Description

Technical Field

[0001] This invention relates to the field of automotive seat technology, and more particularly to a multifunctional zero-gravity automotive seat that can be converted into a bed with a single click. Background Technology

[0002] Zero-gravity seats are ergonomically designed seats that use a specific mechanism to adjust the backrest and leg rest to distribute body weight evenly across the seat surface. This effectively counteracts the pressure of gravity on the spine, pelvis, and other parts of the body, simulating the comfort of a person in a weightless environment like in space. They are particularly effective in reducing fatigue during long journeys and are now widely used in the automotive industry.

[0003] Current zero-gravity car seats lack effective support for the hands, shoulders, and head, leading to discomfort in these areas during long journeys. Secondly, adjusting the backrest angle uniformly raises the seat cushion, resulting in an excessively high cushion that compromises comfort. Furthermore, limitations in the functional structure and discrepancies between the seat cushion and backrest prevent current zero-gravity seats from fully reclining into a bed, failing to provide a flat and comfortable resting space.

[0004] Therefore, this application aims to provide a multi-functional zero-gravity car seat that can be converted into a bed with a single touch, providing effective support for the occupant's hands, shoulders, and head, thus avoiding discomfort caused by prolonged sitting. Simultaneously, it can raise the seat cushion differently based on the adjustment of the backrest angle, eliminating the difference in height between the seat cushion and backrest, providing users with a flat and comfortable resting space, and ensuring seating comfort. In addition, it innovatively integrates multiple functions such as a long sliding rail assembly, side sliding rail assembly, rotating disc assembly, leg rest assembly, lifting armrests, side wing assembly, and four-way headrest, and can seamlessly switch between multiple modes such as one-touch zero gravity, one-touch bed conversion, and welcome mode, meeting the diverse needs of users in different scenarios and greatly improving the practicality and versatility of the seat.

[0016] The technical solution provided in this application has the following beneficial effects:

[0017] (1) The multi-functional zero-gravity car seat of this application, which can be converted into a bed with one click, includes a seat cushion frame assembly, a backrest frame assembly, an armrest assembly, a headrest assembly, a side wing assembly, a leg rest assembly, a long slide rail assembly, a side slide rail assembly, and a rotating disc assembly. By innovatively integrating the adjustable structures such as the armrest assembly, the headrest assembly, the side wing assembly, and the leg rest assembly into the zero-gravity seat, it can be personalized according to the occupant's body shape and sitting habits, ensuring that each occupant can obtain the best support effect and sitting experience. For example, by setting up height-adjustable armrest components, more comfortable hand support can be provided for passengers according to their needs; by setting the height and fore-and-aft position of the headrest components to be adjustable, the head curves of passengers of different heights can be precisely fitted; by setting the side wing components to be able to rotate inward or outward, stable lateral support can be provided for the shoulders, preventing the body from swaying when the vehicle turns or bumps; by setting the flip and telescopic functions of the leg rest components, comfortable support can be provided for the legs, effectively distributing body weight, relieving fatigue from long-term sitting, and providing a structural basis for subsequent one-click bed conversion.

[0018] (2) By setting up components such as an upper side plate, a lower side plate, a first backrest adjustment motor, and a second backrest adjustment motor, flexible adjustment of the backrest at small and large angles is achieved. The upper side plate can be driven to rotate via the first backrest adjustment motor, enabling small-angle backrest adjustment while effectively avoiding the problem of existing seats raising the seat cushion and compromising comfort when adjusting the backrest. When large-angle adjustment, zero-gravity adjustment, or bed-like adjustment is required, the lower side plate is driven to rotate via the second backrest adjustment motor, thereby moving the backrest linkage, linkage rotating plate, seat basin linkage, and seat basin frame. This effectively solves the problem of a step difference at the transition between the seat cushion and backrest in zero-gravity or lying-flat states, making the seat transition smoother and more natural, further improving overall comfort.

