Description

[0001] This application is a divisional application of the original application with the application number 202010837211.6 and the original filing date of August 19, 2020, and the entire contents of the original application are incorporated herein by reference. TECHNICAL FIELD

[0002] The present application relates to the field of information technology, and in particular to a wireless electronic device, an antenna adjusting method and device. BACKGROUND

[0003] With the continuous improvement of technology, the use of cameras is also more and more, and the environment where the camera needs to be installed is also more and more complex. In particular, for the vast and sparsely populated areas such as deserts, rivers or fields, it may also be necessary to set up cameras, at which time the camera needs to be able to realize wireless communication, and a wireless camera is usually selected for installation. The wireless camera uses solar power to supply power and uses a wireless communication method to realize communication, thereby facilitating the setting of the camera in a vast and sparsely populated area.

[0004] In the process of installation and use of the wireless camera, the microwave antenna of the wireless camera needs to be directed to the set direction to realize communication with the uplink wireless access point. In the prior art, the wireless camera adopts a manual installation and direction adjustment method, which needs to manually align the microwave antenna of the wireless camera with the wireless access point to realize communication between the wireless camera and the back-end server. The installation and debugging are difficult and time-consuming and labor-intensive. SUMMARY

[0005] The present application provides a wireless electronic device, an antenna adjusting method and device, so that the antenna adjusts the direction under the control of the controller, ensures the signal strength of the wireless electronic device, and improves the speed and quality of wireless communication of the wireless electronic device.

[0006] In a first aspect, the present application provides a wireless electronic device, which comprises an antenna device and a functional device connected with the antenna device, wherein the antenna device is used to realize wireless communication, and the functional device is connected with the antenna device in communication, so that the functional device has the function of wireless communication. The antenna device specifically comprises a first shell, and an antenna, a transceiver, a driving assembly and a controller arranged in the first shell. The transceiver is used to transmit and receive signals through the antenna, the driving assembly is used to drive the antenna to rotate, and the controller is used to control the driving assembly to drive the antenna to rotate according to the strength of the signal received by the transceiver, so that the strength of the signal received by the transceiver is located in a set range. Specifically, during the driving of the driving assembly to drive the antenna to rotate, the strength of the signal received by the transceiver is different due to the orientation of the antenna towards the base station or the orientation of the antenna away from the base station. Therefore, the controller controls the driving assembly to drive the antenna to rotate, when the antenna is oriented towards the base station, the strength of the signal received by the transceiver is larger, and the strength of the signal is located in the set range, so that the antenna device can have better communication effect, and the controller controls the driving assembly to stop driving the antenna to rotate, so as to keep the current orientation of the antenna. The wireless electronic device in the present application can adjust the orientation of the antenna under the control of the controller, ensure the strength of the signal received and transmitted by the wireless electronic device, and improve the wireless communication speed and quality of the wireless electronic device. The scheme replaces the method of manually adjusting the installation support to adjust the orientation of the antenna in the prior art, reduces the installation and debugging difficulty of the wireless electronic device, and saves labor cost.

[0007] In a specific technical solution, the controller can be electrically connected with the transceiver, the controller monitors the strength of the signal received by the transceiver, the controller compares the monitored strength of the signal received by the transceiver with the set range, if the strength of the signal received by the transceiver is located outside the set range, the driving assembly is controlled to drive the antenna to rotate, and when the strength of the signal received by the transceiver is located within the set range, the controller controls the driving assembly to stop driving the antenna to rotate, so that the antenna device can reliably transmit and receive signals. The controller can be electrically connected with the driving assembly, so as to control the driving assembly to rotate or stop rotating.

[0008] The specific type of the wireless electronic device is not limited, and a specific 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 use the wireless communication function of the wireless module to realize the transmission of picture signals. The camera device and the antenna device are detachably connected to facilitate the selection of installation or non-installation of the antenna device according to the needs. The camera device includes a second housing and a camera assembly arranged in the second housing. The second housing has a sealed cavity to place the camera assembly in a sealed environment to ensure that the camera assembly can work normally. In this scheme, the camera device and the antenna device are independent individuals, so the sealing requirement of the camera device has no effect on the antenna device, which is beneficial to simplify the assembly and maintenance process of the antenna device. In addition, the camera assembly is in communication connection with the antenna device, so that the image obtained by the camera assembly can be transmitted by the antenna device. The controller can be used to adjust the orientation of the antenna to ensure the reliability of the image transmission of the wireless camera, which is beneficial to improve the speed of image transmission and the quality of transmitted images of the wireless camera.

[0009] The wireless camera can be a microwave camera, that is, the antenna transmits and receives signals through microwaves, which is applied to areas with wide space and few people. For areas with wide space and few people, the distance between the wireless camera and the base station is far, which is not conducive to manually adjusting the support to make the antenna of the antenna device face the base station. When the antenna needs to be adjusted, it is not convenient for the operator to maintain on site. The wireless camera provided by the application can automatically control the orientation of the antenna by using the controller, which reduces the consumption of manpower on the one hand and can timely adjust the orientation of the antenna on the other hand, thereby ensuring the strength of the signal transmitted and received by the antenna device and improving the reliability of the signal transmitted and received by the antenna.

[0010] The detachable connection mode of the antenna device and the camera device is not limited. For example, the antenna device and the camera device can be directly detachably connected, that is, the first housing and the second housing are detachably connected. Alternatively, the detachable connection of the antenna device and the camera device can also be realized through an adapter. Specifically, one end of the adapter is detachably connected with the antenna device, and the other end of the adapter is detachably connected with the camera device. In this way, when the antenna device and the camera device are independent individuals, the structure is relatively simple.

