Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of electronic equipment, and particularly relates to an electronic equipment. BACKGROUND

[0002] Waterproof performance is an important capability of electronic equipment such as mobile phones. Generally, the edge of the display screen is connected with the frame, so that the back of the display screen and the frame can enclose a sealed chamber. In order to prevent the display screen from being arched due to changes in air pressure when the electronic equipment is used at different altitudes, a gas balance hole is usually provided on the frame, which extends from the outer surface of the frame to the sealed chamber, so that the sealed chamber can exchange gas with the outside.

[0003] In addition, in order to prevent water vapor from entering the sealed chamber through the gas balance hole and causing damage to the display screen, a waterproof gas permeable film is usually provided on the inner side of the gas balance hole. Under normal pressure, the movement speed of water vapor is relatively small and does not damage the reliability of the waterproof gas permeable film. However, once the gas balance hole is impacted by high-pressure water flow, the waterproof gas permeable film is easily broken by the high-pressure water flow, causing water vapor to enter the sealed chamber and damage the display screen, which adversely affects the reliability of the electronic equipment. SUMMARY

[0004] The purpose of the embodiments of the application is to provide an electronic equipment to solve the problem that the waterproof gas permeable film is easily damaged when the current electronic equipment is impacted by high-pressure water flow, causing water vapor to erode the display screen and other devices, which adversely affects the reliability of the electronic equipment.

[0005] The embodiments of the application provide an electronic equipment, which comprises a display screen, a frame, a support, a waterproof gas permeable film and an elastic diaphragm. The display screen is arranged on one side of the frame and encloses a containing cavity with the frame. The frame is provided with a gas balance hole. The support is arranged on the side of the frame facing the display screen, and the support is provided with a communication hole. The gas balance hole communicates with the containing cavity through the communication hole. The waterproof gas permeable film is arranged between the first end of the communication hole close to the containing cavity and the containing cavity. The elastic diaphragm is arranged between the second end of the communication hole close to the gas balance hole and the gas balance hole. The elastic diaphragm has a first state and a second state. In the process of switching from the second state to the first state under the action of an external force, the elastic diaphragm elastically deforms to block the communication hole. When the external force is removed, the elastic diaphragm restores the deformation, and the communication hole communicates with the gas balance hole.

[0006] The electronic device disclosed by the embodiments of the present application has a display screen arranged on one side of a frame body, and the display screen can form a containing cavity together with the frame body. A support is arranged on the side of the frame body facing the display screen. The frame body is provided with a gas permeable hole, and the support is provided with a communication hole. The gas permeable hole can communicate with the containing cavity through the communication hole. A waterproof and gas permeable film is arranged between the first end of the communication hole close to the containing cavity and the containing cavity. This can ensure that the containing cavity can exchange gas with the outside of the electronic device, and the water vapor from the outside cannot enter the containing cavity through the gas permeable hole and the communication hole, and the display screen and other devices are not damaged.

[0007] Meanwhile, an elastic diaphragm is arranged between the second end of the communication hole close to the gas permeable hole and the gas permeable hole. The elastic diaphragm can be elastically deformed when subjected to an external force. Correspondingly, the elastic diaphragm can restore its deformation when the external force is removed. Therefore, in the embodiments of the present application, the elastic diaphragm has a first state and a second state. When the elastic diaphragm is subjected to an external force, the elastic diaphragm can switch from the second state to the first state, so that the elastic diaphragm can be elastically deformed to block the communication hole. Correspondingly, when the external force is removed, the elastic diaphragm can restore its deformation, so that the communication hole and the gas permeable hole are reconnected.

[0008] Based on the above-mentioned electronic device disclosed by the present application, if high-pressure water flows into the electronic device through the gas permeable hole, it will impact the elastic diaphragm as an external force, causing the elastic diaphragm to be elastically deformed, and then the elastic diaphragm blocks the communication hole, thereby preventing the high-pressure water from flowing through the gas permeable hole into the communication hole. This can prevent the high-pressure water from impacting the waterproof and gas permeable film between the end of the communication hole away from the gas permeable hole and the containing cavity, ensure that the electronic device has relatively good waterproof performance, and make the waterproof and gas permeable film have relatively strong persistence. Of course, when the high-pressure water no longer impacts the elastic diaphragm, that is, when the external force acting on the elastic diaphragm is removed, the elastic diaphragm can restore its deformation, and then the communication hole and the gas permeable hole restore the state of mutual communication, ensuring that the gas permeable hole can still provide the containing cavity of the electronic device with the function of balancing air pressure.

DETAILED DESCRIPTION

[0011] The technical solutions in the embodiments of the present application will be clearly described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present application.

[0012] The terms "first", "second", and the like in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are usually a class, and are not limited to the number of objects, for example, the first object can be one or more. In addition, "and / or" in the specification and claims means at least one of the connected objects, and the character " / ", generally indicates that the front and rear associated objects are in an "or" relationship.

[0013] As Figures 1-8 shown, the present application discloses an electronic device, which can be a watch, a mobile phone or a tablet computer, etc. As Figure 1 shown, the electronic device includes a display screen, a frame 100, a waterproof and breathable membrane 200, and an elastic diaphragm 300, of course, the electronic device usually also includes a battery and other devices.

