Detailed Description
The technical solution in the present application will be described below with reference to the accompanying drawings.
The scheme provided by the embodiment of the application can be applied to electronic equipment with a keyboard or a plurality of entity controls, such as a mobile phone, a tablet computer, a television (or a smart screen), a portable computer, a notebook computer, a two-in-one computer, a watch, a wireless keyboard, a tablet protective sleeve with a keyboard and the like. For convenience of understanding, the embodiment of the present application is described with reference to fig. 1, taking a notebook computer 100 as an example, and with reference to fig. 2, taking a two-in-one computer 200 as an example.
Fig. 1 shows a schematic structural diagram of an electronic device. The electronic device may be, for example, a notebook computer 100.
The notebook computer 100 may include a first housing 110, a second housing 120, a display screen 130, a keyboard 140, and a hinge 150. The display screen 130 may be fixed on the first housing 110. The keypad 140 may be fixed on the second housing 120. The hinge 150 may be hinged between the first casing 110 and the second casing 120, and the hinge 150 may enable the first casing 110 to rotate relative to the side of the second casing 120 (or the side of the second casing 120 relative to the first casing 110) to enable the notebook computer 100 to be folded and unfolded.
When the notebook computer 100 is folded, an included angle between the first casing 110 and the second casing 120 may tend to 0 °, the display screen 130 and the keyboard 140 may be close to each other, and the display screen 130 and the keyboard 140 may be accommodated in a cavity formed by the first casing 110 and the second casing 120.
When the notebook computer 100 is opened, the included angle between the first casing 110 and the second casing 120 tends to 90 ° to 180 °, and the display screen 130 and the keyboard 140 can be away from each other, so that the display screen 130 and the keyboard 140 can be exposed for a user to use.
Fig. 2 shows a schematic structural diagram of another electronic device. The electronic device may be a two-in-one computer 200, for example. The two-in-one computer 200 may include a tablet computer 210 and a tablet protective case 220.
Tablet computer 210 may include tablet housing 211, display screen 212. Specifically, the tablet housing 211 may include a bezel and a rear cover. The bezel surrounds the periphery of the display screen 212 and surrounds the periphery of the rear cover. The cavity formed by the bezel and the back cover may be used to house the display screen 212.
Tablet sleeve 220 may include tablet region 221, keyboard region 222. The tablet region 221 may be used to secure the tablet computer 210. The keyboard area 222 may be the area of the tablet case 220 that contains the keyboard 2221. The tablet area 221 and the keyboard area 222 can move relative to each other, so that the tablet computer 210 and the keyboard 2221 can be attached to each other or inclined relative to each other, and thus when the included angle between the tablet computer 210 and the keyboard 2221 is maintained at 90-180 °, a user can observe the display screen 20 and strike the keyboard 2221.
In one example, as shown in fig. 2, the tablet region 221 can include a back cover magnetic attraction region 2211. The back cover magnetic attraction area 2211 may magnetically attract at least a portion of the back cover of the tablet computer 210 so that the tablet computer 210 may be secured within the tablet area 221. Optionally, the tablet region 221 may further include a side magnetic attraction region 2212, where the side magnetic attraction region 2212 may magnetically attract one side of a frame of the tablet computer 210, and the side may be spaced apart from a region of the tablet computer 210 that is magnetically attracted by the back cover magnetic attraction region 2211.
In another example, the plate region 221 may include a side magnetically attracted region. The side magnetic attraction area may magnetically attract one side of the bezel of the tablet computer 210, so that the tablet computer 210 may be fixed in the tablet area 221.
In yet another example, the flat region 221 may include a flat carrying surface, a flat plate edge wrap. The flat plate edge wrapper may be disposed vertically with respect to the flat plate edge wrapper and may surround the periphery of the flat plate carrying surface, such that the flat plate edge wrapper and the flat plate carrying surface may form a slot for receiving the tablet computer 210. The bottom of the slot body may be a flat plate carrying surface, which may be attached to the back cover of the tablet computer 210. The side wall of the slot body may be a flat plate edge, which may be attached to the frame of the tablet computer 210.
In accordance with an example of an electronic device including a keyboard as shown in fig. 1-2, an exploded view of a keyboard 300 is set forth below in conjunction with fig. 3. It should be understood that the keyboard 300 shown in fig. 3 may be, for example, the keyboard 140 shown in fig. 1, and may also be, for example, the keyboard 2221 shown in fig. 2.
Keyboard 300 may include a plurality of keycaps 310, a keyboard frame 320, and a keyboard floor 330.
The keyboard frame 320 may be fixed on the keyboard floor 330, for example (the black dots in fig. 3 may be used to indicate solder that fixes the keyboard frame 320 on the keyboard floor 330), and the keyboard frame 320 is disposed in parallel with respect to the keyboard floor 330. The keyboard frame 320 may include a plurality of keyboard through holes 321, and the plurality of keyboard through holes 321 may correspond to the plurality of key caps 310 one to one. That is, any keycap 310 may pass through a corresponding keyboard through hole 321.
The key caps 310 are movable in the corresponding keyboard through holes 321 to realize a telescopic motion relative to the keyboard frame 320 and the keyboard base plate 330. As shown in fig. 4, the keypad 300 may further include a keypad spring 340. The keyboard spring 340 may pass through the keyboard through hole and be connected between the keycap and the keyboard base plate.
