[0029] 2. Since the intelligent portrait photographing camera provided by the present utility model only includes components related to the photographing function, it is small in size and light in weight, realizing a lightweight design.

[0030] 3. Since the lens is a fixed-focus manual focus lens, it can be integrally fixedly connected to the lens accommodating cavity, thereby reducing the number of structural parts of the whole camera and facilitating installation.

[0031] 4. By setting a positioning boss on one side of the lens close to the top shell, setting a positioning hole on the positioning boss, and ensuring that the center of the sensor board and the center of the lens are on the same straight line by setting the position of the positioning hole, the sensor board can be fixedly connected to the positioning hole of the positioning boss on one side of the lens close to the top shell by screws, thereby ensuring the consistency of the center of the sensor board and the center of the lens and guaranteeing the image quality of imaging.

[0032] 5. By setting one end of the FPC board electrically connected to the SOC and the other end electrically connected to the sensor board, communication between the SOC and the sensor board is realized.

[0033] 6. By setting a way that the top shell and the bottom shell are fixedly connected to form a rectangular body, the shape of the intelligent portrait photographing camera provided by the embodiment of the present utility model is regular, thus facilitating installation to other devices.

[0034] 7. The intelligent portrait photographing camera provided by the embodiment of the present utility model uses industrial-grade chips instead of consumer-grade chips, which greatly reduces the cost. Moreover, the industrial-grade chips can work stably at -20°C to 70°C, improving the stability of the camera under low temperature, high temperature, and continuous working conditions.

[0035] 8.

In terms of circuit layout, by adding an isolation transformer and an anti-electromagnetic interference circuit to the transmission link, not only can the interference signals on the transmission cable be shielded, but also the surges of external strong electricity can be blocked from cracking the camera-side network port circuit, ensuring that the camera device can stably transmit data in a complex network topology and enhancing the service life of the device.

[0037] 10. Through the HDMI output interface of the camera, it can be directly connected to a video display device with an HDMI standard input interface to intuitively display the preview and photographing screen of the camera.

[0057] It should be noted that the terms "include" and "have" and any variations thereof in the embodiments of the present invention and the accompanying drawings are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but optionally further includes steps or units not listed, or optionally further includes other steps or units inherent to these processes, methods, products or devices.

Fig. 2(a) is a schematic structural diagram of one side of an intelligent portrait photographing camera provided by an embodiment of the present invention. Fig. 2(b) is a schematic structural diagram of another side of an intelligent portrait photographing camera provided by an embodiment of the present invention.

[0060] See Figures 1 - 2(b) , an intelligent portrait photographing camera provided by an embodiment of the present invention includes a top shell 1, a bottom shell 2, a main board 3, a sensor board 4, an FPC (Flexible Printed Circuit) board 5, a lens 6, an SOC (System on Chip), a network interface connector, a power supply interface connector, a USB (Universal Serial Bus) connector, a Micro SD (Secure Digital Memory Card) connector, and an HDMI (High Definition Multimedia Interface) connector. Among them, the materials of the top shell 1 and the bottom shell 2 are both injection-molded parts, thereby reducing the weight of the whole machine.

[0061] Figure 3 It is a cross-sectional view of one side after the top shell 1 and the bottom shell 2 provided by an embodiment of the present invention are fixedly connected. See Figure 3, the top case 1 and the bottom case 2 are fixedly connected to form an accommodation cavity inside. The main board 3, the sensor board 4, the FPC board 5 and the lens 6 are all arranged in the accommodation cavity. Among them, the top case 1 and the bottom case 2 can be fixedly connected by self-tapping screws, and the connection is firm and reliable.

[0062] The SOC, the network interface connector, the power supply interface connector, the USB connector, the MicroSD card connector and the HDMI connector are all fixedly installed on the main board 3 and are all electrically connected to the SOC. When an external device is inserted into different connectors to communicate with the SOC, the conversion of the communication protocol can be realized at the SOC end, or chips corresponding to each interface can also be connected between the SOC and each connector, and the chips are used for the conversion of the communication protocol. This embodiment does not make specific limitations on this.

