Description

Technical Field

[0001] This invention belongs to the field of underwater vehicle component drive technology, and particularly relates to a device for achieving composite drive of antenna and antenna cover using a single electric mechanism. Background Technology

[0002] Some submarines or underwater vehicles need to surface to about 1 meter below the water's surface to communicate with the outside world, and then extend their communication antennas above the water to transmit and receive data. These communication antennas are usually folded inside the vehicle's fuselage and shielded by a hatch, which also serves as a rectifier.

[0003] Typically, the extension and retraction control of the communication antenna is independent of the opening and closing control of the antenna cover; that is, the antenna and the antenna cover are driven by different electric mechanisms. This method currently has the following problems:

[0004] 1. The electric mechanisms applicable to underwater vehicles are all customized products, with high requirements for waterproof, corrosion-resistant, and low-temperature resistant environments. Increasing the number of electric mechanisms will directly lead to an increase in cost and structural weight, and at the same time, it also puts forward higher requirements for overall layout and installation space.

[0005] 2. The operation of the antenna and antenna cover requires precise timing control, which increases the complexity of the controller software and control circuit.

[0006] 3. Multiple electric mechanisms introduce multiple points of failure, and any single failure could lead to the failure of the antenna's retraction and extension functions. Summary of the Invention

[0007] Purpose of the invention

[0008] To solve the above-mentioned technical problems, the present invention provides a device for achieving composite driving of antenna and antenna cover using a single electric mechanism, which realizes synchronous control of the extension / retraction of underwater vehicle communication antenna and the opening / closing of antenna cover using a single electric mechanism.

[0009] Invention Technology Solutions

[0010] A device for achieving combined driving of an antenna and an antenna cover using a single electric mechanism includes an antenna cover, an antenna cover drive connector fixedly connected to the lower surface of the antenna cover, an antenna cover drive connector slidably connected to an antenna cover lifting member, an antenna fixed to one end of a support rod, the other end of the support rod hinged to a support rod hinge support, one end of a rocker arm that can slide along the support rod, the other end of the rocker arm that is rotatably connected to a rocker arm support column, and the rocker arm support column and the antenna cover lifting member fixed to the telescopic rod of the electric mechanism.

[0011] Preferably, the lid lifting component has a bent structure.

[0012] Preferably, the lid lifting member has a guide groove, and the pin connected to the lid driving connector can slide along the guide groove on the lid lifting member.

[0013] Preferably, one side of the hatch is hinged with multiple hatch hinge supports, which are fixed to the aircraft body structure.

[0014] Preferably, the rocker arm is connected to the slider, and the slider can slide along the support rod.

[0015] Preferably, a groove is provided at one end of the strut near the strut hinge support, and the slider can slide along the groove on the strut.

[0016] Preferably, in the initial state, the cover is closed and the antenna is retracted and shielded under the cover.

[0017] Preferably, the electric mechanism is fixedly connected to the push rod mounting lugs via two push rod mounting plates fixed thereon, and the push rod mounting plates are fixed to the structural components of the aircraft body.

[0018] The advantages of this invention are: While meeting functional requirements, the device reduces system complexity, lightens structural weight, and saves on unit development costs. During device movement, only necessary extension and retraction control of the electric mechanism is required, simplifying the control circuit and operating procedures. This avoids problems associated with the timing control logic settings, position feedback status acquisition, and telescopic rod stroke control required for coordinated control of multiple electric mechanisms. Furthermore, using a single electric mechanism as the drive device effectively reduces potential failure points and prevents antenna malfunction due to different fault points.

[0022] The present invention is achieved through the following technical solution.

[0023] like Figure 1 , Figure 2As shown, a device for combined driving of an antenna and an antenna cover using a single electric mechanism includes an antenna cover 1, an antenna cover hinge support 2, an antenna cover drive connector 3, an antenna 4, a support rod 5, a support rod hinge support 6, a slider 7, a rocker arm 8, an electric mechanism 9, an antenna cover lifting component 10, a rocker arm support column 11, a push rod mounting lug 12, and a push rod fixing seat 13.

