It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
It will be understood that when an element is referred to as being "fixed to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. In contrast, when an element is referred to as being "directly on" another element, there are no intervening elements present. The terms "vertical," "horizontal," "left," "right," and the like are used herein for illustrative purposes only.
As shown in fig. 1, a sliding solar panel deployment mechanism according to an embodiment of the present invention includes: the primary solar cell sailboard support frame 004 is used for installing the primary solar cell sailboard 001;
The second-level solar cell sailboard support frame 003 is slidably arranged on the first-level solar cell sailboard support frame 004 and is used for installing the second-level solar cell sailboard 002;
The driving component 006 is arranged on the primary solar cell panel support frame 004 and is in transmission connection with the secondary solar cell panel support frame 003, and is used for applying driving force to the secondary solar cell panel support frame 003 so as to enable the secondary solar cell panel support frame 003 to move to a position overlapping with the primary solar cell panel support frame 004;
The elastic piece 005 is arranged between the first-stage solar cell sailboard support 004 and the second-stage solar cell sailboard support 003; when the second-stage solar panel bracket 003 is positioned at a position overlapping the first-stage solar panel bracket 004, the elastic member 005 accumulates elastic deformation; when the driving component 006 does not apply driving force to the secondary solar panel bracket 003, the secondary solar panel bracket 003 moves to a position expanding relative to the primary solar panel bracket 004 along the plane of the primary solar panel bracket 004 under the elastic force applied by the elastic member 005.
The primary solar panel support 004 may include a main support and secondary supports disposed on two sides of the main support, and the primary solar panel 001 may be mounted on the secondary supports. Likewise, the secondary solar panel bracket 003 may also include a main support frame and secondary brackets on both sides of the main support frame, and the secondary solar panel 002 may be mounted on the secondary brackets. The main support frame of the primary solar cell panel support frame 004 and the main support frame of the secondary solar cell panel support frame 003 can be matched in a relatively sliding manner so as to realize that the secondary solar cell panel support frame 003 is arranged on the primary solar cell panel support frame 004 in a sliding manner. In addition, a mounting shaft 010 for docking with a satellite may be provided on the primary solar cell panel support 004 or the secondary solar cell panel support 003. Alternatively, the mounting axle 010 is disposed on the main support frame of the primary solar panel support frame 004, and is located at an end of the main support frame of the primary solar panel support frame 004, which is far away from the secondary solar panel support frame 003.
The driving assembly 006 can be constructed in various ways. As one embodiment, the drive assembly 006 includes a drive wheel 061, a drive cable 062, and a drive motor (not shown); the driving motor is arranged on the primary solar cell sailboard supporting frame 004, is in transmission connection with the driving wheel 061 and is used for driving the driving wheel 061 to rotate; one end of a driving rope 062 is connected with a driving wheel 061, and the other end of the driving rope 062 is connected with a two-stage solar cell sailboard supporting frame 003; when the driving wheel 061 rotates in the first direction, the driving cable 062 is wound up on the driving wheel 061.
The driving cable 062 is made of a light-weight and strong material, such as a steel wire rope, so that the weight of the whole solar cell sailboard can be effectively reduced. And the driving wheel 061 and the driving motor, are also selected from the types having excellent performance and light weight. In the process that the driving rope 062 is wound around the driving wheel 061, the driving wheel 061 applies driving force to the two-stage solar panel supporting frame 003 through the driving rope 062, so that the two-stage solar panel supporting frame 003 moves to a position overlapping with the one-stage solar panel supporting frame 004, and when the two-stage solar panel supporting frame 003 moves in place, the driving motor stops driving the driving wheel 061 to rotate towards the first direction.
In a specific use process, the number of turns and the angle of rotation of the driving wheel 061 can be calculated according to the sliding travel of the second-stage solar panel support frame 003 relative to the first-stage solar panel support frame 004, so that the driving motor is controlled to stop driving the driving wheel 061 to rotate towards the first direction, the second-stage solar panel support frame 003 can move accurately in place, and meanwhile excessive stretching of the driving rope 062 is avoided. Or the position sensor can be designed to detect the position of the second-level solar panel support frame 003 relative to the first-level solar panel support frame 004, and when the second-level solar panel support frame 003 is detected to move in place, a stop signal is sent to the driving motor through the controller.
In other embodiments, the driving assembly 006 may further include a driving motor and a driving rod, where two ends of the driving rod are respectively connected to the driving motor and the second-stage solar panel bracket 003, and the driving motor drives the driving rod to move linearly so as to drive the second-stage solar panel bracket 003 to move. Or the drive assembly 006 may have some other structure, as long as the purpose of driving the second stage solar panel support 003 to move to an overlapping position with respect to the first stage solar panel support 004 is achieved.
