Description

Technical Field

[0001] This application relates to the field of vehicle technology, and in particular to a vehicle-mounted multi-degree-of-freedom support, vehicle-mounted lighting components, system, and vehicle. Background Technology

[0002] With the continuous development of automotive technology and the increasing number of cars per capita, while improving transportation convenience, the number of traffic accidents has also increased significantly. The probability of a secondary accident following a primary accident is as high as 34%, and the fatality rate of a secondary accident is more than three times that of a primary accident. One of the main reasons for the high rate of secondary accidents is the inadequate post-accident evacuation protection system. Methods such as placing warning triangles, hazard lights, and wearing reflective vests are often insufficient, and even placing warning triangles carries significant risks (especially at high speeds and at night). Therefore, there is an urgent need to develop a vehicle-mounted, multi-degree-of-freedom, automatically rotating structure that can accurately warn following vehicles upon the discovery of an accident, reducing the probability of secondary accidents and ensuring the safety of evacuees from the scene. Summary of the Invention

[0003] The purpose of this application is to provide a vehicle-mounted multi-degree-of-freedom support, a vehicle-mounted lighting assembly, a system, and a vehicle, for realizing multi-degree-of-freedom movement of the supported component. When the supported component is a warning device, it can drive the warning device to accurately warn vehicles behind when an accident is detected.

[0004] To achieve the above objectives, this application adopts the following technical solution: In a first aspect, this application provides a vehicle-mounted multi-degree-of-freedom support. The vehicle-mounted multi-degree-of-freedom support includes: a cover, a first drive assembly, and a movable seat. The cover has a connecting portion that connects the inner side and the outer side of the cover, and the connecting portion is configured as an elongated groove along a direction parallel to the cover. The first drive assembly is disposed on the inner side of the cover. The movable seat is disposed on the outer side of the cover, and the movable seat includes a first connector that extends through the connecting portion into the inner side of the cover and connects to the first drive assembly. The first drive assembly is used to drive the movable seat to rotate and / or swing along the elongated groove.

[0005] In the vehicle-mounted multi-degree-of-freedom support of this application, the connecting portion of the cover can be understood as a through hole extending from the outside to the inside of the cover. This through hole is transversely constructed into a long strip shape, that is, the cross-section of the hole perpendicular to the through-hole direction is long. Thus, a long strip-shaped groove can be constructed in the direction parallel to the cover. With this design, after the first connecting member of the movable seat extends through the connecting portion into the inside of the cover, that is, after passing through the long strip-shaped groove, the first connecting member of the movable seat can rotate within the connecting portion and swing along the length of the long strip-shaped groove constructed by the connecting portion, thus realizing the two-degree-of-freedom changes of the movable seat.

[0006] The first drive assembly is connected to the first connector inside the cover, thereby enabling the first connector and the movable seat to move freely in two directions, achieving automatic control of the movable seat. The first drive assembly is located inside the cover, allowing for a concealed or semi-concealed design, which helps protect it from damage caused by external dust and other environmental factors, and also improves the overall neatness of the appearance.

[0007] The cover can be installed in different locations on the vehicle according to actual usage needs. For example, when the movable seat needs to automatically adjust the position of devices inside the vehicle (such as displays, seats, and other supported components), the cover can be installed inside the vehicle. Alternatively, when the movable seat needs to drive devices outside the vehicle, such as warning devices, light indicators, graphic indicators, or supported components like lights and projectors, the cover can be installed on the outer side of the vehicle's roof. In this case, the movable seat can be located on the side of the cover facing away from the roof. Controlling the movable seat's rotation and swinging along a long, narrow groove via a first drive component allows the device connected to the movable seat outside the vehicle to accurately face the target position. For example, in the event of an accident, it can drive the warning device to accurately warn vehicles behind, making it highly practical.

[0008] When the external warning device of a vehicle is a traffic light, the high warning effect of the light can be used to convey the signal that the vehicle and road users want to release, helping to improve the safety of evacuation in the event of an accident. Compared with the fact that general vehicle lights are fixed and difficult to transmit effective information over long distances, and that effective traffic lights such as general marker lights are fixed to the ground and difficult to quickly help people in the vehicle to complete signal transmission in the event of a traffic accident, the vehicle-mounted multi-degree-of-freedom support provided in this application can realize vehicle-mounted and multi-degree-of-freedom automatic rotation, thereby preventing the problem that the traffic light cannot face forward due to vehicle tilting, effectively reducing the probability of secondary accidents and protecting the safety of people evacuating from the scene of an accident.

[0009] In one possible implementation of the first aspect, the first drive assembly includes: a first bevel gear, a second bevel gear, a third bevel gear, a first motor, and a second motor. The first and second bevel gears are arranged in a mirror-symmetrical manner. The third bevel gear is located between the first and second bevel gears and meshes with both gears; the third bevel gear is also fixed to a first connecting member. The first motor drives the first bevel gear to rotate, and the second motor drives the second bevel gear to rotate.

[0010] In the above embodiments, the first bevel gear and the third bevel gear form an orthogonal transmission pair, and the second bevel gear and the third bevel gear form an orthogonal transmission pair. When the first motor and the second motor drive the first bevel gear and the second bevel gear at the same speed and in the same direction, the third bevel gear rotates around the axis of the first bevel gear and the second bevel gear, thereby driving the first connecting member and the movable seat to swing along the length of the elongated slide. When the first motor and the second motor drive the first bevel gear and the second bevel gear at the same speed and in opposite directions, the third bevel gear rotates around its own axis, thereby driving the first connecting member and the movable seat to rotate. When the first motor and the second motor drive the first bevel gear and the second bevel gear at different speeds and in opposite directions, the third bevel gear rotates around its own axis and also rotates around the axis of the first bevel gear and the second bevel gear, thereby driving the first connecting member and the movable seat to rotate and swing along the length of the elongated slide, achieving compound motion. In practical applications, the two motors can be used to control the movable seat to move in a suitable manner according to the specific application requirements of the scenario, so as to quickly move to the target position.

[0011] In one possible implementation of the first aspect, the first motor and the second motor are arranged opposite to each other and fixed, and the first bevel gear and the second bevel gear are located between the first motor and the second motor.

[0012] In the above embodiment, the first motor, the second motor, the first bevel gear, and the second bevel gear are arranged in a linear layout, which helps to reduce the size along the radial direction of the motor and makes the layout more compact. When arranged on the roof of the vehicle, the axis of the motor can correspond to the left and right direction of the vehicle. In this way, the space occupied in the front and rear directions of the roof will be very small, without affecting the arrangement of other structures (such as sunroof).

[0013] In one possible implementation of the first aspect, the first drive assembly further includes: a first reduction mechanism and a second reduction mechanism. The first reduction mechanism is disposed between the output end of the first motor and the first bevel gear. The second reduction mechanism is disposed between the output end of the second motor and the second bevel gear.

[0014] In the above embodiments, the first reduction mechanism can convert the kinetic energy output by the first motor from high speed and low torque to low speed and high torque, thereby enabling smoother control of the rotation of the first bevel gear. The second reduction mechanism can convert the kinetic energy output by the second motor from high speed and low torque to low speed and high torque, thereby enabling smoother control of the rotation of the second bevel gear. With this design, when the first and second bevel gears drive the third bevel gear simultaneously, the movement is more stable and reliable, and problems such as slippage and tooth breakage are less likely to occur.

[0015] In one possible embodiment of the first aspect, the first bevel gear includes: a plurality of first teeth, a first limiting portion, and a second limiting portion. The plurality of first teeth are arranged circumferentially around the first bevel gear and are used to mesh with a third bevel gear; the first limiting portion is disposed on one side of the plurality of first teeth along the circumferential direction of the first bevel gear; and the second limiting portion is disposed on the other side of the plurality of first teeth along the circumferential direction of the first bevel gear. The second bevel gear includes: a plurality of second teeth, a third limiting portion, and a fourth limiting portion. The plurality of second teeth are arranged circumferentially around the second bevel gear and are used to mesh with a third bevel gear; the third limiting portion is disposed on one side of the plurality of second teeth along the circumferential direction of the second bevel gear; and the fourth limiting portion is disposed on the other side of the plurality of second teeth along the circumferential direction of the second bevel gear.

[0016] In the above embodiment, the first and second limiting portions limit both ends of the plurality of first teeth arranged circumferentially on the first bevel gear. When the plurality of first teeth of the first bevel gear mesh with the third bevel gear, engagement at the first limiting portion restricts further engagement in a direction away from the first teeth, and engagement at the second limiting portion restricts further engagement in a direction away from the first teeth. Similarly, the third and fourth limiting portions limit both ends of the plurality of second teeth arranged circumferentially on the second bevel gear. When the plurality of second teeth of the second bevel gear mesh with the third bevel gear, engagement at the third limiting portion restricts further engagement in a direction away from the second teeth, and engagement at the fourth limiting portion restricts further engagement in a direction away from the first teeth. The above solution can prevent the third bevel gear from rotating excessively and / or swinging excessively along the length of the long strip groove, thereby preventing the movable seat connected to the third bevel gear and the device (such as a lamp) subsequently installed on the movable seat from rotating excessively and / or swinging excessively, so as to improve the collision risk caused by excessive rotation. For example, when the roof lamp is rotating, it is not easy to collide with the vehicle roof or glass due to excessive rotation.

