Detailed Description
To make the objects, technical solutions and advantages of the embodiments of the present application clearer, the embodiments of the present application will be described in detail below with reference to the accompanying drawings. However, it will be appreciated by those of ordinary skill in the art that in the examples of the present application, numerous technical details are set forth in order to provide a better understanding of the present application. However, the technical solution claimed in the present application can be implemented without these technical details and various changes and modifications based on the following embodiments. The following embodiments are divided for convenience of description, and should not constitute any limitation to the specific implementation manner of the present application, and the embodiments may be mutually incorporated and referred to without contradiction.
In some embodiments, most of the antennas in the retractable terminal have fixed antenna radiators, and the antenna radiator forms remain unchanged, which results in a certain degree of failure to ensure that the retractable terminal has good antenna performance in different retractable forms during the process of being retracted. Therefore, an embodiment of the present application provides a middle frame assembly of a retractable terminal, including: the antenna comprises a telescopic middle frame and a fixed middle frame, wherein a frame at the edge of the telescopic middle frame is provided with an antenna radiator; when the telescopic middle frame is in a contraction state, the telescopic middle frame is hidden in the fixed middle frame; when the telescopic middle frame is in an extending state, the telescopic middle frame extends out of the fixed middle frame; in the telescopic process of the telescopic middle frame, the form of an antenna radiating body is dynamically variable, so that the telescopic terminal is guaranteed to have better antenna performance under different telescopic forms to a certain extent.
In other embodiments, the tuning range of the tuning amplitude of the tuning mode of the retractable terminal is relatively limited, and the antenna efficiency is relatively low. The inventor finds out through research that the reason for the problem is that: the antenna efficiency is determined by the radiation efficiency and the reflectivity of the antenna radiator. The radiation efficiency of the antenna radiator is determined by the form of the antenna radiator, and the radiation efficiency is not changed when the form of the antenna radiator is not changed. The antenna radiator with the unchanged shape generally has better radiation efficiency only for a certain specific frequency band, and if the antenna radiator is applied to other frequency bands, the radiation efficiency is lost. Although the impedance tuning can be performed by the tuner or the antenna tuning switch to reduce the loss caused by adapting to other frequency bands, the tuner or the antenna tuning switch can only perform tuning in a small range to reduce the loss, and the tuning in the small range causes the adjustment range of the tuning amplitude to be limited. It follows that in order to adjust the antenna efficiency, only the reflectivity can be adjusted, but the adjustment of the reflectivity is dependent on a tuner or antenna tuning switch, which has a limited tuning range, resulting in a lower antenna efficiency. Therefore, the embodiment of the application can ensure that the terminal has better antenna performance under different telescopic forms to a certain extent, can expand the adjustment range of tuning amplitude, and improves the antenna efficiency.
The state of the middle frame assembly in this embodiment includes a contracted state and an extended state, which may be embodied as the state of the retractable middle frame, for example, when the retractable middle frame is in the contracted state, the state of the middle frame assembly is the contracted state; when the telescopic middle frame is in the stretching state, the state of the middle frame assembly is the stretching state. In a specific implementation, the middle frame component may be any one of the following: the upper and lower telescopic middle frame assembly, the left and right telescopic middle frame assembly and the middle frame assembly which can be stretched up and down and also can be stretched left and right. Wherein, the middle frame subassembly of upper and lower telescopic can be understood as: the telescopic middle frame in the middle frame assembly can be vertically telescopic relative to the fixed middle frame. The left and right telescopic middle frame components can be understood as follows: the telescopic middle frame in the middle frame assembly can be stretched and retracted left and right relative to the fixed middle frame. The middle frame component which can be stretched up and down and can also be stretched left and right can be understood as follows: the telescopic middle frame in the middle frame assembly can be stretched out and drawn back from left to right or from top to bottom relative to the fixed middle frame. The middle frame component in this embodiment can be applied to a scalable terminal, such as: a retractable mobile phone, a retractable tablet computer, etc. The retractable terminal may be: a terminal that can be extended and retracted up and down, a terminal that can be extended and retracted left and right, and a terminal that can be extended and retracted both up and down and left and right are not particularly limited in this embodiment.
The center subassembly of this embodiment is applied to retractable terminal, and retractable terminal can stretch out and draw back from top to bottom (or about), can retractable terminal length (or width) size change according to flexible condition, and width (or length) size keeps unchangeable. The telescopic terminal can adopt the middle frame component in the embodiment of the application. The following describes implementation details of the middle frame component of the retractable terminal of this embodiment in detail, and the following description is only provided for facilitating understanding and is not necessary for implementing this embodiment.
