An integrated solar cell array drive mechanism

Abstract

This invention discloses an integrated solar array drive mechanism, comprising a drive control circuit, a power unit, a position feedback device, and a main shaft. The drive mechanism integrates a drive control circuit consisting of multiple circuit boards with drive and control functions. The drive circuit boards are connected to the power unit of the drive mechanism via internal wires, supplying power and sending control signals to drive the power unit. The control circuit boards are connected to the position feedback device via internal wires, receiving position signals from the position feedback device to determine the current rotation position of the drive mechanism, thus laying the foundation for the solar array to be oriented towards the sun. This invention improves upon previous structures where the drive mechanism and drive controller were separate, overcoming problems such as increased weight and susceptibility to signal interference caused by separate drive mechanisms and controllers, effectively improving the reliability of spacecraft.

Description

Technical Field

[0001] This invention relates to the field of solar power generation devices, and more particularly to an integrated solar cell array drive mechanism. Background Technology

[0002] In recent years, my country's aerospace industry has achieved rapid development. To meet the increasing launch demands of various spacecraft platforms, especially commercial spacecraft platforms, the requirements for spacecraft development cycles have become increasingly stringent. To adapt to the new pace of development, integrated, unified, and platform-based products are receiving increasing attention. Integrated products effectively combine functions that previously required multiple individual units, resulting in a more compact and lighter overall structure. They provide a unified installation structure, simplify product delivery and installation procedures, and streamline the overall cable network of the spacecraft, effectively shortening the overall development cycle of the spacecraft.

[0003] Currently, most drive mechanisms adopt a structure in which the drive mechanism and drive controller are independent of each other. The overall structure is relatively heavy, which increases the complexity of the overall cable network of the spacecraft and has the disadvantage that long-distance signal transmission is easily interfered with. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the purpose of this invention is to provide a novel integrated solar cell array drive mechanism to solve the problems of the prior art, which adopts a separate structure for the drive mechanism and the drive controller, resulting in a heavy overall structure, increased complexity of the spacecraft's overall cable network, and susceptibility to interference during long-distance signal transmission.

[0005] To achieve the above objectives, this application provides an integrated solar cell array drive mechanism, including a mechanical device and a control device;

[0006] A cavity is set inside the drive mechanism to install the drive control circuit of the drive mechanism. The drive control circuit consists of multiple circuit boards with drive and control functions. The circuit boards establish an electrical path with the power device inside the drive mechanism through electrical connectors and wires.

[0007] In one possible implementation, the control device includes a drive control circuit and a feedback device, and the mechanical device includes a drive mechanism power unit.

[0008] The drive control circuit and the feedback device are internally connected by wires. Based on the rotational position signal of the drive mechanism obtained by the position feedback device, the control signal is sent to the drive mechanism power device, and the drive mechanism power device rotates in a certain direction by a certain angle.

[0009] In one possible implementation, the drive control circuit includes two sets of circuits: a primary circuit and a backup circuit. The primary and backup circuits are independent of each other, and the control system sends a command signal to determine whether the primary or backup circuit should operate.

[0010] In one possible implementation, the power unit includes two circuits, a primary circuit and a backup circuit, which are independent of each other and are connected one-to-one with the primary and backup circuits of the drive control circuit. The drive control circuit sends a drive control signal to determine whether the primary or backup circuit of the power unit is to operate.

[0011] In one possible implementation, the position feedback device includes two circuits, a primary circuit and a backup circuit, which are independent of each other and are connected one-to-one with the primary and backup circuits of the drive control circuit. The drive control circuit sends drive control signals to determine whether the primary or backup circuit of the position feedback device should operate.

[0012] In one possible implementation, the drive mechanism further includes an electrical connector that is internally connected to the drive control circuit and externally connected to the electrical connector of the control system for transmitting signals and power.

