An electric parking door hinge

Abstract

The invention relates to a door hinge, a new type of electric parking door hinge, comprising a power transmission part, a roller mechanism, a parking mechanism and a hinge part, and the power transmission part has a motor frame, a motor, a coupling, a ball screw nut , Ball screw screw, the coupling includes a hexagonal rod and an inner hexagonal cylinder that are slidingly matched with each other, one end of the hexagonal rod is connected to the motor shaft, the other end is inserted into the inner hexagonal cylinder to form a sliding connection, and the other end of the inner hexagonal cylinder is connected to the ball screw The end of the rod screw; the roller mechanism has a roller connector and a roller, and the other end of the roller connector is connected to the top of the ball screw screw through a gasket I; the parking mechanism has an interconnected trapezoidal slider with a rebound device and a brake Sheet assembly, roller groove, slider groove; the hinge part has a hinge body, a hinge mandrel, and the hinge sheet has a mandrel sleeve; when the roller is pushed between the roller groove and the slider groove, there is a rebound device The inclined surface of the trapezoidal slider drives the brake pads to hold the mandrel sleeve of the hinge piece tightly to realize the door parking.

Description

technical field [0001] The invention relates to a door hinge, in particular to an electric parking door hinge which is driven by a tiny DC motor and can be parked and self-locked at any time. Background technique [0002] In our life, doors are everywhere, but in the process of using the door, sometimes it needs to be slightly opened, sometimes it needs to be half-opened, and sometimes it needs to be fully opened. When it comes to how to locate the door, after the door is opened, if it cannot be positioned to a certain extent, the door will be forced to close due to wind blowing or collision, and sometimes it will cause damage to the door. The current solution on the market is to choose a door suction, but , on the one hand, the door suction is only used for the fully open state of the door, on the other hand, during the installation process of the door suction, it is necessary to punch holes on the door, or on the floor, or on the wall. , this will destroy the integrity an...

[0002] In our life, doors are everywhere, but in the process of using the door, sometimes it needs to be slightly opened, sometimes it needs to be half-opened, and sometimes it needs to be fully opened. As for how to position the door, after the door is opened, if it cannot be positioned properly, the door will be forced to close due to wind or collision, and sometimes the door will be damaged. The current solution on the market is to choose a door stopper, but On the one hand, the door stopper is only used for the fully open state of the door. On the other hand, during the installation process of the door stopper, it is necessary to punch holes on the door, or on the floor, or on the wall. , this will destroy the integrity and affect the appearance. Moreover, if the wall and the ground are all ceramic tiles, it will be difficult to punch holes on it, which will destroy the integrity of the wall or the ground. In addition, the existing parking door However, there are still some defects such as use effect and automation, and the described a kind of electric parking door hinge can solve the problem
