Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of electronic devices, and in particular to an electronic device. Background Art

[0002] With the continuous development of electronic devices (such as mobile phones), people's performance requirements for electronic devices are increasing year by year, and the heat generated by some components inside electronic devices is also increasing. Therefore, a heat dissipation device is provided inside the electronic device to dissipate heat from components with large heat generation.

[0003] However, due to the limitation of the structural design of existing electronic equipment, the heat dissipation device cannot exert a better heat dissipation capability, resulting in the heat dissipation effect of the electronic equipment being less than ideal. Utility Model Content

[0004] The embodiment of the present application provides an electronic device for solving the problem that the structural design of the existing electronic devices results in an unsatisfactory heat dissipation effect.

[0005] In order to achieve the above purpose, the embodiment of the present application adopts the following technical solution:

[0006] An embodiment of the present application provides an electronic device, which includes a housing, a screen, and a heat dissipation device.

[0007] The screen is arranged on the shell and forms a receiving cavity with the shell. The shell is provided with a second vent and a first vent, and the first vent is located on a wall plate of the shell opposite to the screen. The heat dissipation device is located in the receiving cavity and is arranged opposite to the first vent.

[0008] The electronic device provided by the present application is such that the size of the first vent is no longer limited by the thickness of the electronic device by opening the first vent of the electronic device on the wall plate on the housing opposite to the screen (i.e., the back of the electronic device). In other words, a first vent with a larger size can be opened on the wall plate on the housing opposite to the screen, thereby improving the heat dissipation effect. For example, when the above-mentioned heat dissipation device is a heat dissipation fan, outside air can enter the inside of the electronic device through the above-mentioned first vent. Since the first vent is larger, the air intake is also larger, that is, more outside air can be sucked into the electronic device by the heat dissipation fan per unit time to exchange heat with the heating element, thereby improving the heat dissipation effect of the electronic device. In addition, opening the first vent on the wall plate on the housing opposite to the screen reduces the openings on the side of the electronic device to a certain extent, making the electronic device more beautiful and exquisite, and having a better visual effect.

[0009] In a possible implementation, at least one supporting rib is disposed in the first vent, and both ends of the supporting rib are fixed to the inner wall of the first vent. Thus, by disposing the supporting rib in the first vent, when a larger first vent is opened on the wall opposite to the shell and the screen, the structural strength of the wall opposite to the shell and the screen can be ensured.

[0010] In another possible implementation, in a plane parallel to the wall plate of the housing facing the screen, the width of the support rib is greater than or equal to 5 mm. This configuration avoids the support rib being too thin and insufficient in rigidity, and can ensure that the support rib plays a certain supporting and reinforcing role on the first vent.

[0011] In another possible implementation, in a plane parallel to the wall plate of the housing facing the screen, the width of the support rib is greater than or equal to 5% of the length of the support rib. This arrangement avoids the support rib being too thin and insufficient in rigidity, and can ensure that the support rib plays a certain supporting and reinforcing role on the first vent.

[0012] In another possible implementation, the electronic device further includes a dust screen disposed at the first vent. In this way, the dust screen can not only filter out dust entrained in the air entering the electronic device from the first vent, but also prevent other foreign objects with larger particle sizes from entering the electronic device and affecting the operation of the electronic device.

[0013] In another possible implementation, a groove is formed on the outer wall of the housing, the first vent is located at the bottom of the groove, and the dust screen is embedded in the groove and covers the first vent. In this way, it is not only easy to assemble the dust screen, but also possible to avoid adding extra thickness to the electronic device. For example, when the dust screen is embedded in the groove, the surface of the dust screen away from the screen is flush with the outer surface of the wall plate of the housing opposite to the screen, and does not protrude from the housing.

[0014] In another possible implementation, the electronic device further includes a decorative component, which is disposed on an outer wall of the housing, and an air intake grille is provided on the decorative component, and the air intake grille covers the first vent.

