DETAILED DESCRIPTION

[0033] In order to more clearly understand the above-mentioned purposes, features and advantages of the application, the application will be further described below. It should be noted that the embodiments of the application and the features in the embodiments can be combined with each other without conflict.

[0034] In the following description, many specific details are set forth in order to provide a thorough understanding of the application, but the application can also be implemented in other ways different from those described herein; Obviously, the embodiments in the description are only some of the embodiments of the application, not all the embodiments.

[0035] The mobile device will be described in detail below through specific embodiments:

[0036] Referring to Figure 1 And Figure 2 It is shown that some embodiments of the utility model provide a kind of mobile device, including middle frame 1.

[0037] Wherein, middle frame 1 surrounds and sets out the internal space 11 of mobile device and containing cavity 12, internal space 11 is embedded with internal part 3, opening 13 is set up on middle frame 1, opening 13 is communicated with containing cavity 12, card holder 5 can be inserted in containing cavity 12 through opening 13, to complete the installation of SIM card, opening 13 can also be used to accommodate cap 52 set on card holder 5, wherein gap is provided between cap 52 and middle frame 1 for air circulation.

[0038] When being specifically realized, first air permeable channel 14 is provided in middle frame 1, second air permeable channel 31 is provided on internal part 3, gap, containing cavity 12, first air permeable channel 14, second air permeable channel 31 and internal space 11 are sequentially communicated, second air permeable channel 31 is formed as the entrance of internal space 11, air can pass through gap, containing cavity 12, first air permeable channel 14, second air permeable channel 31 and enter internal space 11 through entrance from the outside of mobile device, that is, the inside and outside of mobile device can be communicated with each other, to realize internal and external air pressure balance.

[0039] Further, the sealing ring 4 is annularly arranged at the periphery of the communication position of the first air passage 14 and the second air passage 31, so as to realize the sealing between the middle frame 1 and the internal component 3 through the sealing ring 4, and prevent the problems such as air leakage and water seepage. The sealing ring 4 is arranged obliquely relative to the horizontal plane (that is, the view angle), which can increase the sealing width, improve the sealing performance, and strengthen the structural stability, and the sealing ring 4 is not easy to loosen and fall off, and is convenient for the subsequent assembly of the internal component 3. Figure 1

[0040] It should be noted that the internal space 11 forms an entrance for communicating the inside and outside of the mobile device, and other parts of the internal space 11 are closed. The electronic components are arranged in the internal space 11. Even if the electronic components heat and cause the internal air pressure to increase after working, the air can diffuse to the outside of the mobile device through the second air passage 31, the first air passage 14 and the gap, and then balance the internal and external air pressure.

[0041] The mobile device of the present application can share the same opening 13 with the accommodating cavity 12 through the first air passage 14, without the need to additionally open other air passages on the middle frame 1, which can improve the appearance performance of the mobile device.

[0042] Specifically, the internal component 3 is a mobile device internal structural component such as a loudspeaker box or a support, so as to realize the communication of the inside and outside of the mobile device by arranging the second air passage 31 on the internal component 3.

[0043] In some embodiments, as shown in FIG. 1, the first air passage 14 and the second air passage 31 are arranged in the thickness direction of the mobile device, and the through hole on the sealing ring 4 is a straight section 41. Figure 1

[0044] It can be understood that the sealing ring 4 is annular, and air or water can pass through the through hole in the middle of the sealing ring 4, and the sealing ring 4 can abut between the middle frame 1 and the internal component 3, so as to avoid air or water leaking from the gap between the middle frame 1 and the internal component 3, and improve the sealing performance.

[0045] Specifically, the inclined section 41 is arranged in the direction of being inclined relative to the horizontal plane, so as to communicate the first air passage 14 and the second air passage 31 arranged in the thickness direction of the mobile device. Compared with the straight section extending in the horizontal direction or the vertical direction, the cross-sectional size of the inclined section 41 is relatively large, the sealing effect of the sealing ring 4 arranged outside the inclined section 41 can be better, and the sealing effect can be ensured.

[0046] ​​In a specific implementation, the sealing ring 4 is a silica gel ring. After the middle frame 1 and the internal component 3 are assembled, the sealing ring 4 can be deformed and abutted between the middle frame 1 and the internal component 3, thereby having good sealing performance. Of course, the sealing ring 4 can also be attached to the middle frame 1 and the internal component 3 by double-sided adhesive tape, and the connection is relatively stable.

