[0032] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] The ordinal numbers used in this article, such as first and second, are used to distinguish different parts with the same name and do not indicate a specific order or primary / secondary relationship.

[0034] Please refer to Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of the cabin lights of a vehicle in one embodiment of this application; Figure 2 for Figure 1 A diagram illustrating the explosion of the lights inside the middle cockpit.

[0035] The cabin interior light provided in this embodiment is installed inside the vehicle's cabin, which includes the front driver's cabin and the rear passenger cabin. The cabin interior light can provide illumination for the driver or other users, such as when searching for items or checking equipment, and can also be used as a reading light. The cabin interior light can be installed on the cabin ceiling or in other locations. In this embodiment, the cabin interior light includes a lamp body assembly 50 and an outer lamp housing 20. The lamp body assembly 50 is located inside the outer lamp housing 20, and the lamp body assembly 50 and the outer lamp housing 20 are rotatably connected, meaning the lamp body assembly 50 can rotate relative to the outer lamp housing 20. The outer lamp housing 20 not only protects the lamp body assembly 50 but also shields it, visually concealing the rotation of the lamp body assembly and improving the user's perception of the cabin interior light.

[0036] In this embodiment, the outer lamp housing 20 specifically includes an outer lamp cover 202, an outer cover 201, and a cover plate 203. The outer lamp cover 202 has openings on opposite sides and is generally a cylindrical structure. The outer cover 201 seals one opening of the outer lamp cover 202, and the cover plate 203 seals the other opening of the outer lamp cover 202 to form a relatively closed outer lamp housing 20. The outer cover 201 faces the user. It can be understood that the lamp body assembly 50 has a light-emitting side, and at least the portion of the outer lamp housing 20 corresponding to the light-emitting side of the lamp body assembly 50 is made of a light-transmitting material so that light can be emitted to provide the required illumination. For example, if the outer cover 201 faces the user, then the outer cover 201 can correspond to the light-emitting side of the lamp body assembly 50. The outer cover 201 includes a light-emitting portion, which is used to transmit illumination light outward. Here, the outer lamp housing 20 is designed as a separate unit to facilitate the installation of the lamp body assembly 50 into the interior of the outer lamp housing 20. It can be seen that the structural form of the outer lamp housing 20 is not limited to this, as long as it does not interfere with the installation of the lamp body assembly 50. For example, the outer lamp housing 20 could also be a two-half-shell structure. The outer lamp cover 202 and the cover plate 203 are detachably connected. Figure 2 In the middle, the cover plate 203 is provided with a first snap-fit ​​part 2031 to snap and connect with the outer lamp cover 202, which is simple and reliable. At the same time, the cover plate 203 is also provided with a connection hole, which can be connected to the vehicle body by inserting a fastening screw 40 into the connection hole, so as to fix the cabin light to the vehicle body.

[0037] like Figure 2As shown, the cabin interior light in this embodiment also includes an outer decorative ring 10, which surrounds the aforementioned outer cover 201. The cabin interior light is, for example, embedded in the inner wall of the cabin, with the outer decorative ring 10 exposed so that the user can observe the position of the cabin interior light. The outer decorative ring 10 and the outer lamp housing 20 are detachably connected. The outer decorative ring 10 may be provided with a second snap-fit ​​portion 101, which can snap-fit ​​with the outer lamp cover 202. Simultaneously, the outer cover 201 can abut against the outer lamp cover 202, achieving relative fixation between the outer cover 201 and the outer lamp cover 202, making the connection simple and reliable. The outer decorative ring 10 has a window, and the outer cover 201 corresponds to the position of the window, thereby transmitting illumination light outward from the window position.

[0038] like Figure 3 As shown, Figure 3 for Figure 2 A schematic diagram of the structure of the central lamp body assembly 50.

[0039] In this embodiment, the lamp assembly 50 specifically includes an inner lamp housing 501, a first circuit board 502, and a lamp source (not shown in the figure due to perspective, but mounted on the first circuit board 502). The inner lamp housing 501 specifically includes an inner lamp shade 5011 and an inner cover 5012. The inner lamp shade 5011 has an opening on one side, and the inner cover 5012 can seal the opening of the inner lamp shade 5011 to form a relatively closed inner lamp housing 501. The first circuit board 502 is used to control the lamp source, and both the lamp source and the first circuit board 502 are located inside the inner lamp housing 501. The lamp assembly 50 in this embodiment further includes a light guide 503. The light guide 503 is used to guide the light from the lamp source to improve the uniformity of the light. The light guide 503 is also disposed inside the inner lamp housing 501 and can be connected to the inner cover 5012 to guide the light from the lamp source to the inner cover 5012, and then the light is transmitted from the inner cover 5012 to the outer cover 201, finally illuminating the outside to ensure the lighting effect. It can be seen that the inner lamp housing 501 is set separately, which makes it easier for the lamp source, the first circuit board 502, and the light guide 503 to be installed inside the inner lamp housing 501.

