However, with the development of automotive intelligence, there are new demands for interactive features in lighting carpets. Dynamic lighting carpets can significantly improve the interaction between automotive lighting carpets and drivers / passengers. Furthermore, since lighting carpet devices are exposed to the elements, after a period of driving, the windows of the carpet are easily covered by dirt and dust, preventing proper light projection. Summary of the Invention

Detailed Implementation

[0041] To enable those skilled in the art to better understand the technical solution of this application, the dynamic light carpet device and vehicle of this application will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0042] This application provides a dynamic light carpet device for use when vehicles are welcoming guests, which can project patterns onto the ground. Combined with... Figure 1A , Figure 1B , Figure 1C As shown, the dynamic light carpet device includes a fixed support 10, a light carpet module 20, a drive module 30, and other structures.

[0043] The fixed bracket 10 is the basic structure of the entire dynamic light carpet device, supporting other structures. The fixed bracket 10 is fixedly mounted to the vehicle body and can be installed on the chassis or the lower part of the door, close to the ground, so as to project images onto the ground or other locations.

[0044] The light blanket module 20 is rotatably mounted on the fixed bracket 10 about a pivot axis along a first direction; the first direction is as follows: Figure 1A As shown on the X-axis, the light carpet module 20 is mounted on the fixed bracket 10 via a rotating shaft extending along the first direction, thus allowing the light carpet module 20 to rotate relative to the fixed bracket 10 around the first direction. The light carpet module 20 is provided with a projection window for projecting patterns. The light from the light carpet module 20 is projected to the outside through the projection window, and the angle of the light projected by the projection window is at an angle to the first direction, for example, 90 degrees. When the light carpet module 20 rotates around the rotating shaft, the angle of the pattern projected from the projection window changes, thereby creating a dynamic effect on the ground.

[0045] The housing of the drive module 30 is fixedly mounted on the fixed bracket 10. The output shaft 330 of the drive module 30 extends along a first direction and is connected to the light blanket module 20 to drive the light blanket module 20 to rotate around the axis in the first direction. Figure 4 As shown, the end of the output shaft 330 is provided with a spline, which can be inserted into the keyway provided on the side wall of the light blanket module 20.

[0046] Combination Figure 1B As shown, when the light carpet module 20 is in the folded position, its projection window is blocked by the fixed bracket 10. That is, the projection window of the light carpet module 20 faces the surface of the fixed bracket 10. The side wall of the fixed bracket 10 acts as a shield, preventing external contaminants such as mud and water from polluting the projection window and ensuring it remains in a projectable state. Combined with... Figure 1A As shown, when the light carpet module 20 is in the working position, the projection window of the light carpet module 20 projects a pattern outward and downward, forming a preset pattern on the ground and other positions. Since the driving module 30 can drive the light carpet module 20 to rotate around the first direction, a dynamic projection effect is formed on the ground.

[0047] This application achieves dynamic projection by rotating the light carpet module 20, forming an interaction between the automotive lighting light carpet and the user, thus enhancing the user experience; when the light carpet module 20 is folded, it is protected by the fixed bracket 10 to prevent the light carpet module 20 from being contaminated.

[0048] Combination Figure 2 As shown, the fixing bracket 10 of this application includes a first side plate 110, a second side plate 120, and a third side plate 130. The first side plate 110 and the third side plate 130 are perpendicular to the first direction, and the second side plate 120 is parallel to the first direction. The first side plate 110 and the third side plate 130 are respectively fixedly and perpendicularly at both ends of the second side plate 120. The first side plate 110, the second side plate 120, and the third side plate 130 form a U-shaped groove structure.

[0049] The two ends of the rotating shaft of the light carpet module 20 are respectively rotatably mounted on the first side plate 110 and the third side plate 130. When the light carpet module 20 is retracted, the projection window of the light carpet module 20 is blocked by the second side plate 120. At this time, the projection window of the light carpet module 20 faces upward and is perpendicular to the second side plate 120. The entire light carpet module 20 enters the U-shaped groove formed by the first side plate 110, the second side plate 120 and the third side plate 130.

[0050] Combination Figure 1AAs shown, the fixed bracket 10 adopts a U-shaped groove structure with no solid structure at the bottom, so that the light blanket module 20 will not be interfered with when it rotates diagonally downwards; the rotation axis of the light blanket module 20 is directly opposite the first side plate 110 and the third side plate 130 near the lower part, and a large space is reserved between the rotation axis and the second side plate 120 for the light blanket module 20 to enter.

[0051] The fixed bracket 10 has no solid plate surface obstruction structure at the front and rear along the second direction (Y axis), so that the front light blanket module 20 can swing to avoid it, and the rear light drive module 30 can avoid it.

