Description

Antennas and electronic devices

[0001] This application claims priority to Chinese patent application filed on May 28, 2024, with application number 202410679999.0 and entitled "Antenna and Electronic Device", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of computer technology, specifically to an antenna and an electronic device. Background Technology

[0003] The antenna of a personal computer (PC) is located inside the PC. In order not to affect the performance of the antenna, non-metallic areas need to be set on the chassis. When the chassis is made of all-metal structural parts, non-metallic areas will affect the refinement of the PC's industrial design (ID). Summary of the Invention

[0004] This application provides an antenna and an electronic device designed to improve the sophistication of the electronic device's ID.

[0005] To achieve the above objectives, the embodiments of this application adopt the following technical solutions:

[0006] On one hand, this application provides an antenna including a first body and a first radiator. The first body is provided with multiple air outlet channels for connecting the outside of an electronic device with a cooling fan inside the electronic device. The first body includes a first surface, through which the air outlet channels pass and form an air outlet on the first surface. The first surface includes a radiation area and an air outlet area, with the air outlet located in the air outlet area and the radiation area surrounding the air outlet area. The first radiator is disposed in the radiation area.

[0007] This application provides an antenna that can be installed in an electronic device. The antenna includes a first body and a first radiator. The first body has an air outlet channel, one end of which penetrates a first surface to form an air outlet on the first surface. The air outlet is used to communicate with a heat dissipation vent, and the other end of the air outlet channel is used to communicate with a cooling fan. The cooling fan drives air through the air outlet channel and the air outlet, and exhausts it from the heat dissipation vent to achieve the function of heat dissipation. The first radiator is disposed in the radiation area on the first surface of the first body facing the heat dissipation vent, so that the first radiator can transmit or receive electromagnetic wave signals through the heat dissipation vent. The antenna performance can be achieved through the heat dissipation vent without affecting normal heat dissipation, avoiding the opening of windows on an all-metal electronic device, which would damage the integrity of the body components and improve the refinement of the electronic device's ID.

[0008] Meanwhile, the first radiator is located in the radiation zone, which surrounds the air outlet zone. This reduces the proportion of the radiation zone occupying the central area of ​​the heat dissipation vent, making the airflow through the air outlet channel and vent smoother and improving the heat dissipation efficiency of the electronic equipment.

[0009] In some embodiments, the radiation zone includes a first radiation zone and a second radiation zone, wherein the first radiation zone and the air outlet zone are spaced apart in the height direction of the first main body (i.e., the first radiation zone and the air outlet zone do not overlap in the height direction of the first main body), and the second radiation zone and the air outlet zone are spaced apart in the length direction of the first main body (i.e., the second radiation zone and the air outlet zone do not overlap in the length direction of the first main body); a first radiator is disposed in the first radiation zone and the second radiation zone.

[0010] With the above settings, while ensuring that the radiation area occupies the central area of ​​the heat dissipation port, the first radiation area and the air outlet area are spaced apart in the height direction of the first main body, and the second radiation area and the air outlet area are spaced apart in the length direction of the first main body. First radiators can be set in both the first and second radiation areas, which increases the number of first radiators in the antenna and can improve the performance of the antenna.

[0011] In some embodiments, the antenna further includes a first cable, one end of which is electrically connected to a first radiator, and the other end of which is used to connect to a motherboard in an electronic device for transmitting radio frequency signals to the first radiator or transmitting radio frequency signals received by the first radiator to the motherboard.

[0012] In some embodiments, the first body further includes a second surface adjacent to the first surface, the second surface being located on the side of the air outlet area away from the first radiation area, and the first cable being disposed on the second surface; the antenna further includes a Mylar sheet, the Mylar sheet covering the second surface.

[0013] With the above arrangement, the Mylar sheet covers the second surface. In the embodiment where the first cable can be disposed on the second surface, the Mylar sheet can cover the first cable to protect the first cable.

[0014] In some embodiments, the antenna further includes conductive foam covering the second surface, which can provide electrostatic protection for the antenna and act as a buffer between the antenna and the second housing when the antenna is mounted on the second housing.

[0015] In some embodiments, the antenna further includes a second body, a second radiator, and a second cable. The first body and the second body are spaced apart along the length of the first body. The second radiator is disposed on the second body. One end of the second cable is electrically connected to the second radiator for feeding power to the second radiator, and the other end of the second cable is connected to the first cable.

[0016] With the above configuration, in addition to the first main body and the first radiator, the antenna also includes a second main body and a second radiator, which increases the number of radiators in the antenna and improves the antenna performance.

[0017] On the other hand, this application embodiment also provides an electronic device, including a body assembly and an antenna. The body assembly has a first end and a second end disposed opposite to each other, and the first end is provided with a heat dissipation vent. The antenna includes a first body and a first radiator. The first body is disposed inside the body assembly and is disposed close to the first end. The first body includes a first surface facing the heat dissipation vent, and the first radiator is disposed on the first surface. The first body is provided with an air outlet channel. One end of the air outlet channel penetrates through the first surface and forms an air outlet on the first surface. The air outlet is connected to the heat dissipation vent, and the other end of the air outlet channel is used to connect to a cooling fan.

[0018] The electronic device provided in this application has a heat dissipation vent in its body assembly. The antenna includes a first main body and a first radiator. The first main body is located inside the body assembly and has an air outlet channel. One end of the air outlet channel penetrates a first surface to form an air outlet on the first surface, and the air outlet is connected to the heat dissipation vent. The other end of the air outlet channel is used to connect to a cooling fan. During the heat dissipation process of the electronic device, the cooling fan drives air through the air outlet channel and the air outlet, and exhausts the air from the heat dissipation vent to dissipate heat from the electronic device. The first radiator is disposed on the first surface of the first main body facing the heat dissipation vent, so that the first radiator can transmit or receive electromagnetic wave signals through the heat dissipation vent. This can achieve antenna performance without affecting the heat dissipation of the electronic device through the heat dissipation vent, avoid opening windows on the body assembly, thus preserving the integrity of the body assembly and improving the sophistication of the electronic device's design.

