Description

Technical Field

[0001] This utility model relates to a passenger door fault diagnosis tool, belonging to the technical field of passenger door fault diagnosis for buses. Background Technology

[0002] As the main passageway for passengers to board and alight, the proper functioning of passenger doors is crucial for passenger safety, convenience, and the overall operational efficiency of the bus. Passenger doors contain multiple components, such as solenoid valves, anti-pinch switches, and emergency valves, which work together to ensure their proper operation. A malfunction in any of these components can significantly impact the passenger experience and even safety. For example, controlling the on / off state of the solenoid valve coil reverses the airflow, thus opening and closing the passenger door. If the solenoid valve malfunctions, the passenger door will not open or close automatically.

[0003] Currently, when passenger doors malfunction on buses, only simple alarms can be displayed on the instrument panel, such as passenger door opening or emergency valve opening. The instrument panel display is too general (e.g., is the passenger door opening due to a solenoid valve malfunction or a corresponding controller malfunction?), only indicating the result and not specifying which component is faulty. In the current market, troubleshooting passenger door malfunctions generally requires an electrician using a multimeter, relying on the vehicle's wiring and power supply. This is susceptible to interference from the vehicle's wiring and power supply, making it difficult to quickly pinpoint the faulty component, and also requires a high level of electrical expertise from the operators.

[0018] Figure 1 This is a schematic diagram of the structure of this utility model. Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments.

[0020] The concept of this utility model is that different connectors are customized according to the test interface reserved in the plug-in of the bus passenger door. These connectors are connected to the indicator device. After the customized connector is plugged into the test interface reserved in the plug-in of the passenger door, the power is turned on, and the status of the indicator device is used to determine whether the corresponding passenger door plug-in is faulty.

[0021] Tool Example:

[0022] This embodiment provides a passenger door troubleshooting tool. Passenger doors on buses are mainly divided into inward-swinging doors and outward-swinging doors, and each bus has an emergency valve that can open the passenger door in an emergency. The main components of an inward-swinging door include a pneumatic anti-pinch switch, a solenoid valve, a magnetic anti-pinch switch, and an anti-pinch controller; the main components of an outward-swinging door include an air pump solenoid valve, a door light connector (door light switch), an anti-pinch connector (anti-pinch switch), and a Hall effect sensor; the main connectors of the emergency valve connector include an emergency valve alarm connector and an emergency valve door opening signal connector. Among them, both pneumatic anti-pinch switches and magnetic anti-pinch switches are used to monitor whether the passenger door is pinching an object during the closing process, but their working principles are different; both solenoid valves and door pump solenoid valves receive signals from the controller to realize the opening and closing of the inward swing door and the outward swing door; the anti-pinch controller receives various signals during the passenger door closing process to determine whether passengers are pinching an object. Once an object is detected, it immediately sends a corresponding signal to stop the passenger door from closing or even open it in reverse. It can also control the passenger door to close by receiving a closing signal; the door light plug is a component installed on the door for lighting. When the passenger door is opened or closed, the door light will turn on or off. The anti-pinch plug is used to monitor whether an object is caught in the passenger door during the closing process; the Hall sensor is used to detect the status of the passenger door. For example, when the passenger door is fully closed, it sends a corresponding control signal to the corresponding controller, thereby causing the controller to disable the anti-pinch plug; the emergency valve alarm connector is used to detect whether the emergency valve is opened. For example, the cover outside the emergency valve knob; when the cover is opened, the bus instrument panel will display that the emergency valve is open and issue a warning; the emergency valve opening signal connector is used to detect whether the emergency valve is in use. For example, the emergency valve knob; when the emergency valve knob is turned to a certain position, an opening signal is immediately sent to make the passenger door open immediately.

[0023] First, different connectors were developed according to the reserved test interface types of these passenger door plugs (components). These connectors are used to connect the reserved test interfaces of each passenger door plug. The positive and negative terminals of each connector are connected to the positive and negative terminals of the power module through connecting lines. An indicator device (e.g., status light) and a switch are connected in series on the connecting lines. The indicator device is used to issue an indication when the connection port is plugged into the corresponding test interface and the circuit of the corresponding component under test is connected or disconnected, so as to determine whether the corresponding component under test is normal.

