The deployment mechanism usually contains multiple key components, among which the compression belt is a key component, which is used to compress the structural parts during the deployment of the spacecraft to ensure the correct position and reliability of each component. In order to effectively realize the function of the deployment mechanism, the compression force of the compression belt must be accurately controlled and adjusted.

[0003] At present, the existing compression belt loading devices have some technical bottlenecks to a certain extent.

It is difficult for traditional loading devices to achieve precise adjustment of the clamping force of the compression belt, which may lead to problems such as inaccurate structural displacement and component position deviation during the deployment of the spacecraft, thereby affecting the normal operation of the spacecraft. Some devices are prone to wear and failure during long-term use, reducing the reliability and life of the entire deployment mechanism. The loading device may be affected by external environmental factors, resulting in changes in the clamping force, thereby affecting the stability of the spacecraft.

[0026] Figure 1 It is a schematic diagram of a compression force loading device of a compression belt according to an embodiment of the present invention. DETAILED DESCRIPTION

[0027] The present invention will be further described below in conjunction with the embodiments.

[0028] In order to improve the practicality of the entire loading device, the present invention aims to design a simple-to-operate compression belt pressure loading device for the deployment mechanism of a spacecraft, so that the loading of the compression belt and the release process of the deployment mechanism are more intuitive and controllable. By introducing advanced control technology and material engineering, the loading device can achieve high-precision control of the compression force of the compression belt, ensuring the reliability and stability of the deployment mechanism. At the same time, the loading device of the present invention is more durable, which can effectively extend the service life of the spacecraft and improve the performance level of the entire system.

[0029] like Figure 1 As shown, the device provided by the present invention includes a mounting base 1, a clamping lever 2, a clamping belt 3, a clamping belt cover plate 4, a guide rope ring 5, a pull rope tensioning seat 6, a release leaf spring 7, and a loading device; the clamping lever 2, the clamping belt 3, the clamping belt cover plate 4, the guide rope ring 5, the pull rope tensioning seat 6, the release leaf spring 7, and the loading device can be used on one side of the spacecraft deployment mechanism, and can also be used in pairs on both sides of the spacecraft deployment mechanism.

[0030] The mounting base 1 is used for fixed installation on the surface of the spacecraft, providing firm support for the clamping force loading device, and serving as a bottom limit support for the deployment mechanism, to ensure that the entire system can remain stable and firm when installed on the spacecraft.

[0031] The clamping lever 2 adopts a two-section structure, one section is the clamping end, which is used to connect with the lower end of the clamping belt to clamp the clamping belt 3, and the other section is the loading end, which is tensioned by a pull rope to achieve precise adjustment of the clamping belt; the middle part connecting the two sections is connected to the support leg of the mounting base 1 through a rotating shaft, which ensures that the appropriate clamping force can be flexibly adjusted and maintained under different working conditions.

[0032] The pull rope tensioning seat 6 is fixedly mounted on the surface of the spacecraft; the pull rope tensioning seat adjusts the compression lever by tensioning the pull rope, thereby adjusting the strength of the compression belt. The operator can adjust the entire loading device by a simple pull rope action.

[0033] The guide rope ring 5 is fixed on the rope tensioning seat 6, and the guide rope ring 5 is located above the loading end of the clamping lever 2; the clamping lever 2 is connected to the lower end of the clamping belt 3 to enhance the support for the deployment mechanism and improve the stability of the entire system.

[0034] There are two compression belt cover plates 4, which are located above the compression belt and clamped on both sides of one end of the compression belt to protect the compression belt from external interference and help fix the compression belt to ensure that it is not damaged during loading.

[0035] One end of the compression band and the compression band cover plate 4 clamped on both sides are fixed to the spacecraft deployment mechanism by screws to ensure that the connection meets the design requirements of the mechanism; the other end of the compression band is connected with the compression end of the compression lever 2 and is tightly fixed by the action of the compression lever; the design of the compression band enables it to provide reliable supporting force in the deployment mechanism and maintain the structural rigidity of the mechanism.

[0036] One end of the pull rope is fixed to the loading end of the pressing lever 2, and the other end passes through the guide rope ring 5 and is connected to the loading device;

[0037] The release leaf spring 7 has one end fixedly mounted on the base 1 and the other end connected to the loading end of the clamping lever 2. In the initial state, the release leaf spring 7 is in a stretched state to generate a downward preload. As part of the release mechanism, when the pull rope is disconnected, the release leaf spring releases the clamping lever, causing it to release the clamping belt and achieve safe release of the deployment mechanism.

