The lifting assembly 10 comprises a screw rod 11, a guide rod 12, a carrier 13 and a driver 14, wherein the screw rod 11 and the guide rod 12 are arranged in parallel, at least one guide rod 12 is arranged, the carrier 13 is provided with a screw hole and at least one guide hole which are all arranged in a penetrating manner, the screw hole is used for the screw rod 11 to penetrate through and is in threaded connection with the screw rod 11, each guide rod 12 penetrates through one guide hole respectively, the aperture of each guide hole is matched with the rod diameter of the guide rod 12, and the driver 14 drives the screw rod 11 to rotate so that the carrier. In the structure shown in the figure, two guide rods 12 are arranged on two sides of the screw rod 11, and the two guide rods 12 jointly limit the radial movement and rotation of the carrier 13, so that the radial stress of the screw rod 11 is reduced, and the effect of protecting the screw rod 11 is achieved. The aperture of the guide hole is matched with the rod diameter of the guide rod 12, so that the carrier 13 is prevented from shaking in the horizontal direction, and the camera can move stably. In other embodiments, linear bearings may be provided between guide bar 12 and stage 13 to reduce sliding friction between guide bar 12 and stage 13.

The connecting structure 20 is used for fixing the camera and is rotatably connected to the carrier 13, and a rotation axis between the connecting structure 20 and the carrier 13 is parallel to the guide rod 12. The stage 13 moves up and down to move the connection structure 20 up and down.

The rotating assembly 30 comprises a forward rotating shaft 31, a forward bevel gear 32, a forward straight gear 33, a bevel gear 34 and a forward rack 35, the forward rotating shaft 31 is rotatably connected to the carrier 13 and is perpendicular to the guide rod 12, the forward bevel gear 32 and the forward straight gear 33 are both connected to the forward rotating shaft 31 and are coaxially arranged and synchronously rotated, the bevel gear 34 is fixedly connected to the connecting structure 20, the central axis of the bevel gear 34 is overlapped with the rotating axis of the connecting structure 20, the bevel gear 34 is in meshing connection with the forward bevel gear 32, and the forward rack 35 is arranged on the moving path of the forward straight gear 33 and can be in meshing connection with the forward straight gear 33 to drive the forward straight gear 33 to rotate.

Screw 11 rotates to move stage 13 up and down. In the process that the carrier 13 moves upwards, the forward-rotation straight gear 33 is meshed with the forward-rotation rack 35 and rotates along with the rising of the carrier 13, the forward-rotation straight gear 33 rotates to drive the coaxially arranged forward-rotation bevel gear 32 to rotate, and then the bevel gear 34 meshed with the forward-rotation bevel gear 32 is communicated with the connecting structure 20 to rotate, so that the camera rotates. That is, the arrangement of the forward bevel gear 32 and the forward rack 35 translates the lifting torque of the stage 13 into a rotational torque that drives the rotation of bevel gear 34 and connecting structure 20.

In operation, the driver 14 is connected to the screw 11 and drives the screw 11 to rotate forward, the carrier 13 is lifted upward by a certain distance to extend the camera, and then the clockwise rotation spur gear 33 abuts against the clockwise rotation rack 35, and is meshed with the clockwise rotation rack 35 and rotates under the meshing of the clockwise rotation rack 35 along with the continuous rotation of the screw 11 and the continuous lifting of the carrier 13, so as to drive the connecting structure 20 and the camera to rotate counterclockwise.

Those skilled in the art can adjust the height of the camera by adjusting the distance between the forward-rotation rack 35 and the starting position of the carrier 13, and adjust the angle that the camera can rotate by setting the number of teeth of the forward-rotation rack 35. To achieve the forward and backward functions of the camera, the number of teeth of the forward-rotation rack 35 can enable the camera to rotate at least 180 degrees. Preferably, the number of teeth of the clockwise rotation rack 35 enables the camera to rotate 360 degrees, and the camera can stay at any angle within the range of 360 degrees by combining the screw joint design of the screw rod 11 and the carrier 13, so that shooting at any angle is realized. In this embodiment, the driver 14 is a motor. The driver 14 can be replaced by other driving structures by those skilled in the art as long as the screw 11 can be driven to rotate. In the illustrated construction, the actuator 14 is coupled to the screw 11 via a transmission structure and drives the screw 11 to rotate. The transmission structure can be a planetary transmission or a parallel shaft transmission.

