Detailed Implementation

[0033] The technical solutions of this application will be further described below with reference to specific embodiments, but this application is not limited to these embodiments.

[0034] like Figures 1 to 8As shown, this embodiment proposes a portable surveying vehicle-mounted backpack. The backpack 11 is mounted on the rear seat 14 of a two-wheeled vehicle 13 via a fixing device 12. The fixing device 12 includes a bracket 15 and a clamping assembly 16. The bracket 15 has a first mounting arm 17 and a second mounting arm 18. The second mounting arm 18 is located at the lower end of the first mounting arm 17. The backpack 11 is mounted on the first mounting arm 17, and the second mounting arm 18 is mounted on the rear seat 14 via the clamping assembly 16.

[0035] The technical advantage of this solution is that it can effectively reduce the burden on the human body caused by the surveying backpack 11.

[0036] In the prior art, the carrying posture of a person carrying a surveying backpack 11 will change in different ways, thus affecting the accuracy. In this solution, the backpack 11 is installed on the rear seat 14 of a two-wheeled vehicle 13, and the position of the backpack 11 relative to the two-wheeled vehicle 13 is relatively fixed. Therefore, compared with the prior art, the surveying accuracy can be significantly improved.

[0037] Furthermore, the first mounting arm 17 is arranged vertically, and the second mounting arm 18 is arranged horizontally.

[0038] The bracket 15 in this design is a sheet metal structure, and is made of Q345 steel.

[0039] Furthermore, the backpack 11 is detachably mounted on the first mounting arm 17. In this solution, by removing the backpack 11, surveying can still be carried out manually, adapting to scenarios where two-wheeled vehicles cannot pass in complex environments.

[0040] Furthermore, the first mounting arm 17 is provided with mounting holes for mounting the backpack 11. The backpack 11 is connected to the first mounting arm 17 by a bolt assembly.

[0041] Furthermore, backpack 11 is equipped with shoulder straps 47.

[0042] In one embodiment of this invention, the clamping component 16 includes:

[0043] The clamping element 19 is provided in two sets, connected by a width adjusting element 20. The two sets of clamping elements 19 are located on opposite sides of the rear seat 14 in the width direction, and are used to clamp the rear seat 14. The clamping elements 19 are connected to the second mounting arm 18 by bolts 21. In this design, the clamping elements 19 can be adjusted in size along the X-axis. Furthermore, the width adjusting element 20 is a width adjusting bolt.

[0044] The lower locking block 22 is installed below the locking member 19 via a height adjustment member 23. The lower locking block 22 has a horizontal abutment surface 24, which is used to press the rear seat 14 upward. The lower locking block 22 in this solution can be adjusted in size along the Z direction.

[0045] The clamping component 16 in this solution is made of aluminum alloy, and more specifically, 6061 aluminum alloy.

[0046] This solution proposes a specific structure for the clamping component 16.

[0047] Furthermore, each set of clamping components 19 has two upper clamping blocks, which are fixed by a connecting plate. The connecting plate is connected to the second mounting arm 18 by bolts 21.

[0048] Furthermore, the height adjustment component 23 is a height adjustment screw, and each lower locking block 22 is installed below the upper locking block via the height adjustment screw.

[0049] Furthermore, the upper and lower locking blocks 22 are L-shaped and are used to fit two adjacent surfaces of the rear seat 14.

[0050] In one embodiment of this invention, the second mounting arm 18 is provided with a slotted hole 25 for mounting the bolt 21. The slotted hole 25 in this design serves to accommodate the distance adjustment between the two sets of clamping members 19.

[0051] In one embodiment of this invention, the backpack 11 is equipped with a sensor assembly. The sensor assembly includes a main lidar 42, a blind spot radar 43, five panoramic cameras 44, and three surround-view cameras 45. Furthermore, the backpack 11 is also equipped with a power supply 38.

[0052] The backpack weighs approximately 8kg and measures 310mm x 174mm x 866mm (width x thickness x height). When folded in half, its maximum height is 476mm.

[0053] In addition, this application also proposes a surveying device including the above-mentioned portable surveying vehicle backpack, and further includes a speed measuring device 26. The speed measuring device 26 includes a speed measuring module 27 and an installation module 28. The speed measuring module 27 is used to detect the driving speed of the two-wheeled vehicle 13. The speed measuring module 27 is installed on the two-wheeled vehicle 13 through the installation module 28.

[0054] Furthermore, the speed measuring module 27 includes a speed measuring wheel 29 and a speed encoder 30. The circumferential surface of the speed measuring wheel 29 contacts the circumferential surface of the front wheel 31 of the two-wheeled vehicle 13, and the speed measuring wheel 29 rotates with the front wheel 31. The speed measuring wheel 29 is coaxially connected to the detection shaft of the speed encoder 30 via a mounting shaft 32. There are two speed measuring wheels 29.

[0055] The speed encoder 30 is used to measure the driving speed. The speed encoder 30 is existing technology. The structure and working principle of the speed encoder 30 can be referred to the existing technology. It will not be described in detail in this solution.

[0056] Furthermore, the installation module 28 includes:

[0057] The frame has sidewalls 33 and transverse arms 34. The two ends of the transverse arms 34 are respectively fixed with sidewalls 33. One sidewall 33 is used to install the speed encoder 30, and the other sidewall 33 is used to rotatably install the mounting shaft 32. The transverse arms 34 are hinged to the end of the mudguard 35 of the front wheel 31 of the two-wheeled vehicle 13.

[0058] An elastic element, one end of which is mounted on the side wall 33, and the other end of which is mounted on the front fork 41 of the two-wheeled vehicle 13.

[0059] The technical effect of this solution is that by tightening the elastic element, the speed measuring wheel 29 can be effectively pressed against the circumference of the front wheel 31 of the two-wheeled vehicle 13, which facilitates the rotation of the speed measuring wheel 29.

[0060] Furthermore, the speed measuring device 26 also includes a limiting assembly, which includes a rotating part 36. Two sets of rotating parts 36 are respectively used to fit against both sides of the front wheel 31 of the two-wheeled vehicle 13, and the rotating parts 36 are mounted on the side wall 33 via a connector 37. The technical advantage of this solution is that it controls the distance between the side wall 33 and the side of the front wheel 31, effectively improving installation accuracy. The rotating parts 36 in this solution can rotate with the front wheel 31, reducing friction on the front wheel 31.

[0061] Furthermore, the rotating part 36 is a wheel or a double-bearing lifting ring.

[0062] Furthermore, the elastic element is a tension spring 39, one end of which is hinged to the side wall 33, and the other end of which is rotatably mounted on the front fork 41 of the two-wheeled vehicle 13 via a mounting seat 40. Furthermore, the mounting seat 40 is fitted onto the front fork 41. In this design, the two-wheeled vehicle 13 is a bicycle, electric bicycle, or motorcycle, where the front fork 41 is a technical term for a component of the two-wheeled vehicle 13, used to mount the axle on the front wheel 31.

[0063] like Figure 9 As shown, this application also proposes a surveying system that includes the above-mentioned surveying device, wherein the surveying system has a controller 46.

[0064] Furthermore, the controller 46 is a mobile controller 46, and a sensor-hub controller 46 is further adopted to build the entire power supply, control and feedback system.

[0065] The controller 46 in this solution is electrically connected to the sensor components, covering the information processing and integrated interaction of the radar, camera, driving distance, speed, positioning and remote control modules of the whole machine.

[0066] For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this invention, and these all fall within the protection scope of this invention.
