Description

Technical Field

[0001] The invention relates to the technical field of automobile seats, and in particular to a safety collapse mechanism of an execution component of a massager. Background Art

[0002] For passengers who drive or ride for a long time, it is easy to cause body fatigue and muscle stiffness due to maintaining the same posture for a long time. In order to solve the fatigue problem derived from long-term driving and riding, a car seat with massage function came into being.

[0003] At present, most of the massage mechanisms for the waist and back area on car seats use air bag massage, but the air bag massage has low strength and poor massage effect, and it is difficult to fully and deeply relax the user's body. In order to overcome the above defects, the applicant intends to develop a mechanical massage device, which is prepared to use mechanical movement to massage the occupant's back to achieve a better massage effect. However, when the mechanical massage device is working, it usually requires a massage component protruding outward to directly press against the occupant's back or waist. If the vehicle collides or other emergencies occur, the protruding massage component will cause great harm to the occupant's body, posing certain safety hazards.

[0004] Therefore, how to improve the safety of mechanical massage devices is a technical problem that needs to be solved urgently. Summary of the invention

[0005] In view of this, the present invention provides a massager actuator safety collapse mechanism, when a vehicle collides, the massage actuator can be quickly retracted from the ejected state, thereby improving the safety of massage.

[0006] To achieve the above purpose, the technical solution of the present invention is as follows:

[0007] A massager actuator safety collapse mechanism, the key of which is that it comprises a base, a swing arm is rotatably mounted on the base, a massage component is arranged at the far end of the swing arm, a support component that can slide relative to the base is arranged below the swing arm, a connecting rod is hinged on the support component, and the other end of the connecting rod is hinged at the middle of the swing arm. The support component slides and can drive the swing arm to rotate via the connecting rod, so that the massage component moves away from or close to the base;

[0008] A thrust mechanism is provided on one side of the support component, and the thrust mechanism includes a limit block abutting against the support component and a driving component driving the limit block to move along the sliding direction of the support component. An elastic component is provided between the base and the support component, and the elastic component applies a force to make the support component abut against the limit block; when the massage component is pressed by external force, the support component can overcome the resistance of the elastic component and slide to make the massage component move toward the base.

[0009] With the above structure, when the massage component is not in use, the massage component and the swing arm are stored in the backrest. When the user needs to use the massage component for massage, the drive assembly drives the limit block to move away from the support component. During this process, since the elastic component exerts a force that causes the support component to continuously abut against the limit block, the support component can move synchronously with the limit block, so that under the linkage action of the connecting rod, the swing arm can be driven to rotate outward, so that the massage component at the far end of the swing arm can be pushed out to the front side of the backrest A and act on the waist and back of the occupant. After the massage is finished, the drive assembly drives the limit block to move in the direction close to the support component. At this time, the limit block pushes the support component to overcome the resistance of the elastic component to slide, so that under the linkage action of the connecting rod, the swing arm can be driven to rotate inward, so that the massage component is retracted toward the base.

[0010] Preferably, the elastic component is a compression spring, which abuts between the support component and the end of the base. The limit block moves in a direction close to the compression spring, which can force the compression spring to store force through the support component. The limit block moves in a direction away from the support component, which can release the elastic potential energy of the compression spring. The thrust generated by the compression spring can make the support component move synchronously with the limit block.

[0011] Preferably, a slide bar extending in the height direction is fixed on the base, the elastic component, the support component and the limit block are sequentially mounted on the slide bar in the height direction, and the support component and the limit block can slide up and down relative to the slide bar.

[0012] Preferably, the slide bar is fixedly mounted on the base via a mounting seat, one end of the elastic component is supported on the mounting seat, and the other end is in contact with the supporting component.

[0013] Preferably, the driving assembly comprises a motor fixed on the base and a screw driven to rotate by the motor, and one end of the limit block is threadedly mounted on the screw.

[0014] Preferably, two groups of the swing arms and connecting rods are provided, the two groups of the swing arms are symmetrically arranged along the width direction of the base, the number of the sliding rods is two groups, both ends of the supporting component and both ends of the limit block are respectively slidably connected to the two groups of sliding rods, and the screw rod is located between the two groups of sliding rods.

[0015] Preferably, the support component has a downwardly recessed avoidance groove in the middle, and the avoidance groove is used to accommodate the screw rod.

