[0001] This application claims priority to a Chinese patent application filed with the Patent Office of China on January 19, 2024, with application number 202410083526.4 and application name “A camera assembly and mobile terminal device conveniently installed on a glass curtain wall”, the entire contents of which are incorporated herein by reference. Technical Field

[0002] The present application relates to the field of photography, and in particular to a camera assembly and a mobile terminal device. Background Art

[0003] Cameras, as monitoring devices, are widely used across various industries. Cameras mounted on building glass curtain walls can monitor the building's surroundings, offering a wide viewing angle and recording any urban activity. In the event of an accident or security incident near a building, cameras can capture video of the incident. However, existing cameras mounted on building glass curtain walls lack adjustable viewing angles, making them inconvenient to use. Summary of the Invention

[0004] The purpose of this application is to address the problems existing in the background technology and propose a camera component and a mobile terminal device that can solve the above technical problems.

[0005] In a first aspect, the present application provides a camera assembly, comprising:

[0010] A suction cup adsorption type lifting mechanism, wherein the suction cup adsorption type lifting mechanism is arranged on the frame; and

[0011] A servo motor is provided on the frame and is used to drive the suction cup adsorption lifting mechanism to move, so as to achieve rolling adsorption of the glass curtain wall;

[0012] Wherein, the suction cup adsorption type lifting mechanism includes multiple suction cups and multiple sets of air extraction components;

[0013] The plurality of groups of air extraction components correspond to and are in communication with the plurality of suction cups, and the plurality of groups of air extraction components are respectively connected to the guide rings;

[0014] Specifically, when the exhaust assembly is located at the first position of the guide ring, the exhaust assembly increases the adsorption pressure between the suction cup and the glass curtain wall, and the suction cup is adsorbed on the glass curtain wall; when the exhaust assembly is located at the second position of the guide ring, the exhaust assembly reduces the adsorption pressure between the suction cup and the glass curtain wall, and the suction cup is separated from the glass curtain wall.

[0015] Therefore, in this application, the camera assembly is adsorbed or separated from the glass curtain wall through the mechanical cooperation of the exhaust assembly and the guide ring, so as to realize rolling adsorption of the glass curtain wall, and then the shooting angle of the camera module is changed by changing the installation position of the camera assembly, which simplifies the adsorption and separation structure between the camera assembly and the glass curtain wall and eliminates the need for electrical control.

[0016] In a second aspect, the present application provides a camera assembly, comprising:

[0017] frame;

[0018] A camera module, the camera module comprising a first camera and two second cameras symmetrically distributed on both sides of the first camera, wherein the first camera is connected to the frame;

[0019] An orientation control mechanism includes a left-right adjustment component connected between the two second cameras and the frame, and the left-right adjustment component adjusts the angle of the two second cameras relative to the first camera.

[0020] Therefore, in the present application, the angles of the two second cameras relative to the first camera can be adjusted by the left and right adjustment components of the orientation control mechanism, thereby changing the shooting viewing angle of the camera module of the camera assembly.

[0021] In a third aspect, the present application proposes a mobile terminal device, including a camera assembly, the mobile terminal device also including a signal transmitter and a remote controller, the remote controller being communicatively connected to the signal transmitter,

For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two elements or interaction between two elements.

[0036] Next, the structure of the mobile terminal device 1000 in an embodiment of the present application will be described with reference to FIG. 1 to FIG. 7 .

[0037] As shown in FIG1 , the mobile terminal device 1000 includes a camera assembly 100 , a signal transmitter 200 and a remote controller 300 . The remote controller 300 is communicatively connected to the signal transmitter 200 , and the signal transmitter 200 is electrically connected to the camera assembly 100 .

[0038] Thus, a remote control signal can be sent through the remote controller 300 , and the remote control signal is transmitted to the camera assembly 100 through the signal transmitter 200 for controlling the camera assembly 100 .

[0039] The camera assembly 100 includes a camera module 22 , a video image communication transmission module 29 , a storage module 30 and a height and orientation control module 31 .

[0040] The camera module 22 includes a standard frame recording module 32, a skip frame recording module 33, a frame connection module 34, a continuous frame regeneration module 35, and a video output module 36. The video output module 36 is configured to record real images at a preset standard frame rate of M frames / s during a portion of a preset time period. The skip frame recording module 33 is configured to extract N frames per second from M frames at the M frame rate and record real images at the N frame rate / s during the remaining time periods of the preset time period. The frame connection module 34 is configured to communicate with the standard frame recording module 32 and the skip frame recording module 33 and to overlap the frame at the end of any unit time in the preset time period with the frame at the beginning of the next adjacent unit time. The continuous frame regeneration module 35 is configured to communicate with the frame connection module 34 and to retain one of the overlapping frames in the preset time period to regenerate a continuous frame video. The video output module 36 is configured to communicate with the continuous frame regeneration module 35 and output the video data within the preset time period. Wherein, M and N are both positive integers, and N<M. The necessity of video images captured by the skip frame recording module 33 at a frame rate of N frames / s is lower than the necessity of video images captured by the standard frame recording module 32 at a frame rate of M frames / s. In actual applications, M can be selected as 25, 26, 27, 28, 29, or 30, or other higher frame rate values, and N can be selected as 2, 3, 4, 5, or 6, or other lower frame rate values. Video images recorded at a frame rate of M frames / s are smoother, while videos recorded at a frame rate of N frames / s are relatively jerky, but can still roughly record the actual scene to a certain extent, and the video data still has a certain purpose.

[0041] Please refer to Figure 2, which shows a schematic diagram of the connection between frames at different time units within a preset time period. In Figure 2, vertical solid lines represent frames used to record the actual image, and vertical dashed lines represent skipped frames. Skipped frames are not used to record the actual image. The example in Figure 2 shows that: M = 25, N = 3.

[0042] The unit time may be 1 second. When the frame connection module 34 processes the frame images recorded by the standard frame recording module 32 and the skip frame recording module 33, there are four specific cases:

[0043] 1. The standard frame recording module 32 records real images within two adjacent units of time, i.e., within two adjacent seconds. The frame connection module 34 overlaps the frames recorded at the end of the first second and the beginning of the second of the two adjacent seconds, so that the end of the first second and the beginning of the second are the same time.

