Abstract
Description
Technical Field
[0001] This application relates to the field of automotive lighting technology, and more specifically, to a dimming indicator. Background Technology
[0002] According to automotive lighting design specifications, the high beam and low beam modules within a vehicle headlight should be adjustable to change the direction of light output after installation to meet regulatory requirements. Existing vehicle headlights all require a function for manually adjusting the direction of the light output. This adjustment is achieved by inserting a dimming tool between the headlight frame and the vehicle trim, and rotating the tool to be adjusted to change the direction of the light output.
[0003] However, when adjusting headlights, it is difficult to achieve accurate dimming if there is no indication of how much dimming is needed. To overcome this deficiency, existing technology installs a level inside the headlight and uses the level to read the position of the light adjustment to obtain the dimming angle. However, when using a level, it is difficult to make accurate indications due to the vehicle's own posture during dimming, which can easily affect the accuracy of dimming. Summary of the Invention
[0004] The purpose of this application is to address the shortcomings of the prior art by providing a dimming indicator to improve the problem that the level gauge in the prior art is limited by the vehicle's own posture, making it difficult to achieve accurate indication and precise dimming.
[0005] To achieve the above objectives, the technical solutions adopted in the embodiments of this application are as follows:
[0006] In one aspect of this application, a dimming indicator is provided, including a housing and a dimming element and an indicator disposed on the housing. The dimming element is used to cooperate with the dimming axis of a vehicle lamp to drive the element to be dimmed to move around the dimming axis to adjust the light output direction of the vehicle lamp.

[0019] The beneficial effects of this application include:
[0020] This application provides a dimming indicator with a dimming element movably mounted on a housing. The dimming element cooperates with the dimming shaft of a vehicle headlight to drive the element to be dimmed around the dimming shaft.

Detailed Implementation
[0038] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, 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. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.
[0039] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. It should be noted that, unless otherwise specified, the various features in the embodiments of this application can be combined with each other, and the combined embodiments are still within the protection scope of this application.
[0040] In the description of this application, it should be noted that the terms "middle," "upper," "lower," "left," "right," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product is in use, and therefore should not be construed as a limitation of this application. Furthermore, the terms "first," "second," "third," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0041] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "set up" and "connected" should be interpreted broadly. For example, they can refer to a direct connection, an indirect connection through an intermediate medium, or a connection within two elements. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0042] One aspect of this application provides a dimming indicator, such as... Figure 1 As shown, a dimming element 130 is movably disposed on the housing 100. The dimming element 130 is used to cooperate with the dimming shaft of the vehicle lamp to drive the element to be dimmed to move around the dimming shaft. This is so that when an external force is applied to the dimming element 130, the element to be dimmed can be driven to move synchronously around the dimming shaft by the dimming element 130, thereby adjusting the light output direction of the vehicle lamp. This provides the best light according to the development of vehicle design and the actual use, and prevents the light from shining directly on oncoming vehicles and dazzling the drivers of other vehicles.
[0043] Please continue to refer to Figure 1 An indicator 140 is also provided on the housing 100. Since the element to be dimmed moves synchronously around the dimming axis under the drive of the dimming element 130, the movement of the dimming element 130 can accurately represent the movement of the element to be dimmed. By cooperating with the dimming element 130, the indicator 140 can accurately indicate the dimming angle of the headlight according to the movement of the dimming element 130. Thus, while dimming the headlight, the size of the dimming angle is indicated in real time, which facilitates the operator to accurately adjust the light output direction of the headlight.
[0044] It's important to understand that the light emission direction of a vehicle headlight can be characterized by the dimming angle. For example, when the light emission direction of the headlight is horizontal and needs to be adjusted to a 5-degree angle with the horizontal plane, the dimming indicator drives the dimming element inside the headlight to rotate around the dimming axis, thereby causing the dimming element to move and change the light emission direction. The dimming element may be a reflector or a module. Simultaneously with dimming, the indicator 140 displays the dimming angle in real time, so that when the indicator 140 shows the current dimming angle as 5 degrees, it means the light emission direction of the headlight has been accurately adjusted to 5 degrees.
[0045] Optional, such as Figure 1 and Figure 5 As shown, for ease of assembly, the housing 100 may include an upper housing 110 and a lower housing 120 that interlock to form an inner cavity 101. During installation, the indicator 140 and the dimming element 130 may be installed in the inner cavity 101 of the housing 100 and extend out of the housing 100 as required.
