Technical Field

[0001] This application relates to the field of vehicle parts technology, and more particularly to a lighting device, a seat, and a vehicle. Background Technology

[0002] As cars transform into multifunctional living spaces, users' demands for in-car lighting experiences are increasing. Currently, in-car lights are mainly fixed to the ceiling, using a top-down lighting method. However, this high-mounted installation can easily cause the light source to shine directly into the occupants' eyes, resulting in glare and discomfort, and may interfere with their vision. To improve this problem, some solutions place the light source on the side of the seat; however, the seat belt on the side of the seat can easily obstruct the light path, resulting in poor lighting effects and affecting the user's lighting experience.

[0033] To better understand the above-mentioned objectives, features, and advantages of this application, the solution of this application will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0034] Many specific details are set forth in the following description in order to provide a full understanding of this application, but this application may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of this application, and not all embodiments.

[0035] Reference Figures 1 to 8 As shown, a first aspect of this application provides a lighting device, including a main body 1, a light guide 2, and a light source 3; a mounting cavity 11 is formed in the main body 1, and the light source 3 is mounted in the mounting cavity 11; the light guide 2 is mounted on one side of the main body 1, and the light guide 2 includes a first segment 21 and a second segment 22 connected together, and a guide channel 23 is formed between the first segment 21 and the second segment 22; the first segment 21 is located between the second segment 22 and the mounting cavity 11, and the light emitted by the light source 3 shines on the first segment 21 and is conducted to the second segment 22 to provide illumination; the side of the main body 1 opposite to the light guide 2 is used for mounting on a seat 5, and the guide channel 23 is used for passing through the seat belt corresponding to the seat 5.

[0036] Specifically, seat belt guides are typically installed on the side of seat 5 to ensure the seat belt webbing passes through them and stays close to the seat. This also allows for adjustment of the seat belt webbing's position, preventing contact between the webbing and the occupant's neck. Because the side space of the seat is limited, and the seat belt webbing is also located on the side, if auxiliary lighting is installed on the side of the seat, the seat belt webbing can easily obstruct the lighting path, and interference can easily occur between the auxiliary lighting and the seat belt guide, affecting the lighting effect of the auxiliary lighting. The lighting device provided in this application embodiment has a guide channel 23 on the light guide 2 that can guide and limit the seat belt. The light source 3 emits light to the light guide 2, causing the second segment 22 located on the side of the seat belt facing away from the seat 5 to emit light to achieve illumination. The seat belt will not affect the lighting effect of the lighting device. The lighting device on the side of the seat 5 is located below the occupant's head, avoiding the light emitted by the lighting device from stimulating the eyes of the occupant and driver. The light guide 2 can also serve as a seat belt guide to limit and guide the seat belt, so that the lighting device integrates the functions of lighting and seat belt guidance, improving the occupant's user experience.

[0037] The main body 1 can be a block structure with a hollow interior, serving as a mounting cavity 11. The top of the main body 1 can have a light-transmitting window, with the light guide 2 installed on top of the main body 1 opposite the window. Alternatively, a portion of the first segment 21 can enter the mounting cavity 11 through the light-transmitting window, allowing the light emitted by the light source 3 to illuminate the first segment 21. Alternatively, the main body 1 can be a cylindrical structure, with the light guide 2 installed at one end of the cylindrical structure, so that the first segment 21 is at the end of the cylindrical structure, allowing the light emitted by the light source 3 to illuminate the first segment 21.

[0038] The light guide 2 mentioned above can be a transparent component made of plastic. The first segment 21 and the second segment 22 are two opposite parts of the light guide 2. The first segment 21 and the second segment 22 can both be arc-shaped plates. The two ends of the first segment 21 and the two ends of the second segment 22 are connected to each other, so that the first segment 21 and the second segment 22 are connected to form a cylindrical structure. The space between the first segment 21 and the second segment 22 forms a guide channel 23.

[0039] Alternatively, the first segment 21 and the second segment 22 can be rectangular plates, with the two ends of the first segment 21 and the two ends of the second segment 22 connected to each other through a transparent plate, so that the first segment 21 and the second segment 22 form a rectangular cylindrical structure, and the space between the first segment 21 and the second segment 22 forms a guide channel 23.

