Description

Technical Field

[0001] This utility model relates to the field of camera technology, and in particular to a camera that can automatically adjust its angle. Background Technology

[0002] Currently, most adjustable-angle camera devices in widely used self-service terminals are large and complex in structure. Chinese utility model patent CN 207037536 U discloses a novel tablet computer camera, including a display screen and an outer frame fixed around the screen. The outer frame has a camera window, and a cavity is formed inside the frame. An angle adjustment component is located within the cavity. The adjustment component includes a fixing plate fixed to the inner wall of the cavity, a rotating shaft mounted on the fixing plate, and a camera mounted on the shaft. A micro motor is connected to the left end of the rotating shaft and is electrically connected to the computer motherboard. The micro motor controls the rotation of the rotating shaft, thereby adjusting the camera angle. By using a micro motor to drive the rotating shaft, the camera angle is adjusted, resulting in a smaller overall size.

[0003] The above solution provides a good idea: miniaturizing the angle-adjustable camera using a micro motor. In this solution, the camera itself is very small, belonging to the category of micro cameras, so it can be directly mounted on the rotating shaft. However, for cameras with ordinary structures, not only does the camera itself include an integrated control motherboard, which cannot be directly integrated onto the rotating shaft. Furthermore, this solution only limits the camera's rotation angle range through a purely mechanical structure, which cannot cooperate with the motor to achieve automatic adjustment. An additional control device is still required to control the motor's rotation. Moreover, when the camera rotates to its limit, there will be a noticeable collision sound and pause between the limit block and the fixed plate, resulting in a poor user experience. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an automatically adjustable camera that can be applied to cameras with traditional structures. It can automatically control the camera's angle adjustment limit position, has a simple overall structure, and makes the entire forward and reverse rotation process of the camera quieter and smoother.

[0005] The technical solution to achieve the purpose of this utility model is:

[0006] An automatically adjustable camera includes an outer frame with a through slot in the middle. A first bracket and a second bracket are symmetrically mounted on the back of the outer frame on both sides of the through slot. A micro motor is fixedly mounted on the outer side of the first bracket. The motor shaft of the micro motor passes through the first bracket and is coaxially fixed to a rotating bracket. A camera assembly is mounted on the rotating bracket, and the other end is rotatably mounted on the second bracket. An upper photoelectric switch and a lower photoelectric switch connected to the micro motor are provided on the inner side of the second bracket along the rotation direction of the rotating bracket. A trigger adapted to the upper and lower photoelectric switches is provided on the rotating bracket.

[0007] Furthermore, the end of the rotating bracket is provided with an arc plate coaxial with the rotation axis, and the trigger is a first trigger plate and a second trigger plate arranged radially on the outer circumferential surface of the arc plate, the first trigger plate and the second trigger plate extending to the upper photoelectric switch and the lower photoelectric switch respectively.

[0008] Furthermore, the outer side of the second bracket is provided with a first mounting post adapted to the micro motor, and the other end of the rotating bracket is provided with a mounting hole adapted to the motor shaft of the micro motor.

[0009] Furthermore, the rear side of the rotating bracket is provided with an inwardly recessed receiving cavity, and the two ends of the receiving cavity are provided with integrally formed second mounting posts. The camera assembly is located in the receiving cavity and both ends are provided with screws that are tightened onto the second mounting posts.

[0010] Furthermore, a boss integrally formed with the receiving cavity is provided between the two second mounting posts, and the boss is in contact with the camera assembly.

[0011] Furthermore, the top and bottom of the receiving cavity are both arc surfaces, and the two arc surfaces are respectively clearance-fitted with the top and bottom surfaces of the through groove with a gap of less than 1mm.

[0012] Furthermore, both of the two arc surfaces are provided with retaining edges on their outer sides, and the two retaining edges are higher and lower than the top and bottom of the through groove, respectively, when the rotating bracket is rotated to two extreme positions.

[0013] By adopting the above technical solution, this utility model has the following beneficial effects:

[0014] (1) This utility model controls the rotation of the rotating bracket by a micro motor, thereby driving the rotation of the camera component installed on it. It has a greater tolerance for the size of the camera component and a wider range of application scenarios. Through the photoelectric switch and trigger working together, the limit rotation angle of the rotating bracket is controlled, thereby realizing the automatic adjustment of the angle of the camera component. Compared with the traditional pure mechanical limit, the overall structure is simple and the entire forward and reverse rotation process of the camera component is quieter and smoother.

[0015] (2) By setting two trigger plates to sense the upper photoelectric switch and the lower photoelectric switch respectively, the installation position of the upper photoelectric switch and the lower photoelectric switch is more flexible and the overall thickness is smaller, which is also applicable to installation positions with limited space.

[0016] (3) The present invention is pre-installed with a first mounting column adapted to the micro motor, and the other end of the rotating bracket is provided with a mounting hole adapted to the motor shaft of the micro motor, so as to realize the reversing installation of the micro motor and meet the needs of more installation scenarios.

[0017] (4) The rotating bracket of this utility model is provided with a receiving cavity to realize the semi-enclosed installation of the camera component, which has a stronger overall feel. The second mounting column is reserved to facilitate the installation of the camera component.