[0019] (3) By driving each functional component by motor, not only is the complexity of the seat frame reduced and the assembly difficulty lowered, but the controller can also realize the collaborative work and precise control between the components, thereby realizing the flexible conversion of the seat from the normal state to the zero gravity state and even the one-click bed state, and can truly realize the bed state, effectively meeting the diverse needs of users in different scenarios, and greatly improving the practicality and multifunctionality of the seat.

[0037] Current zero-gravity car seats lack effective support for the hands, shoulders, and head, leading to discomfort in these areas during long journeys. Secondly, adjusting the backrest angle uniformly raises the seat cushion, resulting in an excessively high cushion that compromises comfort. Furthermore, limitations in the functional structure and discrepancies between the seat cushion and backrest prevent current zero-gravity seats from fully reclining into a bed, failing to provide a flat and comfortable resting space.

[0038] To address the aforementioned issues, this application provides a multi-functional zero-gravity car seat that can be converted into a bed with a single touch. This seat provides effective support for the occupant's hands, shoulders, and head, preventing discomfort from prolonged sitting. Simultaneously, the seat cushion can be raised differently based on the backrest angle, eliminating the difference in height between the seat cushion and backrest, providing a flat and comfortable resting space and ensuring a comfortable ride. Furthermore, it innovatively integrates multiple functions such as a long sliding rail assembly, side sliding rail assembly, rotating disc assembly, leg rest assembly, lifting armrests, side wing assembly, and four-way headrest. It can seamlessly switch between multiple modes, including one-touch zero-gravity, one-touch bed conversion, and welcome mode, meeting diverse user needs in different scenarios and greatly enhancing the seat's practicality and versatility.

[0039] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0040] Example

[0041] Please see Figures 1-10This application discloses a multi-functional zero-gravity car seat that can be converted into a bed with a single click, comprising a seat cushion frame assembly 1, a backrest frame assembly 2, an armrest assembly 3, a headrest assembly 4, a side wing assembly 5, a leg rest assembly 6, a long slide rail assembly 7, a side slide rail assembly 8, and a rotating disc assembly 9. The backrest frame assembly 2 is located at the rear end of the seat cushion frame assembly 1 and is connected to it, allowing for adjustment of the backrest angle according to different user needs, providing comfortable back support for the occupant. The armrest assembly 3 is height-adjustable on both sides of the seat cushion frame assembly 1 and is fixedly connected to it, providing support for the hands and effectively reducing hand fatigue. The headrest assembly 4 is located at the top of the backrest frame assembly 2 and can move forward and backward and up and down relative to the seat cushion frame assembly 1, meaning the headrest assembly 4 has a four-way adjustment function, precisely conforming to the curves of the occupant's head and neck, providing all-around head support, and reducing the impact on the head caused by bumps during vehicle travel. The side wing assembly 5 is rotatably mounted on both sides of the backrest frame assembly 2 and connected to the backrest frame assembly 2. It is used to adjust according to the occupant's body shape and seating needs, providing stable support for the shoulders and preventing the occupant's body from swaying when the vehicle turns or bumps. The leg support assembly 6 is located on the front side of the seat cushion frame assembly 1 and is fixedly connected to the seat cushion frame assembly 1. It can flip and extend relative to the seat cushion frame assembly 1, that is, the leg support assembly 6 can extend and retract, providing comfortable support for the legs, further distributing body weight, and relieving leg pressure. The long slide rail assembly 7 is located below the seat cushion frame assembly 1 and is used to move the seat forward and backward. The side slide rail assembly 8 is located at the top of the long slide rail assembly 7 and is fixedly connected to it, used to move the seat left and right. Specifically, the side slide rail assembly 8 is located above the long slide rail assembly 7, and its direction of movement is perpendicular to that of the long slide rail assembly 7. This allows occupants to adjust the seat position according to their needs, achieving an optimal position and facilitating subsequent implementation of zero-gravity and bed-like functions. The rotating disc assembly 9 is located between the side slide rail assembly 8 and the seat cushion frame assembly 1, and is fixedly connected to both. It drives the seat to rotate, facilitating occupants getting in and out of the vehicle and interacting with rear passengers. Through the coordinated operation of these components, diverse user needs in different scenarios are met, greatly enhancing the practicality and multifunctionality of the seat. It should be noted that the specific structures of the long slide rail assembly 7, the side slide rail assembly 8, and the rotary disk assembly 9 are existing technologies and will not be described in detail here.

