Description

Technical Field

[0001] This application belongs to the technical field of communication equipment, and particularly relates to an electronic device. Background Art

[0002] In order to cope with relatively complex usage scenarios, the sealing performance of electronic devices is getting higher and higher. During the specific working process, the electronic components inside the electronic device will generate heat. After the overall sealing performance is improved, the internal air pressure of the electronic device increases, which will further lead to the inconsistency between the internal air pressure of the electronic device and the air pressure of the external environment of the electronic device, ultimately affecting the normal operation of the electronic device. Therefore, electronic devices generally need to increase air pressure balance holes to achieve internal and external air pressure balance.

[0003] Related technologies usually design air pressure balance holes and ventilation gaps in the electronic device, so that the inner cavity of the housing of the electronic device sequentially passes through the air pressure balance holes and the ventilation gaps and is connected to the external environment of the electronic device, thereby achieving the purpose of balancing air pressure. Considering the machining tolerances of structural parts and assembly deviations, the ventilation gaps may be eliminated after the components are assembled, which may further cause the air pressure balance holes to no longer be connected to the external environment of the electronic device through the ventilation gaps, and ultimately the internal and external air pressure balance cannot be achieved. Based on this, related technologies usually design another air pressure balance hole on the opposite sides of the components of the electronic device, so as to ensure that another ventilation gap formed on the opposite side of the components of the electronic device after assembly can be connected to the air pressure balance hole on the opposite side to ensure normal air pressure balance operation. However, this design requires more air pressure balance holes, so the structure of the components is relatively complex and the processing cost is also relatively high. Summary of the Invention

[0004] The present invention discloses an electronic device to solve the problem that the components of the electronic device in related technologies are prone to blockage and failure of the ventilation gap after assembly, and thus more air pressure balance holes need to be opened to ensure internal and external air pressure balance.

[0005] To solve the above technical problems, the present invention provides the following technical solutions:

[0006] An electronic device includes a first device component and a second device component. The second device component is provided with an air pressure balance hole, and the air pressure balance hole is communicated with the inner cavity of the electronic device.

[0007] The first device component has a first mating edge, and the second device component has a second mating edge. The curvatures of the first mating edge and the second mating edge are not equal.

[0008] When the first device component is installed on the second device component and the first mating edge abuts against the second mating edge, a ventilation gap is formed between a partial area of the first mating edge and a partial area of the second mating edge, and the ventilation gap communicates the air pressure balance hole with the external environment of the electronic device.

[0009] The technical solution adopted by the present invention can achieve the following technical effects:

[0010] The electronic device disclosed in the embodiment of the present application improves the structure of the electronic device in the related art, so that the curvatures of the first mating edge on the first device component and the second mating edge on the second device component are not equal. As a result, when the first mating edge and the second mating edge abut against each other, a ventilation gap can still be formed between their respective partial areas, avoiding the problem that the ventilation gap is eliminated due to the abutment of the first mating edge and the second mating edge when the first device component and the second device component of the electronic device in the related art are assembled, and thus being unable to balance the internal and external air pressures of the electronic device. At the same time, no matter how the first device component and the second device component are assembled, such a structure will not cause the first mating edge and the second mating edge to be unable to form a ventilation gap, so there is no need to open a large number of air pressure balance holes on the electronic device, which can ultimately reduce the number of air pressure balance holes of the electronic device and achieve the purpose of simplifying the structure of the corresponding components of the electronic device. Of course, since the number of air pressure balance holes can be reduced, the manufacturing cost of the corresponding components can be reduced accordingly. Description of the Drawings

[0025] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with specific embodiments of the present invention and the corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] The technical solutions disclosed in each embodiment of the present invention will be described in detail below in conjunction with the drawings.

[0027] Please refer to Figures 1 to 9 , an electronic device is disclosed in an embodiment of the present application. The disclosed electronic device includes a first device component 100 and a second device component 200.

[0028] Both the first device component 100 and the second device component 200 are peripheral components of the electronic device. After the electronic device is assembled, there is an assembly relationship between the first device component 100 and the second device component 200. Specifically, the second device component 200 can serve as the installation basis for the first device component 100. Optionally, the first device component 100 can be installed on the second device component 200 by fixing means such as bonding, snap connection, and connection by a connecting member.

[0029] The first device component 100 has a first mating edge 101, and the second device component 200 has a second mating edge 201. The curvatures of the first mating edge 101 and the second mating edge 201 are not equal. At least one of the first mating edge 101 and the second mating edge 201 is a curved edge.