[0044] 2. The skipping frame recording module 33 records real images in two adjacent units of time, i.e., two adjacent seconds. The frame connection module 34 overlaps the frames recorded at the end of the first second and the beginning of the second second of the two adjacent seconds.

[0045] 3. Within one unit of time, the standard frame recording module 32 records the real image within one second. Within the next unit of time, the skip frame recording module 33 records the real image within the next second. The frame connection module 34 overlaps the frames recorded at the end of one second with the beginning of the next second, so that the end of one second and the beginning of the next second are the same moment.

[0046] 4. In one unit of time, the real picture is recorded by the jump frame recording module 33 within one second, and the real picture is recorded by the standard frame recording module 32 within the next unit of time. The frame connection module 34 overlaps the frame pictures recorded at the end of one second with the beginning of the next second.

[0047] As shown in FIG. 1 , the video image communication transmission module 29 is in communication connection with the video output module 36 , and is used to transmit the continuous video data regenerated by the continuous frame regeneration module 35 .

[0048] The storage module 30 is wirelessly connected to the video image communication transmission module 29 for receiving and storing video data. The storage module can store video data for a longer period of time, and the storage module 30 has a higher utilization rate.

[0049] Storage module 30 stores new video data on a rolling basis over a three-month storage period and deletes overdue video data. Because some of the stored video data is recorded at a lower frame rate of N frames / s, this increases the time period during which storage module 30 can store video data, allowing it to store longer periods of video data. A three-month rolling storage period is sufficient for video data. Video data older than three months is automatically deleted. If a copy of video data within three months is needed, it can be removed from storage module 30 in advance.

[0050] Please refer to Figure 3, which is a flow chart of setting the frame rate mode in an embodiment of the present application. As shown in Figure 3, the camera assembly 100 also includes a real environment dynamics monitoring module 37, a dynamics comparison module 38 and a frame rate setting module 39 that are sequentially connected in communication.

[0051] The real-world dynamics monitoring module 37 is used to identify people and vehicles and monitor their average speed within a preset monitoring period. This average speed is used as the dynamics indicator, with the value and unit of the average speed corresponding to the dynamics indicator. The preset monitoring period can be 1, 2, or 3 seconds. The real-world dynamics monitoring module 37 monitors the displacement of the target object within the preset monitoring period and calculates the average speed by dividing the displacement by the data from the preset monitoring period.

[0052] The dynamic degree comparison module 38 is used to compare the dynamic degree with a preset standard threshold. The degree of necessity for video image acquisition when the dynamic degree does not exceed the standard threshold is lower than the degree of necessity for video image acquisition when the dynamic degree exceeds the standard threshold. When the dynamic degree exceeds the standard threshold, the frame rate setting module 39 sends a signal recorded in the A frame rate mode to the jump frame recording module 33, and the standard frame recording module 32 records the real picture at a frame rate of M frames / s. When the dynamic degree does not exceed the standard threshold, the frame rate setting module 39 sends a signal recorded in the B frame rate mode to the jump frame recording module 33, and the real picture is recorded at a frame rate of N frames / s through the jump frame recording module 33.

[0053] In specific analysis, the monitoring objects and preset standard thresholds of the real environment dynamics monitoring module 37 are divided into the following three cases: a, b and c:

[0054] a. When the real environment dynamics monitoring module 37 detects a person: the standard threshold is 5 km / h. The real environment dynamics monitoring module 37 monitors the average moving speed of the person within the preset monitoring time period. When the average speed of the person exceeds 5 km / h, it indicates that the person is running, which means that an emergency or accidental safety incident may have occurred. For example, the person may have stolen the belongings of other people on the road and then fled, or may be more likely to collide with other people or vehicles while running. At this time, the necessity of capturing video images is high, so the real picture is recorded at a frame rate of M frames / s, and the final video picture is smoother.

[0055] b. When the real-world dynamics monitoring module 37 simultaneously monitors a non-motor vehicle and its driver: the standard threshold is 25 km / h, and the real-world dynamics monitoring module 37 monitors the average speed of the non-motor vehicle within the preset monitoring time period; when the average speed of the driver of the non-motor vehicle exceeds 25 km / h, it is considered speeding, indicating that an emergency may have occurred or the probability of a traffic accident is high. At this time, it is necessary to capture video images. In this case, it is necessary to record the real image at a frame rate of M frames / s, so that the final video image is smoother;

[0056] c. When the real environment dynamics monitoring module 37 detects a motor vehicle: the standard threshold is 50 km / h, and the real environment dynamics monitoring module 37 monitors the average moving speed of the motor vehicle within the preset monitoring time period; for high-rise buildings with glass curtain walls, they are generally built near the main roads with center lines in the city. When the average speed of the motor vehicle exceeds 50 km / h, it indicates that the motor vehicle is speeding and the probability of a traffic accident is high. At this time, the necessity of collecting video images is high, and the real picture needs to be recorded at a frame rate of M frames / s.

[0057] When the dynamics of the monitored object in at least one of the three situations above exceeds the standard threshold for the corresponding situation, the necessity of capturing video images is high. The frame rate setting module 39 sends a signal to the skip frame recording module 33 to record according to the A frame rate mode, and the standard frame recording module 32 records the real scene at a frame rate of M frames / s, recording a smoother video image. When the dynamics of the monitored object do not exceed the standard threshold for the corresponding situation in any of the three situations above, it indicates that the person is not running, and neither the non-motor vehicle nor the motor vehicle is speeding. The probability of an emergency or accident is low, and the necessity of capturing video images is low. The frame rate setting module 39 sends a signal to the skip frame recording module 33 to record according to the B frame rate mode, and the skip frame recording module 33 records the real scene at a frame rate of N frames / s. At this time, the real scene can be recorded at the lower frame rate of N frames / s, saving storage space in the storage module 30.

