Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically to an insurance mechanism, a massage mechanism, and a seat. Background Technology

[0002] In car seats, linear actuators drive certain components that come into contact with the human body, such as massage heads. However, because linear actuators have a self-locking function, the components driven by the linear actuators can cause injury to the human body in the event of a collision. Therefore, some seats are now equipped with a crumple zone structure. The crumple zone structure is connected to the linear actuator (the core drive component of the push-out mechanism assembly). When subjected to a large impact, the linear actuator can automatically crumple to prevent the components driven by the linear actuator from causing injury to the human body.

[0003] Currently, a safety mechanism includes a linear actuator, a mounting assembly, and a collapse assembly. The mounting assembly includes a mounting base and a movable base, with the movable base sliding within the mounting base. The collapse assembly includes a cylindrical spring and two clamping plates. The cylindrical spring is positioned above the safety bar, with both ends connected to one end of each clamping plate. The other end of each clamping plate rotates within the mounting base. The fixed end of the linear actuator is fixedly connected to the movable base, and the output end of the linear actuator is connected to the safety bar. The safety bar and the clamping plates abut against each other. When an external moving part (e.g., a massage head) is impacted by an external force, the linear actuator locks internally, the movable base moves, the two clamping plates are pushed apart by the safety bar, and the cylindrical spring is stretched, thereby achieving overall collapse of the linear actuator.

[0004] However, the aforementioned crumple zone assembly, with its cylindrical spring positioned above the bumper, occupies a significant amount of longitudinal space, resulting in a thicker seat. Utility Model Content

[0005] (a) The problem to be solved by this utility model is that the cylindrical spring is located above the bumper and occupies a large longitudinal space, resulting in a thicker seat.

[0006] (II) Technical Solution This utility model provides an insurance mechanism, which includes an elastic element, a base, a limiting element, and two clamping structures. The elastic element is provided on one side of the base, and the clamping structure is symmetrically rotatably connected to the other side. The elastic member has two abutting portions, which are located between the two clamping structures. Each abutting portion corresponds to one of the clamping structures and contacts the clamping structure. A limiting area for limiting the safety bar is formed between the limiting member and the two clamping structures.

[0007] According to one embodiment of the present invention, the elastic element includes a torsion spring and a connecting post; The connecting post is connected to the base, and the torsion spring is sleeved on the connecting post. The torsion spring has two abutting parts.

[0008] According to one embodiment of the present invention, the clamping structure includes an abutment plate and a limiting plate connected to each other; The abutting plate and the abutting part correspond one-to-one, and the abutting plate abuts against the abutting part; The limiting plate has a limiting protrusion on the side away from the abutment plate, and the two limiting protrusions cooperate to restrict the movement of the bumper in the second direction.

[0009] According to one embodiment of the present invention, the limiting plate is rotatably connected to the base via a rotating member.

[0010] According to one embodiment of the present invention, both ends of the limiting member are respectively connected to the base through a rotating member; The limiting member is used to restrict the movement of the bumper along a first direction, which is opposite to the second direction.

[0011] According to one embodiment of the present invention, the limiting member includes a top plate and a vertical plate connected together. The top plate and the base cooperate to limit the movement of the bumper along the third direction, which is perpendicular to the second direction. The base has a through hole, one end of the vertical plate is inserted into the through hole and the side wall of the vertical plate is in contact with the side wall of the through hole.

[0012] According to one embodiment of the present invention, the rotating component includes a first washer and a second washer, the first washer being disposed between the top plate and the limiting plate, and the second washer being disposed between the limiting plate and the base.

[0013] According to one embodiment of the present invention, the base includes a first plate and a second plate connected to each other, the second plate being in the shape of a "Z".

[0014] A massage mechanism includes a safety mechanism, and further includes a push mechanism assembly, a tapping mechanism assembly, a safety lever, a movable seat, and a base frame; The output end of the ejection mechanism assembly is connected to the safety bar. The fixed end of the ejection mechanism assembly and the fixed end of the striking mechanism assembly are both connected to the movable seat; The movable seat is slidably connected to the base frame; The base is connected to the frame.

[0015] A type of seat, including an insurance mechanism, or including a massage mechanism.

[0016] The beneficial effects of this utility model are: When the massage head extends or retracts normally, the safety bar is located within the limiting zone. When subjected to a large external force impact, the safety bar moves in the second direction, squeezing the two clamping structures apart. At this time, the two clamping structures rotate, and one end of the two clamping structures and the abutment part approaches each other, transmitting the force to the elastic element. The elastic element undergoes elastic deformation, and the safety bar exits the limiting zone. The push-out mechanism assembly can then collapse as a whole, buffering the impact from the external force.

