Description

Technical Field

[0001] This application relates to the field of automotive lighting technology, and in particular to a roof light and a vehicle using the roof light. Background Technology

[0002] Currently, there is an increasing number of cars with long wheelbases and large bodies, resulting in a significant increase in interior space. For these types of vehicles, the seats have a greater range of forward and backward movement, allowing passengers to flexibly adjust the seat position according to their needs.

[0003] However, in related technologies, the illumination area of ​​the overhead light is fixed. When the seat position changes significantly, the overhead light may not be able to accurately match the passenger's lighting needs, affecting the user experience. Utility Model Content

[0004] In view of this, embodiments of this application provide a roof light and a vehicle to solve the technical problem that the roof light is unable to meet the lighting needs of passengers when the seat position changes significantly.

[0005] In a first aspect, this application provides a roof light for mounting on the body of a vehicle, the roof light comprising: Lamp holder, used to fix it to the vehicle body; The lighting module is rotatably mounted on the lamp holder, and the lighting module has a light-emitting hole; A driving component is installed in the lamp holder and is drivingly connected to the lighting module. The driving component is used to drive the lighting module to rotate around a first axis to change the orientation of the light-emitting hole.

[0006] Thus, when the vehicle seat moves forward relative to the vehicle body, the user can drive the lighting module to rotate forward around the first axis via the drive component, thereby moving the light-emitting aperture towards the direction closer to the front of the vehicle, so that the illumination area of ​​the light-emitting aperture can move forward to cover the position where the vehicle seat is located; when the vehicle seat moves backward relative to the vehicle body, the user can drive the lighting module to rotate backward around the first axis via the drive component, thereby moving the light-emitting aperture towards the direction closer to the rear of the vehicle, so that the illumination area of ​​the light-emitting aperture can move backward to cover the position where the vehicle seat is located, thus ensuring that the roof light can still meet the lighting needs of passengers even when the position of the vehicle seat changes significantly.

[0007] As an optional implementation, when the lamp holder is installed on the vehicle body, a receiving cavity is formed between the lamp holder and the vehicle body, and the lamp holder has a through hole communicating with the receiving cavity; A portion of the lighting module is located within the receiving cavity, and the portion of the lighting module having the light-emitting hole extends out of the receiving cavity from the through hole.

[0008] In this way, a portion of the lighting module can be installed inside the receiving cavity, and the part of the lighting module with the light-emitting hole extends out of the receiving cavity from the through hole, so that the lamp holder can protect the lighting module and improve the utilization rate of the vehicle body space. Since the light-emitting hole is located outside the receiving cavity, when the lighting module is driven to rotate, it can prevent the lamp holder from blocking the light-emitting hole, thereby preventing the lamp holder from affecting the normal lighting of the lighting module.

[0009] As an optional implementation, the lighting module includes: Lamp housing, wherein the lamp housing has the light-emitting hole; A light panel, which is installed inside the lamp housing, and the light source on the light panel is positioned facing the light outlet hole; A transmission component is fixed to the lamp housing and connected to the output shaft of the drive component.

[0010] Thus, when the driving component drives the transmission component to rotate around the first axis, the transmission component can drive the lamp housing to rotate around the first axis, and the lamp panel can rotate synchronously with the lamp housing around the first axis, so that the light emitted by the light source can always be emitted outward from the light outlet hole, and the coverage area of ​​the light source can also be easily adjusted to meet the lighting needs of passengers.

[0011] As an optional implementation, the transmission component includes: The first part is embedded in the lamp housing; The second part is connected to the first part, and the second part is also connected to the output shaft of the transmission component.

[0012] Thus, when the drive unit is in operation, the power is transmitted from the second part to the first part. Since the second part and the lamp housing have been integrated through injection molding, the entire lamp housing is eventually driven to rotate around the first axis to meet the multi-angle lighting needs inside the vehicle.

[0013] As an optional implementation, the outer surface of the lamp housing is spherical.

