Description

Technical Field

[0001] This utility model relates to the field of geographic information measurement instruments, and more specifically, to a laser module and lens adjustment mechanism and an RTK device. Background Technology

[0002] With the advancement of RTK (Real-Time Kinematic) technology, the methods for measuring geographic information have become more diversified. Photogrammetry and laser measurement technologies are being integrated into RTK measurement. However, given the inherent errors in manufacturing and assembly precision, the long-distance measurement method of laser measurement amplifies these errors by hundreds or thousands of times, resulting in measurement accuracy that cannot meet high-precision requirements. Currently, laser modules and lens modules in RTK equipment are typically fixed in place using screws. Directly fixing these modules to different manufacturing and assembly precision levels can easily affect the accuracy of RTK laser measurement. To meet the accuracy requirements, the installation positions of laser modules and lens modules in each RTK device need to be adaptively adjusted. However, since the RTK equipment casing is mass-produced, this increases production costs. Utility Model Content

[0003] This invention aims to overcome the drawback that direct fixed installation of laser modules and lens modules with different manufacturing and assembly precision can easily affect the accuracy of RTK laser measurement. It provides a laser module and lens adjustment mechanism and an RTK device.

The lens module is mounted on the lens module bracket and is located on one side of the laser module. The lens module bracket is horizontally rotatably connected to the second rotating shaft via a lens module connection hole. The laser module bracket and the lens module bracket each have a first mounting hole and a second mounting hole, respectively, for adjusting the angles of the laser module and the lens module, and then fixing them to the base with screws through the first mounting hole and the second mounting hole, respectively.

[0006] In this technical solution, the laser module and the lens module are respectively mounted on the base using a laser module bracket and a lens module bracket. The laser module bracket is rotatably connected to the base via a first rotating shaft, enabling the laser module to be adjusted in the horizontal direction. The lens module bracket is rotatably connected to the base via a second rotating shaft, enabling the lens module to be adjusted in the horizontal direction.

[0007] During assembly, the lens module is first installed on the lens module bracket.

Then, the lens module bracket is fixed to the base using screws through the second mounting hole, completing the installation of the lens module. Next, the laser module is installed on the laser module bracket. After connecting the laser module bracket to the first rotating shaft, the actual laser irradiation point emitted by the laser module is adjusted to within the specified range of the target laser irradiation point marked in the lens image. Finally, the laser module bracket is fixed to the base using screws through the first mounting hole, completing the installation of the laser module and achieving joint installation and debugging of the laser module and lens module.

[0008] As a preferred embodiment, the laser module bracket includes a vertical wall and a support.

A laser module mounting hole is provided on the vertical wall for fixing the laser module to the vertical wall after adjusting the angle by fixing screws. A laser module connection hole is provided on the support.

[0009] As a preferred embodiment, a third rotating shaft is provided on the vertical wall; a rotating shaft connection hole matching the third rotating shaft is provided on the laser module, and the laser module is rotatably connected to the third rotating shaft through the rotating shaft connection hole.

[0010] As a preferred embodiment, at least two threaded holes are provided on the transverse wall, and fasteners are provided in the threaded holes; one end of the fastener abuts against the laser module installed on the vertical wall through the threaded hole, and the other end of the fastener extends out of the threaded hole.

[0011] As a preferred embodiment, the two sides of the transverse wall are provided with first extension portions extending outward; the first mounting hole is provided on the first extension portion for fixed connection with the base.

[0012] As a preferred option, the first mounting hole is an oval hole structure, which facilitates fine adjustments to the laser module bracket.

[0013] As a preferred embodiment, the lower surface of the vertical wall extends outward to form a second extension portion; the second extension portion has a third mounting hole for fixed connection with the base.

[0014] As a preferred embodiment, the laser module bracket further includes a cover plate, on which a through hole is provided at a position matching the laser module mounting hole, for fixing the laser module after angle adjustment by means of a fixing screw through the through hole and the laser module mounting hole.

[0015] As a preferred embodiment, an elastic pad is provided between the lens module bracket and the base for adjusting the tilt angle of the lens module bracket.

