Description

Technical Field

[0001] The invention relates to a car seat massager mechanism, in particular to a car seat massager mechanism, and belongs to the technical field of car seat massage devices. Background Art

[0002] A car seat massage device is a car seat with a built-in massage function. A massage seat can relieve physical fatigue and stress, and improve the comfort and safety of drivers and passengers. Car seat massage control devices can be divided into two types according to the design method: mechanical and pneumatic. The more popular ones on the market now are pneumatic massage seats, which use components such as air pressure regulators, cylinders, air pumps, and solenoid valves. They must also be equipped with a complete software control system, which results in an overly complex structure. After long-term use, the air tightness of the solenoid valve and the air supply pipeline will gradually decrease, and there will be problems such as difficult maintenance and low reliability.

[0021] The present invention has at least the following beneficial effects:

[0022] 1. The car seat massager mechanism has a highly efficient massage effect. It can realize the massage function of the seat by driving the turntable and the subsequent connecting rod, swing arm and push arm to alternately reciprocate. This mechanical transmission method ensures the continuity and stability of the massage action and provides effective muscle relaxation and blood circulation promotion.

[0023] 2. The car seat massager mechanism adjusts the swing amplitude of the first swing arm by telescoping the electric push rod, thereby adjusting the reciprocating distance and massage intensity of the push arm, allowing the user to adjust the intensity and frequency of the massage according to personal preferences and needs, thereby improving the comfort and personalization of use.

[0024] 3. The car seat massager mechanism adjusts the push arm through the adjustment structure. When the swing amplitude of the push arm increases, not only the massage intensity is increased, but also the deformation of the spring that cooperates with the push arm and the push plate drives the reciprocating motion of the second piston. This movement continuously changes the chamber pressure, and cooperates with the opening and closing of the valve plate to realize the automatic extraction and delivery of the lubricating oil in the oil storage tank. The lubricating oil is finally discharged into the limit groove through the delivery pipe, the three-way pipe and the storage tank to lubricate the push arm. This automatic lubrication mechanism effectively reduces friction and wear, extends the service life of the equipment, and at the same time improves the stability and reliability of the reciprocating motion of the push arm.

[0025] 4. The car seat massager mechanism reduces the need for manual lubrication and the complexity and frequency of maintenance by automating the lubrication system. Users do not need to check or add lubricating oil frequently, thus saving time and energy. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0036] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0037] like Figure 1 - Figure 7 As shown, the car seat massager mechanism provided in this embodiment includes a car seat massager composed of a first mounting frame 1, a second mounting frame 2, a massage mechanism 3, a drive mechanism 4 and an abutment plate 5; the first mounting frame 1 and the second mounting frame 2 are used to support or fix other components, and the massager mechanism can be compactly integrated inside the car seat. Figure 2 As shown, the massage mechanism 3 includes a sleeve 301 arranged on the first mounting frame 1, a first piston 303 reciprocatingly arranged inside the sleeve 301, an airbag 302 fixedly mounted on one end of the sleeve 301, a push rod 304 fixedly connected to the outer surface of the first piston 303 and passing through the sleeve 301 and the first mounting frame 1, a connecting block 305 welded to the other end of the push rod 304, and a return spring 306 fixedly mounted on the connecting block 305 near the push rod 304; the sleeve 301 is hollow inside, and a mounting piece 307 fixed to the outer surface of the first mounting frame 1 is welded at one end of the sleeve 301 away from the airbag 302, the connecting block 305 is bolted to the abutment plate 5, the return spring 306 surrounds the outer surface of the push rod 304, and the end of the return spring 306 away from the connecting block 305 is fixed to the outer surface of the first mounting frame 1.

[0038] In this embodiment, in order to realize the driving of the massage mechanism 3, as shown in FIG. Figure 1 , Figure 3 - Figure 7As shown, the driving mechanism 4 includes a driving motor 401 fixedly arranged outside the second mounting frame 2, a rotating disk 402 fixed on the output shaft of the driving motor 401, a pushing arm 403 slidably arranged on the top side of the second mounting frame 2 and connected to the abutment plate 5, a connecting piece hingedly installed between the pushing arm 403 and the rotating disk 402, and an adjusting structure 407 hingedly installed outside the second mounting frame 2 for adjusting the connecting piece; wherein, the number of the abutment plate 5 and the pushing arm 403 are both two, and a connecting structure 406 is installed between the two pushing arms 403; the number of the massage mechanisms 3 is several and they are symmetrically arranged in two groups, and the two groups of massage mechanisms 3 correspond to the two abutment plates 5 respectively. When the driving mechanism 4 is working, the driving push rod 304 reciprocates inside the sleeve 301, so that the first piston 303 moves inside the sleeve 301, thereby compressing or releasing the gas in the sleeve 301. When the gas is compressed, it is forced into the airbag 302, causing the airbag 302 to expand and produce a massage effect.