[0014] In this way, the space occupied by the lamp housing when rotating around the first axis is minimized, which can reduce the space occupied by the roof light and also prevent the lamp housing from interfering with other components during rotation.

[0015] As an optional implementation, the lighting module further includes: The rear cover is fitted onto the side of the lamp housing facing away from the light emission hole. The rear cover is provided with a first limiting member and a second limiting member, which are respectively located on opposite sides of the first axis. When the driving member drives the lighting module to rotate in the positive direction around the first axis and moves the first limiting member to abut against the lamp holder, the light-emitting hole is located in the first position. When the driving member drives the lighting module to rotate in the opposite direction around the first axis and moves the second limiting member to abut against the lamp holder, the light-emitting hole is located in the second position.

[0016] Thus, when the driving component drives the lighting module to rotate forward around the first axis, the lamp housing drives the first limiting component to move closer to the lamp holder and drives the second limiting component to move away from the lamp holder. When the first limiting component abuts against the lamp holder, it can prevent the lighting module from continuing to rotate forward around the first axis. At this time, the light outlet is located in the first position, and the light emitted from the light outlet can cover the first area. The first area corresponds to the first extreme position of the vehicle seat when it is adjusted forward, which can meet the lighting needs when the vehicle seat is adjusted forward to the extreme position.

[0017] When the driving component drives the lighting module to rotate in the opposite direction around the first axis, the lamp housing drives the first limiting member to move away from the lamp holder and drives the second limiting member to move closer to the lamp holder. When the second limiting member abuts against the lamp holder, it can prevent the lighting module from continuing to rotate in the opposite direction around the first axis. At this time, the light outlet is located in the second position, and the light emitted from the light outlet can cover the second area. The second area corresponds to the second extreme position of the vehicle seat when it is adjusted backward, which can meet the lighting needs when the vehicle seat is adjusted backward to the extreme position.

[0018] By setting a first limiting member and a second limiting member on the rear cover, the movement of the light-emitting hole between the first and second positions can be restricted, preventing the light-emitting hole from moving to a position where it cannot provide lighting for passengers, thus better meeting the passengers' lighting needs. Furthermore, during the rotation of the lighting module, the light-emitting hole can be moved between the first and second positions, allowing the light emitted from the light-emitting hole to cover the space between the first and second areas, thereby meeting the multi-angle lighting needs within the vehicle body.

[0019] As an optional implementation, the lamp holder is provided with a first protrusion and a second protrusion, the first protrusion and the second protrusion being located on opposite sides of the first axis; When the light-emitting hole is located in the first position, the first limiting member abuts against the first protrusion. When the light-emitting hole is in the second position, the second limiting member abuts against the second protrusion.

[0020] Thus, by setting the first protrusion, the lamp holder can better form an abutment fit with the first limiting member to position the light emission hole at the first position, and the height of the first protrusion relative to the lamp holder can also change the first position of the light emission hole.

[0021] Similarly, by setting the second protrusion, the lamp holder can better form an abutment fit with the second limiting member to position the light emission hole in the second position, and the height of the second protrusion relative to the lamp holder can change the second position of the light emission hole.

[0022] As an optional implementation, the lamp housing is provided with a cylinder, and the cylinder and the driving member are arranged on opposite sides of the lamp housing along the extension direction of the first axis. The lighting module further includes: A protective plate is connected to the lamp holder, and a rotating groove is formed between the protective plate and the lamp holder. The cylinder is inserted into the rotating groove and can rotate around the first axis within the rotating groove.

[0023] In this way, one side of the lamp housing can be rotatably connected to the lamp holder, and the other side of the lamp housing can be driven to connect to the driving component. When the driving component drives the lamp housing to rotate around the first axis, the lamp housing can rotate more stably.

[0024] As an optional implementation, the centerline of the light-emitting aperture is perpendicular to the first axis.

[0025] In this way, the light emitted from the light outlet can cover the area along the sliding path of the vehicle seat to meet the multi-angle lighting needs inside the vehicle.