[0042] Specifically, the armrest assembly 3 includes an armrest mounting bracket 31, an armrest motor mounting bracket 32, an armrest screw motor 33, an armrest slider 34, an armrest slide rail 35, and an armrest panel 36. The armrest mounting bracket 31 is fixed to the seat cushion frame assembly 1 and located on both sides of the seat cushion frame assembly 1, providing a stable mounting base for the entire armrest assembly 3. The armrest motor mounting bracket 32 ​​is fixed to the bottom end of the armrest mounting bracket 31 by screws and is used to mount the armrest screw motor 33. The armrest screw motor 33 is mounted on the armrest motor mounting bracket 32, and the output end of the armrest screw motor 33 is poweredly connected to the armrest slider 34. For example, the output end of the armrest screw motor 33 is an armrest screw, which is arranged vertically, and the armrest slider 34 is sleeved on the armrest screw and threadedly connected to the armrest screw. When the handrail screw motor 33 is started, it drives the handrail slider 34 to move up and down along the extension direction of the screw. The inner rail 351 of the handrail slide rail 35 is fixedly connected to the handrail mounting bracket 31, and the outer rail 352 is slidably disposed on the inner rail 351 and connected to the handrail slider 34. The handrail panel 36 is disposed at the top of the outer rail 352 and fixedly connected to the outer rail 352, providing support for the user's hands. Thus, the handrail slider 34 drives the outer rail 352 to move up and down relative to the inner rail 351, thereby driving the handrail panel 36 to move up and down, providing just the right support for the occupant's hands and effectively reducing hand fatigue.

[0043] The headrest assembly 4 includes a headrest rod 41, a headrest rod connecting rod 42, a headrest slider 43, a first headrest motor 44, a second headrest motor 45, and a headrest front-to-back adjustment bracket 46. Two headrest rods 41 are provided, each vertically inserted into the headrest guide sleeve of the backrest frame assembly 2 and located at the top of the backrest frame assembly 2, providing stable support for the headrest assembly 4. The headrest rod connecting rod 42 is located at the top of the headrest rod 41 and is fixedly connected to it, thereby connecting the two headrest rods 41 and facilitating subsequent installation of the headrest cover. The headrest slider 43 is sleeved on the headrest rod 41. The first headrest motor 44 is fixedly connected to both the headrest slider 43 and the headrest rod connecting rod 42, and is used to drive the headrest assembly 4 to move up and down. For example, the headrest motor of the first headrest motor 44 is fixedly mounted on the headrest slider 43, and the headrest lead screw of the first headrest motor 44 is vertically arranged, with one end connected to the output end of the headrest motor and the other end threadedly connected to the headrest rod connecting rod 42. The headrest front-to-back adjustment bracket 46 is slidably mounted on the headrest slider 43. The second headrest motor 45 is connected to both the headrest front-to-back adjustment bracket 46 and the headrest slider 43, and is perpendicular to the first headrest motor 44, used to change the horizontal position of the headrest. For example, the drive motor of the second headrest motor 45 is fixed to the headrest front-to-back adjustment bracket 46 by screws, and the transmission lead screw of the second headrest motor 45 passes through the headrest slider 43 and is threadedly connected to the headrest slider 43.

