[0033] Please refer to Figure 1 , the embodiment of the present invention provides an aircraft 10 for performing flight operations. The fairing lock seat assembly 100 therein has a simple structure, can conveniently and quickly adjust the position of the lock seat 150, is convenient for later maintenance or part replacement, and has strong practicability.

[0034] In this embodiment, the aircraft 10 is a helicopter. The aircraft 10 includes a fairing lock seat assembly 100, a fuselage 200, and a locking mechanism 300. The locking mechanism 300 is installed on the fuselage 200 and cooperates with the fairing lock seat assembly 100. The locking mechanism 300 can move relative to the fairing lock seat assembly 100 to open or close the fairing lock seat assembly 100. However, it is not limited thereto. In other embodiments, the aircraft 10 can be a glider or an aircraft, and the type of the aircraft 10 is not specifically limited.

[0035] Please refer to in combination Figure 2 and Figure 3 , the fairing lock seat assembly 100 includes a fairing body 110, a bracket 120, a mounting member 130, a first connecting member 140, a lock seat 150, a second connecting member 160, a limit pad 170, and an adjustment pad 180. The fairing body 110 is fixedly connected to the bracket 120. The bracket 120 is connected to the mounting member 130 through the first connecting member 140, and the relative position between the bracket 120 and the mounting member 130 is adjustable. The mounting member 130 is connected to the lock seat 150 through the second connecting member 160, and the relative position between the mounting member 130 and the lock seat 150 is adjustable. The limit pad 170 is clamped between the mounting member 130 and the lock seat 150 and cooperates with the lock seat 150. The limit pad 170 is used to limit the lock seat 150. The adjustment pad 180 is clamped between the mounting member 130 and the lock seat 150, and the distance between the mounting member 130 and the lock seat 150 is adjusted by increasing or decreasing the number of adjustment pads 180.

[0036] In this embodiment, the lock base 150 is provided with a locking hole 151, and the locking mechanism 300 includes a locking post 310. The locking post 310 can extend into the locking hole 151 to lock the relative position of the locking mechanism 300 and the lock base 150, thereby closing the fairing body 110. The locking post 310 can also retract from the locking hole 151 to release the locking state of the locking mechanism 300 and the lock base 150, thereby opening the fairing body 110.

[0037] Please refer to Figure 4 , it should be noted that the bracket 120 is provided with a first connection structure 121, and the mounting member 130 is provided with a second connection structure 131. The first connection structure 121 is connected to the second connection structure 131 through a first connecting member 140. The first connection structure 121 can move relative to the second connection structure 131 in the first direction to adjust the relative position of the mounting member 130 and the bracket 120 in the first direction, thereby adjusting the relative position of the lock base 150 and the fairing body 110 in the first direction.

[0038] The mounting member 130 is provided with a third connection structure 132, and the lock base 150 is provided with a fourth connection structure 152. The third connection structure 132 is connected to the fourth connection structure 152 through a second connecting member 160. The third connection structure 132 can move relative to the fourth connection structure 152 in the second direction to adjust the relative position of the lock base 150 and the mounting member 130 in the second direction, thereby adjusting the relative position of the lock base 150 and the fairing body 110 in the second direction.

[0039] Furthermore, an adjusting pad 180 is disposed between the mounting member 130 and the limiting pad 170. The number of the adjusting pads 180 is at least one. By increasing or decreasing the number of the adjusting pads 180, the thickness of the entire adjusting pad 180 is changed, so as to adjust the distance between the mounting member 130 and the lock base 150. In this way, the adjusting pad 180 can adjust the relative position of the lock base 150 and the mounting member 130 in the third direction, thereby adjusting the relative position of the lock base 150 and the fairing body 110 in the third direction.

[0040] Please refer to Figure 5 , it should be noted that the second direction is perpendicular to the first direction, the third direction is perpendicular to the first direction, and the second direction is perpendicular to the third direction, so as to facilitate the adjustment of the position of the lock base 150 in three mutually perpendicular dimensions, with high position adjustment efficiency and good position adjustment effect. For the sake of easy understanding, a spatial rectangular coordinate system is established, wherein the first direction is the direction where the X axis is located, the second direction is the direction where the Y axis is located, and the third direction is the direction where the Z axis is located.

[0041] In this embodiment, the first connection structure 121 is the first through hole 122, the second connection structure 131 is the first waist-shaped hole 133, and the first direction is the long axis direction of the first waist-shaped hole 133. Specifically, the first connecting member 140 is a bolt (not shown in the figure) and a nut (not shown in the figure). The bolt and the nut cooperate, and the bolt can sequentially pass through the first waist-shaped hole 133 and the first through hole 122 and be tightened relative to the nut to fix the relative positions of the bracket 120 and the mounting member 130. When it is necessary to adjust the relative position of the mounting member 130 and the bracket 120 in the first direction, first loosen the bolt relative to the nut, and then move the mounting member 130 in the first direction. At this time, the first waist-shaped hole 133 moves relative to the first through hole 122 in the first direction. After the mounting member 130 moves to the first preset position, tighten the bolt relative to the nut to complete the position adjustment action.