[0019] In some embodiments, the first surface includes a radiation zone and an air outlet zone, the air outlet is located in the air outlet zone, the radiation zone surrounds the air outlet zone, and a first radiator is disposed in the radiation zone.

[0020] By implementing the above settings, the proportion of the radiation zone occupying the central area of ​​the heat dissipation vent can be reduced, making the airflow through the air outlet and vent smoother and improving the heat dissipation efficiency of electronic devices.

[0021] In some embodiments, the radiation zone includes a first radiation zone and a second radiation zone, wherein the first radiation zone and the air outlet zone are spaced apart in the height direction of the first main body, and the second radiation zone and the air outlet zone are spaced apart in the length direction of the first main body; a first radiator is disposed in the first radiation zone and the second radiation zone.

[0022] With the above settings, while ensuring that the radiation area occupies the central area of ​​the heat dissipation port, the first radiation area and the air outlet area are spaced apart in the height direction of the first main body (i.e., the first radiation area and the air outlet area do not overlap in the height direction of the first main body), and the second radiation area and the air outlet area are spaced apart in the length direction of the first main body (i.e., the second radiation area and the air outlet area do not overlap in the length direction of the first main body). First radiators can be set in both the first radiation area and the second radiation area, which increases the number of first radiators in the antenna and can improve the performance of the antenna.

[0023] In some embodiments, the antenna further includes a first cable, one end of which is electrically connected to a first radiator, and the other end of which is used to connect to a motherboard in an electronic device for transmitting radio frequency signals to the first radiator or transmitting radio frequency signals received by the first radiator to the motherboard.

[0024] In some embodiments, the antenna further includes a second body, a second radiator, and a second cable. The first body and the second body are spaced apart and arranged in a direction perpendicular to the arrangement direction of the first end and the second end. The second radiator is disposed on the second body, and the second cable is electrically connected to the second radiator.

[0025] With the above configuration, in addition to the first main body and the first radiator, the antenna also includes a second main body and a second radiator, which increases the number of radiators in the antenna and improves the antenna performance.

[0026] In some embodiments, the electronic device further includes an appearance component disposed at a heat dissipation vent and covering the first surface and the air outlet; the appearance component is provided with a plurality of heat dissipation sub-vents communicating with the air outlet and exposing the first surface.

[0027] With the above settings, the heat dissipation port can expose the first surface to enable the antenna to function normally. Furthermore, the connection between the heat dissipation port and the air outlet can also enable the heat dissipation function of the electronic device. At the same time, the exterior components can cover the antenna located inside the body components, improving the appearance and sophistication of the electronic device.

[0028] In some embodiments, the vertical distance from the first surface to the appearance component away from the antenna is 0 to 1 / 8 times the antenna operating frequency wavelength.

[0029] In the above embodiment, the vertical distance from the first surface to the outer appearance component away from the antenna can be 3mm.

[0030] With the above settings, the exterior components can cover the antenna located inside the body components, preventing the antenna inside the body components from being directly observed from the heat dissipation vents on the exterior components, thus affecting the aesthetics of the electronic device.

[0031] This application embodiment also provides an electronic device that may further include a motherboard and an input / output interface. The motherboard is located within the chassis assembly, and the input / output interface is located on the side of the motherboard near a first end, extending through the first end and spaced apart from the antenna. The input / output interface is electrically connected to the motherboard. Other connectors (such as USB (Universal Serial Bus) connectors, HDMI (High Definition Multimedia Interface) connectors, etc.) can be electrically connected to the motherboard in the electronic device through the input / output interface, thereby enabling data transmission.

[0032] In some embodiments, the input / output interface may include a USB-A interface, which may include a USB-A housing located on the side of the motherboard near the first end. The USB-A housing has an opening facing the first end, extending through the first end. In embodiments where the housing assembly includes a second housing, the opening of the USB-A housing extends through the second housing, and this opening is used for inserting a USB-A connector. The USB-A interface may also include a first support member disposed at the end of the USB-A housing opposite to the opening, for limiting the depth of insertion of the USB-A connector into the USB-A interface. The USB-A interface may also include a second support member located inside the USB-A housing, and the extension of the second support member... The extension direction is perpendicular to and connected to the extension direction of the first support member. The second support member is provided with wiring for electrical connection to the motherboard. The second support member can guide the USB-A connector during the insertion of the USB-A connector into the USB-A interface. The internal dimensions of the USB-A shell are slightly larger than the external dimensions of the USB-A shell, so that after the USB-A connector is inserted into the USB-A interface, the gap between the USB-A connector and the USB-A interface is less than 0.5mm. Combined with the first support member limiting the depth of the USB-A connector inserted into the USB-A interface, the contact points on the USB-A connector can make contact with the wiring on the second support member, thereby enabling the USB-A connector to realize data transmission with the motherboard through the USB-A interface.

[0033] In some embodiments, the USB-A interface further includes pins disposed outside the USB-A housing, one end of which is connected to a first support member, and wiring is electrically connected to the motherboard through the pins.

[0034] With the above settings, the projection of the pin and the projection of the first support overlap in the Z direction, thereby reducing the size of the USB-A interface in the Y direction. This can reduce the size of the electronic device in the Y direction and improve the appearance and refinement of the electronic device.

[0035] This application embodiment also provides an electronic device that may further include a screen assembly and a hinge. The screen assembly is located on one side of the body assembly, and the screen assembly is connected to the body assembly via the hinge. The hinge is disposed near the first end and is located on the side of the body assembly near the screen assembly.

