Referring to fig. 1, 2 and 3, a mobile terminal 10 according to an embodiment of the present invention includes a bottom cover, a middle frame 11, a display screen 12 and an antenna assembly 13. The display screen 12 is carried on the side of the middle frame 11 facing the user, and the bottom cover is connected to the middle frame 11, and most of the bottom cover is located on the side of the middle frame 11 facing away from the user. For example, the bottom cover may include a cover plate portion and a side frame portion, the side frame portion is connected to a periphery of the cover plate portion and disposed around the cover plate portion, the cover plate portion is located on a side of the middle frame 11 facing away from the user, and the side frame portion may play a certain role in covering the middle frame 11.
First embodiment
Referring to fig. 1, 2 and 3, the antenna assembly 13 is located inside the mobile terminal 10 and includes a main board 100, a metal sheet 200 and a connecting member 300, the metal sheet 200 may be connected with the middle frame 11 and disposed on the middle frame 11, and of course, the metal sheet 200 may also be connected with a bottom cover and disposed on the bottom cover.
The main board 100 is disposed at an interval from the display screen 12 in the thickness direction of the mobile terminal 10, and the main board 100 is closer to the cover portion with respect to the display screen 12. In other words, the main board 100 and the display screen 12 are stacked on each other. The metal sheet 200 includes a free end arm 210 and a fixed end arm 220, both of which arms 210 and 220 may be of generally rectangular, plate-like configuration. The entire metal sheet 200 may be made of a copper material. The free end arm 210 and the fixed end arm 220 are connected in a bent manner, for example, the free end arm 210 and the fixed end arm 220 may be connected vertically, or they may be connected at an acute angle. The fixed end arm 220 is fixed on the middle frame 11, for example, the fixed end arm 220 can be prevented from being fixed in the middle frame 11 by ultrasonic welding or soldering, so that the connection strength between the whole metal sheet 200 and the middle frame 11 can be ensured, the fixed metal sheet 200 is prevented from shaking, and the stability and reliability of the middle connection between the metal sheet 200 and the middle frame 11 are improved. Of course, the fixed end arm 220 may be glued to prevent the fixing to the middle frame 11.
The free end arm 210 is spaced apart from the display screen 12 along the thickness direction of the mobile terminal 10, that is, the free end arm 210 and the display screen 12 are stacked on each other. The free end arm 210 is spaced apart from the main board 100 along the width direction of the mobile terminal 10, so that a certain gap exists between the free end arm 210 and the main board 100, and therefore, the orthographic projection of the free end arm 210 on the display screen 12 is located outside the orthographic projection of the main board 100 on the display screen 12. For example, the free end arm 210 has an orthographic projection on the display screen 12, the orthographic projection is referred to as a first orthographic projection, the main board 100 has an orthographic projection on the display screen 12, the orthographic projection is referred to as a second orthographic projection, and the first orthographic projection and the second orthographic projection keep a set distance from each other.
The thickness H of the free end arm 210 may range from 0.02mm to 0.2mm, and further, the thickness H of the free end arm 210 may also range from 0.05mm to 0.15 mm. For example, the thickness H of the free end arm 210 may be 0.05mm, 1mm, or 0.15 mm. Of course, the thickness H of the free end arm 210 may be made smaller in order to increase the distance between the free end arm 210 and the display screen 12 in the thickness direction of the mobile terminal 10, on the basis of ensuring the structural strength to prevent shaking. Of course, the thickness of the fixed end arm 220 may also range from 0.02mm to 0.2mm, for example, the thickness of the fixed end arm 220 and the thickness of the free end arm 210 may both be equal. The length or width a of the free end arm 210 may range from 1mm to 2mm, for example, the length or width a of the free end arm 210 is specifically 1mm, 1.5mm, or 2mm, and the like, and of course, on the basis of ensuring the structural strength to prevent shaking, the length or width a of the free end arm 210 may be made smaller to reduce the area of the orthographic projection of the free end arm 210 on the display screen 12 as much as possible. The fixed end arm 220 is further away from the display screen 12 than the free end arm 210. in colloquial, the fixed end arm 220 is located above the free end arm 210.
The connecting member 300 is connected between the main plate 100 and the free end arm 210, and the connecting member 300 may be connected to both the main plate 100 and the free end arm 210 by soldering. The connector 300 includes a first lug 310, a second lug 320, and a body portion 330, the body portion 330 having a width greater than both the first lug 310 and the second lug 320. The first lug 310 and the second lug 320 may have the same shape and are both elastic sheet-shaped structures, the first lug 310 and the second lug 320 are both located on the same side of the main body portion 330, the first lug 310 is connected with one end of the main body portion 330, and the second lug 320 is connected with the other end of the main body portion 330. Of course, the body portion 330, the first lug 310 and the second lug 320 may be integrally formed, for example, by injection, die casting or CNC process machining.