[0017] There are no restrictions on the size and number of multiple first teeth or multiple second teeth here. They can be determined later based on the design rotation and swing angles and transmission accuracy of the device actually installed on the movable seat, which are not likely to interfere with the surrounding structure.

[0018] In one possible implementation of the first aspect, the third bevel gear includes: a plurality of third teeth, a fifth limiting portion, and a sixth limiting portion. The plurality of third teeth are arranged circumferentially along the third bevel gear and are used to mesh with the first bevel gear and the second bevel gear; the fifth limiting portion is disposed on one side of the plurality of third teeth along the circumferential direction of the third bevel gear; and the sixth limiting portion is disposed on the other side of the plurality of third teeth along the circumferential direction of the third bevel gear.

[0019] In the above embodiment, the fifth and sixth limiting portions limit both ends of the plurality of third teeth circumferentially arranged on the third bevel gear. This prevents the multiple third teeth of the third bevel gear from simultaneously meshing with the first and second bevel gears. At the fifth limiting portion, the engagement is restricted from continuing in a direction away from the third teeth, and at the sixth limiting portion, it is also restricted from continuing in a direction away from the third teeth. This solution further prevents excessive rotation of the third bevel gear, thereby preventing excessive rotation of the movable seat connected to the third bevel gear and subsequent devices (such as lamps) mounted on the movable seat. This reduces the risk of collisions caused by excessive rotation; for example, when a roof lamp rotates, it is less likely to collide with the vehicle roof or glass due to excessive rotation.

[0020] There are no restrictions on the size and number of the multiple third teeth here. They can be determined later based on the design of the rotation and swing angles and transmission accuracy of the device actually installed on the movable seat, which are not likely to interfere with the surrounding structure.

[0021] In one possible implementation of the first aspect, the vehicle-mounted multi-degree-of-freedom support further includes: a fixed base, a telescopic frame, and a second drive assembly. The fixed base is used to connect to the vehicle. The telescopic frame is disposed between the fixed base and the cover. The second drive assembly is disposed on the fixed base and connects to the telescopic frame and / or the cover for driving the cover to rise and fall relative to the fixed base.

[0022] In the above embodiment, the fixed base can be fixed to the vehicle, providing stable support. The telescopic frame between the cover and the fixed base allows the cover to be raised or lowered relative to the fixed base. The second drive assembly enables the automatic raising and lowering function of the cover. When the telescopic frame is in the retracted state, the cover can be fastened to the fixed base, forming a flat structure with reduced space occupation. When the telescopic frame is in the extended state, the cover moves away from the fixed base, which is equivalent to raising the cover to a certain height. This allows the connected devices above the movable base to be raised to a higher position, such as raising the interior seats, display screens, etc., and raising the exterior traffic lights to make them more visible to surrounding people.

[0023] In one possible implementation of the first aspect, the telescopic frame includes: at least two cross-shaped linkage groups, spaced apart along a direction parallel to the cover; wherein the cross-shaped linkage group includes a first link and a second link arranged crosswise, the first link and the second link are hinged at the cross position, the first end of the first link and the first end of the second link are rotatably connected to different positions of the fixed seat, and the second end of the first link and the second end of the second link are rotatably connected to different positions of the cover.

[0024] In the above embodiment, the cross-shaped linkage assembly has a simple structure and is easy to store. On the one hand, it can effectively support the cover when unfolded, and on the other hand, it can reduce space occupation when retracted. Here, at least two cross-shaped linkage assemblies arranged at intervals along a direction parallel to the cover can play a role in stabilizing and supporting the cover. The structure is simple and the connection is reliable.

[0025] In one possible implementation of the first aspect, the second drive assembly includes a cooperating hydraulic cylinder and a hydraulic push rod, the hydraulic cylinder being disposed on a fixed base, one end of the hydraulic push rod extending into the hydraulic cylinder, and the other end being hinged to the telescopic frame or fixedly connected to the cover.

[0026] In the above embodiments, under the action of hydraulic pressure, the exposed end of the hydraulic push rod can be pushed to extend and retract further, thereby driving the telescopic frame to move the cover, or directly driving the cover to move. Since the angle of the connecting rod in the telescopic frame changes, the hydraulic push rod can be connected to the connecting rod using a hinged connection. However, when connected to the cover, it can be directly fixed along the lifting direction, without involving angle changes.

[0027] In another possible implementation of the first aspect, the second drive assembly includes a motor and a transmission mechanism such as gears and / or hinges. The hydraulic cylinder and hydraulic push rod can be replaced by the transmission mechanism such as the motor and gears and / or hinges to drive the cover to rise and fall. This design has the advantage of occupying little space, which is conducive to achieving a compact space miniaturized layout, thereby reducing the overall structural size.

[0028] In one possible implementation of the first aspect, the vehicle-mounted multi-degree-of-freedom support further includes: a buffer structure disposed on the side of the cover facing the fixed seat, and / or disposed on the side of the fixed seat facing the cover.

[0029] In the above embodiments, the buffer structure can be made of materials such as foam that have stress-absorbing and sound-dampening effects. This makes it less prone to frictional wear when the cover and the fixing seat are in contact, and also reduces the generation of abnormal noise, thus improving the comfort of using the product.

[0030] In one possible implementation of the first aspect, the buffer structure includes: a first buffer member and a second buffer member, disposed on both sides of the cover and / or both sides of the fixing seat in a direction parallel to the cover body.

[0031] In the above embodiments, the first and second buffer components can effectively buffer and muffle noise.

[0032] In one possible implementation of the first aspect, the cover includes a retaining edge around its perimeter, the retaining edge protruding toward the mounting base.

[0033] In the above embodiment, the protruding edges around the cover facing the fixed base can hide and protect the first drive assembly and telescopic frame inside the cover, and the overall appearance can be neater.

[0034] In one possible implementation, when the cover is fastened to the fixed seat, the flange along the direction of movement of the cover can abut against the fixed seat, thereby forming a certain height space between the cover and the fixed seat to accommodate and protect structures such as the first drive assembly.

[0035] In another possible implementation, when the cover and the fixing seat are fastened together, the retaining edge can protect the surrounding area of ​​the fixing seat, thereby enclosing the fixing seat inside the cover, resulting in better overall structure and higher integration.

[0036] In one possible implementation of the first aspect, the movable seat further includes a second connector that protrudes toward the side of the movable seat opposite to the first connector.

[0037] In the above embodiment, the second connector protruding from the side of the movable seat opposite to the first connector can be raised, so that the device structure connected to the second connector can be set at a higher position.

[0038] Secondly, a vehicle-mounted lighting assembly is provided. The vehicle-mounted lighting assembly includes: a vehicle-mounted multi-degree-of-freedom support according to any embodiment of the first aspect; and a lighting fixture connected to a movable seat of the vehicle-mounted multi-degree-of-freedom support.

[0039] In the vehicle lighting assembly of this application, the function and role of the vehicle-mounted multi-degree-of-freedom support base are as described above. It can automatically control the rotation of the movable base and / or its swing along the elongated slide. The lighting fixture can be connected to the movable base, for example, to a second connecting member on the movable base, thereby increasing the installation height and improving the lighting fixture's radiation range. The connection between the lighting fixture and the vehicle-mounted multi-degree-of-freedom support base allows the lighting fixture to rotate to adjust its orientation and to swing along the direction corresponding to the elongated slide to adjust its pitch angle. This facilitates more accurate alignment of the lighting fixture with the target position, for example, preventing the signal lights from not facing backwards due to vehicle tilt, effectively reducing the probability of secondary accidents and protecting the safety of personnel evacuating from the accident scene.

[0040] In one possible implementation of the second aspect, the luminaire is used to provide one or more of illumination, projection, ambiance design, and prompting information; the prompting information includes one or more of text prompting information, graphic prompting information, and strobe prompting information.

[0041] In the above embodiments, illumination refers to emitting ordinary light beams, such as white or colored beams, for example, illuminating the gathering area in a camping party scene, or providing footlight illumination for pedestrians. Projection refers to emitting projection beams, such as projecting images or text information; the projected information can be static or dynamic. Atmosphere design can be customized by combining specific locations and patterns to create a lighting atmosphere. Lighting fixtures used to display prompts refer to the ability to send alerts to the outside world, such as by directly displaying illuminated text, illuminated images, or flashing information at specific frequencies to issue warnings, distress signals, etc. Through the above solutions, the intelligent interaction function between the vehicle and the outside world can be enhanced.

[0042] In one possible implementation of the second aspect, when the first connector is in the first position of the elongated groove, the luminous surface of the lamp is perpendicular to the cover; when the first connector is in the second position of the elongated groove, the luminous surface of the lamp forms an acute or obtuse angle with the cover.

