Abstract
Description
Technical Field
[0001] The present disclosure relates to the technical field of electronic products, and in particular to an electronic device. Background Art
[0002] With the development of smart terminals, various retractable screen electronic devices have emerged. Among them, the scroll screen electronic device, as one of the retractable screen electronic devices, is favored by consumers. Since the internal space of existing electronic devices is quite compact, the scroll screen electronic device usually opens a break on the metal frame to radiate the antenna signal.
[0003] However, the roll-up screen electronic device usually consists of a fixed part and a telescopic part, and the fixed part and the telescopic part need to have the fracture respectively. When the roll-up screen electronic device is in a retracted state, the fractures of the fixed part and the telescopic part are aligned, so the antenna has a better radiation effect. When the roll-up screen electronic device is in an extended state, since the positions of the fractures of the fixed part and the telescopic part change, the resonant frequency of the antenna is easily changed, which leads to the problem of reduced antenna performance. Summary of the invention

[0006] The feed source is electrically connected to the first segment, and the feed source, the first conductive frame and the second conductive frame together form a target antenna;
[0007] When the electronic device is in the retracted state, the first break is aligned with the second break; when the electronic device is in the extended state, at least a portion of the first break is opposite to the first conductive frame;
[0008] The first resonant frequency is smaller than the second resonant frequency, the first resonant frequency is the resonant frequency of the target antenna when the electronic device is in a retracted state, and the second resonant frequency is the resonant frequency of the target antenna when the electronic device is in an extended state.
[0009] In a second aspect, an embodiment of the present disclosure provides an electronic device, comprising a first frame, a second frame, and a feed source, wherein the first frame can be extended or retracted relative to the second frame, so that the electronic device can be switched between an extended state and a retracted state; the first frame comprises a first conductive frame, the second frame comprises a second conductive frame, the first conductive frame and the second conductive frame are stacked, and the first conductive frame is located outside the second conductive frame, the second conductive frame comprises a first segment and a second segment, a first break is formed between the first segment and the second segment, and a second break is provided on the first conductive frame;
[0010] The feed source is electrically connected to the first segment, and the feed source, the first conductive frame and the second conductive frame together form a target antenna;
[0011] When the electronic device is in the retracted state, the first break is aligned with the second break; when the electronic device is in the extended state, the first conductive frame extends from one side of the second segment relative to the second frame, the orthographic projection of the first end of the first conductive frame on the second conductive frame is located in the second segment, and the orthographic projection of the first end on the second conductive frame is located at a position other than the second end of the second segment, the first end is an end of the first conductive frame close to the first segment, and the second end is an end of the second segment facing the first segment;

[0013] In the disclosed embodiment, when the electronic device is in the unfolded state, the resonant frequency of the target antenna will be higher due to the reduction of the antenna radius. By making at least a portion of the first break opposite to the first conductive frame, the antenna signal fed into the first segment can be more strongly coupled to the first frame, thereby making the resonant frequency of the target antenna appropriately shifted toward the low-frequency direction, which is conducive to alleviating the problem of the high resonant frequency of the target antenna when it is in the unfolded state, and further helps to improve the antenna performance of the target antenna.

[0023] The following will be combined with the drawings in the embodiments of the present disclosure to clearly describe the technical solutions in the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present disclosure are within the scope of protection of the present disclosure.
[0024] The terms "first", "second", etc. in the specification and claims of the present disclosure are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable when appropriate, so that the embodiments of the present disclosure can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally of the same type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.
[0025] The electronic device provided by the embodiment of the present disclosure is described in detail below through specific embodiments and application scenarios in conjunction with the accompanying drawings.