[0015] In this way, the first vent is covered by the decorative piece, that is, the first vent is hidden under the decorative piece, so that the first vent is more concealed and has less impact on the appearance of the electronic device. In addition, an air intake grille is provided in the area overlapping the first vent on the decorative piece, that is, outside air can enter the first vent through the air intake grille, so that the normal function of the first vent is not affected.

[0016] In another possible implementation, the decorative member includes a first part and a second part, and the air intake grille is arranged on the first part. The electronic device also includes a camera module, which is arranged in the accommodating cavity, and a light-transmitting hole is provided on the second part, and the light-entering surface of the camera module is arranged opposite to the light-transmitting hole. In this way, the first vent and the camera module are decorated respectively by the first part and the second part of the decorative member, so that the integrity of the appearance of the electronic device is better. In addition, a light-transmitting hole opposite to the light-entering surface of the camera module is provided on the second part of the decorative member, so that the decorative member does not block the line of sight of the camera module.

[0017] In another possible implementation, the electronic device further includes a light-transmitting cover, which is embedded in the light-transmitting hole. In this way, the light-transmitting cover can prevent foreign objects such as dust from entering the electronic device or the camera module through the light-transmitting hole on the decorative component, and the light-transmitting cover can also prevent the camera module from being scratched or hit by foreign objects.

[0018] In another possible implementation, the first part and the second part are connected and distributed along the length direction of the electronic device, so that the camera module and the first vent are also distributed along the length direction of the electronic device, making the appearance of the electronic device more coordinated and beautiful.

[0019] In another possible implementation, the housing includes a middle frame and a back plate, the screen and the back plate are respectively arranged on both sides of the middle frame, the screen, the middle frame and the back plate are arranged to form a receiving cavity, and the first vent is arranged on the back plate. In this way, the production, processing and assembly of the housing are facilitated.

[0020] In another possible implementation, a second vent is provided on the housing, so that outside air can enter the electronic device through the first vent, absorb heat from the heating element, and then be discharged through the second vent, which is conducive to forming air convection in the electronic device, thereby improving heat dissipation efficiency.

[0021] In another possible implementation, there is at least one first vent and at least one heat dissipation device, wherein at least one heat dissipation device is disposed at each first vent; or each heat dissipation device corresponds to at least one first vent.

DETAILED DESCRIPTION

[0040] In order to make the purpose, technical solution and advantages of the application more clear, the present application is further described in detail below in conjunction with the embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0041] In the description of the present application, it should be clarified that the terms "vertical", "lateral", "longitudinal", "front", "rear", "left", "right", "up", "down", "horizontal" and the like indicating directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present application, and do not mean that the devices or elements referred to must have a specific direction or position, and therefore cannot be understood as limiting the present application. The "quantity" mentioned above cannot be understood as limiting the present application.

[0042] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0043] The embodiment of the present application provides an electronic device 01. Specifically, the electronic device 01 may be a portable electronic device or other types of electronic devices. For example, the electronic device may be a mobile phone, a tablet personal computer, a laptop computer, a personal digital assistant (PDA), a monitor, a camera, a personal computer, a notebook computer, a wearable device, etc. For the convenience of description, the following examples are all taken as an example in which the electronic device 01 is a tablet computer.

[0044] See also Figure 1 and Figure 2 As shown, Figure 1 This is a schematic diagram of the overall structure of the electronic device 01 provided in the embodiment of the present application. Figure 2 For the above Figure 1 Exploded diagram of the structure of the electronic device 01. As can be seen from the above, in this embodiment, the electronic device 01 is a tablet computer, and the electronic device 01 can be in an approximately rectangular plate-shaped structure. The electronic device 01 can include a screen 10, a housing 20, a camera module 30 and a mainboard 40.

[0045] For the convenience of the following description, an XYZ coordinate system is established, and the width direction of the electronic device 01 is defined as the X-axis direction, the length direction of the electronic device 01 is defined as the Y-axis direction, and the thickness direction of the electronic device 01 is defined as the Z-axis direction. Therefore, this application does not make any special restrictions on this. It can be understood that Figure 1 and Figure 2 Only some components of the electronic device 10 are schematically shown, and the actual shapes, sizes, positions and structures of these components are not subject to the present invention. Figure 1 and Figure 2 restrictions.

