[0063] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Figure 1-Figure 14 The camera assembly 100 according to an embodiment of the present invention includes: a mounting bracket 10 , a driving mechanism 20 and a camera device 30 .

[0064] Specifically, if Figure 1-Figure 14 As shown, one side of the mounting bracket 10 has an opening, the driving mechanism 20 is arranged on the mounting bracket 10, the camera device 30 is connected to the driving mechanism 20, the driving mechanism 20 is suitable for driving the camera device 30 to move between a hidden position and an exposed position, the camera device 30 includes at least one camera 34, when the camera device 30 is located in the hidden position, the camera 34 is hidden in the mounting bracket 10, when the camera device 30 is located in the exposed position, the camera 34 extends from the mounting bracket 10 through the opening to the outside of the mounting bracket 10.

[0065] Combination Figure 1-Figure 6 The mounting bracket 10 forms the basic structure of the camera assembly 100, and is designed with an opening on one side for the extension and retraction of the camera 34. The mounting bracket 10 is suitable for providing physical support for the camera 34. The driving mechanism 20 is responsible for controlling the movement of the camera device 30, and driving the camera device 30 to smoothly and reliably switch between the hidden position and the exposed position. As the core component of the camera assembly 100, the camera device 30 includes at least one camera 34, which can capture video or image data. The camera device 30 can be moved to the exposed position when it is needed, and returned to the hidden position in the mounting bracket 10 when it is not needed.

[0066] According to the camera assembly 100 of the embodiment of the present invention, by integrating the mounting bracket 10, the driving mechanism 20 and the camera device 30, the camera assembly 100 can not only effectively protect the camera device 30 from being easily contaminated by mud or dust, but also can flexibly adjust the shooting state of the camera device 30 according to actual needs, thereby effectively improving the practicality of the camera assembly 100 and helping to improve the structural compactness of the camera assembly 100.

[0067] According to some embodiments of the present invention, Figure 1-Figure 6 As shown, during the movement of the camera device 30 from the hidden position to the exposed position, the camera 34 first extends through the opening to the outside of the mounting bracket 10, and then moves in a direction perpendicular to the central axis of the opening toward a direction away from the central axis.

[0068] That is, the movement path of the camera device 30 is limited. First, the camera device 30 will pass through the opening on the mounting bracket 10 to ensure that the camera 34 can enter the external environment safely and smoothly from the inside of the bracket, that is, the camera device 30 first moves along the first direction A. Then, the movement trajectory of the camera device 30 is carried out along a direction perpendicular to the central axis of the opening, that is, the camera device 30 moves along the second direction B, and the camera device 30 moves toward a position away from the central axis of the bracket so that the camera device 30 is completely located outside the mounting bracket 10 to avoid being blocked.

[0069] Thus, by setting the movement path of the camera device 30, space can be used more effectively, so that the camera 34 can avoid collision with the mounting bracket 10 or other surrounding structures when extended, thereby improving the flexibility and scope of application of the installation. Movement away from the central axis may help the camera device 30 obtain a wider field of view and provide a more ideal shooting effect.

[0070] According to some embodiments of the present invention, Figure 2-Figure 6 As shown, the camera device 30 is rotatably connected to the mounting bracket 10; the driving mechanism 20 includes: a driving device 21, a first connecting rod 22 and a second connecting rod 23, the driving device 21 is arranged on the mounting bracket 10; one end of the first connecting rod 22 is connected to the driving device 21; one end of the second connecting rod 23 is rotatably connected to the other end of the first connecting rod 22, and the other end of the second connecting rod 23 is rotatably connected to the camera device 30.

[0071] The driving device 21 is installed on the mounting bracket 10 as a power source and is responsible for generating the driving force that makes the entire motion system work. One end of the first connecting rod 22 is connected to the driving device 21, and as the first link of the transmission chain, it transmits the power generated by the driving device 21 to the subsequent mechanical structure. One end of the second connecting rod 23 is rotatably connected to the other end of the first connecting rod 22 through a pivot shaft 27. Such a design allows the transmission of force to be accompanied by a change in angle to achieve the rotation of the camera device 30. The other end of the second connecting rod 23 is rotatably connected to the camera device 30 through the pivot shaft 27 to ensure that the camera 34 is stable and accurate when it rotates under force.

[0072] Thus, through the above design, the movement of the driving device 21 is first converted into the reciprocating or rotating movement of the first connecting rod 22, and then the movement is transmitted and converted into the movement of the second connecting rod 23 through the rotatable connection point between the first connecting rod 22 and the second connecting rod 23, and finally the camera device 30 is driven to move along the predetermined trajectory and rotate to the desired position. Such a mechanical linkage mechanism not only ensures the stability and accuracy of the movement of the camera device 30, but also provides a high degree of adjustment freedom and adaptability for the entire assembly, so that the camera assembly 100 can adapt to more variable shooting environments and requirements.

[0073] According to some embodiments of the present invention, Figure 3-Figure 6 As shown, a connecting rod slot 231 is formed on the second connecting rod 23 , and a connecting rod shaft 11 is provided on the mounting bracket 10 , and the connecting rod shaft 11 can be slidably fitted in the connecting rod slot 231 .

