Description

Technical Field

[0001] The present invention relates to the technical field of automobile seats, and more specifically, to a percussion massager and an automobile seat equipped with a percussion massager.

Background Art

[0002] With the progress of science and technology, people's requirements for the comfort of automobile seats are constantly increasing. When passengers who drive or ride for a long time maintain the same posture for a long time, their bodies will become fatigued and their muscles will be prone to stiffness. To solve the problem of fatigue derived from long-term driving or riding, more seats are beginning to be equipped with a massage function.

[0003] In the prior art, massage devices on automobile seats are usually divided into two types: airbag massage and mechanical massage. Among them, the airbag massage adopts a flexible airbag to act on the waist and back areas of the user. The intensity of the massage is relatively low, the massage effect is not good, and it is difficult to relax the user's body thoroughly to the deep part. Many mechanical massage devices directly massage the user's back through a rotatable massage device. The intensity of the massage is greater than that of the airbag massage, but there are also defects such as large volume and complex structure. Furthermore, the conventional airbag massage and mechanical massage mainly imitate the kneading massage technique, and it has become impossible to meet the more diversified massage needs of users. Therefore, in the field of automobile seat massage, the development of more massage methods is required.

Summary of the Invention

Problems to be Solved by the Invention

[0004] In view of this, one of the objectives of the present invention is to provide a percussion massager capable of massaging the waist and back areas of the user in a percussion manner.

Means for Solving the Problems

[0005] To achieve the above objective, the technical method of the present invention is as follows.

[0006] A percussion massage machine is characterized by including a device base for mounting inside a seat backrest, on which two sets of swing arms are rotatably mounted, each having a percussion section at one end away from the pivot point, and a first drive mechanism is provided on the device base for driving the swing arms to reciprocate within a certain range and form a percussion massage at the percussion sections at their ends.

[0007] By adopting the above structure, when the user needs to perform a tapping massage with the tapping section, the first drive mechanism drives two sets of swing arms, which swing back and forth toward the front of the backrest, i.e., toward the user's waist and back, moving the tapping sections at the ends of the two sets of swing arms, thereby performing a reciprocating tapping massage on the user's back.

[0008] Preferably, the first drive mechanism includes a first rotating shaft provided on the device base and a first drive assembly that drives and rotates the first rotating shaft, on which two transmission sleeves are rotatably covered, wherein the centerlines of the two transmission sleeves are both eccentrically positioned with respect to the centerline of the first rotating shaft, the two transmission sleeves are arranged correspondingly below two sets of swing arms, and a transmission rod is provided between the transmission sleeves and the corresponding swing arms, with one end hinged to the transmission sleeve and the other end hinged to the center of the swing arm. The first drive assembly can drive the first rotating shaft to rotate and move the swing arm under the eccentric transmission of the transmission sleeve to cause it to reciprocate within a certain range.

[0009] Preferably, the two sets of transmission sleeves are oriented in opposite eccentric directions.

[0010] Preferably, a support member on which the first rotating shaft is rotatably covered and a thrust mechanism for controlling the sliding of the support member are slidably mounted on the device base, and the sliding of the support member moves the swing arm via a transmission rod, causing it to rotate around its pivot point, and the striking part to move in a direction away from or near the device base.

[0011] Preferably, the thrust mechanism includes a limiter that abuts the support member and a second drive assembly that drives the limiter to move in the sliding direction of the support member, wherein an elastic element is provided between the device base and the support member to apply a force that causes the support member to abut the limiter, and when the striking portion is compressed by an external force, the support member can slide over the resistance of the elastic element and move the striking portion toward the device base.

[0012] Preferably, the elastic element is a compression spring that abuts between the support member and the end of the device base. When the limiter moves toward the compression spring, force can be stored in the compression spring via the support member. When the limiter moves toward the support member, the elastic potential energy of the compression spring can be released. The thrust generated by the compression spring can move the support member simultaneously with the limiter.

[0013] Preferably, a guide rod extending in the height direction is fixed to the device base, the elastic element, support member and limiter are sequentially installed on the guide rod from bottom to top, and the support member and limiter can slide up and down relative to the guide rod.

[0014] Preferably, the device base includes a mounting plate for installation inside a seat backrest and a support plate slidably connected on the mounting plate, the support plate sliding in the height direction of the mounting plate, the first drive mechanism and two sets of swing arms provided on the support plate, and a third drive mechanism provided on the mounting plate for driving the support plate to slide in the height direction of the mounting plate.

[0015] Preferably, the third drive mechanism includes a linear drive assembly provided at one end of the mounting plate in the width direction for driving the support plate to move up and down, and a guide assembly provided at the other end for guiding the up and down movement of the support plate.

