[0061] Smart cameras are becoming increasingly popular and can be used for remote meetings, home monitoring, real-time voice chat, etc. In related technologies, smart cameras mainly consist of a base, a camera, and an angle adjustment device. However, when the angle adjustment device adjusts the rotation of the camera, it usually requires a driving mechanism to rotate forward or backward to achieve the angle adjustment of the camera, that is, the driving mechanism needs to switch the rotation direction in real time, which affects the service life of the driving mechanism and results in relatively high requirements for the performance of the driving mechanism, causing the cost to increase.

[0062] Based on the above concepts and problems, the present invention proposes a camera adjustment system 100. It can be understood that the camera adjustment system 100 can be an intelligent device such as a camera device, an electronic monitoring device, or a video and voice device, which is not limited herein.

[0063] Please refer to Figures 1 to 10 As shown, in an embodiment of the present invention, the camera adjustment system 100 includes a base 1, a camera assembly 2, a driving mechanism 3, and a controller. The base 1 is provided with an installation cavity 11 and a rotation groove 14 communicating with the installation cavity 11. The camera assembly 2 is provided with a rotating shaft 211, and the rotating shaft 211 is rotatably connected in the rotation groove 14. The rotating shaft 211 is provided with a sliding cavity 212 communicating with the installation cavity 11. The driving mechanism 3 includes a lifting assembly 31, a driving member, and a transmission member 32. The lifting assembly 31 is connected to the transmission member 32 or the driving member. One end of the transmission member 32 is slidably disposed in the sliding cavity 212. The transmission member 32 is provided with a transmission tooth 327, and the driving member is provided with a driving gear 33. The driving gear 33 has opposite first meshing positions 334 and second meshing positions 335. The controller is electrically connected to the camera assembly 2, the lifting assembly 31, and the driving member. The controller is configured to control the driving member to drive the driving gear 33 to rotate, and control the lifting assembly 31 to drive the transmission member 32 to move along the sliding cavity 212.

[0064] In this embodiment, the lifting assembly 31 drives the transmission member 32 or the driving member to move along the sliding cavity 212, so that the transmission tooth 327 meshes with the driving gear 33 at the first meshing position 334 or the second meshing position 335, so that the driving gear 33 drives the transmission member 32 and the camera assembly 2 to rotate forward or backward.

[0065] It can be understood that the controller can be a control device, a control circuit, or a circuit board integrated with a control program, etc., which is not limited herein. The controller can be integrally disposed on the base 1 or the camera assembly 2 of the camera adjustment system 100. Of course, the controller can also be separately disposed from the camera adjustment system 100, so that the controller can be a separate remote control device or integrated on the user's mobile device. At this time, the controller is connected to the camera adjustment system 100 by wire or wirelessly, such as Bluetooth connection, wifi connection, infrared connection, etc., which is not limited herein.

[0066] In this embodiment, the base 1 provides an installation or rotation foundation for the imaging component 2, the driving mechanism 3, and the controller. The base 1 can be a structure such as a housing, a box, a case, a seat body, or a bracket having an installation cavity 11. In this embodiment, the installation cavity 11 of the base 1 is used to install and protect structures such as the driving mechanism 3 and the controller. In order to enable the imaging component 2 to rotate or turn relative to the base 1, the base 1 is further provided with a rotation hole 12 communicating with the installation cavity 11, and the outer shell 21 is movably connected to the base 1 to facilitate the rotation of the outer shell 21 relative to the base 1.

[0067] It can be understood that the base 1 is further provided with a rotation groove 14, and the rotation hole 12 is opened on the bottom wall of the rotation groove 14. By providing the rotation groove 14 on the base 1 and a rotating shaft 211 protruding from the imaging component 2, it is convenient for the imaging component 2 to use the rotating shaft 211 to achieve a rotating connection with the base 1 through the rotation groove 14.

[0068] It should be noted that in order to prevent the imaging component 2 from moving along the axial direction of the transmission member 32 when the lifting component 31 drives the transmission member 32 to move along its axial direction, a limiting boss is provided on one of the groove wall of the rotation groove 14 and the outer wall of the rotating shaft 211, and a limiting groove is provided on the other. The limiting boss is slidably limited in the limiting groove, and the limiting boss or the limiting groove extends along the circumferential direction of the rotation groove 14 and is perpendicular to the axial direction of the rotating shaft 211. Thus, the limiting boss and the limiting groove are used in cooperation to limit the rotating shaft 211 of the imaging component 2 in the axial direction and rotate in the circumferential direction.

[0069] In order to facilitate the disassembly and assembly of components such as the imaging component 2 and the driving mechanism 3, in this embodiment, the base 1 is provided in a split structure, that is, the base 1 includes a first bottom shell and a second bottom shell, and the first bottom shell and the second bottom shell enclose to form the installation cavity 11 and the rotation hole 12 communicating with the installation cavity 11. Optionally, the first bottom shell and the second bottom shell are fixed together by ultrasonic heat melting or snap connection, which is not limited herein.

[0070] In this embodiment, by providing a sliding cavity 212 on the rotating shaft 211, when the imaging component 2 is rotatably connected to the base 1, the sliding cavity 212 corresponds to and communicates with the rotation hole 12. In this way, one end of the transmission member 32 of the driving mechanism 3 can pass through the rotation hole 12 and slide through the sliding cavity 212. It can be understood that the transmission member 32 of the driving mechanism 3 can drive the imaging component 2 to rotate relative to the base 1, that is, the imaging component 2 rotates around the axial direction of the transmission member 32 or the axial direction of the rotation hole 12.