[0024] Specifically, to facilitate quick troubleshooting of passenger door components using this tool, different connection ports and power modules (control power supplies) are provided according to the type of passenger door components. These connection ports can be detachable or connected via wires. For example... Figure 1As shown, the connection ports include an inner swing door port (inner swing door interface), an outer swing door port (outer swing door interface), and a general port (general interface). The positive and negative terminals of the inner swing door port are connected to the positive and negative terminals of the power module via a power supply line. A first indicating device and a first switch are connected in series on this power supply line. The positive and negative terminals of the inner swing door port are connected to the connectors of the inner swing door via a test harness. These connectors are connected in parallel and then connected to the inner swing door port via the test harness. The connectors of the inner swing door include a first inner swing door connector for inserting a test interface reserved for the pneumatic anti-pinch switch of the inner swing door, a second inner swing door connector for inserting a test interface reserved for the solenoid valve of the inner swing door, a third inner swing door connector for inserting a test interface reserved for the magnetic anti-pinch switch of the inner swing door, and a fourth inner swing door connector for inserting a test interface reserved for the anti-pinch controller of the inner swing door.

[0025] Furthermore, since the opening coil and closing coil of the solenoid valve plug for the inward-swinging door are integrated, one of the positive and negative terminals of the second inward-swinging door connector includes an opening coil terminal and a closing coil terminal. These terminals are used to connect to the non-common terminals of the solenoid valve opening coil test interface and the inward-swinging door solenoid valve closing coil test interface, respectively. A first single-pole double-throw switch is installed on the corresponding lines of the branches containing the opening and closing coil terminals of the second inward-swinging door connector on the inward-swinging door test harness, allowing selective connection of the opening and closing coil terminals. The other positive and negative terminal of the second inward-swinging door connector is used to connect to the common terminal of the solenoid valve opening and closing coil test interfaces of the inward-swinging door.

[0026] Because the anti-pinch controller outputs a door light signal upon receiving an open or close signal, the fourth inward-swinging door connector includes a positive terminal, a negative terminal, and an output door light signal terminal. The negative terminal of the fourth inward-swinging door connector is used to connect to the common terminal of the anti-pinch controller's test interface. The output door light signal terminal of the fourth inward-swinging door connector is used to connect to the door light signal test terminal in the pre-reserved test interface of the anti-pinch controller. The output door light signal terminal is connected in series with the fourth indicating device and then connected to the negative line of the test harness that connects the fourth inward-swinging door connector to the connection port. The positive terminals of the fourth inward-swinging door connector include an open signal terminal and a close signal terminal. The open signal terminal and the close signal terminal are respectively used to connect to the non-common interface of the anti-pinch controller's test interface for receiving open signals and for receiving close signals. Furthermore, a second single-pole double-throw switch is installed on the corresponding lines of the branches containing the open signal terminal and the close signal terminal of the fourth inward-swinging door connector on the inward-swinging door test harness, allowing selective connection of the open signal terminal and the close signal terminal.

[0027] The positive and negative terminals of the outward-swinging door port are connected to the positive and negative terminals of the power module via a power supply line. A second indicating device and a second switch are connected in series on this power supply line. The positive and negative terminals of the outward-swinging door port are connected to the connectors of the outward-swinging door via a test harness. These connectors are connected in parallel and then connected to the outward-swinging door port via the test harness. The connectors of the outward-swinging door include a first outward-swinging door connector with a reserved test interface for connecting the door pump solenoid valve of the outward-swinging door; a second outward-swinging door connector with reserved test interfaces for connecting the door light and anti-pinch switch of the outward-swinging door; and a third outward-swinging door connector with a reserved test interface for connecting the Hall sensor of the outward-swinging door.

[0028] Furthermore, since the door light and anti-pinch switch of the outward-swinging door are integrated, one of the positive and negative terminals of the second outward-swinging door connector includes a door light terminal and an anti-pinch switch terminal. The door light terminal and the anti-pinch switch terminal are respectively used to connect to the non-common terminal of the door light test interface and the non-common terminal of the anti-pinch switch test interface of the outward-swinging door. A third single-pole double-throw switch is provided on the corresponding line of the branch where the door light terminal and the anti-pinch switch terminal of the second outward-swinging door connector are located on the outward-swinging door test harness, thereby allowing selective connection of the door light terminal and the anti-pinch switch terminal. The other positive and negative terminal of the second inward-swinging door connector is used to connect to the common terminal of the door light and anti-pinch switch test interface of the outward-swinging door.

[0029] The positive and negative terminals of the general-purpose port are connected to the positive and negative terminals of the power module via a power supply line. An indicator device and a fourth single-pole double-throw switch are connected in series on this power supply line. The positive and negative terminals of the outward-swinging door port are connected to the test interface reserved for the emergency valve alarm (which sends an alarm signal when the emergency valve is opened) and the test interface reserved for the emergency valve (which sends an opening signal when the emergency valve is turned to the correct position) via a test harness and test probes. These connectors are connected in parallel and then connected to the outward-swinging door port via the test harness. The purpose of the fourth single-pole double-throw switch is to switch between two states: 1) The positive and negative terminals of the power module are connected to the positive and negative terminals of the general-purpose port respectively, so as to use the power module to test the emergency valve alarm, the emergency valve, and the circuits or electrical appliances targeted by the test probes connected to the positive and negative terminals of the test harness respectively; 2) The positive and negative terminals of the general-purpose port are short-circuited to use the test probes to test the vehicle's power supply and related circuits.