In one embodiment, the front schematic view of the middle frame assembly of the retractable terminal in the retracted state can refer to fig. 1 (a), and the front schematic view of the middle frame assembly in the extended state can refer to fig. 1 (b). The center subassembly includes: telescopic middle frame 101 and fixed middle frame 102, the frame 103 of the edge of telescopic middle frame 101 has the antenna radiator. When the retractable middle frame 101 is in the retracted state, referring to fig. 1 (a), the retractable middle frame 101 is hidden in the fixed middle frame 102. It will be appreciated that the retractable middle frame 101 is hidden from view in the fixed middle frame 102, and thus is not actually visible in fig. 1 (a). When the retractable middle frame 101 is in the extended state, referring to fig. 1 (b), the retractable middle frame 101 extends out of the fixed middle frame 102. In the process of stretching and retracting the stretchable middle frame 101, the shape of the antenna radiator is dynamically changeable, for example, in the process of stretching and retracting the stretchable middle frame 101, the radiation area of the antenna radiator is dynamically changed, so that the radiation efficiency of the antenna radiator is changed. The extension and retraction of the retractable middle frame 101 can be controlled by software or other mechanical means. In the telescopic process of the telescopic middle frame 101 in the embodiment of the present application, the dynamic change of the form of the antenna radiator means: in the process of stretching and retracting the stretchable middle frame 101, the radiation efficiency of the antenna radiator changes.
The antenna radiator is a metal conductor. In one example, the frame 103 at the edge of the retractable middle frame 101 is a metal frame, and the antenna radiator is a metal frame. That is, if the frame 103 itself is a metal frame, the metal frame itself can be used as an antenna radiator, and the antenna radiator does not need to be specially manufactured, which is beneficial to simplifying the structure of the middle frame assembly. By the extension and contraction of the telescopic middle frame 101, the length of the antenna radiator can be changed, so that the resonant frequency of the antenna is changed. In another example, the frame 103 at the edge of the retractable middle frame 101 is not a metal frame, for example, a plastic frame, and an antenna radiator may be disposed on the frame 103, so that the frame 103 can have the antenna radiator.
In a specific implementation, the bezel 104 that fixes the edge of the middle frame 102 may also have an antenna radiator, so that there may be more locations on the middle frame assembly that can be used to implement the function of an antenna. Optionally, the frame of the retractable middle frame 101 and the frame of the fixed middle frame 102 may be both metal frames.
In one example, the scalable length of the antenna radiator is determined based on the desired operating frequency band of the antenna radiator, the larger the upper frequency limit in the operating frequency band, the smaller the scalable length of the antenna radiator. In a specific implementation, if a section of the metal frame itself is used as the antenna radiator, the retractable length of the metal frame itself may determine the retractable length of the antenna radiator. It can therefore be understood that: the telescopic length of the metal frame itself can be determined based on the required working frequency band of the antenna radiator, and the larger the upper limit frequency in the working frequency band is, the smaller the telescopic length of the metal frame is. So set up for the antenna radiator is when different length, demonstrate different forms in flexible, the required working frequency channel of matching current form that can be fine, is favorable to making the terminal all have good antenna performance under different states.
In one example, a schematic side view of the retractable terminal with the middle frame assembly in the retracted state can refer to fig. 2 (a), and a schematic side view of the retractable terminal with the middle frame assembly in the extended state can refer to fig. 2 (b). As can be seen from fig. 2 (a), the frame 103 of the retractable middle frame 101 is hidden from the frame 104 of the fixed middle frame 102, and as can be seen from fig. 2 (b), the frame 103 of the retractable middle frame 101 extends out of the frame 104 of the fixed middle frame 102. It should be noted that fig. 2 (a) and fig. 2 (b) are only schematic diagrams of the frame 103 being retractable with respect to the frame 104, which are provided for easy understanding, and in a specific implementation, the frame 103 may be retractable with respect to the frame 104 by other manners, which is not limited in this embodiment.
In this embodiment, in the process of stretching and retracting, the form of the antenna radiator is dynamically changeable, when the stretchable antenna radiator is in different forms, the stretchable antenna radiator can radiate at a frequency band required by the current form, and the different forms can meet the radiation requirements of different frequency bands. For the frequency band required by the current form, the radiation efficiency of the telescopic antenna radiator in the current form is higher, the radiation efficiency loss does not exist, the radiation efficiency can be effectively improved, and the antenna efficiency is effectively improved. In addition, in the process of dynamically changing the form of the telescopic antenna radiator, the radiation area changes, which can be regarded as a tuning mode.
