Technical Field

[0002] The present application relates to the field of electronic technology, and in particular to electronic devices and terminal equipment. Background Art

[0003] Many electronic devices include an outer casing. This casing can be used to house, secure, install, and protect the various components within the device, while also providing aesthetic appeal and a variety of design options. However, if the outer casing is airtight and impermeable, the following risks arise: ① In long-term high-humidity environments, condensation can easily form and accumulate inside the device due to the diffusion of water molecules; ② The airtight design hinders the volatilization of organic molecules, exacerbating corrosion of internal components; ③ If there is a long-term pressure difference within the electronic device, or if a leak occurs at a weak point due to the breathing effect, negative pressure can cause water to be sucked back into the device. Therefore, it is important to design a breathable structure to maintain pressure balance inside and outside the electronic device.

[0004] Among some current ventilation design schemes, some keep the electronic device breathable by adding a waterproof breathable valve to the outer shell of the electronic device through snap fastening or threaded fastening. Some also form a breathable structure by providing breathable holes in the outer shell and then pasting a waterproof breathable membrane on the breathable holes. There are also methods that achieve a balance of internal and external ventilation by providing a hollow structure on the outer shell. However, some of these design schemes require the addition of an additional breathable valve or breathable membrane, which is complicated to install and increases the cost. Others use a hollow structure for ventilation. The hollow design is expensive and has a large air permeability. It is easy to introduce external water vapor into the interior of the electronic device to form more condensation beads. Therefore, how to reduce the introduction of external water vapor while achieving the ventilation function of the electronic device at a low cost is a technical problem that needs to be solved urgently. Summary of the Invention

[0005] The present application provides an electronic device and a terminal device, which can reduce the introduction of external water vapor while achieving the ventilation function of the electronic device at a low cost.

[0006] In a first aspect, the present application provides an electronic device comprising a first housing, an intermediate component, and a second housing; the first housing and the second housing are fixedly connected; the intermediate component is fixed in a cavity formed by the first housing and the second housing;

[0007] The first housing includes an outer surface and an inner surface, wherein the inner surface is a side surface facing the intermediate component, and the outer surface is a side surface opposite to the inner surface.

[0008] The outer surface of the first shell is provided with a first air permeable channel, the first shell is provided with a first through hole, the cavity is provided with a second air permeable channel, and the first through hole connects the first air permeable channel and the second air permeable channel.

[0009] Exemplarily, the aforementioned first shell and the aforementioned second shell can be fixedly connected by any of the following connection methods: threaded connection, snap connection, adhesive connection, ultrasonic connection, welding, hinged connection, or rivet connection, etc.

[0010] For example, the outer surface of the first shell may be provided with one or more first air permeable channels, and the cavity may be provided with one or more second air permeable channels, which can be selected according to the air permeability requirements.

[0011] In this solution, ventilation channels are provided on the outer surface of the electronic device housing and within the housing cavity. These channels are then connected via through-holes in the housing to achieve ventilation inside and outside the housing and maintain internal and external pressure balance. In this solution, the ventilation channels are formed directly into the housing, eliminating the need for additional ventilation valves or membranes. This also reduces the installation and inspection steps required for these valves and membranes, significantly saving costs. Furthermore, in this solution, gas flows through two ventilation channels and one through-hole, creating a long and winding path for gas flow. This ensures a controllable permeability and reduces the introduction of external moisture.

[0012] In a possible implementation, the second air permeable channel is angularly deflected relative to the first air permeable channel.

[0013] In this solution, the angular deflection between the inner and outer ventilation channels can increase the length and tortuosity of the gas flow path, reduce the air permeability, and further reduce the introduction of external water vapor.

[0014] In a possible implementation, if the first shell and the second shell are fixed by threaded connection, the first through hole is a through hole for allowing the threaded connection member to pass through.

[0015] In this solution, if the shell is fixed by threaded connection, the through hole of the threaded connection piece can be reused as a through hole connecting the inner and outer air passages, reducing the cost of setting up additional through holes.