[0016] Preferably, a roller which is in sliding contact with the base is provided on the lower side of the support component.

[0017] Preferably, a synchronization shaft is rotatably connected to the support component, the synchronization shaft is arranged along the width direction of the base, both ends of the synchronization shaft are provided with adapters, and one end of the two groups of connecting rods are respectively hinged on the two adapters.

[0018] Preferably, the two groups of swing arms are rotatably mounted on the base via a rotating shaft at one end away from the massage component.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. The massager actuator safety collapse mechanism provided by the present invention is adopted, and the driving assembly drives the limit block to move away from the support component. In this process, since the elastic component exerts a force that causes the support component to continuously abut against the limit block, the support component can move synchronously with the limit block, so that the swing arm can be driven to rotate outward under the linkage action of the connecting rod, so that the massage component at the far end of the swing arm can be pushed out to the front side of the backrest and act on the waist and back of the occupant. The driving assembly drives the limit block to move in the direction close to the support component. At this time, the limit block pushes the support component to overcome the resistance of the elastic component to slide, so that the swing arm can be driven to rotate inward under the linkage action of the connecting rod, so that the massage component can be retracted toward the base. In the working state of the massage component, when the vehicle collides or other emergencies occur, and the massage component is compressed by external force, the support component can overcome the resistance of the elastic component to slide, so that the massage component can be quickly retracted toward the base, effectively avoiding the massager from causing harm to the human body, and having the advantage of good safety. When the external force disappears, the elastic component is reset, which can drive the swing arm and the massage component to return to their positions automatically.

[0021] 2. The safe collapse mechanism of the massager actuator provided by the present invention not only realizes that the massage component is stored inside the backrest when not in operation, avoiding that it protrudes from the backrest and causes discomfort to the user's waist, thus ensuring normal riding comfort, but also can smoothly unfold the massage component to a protruding state from the backrest through the synergistic effect of the elastic component and the thrust mechanism when massage is needed, thus realizing the massage function. In addition, in the event of a collision, the massage component can also be collapsed reversibly, thus improving the safety of massage. After collapse, the massage component is not damaged, thus saving costs and eliminating the trouble of replacing components. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The present invention is further described below in conjunction with embodiments and drawings.

[0035] like Figure 1 , 2As shown in Figure 6, a massager actuator safety collapse mechanism includes a base 1, a swing arm 2 is rotatably mounted on the base 1, a massage component 2a is provided at the far end of the swing arm 2, and a support component 3 that can slide relative to the base 1 is provided below the swing arm 2. A connecting rod 4 is provided between the support component 3 and the swing arm 2, one end of the connecting rod 4 is hinged on the support component 3, and the other end is hinged at the middle of the swing arm 2. The support component 3 slides and can drive the swing arm 2 to rotate through the connecting rod 4, so that the massage component 2a moves away from or close to the base 1. A thrust mechanism 5 is provided on one side of the support component 3, and the thrust mechanism 5 includes a limit block 5a and a driving assembly 5b, wherein the limit block 5a abuts against the support component 3, and the driving assembly 5b is used to drive the limit block 5a to move along the sliding direction of the support component 3. An elastic component 6 is provided between the base 1 and the support component 3, and the elastic component 6 applies a force that causes the support component 3 to continuously abut against the limit block 5a. When the massage component 2 a is pressed by an external force, under the coordinated transmission action of the swing arm 2 and the connecting rod 4 , the support component 3 can overcome the resistance of the elastic component 6 and slide, so that the massage component 2 a moves toward the base 1 .

[0036] refer to Fig.11 When the massager actuator safety collapse mechanism is applied to a car seat, the base 1 is a plate-like structure, which is installed in the backrest A of the seat, or is directly a part of the backrest frame. In this embodiment, the orientation of the mechanism is described with reference to the car seat, that is, the height direction of the base 1 corresponds to the height direction of the car seat, and the width direction of the base 1 corresponds to the width direction of the car seat.

