[0041] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0042] First, refer to Figure 1 and Figure 2 The vehicle seat 100 according to the second embodiment of the utility model is briefly described.

[0043] like Figure 1 and Figure 2 As shown, the vehicle seat 100 includes a backrest 60, a frame 20, a base 30 and an angle adjustment mechanism 10. The frame 20 is rotatably disposed on the upper side of the base 30. The backrest 60 is connected to the frame 20 to cooperate with the frame 20 and the base 30 to provide good support for the human body.

[0044] Reference below Figure 3-Figure 10 A vehicle seat 100 according to an embodiment of a first aspect of the present invention is described.

[0045] like Figure 3-Figure 10 As shown, the angle adjustment mechanism 10 according to the first embodiment of the utility model comprises: a driving mechanism 11 and a supporting mechanism 12. The driving mechanism 11 is configured to drive the frame 20 to rotate relative to the base 30 of the vehicle seat 100; the two ends of the supporting mechanism 12 are respectively adapted to be rotatably connected to the base 30 and the frame 20, and the supporting mechanism 12 is retractable and used to support the frame 20.

[0046] The present embodiment provides a driving mechanism 11, which is configured to drive the frame 20 to rotate relative to the seat. When the vehicle seat 100 is adjusted in angle, the driving mechanism 11 operates to rotate the frame 20 relative to the base 30, thereby changing the arrangement angle of the frame 20, thereby changing the posture of the person when sitting, so that the person can sit in the vehicle seat 100 in a zero-gravity posture, thereby well meeting the use requirements of the vehicle seat 100.

[0047] It can be understood that when the frame 20 rotates relative to the base 30, the angle between the frame 20 and the base 30 changes continuously, so that the angle between the support mechanism 12 connected to the frame 20 and the base 30 and the frame 20, as well as the angle between the support mechanism 12 and the base 30 change continuously. In this embodiment, the two ends of the support mechanism 12 are respectively connected to the base 30 and the frame 20 in a drivable manner, so that the support mechanism 12 can follow the rotation of the frame 20 well and change the angle between the frame 20 and the base 30, so that the support mechanism 12 can cooperate well with the rotation of the frame 20 and connect the support frame 20, so that the support mechanism 12 can cooperate with the base 30 to stably support the frame 20.

[0048] It can be understood that when the frame 20 rotates relative to the base 30, the distance between the frame 20 and the base 30 changes. In this embodiment, the support mechanism 12 is retractable, so that the support mechanism 12 can well cooperate with the change in the distance between the frame 20 and the base 30 through telescoping, and stably and reliably support the connection between the frame 20 and the base 30, so that the vehicle seat 100 can operate more stably and reliably during the angle adjustment process.

[0049] It can be understood that when the support mechanism 12 is extended and retracted following the rotation of the frame 20, the support mechanism 12 as a whole can be extended and retracted along its extension direction, so that the support mechanism 12 occupies less dynamic space in the vehicle seat 100, and the telescopic movement is relatively simple and stable, and the force can be stably transmitted between the frame 20 and the base 30, so that the support mechanism 12 supports the frame 20 more stably and reliably, and the support mechanism 12 occupies less space in the vehicle seat 100, making the vehicle seat 100 more convenient and easy to assemble.

[0050] In this embodiment, a driving mechanism 11 is provided to drive the frame 20 to rotate relative to the base 30, and a supporting mechanism 12 is provided to support the frame 20, which can well meet the angle adjustment requirements of the vehicle seat 100. The supporting mechanism 12 can cooperate with the driving mechanism 11 to well improve the overall structural strength and rigidity performance of the vehicle seat 100, so that the overall structure of the vehicle seat 100 is more stable, and the operation and use of the vehicle seat 100 is more stable and reliable.

[0051] According to the vehicle seat 100 of the embodiment of the utility model, a driving mechanism 11 is provided to drive the frame 20 to rotate relative to the base 30, and a supporting mechanism 12 is provided to support the frame 20, so that the overall structure of the vehicle seat 100 has better rigidity and strength performance, and the vehicle seat 100 is more stable and reliable when the angle is adjusted, thereby making the vehicle seat 100 more stable when in use.

[0052] In some embodiments of the present invention, Figure 3-Figure 5 As shown, the support mechanism 12 may include: a first mating piece and a second mating piece, the first mating piece and the second mating piece are telescopically connected, one of the first mating piece and the second mating piece is suitable for being rotatably connected to the base 30, and the other is suitable for being rotatably connected to the frame 20.

[0053] In this embodiment, the support mechanism 12 is provided with a first mating part and a second mating part, and the first mating part and the second mating part are telescopically connected. When the vehicle seat 100 adjusts its angle or height, the first mating part and the second mating part telescope to move one end of the first mating part connected to the base 30 or the frame 20 away from or close to one end of the second mating part connected to the frame 20 or the base 30, so that the support mechanism 12 can well cooperate with the changes in the angle and height of the frame 20 to stably and reliably support and structurally strengthen the frame 20, and to a certain extent, make the vehicle seat 100 operate more stably during the angle adjustment or height adjustment process.

