Description

Technical Field

[0001] This utility model relates to a start-up protection device for an aircraft power vehicle socket, belonging to the technical field of aircraft power vehicle sockets. Background Technology

[0002] An aircraft power supply vehicle is a vehicle containing power supply equipment that supplies power to the aircraft's onboard equipment while the aircraft is on the ground. When the aircraft power supply vehicle is supplying power to the aircraft, the plug needs to be unplugged from the power supply vehicle's socket and plugged into the aircraft's power socket; after the aircraft power supply vehicle has finished supplying power to the aircraft, the plug needs to be unplugged from the aircraft's power socket and returned to the power supply vehicle's socket.

[0003] To prevent damage to the aircraft caused by the pilot accidentally driving the power supply vehicle away during power supply operations, existing technology provides a power supply vehicle socket activation protection device. This device includes a sensor installed in the power supply vehicle socket. When the socket is returned to its original position, the sensor is closed, allowing the vehicle's ignition system to operate normally. When the socket is not returned to its original position, the sensor is deactivated, preventing the ignition system from functioning. This ensures that the pilot will not accidentally drive the power supply vehicle away during power supply operations, thus preventing damage to the aircraft.

[0004] However, if the aircraft power supply vehicle is parked near the aircraft and the engine is not turned off, and power is directly supplied to the aircraft, the existing aircraft power supply vehicle socket start protection device still cannot prevent the pilot from accidentally driving the power supply vehicle away, thus posing a potential safety hazard to the aircraft. Utility Model Content

[0005] One objective of this invention is to provide an aircraft power cart socket start-up protection device that overcomes the defects of the prior art and ensures that the power cart cannot move even if the engine is not turned off during operation, thus avoiding unsafe incidents such as collisions or dragging between the power cart and the aircraft caused by human operation.

[0006] The above-mentioned objectives of this utility model are achieved by an aircraft power vehicle socket start-up protection device, which includes a sensor, a parking brake locking disc, a transmission disc, a rotary motor, and a controller.

[0007] The sensor is installed inside the power supply vehicle socket to sense whether the plug in the power supply vehicle socket is in place. The upper end of the parking brake locking disc has a groove adapted to the parking brake of the aircraft power supply vehicle. The parking brake locking disc is sleeved on the transmission disc. The transmission disc is connected to the rotary motor. The rotary motor is connected to the controller. A signal receiver is installed in the rotary motor.

[0008] When the plug in the power vehicle socket is not returned to its original position, the sensor disconnects and sends a sensor disconnect signal to the controller. After receiving the sensor disconnect signal, the controller sends a motor start signal to the signal receiver of the rotary motor to control the rotary motor to start, thereby driving the transmission disc and the parking brake locking disc to rotate. If the parking brake has been pulled up, the groove of the parking brake locking disc is rotated downward, so that the parking brake cannot be released downward into the groove.

[0009] When the plug in the power vehicle socket is returned to its original position, the sensor closes and sends a sensor closure signal to the controller. After receiving the sensor closure signal, the controller sends a motor stop signal to the signal receiver of the rotary motor, controlling the rotary motor to stop, thereby preventing the transmission disc and the parking brake locking disc from rotating. The groove of the parking brake locking disc remains at the top, thus not affecting the parking brake from releasing downward into the groove.

[0010] According to the above technical solution, the aircraft power cart socket start protection device of this utility model can achieve the following beneficial technical effects: it can ensure that even if the power cart is not turned off, the power cart cannot move when it is in operation, thus avoiding unsafe events such as collisions or dragging between the power cart and the aircraft caused by human operation.

[0011] Preferably, the aircraft power vehicle socket start-up protection device further includes an alarm, which is connected to the controller;

[0012] When the plug in the power vehicle socket is not returned to its original position, if the parking brake is not engaged, the parking brake locking disc and the parking brake will block each other, causing the rotation of the parking brake locking disc to be obstructed. The controller receives the obstruction signal and activates the alarm.

[0013] Preferably, the aircraft power vehicle socket start-up protection device also includes a mounting base for mounting the rotary motor.

[0014] Preferably, the transmission disk has a plurality of transmission teeth evenly arranged along the circumferential direction inside, the output shaft of the rotary motor has a drive disk on its circumferential surface, and the outer wall of the drive disk has a plurality of corresponding drive teeth evenly arranged along the circumferential direction, the drive teeth and the transmission teeth meshing and connected.

