Description

Technical Field

[0001] The present invention belongs to the field of automotive massage seats, and more specifically, relates to a massage mechanism for automotive seats and home massage chairs. Background Art

[0002] With the improvement of people's living standards and the development of automotive technology, people's requirements for the comfort of automotive seats are also getting higher and higher. Car seats have evolved from a simple component to a relatively complex and highly precise component. The functions of automotive seats have gradually expanded and are no longer limited to providing a good driving and sitting posture.

[0003] When automotive seats and home massage chairs are used for a long time, they are likely to cause fatigue to the users. Currently, the massage seats on the market generally adopt a pushing massage method of pure airbag linear reciprocating motion. This massage mode has obvious deficiencies. Not only is the massage effect weak, but also the massage techniques are single, making it difficult to meet the user's demand for a comfortable massage experience. Another common type is the mechanical rotary massage method where the massage heads are lifted and lowered by a worm mechanism. Such massage heads rely on the worm mechanism for driving. When sudden situations such as vehicle collisions occur, the massage heads need to execute a reset operation through an electronic control command and cannot achieve instant reset. In this case, if the driver is injured and is squeezed by the massage heads for a long time, it is very likely to cause further harm, presenting a relatively large potential safety hazard.

[0004] Therefore, a massage mechanism for automotive seats and home massage chairs is proposed to solve the above drawbacks. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a massage mechanism for automotive seats and home massage chairs.

[0006] To solve the above technical problem, the basic concept of the technical solution adopted by the present invention is as follows:

[0007] A massage mechanism for automotive seats and home massage chairs includes an upper cover and a lower cover that is snap-fitted with the upper cover, and a massage head group is arranged between the upper cover and the lower cover;

[0008] The massage head group includes a massage cover, a massage ring is arranged on the massage cover, two bearings are arranged on the massage ring, massage heads are arranged on the bearings, the massage heads are rotatably fitted in the massage cover, and two springs are sleeved outside the massage ring.

[0009] Optionally, a motor is arranged inside the lower cover, output shafts are arranged at both output ends of the motor, and threads are arranged on the output shafts.

[0010] Optionally, a dental brace is provided between the upper cover and the lower cover, and a toothed ring meshing with the thread is provided on the dental brace.

[0011] Optionally, the massage ring is movably arranged in the dental brace. A rib axial positioning groove is arranged in the dental brace, and a rib axial positioning protrusion is arranged on the massage ring. The rib axial positioning protrusion is clamped in the rib axial positioning groove.

[0012] Optionally, a first wear-resistant ring is provided between the massage head group and the lower cover, and a second wear-resistant ring is provided between the massage head group and the upper cover.

[0013] Optionally, an air bag is arranged in the massage ring. The bottom of the air bag penetrates through the lower cover, and a wear-resistant piece is installed between the air bag and the massage ring by screws.

[0014] Optionally, a plurality of through holes are formed in the lower cover, and first screws are arranged in the through holes. A plurality of first threaded holes are formed in the upper cover, and one end of the first screw is threadedly engaged in the first threaded hole.

[0015] Optionally, a second through hole is formed in the massage cover, and a second screw is arranged in the second through hole. A second threaded hole is formed in the massage ring, and one end of the second screw is threadedly engaged in the second threaded hole.

[0016] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all the advantages described below at the same time:

[0017] The massage ring in the massage head group is provided with rotatable massage heads installed by two bearings, and two springs sleeved on the outside thereof provide elastic support. When the motor and the dental brace are started, the thread of the motor output shaft meshes with the toothed ring of the dental brace, driving the dental brace to rotate circumferentially. Since the rib axial positioning protrusion on the outside of the massage ring is inserted into the rib axial positioning groove on the inner side of the dental brace, while the massage head group revolves with the dental brace, it can move up and down in the vertical direction under the restriction of axial positioning, enabling the massage heads to form a composite movement trajectory of "rotation + reciprocating pressing", reducing the limitations of the massage modes of air bag extrusion or single mechanical rotation, and realizing diversified massage techniques such as kneading and pounding.