[0016] Another object of the present invention is to provide an automobile seat including a backrest, wherein the above-mentioned tapping massage machine is integrated and mounted inside the backrest. [Effects of the Invention]

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

[0018] 1. By employing the percussion massager provided in the present invention, after the percussion massager is installed and integrated inside the backrest A of a car seat, when the user needs to perform a percussion massage with the percussion part, the first drive mechanism drives two sets of swing arms to swing back and forth toward the front of the backrest, i.e., toward the user's waist and back, moving the percussion parts at the ends of the two sets of swing arms, thereby performing a reciprocating percussion massage on the user's back. This allows relaxation to be achieved through percussion massage using the meridians on both sides of the spine in the user's back.

[0019] 2. By adopting the percussion massage machine provided in the present invention, an eccentric transmission system can be used to convert the rotational motion of the eccentric shaft section into the forward and backward oscillation of the percussion section. This system has advantages such as a simple structure, small volume, low manufacturing cost, high efficiency, and high-precision transmission.

[0020] 3. The tapping massage machine provided in this invention combines pinpoint tapping, moving tapping, and moving acupressure massage functions, providing not only superior massage effects but also offering users a variety of massage functions to choose from, thereby enhancing the user experience.

[0021] 4. By adopting the percussion massager provided by the present invention, it is realized that the percussion part is stored inside the backrest when it is not operating, avoiding protruding from the backrest and causing discomfort to the user's waist, not only ensuring the comfort of normal riding, but also when massage is needed, the percussion part can be deployed in a state of protruding from the backrest to realize the massage function. In addition, when a collision accident occurs, it is possible to realize the recoverable crushing of the percussion part and enhance the safety of the massage.

[Modes for carrying out the invention]

[0023] The present invention will be further described below with reference to examples and drawings.

[0024] As shown in Figure 4, the percussion massager includes a device base B. In this embodiment, the device base B includes a mounting plate 1 for installation inside the seat backrest and a support plate 2 slidably mounted on the mounting plate 1. The support plate 2 can slide in the height direction of the mounting plate 1. As can be seen in combination with Figure 5, a second rotation axis B1 is provided on the support plate 2, arranged in the width direction. Two sets of swing arms B2 are rotatably mounted on the second rotation axis B1. The two sets of swing arms B2 are arranged symmetrically, and each set of swing arms B2 has a percussion section B3 at one end away from the second rotation axis B1. The percussion section B3 has a spherical structure. A first drive mechanism C is further provided on the support plate 2 to drive the swing arms B2 to reciprocate within a certain range and to form a percussion massage at the percussion section B3 at the end.

[0025] As shown in Figures 3 and 4, after the percussion massager is installed inside the backrest A of the car seat, when the user needs to perform a percussion massage with the percussion section B3, the first drive mechanism C drives two sets of swing arms B2 to swing back and forth against the front of the backrest A, i.e., against the user's waist and back H, moving the percussion sections B3 at the ends of the two sets of swing arms B2, allowing for a reciprocating percussion massage on the user's back. This allows relaxation to be achieved by using the meridians on both sides of the spine in the user's back.

[0026] Furthermore, as shown in Figures 4 and 8, the first drive mechanism C includes a first rotating shaft C1 provided on the support plate 2 and a first drive assembly C2 that drives and rotates the first rotating shaft C1, the first rotating shaft C1 being located below the two sets of swing arms B2. Two transmission sleeves C3 are rotatably mounted over the first rotating shaft C1, and the two transmission sleeves C3 are positioned correspondingly below the two sets of swing arms B2, and in this embodiment, the centerlines of the two transmission sleeves C3 are both eccentrically positioned with respect to the centerline of the first rotating shaft C1. A transmission rod C4 is provided between the transmission sleeve C3 and the corresponding swing arm B2, with one end hinged to the transmission sleeve C3 and the other end hinged to the center of the swing arm B2. The first drive assembly C2 drives and rotates the first rotating shaft C1, and under the eccentric transmission operation of the transmission sleeve C3, the transmission rod C4 can move the corresponding swing arm B2 and oscillate back and forth within a certain range, thereby realizing a reciprocating tapping massage of the tapping section B3 against the user's back. In this embodiment, the first drive assembly C2 drives and rotates the first rotating shaft C1 in a motor direct drive manner.

