The first driving device is installed on the base 1, the first driving device provides power for the movement of the first mounting frame 2, and the first linear motion device provides a guiding effect for the movement of the first mounting frame 2. The first linear motion device has various specific embodiments: in a first specific embodiment, the first linear motion device includes a first sliding groove and a first pulley, the first sliding groove is installed on the base 1, the first pulley is installed on the first mounting frame 2, and the first sliding groove is in rolling fit with the first pulley. In a second specific embodiment, the first linear motion device includes a first slide rail 10 and a first slide block 11, the first slide rail 10 is installed on the base 1, the first slide block 11 is installed on the first mounting frame 2, and the first slide rail 10 and the first slide block 11 are in sliding fit. According to the two specific embodiments, the guiding effect of the first linear motion device on the motion of the first mounting frame 2 can be realized. First wedge platform 4 and second wedge platform 7 are all installed on first mounting bracket 2 along the direction of height, and first cam 5 is installed on first rotating frame 3 through first mount pad 6, and second cam 8 is installed on first rotating frame 3 through second mount pad 9. The first mounting seat 6 provides rotational support for the first cam 5 and the second mounting seat 9 provides rotational support for the second cam 8. First mount pad 6 and second mount pad 9 all can include the roof, and the one end of roof is provided with first curb plate, and the other end is provided with the second curb plate, and first curb plate and second curb plate set up relatively, and roof, first curb plate and second curb plate constitute installation space. The first rotating frame 3 is connected with the base 1 through a first rotating structure, and the first rotating frame 3 rotates relative to the base 1 around a first rotating axis of the first rotating structure. The first wedge-shaped table 4 and the second wedge-shaped table 7 form a first wedge-shaped table group, and the first rotating structure is located on the side of the first wedge-shaped table group in the length direction, can be located on two sides of the first wedge-shaped table group in the length direction, and can also be located on the same side of the first wedge-shaped table group in the length direction. The first wedge-shaped table group can be one, and in this case, the first wedge-shaped table 4 and the second wedge-shaped table 7 can be respectively arranged at two ends of the base 1, and together provide a balance supporting function for the first rotating frame 3. The first wedge set may also be plural, in which case the first wedge 4 and the second wedge 7 are disposed adjacently. A plurality of first wedge platform group evenly sets up on base 1, and a plurality of first wedge platform group provides balanced supporting role for first revolving rack 3 jointly. The first driving device drives the first mounting frame 2 to do linear reciprocating motion under the coordination of the first linear motion device, and drives the first cam 5 to roll on the inclined plane of the first wedge-shaped table 4 to form a first rolling track; the second cam 8 rolls on the slope of the second wedge table 7, forming a second rolling track. The first rolling track and the second rolling track are respectively vertical to the first rotation axis. Because the slope of the inclined plane of the first wedge-shaped table 4 is opposite to the slope of the inclined plane of the second wedge-shaped table 7, the lower end of the inclined plane of the first wedge-shaped table 4 is arranged opposite to the lower end of the inclined plane of the second wedge-shaped table 7. Therefore, when the first driving device drives the first mounting frame 2 to move towards the lower end direction of the inclined surface of the second wedge-shaped table 7, the first cam 5 rolls from the lower end to the top end of the inclined surface of the first wedge-shaped table 4, and the second cam 8 rolls from the top end to the lower end of the inclined surface of the second wedge-shaped table 7; when the first driving device drives the first mounting frame 2 to move towards the lower end direction of the inclined surface of the first wedge-shaped table 4, the first cam 5 rolls from the top end of the inclined surface of the first wedge-shaped table 4 to the lower end, and the second cam 8 rolls from the lower end to the top end of the inclined surface of the second wedge-shaped table 7. For example: in specific implementation, the passenger door of the automobile is arranged on the first rotating frame 3, and the first driving device drives the first mounting frame 2 to do linear motion towards the lower end direction of the inclined surface of the first wedge-shaped table 4. When the first cam 5 rolls towards the lower end of the inclined surface of the first wedge-shaped table 4 and the second cam 8 rolls towards the top end of the inclined surface of the second wedge-shaped table 7, the first rotating frame 3 is driven to deflect to a proper position towards the lower end of the inclined surface of the first wedge-shaped table 4, and the first driving device stops working. The first cam 5 is arranged on the inclined surface of the first wedge-shaped table 4 and is acted by a force downwards along the inclined surface; the second cam 8 is on the slope of the second wedge 7, and is pulled upwards along the slope, and the positions of the first cam 5 and the second cam 8 reach an equilibrium state. The inclined surface of the second wedge-shaped table 7 has a limiting effect on the downward rolling of the first cam 5, and the first cam 5 stops continuously rolling towards the lower end of the inclined surface of the first wedge-shaped table 4. The fixation of the position when the first cam 5 and the second cam 8 stop rolling, namely self-locking, is realized. The first turning frame 3 is turned about a first turning axis, effecting a deflection of the first turning frame 3 and the passenger door of the car relative to the position of the base 1.