In one example, when keycap 310 is not depressed, keyboard spring 340 may be in a free state such that at least a portion of the keycap may be located outside of the keyboard through hole. When the user presses the key cap 310, the keyboard spring 340 may be in a pressed state, so that the key cap 310 may be retracted into the corresponding keyboard through hole 321 and abut on the keyboard base 330. When the user lifts the finger, the keyboard spring 340 can return to the free state, so that the key cap 310 can be separated from the keyboard base 330 and extend out of the corresponding keyboard through hole 321.
The electronic device may include an antenna to implement wireless communication functionality of the electronic device. The antenna may be disposed in a relatively concealed location of the electronic device to reduce the number of exposed components of the electronic device. For example, an antenna radiator of the antenna may be disposed near the rotation axis 150 as shown in fig. 1. As another example, the antenna radiator of the antenna may be disposed on the key cap 310, the keyboard frame 320, or the keyboard floor 330 shown in fig. 3.
With the development of communication technology, electronic devices need to support more and more communication functions, and therefore, the electronic devices need to have relatively more antennas. In a situation where the exposure of the device is minimized or avoided, the area near the rotating shaft 150 generally cannot accommodate a larger number of antenna radiators, and therefore, it is difficult for the electronic device to support more communication functions. A larger number of antenna radiators can be generally disposed in the keyboard area, however, when a user's finger presses the keyboard, the performance of the antenna radiator on the keyboard may be deteriorated, and the antenna of the electronic device may not work normally.
A keyboard 300 provided in an embodiment of the present application is described below with reference to fig. 5 to 12, where the keyboard 300 includes an antenna. The antenna may include a feeding unit, a feeding part 510, a first antenna radiator 521, and a second antenna radiator 522. In one example, the thickness of the feeding part 510 may be 0.5 mm. The feeding component 510 may be electrically connected to a circuit board on the electronic device 100 or the keyboard 300 via an electrical connector, and further transmit data to a feeding unit (e.g., a chip or a processor) on the circuit board. The electrical connections may be located, for example, within keyboard floor 330, keyboard frame 320, or between keyboard floor 330, keyboard frame 320.
Fig. 5 is a schematic structural diagram of a keyboard 300 according to an embodiment of the present application.
In one example, a power feeding part 510 may be disposed on the keypad chassis 330 or the keypad frame 320.
For example, referring to fig. 5 and 6, the keyboard 300 may include a first insulating member 611, and both the keyboard frame 320 and the keyboard substrate 330 may be made of conductive materials. The first insulating part 611 may be fixed on the keypad bottom plate 330, and the first insulating part 611 may be connected between the power feeding part 510 and the keypad bottom plate 330. Alternatively, the feeding part 510 may be fixed on the keypad chassis 330 by the first insulating part 611. The height of the first insulating member 611 may be 1mm, for example. That is, the distance between the feeding part 510 and the keypad chassis 330 may be 1 mm. The electrical connections may be encased by first insulating member 511, for example.
A first interval 511 is formed between the first end of the feeding part 510 and the keypad frame 320, and a second interval 512 is formed between the second end of the feeding part 510 and the keypad frame 320. That is, both ends of the feeding part 510 are not directly connected to the keypad frame 320.
Optionally, the keyboard 300 may further include a second insulating member located in the first space 511, and a third insulating member located in the second space 512. That is, the first end of the feeding part 510 is directly connected to the keypad frame 320 through the second insulating part, and the second end of the feeding part 510 is directly connected to the keypad frame 320 through the third insulating part.
The keypad frame 320 may be divided into a feeding part 510 and the remaining keypad frames except the feeding part 510. The remaining keyboard frame comprises a second insulating part, a third insulating part and a keyboard frame body, and the keyboard frame body can be made of conductive materials. The second insulating member is connected between the first end of the feeding member 510 and the keyboard frame body, and the third insulating member is connected between the second end of the feeding member 510 and the keyboard frame body.
As another example, in conjunction with fig. 5 and 7, the power feeding unit 510 may be disposed on the keyboard substrate 330. In the case that the keypad frame 320 is made of a conductive material, a first interval 511 is formed between the first end of the feeding part 510 and the keypad frame 320, and a second interval 512 is formed between the second end of the feeding part 510 and the keypad frame 320. That is, both ends of the feeding part 510 are not directly connected to the keypad frame 320. The keypad chassis 330 may further include a fourth insulating member 614, and the fourth insulating member 614 may surround the feeding member 510 to cut off a signal from the feeding member 510 from being transmitted from an inner side of the fourth insulating member 614 to an outer side of the fourth insulating member 614, wherein the inner side of the fourth insulating member 614 is relatively closer to the feeding member 510 and the outer side of the fourth insulating member 614 is relatively farther from the feeding member 510. The electrical connections may be, for example, enclosed by a portion of keyboard tray 330, and the portion of keyboard tray 330 may be located within fourth insulating member 614.