[0017] Compared with the prior art, the beneficial effects of this utility model's technical solution are:

[0018] This invention utilizes a laser module bracket and a lens module bracket to mount the laser module and lens module on a base, respectively. With the assistance of a first and second rotating shaft, the lateral angle of the laser module and lens module is adjusted. This allows the center point of the lens module's image to be aligned with the target area within the target, and the actual laser irradiation point emitted by the laser module to be aligned with the specified target laser irradiation point position marked in the lens image.

[0032] Please see Figure 1This embodiment proposes a laser module and lens integration mechanism, including a laser module 1, a lens module 2, a laser module bracket 3, a lens module bracket 4, and a base 5 for mounting the laser module 1 and the lens module 2.

[0033] The base 5 is provided with a first rotating shaft 501 and a second rotating shaft 502. The laser module 1 is mounted on the laser module bracket 3. The laser module bracket 3 is horizontally rotatably connected to the first rotating shaft 501 through a laser module connection hole 311. The lens module 2 is mounted on the lens module bracket 4 and is located on one side of the laser module 1. The lens module bracket 4 is horizontally rotatably connected to the second rotating shaft 502 through a lens module connection hole 401.

[0034] The laser module bracket 3 and the lens module bracket 4 are respectively provided with a first mounting hole 312 and a second mounting hole 402, which are used to fix the laser module 1 and the lens module 2 to the base 5 by screws through the first mounting hole 312 and the second mounting hole 402 respectively after the angle adjustment is completed.

[0035] During assembly, lens module 2 is first installed on lens module bracket 4. After connecting lens module bracket 4 to the second rotating shaft 502, its lateral angle is adjusted to align the center point of the lens image with the target area in the target. Then, lens module bracket 4 is fixed to base 5 with screws through the second mounting hole 402, completing the installation of lens module 2. Next, laser module 1 is installed on laser module bracket 3. After connecting laser module bracket 3 to the first rotating shaft 501, the actual laser irradiation point emitted by laser module 1 is adjusted to within the specified range of the target laser irradiation point marked in the lens image. Then, laser module bracket 3 is fixed to base 5 with screws through the first mounting hole 312, completing the installation of laser module 1 and achieving joint installation and debugging of laser module 1 and lens module 2.

[0036] In this embodiment, laser module 1 and lens module 2 are mounted on base 5 using laser module bracket 3 and lens module bracket 4, respectively. Laser module bracket 3 is rotatably connected to base 5 via first rotating shaft 501, enabling horizontal angle adjustment of laser module 1. Lens module bracket 4 is rotatably connected to base 5 via second rotating shaft 502, enabling horizontal angle adjustment of lens module 2. This allows for adaptive assembly of laser module 1 and lens module 2 with different assembly precisions on mass-produced mounting base 5, thereby improving the accuracy of RTK laser measurement.

[0037] Example 2

[0038] This embodiment further explains the laser module and lens adjustment mechanism proposed in Embodiment 1.

[0039] The laser module and lens linkage mechanism proposed in this embodiment includes a laser module 1, a lens module 2, a laser module bracket 3, a lens module bracket 4, and a base 5 for mounting the laser module 1 and the lens module 2. The base 5 is provided with a first rotating shaft 501 and a second rotating shaft 502. The laser module 1 is mounted on the laser module bracket 3, and the laser module bracket 3 is horizontally rotatably connected to the first rotating shaft 501 through a laser module connection hole 311. The lens module 2 is mounted on the lens module bracket 4 and is located on one side of the laser module 1. The lens module bracket 4 is horizontally rotatably connected to the second rotating shaft 502 through a lens module connection hole 401. The laser module bracket 3 and the lens module bracket 4 are respectively provided with a first mounting hole 312 and a second mounting hole 402, for adjusting the angles of the laser module 1 and the lens module 2, and then fixing them to the base 5 with screws through the first mounting hole 312 and the second mounting hole 402, respectively.

