Description

Technical Field

[0001] The present invention relates to the technical field of seat massage, and specifically to a shiatsu massage machine and an automobile seat equipped with a shiatsu massage machine.

Background Art

[0002] With the progress of science and technology, the requirements for the comfort of automobile seats are constantly increasing. For automobile driving, continuous long-term driving not only causes physical fatigue but also makes the muscles of the body tense due to maintaining the same posture for a long time, resulting in muscle pain, which is likely to have an adverse effect on health. Therefore, automobile seats with a massage function have already been commercially available to relieve the fatigue of passengers caused by long-term driving or riding.

[0003] However, many of the currently commercially available massage mechanisms for the waist and back regions adopt airbag-type massage. The strength of the airbag-type massage is relatively low, the massage effect is not good, and it is difficult to completely relax the muscles of the user's waist and back to the deep part, so the user cannot completely relax the body.

Summary of the Invention

[0007] By adopting the above structure, when the massage function is not in use, the acupressure head and rotating bracket are stored inside the backrest, preventing them from protruding from the backrest and causing discomfort to the user's lower back, thus ensuring a comfortable ride. When the massage function is used, the second drive mechanism drives the rotating bracket to rotate outward, allowing the acupressure head at the end of the rotating bracket to protrude to the front of the backrest and act on the rider's lower back and spine. The first drive mechanism drives the slide to move up and down, moving the two acupressure heads up and down along the meridians on both sides of the rider's spine, thereby mimicking a reciprocating acupressure massage technique.

[0008] Preferably, the second drive mechanism includes a support portion slidably mounted on a slide and a thrust assembly that controls the sliding of the support portion, and the rotating bracket and the support portion are connected via a connecting rod, one end of which is hinged to the rotating bracket and the other end of which is hinged to the support portion, so that the rotating bracket can be rotated via the connecting rod by the sliding of the support portion.

[0009] Preferably, the thrust assembly includes a limiter that abuts against the support and a drive member that drives the limiter and moves it in the sliding direction of the support, and an elastic element is provided between the slide and the support to apply a force that causes the support to abut against the limiter, so that when the acupressure head is subjected to an external force and compressed, the support can slide over the resistance of the elastic element and move the acupressure head in the direction of the slide.

[0010] Preferably, the elastic element is a compression spring that contacts the support portion and the slide end. When the limiter moves toward the compression spring, force can be stored in the compression spring via the support portion. When the limiter moves toward the support portion, the elastic potential energy of the compression spring can be released. The thrust generated by the compression spring can move the support portion simultaneously with the limiter.

The sliding rods, elastic elements, and connecting rods are each provided in two sets. The two sets of sliding rods are arranged symmetrically in the width direction of the slide, and the two sets of elastic elements are each mounted on two sliding rods.

[0017] Compared to conventional technology, the beneficial effects of the present invention are as follows:

[0018] 1. By adopting the acupressure massage machine provided in this invention and integrating it onto the backrest of a car seat, when the massage function is not in use, the acupressure head and rotating bracket are stored within the backrest, preventing them from protruding from the backrest and causing discomfort to the user's lower back, thus ensuring comfortable normal riding. When the massage function is used, the second drive mechanism drives the rotating bracket to rotate outward, allowing the acupressure head at the end of the rotating bracket to protrude to the front of the backrest and act on the passenger's lower back and back. The first drive mechanism drives the slide to move up and down, moving the two acupressure heads up and down along the meridians on both sides of the spine of the passenger's back, thereby mimicking the reciprocating acupressure massage technique and having the advantage of providing a good massage effect. Furthermore, by controlling the angle at which the rotating bracket rotates outward, the depth of the massage by the acupressure head can be adjusted, allowing users of various body types to obtain an effective massage.

[0019] 2. By adopting the acupressure massage machine provided in the present invention, the acupressure head further has the function of passively collapsing in the operating state. In the event of a sudden situation such as a collision occurring in the vehicle, when the acupressure head is compressed by an external force, the support part can overcome the resistance force of the elastic element and slide, quickly retracting the acupressure head in the sliding direction, effectively preventing the acupressure head from causing injury to the human body, thus having the advantage of good safety.

[0020] 3. By providing linear drive units and guide assemblies at both ends, smooth vertical movement of the slide can be achieved with fewer parts, and mounting space can be left in the center of the slide, making it convenient for attaching massage members. It has the advantages of a rational layout and compactness, which is advantageous for designing a thinner product. [Brief explanation of the drawing]

Embodiments for Carrying Out the Invention

[0022] Hereinafter, the present invention will be further described in combination with embodiments and drawings.