For another example, in combination with fig. 5 and 8, the keyboard frame 320 is made of an insulating material, and the power feeding unit 510 may be fixed on the keyboard frame 320, such as a side of the keyboard frame 320 close to the keyboard base 330 (as shown in fig. 7), a side of the keyboard frame 320 far from the keyboard base 330, or an intermediate layer of the keyboard frame 320. The spacing between feed block 510 and keypad backplane 330 may be, for example, 1 mm. The electrical connections may be wrapped by keyboard frame 320, for example.
In one example, keyboard frame 320 may include a power feed component 510.
For example, in conjunction with fig. 5 and 9, the keyboard frame 320 may include a first frame layer 910 and a second frame layer 920, and the second frame layer 920 may be located between the keyboard floor 330 and the first frame layer 910. The first frame layer 910 may use a conductive material, and the second frame layer 920 may use an insulating material. By removing a part of the material of the first frame layer 910, the feeding part 510 and the remaining first frame layer 911 may be obtained, wherein the feeding part 510 and the remaining first frame layer 911 are both arranged on the second frame layer 920. The thickness of the first frame layer 910 may be, for example, 0.5mm, and the thickness of the second frame layer 920 may be, for example, 1 mm. That is, the distance between the feeding part 510 and the keypad chassis 330 may be 1 mm. The electrical connector may be wrapped by the second frame layer 920, for example.
A first gap 511 is formed between the first end of the feeding member 510 and the remaining first frame layer 911, and a second gap 512 is formed between the second end of the feeding member 510 and the remaining first frame layer 911. That is, both ends of the feeding part 510 are not directly connected to the remaining first frame layer 911.
Optionally, the keyboard frame 320 may further include a second insulating part and a third insulating part, the second insulating part being located in the first space 511, and the third insulating part being located in the second space 512. That is, the first end of the feeding part 510 is directly connected to the remaining first frame layer 911 through the second insulating part, and the second end of the feeding part 510 is directly connected to the remaining first frame layer 911 through the third insulating part.
The keyboard frame 320 may include a first keyboard through hole 321, a second keyboard through hole 322. The keyboard 300 may include a first key cap 311, a second key cap 312, a first spring 341, a second spring 342. The first key cap 311 may correspond to the first keyboard through hole 321, and the first spring 341 may be connected between the keyboard base 330 and the first key cap 311. The second key cap 312 may correspond to the second keyboard through hole 322, and the second spring 342 may be coupled between the keyboard base 330 and the second key cap 312.
The first key cap 311 may be provided with a first antenna radiator 521 of an antenna, and the second key cap 312 may be provided with a second antenna radiator 522 of the antenna. As shown in fig. 6 to 9, the first antenna radiator 521 may be accommodated in a cavity formed by the first key cap 311 and the first keyboard through hole 321, and the second antenna radiator 522 may be accommodated in a cavity formed by the second key cap 312 and the second keyboard through hole 322. In other examples, the antenna radiator may be located inside the material of the keycap, i.e. in the middle of the keycap; alternatively, the antenna radiator may be located on a side of the keycap remote from the keyboard substrate 330.
The distance between the first keyboard through hole 321 and the feeding part 510 and the distance between the second keyboard through hole 322 and the feeding part 510 are all smaller than a preset threshold (for example, the width of the feeding part 510). It follows that the distance separating the feeding member 510 from the first antenna radiator 521 may be relatively small, and the distance separating the feeding member 510 from the second antenna radiator 522 may be relatively small. Accordingly, the feeding means 510 may couple feeds for the first antenna radiator 521, and the feeding means 510 may couple feeds for the second antenna radiator 522. The position of the feeding part 510 connected to the feeding source may be, for example, the middle part of the feeding part 510.
In one example, as shown in fig. 5, the first keypad through hole 321 and the second keypad through hole 322 may be respectively located at both sides of the feeding part 510, and the first keypad through hole 321 may be adjacent to the second keypad through hole 322.
In another example, the first keypad via 321 and the second keypad via 322 may be two keypad vias on a first row, and the feeding member 510 may be located between the first row and a second row, wherein the first row and the second row may be two adjacent rows of the keypad frame 320.
In yet another example, the first keypad via 321 and the second keypad via 322 may be two keypad vias on a first column, and the feeding part 510 may be located between the first column and a second column, wherein the first column and the second column may be two adjacent columns of the keypad frame 320.
In yet another example, the first and second keyboard vias 321, 322 may be located on a first and second row of the keyboard frame 320, respectively, which may be two adjacent rows of the keyboard frame 320.
In yet another example, the first and second keyboard vias 321, 322 may be located in a first and second column of the keyboard frame 320, respectively, and the first and second columns may be two adjacent columns of the keyboard frame 320.
Fig. 6 to 9 show various arrangements of the feeding section 510 on the keypad 300. With respect to the portion circled by the dashed line in fig. 5, and with reference to fig. 10 to 12, various arrangements of the antenna radiator of the antenna on the keyboard 300 will be described.
Fig. 10 is a combination structure of a first antenna radiator 521 and a second antenna radiator 522 according to an embodiment of the present application.