[0046] The dimming indicator in this application can be externally mounted on the vehicle light. To improve stability during operation, a fixing part can be provided on the housing 100. Before adjusting the vehicle light through the dimming indicator, the dimming element 130 is aligned with the element of the vehicle light to be dimmed and a driving relationship is established. Then, the housing 100 is fixed to the vehicle light by the fixing part before operation. Figure 1 As shown, the fixing part can be a fixing hole 121 provided in the lower housing 120. The fixing hole 121 can be used with screws, that is, the dimming indicator and the vehicle light are fixed by screwing the screw through the fixing hole 121 and screwing it into the vehicle light. Of course, in other embodiments, the fixing part can also be provided in the upper housing 110. In addition, the fixing part can also adopt other components such as clips that can achieve detachable connection with the vehicle light.
[0047] To facilitate the operator's movement of the device to be dimmed around the dimming axis via the dimming element 130, corresponding through holes 115 can be provided on the upper housing 110 and the lower housing 120. Thus, when the dimming element 130 is rotatably mounted on the housing 100, its opposite ends protrude from the two through holes 115. One protruding end of the dimming element 130 is used to establish a drive with the device to be dimmed, while the other end is used for operator operation. In some embodiments, such as... Figure 5 As shown, the upper end of the dimming component 130 can be an internal hexagonal column 131 and the lower end can be an external hexagonal column 132. The internal hexagonal column 131 at the upper end is used to adapt to the dimming tool of the operator, and the external hexagonal column 132 at the lower end is used to match the internal hexagonal column of the component to be dimmed, so as to realize the connection between the dimming indicator and the component to be dimmed.
[0048] Optionally, the cooperation between the dimming element 130 and the indicator 140 can be achieved through an electronic sensor or a mechanical transmission. For example, when using an electronic sensor, such as... Figure 10As shown, the dimming element 130 is rotatably mounted on the housing 100. The dimming element 130 has a gear section with multiple teeth. Correspondingly, the indicator 140 may include a photoelectric sensor, a controller, and a display connected in sequence. The photoelectric sensor is matched with the gear section. When the dimming element 130 is driven to rotate by an external force, the dimming element 130 drives the object to be dimmed to rotate synchronously. At the same time, the gear section mounted on the dimming element 130 also rotates synchronously. Since there is the same spacing between adjacent teeth, the teeth on the gear section will pass through the photoelectric sensor sequentially as the dimming element 130 rotates. The rotation angle is quantified according to the teeth on the gear section. For example, each time a tooth on the gear section passes through the photoelectric sensor, it represents that the dimming element 130 has rotated 1 degree. Of course, in other embodiments, it can also represent any degree such as 2 degrees or 3 degrees. Thus, the controller can determine the rotation angle of the dimming element 130 based on the number of teeth passing through the photoelectric sensor and the rotation angle represented by each tooth, and then determine the dimming angle and display it on the display for easy observation by the operator.
[0049] For example, when implemented through mechanical transmission, such as Figure 1 As shown, a scale 111 is provided on the housing 100 to cooperate with the indicator 140. The scale 111 may include multiple graduations, each representing a dimming angle. The indicator 140 is movably connected to the housing 100, and the dimming element 130 is driven to cooperate with the indicator 140, facilitating synchronous movement of the dimming element 130 and the indicator 140. Thus, when the operator dims the light, a force is applied to the dimming element 130, causing it to rotate around the dimming axis, while simultaneously moving the indicator 140 relative to the housing 100. This indicates the current dimming angle by aligning it with different graduations on the scale 111. This method of indicating the dimming angle through the synchronous movement of the dimming element 130 and the indicator 140 ensures display accuracy while avoiding the dimming indicator's dependence on a power source.
[0050] For example, the indicator 140 is rotatably connected to the housing 100, and the scale 111 is set along the rotation path of the indicator 140. Thus, when the operator adjusts the dimming, a force is applied to the dimming element 130, causing the dimming element 130 to rotate while simultaneously rotating the element to be dimmed, and also causing the indicator 140 to rotate relative to the housing 100. This indicates the current dimming angle by aligning it with different graduations on the scale 111. Displaying the dimming angle through rotation effectively reduces the size of the dimming indicator; however, the rotation display is limited by the number of rotations of the dimming element 130, resulting in a smaller range of dimming angles that can be displayed, making it suitable for small-angle dimming.
