More specifically, the imaging device can be a mobile electronic device that can communicate with an external device. The imaging device may include the housing 1, the mounting part 2, and the antenna device. The mounting part 2 may be disposed protruding from the housing 1. The antenna device may be used to communicate with other external devices, such as mobile phones, computers, and commutation base stations.
The housing 1 may be a housing of an imaging device, and the main devices that can be used to realize its main functions, such as circuit boards, sensors, controllers, and storage devices, can be mounted or housed inside. The housing 1 may be made of metal material, thereby enhancing the structural strength of the imaging device. There are various shapes and sizes of the housing 1, which are not specifically limited here.
The mounting part 2 can be disposed protruding from the housing 1, and there can be various specific implementation methods. For example, a mounting hole may be disposed on the housing 1 matching the shape of the mounting part 2, and he mounting part 2 can be mounted at the mounting hole. In another example, a slot may be disposed on the housing 1, and the mounting part 2 may be locked in the slot. The material of the mounting part 2 may be a non-metal material, such as one or more of plastic, glass, etc.
In some embodiments, the housing 1 may include a top surface 11, a bottom surface 12, and a side surface 13 connected between the top surface 11 and the bottom surface 12, and the mounting part 2 may be disposed on the side surface 13. The top surface 11 may be a surface that faces away from the ground when the imaging device captures an image or a video. The bottom surface may be a surface of the imaging device facing the ground. The side surface 13 may be a surface that is disposed between the top surface 11 and the bottom surface 12 and faces the user when the imaging device is being used. The mounting part 2 may be disposed on the side surface 13. In addition, the mounting part 2 may be disposed on the side surface 13 close to the top surface 11, thereby facilitating the ease of use.
The antenna device may include the antenna 3, which can be used to achieve one or more functions such as obtaining the imaging position of the imaging device, performing image transmission or remote control, etc. The antenna 3 may be a conventional antenna, which is not specifically limited here. The antenna may be disposed in the mounting part 2. Since the mounting part 2 can protrude from the housing 1, there is no need to consider whether there may be interference between the antenna 3 and other components of the imaging device, and the volume of the imaging device can be further reduced.
In addition, since the mounting part 2 may be made of non-metal material, the antenna 3 may be disposed inside it. When the antenna 3 communicates with an external device, the signal sent or received needs to pass through the non-metallic mounting part 2 instead of the metallic housing 1. Therefore, the signal will not be shielded, and the signal transmission effect is better.
The imaging device provided in this embodiment includes a housing, a mounting part, and an antenna device. The housing may be made of metal material, the mounting part may be made of non-metal material, and the mounting part may be disposed protruding from the housing. The antenna device may include antenna, and the antenna may be disposed in the mounting part. When the antenna communicates with an external device, there is no need to consider whether there may be interference between the antenna and other components of the imaging device, and the volume of the imaging device can be further reduced. At the same time, the signal will not be shielded, and the signal transmission effect is better.
Further, as an implementation method of the antenna 3, the antenna 3 may include a first antenna 4 for obtaining geographic location information and a second antenna 5 for implementing remote control and image transmission. As such, the imaging device can realize remote imaging and other operations through the external device, obtain geographic location when the image is captured, transmit the image to the external device, thereby further increasing the operation convenience of the imaging device and the integrity of the image information.
There may be various types of the first antenna 4, which may be a conventional GNSS antenna for obtaining the geographic location information. For example, the first antenna 4 may include one or more of a GNSS antenna, a GPS antenna, a Galileo antenna, or a GLONASS antenna.
Further, the first antenna 4 may be disposed on top of the mounting part 2 facing away from the ground. Since the first antenna 4 can obtain geographic location information, it needs to communicate with satellite in the sky when it works. By disposing the first antenna 4 on the top away from the bottom surface, the first antenna 4 can be closer to the sky when in use, and the signal transmission effect is better.
There may also be various types of the second antenna 5, which may be a conventional antenna that can realize remote control and image transmission. For example, the second antenna 5 may include one or more of a Wi-Fi antenna, a Bluetooth antenna, a WLAN antenna, or a NFC antenna.
As an implementation method of the second antenna 5, the second antenna 5 may include a first antenna part 51 and a second antenna part 52. The first antenna part 51 may be disposed at the top of the mounting part 2 facing away from the ground, and the second antenna part 52 may be disposed at the bottom of the mounting part 2 facing the ground.