[0026] See also Figure 1-2 It is a schematic diagram of the structure of the scroll screen electronic device in the retracted state and the extended state in the related art. It can be seen that when the scroll screen electronic device is in the retracted state, the outer frame of the first frame 100 overlaps with the outer frame of the second frame 200. At this time, the antenna radius is the sum of the cross-sectional area of the outer frame of the first frame 100 and the cross-sectional area of the outer frame of the second frame 200. When the scroll screen electronic device is in the extended state, the positions of the outer frame of the first frame 100 and the outer frame of the second frame 200 are relatively staggered. At this time, the antenna radius is the cross-sectional area of the outer frame of the second frame 200. After the scroll screen electronic device switches from the retracted state to the extended state, the radius of the antenna decreases. Therefore, the capacitance of the antenna input impedance becomes smaller, which leads to a high resonant frequency of the antenna, which in turn leads to the problem of reduced antenna performance in the extended state. Among them, Figure 7 The figure is a schematic diagram of the difference in S11 frequency when the antenna is in the extended state and the retracted state. Among them, S1,1 extended represents the curve diagram of the S11 frequency change when the electronic device is in the extended state; S1,1 closed represents the curve diagram of the S11 frequency change when the electronic device is in the retracted state.
[0027] See also Figure 3-4, is a structural schematic diagram of an electronic device provided by an embodiment of the present disclosure, the electronic device includes a first frame 100, a second frame 200 and a feed source 300, the first frame 100 can be extended or retracted relative to the second frame 200, so that the electronic device can be switched between an extended state and a retracted state; the first frame 100 includes a first conductive frame 110, the second frame 200 includes a second conductive frame 210, the first conductive frame 110 and the second conductive frame 210 are stacked, and the first conductive frame 110 is located on the outside of the second conductive frame 210, the second conductive frame 210 includes a first segment 211 and a second segment 212, a first break 220 is formed between the first segment 211 and the second segment 212, and the first conductive frame 110 is provided with a second break 120;
[0028] The feed source 300 is electrically connected to the first segment 211, and the feed source 300, the first conductive frame 110 and the second conductive frame 210 together form a target antenna;
[0029] When the electronic device is in the retracted state, the first break 220 is aligned with the second break 120; when the electronic device is in the extended state, at least a portion of the first break 220 is opposite to the first conductive frame 110;
[0030] The first resonant frequency is smaller than the second resonant frequency, the first resonant frequency is the resonant frequency of the target antenna when the electronic device is in a retracted state, and the second resonant frequency is the resonant frequency of the target antenna when the electronic device is in an extended state.
[0031] The electronic device may be any type of retractable screen electronic device. For example, in the embodiment of the present disclosure, the electronic device is a scroll screen electronic device. Figure 3-4 The electronic device may include two stacked screens, wherein the first frame 100 and the second frame 200 are frames of two screens. Thus, when the first frame 100 extends relative to the second frame 200, the display area of the electronic device increases, and correspondingly, when the first frame 100 retracts relative to the second frame 200, the display area of the electronic device decreases.
[0032] From the above discussion, it can be seen that when the electronic device is in the unfolded state, the resonant frequency of the target antenna will be higher due to the reduction of the antenna radius, that is, the first resonant frequency is lower than the second resonant frequency. Based on this, please refer to Figure 3-4In one embodiment of the present disclosure, at least a portion of the first break 220 is opposite to the first conductive frame 110, which means that the end of the first conductive frame 110 extends toward the first break 220 relative to the second segment 212 and extends to a position opposite to the first break 220. At this time, the first segment 211 is coupled with the second segment 212 on the one hand, and the antenna signal coupled to the second segment 212 can be transmitted to the first conductive frame 110. On the other hand, the first segment 211 can also be coupled with the first conductive frame 110, so relative to Figure 2 As shown in the state, the antenna signal fed into the first segment 211 can be more strongly coupled to the first frame 100, so that the resonant frequency of the target antenna is appropriately shifted toward the low frequency direction, which is helpful to alleviate the problem of high resonant frequency of the target antenna when it is in the unfolded state, thereby helping to improve the antenna performance of the target antenna. Figure 8 Schematic diagram of the S11 frequency difference when the antenna is in the extended state and the retracted state in this embodiment.
