Detailed Description

With the development of communication technology, more and more electronic devices are equipped with antennas, and antennas are indispensable components of many electronic devices, especially mobile internet devices such as smart phones, tablet computers, and notebook computers.

With the increasing dependence of people's daily life on electronic devices, it is necessary to improve the convenience of electronic devices, for example, to reduce the volume and weight of electronic devices, i.e., it is a trend of developing electronic devices to make electronic devices light and thin. The ultra-thin machine body enables the hardware built-in space of the electronic equipment to be quite limited, the space reserved for the antenna is smaller and smaller, electronic elements in the machine body are highly integrated, and therefore the occupied volume of the antenna is reduced. Therefore, how to install an antenna in a slim housing so that the antenna can exhibit high efficiency is a hot point problem in antenna design.

In order to meet the demands of the public, the appearance of electronic devices is also an important factor for users, for example, various electronic products with metallic appearance are deeply attractive to consumers. However, the fully-enclosed metal housing can shield radio waves generated by the antenna of the electronic device, so that the electronic device with the fully-enclosed metal housing has higher design requirements on the antenna.

In order to solve the aforementioned problem of light and thin electronic devices, the prior art includes: the antenna of the electronic device is highly integrated, for example, one antenna can be made into a WIFI (Wireless Fidelity, WIFI), BT (Bluetooth, BT), GPS (Global Positioning System, GPS), FM (Frequency Modulation, FM) four-in-one antenna, that is, 4 functions can be realized by the same antenna, although the antenna is highly integrated, the result of the high integration is that once the antenna fails, all signals are completely interrupted, that is, all functions are integrated on one antenna, and if the antenna fails, all functions are interrupted.

In order to solve the aforementioned problem of appearance of the electronic device, the prior art includes: the gap is formed in the top or the side face of the notebook computer with the full metal shell to effectively disperse antenna radiation, otherwise, most of the antenna radiation is absorbed by the metal shell, but the problem of high callback signal loss exists by adopting the mode, and the defect of imperfect appearance structure can be caused by the gap in the full metal shell although the electronic equipment is made into the full metal shell.

In order to solve the above technical problems, the technical solution in the embodiments of the present invention has the following general idea:

an embodiment of the present invention provides an electronic device, including: a first body; a second body; the first body and the second body can be connected through the rotating shaft and can relatively rotate through the rotating shaft; the rotating shaft comprises a first structure, the first structure comprises a metal antenna and an axis, and the metal antenna is sleeved on the axis; the electronic equipment can transmit and receive signals through the metal antenna. The invention provides the electronic equipment with the innovative antenna, namely, the rotating shaft body is used as the antenna to send and receive signals, so that the cost is saved, and the antenna does not need to be highly integrated into the electronic equipment, so that the electronic equipment is light and thin.

In addition, in the electronic device provided by the embodiment of the invention, because the rotating shaft is used as the antenna, the first body and the second body can be made into the metal shell, so that the signal transmitted and received by the antenna is not required to be shielded by the metal shell, the appearance of the electronic device is improved, and the electronic device is attractive to users who like metal texture.

Fig. 1 is a block diagram of an electronic device according to an embodiment of the present invention. As can be seen from fig. 1, the electronic device includes: the device comprises a first body 1, a second body 2 and a rotating shaft 3. Wherein, first body 1 and second body 2 are connected with pivot 3 respectively, and first body 1 and second body 2 can be through pivot 3 relative rotation.

The electronic equipment provided by the embodiment of the invention can be a traditional notebook computer, the traditional notebook computer is provided with a display body and a keyboard body, and the display body and the keyboard body are rotatably connected through a rotating shaft. Corresponding to the technical solution of the embodiment of the present invention, the first body may be a display body of a notebook computer, the second body may be a keyboard body of the notebook computer, and the first body and the second body are rotatably connected through a rotating shaft.

