Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of terminal devices, and in particular, to a notebook computer. Background Art

[0002] With the development of technology, consumers have higher and higher requirements for the appearance of electronic devices (such as notebook computers). A notebook computer, abbreviated as a notebook, also known as a portable computer, a laptop, a palmtop computer or a laptop computer, is characterized by a small body and is more convenient to carry than a desktop computer. It is a small and portable personal computer. As a daily office electronic device, consumers have stronger and stronger requirements for its narrow bezel, all-metal texture and touch.

[0003] Since notebook computers usually need to be provided with radio frequency antennas, the structural design of narrow-bezel and all-metal notebook computers poses great challenges to the field of radio frequency antennas. For all-metal notebook computers, there are usually two common antenna designs. The first is to open a window on the metal housing on the screen side or the system side so that the antenna can radiate. The second is to design the antenna in the plastic hinge cover.

[0004] However, for narrow-bezel notebook computers, adopting the first above-mentioned scheme will damage the integrity of the metal of the notebook computer and affect the all-metal texture of the notebook computer. Adopting the second above-mentioned scheme can meet the design of all-metal notebook computers, but there will be a section of plastic space under the screen in this scheme and it is impossible to achieve a narrower bezel. Moreover, this scheme usually requires a notebook computer to have a hinge cover with a relatively large size radius, which affects the appearance of the product and is not conducive to the all-metal design of the product. Summary of the Invention

[0005] The embodiments of the present application provide a notebook computer, which can greatly reduce the influence of the antenna on the all-metal texture of the notebook computer and is conducive to the design of the narrow bezel of the notebook computer.

[0006] An embodiment of the present application provides a laptop computer, including: a display and a main body. One side of the display is hinged to one side of the main body. It is characterized in that the main body includes: a first metal housing, a heat dissipation device, and an antenna assembly. The heat dissipation device and the antenna assembly are both disposed within the first metal housing. The antenna assembly includes: an antenna bracket, an excitation source, a grounding area, a feeding point, and a flexible conductive member. A first ventilation opening is formed in a side of the first metal housing. The antenna bracket is formed with at least one ventilation channel, and the ventilation channel is disposed opposite to and close to the first ventilation opening. The antenna bracket has a first surface facing the display side and a second surface facing away from the display side. The excitation source and the feeding point are disposed on the second surface of the antenna bracket. The feeding point is connected to the excitation source. At least a grounding area is disposed on the second surface of the antenna bracket. The excitation source is connected to the grounding area. The flexible conductive member connects the grounding area to the first metal housing, and the flexible conductive member is located on a side of the excitation source away from the first ventilation opening. A radiation opening is formed or a non-metal member is disposed in an area of the first metal housing facing the excitation source.

[0007] In the laptop computer provided by the embodiment of the present application, by disposing the antenna assembly at the first ventilation opening of the main body, the antenna assembly does not occupy the position at the display end, thereby realizing a narrow-bezel full-screen and all-metal design at the display end, and does not occupy other spaces inside the main body, making the design of the laptop computer more beautiful. Moreover, the excitation source is located on a surface of the antenna bracket facing the D shell (it can be understood that when the laptop computer is placed on a desktop, the excitation source is located on a surface of the antenna bracket facing the desktop), which is beneficial to the all-metal design of the C shell and improves the aesthetic appearance of the laptop computer. In addition, in actual use, the C shell is generally a cover with a folded edge fastened on the D shell. The all-metal setting of the C shell can improve the overall strength of the C shell. Furthermore, the flexible conductive member is located on a side of the excitation source away from the first ventilation opening. The flexible conductive member can shield the signal interference of the laptop computer body to the excitation source and block electromagnetic noise. Compared with the method of disposing the excitation source on a surface of the antenna bracket facing or away from the first ventilation opening, there is no need to set a metal barrier to shield the signal interference to the excitation source, which is beneficial to the lightening and thinning of the laptop computer. At the same time, the radiation surface of the excitation source faces the D shell, and a radiation opening is formed or a non-metal member is disposed in an area of the D shell corresponding to the excitation source, so there is no need to set a plastic outer frame as the appearance surface of the C shell or the D shell, which is beneficial to the all-metal design of the C shell and the D shell.

[0008] In a possible implementation, the first metal housing includes a C-shell close to the display side and a D-shell far from the display side. The connection between the D-shell and the side of the first metal housing is an inclined surface. The non-metal part is arranged on the inclined surface, and the second surface of the antenna bracket is arranged in imitation of the inclined surface.