[0036] The hinge includes a core, a first component, and a second component. The outer edges of both the first and second components in their cross-sections perpendicular to the core axis are arc-shaped. The relative positions of the first and second components are fixed. The first component is connected to the screen assembly and is closer to the core axis than the second component. A channel is formed between the first and second components to accommodate a circuit board connecting the screen assembly and the body assembly. The core is connected to the first component and is configured to allow the screen assembly to rotate relative to the body assembly. In daily use of the electronic device, the user opens the screen assembly and body assembly, which are close together. The screen assembly causes the first and second components to rotate out around the core, exposing at least part of the first and second components. The first and second components protect the flexible circuit board located between them. Conversely, the user brings the opened screen assembly and body assembly closer together, causing the screen assembly to rotate the first and second components back in around the core. This achieves the opening and closing of the electronic device.

[0037] In some embodiments, the distance from the axis of the shaft to the arc of the second component is greater than 7 mm and less than 9 mm.

[0038] By reducing the distance between the axis of the shaft core and the arc of the second component, the space used by the body assembly to accommodate the first and second components can be reduced, thereby reducing the size of the body assembly, which in turn reduces the size of the electronic device and improves the appearance and sophistication of the electronic device.

[0039] In some embodiments, the hinge further includes a connector and a limiting member. The shaft core is connected to the first component via the connector, and the limiting member has a limiting plane. When the electronic device is in the closed state, the angle between the extension direction of the connector and the limiting plane is greater than 120° and less than 125°. With the above configuration, the size of the hinge can be reduced, thereby reducing the size of the second body assembly used to house the hinge in the Y direction, reducing the size of the electronic device in the Y direction, and improving the aesthetic appeal of the electronic device.

[0040] In some embodiments, the arc of the first component includes a first arc and a second arc connected together, the first arc being closer to the screen component than the second arc, the center of the first arc being located on the axis of the core, the distance of the second arc to the axis of the core being less than the radius of the first arc, and the distance of the second arc to the axis of the core gradually decreasing in a direction away from the first arc.

[0041] With the above configuration, a portion of the flexible circuit board is fixed to the first component. The distance from the second arc to the axis of the shaft core is less than the radius of the first arc, which increases the bending radius of the flexible circuit board fixed on the second arc. In embodiments where the radius of the second arc is equal to the radius of the first arc, the distance from the second arc to the axis of the shaft core is less than the radius of the first arc. This causes the portion of the flexible circuit board that bends along the second arc away from the first arc to be closer to the axis of the shaft core, thereby reducing the space occupied by the flexible circuit board in the body assembly. This, in turn, reduces the size of the body assembly, thereby reducing the size of the electronic device and improving the appearance and refinement of the electronic device.

[0062] For ease of description, the following defines the direction parallel to the pivot axis (i.e., the axis of the shaft core) of the rotating shaft 170 as the X direction, the direction parallel to the main plane of the fuselage assembly 120 (i.e., the surface with the largest area of ​​the fuselage assembly 120) and perpendicular to the X direction as the Y direction, and the direction perpendicular to the main plane of the fuselage assembly 120 and perpendicular to the X direction as the Z direction.

The back surface of the display screen 112 is housed in a first receiving space and is not visible to the user.

[0068] As shown in Figure 1, the fuselage assembly 120 includes a second housing 121. The second housing 121 forms a second receiving space for accommodating electronic devices disposed on one side of the fuselage assembly 120. The second housing 121 can also protect the electronic device 100 and increase the heat dissipation of the electronic device 100.

[0069] The second housing 121 can be made of a metallic material, such as aluminum alloy, magnesium alloy, aluminum-magnesium alloy, titanium alloy, austenitic stainless steel, etc.; or, the second housing 121 can be made of a non-metallic material, such as carbon fiber, polycarbonate (PC), engineering plastics, glass, ceramics, wood, leather, sapphire, composite materials, etc. The second housing 121 and the first housing 111 can be made of the same or different materials, and this application embodiment does not limit this.

[0072] Please refer to Figures 2 and 3. Figure 2 is a cross-sectional view formed along the YZ plane in Figure 1; Figure 3 is a schematic view of Figure 2 viewed along the Y direction, wherein in Figure 3(a), the exterior component 142 is removed, and in Figure 3(b), the exterior component 142 is retained. In the embodiment of this application, in the embodiment where the fuselage component 120 includes a second housing 121 and a cooling fan 122, the cooling fan 122 is housed inside the second housing 121. The second housing 121 has a first end 10 and a second end 20 that are arranged opposite to each other, that is, the first end 10 and the second end 20 are arranged opposite to each other along the Y direction, wherein the first end 10 is provided with a heat dissipation vent 123, and the air outlet direction of the cooling fan 122 points towards the heat dissipation vent 123.

[0073] Referring again to Figures 2 and 3, in an embodiment where the fuselage assembly 120 includes a second housing 121 and an antenna 124, the antenna 124 is also housed inside the second housing 121. The antenna 124 includes a first body 125 and a first radiator 30. The first body 125 is located inside the fuselage assembly 120 and is disposed near the first end 10. In an embodiment where a cooling fan 122 is housed inside the second housing 121, the first body 125 is located between the cooling fan 122 and the heat dissipation vent 123. The first body 125 includes a first surface 126 facing the heat dissipation vent 123, and the first radiator 30 is disposed on the first surface 126 for transmitting or receiving electromagnetic wave signals to realize the performance of the antenna 124.

