Description

Technical Field

[0001] This invention relates to the field of transportation vehicles, and more particularly to a pedal-type door closing mechanism. Background Technology

[0002] Currently, in some transportation sectors, the door handles are located far from the driver and passengers, making it very inconvenient for them to enter and exit. To achieve a comfortable closing action, the opening angle is often reduced. Therefore, it is necessary to install a closing mechanism to improve the convenience of entry and exit for drivers and passengers while ensuring a suitable opening angle without compromising closing comfort.

[0003] Most existing pedal-type door closing mechanisms are controlled by a foot pedal, with a cable wound around a rotating shaft. When the pedal is pressed, the cable is pulled, which in turn drives the rotating shaft to rotate. Gears are installed on the rotating shaft and the door. When the rotating shaft rotates, the two gears on the door and the rotating shaft mesh with each other, thereby driving the door to rotate and achieve the closing action. When the door is opened, the gear on the door drives the gear on the rotating shaft to rotate, which in turn drives the rotating shaft to rotate, and the cable is wound around the rotating shaft.

[0004] Therefore, a simple door closing mechanism is needed that can ensure the door opening angle while also ensuring the comfort of the driver and passengers when opening the door. Summary of the Invention

[0005] This application provides a pedal-type door closing mechanism, which is lower in cost than the prior art and solves the technical problem that it is inconvenient for drivers and passengers to close the door when the distance between them and the door handle is far. It achieves the technical effect of increasing the door opening angle without reducing the comfort of closing the door, thereby improving the convenience of drivers and passengers to enter and exit.

[0006] This application provides a pedal-type door closing mechanism, including a pedal assembly, a transmission assembly, a lubrication assembly, a cleaning assembly, and a rotation assembly;

[0007] The pedal assembly includes a pedal base, a pedal, a fixed pulley, a spring, and a thin plate;

[0008] The pedal base and the foot pedal are rotatably connected, and the spring is fixedly connected to both sides of the pedal base and the foot pedal.

[0009] The pedal consists of a pedal bracket and a foot pedal, which are fixedly connected and have a certain angle.

[0010] The fixed pulley is located in front of the foot pedal and is used to change the direction of the rope force;

[0011] The thin plate is located below the elastic airbag and on the pedal base. When lubrication is needed, the thin plate is pulled out. The front end of the thin plate near the elastic airbag has rounded corners to prevent scratching the elastic airbag during the movement of the thin plate.

[0012] The transmission assembly includes a fixed pulley, a movable pulley, a cable, and a pulley housing. The cable is divided into a first section and a second section. The first section connects the fixed pulley and the movable pulley, and the second section connects the movable pulley and the rotating shaft. The pulley housing is divided into a movable pulley housing and a fixed pulley housing. The movable pulley and the fixed pulley are respectively fixed inside the movable pulley housing and the fixed pulley housing, which protect the pulleys. The movable pulley housing is fixed to the guide rail by a bracket, and the fixed pulley housing is fixed by a bracket.

[0013] The lubrication assembly includes an oil reservoir, a cylinder assembly, an oil delivery hose, a check valve, and a throttle valve. The cylinder assembly includes a cylinder body, a spring, a piston, and a nozzle assembly.

[0014] The oil storage tank and the cylinder are connected by an oil delivery hose, with a one-way valve installed in between to prevent oil from flowing back from the cylinder to the oil storage tank.

[0015] The oil cylinder and the nozzle are connected by an oil delivery hose. There is a one-way valve and a throttle valve on the oil delivery hose. The function of the one-way valve is to prevent oil backflow. The oil output is adjusted by adjusting the throttle valve.

[0016] The cleaning assembly includes an elastic airbag assembly and an air delivery hose;

[0017] The elastic airbag assembly is located below the foot pedal and includes an airbag body, a spring, and a pressure block; the spring is located inside the elastic airbag, and the pressure block is located above the elastic airbag.

[0018] The nozzle assembly includes a nozzle and a resilient cap. The nozzle has an air supply hose and an oil supply hose connected to it simultaneously, but they are not connected to each other. There is a resilient cap at the oil outlet. When lubrication is required, the resilient cap will open under the pressure inside the oil supply hose. When lubrication stops, the resilient cap will block the oil outlet to prevent oil leakage.

[0019] The rotating assembly includes a rotating shaft, gear one, gear two, and a door panel;

[0020] The first gear is fixed on the rotating shaft and the second gear is fixed on the door panel. When the pedal is stepped on, the cable drives the rotating shaft to rotate, the rotating shaft drives the first gear to rotate, and the first gear drives the second gear to achieve the door closing action.

[0021] When the door is opened, gear two drives gear one to rotate, gear one drives gear two to rotate, and gear two drives the rotating shaft to rotate, and the cable is wound onto the rotating shaft;

[0022] The door closing latch assembly includes a door closing latch and a bolt;

[0023] The door closing latch and the door closing pin work together. The door closing latch is fixed to the upper side of the door panel, and the door closing pin is fixed to the door frame, corresponding to the position of the door closing latch. When closing the door, the door closing latch will lock the door closing pin to prevent the door from opening accidentally after closing. When opening the door, push the door first to disengage the door closing latch and the door closing pin, thereby opening the door.

[0024] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0025] By installing an elastic airbag assembly and a lubrication assembly on the foot pedal of the existing pedal-type door closing mechanism, the pressure generated when the foot pedal is pressed squeezes the elastic airbag and the lubrication assembly. Gas and lubricating oil are then delivered to the two meshing gears on the rotating shaft through oil and gas hoses. This effectively solves the problem in the existing technology where the two meshing gears are prone to wear during long-term door opening and closing, affecting the door opening and closing effect. As a result, the technical effect of lubrication and cleaning is achieved at the same time as opening and closing the door. Attached Figure Description

However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to enable a more thorough and complete understanding of the disclosure of the present invention.

[0047] It should be noted that the terms "vertical," "horizontal," "up," "down," "left," "right," and similar expressions used in this article are for illustrative purposes only and do not represent the only possible implementation.

[0048] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to limit the invention; the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0049] Please see Figure 4 This is a schematic diagram of the overall structure of a pedal-type door closing mechanism according to the present invention.