Of course, the electronic device provided by the embodiment of the invention can also be a tablet computer and notebook computer two-in-one electronic device, when the tablet computer part is separated from the host computer part, the electronic device can be independently used as the tablet computer, and if the tablet computer part and the host computer part are combined together, the electronic device can be used as a common notebook computer. Corresponding to the technical solution of the embodiment of the present invention, the first body may be a tablet computer, the second body may be a notebook computer, and the first body and the second body are rotatably connected through a rotating shaft. Of course, the electronic device provided in the embodiment of the present invention may also be other foldable electronic devices having a rotating shaft.

With continued reference to fig. 1, the hinge 3 of the electronic device includes a first structure 31. The first structure 31 may be used as an antenna, i.e. the electronic device may transmit and receive signals through the first structure 31 on the shaft 3.

Fig. 2 is a structural diagram of the first structure 31 of the spindle 3. As shown in fig. 2, the first structure 31 includes a metal antenna 311 and a shaft 312, wherein the metal antenna 311 is sleeved on the shaft 312; the electronic device can transmit and receive signals through the metal antenna 311. The metal antenna 311 may be fixedly connected to the first body 1 or the second body 2, so that the first body 1 or the second body 2 relatively rotates around the axis 312 through the metal antenna 311.

Alternatively, the metal antenna 311 on the first structure 31 may not be limited to a metal sheet, but may also be an antenna capable of transmitting and receiving signals, such as a Printed Circuit Board (PCB) antenna.

Alternatively, the thickness of the metal antenna 311 in the first structure 31 may be determined according to actual conditions. If a larger thickness is required and a metal material is saved, a layer of other material, such as an insulating material, may be first sleeved on the shaft core 312, and a layer of metal material may be coated on the insulating material, so that the metal material may be used as an antenna. Of course, the width of the metal antenna 311 may be determined according to actual conditions.

Alternatively, the number of the metal antennas 311 may be one, two, or even more. If there is only one metal antenna 311, the first connection mode of the first body 1 and the second body 2 can be as shown in fig. 3, that is, the first body 1 is fixedly connected to two ends of the shaft center 312, and a certain gap is formed between the first body 1 and the shaft center 312, the metal antenna 311 can be a hollow cylinder, and is sleeved on the shaft center 312, and the metal antenna 311 is fixedly connected to the second body 2, and when the second body 2 rotates relative to the first body 1, the metal antenna 311 can be driven to rotate around the shaft center 312.

If there is only one metal antenna 311, the second connection mode of the first body 1 and the second body 2 may be that the second structure 32 may be further disposed on the rotating shaft 3. The second structure 32 may be an insulating structure, and the second structure 32 may be sleeved on the shaft 312. Referring to fig. 4, the first body 1 is fixedly connected to the metal antenna 311, the second body 2 is fixedly connected to the second structure 32, when the user rotates the first body 1 and the second body 2, the first body 1 drives the metal antenna 311 to rotate around the axis 312, and the second body 2 drives the second structure to rotate around the axis 312. Fixing means may be provided at both ends of the shaft 312 to fix the position of the shaft 312.

If there is only one metal antenna 311, the third connection mode of the first body 1 and the second body 2 may be that the second structure 32 may be further disposed on the rotating shaft 3. The second structure 32 may be an insulating structure, and the second structure 32 may be sleeved on the shaft 312. Referring to fig. 5, the first body 1 is fixedly connected to two ends of the shaft 312, and a gap is formed between the first body 1 and the shaft 312, the metal antenna 311 and the second structure 32 may be hollow cylinders sleeved on the shaft 312, and both the metal antenna 311 and the second structure 32 are fixedly connected to the second body 2, so that the second body 2 can drive the metal antenna 311 and the second structure 32 to rotate around the shaft 312 simultaneously when rotating relative to the first body 1.

If there are two metal antennas 311, the second structure 32 may be disposed between two adjacent metal antennas 311. Under the isolation of the second structure 32, two adjacent metal antennas 311 can be used as separate antennas respectively. If there are a plurality of metal antennas 311, the number of the second structures 32 may also be multiple, and in order to ensure that each metal antenna 311 can be used as a single antenna, each two adjacent metal antennas 311 may be isolated by the second structures 32, that is, the metal antennas 311 and the second structures 32 are alternately disposed on the shaft center 312, as shown in fig. 2.

