[0002] With the continuous development of the automotive industry, consumers have increasingly higher demands for car interiors. Ambient lighting, as a device that can enhance the ambiance and driving experience inside the car, is mostly placed in easily noticeable areas such as the dashboard, door panels, and passenger side dashboard. Some models also include it in the wireless charging area. However, most ambient lighting only provides a basic effect to enhance the overall atmosphere of the vehicle, offering a limited range of visual appeal and failing to provide users with much more useful information. Utility Model Content

[0003] In view of the problems existing in the prior art, the present invention provides an indicator ambient light and vehicle to improve the problem that the existing ambient lights have a single presentation effect and cannot provide users with more effective information.

[0004] To achieve the above and other related objectives, the first aspect of this utility model provides an ambient indicator light installed inside a vehicle. The ambient indicator light includes a light source, a projection element, and a driving unit. The projection element includes multiple projection areas with projection patterns, and the light from the light source forms a preset pattern after passing through the projection areas. The driving unit is configured to drive the projection element to move according to the charging module status of the vehicle, thereby switching the projection areas located in the light path of the light source.

[0005] In an exemplary embodiment of the present invention, the driving unit drives the projection member to rotate; the projection member is provided with three projection areas, which are arranged on the same circumference, and the center of the circumference is located on the rotation axis of the projection member.

[0006] In an exemplary embodiment of this utility model, the three projection areas are arranged in a circular array.

[0007] In an exemplary embodiment of this utility model, the projection member includes a mounting portion, a projection portion, and a connecting portion. The mounting portion is connected to the driving portion; the projection portion is provided with the projection area; the connecting portion connects the mounting portion and the projection portion, and a plurality of the connecting portions are arranged along the outer periphery of the mounting portion.

[0008] In an exemplary embodiment of the present invention, the driving unit drives the projection member to move linearly, and the plurality of projection areas are arranged along the movement direction of the projection member.

[0009] In an exemplary embodiment of the present invention, the ambient light includes a first lens group, which is disposed between the light source and the projection member, so that the light beam of the light source is collimated and then enters the projection area.

[0010] In an exemplary embodiment of the present invention, the ambient light includes a second lens group, which is disposed on the side of the projector away from the light source to magnify and project the pattern of the projection area onto the illumination area, which is located in the charging module area of ​​the vehicle.

[0022] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be noted that, in the absence of conflict, the following embodiments and features in the embodiments can be combined with each other. It should also be understood that the terminology used in the embodiments of this utility model is for describing specific implementation schemes and not for limiting the scope of protection of this utility model.

[0025] Most existing ambient lights are placed in easily noticeable locations such as the dashboard, door panels, and passenger side dashboard. Some models also place them in the wireless charging area. However, these only provide an effect to enhance the atmosphere inside the car, and the effect is limited and cannot provide users with more effective information.

[0026] For example, the ambient lighting in existing wireless charging areas usually only creates an atmosphere or has a breathing / flickering effect, but it does not provide any indication of the charging status. This forces drivers to turn on their phone screens to see the charging status, which can affect their operation and make it inconvenient for them to use.

[0027] In view of this, the present invention provides an ambient light indicator. A driving unit moves a projection element, causing different projection areas to move to the light source, thereby forming different preset patterns in the illuminated area. These preset patterns can be text, images, or a combination of both. This allows for the display of different colored lighting atmospheres as needed, and also provides different status indications based on the patterns. For example, the illuminated area of ​​the ambient light indicator can be located in the charging area. The ambient light indicator is directly or indirectly electrically connected to the charging module, and different preset patterns indicate different charging statuses. The preset patterns can also include text, such as "Charging" or "Charging Complete" in different projection area patterns. This allows the driver to clearly and intuitively see the phone's charging status without needing to turn on the phone. It can both enhance the atmosphere and create different moods, and also display status information as needed, providing practical information indications, enriching the usage effect of ambient lights, expanding their application scenarios, and facilitating the creation of differentiated products.