[0013] Compared with existing technologies, the present invention has at least the following beneficial effects: By adopting the above-mentioned technical solution, the present invention effectively integrates the functions of the drive mechanism and the drive controller, realizing an integrated design of the solar cell array drive mechanism. This design offers advantages such as compact structure, light weight, and high reliability. It overcomes the shortcomings of traditional drive mechanisms, which use separate structures for the drive mechanism and drive controller, resulting in a heavier overall structure, increased complexity of the spacecraft's overall cable network, and susceptibility to interference during long-distance signal transmission. It is applicable to various spacecraft products and has a wide range of applications. Attached Figure Description

[0014] Other features, objects, and advantages of the present invention will become more apparent from the following detailed description of non-limiting embodiments with reference to the accompanying drawings:

[0015] Figure 1 A diagram of an integrated solar cell array drive mechanism provided for an exemplary embodiment of the present invention. Detailed Implementation

[0016] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the protection scope of the present invention.

[0017] Please see Figure 1 , Figure 1 This is a schematic diagram of an integrated solar cell array drive mechanism provided by the present invention. In the diagram: 01 is the electrical connector for docking with the spacecraft, 02 is the drive control circuit, 03 is the position feedback device, 04 is the internal connecting wire of the drive mechanism, and 05 is the power unit of the drive mechanism.

[0018] like Figure 1 As shown in the embodiment, the device includes: an electrical connector 01 for docking spacecraft internally connected to a drive control circuit 02, and an external connector for docking spacecraft externally connected to a mating electrical connector for docking spacecraft. Through the electrical connector 01 for docking spacecraft, the control system inside the spacecraft supplies power to the drive control circuit 02 and sends control command signals, establishing an electrical transmission path; a position feedback device 03 and a drive mechanism power unit 05 are connected to the drive control circuit 02 through an internal connecting wire 04 of the drive mechanism. Through the internal connecting wire 04 of the drive mechanism, the drive control circuit 02 supplies power to the position feedback device 03 and the drive mechanism power unit 05 respectively, obtains the rotational position signal of the drive mechanism from the position feedback device 03, and sends a control signal to the drive mechanism power unit 05. The drive mechanism power unit 05 drives the solar array to achieve the function of solar orientation.

[0019] Furthermore, a cavity is set inside the drive mechanism to install the drive control circuit of the drive mechanism. The drive control circuit consists of multiple circuit boards with drive and control functions. It establishes an electrical path for power supply with the energy system through electrical connectors and wires, and establishes an electrical path for various signal transmission with the control system.

[0020] The drive control circuit establishes an electrical path with the power unit within the drive mechanism via electrical connectors and wires, providing power and transmitting signals to the power unit. The drive control circuit has two independent circuits: a primary circuit and a backup circuit. The control system sends command signals to determine whether the primary or backup circuit operates. Correspondingly, the power unit also integrates primary and backup circuits, which are independent and connected one-to-one with the primary and backup circuits of the drive control circuit. The drive control circuit sends drive control signals to determine whether the primary or backup circuit operates. This design effectively increases the reliability of the drive mechanism.

[0021] The drive mechanism establishes an electrical path with the position feedback device inside the drive mechanism via internal wires. This path powers the position feedback device and retrieves the current rotation angle position information of the drive mechanism from the position feedback device. Complementing the dual-configuration of the drive control circuit, the position feedback device also has dual-configuration, with the primary and backup versions independent of each other. Each backup version is connected to the primary and backup versions of the drive control circuit in a one-to-one correspondence. The drive control circuit sends drive control signals to determine whether the primary or backup version of the position feedback device operates. This design is also intended to increase the reliability of the drive mechanism.

[0022] Specific embodiments of the present invention have been described above. It should be understood that the present invention is not limited to the specific embodiments described above, and those skilled in the art can make various changes or modifications within the scope of the claims, which do not affect the essence of the present invention. Unless otherwise specified, the embodiments and features described in this application can be arbitrarily combined with each other.