[0043] In the above embodiments, when the first connector is moved to different positions in the elongated slide, the lamp set on the movable seat will move to the corresponding different positions. For example, when the first connector is in the first position, the light-emitting surface of the lamp is perpendicular to the cover, while when the first connector is in the second position, the light-emitting surface of the lamp can form an acute angle or an obtuse angle with the cover. That is, by changing the position of the first connector in the elongated slide, the angle between the light-emitting surface of the lamp and the cover can be adjusted, so as to control the light-emitting surface of the lamp to face the required position height and achieve more precise light control.

[0044] In one possible implementation of the second aspect, the luminaire includes a rear housing, a lampshade, and a lamp panel assembly. The rear housing and the lampshade are interlocked to form a receiving space. The lamp panel assembly is disposed within the receiving space.

[0045] In the above embodiment, the rear shell can be connected to the second connector of the movable base, thereby fixing the lamp to the movable base. The receiving space formed by the rear shell and the lamp cover can accommodate the lamp board assembly, thus protecting the lamp board assembly. The light emitted by the lamp board assembly can be projected to the outside of the lamp cover through the lamp cover. The lamp board assembly may include a circuit board and multiple LED beads located on the circuit board.

[0046] In one possible implementation, the lampshade may include a pre-set textured structure that can be used to generate uniform light, improve the uniformity of light output, and prevent glaring bright spots from being generated through the lampshade.

[0047] In one possible implementation of the second aspect, the luminaire further includes a heat dissipation assembly disposed on the outside of the rear housing.

[0048] In the above embodiment, the heat dissipation component connected to the rear shell can dissipate heat to the external environment when the lamp panel assembly is continuously operating and generating heat, reducing the risk of thermal damage to the lamp panel assembly. The heat dissipation component can use methods such as air cooling or water cooling for heat dissipation.

[0049] In one possible implementation of the second aspect, the luminaire further includes: a light-shielding ring and a plurality of light guides. The light-shielding ring is disposed in the receiving space and includes a plurality of through holes. The plurality of light guides are disposed in the plurality of through holes, wherein each light guide covers one or more LEDs of the lamp panel assembly.

[0050] In the above embodiments, the light guide can enhance the light emission efficiency of the LEDs it covers and form a visually appealing single-area light source. The light-shielding ring can prevent crosstalk between LEDs under adjacent light guides, and together with the light guide, multiple clear light zones can be formed. These multiple light zones can then be used to create text, images, or projected information.

[0051] Thirdly, a vehicle-mounted lighting system is provided. The vehicle-mounted lighting system includes: a control unit and vehicle-mounted lighting components; the control unit is used to control the operating status of the vehicle-mounted lighting components.

[0052] In the vehicle lighting system of this application, the operating status of the vehicle lighting components can be automatically controlled based on the control unit. The control unit can be a controller in a computing device or computing system, such as a Mobile Data Center (MDC) (or Intelligent Driving Domain Controller), Domain Controller (DC), Electronic Control Unit (ECU), etc. The DC can include a Motion Domain Controller (MDC), a Vehicle Domain Controller (VDC), etc., or it can refer to components inside the controller, such as chips. The vehicle lighting components can be mounted on the outer side of the vehicle roof. Through the control unit controlling the vehicle's multi-degree-of-freedom support, the lights can rotate to adjust their orientation, or swing along a long, narrow groove to adjust their pitch angle. This facilitates more accurate alignment of the lights with the target position, preventing the signal lights from not facing forward due to vehicle tilt, effectively reducing the probability of secondary accidents and protecting the safety of evacuees from the accident scene.

[0053] In one possible implementation of the third aspect, the vehicle lighting assembly is the vehicle lighting assembly of any of the embodiments of the second aspect above.

[0058] In the above embodiments, the second sensing module may include sensors for sensing the vehicle's driving status, such as a steering angle sensor and a braking sensor. When the second state information obtained by the second sensing module indicates that the vehicle is about to make an emergency stop or turn, the control unit can promptly and accurately control the lights to rise to the target height and display a second warning message towards the rear of the road where the vehicle is located. The second warning message may be text, images, projections, or other information. The purpose is to remind vehicles behind to pay attention to the sudden change in the vehicle's driving status, drive safely, and avoid secondary accidents caused by the driver's failure to promptly warn the following vehicles and hasty lane changes or stops, thereby improving driving safety.

[0059] In one possible implementation of the third aspect, it further includes: a third sensing module; the third sensing module is electrically connected to the control unit, the third sensing module being used to acquire third state information of the vehicle; when the third state information indicates that the vehicle is in lighting mode, the control unit controls the lamps of the vehicle lighting assembly to rise and project an illumination beam toward the target area; and / or, when the third state information indicates that the vehicle is in projection mode, the control unit controls the lamps of the vehicle lighting assembly to rise and project a projection beam toward the target area.

[0061] In one possible implementation, the third sensing module can also sense the dynamic position of the surrounding target personnel. Based on the dynamic position of the target personnel, the control unit can achieve the effect of the lighting beam following the personnel's feet, bringing a more intelligent lighting experience.

[0062] In one possible implementation of the third aspect, it further includes: a fourth sensing module; the fourth sensing module is electrically connected to the control unit, and the sensing module is used to acquire road condition information of the road ahead of the vehicle; when the road condition information indicates that an accident has occurred on the road ahead of the vehicle, the control unit controls the lights of the vehicle lighting assembly to rise and face the rear of the road where the vehicle is located to display the fourth warning information.

[0063] In the above embodiments, the fourth sensing module may include sensors for sensing the road conditions ahead of the vehicle, such as high-definition cameras and millimeter-wave radar. When the fourth state information obtained by the fourth sensing module indicates that an accident has occurred on the road ahead of the vehicle, the control unit can promptly and accurately control the lights to rise to the target height and display a second warning message towards the rear of the road where the vehicle is located. The second warning message may be text, images, projections, etc., with the purpose of reminding following vehicles that the vehicle may change its driving state due to an accident ahead, and that following vehicles should slow down and drive safely to avoid secondary accidents caused by the driver of the vehicle failing to remind the following vehicles in time and making hasty lane changes or stops, thereby improving driving safety.

The control unit can, based on the status of the vehicles behind, promptly and accurately control the lights to rise to a target height and align with the eye-target position of drivers of vehicles behind the vehicle on the road. For example, it can align with the eye-target position of the driver and / or passenger of the nearest vehicle behind, or with the eye-target position easily visible to the drivers of multiple vehicles behind. At this time, the lights display a warning message, making it easier for drivers of following vehicles to notice the warning message, effectively reminding them to drive safely and avoiding secondary accidents caused by failure to effectively warn following vehicles.

[0066] Fourthly, a vehicle-mounted multi-degree-of-freedom support system is provided. The vehicle-mounted multi-degree-of-freedom support system includes: a control unit and a vehicle-mounted multi-degree-of-freedom support base; the control unit is used to control the operating state of the vehicle-mounted multi-degree-of-freedom support base.

For example, when the movable seat needs to automatically adjust the position of devices inside the vehicle (such as displays, seats, etc.), the vehicle-mounted multi-degree-of-freedom support can be installed inside the vehicle. Alternatively, when the movable seat needs to drive devices outside the vehicle, such as warning devices, indicator lights, graphic signs, or lights and projectors, the vehicle-mounted multi-degree-of-freedom support can be installed on the outer side of the vehicle's roof. In this case, the movable seat can be located on the side of the cover facing away from the roof. By controlling the rotation of the movable seat and its swing along a long, narrow groove through the control unit, the device connected to the movable seat outside the vehicle can be accurately oriented towards the target position. For example, in the event of an accident, it can drive the warning device to accurately warn vehicles behind, making it highly practical.

[0069] In one possible implementation of the fourth aspect, the vehicle-mounted multi-degree-of-freedom support is the vehicle-mounted multi-degree-of-freedom support of any of the embodiments of the first aspect above.

[0070] In the above embodiments, the beneficial effects of the vehicle-mounted multi-degree-of-freedom support can be found in the first aspect above, and will not be repeated here.

[0071] Fifthly, a vehicle is provided. The vehicle includes a cabin; and an on-board multi-degree-of-freedom support as described in any embodiment of the first aspect, an on-board lighting assembly as described in any embodiment of the second aspect, an on-board lighting system as described in any embodiment of the third aspect, or an on-board multi-degree-of-freedom support system as described in any embodiment of the fourth aspect.

[0072] The vehicle described in this application includes at least a cabin and a multi-degree-of-freedom (DOF) support seat. Depending on the actual usage requirements, the multi-degree-of-freedom support seat can be positioned in different locations within the cabin. For example, when the movable seat needs to automatically adjust the position of devices inside the vehicle (such as displays, seats, etc.), the multi-degree-of-freedom support seat can be placed inside the cabin. Alternatively, when the movable seat needs to drive devices outside the vehicle, such as warning devices (e.g., light indicators, pattern indicators), or lights, projectors, the multi-degree-of-freedom support seat can be positioned on the top outer side of the cabin. In this case, the movable seat can be located on the side of the cover facing away from the roof. By controlling the rotation of the movable seat and its swing along a long, narrow groove through a control unit, the device connected to the movable seat outside the vehicle can be accurately oriented towards a target position. For example, in the event of an accident, the warning device can be driven to accurately warn vehicles behind, demonstrating its high practicality.