[0016] In a possible implementation, the first air permeable channel extends beyond the area covered by the head of the threaded connector.

[0017] In this solution, the ventilation channel on the outer surface is designed to extend beyond the area covered by the head of the threaded connector, which can facilitate the flow of gas inside and outside. In addition, the increased length of the gas flow path can also keep the air permeability in a controllable state and reduce the introduction of external water vapor.

[0018] In one possible implementation, a threaded hole is provided on the inner surface of the second shell, and the threaded hole is used to cooperate with the threaded connecting piece to fasten the first shell and the second shell, and the inner surface of the second shell is a side surface facing the intermediate component; the second air vent is provided on the end face of the threaded hole.

[0019] In this solution, the internal air permeable channel is set on the end face of the threaded hole, which can extend the length and tortuosity of the path of gas flowing in and out, so that the gas turns and flows in the path, reducing the air permeability and thereby reducing the introduction of external water vapor.

[0020] In a possible implementation, the second air permeable channel is provided on the inner surface of the first shell.

[0021] In this solution, the internal air permeable channel is arranged on the inner surface of the shell provided with the external air permeable channel, so that the gas can pass through the first through hole and enter the interior.

[0022] In a possible implementation, the intermediate component includes a second through hole, and the threaded connector passes through the second through hole.

[0023] In this solution, the threaded connector for fixing the upper and lower shells also passes through the middle component to fix the middle component together, thereby enhancing the stability of the middle component.

[0024] In a possible implementation, the electronic device further includes a seal, which is disposed between the first shell and the second shell, with the first through hole in the middle of the seal, and the second air permeable channel extending beyond the coverage of the sealing ring.

[0025] In this solution, the airtightness of the electronic device can be increased by the sealing member. In this scenario, the length of the second air permeable channel can be extended beyond the range covered by the sealing member so as to maintain a controllable air permeability.

[0026] In a possible implementation, the cross-sections of the first air permeable channel and the second air permeable channel are rectangular, triangular, semicircular, or the like.

[0027] In this solution, the cross-sectional shape of the ventilation channel is not limited, which allows for flexibility and suitability for various scenarios.

[0028] In a possible implementation, the first air permeable channel and the second air permeable channel are straight channels or curved channels.

[0029] In this solution, the line shape of the ventilation channel is not limited, which allows for flexibility and suitability for various scenarios.

[0030] In one possible implementation, the electronic device further includes a cooling medium inlet and a third through hole, the cooling medium is used to dissipate heat for the electronic device, and no air passage connected to the third through hole is provided; the first through hole is closer to the cooling medium inlet than the third through hole.

[0031] In this solution, a ventilation channel is set near the cooling medium inlet. Because the temperature is lowest at this location and condensation beads are most likely to form, designing a ventilation channel here can quickly dissipate the condensation beads.

[0032] In one possible implementation, the electronic device further includes a moisture absorption module and a fourth through hole. The moisture absorption module is used to absorb moisture inside the electronic device, and no ventilation channel connected to the fourth through hole is provided. The first through hole is closer to the moisture absorption module than the fourth through hole.

[0033] In this solution, a ventilation channel is provided near the moisture absorption module. The ventilation channel can quickly evaporate the water vapor absorbed by the moisture absorption module.

[0034] In one possible implementation, the aforementioned electronic device is an autonomous driving controller, an intelligent cockpit domain controller, a vehicle controller, or a vehicle integrated unit in a vehicle.

[0035] In this solution, the electronic device can be various controllers in the vehicle or components including a housing. Optionally, the electronic device can also be various intelligent terminal devices, industrial equipment, or entertainment and leisure equipment including a housing.

[0036] In a second aspect, the present application provides a terminal device, which includes the electronic device as described in any one of the first aspects above.