[0037] Based on the above structural design, after the massager actuator safety collapse mechanism is integrated into the seat back, Figure 3 and 5 As shown, when the massage component 2a is not in use, the massage component 2a and the swing arm 2 are stored in the backrest, that is, the massage component 2a is closer to the base 1. When the user needs to use the massage component 2a for massage, please refer to the attached Figure 4 and 6 As shown, the driving assembly 5b drives the limit block 5a to move away from the support component 3. In this process, since the elastic component 6 exerts a force to make the support component 3 continuously abut against the limit block 5a, the support component 3 can move synchronously with the limit block 5a, so that under the linkage action of the connecting rod 4, the swing arm 2 can be driven to rotate outward, so that the massage component 2a at the far end of the swing arm 2 can be pushed out to the front side of the backrest A (refer to Fig.11), and acts on the waist and back of the occupant. After the massage is finished, the driving component 5b drives the limit block 5a to move in the direction close to the support component 3. At this time, the limit block 5a pushes the support component 3 to overcome the resistance of the elastic component 6 to slide, so that under the linkage action of the connecting rod 4, the swing arm 2 can be driven to rotate inward, so that the massage component 2a is retracted toward the base 1. Therefore, through such a structural design, not only the massage component 2a is stored inside the backrest in the non-working state, avoiding its protrusion from the backrest to cause diaphragm to the user's waist, ensuring normal riding comfort, but also when massage is needed, through the coordinated action of the elastic component 6 and the thrust mechanism 5, the massage component 2a can be smoothly unfolded to a protrusion from the backrest to achieve the massage function.

[0038] In addition, based on such an assembly method, the massage component 2a also has a passive collapse function in the working state. The specific process is as follows: when the massage component 2a is in the working state, when the vehicle collides or other emergencies occur, and the massage component 2a is pressed by external force, the support component 3 can overcome the resistance of the elastic component 6 and slide. Under the linkage action of the connecting rod 4, the massage component 2a can be driven to quickly retract toward the base 1, effectively avoiding the massager from causing harm to the human body and improving the safety of the massage. When the external force disappears, the elastic component 6 is reset, which can push the support component 3 to slide, and then drive the swing arm 2 and the massage component 2a to automatically return to the working state. Such a design can protect the massage component 2a from damage, save costs and eliminate the trouble of replacing parts, and has the advantage of good practicality.

[0039] Furthermore, the elastic component 6 may be a compression spring, a tension spring, a torsion spring, a leaf spring, a spring sheet, etc. In this embodiment, the elastic component 6 is a compression spring. Figure 6 The compression spring abuts between the support component 3 and the lower end of the base 1, and the limit block 5a moves downward along the height direction of the base 1, that is, moves in the direction close to the compression spring, which can push the support component 3 downward to compress the compression spring, so as to force the compression spring to store force, and the support component 3 moves downward, which can drive the swing arm 2 to rotate toward the base 1 through the connecting rod 4 (refer to Figure 5 ). When the limit block 5a moves in the direction away from the support component 3, that is, moves upward, the elastic potential energy of the compression spring can be released, and the thrust generated by the compression spring can make the support component 3 move synchronously with the limit block 5a, thereby driving the swing arm 2 to rotate outward through the connecting rod 4. In this state, when the massage component 2a is pressed by external force, the support component 3 can press the compression spring downward, and then drive the swing arm 2 to quickly retract toward the base 1 through the connecting rod 4; when the external force disappears, the compression spring can release energy and push the support component 3 to move upward until the support component 3 abuts against the limit block 5a. At this time, the swing arm 2 returns to the working position and the massage component 2a is not damaged by external force.

[0040] Re-attend Figure 4The base 1 is fixed with a slide bar 7 extending in the height direction thereof, and the elastic component 6, the support component 3 and the limit block 5a are sequentially mounted on the slide bar 7 from bottom to top, and the support component 3 and the limit block 5a can slide up and down relative to the slide bar 7. Such a design ensures the reliability of the installation and movement of the elastic component 6, the support component 3 and the limit block 5a.

[0041] Depend on Figure 7 It can be seen that the slide bar 7 is fixedly assembled on the base 1 through the mounting seat 8, one end of the elastic component 6 is supported on the mounting seat 8, and the other end is in contact with the supporting component 3. This consideration is for easy installation.

[0042] like Figure 7 As shown, the driving assembly 5b includes a motor 51 fixed on the base 1 and a screw rod 52 driven to rotate by the motor 51, the screw rod 52 extends along the height direction of the base 1, and one end of the limit block 5a is threadedly mounted on the screw rod 52. The motor 51 drives the screw rod 52 to rotate, which can drive the limit block 5a to move up and down along the screw rod 52.