[0017] Because the elastic element is located on one side of the limiting area, rather than above it, the longitudinal space in that area can be reduced, thus reducing the longitudinal space required by the massage chair. The overall thickness of the seat is thinner, making it suitable for more car models and improving its practicality. Attached Figure Description

[0021] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] Example 1: like Figures 1-3 As shown, one embodiment of this utility model provides a safety mechanism, including an elastic element 1, a base 2, a limiting element 5, and two clamping structures 3; One side of the base 2 is provided with an elastic element 1, and the other side is symmetrically rotatably connected with a clamping structure 3; The elastic member 1 has two abutting parts 13, which are located between two clamping structures 3. The abutting parts 13 correspond one-to-one with the clamping structures 3 and are in contact with the clamping structures 3. A limiting area for limiting the safety bar 6 is formed between the limiting member 5 and the two clamping structures 3.

[0023] When the massage head extends or retracts normally, the safety lever 6 remains stationary within the limit zone. When the massage head is subjected to a large external force impact, the safety lever 6 moves along the second direction, squeezing the two clamping structures 3 apart. At this time, the two clamping structures 3 rotate, and one end of the two clamping structures 3 and the abutment part 13 approach each other, transmitting the force to the elastic element 1. The elastic element 1 undergoes elastic deformation, and the safety lever 6 exits the limit zone. The push-out mechanism assembly 9 can then collapse as a whole, buffering the impact from the external force.

[0024] Because the elastic element 1 is located on one side of the limiting area, rather than above the limiting area, the longitudinal space in that area can be reduced, thereby reducing the longitudinal space required by the massage chair in that area. The overall thickness of the seat is thinner, making it suitable for more car models and improving its practicality.

[0025] According to one embodiment of the present invention, the elastic element 1 includes a torsion spring 11 and a connecting post 12; The connecting post 12 is fixedly connected to the base 2, and the torsion spring 11 is sleeved on the connecting post 12. The torsion spring 11 has two abutment parts 13.

[0026] The two abutting parts 13 of the torsion spring 11 only need to contact or abut with the clamping structure 3, and do not need to be connected to the clamping structure 3, making the structure simpler.

[0027] According to one embodiment of the present invention, the clamping structure 3 includes an abutment plate 31 and a limiting plate 32 connected to each other; The abutting plate 31 and the abutting part 13 correspond one-to-one, and the abutting plate 31 and the abutting part 13 abut against each other; The limiting plate 32 has a limiting protrusion 321 on the side away from the abutment plate 31. The two limiting protrusions 321 cooperate to limit the movement of the bumper 6 in the second direction.

[0028] The side of the two limiting protrusions 321 that is close to each other is the first mating surface, and the distance between the two first mating surfaces is less than the distance between the side surfaces of the two limiting plates 32 that are close to each other. The side of the two limiting protrusions 321 closest to the torsion spring 11 is the second mating surface. The second mating surface cooperates with the vertical plate 52 to limit the movement of the bumper 6 along the length direction of the bumper 6.

[0029] The axis of the torsion spring 11 coincides with the axis of the connecting post 12. Preferably, the torsion spring 11 is positioned on the connecting post 12.

[0030] According to one embodiment of the present invention, the limiting plate 32 is rotatably connected to the base 2 via the rotating member 4.

[0031] According to one embodiment of the present invention, the rotating component 4 includes a first washer 41 and a second washer 42. The first washer 41 is provided between the top plate 51 and the limiting plate 32, and the second washer 42 is provided between the limiting plate 32 and the base 2.

[0032] By using the first shim 41 and the second shim 42, the top plate 51 and the base 2 do not come into contact with the limiting plate 32, making their rotation smoother.

[0033] According to one embodiment of the present invention, the two ends of the limiting member 5 are respectively connected to the base 2 via a rotating member 4; The limiting member 5 is used to restrict the movement of the bumper 6 in a first direction, which is opposite to the second direction.

[0034] According to one embodiment of the present invention, the limiting member 5 includes a top plate 51 and a vertical plate 52 connected together. The top plate 51 and the base 2 cooperate to limit the movement of the safety bar 6 along a third direction, which is perpendicular to the second direction. The base 2 has a through hole 21, one end of the vertical plate 52 is inserted into the through hole 21 and the side wall of the vertical plate 52 is in contact with the side wall of the through hole 21.

[0035] The push-out mechanism assembly 9 drives the safety rod 6 to move in the first direction. Since the safety rod 6 is blocked by the vertical plate 52, the push-out mechanism assembly 9 is subjected to a reaction force and moves in the second direction, thereby driving the massage head to retract and reset. During this process, the vertical plate 52 will be subjected to a pushing force. In order to improve the supporting force of the vertical plate 52, a through hole 21 is opened on the base 2 so that the lower end of the vertical plate 52 can be inserted into the through hole 21 and abut against the side wall of the through hole 21, so that the base 2 can support the vertical plate 52.

[0036] When the massage head is in its initial state, the side wall of the safety rod 6 is in contact with the side wall of the limiting plate 32.

[0037] The top plate 51 has second shaft holes at both ends, and the limiting plate 32 has first shaft holes. The rotating part 4 is rotatably connected to the first shaft hole.