[0071] Optionally, the imaging assembly 2 rotates 360° around the axial direction of the transmission member 32 or the axial direction of the rotation hole 12. In this embodiment, the imaging assembly 2 can rotate forward or backward relative to the base 1. Optionally, the forward rotation angle of the imaging assembly 2 relative to the base 1 is 0° to 180°, and the backward rotation angle of the imaging assembly 2 relative to the base 1 is 0° to 180°. In this way, the imaging adjustment system 100 can achieve 360° rotation to capture dynamic users in real time.

[0072] In this embodiment, the imaging assembly 2 has a first state of rotating forward relative to the base 1 and a second state of rotating backward relative to the base 1. By providing the lifting assembly 31, the driving member and the transmission member 32, the lifting assembly 31 is arranged in the installation cavity 11 and connected to the transmission member 32 or the driving member. A driving gear 33 is provided at the output end of the driving member. The driving gear 33 has opposite first meshing positions 334 and second meshing positions 335, and a transmission tooth 327 is provided on the transmission member 32. The lifting assembly 31 is used to push the transmission member 32 or the driving member to move along the axial direction of the transmission member 32, so that the driving gear 33 meshes with the transmission tooth 327 at the first meshing position 334 or the second meshing position 335. That is, in the first state, the transmission tooth 327 meshes with the driving gear 33 at the first meshing position 334; in the second state, the transmission tooth 327 meshes with the driving gear 33 at the second meshing position 335. Thus, when the lifting assembly 31 pushes the transmission member 32 to move along the sliding cavity 212 or the driving member to move along the axial direction of the transmission member 32, the transmission tooth 327 of the transmission member 32 meshes with the driving gear 33 at the first meshing position 334 or the second meshing position 335 to realize the forward rotation or backward rotation of the imaging assembly 2.

[0073] It can be understood that the rotation direction of the driving member driving the driving gear 33 is as Figure 9 and Figure 10 shown. In the first state, the transmission tooth 327 meshes with the driving gear 33 at the first meshing position 334. At this time, the transmission tooth 327 drives the transmission member 32 to rotate counterclockwise, realizing the forward rotation of the imaging assembly 2 relative to the base 1, as Figure 9 shown; in the second state, the transmission tooth 327 meshes with the driving gear 33 at the second meshing position 335. At this time, the transmission tooth 327 drives the transmission member 32 to rotate clockwise, realizing the backward rotation of the housing 21 relative to the base 1, as Figure 10 shown.

[0074] In this embodiment, the lifting assembly 31 is connected to the transmission member 32. The lifting assembly 31 pushes the transmission member 32 to move along the sliding cavity 212, so that the transmission teeth 327 are engaged with different rotational positions of the driving gear 33 (i.e., the first engagement position 334 or the second engagement position 335), thereby realizing the forward or reverse rotation of the imaging assembly 2 relative to the base 1 without changing the rotation direction of the driving gear 33. In this way, the performance requirements of the driving member can be effectively reduced, and the cost of the imaging adjustment system 100 can be effectively saved.

[0075] It should be noted that the lifting assembly 31 pushes the transmission member 32 to reciprocate along the sliding cavity 212. The lifting assembly 31 can be a pushing cylinder, a telescopic rod, or other structures capable of realizing reciprocating movement, which is not limited herein. It can be understood that the structure of the lifting assembly 31 is much lower in terms of the precision, cost, and structure of the driving member, and is easy to implement and install. Compared with the traditional method of switching the rotation direction in real time through the driving mechanism, the performance requirements of the driving member are effectively reduced.

[0076] The imaging adjustment system 100 of the present invention is provided with an installation cavity 11 and a rotating groove 14 communicating with the installation cavity 11 on the base 1, so as to install and protect the driving mechanism 3, the controller, and other components by using the installation cavity 11. A rotating shaft 211 is provided on the imaging assembly 2, so that the imaging assembly 2 is rotatably connected to the rotating groove 14 through the rotating shaft 211, thereby realizing the rotational connection between the imaging assembly 2 and the bottom shell 1. At the same time, a sliding cavity 212 communicating with the installation cavity 11 is provided on the rotating shaft 211, so as to facilitate one end of the transmission member 32 of the driving mechanism 3 to slide through the sliding cavity 212. A transmission tooth 327 is provided on the transmission member 32, a driving gear 33 is provided at the output end of the driving member, and opposite first engagement position 334 and second engagement position 335 are formed on the driving gear 33. Thus, the controller is used to control the lifting assembly 31 to push the transmission member 32 or the driving member to move along the axial direction of the transmission member 32, so that the transmission teeth 327 are engaged with the driving gear 33 at the first engagement position 334 or the second engagement position 335, and the controller is used to control the driving member to drive the driving gear 33 to drive the transmission member 32 and the imaging assembly 2 to rotate forward or backward, that is, without changing the rotation direction of the driving member driving the driving gear 33, the transmission teeth 327 are engaged with the driving gear 33 at the first engagement position 334 or the second engagement position 335, thereby realizing the forward or reverse rotation of the imaging assembly 2 relative to the base 1. In this way, the performance requirements of the driving member can be effectively reduced.

