Description

Technical Field

[0001] The utility model relates to the field of light guide columns, in particular to an electronic device light guide column and an electronic device structure. Background Art

[0002] A light guide column is an optical component that guides light from one point to another. It is usually made of light-guiding materials such as acrylic and PC. It is often used in electronic devices to guide the directional propagation of light. For example, the light of a light-emitting circuit board is emitted from the light source on the light-emitting circuit board. After being propagated to the designated position through the light guide column, it passes through the outer shell and propagates to the outside of the outer shell. This allows the internal light of the electronic device to be propagated to the outside of the electronic device, allowing the user to observe and obtain the operating information of the electronic device. At the same time, it also makes the brightness and color of the light of the electronic device more uniform and clear, thereby improving the visual experience of the display effect.

[0003] In some electronic devices, the light-emitting circuit board inside the electronic device is not connected to the port of the outer shell by the circuit terminal on the circuit board, but is connected to the wires running through the outer shell to transmit electricity with the external electronic device. However, when the wires are connected to the light-emitting circuit board and routed, the wires need to pass through the light guide column on the circuit board, which can easily block the light source on the light-emitting circuit board. Most of the light propagating from the light source to the specific position of the light guide column is blocked, and the light emitted by the light source cannot be evenly distributed at the specific position, resulting in the inability to ensure that the light passes through the outer shell of the electronic device from the specific position of the light guide column to propagate.

[0008] The wire-threading portion includes two independent wire-threading holes formed by the two light-guiding blocks, the light-collecting portion and the light-guiding column body; the two wire-threading holes both pass through the second end of the light-guiding column body and are interconnected.

[0009] In the above-mentioned light guide column of the electronic device, the light receiving portion, the light receiving hole and the light guide column body are coaxially arranged; and the two light guide blocks are symmetrically arranged.

[0010] In the above-mentioned electronic device light guide column, the light receiving hole is a blind hole structure.

[0011] In the above-mentioned electronic device light guide column, the outer diameter of the refractive particles ranges from 6 to 10 μm.

[0012] In the above-mentioned electronic device light guide column, a first end of the light guide column body is provided with a slot for inserting the light-emitting circuit board.

[0013] In the above-mentioned electronic device light guide column, a convex ring is also provided on the end of the first end of the light guide column body, the light collecting part and the wire threading part are both arranged in the inner circle of the convex ring, the bayonet is arranged on the convex ring, and an annular groove coaxially arranged therewith is provided on the outer peripheral surface of the convex ring so that a fixing part on the light-emitting circuit board can be clamped in the annular groove.

[0029] The technical solution of the present invention is further described in detail below in conjunction with specific implementation methods, but does not constitute any limitation to the present invention.

[0030] Embodiment 1:

[0031] like Figure 1-8 As shown, the electronic device light guide column comprises a light guide column body 1 for being sleeved on the electric wire 3, a plurality of refractive particles are arranged on the light guide column body 1, and the plurality of refractive particles are dispersed along the circumference of the light guide column body 1 and arranged around to form a light-emitting belt 11; a light receiving portion 12 and a light guiding portion arranged on the light receiving portion 12 are arranged in the first end of the light guide column body 1, and a light receiving hole 121 for inserting the light source 21 of the light-emitting circuit board 2 is opened on the light guide portion;

[0032] The light guiding part extends onto the light guide column body 1 and faces the light emitting strip 11; a threading part is enclosed between the light guiding part, the light receiving part 12 and the light guide column body 1, and the threading part passes through the second end of the light guide column body 1, so that the power line 3 passes through the first end and the second end of the light guide column body 1 along the threading part and is connected to the light emitting circuit board 2.