[0011] The wireless electronic device can also be a vehicle-mounted wireless electronic device, which is installed in a vehicle and changes direction with the running of the vehicle, so the orientation of the antenna also changes, which has a certain impact on the signal strength received by the transceiver. In the technical solution of the application, the antenna device in the vehicle-mounted wireless electronic device includes a controller, which can drive the antenna to rotate by controlling the driving assembly 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. The wireless communication capability of the vehicle-mounted wireless electronic device is less affected by the change of the direction of the vehicle, and can be maintained at a good level.

[0012] The wireless electronic device can also include a solar power supply device for supplying power to the wireless electronic device. In this scheme, the power supply and signal transmission of the wireless electronic device can be realized by wireless means, so the installation position of the wireless electronic device can not be limited by the line setting, and the application scenarios of the wireless electronic device can be enriched.

[0013] 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 assembly to be powered off after the driving assembly stops driving the antenna to rotate. When the antenna stops rotating, the driving assembly does not need to work, so it can be in a power-off standby state. When the driving assembly needs to be started, the controller can also control the driving assembly to be powered on, so that the driving assembly can drive the antenna to rotate. This scheme 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 smaller, which is beneficial to reduce the cost of the wireless electronic device.

[0014] When the driving assembly is specifically set, the driving assembly can include a motor and a gear set in transmission connection with the motor. The gear set can reduce the rotation speed output by the motor to make the antenna rotate at a slower speed, which is conducive to determining the orientation of the antenna when the strength of the signal received by the transceiver is large. The transmission ratio of the above-mentioned gear set is not less than 50:1. The larger the transmission ratio is, the more the gear set can form a self-locking structure when the antenna stops rotating, so that the antenna is fixed at the current position and is not easily disturbed by vibration and the like, so as to ensure the quality of the signal received by the transceiver through the antenna.

[0015] In order to realize the purpose of signal transmission and reception of the antenna device, a circuit board needs to be provided, and 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 with the metal base in a heat-conducting manner. The metal base has good heat conductivity, so that the heating device of the circuit board can conduct heat to the outside to improve the heat dissipation effect of the heating device and prolong the service life of the heating device.

[0016] In order to realize the connection between the circuit board and the metal base by heat conduction, a first heat conduction layer can be arranged between the circuit board and the metal base. The first heat conduction layer can be a heat conduction glue or a heat conduction foam, which has heat conduction and elasticity, and is beneficial to improve the contact area between the heat dissipation plate and the metal base and improve the heat dissipation effect.

[0017] The metal base can further include a boss, which is directed to the circuit board and connected to the area of the circuit board provided with the heat generating device by heat conduction. By arranging the boss on the metal base, the reliability of the heat conduction connection between the metal base and the circuit board can be improved.

[0018] In order to improve the heat dissipation effect of the heat generating device of the circuit board, the antenna module can further be provided with a heat dissipation plate, which is arranged on the side of the circuit board away from the metal base and connected to the area of the circuit board provided with the heat generating device by heat conduction. Both sides of the circuit board provided with the heat generating device have heat dissipation structures, so that the heat dissipation effect is good, and a heat generating device with high power can be arranged to improve the performance of the antenna module. A second heat conduction layer can be arranged between the heat dissipation plate and the circuit board, which can also be a heat conduction glue or a heat conduction foam.

[0019] When the heat dissipation plate is arranged, the edge of the heat dissipation plate can be connected to the metal base by heat conduction. The heat dissipation plate can conduct the heat of the heat generating device to the metal base, and the metal base can conduct the heat to the outside to improve the heat dissipation effect of the antenna module. A third heat conduction layer can be arranged between the heat dissipation plate and the metal base, which can also be a heat conduction glue or a heat conduction foam.

[0020] The antenna module can further include a wire blocking plate arranged between the circuit board and the antenna to block the movement of the wire connected to the circuit board to the area where the antenna is located and block the rotation of the antenna.

[0021] In a specific technical solution, the wire blocking plate and the heat dissipation plate can be an integrated structure to simplify the structure of the antenna module.

[0022] In a second aspect, the application provides an antenna adjusting method of a wireless electronic device, which includes:

[0023] Obtaining the strength of the wireless signal;

[0024] When the strength of the wireless signal is less than a preset threshold, driving the antenna to rotate to obtain a signal meeting the preset threshold strength;

[0025] 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 camera through the antenna.

[0026] The method can 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, thereby ensuring the wireless communication effect of the wireless electronic device. The scheme replaces the method of manually adjusting the mounting bracket to adjust the direction of the antenna in the prior art, thereby reducing the difficulty of installation and debugging of the wireless electronic device and saving labor cost. The specific way of obtaining the strength of the wireless signal is not limited, and the strength of the wireless signal can be manually monitored, and the relationship between the strength of the wireless signal and the preset threshold can be manually judged to control the driving of the antenna rotation or the stopping of the driving of the antenna rotation.

[0027] In a specific technical solution, the driving of the antenna rotation and the stopping of the driving of the antenna rotation can be manually operated, for example, an operation panel or an operation disc can be used to control the driving of the antenna rotation or the stopping of the driving of the antenna rotation. Alternatively, a controller can be used to automatically drive or stop driving the antenna rotation according to the monitored strength of the wireless signal. The scheme can automatically adjust the direction of the antenna, thereby improving the automation degree of adjusting the direction of the antenna of the wireless electronic device. In addition, at any time, when the strength of the wireless signal is less than the preset threshold, the antenna can be driven to rotate, so that the strength of the wireless signal is greater than the preset threshold, thereby ensuring the quality of wireless communication of the wireless electronic device.

[0028] In a technical solution, after the driving of the antenna rotation is stopped, the driving assembly can be controlled to be powered off, thereby reducing the energy consumption of the wireless electronic device and improving the service life and reliability of the wireless electronic device.

[0029] The type of the signal received by the antenna is not limited, for example, the antenna can receive and transmit microwave wireless signals, and the transmitted wireless signals are microwave signals.

