Detailed Description

The following description of the technical solutions in the embodiments of the present disclosure will be made clearly and completely with reference to the accompanying drawings in the embodiments of the present disclosure, and it is apparent that the described embodiments are some embodiments of the present disclosure, but not all embodiments. Based on the embodiments in this disclosure, all other embodiments that a person of ordinary skill in the art would obtain without making any inventive effort are within the scope of protection of this disclosure.

Fig. 1 is a schematic view of a housing assembly provided in the related art. As shown in fig. 1, the housing assembly includes a middle frame 001, a light guide column 002 and a silica gel ring 003, wherein a through hole is formed in the middle frame 001, and the light guide column 002 is located in the through hole of the middle frame 001 and is used for transmitting light rays emitted by a light emitting device in the middle frame 001 to the outside of the middle frame 001. There is the space between the inner wall of leaded light post 002 and through-hole, and silica gel ring 003 links to each other with the outer wall of leaded light post 002 to be arranged in the space between the inner wall of leaded light post 002 and through-hole, thereby sealed the space between the inner wall of leaded light post 002 and through-hole, in order to improve housing assembly's waterproof performance. However, when the through hole is sealed by the silica gel ring 003 in the related art, because mutual friction exists between the silica gel ring 003 and the inner wall of the through hole, the contact area between the silica gel ring 003 and the inner wall of the through hole is small, and deformation is easy to occur, so that gaps can occur between the silica gel ring 003 and the inner wall of the through hole, the tightness of the shell assembly is reduced, and the waterproof and dustproof performances of the shell assembly are affected.

In order to improve the waterproof and dustproof performance of the housing assembly, the embodiment of the disclosure provides a housing assembly. Fig. 2 is a schematic cross-sectional view of a housing assembly provided in an embodiment of the present disclosure. As shown in fig. 2, the housing assembly includes a housing 1, a light guide 2, and a sealing member 3, wherein the housing 1 has a light guide hole 10, the light guide 2 is positioned in the light guide hole 10, and the sealing member 3 is injection molded between an outer wall of the light guide 2 and an inner wall of the light guide hole 10.

In the housing assembly provided by the embodiment of the disclosure, the sealing member 3 is injection molded between the inner wall of the light guide hole 10 and the outer wall of the light guide member 2, and intermolecular binding force exists between the sealing member 3 and the inner wall of the light guide hole 10 and between the sealing member 2, so that a gap between the inner wall of the light guide hole 10 and the light guide member 2 can be fully sealed. Compare in the mode through sealed light guide hole 10 of silica gel circle, sealing member 3 in this disclosed embodiment is difficult for warping, and has great area of contact between sealing member 3 and the inner wall and the light guide piece 2 of light guide hole 10, has better sealed effect, is favorable to improving the waterproof dustproof performance of casing subassembly.

In order to make the technical scheme and advantages of the present disclosure more apparent, embodiments of the present disclosure will be described in further detail below with reference to the accompanying drawings.

As shown in fig. 2, the housing assembly provided by the embodiment of the present disclosure includes a housing 1, a light guide 2, and a sealing member 3. The casing 1 is provided with a light guide hole 10, the light guide member 2 is positioned in the light guide hole 10, and the sealing member 3 is positioned between the outer wall of the light guide member 2 and the inner wall of the light guide hole 10. The sealing member 3 is formed between the outer wall of the light guide member 2 and the inner wall of the duct hole 10 by injection molding, thereby being in sealing connection with the light guide member 2 and the housing 1. Because a gap exists between the light guide member 2 and the hole wall of the light guide hole 10, the sealing member 3 can be injected into the light guide hole 10 through the gap and is connected with the light guide member 2 and the hole wall of the light guide hole 10 to realize sealing.

The sealing member 3 is illustratively liquid silicone, which is fluid at normal temperature. After heating at 80 degrees celsius for 30 minutes, the liquid silicone gel was cured, thereby completing the sealing of the light guide hole 10.

The light guide 2 is made of a transparent material, for example, a transparent plastic such as polycarbonate, and is not deformed at a temperature exceeding 130 degrees celsius, so that the structure of the light guide 2 is not affected by an excessively high temperature when the sealing member 3 is cured. Also, the housing 1 is made of a high temperature resistant material to avoid influencing the structure of the housing 1 due to excessive temperature when curing the sealing member 3.

In some embodiments of the present disclosure, as shown in fig. 2, the light guide 2 includes a light guide portion 21 and a connection portion 22, one end of the light guide portion 21 is connected to the connection portion 22, the light guide portion 21 is located in the light guide hole 10, and the connection portion 22 is located outside the light guide hole 10 and connected to the housing 1. The connecting portion 22 is used for connecting with the housing 1 to fix the light guiding portion 21 at the position of the light guiding hole 10, so that the light guiding portion 21 is located near the center of the light guiding hole 10, and the distance between the inner wall of the light guiding hole 10 and the light guiding portion 21 can be consistent as everywhere as possible, which is beneficial for filling the gap between the inner wall of the light guiding hole 10 and the light guiding portion 21 with the sealing member 3, and for fully sealing connection with the housing 1 and the light guiding member 2.

In some embodiments of the present disclosure, as shown in fig. 2, the housing 1 has a first surface 11 and a second surface 12 opposite to each other, the light guide hole 10 communicates the first surface 11 and the second surface 12, and the connection portion 22 is hermetically connected to the first surface 11. The light guiding portion 21 has a cylindrical shape, and a projection of an end of the light guiding portion 21 connected to the connecting portion 22 on the connecting portion 22 is located in an end face of the connecting portion 22, that is, the connecting portion 22 has a surface that abuts against the first surface 11.

