Description

Technical Field

[0001] This invention relates to the field of massage equipment technology, and in particular to a collapsible structure for a massage mechanism. Background Technology

[0002] With the rapid development of the automotive industry and the increasing demands of consumers for ride comfort, in-vehicle seat massage systems have become an important feature in mid-to-high-end models to enhance the driving and riding experience. These systems typically integrate a mechatronic massage mechanism within the seat, where the massage arms, driven by a mechanism, perform kneading, tapping, and other actions to effectively relieve passenger fatigue.

[0003] However, during actual vehicle operation, especially in the event of a collision or emergency braking, the occupant's body will experience violent displacement relative to the seat due to inertia. If the extended massage arm maintains rigid support at this time, it may cause secondary injuries such as impact or compression to the occupant's back, which contradicts the design principles of automotive passive safety. Therefore, introducing a reliable and timely crumple zone protection mechanism for the massage mechanism has become a pressing safety issue that needs to be addressed in this field. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings and deficiencies of the existing technology and to provide a collapsible structure for a massage mechanism.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a collapsible structure for a massage mechanism, comprising a guide rod, a movable seat, a sliding sleeve, and a connecting rod; the guide rod is connected to a frame; the movable seat is connected to the guide rod; the sliding sleeve is slidably fitted onto the guide rod; one end of the connecting rod is hinged to the sliding sleeve, and the other end is hinged to the massage arm of the massage mechanism; the movable seat is provided with an elastic storage clip, the elastic storage clip having an elastic latch; the sliding sleeve includes a release rod extending toward the elastic storage clip, the end of the release rod having a release boss; the release boss can open the elastic latch and enter the storage space of the elastic storage clip, so that the sliding sleeve and the movable seat remain relatively locked; when the downward impact force borne by the massage arm is transmitted to the connecting rod and exceeds the clamping force of the elastic latch, the connecting rod drives the sliding sleeve to slide along the guide rod, causing the release boss to disengage from the elastic latch, thereby realizing the collapse of the massage arm.

[0006] By adopting the above technical solution, a mechanical locking mechanism is achieved by using an elastic storage clip with a flexible latch that engages with a release boss on the sliding sleeve. The collapse trigger threshold is determined by the clamping force of the elastic latch, ensuring stability and reliability. In the event of a collision, the impact force is directly transmitted to the sliding sleeve through the connecting rod. This short force path and rapid response allow for timely collapse of the massage arm, absorbing impact energy and enhancing the passive safety of the seat massage system.

[0007] As a preferred embodiment of the present invention, the elastic storage clip includes a U-shaped storage frame and two elastic clamps; the two elastic clamps are respectively connected to the outer ends of two opposite baffles of the U-shaped storage frame, and an elastic slot is formed between the two elastic clamps for the release boss to enter or disengage.

[0008] By adopting the above technical solution, the elastic storage clip uses a U-shaped storage frame and two independent elastic clamping plates, which is simple in construction. The two elastic clamping plates are respectively connected to both sides of the U-shaped frame to form a symmetrical elastic clamping force, ensuring that the release boss is subjected to uniform radial constraint, thereby improving the stability of the locking state and the consistency of the collapse action.

[0009] As a preferred embodiment of the present invention, each elastic clamp includes a limiting section connected to the baffle and a guide section connected to the outer end of the limiting section. The limiting section and the guide section form a V-shaped structure, and the guide sections of the two elastic clamps extend at opposite angles. The limiting section is used to restrict the release boss from disengaging from the storage space. The release boss is frustum-shaped. When the release boss enters the elastic latch, its conical surface cooperates with the guide section and opens the two elastic clamps. When the downward impact force borne by the massage arm drives the release boss to disengage, the release boss cooperates with the limiting section and opens the two elastic clamps.

[0010] By adopting the above technical solution, the elastic clamp adopts a V-shaped segmented design, including a limiting section and a guide section. The guide section extends at opposite angles to form a trumpet-shaped guide structure, which facilitates the smooth sliding of the release boss into the elastic latch during reset. The limiting section is used to prevent the release boss from disengaging in the locked state. The structure is clear and the functions are separated, which not only ensures reliable locking during normal use, but also ensures that under excessive impact, the release boss can achieve controllable opening and release through the abutment of the limiting section, resulting in high reliability.

[0011] As a preferred embodiment of the present invention, the U-shaped storage frame includes a side plate for connecting two baffles; the movable seat has a slot for inserting the side plate, and the movable seat is also threaded with a fastening screw for fixing the side plate in the slot so that the elastic storage clip remains fixed relative to the movable seat.

[0012] By adopting the above technical solution, the U-shaped storage frame is inserted into the slot on the movable base through the side plate and fixed with fastening screws, realizing the detachable installation of the flexible storage clip. This structure facilitates assembly, debugging, and subsequent maintenance.