[0030] The camera device can be a monitoring camera device, in particular a monitoring camera device that transmits wireless signals by using microwaves. The transmission distance of microwave signals is relatively long, so that the wireless electronic device can be installed in a sparsely populated area when the wireless electronic device is a wireless camera device. In this scenario, the direction of the antenna can be conveniently adjusted by using the scheme, thereby improving the wireless communication capability of the wireless electronic device and improving the transmission speed and quality of the images obtained by the wireless camera device.

[0031] In addition, the monitoring camera device can also be a solar-powered camera device, so that the power supply and signal transmission of the camera device can be completely wireless, thereby enriching the application scenarios of the wireless electronic device.

[0032] In addition, the wireless electronic device can also be a vehicle-mounted wireless electronic device, which is arranged in a mobile device. When the vehicle-mounted wireless electronic device changes direction with the vehicle attached thereto, the antenna is driven to rotate to obtain a signal with a strength greater than a preset threshold.

[0033] The antenna adjusting method in the embodiments of the present application can drive the antenna to rotate at any time according to the strength of the acquired wireless signal, so as to adjust the orientation of the antenna, and keep the strength of the signal received by the antenna at a level greater than the preset threshold, so that the vehicle-mounted wireless electronic device can keep good communication effect. In the specific embodiments, the vehicle-mounted wireless electronic device can also be the wireless camera in the above embodiments, i.e., the vehicle-mounted wireless camera.

[0034] In a third aspect, the present application further provides an antenna adjusting device of a wireless electronic device, which comprises units for implementing the method of the second aspect, and specifically comprises an acquisition unit and a control unit, wherein:

[0035] The acquisition unit is configured to acquire the strength of the wireless signal; and the control unit is configured to drive the antenna to rotate to acquire a signal meeting the preset threshold strength when the strength of the wireless signal is less than the preset threshold, and stop driving the antenna to rotate when the strength of the wireless signal is greater than the preset threshold, and transmit the image signal acquired by the camera through the antenna.

[0036] The device can 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, so as to ensure the wireless communication effect of the wireless electronic device. The scheme replaces the method of manually adjusting the orientation of the antenna by adjusting the mounting bracket in the prior art, reduces the difficulty of installation and debugging of the wireless electronic device, and saves labor cost.

[0037] The specific manner in which the acquisition unit acquires the strength of the wireless signal is not limited, and specifically, the strength of the wireless signal can be manually monitored, and the relationship between the strength of the wireless signal and the preset threshold can be manually judged to control the driving of the antenna to rotate or stop driving the antenna to rotate. Alternatively, the strength of the wireless signal can also be automatically monitored to acquire the strength of the wireless signal, and the acquired strength of the wireless signal can be compared with the preset threshold to drive or stop driving the antenna to rotate. The scheme can automatically adjust the orientation of the antenna, and improve the automation degree of adjusting the orientation of the antenna of the wireless electronic device. In addition, at any time, when the strength of the wireless signal is less than the preset threshold, the antenna can be driven to rotate, so that the strength of the wireless signal is greater than the preset threshold, and the quality of the wireless communication of the wireless electronic device is ensured.

[0038] In a fourth aspect, the present application provides a chip which is installed in the wireless electronic device and can implement the method in any of the above technical solutions. For example, the chip can monitor the strength of the wireless signal received by the antenna, and perform corresponding operation, and then generate a driving signal to drive the antenna to rotate or stop driving the antenna to rotate.

[0039] On the basis of the implementation manners of the above aspects provided by the present application, further combinations can be made to provide more implementation manners. BRIEF DESCRIPTION OF DRAWINGS

[0070] In order to make the purposes, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the drawings.

[0071] In order to facilitate the understanding of the wireless electronic device, the antenna adjusting method and the device provided by the embodiments of the present application, the application scenario thereof will be introduced first.

[0072] The wireless electronic device provided by the embodiments of the present application can be any electronic device which needs to realize wireless communication. Figure 1 For a structural schematic diagram of the wireless electronic device in the embodiments of the present application, please refer to Figure 1The wireless electronic device comprises the antenna device 1 and a functional device 2, wherein the antenna device 1 is used to realize wireless communication, and the functional device 2 is in communication connection with the antenna device 1, so that the functional device 2 has the function of wireless communication. The functional device 2 can be a camera device 20, and the wireless electronic device is a wireless camera. The wireless camera can realize wireless communication by using the antenna device 1. The wireless camera can be a microwave camera, and the antenna 12 in the antenna device 1 is used to receive microwave signals. The wireless camera is usually used in a wide and sparsely populated area such as a desert, a river or a field. It is difficult to lay lines in the above area, so the wireless camera is usually arranged to realize long-distance communication and power supply by using solar energy. During use, the camera device 20 needs to cooperate with the antenna 12 to realize wireless communication of the camera device 20, so as to realize wireless transmission of images obtained by the camera device 20.

[0073] In another embodiment, the wireless electronic device can also be a vehicle-mounted wireless electronic device. It should be noted that the vehicle-mounted wireless electronic device herein refers to a wireless electronic device installed on a mobile device, such as a vehicle or an unmanned aerial vehicle or any moving equipment, and does not simply refer to a wireless electronic device installed on a vehicle. Since the mobile device often needs to change direction during movement, the controller 120 of the antenna device 1 in the embodiment can control the antenna 12 to rotate, so that the strength 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 the vehicle can also be a vehicle-mounted camera or any electronic device that needs to communicate, which is not limited in the application.

