Abstract
Description
Technical Field
[0001] The present application belongs to the field of communication technology, and specifically relates to an electronic device. Background Art
[0002] With the development of science and technology, the popularity of foldable electronic devices is increasing. Such electronic devices can obtain a larger display area in the unfolded state, and can reduce their own size in the folded state, making them easier for users to carry.
[0003] However, since foldable electronic devices require a hinge mechanism for driving the electronic devices to unfold or fold, the structural layout of the foldable electronic devices is compact and the free space is small. Moreover, when the foldable electronic device is in a folded state, the distance between the various components is small, resulting in a small clearance distance for the antenna set in the foldable electronic device, which affects the clearance environment of the antenna and thus affects the working performance of the antenna. Summary of the Invention
[0004] The purpose of the embodiments of the present application is to provide an electronic device that can solve the problem of poor antenna performance of electronic devices in the related art.
[0005] An embodiment of the present application provides an electronic device, including a first device body, a second device body, and a hinge mechanism, wherein:
[0006] The hinge mechanism includes a first connecting portion and a second connecting portion, the first device body is connected to the first connecting portion, the second device body is connected to the second connecting portion, and the first device body can rotate relative to the second device body to switch the electronic device between a folded state and an unfolded state;
[0007] At least a portion of the hinge mechanism serves as a first antenna radiator, or the hinge mechanism is provided with a first antenna radiator;
[0008] When the electronic device is in a folded state, a clearance opening is formed between the first connection portion and the second connection portion, and during the process of the electronic device switching from the folded state to the unfolded state, the clearance opening formed between the first connection portion and the second connection portion decreases.
[0009] In an embodiment of the present application, at least a portion of the structure of the hinge mechanism itself is directly used as the first antenna radiator, or the hinge mechanism directly sets the first antenna radiator. Moreover, when the electronic device is in a folded state, due to the appearance of the clearance opening, the clearance environment of the first antenna radiator is optimized, that is, the clearance distance is increased, and there are no metal parts within a certain distance range near the first antenna radiator to block its communication. Therefore, the clearance environment of the first antenna radiator is not affected by the folding of the electronic device, but is beneficial to improving the working performance of the first antenna radiator.
[0010] On the other hand, when the electronic device is in the folded state, the first device body and the second device body are in contact with each other, and the combination of the two is likely to excite the cavity mode, introducing interference within the working frequency band. The hinge mechanism is located at the edge of the first device body and the second device body, and the position of the first antenna radiator is far away from the area formed by the first device body and the second device body. Therefore, the first antenna radiator will not be affected by interference, thereby avoiding affecting the working performance of the first antenna radiator. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The following will be combined with the accompanying drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of this application.
[0033] The terms "first," "second," and the like in the specification and claims of this application are used to distinguish similar objects, and are not used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of this application can be implemented in an order other than that illustrated or described herein, and that the objects distinguished by "first," "second," and the like are generally of the same type, and do not limit the number of objects; for example, the first object can be one or more. In addition, the term "and / or" in the specification and claims refers to at least one of the connected objects, and the character " / " generally indicates that the objects connected are in an "or" relationship.
[0034] The electronic device provided in the embodiments of the present application is described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.
[0035] refer to Figures 1-13 The embodiment of the present application discloses an electronic device, which includes a first device body 100, a second device body 200 and a hinge mechanism 300. Figure 1-Figure 2 As shown, the hinge mechanism 300 is arranged at the edge of the first device body 100 and the second device body 200, and the hinge mechanism 300 is located between the first device body 100 and the second device body 200. The hinge mechanism 300 is used to connect the first device body 100 and the second device body 200 so that the electronic device can switch between a folded state and an unfolded state.
