Description

Technical Field

[0001] The invention relates to the technical field of non-powered equipment of aviation aircraft, and in particular to an electronic wheel chock brake mechanism. Background Art

[0002] In the current storage and use of non-powered equipment, traditional brake mechanisms mainly rely on metal wheel chocks or rubber wheel chocks to prevent the equipment from slipping. Although these metal wheel chocks and rubber wheel chocks can play a blocking role, they only play a simple role in preventing the equipment from slipping and do not effectively lock it. Due to the lack of an effective locking mechanism, these devices may be towed away by unauthorized personnel, resulting in the loss or inability to find the equipment.

[0003] In addition, in emergency situations, traditional brake mechanisms usually require manual operation, which is inconvenient to operate. This mechanical brake mechanism has certain safety hazards, and the braking process is relatively slow, which cannot quickly respond to sudden emergencies. Moreover, traditional brake components (such as metal wheel chocks and rubber wheel chocks) are often inconvenient to store and are easy to lose, further affecting the management and use efficiency of the equipment.

[0004] With the advancement of intelligent and automated technology, traditional mechanical brake mechanisms can no longer meet the needs of modern non-powered equipment. Therefore, it is particularly important to develop an electronic wheel chock brake mechanism that can provide higher safety, convenience, easy operation, and remote control. Summary of the invention

[0005] The purpose of the present invention is to solve the shortcomings of the prior art and to propose an electronic wheel chock brake mechanism.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0011] Preferably, the electrical control box comprises an electrical box, a lithium iron phosphate battery pack and a controller are arranged inside the electrical box, and a charging port and an antenna are arranged on an outer wall of the electrical box.

[0012] Preferably, the controller is electrically connected to the electric push rod via an electrical connector.

[0013] Preferably, the electrical control box and the electric push rod constitute an electrical component, and the lithium iron phosphate battery pack supplies power to the electrical component.

[0014] Preferably, an outer wheel axle and a traction assembly are provided on the outer wheel axle.

[0015] Preferably, the brake pad is bonded to the upper half and the lower half by brake pad glue.

[0016] The beneficial effects of the present invention are:

[0018] 2. Improve safety and work efficiency: Due to the use of electrical control and hydraulic drive, the brake release and locking process does not require manual operation and can be completed quickly and accurately, reducing safety hazards and slow braking problems caused by improper or slow manual operation, which is especially important for rapid braking in emergency situations.

[0019] 3. Simplified storage and maintenance: The brake mechanism avoids the cumbersome storage and loss of traditional mechanical parts through electrical control and hydraulic operation. All key components are integrated in a compact electrical control box, which is convenient for storage and management, and has high durability, reducing maintenance costs and management difficulties.

[0020] 4. Save battery power: Through reasonable electrical design and control, the system can judge the battery consumption according to the completion of the braking or releasing action, thereby saving battery power, extending the battery life, and reducing operational failures caused by battery exhaustion.

[0021] 5. Applicable to various non-powered equipment: The electronic wheel chock brake mechanism is not only suitable for various non-powered equipment that requires braking, but also can realize accurate positioning and monitoring of the equipment through the software system, further improving the intelligent level of equipment management.

[0056] As a preferred embodiment of the present invention, the brake pad 22 is bonded to the upper half 20 and the lower half 21 by the brake pad adhesive 23 .

[0057] The working principle of the present invention is as follows:

[0058] Brake release process: During use, the operator sends a brake release command through the APP or the host computer. After the controller 34 receives the command through the antenna 33, it decodes and performs logical operations, and issues a command to release the brake. The controller 34 controls the electric push rod 6 to extend through the electrical connector 35. The extension of the electric push rod 6 causes the brake hydraulic oil to flow from the master brake cylinder 9 into the brake slave cylinder 13. The push rod of the brake slave cylinder 13 extends, thereby driving the spring 26 to lengthen. The spring 26 drives the upper half 20 and the lower half 21 to separate through the spring adjustment rod 25 and the fixed block 24. When the upper half 20 and the lower half 21 are separated, the brake pad 22 is separated from the inner wheel shaft 16, the brake is released, and the equipment can be towed freely. After the electric push rod 6 is extended to the set time, the brake is completely released and the controller 34 stops supplying power.

[0059] Braking process: the operator sends a braking command through the APP or the host computer, the controller 34 receives the command through the antenna 33, and issues a braking command after decoding and calculation. The controller 34 controls the electric push rod 6 to retract through the electrical connector 35. The retraction action of the electric push rod 6 causes the hydraulic oil to flow from the brake cylinder 13 back to the brake master cylinder 9. The push rod of the brake cylinder 13 retracts, and the spring 26 begins to retract, driving the upper half 20 and the lower half 21 to retract. The upper half 20 and the lower half 21 are closed, and the brake pad 22 is pressed against the inner wheel shaft 16. The brake takes effect and the equipment cannot be towed. After the electric push rod 6 retracts to the set time, the brake is completed and the controller 34 stops supplying power.

[0060] Electrical control system: The electronic wheel chock brake mechanism works through the cooperation of the electrical control box 5 and the electric push rod 6, and is powered by the lithium iron phosphate battery pack 31 to ensure the stable operation of the entire electrical component. When the battery power is low, it is charged through the charging port 32 to ensure uninterrupted operation of the equipment during continuous use.

[0061] Through the above working principle, the electronic wheel chock brake mechanism can achieve precise control of non-powered equipment, effective braking and brake release operations, greatly improving the safety, operational convenience and work efficiency of the equipment.

[0062] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
