Description

Technical Field

[0001] This invention relates to the technical field of millimeter-wave receivers, and more particularly to a millimeter-wave receiver. Background Technology

[0002] Electromagnetic waves with wavelengths of 1-10 millimeters are called millimeter waves. Millimeter waves have numerous applications in fields such as communications, radar, remote sensing, and radio astronomy. A millimeter-wave receiver is an essential component of millimeter-wave radar, amplifying, transforming, and processing echo signals. To receive signals in real time, millimeter-wave receivers are typically installed in an open environment, facing the direction of the signal. Some millimeter-wave receivers also feature a rotating platform to receive signals from multiple directions.

[0003] However, in some environments with obstacles, millimeter-wave receivers can only rotate back and forth within a certain angle and cannot perform a complete circular rotation. Therefore, ordinary millimeter-wave receivers that can rotate in a circular motion are difficult to adapt to such special environments. Summary of the Invention

[0004] To facilitate the operation of millimeter-wave receivers in environments with obstacles, this application provides a millimeter-wave receiver.

[0005] This application provides a millimeter-wave receiver, which adopts the following technical solution:

[0006] A millimeter-wave receiver includes a receiving radar, a base, a reciprocating rotary table, and a reciprocating drive assembly. The reciprocating rotary table is rotatably connected to the base, and the receiving radar is mounted on the reciprocating rotary table. The reciprocating drive assembly includes a linear reciprocating rod, a drive block, a fixed frame, and a reciprocating drive component. The fixed frame and the reciprocating drive component are both disposed on the base. The linear reciprocating rod is slidably connected to the fixed frame. One end of the linear reciprocating rod is connected to the reciprocating drive component, and the other end of the linear reciprocating rod is fixedly connected to the drive block. The reciprocating rotary table is provided with a reciprocating straight groove, and the drive block is inserted into the reciprocating straight groove.

[0007] By adopting the above technical solution, the fixed frame is used to support the linear reciprocating rod and limit the linear reciprocating rod to move along a straight line. The reciprocating drive drives the linear reciprocating rod to reciprocate along the same straight line. The drive block moves synchronously with the linear reciprocating rod. Therefore, the drive block can move in the reciprocating straight groove and push the reciprocating rotary table to rotate. The reciprocating rotary table and the receiving radar can reciprocate within a set angle, which facilitates the millimeter wave receiver to work in an environment with obstacles.

[0008] In one specific implementation, the reciprocating drive includes a drive rod, a rocker arm, and a power component. The rocker arm is rotatably connected to a fixed frame, one end of the rocker arm is connected to the power component, the other end of the rocker arm is rotatably connected to the drive rod, and the end of the drive rod away from the rocker arm is rotatably connected to a linear reciprocating rod.

[0009] By adopting the above technical solution, the power component drives the rocker arm to reciprocate within a specified angle, and the drive rod moves synchronously with the rocker arm. When the rocker arm rotates away from the linear reciprocating rod, the drive rod can pull the linear reciprocating rod to slide away from the reciprocating rotary table. When the rocker arm rotates towards the linear reciprocating rod, the drive rod can push the linear reciprocating rod to slide towards the reciprocating rotary table. Therefore, the effect of driving the linear reciprocating rod to reciprocate along a straight line can be achieved.

[0010] In one specific implementation, the power component includes a cam, a power motor, and a transmission block. The power motor is fixedly connected to a fixed frame, the cam is fixedly connected to the motor shaft of the power motor, the cam is provided with a transmission ring groove, and the transmission block is fixedly connected to the end of the rocker arm away from the drive rod, and the transmission block is inserted into the transmission ring groove.

[0011] By adopting the above technical solution, the power motor drives the cam to rotate, and the cam applies a thrust to the transmission block. Under the action of the thrust, the transmission block moves along the transmission ring groove. Therefore, the transmission block moves back and forth under the push of the cam. Since the rocker arm is rotatably connected to the fixed frame, the transmission block drives the rocker arm to rotate back and forth around the rotation connection point as the center, thereby achieving the effect of driving the linear reciprocating rod to move back and forth along a straight line.

