Description

Technical Field

[0001] This invention relates to the field of automotive seat technology, specifically to a universal posture adjustment module and a universal flexible seat with the module. Background Technology

[0002] Vehicle seats are the primary support structure for drivers and passengers, and their posture adjustment capabilities directly determine the comfort and safety of the driving experience. Currently, passenger vehicles are constantly upgrading their comfort and intelligent features, leading users to demand higher levels of seat adjustment functionality and adaptability to various scenarios. Traditional vehicle seats only offer basic adjustment functions such as fore-and-aft sliding, overall height adjustment, and backrest angle rotation, limiting the degree of freedom in adjustment.

[0003] In actual driving and riding, there are various posture requirements. For example, when the vehicle is parked and resting, the front of the seat cushion needs to be raised separately to create a zero-gravity support posture and improve rest comfort; during daily driving, the overall seat height needs to be adjustable to accommodate the operating vision and sitting posture of drivers and passengers of different heights; and when the vehicle is turning, lateral centrifugal force is generated, which can easily cause the driver and passengers to shift or slide to the side, reducing the riding experience.

[0004] In existing technologies, vehicle seats can only achieve a single adjustment mode, and cannot simultaneously meet multiple usage conditions such as zero-gravity posture adjustment, daily seat height adjustment, and balance compensation for driving and turning posture. Traditional seat adjustment mechanisms have a fixed structure and low degree of freedom in posture adjustment, and cannot achieve flexible omnidirectional posture adjustment of the seat frame relative to the vehicle body rails, resulting in poor adaptability to various scenarios. Summary of the Invention

[0005] In view of this, one of the objectives of the present invention is to provide a universal posture adjustment module that can realize multi-degree-of-freedom universal posture adjustment of the seat and meet the adaptive posture adjustment needs of the vehicle in various scenarios.

[0006] To achieve the above objectives, the technical solution of the present invention is as follows:

[0007] A universal posture adjustment module, the key feature of which is that it includes a base, on which at least three sets of adjustment units are provided, each set of adjustment units is equipped with a pusher component that can move along the height direction, the pusher component being used to connect to the bottom of the seat.

[0008] With the above structure, the pushing components of each adjustment unit can move independently or in coordination to lift and lower, enabling functions such as lifting the front and rear of the seat, adjusting the overall height, tilting to the left, and tilting to the right.

[0009] Preferably, the number of adjustment units is three sets, with two sets symmetrically arranged at the rear end of the base and the other set arranged in the central area of ​​the front end of the base. When applied to a seat, this structure creates a symmetrical left-right distribution, resulting in high stress balance. Simultaneously, the three support points of the three sets of pushing components can define a support plane. Through the coordinated operation of the three adjustment units, the seat frame can be adjusted to any spatial angle, including left or right tilt. This allows the device to achieve tilting, lateral tilting, and lifting adjustments of the seat in space with a minimal number of adjustment units, offering advantages such as refined structure, simple control, and low manufacturing and maintenance costs.

[0010] Preferably, the adjustment unit includes a rotating arm rotatably mounted on the base, and a drive mechanism for driving the rotating arm to rotate. The lower end of the jacking component is rotatably connected to the rotating arm. With the above structure, the drive mechanism drives the rotating arm to rotate, which in turn drives the jacking component to move up and down. This structural layout has the advantages of smooth transmission and compact structure.

[0011] Preferably, the drive mechanism includes a drive motor and an adjuster mounted on the base. The drive motor is connected to the adjuster via a synchronizing rod, and the rotating arm is fixedly connected to the output end of the adjuster. With this structure, the drive mechanism transmits power to the adjuster via the synchronizing rod, and the output end of the adjuster drives the rotating arm to rotate, offering advantages such as a large transmission ratio and high adjustment precision. Simultaneously, the adjuster has a self-locking characteristic, reliably locking the swing angle of the rotating arm after adjustment, maintaining seat posture stability, and ensuring the stability and safety of seat posture adjustment.

