Description

Technical Field

[0001] The present invention relates to the technical field of automobile lighting, in particular to a through-lamp assembly for warning vehicles. Background Art

[0002] New energy vehicles (NEVs) use unconventional fuels as their power source (or use conventional fuels with new onboard power units) and incorporate advanced technologies in vehicle power control and drive to create vehicles with advanced technical principles, new technologies, and new structures. New energy vehicles include pure electric vehicles, extended-range electric vehicles, hybrid vehicles, fuel cell electric vehicles, and hydrogen engine vehicles.

[0003] At present, some new energy warning vehicles are equipped with through-lights. The main structures of the through-lights include lampshades, LED light strips, light guide strips (referred to as diffusers in this application), connecting shells, etc. The light guide strips can be used to make the light emitted by the LED light strips more uniform, but because the light guide strips are easily affected by light and turn yellow when used for a long time, it is known that when the lighting conditions are good, such as during the day, the light emitted by the LED light strips needs to ensure a high light intensity, and the light guide strips will cause the light emitted by the LED light strips to weaken. However, at night, the LED light strips must be evenly distributed by the light guide strips to prevent glare. Therefore, this field urgently needs a through-light assembly that can use light guide strips to even out light to improve the light intensity of the LED light strips during the day, but needs to use light guide strips to even out light at night. Summary of the Invention

[0004] The object of the present invention is to provide a through-lamp assembly for warning vehicles to solve the problems raised in the above background technology.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A through-lamp assembly for a warning vehicle, comprising:

[0007] A connecting shell and a lampshade mounted in cooperation with the connecting shell;

[0008] an LED light strip installed in the inner cavity of the connecting shell;

[0009] A flip bracket rotatably connected to the inner cavity of the connecting shell, wherein the connecting shell is provided with a flip mechanism for driving the flip bracket to flip toward the inner side of the connecting shell;

[0010] A diffusion plate is mounted on the flip bracket. When the diffusion plate is flipped to be parallel to the surface of the LED light strip, the diffusion plate is located between the lampshade and the LED light strip.

[0011] Furthermore, the flipping mechanism includes a sliding block inserted into a receiving groove opened on the surface of the connecting shell, and the sliding block slides freely in the receiving groove. A rack portion is opened on the surface of the sliding block, and a gear portion is opened on the surface of the flipping bracket. The gear portion is coaxial with the rotation fulcrum of the flipping bracket on the connecting shell, and the gear portion and the rack portion are externally engaged. A translation component for driving the sliding block to move linearly in the receiving groove is provided in the connecting shell.

[0012] Furthermore, the translation assembly includes a connecting pin fixedly connected to the surface of the sliding block, and a magnetic slider is fixedly connected to the end of the connecting pin away from the sliding block. A waist-shaped hole is provided inside the connecting shell for the connecting pin to pass freely, and an installation cavity is also provided inside the connecting shell for the magnetic slider to pass freely. An electromagnet is installed at the bottom of the installation cavity. The electromagnet is used in conjunction with the magnetic slider, and an elastic member is provided between the two. The elastic member is used to generate an elastic push-up force on the magnetic slider away from the electromagnet.

[0013] Furthermore, the elastic member is a spring, and both ends of the spring in the direction of elastic force elastically press against the electromagnet and the magnetic conductive slider respectively.

[0014] Furthermore, a receiving groove for the diffusion plate to pass freely is formed on an inner wall of one side of the inner cavity of the connection shell.

[0015] Furthermore, an outer wall of one side of the flip bracket is provided with an installation groove for interference fit installation of the diffusion plate.

[0016] Furthermore, the flip bracket is provided with a tensioning mechanism for generating tensioning force on the diffuser plate when the diffuser plate is flipped to be parallel to the surface of the LED light strip.

[0017] Furthermore, the tensioning mechanism includes two clamping arms, which are respectively located at the two ends of the diffuser plate in the length direction. A slot for inserting the end of the clamping arm is provided on the surface of the flip bracket, and a clamping groove for interference fit with the diffuser plate is provided on the side wall of the clamping arm. A clamping component is provided on the connecting shell for generating a clamping force on the clamping arm when the flip bracket is flipped.

[0018] Furthermore, the tightening assembly includes a short pin fixed to one end of the clamping arm that passes through the slot, the short pin passes through the flip bracket and slides freely, a tension spring is wrapped around the periphery of the short pin, and the two ends of the tension spring are respectively fixed to the surface of the clamping arm and the inner wall of the slot, a rubber block is embedded in the outer wall of the connecting shell, and the rubber block is provided with an inclined surface at one end facing the lampshade, and the end of the short pin that passes through the flip bracket is used in conjunction with the inclined surface.