[0037] For example, the terminal device may be a transportation tool such as a vehicle, a drone, a robot, etc. Of course, the terminal device may also be replaced by industrial equipment, entertainment and leisure equipment, etc. BRIEF DESCRIPTION OF THE DRAWINGS

[0049] In the embodiment of the present application, "multiple" refers to two or more. In the embodiment of the present application, "and / or" is used to describe the association relationship of associated objects, indicating three relationships that can exist independently. For example, A and / or B can be expressed as follows: A exists alone, B exists alone, or A and B exist at the same time. The description methods such as "at least one of a1, a2, ... and an" used in the embodiment of the present application include the situation where any one of a1, a2, ... and an exists alone, and also include any combination of any multiple of a1, a2, ... and an, each of which can exist alone; for example, the description method of "at least one of a, b and c" includes the situation where a is alone, b is alone, c is alone, a and b combination, a and c combination, b and c combination, or abc combination.

[0050] In this application, the terms "first," "second," and the like are used to distinguish between identical or similar items having substantially the same function or effect. It should be understood that "first," "second," and "nth" do not have a logical or temporal dependency, nor do they limit the quantity or order of execution. It should also be understood that although the following description uses the terms "first," "second," and the like to describe various elements, these elements should not be limited by these terms. These terms are simply used to distinguish one element from another.

[0051] In the various embodiments of the present application, unless otherwise specified or there is a logical conflict, the terms and / or descriptions between the various embodiments are consistent and can be referenced by each other. The technical features in different embodiments can be combined to form new embodiments according to their inherent logical relationships.

[0052] In order to achieve the ventilation function of an electronic device at a low cost while reducing the introduction of external water vapor, an embodiment of the present application provides an electronic device. The electronic device includes a first shell, an intermediate component, and a second shell. The first shell and the second shell are fixedly connected. The intermediate component is fixed in the cavity formed by the first shell and the second shell. The first shell includes an outer surface and an inner surface, the inner surface is a side surface facing the cavity, and the outer surface is the other side surface opposite to the direction of the inner surface. A first ventilation channel is provided on the outer surface of the first shell. And a first through hole is provided on the first shell. In addition, a second ventilation channel is provided in the cavity formed by the first shell and the second shell. The first through hole can connect the first ventilation channel and the second ventilation channel. An exemplary description is given below with reference to the accompanying drawings.

[0053] For example, please refer to Figure 1, which shows a schematic diagram of the appearance of an electronic device 100 provided in an embodiment of the present application. It can be seen that the electronic device 100 may include a first shell 110 and a second shell 120. The first shell 110 and the second shell 120 are fixedly connected. For example, the first shell 110 and the second shell 120 can be fixedly connected by any of the following connection methods: threaded connection, snap connection, adhesive connection, ultrasonic connection, welding, hinged connection, or rivet connection, etc. Among them, threaded connection refers to a detachable connection in which the connected parts are connected into one body with a threaded connection. Commonly used threaded connection parts include bolts, studs, screws, etc. It can be understood that the description of the connection method here is only an example and does not constitute a limitation to the embodiments of the present application.

[0054] Exemplarily, the electronic device 100 may be, for example, an on-board module device, an intelligent terminal device, an industrial device, or an entertainment and leisure device, etc. The on-board module device includes, but is not limited to, a mobile data center (MDC) device (e.g., also known as an autonomous driving controller), an intelligent cockpit domain controller (CDC), a vehicle control unit (VCU), a vehicle integrated / integration unit (VIU), or a telematics box (T-BOX), etc. The intelligent terminal device includes, but is not limited to, a mobile phone, a tablet computer, a laptop computer, a smart bracelet, a smart watch, or smart glasses, etc. The industrial device includes, but is not limited to, an industrial robot or a robotic arm, etc. The entertainment and leisure device includes, but is not limited to, a virtual reality (VR) device, a mixed reality (MR) device, a massage chair, or a 4D cinema cabin, etc. It is understood that the introduction of the electronic device 100 here is only an example and does not constitute a limitation on the embodiments of the present application. In a specific implementation, any device or apparatus including a housing and having a ventilation requirement may be the electronic device 100 described in the embodiments of the present application.

