Description

Technical Field

[0001] This invention belongs to the field of aerospace manufacturing technology, and in particular relates to a foot pedal displacement and detection device and its installation, disassembly and use methods. Background Technology

[0002] The rudder pedals are a crucial component of an aircraft's flight control system. With the rudder unlocked, shifting the pedals causes rudder deflection; with the rudder locked, shifting the pedals causes nose wheel deflection. During ground testing, to achieve rudder or nose wheel deflection, manual force is applied to the pedals using the legs and feet to manually shift them. As the pedals shift, technical specifications require stabilizing them within a specific range of displacement (determined by the projected displacement of a small plumb bob installed at the center of the pedal axle). This specific displacement range is then used to observe and detect rudder or nose wheel deflection. However, during pedal shifting, the reverse force from the rudder's lower spring lever prevents the user's foot pressure from being consistently and stably applied to the pedals, leading to instability within the specified displacement range and affecting the indicated rudder or nose wheel turning angle. Therefore, manually applying force to stabilize the pedals to a specific displacement value is difficult, time-consuming, labor-intensive, and yields poor results. Summary of the Invention

[0003] The technical problem solved by this invention: This invention overcomes the shortcomings of the prior art and provides a foot pedal displacement and shift detection device and its installation, disassembly, and use method that is simple to operate, requires little labor intensity, is convenient to assemble and disassemble, and has good implementation effect.

[0004] The technical solution of this invention:

[0005] On the one hand, the present invention provides a foot pedal displacement and displacement detection device, which is installed in the groove hole on the U-shaped side of the seat guide rail and can be locked to the cabin floor by the seat guide rail during use;

[0006] The device includes a detection device frame 01, a connecting component 02, an adapter 03, two support sleeves 04, a screw 05, a bushing 06, a right-angle hand-cranked angler 07, a scale 08, and a pointer 09.

[0007] Both the connecting component 02 and the adapter 03 are fixedly connected to the frame 01 by screws;

[0008] The connecting component 02 and the adapter 03 are screwed together; one end of the adapter 03 is fixedly connected to the bushing 06.

[0009] The support sleeve 04 is screwed onto the frame 01 at two points;

[0010] One end of the screw 05 is fitted with the support sleeve 04 through a shaft hole to rotate under the support of the support sleeve 04. The other end of the screw 05 is fitted with the shaft on the right-angle hand crank 07 and fixed with a cylindrical pin. The middle cylindrical rod of the screw 05 is fitted with the shaft sleeve 06 through a trapezoidal thread.

[0011] The bushing 06 has two round holes on its side for fixing the pointer 09;

[0012] The scale 08 is fixed to the side of the frame 1.

[0013] Furthermore, the skeleton 01 includes: main skeleton 11, slide rail fixing support 12, scale sliders 13a and 13b, corner fixing plate 14, and two bushing fixing plates 15;

[0014] The detection device frame 01 is a square aluminum alloy component, and the main frame 11 is an aluminum square tube used to support the basic structure of the device. The slide rail fixing support 12 adopts an L-shaped structure, with one end welded to the main frame 11 and the other end having two slotted holes that can be matched with the circular holes of the guide slide rail 10a on the aircraft floor. The scale sliders 13a and 13b have the same structure, with their bottom surfaces welded to the side walls of the main frame 11, and both have slots for inserting the scale 08. The scale slider 13a has a circular hole on its front side that matches the knurled cylindrical head set screw for pressing and fixing the movement of the scale. The corner fixing plate 14 is welded to the front side of the main frame 11 on one side and has four circular holes on the other side for use with the right-angle hand-cranked corner 07. The bottom surfaces of the two bushing fixing plates 15 are welded to the front side of the main frame 11 and have four circular holes on one side for use with the support sleeve 04. The main frame 11 has elongated slotted through holes 16 on both side walls, allowing the adapter 03 to move back and forth within these through holes.

