DETAILED DESCRIPTION

[0049] In order to make the purpose, features, and advantages of the present disclosure more obvious and easy to understand, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present disclosure.

[0050] See also Figure 1An embodiment of the present disclosure provides an electronic device, which includes a housing 1 and a light guide 2, wherein the light guide 2 is used to transmit light emitted by a light source 3 in the housing 1 to the outside of the housing 1.

[0051] See also Figure 1 The housing 1 includes a first housing 11 and a first second housing 12. The first second housing 12 is connected to the first housing 11, and an assembly space is formed between the first second housing 12 and the first housing 11. The assembly space can be used to install components such as the motherboard 4 and the power supply. The first second housing 12 includes a chamber 13 and a first structure 14, and the assembly space is connected to the outside through the chamber 13.

[0052] See also Figure 1 and Figure 2 The light guide 2 includes a second structure 21, an incident surface and an exit surface. The light guide 2 is arranged in the chamber 13. The exit surface is exposed to the outside of the first shell 12 through the chamber 13. The light guide 2 is used to transmit the light incident from the incident surface and emit it from the exit surface. There is a first state and a second state between the first structure 14 and the second structure 21. The first structure 14 and / or the second structure 21 are converted between the first state and the second state through elastic deformation.

[0053] In the first state, the first structure 14 and the second structure 21 are combined to fix the light guide 2 in the chamber 13;

[0054] In the second state, the first structure 14 and the second structure 21 are not combined, so that the light guide 2 can slide into the cavity 13 or slide out of the cavity 13 .

[0055] The light guide 2 is arranged in the chamber 13, and has a good light-shielding effect, which can reduce the use of light-shielding auxiliary materials. In the second state, at least one of the first structure 14 and the second structure 21 undergoes elastic deformation, and the light guide 2 can slide into the chamber 13. When the light guide 2 is located at the target position in the chamber 13, the elastically deformed first structure 14 and the second structure 21 return to their original state, and the first structure 14 and the second structure 21 are combined to fix the light guide 2 to the first shell 12.

[0056] In a first state in which the first structure 14 and the second structure 21 are combined to fix the light guide 2 in the chamber 13, external force is applied to elastically deform at least one of the first structure 14 and the second structure 21, thereby releasing the interaction between the first combination and the second structure 21 so that the two are not combined, and the light guide 2 can slide out of the chamber 13.

[0057] Of course, the light guide 2 can also slide into the chamber 13 through elastic deformation of at least one of the first structure 14 and the second structure 21, and when located at the target position in the chamber 13, the first structure 14 and the second structure 21 return to their original state so that the two can be combined to fix the light guide 2 to the first and second shells 12. Without damaging the first and second shells 12, the light guide 2 cannot slide out of the chamber 13.

[0058] The light guide 2 is fixed to the housing 1 by combining the first structure 14 and the second structure 21 capable of elastic deformation, without the need for a hot melt process, which not only reduces the cost of the hot melt process but also avoids damage to adjacent structures caused by the hot melt process.

[0059] In one embodiment, see Figure 3 The first second housing 12 includes a main body 121 and a side wall 122. The side wall 122 is arranged at the edge of the main body 121, and the side wall 122 and the main body 121 meet the vertical condition. If the angle between the side wall 122 and the main body 121 is within the first angle range, the side wall 122 and the main body 121 meet the vertical condition. The first angle range can be, for example, 85°-95°.

[0060] The chamber 13 is opened on the side wall 122, and the light guide 2 transmits the light emitted by the light source 3 in the assembly space from the side of the shell 1 to the outside of the shell 1. The first inner wall surface 131 of the chamber 13 and the inner surface of the main body 121 meet a coplanar relationship, and the first inner wall surface 131 is the inner wall surface of the chamber 13 on the side close to the main body 121. The height difference between the first inner wall surface 131 of the chamber 13 and the inner surface of the main body 121 is not greater than the first threshold, and the first inner wall surface 131 of the chamber 13 and the inner surface of the main body 121 meet a coplanar relationship, and the first threshold can be 2mm, for example. When the height difference between the first inner wall surface 131 of the chamber 13 and the inner surface of the main body 121 is 0mm, 1mm, 1.5mm, etc., which is not greater than 2mm, the first inner wall surface 131 of the chamber 13 and the inner surface of the main body 121 meet a coplanar relationship. The first inner wall surface 131 of the cavity 13 and the inner surface of the main body 121 are coplanar, so that the light guide 2 can slide into the cavity 13 along the inner surface of the main body 121 , which facilitates the assembly of the light guide 2 and the housing 1 .

[0061] In one embodiment, see Figure 1 and Figure 2 , the corresponding first structure 14 and second structure 21 are combined, including the first structure 14 and second structure 21 being engaged. In a specific implementation, one of the first structure 14 and second structure 21 is a hook or a block, and the other is a slot 145. When the light guide 2 slides into the chamber 13, the first structure 14 and / or the second structure 21 can be elastically deformed so that the light guide 2 can move to the target position, and the hook or block is combined with the slot 145 to fix the light guide 2 and the first and second shells 12.