Alternatively, if cost is saved, the second structure 32 may be omitted, that is, if there are two metal antennas 311, a certain gap may be left between the two metal antennas 311, so that the two metal antennas 311 may be separated. If there are a plurality of metal antennas 311, the second structure 32 may be disposed between two metal antennas 311, and a gap is left between two other metal antennas 311. For example, if the signal interference is strong during the process of transmitting and receiving signals by the two metal antennas 311, the second structure 32 may be disposed between the two metal antennas 311, and if the signal interference is weak, only a gap may be left between the two metal antennas 311.

Alternatively, as mentioned above, the metal antenna 311 on each first structure 31 on the rotating shaft 3 can be used as a separate antenna. The first possible scenario is: the frequency bands of the signals that can be transmitted and received by any two metal antennas 311 on the rotating shaft 3 are not completely the same. For example, for an electronic device that transmits and receives a single frequency band, such as 50MHz to 60MHz, only one first structure 31 may be disposed on the rotating shaft 3, and signals of 50MHz to 60MHz may be transmitted and received through the first structure 31. However, with the increase of functions of electronic devices, it is increasingly necessary to transmit and receive signals of multiple different frequency bands, so as to avoid interference easily occurring when the same antenna receives signals of different frequency bands at the same time. A plurality of first structures 31 may be disposed on the electronic device hinge 3, and each first structure 31 may transmit and receive signals of one frequency band. For example, two first structures 31 are disposed on the rotating shaft 3, the metal antenna 311 on one of the first structures 31 may be used to transmit and receive signals in a frequency band of 50MHz to 60MHz, and the metal antenna 311 on the other first structure 31 may be used to transmit and receive signals in a frequency band of 60MHz to 70 MHz.

Alternatively, the metal antenna 311 on each first structure 31 on the rotating shaft 3 may be used as a separate antenna. A second possible scenario is: any two metal antennas 311 on the shaft 3 can perform different functions. For example, if two first structures 31 are disposed on the electronic device hinge 3, one of the first structures 31 is used for receiving signals, and the other first structure 31 is used for transmitting signals. For example, one of the first structures 31 may be configured as a main set antenna, and the other first structure 31 may be configured as a diversity antenna. Therefore, the electronic equipment sends signals through the main set antenna and receives the signals through the diversity antenna, and the situation that the same antenna generates signal interference in the process of sending and receiving signals simultaneously is avoided.

Alternatively, the metal antenna 311 on each first structure 31 on the rotating shaft 3 may be used as a separate antenna. A third possible scenario is: any two metal antennas 311 on the shaft 3 can be used for transceiving different types of signals. For example, it is assumed that four first structures 31 are disposed on the rotating shaft 3, wherein a first structure 31 is used for transceiving WIFI signals, a second structure 31 is used for transceiving BT signals, a third structure 31 is used for transceiving GPS signals, and a fourth structure 31 is used for transceiving FM signals. Of course, it may be possible to integrate multiple types of signals into one first structure 31, for example, the first structure 31 may be used for transceiving both WIFI signals and BT signals. Of course, if there is only one first structure 31, the aforementioned four antennas may be integrated into the one first structure 31, that is, the metal antenna 311 on the first structure 31 is configured as a WIFI & BT & GPS & FM four-in-one antenna.

The three possible cases can be used alone or in combination. For example, two first structures 31 may be provided, wherein one first structure 31 is used as a two-in-one antenna for transceiving WIFI signals and BT signals in the frequency band of 50MHz to 60MHz, and the other first structure 31 is used as a two-in-one antenna for transceiving FM signals and GPS signals in the frequency band of 60MHz to 70 MHz.