[0039] In addition, the return spring 306 provides elastic force when the push rod 304 moves in the reverse direction, helping the first piston 303 to return to the initial position, thereby achieving a continuous massage action.

[0040] Specifically, Figure 6 As shown, the front and back sides of the second mounting frame 2 are provided with limit slots 21, and the outer surfaces of the two push arms 403 are fixed with guide blocks 4031 that slide with the limit slots 21. The limit slots 21 provided on the front and back sides of the second mounting frame 2 slide with the guide blocks 4031 on the outer surfaces of the push arms 403, ensuring the stability and accuracy of the push arms 403 during the reciprocating motion, reducing shaking and deviation during the motion, and making the massage action more stable and controllable. The connecting member is composed of a first swing arm 404 and a connecting rod 405 that are hingedly connected. The other end of the first swing arm 404 is hinged to the outer surface of the front push arm 403, and the other end of the connecting rod 405 is hinged to the outer surface of the turntable 402. Figure 1 As shown, the connection structure 406 includes a second swing arm 4061 and two connecting shafts 4062, so that the two push arms 403 can achieve coordinated linkage through the second swing arm 4061. When the front push arm 403 moves, it will drive the second swing arm 4061 to move through the connecting shaft 4062, thereby causing the other push arm 403 to move accordingly. This linkage effect ensures the continuity and uniformity of the massage action. The second swing arm 4061 is located directly above the two push arms 403, and the two ends of the two connecting shafts 4062 are respectively connected and fixed to the upper surfaces of the two push arms 403 and the lower surfaces of the two ends of the second swing arm 4061.

[0041] like Figure 3 and Figure 5As shown, the adjustment structure 407 includes two adjustment arms 4071 and an electric push rod 4072. The two adjustment arms 4071 are hingedly mounted on the front and back of the second mounting frame 2, and the electric push rod 4072 is hingedly mounted on the outside of the second mounting frame 2, and the output end of the electric push rod 4072 is hingedly connected to the two adjustment arms 4071. The user is allowed to adjust the position of the adjustment arm 4071 by extending and retracting the electric push rod 4072, thereby changing the swing amplitude of the push arm 403. This adjustment mechanism allows the user to adjust the intensity and frequency of the massage according to personal preferences and needs, thereby improving the comfort and personalization of use.

[0042] It should be noted that an arc-shaped adjusting slot 4073 is provided inside the first swing arm 404, and a limit slide shaft 4074 penetrating the adjusting slot 4073 is rotatably installed at the top of the two adjusting arms 4071. The adjusting slot 4073 provided inside the first swing arm 404 cooperates with the limit slide shafts 4074 at the top of the two adjusting arms 4071 to ensure stability and accuracy during the adjustment process. This design prevents the adjustment arm 4071 from deflecting or shaking during the adjustment process, making the adjustment of the massage intensity more accurate and reliable.

[0043] In this embodiment, in order to ensure the stable movement of the push arm 403, as shown in FIG. Figure 1 , Figure 5 , Figure 6 and Figure 8 As shown, the outer surface of the second mounting frame 2 is provided with a lubricating mechanism 6 for lubricating the push arm 403, and the lubricating mechanism 6 includes a pump housing 602 and an oil storage tank 608 fixedly arranged outside the second mounting frame 2, a second piston 603 arranged inside the pump housing 602, two check valves 605 fixedly connected to the outer surface of the pump housing 602, a valve plate 606 elastically hingedly installed inside the two check valves 605, and a connecting structure fixedly connected to the two check valves 605. The two check valves 605 and the valve plates 606 inside them ensure the unidirectional flow of the lubricating oil and prevent the backflow of the lubricating oil during the pumping process. This design improves the lubrication efficiency and ensures that the lubricating oil can be accurately delivered to the part that needs lubrication. The pump housing 602 is provided with a pump cavity inside, and the second piston 603 is reciprocatingly arranged in the pump cavity. Through the reciprocating motion of the second piston 603 in the pump cavity, the pump housing 602 can pump the lubricating oil in the oil storage tank 608 into the limit groove 21. The automatic lubrication mechanism reduces the need for manual lubrication and improves the convenience of use. The outer surface of the second piston 603 is fixedly mounted with a valve stem 604 extending to the outside of the pump housing 602, and the other end of the valve stem 604 is bolted with a push plate 607. Figure 1As shown, the top end of the push plate 607 corresponds to the right end of the front push arm 403. The front push arm 403 adjusts the sliding distance by adjusting the first swing arm 404 using the adjustment structure 407. After the front push arm 403 is adjusted, its right end is against the outer surface of the top end of the push plate 607. The outer surface of the second mounting frame 2 is bolted with a mounting platform 601 for fixing the pump housing 602 and the oil storage tank 608.