[0040] In an optional embodiment, the laser module bracket 3 includes a horizontal wall 310 and a vertical wall 320, the horizontal wall 310 being disposed on the upper surface of the vertical wall 320; the vertical wall 320 is provided with a laser module mounting hole 321 for fixing the laser module 1, which has been angled and adjusted, to the vertical wall 320 by fixing screws; the laser module connection hole 311 is provided on the horizontal wall 310.

[0041] For example, such as Figure 2 The diagram shown is a structural schematic of the laser module bracket 3 in this embodiment.

[0042] In this embodiment, the vertical wall 320 serves as a mounting base for mounting and fixing the laser module 1; the horizontal wall 310 is used to connect and fix the laser module bracket 3 to the base 5 as a whole.

[0043] In the specific implementation process, the laser module 1 is first placed on the vertical wall 320. By adjusting the pitch angle of the laser module 1, the actual laser irradiation point emitted by the laser module 1 is adjusted to within the specified range of the target laser irradiation point position marked in the lens image. Then, the laser module 1, after angle adjustment, is fixed to the vertical wall 320 using fixing screws. Further, by adjusting the horizontal angle of the laser module bracket 3 around the first rotating axis 501, the actual laser irradiation point emitted by the laser module 1 is adjusted to within the specified range of the target laser irradiation point position marked in the lens image. Finally, the laser module bracket 3 is fixed to the base 5 using screws through the first mounting hole 312, completing the installation of the laser module 1.

[0044] The fixing screw passes through the laser module 1 and the laser module mounting hole 321, and then cooperates with the nut to achieve pre-locking, ensuring that the laser module 1 is still in a rotatable state.

[0045] Furthermore, in an optional embodiment, a third rotating shaft 322 is provided on the vertical wall 320; a rotating shaft connection hole 101 matching the third rotating shaft 322 is provided on the laser module 1, and the laser module 1 is rotatably connected to the third rotating shaft 322 through the rotating shaft connection hole 101.

[0046] In this embodiment, the laser module 1 is rotatably connected to the third rotating shaft 322 through the rotating shaft connection hole 101, thereby realizing the adjustment of the pitch angle of the laser module 1.

[0047] Specifically, firstly, the laser module 1 is rotatably connected to the third rotating shaft 322 on the vertical wall 320 through its rotating shaft connection hole 101, and the pitch angle is adjusted around the third rotating shaft 322 so that the actual laser irradiation point emitted by the laser module 1 is adjusted to the specified range of the target laser irradiation point position marked in the lens image. Then, the laser module 1, after the angle adjustment, is fixed to the vertical wall 320 by fixing screws, thus completing the assembly between the laser module 1 and the laser module bracket 3.

[0048] Furthermore, in an optional embodiment, at least two threaded holes 313 are provided on the transverse wall 310, and fasteners 6 are provided in the threaded holes 313; one end of the fastener 6 abuts against the laser module 1 installed on the vertical wall 320 through the threaded hole 313, and the other end of the fastener 6 extends out of the threaded hole 313.

[0049] For example, such as Figure 3 The image shown is an exploded view of laser module 1 in this embodiment.

[0050] For example, the transverse wall 310 is provided with two threaded holes 313, and the two threaded holes 313 are optionally provided on the transverse wall 310 and on both sides of the third rotating shaft 322.

[0051] In this embodiment, the fastener 6, which is provided through the threaded hole 313, is used to adjust and limit the vertical rotation of the laser module 1.

[0052] Alternatively, the fastener 6 may be a nut screw.

[0053] For example, during implementation, the grating screw is passed through the threaded hole 313 to press against one side of the laser module 1 mounted on the vertical wall 320. When it is necessary to make a fine adjustment to the pitch angle of the laser module 1, the grating screw can be turned.

[0054] In an optional embodiment, the two sides of the transverse wall 310 are provided with first extension portions 330 extending outward; the first mounting hole 312 is provided on the first extension portion 330 for fixed connection with the base 5.

[0055] For example, such as Figure 4 The diagram shown is a structural schematic of the transverse wall 310 in this embodiment.

[0056] In this embodiment, the extension provided on the transverse wall 310 is fixedly connected to the base 5, which further ensures the installation stability of the laser module 1 and prevents the laser module bracket 3 from becoming loose during use.

