[0036] Figure 1 FIG. 1 shows a schematic structural diagram of an auxiliary assembly device of a passenger service unit provided in this embodiment. Figure 2 The schematic diagram shows the structure of the auxiliary assembly device of the passenger service unit provided in this embodiment being assembled on the first guide rail 100 and the second guide rail 200. Figure 3 FIG. 2 shows a schematic structural diagram of the first assembly component 2 provided in this embodiment. Figure 4 FIG. 2 shows a schematic diagram of the structure of the second assembly component 3 provided in this embodiment. Figure 1-Figure 4 As shown, the auxiliary assembly device of the passenger service unit is used to assist in adjusting the passenger service unit. The passenger service unit includes a first guide rail 100 and a second guide rail 200. The auxiliary assembly device of the passenger service unit includes a connecting plate 1, a first assembly component 2 and a second assembly component 3. The first assembly component 2 is arranged on one side of the connecting plate 1. The first assembly component 2 includes a first connecting component 21, and the first connecting component 21 can be connected to the first guide rail 100; the second assembly component 3 is arranged on the other side of the connecting plate 1, and the second assembly component 3 includes a second connecting component 31, and the second connecting component 31 can be connected to the second guide rail 200. When the second guide rail 200 does not meet the installation accuracy, the second connecting component 31 cannot be connected to the second guide rail 200.

[0037] The first assembly component 2 connects the connecting plate 1 to the first guide rail 100 through the setting of the first connecting component 21, and the second assembly component 3 connects the connecting plate 1 to the second guide rail 200 through the setting of the second connecting component 31. The connection relationship between the second connecting component 31 and the second guide rail 200 reflects the installation accuracy of the second guide rail 200. When the installation accuracy of the second guide rail 200 meets the requirements, the second connecting component 31 is connected to the second guide rail 200. When the second guide rail 200 does not meet the requirements of the installation accuracy, the second connecting component 31 cannot be connected to the second guide rail 200, so that the operator can readjust the second guide rail 200 through the feedback of the second connecting component 31, thereby reducing the time for the operator to repeatedly adjust, which can not only ensure the installation accuracy of the first guide rail 100 and the second guide rail 200, but also improve the assembly efficiency of the first guide rail 100 and the second guide rail 200.

[0038] like Figure 3 Combined with Figure 1 , Figure 2 and Figure 4 As shown, the first connecting component 21 includes a first clamping block 211 and a slider 212. The first clamping block 211 is provided with a first clamping groove 2111, and the slider 212 is provided with a clamping portion 2121. The first clamping groove 2111 can cooperate with the clamping portion 2121 to enable the first connecting component to be clamped on the first guide rail 100. The first connecting component 21 cooperates with the clamping portion 2121 through the first clamping groove 2111 and is clamped with the first guide rail 100, thereby realizing the connection between the first connecting component 21 and the first guide rail 100.

[0039] Furthermore, the slider 212 can slide relative to the first clamping block 211 to disconnect the first connecting component 21 from the first guide rail 100. The relative sliding setting drives the clamping portion 2121 to cooperate or separate with the first clamping groove 2111, thereby realizing the connection or disconnection between the first connecting component 21 and the first guide rail 100, and realizing quick disassembly and assembly, so as to improve the disassembly and assembly efficiency of the auxiliary assembly device of the passenger service unit.

[0040] Furthermore, the first assembly component 2 also includes a first base 22, which is connected to the connecting plate 1. A limiting portion 221 is also provided on the first base 22, and an abutting portion 2112 is provided on the first clamping block 211. The limiting portion 221 can abut against the abutting portion 2112. By setting the limiting portion 221 and the abutting portion 2112, the connecting plate 1 is prevented from exceeding the limit when flipping, thereby preventing the second connecting component 31 from still being able to connect to the second guide rail 200 when the second guide rail 200 does not meet the installation accuracy.

[0041] Furthermore, the first assembly component 2 also includes a first pin shaft 23, which is arranged on the first base 22. A first pin hole is arranged on the first clamping block 211. The first pin shaft 23 is inserted into the first pin hole so that the first clamping block 211 can rotate around the axis of the first pin shaft 23. By setting the first pin shaft 23 and the first pin hole, the first base 22 can be flipped after the first connecting component 21 is clamped with the first guide rail 100, thereby driving the connecting plate 1 to flip.

[0042] Preferably, the first assembly component 2 also includes a first positioning member 24, a first positioning hole is provided on the first base 22, and a second positioning hole is provided on the connecting plate 1, and the first positioning member 24 is sequentially passed through the first positioning hole and the second positioning hole to fix the relative position of the first base 22 and the connecting plate 1, thereby preventing misalignment between the first base 22 and the connecting plate 1 to ensure the assembly accuracy of the first assembly component 2.

