Description

Technical Field

[0001] The present invention relates to the technical field of automotive lighting, and particularly to a warning vehicle through lamp assembly. Background Art

[0002] New energy vehicles refer to vehicles that use unconventional vehicle fuels as the power source (or use conventional vehicle fuels and adopt new in-vehicle power devices), and integrate advanced technologies in the power control and drive aspects of the vehicle to form vehicles with advanced technical principles, new technologies, and new structures. New energy vehicles include pure electric vehicles, range-extended electric vehicles, hybrid vehicles, fuel cell electric vehicles, hydrogen engine vehicles, etc.

[0003] At present, some new energy warning vehicles are equipped with through lamps. The main structures of the through lamps include a lamp cover, an LED light strip, a light guide bar (referred to as a diffusion plate in this application), a connection housing, etc. The light guide bar can be used to make the light emitted by the LED light strip more uniform. However, due to the light guide bar being affected by light during long-term use, it is prone to yellowing. As is well known, in good lighting conditions, such as during the day, the light emitted by the LED light strip needs to ensure a large illumination intensity, and the light guide bar will cause the light emitted by the LED light strip to weaken. However, at night, the LED light strip must use the light guide bar to evenly distribute the light to prevent glare. Therefore, there is an urgent need in the art for a through lamp assembly that can improve the illumination intensity of the LED light strip without using a light guide bar to evenly distribute the light during the day, and needs to use a light guide bar to evenly distribute the light at night. Summary of the Invention

[0004] The purpose of the present invention is to provide a warning vehicle through lamp assembly to solve the problems raised in the above background art.

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

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

[0007] A connection housing and a lamp cover cooperatively installed with the connection housing;

[0008] An LED light strip installed in the inner cavity of the connection housing;

[0009] A flip bracket rotatably connected to the inner cavity of the connection housing, and a flip mechanism for driving the flip bracket to flip towards the inner side of the connection housing is provided in the connection housing;

[0010] A diffusion plate installed 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 lamp cover and the LED light strip.

[0011] Furthermore, the flipping mechanism includes a sliding block inserted into a receiving groove formed on the surface of the connection housing. The sliding block can freely slide within the receiving groove. A rack portion is formed on the surface of the sliding block, and a gear portion is formed on the surface of the flipping bracket. The gear portion is coaxial with the rotation pivot of the flipping bracket on the connection housing, and the gear portion and the rack portion are in external meshing. A translation assembly is provided inside the connection housing for driving the sliding block to linearly move within the receiving groove.

[0012] Furthermore, the translation assembly includes a connection pin fixed to the surface of the sliding block. A magnetic conductive slider is fixed to the end of the connection pin away from the sliding block. An oblong hole is formed inside the connection housing for the connection pin to freely pass through, and an installation cavity is also formed inside the connection housing for the magnetic conductive slider to freely pass through. An electromagnet is installed at the bottom of the installation cavity. The electromagnet is used in cooperation with the magnetic conductive slider, and an elastic member is provided between them. The elastic member is used to generate an elastic abutting force on the magnetic conductive slider in a direction away from the electromagnet.

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

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

[0015] Furthermore, an installation groove for the interference fit installation of the diffusion plate is formed on the outer wall of one side of the flipping bracket.

[0016] Furthermore, a tensioning mechanism is provided on the flipping bracket for generating a tensioning force on the diffusion plate during the process of the diffusion plate flipping to be parallel to the surface of the LED light strip.

[0017] Furthermore, the tensioning mechanism includes two clamping arms. The two clamping arms are respectively located at both ends in the length direction of the diffusion plate. Slots for the ends of the clamping arms to be inserted are formed on the surface of the flipping bracket. Clamping grooves for the interference fit with the diffusion plate are formed on the side walls of the clamping arms. A pressing component is provided on the connection housing for generating a pressing force on the clamping arms when the flipping bracket flips.

[0018] Furthermore, the pressing component includes a short pin fixed to the end of the clamping arm inserted into the slot. The short pin passes through the flipping bracket and can freely slide. A tension spring is wound around the periphery of the short pin. 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 on the outer wall of the connection housing. An inclined surface is provided at the end of the rubber block facing the lampshade. The end of the short pin passing through the flipping bracket is used in cooperation with the inclined surface.

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

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] 1. In the present invention, through the arrangement of the flipping mechanism, during the day, the driving diffusion plate is flipped so that the light emitted by the LED light strip does not need to be homogenized by the diffusion plate, thereby increasing the light intensity of the LED light strip and facilitating good recognition during the day. At night, the flipping mechanism drives the diffusion plate to flip to a state parallel to the LED light strip, enabling the diffusion plate to homogenize the light emitted by the LED light strip and avoiding glare at night.

