Description

Technical Field

[0001] This invention relates to the field of automotive seat technology, and more particularly to a multifunctional automotive seat that integrates side sliding, rotation, and folding. Background Technology

[0002] Car seats are the core components in a car cabin that provide support, positioning, and comfort for drivers and passengers. They not only need to fix the bodies of drivers and passengers to ensure driving safety, but also play a core role in supporting driving operations and relieving fatigue on long journeys. They are a key assembly that affects the overall driving and riding experience.

[0003] Current car seats, especially front seats, are generally unable to fold flat due to limitations in functional integration and design, making it difficult to meet the needs of rear passengers for expanding their field of vision and providing leg support for a reclining position. Furthermore, while they can achieve a reclining position through leg rest and backrest adjustments, cabin space constraints prevent the integration of extended functions such as fully folding backrests, rotation, and side sliding. Even if current front seats do offer rotation functionality, the rotation mechanism is often located under a sliding rail, resulting in a relatively high seat cushion height, leading to insufficient seating space and reduced comfort.

[0004] Therefore, this application aims to provide a multi-functional car seat that integrates side-sliding, rotating, and folding, enabling multi-posture adjustments such as folding flat and rotating side-sliding. This not only expands the field of vision and provides reclining support for rear passengers but also allows for flexible adjustment of the cabin space layout. Furthermore, the overall seat structure has a low block value (low overall seat height), effectively avoiding the problem of excessively high seat cushions caused by existing integrated rotating structures, providing passengers with more comfortable space, and significantly improving the comfort of drivers and passengers as well as the utilization rate of cabin space.

By integrating front and rear slide rails, side slide rails, and a rotating disc, the seat can move flexibly and rotate in four directions (front, back, left, and right) within a plane. This allows the seat to be adjusted to the optimal position before activating the zero-gravity mode, solving the problem of insufficient front space preventing leg extension when activating zero-gravity adjustment in existing seats. This improves space utilization efficiency and meets the diverse spatial layout needs of drivers and passengers. Simultaneously, the coordinated operation of the front lifting motor, rear lifting motor, and lead screw motor enables the seat to fold, not only expanding the field of vision and providing reclining support for rear passengers but also providing more ample styling space for the backrest to fold down, significantly improving the utilization rate of cabin space. By placing the rotating disk assembly between the seat cushion frame assembly and the slide rail assembly, the space under the seat cushion frame assembly can be utilized to house all three motors of the slide rail assembly and the rotating disk assembly in the middle area under the seat. This reduces the overall height of the seat, effectively avoiding the problem of the seat cushion being too high due to the integrated rotating structure in existing seats, and creating a more comfortable and spacious riding environment for passengers with a lower block value (lower overall seat height).

[0032] Current car seats, especially front seats, are generally unable to fold flat due to limitations in functional integration and design, making it difficult to meet the needs of rear passengers for expanding their field of vision and providing leg support for a reclining position. Furthermore, while they can achieve a reclining position through leg rest and backrest adjustments, cabin space constraints prevent the integration of extended functions such as fully folding backrests, rotation, and side sliding. Even if current front seats do offer rotation functionality, the rotation mechanism is often located under a sliding rail, resulting in a relatively high seat cushion height, leading to insufficient seating space and reduced comfort.

[0033] To address the aforementioned issues, this application provides a multi-functional car seat that integrates side-sliding, rotating, and folding mechanisms. This allows for multi-positional adjustments, including folding flat, rotating, and side-sliding, providing rear passengers with expanded visibility, reclining support, and flexible cabin space layout. Furthermore, the seat's overall structure has a low block value (low overall seat height), effectively avoiding the high seat cushion issue caused by existing integrated rotating structures. This provides passengers with more comfortable space, significantly improving passenger comfort and cabin space utilization.

[0034] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0035] Example

[0036] Please see Figures 1-8 The multi-functional car seat with side-sliding, rotating, and folding design of this application includes a seat cushion frame assembly 1, a slide rail assembly 2, a rotating disc assembly 3, a backrest frame assembly 4, and a leg support assembly 5. The slide rail assembly 2 and the rotating disc assembly 3 are both located below the seat cushion frame assembly 1. The backrest frame assembly 4 and the leg support assembly 5 are respectively located on the rear and front sides of the seat cushion frame assembly 1 and are fixedly connected to the seat cushion frame assembly 1, respectively serving to support the back and legs of the user.

