Description

Technical Field

[0001] This utility model relates to the field of seating technology, specifically to a seat support component and a seat. Background Technology

[0002] Existing office chairs, gaming chairs, and study chairs typically include headrests, lumbar support, and other support components to prevent the user's body from being unsupported, thus relieving fatigue. However, as people's living standards improve, simple support is no longer sufficient to meet their demands for chair comfort. Therefore, massage mechanisms are often installed inside these support components to provide massage to specific areas of the user's body during use. These massage mechanisms are usually located inside the support components and are driven by a motor and a transmission mechanism. This allows the massage mechanism to move forward when needed and retract when not in use. The transmission mechanism is typically a lead screw mechanism, and the axis of the transmission mechanism and motor is aligned with the front-to-back direction. This results in the drive motor and the transmission mechanism between the massage mechanism and the drive motor occupying a significant amount of space in the front-to-back direction, leading to a longer front-to-back dimension and larger volume for the support components such as the headrest and lumbar support, which is detrimental to the spatial layout of other components in the chair. Utility Model Content

[0003] The purpose of this utility model is to provide a support component and a seat, which enables the support component to have a relatively small front-to-back size and volume, which is beneficial to the spatial layout of various components on the seat.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] The seat's support components include an outer frame, bracket, movable seat, height-adjustable seat, drive mechanism, and massage mechanism;

[0006] A flexible shielding part is provided on the front side of the outer frame, and the outer frame and the rear side of the flexible shielding part form an accommodating space, in which the bracket, movable seat, lifting seat, drive mechanism and massage mechanism are all located;

[0007] The bracket is fixedly fitted to the outer frame. The movable seat is located on the front side of the bracket and is movably fitted to the bracket so that the movable seat can move relative to the bracket in the front-back direction. The movable seat is provided with a guide groove that gradually slopes downward from front to back. The massage mechanism is installed on the front side of the movable seat. The lifting seat is movably fitted to the bracket so that the lifting seat can move relative to the bracket in the vertical direction. The lifting seat is provided with a movable block that slides and is embedded in the guide groove.

[0008] The drive mechanism is mounted on the bracket, and its output end is connected to the lifting seat to drive the lifting seat to move up and down relative to the bracket.

[0009] Preferably, the drive mechanism includes a motor and a transmission component. The central axis of the motor shaft is perpendicular to the front-to-back direction. One end of the transmission component is connected to the motor shaft, and the other end of the transmission component is connected to the lifting seat.

[0010] Preferably, the transmission component includes a housing, a worm gear pivotally connected to the housing, a worm wheel pivotally connected to the housing, a lead screw, and a nut; the housing is fixedly connected to the bracket, the worm gear is synchronously connected to the motor shaft, the worm wheel meshes with the worm gear, and the central axis of the worm wheel is aligned with the vertical direction, one end of the lead screw is synchronously connected to the worm wheel, and the nut is sleeved on the lead screw and fixedly engaged with the lifting seat.

[0011] Preferably, a guide rod extending vertically is provided on each side of the bracket, and the two sides of the lifting seat are slidably sleeved on the two guide rods.

[0012] Preferably, the movable seat includes an end wall and a side wall. The side wall extends forward from the periphery of the end wall to form a storage groove with a front opening through the side wall and the end wall. The massage mechanism is connected to the end wall and is housed in the storage groove. The massage head of the massage mechanism protrudes from the front opening of the storage groove.

[0013] Preferably, a guide groove is provided on each side of the sidewall, and a movable block is provided on each side of the lifting seat, with the two movable blocks slidably embedded in the two guide grooves.

[0014] Preferably, a connecting arm extending forward is provided on each side of the lifting seat, and the movable block includes a pivot extending inward from the front end of the connecting arm and a roller mounted on the pivot.

[0015] Preferably, the side wall of the movable seat is provided with an upper positioning groove and a lower positioning groove, the upper positioning groove extending upward from the upper end of the guide groove, and the lower positioning groove extending downward from the lower end of the guide groove.

[0016] Preferably, the side wall of the movable seat is provided with a plurality of guide posts extending in the front-to-back direction, the bracket is provided with a plurality of sliding grooves, the guide posts are embedded in the sliding grooves, and a wear-resistant bushing is provided between the guide posts and the inner wall surface of the sliding grooves.