[0023] As shown in Figure 16, the car seat includes a backrest F on which a shiatsu massage machine is integrated and mounted, capable of massaging the meridians on both sides of the user's spine using a shiatsu massage technique. As shown in Figures 1-3, the shiatsu massage machine includes a mounting base A on which a slide B that slides in the height direction is provided, and a first drive mechanism C that drives the slide B to move up and down. In this embodiment, both the mounting base A and the slide B are plate-shaped structures. A rotating bracket is rotatably mounted on the slide B, and two sets of shiatsu heads B2 for acting on the meridians on both sides of the user's spine are provided at one end away from the rotation center of the rotating bracket. A second drive mechanism D is provided on the slide B, which drives and rotates the rotating bracket, allowing the shiatsu heads B2 to protrude outward or be housed inward relative to the mounting base A. In this embodiment, the shiatsu heads B2 are roller-type massage heads.

[0024] Based on this, when the massage function is not in use, the acupressure head B2 and the rotating bracket are stored inside the backrest, meaning the acupressure head B2 is closer to the position of slide B, preventing the acupressure head B2 from protruding from the backrest and causing discomfort to the user's waist, thus ensuring a comfortable ride. When the user needs to use the acupressure head B2 for massage, the second drive mechanism D drives the rotating bracket to rotate outward, allowing the acupressure head B2 at the end of the rotating bracket to protrude to the front of the backrest F (see Figure 16), acting on the rider's waist and back. Subsequently, the first drive mechanism C drives slide B to move up and down, moving the two sets of acupressure heads B2 up and down along the meridians on both sides of the rider's spine, thereby mimicking a reciprocating acupressure massage technique and having the advantage of providing a good massage effect. Furthermore, by controlling the angle at which the rotating bracket rotates outward, the depth of the massage by the acupressure head B2 can be adjusted, thereby ensuring that users of various body types can achieve complete relaxation.

[0025] For specific applications, the rotating bracket may be designed as an integrated rotating bracket or as two sets of independent acupressure head arms B1, as needed. In this embodiment, the rotating bracket includes two sets of acupressure head arms B1 arranged symmetrically in the width direction of the slide B, and two sets of acupressure heads B2 are provided at the ends of the two sets of acupressure head arms B1, with one end of each set of acupressure head arms B1 away from the acupressure heads B2 rotatably mounted on the slide B via a rotating shaft.

[0026] Furthermore, as shown in Figures 3 to 5, the second drive mechanism D includes a support portion D4 slidably mounted on the slide B and a thrust assembly that controls the sliding of the support portion D4. The acupressure head arm B1 and the support portion D4 are connected via a connecting rod D5, one end of which is hinged to the center of the acupressure head arm B1 and the other end of which is hinged to the support portion D4. The sliding of the support portion D4 allows the acupressure head arm B1 to rotate via the connecting rod D5. When the thrust assembly drives the support portion D4 to slide upward, the acupressure head arm B1 can be simultaneously rotated outward via the connecting rod D5. When the thrust assembly drives the support portion D4 to slide downward, the acupressure head arm B1 can be simultaneously rotated inward under the interlocking action of the connecting rod D5, allowing the acupressure head B2 to be housed in the direction of the slide B. Since the drive mechanism of both sets of Shiatsu Head Arm B1 is the same, we will explain in detail using one set of Shiatsu Head Arm B1 as an example.

[0027] As shown in Figures 6 and 7, the thrust assembly includes a limiter D2 that abuts against a support D4, and a drive member D3 that drives the limiter D2 to move in the sliding direction of the support D4. An elastic element D1 is provided between the slide B and the support D4, applying a force that causes the support D4 to abut against the limiter D2. When the acupressure head B2 is subjected to an external force and compressed, the support D4 overcomes the resistance of the elastic element D1 and slides, allowing the acupressure head B2 to move in the direction of the slide B. With this design, when the user needs to use the acupressure head B2 to perform a massage, the drive member D3 drives the limiter D2 to move away from the support D4. During this process, a force is applied to the elastic element D1 that keeps the support part D4 in contact with the limiter D2. As a result, the support part D4 can move simultaneously with the limiter D2, and under the interlocking action of the connecting rod D5, the acupressure head arm B1 is rotated outward, causing the acupressure head B2 at the end of the acupressure head arm B1 to protrude forward from the backrest A. After the massage is finished, the drive member D3 drives the limiter D2 to move it toward the support part D4. At this time, the limiter D2 pushes the support part D4, overcoming the resistance of the elastic element D1 and sliding, which under the interlocking action of the connecting rod D5 moves the acupressure head arm B1 inward, allowing the acupressure head B2 to be housed in the direction of slide B.

