[0002] As a tool for acquiring and transmitting optical image signals, a camera's lens needs to rotate horizontally during use. In existing technology, the structure of a camera is relatively complex, and during the reciprocating rotation in the horizontal direction, its internal cables are easily pulled or twisted, which can lead to power loss between the cables and internal electronic components, shortening the camera's lifespan.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings. However, the exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein. The same reference numerals in the figures denote the same or similar structures, and therefore repeated descriptions of them will be omitted. The terms expressing position and direction described in the embodiments of this application are illustrative based on the accompanying drawings, but changes can be made as needed, and all such changes are included within the scope of protection of this application. The accompanying drawings of the embodiments of this application are only for illustrating relative positional relationships and do not represent actual scale.

[0023] It should be noted that specific details are set forth in the following description to facilitate understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0024] As a tool for acquiring and transmitting optical image signals, a camera's lens needs to rotate horizontally or vertically during use. In existing technology, to meet this rotation requirement, camera structures are typically quite complex, often incorporating internal gears. Furthermore, for some cameras without gear structures, the internal cables are easily pulled or twisted during horizontal reciprocating rotation, potentially causing power loss between the cables and electronic components, thus shortening the camera's lifespan.

[0025] In view of this, the imaging device provided by this utility model directly drives the lens rotation via a motor to simplify the camera structure. Simultaneously, the length of the camera's internal cable is increased, and both ends of the cable are connected to the side walls of the fixed and rotating parts of the camera, respectively. This reduces the risk of cable stretching or twisting, which could lead to power loss between the cable and electronic components, thus extending the camera's lifespan. To make the objectives, technical solutions, and advantages of this utility model clearer, the following will provide a more detailed description of this application in conjunction with the accompanying drawings and specific embodiments.

[0026] refer to Figure 1 and Figure 2 , Figure 1 Exploded view of the camera provided by this utility model; Figure 2 For display Figure 1 The provided image shows a cross-sectional view of a camera in an assembled state. The camera includes a fixed part 1 and a rotating part 2. The fixed part 1 is mounted on a wall or mounting bracket, and the fixed part 1 and the rotating part 2 are engaged to form a receiving cavity. In a specific configuration of the fixed part 1 and the rotating part 2, for example, the fixed part 1 may include a housing, and the rotating part 2 may also include a corresponding housing. The open ends of the two housings are engaged to form the aforementioned receiving cavity.

[0027] In addition, the camera also includes a motor 3 and a cable 4, both located within the receiving cavity. Specifically, the motor 3 may include a motor body 31 and a rotating shaft 32. The rotating shaft 32 is disposed on the motor body 31 and fixedly connected to the rotating part 2, while the motor body 31 is disposed on the fixed part 1 and fixedly connected to the fixed part 1, so as to drive the rotating part 2 to rotate relative to the fixed part 1 via the motor 3.

[0028] Understandably, since the lens and other related electronic components are located in the rotating part 2, the camera can acquire images from different angles during the rotation of the rotating part 2.

[0029] When configuring cable 4, please refer to the following: Figure 1 , Figure 2 and Figure 3 , Figure 3 For display Figure 1The bottom view shows the cable 4. One side of the cable 4 is connected to the first mounting position 11 of the fixing part 1, and the other side is connected to the second mounting position 21 of the rotating part 2. Specifically, a limiting silicone can be provided on the outer sheath of the cable 4, and the limiting silicone is an integral structure with the cable 4 to improve assembly convenience and connection strength. The first mounting position 11 and the second mounting position 21 can be through holes or limiting grooves, and the limiting silicone engages with the through holes or limiting grooves to achieve a stable connection between the two. At the same time, during the rotation of the rotating part 2 relative to the fixing part 1 around the axis of the rotating shaft 32, the cable 4 between the first mounting position 11 and the second mounting position 21 is always in a slack state. That is, if the straight-line distance between the first mounting position 11 and the second mounting position 21 is set to L1, and the length of the cable 4 between the first mounting position 11 and the second mounting position 21 is set to L2, then L1 and L2 satisfy: L1 < L2.

