Description

Technical Field

[0001] The present invention relates to a base, in particular to a three-dimensional control displacement base for a Beidou receiver. Background Art

[0002] A BeiDou receiver is an electronic device used to receive, decode, and process signals from China's independently developed BeiDou Navigation Satellite System (BDS). By receiving navigation signals transmitted by BeiDou satellites, it calculates the user's position, velocity, and time, and is widely used in navigation and positioning applications.

[0003] During use, a Beidou receiver must be placed on a base. To maintain signal strength during measurement or navigation tasks, the spatial position of the receiver antenna must be precisely adjusted. Common Beidou receiver bases rely on a self-locking lead screw to prevent the receiver from falling during Z-axis adjustment. However, the sliding friction of this self-locking lead screw can easily lead to stick-slip, resulting in unstable movement at low speeds and making it impossible to secure the Beidou receiver at a specific height. Summary of the Invention

[0004] The main purpose of the present invention is to provide a three-dimensional control displacement base for a Beidou receiver to solve the problems raised in the related art.

[0005] To achieve the above object, according to one aspect of the present invention, a Beidou receiver three-dimensional control displacement base is provided, comprising a top plate for placing the Beidou receiver, and further comprising: an X-axis transmission portion, the X-axis transmission portion being disposed below the top plate and configured to control the movement of the top plate along the X-axis direction; A Y-axis transmission part is provided below the top plate and is used to control the movement of the top plate along the Y-axis direction; A Z-axis transmission part is provided below the top plate and is used to control the movement of the top plate along the Z-axis direction; The locking portion is used to prevent the Z-axis transmission portion from rotating when not subjected to external force.

[0006] Furthermore, a lower box body is provided outside the Y-axis transmission part and the X-axis transmission part, a Y-axis encoder and an X-axis encoder are fixedly provided on the side of the lower box body, a support plate is slidably provided on the top of the lower box body, and an upper box body is fixed on the top of the support plate.

[0007] Furthermore, a Z-axis encoder is fixedly provided on the side of the upper box body, a circular groove is provided on the side of the upper box body, a plurality of inclined fixed teeth are provided in the circular groove, the fixed teeth are fixedly connected to the upper box body, and a plurality of receiving holes inclined in the opposite direction to the fixed teeth are provided on the side surface of the fixed teeth.

[0008] Furthermore, the X-axis transmission part includes an X-axis handwheel, an X-axis screw is fixedly provided on the inner side of the X-axis handwheel, an X-axis sleeve is provided on the outer ring of the X-axis screw, and the X-axis screw is threadedly connected to the X-axis sleeve.

[0009] Furthermore, the Y-axis transmission part includes a Y-axis handwheel, a Y-axis lead screw is fixedly provided on the inner side of the Y-axis handwheel, a Y-axis sleeve is provided on the outer ring of the Y-axis lead screw, and the Y-axis lead screw is threadedly connected to the Y-axis sleeve.

[0010] Furthermore, the Z-axis transmission part includes a Z-axis handwheel, a Z-axis connecting rod is provided on the inner side of the Z-axis handwheel, a worm is fixedly provided at the rear end of the Z-axis connecting rod, a worm wheel is provided on one side of the worm, the worm is meshed with the worm wheel, and a Z-axis lead screw is fixedly provided inside the worm wheel.

[0011] Furthermore, the locking portion includes a movable tooth fixedly provided on the inner side of the Z-axis handwheel and tilted, and a plurality of convex teeth tilted in the opposite direction to the movable tooth are fixedly provided on the side surface of the movable tooth.

[0012] Furthermore, the movable teeth can be inserted into the gap between two adjacent fixed teeth.

[0013] Furthermore, a through channel is provided in the middle of the Z-axis handwheel, a plurality of arc-shaped grooves are provided in the middle of the channel, longitudinal grooves are provided on the outside of the arc-shaped grooves, a receiving groove is provided on the rear side of the Z-axis handwheel, a connecting ring is provided for rotation in the receiving groove, and a spring is fixed on the outside of the connecting ring.

[0014] Furthermore, a collar is fixedly provided at the other end of the spring, and the collar is fixedly sleeved on the outer ring of the Z-axis connecting rod. A plurality of bosses are fixedly provided at one end of the Z-axis connecting rod close to the Z-axis handwheel.