[0026] Secondly, this application also provides a vehicle, comprising: Body; A seat, which is slidably disposed on the vehicle body and is capable of sliding between a first limit position and a second limit position; The roof light described above is mounted on the vehicle body; The driving component drives the lighting module to rotate around the first axis, so that the light-emitting hole switches between a first position and a second position; When the light-emitting aperture is located at the first position, the illumination area of ​​the illumination module covers the first extreme position; When the light-emitting aperture is located in the second position, the illumination area of ​​the illumination module covers the second extreme position.

[0027] The vehicle provided in this application, by adopting the aforementioned headlights, can meet the lighting requirements when the seat is adjusted to the first and second extreme positions. Attached Figure Description

[0030] The technical solutions in this application will be clearly and thoroughly described below with reference to the accompanying drawings. In the description of the embodiments of this application, unless otherwise stated, " / " means "or," for example, A / B can mean A or B. "And / or" in the text is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Furthermore, in the description of the embodiments of this application, "multiple" refers to two or more than two.

[0031] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as implying or suggesting relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0032] Currently, when driving at night, due to insufficient light and reduced visibility, drivers need to use low beam or high beam headlights appropriately to illuminate the road ahead and ensure driving safety. At the same time, the interior space of the vehicle also requires lighting support, usually by installing dome lights on the roof to meet basic lighting needs. These dome lights are mostly fixed in design, with a relatively concentrated light coverage area, providing basic ambient lighting for passengers.

[0033] With the increasing popularity of long-wheelbase, large-body vehicles, interior space has significantly expanded, and the adjustability of seats has also increased accordingly. Modern car seats generally support functions such as fore-and-aft sliding and backrest angle adjustment, allowing passengers to flexibly adjust the seat position according to their actual needs.

[0034] However, since the area illuminated by the overhead light is fixed, when the seat position is significantly adjusted (for example, the front passenger moves the seat back significantly, or the rear passenger moves the seat forward to increase legroom), the light from the overhead light may not accurately cover the area where the passenger is located, resulting in insufficient lighting in scenarios such as reading and operating devices, thus affecting the user experience.

[0035] Based on this, this application provides a vehicle roof light 100 and a vehicle, wherein the lamp holder 10 is fixed to the vehicle body, the lighting module 20 is rotatably mounted on the lamp holder 10, and the lighting module 20 has a light emission hole 210. The driving member 30 is drivenly connected to the lighting module 20. When the seat position is adjusted significantly, the user can drive the lighting module 20 to rotate around the first axis Z through the driving member 30 to change the orientation of the light emission hole 210, so that the lighting area of ​​the lighting module 20 can cover the seat location to meet the passenger's lighting needs.

[0036] The embodiments of this application will be described in detail below with reference to the accompanying drawings and specific implementation details.

[0037] Please see Figure 1 and Figure 2 This application provides a vehicle roof light 100, which is used to install on the body of a vehicle. The vehicle roof light 100 includes a lamp holder 10, a lighting module 20, and a driver 30. The lamp holder 10 is fixed to the vehicle body. The lighting module 20 is rotatably disposed on the lamp holder 10 and has a light emission hole 210. The driver 30 is installed on the lamp holder 10 and is drivenly connected to the lighting module 20. The driver 30 is used to drive the lighting module 20 to rotate around a first axis Z to change the orientation of the light emission hole 210.

[0038] Optionally, the lamp holder 10 can be installed on the top of the vehicle body, and the lamp holder 10 is located above the vehicle seat. The lighting module 20 is rotatably mounted on the lamp holder 10, and the light emission hole 210 of the lighting module 20 is set downward, that is, the light emission hole 210 is set towards the direction where the seat is located. The driving component 30 can be a stepper motor, and the output shaft of the driving component 30 is connected to the lighting module 20. The driving component 30 drives the lighting module 20 to rotate around the first axis Z. The extension direction of the first axis Z can be the same as the direction in which the vehicle seat slides relative to the vehicle body.