[0074] Please continue to refer to Figure 1The electronic device in the embodiment of the present application comprises an antenna device 1 and a functional device 2, wherein the antenna device 1 comprises a first housing 11, and an antenna 12, a transceiver 130, a driving assembly 110 and a controller 120 arranged in the first housing 11. The transceiver 130 transceives signals through the antenna 12 to realize the communication function of the antenna device 1. The driving assembly 110 is controlled by the controller 120 to control the rotation of the antenna 12. Specifically, the controller 120 controls the driving assembly 110 to drive the antenna 12 to rotate 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. In the scheme, the wireless electronic device can use the controller 120 to control the driving assembly 110 to drive the antenna 12 to rotate, so that the antenna 12 is aligned with the base station, and the strength of the signal received by the transceiver 130 meets the preset requirement, so as to realize the communication function of the wireless camera. The scheme replaces the method of manually adjusting the installation support to adjust the direction of the antenna in the prior art, reduces the installation and debugging difficulty of the wireless electronic device, and saves labor cost.

[0075] In a specific embodiment, the controller 120 is electrically connected with the transceiver 130 and the driving assembly 110 respectively. The controller 120 monitors the strength of the signal received by the transceiver 130, and controls the driving assembly 110 according to the monitored strength of the signal received by the transceiver 130, so that the driving assembly 110 drives the antenna 12 to rotate, and the driving assembly 110 stops driving the antenna 12 to rotate when the strength of the signal received by the transceiver 130 is within the set range. The scheme can automatically control the driving assembly 110 to act through the controller 120 after the wireless camera is installed, thereby improving the automation degree of the wireless camera. The strength of the signal received by the transceiver 130 is kept within the set range, which can ensure the wireless communication effect of the wireless camera, so as to 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.

[0076] When realizing the detachable connection of the antenna device 1 and the functional device 2, the specific connection mode is not limited, for example, the connection can be threaded, clamped or clamped. When the functional device 2 is connected with the transceiver 130 of the antenna device 1, a connector can be selected for easy installation and disassembly, or a bare wire connection can also be used.

[0077] For the convenience of description, the wireless electronic device in the embodiment of the present application is taken as a wireless camera as an example to illustrate various possible implementation manners of the wireless electronic device in the embodiment of the present application.

[0078] Figure 2This is a structural schematic diagram of a wireless camera in an embodiment of the present application. As shown in the figure, the wireless camera includes an antenna device 1 and a camera device 20. The antenna device 1 includes a first shell 11, and an antenna 12 and a circuit board 13 arranged in the cavity of the first shell 11. The circuit board 13 is provided with an electronic device 14, and the antenna 12 is electrically connected to the circuit board 13. When the antenna 12 and the circuit board 13 are electrically connected, 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 direction. The camera device 20 includes a second shell 21, and a camera assembly 22 arranged in the second shell 21. The second shell 21 has a sealed cavity, and the camera assembly 22 is arranged in the sealed cavity of the second shell 21. The antenna device 1 and the camera device 20 are detachably connected, 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 and the camera device 20 are connected, the first connector 15 and the second connector 23 can be connected to achieve communication between the camera device 20 and the antenna device 1. Specifically, the first connector 15 and the second connector 23 can be connectors that can be plugged together to achieve electrical connection, or they can be connected using bare wires, and this application does not impose specific restrictions.

[0079] Figure 3 It is a structural diagram of a wireless camera in the prior art, such as Figure 3 As shown, in the prior art, a wireless camera includes a housing 01, a camera assembly 02, and an antenna assembly 03. Antenna assembly 03 includes an antenna 031 and a circuit board 032 connected to antenna 031. Circuit board 032 and camera assembly 02 are located within housing 01, while antenna 031 is located outside of housing 01. Because camera assembly 02 must operate in a sealed environment, the interior of housing 01 is sealed, for example, meeting IP66 protection. In this solution, the need for housing 01 to maintain airtightness complicates the manufacturing process and makes maintenance difficult.

[0080] In the technical solution of the present application, the antenna device 1 and the camera device 20 respectively have the first shell 11 and the second shell 21, and are two relatively independent structures. Therefore, the air tightness requirement of the camera device 20 has no influence on the antenna device 1, and in use, the user can reconfigure the antenna device 1 according to the requirement. In addition, the camera device 20 and the antenna device 1 can be used independently. When the antenna device 1 is not needed, the camera 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 basis of the existing camera device 20 to form a wireless camera. Therefore, the function of the camera is enriched, and the appropriate camera can be configured according to the requirement, which is beneficial to reduce the cost. In addition, in the embodiment of the present application, the antenna 12 is installed in the antenna device 1, which can also protect the antenna 12 and improve the service life of the antenna 12.

[0081] Please continue to refer to Figure 2 The wireless camera further includes an adapter 3, and the antenna device 1 and the camera device 20 are respectively installed at two ends of the adapter 3 to realize detachable connection of the antenna device 1 and the camera device 20. That is, the antenna device 1 is detachably connected with one end of the adapter 3, and the camera device 20 is detachably connected with the other end of the adapter 3. In addition, the first joint 15 and the second joint 23 are connected to realize assembly of the camera device 20 and the antenna device 1, thereby forming the wireless camera. In this scheme, by arranging the adapter 3, the connection structure of the antenna device 1 and the camera device 20 is simplified, so that the antenna device 1 and the camera device 20 are relatively simple in structure when they are independent individuals. Of course, in other embodiments, the wireless camera can also not include the adapter 3, and the camera device 20 and the antenna device 1 can be directly detachably connected.

[0082] In the specific implementation of the detachable connection between the antenna device 1 and the adapter, the detachable connection between the camera device 20 and the adapter, or the detachable connection between the antenna device 1 and the camera device 20, the two detachable connection structures can be threadedly connected, screw-connected, clamped or clamped, which is not limited in the present application.

[0083] Please continue to refer to Figure 2 The wireless camera can further include an outer shell 4, which is formed with a receiving cavity. After the camera device 20 and the antenna device 1 are assembled, they can be installed into the receiving cavity of the outer shell 4. The outer shell 4 can protect the structures of the camera device 20, the antenna device 1 and the connection area, thereby improving the reliability of the wireless camera, and further improving the integrity of the wireless camera. In a specific embodiment, the outer shell 4 is a plastic outer shell, so as to prevent the outer shell from shielding the signal of the antenna 12 and ensure the strength of the signal of the antenna device 1.