[0077] In one embodiment, the imaging assembly 2 includes a housing 21 and a camera 22. The housing 21 is provided with a rotating shaft 211, and the camera 22 is disposed in the housing 21 and is electrically connected to the controller.

[0078] In this embodiment, as Figures 1 to 3 shown, the housing 21 provides an installation basis for structures such as the camera 22, video and voice module, and control circuit of the camera assembly 2. In order to facilitate the disassembly and assembly of the housing 21 and structures such as the camera 22, video and voice module, and control circuit of the camera assembly 2, in this embodiment, the housing 21 is provided with a split structure, that is, the housing 21 includes a first housing and a second housing, and the first housing and the second housing enclose to form an installation cavity and a sliding cavity 212. Optionally, the first housing and the second housing are fixed together by ultrasonic hot melting or buckles, which is not limited herein.

[0079] It can be understood that a rotating shaft 211 is provided on the side of the housing 21 facing the base 1, the rotating shaft 211 extends into the rotating groove 14, and the sliding cavity 212 of the rotating shaft 211 is correspondingly communicated with the installation cavity 11 through the rotating hole 12. The camera 22 can be installed inside the housing 21, and through holes are provided on the housing 21 to facilitate the camera 22 to shoot or detect the external environment. Of course, an installation groove communicating with the inside of the housing 21 can also be provided on the housing 21, and the camera 22 is accommodated and limited in the installation groove, which is not limited herein.

[0080] The camera adjustment system 100 of the present invention installs and protects components such as the driving mechanism 3 and the controller by providing the installation cavity 11 and the rotating hole 12 communicating with the installation cavity 11 on the base 1. By providing the sliding cavity 212 on the rotating shaft 211 of the housing 21 and rotatably connecting the housing 21 to the rotating groove 14 of the base 1 through the rotating shaft 211, the sliding cavity 212 is correspondingly communicated with the rotating hole 12, so that one end of the transmission member 32 of the driving mechanism 3 is connected to the lifting assembly 31, and the other end of the transmission member 32 passes through the rotating hole 12 and slidably penetrates through the sliding cavity 212. Thus, the lifting assembly 31 is used to push the transmission member 32 to move along the axial direction of the transmission member 32 to slide in the sliding cavity 12. By providing spaced transmission teeth 327 on the transmission member 32 and a driving gear 33 at the output end of the driving member, the driving gear 33 is engaged with the transmission teeth 327, so that the housing 21 has a first state of rotating forward relative to the base 1 and a second state of rotating backward relative to the base. In the first state, the transmission teeth 327 are engaged with the driving gear 33 at the first engagement position 334; in the second state, the transmission teeth 327 are engaged with the driving gear 33 at the second engagement position 335, that is, without changing the transmission direction of the driving gear 33, the transmission teeth 327 are respectively engaged with the driving gear 33, so as to realize the forward rotation or reverse rotation of the housing 21 relative to the base 1, and thus the performance requirements of the driving member can be effectively reduced.

[0081] In one embodiment, as Figure 1As shown, the camera module 2 further includes a voice module 23 provided in the housing 21. The voice module 23 includes a voice receiving module and / or a voice output module, and the voice receiving module and / or the voice output module is electrically connected to the controller.

[0082] It can be understood that by providing the voice module 23, external voice information can be received through the voice module 23, or voice information can be output to the outside, etc., which is not limited here. In this embodiment, the voice module 23 can be at least one of a microphone and a speaker, which is not limited here.

[0083] In one embodiment, the driving gear 33 includes a rotating disk 331 connected to the output end of the driving member and a plurality of teeth 332. The rotating disk 331 is opposite to and spaced from the transmission member 32. The plurality of teeth 332 protrude from the peripheral edge of the rotating disk 331 facing the transmission member 32 and extend towards the transmission member 32. Opposite first meshing positions 334 and second meshing positions 335 are formed on the peripheral edge of the rotating disk 331. The connection line of the first meshing position 334 and the second meshing position 335 passes through the rotation center of the rotating disk 331 and is parallel to the axial direction of the transmission member 32.

[0084] In this embodiment, as Figure 2 、 Figure 3 、 Figures 8 to 10 shown, by opposing the rotating disk 331 of the driving gear 33 to the transmission member 32 and making the plane where the rotating disk 331 is located parallel to the axial direction of the transmission member 32, that is, the driving gear 33 is vertically arranged, so that the plurality of teeth 332 of the rotating disk 331 are arranged along the peripheral edge of the rotating disk 331 and extend towards the transmission member 32.

[0085] It can be understood that opposite first meshing positions 334 and second meshing positions 335 are provided on the peripheral edge of the rotating disk 331, and the connection line of the first meshing position 334 and the second meshing position 335 passes through the rotation center of the rotating disk 331 and is parallel to the axial direction of the transmission member 32. In this way, it can be ensured that the teeth 332 at the first meshing position 334 or the second meshing position 335 of the rotating disk 331 mesh with the transmission teeth 327. Thus, when the driving member drives the rotating disk 331 of the driving gear 33 to drive the plurality of teeth 332 to rotate, when the transmission teeth 327 mesh with the teeth 332 of the driving gear 33, the transmission member 32 and the housing 21 are driven to rotate.

