Description

Technical Field

[0001] This application relates to the field of information technology, and particularly to a wireless electronic device, an antenna adjustment method and device. Background Art

[0002] With the continuous improvement of technology, the scenarios where cameras are used are increasing, and the environments where cameras need to be installed are becoming more and more complex. In particular, for sparsely populated areas such as deserts, river channels or fields, cameras may also be required to be set up. At this time, if wireless communication is required for the cameras, wireless cameras are usually selected. The wireless camera is powered by solar energy and communicates through wireless communication, so as to facilitate the installation of cameras in sparsely populated areas.

[0003] During the installation and use of a wireless camera, it is necessary to orient the microwave antenna of the wireless camera towards a set direction to communicate with an upstream wireless access point. In the prior art, the wireless camera adopts the method of manual installation and direction adjustment, and it is necessary to manually align the microwave antenna of the wireless camera with the wireless access point to realize the communication between the wireless camera and the backend server. The installation and debugging are difficult and time-consuming. Summary of the Invention

[0004] This application provides a wireless electronic device, an antenna adjustment method and device, so that the antenna adjusts its orientation under the control of a controller, ensuring the signal strength of the wireless electronic device for signal transmission and reception, and improving the speed and quality of wireless communication of the wireless electronic device.

[0005] In a first aspect, the present application provides a wireless electronic device, which includes an antenna device and a functional device connected to the antenna device. Among them, the antenna device is used to implement wireless communication, and the functional device is communicatively connected to the antenna device so that the functional device has the function of wireless communication. Specifically, the antenna device includes a first housing, and an antenna, a transceiver, a driving component, and a controller disposed in the first housing. Among them, the transceiver is used to transmit and receive signals through the antenna, the driving component is used to drive the antenna to rotate, and the controller is used to drive the antenna to rotate by controlling the driving component according to the intensity of the signals received by the transceiver, so that the intensity of the signals received by the transceiver is within a set range. Specifically, during the process of the driving component driving the antenna to rotate, due to the antenna facing the base station or the antenna moving away from the base station, the intensity of the signals received by the transceiver is different. Therefore, the controller controls the driving component to drive the antenna to rotate. When the antenna faces the base station direction, the intensity of the signals received by the transceiver is relatively large, and the intensity of the signals is within the set range. The antenna device can have a better communication effect, and the controller controls the driving component to stop driving the antenna to rotate so that the antenna maintains its current orientation. The wireless electronic device in the present application can adjust the orientation of the antenna under the control of the controller, ensure the intensity of the signals transmitted and received by the wireless electronic device, and improve the wireless communication speed and quality of the wireless electronic device. This solution replaces the method of manually adjusting the antenna orientation by adjusting the mounting bracket in the prior art, reduces the installation and debugging difficulty of the wireless electronic device, and saves labor costs.

[0006] In a specific technical solution, the above-mentioned controller can be electrically connected to the transceiver. The controller monitors the intensity of the signals received by the transceiver, compares the monitored intensity of the signals received by the transceiver with the set range. If the intensity of the signals received by the receiver is outside the set range, it controls the driving component to drive the antenna to rotate; when the intensity of the signals received by the receiver is within the set range, the controller controls the driving component to stop driving the antenna to rotate so that the antenna device can reliably transmit and receive signals. The above-mentioned controller can be electrically connected to the driving component to facilitate controlling the driving component to rotate or stop rotating.

[0007] The specific type of the above-mentioned wireless electronic device is not limited. Specifically, a wireless electronic device can be a wireless camera. In this case, the functional device of the wireless electronic device is a camera device, which can utilize the wireless communication function of the wireless module to realize the transmission of the picture signal. The camera device is detachably connected to the antenna device, so as to select whether to install or not install the antenna device according to requirements. The camera device includes a second housing and a camera assembly disposed in the second housing. The second housing has a sealed cavity to make the camera assembly in a sealed environment, ensuring that the camera assembly can work properly. In this solution, the camera device and the antenna device are independent individuals respectively, so the sealing requirement of the camera device has no influence on the antenna device, which is beneficial to simplifying the assembly and maintenance process of the antenna device. In addition, the camera assembly is communicatively connected to the antenna device, so the image obtained by the camera assembly can be transmitted by using the antenna device. The present application can adjust the orientation of the antenna by using a controller, ensuring the reliability of the image transmission of the wireless camera and being beneficial to improving the speed of the image transmission of the wireless camera and the quality of the transmitted image.

[0008] The above-mentioned wireless camera can specifically be a microwave camera, that is, the antenna receives and transmits signals through microwaves and is applied to areas with sparse population and vast land. For areas with sparse population and vast land, the distance between the wireless camera and the base station is relatively far, which is not conducive to manually adjusting the antenna orientation of the antenna device by adjusting the bracket. And when the antenna needs to be adjusted in orientation, it is not convenient for the operator to go to the site for maintenance. The wireless camera provided by the present application can automatically control the orientation of the antenna by using a controller. On the one hand, it reduces the manual consumption. On the other hand, it can timely adjust the orientation of the antenna, ensuring the strength of the signal received and transmitted by the antenna device and improving the reliability of the antenna in receiving and transmitting signals.

[0009] The way of the detachable connection between the antenna device and the camera device is not limited. For example, the antenna device can be directly detachably connected to the camera device, that is, the first housing is detachably connected to the second housing. Or, the detachable connection between the antenna device and the camera device can also be realized through an adapter. Specifically, one end of the adapter is detachably connected to the antenna device, and the other end of the adapter is detachably connected to the camera device. This solution can make the structure relatively simple when the antenna device and the camera device are independent individuals.

[0010] The above-mentioned wireless electronic device can also be a vehicle-mounted wireless electronic device, which is installed in the car. As the car runs, the vehicle-mounted wireless electronic device will change direction, and the direction of the antenna will also change accordingly, which will have a certain impact on the signal strength received by the transceiver. In the technical solution of this application. The antenna device in the vehicle-mounted wireless electronic device includes a controller. The controller can drive the antenna to rotate by controlling the driving component according to the strength of the signal received by the transceiver, so that the strength of the signal received by the transceiver is within a set range. The wireless communication capability of the vehicle-mounted wireless electronic device is less affected by the direction of the vehicle and can be maintained at a good level.

[0011] The wireless electronic device may further include a solar power supply device, which is used to power the wireless electronic device. In this solution, the power supply and signal transmission of the wireless electronic device can be achieved wirelessly, so the location where the wireless electronic device is installed is not limited by the line setting, which can enrich the application scenarios of the wireless electronic device.