The elastic member 005 may have various structural forms. As an embodiment, the elastic member 005 is a compression spring; one end of the compression spring is fixed at a first end of the primary solar cell panel support frame 004 (the left end of the primary solar cell panel support frame 004 is shown in fig. 2 and 3), and the other end of the compression spring is fixed on the secondary solar cell panel support frame 003; when the secondary solar panel sail panel support 003 is in a position overlapping the primary solar panel sail panel support 004, the compression spring is compressed. Thus, when the driving component 006 does not apply the driving force to the second-stage solar panel bracket 003, the second-stage solar panel bracket 003 can be unfolded relative to the first-stage solar panel bracket 004 under the action of the elastic force of the compression spring. The compression spring may be replaced by another elastic member 005 having a compressive deformation elastic force.
As another embodiment, the elastic member 005 is a tension spring; one end of the tension spring is fixed at the second end of the primary solar cell panel support frame 004 (the right end of the primary solar cell panel support frame 004 is shown in fig. 2 and 3), and the other end of the tension spring is fixed on the secondary solar cell panel support frame 003; when the secondary solar panel sail panel support 003 is positioned to overlap the primary solar panel sail panel support 004, the tension spring is stretched. Thus, when the driving component 006 does not apply the driving force to the second-stage solar panel bracket 003, the second-stage solar panel bracket 003 can be unfolded relative to the first-stage solar panel bracket 004 under the action of the elastic force of the tension spring. The tension spring can be replaced by other elastic members 005 with tension deformation elasticity.
Referring to fig. 1 to 5, in the sliding solar panel unfolding mechanism of the present embodiment, a structure of a second-stage solar panel support frame 003 is slidably disposed on a first-stage solar panel support frame 004, and before being unfolded, the second-stage solar panel support frame 003 is folded inside the first-stage solar panel support frame 004 under the driving force of a driving component 006 (as shown in fig. 3), so that the second-stage solar panel 002 is overlapped with respect to the first-stage solar panel 001 (as shown in fig. 5). When the driving assembly 006 releases the driving force to the secondary solar panel support 003 during the deployment, the secondary solar panel support 003 is deployed relative to the primary solar panel support 004 under the elastic force of the elastic member 005 (as shown in fig. 2), so that the secondary solar panel 002 is deployed relative to the primary solar panel 001 (as shown in fig. 4).
In this way, the whole solar panel can be reduced in volume during satellite launching, and the solar panel can be unfolded after satellite launching into orbit to ensure power supply to the satellite. In addition, the sliding type unfolding structure is reliable, and the phenomenon of unfolding failure is not easy to occur. And because the elastic force of the elastic piece 005 is mainly relied on during the unfolding, an additional unfolding driving structure is not required to be arranged, and the weight of the whole solar cell sailboard is effectively reduced.
The following specifically describes the implementation process of the sliding solar panel deployment mechanism of the present invention, taking the driving assembly 006 as an example of a structural form including a driving wheel 061, a driving rope 062 and a driving motor.
Referring to fig. 1 to 5, the entire solar cell windsurfing board is docked with the satellite body through the mounting shaft 010 before the satellite is launched; the second stage solar panel sail panel support 003 is in an overlapping state with respect to the first stage solar panel sail panel support 004. After the satellite is launched into orbit, the solar cell panel unfolding mechanism receives the unfolding signal, the driving motor drives the driving wheel 061 to rotate in the direction opposite to the first direction, the driving force on the second-stage solar cell panel supporting frame 003 is relieved by releasing the driving rope 062, and then the second-stage solar cell panel supporting frame 003 and the second-stage solar cell panel 002 are unfolded together relative to the first-stage solar cell panel supporting frame 004 under the elastic force of the elastic piece 005.
In this embodiment, the driving motor drives the driving wheel 061 to roll up and release the driving rope 062, so that the speed of the two-stage solar panel support 003 is uniform relative to that of the one-stage solar panel support 004 in the moving process, smoothness of the unfolding action of the whole solar panel unfolding mechanism is guaranteed, and influences on the postures of the whole satellite and the spacecraft are reduced to the greatest extent.
Referring to fig. 2 and 3, as one embodiment, the driving cables 062 are two; the driving wheel 061 has two winding grooves in which the two driving ropes 062 can be wound up, respectively. The two driving ropes 062 may be symmetrically distributed on two sides of the main support frame with a central axis of the main support frame of the first-stage solar panel support frame 004 as an axis. The two driving ropes 062 are used for driving the two-stage solar cell sailboard support frames 003 to move simultaneously, so that the stress of the two-stage solar cell sailboard support frames 003 when being unfolded is uniform, the unfolding resistance of the solar cell sailboard is reduced, and the safe unfolding of the solar cell sailboard is ensured. And utilize two coiling grooves to roll first two drive ropes 062 respectively, avoid two drive ropes 062 to roll up the interference each other when time, guarantee the reliable operation of solar cell panel.