[0015] Preferably, the transmission disc is provided with a protruding snap-fit ​​portion, and the parking brake locking disc is provided with a corresponding snap-fit ​​groove, wherein the snap-fit ​​portion snaps into the snap-fit ​​groove.

[0016] Preferably, the snap-fit ​​portion has a stepped protrusion relative to the main surface of the transmission disk.

[0017] Preferably, the outer circumference of the transmission disc is provided with a plurality of positioning pins, and the transmission disc is connected to the parking brake locking disc through the positioning pins.

[0018] Preferably, the plurality of locating pins are evenly arranged along the outer circumference of the transmission disc.

[0019] Preferably, the controller is disposed in the side wall of the rotary motor.

[0020] Preferably, the alarm is mounted on the mounting base. Attached Figure Description

[0044] Figure 6 This is a schematic diagram showing the state of the aircraft power vehicle socket start protection device and parking brake together with an embodiment of the present invention.

[0045] like Figures 1 to 6 As shown, according to one embodiment of the present invention, the aircraft power vehicle socket start protection device includes a sensor, a parking brake locking disc 10, a transmission disc 20, a rotary motor 30, and a controller 70.

[0046] The sensor is installed inside the power supply vehicle socket to sense whether the plug in the power supply vehicle socket is in place. The upper end of the parking brake locking disc 10 is provided with a groove 11 that is compatible with the parking brake 100 of the aircraft power supply vehicle. The parking brake locking disc 10 is sleeved on the transmission disc 20 (that is, the transmission disc 20 is located in the radial interior of the parking brake locking disc 10). The transmission disc 20 is connected to the rotary motor 30. The rotary motor 30 is connected to the controller 70. A signal receiver is provided in the rotary motor 30.

[0047] When the plug in the power supply vehicle socket is not returned to its original position (which means that the power supply vehicle may be supplying power to the aircraft), the sensor is disconnected. The sensor sends a sensor disconnection signal to the controller 70. After receiving the sensor disconnection signal, the controller 70 sends a motor start signal to the signal receiver of the rotary motor 30, controlling the rotary motor 30 to start, thereby driving the transmission disc 20 and the parking brake locking disc 10 to rotate. If the parking brake 100 has been pulled up, the groove 11 of the parking brake locking disc 10 is rotated downward, so that the parking brake 100 cannot be released downward into the groove 11.

[0048] When the plug in the power supply vehicle socket is returned to its original position (meaning that the power supply vehicle is no longer supplying power to the aircraft), the sensor closes. The sensor sends a sensor closure signal to the controller 70. After receiving the sensor closure signal, the controller 70 sends a motor stop signal to the signal receiver of the rotary motor 30, controlling the rotary motor 30 to stop. This prevents the transmission disc 20 and the parking brake locking disc 10 from rotating. The groove 11 of the parking brake locking disc 10 remains at the top, thus not affecting the parking brake 100 from releasing downward into the groove 11.

[0049] According to the above technical solution, the aircraft power cart socket start protection device of this utility model can achieve the following beneficial technical effects: it can ensure that even if the power cart is not turned off, the power cart cannot move when it is in operation, thus avoiding unsafe events such as collisions or dragging between the power cart and the aircraft caused by human operation.

[0050] Specifically, this utility model proposes an aircraft power vehicle socket start-up protection device. When the power vehicle is in operation and the power vehicle is not turned off and the plug in the power vehicle socket is not returned to its original position, if the parking brake 100 has been pulled up and the driver wants to release the parking brake 100 downwards and drive the power vehicle away, the sensor sends a sensor disconnect signal to the controller 70. The controller 70 controls the rotary motor 30 to start, thereby driving the transmission disc 20 and the parking brake locking disc 10 to rotate. The groove 11 of the parking brake locking disc 10 is rotated downwards, so that the parking brake 100 cannot be released downwards into the groove 11, preventing the driver from driving the power vehicle away and avoiding unsafe events such as collisions or dragging between the power vehicle and the aircraft caused by human operation. Only when the plug in the power vehicle socket is returned to its original position can the driver release the parking brake 100 downwards and drive the power vehicle away.

