[0004] In view of this, one of the purposes of the present invention is to provide a massage device that can massage the user's waist and back area in a massage manner, and has the advantage of good massage effect.

[0005] To achieve the above purpose, the technical solution of this utility model is as follows:

[0006] A massage device, the key of which is to include:

[0007] A mounting base, wherein the mounting base is provided with a slide seat that slides along its height direction;

[0008] a first driving mechanism for driving the slide to move up and down along the mounting base;

[0009] A rotating bracket is rotatably mounted relative to the slide, and one end of the rotating bracket away from its rotation center is provided with two sets of massage heads, the two sets of massage heads are respectively used to act on the meridians on both sides of the spine of the user's back; and

[0010] The second driving mechanism is used to drive the rotating bracket to rotate so that the two groups of massage heads can be pushed outward or retracted inward relative to the mounting base plate.

[0011] With this structure, when the massage function is not in use, the massage heads and rotating bracket are retracted into the backrest, preventing them from protruding from the backrest and causing discomfort on the user's waist, thus ensuring normal riding comfort. When the massage function is in use, the second drive mechanism drives the rotating bracket to rotate outward, allowing the massage heads at the distal end of the rotating bracket to push toward the front of the backrest and act on the occupant's waist and back. The first drive mechanism drives the slide to move up and down, driving the two massage heads to move up and down along the meridians on both sides of the occupant's spine, thereby simulating a reciprocating massage technique.

[0012] Preferably: the second driving mechanism includes a support part slidably arranged on the slide seat, and a thrust assembly for controlling the sliding of the support part. The rotating bracket and the support part are connected by a connecting rod. One end of the connecting rod is hinged to the rotating bracket, and the other end is hinged to the support part.

[0013] Preferably, the thrust assembly includes a limit block abutting against the support portion, and a driving component driving the limit block to move along the sliding direction of the support portion; an elastic element is provided between the slide and the support portion, and the elastic element applies a force that causes the support portion to abut against the limit block; when the massage head is pressed by an external force, the support portion can overcome the resistance of the elastic element and slide to cause the massage head to move toward the slide.

[0014] Preferably, the elastic element is a compression spring, which abuts between the support portion and the end of the slide seat. When the limit block moves toward the compression spring, it can force the compression spring to store force through the support portion. When the limit block moves away from the support portion, it can release the elastic potential energy of the compression spring.

[0021] The second purpose of the present utility model is to provide a car seat, the key of which is that it comprises a backrest in which the above-mentioned massage device is integrated.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] 1. The massage device provided by the present invention is integrated into the backrest of a car seat. When the massage function is not in use, the massage head and the rotating bracket are stored in the backrest to prevent them from protruding from the backrest and causing discomfort to the user's waist, thereby ensuring normal riding comfort. When the massage function is in use, the second drive mechanism drives the rotating bracket to rotate outward so that the massage head at the far end of the rotating bracket can be pushed out to the front of the backrest and act on the occupant's waist and back.

[0042] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0043] like Figure 16 As shown, a car seat includes a backrest F with an integrated massage device installed within it. This massage device can massage the meridians on both sides of the user's back spine using massage techniques. In combination with the massage device shown in Figures 1 to 3, the massage device includes a mounting base A, a slide B mounted on the mounting base A that slides along its height, 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. Two sets of massage heads B2 are mounted on one end of the rotating bracket, distal from its rotation center. These two sets of massage heads B2 are respectively designed to act on the meridians on both sides of the user's back spine. A second drive mechanism D is installed on the slide B, which can rotate the rotating bracket to push the massage heads B2 outward or retract them relative to the mounting base A. In this embodiment, the massage heads B2 are rolling massage heads.

[0044] Based on this, when the massage function is not in use, the massage head B2 and the rotating bracket are stored in the backrest, that is, the massage head B2 is closer to the slide B, avoiding the massage head B2 protruding from the backrest and causing discomfort to the user's waist, ensuring normal riding comfort. When the user needs to use the massage head B2 for massage, the second drive mechanism D drives the rotating bracket to rotate outward so that the massage head B2 at the far end of the rotating bracket can be pushed out to the front side of the backrest F (refer to Figure 16 ) and acts on the occupant's lower back. Subsequently, the first drive mechanism C drives the slide B to move up and down, driving the two sets of massage heads B2 to move up and down along the meridians on both sides of the occupant's spine, simulating a reciprocating massage technique with the advantage of excellent massage effect. Furthermore, by controlling the outward rotation angle of the rotating bracket, the massage depth of the massage heads B2 can be adjusted, ensuring comprehensive relaxation for users of all body types.

[0045] In specific applications, the rotating bracket can be designed as an integrated rotating bracket or two sets of independent massage head arms B1 according to needs. In this embodiment, the rotating bracket includes two sets of massage head arms B1 symmetrically arranged along the width direction of the slide B, and the two sets of massage heads B2 are respectively arranged at the distal ends of the two sets of massage head arms B1. The two sets of massage head arms B1 are rotatably installed on the slide B through a rotating shaft at one end away from the massage head B2.