[0058] This embodiment can record real images at different frame rates under different circumstances, thereby saving storage space and extending the storage time of video data, and improving the utilization rate of storage space. When the necessity of capturing video images is high, the real images are recorded at a frame rate of M frames / s. When the necessity of capturing video images is low, the real images are recorded at a lower frame rate of N frames / s. When the storage space of the storage module 30 is determined, the total duration of video data that can be stored in the storage module 30 is longer, that is, video data can be stored for a longer time, and the storage space utilization rate of the storage module 30 is higher. For videos generated at a frame rate of M frames / s, the fluency is higher and what is happening around the building's glass curtain wall can be displayed more clearly. For videos generated at a frame rate of N frames / s, the fluency is lower, but what is happening around the building's glass curtain wall can still be displayed to a certain extent, and the video data is still usable.

[0059] In other embodiments, instead of using the real environment dynamics monitoring module 37, the dynamics comparison module 38, and the frame rate setting module 39 to set the frame rate in different situations, the following settings are performed:

[0060] When the preset time period is one day, under the 24-hour timekeeping method, 0:00 to 7:00 is nighttime, when there are fewer people and vehicles around the building. However, from 7:00 to 24:00, there are more people and vehicles around the building, and the probability of accidents is higher. Therefore, the necessity of capturing video images from 0:00 to 7:00 is lower than that from 7:00 to 24:00. The skip frame recording module 33 captures video images from 0:00 to 7:00 at a frame rate of N frames / s, while the standard frame recording module 32 captures video images from 7:00 to 24:00 at a frame rate of M frames / s.

[0061] Among them, the height and orientation control module 31 is used to control the height and video image acquisition orientation of the camera module 22. By controlling the height and orientation of the camera module 22, the viewing angle of the camera module 22 for collecting video data can be adjusted, making it more flexible to use.

[0062] Please refer to Figure 4, which is a schematic diagram of the structure of the height and orientation control module 31 in an embodiment of the present application. The height and orientation control module 31 includes a lift control mechanism 23 for controlling the height of the camera module 22 and enabling it to be raised and lowered on the glass curtain wall, and an orientation control mechanism 26 for controlling the orientation of the camera module 22. Thus, the height and orientation of the camera module 22 can be controlled independently. The components of the height and orientation control module 31 are preferably made of lightweight materials.

[0063] As shown in Figures 4 and 5, in some embodiments, the lifting control mechanism 23 includes a frame 11, two sets of suction cup adsorption lifting mechanisms 24 and a servo motor (not shown), wherein the two sets of suction cup adsorption lifting mechanisms 24 are arranged side by side on the frame 11 and can climb and descend on the glass curtain wall to achieve height control, and the servo motor is arranged on the frame 11 and is used to drive the suction cup adsorption lifting mechanism 24 to move to achieve rolling adsorption.

[0064] In some embodiments, the suction cup-type lifting mechanism 24 includes two synchronous pulleys 12, a synchronous belt 13, multiple fixed rods 16, and multiple suction cups 14. The two synchronous pulleys 12 are rotatably mounted on the frame 11 and driven by a servo motor. The synchronous belt 13 is fitted and meshed with the two synchronous pulleys 12. Multiple fixed rods 16 are evenly arranged on the outer circumference of the synchronous belt 13. Multiple suction cups 14 are respectively mounted on the multiple fixed rods 16 and perpendicular to the synchronous belt 13. The servo motor can drive the synchronous pulleys 12 to rotate forward and reverse, thereby driving the synchronous belt 13 forward and reverse, which in turn drives the suction cups 14 to move. The rolling suction cups 14 on the glass curtain wall enable the lifting control mechanism 23 to ascend and descend on the glass curtain wall. In the initial state, a row of suction cups 14 near one side of the glass curtain wall is pressed against the glass curtain wall, squeezing out the air inside the row of suction cups 14, allowing the suction cups 14 to adhere to the glass curtain wall due to the pressure difference between the inside and outside of the row. As the suction cup adsorption lifting mechanism 24 is raised and lowered, the remaining suction cups 14 in the forward direction will sequentially move to the glass curtain wall and be placed in the same row as the suction cups 14 already adsorbed on the glass curtain wall. Under the action of the suction cups 14 already adsorbed on the glass curtain wall, the suction cups 14 moved to the glass curtain wall can be pressed toward the glass curtain wall via the fixed rod 16, synchronous belt 13, and synchronous pulley 12, thereby gradually squeezing out the air inside the suction cups 14 and allowing the suction cups 14 to adhere to the glass curtain wall. As the suction cup adsorption lifting mechanism 24 is raised and lowered, different suction cups 14 can be alternately adsorbed on the glass curtain wall, thereby adjusting the monitoring height of the camera module 22.

[0065] As shown in Figures 4 to 6, the suction cup adsorption lifting mechanism 24 also includes multiple sets of vacuum assemblies 25 corresponding to the multiple suction cups 14. Each vacuum assembly 25 includes a connecting tube 15, a piston 17, a connecting rod 18, a rotating plate 19, and two rollers 20. The connecting tube 15 is connected to the corresponding suction cup 14, the piston 17 is slidingly and sealingly mounted on the connecting tube 15, one end of the connecting rod 18 is connected to the piston 17, and the other end of the connecting rod 18 is rotatably connected to the rotating plate 19. The two rollers are rotatably mounted side by side on the rotating plate 19. The lifting control mechanism 23 also includes a guide ring 21, which is located inside the two rollers 20 and is used to guide the two rollers 20. The guide ring 21 includes a first straight bar 211, two curved bars 212, two second straight bars 213, two connecting bars 214, and a third straight bar 215. The two curved bars 212 are both semicircular, with one end tangentially connected to the two ends of the first straight bar 211. One end of the second straight portion 213 is tangentially connected to the other end of the curved portion 212. The other end of the second straight portion 213 is tangentially connected to one end of the connecting portion 214. The connecting portion 214 gradually bends in an S-shape toward the first straight portion 211 as it moves away from the second straight portion 213. Both ends of the third straight portion 215 are tangentially connected to the ends of the two connecting portions 214 away from the second straight portion 213. The first straight portion 211, the second straight portion 213, and the third straight portion 215 are arranged in parallel.

