Description

Technical Field

[0001] This application belongs to the field of camera equipment technology, and specifically relates to a camera. Background Technology

[0002] As an imaging device, cameras are increasingly being used in home environments. For example, cameras can be used to record life by shooting videos, monitor the situation of elderly people or children at home, and conduct security monitoring when no one is home.

[0003] In practical applications, due to the limited field of view of the camera, users can usually only choose one optimal shooting position. However, this shooting position is often affected by many external factors, such as manually adjusting the camera's field of view, which causes the shooting position to change. However, if the user wants to adjust the camera's shooting position back to the initial shooting position, the user needs to make multiple adjustments, which is a cumbersome process and has low work efficiency. Utility Model Content The purpose of this application is to provide a camera that can solve the problem of cumbersome adjustment of the shooting field of view of current cameras.

[0004] To solve the above-mentioned technical problems, this application is implemented as follows: This application provides a camera, including a base, a lens assembly, a first position detection component, a first drive component, and a control component. The lens assembly is movably disposed on the base, and the first drive component is disposed on the base. The output shaft of the first drive component is connected to the lens assembly. The first position detection component is used to detect first position information of the lens assembly relative to the base. Both the first position detection component and the first drive component are electrically connected to the control component. The control component is used to control the first drive component to drive the lens assembly to rotate relative to the base about a first axis according to the first position information, so that the field of view of the lens assembly rotates to a preset position.

[0005] In this embodiment, a first position detection component is set to detect the first position information of the lens assembly relative to the base. During the operation of the camera, once the lens assembly is manually rotated, causing the field of view of the lens assembly to deviate from the preset position, the control component controls the first driving component to drive the lens assembly to rotate around the first axis relative to the base according to the first position information detected by the first position detection component, so that the field of view of the lens assembly returns to the preset position. That is, the camera performs automatic correction, so that the field of view of the lens assembly returns to the best shooting position initially selected by the user, without the user having to manually adjust it multiple times to find the preset position of the lens assembly again. This can greatly reduce the difficulty of adjusting the shooting field of view of the camera. Attached Figure Description

[0009] The camera provided in the embodiments of this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0010] like Figures 1 to 11 As shown in the illustration, this application discloses a camera, which includes a base 100, a lens assembly 200, a first position detection component 300, a first drive component 400, and a control component. The lens assembly 200 is movably disposed on the base 100, and the first drive component 400 is disposed on the base 100. The base 100 serves as a foundation component, providing a mounting base for structures such as the lens assembly 200 and the first drive component 400. Optionally, the base 100 can be mounted to a mounting base (such as a wall, support frame, etc.) using fasteners such as screws. Optionally, the first drive component 400 can be a drive device such as a motor; this application embodiment does not impose specific limitations on this. The output shaft of the first drive component 400 is connected to the lens assembly 200, and the first drive component 400 can drive the lens assembly 200 to rotate around a first axis to adjust the shooting angle of the lens assembly 200. The first position detection component 300 is used to detect the first position information of the lens assembly 200 relative to the base 100. Both the first position detection component 300 and the first driving component 400 are electrically connected to a control component. The control component controls the first driving component 400 to drive the lens assembly 200 to rotate relative to the base 100 around a first axis according to the first position information, so that the field of view of the lens assembly 200 rotates to a preset position. This preset position is the target position that the lens assembly 200 needs to capture, set by the user. Optionally, the first axis can be perpendicular to the horizontal plane, parallel to the horizontal plane, or inclined relative to the horizontal plane. This embodiment does not impose specific limitations on these aspects.

[0011] In this embodiment, a first position detection component 300 is set to detect the first position information of the lens assembly 200 relative to the base 100. During camera operation, if the lens assembly 200 is manually rotated, causing the field of view of the lens assembly 200 to deviate from the preset position, the control component controls the first driving component 400 to drive the lens assembly 200 to rotate around the first axis relative to the base 100, so that the field of view of the lens assembly 200 returns to the preset position. That is, the camera performs automatic correction, so that the field of view of the lens assembly 200 returns to the preset position initially selected by the user, without requiring the user to manually adjust the lens assembly 200 multiple times to find the preset position again. This can greatly reduce the difficulty of adjusting the shooting field of view of the camera. Therefore, this embodiment can solve the problem of cumbersome adjustment of the shooting field of view of current cameras.