[0055] Illustratively, the electronic device 100 further includes an intermediate component 130. For easier understanding, see FIG2 , which illustrates an exploded view of the electronic device 100. As can be seen, the intermediate component 130 is positioned between the first housing 110 and the second housing 120. Illustratively, the intermediate component 130 is secured within the cavity formed by the first housing 110 and the second housing 120.

[0056] Exemplarily, the intermediate component 130 may include a printed circuit board (PCB) or a PCB assembly, etc., which is not limited in the embodiment of the present application.

[0057] As can be seen in FIG2 , for example, the first housing 110 includes an inner surface and an outer surface. The inner surface of the first housing 110 is the side surface facing the intermediate component 130. The outer surface of the first housing 110 is the side surface opposite to the inner surface of the first housing 110. Similarly, the second housing 120 includes an inner surface and an outer surface. The inner surface of the second housing 120 is the side surface facing the intermediate component 130. The outer surface of the second housing 120 is the side surface opposite to the inner surface of the second housing 120.

[0058] For example, see Figure 3. In Figure 3(a), the outer surface of the first housing 110 is provided with a first ventilation channel 1101. In Figure 3(b), the inner surface of the first housing 110 is provided with a second ventilation channel 1102. Furthermore, the first housing 110 is provided with a first through-hole 1103. This first through-hole 1103 connects the first ventilation channel 1101 and the second ventilation channel 1102.

[0059] For example, in a specific implementation, the first housing 110 may be provided with one or more first through-holes 1103, one of which is shown in FIG3 as an example. Furthermore, each first through-hole 1103 may be connected to one or more first ventilation channels 1101, and each first through-hole 1103 may be connected to one or more second ventilation channels 1102. FIG3 illustrates an example in which one first through-hole 1103 is connected to four first ventilation channels 1101 and four second ventilation channels 1102.

[0060] It is understandable that the above mainly takes the example of providing the first ventilation channel on the first shell 110. In another implementation, the first ventilation channel may be provided on the second shell 120, which will not be described in detail here.

[0061] In one possible implementation, the second air permeable channel 1102 is angularly offset relative to the first air permeable channel 1101. For ease of understanding, please refer to FIG. 4 for example. FIG. 4 is a schematic cross-sectional view of a portion of the first housing 110 including the first through-hole 1103. It can be seen that the first air permeable channel 1101, located on the outer surface of the first housing 110, is angularly offset by an angle of θ from the second air permeable channel 1102, located on the inner surface of the first housing 110. For example, the angle of this offset can be, for example, in a range from greater than 0° to less than 180°. The embodiments of this application do not limit the specific deflection angle.

[0062] In one possible implementation, the cross-sections of the first and second air channels 1101, 1102 are any planar geometric shapes, such as rectangles, triangles, semicircles, rhombuses, trapezoids, or five-pointed stars. For example, as shown in FIG. 4 , the cross-sections of the first and second air channels 1101, 1102 are rectangular. For another example, as shown in FIG. 5 and FIG. 6 , the cross-sections of the first and second air channels 1101, 1102 are triangular. The cross-sections of the first and second air channels 1101, 1102 are semicircular. It should be understood that the description of the cross-sectional shapes of the first and second air channels 1101, 1102 herein is for illustrative purposes only and does not constitute a limitation on the embodiments of the present application.

[0063] For example, as can be seen in Figures 4 to 6 above, the outer surface of the first shell 110 can be uneven. For example, a circular recessed area and some lines can be set at the position of the first through-hole 1103 in Figures 4 to 6. Similarly, the inner surface of the first shell 110 can also be uneven. Specifically, the relevant shape can be designed as needed based on aesthetics or assembly requirements, and the embodiments of the present application are not limited to this. Figures 4 to 6 are only examples and do not constitute a limitation on the embodiments of the present application.

