For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.
[0035] In conjunction with the accompanying drawings, some embodiments of the present application are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.
[0036] refer to Figure 1 This application discloses a light guide component, which can be applied to a charging pile or other devices that need to display on a housing 10. This application does not impose specific restrictions on the applicable products of the light guide component.
[0037] Combination Figure 2 and Figure 3 The light guide assembly includes a shell 10, a lamp board 30 and a bracket 20; the shell 10 has a light-transmitting area 11; the bracket 20 is installed on the inner surface of the light-transmitting area 11, and the lamp board 30 is installed on the bracket 20; wherein the bracket 20 has a light-guiding channel 21 extending from the lamp board 30 to the light-transmitting area 11, and the light-emitting element 31 on the lamp board 30 is immersed in the light-guiding channel 21.
[0038] In this way, by setting the light-transmitting area 11 on the outer shell 10, the lamp board 30 is installed on the inner surface of the light-transmitting area 11 through the bracket 20, and because the bracket 20 has a light-guiding channel 21 extending from the lamp board 30 to the light-transmitting area 11, the light-emitting element 31 on the lamp board 30 is sunk into the light-guiding channel 21, so that the lamp board 30 covers the light-guiding channel 21, and the light-emitting element 31 is wrapped by the bracket 20 and the lamp board 30. When emitting light, the light can only reach the light-transmitting area 11 through the light-guiding channel 21, and will not escape from the gap between the bracket 20 and the lamp board 30, thereby achieving the anti-light-channeling effect, so that the user can observe a clear light display effect from the outside of the outer shell 10. Compared with the prior art, secondary injection molding and encapsulation are no longer required. The lamp board 30 and the bracket 20 can be assembled first and then installed on the outer shell 10 together. The assembly is convenient, quick and the cost is also lower.
[0039] Optional, combined Figure 3 and Figure 4 The shell 10 is formed by integral injection molding of a transparent or translucent material such as a light-transmitting material. A local area of the shell 10 is thinned to form a light-transmitting area 11. The shape of the light-transmitting area 11 is adapted to the shape of the light outlet of the light-guiding channel 21. The thickness of the light-transmitting area 11 is less than the thickness of other areas of the shell 10. The shell 10 formed by integral injection molding has good overall external consistency and is not easily deformed during injection molding, thereby ensuring the overall strength of the shell 10. After the injection molding is completed, the light-transmitting area 11 formed by thinning through processes such as debonding treatment has a smaller thickness, which is more conducive to light transmission and ensures the brightness and effect of the light display.
[0040] In more detail, the area formed after the thinning treatment on the inner surface of the shell 10 is divided into the light-transmitting area 11 and the transition area 14 surrounding the light-transmitting area 11; the thickness of the transition area 14 gradually decreases from the outer edge of the transition area 14 to the light-transmitting area 11; the thickness of the light-transmitting area 11 remains constant from the outer edge of the light-transmitting area 11 to the inside. In this way, the thickness of the shell 10 gradually decreases from the transition area 14 to the thickness of the flat light-transmitting area 11, and the transition is smoother. Even after thinning, the strength of the shell 10 can meet the requirements and is not easy to deform. At the same time, the light-transmitting area 11, which is flat and has a small overall thickness, has a better light-transmitting effect, so as to ensure the brightness displayed from the light-transmitting area 11 when the light-emitting element 31 is working.
[0041] Of course, in some embodiments, the light-transmitting area 11 may also be formed by directly machining the housing 10. In addition, the housing 10 may also be partially machined to form a window, and then a window mirror made of a transparent or translucent material may be installed in the window.
[0042] Combination Figure 2 and Figure 3 The light-guiding channel 21 provided on the bracket 20 is in the shape of a stepped hole, that is, the light-guiding channel 21 has an introduction portion 211 and an indication portion 212 which are connected to each other. The inner diameter of the introduction portion 211 is larger than the inner diameter of the indication portion 212. The indication portion 212 corresponds to the light-transmitting area 11, and the introduction portion 211 corresponds to the light board 30. The light-emitting element 31 is sunk into the introduction portion 211. In this way, when the light-emitting element 31 emits light, the light can enter the indication portion 212 with a smaller inner diameter after diffuse reflection at the introduction portion 211, and then be transmitted to the light-transmitting area 11 to penetrate to the outside, thereby improving the uniformity of light display. Moreover, the change in the inner diameter of the introduction portion 211 and the indication portion 212 can play a role of focusing light to a certain extent, thereby improving the brightness of light display.
