Description

Technical Field

[0001] This invention relates to the technical field of automobile seats, and in particular to an automobile seat with adaptive massage equipment. Background Technology

[0002] With the development of the automotive industry and the improvement of people's living standards, consumers' demands for car ride comfort are increasing. Car seats are no longer just for basic seating and safety needs; integrated intelligent massage functions have become an important feature for mid-to-high-end models to enhance the driving experience and luxury. The mainstream car massage seats on the market mainly use pneumatic airbags or electric motors for driving. These systems typically have preset massage trajectories and intensities, and use programmed control of the inflation and deflation of airbags or the movement of massage heads to achieve massage modes such as kneading, vibration, and wave motions.

[0003] However, existing car massage seats generally use fixed-program massage modules. When passengers change their sitting posture (turning to the side, crossing their legs, or leaning back), the contact surface and pressure distribution between their back and the seat will change in real time. This causes the fixed massage module to be unable to adapt and adjust, resulting in problems such as misaligned massage points, lack of support in some areas, and difficulty in conforming to complex physiological curves. This not only greatly reduces the massage effect, but also aggravates riding fatigue and discomfort due to uneven pressure distribution. Summary of the Invention

[0004] The purpose of this invention is to provide a car seat with adaptive massage equipment, aiming to solve the problems in the prior art.

[0005] The present invention is implemented as follows: a car seat with adaptive massage equipment includes a seat body and a massage module disposed thereon. The massage module includes a lower base plate, an upper base plate, an air pump, multiple massage airbag groups and two sets of symmetrically arranged adaptive actuators. Each set of adaptive actuators includes a guide plate, three slide blocks slidably disposed on the guide plate, and a linkage assembly. The slide blocks are driven by the air pump and can be raised and lowered independently. A support frame is installed on the middle slide, and the support frame is connected to a telescopic rod; diagonal tie rods are rotatably connected to the slides on both sides. The massage airbag assembly is connected to the ends of the telescopic rod and the diagonal rod via universal joints; The linkage components are configured with one of the following linkage relationships: On the same guide plate, the middle telescopic rod retracts, driving the two diagonal tie rods in the same group to lift synchronously; On the same guide plate, when the diagonal tie rod on one side is lowered, it drives the diagonal tie rod on the other side to rise synchronously. When the diagonal lever on one side of one set of adaptive actuators is lowered, it drives the diagonal lever on the same side of the other set of adaptive actuators to rise synchronously.

[0006] Preferably, both the lower substrate and the upper substrate are provided with solenoid valves for controlling the opening and closing of the air passage. The air pump is connected to the solenoid valves through an air guide pipe. By controlling the solenoid valves, the airflow to each of the massage airbag groups is adjusted to drive the massage airbag groups to perform massage actions.

[0007] Preferably, the guide plate has three guide grooves evenly distributed inside, and the guide plate also has a guide rod that passes through the three guide grooves; The slide block is slidably mounted on the outside of the guide rods of the three guide slots, and an adjusting airbag and a first return spring are respectively provided in the upper and lower parts of the slide block in each guide slot. The adjusting airbag is connected to the air pump.

[0008] Preferably, the linkage component includes: The guide plate has a take-up and release roller rotatably mounted on the slide blocks on both sides of the guide plate, a pressure roller rotatably mounted on the lower end of the telescopic rod, and a rocker plate mounted between the two sets of guide plates. The rocker plate has a V-shaped structure.

[0009] Preferably, a slider is provided on one side of the lower end of the telescopic rod, which penetrates and extends to the outside of one side of the stand. The pressure roller is connected to the surface of the slider through a rotating shaft, and a second return spring is also provided inside the stand, the end of which abuts against the lower end of the telescopic rod.

[0010] Preferably, a fulcrum is provided on one side of the diagonal tie rod, and the fulcrum is a fixed pulley structure, the position of which is higher than the pressure roller; A tension cable is connected between the two take-up and take-off rollers, the tension cable passing over the upper part of the fulcrum and passing under the pressure roller.

[0011] Preferably, a toothed ring is coaxially fixed on the take-up and release rollers, and a toothed plate that meshes with the toothed ring is fixed on one side of the guide plate.

[0012] Preferably, a connecting plate is provided between the slides on the same side of the two sets of adaptive actuators, and a support is provided on the connecting plate, with the middle part of the rocker plate rotatably connected to the support.

[0013] Preferably, the surface of the seat body is covered with a surface coating, which covers the massage contact surface of the massage airbag assembly.

[0014] The beneficial effects of the car seat with adaptive massage equipment disclosed in this invention are as follows: This solution, through the integrated adaptive actuator and linkage balance mechanism, can sense and respond to changes in the passenger's sitting posture in real time, and dynamically adjust the position of the massage airbag group and the shape of the surface covering, thereby effectively solving the problems of massage point misalignment and local suspension. This allows the system to intelligently make the massage module closely fit the physiological curve of the human body, providing uniform and accurate support and massage, regardless of the passenger's sitting posture. This greatly improves the accuracy and comfort of the massage and effectively alleviates riding fatigue caused by uneven pressure distribution. Attached Figure Description

Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting this invention.

