Abstract
Description
Technical Field
[0001] This application relates to the field of bicycle lights, specifically to an optical module. Background Technology
[0002] In the current technological field, bicycle taillights, as an important piece of equipment for cycling safety, have always been a focus of research and development in terms of functionality and design. Bicycle taillights on the market are mainly divided into two categories: one with turn signal functionality and the other without. The turn signal function plays a crucial safety role when bicycles change lanes, effectively alerting vehicles and pedestrians behind, thereby reducing the risk of traffic accidents.
[0003] Lenses play a crucial role in bicycle taillights, focusing or diffusing the light emitted from the internal light source to optimize light propagation. Currently, most bicycle taillights with turn signals use elongated, strip-shaped lenses, which are functionally limited and less compact in installation and use, negatively impacting the overall aesthetics and portability of the bicycle. Therefore, improvements and optimizations are still needed for existing bicycle taillight lenses. Utility Model Content

[0043] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other alternative implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0044] This application provides an optical module 100, which can be assembled into, for example, Figure 8 The optical module 100 is used in the bicycle taillight 10 shown. The optical module 100 is small in size and compact in structure. When used in conjunction with the LEDs inside the bicycle taillight 10, it can realize functions such as braking, steering, dynamic display, and interactive team display of the bicycle taillight 10, enriching the display modes of the bicycle taillight 10 and improving the user experience.
[0045] like Figures 1A to 1H As shown, in one embodiment of the optical module 100, the optical module 100 has a comb-like structure, including a transverse light guide 110 and a plurality of longitudinal light guides 130. The transverse light guide 110 has at least one light source input section 120 at its tail end, and a transverse light emission region 111 at its head end. The plurality of longitudinal light guides 130 are spaced apart along the transverse direction of the transverse light guide 110 on one side of the transverse light guide 110. Specifically, in Figures 1A to 1H In the process, multiple longitudinal light guides 130 are distributed on one side of the bottom surface of the transverse light guide 110; and preferably, the multiple longitudinal light guides 130 are all perpendicular to the transverse light guide 110; each longitudinal light guide 130 also has at least one light source input part 120 at its tail, and each longitudinal light guide 130 also has a longitudinal light output area 131, which is located at least at the head of the longitudinal light guide 130.
[0046] In this embodiment, the light source input unit 120 is the mounting position of the light source emitter, used to guide light into the horizontal light guide 110 or the vertical light guide 130; for example, in the bicycle taillight 10, the light source emitter is a lamp bead (e.g., an LED lamp bead) in the bicycle taillight 10, which can emit light after being powered on; the horizontal light guide 110 and the vertical light guide 130 are optical elements that can allow light to propagate; after the light emitted by the lamp bead at the tail of the horizontal light guide 110, the light is refracted inside the horizontal light guide 110 and then emitted from the horizontal light emission area 111; after the light emitted by the lamp bead at the tail of the vertical light guide 130, the light is refracted inside the vertical light guide 130 and then emitted from the vertical light emission area 131; by controlling the lamp bead at the tail of the horizontal light guide 110 and the vertical light guide 130 to emit light or not emit light, a variety of different patterns, dynamic or static display effects can be formed in the horizontal light emission area 111 and multiple vertical light emission areas 131, thereby displaying a variety of driving states through the bicycle taillight 10.
[0047] In this application, the number of longitudinal light guides 130 is 3 to 8. For example, in Figures 1A to 1H as well as Figures 2 to 4 , Figures 7B to 7F In the embodiments shown, the number of longitudinal light guides 130 is four; Figure 5A and Figure 5B and Figure 7A In the embodiments shown, the number of longitudinal light guides 130 is three; Figure 6A and Figure 6B In the embodiments shown, there are 5 longitudinal light guides 130.
[0048] like Figures 1E to 1H As shown, in this embodiment, there are four vertical light guides 130, and correspondingly, each vertical light guide 130 has four vertical light emitting regions 131, which are respectively defined as the first vertical light emitting region 1301, the second vertical light emitting region 1302, the third vertical light emitting region 1303, and the fourth vertical light emitting region 1304. This application uses this embodiment as an example to illustrate that the horizontal light emitting region 111 and the multiple vertical light emitting regions 131 can form various different patterns, dynamic or static display effects.