[0012] In an optional embodiment, the lens assembly 200 includes a bracket 210, a lens 220, a second position detection component 230, and a second drive member 240. The lens 220 is rotatably connected to the bracket 210, and the output shaft of the first drive member 400 is connected to the bracket 210. Optionally, the lens 220 and the first drive member 400 can be respectively disposed on opposite sides of the bracket 210, and the first drive member 400 can be located within the receiving space enclosed by the bracket 210 and the base 100 to protect the first drive member 400. Further optionally, the first drive member 400 includes a connected drive source, a first gear, and a second gear. The first gear is sleeved on the connecting shaft of the bracket 210, and the second gear is sleeved on the output shaft of the drive source. The first gear and the second gear mesh, and the drive source drives the lens assembly 200 to rotate around a first axis through the first gear and the second gear. The output shaft of the second drive member 240 is connected to the lens 220. Optionally, the second drive member 240 can be disposed on the bracket 210. Further optionally, the second drive member 240 can be a ring driver. The second position detection component 230 is used to detect the second position information of the lens 220 relative to the base 100. Both the second position detection component 230 and the second drive component 240 are electrically connected to a control component. The control component controls the second drive component 240 to drive the lens 220 to rotate relative to the base 100 around a second axis, so that the field of view of the lens 220 is rotated to a preset position, wherein the second axis intersects the first axis. When it is necessary to adjust the field of view of the lens 220 to the preset position, the first drive component 400 can first drive the lens assembly 200 to rotate around the first axis, and then the second drive component 240 can drive the lens 220 to rotate relative to the bracket 210 around the second axis, so that the field of view of the lens 220 is rotated to the preset position. In other words, this solution improves the flexibility and accuracy of the camera's field of view adjustment by adjusting the position of the lens 220 from different directions. Of course, the second driving component 240 can be omitted, and the lens 220 can be rotated by the first driving component 400 to adjust the field of view position of the lens 220.

[0013] Optionally, the second axis can be perpendicular to the horizontal plane, or the second axis can be parallel to the horizontal plane, and the first axis can also be inclined relative to the horizontal plane. This application embodiment does not impose specific limitations on this.

[0014] Optionally, the angle between the second axis and the first axis can be acute; or, the second axis can be set perpendicular to the first axis. In this case, the range of rotation of the adjustment lens 220 can be greater, so as to further improve the flexibility and accuracy of adjusting the field of view position of the camera. Optionally, the camera is used to communicate with the display device in a switchable manner. When the camera is in shooting mode, the control unit communicates with the display device so that the captured image is displayed on the display device. When the camera is in privacy protection mode, the control unit is disconnected from the display device. At this time, the display device does not display the captured image, but the lens assembly 200 may still be in shooting mode.

[0015] Based on this, in a further optional embodiment, the lens assembly 200 further includes a housing 250, which is disposed on the bracket 210. The lens 220, the second position detection component 230, and the second driving component 240 are all located within the receiving cavity of the housing 250. In this case, the housing 250 can protect the lens 220, the second position detection component 230, and the second driving component 240, preventing damage to these structures. The housing 250 is provided with a shooting window 251 to obtain light from the external environment. Optionally, the shooting window 251 can be an open structure or a light-transmitting structure (such as glass), and this application embodiment does not impose specific limitations on this. The second driving component 240 can drive the lens 220 to rotate relative to the base 100 around the second axis, so that at least a portion of the light-incident surface of the lens 220 faces the shooting window 251 or the light-incident surface of the lens 220 is blocked by the housing 250. When the camera is in shooting mode, at least a portion of the light-incident surface faces the shooting window 251 to obtain light from the external environment, thereby obtaining a shooting image. The control component is also connected to the display device to display the shooting image on the display device, so that the user can view it at any time. When the camera is in privacy protection mode, the light-incident surface is blocked by the housing 250. At this time, light from the external environment cannot enter the lens 220, that is, the lens 220 cannot capture the image outside the housing 250. The control component is disconnected from the display device, and the display device does not display the image captured by the lens 220, thus achieving dual protection to improve the privacy protection performance of the camera.