[0028] Please see Figures 1 to 3 The first aspect of this utility model provides an ambient indicator light installed inside a vehicle. The ambient indicator light includes a light source 100, a projection element 200, and a driving unit 300. The projection element 200 includes multiple projection areas 221 with projection patterns. Light from the light source 100 passes through the projection areas 221 to form preset patterns, representing different status information. The preset patterns can be text, pictures, or a combination of text and pictures, and can be set according to actual needs. The driving unit 300 drives the projection element 200 to move according to the charging module status of the vehicle, switching the projection areas 221 located in the light path of the light source 100. After different projection areas 221 move to the light path of the light source 100, light passing through the projection areas 221 will form different preset patterns in the illuminated area. This allows users to easily obtain the corresponding information based on the preset patterns. The ambient indicator light can adjust the light effect of the light source 100 to create different atmospheres according to the scene, and can also display information as needed, enriching the display content of the ambient light and expanding its application scenarios.

[0029] Ambient indicator lights can be installed in different areas inside the vehicle, such as the passenger side, armrest, and center console, to create preset patterns and different colors of light in different illuminated areas. The illuminated areas can also be set in different locations, such as the passenger side, armrest, or charging module area. Preferably, the illuminated area is located in the charging module area, i.e., the area where the charging equipment is placed, to facilitate users in checking the charging status of the equipment.

[0030] Please see Figure 1 and Figure 2 In one embodiment, the driving unit 300 drives the projection member 200 to rotate, and the projection areas 221 are distributed at different positions on the projection member 200, so that when the projection member 200 rotates, the projection areas 221 can move to the path of the light from the light source 100 to form a predetermined pattern in a predetermined area. The driving unit 300 can be a rotation driving mechanism such as a motor, and the driving unit 300 and the projection member 200 can be directly connected, for example, the output shaft of the motor can be fixed to the projection member 200; alternatively, the driving unit 300 can be first connected to a reducer, and then the reducer can be connected to the projection member 200, so as to more easily adjust the rotation speed of the projection member 200 and the switching speed of the predetermined pattern.

[0031] The drive unit 300 drives the projection member 200 to move according to the charging module status of the vehicle. The drive unit 300 is directly or indirectly electrically connected to the charging module. The electrical connection can be wired or wireless, such as wireless communication. The charging module can obtain the charging status of the charging device. The drive unit 300 adjusts the projection member 200 according to the charging status of the charging device obtained by the charging module to form different preset patterns in the illumination area to display different charging statuses of the charging device. The charging status includes at least charging in progress, charging complete, and idle state.

[0032] The charging module can be a wired charging module, where the charging module connects to the charging device via a wire to charge the device; or it can be a wireless charging module, where the charging module charges the device without a wired connection, for example, using electromagnetic induction, where the charging module and the charging device transfer energy through a magnetic field. Of course, other optional wireless charging methods are also possible.

[0033] Please see Figure 2In one embodiment, the projection member 200 is provided with three projection areas 221, which are arranged on the same circumference. The center of the circumference is located on the rotation axis of the projection member 200. The driving unit 300 drives the projection member 200 to rotate in both directions by forward and reverse rotation, thereby enabling arbitrary switching between the three projection areas 221. For example, when an ambient light is installed in a wireless charging area, the three projection areas 221 can correspond to three states: charging, charging complete, and idle. The projection area 221 corresponding to the charging state has the words "Charging" displayed, thus displaying the text "Charging" in the illuminated area; the projection area 221 corresponding to the charging complete state has the words "Charging Complete" displayed, thus displaying the text "Charging Complete" in the illuminated area; and the projection area 221 corresponding to the idle state displays a pattern or is blank as needed, only creating a bright effect in the illuminated area. The three states can be switched freely between any two states, making the state switching simpler and more accurate. This avoids the need for other states to transition between two states, thereby effectively reducing the occurrence of mis-transmission of information and driver misidentification, and ensuring the accuracy of the information obtained by the driver.

[0034] Ambient lights can be installed above the wireless charging area, illuminating that area to ensure that even when items are placed there, a specific pattern is accurately formed, allowing the driver to quickly and accurately identify the current status. Ambient lights can also be installed in other easily visible areas for the driver to view the current charging status.

[0035] Please see Figure 2 In one embodiment, the three projection areas 221 are arranged in a circular array and at equal angles, so that when the driving unit 300 drives the projection member 200 to rotate, the switching time between the projection areas 221 is equal or substantially equal, thereby improving the smoothness of the switching of the projection areas 221 and improving the information transmission effect.

