[0035] Embodiment 1

[0036] Please refer to Figures 1 to 4The present embodiment provides a camera push-out rotation structure, including a connection structure 20 for fixing a camera (not shown), a lifting assembly 10 for driving the connection structure 20 to move up and down, and a rotation assembly 30 for driving the connection structure 20 to rotate.

[0037] The lifting assembly 10 includes a screw rod 11, a guide rod 12, a platform 13 and a driver 14. The screw rod 11 and the guide rod 12 are arranged in parallel. The guide rod 12 is provided with at least one screw hole and at least one guide hole. The screw hole is for the screw rod 11 to pass through and is screwed with the screw rod 11. Each guide rod 12 passes through a guide hole. The diameter of the guide hole matches the rod diameter of the guide rod 12. The driver 14 drives the screw rod 11 to rotate and the platform 13 moves along the guide rod 12. In the illustrated structure, there are two guide rods 12 and they are located on both sides of the screw rod 11. The two guide rods 12 jointly limit the radial movement and rotation of the platform 13, which is conducive to reducing the radial force of the screw rod 11 and achieving the effect of protecting the screw rod 11. The diameter of the guide hole matches the rod diameter of the guide rod 12, thereby avoiding the shaking of the platform 13 in the horizontal direction and facilitating the smooth movement of the camera. In other embodiments, a linear bearing may be provided between the guide rod 12 and the carrier 13 to reduce the sliding friction between the guide rod 12 and the carrier 13 .

[0038] The connection structure 20 is used for fixing the camera and is rotatably connected to the platform 13. The rotation axis between the connection structure 20 and the platform 13 is parallel to the guide rod 12. The platform 13 moves up and down, and the connection structure 20 moves up and down accordingly.

[0039] The rotating assembly 30 includes a clockwise rotating shaft 31, a clockwise rotating bevel gear 32, a clockwise rotating spur gear 33, a bevel gear 34 and a clockwise rotating rack 35. The clockwise rotating shaft 31 is rotatably connected to the carrier 13 and is perpendicular to the guide rod 12. The clockwise rotating bevel gear 32 and the clockwise rotating spur gear 33 are both connected to the clockwise rotating shaft 31, and are coaxially arranged and rotate synchronously. The bevel gear 34 is fixedly connected to the connecting structure 20 and its center axis coincides with the rotation axis of the connecting structure 20. The bevel gear 34 is meshed with the clockwise rotating bevel gear 32. The clockwise rotating rack 35 is arranged on the moving path of the clockwise rotating spur gear 33 and can be meshed with the clockwise rotating spur gear 33 to drive the clockwise rotating spur gear 33 to rotate.

[0040] The screw 11 rotates to move the stage 13 up and down. During the upward movement of the stage 13, the clockwise spur gear 33 meshes with the clockwise rack 35 and rotates as the stage 13 rises. The clockwise spur gear 33 rotates to drive the coaxial clockwise bevel gear 32 to rotate, and then the bevel gear 34 meshed with the clockwise bevel gear 32 is connected to the connecting structure 20 to rotate, so that the camera rotates. In other words, the arrangement of the clockwise bevel gear 32 and the clockwise rack 35 converts the lifting torque of the stage 13 into a rotational torque that drives the bevel gear 34 and the connecting structure 20 to rotate.

[0041] During the implementation operation, the driver 14 connects the screw rod 11 and drives the screw rod 11 to rotate forward, the platform 13 is lifted upward by a certain distance to extend the camera, and then the clockwise spur gear 33 abuts the clockwise rack 35, and as the screw rod 11 continues to rotate and the platform 13 continues to be lifted, it is meshed and connected with the clockwise rack 35 and rotates under the meshing of the clockwise rack 35, thereby driving the connection structure 20 and the camera to rotate counterclockwise. The driver 14 drives the screw rod 11 to rotate in the opposite direction, and the camera rotates clockwise and then retracts to its original position. Those skilled in the art can adjust the height of the camera lift by adjusting the distance between the clockwise rack 35 and the starting position of the platform 13, and adjust the angle that the camera can rotate by setting the number of teeth of the clockwise rack 35. In order to realize the forward and rearward shooting functions of the camera, the number of teeth of the clockwise rack 35 can at least enable the camera to rotate 180 degrees. Preferably, the number of teeth of the clockwise rack 35 enables the camera to rotate 360 ​​degrees. Combined with the screw connection design of the screw 11 and the platform 13, the camera can stay at any angle within the range of 360 degrees, and shooting at any angle can be achieved. In this embodiment, the driver 14 is a motor. Those skilled in the art can also replace the driver 14 with other drive structures as long as the screw 11 can be driven to rotate. In the illustrated structure, the driver 14 is connected 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.