[0074] The slide groove on the second connecting rod 23 provides a guide path for the connecting rod shaft 11 on the mounting bracket 10. As a part of the mounting bracket 10, the connecting rod shaft 11 can slide along the slide groove on the second connecting rod 23. The connecting rod slide groove 231 defines the movement trajectory of the camera assembly 100 during the deployment or retraction process, and also ensures the stability and accuracy during the movement process, reducing unnecessary friction and wear.

[0075] Thus, through the sliding cooperation between the connecting rod slot 231 and the connecting rod shaft 11, more precise displacement control can be achieved, so that the entire assembly can reach the preset position more accurately during the movement. Compared with a direct rigid connection, the cooperation between the connecting rod slot 231 and the connecting rod shaft 11 can increase the flexibility between the moving parts while maintaining the structural strength, and reduce the damage caused by external force impact or long-term use. This method also helps to disperse stress, avoid local overload, and extend the overall service life of the camera assembly 100.

[0076] According to some embodiments of the present invention, Figure 3-Figure 6As shown, one end of the connecting rod slot 231 is adjacent to one end of the second connecting rod 23 , and the other end of the connecting rod slot 231 extends obliquely toward the other end of the second connecting rod 23 and along the width direction of the second connecting rod 23 toward the side wall of the mounting bracket 10 .

[0077] One end of the connecting rod slot 231 is adjacent to the end of the second connecting rod 23 connected to the first connecting rod 22, and the other end not only extends along the width direction of the second connecting rod 23, but also extends obliquely toward the side wall of the mounting bracket 10, and the connecting rod slot 231 is formed into a structure with a certain curvature. The connecting rod shaft 11 of the mounting bracket 10 is fitted in the connecting rod slot 231. When the second connecting rod 23 moves driven by the first connecting rod 22, the connecting rod slot 231 moves relative to the connecting rod shaft 11. The structure of the connecting rod slot 231 defines the movement path of the second connecting rod 23 relative to the mounting bracket 10, and further defines the movement path of the second connecting rod 23 driving the camera device 30.

[0078] Therefore, the structural setting of the connecting rod slot 231 is suitable for guiding the movement path of the camera device 30. Through the inclined layout of the connecting rod slot 231, even when the installation space is limited, it can ensure that the camera assembly 100 has a sufficient range of motion without increasing the volume of the overall device, which helps to make the structure of the camera assembly 100 compact. The inclined slot design also helps to distribute force during the driving process, reduce jamming or resistance, and make the entire movement process smoother. When the camera device 30 is deployed outward, the inclined slot can naturally guide it to move along the most efficient path, reduce unnecessary friction and force loss, and improve energy efficiency. The inclined extended slot helps to maintain a certain self-stabilizing state when the camera device 30 moves, prevent excessive swinging or accidental derailment, and enhance the stability of the camera device 30 in various positions.

[0079] According to some embodiments of the present invention, Figure 6 As shown, the second connecting rod 23 has a connecting rod limiting surface 232; when the camera device 30 is located at the exposed position, the connecting rod limiting surface 232 abuts against the side wall of the mounting bracket 10 to keep the camera device 30 at the exposed position.

[0080] The connecting rod limiting surface 232 is located at the other end of the connecting rod slot 231. When the camera device 30 is fixed to the exposed position, the connecting rod limiting surface 232 is suitable for abutting against the inner wall of one side of the mounting bracket 10 along the width direction. The side wall of the mounting bracket 10 can form a physical barrier to the camera 34 in the width direction to limit the camera device 30 and prevent the camera device 30 from continuing to rotate.

[0081] Thus, when the camera device 30 moves to the exposed position, the contact between the connecting rod limit surface 232 and the side wall of the mounting bracket 10 ensures that the camera device 30 will not retract due to slight external force or the device's own gravity and other factors, and remains in the preset exposed position, which is conducive to ensuring the position stability of the camera device 30. The limit design between the second connecting rod 23 and the mounting bracket 10 can also reduce direct impact through the support of the side wall when the camera device 30 is accidentally hit, protect the camera device 30 from damage, and reduce the stress on the entire mechanical structure, thereby extending the service life of the component. The structure of the connecting rod limit surface 232 is simple, which is conducive to simplifying the structural design of the camera assembly 100 and improving the overall practicality and durability of the camera assembly 100.

[0082] According to some embodiments of the present invention, Figure 4 As shown, the camera device 30 has a camera device limiting surface 31; when the camera device 30 is located in the hidden position, the camera device limiting surface 31 abuts against the inner wall of the mounting bracket 10 opposite to the opening to keep the camera device 30 in the hidden position.

[0083] The camera 34 of the camera device 30 has a limiting surface arranged on the upper side of the camera device 30 in the height direction. The camera device limiting surface 31 is suitable for contacting and abutting against the inner wall of the mounting bracket 10 opposite to the opening in the height direction. The camera device 30 is completely located inside the mounting bracket 10 .

[0084] Therefore, the cooperation between the camera device limit surface 31 and the inner wall of the mounting bracket 10 opposite to the opening can ensure that the camera 34 is firmly maintained inside the mounting bracket 10 when not in use, avoiding accidental exposure due to vibration or accidental touch, thereby protecting the camera device 30 and maintaining the overall concealment of the device.