[0019] Furthermore, a ball is rotatably embedded in one end of the short pin extending out of the flip bracket, and the ball is in rolling contact with the inclined surface and the outer wall of the rubber block on one side facing the flip bracket.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. In the present invention, the flip mechanism is set up so that during the day, the diffusion plate is driven to flip, so that the light emitted by the LED light strip does not need to pass through the diffusion plate for uniformity, thereby increasing the light intensity of the LED light strip and facilitating good recognition during the day. At night, the flip mechanism drives the diffusion plate to flip to a state parallel to the LED light strip, so that the diffusion plate can evenly distribute the light emitted by the LED light strip, avoiding glare at night.

[0022] 2. In the present invention, the electromagnet generates magnetism and exerts magnetic attraction on the magnetic slider, so that the flip bracket can rotate toward the lampshade, thereby making the diffuser plate and the LED light strip parallel. When the electromagnet is powered off, the elastic potential energy of the elastic member is released, and the flip bracket can be driven to rotate in the opposite direction, so that the surface of the diffuser plate and the surface of the LED light strip are perpendicular. The structure is relatively compact and is easy to control by the vehicle's on-board computer.

[0023] 3. In the present invention, when the flip bracket flips to a state where the diffuser plate and the LED light strip are parallel, the clamping arm has a tendency to move away from the flip bracket, thereby enabling the clamping arm to generate tension on the diffuser plate, thereby preventing the diffuser plate from vibrating when driving on bumpy roads, thereby affecting the uniformity of light on the LED light strip.

DETAILED DESCRIPTION

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0037] See also Figures 1-11The present invention provides a technical solution: a through-lamp assembly for a warning vehicle, comprising a connecting shell 2 detachably connected to the body structure of a new energy warning vehicle and a lampshade 1 installed in cooperation with the connecting shell 2, an LED light strip 3 is installed in the inner cavity of the connecting shell 2 by means of screws, and a flip bracket 4 is connected to one side wall of the inner cavity of the connecting shell 2 by pivoting, the length direction of the flip bracket 4 is consistent with the length direction of the LED light strip 3, a mounting groove 18 is provided on one side outer wall of the flip bracket 4, a diffusion plate 5 is installed in the mounting groove 18 with an interference fit, the diffusion plate 5 is used to uniformly distribute the light emitted by the LED light strip 3, and the length direction of the diffusion plate 5 is consistent with the length direction of the LED light strip 3, when the flip bracket 4 is flipped so that the diffusion plate 5 is parallel to the surface of the LED light strip 3, the diffusion plate 5 is located between the lampshade 1 and the LED light strip 3, so that when the LED light strip 3 is working, the diffusion plate 5 can uniformly distribute the light emitted by the LED light strip 3;

[0038] A receiving groove is provided on the surface of the connecting housing 2, and a sliding block 6 is slidably engaged and installed in the receiving groove. A rack portion (not marked in the figure) is provided on the surface of the sliding block 6 facing the flip bracket 4. A gear portion 12 is provided on the surface of the flip bracket 4. The gear portion 12 is coaxial with the rotation fulcrum of the flip bracket 4 on the connecting housing 2, and the gear portion 12 and the rack portion are externally meshed. When the sliding block 6 slides in the receiving groove, the gear portion 12 and the rack portion are meshed and transmitted, thereby driving the flip bracket 4 to rotate along the rotation fulcrum with the connecting housing 2;

[0039] A connecting pin is fixedly connected to the surface of the sliding block 6, and the axial direction of the connecting pin is perpendicular to the direction in which the sliding block 6 slides in the accommodating groove. A magnetic slider 8 (i.e., made of any material among iron, cobalt, and nickel) is fixedly connected to the end of the connecting pin away from the sliding block 6. A waist-shaped hole 11 is provided inside the connecting shell 2 for the free passage of the connecting pin, and a mounting cavity 7 is also provided inside the connecting shell 2 for the free passage of the magnetic slider 8. An electromagnet 10 is installed at the bottom of the mounting cavity 7. The electromagnet 10 is used in conjunction with the magnetic slider 8, and an elastic member 9 is provided between the two. The elastic member 9 is used to generate an elastic pushing force on the magnetic slider 8 in the direction away from the electromagnet 10. Specifically, the elastic member 9 is a spring, and the two ends of the spring elastic force direction elastically push against the electromagnet 10 and the magnetic slider 8 respectively. When the electromagnet 10 is energized, magnetism is generated, which in turn pushes the magnetic slider 8. The slider 8 generates a magnetic attraction force, causing the magnetic slider 8 to move toward the direction of the electromagnet 10 and compressing the spring, so that the spring accumulates elastic potential energy. Then, when the electromagnet 10 is powered off, the magnetic attraction force of the electromagnet 10 on the magnetic slider 8 disappears, and the elastic potential energy of the spring is released, thereby driving the magnetic slider 8 to move in the direction away from the electromagnet 10. As a result, when the magnetic slider 8 moves, the connecting pin can drive the sliding block 6 to slide in the receiving groove of the connecting shell 2. In addition, such an arrangement makes the structure more compact. When the sliding block 6 slides in the receiving groove, the gear portion 12 and the rack portion are engaged, thereby driving the flip bracket 4 to flip, so that the diffuser plate 5 can flip. In addition, an inner wall on one side of the inner cavity of the connecting shell 2 (adjacent to the flip bracket 4) is provided with a receiving groove for the diffuser plate 5 to pass freely.