[0012] In order to reduce the energy consumption of the wireless electronic device, the controller of the antenna device is also used to control the driving component to cut off the power after the driving component stops driving the antenna to rotate. When the antenna stops rotating, the driving component no longer needs to work, so it can be in a power-off standby state. When the driving component needs to be started, the controller can also control the driving component to be powered on so that the driving component can drive the antenna to rotate. This solution reduces the energy consumption of the wireless electronic device, so the specifications and performance of the power supply device of the wireless electronic device can be designed to be smaller, which is conducive to reducing the cost of the wireless electronic device.

[0013] When the above-mentioned drive assembly is specifically set, the drive assembly may include a motor and a gear set connected to the motor in a transmission manner. The gear set can reduce the rotation speed of the motor output so that the antenna rotates at a slower speed, which is conducive to determining the direction of the antenna when the strength of the signal received by the transceiver is relatively large. The transmission ratio of the above-mentioned gear set is not less than 50:1. If the transmission ratio is relatively large, when the antenna stops rotating, the gear set can form a self-locking structure to fix the antenna in the current position and is not easily disturbed by vibration, so as to ensure the quality of the signal received by the transceiver through the antenna.

[0014] In order to achieve the purpose of transmitting and receiving signals, the antenna device needs to be provided with a circuit board. The transceiver and the controller can be electrically connected through the circuit board. The circuit board is provided with a heating device. In order to improve the performance of the antenna device, it is necessary to improve the heat dissipation effect of the heating device of the circuit board. The first shell includes a metal base and a plastic cover. The above-mentioned circuit board is installed on the metal base, and the area of ​​the circuit board provided with the heating device is connected to the metal base by heat conduction. The metal base has good thermal conductivity, so that the heating device of the circuit board can conduct heat to the outside, so as to improve the heat dissipation effect of the heating device and increase the service life of the heating device.

[0015] In order to connect the circuit board and the metal base by heat conduction, a first heat conducting layer can be set between the circuit board and the metal base. The first heat conducting layer can be a heat conducting material such as heat conducting glue or heat conducting foam, which has both thermal conductivity and elasticity, which is beneficial to increase the contact area between the heat sink and the metal base and improve the heat dissipation effect.

[0016] The metal base may further include a boss, which faces the circuit board and is connected to a region of the circuit board where a heating device is provided by heat conduction. By providing the boss on the metal base, the reliability of the heat conduction connection between the metal base and the circuit board can be improved.

[0017] In order to improve the heat dissipation effect of the heating device of the circuit board, the antenna module can also be provided with a heat sink, which is arranged on the side of the circuit board away from the metal base, and the heat sink and the circuit board are at least connected in a region where the heating device is arranged by heat conduction. Both sides of the circuit board where the heating device is arranged have heat dissipation structures, so that the heat dissipation effect is better, and a high-power heating device can be arranged to improve the performance of the antenna module. There can also be a second heat-conducting layer between the heat sink and the circuit board. For example, the second heat-conducting layer can also be a heat-conducting glue or a heat-conducting foam.

[0018] When the heat sink is specifically arranged, the edge of the heat sink can be connected to the metal base by heat conduction, and the heat sink can conduct the heat of the heating device to the metal base, and the metal base then conducts the heat to the outside, so as to improve the heat dissipation effect of the antenna module. Specifically, a third heat conduction layer can be arranged between the heat sink and the metal base, for example, it can also be a heat conductive glue or a heat conductive foam.

[0019] The antenna module may further include a wire blocking plate, which is disposed between the circuit board and the antenna to prevent the wires connected to the circuit board from moving to the area where the antenna is located, thereby preventing the antenna from rotating.

[0020] In a specific technical solution, the wire blocking plate and the heat dissipation plate may be an integrated structure to simplify the structure of the antenna module.

[0021] In a second aspect, the present application provides an antenna adjustment method for a wireless electronic device, the method comprising:

[0022] Get the strength of wireless signals;

[0023] When the strength of the wireless signal is less than a preset threshold, the antenna is driven to rotate to obtain a signal that meets the preset threshold strength;

[0024] When the strength of the wireless signal is greater than a preset threshold, the driving of the antenna to rotate is stopped, and the image signal acquired by the camera device is transmitted through the antenna.

[0025] This method can be used to electrically adjust the antenna of a wireless electronic device, so that the intensity of the signal received by the antenna of the wireless electronic device is greater than a preset threshold intensity, to ensure the wireless communication effect of the wireless electronic device. This solution replaces the method of manually adjusting the antenna orientation by adjusting the mounting bracket in the prior art, reduces the difficulty of installation and debugging of the wireless electronic device, and saves labor costs. The specific method for obtaining the intensity of the wireless signal is not limited. Specifically, the intensity of the wireless signal can be monitored manually, and the relationship between the intensity of the wireless signal and the preset threshold can be judged manually to control the driving of the antenna to rotate or stop driving the antenna to rotate.

[0026] In a specific technical solution, the driving of the antenna to rotate and the stopping of the driving of the antenna to rotate can be manually operated. For example, the driving of the antenna to rotate or stop driving the antenna to rotate can be controlled manually by using an operation panel or an operation disk. Alternatively, the controller can also automatically drive or stop driving the antenna to rotate according to the monitored intensity of the wireless signal. This solution can automatically adjust the orientation of the antenna and improve the automation degree of adjusting the antenna orientation of the wireless electronic device. In addition, at any time, when the intensity of the wireless signal is less than the preset threshold, the antenna can be driven to rotate so that the intensity of the wireless signal is greater than the preset threshold, ensuring the quality of wireless communication of the wireless electronic device.

[0027] In one technical solution, after stopping driving the antenna to rotate, the driving component can also be controlled to cut off the power supply to reduce the energy consumption of the wireless electronic device and improve the service life and reliability of the wireless electronic device.

[0028] The type of signal that the above antenna can receive is not specifically limited. For example, the antenna can receive and transmit wireless signals through microwaves, and the received and transmitted wireless signals are microwave signals.

[0029] The above camera device can specifically be a monitoring camera device, especially a monitoring camera device that transmits wireless signals using microwaves. The transmission distance of microwave signals is relatively far. Therefore, when the wireless electronic device is a wireless camera device, it can be installed in areas with sparse population. In this scenario, adopting this solution can more conveniently adjust the orientation of the antenna, improve the wireless communication ability of the wireless electronic device, and improve the transmission speed and quality of the images transmitted and acquired by the wireless camera device.