[0018] The bottom of the airbag arranged inside the massage ring penetrates through the lower cover, and a wear-resistant piece is fixed between it and the massage ring by a second screw, which can reduce the friction loss during the inflation and deflation process. During normal operation, the air pressure force generated by the inflation and expansion of the airbag overcomes the elastic force of the spring, pushing the massage head group to rise and contact the human body. When an emergency such as a vehicle collision occurs, the airbag quickly deflates through the conventional pump valve control system. The massage head group that loses the air pressure support is instantly reset under the action of the elastic restoring force of the spring, reducing the continuous extrusion of the massage head on the driver and passengers, and reducing the delay problem that the existing worm-driven massage head needs an electric control instruction to reset, improving the safety performance;

[0019] The first wear-resistant ring and the second wear-resistant ring respectively arranged between the massage head group and the lower cover and the upper cover can reduce the friction loss when the components move relative to each other. The rib positioning structure of the tooth sleeve and the massage ring not only ensures the movement guidance, but also realizes the axial rotation limit through the anti-rotation design at the semi-circular part of the spring, making the whole mechanism maintain stability during the compound movement, taking into account both the massage effect and the service life.

[0029] It should be noted that these drawings and textual descriptions are not intended to limit the scope of the concept of the present invention in any way, but rather to illustrate the concept of the present invention to those skilled in the art by reference to specific embodiments. Specific embodiments

[0030] The present invention will now be further described in detail with reference to the accompanying drawings.

[0031] Please refer to Figures 1-5 As shown, in this embodiment, a massage mechanism for an automotive seat and a household massage chair is provided, which includes an upper cover 1 and a lower cover 2 that is snap-fitted with the upper cover 1. A massage head group 14 is arranged between the upper cover 1 and the lower cover 2;

[0032] The massage head group 14 includes a massage cover 1402. A massage ring 1401 is arranged on the massage cover 1402. Two bearings 1403 are arranged on the massage ring 1401. A massage head 1404 is arranged on the bearings 1403. The massage head 1404 is rotatably fitted in the massage cover 1402. Two springs 11 are sleeved outside the massage ring 1401. The two springs 11 have stronger spring force, and at the same time, the axial rotation limit is also stopped by the semi-circular part of the spring 11.

[0033] Specifically, during the massage operation, the airbag 7 is inflated and expanded through a conventional pump valve. The air pressure force generated by it overcomes the elastic force of the two springs 11 sleeved outside the massage ring 1401, and pushes the whole massage head group 14 to rise; at the same time, the motor 6 in the lower cover 2 starts to rotate, and the output shafts at its two output ends rotate accordingly. The threads on the output shafts are engaged with the tooth rings on the tooth sleeves 13 arranged between the upper cover 1 and the lower cover 2, driving the tooth sleeves 13 to perform circumferential rotation. Since the rib axial positioning protrusions outside the massage ring 1401 are clamped in the rib axial positioning grooves inside the tooth sleeves 13, this positioning structure enables the massage ring 1401 to only move up and down in the vertical direction under the axial positioning restriction while making a revolution movement along with the tooth sleeves 13, thereby driving the massage head group 14 to achieve a compound movement of "circumferential rotation + axial reciprocation";

[0034] Specifically, the massage ring 1401 in the massage head group 14 is provided with a massage head 1404 through a bearing 1403. The massage head 1404 can be freely rotatably fitted in the massage cover 1402. When the massage ring 1401 makes a revolution and moves up and down along with the tooth sleeve 13, the massage head 1404, on the one hand, makes a revolution and lifting movement along with the whole structure, and on the other hand, realizes self-rotation through the bearing 1403, thereby generating a compound massage effect of rotational pressing and reciprocating pushing on the human body. In addition, the first wear-resistant ring 9 between the massage head group 14 and the lower cover 2 and the second wear-resistant ring 12 between the massage head group 14 and the upper cover 1 can reduce the frictional loss between components and extend the service life of the mechanism;

[0035] When the massage stops, the airbag 7 is controlled to deflate through the pump valve system, the internal air pressure drops, and the abutting force against the spring 11 is lost. At this time, the two springs 11 push the massage head group 14 downward to reset by virtue of their elastic restoring forces. The bottom of the airbag 7 penetrates through the lower cover 2, and the wear-resistant sheet 8 fixedly installed between it and the massage ring 1401 through the second screw 1405 can reduce friction during the inflation and deflation of the airbag 7, ensuring smooth movement. The inflation and deflation control of the airbag 7 is realized by a conventional pump valve system, and the specific control circuit or structure will not be elaborated here.

