Description
TECHNICAL FIELD
[0001] The utility model relates to the field of avionics chassis equipment, specifically to a cover plate of an aviation chassis. BACKGROUND
[0002] In the field of aviation equipment, the aviation chassis as the shell or structural component of the electrical equipment is the load bearing and protection device of the core component, and the installation and maintenance convenience of the internal electrical equipment module has an important influence on the overall operation efficiency and operation and maintenance cost of the equipment. At present, the connection between the functional module inside the aviation chassis and the electrical connector in the chassis generally adopts the plug-in cooperation mode. In order to realize the protection of the module and the structural integrity of the chassis panel, a cover plate is usually arranged at the installation position of the module corresponding to the chassis panel, and the module is enclosed in the chassis by the cover plate.
[0003] When the above-mentioned module is plugged or unplugged (such as module maintenance or replacement), the traditional operation mode needs to be executed in two steps: first, the operator opens the cover plate on the chassis panel to expose the module; second, the module is plugged or unplugged by means of a separately arranged plug-in or pull-out assisting mechanism (such as a special plug-in or pull-out handle, a lever type pull-out piece, etc.) to complete the separation or plug-in of the module and the electrical connector. In this process, the opening and closing actions of the cover plate and the plugging and unplugging actions of the module are completely independent, which leads to complicated operation steps, increases the workload of the operator, and significantly prolongs the overall operation time of the module plugging and unplugging. Especially in the scene of rapid maintenance or emergency repair of aviation equipment, which has high requirements on operation efficiency, the drawbacks of the traditional mode are more prominent, and it is difficult to meet the actual application requirements.
[0004] Therefore, in view of the technical problems of "independent operation of cover plate opening and closing and module plugging and unplugging, low efficiency" in the existing aviation chassis module plugging and unplugging process, a structure design capable of realizing the linkage of cover plate action and module plugging and unplugging action is needed to simplify the operation steps and improve the module plugging and unplugging efficiency.

Detailed Implementation
[0030] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.
[0031] In this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, without necessarily requiring or implying any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
[0032] As described in the background section, traditional methods for module insertion / removal (such as module maintenance or replacement) require two steps: First, the operator opens the cover on the chassis panel to expose the module; second, a separate insertion / removal mechanism (such as a dedicated insertion / removal handle or lever-type assist) is used to perform the insertion / removal operation to separate or connect the module to the electrical connector. In this process, the opening and closing of the cover is completely independent of the module insertion / removal action, resulting in cumbersome procedures. This not only increases the operator's workload but also significantly prolongs the overall operation time for module insertion / removal. The drawbacks of this traditional method are particularly pronounced in scenarios requiring high operational efficiency, such as rapid maintenance or emergency repairs of aviation equipment, making it difficult to meet practical application needs.
[0033] Based on the above situation, such as Figures 1-9 As shown, this embodiment provides a cover plate for an aircraft chassis, including a plate body 200. The plate body 200 covers the module insertion port of the aircraft chassis panel 100. One end of the plate body 200 is a connecting end and the other end is a locking end. The connecting end is rotatably connected to one side of the module insertion port by a pin 204, or the pin 204 is rotatably installed on a pin connecting seat 201, and the pin connecting seat is then fixedly installed on the aircraft chassis panel by screws.