[0030] In addition, the above monitoring camera device can also be a camera device powered by solar energy. Thus, neither power supply nor signal transmission of this camera device needs to set up wires, and it can fully achieve wireless operation, thereby enriching the application scenarios of wireless electronic devices.

[0031] In addition, the above wireless electronic device can also be a vehicle-mounted wireless electronic device. The vehicle-mounted wireless electronic device is set in a mobile device. When the vehicle-mounted wireless electronic device changes direction along with the vehicle it depends on, the antenna is driven to rotate to obtain a signal with an intensity greater than the preset threshold.

[0032] By adopting the antenna adjustment method in the embodiment of the present application, the antenna can be driven to rotate at any time according to the intensity of the acquired wireless signal, so as to adjust the orientation of the antenna, so that the intensity of the signal received by the antenna is maintained at a level greater than the preset threshold, and the in-vehicle wireless electronic device can maintain a good communication effect. In a specific embodiment, the in-vehicle wireless electronic device may also be the wireless camera in the above embodiment, that is, the in-vehicle wireless camera.

[0033] In a third aspect, the present application further provides an antenna adjustment device for a wireless electronic device. The antenna adjustment device includes each unit for implementing the antenna adjustment method in the second aspect above, specifically including an acquisition unit and a control unit, where:

[0034] The acquisition unit is used to acquire the intensity of the wireless signal; the control unit is used to drive the antenna to rotate to acquire a signal with a strength satisfying the preset threshold when the intensity of the wireless signal is less than the preset threshold; when the intensity of the wireless signal is greater than the preset threshold, stop driving the antenna to rotate, and transmit the image signal acquired by the imaging device through the antenna.

[0035] By using this device, the antenna of the wireless electronic device can be electrically adjusted, so that the intensity of the signal received by the antenna of the wireless electronic device is greater than the preset threshold intensity, so as to ensure the wireless communication effect of the wireless electronic device. This solution replaces the method of manually adjusting the antenna orientation by adjusting the mounting bracket in the prior art, reduces the difficulty of installation and debugging of the wireless electronic device, and saves labor costs.

[0036] There is no limitation on the specific manner in which the above acquisition unit acquires the intensity of the wireless signal. Specifically, the intensity of the wireless signal can be monitored manually, and the relationship between the intensity of the wireless signal and the preset threshold can be judged manually to control the driving of the antenna to rotate or stop driving the antenna to rotate. Alternatively, the intensity of the wireless signal can also be automatically monitored to acquire the intensity of the wireless signal, and the acquired intensity of the wireless signal is compared with the preset threshold to drive or stop driving the antenna to rotate. This solution can automatically adjust the orientation of the antenna and improve the automation degree of the wireless electronic device in adjusting the antenna orientation. In addition, at any time, when the intensity of the wireless signal is less than the preset threshold, the antenna can be driven to rotate so that the intensity of the wireless signal is greater than the preset threshold, ensuring the quality of the wireless communication of the wireless electronic device.

[0037] In a fourth aspect, the present application provides a chip. The chip is installed in the above wireless electronic device and can implement the method in any of the above technical solutions. For example, the chip can monitor the intensity of the wireless signal received by the antenna, perform corresponding calculations, and then generate a driving signal to drive the antenna to rotate or stop driving the antenna to rotate.

[0038] Based on the implementation manners provided in the above aspects of the present application, further combinations can be made to provide more implementation manners. Description of the Drawings

[0069] In order to make the objectives, technical solutions and advantages of this application clearer, the following will further describe this application in detail with reference to the accompanying drawings.

[0070] To facilitate the understanding of the wireless electronic device, antenna adjustment method and device provided in the embodiments of this application, the following first introduces its application scenarios.

[0071] The wireless electronic device provided in the embodiments of this application can be any electronic device that needs to implement wireless communication. Figure 1 For a structural schematic diagram of the wireless electronic device in the embodiments of this application, please refer to Figure 1, the wireless electronic device includes an antenna device 1 and a functional device 2. Among them, the antenna device 1 is used to implement wireless communication, and the functional device 2 is communicatively connected to the antenna device 1 so that the functional device 2 has the function of wireless communication. The above-mentioned functional device 2 can specifically be a camera device 20. Then, the wireless electronic device of this application is a wireless camera, and this wireless camera can use the antenna device 1 to implement wireless communication. The wireless camera can specifically be a microwave camera, that is, the antenna 12 in the antenna device 1 is used to receive microwave signals, which are usually applied to sparsely populated areas such as deserts, river channels, or fields. It is not easy to lay lines in the above areas. Therefore, wireless cameras are usually set up to achieve long-distance communication using wireless cameras and to supply power using solar energy. During the use of the above wireless camera, it is necessary to cooperate the camera device 20 with the antenna 12 to achieve the wireless communication of the camera device 20 and wirelessly transmit the images obtained by the camera device 20.

[0072] In another embodiment, the above wireless electronic device can also be a vehicle-mounted wireless electronic device. It should be noted that the vehicle-mounted wireless electronic device here refers to a wireless electronic device installed on a mobile device, such as any moving equipment such as a vehicle, an aircraft such as a drone, etc., rather than simply referring to a wireless electronic device installed on a vehicle. Since the mobile device often needs to change directions during movement, as the vehicle-mounted wireless electronic device changes directions, the controller 120 of the antenna device 1 in the embodiment of this application can control the antenna 12 to rotate so that the intensity of the signal received by the transceiver 130 of the antenna device 1 is within a set range, so as to keep the vehicle-mounted wireless electronic device in good communication and improve the communication effect of the vehicle-mounted wireless electronic device. The vehicle-mounted wireless electronic device applied in a vehicle can specifically also be a vehicle-mounted camera, or any electronic device that needs to communicate. This application does not make any restrictions.

[0073] Please continue to refer to Figure 1, the electronic device in the embodiment of the present application includes an antenna device 1 and a functional device 2. Among them, the antenna device 1 includes a first housing 11, and an antenna 12, a transceiver 130, a driving component 110, and a controller 120 disposed in the first housing 11. Among them, the transceiver 130 transmits and receives signals through the antenna 12 to implement the communication function of the antenna device 1. The driving component 110 controls the rotation of the antenna 12 under the control of the controller 120. Specifically, the controller 120 controls the driving component 110 to drive the antenna 12 to rotate according to the intensity of the signal received by the transceiver 130, so that the intensity of the signal received by the transceiver 130 is within a set range. The wireless electronic device in this solution can use the controller 120 to control the driving component 110 to drive the antenna 12 to rotate, align the antenna 12 with the base station, ensure that the intensity of the signal received by the transceiver 130 meets the preset requirements, and implement the communication function of the wireless camera. This solution replaces the method of manually adjusting the antenna orientation by adjusting the mounting bracket in the prior art, reduces the installation and debugging difficulty of the wireless electronic device, and saves labor costs.