[0084] In other embodiments, the camera 20 can be a functional device 20 of a wireless electronic device, and the corresponding functional device can be selected according to the specific function of the electronic device. By detachably connecting the antenna device 1 and the functional device 2, the wireless communication function of the wireless electronic device can be realized.

[0085] Figure 4 A sectional view of the antenna device in the embodiments of the present application is shown in the figure. The antenna device 1 further comprises a driving assembly 110 arranged in the first housing 11. The antenna 12 is fixedly installed at the output end of the driving assembly 110, and the driving assembly 110 is used to drive the antenna 12 to rotate. In specific embodiments, the driving assembly 110 can drive the antenna 12 to rotate 360°, or the driving assembly 110 can drive the antenna 12 to rotate a set angle within a certain range, which is not limited in the present application. The driving assembly 110 can drive the antenna 12 to rotate to be opposite to the base station, so that the antenna 12 can receive the signal from the transmitting end, and the communication function of the antenna 12 can be realized. Specifically, the signal emitted by the transmitting end can be a microwave signal, and the wireless camera can be a microwave camera. The microwave signal can realize signal transmission at a long distance, and is suitable for long-distance communication of the wireless camera. In the prior art, the wireless camera is installed and docked by manually installing and adjusting the direction of the antenna 12. That is, the installation rack of the wireless camera needs to be manually adjusted 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 back-end server. The installation and debugging of the prior art are difficult and time-consuming. In this scheme, after the wireless camera is installed, the driving assembly 110 is 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 scheme reduces the installation and debugging difficulty of the wireless camera and saves labor cost.

[0086] When the antenna device 1 is installed, the driving assembly 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 assembly 110 by screws. Of course, in other embodiments, the connection mode between the driving assembly 110 and the first housing 11, and the connection mode between the antenna 12 and the driving assembly 110 are not limited, for example, a clamping connection mode can also be used.

[0087] In order to realize the alignment of the antenna 12 and the base station, the antenna device 1 further comprises a transceiver 130 and a controller 120, the transceiver 130 is connected with the antenna 12 and is used for receiving and transmitting signals through the antenna 12, the controller 120 is electrically connected with the driving assembly 110 and can control the driving assembly 110 to drive the antenna 12 to rotate or stop rotating according to the strength of the signal received by the transceiver 130, so that the antenna 12 of the antenna device 1 is directed to the direction of the base station and the strength of the signal received by the transceiver 130 is within the set range. According to the scheme, after the wireless camera is installed, the controller 120 can control the driving assembly 110 to drive the antenna 12 to rotate and adjust the direction of the antenna 12, so that the strength of the signal received by the transceiver 130 through the antenna 12 meets the requirements, and the automation degree of the wireless camera in adjusting the direction of the antenna is improved.

[0088] When the controller 120 and the transceiver 130 are specifically arranged, the controller 120 and the transceiver 130 can be arranged on the circuit board, that is, the controller 120 and the transceiver 130 are electrically connected through the circuit board.

[0089] The controller 120 and the transceiver 130 can also be electrically connected, 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 assembly 110 to stop rotating, and the alignment of the antenna 12 and the base station is completed. In addition, when the controller 120 monitors that the strength of the signal received by the transceiver 130 is out of the set range, the driving assembly 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 the scheme, the controller 120 can control the driving assembly 110 to adjust the direction 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, and the working reliability of the antenna device 1 is ensured.

[0090] In specific embodiments, the way of obtaining the set range is not limited, which can be set according to the experience of technicians, or the range of the strength of the signal that needs to be reached under the condition of ensuring the working reliability of the antenna according to the performance of the antenna device 1, or the controller 120 can determine it by calculation, for example, by driving the antenna to rotate at least one circle, the strength of the signal corresponding to each position of the antenna can be obtained, and a range including the maximum value of the strength of the signal is taken as the set range. Specifically, a certain proportion of the maximum value of the strength of the signal can be taken 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.

[0091] The wireless electronic device can further comprise a solar power supply device for supplying power to the wireless electronic device. In this scheme, both the power supply and signal transmission of the wireless electronic device can be achieved wirelessly, so that the location of the wireless electronic device can not be limited by the line layout, and can be designed in any area where the wireless electronic device is required to be installed. In particular, when the wireless electronic device is a wireless monitoring camera, it can be installed in any area where it is inconvenient to lay lines. On the one hand, it can reduce the cost of laying lines, and on the other hand, it can set up a wireless monitoring camera in a remote or wide area, which can have a more reliable power supply device and have a better communication effect.

[0092] The controller 120 can also control the driving assembly 110 to stop rotating and be powered off after the antenna 12 is aligned with the base station, so as to reduce the power consumption of the wireless camera and improve the working reliability of the camera. Since the wireless camera is usually powered by solar energy, reducing the power consumption of the wireless camera can reduce the power-off situation caused by insufficient power supply and large power consumption of the wireless camera, thereby improving the working reliability of the wireless camera. In addition, in order to prevent the wireless camera from being powered off due to power consumption, the wireless camera needs to continuously supply power to the driving assembly 110, which results in large power consumption and high requirements for the performance and specifications of the power supply device, thereby increasing the cost of the power supply device and the cost of the wireless camera. Therefore, the present scheme reduces the power consumption while reducing the requirements for the performance and specifications of the power supply device and the cost of the wireless camera.