In one embodiment, the fixed middle frame in the middle frame assembly comprises: the first fixed middle frame and the second fixed middle frame are in an electric connection disconnection state; when the telescopic middle frame is in a contraction state, the telescopic middle frame is hidden in the first fixed middle frame; when the telescopic middle frame is in an extending state, the telescopic middle frame is positioned between the first fixed middle frame and the second fixed middle frame. For example, referring to fig. 1 (a) and 1 (b), the fixing middle frame 102 includes: the first fixing middle frame 1021 and the second fixing middle frame 1022 are in a state where the first fixing middle frame 1021 and the second fixing middle frame 1022 are electrically disconnected, where the place where the electrical connection is disconnected can be regarded as an open end of a section of the antenna, the position where the electrical connection is disconnected between the first fixing middle frame 1021 and the second fixing middle frame 1022 can be filled with a filler, and the first fixing middle frame 1021 and the second fixing middle frame 1022 can form a whole in appearance through the filler. The filler may be a material such as plastic that can electrically disconnect the first fixing middle frame 1021 and the second fixing middle frame 1022, and may be formed through an in-film injection molding process. When the retractable middle frame 101 is in a retracted state, the retractable middle frame 101 is hidden in the first fixed middle frame 1021; when the retractable middle frame 101 is in the extended state, the retractable middle frame 101 is located between the first fixed middle frame 1021 and the second fixed middle frame 1022. At this time, since the stretchable middle frame 101 extends out of the first fixed middle frame 1021, the position where the first fixed middle frame 1021 and the second fixed middle frame 1022 are electrically disconnected becomes the position where the stretchable middle frame 101 and the second fixed middle frame 1022 are electrically disconnected. This embodiment facilitates that the retractable middle frame can be hidden in the first fixed middle frame or extended out of the first fixed middle frame during the process of retraction.
It can be understood that fig. 1 (a) and 1 (b) correspond to the retractable middle frame 101 which extends up and down relative to the fixed middle frame 102, and the frame 103 includes: a left side frame 1031 at the left edge of the retractable middle frame 101 and a right side frame 1032 at the right edge of the retractable middle frame 101, wherein the left side frame 1031 and the right side frame 1032 are symmetrically arranged. Left side frame 1031 and right side frame 1032 symmetry set up, and the scalable degree of left side frame 1031 and right side frame 1032 is unanimous promptly for scalable center is at flexible in-process, and left side frame and right side frame are also flexible along with it, and the left side frame and the right side frame of symmetry can shelter from the structure that probably exists in the scalable center, improve the aesthetic property of center subassembly.
In this embodiment, one end of the middle frame is fixed, and the other end of the middle frame can be extended or shortened relative to the fixed middle frame. Wherein, the one end of scalable metal center can be fixed with the one end of fixed center, for example, in fig. 1 (b), the one end of scalable metal center 101 is fixed with the one end of first fixed center 1021 to when realizing that scalable metal center is flexible, realize that antenna radiator stretches out and draws back from top to bottom, can effectively promote radiant efficiency, thereby effectively improve antenna efficiency. The middle frame assembly of the terminal according to the embodiment of the application can combine the antenna radiator with dynamically variable form in the middle frame assembly in the process of up-and-down expansion of the terminal, so that the terminal can be ensured to have better antenna performance in different expansion forms to a certain extent. In addition, in the process of dynamically changing the form of the antenna radiator which can be stretched up and down, the radiation area can be changed, and the antenna can be regarded as a tuning mode.
Optionally, when the frame of the retractable middle frame 101 and the frame of the fixed middle frame 102 are both metal frames, this embodiment is equivalent to that the metal frames on the left and right (upper and lower) sides are divided into two separate sections (the two sections may be the first fixed middle frame 1021 and the second fixed middle frame 1022) or more, and the two or more metal middle frames are disconnected and not electrically connected. One segment (the telescopic middle frame 101) can control the telescopic motion in a software mode or other mechanical modes; the metal frames of other segments are fixed in length.
In one embodiment, the scalable middle frame in the middle frame component comprises: first scalable center and the scalable center of second, antenna radiation body includes: the frame of the edge of the first telescopic middle frame is provided with a first antenna radiator, and the frame of the edge of the second telescopic middle frame is provided with a second antenna radiator; when the first telescopic middle frame and the second telescopic middle frame are in a contraction state, the first telescopic middle frame is hidden at a first preset position of the fixed middle frame, and the second telescopic middle frame is hidden at a second preset position of the fixed middle frame; when the first telescopic middle frame and the second telescopic middle frame are in an extending state, the first telescopic middle frame and the second telescopic middle frame respectively extend outwards along two ends of the fixed middle frame; the first telescopic middle frame can dynamically change the shape of the first antenna radiator in the telescopic process, and the second telescopic middle frame can dynamically change the shape of the second antenna radiator in the telescopic process. The first preset position and the second preset position can be set according to actual needs, and can be the same or different, and can also be partially overlapped.
