Description

Technical Field

[0001] This application relates to the technical field of service contact management, and in particular to a service contact storage device. Background Technology

[0002] During aircraft cleaning / sewage truck operations, the service connector of the water truck needs to be connected and disconnected from the aircraft.

[0003] During the separation operation from the aircraft, if the service connector is not returned to its original position before the vehicle is started, it may connect with the aircraft, causing pulling damage to the aircraft and posing a significant safety hazard. Utility Model Content

[0004] To ensure that the vehicle can only be driven after the service connector is returned to its original position, this application provides a service connector storage device.

[0005] This application provides a service connector storage device, which adopts the following technical solution: A service contact storage device, comprising: Storage box; The controller, connected to the vehicle driving control system, is used to issue commands to start the vehicle or prevent the vehicle from moving; A control switch is installed inside the storage box, and the control switch is electrically connected to the controller. The extrusion plate is rotatably installed inside the storage box. When the service connector is placed inside the storage box, the extrusion plate is driven to extrude the control switch, triggering the controller to send a signal to start the vehicle.

[0006] By adopting the above technical solution, after the operation is completed, the operator puts the service connector into the storage box; during the placement process, the connector contacts the extrusion plate and applies force, causing the extrusion plate to rotate around the rotation point; the rotating extrusion plate presses the control switch, and the control switch transmits an electrical signal to the controller; after receiving the signal, the controller releases the vehicle movement restriction, and the operator can start the vehicle normally; if the connector is not placed, the extrusion plate does not move, the control switch is not triggered, the controller continuously issues a "do not move" command, and the vehicle cannot be started, reducing the safety hazard of the aircraft being pulled and damaged due to the connector not being put back in its original position and the vehicle being started.

[0007] Optionally, a clearance groove is provided through the bottom of the storage box for the water pipe of the service connector to pass through the storage box, and the water pipe and the clearance groove form a snap-fit ​​relationship.

[0008] By adopting the above technical solution, when placing the service connector, the water pipe connected to the connector is aligned with the clearance groove and passed through; after the water pipe passes through, the inner wall of the clearance groove fits against the outer wall of the water pipe to form a snap, restricting the movement of the water pipe and the connector in the horizontal direction; at this time, the position of the connector is relatively fixed, and it can accurately contact the extrusion plate and drive the extrusion plate to move, ensuring the stability of the control switch triggering.

[0009] Optionally, the storage box has a recessed groove at the bottom to accommodate the service connector. When the service connector is located in the recessed groove, the service connector presses against the compression plate.

[0010] By adopting the above technical solution, the sink provides a dedicated space for the service joint, ensuring the correct positioning of the joint. Compared with flat placement, the sink can guide the joint into precise position through its own structure. After the joint is placed in the sink, its own weight or the force exerted during placement can be transmitted to the extrusion plate more directly and stably, ensuring the reliable operation of the extrusion plate.

[0011] Optionally, the storage box includes a box body and a cover. The cover is installed on the box body. When the cover blocks the box body, the cover presses against the service connector, causing the service connector to slide along the sink and press against the extrusion plate.

[0012] By adopting the above technical solution, the pressing action when sealing the box can force the connector to slide along the groove. Even if there is a slight deviation when the connector is placed, the position can be adjusted by sliding to ensure reliable pressure against the extrusion plate.

[0013] Optionally, the cap and the box body are connected by a snap-fit ​​connection.

[0014] By adopting the above technical solution, the snap-fit ​​connection is a convenient and reliable detachable connection method that can ensure that the cover remains stable after sealing the box.

[0015] Optionally, an overtake switch is also included, which is installed in the vehicle's cab and is connected to the vehicle's driving control system. When the overtake switch is pressed, the vehicle's driving restriction is lifted.

[0016] By adopting the above technical solution, under normal circumstances, the vehicle is started by placing the connector into the storage box and triggering the control switch. When the storage device malfunctions (such as damage to the extrusion plate or failure of the control switch), and it is confirmed that the connector has been returned to its position or that the vehicle needs to be moved without considering the connector's status, the operator presses the overpass switch in the cab. The overpass switch sends a signal directly to the vehicle driving control system to temporarily lift the driving restriction, and the vehicle can start normally. After the fault is cleared, the overpass switch is reset, and the device returns to normal logic.

[0017] Optionally, the overrunning switch is electrically connected to a display screen via the controller. The display screen is set with stored parameters and records and queries the operation records of the overrunning switch.

[0018] By adopting the above technical solution, installing a display screen and connecting it to the overpass switch, and setting the recording and storage parameters, such as the recorded content (time, date, etc.) and storage capacity, it is ensured that the display screen can accurately record and query the operation records of the overpass switch.

[0019] Optionally, a displacement sensor is provided inside the storage box and electrically connected to the controller for detecting the displacement of the extrusion plate.

[0020] By adopting the above technical solution, the displacement sensor detects the movement distance of the extrusion plate in real time. If the displacement reaches the preset threshold, it indicates that the extrusion plate has moved in place and the control switch has been effectively triggered, confirming that the joint is in normal position. If the displacement does not reach the threshold, it indicates that the extrusion plate is moving abnormally (such as being blocked by foreign objects or the joint not being placed in place). The displacement sensor can send a signal to the controller or external warning device to prompt the operator to check.

[0021] In summary, this application includes at least one of the following beneficial effects: 1. The vehicle is forced to start by placing the service connector into the storage box and pressing the control switch. The controller allows the vehicle to start. Combined with the design of sink, cover pressing, displacement sensing, etc., it ensures that the vehicle can only be started when the connector is in place, so as to avoid the potential risk of aircraft being pulled and damaged by the connector not being in place. 2. An overpass switch is added to the cab to address emergency vehicle relocation needs in case of device failure, and the display screen can trace the switch operation. Attached Figure Description

Detailed Implementation

[0024] The following is in conjunction with the appendix Figure 1 - Appendix Figure 6 This application will be described in further detail.

