[0047] The gas pump 23 is connected with the lower base plate 21 and the upper base plate 22 through the gas guide pipe 24 respectively, and the flow direction is controlled through the electromagnetic valve, so as to drive the massage actuators 25 to perform kneading and tapping massage actions;

[0048] It is worth noting that, as shown in Figures 5-6 The massage actuators 25 comprise a guide plate 251 and three tapping cylinders 254, the guide plate 251 has a center disc and three rectangular arms extending equidistantly from the center disc in the circumferential direction, a sliding groove is arranged on each rectangular arm, the tapping cylinders 254 are slidably arranged in each rectangular arm through the guide plates 2541 matched with the sliding grooves on both sides of the tapping cylinders 254, and can be driven to synchronously expand and contract;

[0049] And, the end of each tapping cylinder 254 is provided with a gas bag 253, the gas bag 253 has an annular supporting part and an inflation part, and the gas bag 253 rotates during the sliding of the tapping cylinder 254; a tapping plate 2546 is further arranged in the tapping cylinder 254, for tapping the gas bag 253 to produce tapping effect.

[0050] In order to realize the sliding of the tapping cylinder 254 in the rectangular arm of the guide plate 251, a Figure 7In the middle, the center disc of the guide plate 251 is connected with a rotating ring 256 through a bearing in the axial direction, the inner side of the center disc of the guide plate 251 is provided with a fixed plate 2512, one side of the rotating ring 256 is provided with a movable plate 2563, and the gas bag 2564 is arranged between the fixed plate 2512 and the movable plate 2563. An introduction pipe opening 2511 is arranged at the center disc of the guide plate 251, which is used to introduce the air duct 24 into the massage module 2, so as to inflate and deflate the gas bag 2564. In the inflation and expansion process of the gas bag 2564, the movable plate 2563 is pushed to make the rotating ring 256 rotate counterclockwise. Three connecting rods 2561 are connected on the center disc of the guide plate 251 at equal intervals in the circumferential direction, and each connecting rod 2561 is connected with the percussion cylinder 254 on the corresponding side through a push-pull rod 2562. In the rotating process of the rotating ring 256, the push-pull rod 2562 is driven by the connecting rod 2561 to apply a pushing force to the percussion cylinder 254, so that the three percussion cylinders 254 installed in the guide plate 251 are expanded outward synchronously. At the same time, the first reset spring 255 is arranged between the side of the percussion cylinder 254 away from the push-pull rod 2562 and the inner wall of the end of the rectangular arm of the support plate 252, which is used to automatically retract the percussion cylinder 254 in cooperation with the first reset spring 255 when the gas bag 2564 is deflated, so as to realize the massage action of pushing and pinching together.

[0051] Further, in order to realize the self-rotation function of the gas bag 253 in the sliding process of the percussion cylinder 254, Figure 7 and Figure 8 In the middle, the surrounding of the guide plate 251 is provided with a support plate 252, and the side of the rectangular arm of the support plate 252 close to the guide plate 251 is provided with a toothed plate 2521. The axis of the annular support part of the gas bag 253 is provided with a clamping groove 2532, the top of the percussion cylinder 254 is provided with a clamping ring 2542 matched with the clamping groove 2532, and the outer side of the clamping groove 2532 of the annular support part of the gas bag 253 is further provided with a toothed ring 2533 engaged with the toothed plate 2521. In the sliding process of the percussion cylinder 254 in the rectangular arm of the guide plate 251, the gas bag 253 is forced to rotate around the matching point of the clamping ring 2542 and the clamping groove 2532 through the engagement of the toothed plate 2521 and the toothed ring 2533, so as to realize the rubbing action.