[0062] In one embodiment, see Figures 4 to 6 The first structure 14 includes a first strip hole 141, a second strip hole 142 and a third strip hole 143. The first strip hole 141, the second strip hole 142 and the third strip hole 143 are all arranged on the first inner wall surface 131 and penetrate the main body 121. The second strip hole 142 and the third strip hole 143 are arranged at two ends of the first strip hole 141 opposite to each other. One end of the second strip hole 142 is connected to one end of the first strip hole 141, and one end of the third strip hole 143 is connected to the other end of the first strip hole 141. The portion surrounded by the third strip hole 143, the first strip hole 141 and the second strip hole 142 forms a tongue 144. The second structure 21 includes a first clamping block 211. The first clamping block 211 is protrudingly arranged on the first surface of the light guide 2. In the first state, the first clamping block 211 is embedded in the first strip hole 141 to fix the light guide 2 in the chamber 13. In the second state, the tongue piece 144 generates elastic deformation, so that the light guide 2 can slide into the chamber 13, or slide out of the chamber 13. When the light guide 2 slides into the chamber 13, the light guide 2 squeezes the tongue piece 144, and the tongue piece 144 bends. When the light guide 2 moves to the target position, the first block 211 is embedded in the first strip hole 141, and the free end of the tongue piece 144 acts on the first block 211 to prevent the light guide 2 from exiting the chamber 13. The wall surface of the first strip hole 141 opposite to the tongue piece 144 acts on the first block 211 to prevent the light guide 2 from continuing to slide forward. The tongue 144 formed on the main body 121 by the third strip hole 143, the first strip hole 141 and the second strip hole 142 passing through the main body 121 is easy to undergo elastic deformation when the light guide 2 slides into the chamber 13, and when the light guide 2 moves to the target position, the tongue 144 returns to its original position and presses the first block 211 located in the first strip hole 141.

[0063] The length direction of the first strip hole 141 satisfies the perpendicular condition to the center line of the chamber 13. The light guide 2 slides into the chamber 13 along the center line of the chamber 13, or slides out of the chamber 13. The included angle between the length direction of the first strip hole 141 and the center line of the chamber 13 is within the second angle range, and the length direction of the first strip hole 141 and the center line of the chamber 13 meet the perpendicular condition. The second angle range may be, for example, 85°-95°.

[0064] The length direction of the second strip hole 142 and the length direction of the third strip hole 143 respectively meet the parallel condition with the center line of the chamber 13. The angle between the length direction of the second strip hole 142 or the length direction of the third strip hole 143 and the center line of the chamber 13 is within the third angle range, and the length direction of the second strip hole 142 or the length direction of the third strip hole 143 and the center line of the chamber 13 meet the parallel condition. The third angle range can be, for example, 0°-10°. In an exemplary embodiment, the angle between the length direction of the second strip hole 142 and the center line of the chamber 13 is within the range of 0°-10°, and the length direction of the second strip hole 142 and the center line of the chamber 13 meet the parallel condition. The angle between the length direction of the third strip hole 143 and the center line of the chamber 13 is within the range of 0°-10°, and the length direction of the third strip hole 143 and the center line of the chamber 13 meet the parallel condition.

[0065] The second bar-shaped hole 142 includes a first end and a second end, the first end is connected to the first bar-shaped hole 141, and the second end is far away from the outside of the shell 1 relative to the first end. The third bar-shaped hole 143 includes a third end and a fourth end, the fourth end is connected to the first bar-shaped hole 141, and the fourth end is far away from the outside of the shell 1 relative to the third end.

[0066] The second end and the third end extend to the outside of the cavity 13 respectively. The second end and the third end extend to the outside of the cavity 13 respectively so that the tongue piece 144 is partially located outside the cavity 13. When the light guide 2 slides into the cavity 13, the tongue piece 144 can be elastically deformed in time and assembled into the cavity 13 using the light guide 2.

[0067] See also Figure 7 The first block 211 has a first guide surface 212 , and the first guide surface 212 can make the light guide 2 easy to slide into the chamber 13 .

[0068] In one embodiment, see Figure 5 The first structure 14 includes a slot 145, which is disposed on the second inner wall surface 132 of the chamber 13, and the second inner wall surface 132 is opposite to the first inner wall surface 131; see Figure 7 The second structure 21 includes a second block 213, and the second block 213 is convexly disposed on the second surface of the light guide 2; see Figure 1 and Figure 2 In the first state, the second clamping block 213 is embedded in the clamping groove 145 to fix the light guide 2 in the chamber 13. When the light guide 2 slides into the chamber 13, the second clamping block 213 is elastically deformed under the interaction with the second wall surface. When the light guide 2 moves to the target position, the second clamping block 213 is embedded in the clamping groove 145, and the force acting on the second clamping block 213 disappears. The second clamping block 213 restores its original shape and combines with the clamping groove 145 to fix the light guide 2 to the first second housing 12.