[0057] Alternatively, the first mounting hole 312 may be an oval hole structure.

[0058] In this embodiment, an oval hole structure is selected as the mounting hole, and the axis of the center of the oval hole coincides with the first rotating shaft 501, providing adjustment margin for the lateral rotation of the laser module 1.

[0059] The laser module 1 is connected to the corresponding screw hole on the base 5 through the first mounting hole 312 without being locked, so that the laser module 1 can rotate slightly around the first rotating shaft 501.

[0060] Furthermore, in an optional embodiment, the lower surface of the vertical wall 320 is provided with a second extension 340 extending outward; the second extension 340 is provided with a third mounting hole 341 for fixed connection with the base 5.

[0061] In this embodiment, the first extension 330 provided at the top of the transverse wall 310 is connected and fixed to the upper part of the base 5, while the second extension 340 provided at the bottom of the transverse wall 310 is connected and fixed to the bottom of the base 5, further preventing the laser module bracket 3 from becoming loose during use.

[0062] Alternatively, the third mounting hole 341 is an oval hole structure, providing adjustment margin for the lateral rotation of the laser module 1.

[0063] In an optional embodiment, the laser module bracket 3 further includes a cover plate 350, on which a through hole is provided at a position matching the laser module mounting hole 321, for fixing the laser module 1, which has been angle-adjusted, through the through hole and the laser module mounting hole 321 by a fixing screw.

[0064] In this embodiment, the cover plate 350 is locked onto the transverse wall 310 by fixing screws, thereby enclosing the laser module 1 and serving to fix it and provide electromagnetic shielding.

[0065] Alternatively, the cover plate 350 may also be provided with several through holes for fixed connection with the transverse wall 310.

[0066] Example 3

[0067] This embodiment further explains the laser module and lens adjustment mechanism proposed in Embodiments 1 and 2.

[0068] The laser module and lens linkage mechanism proposed in this embodiment includes a laser module 1, a lens module 2, a laser module bracket 3, a lens module bracket 4, and a base 5 for mounting the laser module 1 and the lens module 2. The base 5 is provided with a first rotating shaft 501 and a second rotating shaft 502. The laser module 1 is mounted on the laser module bracket 3, and the laser module bracket 3 is horizontally rotatably connected to the first rotating shaft 501 through a laser module connection hole 311. The lens module 2 is mounted on the lens module bracket 4 and is located on one side of the laser module 1. The lens module bracket 4 is horizontally rotatably connected to the second rotating shaft 502 through a lens module connection hole 401. The laser module bracket 3 and the lens module bracket 4 are respectively provided with a first mounting hole 312 and a second mounting hole 402, for adjusting the angles of the laser module 1 and the lens module 2, and then fixing them to the base 5 with screws through the first mounting hole 312 and the second mounting hole 402, respectively.

[0069] Furthermore, in this embodiment, an elastic pad 7 is provided between the lens module bracket 4 and the base 5.

[0070] For example, such as Figure 5 , 6 The diagram shown is a schematic diagram of the lens module 2 mounting structure and a schematic diagram of the lens module bracket 4 in this embodiment.

[0071] For example, the lens module bracket 4 is an L-shaped bracket. The lens module 2 is mounted on one side of the lens module bracket 4, and the other side of the lens module 2 has a lens module connection hole 401 and a second mounting hole 402. The lens module bracket 4 is rotatably connected to the second rotating shaft 502 provided on the base 5 through its lens module connection hole 401.

[0072] In this embodiment, the elastic shim 7 is sleeved on the second rotating shaft 502 and between the lens module bracket 4 and the base 5, and is used to provide elastic force to the lens module 2. During the assembly of the lens module 2, the adjusting screw passes through the lens module bracket 4 and the elastic shim 7 in sequence and is pre-locked to the second mounting hole 402 opened on the base 5. At this time, the elastic shim 7 provides adjustment margin for the adjustment of the lens module 2.

[0073] Furthermore, by adjusting the lateral and tilt angles of the lens module 2, the center point of the lens image is adjusted to the target range in the target, and then the adjusting screws are fixed with glue, thus completing the assembly of the lens module 2.