[0015] Compared with the prior art, the present invention has the following beneficial effects: This invention prevents the top plate from falling back by providing a locking mechanism, thereby securing the Beidou receiver at the designed position. The tilted fixed and movable teeth engage with each other, increasing their contact area and the resistance of the fixed teeth to the movable teeth, thereby preventing the Z-axis handwheel from rotating and locking it. The boss and longitudinal groove cooperate to link the Z-axis connecting rod and the Z-axis handwheel. When the handwheel is locked, the connecting rod is simultaneously fixed, preventing the Z-axis transmission unit from changing the height of the top plate, and securing the Beidou receiver at the designed height.

[0016] The locking mechanism is separate from the Z-axis drive. When adjusting the Beidou receiver's height, the locking mechanism remains unlocked, preventing adjustment of the Z-axis drive. Once the Beidou receiver reaches the desired position, the locking mechanism locks, preventing further Z-axis adjustment. These two mechanisms prevent interference, ensuring the Beidou receiver remains fixed at a specific height. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] A lower box body 1 is provided outside the Y-axis transmission part 6 and the X-axis transmission part 7.

[0030] The Z-axis encoder 14, Y-axis encoder 15 and X-axis encoder 16 all use Changchun Yuheng JZ-20 incremental grating encoders, which are used to convert the displacement of the Z-axis, X-axis and Y-axis into electrical signals and display them on the encoder, making it easy to read the displacement values of each axis.

[0031] like Figure 4 The X-axis transmission part 7 shown includes an X-axis handwheel 72, an X-axis handle 71 is rotatably provided on the outside of the X-axis handwheel 72, an X-axis screw 73 is fixedly provided on the inside of the X-axis handwheel 72, an X-axis sleeve 74 is provided on the outer ring of the X-axis screw 73, the X-axis screw 73 is threadedly connected to the X-axis sleeve 74, the X-axis sleeve 74 is fixedly provided on the X-axis base frame 75, and the X-axis base frame 75 is slidably connected to the bottom of the lower box body 1.

[0032] Turn the X-axis handle 71, and the X-axis handle 71 drives the X-axis screw 73 to rotate through the X-axis handwheel 72. The X-axis screw 73 drives the X-axis sleeve 74 to reciprocate along the X-axis direction. The X-axis sleeve 74 drives the Y-axis transmission unit 6 to reciprocate along the X-axis direction through the X-axis base 75. The Y-axis transmission unit 6 drives the top plate 4 to reciprocate in the X-axis direction through the Z-axis transmission unit 5, and adjusts the Beidou receiver to the X-axis set position.

[0033] The Y-axis transmission part 6 includes a Y-axis handwheel 62, a Y-axis handle 61 is rotatably provided on the outside of the Y-axis handwheel 62, a Y-axis screw 63 is fixedly provided on the inside of the Y-axis handwheel 62, a Y-axis sleeve 64 is provided on the outer ring of the Y-axis screw 63, the Y-axis screw 63 is threadedly connected to the Y-axis sleeve 64, the Y-axis sleeve 64 is fixedly provided on the Y-axis base frame 65, the bottom of the Y-axis base frame 65 is fixedly connected to the X-axis base frame 75, and the top is fixedly provided with a Y-axis connecting plate 66, and the Y-axis connecting plate 66 is fixedly connected to the support plate 2.

[0034] Turn the Y-axis handle 61, and the Y-axis handle 61 drives the Y-axis screw 63 to rotate through the Y-axis handwheel 62. The Y-axis screw 63 drives the Y-axis sleeve 64 to reciprocate in the Y-axis direction. The Y-axis sleeve 64 drives the Z-axis transmission part 5 to reciprocate in the Y-axis direction through the Y-axis connecting plate 66. The Z-axis transmission part 5 drives the top plate 4 to reciprocate in the Y-axis direction to adjust the Beidou receiver to the Y-axis set position.

[0035] like Figure 3 As shown, a protection box 8, a bottom support plate 9, a top support plate 10, a plurality of bottom guide rods 11, a sleeve 12 and a plurality of top guide rods 13 are provided inside the upper box body 3.