[0066] The guide ring 21 is fixed on the frame 11, and the multiple groups of exhaust components 25 move with the movement of the suction cup 14. When the suction cup 14 is just adsorbed on the glass curtain wall, as the synchronous belt 13 rotates, the synchronous belt 13 will drive the suction cup 14 to move through the fixed rod 16. At the same time, the two rollers 20 in the exhaust component 25 corresponding to the suction cup 14 gradually roll from the second straight strip portion 213 to the third straight strip portion 215 through the connecting strip portion 214. The rollers 20 will drive the piston 17 to move through the rotating plate 19 and the connecting rod 18. The piston 17 slides outward in the connecting tube 15, thereby increasing the volume of the space formed between the glass curtain wall, the suction cup 14, the connecting tube 15 and the piston 17, thereby increasing the air pressure difference inside and outside the suction cup 14, thereby further improving the reliability of the suction cup 14 adsorbed on the glass curtain wall. When the suction cup 14 gradually separates from the glass curtain wall, the roller 20 in the corresponding exhaust assembly 25 rolls from the third straight portion 215 to the second straight portion 213 via the connecting portion 214, and the piston 17 slides toward the inside of the connecting tube 15, reducing the volume of the space formed between the glass curtain wall, the suction cup 14, the connecting tube 15, and the piston 17, thereby reducing the pressure difference between the inside and outside of the suction cup 14, and facilitating the separation of the suction cup 14 from the glass curtain wall.

[0067] In order to further enable the suction cup 14 to be more smoothly adsorbed on the glass curtain wall during movement, a blowing device can be provided on the frame 11, which blows air away from the glass curtain wall, thereby pressing the suction cup 14 in the suction cup adsorption lifting mechanism 24 onto the glass curtain wall through the reaction force.

[0068] As shown in Figure 4, camera module 22 includes a first camera 1 and two second cameras 2 symmetrically located on either side of the first camera 1. Both the first camera 1 and the second camera 2 integrate a standard frame recording module 32, a skip frame recording module 33, a frame connection module 34, a continuous frame regeneration module 35, and a video output module 36. The first camera 1 is positioned midway between the two second cameras 2 to capture real-world images, while the second cameras 2 on either side can capture real-world images from other perspectives. Working together, the first camera 1 and the two second cameras 2 can capture real-world images across a wider range of viewing angles, expanding the monitoring range of the surrounding environment of high-rise buildings.

[0069] As shown in Figure 7, the orientation control mechanism 26 includes a pitch adjustment assembly 27, which is used to adjust the pitch tilt angle of the camera module 22. The pitch adjustment assembly 27 includes a mounting seat 10, a motor 9, a rotating frame 8 and a mounting cover 7. The mounting seat 10 is set on the frame 11. The motor 9 is mounted on the mounting seat 10. The rotating frame 8 is set on the mounting seat 10 and connected to the motor 9. The mounting cover 7 is set on the rotating frame 8. The first camera 1 and the two second cameras 2 of the camera module 22 are all installed in the mounting cover 7, and the bottom end of the mounting cover 7 has a camera channel. The first camera 1 and the two second cameras 2 of the camera module 22 shoot through the camera channel. The motor 9 adjusts the orientation of the first camera 1 and the second camera 2 by driving the rotating frame 8 to rotate, thereby achieving the purpose of adjusting the monitoring angle orientation of the first camera 1 and the second camera 2.

[0070] Please refer to Figure 7 again. The orientation control mechanism 26 also includes a left-right adjustment component 28. The left-right adjustment component 28 is used to adjust the angle of the two second cameras 2 of the camera module 22 relative to the first camera 1. The left-right adjustment component 28 includes two rotating shafts 3, two driven gears 4, two driving gears 5 and a motor 6. The two rotating shafts 3 and the two driving gears 5 are both rotatably arranged on the inner side of the mounting cover 7. Each rotating shaft 3 is mounted with a second camera 2. Each rotating shaft 3 is connected to a driven gear 4, and each driven gear 4 is meshed with a driving gear 5, and the two driving gears 5 are meshed with each other. The motor 6 drives one of the driving gears 5 to rotate to control the two second cameras 2 to expand or retract in an inverted V shape. The output end of the motor 6 can rotate forward and reverse. The motor 6 drives one driving gear 5 to rotate, and the driving gear 5 drives the other driving gear 5 to rotate. The two driving gears 5 respectively drive the two driven gears 4 to rotate. The two driven gears 4 drive the second cameras 2 to rotate through the corresponding rotating shafts 3, thereby realizing the two second cameras 2 rotating towards each other and away from each other.

[0071] Next, the specific structure of a camera assembly 100 provided in an embodiment of the present application is introduced.

[0072] As shown in FIG4 and FIG5, the camera assembly 100 includes:

[0073] Camera module 22;

[0074] The lifting control mechanism 23 includes:

[0075] The frame 11, the camera module 22 is connected to the frame 11;

[0076] A suction cup adsorption type lifting mechanism 24, which is provided on the frame 11; and

[0077] A servo motor is provided on the frame 11 and is used to drive the suction cup adsorption type lifting mechanism 24 to move, so as to achieve rolling adsorption of the glass curtain wall; and

[0078] Guide ring 21;

[0079] The suction cup adsorption type lifting mechanism 24 includes a plurality of suction cups 14 and a plurality of suction components 25;

[0080] Among them, multiple groups of air extraction components 25 correspond to and are connected to multiple suction cups 14 one by one, and multiple groups of air extraction components 25 are respectively connected to the guide ring 21;

[0081] Among them, when the exhaust component 25 is located in the first position of the guide ring 21, the exhaust component 25 increases the adsorption pressure between the suction cup 14 and the glass curtain wall, and the suction cup 14 is adsorbed on the glass curtain wall; when the exhaust component 25 is located in the second position of the guide ring 21, the exhaust component 25 reduces the adsorption pressure between the suction cup 14 and the glass curtain wall, and the suction cup 14 is separated from the glass curtain wall.

[0082] 4 , the camera module 22 includes a first camera 1 and two second cameras 2 symmetrically distributed on either side of the first camera 1. It is understood that in other embodiments, the camera module 22 may include one camera or multiple cameras, which is not limited thereto.