[0014] The display screen is used to provide display function, and the display screen is connected with the frame 100. The frame 100 can be made of plastic or metal, and the two can be connected by adhesion.

[0015] In order to prevent the electronic device from swelling due to the change of air pressure in different altitudes, so as to ensure that the service life of the display screen and other devices of the electronic device is relatively high, the frame 100 of the electronic device disclosed in the embodiment of the application is provided with a ventilation hole 111 and a communication hole 122a. The ventilation hole 111 is communicated with the accommodation cavity through the communication hole 122a, which enables the accommodation cavity to be communicated with the outside of the electronic device through the ventilation hole 111 and the communication hole 122a, preventing the accommodation cavity from swelling due to the change of external air pressure and causing the display screen to arch.

[0016] Specifically, the first end of the communication hole 122a close to the accommodation cavity is communicated with the accommodation cavity, and the second end of the communication hole 122a away from the accommodation cavity is communicated with the ventilation hole 111. At the same time, by extending the end of the ventilation hole 111 away from the communication hole 122a to the outer surface of the frame 100, it can be ensured that the accommodation cavity can be communicated with the outside of the electronic device through the communication hole 122a and the ventilation hole 111, and the accommodation cavity can exchange gas with the space outside the electronic device.

[0017] It should be noted that in the electronic device disclosed in the embodiment of the application, no matter how the structure of the frame 100, the ventilation hole 111 and the communication hole 122a is, the accommodation cavity can only be communicated with the ventilation hole 111 through the communication hole 122a. In the case that the frame 100 includes multiple parts, and the ventilation hole 111 and the communication hole 122a are located on different parts of the frame 100, the design principle of the application is also to make the accommodation cavity only be communicated with the ventilation hole 111 through the communication hole 122a. Even if there is an assembly gap between the multiple parts of the frame 100, in theory, it is believed that the gap does not have the ability to communicate the accommodation cavity with the ventilation hole 111.

[0018] Further, in the case that the frame 100 includes multiple parts, the adjacent parts can be bonded with each other by glue or double-sided adhesive 400 and other materials to prevent the accommodation cavity from being communicated with the ventilation hole 111 through the gap between the multiple parts of the frame 100.

[0019] Of course, in order to prevent the water vapor and other impurities from the outside to enter into the accommodating cavity through the air hole 111 and the communication hole 122a, and to cause damage to the display screen, in the embodiment of the present application, a waterproof air-permeable film 200 is arranged between the first end of the communication hole 122a close to the accommodating cavity and the accommodating cavity, under the action of the waterproof air-permeable film 200, it is ensured that the outside air can enter and exit the accommodating cavity, and at the same time, it can prevent the water vapor and impurities from entering the accommodating cavity.

[0020] Specifically, in the electronic device disclosed in the embodiment of the present application, the communication hole 122a can be directly communicated with the accommodating cavity, in this case, the waterproof air-permeable film 200 can be bonded to the end face of the communication hole 122a away from the air hole 111 by double-sided adhesive tape 400 or other materials, so as to ensure that the communication hole 122a can be isolated from the accommodating cavity, and at the same time, the connection stability between the waterproof air-permeable film 200 and the frame 100 is also relatively high. Of course, in the process of bonding the waterproof air-permeable film 200, the double-sided adhesive tape 400 needs to avoid the communication hole 122a to prevent the double-sided adhesive tape 400 from blocking the communication hole 122a. In other embodiments of the present application, the communication hole 122a can also be indirectly communicated with the accommodating cavity through other holes or slot structures, in this case, the waterproof air-permeable film 200 can be arranged on the above-mentioned hole or slot structure, and the details will be described below.

[0021] Further, in order to prevent the high-pressure water from flowing through the air hole 111 into the communication hole 122a and impacting the waterproof air-permeable film 200, as described above, the electronic device disclosed in the embodiment of the present application includes an elastic diaphragm 300, as the name implies, the elastic diaphragm 300 has elastic ability, and it is specifically used to provide a blocking effect. In a specific embodiment of the present application, the elastic diaphragm 300 can be formed of a material such as plastic having elastic ability, of course, it can also be formed by processing a metal material into a sheet-like structure, so as to form the elastic diaphragm 300 by using this metal structure having good elastic ability.

[0022] In one embodiment of the present application, the air vent hole 111 can extend along the length direction or the width direction of the electronic device to the side of the frame 100, and the communication hole 122a extends along the thickness direction of the display screen (or the electronic device), in which case, the extending directions of the air vent hole 111 and the communication hole 122a can be perpendicular to each other, of course, the communication hole 122a and the air vent hole 111 can be inclined relative to the aforementioned thickness direction. Based on this, an opening can be provided on the hole wall of the communication hole 122a, so that the communication hole 122a can communicate with the air vent hole 111 through the aforementioned opening. At the same time, in this case, the diameter of the air vent hole 111 can be greater than the diameter of the aforementioned opening, so as to ensure that the end surface of the frame 100 where the second end of the communication hole 122a is located has the condition of mounting the elastic diaphragm 300. Accordingly, the elastic diaphragm 300 can be mounted to the frame 100 away from the one end of the communication hole 122a through the air vent hole 111, and the elastic diaphragm 300 is located outside the communication hole 122a and towards the position of the air vent hole 111.

