Abstract
Description
Technical Field
[0001] This utility model relates to the field of aircraft technology, and in particular to an aircraft side stick device and an aircraft. Background Technology
[0002] In traditional aircraft design paradigms, the sidestick layout is usually fixed. However, this design results in the sidestick being either too far or too close to the pilot, whether the pilot is shorter (e.g., between 155cm and 160cm) or taller (e.g., over 185cm), leading to a lack of comfort when operating the sidestick and potentially causing hand fatigue during long flights. Utility Model Content
[0003] Therefore, it is necessary to provide an aircraft side stick device designed to provide a comfortable operating experience for pilots of different heights and effectively alleviate hand fatigue during flight for pilots who are shorter or taller.

[0006] A sliding structure includes a first sliding member and a second sliding member that slide together. The first sliding member is disposed on the side rod body, and the second sliding member is disposed on the aircraft's instrument panel. During the relative sliding of the first and second sliding members, the side rod body can move in a first direction to move closer to or further away from the pilot.
[0007] A locking structure is used to unlock or lock the first slider and the second slider.
[0008] In one embodiment, one of the first slider and the second slider has a slider, and the other has a groove that slides with the slider, the groove and the slider both extending along the first direction.
[0009] In one embodiment, the first slider has the slider, and the second slider has the groove. The shape of the slider matches the shape of the groove. The groove extends through the end of the second slider in the first direction and defines an entrance and exit for the slider to enter and exit the groove. In the arrangement direction of the first and second sliders, the groove includes a communicating opening segment and a main body segment. The opening segment is located outside the groove. At the junction of the opening segment and the main body segment, the width of the opening segment is smaller than the width of the main body segment.
[0010] In one embodiment, the second slider has a plurality of locking points spaced apart in the first direction;
[0011] The locking structure is provided on the side rod body. The locking structure has a lock head that can switch between a locked state and an unlocked state. In the locked state, the lock head locks with a locking point to lock the first sliding member and the second sliding member. In the unlocked state, the lock head separates from the locking point to unlock the first sliding member and the second sliding member.
[0012] In one embodiment, the locking point is a card slot;
[0013] The multiple card slots are arranged at equal intervals, with the distance between two adjacent card slots being 5mm-15mm; and / or
[0014] The depth of the card slot is 3mm-6mm; and / or
[0015] The opening width of the card slot is 5mm-10mm; and / or

[0017] In one embodiment, the locking structure includes an operating member and an elastic member. The middle part of the operating member is rotatably mounted on the side rod body. One end of the operating member has a switching handle, and the other end has the lock head. The elastic member is sandwiched between the side rod body and the operating member, and is located between the lock head and the pivot of the operating member. In the unlocked state, the lock head compresses the elastic member, and in the locked state, the elastic member is at its natural length.
[0018] In one embodiment, the locking structure further includes a fixed base and a pin. The fixed base is disposed on the side rod body. Two symmetrical support ribs are provided on both sides of the fixed base. A first pin hole is provided on each of the two support ribs. A second pin hole is provided on the operating member. The pin passes through the second pin hole and the first pin hole, and the middle part of the operating member is rotatably disposed on the side rod body.
[0019] The fixed base has a first mounting position, the operating member has a second mounting position, one end of the elastic member is mounted at the first mounting position, and the other end is mounted at the second mounting position.
[0020] In one embodiment, the first slider and the second slider are arranged vertically, the side rod body has a first horizontal mounting surface and a second horizontal mounting surface, the first horizontal mounting surface is positioned higher than the second horizontal mounting surface, the first slider is disposed on the first horizontal mounting surface, the second slider is located on the side of the first slider away from the first horizontal mounting surface, the locking structure is disposed on the second horizontal mounting surface, and the lock head can move vertically to switch between the locked state and the unlocked state.