[0012] Preferably, the same adjustment unit includes two sets of rotating arms and two sets of angle adjusters. The two sets of angle adjusters are mounted on the same synchronizing rod. The two sets of rotating arms are fixedly connected to the output ends of the two sets of angle adjusters in a one-to-one correspondence. A retaining crossbar is provided between the two sets of rotating arms. The lower end of the pushing component is rotatably connected to the two sets of rotating arms through the retaining crossbar. This structure creates a more stable support structure, resulting in more balanced force distribution, effectively improving the load-bearing stiffness and smooth operation of the adjustment unit, and avoiding problems such as uneven loading and jamming caused by unilateral force distribution.

[0013] Preferably, the upper end of the push-up component is provided with a ball joint assembly. Using the above structure, the ball joint connection allows for adaptive adaptation to multi-directional angle changes during seat posture adjustment, effectively releasing motion constraints caused by spatial sway and ensuring smooth, unhindered omnidirectional seat posture adjustment.

[0014] Preferably, the system also includes a transition piece for fixed assembly to the bottom of the seat frame, with the upper end of the pushing component connected to the transition piece via a ball joint. This structure enables modular installation.

[0015] Preferably, the ball joint assembly includes a ball joint seat and a ball head that mates with the spherical surface of the ball joint seat; the ball joint seat is located on the upper end of the pushing member, and the ball head is mounted on the lower side of the transition member; or, the ball joint seat is located on the lower side of the transition member, and the ball head is located on the upper end of the pushing member. With this structure, the pushing member can not only pitch and rotate back and forth around the axis of the support shaft, but also achieve lateral micro-rotation through the spherical engagement of the ball head with the ball joint seat, thereby releasing the torsional constraints generated by multi-degree-of-freedom spatial motion.

[0016] Preferably, the pushing component has a lower connecting section and an upper connecting section bent to one side relative to the lower connecting section. The lower connecting section is hinged to the end of the rotating arm, and the ball head is located at the upper end of the upper connecting section. With this structure, the pushing component, being bent, effectively compresses the overall vertical dimension of the mechanism in its lowest position, resulting in a more compact layout of the adjustment unit, reducing the vertical space occupied by the device, and improving the device's spatial adaptability under the seat.

[0017] The second objective of this invention is to provide a universal flexible seat, the key feature of which is that the aforementioned universal posture adjustment module is installed at the bottom of the seat frame.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. The universal posture adjustment module provided by this invention, by setting at least three sets of adjustment units on the base, and the pushing parts of each set of adjustment units move independently or in coordination, can realize multi-dimensional universal posture adjustment such as front-end lifting, rear-end lifting, overall height adjustment, left tilt, and right tilt. It can provide zero-gravity adjustment and daily height adjustment, and can also generate active tilt compensation through lateral sway when the vehicle turns, to counteract centrifugal force and improve the ride comfort and safety of the vehicle.

[0020] 2. The three adjustment units are arranged in a triangle on the base. One set of adjustment units is located in the central front area of ​​the base, while the other two sets are symmetrically arranged on the left and right sides of the rear end of the base. This allows for tilting, lateral tilting, and height adjustment of the seat in space with a minimal number of adjustment units. This layout has the advantages of a refined structure, simple control, and low manufacturing and maintenance costs. Furthermore, the differential control of the two rear adjustment units is more conducive to lateral yaw, while the single front adjustment unit is more conducive to independent front lifting in a zero-gravity state.

[0021] 3. The universal attitude adjustment module provided by this invention uses a linkage transmission assembly with hinged push components and a rotating arm, and the push components are connected to the seat frame by a ball joint. The ball joint connection provides multi-axial spatial rotational freedom. When different adjustment units perform asymmetrical height adjustment, the ball joint connection can adaptively eliminate mechanical interference and torsional shear stress caused by inconsistent motion trajectories of each push component, ensuring a smooth and unhindered adjustment process and significantly extending the service life of the mechanism.