[0047] Referring to Figure 1 As shown in FIG. 1, a side surface of the middle frame 1 facing the internal component 3 is formed as a first inclined plane, and a side surface of the internal component 3 facing the middle frame 1 is formed as a second inclined plane. Specifically, the first inclined plane and the second inclined plane are inclined at the same angle in the same direction relative to a horizontal plane, that is, the first inclined plane and the second inclined plane are parallel to each other. Further, the first inclined plane and the second inclined plane are arranged in a spaced manner, and the sealing ring 4 is arranged in an inclined manner between the first inclined plane and the second inclined plane.

[0048] It can be understood that, continuing to refer to Figure 1 As shown in FIG. 1, when the mobile device is assembled, the sealing ring 4 is arranged on the first inclined plane, and then the internal component 3 is installed. During the installation of the internal component 3, the second inclined plane can be gradually pressed against a side of the sealing ring 4 away from the first inclined plane, thereby enhancing the structural tightness and further ensuring the sealing effect. During the installation process, the sealing ring 4 can be arranged between the middle frame 1 and the internal component 3 without using additional tools, thereby having a stable and reliable structure and being easy to operate.

[0049] In some embodiments, in the thickness direction of the mobile device, the first air passage 14 and the second air passage 31 are arranged between the card holder 5 and the rear cover 6 of the mobile device, thereby enabling the outside of the mobile device to communicate with an internal region between the card holder 5 and the rear cover 6 of the mobile device, so as to avoid an increase in internal air pressure due to an increase in temperature of the mobile device, thereby protecting the internal component 3 and improving safety performance.

[0050] Specifically, the first air passage 14 is arranged in an extending manner along a horizontal direction, and the second air passage 31 includes a first air sub-passage 311 and a second air sub-passage 312 connected in communication. The first air sub-passage 311 is arranged in an extending manner along the horizontal direction and is arranged in a staggered manner along the thickness direction with the first air passage 14. In this way, a drop can be formed between the first air passage 14 and the first air sub-passage 311, and the inclined section 41 can be arranged in an inclined manner and communicate the first air passage 14 and the first air sub-passage 311, that is, the inclined section 41 is arranged between the first air passage 14 and the first air sub-passage 311.

[0051] Further, the second air-permeable sub-channel 312 is arranged along the thickness direction and communicates with the entrance of the internal space 11, that is, the second air-permeable sub-channel 312 can form the entrance of the internal space 11 for balancing the internal and external air pressures. That is, air can pass through the gap, the accommodating cavity 12, the first air-permeable channel 14, the first air-permeable sub-channel 311 and the second air-permeable sub-channel 312 from the outside of the mobile device to the internal space 11 through the entrance, so that the inside and outside of the mobile device can be communicated with each other to balance the internal and external air pressures.

[0052] Of course, it should be noted that the first air-permeable channel 14 and the second air-permeable channel 31 can also be air-permeable channels of other shapes, and the present application does not limit this, as long as the inclined section 41 can be formed between the first air-permeable channel 14 and the second air-permeable channel 31 to increase the sealing width and improve the sealing performance.

[0053] In some embodiments, the end of the second air-permeable channel 31 away from the first air-permeable channel 14 is provided with a waterproof air-permeable film 2, which can prevent water from entering the mobile device through this channel to ensure that the internal space 11 is dry. It can be understood that almost all electronic components of the mobile device, such as CUP and GPU, are arranged in the internal space 11. The waterproof air-permeable film 2 can effectively prevent water from entering and avoid damaging the electronic components, thereby ensuring the service life of the mobile device. At the same time, the waterproof air-permeable film 2 can also enable the gas inside and outside the mobile device to communicate with each other to balance the internal and external air pressures.

[0054] In specific implementation, the surface of the inner member 3 is recessed to form a mounting groove 33, and the end of the second air-permeable channel 31 away from the first air-permeable channel 14 is connected to the bottom wall of the mounting groove 33 to realize the communication between the second air-permeable channel 31 and the internal space 11 of the mobile device through the mounting groove 33.