[0074] Referring to Figure 4 in conjunction with Figure 2, Figure 4 is a structural schematic diagram of one embodiment of the antenna 124 in this application. The first main body 125 is provided with an air outlet channel 127. Multiple air outlet channels 127 can be provided, and the multiple air outlet channels 127 are spaced apart along the length direction of the first main body (i.e., the multiple air outlet channels 127 are spaced apart along the X direction). The extension direction of each air outlet channel 127 is the same as the air outlet direction of the cooling fan 122. The air outlet channel 127 penetrates the first surface 126 and forms an air outlet 128 on the first surface 126. The air outlet 128 is connected to the heat dissipation port 123. That is to say, the air outlet channel 127 connects the heat dissipation port 123 of the second housing 121 with the cooling fan 122 located inside the second housing 121.

[0075] In the above embodiments, the first radiator 30 is disposed on the first surface 126, including forming the first radiator 30 on the first surface 126; for example, the first radiator 30 may include an LDS antenna 124 formed by laser direct forming (LDS) process, and the first body 125 includes an injection-molded plastic part, using laser technology to directly engrave a three-dimensional circuit pattern on the first surface 126, and then electroplating to form a three-dimensional metal circuit to form the LDS antenna 124.

[0076] In the above embodiments, the first radiator 30 is disposed on the first surface 126, and the first radiator 30 is also disposed on the first surface 126. For example, the first radiator 30 may include a patch antenna 124, which is directly attached to the first surface 126 of the first body 125.

[0077] In the above embodiments, the antenna 124 may functionally include a cellular antenna, a WiFi antenna, a Bluetooth antenna, etc., and structurally include a monopole antenna, a dipole antenna, etc.

[0078] Referring to Figures 2 and 4, this application provides an electronic device 100. A body assembly 120 has a heat dissipation vent 123. An antenna 124 includes a first body 125 and a first radiator 30. The first body 125 is located inside the body assembly 120 and has multiple spaced air outlet channels 127. One end of each air outlet channel 127 penetrates a first surface 126 to form an air outlet 128 on the first surface 126. The air outlet 128 communicates with the heat dissipation vent 123. The other end of the air outlet channel 127 is used to connect to a cooling fan 122. During the heat dissipation process of the electronic device 100, the cooling fan 122 drives… The airflow passes through the air outlet 127 and the air outlet 128, and is discharged from the heat dissipation port 123 to dissipate heat from the electronic device 100. The first radiator 30 is disposed on the first surface 126 of the first body 125 facing the heat dissipation port 123, so that the first radiator 30 can transmit or receive electromagnetic wave signals through the heat dissipation port 123. This can achieve the performance of the antenna 124 without affecting the heat dissipation of the electronic device 100 through the heat dissipation port 123, avoid opening windows on the all-metal electronic device 100, damage the integrity of the body component 120, and improve the refinement of the ID of the electronic device 100.

[0079] In the embodiment where the first body 125 is located between the cooling fan 122 and the heat dissipation port 123, the electronic device 100 further includes a heat dissipation fin 129 and a heat dissipation pipe 130. The heat dissipation fin 129 and the heat dissipation pipe 130 are disposed between the first body 125 and the cooling fan 122. The heat dissipation fin 129 and the heat dissipation pipe 130 are arranged adjacent to each other. An air duct is formed inside the heat dissipation fin 129. The air duct is connected to the air outlet channel 127 on the first body 125. The heat dissipation pipe 130 transfers the heat generated by the electronic device 100 to the heat dissipation fin 129. The cooling fan 122 drives the air through the air duct of the heat dissipation fin 129, then through the air outlet channel 127 and the air outlet 128, and is discharged from the electronic device 100 from the heat dissipation port 123. The heat dissipation fin 129 and the heat dissipation pipe 130 can improve the heat dissipation efficiency of the electronic device 100.

[0080] Referring to Figures 4 and 5, in the above embodiment, the first surface 126 includes a radiation area and an air outlet area 132. The air outlet 128 is located in the air outlet area 132, and the radiation area is arranged around the air outlet area 132. That is, on the first surface 126, the radiation area avoids the air outlet area 132, so as to avoid the radiation area occupying the proportion of the central area of ​​the heat dissipation port 123 (as shown in Figure 3), reduce the proportion of the first radiation area 131 occupying the central area of ​​the heat dissipation port 123 (as shown in Figure 3), make the airflow through the air outlet channel 127 and the air outlet 128 smoother, and improve the heat dissipation efficiency of the electronic device 100.

[0081] For example, the radiation area may include a first radiation area 131 and a second radiation area 133. The first radiation area 131 and the air outlet area 132 are spaced apart in the height direction of the first main body 125, that is, the first radiation area 131 and the air outlet area 132 are spaced apart in the Z direction (the first radiation area and the air outlet area do not coincide in the height direction of the first main body); wherein the first radiation area 131 is located above the air outlet area 132. That is, in the embodiment where the electronic device 100 includes a screen assembly 110 (as shown in FIG. 1) and a body assembly 120 (as shown in FIG. 1), the first radiation area 131 is closer to the screen assembly 110 than the air outlet area 132. In the embodiment where the antenna 124 includes a first radiator 30, the first radiator 30 is disposed in the first radiation area 131.

[0082] The second radiation zone 133 and the air outlet zone 132 are spaced apart along the length of the first main body 125, that is, the second radiation zone 133 and the air outlet zone 132 are spaced apart in the X direction (the second radiation zone and the air outlet zone do not coincide along the length of the first main body); the first radiator 30 is also disposed in the second radiation zone 133. With the above arrangement, under the premise that the air outlet 128 is sufficient to meet the heat dissipation requirements, the addition of the second radiation zone 133 on one side of the air outlet 128, and the first radiator 30 can also be disposed in the second radiation zone 133, increases the number of first radiators 30 in the antenna 124, which can improve the performance of the antenna 124.

[0083] Referring to Figure 5, in this embodiment of the application, the first radiation zone 131 is located above the air outlet zone 132, and the second radiation zone 133 is located to the right of the air outlet zone 132. It can be understood that the first radiation zone 131 may also be located below the air outlet zone 132, and the second radiation zone 133 may also be located to the left of the air outlet zone 132.