[0022] 4. The universal flexible seat provided by this invention can realize multi-degree-of-freedom universal posture adjustment of the seat, meeting the adaptive posture adjustment needs of the vehicle in various scenarios. Attached Figure Description

[0033] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0034] like Figure 1As shown, a omnidirectional flexible seat includes a seat frame B, with an omnidirectional adjustment module installed at the bottom of the seat frame B. The omnidirectional adjustment module enables multi-degree-of-freedom omnidirectional posture adjustment of the seat, meeting the adaptive posture adjustment needs of the vehicle in various scenarios. The structure of the omnidirectional adjustment module will be described in detail below.

[0035] Please refer to Figure 1 and 2 A universal posture adjustment module includes a base 1. For seats without fore-and-aft adjustment, the base 1 can be directly mounted on the car floor. For seats with fore-and-aft adjustment, the base 1 can be mounted on a seat slide rail C. The base 1 has at least three sets of adjustment units A, each set of adjustment units A equipped with a pusher component 31 capable of moving along the height direction. The pusher component 31 is used to connect to the bottom of the seat frame B. Figures 5 to 9 As shown, the pushing components 31 of each adjustment unit A can move independently or collaboratively in lifting and lowering motion, enabling functions such as raising the front and rear of the seat, adjusting the overall height, tilting left, and tilting right. Specific sub-scenarios include, but are not limited to, the following: 1. Reference Figure 8 1. Independently control the front end of seat frame B to raise it, causing seat frame B to tilt in a forward-high, backward-low position. Combined with backrest tilt adjustment, this creates a zero-gravity seating mode; 2. Reference Figure 9 All the pushing parts 31 of the adjustment unit A move up and down synchronously to adjust the height of the seat frame; 3. Reference Figure 5 and 6 During vehicle turns, each adjustment unit A works in concert to adjust the seat frame to tilt to the left or right, which can counteract the centrifugal force generated by the vehicle turning and improve the stability of the user's ride; 4. Through the coordinated work of each adjustment unit A, the seat cushion can be controlled to swing freely in the space, which, together with the in-vehicle audio-visual entertainment playback, can create a 4D stereoscopic cinema scene.

[0036] The number of adjustment units A can be three, four, five, or six; in this embodiment, three groups are preferred. (Refer to...) Figure 1 and 2Three sets of adjustment units A are arranged in a triangle on the base 1, with two sets symmetrically arranged at the rear end of the base 1 and the other set arranged in the middle of the front end of the base 1. This design, when applied to a seat, creates a symmetrical distribution structure with high load-bearing balance. Simultaneously, the three support points of the three sets of pushing components 31 define a support plane. Through the coordinated work of the three sets of adjustment units A, the seat frame B can be adjusted to any spatial angle, including left or right tilt. This allows the device to achieve tilting, lateral tilting, and lifting of the seat in space with a minimal number of adjustment units A, offering advantages such as refined structure, simple control, and low manufacturing and maintenance costs. The core function of adjustment unit A is to control the up-and-down movement of the pushing component 31 and provide stable locking strength when adjustment is not required. In this embodiment, the structure of each set of adjustment units A is identical, as detailed below:

[0037] like Figure 3 As shown, the adjustment unit A includes a rotating arm 32 rotatably mounted on the base 1, and a drive mechanism 2 for driving the rotating arm 32 to rotate. The lower end of the pushing component 31 is rotatably connected to the rotating arm 32. The drive mechanism 2 drives the rotating arm 32 to rotate, which in turn drives the pushing component 31 to move up and down. This structural layout has the advantages of smooth transmission and compact structure.

[0038] Combined Figure 4 As shown, the drive mechanism 2 includes a drive motor 21 and an adjuster 23 mounted on the base 1. The drive motor 21 is connected to the adjuster 23 via a synchronizing rod 22, and the rotating arm 32 is fixedly connected to the output end of the adjuster 23. The drive mechanism 2 transmits power to the adjuster 23 via the synchronizing rod 22, and the output end of the adjuster 23 drives the rotating arm 32 to rotate, which has the advantages of large transmission ratio and high adjustment accuracy. At the same time, the adjuster 23 has a self-locking characteristic, which can reliably lock the swing angle of the rotating arm 32 after adjustment, maintain the stability of the seat posture, and ensure the stability and safety of seat posture adjustment.