[0073] In one possible implementation of the fifth aspect, when the vehicle lighting assembly is included, the vehicle lighting assembly is located on top of the cabin; wherein, when the cover is in its initial position, the outer surface of the cover smoothly transitions with the outer surface of the cabin.

[0074] In the above embodiment, the vehicle-mounted lighting assembly is located on top of the cabin, which facilitates the transmission of interactive information to the surroundings through the lights. The cover has an initial position that allows the outer surface of the cover to smoothly transition with the outer surface of the cabin. That is, when the cover is not raised or raised to a certain position, it can be integrated with the cabin, or understood as part of the top of the cabin. This helps to improve the integration of the vehicle-mounted multi-degree-of-freedom support base with the cabin, making it easier to assemble and integrate it into a whole for use, rather than being an abrupt presence.

[0081] Figure 1 This is a structural block diagram of a vehicle 1000 provided in an embodiment of this application. Please refer to... Figure 1 This application provides a vehicle 1000, which may include a cabin 1001 and an on-board lighting system 300. The on-board lighting system 300 may include a control unit 3001 and an on-board lighting assembly 200.

[0082] This application does not limit the vehicle 1000. For example, the vehicle 1000 can be a gasoline-powered vehicle, an electric vehicle, etc. A gasoline-powered vehicle is a means of transportation that uses fossil fuels such as gasoline and diesel as power, converting the chemical energy of combustion into mechanical energy. An electric vehicle is a means of transportation that is driven by electrical energy. This application does not limit the electric vehicle. For example, an electric vehicle can be a pure electric vehicle / battery electric vehicle (pureEV / batteryEV), a hybrid electric vehicle (HEV), a range-extended electric vehicle (REEV), or a plug-in hybrid electric vehicle (PHEV), etc.

[0083] In the embodiments of this application, the control unit 3001 may be a controller in a computing device or computing system, such as a Mobile Data Center (MDC) (or Intelligent Driving Domain Controller), Domain Controller (DC), Electronic Control Unit (ECU), Microcontroller Unit (MCU), etc. The DC may include a Motion Domain Controller (MDC), a Vehicle Domain Controller (VDC), etc., or it may refer to components inside the controller, such as a chip.

[0084] The control unit 3001 can interact with the vehicle lighting assembly 200 to control the execution state of the vehicle lighting assembly 200, such as adjusting the position of the lamps in the vehicle lighting assembly 200 and the lamp's light emission mode.

[0085] Figure 2 This is a structural schematic diagram of a vehicle 1000 provided in an embodiment of this application. Figure 3 This is a schematic diagram of another vehicle 1000 provided in an embodiment of this application.

[0086] Reference Figure 2 and Figure 3 As shown, in embodiments of this application, the vehicle-mounted lighting assembly 200 can be disposed on the top of the cabin 1001, serving as a lighting lamp or an intrusion detection system (IDS) position light. Figure 2 In the example, the lamp 9 of the vehicle lighting assembly 200 can be used to display luminous patterns, such as... Figure 2 The image shows two kitten heads. Figure 3 In the example, the lamp 9 of the vehicle lighting assembly 200 can be used for illumination, such as providing a beam of light when camping. In addition, the lamp 9 of the vehicle lighting assembly 200 can also be used to emit projected beams, such as static or dynamic projected images or text. Furthermore, the lamp 9 of the vehicle lighting assembly 200 can also be used for ambient lighting, for example, by combining specific locations and patterns to achieve a customized design, creating a lighting atmosphere. As another example, the lamp 9 of the vehicle lighting assembly 200 can also be used to display warning information, such as text, graphic symbols, etc., to remind following vehicles of potential hazards ahead and to avoid obstacles in time.

[0087] Figure 4 This is a structural block diagram of another vehicle 1000 provided in an embodiment of this application.

[0088] Reference Figure 4 In embodiments of this application, the vehicle lighting system 300 of the vehicle 1000 may further include a sensing module 3002. The sensing module 3002 may include several sensors for sensing information about the vehicle's current state and surrounding environment. For example, the sensing module 3002 may include a positioning system, which may be a Global Positioning System (GPS), a BeiDou system, or other positioning systems. The sensing module 3002 may include one or more of the following: an inertial measurement unit (IMU), lidar, millimeter-wave radar, ultrasonic radar, and a camera device.

[0089] The control unit 3001 is connected to the sensing module 3002. Based on the information sensed by the sensing module 3002, the control unit 3001 can determine the control strategy for the vehicle lighting assembly 200 and adjust the position of the lamps and the light emission mode of the lamps in the vehicle lighting assembly 200.

[0090] Figure 5 This is a control flowchart of a vehicle lighting system 300 provided in an embodiment of this application.

[0091] Reference Figure 5 In one embodiment of this application, active activation can be achieved through a Human Machine Interface (HMI) soft switch, allowing the user to actively activate different application modes. For example, mode 1 could be camping lighting, mode 2 could be a custom ISD position light, and mode 3 could be an emergency signal light. After the user selects the corresponding mode, the Vehicle Information Unit / Vehicle Intranet Unit (VIU) transmits the relevant mode signal. Subsequently, the Local Dynamic Map (LDM) controls the current display of the corresponding lighting effect, that is, controls the lights in the vehicle lighting assembly 200 to display the corresponding effect, such as white light illumination, light patterns, light projection, light text, etc.; and the Microcontroller Unit (MCU) can drive the mechanical device in the vehicle lighting assembly 200 to control the lights to rise and rotate toward the target area to illuminate the target area or display light information. Figure 5 In the example, the HMI switch can be understood as the aforementioned sensing module 3002, and VIU, LDM, and MCU can be understood as the aforementioned control unit 3001.

[0092] Figure 6 A control flowchart of another vehicle lighting system 300 provided in this application embodiment.

[0093] Reference Figure 6 In one embodiment of this application, when the Advanced Driver Assistance System (ADC) determines that the vehicle has experienced an accident and has come to an emergency stop, the vehicle body camera transmits the angle between the vehicle body and the road white line. The Vehicle Identifier (VIU) receives the camera information, performs calculations, and obtains the current position angle of the vehicle body relative to the road, then transmits the corresponding CAN signal. Subsequently, the Local Dynamic Map (LDM) controls the current display of the corresponding lighting effects, that is, controls the lights in the vehicle lighting assembly 200 to display corresponding effects, such as white illumination, light patterns, light projection, light text, etc.; and the Microcontroller Unit (MCU) can drive the mechanical device in the vehicle lighting assembly 200 to control the lights to rise and rotate toward the target area, so as to illuminate the target area or display light information. Figure 6 In the example, ADS and the vehicle body camera can be understood as the aforementioned perception module 3002, and VIU, LDM, and MCU can be understood as the aforementioned control unit 3001.

[0094] In the embodiments of this application, some environmental activation conditions can also be set, and the projection can be activated after confirming that the environment meets the activation conditions. For example, the environmental activation conditions may include one or more of the following, which can be set according to actual needs during application: 1. The ambient brightness is less than 1000 lx; ​​2. The vehicle cannot move or is in P mode, and it is confirmed that a malfunction or accident has occurred; 3. There are no obstructions in the illumination path; 4. There are no vehicles in the illumination area, so as not to cause glare to vehicles approaching from behind.

[0095] Figure 7 This is an application scenario diagram of a vehicle lighting system 300 provided in an embodiment of this application.

[0096] Reference Figure 7In one embodiment of this application, when the vehicle is parked under normal driving conditions, the lamp 9 in the vehicle lighting assembly 200 can be folded onto the roof, as shown in sub-figure (1). When the vehicle is stranded due to an emergency accident, the mechanical device in the vehicle lighting assembly 200 can control the lamp 9 to rise within 3 seconds and display relevant text, such as "An accident has occurred 100m ahead, please slow down and detour" as shown in the figure; at the same time, the automatic rotation structure can ensure that the lamp 9 always faces backward, such as the lamp 9 facing the rear of the vehicle as shown in sub-figure (2), and the lamp facing the right rear of the vehicle as shown in sub-figure (3). This is to take into account the angle between the vehicle body and the lane line, so that the lamp 9 can face the rear lane, making it easier for the following vehicle to see the warning information in time. After the lamp 9 is raised, the personnel can place the warning triangle, which can improve safety. And if the raised lamp can play a sufficient warning role, it may not be necessary to risk placing the warning triangle later. Finally, the personnel evacuate to the safe area on the side of the road, as shown in sub-figure (4). The above solution helps to make the lights more accurately correspond to the target position. For example, it can prevent the traffic lights from not facing backwards when the vehicle is tilted, effectively reduce the probability of secondary accidents, and protect the safety of people evacuating from the scene of an accident.

[0097] Figures 8-12 The structural frame of the vehicle lighting system 300 provided in this application Figures 1-5 .