[0033] Also, see Figure 5-6 In another embodiment of the present disclosure, at least a portion of the first break 220 is opposite to the first conductive frame 110, which may also mean that the first conductive frame 110 may also cross the first break 220, so that the first break 220 is opposite to the first conductive frame 110. Figure 4 For the embodiment of the present invention, the distance between the first conductive frame 110 and the first segment 211 is closer, and the facing area is larger, so that the antenna signal fed into the first segment 211 can be more strongly coupled to the first frame 100, so that the resonant frequency of the target antenna is appropriately shifted to the low frequency direction, which is conducive to alleviating the problem of the high resonant frequency of the target antenna when it is in the unfolded state, thereby helping to improve the antenna performance of the target antenna. Fig. 9 , is a schematic diagram of the S11 frequency difference when the antenna is in the extended state and the retracted state in this implementation. Fig. 9 It can be seen that from the S11 curve of the antenna in this embodiment, it can be clearly observed that the resonant frequency of the antenna changes much less in the closed and unfolded states. At this time, combined with other conventional antenna technologies, it is easy to take into account both the unfolded and closed states at the same time.
[0034] Moreover, the bandwidth in the unfolded state is wider because the extended portion of the first frame 100 (ie, the fifth segment 113 hereinafter) will generate additional resonance, thereby expanding the bandwidth of the antenna.
[0035] The above solutions are only described from the perspective of resonant frequency. In fact, they also have other advantages, such as Figure 6In the illustrated embodiment, when the electronic device is in the unfolded state, the physical length of the antenna becomes longer, the antenna radiation effect is better, the head and hand derating is smaller, the extended portion of the outer frame produces additional resonance, the antenna field energy is more dispersed, the specific absorption rate (SAR) is lower, and so on.
[0036] See also Figure 4 or Figure 6 When the electronic device is in the unfolded state, the antenna signal fed from the feed source 300 into the first segment 211 is radiated through the first break 220 on the one hand, and is coupled to the first conductive frame 110 through the first break 220 on the other hand, and is transmitted to the second break 120 for radiation. Figure 3 When the electronic device is in the retracted state, the antenna signal fed from the feed source 300 into the first segment 211 is radiated through the first break 220 and the second break 120 at the same time.
[0037] In this embodiment, when the electronic device is in the unfolded state, the resonant frequency of the target antenna will be higher due to the reduction of the antenna radius. By making at least a portion of the first break 220 opposite to the first conductive frame 110, the antenna signal fed into the first segment 211 can be more strongly coupled to the first frame 100, so that the resonant frequency of the target antenna is appropriately shifted toward the low-frequency direction, which is conducive to alleviating the problem of the high resonant frequency of the target antenna when it is in the unfolded state, and further helps to improve the antenna performance of the target antenna.
[0038] Optionally, when the first resonant frequency is less than the second resonant frequency and the electronic device is in the unfolded state, the positions of the first conductive frame 110 and the first segment 211 are relatively staggered, and the positive projection of the first end of the first conductive frame 110 on the second conductive frame 210 is located within the first break 220, and the first end is the end of the first conductive frame 110 close to the first segment 211.
[0039] See also Figure 4 The first conductive frame 110 extends from one side of the second segment 212 relative to the second frame 200. Since the first segment 211 can be coupled with the second segment 212 and the first conductive frame 110 at the same time, the antenna signal fed into the first segment 211 can be more strongly coupled to the first frame 100, so that the resonant frequency of the target antenna is appropriately shifted toward the low-frequency direction, which is conducive to alleviating the problem of the high resonant frequency of the target antenna when it is in the unfolded state, and further helps to improve the antenna performance of the target antenna.
[0040] Optionally, the first conductive frame 110 includes a third segment 111 and a fourth segment 112, the second break 120 is formed between the third segment 111 and the fourth segment 112, and the first end is an end of the third segment 111 away from the fourth segment 112;
[0041] When the electronic device is in the unfolded state, the third segment 111 and the second segment 212 are arranged opposite to each other, and the third segment 111 and the second segment 212 are electrically connected, or the third segment 111 and the second segment 212 are coupled.
[0042] See also Figure 4 , the third segment 111 and the second segment 212 are electrically connected, which means that the third segment 111 and the second segment 212 are attached to each other, so that the antenna signal coupled from the first segment 211 to the second segment 212 can be directly transmitted to the first conductive frame 110. Accordingly, the third segment 111 and the second segment 212 are coupled, that is, there is a small gap between the third segment 111 and the second segment 212, so that the antenna signal coupled from the first segment 211 to the second segment 212 can be coupled to the first conductive frame 110. This ensures that the antenna signal coupled to the second segment 212 can be transmitted to the first conductive frame 110.