[0086] It should be noted that the first meshing position 334 and the second meshing position 335 are spaced along the axial direction of the transmission member 32 on the rotating disk 331 and are located in the regions corresponding to two fixed positions in the physical space when the rotating disk 331 rotates, rather than two fixed and unchanging regions on the rotating disk 331.

[0087] In this embodiment, the moving directions of the teeth 332 at the first engagement position 334 of the rotating disk 331 and the teeth 332 at the second engagement position 335 are opposite, that is, as Figure 9 and Figure 10 shown, the moving direction of the teeth 332 at the first engagement position 334 is towards the inside, and the moving direction of the teeth 332 at the second engagement position 335 is towards the outside. In this way, when the transmission gear 327 meshes with the teeth 332 at the first engagement position 334, the rotation directions of the transmission member 32 and the housing 21 are opposite to those when the transmission gear 327 meshes with the teeth 332 at the second engagement position 335, thereby realizing the forward and reverse rotation switching of the housing 21.

[0088] It can be understood that the teeth 332 at the first engagement position 334 and the teeth 332 at the second engagement position 335 are located on the same diameter direction of the rotating disk 331, that is, the connection line between the first engagement position 334 and the second engagement position 335 is parallel to the axial direction of the transmission member 32.

[0089] In one embodiment, the driving gear 33 further includes a connecting shaft 333. The connecting shaft 333 protrudes from the side of the rotating disk 331 facing away from the teeth 332. A connecting hole 13 corresponding to the connecting shaft 333 is provided on the cavity wall of the installation cavity 11. The connecting shaft 333 is rotatably connected in the connecting hole 13 and is connected to the output end of the driving member.

[0090] In this embodiment, as Figure 2 、 Figure 3 、 Figure 4 、 Figures 8 to 10 shown, by providing the connecting shaft 333 on the driving gear 33, on the one hand, it is convenient to connect the connecting shaft 333 with the driving member; on the other hand, by providing the connecting hole 13 corresponding to the connecting shaft 333 on the cavity wall of the installation cavity 11, the connecting shaft 333 is rotatably connected in the connecting hole 13, thereby providing a fixed basis for the installation of the driving gear 33. Optionally, the driving member is a driving motor or a rotating motor.

[0091] In one embodiment, the transmission member 32 includes a transmission rod 321 and a first transmission wheel 325 sleeved on the outer wall of the transmission rod 321. One end of the transmission rod 321 is connected to the lifting assembly 31, and the other end of the transmission rod 321 is slidably inserted into the sliding cavity 212. The circumferential edge of the first transmission wheel 325 is provided with transmission teeth 327.

[0092] In this embodiment, as Figure 2 、 Figure 3 、 Figure 7 、 Figure 9 、 Figure 10As shown, the transmission rod 321 of the transmission member 32 can be selected as a rod-shaped or cylindrical structure, and the first transmission wheel 325 can be selected as a gear disc structure, that is, transmission teeth 327 are provided on the periphery of the first transmission wheel 325. It can be understood that by controlling the lifting assembly 31 through the controller to drive the transmission rod 321 to drive the first transmission wheel 325 to reciprocate between the first meshing position 334 and the second meshing position 335, so that the transmission teeth 327 of the first transmission wheel 325 mesh with the driving gear 33 at the first meshing position 334 or the second meshing position 335, and the controller is used to control the driving member to drive the driving gear 33 to rotate in the same direction, so as to realize the forward and reverse rotation switching of the housing 21.

[0093] It can be understood that the transmission teeth 327 are the teeth provided on the periphery of the first transmission wheel 325. The transmission teeth 327 include a plurality of them, and the plurality of transmission teeth 327 are arranged along the circumferential direction of the periphery of the first transmission wheel 325.

[0094] In an embodiment, the transmission member 32 includes a second transmission wheel 326 sleeved on the outer wall of the transmission rod 321. The first transmission wheel 325 and the second transmission wheel 326 are arranged at intervals along the extension direction of the transmission rod 321, and transmission teeth 327 are provided on the periphery of the second transmission wheel 326.

[0095] In this embodiment, as Figure 2 、 Figure 3 、 Figure 4 、 Figures 8 to 10 As shown, the first transmission wheel 325 and the second transmission wheel 326 are arranged at intervals along the extension direction of the transmission rod 321. The second transmission wheel 326 can be selected as a gear disc structure, that is, transmission teeth 327 are provided on the periphery of the second transmission wheel 326. Optionally, in order to control the forward or reverse rotation speed of the housing 21, the diameters of the first transmission wheel 325 and the second transmission wheel 326 are the same.

[0096] It can be understood that the transmission teeth 327 are the teeth provided on the periphery of the second transmission wheel 326. The transmission teeth 327 include a plurality of them, and the plurality of transmission teeth 327 are arranged along the circumferential direction of the periphery of the second transmission wheel 326. Optionally, in order to further accurately control the forward or reverse rotation speed of the housing 21, the number of the transmission teeth 327 of the first transmission wheel 325 is the same as that of the transmission teeth 327 of the second transmission wheel 326. Of course, the size and shape of the transmission teeth 327 of the first transmission wheel 325 are the same as those of the transmission teeth 327 of the second transmission wheel 326.

