Description

Technical Field

[0001] The invention relates to the field of automobile warning devices, in particular to an automobile rear danger warning device. Background Art

[0002] In Chinese patent CN94222830.8, a car rear-end collision prevention safety warning device is proposed, which is composed of a colored lampshade and a light-emitting element, a control circuit, and a bottom plate. Its plane shape is the same as the warning sign in the traffic rules - the attention danger sign. The triangular side and exclamation mark of the warning sign are composed of the lampshade, and the lampshade is fixed to the bottom plate. The light-emitting element can be connected to the reversing and brake taillights, fault signal lights or night driving taillight circuits separately or simultaneously to emit light synchronously. The bottom plate can be fixed to the rear windshield of the car or the rear of the truck by bonding, suction cups, bolts, etc. It has a simple structure, is easy to disassemble and assemble, and is convenient to use. It has a clear and eye-catching warning effect at any time.

[0003] When a traditional automobile warning device is rear-ended by a vehicle behind during the transportation of dangerous goods, if there is no buffer structure at the rear, it will be affected by the impact force of the rear-end collision and increase the probability of the tank body rupture, which will cause a major accident. Once hit, the lamp body of the automobile warning device will be damaged first, resulting in limited function. Damage to the warning light can easily lead to rear-end collisions by the vehicle behind.

[0004] Therefore, in view of the above problems, a vehicle rear danger warning device is proposed. Summary of the invention

[0005] In order to make up for the shortcomings of the existing technology, the problem of rear-end collision with the rear vehicle occurring during the transportation of dangerous goods by a truck is solved. If no buffer structure is set at the rear end, the tank body will be affected by the impact force occurring during the rear-end collision, thereby increasing the probability of the tank body rupture. Damage to the warning light may easily lead to rear-end collision with the rear vehicle.

[0006] The technical solution adopted by the present invention to solve its technical problems is: a car rear hazard warning device described in the present invention includes a device body, buffer structures are provided on the upper and lower sides of the device body, and a protective structure is provided on the front outer side of the device body, a limit plate passes through the bottom of the device body, and a connecting rod is fixed to the bottom of the limit plate, a button is provided on the inner side of the limit plate, and a driving bearing is provided above the button, and a gear is provided on the outer side of the driving bearing, a tooth plate is installed on the right side of the outer wall of the gear, and a sliding block is provided on the outer wall of the tooth plate, and a vertical plate is provided on the outer side of the sliding block, a warning light strip is installed on the top of the tooth plate, suction cups are provided on both sides of the rear of the device body, and a rear plate is installed in the middle position of the rear of the device body.

[0007] Preferably, a ferrule is installed on the front outer wall of the device body, and a circular light strip passes through the interior of the ferrule, and a main light is installed in the middle position of the circular light strip.

[0036] A connecting block 201 is installed inside the buffer structure 2, and the outer wall of the connecting block 201 is connected to a connecting plate 202, a mounting plate 203 is fixed to the outer wall of the connecting plate 202, and a first mounting screw 204 passes through the inside of the mounting plate 203, the protective structure 3 is fixed to the connecting plate 202, and the connecting block 201 is fixed inside the connecting plate 202. When impacted, the protective structure 3 first slides backward on the outer wall of the device body 1 through the force of the connecting block 201 sliding inward inside the buffer structure 2, and at the same time, the telescopic spring inside the connecting block 201 contracts. When the telescopic spring loses its extrusion force after the collision, it rebounds and drives the connecting block 201 to rebound, and then a part of the protective structure 3 pops outward at the same time, which can effectively buffer the impact force to a certain extent, and effectively extend the service life of the device.

[0037] The buffer structure 2 is slidably connected to the connecting block 201, and is welded to the device body 1. The buffer structure 2 is fixed to the outer wall of the device body 1 to stably support the protective structure 3 and improve the buffering effect of the entire buffer structure 2 against impact force.

[0038] A fixed inner plate 301 is fixed inside the protective structure 3, and a protective net 302 is arranged on the outer side of the fixed inner plate 301, and a movable outer plate 303 is arranged on the outer side of the protective net 302, and second mounting screws 304 are passed through the upper and lower sides of the movable outer plate 303. The movable outer plate 303 can be removed by the second mounting screws 304. The protective net 302 is snap-fitted and fixed inside the protective structure 3 and supported by the fixed inner plate 301, so that the protective net 302 can be easily replaced. The protective net 302 can effectively protect the lamp body without affecting the light emitted by the lamp body, and the replacement is simple.

[0039] The movable outer panel 303 forms a detachable structure with the protective structure 3 through the second mounting screws 304, and the protective structure 3 and the device body 1 are snap-fitted. When the rear end of the car is hit, the protective structure 3 is hit first, and the warning main light 13 and the circular light strip 17 can be protected by the protective structure 3. The protective structure 3 is snap-fitted to the outer wall of the device body 1, which can facilitate the installation and disassembly of the protective structure 3.