[0030] In an embodiment of the present application, the second device component 200 is provided with an air pressure balance hole 210, and the air pressure balance hole 210 communicates with the inner cavity of the electronic device. When the first device component 100 is installed on the second device component 200 and the first mating edge 101 abuts against the second mating edge 201, a ventilation gap A is formed between a partial area of the first mating edge 101 and a partial area of the second mating edge 201. The ventilation gap A communicates the air pressure balance hole 210 with the external environment of the electronic device, thereby enabling the formation of an air pressure balance channel.

[0031] In an embodiment of the present application, the curvatures of the first mating edge 101 and the second mating edge 201 are not equal so that the first mating edge 101 and the second mating edge 201 can still form a ventilation gap A when they abut against each other. It should be noted that herein, the first mating edge 101 and the second mating edge 201 abut against each other, which means that after the first device component 100 is installed on the second device component 200, other parts of the first mating edge 101 and the second mating edge 201 except those enclosing the ventilation gap A are in a state of abutment. Since the curvatures of the first mating edge 101 and the second mating edge 201 are different, when the first mating edge 101 and the second mating edge 201 abut against each other, there are still non-contact areas between partial areas of the two, and thus the ventilation gap A can be formed. In this case, the inner cavity of the housing can be sequentially communicated with the external environment of the electronic device through the air pressure balance hole 210 and the ventilation gap A, and finally the internal and external air pressures of the electronic device are balanced.

[0032] Of course, it needs to be emphasized again that there are processing errors during the production of the components and assembly errors during the assembly. In an embodiment of the present application, when the first device component 100 and the second device component 200 are assembled, the width of the ventilation gap A is greater than the sum of the processing errors and assembly errors of the first device component 100 and the second device component 200. That is to say, even if there are processing errors and assembly errors of the first device component 100 and the second device component 200, the first mating edge 101 and the second mating edge 201 can still form a ventilation gap A communicating with the air pressure balance hole 210 even when they abut against each other.

[0033] The electronic device disclosed in the embodiments of the present application improves the structure of the electronic device in the related art, so that the curvature of the first mating edge 101 on the first device member 100 is not equal to the curvature of the second mating edge 201 on the second device member 200. As a result, an air-permeable gap A can still be formed when the first mating edge 101 and the second mating edge 201 are in contact with each other, avoiding the problem that the air-permeable gap is eliminated due to the contact between the first mating edge 101 and the second mating edge 201 when the first device member 100 and the second device member 200 of the electronic device in the related art are assembled, and thus the internal and external air pressures of the electronic device cannot be balanced. At the same time, no matter how the first device member 100 and the second device member 200 are assembled, such a structure will not cause the first mating edge 101 and the second mating edge 201 to fail to form an air-permeable gap, so there is no need to provide a large number of air pressure balance holes on the electronic device, which can ultimately reduce the number of air pressure balance holes of the electronic device and achieve the purpose of simplifying the structure of the corresponding components. Of course, since the number of air pressure balance holes can be reduced, the manufacturing cost of the corresponding components can be saved accordingly.

[0034] Of course, it should be added that when the first mating edge 101 and the second mating edge 201 do not come into contact with each other and are spaced apart (that is, all areas of the first mating edge 101 and the second mating edge 201 do not touch), it is easier to form an air-permeable gap A between some areas of the first mating edge 101 and some areas of the second mating edge 201. In this case, the width of the air-permeable gap A is larger, which is more conducive to achieving the balance of the internal and external air pressures of the electronic device.

[0035] In the embodiments of the present application, there can be various types of the first device member 100 and the second device member 200. For example, the electronic device may include a front shell, a frame, and a rear shell. The front shell can be fixed to the first side of the frame, and the rear shell can be fixed to the second side of the frame. The first side and the second side are opposite sides of the frame, and the rear shell and the frame are connected to form the inner cavity of the electronic device. The first device member 100 can be the front shell, and the second device member 200 can be the frame. For another example, the front shell can be fixed to the first side of the frame, and the rear shell can be fixed to the second side of the frame. The first side and the second side are opposite sides of the frame, and the front shell and the frame are connected to form the inner cavity of the electronic device. The first device member 100 is the rear shell, and the second device member 200 is the frame.

[0036] In other embodiments, the first device component 100 may include a first cover plate 120, and the first cover plate 120 may include a first mating edge 101. The first cover plate 120 may be a light-transmitting cover plate (such as a fill light cover plate, a display screen cover plate, etc.), or may be an opaque cover plate (such as a battery back cover), etc. The embodiments of the present application do not limit the specific type of the first cover plate 120. The second device component 200 is the housing of the electronic device. Since the housing is a basic component of the electronic device, taking the housing as the second device component 200 and opening the air pressure balance hole 210 thereon will not have a great impact on the overall strength of the electronic device. Further, the first cover plate 120 covers the air pressure balance hole 210, thereby preventing the air pressure balance hole 210 from being directly exposed.