[0038] Preferably, the clamping end of the clamping lever 2 and the clamping belt 3 are connected by a hook-type structure, with the hook of the clamping end of the clamping lever 2 facing downward and the hook of the clamping belt 3 facing upward.

[0039] Preferably, in the loading state, the loading end of the clamping lever 2 is pulled upward by the pull rope, and the clamping end of the clamping lever 2 moves downward to clamp the clamping belt 3;

[0040] In the released state, the tension of the pull rope on the loading end of the clamping lever 2 contacts, releasing the leaf spring 7 to generate a downward pulling force, and the clamping end of the clamping lever releases the pressure on the clamping belt.

[0041] Preferably, the compression belt 3 is in a curled state when not compressed.

[0042] Preferably, the holes on the compression belt cover plate 4 for passing the screws are oblong holes.

[0043] The rope tensioning seat 6 and the rope guide ring 5 are used to guide the direction of the rope;

[0044] Preferably, the rope tensioning seat 6 is provided with an oblong hole for pre-tightening the rope, and the rope tensioning degree can be adjusted by moving the installation position.

[0045] Preferably, the pull rope is made of steel wire rope.

[0046] Preferably, the material of the pressing lever is titanium alloy.

[0047] This design enables the loading device to adapt to different working conditions and ensures that the pressing force applied to the deployment mechanism is just right. Through this technical solution, the present invention can achieve stable and precise control of the deployment mechanism, while improving adaptability and ease of operation, solving a series of technical problems existing in traditional loading devices and providing an efficient and reliable solution for the deployment mechanism of spacecraft.

[0048] The following is the working process of the compression belt compression force loading device in the present invention, including the following steps:

[0049] Step 1: Fix the base, compression belt, compression belt cover, compression lever and other parts on the star body correctly.

[0050] Step 2: Connect the clamping lever: Connect the clamping lever to the lower end of the clamping belt to increase support for the deployment mechanism and enhance the stability of the entire system.

[0051] Step 3, tensioning the pull rope, through the pull rope tensioning seat, tensioning a section of the clamping lever. This step can adjust the strength of the clamping belt by operating the pull rope, so that it can provide appropriate clamping force in different situations.

[0052] Step 4: Maintaining the working state: In this stage, the loading device will maintain the compression state of the deployment mechanism and maintain the support force of the deployment mechanism. This helps to ensure that the deployment mechanism of the spacecraft can maintain the predetermined structural rigidity and stability.

[0053] Step 5: Release: When the deployment mechanism needs to be released, the pull cord is disconnected by operating the release leaf spring. Under the action of the release leaf spring, the compression lever releases the compression belt, thereby releasing the deployment mechanism. The deployment mechanism can thus be freely deployed or folded. Under the action of the release leaf spring, the compression lever releases the compression belt, thereby safely releasing the deployment mechanism.

[0054] The specific implementation of the present invention realizes precise control and adjustable release of the deployment mechanism of the spacecraft by reasonably configuring key components such as the compression belt 3, the compression lever 2, the pull rope tensioning seat 6, the guide rope ring 5, etc., and has high operability, stability and adaptability.

[0055] In summary, the present invention relates to a compression force loading device for a compression belt of a spacecraft deployment mechanism, the innovation of which is to achieve highly accurate control of the compression belt by cleverly fixing the compression belt to the side of the aircraft deployment mechanism, combined with the fixation of the leaf spring and the adjustment of the tension wire. Specifically, one end of the leaf spring is connected to the compression belt, and the other end is fixed to the mechanism, and this device can effectively maintain the correct position of the compression belt.

[0056] In the present invention, the tensioning belt is compressed quickly and accurately by combining the tensioning wire with the leaf spring and a simple tensioning wire tensioning mechanism. At the same time, the tensioning wire is released by the breaker during release, and the mechanism is released under the action of the leaf spring, thereby ensuring the safety and controllability of the release process.

[0057] In addition, the design of the present invention takes into account the stability and durability of the system, ensuring that it is not prone to wear and failure during long-term use. The entire loading device is easy to operate and efficient, and can be applied to various spacecraft deployment mechanisms, providing reliable structural support for spacecraft during deployment. Through the above innovations, the present invention not only improves the performance level of the system, but also demonstrates significant superiority in practical applications.

[0058] Combining the above advantages, the loading device of the present invention has significant innovative advantages in improving the performance and reliability of the deployment mechanism of spacecraft, and is expected to have a positive impact in the field of aerospace technology.