[0085] According to some embodiments of the present invention, Figure 7 As shown, the driving device 21 includes: a driving installation box 24, a motor 25 and a transmission mechanism 26. The driving installation box 24 is arranged on the mounting bracket 10, the motor 25 is arranged in the driving installation box 24, and the transmission mechanism 26 is connected between the motor 25 and one end of the first connecting rod 22.

[0086] The drive installation box 24 is a carrier of the motor 25 and other drive components. The drive installation box 24 is fixed on the mounting bracket 10, and plays a role in protecting and integrating the drive device 21. The motor 25 is installed inside the drive installation box 24, and is the power source of the entire drive device 21. It is responsible for converting electrical energy into mechanical energy and driving the transmission mechanism 26 to work. The transmission mechanism 26 connects the motor 25 and one end of the first connecting rod 22. The transmission mechanism 26 is suitable for energy transmission and motion conversion, ensuring that the rotational motion of the motor 25 is efficiently and accurately converted into the linear or rotational motion of the connecting rod.

[0087] Therefore, the driving device 21 integrates the motor 25 and other components into the driving mounting box 24, effectively utilizing the internal space of the mounting bracket 10, maintaining the neat appearance of the component and the compactness of the overall design, and the design of the transmission mechanism 26 can ensure that the rotational motion of the motor 25 is accurately transmitted to the first connecting rod 22, thereby realizing precise control of the movement of the camera device 30, whether it is telescopic or rotational action, the expected effect can be achieved, and flexible motion control of the camera device 30 can be realized.

[0088] According to some embodiments of the present invention, Figure 7 As shown, the drive mounting box 24 includes: a drive mounting bracket 241 and a drive mounting shell 242. The drive mounting bracket 241 is arranged on the mounting bracket 10, and the motor 25 is installed on the drive mounting bracket 241. The drive mounting shell 242 is connected to the side of the drive mounting bracket 241 away from the first connecting rod 22. The drive mounting shell 242 and the drive mounting bracket 241 jointly define an accommodating cavity 243, and the motor 25 and the transmission mechanism 26 are both arranged in the accommodating cavity 243.

[0089] The drive mounting bracket 241 is directly mounted on the mounting bracket 10 to provide a stable mounting platform for the motor 25, and the drive mounting housing 242 is connected to the side of the drive mounting bracket 241 away from the first connecting rod 22. The drive mounting bracket 241 and the drive mounting housing 242 cooperate with each other through a specific structural design to jointly define an accommodating cavity 243. The setting of the accommodating cavity 243 provides a closed and protected installation environment for the motor 25 and the transmission mechanism 26.

[0090] Thus, by integrating the motor 25 and the transmission mechanism 26 in the accommodating chamber 243 defined by the drive mounting bracket 241 and the drive mounting housing 242, a high degree of integration of the components is achieved, the various components of the drive device 21 are integrated, and the space is effectively utilized. The provision of the accommodating chamber 243 helps prevent external dust, moisture, etc. from damaging the motor 25 and the transmission mechanism 26, and can also reduce noise leakage, thereby improving the quietness of the operation of the entire system.

[0091] According to some embodiments of the present invention, Figure 7 As shown, a sealing gasket 244 is provided between the drive mounting bracket 241 and the drive mounting housing 242 .

[0092] The setting of the sealing gasket 244 ensures the close fit between the drive mounting bracket 241 and the drive mounting shell 242, effectively preventing external environmental factors such as dust and water vapor from invading the accommodating chamber 243, protecting precision components such as the motor 25 and the transmission mechanism 26 from pollution and corrosion, and extending the service life of the camera assembly 100. In addition to having a physical isolation effect, the sealing gasket 244 can also have a certain sound insulation effect, by absorbing and blocking the vibration and noise generated by mechanical movement, reducing the sound generated by the entire camera assembly 100 during operation. The elastic properties of the sealing gasket 244 can absorb the tiny assembly tolerance between the mounting bracket 10 and the shell, reduce the internal looseness caused by loose assembly or slight deformation, thereby improving the overall stability of the camera assembly 100 and the smoothness of movement.

[0093] According to some embodiments of the present invention, Figure 7 As shown, the transmission mechanism 26 includes: a first worm 261, a first gear worm 262 and a second transmission shaft 263. The first worm 261 is connected to the motor 25. The first gear worm 262 includes a first transmission shaft 2621, a first gear 2622 and a second worm 2623. The first gear 2622 and the second worm 2623 are both arranged on the first transmission shaft 2621. The first gear 2622 is meshed with the first worm 261. The second transmission shaft 263 is provided with a second gear 2631. The second gear 2631 is meshed with the second worm 2623. The second transmission shaft 263 is drivingly connected to one end of the first connecting rod 22.