[0015] Furthermore, the connecting assembly 02 includes a support 21, a positioning assembly 22, and a handle 23; the positioning assembly 22 includes a positioning seat 221, a connector 222, two positioning rods 223, a positioning shaft 224, two springs 225, two sets of flat washers 226 and a positioning pin 227, a set of washers 228 and a nut 229;

[0016] The connecting component 02 is screwed together with the adapter 03 via the support 21 and the internal hexagon screws; the adapter 03 reciprocates within the elongated slot-shaped through hole 16 guided by two hinge shafts;

[0017] The positioning component 22 has two slotted holes that mate with the two round holes of the support 21, and the two are connected by a stepped screw. The handle 23 is L-shaped and is a pin that passes through the connector 222 and the positioning seat 221, and is fixed to the end face of the connector 222 by a cotter pin.

[0018] The positioning base 221 has two positioning rod holes, through which the positioning rod 223 passes and is limited by the positioning pin 227; a spring 225 is mounted on the positioning rod 223.

[0019] It can realize the separation and return of the connector 222 and the positioning seat 221; the connector 222 is provided with a positioning shaft hole, and the positioning shaft 224 is fixedly connected by the washer 228 and the nut 229; the size of the smooth rod of the positioning shaft 224 is matched with the pedal shaft 10c, and the connection between the connecting component 02 and the pedal shaft is realized by inserting the positioning shaft 224 into the pedal shaft 10c.

[0020] Furthermore, the adapter 03 is a frame structure, made of three plates welded together. One end of it is fixedly connected to the bushing 06. The rotation of the screw 05 causes the bushing 06 to reciprocate linearly on the screw 05, which in turn drives the adapter 03 to move forward or backward.

[0021] Furthermore, the scale 08 has a 0 mark in the middle and a maximum of 20cm at both ends, used to indicate the amount of forward or backward movement of the pedal; the pointer 09 has two countersunk holes, which are fixedly connected to the side holes of the bushing 06.

[0022] On the other hand, the present invention provides an installation method for a foot pedal displacement and detection device, the installation method being used to install the device, the installation method comprising:

[0023] During installation, the foot pedal displacement and displacement detection device is fixed to the guide rail 10a on the aircraft floor by the slide rail fixing bracket 12. Then, the handle 23 in the connecting assembly 02 is used to push the connector 222 away in parallel, thereby driving the positioning shaft 224 to move in parallel. The upper and lower positions of the positioning seat 221 and the support 21 are adjusted so that the positioning shaft 224 is aligned with the inner hole of the foot pedal shaft 10c. The positioning shaft 224 is inserted into the foot pedal shaft 10c. At this time, the handle 23 is released, and the connector 222 is pulled back to its original position under the action of the spring 225 in the positioning assembly 22, so that the connecting assembly 02 and the foot pedal 10b fit tightly together.

[0024] On the other hand, the present invention provides a method of using a foot pedal displacement and detection device, the method of using the device being installed, the method of using the device comprising:

[0025] With the pedal in the neutral position, adjust the scale 08 by moving it back and forth to the positions of the scale sliders 13a and 13b, so that the tip of the pointer 09 is aligned with the "0" mark on the scale 08. Then, use the knurled cylindrical head set screw to tighten the scale 08 and lock it in a fixed position.

[0026] In order to move the pedal 10b forward, the Z-shaped handle on the right-angle hand crank 07 is rotated clockwise, which drives the screw 05 to rotate, causing the adapter 03 to move forward. The adapter 03 drives the positioning shaft 224 to move forward, and the positioning shaft 224 pushes the pedal 10b forward.

[0027] To move pedal 10b backward, rotate the Z-shaped handle on the right-angle hand crank 07 counterclockwise to drive screw 05 to rotate, causing adapter 03 to move backward. Adapter 03 drives positioning shaft 224 to move backward, and positioning shaft 224 pulls pedal 10b backward.

[0028] During the forward or backward movement of pedal 10b, scale 08 remains stationary, while pointer 09 moves forward or backward with adapter 03. The position of the tip of pointer 09 at the mark on scale 08 represents the displacement of pedal 10b.