[0052] Combination Figure 1C , Figure 2 As shown, the second side plate 120 is provided with a limiting block 121. The limiting block 121 protrudes from the surface of the second side plate 120. When the light blanket module 20 is retracted, it is blocked and limited by the limiting block 121. The limiting block 121 is used to limit the extreme position of the light blanket module 20 when it is retracted, and to prevent the light blanket module 20 from rotating excessively.

[0053] It should be noted that the light carpet module 20 can reach the folding position by controlling the driving angle of the drive module 30. Under normal circumstances, the light carpet module 20 does not contact the limit block 121 when it stops at the folding position. If the light carpet module 20 does not stop normally, it is stopped by the limit block 121. The drive module 30 drives the light carpet module 20 to contact the limit block 121, and stops driving when the output torque reaches the predetermined value.

[0054] Combination Figure 4 As shown, the drive module 30 of this application includes a motor 310 and a gearbox 320. The motor 310 can be a stepper motor, a brushed DC motor, a brushless DC motor, a ripple motor, etc. The drive shaft of the motor 310 drives the gearbox 320. The gearbox 320 has several gears with different gear ratios inside. The motor 310 reduces its output speed and increases its torque through the gearbox 320. The gearbox 320 is used to drive the output shaft 330 to rotate, and the output shaft 330 in turn drives the light blanket module 20 to rotate.

[0055] Combination Figure 1A As shown, the dynamic light carpet device of this application also includes a damping module 40, which dampens the rotation of the light carpet module 20. By setting the damping module 40, the suspension force of the light carpet module 20 is increased, eliminating the swaying caused by structural gaps. Combined with... Figure 5A , Figure 5B As shown, the damping module 40 includes a damping shell 410, a damping shaft 420, an elastic element 430, and a sliding friction plate 440. The damping shell 410 is fixed to the fixed bracket 10 and serves as the outer shell of the entire damping module 40. The damping shaft 420 is rotatably mounted on the damping shell 410 along a first direction, in conjunction with... Figure 5BAs shown, the damping shaft 420 and the damping shell 410 form two rotational engagement positions, providing stable support for the damping shaft 420. The damping shaft 420 is assembled into the light carpet module 20, and the damping shaft 420 rotates synchronously with the light carpet module 20. The elastic element 430 can be a helical spring. Figure 5A As shown, a spline is provided at the end of the damping shaft 420, which can be inserted into the keyway provided on the side wall of the light blanket module 20. The damping shaft 420 and the output shaft 330 are coaxially arranged.

[0056] The sliding friction plate 440 is circumferentially fixed to the damping shaft 420, and the sliding friction plate 440 rotates synchronously with the light blanket module 20. The sliding friction plate 440 presses against one end of the elastic member 430, and the elastic member 430 applies an elastic force to the sliding friction plate 440 along a first direction. The end faces of the sliding friction plate 440 and the damping shell 410 form surface contact, and the sliding friction plate 440 generates damping by contacting the damping shell 410. The magnitude of the damping can be adjusted by changing the elastic force of the elastic member 430; the greater the elastic force of the elastic member 430, the greater the damping.

[0057] Combination Figure 5B As shown, the damping shell 410 includes a base shell 411 and a pressure plate 412. The base shell 411 includes a cylindrical shell and a bottom surface disposed at one end of the cylinder. The pressure plate 412 is a circular plate with a certain thickness. An internal thread is provided on the inner wall of the cylinder of the base shell 411, and an external thread is provided on the outer wall of the pressure plate 412. The pressure plate 412 is threadedly assembled to the base shell 411, and the pressure plate 412 contacts the sliding friction plate 440 to generate damping.

[0058] Since the cap 412 can rotate spirally relative to the base shell 411, the cap 412 can generate displacement along the first direction when it rotates spirally, thereby changing the magnitude of the elastic force on the elastic element 430. That is, the elastic force of the elastic element 430 can be adjusted by the cap 412, thereby adjusting the magnitude of the damping.

[0059] Combination Figure 5A , Figure 5B As shown, the damping module 40 of this application also includes a fixed friction plate 450. The fixed friction plate 450 is located between the bottom plate of the base shell 411 and the elastic element 430. The fixed friction plate 450 is circumferentially fixedly assembled to the base shell 411, so the fixed friction plate 450 cannot rotate. The fixed friction plate 450 directly contacts the elastic element 430, which can prevent wear on the bottom plate of the base shell 411.