[0039] Thus, when the vehicle seat moves forward relative to the vehicle body, the user can drive the lighting module 20 to rotate forward around the first axis Z via the drive component 30, thereby causing the light-emitting hole 210 to move towards the direction closer to the front of the vehicle, so that the lighting area of ​​the light-emitting hole 210 can move forward to cover the position where the vehicle seat is located; when the vehicle seat moves backward relative to the vehicle body, the user can drive the lighting module 20 to rotate backward around the first axis Z via the drive component 30, thereby causing the light-emitting hole 210 to move towards the direction closer to the rear of the vehicle, so that the lighting area of ​​the light-emitting hole 210 can move backward to cover the position where the vehicle seat is located, thus ensuring that the roof light 100 can still meet the lighting needs of passengers even when the position of the vehicle seat changes significantly.

[0040] Please see Figures 1 to 3 In some embodiments, when the lamp holder 10 is installed on the vehicle body, a receiving cavity is formed between the lamp holder 10 and the vehicle body. The lamp holder 10 has a through hole 101 communicating with the receiving cavity. A portion of the lighting module 20 is located inside the receiving cavity, and a portion of the lighting module 20 having a light emission hole 210 extends out of the receiving cavity from the through hole 101.

[0041] In this embodiment, the lamp holder 10 includes a base and four fixing feet. The base has a through hole 101 that penetrates the opposite sides of the base. The four fixing feet are all located on the same side of the base and are located at the four corners of the base. The four fixing feet extend away from the base and can be connected to the vehicle body, so that a receiving cavity can be formed between the base and the vehicle body.

[0042] Thus, a portion of the lighting module 20 can be fitted into the receiving cavity, and the portion of the lighting module 20 with the light emission hole 210 extends out of the receiving cavity from the through hole 101, so that the lamp holder 10 can protect the lighting module 20 and improve the utilization rate of the vehicle interior space. Since the light emission hole 210 is located outside the receiving cavity, when the lighting module 20 is driven to rotate, the lamp holder 10 can be prevented from blocking the light emission hole 210, thereby preventing the lamp holder 10 from affecting the normal illumination of the lighting module 20.

[0043] When installing the roof light 100, the lighting module 20 can be rotated and installed on the lamp holder 10. The main body of the lighting module 20 is located between the four fixed feet. The part of the lighting module 20 with the light emission hole 210 extends out from the through hole 101, and the light emission hole 210 is located on the side of the base body facing away from the four fixed feet. Then, the four fixed feet are fastened to the vehicle body. For example, bolts are used to pass through the connecting holes on the fixed feet and the bolts are locked with the pre-set threaded holes or nuts on the vehicle body, so that the fixed feet are fixed to the vehicle body and a receiving cavity can be formed between the base body and the vehicle body. In this way, the main body of the lighting module 20 is assembled in the receiving cavity, and the part of the lighting module 20 with the light emission hole 210 extends out from the through hole 101 to the outside of the receiving cavity, ensuring that the lamp holder 10 does not block the light emitted by the lighting module 20.

[0044] In some embodiments, the lamp holder 10 further includes a mounting bracket connected to the base body, and the mounting member and the fixing foot are located on the same side of the base body. The drive member 30 is fixed on the mounting bracket, and the output shaft of the drive member 30 is drivenly connected to the lighting module 20.

[0045] Please see Figures 3 to 5 In some embodiments, the lighting module 20 includes a lamp housing 21, a lamp plate 22, and a transmission component 23. The lamp housing 21 has a light-emitting hole 210. The lamp plate 22 is installed inside the lamp housing 21, and the light source on the lamp plate 22 is arranged facing the light-emitting hole 210. The transmission component 23 is fixed to the lamp housing 21, and the transmission component 23 is connected to the output shaft of the drive component 30.

[0046] Optionally, the lamp housing 21 has a support column inside, the lamp plate 22 is fixed on the support column, and the light source on the lamp plate 22 is set in the direction of the light outlet hole 210. The light emitted by the light source can be emitted outward from the light outlet hole 210. One end of the transmission member 23 can be fixed to the lamp housing 21, and the other end of the transmission member 23 can be connected to the output shaft of the drive member 30.