[0023] As described above, the air vent hole 111 and the communication hole 122a can both extend along a straight line direction, in which case, when the elastic diaphragm 300 is mounted outside the hole wall of the communication hole 122a from the air vent hole 111, the mounting difficulty of the elastic diaphragm 300 can be relatively small. Considering that in the case of the air vent hole 111 being a straight hole structure, if the high-pressure water flow impacts the air vent hole 111, the high-pressure water flow will directly impact the elastic diaphragm 300 along the air vent hole 111, which makes the impact degree of the high-pressure water flow on the elastic diaphragm 300 relatively large, and thus can cause the elastic diaphragm 300 to rebound, thereby adversely affecting the sealing effect between the elastic diaphragm 300 and the communication hole 122a.

[0024] In view of the above, in one embodiment of the present application, the air vent hole 111 can include a first hole section 111a and a second hole section 111b, the first hole section 111a and the second hole section 111b are in communication, and the second hole section 111b is in communication with the communication hole 122a, and in the electronic device disclosed in the embodiment of the present application, the axes of the first hole section 111a and the second hole section 111b are not collinear. In this case, even if the high-pressure water flow enters the electronic device from the first hole section 111a, when the high-pressure water flow flows to the second hole section 111b, due to the bent connection state of the first hole section 111a and the second hole section 111b, the overall flow speed of the high-pressure water flow can be effectively reduced, and the impact effect of the high-pressure water flow is reduced, in which case, it can be ensured that the high-pressure water flow can drive the elastic diaphragm 300 to produce elastic deformation, while basically not generating excessive impact force on the elastic diaphragm 300.

[0025] In the case where the air vent 111 includes the first hole section 111a and the second hole section 111b, the included angle between the axes of the first hole section 111a and the second hole section 111b can be appropriately reduced, or the length of the second hole section 111b can be appropriately reduced, and further, when the elastic diaphragm 300 is assembled, the elastic diaphragm 300 can still be installed into the position outside the hole wall of the communication hole 122a opposite to the second hole section 111b by using a micro mechanical hand or the like device.

[0026] In order to reduce the installation difficulty of the elastic diaphragm 300, in another embodiment of the present application, the frame 100 can include the frame body 110 and the support 120, the frame body 110 and the support 120 are separately formed, of course, either of the frame body 110 and the support 120 can be formed of metal or plastic or the like material, or both of the frame body 110 and the support 120 can include metal and plastic or the like material, which is not limited herein. In the case where the frame 100 includes the frame body 110 and the support 120, the support 120 can be a sheet or plate structure, and after the frame body 110 and the support 120 are respectively formed, the frame body 110 and the support 120 can be fixedly connected by using bonding or welding or the like.

[0027] In the above-mentioned embodiment of the present application, the display screen is arranged on one side of the frame body 110, and the display screen and the frame body 110 enclose the accommodation cavity, and the support 120 is arranged on the side of the frame body 110 facing the display screen. At the same time, the frame body 110 is provided with the air vent 111, and further, the frame body 110 can be provided with the first hole section 111a and the second hole section 111b. Correspondingly, the support 120 is provided with the communication hole 122a, and by designing the connection position and other parameters between the support 120 and the frame body 110, it can be ensured that after the support 120 and the frame body 110 are fixedly connected, the communication hole 122a on the support 120 can face the air vent 111 on the frame body 110 and communicate with the air vent 111, so that the elastic diaphragm 300 arranged between the communication hole 122a and the air vent 111 can block the high-pressure water flow entering through the air vent 111.

[0028] In the case where the above-mentioned technical solution is used, the elastic diaphragm 300 can be arranged in the frame body 110 at the position for installing the support 120, and then the support 120 is installed in the frame body 110 at the aforementioned position, so that the elastic diaphragm 300 can correspond to the communication hole 122a of the support 120, and it can be ensured that the elastic diaphragm 300 can form a mutually adhering relationship with the surface of the support 120 when subjected to an external force, so as to block the communication hole 122a. Obviously, in the embodiment of the present application, the installation difficulty of the elastic diaphragm 300 can also be reduced, and the cooperation precision between the elastic diaphragm 300 and the support 120 can be greatly improved, thereby improving the blocking effect of the elastic diaphragm 300 on the communication hole 122a.

[0029] The electronic device disclosed in the embodiments of the present application has a display screen arranged on one side of a frame 110, and the display screen can form a containing cavity together with the frame 110. A support 120 is arranged on the side of the frame 110 facing the display screen. The frame 110 is provided with a gas-permeable hole 111, and the support 120 is provided with a communication hole 122a. The gas-permeable hole 111 can communicate with the containing cavity through the communication hole 122a. A waterproof and gas-permeable film 200 is arranged between the first end of the communication hole 122a close to the containing cavity and the containing cavity. This can ensure that the containing cavity can exchange gas with the outside of the electronic device, and prevent water vapor from the outside from entering the containing cavity through the gas-permeable hole 111 and the communication hole 122a, and damaging the display screen and other devices.