[0060] In one specific embodiment, combined with Figure 5AAs shown, the inner wall of the base shell 411 is provided with a first limiting groove 4111, and two or more first limiting grooves 4111 are provided; the fixed friction plate 450 is a disc structure with a central opening, and the central opening of the fixed friction plate 450 avoids the damping shaft 420. The outer edge of the fixed friction plate 450 is provided with a first limiting block 451 protruding from it, and the number of first limiting blocks 451 and first limiting grooves 4111 are equal and correspond one-to-one. The first limiting blocks 451 and first limiting grooves 4111 are slidably inserted along the first direction and are circumferentially limited around the rotation axis, that is, the fixed friction plate 450 is slidably inserted into the base shell 411 along the first direction, and the fixed friction plate 450 and the base shell 4111 are prevented from rotating relative to each other by the cooperation of the first limiting blocks 451 and first limiting grooves 4111.

[0061] Combination Figure 5A As shown, the outer surface of the damping shaft 420 is provided with a second limiting groove 421, and two or more second limiting grooves 421 are provided; the sliding friction plate 440 is a disc structure with a central opening, and the central opening of the sliding friction plate 440 avoids the damping shaft 420. A second limiting block 441 is provided protruding from the inner edge of the sliding friction plate 440, and the number of second limiting blocks 441 and second limiting grooves 421 are equal and correspond one-to-one. The second limiting blocks 441 and the second limiting grooves 421 are slidably inserted along the first direction and are circumferentially limited around the rotating shaft. The sliding friction plate 440 is slidably inserted into the damping shaft 420 along the first direction, and the relative rotation of the sliding friction plate 440 and the damping shaft 420 is prevented by the cooperation of the second limiting blocks 441 and the second limiting grooves 421.

[0062] Combination Figure 3A , Figure 3B As shown, the light carpet module 20 of this application includes a light carpet housing 210, a light diffuser 220, a single convex lens 230, a fixed distance sleeve 240, a double convex lens 250, a light source distance sleeve 260, a light guide column assembly 270, a PCB mounting base 280, an LED PCB assembly 290, and a back cover 2010.

[0063] The light carpet housing 210 and the back cover 2010 are assembled together to form a space for accommodating other structures. A light diffuser 220 is installed at the projection window of the light carpet housing 210. The LED PCB assembly 290 provides a surface light source. After being diffused by the light guide assembly 270, the light is evenly emitted on the end face away from the LED, and the light is evenly distributed by the light guide assembly 270. A single convex lens 230 and a double convex lens 250 image the end face of the light guide away from the LED onto the ground, forming a light carpet pattern, such as... Figure 5B As shown, the distance between the biconvex lens 250 and the PCB mounting base 280 is limited by the light source distance sleeve 260, and the distance between the uniconvex lens 230 and the biconvex lens 250 is limited by the fixed distance sleeve 240. The light passes through the biconvex lens 250 and the uniconvex lens 230 in sequence, and is projected to the outside from the light diffuser 220.

[0064] Specifically, the front and rear surfaces of the monoconvex lens 230 and the biconvex lens 250 are both aspherical, combined with Figure 3B As shown, the two front surfaces of the biconvex lens 250 have different curvatures, while the rear surface of the uniconvex lens 230 facing the biconvex lens 250 is curved. The materials used for both the uniconvex lens 230 and the biconvex lens 250 are PMMA (Polymethyl Methacrylate).

[0065] This application also provides a vehicle that includes the aforementioned dynamic light carpet device, which can achieve the technical effects described above.

[0066] The vehicle controller controls the operation of the drive module 30 based on the car key distance signal, car key button signal, smart device distance signal, smart device control signal, and voice command, thereby driving the light carpet module 20 to rotate.

[0067] Car keys (such as push-button keys or digital keys with control modules) and smart devices (such as mobile phones or watches) can actively send signals to the vehicle controller (such as unlocking the vehicle) to control the opening and closing of the light carpet. When the car key or smart device has a distance sensing module, the vehicle controller can control the opening and closing of the light carpet based on the distance between the car key / smart device and the light carpet. For example, the light carpet can be opened when the distance is less than a preset value and closed when it is greater than a preset value. Alternatively, other preset conditions can be used to control the opening and closing of the light carpet, such as when the driver gets into the car and closes the door, or through voice command control.

[0068] When the driver approaches the vehicle with the car key, the controller receives a signal (external commands such as vehicle command input, voice input, automatic input, and manual input). The controller then controls the motor 310 to rotate. After being decelerated by the gearbox 320, the output shaft 330 splines drive the light carpet module 20 to rotate toward the ground, thus allowing the light carpet to move dynamically. The damping module 40 can eliminate structural gaps and the problem of the light carpet not being able to hover, making the light carpet device less prone to shaking.

[0069] After the vehicle door is closed, the controller receives a signal (from external commands such as vehicle command input, voice input, automatic input, or manual input). The controller then controls the motor 310 to rotate, and the output shaft of the gearbox 320 drives the light carpet module 20 to retract upwards. This prevents the projection window lens of the light carpet module 20 from being covered by dust and dirt while the vehicle is in motion.

[0070] The above description of the disclosed embodiments enables those skilled in the art to make or use the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