[0009] In this way, it is beneficial to the signal radiation of the excitation source and can avoid the signal being blocked by the desktop.

[0010] In a possible implementation, a second ventilation opening is provided on the non-metal part. The excitation source and the antenna bracket are respectively provided with a third ventilation opening and a fourth ventilation opening, and at least part of the fourth ventilation opening and the third ventilation opening are communicated with the ventilation channel.

[0011] On the one hand, it can enable the antenna assembly to assist the first ventilation opening in air intake or exhaust. On the other hand, it can improve the appearance beautification degree of the notebook computer.

[0012] In a possible implementation, a grounding area is provided on the first surface of the antenna bracket. The grounding area on the first surface of the antenna bracket is connected to the grounding area on the second surface of the antenna bracket. A flexible conductive member is provided on the grounding area of the first surface of the antenna bracket to be connected to the first metal housing.

[0013] In this way, the grounding area of the antenna can be increased, thereby improving the overall performance of the antenna.

[0014] In a possible implementation, electrical connection parts are provided on both end faces of the antenna bracket perpendicular to the ventilation channel and on the columns of each ventilation channel far from the first ventilation opening side. The electrical connection parts connect the grounding area on the first surface of the antenna bracket and the grounding area on the second surface of the antenna bracket to form a cavity-backed antenna.

[0015] Compared with traditional antennas, the cavity-backed antenna does not require a complex feeding network, has a simple structure and is easy to produce and process, and is beneficial to improving the directivity of the antenna and sharpening the beam width. And it is beneficial to reduce the size of the radiation opening provided on the first metal housing.

[0016] In a possible implementation, an excitation conductor is provided on the side wall of the ventilation channel. One end of the excitation conductor is connected to the excitation source, and the other end of the excitation conductor extends towards the first surface of the antenna bracket.

[0017] In this way, the metal coupling amount between the side wall of the C-shell and the surface of the C-shell provided with the keyboard can be increased, and the antenna efficiency and bandwidth can be effectively improved or compensated.

[0018] In a possible implementation, there are at least two antenna components, and the two antenna components are arranged along two adjacent sides of the laptop.

[0019] In this way, the directivity of the antenna can be improved, and there are certain improvements in terms of comprehensive efficiency, directivity coefficient, isolation, and OTA index compared with traditional antennas.

[0020] In a possible implementation, the antenna formed by the excitation source, the grounding area, and the feeding point is an FPC antenna or an LDS antenna.

[0021] In a possible implementation, the excitation source is arranged with a gap from the first metal housing. This can increase the clearance area of the antenna.

[0022] In a possible implementation, the first ventilation opening is arranged on the side of the first metal housing hinged to the display and / or on the side adjacent to the side where the first metal housing is hinged to the display. This is beneficial to improving the user experience. BRIEF DESCRIPTION OF THE DRAWINGS

[0049] The terms used in the implementation manners part of this application are only used to explain the specific embodiments of this application, rather than intended to limit this application. The implementation manners of the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0050] In the embodiments of this application, the term "including", "comprising" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "including one" does not exclude the existence of additional identical elements in the process, method, article or device including that element.

[0051] Figure 1 The structural schematic diagram of the laptop 100 provided for an embodiment of this application, Figure 2 The structural schematic diagram of the laptop 100 provided for an embodiment of this application, refer to Figure 1 and Figure 2 as shown, Figure 1 is the schematic diagram of the closed state of the laptop 100, Figure 2 is the schematic diagram of the unfolded state of the laptop 100. The laptop 100 provided by the embodiments of this application includes: a display 200 and a host 300.

[0052] Specifically, the display 200 may include a display screen 210 and a second metal housing 220. The display screen 210 is used to display images, videos, etc. The display screen 210 may be a flexible display screen or a rigid display screen. For example, the display screen 210 may be an organic light-emitting diode (OLED) display screen, an active-matrix organic light-emitting diode (AMOLED) display screen, a mini organic light-emitting diode display screen, a micro organic light-emitting diode display screen, a microorganic light-emitting diode display screen, a quantum dot light-emitting diodes (QLED) display screen, or a liquid crystal display (LCD).

[0053] The second metal housing 220 is used to protect the display screen 210. The second metal housing 220 may cover the edge of the display screen 210 for one week and the back of the display screen 210. In some embodiments of the present application, the second metal housing 220 may also be divided into a shell A and a shell B.