[0033] The working principle is as follows: a light receiving portion 12 is arranged in the light guide column body 1, and the light source 21 on the light-emitting circuit board 2 is inserted into the light receiving hole 121 of the light receiving portion 12, and the wire 3 passes through the first end and the second end of the light guide column body 1 through the threading portion and is connected to the light-emitting circuit board 2. The light emitted by the light source 21 is transmitted to the light guiding portion through the light receiving portion 12, and then transmitted to the light-emitting belt 11 through the light guiding portion. The light-emitting belt 11 serves as a specific position of the light guide column body 1 for allowing light to pass through the housing of the electronic device. The light-emitting belt 11 is formed by a plurality of refractive particles that are dispersed and arranged. When the light is transmitted to the light-emitting belt 11, the light is continuously refracted there, and finally the light is evenly distributed in the light-emitting belt 11. The propagation path of the above-mentioned light is independent of the extension path of the wire 3, thereby avoiding the light of the light-emitting circuit board 2 from being blocked by the wire 3 passing through the light guide column, so that the light is evenly distributed in the specific position of the light guide column, ensuring that the light can pass through the housing of the electronic device for transmission.

[0034] Combination Figure 1 and Figure 5 As shown, the specific structure of the light guide part is that the light guide part includes two light guide blocks 16 spaced apart on the light guide column body 1 , and the two light guide blocks 16 both extend onto the light guide column body 1 and both face the light-emitting strip 11 .

[0035] The specific structure of the threading part is that the threading part includes two independent threading holes 14 formed by two light guide blocks 16, the light receiving part 12 and the light guide column body 1; the two threading holes 14 both pass through the second end of the light guide column body 1 and are connected to each other.

[0036] In the present embodiment, two light guide blocks 16 are arranged to increase the contact points between the light receiving part 12 and the light guide column body 1. One light guide block 16 serves as a branch path for light propagation, so that the light receiving part 12 can propagate light through multiple branch paths. The increase in contact points allows the light to be directly propagated to different positions of the light-emitting strip 11, and does not require the light to be continuously refracted and propagated on the light-emitting strip 11 to be propagated to different positions, thereby reducing the decrease in light energy and improving the propagation efficiency and effect.

[0037] In some embodiments, either one or more than three light guide blocks 16 may be provided. When one light guide block 16 is provided, a wire hole 14 is enclosed between the light guide block 16, the light receiving portion 12 and the light guide column body 1. At this time, the wire hole 14 is the threading portion. When three light guide blocks 16 are provided, three light guide blocks 16, the light receiving portion 12 and the light guide column body 1 are enclosed together to form three wire holes 14. At this time, the three wire holes 14 are the threading portion. The number of light guide blocks 16 matches the number of wire holes 14. This embodiment does not impose excessive restrictions on the number of light guide blocks 16 and the wire holes 14.

[0038] Among them, the more wire holes 14 there are, the more the wires 3 can pass through different wire holes 14, and the different wire cores 31 on the wires 3 can pass through different wire holes 14 respectively, so that the actual installation can be flexibly selected according to the actual situation, thereby improving the practicality of the product.

[0039] Combination Figure 1 and Figure 5 As shown, preferably, the light receiving portion 12 , the light receiving hole 121 and the light guide column body 1 are coaxially arranged; and the two light guide blocks 16 are symmetrically arranged.

[0040] The light receiving part 12, the light receiving hole 121 and the light guide column body 1 are coaxially arranged, so that the light receiving part 12 and the light receiving hole 121 are all on the axis of the light guide column body 1, and the light receiving hole 121 is at the same distance from each point on the outer surface of the light guide column. At the same time, through the cooperation of two symmetrical light guiding blocks 16, the light in the light receiving hole 121 is evenly propagated to the opposite sides of the light guide column body 1, and the light is diffused and propagated from the local parts of the light-emitting strip 11 on the opposite sides of the light guide column body 1 along the light-emitting strip 11, and the light on both sides spreads to each other until the light on both sides merges with each other, and the light-emitting strip 11 is uniformly illuminated as a whole.

[0041] Combination Figure 4 and Figure 8 As shown, in another preferred embodiment, the light receiving hole 121 is a blind hole structure.

[0042] The light receiving hole 121 adopts a blind hole structure, so that part of the light emitted by the light source 21 is transmitted to the light guiding part through the light receiving part 12, and part of the light that has not been transmitted by the light receiving part 12 is continuously reflected and refracted in the light receiving hole 121 to avoid scattering everywhere, so that the light is relatively concentrated in the light receiving part 12, thereby improving the light transmission quality.