[0063] And, continue to refer to Figure 1 , a reserved hole is provided on one outer wall of the bottom case 2. An intelligent portrait photography camera provided by an embodiment of the present invention further includes a hot press nut 7. The hot press nut 7 is fixed in the reserved hole by a hot press method. Thus, the entire intelligent portrait photography camera is fixed by the hot press nut 7.

[0064] Continue to refer to Figure 1 , a convex platform is provided on one side of the bottom case 2 close to the top case 1 inside. The main board 3 is fixedly connected to the convex platform.

This embodiment of the present invention does not make any limitations on this.

[0065] A lens accommodation cavity is provided on one side of the bottom case 2 away from the top case 1 inside. The lens 6 is fixedly connected in the lens accommodation cavity. Among them, the lens 6 can be fixedly connected in the lens accommodation cavity by the way that the lens 6 is fixed in the lens accommodation cavity by interference fit and adding glue. The lens 6 is a fixed-focus manual focus lens.

[0066] Since the lens 6 is a fixed-focus manual focus lens, it can be integrally fixedly connected in the lens accommodation cavity, thereby reducing the number of structural parts of the camera as a whole and facilitating installation.

[0067] Continue to refer to Figure 1 , the sensor board 4 is fixedly connected to one side of the lens 6 close to the top case 1. Among them, the sensor board 4 can be fixedly connected to one side of the lens 6 close to the top case 1 by the way that the sensor board 4 is fixedly connected to the positioning hole of the positioning convex platform on one side of the lens 6 close to the top case 1 by screws. Among them, the position of the positioning hole ensures that the center of the sensor board 5 and the center of the lens 6 are on the same straight line.

[0068] Thus, by providing a positioning boss on the side of the lens 6 close to the top case 1, providing a positioning hole on the positioning boss and setting the position of the positioning hole, the center of the sensor board 5 can be made to be in a straight line with the center of the lens 6. In this way, the sensor board 4 can be fixedly connected to the positioning hole of the positioning boss on the side of the lens 6 close to the top case 1 by screws, thereby ensuring the consistency between the center of the sensor board 5 and the center of the lens 6 and guaranteeing the imaging quality.

[0069] One end of the FPC board 5 is electrically connected to the SOC on the main board 3, and the other end is electrically connected to the sensor board 5. Among them, the electrical connection manner between the FPC board 5, the SOC and the sensor 5 can be any one of the electrical connection manners of the FPC board 5 in the prior art, and the embodiments of the present utility model do not make any limitation thereto.

[0070] Thus, by providing one end of the FPC board 5 to be electrically connected to the SOC and the other end to be electrically connected to the sensor board 5, communication between the SOC and the sensor board 5 is realized.

[0071] Continuing to refer to Fig. 2(a), an external interface 8 of a network interface connector and an external interface of a power supply interface connector 9 are provided on one outer wall of the top case 1, and an external interface 10 of a USB connector, a card slot 11 of a Micro SD card connector and an external interface 12 of an HDMI connector are provided on the other outer wall.

[0072] Among them, the network interface connector is used for real-time transmission of network port video streams; the power supply interface connector is used for power supply and serial communication, and the user can control the camera to take pictures through the serial port; the USB connector is used for communication and data transmission with the host computer; the Micro SD card connector is used for installing a Micro SD card to store the pictures taken by the camera; and the HDMI connector is used for connecting to peripheral devices such as a display and outputting video streams.