[0037] In the embodiments of the present application, the housing may include a cover plate decorative ring 220. The first cover plate 120 is mounted on the cover plate decorative ring 220. The cover plate decorative ring 220 is also a part of the housing. The cover plate decorative ring 220 can provide an installation position for the first cover plate 120. The cover plate decorative ring 220 is disposed around the first cover plate 120 to protect the edge of the first cover plate 120, and at the same time can also restrain the first cover plate 120, thereby improving the stability of its installation. The edge of the first cover plate 120 surrounded by the cover plate decorative ring 220 may include a first mating edge 101, and the edge of the cover plate decorative ring 220 surrounding the first cover plate 120 may include a second mating edge 201. In this case, the second mating edge 201 is disposed outside the first mating edge 101. This structure can not only form a breathable gap between some regions of the two, but also the second mating edge 201 can enclose the first mating edge 101.

[0038] Specifically, the housing may further include a housing body 230, and the cover plate decorative ring 220 may be disposed on the housing body 230 to achieve installation. Of course, the air pressure balance hole 210 may be opened on the housing body 230.

[0039] Optionally, the first cover plate 120 may be fixed on the cover plate decorative ring 220 by means of adhesive bonding, so as to achieve installation on the cover plate decorative ring 220. Of course, the first cover plate 120 may also be fixed on the cover plate decorative ring 220 by means of snap connection. The embodiments of the present application do not limit the specific fixing method between the first cover plate 120 and the cover plate decorative ring 220. When the first cover plate 120 is a light-transmitting cover plate, the first cover plate 120 may be a plate-like structural member made of glass material, or may be a structural member made of other transparent materials (such as transparent resin material). The embodiments of the present application do not limit the specific material of the first cover plate 120.

[0040] In a further technical solution, the first cover plate 120 may have corners, and the corners may have a first arc-shaped side, and the first arc-shaped side forms a first mating edge 101. The portion of the cover plate decorative ring 220 opposite to the corners has a second arc-shaped side, and the second arc-shaped side forms a second mating edge 201. In this technical solution, the curvature of the second arc-shaped side is greater than the curvature of the first arc-shaped side. Further, when the two are in contact with each other, an air-permeable gap A is still formed between some regions of the two. This alternative solution can arrange the air-permeable gap A in the peripheral region where the corners are located. By changing the curvature of the edges of the corners, the size relationship between the curvature of the first arc-shaped side and the curvature of the second arc-shaped side can be changed, and thus the air-permeable gap A can be formed. Therefore, it has the advantage of being relatively easy to implement. Moreover, this way of forming the air-permeable gap A makes it easier for the air-permeable gap A to be formed at relatively concealed corners, which is beneficial to ensuring the appearance performance of the electronic device. At the same time, since both the first arc-shaped side and the second arc-shaped side are arc-shaped edges with a certain radian, changing the size relationship of their curvatures will not cause a large sense of disharmony in the visual effect.

[0041] As described above, the housing is provided with an air pressure balance hole 210. Based on this, in an alternative solution, the air pressure balance hole 210 may be opened within the area of the housing covered by the corners. This solution opens the air pressure balance hole 210 in the area of the housing covered by the corners of the first cover plate 120, making the air pressure balance hole 210 relatively close to the corners of the first cover plate 120. Further, the distance from the air pressure balance hole 210 to the air-permeable gap A can be reduced, which is beneficial to forming a shorter balance air passage and is beneficial to more quickly balancing the internal and external air pressures of the electronic device.

[0042] Of course, the air-permeable gap A can also be formed between the first cover plate 120 and other components. Based on this, in other embodiments, the first cover plate 120 may be provided with a through hole B. The electronic device may further include a camera decorative ring 400, and the camera decorative ring 400 is disposed in the through hole B. The edge of the camera decorative ring 400 forms a second mating edge 201, and the edge of the through hole B forms a first mating edge 101. The camera decorative ring 400 and the hole wall of the through hole B form the air-permeable gap A. In this case, by changing the curvature of the edge of the camera decorative ring 400 and / or the edge of the through hole B, a local area of the two can form the air-permeable gap A.

[0043] Of course, the through hole B may be adapted to the shape of the camera decorative ring 400. For example, the camera decorative ring 400 may be a square structural member, and correspondingly, the through hole B may be a square hole. For another example, the camera decorative ring 400 may be a circular structural member, and correspondingly, the through hole B may be a circular hole. The embodiments of the present application do not limit the specific shapes of the camera decorative ring 400 and the through hole B.

[0044] When the first mating edge 101 is formed at the edge of the through hole B and the second mating edge 201 is formed at the edge of the camera bezel 400, in an alternative solution, both the first mating edge 101 and the second mating edge 201 can be arc edges. The curvatures of the first mating edge 101 and the second mating edge 201 are different, and the central angle corresponding to the first mating edge 101 can be less than 10°. This structure can change the curvature by adjusting the curvature of the already arc-shaped edge, without causing a large sense of abruptness in the corresponding components, which is beneficial to the concealment design of the ventilation gap A.

