[0003] Currently, the mainstream car massage seats on the market mainly adopt two technical solutions: pneumatic drive or electric motor drive. The massage sensation of pneumatic drive car seats on the market is too gentle, mainly consisting of large-area squeezing and slow kneading. It cannot achieve deep, impactful acupressure-style tapping massage, and it is difficult to effectively relieve muscle soreness after strenuous exercise or stiffness caused by long-term driving. Summary of the Invention

[0004] The purpose of this invention is to provide a car seat with a kneading and massage function, in order to solve the problems in the prior art.

[0005] The present invention is implemented as follows: a car seat with kneading and massage function includes a seat body and a massage module disposed thereon. The massage module includes a lower base plate, an upper base plate and an air pump. The lower base plate and the upper base plate are respectively provided with a plurality of massage actuators and a solenoid valve for controlling the air circuit opening and closing. The air pump is connected to the lower substrate and the upper substrate respectively through an air guide pipe, and the airflow direction is controlled by an electromagnetic valve to drive the massage actuator to perform kneading and tapping massage actions; The massage actuator includes a guide plate and three tapping cylinders. The guide plate has a central disc and three rectangular arms extending equidistantly from the central disc along the circumference. The tapping cylinders are slidably disposed in each rectangular arm through guide plates on both sides and can perform expansion and contraction movements synchronously. Each of the tapping cylinders is provided with an air bag at its end. The air bag has an annular support and an expansion part. The air bag rotates during the sliding of the tapping cylinder. The tapping cylinder is also provided with a tapping plate inside, which is used to tap the air bag to produce a tapping effect.

[0006] Preferably, the central disk of the guide plate is axially connected to a rotating ring via a bearing, a fixed plate is provided on the inner side of the central disk of the guide plate, a moving plate is provided on one side of the rotating ring, and an airbag is provided between the fixed plate and the moving plate. The guide plate also has an inlet at its central disc for introducing an air duct into the massage module.

[0007] Preferably, the central disk of the guide plate is circumferentially connected with three connecting rods at equal intervals, and each connecting rod is rotatably connected to the corresponding side of the striking cylinder through a push-pull rod; A first reset spring is engaged between the side of the striking cylinder facing away from the push-pull rod and the inner wall of the rectangular arm end of the support plate.

[0008] Preferably, a support plate is provided around the guide plate, and a toothed plate is installed on the side of the support plate near the rectangular arm of the guide plate; The annular support portion of the air bag has a slot at its axis, the top of the striking cylinder has a retaining ring that matches the slot, and the air bag is located outside the slot of the annular support portion and has a toothed ring that meshes with the toothed plate.

[0009] Preferably, a telescopic rod is vertically installed inside the striking cylinder, penetrating its bottom, and a sealing ring is provided on the outer side of the bottom of the striking cylinder, with the inner wall of the sealing ring abutting against the surface of the telescopic rod.

[0011] Preferably, the eccentric bottom of the striking cylinder is provided with an air extraction pipe, and a second return spring is sleeved on the outside of the telescopic rod. The telescopic rod has an air hole on the side below the piston plate.

[0012] Preferably, a pressure plate is adhered to the surface of the inflatable part of the air bag. The pressure plate is sheet-like or protruding. The surface of the seat body is covered with a surface coating, which covers the surface of the pressure plate of the massage actuator.

[0013] The beneficial effects of the car seat with kneading and massage function disclosed in this invention are: 1.

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. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[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 kneading and massage function 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, and an air pump 23. 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. The lower base plate 21 and the upper base plate 22 are respectively provided with a plurality of massage actuators 25 and solenoid valves for controlling the opening and closing of the air passages. The system realizes real-time control of the solenoid valves through PLC controller programming, precisely manipulates the opening and closing of each air passage and the gas filling and releasing, so that the massage module 2 can perform a variety of predetermined massage operations.