[0016] Optionally, the housing 250 includes a first housing 253 and a second housing 254 that are detachably connected. The first housing 253 and the second housing 254 are arranged opposite to each other to form the aforementioned receiving cavity, which facilitates the installation of structures such as the lens 220, the second position detection component 230, and the second drive component 240. Both the first housing 253 and the second housing 254 are detachably connected to the bracket 210 so that the housing 250 is fixed relative to the bracket 210. Optionally, the second axis can be located in a vertical plane, in which case the second drive member 240 can drive the lens 220 to rotate in the horizontal plane; or, in other optional embodiments, the second axis is located in a horizontal plane, in which case the second drive member 240 can drive the lens 220 to rotate in the vertical plane, that is, drive the lens 220 to perform pitch movement. The housing 250 is also provided with a light-shielding area 252, and the shooting window 251 is located between the light-shielding area 252 and the base 100. In this case, the shooting window 251 is located at a lower position in the vertical direction. When the light-incident surface of the lens 220 faces the shooting window 251, the angle between the optical axis of the lens 220 and the horizontal plane is smaller, which facilitates the shooting of the lens 220; at the same time, it facilitates the connection between the second drive member 240 and the lens 220 to drive the lens 220 to rotate around the second axis. Of course, the base 100 or the bracket 210 can also be used as a light-shielding structure to block the light-incident surface of the lens 220.

[0017] When the camera is in privacy protection mode and at least a portion of the light-incident surface of the lens 220 faces the shooting window 251, the second drive member 240 can drive the lens 220 to rotate relative to the base 100, so that the light-incident surface is blocked by the light-blocking area 252. When the camera is in privacy protection mode, the lens 220 is manually driven to rotate from the light-blocking area 252 to the shooting window 251. Although the camera is disconnected from the display device, the lens 220 may still be in the shooting state. When the second position information of the lens 220 detected by the second position detection component 230 shows that the light-incident surface of the lens 220 is facing the shooting window 251, the control member drives the lens 220 to rotate around the second axis according to the second position information detected by the second position detection component 230, so that the light-incident surface of the lens 220 is blocked by the light-blocking area 252, that is, the light-incident surface of the lens 220 is opposite to the light-blocking area 252, so that the lens 220 is back in the dual protection mode, thereby improving the privacy protection performance of the camera. In one optional embodiment, the first position information is the rotation angle of the lens assembly 200 relative to the base 100 around a first axis from a preset position to the current position. Here, the current position refers to the position of the lens assembly 200 relative to the base 100 at the moment the first position detection component 300 performs a detection operation. When the first drive component 400 is a motor, the number of rotations or angles required for the output shaft of the first drive component 400 to rotate can be directly calculated from the rotation angle of the lens assembly 200. This simplifies the calculation process of the control component, thereby reducing the design difficulty of the camera. Of course, the first position information can also be the rotation arc length of the lens assembly 200 relative to the base 100 from a preset position to the current position, or it can be the relative positional relationship between the lens assembly 200 and a certain structure of the base 100.