[0051] For example, the indicator 140 is slidably disposed on the housing 100, specifically, as shown in... Figure 1 or Figure 14As shown, a groove 112 is provided on the housing 100, and the indicator 140 is slidably disposed within the groove 112. Thus, when the dimming component 130 rotates, it synchronously drives the indicator 140 to slide within the groove 112. That is, through the driving connection between the dimming component 130 and the indicator 140, the conversion between rotation and translation is achieved. The scale 111 is located on at least one side of the groove 112 and is positioned along the sliding direction of the indicator 140 or the extending direction of the groove 112, so as to conveniently indicate the current dimming angle by aligning the indicator 140 with the scale at different positions on the scale 111 during the sliding process. When the indicator 140 uses a sliding method to display the dimming angle, it is not limited by the number of rotations of the dimming component 130 and can display a wide range of dimming angles. Figure 2 As shown, scales 111 are provided on both sides of the slide groove 112. The scales on the two scales 111 can be exactly the same or the scales can be staggered. This makes the smallest unit of the scales 111 more refined and can display the dimming angle more precisely.
[0052] In some implementations, such as Figure 14 The diagram shows a cross-sectional structure of a dimming indicator. The dimming element 130 is a screw rotatably mounted within the housing 100. One end of the screw is driven by a dimming shaft, while the other end is used for operator operation. The indicator 140 is directly threaded to the screw, and its sliding connection with the housing 100 creates a lead screw drive structure. A scale 111 is positioned along the axial direction of the dimming element 130. When the operator dims the light, a force is applied to the dimming element 130, causing it to rotate and simultaneously rotate the element to be dimmed. Simultaneously, the indicator 140 slides within the groove 112. During this sliding process, the indicator 140 aligns with different graduations on the scale 111 to indicate the current dimming angle.
[0053] In some embodiments, the dimming indicator further includes a transmission member 150. The dimming member 130 is rotatably mounted on the housing 100, and the dimming member 130 can be driven to connect with the indicator 140 via the transmission member 150. Thus, using the transmission member 150 as an intermediary ensures synchronous transmission between the dimming member 130 and the indicator 140, while simultaneously connecting different motion forms of the dimming member 130 and the indicator 140 (e.g., converting the rotation of the dimming member 130 into the translation of the indicator 140). It also improves the flexibility of the dimming member 130 and the indicator 140 when arranged on the housing 100. For example, to facilitate operation of the dimming member 130, the distance between the dimming member 130 and the indicator 140 can be increased via the transmission member 150. Another example is that to facilitate observation of the dimming angle indicated by the indicator 140 while operating the device, the transmission member 150 can be used to position the operating end of the dimming member 130 and the indicator 140 on the same side of the housing 100. Figure 1 As shown, the dimming element 130, which is used for operation by the operator, and the indicator 140 are both located on the top surface of the upper housing 110.
[0054] In one implementation, such as Figure 4 and Figure 5 As shown, the indicator 140 is slidably disposed in the slide groove 112, the dimming component 130 is rotatably disposed in the housing 100 and has a first bevel tooth portion 133 on the outer periphery of the dimming component 130, the transmission component 150 is a screw, the screw is rotatably disposed in the housing 100, the axial direction of the screw is approximately perpendicular to the axial direction of the dimming component 130, the end of the screw has a second bevel tooth portion 151 that meshes with the first bevel tooth portion 133, the two form a bevel gear pair, thereby realizing the conversion of the rotation direction, and the indicator 140 is threadedly connected to the screw. Therefore, when the operator adjusts the brightness, the dimming component 130 is driven to rotate. Through the meshing transmission of the first bevel gear 133 and the second bevel gear 151, the screw is driven to rotate. Since the indicator 140 cooperates with the screw to form a lead screw drive, the indicator 140 slides along the axial direction of the screw within the slide groove 112. During the sliding process of the indicator 140, it indicates the current dimming angle by aligning with the scales at different positions on the scales 111 on both sides of the slide groove 112. Please refer to [link / reference]. Figure 4 , Figure 5 , Figure 7 and Figure 8 When the transmission component 150 is a screw, opposing arc-shaped grooves 122 are respectively provided on the inner wall of the upper housing 110 and the inner wall of the lower housing 120. The two arc-shaped grooves 122, when joined together, form a rotating hole to accommodate the end of the screw. Correspondingly, two rotating holes are provided, each engaging with one of the two ends of the screw, thereby enabling the screw to rotate relative to the housing 100. Figure 4As shown, in order to ensure the stability of the screw rotation, an annular plate 152 is also provided on the peripheral wall of the screw end. During the rotation of the screw, the annular plate 152 is limited between the first bevel tooth 133 and the limiting protrusion 1141 on the housing 100, thereby ensuring that the screw only rotates and does not undergo axial displacement.