[0024] The cover 1 is a thin, long plate, and one side of it is hinged to multiple cover hinge supports 2. The cover hinge supports 2 are fixed to the aircraft body structure to ensure that the cover 1 can rotate stably and reliably around the cover hinge supports 2.

[0025] The cap drive connector 3 is fixed to the lower surface of the cap 1 and connected to the cap lifting member 10 by a pin, ensuring that the cap drive connector 3 can slide along the guide groove on the cap lifting member 10 when the cap lifting member 10 moves.

[0026] Antenna 4 is fixed to support rod 5 by bolts. The lower half of support rod 5 is provided with a sliding groove, and the end is fixed to support rod hinge support 6 by a pin, so that it can rotate around support rod hinge support 6.

[0027] The slider 7 connects the support rod 5 and the rocker arm 8. The lower end of the rocker arm 8 is hinged to the rocker arm support column 11, which is fixed to the side wall of the telescopic rod of the electric mechanism 9 by screwing. When the rocker arm support column 11 moves axially with the extension rod of the electric mechanism 9, the lower end of the rocker arm 8 rotates around the support column, and the upper end drives the slider 7 to move along the slide groove of the support rod 5, thereby driving the support rod 5 to rotate around the support rod hinge support 6.

[0028] The electric mechanism 9 is fixedly connected to the push rod mounting lugs 12 and the push rod fixing seat 13 via two push rod mounting lugs 12 fixed thereon. The push rod fixing seat 13 is fixed to the machine body structure to ensure that only the telescopic rod part of the electric mechanism 9 can perform axial telescopic movement when energized.

[0029] The lid lifting component 10 is an irregularly shaped part with a bent angle, and a guide groove is provided on its symmetrical line for cooperating with the lid drive connector 3 to convert the telescopic motion output by the electric mechanism 9 into the rotational motion of the lid 1. The lid lifting component 10 is fixed to the end of the telescopic rod of the electric mechanism 9 by screwing, and moves telescopically with the telescopic rod as a whole.

[0030] The working mode of this invention embodiment is as follows: In the initial state, the telescopic rod of the electric mechanism 9 is in the retracted state, the cover 1 is in the closed state, and the antenna 4 is in the retracted state.

[0031] When antenna 4 needs to be extended, the telescopic rod of the electric mechanism 9 is extended via an external control circuit, causing the cover lifting member 10 and the rocker arm support column 11 to move outward. The pin on the cover drive connector 3 slides along the guide groove on the lifting member. When it moves in the bending section groove, the cover 1 flips around the cover hinge support 2, thus completing the opening action of the cover 1; when it moves in the vertical section groove, the cover 1 remains at the maximum flipping angle. Simultaneously, the lower end of the rocker arm 8 rotates around the support column, and the upper end drives the slider 7 to move along the groove of the support rod 5, thereby driving the support rod 5 to rotate around the support rod hinge support 6, thus completing the extension action of antenna 4.

[0032] When antenna 4 needs to be retracted, the telescopic rod of the electric mechanism 9 is retracted via an external control circuit, causing the cover lifting component 10 and the rocker arm support column 11 to move inward. The pin on the cover drive connector 3 slides along the guide groove on the lifting component. When it moves in the vertical section of the slide groove, the cover 1 remains at its maximum flipping angle. When it moves in the bending section of the slide groove, the cover 1 flips around the cover hinge support 2, thus completing the closing action of the cover 1. Simultaneously, the lower end of the rocker arm 8 rotates in the opposite direction around the support column, and the upper end drives the slider 7 to move in the opposite direction along the slide groove of the support rod 5, thereby driving the support rod 5 to rotate in the opposite direction around the support rod hinge support 6, thus completing the retraction action of antenna 4.

[0033] The scope of protection of this invention is not limited to the embodiments described above. Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its scope. If such modifications and variations fall within the scope of the claims of this invention and their equivalents, then the intent of this invention also includes these modifications and variations.