[0036] refer to Figure 3 、 Figure 5 and Figure 7As shown, the hinge mechanism 300 includes a first connection portion 320 and a second connection portion 330. The first device body 100 is connected to the first connection portion 320, and the second device body 200 is connected to the second connection portion 330. The first device body 100 can rotate relative to the second device body 200, thereby switching the electronic device between a folded state and an unfolded state. During the relative rotation of the first device body 100 and the second device body 200, the first connection portion 320 and the second connection portion 330 move relative to each other. Optionally, the first device body 100 can rotate relative to the second device body 200 about a rotation axis. The hinge mechanism 300 also includes a rotating shaft 310. The axis of the rotating shaft 310 is the rotation axis. The first device body 100 is rotationally connected to the rotating shaft 310 via the first connection portion 320, and the second device body 200 is rotationally connected to the rotating shaft 310 via the second connection portion 330. Specifically, the first connection portion 320 is rotationally connected to the rotating shaft 310, and the second connection portion 330 is rotationally connected to the rotating shaft 310. The first device body 100 can rotate relative to the second device body 200 about the rotation axis 310 to switch the electronic device between a folded state and an unfolded state. Optionally, the first connecting portion 320 and the second connecting portion 330 can both be provided with a sleeve ring, which is sleeved on the rotation axis 310 and can rotate relative to the rotation axis 310.
[0037] At least a portion of the hinge mechanism 300 serves as the first antenna radiator 400, or the hinge mechanism 300 is provided with the first antenna radiator 400. Optionally, the rotating shaft 310 may serve as the first antenna radiator 400, or other metal components in the hinge mechanism 300 other than the rotating shaft 310, the first connecting portion 320, and the second connecting portion 330 may serve as the first antenna radiator 400; or a metal component may be separately provided outside the hinge mechanism 300 as the first antenna radiator 400. Moreover, when the electronic device is in the folded state, a clearance opening 350 is formed between the first connecting portion 320 and the second connecting portion 330. During the process of switching the electronic device from the folded state to the unfolded state, the clearance opening formed between the first connecting portion 320 and the second connecting portion 330 is reduced. When the electronic device is in the unfolded state, there may be a gap between the first connecting portion 320 and the second connecting portion 330, or the first connecting portion 320 and the second connecting portion 330 may be in direct contact. Optionally, refer to Figure 3 and Figure 4 As shown, the first connection part 320 and the second connection part 330 can be flexible connection parts. During the folding process of the electronic device, a portion of the first connection part 320 can be bent relative to the first device body 100, and a portion of the second connection part 330 can be bent relative to the second device body 200, thereby forming a clearance opening 350 between the bent portion of the first connection part 320 and the bent portion of the second connection part 330.
[0038] Optionally, the rotating shaft 310 may include a first rotating shaft and a second rotating shaft, the first rotating shaft and the second rotating shaft may be connected to each other through gears, and the first connecting part 320 is rotationally connected to the first rotating shaft, the second connecting part 330 is rotationally connected to the second rotating shaft, and the clearance opening 350 is located between the first rotating shaft and the second rotating shaft.
[0039] In the embodiments of the present application, at least a portion of the hinge mechanism 300 itself is directly used as the first antenna radiator 400, or the hinge mechanism 300 is directly provided with the first antenna radiator 400. Furthermore, when the electronic device is folded, the presence of the clearance opening 350 optimizes the clearance environment of the first antenna radiator 400. Specifically, the clearance distance is increased, and no metal components within a certain distance of the first antenna radiator 400 obstruct its communication. Therefore, the clearance environment of the first antenna radiator 400 is not affected by the folding of the electronic device, but rather improves the operating performance of the first antenna radiator 400. Furthermore, the presence of the first antenna radiator 400 can reduce the number of antennas provided on the first device body 100 and the second device body 200, thereby reducing the overall weight of the electronic device.
[0040] On the other hand, when the electronic device is in a folded state, the first device body 100 and the second device body 200 are in contact with each other, and the combination of the two is likely to excite the cavity mode, introducing interference within the working frequency band. The hinge mechanism 300 is located at the edge of the first device body 100 and the second device body 200, and the position of the first antenna radiator 400 is far away from the area formed by the first device body 100 and the second device body 200. Therefore, the first antenna radiator 400 will not be affected by interference, thereby avoiding affecting the working performance of the first antenna radiator 400.
