[0034] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. Preferred embodiments of the present invention are provided in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0036] A satellite communication box, such as Figure 1 As shown, it includes a box 100, a base 200, a lifting assembly 300 and an antenna assembly 400.

[0037] The base 200 is disposed in the box 100 and is used to support the antenna assembly 400. The base 200 is provided with a support arm 210 and a support arm driving assembly 220. The support arm 210 is used to control the movement of the antenna assembly 400 on the pitch axis, and the support arm driving assembly 220 is used to drive the rotation angle of the support arm 210. Specifically, one end of the support arm 210 is connected to the antenna assembly 400, and the other end is connected to the support arm driving assembly 220; the support arm driving assembly 220 is fixed on the base 200.

[0038] The lifting assembly 300 is disposed in the box body 100 and is used to control the lifting and lowering of the base 200 in the vertical direction. Specifically, the lifting assembly 300 is connected to the box body 100 and the base 200 respectively.

[0039] The antenna assembly 400 has two states: folded and unfolded. Figure 2 As shown, it includes a first antenna 401 , a second antenna 402 and a retractable driving component 403 .

[0040] The cross-sections of the first antenna 401 and the second antenna 402 are both semicircular in design and have the same radius, and the two can form an arc surface when combined. When the antenna assembly 400 is in a folded state, the first antenna 401 and the second antenna 402 are in a back-to-back structure; when the antenna assembly 400 is in an unfolded state, the first antenna 401 and the second antenna 402 are combined to form an arc surface, which is used as a parabolic antenna. The parabolic antenna can be a forward-fed antenna or an offset-fed antenna. In this embodiment, the parabolic antenna is optionally an offset-fed antenna. Specifically, one side of the first antenna 401 is hinged to one side of the second antenna 402 by a hinge.

[0041] The retractable drive member 403 is used to control the switching between the unfolded and folded states of the antenna assembly 400, that is, to control the relative position change of the first antenna 401 and the second antenna 402. Specifically, the retractable drive member 403 is connected to the back of the first antenna 401 and the back of the second antenna 402, respectively. Optionally, the retractable drive member 403 can be fixed on the back of the first antenna 401 and connected to the back of the second antenna 402; it can also be fixed on the back of the second antenna 402 and connected to the back of the first antenna 401, and the connection with the first antenna 401 and the second antenna 402 can also be achieved by other means.

[0042] When the antenna assembly 400 is changed from the folded state to the unfolded state, and the first antenna 401 is fixed, the retractable driving member 403 drives the second antenna 402 to perform a 180° flipping motion, so that one side of the first antenna 401 is flush with and in contact with one side of the second antenna 402, forming an arc surface; when the antenna assembly 400 is changed from the unfolded state to the folded state, and the first antenna 401 is fixed, the retractable driving member 403 drives the second antenna 402 to perform a 180° flipping motion in the opposite direction, so that one side of the first antenna 401 is disconnected from one side of the second antenna 402, and the first antenna 401 and the second antenna 402 are only hinged, and the first antenna 401 and the second antenna 402 are back-to-back structures. When the second antenna 402 is fixed, the movement of the first antenna 401 is consistent with the movement of the second antenna 402, and will not be repeated here.

[0043] The retractable driving component 403 may be a driving component such as an electric cylinder or a pneumatic cylinder.

[0044] In the satellite communication box, the antenna can be switched between the unfolded and folded states through the retractable drive member 403, and the movement in the pitch axis direction can be achieved through the support arm 210 and the support arm drive assembly 220, without the need to manually assemble the antenna; at the same time, the base 200 can be automatically raised or lowered through the lifting assembly 300, without the need to manually take out the communication equipment in the box 100. The satellite communication box shortens the time for setting up, opening and retracting the communication equipment, and the folding design makes it smaller in size and more convenient to carry and use.