In another embodiment of the present application, referring to fig. 2 and 3, the rotating assembly 30 further includes a reverse rotating shaft 38, a reverse bevel gear 36, a reverse spur gear 37 and a reverse rack 39, the reverse rotating shaft 38 is coaxially disposed with the forward rotating shaft 31 and is separated from both sides of the connecting structure 20, the reverse bevel gear 36 and the reverse spur gear 37 are both connected to the reverse rotating shaft 38 and are coaxially disposed and synchronously rotate, the reverse bevel gear 36 is engaged with the bevel gear 34, the reverse rack 39 is located on a moving path of the reverse spur gear 37 and can be engaged with the reverse spur gear 37 to drive the reverse spur gear 37 to rotate, and an engagement position of the reverse rack 39 and the reverse spur gear 37 is different from an engagement position of the forward rack 35 and the forward rack 33. Avoidance means that engagement of the reverse rack 39 with the reverse spur gear 37 does not occur simultaneously with engagement of the forward rack 35 with the forward spur gear 33. In the illustrated structure, the reverse rack 39 is located laterally above the forward rack 35, and the reverse spur gear 37 is engaged with the reverse rack 39 only after the forward spur gear 33 is engaged with the forward rack 35.

In the lifting process of the carrying platform 13, the forward-rotation straight gear 33 is firstly meshed with the forward-rotation rack 35 to realize the reverse rotation of the camera, and after the forward-rotation straight gear 33 is meshed with the forward-rotation rack 35, the reverse-rotation straight gear 37 is meshed with the reverse-rotation rack 39 to realize the forward rotation of the camera. Those skilled in the art can also exchange the vertical height positions of the forward rack 35 and the reverse rack 39, and the present invention is not limited thereto.

The reverse bevel gear 36 is in an idling state together with the reverse spur gear 37 and the reverse rotation shaft 38. When the forward rotation straight gear 33 is separated from the forward rotation rack 35 and the reverse rotation straight gear 37 is meshed with the reverse rotation rack 39, the reverse rotation straight gear 37 rotates to drive the bevel gear 34 to rotate (reverse rotation straight gear 37-reverse rotation shaft 38-reverse rotation bevel gear 36-bevel gear 34), at this time, the reverse rotation bevel gear also rotates because the forward rotation bevel gear 32 is meshed with the bevel gear 34, and it should be noted that, at this time, the rotation directions of the forward rotation bevel gear 32 and the reverse rotation bevel gear 36 are opposite. The forward bevel gear 32 is in an idle state together with the forward spur gear 33 and the forward rotation shaft 31.

In this embodiment, the forward bevel gear 32 and the forward spur gear 33 are integrally provided as a dual gear. The reverse bevel gear 36 and the reverse spur gear 37 are integrally provided, and are dual gears.

In addition, it should be noted that both the forward rotation shaft 31 and the reverse rotation shaft 38 are movably connected to the stage 13, or both the forward rotation bevel gear 32 and the forward rotation spur gear 33 are movably connected to the forward rotation shaft 31, and both the reverse bevel gear 36 and the reverse spur gear 37 are movably connected to the reverse rotation shaft 38, so that the forward rotation bevel gear 32, the forward rotation spur gear 33, the reverse bevel gear 36 and the reverse spur gear 37 are fixed in position relative to the stage 13 and have a degree of freedom of rotation relative to the stage 13.

Due to the arrangement of the reverse straight gear 37, the reverse bevel gear 36, the reverse rack 39 and the reverse rotating shaft 38, on one hand, the bevel gear 34 is meshed with the forward bevel gear 32 and the reverse bevel gear 36 simultaneously, so that the rotation stability of the connecting structure 20 is improved, and on the other hand, the camera can rotate anticlockwise and clockwise.

In another embodiment of the present application, the reverse rack 39 is twice as long as the forward rack 35. Under the design, in the process that the carrying platform 13 moves from bottom to top, the forward-rotation straight gear 33 is meshed with the forward-rotation rack 35 to enable the camera to rotate forward by a specific angle, the angle is assumed to be minus 180 degrees, then the forward-rotation straight gear 33 leaves the forward-rotation rack 35 and the reverse-rotation straight gear 37 is meshed with the reverse-rotation rack 39 to enable the camera to rotate, and the reverse-rotation rack 39 is twice as large as the forward-rotation rack 35, so that the camera continues to rotate to a reverse specific angle which is plus 180 degrees after returning to zero degrees. The specific length of the rack can be set by those skilled in the art according to the rotation angle required by the camera, and is not limited herein.

In another embodiment of the present application, the forward bevel gear 32, reverse bevel gear 36, and bevel gear 34 all have the same number of teeth and module. The arrangement is beneficial to improving the tightness of the connection fit among the forward bevel gear 32, the reverse bevel gear 36 and the bevel gear 34, reducing the transmission noise and improving the transmission precision.

It should be noted that the holder 40 may have any shape as long as it is realized to provide a fixed support for the lifting assembly 10 and the rotating assembly 30. In the structure shown in the figure, the retainer 40 is provided with a rectangular frame formed by enclosing from top to bottom and from left to right and a bottom plate connected with the rectangular frame, the rectangular frame and the bottom plate enclose to form an accommodating cavity, the screw rod 11 and the guide rod 12 are connected with the rectangular frame, and the clockwise rotation rack 35 and the counter-rotation rack 39 are fixed on the bottom plate.

