Description

Technical Field

[0001] This utility model relates to the field of aircraft simulation equipment technology, specifically an aircraft pedal simulation device. Background Technology

[0002] With the rapid development of the modern civil aviation industry, there is a severe shortage of civil aircraft maintenance personnel and pilots. Consequently, the civil aviation talent training industry is booming, and corresponding training equipment has emerged. Foot pedals, as an important component of the aircraft cockpit, appear in various forms in relevant training institutions.

[0003] Currently, most training institutions use simulation equipment that displays images on a computer monitor and uses simulation software with a mouse to operate the pedals. This simulation method cannot provide a realistic cockpit environment, nor can it allow users to feel the pedal operation, the direction and magnitude of the pedal force, thus failing to achieve a good learning effect. Furthermore, existing physical pedals cannot effectively adjust the default tilt angle and pedal resistance, and the maximum pedal range is inconvenient to adjust, making them less adaptable to various usage scenarios and requiring improvement in practicality.

[0004] In view of this, we propose an aircraft foot pedal simulation device. Utility Model Content

[0005] The purpose of this invention is to provide an aircraft pedal simulation device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An aircraft pedal simulation device includes a base plate, a column fixedly mounted on the top of one end of the base plate, and a pedal hinged to the other end of the base plate. Two sets of the base plate and pedal are provided, with two sets of columns on each set of the base plate. A movable component is provided on the base plate, the movable component comprising:

[0008] A horizontal axis is fixedly installed between the tops of the two sets of columns. A rotating block is rotatably installed on the outside of the horizontal axis through a bearing. One end of a chain is hinged to one end of the pedal near the column.

[0009] The chain has a U-shaped block hinged to the other end. The outer wall of the U-shaped block and the inner wall of the rotating block are both fixedly mounted with rack plates, and the two sets of rack plates mesh with each other. The U-shaped block is fitted with a screw inside. The rack plate on the rotating block has a through slot. The screw passes through the through slot and is threaded into a threaded plate. The threaded plate slides against the inside of the rotating block.

[0010] A fixed frame is fixedly installed on the rotating block. The other end of the fixed frame is snapped with the top of a tension spring. A threaded block is fixedly installed on the outside of the bottom end of the column. A bolt is threaded inside the threaded block. The top of the bolt is snapped with the bottom end of the tension spring. A nut is also threaded on the bolt.

[0011] In a further embodiment, the horizontal axis is provided with two sets, and the bearings on each set of the horizontal axis are provided with two sets, which makes the rotation of the rotating block more stable and reduces friction.

[0012] In a further embodiment, the pedal is tilted when no external force is applied.

[0013] In a further embodiment, the base plate is further provided with an auxiliary component, which includes a base block. The base block is fixedly installed on the top of the base plate, and a slide rod is slidably installed inside the base block. A disc is fixedly installed at one end of the slide rod, and a retaining spring is sleeved on the outside of the slide rod. One end of the retaining spring is fixedly installed on the outer wall of the disc, and the other end of the retaining spring is fixedly installed on the outer wall of an annular washer sleeved on the outside of the slide rod. A rotating rod is fixedly installed at the other end of the slide rod, and a stop bar is fixedly installed at the other end of the rotating rod.

[0014] In a further embodiment, a limiting rod is fixedly installed on the side of the rotating rod near the stop bar, and a limiting groove is formed on the bottom block. The circular motion trajectory of the limiting rod intersects with the limiting groove, and the outer diameter of the limiting rod is adapted to the inner diameter of the limiting groove, so that the limiting rod can smoothly enter the limiting groove.

[0015] In a further embodiment, the base plate of a single set includes two sets of components: a base block, a sliding rod, a disc, a contact spring, a rotating rod, a stop rod, and a limiting rod. Both sets of components are mirror images of the vertical center line of the pedal, positioned at both ends of the pedal. The base block of a single set has multiple sets of limiting grooves, which are arranged in an equally spaced circular array with the center of the circular cross-section of the sliding rod as the array center, thus better determining the maximum pedaling range.