[0036] The protection box 8 is fixed on the support plate 2, the outer edge of the bottom support plate 9 is fixedly connected to the inner wall of the upper box body 3, the outer edge of the top support plate 10 is slidably connected to the inner wall of the upper box body 3, the lower end of the sleeve 12 passes through the bottom support plate 9 and is slidably connected to the bottom support plate 9, and the top is fixedly connected to the top support plate 10, the top ends of the bottom guide rods 11 are fixedly connected to the top support plate 10, and the lower ends pass through the bottom support plate 9 and are slidably connected to the bottom support plate 9. The bottom guide rods 11 are used to limit the rotation of the bottom support plate 9. The bottom end of the bottom guide rods 11 extends below the bottom support plate 9, and the bottom end of the bottom guide rods 11 is fixedly provided with a baffle to prevent the bottom guide rods 11 from detaching from the bottom support plate 9 and losing the restriction on the bottom support plate 9. The tops of the top guide rods 13 are fixedly connected to the top plate 4, and the lower ends are fixedly connected to the top support plate 10.

[0037] like Figure 5 The Z-axis transmission part 5 shown includes a Z-axis handwheel 52, a Z-axis handle 51 is rotatably provided on the outer side of the Z-axis handwheel 52, a Z-axis connecting rod 53 is provided on the inner side of the Z-axis handwheel 52, a worm 54 is fixedly provided at the rear end of the Z-axis connecting rod 53, a worm wheel 55 is provided on one side of the worm 54, the worm 54 is meshed with the worm wheel 55, and a Z-axis lead screw 56 is fixed inside the worm wheel 55.

[0038] The Z-axis screw 56 is sleeved in the sleeve 12. The inner ring of the sleeve 12 is provided with a thread, which engages with the Z-axis screw 56. When the Z-axis screw 56 rotates, it drives the sleeve 12 to move up and down. The sleeve 12 drives the top plate 4 to move up and down through the top support plate 10 and the top guide rod 13, thereby adjusting the height of the Beidou receiver.

[0039] like Figure 8 As shown, the locking portion includes a movable tooth 521 fixedly provided on the inner side of the Z-axis hand wheel 52 and tilted, and a plurality of protruding teeth 526 tilted in the opposite direction to the movable tooth 521 are fixedly provided on the side surface of the movable tooth 521 .

[0040] The inclination direction of the fixed teeth 32 and the movable teeth 521 is opposite to the rotation direction of the Z-axis handwheel 52 when the top plate 4 descends. When the top plate 4 descends and drives the Z-axis handwheel 52 to rotate, the movable teeth 521 are inserted into the gap between two adjacent fixed teeth 32. The fixed teeth 32 clamp the movable teeth 521, preventing the Z-axis handwheel 52 from rotating. The inclined fixed teeth 32 and the movable teeth 521 increase the contact area between the two, thereby increasing the resistance of the fixed teeth 32 to the movable teeth 521.

[0041] The movable teeth 521 can be inserted into the gap between two adjacent fixed teeth 32. The fixed teeth 32 hinder the rotation of the movable teeth 521, thereby preventing the Z-axis handwheel 52 from rotating, fixing the Beidou receiver at a set height, and preventing it from falling back. The reversely inclined convex teeth 526 can cooperate with the corresponding reversely inclined receiving holes 33 to increase the friction between the fixed teeth 32 and the movable teeth 521, further increasing the resistance of the fixed teeth 32 to the movable teeth 521.

[0042] like Figure 7 As shown, a through hole 523 is provided in the middle of the Z-axis handwheel 52, and the Z-axis connecting rod 53 can slide in the hole 523. A plurality of arc-shaped grooves 525 are provided in the middle of the hole 523, and longitudinal grooves 524 are provided on the outside of the arc-shaped grooves 525. When the boss 50 is located in the corresponding longitudinal groove 524, the Z-axis connecting rod 53 can slide back and forth in the hole 523; when the boss 50 is aligned with the arc-shaped groove 525, the boss 50 can slide in the arc-shaped groove 525, thereby causing the Z-axis connecting rod 53 to rotate in the hole 523; when the boss 50 rotates to the edge of the arc-shaped groove 525, the Z-axis connecting rod 53 can no longer rotate and will rotate synchronously with the Z-axis handwheel 52; a receiving groove 522 is provided on the rear side of the Z-axis handwheel 52, and a connecting ring 59 is provided for rotation in the receiving groove 522, and a spring 58 is fixed on the outside of the connecting ring 59.