[0046] The above-mentioned screen 10 is used to display images, videos, etc. The screen 10 may include a light-transmitting cover plate 11 and a display screen 12 (English name: panel, also called display panel), and the light-transmitting cover plate 11 and the display screen 12 are stacked. The material of the light-transmitting cover plate 11 includes but is not limited to glass. For example, the light-transmitting cover plate 11 can adopt an ordinary light-transmitting cover plate to protect the display screen to avoid damage to the display screen due to external force, and it can play a dust-proof role. Alternatively, the light-transmitting cover plate 11 can also adopt a light-transmitting cover plate with a touch function, so that the electronic device 01 has a touch function, which makes it more convenient for users to use. Therefore, the present application does not specifically limit the specific material of the light-transmitting cover plate 11.

[0047] In addition, the display screen 12 may be a flexible display screen or a rigid display screen. For example, the display screen 12 may be an organic light-emitting diode (OLED) display screen, an active-matrix organic light-emitting diode or an active-matrix organic light-emitting diode (AMOLED) display screen, a mini organic light-emitting diode (MIL-E) display screen, a micro light-emitting diode (MIL-E) display screen, a microorganic light-emitting diode (MIL-E) display screen, a quantum dot light-emitting diode (QLED) display screen, or a liquid crystal display (LCD).

[0048] The housing 20 is used to protect the electronic components inside the electronic device 01. The housing 20 may include a back plate 21 and a middle frame 22, wherein the screen 10 and the back plate 21 are respectively fixed on both sides of the middle frame 22, wherein the light-transmitting cover plate 11 of the screen 10 is fixed on the middle frame, and the light-transmitting cover plate 11, the middle frame 22 and the back plate 21 are jointly arranged to form a receiving cavity 100, wherein the display screen 12, the main board 40 and the camera module 30 are all arranged in the receiving cavity 100.

[0049] The back plate 21 is located on a side of the display screen 12 away from the transparent cover plate 11 , and is stacked with the transparent cover plate 11 and the display screen 12 . The middle frame 22 is located between the transparent cover plate 11 and the back plate 21 .

[0050] It is understandable that the middle frame 22 and the back plate 21 can be connected by welding, bonding, clamping, etc. Alternatively, the middle frame 22 and the back plate 21 can also be connected to form an integrated structure, that is, the middle frame 22 and the back plate 21 form a structural component as a whole, and there is no separation fault between the two. Compared with the split structure, the integrated structure is more solid, beautiful, and easy to assemble.

[0051] The shell 20 may be made of a non-metallic material, such as plastic, glass, etc., or a metallic material, such as aluminum alloy, titanium alloy, etc., which is not particularly limited in the present application.

[0052] The mainboard 40 is used to set the electronic components of the electronic device 10 and realize the electrical connection between the electronic components. For example, the electronic components can be a control chip (such as a system on chip, SOC), a graphics processing unit (GPU), a universal flash storage (UFS), an earpiece, a flash module, and the camera module 30.

[0053] The camera module 30 is used to realize video or image shooting and can realize auto focus (AF, AutoFocus), so it can be applied to various shooting scenes. Figure 2 As shown, the camera module 30 is arranged at the edge of the back plate 21. Alternatively, the camera module 30 can be located at the upper middle position of the back plate 21 ( Figure 2 Therefore, the present application does not specifically limit the specific position of the camera module 30.

[0054] Specifically, the camera module 30 has a light incident surface and a light emitting surface. The light incident surface may be the light incident surface of the internal lens of the camera module 30, and the light emitting surface may be the light emitting surface of the internal lens of the camera module 30. The light incident surface of the camera module 30 faces the back plate 21. Accordingly, in order to allow external light to pass through the back plate 21 and illuminate the light incident surface of the camera module 30, a light-transmitting window 20d is provided on the back plate 21. The light incident surface of the camera module 30 is arranged opposite to the light-transmitting window 20d. After the external light passes through the light-transmitting window 20d, it enters the camera module 30 from the light incident surface of the camera module 30. The camera module 30 converts the received optical signal into a digital signal, outputs it to a digital signal processor (DSP, Digital Signal Processing) for image signal enhancement and compression optimization, and finally transmits it to the DSP. Figure 2 An image is displayed on the display screen 12 shown.