[0036] As Figures 1-5 shown, a motor 6 is arranged inside the lower cover 2 of this embodiment. Output shafts are arranged at both output ends of the motor 6, threads are arranged on the output shafts, a dental sleeve 13 is arranged between the upper cover 1 and the lower cover 2, a gear ring meshing with the threads is arranged on the dental sleeve 13, the massage ring 1401 is movably arranged inside the dental sleeve 13, a rib axial positioning groove is arranged inside the dental sleeve 13, a rib axial positioning protrusion is arranged on the massage ring 1401, and the rib axial positioning protrusion is clamped in the rib axial positioning groove. A first wear-resistant ring 9 is arranged between the massage head group 14 and the lower cover 2, a second wear-resistant ring 12 is arranged between the massage head group 14 and the upper cover 1, an airbag 7 is arranged inside the massage ring 1401, the bottom of the airbag 7 penetrates through the lower cover 2, a wear-resistant sheet 8 is installed between the airbag 7 and the massage ring 1401 with screws, a plurality of through holes 3 are opened on the lower cover 2, first screws 5 are arranged inside the through holes 3, a plurality of first threaded holes 4 are opened on the upper cover 1, one end of the first screw 5 is in threaded fit inside the first threaded hole 4, a second through hole is opened on the massage cover 1402, a second screw 1405 is arranged inside the second through hole, a second threaded hole is opened on the massage ring 1401, and one end of the second screw 1405 is in threaded fit inside the second threaded hole.

[0037] The massage ring 1401 inside the massage head group 14 is installed with rotatable massage heads 1404 through two bearings 1403, and two springs 11 sleeved on the outside thereof provide elastic support. When the motor 6 and the dental sleeve 13 are started, the threads of the output shaft of the motor 6 mesh with the gear ring of the dental sleeve 13, driving the dental sleeve 13 to rotate circumferentially. Since the rib axial positioning protrusions on the outside of the massage ring 1401 are inserted into the rib axial positioning grooves on the inside of the dental sleeve 13, while the massage head group 14 revolves with the dental sleeve 13, it can move up and down in the vertical direction under the limitation of axial positioning, enabling the massage heads 1404 to form a composite movement track of "rotation + reciprocating pressing", reducing the limitations of the massage modes of pushing by the airbag 7 or single mechanical rotation, and realizing diversified massage techniques such as kneading and pounding;

[0038] The airbag 7 provided inside the massage ring 1401 penetrates through the bottom of the lower cover 2. A wear-resistant piece 8 is fixed between it and the massage ring 1401 through a second screw 1405, which can reduce the frictional loss during the inflation and deflation process. During normal operation, the air pressure force generated by the inflation and expansion of the airbag 7 overcomes the elastic force of the spring 11, pushing the massage head group 14 to rise and contact the human body. When an emergency such as a vehicle collision occurs, the airbag 7 quickly deflates through the conventional pump valve control system. The massage head group 14 that loses the air pressure support is instantly reset under the action of the elastic restoring force of the spring 11, reducing the continuous extrusion of the massage head 1404 on the driver and passengers, and reducing the delay problem that the existing worm-driven massage head needs an electric control command to reset, improving the safety performance;

[0039] The first wear-resistant ring 9 and the second wear-resistant ring 12 respectively provided between the massage head group 14 and the lower cover 2 and the upper cover 1 can reduce the frictional loss during the relative movement of the components. The rib positioning structure of the dental brace 13 and the massage ring 1401 not only ensures the movement guidance, but also realizes the axial rotation limit through the anti-rotation design at the semi-circular part of the spring 11, enabling the entire mechanism to maintain stability during the compound movement, taking into account both the massage effect and the service life.