The first antenna radiator 521 may have a ring-shaped structure, and the first antenna radiator 521 may have, for example, a circular ring shape, a triangular frame shape, a square frame shape, a polygonal frame shape, or the like. The width of the inner loop of the first antenna radiator 521 may be 13.3mm, for example. The first antenna radiator 521 may be used to implement the function of a loop antenna. The feeding unit 510 may feed the first antenna radiator 521 on a side close to the feeding unit 510. That is, the minimum distance between the feeding part 510 and the first antenna radiator 521 may be smaller than the preset coupling distance. The antenna radiator with the annular structure can form a wave-shaping current element, and is beneficial to realizing a relatively high frequency band.
The line width of the ring structure may be, for example, 1 mm. In addition, the line width of the annular structure is increased, so that the resonant frequency of the antenna radiator is improved; accordingly, reducing the line width of the loop structure is advantageous for reducing the resonant frequency of the antenna radiator.
Similarly, the second antenna radiator 522 may have a ring structure, and the second antenna radiator 522 may have, for example, a circular ring shape, a triangular frame shape, a square frame shape, a polygonal frame shape, and the like, and the specific shape of the ring structure may not be limited in the present application. So that the second antenna radiator 522 can be used to implement the function of a loop antenna. The feeding means 510 may feed a side of the second antenna radiator 522 close to the feeding means 510. That is, the minimum distance between the feeding part 510 and the second antenna radiator 522 may be less than the preset coupling distance.
In order to make the antenna have a relatively wide bandwidth, the resonant frequencies of the first and second antenna radiators 521, 522 are different, and thus the structures of the first and second antenna radiators 521, 522 may be different. For example, the first and second antenna radiators 521 and 522 may have different line widths.
Fig. 11 is another combination structure of the first antenna radiator 521 and the second antenna radiator 522 according to the embodiment of the present application. The second antenna radiator 522 may have a ring structure.
Unlike the combination structure shown in fig. 11, the first antenna radiator 521 may include a first notch 5213, and the first end 5211 of the first antenna radiator 521 and the second end 5212 of the first antenna radiator 521 are respectively located at two sides of the first notch 5213. The feeding unit 510 may feed power to a side of the first antenna radiator 521 away from the first notch 5213. That is, a distance between a side of the first antenna radiator 521 away from the first notch 5213 and the feeding block 510 may be smaller than a predetermined coupling distance.
The gap allows the first antenna radiator 521 to form a half-wave current element, and the resonant frequency of the first antenna radiator 521 is lower than the resonant frequency of the second antenna radiator 522 under the condition that the parameters of the width, the length, the line width and the like of the antenna radiators are the same.
Fig. 12 is a further combination structure of the first antenna radiator 521 and the second antenna radiator 522 according to the embodiment of the present application. The first antenna radiator 521 may include a first notch 5213.
Unlike the combined structure shown in fig. 12, the second antenna radiator 522 may include a second notch 5223, where the two sides of the second notch 5223 are the first end 5221 of the second antenna radiator 522 and the second end 5222 of the second antenna radiator 522, respectively. The feeding block 510 may feed a side of the second antenna radiator 522 away from the second notch 5223. That is, the side of the second antenna radiator 522 away from the second notch 5223 may be spaced from the feeding block 510 by less than the predetermined coupling spacing.
In an example, the line widths of the first antenna radiator 521 and the second antenna radiator 522 shown in fig. 10 may be 1mm, and the first antenna radiator 521 and the second antenna radiator 522 may implement an operating frequency band of 4.4 to 5GHz, for example. For example, the antenna on the keyboard may operate in the N79 frequency band.
In an example, the line widths of the first antenna radiator 521 and the second antenna radiator 522 shown in fig. 10 may be greater than 1mm, and the first antenna radiator 521 and the second antenna radiator 522 may implement an operating band of 5 to 7GHz, for example. For example, the antenna on the keyboard may operate at WIFI 5G, WIFI 6G.
In an example, the line widths of the first antenna radiator 521 and the second antenna radiator 522 shown in fig. 10 may be smaller than 1mm, and the first antenna radiator 521 and the second antenna radiator 522 may implement, for example, an operating frequency band of 3.3GHz to 4.2 GHz. For example, the antenna on the keyboard may operate in the N77 frequency band.
In an example, the line widths of the first antenna radiator 521 and the second antenna radiator 522 shown in fig. 11 or fig. 12 may be about 1mm, and the first antenna radiator 521 and the second antenna radiator 522 may implement, for example, an operating frequency band of 2.4GHz to 2.5 GHz. For example, the antenna on the keyboard may operate in the WIFI 2.4G band or bluetooth.
Fig. 13 and 14 are schematic structural diagrams of a keyboard 300 according to an embodiment of the present application. Unlike the keypad 300 shown in fig. 5, the keypad 300 may include an antenna including a feeding unit, a feeding part 510, a first antenna radiator 521, a second antenna radiator 522, and a third antenna radiator 523.
As shown in fig. 13, the feeding means 510 may include a first segment (or branch) 514, a second segment (or branch) 515, and a third segment (or branch) 516. The first segment 514 is collinear with the second segment 515, and the first segment 514 is connected to the second segment 515 to form a first edge of the feeding member 510. The third segment 516 is vertically disposed with respect to both the first and second segments 514 and 515, and the third segment 516 is connected to the first and second segments 514 and 515 at a position where the first and second segments 514 and 515 intersect, so that the third segment 516 may form a second edge portion of the feeding part 510, which is vertically disposed with respect to the first edge portion. Thus, the feeding part 510 may have a "T" shape.
