Description

Technical Field

[0001] This utility model relates to the field of electronic registration card technology, and in particular to an electronic registration card used for aircraft maintenance operations. Background Technology

[0002] In aircraft maintenance operations, the accuracy and traceability of maintenance records are directly related to flight safety. Registration cards, as a key management tool for maintenance operations, are mainly used to record the work content, operating procedures, inspection results, and completion status of maintenance personnel. They are an important basis for ensuring that maintenance quality meets industry standards. Traditional maintenance operations typically use paper registration cards, requiring maintenance personnel to manually fill in maintenance information and sign for confirmation, thus enabling accountability.

[0003] However, paper registration cards have many drawbacks in practical applications: First, paper registration cards are easily damaged and difficult to preserve for long periods. Due to the complex environment of aircraft maintenance operations, these problems are particularly prominent, making it very easy for maintenance record information to become blurred or lost. Second, maintenance records usually need to be preserved for a long time, but paper documents are inefficient in the archiving, retrieval, and access processes, and occupy a lot of storage space, increasing management costs. More importantly, paper registration cards rely on manual filling and signatures, lacking an effective identity verification mechanism, which makes them prone to violations such as proxy signing, forgery, or retroactive signing, casting doubt on the authenticity and credibility of maintenance records. Especially in the field of aircraft maintenance, which has high safety requirements, if maintenance personnel do not operate according to procedures but evade responsibility by signing on behalf of others, critical maintenance steps may be missed. In addition, during accident investigations or compliance audits, paper records have poor traceability, making it difficult to quickly locate the problem area, affecting fault analysis and responsibility determination. Utility Model Content

Detailed Implementation

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

[0019] Example: An electronic registration card for aircraft maintenance operations, combined with 1- Figure 5 As shown in the figure, the device includes: a housing 1; a touchscreen 2 fixedly mounted on the housing 1; a main processor 3 fixedly mounted inside the housing 1, electrically connected to the touchscreen 2, which displays the content output by the main processor 3 and receives input signals from the touchscreen 2 to support interactive operations by maintenance personnel; a battery 4 fixedly mounted inside the housing 1, electrically connected to the touchscreen 2 and the main processor 3 to power them; a charging port 5 on the housing 1, electrically connected to the battery 4, which is charged from the outside; a signature board 6 fixedly mounted on the housing 1, electrically connected to the main processor 3 and the battery 4, which powers the signature board 6; a shelf 7 on the housing 1; a pen 8 fixedly mounted on the shelf 7, which records the writing on the signature board 6 and transmits the data to the main processor 3; an electric slide rail 9 fixedly mounted on the housing 1; a cover plate 10 covering the signature board 6; and a connecting block 11 fixedly mounted on the cover plate 10, which is fixed to the control end of the electric slide rail 9.

[0020] Using this electronic registration card, key information that needs to be filled in during maintenance work is pre-set, and signature samples of maintenance personnel are collected. The signature data is then bound to the maintenance personnel's identity information and stored in the main processor 3.

[0021] During the maintenance process, the touch screen 2 dynamically displays the work instructions, guiding the maintenance personnel to complete the operation step by step. After the work is completed, the maintenance personnel use the pen 8 to sign on the signature board 6. The signature board 6 feeds back the handwriting data to the main processor 3 in real time. The main processor 3 uses a handwriting comparison algorithm to verify the matching degree between the current signature and the pre-stored sample, confirming the authenticity of the maintenance personnel's identity. After each signature verification is passed, the operator controls the touch screen 2 to switch to the next work content interface to ensure step-by-step recording. The main processor 3 then performs structured integration of the signature time, work content, and personnel information, and encrypts and stores it in a local or cloud database. Finally, when the electronic registration card is finished, the pen 8 is placed back on the shelf 7, and the electric slide rail 9 is operated to drive the cover 10 to close, forming physical protection for the signature board 6 and the pen 8.

[0022] Using this electronic registration card, dynamic handwriting comparison technology will be used to prevent proxy signing and forgery, ensuring the authenticity of maintenance records; the main processor 3 will uniformly archive work data, supporting multi-dimensional retrieval and auditing by time, personnel, work order, etc., to facilitate data traceability; and the cover plate 10 will be used to protect the signature part of this electronic registration card to prevent damage caused by external factors and extend the service life of this electronic registration card.

[0023] Combination Figure 1 and Figure 4 As shown, the placement rack 7 is slidably mounted on the outer casing 1, and also includes: a pressure plate 12 slidably mounted on the outer casing 1, the upper end of the pressure plate 12 being fixed to the placement rack 7, the pressure plate 12 being provided with an oblique contact surface, and the cover plate 10 moving will contact the oblique contact surface of the pressure plate 12; and a return spring 13 fixedly mounted between the placement rack 7 and the outer casing 1.

[0024] When the cover plate 10 moves to the position covering the signature plate 6, the cover plate 10 gradually contacts the pressure plate 12. Through the guiding action of its upper inclined contact surface, the pressure plate 12 drives the placement rack 7 and the pen 8 to retract synchronously into the outer shell 1, so that the pen 8 is completely retracted into the outer shell 1, thereby effectively preventing the pen 8 from accidentally falling off the placement rack 7 and ensuring the normal use function of this electronic registration card. Conversely, when the cover plate 10 is removed from the surface of the signature plate 6 and the pressure plate 12, the placement rack 7 automatically unfolds outward under the restoring action of the return spring 13, so that the pen 8 returns to the standby state for easy access at any time.

[0025] Combination Figure 1 and Figure 4As shown, it also includes: a roller 14 mounted on the cover plate 10, the roller 14 being located on the part of the cover plate 10 that contacts the pressure plate 12, the rolling friction reducing wear between the cover plate 10 and the pressure plate 12, extending the service life of the electronic registration card; a soft rubber block 15 fixedly mounted on the placement rack 7, the soft rubber block 15 both cushioning the vibration of the pen 8 and reducing frictional wear, ensuring the long-term stable use of the pen 8; a light shield 16 fixedly mounted on the upper part of the outer shell 1, the light shield 16 covering the area above the touch screen 2, effectively blocking direct sunlight, ensuring the display clarity of the touch screen 2, and providing safety protection for the touch screen 2; and a curved handle 17 fixedly mounted on the upper part of the outer shell 1, the curved handle 17 facilitating the hanging and fixing of the electronic registration card or allowing maintenance personnel to carry it with one hand, thereby improving the ease of use of the electronic registration card in on-site operations.
