 is mounted on the connecting arm 42, which has a certain length dimension, so that the shaft head 43 is offset from the central axis O1 by a certain distance.
[0032] The connecting arm 42 is fitted into the opening 512 of the receiving groove 51. The width of the connecting arm 42 is smaller than the width of the opening 512 of the receiving groove 51, that is, the connecting arm 42 and the receiving groove 51 are in clearance fit. The clearance is sufficient to allow the connecting arm 42 to swing inside the receiving groove 51. When the massage head 50 rotates relative to the axis head 43, the connecting arm 42 swings between the two sides of the opening 512 of the receiving groove 51. In this way, the two sides of the connecting arm 42 are in cooperation with the two sides of the opening 512 of the receiving groove 51, which limits the angle range of the swing of the rotating part relative to the pivot part around the axis O2, that is, limits the angle range of the side swing of the massage head 50 relative to the support 40. In other words, the width of the connecting arm 42 and the width of the opening 512 of the receiving groove 51 can be set according to actual needs to adjust the amplitude of the side swing of the massage head 50 to an appropriate angle range.
[0033] When the bracket 40 rotates with the rotating shaft 30, the connecting arm 42 will abut against the side of the opening 512 of the receiving groove 51 to make the massage head 50 rotate. Therefore, in order to make the connection between the massage head 50 and the bracket 40 more stable and avoid stress concentration between the connecting arm 42 and the massage head 50, the bracket 40 includes two connecting arms 42 that protrude outward from its two sides respectively. Each of the two connecting arms 42 is provided with a shaft head 43. The two shaft heads 43 are coaxially arranged. The massage head 50 is provided with two opposing receiving grooves 51. The two shaft heads 43 are respectively embedded in the front end of the two receiving grooves 51.
[0034] The aforementioned pivot 30 and bracket 40 are assembled together in a modular manner to facilitate the assembly of the entire headrest; in other embodiments, the pivot 30 and bracket 40 may also be set as an integral structure to simplify the structure of the headrest.
[0035] To facilitate the connection of the massage head 50 with the rotating shaft 30 and the support 40, and to ensure that the massage head 50 can swing relative to the support 40 and the rotating shaft 30 around the axis O2, a ball head 60 is fixedly connected to the front end of the rotating shaft 30 or the support 40. The center line of the ball head 60 coincides with the central axis O1. The massage head 50 is provided with a rearwardly recessed ball socket 52, and the ball head 60 is embedded in the ball socket 52, so that the ball head 60 and the ball socket 52 are in universal rotational engagement. The rotation axis of the ball head 60 and the ball socket 52 falls on the axis O2. Through the engagement of the ball head 60 and the ball socket 52, the massage head 50 is in universal rotational engagement with the rotating shaft 30 and the support 40. At the same time, the ball head 60 can prevent the massage head 50 from moving forward freely, that is, prevent the massage head 50 from disengaging from the rotating shaft 30 and the support 40.
[0036] For ease of assembly, a screw hole is provided on the front end face of the rotating shaft 30. A screw 31 passes through the ball head 60. The screw 31 passes through the ball head 60 from front to back and is screwed into the screw hole of the rotating shaft 30, thereby detachably fixing the ball head 60 to the front end of the rotating shaft 30. During assembly, the massage head 50 is fitted onto the bracket 40, so that the shaft head 43 on the bracket 40 is inserted into the front end of the receiving groove 51 through the opening 512 of the receiving groove 51. The shaft head 43 fits against the front wall 511 of the receiving groove 51. Then, the ball head 60 is inserted into the ball socket 52 from front to back. Finally, the screw 31 passes through the ball head 60 from front to back and is screwed into the screw hole of the rotating shaft 30. The massage head 50 is installed on the rotating shaft 30 through the ball head 60, so that the ball head 60 is omnidirectionally mounted on the rotating shaft 30, thereby ensuring that the massage head 50 can swing relative to the bracket 40 around the axis O2.
[0037] In this invention, a groove 12 is provided on the shaping cotton 10, recessed from the support surface 11. The massage mechanism is embedded in the groove 12. The massage head 50 is provided with massage protrusions 501 and 502 located at the opening of the groove 12. A portion of the massage protrusion 501 protrudes from the support surface 11 of the shaping cotton 10, and the size of the massage protrusion 502 is smaller than the size of the massage protrusion 501. Alternatively, both the massage protrusions 501 and 502 can be set to protrude from the support surface 11 of the shaping cotton 10. In other embodiments, one or more massage protrusions may be provided on the massage head 50.
[0038] It should be noted that the present invention uses shaped cotton 10 as a support to provide support for the user's head, so that a flexible support surface 11 is formed on the front side of the headrest. In other embodiments, the support is not necessarily made of shaped cotton 10, but can be made of other flexible materials, such as cotton core, fabric, etc. Of course, the support is not necessarily a flexible structure, but can be made of rigid materials such as wood, plastic, etc.
[0039] In the above structure of this utility model, the massage head 50 is connected to the front end of the rotating shaft 30 through the universal rotation structure. The shaft head 43 on the bracket 40 cooperates with the massage head 50, and the rotation of the massage head 50 and the bracket 40 is limited to rotation around the axis O2. In other embodiments, the shaft head 43 can be set on the massage head 50, and the corresponding receiving groove 51 that cooperates with the shaft head 43 and the arc-shaped wall surface on the receiving groove 51 that cooperates with the shaft head 43 are set on the bracket 40.
[0040] In other embodiments, the connection between the massage head 50, the support 40, and the rotating shaft 30 does not depend on the engagement of the ball head 60 and the ball socket 52. Specifically, the pivot part can be a shaft hole provided on the support 40, and the rotating part is a pivot provided on the massage head 50. The pivot is detachably fixed to the massage head 50 and passes through the shaft hole. For example, after the massage head 50 is fitted onto the support 40, the pivot passes through the massage head 50, so that the pivot passes through the shaft hole of the support 40. The axis of the pivot is the axis O2.
[0041] The seat of this utility model includes the headrest described above. The other structures of the headrest are the same as those in the prior art and will not be described in detail here.
[0042] Finally, it should be noted that the above embodiments are only optional embodiments of this utility model and should not be used to limit the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