[0019] The implementation of the present invention will be described in detail below with reference to specific embodiments.

[0020] In this embodiment: Reference Figures 1-4 The diagram shows a preferred embodiment of the present invention.

[0021] This embodiment of a car seat with adaptive massage equipment includes a seat body 1 and a massage module 2 disposed thereon. The massage module 2 includes a lower base plate 21, an upper base plate 22, an air pump 23, multiple massage airbag assemblies 26, and two sets of symmetrically arranged adaptive actuators 25. The lower base plate 21 is embedded in the seat cushion of the seat body 1, and the upper base plate 22 is embedded in the backrest of the seat body 1. The air pump 23 is disposed below the seat body 1 and has a pressure sensor for detecting whether the seat is in use. Both the lower base plate 21 and the upper base plate 22 are provided with control air... The solenoid valve controls the opening and closing of the air path. The air pump 23 is connected to the solenoid valve through the air guide pipe 24. By controlling the solenoid valve, the airflow to each of the massage airbag groups 26 is regulated to drive the massage airbag groups 26 to perform massage actions. The system realizes real-time control of the solenoid valve through PLC controller programming, precisely controlling the opening and closing of each air path and the inflation and deflation of gas, so that the massage module 2 can perform massage operations in a variety of predetermined modes. After the pressure sensor detects that the passenger has sat down, it transmits a signal to the PLC controller, which then automatically starts the air pump 23 and the corresponding massage program, realizing intelligent start and stop.

[0022] The air pump 23 is connected to the lower substrate 21 and the upper substrate 22 respectively through the air guide tube 24, and controls the airflow direction through the solenoid valve to drive the massage airbag assembly 26 to perform kneading and tapping massage actions. Specifically, by rapidly switching the solenoid valve, the airflow is controlled to alternately fill and discharge specific massage airbag assemblies 26, which can simulate the continuous pressure of human hand kneading and the rhythm of tapping, effectively relieving muscle fatigue.

[0023] It is worth noting that, such as Figures 5-9 As shown, three guide grooves 252 are evenly distributed within the guide plate 251, and a guide rod 253 is also provided within the guide plate 251, penetrating the three guide grooves 252. The slide 256 is slidably mounted on the outside of the guide rods 253 of the three guide grooves 252. An adjusting airbag 254 and a first return spring 255 are respectively provided in the upper and lower parts of the slide 256 within each guide groove 252. The adjusting airbag 254 is connected to the air pump 23. When the air pump 23 is started, it inflates or deflates the adjusting airbag 254 according to a preset program. The change in the volume of the adjusting airbag 254 pushes the slide 256 up and down along the guide rod 253 within the guide groove 252, thereby adjusting the position of the massage airbag assembly 26. Furthermore, the first return spring 255 provides a counterforce during the deflation of the adjusting airbag 254, assisting the slide 256 in quickly returning to its original position to adapt to different passenger body shapes and sitting postures, accurately adjusting the massage position and effectively improving the accuracy of the massage.

[0024] The linkage component includes: take-up and release rollers 2561 rotatably disposed on slide blocks 256 on both sides of guide plate 251, pressure rollers 25661 rotatably disposed at the lower end of telescopic rod 2564, and rocker plate 259 disposed between the two sets of guide plates 251, the rocker plate 259 having a V-shaped structure.

[0025] exist Figure 9 In the middle, a slider 2566 is provided on one side of the lower end of the telescopic rod 2564, which penetrates and extends to the outside of one side of the upright frame 2563. The pressure roller 25661 is connected to the surface of the slider 2566 through a rotating shaft. The upright frame 2563 is also provided with a second return spring 2565 whose end abuts against the lower end of the telescopic rod 2564. When the middle massage airbag assembly 26 is compressed, it pushes the telescopic rod 2564 to contract and compress the second return spring 2565, while driving the pressure roller 25661 at its lower end to move down. A fulcrum 2569 is provided on one side of the diagonal tie rod 2568. The fulcrum 2569 is a fixed pulley structure and its position is higher than that of the pressure roller 25661. Furthermore, Figure 6 In this assembly, a tension cable 2567 connects the two take-up and release rollers 2561. The tension cable 2567 passes over the upper part of the fulcrum 2569 and passes under the pressure roller 25661. When the pressure roller 25661 moves downward, it presses down on the tension cable 2567 passing underneath, thus changing the cable's tension. The tension cable 2567 pulls the diagonal pull rod 2568 with the fulcrum 2569 towards the pressure roller 25661, causing the diagonal pull rod 2568 to rotate along its pivot connection. Simultaneously, when the massage airbag assembly 26 on one of the diagonal pull rods 2568 is compressed, the tension cable 2567 pulls the other diagonal pull rod 2568 upward. Based on the compression of the middle massage airbag assembly 26, the shape of the surface covering is adaptively adjusted to better conform to the curve of the human back, providing passengers with a more comfortable and precise massage experience.