[0044] When the headrest assembly 4 needs to be adjusted in height, the first headrest motor 44 is started. The headrest lead screw of the first headrest motor 44 rotates. Since the headrest lead screw is threadedly connected to the headrest rod connecting rod 42, and the headrest rod 41 can move up and down relative to the headrest slider 43, it will drive the headrest rod connecting rod 42 and the entire headrest assembly 4 to move up and down along the extension direction of the headrest rod 41, thereby realizing the adjustment of the height of the headrest assembly 4 and meeting the head support height needs of passengers of different heights. When the headrest assembly 4 needs to be adjusted forward and backward, the second headrest motor 45 is activated. The transmission screw of the second headrest motor 45 rotates. Since the transmission screw is threadedly connected to the headrest slider 43, and the headrest forward and backward adjustment bracket 46 is slidably mounted on the headrest slider 43, when the transmission screw rotates, it can drive the headrest forward and backward adjustment bracket 46 to move forward and backward relative to the headrest slider 43, thereby realizing the forward and backward movement of the headrest assembly 4. This allows the headrest to accurately conform to the curve of the passenger's head and neck, providing all-round support for the head. During vehicle travel, it reduces the impact on the head caused by bumps and effectively improves the comfort of riding.

[0045] The side wing assembly 5 includes a side wing motor mounting bracket 51, a side wing lead screw motor 52, a side wing slider 53, a pivot limit bracket 54, a side wing pivot 55, and a side wing support frame 56. The side wing motor mounting bracket 51 is fixed to the side of the backrest frame assembly 2, providing a stable mounting base for the side wing lead screw motor 52. Preferably, the side wing motor mounting bracket 51 has a mounting section and a connecting section. The mounting section is used to mount the side wing lead screw motor 52 and the side wing slider 53, and the connecting section is generally arc-shaped to enable the side wing assembly 5 to rotate inward or outward. The side wing lead screw motor 52 is mounted on the side wing motor mounting bracket 51, and its output end is poweredly connected to the side wing slider 53 to drive the side wing slider 53 to perform linear motion. For example, the output end of the side wing screw motor 52 is a side wing screw, and the side wing slider 53 is sleeved on the side wing screw and threadedly connected to it. When the side wing screw motor 52 is started, it can drive the side wing slider 53 to move along the extension direction of the side wing screw. Further, the side wing slider 53 is fixed to the side wing motor mounting bracket 51 by bolts, so that the side wing motor mounting bracket 51 can move synchronously with the side wing slider 53. One end of the pivot limiting bracket 54 is fixed to the front flange of the backrest frame assembly 2 by bolts, and the other end is provided with a pivot ring. The side wing pivot 55 is rotatably disposed within the pivot ring, and one end is connected to the side wing motor mounting bracket 51, and the other end is fixedly connected to the side wing support frame 56. The side wing support frame 56 is provided with foam and a cover to provide more comfortable support for the shoulders.

[0046] When the position of the side wing assembly 5 needs to be adjusted, the side wing screw motor 52 is started, and the side wing screw of the side wing screw motor 52 rotates. Since the side wing slider 53 is sleeved on the side wing screw and threadedly connected to the side wing screw, and the side wing slider 53 is fixed to the side wing motor mounting bracket 51 by bolts, the rotation of the side wing screw will drive the side wing motor mounting bracket 51 to move along the extension direction of the side wing screw. The side wing pivot 55 is rotatably mounted within the pivot ring of the pivot limiting bracket 54, with one end connected to the side wing motor mounting bracket 51 and the other end fixedly connected to the side wing support frame 56. Therefore, when the side wing motor mounting bracket 51 moves, it will drive the side wing pivot 55 to rotate within the pivot ring, thereby driving the side wing support frame 56 to rotate, realizing the inward or outward rotation of the side wing assembly 5. This allows for adjustment according to the occupant's body shape and seating needs, providing stable support for the shoulders and preventing the occupant's body from swaying when the vehicle turns or bumps, effectively improving the safety and comfort of the ride.