[0094] The first worm 261 is directly connected to the motor 25, and the rotational motion of the motor 25 is converted into a rotational torque through the first worm 261. The first gear worm 262 is a composite structure, integrating a first transmission shaft 2621, a first gear 2622, and a second worm 2623. Among them, the first transmission shaft 2621 serves as a basic support structure, and the first gear 2622 is installed on this shaft and meshes with the first worm 261, thereby receiving the rotational power transmitted from the motor 25 through the first worm 261. The second worm 2623 is arranged on the first transmission shaft 2621, but is coaxial with the first gear 2622 but relatively independent. The second transmission shaft 263 is drivingly connected to one end of the first connecting rod 22, and is used to finally transmit the rotational power to the first connecting rod 22. The second transmission shaft 263 is equipped with a second gear 2631, and the second gear 2631 meshes with the second worm 2623 in the first gear worm 262, forming a secondary transmission link, further adjusting or amplifying the transmission of the rotational motion.

[0095] The working process of the entire transmission mechanism 26 is as follows:

[0096] The motor 25 starts to rotate, and the rotational motion is converted into a rotational torque through the directly connected first worm 261. The rotation of the first worm 261 drives the first gear 2622 on the first gear worm 262 to achieve the initial power transmission. The second worm 2623 in the first gear worm 262 rotates coaxially with the first gear 2622, but through the special tooth shape of the worm and worm wheel, the rotational motion is transmitted to the second gear 2631 on the second transmission shaft 263 at a higher reduction ratio (or speed increase ratio, depending on the design). The meshing of the second gear 2631 and the second worm 2623 transmits the converted power to the second transmission shaft 263, and then the second transmission shaft 263 drives the first connecting rod 22, thereby pushing the camera device 30 to complete the required telescopic or rotational action.

[0097] Therefore, the transmission mechanism 26 has a high-precision and high-stability transmission mechanism, which can achieve high torque output. The worm gear transmission can achieve a large reduction ratio due to its special tooth shape, and can generate a large driving force even if the output speed of the motor 25 is not high. The high precision and stability of the gear transmission make the motion control of the camera assembly 100 more precise, and the transmission mechanism 26 can better withstand external force impact and long-term operation, thereby improving the durability and reliability of the camera assembly 100.

[0098] According to some embodiments of the present invention, Figure 7 As shown, a first mounting opening 333 is formed on a side of the drive mounting bracket 241 away from the drive mounting shell 242, and the second transmission shaft 263 is installed in the accommodating cavity 243 through the first mounting opening 333; the drive mounting box 24 further includes: a first side cover 245, the first side cover 245 is arranged at the first mounting opening 333, and a first sealing ring 246 is arranged between the first side cover 245 and the drive mounting bracket 241.

[0099] The design of the first installation port 333 is to facilitate the installation and maintenance of the second transmission shaft 263. Through the first installation port 333, the second transmission shaft 263 can be directly inserted into the interior of the accommodating chamber 243 and connected to other components of the transmission mechanism 26, which not only ensures the convenience of assembly, but also facilitates accessibility during later maintenance. The first side cover 245 can ensure the sealing of the accommodating chamber 243, and the first side cover 245 is equipped at the first installation port 333. The first side cover 245 is installed at the first installation port 333. After closing, it can effectively prevent external factors such as dust and moisture from invading the internal space, protect the transmission mechanism 26 from environmental influences, and also enhance the structural integrity of the entire assembly. A first sealing ring 246 is also provided between the first side cover 245 and the drive mounting bracket 241. As an important sealing element, the first sealing ring 246, through its elasticity and compressibility, closely fits the contact surface of the first side cover 245 and the mounting bracket 10, further strengthens the sealing effect of the installation port, effectively prevents the penetration of external pollutants, and also improves the waterproof and dustproof level of the transmission mechanism 26.

[0100] Therefore, the setting of the driving device 21 can optimize the structural layout of the camera assembly 100 and facilitate the installation and maintenance of the transmission shaft. More importantly, through the cooperation of the first side cover 245 and the first sealing ring 246, the cleanliness and dryness of the inside of the driving system are ensured, thereby improving the stability and weather resistance of the entire camera assembly 100, extending its service life and reducing maintenance costs.

[0101] According to some embodiments of the present invention, Figure 7 As shown, a second sealing ring 2632 is sleeved on the second transmission shaft 263 , and the second sealing ring 2632 is sealed between the second gear 2631 and the first side cover 245 .

[0102] The second sealing ring 2632 closely fits the contact interface between the second gear 2631 and the first side cover 245 through its own elasticity and compressibility, and can maintain a good sealing state even in the case of slight vibration caused by the rotation of the transmission shaft and the meshing of the gears, effectively preventing pollutants from entering the interior of the driving device 21 through the gear gap. By adding the second sealing ring 2632 to the second transmission shaft 263, the protection level of the entire transmission mechanism 26 can be significantly improved, especially for the precise gear structure, which can avoid the wear or jamming caused by the entry of foreign matter, and ensure the transmission efficiency and the long-term stable operation of the components.

[0103] Therefore, the design of the second sealing ring 2632 further strengthens the sealing of the internal transmission mechanism 26 of the camera assembly 100, ensuring that the driving device 21 can still maintain high-performance operation under complex and changeable usage environments, thereby improving the overall reliability and service life of the camera assembly 100.

[0104] According to some embodiments of the present invention, Figure 7 As shown, a second mounting opening 334 is formed on the drive mounting bracket 241, and the first gear worm 262 is installed in the accommodating cavity 243 through the second mounting opening 334; the drive mounting box 24 further includes: a second side cover 247, the second side cover 247 is arranged at the second mounting opening 334, and a third sealing ring 248 is provided between the second side cover 247 and the drive mounting bracket 241.