[0029] On the other hand, the present invention provides a method for disassembling a foot pedal displacement and displacement detection device, the disassembly method being used to disassemble the device, the disassembly method comprising:

[0030] During disassembly, by operating the handle 23 inside the connecting assembly 02 to push away the connector 222, the positioning shaft 224 is disengaged from the pedal shaft 10c. The upper and lower positions of the positioning seat 221 and the support 21 are adjusted so that the positioning shaft 224 is offset from the inner hole of the pedal shaft 10c. The handle 23 is released, and the positioning assembly 22 pulls the connector 222 back to its original position under the action of the spring 225, so that the connecting assembly 02 is disengaged from the pedal 10b. The connection between the slide rail fixing support 12 and the guide slide rail 10a is disassembled, and the pedal displacement and displacement detection device is quickly removed as a whole.

[0031] This invention provides a foot pedal displacement and detection device. Its overall frame is welded from aluminum plates, offering good manufacturability and load-bearing capacity. The connecting component has two oblong holes for vertical adjustment of the positioning shaft, and a spring and handle within the positioning component allow for horizontal adjustment of the positioning shaft, improving the accuracy of the alignment between the positioning shaft and the foot pedal shaft hole and the flexibility of the positioning component's assembly and disassembly. The screw, made of 45# material with a trapezoidal thread, rotates to move the adapter forward or backward, thereby driving the positioning shaft to achieve reciprocating linear motion, improving the screw's load-bearing capacity and linear motion flexibility. The scale, fixed in a slider on the side of the detection device frame, can slide back and forth. In conjunction with the pointer, it allows for quick positioning of the foot pedal displacement, improving the convenience and intuitiveness of displacement detection. The foot pedal displacement and detection device is rationally laid out and connected to the oblong holes of the guide rail on the floor using screws, making assembly and disassembly convenient and highly adjustable.

Figure 11 (As shown), ruler 08, pointer 09.

[0048] The detection device frame 01 is a square aluminum alloy component, assembled and welded from aluminum square tubes and aluminum plates. The aluminum square tubes are made of 6061-T5 material, and all aluminum plates are made of 6063-T6 material. The welds between the aluminum plates are strong, the surface is smooth, and it is lightweight. Figure 4 As shown, the main frame 11 is an aluminum square tube, used as the basic structure to support the device; the slide rail fixing support 12 is a 6063-T6 aluminum plate with an L-shaped structure, one end of which is welded to the main frame 11, and the other end has two slotted holes that can mate with the circular holes of the guide slide rail 10a on the aircraft floor, such as... Figure 2As shown; scale sliders 13a and 13b have the same structure, with their bottom surfaces welded to the side walls of the main frame 11, and both have slots for inserting the scale 08; scale slider 13a has a round hole on its front side, which cooperates with the knurled cylindrical head set screw BZ-01 to press and fix the movement of the scale; the corner fixing plate 14 is made of 6063-T6 aluminum plate, one side is welded to the front side of the main frame 11, and the other side has 4 round holes for use with the right-angle hand-cranked corner 07; the two bushing fixing plates 15 are also made of 6063-T6 aluminum plate, with their bottom surfaces welded to the front side of the main frame 11, and one side has 4 round holes for use with the support sleeve 04. The main frame 11 has elongated slotted through holes 16 on both side walls, allowing the adapter 03 to move back and forth within these through holes.

[0049] like Figure 5 As shown, the connecting component 02 includes a support 21, a positioning component 22, and a handle 23; the positioning component 22 includes a positioning seat 221, a connector 222, two positioning rods 223, a positioning shaft 224, two springs 225, two sets of washers 226 and a positioning pin 227, one set of washers 228 and a nut 229.

[0050] The connecting component 02 is screwed together with the adapter 03 via the support 21 and the socket head cap screw BZ-03; the adapter 03 reciprocates within the elongated slot-shaped through hole 16 guided by the two hinge shafts BZ-02.

[0051] The positioning component 22 has two slotted holes that mate with the two round holes of the support 21, and the two are connected by a stepped screw BZ-04. The handle 23 is L-shaped.

[0052] like Figure 6 As shown, the original pin body passes through the connector 222 and the positioning seat 221, and is fixed to the end face of the connector 222 by the cotter pin BZ-06.