[0064] In one possible implementation, the first and second ventilation channels 1101, 1102 are either straight or curved. For easier understanding, please refer to Figures 7 and 8 for illustration. Figures 7 and 8 use the linear shape of the first ventilation channel 1101 located on the outer surface of the first housing 110 as an example. The same applies to the linear shape of the second ventilation channel 1102 located on the inner surface of the first housing 110, and a detailed description thereof is omitted. Furthermore, Figures 7 and 8 illustrate examples where the first ventilation channels 1101 connecting to the first through-holes 1103 are two or four channels. Figure 7 shows that the linear shape of the first ventilation channel 1101 is straight. Figure 8 shows that the linear shape of the first ventilation channel 1101 is curved. It should be understood that the curved channel shape shown in Figure 8 is merely an example. In a specific implementation, the curved channel can have any curved linear shape, and this embodiment of the present application does not impose any limitation thereto.

[0065] In one possible implementation, the number, length, or channel shape of the first and second air channels 1101, 1102 can be determined based on the air permeability requirements of the electronic device 100. For example, if the electronic device 100 requires a higher air permeability, the number of the first and second air channels 1101, 1102 can be increased, the length of the first and second air channels 1101, 1102 can be extended, or the first and second air channels 1101, 1102 can be configured as straight channels. Conversely, if the electronic device 100 requires a lower air permeability, the number of the first and second air channels 1101, 1102 can be reduced, the length of the first and second air channels 1101, 1102 can be shortened, or the first and second air channels 1101, 1102 can be configured as curved channels. It is understandable that the correspondence between the air permeability requirement and the number, length or channel line shape of the air permeable channels can be set according to actual application, and the embodiments of the present application do not limit this.

[0066] In one possible implementation, the length of the first ventilation channel 1101 and the second ventilation channel 1102 can be, for example, between 8 mm and 20 mm, the width can be, for example, between 0.3 mm and 1 mm, and the depth can be, for example, between 0.1 mm and 0.5 mm. It should be understood that the dimensions of the ventilation channels described herein are merely illustrative and do not constitute limitations on the embodiments of this application.

[0067] In a possible implementation, the first air permeable channel 1101 and the second air permeable channel 1102 may be, for example, grooves or channels with openings at both ends, etc., which is not limited in this embodiment of the present application.

[0068] In a possible implementation, the number of the first air permeable channels 1101 connected to the first through holes 1103 and the number of the second air permeable channels 1102 connected to the first through holes 1103 may be equal or unequal, and this embodiment of the present application does not impose any limitation on this.

[0069] In one possible implementation, to facilitate assembly and fixation between the first housing 110 and the second housing 120, corresponding through-holes or vias are already provided on the first housing 110 or the second housing 120. These through-holes or vias can then be reused as the first through-hole 1103. For example, if the first housing 110 and the second housing 120 are fixed together by a threaded connection, the first through-hole 1103 can be a through-hole through which a threaded connector passes. For another example, if the first housing 110 and the second housing 120 are fixed together by a snap-fit ​​connection, the first through-hole 1103 can be a via for the snap-fit ​​connection. It should be understood that this description is merely illustrative and does not constitute a limitation on the embodiments of the present application. For ease of understanding, the following description will further illustrate the example of the first housing 110 and the second housing 120 being fixed together by a threaded connection.

[0070] In one possible implementation, if the first housing 110 and the second housing 120 are secured via a threaded connection, the first through-hole 1103 may be a through-hole through which a threaded connection member passes. Based on the above description, the threaded connection member may be, for example, a bolt, a stud, or a screw. For ease of understanding, the following description uses a screw as an example, as shown in FIG9 .

[0071] FIG9 is a schematic diagram further illustrating the exploded structure of the electronic device 100 shown in FIG2 . It can be seen that the electronic device 100 may also include one or more screws 140 . FIG9 illustrates nine screws 140 as an example. For coordination, the first housing 110 is provided with nine through-holes 160 . Furthermore, for coordination, the inner surface of the second housing 120 is provided with nine threaded holes 150 . The threaded holes 150 are used to engage the screws 140 to fasten the first housing 110 and the second housing 120 .