[0037] Specifically, the slide rail assembly 2 is located below the seat cushion frame assembly 1, and is used to drive the seat cushion frame assembly 1, the rotating disk assembly 3, and the backrest frame assembly 4 to move in four directions: forward, backward, left, and right. Figures 2-3 As shown, the slide rail assembly 2 includes a first slide rail assembly 21 and a second slide rail assembly 22. The first slide rail assembly 21 is disposed below the second slide rail assembly 22 and is fixedly connected to the second slide rail assembly 22 for realizing the forward and backward movement of the car seat. The second slide rail assembly 22 is connected to the rotary disk assembly 3 for realizing the left and right movement of the car seat. For example, the first slide rail assembly 21 and the second slide rail assembly 22 are generally H-shaped and their directions are perpendicular to each other. Specifically, both the first slide rail assembly 21 and the second slide rail assembly 22 include a slide rail drive motor 2a, a transmission assembly 2b, and a linear slide rail 2c. The slide rail drive motor 2a is mounted between the two linear slide rails 2c via a motor mounting bracket and is perpendicular to the linear slide rails 2c. The transmission assembly 2b is connected to both the slide rail drive motor 2a and the linear slide rails 2c, and is used to transmit the power of the slide rail drive motor 2a to the linear slide rails 2c. The linear slide rail 2c includes an upper rail and a lower rail, and the upper rail and the lower rail are slidable relative to each other. The transmission assembly 2b is fixedly connected to the upper rail and is used to drive the upper rail to move relative to the lower rail. When the driver or passenger needs to adjust the seat position forward or backward, the slide rail drive motor 2a in the first slide rail assembly 21 is activated, and the power is transmitted to the linear slide rail 2c through the transmission assembly 2b, causing the upper rail to slide relative to the lower rail, thereby moving the entire seat in the forward or backward direction to meet the needs of different drivers or passengers for the forward or backward position of the seat. When left and right adjustments are required, the slide rail drive motor 2a in the second slide rail assembly 22 starts, and transmits power to the linear slide rail 2c via the transmission assembly 2b. This causes the second slide rail assembly 22 to move the rotating disk assembly 3 and the entire seat in the left and right direction, facilitating the adjustment of the lateral position of the driver and passengers within the cabin. This ensures flexible movement of the seat within a planar range and optimizes space utilization. Furthermore, the upper rail of the first slide rail assembly 21 is provided with several mounting screw holes 211; the lower rail of the second slide rail assembly 22 is provided with mounting through holes corresponding to the mounting screw holes 211. A bolt assembly passes through the mounting screw holes 211 and the mounting through holes to fix the second slide rail assembly 22 onto the first slide rail assembly 21. The upper rail of the second slide rail assembly 22 is provided with studs 221, which are used to connect with the rotating disk assembly 3.

[0038] The rotating disk assembly 3 is disposed between the seat cushion frame assembly 1 and the slide rail assembly 2, with its upper end connected to the seat cushion frame assembly 1 and its lower end connected to the slide rail assembly 2. Specifically, the rotating disk assembly includes a first drive motor 31, a second drive motor 32, a first mounting bracket 33, a second mounting bracket 34, and a gear ring 35. The first mounting bracket 33 is connected to the slide rail assembly 2, meaning it has a screw hole adapted to the stud 221. By passing the stud 221 through the screw hole and locking it with a nut, the first mounting bracket 33 is fixed to the upper rail of the second slide rail assembly 22, providing stable support for the entire rotating disk assembly. The second mounting bracket 34 is disposed above the first mounting bracket 33 and is fixedly connected to the seat cushion frame assembly 1. Multi-point bolt connections smoothly transmit rotational power to the seat cushion frame assembly 1, ensuring stability during rotation. The gear ring 35 is mounted on the first mounting bracket 33 and located in the central area of ​​the first mounting bracket 33. The first drive motor 31 and the second drive motor 32 are fixed on the second mounting bracket 34, and the gears on the output ends of the first drive motor 31 and the second drive motor 32 are respectively meshed with the gear ring 35. When the seat needs to be rotated, the first drive motor 31 and the second drive motor 32 start simultaneously. Through the meshing transmission of the gears with the gear ring 35, the second mounting bracket 34 and the seat cushion frame assembly 1, backrest frame assembly 4 and leg support assembly 5, which are fixedly connected to the second mounting bracket 34, are driven to rotate around the central axis of the gear ring 35, realizing the rotation adjustment of the seat in the cabin. This allows the driver and passengers to change the sitting direction for communication or adjust their sitting posture for a better view.

