The waterproof component 3 is arranged inside the electronic device and embedded in the second groove 12, and the dustproof component 2 can be sealed in the first groove 11. Since the first groove 11 passes through the channel 13, the waterproof component 3 can play a waterproof role, preventing water from entering the channel 13 from the outside of the electronic device, and then preventing water from entering the inside of the electronic device from the first groove 11, which can improve the waterproof effect of the electronic device. In the embodiment of the present application, the dustproof component 2 can be first installed in the first groove 11, and then the waterproof component 3 can be installed in the second groove 12. The assembly process is simple, and the dustproof component 2 and the waterproof component 3 are firmly assembled with the frame 1, which can reduce the risk of the dustproof component 2 and the waterproof component 3 being separated from the frame 1, and can improve the reliability of dustproof and waterproof electronic equipment.

[0028] The hole-opening device 4 described in the embodiment of the present application includes but is not limited to devices that require holes such as speakers 41, receivers, microphones, and waterproof vents.

[0029] Specifically, the opening device 4 may be disposed inside the electronic device and may be connected to the frame 1 to achieve assembly between the opening device 4 and the frame 1 .

[0030] Specifically, the frame 1 is provided with a channel 13 extending in the first direction, one end of the channel 13 can be connected to the opening of the opening device 4, and the other end of the channel 13 can be connected to the outside of the electronic device, so that the channel 13 is used to transmit sound or gas passing through the opening. Taking the speaker 41 as an example, the opening can be a sound outlet hole, and the sound of the speaker 41 can be transmitted into the channel 13 through the sound outlet hole, and then transmitted out of the electronic device.

[0031] Specifically, the frame body 1 may also be provided with a first groove 11 and a second groove 12 that are connected. The first groove 11 and the second groove 12 are arranged sequentially along a second direction, and the second direction intersects with the first direction.

[0032] Furthermore, the thickness direction of the frame 1 is the thickness direction of the electronic device, and the thickness of the frame 1 is relatively thin, which is conducive to realizing the lightness and thinness of the electronic device.

[0033] Specifically, Figure 1 and Figure 2 As shown, the first groove 11 can be arranged in a vertical direction, and the second groove 12 can be arranged in a horizontal direction. Specifically, the dustproof component 2 can be embedded in the first groove 11, and the dustproof component 2 can be loosely matched with the first groove 11. The first groove 11 can limit the dustproof component 2, that is, limit the vertical placement of the dustproof component 2, and the dustproof component 2 can be vertically installed in the first groove 11 on the frame 1. Figure 3As shown, the dustproof component 2 is embedded in the first groove 11, and the waterproof component 3 is embedded in the second groove 12. The dustproof component 2 can be combined to form a T-shaped structure.

[0034] Specifically, the first groove 11 and the channel 13 can be connected, so that the first groove 11 can divide the channel 13 into a first channel 131 and a second channel 132, the first channel 131 can be connected to the outside of the electronic device, and the second channel 132 can be connected to the opening of the opening device 4. In this way, taking the speaker 41 as an example, under the dustproof effect of the dustproof component 2, dust outside the electronic device can be blocked from entering the second channel 132, and then dust can be prevented from entering the speaker 41, thereby improving the external performance of the speaker 41 and ensuring the electroacoustic performance of the electronic device.

[0035] Specifically, the sound of the speaker 41 can enter the second channel 132 through the sound outlet, and then enter the first channel 131 through the dustproof component 2, and then be transmitted to the outside of the electronic device. The dustproof component 2 in the embodiment of the present application can block dust and also transmit sound.

[0036] Specifically, the waterproof component 3 can be disposed inside the electronic device and embedded in the second groove 12, and the waterproof component 3 can be fixedly connected to the frame 1 to seal the dustproof component 2 in the first groove 11 to prevent the dustproof component 2 from being separated from the frame 1. Moreover, the waterproof component 3 can play a waterproof role, so that even if water outside the electronic device enters the first groove 11 through the first channel 131, it can be blocked by the waterproof component 3, thereby preventing water from entering the interior of the electronic device from the frame 1, and improving the waterproof effect of the electronic device.