[0055] In one embodiment, the dimming element 130 is a worm gear rotatably mounted on the housing 100. One end of the worm gear is used to drive the dimming element, while the other end is used for operator operation. The transmission element 150 is a screw rotatably mounted on the housing 100. The end of the screw has a worm gear that meshes with the worm gear. The worm gear and worm wheel mesh to form an interlocking gear pair. The indicator 140 is threadedly connected to the screw to form a lead screw drive. Thus, when the operator dims the light, the worm gear is driven to rotate, which in turn drives the screw to rotate via the worm gear and worm gear. Since the indicator 140 and the screw form a lead screw drive, the indicator 140 slides along the axial direction of the screw within the groove 112. During the sliding process, the indicator 140 aligns with the scales at different positions on the scales 111 on both sides of the groove 112 to indicate the current dimming angle.
[0056] In one embodiment, the dimming element 130 has a first tooth, and the transmission element 150 is a rack with a second tooth. The first tooth and the second tooth mesh, the rack is slidably disposed on the housing 100, and the indicator 140 is fixedly disposed on the rack. Thus, when the operator adjusts the dimming, the dimming element 130 is driven to rotate. Through the meshing transmission of the first tooth and the second tooth, the rack is driven to slide relative to the housing 100. Since the indicator 140 is fixedly disposed on the rack, the indicator 140 slides in the same direction as the rack slides within the groove 112. During the sliding process of the indicator 140, the current dimming angle is indicated by aligning with the scales at different positions on the scales 111 on both sides of the groove 112.
[0057] Optionally, to improve the accuracy of the indication of indicator 140, such as Figure 1 , Figure 2 , Figure 6 and Figure 11 As shown, the indicator 140 can also have a pointer portion 142, and the tip of the pointer portion 142 can more accurately indicate the scale in the scale 111, thereby facilitating accurate light adjustment by the operator.
[0058] It's important to understand that headlights are dimmed before leaving the lighting factory. After the headlights are installed on the vehicle by the OEM, they need to be dimmed again according to the vehicle model to adapt to the vehicle. To prevent the indicator 140 in the dimming indicator from moving when the headlights are dimmed before leaving the factory, the driving engagement between the indicator 140 and the dimming element 130 can be disengaged. That is, the driven part on the indicator 140 is disconnected from the driving connection between the dimming element 130 or the transmission element 150. At this time, even if the dimming element 130 moves, the indicator 140 will not move with it. To prevent the indicator 140 from falling off during transportation, a snap-fit part can be provided on the indicator 140. When the indicator 140 and the dimming element 130 are disengaged, the indicator 140 is snapped into the housing 100 through the snap-fit part. When the OEM needs to dim the headlights, the indicator 140 can be driven to disengage the snap-fit part from the housing 100, and the indicator 140 can be driven to establish a drive with the dimming element 130 through the driven part. Thus, the synchronous movement of the dimming element 130 and the indicator 140 is achieved.
[0059] For example Figure 1 and Figure 3 As shown, the top of the indicator 140 is a pressing part 141. At this time, the snap-fit part of the indicator 140 snaps into the housing 100, and the driven part of the indicator 140 disengages from the transmission member 150 (screw). That is, the indicator 140 is disengaged from the dimming member 130, and the indicator 140 will not move with the dimming member 130. Figure 3 As shown, the snap-fit part can be two elastic snap-fit feet 144 arranged opposite to each other, which snap-fit with the housing 100.
[0060] like Figure 3 As shown, the driven part consists of two opposing spring pieces 143, one end of which is fixedly connected to the pressing part 141. Two elastic locking feet 144 can be connected to the other ends of the two spring pieces 143 respectively. The ends of the two spring pieces 143 near the screw have a gap, and internal threads matching the screw are respectively provided on the inner walls of the two spring pieces 143. When it is necessary to achieve transmission between the indicator 140 and the screw to ensure synchronous movement between the indicator 140 and the dimming element 130, the pressing part 141 of the indicator 140 can be pressed, such as... Figure 12 As shown, as the indicator 140 is pressed into the housing 100, the two elastic locking feet 144 deform and disengage from the housing 100. At the same time, the screw is positioned between the two elastic pieces 143 through the gap between the two elastic pieces 143. With the restoring deformation force of the two elastic pieces 143, the internal threads on the inner walls of the two elastic pieces 143 form a threaded engagement with the screw. Thus, when the dimming element 130 drives the screw to rotate, it simultaneously drives the indicator 140 to slide relative to the housing 100.