[0030] Meanwhile, an elastic diaphragm 300 is arranged between the second end of the communication hole 122a close to the gas-permeable hole 111 and the gas-permeable hole 111. The elastic diaphragm 300 can be elastically deformed when subjected to an external force. Correspondingly, the elastic diaphragm 300 can restore its deformation when the external force is removed. Therefore, in the embodiments of the present application, the elastic diaphragm 300 has a first state and a second state. When the elastic diaphragm 300 is subjected to an external force, the elastic diaphragm 300 can switch from the second state to the first state, so that the elastic diaphragm 300 can be elastically deformed to block the communication hole 122a. Correspondingly, when the external force is removed, the elastic diaphragm 300 can restore its deformation, so that the communication hole 122a re-communicates with the gas-permeable hole 111.

[0031] Based on the above-mentioned electronic device disclosed in the present application, if high-pressure water flows into the electronic device through the gas-permeable hole 111, it will impact the elastic diaphragm 300 as an external force, causing the elastic diaphragm 300 to be elastically deformed, and further causing the elastic diaphragm 300 to block the communication hole 122a, thereby preventing the high-pressure water from flowing through the gas-permeable hole 111 into the communication hole 122a. This can prevent the high-pressure water from impacting the waterproof and gas-permeable film 200 between the end of the communication hole 122a away from the gas-permeable hole 111 and the containing cavity, ensuring that the electronic device has relatively good waterproof performance, and making the waterproof and gas-permeable film 200 have relatively strong persistence. Of course, when the high-pressure water no longer impacts the elastic diaphragm 300, i.e., when the external force acting on the elastic diaphragm 300 is removed, the elastic diaphragm 300 can restore its deformation, and further cause the communication hole 122a and the gas-permeable hole 111 to re-establish the state of mutual communication, ensuring that the gas-permeable hole 111 can still provide the containing cavity of the electronic device with the function of balancing air pressure.

[0032] It should be noted that in the above embodiment, the area of the end face of the second end of the through hole 122a in the bracket 120 that cooperates with the elastic diaphragm 300 cannot be a flat surface, that is, the bracket 120 has a non-flat area, and the aforementioned non-flat area cooperates with the elastic diaphragm 300, and accordingly, the aforementioned non-flat area surrounds the structure (such as the opening described above) disposed in the through hole 122a and in communication with the air vent hole 111.

[0033] In one specific embodiment of the present application, the aforementioned non-flat area can be a convex surface, that is, it is a structure that is high in the middle and low around the periphery as a whole, and in this case, when the elastic diaphragm 300 is acted upon by an external force, the peripheral edge thereof can be forced to adhere to the aforementioned convex surface, thereby causing the elastic diaphragm 300 to block the through hole 122a.

[0034] In another embodiment of the present application, the aforementioned non-flat area can be a concave surface, and in detail, the end face of the bracket 120 at the second end of the through hole 122a near the air vent hole 111 includes a concave avoidance surface 122b, and the concave avoidance surface 122b is disposed toward the air vent hole 111, and the elastic diaphragm 300 is disposed outside the concave avoidance surface 122b. As described above, the elastic diaphragm 300 can be elastically deformed, and in more detail, after the high-pressure water flow from the outside enters the electronic device through the air vent hole 111, the high-pressure water flow will impact the elastic diaphragm 300 to apply a force to the elastic diaphragm 300, and the elastic diaphragm 300 can be elastically deformed under the action of the external force, and then the elastic diaphragm 300 is pressed and deformed in the direction of the concave avoidance surface 122b, so that the elastic diaphragm 300 adheres to the concave avoidance surface 122b.

[0035] Similarly, in the process of forming the concave avoidance surface 122b, it is necessary to make the concave avoidance surface 122b surround the structure (such as the opening described above) disposed in the through hole 122a and in communication with the air vent hole 111, so that when the elastic diaphragm 300 adheres to the concave avoidance surface 122b, the elastic diaphragm 300 and the concave avoidance surface 122b form a surrounding adhesion area, and then the elastic diaphragm 300 can completely block the through hole 122a from the periphery of the aforementioned opening, achieving the purpose of isolating the through hole 122a and the air vent hole 111.

[0036] Obviously, in the case that the elastic diaphragm 300 and the avoidance concave surface 122b form a surrounding adhesion area, the high-pressure water flow in the air vent hole 111 cannot flow further into the communication hole 122a, thereby preventing the high-pressure water flow from impacting the waterproof and air-permeable membrane 200 between the end of the communication hole 122a away from the air vent hole 111 and the accommodation cavity, ensuring that the connection stability between the waterproof and air-permeable membrane 200 and the support 120 is always high, thereby preventing the electronic device from having a waterproof failure problem. Moreover, in the case of using the technical solution disclosed in the embodiments of the present application, the center area of the elastic diaphragm 300 that is relatively more stressed can be deformed relatively earlier in the direction of the avoidance concave surface 122b, and when the elastic diaphragm 300 is continuously impacted by the water flow, the elastic diaphragm 300 in a concave state as a whole can be used to guide the water flow, and at the same time, the water flow flows to the four corners of the elastic diaphragm 300, and flows to the end of the air vent hole 111 away from the communication hole 122a, on the one hand, it can promote the water flow to flow out of the air vent hole 111, and on the other hand, it can also prevent the water flow from entering the communication hole 122a from the adhesion gap between the elastic diaphragm 300 and the avoidance concave surface 122b.