[0039] The bottom end of the backrest frame assembly 4 is connected to the rear end of the seat cushion frame assembly 1. Specifically, the backrest frame assembly 4 includes a backrest frame 41, a backrest motor 42, a synchronizing rod 43, an adjuster 44, and a lower connecting plate 45. The backrest motor 42 is fixed on the backrest frame 41, and the output end of the backrest motor 42 is poweredly connected to the synchronizing rod 43. Both ends of the synchronizing rod 43 pass through the adjuster 44 and are engaged with the adjuster 44. The adjuster 44 and the lower connecting plate 45 are respectively disposed on both sides of the backrest frame 41, and the top end of the lower connecting plate 45 is welded and fixed to the adjuster 44 to form a rigid connection. The bottom end of the lower connecting plate 45 is provided with bolt mounting holes 451 for connecting with the seat cushion frame assembly 1. The bolt mounting holes 451 adopt a countersunk design to form a flat contact surface when connected with the seat cushion frame assembly 1, which ensures the connection strength and avoids the impact of protruding structures on the riding comfort. When the backrest motor 42 is started, the rotational power output by the backrest motor 42 is transmitted to the gear set inside the angle adjuster 44 via the synchronizing rod 43. The power is converted into the angle adjustment of the backrest frame 41 through gear meshing, thereby adjusting the angle of the chair back.

[0040] The seat cushion frame assembly 1 includes a fixed base plate 11, a seat cushion side plate 12, a front lifting motor 13, a rear lifting motor 14, a rear lifting link 15, and a front lifting link 16. The fixed base plate 11 is connected to the rotating disk assembly. For example, the fixed base plate 11 is provided with fixing screw holes, and the second mounting bracket 34 of the rotating disk assembly is provided with fixing through holes adapted to the fixing screw holes. The seat cushion frame assembly 1 is fixed to the rotating disk assembly by bolts passing through the fixing screw holes and the fixing through holes. The two ends of the seat cushion side plate 12 are respectively fixed to the fixed base plate 11, and the seat cushion side plate 12 is provided with welding nuts adapted to the bolt mounting holes 451 for connection with the backrest frame 41. The front lifting motor 13 is located on the inner front end of the seat cushion side plate 12 and is poweredly connected to the front lifting linkage 16. One end of the front lifting linkage 16 is hinged to the fixed base plate 11, and the other end is engaged with the shaft of the front lifting motor 13. When the front lifting motor 13 rotates forward, its shaft rotates, driving the front lifting linkage 16 to move. Since one end of the front lifting linkage 16 is hinged to the fixed base plate 11 and the other end is engaged with the shaft of the front lifting motor 13, the front end of the seat cushion side plate 12 will be lifted upward around the hinge point, realizing the function of lifting the front end of the seat and meeting the different sitting posture needs of the driver and passengers. Conversely, simply reversing the front lifting motor 13 will lower the front end of the seat. The rear lifting motor 14 is located on the inner rear end of the seat cushion side plate 12 and is poweredly connected to the rear lifting linkage 15. One end of the rear lifting linkage 15 is hinged to the fixed base plate 11, and the other end is fixed to the seat cushion side plate 12. When the rear lifting motor 14 rotates forward, its shaft rotates, driving the rear lifting linkage 15 to move. Because one end of the rear lifting linkage 15 is hinged to the fixed base plate 11 and the other end is fixed to the seat cushion side plate 12, the rear end of the seat cushion side plate 12 is lifted upward around the hinge point. Conversely, simply reversing the rear lifting motor 14 will lower the seat, providing a basis for the subsequent folding function.

[0041] Furthermore, to achieve the folding function, the seat cushion frame assembly 1 also includes a rear horizontal tube 17, a lead screw motor 18, a seat cushion lead screw bushing 19, and a seat cushion upper basin frame 110. Both ends of the rear horizontal tube 17 pass through the seat cushion side plate 12 and are fixedly connected to the rear lifting link 15, forming a stable force-bearing structure. The lead screw motor 18 is mounted on the seat cushion upper basin frame 110. One end of the seat cushion lead screw bushing 19 is threadedly connected to the lead screw motor 18, and the other end is hinged to the connecting bracket of the rear horizontal tube 17. When the lead screw motor 18 is started, its rotational motion drives the seat cushion lead screw bushing 19 to perform linear motion. Since the other end of the seat cushion lead screw bushing 19 is hinged to the connecting bracket of the rear horizontal tube 17, this linear motion is converted into a rotational motion of the rear horizontal tube 17 around its axis. The rotation of the rear horizontal tube 17 drives the rear lifting link 15 and the rear end of the seat cushion side plate 12, which are fixedly connected to it, to rotate around the hinge point, thereby raising or lowering the rear end of the seat. When the seat needs to be folded, the front lifting motor 13, the rear lifting motor 14, and the lead screw motor 18 work together. The front lifting motor 13 and the rear lifting motor 14 drive the upper lifting link 16 and the lower lifting link 15 to rotate downwards, so that the seat cushion reaches its lowest position. At the same time, the lead screw motor 18 drives the seat cushion upper frame 110 to rotate through the rear horizontal tube 17 past the highest point, and the height of the seat cushion upper frame 110 will decrease, leaving more space for the backrest to be fully flat. Then, the backrest motor 42 drives the backrest frame 41 to rotate forward to a horizontal angle (contact with the seat cushion's shaped surface) and then stops moving, thereby realizing the folding function of the seat and providing passengers with a more flexible and versatile way to use the seat.