[0055] Furthermore, in order to prevent foreign objects such as dust from entering the electronic device 01 or the camera module 30 through the light-transmitting window 20d on the back plate 21, a light-transmitting cover 50 is provided on the back plate 21, and the light-transmitting cover 50 covers the light-transmitting window 20d. The light-transmitting cover 50 can also prevent the camera module 30 from being scratched or hit by foreign objects.

[0056] Among them, some of the above-mentioned electronic devices will generate heat when working. These electronic devices that can generate heat can also be called heating elements, and are referred to as heating elements 90 in the following embodiments. In order to reduce the risk of damage to the heating element 90 due to heat, the above-mentioned electronic device 01 can also include a heat dissipation device 60, which is arranged in the above-mentioned accommodating cavity 100, and a vent 20c is opened on the housing 20. The heat dissipation device 60 is correspondingly arranged at the vent 20c, and the heat dissipation device 60 is used to dissipate heat and cool the heating element 90.

[0057] Please continue to see Figure 2 As shown, the vent 20 c is generally opened on the side of the electronic device 01 , that is, opened on the middle frame 22 .

[0058] For example, the vent 20c can be in the shape of a long strip, and the width of the vent 20c is always limited by the thickness of the middle frame 22 (assuming that the length of the electronic device 01 is 300 mm, the width is 200 mm, and the thickness is 10 mm, then the width of the vent 20c can only be less than 10 mm), resulting in an unsatisfactory heat dissipation effect. If the area of ​​the vent 20c needs to be increased, the vent 20c can only be extended along the length direction of the electronic device 01 (i.e., the length of the vent 20c is increased), which will adversely affect the consistency of the appearance of the electronic device 01.

[0059] For another example, the vent 20c can be circular. In this case, the maximum diameter of the vent 20c is always smaller than the thickness of the middle frame 22 (assuming that the length of the electronic device 01 is 300mm, the width is 200mm, and the thickness is 10mm, then the maximum diameter of the vent 20c can only be less than 10mm), so the heat dissipation effect is not ideal.

[0060] To solve the above problems, the present application embodiment provides another electronic device 01, see Figure 3 , Figure 4 As shown, Figure 3 This is a schematic diagram of the overall structure of another electronic device 01 provided in an embodiment of the present application. Figure 4 for Figure 3 Structural explosion diagram of electronic device 01.

[0061] The electronic device 01 may include the screen 10, the housing 20, the mainboard 40, the camera module 30, the light-transmitting cover 50 and the heat dissipation device 60. The screen 10 and the back plate 21 are respectively fixed to the two sides of the middle frame 22, and the screen 10, the middle frame 22 and the back plate 21 are jointly surrounded to form a receiving cavity 100, and the mainboard 40, the camera module 30 and the heat dissipation device 60 are all arranged in the receiving cavity 100.

[0062] The back plate 21 on the housing 20 is disposed opposite to the screen 10 , a first vent 20 a is provided on the back plate 21 , and the heat dissipation device 60 is disposed opposite to the first vent 20 a .

[0063] The first vent 20a may be in a regular shape such as a circle, an ellipse, a rectangle, or other irregular shapes, and the present application does not impose any special limitation on this.

[0064] In this way, by opening the first vent 20a on the wall plate (i.e., the back plate 21) of the housing 20 opposite to the screen 10, the size of the first vent 20a will not be limited by the width of the middle frame 22 (along the thickness direction of the electronic device 01), that is, a larger first vent 20a can be opened on the back plate 21, thereby improving the heat dissipation effect. For example, the length of the electronic device 01 is 300mm, the width is 200mm, and the thickness is 10mm. The first vent 20a is circular, and its diameter can be much larger than the thickness of the electronic device 01. For example, the diameter of the first vent 20a can be 20mm, 30mm, etc.