[0041] In an optional embodiment, the hinge mechanism 300 further includes a cover plate 340, which is movably connected to the first device body 100 and the second device body 200, and a portion of the cover plate 340 serves as the first antenna radiator 400, or as Figure 3 and Figure 4As shown, the cover plate 340 is a metal cover plate, and the cover plate 340 serves as the first antenna radiator 400. That is, the entire cover plate 340 serves as the first antenna radiator 400. The metal material of the cover plate 340 is not limited. Optionally, the first device body 100 can rotate relative to the second device body 200 about the rotation axis. During the relative rotation of the first and second device bodies 100 and 200, the position of the cover plate 340 relative to the rotation axis or the rotating shaft 310 remains unchanged. In this way, the cover plate 340 not only prevents the rotating shaft 310, the first connecting portion 320, and the second connecting portion 330 from being exposed, improving the appearance of the electronic device, but also serves as the first antenna radiator 400, thereby improving the communication performance of the electronic device. In the latter embodiment, the metal cover plate directly serves as the first antenna radiator 400, which helps increase the volume of the first antenna radiator 400 and the communication area, further improving the communication performance of the electronic device.
[0042] Optionally, when the electronic device is in the folded state, the first antenna radiator 400 is located on the inner side of the clearance opening 350, where the inner side of the clearance opening 350 refers to the side facing the interior of the electronic device. In this way, the first antenna radiator 400 is relatively close to the interior of the electronic device and is easily blocked from communication by metal components such as the hinge 310, which is not conducive to improving the operating performance of the first antenna radiator 400. Therefore, in another embodiment, when the electronic device is in the folded state, the first antenna radiator 400 is located on the outer side of the clearance opening 350, where the outer side of the clearance opening 350 refers to the side facing away from the interior of the electronic device. In this way, the first antenna radiator 400 is closer to the exterior of the electronic device, and the clearance environment of the first antenna radiator 400 is better, which is conducive to improving the operating performance of the first antenna radiator 400.
[0043] Because the cover 340 is metal, it is relatively heavy, which in turn increases the overall weight of the electronic device. To address this issue, the cover 340 is provided with a first groove a filled with a first non-metallic medium 341. When the electronic device is folded, the first groove a faces the clearance opening 350, i.e., the opening of the first groove a faces the clearance opening 350. Optionally, the first non-metallic medium 341 can be plastic or another non-metallic medium. Since the first non-metallic medium 341 is lighter than metal, filling the first groove a with the first non-metallic medium 341 ensures the support performance of the cover 340 while reducing the overall weight of the cover 340, and thus the weight of the electronic device. Furthermore, since the first groove a faces the clearance opening 350, when the electronic device is folded, the clearance distance to the first antenna radiator 400 is increased, creating a good clearance environment and improving the performance of the first antenna radiator 400.
[0044] In an optional embodiment, as Figure 5 and Figure 6 As shown, the hinge mechanism 300 also includes a cover plate 340, which is movably connected to the first device body 100 and the second device body 200. A first antenna radiator 400 is provided on the outer surface of the cover plate 340. The cover plate 340 is a non-metallic structural member. Optionally, the cover plate 340 may be a plastic structural member or another non-metallic structural member. The first antenna radiator 400 is provided on the outer surface of the cover plate 340. The outer surface here refers to the side of the cover plate 340 facing away from the interior of the electronic device. When the electronic device is folded, the cover plate 340 is located outside the clearance opening 350, that is, the first antenna radiator 400 is located on the side of the cover plate 340 facing away from the clearance opening 350. Optionally, after the cover plate 340 is formed, the first antenna radiator 400 can be directly formed on the surface of the cover plate 340 using laser technology, simplifying the assembly process.
[0045] Since the weight of the non-metallic structure is less than that of the metal structure, the present embodiment can further reduce the weight of the cover plate 340 while ensuring the supporting performance of the cover plate 340, thereby reducing the weight of the electronic device. At the same time, the cover plate 340 will not interfere with the first antenna radiator 400, thereby improving the working performance of the first antenna radiator 400.
