Description

Technical Field

[0001] The utility model relates to the technical field of vehicles, in particular to a photoelectric anti-pinch device for a passenger door of a bus. Background Art

[0002] Currently, all passenger door anti-pinch devices in the bus industry are contact-type. They require the passenger door to contact the human body when closing, generating a reaction force. This signal is then detected by the onboard controller, which then stops the door from closing or immediately opens it to prevent pinching. However, the peak clamping force during door closing can briefly exceed 150N, potentially causing discomfort or slight pain at the clamping site, impacting passenger comfort and safety.

[0003] Based on the above reasons, this design proposes a photoelectric anti-pinch device for passenger doors of buses. Summary of the Invention

[0004] The purpose of the utility model is to provide a photoelectric anti-pinch device for a passenger door of a bus.

[0005] To achieve the above-mentioned purpose, the utility model is implemented through such a technical solution, a photoelectric anti-pinch device for a passenger door of a bus, comprising: a reflective infrared photoelectric switch, arranged at the transmitting end and the transmitting end of the door, for detecting obstructions; a controller module, connected to the photoelectric switch, for receiving the signal of the photoelectric switch and controlling the switch state of the door.

[0006] Furthermore, after the car door is opened, if the transmitting end and the reflecting end of the photoelectric anti-pinch device are blocked by an object or a passenger, the controller module receives a low-level signal from the sensor input. At this time, when the door closing button is pressed, the controller does not output the door closing signal, resulting in the car door not closing. When the obstruction is removed, the sensor signal disappears. Only when the door closing button is pressed can the controller output the door closing signal, allowing the car door to close.

[0007] Furthermore, during the door closing process, if an object or passenger appears between the transmitting end and the reflecting end of the photoelectric anti-pinch device, the controller module receives a low-level signal input by the sensor, the anti-pinch function is triggered, and the controller immediately outputs a door opening signal to the door pump controller module to open the door.

[0008] Furthermore, after the door is closed, the controller module receives a door closing signal and shields the anti-pinch function of the photoelectric anti-pinch device to prevent the door from opening suddenly due to obstructions while the vehicle is driving.

[0009] The beneficial effects of the above scheme are:

[0010] The utility model has the advantages of simple structure, high sensitivity, wide application range, etc., has no influence on the function of the original door controller, and is suitable for wide application in the bus industry. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Figure 1 It is a schematic diagram of the main structure of the utility model.

[0012] In the figure: 1, transmitting end; 2, reflecting end. DETAILED DESCRIPTION

[0013] The present invention will be further described in detail below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited thereto. Example

[0014] like Figure 1 As shown, a photoelectric anti-pinch device for a passenger door of a bus includes: a reflective infrared photoelectric switch, which is arranged at the transmitting end 1 and the transmitting end 2 of the door and is used to detect obstructions; a controller module, which is connected to the photoelectric switch and is used to receive signals from the photoelectric switch and control the opening and closing state of the door.

[0015] In this embodiment, after the car door is opened, if the transmitting end 1 and the reflecting end 2 of the photoelectric anti-pinch device are blocked by an object or a passenger, the controller module receives a low-level signal input by the sensor. At this time, the door closing button is pressed, and the controller does not output the door closing signal, resulting in the car door not closing. When the obstruction is removed, the sensor signal disappears, and the controller can output the door closing signal by pressing the door closing button, so that the car door can be closed.

[0016] In this embodiment, during the door closing process, if an object or passenger appears between the transmitting end 1 and the reflecting end 2 of the photoelectric anti-pinch device, the controller module receives a low-level signal input by the sensor, the anti-pinch function is triggered, and the controller immediately outputs a door opening signal to the door pump controller module to open the door.

[0017] In this embodiment, after the vehicle door is closed, the controller module receives a door closing signal and shields the anti-pinch function of the photoelectric anti-pinch device to prevent the vehicle door from opening suddenly due to obstructions while the vehicle is driving.

[0018] Working principle:

[0019] A reflective infrared photoelectric switch is used as an anti-pinch sensor. Its working principle is as follows:

[0020] When there is an object blocking the transmission end 1 and the reflection end 2 of the photoelectric anti-pinch device, the photoelectric sensor will send an anti-pinch trigger signal.

[0021] The working logic operation realizes the following functions:

[0022] After the car door is opened, if the transmitting end 1 and the reflecting end 2 of the photoelectric anti-pinch device are blocked by an object or a passenger, the controller module will receive a low-level signal input by the sensor. At this time, the controller will not output the door closing signal when the door closing button is pressed, and the car door will not close; when the obstruction is removed, the sensor signal disappears, and the controller will output the door closing signal when the door closing button is pressed, and the car door can be closed.

[0023] During the door closing process, if an object or passenger appears between the transmitting end 1 and the reflecting end 2 of the photoelectric anti-pinch device, the controller module will receive a low-level signal from the sensor input, the anti-pinch function will be triggered, and the door opening signal will be immediately output to the door pump controller module to open the door.

[0024] After the door is closed, the controller module receives the door closing signal and shields the anti-pinch function of the photoelectric anti-pinch device to prevent the door from opening suddenly due to obstructions while the vehicle is driving.

[0025] The embodiments disclosed in the present invention are preferred embodiments, but are not limited to them. Ordinary technicians in this field can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. As long as they do not deviate from the spirit of the present invention, they are all within the scope of protection of the present invention.