The main board 100 has a first supporting surface 110 and a first surface 120, the first surface 120 and the first supporting surface 110 are oppositely oriented, the first surface 120 is disposed facing the display screen 12, and the first supporting surface 110 is disposed opposite to the display screen 12. The free end arm 210 has a second support surface 211 and a second surface 212, the second surface 212 and the second support surface 211 being oriented oppositely, the second surface 212 being disposed facing the display screen 12, the second support surface 211 being disposed facing away from the display screen 12. Both the first 110 and second 211 support surfaces may be flush with each other, in colloquial terms, at the same height. The first lug 310 may be welded to the first support surface 110 and the second lug 320 may be welded to the second support surface 211. After the connector 300 is installed, the main body 330 is located above the first and second lugs 310 and 320, such that the main body 330 is further away from the display screen 12 than the first and second lugs 310 and 320. Therefore, the connecting member 300 is not located on the side of the main board 100 and the free end arm 210 facing the display screen 12, but on the side of the main board 100 and the free end arm 210 facing away from the display screen 12, so that the whole connecting member 300 can be spaced apart from the display screen 12 in the thickness direction of the mobile terminal 10. The spacing between the first surface 120 and the display screen 12 is smaller than the spacing between the second surface 212 and the display screen 12, in other words, the second surface 212 is farther away from the display screen 12 than the first surface 120.
In view of the fact that the larger display screen 12 has an orthographic projection in the thickness direction of the mobile terminal 10, the orthographic projection will cover the whole main board 100 and part of the free end arm 210, resulting in a coupling capacitance between the metal member on the display screen 12 and the free end arm 210 made of metal, and when the coupling capacitance is larger, the current input from the main board 100 to the free end arm 210 is cancelled by the coupling capacitance to generate a loss, thereby reducing the current entering the free end arm 210 and affecting the signal transmission performance of the whole metal sheet 200. In fact, the metal part on the display screen 12 and the free end arm 210 can be abstracted and equivalent to a plate capacitor structure, and when the overlapping area (i.e. the facing area) between the metal part on the display screen 12 and the free end arm 210 is increased, the capacitance of the plate capacitor structure is increased, i.e. the coupling capacitance between the display screen 12 and the free end arm 210 is increased. As the spacing between the metal on the display screen 12 and the free end arm 210 increases, the capacitance of the plate capacitor structure decreases, i.e., the coupling capacitance between the display screen 12 and the free end arm 210 decreases. The coupling capacitance between the display screen 12 and the free end arm 210 is proportional to the overlap area and inversely proportional to the distance between the two. The projection of the metal member on the display screen 12 in the certain terminal thickness direction is denoted as a first projection, the projection of the free end arm 210 in the certain terminal thickness direction is denoted as a second projection, and the area of the overlapping portion of the first projection and the second projection is equivalent to the overlapping area (i.e., the facing area).
If there is a portion of the free end arm 210 coinciding with the orthographic projection of the main board 100 on the display screen 12, a portion of the free end arm 210 will be located between the main board 100 and the display screen 12, i.e. a portion of the free end arm 210 is located below the main board 100 and above the display screen 12. Therefore, the overlapping area between the display screen 12 and the free end arm 210 is increased, and the distance between the display screen 12 and the free end arm 210 is reduced, so that the coupling capacitance between the metal member on the display screen 12 and the free end arm 210 is increased, so that the current input to the free end arm 210 by the main board 100 is offset by the larger coupling capacitance, and finally the current entering the free end arm 210 is reduced and the signal transmission performance of the whole metal sheet 200 is affected.
With the antenna assembly 13 in the above embodiment, since the orthographic projection of the free end arm 210 on the display screen 12 is located outside the orthographic projection of the main board 100 on the display screen 12, the free end arm 210 can be prevented from being located below the main board 100, and the main board 100 is prevented from being located at a height greater than the height of the free end arm 210, so that the free end arm 210 is located on the right side of the main board 100, and the free end arm 210 is located at approximately the same height as the main board 100. Therefore, on one hand, the overlapping area between the display screen 12 and the free end arm 210 can be reduced, on the other hand, the distance between the display screen 12 and the free end arm 210 can be increased, and finally, the coupling capacitance between the metal piece on the display screen 12 and the free end arm 210 is reduced, so that the current input to the free end arm 210 by the main board 100 is offset by the smaller coupling capacitance, and finally, the current entering the free end arm 210 is greatly increased, and the signal transmission performance of the whole metal sheet 200 is improved.