As an implementation manner, a supporting rod 007 is arranged on the primary solar panel supporting frame 004, pulleys are arranged at two ends of the supporting rod 007, and two driving ropes 062 are respectively abutted with the two pulleys. The pulleys at two ends of the supporting rod 007 are respectively abutted with the two driving rope cables 062, so that independent operation of the two driving rope cables 062 is guaranteed, a certain supporting effect is achieved on the driving rope cables 062, and meanwhile, the pulleys are beneficial to smooth movement of the driving rope cables 062.
As an implementation manner, the sliding solar panel unfolding mechanism further includes a pulley assembly 008, the pulley assembly 008 is disposed on the second-stage solar panel support 003, and one end of the driving rope 062 connected with the second-stage solar panel support 003 bypasses the pulley assembly 008 and is fixed on the second-stage solar panel support 003.
Assuming that the primary solar panel support 004 has opposite first and second ends (left and right ends of the primary solar panel support 004 as shown in fig. 2 and 3), the secondary solar panel support 003 has opposite third and fourth ends (left and right ends of the secondary solar panel support 003 as shown in fig. 2 and 3), the third end being closer to the first end than the fourth end. The driving motor and the driving wheel 061 are disposed at the first end of the primary solar panel support frame 004, and one end of the driving rope 062 connected with the secondary solar panel support frame 003 may be fixed at the third end, or the fourth end, or a position between the third end and the fourth end of the secondary solar panel support frame 003. In this embodiment, the pulley assembly 008 may include a set of pulleys, where the set of pulleys is disposed at the fourth end, and one end of the driving rope 062 connected with the second-stage solar panel bracket 003 bypasses the pulley assembly 008 and is fixed at the third end of the second-stage solar panel bracket 003. Like this, can guarantee that second grade solar cell sailboard support frame 003 is when receiving the drive power, whole atress is even, and not only a certain atress, can effectively reduce driving motor's drive power simultaneously.
In one embodiment, the pulley assembly 008 may further include a plurality of sets of pulleys, and the plurality of sets of pulleys are arranged at intervals between the third end and the fourth end of the second-stage solar panel bracket 003. One end of the driving rope 062 connected with the second-stage solar cell sailboard support frame 003 bypasses a pulley close to the fourth end and is fixed to the third end of the second-stage solar cell sailboard support frame 003, and other pulleys are in rolling contact with the driving rope 062.
Referring to fig. 2 and 3, as an implementation manner, a chute 041 is provided on the primary solar panel bracket 004, and the secondary solar panel bracket 003 is slidably disposed in the chute 041. When the secondary solar panel support 003 is positioned at an overlapping position with respect to the primary solar panel support 004, the secondary solar panel support 003 is almost completely received in the chute 041 of the primary solar panel support 004 to minimize the volume of the entire solar panel prior to satellite launch (as shown in fig. 5).
Further, a sliding rod 031 in sliding fit with the sliding groove 041 is disposed on the two-stage solar panel support 003, the sliding rod 031 is perpendicular to the extending direction of the sliding groove 041, and two ends of the sliding rod 031 are respectively abutted with two side walls of the sliding groove 041. Through setting up the slide bar 031 of length and the width adaptation of spout 041, guaranteed second grade solar cell panel support 003 and for the gliding stability of first grade solar cell panel support 004, prevent the phenomenon of violent wobbling when the relative slip appears. Meanwhile, due to the existence of the sliding rod 031, the width of the sliding fit part of the two-stage solar panel support frame 003 and the one-stage solar panel support frame 004 except the sliding rod 031 can be reduced, and then the weight of the whole solar panel can be effectively reduced.
In other embodiments, the primary solar panel bracket 004 and the secondary solar panel bracket 003 can be slidably connected by way of a sliding rail and a sliding block. Or the sliding connection is realized by a slideway and a roller.

The sliding connection assembly 009 can be used to guide and assist the sliding of the two-stage solar panel support 003 and the one-stage solar panel support 004. For example, in the embodiment in which the second-stage solar panel support frame 003 is slidably disposed in the sliding groove 041 of the first-stage solar panel support frame 004, the sliding connection assembly 009 is installed in the space between the second-stage solar panel support frame 003 and the side wall of the sliding groove 041, and has a supporting effect on the part of the second-stage solar panel support frame 003 except for the sliding bar 031, so as to ensure the sliding stability of the second-stage solar panel support frame 003, and on the other hand, reduce the sliding friction force between the second-stage solar panel support frame 003 and the sliding groove 041, which is beneficial to the smoothness of the sliding of the second-stage solar panel support frame 003.
Optionally, slip joint assembly 009 comprises a plurality of balls; two surfaces of the primary solar cell sailboard support 004 and the secondary solar cell sailboard support 003 which are matched with each other are provided with guide grooves, and a plurality of balls are arranged in the guide grooves. The plurality of balls are beneficial to the smoothness and accuracy of the relative sliding of the two-stage solar cell panel support 003 and the one-stage solar cell panel support 004. In other embodiments, the slip connection assembly 009 may also include a plurality of rollers.
The embodiment of the invention also provides a unfolding method of the sliding solar cell sailboard unfolding mechanism, which comprises the following steps:
