[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] Those skilled in the art will understand that although some embodiments herein include certain features included in other embodiments but not others, combinations of features from different embodiments are intended to be within the scope of this invention and form different embodiments. For example, in the claims, any of the claimed embodiments can be used in any combination.

[0022] The following is a reference to the appendix. Figure 1 To be continued Figure 2 This invention describes a suspended object simulator.

[0023] Current suspended object simulators, due to their hand-welded thin-plate fairings, not only have poor structural strength but also fail to meet the requirements for lightweight applications.

[0024] Therefore, this utility model provides a suspended object simulator, such as... Figure 1As shown, the device includes an outer shell 1. The top of the outer shell 1 has a front connector 2 and a rear connector 3. The outer shell 1 is connected to the aircraft via the front connector 2 and the rear connector 3. The outer shell 1 has a first storage compartment and a second storage compartment sequentially provided for accommodating internal equipment. The top of the first storage compartment has a first cover plate 4 that matches the first storage compartment, and the top of the second storage compartment has a second cover plate 5 that matches the second storage compartment. Specifically, after the internal equipment is placed in the first and second storage compartments of the outer shell 1, it is sealed using the first cover plate 4 and the second cover plate 5. Then, the outer shell 1 is connected to the aircraft via the front connector 2 and the rear connector 3. That is, the outer shell 1, together with the first cover plate 4 and the second cover plate 5, forms a hollow frame structure, which not only ensures structural strength but also meets the requirements for lightweight use.

[0025] Preferably, the outer shell 1 includes a left side plate 101 and a right side plate 102, which are spliced ​​together to form the outer shell 1. The left side plate 101 and the right side plate 102 are fixed together by screws. Specifically, the structure of the outer shell 1 formed by splicing the left side plate 101 and the right side plate 102 reduces the weight to a certain extent compared with the integral outer shell 1. The screw connection can generate a preload between the left side plate 101 and the right side plate 102, so that the left side plate 101 and the right side plate 102 fit tightly together, which can effectively transfer the load and make the overall structure uniformly stressed.

[0026] As a preferred option, such as Figure 2 As shown, a first connector groove 1011 and a second connector groove 1012 are sequentially formed on the left side plate 101, and a third connector groove 1021 and a fourth connector groove 1022 are sequentially formed on the right side plate 102. When the left side plate 101 and the right side plate 102 are spliced ​​together, the first connector groove 1011 and the third connector groove 1021 fit together to form a front connector guide groove 100 that matches the front connector 2. The front connector 2 is fixed on the front connector guide groove 100. The second connector groove 1012 and the fourth connector groove 1022 fit together to form a rear connector guide groove 200 that matches the rear connector 3. The rear connector 3 is fixed on the rear connector guide groove 200. Specifically, through the left side plate 101 and the right side plate 102... The side panel 102 is slotted and spliced ​​to form the front connector guide groove 100 and the rear connector guide groove 200. While ensuring the connection function between the outer shell 1 and the front connector 2 and the rear connector 3, it does not introduce large and heavy connecting components, which helps to maintain the overall lightweight design of the outer shell 1. At the same time, the front and rear connectors are fixed on the front and rear connector guide grooves, making the connection between the connectors and the outer shell 1 more stable. Compared with the simple surface connection method, the design of the front and rear connector guide grooves provides the front and rear connectors with more accurate positioning and a more solid fixing method, which can prevent the front and rear connectors from loosening or shifting during operation, thereby ensuring the stability of the overall structure of the outer shell 1.

[0027] Preferably, the front connector guide groove 100 has a first screw hole 1001, and the front connector 2 has a first through hole 201. A bolt passes through the first through hole 201 and is screwed into the first screw hole 1001, so that the front connector 2 is fixed on the front connector guide groove 100. The rear connector guide groove 200 has a second screw hole 2001, and the rear connector 3 has a second through hole 301. A bolt passes through the second through hole 301 and is screwed into the second screw hole 2001, so that the rear connector 3 is fixed on the rear connector guide groove 200. Specifically, the front connector 2 and the front connector guide groove 100 and the rear connector 3 and the rear connector guide groove 200 are fixed by a threaded connection, which facilitates later maintenance and replacement.

[0028] Preferably, a first guide plate 1013, a second guide plate 1014 and a third guide plate 1015 are sequentially arranged on the left side plate 101, and a fourth guide plate 1023, a fifth guide plate 1024 and a sixth guide plate 1025 are sequentially arranged on the right side plate 102.

[0029] When the left side panel 101 and the right side panel 102 are spliced ​​together, the first guide plate 1013 and the fourth guide plate 1023 are attached to form the first limiting plate 300, the second guide plate 1014 and the fifth guide plate 1024 are attached to form the second limiting plate 400, and the third guide plate 1015 and the sixth guide plate 1025 are attached to form the third limiting plate 500. The first accommodating compartment is located between the first limiting plate 300 and the second limiting plate 400. The first limiting plate 300 and the second limiting plate 400 together form the first guide groove that matches the first cover plate 4. The second accommodating compartment is located between the second limiting plate 400 and the third limiting plate 500. The second limiting plate 400 and the third limiting plate 500 together form the second guide groove that matches the second cover plate 5. Specifically, taking the first guide plate 1013 and the fourth guide plate 1023 as abutting to form the first limiting plate 300, and the second guide plate 1014 and the fifth guide plate 1024 as abutting to form the second limiting plate 400 as an example, this structure can effectively resist the impact of external forces on the first cover plate 4. If the outer shell 1 is subjected to external collisions or vibrations, the first limiting plate 300 and the second limiting plate 400 can prevent the deformation of the first cover plate 4 because it restricts the displacement of the first cover plate 4 between the first limiting plate 300 and the second limiting plate 400, making the overall structure more stable.

[0030] Preferably, the first cover plate 4 is fixed to the first guide groove with screws, and the second cover plate 5 is fixed to the second guide groove with screws, which facilitates later maintenance and replacement.

[0031] Preferably, the internal equipment is installed on the first cover plate 4 and the second cover plate 5 respectively. The first cover plate 4 is fixedly connected to the first accommodating compartment, and the internal equipment installed on the first cover plate 4 is located inside the first accommodating compartment. The second cover plate 5 is fixedly connected to the second accommodating compartment, and the internal equipment installed on the second cover plate 5 is located inside the second accommodating compartment, thereby facilitating personnel to perform maintenance and installation / removal.

[0032] Preferably, both the first cover plate 4 and the second cover plate 5 are provided with reinforcing ribs to improve the structural strength of the first cover plate 4 and the second cover plate 5; preferably, both the left side plate 101 and the right side plate 102 are provided with reinforcing ribs.

[0033] In one specific embodiment, the left side plate 101, the right side plate 102, the first cover plate 4, and the second cover plate 5 are all made of aluminum alloy thick plate 2A12T351, with a wall thickness of 3-5mm, a rib width of 6-10mm, and a rib height of 5-15mm. The front joint 2 and the rear joint 3 are made of 0Cr17Ni4Cu4Nb deposited stainless steel, and the standard screws and nuts are all made of 316 stainless steel, thereby ensuring lightweight and structural strength.

[0034] Preferably, the structural components of the utility model are all machined by milling to ensure dimensional accuracy.

[0035] This invention achieves both lightweight design and structural strength. The overall assembly process ensures dimensional accuracy and supports training personnel in tasks such as disassembling, maintaining, and testing suspended objects.

[0036] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