[0012] In one specific implementation, the fixing frame includes a fixing cylinder, a bracket, a connecting block, and a lever. The fixing cylinder and the bracket are both fixedly connected to the base. The linear reciprocating rod passes through the fixing cylinder. The connecting block is connected to the bracket. The lever is rotatably connected to the connecting block. The rocker arm has a through hole, and the lever is inserted into the through hole.

[0013] By adopting the above technical solution, the fixed cylinder can restrict the linear reciprocating rod from moving in a straight line, and the connecting block and lever can rotatably connect the rocker arm to the bracket, so that the rocker arm can rotate around the axis of the lever and push the linear reciprocating rod to move.

[0014] In one specific implementation, the connecting block is slidably connected to the bracket, the bracket is provided with an adjusting component, the adjusting component includes an adjusting motor and a screw, the screw is rotatably connected to the bracket, the connecting block is provided with a screw hole, the screw passes through the screw hole, the screw is threadedly connected to the hole wall of the screw hole, the motor shaft of the adjusting motor is coaxially connected to the screw, and the through hole is an oblong hole.

[0015] By adopting the above technical solution, the motor drives the screw to rotate, and the screw feeds the connecting block bracket, thereby pushing the connecting block to move. Therefore, the lever can move within the through hole, changing the rotation center of the rocker arm, thereby achieving the effect of adjusting the length of the linear reciprocating rod's movement.

[0016] In one specific implementation scheme, the reciprocating rotary table includes a top platform, a bottom platform, a connecting shaft, a locking component, and a circumferential driving component. The bottom platform is rotatably connected to the base. The connecting shaft and the circumferential driving component are both fixedly connected to the bottom platform. The top platform is rotatably connected to the top of the connecting shaft. The circumferential driving component is connected to the top platform. The top platform and the connecting shaft are both detachably connected to the locking component. The reciprocating straight groove is disposed on the bottom platform, and the receiving radar is disposed on the top platform.

[0017] By adopting the above technical solution, when the locking component fixes the top platform to the connecting shaft, the reciprocating drive assembly drives the bottom platform to rotate reciprocally, and both the top platform and the receiving radar can rotate synchronously with the bottom platform. When the locking component is released, the circumferential drive component can drive the top platform to perform a complete circular rotation. Therefore, the millimeter-wave receiver of this application can be used in both environments with obstacles and open environments.

[0018] In one specific implementation scheme, the locking component includes a push-pull lever, an arc-shaped head locking block, and a spring. The top platform has a lever hole, and the top end of the connecting shaft has a locking groove that communicates with the lever hole. The push-pull lever passes through the lever hole, and its bottom end is inserted into the locking groove. Both the lever hole and the locking groove engage with the push-pull lever. The push-pull lever has a horizontal groove, and the arc-shaped head locking block is inserted into the horizontal groove. The spring is located within the horizontal groove, with one end fixedly connected to the groove wall and the other end fixedly connected to the arc-shaped head locking block. The lever hole wall has a first locking hole and a second locking hole sequentially arranged along its length. The arc-shaped head locking block is inserted into either the first or second locking hole.

[0019] By adopting the above technical solution, pushing the push-pull lever pushes its bottom end from the lever hole into the locking slot, causing the lever to engage with both the lever hole and the locking slot simultaneously. At the same time, the arc-shaped locking block inserts into the second locking hole, fixing both the lever and the locking block in this position, preventing further movement. At this point, the top platform can lock with the connecting shaft and rotate synchronously. Pulling the push-pull lever causes the arc-shaped locking block to compress the spring and retract into the transverse groove, fully sliding the bottom end of the lever into the lever hole. The arc-shaped locking block then inserts into the first locking hole, allowing the top platform and the connecting shaft to rotate independently.

[0020] In one specific implementation scheme, the circumferential drive component includes a drive motor, a drive gear, and a drive gear ring. The drive gear ring is sleeved on the push-pull lever and is fixedly connected to the ground of the top platform. The drive motor is fixedly connected to the bottom platform. The drive gear is fixedly connected to the motor shaft of the drive motor and meshes with the drive gear ring.