[0030] Understandably, the rotation angle of the rotating part 2 around the axis of the rotating shaft 32 is usually -180° to 180°. In addition, electronic devices are provided on both the fixed part 1 and the rotating part 2 (hereinafter, the electronic device provided on the fixed part 1 is referred to as the first device, and the electronic device provided on the rotating part 2 is referred to as the second device). The two ends of a cable 4 that are connected to the first mounting position 11 and the second mounting position 21, that is, the ends of the cable 4 that are away from the mounting positions, are electrically connected to the first device 12 and the second device respectively to realize the conduction between the two.

[0031] It should be noted that the first device 12 can be a power input terminal, a signal input terminal, a signal output terminal, a buzzer, or an indicator light, etc., which are existing technologies and will not be described in detail here. (See also...) Figure 3 and Figure 4 As shown, Figure 4 For display Figure 3 A partial schematic diagram of the provided camera. The aforementioned components can be fixedly connected to the side wall of the fixing part 1 via an adhesive dispensing process. Additionally, the cable 4 can also be fixedly connected to the first mounting position 11 of the fixing part 1 (e.g., any position on the side wall of the fixing part 1) via an adhesive dispensing process.

[0032] The camera provided by this invention simplifies the camera structure by placing the motor 3 on the fixed part 1 and directly driving the rotating part 2 to rotate. Simultaneously, the two sides of the cable 4 are mechanically connected to the first mounting position 11 and the second mounting position 21 respectively. During the rotation of the rotating part 2 relative to the fixed part 1, the cable 4 between the first mounting position 11 and the second mounting position 21 remains slack. This effectively reduces the risk of the cable 4 being stretched or twisted, thus preventing power loss between the cable 4 and electronic components, and extends the camera's service life.

[0033] It is worth mentioning that the camera may also include a cable channel 4, which is located inside the receiving cavity. The motor 3 is located outside the cable channel 4, and at least a portion of the cable 4 is connected to the first mounting position 11 of the fixed part 1 and the second mounting position 21 of the rotating part 2 via the cable channel 4. That is, the motor 3 and the cable 4 are located in different spaces, so as to effectively reduce the risk of the cable 4 getting tangled in the shaft 32 during the rotation of the rotating part 2 relative to the fixed part 1.

[0034] When configuring the 4-channel cable, the options are as follows: Please refer to [the relevant documentation / reference]. Figure 1 and Figure 2 The fixing part 1 may include a first limiting rib 13. For example, when the fixing part 1 is a housing, the housing may include a bottom wall and a side wall surrounding the bottom wall, and the first limiting rib 13 protrudes from the bottom wall and may be annular. Meanwhile, the rotating part 2 includes a second limiting rib 22, and the first limiting rib 13 and the second limiting rib 22 engage to form a first receiving space 5. The motor 3 is located in the first receiving space 5, and at least a portion of the cable 4 is located outside the first receiving space 5, so that the motor 3 and the cable 4 are located in different spaces, reducing the risk of the cable 4 getting tangled in the rotating shaft 32 while simplifying the camera structure.

[0035] It should be noted that the structure of the second limiting rib 22 can be referenced from the first limiting rib 13, and will not be described again here. Furthermore, the gap between the first limiting rib 13 and the second limiting rib 22 after they are engaged is smaller than the diameter of the cable 4, to reduce the risk of the cable 4 getting stuck in the gap and affecting the normal operation of the camera. In addition, the camera may include multiple cables 4, and the fixing part 1 may be provided with multiple first mounting positions 11. The first mounting position 11 may be located on the first limiting rib 13 or the side wall of the fixing part 1 used to surround the bottom wall. In this case, the end of the cable 4 installed at this mounting position can pass through the through hole on the first limiting rib 13 and be electrically connected to the motor body 31, while the other side of the cable 4 is connected to the second mounting position 21, and the end of the cable 4 near this side is electrically connected to the second device of the rotating part 2. Understandably, the first device 12 can also be the motor 3.