[0040] The gear 8 forms a rotating structure with the device body 1 through the driving bearing 7, and the driving bearing 7 is electrically connected to the button 6, and the center point of the button 6 is arranged in the same straight line as the top of the limit plate 5. The connecting rod 4, the limit plate 5, the button 6, the driving bearing 7, the gear 8 and the tooth plate 9 form a lifting structure. When the rear of the car is hit, the protective structure 3 slides inward, driving the limit plate 5 to slide inward synchronously and hit the start button 6, so that the electrically connected driving bearing 7 acts on the gear 8 to rotate to drive the tooth plate 9 to rise. Under the tensile action of the internal electric push rod, the warning light strip 12 can rise to a height of one to one meter and two meters when encountering a car accident, and the flashing light serves as a warning, which can avoid a chain accident caused by a tire blowout and rear-end collision, and can warn the vehicle fifty to one hundred meters away. Under normal conditions, it remains closed and is located inside the device and is not easily damaged.

[0041] The gear 8 is meshedly connected to the tooth plate 9, and the tooth plate 9 forms a sliding structure with the vertical plate 11 through the slider 10. During the lifting process of the tooth plate 9, the slider 10 on the outer wall slides up and down inside the vertical plate 11, which can play a limiting role and improve the stability of the tooth plate 9 when it is lifted and lowered.

[0042] The rear panel 15 is rotationally connected to the device body 1, and the device body 1 is glued to the suction cup 14. The device body 1 is installed and fixed to the rear of the car through the suction cup 14. This installation method does not affect the integrity of the paint surface of the rear of the car. The interior of the device can be inspected by opening the rear panel 15.

[0043] Embodiment 2

[0044] See also Figure 1 , Figure 3 , Figure 4 , Figure 7 as well as Figure 8 As shown, in comparison with Example 1, as another embodiment of the present invention, a ferrule 16 is installed on the front outer wall of the device body 1, and a circular light strip 17 passes through the inside of the ferrule 16, and a main light 13 is installed in the middle position of the circular light strip 17.

[0045] The ring 16 is bonded to the device body 1 with glue, and the ring 16 and the circular light strip 17 are double-layered. The device emits circular light through the double-layer circular light strip 17, and combines with the main light 13 to emit a hazard light prompt, which can improve the hazard warning effect of the device.

[0046] Working principle: First, when the rear of the car is hit, it first hits the protective structure 3, through which the main warning light 13 and the circular light strip 17 can be protected. The protective structure 3 is engaged with the outer wall of the device body 1, which can facilitate the installation and removal of the protective structure 3. The movable outer plate 303 can be removed by the second mounting screw 304. The protective net 302 is engaged and fixed inside the protective structure 3 and supported by the fixed inner plate 301, which makes it easy to replace the protective net 302, and the protective net 302 can effectively protect the lamp body;

[0047] Secondly, the protective structure 3 is fixed to the connecting plate 202 by the action of the mounting plate 203 and the first mounting screw 204, and the connecting block 201 is fixed inside the connecting plate 202. When the protective structure 3 is hit, the connecting block 201 slides inwardly inside the buffer structure 2 to slide backward on the outer wall of the device body 1. At the same time, the telescopic spring inside the connecting block 201 contracts. When the telescopic spring loses its squeezing force after the collision, it will rebound and drive the connecting block 201 to rebound, and then a part of the protective structure 3 will pop outward at the same time, which can effectively buffer the impact force to a certain extent.

[0048] Finally, the connecting rod 4, the limit plate 5, the button 6, the driving bearing 7, the gear 8 and the tooth plate 9 form a lifting structure as a whole. When the rear end of the car is hit, the protective structure 3 slides inward first. Since the connecting plates 202 on both sides of the lower side of the device are welded and fixed in the middle of the connecting rod 4, a limit plate 5 is set on the top of the connecting rod 4, and a groove is reserved at the bottom of the device for the limit plate 5 to slide. The limit plate 5 slides inward synchronously and hits the start button 6, so that the electrically connected driving bearing 7 acts on the gear 8 to rotate to drive the tooth plate 9 to rise. Under the tensile action of the internal electric push rod, the warning light strip 12 can rise to one to one meter when encountering a car accident. The device is designed to be at a height of two, and the flashing light serves as a warning, which can avoid a series of car accidents caused by tire blowouts and rear-end collisions, and can warn the vehicle fifty to one hundred meters behind. Under normal conditions, it remains closed and is located inside the device, which is not easily damaged and consumes less power. During the lifting process of the tooth plate 9, the slider 10 on the outer wall slides up and down inside the vertical plate 11, which can play a limiting role and improve the stability of the tooth plate 9 when it is lifted. The device body 1 is installed and fixed to the rear of the car through a suction cup 14, and the interior of the device can be inspected by opening the rear plate 15. The double-layer ring light strip 17 fixed by the ring 16 emits a ring light, which is combined with the main light 13 to emit a hazard light prompt.