[0047] Thus, when the driving component 30 drives the transmission component 23 to rotate around the first axis Z, the transmission component 23 can drive the lamp housing 21 to rotate around the first axis Z, and the lamp plate 22 can rotate synchronously with the lamp housing 21 around the first axis Z, so that the light emitted by the light source can always be emitted outward from the light outlet 210, and the coverage area of ​​the light source can also be easily adjusted to meet the lighting needs of passengers.

[0048] Please see Figure 3 , Figure 5 and Figure 6 In some embodiments, the transmission component 23 includes a first part 231 and a second part 232. The first part 231 is embedded in the lamp housing 21, the second part 232 is connected to the first part 231, and the second part 232 is also connected to the output shaft of the drive component 30.

[0049] In this embodiment, the first part 231 serves as a support structure that drives the lamp housing 21 to rotate. The first part 231 can be a ring-shaped metal insert. The second part 232 serves as a power transmission component. The second part 232 can be a metal connecting rod. One end of the second part 232 is provided with a standard interface that can be directly assembled with the output shaft of the drive component 30.

[0050] The lamp housing 21 is made of plastic and is formed by injection molding. During the injection molding process, the first part 231 is pre-placed in the mold cavity so that the plastic melt completely covers the outer periphery of the first part 231 to form an embedded structure. After cooling and solidification, the first part 231 is embedded in the formed lamp housing 21.

[0051] When assembling the roof light 100, the second part 232 is rigidly connected to the output shaft of the drive component 30 through a spline or D-hole. When the drive component 30 is running, the power is transmitted to the first part 231 through the second part 232. Since the second part 232 and the lamp housing 21 have been solidified into one piece through injection molding, the entire lamp housing 21 is eventually driven to rotate around the first axis Z to meet the multi-angle lighting needs inside the vehicle.

[0052] Please see Figure 5 In some embodiments, the outer surface of the lamp housing 21 is spherical.

[0053] It is understandable that the lamp housing 21 is a component that forms the outer contour shape of the lighting module 20. When the outer surface of the lamp housing 21 is spherical, the space occupied by the lamp housing 21 when rotating around the first axis Z is minimized, which can reduce the space occupied by the roof light 100 and also prevent the lamp housing 21 from interfering with other components during rotation.

[0054] Please see Figure 1 and Figure 2 In some embodiments, the lighting module 20 further includes a rear cover 24, which covers the side of the lamp housing 21 facing away from the light emission hole 210. The rear cover 24 is provided with a first limiting member 241 and a second limiting member 242, which are respectively located on opposite sides of the first axis Z. When the driving member 30 drives the lighting module 20 to rotate in the forward direction around the first axis Z and moves the first limiting member 241 to abut against the lamp holder 10, the light emission hole 210 is located in the first position. When the driving member 30 drives the lighting module 20 to rotate in the reverse direction around the first axis Z and moves the second limiting member 242 to abut against the lamp holder 10, the light emission hole 210 is located in the second position.

[0055] Optionally, the back cover 24 and the lamp housing 21 are closed together to prevent foreign objects from entering the lamp housing 21. The first limiting member 241 and the second limiting member 242 are both located on the outer periphery of the back cover 24, and the first limiting member 241 and the second limiting member 242 are respectively located on opposite sides of the first axis Z. The extending direction of the first limiting member 241 is opposite to the extending direction of the second limiting member 242.

[0056] Thus, when the driving member 30 drives the lighting module 20 to rotate positively around the first axis Z, the lamp housing 21 drives the first limiting member 241 to move closer to the lamp holder 10 and drives the second limiting member 242 to move away from the lamp holder 10. When the first limiting member 241 abuts against the lamp holder 10, it can prevent the lighting module 20 from continuing to rotate positively around the first axis Z. At this time, the light outlet 210 is located in the first position, and the light emitted from the light outlet 210 can cover the first area. The first area corresponds to the first extreme position of the vehicle seat when it is adjusted forward, which can meet the lighting needs when the vehicle seat is adjusted forward to the extreme position.