[0043] The end of the longitudinal groove 524 away from the arc-shaped groove 525 is located inside the Z-axis handwheel 52. When the boss 50 slides in the longitudinal groove 524, it will not fall out of the Z-axis handwheel 52. When the boss 50 is located at the end of the longitudinal groove 524 away from the arc-shaped groove 525, the Z-axis handwheel 52 is located in the circular groove 31, and the locking portion is in a locked state. The Z-axis handwheel 52 cannot rotate. Since the boss 50 is in the longitudinal groove 524, the longitudinal groove 524 restricts the rotation of the boss 50. Therefore, the Z-axis connecting rod 53 is confined in the Z-axis handwheel 52 and is fixed together with the Z-axis handwheel 52, preventing the top plate 4 from falling back due to the reverse rotation of the Z-axis connecting rod 53.

[0044] like Figure 6 The other end of the spring 58 is fixed with a collar 57 , and the collar 57 is fixedly sleeved on the outer ring of the Z-axis connecting rod 53 . A plurality of bosses 50 are fixed on one end of the Z-axis connecting rod 53 close to the Z-axis handwheel 52 .

[0045] When the locking part is in the locked state, the Z-axis handwheel 52 is located in the circular groove 31, and the fixed teeth 32 and the movable teeth 521 are engaged with each other. At this time, the boss 50 is facing the longitudinal groove 524, and the spring 58 contracts, pulling the Z-axis handwheel 52 toward the circular groove 31. The Z-axis connecting rod 53 slides along the channel 523, and the boss 50 slides along the longitudinal groove 524.

[0046] When the height of the top plate 4 needs to be adjusted, the Z-axis handwheel 52 is pulled outward, the boss 50 slides along the longitudinal groove 524 to the arc-shaped groove 525, the spring 58 is stretched, and the Z-axis handwheel 52 is rotated so that the boss 50 rests against the side of the rear end of the arc-shaped groove 525 along the rotation direction of the Z-axis handwheel 52, and the boss 50 is stuck in the arc-shaped groove 525, so that the Z-axis connecting rod 53 can rotate synchronously with the Z-axis handwheel 52.

[0047] Rotate the Z-axis handle 51 to drive the Z-axis handwheel 52 to rotate. The Z-axis handwheel 52 drives the Z-axis connecting rod 53 to rotate through the boss 50. The Z-axis connecting rod 53 drives the worm 54 to rotate. The worm 54 drives the worm gear 55 to rotate. The worm gear 55 drives the Z-axis lead screw 56 to rotate, thereby raising or lowering the sleeve 12 to change the height of the top plate 4 and fix the Beidou receiver at the set Z-axis position.

[0048] After the top plate 4 is adjusted to the designed height, stop rotating the Z-axis handle 51 and rotate the Z-axis handwheel 52 in the opposite direction. Since the connecting ring 59 is rotationally connected to the Z-axis handwheel 52, when the Z-axis handwheel 52 is rotated in the opposite direction, the Z-axis connecting rod 53 will not be driven to rotate, so the top plate 4 maintains its original height. Reverse the Z-axis handwheel 52 to turn the longitudinal groove 524 to the convex column 50, slowly release the Z-axis handwheel 52, and the spring 58 contracts to pull the Z-axis handwheel 52 into the circular groove 31. The fixed teeth 32 and the movable teeth 521 engage with each other to prevent the movable teeth 521 from rotating, thereby enhancing the locking ability of the locking part; the receiving hole 33 and the convex teeth 526 increase the friction between the fixed teeth 32 and the movable teeth 521, thereby preventing the movable teeth 521 from falling off from the fixed teeth 32, thereby further enhancing the locking ability of the locking part.

[0049] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as above in terms of a preferred embodiment, it is not intended to limit the present invention. Any person skilled in the art can, without departing from the scope of the technical solution of the present invention, make some changes or modifications to equivalent embodiments using the technical contents disclosed above. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