[0053] The positioning seat 221 is provided with two positioning rod holes, through which the positioning rod 223 passes and is limited by the positioning pin 227; a spring 225 is installed on the positioning rod 223.

[0054] It can realize the separation and return of the connector 222 and the positioning seat 221; the connector 222 is provided with a positioning shaft hole, and the positioning shaft 224 is fixedly connected by the washer 228 and the nut 229; the size of the positioning shaft 224 is matched with the pedal shaft 10c, and the connection between the connecting component 02 and the pedal shaft is realized by inserting the positioning shaft 224 into the pedal shaft 10c.

[0055] like Figure 7As shown, the adapter 03 is a frame structure, which is welded from three plates. One end of it is fixed to the bushing 06. The screw 05 rotates, causing the bushing 06 to reciprocate linearly on the screw 05, which drives the adapter 03 to move forward or backward.

[0056] like Figure 8 As shown, the support sleeve 04 is made of 2A12-T4 material and supports the screw 05 in a two-point manner to perform repeated rotational movements.

[0057] like Figure 9 As shown, the screw 05 is a long cylindrical rod, using a 45-WHR- The material is 465mm in length and has an inner diameter at one end. A 40mm long hole is connected to the shaft on the right-angle hand crank 07 by a cylindrical pin BZ-08. The middle cylindrical rod is provided with a Tr30×6 trapezoidal thread, which is connected to the bushing 06 by a trapezoidal thread. The other end is connected to the support sleeve 04 by a shaft hole, so that it can rotate under the support of the support sleeve 04.

[0060] like Figure 13 As shown, the pointer 09 has two countersunk holes, which are fixedly connected to the side holes of the bushing 06.

[0061] The foot pedal displacement and detection device is installed in the groove-shaped hole on the U-shaped side of the seat guide rail. The device can be locked to the cabin floor via the seat guide rail during use.

[0062] In particular, the pedal displacement and detection device is threaded or pin-type.

[0063] Based on the requirements of ergonomics and ease of operation, the shapes of each component in the detection device were rationally designed. While ensuring strength requirements, additional lightening holes were added, and the edges of each component were required to be smoothed and rounded. During operation, the foot pedal displacement and detection device is fixed to the guide rail 10a on the aircraft floor via the slide rail fixing support 12. Then, the handle 23 within the connecting assembly 02 is used to push the connecting piece 222 away, thereby causing the positioning shaft 224 to shift parallel. The vertical positions of the positioning seat 221 and the support 21 are adjusted so that the positioning shaft 224 is aligned with the inner hole of the foot pedal shaft 10c. The positioning shaft 224 is then inserted into the foot pedal shaft 10c. At this point, the handle 23 is released, and the connecting piece 222 is pulled back to its original position by the spring 225 within the positioning assembly 22, achieving a tight fit between the connecting assembly 02 and the foot pedal 10b. When not in use, by operating the handle 23 inside the connecting assembly 02 to push away the connecting piece 222, the positioning shaft 224 is disengaged from the pedal shaft 10c. The upper and lower positions of the positioning seat 221 and the support 21 are adjusted so that the positioning shaft 224 is offset from the inner hole of the pedal shaft 10c. The handle 23 is released, and the positioning assembly 22 pulls the connecting piece 222 back to its original position under the action of the spring 225, so that the connecting assembly 02 is disengaged from the pedal 10b. The connection between the slide rail fixing support 12 and the guide slide rail 10a is disassembled, and the pedal displacement and displacement detection device is quickly removed as a whole.

[0064] The present invention provides a detailed description of a foot pedal displacement and detection device in conjunction with the accompanying drawings:

[0065] A foot pedal displacement and displacement detection device is provided, including a detection device frame 01, a connecting component 02, an adapter 03, two support sleeves 04, a screw 05, a bushing 06, a right-angle hand-cranked corner 07, a scale 08, and a pointer 09.