[0046] Further, combined with Figures 3 to 5As shown, 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 massage head arm B1 is connected to the support portion D4 via a connecting rod D5. One end of the connecting rod D5 is hinged to the middle portion of the massage head arm B1, and the other end is hinged to the support portion D4. The support portion D4 slides, driving the massage head arm B1 to rotate via the connecting rod D5. The thrust assembly drives the support portion D4 upward, driving the massage head arm B1 to rotate outward synchronously via the connecting rod D5. The thrust assembly drives the support portion D4 downward, driving the massage head arm B1 to rotate inward synchronously with the linkage of the connecting rod D5, thereby retracting the massage head B2 toward the slide B. The two sets of massage head arms B1 are driven in the same manner, so only one set of massage head arms B1 will be used as an example for detailed description.

[0047] Please refer to Figure 6 and 7 The thrust assembly includes a stopper D2 abutting the support portion D4 and a drive component D3 that drives the stopper D2 in the sliding direction of the support portion D4. An elastic element D1 is disposed between the slide B and the support portion D4, exerting a force that forces the support portion D4 against the stopper D2. When the massage head B2 is subjected to external pressure, the support portion D4 overcomes the resistance of the elastic element D1 and slides toward the slide B. With this design, when a user desires to use the massage head B2 for massage, the drive component D3 drives the stopper D2 away from the support portion D4. During this process, because the elastic element D1 exerts a force that continuously presses the support portion D4 against the stopper D2, the support portion D4 moves synchronously with the stopper D2. Consequently, under the linkage action of the connecting rod D5, the massage head arm B1 is driven to rotate outward, allowing the massage head B2 at the distal end of the massage head arm B1 to be ejected toward the front of the backrest A. After the massage is completed, the driving component D3 drives the limit block D2 to move toward the support part D4. At this time, the limit block D2 pushes the support part D4 to overcome the resistance of the elastic element D1 and slide, thereby driving the massage head arm B1 to rotate inward under the linkage action of the connecting rod D5, so that the massage head B2 is retracted toward the slide B.

[0048] In addition, based on this assembly method, the massage head B2 also has a passive collapse function when in operation. The specific process is as follows: when the massage head B2 is in operation, if the vehicle collides or other emergencies occur and the massage head B2 is subjected to external force, the support portion D4 can overcome the resistance of the elastic element D1 and slide. Under the linkage action of the connecting rod D5, it can drive the massage head B2 to quickly retract toward the slide B, effectively preventing the massage head B2 from causing harm to the human body and improving the safety of the massage. When the external force disappears, the elastic element D1 resets, pushing the support portion D4 to slide, and then driving the massage head arm B1 and massage head B2 to automatically return to the working position. This design can protect the massage head B2 from damage, save costs, and eliminate the trouble of replacing parts, which has the advantage of good practicality.

[0049] Furthermore, the elastic element D1 can be a compression spring, a tension spring, a torsion spring, a leaf spring, a spring, etc. In this embodiment, the elastic element D1 is a compression spring. Figure 6 and 7 The compression spring abuts between the support portion D4 and the lower end of the slide B. The limit block D2 moves downward along the height direction of the slide B, that is, moves toward the compression spring, pushing the support portion D4 downward to compress the compression spring, forcing the compression spring to accumulate force. The downward movement of the support portion D4 can drive the massage head arm B1 to rotate toward the slide B via the connecting rod D5. When the limit block D2 moves away from the support portion D4, that is, moves upward, the elastic potential energy of the compression spring is released. The thrust generated by the compression spring causes the support portion D4 to move synchronously with the limit block D2, thereby driving the massage head arm B1 to rotate outward via the connecting rod D5. In this state, when the massage head B2 is pressed by external force, the support part D4 can squeeze the compression spring downward, and then drive the massage head arm B1 to quickly retract toward the slide B through the connecting rod D5; when the external force disappears, the compression spring can release energy and push the support part D4 to move upward until the support part D4 abuts against the limit block D2. At this time, the massage head arm B1 returns to the working position and the massage head B2 is not damaged by external force.

[0050] like Figure 6 and 7 As shown, a slide bar D6 is fixed to the slide B, extending along its height. The elastic element D1, support portion D4, and stopper D2 are sequentially mounted on the slide bar D6 from bottom to top. The support portion D4 and stopper D2 are able to slide up and down relative to the slide bar D6. This design ensures the reliable installation and movement of the elastic element D1, support portion D4, and stopper D2.

[0051] Further, such as Figure 5 and Figure 9As shown, there are two groups of sliding rods D6, and the two groups of sliding rods D6 are symmetrically arranged along the width direction of the slide B. One group of sliding rods D6 corresponds to one group of massage head arms B1, and two groups of elastic elements D1 and connecting rods D5 are also provided. The two groups of elastic elements D1 are respectively mounted on the two sliding rods D6, and the two ends of the limit block D2 and the two ends of the support part D4 are respectively slidably connected to the two sliding rods D6. The two connecting rods D5 are symmetrically arranged on the sides of the two groups of massage head arms B1.

