Description

Technical Field

[0001] This utility model relates to the field of remote sensing mapping technology, specifically a remote sensing mapping positioning device. Background Technology

[0002] Vehicle-mounted remote sensing equipment is a system installed on a vehicle for remotely sensing and collecting environmental information. Existing vehicle-mounted remote sensing equipment installed in cars is mostly mounted and secured via a roof rack. While the vehicle is in motion, the equipment needs buffering to reduce the impact of bumps and turns. However, this buffering structure causes the equipment to shift relative to the roof rack, and when the vehicle is stationary, a stable connection cannot be guaranteed, affecting the consistency of results in repeated surveying operations. Therefore, a positioning structure is needed on the roof rack to ensure the remote sensing equipment is securely fixed when the vehicle is stationary. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a remote sensing mapping and positioning device that can reliably fix the remote sensing equipment on the roof frame when the vehicle is stationary.

[0004] To solve the above problems, the technical solution adopted by this utility model is as follows:

[0005] A remote sensing mapping and positioning device, comprising:

[0006] The roof frame consists of two parallel, symmetrical crossbeams;

[0007] Two sets of support components are respectively disposed on two crossbeams. Each support component includes two support seats spaced apart. Each support seat includes a first clamping assembly detachably disposed on the crossbeam, a support plate disposed on the first clamping assembly, a spring buffer assembly disposed on the support plate, and a buffer plate disposed on the spring buffer assembly.

[0008] A base plate, set on the four sets of buffer plates, is used to mount and fix remote sensing equipment;

[0009] Two sets of substrate lifting mechanisms are symmetrically arranged on both sides of the substrate to control the lifting of the substrate. A frustum groove is provided on the support plate, and a frustum is provided on the buffer plate corresponding to the frustum groove. When the substrate descends, the frustum descends to engage with the frustum groove, thereby positioning the substrate at its horizontal position after descending.

[0010] As one embodiment of the present invention, the substrate lifting mechanism includes a lifting fixed seat located between the two support seats and an electric cylinder disposed on the substrate;

[0011] The lifting and fixing base includes two second clamping assemblies spaced apart on the crossbeam and a fixing plate disposed on the two second clamping assemblies. The fixing plate has a fixing plate through hole. The output rod end of the electric cylinder passes through the base plate and the fixing plate through hole and is connected to a limit plate. The electric cylinder drives the output rod to retract, so that the limit plate presses against the fixing plate, thereby causing the base plate to press against the spring buffer assembly and descend toward the fixing plate. The electric cylinder drives the output rod to extend, so that the base plate rises and resets under the support of the spring buffer assembly.

[0012] In one embodiment of this utility model, the size of the limiting plate is larger than the size of the through hole of the fixing plate, and the size of the through hole of the fixing plate is larger than the size of the output rod, so that the output rod can move horizontally relative to the through hole of the fixing plate.

[0013] As one embodiment of the present invention, the first clamping assembly includes a first supporting clamping body and a second supporting clamping body;

[0014] The first support clamp includes a first clamp bend and a first clamp vertical part disposed on the first clamp bend. The shape and size of the cross section of the first clamp bend correspond to the shape and size of the cross section on one side of the crossbeam. The support plate is disposed on the first clamp vertical part.

[0015] The second support clamp includes a second clamp bend and a second clamp vertical part disposed on the second clamp bend. The shape and size of the cross section of the second clamp bend correspond to the shape and size of the cross section on the other side of the crossbeam.

[0016] The first clamping vertical portion and the second clamping vertical portion are respectively connected by bolt assemblies so that the first clamping vertical portion and the second clamping bent portion are clamped and fixed on the crossbeam.

[0017] In one embodiment of this utility model, a guide tube is centrally disposed on the support plate, and a frustum groove is formed on the guide tube. The taper of the frustum is adapted to the taper of the frustum groove. The base plate rises so that the end of the frustum moves away from the bottom of the frustum groove. After the base plate rises to its position, the bottom of the frustum is located in the frustum groove.

[0018] In one embodiment of this utility model, the spring buffer assembly 203 includes two air springs symmetrically arranged on both sides of the guide tube. The lower end of the air spring is connected to the support plate, and the upper end of the air spring is connected to the buffer plate. The air spring is used to support the buffer plate to support the base plate.

[0019] In one embodiment of this utility model, the four sets of buffer plates are located at the four corners of the base plate, the base plate lifting mechanism is located in the middle of the buffer plate near the crossbeam, and the lower end face of the base plate is provided with a number of long strip-shaped reinforcing ribs, the length direction of the reinforcing ribs being perpendicular to the length direction of the crossbeam.

[0020] The beneficial effects of adopting the above technical solution are as follows:

[0021] This application features four sets of support seats distributed at the four corners of two crossbeams. Each support seat includes a buffer plate and a support plate arranged opposite each other. The buffer plate is connected to the support plate via a spring buffer assembly. During vehicle operation, the spring buffer assembly can buffer and protect the base plate set on the four sets of buffer plates.

[0022] The substrate and crossbeam of this application are provided with a lifting drive mechanism, which can be used to drive the substrate to descend or to reset and rise under the support of the spring buffer assembly. After descending, the substrate is horizontally limited by the cooperation of the frustum on the buffer plate and the frustum groove on the support plate, thereby achieving the positioning of the substrate. This avoids the problem of horizontal movement of the substrate relative to the crossbeam caused by the setting of the spring buffer assembly, and increases the consistency of multiple remote sensing mappings.

[0033] 600 LiDAR device. Detailed Implementation

[0034] To make the objectives, technical solutions and advantages of this utility model clearer, the utility model will be clearly and completely described below in conjunction with specific embodiments.