[0047] Furthermore, to address the issue that adjusting the backrest angle of existing seats causes the seat cushion to rise, the backrest frame assembly 2 includes a lower side plate 21, an upper side plate 22, a first angle adjuster 23, and a first backrest adjustment motor 24. The lower side plate 21 is rotatably mounted on both rear side surfaces of the seat cushion frame assembly 1, and a limiting groove is provided on the lower side plate 21. The upper side plate 22 is rotatably mounted on the upper end of the lower side plate 21, and a limiting piece is provided on the upper side plate 22. The limiting piece passes through the limiting groove and can move within the limiting groove as the upper side plate 22 rotates. The first angle adjuster 23 is respectively mounted on the upper side plate 22 and is used to adjust the angle of the upper side plate 22. The first backrest adjustment motor 24 is mounted on the upper side plate 22, and the backrest lead screw of the first backrest adjustment motor 24 passes through the first angle adjuster 23 to drive the first angle adjuster 23 to rotate. When the backrest angle is adjusted, the first backrest adjustment motor 24 is first started. The backrest screw of the first backrest adjustment motor 24 rotates, driving the first angle adjuster 23 to rotate. Since the upper side plate 22 is connected to the first angle adjuster 23, the upper side plate 22 is driven to rotate accordingly. At this time, the limiting piece on the upper side plate 22 is restricted to move within the limiting groove. Therefore, when the angle is changed by the upper side plate 22 of the backrest frame assembly 2, only a small angle adjustment can be made, thereby providing a small angle of comfortable support for the occupant's back and meeting the occupant's need for slight adjustment of sitting posture. During this process, the seat cushion will not be raised.

[0048] Furthermore, in order to achieve large backrest tilt adjustment, the backrest frame assembly 2 also includes a second angle adjuster 25 and a second backrest adjustment motor 26; the second angle adjuster 25 is disposed at the bottom end of the lower side plate 21; the second backrest adjustment motor 26 is disposed on the lower side plate 21, and the lead screw of the second backrest adjustment motor 26 passes through the second angle adjuster 25 to drive the lower side plate 21 to rotate relative to the seat cushion frame assembly 1. When the limiting plate abuts against the front and rear walls of the limiting groove, the upper side plate 22 can no longer rotate relative to the lower side plate 21. Therefore, when the occupant continues to activate the seat back adjustment button, the second backrest adjustment motor 26 will be activated, causing the lead screw of the second backrest adjustment motor 26 to rotate, driving the second angle adjuster 25 to rotate. Since the lower side plate 21 is connected to the second angle adjuster 25, the lower side plate 21 will rotate relative to the seat cushion frame assembly 1, realizing the adjustment of the backrest at a large angle. This meets the occupant's need for a wider range of backrest angles when resting, allowing the occupant to rest in a more comfortable posture. Through the design of the above structure, the problem of seat cushion rising during backrest adjustment is cleverly solved, while taking into account both small angle and large angle adjustment needs, greatly improving the adjustment flexibility and riding comfort of the seat.

[0049] like Figures 8-9 As shown, the seat cushion frame assembly 1 includes a fixed base plate 11, a large side plate 12, a front lifting part 13, and a rear lifting part 14. The large side plate 12 is disposed at both ends of the fixed base plate 11 and is fixedly connected to the fixed base plate 11. The front lifting part 13 is disposed at the front end of the large side plate 12 and is used to drive the front end of the seat cushion to move up and down. The rear lifting part 14 is disposed at the rear end of the large side plate 12 and is used to drive the rear end of the seat cushion to move up and down. It should be noted that the specific structures of the front lifting part 13 and the rear lifting part 14 are existing technologies and will not be described in detail here.

