Description

Technical Field

[0001] This utility model belongs to the field of computer equipment technology, specifically relating to an airborne multi-functional keyboard with a flip function. Background Technology

[0002] With the rapid development of science and technology and the increasing intelligence of airborne equipment, multi-function keyboards, as an important tool for human-computer interaction, have been widely used in airborne devices. However, most existing airborne multi-function keyboards are fixedly installed, typically on the dashboard or below the display. This fixed installation method has the following problems:

[0003] First, the instrument panels of airborne equipment are typically designed to be compact, leaving insufficient space for mounting a control panel or multifunction keyboard. This renders multifunction keyboards unusable in most situations, limiting their application in airborne equipment.

[0004] Secondly, fixed keyboards require operators to adjust their body posture or line of sight, especially in situations with limited space, resulting in poor operational flexibility and affecting the efficiency of human-computer interaction.

[0005] Third, most existing multi-function keyboards do not have flip or tilt functions, and cannot adjust the angle and position of the keyboard according to actual usage needs, which limits their applicability in different scenarios.

[0006] Fourth, because the keyboard's installation position is fixed, adjusting the operating angle may affect the signal transmission between the keyboard and the device, further limiting the keyboard's usability. This is detrimental to the development of human-computer interaction and the intelligence of airborne equipment. Utility Model Content

[0007] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an airborne bracket and multi-functional keyboard with a flip function that is easy to operate, simple in structure, and highly integrated.

[0008] The technical solution adopted to solve the above-mentioned technical problems is as follows: an airborne support with a flipping function, wherein the bracket is provided with a left guide rail and a right guide rail, and both the left and right guide rails are provided with a sliding linkage mechanism and a limiting structure. The limiting structure is used to prevent the sliding linkage mechanism from sliding out of the left and right guide rails. The sliding linkage mechanism consists of one end of a first sliding link and one end of a second sliding link hinged together. The first and second sliding links slide within the left or right guide rail. One end of a third link is hinged to the middle of the outer side of the first sliding link, and the other end of the third link is hinged to the middle of the outer side of the second sliding link. An instrument mounting assembly is provided on the second sliding link. When the two second sliding links slide out of the left and right guide rails from one side, they automatically flip downwards at a certain angle and maintain an inclined state.

[0009] As a preferred technical solution, a groove is provided on the outer side of the second sliding link and between the other end of the third link and one end of the second sliding link, and a telescopic spring positioning pin that matches the groove is provided on the third link.

[0010] As a preferred technical solution, the limiting structure includes a locking block and a limiting block. The locking block is disposed at the other end of the first sliding link, and there are two limiting blocks, which are respectively disposed on the front side of the left guide rail and the right guide rail and match the locking block.

[0011] As a preferred technical solution, the bottom of the third link is provided with a boss. When the second sliding link is completely slid out from the left or right guide rail and is located outside the bracket in an inclined state, the boss is locked on the front side of the bracket base plate.

[0012] As a preferred technical solution, the right guide rail is provided with a main sliding groove and an auxiliary sliding groove for preventing derailment, and the opening direction of the main sliding groove is perpendicular to the opening direction of the auxiliary sliding groove; the structure of the left guide rail is the same as that of the right guide rail; the opening of the main sliding groove of the right guide rail is opposite to that of the main sliding groove of the left guide rail; the inner sides of the first sliding link and the second sliding link are provided with a first protruding ridge that matches the main sliding groove, and the top and bottom of the first sliding link are respectively provided with a second protruding ridge that matches the auxiliary sliding groove.

[0013] As a preferred technical solution, the hinge point between the second sliding link and the other end of the third link is two intersecting circular grooves.

[0014] An airborne multi-function keyboard with a flip function is provided. The multi-function keyboard is mounted on the instrument mounting assembly of the second sliding link of the airborne bracket with the flip function. When the first sliding link and the second sliding link are located in the left or right guide rail, the multi-function keyboard is in a horizontal state above the bracket. When the second sliding link slides completely out of the left or right guide rail and is located outside the bracket in an inclined state, the multi-function keyboard is located on one side of the bracket in an inclined state.

[0015] As a preferred technical solution, a locking mechanism is provided between the multi-function keyboard and the bracket, which is used to lock the multi-function keyboard when it is horizontally positioned above the bracket.