[0018] Optionally, the first position detection component 300 can be photoelectric detection; or, in a further optional embodiment, the first position detection component 300 includes a magnetic ring 310 and a magnetic sensor 320. The magnetic sensor 320 is electrically connected to the control component. One of the magnetic ring 310 and the magnetic sensor 320 is disposed on the lens assembly 200, and the other is disposed on the base 100. The central axis of the magnetic sensor 320, the central axis of the magnetic ring 310, and the first axis of the lens assembly 200 are collinear. When the lens assembly 200 rotates relative to the base 100 around the first axis, the magnetic ring 310 and the magnetic sensor 320 rotate relative to each other. During this process, there is only an angular difference between the magnetic ring 310 and the magnetic sensor 320, and the distance between them remains unchanged. The magnetic sensor 320 is used to detect the magnetic flux of the magnetic ring 310 to obtain the rotation angle of the lens assembly 200. That is, the first position detection component 300 adopts electromagnetic detection, which has the characteristics of strong anti-interference ability, high detection accuracy and sensitivity, simple detection structure, low cost and convenient maintenance. Therefore, the first position detection component 300 in this solution uses the aforementioned magnetic ring 310 and magnetic sensor 320 for detection to obtain the rotation angle of the lens assembly 200, which is beneficial to improving the rotation accuracy of the lens assembly 200.

[0019] Optionally, the magnetic ring 310 is disposed on the lens assembly 200, and the magnetic sensor 320 is disposed on the base 100. Since the magnetic sensor 320 needs to be connected to the control unit via a wire, and the magnetic ring 310 is only used to provide a magnetic field, disposing of the magnetic ring 310 on the lens assembly 200 allows the magnetic ring 310 to rotate together with the lens assembly 200. Alternatively, the magnetic ring 310 can be disposed on the base 100, and the magnetic sensor 320 on the lens assembly 200.

[0020] Optionally, the first position detection component 300 further includes a circuit board 330. The magnetic sensor 320 is connected to the base 100 via the circuit board 330, and the magnetic sensor 320 is electrically connected to the control component via the circuit board 330. In this case, the circuit board 330 is connected to the control component via wires. Optionally, the magnetic sensor 320 is soldered onto the circuit board 330 using SMT (Surface Mount Technology) to improve the structural compactness between the two.

[0021] Optionally, in an embodiment where the lens assembly 200 includes a bracket 210, a lens 220, a second position detection component 230, and a second drive component 240, the second position information of the second position detection component 230 is the rotation angle of the lens 220 relative to the base 100 about a second axis from a preset position. The second position detection component 230 can have the same structure as the first position detection component 300, that is, the second position detection component 230 includes a magnetic ring 310 and a magnetic sensor 320. In this case, the magnetic sensor 320 of the second position detection component 230 is electrically connected to the control component. One of the magnetic ring 310 and the magnetic sensor 320 of the second position detection component 230 is disposed on the lens 220, and the other is disposed on the bracket 210. The central axis of the magnetic sensor 320, the central axis of the magnetic ring 310, and the second axis of the lens 220 are collinear. When the lens 220 rotates relative to the base 100 around the second axis, the magnetic ring 310 and the magnetic sensor 320 of the second position detection component 230 rotate relative to each other. The magnetic sensor 320 is used to detect the magnetic flux of the magnetic ring 310 to obtain the rotation angle of the lens 220, thereby improving the rotation accuracy of the lens 220.

[0022] In another optional embodiment, the lens assembly 200 can rotate in a horizontal plane around a first axis between a first extreme position and a second extreme position. A first rotation angle exists between the preset position and the first extreme position. A second rotation angle exists between the current position of the lens assembly 200 (the position information detected by the first position detection component 300 as the lens assembly 200 rotates to its current position in the horizontal plane around the first axis can be the first position information described above) and the first extreme position. Here, the current position refers to the position of the lens assembly 200 relative to the base 100 at the moment the first position detection component 300 performs the detection operation. When the second rotation angle is less than the first rotation angle, the first driving member 400 can drive the lens assembly 200 to rotate relative to the base 100 around the first axis in a first direction; when the second rotation angle is greater than the first rotation angle, the first driving member 400 can drive the lens assembly 200 to rotate relative to the base 100 around the first axis in a second direction, wherein the first direction and the second direction are opposite. In other words, the first driving component 400 can drive the lens assembly 200 to rotate clockwise and counterclockwise relative to the base 100 around the first axis in two directions, thereby improving the rotational flexibility of the lens assembly 200 during the rotation process. Of course, the lens assembly 200 can also rotate relative to the base 100 around the first axis in only one direction. In this case, the rotation range of the lens assembly 200 is 360°, and its rotation angle is large and the time is long.