In another embodiment of the present application, the camera head ejecting rotation structure further includes a limiting member 50 for limiting the upward movement of the stage 13. The upward movement of the carrier 13 is limited to ensure that the camera stops pushing out after extending out of a specified height.

The carrying platform 13 is box-shaped and has a placing cavity for the clockwise rotation shaft 31, the clockwise rotation bevel gear 32, the clockwise rotation spur gear 33, the bevel gear 34, the reverse bevel gear 36, the reverse spur gear 37 and the reverse rotation shaft 38 and an avoiding hole for the extension of the connecting structure 20, and the limiting piece 50 is fixedly connected or slidably connected with the connecting structure 20 and is limited between the containing cavity and the carrying platform 13. In the illustrated structure, the position-limiting member 50 is limited between the upper cavity wall of the receiving cavity and the upper surface of the carrier 13. The carrier 13 supports the forward rotation shaft 31, the reverse rotation shaft 38 and the connecting structure 20, while providing an assembly space for the forward rotation bevel gear 32, the forward rotation spur gear 33, the bevel gear 34, the reverse bevel gear 36, the reverse spur gear 37 and the reverse rotation shaft 38. The limiting member 50 is sleeved on the connecting structure 20 and limited between the upper surface of the carrier 13 and the upper cavity wall of the accommodating cavity of the holder 40.

In one embodiment, the position-limiting member 50 is fixedly connected to the connecting structure 20. When the carrier 13 and the connecting structure 20 are lifted to a specific height, the limiting member 50 abuts against the cavity wall of the receiving cavity of the holder 40 to limit the carrier 13 from further lifting upwards. One skilled in the art can also fix the limiting member 50 on the holder 40, and when the carrier 13 and the connecting structure 20 are lifted to a specific height, the limiting member 50 abuts against the carrier 13 to limit the carrier 13 from further lifting upwards.

In another embodiment, the limiting member 50 and the connecting structure 20 are connected in a sliding manner, and when the carrier 13 and the connecting structure 20 are lifted until the upper and lower surfaces of the limiting member 50 are abutted by the upper cavity wall of the accommodating cavity and the carrier 13, respectively.

Preferably, the connecting structure 20 includes an upper link 21 and a lower link 22 slidably connected to each other, the upper link 21 is hollow and provided with a spring 23, the stopper 50 is provided at a lower end portion of the upper link 21, and the lower link 22 is movable relative to the upper link 21 to compress the spring 23. When the carrier 13 is raised, the limiting member 50 moves upward along with the connecting structure 20 to abut against the holder 40, and then as the carrier 13 is further raised, the spring 23 is compressed, and the lower link 22 is pushed into the upper link 21 until the upper surface of the carrier 13 abuts against the limiting member 50 to limit the carrier 13 from being raised upward. The spring 23 is provided to alleviate the impact force of the rising of the stage 13 and to avoid the vibration of the camera caused by the sudden impact between the stage 13 and the holder 40.

In the illustrated structure, the upper link 21 is provided with a guide groove 211 extending vertically and downward to the lower surface of the upper link 21, the outer surface of the lower link 22 is provided with a guide strip 221 matching with the guide groove 211, and the lower link 22 is inserted into the upper link 21 and the guide strip 221 is slidingly connected with the guide groove 211. The guide groove 211 and the guide bar 221 are provided to limit the relative rotation of the upper link 21 and the lower link 22.

Preferably, the spring 23 is in a compressed state when the clockwise spur gear 33 is engaged with the clockwise rack 35. Specifically, the stage 13 is driven by the actuator 14 to move upward, and the stopper 50 moves upward together with the connecting structure 20 until the upper surface of the stopper 50 abuts against the upper cavity wall of the holder 40. At this time, the clockwise spur gear 33 abuts against the clockwise rack 35. Then, as the upward movement of the stage 13 continues, the lower link 22 moves relative to the upper link 21, the spring 23 is compressed, and the clockwise rack 35 rotates while meshing with the clockwise spur gear 33. After the forward rack 35 and the forward spur gear 33 are engaged, the carrier 13 continues to move upward, the lower link 22 moves relative to the upper link 21, the spring 23 is further compressed, and the reverse rack 39 and the reverse spur gear 37 start to be engaged and rotated until the upper surface of the carrier 13 abuts against the stopper 50. As can be seen from the above process, when the forward-rotation spur gear 33 is engaged with the forward-rotation rack 35, the spring 23 is in a compressed state, and when the reverse-rotation spur gear 37 is engaged with the reverse-rotation rack 39, the spring 23 is also in a compressed state. With this design, the forward-rotation spur gear 33 receives the upward driving force of the stage 13, the downward resistance of the spring 23, and the torque of the forward-rotation rack 35. The reverse spur gear 37 receives the upward driving force of the stage 13, the downward resistance of the spring 23, and the torque of the reverse rack 39 at the same time. The addition of the downward resistance of the spring 23 can moderate the driving force of the upward movement of the stage 13, so that the movement is more moderate, and the accurate control of the rotation angle is facilitated.