Of course, since the connecting member 300 is also supported by a metal material, the metal members on the connecting member 300 and the display screen 12 and the free end arm 210 can be abstracted and equivalent to a plate capacitor structure, and when a current on the main board 100 is input to the free end arm 210 through the connecting member 300, the coupling capacitance between the connecting member 300 and the display screen 12 can generate a cancellation effect on the current. Since the connecting member 300 is connected to the first supporting surface 110 and the second supporting surface 211 respectively, so that the connecting member 300 is located on both the main board 100 and the free end arm 210, the distance between the connecting member 300 and the display screen 12 can be increased, thereby reducing the coupling capacitance between the connecting member 300 and the metal members on the display screen 12, and further ensuring that the metal sheet 200 has sufficient current to improve the signal transmission performance.
Considering that the thickness H of the free end arm 210 ranges from 0.05mm to 0.15mm, the thickness of the free end arm 210 can be greatly reduced, so as to increase the distance between the free end arm 210 and the display screen 12, and reduce the coupling capacitance between the connecting member 300 and the metal member on the display screen 12. Meanwhile, the second surface 212 is farther away from the display screen 12 than the first surface 120, so as to prevent the first surface 120 and the second surface 212 from being flush with each other, and to increase the distance between the free end arm 210 and the display screen 12 to a certain extent, so as to reduce the above-mentioned coupling capacitance. Moreover, the length or width a of the free end arm 210 ranges from 1mm to 2mm, so that the length and width of the free end arm 210 can be greatly reduced, thereby reducing the overlapping area between the free end arm 210 and the metal member on the display screen 12, and also reducing the coupling capacitance. Therefore, by reducing the amount of current offset by the coupling capacitor, it is possible to ensure sufficient current on the metal plate 200 to improve the signal transmission performance.
For a conventional metal sheet 200, the width is typically 3mm and the thickness is typically 1.5 mm. When the width of the free end arm 210 in the above embodiment is 1.5mm and the thickness of the free end arm 210 is 0.1mm, the width of the free end arm is reduced by 50% compared to the conventional metal sheet 200, and the thickness of the free end arm is reduced by 90% compared to the conventional metal sheet 200. The conventional metal sheet 200 and the metal sheet 200 in the above-described embodiment may be subjected to simulation analysis. Referring to fig. 4, for example, the S11 parameter of both the conventional metal sheet 200 and the metal sheet 200 of the above embodiment can be tested, and it can be seen that both the metal sheets 200 are more sensitive to high frequency, the high frequency S11 is somewhat offset, but the bandwidths of the two are substantially closer. For another example, the radiation efficiency of both the conventional metal sheet 200 and the metal sheet 200 of the above embodiment can be tested, referring to fig. 5, when both are tested for the gps l1 signal, the frequency of the gps l1 signal is 1575.42 ± 1.023MHz, and it can be seen that the transmission efficiency of the metal sheet 200 in the above embodiment is about 1dB higher than that of the conventional metal sheet 200. Referring to fig. 6, when both of the n79 signals are tested for the n79 signal, the frequency of the n79 signal is 4.4G to 5.0G, and it can be seen that the transmission efficiency of the metal sheet 200 in the above embodiment is about 0.5dB higher than that of the conventional metal sheet 200, therefore, the transmission performance of the antenna assembly 13 in the above embodiment is obviously better than that of the conventional antenna assembly 13 through the simulation experiment.
Second embodiment
Referring to fig. 7, the antenna assembly 13 of the second embodiment differs from the antenna assembly 13 of the first embodiment mainly in the positional relationship between the free end arm 210 and the fixed end arm 220.
The antenna assembly 13 is located inside the mobile terminal 10 and includes a main board 100, a metal sheet 200 and a connecting member 300, the metal sheet 200 may be connected with the middle frame 11 and disposed on the middle frame 11, and of course, the metal sheet 200 may also be connected with a bottom cover and disposed on the bottom cover.
The main board 100 is disposed at an interval from the display screen 12 in the thickness direction of the mobile terminal 10, and the main board 100 is closer to the cover portion with respect to the display screen 12. In other words, the main board 100 and the display screen 12 are stacked on each other. The metal sheet 200 includes a free end arm 210 and a fixed end arm 220, both of which arms 210 and 220 may be of generally rectangular, plate-like configuration. The entire metal sheet 200 may be made of a copper material. The free end arm 210 and the fixed end arm 220 are connected in a bent manner, for example, the free end arm 210 and the fixed end arm 220 may be connected vertically, or they may be connected at an acute angle. The fixed end arm 220 is fixed on the middle frame 11, for example, the fixed end arm 220 can be prevented from being fixed in the middle frame 11 by ultrasonic welding or soldering, so that the connection strength between the whole metal sheet 200 and the middle frame 11 can be ensured, the fixed metal sheet 200 is prevented from shaking, and the stability and reliability of the middle connection between the metal sheet 200 and the middle frame 11 are improved. Of course, the fixed end arm 220 may be glued to prevent the fixing to the middle frame 11.