[0036] Of course, as an option, the three projection zones 221 can be arranged at unequal angles, depending on actual needs.

[0037] In one embodiment, at least one of the projection areas 221 is a blank projection pattern, meaning that only one area of ​​the irradiated area is illuminated, with no other patterns within that area. For example, when displaying mobile phone charging information, a blank projection pattern indicates an idle state, which can better enhance the atmosphere and prevent patterns from interfering with it. At this time, the light source 100 can still generate different colors of light as needed to create different atmospheres. The blank projection pattern can also illuminate the irradiated area to create a lighting effect, making it easier to identify the irradiated area or find items within it. For example, when the irradiated area is a wireless charging area, it is convenient for drivers to place their mobile phones or other electronic products to be charged in this wireless charging area for charging.

[0038] Please see Figure 2 In one embodiment, the projection member 200 includes a mounting portion 210, a projection portion 220, and a connecting portion 230. The mounting portion 210 is connected to the driving portion 300, the projection portion 220 is provided with the projection area 221, and the connecting portion 230 connects the mounting portion 210 and the projection portion 220. Multiple connecting portions 230 are arranged along the outer periphery of the mounting portion 210. By connecting the mounting portion 210 and the projection portion 220 with the connecting portion 230, the weight of the projection member 200 can be reduced while maintaining the overall strength of the projection member 200, thus reducing the power required by the driving portion 300, lowering costs, and increasing service life.

[0039] The mounting part 210 can be any shape, such as round, square or elliptical. Preferably, the mounting part 210 is a circular plate structure, so as to facilitate the arrangement of connecting parts 230 in a circular array on the outer periphery of the mounting part 210.

[0040] Of course, as some alternatives, the projector 200 can be a circular sheet structure to meet different usage requirements. The circular sheet structure can be perforated to reduce the weight of the projector 200, or it can be left unperforated.

[0041] In another embodiment, the drive unit 300 drives the projection member 200 to move linearly. Multiple projection areas 221 are arranged along the moving direction of the projection member 200. By driving the projection member 200 to move linearly back and forth, different projection areas 221 are switched to the position of the light source 100 to form different specific patterns in the irradiated area. The drive unit 300 can be a telescopic rod structure, such as an electric telescopic rod, to achieve the linear back and forth movement of the projection member 200. The drive unit 300 can also be a motor coupled with a ball screw structure to drive the projection member 200 to move linearly back and forth. The drive unit 300 can also be other components or mechanisms that achieve the linear back and forth movement of the projection member 200. The projection member 200 is elongated, and the projection areas 221 are arranged along the length of the elongated shape to facilitate switching of the projection areas 221. The projection areas 221 are arranged at equal intervals to facilitate control by the drive unit 300.

[0042] Of course, as some alternatives, the projection part 220 can be other shapes, and the projection area 221 can be arranged at unequal intervals, etc.

[0043] Please see Figure 1 and Figure 3 In one embodiment, the light source 100 is integrated on a PCBA 110 (Printed Circuit Board Assembly) to facilitate control of the light source 100. The PCBA 110 is connected to a connector 600 via leads, allowing the PCBA 110 to connect to an external host computer for control of the light source 100. For example, the PCBA 110 can be connected to a vehicle's host computer, and the light source 100 can be controlled via signals from the vehicle's host computer to display different information or adjust different atmospheres. The connector 600 is a 3-pin connector, including positive and negative terminals and a LIN receiver, which inputs color and brightness signals via LIN to change color and brightness.

[0044] The light source 100 can be an LED light source 100, an LCD light source 100, etc. Preferably, the light source 100 is an RGB LED light source 100, that is, an LED light that integrates the three primary colors to form an image. The brightness of each color LED can be adjusted to mix a wide spectrum, thereby achieving a variety of color and brightness changes, presenting a rich and colorful color effect, and meeting the needs of various atmosphere settings.