[0057] When the driving member 30 drives the lighting module 20 to rotate in the opposite direction around the first axis Z, the lamp housing 21 drives the first limiting member 241 to move away from the lamp holder 10 and drives the second limiting member 242 to move closer to the lamp holder 10. When the second limiting member 242 abuts against the lamp holder 10, it can prevent the lighting module 20 from continuing to rotate in the opposite direction around the first axis Z. At this time, the light outlet 210 is located in the second position, and the light emitted from the light outlet 210 can cover the second area. The second area corresponds to the second extreme position of the vehicle seat when it is adjusted backward, which can meet the lighting needs when the vehicle seat is adjusted backward to the extreme position.

[0058] By providing a first limiting member 241 and a second limiting member 242 on the rear cover 24, the movement of the light-emitting hole 210 between the first and second positions can be restricted, preventing the light-emitting hole 210 from moving to a position where it cannot provide illumination for passengers, thus better meeting the passengers' lighting needs. Furthermore, during rotation, the lighting module 20 can move the light-emitting hole 210 between the first and second positions, allowing the light emitted from the light-emitting hole 210 to cover the space between the first and second areas, thereby meeting the multi-angle lighting needs within the vehicle body.

[0059] In some other embodiments, the rear cover 24 is also provided with a plurality of heat dissipation holes, all of which are arranged facing the lamp panel 22. The plurality of heat dissipation holes can increase the airflow between the lamp housing 21 and the outside air, and the heat generated by the lamp panel 22 can be transferred to the outside air through the airflow, thereby improving the heat dissipation efficiency of the roof light 100.

[0060] Please see Figure 1 and Figure 2In some embodiments, the lamp holder 10 is provided with a first protrusion 11 and a second protrusion 12, which are located on opposite sides of the first axis Z. When the light-emitting hole 210 is in the first position, the first limiting member 241 abuts against the first protrusion 11, and when the light-emitting hole 210 is in the second position, the second limiting member 242 abuts against the second protrusion 12.

[0061] In this embodiment, the first protrusion 11 and the second protrusion 12 are located on the same side of the lamp holder 10, and both the first protrusion 11 and the second protrusion 12 protrude in a direction away from the lamp holder 10. The first protrusion 11 and the second protrusion 12 are located on opposite sides of the first axis Z. The first protrusion 11 is correspondingly provided with the first limiting member 241, and the second protrusion 12 is correspondingly provided with the second limiting member 242.

[0062] When the driving member 30 drives the lighting module 20 to rotate forward about the first axis Z and the light outlet 210 is in the first position, the first limiting member 241 can abut against the first protrusion 11 to prevent the lighting module 20 from continuing to rotate forward; when the driving member 30 drives the lighting module 20 to rotate backward about the first axis Z and the light outlet 210 is in the second position, the second limiting member 242 can abut against the second protrusion 12 to prevent the lighting module 20 from continuing to rotate backward.

[0063] Thus, by setting the first protrusion 11, the lamp holder 10 can better form an abutment with the first limiting member 241 to position the light emission hole 210 in the first position, and the height of the first protrusion 11 relative to the lamp holder 10 can also change the first position of the light emission hole 210.

[0064] Similarly, by setting the second protrusion 12, the lamp holder 10 can better form an abutment with the second limiting member 242 to position the light emission hole 210 in the second position, and the height of the second protrusion 12 relative to the lamp holder 10 can change the second position of the light emission hole 210.

[0065] Please see Figure 3 , Figure 5 and Figure 7 In some embodiments, the lamp housing 21 is provided with a cylinder 211, and the cylinder 211 and the driving member 30 are arranged on opposite sides of the lamp housing 21 along the extension direction of the first axis Z. The lighting module 20 also includes a protective plate 25, which is connected to the lamp holder 10. A rotating groove 102 is formed between the protective plate 25 and the lamp holder 10. The cylinder 211 is inserted into the rotating groove 102 and can rotate around the first axis Z in the rotating groove 102.

