Description

Technical Field

[0001] The present application relates to the technical field of communication equipment, and in particular to a light guide column structure and terminal equipment. Background Art

[0002] Currently, terminal products (such as gateways, integrated terminals, etc.) usually have the need for multiple LED lights to guide light, and generally require the design of multiple light positions to display the status.

[0003] In some related technologies, the connection of multiple light guides is generally fixed by hot melting in batches, but this method increases the cost of hot melting. In addition, LED lamps are usually arranged on the A-level surface (front) of the shell, and the internal structure is compact. When an optical fiber or antenna passes through the front, due to space limitations, the optical fiber or antenna is fixed to the PCB with adhesive backing, which also leads to an increase in the cost of hot melting.

[0004] In other related technologies, due to space limitations, the distance between each lamp position is very small. When one lamp position is on, the light source will be transmitted to another lamp position, resulting in cross-light. To solve the problem of cross-light between adjacent lamp positions, foam needs to be pasted on the PCB, which increases the cost of foam materials and manual assembly. Utility Model Content

[0033] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0034] Currently, terminal products usually have the need for multiple LED lights to guide light, and generally require the design of multiple light positions to display status.

[0035] The problems are:

[0036] (1) The connection of multiple light guides is generally fixed by hot melting in batches, but this method increases the cost of hot melting. In addition, LED lights are usually arranged on the A-level surface (front) of the shell, and the internal structure is compact. When an optical fiber or antenna passes through the front, the optical fiber or antenna is fixed on the PCB by adhesive due to space limitations, which also leads to an increase in hot melting costs.

[0037] (2) Due to space limitations, the distance between each lamp position is very small. When one lamp position is on, the light source will be transmitted to another lamp position, resulting in cross-light. To solve the problem of cross-light between adjacent lamp positions, foam needs to be attached to the PCB, which increases the cost of foam materials and manual assembly.

[0038] Therefore, a multifunctional LED light guide column was developed, which can solve the problem of stringing light from multiple adjacent LED lights, the problem of installing the light guide column, and the problem of routing the optical fiber or antenna on the front of the shell.

[0039] In order to gradually explain the solution of this application, the following will start from individual problems and explain them one by one.

[0040] First, in a first aspect, an embodiment of the present application provides a light guide column structure to solve the problem in the related art that the connection of multiple light guide columns is fixed by hot-melt multiple times, which increases the hot-melt cost and installation steps.

[0041] See also Figure 1 and Figure 2 , a light guide column structure, comprising:

[0042] Multiple light guide column bodies 1 are spaced apart along the design track, and two adjacent light guide column bodies 1 are connected by light guide column connectors 2; the light guide column bodies 1 at both ends of the design track are connected with housing connectors 3. The design track refers to the arrangement of multiple light guide column bodies 1, which can be distributed in a straight line or a curve. The design track can be referred to in the attached Figure 2 The mark H, the design trajectory includes but is not limited to straight lines, curves and arcs.

[0043] The light guide column body 1 includes a horizontal portion, one end of which is connected to a vertical portion in the vertical direction, and the other end of the horizontal portion is provided with a light inlet portion; and the end of the vertical portion away from the horizontal portion is provided with a light outlet portion;

[0044] The light guide column connector 2 includes a U-shaped connector 200, which is located above the horizontal portion, and its two ends extend downward to be fixedly connected to the horizontal portions of the corresponding two light guide column bodies 1. Of course, the light guide column connector 2 can also be a horizontal plate or a V-shaped plate, etc., as long as it plays a connecting role.

[0045] The light guide column connector 2 also includes a wire buckle 201. A slot is provided on the top of the U-shaped connector 200. At least one slot is inserted into a wire buckle 201. In the following text, this slot is also connected to the limiter 6. The number of wire buckles 201 can be designed according to needs, and can refer to Figure 1 and Figure 2 and Figure 3 shown.

[0046] In the above, multiple light guide column bodies 1 are formed into an integral structure, and do not need to be fixed in batches, so that when installing multiple light guide column bodies 1, they can be installed as a whole at one time, and the shell clamping member 3 can be connected to the corresponding clamping column 5 in the shell 4 of the terminal device, thereby avoiding the problem of cumbersome installation steps and increased costs caused by the glue hot-melt fixation of multiple light guide column bodies 1 in batches. A wire buckle 201 can also be set on the light guide column connector 2 to simplify the mold and beautify the routing path for antenna and optical fiber routing.

[0047] Furthermore, the specific structure of the housing clamping member 3 is:

[0048] The housing clamping member 3 includes an L-shaped connector 300, the bottom of the vertical plate of the L-shaped connector 300 is connected to the horizontal part of the corresponding light guide column body 1, and a clamping groove 301 is provided on the horizontal plate of the L-shaped connector 300; the height of the horizontal plate is equal to the height of the top of the U-shaped connector 200. When connected, the horizontal plate of the L-shaped connector 300 overlaps the enclosure structure 8 in the housing 4, and then the column 5 is clamped to the clamping groove 301.

[0049] Furthermore, a PCB support column 100 is provided on the horizontal portion, and the height of the top of the PCB support column 100 is less than the height of the top of the U-shaped connector 200. The PCB support column 100 is designed on the light guide column body 1, and the PCB support column 100 contacts the welding surface of the PCB to prevent the LED lamp from being damaged when the product falls.