[0021] In one embodiment, the first slider is located at the end of the side rod body away from the operating handle; and / or
[0022] The first sliding member is detachably connected to the side rod body by bolts; and / or
[0023] The second sliding member is detachably connected to the instrument panel by bolts; and / or

[0025] This utility model also provides an aircraft, comprising:
[0026] Instrument panel; and
[0027] The second sliding member of the aforementioned aircraft side stick device is located on the instrument panel.
[0028] In the aforementioned aircraft sidestick device, the sidestick body is mounted on the instrument panel via a sliding structure and a locking structure. When the sidestick body needs to be moved, the locking structure unlocks the first and second sliding members, allowing them to slide relative to each other. During this relative sliding, the sidestick body can move in a first direction, moving closer to or further away from the pilot. This allows the pilot to adjust the sidestick body according to their height, ensuring a comfortable operating experience. Once the sidestick body is adjusted, the locking structure locks the first and second sliding members, securing the sidestick body firmly to the instrument panel. Therefore, this aircraft sidestick device not only securely mounts to the instrument panel but also provides a comfortable operating experience for pilots of different heights, effectively alleviating hand fatigue for shorter or taller pilots during flight. Furthermore, the sliding mechanism between the first and second sliding members allows for movement of the sidestick body, resulting in a simple structure, light weight, and easy maintenance.

[0048] like Figures 1-6 As shown, an aircraft according to an embodiment of the present invention is illustrated. The aircraft includes an instrument panel 10a and an aircraft side stick device 10b. The aircraft side stick device 10b includes a side stick body 200, a sliding structure 300, and a locking structure 400.
[0049] The side stick body 200 has an operating handle 210. The sliding structure 300 includes a first sliding member 310 and a second sliding member 320 that are slidably engaged. The first sliding member 310 is disposed on the side stick body 200. The second sliding member 320 is disposed on the flight instrument panel 10a. During the relative sliding of the first sliding member 310 and the second sliding member 320, the side stick body 200 can move in a first direction to approach or move away from the pilot to the side. The locking structure 400 is used to unlock or lock the first sliding member 310 and the second sliding member 320. When the locking structure 400 locks the first slider 310 and the second slider 320, the first slider 310 and the second slider 320 cannot slide relative to each other, and the position of the side stick body 200 relative to the pilot (or instrument panel 10a) is fixed; when the locking structure 400 unlocks the first slider 310 and the second slider 320, the first slider 310 and the second slider 320 can slide relative to each other, and the position of the side stick body 200 relative to the pilot (or instrument panel 10a) can be adjusted.
[0050] In the aforementioned aircraft side stick device 10b, the side stick body 200 is mounted on the instrument panel 10a via a sliding structure 300 and a locking structure 400. When the side stick body 200 needs to be moved, the locking structure 400 unlocks the first sliding member 310 and the second sliding member 320, allowing them to slide relative to each other. During this relative sliding, the side stick body 200 can move in a first direction, moving closer to or further away from the pilot. This allows the pilot to adjust the side stick body 200 according to their height, ensuring the position matches their height and providing a comfortable control experience. Once the side stick body 200 is adjusted, the locking structure 400 locks the first sliding member 310 and the second sliding member 320, securing the side stick body 200 firmly to the instrument panel 10a. Therefore, the aforementioned aircraft side stick device 10b can not only be firmly fixed to the instrument panel 10a, but also provide a comfortable operating experience for pilots of different heights, effectively alleviating hand fatigue for pilots of shorter or taller stature during flight. Moreover, the movement of the side stick body 200 is achieved through the sliding engagement of the first sliding member 310 and the second sliding member 320, which makes the aforementioned aircraft side stick device 10b simple in structure, lightweight, and easy to maintain.
[0051] In this embodiment, one of the first slider 310 and the second slider 320 has a slider 312, and the other has a groove 322 that slides with the slider 312. Both the groove 322 and the slider 312 extend along a first direction. Thus, the movement of the side stick body 200 in the first direction can be smooth and precisely positioned, and the aforementioned aircraft side stick device 10b can have the characteristics of simple structure, light weight, and convenient maintenance. It is understood that in other embodiments, pulleys and grooves 322 can be used instead of sliders 312 and grooves 322.