[0043] Furthermore, a limiting groove 2113 is provided on the first clamping block 211, and the slider 212 is provided in the limiting groove 2113 and can slide relative to the limiting groove 2113. By providing the limiting groove 2113, the slider 212 can be accommodated and the slider 212 can be limited when sliding relative to the first clamping block 211, thereby preventing the first connecting component 21 from failing due to sliding deviation.

[0044] Furthermore, the first assembly component 2 also includes a first elastic member 25, and a slide rod 2122 is provided on the slider 212. The first elastic member 25 is sleeved on the rod wall of the slide rod 2122. One end of the first elastic member 25 is fixedly connected to the first clamping block 211, and the other end of the first elastic member 25 is fixedly connected to an end of the slide rod 2122 away from the first clamping block 211. The slide rod 2122 is provided to facilitate the operator to push the slider 212 through the slide rod 2122, so that the first clamping groove 2111 is separated from the clamping portion 2121, and they no longer cooperate with the first guide rail 100 to be clamped. The first elastic member 25 is provided so that after the operator releases the slide rod 2122, the first elastic member 25 drives the slider 212 to reset.

[0045] In this embodiment, the first elastic member 25 is a spring. In other embodiments, the first elastic member 25 can also be other elastic members with a reset effect, which is not specifically limited in this embodiment.

[0046] like Figure 4 Combined with Figure 1-Figure 3 As shown, the second connecting component 31 includes a second clamping block 311 and a second base 312, the second clamping block 311 is provided with a second clamping groove 3111, and the second base 312 is provided with a third clamping groove 3121, the second clamping groove 3111 can cooperate with the third clamping groove 3121 to enable the second connecting component 31 to be clamped on the second guide rail 200, the second connecting component 31 cooperates with the third clamping groove 3121 through the second clamping groove 3111 and can be clamped with the second connecting component 31, thereby realizing that the first connecting component 21 can be connected to the second guide rail 200.

[0047] Furthermore, the second clamping block 311 can rotate relative to the second base 312 to disconnect the second connecting component 31 from the second guide rail 200. The second clamping groove 3111 and the third clamping groove 3121 are driven to cooperate or separate through the relative rotation setting, so that the second connecting component 31 and the second guide rail 200 can be connected or disconnected, and can be quickly disassembled and assembled to improve the disassembly and assembly efficiency of the auxiliary assembly device of the passenger service unit. The relative rotation setting can also make it impossible to connect the second connecting component 31 to the second guide rail 200 when the second guide rail 200 does not meet the installation accuracy.

[0048] Preferably, the second assembly component 3 also includes a second pin shaft 32, and a second pin hole is provided on the second clamping block 311. The second pin shaft 32 is passed through the second pin hole so that the second clamping block 311 can rotate around the axis of the second pin shaft 32. Through the setting of the second pin shaft 32 and the second pin hole, the second clamping block 311 can rotate relative to the second base 312.

[0049] Preferably, the second assembly component 3 also includes a second positioning piece, a third positioning hole is provided on the second base 312, and a fourth positioning hole is provided on the connecting plate 1. The second positioning piece is sequentially passed through the third positioning hole and the fourth positioning hole to fix the relative position of the second base 312 and the connecting plate 1, thereby preventing misalignment between the second base 312 and the connecting plate 1 and ensuring the assembly accuracy of the second assembly component 3.

[0050] Furthermore, the second assembly component 3 also includes a second elastic member 33, which is sleeved on the outer wall of the second pin shaft 32, one end of the second elastic member 33 abuts against the second clamping block 311, and the other end abuts against the second base 312, and the second elastic member 33 is set to drive the second clamping block 311 to reset.

[0051] In this embodiment, the second elastic member 33 is a torsion spring. In other embodiments, the second elastic member 33 can also be other elastic members with a reset effect, which is not specifically limited in this embodiment.

[0052] Preferably, the portion of the first connecting component 21 in contact with the first guide rail 100 and the portion of the second connecting component 31 in contact with the second guide rail 200 are both provided with a buffer portion to avoid damage to the portion of the first connecting component 21 in contact with the first guide rail 100 and the portion of the second connecting component 31 in contact with the second guide rail 200.

[0053] In this embodiment, the buffer portion is made of soft plastic material. In other embodiments, the buffer portion can also be made of other materials with buffering effect, which is not specifically limited in this embodiment.

[0054] In this embodiment, the connecting plate 1 is made of aluminum alloy to ensure the overall rigidity of the auxiliary assembly device of the passenger service unit and reduce the weight of the connecting plate 1. In other embodiments, the connecting plate 1 can also be made of other hard metal materials, which is not specifically limited in this embodiment.

[0055] Preferably, a weight-reducing groove 11 is provided on the connecting plate 1 to prevent the auxiliary assembly device of the passenger service unit from being too heavy, thereby causing deformation of the aircraft during use.
