An antenna deployment locking mechanism

Abstract

The application discloses an antenna unfolding locking mechanism and relates to the technical field of antenna unfolding. The antenna unfolding locking mechanism comprises an electric cylinder, a mounting plate and a locking device for connecting an antenna panel. The output end of the electric cylinder is fixedly provided with an extension rod, and the surface of the extension rod is sleeved with a connecting seat. The antenna unfolding locking mechanism hooks the panel with the hook plate and the lock catch, and does not need to be adsorbed by the magnetic force of an electromagnetic device, so that the panel is fastened more stably. The hook plate assembly pushes the moving block to move. When the moving block moves, the arc-shaped air bag is extruded, so that the gas in the arc-shaped air bag enters the inside of the hollow frame through the communicating pipe. When the air pressure in the inside of the hollow frame increases, the sealing plate and the Z-shaped plate are pushed to move. When the Z-shaped plate moves to the outside of the lock catch, the hook plate assembly can be limited at the curved position of the lock catch, so that the lock catch is prevented from being separated from the hook plate assembly.

Description

Technical Field

[0001] This invention relates to the field of antenna deployment technology, specifically to an antenna deployment locking mechanism. Background Technology

[0002] Antennas are common and important components used for signal transmission. During use, antennas generally need to be used in combination in two states: extended and closed.

[0003] The commonly used single-fold antenna is locked in the unfolded state by the attraction and force of an electromagnet. However, the attraction force of the electromagnet cannot be guaranteed, and the electromagnet requires uninterrupted power to maintain its magnetic force, which limits the use of single-fold antennas. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides an antenna deployment and locking mechanism, which solves the problems mentioned in the background section.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, the present invention provides the following technical solution: an antenna deployment and locking mechanism, an electric cylinder and a mounting plate; a locking device for connecting the antenna panel, comprising a telescopic rod, a hook plate assembly, a connecting seat and a latch, wherein the telescopic rod is fixedly installed at the output end of the electric cylinder, the connecting seat is sleeved on the surface of the telescopic rod, the hook plate assembly is rotatably installed at the free end of the telescopic rod, and the latch is installed on the top of the mounting plate;

[0008] The limiting device includes a moving block, an arc-shaped airbag, a hollow frame, a Z-shaped plate, and a sealing plate. The moving block is slidably sleeved on the left side of the latch. The arc-shaped airbag and the hollow frame are fixedly installed on the inner wall of the latch. The sealing plate is slidably installed on the inner wall of the hollow frame. The Z-shaped plate is fixedly installed on the left side of the sealing plate. The arc-shaped airbag is connected to the interior of the hollow frame through a connecting pipe. An electrically controlled electric cylinder drives the telescopic rod and the hook plate assembly to move away from the latch, causing the hook plate assembly to pull the latch and the mounting plate to move, thereby fitting the two panels together without the need for magnetic attraction by an electromagnetic device, making the panels more stable. The gas inside the arc-shaped airbag enters the interior of the hollow frame through the connecting pipe. The increased air pressure inside the hollow frame pushes the sealing plate and the Z-shaped plate to move inward into the hollow frame. When the Z-shaped plate moves outward from the latch, it can limit the hook plate assembly to the bent position of the latch, preventing the latch from detaching from the hook plate assembly.

[0009] Preferably, a spring is provided between the sealing plate and the inner wall of the hollow frame, and a return spring is provided between the moving block and the latch, so that the sealing plate can be reset by the elastic force of the spring.

[0010] Preferably, the right side of the connecting seat is provided with a groove, and a disengagement device is provided inside the groove. The disengagement device includes a stop block, which is slidably installed on the inner wall of the groove. An inclined block is slidably installed at the bottom of the groove. An electromagnet is fixedly installed on the inner wall of the groove. The electromagnet is electrically connected to the electric cylinder. A permanent magnet is slidably installed on the inner wall of the groove.