[0093] The control mode of the driving assembly 110 is not specifically limited in the present application. For example, in another embodiment, the driving assembly 110 can also be manually controlled to rotate, stop and / or be powered off. For example, the driving assembly 110 is provided with an operation panel, and an operator observes the strength of the signal received by the receiver 130, and then controls the driving assembly 110 to rotate, stop and / or be powered off by using the buttons of the operation panel. Alternatively, in another embodiment, the wireless camera can have both the function of automatically controlling the driving assembly to rotate, stop and / or be powered off by the controller 120 and the function of manually controlling the driving assembly 110 to rotate, stop and / or be powered off. When the driving assembly 110 is manually operated, the system of automatically controlling the driving assembly 110 by the controller 120 can be powered off or disabled. This scheme can manually participate in the adjustment of the orientation of the antenna 12, and can be set according to the judgment of the operator to meet the scenes and requirements that cannot be judged by the controller 120 in actual use.

[0094] Please refer to Figure 4The driving assembly 110 comprises a motor 1101 and a gear set 1102 in transmission connection with the motor 1101, which is used to reduce the rotating speed output by the motor 1101, so as to rotate the antenna 12 at a lower speed, thereby improving the accuracy of the alignment of the antenna 12 with the transmitting end. Specifically, the motor 1101 can be a brushless direct current motor 1101, which can be operated at a low speed and high power to output a smaller rotating speed, thereby reducing the requirement on the gear set 1102.

[0095] When the gear set 1102 is specifically arranged, 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, and the like, which are not listed one by one. This scheme can realize self-locking of the driving assembly 110 after the driving assembly 110 is powered off. That is, after the driving assembly 110 is powered off, even if the antenna 12 is disturbed by external interference such as vibration and tends to rotate, it is difficult to overcome the self-locking force of the gear set 1102, so that the antenna 12 can be reliably fixed in the set orientation, thereby ensuring the reliability of the antenna 12.

[0096] The driving assembly 110 is installed on the metal base 111, or in an embodiment, the driving assembly 110 can also be installed on the heat dissipation plate 17, that is, the driving assembly 110 is fixed by using the heat dissipation plate 17. Therefore, it is not necessary to additionally arrange a fixing structure for fixing the driving assembly 110, which is conducive to simplifying the structure of the wireless module.

[0097] As shown in Figure 4 , the first housing 11 of the antenna device 1 comprises a metal base 111 and a plastic cover 112, and the metal base 111 and the plastic cover 112 are combined 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 property and the plastic cover 112 does not have shielding property, the signal quality of the antenna can be ensured. Therefore, the antenna 12 arranged in the first housing 11 avoids the metal base 111 in 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 first direction X refers to the direction of the metal base 111 towards the plastic cover 112, that is, the vertical direction in Figure 3 . This scheme can avoid the shielding of the antenna 12 by the metal base 111, so that the signal can be reliably transmitted to the antenna 12, thereby ensuring the communication effect of the antenna 12. Figure 5As shown in the figure, in order to reduce the shielding effect of the metal base 111, the antenna 12 can be inclined at an angle, for example, 5°-10°, relative to the first direction X, so that the antenna 12 is more likely to receive signals and the shielding effect of the metal base 111 is weakened.

[0098] Please continue to refer to Figure 4 The antenna device 1 further includes a circuit board 13 electrically connected with the antenna 12. The electronic device 14 provided on the circuit board 13 includes a heat generating device 141. Specifically, the heat generating device 141 can be a high-power electronic device 14 in the electronic device 14, for example, a driving chip. The heat generating device 141 generates a large amount of heat. In order to improve the communication capability and service life of the antenna device 1, the heat generating device 141 of the circuit board 13 needs to have a good heat dissipation effect. In order to dissipate heat of the heat generating device 141 of the circuit board 13, the circuit board 13 can be in heat conduction connection with at least the region of the heat generating device 141, that is, the heat of the heat generating device 141 of the circuit board 13 can be conducted to the metal base 111. Since the metal base 111 has high thermal conductivity, the heat can be quickly conducted to the outside. The metal base 111 is equivalent to a heat sink for the circuit board 13, thereby improving the communication effect and service life of the antenna device 1.

[0099] Please continue to refer to Figure 4 In order to facilitate heat conduction connection between the metal base 111 and the region of the circuit board 13 with the heat generating device 141, the metal base 111 can have a boss 1111 facing the circuit board 13, and the boss 1111 is in heat conduction connection with the region of the circuit board 13 with the heat generating device 141. This scheme can improve the reliability of heat conduction connection between the metal base 111 and the circuit board 13 and improve the heat dissipation effect of the circuit board 13.

[0100] In specific embodiments, the metal base 111 is in heat conduction connection with the region of the circuit board 13 with the heat generating device 141. The metal base 111 can be directly in contact with the region of the circuit board 13 with the heat generating device 141, or a first heat conduction layer 16 can be arranged 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 heat conduction layer 16 is not limited as long as it has good heat conductivity.

[0101] In an optional embodiment, the first heat-conductive layer 16 can be heat-conductive glue or heat-conductive foam. In addition to good heat conductivity, the heat-conductive glue and the heat-conductive foam can also play a role of adhesion, improve the stability of the position of the first heat-conductive layer 16 between the circuit board 13 and the metal base 111, and also improve the stability of the installation of the circuit board 13. In addition, the heat-conductive glue and the heat-conductive foam also have a certain elasticity, can play a role of shock absorption, can protect the circuit board 13, and improve the reliability of the work of the circuit board 13.

[0102] Please continue to refer to Figure 4 In order to improve the heat dissipation effect of the circuit board 13, the antenna device 1 further comprises a heat dissipation plate 17, which is arranged on the side of the circuit board 13 away from the metal base 111, that is, the side of the circuit board 13 facing the antenna 12. At least the region of the circuit board 13 with the heat generating device 141 is in heat-conductive connection with the heat dissipation plate 17, so that the heat dissipation plate 17 can also dissipate heat for the heat generating device 141 of the circuit board 13. The metal base 111 and the heat dissipation plate 17 can be used to simultaneously dissipate heat for the heat generating device 141 on both sides of the circuit board 13, and the heat dissipation effect is good. The heat dissipation plate 17 can be a metal plate, or a heat dissipation plate 17 made of a heat-conductive material such as graphite. Specifically, when the heat dissipation plate 17 is a metal plate, it can be prepared into a sheet metal part to simplify the preparation process.

