Description

Technical Field

[0001] This utility model relates to a warning light, and more particularly to an embedded flashing warning light for preventing rear-end collisions in electric vehicles. Background Technology

[0002] With the rapid growth of electric vehicles worldwide, traffic safety, especially traffic accidents involving electric vehicles, has become an increasingly serious social problem. Among these, rear-end collisions involving electric vehicles are frequent, which not only threaten the safety of riders but also increase the difficulty of urban traffic management.

[0003] Currently, electric vehicle rear-end collision prevention devices on the market mainly rely on passive reflective materials or simple LED taillights. These traditional rear-end collision prevention measures have obvious shortcomings. Passive reflective materials can only be effective under the illumination of vehicle headlights, and their protective effect is limited at night or in poor lighting conditions. Existing LED taillights usually only light up when braking and do not actively light up to provide a warning during normal driving. They need to be manually turned on by the driver. This method cannot effectively ensure that the following vehicle maintains a safe braking distance from the vehicle in front, especially in dynamically changing traffic environments, which increases the risk of collision.

[0004] Therefore, there is an urgent need for an embedded electric vehicle anti-rear-collision flashing warning light that can monitor the distance of vehicles behind in real time and automatically turn on the warning lights according to the actual situation. Utility Model Content

[0005] To overcome the shortcomings of current electric vehicle LED taillights, which cannot actively provide warnings while driving and require manual operation to activate the warning function, this utility model provides an embedded electric vehicle anti-rear-collision flashing warning light that can monitor the distance of vehicles behind in real time and automatically turn on the warning lights according to the actual situation.

[0006] To address the aforementioned problems, this utility model adopts the following technical solution: an embedded electric vehicle anti-rear-collision flashing warning light, comprising a housing, a mounting structure, a rectangular lamp holder, an LED flashing light assembly, a control panel, a millimeter-wave radar, a signal receiver, a mounting base, an alarm bell, a sleeve, a slide bar, a return spring, an impact block, a magnet, and an iron ball. The housing has a symmetrically distributed mounting structure at the center of its back side. A rectangular lamp holder is located inside the housing, and an LED flashing light assembly is mounted around the rectangular lamp holder. A mounting groove is formed in the center of the rectangular lamp holder, and a millimeter-wave radar is mounted above and inside the mounting groove. A control panel is installed at the bottom inside the mounting slot. A signal receiver is integrated on the control panel. The LED flashlight assembly, control panel, millimeter-wave radar, and signal receiver are electrically connected. A mounting base is fixed to the lower back of the housing. An alarm bell is mounted on the mounting base. A sleeve is provided at the bottom of the housing. A sliding rod is slidably installed inside the sleeve. A return spring is sleeved on the sliding rod. The two ends of the return spring are connected to the sliding rod and the sleeve, respectively. An impact block is provided at the end of the sliding rod near the alarm bell. A magnet is fixedly installed on the inner wall of the sleeve. An iron ball is placed inside the sleeve.

[0007] Furthermore, it also includes mounting blocks, with symmetrically distributed mounting blocks on both sides of the outer casing.

[0008] Furthermore, each of the mounting structures includes a mounting base, a clamp, a screw, and a knob. The mounting base is fixed to the back of the housing, the mounting base is provided with a clamp, the opening of the clamp is threaded with a screw, and the top of the screw is threaded with a knob.

[0009] Furthermore, it also includes a hinge and a cover plate, with a hinge provided on the top of the housing and a cover plate hinged to the hinge.

[0010] Furthermore, the cover plate is designed to be transparent.

[0011] Furthermore, it also includes a locking block, a push rod, a rotating shaft, a limiting hook block, and a torsion spring. The locking block is fixedly connected to the lower side of the cover plate. The bottom of the outer shell has symmetrically distributed guide grooves. Push rods are slidably arranged on the lower parts of both sides of the outer shell. One end of the push rod extends into the inner shell and is located inside the guide groove, while the other end extends out of the outer shell. The bottom of the inner shell has symmetrically distributed rotating shafts fixedly installed. A limiting hook block is rotatably arranged on the rotating shaft. The limiting hook block contacts and cooperates with the locking block. A torsion spring is sleeved on the rotating shaft. The two ends of the torsion spring are connected to the limiting hook block and the rotating shaft, respectively.