[0011] Preferably, a first spring is provided between the stop block and the groove, a second spring is provided between the tilting block and the groove, the end of the permanent magnet near the electromagnet has the same magnetic pole as the electromagnet, and a third spring is provided between the permanent magnet and the groove. When the electromagnet exerts magnetic force, the like poles repel each other, causing the electromagnet to push the permanent magnet downward. When the permanent magnet moves upward, it releases the limit on the tilting block. Under the elastic force of the second spring, the tilting block will be pushed to move outward of the groove. When the tilting block moves, it will no longer be able to support the stop block. Under the elastic force of the first spring, it will drive the stop block downward. The downward movement of the stop block will release the limit on the latch, preventing the latch and hook plate assembly from being unable to disengage after the electric cylinder is damaged.

[0012] Preferably, a pushing device is provided inside the groove. The pushing device includes a movable metal that is slidably installed inside the groove. A rotating plate is rotatably installed on the inner wall of the groove. A force-receiving airbag is fixedly installed on the inner wall of the groove. A fixing plate is fixedly installed on the inner wall of the groove. A pushing airbag is fixedly installed on the surface of the fixing plate. A contact plate is fixedly installed on the surface of the permanent magnet. The force-receiving airbag and the connecting pipe are connected to the interior of the pushing airbag.

[0013] Preferably, a rotating wheel is rotatably installed inside the groove, and a No. 4 spring is provided between the movable metal and the groove. The rotating wheel can reduce the friction of the permanent magnet movement. The movable metal will push the rotating plate to rotate. When the rotating plate rotates, it will squeeze the force-bearing airbag, causing the gas inside the force-bearing airbag to enter the interior of the pushing airbag through the connecting pipe. The increase of gas inside the pushing airbag will cause it to expand. By pushing the airbag to expand, it will push the contact plate to move upward, preventing the permanent magnet from getting stuck inside the groove and being unable to move upward, thus releasing the limitation on the tilting block.

[0014] Preferably, the surface of the latch is provided with a lubrication device, which includes a storage frame, an adsorption plate fixedly installed on the top of the storage frame, and a sponge plate fixedly installed on the top of the latch. The top of the adsorption plate is fixed to the sponge plate. The adsorption plate can adsorb the lubricating oil inside the storage frame, so that the lubricating oil inside the storage frame will be adsorbed into the interior of the sponge plate through the adsorption plate. The sponge plate can play a lubricating role between the latch and the hook plate assembly.

[0015] Preferably, a pressing plate is slidably sleeved on the top of the latch, a notch block is fixedly installed on the surface of the pressing plate, an L-shaped plate is fixedly installed on the top of the Z-shaped plate, a triangular groove is formed on the side of the notch block near the L-shaped plate, the pressing plate contacts the sponge plate, and when the L-shaped plate moves, it moves into the interior of the triangular groove. When the L-shaped plate slides inside the triangular groove, it pushes the notch block and the pressing plate downward. When the pressing plate moves downward, it squeezes the sponge plate, which can improve the flow effect of the sponge plate in the latch.

[0016] (III) Beneficial Effects

[0017] This invention provides an antenna deployment locking mechanism. It has the following advantages:

[0018] (1) When the side panel is unfolded, the latch is in place, the electric cylinder drives the telescopic rod to retract, and the hook plate hooks the panel onto the latch. It does not require magnetic attraction through an electromagnetic device, making the panel more stable. When the latch and the moving block are squeezed by the hook plate assembly, the hook plate assembly will push the moving block to move. When the moving block moves, it will squeeze the arc-shaped airbag, so that the gas inside the arc-shaped airbag enters the interior of the hollow frame through the connecting pipe. When the air pressure inside the hollow frame increases, it will push the sealing plate and the Z-shaped plate to move. When the Z-shaped plate moves to the outside of the latch, it can restrict the hook plate assembly to the bent position of the latch, preventing the latch from detaching from the hook plate assembly.

[0019] (2) When the electric cylinder is damaged and cannot drive the telescopic rod, the power supply of the electric cylinder and the electromagnet is disconnected, so that the permanent magnet will move upward to release the limit on the tilt block, so that the tilt block will move to the outside of the groove, so that the stop block can move downward to release the limit on the latch, so that the latch can move in the direction of the electric cylinder, so that the latch can be disengaged from the hook plate assembly, thus preventing the latch from being unable to disengage from the hook plate assembly after the electric cylinder is damaged.