[0013] As a preferred embodiment of the present invention, the sliding sleeve includes a sleeve and support plates extending upward from both sides of the sleeve; a connecting pin is provided between the two support plates; one end of the connecting rod is provided with an elongated hole or sliding groove that mates with the connecting pin to achieve a sliding hinge connection between the connecting rod and the sliding sleeve; the other end of the connecting rod is provided with a ball head and forms a ball hinge connection with a ball socket provided on the massage arm.

[0014] By adopting the above technical solution, the sliding sleeve and the connecting rod are connected by a sliding hinge consisting of a connecting pin and an elongated hole (or a sliding groove), while the connecting rod and the massage arm are connected by a ball joint, forming a composite connection form of "sliding hinge-ball joint". This design not only ensures the freedom of movement of the massage arm when performing complex actions such as kneading and scraping, avoiding mechanical interference, but also effectively transmits force to the sliding sleeve when subjected to downward impact, ensuring that the collapse trigger and the massage function do not interfere with each other, thus improving the overall coordination and reliability of the system.

[0015] As a preferred embodiment of the present invention, at least a portion of the guide rod is provided with external threads; the movable seat and the externally threaded portion constitute a threaded transmission pair, enabling the movable seat to move relative to the frame along the axial direction of the guide rod.

[0016] By adopting the above technical solution, and by setting an external threaded section on the guide rod to form a threaded transmission pair with the movable seat, the movable seat can be precisely adjusted along the axial direction of the guide rod. This enables flexible adjustment of the working angle of the massage arm to adapt to the body shape preferences or seat contours of different occupants, improving massage fit and comfort. On the other hand, after a collapse action occurs, the movable seat can be driven to move towards the sliding sleeve by forward rotation, causing the elastic storage clip on it to re-"capture" and guide the release boss to slide into the elastic latch, thereby achieving convenient and reliable reset of the mechanism, enhancing the product's recoverability and overall service life.

[0019] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0020] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0021] like Figure 1-7 The illustrated collapsible structure for a massage mechanism includes a guide rod 1, a movable seat 2, a sliding sleeve 3, and a connecting rod 4. The guide rod 1 is connected to a frame 5. The movable seat 2 is connected to the guide rod 1. The sliding sleeve 3 is slidably fitted onto the guide rod 1. One end of the connecting rod 4 is hinged to the sliding sleeve 3, and the other end is hinged to the massage arm 23 of the massage mechanism. The movable seat 2 is provided with an elastic storage clip 6, which has an elastic latch 7. The sliding sleeve 3 includes a release rod extending toward the elastic storage clip 6. 8. The end of the release lever 8 is provided with a release boss 9; the release boss 9 can open the elastic latch 7 and enter the storage space 10 of the elastic storage clip 6 so that the sliding sleeve 3 and the movable seat 2 are locked relative to each other; when the downward impact force on the massage arm 23 is transmitted to the connecting rod 4 and exceeds the clamping force of the elastic latch 7, the connecting rod 4 drives the sliding sleeve 3 to slide along the guide rod 1, so that the release boss 9 is disengaged from the elastic latch 7, thereby realizing the collapse of the massage arm 23.

[0022] By setting an elastic storage clip 6 with a flexible latch 7 to cooperate with the release boss 9 on the sliding sleeve 3, locking is achieved by mechanical latching. The collapse trigger threshold is determined by the clamping force of the elastic latch 7, which is stable and reliable. In the event of a collision, the impact force is directly transmitted to the sliding sleeve 3 through the connecting rod 4. The force flow path is short and the response is rapid, which can realize the timely collapse of the massage arm 23, absorb the impact energy, and improve the passive safety of the seat massage system.

[0023] The improvements in this application mainly lie in the mechanical structure and kinematic coordination of the collapsible structure used in the massage mechanism, including the connection methods, interactions, and triggering and resetting mechanisms among mechanical components such as the guide rod 1, movable seat 2, sliding sleeve 3, connecting rod 4, elastic storage clip 6, and release boss 9. In particular, it involves a purely mechanical collapsible scheme that achieves stable threshold triggering and reliable resetting through the cooperation of the elastic latch 7 and the release boss 9. This application does not involve improvements to circuit design, control methods, signal processing, or software programs; the relevant electrical and control parts are implemented using conventional techniques known in the art.

[0024] The elastic storage clip 6 includes a U-shaped storage frame 11 and two elastic clips 12; the two elastic clips 12 are respectively connected to the outer ends of two opposing baffles 16 of the U-shaped storage frame 11, and an elastic latch 7 is formed between the two elastic clips 12 for the release protrusion 9 to enter or disengage.

[0025] The elastic storage clip 6 adopts a U-shaped storage frame 11 and two independent elastic clamping plates 12, which is simple in construction. The two elastic clamping plates 12 are respectively connected to both sides of the U-shaped frame to form a symmetrical elastic clamping force, ensuring that the release boss 9 is subjected to uniform radial constraint, thereby improving the stability of the locking state and the consistency of the collapse action.