[0084] Referring again to FIG4, in an embodiment in which the electronic devices housed in the second housing 121 (as shown in FIG1) include a motherboard, the antenna 124 may further include a first cable 134, one end of the first cable 134 being electrically connected to the first radiator 30, and the other end of the first cable 134 being connected to the motherboard for transmitting radio frequency signals to the first radiator 30, or transmitting radio frequency signals received by the first radiator 30 to the motherboard.

[0085] In the above embodiments, the first body 125 of the antenna 124 also includes a second surface 135 adjacent to the first surface 126. In some embodiments, the first surface 126 is parallel to the XZ plane, and the second surface 135 may be a surface on the first body 125 that is parallel to the XY plane. Referring to Figures 4 and 5, for example, if the second surface 135 is located on the side of the air outlet area 132 away from the first radiation area 131, then in the embodiment where the electronic device 100 includes a screen assembly 110 (as shown in Figure 1) and a body assembly 120 (as shown in Figure 1), the second surface 135 is connected to the edge of the first surface 126 away from the screen assembly 110. Alternatively, if the second surface 135 is located on the side of the first radiation area 131 away from the air outlet area 132, then in the embodiment where the electronic device 100 includes a screen assembly 110 and a body assembly 120, the second surface 135 is connected to the edge of the first surface 126 near the screen assembly 110. Antenna 124 may also include a Mylar sheet 136 covering the second surface 135. In an embodiment where the first cable 134 can be disposed on the second surface 135, the Mylar sheet 136 can cover the first cable 134 to protect the first cable 134.

[0086] In the above embodiments, the antenna 124 may also include conductive foam 137, which can also cover the second surface 135 to achieve electrostatic protection for the antenna 124 and to act as a buffer between the antenna 124 and the second housing 121 when the antenna 124 is installed on the second housing 121.

[0087] Please refer to Figure 6, which is a cross-sectional view formed along the XY plane in Figure 1. In the electronic device 100, the cooling fan 122 may include a first cooling fan 138 and a second cooling fan 139. Both the first cooling fan 138 and the second cooling fan 139 are disposed within the second housing 121, and their airflow directions are the same. The first cooling fan 138 and the second cooling fan 139 are spaced apart along the X direction. It is understood that increasing the number of cooling fans 122 can improve the heat dissipation efficiency of the electronic device 100.

[0088] Referring to Figures 6 and 7, in the above embodiments, the antenna 124 may further include a second body 140, which is also located within the body assembly 120 and is also disposed close to the first end 10. In the embodiment where the cooling fan 122 is housed within the second housing 121, the second body 140 is also located between the cooling fan 122 and the heat dissipation port 123. The antenna 124 also includes a second radiator, which is disposed on the surface of the second body 140 facing the heat dissipation port 123 and is used to transmit or receive electromagnetic wave signals to realize the performance of the antenna 124. The second body 140 is also provided with a plurality of spaced air outlet channels 127, and the extension direction of each air outlet channel 127 is the same as the air outlet direction of the cooling fan 122. In an embodiment where the cooling fan 122 includes a first cooling fan 138 and a second cooling fan 139, the first body 125 of the antenna 124 can correspond to the first cooling fan 138, that is, the air outlet channel 127 formed on the first body 125 connects the heat dissipation port 123 of the electronic device 100 and the first cooling fan 138; the second body 140 of the antenna 124 can correspond to the second cooling fan 139, that is, the air outlet channel 127 formed on the second body 140 connects the heat dissipation port 123 of the electronic device 100 and the second cooling fan 139. The first body 125 and the second body 140 are spaced apart along the X direction. For example, the arrangement direction of the first body 125 and the second body 140 is perpendicular to the arrangement direction of the first end 10 and the second end 20. Through the above arrangement, based on the antenna 124 including the first body 125 and the first radiator 30, the antenna 124 also includes the second body 140 and the second radiator, increasing the number of radiators in the antenna 124 and improving the performance of the antenna 124.

[0089] In the above embodiments, the second radiator being disposed on the second body 140 includes forming the second radiator on the second body 140 by an LDS process; it may also include placing the patch antenna 124 on the second body 140; similar to the embodiment in which the first radiator 30 is disposed on the first surface 126 of the first body 125, it will not be described in detail here.

[0090] In the above embodiments, the antenna 124 further includes a second cable 141. One end of the second cable 141 is electrically connected to the second radiator, and the other end of the second cable 141 is used to connect to the motherboard in the electronic device 100 for transmitting radio frequency signals to the second radiator or transmitting radio frequency signals received by the second radiator to the motherboard. In embodiments where the antenna 124 includes a first cable 134 and a second cable 141, the first cable 134 is connected to the first radiator 30 and the second cable 141, and the second cable 141 is connected to the second radiator and the first cable 134, and the first cable 134 and the second cable 141 are connected together to the motherboard of the electronic device 100; wherein the first cable 134 and the second cable 141 are electrically connected by a snap-fit ​​mechanism.

[0091] In the above embodiments, the Mylar sheet 136 and the conductive foam 137 can also be disposed on the second body 140, and their connection relationship and positional relationship with the second body are the same as those of the first body 125, which will not be described in detail here.

[0092] Referring to Figures 3 and 4, in some embodiments, the electronic device 100 further includes an appearance component 142. The appearance component 142 is disposed at the heat dissipation vent 123 and covers the first surface 126 and the air outlet 128. The appearance component 142 is provided with a plurality of heat dissipation sub-vents 143, which are connected to the air outlet 128 and expose the first surface 126. Through the above arrangement, the heat dissipation sub-vents 143 can expose the first surface 126 to realize the normal function of the antenna 124. Furthermore, the connection between the heat dissipation sub-vents 143 and the air outlet 128 can also realize the heat dissipation function of the electronic device 100. At the same time, the appearance component 142 can cover the antenna 124 located inside the body component 120, improving the appearance and refinement of the electronic device 100.