[0042] It should be noted that the bracket 120 is provided with a first rack portion 123, and the mounting member 130 is provided with a second rack portion 134. The first rack portion 123 and the second rack portion 134 are engaged to further fix the relative positions of the mounting member 130 and the bracket 120 and prevent the mounting member 130 from displacing relative to the bracket 120. Specifically, the tooth grooves of the first rack portion 123 and the tooth grooves of the second rack portion 134 both extend perpendicular to the long axis direction of the first waist-shaped hole 133. The engagement of the first rack portion 123 and the second rack portion 134 can prevent the mounting member 130 from displacing relative to the bracket 120 in the first direction. In addition, during the process of adjusting the relative position of the mounting member 130 and the bracket 120 in the first direction, the moving distance of the mounting member 130 is an integer multiple of the tooth groove width of the first rack portion 123 or the second rack portion 134 to ensure that the first rack portion 123 can still be engaged with the second rack portion 134 after the position of the mounting member 130 is adjusted.

[0043] In this embodiment, the third connection structure 132 is the second through hole 135, the fourth connection structure 152 is the second waist-shaped hole 153, and the second direction is the long axis direction of the second waist-shaped hole 153. Specifically, the second connecting member 160 is a bolt (not shown in the figure) and a nut (not shown in the figure). The bolt and the nut cooperate, and the bolt can sequentially pass through the second waist-shaped hole 153 and the second through hole 135 and be tightened relative to the nut to fix the relative positions of the lock seat 150 and the mounting member 130. When it is necessary to adjust the relative position of the lock seat 150 and the mounting member 130 in the second direction, first loosen the bolt relative to the nut, and then move the lock seat 150 in the second direction. At this time, the second waist-shaped hole 153 moves relative to the second through hole 135 in the second direction. After the lock seat 150 moves to the second preset position, tighten the bolt relative to the nut to complete the position adjustment action.

[0044] It should be noted that the limit pad 170 is provided with a third rack portion 171, and the lock seat 150 is provided with a fourth rack portion 154. The third rack portion 171 meshes with the fourth rack portion 154 to fix the relative positions of the limit pad 170 and the lock seat 150 and prevent the lock seat 150 from displacing relative to the mounting member 130. Specifically, the tooth grooves of the third rack portion 171 and the fourth rack portion 154 both extend perpendicular to the long axis direction of the second waist-shaped hole 153. The meshing of the third rack portion 171 and the fourth rack portion 154 can prevent the lock seat 150 from displacing relative to the mounting member 130 in the second direction. In addition, during the process of adjusting the relative position of the lock seat 150 and the mounting member 130 in the second direction, the moving distance of the lock seat 150 is an integer multiple of the tooth groove width of the third rack portion 171 or the fourth rack portion 154, so as to ensure that the third rack portion 171 can still mesh with the fourth rack portion 154 after the position of the lock seat 150 is adjusted.

[0045] It is worth noting that the tooth groove width of the first rack portion 123 ranges from 0.5 mm to 2 mm, the tooth groove width of the second rack portion 134 ranges from 0.5 mm to 2 mm, the tooth groove width of the third rack portion 171 ranges from 0.5 mm to 2 mm, and the tooth groove width of the fourth rack portion 154 ranges from 0.5 mm to 2 mm. A reasonable tooth groove width can improve the adjustment accuracy of the position of the mounting member 130 on the premise of ensuring the limiting effect. In this embodiment, the tooth groove widths of the first rack portion 123, the second rack portion 134, the third rack portion 171, and the fourth rack portion 154 are all 1 mm, but it is not limited thereto. In other embodiments, the tooth groove widths of the first rack portion 123, the second rack portion 134, the third rack portion 171, and the fourth rack portion 154 can all be 0.5 mm, or can all be 2 mm. The sizes of the tooth groove widths of the first rack portion 123, the second rack portion 134, the third rack portion 171, and the fourth rack portion 154 are not specifically limited.

[0046] In this embodiment, the limit pad 170 is provided with a through hole 172, and the adjusting pad 180 is provided with a slot 181. The second connecting member 160 sequentially passes through the second waist-shaped hole 153 of the lock seat 150, the through hole 172 of the limit pad 170, the slot 181 of the adjusting pad 180, and the second through hole 135 of the mounting member 130 to fix the relative positions of the lock seat 150, the limit pad 170, the adjusting pad 180, and the mounting member 130.

[0047] The bracket 120 includes a first mounting portion 124, a connecting portion 125, and a second mounting portion 126. The first mounting portion 124 is fixedly connected to the second mounting portion 126 through the connecting portion 125. In this embodiment, the first mounting portion 124, the connecting portion 125, and the second mounting portion 126 are integrally formed to improve the connection strength. The connecting portion 125 is U-shaped, and the first mounting portion 124 and the second mounting portion 126 are respectively disposed on both sides of the connecting portion 125. The connecting portion 125 is fixedly connected to the fairing body 110.

[0048] In this embodiment, the number of the first through holes 122, the first waist-shaped holes 133, and the first connectors 140 is two. One first through hole 122 is disposed on the first mounting portion 124, and the other first through hole 122 is disposed on the second mounting portion 126. The two first waist-shaped holes 133 are oppositely disposed at both ends of the mounting member 130. Each first connector 140 passes through one first waist-shaped hole 133 and one first through hole 122 to improve the connection stability between the mounting member 130 and the bracket 120. Further, the number of the second through holes 135, the second waist-shaped holes 153, and the second connectors 160 is two. The two second through holes 135 are spaced apart and are both disposed between the two first waist-shaped holes 133. Each second connector 160 passes through one second waist-shaped hole 153 and one second through hole 135 to improve the connection stability between the lock base 150 and the mounting member 130.

[0049] In the fairing lock base assembly 100 provided by the embodiment of the present invention, the fairing body 110 is fixedly connected to the bracket 120, the lock base 150 is connected to the mounting member 130.