As can be seen from the examples of fig. 6 to 9, as shown in fig. 13, the open end of the first segment 514 (i.e., the first end of the feeding part 510) may form a first gap 511 with the keyboard frame 320, or the open end of the first segment 514 may form a first gap 511 with the above-mentioned remaining first frame layer 911. The open end of the second segment 515 (i.e., the second end of the feeding member 510) may form a second space 512 with the keyboard frame 320, or the open end of the second segment 515 may form a second space 512 with the remaining first frame layer 911. The open end of the third segment 516 (i.e., the third end of the feeding means 510) may form a third space 513 with the keypad frame 320, or the open end of the third segment 516 may form a third space 513 with the above-mentioned remaining first frame layer 911.
Optionally, the keyboard 300 may further include a second insulating member, a third insulating member, and a fifth insulating member; the second insulating member is located within the first space 511; the third insulating member is located within the second space 512; the fifth insulating member is located within the third space 513. That is, the open end of the first section 514 is directly connected to the keyboard frame 320 through the second insulating member; the open end of the second section 515 is directly connected to the keyboard frame 320 through a third insulating member; the open end of the third segment 516 is directly connected to the keyboard frame 320 through a fifth insulating member.
Referring to fig. 13 and 14, the keyboard frame 320 may include a first keyboard through hole 321, a second keyboard through hole 322, and a third keyboard through hole 323. The keyboard 300 may include a first keycap 311, a second keycap 312, and a third keycap 313. The first key cap 311 may correspond to the first keyboard through hole 321, and the first key cap 311 may be connected to the keyboard base 330 by a spring. The second key cap 312 may correspond to the second keyboard through hole 322, and the second key cap 312 may be connected to the keyboard base 330 by a spring. The third key cap 313 may correspond to the third key pad through hole 323, and the third key cap 313 may be connected to the keyboard base 330 by a spring.
In one example, as shown in fig. 13 and 14, the first keyboard via 321 may be located on a first row of the keyboard frame 320, and the second keyboard via 322 and the third keyboard via 323 may both be located on a second row of the keyboard frame 320, the first row being adjacent to the second row of the keyboard frame 320. Alternatively, the first keyboard through hole 321 may be located on the same column of the keyboard frame 320 as the second keyboard through hole 322 or the third keyboard through hole 323. Alternatively, the first keyboard through hole 321 may be located between the first row where the second keyboard through hole 322 is located and the second row where the third keyboard through hole 323 is located.
In another example, the first keyboard via 321 may be located on a first column of the keyboard frame 320, the second keyboard via 322 and the third keyboard via 323 may be both located on a second column of the keyboard frame 320, and the first column and the second column are adjacent two columns of the keyboard frame 320. Alternatively, the first keyboard through holes 321 may be located on the same row of the keyboard frame 320 as the second keyboard through holes 322 or the third keyboard through holes 323. Alternatively, the first keyboard via 321 may be located between the first row where the second keyboard via 322 is located and the second row where the third keyboard via 323 is located.
Referring to fig. 13 and 14, the first key cap 311 may be provided with a first antenna radiator 521, the second key cap 312 may be provided with a second antenna radiator 522, and the third key cap 313 may be provided with a third antenna radiator 523. The distance between the first keyboard through hole 321 and the feeding part 510, the distance between the second keyboard through hole 322 and the feeding part 510, and the distance between the third keyboard through hole 323 and the feeding part 510 are all smaller than a preset threshold (for example, the width of the feeding part 510). Accordingly, the feeding unit 510 may couple and feed the first antenna radiator 521, the second antenna radiator 522, and the third antenna radiator 523.
With reference to fig. 13 and 14, the first and second sections 514 and 515 of the feeding member 510 may feed the first antenna radiator 521; the first and third segments 514 and 516 of the feeding part 510 may feed the second antenna radiator 522; the second and third segments 515, 516 of the feeding part 510 may feed the third antenna radiator 523. That is, the first section 514 may be located between the first and second keyboard vias 321, 322, and the second section 515 may be located between the first and third keyboard vias 321, 323. The third segment 516 may be located between the second keyboard through hole 322 and the third keyboard through hole 323. The position of the feeding part 510 connected to the feeding source may be, for example, between the first section 514 and the second section 515.
Fig. 14 is a combination structure of a first antenna radiator 521, a second antenna radiator 522, and a third antenna radiator 523 according to an embodiment of the present application. In the example shown in fig. 14, the first antenna radiator 521, the second antenna radiator 522, and the third antenna radiator 523 may each have a loop structure. As can be seen from the examples shown in fig. 11 and 12, in other examples, at least one of the first antenna radiator 521, the second antenna radiator 522, and the third antenna radiator 523 may include a gap, and both ends of the gap may be two ends of the antenna radiator.