[0065] Moreover, opening the first vent 20a on the back panel 21 also reduces the number of openings on the middle frame 22 of the electronic device 01 to a certain extent. Since the user is always facing the screen 10 of the electronic device 01 when pointing to the electronic device 01, the user will not observe the first vent 20a on the back panel 21 at this time, thereby making the electronic device 01 look more beautiful and refined, and having a better visual effect.

[0066] It is understandable that one or more first vents 20a may be provided. One or more heat sinks 60 may be provided. When there are multiple first vents 20a, at least one heat sink 60 is provided at each first vent 20a. When there are multiple heat sinks 60, each heat sink 60 corresponds to at least one first vent 20a.

[0067] Moreover, in the thickness direction (Z-axis direction) of the electronic device 01, the heat dissipation device 60 and the first vent 20a may overlap partially or completely, as long as the heat dissipation device 60 and the first vent 20a can cooperate with each other functionally to achieve heat dissipation, and the present application does not make any special limitations on this.

[0068] For example, see Figure 5 As shown, Figure 5 Schematic diagram of the distribution of the heat dissipation device 60 and the first vent 20a provided in the embodiment of the present application Figure 1 . Figure 5In the figure, the heat dissipation device 60 is provided with one (as shown by the dotted line), the first vent 20a is provided with two, and the two first vents 20a are distributed along the Y-axis direction, the first vent 20a is circular, and the two first vents 20a are all located within the positive projection of the heat dissipation device 60 on the back plate 21.

[0069] For another example, see Figure 6 As shown, Figure 6 Schematic diagram of the distribution of the heat dissipation device 60 and the first vent 20a provided in the embodiment of the present application Figure 2 . Figure 6 In the figure, there is one first vent 20a, and four heat sinks 60 are provided (as shown by dotted lines in the figure). The first vent 20a is circular, and the orthographic projections of the four heat sinks 60 on the back plate 21 are all located in the first vent 20a.

[0070] For the convenience of description, the following examples are provided with only one first vent 20a and one heat dissipation device 60.

[0071] In the embodiment of the present application, the heat dissipation device 60 can be a device that draws air with a lower outside temperature into the electronic device 01 to dissipate heat from the heating element 90, such as a cooling fan, an air pump, etc. In this case, opening a larger first vent 20a on the back plate 21 is equivalent to increasing the air intake of the heat dissipation device 60, that is, more outside air can be drawn into the electronic device 01 by the heat dissipation device 60 per unit time to exchange heat with the heating element 90 (that is, absorb the heat generated by the heating element 90), thereby improving the heat dissipation effect of the electronic device 01.

[0072] In addition, the heat dissipation device 60 can also be a device that actively absorbs the heat of the heating element 90, and then releases the absorbed heat from the first vent 20a to the outside in the form of thermal radiation to dissipate the heat of the heating element 90, such as a temperature equalizer, a heat pipe, a heat dissipation fin, etc. In this case, opening a larger first vent 20a on the back plate 21 is equivalent to increasing the contact area between the heat dissipation device 60 and the outside air, so that the heat dissipation device 60 can radiate heat outward faster, thereby improving the heat dissipation effect of the electronic device 01.

[0073] For the convenience of description, the following description is made by taking the heat dissipation device 60 as a heat dissipation fan as an example.

[0074] Please return Figure 4 As shown, the heat dissipation device 60 is a heat dissipation fan. In the illustrated position, the first vent 20a is opened at a position near the left edge of the upper portion of the back plate 21. The air inlet of the heat dissipation fan ( Figure 4 The heat dissipation fan is located on one side of the heat dissipation fan close to the back plate 21, and the air inlet of the heat dissipation fan faces the first vent 20a, and the air outlet of the heat dissipation fan ( Figure 4 ) toward the inner wall of the middle frame 22.

[0075] At this time, the outside air can be sucked into the electronic device 01 by the cooling fan through the above-mentioned first ventilation port 20a. Since the first ventilation port 20a is larger, the air intake volume is also larger, that is, more outside air can be sucked into the electronic device 01 by the cooling fan per unit time to exchange heat with the heating element 90, thereby improving the heat dissipation effect of the electronic device 01.