[0098] Reference Figure 8 As shown, in one embodiment of this application, the vehicle lighting system 300 includes a vehicle lighting assembly 200 and a control unit 3001, as well as a first sensing module 3021. The first sensing module 3021 is electrically connected to the control unit 3001 and is used to acquire first status information of the vehicle. When the first status information indicates that the vehicle has malfunctioned, the control unit 3001 controls the lights of the vehicle lighting assembly 200 to rise and face the rear of the road where the vehicle is located to display first warning information.

[0099] In the above embodiments, the first sensing module 3021 may include sensors for sensing whether the vehicle is operating normally at different locations, such as tire pressure sensors, water temperature sensors, steering angle sensors, etc. When the first state information obtained by the first sensing module 3021 indicates that the vehicle has malfunctioned, such as tire pressure below the normal threshold, water temperature too high, steering wheel malfunction, etc., the control unit 3001 can promptly and accurately control the lights to rise to the target height and face the rear of the road where the vehicle is located to display the first prompt information. The first prompt information may be text, images, projections, etc., with the purpose of reminding following vehicles to pay attention to the vehicle's malfunction, drive safely, and avoid secondary accidents caused by the driver's failure to promptly remind following vehicles and hasty lane changes or stops, thereby improving driving safety.

[0100] Reference Figure 9 As shown, in one embodiment of this application, the vehicle lighting system 300 includes a vehicle lighting assembly 200 and a control unit 3001, as well as a second sensing module 3022. The second sensing module 3022 is electrically connected to the control unit 3001 and is used to acquire second state information of the vehicle. When the second state information indicates that the driving state of the vehicle has changed or is about to change, the control unit 3001 controls the lights of the vehicle lighting assembly 200 to rise and face the rear of the road where the vehicle is located to display the second prompt information.

[0101] In the above embodiments, the second sensing module 3022 may include sensors for sensing the vehicle's driving status, such as a steering angle sensor and a braking sensor. When the second status information obtained by the second sensing module 3022 indicates that the vehicle is about to make an emergency stop or turn, the control unit 3001 can promptly and accurately control the lights to rise to the target height and display a second prompt message towards the rear of the road where the vehicle is located. The second prompt message may be text, images, projections, or other information. The purpose is to remind vehicles behind to pay attention to the sudden change in the vehicle's driving status, drive safely, and avoid secondary accidents caused by the driver's failure to promptly remind the following vehicles and hasty lane changes or stops, thereby improving driving safety.

[0102] Reference Figure 10 As shown, in one embodiment of this application, the vehicle lighting system 300 includes a vehicle lighting assembly 200 and a control unit 3001, as well as a third sensing module 3023; the third sensing module 3023 is electrically connected to the control unit 3001, and is used to acquire third state information of the vehicle; when the third state information indicates that the vehicle is in lighting mode, the control unit 3001 controls the lamps of the vehicle lighting assembly 200 to rise and project a lighting beam toward the target area; and / or, when the third state information indicates that the vehicle is in projection mode, the control unit 3001 controls the lamps of the vehicle lighting assembly to rise and project a projection beam toward the target area.

[0103] In the above embodiments, the third sensing module 3023 may include a sensor for sensing the vehicle's usage status. It is used to acquire user commands. When it is recognized that the user has turned on the lighting mode or projection mode, based on the perceived user commands, such as but not limited to touch, close-range gestures, voice operation, in-vehicle screen operation, remote terminal operation, etc., the control unit 3001 can accurately control the lamp to rise to the target height and face the target area to realize the function of projecting a lighting beam or a projection beam.

[0104] In one possible implementation, the third sensing module 3023 can also sense the dynamic position of the surrounding target personnel, and the control unit 3001 can realize the lighting beam following the personnel's feet based on the dynamic position of the target personnel, bringing a more intelligent lighting experience.

[0105] Reference Figure 11 As shown, in one embodiment of this application, the vehicle lighting system 300 includes a vehicle lighting assembly 200 and a control unit 3001, as well as a fourth sensing module 3024. The fourth sensing module 3024 is electrically connected to the control unit 3001. The sensing module is used to obtain road condition information of the road ahead of the vehicle. When the road condition information indicates that an accident has occurred on the road ahead of the vehicle, the control unit 3001 controls the lights of the vehicle lighting assembly 200 to rise and face the rear of the road where the vehicle is located to display the fourth warning information.

[0106] In the above embodiments, the fourth sensing module 3024 may include sensors for sensing the road conditions ahead of the vehicle, such as high-definition cameras and millimeter-wave radar. When the fourth state information obtained by the fourth sensing module 3024 indicates that an accident has occurred on the road ahead of the vehicle, the control unit 3001 can promptly and accurately control the lights to rise to the target height and display a second prompt message towards the rear of the road where the vehicle is located. The second prompt message may be text, images, projections, etc., with the purpose of reminding following vehicles that the vehicle may change its driving state due to an accident ahead, and that following vehicles should slow down and drive safely to avoid secondary accidents caused by the driver of the vehicle failing to remind the following vehicles in time and making hasty lane changes or stops, thereby improving driving safety.

[0107] Reference Figure 12 As shown, in one embodiment of this application, the vehicle lighting system 300 includes a vehicle lighting assembly 200 and a control unit 3001, as well as a fifth sensing module 3025; the fifth sensing module 3025 is electrically connected to the control unit 3001, and the fifth sensing module 3025 is used to obtain the position information of vehicles behind the vehicle on the road where the vehicle is located; the control unit 3001 is used to control the lights to face the target position of the driver's eyes of the vehicle behind the vehicle according to the position information of the vehicles behind the vehicle.

[0108] In the above embodiments, the fifth sensing module 3025 may include sensors for sensing the status of vehicles behind, such as high-definition cameras and millimeter-wave radar. The control unit 3001 can, based on the status of the vehicles behind, promptly and accurately control the lights to rise to a target height and to face the eye target position of drivers of vehicles behind the vehicle on the road. For example, it can face the eye target position of the driver and / or passenger of the nearest vehicle behind, or it can face the eye target position that is easily visible to the drivers of multiple vehicles behind. At this time, the lights display a warning message, which can be more easily noticed by drivers of following vehicles, effectively reminding them to pay attention to the warning message issued by the vehicle, ensuring safe driving, and avoiding secondary accidents caused by failure to effectively remind following vehicles.

[0109] The first to fifth sensing modules (3021 to 3025) mentioned above can be set individually or simultaneously. Furthermore, sensors in different modules that have the same function can share resources without needing to be configured repeatedly.

[0110] The vehicle lighting components 200 introduced above are all installed on the top of the vehicle 1000's cabin. Understandably, depending on different application requirements, the vehicle lighting components 200 can also be installed in other locations on the cabin to achieve automatic adjustment and use of the lights.

[0111] The preceding text has focused on the vehicle 1000 and the vehicle lighting system 300 of the embodiments of this application. The following text will describe in detail some embodiments of the vehicle multi-degree-of-freedom support 100 and the vehicle lighting assembly 200 of this application.

[0112] Figure 13 This is a structural diagram of a vehicle-mounted multi-degree-of-freedom support 100 provided in an embodiment of this application. Figure 14 for Figure 13 Structural diagram of the middle cover body. Figure 15 for Figure 13 The structural diagram of region A from another perspective.

[0113] Please refer to Figures 13-15 As shown in the embodiment of this application, the vehicle-mounted multi-degree-of-freedom support 100 includes: a cover 1, a first drive assembly 3, and a movable seat 2. The cover 1 has a connecting portion 101 that connects the inner side and the outer side of the cover 1. The connecting portion 101 is configured as an elongated groove along a direction parallel to the cover 1. The first drive assembly 3 is disposed on the inner side of the cover 1. The movable seat 2 is disposed on the outer side of the cover 1. The movable seat 2 includes a first connecting member 21 that extends through the connecting portion 101 into the inner side of the cover 1 and connects to the first drive assembly 3. The first drive assembly 3 is used to drive the movable seat 2 to rotate and / or swing along the elongated groove.

[0114] In this design, the side of the cover 1 facing the movable seat 2 is the outer side, and the side of the cover 1 facing the first drive assembly 3 is the inner side. The inner side of the cover 1 is opposite to the outer side of the cover 1. For example, the outer side may refer to the side that may be exposed during subsequent use, and the inner side may refer to the side that may be hidden during subsequent use and not intended to be directly seen by the naked eye.

[0115] The connecting part 101 of the cover 1 can be understood as a through hole that extends from the outside of the cover 1 to the inside of the cover 1. This through hole is constructed in a transverse strip shape, that is, the cross section of the hole perpendicular to the through direction is in a strip shape, so that a strip-shaped groove can be constructed in the direction parallel to the cover 1.

[0116] A long, narrow groove can be understood as having two hole walls (a1, a2) extending along the length of the connecting part, such as... Figure 14 As shown, the two hole walls (a1, a2) are opposite each other, thereby forming a limiting space that allows the first connector 21 to swing along the length direction of the connecting part, so that the first connector 21 is not easy to sway left and right when it swings along the length direction of the connecting part, that is, it is not easy to sway along the width direction of the connecting part.

