Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail and completely with reference to the following embodiments and accompanying drawings. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In the prior art, the solar panel is folded and unfolded through a spring structure. When the satellite is on the ground, the spring structure can be manually extruded to fold the solar panel. In space, the spring structure can be controlled to elastically stretch, so that the solar panel is unfolded in a pop-up mode. It is clear that in space it is not possible to recompress the spring structure by manual operations like those on the ground. This means that the solar panels cannot be folded up again after space deployment. In some scenarios, the solar panel may be required to be folded again. The spring structure in the prior art is difficult to meet the requirements at this time.
In addition, the spring structure can generate certain impact force in the process of unfolding the solar panel in an ejecting mode. In the vacuum weightlessness environment in space, any tiny impact force can affect the attitude of the satellite, thereby affecting the stability of the satellite operation. The prior art also lacks a structure for smoothly unfolding and folding the solar panel.
In view of the above, the present invention provides a solar panel, as shown in fig. 1 to 2. Figure 1 is a top view of a solar panel in a folded state. Fig. 2 is a cross-sectional view of fig. 1 taken along the dotted line. In this embodiment, solar panel includes: motor 303, drive assembly 301, support column 501 and solar module 200.
Wherein the motor 303 is connected to the support column 501 through the driving assembly 301. The support column 501 is used for supporting the whole structure of the solar panel and also used for driving the solar module 200 to be unfolded and folded through the self expansion and contraction. The inside of the support column 501 is a nested structure comprising at least two sleeves that are threadedly connected. In this embodiment, the support column 501 comprises a first sleeve 101 and a second sleeve 102, and the first sleeve 101 is nested outside the second sleeve 102. The inner surface of the first sleeve 101 has a relatively fixed first connector 105. The first connecting member 105 may be made of metal, and may have a spherical shape. The outer surface of the second sleeve 102 has a threaded groove. The first connecting member 105 is fitted in the threaded groove of the second sleeve.
In other embodiments, the support column 501 may include a greater number of threaded sleeves, and the connection relationship may be similar to the first sleeve 101 and the second sleeve 102 described above. Other situations are not described in the embodiment. But obviously such a situation is under the overall technical solution of the present invention.
The support column 501 includes a mount at both ends for fixing the solar module 200. In this embodiment, a first end of the first sleeve 101 is connected to the first seat 110, and a second end of the first sleeve 101 is connected to the second seat 107. The first end of the second sleeve 102 is disposed within the first sleeve 101 and the second end of the second sleeve 102 is coupled to the third seat 108.
The solar module 200 is the core component in a solar panel, which is essentially a so-called solar photovoltaic, or solar fin, in the art. The material of the solar module 200 is typically crystalline silicon, which functions to absorb solar energy and convert the solar energy into electrical energy. The solar module 200 includes at least two individual plates, and one individual plate can be considered as a set of fins made of crystalline silicon. The single plates are flexibly connected, so that the single plates can be folded or unfolded. The solar module 200 is connected to the support of the support column 501.
In this embodiment, the solar module 200 comprises 2 individual sheets, including a first individual sheet 201 and a second individual sheet 202. A first side of the first monolithic plate 201 is connected to the first support 110 and a second side of the first monolithic plate 201 is connected to the second support 107. The second side of the first monolithic plate 201 is flexibly connected to the first side of the second monolithic plate 202. The second side of the second monolithic plate 202 is attached to the third mount 108.
In the solar panel, the motor 303 is used for controlling the support column 501 to stretch and retract, so as to drive the solar module 200 to unfold and fold. Specifically, the motor 303 will control the sleeve rotation of the support column 501 via the driving assembly 301, so that the support column 501 will achieve the effect of lengthening or shortening under the effect of the screw rotation. When the supporting column 501 extends, the distance between the supporting bases increases, so that the single plates fixed on the supporting bases are driven to expand. When the supporting column 501 is shortened, the distance between the supports is reduced, and the single plates fixed on the supports are driven to be folded. In this embodiment, the specific principle of this process can be described as follows:
the drive assembly 301 is connected to the first sleeve 101 of the support column 501. The drive assembly 301 may specifically be a belt drive assembly. The pulley in the belt turning assembly guides the belt to roll under the action of the motor 303. The belt is sleeved on the outer surface of the first sleeve 101. When the belt rolls, the first sleeve 101 can be driven to rotate by friction. The motor 303 should be a bidirectional motor, i.e. capable of outputting torque in both forward and reverse directions. That is, the motor can control the first sleeve 101 to rotate in the first direction or the second direction through the driving assembly 301. The first direction and the second direction are opposite directions.