[0027] Furthermore, as shown in Figures 8 and 11, the first rotating shaft C1 has an eccentric shaft section C11 at the position of the corresponding transmission sleeve C3, and the transmission sleeve C3 is rotatably mounted over the corresponding eccentric shaft section C11. When the eccentric shaft section C11 rotates with the first rotating shaft C1, the rotational motion of the eccentric shaft section C11 can be converted into the back-and-forth oscillation of the striking section B3 through the mutual engagement of the transmission sleeve C3, the transmission rod C4, and the swing arm B2. This allows the transmission rod C4 to move the corresponding swing arm B2, enabling a small range of reciprocating oscillation, and has the advantages of a simple structure and small volume. In addition to the embodiment described above, a cam with another projection structure may be provided at the position of the corresponding transmission sleeve C3 on the first rotating shaft C1, and the transmission sleeve C3 can be rotatably mounted over the cam, and the cam can rotate, similarly causing the swing arm B2 to oscillate.

[0028] To increase the flexibility of the transmission of the swingarm B2, a ball joint is used between the transmission rod C4 and the swingarm B2.

[0029] As can be seen from Figure 11, the two sets of eccentric axis sections C11 are eccentric in opposite directions with respect to the centerline of the first rotation axis C1. In the initial state, the centerline m of the left eccentric axis section C11 is eccentrically positioned downward with respect to the centerline n of the first rotation axis C1, and the centerline k of the right eccentric axis section C11 is eccentrically positioned upward with respect to the centerline n of the first rotation axis C1. With this design, when the first rotation axis C1 rotates, the two sets of eccentric axis sections C11 cause the two sets of swing arms B2 to swing in different directions, creating a reciprocating, alternating tapping massage on the user's back with the two tapping sections B3, thereby improving the massage experience.

[0030] As shown in Figure 6, a third drive mechanism E is provided on the mounting plate 1, which drives the support plate 2 to move up and down in the height direction of the mounting plate 1. When the tapping section B3 performs a tapping massage on the user's waist or back, the third drive mechanism E drives the support plate 2 to move up and down, moving the two tapping sections B3 up and down along the meridians on both sides of the user's spine. This mimics a moving tapping massage method, enriches the massage function, and enhances the massage effect.

[0031] Furthermore, as shown in Figure 5, the third drive mechanism E includes a linear drive assembly E1 provided at one end of the mounting plate 1 in the width direction and a guide assembly E2 provided at the other end. The linear drive assembly E1 can drive the support plate 2 to move up and down, and the guide assembly E2 guides the up and down movement of the support plate 2, making the up and down movement of the support plate 2 on the mounting plate 1 smoother. The advantage of this design is that by providing the linear drive assembly E1 and the guide assembly E2 at both ends, mounting space can be left in the center of the support plate 2, which is convenient for mounting the massage member. It also has the advantage of a rational and compact layout, which helps to make the product thinner and integrate it inside the seat backrest in a more compact manner.

[0032] As shown in Figure 5, the linear drive assembly E1 includes a first threaded rod E11 extending in the height direction of the mounting plate 1, a nut E12 covering the first threaded rod E11, and a first motor E13 that drives and rotates the nut E12, the first threaded rod E11 being located at the left end of the mounting plate 1. As can be seen in Figure 14, both ends of the first threaded rod E11 are fixedly supported on the mounting plate 1 via a support base E3. The first motor E13 is fixedly mounted on the support plate 2, and the first motor E13 drives and rotates the nut E12, moving the nut E12 and causing the first threaded rod E11 to perform a spiral vertical movement in the axial direction, thereby moving the first motor E13 and the entire support plate 2 to perform a vertical movement. Since the first threaded rod E11 is positioned off-center, the support plate 2 is prone to wobbling. Therefore, together with the guide assembly E2 at the right end, it is possible to absorb the wobbling of the support plate 2 and ensure the stability of the support plate 2's vertical movement. Furthermore, by fixing the first threaded rod E11 in place, even more stable support can be provided to the support plate 2.

[0033] Furthermore, as shown in Figure 5, the guide assembly E2 includes a linear guide E21 fixed to the right end of the mounting plate 1. The linear guide E21 extends in the height direction of the mounting plate 1, and as shown in Figures 15 and 16, a second wheel E22 is provided at a position corresponding to the linear guide E21 at the bottom of the support plate 2, which slidably contacts the bottom of the linear guide E21. This design enhances the smoothness of the sliding of the support plate 2 and also has the advantage of being cost-effective.

[0034] As shown in Figure 15, a plurality of third wheels 21 are rotatably provided on the bottom of the support plate 2, which slidably contact the mounting plate 1. The third wheels 21 can further enhance the smoothness of the sliding of the support plate 2.