[0073] In summary, an intelligent portrait photographing camera provided by an embodiment of the present utility model includes a top shell 1, a bottom shell 2, a main board 3, a sensor board 4, an FPC board 5, a lens 6, a system-on-chip SOC, a network interface connector, a power supply interface connector, a universal serial bus USB connector, a Micro Secure Digital Card SD card connector, and a High-Definition Multimedia Interface HDMI connector. Among them, the materials of the top shell 1 and the bottom shell 2 are both injection-molded parts. The top shell 1 and the bottom shell 2 are fixedly connected to form an accommodation cavity inside. The main board 3, the sensor board 4, the FPC board 5, and the lens 6 are all arranged in the accommodation cavity. The SOC, the network interface connector, the power supply interface connector, the USB connector, the MicroSD card connector, and the HDMI connector are all fixedly installed on the main board 3 and are all electrically connected to the SOC. A boss is provided on one side of the inside of the bottom shell 2 close to the top shell 1, and the main board 3 is fixedly connected to the boss. A lens accommodation cavity is provided on one side of the inside of the bottom shell 2 away from the top shell 1, and the lens 6 is fixedly connected in the lens accommodation cavity. The sensor board 4 is fixedly connected to one side of the lens 6 close to the top shell 1. One end of the FPC board 5 is electrically connected to the SOC, and the other end is electrically connected to the sensor board 5. Among them, the center of the sensor board 5 and the center of the lens 6 are on the same straight line. The lens 6 is a fixed-focus manual focusing lens. An external interface 8 of the network interface connector and an external interface 9 of the power supply interface connector are provided on the outer wall of one side of the top shell 1, and a peripheral interface 10 of the USB connector, a card slot 11 of the MicroSD card connector, and an external interface 12 of the HDMI connector are provided on the outer wall of the other side. Since the intelligent portrait photographing camera provided by the present utility model includes the top shell 1, the bottom shell 2, the main board 3, the sensor board 4, the FPC board 5, the lens 6, the main control chip SOC, the network interface connector, the power supply interface connector, the universal serial bus USB connector, the Micro Secure Digital Card SD card connector, and the High-Definition Multimedia Interface HDMI connector, it can be seen that the intelligent portrait photographing camera provided by the present utility model only includes devices related to the photographing function, and the materials of the top shell 1 and the bottom shell 2 are both injection-molded parts. Therefore, the cost can be reduced. Moreover, the lens 6 is a fixed-focus manual focusing lens, which can ensure that the focus does not change after focusing. In addition, the external interface 8 of the network interface connector, the external interface 9 of the power supply interface connector, the external interface 10 of the USB connector, the card slot 11 of the Micro SD card connector, and the external interface 12 of the HDMI connector are provided, and the interfaces are rich, which can provide multiple transmission paths.

[0074] Moreover, since the intelligent portrait photographing camera provided by the present utility model only includes devices related to the photographing function, it is small in volume and light in weight, realizing a lightweight design.

[0075] In one implementation, the top shell 1 and the bottom shell 2 form a rectangular body after being fixedly connected, as Figure 4 shown Figure 4This is a schematic structural diagram of an intelligent portrait photography camera provided by an embodiment of the present invention from a certain angle.

[0076] Thus, by setting the top case 1 and the bottom case 2 to be fixedly connected to form a rectangular body, the shape of the intelligent portrait photography camera provided by the embodiment of the present invention is regular, thereby facilitating installation to other devices.

[0077] In another implementation manner, the intelligent portrait photography camera provided by the embodiment of the present invention further includes an industrial-grade chip, and the industrial-grade chip is fixedly installed on the main board 3. Among them, the industrial-grade chip can be fixedly installed on the main board 3 in any fixed connection manner in the prior art, and the embodiment of the present invention does not make any limitation thereto. For the introduction of the industrial chip, refer to the following text.

[0078] Thus, the intelligent portrait photography camera provided by the embodiment of the present invention uses an industrial-grade chip instead of a consumer-grade chip, greatly reducing the cost. Moreover, the industrial-grade chip can work stably at -20°C - 70°C, improving the stability of the camera under low temperature, high temperature, and continuous working conditions.

[0079] Figure 5 This is the schematic diagram of the main board interface function provided by the embodiment of the present invention. Each connector is arranged on the main board and has a connection relationship with the SOC. This connection relationship can be directly connected to the SOC or indirectly connected through other chips. Alternatively, each connector can also be arranged at other positions inside the camera according to actual situations, and the present embodiment does not make specific limitations thereto.