[0045] The light source 100 can adjust different colors as needed. For example, when illuminating any projection area 221, the light source 100 can still change colors according to the scene to create different atmospheres. It can also be used to correspond a specific color to a specific projection area 221 to facilitate more accurate information identification. Alternatively, it can be used to combine the method of corresponding a specific color to a specific projection area 221 in most projection areas 221 states, while allowing the color to be arbitrarily changed in a few projection areas 221 states, and select according to the needs of atmosphere creation and information transmission.

[0046] The drive unit 300 is electrically connected to the host separately. The host signal controls the drive unit 300 to achieve alignment of different projection areas with the power supply, making it convenient to use.

[0047] Of course, as an option, the drive unit 300 and the light source 100 can also share a controller to facilitate the coordinated operation of the drive unit 300 and the power supply.

[0048] Please see Figure 1In one embodiment, the ambient light includes a first lens group 400, which is disposed between the light source 100 and the projection element 200, so that the light beam from the light source 100 is collimated and then incident on the projection area 221. For example, the first lens group 400 includes two convex lenses with their convex surfaces facing each other, so as to converge and collimate the diverging light beam emitted by the light source 100 before it is incident on the projection area 221. The first lens group 400 can also be configured as a biconvex lens, a freeform lens, etc., as needed.

[0049] Please see Figure 1 In one embodiment, the ambient light includes a second lens group 500, which is disposed on the side of the projector 200 away from the light source 100 to magnify the pattern of the projection area 221 to the illumination area, which is located in the charging module area of ​​the vehicle, so as to make it easier for the user to view the charging status of the charging device.

[0050] In one embodiment, the second lens group 500 includes at least one concave lens to achieve the effect of beam expansion and pattern magnification. The second lens group 500 may also include a single convex lens, a biconvex lens, a freeform surface lens, etc., and the effect of magnifying and clarifying the projected pattern can be achieved by combining lenses.

[0051] In one embodiment, the projection member 200 is provided with a through hole, and a film is assembled in the through hole to form the projection area 221. Forming the projection area 221 with a film has the advantages of being easy to customize, easy to replace, high clarity, and good durability, which meets the needs of vehicle applications.

[0052] The ambient light includes a housing for assembling the drive unit 300, the projection unit 220, the light source 100, and other necessary components. The housing can assemble all the components of the ambient light, thereby making the ambient light a whole; it can also be used for assembling some components, with the remaining components assembled to the vehicle or other installation positions. Assembly methods include, but are not limited to, screw connection, glue connection, and snap-fit ​​connection.

[0053] Of course, as an option, ambient lighting can also be installed without a housing, with each component directly mounted in the desired location, such as on a vehicle.

[0054] A second aspect of this utility model provides a vehicle including a charging module and an ambient light as described in any of the above claims. The ambient light is directly or indirectly electrically connected to the charging module, allowing the ambient light to switch the projection area 221 at the path of the light source 100 according to the state of the charging module. The ambient light can be installed in different locations on the vehicle, such as doors, passenger side, armrest, or wireless charging area, to meet different indication needs. For example, if the ambient light is installed above the charging area, different patterns are formed by different projection areas 221, making it easy for the driver to know the current charging status of mobile phones or other charging devices.

[0055] The charging module can be either a wireless charging module or a wired charging module, with a wireless charging module being preferred.

[0056] The ambient indicator light and the charging module can be directly electrically connected, or they can be indirectly electrically connected through modules such as the vehicle infotainment system, so that the ambient indicator light can obtain the status of the charging module and then switch the projection area 221 at the path of the light source 100.

[0057] The electrical connection between the indicator ambient light and the charging module can be either a wired or wireless connection, enabling communication between the indicator ambient light and the charging module.

[0058] The ambient light of this application includes a projector 200 and a drive unit 300. The drive unit 300 drives the projector 200 to move, causing different projection areas 221 to move to the light source 100. This allows light from the light source 100 to be projected through the projection areas 221 to form different preset patterns, thus creating different status indication effects. The ambient light of this application can project different colors of light according to the scene to create different atmospheres, and can also set different preset patterns according to actual needs to provide effective status indication information. Therefore, this utility model effectively overcomes some practical problems in the prior art and has high utilization value and significance. The above embodiments are only illustrative of the principle and effect of this utility model and are not intended to limit this utility model. Any person skilled in the art can modify or change the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or changes made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