When the first sleeve 101 is rotated in a first direction, the relatively fixed first connector 105 will rotate with the first sleeve 101. That is, the first connector 105 will move in the first direction within the threaded slot of the second sleeve 102. Under the action of the screw thread, the second sleeve 102 will move out of the first sleeve 101, i.e. to the right in fig. 1-2. In other words, the second sleeve 102 extends from the first sleeve 101, causing the support column 501 to elongate.
When the first sleeve 101 is rotated in the second direction, the above is reversed. The first connecting member 105 moves in the second direction in the thread groove of the second sleeve 102, so that the second sleeve 102 moves towards the inside of the first sleeve 101 under the action of the thread, i.e. to the left in fig. 1-2. In other words, the second sleeve 102 is retracted into the first sleeve 101, causing the support column 501 to shorten.
In addition, the present embodiment may further include a first trigger switch 404 and a second trigger switch 401. Also, the first trigger switch 404 has a matching first trigger 403, and the second trigger switch 401 has a matching second trigger 402.
Specifically, when the supporting column 501 extends to reach a first preset position, the first trigger 403 contacts the first trigger switch 404, thereby triggering the first trigger switch 404, so that the motor 303 stops controlling the sleeve of the supporting column 501 to rotate through the driving assembly 301. At which point the elongation of the support column 501 is to its limit. That is, the first preset position represents an extreme position of elongation of the support column 501.
Conversely, when the supporting column 501 is shortened to reach the second preset position, the second trigger 402 contacts the second trigger switch 401, and triggers the second trigger switch 401, so that the motor 303 stops controlling the sleeve of the supporting column to rotate through the driving assembly 301. In fig. 1, a state is shown in which the second trigger 402 is in contact with the second trigger switch 401 when the supporting column 501 is shortened to the limit. At this point the shortening of the support column 501 is to its limit. That is, the second preset position represents the limit position of shortening of the support column 501.
Through the first trigger switch 404 and the second trigger switch 401, the present embodiment further realizes the automatic control of the extension and retraction of the support column 501, and the motor operation is automatically stopped when the support column 501 extends or retracts to a preset position.
According to the technical scheme, the beneficial effects of the embodiment are as follows: the solar panel drives the sleeve connected with the support column through the screw thread to rotate through the motor so as to extend or shorten the support column, so that the solar module is driven to be unfolded when the support column is extended, and the solar module is driven to be folded when the support column is shortened; the solar module can be completely controlled to be unfolded and folded, and the technical problem that the solar module cannot be folded again in the space in the prior art is solved; the support column is elongated or shortened under the screw thread effect, and the period is moved gently, does not produce the impact force, also can not influence the gesture and the operating stability of satellite.
It is appreciated that in the above embodiments, the support column 501 may include a greater number of sleeves that are threadably engaged, and a greater number of individual panels may be included in the solar module 200. In most cases, the number of sleeves and the number of single plates may be equal, i.e. one single plate is fixed to the support of one sleeve end.
In the embodiment shown in FIGS. 3-4, a specific embodiment comprising 3 sleeves and 3 individual plates is further disclosed. Other solutions including a larger number of sleeves and single plates can be obtained by analogy with the same principle. Obviously, all the solutions available by analogy are included in the coverage of the whole technical solution of the present invention, and the present invention does not need to be exhaustive.
In this embodiment, fig. 3 is a top view of the solar panel in a folded state. Fig. 4 is a cross-sectional view of fig. 3 taken along the dotted line. Solar panel includes in this embodiment equally: motor 303, drive assembly 301, support column 501 and solar module 200.