[0117] After the first connecting member 21 of the movable seat 2 passes through the connecting part 101 and extends into the inner side of the cover 1, that is, after passing through the long strip groove, the first connecting member 21 of the movable seat 2 can rotate within the connecting part 101 and swing along the length direction of the long strip groove formed by the connecting part 101, thus realizing the change of the two degrees of freedom of the movable seat 2.

[0118] For example, the first connector 21 can be a connecting rod, not limited to cylindrical rods, square rods, etc.

[0119] like Figure 15 As shown, the first drive component 3 is connected to the first connector 21 on the inner side of the cover 1. This allows the first drive component 3 to drive the first connector 21 and the movable seat 2 to achieve two-way freedom of movement, thus realizing the automatic control function of the movable seat 2. The first drive component 3 is located on the inner side of the cover 1, and the cover 1 can also achieve a hidden or semi-hidden design for the first drive component 3, which helps protect it from damage caused by external dust and other environmental factors, and improves the overall neatness of the appearance.

[0120] The cover 1 can be installed in different positions on the vehicle according to actual usage needs. For example, when the movable seat 2 needs to automatically adjust the position of devices inside the vehicle (such as displays, seats, etc.), the cover 1 can be installed inside the vehicle. Alternatively, when the movable seat 2 needs to drive devices outside the vehicle, such as warning devices, light indicators, graphic indicators, or lights, projection lights, the cover 1 can be installed on the outer side of the vehicle's roof. In this case, the movable seat 2 can be located on the side of the cover 1 facing away from the roof. By controlling the rotation of the movable seat 2 and its swing along the long, narrow groove through the first drive assembly 3, the device connected to the movable seat 2 outside the vehicle can be accurately oriented towards the target position. For example, in the event of an accident, the warning device can be driven to accurately warn vehicles behind, making it highly practical.

[0121] When the external warning device of a vehicle is a signal light (such as the light fixture 9 described above), the high warning effect of the light can be used to convey the signal that the vehicle and road users want to release, helping to improve the safety of personnel evacuation in the event of an accident. Compared with the fact that general vehicle lights are fixed and difficult to transmit effective information over long distances, and that effective signal lights such as general marker lights are fixed to the ground and difficult to quickly help people in the vehicle complete signal transmission in the event of a traffic accident, the vehicle-mounted multi-degree-of-freedom support 100 provided in this application can realize vehicle-mounted and multi-degree-of-freedom automatic rotation, thereby preventing the problem that the signal light cannot face backward due to vehicle tilting, effectively reducing the probability of secondary accidents and protecting the safety of personnel evacuating from the scene of an accident.

[0122] Reference Figure 15 As shown, in one embodiment of this application, the first drive assembly 3 includes: a first bevel gear 31, a second bevel gear 32, a third bevel gear 33, a first motor 301, and a second motor 302. The first bevel gear 31 and the second bevel gear 32 are arranged in a mirror-symmetrical manner. The third bevel gear 33 is located between the first bevel gear 31 and the second bevel gear 32, and meshes with both the first bevel gear 31 and the second bevel gear 32. The third bevel gear 33 is also fixed to the first connecting member 21. The first motor 301 drives the first bevel gear 31 to rotate, and the second motor 302 drives the second bevel gear 32 to rotate.

[0123] In the above embodiments, the first bevel gear 31 and the third bevel gear 33 form an orthogonal transmission pair, and the second bevel gear 32 and the third bevel gear 33 also form an orthogonal transmission pair. When the first motor 301 and the second motor 302 drive the first bevel gear 31 and the second bevel gear 32 at the same speed and in the same direction, the third bevel gear 33 rotates around the axis of the first bevel gear 31 and the second bevel gear 32, thereby driving the first connecting member 21 and the movable seat 2 to swing along the length of the elongated groove. When the first motor 301 and the second motor 302 drive the first bevel gear 31 and the second bevel gear 32 at the same speed and in opposite directions, the third bevel gear 33 rotates around its own axis, thereby driving the first connecting member 21 and the movable seat 2 to rotate. When the first motor 301 and the second motor 302 drive the first bevel gear 31 and the second bevel gear 32 at different speeds and in opposite directions, the third bevel gear 33 rotates around its own axis and also rotates around the axis of the first bevel gear 31 and the second bevel gear 32, thereby driving the first connecting member 21 and the movable seat 2 to rotate and swing along the length of the elongated groove, achieving a compound motion. In practical applications, the two motors can be used to control the movable seat 2 to move in a suitable manner according to the specific application requirements of the scenario, so as to quickly move to the target position.

[0124] In one embodiment of this application, such as Figure 15 As shown, the first motor 301 and the second motor 302 are arranged opposite to each other and fixed, and the first bevel gear 31 and the second bevel gear 32 are located between the first motor 301 and the second motor 302.

[0125] In the above embodiments, the first motor 301, the second motor 302, the first bevel gear 31, and the second bevel gear 32 are arranged in a linear layout, which helps to reduce the size along the radial direction of the motor and makes the layout more compact. When arranged on the roof of the vehicle, the axis of the motor can correspond to the left and right direction of the vehicle. In this way, the space occupied in the front and rear directions of the roof will be very small, without affecting the arrangement of other structures (such as sunroof).

[0126] Figure 16 This is a structural block diagram of a first driving component 3 provided in an embodiment of this application.

[0127] Reference Figure 16 As shown, in one embodiment of this application, the first drive assembly 3 further includes a first reduction mechanism 303 and a second reduction mechanism 304. The first reduction mechanism 303 is disposed between the output end of the first motor 301 and the first bevel gear 31. The second reduction mechanism 304 is disposed between the output end of the second motor 302 and the second bevel gear 32.

[0128] In the above embodiment, the first reduction mechanism 303 can convert the kinetic energy output by the first motor 301 from high speed and low torque to low speed and high torque, thereby controlling the rotation of the first bevel gear 31 more smoothly. The second reduction mechanism 304 can convert the kinetic energy output by the second motor 302 from high speed and low torque to low speed and high torque, thereby controlling the rotation of the second bevel gear 32 more smoothly. With this design, when the first bevel gear 31 and the second bevel gear 32 drive the third bevel gear 33 simultaneously, the movement is more stable and reliable, and problems such as stripping and tooth breakage are less likely to occur.

[0129] Figure 17 This is a schematic diagram of the structure of a first bevel gear, a second bevel gear, or a third bevel gear provided in the embodiments of this application.

[0130] Reference Figure 17 As shown, in one embodiment of this application, the first bevel gear 31 includes: a plurality of first teeth 311, a first limiting portion 312, and a second limiting portion 313. The plurality of first teeth 311 are arranged circumferentially along the first bevel gear 31 and are used to mesh with a third bevel gear 33; the first limiting portion 312 is disposed on one side of the plurality of first teeth 311 along the circumferential direction of the first bevel gear 31; the second limiting portion 313 is disposed on the other side of the plurality of first teeth 311 along the circumferential direction of the first bevel gear 31. The second bevel gear 32 includes: a plurality of second teeth 321, a third limiting portion 322, and a fourth limiting portion 323. The plurality of second teeth 321 are arranged circumferentially along the second bevel gear 32 and are used to mesh with the third bevel gear 33; the third limiting portion 322 is disposed on one side of the plurality of second teeth 321 along the circumferential direction of the second bevel gear 32; the fourth limiting portion 323 is disposed on the other side of the plurality of second teeth 321 along the circumferential direction of the second bevel gear 32.

[0131] In the above embodiment, the first limiting part 312 and the second limiting part 313 limit the two ends of the plurality of first teeth 311 arranged circumferentially on the first bevel gear 31, so that when the plurality of first teeth 311 of the first bevel gear 31 mesh with the third bevel gear 33, when meshing to the first limiting part 312, they will be restricted from continuing to mesh and transmit in the direction away from the first teeth 311 towards the first limiting part 312, and when meshing to the second limiting part 313, they will be restricted from continuing to mesh and transmit in the direction away from the first teeth 311 towards the second limiting part 313. Similarly, the third limiting part 322 and the fourth limiting part 323 limit the two ends of the plurality of second teeth 321 arranged circumferentially on the second bevel gear 32. When the plurality of second teeth 321 of the second bevel gear 32 mesh with the third bevel gear 33, the meshing at the third limiting part 322 will restrict the meshing transmission to continue in the direction away from the second teeth 321 towards the third limiting part 322, and the meshing at the fourth limiting part 323 will restrict the meshing transmission to continue in the direction away from the first teeth 311 towards the fourth limiting part 323. Through the above solution, the excessive rotation of the third bevel gear 33 and / or excessive oscillation along the length of the elongated groove can be prevented, thereby preventing the movable seat connected to the third bevel gear 33, and the device (such as a lamp) subsequently mounted on the movable seat from excessive rotation and / or oscillation, so as to improve the collision risk caused by excessive rotation. For example, when the roof lamp is rotating, it is less likely to collide with the vehicle roof or glass due to excessive rotation.

[0132] The size and number of the multiple first teeth 311 and the multiple second teeth 321 are not limited here. They can be determined later based on the design rotation and swing angles and transmission accuracy of the device actually installed on the movable seat, which are not likely to interfere with the surrounding structure.