[0050] Furthermore, to address the issue of the transition gap between the seat cushion and backrest when the existing seat is in a zero-gravity or reclining state, the seat cushion frame assembly 1 further includes a backrest connecting rod 15, a connecting rod rotating plate 16, a seat basin connecting rod 17, and a seat basin frame 18. One end of the backrest connecting rod 15 is fixed to the bottom end of the lower side plate 21, and the other end is fixedly connected to the connecting rod rotating plate 16. The connecting rod rotating plate 16 is rotatably mounted on the rear side plate of the seat cushion frame assembly 1. The seat basin connecting rod 17 is generally arc-shaped, and one end of the seat basin connecting rod 17 is movably riveted to the connecting rod rotating plate 16, while the other end is movably riveted to one end of the seat basin frame 18. The other end of the seat basin frame 18 is fixed to the large side plate 12.

[0051] When the backrest is adjusted to a large tilt angle, the bottom end of the lower side plate 21 moves forward, thereby driving the backrest connecting rod 15 to move forward. Since the backrest connecting rod 15 is fixedly connected to the connecting rod rotating plate 16, and the connecting rod rotating plate 16 is rotatably mounted on the rear side plate of the seat cushion frame assembly 1, the forward movement of the backrest connecting rod 15 will drive the connecting rod rotating plate 16 to rotate, thereby driving the seat basin connecting rod 17, which is movably riveted to the connecting rod rotating plate 16, to move upward, and thus driving the seat basin frame 18, which is movably riveted to the seat basin connecting rod 17, to move, causing the seat basin frame 18 to lift upward. Therefore, during the large tilt angle adjustment of the backrest, the seat basin frame 18 will rise accordingly with the large tilt angle adjustment of the backrest, making the transition between the seat cushion and the backrest smoother, effectively solving the problem of the step difference between the seat cushion and the backrest in zero gravity state or lying flat state, and further improving the comfort of the seat.

[0052] The leg support assembly 6 includes a leg support mounting bracket, a leg support flipping motor, a leg support telescopic motor, a leg support flipping link, a leg support telescopic link, and a leg support panel. The leg support mounting bracket is fixed to the front end of the seat cushion frame assembly 1 and welded to it, providing fixed support for the leg support assembly 6. The leg support flipping motor is mounted on the leg support mounting bracket, and its output end is poweredly connected to the leg support flipping link. One end of the leg support flipping link is connected to the output end of the leg support flipping motor, and the other end is connected to the leg support panel. When the leg support flipping motor is started, it drives the leg support flipping link to rotate, thereby causing the leg support panel to flip. The leg support telescopic motor is mounted on the leg support mounting bracket, and its output end is poweredly connected to the leg support telescopic link. One end of the leg support telescopic link is connected to the output end of the leg support telescopic motor, and the other end is connected to the leg support panel. When the leg support telescopic motor is started, it drives the leg support telescopic link to extend or retract, thereby causing the leg support panel to extend or retract. The leg support assembly 6 can extend and retract through its flipping and telescopic functions, providing comfortable support for the legs, further distributing body weight, and relieving leg pressure. It should be noted that the specific configuration of components such as the leg support flipping linkage and the leg support telescopic linkage in the support assembly is existing technology and will not be detailed here.

[0053] One-click bed making working principle:

