Embodiment

[0023] The massage device 100 according to this embodiment includes a housing 10, a mechanical arm, a link rod, and a drive mechanism 40 (see FIG. 1). The mechanical arm is rotatably connected to the housing 10. A rolling ball 23 is installed at one end of the mechanical arm, and the other end is hinged to the link rod. The link rod is connected so as to transmit to the drive mechanism 40. The drive mechanism 40 can extend or retract the rolling ball 23 with respect to the housing 10 by driving the link rod so as to push the mechanical arm. The drive mechanism 40 is connected so as to selectively transmit to the link rod or disconnect the connection.

[0024] Specifically, the mechanical arm comprises a first mechanical arm 21 and a second mechanical arm 22 that are hinged to each other. The link rod includes a first link rod 31 and a second link rod 32. Massage balls 23 are installed on both the first mechanical arm 21 and the second mechanical arm 22. The first mechanical arm 21 is hinged to the first link rod 31. The second mechanical arm 22 is hinged to the second link rod 32. The drive mechanism 40 comprises a slider 46 that moves toward or away from the first mechanical arm 21. Both the first link rod 31 and the second link rod 32 are connected to the slider 46. Incidentally, the drive mechanism 40 drives the slider 46 to slide, which in turn drives the first link rod 31 and the second link rod 32 to move the first mechanical arm 21 and the second mechanical arm 22, thereby raising and lowering the massage balls 23.

[0025] The drive mechanism 40 further comprises a fixed plate 41, a guide rod 42, a shaft sleeve 43, an elastic member 44, a feed screw 47, and a motor 48 (see Figure 3). The slider 46 is connected to link rods 31 and 32 and is slidable relative to the housing 10. The fixed plate 41 is connected to the housing 10 so as to be fixed. The guide rod 42 is connected so as to be fixed to the fixed plate 41. The shaft sleeve 43 is connected so as to be fixed to the slider 46 and is slidable along the guide rod 42. The elastic member 44 is installed between the fixed plate 41 and the shaft sleeve 43. The explosion assembly member 50 comprises a feed screw 47 and a motor 48. The feed screw 47 is connected so as to be fixed to the fixed plate 41 and is parallel to the guide rod 42. The motor 48 is connected so as to be fixed to the slider 46. A stop sleeve 45 is installed on the guide rod 42. The stop sleeve 45 is fixed between the fixed plate 41 and the guide rod 42. The elastic member 44 is installed between the stop sleeve 45 and the shaft sleeve 43. The stop sleeve 45 is in contact with the elastic member 44 to prevent the elastic member 44 from slipping. In this embodiment, a spring can be selected as the elastic member 44. Both ends of the spring are in contact with the stop sleeve 45 and the shaft sleeve 43, respectively.

[0026] The motor 48 is understood to be paired with a feed screw 47, which is fixed to a stationary plate 41. As the motor 48 rotates, it is movable along the feed screw 47, driving the slider 46 to move, which in turn drives the first link rod 31 and the second link rod 32 to move, causing the first mechanical arm 21 and the second mechanical arm 22 to rotate relative to each other, thereby raising and lowering the massage balls 23.

[0027] In this embodiment, to selectively disconnect the transmission relationship between the drive mechanism 40 and the link rod, the lead screw 47 is connected to the fixed plate 41 via an explosion assembly member 50. The explosion assembly member 50 can be selectively disconnected.

[0028] In this case, as shown in Figure 5, specifically, the explosive assembly member 50 comprises a detonator 51, a bolt head 52, a screw rod 55, and a nut. The detonator 51, bolt head 52, screw rod 55, and feed screw 47 are connected in sequence. The bolt head 52 and nut are located on both sides of the fixing plate, respectively. Explosives 53 are placed inside the screw rod 55 located between the bolt head 52 and the nut. The detonator 51 can detonate the explosives 53 in such a way as to detach the screw rod 55.

[0029] In this embodiment, the screw rod 55 may be provided with a notch 54 at the location where the gunpowder 53 is installed. The notch 54 makes it easier to detach the screw rod 55 and at the same time ensures that the position from which the screw rod 55 is detached is fixed.