[0046] In an optional embodiment, the cover 340 has a second groove b filled with a second non-metallic medium 342. When the electronic device is folded, the second groove b faces the clearance opening 350, i.e., the opening of the second groove b faces the clearance opening 350. Optionally, the material of the second non-metallic medium 342 is different from that of the first non-metallic medium 341, and the density of the second non-metallic medium 342 is lower than that of the first non-metallic medium 341. The first non-metallic medium 341 and the second non-metallic medium 342 may be made of different types of plastic. Filling the second groove b with the second non-metallic medium 342 can further reduce the overall weight of the cover 340, thereby reducing the weight of the electronic device. Furthermore, because the second groove b faces the clearance opening 350, the clearance distance of the first antenna radiator 400 is increased when the electronic device is folded, creating a good clearance environment and improving the performance of the first antenna radiator 400.
[0047] In an optional embodiment, the first device body 100 can rotate around the rotation axis relative to the second device body 200, and the extension direction of the first antenna radiator 400 can intersect with the extension direction of the rotation axis. In this way, since the space occupied by the hinge mechanism 300 is limited, the tilting of the first antenna radiator 400 relative to the rotation axis will affect its own extension length, which is not conducive to improving the working performance of the first antenna radiator 400. Therefore, in another embodiment, the first antenna radiator 400 extends along the extension direction of the rotation axis. In this way, the extension length of the first antenna radiator 400 is limited and reduced, and the extension length of the first antenna radiator 400 can be increased, which is conducive to improving the working performance of the first antenna radiator 400; moreover, the radiation direction of the first antenna radiator 400 to the human body tends to be perpendicular to the direction of the rotation axis, such as Figure 8 The area corresponding to the dotted box on the side of point A is the radiation area of the first antenna radiator 400, so the possibility of the human body contacting the radiation area of the first antenna radiator 400 is small, which can reduce the radiation to the human body to a certain extent.
[0048] In an optional embodiment, the first antenna radiator 400 is an integrated structure, and the first antenna radiator 400 is a single-frequency antenna; or Figure 9 As shown, the first antenna radiator 400 includes at least two radiating portions 410, each spaced apart along the extension direction of the rotation axis, with a gap 430 defined between adjacent radiating portions 410. In the latter embodiment, each radiating portion 410 can be configured as a different antenna configuration as needed, allowing each radiating portion 410 to have different frequencies, allowing the first antenna radiator 400 to function as a multi-band antenna. Alternatively, each radiating portion 410 can be a monopole antenna, a loop antenna, or the like.
[0049] In the solution of this application, if Figure 8 As shown, the electronic device may further include a second antenna radiator 500, which is disposed on the edge of at least one of the first device body 100 and the second device body 200. Optionally, there may be at least two second antenna radiators 500, each of which is disposed at intervals. Specifically, in the folded state, the electronic device includes an upper end face and a lower end face that face away from each other, as well as a left end face and a right end face that face away from each other, wherein the hinge mechanism 300 is disposed on the left end face, and each of the second antenna radiators 500 may be distributed on the upper end face, the lower end face, and the right end face. Figure 8 The area corresponding to the dotted frame on the side of the second antenna radiator 500 is the radiation area of the second antenna radiator 500. Optionally, the first antenna radiator 400 and the second antenna radiator 500 can work simultaneously, or they can work in a switched manner.
[0050] In this way, the second antenna radiator 500 cooperates with the first antenna radiator 400 to communicate, which is beneficial to improving the communication performance of the electronic device; moreover, the second antenna radiator 500 is relatively close to the outside of the electronic device, and the clearance environment of the second antenna radiator 500 is better, which is beneficial to improving the working performance of the second antenna radiator 500.