[0044] Specifically, Figure 8 As shown, the connecting structure is composed of two delivery pipes 609 and a three-way pipe 610. A storage groove 611 connected to the limit groove 21 is provided inside the second mounting frame 2. The two ends of the three-way pipe 610 are connected to the limit groove 21. The two delivery pipes 609 are respectively fixedly connected to the ends of the two check valves 605, and the two delivery pipes 609 are respectively fixedly connected to the oil storage tank 608 and the three-way pipe 610. Among them, the top delivery pipe 609 is a hose. An excess lubricating oil storage tank can also be set in the limit groove 21 to better perform lubrication work. It should be noted that a spring surrounding the outer surface of the valve stem 604 is fixedly installed between the push plate 607 and the pump housing 602.

[0045] When this embodiment is in use, the lubrication mechanism 6 reduces the friction between the push arm 403 and the limit groove 21 by providing lubricating oil into the limit groove 21, thereby improving the smoothness and accuracy of the movement of the push arm 403, helping to extend the service life of the mechanism and reduce the noise generated by friction.

[0046] In addition, when the swing amplitude of the push arm 403 increases, not only the massage intensity is increased, but also the reciprocating motion of the second piston 603 is driven by the deformation of the spring that cooperates with the push arm 403 and the push plate 607. This movement continuously changes the chamber pressure, and cooperates with the opening and closing of the valve plate 606 to realize the automatic extraction and delivery of the lubricating oil in the oil storage tank 608. The lubricating oil is finally discharged into the limit groove 21 through the delivery pipe 609, the three-way pipe 610 and the storage groove 611 to lubricate the push arm 403. This automatic lubrication mechanism effectively reduces friction and wear, extends the service life of the equipment, and at the same time improves the stability and reliability of the reciprocating motion of the push arm 403.

[0047] like Figure 1 - Figure 8As shown, the principle of the car seat massager mechanism provided by this embodiment is as follows: when the present invention is used, the rotating disk 402 is driven by the driving motor 401, and the rotating disk 402 rotates through the connecting rod 405 and the first swing arm 404 to drive the front push arm 403 to move, and when the front push arm 403 moves, it drives another push arm 403 to move through the connecting structure 406, so that the two push arms 403 alternately reciprocate, and when the push arms 403 alternately reciprocate, they squeeze the two groups of first pistons 303, and the first pistons 303 move inside the sleeve 301 and push the gas in the sleeve 301, thereby agitating the airbag 302 to inflate, so as to achieve the function of seat massage;

[0048] When the massage effect needs to be adjusted, the electric push rod 4072 is extended and retracted to drive the adjustment arm 4071 to swing, and the limiting slide shaft 4074 slides in the adjustment slide groove 4073 to drive the first swing arm 404 to rotate, thereby adjusting the swing amplitude of the push arm 403. When the amplitude adjustment of the push arm 403 increases, the reciprocating distance of the push arm 403 will also increase, and then the push arm 403 and the push plate 607 will be against each other to cooperate with the deformation of the spring, driving the second piston 603 to reciprocate. The reciprocating motion of the second piston 603 continuously changes the chamber pressure, and cooperates with the opening and closing of the two valve plates 606 to extract the lubricant in the oil storage tank 608 and transport it through the delivery pipe 609 and the three-way pipe 610, and finally discharged into the limiting groove 21 through the storage groove 611, so as to realize the lubrication of the push arm 403 and improve the reciprocating stability of the push arm 403.