[0083] Thus, in this application, the camera assembly 100, through the mechanical coordination of the air extraction assembly 25 and the guide ring 21, achieves mechanical adjustment of the adsorption pressure between the suction cup 14 and the glass curtain wall, thereby achieving adsorption-type connection or separation of the suction cup 14 and the glass curtain wall. Compared with the electromagnetic adsorption structure, the air extraction assembly 25 does not require electricity, which saves energy and simplifies the structure of the suction cup adsorption lifting mechanism 24. Moreover, by changing the installation position of the camera assembly 100, the shooting angle of the camera module 22 is changed, simplifying the adsorption and separation structure between the camera assembly 100 and the glass curtain wall, eliminating the electronic control components required for electromagnetic adsorption.

[0084] In some embodiments, as shown in FIG4 and FIG5, the suction cup adsorption type lifting mechanism 24 is a crawler type adsorption mechanism, which can achieve adsorption type lifting. Specifically, the suction cup adsorption type lifting mechanism 24 includes two synchronous pulleys 12, a synchronous belt 13 and a plurality of fixing rods 16;

[0085] The synchronous pulley 12 is rotatably mounted on the frame 11 and driven by a servo motor.

[0086] The synchronous belt 13 is meshed and connected to the two synchronous pulleys 12;

[0087] Among them, a plurality of fixing rods 16 are evenly arranged on the outer peripheral surface of the synchronous belt 13;

[0088] The plurality of suction cups 14 are respectively connected to the ends of the plurality of fixing rods 16 away from the synchronous belt 13 and are perpendicular to the synchronous belt 13;

[0089] The servo motor drives the synchronous pulley 12 to rotate forward or reverse, and then drives the synchronous belt 13 to rotate forward or reverse accordingly. The movement of the synchronous belt 13 drives the multiple suction cups 14 to move, so as to achieve rolling adsorption of the glass curtain wall.

[0090] Therefore, in the present application, the crawler-type adsorption mechanism is used to achieve ascent or descent through rolling adsorption, and the adsorption force is strong and stable, and it is not easy to cause accidental falling off.

[0091] In some embodiments, as shown in FIG5 , each air extraction assembly 25 includes:

[0092] Connecting pipe 15, connecting pipe 15 is connected with the corresponding suction cup 14;

[0093] A piston 17 is provided on the connecting pipe 15 in a sliding seal;

[0094] a connecting rod 18 , one end of which is connected to the piston 17 ;

[0095] The roller 20, the other end of the connecting rod 18 is connected to the roller 20;

[0096] The roller 20 is connected to the guide ring 21 , and the roller 20 moves along the circumferential direction of the guide ring 21 under the guidance of the guide ring 21 .

[0097] Thus, in the present application, the connecting tube 15 is connected to the corresponding suction cup 14, and the volume of the space formed between the glass curtain wall, the suction cup 14, the connecting tube 15 and the piston 17 is changed by changing the position of the piston 17 in the connecting tube 15, thereby changing the adsorption pressure between the suction cup 14 and the glass curtain wall, thereby achieving adsorption or separation of the suction cup 14 and the glass curtain wall.

[0098] In some embodiments, as shown in Figure 5, the connecting tube 15 and the connecting rod 18 are both L-shaped, and the connecting tube 15 and the connecting rod 18 are combined into a U-shape, which is used to connect the suction cup 14 located on the outer surface of the synchronous pulley 12 and the guide ring 21 located on the inner surface of the synchronous pulley 12.

[0099] Thus, the connecting tube 15 and the connecting rod 18 are combined into a U shape, which allows the suction cup 14 to be located on the outer circumference of the synchronous pulley 12, and the guide ring 21 to be located on the inner circumference of the synchronous pulley 12, making the suction cup adsorption lifting mechanism 24 more compact and miniaturized.

[0100] In some embodiments, the number of rollers 20 is two, and the air extraction assembly 25 further includes:

[0101] A rotating plate 19, one end of the rotating plate 19 is connected to the end of the connecting rod 18 away from the piston 17, and the other end of the rotating plate 19 is connected to two rollers 20;

[0102] The guide ring 21 is clamped between the two rollers 20 .

[0103] Therefore, the rotating plate 19 is a strip plate, forming a T-shaped structure between the rotating plate 19 and the connecting rod 18, and the two ends of the rotating plate 19 are respectively used to connect a roller 20, and the guide ring 21 is clamped between the two rollers 20. Therefore, the connection between the guide ring 21 and the two rollers 20 is more stable and reliable.

[0104] In some embodiments, as shown in FIG6 , the guide ring 21 includes:

[0105] a first straight portion 211;

[0106] Two arc-shaped strip portions 212 , each of which is semicircular and has one end tangentially connected to the two ends of the first straight strip portion 211 ;

[0107] Two second straight strip portions 213 , one end of each second straight strip portion 213 being tangentially connected to the other end of one arc-shaped strip portion 212 ;

[0108] Two connecting strips 214 , one end of each connecting strip 214 being tangentially connected to the other end of each of the two second straight strips 213 and gradually bending in an S-shape toward the first straight strip 211 in a direction away from the second straight strip 213 ;

[0109] The third straight portion 215 has two ends tangentially connected to the ends of the two connecting portions 214 away from the second straight portion 213;

[0110] The first straight portion 211, the second straight portion 213 and the third straight portion 215 are arranged in parallel;

[0111] The first position is the third straight portion 215 , and the second position is the second straight portion 213 and the first straight portion 211 .

[0112] Therefore, in this application, by designing the structure of the guide ring 21, the adsorption pressure between the suction cup 14 and the glass curtain wall can be achieved through the mechanical cooperation of the exhaust assembly 25 and the guide ring 21, which simplifies the structure, eliminates the electromagnetic structure, and reduces costs.

[0113] In some embodiments, when the exhaust assembly 25 is located at the third position of the guide ring 21, the suction cup 14 changes from the adsorption state in which it is adsorbed on the glass curtain wall to the separation state in which it is separated from the glass curtain wall, or the suction cup 14 changes from the separation state in which it is separated from the glass curtain wall to the adsorption state in which it is adsorbed on the glass curtain wall, wherein the third position is two connecting strips 214.