[0034] A connecting rod mechanism is arranged on the inner side of the plate body 200, which comprises a power connecting rod 400, a transmission connecting rod 500 and a connecting seat 600. One end of the power connecting rod 400 is rotatably connected with the hinge seat 300 through a pin, and the hinge seat 300 is fixedly connected with the plate body through a screw. The other end of the power connecting rod 400 is rotatably connected with the transmission connecting rod 500 through a rotating pin. The other end of the transmission connecting rod 500 is rotatably connected with the connecting seat 600, and the connecting seat 600 is fixedly connected with the inner side of the aviation case panel 100 through a screw. The transmission connecting rod 500 has a protruding transmission part 501, which is inserted into a guide groove 800 arranged on the side of the module. Preferably, the transmission part is cylindrical. Figure 10 As shown in the figure, the guide groove 800 comprises a pulling and inserting part 801 and a sliding part 802. The pulling and inserting part 801 is away from the insertion end 701 of the module and has an angle with the insertion direction of the module. Preferably, the angle is ninety degrees. The insertion direction is the direction A shown in the figure. The sliding part extends along the length direction of the module (which is the same direction as the insertion direction) to the insertion end. When the plate body is closed to the module insertion port, the transmission part is located in the pulling and inserting part. Figure 10
[0035] The above technical features realize the opening and closing of the plate body and the pulling and inserting of the module through the transmission of the connecting rod mechanism, thereby improving the working efficiency of the operator. In the above technical features, before the plate body 200 is closed to the module insertion port of the aviation case panel 100, the operator inserts the module 700 into the module insertion port. In this process, the transmission part is located in the sliding part. When the module 700 is pushed to a certain position (such as when it cannot be pushed), the transmission part 501 slides into the pulling and inserting part 801 with the sliding part 802. When the plate body is closed, the transmission part located in the pulling and inserting part pushes the module to move to the inner side of the insertion port through the rotating force of the closed plate body. The mechanical transmission pushing force assists the accurate insertion of the module, reduces the manual force, and also avoids the poor contact caused by the insertion out of position. In the process of assisting the insertion, the transmission part gradually slides from the upper part of the pulling and inserting part (i.e. the end of the pulling and inserting part connected with the sliding part) to the lower part (i.e. the closed end of the pulling and inserting part) with the closing of the plate body. In this process, since the angle between the pulling and inserting part and the sliding part is 90°, the module can be pushed to move to the insertion direction, thereby realizing the assisting insertion.
[0036] In the opening process of the plate body, the power connecting rod rotates with the rotation of the plate body, and the power connecting rod pulls the transmission connecting rod after rotating by a sufficient angle. Since the transmission part 501 is located in the plug-in part 801 when the plate body is closed, when the plate body is continuously opened, the transmission part pulls the module to move outward in the plug-in part, and the rotational kinetic energy of the plate body is converted into the pulling-out force of the module through the transmission of the connecting rod, thereby reducing the pulling-out resistance, and the module can be quickly disassembled in a dense installation scene. After the pulling-out is assisted, the operator can take out the module. When the pulling-out is assisted, the transmission part 501 is gradually moved from the lower end to the upper end of the plug-in part with the opening of the plate body, and the upper end is in communication with the sliding part. Therefore, when the operator takes out the module, the transmission part slides in the sliding part until it slides out of the sliding part.
[0037] In order to enable the plate body to be automatically opened in the opening process, a torsional spring 205 for pushing the plate body to an open state is installed on the pin 204 in an embodiment.
[0038] By arranging the torsional spring on the pin, the torsional spring can be automatically reset, and the opening operation is simplified. The torsional spring on the pin enables the plate body to have a restoring force to maintain the open state, thereby reducing the pulling force of the operator when the cover is opened, and the labor-saving effect can be achieved. Meanwhile, the elastic force of the torsional spring can ensure that the plate body is stably positioned after being opened, and accidental closure is avoided.
[0039] Since the plate body can be automatically opened and reset under the action of the torsional spring, in an embodiment, the locking end of the plate body is installed with a lock tongue 202 through one or more elastic members 206 (such as a spring), the lock tongue 202 is provided with a handle 203, and a lock catch 900 is arranged on the aviation case panel 100. When the lock tongue is inserted into the lock catch, the plate body is in a locked state after being closed. When the lock is unlocked, the operator drives the lock tongue to separate from the lock catch by pushing the handle.
[0040] In the above technical features, the plate body is reliably locked by the cooperation of the elastic lock tongue and the lock catch. The elastic lock tongue of the locking end is triggered by the handle, and mechanical locking is formed after being inserted into the lock catch of the case panel, thereby preventing the plate body from being loosened under vibration and other working conditions. The elastic design can adapt to small tolerances to ensure tight locking, and the handle can be quickly unlocked by pressing, thereby achieving convenient operation.
[0041] The above description of the disclosed embodiments enables a person skilled in the art to implement or use the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