[0105] The second mounting opening 334 is provided on the drive mounting bracket 241, which is convenient for the installation and later maintenance of the first gear worm 262. The first gear worm 262 can be smoothly placed in the accommodating cavity 243 and docked with other components of the transmission mechanism 26, ensuring the convenience of assembly and convenience during maintenance. The second side cover 247 is configured at the second mounting opening 334, and its function is to close and seal the second mounting opening 334 to prevent external impurities and liquids from invading the interior of the drive mounting box 24. The installation of the second side cover 247 not only maintains the cleanliness of the interior, but also helps to improve the firmness of the overall structure of the drive device 21. A third sealing ring 248 is also embedded between the second side cover 247 and the drive mounting bracket 241. The third sealing ring 248 uses its own elasticity and pressure to fit tightly on the contact surface between the second side cover 247 and the mounting bracket 10, further strengthening the sealing effect, and effectively preventing dust, moisture or other harmful substances from entering through the second mounting opening 334, which is crucial for improving the environmental adaptability and long-term stability of the camera assembly 100.

[0106] Therefore, the provision of the second mounting port 334, the second side cover 247 and the third sealing ring 248 makes the installation and maintenance of the first gear worm 262 easier, and also ensures the cleanliness and dryness of the inside of the driving device 21, providing a strong guarantee for the stable operation of the camera assembly 100 in various harsh environments.

[0107] According to some embodiments of the present invention, Figure 7 As shown, the transmission mechanism 26 is a two-stage worm helical gear transmission mechanism 26 .

[0108] By adopting a two-stage worm helical gear transmission, the transmission system of the camera assembly 100 can achieve more efficient torque conversion and motion transmission. The first-stage worm gear transmission converts the rotational motion of the motor 25 into a low-speed, high-torque output of the worm gear, and the second-stage worm helical gear transmission further transmits and may change the direction or ratio of this motion to adapt to the specific motion requirements of the camera device 30 (such as linear push-pull or rotation). The combination of the worm and the helical gear can provide better tooth surface contact and self-locking performance compared to the straight tooth transmission. The tooth surface of the helical gear is inclined at a certain angle, which can not only improve the stability during the meshing process and reduce noise, but also improve the transmission efficiency to a certain extent, especially in occasions where the load changes greatly or high-precision transmission is required. The worm helical gear transmission mechanism 26 is suitable for the camera assembly 100 with limited space due to its small size and large transmission ratio. The two-stage transmission design can achieve the required motion conversion in a small installation space, which helps to maintain the compactness and lightweight of the entire camera assembly 100. Due to its self-locking property, the worm helical gear transmission can effectively prevent reversal caused by external force, thereby increasing the stability of the system. At the same time, the contact method of the helical gears can disperse the load and reduce wear, thereby extending the service life of the components. The fine adjustment capability of the two-stage transmission makes the movement of the camera 34 more precise and controllable. Whether it is fast response or fine adjustment of the angle, it can be achieved through precise transmission ratio design.

[0109] Therefore, the camera assembly 100 using the two-stage worm helical gear transmission mechanism 26 achieves precise control of movement, compact design of the system, and improves the overall stability and durability of the camera assembly 100 while ensuring efficient power transmission.

[0110] According to some embodiments of the present invention, Figure 8-Figure 11 As shown, the camera device 30 includes: a camera housing 32 and a camera slide rail 33, the camera housing 32 is rotatably connected to the other end of the second connecting rod 23, the camera 34 is arranged in the camera housing 32, the camera housing 32 is slidably matched with the camera slide rail 33, and the camera slide rail 33 is rotatably connected to the mounting bracket 10.

[0111] Through the rotatable connection between the camera housing 32 and the other end of the second connecting rod 23, the camera device 30 can be rotated around the connecting axis between the camera housing 32 and the second connecting rod 23 to adjust the angle of the camera device 30. The camera slide 33 extends in a straight line, and the camera housing 32 can move relative to the camera slide 33 along the extension direction of the camera slide 33, so that the camera device 30 can move between the hidden position and the exposed position, further expanding the range of motion of the camera device 30. The camera slide 33 is rotatably connected to the lower end of the mounting bracket 10 in the height direction through the pivot shaft 27. When the camera device 30 rotates driven by the second connecting rod 23, the camera slide 33 rotates relative to the mounting bracket 10 as the camera 34 rotates.

[0112] Therefore, by integrating the combination of the camera housing 32 and the camera slide rail 33 in the camera device 30, and realizing their rotatable and sliding connection with the second connecting rod 23 and the mounting bracket 10, the camera assembly 100 not only ensures the smooth transition of the camera device 30 between the hidden position and the exposed position, but also greatly enhances the positioning and viewing angle adjustment capabilities of the camera 34, adapts to the complex and changeable shooting environment requirements, and improves shooting efficiency and user experience.