[0097] To avoid interference between the transmission teeth 327 of the first transmission wheel 325 and the teeth 332 at the first meshing position 334 when the transmission teeth 327 of the first transmission wheel 325 mesh with the teeth 332; or, to avoid interference between the transmission teeth 327 of the second transmission wheel 326 and the driving gear 33 when the transmission teeth 327 of the second transmission wheel 326 mesh with the teeth 332 at the second meshing position 335. In this embodiment, as Figures 9 to 10 shown, the length of the connection line between the first meshing position 334 and the second meshing position 335 is not equal to the distance between the transmission teeth 327.

[0098] Optionally, the length of the connection line between the first meshing position 334 and the second meshing position 335 is greater than the distance between the transmission teeth 327. Of course, the length of the connection line between the first meshing position 334 and the second meshing position 335 can also be less than the distance between the transmission teeth 327.

[0099] It can be understood that the diameter of the rotating disk 331 of the driving gear 33 is greater than the distance between the transmission teeth 327. Of course, in other embodiments, the diameter of the rotating disk 331 of the driving gear 33 is less than the distance between the first transmission wheel 325 and the second transmission wheel 326. That is, the diameter of the rotating disk 331 of the driving gear 33 is not the same as the distance between the first transmission wheel 325 and the second transmission wheel 326.

[0100] It should be noted that when the diameter of the rotating disk 331 of the driving gear 33 is greater than the distance between the first transmission wheel 325 and the second transmission wheel 326, when the transmission teeth 327 of the first transmission wheel 325 mesh with the teeth 332 at the first meshing position 334, the transmission teeth 327 of the second transmission wheel 326 are located in the avoidance groove space formed by enclosing the rotating disk 331 and the teeth 332, and the transmission teeth 327 of the second transmission wheel 326 do not abut or interfere with the rotating disk 331 and the teeth 332. Of course, when the transmission teeth 327 of the second transmission wheel 326 mesh with the teeth 332 at the second meshing position 335, the transmission teeth 327 of the first transmission wheel 325 are located in the avoidance groove space formed by enclosing the rotating disk 331 and the teeth 332, and the transmission teeth 327 of the first transmission wheel 325 do not abut or interfere with the rotating disk 331 and the teeth 332.

The guiding protrusion 213 and the guiding groove 324 both extend along the axial direction of the transmission rod 321, and the guiding protrusion 213 is slidably limited in the guiding groove 324. It can be understood that such a setting can enable the transmission member 32 to slide in the sliding cavity 212 along its axial direction and can also drive the housing 21 to rotate around its axial direction.

[0103] Optionally, the distance from the end of the transmission rod 321 away from the lifting assembly 31 to the second transmission wheel 326 is greater than the length of the sliding cavity 212. In this embodiment, the length of the sliding cavity 212 is greater than the maximum pushing stroke of the lifting assembly 31. Optionally, the sum of the maximum pushing stroke of the lifting assembly 31 and the distance between the first transmission wheel 325 and the second transmission wheel 326 is equal to the diameter of the rotating disk 331.

[0104] In one embodiment, the cavity wall of the installation cavity 11 is further provided with a fixing groove 15 corresponding to the rotation groove 14. The lifting assembly 31 includes a lifting main body 311 and a lifting rod 313. The lifting main body 311 is arranged in the fixing groove 15. A movable cavity 312 is provided on the side of the lifting main body 311 facing away from the fixing groove 15. One end of the lifting rod 313 is movably inserted into the movable cavity 312 and is connected to the lifting main body 311. The other end of the lifting rod 313 is connected to the end of the transmission member 32 away from the sliding cavity 212; wherein, the lifting main body 311 drives the lifting rod 313 to drive the transmission member 32 to move along the axial direction of the transmission member 32.

[0105] In this embodiment, as Figures 2 to 4 , Figure 6 shown, the lifting assembly 31 is a structure or device capable of driving the transmission member 32 to move along its axial direction, such as a driving cylinder, a lifting motor or a telescopic rod structure or other structures or devices capable of driving the transmission member 32 to move along its axial direction, which are not limited herein. It can be understood that, in order to realize the limit and positioning installation of the lifting main body 311, in this embodiment, as Figures 2 to 4 , Figure 6 shown, a fixing groove 15 is provided on the bottom wall of the installation cavity 11 of the bottom shell 1, and part of the lifting main body 311 is received and limited in the fixing groove 15.

[0106] It can be understood that by setting the lifting assembly 31 as the lifting main body 311 and the lifting rod 313, and arranging the lifting main body 311 in the installation cavity 11, the movable cavity 312 is coaxially arranged with the rotation hole 12, so as to realize the sliding of the transmission member 32 along the sliding cavity 212 of the outer shell 21, and at the same time, the transmission member 32 can drive the outer shell 21 to rotate around its axial direction.

[0107] In an embodiment, an installation groove 322 is provided at one end of the transmission member 32 adjacent to the lifting rod 313. One end of the lifting rod 313 away from the lifting main body 311 is disposed in the installation groove 322. One of the groove walls of the installation groove 322 and the lifting rod 313 is provided with a positioning protrusion 323, and the other of the two is provided with a positioning groove 314. The positioning protrusion 323 is received and limited in the positioning groove 314.