[0054] When the seat needs to be converted into a bed with a single button press, pressing the button first activates the starter motors in the long slide rail assembly 7 and the side slide rail assembly 8, driving the seat to move forward, backward, left, and right to reach the optimal position (the maximum space the seat can extend). Then, the second backrest adjustment motor 26 in the backrest frame assembly 2 is activated. The lead screw of the second backrest adjustment motor 26 rotates, causing the second angle adjuster 25 to rotate, thereby causing the lower side plate 21 to rotate relative to the seat cushion frame assembly 1, achieving a large backrest tilt adjustment to a near-horizontal state. At the same time, during the backrest adjustment process, the backrest connecting rod 15 moves forward with the lower side plate 21, driving the connecting rod rotating plate 16 to rotate, causing the seat basin connecting rod 17 to move upward, thereby pushing the seat basin frame 18 to rise, keeping the transition between the seat cushion and the backrest smooth and without any steps. When the backrest is nearly horizontal, the leg support assembly 6 automatically activates. The leg support flipping motor drives the leg support flipping linkage to flip the leg support panel upwards to near horizontal position. Then, the leg support telescopic motor drives the leg support telescopic linkage to extend, extending the leg support panel forward to increase the leg support support length. During this process, the armrest panel 36 descends to its lowest position via the armrest slider 34 (i.e., basically at the same level as the upper plane of the seat cushion), providing more spacious lateral space for the bed-like configuration. Simultaneously, the side wing screw motor 52 in the side wing assembly 5 activates, driving the side wing support frame 56 to rotate outwards, causing the side wing shape to unfold, thereby achieving the effect of the entire backrest lying flat. Ultimately, the seat is completely transformed into a flat bed (i.e., the leg support panel, seat cushion, armrest panel, and backrest are almost at the same plane height), providing a comfortable resting space for the occupant. When it is necessary to restore the seat to its normal state, the motors operate in reverse order, retracting the leg support, raising the backrest, and adjusting the position of the seat cushion and armrests in sequence, quickly restoring the seat to its normal configuration. In addition, passengers can adjust the position of the headrest assembly 4 individually according to their actual needs to adapt to the head support requirements in different states.

[0055] It should be noted that the specific adjustment principles of the armrest assembly 3, the headrest assembly 4, and the side wing assembly 5 are detailed above and will not be repeated here.

[0056] In this embodiment, the multifunctional zero-gravity car seat that can be converted into a bed with a single click includes a seat cushion frame assembly, a backrest frame assembly, an armrest assembly, a headrest assembly, a side wing assembly, a leg rest assembly, a long slide rail assembly, a side slide rail assembly, and a rotating disc assembly. By innovatively integrating the adjustable structures such as the armrest assembly, the headrest assembly, the side wing assembly, and the leg rest assembly into the zero-gravity seat, personalized adjustments can be made according to the occupant's body shape and sitting habits, ensuring that each occupant receives optimal support and a comfortable riding experience. For example, by incorporating height-adjustable armrest components, more comfortable hand support can be provided to passengers according to their needs; by making the height and fore-and-aft position of the headrest components adjustable, it can precisely fit the head curves of passengers of different heights; by enabling the side wing components to rotate inward or outward, it can provide stable lateral support for the shoulders, preventing body swaying when the vehicle turns or bumps; by incorporating the flipping and telescopic functions of the leg rest components, it can provide comfortable support for the legs, effectively distributing body weight and alleviating fatigue from long-term sitting, providing a structural basis for subsequent one-click bed-like adjustments. By incorporating components such as the upper side panel, lower side panel, first backrest adjustment motor, and second backrest adjustment motor, flexible adjustment of the backrest angle, both small and large, is achieved. Furthermore, the first backrest adjustment motor can drive the upper side panel to rotate, enabling small-angle backrest adjustment while effectively avoiding the problem of existing seats raising the seat cushion and compromising comfort when adjusting the backrest. When large tilt angle adjustments, zero gravity adjustments, or bed-like configurations are required, the second backrest adjustment motor drives the lower side panel to rotate, thereby moving the backrest linkage, linkage rotating plate, seat basin linkage, and seat basin frame. This effectively solves the problem of a step difference at the transition between the seat cushion and backrest in zero gravity or reclining positions, making the seat's transformation process smoother and more natural, further enhancing overall comfort. By driving each functional component with a motor, the complexity of the seat frame is reduced, and the assembly difficulty is lowered. Furthermore, the controller enables coordinated and precise control between components, allowing for flexible transitions from a regular state to a zero gravity state and even a one-button bed-like configuration. This truly achieves the bed-like configuration, effectively meeting the diverse needs of users in different scenarios and greatly enhancing the seat's practicality and versatility.