[0054] The host 300 may include a host body 310, a keyboard 320, and a touchpad 330. The keyboard 320 and the touchpad 330 are disposed on the host body 310. The keyboard 320 is used to input instructions or data. One working mode of the touchpad 330 is to be used as a mouse, and the touch action of the user's finger (including actions such as sliding and clicking) is used to control the action of the cursor on the display 200 to perform operations such as "cursor navigation", "selection", and "confirmation" of the mouse. This working mode of the touchpad 330 is referred to as the mouse working mode in the embodiments of the present application. It should be noted that in the mouse working mode, the touchpad 330 may replace the mouse to control the laptop 100, or may work in cooperation with the mouse to improve the portability of the laptop 100.

[0055] Figure 3 It is a partial exploded structural schematic diagram of the laptop 100 provided by an embodiment of the present application. Refer to Figure 3As shown, the host body 310 may include: a first metal housing 311 and electronic components accommodated in the first metal housing 311. The electronic components include, but are not limited to, a main board 313, a battery 312, a radiator, a processor, a memory, and so on. The host body 310 is used to control the display 200 to display images and videos according to instructions or data input by the keyboard 320, and is also used to control the cursor movement on the display 200 according to touch actions input by the touchpad 330.

[0056] In some embodiments of the present application, the first metal housing 311 may include: a C shell 3111 and a D shell 3112 (as Figure 3 shown). It should be added that in the notebook computer 100, the housing is generally divided into an A shell, a B shell, a C shell 3111, and a D shell 3112. The A shell refers to the back cover of the display screen 210 (i.e., Figure 1 the uppermost cover body in the figure), the B shell refers to the front frame of the screen (i.e., the housing surrounding the edge of the display screen 210 for one week), the C shell 3111 refers to the upper cover of the host 300 (i.e., the housing surrounding the edges of the keyboard 320 and the touchpad 330 for one week), and the D shell 3112 refers to the lower cover of the host 300 (i.e., the bottommost housing of the notebook computer 100 placed on the desktop). It can be understood that the second metal housing 220 can be divided into an A shell and a B shell, and of course, it can also be integrally formed. The same is true for the first metal housing 311. The first metal housing 311 can be divided into a C shell 3111 and a D shell 3112, and of course, it can also be integrally formed. Here, "integrally formed" means that two components are formed into an inseparable whole through a process.

[0057] One side of the host body 310 is hinged to one side of the display 200. The present application does not limit the form of the hinge between the host body 310 and the display 200. Exemplarily, as Figure 2 and Figure 3 shown, the notebook computer 100 uses a vertical axis form to hinge the C shell 3111 to the second metal housing 220 of the display 200, and the notebook computer 100 can be switched between an open state and a closed state. When the notebook computer 100 is in the open state, the display 200 and the host 300 form an angle greater than 0° and less than 180° (for example Figure 2 shown). When the notebook computer 100 is in the closed state, the display 200 covers the host 300, and the display surface of the display screen 210 faces the keyboard 320 of the host 300 (as Figure 1 shown).

[0058] Continue to refer to Figure 3As shown in the figure, in the laptop computer 100 provided by the embodiment of the present application, the electronic components in the host body 310 may include: a battery 312 and a motherboard 313. The battery 312 can provide electrical energy for the motherboard 313 and the display screen 210, and the motherboard 313 is connected to other electronic components and the display screen 210 to control other electronic components and the display screen 210.

[0059] Generally, an antenna unit, such as a WIFI antenna, also needs to be set in the laptop computer 100. In the related art, for a laptop computer 100 with a fully metalized design, the antenna unit is usually designed in the plastic hinge cover at the hinge of the host body 310 and the display 200 to reduce the influence on the metal appearance of the second metal housing 220 of the display 200 and the first metal housing 311 of the host body 310. However, compared with the laptop computer 100 with a vertical axis, the solution with a plastic hinge cover will leave a section of plastic space under the display screen 210, making it impossible for the laptop computer 100 to have a narrower border. Moreover, the plastic hinge cover will also affect the fully metal appearance of the laptop computer 100. When the antenna unit is designed in the second metal housing 220 of the display 200 or in the first metal housing 311 of the host body 310, windows need to be opened on the second metal housing 220 and the C shell to enable the antenna unit to radiate. In this way, the integrity of the metal of the laptop computer 100 will be damaged, affecting the fully metal texture of the laptop computer 100.