[0054] The first matching piece can be connected to the frame 20, and the second matching piece can be connected to the base 30, and the first matching piece can also be connected to the base 30, and the second matching piece can be connected to the frame 20. The first matching piece and the second matching piece can both be rods, and the first matching piece and the second matching piece can also be set as a slide groove structure, and the first matching piece and the second matching piece can also be set as other retractable structures to meet the needs of the support mechanism 12 for retracting and supporting the frame 20 and structural reinforcement.

[0055] In one embodiment of the present invention, Figure 3-Figure 5 As shown, the first matching piece may have a first sliding channel, and at least a portion of the second matching piece may be slidably disposed in the first sliding channel.

[0056] In this embodiment, the first mating piece is configured to have a first sliding channel, and the second mating piece is slidably arranged in the first sliding channel. When the second mating piece slides in the first sliding channel relative to the first mating piece, the second mating piece can be partially or completely in the first sliding channel, and the second mating piece slides relative to the first mating piece along the first sliding channel, thereby well meeting the assembly needs of the first mating piece and the second mating piece being telescopically connected. The structure is simple, so that the first mating piece and the second mating piece can perform telescopic operations stably and well.

[0057] The first sliding channel may be a cylindrical sliding channel, or may be a groove-shaped sliding channel. The structural form of the first sliding channel may be correspondingly arranged according to the structural forms and sliding matching manner of the first mating piece and the second mating piece.

[0058] In some examples of the present invention, Figure 3-Figure 5 As shown, the first mating piece can be formed as a first slide rail 121, and the second mating piece can be formed as a second slide rail 122. The first slide rail 121 and the second slide rail 122 are slidably matched, and the end of the first slide rail 121 facing away from the second slide rail 122 is suitable for rotatable connection with the frame 20, and the end of the second slide rail 122 facing away from the first slide rail 121 is suitable for rotatable connection with the base 30.

[0059] In this embodiment, the first matching member is configured as a first slide rail 121 , and the first slide rail 121 may have a first slide channel, and the second slide rail 122 may be slidably disposed in the first slide channel.

[0060] In this embodiment, the first matching member is set as the first slide rail 121, and the second matching member is set as the second slide rail 122. The structure is simple, the matching is convenient and stable, so that the support mechanism 12 can stably match the rotation of the frame 20 to be extended and retracted, and play a stable and good supporting role for the frame 20. The first slide rail 121 is rotatably connected to the frame 20, and the second slide rail 122 is rotatably connected to the base 30, which can well meet the needs of the support mechanism 12 during operation, so that the support mechanism 12 can well follow the change of the angle between the frame 20 and the base 30 and rotate accordingly, so that the vehicle seat 100 can maintain a stable structural state when adjusting the angle, so that the vehicle seat 100 can operate more stably.

[0061] In one example of the present invention, reference Figure 5 As shown, the number of the supporting mechanisms 12 can be multiple, and the multiple supporting mechanisms 12 are arranged in a first direction (such as Figure 5 The left and right directions as shown) are arranged at intervals.

[0062] In this embodiment, a plurality of support mechanisms 12 are provided, and the plurality of support mechanisms 12 cooperate to support the frame 20, so that the strength and rigidity of the overall structure of the frame 20, the support mechanisms 12 and the base 30 are better, so that when the frame 20 rotates relative to the base 30, the plurality of support mechanisms 12 can more stably connect the frame 20 and the base 30 and better support the frame 20, so that the frame 20 can rotate more stably for angle adjustment, so that the vehicle seat 100 is more stable when performing angle adjustment operations. For example, the number of support mechanisms 12 can be two, three, four, five, six, etc., and the plurality of support mechanisms 12 are arranged at intervals in the first direction. The number of support mechanisms 12 can be reasonably set according to the needs of use. Preferably, two support mechanisms 12 are provided.

[0063] In one example of the present invention, Figure 5 and Figure 6 As shown, the driving mechanism 11 may include: a first driving member 111, a push rod 112 and a movable member 113, the first driving member 111 is arranged on the frame 20; one end of the push rod 112 is drivingly connected to the output shaft of the first driving member 111; the movable member 113 is connected to the second slide rail 122, and the movable member 113 is sleeved on the push rod 112 and spirally matched with the push rod 112.