[0037] Of course, as described above, the elastic diaphragm 300 has elastic ability and will produce elastic deformation when subjected to external force. Therefore, in the case that the aforementioned external force is removed, the elastic diaphragm 300 can recover the deformation, so that the elastic diaphragm 300 is no longer in adhesion with the avoidance concave surface 122b. In this case, the communication hole 122a and the air vent hole 111 can still communicate with each other, so that the elastic diaphragm 300 does not hinder the original balanced air pressure effect of the air vent hole 111.

[0038] In a specific embodiment of the present application, the avoidance concave surface 122b can be a spherical inner wall surface as a whole, and the avoidance concave surface 122b is arranged around the outer periphery of the aforementioned opening. Correspondingly, the elastic diaphragm 300 can be installed on the outside of the aforementioned opening. Of course, the coverage range of the elastic diaphragm 300 exceeds the range of the aforementioned opening, so as to ensure that the elastic diaphragm 300 can completely block the aforementioned opening. Moreover, in the case that the avoidance concave surface 122b adopts a spherical inner wall surface, a notch or the like can be arranged at the edge of the avoidance concave surface 122b, so as to ensure that the air vent hole 111 can communicate with the communication hole 122a through the gap between the outside of the elastic diaphragm 300 and the avoidance concave surface 122b before the elastic diaphragm 300 is elastically deformed, thereby ensuring that the air vent hole 111 can still normally provide the balanced air pressure effect.

[0039] As described above, the avoiding concave surface 122b can be a spherical inner wall surface structure. In order to further improve the fitting effect between the elastic diaphragm 300 and the avoiding concave surface 122b, in another embodiment of the present application, the avoiding concave surface 122b can be a cylindrical side surface or an approximately cylindrical side surface structure. More specifically, the avoiding concave surface 122b can have an axis, and the surface of the elastic diaphragm 300 facing the avoiding concave surface 122b can be parallel to the axis of the avoiding concave surface 122b. Meanwhile, the projection of the avoiding concave surface 122b in a plane perpendicular to the axis of the avoiding concave surface 122b is a smooth curve.

[0040] In other words, the avoiding concave surface 122b can be formed by continuously moving a smooth curve along a straight line direction, and the straight line direction is parallel to the surface of the elastic diaphragm 300 facing the avoiding concave surface 122b. It should be noted that the elastic diaphragm 300 is a sheet structure when not subjected to external force, and therefore the surface of the elastic diaphragm 300 is a plane. In addition, the smooth curve refers to a continuous and smooth curve without abrupt changes or sharp points.

[0041] In the case where the avoiding concave surface 122b adopts the above technical solution, when the elastic diaphragm 300 is impacted by high-pressure water flow, the region of the elastic diaphragm 300 facing the communicating hole 122a can be recessed to the side where the avoiding concave surface 122b is located, and the entire elastic diaphragm 300 can be curved, which makes the fitting effect of any position in the region where the elastic diaphragm 300 cooperates with the avoiding concave surface 122b relatively good.

[0042] As described above, the communicating hole 122a can extend along the thickness direction of the electronic device, and the extension direction of the air permeable hole 111 can be perpendicular to the extension direction of the communicating hole 122a. Accordingly, the waterproof and air permeable film 200 can be arranged at a position outside the hole wall of the communicating hole 122a facing the air permeable hole 111, so as to isolate the communicating hole 122a and the air permeable hole 111.

[0043] Further, along the extension direction of the communicating hole 122a, the cross-sectional area of the communicating hole 122a and the distance between the cross-section and the air permeable hole 111 can be proportional, that is, the cross-sectional area of the position of the communicating hole 122a farther away from the air permeable hole 111 can be larger. In this case, the communication area between the communicating hole 122a and the accommodating cavity can be relatively large, and the area of the region of the waterproof and air permeable film 200 arranged at the first end of the communicating hole 122a for gas exchange can be relatively large, which ensures that the efficiency of gas exchange between the accommodating cavity and the outside of the electronic device is relatively high, and further prevents the waterproof and air permeable film 200 from being easily burst open by gas due to sudden increase of external air pressure.

[0044] In the technical solution, the area of the port of the communication hole 122a close to one end of the air vent hole 111 is relatively small, so the size of the elastic diaphragm 300 is also relatively small, and the reliability of the sealing fit between the elastic diaphragm 300 and the communication hole 122a is relatively high. That is, in the embodiment, the port area of the first end of the communication hole 122a is greater than the port area of the second end of the communication hole 122a. Considering that the waterproof and breathable film 200 may not be directly attached to the end face of the communication hole 122a away from the air vent hole 111, in the embodiment, the communication area between the waterproof and breathable film 200 and the communication hole 122a is greater than the communication area between the air vent hole 111 and the communication hole 122a.

[0045] Further, without affecting the installation of other devices in the electronic device, the communication area between the waterproof and breathable film 200 and the communication hole 122a can be much greater than the communication area between the air vent hole 111 and the communication hole 122a. In this case, the area for gas exchange between the waterproof and breathable film 200 and the communication hole 122a can be further expanded, and the assembly stability of the waterproof and breathable film 200 and the reliability of the electronic device are relatively high.