[0037] Furthermore, during the assembly process, the dustproof component 2 can be first installed in the first groove 11, and then the waterproof component 3 can be fixed in the second groove 12, so that the dustproof component 2 and the waterproof component 3 can be assembled with the frame 1 at the same time. The assembly process is simple, and the dustproof component 2 and the waterproof component 3 are both embedded in the groove, which can reduce the risk of the dustproof component 2 and the waterproof component 3 being separated from the frame 1.

[0038] Alternatively, if Figure 1 As shown, the frame body 1 is provided with a second accommodating groove 16 and a third accommodating groove 17 which are connected. The notch of the second accommodating groove 16 is larger than the notch of the third accommodating groove 17. The second accommodating groove 16 and the third accommodating groove 17 are combined to form a stepped groove. The auxiliary screen 6 is embedded in the second accommodating groove 16 and is enclosed with the third accommodating groove 17 to form an internal space of the electronic device, and the internal space is used to place internal components of the electronic device, etc.

[0042] In the embodiment of the present application, the second groove section 112 is connected to the first channel 131 and the second channel 132 on both sides along the first direction, so that the dustproof component 2 can divide the channel 13 into the first channel 131 and the second channel 132. The second groove section 112 is connected to the first groove section 111 and the third groove section 113, and the first groove section 111 is connected to the second groove 12, so that the dustproof component 2 can be installed in the first groove 11.

[0043] Specifically, the first slot section 111 may be a through slot conducting along the second direction; the second slot section 112 may be a through slot conducting along the first direction and the second direction respectively; and the third slot section 113 may be a groove with a slot opening facing the second slot section 112 .

[0045] In the embodiment of the present application, the avoidance hole 221 is connected with the first channel 131 or the second channel 132, so that the middle area of ​​the dustproof net 21 can be connected with the first channel 131 and the second channel 132 respectively, which is convenient for the channel 13 to transmit sound or guide air, so that the dustproof net 21 can both block dust and pass sound.

[0046] Specifically, the center lines of the avoidance hole 221, the support plate 22 and the dustproof net 21 are nearly coincident, which facilitates the connection between the avoidance hole 221 and the first channel 131 or the second channel 132, and further facilitates the dustproof net 21 to connect the first channel 131 and the second channel 132.

[0047] Specifically, the dustproof net 21 may be a mesh net that can block dust and allow sound to pass through. The support plate 22 may be connected to the dustproof net 21 to support the dustproof net 21 and solidify the dustproof net 21. The support plate 22 may be a flat plate made of plastic, such as polyethylene terephthalate (PET).

[0048] Specifically, the avoidance hole 221 may be a circular hole or a square hole, etc. The size of the avoidance hole 221 may be set according to the size of the channel 13, and the embodiment of the present application does not specifically limit this.

[0049] Specifically, one side of the dustproof net 21 may be connected to the support plate 22 , or two opposite sides of the dustproof net 21 may be connected to the support plates 22 , respectively.

[0050] Optionally, the support plate 22 may be bonded and fixed to the dustproof net 21 by means of a double-sided adhesive tape 23 , which may improve the reliability of bonding between the support plate 22 and the dustproof net 21 .

[0051] Specifically, considering that glue overflow is likely to occur when using glue to fix the support plate 22 and the dustproof net 21, the embodiment of the present application uses double-sided tape 23 to bond the support plate 22 and the dustproof net 21, which can improve the reliability and stability of the assembled dustproof component 2.

[0052] Optionally, the shape of the double-sided tape 23 can be consistent with the shape of the support plate 22, so as to increase the bonding area between the support plate 22 and the dustproof net 21 and further improve the firmness of the bonding between the support plate 22 and the dustproof net 21.

[0053] Optionally, the width of the support plate 22 in the second direction is 0.6-1.0 mm, and the second direction is the thickness direction of the frame 1, which is convenient for reducing the thickness of the frame 1 and is conducive to achieving lightweight and thin electronic equipment.

