AI Technical Summary
[0002]飞机上用于飞行操纵系统的支座结构有扭力盒和操纵支座接头，为了将载荷传到机体结构上，一般的操纵支座接头需提前布置固定位置，借用机体结构作连接区，但是如果机体结构上近距离内没有合适的连接点位，就需要专门布置连接结构用于连接操纵支座接头和机体结构，连接结构的形式往往采用扭力盒的形式，可以传递剪力、弯矩、扭矩，扭力盒应当是封闭的结构，否则会影响抗扭能力，但这又带来了重量及空间的代价问题，通常难以接受
本实用新型提出一种单方向受载的操纵支座结构，该支座结构结合操纵载荷特点，通过接头和隔板将载荷传递到机体结构上，极大减少了设计重量和占用空间，可以根据实际需求选择连接件，要求可拆卸时可以将铆钉更换为螺栓连接，也可采用增材制造技术实现隔板和接头的一体化设计。采用C型梁式接头，最大程度上提升了支座的抗弯能力，接头可以根据操纵系统要求可以布置在隔板间的任意位置。该操纵支座结构形式简单，适应性强，可靠性高，能够有效解决操纵支座无固定连接位置的问题，且重量代价较小，实用性较好，易于推广应用，是一种创新的设计，具有较大的价值。

Abstract
Description
Technical Field
[0001] This utility model belongs to the field of aircraft design technology, and relates to the design technology of aircraft control support structure, specifically to a control support structure subjected to load in one direction. Background Technology
[0002] The support structures used for flight control systems on aircraft include torque boxes and control support joints. In order to transfer the load to the airframe structure, the control support joints generally need to be fixed in place in advance, using the airframe structure as the connection area. However, if there is no suitable connection point in the airframe structure in the near distance, a special connection structure is required to connect the control support joints and the airframe structure. The connection structure often takes the form of a torque box, which can transmit shear force, bending moment, and torque. The torque box should be a closed structure, otherwise it will affect the torsional resistance. However, this brings the problem of weight and space costs, which is usually unacceptable.
[0003] Following this approach, a new control support structure is needed that can transmit control loads while minimizing weight and space costs, and ensuring the trajectory path of the control system. Utility Model Content
[0004] The purpose of this invention is to solve the problem of effectively transmitting the control load to the body structure. This invention provides a control support structure for unidirectional load. While transmitting unidirectional load, this invention minimizes weight and space costs and is suitable for the design of control support structures for unidirectional load.
[0005] Technical solution A unidirectional load-bearing control support structure includes a joint, an upper partition, and a lower partition. The joint includes a lug end and a connecting end. The upper and lower partitions are respectively disposed on the upper and lower sides of the connecting end. The upper and lower partitions are respectively connected to the body structure. The lug end of the joint is connected to the control system. The load of the control system can be unidirectionally transmitted to the body structure through the joint and the upper and lower partitions.
[0006] Furthermore, it also includes connectors, with the upper and lower partitions fixed to the upper and lower sides of the connecting end respectively via connectors.
[0007] Furthermore, the upper and lower partitions are fixed to the upper and lower sides of the connecting end by rivets and bolts, respectively.
[0008] Furthermore, the connector, upper partition, and lower partition are integrally molded.
[0009] Furthermore, the joint is a C-type beam joint.
[0010] Furthermore, the connection structure between the upper and lower partitions and the body structure is set according to the load size and actual needs.
[0011] Beneficial effects This invention proposes a unidirectional load-bearing control support structure. This support structure, considering the characteristics of the control load, transfers the load to the machine body structure through joints and partitions, significantly reducing design weight and space occupation. Connectors can be selected according to actual needs; for detachable applications, rivets can be replaced with bolts, or additive manufacturing technology can be used to achieve an integrated design of the partitions and joints. The use of C-beam joints maximizes the support's bending resistance, and the joints can be placed at any position between partitions according to the control system requirements. This control support structure is simple, highly adaptable, and reliable, effectively solving the problem of no fixed connection position for control supports. It also has a low weight cost, good practicality, and is easy to promote and apply. It is an innovative design with significant value. Attached Figure Description
[0012] Figure 1 This is a structural diagram of a control support subjected to load in one direction; Among them, 1-connector, 2-upper partition, 3-lower partition, 4-connector.
[0013] Figure 2 This is a diagram of the connector. Detailed Implementation
[0014] like Figure 1 As shown, this utility model proposes a unidirectional load-bearing control support structure, including a connector 1, an upper partition 2, and a lower partition 3. The connector 1 includes a lug end and a connecting end. The upper partition 2 and the lower partition 3 are respectively disposed on the upper and lower sides of the connecting end. The upper partition 2 and the lower partition 3 are respectively connected to the body structure. The lug end of the connector 1 is connected to the control system. The load of the control system can be unidirectionally transmitted to the body structure through the connector 1 and the upper partition 2 and the lower partition 3.
[0015] This utility model proposes a unidirectional load-bearing control support structure for aircraft. A connector is used to connect the joint to a bulkhead, and then, depending on actual needs, an appropriate connection method is selected to connect the bulkhead to the fuselage structure. The control system load can be transferred to the joint via a tie rod, and then from the joint to the fuselage structure via the bulkhead. The tie rod and the joint are connected by bolts.
[0016] The connection structure between the partition and the body can be changed according to the load size and actual needs. Figure 1 The partition plate is directly attached to the body structure. The extended part of the body needs to be connected to the partition plate. If the load is too large, the lug type connection can be selected. The lugs can be integrally machined on the left and right sides of the partition plate.
[0017] The unidirectional load-bearing control support structure proposed in this utility model has a clear principle, simple structure, strong adaptability, and high reliability. It can effectively solve the problem of the lack of a fixed connection position for the control support, and has a low weight cost. It is practical, easy to promote and apply, and is an innovative design with great value.