[0074] In a specific embodiment, the above-mentioned controller 120 is electrically connected to the transceiver 130 and the driving component 110 respectively. The controller 120 monitors the intensity of the signal received by the transceiver 130, and thus controls the driving component 110 according to the monitored intensity of the signal received by the transceiver 130, so that the driving component 110 drives the antenna 12 to rotate, and when the intensity of the signal received by the transceiver 130 is within the set range, the driving component 110 stops driving the antenna 12 to rotate. This solution can automatically control the driving component 110 to act through the controller 120 after installing the wireless camera, improving the automation degree of the wireless camera. Keeping the intensity of the signal received by the transceiver 130 within the set range can ensure the wireless communication effect of the wireless camera, realize the timely and effective transmission of the picture captured by the wireless camera, and ensure the quality of the picture captured by the wireless camera.

[0075] When realizing the detachable connection between the antenna device 1 and the functional device 2, the specific connection method is not limited. For example, it can be a threaded connection, a snap connection, or a clamping connection. When connecting the functional device 2 to the transceiver 130 of the antenna device 1, a connector can be selected for easy installation and disassembly, or it can also be a bare wire connection.

[0076] For the convenience of description, in the following embodiments, the wireless electronic device is taken as an example of a wireless camera to illustrate various possible implementation manners of the wireless electronic device in the embodiments of the present application.

[0077] Figure 2A structural schematic diagram of a wireless camera in an embodiment of the present application is shown in the figure. The wireless camera includes an antenna device 1 and a camera device 20. Among them, the antenna device 1 includes a first housing 11, and an antenna 12 and a circuit board 13 disposed in the cavity of the first housing 11. The above circuit board 13 is provided with electronic devices 14, and the antenna 12 is electrically connected to the circuit board 13. When specifically realizing the electrical connection between the antenna 12 and the circuit board 13, a wire can be used to connect the antenna 12 and the circuit board 13. The wire has a certain length so that it can adapt to the rotation of the antenna when the antenna 12 adjusts its orientation. The camera device 20 includes a second housing 21, and a camera module 22 disposed in the second housing 21. The above second housing 21 has a sealed cavity, and the camera module 22 is disposed in the sealed cavity of the second housing 21. The antenna device 1 is detachably connected to the camera device 20, and the antenna device 1 has a first connector 15, and the camera device 20 has a second connector 23. When the antenna device 1 is connected to the camera device 20, the first connector 15 can be connected to the second connector 23 to realize communication between the camera device 20 and the antenna device 1. Specifically, the above first connector 15 and second connector 23 can be connectors, and electrical connection can be achieved by plugging. Or, bare wire butt-joint can also be used. The present application does not make specific limitations.

[0078] Figure 3 A structural schematic diagram of a wireless camera in the prior art is as Figure 3 shown. In the prior art, a wireless camera includes a housing 01, a camera module 02, and an antenna module 03. Among them, the antenna module 03 includes an antenna 031 and a circuit board 032 connected to the antenna 031. The above circuit board 032 and the camera module 02 are disposed in the housing 01, and the antenna 031 is disposed outside the housing 01. Since the camera module 02 needs to work in a sealed environment, the inner cavity of the housing 01 is a sealed inner cavity. For example, the inner cavity of the housing 01 meets the IP66 level of protection. In this solution, since the housing 01 needs to maintain airtightness, the manufacturing process of the wireless camera is relatively complicated and not convenient for maintenance.

[0079] In the technical solution of this application, the antenna device 1 and the imaging device 20 respectively have a first housing 11 and a second housing 21, which are two relatively independent structures. Therefore, the airtightness requirement of the imaging device 20 has no influence on the antenna device 1. When in use, the user can configure the antenna device 1 according to needs. In addition, the imaging device 20 and the antenna device 1 can be used separately as independent individuals. When the antenna device 1 is not needed, the imaging device 20 can be used as a wired camera. When the user needs to use a wireless camera, the antenna device 1 can be configured on the existing imaging device 20 to form a wireless camera. Thus, the functions of the camera are enriched, and a suitable camera can be configured according to needs, which is beneficial to cost reduction. In addition, in the embodiment of this application, installing the antenna 12 into the antenna device 1 can also protect the antenna 12 and extend the service life of the antenna 12.

[0080] Please continue to refer to Figure 2 , the wireless camera further includes an adapter bracket 3. The above-mentioned antenna device 1 and imaging device 20 are respectively installed at both ends of the adapter bracket 3 to achieve a detachable connection between the antenna device 1 and the imaging device 20. That is to say, the antenna device 1 is detachably connected to one end of the adapter bracket 3, and the imaging device 20 is detachably connected to the other end of the adapter bracket 3. In addition, by connecting the first connector 15 and the second connector 23, the assembly of the imaging device 20 and the antenna device 1 can be realized to form a wireless camera. In this solution, by providing the adapter bracket 3, it is beneficial to simplify the connection structure between the antenna device 1 and the imaging device 20. Thus, when the antenna device 1 and the imaging device 20 are independent individuals, the structure is relatively simple. Of course, in other embodiments, the wireless camera may not include the adapter bracket 3, and the imaging device 20 and the antenna device 1 can be directly detachably connected.

[0081] When specifically realizing the detachable connection between the antenna device 1 and the adapter bracket, the detachable connection between the imaging device 20 and the adapter bracket, or the detachable connection between the antenna device 1 and the imaging device 20, the two detachable connection structures can be threadedly connected, screwed, clamped or clamped. This application does not make any restrictions.

[0082] Please continue to refer to Figure 2 , the wireless camera may further include an outer housing 4. The outer housing 4 is formed with a receiving cavity. After the antenna device 1 and the imaging device 20 are assembled, they can be installed in the receiving cavity of the outer housing 4. The outer housing 4 can protect the structures of the imaging device 20, the antenna device 1 and the connection area, improve the reliability of the wireless camera, and in addition, can also improve the integrity of the wireless camera. In a specific embodiment, the outer housing 4 is a plastic outer housing to prevent the outer housing from shielding the signal of the antenna 12 and ensure the signal strength of the antenna device 1.