[0061] Optional, such as Figure 11As shown, in order to ensure that the indicator 140 can be pressed into the housing 100 and match the initial scale position in the scale 111, such as zero scale alignment, a mating part can be provided on the housing 100. The mating part can be a positioning groove 113 that communicates with the slide groove 112. When the indicator 140 is engaged with the groove wall of the positioning groove 113 by the two elastic locking feet 144, the two groove walls of the positioning groove 113 distributed along the extension direction of the slide groove 112 can be used to abut and limit the indicator 140. At this time, the indicator 140 matches the initial scale position in the scale 111.
[0062] Optionally, to prevent the two springs 143 of the indicator 140 from separating from the screw when adjusted to the limit position, causing over-adjustment, such as... Figure 7 and Figure 8 As shown, a limiting portion 114 is also provided on the upper housing 110. The limiting portions 114 are located at opposite ends of the slide groove 112. The limiting portion 114 includes a limiting protrusion 1141 for forming an arc-shaped groove 122 and abutting protrusions 1142 distributed on both sides of the slide groove 112, as shown. Figure 11 and Figure 13 As shown, when the indicator 140 moves to the end of the slide groove 112, i.e., the limit position, the indicator 140 can abut against the limiting protrusion 1141, restricting the indicator 140 from continuing to move in the same direction along the screw axis. At the same time, the two abutting protrusions 1142 abut against the two spring pieces 143 respectively, preventing the two spring pieces 143 from moving in opposite directions (i.e., Figure 13 The deformation (in the direction perpendicular to the screw axis) causes the threaded connection with the screw to disengage, resulting in slippage. Therefore, the threaded connection between the indicator 140 and the screw can be used to prevent the screw from continuing to rotate in the same direction, and consequently, also prevent the dimming element 130 from continuing to rotate in the same direction. It should be understood that "in the same direction" here means that the same component always moves in the same direction.
[0063] like Figure 15As shown, when using the dimming indicator to dim the vehicle lights, the dimming element 130 needs to establish a drive connection with the element to be dimmed through the dimming connection system 20. When the dimming connection system 20 is composed of a dimming screw 230, a dimming nut 231, a first dimming bevel gear 210, and a second dimming bevel gear 220, and the transmission component 150 of the dimming indicator 10 is a screw, when the dimming element 130 is driven to rotate by the screw through the first bevel gear 133 and the second bevel gear 151, the dimming element 130 rotates under the drive, passing through the first bevel gear 133 and the second bevel gear 151. Part 133 and the second bevel tooth part 151 drive the screw to move the indicator 140. On the other hand, the first dimming bevel tooth part 210 and the second dimming bevel tooth part 220 drive the dimming screw 230 to rotate, thereby causing the dimming nut 231 to translate and push the dimming bracket 240, which is equipped with a reflector or module, to rotate around the dimming axis with the line connecting another dimming nut 231 (not shown in the figure) and the fulcrum nut as the dimming axis. The relationship between the dimming angle α and the displacement of the indicator 140 can be calculated by the following formula:
[0064]
[0065] Wherein, T is the displacement of indicator 140; a is the dimming angle; c is the number of teeth of the second conical tooth 151; d is the number of teeth of the first conical tooth 133; e is the number of teeth of the first dimming conical tooth 210; f is the number of teeth of the second dimming conical tooth 220; P1 is the pitch of dimming screw 230; P2 is the pitch of transmission member 150 when it is a screw; and R is the dimming radius, which is the distance from the pushing point of dimming nut 231 to the edge of dimming bracket.
[0066] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
[0067] Industrial applicability
[0068] The dimming indicator of this application can drive the dimming element in the vehicle headlight while displaying the dimming angle in real time. This allows operators to accurately adjust the light output direction of the headlight, avoiding inaccuracies caused by factors such as the level indicator being affected by the vehicle's posture. The dimming indicator can be applied to automobiles, motorcycles, bicycles, ships, and other fields.