[0072] For example, the nine threaded holes 150 are raised on the inner surface of the second housing 120 to form a columnar shape, as shown in Figure 9. Alternatively, for example, the nine threaded holes 150 can be embedded in the second housing 120 so that the end faces of the threaded holes are flush with the inner surface of the second housing 120.

[0073] For example, in a specific implementation, the screw 140 may pass through the through hole 160 on the first shell 110 and then be connected to the threaded hole 150 on the second shell 120 . The screw 140 is rotated and tightened to securely connect the first shell 110 and the second shell 120 .

[0074] For example, as shown in FIG9 , the screw 140 can also pass through the intermediate component 130. To facilitate this, the intermediate component 130 is provided with nine through-holes 170. For example, in a specific implementation, the screw 140 can pass through the through-hole 160 in the first housing 110, through the through-hole 170 in the intermediate component 130, and then connect to the threaded hole 150 in the second housing 120. The screw 140 is then rotated and tightened to securely connect the first housing 110 and the second housing 120.

[0075] In another possible implementation, the screw 140 may not pass through the intermediate component 130, that is, there is no direct assembly relationship between the intermediate component 130 and the screw 140. For ease of understanding, please refer to Figure 10 for example. As can be seen in Figure 10, after the screw 140 passes through the through hole 160 on the first shell 110, it can be directly connected to the threaded hole 150 on the second shell 120, and rotating and tightening the screw 140 makes the first shell 110 and the second shell 120 tightly connected. The tight connection between the first shell 110 and the second shell 120 can also make the intermediate component 130 clamped and fixed. By way of example, Figure 10 shows an example in which the intermediate component 130 includes two sub-components (such as two PCB boards). In a specific implementation, the embodiment of the present application does not limit the number of sub-components included in the intermediate component 130.

[0076] In the implementation shown in Figures 9 or 10 above, one or more of the nine through-holes 160 can be the first through-hole 1103. As the through-hole of the first through-hole 1103, the first air permeable channel 1101 and the second air permeable channel 1102 can be provided to communicate with the through-hole. For example, Figures 9 or 10 exemplarily illustrate one of the nine through-holes 160 as the first through-hole 1103. It is understood that Figures 9 or 10 are merely examples. In a specific implementation, one or more of the nine through-holes 160 can be selected as the first through-hole 1103 based on the air permeability requirements. This embodiment of the present application is not limited to this. For example, in a specific implementation, since the screw 140 itself has threads, gaps can be formed between the threads. In addition, there are gaps between the screw 140 and the through-hole 160 (optionally, the through-hole 170) and the threaded hole 150. The gas can flow through these gaps and maintain internal and external ventilation and air pressure balance through the first air permeable channel 1101 and the second air permeable channel 1102.

[0077] For example, in order to more intuitively understand the arrangement of the first air permeable channel 1101 and the second air permeable channel 1102 in the implementation shown in Figure 9 or Figure 10, you can refer to Figures 11 and 12 for example. Figures 11 and 12 are schematic cross-sectional views of the electronic device 100 described above. Figures 11 and 12 take two first air permeable channels 1101 and two second air permeable channels 1102 as examples. As can be seen in Figures 11 and 12, the two first air permeable channels 1101 are arranged on the outer surface of the first housing 110, and the two second air permeable channels 1102 are arranged on the inner surface of the first housing 110. For example, there is an angular deflection between the first air permeable channels 1101 and the second air permeable channels 1102.

[0078] For example, to more intuitively understand the solution in FIG10 where the intermediate component 130 and the screw 140 are not directly assembled, see FIG13 for example. FIG13 is a schematic cross-sectional view of the electronic device 100. Comparing FIG13 with FIG11 , it can be seen that the screw 140 contacts and connects the first housing 110 and the second housing 120, and does not contact the intermediate component 130. After the screw 140 is tightened to secure the first and second housings 110, 120, the first and second housings 110, 120 can clamp the intermediate component 130 to secure it.