Different from the embodiment shown in fig. 1-2, the support column 501 in this embodiment includes a first sleeve 101, a second sleeve 102, and a third sleeve 103. The nesting arrangement between the first sleeve 101 and the second sleeve 102 is consistent with the previous embodiments. Further, the second sleeve 102 is nested outside the third sleeve 103. The inner surface of the second sleeve 102 has a relatively fixed second connector 106. The second connecting member 106 may be made of metal, and may be spherical. The outer surface of the third sleeve 103 has a threaded groove. The second connecting member 106 is inserted into the threaded groove of the third sleeve. That is, the nesting configuration between the inner and outer sleeves is uniform.
The support column 501 includes a mount at both ends for fixing the solar module 200. In this embodiment, a first end of the first sleeve 101 is connected to the first seat 110, and a second end of the first sleeve 101 is connected to the second seat 107. The first end of the second sleeve 102 is disposed within the first sleeve 101 and the second end of the second sleeve 102 is coupled to the third seat 108. A first end of the third sleeve 103 is disposed within the second sleeve 102 and a second end of the third sleeve 103 is coupled to the fourth seat 109.
The solar module 200 comprises 3 individual sheets, including a first individual sheet 201, a second individual sheet 202 and a third individual sheet 203. A first side of the first monolithic plate 201 is connected to the first support 110 and a second side of the first monolithic plate 201 is connected to the second support 107. The second side of the first monolithic plate 201 is flexibly connected to the first side of the second monolithic plate 202. The second side of the second monolithic plate 202 is attached to the third mount 108. The second side of the second monolithic plate 202 is flexibly connected to the first side of the third monolithic plate 203. The second side of the third monolithic plate 203 is attached to the fourth mount 109.
The drive assembly 301 is connected to the first sleeve 101 of the support column 501. Under the action of the motor 303, the driving assembly 301 will drive the first sleeve 101 to rotate. The motor 303 should be a bidirectional motor, i.e. capable of outputting torque in both forward and reverse directions. That is, the motor can control the first sleeve 101 to rotate in the first direction or the second direction through the driving assembly 301. The first direction and the second direction are opposite directions.
When the first sleeve 101 is rotated in a first direction, the relatively fixed first connector 105 will rotate with the first sleeve 101. That is, the first connector 105 will move in the first direction within the threaded slot of the second sleeve 102. Under the action of the screw thread, the second sleeve 102 and the third sleeve 103 will move out of the first sleeve 101. When the first connecting member 105 moves to the first end of the threaded groove of the second sleeve 102 along the first direction, the first connecting member cannot move any further. At this time, the first sleeve 101 and the second sleeve 102 are locked, and the second sleeve 102 will rotate along with the first sleeve 101 in the first direction. After the second sleeve 102 starts to rotate in the first direction, the second connection member 106 is moved in the first direction in the threaded groove of the third sleeve 103. Under the action of the screw thread, the third sleeve 103 will continue to move out of the second sleeve until the support column 501 is extended to the limit position.
When the first sleeve 101 is rotated in the second direction, the above is reversed. The movement of the first connector 105 in the second direction in the threaded groove of the second sleeve 102 causes the second sleeve 102 to move under the action of the threads into the first sleeve 101. When the first connecting member 105 moves to the second end of the threaded groove of the second sleeve 102 along the second direction, the first connecting member cannot move any further. At this time, the first sleeve 101 and the second sleeve 102 are locked, and the second sleeve 102 rotates along with the first sleeve 101 in the second direction. After the second sleeve 102 starts to rotate in the second direction, the second connection member 106 is moved in the second direction in the threaded groove of the third sleeve 103. Under the action of the screw thread, the third sleeve 103 moves inwards of the second sleeve until the support column 501 is shortened to the limit position.
In this embodiment, a specific embodiment including 3 sleeves and 3 single plates, a nesting relationship between the sleeves, and an operation principle of achieving extension and contraction between the sleeves are further described. Therefore, other schemes of more sleeves and single plates can be obtained by analogy in the same way.
In addition, the present application further includes a satellite. The satellite is characterized in that the solar panel described in the above embodiment is carried, and the solar panel can be controlled to be unfolded or folded in the manner described in the above embodiment. Therefore, the satellite also realizes the complete control of the unfolding and folding of the solar component, and solves the technical problem that the solar component cannot be folded again in the space in the prior art; the support column is elongated or shortened under the screw thread effect, and the period is moved gently, does not produce the impact force, also can not influence the gesture and the operating stability of satellite.