[0043] Of course, in some embodiments, the inner diameter of the light guide channel 21 can also be a straight hole that remains constant from the light board 30 to the light-transmitting area 11, or a gradually converging tapered hole. The present application does not impose specific restrictions on this, and it can be adjusted accordingly according to actual needs.
[0044] It can be understood that the shape of the indicating part 212 of the light guiding channel 21 corresponding to the light emitting side of the light transmitting area 11 is the shape of the light display pattern that can be observed from the outside of the housing 10. For example, in the embodiment shown in the accompanying drawings, the bracket 20 has two light guiding channels 21, one light guiding channel 21 is elongated as a whole, and the other light guiding channel 21 is circular as a whole. The corresponding lamp board 30 has light-emitting elements 31 sunk into the light guiding channels 21 at the positions corresponding to the two light guiding channels 21. At the same time, the housing 10 has an elongated light transmitting area 11 and a circular light transmitting area 11. The thickness of the spacing area 15 between the two light transmitting areas 11 can be the same as the thickness of the light transmitting area 11. In this way, when the lamp board 30 is working and the light-emitting element 31 is lit, a circular light display pattern and a elongated light display pattern can be displayed on the surface of the housing 10.
[0045] The bracket 20 and the light board 30 can be assembled by snap-fitting, for example, Figure 3 , Figure 5 and Figure 6 At least two hooks 22 are provided on the side of the bracket 20 facing away from the light-transmitting area 11 , and each hook 22 abuts against a side of the light board 30 facing away from the bracket 20 .
[0046] Among them, each hook 22 can be directly around the outer periphery of the lamp board 30, and of course, at least two penetrating holes 32 can be set on the lamp board 30. Correspondingly, each hook 22 passes through a hole 32 and abuts against the side of the lamp board 30 facing away from the bracket 20. This can reduce the volume of the bracket 20 and save materials. At the same time, the overall length and width dimensions of the bracket 20 and the lamp board 30 are basically the same, which can improve the compactness of the overall structure.
[0047] Of course, it is understandable that the number of the hooks 22 and the holes 32 can also be three, four or more than five, as long as the hooks 22 and the holes 32 can correspond one to one to ensure that the connection between the lamp board 30 and the bracket 20 is reliable.
[0048] In addition, the assembly of the lamp panel 30 and the bracket 20 is not limited to the above-mentioned snap-fit connection, and can also be bolted, connected by axial hole interference fit, or bonded.
[0049] Optionally, in order to ensure the precise position of the light board 30 and the bracket 20 during assembly, thereby ensuring that the light-emitting element 31 on the light board 30 can be accurately sunk into the light guide channel 21, a positioning column 23 can be set on the side of the bracket 20 facing away from the light-transmitting area 11, and a positioning hole 33 can be set on the light board 30 accordingly. The positioning hole 33 can be a through hole that passes through the light board 30 or a blind hole that is only set on the side of the light board 30 facing the bracket 20. The positioning column 23 is inserted into the positioning hole 33. In this way, the assembly position of the light board 30 and the bracket 20 can be determined by the cooperation of the positioning column 23 and the positioning hole 33, and pre-positioning can be achieved, which is conducive to the rapid assembly of the light board 30 and the bracket 20.
[0050] Among them, the positioning column 23 can be cylindrical, and the corresponding positioning hole 33 can be a circular hole. Of course, in some embodiments, the positioning column 23 can also be a polygonal column or a cylinder with at least one flat position, and the corresponding positioning hole 33 can be a polygonal hole or a circular hole with at least one flat position, as long as the positioning column 23 can be inserted into the positioning hole 33 to achieve cooperation.
[0051] In order to realize the assembly of the bracket 20 and the housing 10, refer to Figure 1 , Figure 4 and Figure 5 At least two connecting parts 12 can be formed on the inner surface of the shell 10, and each connecting part 12 is distributed on the outer peripheral side of the light-transmitting area 11. At the same time, a connecting hole 121 is set on the end surface of the connecting part 12, and a fastener 40 such as a screw, rivet or pin passes through the bracket 20 and is locked into the connecting hole 121, so that the assembly connection of the shell 10 and the bracket 20 can be achieved.
