Description

Electronic angle regulator

Technical field

The utility model relates to a kind of electronic angle regulator, it make Reflector mounted thereto, monitoring device or other executive device realize within the specific limits about, about the adjustment of four different directions angles, with the required spatial dimension of deriving means.

Background technology

Back mirror is installed in the both sides of car, is to observe the automobile accessories parts of front vehicle, pedestrian's situation in the process of moving for chaufeur, and be the assurance of guaranteeing safe driving.In order to make chaufeur that bigger possible visual-field space is arranged when driving, automobile rearview mirror generally all has the manual regulation function, be between mirror holder and the fixed support and fixed support and vehicle body between all be that the joint sexuality is connected, can make mirror holder drive Reflector travel direction adjustment within the specific limits together.But have only the back mirror of manual regulation function to use inconvenience, chaufeur has to stop or get off and adjust sometimes, only needs to carry out the adjustment of minute angle sometimes, but is difficult to accurate control with hand.Therefore, the automobile that has has begun to install electronic angle regulator on back mirror.This type of electronic angle regulator mainly is made up of base, active ring (supporting plate), rotation support, motor and worm gear, worm gearing at present, two motors are fixed on the base at an angle, the output of motor by worm and gear drive active ring (supporting plate) about the rotatably supported strong point is done, about the angular adjustment of four different directions, and the Reflector of back mirror is directly installed on the active ring (supporting plate), has so just realized the angular adjustment of back mirror Reflector.Because worm couple takes up room greatly, therefore make taking up room of whole electronic angle regulator also big, inconvenience is installed, so its application (the especially application on little back mirror) is subjected to certain restriction.

The utility model content

The purpose of this utility model provides and a kind ofly takes up room for a short time, quick and easy for installation, and it is reliable to operate steadily, the electronic angle regulator that usage range is wider.

For this reason, electronic angle regulator described in the utility model, comprise body, base, active ring, rotational support and motor, wherein base is installed on the body, one end of base stretches in the circular groove of active ring, the contact surface that cooperatively interacts on base and the active ring is a sphere, two of rotational support is fixed on the active ring, its middle part is hinged on from the extended back-up block of base inner bottom part, and the back-up block end is stretched in the position-limited trough of rotational support, two motors are fixed on the base by bracing frame and are symmetrically located at the both sides of back-up block, the output shaft of motor links to each other with planetary reduction gear, the inwall axial restraint of active ring has tooth bar, and the mouth of planetary reduction gear is fixed with gear, the wheel and rack engagement.

The button of control machine operation can be arranged on the work top of operator's compartment in the utility model, the Reflector of back mirror can directly fasten on the end face that is installed in active ring, when chaufeur need carry out small adjustment to the range of observation of back mirror, can press the button, actuating motor, after the output of motor is slowed down through planetary reduction gear, the gear that drive is fixed on the planetary reduction gear rotates, this gear drives the tooth bar that is fixed on the active ring inwall again and produces displacement, because active ring is hinged on from the extended back-up block of base inner bottom part by rotational support, and rotational support can only ridden the rotation that the strong point on the back-up block is done opposite both direction, two motor cooperatings are about the Reflector that just can make active ring drive back mirror is made, about the adjustment of four different directions angles.

The beneficial effects of the utility model are: whole apparatus structure is simple, it is little, easy to install to take up room, and it is reliable to operate steadily, and field of application is more extensive.
