[0016] The beneficial effects of the embodiments of the present invention are:

[0017] The massage device of the present invention includes a housing, a robotic arm, a connecting rod, and a drive mechanism. The robotic arm is rotatably connected to the housing. One end of the robotic arm is provided with a massage head, and the other end is hinged to the connecting rod. The connecting rod is driven by the drive mechanism. The drive mechanism can drive the connecting rod to push the robotic arm so that the massage head extends or retracts into the housing. The drive mechanism and the connecting rod can be selectively connected or disconnected. The drive mechanism drives the connecting rod and the robotic arm to move, thereby allowing the massage head to extend or retract into the housing. In emergency situations such as car collisions, the transmission relationship between the drive mechanism and the connecting rod is broken, that is, the drive mechanism no longer constrains the connecting rod, releasing the restriction of the drive mechanism on the massage head, thereby achieving the collapse of the massage head. The present invention can cause the massage head to collapse instantly in emergency situations such as car collisions, preventing injury to the human body. Attached Figure Description

[0031] First Embodiment

[0032] Please refer to Figure 1 This embodiment provides a massage device 100, which includes a housing 10, a robotic arm, a connecting rod, and a drive mechanism 40. The robotic arm is rotatably connected to the housing 10. One end of the robotic arm is provided with a massage head 23, and the other end is hinged to the connecting rod. The connecting rod is driven by the drive mechanism 40. The drive mechanism 40 can drive the connecting rod to push the robotic arm so that the massage head 23 extends or retracts into the housing 10. The drive mechanism 40 and the connecting rod can be selectively driven or disconnected.

[0033] Specifically, the robotic arms include a first robotic arm 21 and a second robotic arm 22 hinged together. The linkages include a first link 31 and a second link 32. Both the first robotic arm 21 and the second robotic arm 22 are equipped with massage heads 23. The first robotic arm 21 is hinged to the first link 31. The second robotic arm 22 is hinged to the second link 32. The drive mechanism 40 includes a slider 46, which can move towards or away from the first robotic arm 21. Both the first link 31 and the second link 32 are connected to the slider 46. It can be understood that the drive mechanism 40 drives the slider 46 to slide, thereby driving the first robotic arm 21 and the second robotic arm 22 to move via the first link 31 and the second link 32, thus achieving the raising and lowering of the massage heads 23.

[0034] Please refer to Figure 3The drive mechanism 40 also includes a fixed plate 41, a guide rod 42, a bushing 43, an elastic element 44, a lead screw 47, and a motor 48. The slider 46 is connected to the connecting rod and can slide relative to the housing 10. The fixed plate 41 is fixedly connected to the housing 10. The guide rod 42 is fixedly connected to the fixed plate 41. The bushing 43 is fixedly connected to the slider 46 and can slide along the guide rod 42. The elastic element 44 is disposed between the fixed plate 41 and the bushing 43. The lead screw 47 and motor 48 include a lead screw 47 and a motor 48. The lead screw 47 is fixedly connected to the fixed plate 41 and parallel to the guide rod 42. The motor 48 is fixedly connected to the slider 46. A retaining sleeve 45 is provided on the guide rod 42. The retaining sleeve 45 is fixed between the fixed plate 41 and the guide rod 42. The elastic element 44 is disposed between the retaining sleeve 45 and the bushing 43. The retaining sleeve 45 is used to abut against the elastic element 44 to prevent the elastic element 44 from slipping. Optionally, in this embodiment, the elastic element 44 is a spring. The two ends of the spring abut against the retaining sleeve 45 and the bushing 43, respectively.

[0035] Understandably, the motor 48 works in conjunction with the lead screw 47, which is fixed to the fixed plate 41. When the motor 48 rotates, it can move along the lead screw 47, thereby driving the slider 46 to move. The slider 46 drives the first connecting rod 31 and the second connecting rod 32 to move, thereby causing the first robotic arm 21 and the second robotic arm 22 to rotate relative to each other, thus realizing the lifting and lowering of the massage head 23.

[0036] In order to allow the transmission relationship between the drive mechanism 40 and the connecting rod to be selectively disconnected, in this embodiment, the lead screw 47 is connected to the fixed plate 41 via an explosive assembly 50. The explosive assembly 50 can be selectively disconnected.

[0037] Please refer to Figure 5 Specifically, the explosive assembly 50 includes an initiator 51, a bolt head 52, a screw 55, and a nut. The initiator 51, bolt head 52, screw 55, and lead screw 47 are connected in sequence. The bolt head 52 and the nut are located on opposite sides of the fixing member. Explosive powder 53 is disposed within the screw 55 between the bolt head 52 and the nut. The initiator 51 detonates the explosive powder 53, thereby causing the screw 55 to disconnect.