For example, referring to fig. 3 (a) and 3 (b), the middle frame assembly includes: a first telescopic middle frame 201 and a second telescopic middle frame 202, a border 203 of the edge of the first telescopic middle frame 201 having a first antenna radiator, and a border 204 of the edge of the second telescopic middle frame 202 having a second antenna radiator. When the first and second retractable middle frames 201 and 202 are in the retracted state, referring to fig. 3 (a), the first retractable middle frame 201 is hidden in the first predetermined position of the fixed middle frame 205, and the second retractable middle frame 202 is hidden in the second predetermined position of the fixed middle frame 205, that is, in fig. 3 (a), the first and second retractable middle frames 201 and 202 are hidden and cannot be seen from the front. When the first and second telescopic middle frames 201 and 202 are in the extended state, as shown in fig. 3 (b), the first and second telescopic middle frames 201 and 202 respectively extend outwards along two ends of the fixed middle frame 205; during the expansion and contraction of the first retractable middle frame 201, the form of the first antenna radiator is dynamically changeable, and during the expansion and contraction of the second retractable middle frame 202, the form of the second antenna radiator is dynamically changeable. In this embodiment, the frame 203 and the frame 204 may be metal frames, and the frame 203 itself may serve as the first antenna radiator and the frame 204 itself may serve as the second antenna radiator.
The scalable length of the first antenna radiator may be determined based on a first working frequency band required by the first antenna radiator, and the larger the upper limit frequency in the first working frequency band is, the smaller the scalable length of the first antenna radiator is, and the smaller the upper limit frequency in the first working frequency band is, the larger the scalable length of the first antenna radiator is. The scalable length of the second antenna radiator may be determined based on a second operating frequency band required by the second antenna radiator, and the higher the upper limit frequency in the second operating frequency band is, the smaller the scalable length of the second antenna radiator is, and the lower the upper limit frequency in the second operating frequency band is, the larger the scalable length of the second antenna radiator is. In specific implementation, the telescopic length of the first antenna radiator and the telescopic length of the second antenna radiator can be the same or different, which is beneficial to meeting different requirements for working frequency bands in practical application.
In a specific implementation, the border 206 that fixes the edge of the middle frame 205 may also have an antenna radiator, so that there can be more locations on the middle frame assembly that can be used to implement the function of an antenna. Optionally, the frame 203, the frame 204, and the frame 206 may be all metal middle frames.
In one embodiment, the fixed middle frame comprises: the third fixed middle frame and the fifth fixed middle frame are respectively positioned at two ends of the fourth fixed middle frame, the third fixed middle frame and the fourth fixed middle frame are in an electrical connection disconnection state, and the fourth fixed middle frame and the fifth fixed middle frame are in an electrical connection disconnection state; when the first telescopic middle frame and the second telescopic middle frame are in a contraction state, the first telescopic middle frame is hidden at a first preset position of the fourth fixed middle frame, and the second telescopic middle frame is hidden at a second preset position of the fourth fixed middle frame; when the first and second telescopic middle frames are in an extending state, the first telescopic middle frame extends towards the direction close to the third fixed middle frame, and the second telescopic middle frame extends towards the direction close to the fifth fixed middle frame.
For example, referring to fig. 3 (a) and 3 (b), the fixing middle frame 205 includes: the third fixed middle frame 2051, the fourth fixed middle frame 2052, and the fifth fixed middle frame 2053, where the third fixed middle frame 2051 and the fifth fixed middle frame 2053 are respectively located at two ends of the fourth fixed middle frame 2052, the third fixed middle frame 2051 and the fourth fixed middle frame 2052 are in a state of being electrically disconnected, and the fourth fixed middle frame 2052 and the fifth fixed middle frame 2053 are in a state of being electrically disconnected. The third fixing middle frame 2051 and the fourth fixing middle frame 2052 at the position where the electrical connection is disconnected may be filled with a filler. The fourth fixing middle frame 2052 may be filled with a filler at a position where the electrical connection is disconnected from the fifth fixing middle frame 2053. The third, fourth and fifth fixed middle frames 2051, 2052, 2053 may be integrated in appearance by the filler. The filler may be a material such as plastic that can achieve electrical disconnection, and the filler may be formed through an in-film injection molding process.