[0133] Reference Figure 17 As shown, in one embodiment of this application, the third bevel gear 33 includes: a plurality of third teeth 331, a fifth limiting portion 332, and a sixth limiting portion 333. The plurality of third teeth 331 are arranged circumferentially along the third bevel gear 33 and are used to mesh with the first bevel gear 31 and the second bevel gear 32; the fifth limiting portion 332 is disposed on one side of the plurality of third teeth 331 along the circumferential direction of the third bevel gear 33; the sixth limiting portion 333 is disposed on the other side of the plurality of third teeth 331 along the circumferential direction of the third bevel gear 33.

[0134] In the above embodiment, the fifth limiting part 332 and the sixth limiting part 333 limit both ends of the plurality of third teeth 331 arranged circumferentially on the third bevel gear 33. When the plurality of third teeth 331 of the third bevel gear 33 simultaneously mesh with the first bevel gear 31 and the second bevel gear 32, the meshing at the fifth limiting part 332 will restrict the meshing transmission to continue in the direction away from the third teeth 331, and the meshing at the sixth limiting part 333 will restrict the meshing transmission to continue in the direction away from the third teeth 331. Through the above solution, the excessive rotation of the third bevel gear 33 can be further prevented, thereby preventing the movable seat connected to the third bevel gear 33 and the device (such as a lamp) subsequently installed on the movable seat from excessively rotating, so as to improve the collision risk caused by excessive rotation. For example, when the roof lamp is rotating, it is not easy to collide with the vehicle roof or glass due to excessive rotation.

[0135] The size and number of the multiple third teeth 331 are not limited here. They can be determined later based on the design rotation and swing angles and transmission accuracy of the device actually installed on the movable seat, which are not likely to interfere with the surrounding structure.

[0136] In one embodiment of this application, refer back to Figure 13 The vehicle-mounted multi-degree-of-freedom support 100 further includes: a fixed base 5, a telescopic frame 6, and a second drive assembly 7. The fixed base 5 is used to connect to the vehicle. The telescopic frame 6 is disposed between the fixed base 5 and the cover 1. The second drive assembly 7 is disposed on the fixed base 5 and connected to the telescopic frame 6 and / or the cover 1 for driving the cover 1 to rise and fall relative to the fixed base.

[0137] In the above embodiment, the fixed base 5 can be fixed to the vehicle, providing stable support. The telescopic frame 6 between the cover 1 and the fixed base 5 allows the cover 1 to be raised or lowered relative to the fixed base 5. The second drive assembly 7 enables the automatic raising and lowering function of the cover 1. When the telescopic frame 6 is in the retracted state, the cover 1 can be fastened to the fixed base 5, forming a flat structure with reduced space occupation. When the telescopic frame 6 is in the extended state, the cover 1 moves away from the fixed base 5, which is equivalent to raising the cover 1 to a certain height. This allows the connected devices above the movable base 2 to be raised to a higher position, such as raising the interior seats, display screens, etc., and raising the exterior traffic lights to make them more visible to surrounding people.

[0138] In one embodiment of this application, such as Figure 13As shown, the telescopic frame 6 includes at least two cross-shaped linkage groups 60, which are arranged at intervals along a direction parallel to the cover 1; wherein, the cross-shaped linkage group 60 includes a first link 61 and a second link 62 that are arranged in a cross configuration, the first link 61 and the second link 62 are hinged at the cross position, the first end of the first link 61 and the first end of the second link 62 are rotatably connected to different positions of the fixed base 5, and the second end of the first link 61 and the second end of the second link 62 are rotatably connected to different positions of the cover 1.

[0139] In the above embodiment, the cross-shaped linkage group 60 has a simple structure and is easy to store. On the one hand, it can effectively support the cover 1 when unfolded, and on the other hand, it can reduce space occupation when retracted. Here, at least two cross-shaped linkage groups 60 arranged at intervals along a direction parallel to the cover 1 can play a role in stabilizing and supporting the cover 1. The structure is simple and the connection is reliable.

[0140] For example, the fixed base 5 may include a rotating support shaft 601, and the first end of the first connecting rod 61 and the first end of the second connecting rod 62 may be connected to the rotating support shaft 601 via bearings 602 respectively. This makes it less likely for the telescopic frame 6 to jam when it extends or retracts, resulting in smoother movement.

[0141] For example, the cover 1 may also include a rotating support shaft, and the second ends of the first connecting rod 61 and the second connecting rod 62 may be connected to the rotating support shaft via bearings, respectively. This ensures that the telescopic frame 6 and the cover 1 are less prone to jamming during telescopic movement, resulting in smoother motion.

[0142] In one embodiment of this application, such as Figure 13 As shown, the second drive assembly 7 includes a hydraulic cylinder 71 and a hydraulic push rod 72 that cooperate with each other. The hydraulic cylinder 71 is disposed on the fixed base 5. One end of the hydraulic push rod 72 extends into the hydraulic cylinder 71, and the other end is hinged to the telescopic frame 6 or fixedly connected to the cover 1.

[0143] In the above embodiments, under the action of hydraulic pressure, the exposed end of the hydraulic push rod 72 can be pushed to extend and retract further, thereby driving the telescopic frame 6 to move the cover 1, or directly driving the cover 1 to move. Since the angle of the connecting rod in the telescopic frame 6 changes, the hydraulic push rod 72 can be hinged to the connecting rod. However, when connected to the cover 1, it can be directly fixed along the lifting direction, without involving angle changes.

[0144] In another embodiment of this application, the second drive component 7 includes a motor and a transmission mechanism such as gears and / or hinges. The hydraulic cylinder and hydraulic push rod can be replaced by the transmission mechanism such as the motor and gears and / or hinges to drive the cover to rise and fall. This design has the advantage of occupying little space, which is conducive to achieving a compact space miniaturized layout and thus reducing the overall structural size.

[0145] In one embodiment of this application, the vehicle-mounted multi-degree-of-freedom support 100 further includes: a buffer structure 12, disposed on the side of the cover 1 facing the fixed seat 5 (e.g., Figure 13 (as shown), and / or disposed on the side of the fixing seat 5 facing the cover 1.

[0146] In the above embodiments, the buffer structure 12 can be made of materials such as foam that have stress-buffering and sound-absorbing properties. This makes it less prone to frictional wear when the cover 1 and the fixing seat 5 are in contact, and also less likely to produce abnormal noise, which helps to improve the comfort of using the product.

[0147] For example, refer to Figure 13 As shown, the buffer structure 12 includes a first buffer 121 and a second buffer 122, which are disposed on both sides of the cover 1 and / or both sides of the fixing seat 5 in a direction parallel to the cover 1.

[0148] In the above example, the first buffer 121 and the second buffer 122 can effectively buffer and muffle noise.

[0149] In one embodiment of this application, such as Figure 13 As shown, the cover 1 has a retaining edge 11 around its perimeter, which protrudes toward the fixing seat 5.

[0150] In the above embodiment, the flanges 11 protruding from the perimeter of the cover 1 toward the fixing seat 5 can hide and protect the first drive assembly 3 and telescopic frame 6 and other structures inside the cover 1, and the overall appearance can be neater.

[0151] In one embodiment of this application, when the cover 1 and the fixed seat 5 are fastened together, the stop 11 along the movement direction of the cover 1 can abut against the fixed seat 5, thereby forming a certain height space between the cover 1 and the fixed seat 5 for accommodating and protecting structures such as the first drive component 3.

[0152] In one embodiment of this application, when the cover 1 and the fixing seat 5 are fastened together, the retaining edge 11 can protect the surrounding area of ​​the fixing seat 5, thereby surrounding the fixing seat 5 inside the cover 1, resulting in better overall structure and higher integration.

[0153] In one embodiment of this application, such as Figure 13 and Figure 15As shown, the movable seat 2 also includes a second connector 22, which protrudes toward the side of the movable seat 2 opposite to the first connector 21.

[0154] In the above embodiment, the second connector 22, which protrudes towards the side of the movable base 2 opposite to the first connector 21, can be raised in height, allowing the device structure connected to the second connector 22 to be positioned at a higher position. For example, when connecting a lamp through the second connector 22, the lamp can be raised to a higher position.

[0155] For example, the second connector 22 can be a connecting rod, not limited to cylindrical rods, square rods, etc.

[0156] Figure 18 This is a structural diagram of a vehicle lighting assembly provided in an embodiment of this application. Figure 19 for Figure 18 A schematic diagram of the structure of the lamp.

[0157] Please refer to Figure 18 and Figure 19 As shown, this application embodiment also provides a vehicle-mounted lighting assembly 200. The vehicle-mounted lighting assembly 200 includes: the vehicle-mounted multi-degree-of-freedom support 100 of the previous embodiment; and a lighting fixture 9, connected to the movable seat 2 of the vehicle-mounted multi-degree-of-freedom support 100, for example, it can be connected to the second connector 22 of the movable seat 2.