[0079] In the above introduction, the second air permeable channel 1102 is mainly provided on the inner surface of the first shell 110 as an example. In another possible implementation, in the implementation shown in Figure 9 or Figure 10 above, the second air permeable channel 1102 can be provided on the end face of the threaded hole 150. For ease of understanding, please refer to Figure 14 for example. Figure 14 shows an example of two or four second air permeable channels 1102 being provided on the end face of the threaded hole 150. In a specific implementation, gas can flow in the gaps between the threads of the screw 140 itself, as well as in the gaps between the screw 140 and the through hole and the threaded hole, and maintain internal and external ventilation and air pressure balance through the first air permeable channel 1101 and the second air permeable channel 1102.

[0080] In one possible implementation, the threaded connector may include a head and a screw, for example, see the screw 140 shown in Figures 9 or 10 above. To facilitate the flow of gas between the inside and outside, the first air permeability channel 1101 may be provided to extend beyond the area covered by the head of the threaded connector. For ease of understanding, see Figure 15 for example. Figure 15 shows a partial top view of the outer surface of the first shell 110 after the first shell 110 and the second shell 120 are fastened together. It can be seen that the threaded connector is embedded in the first shell 110 through the first through hole 1103 (covered by the head of the threaded connector), and the head of the threaded connector covers the outer surface of the first shell 110. The first air permeability channels 1101 (four of which are shown in Figure 15 as an example) extend from the first through hole 1103 beyond the area covered by the head of the threaded connector.

[0081] In one possible implementation, for application scenarios with high sealing requirements, a seal can be added around the screw 140. For example, the seal can be, for example, a sealing ring or a sealing gasket, etc., which is not limited in the embodiment of the present application. For example, the seal is arranged between the first shell 110 and the second shell 120, and is arranged around the first through hole 1103, encircling the first through hole 1103 in the middle. In this implementation, the second air permeable channel 1102 can extend beyond the coverage of the sealing ring so that a controllable air permeability can be maintained. For ease of understanding, please refer to Figures 16 and 17 for example.

[0082] Exemplarily, FIG16 shows an example of a direct assembly relationship between the intermediate component 130 and the screw 140. As can be seen in FIG16, in this implementation, two seals can be provided. One seal is provided between the first shell 110 and the intermediate component 130, and the first through hole 1103, i.e., the screw 140, is enclosed in the middle. Another seal is provided between the second shell 120 and the intermediate component 130, and similarly, the first through hole 1103, i.e., the screw 140, is enclosed in the middle. Exemplarily, in another implementation, if there is no direct assembly relationship between the intermediate component 130 and the screw 140, a sealing ring can be provided between the first shell 110 and the second shell 120.

[0083] For example, it can also be seen in Figure 16 that the second air permeable channel 1102 extends beyond the coverage of the sealing ring. For a more intuitive understanding, please also refer to Figure 17 for example. Figure 17 is a partial schematic diagram of the inner surface of the first shell 110. For example, in Figure 17, the seal encircles the first through hole 1103 in the middle. The second air permeable channel 1102 extends beyond the coverage of the sealing ring. For example, the first air permeable channel 1101 can be within the coverage of the sealing ring, as shown in Figure 17. Or, for example, the first air permeable channel 1101 can also extend beyond the coverage of the sealing ring. The embodiments of the present application do not limit this.

[0084] In one possible implementation, the electronic device 100 requires heat dissipation. For example, the electronic device 100 may be an in-vehicle controller. Exemplarily, the electronic device 100 may dissipate heat through liquid cooling or air cooling. The electronic device 100 may also include a cooling medium inlet and outlet. In this implementation, a ventilation channel may be provided near the cooling medium inlet. Because the temperature is lowest at this location and condensation is most likely to form, designing a ventilation channel there can quickly dissipate the condensation. Exemplarily, this embodiment is particularly suitable for liquid cooling. In liquid cooling scenarios, when coolant enters the hot electronic device 100, it is susceptible to condensation or condensation when it encounters cold. A high airflow allows more external moisture to enter, resulting in more condensation. The ventilation channel designed in this embodiment has a controllable air permeability, preventing the introduction of excessive external moisture. Furthermore, by providing a ventilation channel near the cooling medium inlet, condensation or condensation can be quickly dissipated. For ease of understanding, please refer to the exemplary illustration in FIG18.