[0016] In a further embodiment, a support block is fixedly installed at the top of the end of the base plate away from the column, and the top of the support block is provided with an anti-slip protrusion to prevent the practitioner's foot from slipping when stepping on the pedal.

[0017] Compared with the prior art, this utility model provides an aircraft pedal simulation device, which has the following features:

[0018] Beneficial effects:

[0019] 1. This aircraft pedal simulation device, in order to better adjust the default tilt angle and pedal resistance, uses a moving component, along with a threaded plate and screw, to disengage the rack plate on the U-shaped block and the rotating block. When the chain is pulled upward, the pedal tilt angle increases, causing the U-shaped block to move forward a target distance. The screw can move inside the through slot, allowing the two rack plates to re-engage. Tightening the screw on the threaded plate adjusts the default tilt angle of the pedal. The height of the bolt tip decreases, and after the tension spring is engaged, the fixing frame keeps the tension spring in a stretched state, applying a default tension force to the rotating block. When the user steps on the pedal, the tension spring is further stretched. By changing the default stretching state of the tension spring, different resistances are experienced when stepping on the pedal, resulting in different pedaling sensations. The support block and anti-slip protrusions prevent the user's foot from slipping when stepping on the pedal.

[0020] 2. This aircraft pedal simulation device incorporates auxiliary components to better determine the maximum pedal depressing range. When the rotating rod is pulled, it causes the sliding rod to slide outward within the base block, resulting in a synchronous and unidirectional movement of the disc. This compresses the spring and simultaneously disengages the limiting rod from its current limiting groove. Rotating the rotating rod towards the bottom of the base block then causes the stop lever to rotate synchronously, lowering its height. Upon reaching the target position, releasing the rotating rod allows the limiting rod to re-enter the target limiting groove, restoring the spring's deformation and fixing the stop lever's current position. This increases the maximum pedal depressing range for subsequent pedal presses. Conversely, rotating the rotating rod in the opposite direction increases the stop lever's height, reducing the maximum pedal depressing range for subsequent pedal presses. This adaptability to various application scenarios enhances the practicality of the simulation device. Attached Figure Description

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

It is primarily used to better describe this application and its embodiments, and is not intended to limit the indicated device, element, or component to having a specific orientation, or to construct and operate in a specific orientation. Furthermore, the term "above" may also be used in certain circumstances to indicate a dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application according to the specific circumstances.

[0034] Please see Figures 1-7 This utility model provides a technical solution:

[0035] An aircraft pedal simulation device includes a base plate 1, a column 2 fixedly installed on the top of one end of the base plate 1, and a pedal 3 hinged to the other end of the base plate 1. The base plate 1 and the pedal 3 are provided in two sets. The column 2 on each set of the base plate 1 is provided in two sets. In addition, the pedal 3 is tilted when no external force is applied.

[0036] In one embodiment of this utility model, a movable component 6 is provided on the base plate 1. The movable component 6 includes a horizontal shaft 61. The horizontal shaft 61 is fixedly installed between the top ends of two sets of uprights 2. A rotating block 63 is rotatably installed on the outside of the horizontal shaft 61 through bearings 62. In addition, there are two sets of horizontal shafts 61, and two sets of bearings 62 are provided on each set of horizontal shafts 61, so that the rotating block 63 rotates more stably and reduces friction. One end of a chain 64 is hinged to one end of the pedal 3 near the upright 2, and a U-shaped block 65 is hinged to the other end of the chain 64. A rack plate 66 is fixedly installed on the outer wall of the U-shaped block 65 and the inner wall of the rotating block 63. The rack plates 66 mesh with each other, and the U-shaped block 65 is fitted with a screw 67. The rack plate 66 on the rotating block 63 has a through slot 68. The screw 67 passes through the through slot 68 and is threaded into the threaded plate 69. The threaded plate 69 slides against the inside of the rotating block 63. One end of the fixing bracket 610 is fixedly installed on the rotating block 63. The other end of the fixing bracket 610 is snapped with the top end of the tension spring 611. The bottom end of the column 2 is fixedly installed with a threaded block 612. The threaded block 612 is threaded with a bolt 613. The top end of the bolt 613 is snapped with the bottom end of the tension spring 611. The bolt 613 is also threaded with a nut 614.