[0052] It should be noted that if the overall length and width of the light board 30 and the bracket 20 are substantially the same, for example Figure 1 and Figure 2As shown, the fastener 40 needs to pass through the lamp board 30 and the bracket 20 in sequence before it can be locked into the connecting hole 121. Based on this, refer to Figure 5 and Figure 6 Therefore, at least two first through holes 34 are provided on the lamp board 30, and at least two second through holes 24 are provided on the bracket 20. The first through holes 34, the second through holes 24 and the connecting hole 121 correspond to each other and are connected in sequence, so that each fastener 40 can be connected to a first through hole 34 and a second through hole 24 corresponding to the first through hole 34 in sequence and locked into a corresponding connecting hole 121.
[0053] The second through hole 24 may be a countersunk through hole, so that the connecting portion 12 may be partially embedded in the second through hole 24 for pre-positioning and then locked by the fastener 40 .
[0054] Of course, it is understandable that in some embodiments, if the bracket 20 has an extended portion extending laterally relative to the light board 30, the extended portion is provided with a second through hole 24. At this time, the fastener 40 can directly pass through the second through hole 24 on the extended portion and lock into the connecting hole 121. Therefore, in this case, it is feasible that the light board 30 is not provided with the first opening.
[0055] Optional, reference Figure 1 and Figure 4 At least two limiting parts 13 are formed on the inner surface of the shell 10, and each limiting part 13 is distributed on the outer peripheral side of the light-transmitting area 11. The limiting part 13 has a limiting groove 131. The bracket 20 is located between all the limiting parts 13 and cooperates with the limiting groove 131. In this way, the limiting groove 131 of each limiting part 13 cooperates with the bracket 20 to share and place the bracket 20. In this way, before using the fastener 40 to lock it, the position of the bracket 20 relative to the shell 10 can be determined, and there is sufficient stability to ensure that the position of the bracket 20 relative to the shell 10 will not shift, thereby ensuring the accurate position of the light-display pattern.
[0056] The bracket 20 and the light board 30 are both roughly rectangular, so each limiting portion 13 simultaneously contacts two adjacent side surfaces of the bracket 20 and the surface facing the housing 10 through the inner wall of the limiting groove 131 provided therein.
[0057] Optional, reference Figure 3 , Figure 5 and Figure 6The light guide assembly also includes a light guide member 50. The shape of the light guide member 50 is adapted to the shape of the light guide channel 21. The light guide member 50 is injection molded with a transparent material and can be divided into a first part 51 and a second part 52. The shape of the first part 51 is adapted to the introduction part 211 of the light guide channel 21, and the shape of the second part 52 is adapted to the indication part 212 of the light guide channel 21. The light guide member 50 is accommodated in the light guide channel 21, that is, the first part 51 is accommodated in the introduction part 211, and the second part 52 is accommodated in the indication part 212. In this way, the light incident side of the light guide member 50 corresponds to the light-emitting element 31, and the light emitting side of the light guide member 50 extends to the light-transmitting area 11, so that the light guide member 50 can achieve a uniform light effect, so that the brightness of the pattern displayed on the housing 10 is more uniform when the light panel 30 is working and the light-emitting element 31 is lit.
[0058] When assembling the light board 30, the light guide 50 and the bracket 20, the light guide 50 can be placed into the light guide channel 21 first, and then the light board 30 is covered on the bracket 20 and fixed. In this way, the light guide 50 can be limited by the bracket 20 and the light board 30, thereby achieving the fixation of the light guide 50.
[0059] A groove 511 is provided on the side of the light guide 50 facing the lamp board 30, and the light emitting element 31 is sunk into the groove 511, so that the inner wall surface of the groove 511 constitutes the light incident side of the light guide 50. After the light emitting element 31 is lit, the part of the light that does not directly enter the light guide 50 will repeatedly undergo diffuse reflection between the inner wall of the groove 511 and the lamp board 30 before entering the light guide 50, thereby ensuring as much as possible that all the light can be transmitted from the light guide 50 to the light-transmitting area 11, thereby improving the utilization rate of the light.
[0060] The side of the light guide 50 close to the light board 30 is at least sunken or flush with the side of the light guide channel 21 close to the light board 30, that is, the light guide plate is sunken or flush with the bracket 20 facing away from the light-transmitting area 11, so as to ensure that the light guide 50 will not lift up the light board 30.
[0061] It should also be noted that, since there are two light guide channels 21 in the embodiment shown in the drawings, there are also two light guide members 50 , one light guide member 50 is generally circular, and the other light guide member 50 is generally elongated.
[0062] In addition, an embodiment of the present application also discloses a charging pile, which has the light guide component of the above embodiment, and therefore also has the corresponding structure and beneficial effects, which will not be described in detail here, and reference can be made to the above content.
[0063] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
