Example

[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 power 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 selectively connected to transmit power to the link rod or disconnect the connection.

[0024] Specifically, the mechanical arm includes 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. Rolling 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 includes a slider 46, and the slider 46 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, by driving the drive mechanism 40 to slide the slider 46, the first link rod 31 and the second link rod 32 drive the first mechanical arm 21 and the second mechanical arm 22 to move, thereby raising and lowering the rolling ball 23.

[0025] The drive mechanism 40 further includes 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 FIG. 3). The slider 46 is connected to the link rods 31 and 32 and is slidable with respect to the housing 10. The fixed plate 41 is connected to be fixed to the housing 10. The guide rod 42 is connected to be fixed to the fixed plate 41. The shaft sleeve 43 is connected 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 explosive assembly member 50 includes a feed screw 47 and a motor 48. The feed screw 47 is connected to be fixed to the fixed plate 41 and is parallel to the guide rod 42. The motor 48 is connected 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 abuts against the elastic member 44 to prevent the slip of the elastic member 44. In this embodiment, a spring can be selected as the elastic member 44. Both ends of the spring are respectively abutted against the stop sleeve 45 and the shaft sleeve 43.

[0026] It is understood that the motor 48 is combined with the feed screw 47 and the feed screw 47 is fixed to the fixed plate 41. When the motor 48 rotates, since the motor 48 is movable along the feed screw 47, it drives the slider 46 to move, drives the slider 46 to move the first link rod 31 and the second link rod 32, relatively rotates the first robotic arm 21 and the second robotic arm 22, and raises and lowers the rice husk 23.

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

[0028] In this case, as shown in FIG. 5, specifically, the explosive assembly member 50 includes a detonator 51, a bolt head 52, a screw rod 55, and a nut. The detonator 51, the bolt head 52, the screw rod 55, and the feed screw 47 are sequentially connected. The bolt head 52 and the nut are respectively located on both sides of the fixed plate. Gunpowder 53 is installed in the screw rod 55 between the bolt head 52 and the nut. The detonator 51 can detonate the gunpowder 53 so as to disconnect the screw rod 55.

[0029] In this embodiment, the screw rod 55 can be selectively provided with a notch 54 at the position where the gunpowder 53 is installed. The notch 54 can more easily disconnect the screw rod 55 and at the same time ensure fixing the position where the screw rod 55 is disconnected.

[0030] When the motor 48 moves in the left direction, it is understood that the slider 46 drives to lift the grinding wheel 23. At this time, the shaft sleeve 43 connected to be fixed to the slider 46 slides leftward on the guide rod 42, and the elastic member 44 is in a compressed state. When an emergency such as a vehicle collision occurs, by disconnecting the screw rod 55, the feed screw 47 and the fixed plate 41 are disconnected, and the restriction between the release feed screw 47 and the motor 48 and the fixed plate 41 is released. The elastic member 44 rebounds, slides the shaft sleeve 43 rightward on the guide rod 42, and the slider 46 connected to be fixed to the shaft sleeve 43 slides rightward, thereby instantly crushing the grinding wheel 23.

[0031] In other embodiments, the explosive assembly member 50 may be located at the positions of the first link rod 31 and the second link rod 32, and when the vehicle collides, it explodes to disconnect the first link rod 31 and the second link rod 32. In this way, the restriction on the first robotic arm 21 and the second robotic arm 22 is released. At this time, since there is no acting force for the grinding wheel 23 to maintain the protruding state, it 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 will be described below. Referring to FIGS. 1 to 4 together, the slider 46 is driven by the motor 48, moves leftward along the feed screw 47 according to the motor 48, drives the first link rod 31 to rotate the first mechanical arm 21 clockwise and push it, and drives the second link rod 32 to push the second mechanical arm 22 to rotate counterclockwise, converting the rolling ball 23 from the retracted state in FIG. 1 to the protruding state in FIG. 2. When the rolling ball 23 is retracted, the slider 46 is driven by the motor 48, moves rightward along the feed screw according to the motor 48, drives the first link rod 31 to pull the first mechanical arm 21 to rotate counterclockwise, and drives the second link rod 32 to pull the second mechanical arm 22 to rotate like a transient needle, thereby converting the rolling ball 23 from the protruding state in FIG. 2 to the retracted state in FIG. 1.

[0033] When the position of the rolling ball 23 is in the protruding state and an emergency occurs, the elastic member 44 is in a compressed state (see FIG. 4). The explosive device 51 detonates the gunpowder 53 and disconnects the screw rod 55, thereby disconnecting between the feed screw 47 and the fixed plate 41 and releasing the restriction between the feed screw 47 and the motor 48 and the fixed plate 41. The elastic member 44 rebounds, the shaft sleeve 43 slides rightward on the guide rod 42, the slider 46 connected to be fixed to the shaft sleeve 43 slides rightward, and the slider 46 drives the rolling ball 23 to retract downward, thereby instantly crushing the rolling ball 23.

[0034] The beneficial effects of the massage device 100 according to this embodiment are as follows. The massage device 100 according to the embodiment includes 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 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 to be transmitted 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 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 by the drive mechanism 40, it is possible to extend or retract the rolling ball 23 with respect to the housing 10. When an emergency such as a collision occurs in the vehicle, by disconnecting the transmission relationship between the drive mechanism 40 and the link rod, the drive mechanism 40 no longer restrains the link rod, the limitation of the drive mechanism 40 on the rolling ball 23 is released, and the rolling ball 23 contracts. This massage device 100 prevents injury to the human body by instantaneously crushing the rolling ball 23 when an emergency such as a collision occurs in the vehicle.