More specifically, the second antenna 5 may include two or more antennas. Taking two antennas as an example, one of the antennas may be the first antenna part 51, and the other antenna may be the second antenna part 52. There may also be various types of the first antenna part 51 and the second antenna part 52. For detail, reference may be made to the types of the second antenna 5. In addition, the first antenna part 51 and the second antenna part 52 may be the same type of antenna, or different types of antennas, which are not limited here. In some embodiments, the first antenna part 51 and the second antenna part 52 may be the same type of Wi-Fi antenna, and each Wi-Fi antenna may cover 2.4 G and 5.8 G frequency bands. The first antenna part 51 and the second antenna part 52 may realize dual transmission and dual reception, thereby forming a MIMO antenna and further improving system efficiency. When the first antenna part 51 and the second antenna part 52 send different codes of the same information, the anti-interference ability of the system can be greatly improved while the transmission bandwidth remain unchanged. When the first antenna part 51 and the second antenna part 52 send different codes of different information, the system transmission bandwidth can be greatly improved while the anti-interference ability remain unchanged. In addition, the antenna forms of the first antenna part 51 and the second antenna part 52 may also be IFA, MONOPOLE, LOOP, etc.
The first antenna part 51 may be disposed at the top of the mounting part 2 facing away from the bottom surface, and the second antenna part 52 may be disposed at the bottom of the mounting part 2 facing the ground. As such, the two antennas can be separated from each other, thereby improving the isolation and reducing the mutual influence between the two antennas. It should be understood that the first antenna part 51 may also be disposed at the bottom of the mounting part 2, and the second antenna part 52 may also be disposed at the top of the mounting part 2.

In some embodiments, the first radiator 61 may include a first radiation ground 611, and a first radiation branch 612 and a second radiation branch 613 respectively connected to the first radiation ground 611. The first radiation ground 611 and the first radiation branch 612 together can form the first antenna 4, and the first radiation ground 611 and the second radiation branch 613 together can form the first antenna part 51. As such, the first antenna 4 and the first antenna part 51 can be formed in a radiator in the forming of sharing the first radiation ground 611, thereby reducing the size of the antenna 3 and the mutual interference.
Furthermore, a first FPC unit 6 may be disposed on top of the mounting part 2, and both sides of the first radiator 61 may be respectively covered with a first substrate and a first protective film 63. The first substrate 62, the first protective film 63, and the first radiator 61 together can constitute the first FPC unit 6.
More specifically, in order to prevent the first radiator 61 from being damaged, it may be packaged in the first FPC unit 6. The first FPC unit 6 may be disposed on top of the mounting part 2, which may include the first radiator 61, the first substrate 62, and the first protective film 63. The first protective film 63 and the first substrate 62 may be respectively disposed on both sides of the first radiator 61, thereby sealing the first radiator 61 inside the first FPC unit 6. As such, the first radiator 61 can be prevented from being damaged, which can affect the performance of the first antenna 4 and the first antenna part 51.
As another implementation method of the second antenna part 52, the second antenna part 52 may also be electrically connected to the housing 1. Since the second antenna part 52 can be disposed at the bottom of the mounting part 2, it can be relatively close to other internal components of the imaging device. By electrically connecting the second antenna part 52 with the housing 1, the grounding of the second antenna part 52 can be achieved, which can improve its performance.
It should be understood that, for the first antenna 4 and the first antenna part 51, since they can be both disposed on top of the mounting part 2 and the mounting part 2 can be positioned close to the top surface, the surrounding components may be limited and the performance may be better, and there may be no need for grounding. Of course, in order to further improve performance, the first antenna 4 and the first antenna part 51 may also be grounded.

Furthermore, in order to prevent the second radiator 71 from being damaged, a second FPC unit 7 may be disposed at the bottom of the mounting part 2. Both sides of the second radiator 71 may be respectively covered with a second substrate 72 and a second protective film 73. The second substrate 72, the second protective film 73, and the second radiator 71 together can constitute the second FPC unit 7. More specifically, the second radiator 71 may be packaged in the second FPC unit 7, and the second FPC unit 7 may be disposed at the bottom of the mounting part 2, which may include the second radiator 71, the second substrate 72, and the second protective film 73. The second protective film 73 and the second substrate 72 may be respectively positioned on both sides of the second radiator 71, thereby sealing the second radiator 71 inside the second FPC unit 7. As such, the second radiator 71 can be prevented from being damaged, which can affect the performance of the second antenna part 52.
In addition, the second radiator 71 and the housing 1 may be electrically connected in various ways. For example, a wire may be disposed between the second protective film 73 and the second substrate 72, and the wire may be used for electrical connection. In some embodiments, the second radiator 71 may contact the housing 1 through a conductive member. An opening 74 may be formed on the second protective film 73. The conductive member may pass through the opening 74, such that the conductive member may connect the housing 1 and the second radiator 71 through the opening. The shape and size of the opening 74 may be set based on the actual situation. The connection through the opening 74 can prevent the conductive member from being disposed between the second protective film 73 and the second substrate 72, which can affect the sealing performance of the second FPC unit 7.