[0036] In one alternative implementation, such as Figure 2As shown, the rotating part 2 also includes a second receiving space 23, which is located outside the first receiving space 5 and is used to receive the second device. At least a portion of the cable 4 is located outside the first receiving space 5 and the second receiving space 23, while the second mounting position 21 is provided on the side wall of the second receiving space 23. Understandably, the side wall of the second receiving space 23 can be provided with a through hole, and one end of the cable 4 can extend into the second receiving space 23 to be electrically connected to the second device. Specifically, as described above, since the second mounting position 21 is provided on the side wall of the second receiving space 23, it can adopt the above-mentioned through hole structure, and the side wall of the through hole is provided with a certain length along the axial direction of the hole. The portion of the cable 4 passing through the through hole and the hole wall of the through hole are filled with positioning adhesive to achieve a fixed connection between the rotating part 2 and the cable 4. In addition, the end of the cable 4 extending into the second receiving space 23 is electrically connected to the second device, so as to achieve an electrical connection between the first device 12 and the second device, while reducing the risk of the cable 4 getting tangled in the second device and the cable 4 detaching from the second device due to pulling.

[0037] In one alternative implementation, such as Figure 1 As shown, the rotating part 2 may include an inner shell 24 and an outer shell 25, wherein the outer shell 25 is sleeved on the outside of the inner shell 24 and snaps into the inner shell 24 to achieve a quick connection between the two. Specifically, as shown... Figure 3 As shown, multiple slots 241 can be evenly distributed circumferentially on the side wall of the inner shell 24, and buckles (not shown in the figure) are provided at corresponding positions on the outer shell 25. It can be understood that the buckles can be set as elastic arms to improve the ease of connection between the inner shell 24 and the outer shell 25.

[0038] At the same time, such as Figure 2 As shown, the second mounting position 21 is located on the inner shell 24, and the side wall of the inner shell 24 is provided with a third limiting rib 242. The third limiting rib 242 protrudes towards the outer shell 25 and surrounds the second mounting position 21. The area enclosed by the third limiting rib 242 and the outer shell 25 is used to form a cable 4 channel. The cable 4 is connected to the second mounting position 21 through the cable 4 channel, which reduces the risk of the cable 4 getting tangled in the second device or the rotating shaft 32, while simplifying the camera structure.

[0039] It is worth mentioning that you should continue to refer to Figure 1 The third limiting rib 242 can be U-shaped, and the opening of the U-shape faces the fixing part 1. Then the cable 4 near the first mounting position 11 moves towards the bottom of the U-shape through the U-shaped opening. Understandably, the second mounting position 21 is close to the bottom of the U-shape, which helps to simplify the cable 4 channel structure.

[0040] like Figure 5 As shown, Figure 5 For display Figure 2A partial enlarged view at point A. In an optional embodiment, the fixing part 1 has a first annular surface 14 on the side facing the rotating part 2, and the rotating part 2 has a second annular surface 251 on the side facing the fixing part 1. At least a portion of the first annular surface 14 abuts against at least a portion of the second annular surface 251, and the first annular surface 14 and the second annular surface 251 surround the receiving cavity. It is understood that when the fixing part 1 is the aforementioned housing, and the housing includes a bottom wall and a side wall surrounding the bottom wall, the first annular surface 14 is the end face of the side wall facing away from the bottom wall. Similarly, when the rotating part 2 includes an inner shell 24 and an outer shell 25, the second annular surface 251 can be the end face of the side wall of the outer shell 25. When the housing and the outer shell 25 are engaged, at least a portion of the first annular surface 14 abuts against at least a portion of the second annular surface 251 to form the aforementioned receiving cavity.