[0049] The optical module 100 in this embodiment can display the "braking status". Figure 1EIn the diagram, the horizontal light-emitting area 111, the second vertical light-emitting area 1302, and the third vertical light-emitting area 1303 emit light, and the black pattern is used to indicate that they are in the display state. After the horizontal light-emitting area 111, the second vertical light-emitting area 1302, and the third vertical light-emitting area 1303 emit light, they form a "π" shaped pattern, which represents the "braking state". In actual use, the LED is an RGB light source that can emit light of multiple colors. It is preferred that the "π" shaped pattern is displayed with red light.
[0050] In some other embodiments, for example Figure 5A and Figure 5B In the illustrated embodiment, when there are three longitudinal light guides 130, that is, three longitudinal light-emitting regions 131, they are respectively defined as the first longitudinal light-emitting region, the second longitudinal light-emitting region, and the third longitudinal light-emitting region. After the lateral light-emitting region and the second longitudinal light-emitting region emit light, they present a "T"-shaped pattern, which represents the "braking state". In some other embodiments, when there are more than four longitudinal light guides 130, a "π"-shaped pattern or other custom patterns can also be used to represent the "braking state".
[0051] Furthermore, the optical module 100 in this embodiment can display a "double flash status". Figure 1F In the first longitudinal light-emitting region 1301 and the fourth longitudinal light-emitting region 1304 emit light and flash, indicating a "double-flash state". Preferably, in the "double-flash state", the light emitted by the LED is yellow. In some other embodiments, when the number of longitudinal light guides 130 is 3 or more, it is preferable that the "double-flash state" is indicated by the light emitting and flashing of the two longitudinal light-emitting regions 131 on both sides of the edge of the transverse light guide 110.
[0052] Furthermore, the optical module 100 in this embodiment can display "left turn status" and "right turn status". Figure 1G In the middle, the first longitudinal light-emitting region 1301 to the fourth longitudinal light-emitting region 1304 emit light sequentially to indicate the "right-turning state"; similarly, in Figure 1H In this configuration, light is emitted sequentially from the fourth longitudinal light-emitting area 1304 to the first longitudinal light-emitting area 1301, thereby indicating a "left turn state." This method enables auxiliary steering, providing guidance for bicycle turning. In other embodiments, when the number of longitudinal light guides 130 is three or more, the "left turn state" or "right turn state" can also be indicated by referring to the above display method, which will not be elaborated here.
[0053] Furthermore, the optical module 100 in this embodiment can display a "dynamic display effect." The horizontal light-emitting area 111 and the multiple vertical light-emitting areas 131, in conjunction with the various colors of light emitted by the LEDs, can achieve a dynamic display effect. For example, the horizontal light-emitting area 111 and the multiple vertical light-emitting areas 131 can flash, flow, or gradually change at a fixed frequency; the multiple vertical light-emitting areas 131 can flash alternately; the light from the multiple vertical light-emitting areas 131 can flow from left to right or from right to left, simulating dynamic effects, etc.
[0054] Furthermore, when the optical module 100 is integrated into the bicycle taillight 10, it can also enable team formation. For example, if each cyclist in a cycling team has a bicycle taillight 10, and one of the taillights 10 displays a random dynamic color combination via the optical module 100, the other taillights 10 receive a team formation invitation (the taillights 10 can communicate wirelessly via Bluetooth) and respond, displaying the same dynamic color combination. This ensures that each taillight 10 in the cycling team has the same lighting effect, indicating that they belong to the same team. Additionally, during the ride, the identical lighting effect can also help identify members of the same team.
[0055] Furthermore, such as Figures 1A to 1D As shown, the transverse light guide 110 has a transversely arranged plate-like structure with a flat bottom surface and an arched top surface. The surface of the head of the transverse light guide 110 is used as the transverse light emission area 111. In this embodiment, the surface of the head of the transverse light guide 110 is an arc surface. In the transverse direction of the transverse light guide 110, the surface of the head of the transverse light guide 110 is high in the middle and low at both ends.