[0035] As shown in Figures 4 and 7, a support member B4 and a thrust mechanism D that controls the sliding of the support member B4 are slidably mounted on the support plate 2, and the first rotating shaft C1 is rotatably mounted over the support member B4. When the support member B4 slides, the first rotating shaft C1 can be moved, which in turn moves the swing arm B2 via the transmission rod C4, causing it to rotate around its pivot point, and allowing the tapping section B3 to move away from or closer to the device base B. Based on this, when the massage function is not in use, the tapping section B3 and the swing arm B2 are retracted into the backrest, that is, the tapping section B3 is positioned closer to the support plate 2 (see Figure 5), preventing the tapping section B3 from protruding from the backrest and causing discomfort to the user's waist, thus ensuring normal riding comfort. When the user needs to perform a tapping massage using the tapping section B3, the support member B4 slides to move the swing arm B2 and rotate it outward, causing the tapping section B3 at the end of the swing arm B2 to protrude in front of the backrest A (see Figure 3), allowing it to act on the rider's waist and back. Subsequently, the first drive assembly C2 drives the first rotation axis C1 to rotate it, causing the tapping section B3 at the end to form a reciprocating tapping massage against the user's back. After the massage is finished, the thrust mechanism D drives the support member B4 to slide, rotating the swing arm B2 toward the support plate 2, thereby retracting the tapping section B3 toward the support plate 2. In addition, by controlling the angle at which the swing arm B2 rotates outward, the depth of the tapping massage of the tapping section B3 can be adjusted, allowing users of various body types to obtain an effective massage.

[0036] Furthermore, as shown in Figures 9 and 10, the thrust mechanism D includes a limiter D2 that contacts the support member B4, and a second drive assembly D3 that drives the limiter D2 to move in the sliding direction of the support member B4. An elastic element D1 is provided between the support plate 2 and the support member B4, applying a force that causes the support member B4 to contact the limiter D2. When the striking portion B3 is subjected to an external force and compressed, the support member B4 can slide, overcoming the resistance of the elastic element D1, and move the striking portion B3 toward the support plate 2. With this design, when the user needs to use the striking portion B3 to perform a massage, the second drive assembly D3 drives the limiter D2 to move it away from the support member B4. During this process, a force is applied to the elastic element D1 that keeps the support member B4 in contact with the limiter D2. As a result, the support member B4 moves simultaneously with the limiter D2, and the first rotation axis C1 moves simultaneously. This, under the interlocking action of the transmission rod C4, moves the swing arm B2, causing it to rotate outward relative to the second rotation axis B1, and allowing the striking portion B3 at the end of the swing arm B2 to protrude forward to the backrest A. After the massage is completed, the second drive assembly D3 drives the limiter D2 to move it toward the support member B4. At this time, the limiter D2 pushes the support member B4, overcoming the resistance of the elastic element D1 and sliding, which, under the interlocking action of the transmission rod C4, moves the swing arm B2 inward, allowing the striking portion B3 to be housed toward the support plate 2.

[0037] Under this structural design, the striking part B3 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 striking part B3 is in operation, and the striking part B3 is compressed by an external force, the support member B4 can overcome the resistance of the elastic element D1 and move the first rotation axis C1 and slide, and under the interlocking action of the transmission rod C4, the striking part B3 is moved and quickly retracted toward the support plate 2, effectively preventing the striking part B3 from causing injury to the human body and increasing the safety of the massage. When the external force disappears, the elastic element D1 returns to its original position and pushes and slides the support member B4, thereby moving the swing arm B2 and the striking part B3 and automatically returning them to the operating position. With this design, the striking part B3 is protected from damage, costs are saved, the hassle of replacing parts is eliminated, and it has the advantage of being highly practical.

[0038] 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. As shown in Figures 9 and 10, the compression spring abuts between the support member B4 and the lower end of the support plate 2, and the limiter D2 moves downward in the height direction of the support plate 2, that is, moves in a direction closer to the compression spring, pushing the support member B4 and compressing the compression spring downward, allowing the compression spring to store force. When the support member B4 moves downward, it moves the swing arm B2 via the transmission rod C4 and rotates it in the direction of the support plate 2. When the limiter D2 moves away from the support member B4, 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 member B4 simultaneously with the limiter D2, thereby moving the swing arm B2 via the transmission rod C4 and rotating it outward. In this state, when the striking part B3 is compressed by an external force, the support member B4 pushes the compression spring downward, thereby moving the swing arm B2 via the transmission rod C4 and quickly retracting it toward the support plate 2. When the external force disappears, the compression spring releases energy, pushing the support member B4 and moving it upward until it contacts the limiter D2. At this point, the swing arm B2 returns to its operating position, and the striking part B3 is not damaged by the external force.