[0040] The lamp body assembly 50 in this embodiment also includes a rotating shaft 504. The lamp body assembly 50 is rotatably connected to the outer lamp housing 20 via the rotating shaft 504. The drive assembly 60 includes a motor 601, which can directly or indirectly drive the rotating shaft 504 to rotate, thus facilitating the rotation of the entire lamp body assembly 50. Specifically, the rotating shaft 504 is connected to the light guide 503. The inner lamp cover 5011 is provided with a rotating shaft hole 5011a. The rotating shaft 504 passes through the rotating shaft hole 5011a and is rotatably connected to the outer lamp housing 20, so that the entire lamp body assembly 50 can rotate relative to the outer lamp housing 20. The rotating shaft 504 is directly connected to the light guide 503, making the rotation of the lamp body assembly 50 more reliable.

[0041] like Figure 2 ,3 As shown, the cockpit light drive assembly 60 in this embodiment may further include a turntable 603, which is connected to the rotating shaft 504 via a transmission connection, for example, the turntable 603 and the rotating shaft 504 are coaxially fixedly connected or circumferentially limited connected. With this configuration, the motor 601 can drive the turntable 603 to rotate, and when the turntable 603 rotates, it drives the rotating shaft 504 to rotate, which in turn drives the lamp body assembly 50 to rotate. The transmission via the turntable 603 can increase torque to ensure the reliability of driving the lamp body assembly 50.

[0042] You can continue to refer to this. Figure 4 , Figure 4 for Figure 1 A cross-sectional view of the interior lights in the middle cockpit along the AA direction.

[0043] The drive assembly 60 in this embodiment may further include a drive shaft 602, which is rotatably connected to the output end of the motor 601, and the rotatable connection position is offset from the rotation center of the output end of the motor 601. The drive shaft 602 is rotatably connected to the turntable 603. Thus, when the motor 601 rotates, it drives the drive shaft 602 to rotate relative to it, and the drive shaft 602 pushes or pulls the turntable 603 to rotate, thereby driving the rotating shaft 504 to rotate. Defining the drive shaft 602 and motor 601 connected at a first rotatable connection position, and the drive shaft 602 and turntable 603 connected at a second rotatable connection position, the distance between the second rotatable connection position and the first rotatable connection position is greater than the distance between the center of the turntable 603 and the first connection position. This facilitates the pulling and pushing of the turntable 603 by the drive shaft 602. This structure of the drive shaft 602 is relatively simple and helps save space. It is understood that other methods can be used to achieve the transmission connection, such as setting the motor 601 and the rotating shaft 504 to transmit power through a gear assembly.

[0044] The drive assembly 60 may further include a second circuit board 80, which is signal-connected to the motor 601 to control the rotation of the motor 601. The second circuit board 80 is equipped with wiring 801 for connecting to a power source. The second circuit board 80 is installed inside the outer lamp housing 20. It can be understood that the circuitry of the first circuit board 502 can also be integrated onto the second circuit board 80, thus eliminating the need for the first circuit board 502 in the lamp assembly 50. However, for ease of connection, a separate first circuit board 502 can be provided for the lamp source.

[0045] Can continue to combine Figure 5-7 To understand the solution in this embodiment, Figure 5 for Figure 3 A schematic diagram of the structure in which the central lamp body assembly 50 rotates relative to the outer lamp housing 20 at a first angle; Figure 6 for Figure 3 A schematic diagram of the structure in which the central lamp body assembly 50 rotates at a second angle relative to the outer lamp housing 20; Figure 7 for Figure 3 A schematic diagram of the structure of the central lamp body assembly 50 rotating at a third angle relative to the outer casing.

[0046] The plane perpendicular to the outer cover is taken as the first reference plane S, and the plane perpendicular to the inner cover 5012 is taken as the second reference plane P. Figure 5 The light is positioned vertically, and the angle α between the second reference plane P and the first reference plane S is 0°, which is equivalent to the light being projected perpendicularly from the outer cover 201. Figure 6 It drives the lamp assembly 50 to rotate clockwise from its initial position. Figure 6 The angle α between the second datum plane P and the first datum plane S is -10°. Figure 7 It drives the lamp assembly 50 to rotate counterclockwise from its initial position. Figure 7 The angle between the second datum plane P and the first datum plane S is α = 40°. Figure 5-7 The diagram also uses dashed lines and arrows to illustrate the changes in the angle of the projected light. Considering the need to ensure a certain illumination range, the included angle α can be between -10° and 50°. Of course, the range of included angle α can be adjusted adaptively according to the installation angle of the cabin lights and adjustment requirements.

[0047] Therefore, the lamp assembly 50 in this embodiment can rotate, allowing the angle of the lamp assembly 50 to be adjusted according to actual usage needs, thereby adjusting the angle of the projected light to provide better illumination. With the development trend of multifunctional intelligent cockpits in vehicles and the widespread adoption of diverse spatial forms, the cockpit not only needs to fulfill driving and riding functions but should also assume a more comprehensive "third space" role, serving as a place for rest, entertainment, and light work. Therefore, users' activities within the cockpit are not limited to driving or riding. Because the lamp assembly 50 in this embodiment can rotate, it can provide comfortable lighting for users' needs such as reading and working, that is, it can adaptively adjust according to the user's activities and the needs of the scenario.