[0051] In an optional embodiment, when the electronic device is in a folded state, the second antenna radiator 500 is in a working state. However, since the first device body 100 and the second device body 200 are combined to easily excite the cavity mode, interference is introduced into the working frequency band, resulting in a reduction in the working performance of the second antenna radiator 500. At the same time, when the electronic device is in an unfolded state, the first antenna radiator 400 is in a working state. However, since the first connecting portion 320 and the second connecting portion 330 jointly close the clearance opening 350 at this time, the clearance distance of the first antenna radiator 400 is small, resulting in a reduction in the working performance of the first antenna radiator 400.
[0052] Therefore, in another embodiment, when the electronic device is in the folded state, the first antenna radiator 400 is in the operative state, while the second antenna radiator 500 is in the inoperative state. When the electronic device is in the unfolded state, the second antenna radiator 500 is in the operative state, while the first antenna radiator 400 is in the inoperative state. In other words, when the electronic device is in the folded state, the clearance environment of the second antenna radiator 500 is easily affected, which is not conducive to the operation of the second antenna radiator 500. However, due to the presence of the clearance opening 350, the clearance distance of the first antenna radiator 400 is larger, and the clearance environment is good. Therefore, in this case, only the first antenna radiator 400 operates more effectively. Similarly, when the electronic device is in the unfolded state, the clearance environment of the second antenna radiator 500 is good, while the first antenna radiator 400 is easily blocked by the first connecting portion 320 and the second connecting portion 330 from communicating. This is not conducive to the operation of the first antenna radiator 400. Therefore, in this case, only the second antenna radiator 500 operates more effectively.
[0053] With this arrangement, users can switch to different antennas according to the form of the electronic device, thereby reducing the power consumption of the electronic device and helping to extend the battery life of the electronic device.
[0054] The user can manually switch the state of the first antenna radiator 400 and the second antenna radiator 500 according to the form of the electronic device, but the manual switching action is slow and the switching efficiency is low. Figure 11As shown, the electronic device further includes a control module 610 and a detection module 620. The control module 610 and the detection module 620 are disposed in at least one of the first device body 100 and the second device body 200. The detection module 620, the first antenna radiator 400, and the second antenna radiator 500 are respectively in communication with the control module 610. The detection module 620 is configured to detect the electronic device's configuration, that is, whether the electronic device is in a folded or unfolded state. The control module 610 is configured to control the states of the first antenna radiator 400 and the second antenna radiator 500 based on the electronic device's configuration. In this manner, the detection module 620 and the control module 610 are utilized to automatically switch between the first antenna radiator 400 and the second antenna radiator 500, achieving high switching efficiency.
[0055] Optionally, the detection module 620 can be a distance sensor, which detects the change in distance between a certain position of the first device body 100 and a certain position of the second device body 200 through the distance sensor to identify whether the electronic device is in a folded state or an unfolded state. When the distance value detected by the distance sensor is less than the first preset value, it indicates that the electronic device is in a folded state. At this time, the control module 610 controls the first antenna radiator 400 to work. When the distance value detected by the distance sensor is greater than the second preset value, it indicates that the electronic device is in an unfolded state. At this time, the control module 610 controls the second antenna radiator 500 to work. Of course, the detection module 620 can also be a capacitive sensor or other detection element. In short, the shape of the electronic device is identified based on the change in the measured value detected by the detection module 620. The control module 610 can be a PLC (Programmable Logic Controller) or a single-chip microcomputer.
[0056] In an optional embodiment, when the electronic device is in multi-antenna operating mode, both the first antenna radiator 400 and the second antenna radiator 500 are in operation. Alternatively, when the electronic device is folded, both the first antenna radiator 400 and the second antenna radiator 500 are in operation. In this way, the first antenna radiator 400 and the second antenna radiator 500 can form a MIMO antenna system (i.e., a multiple-input, multiple-output system), which improves communication performance and, in turn, enhances the user experience.