[0012] Furthermore, the limiting hook block is provided with a bevel at a certain angle, and the two sides of the locking block are also designed with bevels.

[0013] Furthermore, it also includes a sealing strip, which is embedded in the front side of the housing and is in close contact with the cover plate.

[0014] Compared with the prior art, this utility model has the following technical effects: 1. By monitoring the distance changes of vehicles behind in real time through millimeter-wave radar, and combining the control panel and signal receiver, the LED flashing lights automatically turn on and enter flashing mode when the detection distance is lower than the preset safety threshold. This can effectively remind drivers behind to maintain a safe distance and significantly reduce the risk of rear-end collisions caused by excessive distance. In addition, through the combined design of alarm bell, sleeve, slide bar, return spring, impact block, magnet and iron ball, this device can also issue an audible alarm when a minor collision occurs. This design can not only promptly notify riders and surrounding people of potential dangers, but also improve on-site safety.

[0015] 2. The installation structure, consisting of a mounting base, clamps, screws, and knobs, allows for quick and easy installation and removal of the warning lights, while ensuring the stability and reliability of the installation.

[0016] 3. The cover plate protects the internal components from the influence of the external environment. At the same time, the design of the locking block, push rod, rotating shaft, limit hook block and torsion spring ensures that the cover plate will not be opened accidentally during use, increasing the stability and reliability of the equipment.

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0025] Example 1: Please refer to Figures 1-5An embedded electric vehicle rear-end collision prevention flashing warning light includes a housing 1, mounting blocks 101, a rectangular lamp holder 8, an LED flashing light assembly 9, a control panel 10, a millimeter-wave radar 1001, a signal receiver 11, a mounting base 12, an alarm bell 13, a sleeve 14, a slide bar 15, a return spring 16, an impact block 17, a magnet 18, and an iron ball 19. The housing 1 has a symmetrically distributed mounting structure on the back center, and mounting blocks 101 are symmetrically distributed on both sides of the housing 1. The mounting blocks 101 provide additional fixing points for the warning light, making installation easier and more stable when embedded into the rear cover of the electric vehicle. The housing 1 contains a rectangular lamp holder 8, and an LED flashing light assembly 9 is mounted around the rectangular lamp holder 8. The LED flashing light assembly 9 can produce high-brightness, dynamically changing light warnings, effectively increasing the attention of following vehicles and reducing the occurrence of rear-end collisions. The rectangular lamp holder 8 has a mounting groove in the middle, and a millimeter-wave radar is mounted above the mounting groove. The radar 1001 has a control panel 10 installed at the bottom of the mounting slot. A signal receiver 11 is integrated on the control panel 10. The LED flash group 9, control panel 10, millimeter-wave radar 1001, and signal receiver 11 are electrically connected to achieve distance measurement data acquisition and processing. A fixing base 12 is fixedly connected to the lower back of the housing 1. An alarm bell 13 is provided on the fixing base 12 to emit an alarm sound when a collision occurs. A sleeve 14 is provided at the bottom of the housing 1. A sliding rod 15 is slidably provided inside the sleeve 14. A return spring 16 is sleeved on the sliding rod 15. The two ends of the return spring 16 are respectively connected to the sliding rod 15 and the sleeve 14. An impact block 17 is provided at the end of the sliding rod 15 near the alarm bell 13 to strike the alarm bell 13 and emit a sound. A magnet 18 is fixedly installed on the inner wall of the sleeve 14. An iron ball 19 is placed inside the sleeve 14. The iron ball 19 can roll along the inside of the sleeve 14 and roll in contact with the sliding rod 15.

[0026] When using the electric vehicle anti-rear-collision flashing warning light, firstly, depending on the type of electric vehicle, the warning light is embedded and installed on the rear cover, or hung on the rear tailpipe through the mounting structure. During actual driving or parking, the millimeter-wave radar 1001 monitors the distance changes between vehicles behind, and the control panel 10 receives the distance information measured by the millimeter-wave radar 1001 through the signal receiver 11. When the detected distance is lower than the preset safety threshold, the control panel 10 will activate the LED flashing light group 9 to flash in a specific mode to remind vehicles behind to maintain a safe distance, thereby preventing rear-end collisions. If a minor collision occurs, the iron ball 19 will overcome the attraction of the magnet 18 and move backward under the impact and inertia, hitting the slide bar 15 and compressing the return spring 16, causing the slide bar 15 to drive the impact block 17 to strike the alarm bell 13, producing a clear alarm sound to promptly notify the driver and surrounding personnel of potential danger so that appropriate measures can be taken. Once the impact of the collision is eliminated, the iron ball 19 will be attracted back to the initial position by the magnet 18, waiting for the next use.