[0052] In this embodiment, the first sliding member 310 has a slider 312, and the second sliding member 320 has a groove 322. This facilitates the stable installation of the side rod body 200 on the instrument panel 10a.
[0053] In this embodiment, the shape of the slider 312 matches the shape of the chute 322. The chute 322 penetrates through the end of the second slider 320 in the first direction and defines an entrance / exit 322a for the slider 312 to enter and exit the chute 322. In the arrangement direction of the first slider 310 and the second slider 320, the chute 322 includes a connected opening section 322b and a main body section 322c, and the opening section 322b is located outside the chute 322. At the junction of the opening section 322b and the main body section 322c, the width of the opening section 322b is smaller than the width of the main body section 322c to prevent the slider 312 from falling off from the opening section 322b (that is, in this embodiment, the chute 322 is an anti-falling chute 322). Thus, the slider 312 can be installed in the chute 322 through the entrance / exit 322a, and the opening section 322b can prevent the slider 312 from falling off from the opening section 322b. Specifically, in this embodiment, the cross-section of the chute 322 can be in the shape of "Ω" or "几".
[0054] In this embodiment, the first slider 310 is provided at one end of the side rod body 200 away from the operation handle 210. Thus, without increasing the size of the side rod body 200, it is possible to prevent the first slider 310 from interfering with the operation handle 210. It can be understood that in other embodiments, the first slider 310 can also be provided between the two ends of the side rod body 200.
[0055] In this embodiment, the first slider 310 is detachably connected to the side rod body 200. Thus, it is convenient to disassemble and replace the first slider 310, improving the maintenance efficiency of the first slider 310. It can be understood that in other embodiments, the first slider 310 can also be bonded or welded to the side rod body 200. In this embodiment, the first slider 310 and the side rod body 200 are detachably connected by a bolt (the first bolt 330). Thus, not only is it convenient to disassemble, but also the first slider 310 and the side rod body 200 can be firmly connected. In this embodiment, the first slider 310 includes a connecting portion 314 and a slider 312 provided on the connecting portion 314. The side rod body 200 has a first screw hole 220, and the connecting portion 314 has a first mounting hole 314a corresponding to the first screw hole 220. The first bolt 330 passes through the first mounting hole 314a and is screwed to the first screw hole 220.
[0056] In this embodiment, the second sliding member 320 is detachably connected to the instrument panel 10a. This facilitates the disassembly and replacement of the second sliding member 320, improving its maintenance efficiency. It is understood that in other embodiments, the second sliding member 320 may also be bonded or welded to the instrument panel 10a. In this embodiment, the second sliding member 320 is detachably connected to the instrument panel 10a by bolts (second bolts 340). This not only facilitates disassembly but also ensures a stable connection between the second sliding member 320 and the instrument panel 10a. In this embodiment, the second sliding member 320 includes a slide rail 324 and connecting members 326. One side of the slide rail 324 has a groove 322. The connecting members 326 are located on the side of the slide rail 324 away from the groove 322. There are two connecting members 326, located at both ends of the slide rail 324 in the first direction. The instrument panel 10a has two sub-platforms 12. Each sub-platform 12 has a second screw hole 12a. The connector 326 has a second mounting hole 326a corresponding to the second screw hole 12a. The second bolt 340 passes through the second mounting hole 326a and is screwed into the second screw hole 12a. In this embodiment, the connector 326 is L-shaped, and a reinforcing rib 328 is provided on the inner side of the connector 326.