[0076] It can be understood that the above embodiment is only one possible example. In other possible examples, the first vent 20a can also be opened at other positions on the back panel 21, such as the geometric center of the back panel 21, the top corner of the back panel 21, etc., and the present application does not make any special limitation on this.

[0077] Based on this, the electronic device 01 provided in the embodiment of the present application, by opening the first ventilation hole 20a on the wall panel of the shell 20 opposite to the screen 10 (that is, on the back panel 21), so that the size of the first ventilation hole 20a is no longer limited by the thickness of the electronic device 01, that is, a larger first ventilation hole 20a can be opened to improve the heat dissipation effect of the electronic device 01.

[0078] On the basis of the above, a second vent 20b may be provided on the housing 20. The second vent 20b may be provided on the back plate 21 and spaced apart from the first vent 20a. Alternatively, the second vent 20b may also be provided on the middle frame 22. The present application does not specifically limit the position of the second vent 20b.

[0079] In this way, outside air can enter the electronic device 01 through the first vent 20a, and after absorbing the heat of the heating element 90, it can be discharged through the second vent 20b, which is equivalent to forming an air flow channel 101 connecting the first vent 20a and the second vent 20b in the electronic device 01, which is conducive to the formation of air convection in the electronic device 01, thereby improving the heat dissipation efficiency.

[0080] For example, refer back to Figure 4 The middle frame 22 is rectangular, and has a first wall plate 221 and a second wall plate 222 parallel to the YZ plane, and a third wall plate 223 and a fourth wall plate 224 parallel to the XZ plane. The second vent 20b is provided on the first wall plate 221. The first vent 20a is provided on the back plate 21 at an edge position close to the first wall plate 221.

[0081] See also Figure 7 , Figure 8 As shown, Figure 7 for Figure 4 A partial enlarged view of the middle A. Figure 8 Schematic diagram of the air flow channel 101 formed between the first vent 20a and the second vent 20b. In the illustrated position, the first vent 20a is opened at the upper part of the back plate 21 near the left edge, and the second vent 20b is set on the first wall plate 221, and the second vent 20b is located below the first vent 20a, so that an L-shaped air flow channel 101 ( Figure 8 The inlet of the air channel 101 is the first vent 20a, the outlet of the air channel 101 is the second vent 20b, and the heating element 90 is disposed on the air channel 101.

[0082] Heat dissipation device 60( Figure 8 The outside air is sucked into the electronic device 01 through the first vent 20a by the vent fan. When this part of the air flows along the air channel 101, it can take away part of the heat of the heating element 90, and then it is discharged from the second vent 20b under the driving of the wind pressure generated by the vent fan. Figure 8 The dotted arrow in the middle indicates the direction of air flow), and thus, the outside air is continuously sucked in and discharged, thereby achieving efficient heat dissipation of the heating element 90.

[0083] It is understandable that the second vent 20b may be in a regular or irregular shape such as a strip, a circle, an ellipse, a diamond, etc. In addition, the second vent 20b may be a single opening, or the second vent 20b may be composed of a plurality of smaller secondary holes 20f arranged and combined, and the present application does not make any special limitation on this.

[0084] For example, see Figure 7 As shown. The second vent 20b is composed of 8 secondary holes 20f of equal size, and the 8 secondary holes 20f are arranged in four rows and two columns (i.e., a 4×2 matrix). Among them, the secondary hole 20f is in the shape of a long strip, and the width direction of the secondary hole 20f is the same as the thickness direction (Z-axis direction) of the electronic device 01, and the length direction of the secondary hole 20f is the same as the length direction (Y-axis direction) of the electronic device 01. Such a setting is more beautiful while ensuring that the area of ​​the second vent 20b remains unchanged.

[0085] Furthermore, in order to avoid excessive reduction of the overall structural strength of the back plate 21 due to the large first vent 20a, a supporting rib 23 is provided in the first vent 20a, and both ends of the supporting rib 23 are connected to the inner wall of the first vent 20a.