[0108] In this embodiment, as Figure 2 , Figure 6 , Figure 9 and Figure 10 shown, by providing the installation groove 322 on the transmission rod 321 of the transmission member 32, the limit installation and fixation are realized by using the installation groove 322 and the lifting rod 313. It can be understood that in order to enable the transmission member 32 to rotate under the drive of the drive gear 33, one end of the lifting rod 313 away from the transmission member 32 movably penetrates through the movable cavity 312. Optionally, the lifting rod 313 is rotatably connected to the cavity wall of the movable cavity 312.

[0109] In order to further limit the installation of the transmission rod 321 of the transmission member 32 and the lifting rod 313, one of the groove walls of the installation groove 322 and the lifting rod 313 is provided with a positioning protrusion 323, and the other of the two is provided with a positioning groove 314. The positioning protrusion 323 is received and limited in the positioning groove 314. It can be understood that the groove wall of the installation groove 322 is provided with a positioning protrusion 323, and the outer wall of the lifting rod 313 is provided with a positioning groove 314; or the groove wall of the installation groove 322 is provided with a positioning groove 314, and the outer wall of the lifting rod 313 is provided with a positioning protrusion 323; or the groove wall of the installation groove 322 is provided with a positioning protrusion 323 and a positioning groove 314, and the outer wall of the lifting rod 313 is provided with a positioning groove 314 and a positioning protrusion 323. At this time, the positioning protrusion 323 of the installation groove 322 corresponds to the positioning groove 314 of the lifting rod 313, and the positioning groove 314 of the installation groove 322 corresponds to the positioning protrusion 323 of the lifting rod 313, which is not limited herein.

[0110] Optionally, the positioning protrusion 323 includes a plurality of positioning protrusions 323 spaced along the peripheral edge of the side wall of the installation groove 322, and the positioning grooves 314 correspond to the positioning protrusions 323 one by one. In this embodiment, the guiding groove 324 extends along the outer wall of the transmission rod 321.

[0111] In an embodiment, as Figures 2 to 4 shown, a rotation hole 12 is formed in the bottom wall of the rotation groove 14. The rotating shaft 211 is rotatably received in the rotation groove 14 and abuts against and is limited by the bottom wall of the rotation groove 14, and the sliding cavity 212 communicates with the installation cavity 11 through the rotation hole 12.

[0112] It can be understood that the rotation hole 12 is formed in the bottom wall of the rotation groove 14. The outer shell 21 is provided with a rotating shaft 211. The rotating shaft 211 is rotatably received in the rotation groove 14 and is in movable contact with the bottom wall of the rotation groove 14. The rotating shaft 211 is provided with a sliding cavity 212. One of the groove wall of the rotation groove 14 and the outer wall of the rotating shaft 211 is provided with a limiting boss, and the other of the two is provided with a limiting groove. The limiting boss is slidably limited in the limiting groove, and the limiting boss or the limiting groove extends along the circumferential direction of the rotation groove 14 and is perpendicular to the axial direction of the rotating shaft 211.

[0113] In this embodiment, by providing a rotation groove 14 in the base 1 and protruding a rotating shaft 211 on the outer shell 21, it is convenient for the outer shell 21 to use the rotating shaft 211 and the rotation groove 14 to realize the rotational connection with the base 1. It can be understood that in order to prevent the outer shell 21 from moving along the axial direction of the transmission member 32 when the lifting assembly 31 drives the transmission member 32 to move along its axial direction, by providing a limiting boss on one of the groove wall of the rotation groove 14 and the outer wall of the rotating shaft 211, and a limiting groove on the other of the two, the limiting boss is slidably limited in the limiting groove, and the limiting boss or the limiting groove extends along the circumferential direction of the rotation groove 14 and is perpendicular to the axial direction of the rotating shaft 211, so as to use the cooperation of the limiting boss and the limiting groove to limit the rotating shaft 211 of the outer shell 21 in the axial direction and rotate in the circumferential direction.

[0114] In one embodiment, the camera adjustment system 100 further includes a displacement detection member disposed in the installation cavity 11. The displacement detection member is electrically connected to the controller and is used to detect the meshing condition of the transmission gear 327 with the driving gear 33 at the first meshing position 334 or the second meshing position 335.

[0115] In this embodiment, the camera adjustment system 100 controls the working states of the lifting assembly 31 and the driving member of the driving mechanism 3 through the controller or the control device. It can be understood that by providing the displacement detection member, the displacement detection member is used to detect the meshing condition of the transmission gear 327 and the driving gear 33, so that the displacement detection member feeds back the detection signal to the controller or the control device, so as to facilitate the controller or the control device of the camera adjustment system 100 to more accurately or precisely control the working states of the lifting assembly 31 and the driving member of the driving mechanism 3.

[0116] The present invention also proposes a control method for the above-mentioned camera adjustment system 100. The control method of the camera adjustment system 100 includes:

[0117] Obtain a control signal. The controller receives the control signal and determines whether the control signal is a forward rotation signal or a reverse rotation signal;

[0118] Control the lifting assembly 31 to drive the transmission member 32 or the driving member to move to the target position according to the forward rotation signal or the reverse rotation signal. The target position is the first engagement position 334 or the second engagement position 335, so that the transmission teeth 327 of the transmission member 32 engage with the driving gear 33 at the first engagement position 334 or the second engagement position 335;

[0119] Control the driving member to drive the driving gear 33 to rotate; so that the driving gear 33 drives the transmission member 32 and the imaging assembly 2 to rotate forward or backward.