[0083] In other embodiments, the above camera device 20 may be a functional device 20 of a wireless electronic device. The corresponding functional device can be selected according to the specific function of the electronic device. By detachably connecting the antenna device 1 to the functional device 2, the wireless communication function of the wireless electronic device can be realized.

[0084] Figure 4 FIG. 4 is a schematic cross-sectional structure diagram of an antenna device in an embodiment of the present application. As shown in the figure, the antenna device 1 further includes a driving component 110 disposed in the first housing 11. The antenna 12 is fixedly installed at the output end of the driving component 110, and the driving component 110 is used to drive the antenna 12 to rotate. In a specific embodiment, the driving component 110 can drive the antenna 12 to rotate 360°, or the driving component 110 can drive the antenna 12 to rotate a set angle within a certain range. The present application does not make specific limitations. The driving component 110 can drive the antenna 12 to rotate to face the base station, so that the antenna 12 can receive the signal from the transmitting end and realize the communication function of the antenna 12. Specifically, the signal emitted by the transmitting end can be a microwave signal, and the wireless camera is a microwave camera. The microwave signal can achieve long-distance signal transmission and is suitable for remote communication of wireless cameras. In the prior art, the wireless camera is installed and docked by manually installing and adjusting the direction of the antenna 12. That is, it is necessary to manually adjust the mounting bracket of the wireless camera to adjust the orientation of the antenna 12 so that the antenna 12 is aligned with the transmitting end to realize the communication between the wireless camera and the backend server. The installation and debugging in the prior art are difficult and time-consuming and laborious. In this solution, after the wireless camera is installed, the driving component 110 can be used to drive the antenna 12 to rotate so that the antenna 12 is aligned with the base station to realize the communication function of the wireless camera. This solution reduces the installation and debugging difficulty of the wireless camera and saves labor costs.

[0085] When specifically installing the antenna device 1, the driving component 110 can be installed on the first housing 11 by screws, and the antenna 12 can also be installed on the output end of the driving component 110 by screws. Of course, in other embodiments, the connection manner between the driving component 110 and the first housing 11, and the connection manner between the antenna 12 and the driving component 110 are not limited. For example, a snap connection or other connection manners can also be adopted.

[0086] To make the antenna 12 face the base station, the antenna device 1 further includes a transceiver 130 and a controller 120. The transceiver 130 is connected to the antenna 12 and is used to transmit and receive signals through the antenna 12. The controller 120 is electrically connected to the driving component 110 and can drive the antenna 12 to rotate or drive the antenna 12 to stop rotating by controlling the driving component 110 according to the strength of the signal received by the transceiver 130, so that the antenna 12 of the antenna device 1 faces the base station direction and the strength of the signal received by the transceiver 130 is within a set range. In this solution, after the wireless camera is installed, the controller 120 can drive the antenna 12 to rotate by controlling the driving component 110, adjust the orientation of the antenna 12, and make the strength of the signal received by the transceiver 130 through the antenna 12 meet the requirements, improving the automation degree of the wireless camera to adjust the antenna orientation.

[0087] When specifically setting the controller 120 and the transceiver 130, the controller 120 and the transceiver 130 can both be arranged on the circuit board, that is, the controller 120 and the transceiver 130 are electrically connected through the circuit board.

[0088] It is also possible to electrically connect the controller 120 and the transceiver 130. The controller 120 monitors the strength of the signal received by the transceiver 130. When the controller 120 monitors that the strength of the signal received by the transceiver 130 reaches the set range, the controller 120 controls the driving component 110 to stop rotating, completing the alignment of the antenna 12 with the base station. In addition, when the controller 120 monitors that the strength of the signal received by the transceiver 130 is outside the set range, the driving component 110 can be controlled again to drive the antenna 12 to adjust the direction so that the strength of the signal received by the transceiver 130 is within the set range. In this solution, the controller 120 can control the driving component 110 to adjust the orientation of the antenna 12 at any time according to the strength of the signal received by the transceiver 130, so that the strength of the signal received by the transceiver 130 is within the set range, ensuring the working reliability of the antenna device 1.

[0089] In a specific embodiment, there is no limitation on the acquisition method of the above set range. It can be set according to the experience of technical personnel; or, according to the performance of the antenna device 1, the range that the signal strength needs to reach under the condition of ensuring reliable antenna operation; or, it can be determined by the controller 120 through calculation. For example, by driving the antenna to rotate at least one week by the driving component 110, the signal strength corresponding to the antenna at each position can be obtained, and a range including the maximum value of the signal strength is used as the set range. Specifically, a certain proportional value of the maximum value of the signal strength can be used as the set range, so that the antenna device 1 can obtain a stronger signal at the installation position and improve the working reliability of the antenna device 1.

[0090] The above wireless electronic device may further include a solar power supply device for powering the wireless electronic device. In this solution, both the power supply and signal transmission of the wireless electronic device can be achieved wirelessly. Therefore, the installation location of the wireless electronic device is not restricted by the line setting and can be designed in any area where the wireless electronic device needs to be installed according to requirements. Especially when the wireless electronic device is a wireless monitoring camera device, it can be installed in any area where it is not convenient to lay lines. On the one hand, the cost caused by laying lines can be reduced. On the other hand, wireless monitoring camera devices can be set up in remote or wide areas, with a relatively reliable power supply device and good communication effects.

[0091] After the antenna 12 is aligned with the base station, the above controller 120 can also control the drive assembly 110 to stop rotating and cut off the power supply to the drive assembly 110 to reduce the energy consumption of the wireless camera and improve the working reliability of the camera. Since the wireless camera usually uses solar power supply, reducing the energy consumption of the wireless camera can reduce the power-off situation of the wireless camera caused by less power supply and large energy consumption. Therefore, the working reliability of the wireless camera can be improved. In addition, in order to prevent the wireless camera from easily experiencing power-off due to energy consumption, it is necessary to continuously supply power to the drive assembly 110 by the wireless camera, resulting in large energy consumption, which also poses high requirements on the performance and specifications of the power supply device, and the cost of the power supply device is relatively high, increasing the cost of the wireless camera. Therefore, while reducing the energy consumption, this solution reduces the requirements on the performance and specifications of the power supply device and reduces the cost of the wireless camera.