[0045] Furthermore, when the through hole B is a circular hole and the camera bezel 400 is a circular structural member, due to the circular structure, the formation position of the ventilation gap A can be flexibly adjusted according to the actual requirements of different electronic devices, which is also beneficial to the flexibility of the layout of the air pressure balance hole 210.

[0046] As described above, when the first mating edge 101 is formed at the edge of the through hole B and the second mating edge 201 is formed at the edge of the camera bezel 400, both the first mating edge 101 and the second mating edge 201 can be arc edges. For the convenience of description, in this case, we define that the first mating edge 101 is the third arc edge and the second mating edge 201 is the fourth arc edge, and the curvature of the third arc edge is less than the curvature of the fourth arc edge. When the through hole B is a circular hole, the edge of the through hole B can further include a fifth arc edge. The two ends of the fifth arc edge are respectively connected to the two ends of the third arc edge, and the center of the fifth arc edge is concentric with the center of the fourth arc edge. This structure can form the ventilation gap A between the edge of the through hole B and the edge of the camera bezel 400, and at the same time, can ensure a good degree of fit between the through hole B and the camera bezel 400.

[0047] In another feasible embodiment, the camera bezel 400 can include a straight edge 401. The straight edge 401 is relatively easy to process, and the straight edge 401 forms the second mating edge 201, and the first mating edge 101 is an arc edge. In this case, the curvature of the second mating edge 201 approaches zero infinitely, and the curvature of the second mating edge 201 is much less than the curvature of the first mating edge 101. Since the curvature of the second mating edge 201 is almost zero, this structure can make it easier for the first mating edge 101 and the second mating edge 201 to form the ventilation gap A.

[0048] When the electronic device includes the camera bezel 400, the electronic device disclosed in the embodiment of the present application can further include a second cover plate 110. The second cover plate 110 is installed within the area surrounded by the camera bezel 400, so as to protect the lens of the camera of the electronic device.

[0049] In an alternative solution, there may be an assembly gap between the inner surface of the first device component 100 and the second device component 200, and the air pressure balance hole 210 can communicate with the ventilation gap A through the assembly gap. The assembly gap is a gap that naturally forms after the components are assembled. This structure makes full use of the assembly gap for communication without the need to specifically set up a connection structure, that is, without additional machining of a conduction structure, thereby simplifying the structure of the corresponding components.

[0050] In another feasible embodiment, the second device component 200 may be provided with a groove that can communicate with the air pressure balance hole 210. At least a part of the first device component 100 covers the notch of the groove and forms a connection channel, and the air pressure balance hole 210 communicates with the ventilation gap A through the connection channel. This structure is easy to form a relatively large conduction structure through the opening of the groove and the cooperation with the first device component 100, which is beneficial to achieving a better communication effect. At the same time, the setting of the groove can reduce the consumption of the cover decorative ring, thereby reducing costs.

[0051] In an alternative solution, a gasket may also be provided between the first device component 100 and the second device component 200. The gasket needs to avoid the air pressure balance hole 210, and a ventilation channel is reserved between the air pressure balance hole 210 and the ventilation gap A. The gas in the inner cavity of the electronic device can reach the ventilation channel through the air pressure balance hole 210, flow to the ventilation gap A through the ventilation channel, and finally enter the external environment, thereby achieving the purpose of air pressure balance.

[0052] As described above, the air pressure balance hole 210 can be covered with a breathable waterproof film 300. The breathable waterproof film 300 can achieve a good waterproof effect while not affecting the air pressure balance, thereby preventing liquid from entering the inner cavity through the ventilation gap A and the air pressure balance hole 210, and finally avoiding interference with the electronic components in the inner cavity.

[0053] The electronic device disclosed in the embodiments of the present application can be a mobile phone, a tablet computer, an e-book reader, a wearable device, etc. Of course, the electronic device disclosed in the embodiments of the present application can also be of other types. The embodiments of the present application do not limit the specific type of the electronic device.

[0054] In the above embodiments of the present invention, the differences between the various embodiments are mainly described. As long as the different optimized features of the various embodiments are not contradictory, they can be combined to form a more optimal embodiment. Considering the simplicity of the text, they will not be elaborated here.

[0055] The embodiments of the present invention have been described above in conjunction with the accompanying drawings. However, the present invention is not limited to the above specific embodiments. The above specific embodiments are merely illustrative rather than restrictive. Under the inspiration of the present invention, those of ordinary skill in the art can also make many forms without departing from the spirit of the present invention and the scope protected by the claims, and all of them fall within the protection scope of the present invention.