[0041] And along the axial direction of the rotating shaft 32 (e.g.) Figure 2 or Figure 5 (As shown in the Z-axis direction), the inner edge of the second annular surface 251 is closer to the motor body 31 than the outer edge of the second annular surface 251. That is, the angle between the second annular surface 251 and the negative direction of the Z-axis is an acute angle α, and 80°≤α<90°. Since the axis of the rotating shaft 32 of the motor 3 is set along the direction of gravity during the use of the camera, by making the angle between the second annular surface 251 and the negative direction of the Z-axis an acute angle, water or other impurities falling into the second annular surface 251 can slide off the inclined plane by their own gravity, thereby effectively reducing the risk of water or other impurities entering the camera.

[0042] It is worth mentioning that the outer edge of the first annular surface 14 can be made closer to the outer edge of the second annular surface 251 relative to the inner edge of the first annular surface 14, that is, the angle between the first annular surface 14 and the negative direction of the Z-axis is also an acute angle α, and 80°≤α<90°, in order to further reduce the risk of water or other impurities entering the camera.

[0043] Alternatively, a gap can be made between the first annular surface 14 and the second annular surface 251, with a gap size of A and 0≤A≤0.8mm, to correct the skewness of the product appearance and improve the rotational accuracy of the camera's horizontal rotation when the first annular surface 14 and the second annular surface 251 are in contact.

[0044] It is worth mentioning that the surface roughness Ra of the first annular surface 14 and the second annular surface 251 can be set to be less than 0.8mm, in order to further improve the rotation accuracy of the camera's horizontal rotation and the camera's aesthetics.

[0045] In one alternative implementation, reference is also made to Figure 1 and Figure 2The rotating part 2 may also include a fourth limiting rib 252, which protrudes from the second annular surface 251 and is radially along the rotating shaft 32. The fourth limiting rib 252 is close to the rotating shaft 32 relative to the first annular surface 14, and there is a gap between the fourth limiting rib 252 and the first annular surface 14, so as to correct the skewness of the product appearance and improve the aesthetics of the camera during the horizontal rotation of the camera.

[0046] It is worth mentioning that the fourth limiting rib 252 can protrude more than 2mm from the second annular surface 251, which can effectively block water. In addition, the coaxiality of the fourth limiting rib 252 and the rotating shaft 32 is controlled within 0.25mm to further improve the rotational accuracy of the camera's horizontal rotation.

[0047] After understanding the mechanism of the camera provided by this utility model, the assembly process of the camera will be described below:

[0048] First, the motor 3 can be connected to the fixing part 1 (housing) using fasteners. Then, the rotating shaft 32 of the motor 3 can be inserted into the inner housing 24 of the rotating part 2, and the two can be fixedly connected using fasteners. At the same time, the cable 4 can be connected to the corresponding mounting position and electronic components. Then, the outer shell 25 can be pushed along the inner housing 24 toward the fixing part 1, so that the outer shell 25 is fitted onto the outside of the inner housing 24 and quickly snapped into place with the inner housing 24, thereby assembling the camera and improving assembly efficiency.

[0049] In summary, the camera provided by this utility model simplifies the camera structure by placing the motor 3 on the fixed part 1 and directly driving the rotating part 2 to rotate. Simultaneously, the two sides of the cable 4 are mechanically connected to the first mounting position 11 and the second mounting position 21 respectively. During the rotation of the rotating part 2 relative to the fixed part 1, the cable 4 between the first mounting position 11 and the second mounting position 21 remains slack. This effectively reduces the risk of the cable 4 being stretched or twisted, thus preventing power loss between the cable 4 and electronic components, and extends the camera's service life.

[0050] Obviously, those skilled in the art can make various modifications and variations to this application without departing from the spirit and scope of this application. Therefore, if such modifications and variations fall within the scope of the claims of this application and their equivalents, this application also intends to include such modifications and variations.