[0050] The above introduces the specific structure of the light guide column structure, but the structure alone cannot achieve the function of preventing crosstalk, so it needs to be used in conjunction with the shell of the terminal device, so a terminal device is also proposed.

[0051] A terminal device, comprising:

[0052] The light guide column structure described above;

[0053] Shell 4;

[0054] The enclosure structure 8 is located inside the shell 4 and encloses an installation space together with the inner wall of the shell 4 . The enclosure structure 8 is provided with a clamping column 5 that matches and clamps with the shell clamping piece 3 .

[0055] The above problem is that only the two ends of the light guide column structure are limited, but there is no limit for the middle position. After being hit or bumped, there is a situation of overall dislocation, so multiple limiters 6 are set in the installation space; multiple limiters 6 divide the installation space into multiple subspaces 10; each subspace 10 corresponds to a light guide column body 1, and each limiter 6 corresponds to a light guide column connector 2; the top of the limiter 6 has a limit card slot 7 engaged with the light guide column connector 2 to support and limit the light guide column connector 2. The side wall of the limit card slot 7 is limited and engaged, and the bottom wall is supported.

[0056] In some preferred embodiments, in order to reduce crosstalk and utilize the structural characteristics of the U-shaped connector 200, the following settings are provided:

[0057] The housing 4 is provided with a display hole 400 connected to the light emitting part and a guide vertical rib 600; a PCB board 13 is provided in the housing 4, a part of the PCB board 13 covers the installation space, and the part is located above the horizontal part and the light inlet part, and a plurality of LDE lamps 9 corresponding to the light inlet part are provided on the bottom surface of the part, and the part contacts the top of the PCB board support column 100;

[0058] The limiting member 6 includes a partition shading plate, and a U-shaped connector 200 is correspondingly engaged with the top of the partition shading plate through a limiting card slot 7, and the two ends of the U-shaped connector 200 extend into a subspace 10 and are connected to the horizontal part. The guide vertical rib 600 is located and connected to one side of the partition shading plate to limit the movement of the U-shaped connector 200 in the direction of the designed trajectory; the above is achieved by limiting the height direction and the front-to-back direction of the shell 4 through the limiting card slot 7 and the U-shaped connector 200, and limiting the left and right direction of the shell 4 through the guide vertical rib 600, so as to ensure the overall stability of the light guide column structure; wherein the role of the reference guide vertical rib 600 Figure 3 and Figure 4 As shown, the left and right directions are the designed trajectory directions.

[0059] like Figure 5 As shown, the slot is marked X; the top of the U-shaped connector 200 has a boss, and the slot on the boss can be connected to a plug-in block, and the top of the plug-in block is provided with two inverted L-shaped elastic buckles; the two inverted L-shaped elastic buckles constitute a wire buckle 201, and the gap between the two buckles can be controlled by the deformation of the buckles. When the antenna or optical fiber passes through the front area of ​​the bottom shell, it can be clamped in a fixed area by the wire buckle, which increases the convenience of wiring. This wire buckle can form a whole with the light guide column, or a round or square hole can be designed on the light guide column for use with an independent wire buckle.

[0060] The above structural forms can refer to the schematic diagram Figure 4 and Figure 5 The partition shading plate is an equal-height shading plate, which can effectively shade part of the horizontal part and weaken it, thus solving the problem of cross-lighting to a certain extent.

[0061] Furthermore, in order to improve the shading effect, a PCB mounting groove 11 is provided in the area above the PCB support column 100 and close to the top of the partition shading plate, on one side of the PCB 13; the depth of the PCB mounting groove 11 is greater than the depth of the limit slot 7. In this form, the installation height of the PCB 13 can be lowered, so that it is closer to the light inlet, with a smaller light irradiation divergence range, and the side wall of the enclosure structure 8, the bottom surface of the PCB 13, the partition shading plate, and the housing 4 are combined to form a closed area, so that each LDE lamp 9 can be shielded in five directions, so that more light can be irradiated to the light inlet, which better solves the problem of light crosstalk than the previous structure.

[0062] Furthermore, to improve the shading effect, a vertically extended shading plate 12 connected to the inner wall of the housing 4 is provided at the top of the shading plate and in the area between the U-shaped connector 200 and the display hole 400, and the top of the vertically extended shading plate 12 is at a height greater than the height of the light-emitting portion. Such a design is that the height of the light-emitting portion is different from that of the horizontal portion, and in order to prevent the light-traffic effect between the light-emitting portion and the vertical portion, the vertically extended shading plate 12 is set as high as possible in the vertical direction.

[0063] Therefore, the best embodiment forms three light-shielding areas, such as Figure 5 As shown, the shading area a, the shading area b, and the shading area c, the heights of different shading areas also correspond to different parts of the light guide column body 1; the three shading areas isolate and shield the horizontal parts and the horizontal parts, the vertical parts and the vertical parts, the light input parts and the light output parts of two adjacent light guide column bodies 1; so that the LED lamp 9 is illuminated, and the light is output through the light input surface, the reflection surface, the light guiding path of the light guide column, the light output surface and other structures of the light guide column, thereby solving the problem of cross-lighting to the greatest extent.

[0064] In summary, the above light guide column structure, in conjunction with the corresponding shading structure in the housing, can solve the problem of multiple adjacent LED lights stringing together, the problem of light guide column installation, and the problem of optical fiber or antenna routing on the front of the housing. The above terminal devices include but are not limited to wireless routers, smart gateways, and integrated terminals.