[0045] In one embodiment, the lifting assembly 300 includes three or more telescopic driving members, one end of which is hinged to the box body and the other end is hinged to the base. In this embodiment, there are three telescopic driving members, such as Figure 3 As shown, they are respectively a first telescopic drive member 301, a second telescopic drive member 302 and a third telescopic drive member 303, and the three telescopic drive members are distributed in a triangular shape on the side of the base 200. Among them, the first telescopic drive member 301 is arranged in the middle of one side of the base 200; the second telescopic drive member 302 is arranged on one side adjacent to the side, and is located at one end away from the first telescopic drive member 301; the third telescopic drive member 303 is arranged on the other side adjacent to the side, and is located at one end away from the first telescopic drive member 301; the second telescopic drive member 302 and the third telescopic drive member 303 are symmetrically arranged, and the contact points of the first telescopic drive member 301, the second telescopic drive member 302 and the third telescopic drive member 303 on the base 200 can form an isosceles triangle.

[0046] Taking the first telescopic driving member 301 as an example, the specific structure of the telescopic driving member is as follows: Figure 4 As shown, the structure of the second telescopic driving member 302 and the structure of the third telescopic driving member 303 are consistent with the structure of the first telescopic driving member 301 .

[0047] The first telescopic driving member 301 includes a first connecting member 301a, a driving body 301b and a second connecting member 301c, which are respectively arranged at two ends of the driving body 301b and are respectively used to connect with the base 200 and the box 100. The driving body 301b can be a driving member such as an electric cylinder or a pneumatic cylinder.

[0048] In one embodiment, a groove is provided on the first connecting member 301a, and a first through hole and a second through hole are respectively provided on the two side walls of the groove, and the two through holes are symmetrical to each other; a connecting head matching the first connecting member 301a is provided on the base 200, and the connecting head is a convex block with a hole in the middle; a pin is used to pass through the first through hole, the connecting head on the base 200 and the second through hole in sequence to realize the connection between the first connecting member 301a and the base 200.

[0049] In another embodiment, a groove is provided on the first connecting member 301a, and a clamping column is provided between the two side walls of the groove, and the clamping column is a cylinder; a connecting head matching the first connecting member 301a is provided on the base 200, and the connecting head is an elastic protrusion with an arc-shaped groove, and the opening diameter of the groove is smaller than the diameter of the clamping column; the clamping column is pressed into the arc-shaped groove with a little force to realize the connection between the first connecting member 301a and the base 200.

[0050] The structure of the second connecting member 301c is consistent with that of the first connecting member 301a, and the connection method between the second connecting member 301c and the box body 100 is also consistent with the connection method between the first connecting member 301a and the base 200, which will not be repeated here.

[0051] In one embodiment, Figure 5 As shown, the support arm driving assembly 220 includes a rotating platform 221 , a rotating shaft 222 and a rotating shaft driving member 223 .

[0052] Among them, the shaft driving member 223 is fixed on the base 200 and connected to the shaft 222, and is used to drive the shaft 222 to rotate; the shaft 222 is connected to the rotating table 221, and the rotating table 221 is fixed on the bottom surface of one end of the shaft 222, so that the rotating table 221 and the shaft 222 remain relatively stationary, that is, when the shaft 222 rotates, the rotating table 221 can rotate accordingly; one end of the support arm 210 is fixed to the rotating table 221 by a fastener, and when the rotating table 221 rotates, the support arm 210 swings in the pitch axis direction, and its swinging angle is consistent with the rotation angle of the rotating table 221.

[0053] The shaft driving member 223 may also include a shell, in which the rotating table 221, the rotating shaft 222 and the rotating shaft driving member 223 are all arranged. The bottom of the shell is fixedly connected to the base 200, and a fixing hole for connecting the rotating table 221 and the support arm 210 is opened on the side wall of the shell.

[0054] In this embodiment, there are two support arms 210, which are respectively arranged on both sides of the rotating shaft driving member 223, and there are also two rotating platforms 221 and rotating shafts 222, which are respectively matched and connected with the two support arms 210. Among them, the rotating shaft driving member 223 can be one, which is a double-output shaft type motor, and the two ends are respectively connected to the two rotating shafts 222; or there can be two, which are respectively connected to the two rotating shafts 222.

[0055] In one embodiment, Figure 6 As shown, a mounting frame 230 for mounting the communication device is provided on the base 200, and the mounting frame 230 is connected to the support arm 210. Specifically, a connecting block 231 is provided on the mounting frame 230; a convex piece is provided on the connecting end of the support arm 210 and the support arm driving assembly 220, and a connecting hole is provided on the convex piece; the connecting block 231 is connected to the convex piece of the support arm 210 by screws. When the support arm 210 swings upward, the convex piece rotates and the mounting frame 230 rises; when the support arm 210 swings downward, the convex piece rotates and the mounting frame 230 falls.

