[0032] Figure 1 A schematic diagram illustrating the structural composition of the mouse and camera combined device 10 provided in this embodiment of the present invention. (Reference) Figure 1 As shown, the combined mouse and camera device 10 includes:

[0033] The first lens module 101 is used to receive visible light in order to perform imaging by the camera;

[0034] The second lens module 102 is used to receive infrared light to perform mouse imaging;

[0035] The circuit board assembly 103 is disposed between the first lens module 101 and the second lens module 102, and is in contact with the first lens module 101 and the second lens module 102 respectively. It is used to perform data calculation based on the visible light received by the first lens module 101 to obtain imaging data for the camera, and to perform data calculation based on the infrared light received by the second lens module 102 to obtain cursor displacement data for the mouse.

[0036] In this embodiment of the invention, the first lens module 101 is a telephoto lens module, which can focus visible light (usually with a built-in infrared filter to filter out infrared rays) to receive external visible light and achieve the imaging function of the camera. The second lens module 102 is a short-focus lens module, which can focus infrared light and receive external infrared light to achieve the imaging function of the mouse. The first lens module 101 and the second lens module 102 do not operate simultaneously. That is, at any given time, the mouse and camera combined device 10 in this embodiment of the invention can only function as either a camera or a mouse. The two functions can be switched arbitrarily according to the user's actual needs.

[0037] In this embodiment, the circuit board assembly 103 can be a PCB (Printed Circuit Board) assembly. The circuit board assembly 103 is disposed between the first lens module 101 and the second lens module 102, and is in contact with both the first and second lens modules 101 and 102 respectively. When the first lens module 101 is working, it performs data calculation and processing based on the visible light received by the first lens module 101 to obtain imaging data for the camera, thereby enabling the camera to perform functions such as shooting and scanning. The circuit board assembly 103 is also used when the second lens module 102 is working to perform data calculation and processing based on the infrared light received by the second lens module 102 to obtain cursor displacement data for the mouse, thereby enabling the mouse to control electronic devices (such as laptops).

[0038] This utility model discloses a mouse and camera combo device, comprising: a first lens module for receiving visible light to perform camera imaging; a second lens module for receiving infrared light to perform mouse imaging; and a circuit board assembly disposed between the first and second lens modules, respectively contacting and connecting to the first and second lens modules, for performing data calculations based on the visible light received by the first lens module to obtain imaging data for the camera, and performing data calculations based on the infrared light received by the second lens module to obtain cursor displacement data for the mouse. This utility model enables switching between mouse and camera functions in a single device, saving manufacturing costs and improving the miniaturization, integration, and convenience of the device.

[0039] In one embodiment, the combined mouse and camera device 10 further includes:

[0040] A photosensitive module 104 is disposed above the circuit board assembly 103 and is at least partially electrically connected to the circuit board assembly 103. It is used to convert visible light received by the first lens module 101 into a first electrical signal, so that the circuit board assembly 103 can perform data calculation based on the first electrical signal to obtain imaging data for the camera; and to convert infrared light received by the second lens module 102 into a second electrical signal, so that the circuit board assembly 103 can perform data calculation based on the second electrical signal to obtain cursor displacement data for the mouse.

[0041] In this embodiment, reference Figure 1As shown, the photosensitive module 104 is at least partially electrically connected to the circuit board assembly 103. The photosensitive module 104 is mainly used to realize photoelectric changes. Specifically, when the first lens module 101 is working, the photosensitive module 104 is used to convert the visible light received by the first lens module 101 into a first electrical signal, so that the circuit board assembly 103 can perform data calculation and processing based on the first electrical signal to realize the relevant functions of the camera. When the second lens module 102 is working, the photosensitive module 104 is used to convert the infrared light received by the second lens module 102 into a second electrical signal, so that the circuit board assembly 103 can perform data calculation and processing based on the second electrical signal to realize the relevant functions of the mouse.

[0042] In one embodiment, the photosensitive module 104 includes a photosensitive film 1041 and a photosensitive substrate 1042; the photosensitive film 1041 is used to receive visible light collected by the first lens module 101 and convert it into a first electrical signal, and to receive infrared light collected by the second lens module 102 and convert it into a second electrical signal.

[0043] The photosensitive substrate 1042 is disposed below the photosensitive film 1041 and is electrically connected to the photosensitive film 1041 to support the photosensitive film 1041 and ensure that the photosensitive film 1041 is placed stably.