[0057] In this embodiment, the second sliding member 320 has a plurality of locking points 329 spaced apart in a first direction. A locking structure 400 is provided on the side stick body 200. The locking structure 400 has a locking head 412. The locking head 412 can switch between a locked state and an unlocked state. In the locked state, the locking head 412 locks with a locking point 329 to lock the first sliding member 310 and the second sliding member 320. In the unlocked state, the locking head 412 separates from the locking point 329 to unlock the first sliding member 310 and the second sliding member 320. Thus, the locking structure 400 can indirectly unlock or lock the first sliding member 310 and the second sliding member 320, facilitating unlocking or locking while also ensuring that the aircraft side stick device 10b is securely fixed to the instrument panel 10a. It is understood that in other embodiments, the locking structure 400 can also be provided on the second sliding member 320, and a plurality of locking points 329 spaced apart in a first direction can be provided on the side stick body 200. It is understood that in other embodiments, the locking structure 400 can also directly unlock or lock the first sliding member 310 and the second sliding member 320. For example, the locking structure 400 may include a screw and a nut. The screw can be simultaneously inserted into the first sliding member 310 and the second sliding member 320. The nut cooperates with the screw to lock the first sliding member 310 and the second sliding member 320. After removing the nut and the screw, the first sliding member 310 and the second sliding member 320 can be unlocked.
[0058] In this embodiment, as Figure 2 and Figure 7As shown, multiple locking points 329 are arranged at equal intervals. Thus, the side stick body 200 moves a distance that is a multiple of the distance between two adjacent locking points 329 each time, making it easier to control the movement distance of the side stick body 200. In this embodiment, the distance between two adjacent locking points 329 is 5mm-15mm. After determining the maximum movement distance of the side stick body 200, a smaller distance between two adjacent locking points 329 results in a larger number of locking points 329, which in turn increases the manufacturing difficulty of the second sliding member 320. Conversely, a larger distance between two adjacent locking points 329 is not conducive to accurately matching pilots of different heights. Considering the above factors, the distance between two adjacent locking points 329 is set to 5mm-15mm. Specifically, in this embodiment, the distance between two adjacent locking points 329 is 10mm.
[0059] In this embodiment, the locking point 329 is a slot. Thus, in the locked state, the lock head 412 can be engaged in the slot. This engaging and fixing method ensures that the second sliding member 320 has good stability and durability when subjected to operating forces. In this embodiment, the depth of the slot is 3mm-6mm. If the depth of the slot is too small, the lock head 412 can easily come out of the slot, affecting the secure connection; if the depth of the slot is too large, it will affect the structural strength of the second sliding member 320. Considering the above factors, the depth of the slot is set to 3mm-6mm. Specifically, in this embodiment, the depth of the slot is set to 4mm. In this embodiment, in the first direction, the opening width of the slot is 5mm-10mm. The smaller the opening width of the slot, the less conducive it is for the lock head 412 to enter the slot; the larger the opening width of the slot, the more it will affect the structural strength of the second sliding member 320. Considering the above factors, the opening width of the slot is set to 5mm-10mm. Specifically, in this embodiment, the opening width of the slot is set to 7mm. In this embodiment, the outer diameter of the lock head 412 gradually decreases and the width of the slot gradually decreases in the direction in which the lock head 412 enters the slot. This not only facilitates the entry of the lock head 412 into the slot, but also ensures a secure engagement between the lock head 412 and the slot.
[0060] In this embodiment, as Figure 2 , Figure 8 and Figure 9As shown, the locking structure 400 includes an operating member 410 and an elastic member 420. The operating member 410 is rotatably mounted on the side rod body 200 at its center. One end of the operating member 410 has a switching handle 414, and the other end has a lock head 412. The elastic member 420 is sandwiched between the side rod body 200 and the operating member 410, and is located between the lock head 412 and the pivot (pin 440) of the operating member 410. In the unlocked state, the lock head 412 compresses the elastic member 420; in the locked state, the elastic member 420 is at its natural length. Thus, by operating the switching handle 414, the locking head 412 is rotated relative to the side stick body 200, causing the locking head 412 to separate from the locking point 329 and compressing the elastic element 420, thereby unlocking. When the side stick body 200 moves to the preset position, releasing the switching handle 414 causes the locking head 412 to rotate relative to the side stick body 200 and engage with the locking point 329 under the restoring force of the elastic element 420 (during the process of the elastic element 420 returning from the compressed state to its natural state), achieving locking. The above-mentioned locking structure 400 is very easy to operate, and since it is a manual mechanical structure, it does not require additional power support. This makes the aircraft side stick device 10b widely applicable in various types of aircraft, including small or economical aircraft. Furthermore, the aircraft side stick device 10b is characterized by its simple structure, light weight, and convenient maintenance. It is understood that in other embodiments, an electric structure can also be used to control the rotation of the lock head 412 relative to the side rod body 200. In this case, the switching handle 414 can be omitted. It is understood that in other embodiments, the locking structure 400 can also be a telescopic rod, with the lock head 412 being one end of the telescopic rod. When unlocking, the lock head 412 retracts and separates from the locking point 329. When locking, the lock head 412 extends and engages with the locking point 329.