[0039] refer to Figure 2 and Figure 4 In this embodiment, an upwardly extending bracket plate 11 is fixed on the base 1, and the drive motor 21 and the angle adjuster 23 are assembled on the bracket plate 11.

[0040] In addition to the above-described embodiments, adjustment unit A can also employ, for example... Figure 10The illustrated implementation describes an adjustment unit A comprising a drive motor 21, two sets of rotating arms 32, and two sets of angle adjusters 23. The two sets of angle adjusters 23 are mounted on the same synchronizing rod 22, and the two sets of rotating arms 32 are correspondingly fixed to the output ends of the two sets of angle adjusters 23. The drive motor 21 is mounted on one of the support plates 11. A retaining crossbar 33 is provided between the two sets of rotating arms 32, and the lower end of the pushing component 31 is rotatably connected to the two sets of rotating arms 32 via the retaining crossbar 33. The drive motor 21 drives the two sets of angle adjusters 23 via the synchronizing rod 22, causing the two sets of rotating arms 32 to rotate synchronously from their output ends, which in turn drives the pushing component 31 to move up and down via the retaining crossbar 33. This design using two angle adjusters 23 and two rotating arms 32 creates a more stable support structure, resulting in more balanced force distribution. This effectively improves the load-bearing rigidity and smooth operation of the adjustment unit, avoiding uneven loading and jamming problems caused by unilateral force application.

[0041] The upper end of the jacking component 31 is equipped with a ball joint assembly. The advantage of this design is that the jacking component 31 can push up and down more flexibly, and the ball joint connection can ensure that the movement of each adjustment unit A does not interfere with each other, thus improving reliability.

[0042] To achieve modular installation, refer to... Figure 1 and 2 In this embodiment, the omnidirectional attitude adjustment module also includes a transition piece 4, which is flat or frame-shaped. The transition piece 4 is used for fixed assembly at the bottom of the seat frame B, and the upper end of the pushing component 31 is connected to the transition piece 4 by a ball joint. The ball joint connection provides multi-axial spatial rotational freedom. When different adjustment units A perform asymmetrical height adjustment, the ball joint connection can adaptively eliminate the mechanical interference and torsional shear stress caused by the inconsistent motion trajectories of each pushing component 31, ensuring that the entire mechanism is smooth, without jamming or abnormal noise during omnidirectional attitude adjustment, and extending the service life of the mechanism.

[0043] Refer to Figure 4 and Figure 8In this embodiment, the ball joint assembly includes a ball joint seat 51 and a ball head 52 that spherically engages with the ball joint seat 51. The ball joint seat 51 is located on the upper end of the pushing member 31, and the ball head 52 is installed on the lower side of the transition member 4. In this embodiment, a downwardly extending support 41 is fixedly provided on the lower side of the transition member 4. This support 41 is a U-shaped support, and both ends of the ball head 52 are provided with radially outwardly extending support shafts 53. The two support shafts 53 are respectively fixedly supported at both ends of the U-shaped support. This design allows the pushing member 31 to not only pitch and rotate back and forth around the axis of the support shafts 53, but also to achieve lateral micro-rotation through the spherical engagement of the ball head 52 with the ball joint seat 51, thereby releasing the torsional constraints generated by multi-degree-of-freedom spatial motion. In addition, this structure is easy to assemble, has stable connection stiffness, and can maintain the reliability of the support while ensuring the degree of freedom of motion. In addition to the above, the ball joint assembly can also be arranged with the ball head located on the upper end of the pushing member 31 and the ball joint seat located on the lower side of the transition member 4.

[0044] Furthermore, such as Figure 3 As shown, the push-up component 31 has a lower connecting section 311 and an upper connecting section 312 that bends to one side relative to the lower connecting section 311. The lower connecting section 311 is hinged to the end of the rotating arm 32, and the ball head 52 is located at the upper end of the upper connecting section 312. With this design, the push-up component 31 adopts a bent structure, which effectively compresses the overall vertical dimension of the mechanism when it is in its lowest position, making the layout of the adjustment unit A more compact, reducing the vertical space occupied by the device, and improving the spatial adaptability of the device under the seat.

[0045] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention.