[0044] In this embodiment, reference Figure 1 As shown, the photosensitive module 104 includes a photosensitive film 1041 and a photosensitive substrate 1042. The photosensitive film 1041 is used to receive light information (visible light collected by the first lens module 101 or infrared light collected by the second lens module 102) and convert the light information into corresponding electrical signals (a first electrical signal or a second electrical signal). The photosensitive film 1041 can perform electrical signal conversion for both visible light and infrared light in the 1-2µm range. The converted electrical signals from the photosensitive film 1041 are connected to the circuit board assembly 103 via wires and transmitted to the backend for data processing.

[0045] A photosensitive substrate 1042 is disposed below the photosensitive film 1041, electrically connected to the photosensitive film 1041, and electrically connected to the circuit board assembly 103, serving to support the photosensitive film 1041 and ensure its stable placement. The photosensitive substrate 1042 is typically made of single-crystal Si (silicon), which allows light transmission of 1µm or more; that is, the photosensitive substrate 1042 is a substrate through which infrared light can pass but visible light cannot.

[0046] In one embodiment, the photosensitive substrate 1042 is a substrate that transmits infrared light but does not transmit visible light.

[0047] As mentioned above, since the first lens module 101 and the second lens module 102 of the mouse and camera combined device 10 in this embodiment share a single photosensitive module 104, in order to focus the light collected by both the first lens module 101 and the second lens module 102 onto the photosensitive film 1041 of the photosensitive module 104, the photosensitive substrate 1042 in this embodiment needs to be a substrate that allows infrared light to pass through but not visible light. Specifically, refer to... Figure 1 As shown, since the photosensitive film 1041 is disposed on the photosensitive substrate 1042, the visible light collected by the first lens module 101 can be directly focused onto the photosensitive film 1041. Because the photosensitive substrate 1042 is impermeable to visible light, the visible light collected by the first lens module 101 will not pass through the photosensitive substrate 1042, but will be entirely focused onto the photosensitive film 1041, thereby achieving imaging for the camera. The second lens module 102 is located below the entire photosensitive module 104. When the second lens module 102 collects infrared light, because the photosensitive substrate 1042 is permeable to infrared light, the infrared light collected by the second lens module 102 will pass through the photosensitive substrate 1042 and be focused onto the photosensitive film 1041, thereby achieving imaging for the mouse.

[0048] In one embodiment, the first lens module 101 includes a first bracket 1011 and a first focusing lens 1012;

[0049] The first focusing lens 1012 is used to focus visible light;

[0050] The first bracket 1011 is in contact with the first focusing lens 1012 and the circuit board assembly 103 respectively, and is used to fix the first focusing lens 1012 and ensure the stability of the position of the first focusing lens 1012.

[0051] In this embodiment, reference Figure 1 As shown, the first lens module 101 includes a first bracket 1011 and a first focusing lens 1012. The first focusing lens 1012 is mainly used to focus visible light from the outside world. The first bracket 1011 is connected to both sides of the first focusing lens 1012, essentially fixing the first focusing lens 1012 by holding it in place. Furthermore, the bottom end of the first bracket 1011 is connected to the circuit board assembly 103, ensuring the stability of the first focusing lens 1012.

[0052] In one embodiment, the second lens module 102 includes a second bracket 1021 and a second focusing lens 1022;

[0053] The second focusing lens 1022 is used to focus infrared light;

[0054] The second bracket 1021 is connected to the second focusing lens 1022 and the circuit board assembly 103 respectively, and is used to fix the second focusing lens 1022 and ensure the stability of the position of the second focusing lens 1022.

[0055] In this embodiment, reference Figure 1 As shown, the second lens module 102 includes a second bracket 1021 and a second focusing lens 1022. The second focusing lens 1022 is primarily used to focus infrared light from the outside environment. The second bracket 1021 is connected to both sides of the second focusing lens 1022, effectively fixing the second focusing lens 1022 by holding it in place. Furthermore, the bottom end of the second bracket 1021 is connected to the circuit board assembly 103, ensuring the stability of the second focusing lens 1022's position. In addition, in this embodiment, the first bracket 1011 and the second bracket 1021 can also block stray light, preventing it from entering the photosensitive module 104 from other angles.

[0056] In one embodiment, the focal length of the first focusing lens 1012 is greater than the focal length of the second focusing lens 1022.