[0093] In the above embodiment, the appearance component 142 includes a first fixing member 144, a second fixing member 145, and a heat sink 146. The heat sink 146 extends along the X direction and has a plurality of heat dissipation outlets 143 spaced apart along the X direction. The first fixing member 144 is located at one end of the heat sink 146 along the X direction, and the second fixing member 145 is located at the other end of the heat sink 146 along the X direction. The heat sink 146 and the first fixing member 144 can be connected by snap-fit, and the heat sink 146 and the second fixing member 145 can also be connected by snap-fit. The first fixing member 144 and the second fixing member 145 are used to connect to the second housing 121 in the body component 120. For example, the first fixing member 144 and the second fixing member 145 can be integrally formed with the second housing 121 by stamping; or both the first fixing member 144 and the second fixing member 145 can be bonded to the second housing 121.

[0094] In the above embodiment, the heat sink 146 includes a first heat sink 147 and a second heat sink 148. Both the first heat sink 147 and the second heat sink 148 extend along the X direction and are spaced apart along the X direction. Both the first heat sink 147 and the second heat sink 148 are provided with heat dissipation ports 143. The first heat sink 147 can cover the first body 125 of the antenna 124, and the second heat sink 148 can cover the second body 140 of the antenna 124.

[0095] The appearance assembly 142 also includes a third fastener 149, which is located in the X direction between the first heat sink 147 and the second heat sink 148. The end of the first heat sink 147 near the third fastener 149 can be connected to the third fastener 149 via a snap-fit ​​connection, and the end of the second heat sink 148 near the third fastener 149 can also be connected to the third fastener 149 via a snap-fit ​​connection. In embodiments where the appearance assembly 142 includes a first fastener 144 and a second fastener 145, the end of the first heat sink 147 away from the third fastener 149 is connected to the first fastener 144, and the end of the second heat sink 148 away from the third fastener 149 is connected to the second fastener 145. The third fastener 149 can also be used to connect to the second housing 121 in the body assembly 120. For example, the third fastener 149 can be an integral structure with the second housing 121, formed by stamping; or the third fastener 149 can be bonded to the second housing 121. Compared to the appearance component 142, which includes a first fastener 144 and a second fastener 145, the third fastener 149 can increase the connection strength between the appearance component 142 and the second housing 121, and improve the stability of the assembly of the appearance component 142 and the body component 120.

[0096] Referring to Figure 6, in some embodiments, the vertical distance from the first surface 126 of the first body 125 or the first surface 126 of the second body 140 to the appearance component 142 in the antenna 124 is 0 to 1 / 8 times the antenna operating frequency wavelength. For example, when the operating frequency of the antenna 124 is 2.4 GHz, the antenna operating frequency wavelength is 125 mm; when the operating frequency of the antenna 124 is 5 GHz, the antenna operating frequency wavelength is 94 mm. Specifically, the vertical distance from the first surface 126 of the first body 125 or the first surface 126 of the second body 140 to the appearance component 142 in the antenna 124 may include 1 mm, 1.5 mm, 2 mm, 2.5 mm, 3 mm, 3.5 mm, 4 mm, 4.5 mm, 5 mm, etc.

[0097] With the above settings, the appearance component 142 can cover the antenna 124 located inside the body component 120, preventing the antenna 124 located inside the body component 120 from being directly observed from the heat dissipation port 143 on the appearance component 142, thereby affecting the appearance and refinement of the electronic device 100.

[0098] Referring to Figures 3 and 6, in some embodiments, the electronic device 100 further includes an input / output interface 150. The input / output interface 150 is disposed at the first end 10 of the chassis assembly 120. In embodiments where the electronic device 100 includes a motherboard, the input / output interface 150 is located on the side of the motherboard near the first end 10, extends through the first end 10, and is spaced apart from the antenna 124. In embodiments where the exterior assembly 142 includes a third fixing member 149, the input / output interface 150 is disposed on the third fixing member 149, wherein one end of the input / output interface 150 extends through the third fixing member 149, and the other end of the input / output interface 150 extends toward the motherboard and is electrically connected to the motherboard. This allows other connectors (e.g., USB connectors, HDMI connectors, etc.) to be electrically connected to the motherboard in the electronic device 100 through the input / output interface 150, thereby enabling data transmission. It should be noted that this embodiment can be based on an embodiment where the electronic device 100 includes the antenna 124, or on an embodiment where the electronic device 100 only includes the chassis assembly 120 and the input / output interface 150.

[0099] Referring to Figures 3 and 8, in the above embodiments, the input / output interface 150 may include a USB-A interface 151, and the USB-A interface 151 may include a USB-A housing 152. The USB-A housing 152 is located on the side of the motherboard near the first end 10, and the USB-A housing 152 has an opening facing the first end 10, which penetrates the first end 10. In embodiments where the chassis assembly 120 includes a second housing 121, the opening of the USB-A housing 152 penetrates the second housing 121, and the opening is used to allow the USB-A connector to be inserted. The USB-A interface 151 may further include a first support member 153, which is disposed at one end of the USB-A housing 152 away from the opening, and is used to limit the depth of the USB-A connector inserted into the USB-A interface 151. The USB-A interface 151 also includes a second support member 154, which is located inside the USB-A housing 152, and the extension direction of the second support member 154 is perpendicular to the extension direction of the first support member 153 and connected to the first support member 153. The second support member 154 is provided with wiring for electrical connection to the motherboard. The second support member 154 allows the USB-A connector to be inserted into the USB-A interface. The USB-A interface 151 acts as a guide during the process, while the internal dimensions of the USB-A housing 152 are slightly larger than the external dimensions of the USB-A housing 152. This ensures that after the USB-A connector is inserted into the USB-A interface 151, the distance between the USB-A connector and the USB-A interface 151 is less than 0.5mm. In conjunction with the first support member 153, which restricts the depth of the USB-A connector insertion into the USB-A interface 151, the contact points on the USB-A connector can make contact with the wiring on the second support member 154. This allows the USB-A connector to transmit data with the motherboard through the USB-A interface 151.

