Description

Technical Field

[0001] The present invention relates to the technical field of automobile seats, in particular to a diversified linkage adjustment seat. Background Art

[0002] As an essential component of a car's interior, car seats are of undeniable importance. They are not only the cornerstone of a driver's enjoyment but also a crucial defense against driving safety. During a fast-moving vehicle, seats, with their superior shock absorption, effectively absorb road bumps, providing a stable and comfortable ride for passengers. They also support the body in an optimal posture, reducing fatigue during long drives. In emergencies, the seats work closely with the seatbelt to quickly secure the occupant, preventing secondary injuries from violent vehicle jolts and ensuring safety on every journey. With the rapid development of the automotive industry, people's demands for cars have evolved far beyond simply being a means of transportation, embracing a pursuit of higher performance and a more comfortable driving experience. The evolution of car seats epitomizes this trend. From the earliest, simple designs that met only basic requirements to today's ergonomically designed seats meticulously shaped to the human body, to the use of premium materials for enhanced tactility and comfort, every innovation has been designed to enhance passenger enjoyment.

[0003] Furthermore, to meet the personalized needs of diverse consumers and address increasingly complex traffic environments and stringent safety standards, car seats are constantly expanding in functionality, with increasingly flexible and diverse adjustment methods and safety features continuously upgraded. From manual to electric adjustment, from basic protection to active safety systems, seats have become a highlight of automotive technological innovation, carrying people's aspirations and expectations for the future of travel.

[0004] Body compatibility in car seats is crucial to the driving experience. Drivers and occupants of different body types have significantly different seat requirements, including varying requirements for width and support. In a seven-seat MPV with individual seats, heavier passengers may experience insufficient support and comfort, while thinner passengers may find the wide, thick seats uncomfortable and unable to find the right fit. This significantly impacts ride comfort, safety, and ease of operation. Summary of the Invention

[0005] (1) Technical problems solved In response to the deficiencies in the prior art, the present invention provides a diversified linkage-adjustable seat. With its unique design, the diversified linkage-adjustable seat can be adjusted according to the needs of passengers of different body shapes. The driving structure drives the slide plate to slide in the slide groove to achieve precise adjustment of the seat width. The driving motor serves as a power source and cooperates with the driving structure, linkage structure and load-bearing rod to ensure a smooth and efficient adjustment process. For fatter passengers, the seat can increase the distance between the two sides, enhance wrapping and support, and improve comfort, while for thinner passengers, the width can be reduced to find the most suitable fit point. This not only significantly improves the driving comfort, allows all parts of the body to be properly accommodated, reduces fatigue and distraction caused by seat discomfort, but also greatly enhances driving safety, ensures body stability during driving, and convenient operation, thereby comprehensively optimizing the driving experience and other advantages.

[0006] (2) Technical solution To achieve the above-mentioned object, the present invention provides the following technical solution: a diversified linkage adjustable seat, comprising a base plate, a backboard fixedly mounted on one side of the upper surface of the base plate, a slide groove formed on the side of the backboard, and two sets of slide plates mounted in relative sliding relation within the slide groove; A connecting rod is fixedly installed on one side of the upper surface of the base plate close to the back plate, a frame is fixedly installed on the inner side of the connecting rod, and a bearing rod is fixedly installed on the side, a driving structure is fixedly installed inside the frame, and the side gears of the driving structure are connected with a linkage structure, and a controller is fixedly installed on the bottom end of the base plate.

[0007] Preferably, a baffle is fixedly installed on the side of the skateboard.

[0008] Preferably, the top end of the bottom plate is configured as an inclined surface, and a seating area is formed between the upper surface and the baffle, and the seating area is made of a soft material.

[0009] Preferably, the driving structure includes a driving motor fixedly mounted inside the frame, and a driving wheel is fixedly mounted on the rotor end at the axis of the driving motor.

[0010] Preferably, the linkage structure includes a linkage wheel meshed with the driving wheel, a positive and negative threaded screw is fixedly installed through the axis of the linkage wheel, and two groups of movable blocks are installed on the outer peripheral surface of the positive and negative threaded screw for rotation relative to the thread.

[0011] Preferably, the two groups of slide side edges are fixedly connected to the two groups of moving blocks respectively.

[0012] Preferably, a rubber pad is connected to the side of the backrest.

[0013] Preferably, there are two groups of bearing rods, which are relatively fixedly installed on both sides of the top of the connecting rod, and the inner sides of the opposite sides of the bearing rods are rotatably connected to the two ends of the positive and negative threaded rods.

[0014] Preferably, the controller is linearly connected to the drive motor.

[0015] Preferably, the upper surface of the bottom plate, away from the seating area and close to the outer side of the baffle, is wrapped with leather material.