[0066] The detection device frame 01 is a square aluminum alloy component, spliced ​​and welded from aluminum square tubes and various aluminum plates. The aluminum square tubes are made of 6061-T5 material, and the aluminum plates are all made of 6063-T6 material. The welds between the aluminum plates are strong, the surfaces are smooth, and it is lightweight. The main frame 11 is an aluminum square tube, used to support the basic structure of the device. The slide rail fixing support 12 is a 6063-T6 aluminum plate with an L-shaped structure. One end is welded to the main frame 11, and the other end has two slotted holes that can mate with the circular holes of the guide slide rail 10a on the aircraft floor. The scale sliders 13a and 13b have similar structures. Similarly, the bottom surface of the main frame 11 is welded to the side wall, and both have slots for inserting the scale 08; the scale slider 13a has a round hole on the front, which cooperates with the knurled cylindrical head set screw BZ-01 to press and fix the movement of the scale; the corner fixing plate 14 is made of 6063-T6 aluminum plate, one side is welded to the front of the main frame 11, and the other side has 4 round holes for use with the right-angle hand-cranked corner 07; the two bushing fixing plates 15 are made of 6063-T6 aluminum plate, the bottom surface is welded to the front of the main frame 11, and the other side has 4 round holes for use with the support sleeve 04. The two side walls of the main frame 11 have elongated slotted through holes 16, which allow the adapter 03 to move back and forth within the through holes.

[0067] The foot pedal displacement and detection device is installed in the groove-shaped hole on the U-shaped side of the seat guide rail. The device can be locked to the cabin floor via the seat guide rail during use.

[0068] In particular, the pedal displacement and detection device is threaded or pin-type.

[0069] Based on the requirements of human-machine interface and ease of operation, the shape of each component in the testing device was reasonably designed. While ensuring the strength requirements, the weight-reducing holes were reasonably increased, and the edges and corners of each component were required to be polished smooth and rounded.

[0070] During operation, the foot pedal displacement and displacement detection device is fixed to the guide rail 10a on the aircraft floor via the slide rail fixing support 12. Then, the handle 23 in the connecting assembly 02 is used to push the connecting piece 222 away in parallel, thereby driving the positioning shaft 224 to move in parallel. The vertical position of the positioning seat 221 and the support 21 is adjusted so that the positioning shaft 224 is aligned with the inner hole of the foot pedal shaft 10c. The positioning shaft 224 is then inserted into the foot pedal shaft 10c. At this time, the handle 23 is released, and the connecting piece 222 is pulled back to its original position under the action of the spring 225 in the positioning assembly 22, so that the connecting assembly 02 and the foot pedal 10b fit tightly together. In the neutral position of the foot pedal, the position of the scale 08 on the scale sliders 13a and 13b is adjusted by moving the scale 08 back and forth so that the tip of the pointer 09 is aligned with the "0" mark on the scale 08. Then, the knurled cylindrical head set screw BZ-01 is used to tighten the scale 08, locking the scale 08 in a fixed position. To move pedal 10b forward, rotate the Z-shaped handle on the right-angle hand crank 07 clockwise, driving screw 05 to rotate, causing adapter 03 to move forward. Adapter 03 then moves positioning shaft 224 forward, which in turn pushes pedal 10b forward. To move pedal 10b backward, rotate the Z-shaped handle on the right-angle hand crank 07 counterclockwise, driving screw 05 to rotate, causing adapter 03 to move backward. Adapter 03 then moves positioning shaft 224 backward, which in turn pulls pedal 10b backward. During the forward or backward movement of pedal 10b, scale 08 remains stationary, while pointer 09 moves forward or backward with adapter 03. The position of the tip of pointer 09 at the mark on scale 08 indicates the displacement of pedal 10b.

[0071] When not in use, by operating the handle 23 inside the connecting assembly 02 to push away the connecting piece 222, the positioning shaft 224 is disengaged from the pedal shaft 10c. The upper and lower positions of the positioning seat 221 and the support 21 are adjusted so that the positioning shaft 224 is offset from the inner hole of the pedal shaft 10c. The handle 23 is released, and the positioning assembly 22 pulls the connecting piece 222 back to its original position under the action of the spring 225, so that the connecting assembly 02 is disengaged from the pedal 10b. The connection between the slide rail fixing support 12 and the guide slide rail 10a is disassembled, and the pedal displacement and displacement detection device is quickly removed as a whole.
