[0060] In order to better understand the above technical solution, the technical solution of the embodiment of the present application is described in detail below through the accompanying drawings and specific embodiments. It should be understood that the embodiment of the present application and the specific features in the embodiment are detailed descriptions of the technical solution of the embodiment of the present application, rather than limitations on the technical solution of the present application. In the absence of conflict, the embodiment of the present application and the technical features in the embodiment can be combined with each other.

[0061] like Figures 1 to 11 As shown, according to the first aspect of an embodiment of the present application, a chair is proposed, comprising: a chair body 100; a lumbar pillow unit 400, which is arranged on the chair body 100, and a massage unit 600 is arranged in the lumbar pillow unit 400; wherein, the massage unit 600 comprises a first driving component 500, a massage shell and a plurality of massage protrusions 650, and the plurality of massage protrusions 650 are movably arranged in the massage shell, and the first driving component 500 is respectively connected to the massage shell and the plurality of massage protrusions 650, and is used to drive the massage shell to rotate when driving along a first rotation direction, and drive the massage protrusions 650 to move relative to the massage shell when driving along a second rotation direction.

[0062] In some examples, a surface of the massage shell facing away from the seat body 100 is provided with a plurality of through holes 640 arranged in an annular manner, and the massage protrusions 650 are correspondingly arranged in the through holes 640;

[0063] The chair provided in the embodiment of the present application includes a chair body 100 and a lumbar pillow unit 400. The lumbar pillow unit 400 is installed on the chair body 100, wherein the lumbar pillow unit 400 includes a first drive assembly 500, a massage shell and a plurality of massage protrusions 650. The first drive assembly 500 has two rotation directions when in operation: clockwise rotation and counterclockwise rotation. When the first drive assembly 500 is driven along one of the rotation directions, the massage shell can be controlled to rotate, and the plurality of massage protrusions 650 are driven to rotate together. The massage shell and the massage protrusions 650 rotate together to perform a rotational massage on the user sitting on the chair body 100, which is a first massage mode. When the first drive assembly 500 is rotated along the other rotation direction, the massage shell can be controlled to be fixed relative to the first drive assembly 500. At this time, when the first drive assembly 500 rotates, the plurality of massage protrusions 650 can move relative to the massage shell. At this time, the massage shell is fixed relative to the user sitting on the chair body 100, and the massage protrusions 650 protrude, performing a raised pressing massage on the user sitting on the chair body 100.

[0064] The present application implements the provided seat for massage. By controlling the rotation direction of the first drive component 500 during operation, two massage modes can be controlled, and the massage mode can be selected to improve the user experience.

[0065] like Figure 8 As shown, in some examples, the first drive assembly 500 further includes: a drive motor 510; a first driven part 520 and a second driven part 530, which are sequentially arranged on the output shaft of the drive motor 510; wherein the first driven part 520 is used to connect with the massage shell and drive the massage shell to rotate, and the second driven part 530 is used to drive the massage protrusion 650 to move relative to the massage shell.

[0066] In some examples, a second mounting slot 450 is provided on a side of the lumbar pillow unit 400 facing away from the chair body 100, and the drive motor 510 is disposed inside the second mounting slot 450. The massage housing includes: a bearing element 610, which is sleeved inside the second mounting slot 450; a first cylinder element 620, which is disposed inside the second mounting slot 450 and sleeved inside the bearing element 610, and can rotate inside the second mounting slot 450 via the bearing element 610; a massage element 630 is fixedly connected to one end of the first cylinder element 620 located outside the second mounting slot 450, and is configured to rotate with the first cylinder element 620;

[0067] In this technical solution, the first driven part 520 and the second driven part 530 are coaxially fixedly mounted on the output shaft of the driving motor 510 in sequence. The driving motor 510 is connected to the controller, and the controller is connected to the vehicle control system. The vehicle control system sends a signal to make the controller control the driving motor 510 to work. When the output shaft of the driving motor 510 is working and rotating, it drives the first driven part 520 and the second driven part 530 to rotate together. The output shaft of the driving motor 510 can rotate in two directions, clockwise and counterclockwise. When working in one of the rotation modes, the first driven part 520 is connected to the massage shell as a whole. When the first driven part 520 rotates, it drives the massage shell to rotate together. At this time, the second driven part 530 rotates together in the same direction. At this time, the rotation direction of the second driven part 530 does not drive the massage shell to move, thereby realizing rotary massage.