[0046] To further improve the fit accuracy between the elastic diaphragm 300 and the recessed surface 122b, further, the elastic diaphragm 300 and the end face of the bracket 120 where the recessed surface 122b is located can be in adhesive fit. In this case, the assembly reliability between the elastic diaphragm 300 and the bracket 120 is relatively high, thereby further preventing the elastic diaphragm 300 from moving relative to the recessed surface 122b during assembly and operation of the electronic device, and ensuring that the elastic diaphragm 300 can provide reliable sealing for the communication hole 122a for a long time.

[0047] Specifically, the elastic diaphragm 300 and the end face where the recessed surface 122b is located can be fixedly connected by glue dispensing. To prevent the glue with relatively strong fluidity from flowing into the communication hole 122a during curing, thereby partially or completely sealing the communication hole 122a and affecting the normal operation of the air vent hole 111, in another embodiment, the elastic diaphragm 300 can be fixedly attached to the end face where the recessed surface 122b is located by the double-sided adhesive tape 400.

[0048] It should be noted that in the process of bonding the elastic diaphragm 300 and the support 120, only a small part of the elastic diaphragm 300 needs to be fixedly connected with the end face where the avoidance concave surface 122b is located, and the other part of the elastic diaphragm 300 is in a separable cooperation state with the end face where the avoidance concave surface 122b is located, so that the elastic diaphragm 300 which is in a bonding connection relationship with the aforementioned end face can still be elastically deformed when subjected to an external force, and the avoidance concave surface 122b forms a surrounding bonding area, thereby achieving the purpose of plugging the communication hole 122a.

[0049] More specifically, in the diameter direction of the second end port of the communication hole 122a, one end of the elastic diaphragm 300 can be fixedly connected with the end face where the avoidance concave surface 122b is located, and the other end of the elastic diaphragm 300 is provided as a free end, that is, the other end and the end face where the avoidance concave surface 122b is located do not form a bonding relationship, and they remain separable.

[0050] In addition, in order to improve the connection reliability between the elastic diaphragm 300 and the support 120, when bonding the elastic diaphragm 300, the bonding position between the elastic diaphragm 300 and the support 120 can be located outside the avoidance concave surface 122b, so as to prevent the elastic diaphragm 300 from being deformed to a certain extent before being subjected to an external force due to the mutual connection between the avoidance concave surface 122b in a curved surface structure and the elastic diaphragm 300, and thus weakening the plugging effect of the elastic diaphragm 300 on the communication hole 122a.

[0051] More specifically, the end face of the support 120 where the second end of the communication hole 122a close to the air hole 111 can further include a connecting surface, the connecting surface is located on one side of the avoidance concave surface 122b, and the connecting surface is a plane. In this case, one end of the elastic diaphragm 300 can be bonded to the connecting surface by the double-sided adhesive tape 400, which makes the stability of the positional relationship between the elastic diaphragm 300 and the avoidance concave surface 122b relatively better. In the case where the support 120 is provided with the above-mentioned connecting surface, by locating the connecting surface on the side of the avoidance concave surface 122b close to the air hole 111, the plugging reliability of the elastic diaphragm 300 can be further improved.

[0052] As described above, the elastic diaphragm 300 is arranged at the avoidance concave surface 122b, and optionally, the avoidance concave surface 122b can be perpendicular or parallel to the thickness direction of the display screen as a whole, in other words, if the avoidance concave surface 122b is approximately regarded as a plane, in the embodiments of the present application, the included angle α between the avoidance concave surface 122b and the straight line where the thickness direction of the display screen is located can be 0° or 90°.

[0053] In order to make the matching relationship between the elastic diaphragm 300 and the avoiding concave surface 122b relatively stronger in reproducibility, in an embodiment of the present application, the avoiding concave surface 122b can be arranged to be inclined relative to the thickness direction of the display screen, that is, the avoiding concave surface 122b is approximately regarded as a planar structure, and 0° < a < 90° can be made. At the same time, the structure of the frame body 110 can also be designed so that the side wall of the air hole 111 can also be designed corresponding to the end face where the avoiding concave surface 122b is located, and then the side wall of the air hole 111 is in a relative state with the avoiding concave surface 122b. In this case, by clamping the elastic diaphragm 300 between the avoiding concave surface 122b and the end face of the air hole 111 close to the communication hole 122a, the relative position between the elastic diaphragm 300 and the avoiding concave surface 122b can be relatively better, preventing the elastic diaphragm 300 from being displaced relative to the avoiding concave surface 122b due to the frequent impact of the high-pressure water flow on the elastic diaphragm 300, and adversely affecting the subsequent plugging effect of the elastic diaphragm 300. In addition, in the above embodiment, the air hole 111 can include a first hole section 111a and a second hole section 111b, in which case the avoiding concave surface 122b can be away from the end face where the port of the first hole section 111a is located towards the second hole section 111b.