[0113] According to some embodiments of the present invention, Fig.10 and Fig.11 As shown, a first slide groove 331 and a second slide groove 332 are formed on the camera slide rail 33, and the first slide groove 331 and the second slide groove 332 are respectively located on both sides of the camera housing 32; a plurality of first matching columns 321 and a plurality of second matching columns 322 are provided on the camera housing 32, and the plurality of first matching columns 321 can be slidably fitted in the first slide groove 331, and the plurality of second matching columns 322 can be slidably fitted in the second slide groove 332.

[0114] The camera housing 32 has a length direction, and the first slide groove 331 and the second slide groove 332 are respectively located on both sides of the length direction of the camera housing 32, and the first slide groove 331 and the second slide groove 332 are arranged opposite to each other along the length direction of the camera housing 32. A plurality of first matching columns 321 and a second matching column 322 are respectively formed on the two side surfaces of the camera housing 32 along the length direction, and one end of the first matching column 321 and the second matching column 322 are connected to one side surface of the camera housing 32 along the length direction, and the other ends of the first matching column 321 and the second matching column 322 extend in a direction away from the camera housing 32. The plurality of first matching columns 321 are correspondingly matched with the first slide groove 331 to form a slidable matching relationship.

[0115] Thus, the first slide groove 331 and the second slide groove 332 are respectively located on both sides of the camera housing 32, which can provide a more stable sliding support for the camera housing 32, and also enable the camera housing 32 to maintain better balance and stability when sliding, reducing the shaking or offset that may be caused by single-point support. The design of multiple first matching columns 321 and multiple second matching columns 322 increases the stability of sliding, and also ensures that during the sliding process, the connection between the camera housing 32 and the slide rail is more secure, not easy to derail or misalign, and improves the mechanical stability of the entire system.

[0116] According to some embodiments of the present invention, Fig.10 and Fig.11 As shown, the camera housing 32 includes: a camera bracket 323, a camera bracket cover 324, a first camera bracket side cover 325 and a second camera bracket side cover 326, a plurality of first positioning columns 327 and a plurality of second positioning columns are respectively provided on both sides of the camera bracket 323, the camera bracket cover 324 is arranged on one side of the camera bracket 323 adjacent to the camera slide rail 33, the camera bracket cover 324 and the camera bracket 323 jointly define a camera 34 installation cavity, and the camera 34 is arranged in the camera 34 installation cavity; the first camera bracket side cover 325 and the second camera bracket side cover 326 are respectively arranged on both sides of the camera bracket 323, a plurality of first matching columns 321 are provided on the first camera bracket side cover 325, and the plurality of first matching columns 321 pass through the first slide groove 331 and respectively match with the plurality of first positioning columns 327, and a plurality of second matching columns 322 are provided on the second camera bracket side cover 326, and the plurality of second matching columns 322 pass through the second slide groove 332 and respectively match with the plurality of second positioning columns.

[0117] The camera bracket 323 is a bearing core, and a plurality of first positioning columns 327 and a second positioning column are respectively arranged on both sides of the camera bracket 323. The first positioning columns 327 and the second positioning columns are respectively arranged at both ends of the camera bracket 323 along the length direction. The first positioning columns 327 and the second positioning columns are suitable for cooperating with the slide rail to ensure the accurate sliding and positioning of the camera housing 32 on the slide rail. The camera bracket cover 324 is arranged on one side of the camera bracket 323 along the width direction. The camera bracket cover 324 and the camera bracket 323 define a camera 34 installation cavity that facilitates the assembly of the camera 34. The first camera bracket side cover 325 and the second camera bracket side cover 326 are respectively arranged on both sides of the camera bracket 323 along the length direction. The first slide groove 331 is arranged between one end of the camera bracket 323 along the length direction and the first camera bracket side cover 325. The plurality of first matching columns 321 correspond to the plurality of first positioning columns 327 one by one. The first matching column 321 is inserted into the first positioning column 327 and movably matched in the first slide groove 331. Similarly, the second slide groove 332 is arranged between one end of the camera bracket 323 along the length direction and the second camera bracket side cover 326, and the multiple second matching columns 322 correspond one by one to the multiple second positioning columns. The second matching columns 322 are inserted into the second positioning columns and can be movably matched in the second slide groove 332.

[0118] Thus, the camera 34 installation cavity provides a safe and stable installation environment for the camera 34, and also facilitates the installation and fixation of the camera 34, as well as subsequent maintenance and replacement. The first camera bracket side cover 325 and the second camera bracket side cover 326 further enhance the stability and sealing of the structure, and are respectively installed on both sides of the camera bracket 323, increasing the stability and protection of the assembly. The design of multiple mounting columns and matching columns passing through the slide groove ensures accurate guidance during the movement of the camera device 30, improves the structural compactness and stability of the entire camera device 30, and enhances the protection of the camera 34.

[0119] According to some embodiments of the present invention, Fig.10 and 11 As shown, a first mounting opening 333 is provided on a side of the first slide groove 331 adjacent to the camera housing 32, and a second mounting opening 334 is provided on a side of the second slide groove 332 adjacent to the camera housing 32; a plurality of first positioning columns 327 pass through the first mounting opening 333 to be engaged in the first slide groove 331, and a plurality of second positioning columns pass through the second mounting opening 334 to be engaged in the second slide groove 332.