[0055] Specifically, the waterproof air-permeable film 2 is arranged in the mounting groove 33, and the waterproof air-permeable film 2 is lower than or flush with the plane where the slot of the mounting groove 33 is located, that is, the surface of the waterproof air-permeable film 2 does not exceed the plane where the slot of the mounting groove 33 is located, so as to avoid the waterproof air-permeable film 2 from causing additional interference and influence on the internal space 11 of the mobile device.

[0056] In some embodiments, the mobile device further includes a card holder 5 and a sealing rubber ring 51 arranged around the card holder 5. The sealing rubber ring 51 is in abutting cooperation with the inner wall of the accommodating cavity 12 to realize the sealing of the opening 13 and the internal space 11 through the sealing rubber ring 51. It can be understood that the internal space 11 of the mobile device includes not only the space where electronic components exist, but also the space for balancing the internal and external air pressures. By arranging the sealing rubber ring 51, water can be prevented from entering the internal space of the mobile device through the opening 13 and the accommodating cavity 12 to cause damage to the electronic components such as the SIM card.

[0057] Further, the first air passage 14 is arranged at the side of the sealing rubber ring 51 close to the opening 13. It can be understood that the air and water entering the interior of the mobile device through the opening 13 can enter the interior space 11 from the first air passage 14 without passing through the side of the sealing rubber ring 51 far from the opening 13, so that the air pressure balance between the interior and the exterior of the mobile device can be achieved while ensuring the waterproof of the specific area.

[0058] It can be understood that the sealing rubber ring 51 is arranged on the card holder 5, and the sealing rubber ring 51 can divide the containing cavity 12 into two parts, one part is located at the side of the sealing rubber ring 51 close to the opening 13 and communicates with the first air passage 14, so that the air passage communicating the interior and the exterior of the mobile device is formed at the side of the sealing rubber ring 51 close to the opening 13 to balance the air pressure between the interior and the exterior; the other part is located at the side of the sealing rubber ring 51 far from the opening 13 and communicates with the interior space 11, so that the interior space 11 is closed by the sealing rubber ring 51, and there is only one entrance to the interior space 11 through the second air passage 31, and the waterproof air permeable film 2 is arranged at the entrance to achieve waterproof at the only one entrance and protect the internal electronic components.

[0059] In specific implementation, the sealing rubber ring 51 and the card holder 5 are integrally injection molded. Specifically, the sealing rubber ring 51 can be injection molded on the card holder 5 in liquid state to improve the structural stability of the card holder 5.

[0060] In some embodiments, referring to Figure 2 It is shown that the end of the second air passage 31 far from the first air passage 14 leads to the top surface of the inner part 3, and forms an air vent 32 on the top surface of the inner part 3, referring to Figure 3 It is shown that the top surface of the inner part 3 at the periphery of the air vent 32 forms a first sealing surface 34, the air vent 32 communicates with the entrance of the interior space 11, and the interior and the exterior of the mobile device communicate through the air vent 32 and the entrance. Further, the outer surface of the middle frame 1 on the same side as the first sealing surface 34 forms a second sealing surface 15.

[0061] When the mobile device is subjected to the semi-whole machine air tightness test, the air tightness test fixture can form a sealed space between the first sealing surface 34 and the second sealing surface 15 by covering the first sealing surface 34 and the second sealing surface 15, and the sealed space is the space of the interior space 11 for balancing the air pressure between the interior and the exterior, the air in the sealed space is extracted by the air tightness test equipment, so that the air pressure difference between the interior and the exterior of the mobile device is formed, and then the leakage value set by the air tightness test equipment is used to determine whether the semi-whole machine has leakage problem.

[0062] It can be understood that when the air tightness test fixture covers the first sealing surface 34, the air vent 32 formed on the top surface of the inner part 3 directly facing the human body can be blocked, which is convenient for operation and compared with the air vent 32 in other positions, the air tightness of the mobile device can be detected conveniently.

[0063] In some embodiments, with reference to Figure 4 As shown, the outer surface of the middle frame 1 located at the periphery of the opening 13 is formed as the third sealing surface 16.

[0064] In specific implementation, when the air tightness of the mobile device is tested, the air tightness test fixture covers the third sealing surface 16, thereby isolating the internal and external space of the mobile device, and then the air in the internal space of the mobile device is extracted by the air tightness test device, so that the air pressure difference between the internal and external space of the mobile device is formed, and then whether the mobile device has a leakage problem is determined by the leakage value set by the air tightness test device.