[0052] It is worth noting that in order to realize the above-mentioned percussion of the gas bag 253, and then realize the percussion massage effect, Figure 9In the embodiment, the inside of the percussion cylinder 254 is vertically installed with a telescopic rod 2544 penetrating through the bottom thereof, and the bottom outside of the percussion cylinder 254 is provided with a sealing rubber ring 2543, the inner wall of which is in abutment with the surface of the telescopic rod 2544, the middle outside of the telescopic rod 2544 is provided with a piston sheet 2547, which, together with the inner wall of the percussion cylinder 254, forms a closed chamber, the percussion plate 2546 is connected through the upper end of the telescopic rod 2544, the upper surface of the percussion plate 2546 is in abutment with the lower end of the annular support part of the air bag 253, the eccentric bottom of the percussion cylinder 254 is provided with an air extraction pipe 2545 connected with the air extraction end of the air pump 23, the outside of the telescopic rod 2544 is sleeved with a second reset spring 2548, and the telescopic rod 2544 is provided with an air hole 2549 at one side below the piston sheet 2547, when the air pump 23 performs air extraction operation on the closed chamber of the percussion cylinder 254 with the air extraction pipe 2545, the negative pressure in the closed chamber drags the telescopic rod 2544 with the piston sheet 2547 downwards and compresses the second reset spring 2548, until the air hole 2549 on the telescopic rod 2544 is dragged to the outside of the sealing rubber ring 2543, the air outside the closed chamber breaks the vacuum instantaneously, and is completely reset under the action of the second reset spring 2548, so that the percussion plate 2546 rapidly hits the air bag 253, the space between the percussion plate 2546 and the air bag 253 is compressed to generate extrusion on the air bag 253, thereby generating rapid and strong percussion massage effect, and the speed and intensity of percussion can be adjusted by adjusting the air extraction rate of the air pump 23.

[0053] The working principle is that when the air pump 23 performs air extraction on the closed chamber through the air guide pipe 24 and the air extraction pipe 2545, negative pressure is formed in the chamber to pull the piston sheet 2547 and the telescopic rod 2544 downwards to compress the second reset spring 2548, when the telescopic rod 2544 moves downwards to make the air hole 2549 thereon pass the sealing rubber ring 2543, external air rapidly enters the chamber to break the negative pressure; subsequently, under the restoring force of the second reset spring 2548, the telescopic rod 2544 is rapidly reset upwards to drive the percussion plate 2546 to violently hit the bottom of the air bag 253, during the hitting process, the air between the percussion plate 2546 and the air bag 253 is rapidly compressed and released, thereby generating instantaneous impact force to simulate percussion massage effect.

[0054] The outer surface of the inflation part of the air bag 253 is bonded with a pressing plate 2531, which is a flat sheet or a convex shape with massage convex points, used for direct contact with the human body and transmitting massage force. The surface of the seat body 1 is covered with a surface coating 11 made of soft materials such as leather or high-grade knitted fabric, covering the surface of the pressing plate 2531 of the massage executor 25, avoiding direct contact between the massage executor 25 and the passenger, and further improving comfort by the elasticity and cushioning of the fabric.

[0055] Working principle: Using air pump 23 as power source, the electromagnetic valve group is controlled by PLC controller to accurately deliver or exhaust gas to each air path in the massage module 2, and the airflow mainly drives three kinds of executive mechanism:

[0056] First, by inflating the air bag 2564, the rotating ring 256 is pushed to rotate, and then the connecting rod mechanism including connecting rod 2561 and push-pull rod 2562 converts the rotary motion into the synchronous radial expansion and contraction of the three percussion cylinders 254, realizing the kneading action of pushing and pinching;

[0057] Second, by rapidly exhausting the gas in the closed chamber inside the percussion cylinder 254, the negative pressure cooperates with the second return spring 2548 to drive the telescopic rod 2544 and the percussion plate 2546 to move back and forth at high speed, which produces a violent beating effect on the air bag 253. At the same time, the radial sliding of the percussion cylinder 254 will force the air bag 253 to rotate through the rack and pinion mechanism of rack and pinion 2521 and gear ring 2533, realizing the kneading action;

[0058] Third, directly supplying air to the air bag 253 to make it expand and contract, thereby producing a pressing action, and adjusting the force acting on the passenger's body in cooperation with the above two groups of execution modes to simulate a variety of professional massage techniques.

[0059] Compared with the current mainstream pneumatic massage seat, which has a soft massage feeling and lacks impact force, the present scheme combines the efficient mechanical impact structure of percussion plate 2546 and telescopic rod 2544 in the pneumatic system, and realizes the short, strong and impact deep layer percussive massage that the traditional pneumatic scheme cannot achieve through the way of rapid vacuumization and instantaneous release of air pump 23, effectively avoiding the shortcomings of insufficient massage force of existing products, and effectively relieving the problem of muscle soreness after intense exercise and body stiffness caused by long-time driving.

[0060] At the same time, by controlling the air pump 23 exhaust rate through the program, the present scheme can steplessly adjust the intensity and frequency of percussion, providing users with a wide range of customizable massage experience from gentle and soothing to strong and powerful, while ensuring the safety and quietness of the pneumatic system, and realizing the strong massage feeling of the motor-driven scheme.

[0061] The above merely describes preferred embodiments of the present application, and is not used to limit the present application, any modification, equivalent replacement and improvement within the spirit and principle of the present application should be included in the protection scope of the present application.