[0040] The light source 3 can be selected to include a battery and a lamp panel. The lamp panel is set in the mounting cavity 11 facing the first segment 21. After the battery supplies power to the lamp panel, the lamp panel emits light towards the first segment 21. After the first segment 21 receives the light, the light propagates in the first segment 21 to the second segment 22. The overall brightness of the second segment 22 increases and it emits light outward, so that the light emitted by the second segment 22 illuminates the space in front of the seat 5.

[0041] A switch can be installed on the outside of the main body 1. The switch is electrically connected to the light source 3 so that the switch can control the light source 3 to turn on and off. Alternatively, a controller can be installed on the main body 1. The controller is electrically connected to the light source 3 and the vehicle's on-board controller so that the occupant can drive the controller to turn the light source 3 on and off by sending a signal to the on-board controller. As long as the occupant can control the light source 3 to turn on and off, it is acceptable.

[0042] Seat 5 can be selected as a rear seat or a front seat of the vehicle. The main body 1 can be installed on the shoulder area of ​​seat 5. The seat belt webbing corresponding to seat 5 is threaded through guide channel 23, allowing the seat belt to be close to the occupant on seat 5. Optionally, the second segment 22 can have a notch, through which the seat belt webbing can enter and exit guide channel 23; alternatively, one end of the second segment 22 can be rotatably connected to the first segment 21, and the other end can be detachably connected to the first segment 21 via a buckle. When the buckle of the second segment 22 is separated from the first segment 21, the second segment 22 rotates relative to the first segment 21, allowing the seat belt webbing to enter the space between the first segment 21 and the second segment 22. After the buckle of the second segment 22 is connected to the first segment 21, the first segment 21 and the second segment 22 can restrict the position of the seat belt webbing, keeping the seat belt webbing close to seat 5.

[0043] Alternatively, the first segment 21 and the second segment 22 can be connected to each other. During vehicle production and assembly, the seat 5 and the lighting device are first installed inside the vehicle. An assembly component for installing the seat belt is set up inside the vehicle. After the seat belt webbing is passed through the guide channel 23, the two ends of the seat belt webbing are connected to the assembly component.

[0044] When the seat belt webbing is threaded through the guide channel 23, the second section 22 is on the side of the webbing facing away from the seat 5, that is, the second section 22 is exposed on the surface of the seat 5 and is not blocked by the seat belt; the light emitted by the light source 3 is transmitted to the second section 22, and the brightness of the second section 22 is increased, thus achieving the lighting effect.

[0045] In specific use, the lighting device provided in this application embodiment is installed on the seat 5, and the seat belt webbing passes through the guide channel 23. After the occupant sits on the seat 5, the seat belt is connected to the buckle on the side of the seat cushion of the seat 5. The seat belt webbing is restricted by the first section 21 and the second section 22 so that it can be close to the occupant. After the light source 3 is turned on, it emits light to the first section 21. The light received by the first section 21 is transmitted to the second section 22, and the overall brightness of the second section 22 is increased, thus playing a lighting role.

[0046] The lighting device provided in this application has a main body 1 mounted on the seat 5, a light guide 2 mounted on the main body 1, and a light source 3 located in the mounting cavity 11 within the main body 1. The seat belt webbing passes through the guide channel 23. The light emitted by the light source 3 illuminates the light guide 2, and the overall brightness of the light guide 2 increases after receiving the light for illumination. The light emitted by the light source 3 is conducted through the first section 21 to the second section 22, which is away from the area obstructed by the seat belt, causing the second section 22 to emit light outward for illumination, thus avoiding the seat belt from blocking the lighting path. At the same time, the lighting device is mounted on the side of the seat 5, and the light-emitting position of the light guide 2 is lower than that of a traditional ceiling light, effectively avoiding glare caused by direct light shining into the eyes, improving the lighting effect and passenger comfort. In addition, the guide channel 23 is provided on the light guide 2, giving the lighting device the dual functions of seat belt guidance and positioning as well as area lighting, solving the problem of equipment interference caused by insufficient space on the side of the seat.

[0047] Reference Figures 1 to 6 As shown, in some embodiments, the light guide 2 is provided with a mounting notch 24 communicating with the guide channel 23, so that the seat belt can enter and exit the guide channel 23 through the mounting notch 24; the main body 1 is provided with a base 4 (e.g., on the side opposite to the light guide 2) Figure 6 As shown, the base 4 is detachably connected to the main body 1, and the base 4 is fixed to the seat 5.