[0158] In the vehicle-mounted lighting assembly 200 of this application embodiment, the function and role of the vehicle-mounted multi-degree-of-freedom support 100 are as described above. It can automatically control the rotation of the movable seat 2 and / or swing along the elongated slide. The lamp 9 can be connected to the movable seat 2, for example, it can be connected to the second connecting member 22 on the movable seat 2, thereby increasing the installation height and improving the radiation range of the lamp 9. The connection between the lamp 9 and the vehicle-mounted multi-degree-of-freedom support 100 allows the lamp 9 to rotate to adjust its orientation, and it can also swing along the direction corresponding to the elongated slide to adjust its pitch angle. This helps the lamp 9 to more accurately correspond to the target position. For example, it can prevent the signal light from not facing backward due to vehicle tilting, effectively reducing the probability of secondary accidents and protecting the safety of personnel evacuating from the accident scene.

[0159] For example, the luminaire is used to provide one or more of the following: illumination, projection, ambiance design, and cueing information; the cueing information includes one or more of the following: text cueing information, graphic cueing information, and strobe cueing information.

[0160] In the examples above, "lighting" refers to emitting ordinary light beams, such as white or colored beams. For instance, it can illuminate the campsite in a camping party setting, or provide foot-tracking lighting for pedestrians, such as a tracking light carpet. "Projection" refers to emitting projected light beams, such as projecting images or text information. The projected information can be static or dynamic. "Ambient lighting" combines specific locations and patterns to create customized designs, achieving a lighting atmosphere effect. "Lighting fixtures used to display prompts" means that the fixtures can send alerts to the outside world, such as by directly displaying illuminated text, illuminated images, or flashing information at specific frequencies to issue warnings or distress signals. These solutions enhance the vehicle's intelligent interaction with the outside world.

[0161] For example, when the first connector is in the first position of the elongated groove, the luminous surface of the lamp 9 can be perpendicular to the cover 1. When the first connector is in the second position of the elongated groove, the luminous surface of the lamp 9 forms an acute or obtuse angle with the cover 1.

[0162] In the above example, when the first connector is moved to different positions in the elongated slide, the lamp 9 set on the movable seat 2 will move to the corresponding different positions. For example, when the first connector is in the first position, the light-emitting surface of the lamp 9 is perpendicular to the cover 1, while when the first connector is in the second position, the light-emitting surface of the lamp 9 can form an acute angle or an obtuse angle with the cover 1. That is, by changing the position of the first connector in the elongated slide, the angle between the light-emitting surface of the lamp 9 and the cover 1 can be adjusted, so as to control the light-emitting surface of the lamp 9 to face the required position height and achieve more precise light control.

[0163] In one embodiment of this application, reference is made to Figure 19 As shown, the lamp 9 includes a rear housing 91, a lampshade 92, and a lamp panel assembly 93. The rear housing 91 and the lampshade 92 are interlocked to form an accommodating space. The lamp panel assembly 93 is disposed within the accommodating space. The rear housing 91 and the lampshade 92 can be connected and fixed together by means of snap-fit, screws, or other methods.

[0164] In the above embodiment, the rear shell 91 can be connected to the second connector 22 of the movable base 2, thereby fixing the lamp 9 to the movable base 2. The receiving space formed by the rear shell 91 and the lamp cover 92 can accommodate the lamp board assembly 93, thereby protecting the lamp board assembly 93. The light emitted by the lamp board assembly 93 can be emitted to the outside of the lamp cover 92 via the lamp cover 92. The lamp board assembly 93 may include a circuit base plate 931 and a plurality of lamp beads 932 located on the circuit base plate 931, and the lamp beads 932 may be LED lamp beads.

[0165] In one embodiment of this application, the lampshade 92 may include a textured structure 921, which can be used to generate uniform light, improve the uniformity of light output, and avoid producing glaring bright spots through the lampshade.

[0166] In one embodiment of this application, reference is made to Figure 19 As shown, the lamp 9 also includes a heat dissipation assembly 95, which is disposed on the outside of the rear housing 91.

[0167] In the above embodiments, the heat dissipation component 95 connected to the rear housing 91 can dissipate heat to the external environment when the lamp panel assembly 93 is continuously operating and generating heat, reducing the risk of thermal damage to the lamp panel assembly 93. The heat dissipation component 95 can dissipate heat through methods such as air cooling or water cooling. Water cooling can include liquid cooling pipes, which can be in contact with the rear housing or integrated into the rear housing. Air cooling can include multiple spaced-apart heat dissipation fins.

[0168] In one embodiment of this application, reference is made to Figure 19 As shown, the luminaire 9 also includes a light-shielding ring 941 and a plurality of light guides 942. The light-shielding ring 941 is disposed in the receiving space and includes a plurality of through holes. The plurality of light guides 942 are disposed in the plurality of through holes, wherein each light guide 942 covers one or more lamp beads 932 of the lamp panel assembly 93.

[0169] In the above embodiments, the light guide 942 can enhance the light emission efficiency of the LED beads 932 it covers and form a visually appealing single-area light source. The light-shielding ring 941 can prevent crosstalk between the light from LED beads 932 under adjacent light guides 942, and together with the light guide 942, multiple clear light areas can be formed. These multiple light areas can then be used to form text, images, or projected prompts.

[0170] In one embodiment of this application, the vehicle lighting assembly 200 is located on top of the vehicle cabin, and when the cover 1 is in its initial position, the outer surface of the cover 1 smoothly transitions with the outer surface of the cabin.

[0171] In the above embodiment, the vehicle-mounted lighting assembly 200 is located on top of the cabin, which facilitates the transmission of interactive information to the surroundings through the lights therein. The cover 1 has an initial position, allowing the outer surface of the cover 1 to smoothly transition with the outer surface of the cabin. That is, when the cover 1 is not raised or raised to a certain position, it can be integrated with the cabin, or understood as part of the top of the cabin. This helps to improve the integration degree between the vehicle-mounted multi-degree-of-freedom support 100 and the cabin, making it easier to assemble and integrate it into a whole for use, rather than becoming an abrupt presence.

[0172] Figure 20 This is a structural block diagram of a vehicle-mounted multi-degree-of-freedom support system 400 provided in an embodiment of this application.

[0173] Based on the vehicle-mounted multi-degree-of-freedom support 100, vehicle-mounted lighting assembly 200, and vehicle-mounted lighting system 300 described above in the embodiments of this application, some embodiments of this application also provide a vehicle-mounted multi-degree-of-freedom support system 400.

[0174] The vehicle-mounted multi-degree-of-freedom support system 400 of this application includes: a control unit 3001 and a vehicle-mounted multi-degree-of-freedom support base 100 of the previous embodiment. The control unit is used to control the operating state of the vehicle-mounted multi-degree-of-freedom support base.

[0175] In the vehicle-mounted multi-degree-of-freedom support system 400 of this application embodiment, the operating state of the vehicle-mounted multi-degree-of-freedom support seat 100 can be automatically controlled based on the control unit 3001. The explanation of the control unit 3001 can be found above, and will not be repeated here.

[0176] The vehicle-mounted multi-degree-of-freedom support 100 can be installed in different locations within the vehicle according to actual usage needs. For example, when the movable seat needs to automatically adjust the position of devices inside the vehicle (such as displays, seats, etc.), the vehicle-mounted multi-degree-of-freedom support 100 can be installed inside the vehicle. Alternatively, when the movable seat needs to drive devices outside the vehicle, such as warning devices, light indicators, graphic indicators, or lights and projectors, the vehicle-mounted multi-degree-of-freedom support 100 can be installed on the outer side of the vehicle's roof. In this case, the movable seat can be located on the side of the cover facing away from the roof. Control unit 3001 controls the rotation of the movable seat and its swing along the long, narrow groove, allowing the device connected to the movable seat outside the vehicle to accurately face the target position. For example, in the event of an accident, it can drive the warning device to accurately warn vehicles behind, making it highly practical.

[0177] Figure 21 This is a structural block diagram of another vehicle-mounted multi-degree-of-freedom support system 400 provided in an embodiment of this application.

[0178] In one embodiment of this application, reference is made to Figure 21 As shown, the vehicle-mounted multi-degree-of-freedom support system 400 may also include a sensing module 3002. The explanation of the sensing module 3002 can be found in the previous text and will not be repeated here.

[0179] The control unit 3001 is connected to the sensing module 3002. Based on the information sensed by the sensing module 3002, the control unit 3001 can determine the control strategy for the vehicle multi-degree-of-freedom support 100 and adjust the position and state of the structure (such as lamps, seats, displays, etc.) supported by the vehicle multi-degree-of-freedom support 100.

[0180] Figure 22This is a structural block diagram of another vehicle 1000 provided in an embodiment of this application. (Refer to...) Figure 22 As shown, the vehicle 1000 in this embodiment of the application may include an onboard multi-degree-of-freedom support system 400 disposed in the cabin 1001. Compared to Figure 4 In this embodiment, the vehicle-mounted multi-degree-of-freedom support system 400 may not include... Figure 4 The lamps in the vehicle lighting system 300 in this embodiment can be replaced with other structures, such as seats, in-vehicle displays, etc. Other functions and effects can be found in the preceding text and will not be repeated here.

[0181] 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.