Optionally, the housing 1 and the connecting portion 22 are adhered by a glue, and the glue is located between the first surface 11 and the connecting portion 22.

Alternatively, an end of the light guide 21 remote from the connection portion 22 forms a smooth surface with the second surface 12, thereby making the second surface 12 of the housing 1 relatively smooth.

In some embodiments of the present disclosure, as shown in fig. 2, the first surface 11 is provided with a flange 13, the flange 13 surrounding the light guiding hole 10, the flange 13 being connected to the connection portion 22. The provision of the flange 13 enables a gap to be formed between the connecting portion 22 and the first surface 11, and the seal 3 can enter between the connecting portion 22 and the first surface 11 and sealingly connect the connecting portion 22 and the first surface 11 of the housing 1 at the time of injection molding.

In some embodiments of the present disclosure, as shown in fig. 2, the housing 1 has a through hole 101, one end of the through hole 101 communicates with the inner wall of the light guide hole 10, and the other end of the through hole 101 communicates with the first surface 11. The through hole 101 is used for injection molding the sealing member 3 in the light guide hole 10, so that the difficulty in injection molding due to too small gap between the inner wall of the light guide hole 10 and the light guide member 2 is avoided.

It should be noted that, the projection of the connection portion 22 on the first surface 11 is not overlapped with the through hole 101, so as to avoid the connection portion 22 from closing the through hole 101.

Optionally, the seal 3 is also injection molded in the through hole 101. The seal 3 is also capable of sealing the through-hole 101 so as to avoid the through-hole 101 communicating with the light guide hole 10 from affecting the sealability of the housing assembly.

Fig. 3 is a schematic cross-sectional view of yet another housing assembly provided by an embodiment of the present disclosure. In some embodiments of the present disclosure, as shown in fig. 3, the housing assembly further includes a sealing ring 4, the sealing ring 4 is located between the light guiding portion 21 and the inner wall of the light guiding hole 10, and the communication between the through hole 101 and the light guiding hole 10 is located between the sealing ring 4 and the connection portion 22. The sealing ring 4 is located at one end of the light guiding portion 21 away from the connecting portion 22, and the sealing ring 4 is used for sealing a gap between the light guiding portion 21 and the light guiding hole 10, so that the sealing member 3 is prevented from flowing out from one end of the light guiding hole 10 away from the connecting portion 22 during injection molding. Moreover, the sealing ring 4 can also improve the tightness between the light guide member 2 and the inner wall of the light guide hole 10, thereby being beneficial to improving the waterproof and dustproof performances of the shell assembly.

In some embodiments of the present disclosure, as shown in fig. 3, the light guide 21 has a groove 23, and the sealing ring 4 is located in the groove 23. The groove 23 is used for accommodating the sealing ring 4, so that the sealing ring 4 is prevented from moving relative to the light guide member 2 in the process of mounting the light guide member 2 to the light guide hole 10, and the sealing ring 4 can be located at a preset position.

Fig. 4 is a schematic cross-sectional view of yet another housing assembly provided by an embodiment of the present disclosure. In some embodiments of the present disclosure, as shown in fig. 4, one end of the through hole 101 communicates with the inner wall of the light guide hole 10, and the other end of the through hole 101 communicates with the second surface 12. The configuration of the through hole 101 enables the seal 3 to be injection molded into the light guide hole 10 from the second surface 12 of the housing 1.

In some embodiments of the present disclosure, the housing assembly further includes a shield 6, as shown in fig. 4, the shield 6 being coupled to the second surface 12 and closing the light guide aperture 10. The shielding member 6 seals the gap between the light guide portion 21 and the light guide hole 10, and prevents the sealing member 3 from flowing out from the end of the light guide hole 10 away from the connection portion 22 during injection molding. The shutter 6 is detachably connected to the second surface 12 of the housing 1, and after injection molding is completed, the shutter 6 can be removed and the second surface 12 polished smooth.

The projection of the shutter 6 onto the second surface 12 is not coincident with the through hole 101, so as to avoid the shutter 6 closing the through hole 101.

In addition, the present disclosure also provides an electronic apparatus including the housing assembly and the light emitting device 5 in any of the above embodiments, the light emitting device 5 being opposite to the light guiding hole 10. The light emitting device 5 is mounted in the housing assembly on a side close to the first surface 11. The light emitting device 5 is electrically connected to the circuit board so that the light emission is controlled by the circuit board. The light emitting device 5 may be an infrared light emitter, the field angle of the light emitting device 5 being directed in the direction of the light guiding hole 10.

In the electronic device provided by the embodiment of the disclosure, the sealing member 3 is injection molded between the inner wall of the light guide hole 10 and the outer wall of the light guide member 2, and the intermolecular binding force exists between the sealing member 3 and the inner wall of the light guide hole 10 and between the sealing member 2, so that the gap between the inner wall of the light guide hole 10 and the light guide member 2 can be fully sealed. Compared with the sealing mode through the silica gel ring, the sealing piece 3 in the embodiment of the disclosure is not easy to deform, and the sealing piece 3 has a larger contact area with the inner wall of the light guide hole 10 and the light guide piece 2, so that the sealing effect is better, and the waterproof and dustproof performance of the electronic equipment is improved.