In order to make the antenna have a relatively wide bandwidth, the resonant frequencies of the first antenna radiator 521, the second antenna radiator 522, and the third antenna radiator 523 are different, and thus the structures of the first antenna radiator 521, the second antenna radiator 522, and the third antenna radiator 523 may be different. For example, the first, second, and third antenna radiators 521, 522, and 523 may have different line widths. As another example, the first antenna radiator 521, the second antenna radiator 522, and the third antenna radiator 523 include both antenna radiators having a ring structure and antenna radiators having notches.
Fig. 15 and 16 are schematic structural diagrams of a keyboard 300 according to an embodiment of the present application. Unlike the keyboard 300 shown in fig. 13 and 14, the first antenna radiator 521, the second antenna radiator 522, and the third antenna radiator 523 may be disposed on the same row of the keyboard frame 320. Alternatively, in other examples, the first antenna radiator 521, the second antenna radiator 522, and the third antenna radiator 523 may be disposed on the same column of the keyboard frame 320.
As shown in fig. 15, the feeding means 510 may include a first segment 514, a second segment 515, and a third segment 516. The first 514, second 515, and third 516 segments are collinear, and the second segment 515 is connected between the first 514 and third 516 segments. The first, second and third segments 514, 515, 516 may thus form one edge of the feeding member 510. Thus, the feeding part 510 may have a line shape.
As can be seen from the examples of fig. 6 to 9, as shown in fig. 15, the open end of the first segment 514 (i.e., the first end of the feeding part 510) may form a first gap 511 with the keyboard frame 320, or the open end of the first segment 514 may form a first gap 511 with the above-mentioned remaining first frame layer 911. The open end of the third segment 516 (i.e., the second end of the feeding member 510) may form the second space 512 with the keyboard frame 320, or the open end of the third segment 516 may form the second space 512 with the remaining first frame layer 911. Any one of the first, second, and third segments 514, 515, 516 may form a third space 513 with the keyboard frame 320, or alternatively, may form a third space 513 with the remaining first frame layer 911. The region where the first section 514 is connected to the second section 515, or the region where the second section 515 is connected to the third section 516, may form a fourth space 517 with the keyboard frame 320.
Optionally, the keyboard 300 may further include a second insulating member, a third insulating member, a fifth insulating member, and a sixth insulating member; the second insulating member is located within the first space 511; the third insulating member is located within the second space 512; the fifth insulating member is located within the third space 513; the sixth insulating member is positioned within the fourth space 517. That is, the open end of the first section 514 is directly connected to the keyboard frame 320 through the second insulating member; the open end of the second section 515 is directly connected to the keyboard frame 320 through a third insulating member; any one of the first, second and third segments 514, 515, 516 is directly connected to the keyboard frame 320 through a fifth insulating member; the region where the first section 514 is connected to the second section 515, or the region where the second section 515 is connected to the third section 516, is directly connected to the keyboard frame 320 through the sixth insulating member.
Referring to fig. 15 and 16, the keyboard frame 320 may include a first keyboard through hole 321, a second keyboard through hole 322, and a third keyboard through hole 323. The keyboard 300 may include a first keycap 311, a second keycap 312, and a third keycap 313. The first key cap 311 may correspond to the first keyboard through hole 321, and the first antenna radiator 521 may be disposed on the first key cap 311. The second key cap 312 may correspond to the second keyboard through hole 322, and the second antenna radiator 522 may be disposed on the second key cap 312. The third key cap 313 may correspond to the third key pad through hole 323, and the third key cap 313 may be provided with a third antenna radiator 523. The distance between the first keyboard through hole 321 and the feeding part 510, the distance between the second keyboard through hole 322 and the feeding part 510, and the distance between the third keyboard through hole 323 and the feeding part 510 are all smaller than a preset threshold (for example, the width of the feeding part 510). Thus, the feeding part 510 may couple feeds for the first antenna radiator 521, the second antenna radiator 522, and the third antenna radiator 523. The position of the feeding part 510 connected to the feeding source may be, for example, the middle part of the feeding part 510.
In one example, as shown in fig. 15 and 16, the first, second, and third keyboard through holes 321, 322, and 323 may be located on the same row of the keyboard frame 320. Accordingly, the first antenna radiator 521, the second antenna radiator 522, and the third antenna radiator 523 may be disposed on the same row of the keyboard frame 320.
In another example, the first, second, and third keyboard through holes 321, 322, and 323 may be located on the same column of the keyboard frame 320. Accordingly, the first antenna radiator 521, the second antenna radiator 522, and the third antenna radiator 523 may be disposed on the same column of the keyboard frame 320.
With reference to fig. 15 and 16, the first segment 514 of the feeding member 510 may feed the first antenna radiator 521; the second segment 515 of the feeding means 510 may feed the second antenna radiator 522; the third segment 516 of the feeding means 510 may feed the third antenna radiator 523. That is, the feeding part 510 may be located at the same side of the first, second, and third keypad through holes 321, 322, 323.
Fig. 16 is a combination structure of a first antenna radiator 521, a second antenna radiator 522, and a third antenna radiator 523 according to an embodiment of the present application. In the example shown in fig. 16, the first antenna radiator 521, the second antenna radiator 522, and the third antenna radiator 523 may each have a loop structure. As can be seen from the examples shown in fig. 11 and 12, in other examples, at least one of the first antenna radiator 521, the second antenna radiator 522, and the third antenna radiator 523 may include a gap, and both ends of the gap may be two ends of the antenna radiator.
