BRIEF DESCRIPTION OF THE DRAWINGS
[0009] Figure 1 It is a schematic diagram of the structure of the present invention (decomposed state).
[0010] Figure 2 It is a structural schematic diagram of the present invention (assembled state). Implementation
[0011] The present invention is further described in detail below by means of specific embodiments in combination with the accompanying drawings. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention. In addition, the technical features involved in each embodiment of the present invention described below can be combined with each other as long as they do not conflict with each other.
[0012] See also Figure 1 and Figure 2 , the figure shows a hand-pinch type airborne control handle structure, which replaces the existing pull-type airborne control handle.
[0013] The hand-pinch type airborne control handle structure includes: a handle vertical outer axis 1, a handle vertical outer cylinder 2, a handle vertical inner axis 3, a handle hand-pinch portion 4, a handle grip portion 5, a handle execution portion 6, a handle compression spring 7, etc.
[0014] The handle vertical outer shaft 1 and the handle vertical outer cylinder 2 are arranged up and down and fixedly connected. The handle vertical outer shaft 1 is on the top, and the handle vertical outer cylinder 2 is on the bottom. The handle vertical inner shaft 3 is inside the handle vertical outer shaft 1 and the handle vertical outer cylinder 2 respectively. The handle vertical inner shaft 3 and the handle vertical outer shaft 1 form a sliding pair.
[0015] The vertical outer shaft 1 of the handle has an outer shaft guide groove 11 extending vertically. The outer shaft guide groove 11 has an outer shaft guide pin 12 extending horizontally inside. The outer shaft guide pin 12 can be displaced up and down along the outer shaft guide groove 11. The outer shaft guide pin 12 is respectively fixedly connected to the upper end of the vertical inner shaft 3 of the handle and the handle hand-grip portion 4 surrounding the outer periphery of the vertical outer shaft 1 of the handle. That is, the outer shaft guide pin 12, the upper end of the vertical inner shaft 3 of the handle, and the handle hand-grip portion 4 constitute a whole and act synchronously. Preferably, the handle hand-grip portion 4 can be selected as a sleeve component.
[0016] The upper end of the handle vertical outer shaft 1 is fixedly connected to the handle gripping portion 5. The upper end of the handle vertical outer shaft 1 can be fixedly connected to the handle gripping portion 5 by a screw.
[0017] The handle vertical outer cylinder 2 has an outer cylinder guide groove 21 extending vertically. An outer cylinder guide pin 22 extending horizontally is arranged inside the outer cylinder guide groove 21. The outer cylinder guide pin 22 can be displaced up and down along the outer cylinder guide groove 21. The outer cylinder guide pin 22 is respectively fixedly connected to the lower end of the handle vertical inner shaft 3 and the handle actuator 6 outside the handle vertical inner shaft 3. That is, the outer cylinder guide pin 22, the lower end of the handle vertical inner shaft 3, and the handle actuator 6 constitute a whole and act synchronously.
[0018] The handle compression spring 7 surrounds the handle vertical outer cylinder 2 and the handle vertical inner shaft 3. The upper end of the handle compression spring 7 is a fixed end, and the lower end of the handle compression spring 7 is a movable end. The handle compression spring 7 is in a compressed state. The handle compression spring 7 applies a downward force to the handle vertical inner shaft 3, so that the outer cylinder guide pin 22 is at the lower limit position of the outer cylinder guide groove 21 and the outer shaft guide pin 12 is at the lower limit position of the outer shaft guide groove 11 when there is no external force.
[0019] Preferably, the outer diameter of the lower end of the handle vertical inner shaft 3 is larger than the outer diameter of the handle compression spring 7 section in the handle vertical inner shaft 3. The handle compression spring 7 is above the lower end of the handle vertical inner shaft 3. The lower end of the handle compression spring 7 abuts against the lower end of the handle vertical inner shaft 3. The handle vertical outer cylinder 2 has an outer cylinder positioning boss above the handle compression spring 7. The upper end of the handle compression spring 7 abuts against the outer cylinder positioning boss. In this way, the positioning of the handle compression spring 7 is achieved.
[0020] Preferably, the handle actuator 6 includes: a toothed structure formed on the outer cylinder guide pin 22 .
[0021] The working principle of the hand-pinch type airborne control handle structure is as follows: the handle compression spring 7 is in a compressed state. The handle compression spring 7 applies a downward force to the handle vertical inner shaft 3, so that the outer cylinder guide pin 22 is at the lower limit position of the outer cylinder guide groove 21 and the outer shaft guide pin 12 is at the lower limit position of the outer shaft guide groove 11 in the absence of external force. When the pilot pinches the handle hand-pinch portion 4 upward with his hand, an upward force is applied to the handle hand-pinch portion 4, and the upward force is greater than the downward force of the handle compression spring 7, thereby the handle hand-pinch portion 4 moves upward and the handle hand-pinch portion 4 drives the handle vertical inner shaft 3 to move upward through the outer shaft guide pin 12, and at the same time, the handle vertical inner shaft 3 drives the handle actuator 6 to move upward through the outer cylinder guide pin 22, and then the handle actuator 6 can drive the corresponding transmission component in the control system. During this period, the overall length of the airborne control handle mechanism does not increase, that is, it does not occupy additional activity space, which is convenient for pilot operation.
[0022] The hand-pinch type airborne control handle structure is an optimization of the existing pull-type handle structure. The hand-pinch control can reduce the force required by the pilot when operating the handle, and can also reduce the movement stroke of the pilot's hand when operating the handle, effectively improving the human-machine performance of the cockpit.
[0023] The above only expresses the implementation mode of the present invention, and its description is relatively specific and detailed, but it cannot be understood as limiting the scope of the invention patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be based on the attached claims.