[0120] The first slide groove 331 and the second slide groove 332 both extend along the width direction of the camera housing 32. The first slide groove 331 is provided with a first mounting opening 333 at one end adjacent to the camera housing 32 along the extending direction. The first mounting opening 333 passes through the end of the first slide groove 331 along the extending direction of the first slide groove 331. The second slide groove 332 is provided with a second mounting opening 334 at one end adjacent to the camera housing 32 along the extending direction. The second mounting opening 334 passes through the end of the second slide groove 332 along the extending direction of the first slide groove 331.

[0121] Thus, the first mounting opening 333 and the second mounting opening 334 serve as precise interfaces. Through the first mounting opening 333, the plurality of first positioning posts 327 can accurately pass through and fit tightly in the first slide groove 331. Similarly, the second mounting opening 334 allows the plurality of second positioning posts to perfectly dock with the corresponding positions in the second slide groove 332. This design ensures the stable sliding of the camera housing 32 on the slide rail, and is also convenient for installation and adjustment. Each positioning post is accurately embedded in its corresponding slide groove, reducing errors and complexity during installation. Through the design of the first mounting opening 333 and the second mounting opening 334, not only the smooth movement of the sliding mechanism is ensured, but also the structural stability and durability of the entire camera assembly 100 are enhanced.

[0122] According to some embodiments of the present invention, Fig.10 As shown, at least one lens hole is formed on the camera bracket 323; the camera 34 has a lens, and the lens is matched at the lens hole. The camera bracket 323 has a lens hole formed on a side wall away from the camera bracket cover 324 along the width direction. The camera 34 in the camera assembly 100 is equipped with a lens, which is accurately installed and matched in the lens hole on the camera bracket 323 to ensure that the lens can be firmly fixed in a predetermined position.

[0123] Therefore, the design of the lens hole not only provides a mounting position for the lens, but also protects the lens from direct impact or scratching from the outside to a certain extent, thereby increasing the physical protection of the camera assembly 100. At the same time, by fixing the lens with a bracket, the image jitter caused by vibration during shooting can be effectively reduced, the clarity and stability during shooting can be improved, and the lens can be stably installed, effectively protected, and conveniently maintained.

[0124] According to some embodiments of the present invention, Fig.10 As shown, a plurality of cameras 34 are arranged in the camera 34 installation cavity, and the plurality of cameras 34 work independently.

[0125] Multiple cameras 34 are arranged in sequence in the camera 34 installation cavity along the length direction of the camera bracket 323, which can achieve multi-angle and all-round coverage of the shooting area, reduce blind spots, and improve the comprehensiveness and accuracy of shooting. Each camera 34 can capture images from different directions, providing richer visual data for applications such as security monitoring and intelligent analysis. Multiple cameras 34 work independently, and each camera 34 can perform image acquisition, processing and transmission independently without interfering with each other, thereby improving the work efficiency and flexibility of the system. In actual applications, even if a camera 34 fails, it will not affect the normal operation of other cameras 34, thereby enhancing the reliability of the system.

[0126] Therefore, by integrating multiple independently working cameras 34 into the camera assembly 100, not only the shooting range and efficiency can be significantly enhanced, but also a high degree of flexibility and scalability can be provided, effectively improving the practicality of the camera assembly 100.

[0127] According to some embodiments of the present invention, Fig.11 As shown, a seal 35 is provided between the camera slide rail 33 and the camera housing 32 .

[0128] The seal 35 is provided to reduce the vibration and noise generated when the camera 34 moves on the slide rail, improve the shooting stability, and ensure that the video picture is clear and smooth. As a protective layer, the seal 35 increases the camera assembly 100's ability to resist external physical impacts, whether it is an accidental collision or daily wear and tear, and can provide additional safety protection for the camera 34, making the entire camera assembly 100 more durable. Therefore, the setting of the seal 35 can improve the environmental adaptability and long-term operation reliability of the camera assembly 100.

[0129] According to some embodiments of the present invention, Fig.11 As shown, the sealing member 35 is a soft rubber member.

[0130] Because of its softness and elasticity, the soft rubber part can fit tightly into the gap between the camera slide rail 33 and the shell, forming an effective sealing barrier to prevent the penetration of fine particles and liquids, and further enhance the waterproof and dustproof capabilities. Soft rubber parts usually have excellent high and low temperature resistance, and can maintain their physical properties without deformation, hardening or cracking under a wide range of climatic conditions, ensuring the stable working performance of the camera assembly 100 in different environments. Soft rubber parts have good vibration absorption properties and can absorb the vibration and operating noise generated when the camera 34 slides. Soft rubber parts are usually easy to process and install, and can be designed into a shape that is easy to assemble, which simplifies the assembly process of the camera assembly 100 and also facilitates subsequent maintenance and replacement.