In order to make the antenna have a relatively wide bandwidth, the resonant frequencies of the first antenna radiator 521, the second antenna radiator 522, and the third antenna radiator 523 are different, and thus the structures of the first antenna radiator 521, the second antenna radiator 522, and the third antenna radiator 523 may be different. For example, the first, second, and third antenna radiators 521, 522, and 523 may have different line widths. As another example, the first antenna radiator 521, the second antenna radiator 522, and the third antenna radiator 523 include both antenna radiators having a ring structure and antenna radiators having notches.
Fig. 17 and fig. 18 are schematic structural diagrams of a keyboard 300 according to an embodiment of the present application. Unlike the keypad 300 shown in fig. 13, the keypad 300 may include an antenna including a feeding unit, a feeding part 510, a first antenna radiator 521, a second antenna radiator 522, a third antenna radiator 523, and a fourth antenna radiator 524.
As shown in fig. 17, the feeding means 510 may include a first segment 514 (or branch), a second segment 515 (or branch), a third segment 516 (or branch), a fourth segment 518 (or branch). The first segment 514 may be disposed vertically relative to the second segment 515. The third segment 516 may be disposed vertically relative to the fourth segment 518. The second segment 515 may be collinear with the third segment 516, and the connection of the second segment 515 to the third segment 516 may form a first edge portion of the feeding member 510. The first and fourth segments 514, 518 may be located on either side of the first edge. The first segment 514 is located on a first side of the first edge and is located closer to an end of the second segment 515. The fourth segment 518 may be located on a second side of the first edge and at an end closer to the third segment 516. The first and fourth segments 514, 518 may thus form a second and third side portion, respectively, of the feeding means 510, which may each be arranged perpendicularly with respect to the first side portion.
As can be seen from the examples of fig. 6 to 9, as shown in fig. 17, the open end of the first segment 514 (i.e., the first end of the feeding part 510) may form a first gap 511 with the keyboard frame 320, or the open end of the first segment 514 may form a first gap 511 with the above-mentioned remaining first frame layer 911.

Accordingly, the feeding member 510 may couple and feed the first antenna radiator 521, the second antenna radiator 522, the third antenna radiator 523, and the fourth antenna radiator 524. The position of the feeding part 510 connected to the feeding source may be, for example, a position where the first section 514 is connected to the second section 515, or a position where the third section 516 is connected to the fourth section 518, or a middle part of the feeding part 510.

Fig. 18 is a combination structure of a first antenna radiator 521, a second antenna radiator 522, a third antenna radiator 523, and a fourth antenna radiator 524 according to an embodiment of the present disclosure. In the example shown in fig. 18, the first antenna radiator 521, the second antenna radiator 522, the third antenna radiator 523, and the fourth antenna radiator 524 may each have a ring structure. As can be seen from the examples shown in fig. 11 and 12, in other examples, at least one of the first antenna radiator 521, the second antenna radiator 522, the third antenna radiator 523, and the fourth antenna radiator 524 may include a gap, and two ends of the gap may be located at two sides of the gap.
In order to make the antenna have a relatively wide bandwidth, the resonant frequencies of the first, second, third, and fourth antenna radiators 521, 522, 523, and 524 are different, and thus the structures of the first, second, third, and fourth antenna radiators 521, 522, 523, and 524 may be different. For example, the first, second, third, and fourth antenna radiators 521, 522, 523, and 524 may have different line widths. As another example, the first antenna radiator 521, the second antenna radiator 522, the third antenna radiator 523, and the fourth antenna radiator 524 include both antenna radiators having a ring structure and antenna radiators having notches.
The dashed lines in fig. 19 show the return loss of the antenna 1 including the feeding means 510, excluding other antenna radiators. The solid line in fig. 19 shows the return loss of the antenna 2 comprising the feeding block 510, one antenna radiator and no other antenna radiator. The number of resonance low points of the antenna 1 is small and the return loss is large. The antenna 2 can have relatively low return loss within 5.5-6 GHz, and the number of resonance low points of the antenna 2 can be relatively large. That is to say, the number of the antenna radiators of the antenna is increased, which is beneficial to widening the bandwidth of the antenna and improving the antenna efficiency of the antenna. In the examples shown in fig. 17 and 18, the feeding component 510, the first antenna radiator 521, the second antenna radiator 522, the third antenna radiator 523, and the fourth antenna radiator 524 may generate different resonances, respectively, which is beneficial for covering a relatively wide bandwidth (e.g., N77 operating band).
In an example, the line widths of the first antenna radiator 521 and the second antenna radiator 522 shown in fig. 18 may be 1mm, and the first antenna radiator 521 and the second antenna radiator 522 may implement an operating frequency band of 4.4 to 5GHz, for example. For example, the antenna on the keyboard may operate in the N79 frequency band.
In an example, the line widths of the first antenna radiator 521 and the second antenna radiator 522 shown in fig. 18 may be greater than 1mm, and the first antenna radiator 521 and the second antenna radiator 522 may implement an operating band of 5 to 7GHz, for example. For example, the antenna on the keyboard may operate at WIFI 5G, WIFI 6G.