In some embodiments, the part of the second radiator 71 corresponding to the opening 74 may be in contact with the housing 1 through conductive member, which can reduce the thickness of the second FPC unit 7 and improve the space utilization of the imaging device.
There may be many types of the conductive member, such as a wire or a conductive block, etc. In some embodiments, the conductive member may include a conductive foam 9. The conductive foam 9 can play the role of connection and buffering at the same time. While achieving electrical connection, it can also prevent the second FPC unit 7 from colliding with the housing 1 when the imaging device is impacted.
In some embodiments, the chip 8 may include a first chip 81 and a second chip 82. The first antenna 4 may be electrically connected to the first chip 81, and the first antenna part 51 and the second antenna part 52 may be electrically connected to the second chip 82, respectively. For example, the first antenna 4 may be a GPS antenna, the first antenna part 51 and the second antenna part 52 may be Wi-Fi antenna, the first chip 81 may be a GPS chip, and the second chip 82 may be a Wi-Fi chip. As such, the control of the GPS antenna and the Wi-Fi antenna can be separated, which is convenient for the function partition management and realization.
Further, the first antenna 4 and the first chip 81 may be electrically connected by a first wire 64. There may be many types of the first wire 64. In some embodiments, the first wire 64 may be a coaxial wire to facilitate signal transmission.
In addition, the first antenna part 51 and the second antenna part 52 may be electrically connected by a second wire 65, and the second antenna part 52 and the second chip 82 may be electrically connected by a third wire 75. The wire is easy to bend, which can adapt to the complicated internal structure of the imaging device, which is more helpful to reduce the size of the imaging device. There may be various types of wires. In some embodiments, the second wire 65 may be a coaxial wire, and the third wire 75 may be a coaxial wire, which is convenience to facilitate signal transmission.
In the above-mentioned embodiment, the mounting part 2 may further include a housing and a base mounted in the housing. The first antenna 4 and the second antenna 5 may be fixed between the base and the housing.
More specifically, the mounting part 2 may include a base and a housing sleeved outside the base. The first antenna 4 and the second antenna 5 may be fixed between the base and the housing, thereby preventing the first antenna 4 and the second antenna 5 from being exposed to the mounting part 2 and being damaged, and improving the service life of the first antenna 4 and the second antenna 5.
In some embodiments, the first antenna 4 and the second antenna 5 may be fixed on the base, and a buffer may be disposed between the first antenna 4 and the housing, and between the second antenna 5 and the housing. The buffer may have a certain degree of elasticity, which can be filled in a gap between the first antenna 4 and the housing to enhance the fixing effect of the first antenna 4. At the same time, the buffer can reduce the impact of the first antenna 4 when the imaging device vibrate, thereby ensuring the normal operation of the first antenna 4.
Similarly, a buffer may also be disposed between the second antenna 5 and the housing. There may be various types of buffers, such as rubber, sponge, etc. In some embodiments, the buffer may include a foam, which has a lower cost.

When the imaging device is a tablet computer, the housing 1 may include a tablet computer housing, and the mounting part 2 may include a lens assembly, which can be used to capture images. The housing of the mounting part 2 may include a lens housing, the base may include a lens disposed in the lens housing, and the antenna 3 may be disposed between the lens housing and the lens. The lens housing may be made of non-metal materials, such as plastic, and the lens may be made of glass, such that the mounting part 2 can be made of non-metal materials. The antenna 3 may be disposed between the lens housing and the lens. More specifically, the antenna 3 may be fixed on the inner surface of the lens housing facing the lens, or on the outer surface of the lens facing the lens housing. Alternatively, one side of the antenna 3 may be fixedly connected to the lens housing, and the other side may be fixedly connected to the lens.
When the imaging device is a camera, the housing 1 may include a camera housing, and the mounting part 2 may include an eyepiece assembly for framing. The housing may include an eyepiece housing, the base may include an eyepiece disposed in the eyepiece housing, and the antenna 3 may be disposed between the eyepiece and the eyepiece housing. The eyepiece assembly can assist the user in framing, and it can include an eyepiece housing and an eyepiece. The eyepiece housing may be made of non-metal materials, such as plastic, and the eyepiece may be made of glass, such that the eyepiece assembly can be made of non-metal material. It should be understood that camera may also include a display screen, and both the display screen and the eyepiece assembly can be used for framing. When the camera is fixed on a trip or other places where the photographer is far away, the view can be viewed through the display screen, but when the photographer holds the camera, the view can be viewed through the eyepiece assembly, which is easy to operate. The antenna 3 may be disposed between the eyepiece and the eyepiece housing. More specifically, the antenna 3 may be fixed on the inner surface of the eyepiece housing facing the eyepiece, or on the outer surface of the eyepiece housing facing the eyepiece. Alternatively, one side of the antenna 3 may be fixedly connected to the eyepiece housing, and the other side may be fixedly connected to the eyepiece.