[0048] With this design, the seat belt can be easily removed from the guide channel 23 through the installation notch 24, facilitating the assembly and disassembly of the seat belt and lighting components.

[0049] Specifically, the mounting notch 24 can be a U-shaped opening formed on the side wall of the second section 22. The opening extends through the second section 22 along the extension direction of the guide channel 23 and also extends radially through the side wall of the second section 22, forming a notch structure on the light guide 2. The seat belt webbing passes through the mounting notch 24 and enters the guide channel 23, facilitating the assembly of the seat belt and the lighting device. Driving the seat belt webbing relative to the main body 1 allows the seat belt webbing to leave the guide channel 23 through the mounting notch 24, facilitating the maintenance or replacement of the lighting device.

[0050] Reference Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, the light guide 2 has a cylindrical structure, and the mounting notch 24 is formed on the second segment 22.

[0051] With this design, the light guide 2 is cylindrical, with its side walls all being curved plates. This minimizes light loss as it propagates through the cylindrical structure of the light guide 2 and prevents light leakage at sharp corners, ensuring uniform overall light emission in the second segment 22. Furthermore, the absence of sharp corners in the cylindrical structure prevents scratches to occupants or snagging on their clothing.

[0052] Specifically, the cross-sectional shape of the light guide 2 in the direction perpendicular to the guide channel 23 can be either circular or elliptical, with the major axis of the ellipse parallel to the side of the main body 1 away from the seat 5. The first segment 21 and the second segment 22 of the light guide 2 are both arc-shaped plates, which are arranged opposite to each other and protrude in a direction away from each other. The mounting notch 24 is formed on the second segment 22 to facilitate the driving of the seat belt through the mounting notch 24 to enter and exit the guide channel 23.

[0053] The light guide 2 can be a transparent plate with both ends bent toward each other and the two ends of the plate spaced apart to form an installation notch 24, so that the first section 21 and the second section 22 are an integrated structure; or the block structure can be drilled with through holes and the installation notch 24 can be machined on the side wall of the through holes by cutting, so that the block structure forms the light guide 2.

[0054] Reference Figures 1 to 3 As shown, in some embodiments, the main body 1 is provided with a base 4 on one side away from the light guide 2. The base 4 is detachably connected to the main body 1 and is fixed to the seat 5.

[0055] With this configuration, after the main body 1 is separated from the base 4, the main body 1 and the light guide 2 can move freely as a portable lighting device, so that the lighting device can flexibly adapt to the lighting needs of the occupants.

[0056] Specifically, the base 4 is located on the bottom side of the main body 1. The side of the base 4 facing the main body 1 may have a buckle, and the side of the main body 1 facing the base 4 may have a slot. The base 4 is fixed to the seat 5 by bolts or rivets. After the main body 1 is attached to the base 4, the buckle and slot engage, allowing the main body 1 to be detachably mounted on the base 4. Alternatively, the base 4 and the main body 1 may be detachably connected via a magnetic attraction mechanism.

[0057] When the main body 1 is installed on the base 4, the seat belt webbing is threaded through the guide channel 23, and the light guide 2 has the function of restricting and guiding the seat belt. When the main body 1 is separated from the base 4, the seat belt is released from the guide channel 23 through the mounting notch 24, allowing the main body 1 and the light guide 2 to move freely as a portable lighting device. The occupant can hold the portable lighting device formed by the main body 1 and the light guide 2 to illuminate other locations inside the vehicle, so that the lighting device can flexibly adapt to the user's lighting needs.

[0058] When the occupant holds the main body 1 and the light guide 2, the occupant's fingers can pass through the guide channel 23, allowing the occupant to grasp the main body 1, and the second segment 22 of the light guide 2 illuminates the outside of the user's fingers.

[0059] In some embodiments, the main body 1 is provided with a first magnetic attraction part, and the base 4 is provided with a second magnetic attraction part. The first magnetic attraction part and the second magnetic attraction part are magnetically connected so that the main body 1 is detachably connected to the base 4.