[0017] Seats, including the aforementioned seat support components.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] In this invention, the movable block on the lifting seat cooperates with the inclined guide groove on the movable seat to link the movable seat and the lifting seat. When the drive mechanism drives the lifting seat to move up and down, the movable seat moves in the front and back direction, thereby driving the massage mechanism installed on the movable seat to move back and forth. Since the up and down movement of the lifting seat drives the front and back movement of the movable seat, the drive mechanism does not occupy a large space in the front and back direction while ensuring that the massage mechanism has a sufficient range of motion in the front and back direction. The space in the upper and lower direction inside the outer frame can be fully utilized, so that the entire support assembly has a relatively small size in the front and back direction, reducing the volume of the support assembly and facilitating the spatial layout of various components on the seat.

For example, they can refer to a fixed connection, a connection through an intermediary, or a connection within two elements or an interaction between two elements. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0029] like Figure 1 , 2 As shown in Figures 3, 4, and 5, this is the support component of the seat according to the present invention. Specifically, it is a headrest component for supporting the user's head and neck on a seat. It includes an outer frame 10, a bracket 20, a movable seat 30, a lifting seat 40, a drive mechanism 600, and a massage mechanism 50. A flexible support shield is provided on the front side of the outer frame 10. The flexible shield can be a flexible component such as mesh or shaping cotton that is suitable for contact with the user's head and neck. The flexible shield covers the front side of the outer frame 10. The outer frame 10 and the rear side of the flexible shield form an accommodating space. The bracket 20, movable seat 30, lifting seat 40, drive mechanism 600, and massage mechanism 50 are all located in this accommodating space.

[0030] The bracket 20 is fixedly engaged with the outer frame 10, which can be achieved by fixing the bracket 20 to the back plate 11 on the back of the outer frame 10. The movable seat 30 is located in front of the bracket 20 and is movably engaged with the bracket 20, allowing the movable seat 30 to move relative to the bracket 20 in the front-back direction. A guide groove 31 is provided on the movable seat 30, which gradually slopes downward from front to back. The massage mechanism 50 is installed in front of the movable seat 30. The lifting seat 40 is movably engaged with the bracket 20, allowing the lifting seat 40 to move in the vertical direction. For the movement of the support 20, the lifting seat 40 is provided with a movable block that slides and is embedded in the guide groove 31. The movable block cooperates with the guide groove 31 to link the up-and-down movement of the lifting seat 40 with the back-and-forth movement of the movable seat 30. When the lifting seat 40 moves from top to bottom, the movable block slides along the guide groove 31 and pushes the front side wall of the guide groove 31 forward, causing the movable seat 30 to move forward. When the lifting seat 40 moves from bottom to top, the movable block slides along the guide groove 31 and pushes the rear side wall of the guide groove 31 backward, causing the movable seat 30 to move backward.

[0031] The drive mechanism 600 is mounted on the bracket 20, and its output end is connected to the lifting seat 40 to drive the lifting seat 40 to move up and down relative to the bracket 20. That is, the drive mechanism 600 drives the lifting seat 40, so that the lifting seat 40 acts as the active component and the movable seat 30 acts as the driven component, and moves accordingly with the movement of the lifting seat 40.

[0032] It should be noted that the support component of this utility model can be a lumbar support component installed on a seat to support the user's waist, a backrest component installed on a seat to support the user's back, or a component used to support other parts of the user's body.

[0033] In this invention, the movable block on the lifting seat 40 cooperates with the inclined guide groove 31 on the movable seat 30 to link the movable seat 30 and the lifting seat 40. When the drive mechanism 600 drives the lifting seat 40 to move up and down, the movable seat 30 moves in the front and back direction, thereby driving the massage core 50 installed on the movable seat 30 to move back and forth. Since the movement of the movable seat 30 is driven by the up and down movement of the lifting seat 40, the massage core 50 is guaranteed to have sufficient range of motion in the front and back direction. This ensures that the drive mechanism 600 does not occupy a large space in the front and back direction, and can make full use of the space in the upper and lower direction inside the outer frame 10. This makes the entire support assembly relatively small in size in the front and back direction, reducing the volume of the support assembly and facilitating the spatial layout of various components on the seat.

[0034] In a preferred embodiment, the drive mechanism 600 includes a motor 60 and a transmission component 70. The central axis of the rotating shaft of the motor 60 is perpendicular to the front-to-back direction. One end of the transmission component 70 is connected to the rotating shaft of the motor 60, and the other end is connected to the lifting seat 40. The housing of the motor 60 is fixed on the bracket 20, and the power of the motor 60 is transmitted to the lifting seat 40 through the transmission component 70.