[0038] Optionally, in this embodiment, the screw 55 has a notch 54 at the location where the gunpowder 53 is placed. The notch 54 makes it easier for the screw 55 to break, while ensuring that the break position of the screw 55 is fixed.

[0039] Understandably, when the motor 48 moves to the left, it lifts the massage head 23 via the slider 46. At this time, the bushing 43, which is fixedly connected to the slider 46, slides to the left on the guide rod 42, and the elastic element 44 is in a compressed state. When a sudden situation such as a car collision occurs, the screw 55 disconnects, thereby disconnecting the lead screw 47 and the fixing plate 41, releasing the constraint between the lead screw 47 and the motor 48 and the fixing plate 41. The elastic element 44 rebounds, causing the bushing 43 to slide to the right on the guide rod 42. The slider 46, which is fixedly connected to the bushing 43, slides to the right. This achieves the instantaneous collapse of the massage head 23.

[0040] In other embodiments, the explosive assembly 50 may also be located at the first link 31 and the second link 32, and is used to detonate and disconnect the first link 31 and the second link 32 in the event of a vehicle collision. This releases the restriction on the first robotic arm 21 and the second robotic arm 22, at which point the massage head 23 is no longer under force to remain in a protruding state and can collapse to prevent injury to the human body.

[0041] The working principle and process of the massage device 100 provided in this embodiment are as follows:

[0042] Please combine Figures 1-4 Driven by motor 48, slider 46 moves to the left along the lead screw, causing first link 31 to push first robotic arm 21 to rotate clockwise, and causing second link 32 to push second robotic arm 22 to rotate counterclockwise, thereby moving massage head 23 from... Figure 1 The retraction state is changed to Figure 2 The massage head 23 is in a raised state. When it is necessary to retract the massage head 23, the slider 46, driven by the motor 48, moves to the right along the lead screw, causing the first connecting rod 31 to pull the first mechanical arm 21 to rotate counterclockwise, and causing the second connecting rod 32 to pull the second mechanical arm 22 to rotate clockwise, thereby retracting the massage head 23 from its raised state. Figure 2 The convex state turns into Figure 1 The retracted state.

[0043] When the massage head 23 is in the raised state, and an emergency occurs, the elastic element 44 is in the compressed state (e.g., Figure 4 (As shown). The detonator 51 detonates the explosive 53, causing the screw 55 to disconnect, thus separating the lead screw 47 from the fixed plate 41 and releasing the constraint between the lead screw 47, motor 48, and fixed plate 41. The elastic element 44 rebounds, causing the bushing 43 to slide to the right on the guide rod 42. The slider 46, fixedly connected to the bushing 43, slides to the right. The slider 46 drives the massage head 23 to retract downwards, thus achieving instantaneous collapse of the massage head 23.

[0044] The beneficial effects of the massage device 100 provided in this embodiment are:

[0045] The massage device 100 of this embodiment includes a housing 10, a robotic arm, a connecting rod, and a drive mechanism 40. The robotic arm is rotatably connected to the housing 10. One end of the robotic arm is provided with a massage head 23, and the other end is hinged to the connecting rod. The connecting rod is driven by the drive mechanism 40. The drive mechanism 40 can drive the connecting rod to push the robotic arm so that the massage head 23 extends or retracts into the housing 10. The transmission relationship between the drive mechanism 40 and the connecting rod can be selectively disconnected. By driving the connecting rod and the robotic arm through the drive mechanism 40, the massage head 23 can extend or retract into the housing 10. In emergency situations such as car collisions, the transmission relationship between the drive mechanism 40 and the connecting rod is disconnected, that is, the drive mechanism 40 no longer constrains the connecting rod, releasing the restriction of the drive mechanism 40 on the massage head 23, thereby realizing the collapse of the massage head 23. This massage device 100 can instantly collapse the massage head 23 in emergency situations such as car collisions, preventing injury to the human body.

[0046] Second Embodiment

[0047] This embodiment provides a massage chair, which includes the massage device 100 of the first embodiment described above, and has the same working principle and technical effect as the massage device 100 of the first embodiment described above.

[0049] This embodiment provides a vehicle that includes the massage chair of the second embodiment described above, and has the same working principle and technical effects as the embodiment. The vehicle is capable of controlling the drive mechanism 40 and the linkage to disconnect upon impact.

[0050] In summary, the embodiments of the present invention provide a massage device 100, a massage chair, and a vehicle, which can raise and lower the massage head 23, and in emergency situations such as a car collision, the massage head 23 can instantly collapse to prevent injury to the human body.

[0051] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention.
