[0036] Please refer to Figures 1 to 7 This utility model provides a camera device, including: a camera assembly, an assembly assembly, a control assembly, and a communication assembly. The camera assembly includes a first camera 102 and a second camera 103. The assembly assembly includes an assembly plate group, an upper mounting end 106 disposed at the top of the assembly plate group, and a lower mounting end 107 disposed at the bottom of the assembly plate group. The first camera 102 and the second camera 103 are respectively mounted on the upper mounting end 106 and the lower mounting end 107. The camera assembly is electrically connected to the control assembly, and the control assembly is provided with an illumination component for supplementing light to the camera assembly. The communication assembly (not shown in the figure) is used to transmit written content to the communication receiving component. When the first camera 102 is mounted on the upper mounting end 106, its camera surface is tilted downwards, and when the second camera 103 is mounted on the lower mounting end 107, its camera surface is tilted upwards. Furthermore, the camera assembly including the first camera 102 and the second camera 103 can be implemented using two independent camera modules, which are installed in different positions to expand the shooting range.

[0037] The assembly assembly includes an assembly plate group, an upper mounting end 106, and a lower mounting end 107, which can be formed from metal or plastic sheets. The upper mounting end 106 and lower mounting end 107 are located at the top and bottom of the assembly plate group, respectively, and are used to fix the camera. The control component is electrically connected to the camera assembly and can be implemented using a circuit board with an integrated control chip to coordinate camera operation and image processing. The lighting component is mounted on the control component and can be implemented using an LED array to supplement the light source in low light conditions to improve shooting quality. The communication component is used to transmit written content and can be a wireless communication module or data transmission module. The interface is implemented to send the captured content to an external device in real time. The receiving component is the external device. In this embodiment, the writing content can be the writing trajectory captured by the camera component or the data after the control component processes the writing trajectory. When the first camera 102 is installed on the upper mounting end 106, the camera face is tilted downwards. When the second camera 103 is installed on the lower mounting end 107, the camera face is tilted upwards. Specifically, an adjustable angle mounting bracket can be used to cover different areas of the blackboard through complementary angles. In this embodiment, the tilt angle of the first camera 102 and the second camera 103 can be 30°-60°, preferably 45°.

[0038] The key to this solution is the tilted mounting design of the two cameras. By staggering their vertical positions and tilting the camera faces in opposite directions, overlapping coverage of the central area of ​​the blackboard is achieved. This layout captures the entire writing area without requiring dynamic adjustments to the camera angles.

[0039] See Figures 1-7 In this embodiment, the assembly plate group includes a first assembly plate 111 and a second assembly plate 112. The upper mounting end 106 is mounted on the top of the first assembly plate 111, and the lower mounting part is mounted on the bottom of the second assembly plate 112. The upper mounting end 106 includes a first mounting part 113 and a second mounting part 114 disposed above the first mounting part 113. A first inclined plate 115 is disposed on one side of the first mounting part 113, and a first engaging groove 116 is disposed on the first inclined plate 115. A second inclined plate 117 is disposed on the side of the second mounting part 114 near the first mounting part 113, facing the first inclined plate 115. A second engaging groove 118 is disposed on the second inclined plate 117 that is adapted to the first engaging groove 116.

[0040] The lower mounting end 107 includes a third mounting portion 119 and a fourth mounting portion 120 disposed above the third mounting portion 119. A third inclined plate 121 is provided on one side of the third mounting portion 119, and a third engaging groove 122 is provided on the third inclined plate 121. A fourth inclined plate 123 is provided on the side of the fourth mounting portion 120 near the third mounting portion 119, directly opposite the third inclined plate 121. A fourth engaging groove 124, adapted to the third engaging groove 122, is provided on the fourth inclined plate 123. Furthermore, the first mounting portion 113 and the second mounting portion 114 form a clamping structure through the two sets of inclined plates, and the two sets of engaging grooves form a continuous positioning groove, thereby ensuring that the first camera 102 and the second camera 103 are in an inclined state during installation.

[0041] See Figures 1-7 In this embodiment, the second inclined plate 117 is provided with a first engaging limiting plate 125 that cooperates with the first engaging groove 116 and the second engaging groove 118 to engage the first camera 102; the fourth inclined plate 123 is provided with a second engaging limiting plate 126 that cooperates with the third engaging groove 122 and the fourth engaging groove 124 to engage the second camera 103. Furthermore, the first engaging limiting plate 125 is integrally formed with the second inclined plate 117 to form a limiting surface for the mounting plate 127. The second engaging limiting plate 126 adopts the same structure to form a limiting surface for the mounting plate 127.