[0068] When the output shaft of the driving motor 510 is working in another rotation direction, the first driven part 520 is not connected to the massage shell as a whole due to the effect of the rotation direction. At this time, the massage shell is fixed relative to the first driven part 520. At this time, while the second driven part 530 rotates, it can control the multiple massage protrusions 650 to move along the massage shell to achieve protrusion pressing massage.

[0069] like Figure 10 and Figure 11 As shown, in some examples, a boss 540 is provided on the side surface of the second follower 530 facing the massage protrusion 650; when the second follower 530 rotates, the boss 540 passes through the area where the massage protrusion 650 is located to lift the massage protrusion; the massage unit 600 also includes a first elastic return member 660, which is provided between the massage protrusion 650 and the massage shell.

[0070] In this technical solution, the first elastic return member 660 can be a spring, which is installed between the massage protrusion 650 and the side wall of the through hole 640. The first elastic return member 660 always applies a force to the massage protrusion 650 to move toward the inside of the massage shell. When no external force is applied, the massage protrusion 650 always moves toward the inside of the massage shell under the action of the first elastic return member 660.

[0071] In this technical solution, a plurality of bosses 540 are equidistantly provided on the surface of the second driven portion 530 facing the massage protrusion 650, and one side surface of the massage protrusion 650 is an inclined surface. When the second driven portion 530 rotates under the drive of the driving motor 510, it can control the plurality of bosses 540 to rotate together. When the massage shell is fixed relative to the first driving component 500, the massage shell is also fixed relative to the second driving component and the boss 540. At this time, when the second driving portion and the plurality of bosses 540 rotate, when the plurality of bosses 540 pass through the area of ​​the massage protrusion 650, the inclined surface of the boss 540 contacts the massage protrusion 650, which can lift the massage protrusion 650 and move the massage protrusion 650 to the outside of the massage shell. When the boss 540 continues to move and does not contact the massage protrusion 650, the massage protrusion 650 is not subjected to external force at this time, and the massage protrusion 650 moves back to the initial position under the action of the first elastic return member 660, waiting for the next work.

[0072] like Figure 7 As shown, in some examples, it also includes: a first one-way locking assembly 700, which is arranged between the lumbar pillow shell of the lumbar pillow unit 400 and the massage shell; a second one-way locking assembly, which is arranged between the massage shell and the first driven part 520; wherein the locking rotation directions of the first one-way locking assembly 700 and the second one-way locking assembly are opposite.

[0073] In this technical solution, the first one-way locking component 700 is arranged between the lumbar pillow shell and the massage shell of the lumbar pillow unit 400, wherein the second one-way locking component is arranged between the massage shell and the first follower part 520. When the first follower part 520 and the second follower part 530 rotate in the same direction, only the first one-way locking component 700 or the second one-way locking component can be locked, thereby realizing the control of the first one-way locking component 700 or the second one-way locking component to achieve a locked state through forward and reverse rotation.

[0074] like Figure 7 As shown, in some examples, the first one-way locking assembly 700 includes: a first opening 710, the first opening 710 is opened in the lumbar pillow shell, facing the massage shell; a second elastic return member 720, passed through the first opening 710; a first limiting member 730, one end of which is connected to the free end of the second elastic return member 720; a first limiting groove 680, opened in the massage shell, so that when the second elastic return member 720 is in a restored state and the first opening 710 and the first limiting groove 680 are in corresponding positions, the first limiting member 730 is passed through the first limiting groove 680, and the first limiting member 730 is formed with a slope on one side surface along the radial direction of the drive assembly and the slope faces the massage shell.

[0075] In this technical solution, the first opening 710 is fixedly connected in the first limiting groove 680, and the first limiting member 730 is slidably installed in the first opening 710710 through the second elastic reset member 720. The second elastic reset member 720 can be a compression spring, which applies a force to the first limiting member 730 to move toward the massage shell in real time without being affected by external force, wherein the first limiting member 730 is formed with a slope on one side surface along the radial direction of the driving assembly and the slope faces the massage shell.