[0086] There may be one or more supporting ribs 23. The multiple supporting ribs 23 may cross each other or be arranged in parallel with each other, and may be selected according to actual needs, and this application does not make any special restrictions on this.

[0087] For example, see Fig. 9 As shown, Fig. 9 for Figure 3 The first vent 20a is circular, and two straight and long support ribs 23 are provided in the first vent 20a, namely the first support rib 23a and the second support rib 23b, which are parallel to the first diameter d1 of the first vent 20a and are respectively located on both sides of the first diameter d1.

[0088] Ideally, the thinner the support rib 23 is, the smaller the impact on the first vent 20a is. However, to avoid the support rib 23 being too thin and insufficiently rigid, the support rib 23 can ensure that it plays a certain supporting and reinforcing role on the first vent 20a. Therefore, the width of the support rib 23 needs to be greater than or equal to 0.5 mm. For example, the width of the support rib 23 can be 0.7 mm, 0.8 mm, 1.0 mm, etc.

[0089] The above width refers to the width of the supporting rib 23 in a plane parallel to the back plate 21 .

[0090] In other embodiments, the width of the support rib 23 is greater than or equal to 5% of its length. For example, the width of the support rib 23 can be 8%, 10%, 15% of its length.

[0091] The above-mentioned width and length refer to the width and length of the supporting rib 23 in a plane parallel to the back plate 21 , respectively.

[0092] When there are multiple support ribs 23 with different lengths, the widths of the multiple support ribs 23 can be the same for ease of production and processing. In this case, the widths of all support ribs 23 should be greater than or equal to 5% of the length of the shortest support rib 23 .

[0093] For example, see Fig. 9 As shown, the first support rib 23a and the second support rib 23b are both parallel to the first diameter d1 of the first vent 20a, and are respectively located on both sides of the first diameter d1. The second support rib 23b is longer than the first support rib 23a. However, the width of the first support rib 23a and the width of the second support rib 23b are the same, both of which are 5% of the length of the first support rib 23a.

[0094] In some embodiments, see Fig.10 , Fig.11 As shown, Fig.10 This is an exploded view of the structure of another electronic device 01 provided in an embodiment of the present application. Fig.11 for Fig.10 A partial enlarged view of the area C. In order to prevent foreign matter such as dust from entering the electronic device 01 through the first vent 20a and interfering with the operation of the electronic device 01, a dustproof net 70 is provided at the first vent 20a.

[0095] It should be noted that the dustproof net 70 can be set on the inner side of the back plate 21 and cover the first vent 20a, or can be set on the outer side of the back plate 21 and cover the first vent 20a, or can be embedded in the first vent 20a, and this application does not make any special restrictions on this.

[0096] When the dustproof net 70 is arranged outside the back plate 21 and covers the first vent 20a, a groove 20e is provided on the outer surface of the back plate 21, the first vent 20a is arranged at the bottom of the groove 20e, and the dustproof net 70 is embedded in the groove 20e. In this way, it is not only easy to assemble the dustproof net 70, but also can avoid adding extra thickness to the electronic device 01.

[0097] For example, see Fig.10 , Fig.11 , wherein the first vent 20a is circular, and a first supporting rib 23a and a second supporting rib 23b are provided in the first vent 20a. The cross section of the groove 20e (parallel to the XY plane) is rectangular, the shape of the dust screen 70 corresponds to the shape of the groove 20e, the length and width of the cross section of the groove 20e (parallel to the XY plane) are both greater than the diameter of the first vent 20a, the thickness of the dust screen 70 (parallel to the Z axis direction) is equal to the depth of the groove 20e (parallel to the Z axis direction), when the dust screen 70 is embedded in the groove 20e, and the side surface of the dust screen 70 close to the screen 10 is in contact with the bottom of the groove 20e, and the side surface of the dust screen 70 away from the screen 10 is flush with the outer surface of the back plate 21, and does not protrude from the housing 20, making the electronic device 01 more beautiful and thin.

[0098] The dustproof net 70 can be a metal mesh made of copper, aluminum, aluminum alloy, stainless steel, etc., or a plastic mesh made of PVC (Polyvinyl chloride), PET (Polyethylene terephthalate), nylon, etc.