[0103] In a specific embodiment, when the heat dissipation plate 17 is in heat-conductive connection with the circuit board 13, the heat dissipation plate 17 can be directly in contact with the region of the circuit board 13 with the heat generating device 141, or a second heat-conductive layer 18 can be arranged between the heat dissipation plate 17 and the circuit board 13, and the second heat-conductive layer 18 is used to conduct heat between the circuit board 13 and the heat dissipation plate 17. The specific structure of the second heat-conductive layer 18 is not limited, as long as it has good heat conductivity. In an optional embodiment, the second heat-conductive layer 18 can be heat-conductive glue or heat-conductive foam. In addition to good heat conductivity, the heat-conductive glue and the heat-conductive foam can also play a role of adhesion, improve the stability of the position of the second heat-conductive layer 18 between the circuit board 13 and the heat dissipation plate 17, and also improve the stability of the installation of the circuit board 13. In addition, the heat-conductive glue and the heat-conductive foam also have a certain elasticity, can play a role of shock absorption, can protect the circuit board 13, and improve the reliability of the work of the circuit board 13.

[0104] Please continue to refer to Figure 4The heat dissipation plate 17 can also be in thermal contact with the metal base 111. Specifically, the heat dissipation plate 17 can be extended and lapped onto the surface of the metal base 111. The heat dissipation plate 17 can be in contact with the metal base 111, or a third thermal conductive layer 19 can be arranged 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. In this scheme, the heat dissipation plate 17 can conduct the heat generated by the circuit board 13 away from the metal base 111 to the metal base 111 to dissipate heat to the outside by the metal base 111, thereby improving the heat dissipation effect of the circuit board 13. In addition, this scheme can also fix the heat dissipation plate 17 to the metal base 111, thereby improving the installation stability of the heat dissipation plate 17. The material of the third thermal conductive layer 19 is not limited, for example, it can be thermal conductive glue or thermal conductive foam, which will not be described here.

[0105] Please continue to refer to Figure 5 The antenna device 1 further comprises a wire blocking plate 140 arranged 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 above-mentioned wires that do not need to be connected to the antenna 12 include wires connected between the circuit board 13 and the camera 20, or wires needed to be arranged between devices inside the circuit board 13. This scheme can prevent the wires from moving to the area where the antenna 12 is located, thereby preventing the rotation of the antenna 12, so as to ensure that the antenna 12 can normally rotate under the drive of the drive assembly 110 to be connected with the transmitting end.

[0106] In another embodiment, the wire blocking plate 140 and the heat dissipation plate 17 can be integrated into one structure to simplify the structure of the wireless module, and one plate-shaped structure can realize both heat dissipation and wire blocking functions.

[0107] Among the wires of the above-mentioned antenna device 1, the first wire 150 connected to the first connector 15 needs to be drawn out of the first shell 11 because the first connector 15 needs to be connected to the camera 20. The first shell 11 has a first through hole 113, and the first wire 150 extends out of the first shell 11 from the first through hole 113 of the first shell 11. A waterproof member 160 is arranged between the first wire 150 and the first through hole 113 to realize the waterproof effect of the wireless module. In a specific embodiment, the waterproof member 160 can be a rubber member, which is tightly installed between the first through hole 113, the waterproof member 160 and the first wire 150 to ensure the waterproof performance of the antenna device 1.

[0108] In addition, the camera 20 also has a wire, including a second wire connected to the second joint. Since the second joint needs to be connected to the antenna device, the second wire connected to the second joint needs to be drawn out of the second shell. The second shell has a second through hole, and the second wire is drawn out of the second shell from the second through hole of the second shell. The second wire and the second through hole have a seal therebetween to achieve the sealing of the camera 20. In specific embodiments, the seal can be sealant, and the sealant is arranged between the second wire and the second through hole after the second wire is drawn out of the second through hole, so that the second shell is in a sealed structure and the sealing of the camera 20 is ensured.

[0109] The vehicle-mounted wireless electronic device in the embodiments of the present application also has the antenna device in the above-mentioned embodiments. The vehicle-mounted wireless electronic device is arranged in a mobile device, which refers to various devices that can run, such as vehicles or unmanned aerial vehicles and the like, and can be various running land vehicles such as cars, automobiles, trucks, trains or high-speed rails, or various types of ships such as water vehicles, or helicopters and the like air vehicles, or other aircraft or robots, which are not specifically limited in the present application. Since the mobile device will inevitably change the running direction during running, the orientation of the mobile device will also change, and the orientation of the antenna of the vehicle-mounted wireless electronic device arranged in the mobile device will also change. When the antenna of the vehicle-mounted wireless electronic device is oriented away from the base station, the signal received by the transceiver can be weak, resulting in poor communication effect of the vehicle-mounted wireless electronic device. By using the antenna device in the embodiments of the present application, the controller can control the driving assembly 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 vehicle-mounted wireless electronic device maintains good communication effect. In specific embodiments, the vehicle-mounted wireless electronic device can also be a wireless camera in the above-mentioned embodiments, i.e. a vehicle-mounted wireless camera.

[0110] The present application also provides an antenna adjusting method of a wireless electronic device, Figure 6 A flowchart of an antenna adjusting method of a wireless electronic device provided by the present application is shown in the figure. The method comprises:

[0111] Step S101, obtaining the strength of the wireless signal;

[0112] Step S102, when the strength of the wireless signal is less than the preset threshold, driving the antenna to rotate to obtain a signal meeting 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 camera through the antenna.