[0054] As described above, the elastic diaphragm 300 can be adhesively fixed with the support 120, based on which, in the case that the avoiding concave surface 122b is arranged to be inclined relative to the thickness direction of the display screen, in the thickness direction of the display screen, one end of the elastic diaphragm 300 away from the display screen can be adhesively fixed with the support 120, and the other end of the elastic diaphragm 300 can be configured as a free end. In this case, when the high-pressure water flow impacts the elastic diaphragm 300, the matching relationship between the elastic diaphragm 300 and the avoiding concave surface 122b can be ensured to be more stable, and when the high-pressure water flow no longer continues to impact the elastic diaphragm 300, the position of the elastic diaphragm 300 after deformation is restored to be the same as its initial position, thereby ensuring that the subsequent plugging effect of the elastic diaphragm 300 is still relatively good.

[0055] As described above, the support 120 can be fixed to the side of the frame body 110 facing the display screen, in order to further improve the assembly stability between the support 120 and the frame body 110, the frame body 110 can be further provided with a sunken groove 112, and the sunken groove 112 is recessed in a direction away from the display screen, so that the sunken groove 112 can accommodate at least a part of the support 120, and then at least a part of the support 120 is embedded into the sunken groove 112, so that the sunken groove 112 provides a limiting action for the support 120, which can further improve the assembly stability between the support 120 and the frame body 110, and can also reduce the overall thickness of the electronic device at the position where the support 120 is located to a certain extent, thereby facilitating the development of the electronic device in the direction of lightness and thinness.

[0056] Meanwhile, the sink 112 is in communication with the air vent 111. As described above, the air vent 111 can extend inward from the side surface of the frame 110 to be in communication with the communication hole 122a. To this end, in the embodiment of the present application, the sink 112 can extend along the thickness direction of the electronic device, and by extending the air vent 111 inward from the outer side surface of the frame 110, it can be ensured that the sink 112 can be directly in communication with the air vent 111. Of course, in the embodiment of the present application, the air vent 111 can also include the first hole section 111a and the second hole section 111b. In this case, by making the extension direction of at least one of the first hole section 111a and the second hole section 111b have a component in the thickness direction of the electronic device, the setting depth of the sink 112 can also be appropriately reduced.

[0057] Of course, in the design process of the sink 112 on the frame 110, the position of the air vent 111 and the mounting position of the bracket 120 need to be designed to ensure that after the bracket 120 is embedded in the sink 112, the relief concave surface 122b on the bracket 120 can still be arranged opposite to the air vent 111, and ensure that the elastic diaphragm 300 mounted at the relief concave surface 122b can provide a blocking effect for the high-pressure water flow entering through the air vent 111.

[0058] More specifically, in the above-mentioned embodiment of the present application, the bracket 120 can be a sheet structure as a whole. For example, the air vent 111 is in communication with the bottom of the sink 112. The relief concave surface 122b can be arranged on the side end surface of the bracket 120 facing the bottom of the sink 112. Meanwhile, the extension direction of the communication hole 122a can be parallel to the recess direction of the sink 112, that is, the communication hole 122a can extend along the thickness direction of the display screen. Of course, the extension direction of the communication hole 122a can also have a first component and a second component. The first component is parallel to the thickness direction of the display screen, and the second component is perpendicular to the side surface where the air vent 111 is located. More intuitively, for example, the air vent 111 extends to the short side of the electronic device. The two opposite short sides are the length direction of the electronic device. Therefore, the extension direction of the communication hole 122a can be located in the plane formed by the length direction and the thickness direction of the electronic device, that is, the plane where the axis of the communication hole 122a is located is coplanar with the plane where the extension direction of the air vent 111 is located.

[0059] In the case of using the above technical solution, if a small amount of water vapor enters the communication hole 122a due to an accident, the water vapor will still have a certain impact effect on the waterproof and breathable membrane 200 located between the communication hole 122a and the accommodation cavity. In order to further improve the connection reliability between the waterproof and breathable membrane 200 and the bracket 120, in another embodiment of the present application, the plane where the axis of the communication hole 122a is located can intersect the plane where the axis of the air vent 111 is located.

[0060] In the technical solution, even if water vapor passes through the elastic diaphragm 300 and enters the communication hole 122a, since the communication hole 122a and the air permeable hole 111 are in a relative bending state, and the relative bending direction of the two has a component perpendicular to the direction of the axis of the air permeable hole 111, the flow speed of the water vapor entering the communication hole 122a can be greatly weakened, thereby greatly reducing the probability of connection failure of the waterproof and air permeable film 200.

[0061] Further, the direction of the axis of the communication hole 122a and the direction of the axis of the air permeable hole 111 can be perpendicular to each other, in which case, the gas exchange process between the communication hole 122a and the air permeable hole 111 is basically not hindered, and the flow speed of the water vapor entering the communication hole 122a through the air permeable hole 111 can be greatly weakened.

[0062] As described above, the communication area between the waterproof and air permeable film 200 and the communication hole 122a can be different from the communication area between the air permeable hole 111 and the communication hole 122a, so as to increase the area for gas exchange between the waterproof and air permeable film 200 and the communication hole 122a, in which case, taking the example that the waterproof and air permeable film 200 is attached to the end face of the communication hole 122a away from the air permeable hole 111, the side wall of the communication hole 122a can be a continuous curved surface, that is, the side wall of the communication hole 122a is in a closed ring structure as a whole except for the two end ports, in which case, on the one hand, the processing work of the communication hole 122a is facilitated, and on the other hand, the efficiency of gas entering and exiting the communication hole 122a is relatively high, and the stability of the gas exchange between the accommodation cavity and the outside is relatively good.