[0040] Slots 14 are provided on the outer walls on both sides of the length direction of the flip bracket 4, and a clamping arm 13 is installed in each of the two slots 14. The two clamping arms 13 are respectively located at both ends of the length direction of the diffuser plate 5. The side walls of the clamping arm 13 are provided with a clamping groove that is interference fit with the diffuser plate 5. One end of the clamping arm 13 that passes through the slot 14 is fixedly connected to a short pin 16. The short pin 16 passes through the flip bracket 4 and slides freely. A tension spring 17 is wrapped around the periphery of the short pin 16. The two ends of the tension spring 17 are respectively fixed to the surface of the clamping arm 13 and the inner wall of the slot 14. A rubber block 19 is embedded in the outer wall of the connecting shell 2. The end of the rubber block 19 facing the lampshade 1 is provided with an inclined surface 20. The end of the short pin 16 that transmits the flip bracket 4 is rotatably embedded with a ball 15. The ball 15 rolls in contact with the inclined surface 20 and the outer wall of the rubber block 19 facing the flip bracket 4.

[0041] When the flip bracket 4 is flipped to the state where the surface of the diffuser plate 5 is parallel to the surface of the LED light strip 3, Figure 8, the short pin 16 will rotate from top to bottom, and make the ball 15 contact the inclined surface 20 on the rubber block 19. Since the rubber block 19 has elastic deformation ability, when the ball 15 rolls from the inclined surface 20 to the surface of the rubber block 19 facing the flip bracket 4, the ball 15 is subjected to a certain extrusion force, and the clamping arm 13 has a tendency to slide toward the outside of the flip bracket 4, thereby making the clamping arm 13 generate tension on the diffuser plate 5, thereby preventing the diffuser plate 5 from vibrating when driving on bumpy roads.

[0042] Working principle of the present invention:

[0043] When driving at night, the driving computer of the new energy warning vehicle controls the power supply of the vehicle to supply power to the electromagnet 10, so that a magnetic attraction force is generated on the magnetic slider 8, causing the magnetic slider 8 to move toward the electromagnet 10 and compressing the spring, so that the spring accumulates elastic potential energy. The magnetic slider 8 drives the sliding block 6 to slide in the receiving groove. When the sliding block 6 slides in the receiving groove, the gear portion 12 and the rack portion engage, thereby driving the flip bracket 4 to flip, so that the diffuser plate 5 can flip, and then the diffuser plate 5 flips to be parallel to the surface of the LED light strip 3. At this time, the diffuser plate 5 can evenly distribute the light emitted by the LED light strip 3.

[0044] During the above process, when the flip bracket 4 flips, the short pin 16 rotates from top to bottom, causing the ball 15 to contact the inclined surface 20 on the rubber block 19. Since the rubber block 19 has elastic deformation ability, when the ball 15 rolls from the inclined surface 20 to the surface of the rubber block 19 facing the flip bracket 4, the ball 15 is subjected to a certain squeezing force, causing the clamping arm 13 to have a tendency to slide toward the outside of the flip bracket 4, thereby causing the clamping arm 13 to generate tension on the diffuser plate 5, thereby preventing the diffuser plate 5 from vibrating when driving on bumpy roads.

[0045] When driving during the day, the on-board computer disconnects the power supply to the electromagnet 10. After the magnetic attraction of the electromagnet 10 to the magnetic slider 8 disappears, the elastic potential energy of the spring is released, thereby driving the magnetic slider 8 to move away from the electromagnet 10, causing the diffuser 5 to flip into the storage slot. At this time, the light emitted by the LED light strip 3 is not interfered by the diffuser 5, so its light intensity is greater, thereby improving the recognition when driving during the day;

[0046] Furthermore, through-lights in this embodiment are installed on the front and sides of the vehicle. These lights change according to vehicle speed, and can indicate the number of vehicles changing lanes, as well as pedestrians or oncoming vehicles through the changing lights. Specifically, sensors are installed on the vehicle body to detect vehicle speed changes. The data collected by the sensors is transmitted to the onboard computer, which controls the LED light strips 3 in the through-lights to change their lighting. For example, at high speeds, the LED light strips 3 illuminate from the center to the sides, forming a "flowing light" pattern, or the flashing frequency can be controlled to alert pedestrians or oncoming vehicles. Automatic settings can also be made based on maps or relevant geographic locations. For example, when a vehicle approaches a threshold distance near a school, the warning function will automatically activate. However, on normal roads, the lighting feedback effect corresponding to a specific speed can be set according to the internal settings. Furthermore, the automatic activation of the warning function can also be set based on factors such as weather and natural light intensity. Furthermore, the location and number of through-lights can be flexibly and randomly adjusted.