[0030] The following example, using status lights as indicators, and some specific fault symptoms, illustrates the working principle of this troubleshooting tool:

[0031] Inward swing door port: Power off the entire vehicle. After connecting the first inward swing door connector to the test interface reserved for the pneumatic anti-pinch switch, close the first switch. Since the pneumatic anti-pinch switch is normally open when the passenger door is not closed, it will become closed if a fault occurs. Therefore, if the first indicator light is constantly on when the passenger door is not closed, the pneumatic anti-pinch switch is faulty. After connecting the second inward swing door connector to the test interface reserved for the solenoid valve, close the first switch. The first indicator light will illuminate. Repeatedly toggle the first single-pole double-throw switch to different positions to energize the opening or closing coil of the solenoid valve. If the solenoid valve does not engage (which can be determined by sound), the solenoid valve coil is faulty. After connecting the third inward swing door connector to the test interface reserved for the magnetic anti-pinch switch, close the first switch. When the magnetic anti-pinch switch is normal and the passenger door is closed, it is normally closed. If a fault occurs, it will become normally open. Therefore, if the first indicator light is not on when the passenger door is manually closed, the magnetic anti-pinch switch is faulty. Since the anti-pinch controller receives door opening and closing signals from the pneumatic and magnetic anti-pinch switches and controls whether the solenoid valve is engaged, it should only be tested when the pneumatic, solenoid valve, and magnetic anti-pinch switches are all functioning normally. Otherwise, if a fault is detected in the anti-pinch controller, it cannot be determined whether the fault lies with the controller itself, the pneumatic, solenoid valve, or magnetic anti-pinch switch. After connecting the fourth inward swing door connector to the test interface reserved in the anti-pinch controller, close the first switch. Any of the following situations indicate a fault in the anti-pinch controller: the first indicator is not lit, the fourth indicator is not lit, and the solenoid valve does not engage after repeatedly toggling the second single-pole double-throw switch to different positions.

[0032] Outward-swinging door port: Vehicle power off. After connecting the first outward-swinging door connector to the reserved test interface of the door pump solenoid valve's opening or closing coil, close the second switch. If the second indicator light illuminates but the door pump solenoid valve does not engage, the door pump solenoid valve is faulty. Connect the second outward-swinging door connector to the reserved test interface of the door pump door light plug-in (door light). Under normal conditions, the door pump door light plug-in is normally open after the passenger door is closed. Therefore, set the third single-pole double-throw switch to be connected to the door light switch. If the second indicator light remains illuminated after the passenger door is closed, the door light switch is faulty. Connect the second outward-swinging door connector to the reserved test interface of the door pump anti-pinch plug-in (anti-pinch switch). Under normal conditions, the anti-pinch plug-in is normally open during the passenger door closing process. Therefore, set the third single-pole double-throw switch to be connected to the anti-pinch switch. If the second indicator light remains illuminated during the passenger door closing process, the anti-pinch switch is faulty. Connect the third outward swing door connector to the test interface reserved by the Hall sensor. If the status lights of the second indicator device and the Hall sensor itself do not light up after the passenger door is closed, then the Hall sensor is faulty.

[0033] General Port: Vehicle power off. After connecting the first emergency connector to the test interface reserved on the emergency valve alarm, switch the fourth single-pole double-throw switch to connect to the control power supply. If the third indicator light illuminates when the emergency valve alarm is not open, the emergency valve alarm connector is faulty. After connecting the second emergency connector to the test interface reserved on the emergency valve, switch the fourth single-pole double-throw switch to connect to the control power supply. If the emergency valve is not turned to its proper position, the third indicator light illuminates, indicating an emergency valve fault. For inward and outward swing door inserts from different manufacturers, use a test probe (multimeter probe) to directly connect to the test interface holes reserved on each component of the passenger door, and then perform measurements. The corresponding functions and principles are as described above.

[0034] The test probe can also detect the liveness of the vehicle's power supply and the vehicle's wiring harness: after connecting the multimeter probe to the corresponding wiring harness, switch the third switch to the position where it is disconnected from the control power supply, then power on the vehicle and observe the status of the third indicator device. If it lights up, the wiring harness and the vehicle's power supply are normal.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail with reference to the above embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the specific implementation of this utility model.