[0022] 2. In the present invention, the electromagnet generates magnetism and exerts a magnetic attraction force on the magnetic conductive slider, enabling the flipping bracket to rotate towards the direction of the lamp cover, and then making the diffusion plate parallel to the LED light strip. When the electromagnet is powered off, the elastic potential energy of the elastic member is released and can drive the flipping bracket to rotate in the reverse direction, making the surface of the diffusion plate perpendicular to the surface of the LED light strip. The structure is relatively compact and convenient for the vehicle's on-board computer to control.

[0023] 3. In the present invention, during the process of the flipping bracket flipping to a state where the diffusion plate is parallel to the LED light strip, the clamping arm has a tendency to move away from the flipping bracket, thereby enabling the clamping arm to generate a tension force on the diffusion plate and preventing the diffusion plate from vibrating when driving on a bumpy road surface, which may otherwise affect the homogenization of the light of the LED light strip.

Specific embodiments

[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0037] Please refer to Figures 1 - 11, the present invention provides a technical solution: a warning vehicle through lamp assembly, including a connection housing 2 detachably connected to the body structure of a new energy warning vehicle and a lamp cover 1 cooperatively installed with the connection housing 2. An LED light strip 3 is installed in the inner cavity of the connection housing 2 by means of screws. One side wall of the inner cavity of the connection housing 2 is rotatably connected to a flipping bracket 4 through a pivot. The length direction of the flipping bracket 4 is the same as the length direction of the LED light strip 3. An installation groove 18 is formed on the outer wall of one side of the flipping bracket 4. A diffusion plate 5 is installed in the installation groove 18 by interference fit. The diffusion plate 5 is used to make the light emitted by the LED light strip 3 uniform. In addition, the length direction of the diffusion plate 5 is the same as the length direction of the LED light strip 3. When the flipping bracket 4 is flipped until the diffusion plate 5 is parallel to the surface of the LED light strip 3, the diffusion plate 5 is located between the lamp cover 1 and the LED light strip 3. In this way, when the LED light strip 3 is working, the diffusion plate 5 can make the light emitted by the LED light strip 3 uniform;

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

[0039] A connecting pin is fixedly connected to the surface of the sliding block 6. The axial direction of the connecting pin is perpendicular to the sliding direction of the sliding block 6 in the receiving groove. A magnetic conductive slider 8 (i.e., made of any one of iron, cobalt, and nickel) is fixedly connected to the end of the connecting pin away from the sliding block 6. A kidney-shaped hole 11 for the free passage of the connecting pin is provided inside the connecting housing 2, and an installation cavity 7 for the free passage of the magnetic conductive slider 8 is also provided inside the connecting housing 2. An electromagnet 10 is installed at the bottom of the installation cavity 7. The electromagnet 10 is used in cooperation with the magnetic conductive slider 8, and an elastic member 9 is provided between the two. The elastic member 9 is used to generate an elastic abutting force on the magnetic conductive 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 abut against the electromagnet 10 and the magnetic conductive slider 8 respectively. When the electromagnet 10 is energized, it generates magnetism, and then generates a magnetic attraction force on the magnetic conductive slider 8, causing the magnetic conductive slider 8 to move in the direction of the electromagnet 10 and compress the spring, so that the spring accumulates elastic potential energy. Then, when the electromagnet 10 is powered off, after the magnetic attraction force of the electromagnet 10 on the magnetic conductive slider 8 disappears, through the release of the elastic potential energy of the spring, the magnetic conductive slider 8 is driven to move in the direction away from the electromagnet 10, so that when the magnetic conductive slider 8 moves, the sliding block 6 can be driven to slide in the receiving groove of the connecting housing 2 through the connecting pin. In addition, such a setting makes the structure relatively compact. When the sliding block 6 slides in the receiving groove, it will drive the flipping bracket 4 to flip through the meshing of the gear portion 12 and the rack portion, so that the diffusion plate 5 can flip. In addition, a receiving groove for the free passage of the diffusion plate 5 is provided on one inner wall of the inner cavity of the connecting housing 2 (adjacent to the flipping bracket 4);

