Description

Technical Field

[0001] The present invention relates to the technical field of airborne electronic equipment mounting brackets, and particularly provides a mounting bracket with a docking-in-place indication function and its usage method. Background Art

[0002] The fixing methods between airborne equipment and the mounting bracket are mainly divided into Class A locking and Class B locking. Among them, due to the particularity of its principle, for the Class B locking device, only when the connector mounting panel on the chassis reaches the designed distance from the connector mounting panel on the mounting bracket can the Class B locking device be erected and locked with the docking locking mechanism. Therefore, there is no risk of the equipment not being docked in place with the mounting bracket. However, for the Class A locking device, the chassis needs to be continuously pushed in forcefully, and after manually determining that the docking is in place, it is then locked and fixed. There is a risk that the chassis and the mounting bracket are locked when they are not docked in place. When the chassis and the mounting bracket are not docked in place, the contact length of the connector will be insufficient. Under the action of strong vibration loads, it may cause momentary interruption of the connector signal, affecting the operation of the equipment and the system, and seriously affecting the flight safety of the aircraft.

[0003] At present, the vast majority of chassis products on the aircraft use Class A locking devices to fix the equipment. There is no special structure to identify whether the chassis and the mounting bracket are docked in place after docking. Due to the narrow installation space on the aircraft, it is very difficult to measure the distance between the connector mounting panel on the chassis and the connector mounting panel on the mounting bracket, and thus it is impossible to determine whether the equipment is docked in place. Summary of the Invention

[0004] To solve the above problems, the present invention proposes a mounting bracket with a docking-in-place indication function and its usage method. When the chassis and the mounting bracket are docked in place, the present invention can indicate whether the chassis and the mounting bracket are docked in place through the docking-in-place indication mechanism, ensuring reliable docking between the equipment and the mounting bracket, and greatly improving the reliability and operability of equipment connection.

[0005] To achieve the above object, the technical solution adopted by the present invention is: a mounting bracket with a docking-in-place indication function, comprising:

[0006] A bottom plate, including a horizontal plate and first and second side plates vertically arranged on both sides above the horizontal plate;

[0007] A mounting panel, vertically fixed on the rear upper surface of the horizontal plate and between the first and second side plates;

[0008] An elastic component, longitudinally installed at one end of the mounting panel adjacent to the second side plate;

[0009] A plurality of positioning blocks, linearly distributed and fixedly spaced on the inner wall surface of the second side plate;

[0010] A docking-in-place indicating mechanism for indicating that the chassis is docked in place, one end of which is fixed to the elastic component, and the other end is inserted into a plurality of positioning blocks, and the elastic component drives the docking-in-place mechanism to move back and forth along the second side plate.

[0011] Further, the docking-in-place indicating mechanism includes a moving marking rod longitudinally inserted into the plurality of positioning blocks and capable of moving back and forth in the positioning blocks, and a connecting rod vertically fixed to the end of the moving marking rod. The connecting rod is fixed to the elastic component through a connecting piece, and a marking line for indicating that the device is docked in place is provided on the moving marking rod. When the chassis is docked in place, the marking line is flush with the front end face of the foremost positioning block on the second side plate.

[0012] Further, the elastic component includes a screw cap, a positioning sleeve, a core rod, a spring, a four-groove nut and a push rod. The screw cap is threadedly connected to the end of the positioning sleeve. The core rod is installed in the inner cavity of the positioning sleeve. The spring is placed in the inner cavity at the tail end of the push rod. The end of the push rod is sleeved outside the core rod, and the end of the spring contacts the front end face of the core rod. The outer peripheral surface of the end of the push rod is in abutting fit with the inner peripheral surface of the front end of the positioning sleeve through a stepped surface to limit the moving position of the push rod. A screw hole is axially provided at the front end of the push rod for installing a connecting piece to realize fixation with the connecting rod. The four-groove nut is installed on the outside of the positioning sleeve through threads, and the front end of the positioning sleeve is provided with a positioning platform extending outwardly.

[0013] Further, the positioning block includes a rectangular block body, and a through hole matching the shape of the moving marking rod is provided in the rectangular block body, and the rectangular block body is fixed to the second side plate by screws.

[0014] Further, the through hole is rectangular, and the moving marking rod is rectangular strip-shaped.

[0015] Further, the connecting piece is a cross-slot countersunk head screw.

[0016] Further, the mounting bracket further includes two bases, which are respectively installed on both sides of the bottom of the horizontal plate through bottom connectors and shock absorbers.