[0066] Optionally, the lamp housing 21 has a cylinder 211 on the side facing away from the drive member 30. The cylinder 211 extends away from the drive member 30, and the axis of the cylinder 211 coincides with the first axis Z. The lamp holder 10 has a first groove that communicates with the through hole 101. The groove wall of the first groove includes a first arc surface that extends around the first axis Z. The guard plate 25 has a second groove. When the guard plate 25 is installed on the lamp housing 21, the second groove and the first groove together form a rotating groove 102 that communicates with the through hole 101. The groove wall of the second groove includes a second arc surface that extends around the first axis Z. When the cylinder 211 is inserted into the rotating groove 102, the cylinder 211 can cooperate with the first arc surface and the second arc surface, so that the cylinder 211 can rotate around the first axis Z in the rotating groove 102, thereby allowing the lamp housing 21 to be rotatably installed on the lamp holder 10.

[0067] In this way, one side of the lamp housing 21 can be rotatably connected to the lamp holder 10, and the other side of the lamp housing 21 can be driven to connect to the drive member 30. When the drive member 30 drives the lamp housing 21 to rotate around the first axis Z, the lamp housing 21 can rotate more stably.

[0068] In some embodiments, a turntable is provided at the end of the cylinder 211 away from the lamp housing 21. The diameter of the turntable is larger than the diameter of the cylinder 211. A first arc surface is provided with a first limiting groove, which communicates with a first recess. A second arc surface is provided with a second limiting groove, which communicates with a second recess. When the protective plate 25 is installed on the lamp housing 21, the first limiting groove and the second limiting groove can be closed to form a limiting groove. The limiting groove communicates with the rotating groove 102. The limiting groove extends around the first axis Z for one revolution, and the turntable is inserted into the limiting groove. The turntable can rotate around the first axis Z in the limiting groove, and the turntable and the limiting groove are matched to prevent the cylinder 211 from disengaging from the rotating groove 102, so that the lamp housing 21 can rotate more stably.

[0069] Please see Figure 3 In some embodiments, the axis of the light-emitting aperture 210 is perpendicular to the first axis Z.

[0070] In this embodiment, the vehicle seat can slide linearly along the front-rear direction of the vehicle body to adjust the front-rear position of the vehicle seat. The extension direction of the first axis Z is parallel to the left-right direction of the vehicle body. When the lamp housing 21 rotates around the first axis Z, the lamp housing 21 drives the light-emitting hole 210 to swing. The movement path of the light-emitting hole 210 is the first path, and the projection of the first path on the horizontal plane is the first straight line. The extension direction of the first straight line is parallel to the front-rear direction of the vehicle body. Thus, the movement path of the light-emitting hole 210 matches the sliding path of the vehicle seat, so that the light emitted from the light-emitting hole 210 can cover the area on the sliding path of the vehicle seat to meet the multi-angle lighting needs inside the vehicle body.

[0071] This embodiment also provides a vehicle, including a body, a seat, and the aforementioned roof light 100. The roof light 100 is mounted on the body, the seat is slidably disposed on the body, and the seat is slidable between a first extreme position and a second extreme position. The driving member 30 drives the lighting module 20 to rotate around a first axis Z, so that the light-emitting hole 210 switches between a first position and a second position. When the light-emitting hole 210 is in the first position, the lighting area of ​​the lighting module 20 covers the first extreme position, and when the light-emitting hole 210 is in the second position, the lighting area of ​​the lighting module 20 covers the second extreme position.

[0072] It should be noted that the vehicle provided in this embodiment should also include other modules or components that enable the vehicle to operate normally. Here, these other modules or components will not be described one by one.

[0073] The vehicle provided in this embodiment, by adopting the aforementioned roof light 100, can meet the lighting requirements when the seat is adjusted to the first and second extreme positions.

[0074] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