[0039] As shown in Figure 7, a guide rod D4 extending in the height direction is fixed to the support plate 2, and the elastic element D1, support member B4, and limiter D2 are sequentially installed on the guide rod D4 from bottom to top, and the support member B4 and limiter D2 can slide up and down relative to the guide rod D4. This design ensures the reliability of the mounting and movement of the elastic element D1, support member B4, and limiter D2.

[0040] Furthermore, as shown in Figure 7, the second drive assembly D3 includes a second motor D31 fixed to the support plate 2 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 support plate 2, and the limiter D2 is covered on the second threaded rod D32 with threads. The second motor D31 drives and rotates the second threaded rod D32, allowing the limiter D2 to move along the second threaded rod D32. To ensure the overall structure is compact and the support member B4 receives uniform force, there are two sets of guide rods D4, which are arranged symmetrically in the width direction of the support plate 2, and the second threaded rod D32 is located between the two sets of guide rods D4. Elastic elements D1 are mounted on both sets of guide rods D4, and both ends of the limiter D2 and both ends of the support member B4 are slidably connected to the two guide rods D4. The second motor D31 can drive the limiter D2 downward, move the support member B4, and simultaneously press the two sets of elastic elements D1, thereby moving the two sets of swing arms B2 inward and ensuring the synchronization of the movement of the two sets of swing arms B2.

[0041] As can be seen in Figure 7, a mounting base D5 is fixed to the lower end of the support plate 2, and the ends of the two guide rods D4 are both fixedly connected to both ends of the mounting base D5 in the width direction, and the lower end of the second threaded rod D32 is rotatably supported in the center of the mounting base D5. On the same guide rod D4, one end of the elastic element D1 is supported on the mounting base D5, and the other end is in contact with the support member B4. This consideration ensures the reliability of the mounting.

[0042] As shown in Figures 7 and 13, 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 guide rods D4. 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.

[0043] As shown in Figures 7 and 12, covering portions B41 are provided at both ends of the support member B4, which are slidably mounted over two sets of guide rods D4, and one end of the compression spring abuts against the corresponding covering portion B41. Two sets of engagement portions B42 are further provided on the support member B4, and as shown in Figure 8, the first rotating shaft C1 passes through the two engagement portions B42, and the central part of the first rotating shaft C1 is rotatably supported on the two engagement portions B42. After the first rotating shaft C1 is mounted on the engagement portions B42, the first rotating shaft C1 is positioned above the two guide rods D4.

[0044] Furthermore, as shown in Figures 8 and 12, the support member B4 has a downwardly recessed avoidance groove B43 in the center, and the second threaded rod D32 is located above the avoidance groove B43, further enhancing the compactness of the structure. A first wheel B44 is provided on the lower side of the support member B4, which slidably contacts the support plate 2. The first wheel B44 increases the smoothness of the support member B4 sliding on the support plate 2, while also ensuring that in the event of a collision, the support member B4 can smoothly push the compression spring downward, allowing the swing arm B2 to be quickly retracted.

[0045] The percussion massager provided in this embodiment can not only realize the function of percussion massage but can also mimic mobile acupressure massage. Specifically, it works as follows: The support member B4 slides, moving the swing arm B2 to rotate outward, so that the percussion part B3 at the end of the swing arm B2 protrudes to the front of the backrest A and acts on the user's waist and back. The third drive mechanism E drives the support plate 2 to move up and down along the mounting plate 1, moving the percussion part B3 up and down along the meridians on both sides of the spine on the user's back, thereby mimicking the massage function of mobile acupressure.

[0046] As shown in Figure 1, this embodiment further provides an automobile seat including a backrest A in which the aforementioned percussion massager is integrated and mounted inside, and when the percussion massager is in operation, it can perform massages such as pinpoint percussion, moving percussion, and moving acupressure on the user. When installed, a mounting plate F is fixedly installed at a position relative to the mounting plate 1 on the front side of the backrest A to protect and shield the percussion massager, and a second opening F1 is provided on the mounting plate F to prevent the percussion section B3 from performing moving percussion massage (see Figure 2). Also, as shown in Figures 14 and 17, a support 22 that protrudes forward is mounted on the support plate 2, and a damper G is fixedly connected to the support 22. The damper G can cover and shield the support plate 2, and a first opening G1 is provided in the center of the damper G to prevent the outward protrusion and inward housing of the two percussion sections B3. Furthermore, a fourth wheel G2 is distributed on the damper G, and each of the fourth wheels G2 is in slidable contact with the surface of the mounting plate F.

[0047] 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 and claims of the present invention, and any such modifications will fall within the scope of protection of the present invention.