[0020] (3) When the power supply to the electromagnet is disconnected, the moving metal will move away from the electromagnet, causing the moving metal to push the rotating plate to rotate and squeeze the pressure airbag. This causes the gas inside the pressure airbag to enter the interior of the pushing airbag through the connecting pipe. The expansion of the pushing airbag will push the contact plate to move upward, and the upward movement of the contact plate will push the permanent magnet to move upward, thus preventing the permanent magnet from getting stuck inside the groove and being unable to move upward, thereby releasing the limit on the tilting block.

[0021] (4) The antenna unfolding locking mechanism can absorb the lubricating oil inside the storage frame through the adsorption plate. The adsorption plate will absorb the lubricating oil inside the storage frame and enter the interior of the sponge plate, so that the sponge plate can lubricate the buckle and hook plate assembly. When the Z-shaped plate moves into the interior of the hollow frame, the L-shaped plate will move into the triangular groove of the notch plate, so that the L-shaped plate will push the notch plate and the pressing plate downward. When the pressing plate moves downward, it will squeeze the sponge plate, thereby improving the effect of the lubricating oil in the sponge plate flowing on the buckle surface.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see Figure 1-7 The present invention provides a technical solution: an antenna deployment and locking mechanism, an electric cylinder 1 and a mounting plate 5; a locking device for connecting the antenna panel, including a telescopic rod 2, a hook plate assembly 3, a connecting seat 4 and a latch 6, wherein the telescopic rod 2 is fixedly installed at the output end of the electric cylinder 1, the connecting seat 4 is sleeved on the surface of the telescopic rod 2, the hook plate assembly 3 is rotatably installed at the free end of the telescopic rod 2, and the latch 6 is installed on the top of the mounting plate 5.

[0032] The limiting device includes a movable block 71, an arc-shaped airbag 72, a hollow frame 73, a Z-shaped plate 75, and a sealing plate 74. The movable block 71 is slidably sleeved on the left side of the latch 6. The arc-shaped airbag 72 and the hollow frame 73 are fixedly installed on the inner wall of the latch 6. The sealing plate 74 is slidably installed on the inner wall of the hollow frame 73. The Z-shaped plate 75 is fixedly installed on the left side of the sealing plate 74. The arc-shaped airbag 72 is connected to the interior of the hollow frame 73 through a connecting pipe 76. The electric cylinder 1 and the connecting seat 4 are installed on another panel. When the electric cylinder 1 is operated, it pushes the telescopic rod 2 and the hook plate assembly 3 to move towards the mounting plate 5 and the latch 6, so that the hook plate assembly 3 moves to the arc-shaped position of the latch 6. Then, the electric cylinder 1 is controlled to drive the telescopic rod 2 and the hook plate assembly 3 to move away from the latch 6. The hook plate assembly 3 pulls the latch 6 and the mounting plate 5 to move, thus fitting the two panels together without the need for magnetic attraction from an electromagnetic device, making the panels more securely fastened. When the hook plate assembly 3 pulls the latch 6, it pushes the moving block 71 to move inward into the latch 6. As the moving block 71 moves, it compresses the arc-shaped airbag 72, causing the gas inside the arc-shaped airbag 72 to enter the hollow frame 73 through the connecting pipe 76. The increased air pressure inside the hollow frame 73 pushes the sealing plate 74 and the Z-shaped plate 75 to move inward into the hollow frame 73. When the Z-shaped plate 75 moves outward from the latch 6, it can restrict the hook plate assembly 3 to the bent position of the latch 6, preventing the latch 6 from detaching from the hook plate assembly 3.

[0033] A spring is provided between the sealing plate 74 and the inner wall of the hollow frame 73, and a reset spring is provided between the moving block 71 and the latch 6. The spring force can drive the sealing plate 74 to reset.