[0114] Therefore, in the present application, when the roller 20 moves from the second straight portion 213 via the connecting portion 214 to the third straight portion 215, the suction pressure between the suction cup 14 and the glass curtain wall increases, and the suction cup 14 gradually transitions from a state of separation from the glass curtain wall to a state of adhesion. Conversely, when the roller 20 moves from the third straight portion 215 via the connecting portion 214 to the second straight portion 213, the suction pressure between the suction cup 14 and the glass curtain wall decreases, and the suction cup 14 gradually transitions from a state of adhesion to a state of separation from the glass curtain wall.

[0115] In some embodiments, the camera assembly 100 further includes an orientation control mechanism 26 , which is connected between the camera module 22 and the frame 11 . The orientation control mechanism 26 adjusts the orientation of the camera module 22 .

[0116] Therefore, in the present application, the shooting angle of the camera module of the camera assembly can be adjusted by the orientation control mechanism 26, and the shooting angle of view is wider.

[0117] In some embodiments, as shown in FIG7 , the azimuth control mechanism 26 includes a pitch adjustment component 27 , and the pitch adjustment component 27 includes:

[0118] Mounting base 10, the mounting base 10 is mounted on the frame 11;

[0119] Motor 9, motor 9 is mounted on a mounting base 10;

[0120] The rotating frame 8 is arranged on the mounting base 10 and connected to the motor 9;

[0121] Mounting cover 7, which is mounted on mounting base 10 and connected to the output shaft of rotating frame 8;

[0122] The camera module 22 is installed in the mounting cover 7; the rotational movement of the output shaft of the motor 9 drives the mounting cover 7 to rotate and then drives the camera module 22 to adjust the pitch angle.

[0123] Therefore, in the present application, through the pitch adjustment assembly 27, the rotational movement of the output shaft of the motor 9 drives the mounting cover 7 to rotate and then drives the camera module 22 to adjust the pitch angle, and the camera module 22 has a larger viewing angle range.

[0124] In some embodiments, as shown in Figure 7, the first camera 1 is installed in the mounting cover 7, and the orientation control mechanism 26 also includes a left and right adjustment component 28, which is connected between the two second cameras 2 and the inner wall of the mounting cover 7. The left and right adjustment component 28 adjusts the angle of the two second cameras 2 relative to the first camera 1.

[0125] Therefore, not only can the pitch angles of the first camera 1 and the two second cameras 2 be adjusted through the pitch adjustment component 27, but the angles of the two second cameras 2 relative to the first camera 1 can also be adjusted through the left and right adjustment component 28, which can further expand the adjustable range of the viewing angle of the first camera 1 and the two second cameras 2 to meet the viewing angle requirements in more scenarios.

[0126] In other embodiments, when the pitch adjustment assembly 27 is omitted, the left and right adjustment assembly 28 does not need to be connected to the inner wall of the mounting cover 7 , but is directly connected between the two second cameras 2 and the frame 11 .

[0127] In some embodiments, the left and right adjustment assembly 28 includes:

[0128] Two rotating shafts 3, used to respectively mount two second cameras 2;

[0129] Two driven gears 4, each driven gear 4 is connected to a rotating shaft 3;

[0130] Two driving gears 5, each driving gear 5 is meshedly connected with a driven gear 4, and the two driving gears 5 are meshedly connected with each other;

[0131] The motor 6 is connected to a driving gear 5 to control the two second cameras 2 to expand or retract in an inverted V shape to adjust the angle of the two second cameras 2 relative to the first camera 1.

[0132] Therefore, in this application, a driving gear 5 is driven by a motor 6, and one driving gear 5 is engaged with another driving gear 5, which can then drive two driven gears 4 to rotate. The two driven gears 4 each drive the corresponding second camera 2, so that the two second cameras 2 move toward or away from each other, which can change the shooting range of the two second cameras 2 to meet the shooting needs within a larger shooting range.

[0133] Next, the specific structure of another camera assembly provided in an embodiment of the present application is introduced.

[0134] In some embodiments, the camera assembly 100 includes:

[0135] Rack 11;

[0136] The camera module 22 includes a first camera 1 and two second cameras 2 symmetrically distributed on both sides of the first camera 1. The first camera 1 is connected to the frame 11;

[0137] The orientation control mechanism 26 includes a left-right adjustment component 28 , which is connected between the two second cameras 2 and the frame. The left-right adjustment component 28 adjusts the angle of the two second cameras 2 relative to the first camera 1 .

[0138] Therefore, in this application, the angles of the two second cameras 2 relative to the first camera 1 can be adjusted through the left and right adjustment components 28, and the shooting ranges of the two second cameras 2 can be changed to meet the shooting needs within a larger shooting range.

[0139] In some embodiments, the left and right adjustment assembly 28 includes:

[0140] Two rotating shafts 3, used to respectively mount two second cameras 2;

[0141] Two driven gears 4, each driven gear 4 is connected to a rotating shaft 3;

[0142] Two driving gears 5, each driving gear 5 is meshedly connected with a driven gear 4, and the two driving gears 5 are meshedly connected with each other;

[0143] The motor 6 is used to connect to a driving gear 5 to control the two second cameras 2 to expand or retract in an inverted V shape, thereby adjusting the angle of the two second cameras 2 relative to the first camera 1.

[0144] Therefore, in this application, a driving gear 5 is driven by a motor 6, and one driving gear 5 is engaged with another driving gear 5, which can then drive two driven gears 4 to rotate. The two driven gears 4 each drive the corresponding second camera 2, so that the two second cameras 2 move toward or away from each other, which can change the shooting range of the two second cameras 2 to meet the shooting needs within a larger shooting range.

[0145] In some embodiments, the azimuth control mechanism 26 further includes a pitch adjustment component 27, and the pitch adjustment component 27 includes:

[0146] Mounting base 10, the mounting base 10 is mounted on the frame 11;

[0150] The first camera 1 is mounted in the mounting cover 7, and the two second cameras 2 are mounted in the mounting cover 7 via the left and right adjustment components 28;

[0151] The rotation of the output shaft of the motor 9 drives the mounting cover 7 to rotate, thereby driving the camera module 22 to adjust the pitch angle.

[0152] Therefore, in this application, the motor 9 drives the mounting cover 7 to drive the first camera 1 and the second camera 2 to perform pitch motion as a whole to adjust the orientation of the first camera 1 and the second camera 2, thereby achieving the purpose of adjusting the orientation of the monitoring view of the first camera 1 and the second camera 2.