[0043] Optionally, when the first resonant frequency is less than the second resonant frequency and the electronic device is in the unfolded state, the first conductive frame 110 extends from one side of the second segment 212 relative to the second frame body 200, and the positive projection of the first end of the first conductive frame 110 on the second conductive frame 210 is located in the first segment 211, the first end is the end of the first conductive frame 110 close to the first segment 211, and the second break 120 is relatively staggered from the second segment 212.
[0044] See also Figure 6 , relative to Figure 4 In the embodiment, the distance between the first conductive frame 110 and the first segment 211 is closer, and the facing area is also larger. Therefore, the antenna signal fed into the first segment 211 can be more strongly coupled to the first frame 100, so that the resonant frequency of the target antenna is appropriately shifted toward the low-frequency direction, which is conducive to alleviating the problem of the high resonant frequency of the target antenna when it is in the unfolded state, and further helps to improve the antenna performance of the target antenna.
[0045] In addition, relative to Figure 4 For the embodiment, Figure 4In the embodiment shown, the position of the first frame 100 is relatively sensitive. Figure 4 If there is a certain position deviation in the position shown, the antenna performance will be degraded. Figure 6 In the illustrated embodiment, since the first conductive frame 110 has an extension portion opposite to the first segment 211 , the influence of position offset on antenna performance can be reduced, thereby facilitating further improving the antenna performance of the electronic device in the unfolded state.
[0046] Optionally, the first conductive frame 110 includes a fifth segment 113, a sixth segment 114 and a seventh segment 115, the sixth segment 114 is located between the fifth segment 113 and the seventh segment 115, the first end is an end of the fifth segment 113 away from the sixth segment 114, and the second break 120 is formed between the sixth segment 114 and the seventh segment 115;
[0047] The fifth segment 113 is electrically connected to the first segment 211 , or coupled to the first segment 211 ; the fifth segment 113 is electrically connected to the second segment 212 , or coupled to the second segment 212 .
[0048] See also Figure 5-6 In another embodiment of the present disclosure, the fifth segment 113 spans the first break 220. Thus, when the fifth segment 113 is electrically connected to the first segment 211, it is equivalent to increasing the antenna length of the target antenna, which is beneficial for shifting the antenna resonant frequency toward the low frequency direction. When the fifth segment 113 is coupled to the first segment 211, the antenna signal fed into the first segment 211 can be directly coupled to the fifth segment 113, which is beneficial for making the antenna signal more strongly coupled to the first frame 100, thereby appropriately shifting the resonant frequency of the target antenna toward the low frequency direction.
[0049] Optionally, the fifth segment 113 is coupled to the sixth segment 114;
[0050] When the electronic device is in the unfolded state, one end of the fifth segment 113 away from the first segment 211 is aligned with one end of the second segment 212 away from the first segment 211 .
[0051] In this embodiment, by aligning the end of the fifth segment 113 away from the first segment 211 with the end of the second segment 212 away from the first segment 211, the sixth segment 114 can be coupled to the fifth segment 113 and the second segment 212 respectively, thereby ensuring that the antenna signal transmitted to the second segment 212 can be better coupled to the first frame 100.
[0052] Optionally, the width of the first break 220 and the width of the second break 120 are respectively between 0.8 mm and 1.5 mm.
[0053] In this embodiment, by making the width of the first break 220 and the width of the second break 120 respectively between 0.8 mm and 1.5 mm, the coupling effect of the antenna signal at the first break 220 and the second break 120 can be improved.
[0054] Optionally, the second frame 200 further includes a third frame 230, which is covered on the outside of the second conductive frame 210, and when the electronic device is in the retracted state, the third frame 230 and the first conductive frame 110 together form an outer frame of the electronic device.