[0022] The air pump 23 is connected to the lower base plate 21 and the upper base plate 22 respectively through the air guide pipe 24, and controls the airflow direction through the solenoid valve to drive the massage actuator 25 to perform kneading and tapping massage actions. It is worth noting that, referring to Figures 5-6 As shown, the massage actuator 25 includes a guide plate 251 and three tapping cylinders 254. The guide plate 251 has a central disc and three rectangular arms extending equidistantly from the central disc along the circumference. Each rectangular arm is provided with a sliding groove. The tapping cylinders 254 are slidably disposed in each rectangular arm through guide plates 2541 that cooperate with the sliding grooves on both sides, and can be driven to perform expansion and contraction movements synchronously. Furthermore, each of the tapping cylinders 254 is provided with an air bag 253 at its end. The air bag 253 has an annular support part and an expansion part. The air bag 253 rotates during the sliding process of the tapping cylinder 254. The tapping cylinder 254 is also provided with a tapping plate 2546 inside, which is used to tap the air bag 253 to produce a tapping effect.

[0023] To enable the striking cylinder 254 to slide within the rectangular arm of the guide plate 251, in Figure 7 In the design, the central disc of the guide plate 251 is axially connected to a rotating ring 256 via a bearing. A fixed plate 2512 is located inside the central disc of the guide plate 251. A movable plate 2563 is located on one side of the rotating ring 256. An airbag 2564 is positioned between the fixed plate 2512 and the movable plate 2563. An inlet port 2511 is also provided at the central disc of the guide plate 251 for introducing an air guide tube 24 into the massage module 2, allowing it to inflate and deflate the airbag 2564. During the inflation of the airbag 2564, it pushes the movable plate 2563, causing the rotating ring 256 to rotate counterclockwise. Three connecting rods are equidistantly connected circumferentially around the central disc of the guide plate 251. The rod 2561 and each connecting rod 2561 are rotatably connected to the corresponding side of the tapping cylinder 254 through the push-pull rod 2562. During the rotation of the rotating ring 256, the connecting rod 2561 will drive the push-pull rod 2562 to apply a pushing force to the tapping cylinder 254, so that the three tapping cylinders 254 installed in the guide plate 251 expand outward synchronously. At the same time, a first return spring 255 is engaged between the side of the tapping cylinder 254 facing away from the push-pull rod 2562 and the inner wall of the rectangular arm end of the support plate 252. This is used to automatically retract the tapping cylinder 254 when the airbag 2564 is deflated, thereby jointly realizing the massage action of pushing and kneading. Furthermore, in order to achieve the function of the air bag 253 rotating during the sliding process of the striking cylinder 254, in Figure 7 and Figure 8 In this process, a support plate 252 is provided around the guide plate 251, and a toothed plate 2521 is installed on the side of the support plate 252 near the rectangular arm of the guide plate 251. A groove 2532 is provided at the axis of the annular support of the air bag 253. A retaining ring 2542 that matches the groove 2532 is provided at the top of the striking cylinder 254. A toothed ring 2533 that meshes with the toothed plate 2521 is also provided on the outside of the groove 2532 of the annular support of the air bag 253. During the sliding process of the striking cylinder 254 in the rectangular arm of the guide plate 251, the air bag 253 is forced to rotate around the mating point of the retaining ring 2542 and the groove 2532 due to the meshing of the toothed plate 2521 and the toothed ring 2533, thereby realizing the kneading action. It is worth noting that, in order to achieve the aforementioned tapping of the air bag 253 and thus achieve the tapping massage effect, in Figure 9In the striking cylinder 254, a telescopic rod 2544 extending through its bottom is vertically installed inside. A sealing ring 2543 is provided on the outer side of the bottom of the striking cylinder 254, and the inner wall of the sealing ring 2543 abuts against the surface of the telescopic rod 2544. A piston plate 2547 is provided on the outer side of the middle part of the telescopic rod 2544, and the piston plate 2547 and the inner wall of the striking cylinder 2544 form a sealed chamber. The striking plate 2546 is connected through the upper end of the telescopic rod 2544, and the upper surface of the striking plate 2546 abuts against the lower end of the annular support part of the air bag 253. An air extraction pipe 2545 is provided at the eccentric bottom of the striking cylinder 254, and the air extraction pipe 2545 is connected to the air extraction end of the air pump 23. A second return spring 2548 is sleeved on the outside of the telescopic rod 2544, and the telescopic rod 2544 is located at the piston plate 2544. A vent 2549 is provided on one side below 47. When the air pump 23 uses the air guide pipe 24 to evacuate the sealed chamber of the tapping cylinder 254 with the air extraction pipe 2545, the negative pressure in the sealed chamber will pull the telescopic rod 2544 with the piston plate 2547 downward and compress the second return spring 2548 until the vent 2549 on the telescopic rod 2544 is pulled to the outside of the sealing ring 2543. The air outside the sealed chamber will instantly break the vacuum and be completely reset under the action of the second return spring 2548, so that the tapping plate 2546 will quickly tap the air bag 253. The space between the tapping plate 2546 and the air bag 253 will be compressed, which will squeeze the air bag 253 and thus produce a rapid and strong tapping massage effect. The tapping speed and force can be adjusted by adjusting the air pump 23.