[0034] A groove is provided on the right side of the connecting seat 4. A disengagement device is provided inside the groove. The disengagement device includes a stop block 81, which is slidably installed on the inner wall of the groove. An inclined block 82 is slidably installed at the bottom of the groove. An electromagnet 83 is fixedly installed on the inner wall of the groove. The electromagnet 83 is electrically connected to the electric cylinder 1. A permanent magnet 84 is slidably installed on the inner wall of the groove.

[0035] A first spring is provided between the stop block 81 and the groove, and a second spring is provided between the tilting block 82 and the groove. The end of the permanent magnet 84 near the electromagnet 83 has the same magnetic pole as the electromagnet 83. A third spring is provided between the permanent magnet 84 and the groove. When the electromagnet 83 exerts magnetic force, the repulsion between like poles causes the electromagnet 83 to push the permanent magnet 84 downward, disconnecting the power supply to the electric cylinder 1. At the same time, the power supply to the electromagnet 83 is also disconnected. When the power supply to the electromagnet 83 is disconnected, the electromagnet 83 loses its magnetic force, preventing it from pushing the permanent magnet 84 downward. When magnet 84 moves downward, the elastic force of the third spring will push permanent magnet 84 upward. When permanent magnet 84 moves upward, it will release the limit on tilt block 82. Under the elastic force of the second spring, tilt block 82 will be pushed to move outward of the groove. When tilt block 82 moves, it will no longer be able to support stop block 81. Under the elastic force of the first spring, stop block 81 will be driven to move downward. When stop block 81 moves downward, it will release the limit on latch 6, so that latch 6 and hook plate assembly 3 cannot be separated after electric cylinder 1 is damaged.

[0036] The groove is equipped with a pushing device, which includes a movable metal 85. The movable metal 85 is slidably installed inside the groove and is made of a material such as iron that can be attracted by a magnet. A rotating plate 86 is rotatably installed on the inner wall of the groove. A force-receiving airbag 87 is fixedly installed on the inner wall of the groove. A fixed plate 88 is fixedly installed on the inner wall of the groove. A pushing airbag 89 is fixedly installed on the surface of the fixed plate 88. A contact plate 810 is fixedly installed on the surface of the permanent magnet 84. The force-receiving airbag 87 and the connecting pipe 811 are connected to the interior of the pushing airbag 89.

[0037] A rotating wheel 812 is installed inside the groove. A fourth spring is provided between the movable metal 85 and the groove. The rotating wheel 812 can reduce the friction of the permanent magnet 84. When the electromagnet 83 loses its magnetism, it will not be able to attract the movable metal 85. Under the elastic force of the fourth spring, the movable metal 85 will be pushed to move away from the electromagnet 83. The movable metal 85 will push the rotating plate 86 to rotate. When the rotating plate 86 rotates, it will squeeze the force-bearing airbag 87, so that the gas inside the force-bearing airbag 87 enters the interior of the pushing airbag 89 through the connecting pipe 811. The increase of gas inside the pushing airbag 89 will cause it to expand. The expansion of the pushing airbag 89 will push the contact plate 810 to move upward, preventing the permanent magnet 84 from getting stuck inside the groove and being unable to move upward, thus releasing the limit on the tilting block 82.

[0038] The surface of the latch 6 is provided with a lubrication device, which includes a storage frame 91. An adsorption plate 92 is fixedly installed on the top of the storage frame 91, and a sponge plate 93 is fixedly installed on the top of the latch 6. The top of the adsorption plate 92 is fixed to the sponge plate 93. The adsorption plate 92 can adsorb the lubricating oil inside the storage frame 91, so that the lubricating oil inside the storage frame 91 will be adsorbed into the interior of the sponge plate 93 through the adsorption plate 92. The sponge plate 93 can provide a lubricating effect between the latch 6 and the hook plate assembly 3.

[0039] A pressing plate 94 is slidably sleeved on the top of the latch 6. A notch block 95 is fixedly installed on the surface of the pressing plate 94. An L-shaped plate 96 is fixedly installed on the top of the Z-shaped plate 75. A triangular groove is opened on the side of the notch block 95 near the L-shaped plate 96. The pressing plate 94 contacts the sponge plate 93. When the L-shaped plate 96 moves, it will move into the triangular groove. When the L-shaped plate 96 slides inside the triangular groove, it will push the notch block 95 and the pressing plate 94 downward. When the pressing plate 94 moves downward, it will squeeze the sponge plate 93, which can improve the flow effect of the sponge plate 93 in the latch 6.