[0061] In this embodiment, the locking structure 400 further includes a fixed base 430 and a pin 440. The fixed base 430 is disposed on the side rod body 200. Two symmetrical support ribs 432 are provided on both sides of the fixed base 430. The two support ribs 432 are respectively provided with first pin holes 434. The operating member 410 is provided with a second pin hole 416. The pin 440 passes through the second pin hole 416 and the first pin hole 434, so that the middle part of the operating member 410 is rotatably disposed on the side rod body 200. The fixed base 430 is provided with a first mounting position 430a. The operating member 410 is provided with a second mounting position 410a. One end of the elastic member 420 is installed at the first mounting position 430a, and the other end is installed at the second mounting position 410a. In this way, it is very convenient to install the locking structure 400 on the side rod body 200. Specifically, in this embodiment, the elastic member 420 is a spring.
[0062] In this embodiment, the locking structure 400 is detachably connected to the side rod body 200. This facilitates the disassembly and replacement of the locking structure 400, improving its maintenance efficiency. It is understood that in other embodiments, the locking structure 400 may also be bonded or welded to the side rod body 200. In this embodiment, the locking structure 400 and the side rod body 200 are detachably connected by bolts (third bolt 350). This not only facilitates disassembly but also ensures a secure connection between the locking structure 400 and the side rod body 200. In this embodiment, the side rod body 200 has a third screw hole 230, and the fixing base 430 has a third mounting hole 436 corresponding to the third screw hole 230. The third bolt 350 passes through the third mounting hole 436 and is screwed into the third screw hole 230.
[0063] In this embodiment, as Figure 2 and Figure 3 As shown, the first slider 310 and the second slider 320 are arranged vertically. The lock head 412 can move vertically to switch between a locked state and an unlocked state. This facilitates the stable mounting of the side rod body 200 on the dashboard 10a. It is understood that in other embodiments, the first slider 310 and the second slider 320 can be arranged in the front-back direction or the left-right direction.
[0064] In this embodiment, the side rod body 200 has a first horizontal mounting surface 240 and a second horizontal mounting surface 250. The first horizontal mounting surface 240 is positioned higher than the second horizontal mounting surface 250. A first sliding member 310 is disposed on the first horizontal mounting surface 240. A second sliding member 320 is located on the side of the first sliding member 310 away from the first horizontal mounting surface 240. A locking structure 400 is disposed on the second horizontal mounting surface 250. This facilitates the movement of the locking point 329 in the vertical direction to switch between the locked and unlocked states.
[0065] like Figures 10-12 As shown, when the side rod body 200 needs to be moved, the operator manually pulls down the switching handle 414. At this time, the locking head 412 on the operating member 410 will rotate relative to the side rod body 200 and disengage from its original locking point 329 (slot). The first sliding member 310 and the second sliding member 320 can slide relative to each other, so that the side rod body 200 can move. When the side rod body 200 moves to the preset position, the operator releases the switching handle 414. Under the action of the elastic force of the elastic member 420 (during the process of the elastic member 420 returning from the compressed state to the natural state), the locking head 412 rotates relative to the side rod body 200 and locks onto the locking point 329, locking the first sliding member 310 and the second sliding member 320, so that the side rod body 200 is fixed on the dashboard 10a.
[0066] The technical features of the above embodiments can be combined in any way.