[0042] Specifically, when the camera mounting plate 127 is inserted into the first engaging slot 116 and the second engaging slot 118, the side of the mounting plate 127 contacts the horizontal edge of the first engaging limiting plate 125, preventing the camera from dislodging from the engaging slot. The camera's connecting cable passes through the first through-hole 131 and extends to the control circuit board 133. The connecting cable of the second camera 103 is fixed through the second through-hole 132, forming a stable connection with the control circuit board 133.

[0043] See Figures 1-7 In this embodiment, both the first camera 102 and the second camera 103 include a mounting plate 127 and a camera body 128 detachably connected to the mounting plate 127. The mounting plate 127 can be snapped into the first engaging groove 116 and the second engaging groove 118. Furthermore, a threaded seat 129 is provided on one side of the mounting plate 127, and an external thread 130 adapted to the threaded seat 129 is provided on the outer side wall of the camera body 128. The camera body 128 and the threaded seat 129 can be threadedly connected by the external thread 130 and the threaded seat 129. The snapping method of the mounting plate 127 and the engaging groove includes, but is not limited to, sliding insertion, elastic buckle, or limiting insertion; the connection method of the camera body 128 and the mounting plate 127 can also adopt magnetic attraction, quick-release buckle, or pin structure.

[0044] Specifically, after the mounting plate 127 snaps into the first engaging slot 116 and the second engaging slot 118, the camera body 128 is fixed by the engagement of the threaded seat 129 and the external thread 130. When disassembly is required, the camera body 128 can be separated by rotating it in the reverse direction, avoiding damage to the assembly components. The snap-fit ​​structure of the mounting plate 127 ensures the overall installation position of the camera is stable, while the detachable design allows for the individual replacement of the camera body 128. For example, if the lens is damaged, only the body can be replaced without disassembling the entire mounting plate.

[0045] See Figures 1-7 In this embodiment, the control component includes a control circuit board 133. A detachable connector is provided on one side of the assembly plate, and the assembly plate is detachably connected to the control circuit board 133 via the detachable connector. Furthermore, a housing 135 is provided on the outer side of the control circuit board 133. The detachable connector includes an internally threaded post 136 disposed on the assembly plate assembly, a first through hole 137 disposed on the control circuit board 133, and a second through hole 138 disposed on the housing 135. The internally threaded post 136 passes through the first through hole 137, and a bolt passes through the second through hole 138. The control circuit board 133 can be connected via the threaded engagement of the bolt with the internally threaded post 136. The circuit board 133 is connected to the assembly board assembly. Specifically, the control circuit board 133 and the assembly board are connected by the threaded connection of the threaded post 136 and the bolt, forming a reliable and repeatedly detachable connection. This facilitates subsequent installation, disassembly and maintenance operations, improving the maintainability of the entire machine. The first through hole 137 and the second through hole 138 cooperate to accurately guide the threaded post, which helps to improve the stability and positioning accuracy of the connection and prevent the circuit board from shifting or loosening during use. The outer shell 135 of the control circuit board 133 can protect the circuit board components and avoid collisions or contamination during assembly and use, thereby improving the overall reliability and service life of the system.

[0046] See Figures 1-7 In this embodiment, a wiring cover 140 is provided on the control circuit board 133. Multiple wires 141 for connecting to external electrical appliances extend from the wiring cover 140. Furthermore, the wiring cover 140 is detachably connected to the surface of the control circuit board 133, and its interior forms a cavity to accommodate the wires 141, with one end extending outward through the side wall of the wiring cover 140. The number of wires 141 is determined according to the requirements of the external electrical interface; for example, three wires 141 may be provided to correspond to power supply, signal transmission, and grounding functions, respectively. The wiring cover 140 is fixed by clips or screws for easy disassembly and maintenance.

[0047] See Figures 1-7In this embodiment, a blackboard is provided, including a camera device. Assembly components are disposed on the left and right sides of the blackboard body 200. A first camera 102 and a second camera 103 are tilted towards the center of the blackboard body 200. Furthermore, the assembly components can be installed on one or both sides of the blackboard, depending on the length of the blackboard. The camera tilt angle is adjusted according to the blackboard width and installation height, with the tilt direction based on the lens optical axis pointing towards the center line of the blackboard. A mounting plate 127 is fixedly connected to the side of the blackboard by bolts. The mounting plate is perpendicular to the blackboard plane. Furthermore, by placing the assembly components on the left and right sides of the blackboard body 200, dust and water contamination of the camera components and assembly components during blackboard use are avoided when the assembly is installed at the bottom of the blackboard.