[0040] When connecting the antenna panel during operation (or use), the mounting plate 5 is bolted onto the panel, and then the electric cylinder 1 and connecting seat 4 are mounted on another panel. The operation of the electric cylinder 1 pushes the telescopic rod 2 and hook plate assembly 3 towards the mounting plate 5 and locking buckle 6, causing the hook plate assembly 3 to move to the arc-shaped position of the locking buckle 6. Then, the electric cylinder 1 is controlled to move the telescopic rod 2 and hook plate assembly 3 away from the locking buckle 6, causing the hook plate assembly 3 to pull the locking buckle 6 and mounting plate 5 forward. The movement allows the two panels to be joined together. When the hook plate assembly 3 pulls the latch 6 to move, the hook plate assembly 3 will push the moving block 71 to move inward into the latch 6. When the moving block 71 moves, it will compress the arc-shaped airbag 72, causing the gas inside the arc-shaped airbag 72 to enter the interior of the hollow frame 73 through the connecting pipe 76. The increased air pressure inside the hollow frame 73 will push the sealing plate 74 and the Z-shaped plate 75 to move inward into the hollow frame 73, causing the Z-shaped plate 75 to move outward from the latch 6.

[0041] The adsorption plate 92 can adsorb the lubricating oil inside the storage frame 91, so that the lubricating oil inside the storage frame 91 will be adsorbed into the interior of the sponge plate 93 through the adsorption plate 92.

[0042] When the electric cylinder 1 is damaged and cannot move the telescopic rod 2, and the panel needs to be disassembled, the power supply to the electric cylinder 1 is disconnected, and the power supply to the electromagnet 83 is also disconnected. When the power supply to the electromagnet 83 is disconnected, the electromagnet 83 loses its magnetic force, so the electromagnet 83 cannot push the permanent magnet 84 downward. Under the elastic force of the third spring, the permanent magnet 84 will be pushed upward. When the permanent magnet 84 moves upward, it will release the limit on the tilt block 82. Under the elastic force of the second spring, the tilt block 82 will be pushed to move outward of the groove. When the tilt block 82 moves, it will not be able to support the stop block 81. Under the elastic force of the first spring, the stop block 81 will be driven downward. The downward movement of the stop block 81 will release the limit on the latch 6, so that the latch 6 can move in the direction of the electric cylinder 1, so that the latch 6 can be disengaged from the hook plate assembly 3. When the hook plate assembly 3 is damaged, the latch 6 can also be disengaged from the hook plate assembly 3.

[0043] When electromagnet 83 loses its magnetism, it will be unable to attract the movable metal 85. Under the elastic force of the fourth spring, the movable metal 85 will be pushed to move away from the electromagnet 83. The movable metal 85 will push the rotating plate 86 to rotate. When the rotating plate 86 rotates, it will squeeze the force-bearing airbag 87, causing the gas inside the force-bearing airbag 87 to enter the pushing airbag 89 through the connecting pipe 811. The increase in gas inside the pushing airbag 89 will cause it to expand. The expansion of the pushing airbag 89 will push the contact plate 810 to move upward. The upward movement of the contact plate 810 will drive the permanent magnet 84 to move upward, preventing the permanent magnet 84 from getting stuck inside the groove.

[0044] When the latch 6 disengages from the hook plate assembly 3, the spring force will cause the sealing plate 74 and the Z-shaped plate 75 to move into the hollow frame 73. When the Z-shaped plate 75 moves, it will cause the L-shaped plate 96 to move. When the L-shaped plate 96 moves, it will move into the triangular groove. When the L-shaped plate 96 slides in the triangular groove, it will push the notch block 95 and the pressing plate 94 downward. When the pressing plate 94 moves downward, it will squeeze the sponge plate 93, causing the lubricating oil inside the sponge plate 93 to be squeezed out and flow on the latch 6.

[0045] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