[0092] The control method of the drive assembly 110 is not specifically limited in this application. For example, in another embodiment, the drive assembly 110 can also be manually controlled to rotate, stop, and / or cut off the power supply. For example, the drive assembly 110 is configured with an operation panel, and the operator observes the strength of the signal received by the receiver 130 and then uses the buttons on the operation panel to control the drive assembly 110 to rotate, stop, and / or cut off the power supply. Or, in another embodiment, the wireless camera can include both the function of automatically controlling the rotation, stop, and / or power-off of the drive assembly by the controller 120 and the function of manually controlling the rotation, stop, and / or power-off of the drive assembly 110. When manually operating to control the drive assembly 110, the system that automatically controls the drive assembly 110 by the controller 120 can be powered off or failed. This solution allows human participation in adjusting the orientation of the antenna 12, which can be set according to the operator's judgment to meet the scenarios and requirements that the controller 120 cannot judge during actual use.

[0093] Please refer to Figure 4The driving assembly 110 includes a motor 1101 and a gear set 1102 drivingly connected to the motor 1101. The gear set 1102 is used to reduce the speed output by the motor 1101 so that the antenna 12 rotates at a lower speed, so as to improve the accuracy of the alignment between the antenna 12 and the transmitting end. Specifically, the motor 1101 can be a brushless DC motor 1101, which can achieve low-speed and high-power operation, output a lower speed, and reduce the requirements for the gear set 1102.

[0094] When the gear set 1102 is specifically set, the transmission ratio of the gear set 1102 can be not less than 50:1. For example, the transmission ratio of the gear can also be 70:1, 80:1, 100:1, 120:1, 130:1, 143:1, 150:1, 152:1, 190:1 or 200:1, etc., which are not listed here one by one. This solution can achieve self-locking of the drive component 110 after the drive component 110 is powered off. That is, after the drive component 110 is powered off, even if the antenna 12 is subject to external interference such as vibration and has a tendency to rotate, it is difficult to overcome the self-locking force of the gear set 1102, so that the antenna 12 is reliably fixed in the set direction, ensuring the reliability of the operation of the antenna 12.

[0095] The driving assembly 110 is mounted on the metal base 111, or, in one embodiment, the driving assembly 110 can also be mounted on the heat sink 17, that is, the driving assembly 110 is fixed by the heat sink 17. There is no need to set up an additional fixing structure for fixing the driving assembly 110, which is conducive to simplifying the structure of the wireless module.

[0096] like Figure 4 As shown, the first shell 11 of the antenna device 1 includes a metal base 111 and a plastic cover 112, and the metal base 111 and the plastic cover 112 are covered to form a cavity. The circuit board 13 of the antenna device 1 is installed on the metal base 111, so that the metal base 111 can dissipate heat for the heating device 141 on the circuit board 13. Since the metal base 111 has shielding properties and the plastic cover 112 does not have shielding properties, the signal quality of the antenna can be guaranteed. Therefore, the antenna 12 arranged in the first shell 11 avoids the metal base 111 along the first direction X, that is, in the first direction X, the antenna 12 is located in the cavity corresponding to the plastic cover 112. The above-mentioned first direction X refers to the direction from the metal base 111 to the plastic cover 112, that is, Figure 3 This solution can prevent the antenna 12 from being shielded by the metal base 111, so that the signal can be reliably transmitted to the antenna 12, ensuring the communication effect of the antenna 12. Figure 5Another cross-sectional structural schematic diagram of the antenna device 1 in the embodiment of the present application. As shown in the figure, in order to reduce the shielding effect of the metal base 111, the antenna 12 can also be inclined at a certain angle, such as 5° to 10°, relative to the first direction X, so that the antenna 12 can more easily receive signals and weaken the influence of the shielding property of the metal base 111.

[0097] Please continue to refer to Figure 4 , the antenna device 1 further includes a circuit board 13 electrically connected to the antenna 12. The electronic devices 14 provided on the circuit board 13 include a heating device 141. Specifically, the heating device 141 can be a high-power electronic device 14 in the electronic devices 14, such as a driving chip, and the heating device 141 generates a large amount of heat. In order to improve the communication ability and service life of the antenna device 1, it is necessary to make the heating device 141 of the circuit board 13 have a good heat dissipation effect. In order to dissipate the heat of the heating device 141 of the circuit board 13, the circuit board 13 can be thermally connected to the metal base 111 at least in the area where the heating device 141 is located, that is, the heat of the heating device 141 of the circuit board 13 can be conducted to the metal base 111. Since the metal base 111 has a high thermal conductivity, the heat can be conducted to the outside relatively quickly. The metal base 111 is equivalent to a radiator for the circuit board 13, thereby improving the communication effect and service life of the antenna device 1.

[0098] Please continue to refer to Figure 4 , in order to facilitate the thermal connection between the metal base 111 and the area of the circuit board 13 where the heating device 141 is located, the metal base 111 can be provided with a boss 1111 facing the circuit board 13, and the boss 1111 is thermally connected to the area of the circuit board 13 where the heating device 141 is located. This solution can improve the reliability of the thermal connection between the metal base 111 and the circuit board 13 and improve the heat dissipation effect of the circuit board 13.

[0099] In a specific embodiment, the metal base 111 is thermally connected to the area of the circuit board 13 where the heating device 141 is located. The metal base 111 can be directly in contact with the area of the circuit board 13 where the heating device 141 is located, or a first thermal conductive layer 16 can be provided between the metal base 111 and the circuit board 13 to conduct heat between the circuit board 13 and the metal base 111. The specific structure of the first thermal conductive layer 16 is not limited, as long as it has good thermal conductivity.

[0100] In an alternative embodiment, the first heat-conducting layer 16 may be a heat-conducting adhesive or a heat-conducting foam. In addition to having good heat conductivity, the heat-conducting adhesive and the heat-conducting foam can also play an adhesive role, improving the stability of the position of the first heat-conducting layer 16 between the circuit board 13 and the metal base 111, and also improving the stability of the installation of the circuit board 13. In addition, the heat-conducting adhesive and the heat-conducting foam also have a certain elasticity, which can play a shock-absorbing role, protect the circuit board 13, and improve the reliability of the operation of the circuit board 13.