[0043] Furthermore, Figure 1 and 3 As shown, in order to massage the meridians on both sides of the spine at the same time, the massage component 2a is provided with two groups, and the swing arm 2 and connecting rod 4 matched therewith are also provided with two groups. The two groups of swing arms 2 are symmetrically arranged along the width direction of the base 1. In this embodiment, the two groups of swing arms 2 are rotatably mounted on the base 1 through the rotating shaft 9 at one end away from the massage component 2a. The number of the slide rod 7 and the elastic component 6 are both two groups, and they correspond to the two groups of swing arms 2 one by one. Both ends of the support component 3 and both ends of the limit block 5a are respectively slidably sleeved with the two groups of slide rods 7, and the two connecting rods 4 are symmetrically arranged on the sides of the two groups of swing arms 2, and the screw rod 52 is arranged between the two groups of slide rods 7. The motor 51 drives the limit block 5a to move downward, which can drive the support component 3 to squeeze the two groups of elastic components 6 at the same time, and then can drive the two groups of swing arms 2 to retract inward at the same time, ensuring the synchronization of the movement of the two groups of swing arms 2. At the same time, such a layout method can improve the compactness of the overall structure, so that the mechanism can be better integrated and installed on the backrest of the car seat.

[0044] Combination Figure 7 and Fig.10 As shown, both ends of the limit block 5a have first connection holes 5a1, and the two first connection holes 5a1 are respectively slidably sleeved on the two sets of slide rods 7. The middle part of the limit block 5a is provided with a second connection hole 5a2, and the second connection hole 5a2 is threadedly sleeved on the screw rod 52.

[0045] Please refer to Figure 8 and 9The two ends of the support component 3 are provided with sleeve joints 3c respectively slidably mounted on the two sets of slide rods 7, and one end of the compression spring abuts against the corresponding sleeve joint 3c. The middle part of the support component 3 has a downwardly concave avoidance groove 3b, and the screw rod 52 is located above the avoidance groove 3b, which further improves the compactness of the structure.

[0046] Re-attend Figure 8 A roller 3a is provided on the lower side of the support component 3 in sliding contact with the base 1. The roller 3a increases the smoothness of the support component 3 sliding on the base 1. On the other hand, when a collision occurs, the support component 3 can also smoothly squeeze the compression spring downward to ensure that the swing arm 2 can be quickly retracted.

[0047] like Figure 2 and Figure 4 As shown, the support component 3 is rotatably connected with a synchronization shaft 3c, which is arranged along the width direction of the base 1. Both ends of the synchronization shaft 3c are provided with a transfer portion 3d, and one end of the two sets of connecting rods 4 is respectively hinged on the two transfer portions 3d, and the other end is respectively hinged on the middle of the corresponding swing arm 2. Such a design is convenient for installation.

[0048] In practical applications, the massage component 2a can be an independent massage device or a massage actuator driven by the swing arm 2. Figure 1 , 11 12, taking the massage component 2a as a massage actuator as an example, two groups of annular grooves 91 are symmetrically arranged on the upper edge of the rotating shaft 9, and the ends of the two swing arms 2 away from the massage component 2a are respectively rotated and sleeved on the two annular grooves 91, and the side walls of each annular groove 91 are inclined relative to the center line of the rotating shaft 9. The base 1 is also provided with a driving mechanism for driving the rotating shaft 9 to rotate. When using the massage function, the driving component 5b drives the limit block 5a to move away from the support component 3, and the support component 3 can move synchronously with the limit block 5a, so that under the linkage action of the connecting rod 4, the two groups of swing arms 2 can be driven to rotate outward, so that the massage component 2a at the far end of the swing arm 2 can be pushed out to the front side of the backrest A and act on the user's back. Afterwards, the driving mechanism drives the rotating shaft 9 to rotate, and under the transmission of the inclined side wall of the annular groove 91 and the restraining action of the connecting rod 4, the swing arm 2 is forced to swing back and forth along the axial direction of the rotating shaft 9, so that the massage component 2a at the far end forms a reciprocating swing kneading massage on the user's back.

[0049] Finally, it should be noted that the above description is only a preferred embodiment of the present invention. Under the guidance of the present invention, ordinary technicians in this field can make various similar expressions without violating the purpose and claims of the present invention, and such changes all fall within the scope of protection of the present invention.