The free end arm 210 is spaced apart from the display screen 12 along the thickness direction of the mobile terminal 10, that is, the free end arm 210 and the display screen 12 are stacked on each other. The free end arm 210 is spaced apart from the main board 100 along the width direction of the mobile terminal 10, so that a certain gap exists between the free end arm 210 and the main board 100, and therefore, the orthographic projection of the free end arm 210 on the display screen 12 is located outside the orthographic projection of the main board 100 on the display screen 12. For example, the free end arm 210 has an orthographic projection on the display screen 12, the orthographic projection is a first orthographic projection, the main board 100 has an orthographic projection on the display screen 12, the orthographic projection is a second orthographic projection, and the first orthographic projection and the second orthographic projection keep a set distance from each other.
The thickness of the free end arm 210 may range from 0.02mm to 0.2mm, and further, the thickness of the free end arm 210 may also range from 0.05mm to 0.15 mm. For example, the thickness of the free end arm 210 may be 0.05mm, 1mm, or 0.15 mm. Of course, on the basis of ensuring the structural strength to prevent shaking, the thickness of the free end arm 210 may be made smaller so as to increase the distance between the free end arm 210 and the display screen 12 in the thickness direction of the mobile terminal 10. Of course, the thickness of the fixed end arm 220 may also range from 0.02mm to 0.2mm, for example, the thickness of the free end arm 210 may be less than or equal to the thickness of the fixed end arm 220. The length or width of the free end arm 210 may range from 1mm to 2mm, for example, the length or width of the free end arm 210 is specifically 1mm, 1.5mm, or 2mm, and the like, and of course, on the basis of ensuring the structural strength to prevent shaking, the length or width of the free end arm 210 may be made smaller, so as to reduce the area of the orthographic projection of the free end arm 210 on the display screen 12 as much as possible. The fixed end arm 220 is closer to the display screen 12 than the free end arm 210, and in colloquial terms, the fixed end arm 220 is located below the free end arm 210.
The connecting member 300 is connected between the main plate 100 and the free end arm 210, and the connecting member 300 may be connected to both the main plate 100 and the free end arm 210 by soldering. The connector 300 includes a body portion 330, a first lug 310, and a second lug 320, the body portion 330 having a width greater than both the first lug 310 and the second lug 320. The first lug 310 and the second lug 320 may have the same shape and are both elastic sheet-shaped structures, the first lug 310 and the second lug 320 are both located on the same side of the main body portion 330, the first lug 310 is connected with one end of the main body portion 330, and the second lug 320 is connected with the other end of the main body portion 330. Of course, the body portion 330, the first lug 310 and the second lug 320 may be integrally formed, for example, by injection, die casting or CNC process machining.
The main board 100 has a first surface 120 and a first supporting surface 110, the first surface 120 and the first supporting surface 110 are oppositely oriented, the first surface 120 is disposed facing the display screen 12, and the first supporting surface 110 is disposed opposite to the display screen 12. The free end arm 210 has a second surface 212 and a second support surface 211, the second surface 212 and the second support surface 211 being oriented oppositely, the second surface 212 being disposed facing the display screen 12 and the second support surface 211 being disposed facing away from the display screen 12. Both the first 110 and second 211 support surfaces may be flush with each other, in colloquial terms, at the same height. The first lug 310 may be welded to the first support surface 110 and the second lug 320 may be welded to the second support surface 211. After the connector 300 is installed, the main body 330 is located above the first and second lugs 310 and 320, such that the main body 330 is further away from the display screen 12 than the first and second lugs 310 and 320. Therefore, the connecting member 300 is not located on the side of the main board 100 and the free end arm 210 facing the display screen 12, but on the side of the main board 100 and the free end arm 210 facing away from the display screen 12, so that the whole connecting member 300 can be spaced apart from the display screen 12 in the thickness direction of the mobile terminal 10. The spacing between the first surface 120 and the display screen 12 is smaller than the spacing between the second surface 212 and the display screen 12, in other words, the second surface 212 is farther away from the display screen 12 than the first surface 120.
With reference to the description related to the first embodiment, the antenna assembly 13 in the second embodiment can also reduce the coupling capacitance between the free end arm 210 and the metal member on the display screen 12 by the above arrangement, so as to ensure that the metal sheet 200 has sufficient current to improve the signal transmission performance.
The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