[0030] It is understood that when the motor 48 moves to the left, the slider 46 is driven to lift the massage balls 23. At this time, the shaft sleeve 43, which is connected to the slider 46 so as to be fixed in place, slides to the left on the guide rod 42, and the elastic member 44 is compressed. In the event of an emergency such as a collision with the vehicle, the screw rod 55 is disconnected, separating the feed screw 47 and the fixing plate 41, and releasing the restriction between the release feed screw 47 and the motor 48 and the fixing plate 41. The elastic member 44 recoils, sliding the shaft sleeve 43 to the right on the guide rod 42, and the slider 46, which is connected to the shaft sleeve 43 so as to be fixed in place, slides to the right, instantly crushing the massage balls 23.

[0031] In other embodiments, the explosive assembly member 50 may be located at the locations of the first link rod 31 and the second link rod 32, and when a vehicle collides with it, it explodes to detach the first link rod 31 and the second link rod 32. This releases the restrictions on the first mechanical arm 21 and the second mechanical arm 22. At this time, since there is no force acting to maintain the protruding state of the massage balls 23, they can be crushed to prevent injury to the human body.

[0032] The operating principle and process of the massage device 100 according to this embodiment are described below. Referring to Figures 1 to 4, the slider 46 is driven by the motor 48 and moves to the left along the feed screw 47 in accordance with the motor 48, driving the first link rod 31 to rotate and push the first mechanical arm 21 clockwise, and driving the second link rod 32 to rotate and push the second mechanical arm 22 counterclockwise, thereby changing the massage balls 23 from the retracted state in Figure 1 to the protruding state in Figure 2. When retracting the massage balls 23, the slider 46 is driven by the motor 48 and moves to the right along the feed screw in accordance with the motor 48, driving the first link rod 31 to pull the first mechanical arm 21 to rotate counterclockwise, and driving the second link rod 32 to pull the second mechanical arm 22 to rotate like a transient needle, thereby changing the massage balls 23 from the protruding state in Figure 2 to the retracted state in Figure 1.

[0033] When the massage balls 23 protrude and an emergency occurs, the elastic member 44 is compressed (see Figure 4). The detonator 51 detonates the gunpowder 53 and disconnects the screw rod 55, separating the feed screw 47 from the fixed plate 41 and releasing the restriction between the feed screw 47 and the motor 48 from the fixed plate 41. The elastic member 44 recoils, causing the shaft sleeve 43 to slide to the right on the guide rod 42, and the slider 46, which is connected to the shaft sleeve 43 so as to be fixed to it, to slide to the right. The slider 46 drives the massage balls 23 to contract downward, instantly crushing the massage balls 23.

[0034] The beneficial effects of the massage device 100 according to this embodiment are as follows: The massage device 100 according to this embodiment comprises a housing 10, a mechanical arm, a link rod, and a drive mechanism 40. The mechanical arm is rotatably connected to the housing 10. A massage ball 23 is installed at one end of the mechanical arm, and the other end is hinged to the link rod. The link rod is connected to the drive mechanism 40 to transmit power. The drive mechanism 40 can extend or retract the massage ball 23 into the housing 10 by driving the link rod to push the mechanical arm. The transmission relationship between the drive mechanism 40 and the link rod can be selectively disconnected. By driving the link rod and the mechanical arm to move using the drive mechanism 40, the massage ball 23 can be extended or retracted into the housing 10. In the event of an emergency such as a collision with a vehicle, disconnecting the transmission relationship between the drive mechanism 40 and the link rod releases the drive mechanism 40 from constraining the link rod, releasing the drive mechanism 40's restriction on the massage ball 23, and causing the massage ball 23 to retract. This massage device 100 prevents injury to the human body by instantly crushing the massage balls 23 in the event of an emergency such as a collision with a vehicle. [Examples]

[0036] The vehicle according to this embodiment is equipped with the massage chair according to the second embodiment described above, and has the same operating principle and technical effects as the embodiment. The vehicle is controlled to disconnect the drive mechanism 40 from the link rod when it is hit.

[0037] In summary, the massage device 100, massage chair, and vehicle according to the embodiment of the present invention raise and lower the massage balls 23, and in the event of an emergency such as a collision with the vehicle, the massage balls 23 are instantly crushed to prevent injury to the human body.