[0056] Among them, a positioning rod 211 is connected between the support arm 210 and the mounting frame 201, and the positioning rod 211 is a step design. In this embodiment, the positioning rod 211 is divided into two sections, the first section and the second section are cocentric, and the diameter of the first section is larger than the diameter of the second section; a positioning slot 232 is provided on one side of the mounting frame 230, and a third through hole is provided in the positioning slot 232, and the diameter of the third through hole is smaller than the diameter of the first section and larger than the diameter of the second section; one end of the first section of the positioning rod 211 is connected to the support arm 210, and the second section of the positioning rod 211 passes through the positioning slot 232.

[0057] The satellite communication box in this embodiment can prevent the support arm 210 from swinging downward at too large an angle, thereby causing the antenna assembly 400 to collide with the communication equipment on the mounting bracket 230 .

[0058] In one embodiment, a controller and a control area 240 are provided on the base 200. The control area 240 includes control keys and a signal interface. The control keys and the signal interface are both connected to the controller. The controller is also respectively connected to the lifting assembly 300, the retracting and extending drive component 403 and the support arm drive assembly 220.

[0059] Among them, the control keys are used to control the movement of the lifting assembly 300, the retractable drive component 403 and the support arm drive assembly 220; the signal interface is used to realize the connection between the communication equipment and the antenna assembly 400 and the signal transceiver source; the controller is used to process the input data and output the command or data to the execution entity or receiving source.

[0060] like Figure 7 As shown, the control area 240 is arranged below the support arm driving assembly 220, and the controller can be arranged in the base 200. The control keys include a descending button 241, a retracting handle 242, and a swing handle 243; the signal interface includes a signal receiving source interface 244, a signal transmitting source interface 245, and a debugging interface 246.

[0061] The descending button 241 is used to control the retraction of the telescopic driving member in the lifting assembly 300 to lower the base 200; the retracting handle 242 is used to control the extension or retraction of the transceiver driving member 403, thereby controlling the state switching of the antenna assembly; the swing handle 243 is used to control the rotation angle of the support arm driving assembly 220, thereby controlling the orientation of the antenna assembly 400; the signal receiving source interface 244 is used to realize the connection between the communication device and the antenna assembly 400 and the signal receiving source; the signal transmitting source interface 245 is used to realize the connection between the communication device and the antenna assembly 400 and the signal transmitting source; the debugging interface 246 is used to debug the antenna assembly 400 and the communication device.

[0062] In one embodiment, Figure 8As shown, the box 100 includes a box body 110 and a box cover 120, and the box cover 120 is connected or hinged to the box body 100; the height of the inner wall of the box cover 110 is greater than zero. The deep-type box cover 110 can accommodate the antenna assembly 400 in a folded state, reduce the lifting height of the base 200, and save space.

[0063] The box body 110 is provided with a power interface 111 and a switch button 112 , and both the power interface 111 and the switch button 112 are connected to the controller.

[0064] The power interface 111 is used to connect an external power source to provide power to the equipment in the box 100; the switch button 112 is used to control the on and off of the power source. After opening the box cover 120, the user can connect the external power source through the power interface 111 and press the switch button 112 to turn on the power. The external power source supplies power to the controller and other components. At this time, the lifting component 300 starts to work, and the telescopic drive member extends to raise the base 200; after the base 200 is raised, the user can connect the signal interface and control the state and direction of the antenna component 400 through the control key; after use, the control key can continue to control the antenna component 400 to fold and move downward. After the antenna component 400 is restored, the base 200 is reset and the box cover 120 is closed.

[0065] In the satellite communication box, the antenna can be switched between the unfolded and folded states through the retractable drive member 403, and the movement in the pitch axis direction can be achieved through the support arm 210 and the support arm drive assembly 220, without the need to manually assemble the antenna; at the same time, the base 200 can be automatically raised or lowered through the lifting assembly 300, without the need to manually take out the communication equipment in the box 100. The satellite communication box shortens the time for setting up, opening and retracting the communication equipment, and the folding design makes it smaller in size and more convenient to carry and use.