[0023] Optionally, the angle between the first extreme position and the second extreme position can be 300~330° to expand the rotation range of the lens assembly 200 in the horizontal plane.

[0024] In one optional embodiment, the camera further includes a recognition device disposed on the lens assembly 200 and electrically connected to a control unit. The recognition device identifies the source of the driving force experienced by the lens assembly 200 during rotation, specifically whether the driving force originates from the first driving member 400 or from a person. The control unit controls the first driving member 400 to rotate the lens assembly 200 relative to the base 100 based on the first recognition information from the recognition device, thereby rotating the lens assembly 200 to a preset position. This solution improves the camera's intelligence and the timeliness of the lens assembly 200's rotation by identifying whether the rotation of the lens assembly 200 is driven by a person. For example, if the user is not viewing the captured image on the display device and is unaware that the lens assembly 200 has been manually rotated, the control unit can control the first driving member 400 to rotate the lens assembly 200 relative to the base 100 based on the first position information detected by the first position detection component 300, allowing the lens assembly 200 to quickly return to the preset position. Of course, human judgment can also be used.

[0025] And / or, in another optional embodiment, the camera further includes an acoustic device 500. Optionally, the acoustic device 500 can be a speaker. The acoustic device 500 can be disposed within the receiving cavity of the housing 250 of the lens assembly 200. The acoustic device 500 is electrically connected to a control unit, which controls the acoustic device 500 to emit a prompt message based on the second identification information of the identification device. When the control unit controls the first drive member 400 to rotate, and after multiple attempts the first drive member 400 still cannot rotate back to the preset position, the camera may be damaged. The control unit will then control the acoustic device 500 to emit a prompt message based on the second identification information of the identification device to inform the user that the camera's shooting position has changed and that the lens assembly 200 cannot rotate on its own, thereby improving the camera's safety. Of course, it can also be checked manually.

[0026] Optionally, the first position detection component 300 can obtain a preset position of the lens assembly 200 based on the amount of change in the current position information of the lens assembly 200 detected by itself. However, when the lens assembly 200 rotates multiple times, the preset position information of the lens assembly 200 obtained by the first position detection component 300 is prone to deviation. Based on this, in another optional embodiment, the camera further includes a position information register, which is electrically connected to the control component. The position information register is used to record the preset position information of the lens assembly 200 detected by the first position detection component 300. The control component is used to control the first drive component 400 to drive the lens assembly 200 to rotate relative to the base 100 according to the first position information and the preset position information, so that the lens assembly 200 rotates to the preset position. When the control component controls the first drive component 400 to drive the lens assembly 200 to rotate, the first position information of the lens assembly 200 can be compared with the preset position information recorded by the position information register, thereby improving the rotation accuracy of the lens assembly 200. This solution ensures the accuracy of preset position information by setting a position information register, while also simplifying the design of the first position detection component 300.

[0027] Based on the camera provided in this application, the control method is as follows: The control method for rotating the lens assembly 200 about a first axis in the horizontal plane specifically includes: S110. The user selects a preset position of the lens assembly 200 in the horizontal plane on the display device and makes adjustments. The position information register records the preset position information of the lens assembly 200 detected by the first position detection component 300, and at the same time records the angle difference between the magnetic ring 310 and the magnetic sensor 320 of the first position detection component 300 (the latest angle difference will overwrite the previously recorded angle difference).