[0153] In some embodiments, the camera assembly 100 further includes a lifting control mechanism 23, and the lifting control mechanism 23 includes:

[0154] Rack 11;

[0155] A suction cup adsorption type lifting mechanism 24, which is provided on the frame 11; and

[0156] A servo motor is provided on the frame 11 and is used to drive the suction cup adsorption lifting mechanism 24 to move, so as to achieve rolling adsorption of the glass curtain wall;

[0157] The camera assembly 100 further includes a guide ring 21;

[0158] The suction cup adsorption type lifting mechanism 24 includes a plurality of suction cups 14 and a plurality of suction components 25;

[0159] Among them, multiple groups of air extraction components 25 correspond to and are connected to multiple suction cups 14 one by one, and multiple groups of air extraction components 25 are respectively connected to the guide ring 21;

[0160] Among them, when the exhaust component 25 is located in the first position of the guide ring 21, the exhaust component 25 increases the adsorption pressure between the suction cup 14 and the glass curtain wall, and the suction cup 14 is adsorbed on the glass curtain wall; when the exhaust component 25 is located in the second position of the guide ring 21, the exhaust component 25 reduces the adsorption pressure between the suction cup 14 and the glass curtain wall, and the suction cup 14 is separated from the glass curtain wall.

[0161] Thus, in this application, the camera assembly 100, through the mechanical coordination of the air extraction assembly 25 and the guide ring 21, achieves mechanical adjustment of the adsorption pressure between the suction cup 14 and the glass curtain wall, thereby achieving adsorption-type connection or separation of the suction cup 14 and the glass curtain wall. Compared with the electromagnetic adsorption structure, the air extraction assembly 25 does not require electricity, which saves energy and simplifies the structure of the suction cup adsorption lifting mechanism 24. Moreover, by changing the installation position of the camera assembly 100, the shooting angle of the camera module 22 is changed, simplifying the adsorption and separation structure between the camera assembly 100 and the glass curtain wall, eliminating the electronic control components required for electromagnetic adsorption.

[0162] In some embodiments, the suction cup adsorption type lifting mechanism 24 includes two synchronous pulleys 12, a synchronous belt 13 and a plurality of fixing rods 16;

[0163] The synchronous pulley 12 is rotatably mounted on the frame 11 and driven by a servo motor.

[0164] The synchronous belt 13 is meshed and connected to the two synchronous pulleys 12;

[0165] Among them, a plurality of fixing rods 16 are evenly arranged on the outer peripheral surface of the synchronous belt 13;

[0166] The plurality of suction cups 14 are respectively connected to the ends of the plurality of fixing rods 16 away from the synchronous belt 13 and are perpendicular to the synchronous belt 13;

[0167] The servo motor drives the synchronous pulley 12 to rotate forward or reverse, and then drives the synchronous belt 13 to rotate forward or reverse accordingly. The movement of the synchronous belt 13 drives the multiple suction cups 14 to move, so as to achieve rolling adsorption of the glass curtain wall.

[0168] Therefore, in the present application, the crawler-type adsorption mechanism is used to achieve ascent or descent through rolling adsorption, and the adsorption force is strong and stable, and it is not easy to cause accidental falling off.

[0169] In some embodiments, each air extraction assembly 25 includes:

[0170] Connecting pipe 15, connecting pipe 15 is connected with the corresponding suction cup 14;

[0171] A piston 17 is provided on the connecting pipe 15 in a sliding seal;

[0172] a connecting rod 18 , one end of which is connected to the piston 17 ;

[0173] The roller 20, the other end of the connecting rod 18 is connected to the roller 20;

[0174] The roller 20 is connected to the guide ring 21 , and the roller 20 moves along the circumferential direction of the guide ring 21 under the guidance of the guide ring 21 .

[0175] Thus, in the present application, the connecting tube 15 is connected to the corresponding suction cup 14, and the volume of the space formed between the glass curtain wall, the suction cup 14, the connecting tube 15 and the piston 17 is changed by changing the position of the piston 17 in the connecting tube 15, thereby changing the adsorption pressure between the suction cup 14 and the glass curtain wall, thereby achieving adsorption or separation of the suction cup 14 and the glass curtain wall.

[0176] In some embodiments, the guide ring 21 includes:

[0177] a first straight portion 211;

[0178] Two arc-shaped strip portions 212 , each of which is semicircular and has one end tangentially connected to the two ends of the first straight strip portion 211 ;

[0179] Two second straight strip portions 213 , one end of each second straight strip portion 213 being tangentially connected to the other end of one arc-shaped strip portion 212 ;

[0180] Two connecting strips 214 , one end of each connecting strip 214 being tangentially connected to the other end of each of the two second straight strips 213 and gradually bending in an S-shape toward the first straight strip 211 in a direction away from the second straight strip 213 ;

[0181] The third straight portion 215 has two ends tangentially connected to the ends of the two connecting portions 214 away from the second straight portion 213;

[0182] The first straight portion 211, the second straight portion 213 and the third straight portion 215 are arranged in parallel;

[0183] The first position is the third straight portion 215 , and the second position is the second straight portion 213 and the first straight portion 211 .

[0184] Therefore, in this application, by designing the structure of the guide ring 21, the adsorption pressure between the suction cup 14 and the glass curtain wall can be achieved through the mechanical cooperation of the exhaust assembly 25 and the guide ring 21, which simplifies the structure, eliminates the electromagnetic structure, and reduces costs.

[0185] In some embodiments, when the vacuum assembly 25 is located at the third position of the guide ring 21, the suction cup 14 changes from being adsorbed on the glass curtain wall to being separated from the glass curtain wall, or the suction cup 14 changes from being separated from the glass curtain wall to being adsorbed on the glass curtain wall, wherein the third position is the two connecting strips 214.