[0076] In this technical solution, when the first drive assembly 500 rotates in one direction and the second one-way locking assembly is locked, the massage housing can be driven to rotate together. The first limiting groove 680 of the first cylindrical element 620 can squeeze the inclined surface of the first limiting member 730, allowing the first limiting member 730 to enter the interior of the first opening 710, thereby not affecting the rotation of the first cylindrical element 620. At this time, the first cylindrical element 620 drives the massage element 630 and the massage protrusion 650 to rotate together to perform a rotational massage on the driver's waist.

[0077] When the first drive assembly 500 rotates in another direction, the second one-way locking assembly does not perform the locking work. At this time, the second one-way locking assembly does not drive the massage shell to rotate together. At this time, the massage shell is not affected by external force. Even if the massage shell rotates with the drive component, since the plane of the first limiting member 730 contacts the first limiting groove 680, the first limiting member 730 cannot move into the first opening 710. At this time, the rotation of the massage shell is restricted and locking is achieved. At this time, the massage shell is in a relatively fixed state relative to the first drive assembly 500.

[0078] like Figures 8 to 11 As shown, in some examples, the second one-way locking assembly includes: a second opening, which is opened in the massage shell and faces the first driven part 520; a sliding rod 671, which is arranged at the second opening along the radial direction of the driving assembly; a third elastic return member 672, which is sleeved on the sliding rod 671; a second limiting member 670, one end of which is passed through the sliding rod 671 and is connected to the free end of the third elastic return member 672; wherein, the first driven part 520 is a gear part, and the sliding rod 671 includes a first position and a second position, when the second limiting member 670 is in the first position, the other end of the second limiting member 670 is in contact with the gear 673 of the gear part, and when the second limiting member 670 is in the second position, the other end of the second limiting member 670 is away from the gear 673 of the gear part.

[0079] In this technical solution, the slide bar 671 is arranged at the second opening along the radial direction of the driving component, and the second limiting member 670 is slidably installed on the slide bar 671, wherein a third elastic reset member 672 is provided in the second opening, and the third elastic reset member 672 can be a tension spring, one end of which is connected to a side wall of the second opening, and the free end of the other end is connected to the second limiting member 670, so that the second limiting member 670 is applied in real time to move in the direction in which the third elastic member is connected to the side wall of the second opening. The end of the slide bar 671 where the third elastic member is connected to the side wall of the second opening is the first position, and the end of the slide bar 671 where the third elastic member is connected to the side wall of the second opening is the second position; both sides of the second limiting member 670 are inclined surfaces, and when the gear portion rotates in one rotation direction, the gear 673 of the gear portion is aligned with the second limiting member 67 0, the inclined surface contact can make the second limit member 670 move along the slide bar 671 in the direction away from the third elastic reset member 672, so that the second limit member 670 moves from the first position to the second position. When the second limit member 670 moves to the second position, since the gear part is rotating, the gear 673 of the gear part is no longer in contact with the second limit member 670. At this time, the second limit member 670 moves back to the first position under the action of the third elastic member, waiting for the next contact movement with the gear 673 of the gear part. This movement is the unlocked state of the second one-way locking assembly; when the gear part rotates in another opposite direction, since the second limit member 670 is in the first position, the distance between the second limit and the second opening side wall is short and it can no longer move along the slide bar 671. At this time, the second one-way locking assembly is locked.

[0080] like Figure 9 As shown, in some examples, the curvature of the sliding bar 671 is smaller than the curvature of the peripheral surface of the first driven portion 520 .

[0081] In this technical solution, the curvature of the sliding rod 671 is smaller than the curvature of the peripheral surface of the first driven portion 520, thereby enabling the second one-way locking assembly to operate smoothly.

[0082] like Figures 3 to 5 As shown, in some examples, the lumbar pillow unit 400 further includes: a second driving component 300 , and the second driving component 300 is used to drive the lumbar pillow unit 400 to move closer to or away from the seat body 100 .