[0021] By adopting the above technical solution, the drive motor drives the drive gear ring to rotate through the drive gear, and the top platform rotates synchronously with the drive gear ring. At this time, the receiving radar can complete a full circular rotation.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. This application can drive the receiving radar to reciprocate within a set angle, which facilitates the operation of the millimeter-wave receiver in environments with obstacles;

[0024] 2. This application can change the rotation center of the joystick, thereby achieving the effect of adjusting the length of the linear reciprocating lever's movement;

[0025] 3. The millimeter-wave receiver of this application can be used in both obstructed environments and open environments. Attached Figure Description

[0037] This application discloses a millimeter-wave receiver.

[0038] Reference Figure 1 and Figure 2 The millimeter-wave receiver includes a receiving radar 1, a base 2, a reciprocating rotary table 3, and a reciprocating drive assembly 4. The reciprocating rotary table 3 is rotatably connected to the base 2, the reciprocating drive assembly 4 is mounted on the base 2, and the drive end of the reciprocating drive assembly 4 is connected to the reciprocating rotary table 3. The receiving radar 1 is mounted on the reciprocating rotary table 3.

[0039] The reciprocating drive assembly 4 drives the reciprocating rotary table 3 to reciprocate within a set angle, and the receiving radar 1 can follow the reciprocating rotary table 3 to reciprocate, thereby receiving millimeter wave signals normally in environments with obstacles.

[0040] Reference Figure 1 The base 2 includes a box cylinder 21, a box body 22 and a cover plate 23. The box cylinder 21 is integrally connected to the box body 22, and the cover plate 23 covers the top of the box body 22.

[0041] Reference Figure 2 The reciprocating rotary table 3 includes a top table 32, a bottom table 33, a connecting shaft 34, a locking component 35, and a circumferential driving component 36.

[0042] Reference Figure 3 and Figure 4 The base platform 33 includes a frustum 331, a rotating shaft 332, and a bearing 333. The frustum 331 has a central hole 3311, and the bearing 333 is located inside the central hole 3311 and connected to the frustum 331. The rotating shaft 332 is welded vertically to the inner bottom wall of the housing 21, and the top end of the rotating shaft 332 is connected to the bearing 333. The connecting shaft 34 is welded vertically to the upper surface of the frustum 331. The bottom wall of the top platform 32 has a rotating hole 325, and the top end of the connecting shaft 34 is inserted into the rotating hole 325. The inner peripheral wall of the housing 21 has a rotating ring groove 211, and a ball bearing 324 is installed on the peripheral wall of the top platform 32. The peripheral wall of the top platform 32 is inserted into the rotating ring groove 211, and the ball bearing 324 abuts against the groove wall of the rotating ring groove 211.

[0043] The receiving radar 1 is riveted to the upper surface of the top platform 32, and the locking member 35 is connected between the top platform 32 and the connecting shaft 34. The circumferential driving member 36 is mounted on the upper surface of the truncated cone 331.

[0044] Reference Figure 2 and 3 The circumferential drive component 36 includes a drive motor 361, a drive gear 362, and a drive gear ring 363. The drive motor 361 is mounted on a frustum 331. The drive gear 362 is coaxially connected to the motor shaft of the drive motor 361. The drive gear ring 363 is located on the connecting shaft 34. The top end of the drive gear ring 363 is welded to the bottom wall of the top platform 32. The drive gear 362 meshes with the drive gear ring 363.

[0045] Reference Figure 3 and Figure 4The locking component 35 includes a push-pull lever 351, an arc-shaped locking block 352, and a spring 353. The upper surface of the top platform 32 has a vertically extending rod hole 321, which communicates with the rotating hole 325. The bottom end of the rod hole 321 is a cuboid shape. The top wall of the connecting shaft 34 has a cubic locking groove 341, which is opposite to the rod hole 321. The push-pull lever 351 is inserted into the rod hole 321 and abuts against the hole wall.