[0064] In this embodiment, a first driving member 111, a push rod 112 and a movable member 113 are provided in the driving mechanism 11. The first driving member 111 is provided on the frame 20 so that the first driving member 111 can move with the frame 20. One end of the push rod 112 is drivingly connected to the output shaft of the first driving member 111. The movable member 113 is connected to the second slide rail 122 and is spirally matched with the push rod 112. When the driving mechanism 11 is running, the first driving member 111 drives the push rod 112 to rotate, so that the movable member 113 moves away from or close to the first driving member 111 along the extension direction of the push rod 112, so that the second slide rail 122 and the first slide rail 121 move telescopically, and then the part of the frame 20 where the first driving member 111 is fixed and the part of the base 30 where the second slide rail 122 is fixed move away from or close to each other, so that the angle between the frame 20 and the base 30 changes, and the frame 20 rotates relative to the base 30.

[0065] In this embodiment, a first driving member 111 is arranged to cooperate with a push rod 112 and a movable member 113, and the structure is simple. The first driving member 111 can stably and reliably drive the push rod 112 to operate, so that the push rod 112 cooperates with the movable member 113 to rotate the frame 20. The movable member 113 spirally cooperates with the push rod 112, and the torsional force of the first driving member 111 on the push rod 112 can be converted into a thrust for pushing the movable member 113 to move axially along the push rod 112, thereby meeting the use requirements of the driving mechanism 11, and the movable member 113 and the push rod 112 form a self-locking structure. After the frame 20 rotates into place, the first driving member 111 stops running, and the movable member 113 can be locked and fixed on the push rod 112, so that the angle between the frame 20 and the base 30 remains unchanged, so that the driving mechanism 11 can cooperate with the supporting mechanism 12 to stably support the frame 20.

[0066] In some specific embodiments of the present invention, Figure 6 As shown, the movable member 113 can be fixed to the connecting member 50. In this way, the movable member 113 can be connected to the second slide rail 122 through the connecting member 50, the structure is simple, and the connection and fixing are convenient. Since the connecting member 50 extends in the first direction, the movable member 113 is more flexible in arrangement, so that the driving mechanism 11 can be more flexibly arranged in the vehicle seat 100.

[0067] In some specific embodiments of the present invention, reference is made to Figure 6 and Fig.10 As shown, the number of the driving mechanism 11 may be at least one. When the number of the driving mechanism 11 is multiple, the multiple driving mechanisms 11 are arranged at intervals in the first direction.

[0068] In the present embodiment, the number of driving mechanisms 11 is set to at least one, which can meet the use requirements of the angle adjustment mechanism 10. When the number of driving mechanisms 11 is set to be multiple, multiple driving mechanisms 11 can cooperate to adjust the angle of the vehicle seat 100, so that the vehicle seat 100 is more stable and reliable when performing angle adjustment operations. Multiple driving mechanisms 11 can more stably and reliably lock the frame 20 and the base 30, so that the frame 20 and the base 30 can maintain the angle more stably and reliably, and the frame 20 can be better supported and fixed, so that the overall structural stability of the vehicle seat 100 is better.

[0069] In this embodiment, when the number of driving mechanisms 11 is multiple, refer to Fig.10 As shown, multiple driving mechanisms 11 are arranged at intervals in the first direction, so that during the angle adjustment process, the frame 20 and the base 30 can obtain a relatively stable and consistent thrust in the first direction, so that the driving mechanism 11 can more stably adjust the angle between the frame 20 and the base 30.

[0070] In this embodiment, when the number of the driving mechanisms 11 is multiple, the multiple first driving members 111 in the multiple driving mechanisms 11 can provide a greater driving force, thereby better meeting the need for angle adjustment of the vehicle seat 100. For example, the number of the driving mechanisms 11 can be one, two, three, four, etc., and the multiple driving mechanisms 11 can be arranged at intervals in the first direction.

[0071] In one example of the present invention, Figure 5 and Figure 7 As shown, the support mechanism 12 may further include: a first fixed frame 123 and a second fixed frame 124, the first fixed frame 123 is fixedly connected to the first slide rail 121, and the first fixed frame 123 is suitable for being rotatably connected to the frame 20; the second fixed frame 124 is fixedly connected to the second slide rail 122, and the second fixed frame 124 is suitable for being rotatably connected to the base 30.

[0072] In this embodiment, a first fixed frame 123 is rotatably connected to the frame 20 and fixedly connected to the first slide rail 121. The structure is simple, which facilitates the connection and assembly of the first slide rail 121 and the frame 20. The second fixed frame 124 is rotatably connected to the base and fixedly connected to the second slide rail 122. The structure is simple, which facilitates the connection and assembly of the second slide rail 122 and the base 30.

[0073] In this embodiment, the first fixing frame 123 and the second fixing frame 124 can play a role in structural reinforcement of the connection parts between the support mechanism 12 and the frame 20 and the base 30, so that the support mechanism 12 and the base 30 can have better structural strength and rigidity, so that the support mechanism 12 can better support the frame 20, and make the overall structure of the support mechanism 12 and the frame 20 and the base 30 more stable.