[0028] In addition, based on this mounting method, the acupressure head B2 also has the function of passively collapsing when in operation. The specific process is as follows: If a sudden situation such as a collision occurs to the vehicle while the acupressure head B2 is in operation, and the acupressure head B2 is compressed by an external force, the support part D4 can overcome the resistance of the elastic element D1 and slide, and under the interlocking action of the connecting rod D5, the acupressure head B2 is moved and quickly retracted in the direction of slide B, effectively preventing the acupressure head B2 from causing injury to the human body and enhancing the safety of the massage. When the external force disappears, the elastic element D1 returns to its original position, pushing and sliding the support part D4, thereby moving the acupressure head arm B1 and the acupressure head B2, and automatically returning them to the operating position. With this design, the acupressure head B2 is protected from damage, costs are saved, the hassle of replacing parts is eliminated, and it has the advantage of being highly practical.

[0029] Furthermore, the elastic element D1 may be a compression spring, tension spring, torsion spring, leaf spring, etc., and in this embodiment, the elastic element D1 is a compression spring. Also, as shown in Figures 6 and 7, the compression spring abuts between the support part D4 and the lower end of the slide B, and the limiter D2 moves downward in the height direction of the slide B, that is, moves in a direction closer to the compression spring, pushing the support part D4 and compressing the compression spring downward, allowing the compression spring to store force. When the support part D4 moves downward, it can move the acupressure head arm B1 via the connecting rod D5 and rotate it in the direction of the slide B. When the limiter D2 moves away from the support part D4, that is, moves upward, it can release the elastic potential energy of the compression spring, and the thrust generated by the compression spring can move the support part D4 along the limiter D2 simultaneously, thereby moving the acupressure head arm B1 via the connecting rod D5 and rotating it outward. In this state, when the acupressure head B2 is subjected to an external force and compressed, the support D4 pushes the compression spring downward, thereby moving the acupressure head arm B1 via the connecting rod D5 and quickly retracting it in the direction of slide B. When the external force disappears, the compression spring releases energy, pushing the support D4 and moving it upward until the support D4 contacts the limiter D2. At this point, the acupressure head arm B1 returns to its operating position, and the acupressure head B2 is not damaged by the external force.

[0030] As shown in Figures 6 and 7, a sliding rod D6 extending in the height direction is fixed to the slide B, and the elastic element D1, support part D4, and limiter D2 are sequentially installed on the sliding rod D6 from bottom to top, and the support part D4 and limiter D2 can slide up and down relative to the sliding rod D6. This design ensures the reliability of the mounting and movement of the elastic element D1, support part D4, and limiter D2.

[0031] Furthermore, as shown in Figures 5 and 9, there are two sets of sliding rods D6, which are arranged symmetrically in the width direction of slide B, with one set of sliding rods D6 corresponding to one set of acupressure head arms B1. There are also two sets of elastic elements D1 and connecting rods D5, each set of elastic elements D1 covering two sliding rods D6, both ends of the limiter D2 and both ends of the support part D4 are slidably connected to the two sliding rods D6, and the two connecting rods D5 are provided symmetrically on the sides of the two sets of acupressure head arms B1.

[0032] As shown in Figure 9, the drive member D3 includes a second motor D31 fixed to the slide B and a second threaded rod D32 driven and rotated by the second motor D31. The second threaded rod D32 extends in the height direction of the slide B and is located between two sets of sliding rods D6. The central part of the limiter D2 is covered on the second threaded rod D32 by threads. The second motor D31 drives the limiter D2 downward, moves the support D4, and can simultaneously press the two sets of elastic elements D1. This allows the two sets of acupressure head arms B1 to move inward simultaneously and ensure the synchronization of the movement of the two sets of acupressure head arms B1. Furthermore, this layout enhances the overall compactness of the structure, allowing the mechanism to be more efficiently integrated and mounted on the backrest of an automobile seat.