[0016] As a preferred technical solution, the locking mechanism includes an auxiliary puller and a locking platform. The auxiliary puller is hinged to the bottom of the multi-function keyboard, and the locking platform is fixed on the bracket. When the auxiliary puller is in a horizontal position, its tail end is locked onto the locking platform, and when the auxiliary puller is in a vertical position, its tail end is disengaged from the locking platform, which is the unlocked state.

[0017] As a preferred technical solution, the multi-function keyboard has a baffle on the front side, the multi-function keyboard is in a horizontal state, the baffle is stuck on the left guide rail and the right guide rail, the baffle is machined with a pull-out aid groove, and the pull-out aid head has a notch machined on the pull-out aid groove at the corresponding position to secure the pull-out aid.

[0018] The beneficial effects of this utility model are as follows:

[0019] This invention enables the multi-functional keyboard to flip and tilt through a sliding linkage mechanism, thereby retracting the multi-functional keyboard when not in use, saving space on the dashboard, meeting the requirements of a compact layout for airborne equipment, and allowing operators to use the keyboard conveniently without adjusting their body posture, significantly improving the efficiency and comfort of human-computer interaction.

[0020] The second sliding link of this invention has a slot, and the third link has a telescopic spring positioning pin that matches the slot, to ensure that the multi-function keyboard remains stable in the flipped and tilted state and avoid displacement caused by vibration or other external forces.

[0021] This utility model's multi-functional keyboard does not affect its connection with the device during flipping and tilting, ensuring the stability and reliability of signal transmission and avoiding signal interruption problems caused by angle changes.

[0022] The locking mechanism of this invention enables the multi-function keyboard to lock quickly in a horizontal position, ensuring the stability of the onboard equipment during operation and preventing the multi-function keyboard from sliding and affecting the operation of the equipment during movement. The unlocking operation is simple and easy to use.

[0023] This invention, by optimizing the structure of the keyboard connection bracket, not only solves the problems of space limitations and inconvenient operation in the prior art, but also promotes the further development of human-computer interaction technology for airborne equipment, providing better support for the intelligentization of airborne equipment.

[0033] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments, but the present invention is not limited to the following embodiments.

[0034] Example 1

[0035] exist Figure 1 In this embodiment, the airborne support with a flipping function includes a bracket 1, a left guide rail 3, a right guide rail 2, a sliding linkage mechanism, a limiting structure, and a locking mechanism. The bracket 1 connects this invention to the airborne equipment via threaded fasteners. The left guide rail 3 and right guide rail 2, with identical structures, are fixedly installed on the bracket 1 using threaded fasteners. The right guide rail 2 has a main sliding groove 2-2 and an auxiliary sliding groove 2-1 for preventing derailment. The opening direction of the main sliding groove 2-2 is perpendicular to the opening direction of the auxiliary sliding groove 2-1. The openings of the main sliding groove 2-2 of the left guide rail 3 and the main sliding groove 2-2 of the right guide rail 2 are opposite to each other. Both the left guide rail 3 and the right guide rail 2 are equipped with a sliding linkage mechanism and a limiting structure. The limiting structure prevents the sliding linkage mechanism from sliding off the left guide rail 3 and the right guide rail 2, allowing the sliding linkage mechanism to slide along the left guide rail 3 and the right guide rail 2.

When the second sliding link 7 is in a horizontal state, the front end of the third link 6, the third hinge shaft 11, is located in the front slot of the slide groove. When the second sliding link 7 is in an inclined state, the front end of the third link 6, the third hinge shaft 11, is located in the rear slot of the slide groove. The structure of the slot is used to provide the operator with a feel and facilitate the operator to identify changes in state. The bottom of the third link 6 is machined with a boss 6-1. When the second sliding link 7 slides out completely from the left guide rail 3 or the right guide rail 2 and is located outside the bracket 1 in an inclined state, the boss 6-1 is stuck on the front side of the base plate of the bracket 1 to improve stability. A groove 7-2 is machined on the outer side of the second sliding link 7 and between the front end and the rear end of the third link 6. A telescopic spring positioning pin 5 that matches the groove 7-2 is fixedly installed on the third link 6.

[0038] The limiting structure in this embodiment includes a locking block 13 and a limiting block 9. The locking block 13 is fixedly installed at the rear end of the first sliding link 4. There are two limiting blocks 9, which are respectively fixedly installed on the front side of the left guide rail 3 and the right guide rail 2 and match the locking block 13. When the first sliding link 4 slides forward and the locking block 13 is locked on the limiting block 9, the second sliding link 7 is completely disengaged from the guide rail.