[0028] S120. When the lens assembly 200 is manually driven to rotate, the identification device identifies that the driving force acting on the lens assembly 200 does not come from the first driving member 400, that is, it is not controlled by the control member, but is manually driven. After the identification device identifies that the driving force acting on the lens assembly 200 disappears quickly, the control member controls the first driving member 400 to drive the lens assembly 200 to rotate relative to the base 100 according to the first identification information of the identification device, so that the lens assembly 200 rotates back to the preset position. Optionally, the first rotation angle between the preset position and the first limit position of the lens assembly 200 before it is manually driven to rotate is θ; S130, if the second rotation angle between the current position and the first extreme position of the lens assembly 200 is θ1, then the first driving member 400 drives the lens assembly 200 to rotate counterclockwise by an angle of θ - θ1. S140, if the second rotation angle between the current position and the first extreme position of the lens assembly 200 is θ2, then the first driving member 400 drives the lens assembly 200 to rotate clockwise by an angle of θ2 - θ.

[0029] It should be noted that when the lens assembly 200 is in the first extreme position, the angle difference between the magnetic ring 310 and the magnetic sensor 320 of the first position detection assembly 300 is 0°.

[0030] S150. If the identification device detects that the driving force acting on the lens assembly 200 has not disappeared, and the control unit attempts to control the first driving unit 400 to drive the lens assembly 200 to rotate multiple times but still fails to rotate, the control unit controls the acoustic device 500 to issue a prompt.

[0031] The specific method for controlling the rotation of the lens assembly 200 in the vertical plane about the second axis includes: S210. The user selects and adjusts the preset position of the lens assembly 200 in the vertical plane on the display device. The position information register records the preset position information of the lens 220 detected by the second position detection component 230, and at the same time records the angle difference between the magnetic ring and the magnetic sensor of the second position detection component 230 (the latest angle difference will overwrite the previously recorded angle difference).

[0032] S220. When the lens 220 is manually driven to rotate, the identification device identifies that the driving force acting on the lens 220 does not come from the second driving member 240, that is, it is not controlled by the control member, but is manually driven. After the identification device identifies that the driving force acting on the lens 220 disappears quickly, the control member controls the second driving member 240 to drive the lens 220 to rotate relative to the base 100 according to the first identification information of the identification device, so that the lens 220 rotates back to the preset position. S230. If the identification device detects that the driving force acting on the lens 220 has not disappeared, and the control unit attempts to control the second driving unit 240 to drive the lens 220 to rotate multiple times but still fails to rotate, the control unit controls the acoustic device 500 to issue a prompt.

[0033] When the camera is in shooting mode, the angle difference between the magnetic ring of the second position detection component 230 and the magnetic sensor is α; when the camera is in privacy protection mode, the camera control method is as follows: S240, the position information register records the angle difference α between the magnetic ring and the magnetic sensor of the second position detection component 230 when the camera is in shooting mode; S250. When the user sets the camera to enter privacy protection mode on the display device, the second driving component 240 drives the light-incident surface of the lens 220 to face the light-blocking area 252 so that the camera enters privacy protection mode. At this time, the angle difference between the magnetic ring and the magnetic sensor of the second position detection component 230 is β, and the control component is disconnected from the display device, and the display device displays a distorted screen state.

[0034] S260. When the user sets the camera to enter shooting mode on the display device, the second drive unit 240 drives the lens 220 to rotate to angle α so that the camera is in shooting mode.

[0035] S270. When the lens 220 is manually driven to rotate so that the light-incident surface faces the shooting window 251, if the recognition device detects that the driving force acting on the lens 220 disappears quickly, and the control unit and the display device are still disconnected, but the angle difference between the magnetic ring and the magnetic sensor of the second position detection component 230 is β, then the second driving unit 240 drives the lens 220 to rotate so that the light-incident surface is opposite to the light-blocking area 252, so as to block the light-incident surface. S280. If the identification device detects that the driving force acting on the lens 220 disappears quickly, and the control unit attempts to control the second driving unit 240 to drive the lens 220 to rotate multiple times but still fails to rotate, the control unit controls the acoustic device 500 to issue a prompt.

[0036] It should be noted that when the relative positions of the magnetic ring and the magnetic sensor of the second position detection component 230 are located at the connection between the shooting window 251 and the light-blocking area 252, the angle difference between the magnetic ring and the magnetic sensor of the second position detection component 230 is 0°.