[0024] Its working principle is as follows: When the air pump 23 evacuates the sealed chamber through the air guide pipe 24 and the air extraction pipe 2545, a negative pressure is formed in the chamber. This pulls the piston plate 2547 and drives the telescopic rod 2544 to move downward, compressing the second return spring 2548. When the telescopic rod 2544 moves down until the air hole 2549 passes the sealing ring 2543, external air quickly enters the chamber, and the negative pressure is broken. Subsequently, under the restoring force of the second return spring 2548, the telescopic rod 2544 rapidly returns to its original position, causing the striking plate 2546 to violently strike the bottom of the air bag 253. During the striking process, the air between the striking plate 2546 and the air bag 253 is rapidly compressed and released, thereby generating an instantaneous impact force to simulate the effect of tapping massage.

[0025] The outer surface of the inflatable part of the air bag 253 is bonded with a pressure plate 2531. The pressure plate 2531 is a flat sheet or a protrusion with massage bumps, which is used to directly contact the human body and transmit massage force. The surface of the seat body 1 is covered with a surface covering 11. The surface covering 11 is made of soft materials such as leather or high-grade knitted fabric, which covers the surface of the pressure plate 2531 of the massage actuator 25. This not only avoids the massage actuator 25 from directly contacting the occupant, but also uses the elasticity and cushioning of the fabric to further improve comfort.

[0026] Working principle: Using air pump 23 as a power source, the PLC controller controls the solenoid valve group to precisely deliver or extract gas to each air passage in the massage module 2. The airflow mainly drives three types of actuators: First, by inflating the airbag 2564, the rotating ring 256 is driven to rotate. Then, through the linkage mechanism including the connecting rod 2561 and the push-pull rod 2562, the rotational motion is converted into the synchronous radial expansion and contraction of the three striking cylinders 254, thereby realizing the kneading action of pushing and pinching. Secondly, by rapidly pumping out the gas from the sealed chamber inside the striking cylinder 254, the negative pressure, in conjunction with the second return spring 2548, drives the telescopic rod 2544 and the striking plate 2546 to reciprocate at high speed, violently striking the air bag 253 to produce a striking effect. At the same time, the radial sliding of the striking cylinder 254 forces the air bag 253 to rotate through the rack and pinion plate 2521 gear ring 2533 mechanism, thus achieving the kneading action. Third, air is directly supplied to the airbag 253, causing it to expand and contract, thereby generating a pressing action. In conjunction with the above two sets of execution methods, the force applied to the flight attendant's body is adjusted to simulate a variety of professional massage techniques.

[0027] Compared to the current mainstream pneumatic massage seats, which offer a gentle massage experience but lack impact, this solution integrates a highly efficient mechanical impact structure, the striking plate 2546, and the telescopic rod 2544, into the pneumatic system. By rapidly drawing a vacuum with the air pump 23 and then releasing it instantly, it achieves a short, powerful, and impactful deep acupressure-style tapping massage that is difficult to achieve with traditional pneumatic solutions. This effectively avoids the shortcomings of insufficient massage intensity in existing products and effectively relieves muscle soreness after strenuous exercise and stiffness caused by long-term driving.

[0028] Meanwhile, this solution controls the air pump 23's air extraction rate through a program, enabling stepless adjustment of the tapping force and frequency. This provides users with a wide range of customizable massage experiences, from gentle and soothing to powerful and intense. While ensuring the safety and quietness of the pneumatic system, it achieves the powerful massage sensation of a motor-driven solution.

[0029] 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.