[0055] See also Figure 5-6 In this embodiment, the third frame 230 is provided on the outer side of the second conductive frame 210. Thus, when the electronic device is in the retracted state, the third frame 230 and the first conductive frame 110 are combined to form the outer frame of the electronic device, which is conducive to improving the overall aesthetics of the electronic device.
[0056] Another electronic device provided by an embodiment of the present disclosure includes a first frame 100, a second frame 200 and a feed source 300, wherein the first frame 100 can be extended or retracted relative to the second frame 200, so that the electronic device can be switched between an extended state and a retracted state; the first frame 100 includes a first conductive frame 110, the second frame 200 includes a second conductive frame 210, the first conductive frame 110 and the second conductive frame 210 are stacked, and the first conductive frame 110 is located outside the second conductive frame 210, the second conductive frame 210 includes a first segment 211 and a second segment 212, a first break 220 is formed between the first segment 211 and the second segment 212, and the first conductive frame 110 is provided with a second break 120;
[0057] The feed source 300 is electrically connected to the first segment 211, and the feed source 300, the first conductive frame 110 and the second conductive frame 210 together form a target antenna;
[0058] When the electronic device is in the retracted state, the first break 220 is aligned with the second break 120; when the electronic device is in the extended state, the first conductive frame 110 extends from one side of the second segment 212 relative to the second frame 200, the orthographic projection of the first end of the first conductive frame 110 on the second conductive frame 210 is located in the second segment 212, and the orthographic projection of the first end on the second conductive frame 210 is located at a position other than the second end of the second segment 212, the first end is an end of the first conductive frame 110 close to the first segment 211, and the second end is an end of the second segment 212 facing the first segment;
[0059] The first resonant frequency is greater than the second resonant frequency, the first resonant frequency is: the resonant frequency of the target antenna when the electronic device is in the retracted state; the second resonant frequency is: the resonant frequency of the target antenna when the electronic device is in the extended state.
[0060] Specifically, in some cases, when the electronic device is in the unfolded state, the operating frequency of the antenna may also be lower than that in the retracted state, that is, the first resonant frequency is greater than the second resonant frequency. When the resonant frequency of the antenna is low, the performance of the antenna will also be reduced. Based on this, in the embodiment of the present disclosure, by making the orthographic projection of the first end of the first conductive frame 110 on the second conductive frame 210 located within the second segment 212, and the orthographic projection of the first end on the second conductive frame 210 located at other positions outside the second end of the second segment 212, the gap between the first segment 211 and the first conductive frame 110 can be increased, which is conducive to weakening the antenna signal coupled to the first frame 100, and then the resonant frequency of the target antenna can be appropriately shifted to the high frequency direction, which is conducive to alleviating the problem of low resonant frequency of the target antenna when it is in the unfolded state, so as to improve the antenna performance of the target antenna.
[0061] Optionally, when the electronic device is in the retracted state, the first break 220 is opposite to the first conductive frame 110, and the first segment 211 is electrically connected to the second segment 212 through the first conductive frame 110, or the first segment 211 is coupled to the second segment 212 through the first conductive frame 110; when the electronic device is in the extended state, the orthographic projection of the first end of the first conductive frame 110 on the second conductive frame 210 is located outside the first segment 211.
[0062] Specifically, when the electronic device is in the retracted state, since the first break 220 is opposite to the first conductive frame 110, and the first segment 211 is electrically connected to the second segment 212 through the first conductive frame 110, or the first segment 211 is coupled to the second segment 212 through the first conductive frame 110, therefore, in the retracted state, the antenna length of the target antenna is formed by splicing the first segment 211, the first conductive frame 110 and the second segment 212. In the unfolded state, the orthographic projection of the first end of the first conductive frame 110 on the second conductive frame 210 is located outside the first segment 211, that is, the first segment 211 and the first conductive frame 110 are staggered, so the antenna length at this time is only the length of the first segment 211. It can be seen that in the embodiment, the antenna length in the unfolded state is less than the antenna length in the retracted state, so that when the first resonant frequency is greater than the second resonant frequency, the antenna frequency of the target antenna is shifted to a high frequency when the electronic device is in the unfolded state, so as to improve the performance of the antenna in this state.