[0046] The push-pull lever 351 has a horizontal groove 3511 extending in the horizontal direction on its side wall. The arc head block 352 and the spring 353 are both inserted into the horizontal groove 3511. One end of the spring 353 is welded to the end wall of the horizontal groove 3511, and the other end of the spring 353 is welded to the arc head block 352. The arc head block 352 abuts against the peripheral wall of the horizontal groove 3511, and the arc end of the arc head block 352 is away from the spring 353.

[0047] The rod hole 321 has a first locking hole 322 and a second locking hole 323 arranged sequentially from top to bottom on its wall. When the bottom end of the push-pull lever 351 is completely inside the rod hole 321, the arc-shaped end of the arc-shaped head block 352 inserts into the first locking hole 322 and abuts against the hole wall. At this time, the connecting shaft 34 and the top platform 32 rotate independently without interfering with each other. Pushing the push-pull lever 351 downwards causes the arc-shaped head block 352 to compress the spring 353 and slide completely into the transverse groove 3511. When the bottom end of the push-pull lever 351 is inserted into the engaging groove 341 and abuts against the bottom wall of the engaging groove 341, the bottom end of the push-pull lever 351 engages with the engaging groove 341, the top end of the locking block engages with the rod hole 321, and the arc-shaped head block 352 inserts into the second locking hole 323. At this time, the connecting shaft 34 and the top platform 32 rotate synchronously.

[0048] When the connecting shaft 34 and the top platform 32 rotate synchronously, the reciprocating drive assembly 4 is operated to drive the truncated cone 331 to reciprocate within a certain angle. At this time, the top platform 32 and the receiving radar 1 reciprocate within a certain angle, which is convenient for use in environments with obstacles. When the connecting shaft 34 and the top platform 32 rotate separately, the drive motor 361 is started. The drive motor 361 drives the top platform 32 to perform a complete circular motion through the drive gear ring 363. At this time, the receiving radar 1 of this application can rotate 360°, which is convenient for receiving millimeter-wave signals in open environments.

[0049] Reference Figure 3 and Figure 5 The reciprocating drive assembly 4 includes a linear reciprocating rod 41, a drive block 42, a fixed frame 43, and a reciprocating drive component 44. The fixed frame 43 includes a fixed cylinder 431, a bracket 432, a connecting block 433, and a lever 434. The bracket 432 and the fixed cylinder 431 are both riveted to the inner bottom wall of the housing 22.

[0050] A linear reciprocating rod 41 is inserted into a fixed cylinder 431, abutting against the inner wall of the fixed cylinder 431. One end of the linear reciprocating rod 41 passes through the housing 21 and is inserted below the frustum 331. A drive block 42 is welded to the end of the linear reciprocating rod 41 located below the frustum 331. A reciprocating straight groove 31 is provided on the bottom wall of the frustum 331, extending along a diameter of the bottom wall of the frustum 331. The drive block 42 is inserted into the reciprocating straight groove 31 and abuts against the groove wall of the reciprocating straight groove 31.

[0051] Reference Figure 6 and Figure 7 A connecting block 433 is mounted on a bracket 432 and has a circular hole 4332. A lever 434 includes a dumbbell block 4341, a cylinder 4342, and a plug 4343. The cylinder 4342 is inserted into the circular hole 4332 and abuts against the hole wall. The plug 4343 is integrally connected to one end of the cylinder 4342, and the dumbbell block 4341 is integrally connected to the other end of the cylinder 4342. The end of the linear reciprocating rod 41 furthest from the drive block 42 and the dumbbell block 4341 are both rotatably connected to the reciprocating drive component 44.

[0052] The reciprocating drive component 44 includes a drive rod 441, a rocker arm 442, and a power component 443. The power component 443 includes a cam 4431, a power motor 4432, and a transmission block 4433. The power motor 4432 is riveted to the bracket 432, and the cam 4431 is riveted to the motor shaft of the power motor 4432. The rocker arm 442 has a through hole 4421, which is an oblong hole, and its length direction is the same as that of the rocker arm 442. A dumbbell block 4341 is inserted into the through hole 4421 and abuts against the hole wall. The transmission block 4433 is welded to the end of the rocker arm 442 near the cam 4431. The surface of the cam 4431 has a transmission ring groove 4434, the axis of which is not collinear with the axis of the motor shaft of the power motor 4432. The transmission block 4433 is inserted into the transmission ring groove 4434 and abuts against the groove wall.