[0039] Example 2

[0040] In this embodiment, as Figures 5-6 Example 1: A multi-function keyboard with a flip function is fixedly installed on the sliding linkage mechanism of the airborne bracket with a flip function. The multi-function keyboard 14 has a connecting ear plate machined at the bottom. The multi-function keyboard 14 is fixedly connected to the screw and nut assembly on the second sliding linkage 7 through the connecting ear plate. A locking mechanism is provided between the multi-function keyboard 14 and the bracket 1 for locking when the multi-function keyboard 14 is in a horizontal state above the bracket 1. When the sliding linkage mechanism drives the multi-function keyboard 14 to slide out from the front side of the bracket 1, the multi-function keyboard 14 flips downward and tilts to a tilted state and remains there.

[0041] The locking mechanism of this embodiment includes a puller 16 and a locking platform 17. The puller 16 is hinged to the bottom of the multi-function keyboard 14. The puller 16 is an LRM puller sold on the market. The locking platform 17 is fixedly installed on the bracket 1. When the puller 16 is in a horizontal state, its tail end is locked onto the locking platform 17, which is the locked state. When the puller 16 is in a vertical state, its tail end is disengaged from the locking platform 17, which is the unlocked state.

[0042] A baffle 15 is installed on the front side of the multi-function keyboard 14. The multi-function keyboard 14 is in a horizontal state. The baffle 15 is locked on the left guide rail 3 and the right guide rail 2 to prevent the multi-function keyboard 14 from sliding out from the rear side of the bracket 1. A puller relief groove is machined on the baffle 15. A notch is machined on the puller relief groove at the corresponding position of the head of the puller 16. The notch cooperates with the self-locking structure at the head of the puller 16 to realize the self-locking of the puller.

[0043] The working principle is as follows:

[0044] Initial state: The first sliding link 4 and the second sliding link 7 of the sliding linkage mechanism are located inside the left guide rail 3 and the right guide rail 2. The telescopic spring positioning pin 5 abuts against the outer surface of the second sliding link 7. The puller of the locking mechanism is in a horizontal state, and its tail end is locked on the locking platform 17 on the bracket 1, thus locking the multi-function keyboard 14.

[0045] Flipping Process: When the multi-function keyboard 14 needs to be used, first adjust the puller of the locking mechanism from the horizontal state to the vertical state, so that the tail end of the puller 16 disengages from the slot 17, unlocking the multi-function keyboard 14. The operator holds the puller 16 and pulls the multi-function keyboard 14 forward. The first sliding link 4 and the second sliding link 7 of the sliding linkage mechanism slide in the guide rail. When the second sliding link 7 has completely slid out of the guide rail, the operator places his hand on the front end of the multi-function keyboard 14 and presses it down. The second sliding link 7 drives the multi-function keyboard 14 to flip downward at a certain angle and tilt. When a "click" is heard, the telescopic spring positioning pin 5 automatically slides into the slot 7-2, and the tilt is in place.

[0046] Tilt state: The two intersecting circular sliding grooves of the sliding linkage mechanism allow the third link 6 to maintain a hinged relationship during tilting, ensuring the flexibility and stability of the structure. The boss 6-1 at the bottom of the third link 6 is locked on the front side of the bracket 1 base plate to ensure the stability of the keyboard in the tilt state.

[0047] Reset Process: When it is necessary to restore the multi-function keyboard 14 to a horizontal position, pull the telescopic spring positioning pin 5 outward to slide it out of the slot 7-2. Move the multi-function keyboard 14 upward, causing it and the second sliding link 7 to flip upward and reach a horizontal position. Push the multi-function keyboard 14 backward, and the second sliding link 7 re-enters the guide rail. When the front baffle 15 of the multi-function keyboard 14 is engaged with the front ends of the left guide rail 3 and the right guide rail 2, the keyboard is reset in place. The locking mechanism's puller 16 is then restored to a horizontal position. The head of the puller 16 engages with the notch in the puller clearance slot of the multi-function keyboard 14, and the tail engages with the slot 17, ensuring the stability of the multi-function keyboard 14 in a horizontal position. Figure 7 , 8 .

[0048] The internal signal connection of the multi-function keyboard 14 remains stable during flipping and tilting, ensuring uninterrupted signal transmission. The sliding linkage mechanism avoids signal interruption caused by angle changes, meeting the needs of airborne equipment in different operating scenarios while ensuring structural stability and reliable signal transmission.