[0085] For example, Figure 18 shows a schematic diagram of the appearance structure of the electronic device 100 as viewed from the first housing 110. It can be seen that the electronic device 100 includes a cooling medium inlet and a cooling medium outlet. For example, if heat is dissipated by liquid cooling, then the cooling medium inlet is the inlet of the coolant, and the cooling medium outlet is the outlet of the coolant. For example, if heat is dissipated by air cooling, then the cooling medium inlet is the air inlet, and the cooling medium outlet is the air outlet. It will be understood that the description here is merely an example, and the specific heat dissipation method of the embodiment of the present application is not limited. In addition, it can be seen in Figure 18 that the first housing 110 is provided with a plurality of through holes. For example, if the first housing 110 and the second housing 120 of the electronic device 100 are fixed by a threaded connection, then in a specific implementation, screws (such as the screws 140 described above) are also present in these first through holes 1103. For example, as shown in Figure 18, a ventilation channel can be provided in the through hole near the cooling medium inlet. The through hole provided with the ventilation channel is the above-mentioned first through hole 1103. That is, the first through hole 1103 is closer to the cooling medium inlet than the through hole without the air permeable channel. FIG18 shows the outer surface of the first housing 110, so the first air permeable channel 1101 is visible.

[0086] It should be understood that what is shown in FIG18 above is merely an example and does not constitute a limitation to the embodiments of the present application.

[0087] In one possible implementation, the electronic device 100 may also be provided with a moisture absorption module. This module may include, for example, a moisture-absorbing material such as silica gel, activated carbon, bamboo charcoal, or polymer fibers, and may be used to absorb moisture from within the electronic device 100. In this implementation, a ventilation channel may be provided near the moisture absorption module. This ventilation channel allows for rapid evaporation of moisture absorbed by the moisture absorption module. For ease of understanding, please refer to FIG19 for an example.

[0088] For example, Figure 19 shows two more moisture absorption modules than Figure 18 . The two moisture absorption modules shown in Figure 19 are merely to indicate their location within the electronic device 100. In a specific implementation, the moisture absorption modules are not visible from the outside. For example, as shown in Figure 19 , a ventilation channel can be provided in the through-hole near the moisture absorption module. The through-hole provided with the ventilation channel is the first through-hole 1103 described above. That is, first through-hole 1103 is closer to the moisture absorption module than a through-hole not provided with a ventilation channel.

[0089] It should be understood that what is shown in FIG18 above is merely an example and does not constitute a limitation to the embodiments of the present application.

[0090] The present application also provides a terminal device, which includes the electronic device 100 described in any of the aforementioned possible embodiments. For example, the terminal device can be a vehicle, drone, robot, or other means of transportation. Of course, the terminal device can also be replaced with industrial equipment, entertainment and leisure equipment, etc. This application does not limit the devices that can be used with the electronic device 100.

[0091] In summary, the electronic device provided by the embodiments of the present application can achieve low-cost ventilation while reducing the introduction of external moisture, achieving internal and external pressure balance, and avoiding failure of the breathing effect at the sealed interface. This ventilation solution is directly formed into the housing of the electronic device itself, eliminating the need for a ventilation valve, a ventilation membrane, installation, inspection, and low cost. Furthermore, by controlling the shape, length, and deflection angle of the ventilation channel, the air permeability can be controlled, embracing a wide range of applications.

[0092] It should be understood that in the various embodiments of the present application, the size of the serial number of each process does not mean the order of execution.
