Description

Technical Field

[0001] This utility model relates to the field of protection devices, specifically a remote control panel protection device for an airborne emergency positioning transmitter. Background Technology

[0002] In aviation safety, aircraft cabins are equipped with airborne emergency locator transmitters. Their core function is to automatically or manually transmit a distress signal at a specific frequency in the event of a serious accident such as an emergency landing or crash. This signal can be received by satellites and ground search and rescue stations, helping to quickly locate the aircraft and buying valuable time for subsequent rescue efforts. To facilitate timely operation by the crew in emergencies, the airborne emergency locator transmitter is equipped with a remote control panel. This panel is typically integrated into a prominent and easily accessible area such as the cockpit instrument panel or control console, and includes buttons for starting, stopping, and testing the transmitter. Crew members can control the transmitter's operating status through simple operations such as pressing and toggling.

[0003] However, the remote control panel of current airborne emergency locator transmitters lacks protective devices. During routine aircraft operation, normal crew operation, and equipment inspection and maintenance by ground maintenance personnel, the control panel is exposed to the open environment of the cockpit. Crew members may accidentally touch or misoperate the control panel while operating other equipment, or maintenance personnel may accidentally touch the function buttons while cleaning, checking lines, or debugging equipment. This could cause the emergency locator transmitter to transmit aircraft distress signals unintentionally. Such unintentional transmissions consume valuable emergency communication frequency resources, disrupt the communication order of normal rescue operations, and may cause distress signals from aircraft in genuine emergencies to be drowned out by interference signals, delaying rescue opportunities, and even wasting resources and causing chaos in rescue operations, seriously affecting the effectiveness and reliability of aviation safety assurance.

[0004] Therefore, we propose a protection device for the remote control panel of an airborne emergency positioning transmitter to prevent accidental transmission of distress signals due to accidental touch of the remote control panel. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to practical needs, and provide a remote control panel protection device for an airborne emergency positioning transmitter. This addresses the current technical problem where, during routine aircraft operation, crew operation, and ground maintenance personnel conducting equipment inspections and maintenance, the control panel is exposed in the open cockpit environment. Crew members may accidentally touch or misoperate the control panel while operating other equipment, or maintenance personnel may accidentally touch function buttons during cleaning, wiring checks, or equipment debugging. This can lead to the emergency positioning transmitter unintentionally transmitting aircraft distress signals. Such unintentional transmissions consume valuable emergency communication frequency resources, disrupt normal rescue communication, and may drown out distress signals from aircraft in genuine emergencies, delaying rescue efforts, wasting resources, and causing chaos in rescue operations, seriously affecting the effectiveness and reliability of aviation safety assurance.

[0006] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: a remote control panel protection device for an airborne emergency positioning transmitter is designed, including a remote control panel body and a front panel. The front panel is installed at the front end of the remote control panel body. A button through hole is provided on the surface of the front panel, and a control switch extends into the button through hole. A base is provided on the surface of the front panel, and a shaft is installed inside the base. A torsion spring passes through the outside of the shaft, and a protective cover passes through one end of the shaft. A U-shaped groove is opened on the edge of the other end of the protective cover, and the control switch passes through the U-shaped groove, restricting the control switch to the ARM position.

[0007] Preferably, the torsion end of the torsion spring is fixed to the protective cover.

[0008] Preferably, copper nuts are provided at both the upper and lower ends of the base, and a first screw is threaded into the copper nut.

[0009] Preferably, the base is connected to the front panel by a second screw.

[0010] Preferably, a front panel base is mounted on the rear end of the front panel.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model can effectively prevent accidental contact and avoid occupying emergency communication frequencies due to accidental transmission, thereby reducing interference with the normal work of emergency rescue organizations. It not only helps to improve the efficiency of emergency rescue and ensures that rescue resources can be accurately and timely allocated to where they are truly needed, but also reduces the unnecessary workload of emergency rescue organizations when dealing with accidental transmission signals. It has high application value in the field of preventing accidental transmission of airborne emergency positioning transmitters. Attached Figure Description

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0019] Example 1: A remote control panel protection device for an airborne emergency positioning transmitter, see [link / reference] Figures 1 to 4The system includes a remote control panel body 10 and a front panel 1. The front panel 1 is mounted on the front end of the remote control panel body 10. The surface of the front panel 1 has a button through-hole, into which a control switch extends. A base 3 is mounted on the surface of the front panel 1, and a shaft 5 is installed inside the base 3. A torsion spring 6 passes through the shaft 5, and one end of a protective cover 4 passes through the shaft 5. A U-shaped groove is formed on the edge of the other end of the protective cover 4. The control switch passes through the U-shaped groove, limiting the control switch to the ARM position. Under normal conditions, the protective device relies on the torque generated by the torsion spring 6 to firmly hold the U-shaped groove on the protective cover 4 in the closed position. The U-shaped groove can cooperate with the selector switch on the remote control panel of the airborne emergency locator transmitter in the aircraft cockpit to limit the selector switch, limiting it to the ARM position and preventing it from shifting without human intervention. When the remote control panel's selector switch needs to be operated, the operator only needs to manually rotate the protective cover 4. Rotating the protective cover 4 will move the U-shaped retaining groove along with it. As the U-shaped retaining groove moves, its original limiting effect on the selector switch is released, and the selector switch is now in a freely operable state. The operator can then operate it according to actual needs. This protective device can prevent personnel entering the aircraft cockpit from accidentally switching the remote control panel's switch to the ON position during daily activities or unintentional touches. Once the switch is accidentally switched to the ON position, the emergency locator transmitter may start transmitting in non-emergency situations, which will not only waste valuable emergency resources but also easily interfere with normal aviation communications and emergency rescue operations. The existence of this protective device fundamentally eliminates such accidental transmissions, providing reliable protection for aircraft flight safety and the standardized use of the emergency locator transmitter.

[0020] For details, see Figure 2 The torsion end of the torsion spring 6 is fixed to the protective cover 4.

[0021] Further, see Figure 1 and Figure 2 The base 3 has copper nuts 9 at both the top and bottom ends, and the copper nuts 9 are internally threaded with first screws 7.

[0022] It is worth noting that, see Figure 4 The base 3 is connected to the front panel 1 by a second screw 8.

[0023] It is worth noting that, see Figure 3 The front panel 1 has a front panel base 2 installed at its rear end.

[0024] When using a remote control panel protection device for an airborne emergency locator transmitter, under normal conditions, the protection device relies on the torque generated by the torsion spring 6 to firmly hold the U-shaped retaining groove on the protective cover 4 in the closed position. The U-shaped retaining groove can cooperate with the selector switch on the remote control panel of the airborne emergency locator transmitter in the aircraft cockpit, acting as a limit switch to restrict it to the ARM position, preventing it from changing position without manual operation. When it is necessary to operate the selector switch of the remote control panel, the operator only needs to manually rotate the protective cover 4. Rotating the protective cover 4 will move the U-shaped retaining groove along with it. As the U-shaped retaining groove moves, its original position... The limiting effect of this selector switch is released, and the selector switch is now freely operable. Operators can operate it according to actual needs. This protective device can prevent personnel entering the aircraft cockpit from accidentally switching the remote control panel switch to the ON position during daily activities or unintentional touch. Once the switch is accidentally switched to the ON position, the emergency locator transmitter may start transmitting in non-emergency situations, which will not only waste valuable emergency resources, but also easily interfere with normal aviation communications and emergency rescue operations. The existence of this protective device fundamentally eliminates such accidental transmissions, providing a reliable guarantee for aircraft flight safety and the standardized use of the emergency locator transmitter.