[0054] Specifically, in the prior art, due to the IP68 waterproof requirement, the bonding width of the double-sided adhesive between the waterproof and dustproof component and the middle frame is L1=L2≥1mm, and the inclination angle of the middle frame is 40°~55°. The corresponding projection height of the double-sided adhesive in the thickness direction of the middle frame needs to be greater than (L1+L2)*sin(40°~55°), that is, the projection height of the double-sided adhesive in the thickness direction of the middle frame needs to be greater than 1.28~1.64mm. For the solution of this application, Figure 1 and Figure 2As shown, the double-sided tape 23 only provides the function of bonding the support plate 22 and the dustproof net 21. The projection height of the support plate 22 in the thickness direction of the frame 1 is less than or equal to 1.0 mm, and the corresponding projection height of the double-sided tape 23 in the thickness direction of the frame 1 is less than or equal to 1.0 mm, that is, H1+H2≤1.0, H1+H2 is less than (L1+L2)*sin(40°~55°). Therefore, compared with the prior art, the frame thickness in the embodiment of the present application can be thinner, which is convenient for the electronic device to achieve a lighter and thinner design.

[0056] In the embodiment of the present application, the sealing plate 31 is sealed and connected in the second groove 12, so as to achieve sealing and waterproofness at the notch where the second groove 12 communicates with the first groove 11, thereby preventing water from entering the interior of the electronic device.

[0057] Specifically, the sealing plate 31 may be a flat plate, and the material may be plastic, for example, a PET sheet.

[0058] Specifically, Figure 1 As shown, the sealing plate 31 is sealed and connected in the second groove 12 , so as to separate the first groove 11 from the third receiving groove 17 , thereby preventing water in the first groove 11 from entering the third receiving groove 17 through the second groove 12 .

[0059] Optionally, the waterproof component 3 may include a first waterproof glue 32; the sealing plate 31 is bonded to the second groove 12 by the first waterproof glue 32, which can improve the waterproof performance of the connection between the sealing plate 31 and the frame 1, thereby ensuring the waterproof performance of the electronic device.

[0061] Specifically, during the assembly process, the first waterproof glue 32 can be firstly filled in the annular groove 14 , and then the sealing plate 31 can be placed in the second groove 12 , so that the sealing plate 31 and the frame 1 can be bonded and fixed.

[0062] Specifically, the notch of the annular groove 14 and the notch of the second groove 12 are oriented in the same direction, and the annular groove 14 may be in the shape of a circular ring or a rectangular ring structure.

[0063] Optionally, the thickness of the sealing plate 31 in the second direction is 0.1-0.2 mm, and the second direction is the thickness direction of the frame 1, so that the thickness of the sealing plate 31 in the thickness of the frame 1 is relatively small, thereby facilitating the shortening of the thickness of the frame 1, which is beneficial to achieving lightweight and thin electronic equipment.

[0064] Specifically, in the prior art, the total height of the waterproof and dustproof assembly in the thickness direction of the middle frame is L, L>(L1+L2)*sin(40°~55°)+L3. Figure 1 and Figure 2 As shown, the thickness of the sealing plate 31 in the thickness direction of the frame 1 is H1. The total height of the dustproof component 2 and the waterproof component 3 in the thickness direction of the frame 1 is H, H = H1 + H2 + H3 + H4. Among them, L3 = H3, and (L1 + L2) * sin (40° ~ 55°) is greater than H1 + H2 + H4. Therefore, compared with the prior art, the frame thickness in the embodiment of the present application is thinner, and the electronic device is thinner and lighter.

[0065] Specifically, Figure 2 As shown, the thickness of the outer side of the frame body 1 protruding from the first groove 11 is H5, and H5 may be 0.15-0.25 mm, such as 0.2 mm.

In this way, after the annular protrusion 412 is buckled into the second channel 132, the annular protrusion 412 can be bonded and fixed to the frame 1 by the second waterproof glue 43, thereby realizing the installation and fixation between the speaker 41 and the frame 1, and also improving the waterproof effect of the connection between the speaker 41 and the frame 1.

[0075] Specifically, the second waterproof glue 43 can be UV glue. In this way, the UV glue can be first coated on the outer periphery of the annular protrusion 412. After the UV glue is cured, the annular protrusion 412 is squeezed into the second channel 132.