The second mounting bracket 20 is mounted on the first rotating frame 3 through a second linear motion device, and the second driving device is mounted on the first rotating frame 3. The second linear motion device provides a guide for the movement of the second mount 20. The second linear motion device has various specific embodiments: in the first embodiment, the second linear motion device includes a second sliding groove and a second pulley, the second sliding groove is installed on the first rotating frame 3, the second pulley is installed on the second mounting frame 20, and the second sliding groove is in rolling fit with the second pulley. The length of the second sliding slot is perpendicular to the length of the first sliding rail 10. In a second embodiment, the second linear motion device includes a second slide rail 27 and a second slide block 28, the second slide rail 27 is mounted on the first rotating frame 3, the second slide block 28 is mounted on the second mounting frame 20, and the second slide rail 27 is slidably engaged with the second slide block 28. The length of the second slide rail 27 is perpendicular to the length of the first slide rail 10. In the two specific embodiments, the guiding effect of the second linear motion device on the motion of the second mounting frame 20 can be realized, and the motion track of the first mounting frame 2 can be perpendicular to the motion track of the second mounting frame 20. The third wedge table 21 and the fourth wedge table 24 are vertically installed on the second installation frame 20 in the height direction, the third cam 22 is installed on the lower surface of the second rotary frame 19 through the third installation base 23, and the fourth cam 25 is installed on the lower surface of the second rotary frame 19 through the fourth installation base 26. The third mounting 23 provides rotational support for the third cam 22 and the fourth mounting 26 provides rotational support for the fourth cam 25. The third and fourth mounting seats 23 and 26 may each include a first fixing plate, a second fixing plate is disposed at one side of the first fixing plate, and the first and second fixing plates are disposed opposite to each other and have a rotation space. The second rotation structure has a second rotation axis, and the first rotation frame 3 and the second rotation frame 19 are connected through the second rotation structure. The third wedge-shaped table 21 and the fourth wedge-shaped table 24 form a second wedge-shaped table group, and the second rotating structure is located on the side of the second wedge-shaped table group in the length direction, and can be on the same side of the second wedge-shaped table group in the length direction or on two sides of the second wedge-shaped table group in the length direction. The second driving device drives the second mounting rack 20 to do linear reciprocating motion, and drives the third cam 22 to roll on the inclined plane of the third wedge-shaped table 21 to form a third rolling track; the fourth cam 25 rolls on the slope of the fourth wedge 24 to form a fourth rolling locus. The third rolling track and the fourth rolling track are respectively vertical to the second rotation axis. Because the slope of the inclined plane of the third wedge-shaped table 21 is opposite to the slope of the inclined plane of the fourth wedge-shaped table 24, the lower end of the inclined plane of the third wedge-shaped table 21 is arranged opposite to the lower end of the inclined plane of the fourth wedge-shaped table 24. Therefore, when the third cam 22 rolls from the top end to the bottom end of the inclined surface of the third wedge 21, the fourth cam 25 rolls from the bottom end to the top end of the inclined surface of the fourth wedge 24; when the third cam 22 rolls from the lower end to the upper end of the inclined surface of the third wedge 21, the fourth cam 25 rolls from the upper end to the lower end of the inclined surface of the fourth wedge 24. For example: in specific implementation, the passenger door of the automobile is installed on the second rotating frame 19, when the second driving device drives the second installation frame 20 to make linear motion towards the lower end direction of the inclined surface of the third wedge-shaped table 21, the third cam 22 rolls from the top end of the inclined surface of the third wedge-shaped table 21 to the lower end, the fourth cam 25 rolls from the bottom end of the inclined surface of the fourth wedge-shaped table 24 to the top end, and when the second rotating frame 19 is driven to deflect to a proper position towards the lower end direction of the inclined surface of the third wedge-shaped table 21, the second driving device stops working. The third cam 22 is on the slope of the third wedge 21, and is forced downward along the slope; the fourth cam 25 is on the slope of the fourth wedge 24, and is pulled upward along the slope, and the positions of the third cam 22 and the fourth cam 25 reach an equilibrium state. The inclined surface of the fourth wedge-shaped table 24 has a limiting effect on the downward rolling of the third cam 22, and the third cam 22 stops rolling continuously to the lower end of the inclined surface of the third wedge-shaped table 21. The fixation of the position when the third cam 22 and the fourth cam 25 stop rolling, i.e. self-locking, is achieved. The second turret 19 rotates about a second axis of rotation, effecting a yaw of the second turret 19 and of the passenger door of the vehicle with respect to the position of the first turret 3. The second axis of rotation is collinear with the y-axis of the rectangular coordinate system, and the second rotating frame 19 and the automobile passenger door can rotate around the y-axis.