[0051] In some embodiments, such as Figures 1 to 6 As shown, the aircraft power vehicle socket start protection device also includes an alarm 50, which is connected to the controller 70;

[0052] When the plug in the power supply vehicle's socket is not returned to its original position, the sensor disconnects and sends a disconnect signal to the controller 70. Upon receiving the disconnect signal, the controller 70 sends a motor start signal to the signal receiver of the rotary motor 30, controlling the rotary motor 30 to start. This causes the transmission disc 20 and the parking brake locking disc 10 to rotate. If the parking brake 100 is not engaged, the parking brake locking disc 10 and the parking brake 100 will block each other, causing the rotation of the parking brake locking disc 10 to be obstructed. Upon receiving the obstruction signal, the controller 70 activates the alarm 50, issuing an alarm to remind the driver to engage the parking brake 100, ensuring that the power supply vehicle cannot move. This mechanism ensures that the power supply vehicle cannot move during operation, effectively preventing safety hazards such as collisions or dragging between the power supply vehicle and the aircraft.

[0053] Preferably, the controller 70 is connected to the sensor, the rotary motor 30 (i.e., the signal receiver of the rotary motor 30) and the alarm 50 via a signal connection, enabling signal communication.

[0054] Preferably, the alarm 50 can be, for example, a buzzer alarm or a strobe alarm, which can emit a buzzer or strobe alarm during operation to remind the driver to engage the parking brake 100, ensuring that the vehicle cannot move while the power supply vehicle is in operation.

[0055] In some embodiments, such as Figures 1 to 6 As shown, the aircraft power vehicle socket start protection device also includes a mounting base 40 for mounting the rotary motor 30, thereby ensuring the installation stability of the rotary motor 30 and its associated transmission disc 20 and parking brake locking disc 10.

[0056] In some embodiments, such as Figures 1 to 6 As shown, the transmission disk 20 has multiple transmission teeth 21 evenly arranged along the circumferential direction inside. The output shaft of the rotary motor 30 has a drive disk on its circumferential surface, and the outer wall of the drive disk has multiple corresponding drive teeth 31 evenly arranged along the circumferential direction. The drive teeth 31 and the transmission teeth 21 mesh with each other. The cooperation between the transmission teeth 21 and the drive teeth 31 can improve the transmission force and ensure the stability of the transmission, thereby ensuring the actual use effect.

[0057] In some embodiments, such as Figures 1 to 6 As shown, the transmission disc 20 is provided with a protruding snap-fit ​​portion 22, and the parking brake locking disc 10 is provided with a corresponding snap-fit ​​groove, in which the snap-fit ​​portion 22 snaps into the snap-fit ​​groove. By providing the snap-fit ​​groove, the installation stability of the snap-fit ​​portion 22 can be ensured, and the connection stability between the transmission disc 20 and the parking brake locking disc 10 can be ensured by the cooperation of the snap-fit ​​portion 22 and the snap-fit ​​groove.

[0058] Preferably, such as Figures 1 to 6 As shown, the snap-fit ​​portion 22 has a stepped protrusion relative to the main disk surface of the transmission disk 20 (that is, most of the disk surface of the transmission disk 20 except for the snap-fit ​​portion 22).

[0059] In some embodiments, such as Figures 1 to 6 As shown, the outer circumference of the transmission disc 20 is provided with multiple positioning pins 60. The transmission disc 20 and the parking brake locking disc 10 are connected by the positioning pins 60, thereby fixing the relative position of the transmission disc 20 and the parking brake locking disc 10 and ensuring reliable locking.

[0060] Preferably, such as Figures 1 to 6 As shown, multiple locating pins 60 are evenly arranged along the outer edge of the circumference of the transmission disc 20.

[0061] In some embodiments, such as Figures 1 to 6As shown, the controller 70 is housed in the side wall of the rotary motor 30. This preferred installation position of the controller 70 saves space occupied by the entire aircraft power cart socket start-up protection device, reduces costs, does not affect the normal operation of the aircraft power cart, and ensures signal communication between the controller 70 and other related components.

[0062] In some embodiments, such as Figures 1 to 6 As shown, the alarm 50 is mounted on the mounting base 40. Preferably, as... Figures 1 to 6 As shown, the alarm 50 is mounted on the inner side of the mounting base 40 facing the rotary motor 30. This preferred mounting position of the alarm 50 saves space occupied by the entire aircraft power cart socket start-up protection device, reduces costs, does not affect the normal operation of the aircraft power cart, and ensures signal communication between the controller 70 and the alarm 50.

[0063] The specific embodiments of this utility model have been described above. However, those skilled in the art will understand that the above specific embodiments do not constitute a limitation on this utility model. Those skilled in the art can make various modifications based on the above disclosure without exceeding the scope of this utility model.