[0101] Please continue to refer to Figure 4 , to improve the heat dissipation effect of the circuit board 13, the antenna device 1 further includes a heat dissipation plate 17, which is disposed on the side of the circuit board 13 facing away from the metal base 111, that is, the side of the circuit board 13 facing the antenna 12. At least the area of the circuit board 13 where the heat-generating device 141 is located is thermally connected to the heat dissipation plate 17, so that the heat dissipation plate 17 can also dissipate heat from the heat-generating device 141 of the circuit board 13. The metal base 111 and the heat dissipation plate 17 can be used to dissipate heat from the heat-generating device 141 simultaneously on both sides of the circuit board 13, and the heat dissipation effect is better. The heat dissipation plate 17 may be a metal plate or a heat dissipation plate 17 made of a heat-conducting material such as graphite. Specifically, when the heat dissipation plate 17 is a metal plate, it can be prepared as a sheet metal part to simplify the manufacturing process.

[0102] In a specific embodiment, when the heat dissipation plate 17 is thermally connected to the circuit board 13, the heat dissipation plate 17 may be directly in contact with the area of the circuit board 13 where the heat-generating device 141 is located, or a second heat-conducting layer 18 may be provided between the heat dissipation plate 17 and the circuit board 13 to conduct heat between the circuit board 13 and the heat dissipation plate 17. The specific structure of the second heat-conducting layer 18 is not limited, as long as it has good heat conductivity. In an alternative embodiment, the second heat-conducting layer 18 may be a heat-conducting adhesive or a heat-conducting foam. In addition to having good heat conductivity, the heat-conducting adhesive and the heat-conducting foam can also play an adhesive role, improving the stability of the position of the second heat-conducting layer 18 between the circuit board 13 and the heat dissipation plate 17, and also improving the stability of the installation of the circuit board 13. In addition, the heat-conducting adhesive and the heat-conducting foam also have a certain elasticity, which can play a shock-absorbing role, protect the circuit board 13, and improve the reliability of the operation of the circuit board 13.

[0103] Please continue to refer to Figure 4, the above heat dissipation plate 17 can also be thermally connected to the metal base 111. Specifically, the heat dissipation plate 17 can be extended and lapped on the surface of the metal base 111. The heat dissipation plate 17 can be in contact installation with the metal base 111. Alternatively, a third heat conduction layer 19 can be provided between the heat dissipation plate 17 and the metal base 111 to conduct heat between the heat dissipation plate 17 and the metal base 111 by means of the third heat conduction layer 19. In this solution, the heat generated by the circuit board 13 in the direction away from the metal base 111 can also be conducted to the metal base 111, so that the metal base 111 dissipates the heat to the outside, improving the heat dissipation effect of the circuit board 13. In addition, this solution can also fix the heat dissipation plate 17 to the metal base 111, improving the installation stability of the heat dissipation plate 17. The material of the above third heat conduction layer 19 is not limited either. For example, it can be thermal conductive glue or thermal conductive foam, which will not be elaborated here.

[0104] Please continue to refer to Figure 5 , the antenna device 1 further includes a wire blocking plate 140, which is disposed on the side of the circuit board 13 facing the antenna 12. Among the wires connected to the circuit board 13, the wires that do not need to be connected to the antenna 12 are limited to the side of the wire blocking plate 140 away from the antenna 12. Specifically, the wires that do not need to be connected to the antenna 12 include the wires connecting the circuit board 13 and the imaging device 20, or the wires that need to be provided between the components inside the circuit board 13. This solution can prevent the wires from moving to the area where the antenna 12 is located and hindering the rotation of the antenna 12, so as to ensure that the antenna 12 can rotate normally under the drive of the drive assembly 110 to dock with the transmitting end.

[0105] In another embodiment, the wire blocking plate 140 and the heat dissipation plate 17 can also be an integral structure to simplify the structure of the wireless module. With a single plate-like structural member, both the heat dissipation function and the wire blocking function can be realized.

[0106] Among the wires of the above antenna device 1, there is a first wire 150 connected to the first connector 15. Since the first connector 15 needs to be connected to the imaging device 20, the first wire 150 connected to the first connector 15 needs to be led out from the first housing 11. The first housing 11 has a first through hole 113. The above first wire 150 extends out of the first housing 11 from the first through hole 113 of the first housing 11. There is a waterproof member 160 between the first wire 150 and the first through hole 113 to achieve the waterproof effect of the wireless module. In a specific embodiment, the above waterproof member 160 can be a rubber member. By tightly installing between the first through hole 113, the waterproof member 160 and the first wire 150, the waterproof performance of the antenna device 1 is ensured.

[0107] In addition, the imaging device 20 also has wires, including a second wire connected to the second connector. Since the second connector needs to be connected to the antenna device, the second wire connected to the second connector needs to be led out of the second housing. The second housing has a second through hole, and the second wire extends out of the second housing through the second through hole of the second housing. A seal is provided between the second wire and the second through hole to achieve the sealing of the imaging device 20. In a specific embodiment, the seal may be a sealant. After the second wire extends out of the second through hole, the sealant is disposed between the second wire and the second through hole to make the second housing a sealed structure and ensure the sealing of the imaging device 20.

[0108] The in-vehicle wireless electronic device in the embodiment of the present application also has the antenna device in the above embodiment. The in-vehicle wireless electronic device is disposed in a mobile device, and the mobile device refers to various devices that can operate, such as vehicles or aircraft such as drones. Specifically, it can be various land vehicles in operation such as cars, trucks, trains, or high-speed rails, or various water vehicles such as various types of ships, or air vehicles such as helicopters, or other aircraft or robots, etc. The present application does not make specific limitations. Since the mobile device will inevitably change its running direction during operation, the orientation of the mobile device will also change, and the antenna of the in-vehicle wireless electronic device disposed in the mobile device will also change its orientation. When the antenna of the in-vehicle wireless electronic device faces away from the base station, it may cause the signal received by the transceiver to be weak, resulting in poor communication effect of the in-vehicle wireless electronic device. By using the antenna device in the embodiment of the present application, the controller can control the driving component to adjust the orientation of the antenna at any time according to the strength of the signal received by the transceiver, so that the strength of the signal received by the transceiver is within the set range, and the in-vehicle wireless electronic device maintains a good communication effect. In a specific embodiment, the in-vehicle wireless electronic device may also be the wireless camera in the above embodiment, that is, the in-vehicle wireless camera.

[0109] The present application also provides an antenna adjustment method for a wireless electronic device. Figure 6 As shown in the flowchart of the antenna adjustment method for a wireless electronic device provided by the present application, as shown in the figure, the method includes:

[0110] Step S101, obtaining the strength of the wireless signal;

[0111] Step S102, when the strength of the wireless signal is less than a preset threshold, driving the antenna to rotate to obtain a signal that meets the preset threshold strength; when the strength of the wireless signal is greater than the preset threshold, stopping driving the antenna to rotate, and transmitting the image signal obtained by the imaging device through the antenna.

