Description

Technical Field

[0001] The utility model relates to the field of control handle structures, and specifically to a two-stage control handle. Background Art

[0002] As a key device for a pilot to control the flight direction and perform various flight tasks, the design of a helicopter control handle directly affects the safety and efficiency of flight operations. In the prior art, most helicopter control handles adopt a single-stage design, that is, all control elements such as control switches, buttons, and joysticks are integrated in a compact space. This design effectively reduces the learning cost and improves the operation convenience during the period when the functions of helicopters are relatively simple and the number of control elements is small.

[0003] However, with the rapid development of helicopter technology and the continuous expansion of application fields, the tasks that helicopters need to perform are becoming increasingly complex and diverse, and the functional requirements for the control handle are also increasing accordingly. To meet these requirements, it is necessary to continuously add control elements to the single-stage handle, such as switch buttons, adjustment knobs, and multi-functional joysticks.

[0004] However, too many control elements make the handle interface extremely crowded. When operating, the pilot needs to frequently switch the line of sight, which reduces the operation efficiency and increases the operation burden. At the same time, arranging too many control elements in a limited area results in blurred boundaries of functional areas, making it difficult for the pilot to intuitively identify the specific functions of each control element and easily causing misoperations, posing a threat to flight safety. Moreover, when new control functions need to be added, it is often necessary to completely redesign the handle, increasing the development cost and causing waste of resources.

[0005] In view of this, this application is specifically proposed. Content of the Utility Model

[0006] The purpose of the utility model is to provide a two-stage control handle, which can solve the problems existing in the existing single-stage control handle under the background of complex functions, such as crowded interface, low operation efficiency, increased risk of misoperation, and limited function expansion.

Specific embodiments

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Refer to Figures 1-4 , a two-section control handle, including a handle body, the handle body includes a connecting section 1 and a fixing section 2, and the fixing section 2 is provided at the top of the connecting section 1.

[0026] The connecting section 1 includes a connecting pipe 11, and an installation hole is provided at the bottom of the connecting pipe 11 for connecting with the control console of the helicopter. This is the prior art and will not be elaborated here; a flight operation unit 3 is provided at the top of the connecting pipe 11. The flight operation unit 3 may include a flight panel fixed to the top of the connecting pipe 11, and a flight button assembly is provided on the flight panel for controlling the flight of the helicopter. The specific composition of the flight button assembly can be determined according to actual requirements. The specific structures of the flight panel and the flight button assembly are both prior art and will not be elaborated here.

[0027] The fixed section 2 includes a fixed tube 21. At the top of the fixed tube 21, there is a mission operation unit 4. The mission operation unit 4 may include a mission panel fixed to the top of the fixed tube 21. On the mission panel, there is a mission button assembly for completing the multi-functional missions of the helicopter. The specific composition of the mission button assembly can be determined according to actual requirements. The specific structures of the mission panel and the mission button assembly are both prior arts and will not be elaborated here. The two-stage setting of the flight button assembly and the mission button assembly can reduce the number of control buttons per unit area, make the handle interface clear, and improve the operation efficiency. At the same time, it makes the boundaries between flight and mission clear, enabling the pilot to intuitively identify the specific functions of each control element and avoid misoperation, which poses a threat to flight safety.

[0028] The fixed tube 21 is inserted into the connecting tube 11. A detachable connection mechanism 5 is provided between the connecting tube 11 and the fixed tube 21. When new control functions need to be added, the connecting section 1 or the fixed section 2 for the added control functions can be designed separately, avoiding the need to re-design the handle as a whole, thereby reducing the development cost and saving resources. At the same time, when the connecting tube 11 or the fixed tube 21 is damaged, only the damaged part needs to be replaced, without the need for overall replacement, thus reducing the maintenance cost. The circuit connection between the connecting tube 11 and the fixed tube 21 can be achieved by setting electronic components such as an adapter board in the connecting tube 11. This is a prior art and will not be elaborated here.