[0120] In this embodiment, the specific structure of the imaging adjustment system 100 refers to the foregoing embodiment. Since this method adopts all the technical solutions of all the foregoing embodiments, it at least has all the beneficial effects brought by the technical solutions of the foregoing embodiments, and will not be elaborated herein one by one.

[0121] It can be understood that a control signal is obtained through the camera 22 or the voice module 23 of the imaging adjustment system 100. For example, the azimuth information or the lip movement information of an external person is collected through the camera 22, or the voice information of the external person is obtained through the voice module 23, or the azimuth information or the lip movement information of the external person and the voice information of the external person are collected simultaneously through the camera 22 and the voice module 23, and the final control signal is determined according to the comparison, and the control signal is fed back or transmitted to the controller. When the controller receives the control signal, it determines whether the control signal is a forward rotation signal or a reverse rotation signal.

[0122] After the controller determines the rotation signal, it transmits the signal to the lifting assembly 31, so that the controller controls the lifting assembly 31 to drive the transmission member 32 or the driving member to move to the target position according to the forward rotation signal or the reverse rotation signal. It can be understood that the target position is the first engagement position 334 or the second engagement position 335.

[0123] In this embodiment, the controller drives the transmission member 32 to move to the target position by the lifting assembly 31, so that the transmission teeth 327 of the transmission member 32 engage with the driving gear 33; or the controller drives the driving member to move to the target position by the lifting assembly 31, so that the transmission teeth 327 of the transmission member 32 engage with the driving gear 33.

[0124] It can be understood that the driving gear 33 has opposite first and second meshing positions 334 and 335. The connection line between the first meshing position 334 and the second meshing position 335 passes through the rotation center of the rotating disk 331 of the driving gear 33 and is parallel to the axial direction of the transmission member 32. In this way, it can be ensured that the teeth 332 at the first meshing position 334 or the second meshing position 335 of the rotating disk 331 mesh with the transmission teeth 327. Thus, when the driving member drives the rotating disk 331 of the driving gear 33 to drive a plurality of teeth 332 to rotate, when the transmission teeth 327 mesh with the teeth 332 of the driving gear 33, the transmission member 32 and the housing 21 are driven to rotate.

[0125] In this embodiment, the controller controls the lifting assembly 31 to drive the transmission member 32 to move to a target position according to a forward rotation signal or a reverse rotation signal.

[0126] In one embodiment, before the step of controlling the lifting assembly 31 to drive the transmission member 32 to move to a target position according to a forward rotation signal or a reverse rotation signal, it further includes:

[0127] Obtain the position information of the transmission teeth 327. The controller receives the position information and controls the lifting assembly 31 to drive the transmission member 32 or the driving member to move, so that the transmission teeth 327 or the driving member move from the position information to the target position.

[0128] It can be understood that the camera adjustment system 100 is provided with a displacement detection member for detecting the position information of the transmission teeth 327. The position information of the transmission teeth 327 is obtained through the displacement detection member and transmitted to the controller. After receiving the position information, the controller controls the lifting assembly 31 to drive the transmission member 32 or the driving member to move, so that the transmission teeth 327 or the driving member move from the position information to the target position.

[0129] In this embodiment, the rotating disk 331 of the driving gear 33 has opposite first and second meshing positions 334 and 335. That is, the first meshing position 334 and the second meshing position 335 are arranged at intervals along the axial direction of the transmission member 32 on the rotating disk 331 of the driving gear 33, and are located in the regions corresponding to two fixed positions in the physical space when the rotating disk 331 rotates, rather than two fixed and unchanging regions on the rotating disk 331.

[0130] It can be understood that when the displacement detection component detects that the transmission tooth 327 is in the first meshing position 334 and the transmission tooth 327 meshes with the driving gear 33 at the first meshing position 334, the controller receives a control signal and determines whether the control signal is a forward rotation signal or a reverse rotation signal. When the control signal is a forward rotation signal, the controller controls the driving component to drive the driving gear 33 to rotate at this time, so that the driving gear 33 drives the transmission component 32 and the imaging component 2 to rotate forward. Of course, when the control signal is a reverse rotation signal, the controller controls the lifting component 31 to drive the transmission component 32 to move to the target position (i.e., the second meshing position 335) according to the reverse rotation signal, so that the transmission tooth 327 of the transmission component 32 meshes with the driving gear 33 at the second meshing position 335. Then, the controller controls the driving component to drive the driving gear 33 to rotate, so that the driving gear 33 drives the transmission component 32 and the imaging component 2 to rotate in reverse.

[0131] Alternatively, when the displacement detection component detects that the transmission tooth 327 is in the second meshing position 335 and the controller receives a control signal as a forward rotation signal, the controller controls the lifting component 31 to drive the transmission component 32 to move to the target position (i.e., the first meshing position 334) according to the forward rotation signal, so that the transmission tooth 327 of the transmission component 32 meshes with the driving gear 33 at the first meshing position 334. Then, the controller controls the driving component to drive the driving gear 33 to rotate, so that the driving gear 33 drives the transmission component 32 and the imaging component 2 to rotate forward. When the control signal is a reverse rotation signal, the controller controls the driving component to drive the driving gear 33 to rotate at this time, so that the driving gear 33 drives the transmission component 32 and the imaging component 2 to rotate in reverse.