[0186] Therefore, in the present application, when the roller 20 moves from the second straight portion 213 via the connecting portion 214 to the third straight portion 215, the suction pressure between the suction cup 14 and the glass curtain wall increases, and the suction cup 14 gradually transitions from a state of separation from the glass curtain wall to a state of adhesion. Conversely, when the roller 20 moves from the third straight portion 215 via the connecting portion 214 to the second straight portion 213, the suction pressure between the suction cup 14 and the glass curtain wall decreases, and the suction cup 14 gradually transitions from a state of adhesion to a state of separation from the glass curtain wall.

[0187] Next, the photo taking control process of the camera assembly 100 provided in the embodiment of the present application is introduced.

[0188] In some embodiments, as shown in FIG1 , the camera module 22 further includes a control module for each camera, the control module including:

[0189] The standard frame recording module 32 is used to record the real picture according to the preset standard frame rate M frames / s during part of the unit time in the preset time period;

[0190] The skip frame recording module 33 is configured to extract N frames from the M frames at the frame rate of M frames / s per second during the remaining unit time of the preset time period and record the real images at the frame rate of N frames / s;

[0191] The frame connection module 34 is configured to communicate with the standard frame recording module 32 and the skip frame recording module 33 and to overlap the frame image at the end of any unit time in the preset time period with the frame image at the beginning of the next adjacent unit time;

[0192] The continuous frame regeneration module 35 is configured to communicate with the frame connection module 34 and select and retain one of the overlapping frames within a preset time period to regenerate a continuous frame video; and

[0193] a video output module 36 for communicating with the continuous frame regeneration module 35 and outputting video data within a preset time period; wherein M and N are both positive integers, and N<M, and the necessity level of the video images captured by the skip frame recording module 33 at a frame rate of N frames / s is lower than the necessity level of the video images captured by the standard frame recording module 32 at a frame rate of M frames / s;

[0194] The video image communication transmission module 29 is connected to the video output module 36 for transmitting video data;

[0195] The storage module 30 is wirelessly connected to the video image communication transmission module 29 and is used to receive and store video data.

[0196] Therefore, in the present application, the necessity degree of the video images collected by the jump frame recording module 33 at a frame rate of N frames / s is lower than the necessity degree of the video images collected by the standard frame recording module 32 at a frame rate of M frames / s. The real pictures with higher necessity can be recorded by the standard frame recording module 32 at the preset standard frame rate of M frames / s, and the real pictures with lower necessity can be recorded by the jump frame recording module 33 at the frame rate of N frames / s. This can reduce the size of the video data recorded by the camera module 22, and reduce the data space occupied by the camera module 22 while meeting the necessity requirements.

[0199] The dynamic degree comparison module 38 is used to compare the dynamic degree with a preset standard threshold value to determine whether the dynamic degree exceeds the standard threshold value. The degree of necessity of video image acquisition when the dynamic degree does not exceed the standard threshold value is lower than the degree of necessity of video image acquisition when the dynamic degree exceeds the standard threshold value; when the dynamic degree exceeds the standard threshold value, the frame rate setting module 39 sends a signal recorded in the A frame rate mode to the jump frame recording module 33, and the standard frame recording module 32 records the real picture at a frame rate of M frames / s; when the dynamic degree does not exceed the standard threshold value, the frame rate setting module 39 sends a signal recorded in the B frame rate mode to the jump frame recording module 33, and the real picture is recorded at a frame rate of N frames / s through the jump frame recording module 33.

[0200] In some embodiments, the monitoring objects and preset standard thresholds of the real environment dynamics monitoring module 37 include the following three situations:

[0201] a. When the real environment dynamics monitoring module 37 detects a person: the standard threshold is 5 km / h, and the real environment dynamics monitoring module 37 monitors the average moving speed of the person within the preset monitoring time period;

[0202] b. When the real environment dynamics monitoring module 37 monitors both non-motor vehicles and non-motor vehicle drivers at the same time: the standard threshold is 25 km / h, and the real environment dynamics monitoring module 37 monitors the average moving speed of the non-motor vehicles within the preset monitoring time period;

[0203] c. When the real environment dynamics monitoring module 37 detects a motor vehicle: the standard threshold is 50 km / h, and the real environment dynamics monitoring module 37 monitors the average moving speed of the motor vehicle within the preset monitoring time period;

[0204] When the dynamic degree of the monitored object in at least one of the above three situations exceeds the standard threshold value in the corresponding situation, the frame rate setting module 39 sends a signal recorded in the A frame rate mode to the skip frame recording module 33, and the standard frame recording module 32 records the real image at a frame rate of M frames / s;

[0205] When none of the above three situations shows that the dynamic degree of the monitored object exceeds the standard threshold value in the corresponding situation, the frame rate setting module 39 sends a signal recorded in the B frame rate mode to the jump frame recording module 33, and the jump frame recording module 33 records the real picture at a frame rate of N frames / s.

[0206] In some embodiments, the storage module 30 stores new video data in a rolling manner according to a three-month storage period and deletes expired video data.

[0207] In other embodiments, when the preset time period is one day, under the 24-hour timekeeping method, the necessity of capturing video images from 0:00 to 7:00 is lower than the necessity of capturing video images from 7:00 to 24:00, and the skip frame recording module 33 captures video images from 0:00 to 7:00 at a frame rate of N frames / s, and the standard frame recording module 32 captures video images from 7:00 to 24:00 at a frame rate of M frames / s.

[0208] As shown in Figure 1, the present application also provides a mobile terminal device 1000, including the aforementioned camera assembly 100. The mobile terminal device 1000 also includes a signal transmitter and a remote control. The remote control is communicatively connected to the signal transmitter, and the signal transmitter is electrically connected to the camera assembly 100.

[0209] In some embodiments, the camera assembly 100 includes a height and azimuth control module 31 electrically connected to the signal transmitter 200. A staff member can send a remote control signal via the remote controller 300 to control the height and azimuth control module 31 via the signal transmitter 200 to adjust the height and azimuth of the camera module 22, thereby controlling the monitoring height and viewing angle of the camera module 22.

[0210] It is understandable that the above is only an example and can be adjusted as needed in actual applications and is not limited here.

[0211] In summary, it can be seen that the present application has the above-mentioned excellent characteristics, which can enhance its performance unprecedented in the past and become a product with great practical value.

[0212] The above description is only a preferred embodiment of the present application and is not intended to limit the present application.