[0043] In practical applications, the outer diameter of the refractive particles ranges from 6 to 10 μm.

[0044] The outer diameter of the refractive particles is preferably 8 μm. If the outer diameter of the refractive particles is less than 6 μm, the luminous strip 11 cannot refract a large amount of light because the refractive particles are too small, resulting in a weakened refraction effect and the light cannot be evenly distributed on the luminous strip 11. If the outer diameter of the refractive particles is greater than 10 μm, the luminous strip 11 blocks or reflects light because the refractive particles are too large, resulting in a weakened refraction effect and also making it impossible for the light to be evenly distributed on the luminous strip 11.

[0045] Combination Figure 1-Figure 8 As shown, in a further improvement, a first end of the light guide body 1 is provided with a slot 131 for inserting the light emitting circuit board 2 .

[0046] The setting of the bayonet 131 allows the light source 21 on the circuit board to be accurately inserted into the light receiving hole 121 when the circuit board is clamped on the bayonet 131, providing installation positioning; after the installation is completed, the circuit board is clamped by the bayonet 131 to avoid relative rotation and other rotational displacement between the light guide column body 1 and the circuit board.

[0047] Another improvement of the present embodiment is that a convex ring 15 is further provided on the end of the first end of the light guide column body 1, the light receiving portion 12 and the threading portion are both arranged in the inner circle of the convex ring 15, the bayonet 131 is arranged on the convex ring 15, and an annular groove 151 coaxially arranged therewith is provided on the outer peripheral surface of the convex ring 15 so that the fixing part on the light-emitting circuit board 2 can be clamped in the annular groove 151.

[0048] Whenever the light-emitting circuit is connected to the light-guiding column body 1 by using heat-deformable fixing parts such as hot-melt adhesive blocks, potting adhesive blocks and injected plastic blocks (i.e., fixing parts on the light-emitting circuit board 2), before the heat-deformable fixing parts are cured, they are allowed to extend into the annular groove 151, so that the fixed heat-deformable fixing parts can be fixedly connected to the light-emitting circuit board 2 and the convex ring 15 and its annular groove 151 respectively. The annular groove 151 serves as a clamping structure on the light-guiding column body 1, making the connection between the heat-deformable fixing parts and the light-guiding column body 1 more secure.

[0049] Preferably, a protrusion 13 is provided on a side of the convex ring 15 facing away from the light guide column body 1 , and the bayonet 131 is provided on the protrusion 13 .

[0050] The protrusion 13 is provided to avoid directly hollowing out the light guide column body 1, thereby avoiding reducing the strength of the light guide column body 1 itself, and also avoiding interfering with the propagation path of the light.

[0051] In another preferred embodiment, two protrusions 13 and two bayonet holes 131 are provided, and the bayonet holes 131 correspond to the protrusions 13 one by one.

[0052] The provision of the two bayonet holes 131 increases the connection points with the light-emitting circuit board 2 , thereby improving the positioning accuracy and the clamping strength of the light-emitting circuit board 2 .

[0053] Combination Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, the electronic device structure includes a wire 3 and the electronic device light guide column as described above, the wire 3 is inserted into the threading part, a filler is filled between the wire 3 and the threading part, and the wire 3 is fixedly connected to the light guide column body 1 through the filler.

[0054] In actual applications, the inner diameter of the threading part is larger than the outer diameter of the wire 3, so that the wire 3 can pass through easily. During installation, heat-deformable materials such as hot melt adhesive, potting adhesive and injection plastic are used as fillers. Before the filler is fixed, it enters the interior through the port of the threading part for filling. After the filler is fixed, the wire 3 is fixed in the wire hole 14. The filler plays a role of sealing, waterproofing and fixed support.

[0055] In some embodiments, in addition to passing the entire wire 3 through the threading portion, the entire wire 3 can also be inserted into the threading portion, and the wire cores 31 of the wire 3 are separately passed out from the threading portion. This embodiment does not impose too many restrictions on the threading form of the wire 3.

[0056] The above embodiments are preferred implementation modes of the present invention, but the implementation modes of the present invention are not limited by the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principle of the present invention should be equivalent replacement methods and are included in the protection scope of the present invention.