[0057] In an optional embodiment, if Figure 8As shown, the electronic device further includes a camera 700, which is disposed on the top of at least one of the first device body 100 and the second device body 200. The first antenna radiator 400 is disposed near the top, with the upper end surface referred to above being the top. Specifically, the hinge 310 has a first end and a second end, with the first end of the hinge 310 being adjacent to the top. A first preset distance exists between the first antenna radiator 400 and the first end of the hinge 310, and a second preset distance exists between the first antenna radiator 400 and the second end of the hinge 310, with the first preset distance being less than the second preset distance. When a user uses an electronic device, their hands typically grip the bottom of the device, and their head may only contact the top of the device. The first antenna radiator 400 is disposed in the middle of the hinge 310 and relatively close to the camera 700. Therefore, the human body is kept away from the radiation area of the first antenna radiator 400, reducing radiation exposure to the human body.
[0058] In the solution of this application, if Figure 12-13 As shown, the first device body 100 can rotate about the rotation axis relative to the second device body 200, and the first antenna radiator 400 is provided with a slit 420, which extends along the extension direction of the rotation axis. In this case, the first antenna radiator 400 is a slot antenna. Optionally, when the cover plate 340 is a metal cover plate and the metal cover plate serves as the first antenna radiator 400, the metal cover plate is provided with a slit 420, and the slit 420 can be connected to the first groove a; when the cover plate 340 is provided with the first antenna radiator 400, the first antenna radiator 400 is provided with a slit 420. In this way, by providing the slit 420, the volume of the first antenna radiator 400 can be reduced, further reducing the weight of the first antenna radiator 400, thereby reducing the weight of the electronic device.
[0059] In an optional embodiment, there is one slit 420, or the first antenna radiator 400 is provided with at least two slits 420, each slit 420 spaced apart along the extension direction of the rotation axis, and each slit 420 has a different length. Specifically, each slit 420 includes a first slit and a second slit, the first slit having a length of L1 and the second slit having a length of L2, where L1 is less than L2, and the frequency of the antenna portion corresponding to the first slit is higher than the frequency of the antenna portion corresponding to the second slit. In this way, by providing slits 420 of different lengths, the operating frequency of the first antenna radiator 400 can be adjusted.
[0060] In an optional embodiment, the electronic device further includes a reactance switching component 800, which is disposed in at least one of the first device body 100 and the second device body 200. The reactance switching component 800 is electrically connected to the first antenna radiator 400 to adjust the frequency range of the first antenna radiator 400. Optionally, the reactance switching component 800 may include a selector switch and a component with different reactance values, such as a capacitor or an inductor. At least one of the capacitor or inductor may be provided. The selector switch is electrically connected to the first antenna radiator 400 and can selectively connect to either the capacitor or the inductor. Specifically, when the frequency of the first antenna radiator 400 needs to be lowered, the selector switch can select the inductor for connection, thereby reducing the inductor's inductance. When the frequency of the first antenna radiator 400 needs to be raised, the selector switch can select the capacitor for connection, thereby reducing the capacitor's capacitance. In summary, the reactance switching component 800 enables frequency switching of the first antenna radiator 400, enabling precise frequency modulation of the first antenna radiator 400.
[0061] In actual application, a slit 420 of appropriate length is first opened on the first antenna radiator 400 to initially tune the frequency of the first antenna radiator 400 so that the operating frequency of the first antenna radiator 400 is within a certain frequency range, and then the first antenna radiator 400 is precisely tuned through the reactance switching component 800.
[0062] In this embodiment, there are at least two slits 420, spaced apart along the axis of rotation. The lengths of the slits 420 vary, thereby forming an antenna with a wider range of frequency bands. Furthermore, the reactance switching component 800 is located between adjacent slits 420. This minimizes the distance between the reactance switching component 800 and each adjacent slit 420, allowing the reactance switching component 800 to precisely tune the frequency of the antenna portion corresponding to each adjacent slit 420.
[0063] The electronic device disclosed in the embodiment of the present invention can be a smart phone, a tablet computer, an e-book reader or a wearable device. Of course, the electronic device can also be other devices, and the embodiment of the present invention does not limit this.
[0064] The embodiments of the present application are described above in conjunction with the accompanying drawings, but the present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of this application, ordinary technicians in this field can also make many forms without departing from the purpose of this application and the scope of protection of the claims, all of which are within the protection of this application.
