MULTIFUNCTIONAL REARVIEW MIRROR

Abstract

A multifunctional rearview mirror includes a casing having first and second receiving spaces. A mirror is mounted to one side of the casing that is formed with the first receiving space. The second receiving space is located under the first receiving space and has a front surface formed with first through-holes. A distance detection and alarm unit is arranged in the second receiving space and includes an ultrasonic distance detection module, an alarm light module, and a buzzer. The ultrasonic distance detection module is eclectically connected with the alarm light module and the buzzer. The alarm light module is arranged in the first through-holes. The ultrasonic distance detection module emits an ultrasonic wave, which is returned to the ultrasonic distance detection module by an object, so that a distance to the object is calculated and the alarm light module and the buzzer are activated according to the distance.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0010] Referring to FIGS. 1 and 2, the present invention provides a multifunctional rearview mirror, which comprises:

[0011] at least one rearview mirror body 10, which comprises a casing 11 and at least one mirror body 12, wherein the casing 11 includes a first receiving space (not shown) that is in communication with the outside and a second receiving space (not shown) that is a closed space; the mirror body 12 is rotatably mounted one side of the casing 11 that is formed with the first receiving space; the second receiving space is located under the first receiving space; the second receiving space has a front surface that is formed with a plurality of first through-holes 111 and a second through-hole 112 that is adjacent to the first through-holes 111; and the casing 11 has an outside surface that is formed with a recess 113 and a cover 114 that is light transmitting is provided to cover and close the recess 113.

[0012] Referring to FIGS. 1-3, a distance detection and alarm unit 20 is arranged and mounted in the second receiving space and comprises at least one ultrasonic distance detection module 21, an alarm light module 22, and a buzzer 23, the ultrasonic distance detection module 21 being electrically connected to the alarm light module 22 and the buzzer 23.

[0013] The ultrasonic distance detection module 21 comprises a transmitter 211 and a receiver 212.

[0014] The alarm light module 22 comprises a first light-emitting element 221, a second light-emitting element 222, a third light-emitting element 223, and a fourth light-emitting element 224. The first light-emitting element 221, the second light-emitting element 222, and the third light-emitting element 223 are each set in a respective one of the first through-holes, and the fourth light-emitting element 224 and the buzzer 23 are arranged and mounted in the recess 113.

[0015] A driving recorder comprises at least one lens 31 and a storage unit (not shown). The lens 31 is set to correspond to the second through-hole 112.

[0016] Referring to FIGS. 3 and 4, the transmitter of the ultrasonic distance detection module 21 transmits and emits an ultrasonic wave. The ultrasonic wave, when colliding and contacting an object, is returned and the receiver 212 of the ultrasonic distance detection module 21 detects and receives the returned ultrasonic wave, and also calculate a distance relative to the object, and activates the first light-emitting element 221, the second light-emitting element 222, or the third light-emitting element 223, and the buzzer 23 according to the distance.

[0017] When the distance detected by the ultrasonic distance detection module 21 is one meter, two meters, or three meters, the first light-emitting element 221, the second light-emitting element 222, or the third light-emitting element 223 are correspondingly activated to give off light, and based on the distance of the automobile relative to the object, an alarm sound issued by the buzzer 23 is getting faster and of higher frequency when the distance is getting shorter.

[0018] Further, in a practical application, the ultrasonic distance detection module 21 may be arranged to electrically connect with a steering unit (not shown) of the automobile. The steering unit comprises a turn signal lever (not shown), and when a driver pushes the turn signal lever, the ultrasonic distance detection module 21 is activated to emit the ultrasonic wave, and the fourth light-emitting element 224 is also activated.