[0027] Example 2: Based on Example 1, please refer to... Figure 2 Each of the mounting structures includes a mounting base 4, a clamp 5, a screw 6, and a knob 7. The mounting base 4 is fixed to the back of the outer casing 1. The mounting base 4 is provided with a clamp 5. The opening of the clamp 5 is threaded with a screw 6. The top of the screw 6 is threaded with a knob 7.

[0028] When installing the warning light, first, turn knob 7 to loosen screw 6, then remove screw 6 from the opening of clamp 5, leaving clamp 5 in the open position. Next, use the open clamp 5 to engage the rear tailpipe of the electric vehicle, ensuring the warning light is hung in the desired position. Finally, screw the previously removed screw 6 back into the opening of clamp 5, adjust it to the appropriate position, and then screw knob 7 into the top of screw 6 until knob 7 and screw 6 are fully locked, ensuring clamp 5 firmly grips the rear tailpipe, completing the entire installation process. This design allows for quick and convenient installation and removal of the warning light, while ensuring the stability and reliability of the installation. It allows users to flexibly adjust the position of the warning light according to actual needs, thus improving ease of use.

[0029] Please see Figure 1 and Figure 3It also includes a hinge 2, a cover plate 3, and a sealing strip 25. The top of the housing 1 is provided with a hinge 2, and the cover plate 3 is hinged to the hinge 2. The cover plate 3 covers the front side of the housing 1 to protect the internal components. The cover plate 3 adopts a transparent design, which, while ensuring the protective function of the cover plate 3, also allows the light of the LED flash light group 9 to be emitted through the cover plate 3, ensuring that it can effectively play a warning role under any circumstances. The front side of the housing 1 is provided with a sealing strip 25, which is in close contact with the cover plate 3 to increase the sealing between the housing 1 and the cover plate 3, effectively preventing moisture and dust from entering the interior of the housing 1.

[0030] Please see Figure 3 , Figure 5 and Figure 6 It also includes a locking block 20, a push rod 21, a rotating shaft 22, a limiting hook 23, and a torsion spring 24. The locking block 20 is fixedly connected to the lower side of the cover plate 3. A guide groove symmetrically distributed on the left and right sides is provided at the bottom inside the outer shell 1. Push rods 21 are slidably arranged on the lower parts of both the left and right sides of the outer shell 1. One end of the push rod 21 extends into the interior of the outer shell 1 and is located inside the guide groove, while the other end extends out of the outer shell 1 for operation. A rotating shaft 22 symmetrically distributed on the left and right sides is fixedly installed at the bottom inside the outer shell 1. A limiting hook 23 is rotatably arranged on the rotating shaft 22. The hook block 23 contacts and engages with the locking block 20. The limiting hook block 23 has a beveled surface at a certain angle. The left and right sides of the locking block 20 also adopt a beveled design. The purpose of this design is to allow the two to smoothly engage or disengage during operation. When the limiting hook block 23 rotates, due to the presence of the beveled surface, the locking block 20 can smoothly engage or disengage from the limiting hook block 23, reducing friction and possible wear, and ensuring smooth operation. A torsion spring 24 is sleeved on the rotating shaft 22. The two ends of the torsion spring 24 are connected to the limiting hook block 23 and the rotating shaft 22, respectively.

[0031] The cover plate 3 is designed to effectively seal the outer shell 1 and protect the internal parts. When it is necessary to open or close the cover plate 3, press the push rod 21 inward. The push rod 21 will push the limit hook block 23 to rotate clockwise around the rotating shaft 22, causing the torsion spring 24 to deform. At this time, due to the inclined surface of the limit hook block 23 and the inclined surface of the locking block 20, it is easy to release or lock the locking block 20, which facilitates the opening or closing of the cover plate 3. After the operation is completed, release the push rod 21. The limit hook block 23 loses its pushing force and rotates counterclockwise to reset under the elastic force of the torsion spring 24. This allows the limit hook block 23 to hook the locking block 20 that is subsequently re-locked, ensuring that the cover plate 3 is securely closed and preventing accidental opening during use.