[0037] In this embodiment, the screw 67 on the threaded plate 69 serves to fasten the U-shaped block 65 and the rack plate 66 on the rotating block 63. After loosening the screw 67, the pressure originally applied by the screw 67 disappears, causing the rack plate 66 on the U-shaped block 65 and the rotating block 63 to disengage. At this time, relative movement can occur between the U-shaped block 65 and the rotating block 63. When the chain 64 is pulled upward, since one end of the chain 64 is hinged to the end of the pedal 3 near the column 2 and the other end is hinged to the U-shaped block 65, the pulling force is transmitted to the U-shaped block 65 through the chain 64, causing the U-shaped block 65 to move forward. During the movement of the U-shaped block 65, the screw 67 inside slides in the through groove 68 opened in the rack plate 66 on the rotating block 63. The through slot 68 provides space for the movement of the screw 67. The movement of the U-shaped block 65 changes the position of the chain 64 connected to the pedal 3, thereby increasing the tilt angle of the pedal 3. When the U-shaped block 65 moves to the target distance, that is, after reaching the required tilt angle of the pedal 3, the two rack plates 66 on the U-shaped block 65 and the rotating block 63 re-engage. Then, the screw 67 on the threaded plate 69 is tightened. The screw 67 applies pressure to the rack plate 66 through the threaded plate 69, fixing the relative position of the U-shaped block 65 and the rotating block 63, thus completing the adjustment of the default tilt angle of the pedal 3. The threaded block 612 is threadedly engaged with the bolt 613. Tightening the bolt 613 can change the height of its top. Tightening the bolt 613 downwards lowers its top height. The bottom end of the tension spring 611 is engaged between the top of the bolt 613 and the fixing bracket 610. At this time, the tension spring 611 is in a state of tensile deformation under its own elasticity and the action of the fixing bracket 610 and the bolt 613. The tensile deformation of the tension spring 611 will generate a restoring force. This force acts on the rotating block 63 through the fixing bracket 610, providing a default downward force for the rotating block 63. When the trainee steps on the pedal 3, the pedal 3 is subjected to a downward force and swings. The swing of the pedal 3 drives the U-shaped block 65 to move through the chain 64. The movement of the U-shaped block 65 is transmitted through the rack plate 66 that meshes with it on the rotating block 63, converting the movement of the U-shaped block 65 into the circular motion of the rotating block 63. Since the rotating block 63 is connected by the chain 64, the U-shaped block 65 moves through the chain 64. The bearing 62 is rotatably mounted outside the horizontal shaft 61. The bearing 62 can reduce the friction when the rotating block 63 rotates, so that the rotating block 63 can rotate more smoothly outside the horizontal shaft 61. When the rotating block 63 rotates, it drives the fixed frame 610 to rotate synchronously. The rotation of the fixed frame 610 will cause the tension spring 611 to be further stretched and deformed. According to Hooke's Law, the greater the stretching deformation of the tension spring 611, the greater the elastic force generated. This elastic force is manifested as the resistance encountered by the trainee when stepping on the pedal 3. The further the bolt 613 moves downward, the longer the default stretching length of the tension spring 611. When stepping on the pedal 3 later, the space for the tension spring 611 to stretch further is relatively small, the elastic force to be overcome is greater, and the resistance encountered by the trainee is greater, thereby realizing the adjustment of different pedaling sensations.