[0025] This application discloses a service connector storage device. It is mainly used in aircraft cleaning / sewage trucks, and its core purpose is to solve the safety hazard of "driving the vehicle before the service connector is returned to its proper position, resulting in damage to the aircraft."

[0026] Reference Figure 1 and Figure 2 A service connector storage device includes a frame and a storage box 10 mounted on the frame. The frame is connected to a water cart. The storage box 10 is used to hold service connectors 50. A pressing plate 20 is rotatably mounted inside the storage box 10. A control switch 30 is also fixedly installed inside the storage box 10. The control switch 30 is electrically connected to an external controller (not shown in the figure) via a wire. The controller is directly connected to a vehicle driving control system and can output commands to the vehicle driving control system to "start the vehicle" or "stop the vehicle from moving".

[0027] Reference Figure 2 A torsion spring 40 is installed inside the storage box 10 to keep the extrusion plate 20 in its natural state from contacting the control switch 30. The control switch 30 is equipped with an on / off switch 31, which is also mounted to the control switch 30 via the torsion spring 40. When the extrusion plate 20 does not press down on the on / off switch 31 of the control switch 30, the control switch 30 has no electrical signal output, and the controller continuously sends a "do not move" command to the vehicle driving control system, preventing the vehicle from starting.

[0028] Reference Figure 3 After the operation is completed, the operator places the service connector 50 into the storage box 10. During its descent, the connector contacts the pressing plate 20 and applies a downward force, causing the pressing plate 20 to rotate around its axis. The rotated pressing plate 20 presses against the control switch 30, triggering the control switch 30 and generating an electrical signal. This signal is transmitted to the controller via a wire. Upon receiving the signal, the controller immediately switches instructions and sends a "start allowed" signal to the vehicle driving control system, allowing the operator to start the vehicle normally. The torsion springs 40 on the control switch 30 and the pressing plate 20 primarily serve a reset function. When the service connector 50 is removed, the switch 31 and the pressing plate 20 reset, and the control switch 30 is in the off state.

[0029] Reference Figure 3 and Figure 4 To further improve the stability of connector placement and the reliability of triggering, a clearance groove 11 is provided through the bottom of the storage box 10. When the connector is placed, the water pipe 60 connected to the connector can extend through the clearance groove 11 to the outside of the storage box 10, and the outer wall of the water pipe 60 and the inner wall of the clearance groove 11 are tightly fitted to form a snap-fit. The snap-fit ​​restricts the horizontal displacement of the water pipe 60 and the connector, preventing the connector from shifting and causing the compression plate 20 to fail to trigger.

[0030] Reference Figure 4 The storage box 10 also has a recess 12 at the bottom, the size of which matches the service connector 50 and is specifically designed to accommodate the connector. When the connector is placed in the recess 12, its own weight can directly act on the extrusion plate 20, ensuring the stable operation of the extrusion plate 20.

[0031] Reference Figure 4 and Figure 5 Meanwhile, the storage box 10 consists of a box body 13 and a cover 14. The cover 14 is detachably connected to the box body 13 via a buckle 70. The buckle 70 connection facilitates quick opening and ensures stability after closing. When the cover 14 closes and seals the box body 13, the inner wall of the cover 14 presses the connector, driving the connector to slide along the groove 12 toward the extrusion plate 20. Even if the initial placement of the connector is off, it can be adjusted to the correct position by sliding, ensuring reliable pressure against the extrusion plate 20.

[0032] A service connector storage device is also equipped with an emergency and monitoring component. An overrun switch (not shown in the figure) is installed in the vehicle cab. The overrun switch is directly connected to the vehicle driving control system and does not need to be used under normal circumstances. Only when the core component fails (such as the extrusion plate 20 is damaged or the control switch 30 is malfunctioning) and it is confirmed that the connector has been returned to its position, the operator can press the overrun switch to temporarily release the vehicle driving restriction. After the fault is cleared, the switch resets and the device returns to normal logic.

[0033] The overrun switch is also connected to a display screen (not shown in the figure) via the controller. The display screen is pre-set with recording parameters (such as operation time and frequency). Each time the overrun switch is pressed, the display screen automatically records the operation information for easy subsequent query and monitoring. At the same time, a displacement sensor is installed in the storage box 10. The sensor is positioned directly opposite the extrusion plate 20 and can detect the rotational displacement of the extrusion plate 20 in real time. If the displacement reaches the preset threshold, it indicates that the extrusion plate 20 has moved in place, and the control switch 30 is effectively triggered. If the displacement is insufficient, it indicates that the connector is not in place or there is a foreign object stuck. The sensor will send a warning signal to the controller to prompt the operator to check.

[0034] The implementation principle of a service contact storage device according to an embodiment of this application.

[0035] Reference Figure 6 When the water truck approaches the aircraft and is in the working position, open the stainless steel safety storage box 10, take out the connector, and the squeezing plate 20 moves away from the control switch 30. The controller issues a command to prohibit the vehicle from moving. After the water truck finishes its work, put the service connector 50 back into the storage box 10. The squeezing plate 20 is squeezed, triggering the control switch 30. The signal is transmitted to the controller, which issues a command to allow the vehicle to move. In case the vehicle needs to be moved in an emergency, the overtaking switch can be pressed to move the vehicle. The overtaking switch signal is transmitted to the controller, which sends a command to the display to record the overtaking switch trigger time and number of times.

[0036] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