[0056] In some embodiments, the surface of the head of the transverse light guide 110 may also be planar. In other embodiments, the top surface of the transverse light guide 110 may also be planar; in some embodiments, in order to expand the display area of the transverse light emission region 111, the surface of the head of the transverse light guide 110 includes multiple sub-surfaces, for example... Figure 3A and Figure 3B In the illustrated embodiment, the surface of the head of the transverse light guide 110 includes a first sub-surface 1101, a second sub-surface 1102, a third sub-surface 1103, and a fourth sub-surface 1104. The first sub-surface 1101 and the second sub-surface 1102 are located in the middle region of the head of the transverse light guide 110, and the first sub-surface 1101 is located in front of the second sub-surface 1102. The third sub-surface 1103 and the fourth sub-surface 1104 are located on both sides of the head of the transverse light guide 110.
[0057] Furthermore, such as Figure 1CAs shown, in some embodiments, in order to enhance the display effect of the horizontal light-emitting area 111, a plurality of light-emitting protrusions 150 with arc surfaces are distributed in the horizontal light-emitting area 111, thereby increasing the light-emitting area of the horizontal light-emitting area 111 and improving the display effect; at the same time, these light-emitting protrusions 150 also serve as an appearance decoration effect.
[0058] Furthermore, the longitudinal light guides 130 have a vertically arranged plate-like structure, and there are gaps between the multiple longitudinal light guides 130. For example... Figure 1A and Figure 1D As shown, the circumferential contour of the longitudinal light guide 130 has a longitudinal arc-shaped edge 132 in the form of a line. The longitudinal arc-shaped edge 132 is a curved blade shape, and the longitudinal arc-shaped edge 132 serves as the longitudinal light-emitting area 131. The starting end of the longitudinal arc-shaped edge 132 is located at the head of the longitudinal light guide 130 and is adjacent to the transverse light guide 110. The ending end of the longitudinal arc-shaped edge 132 extends towards the tail of the longitudinal light guide 130 and gradually moves away from the transverse light guide 110.
[0059] like Figure 7A As shown, in some embodiments, the longitudinal light guide 130 is a plate-like structure with a rectangular cross-section, and the surface of the head of the longitudinal light guide 130 is a plane, which serves as the longitudinal light output area 131.
[0060] Furthermore, such as Figure 3A and Figure 3B As shown, in some embodiments, in the two longitudinal light guides 130 distributed on both sides of the edge of the transverse light guide 110, the outer sides of the longitudinal arc-shaped edges 132 of the two longitudinal light guides 130 are partially chamfered, so that the longitudinal light-emitting area 131 is divided into a first longitudinal sub-light-emitting area 1311 and a second longitudinal sub-light-emitting area 1312; the second longitudinal sub-light-emitting area 1312 is inclined relative to the first longitudinal sub-light-emitting area 1311, thereby enhancing the light-emitting area of the longitudinal light guide 130 and enabling it to be displayed laterally.
[0061] In some other alternative embodiments, the above Figure 3A and Figure 3B The outer side of the longitudinal arc-shaped edge 132 of the two longitudinal light guides 130 can be replaced by "doing chamfer treatment" with "doing rounded corner treatment".
[0062] like Figure 4 As shown, in some other embodiments, the longitudinal arc edges 132 of the two longitudinal light guides 130 distributed on both sides of the edge of the transverse light guide 110 are all rounded, thereby enhancing the light-emitting area of the longitudinal light guide 130 and enabling it to be displayed from the side.
[0063] Furthermore, in Figure 4 In order to enhance the display effect of the vertical light-emitting area 131, at least one of the vertical light-emitting areas 131 has multiple light-emitting protrusions 150 with curved surfaces distributed within it; thereby increasing the light-emitting area of the vertical light-emitting area 131 and improving the display effect; at the same time, these light-emitting protrusions 150 also serve as an aesthetic decoration.
[0064] Furthermore, such as Figures 1A to 1H As shown, in some embodiments, each longitudinal light-emitting region 131 has light-emitting protrusions 150 with arc-shaped surfaces distributed within it; Figures 3A to 4 In the illustrated embodiment, only the two middle longitudinal light-emitting regions 131 have light-emitting protrusions 150 with curved surfaces. In other embodiments, whether each longitudinal light-emitting region 131 has light-emitting protrusions 150 can be adjusted according to display needs; various distribution methods will not be listed here.
[0065] Furthermore, such as Figures 7B to 7D As shown, in some embodiments, the optical module 100 further includes a head extension 191 and a lateral extension 192. The head extension 191 is disposed at the head of the transverse light guide 110 and extends in a direction away from the longitudinal light guide 130. Preferably, the head extension 191 is integrated with the head of the transverse light guide 110.