[0100] Referring again to Figures 3 and 8, in some embodiments, the electronic device 100 includes a USB-A interface 151 and an HDMI interface 155 (as shown in Figure 6). The USB-A interface 151 has a Y-direction dimension of 14.4 mm, and the HDMI interface 155 has a Y-direction dimension of 2.42 mm to 4.45 mm (for example, the HDMI specification specifies four types of HDMI interfaces 155, where the HDMI A Type has a dimension of 4.45 mm, the HDMI B Type has a dimension of 4.45 mm, the HDMI C Type has a dimension of 2.42 mm, and the HDMI D Type has a dimension of 2.8 mm). By comparison, it can be seen that the Y-direction dimension of the HDMI interface 155 is smaller than that of the USB-A interface 151.

[0101] Referring again to Figures 3 and 8, in Figure 8, the USB-A plug is inserted into the USB-A interface 151 in the direction of arrow J. In one embodiment of this application, the USB-A interface 151 includes pins 156, which are disposed outside the USB-A housing 152 and located at one end of the first support member 153. The wiring on the second support member 154 is electrically connected to the motherboard 166 through pins 156. With the above arrangement, the projection of pins 156 and the projection of the first support member 153 overlap in the Z direction, thereby reducing the size of the USB-A interface 151 in the Y direction. For example, the USB-A interface 151 has a size of 11.1 mm in the Y direction. By comparison, it can be seen that the size of the HDMI interface 155 in the Y direction is less than 11.1 mm. Therefore, in the embodiment where the electronic device 100 includes the HDMI interface 155 and the USB-A interface 151, the size of the USB-A interface 151 in the Y direction is reduced. However, the reduced size is still larger than the size of the HDMI interface 155 in the Y direction. Therefore, reducing the size of the USB-A interface 151 in the Y direction alone can reduce the size of the electronic device 100 in the Y direction and improve the appearance and refinement of the electronic device 100.

[0102] In the above embodiments, the first support 153 and the second support 154 may include plastic material. After reducing the size of the USB-A interface 151 in the Y direction, a plastic mechanics simulation was performed on the plastic parts in the USB-A interface 151. The maximum cracking stress obtained was 105.5 MPa, which is greater than the predetermined maximum cracking stress of 100.5 MPa. This proves that the USB-A interface 151 still meets the usage standards after reducing the size in the Y direction.

[0103] In the above embodiments, the USB-A casing 152 may include a metallic material, such as iron. After reducing the size of the USB-A interface 151 in the Y direction, a mechanical simulation of the USB-A casing 152 in the USB-A interface 151 was performed. The obtained deformation stress boundary was 780 MPa, which is greater than the predetermined deformation stress boundary of 770.5 MPa. This proves that the USB-A interface 151 still meets the usage standards after reducing the size in the Y direction.

[0104] Referring to Figure 6, in some embodiments, the body assembly 120 includes a first body assembly 157 and a second body assembly 158. The first body assembly 157 is larger in the Y direction than the second body assembly 158. The first body assembly 157 and the second body assembly 158 can be fixedly connected or are an integral structure (the first body assembly 157 and the second body assembly 158 are distinguished by dashed lines in Figure 6). In embodiments where the electronic device 100 includes a screen assembly 110, a body assembly 120, and a hinge 170, the hinge 170 for connecting the screen assembly 110 and the body assembly 120 is located at the boundary between the first body assembly 157 and the second body assembly 158. When the electronic device 100 is in a closed state, the screen assembly 110 is in contact with the first body assembly 157. In conjunction with the above embodiments, since the USB-A interface 151 and HDMI interface 155 are disposed within the second body assembly 158, reducing the size of the USB-A interface 151 in the Y direction can reduce the size of the second body assembly 158 in the Y direction, thereby improving the aesthetic appeal of the electronic device 100. In some embodiments, the second body assembly 158 may be referred to as a tail fin.

[0105] Referring to Figures 9 and 10, in an embodiment where the electronic device 100 includes a screen assembly 110 and a hinge 170, the screen assembly 110 is located on one side of the body assembly 120, and the screen assembly 110 is connected to the body assembly 120 via the hinge 170. The hinge 170 is disposed near the first end 10 and is located on the side of the body assembly 120 near the screen assembly 110. The hinge 170 includes a shaft core 159, a first component 160, and a second component 161. The outer edges of the first component 160 and the second component 161 in the cross-section perpendicular to the axis of the shaft core 159 are both arc-shaped. When the electronic device 100 is in the closed state, the apex of the arc of the first component 160 and the second component 161 faces the side away from the screen assembly 110. The relative positions of the first component 160 and the second component 161 are fixed, and the first component 160 is connected to the screen assembly 110. The first component 160 is closer to the axis of the shaft core 159 relative to the second component 161. A channel is formed between the first component 160 and the second component 161 to accommodate a circuit board that connects the screen assembly 110 and the body assembly 120. The circuit board may include a flexible circuit board 162, which is fixed on the arc of the first component 160 facing the second component 161. The shaft core 159 is connected to the first component 160 and is configured to allow the screen assembly 110 to rotate relative to the body assembly 120. In daily use of the electronic device 100, the user opens the screen assembly 110 and the body assembly 120, which are close together. The screen assembly 110 causes the first component 160 and the second component 161 to rotate out around the axis 159. At this time, at least part of the first component 160 and the second component 161 are exposed, and the first component and the second component 161 can protect the flexible circuit board 162 located between the first component 160 and the second component 161. When the user brings the opened screen assembly 110 and the body assembly 120 close together, the screen assembly 110 causes the first component 160 and the second component 161 to rotate in around the axis 159. In this way, the opening and closing of the electronic device 100 is realized. It should be noted that the embodiment of the electronic device 100 including the screen assembly 110 and the hinge 170 can be based on the embodiment of the electronic device 100 including the antenna 124, or it can be based on the embodiment of the electronic device 100 including only the body assembly 120.