[0026] It is worth noting that a toothed ring 2562 is coaxially fixed on the take-up and release roller 2561, and a toothed plate 2511 that meshes with the toothed ring 2562 is fixed on one side of the guide plate 251. This allows the slide block 256 to move synchronously with the take-up and release roller 2561 during the adjustment of the slide block 256 position by adjusting the airbag 254 and the first return spring 255. During this process, the precise engagement between the toothed ring 2562 and the toothed plate 2511 ensures the smooth rotation of the take-up and release roller 2561, thereby synchronously taking up and releasing the traction cable 2567, ensuring that the traction cable 2567 is always under tension.

[0027] The meshing of the toothed ring 2562 and the toothed plate 2511 forms a precise linear control mechanism that converts the linear displacement of the slide block 256 into the rotational motion of the take-up and release rollers 2561. Its tooth profile design ensures that the transmission is slip-free and has a self-locking characteristic, which can maintain stability in any position.

[0028] A connecting plate 257 connects the slides 256 on the same side of the two sets of adaptive actuators 25. A support 258 is provided on the connecting plate 257, and the middle part of the rocker arm 259 is rotatably connected to the support 258. The rocker arm 259 enables force transmission between the left and right sets of adaptive actuators 25. When the massage airbag assembly 26 on one side of the diagonal pull rod 2568 is compressed, the diagonal pull rod 2568 pushes the rocker arm 259 downwards on that side, while the other side correspondingly tilts upwards. This, in turn, pushes the diagonal pull rod 2568 on the other side upwards, causing the surface covering of the massage airbag assembly 26 on that side to change accordingly, better adapting to the curve of the other side of the human back. This allows the seat surface covering 11 to adjust its shape dynamically and in real time according to the pressure on different parts of the human back. Whether the passenger is sitting upright or sideways, they can feel a uniform and fitting massage force, further improving the comfort and precision of the massage, providing passengers with a comprehensive and high-quality massage experience.

[0029] The V-shaped rocker 259 serves as a cross-regional force balancing mechanism. Its core function is to compensate for pressure on both sides of the body. For example, when a passenger crosses their legs and their body leans to one side, the pressure on that side increases. Through the rocker 259 mechanism, the support force on the other side can be automatically increased, thereby actively correcting the position of the massage airbag group 26, maintaining the consistency of massage force on both sides of the passenger's spine, and effectively preventing unilateral muscle fatigue during long-distance driving.

[0030] The surface of the seat body 1 is covered with a surface covering 11, which is made of soft materials such as leather or high-grade knitted fabric. The surface covering 11 covers the massage contact surface of the massage airbag assembly 26, which not only effectively avoids direct contact between the massage airbag assembly 26 and the occupant, but also further enhances the comfort of the ride by utilizing the elasticity and cushioning properties of the fabric.

[0031] Working principle: During operation, the air pump 23 serves as the power source, delivering airflow through the air duct 24. The PLC controller programs and controls the opening and closing of each solenoid valve, thereby precisely manipulating the inflation and deflation of specific massage airbag groups 26 to perform massage actions in predetermined modes such as kneading and tapping. Its adaptive function is achieved through two key mechanisms: First, by adjusting the inflation and deflation of the airbags 254, the slide 256 is moved, thereby adjusting the vertical position of the massage airbag assembly 26 to adapt to different body shapes; second, through a linkage and balancing mechanism consisting of a telescopic rod 2564, a pressure roller 25661, a traction cable 2567, and a rocker 259, the pressure changes on the occupant's back are sensed in real time. When one side is under pressure, the force signal can be transmitted to the other side through the cable and the V-shaped rocker 259, dynamically adjusting the shape and support strength of the massage airbags on both sides to ensure that the massage points always accurately conform to the curves of the human body, achieving adaptive massage.

[0032] This solution, through the integrated adaptive actuator 25 and linkage balancing mechanism, can sense and respond to changes in the passenger's sitting posture (side sitting or leg crossing) in real time, dynamically adjusting the position of the massage airbag assembly 26 and the shape of the surface covering 11. This effectively solves the problems of massage point misalignment and local suspension. This allows the system to intelligently make the massage module 2 closely conform to the physiological curves of the human body, providing uniform and accurate support and massage, regardless of the passenger's sitting posture. This greatly improves the accuracy and comfort of the massage, effectively alleviates riding fatigue caused by uneven pressure distribution, and meets the market's demand for a high-end, intelligent driving experience.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