[0035] The transmission component 70 includes a housing 75, a worm 71, a worm wheel 72, a lead screw 73, and a nut 74. The worm 71 and the worm wheel 72 are both pivotally connected inside the housing 75, which is fixedly connected to the bracket 20. The worm 71 is synchronously connected to the rotating shaft of the motor 60. The worm wheel 72 meshes with the worm 71, and the central axis of the worm wheel 72 is aligned with the vertical direction. One end of the lead screw 73 is synchronously connected to the worm wheel 72. The nut 74 is sleeved on the lead screw 73 and fixed to the lifting seat 40.

[0036] The worm gear 72 and worm 71 of the transmission component 70 form a reduction mechanism. This reduction mechanism increases the torque, giving the lead screw 73 a relatively large torque. As the lead screw 73 rotates, the threads of the nut 74 meshing with the lead screw 73 cause the lifting seat 40 to move up and down. Since the central axis of the worm gear 72 is aligned with the vertical direction, and the central axis of the motor 60's shaft is perpendicular to the front-back direction, placing the motor 60 horizontally on the bracket 20 occupies less space in both the front-back and vertical directions, thus fully utilizing the lateral space inside the outer frame 10.

[0037] In order to ensure that the lifting seat 40 can move up and down smoothly and to avoid jamming or jamming during the linkage between the lifting seat 40 and the movable seat 30, a guide rod 44 extending up and down is provided on both sides of the bracket 20. A guide hole is provided on both sides of the lifting seat 40, and the two guide rods 44 are respectively inserted into the guide holes, so that the two sides of the lifting seat 40 are slidably sleeved on the two guide rods 44. The guide rods 44 guide the up and down movement of the lifting seat 40, so that the lifting seat 40 can move up and down smoothly.

[0038] The active seat 30 includes an end wall 301 and a side wall 302. The side wall 302 is located at the periphery of the end wall 301 and extends forward from the periphery of the end wall 301. The side wall 302 and the end wall 301 form a storage groove with a front opening. The massage mechanism 50 is connected to the end wall 301, so that the massage mechanism 50 is housed in the storage groove, thereby protecting the massage mechanism 50 and preventing the electronic components on the massage mechanism 50 from being damaged by collision. The massage head on the massage mechanism 50 protrudes from the front opening of the storage groove. The massage head can press against the flexible shield installed on the front of the outer frame 10 to massage the corresponding parts of the user's body.

[0039] A guide groove 31 is provided on each side of the side wall 302, and a movable block is provided on each side of the lifting seat 40. The two movable blocks are slidably embedded in the two guide grooves 31, so that the linkage between the lifting seat 40 and the movable seat 30 is more stable. A connecting arm 41 extending forward is provided on each side of the lifting seat 40. The two connecting arms 41 are located on both sides of the movable seat 30. The movable block includes a pivot 43 extending inward from the front end of the connecting arm 41 and a roller 42 mounted on the pivot 43. The roller 42 rolls and rubs against the front and rear side walls of the guide groove 31, reducing the friction between them, making the relative movement of the lifting seat 40 and the movable seat 30 smoother, and reducing power consumption.

[0040] The side wall 302 of the movable seat 30 is provided with an upper positioning groove 311 and a lower positioning groove 312. The upper positioning groove 311 extends upward from the upper end of the guide groove 31, and the lower positioning groove 312 extends downward from the lower end of the guide groove 31. See [reference needed] Figure 4 As shown, when the lifting seat 40 is in its highest position, the roller 42 is located in the upper positioning groove 311, and the movable seat 30 is in its rearmost position; see also Figure 5 As shown, when the lifting seat 40 is in the lowest position, the roller 42 is located in the lower positioning groove 312, and the movable seat 30 is located in the foremost position.

[0041] Multiple guide posts 32 extending in the front-rear direction are provided on the side wall 302 of the movable seat 30. Multiple sliding grooves 21 are provided on the bracket 20. The guide posts 32 are embedded in the sliding grooves 21. Wear-resistant bushings 22 are provided between the inner wall surface of the sliding groove 21 and the guide posts 32. The guide posts 32 cooperate with the sliding grooves 21 to guide the front-rear movement of the movable seat 30. The wear-resistant bushings 22 can reduce the wear of the movable seat 30 and the bracket 20, ensuring that the support components have a long service life.

[0042] The seat of this utility model includes the aforementioned seat support assembly. The other structures of the seat are the same as those in the prior art and will not be described in detail here.

[0043] 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.