[0048] In practical use, motor 601 is connected to the vehicle's controller, which can be a BCM (Body Control Module, central controller). The vehicle also has a DMS (Driver Monitoring System), which is also connected to the controller. The DMS includes multiple cameras, such as IR (Infrared) cameras. The cameras capture the user's behavior in different locations, such as working, watching movies, searching for objects, reading, etc., and can transmit the signals to the controller. The controller outputs control signals to motor 601 according to the user's current behavior needs. Specifically, it outputs the signals to the second circuit board 80 that controls motor 601, so that motor 601 drives the lamp assembly 50 to rotate to a suitable angle.

[0049] Alternatively, the controller can connect to other electric devices in the vehicle's cabin, such as tray tables and seats. If it detects that the tray table is open, the seat is reclined, the seat is rotated, or a double bed mode is being used, it can transmit a signal to the controller via a sensor. The controller then transmits the signal to the second circuit board 80 of the motor 601, thereby driving the motor 601 to adjust the angle of the lamp assembly 50, achieving adaptive adjustment of the lamp assembly 50. For example, when the tray table is open, indicating that the user needs to use it, if the lamp assembly 50 is facing the seat, it can be rotated to face the tabletop to illuminate it. Similarly, in reclined, rotated, or double bed modes, the user's position and height change, and the required lighting angle changes accordingly. The lamp assembly 50 can be adjusted to rotate to match the user's lighting needs in the current seat mode.

[0050] In this way, the vehicle's smart cockpit hardware can be combined to enable the cockpit lights to work in tandem with other devices in the cockpit for interconnected and intelligent interaction, better serving users and creating a more comfortable and pleasant cockpit lighting environment.

[0051] Let's look again. Figure 2 and combined Figure 8 understand, Figure 8 for Figure 2 A schematic diagram showing the movement of the flexible inner support 30 and the lamp body assembly 50.

[0052] The cabin lamp in this embodiment also includes a flexible inner support 30, which is located inside the outer lamp housing 20. The flexible inner support 30 includes a cylindrical structure, and the lamp body assembly 50 has a light-emitting part, specifically, the inner cover 5012 of the lamp body assembly 50 has a light-emitting part. The light guided by the light guide 503 can be emitted from the light-emitting part of the inner cover 5012. Part or all of the inner cover 5012 can be a light-emitting part. The cylindrical structure has two ends distributed along the height direction of the cylinder, namely a first opening end 301 and a second opening end 302. The first opening end 301 is connected to the outer lamp housing 20, specifically it can be connected to the outer cover 201, for example, it can be arranged around the light-emitting part of the outer cover 201. The second opening end 302 is connected to the lamp body assembly 50, and the second opening end 302 is arranged around the light-emitting part of the lamp body assembly 50, specifically it can be arranged around the light-emitting part formed by the inner cover 5012. With this configuration, the second opening end 302 of the flexible inner support 30 can rotate with the rotation of the lamp body assembly 50, but the first opening end 301 of the flexible inner support 30 remains stationary relative to the outer lamp housing 20. Due to the nature of its flexible material, the flexible inner support 30 can undergo corresponding deformation, such as expansion and contraction. Thus, if viewed from the light-emitting side of the outer lamp housing 20, only the light-emitting portion surrounding the lamp body assembly 50 can be observed. Figure 8As shown, other parts of the lamp body assembly 50 and other components inside the outer lamp housing 20 are shielded by the flexible inner bracket 30. Thus, regardless of how the lamp body assembly 50 rotates, the user cannot observe any parts other than the light-emitting portion of the lamp body assembly 50, nor any other structures inside the outer lamp housing 20, ensuring a good visual effect. The flexible inner bracket 30 can be, for example, a cylindrical structure made of rubber, or a corrugated pipe-like structure. Of course, the material of the flexible inner bracket 30 should, as far as possible, not affect the outward projection of light.

[0053] in addition, Figure 2 In this embodiment, a touch-sensitive diaphragm 70 can be installed inside the outer lamp housing 20, specifically at the position of the outer cover 201. This facilitates user touch control, and the touch-sensitive diaphragm 70 enables the lamp assembly 50 to be a touch-sensitive lamp, making it easy for users to turn the light source on and off. In this embodiment, the lamp assembly 50 can have dual light output functions, serving as both a floodlight and a projector.

[0054] In this embodiment, the cabin lights, in addition to being able to rotate, can also be turned on / off / rotated via voice LIN (Local Interconnect Network) communication signals or HU (Head Unit, in-vehicle entertainment system) large screen operation, so as to improve operational flexibility and adapt to the current smart cockpit.

[0055] This document uses specific examples to illustrate the principles and implementation methods of this application. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core ideas of this application. It should be noted that those skilled in the art can make several improvements and modifications to this application without departing from the principles of this application, and these improvements and modifications also fall within the protection scope of the claims of this application.