[0042] From the above analysis, the camera push-out and rotation structure provided in this embodiment can realize the push-out and rotation of the camera, and through the coordinated design of the structure, the effect of camera push-out and rotation can be achieved with one torque input, the structure is simplified, and the transmission method of gear meshing and threaded connection is adopted to ensure the positioning and relative fixation at any angle, and the controllability is strong.

[0043] In another embodiment of the present application, please refer to Figure 2 and Figure 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 arranged with the forward rotating shaft 31 and is separated on 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 arranged and rotate synchronously. The reverse bevel gear 36 is meshed with the bevel gear 34. The reverse rack 39 is located on the moving path of the reverse spur gear 37 and can be meshed with the reverse spur gear 37 to drive the reverse spur gear 37 to rotate. The meshing position of the reverse rack 39 and the reverse spur gear 37 avoids the meshing position of the forward rack 35 and the forward spur gear 33. Avoidance means that the meshing of the reverse rack 39 and the reverse spur gear 37 and the meshing of the forward rack 35 and the forward spur gear 33 do not occur at the same time. In the illustrated structure, the counter-rotating rack 39 is located above and to the side of the clockwise rack 35 , and the counter-rotating spur gear 37 is engaged with the counter-rotating rack 39 only after the clockwise spur gear 33 is engaged with the clockwise rack 35 .

[0044] During the lifting process of the stage 13, the forward spur gear 33 first meshes with the forward rack 35 to achieve the reverse rotation of the camera. After the forward spur gear 33 and the forward rack 35 are completely meshed, the reverse spur gear 37 meshes with the reverse rack 39 to achieve the forward rotation of the camera. Those skilled in the art can also swap the upper and lower height positions of the forward rack 35 and the reverse rack 39, which is not limited here.

[0045] When the clockwise spur gear 33 and the clockwise rack 35 are meshed, the clockwise spur gear 33 rotates to drive the bevel gear 34 to rotate (clockwise spur gear 33-clockwise rotating shaft 31-clockwise bevel gear 32-bevel gear 34). At this time, the counter-rotating bevel gear 36 also rotates due to the meshing of the counter-rotating bevel gear 36 and the bevel gear 34. It should be noted that at this time, the counter-rotating bevel gear 36 and the clockwise bevel gear 32 have opposite directions of rotation. The counter-rotating bevel gear 36, together with the counter-rotating spur gear 37 and the counter-rotating shaft 38, is in an idling state. When the clockwise spur gear 33 is separated from the clockwise rack 35 and the counterclockwise spur gear 37 is meshed with the counterclockwise rack 39, the counterclockwise spur gear 37 rotates to drive the bevel gear 34 to rotate (counterclockwise spur gear 37-counterclockwise shaft 38-counterclockwise bevel gear 36-bevel gear 34). At this time, the clockwise bevel gear 32 is meshed with the bevel gear 34 to rotate the counterclockwise bevel gear. It should be noted that at this time, the clockwise bevel gear 32 and the counterclockwise bevel gear 36 rotate in opposite directions. The clockwise bevel gear 32, together with the clockwise spur gear 33 and the clockwise shaft 31, is in an idling state.

[0046] In this embodiment, the clockwise bevel gear 32 and the clockwise spur gear 33 are integrally arranged as a double gear. The counter-rotating bevel gear 36 and the counter-rotating spur gear 37 are integrally arranged as a double gear. This arrangement can improve the structural connection tightness and reduce connecting parts such as connecting pins. In addition, it should be noted that the clockwise rotating shaft 31 and the counter-rotating rotating shaft 38 are both movably connected to the carrier 13, or the clockwise bevel gear 32 and the clockwise spur gear 33 are both movably connected to the clockwise rotating shaft 31, and the counter-rotating bevel gear 36 and the counter-rotating spur gear 37 are both movably connected to the counter-rotating shaft 38, so as to realize that the clockwise bevel gear 32, the clockwise spur gear 33, the counter-rotating bevel gear 36 and the counter-rotating spur gear 37 are all fixed relative to the carrier 13 and have the freedom to rotate relative to the carrier 13.