[0017] Further, the mounting bracket further includes two A-type set screws, which are respectively installed on both sides of the front end of the horizontal plate.

[0018] Further, the mounting bracket further includes two positioning pins, which are respectively installed on the mounting panel for docking with the positioning sleeves of the chassis.

[0019] The present invention further provides a method for using the above mounting bracket with a docking-in-place indicating function, which specifically includes the following steps:

[0020] Step 1: First, determine the position where the chassis is in place when docked on the mounting rack according to the theoretical distance required for the installation panel to be in place after docking with the connector on the chassis. Then, draw a marking line on the moving marking rod and determine the position of the frontmost positioning block so that when the chassis is docked in place, the marking line coincides exactly with the front face of the frontmost positioning block on the second side plate.

[0021] Step 2: Push the chassis placed on the horizontal plate in the docking direction of the connector of the mounting panel of the mounting rack. The rear mounting plate of the chassis contacts the connecting rod of the docking-in-place indicating mechanism, and slides the connecting rod together with the ejector rod of the elastic component in the docking direction. At the same time, the spring in the elastic component is compressed, and the end of the moving marking rod gradually approaches the end face of the positioning block. When the docking between the chassis and the mounting rack is in place, the marking line coincides exactly with the front face of the frontmost positioning block on the second side plate. Then, use 2 A-type set screws to lock the chassis.

[0022] Step 3: When the chassis is pulled out, the spring in the elastic component resets, and the ejector rod drives the docking-in-place indicating mechanism to return to the initial position before the chassis is docked.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] (1) The positions where the elastic component and the in-place indicating mechanism of the present invention are installed are two gap positions between the mounting rack and the connection of the chassis. One is located at the side gap between the chassis and the mounting rack, and the other is located at the gap between the rear mounting plate of the chassis and the connector mounting panel on the mounting rack. These two gaps exist at the positions after docking all mounting racks and chassis equipment, and will not cause an increase in the external dimensions of the mounting rack.

[0025] (2) The present invention realizes that it is possible to identify whether the docking between the chassis and the mounting rack is in place at the front end of the mounting rack, avoiding the inconvenience caused by observing whether the docking state is qualified at the top and side of the mounting rack; it is possible to complete the determination of whether the equipment is docked in place without any extra operations on the machine. The movement of the docking-in-place indicating mechanism is realized only during the docking process between the chassis and the mounting rack. It is judged whether to continue to push the equipment according to the indicated position, ensuring the docking in place of the mounting rack and the equipment, and being convenient for observation.

[0026] (3) When designing the structure, the influence of the chassis equipment installed on the mounting rack and the mounting rack itself on the structural strength of the in-place indicating mechanism is fully avoided. During actual use, this structure only bears the load of its own weight under the aircraft use conditions, making it have high reliability.

[0027] (4) The docking-in-place indicating mechanism can be applied to all mounting rack products fixed by A-type locking devices, with strong applicability. Description of the Drawings

[0044] The number of the positioning blocks 4 is at least two, and the foremost positioning block 4 is arranged at a position adjacent to the front end face of the bottom plate 1. The specific position is determined according to the theoretical distance required for the mounting panel 2 to be docked in place with the rear mounting plate of the connector on the chassis, so as to determine the position where the chassis is docked in place on the mounting rack.

[0045] The docking-in-place indicating mechanism 5 for indicating that the chassis is docked in place has one end fixed to the elastic component 3 and the other end passing through a plurality of positioning blocks 4.

[0046] Refer to Figure 7 , the docking-in-place indicating mechanism 5 includes a moving marking rod 51 longitudinally passing through the plurality of positioning blocks 4 and capable of moving back and forth in the positioning blocks 4. The positioning blocks 4 ensure that the moving marking rod 51 moves in a straight line, and a connecting rod 52 vertically fixed to the end of the moving marking rod 51. The connecting rod 52 is fixed to the elastic component 3 through a connecting member 20, and a marking line 511 for indicating that the device is docked in place is provided on the moving marking rod 51. When the chassis is docked in place, the marking line 511 is flush with the front end face of the foremost positioning block 4 on the second side plate 13.