[0018] (5) This utility model provides a good shock absorption effect by setting a protrusion that fits with the camera component, thus avoiding shaking.

[0019] (6) The rotating bracket of this utility model has an arc surface that matches the through groove, which avoids the occurrence of large gaps that may cause foreign objects to enter and cause rotational jamming, and at the same time makes the appearance more beautiful.

[0020] (7) This utility model achieves mechanical limiting by adding a stop, which prevents the camera from being damaged due to excessive rotation angle after the photoelectric switch malfunctions. Attached Figure Description

Detailed Implementation

[0029] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0030] (Example 1)

[0031] like Figures 1 to 5 The automatically adjustable camera shown includes an outer frame 1, a first bracket 2, a second bracket 3, a micro motor 4, a rotating bracket 5, a camera assembly 6, an upper photoelectric switch 7, a lower photoelectric switch 8, and a trigger 9. The outer frame 1 has a rectangular through-slot 1-1 in the middle. The first bracket 2 and the second bracket 3 are fixedly mounted on the back of the outer frame 1 and symmetrically arranged on both sides of the through-slot 1-1. The micro motor 4 is fixedly mounted on the outside of the first bracket 2, with its shaft passing through the first bracket 2 and coaxially connected to one end of the rotating bracket 5. The other end of the rotating bracket 5 is rotatably mounted on the second bracket 3. The camera assembly 6 is mounted on the rotating bracket 5. The rotation of the rotating bracket 5 is controlled by the micro motor 4, thereby driving the rotation of the camera assembly 6 mounted on it. This design offers greater tolerance for the size of the camera assembly 6 and allows for a wider range of applications. Both the upper photoelectric switch 7 and the lower photoelectric switch 8 are connected to the micro motor 4 and are installed on the inner side of the second bracket 3 and distributed along the rotation direction of the rotating bracket 5. The trigger 9 is set on the rotating bracket 5 and is adapted to the upper photoelectric switch 7 and the lower photoelectric switch 8. It is used to trigger the photoelectric switch during the rotation of the rotating bracket 5, thereby controlling the limit rotation angle of the rotating bracket 5, and thus realizing the automatic adjustment of the angle of the camera component 6. Compared with the traditional pure mechanical limit, the overall structure is simple and the entire forward and reverse rotation process of the camera component is quieter and smoother.

[0032] Specifically, the end of the rotating bracket 5 is provided with an arc plate 5-1 coaxial with the rotation axis. The trigger 9 consists of a first trigger plate 9-1 and a second trigger plate 9-2 arranged radially on the outer circumference of the arc plate 5-1. The first trigger plate 9-1 and the second trigger plate 9-2 extend to the upper photoelectric switch 7 and the lower photoelectric switch 8, respectively. The two trigger plates sense the two photoelectric switches respectively, making the installation position of the two photoelectric switches more flexible and the overall thickness smaller. It is also suitable for installation positions with limited space.

[0033] The rear side of the rotating bracket 5 has an inwardly recessed receiving cavity. At both ends of the receiving cavity are integrally formed second mounting posts 5-2. The camera assembly is housed within the receiving cavity, and both ends are secured with screws tightened onto the second mounting posts 5-2, achieving a semi-enclosed installation for a more cohesive look. Between the second mounting posts 5-2 is an integrally formed boss 5-3, which fits snugly against the camera assembly 6, providing excellent shock absorption and preventing wobbling. The top and bottom of the receiving cavity are both arc-shaped surfaces, which fit with the top and bottom surfaces of the through groove 1-1 with a gap of less than 1mm, preventing excessive gaps that could allow foreign objects to enter and cause rotational jamming, while also enhancing the aesthetics of the design.

[0034] Considering that the photoelectric switch may malfunction and lose its sensing function after long-term use, in order to prevent the camera assembly from being damaged due to excessive rotation, this embodiment provides a stop 5-4 on the outer side of both arc surfaces. When the rotating bracket 5 rotates to the two extreme positions, the two stop 5-4 are higher and lower than the top and bottom of the through groove 1-1, respectively, thereby achieving mechanical limiting and improving safety in use.

[0035] The outer side of the second bracket 3 is provided with a first mounting post 3-1 that is compatible with the micro motor 4, and the other end of the rotating bracket 5 is provided with a mounting hole 5-5 that is compatible with the motor shaft of the micro motor 4, reserving a second mounting position for the micro motor 4 to realize the reverse installation of the micro motor and meet the needs of more installation scenarios.

[0036] In this embodiment, the rotation of the rotating bracket 5 is controlled by the micro motor 4, which in turn drives the rotation of the camera component 6 mounted on it. This provides greater tolerance for the size of the camera component 6 and allows for a wider range of applications. Through the cooperation of photoelectric switches and triggers, the limit rotation angle of the rotating bracket 5 is controlled, thereby achieving automatic angle adjustment of the camera component 6. Compared with the traditional purely mechanical limit, the overall structure is simpler, and the entire forward and reverse rotation process of the camera component is quieter and smoother.

[0037] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