[0099] In some embodiments, see Fig.12 As shown, Fig.12 This is a structural explosion diagram of another electronic device 01 provided in an embodiment of the present application. Fig.12In the electronic device 01, the decorative member 80 is further provided on the outer wall of the back plate 21 and covers the first vent 20a, and an air intake grille 80a is provided in the area of ​​the decorative member 80 overlapping with the first vent 20a.

[0100] In this way, the first vent 20a can be covered by the decorative member 80, which is equivalent to hiding the first vent 20a under the decorative member 80, making the first vent 20a more concealed and having less impact on the appearance of the electronic device 01. In addition, the air intake grille 80a is provided in the area overlapping the first vent 20a on the decorative member 80, so as not to affect the normal function of the first vent 20a.

[0101] It should be noted that the air intake grille 80a may be in a grid shape, a stripe shape, or other structural shapes, and the present application does not impose any special limitation on this.

[0102] For example, see Fig.13 As shown, Fig.13 for Fig.12 Schematic diagram of the structure of the decorative part 80. The decorative part 80 is a rectangular plate-shaped structure, and the air intake grille 80a is striped. At this time, the air intake grille 80a is equivalent to a plurality of parallel long strip openings 811 formed on the decorative part 80, and two adjacent openings 811 are arranged at intervals to form a baffle bar 812 of the air intake grille 80a. At this time, in the thickness direction of the electronic device 01, the baffle bar 812 of the air intake grille 80a can also be used to block the support rib 23 in the first vent 20a on the back plate 21, that is, the orthographic projection of the baffle bar 812 in the XY plane can completely cover the orthographic projection of the support rib 23 in the XY plane.

[0103] When the user observes the back plate 21 of the shell 20 along the thickness direction of the electronic device 01, the barrier strips 812 of the air intake grille 80a completely cover the supporting ribs 23 in the first vent 20a, thereby making the electronic device 01 more beautiful and improving the user's viewing experience.

[0104] For further information, see Fig.14 , Fig.15 and Fig.16 As shown, Fig.14 This is a schematic diagram of the overall structure of an electronic device 01 provided in an embodiment of the present application. Fig.15 for Fig.14 The structural explosion diagram of electronic equipment 01, Fig.16 for Fig.15Schematic diagram of the structure of the decorative member 80. The decorative member 80 may include a first portion 81 and a second portion 82 connected to each other, and the air intake grille 80a is arranged on the first portion 81. The second portion 82 is provided with a light-transmitting hole 80b, and the light-entering surface of the camera module 30 is arranged with the light-transmitting hole 80b, and the light-transmitting cover 50 is embedded in the light-transmitting hole 80b. External light can pass through the light-transmitting hole 80b on the decorative member 80, the light-transmitting cover 50 and the light-transmitting window 20d on the back plate 21 to irradiate the light-entering surface of the camera module 30.

[0105] In this case, it is equivalent to using only one decorative piece 80 to decorate the first vent 20a and the light-transmitting cover 50 at the same time, which can avoid the back of the electronic device 01 from being excessively divided and improve the integrity.

[0106] Furthermore, the first portion 81 and the second portion 82 are connected and distributed along the length direction of the electronic device 01. In this way, the light-transmitting cover 50 and the first vent 20a are also distributed along the length direction of the electronic device 01, which is more coordinated and beautiful.

[0107] For example, see Fig.16 As shown, Fig.16 The first part 81 and the second part 82 of the middle decorative member 80 are both plate-shaped structures and are connected along the length direction (Y-axis direction) of the electronic device 01. The air intake grille 80a on the first part 81 is striped, and the light-transmitting hole 80b on the light-transmitting cover 50 and the second part 82 are both circular. When the decorative member 80 is attached to the back plate 21, the air intake grille 80a covers the first vent 20a, and the light-transmitting cover 50 is embedded in the light-transmitting hole 80b.

[0108] In the description of this specification, specific features, structures, materials or characteristics may be combined in an appropriate manner in any one or more embodiments or examples.