[0060] To solve the above problems, the embodiment of the present application provides a laptop computer 100. The antenna assembly 400 is arranged at the ventilation opening of the laptop computer 100 and radiates through part of the shell surface gap of the D shell 3112, greatly reducing the influence of the antenna on the metal housing, which is beneficial to the narrow border and fully metalized design.

[0061] The following will make a detailed description of the laptop computer 100 provided by the embodiment of the present application with reference to the accompanying drawings and specific embodiments.

[0062] Refer to Figure 2 and Figure 3 As shown in the figure, the host body 310 further includes: a heat dissipation device 314 and an antenna assembly 400 arranged in the first metal housing 311. The function of the heat dissipation device 314 is to dissipate heat from the electronic components in the host body 310. Heat dissipation fins 3141 can also be arranged at the air outlet of the heat dissipation device 314 to improve the heat dissipation performance of the heat dissipation device 314. The heat dissipation device 314 can adopt a commonly used fan, etc. The number and installation position of the heat dissipation device 314 in the host body 310 are not limited in the present application. Exemplarily, as Figure 3 shown in the figure, in some embodiments of the present application, a heat dissipation device 314 is arranged on each side of the motherboard 313 close to the hinge side of the display 200.

[0063] Figure 4 Schematic diagram of the structure of the antenna assembly 400 provided by an embodiment of the present application. Refer to Figure 4 and in combination with Figure 3 As shown, the antenna assembly 400 includes: an antenna bracket 410, an excitation source 420, a grounding area 430, a feeding point 440, and a flexible conductive member 450. The antenna bracket 410 can be a plastic bracket or a bracket formed by nano-injection molding (NMT). The antenna form formed by the excitation source 420 and the feeding point 440 can be a flexible printed circuit (FPC) antenna or a laser-direct-structuring (LDS) antenna.

[0064] Specifically, a first ventilation opening 315 is formed in the side wall of the first metal housing 311. This ventilation opening can be an air inlet or an air outlet of the laptop 100. The support antenna is formed with at least one ventilation channel 411. Exemplarily, Figure 4 the support antenna is formed with seven ventilation channels 411 arranged side by side. The ventilation channels 411 are opposite to and close to the first ventilation opening 315. Here, "the ventilation channels 411 are close to the first ventilation opening 315" means that the ventilation channels 411 are arranged as close as possible to the first ventilation opening 315, so that the air flow entering from the outside through the first ventilation opening 315 can flow into the interior of the laptop 100 through the ventilation channels 411, or the hot air blown out by the heat dissipation device 314 can flow out through the ventilation channels 411 from the first ventilation opening 315.

[0065] In some embodiments of the present application, the first ventilation opening 315 can be arranged on the side where the first metal housing 311 is hinged to the display 200 and / or on the side adjacent to the side where the first metal housing 311 is hinged to the display 200. It can be understood that the first ventilation opening 315 is arranged away from the user operation side, which is beneficial to improving the user experience.

[0066] Among them, the antenna bracket 410 has a first surface 412 facing the display 200 (i.e., the surface facing the C shell 3111 of the laptop 100) and a second surface 413 facing away from the display 200 (i.e., the surface facing the D shell 3112 of the laptop 100). Figure 5 Top view of a partial structure of the antenna assembly 400 provided by an embodiment of the present application. Figure 5 The top view of the antenna assembly 400 in is a top view with the D shell 3112 surface as the incident view angle. Refer to Figure 5 and in combination with Figure 4As shown, the excitation source 420 and the feeding point 440 are arranged on the second surface 413 of the antenna bracket 410. The feeding point 440 is connected to the excitation source 420. The feeding point 440 feeds a high-frequency signal through the antenna cable 340, and the other end of the antenna cable 340 can be connected to the main board 313 in the laptop 100. The excitation source 420 can be arranged at an interval from the first metal housing 311 to increase the clearance area of the antenna.

[0067] Among them, at least a grounding area 430 is arranged on the second surface 413 of the antenna bracket 410. The excitation source 420 is connected to the grounding area 430. The flexible conductive member 450 connects the grounding area 430 and the first metal housing 311. Exemplarily, the flexible conductive member 450 can be a conductive foam, etc. The flexible conductive member 450 connects the grounding area 430 on the second surface 413 of the antenna bracket 410 and the D shell 3112 of the laptop 100. And the flexible conductive member 450 is located on the side of the excitation source 420 away from the first vent 315. It can be understood that the flexible conductive member 450 is closer to the inside of the laptop body than the excitation source 420.