In an example, the line widths of the first antenna radiator 521 and the second antenna radiator 522 shown in fig. 18 may be smaller than 1mm, and the first antenna radiator 521 and the second antenna radiator 522 may implement, for example, an operating frequency band of 3.3GHz to 4.2 GHz. For example, the antenna on the keyboard may operate in the N77 frequency band.
In an example, referring to fig. 18, the line widths of the first antenna radiator 521 and the second antenna radiator 522 may be about 1mm, at least one of the first antenna radiator 521 and the second antenna radiator 522 may include the gap shown in fig. 11 or 12, and the first antenna radiator 521 and the second antenna radiator 522 may implement an operating band of 2.4GHz to 2.5GHz, for example. For example, the antenna on the keyboard may operate in the WIFI 2.4G band or bluetooth.
Fig. 20 shows a return loss, Smith (Smith) chart of the antenna as shown in fig. 17, 18. The antenna can have relatively low return loss within 3.3-4.2 GHz. As can be seen from the figure, the Smith chart is relatively convergent in 3.3-4.2 GHz, and has the characteristics of a broadband antenna.
Fig. 21 shows the antenna efficiency of the antenna shown in fig. 17 and 18. The average efficiency of the antenna in 3.15-4.2 GHz is about-6.5 dB, namely the antenna has relatively high antenna efficiency in 3.15-4.2 GHz.

In order to make the antenna have a relatively wide bandwidth, the resonant frequencies of the first, second, third, and fourth antenna radiators 521, 522, 523, and 524 are different, and thus the structures of the first, second, third, and fourth antenna radiators 521, 522, 523, and 524 may be different. For example, the first, second, third, and fourth antenna radiators 521, 522, 523, and 524 may have different line widths.

It can be seen that the feeding unit 510 can couple feeding to the first antenna radiator 521.
As can be seen from the examples of fig. 6 to 9, as shown in fig. 25, the feeding unit 510 may form a plurality of intervals 530 with the keyboard frame 320, and the intervals 530 may cut off signal transmission between the feeding unit 510 and the keyboard frame 320.

As can be seen from the examples shown in fig. 11 and 12, in other examples, the first antenna radiator 521 may include a gap, and the two ends of the first antenna radiator 521 may be located on two sides of the gap.
As can be seen from the examples shown in fig. 5 to fig. 26, by providing a plurality of antenna radiators on a plurality of keycaps, the plurality of antenna radiators are fed by the same feeding component, which is beneficial to achieving excellent antenna performance (such as improving broadband and high antenna efficiency), and can implement operating frequency bands such as N77, N79, WIFI 5G, or WIFI 6G. In addition, the number of the antenna radiators is increased, so that the bandwidth of the antenna can be further widened, and the antenna can work on multiple working frequency bands, for example, the antenna shown in fig. 25 and 26 can work on a WIFI 5G frequency band and can also work on a WIFI6G frequency band. Moreover, when a user touches one of the key caps with a finger of the user using the keyboard 300, the antenna radiators on the other key caps can still work normally, so that the influence of the finger on the performance of the antenna on the keyboard 300 is reduced.
Fig. 27 is a schematic structural diagram of a keyboard 300 according to an embodiment of the present application. The keyboard 300 may include one or more antennas as shown in fig. 5 to 19 and 22 to 26, the antenna may operate in any frequency band such as N77/N79/WIFI 5G/WIFI 6G/bluetooth/Wi-Fi 2.4G, and the multiple antennas may operate in different frequency bands.
In one example, as shown in fig. 27, keyboard 300 may include antenna 701, antenna 702, antenna 703, antenna 704, antenna 705, antenna 706, antenna 707.
The antenna 701 may be, for example, an antenna as shown in fig. 5 to 12. The antenna 701 may operate, for example, in the N77/N79 frequency band.
The antenna 702 may be, for example, an antenna as shown in fig. 13-14. The antenna 702 may operate, for example, in the N77/N79 frequency band.

The antennas 704 and 705 may be antennas as shown in fig. 17 to 18, for example. The antennas 704 and 705 can work in any two frequency bands of N77/N79/WIFI 5G/WIFI6G, for example. Alternatively, the structure of the antenna radiator of the antenna 704 may be different from that of the antenna radiator of the antenna 705.
The antenna 706 may be, for example, an antenna as shown in fig. 22-24. Antenna 706 may operate, for example, in the WIFI 5G, WIFI6G frequency band.
The antenna 707 may be, for example, an antenna shown in fig. 25 to 26. Antenna 707 may operate, for example, in the Bluetooth/Wi-Fi2.4G band.
A barrier may be disposed around any antenna of the keyboard 300 to reduce interference between the antennas and increase isolation between the antennas. In one example, the keyboard frame 320 around the feeding component may be electrically connected with the keyboard backplane 330, for example, by screws or conductive glue, etc., to reduce interference of the external environment on the feeding component.
As can be seen from the example shown in fig. 27, the various antenna structures provided in the embodiments of the present application can be used to implement various operating frequency bands. That is, different antenna structures may implement different operating frequency bands. Therefore, the space of the keyboard can be effectively utilized, and diversified communication functions can be provided for the electronic equipment.