[0053] One end of the drive rod 441 is rotatably connected to the end of the rocker arm 442 away from the transmission block 4433, and the other end of the drive rod 441 is rotatably connected to the end of the linear reciprocating rod 41 away from the drive block 42.

[0054] The power motor 4432 drives the cam 4431 to rotate eccentrically. The cam 4431 can then apply a thrust to the transmission block 4433, causing the transmission block 4433 to reciprocate towards or away from the power motor 4432. Therefore, the rocker arm 442, driven by the transmission block 4433, reciprocates around the lever 434 within a certain angle, and drives the linear reciprocating rod 41 to reciprocate through the drive rod 441. The linear reciprocating rod 41 drives the frustum 331 and the receiving radar 1 to reciprocate within a certain angle through the drive block 42.

[0055] The bracket 432 has a sliding groove 4323, the length of which is perpendicular to the length of the linear transmission rod. A connecting block 433 is inserted into the sliding groove 4323 and abuts against the groove wall. The connecting block 433 has a screw hole 4331. The bracket 432 has an adjusting component, including an adjusting motor 4321 and a screw 4322. The screw 4322 passes through the screw hole 4331 and is threaded to the hole wall. The end wall of the sliding groove 4323 has an end hole 4324, and one end of the screw 4322 is inserted into the end hole 4324. The bracket 432 has a straight hole 4325 penetrating the sliding groove 4323, and the other end of the screw 4322 protrudes from the straight hole 4325. The adjusting motor 4321 is riveted to the bracket 432, and the motor shaft of the adjusting motor 4321 is coaxially connected to the screw 4322.

[0056] Start the adjusting motor 4321, which drives the screw 4322 to rotate. The screw 4322 then drives the connecting block 433 to slide along the length of the slide groove 4323. Simultaneously, the lever 434 slides within the oblong hole. When the lever 434 moves closer to the transmission block 4433, the swing amplitude of the end of the rocker arm 442 away from the transmission block 4433 is increased. Therefore, the moving distance of the linear reciprocating rod 41 increases, and the rotation angle of the frustum 331 and the receiving radar 1 also increases. When the lever 434 moves away from the transmission block 4433, the swing amplitude of the end of the rocker arm 442 away from the transmission block 4433 is decreased. Therefore, the rotation angle of the receiving radar 1 is decreased.

[0057] The implementation principle of a millimeter-wave receiver according to this application embodiment is as follows: When using the millimeter-wave receiver of this embodiment in an environment with obstacles, first push down the push-pull lever 351. When the lower end of the push-pull lever 351 is inserted into the locking slot 341, stop pushing the push-pull lever 351. At this time, the arc-shaped locking block 352 is inserted into the second locking hole 323.

[0058] Then, the power motor 4432 is started, which drives the cam 4431 to rotate. The cam 4431 drives the rocker arm 442 to swing back and forth. The rocker arm 442 drives the linear reciprocating rod 41 to reciprocate along a straight line through the drive rod 441. The linear reciprocating rod 41 drives the truncated cone 331 to rotate back and forth within a certain angle through the drive block 42. The top platform 32 and the receiving radar 1 rotate synchronously with the truncated cone 331. The receiving radar 1 can then swing back and forth in the direction where there are no obstacles to receive millimeter wave signals.

[0059] When the millimeter-wave receiver of this embodiment is used in an open environment, first pull the push-pull lever 351 upward. When the bottom end of the push-pull lever 351 is completely slid into the receiving slot, stop pulling the push-pull lever 351. At this time, the arc-shaped head locking block 352 is inserted into the first locking hole 322.

[0060] Then start the drive motor 361, drive motor 361 drives drive gear 362 to rotate, drive gear 362 drives drive ring 363 to rotate, the top platform 32 and receiving radar 1 make a complete circular motion, and receiving radar 1 can receive millimeter wave signals 360°.

[0061] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