[0047] Refer to Figure 6 , the elastic component 3 includes a screw cap 31, a positioning sleeve 32, a core rod 33, a spring 34, a four-groove nut 35 and a push rod 36. The screw cap 31 is threadedly connected to the end of the positioning sleeve 32. The core rod 33 is installed in the internal cavity of the positioning sleeve 32. The spring 34 is placed in the internal cavity at the tail end of the push rod 36. The end of the push rod 36 is sleeved outside the core rod 33, and the end of the spring 34 is in contact with the front end face of the core rod 33. The outer peripheral surface of the end of the push rod 36 is in abutting fit with the inner peripheral surface of the front end of the positioning sleeve 32 through a stepped surface to limit the moving position of the push rod 36. A screw hole is axially provided at the front end of the push rod 36 for installing the connecting member 20 to realize the fixation with the connecting rod 52. The four-groove nut 35 is threadedly installed outside the positioning sleeve 32, and a positioning platform 321 extending outward is provided at the front end of the positioning sleeve 32. The end face of the positioning platform 321 is in contact with the front end face of the mounting panel 2. The four-groove nut 35 is tightened at the rear end of the mounting panel 2 to realize the fixation of the elastic component 3.

[0048] The positioning block 4 includes a rectangular block body. A through hole 41 matching the shape of the moving marking rod 51 is provided in the rectangular block body, and the rectangular block body is fixed to the second side plate 13 by screws.

[0049] The through hole 41 is rectangular, and the moving marking rod 51 is rectangular strip-shaped.

[0050] The connecting piece 20 is a cross recessed head screw.

[0052] The mounting bracket further includes two A-type set screws 9, which are respectively installed on both sides of the front end of the horizontal plate 11.

[0053] The mounting bracket further includes two positioning pins 10, which are respectively installed on the mounting panel 2 and used for docking with the positioning sleeve 32 of the chassis.

[0054] The present invention further provides a method for using the above mounting bracket with the function of indicating the docking in place, which specifically includes the following steps:

[0055] Step 1: First, according to the theoretical distance required for docking in place between the mounting panel 2 and the rear mounting plate of the connector on the chassis, determine the position where the chassis docks in place on the mounting bracket. Then, draw a marking line 511 on the moving marking rod 51 and determine the position of the frontmost positioning block 4, so that when the chassis docks in place, the marking line 511 and the front end face of the frontmost positioning block 4 on the second side plate 13 are exactly aligned;

[0056] Step 2: Push the chassis placed on the horizontal plate 11 in the direction of docking with the connector of the mounting panel 2 of the mounting bracket. The rear mounting plate of the chassis contacts the connecting rod 52 of the docking-in-place indicating mechanism 5, and slides the connecting rod 52 and the ejector rod 36 of the elastic component 3 in the docking direction. At the same time, the spring 34 in the elastic component 3 is compressed, and the end of the moving marking rod 51 gradually approaches the end face of the positioning block 4. When the docking between the chassis and the mounting bracket is in place, the marking line 511 and the front end face of the frontmost positioning block 4 on the second side plate 13 are exactly aligned. Then, use two A-type set screws 9 to lock the chassis; (For the schematic diagram of the docking in place between the chassis and the mounting bracket, refer to Figure 8 .)

[0057] Step 3: When the chassis is pulled out, the spring 34 in the elastic component 3 resets, and the ejector rod 36 drives the docking-in-place indicating mechanism 5 to return to the initial position before the chassis is docked.

[0058] The installation positions of the elastic component and the in-place indication mechanism of the present invention are two gap positions between the mounting frame and the chassis connection. One is located at the side gap between the chassis and the mounting frame, and the other is located at the gap between the rear mounting plate of the chassis and the connector mounting panel on the mounting frame. These two gaps exist in the positions after all mounting frames are docked with the chassis equipment and will not cause an increase in the external dimensions of the mounting frame;

[0059] The present invention enables the recognition of whether the chassis and the mounting frame are docked in place at the front end of the mounting frame, avoiding the inconvenience caused by observing the docking status at the top and side of the mounting frame to determine whether it is qualified; the determination of the equipment docking in place can be completed without any extra operations on the machine. The movement of the in-place indication mechanism is realized only during the docking process of the chassis and the mounting frame. It is judged whether to continue pushing the equipment according to the indicated position, ensuring the docking in place of the mounting frame and the equipment, and being convenient for observation.

[0060] During the structural design, the influence of the chassis equipment mounted on the mounting frame and the mounting frame itself on the structural strength of the in-place indication mechanism is fully avoided. During actual use, this structure only bears the load of its own weight under the conditions of aircraft use, making it have high reliability;

[0061] The in-place indication mechanism for docking can be applied to all mounting frame products fixed by type A locking devices, with strong applicability.

[0062] The above content is only the preferred embodiment of the present invention. For those of ordinary skill in the art, many changes can be made in the specific implementation manner and application scope according to the idea of the technical content of the present invention. As long as these changes do not depart from the concept of the present invention, they all fall within the protection scope of this patent.