[0068] In addition, referring to Figure 3 As shown, a radiation port is opened or a non-metal member 350 is arranged in the area of the first metal housing 311 facing the excitation source 420 to avoid interference with the signal of the excitation source 420. Exemplarily, as Figure 3 shown, a non-metal member 350 (such as a plastic part) is arranged in the area of the first metal housing 311 facing the excitation source 420. On the one hand, it can avoid interference with the signal of the excitation source 420, and on the other hand, it is beneficial to the appearance beautification of the laptop 100. In addition, the non-metal member 350 can be sprayed with the same or similar color as the D shell 3112 to further improve the appearance beautification degree of the laptop 100.

[0069] It is understandable that the laptop computer 100 provided in the embodiment of the present application, by setting the antenna assembly 400 at the first vent 315 of the host body 310, can make the antenna assembly 400 not occupy the position of the display 200 end, thereby realizing the narrow frame full screen and full metal design of the display 200 end, and will not occupy other spaces inside the host body 310, so that the design of the laptop computer 100 is more beautiful. In addition, the excitation source 420 is located on the side of the antenna bracket 410 facing the D shell 3112 (it can be understood that when the laptop computer 100 is placed on the desktop, the excitation source 420 is located on the side of the antenna bracket 410 facing the desktop), which is conducive to the full metal design of the C shell 3111 and improves the appearance of the laptop computer 100. In addition, in actual use, the C shell 3111 is generally a cover body with a folded edge buckled on the D shell 3112, and the full metal setting of the C shell 3111 can improve the overall strength of the C shell 3111. Furthermore, the flexible conductive member 450 is located on the side of the excitation source 420 away from the first vent 315. The flexible conductive member 450 can shield the signal interference of the excitation source 420 from the body of the laptop 100 and block electromagnetic noise. Compared with the method in which the excitation source 420 is arranged on the side of the antenna bracket 410 facing or away from the first vent 315, it is not necessary to set a metal retaining wall to shield the signal interference of the excitation source 420, which is conducive to the lightweight and thinning of the laptop 100. At the same time, the radiation surface of the excitation source 420 faces the D shell 3112, and the area corresponding to the excitation source 420 on the D shell 3112 is provided with a radiation port or a non-metallic member 350, so it is not necessary to set a plastic frame as the appearance surface of the C shell 3111 or the D shell 3112, which is conducive to the full metal design of the C shell 3111 and the D shell 3112.

[0070] It should be noted that the full metal design of the laptop computer 100 mentioned in the present application does not mean that the shell of the laptop computer 100 is entirely made of metal, but means minimizing the use of other materials except metal. The most important thing is that the appearance of the A shell and the C shell is fully metalized to meet the design trend towards full metal shells.

[0071] Of course, this application does not stop there. Figure 6 A schematic cross-sectional view of a notebook computer 100 provided in an embodiment of the present application is shown in FIG. Figure 6 As shown, Figure 6 It can be regarded as a schematic diagram of the laptop computer 100 being turned upside down. In some embodiments of the present application, the first metal shell 311 may include: a C shell 3111 close to the display 200 side and a D shell 3112 away from the display 200 side. The connection between the D shell 3112 and the side of the first metal shell 311 is an inclined surface 31121, and the inclined surface 31121 may be an inclined plane or an inclined arc surface. Figure 6Taking the inclined surface 31121 as an example of the inclined plane for illustration. The second surface 413 of the antenna bracket 410 is configured to be in imitation of the inclined surface 31121. For example, when the inclined surface 31121 is an inclined plane, the second surface 413 of the antenna bracket 410 is correspondingly set as an inclined plane; when the inclined surface 31121 is an inclined arc surface, the second surface 413 of the antenna bracket 410 is correspondingly set as an inclined arc surface. In this way, it is beneficial to the signal radiation of the excitation source 420 and can avoid the signal being blocked by the desktop.

[0072] Figure 7 FIG. is a schematic structural diagram of the antenna assembly 400 of the laptop 100 provided by an embodiment of the present application. Refer to Figure 7 and in combination with Figure 4 shown, in some embodiments of the present application, a second ventilation opening 351 can be formed on the non-metal member 350. The excitation source 420 and the antenna bracket 410 are respectively provided with a third ventilation opening 421 and a fourth ventilation opening 414. At least a part of the fourth ventilation opening 414 and the third ventilation opening 421 communicate with the ventilation channel 411. On the one hand, it can enable the antenna assembly 400 to assist the first ventilation opening 315 in air intake or air outlet. On the other hand, it can improve the appearance beauty of the laptop 100 (for the effect diagram, refer to Figure 8 ). Of course, when the antenna assembly 400 does not need to assist the first ventilation opening 315 in air intake or air outlet, the second ventilation opening 351, the third ventilation opening 421 and the fourth ventilation opening 414 do not need to be formed.