[0042] It should be noted that the leg support assembly, the first track assembly, and other specific structures not described in detail are all existing technologies and will not be described in detail here.

[0043] Working principle:

[0044] When passengers need to adjust the seat position, they can move the seat forward, backward, left, and right by controlling the slide rail assembly 2. Specifically, for forward adjustment, the user simply presses the adjustment button to activate the slide rail drive motor 2a in the first slide rail assembly 21. The power is transmitted to the linear slide rail 2c via the transmission assembly 2b, causing the upper rail to slide relative to the lower rail, thereby moving the entire seat forward and backward. For left and right adjustment, the user simply activates the slide rail drive motor 2a in the second slide rail assembly 22. The transmission assembly 2b drives the upper rail of the linear slide rail 2c to move relative to the lower rail, causing the second slide rail assembly 22 to move the rotating disk assembly 3 and the entire seat left and right. When the seat direction needs to be rotated, the first drive motor 31 and the second drive motor 32 in the rotating disk assembly 3 are activated simultaneously. Through the meshing of the gear and the gear ring 35, the second mounting bracket 34 and the seat cushion frame assembly 1, backrest frame assembly 4, and leg support assembly, which are fixedly connected to the second mounting bracket 34, rotate around the central axis of the gear ring 35, realizing the rotation adjustment of the seat within the cabin. When the backrest angle needs to be adjusted, the backrest motor 42 is activated. The rotational power output by the motor is transmitted to the gear set inside the angle adjuster 44 via the synchronizing rod 43. Through gear meshing, the power is converted into angle adjustment of the backrest frame 41, thereby adjusting the seat back angle. When the seat folding function is required, the front lifting motor 13, the rear lifting motor 14, and the lead screw motor 18 work together. The front lifting motor 13 and the rear lifting motor 14 drive the upper lifting linkage 16 and the lower lifting linkage 15 to rotate downwards, bringing the seat cushion to its lowest position. At the same time, the lead screw motor 18 drives the upper seat cushion frame 110 to rotate through the rear cross tube 17, and then lowers its height after passing the highest point, leaving space for the backrest to be fully flattened. Then, the backrest motor 42 drives the backrest frame 41 to rotate forward to a horizontal angle and then stops moving, completing the seat folding.

[0045] In this embodiment, the multi-functional car seat with side-sliding, rotating, and folding design of this application includes a seat cushion frame assembly, a slide rail assembly, a rotating disc assembly, a backrest frame assembly, and a leg rest assembly. By integrating front and rear slide rails, side slide rails, and a rotating disc, the seat can move flexibly and rotate within a four-way plane, allowing it to be adjusted to the optimal position before activating zero-gravity mode. This solves the problem of insufficient front space preventing leg extension when activating zero-gravity adjustment in existing seats, improving space utilization efficiency and meeting the diverse spatial layout needs of drivers and passengers. Simultaneously, the coordinated operation of the front lifting motor, rear lifting motor, and lead screw motor enables the seat to fold, not only expanding the field of vision and providing reclining support for rear passengers but also providing more ample styling space for the backrest to fold down, significantly improving the utilization rate of cabin space. By placing the rotating disk assembly between the seat cushion frame assembly and the slide rail assembly, the space under the seat cushion frame assembly can be utilized to house all three motors of the slide rail assembly and the rotating disk assembly in the middle area under the seat. This reduces the overall height of the seat, effectively avoiding the problem of the seat cushion being too high due to the integrated rotating structure in existing seats, and creating a more comfortable and spacious riding environment for passengers with a lower block value (lower overall seat height).

[0046] In the description of this application, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is usually based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this application and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this application; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0047] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures.

Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0048] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