[0060] With this configuration, the magnetic attraction and separation of the first and second magnetic attraction parts are simple and convenient. When the main body 1 is close to the base 4, the magnetic force between the first and second magnetic attraction parts guides the main body 1, making it easy for the main body 1 to be accurately connected to the base 4.

[0061] Specifically, the first magnetic attraction part can be a magnet, and the second magnetic attraction part can be a magnetic metal block. After the main body 1 is attached to the base 4, the magnet and the metal block are magnetically connected, so that the main body 1 and the base 4 are detachably connected. Alternatively, the first magnetic attraction part can be a magnetic metal block, and the second magnetic attraction part can be a magnet, so that after the main body 1 is attached to the base 4, the magnet and the metal block are magnetically connected. Of course, both the first and second magnetic attraction parts can be magnets, with the first magnetic attraction part located on the side of the main body 1 facing the base 4, and the second magnetic attraction part located on the side of the base 4 facing the main body 1. When the main body 1 and the base 4 are attached, the first and second magnetic attraction parts are opposite to each other and attached to each other, and the magnetic poles on the opposite sides of the first and second magnetic attraction parts are opposite, so that the first and second magnetic attraction parts can be magnetically connected.

[0062] When the force exerted on the main body 1 by the base 4 is greater than the magnetic force between the first magnetic part and the second magnetic part, the main body 1 can separate from the base 4. The main body 1 can be attached to the base 4 so that the main body 1 can be installed on the base 4 through the magnetic connection of the first magnetic part and the second magnetic part, which facilitates the installation and disassembly of the main body 1 and the base 4.

[0063] In some embodiments, the base 4 is provided with a power supply unit, and the main body 1 is provided with a mounting port 111 communicating with the mounting cavity 11 on the side facing the base 4. When the main body 1 is connected to the base 4, the light source 3 and the power supply unit are electrically connected through the mounting port 111 so that the power supply unit can supply power to the light source 3.

[0064] With this configuration, when the main body 1 is mounted on the base 4, the power supply unit can supply power to the light source 3, enabling the light source 3 to emit light stably and avoiding the installation of exposed wires between the main body 1 and the base 4.

[0065] Specifically, the base 4 can optionally be equipped with a battery as a power supply unit, with the battery electrodes exposed on the base 4. The light source 3 has a connector exposed in the mounting port 111. When the main body 1 is installed on the base 4, the connector is connected to the electrodes so that the battery on the base 4 can supply power to the light source 3. Alternatively, the light source 3 can have a lamp panel and a battery, with a wireless charging module on the battery. The base 4 has a power supply coil, which can be connected to the vehicle's battery. After the main body 1 is installed on the base 4, the power supply coil is energized to supply power to the wireless charging module, allowing the wireless charging module to supply power to the battery.

[0066] Reference Figure 2 , Figure 4 and Figure 5 As shown, in some embodiments, the light source 3 includes a lamp board 31 and a battery 32. The battery 32 is provided with a first connector 321 exposed in the mounting port 111. The power supply unit forms a second connector on the side of the base 4 facing the main body 1. When the base 4 is connected to the main body 1, the first connector 321 is electrically connected to the second connector so that the power supply unit can supply power to the battery 32.

[0067] With this configuration, when the main body 1 is connected to the base 4, the power supply unit can supply power to the battery 32 so that the battery 32 is in a charging state; after the main body 1 is separated from the base 4, the battery 32 can continue to supply power to the lamp panel 31 so that the light guide 2 emits light, ensuring the battery life of the main body 1 and the light guide 2 when used as a portable lighting device.

[0068] Specifically, the lamp panel 31 may include a substrate and multiple light bulbs, which may be LED bulbs or other types of bulbs. The multiple bulbs are electrically connected to the substrate, and the substrate is electrically connected to the battery 32, so that the battery 32 can power the multiple bulbs. The lamp panel 31 may be positioned on the side of the battery 32 closer to the first segment 21, so that the battery 32 does not block the light emitted by the lamp panel 31 from illuminating the first segment 21.

[0069] Metal contacts can be optionally provided on the base 4 as a second connector, and metal contacts are provided on the side of the battery 32 facing the mounting port 111 as a first connector 321. When the main body 1 is installed on the base 4, the first connector 321 and the second connector are in contact with each other so that the power supply unit is electrically connected to the battery 32, and the power supply unit can supply power to the battery 32. That is, when the main body 1 is installed on the base 4, the battery 32 can be in a charging state.

