Embodiment Construction

[0014] Please refer to figure 1 , figure 1 It is a control principle block diagram of the rearview mirror folder control system in a preferred embodiment of the present invention. figure 1 The control module of the middle rearview mirror folder control system includes a motor 10 and two control modules 20, 21 connected to the motor. rotation and reverse rotation; each control module includes a current conduction module 201, a current cutoff module 202 and a sampling module 203, and the input current is input to the motor 10 through the current conduction module 201 so that the motor rotates to drive the rearview mirror to rotate to After the abutting part, the rearview mirror rotates to the abutting part, and the sampling module 203 samples the circuit voltage and makes the current cut-off module 202 work to cut off the current input to the motor 10 so that the motor stops rotating.

[0015] In this embodiment, after the rearview mirror is rotated in place, that is, after it...

Abstract

The invention provides a control system of a rearview mirror folder. The control system comprises a rearview mirror, an abutting portion and a control device. The control device comprises a motor and two control modules which are connected to the motor. A forward input current and a backward input current are connected to the two control modules respectively for enabling the motor to rotate forwards and backwards. Each control module comprises a current conduction module, a current cut-off module and a sampling module. The input currents are input to the motor through the current conduction modules to enable the motor to rotate, accordingly, the rearview mirror is driven to rotate to the abutting portion, the sampling modules are used for sampling circuit voltage after the rearview mirror rotates to the abutting portion, the current cut-off modules are made to operate to cut off the currents input to the motor, and the motor is made to stop rotating.

Description

technical field [0001] The invention relates to the technical field of automobile control, in particular to a rearview mirror folder control system. Background technique [0002] In the prior art, the rearview mirror of the automobile is used for the driver to observe the vehicles behind, but the rearview mirrors are installed on both sides of the automobile. To make the rearview mirror collide with other vehicles and pedestrians, the driver can only fold the rearview mirror. [0003] Existing rearview mirror folding devices, such as the Chinese patent "Automobile Rearview Mirror Folding Device" with publication number CN202656933U, include a fixing device, a transmission mechanism, a motor and a rotating mechanism. The motor, the transmission mechanism and the rotating mechanism are all installed on the fixing device. The rotating mechanism includes a central column, an elastic element, and the elastic element is sleeved on the central column. And compress the elastic ele...