[0106] In the above embodiments, the distance from the axis of the shaft core 159 to the arc of the second component 161 can be reduced. For example, the distance from the axis of the shaft core 159 to the arc of the second component 161 is greater than 7mm and less than 9mm. It is understood that, in the closed state of the electronic device 100, in conjunction with the above description of the second body assembly 158, at least a portion of the first component 160 and at least a portion of the second component 161 are located within the second body assembly 158. Therefore, reducing the distance from the axis of the shaft core 159 to the arc of the second component 161 can reduce the space in the second body assembly 158 used to accommodate the first component 160 and the second component 161, thereby reducing the size of the second body assembly 158 in the Y direction, and thus reducing the size of the electronic device 100 in the Y direction, improving the appearance and refinement of the electronic device 100.

[0107] In some embodiments, when the electronic device 100 is in the open state, especially when the opening angle between the screen assembly 110 and the body assembly 120 is greater than 90°, at least part of the screen assembly 110 will be located on the side of the body assembly 120 away from the second end 20. Since the antenna 124 is located at the first end 10 opposite to the second end 20 of the body assembly 120, in embodiments where the first housing 111 of the screen assembly 110 is made of metal, the first housing 111 made of metal will affect the performance of the antenna 124 (e.g., reduce the radiation distance and radiation intensity of the antenna 124). Therefore, the second body assembly 158 needs to maintain a certain size in the Y direction to reduce the influence of the metal of the screen assembly 110 on the antenna 124. Therefore, in this embodiment, the rotating shaft 170 also includes a connector 163 and a limiting member 164. The shaft core 159 is connected to the first component 160 through the connector 163. The limiting member 164 is fixed on the side of the shaft core 159 away from the first end 10, and a limiting plane 165 is provided on the limiting member 164. When the electronic device 100 is in the closed state, the connector 163 is connected to the end of the first component 160 away from the second end 20. The angle between the extension direction of the connector 163 and the limiting plane 165 is greater than 120° and less than 125°. During the unfolding process of the electronic device 100, after the connector 163 is attached to the limiting plane 165, the limiting member 164 can prevent the connector 163 from continuing to rotate around the shaft core 159, thereby limiting the rotation of the first component 160 and the second component 161, thus limiting the unfolding angle of the screen assembly 110. Limiting the unfolding angle of the screen assembly 110 can reduce the size of the hinge 170, thereby reducing the size of the second body assembly 158 used to house the hinge 170 in the Y direction, reducing the size of the electronic device 100 in the Y direction, and improving the appearance and refinement of the electronic device 100.

[0108] In some embodiments, the center of the first arc is located on the arc of the first component 160, which includes a connected first arc L1 and a second arc L2. The first arc L1 is closer to the screen component 110 than the second arc L2. The center of the first arc L1 is located on the axis of the core 159. The distance R2 from the second arc L2 to the axis of the core 159 is less than the radius R1 of the first arc L1. The distance R2 from the second arc L2 to the axis of the core 159 gradually decreases along the direction away from the first arc L1.

[0109] One end of the flexible circuit board 162 is connected to the screen assembly 110. Then, along the direction away from the screen assembly 110, the flexible circuit board 162 is sequentially fixed to the first arc L1 and the second arc L2, and bends, before connecting to the motherboard 166 in the electronic device 100. During the opening and closing of the electronic device 100, it is understood that during the rotation of the first component 160 relative to the shaft core 159, the portion of the flexible circuit board 162 not fixed to the first component 160 will bend. The flexible circuit board 162 has a maximum bending radius. When the bending radius of the flexible circuit board 162 is greater than or equal to the minimum bending radius, the flexible circuit board 162 can bend normally. When the bending radius of the flexible circuit board 162 is less than the minimum bending radius, the flexible circuit board 162 is prone to creases or breakage. With the above configuration, a portion of the flexible circuit board 162 is fixed to the first component 160. The distance from the second arc L2 to the axis of the core 159 is less than the radius of the first arc L1, which increases the bending curvature of the flexible circuit board 162 fixed on the second arc L2, but it is still greater than the minimum bending radius of the flexible circuit board 162. In the embodiment where the distance R2 from the second arc L2 to the axis of the core 159 is equal to the radius R1 of the first arc L1, the distance from the second arc L2 to the axis of the core 159 is less than the radius R1 of the first arc L1. This will cause the portion of the flexible circuit board 162 that bends along the direction away from the first arc L1 of the second arc L2 to be closer to the axis of the core 159, thereby reducing the space occupied by the flexible circuit board 162 in the second body assembly 158, and thus reducing the size of the second body assembly 158 in the Y direction. This will reduce the size of the electronic device 100 in the Y direction and improve the appearance refinement of the electronic device 100.

[0110] In the above embodiments, the distance between the center of the second arc L2 and the axis of the shaft core 159 is set such that, in embodiments where the distance R2 from the second arc L2 to the axis of the shaft core 159 is less than the radius R1 of the first arc L1, the center of the second arc L2 is located on the side of the center of the first arc L1 away from the first end 10.