[0083] In this technical solution, the second drive assembly 300 includes an airbag element 310 and a spring element 440; a first mounting groove 110 is defined in the middle of the seat body 100, and first slide grooves 120 are defined on both side walls of the first mounting groove 110; the lumbar pillow unit 400 includes a mounting plate element 410 and a support plate element 420 connected to each other. The support plate element 420 is disposed at the end of the mounting plate element 410, and has an arc-shaped longitudinal cross-section. When in use, the support plate element 420 contacts the user's waist; the mounting plate element 410 is disposed within the first mounting groove 110;

[0084] Sliders 430 are fixedly mounted on both sides of the mounting plate 410 and are slidably mounted in the first slide grooves 120. Spring elements 440 are provided inside the first slide grooves 120 and are connected to the slide elements 430. The two slide elements 430 are used to drive the support plate element 420 to reset. Rollers are provided on both side walls of the slide elements 430 to roll in contact with the first slide grooves 120 to facilitate the sliding of the lumbar pillow unit 400.

[0085] A second drive assembly 300 is also provided on the lumbar pillow unit 400. The second drive assembly 300 is arranged on the lumbar pillow unit 400 and is located inside the first mounting groove 110. The second drive assembly 300 includes: an airbag element 310. The airbag element 310 is arranged on the lumbar pillow unit 400 and is connected to an external inflatable element through a pipe / valve, such as an air pump, wherein the valve is arranged on the pipe to control the opening or closing of the pipe.

[0086] In this technical solution, the user inflates the airbag element 310 through an air pump, and the airbag element 310 pushes the mounting plate element 410 and the support plate element 420 to leave the first mounting groove 110, and squeezes the driver's waist through the support plate element 420, or changes the distance between the support plate element 420 and the side wall of the seat body 100 to support the driver's waist; when it is necessary to reduce the distance between the support plate element 420 and the side wall of the seat body 100, the driver deflates the airbag element 310 through the deflation valve, and then the spring element 440 pulls the support plate element 420 back through the two slider elements 430, thereby changing the distance between the support plate element 420 and the side wall of the seat body 100, so as to adapt to drivers with different needs.

[0087] like Figure 1 and Figure 2 As shown, it also includes: a neck pillow unit 200, the neck pillow unit 200 includes a neck pillow element 220 and a connecting belt 210, the pillow element 220 is provided with a first connecting position on the side close to the seat body 100, and the pillow element 220 is provided with a second connecting position on the side away from the seat body 100, and the connecting position 230 is used to fix the neck support assembly 240.

[0088] In this technical solution, a connecting belt 210 is provided on one side wall of the pillow element 220, and the pillow element 220 is mounted on the upper part of the seat body 100 through the connecting belt 210, and the neck pillow unit 200 is used to support the neck; wherein the pillow element 220 is provided with a first connecting position on the side close to the seat body 100, and the pillow element 220 is provided with a second connecting position on the side away from the seat body 100, wherein the first connecting position and the second connecting position can be movably connected to the neck support assembly 240, wherein the neck support assembly 240 is in a away from storage state when the first connecting position is installed, and the neck support assembly 240 does not play any role at this time and is in a storage state, and when the neck support assembly 240 is in the second connecting position, the neck support assembly 240 is used to support the neck of the user sitting on the seat body 100.

[0089] According to a second aspect of an embodiment of the present application, a vehicle is proposed, comprising: a seat as described in any of the above technical solutions.

[0090] The vehicle provided in the embodiment of the present application includes the seat of the above technical solution, and therefore has all the intended effects of the seat of the above technical solution.

[0091] The vehicle provided in the embodiment of the present application can be massaged through the lumbar pillow unit 400 during driving or parking. The lumbar pillow unit 400 is installed on the seat body 100, wherein the lumbar pillow unit 400 includes a first drive component 500, a massage shell and a plurality of massage protrusions 650. When the first drive component 500 is working, there are two rotation directions: clockwise rotation and counterclockwise rotation. When the first drive component 500 is driven in one of the rotation directions, it can control the rotation of the massage shell and drive the plurality of massage protrusions 650 to rotate together. The protrusions 650 rotate together to perform a rotational massage on the user sitting on the seat body 100. This is the first massage method. When the first drive component 500 rotates along another rotation direction, the massage shell can be controlled to be fixed relative to the first drive component 500.