[0057] In this embodiment, considering the different focal lengths required for imaging by the camera and the mouse, the camera typically senses and captures light beyond 300mm, while the mouse typically senses and captures light reflected from the screen at a near focal length. Therefore, the focal length of the first focusing lens 1012 used for camera imaging is greater than the focal length of the second focusing lens 1022 used for mouse imaging.

[0058] In one embodiment, the circuit board assembly 103 includes a first circuit board 1031, the first circuit board 1031 being provided with a supplementary light source 10311, the supplementary light source 10311 being electrically connected to the first circuit board 1031 and used to supplement the light source for the first lens module 101 or the second lens module 102.

[0059] In this embodiment, reference Figure 1 As shown, the circuit board assembly 103 includes a first circuit board 1031, on which a supplementary light source 10311 is disposed and electrically connected. The supplementary light source 10311 can be an infrared supplementary light source or a visible light supplementary light source. The supplementary light source 10311 is used to supplement the light source for the first lens module 101 or the second lens module 102 when the surrounding environment is relatively dark or the brightness is low, so as to ensure the focusing effect of the first focusing lens 1012 or the second focusing lens 1022.

[0060] In one embodiment, the circuit board assembly 103 includes a second circuit board 1032, the second circuit board 1032 being provided with a control chip 10321, the control chip 10321 being electrically connected to the second circuit board 1032, and being used to control the amount of visible light received by the photosensitive film 1041 for the first lens module 101, and to control the amount of infrared light received by the photosensitive film 1041 for the second lens module 102.

[0061] In this embodiment, reference Figure 1 As shown, the circuit board assembly 103 includes a second circuit board 1032, on which a control chip 10321 is disposed and electrically connected. The control chip 10321 is used to control the amount of visible and infrared light received by the photosensitive film 1041. Specifically, considering the requirements of camera functionality, the photosensitive film 1041 typically contains a large number of pixels; for example, commonly used photosensitive films range from FHD to 2M to 5M, with the number of pixels ranging from 1×10⁶ to 1×10⁸. Mouse functionality typically requires fewer pixels, usually on the order of 50×50. The control chip 10321 can control the acquisition frequency and acquisition range of the photosensitive film 1041. When the user selects mouse mode, the control chip 10321 controls the photosensitive film 1041 to reduce the receiving range of infrared light data acquired by the second lens module 102, reducing the amount of data received each time (e.g., acquiring 50×50 pixels), while significantly increasing the data acquisition frequency (e.g., 100-1000 frames / second), and comparing the images to obtain the relative movement distance to calculate the cursor movement distance, which is then output to the backend. When the user selects camera mode, the control chip 10321 controls the photosensitive film 1041 to perform global scanning (e.g., controlling the acquisition of 1920×1080 pixels), while using a lower acquisition frequency (e.g., 30-60 frames / second) to receive data, and processes and calculates the received data to generate an image output to the backend.

[0062] In one embodiment, the control chip 10321 is further configured to receive a mode command and adjust the first lens module 101 or the second lens module 102 to a closed state based on the mode command, so as to perform imaging by the camera or mouse.

[0063] In this embodiment, the control chip 10321 is also used to receive mode commands. Mode commands are commands issued by the user, and they can represent the user's intended use of a specific function, such as whether the user currently wants to use the mouse or camera function. (See reference...) Figure 2As shown, when the user's mode command indicates that the user wants to use the camera function, the control chip 10321 controls the first lens module 101 to be in the working state and the second lens module 102 to be in the off state, so as to perform camera imaging based on the first lens module 101. When the user's mode command indicates that the user wants to use the mouse function, the control chip 10321 controls the second lens module 102 to be in the working state and the first lens module 101 to be in the off state, so as to perform mouse imaging based on the second lens module 102. Specifically, the mouse and camera combined device 10 in this embodiment may also include a rotatable housing 105. The rotatable housing 105 has a semi-circular structure, with its first end rotatably connected to the first circuit board 1031 and its second end rotatably connected to the second circuit board 1032. When the user selects the mouse function, the control chip 10321 controls the rotatable housing 105 to rotate so that it covers the first lens module 101, as shown in the reference. Figure 3 As shown. When the user selects the camera function mode, the control chip 10321 controls the rotatable housing 105 to rotate so that the second lens module 102 can cover it, as shown in the reference. Figure 4 As shown.