[0066] The lateral extension portion 192 has two parts, which are respectively disposed on the outer side of the two longitudinal light guides 130 distributed on both sides of the edge of the transverse light guide 110, that is, the lateral extension portion 192 extends towards the outer side of the longitudinal light guide 130; preferably, the lateral extension portion 192 is integrated with the two longitudinal light guides 130 on both sides of the edge of the transverse light guide 110.
[0067] In this embodiment, the optical module 100 is provided with a head extension portion 191 and a lateral extension portion 192, making the edge contour of the head of the optical module 100 larger than that of other embodiments. This is to enable the optical module 100 to be organically integrated with the housing of the bicycle taillight 10, achieving a smooth transition between the optical module 100 and the housing, and improving the aesthetics of the bicycle taillight 10.
[0068] like Figures 7E to 7FAs shown, in some embodiments, the optical module 100 also has multiple light guide fins 170. Some of the light guide fins 170 are disposed on the side of the transverse light guide 110 away from the longitudinal light guide 130 and adjacent to the head of the transverse light guide 110; some of the light guide fins 170 are disposed on the outer sides of the two longitudinal light guides 130 distributed on both sides of the edge of the transverse light guide 110. The light guide fins 170 have a sheet-like structure, which can enhance the light-emitting area, allowing light to be emitted from the light guide fins 170 after passing through them; on the other hand, the light guide fins 170 can also serve a decorative purpose.
[0069] Furthermore, such as Figure 1B As shown, in this embodiment, the light source input section 120 has a cylindrical structure, and its cross-sectional dimensions gradually decrease in the direction away from the tail end of the longitudinal light guide 130; and as... Figure 1D As shown, when viewed from the side, the light source input section 120 is arched; the light source input section 120 also has a lamp housing cavity 121, which is disposed at the center of the light source input section 120 along the length direction of the light source input section 120, and the lamp housing cavity 121 is used to accommodate the lamp beads.
[0070] Furthermore, the rear end of the transverse light guide 110 is provided with at least two light source input sections 120; for example... Figures 1A to 6B The embodiment shown; in other embodiments, as the width of the transverse light guide 110 increases, more light source input sections 120 can be provided, such as 3, 4, etc.
[0071] Furthermore, the tail portions of the two longitudinal light guides 130 distributed on both sides of the edge of the transverse light guide 110 are respectively provided with two light source input sections 120, thereby enhancing the display effect of the longitudinal light-emitting area 131; the tail portions of the two longitudinal light guides 130 distributed in the middle of the edge of the transverse light guide 110 are respectively provided with one light source input section 120; in some other embodiments, the tail portion of each longitudinal light guide 130 may be provided with two light source input sections 120, and as the vertical height of the longitudinal light guide 130 increases, more light source input sections 120 may be provided, such as 3, 4, etc.
[0072] like Figure 1B As shown, the tail of the transverse light guide 110 is also provided with a positioning part 140, which is preferably provided on both sides of the tail of the transverse light guide 110; and at least a portion of the tails of the longitudinal light guides 130 are provided with positioning parts 140, for example, the tails of the two longitudinal light guides 130 located at the middle of the edge of the transverse light guide 110 are each provided with a positioning part 140; the positioning part 140 has a columnar structure, which facilitates the positioning and installation of the optical module 100 when it is assembled on the bicycle taillight 10; such as Figures 7B to 7FAs shown, in some other embodiments, the optical module 100 has a mounting slot 180 at its tail end, through which the optical module 100 is mounted to the bicycle taillight 10.
[0073] Furthermore, in this embodiment, multiple longitudinal light guides 130 and transverse light guides 110 are integrally formed, which facilitates processing and manufacturing.
[0074] Furthermore, in this embodiment, the optical module 100 is made of PC (polycarbonate) or PMMA (polymethyl methacrylate, acrylic), optical glass, etc.
[0075] Furthermore, such as Figure 8 As shown, this application also provides a bicycle taillight 10 having the aforementioned optical module 100.
[0076] Finally, it should be noted that if any directional indication (such as up, down, left, right, front, back, etc.) is involved in the embodiments of this application, the directional indication is only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.