[0040] Slots 14 are provided on the outer walls on both sides in the length direction of the flipping bracket 4. A clamping arm 13 is inserted and installed in each of the two slots 14. The two clamping arms 13 are respectively located at both ends in the length direction of the diffusion plate 5. A clamping groove that is in interference fit with the diffusion plate 5 is provided on the side wall of the clamping arm 13. A short pin 16 is fixedly connected to the end of the clamping arm 13 that penetrates into the slot 14. The short pin 16 passes through the flipping bracket 4 and slides freely. A tension spring 17 is wound around the periphery of the short pin 16. The two ends of the tension spring 17 are respectively fixedly connected to the surface of the clamping arm 13 and the inner wall of the slot 14. A rubber block 19 is embedded on the outer wall of the connecting housing 2. An inclined surface 20 is provided at the end of the rubber block 19 facing the lamp shade 1. A ball 15 is rotatably embedded at the end of the short pin 16 that passes out of the flipping bracket 4. The ball 15 is in rolling contact with the inclined surface 20 and the outer wall of the rubber block 19 facing the flipping bracket 4;

[0041] During the process of the flipping bracket 4 flipping until the surface of the diffusion plate 5 is parallel to the surface of the LED light strip 3, refer to Figure 8, the short pin 16 will rotate from top to bottom, making the ball 15 contact the surface of the inclined plane 20 on the rubber block 19. Since the rubber block 19 has the ability of elastic deformation, when the ball 15 rolls from the inclined plane 20 to the surface of the rubber block 19 facing the side of the flipping bracket 4, the ball 15 is subjected to a certain extrusion force, making the clamping arm 13 tend to slide outward from the flipping bracket 4, and further making the clamping arm 13 generate a tension force on the diffusion plate 5, avoiding the vibration of the diffusion plate 5 on bumpy roads.

[0042] The working principle of the present invention:

[0043] When driving at night, the power supply of the vehicle supplies power to the electromagnet 10 under the control of the vehicle computer of the new energy warning vehicle, generating a magnetic suction force on the magnetic conductive slider 8, making the magnetic conductive slider 8 move towards the direction of the electromagnet 10 and compressing the spring, so that the spring accumulates elastic potential energy. The magnetic conductive slider 8 drives the sliding block 6 to slide in the receiving groove. When the sliding block 6 slides in the receiving groove, it will drive the flipping bracket 4 to flip through the meshing of the gear part 12 and the rack part, so that the diffusion plate 5 can flip, and further make the diffusion plate 5 flip to be parallel to the surface of the LED light strip 3. At this time, the diffusion plate 5 can homogenize the light emitted by the LED light strip 3;

[0044] During the above process, when the flipping bracket 4 flips, the short pin 16 will rotate from top to bottom, making the ball 15 contact the surface of the inclined plane 20 on the rubber block 19. Since the rubber block 19 has the ability of elastic deformation, when the ball 15 rolls from the inclined plane 20 to the surface of the rubber block 19 facing the side of the flipping bracket 4, the ball 15 is subjected to a certain extrusion force, making the clamping arm 13 tend to slide outward from the flipping bracket 4, and further making the clamping arm 13 generate a tension force on the diffusion plate 5, avoiding the vibration of the diffusion plate 5 on bumpy roads;

[0045] When driving during the day, the vehicle computer disconnects the power supply of the electromagnet 10. After the magnetic suction force of the electromagnet 10 on the magnetic conductive slider 8 disappears, through the release of the elastic potential energy of the spring, the magnetic conductive slider 8 is driven to move away from the electromagnet 10, making the diffusion plate 5 flip into the receiving groove. At this time, since the light emitted by the LED light strip 3 is not interfered by the diffusion plate 5, its light intensity is relatively large, so during the day when driving, the recognition is better;

[0046] Furthermore, the through lights in this embodiment are installed on the front and side of the vehicle. The through lights change continuously according to the change of vehicle speed. The change of lights can be used to prompt the lane-changing vehicle, and can also prompt pedestrians or the following vehicle of the approximate vehicle speed. Specifically, sensors are installed on the vehicle body to collect the change of vehicle speed. The data collected by the sensors is transmitted to the vehicle computer, and the vehicle computer controls the LED light strip 3 in the through lights to produce light changes. For example, when the vehicle speed is relatively high, the lights of the LED light strip 3 light up from the middle to both sides to form a "flowing light", or the flashing frequency of the lights is controlled, so as to be able to prompt pedestrians or the following vehicle. Among them, we can also make automatic settings based on the map or relevant geographical locations. For example, when the vehicle arrives at the threshold distance near the school, the warning function is automatically turned on, while on the normal road surface, the light feedback effect corresponding to the specific speed can be set according to the internal settings; at the same time, the warning function can also be set to be automatically turned on according to factors such as weather and natural light intensity. In addition, the installation position and number of the through lights can also be adjusted flexibly and randomly.