[0047] The arrangement of the reverse spur gear 37, reverse bevel gear 36, reverse rack 39 and reverse shaft 38, on the one hand, enables the bevel gear 34 to mesh with the clockwise bevel gear 32 and the reverse bevel gear 36 at the same time, which is beneficial to improving the rotation stability of the connecting structure 20, and on the other hand, enables the camera to achieve counterclockwise rotation and clockwise rotation.

[0048] In another embodiment of the present application, the length of the reverse rack 39 is twice that of the forward rack 35. Under this design, when the platform 13 moves from bottom to top, the forward spur gear 33 meshes with the forward rack 35 to rotate the camera forward by a specific angle, assuming it is -180°, and then the forward spur gear 33 leaves the forward rack 35 and the reverse spur gear 37 meshes with the reverse rack 39 to rotate the camera. Since the reverse rack 39 is twice the length of the forward rack 35, the camera returns to zero and then continues to rotate to a specific reverse angle of +180°. Those skilled in the art can set the specific length of the rack according to the required rotation angle of the camera, and this is not a sole limitation.

[0049] In another embodiment of the present application, the number of teeth and the module of the clockwise bevel gear 32, the counterclockwise bevel gear 36 and the bevel gear 34 are equal. This arrangement is conducive to improving the tightness of the connection and matching between the clockwise bevel gear 32, the counterclockwise bevel gear 36 and the bevel gear 34, reducing transmission noise and improving transmission accuracy.

[0050] In another embodiment of the present application, the camera ejection and rotation structure further includes a retaining frame 40, the retaining frame 40 has a receiving cavity for receiving the lifting assembly 10 and the rotating assembly 30, and the retaining frame 40 also has a connecting hole for the connecting structure 20 to extend out.

[0051] The two ends of the guide rod 12 are respectively fixed to the upper and lower walls of the accommodating chamber, the two ends of the screw rod 11 can be respectively fixed to the upper and lower walls of the accommodating chamber through the bearings 15, the clockwise rack 35 and the counterclockwise rack 39 are fixed to the walls of the accommodating chamber, the carrier 13 is screwed to the screw rod 11, and the carrier 13 moves in the accommodating chamber. The setting of the retaining frame 40 provides support for the lifting assembly 10 and the rotating assembly 30, so that each structure is compactly arranged and forms a module for easy assembly.

[0052] It should be noted that the holder 40 can be in any shape as long as it can provide fixed support for the lifting assembly 10 and the rotating assembly 30. In the structure shown in the figure, the holder 40 has a rectangular frame formed by upper and lower left and right sides and a bottom plate connected to the rectangular frame. The rectangular frame and the bottom plate are enclosed to form a receiving cavity. The screw 11 and the guide rod 12 are connected to the rectangular frame, and the clockwise rack 35 and the counterclockwise rack 39 are fixed to the bottom plate.

[0053] In another embodiment of the present application, the camera push-out rotation structure further includes a limiter 50 for limiting the upward movement of the platform 13. The upward movement of the platform 13 is limited to ensure that the camera stops pushing out after extending to a specified height.

[0054] The carrier 13 is box-shaped and has a placement cavity for the clockwise rotating shaft 31, the clockwise bevel gear 32, the clockwise spur gear 33, the bevel gear 34, the counter-rotating bevel gear 36, the counter-rotating spur gear 37 and the counter-rotating rotating shaft 38 and an avoidance hole for the connecting structure 20 to extend. The limiter 50 is fixedly connected or slidably connected to the connecting structure 20 and is limited between the accommodating cavity and the carrier 13. In the illustrated structure, the limiter 50 is limited between the upper cavity wall of the accommodating cavity and the upper surface of the carrier 13. The carrier 13 supports the clockwise rotating shaft 31, the counter-rotating rotating shaft 38 and the connecting structure 20, and at the same time provides an assembly space for the clockwise bevel gear 32, the clockwise spur gear 33, the bevel gear 34, the counter-rotating bevel gear 36, the counter-rotating spur gear 37 and the counter-rotating rotating shaft 38. The limiter 50 is sleeved on the connecting structure 20 and is limited between the upper surface of the carrier 13 and the upper cavity wall of the accommodating cavity of the retaining frame 40.