[0016] Compared with the prior art, the present invention provides a diversified linkage adjustment seat with the following beneficial effects: 1. This invention provides passengers with a comfortable and safe riding environment through a series of carefully designed structures and functions. First, the sliding plates and baffles on both sides of the seat effectively support passengers, preventing them from slipping due to bumps, braking, and other situations during driving, thereby ensuring a stable and safe ride. Second, the inclined design at the top of the base allows the connection between the seat and the passenger to better conform to the human leg and foot posture, allowing for a more natural and comfortable leg position, reducing pressure and discomfort, and enhancing the seat's design and aesthetic appeal. Furthermore, the rubber pads on the sides of the backrest provide soft and elastic support for the passenger's back, alleviating the pressure of hard board materials on the back or sides. The cushions also slightly deform with the body's posture, better conforming to the body's curves and making it particularly suitable for prolonged leaning. The upper surface of the base, away from the seat and near the outer baffles, is covered with leather material, enhancing the tactile comfort of the seat edge and reducing friction or collision damage caused by hard edges and corners. The cushions are both wear-resistant and easy to clean, extending the service life and enhancing the overall aesthetics.

[0017] 2. The width of the seat can be dynamically adjusted according to the body shape of the passenger. After the drive motor in the drive structure is started, a series of gear meshing and positive and negative screw transmission are used to convert the rotational motion into linear motion, driving the two sets of slides to slide relative to each other in the slide groove, thereby achieving precise control of the seat width. This adjustment method ensures that the two sets of moving blocks move synchronously and symmetrically by using gear meshing and positive and negative screw transmission to avoid unilateral offset; the design of the positive and negative screws makes the relative movement speed of the two sets of moving blocks consistent, ensuring a smooth seat width adjustment process and avoiding jamming or tilting; the speed regulation function of the drive motor can achieve micron-level adjustment to meet the requirements of precise control. At the same time, the bearing rod provides rigid support and limit for both ends of the positive and negative screws to prevent the screws from bending, shaking or falling out of the threaded fit, ensuring the smoothness, transmission efficiency, impact resistance and safety of the seat adjustment. The controller is linearly connected to the drive motor to realize the control of the start and stop of the drive motor and the precise control of the speed and torque, ensuring a smooth and delay-free seat adjustment process. The diversified linkage adjustment structure realizes a convenient, precise and stable width adjustment function through the coordinated work of various components. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] A baffle 41 is fixedly mounted on the side of the slide 4; The baffles 41 on the sides of the two sets of skateboards 4 provide support for the passengers on both sides to prevent the passengers from slipping due to vehicle bumps, braking, etc. during the ride. The top of the bottom plate 1 is set as an inclined surface, and a seating area 11 is formed between the upper surface and the baffle 41. The seating area 11 is made of soft material; When a passenger sits on the seat, the beveled surface allows the connection between the passenger and the seat to better fit the leg and foot posture of the human body, making the legs more natural and comfortable when placed, reducing the pressure and discomfort at the connection between the legs and the seat. At the same time, the beveled surface can add a unique design and beauty to the seat, making the overall shape of the seat more smooth and elegant, avoiding the stiffness caused by right-angle connections, and enhancing the appearance quality and artistic value of the seat. The driving structure 8 includes a driving motor 81 fixedly mounted inside the frame 6, with a driving wheel 82 fixedly mounted on the rotor end of the driving motor 81 at the axis; the linkage structure 9 includes a linkage wheel 91 meshing with the driving wheel 82, with a positive and negative threaded rod 92 fixedly mounted through the axis of the linkage wheel 91, and two sets of moving blocks 93 mounted on the outer circumference of the positive and negative threaded rod 92 so as to rotate relative to the thread; the sides of the two sets of slides 4 are respectively fixedly connected to the two sets of moving blocks 93; The driving motor 81 adopts the PBL2410018 model of the current Lihui brushless motor on the market. Its driving principle is the existing technology, and the rest of the circuit principles will not be described in detail. The driving motor 81 adopts the PBL2410018 model Lihui brushless motor currently available on the market. When the driving motor 81 is started, the rotor end of the driving motor 81 begins to rotate, driving the driving wheel 82 to start rotating. The driving motor 81 provides power to the driving wheel 82. At this time, the gear end of the driving wheel 82 drives the interlocking wheel 91 meshing with the driving wheel 82 to start rotating. The interlocking wheel 91 drives the positive and negative threaded rods 92 at the axis to rotate. While the positive and negative threaded rods 92 rotate, the two groups of moving blocks 93 whose outer circumferences rotate relative to the threads are relatively close to or away from each other. At this time, the moving blocks 93 drive the slide 4 to slide relatively inside the slide groove 3, thereby achieving the effect of