[0069] The second block 213 has a second guiding surface, and the second guiding surface can make the light guide 2 slide into the chamber 13 easily.

[0070] The matching first structure 14 and second structure 21 may include only the first card block 211 and the corresponding tongue piece 144 structure, or only the second card block 213 and the corresponding slot 145, or both the first card block 211 and the corresponding tongue piece 144 structure and the second card block 213 and the corresponding slot 145.

[0071] In one embodiment, see Figure 4 The side wall 122 includes a first portion 17 and a second portion 18 adjacent to each other. The cavity 13 is disposed in the first portion 17. Along the extension direction of the cavity 13, the thickness of the first portion 17 is greater than the thickness of the second portion 18. The cavity 13 is disposed in the first portion 17, so that the cavity 13 has a larger depth dimension, and the light guide 2 can be basically accommodated in the cavity 13 without adding additional light-shielding auxiliary materials.

[0072] In one embodiment, see Figure 4 The first part 17 has a first hooking structure 15 on the top surface, and the first housing 11 has a corresponding second hooking structure. The first hooking structure 15 and the second hooking structure are used to cooperate with each other so that the first housing 11 and the first second housing 12 are positioned relative to each other. The first part 17 is provided with a chamber 13 and a first hooking structure 15 for connecting with the first housing 11. By integrating the chamber 13 and the first hooking structure 15 in the first part 17, the structure of the housing 1 and the assembly space inside the housing 1 can be fully utilized, the occupation of the assembly space can be reduced, and the electronic device components can be compacted.

[0073] The first hooking structure 15 and the second hooking structure are used for mutual positioning between the first shell 11 and the first second shell 12. When the first shell 11 and the first second shell 12 are buckled, the first hooking structure 15 and the second hooking structure cooperate with each other to position the first shell 11 and the first second shell 12, thereby improving the firmness of the connection between the first shell 11 and the first second shell 12. In a specific implementation, one of the first hooking structure 15 and the second hooking structure can be a positioning groove, and the other can be a positioning strip adapted to the positioning groove. When the first shell 11 and the first second shell 12 are buckled, the positioning strip is embedded in the positioning groove to position the first shell 11 and the first second shell 12.

[0074] In one embodiment, see Figure 7The light guide 2 includes a conducting part and an output part, the incident surface is arranged on the conducting part, the output part is connected to the conducting part, the emission surface is arranged on the output part, and the cross section of the output part is smaller than the cross section of the conducting part; the chamber 13 includes a receiving part and an emission part 22, the cross section of the emission part 22 is smaller than the cross section of the receiving part, the receiving part is used to receive the conducting part, and the emission part 22 is used to receive the output part. The cross section of the emission part 22 is smaller than the cross section of the receiving part, so that the conducting part located in the receiving part can be limited on one side of the emission part 22, and the light guide 2 is fixed in the chamber 13.

[0075] In one embodiment, see Figure 2 The first and second shells 12 include a first shell 123 and a second shell 124. The accommodating portion is disposed on the first shell 123, and the material of the first shell 123 is plastic. The second shell 124 is covered on the outer surface of the first shell 123, and the output portion is disposed on the second shell 124, and the material of the second shell 124 is metal. The first and second shells 12 are made of plastic material, which can form a structure for connecting with the first shell 11 and a structure for assembling components such as the motherboard 4. The second shell 124 is made of metal material, which can enhance the appearance and texture of the electronic device.

[0076] In the embodiment of the present disclosure, the light guide 2 can be placed in the accommodation portion first, and then the second shell 124 can be connected to the first shell 123. The second shell 124 can limit the output portion, thereby fixing the light guide 2 in the chamber 13. The light guide 2 can be placed in the accommodation portion from the outside of the first shell 123, or from the inside of the first shell 123.

[0077] A side where the first shell 11 and the first second shell 12 are connected has an oblong hole 16 , and the oblong hole 16 is connected to the accommodating portion.

[0078] In one embodiment, see Figure 7 The emitting portion 22 is a cylinder, and the emitting surface is arranged on the end surface of the cylinder.

[0079] In one embodiment, see Figure 1 The electronic device further includes a mainboard 4 and a light source 3. The mainboard 4 is arranged in the assembly space; the light source 3 is arranged on the mainboard 4, and the light source 3 corresponds to the incident surface. The light guide 2 can transmit the optical light emitted by the light source 3 to the outside of the housing 1. The light source 3 can be a light emitting diode or other light emitting device. The light source 3 can be used to indicate the working status of the electronic device. For example, the light source 3 is used to indicate whether the electronic device is turned on, or to indicate whether the electronic device is connected to a power adapter, or to indicate the power level of the built-in power supply of the electronic device, etc.