[0035] like Figures 1 to 5 The remote sensing mapping and positioning device shown includes:

[0036] The roof frame 100 includes two parallel and symmetrical crossbeams 101;

[0037] Two sets of support components are respectively disposed on the two crossbeams 101. Each support component includes two spaced-apart support seats 200. Each support seat 200 includes a first clamping assembly detachably disposed on the crossbeam 101, a support plate 201-3 disposed on the first clamping assembly, a spring buffer assembly 203 disposed on the support plate 201-3, and a buffer plate 205 disposed on the spring buffer assembly 203.

[0038] The substrate 400 is disposed on the four sets of buffer plates 205 and is used to install and fix remote sensing equipment. In this embodiment, a lidar device 600 is shown in the illustration.

[0039] Two sets of substrate lifting mechanisms are symmetrically arranged on both sides of the substrate 400 to control the lifting of the substrate 400. A frustum groove 204-1 is provided on the support plate 201-3, and a frustum 206 is provided on the buffer plate 205 corresponding to the frustum groove 204-1. When the substrate 400 descends, the frustum 206 descends to engage with the frustum groove 204-1, thereby positioning the horizontal position of the substrate 400 after it has descended.

[0040] See Figure 4 and Figure 5 The substrate lifting mechanism includes a lifting fixed seat 300 located between the two support seats 200 and an electric cylinder 500 disposed on the substrate 400.

[0041] See Figure 4 and Figure 5The lifting and fixing base 300 includes two second clamping assemblies spaced apart on the crossbeam 101 and a fixing plate 303 disposed on the two second clamping assemblies. The fixing plate 303 has a fixing plate through hole 303-1. The end of the output rod 501 of the electric cylinder 500 passes through the base plate 400 and the fixing plate through hole 303-1 and is connected to a limiting plate 502. The two electric cylinders 500 of the two base plate lifting mechanisms synchronously drive the output rod 501 to retract, causing the limiting plate 502 to press against the fixing plate 303, thereby causing the base plate 400 to press against the spring buffer assembly 203 and descend towards the fixing plate 303. When the output rod 501 extends, the base plate 400 rises and resets under the drive of the spring buffer assembly 203, while the limiting plate 502 limits the upward displacement of the base plate 400.

[0042] See Figure 4 and Figure 5 The size of the limiting plate 502 is larger than the size of the through hole 303-1 of the fixing plate, and the size of the through hole 303-1 of the fixing plate is larger than the size of the output rod 501, so that the output rod 501 can move horizontally relative to the through hole 303-1 within the hole of the fixing plate. The side wall of the output rod 501 abuts against the edge of the through hole of the fixing plate, which can limit the relative displacement of the base plate 400 during vehicle movement and reduce the horizontal load on the spring buffer assembly 203.

[0043] See Figure 4 and Figure 5 The first clamping assembly includes a first supporting clamping body 201 and a second supporting clamping body 202. The first supporting clamping body 201 includes a first clamping body bend 201-1 and a first clamping body vertical part 201-2 disposed on the first clamping body bend 201-1. The shape and size of the cross-section of the first clamping body bend 201-1 correspond to the shape and size of the cross-section of one side of the crossbeam 101. The supporting plate 201-3 is disposed on the first clamping body vertical part 201-2.

[0044] The second support clamp 202 includes a second clamp bend 202-1 and a second clamp vertical part 202-2 disposed on the second clamp bend 202-1. The shape and size of the cross section of the second clamp bend 202-1 correspond to the shape and size of the cross section on the other side of the crossbeam 101.

[0045] The first clamping body vertical part 201-2 and the second clamping body vertical part 202-2 are respectively connected by bolt assemblies so that the first clamping body vertical part 201-2 and the second clamping body bent part 202-1 are clamped and fixed on the crossbeam 101.

[0046] See Figure 4 and Figure 5The second clamping assembly includes a third supporting clamp 301 and a fourth clamp 302. The cross-section of the third supporting clamp 301 is identical in shape and size to the cross-section of the first supporting clamp 201, and the cross-section of the fourth clamp 302 is identical in shape and size to the cross-section of the second supporting clamp 202. The third supporting clamp 301 and the fourth clamp 302 are clamped and fixed to the crossbeam 101 by a through bolt assembly.

[0047] See Figure 4 and Figure 5 A guide tube 204 is centrally located on the support plate 201-3. A frustum groove 204-1 is formed on the guide tube 204. The taper of the frustum 206 matches the taper of the frustum groove 204-1. When the base plate 400 rises, the end of the frustum 206 moves away from the bottom of the frustum groove 204-1. After the base plate 400 rises to its position, the bottom of the frustum 206 is located inside the frustum groove 204-1, preventing the frustum 206 from detaching from the frustum groove 204-1 and causing derailment.

[0048] The spring buffer assembly 203 includes two air springs symmetrically arranged on both sides of the guide tube 204. The lower end of the air spring is connected to the support plate 201-3, and the upper end of the air spring is connected to the buffer plate 205. The air spring is used to support the buffer plate 205 to support the base plate 400.

[0049] See Figures 1 to 3 The four sets of buffer plates 205 are located at the four corners of the base plate 400. The base plate lifting mechanism is located in the middle of the buffer plate 205 near the crossbeam 101. The lower end surface of the base plate 400 is provided with a number of long strip-shaped reinforcing ribs 400-1. The length direction of the reinforcing ribs 400-1 is perpendicular to the length direction of the crossbeam 101 to increase the strength of the base plate 400.

[0050] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