[0038] The rotating member 4 comprises a pin 44 and a pin shaft 43, the pin shaft 43 is T-shaped, the shaft body of the pin shaft 43 sequentially passes through a first circular hole opened on the base 2, a second gasket 42, a first shaft hole and a first gasket 41, a top plate 51 is arranged above the pin shaft 43, the pin 44 passes through a second shaft hole and is screwed into an inner hole in the pin shaft 43, thereby limiting the clamping structure 3 and the limiting member 5 on the base 2 at the same time, the fixing mode is simple and convenient for disassembly and assembly. Preferably, the length of the shaft body of the pin shaft 43 is equal to the total thickness of the first gasket 41, the second gasket 42, the limiting plate 32 and the second plate body of the base 2.

[0039] According to an embodiment of the present utility model, the base 2 comprises a connected first plate body and a second plate body, and the second plate body is in an n-shaped shape.

[0040] The second plate body is designed into an n-shaped shape, the second plate body comprises a first flat plate, a second flat plate and a third flat plate connected in sequence, both the first flat plate and the third flat plate are in arc transition with the second flat plate, two second circular holes opened on the base 2 are respectively opened on the first flat plate and the third flat plate, a gap is left between the first flat plate and the bottom of the movable seat 7 to accommodate the head of the pin shaft 43, and the second flat plate is in contact with the movable seat 7. The n-shaped second plate body not only provides an accommodating space for the head of the pin shaft 43, but also enhances the strength of the base 2.

[0041] Preferably, the first plate body and the second plate body are integrally formed.

[0042] Embodiment 2: A massage movement comprises a safety mechanism, and further comprises an ejection mechanism assembly 9, a knocking mechanism assembly 10, a safety rod 6, a movable seat 7 and a base frame 8; The output end of the ejection mechanism assembly 9 is provided with the safety rod 6; The fixed end of the ejection mechanism assembly 9 and the fixed end of the knocking mechanism assembly 10 are both connected to the movable seat 7; The movable seat 7 is slidably connected to the base frame 8; The base 2 is connected to the base frame 8, specifically, the base 2 further comprises supporting ring columns 22, two first circular holes are opened on a side of the first plate body in the base 2 close to a torsion spring 11, the supporting ring columns 22 correspond to the first circular holes one by one, the base 2 is in threaded connection with the base frame 8 after bolts pass through the first circular holes and the supporting ring columns 22, thereby fixing the base 2 on the base frame 8.

[0043] The output end of the ejector assembly 9 is connected to the safety rod 6. When the ejector assembly 9 is working normally, the ejector assembly 9 drives the safety rod 6 to move (at this time, the distance between the safety rod 6 and the housing of the ejector assembly 9 decreases). Since the driving force of the ejector assembly 9 is less than the elastic force of the torsion spring 11, the safety rod 6 is limited by the limiting area and cannot move. Therefore, the ejector assembly 9 moves in the first direction, driving the striking mechanism assembly 10 and the movable seat 7 to move together in the first direction. At this time, the massage head extends and performs normal massage. After the massage is completed, the ejector assembly 9 drives the safety rod 6 to move (at this time, the distance between the safety rod 6 and the housing of the ejector assembly 9 increases). At this time, since the vertical plate 52 abuts against the safety rod 6, the safety rod 6 is still limited by the limiting area and cannot move. Therefore, the ejector assembly 9 moves relative to the safety rod 6, driving the striking mechanism assembly 10 and the movable seat 7 to move together in the second direction, and the massage head resets and retracts. When subjected to impact, the massage head is subjected to force, which is transmitted to the safety rod 6. The safety rod 6 moves in the second direction. The impact force overcomes the force of the torsion spring 11, forcing the two clamping structures 3 to rotate around the rotating member 4. The two abutting parts 13 of the torsion spring 11 move closer to each other, and the distance between the two limiting protrusions 321 increases, eventually causing the safety rod 6 to exit the limiting area. At this time, the safety rod 6, the push-out mechanism assembly 9, the striking mechanism assembly 10, and the movable seat 7 move as a whole in the second direction to achieve the overall collapse of the push-out mechanism assembly 9 and the striking mechanism assembly 10.

[0044] The striking mechanism assembly 10 has a drive shaft 101, and there is a gap of at least 10mm between the abutment plate 31 and the drive shaft 101, which does not affect the movement of the drive shaft 101 (the movement range of the drive shaft 101 is about 8mm). Similarly, the limiting member 5 does not affect the normal movement of the drive shaft 101.

[0045] It should be noted that the massage mechanism also includes a kneading and walking mechanism. The gap between the kneading and walking mechanism and the drive shaft 101 is used to install the torsion spring 11. After the safety mechanism is installed in place, other parts on the massage mechanism will not affect the normal movement of the safety mechanism.

[0046] like Figure 3 As shown, the safety bar 6 includes a threaded rod and a limiting rod head connected together. The cross-sectional area of ​​the end face of the limiting rod head away from the threaded rod is smaller than the cross-sectional area of ​​its other end face, which makes it easier for the safety bar 6 to be re-pressed into the limiting area.

[0047] Example 3: A chair may include the massage mechanism of Embodiment 1, or the insurance mechanism of Embodiment 2.

They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0049] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the connection within two components.