[0070] The first connector 321 mentioned above can also be a plug, and the second connector can be a socket. When the main body 1 is installed on the base 4, the plug and socket are connected so that the power supply unit can directly supply power to the battery 32.

[0071] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, in some embodiments, the main body 1 is provided with a discharge interface 12, which is electrically connected to the battery 32 so that the battery 32 can output electrical energy to the outside through the discharge interface 12.

[0072] This configuration allows the lighting device to function as an emergency power source for electrical equipment, and in addition to being a portable lighting device, it can also act as a power bank to power devices such as mobile phones or tablets.

[0073] Specifically, a power transmission module can be installed inside the mounting cavity 11. The power transmission module is electrically connected to the battery 32. An opening is formed on the upper surface of the main body 1, and one side of the power transmission module is exposed in the opening. Different types of interfaces are provided on the surface of the power transmission module exposed in the opening, so that the opening and the power transmission module together form a discharge interface 12. Plugs of different signals can be connected to the power transmission module. After the external electrical equipment is connected to the power transmission module, the electrical energy stored in the battery 32 is transmitted to the external electrical equipment through the power transmission module.

[0074] Reference Figures 1 to 8 As shown, a second aspect of this application provides a seat, including a seat cushion, a backrest, and a lighting device as described in any of the preceding claims; the backrest is mounted on the seat cushion, and the main body 1 is mounted on the side of the backrest in the horizontal direction.

[0075] Specifically, the backrest is installed on the top side of the seat cushion. The area of ​​the backrest near the edge of the door in the horizontal direction is the side area. The main body 1 is installed on the side area. The main body 1 can be set in the middle of the backrest in the vertical direction, or it can be set in a position away from the seat cushion, as long as the guide channel 23 of the light guide 2 can guide and limit the seat belt, and the second section 22 can provide lighting in the side area of ​​the seat 5.

[0076] By using the above-mentioned lighting device on the seat, the lighting device can not only provide auxiliary lighting on the side of the seat 5, but also guide and restrict the seat belt. The lighting device integrates the functions of lighting and seat belt guidance, avoiding the problem of mutual interference between the auxiliary lighting and the seat belt guide.

[0077] Reference Figures 5 to 8 As shown, in some embodiments, the main body 1 is disposed at the top of the backrest.

[0078] With this configuration, the light guide 2 is positioned at the shoulder area near the backrest, so that the illumination area formed by the second segment 22 corresponds to the chest and waist area of ​​the occupant on the seat cushion, making it convenient for the occupant to read.

[0079] Specifically, the side of the backrest away from the seat cushion is the shoulder position of the backrest. The second segment 22 emits light at the shoulder position of the backrest to facilitate illumination of the area around the seat cushion.

[0080] A third aspect of this application provides a vehicle including a seat as described above.

[0081] Specifically, seat 5 can be positioned near the rear of the vehicle, serving as a rear seat. Alternatively, seat 5 can be positioned near the front of the vehicle, serving as the driver's seat or the front passenger seat.

[0082] When the above-mentioned seats are used in a vehicle, the lighting device on the side of seat 5 can both provide auxiliary lighting and guide and limit the seat belt.

[0083] When the lighting device, seat and vehicle provided in this application embodiment are used, the base 4 is installed at the shoulder position of the backrest, the main body 1 is attached to the base 4, the first magnetic part and the second magnetic part are magnetically connected, the first connector 321 is connected to the second connector, so that the power supply part supplies power to the battery 32, and the seat belt webbing enters the guide channel 23 through the installation notch 24.

[0084] After the occupant sits on the seat cushion, they connect the seat belt to the buckle on the seat cushion. The light emitted by the light panel 31 increases the brightness of the second section 22, so that the second section 22 illuminates the area in front of the occupant. When the occupant gets out of the vehicle or needs a portable lighting device while searching for something inside the vehicle, the occupant pulls the seat belt out of the guide channel through the mounting notch 24, and then moves the main body 1 to separate it from the base 4; the occupant's fingers pass through the guide channel 23 to grasp the main body 1 and use the second section 22 for illumination.

[0085] When an external electrical device needs emergency charging, connect the external electrical device to the discharge interface 12 so that the battery 32 can supply power to the external electrical device.