As apparent from the above description, as functions of electronic devices are increased, types, frequency bands, and the like of signals transmitted and received by the electronic devices through the antennas are increased. If all the functions are integrated into one antenna, the design cost is high and the damage effect is large in case of failure. Through the electronic equipment with the inventive antenna provided by the embodiment of the invention, a person skilled in the art can set the first structures on the rotating shaft of the electronic equipment according to actual requirements, namely the number of the metal antennas, and set different functions for different metal antennas, all the different functions are not required to be integrated into one antenna, the design cost is low, and if one metal antenna fails, the normal use of other metal antennas is not influenced.

Alternatively, the metal antenna 311 on the first structure 31 may be supplied with current, so that the first structure 31 on the rotating shaft 3 may be used as an antenna. One of the ways of providing the current to the metal antenna 311 may be that the electronic device may further include: a circuit board (not shown). The circuit board may be disposed in the second body 2 or the first body 1. The circuit board is connected with the metal antenna 311 on the rotating shaft 3 through a radio frequency cable to supply power to the metal antenna 311. Assuming that the circuit board is disposed inside the second body 2, as mentioned above, the metal antenna 311 may be fixedly connected to the second body, as shown in fig. 5, in this case, the feeding point of the metal antenna 311 may be connected to the circuit board through a radio frequency cable, and both the circuit board and the radio frequency cable may be disposed inside the second body 2, and when the electronic device operates, the current is provided to the metal antenna 311 through the feeding point through the circuit board and the radio frequency cable.

Alternatively, as mentioned above, each first structure 31 on the rotating shaft 3 can be used as an independent antenna, so a circuit board can be separately provided for each metal antenna 311 on the first structure 31. That is, a plurality of circuit boards may be disposed in the first body 1 or the second body 2 of the electronic device, and one circuit board corresponds to one metal antenna 311, so that each metal antenna 311 may be correspondingly connected to the circuit board located in the first body 1 or the second body 2 of the electronic device, so that each metal antenna 311 may be used independently. Of course, if the functions of the metal antennas 311 on two first structures 31 are similar, the two metal antennas 311 can be connected to a circuit board together. In summary, the number of circuit boards may be determined by those skilled in the art according to actual situations, and the present invention is not particularly limited.

In summary, since the antenna structure of the conventional electronic device is disposed inside the electronic device, if the electronic device is disposed in an all-metal housing, the electronic device shields signals generated by the antenna and affects the transmission and reception of the signals, so that the electronic device cannot be made into an all-metal housing, which is a great obstacle to improving the aesthetic appearance of the electronic device. The antenna structure of the electronic device provided by the embodiment of the invention is not arranged in the electronic device, but the rotating shaft of the electronic device is arranged as the antenna, and the antenna structure is arranged outside the electronic device and is not arranged in the electronic device, so that the outer shell of the electronic device can be arranged into an all-metal structure, namely, the first body of the electronic device is provided with a metal shell, and the second body of the electronic device is provided with a metal shell.

Taking a notebook computer with the electronic device being a two-in-one display body and a keyboard body as an example, the rotating shaft of the notebook computer is used as an antenna, and signals can be transmitted and received through the antenna structure on the rotating shaft no matter how the display body and the keyboard body of the electronic device rotate. And, because antenna structure sets up in electronic equipment's outside, consequently electronic equipment's shell body can set up to all metal casing, and the shell body that shows the body and the shell body of keyboard body can all set up to all metal structure for example, has improved notebook computer's pleasing to the eye, to the user who likes metallic feel, has amazing power of not being small.

Of course, the electronic device further includes a processor, which may be specifically a central processing unit, an Application Specific Integrated Circuit (ASIC), one or more Integrated circuits for controlling program execution, a hardware Circuit developed by using a Field Programmable Gate Array (FPGA), or a baseband processor.

Optionally, the processor may include at least one processing core.

Optionally, the electronic device further includes a Memory, where the Memory may include a Read Only Memory (ROM), a Random Access Memory (RAM), and a disk Memory. The memory is used for storing data required by the processor during operation. The number of the memories is one or more.