[0080] In this embodiment, in order to utilize each interface to implement the corresponding communication function, a plurality of industrial-grade chips are installed on the camera main board, such as one or more of a peripheral insertion direction selection chip, a signal channel switching chip, a network signal conversion chip, and a storage chip, etc. Next, the connection relationship and functions between each multifunctional interface and its corresponding industrial-grade chip will be introduced respectively.

[0081] (1) Regarding the peripheral insertion direction selection chip and the signal channel switching chip

[0082] Figure 6 This is the principle structure diagram of the USB function implementation provided by the embodiment of the present invention. As Figure 6 shown, among them, the signal input terminals of the signal channel switching chip 210 are respectively connected to the signal output terminals of the SOC 220 and the peripheral insertion direction selection chip 230, the signal output terminal of the signal channel switching chip 220 is connected to the USB connector 240, and the signal input terminal of the peripheral insertion direction selection chip 230 is connected to the USB connector 240, where

[0083] The USB connector 240 is used to output a level signal corresponding to the insertion direction of the external device after the external device is inserted, and output the level signal to the peripheral insertion direction selection chip 230. Here, the insertion direction can be forward insertion or reverse insertion;

[0084] The peripheral insertion direction selection chip 230 is used to generate a channel selection signal according to the received level signal;

[0085] The signal channel switching chip 210 is used to receive the communication interface signal output by the SOC 220, switch the signal channel according to the channel selection signal output by the peripheral insertion direction selection chip 230, and output the communication interface signal to the USB connector 240 based on the switched signal channel for data exchange with the external device.

[0086] In this embodiment, the internal circuit structures of the peripheral insertion direction selection chip and the signal channel switching chip can be designed according to the USB communication functions to be implemented. Specifically, Figure 7 is the circuit schematic diagram of the signal channel switching chip provided by the embodiment of the present utility model, Figure 8 is the circuit schematic diagram of the peripheral insertion direction selection chip provided by the embodiment of the present utility model, Figure 9 is the circuit schematic diagram of the USB connector provided by the embodiment of the present utility model. As Figures 7 - 9 shown, the USB connector has two groups of pins respectively connected to the external device, including the first group of pins (pins A10, A11, B10, and B11), and the second group of pins (pins A2, A3, B2, and B3). These two groups of pins respectively correspond to the insertion direction of the external device (including forward insertion or reverse insertion). That is, during the communication with the external device, only one group of pins is activated to communicate with the external device each time. For example, when the external device is inserted forward, the first group of pins is activated to communicate with the external device; when the external device is inserted reversely, the second group of pins is activated to communicate with the external device. In this embodiment, after the external device is inserted into the USB connector, the USB connector will output different high and low level signals according to different insertion directions. For example, Figure 9 the high and low levels of the CC1 and CC2 signals output by the A5 and B5 pins can reflect the insertion direction of the external device. Figure 9 The CC1 and CC2 signals output by the A5 and B5 pins are transmitted to Figure 8 the 1 and 2 pins of the peripheral insertion direction selection chip shown. The 11 pin of the peripheral insertion direction selection chip will output a channel selection signal indicating the insertion direction of the peripheral device, and this channel selection signal is transmitted to Figure 7Pin 9 of the signal channel switching chip shown. After receiving the channel selection signal, the signal channel switching chip will switch its internal switch, thereby switching the signal channel to adapt to the insertion direction of the peripheral device. Among them, the signal channel switching chip also includes two groups of pins, including the first group of pins (pins 12, 13, 16, and 17) and the second group of pins (pins 14, 15, 18, and 19), and these two groups of pins are respectively connected to the first group of pins and the second group of pins of the USB connector. When an external device is inserted, the SOC outputs a communication interface signal to the signal input pins (pins 4, 3, 8, 7) of the signal channel switching chip. The signal channel switching chip switches the signal channel to a channel that adapts to the insertion direction of the external device, and outputs the received communication interface signal to the USB connector through the switched signal channel for data exchange with the external device. For example, if the external device is inserted forward, data exchange is performed with the external device through the first group of pins; if the external device is inserted backward, data exchange is performed with the external device through the second group of pins.