[0073] Among them, refer to Figure 4 shown, that at least a part of the fourth ventilation opening 414 communicates with the third ventilation opening 421 means that a fourth ventilation opening 414 can also be formed on the second surface 413 of the antenna bracket 410 where the excitation source 420 is not provided. Here, the fourth ventilation opening 414 communicates with the ventilation channel 411 but does not communicate with the third ventilation opening 421. On the second surface 413 of the antenna bracket 410 where the fourth ventilation opening 414 and the excitation source 420 do not need to be provided, it can be cut off. For example Figure 4 the cut-off part 415 where the two ends of the antenna bracket 410 in FIG. are recessed relative to the middle part.

[0074] Among them, the present application does not limit the number and shape of the first ventilation opening 315, the second ventilation opening 351, the third ventilation opening 421 and the fourth ventilation opening 414. For example, the first ventilation opening 315, the second ventilation opening 351, the third ventilation opening 421 and the fourth ventilation opening 414 can all be one or more, and the shapes of the first ventilation opening 315, the second ventilation opening 351, the third ventilation opening 421 and the fourth ventilation opening 414 can be square holes, circular holes or waist-shaped holes, etc.

Exemplarily, as shown in Figure 10 shown, an electrical connection portion 460 may be provided on the surface of the antenna bracket 410 facing away from the first air outlet, and the electrical connection portion 460 connects the grounding area 430 on the first surface 412 of the antenna bracket 410 and the grounding area 430 on the second surface 413 of the antenna bracket 410. In this way, the grounding area of the antenna can be increased, thereby improving the overall performance of the antenna. In addition, a flexible conductive member 450 may also be provided on the grounding area 430 of the first surface 412 of the antenna bracket 410 to be connected to the first metal housing 311 (reference can be made to Figure 7 shown).

The electrical connection portions 460 connect the grounding area 430 on the first surface 412 of the antenna bracket 410 and the grounding area 430 on the second surface 413 of the antenna bracket 410 to form a cavity-backed antenna. The excitation source 420, the grounding area 430 and the electrical connection portion 460 form an interconnected whole.

[0077] Compared with traditional antennas, cavity-backed antennas do not require a complex feeding network, have a simple structure and are easy to produce and process, and are beneficial to improving the directivity of the antenna and sharpening the beam width. And it is beneficial to reduce the size of the radiation opening provided on the first metal housing 311.

[0078] Continuing to refer to Figure 4 shown, in some embodiments of the present application, an excitation conductor 470 is provided on the side of the ventilation channel 411. One end of the excitation conductor 470 is connected to the excitation source 420, and the other end of the excitation conductor 470 extends toward the first surface 412 of the antenna bracket 410. Exemplarily, as shown in Figure 4As shown, the excitation conductor 470 can be formed on the side wall of the ventilation channel 411 through FPC or LDS, and the excitation conductor 470 is connected to the excitation source 420 by using the electrical connection part 460. In this way, the metal coupling amount between the side wall of the C shell 3111 and the side of the C shell 3111 where the keyboard 320 is provided can be increased, and the antenna efficiency and bandwidth can be effectively improved or compensated. The number of the excitation conductors 470 in this application is not limited, and it can be one or multiple. The multiple excitation conductors 470 are respectively arranged on the side walls of each ventilation channel 411.

[0079] Continue to refer to Figure 3 As shown, in some embodiments of this application, the antenna assembly 400 is at least two, and the two antenna assemblies 400 are arranged along two adjacent sides of the notebook computer 100, and it can be understood that the two antenna assemblies 400 are vertically arranged.

Refer to Figure 12 and Figure 13 As shown, when the two antenna assemblies 400 are arranged along two adjacent sides of the notebook computer 100, the directivity of the antenna can be improved, and direction complementarity can be achieved in 2.4G / 5.5G. The antenna performance can be referred to Table 1 and Table 2. Table 1 shows the antenna efficiency and directivity coefficient, and Table 2 shows the OTA index. According to Table 1 and Table 2, it can be known that the two mutually perpendicular antennas have certain improvements in terms of comprehensive efficiency, directivity coefficient, isolation degree, and OTA index compared with the traditional antennas.