[0113] In the implementation of the method, the antenna can be manually driven to rotate and stop rotating, for example, the antenna can be manually controlled to rotate or stop rotating by using an operation panel or an operation disc. Alternatively, the antenna can be automatically driven to rotate or stop rotating by using a controller according to the monitored strength of the wireless signal. This scheme can automatically adjust the orientation of the antenna, and improve the automation of the wireless electronic device in adjusting the orientation of the antenna. In addition, at any time, when the strength of the wireless signal is less than the preset threshold, the antenna can be driven to rotate, so that the strength of the wireless signal is greater than the preset threshold, to ensure the quality of wireless communication of the wireless electronic device.

[0114] For the determination of the above-mentioned preset threshold, the preset threshold can be set according to the experience of the technician, or the strength of the signal required to be reached under the condition of ensuring the reliable operation of the antenna according to the performance of the wireless electronic device, or the preset threshold 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 of the maximum value of the strength of the signal is taken as the preset threshold, so that the wireless electronic device can obtain a stronger signal at the installation position, and the reliability of the operation of the wireless electronic device is improved.

[0115] By using the method, the antenna of the wireless electronic device can be electrically adjusted, so that the strength of the signal received by the antenna of the wireless electronic device is greater than the preset threshold, to ensure the wireless communication effect of the wireless electronic device, and the speed and quality of the transmission of the image signal of the camera device are improved. This scheme replaces the method of manually adjusting the orientation of the antenna by adjusting the mounting bracket in the prior art, reduces the difficulty of installation and debugging of the wireless electronic device, and saves labor cost.

[0116] Figure 7 Another flowchart of an antenna adjustment method of a wireless electronic device is provided in the present application, as shown in the figure, after the above-mentioned step S102, the method can further include the step S103 of controlling the driving assembly to be powered off after the driving of the antenna is stopped. This can reduce the energy consumption of the wireless electronic device, improve the service life of the wireless electronic device, and prolong the maintenance period of the wireless electronic device.

[0117] The type of the signal received by the antenna is not specifically limited, for example, the antenna can receive and transmit microwave signals. The transmission distance of the microwave signal is relatively far, so that the wireless electronic device can be installed in a sparsely populated area, such as a desert, a river or a field. In this scenario, the orientation of the antenna can be conveniently adjusted by using the present scheme, the wireless communication capability of the wireless electronic device is improved, and the transmission speed and quality of the image obtained by the wireless camera device are improved.

[0118] The camera device can be a monitoring camera device. The monitoring camera device can ensure reliable transmission of a monitoring image by using the method. In addition, the scheme is suitable for installation in a sparsely populated area, and the orientation of the antenna can be conveniently adjusted to ensure that the strength of the signal received and transmitted by the monitoring camera device meets the use requirements.

[0119] In particular, the camera device can be a solar-powered camera device. In this scheme, the power supply and signal transmission of the camera device can be achieved by using a wireless method. Therefore, the installation position of the wireless electronic device is not limited by the line layout, and the wireless electronic device can be designed in any area where it is required to be installed. In particular, when the wireless electronic device is a wireless monitoring camera device, it can be installed in any area where it is inconvenient to lay lines. On the one hand, the cost of laying lines can be reduced. On the other hand, the wireless monitoring camera device can be installed in remote or wide areas, and can have a reliable power supply device and good communication effect.

[0120] The wireless electronic device can also be a vehicle-mounted wireless electronic device. The vehicle-mounted wireless electronic device is arranged in a vehicle. Here, the vehicle refers to a movable device. When the vehicle-mounted wireless electronic device changes direction with the vehicle attached thereto, the antenna is driven to rotate to obtain a signal with a strength greater than a preset threshold. The movable device refers to various devices that can run, such as vehicles or unmanned aerial vehicles, and the like. Specifically, the movable device can be a variety of running land vehicles, such as a sedan, a car, a truck, a train, or a high-speed rail, or a variety of water vehicles, such as a ship, or an air vehicle, such as a helicopter, or other aerial vehicles or robots, and the like. The application does not make specific limitations. Since the movable device changes the running direction during operation, the orientation of the movable device also changes, and the orientation of the antenna of the vehicle-mounted wireless electronic device arranged in the movable device also changes. When the antenna of the vehicle-mounted wireless electronic device faces away from the base station, the signal received by the transceiver can be weak, which can result in poor communication effect of the vehicle-mounted wireless electronic device. By using the antenna adjustment method in the application, the antenna can be driven to rotate at any time according to the strength of the wireless signal obtained, so as 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 maintains good communication effect. In specific embodiments, the vehicle-mounted wireless electronic device can also be a wireless camera as described in the above embodiments, i.e., a vehicle-mounted wireless camera.

[0121] The application also provides an antenna adjustment device of a wireless electronic device, Figure 8 A structure diagram of an antenna adjustment device of a wireless electronic device provided by the application is shown in the figure. The antenna adjustment device includes units for implementing the method of adjusting the antenna in the second aspect, specifically including an acquisition unit 100 and a control unit 200.

[0122] The acquisition unit 100 is configured to acquire the strength of the wireless signal; the control unit 200 is configured to drive the antenna to rotate to acquire a signal satisfying the preset threshold strength when the strength of the wireless signal is less than the preset threshold; and stop driving the antenna to rotate when the strength of the wireless signal is greater than the preset threshold, and transmit the image signal acquired by the camera through the antenna.

[0123] The device can realize the method for adjusting the antenna of the second aspect, so that the strength of the signal received by the transceiver is within the set range, thereby ensuring the wireless communication effect of the wireless electronic device. The scheme replaces the method of manually adjusting the installation support to adjust the direction of the antenna in the prior art, reduces the difficulty of installation and debugging of the wireless electronic device, and saves labor cost.

[0124] The above is only a specific implementation 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 replacements within the technical range disclosed in the present application, which should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