[0038] In one embodiment of this utility model, an auxiliary component 7 is further provided on the base plate 1. The auxiliary component 7 includes a base block 71. The base block 71 is fixedly installed on the top of the base plate 1. A slide rod 72 is slidably installed inside the base block 71. A disc 73 is fixedly installed at one end of the slide rod 72. A retaining spring 74 is sleeved on the outside of the slide rod 72. One end of the retaining spring 74 is fixedly installed on the outer wall of the disc 73. The other end of the retaining spring 74 is fixedly installed on the outer wall of an annular gasket sleeved on the outside of the slide rod 72. A rotating rod 75 is fixedly installed at the other end of the slide rod 72. A stop rod 76 is fixedly installed at the other end of the rotating rod 75. In addition, a limiting rod 77 is fixedly installed on the side of the rotating rod 75 near the stop rod 76. A limiting groove 78 is opened on the base block 71. The circumferential movement trajectory of the limiting rod 77 intersects with the limiting groove 78. The outer diameter of the limiting rod 77 is the same as the inner diameter of the limiting groove 78. The fitting allows the limiting rod 77 to smoothly enter the limiting groove 78. In addition, there are two sets of the base block 71, slide rod 72, disc 73, clamping spring 74, rotating rod 75, stop rod 76 and limiting rod 77 on the single base plate 1. The two sets of base blocks 71, slide rod 72, disc 73, clamping spring 74, rotating rod 75, stop rod 76 and limiting rod 77 are mirror images of the vertical center line of the pedal 3 and are set at both ends of the pedal 3. There are multiple sets of limiting grooves 78 on the single base block 71. The multiple sets of limiting grooves 78 are arranged in an evenly spaced circumferential array with the center of the circular cross section of the slide rod 72 as the array center, which better determines the maximum stepping range of the pedal 3. In addition, a support block 4 is fixedly installed on the top of the end of the base plate 1 away from the column 2. The top of the support block 4 is provided with an anti-slip protrusion 5 to prevent the feet of the trainees from slipping when stepping on the pedal 3.

[0039] In this embodiment, when the rotating rod 75 is pulled, the rotating rod 75 is fixedly connected to the sliding rod 72. Therefore, pulling the rotating rod 75 will cause the sliding rod 72 to slide outward inside the base block 71. The disc 73 fixedly installed at one end of the sliding rod 72 will move synchronously and in the same direction as the sliding rod 72. When the disc 73 moves, it will compress the retaining spring 74 sleeved on the outside of the sliding rod 72, causing the retaining spring 74 to deform. At the same time, the limiting rod 77 fixedly installed on the side of the rotating rod 75 near the stop rod 76 will move away from the current limiting groove 78 as the rotating rod 75 moves, releasing the limitation on the rotating rod 75. At this time, the rotating rod 75 can rotate freely. After the limiting rod 77 leaves the limiting groove 78, the rotating rod 75 is rotated towards the bottom end of the base block 71. Since the stop rod 76 is fixedly installed on the rotating rod 75, the stop rod 76 will rotate synchronously, thereby reducing the height of the stop rod 76. When the rotating rod 75 rotates to the target position, that is, the stop rod 76... When the desired height is reached, stop rotating and release the rotating rod 75. At this time, the clamping spring 74, which is in a compressed state, will recover its deformation. The elastic force generated by the recovery of the clamping spring 74 pushes the disc 73 and the slide rod 72 to move back to the initial position, causing the rotating rod 75 to move. Under the action of the recovery of the clamping spring 74, the limiting rod 77 enters the target limiting groove 78. The limiting rod 77 is adapted to the inner diameter of the limiting groove 78. After the limiting rod 77 enters the limiting groove 78, it can fix the position of the rotating rod 75, thereby fixing the current position of the stop rod 76. After the position of the stop rod 76 is fixed, the lower surface of the pedal 3 will contact the stop rod 76 later, increasing the maximum stepping amplitude of the pedal 3. Conversely, rotating the rotating rod 75 in the opposite direction can increase the height of the stop rod 76, causing the lower surface of the pedal 3 to contact the stop rod 76 earlier, reducing the maximum stepping amplitude of the pedal 3, in order to adapt to different application scenarios.

The specific connection methods of each part are all conventional methods such as riveting and welding that are mature in the prior art. The machinery, parts and equipment are all conventional models in the prior art, and will not be described in detail here.

[0041] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