[0052] Please refer to Figure 9 The drive component D3 includes a second motor D31 fixed to the slide B and a second screw D32 driven by the second motor D31. The second screw D32 extends along the height of the slide B and is positioned between the two sets of slide rods D6. The middle portion of the limit block D2 is threadedly mounted on the second screw D32. The second motor D31 drives the limit block D2 downward, which drives the support portion D4 to simultaneously compress the two sets of elastic elements D1, thereby simultaneously retracting the two sets of massage head arms B1 inward, ensuring the synchronization of the movement of the two sets of massage head arms B1. This layout also improves the overall structural compactness, allowing the mechanism to be better integrated into the vehicle seat backrest.

[0053] Depend on Figure 9 As can be seen, a mounting base D7 is fixed to the lower end of slide B. The ends of two slide rods D6 are fixedly connected to the widthwise ends of mounting base D7. The lower end of second screw rod D32 is pivotally supported in the center of mounting base D7. On the same slide rod D6, one end of elastic element D1 is supported on mounting base D7, while the other end abuts against the corresponding support portion D4. This design ensures reliable installation.

[0054] Combine Figure 9 and Figure 12 As shown, both ends of the limit block D2 have first connection holes D21, which are respectively slidably mounted on the two sets of slide rods D6. The middle of the limit block D2 is provided with a second connection hole D22, which is threadedly mounted on the second screw rod D32.

[0055] Please refer to Figure 10 and 11 The support portion D4 has two ends with sleeves D41 that slide over the two sets of slide rods D6, with one end of the compression spring resting against the corresponding sleeve D41. A downwardly recessed escape groove D42 is located in the middle of the support portion D4, with the second screw rod D32 positioned above the escape groove D42, further enhancing the compactness of the structure.

[0056] Re-attend Figure 10A first roller D8 is provided on the lower side of the support part D4, which is in sliding contact with the slide B. The first roller D8 increases the smoothness of the support part D4 sliding on the slide B. On the other hand, in the event of a collision, the support part D4 can also smoothly squeeze the compression spring downward to ensure that the massage head arm B1 can be quickly retracted.

[0057] like Figure 13 As shown, the first drive mechanism C includes a linear drive unit C1 positioned at one end of the mounting base A in the width direction, and a guide assembly C2 positioned at the other end. The linear drive unit C1 directly drives the slide B to move up and down, while the guide assembly C2 ensures smoother movement of the slide B on the mounting base A. This design offers the advantage of locating the linear drive unit C1 and guide assembly C2 at both ends, reserving space in the middle of the slide B for mounting massage components. This provides a rational and compact layout, contributing to a slimmer design for the device.

[0058] Furthermore, Figure 13 and 14 As shown, the linear drive unit C1 includes a first screw rod C11 extending in the height direction of the mounting base A, a nut sleeve C12 mounted on the first screw rod C11, and a first motor C13 that drives the nut sleeve C12 to rotate. The first screw rod C11 is located at the left end of the mounting base A, and both ends of the first screw rod C11 are fixedly supported on the mounting base A by support bases C3. The first motor C13 is fixedly mounted on the slide B. The first motor C13 drives the nut sleeve C12 to rotate, which can drive the nut sleeve C12 to move up and down along the axial spiral of the first screw rod C11, thereby driving the first motor C13 and the slide B to move up and down as a whole. Because the first screw rod C11 is offset, the slide B is prone to wobbling clearance. Therefore, the guide assembly C2 at the right end can absorb the wobbling clearance of the slide B and ensure the smoothness of the slide B's lifting and lowering movement. At the same time, by fixing the first screw rod C11, more stable support can be provided for the slide B.

[0059] like Figure 4 and 13 As shown, the guide assembly C2 includes a guide rail C21 fixed to the right end of the mounting base A, and the guide rail C21 extends along the height direction of the mounting base A. As shown in Figure 15, a second roller C22 is provided at the bottom of the slide B corresponding to the position of the guide rail C21, and the second roller C22 is in sliding contact with the guide rail C21.

[0060] Furthermore, Figure 13 and 15As shown, guide rail C21 is provided with a strip-shaped guide groove C23. A roller bracket C24 is provided at the bottom of slide B, extending downward into guide groove C23. Each roller bracket C24 is equipped with two second rollers C22, which are rotatably mounted on either side of roller bracket C24. In this embodiment, at least two sets of roller brackets C24 are provided. This design improves the smoothness of slide B's movement while also offering the advantage of low cost.

[0061] Please refer to Figure 15 The bottom of the slide B is rotatably provided with multiple sets of third rollers B5 that are in sliding contact with the mounting base A. The third rollers B5 can further improve the smoothness of the sliding of the slide B.

[0062] 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. Such changes fall within the scope of protection of the present invention.
