This invention relates to a vehicle warning device and particularly to a vehicle warning device of high security and high convenience.
Thanks to the advancement of technology and the development of vehicles, the distance between urban and rural areas has been much shortened; however, it is followed by increasing traffic accidents every year. From the statistics of the traffic accidents having happened over the years, it is apparent that the traffic accidents were often caused by poor visibility, poor road conditions, quite high driving speed, not maintaining a safe distance and the like, which relatively consumes a lot of social resources and costs; the reason is mainly drivers' inattention or poor visibility. Generally, there is a 70% probability of traffic accidents occurring at night, which accounts for the major cause of all traffic accidents. Visibility is even worse in the rain and thus safety requirements are more stringent on rainy days.
Further, based on road traffic safety rules, if it is not possible to continue driving a running vehicle due to an unpredictable factor, a fault signal light as a warning to rear running cars should be firstly enabled and then a fault sign should be placed behind the car out of order. However, whether it is on general roads, highways, or freeways, especially during daytime, due to the fault signal light or fault sign not being obvious, resulting in the rear car not being able to easily detect the accident ahead, therefore the vehicle out of order would easily get rear-ended by rear vehicles.
A conventional fault sign is formed with only a triangle warning rack and a base; when placed on the road, the height of the sign is close to the road. In the daytime, most drivers do not turn on the lights, so the reflective effect cannot be achieved. Thus, the problem of poor visibility is produced. Further, the risk of accidents happening is caused probably by poor visibility due to poor climate, or by rear vehicle drivers paying little attention to the warning signs on the ground.
In addition, comparing with a conventional light bulbs, a LED has absolute advantages, such as a smaller size, longer service life, lower voltage/current driving, not easily broken, mercury-free, good luminous efficiency, and energy saving. Therefore, the LED is applied very widely in daily life and industries; for example, it is widely applied for various indoor lighting devices, display backlight module, automobile brake light, outdoor information billboard, traffic signs and the like. However, the role of the LED being applied as a light source has been subjected to high expectations and significantly improved, so related energy-saving lamps have gradually emerged and replaced conventional lighting devices.
Thus, the problem of how to breakthrough and resolve the types of defect problems above of conventional fault signs, thereby improving its safety, convenience and economic benefits, as well as combining LED for a more efficient application, is a key focus point which manufacturers and intellectuals should be earnestly trying to resolve and overcome.
Consequently, because of the technical defects described above, the applicant, based on many years of research and experience in the relevant industry has developed the present invention, which may effectively improve the defects described above.
The object of this invention is to provide a vehicle warning device that may emit light by itself to warn other vehicle drivers or pedestrians, thereby having high security.
The object of this invention is further to provide a vehicle warning device that may be placed at a random site outside a vehicle, thereby having high convenience.
In order to achieve the objects mentioned above, the vehicle warning device according to this invention comprises a lamp holder and a charging base. One side of the lamp holder is formed with a plurality of light-emitting diodes (LEDs), while the other side of the lamp holder is formed with a retaining member. Further, the lamp holder comprises a power switch, a power supply unit, and a first electric connection unit. The power switch is disposed outside the lamp holder and electrically connected to the LEDs. The power supply unit is disposed in the lamp holder and electrically connected to the power switch. The first electric connection unit is formed in the lamp holder and electrically connected to the power supply unit. The charging base is provided with a charging unit and a second electric connection unit. The charging unit is electrically connected to the second electric connection unit, while the second electric connection unit is electrically connected to the first electric connection unit.
Now, the present invention will be described more specifically with reference to the following embodiments. It is to be noted that the following descriptions of preferred embodiments of this invention are presented herein for purpose of illustration and description only; it is not intended to be exhaustive or to be limited to the precise form disclosed.
Known from the prior art mentioned above, most fault signs are provided with a reflective design. Thus, when vehicles do not turn on their lights during the day, the faults sign is not able to reflect and warn rear vehicles, or during heavy fog or rain resulting from poor weather and drivers cannot clearly see the fault sign, both situations could cause danger to the parked vehicle. Accordingly, the vehicle warning device is designed for high security and high convenience.

Further, the charging base 20 is provided with a charging unit 22 and a second electric connection unit 24. The charging unit 22 is electrically connected to the second electric connection unit 24, while the second electric connection unit 24 is electrically connected to the first electric connection unit 106. The charging unit 22 may be a plug and supply wire and thus through the charging unit 22 that is connected to a power source, not shown, such as a power outlet of a car, the power supply unit 104 of the lamp holder 10 is charged. However, in the embodiment, the lamp holder 10 is illustrated as a triangle, while the charging base 20 is illustrated as an L-shaped base. The charging base 20 may be provided only for charging the lamp holder 10. The lamp holder 10 and the charging base 20 are not limited to a particular shape. Further, the charging base 20 may be loaded with the lamp holder 10 to facilitate charging the lamp holder 10.
Generally, when the vehicle warning device 1 is not used, the lamp holder 10 may be put aside in a vehicle and the first electric connection unit 106 is made to connect to the second electric connection unit 24 of the charging base 20, thereby allowing the power supply unit 104 to store power. For using the vehicle warning device 1, the first electric connection unit 106 may be detached from the second electric connection unit 24, and then the retaining member 14 is used to mount the lamp holder 10 onto a random site outside the vehicle. For example, when a vehicle malfunctions on a general road or a highway, the retaining member 14, which may be two support stands and is arranged at one side of the lamp holder 10, is vertical to the lamp holder 10 for making the lamp holder 10 stand, as shown in
However, known from the prior art mentioned above, most fault signs are provided with the reflective design. Thus, when rear vehicles do not turn on their lights during the day and is not able to reflect the sign, or during heavy fog or rain resulting from poor weather and drivers cannot clearly see the fault sign, both situations could cause danger to the parked vehicle of being rear-ended. In this invention that solves the defects mentioned above, the LEDs 12 on the lamp holder 10 may emit light by itself to warn the rear vehicle drivers, thus enhancing the warning effect and thereby being featured with high security. And compared with a conventional light bulb, the LED 12 consumes less energy, allowing the lamp holder 10 to emit warning lights for a longer period of time. Further, the lamp holder 10, when being used, may be set in the vehicle or at a random site outside the vehicle to facilitate user operation; the lamp holder 10, when not being used, may be placed in the vehicle and connected to the charging base 20 to charge the power supply unit 104 with power for next time operation, thereby being featured with high convenience.