adjusting the distance between the two groups of slides 4. By cooperating with the drive motor 81, the linkage wheel 91, the positive and negative threaded rods 92 and the moving block 93, the distance between the two sets of slide plates 4 can be accurately controlled to realize dynamic adjustment of the seat width, so that the seat width can be automatically adjusted according to the body shape of the occupant, providing more fitting support and improving comfort. The gear meshing and positive and negative threaded rods 92 are used for transmission to convert the rotary motion into linear motion, ensuring that the two sets of moving blocks 93 move synchronously and symmetrically to avoid unilateral offset. The design of the positive and negative threaded rods 92 makes the relative movement speed of the two sets of moving blocks 93 consistent, ensuring a smooth seat width adjustment process to avoid jamming or tilting. The speed regulation function of the drive motor 81 can realize micron The seat is adjusted in stages to meet the demand for precise control of the seat width. The driving wheel 82 and the linkage wheel 91 transmit power through gear meshing. The positive and negative threaded screws 92 and the moving blocks 93 are matched through threads. The structure is compact and the force is evenly distributed. The positive and negative threaded screws 92 drive two sets of moving blocks 93 at the same time. The force is symmetrical, which reduces unilateral wear and extends the life of components. The gear meshing and screw transmission have high mechanical efficiency and can withstand large torque and load. It is suitable for multiple adjustment scenarios. Through unified control of the drive motor 81, the passenger only needs to start the drive motor 81 to automatically complete the adjustment. No manual operation is required. The seat width can be automatically adjusted according to the passenger's instructions, and the operation is simple. The side of the backboard 2 is connected with a rubber pad; The rubber cushion provides support for the passenger's back, making the passenger feel more comfortable when using it. The rubber cushion is soft and has a certain elasticity. When the user leans on the backrest 2, the cushion can effectively relieve the pressure of the hard plate on the back or side, reducing discomfort. At the same time, the rubber cushion can slightly deform with the human body posture, better fit the curve of the back or side waist, and provide more uniform support. It is especially suitable for scenes where the passenger leans for a long time. When the slide plate 4 is adjusted, the rubber cushion can automatically squeeze or stretch, using the adjustment function of the seat; There are two groups of bearing rods 7, which are relatively fixedly installed on both sides of the top of the connecting rod 5. The inner sides of the bearing rods 7 are rotatably connected to the two ends of the positive and negative threaded rods 92; The two ends of the positive and negative threaded rods 92 are supported and limited by two sets of bearing rods 7. The two sets of bearing rods 7 are respectively fixed on both sides of the top of the connecting rod 5 to provide rigid support for the two ends of the positive and negative threaded rods 92 to prevent the threaded rods from bending or shaking under high-speed rotation or high load. The positive and negative threaded rods 92 are the core components for driving the seat width adjustment. Their stability directly affects the movement accuracy of the moving block 93. The limiting design of the bearing rods 7 can ensure that the threaded rods remain in a straight line state, avoiding tilting or vibration caused by uneven force, thereby ensuring the stability of the seat adjustment. The bearing rods 7 ensure that the threaded rods remain in a straight line state by limiting the axial displacement of the positive and negative threaded rods 92. It only rotates along its own axis to avoid the deviation of the screw rod or the loss of the thread due to external force. The positive and negative thread screw rods 92 need to drive the two sets of moving blocks 93 at the same time to achieve symmetrical movement. The limiting effect of the bearing rod 7 can prevent the radial runout of the screw rod when transmitting torque, ensuring the synchronous movement of the two sets of moving blocks 93. The two sets of bearing rods 7 form a symmetrical support, which can balance the torque and axial force generated by the positive and negative thread screw rods 92 during operation, avoiding structural damage caused by unilateral force. By improving stability, transmission efficiency, impact resistance and safety, the comprehensive performance of the seat adjustment structure is further enhanced, and the core function of the positive and negative thread screw rods 92 is guaranteed. The controller 10 is linearly connected to the drive motor 81; The controller 10 uses the currently available 716PCASTS0060 FOC controller on the market, which is linearly connected to the drive motor 81 to achieve control of the start and stop of the drive motor 81, and achieve precise control of the speed and torque to ensure a smooth and delay-free seat adjustment process; The upper surface of the bottom plate 1, away from the seat area 11 and close to the outer side of the baffle 41, is wrapped with leather material; The upper surface of the base plate 1, away from the seat area 11 and close to the outside of the baffle 41, is wrapped with leather material to wrap the rigid adjustment structure of the seat. This can improve the tactile comfort of the seat edge and reduce the friction or collision damage to the user caused by hard edges and corners. At the same time, the wear resistance and easy-to-clean properties of the leather material can extend the service life, enhance the overall aesthetics, and make the seat structure more coordinated and unified in functionality and design.