[0029] In some embodiments, the detachable connection mechanism 5 includes an annular groove 51 provided at the top of the connecting tube 11. On the middle surface of the fixed tube 21, there are a plurality of sliding grooves 52. In each sliding groove 52, there is a plug-in block 53 that can slide therein. The plug-in block 53 can penetrate the connecting tube 11 and extend into the sliding groove 52. Between the plug-in block 53 and the side wall of the sliding groove 52 away from the connecting tube 11, there is an expansion member 54. The expansion member 54 can be a spring to provide an automatic reset force for the plug-in block 53. In the annular groove 51, there is an adjusting member 6 for controlling the locking and releasing of the fixed tube 21 by the plug-in block 53.

[0030] In some embodiments, a plurality of limiting protrusions are provided on the outer surface of the fixed tube 21, and a plurality of limiting grooves are provided at the top of the connecting tube 11. The limiting protrusions and the limiting grooves are in plug-in fit, which can facilitate the pre-positioning when the fixed tube 21 is inserted into the connecting tube 11. At the same time, after the plug-in is completed, it can improve the fixed limit between the fixed tube 21 and the connecting tube 11 and enhance the stability when the two are connected.

[0031] In some embodiments, the adjusting member 6 includes a rotating ring 61 provided in the annular groove 51. The rotating ring 61 can rotate in the annular groove 51. The rotating ring 61 is provided with a plurality of adjusting units corresponding to the plug-in blocks 53. There is an adjusting opening 62 between adjacent two adjusting units.

[0032] In some embodiments, the adjusting unit includes a fixed seat 63. On one side of the fixed seat 63 close to the connecting pipe 11, there is an adjusting groove 64. An adjusting block 65 is slidably arranged in the adjusting groove 64. The adjusting block 65 is inserted and matched with the sliding groove 52. Between the adjusting block 65 and the side wall of the adjusting groove 64 far from the connecting pipe 11, there is a return spring 66 to provide a restoring force for the adjusting block 65. The elastic coefficient of the return spring 66 can be greater than that of the telescopic member 54 to realize the reset of the adjusting block 65.

[0033] In some embodiments, the protruding side surface of the insertion block 53 on the fixed pipe 21 is an arc surface, which can make the insertion block 53 contract more smoothly when the adjusting block 65 rotates and presses the insertion block 53, thereby improving the adjustment effect.

[0034] In some embodiments, the surface of the rotating ring 61 can be provided with anti-slip patterns to increase the friction between the hand and the rotating ring 61.

[0035] In some embodiments, the outer diameter of the rotating ring 61 is smaller than the outer diameter of the connecting pipe 11 to prevent the rotating ring 61 from protruding from the connecting pipe 11 and affecting the operation of the driver.

[0036] The specific working principle is as follows:

[0037] When it is necessary to connect the connecting section 1 and the fixed section 2, insert the fixed pipe 21 into the connecting pipe 11. At this time, the insertion block 53 automatically extends under the action of the telescopic member 54 and attempts to contact the inner wall of the connecting pipe 11. Rotate the rotating ring 61 to align the adjusting opening 62 with the insertion block 53. At this time, the insertion block 53 is not restricted, so it is inserted into the adjusting opening 62. The adjusting block 65 abuts against the inner wall of the annular groove 51, and the return spring 66 is in a compressed state, realizing the fixed connection between the fixed pipe 21 and the connecting pipe 11.

[0038] When disassembly is required, rotate the rotating ring 61 in the reverse direction. The adjusting block 65 rotates accordingly and presses the insertion block 53. Since the elastic coefficient of the return spring 66 can be greater than that of the telescopic member 54, the adjusting block 65 is inserted into the sliding groove 52 under the elastic action of the return spring 66, and the telescopic member 54 is compressed and deformed. At this time, the insertion block 53 automatically resets and retracts into the sliding groove 52 under the action of the telescopic member 54, thereby allowing the fixed pipe 21 to be pulled out of the connecting pipe 11 and realizing the rapid separation of the two handle sections.

[0039] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