[0026] Each of the elastic clamps 12 includes a limiting section 13 connected to the baffle 16 and a guide section 14 connected to the outer end of the limiting section 13. The limiting section 13 and the guide section 14 form a V-shaped structure, and the guide sections 14 of the two elastic clamps 12 extend in opposite directions. The limiting section 13 is used to restrict the release boss 9 from disengaging from the storage space 10. The release boss 9 is frustum-shaped. When the release boss 9 enters the elastic latch 7, its conical surface cooperates with the guide section 14 and opens the two elastic clamps 12. When the downward impact force on the massage arm 23 drives the release boss 9 to disengage, the release boss 9 cooperates with the limiting section 13 and opens the two elastic clamps 12.

[0027] The elastic clamp 12 adopts a V-shaped segmented design, including a limiting section 13 and a guide section 14. The guide section 14 extends obliquely in opposite directions to form a funnel-shaped guide structure, which facilitates the smooth sliding of the release boss 9 into the elastic latch 7 during reset. The limiting section 13 is used to prevent the release boss 9 from disengaging in the locked state. The structure is clear and the functions are separated, which not only ensures reliable locking during normal use, but also ensures that under excessive impact, the release boss 9 can be controlled to open and release through the contact between the release boss 9 and the limiting section 13, resulting in high reliability.

[0028] The U-shaped storage frame 11 includes side plates 15 for connecting two baffles 16; the movable base 2 has slots 17 for inserting the side plates 15, and the movable base 2 is also threaded with fastening screws 18 for fixing the side plates 15 into the slots 17, thus keeping the elastic storage clip 6 fixed relative to the movable base 2. The U-shaped storage frame 11 achieves detachable installation of the elastic storage clip 6 by inserting the side plates 15 into the slots 17 on the movable base 2 and fixing them with the fastening screws 18. This structure facilitates assembly, debugging, and subsequent maintenance.

[0029] The sliding sleeve 3 includes a sleeve 19 and support plates 20 extending upward from both sides of the sleeve 19; a connecting pin 21 is provided between the two support plates 20; one end of the connecting rod 4 is provided with an elongated hole or groove that mates with the connecting pin 21 to achieve a sliding hinge between it and the sliding sleeve 3; the other end of the connecting rod 4 is provided with a ball head 22, which forms a ball joint connection with a ball socket on the massage arm 23. The sliding sleeve 3 and the connecting rod 4 are connected by a sliding hinge formed by the connecting pin 21 and the elongated hole (or groove), and the connecting rod 4 and the massage arm 23 are connected by a ball joint, forming a composite connection form of "sliding hinge-ball joint". This design not only ensures the freedom of movement of the massage arm 23 when performing complex actions such as kneading and scraping, avoiding mechanical interference, but also effectively transmits force to the sliding sleeve 3 when subjected to downward impact, ensuring that the collapse trigger and the massage function do not interfere with each other, thus improving the overall coordination and reliability of the system.

[0030] In this embodiment, a preferred mode of operation of the collapsible structure of the in-vehicle massage mechanism according to this application will be described in detail. It should be understood that the following description is intended to clearly illustrate the principle and operation of the core structure of the invention, and not to constitute any limitation on the scope of protection of the invention. This collapsible structure is mainly applied to in-vehicle massage mechanisms. The massage arm 23 can be connected to a rotating kneading shaft through an eccentric transmission mechanism, thereby performing massage actions such as kneading and scraping under the action of a drive component (drive motor). This is prior art and therefore not specifically described. It should be noted that the specific driving form and movement trajectory of the massage arm 23 are not the focus of this invention. The main purpose and core innovation of this invention is to provide a reliable, automatically resetting mechanical collapsible protection mechanism for the massage arm 23.

[0031] At least a portion of the guide rod 1 is provided with external threads (not shown in the figure); the movable seat 2 and the externally threaded section form a threaded transmission pair, enabling the movable seat 2 to move axially relative to the frame 5 along the guide rod 1. In this application, the relative movement between the movable seat 2 and the housing can be achieved through various guiding and mating structures. For example, the movable seat 2 may be provided with a slider, and the housing may be provided with a corresponding sliding groove, with guidance achieved through the sliding fit between the slider and the sliding groove; or, the frame 5 may include two parallel guide rods 1, and the movable seat 2 is simultaneously fitted onto the two guide rods 1 and slides along their axial direction. These embodiments are all used to achieve smooth and directional movement of the movable seat 2 relative to the housing.

[0032] By setting an external threaded section on the guide rod 1 to form a threaded transmission pair with the movable seat 2, the movable seat 2 can be precisely adjusted along the axial direction of the guide rod 1. This enables flexible adjustment of the working angle of the massage arm 23 to adapt to the body shape preferences or seat contours of different occupants, improving massage fit and comfort. On the other hand, after a collapse action occurs, the movable seat 2 can be driven to move towards the sliding sleeve 3 by forward rotation, causing the elastic storage clip 6 on it to re-"capture" and guide the release boss 9 to slide into the elastic latch 7, thereby achieving convenient and reliable reset of the mechanism, enhancing the product's recoverability and overall service life.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as defined by the appended claims and their equivalents.