[0055] In one embodiment, the stopper 50 is fixedly connected to the connection structure 20. When the platform 13 and the connection structure 20 are lifted to a certain height, the stopper 50 abuts against the upper cavity wall of the accommodating cavity of the holder 40 to limit the platform 13 from further lifting upward. Those skilled in the art may also fix the stopper 50 on the holder 40, and when the platform 13 and the connection structure 20 are lifted to a certain height, the stopper 50 abuts against the platform 13 to limit the platform 13 from further lifting upward.

[0056] In another embodiment, the limiting member 50 and the connecting structure 20 are slidably connected, and when the platform 13 and the connecting structure 20 rise together, the upper and lower surfaces of the limiting member 50 are respectively abutted by the upper cavity wall of the accommodating cavity and the platform 13 .

[0057] Preferably, the connection structure 20 includes an upper connecting rod 21 and a lower connecting rod 22 which are slidably connected. The upper connecting rod 21 is hollow and provided with a spring 23. The stopper 50 is provided at the lower end of the upper connecting rod 21. The lower connecting rod 22 can move relative to the upper connecting rod 21 to compress the spring 23. When the platform 13 rises, the stopper 50 moves upward with the connection structure 20 until it abuts against the retaining frame 40. Then, as the platform 13 is further lifted, the spring 23 is compressed, and the lower connecting rod 22 is pushed into the upper connecting rod 21 until the upper surface of the platform 13 abuts against the stopper 50 to limit the upward lifting of the platform 13. The provision of the spring 23 can mitigate the impact force of the platform 13 rising, and avoid the vibration of the camera caused by the sudden collision between the platform 13 and the retaining frame 40.

[0058] In the illustrated structure, the upper connecting rod 21 is provided with a guide groove 211 extending up and down and downward to the lower surface of the upper connecting rod 21, and the outer surface of the lower connecting rod 22 is provided with a guide bar 221 cooperating with the guide groove 211. The lower connecting rod 22 is inserted into the upper connecting rod 21 and the guide bar 221 is slidably connected to the guide groove 211. The provision of the guide groove 211 and the guide bar 221 limits the relative rotation of the upper connecting rod 21 and the lower connecting rod 22.

[0059] Preferably, when the forward-rotating spur gear 33 is meshed with the forward-rotating rack 35, the spring 23 is in a compressed state. Specifically, the platform 13 moves upward under the drive of the driver 14, 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 retaining frame 40. At this time, the forward-rotating spur gear 33 abuts against the forward-rotating rack 35. Then, as the platform 13 continues to move upward, the lower connecting rod 22 moves relative to the upper connecting rod 21, the spring 23 is compressed, and at the same time, the forward-rotating rack 35 meshes with the forward-rotating spur gear 33 and rotates. After the meshing of the forward-rotating rack 35 and the forward-rotating spur gear 33 is completed, the platform 13 continues to move upward, the lower connecting rod 22 moves relative to the upper connecting rod 21, the spring 23 is further compressed, and the reverse rack 39 and the reverse spur gear 37 begin to mesh and rotate until the upper surface of the platform 13 abuts against the stopper 50. It can be seen from the above process that when the forward spur gear 33 is meshed with the forward rack 35, the spring 23 is in a compressed state, and when the reverse spur gear 37 is meshed with the reverse rack 39, the spring 23 is also in a compressed state. Under this design, the forward spur gear 33 is subject to the upward driving force of the carrier 13, the downward resistance of the spring 23, and the torque of the forward rack 35. The reverse spur gear 37 is simultaneously subject to the upward driving force of the carrier 13, the downward resistance of the spring 23, and the torque of the reverse rack 39. The addition of the downward resistance of the spring 23 can mitigate the driving force of the carrier 13 to move upward and make the movement more moderate, so as to facilitate the precise control of the rotation angle.