[0112] When implementing the above method specifically, the antenna can be driven to rotate manually, and the driving of the antenna to rotate can be stopped. For example, the driving of the antenna to rotate or stop rotating can be controlled manually using an operation panel or an operation disk. Alternatively, the controller can also be used to automatically drive or stop driving the antenna to rotate according to the detected strength of the wireless signal. This solution can automatically adjust the orientation of the antenna and improve the automation level of adjusting the antenna orientation of the wireless electronic device. In addition, at any time, when the strength of the wireless signal is less than a preset threshold, the antenna can be driven to rotate so that the strength of the wireless signal is greater than the preset threshold, ensuring the quality of wireless communication of the wireless electronic device.

[0113] For the determination of the above preset threshold, it can be set according to the experience of technicians; or, it can also be the strength that the signal needs to reach under the condition of ensuring the reliable operation of the antenna according to the performance of the wireless electronic device; or, it can be determined by detection and statistics. For example, by driving the antenna to rotate at least one week, the strength of the signal corresponding to each position of the antenna can be obtained, and a certain proportion value of the maximum value of the signal strength can be used as the preset threshold, so that the wireless electronic device can obtain a stronger signal at the installation position and improve the reliability of the operation of the wireless electronic device.

[0114] This method can be used to electrically adjust the antenna of the wireless electronic device, so that the strength of the signal received by the antenna of the wireless electronic device is greater than the preset threshold strength, ensuring the wireless communication effect of the wireless electronic device and improving the speed and quality of the image signal transmitted by the imaging device. This solution replaces the method of manually adjusting the antenna orientation by adjusting the mounting bracket in the prior art, reducing the difficulty of installation and debugging of the wireless electronic device and saving labor costs.

[0115] Figure 7 The flowchart of another method for adjusting the antenna of the wireless electronic device provided by this application is shown in the figure. After the above step S102, it may further include step S103. After stopping driving the antenna to rotate, control the driving component to power off. This can reduce the energy consumption of the wireless electronic device, improve the service life of the wireless electronic device, and extend the maintenance cycle of the wireless electronic device.

[0116] There is no specific limitation on the type of signal that the above antenna can receive. For example, the antenna can receive and transmit wireless signals through microwaves, and the received and transmitted wireless signals are microwave signals. The transmission distance of microwave signals is relatively far. Therefore, when the wireless electronic device is a wireless imaging device, it can be installed in areas with sparse population, such as deserts, river channels or fields. In this scenario, adopting this solution can more conveniently adjust the orientation of the antenna, improve the wireless communication ability of the wireless electronic device, and improve the transmission speed and quality of the images transmitted and acquired by the wireless imaging device.

[0117] The above-mentioned imaging device can specifically be a monitoring imaging device. That is, the monitoring imaging device uses the above method to ensure that the monitoring video can be transmitted more reliably. In addition, this solution is suitable for installation in areas with sparse population, so as to adjust the orientation of the antenna more conveniently and ensure that the signal strength of the monitoring imaging device for transmission and reception can meet the usage requirements.

[0118] Specifically, the above-mentioned imaging device can be a solar-powered imaging device. In this solution, both the power supply and signal transmission of the imaging device can be achieved wirelessly. Therefore, the installation location of the wireless electronic device is not restricted by the wiring arrangement and can be designed in any area where a wireless electronic device needs to be installed according to requirements. Especially when the wireless electronic device is a wireless monitoring imaging device, it can be installed in any area where it is not convenient to lay wires. On the one hand, it can reduce the cost caused by laying wires. On the other hand, wireless monitoring imaging devices can also be set up in remote or wide areas, and they can have a relatively reliable power supply device and good communication effects.

[0119] The above-mentioned wireless electronic device can also be a vehicle-mounted wireless electronic device, which is set in a vehicle. Here, the "vehicle" generally refers to a movable device. When the vehicle-mounted wireless electronic device changes its direction along with the vehicle it depends on, the antenna is driven to rotate to obtain a signal with a strength greater than a preset threshold. The above-mentioned movable device refers to various devices that can operate, such as vehicles or aircraft such as drones. Specifically, it can be various running land vehicles such as cars, buses, trucks, trains or high-speed rails, or various types of water vehicles such as ships, or aerial vehicles such as helicopters, or other aircraft or robots, etc. This application does not make specific restrictions. Since the movable device will inevitably change its running direction during operation, the orientation of the movable device will also change, and the antenna of the vehicle-mounted wireless electronic device set in the movable device will also change its orientation. When the antenna of the vehicle-mounted wireless electronic device faces away from the base station, it may cause the transceiver to receive a weak signal, resulting in a poor communication effect of the vehicle-mounted wireless electronic device. By using the antenna adjustment method in the embodiments of this application, the antenna can be driven to rotate at any time according to the strength of the acquired wireless signal to adjust the orientation of the antenna, so that the strength of the signal received by the antenna is greater than the preset threshold, and the vehicle-mounted wireless electronic device can maintain a good communication effect. In a specific embodiment, the vehicle-mounted wireless electronic device can also be the wireless camera in the above-mentioned embodiment, that is, the vehicle-mounted wireless camera.

[0120] This application also provides an antenna adjustment device for a wireless electronic device. Figure 8 As shown in the figure, which is a schematic structural diagram of an antenna adjustment device for a wireless electronic device provided by this application, the antenna adjustment device includes each unit that implements the antenna adjustment method in the second aspect above. Specifically, it includes an acquisition unit 100 and a control unit 200, where:

[0121] The acquisition unit 100 is configured to acquire the intensity of a wireless signal; the control unit 200 is configured to drive the antenna to rotate to acquire a signal with an intensity satisfying a preset threshold when the intensity of the wireless signal is less than the preset threshold; and when the intensity of the wireless signal is greater than the preset threshold, stop driving the antenna to rotate, and transmit the image signal acquired by the imaging device through the antenna.

[0122] By using this device, the method for antenna adjustment in the second aspect can be implemented, so that the antenna of the wireless electronic device can be electrically adjusted, and the intensity of the signal received by the transceiver is within a set range, so as to ensure the wireless communication effect of the wireless electronic device. This solution replaces the method of manually adjusting the antenna orientation by adjusting the mounting bracket in the prior art, reduces the difficulty of installation and debugging of the wireless electronic device, and saves labor costs.

[0123] The above is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present application, and all of them should be covered by the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