[0132] It should be noted that when the displacement detection component detects that the transmission tooth 327 is in a position other than the first meshing position 334 and the second meshing position 335, and the controller receives a control signal as a forward rotation signal, the controller controls the lifting component 31 to drive the transmission component 32 to move to the target position (i.e., the first meshing position 334) according to the forward rotation signal, so that the transmission tooth 327 of the transmission component 32 meshes with the driving gear 33 at the first meshing position 334. Then, the controller controls the driving component to drive the driving gear 33 to rotate, so that the driving gear 33 drives the transmission component 32 and the imaging component 2 to rotate forward. Alternatively, when the control signal is a reverse rotation signal, the controller controls the lifting component 31 to drive the transmission component 32 to move to the target position (i.e., the second meshing position 335) according to the reverse rotation signal, so that the transmission tooth 327 of the transmission component 32 meshes with the driving gear 33 at the second meshing position 335. Then, the controller controls the driving component to drive the driving gear 33 to rotate, so that the driving gear 33 drives the transmission component 32 and the imaging component 2 to rotate in reverse.

[0133] In one embodiment, before the step of controlling the lifting component 31 to drive the transmission component 32 to move to the target position according to the forward rotation signal or the reverse rotation signal, it further includes:

[0134] The transmission gear 327 has an initial position, which is the first meshing position 334 or the second meshing position 335; among them, the initial position is different from the target position.

[0135] It can be understood that the transmission gear 327 of the transmission member 32 has an initial position, that is, when the camera adjustment system 100 is powered on, the transmission gear 327 is located at the initial position, which can be the position where the transmission gear 327 was located when the camera adjustment system 100 was last turned off during the previous use. In order to improve the operation simplicity, the initial position is the first meshing position 334 or the second meshing position 335, that is, when the camera adjustment system 100 is powered on, the transmission gear 327 is located at the first meshing position 334 or the second meshing position 335.

[0136] When the initial position of the transmission gear 327 is the first meshing position 334, the position information of the transmission gear 327 is detected and obtained by the displacement detection member, and then the controller receives the position information. When the controller receives the control signal and determines whether the control signal is a forward rotation signal or a reverse rotation signal, when the control signal is a forward rotation signal, at this time, the controller controls the driving member to drive the driving gear 33 to rotate; so that the driving gear 33 drives the transmission member 32 and the camera assembly 2 to rotate forward. When the control signal is a reverse rotation signal, the controller controls the lifting assembly 31 to drive the transmission member 32 to move to the target position (that is, the second meshing position 335) according to the reverse rotation signal, so that the transmission gear 327 of the transmission member 32 meshes with the driving gear 33 at the second meshing position 335; then, the controller controls the driving member to drive the driving gear 33 to rotate; so that the driving gear 33 drives the transmission member 32 and the camera assembly 2 to rotate in the reverse direction.

[0137] When the initial position of the transmission gear 327 is the second meshing position 335, the position information of the transmission gear 327 is detected and obtained by the displacement detection member, and then the controller receives the position information. When the controller receives the control signal and determines whether the control signal is a forward rotation signal or a reverse rotation signal, when the control signal received by the controller is a forward rotation signal, the controller controls the lifting assembly 31 to drive the transmission member 32 to move to the target position (that is, the first meshing position 334) according to the forward rotation signal, so that the transmission gear 327 of the transmission member 32 meshes with the driving gear 33 at the first meshing position 334; then, the controller controls the driving member to drive the driving gear 33 to rotate; so that the driving gear 33 drives the transmission member 32 and the camera assembly 2 to rotate forward. When the control signal is a reverse rotation signal, at this time, the controller controls the driving member to drive the driving gear 33 to rotate; so that the driving gear 33 drives the transmission member 32 and the camera assembly 2 to rotate in the reverse direction.

[0138] In one embodiment, it is defined that when the transmission gear 327 meshes with the driving gear 33 at the first meshing position 334, the imaging assembly 2 rotates forward; when the transmission gear 327 meshes with the driving gear 33 at the second meshing position 335, the imaging assembly 2 rotates reversely.

[0139] According to the forward rotation signal or the reverse rotation signal, the steps of controlling the lifting assembly 31 to drive the transmission member 32 to move to the target position include:

[0140] When the control signal is a forward rotation signal, control the lifting assembly 31 to drive the transmission member 32 to move, so that the transmission gear 327 moves to the target position and meshes with the driving gear 33 at the first meshing position 334;

[0141] Or, when the control signal is a reverse rotation signal, control the lifting assembly 31 to drive the transmission member 32 to move, so that the transmission gear 327 moves to the target position and meshes with the driving gear 33 at the second meshing position 335.

[0142] It can be understood that the forward rotation signal is consistent with the forward rotation of the imaging assembly 2, and the reverse rotation signal is consistent with the reverse rotation of the imaging assembly 2. When the controller receives a control signal that is a forward rotation signal or a reverse rotation signal and obtains the position information of the transmission gear 327, the controller receives the position information and controls the lifting assembly 31 to drive the transmission member 32 to move, so that the transmission gear 327 moves from the position information to the target position, and the transmission gear 327 of the transmission member 32 meshes with the driving gear 33 at the first meshing position 334 or the second meshing position 335, and controls the driving member to drive the driving gear 33 to rotate, so that the driving gear 33 drives the transmission member 32 and the imaging assembly 2 to rotate forward or reversely.

Any equivalent structural transformation made under the concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present invention.