[0131] Specifically, combined Figure 4-Figure 5, the movement process of the camera assembly 100 is as follows:

[0132] When the camera device 30 moves from the hidden position to the exposed position, the driving device 21 drives one end of the first connecting rod 22 to rotate, thereby driving the other end of the first connecting rod 22 to rotate downward in the height direction, thereby driving the second connecting rod 23 to move downward, and the connecting rod slide groove 231 on the second connecting rod 23 moves relative to the connecting rod shaft 11 of the mounting bracket 10 to guide the movement path of the second connecting rod 23, and the other end of the second connecting rod 23 drives the camera device 30 to move downward in the height direction, so that the camera device 30 extends from the opening of the mounting bracket 10, and the second connecting rod 23 drives the camera device 30 to move outside the mounting bracket 10 in the width direction of the mounting bracket 10 in a direction away from the central axis of the mounting bracket 10. In this process, the camera housing 32 moves relative to the camera slide rail 33, and along the extension direction of the slide groove, the second connecting rod 23 drives the camera 34 to move outside the mounting bracket 10 in a direction away from the central axis of the mounting bracket 10 until the camera device 30 moves to the exposed position.

[0133] When the camera device 30 moves from the exposed position to the hidden position, the driving device 21 drives the first connecting rod 22 to rotate in the opposite direction, drives the second connecting rod 23 to move in the opposite direction, and then drives the camera housing 32 to move first along the extension direction of the slide groove toward the direction of the central axis of the mounting bracket 10, and then moves upward in the height direction to completely enter the interior of the mounting bracket 10, so that the camera device 30 returns to the hidden position.

[0134] According to some embodiments of the present invention, Figure 1-Figure 3 As shown, it further includes: a cleaning device 40, which is arranged on the mounting bracket 10, and the cleaning device 40 is used to clean the camera 34. When the camera device 30 returns to the hidden position, the cleaning component can clean the camera 34, and the cleaning device 40 can automatically perform the cleaning task on the camera 34. Therefore, the setting of the cleaning device 40 improves the maintenance efficiency of the camera assembly 100, ensures the convenience and stability of the camera 34 cleaning process, and regularly cleans the camera 34 to effectively prevent the dust, water droplets or other stains accumulated on the lens from affecting the quality of the captured image, prolong the service life of the camera 34, and at the same time reduce the phenomenon of unclear shooting due to dirty lens, and improve the reliability and accuracy of the camera assembly 100.

[0135] According to some embodiments of the present invention, Figure 1-Figure 4 , Fig.12 and Fig.13 As shown, the cleaning device 40 includes: a nozzle structure 41, which is arranged on the mounting bracket 10, and is formed with a liquid inlet hole 42 and at least one spray hole 43. When the camera device 30 is located in the hidden position, the spray hole 43 is opposite to the camera 34.

[0136] The nozzle structure 41 is provided with a liquid inlet hole 42 for receiving a cleaning liquid (such as clean water or a special cleaning agent). At least one spray hole 43 is formed on the nozzle structure 41. When the camera 34 is in a hidden position, the spray hole 43 faces the camera 34, ensuring that the cleaning liquid can be directly and accurately sprayed onto the surface of the camera 34 to clean the surface of the camera 34.

[0137] Therefore, the design of the nozzle structure 41 can realize the self-cleaning function of the camera assembly 100. Regular and effective cleaning can effectively remove dust, stains and water droplets on the lens, ensure the clarity of the image of the camera 34, improve the overall efficiency of the camera assembly 100, and greatly improve the convenience of maintenance of the camera 34.

[0138] According to some embodiments of the present invention, Figure 1-Figure 4 , Fig.12 and Fig.13 As shown, the cleaning device 40 further includes: a liquid tank 44 and a liquid pump 45 . The liquid tank 44 is disposed on the mounting bracket 10 , the liquid pump 45 is disposed on the liquid tank 44 , and the liquid inlet 42 is connected to the liquid tank 44 through the liquid pump 45 .

[0139] The liquid tank 44 is arranged on the mounting bracket 10 and is used to store cleaning liquid (such as clean water or special cleaning agent). The design of the liquid tank 44 enables the cleaning device 40 to have an independent cleaning liquid supply capability, without frequent external refilling, thereby improving the autonomy and continuity of the cleaning operation. The liquid pump 45 is installed on the liquid tank 44. The liquid pump 45 can extract the cleaning liquid in the liquid tank 44 and transport it to the liquid inlet 42 of the nozzle structure 41 through a pipeline, so that the cleaning liquid can clean the surface of the camera 34. The existence of the liquid pump 45 enables the supply of the cleaning liquid to be precisely controlled as required, and both the flow rate and the pressure can be adjusted to adapt to different cleaning requirements and environmental conditions. Through the connection between the liquid pump 45 and the liquid inlet 42, a closed-loop automatic liquid supply system is formed. When the cleaning program is started, the liquid pump 45 will automatically extract the cleaning liquid in the liquid tank 44, transport it to the nozzle structure 41 through a pipeline, and then spray it onto the surface of the camera 34 through the spray hole 43 to complete the cleaning task. This process has a high degree of automation, reduces human intervention, and improves efficiency.

[0140] Therefore, the cleaning device 40, through the integration of the liquid tank 44 and the liquid pump 45, can not only realize the automatic supply and precise spraying of the cleaning liquid, but also greatly improve the self-maintenance capability of the camera assembly 100, ensure the long-term stable operation of the cleaning system, and ensure the continuous and efficient operation of the camera assembly 100.

[0141] According to some embodiments of the present invention, Fig.12As shown, the cleaning device 40 includes: a cleaning member 46, which is arranged in the mounting bracket 10, and the cleaning member 46 cleans the camera 34 when the camera device 30 moves.