[0063] In the technical solution, the communication hole 122a can be formed in a manner similar to the injection molding process, so that the communication hole 122a is in a flared structure as a whole. In order to further reduce the processing difficulty of the communication hole 122a and the like, in another embodiment of the present application, a communication structure can be further arranged between the communication hole 122a and the accommodation cavity, and the waterproof and air permeable film 200 is correspondingly attached to the end face between the communication structure and the accommodation cavity.

[0064] In detail, in the case where the frame body 110 is provided with the above-mentioned sink 112, the support 120 can include a mounting portion 121 and a communication block 122, wherein the mounting portion 121 can be attached to one side of the frame body 110 facing the display screen, and the mounting portion 121 is arranged around the sink 112, and the waterproof and air permeable film 200 can be attached to one side of the mounting portion 121 facing the display screen, and the waterproof and air permeable film 200 covers the sink 112.

[0065] In order to enable the installation portion 121 to be arranged around the sink groove 112, the installation portion 121 can specifically be a ring-shaped structure, that is, a through structure is arranged in the central region thereof. In the case of adopting the above technical solution, the size of the sink groove 112 can be relatively large, and correspondingly, the size of the through structure in the installation portion 121 for avoiding the notch of the sink groove 112 can also be relatively large, and further, the communication area between the waterproof and breathable film 200 and the aforementioned through structure (or the notch of the sink groove 112) of the installation portion 121 is relatively large, which can ensure that the efficiency of the gas exchange of the waterproof and breathable film 200 is relatively high. Of course, in order to improve the sealing stability between the installation portion 121 and the frame 110, the two can be bonded by the double-sided adhesive tape 400, and a limiting groove 113 can be further arranged on the side of the sink groove 112 facing the display screen, the limiting groove 113 is arranged around the sink groove 112, and the installation portion 121 can be embedded in the limiting groove 113, and the side of the installation portion 121 facing the display screen can also be fixedly connected with the waterproof and breathable film 200 by the double-sided adhesive tape 400.

[0066] At the same time, in order to ensure that the waterproof and breathable film 200 can still communicate with the air holes 111, as described above, the support 120 further comprises a communication block 122, as shown in Figure 3 , Figure 4 and Figure 8 , the communication block 122 is fixed on the side of the installation portion 121 away from the display screen, and the communication block 122 is provided with an avoiding concave surface 122b and a communication hole 122a. By embedding the communication block 122 into the sink groove 112, the air holes 111 communicating with the sink groove 112 can communicate with the waterproof and breathable film 200 arranged at the notch of the sink groove 112 through the communication hole 122a on the communication block 122.

[0067] As described above, the size of the notch of the sink groove 112 and the through structure of the installation portion 121 can be relatively large, in this case, in order to prevent the air holes 111 from directly communicating with the sink groove 112, the communication block 122 can be used to isolate the air holes 111 and the notch of the sink groove 112 from each other. Specifically, the surface of the communication block 122 around the communication hole 122a can be attached to the corresponding region of the inner wall of the sink groove 112. More intuitively, as shown in Figure 4 , the installation portion 121 is located above the connecting block, in this case, the bottom wall of the communication block 122 can be attached to the bottom of the sink groove 112, and the rear side wall and the front side wall of the communication block 122 can be respectively attached to the inner wall of the sink groove 112, that is, the installation portion 121, the inner wall of the sink groove 112, the bottom wall of the sink groove 112 and the outer wall of the sink groove 112 can be respectively attached to the connecting block, so that the air holes 111 located on the left side of the connecting block are isolated from the right side of the communication block 122, and it is ensured that the air holes 111 can only communicate with the notch of the sink groove 112 through the communication hole 122a on the connecting block.

[0068] That is, in the embodiment of the present application, in the direction perpendicular to the recess direction of the sink 112, the communication block 122 can be embedded into one end of the sink 112 where the air vent hole 111 is located, and the communication hole 122a on the communication block 122 extends to the other end of the sink 112 to communicate with the sink 112, thereby ensuring that the air vent hole 111 can communicate with the waterproof and air-permeable film 200 at the opening of the sink 112 through the communication hole 122a.

[0069] As described above, in the case where the frame 100 includes multiple parts, the aforementioned multiple parts can be mutually attached, obviously, the scheme that the frame 100 in the above embodiment includes the frame body 110, the mounting part 121 and the connecting block conforms to the above case. For this purpose, in the embodiment of the present application, the connecting block and the side wall of the sink 112 in the frame body 110 can be mutually attached, in this case, the distance between any part in the area where the connecting block and the side wall of the sink 112 are mutually attached can be less than 0.05mm by designing the machining precision, which can basically prevent the water vapor in the air vent hole 111 from directly entering the sink 112 through the connecting block and the side wall of the sink 112 and impacting the waterproof and air-permeable film 200. Further, double-sided adhesive tape 400 can also be provided between the connecting block and the side wall of the sink 112, which can ensure that a reliable sealing connection relationship can be formed between the two.