[0033] As can be seen in Figure 9, a mounting base D7 is fixed to the lower end of slide B, and the ends of the two sliding rods D6 are both fixedly connected to both ends of the mounting base D7 in the width direction, while the lower end of the second threaded rod D32 is rotatably supported in the center of the mounting base D7. On the same sliding rod D6, one end of the elastic element D1 is supported on the mounting base D7, and the other end abuts against the corresponding support part D4. This consideration ensures the reliability of the mounting.

[0034] As shown in Figures 9 and 12, both ends of the limiter D2 have first connection holes D21, and the two first connection holes D21 are slidably covered on two sets of sliding rods D6. A second connection hole D22 is provided in the center of the limiter D2, and the second connection hole D22 is covered by a screw thread on a second threaded rod D32.

[0035] As shown in Figures 10 and 11, covering parts D41 are provided at both ends of the support part D4, each slidably covering two sets of sliding rods D6, and one end of the compression spring abuts against the corresponding covering part D41. The support part D4 has a downward-facing recessed avoidance groove D42 in the center, and the second threaded rod D32 is located above the avoidance groove D42, further enhancing the compactness of the structure.

[0036] Furthermore, as shown in Figure 10, a first wheel D8 is provided on the lower side of the support part D4, which slidably contacts the slide B. This first wheel D8 increases the smoothness of the support part D4 sliding on the slide B, while also ensuring that in the event of a collision, the support part D4 can smoothly push the compression spring downward, allowing the acupressure head arm B1 to be quickly retracted.

[0037] As shown in Figure 13, the first drive mechanism C includes a linear drive unit C1 provided at one end in the width direction of the mounting substrate A and a guide assembly C2 provided at the other end. The linear drive unit C1 can directly drive the slide B to move up and down, and the guide assembly C2 is used to make the up and down movement of the slide B on the mounting substrate A smoother. The advantage of this design is that by providing the linear drive unit C1 and the guide assembly C2 at both ends, mounting space can be left in the center of the slide B, which is convenient for mounting the massage member. It has the advantage of a rational layout and compactness, which is advantageous for designing a thin device.

[0038] Furthermore, as shown in Figures 13 and 14, the linear drive unit C1 includes a first threaded rod C11 extending in the height direction of the mounting base A, a nut C12 covering the first threaded rod C11, and a first motor C13 that drives and rotates the nut C12. The first threaded rod C11 is located at the left end of the mounting base A, and both ends of the first threaded rod C11 are fixedly supported on the mounting base A via a support base C3. The first motor C13 is fixedly mounted on the slide B, and the first motor C13 drives and rotates the nut C12, moving the nut C12 to cause a helical vertical movement of the first threaded rod C11 in the axial direction, thereby moving the first motor C13 and the entire slide B to perform a vertical movement. Since the first threaded rod C11 is positioned off-center, there is a tendency for play to occur in the slide B. Therefore, in combination with the guide assembly C2 at the right end, this play in the slide B can be absorbed, ensuring the stability of the slide B's vertical movement. Furthermore, by fixing the first threaded rod C11 in place, more stable support can be provided to the slide B.

[0039] As shown in Figures 4 and 13, the guide assembly C2 includes a linear guide C21 fixed to the right end of the mounting base A, the linear guide C21 extending in the height direction of the mounting base A, and as shown in Figure 15, a second wheel C22 is provided at a position corresponding to the linear guide C21 at the bottom of the slide B, which is in slidable contact with the linear guide C21.

[0040] Furthermore, as shown in Figures 13 and 15, a long guide groove C23 is provided on the linear guide C21, and a wheel bracket C24 is provided at the bottom of the slide B, extending downward into the guide groove C23. Two second wheels C22 are arranged on one wheel bracket C24, and the two second wheels C22 are rotatably mounted on both sides of the wheel bracket C24. In this embodiment, at least two sets of wheel brackets C24 are provided. This design has the advantage of increasing the smoothness of the sliding of the slide B and further reducing costs.

[0041] As shown in Figure 15, a plurality of third wheels B5 are rotatably provided at the bottom of slide B, which slidably contact the mounting base plate A. The third wheels B5 can further enhance the smoothness of the sliding of slide B.

[0042] The above description is merely a preferred embodiment of the present invention, and those skilled in the art can make various similar expressions under the teachings of the present invention, provided that they do not depart from the spirit of the invention and the claims, and any such modifications will fall within the scope of protection of the present invention.
