DETAILED DESCRIPTION

[0021] The specific implementation modes of the present invention are described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific implementation modes.

[0022] Unless explicitly stated otherwise, throughout the specification and claims, the term “comprise” or variations such as “include” or “comprising”, etc., will be understood to include the stated elements or components but not to exclude other elements or components.

[0023] A resilient arm, such as Figure 1 As shown, it includes: a distance measuring wheel connecting mechanism 1, one end of which is connected to a distance measuring wheel 4 and an encoder 5; a device connecting mechanism 2, one end of which is connected to a detection device 6; an elastic connecting mechanism 3, including a first mechanism and a second mechanism, one end of the first mechanism can be rotatably connected and fixedly connected to the other end of the distance measuring wheel connecting mechanism 2, one end of the second mechanism is rotatably connected to the other end of the first mechanism, and the other end of the second mechanism is fixedly connected to the other end of the device connecting mechanism 1.

[0024] Specifically, when the elastic connection mechanism 3 is installed with the distance measuring wheel 4 and the device connection mechanism 2, the bottom of the distance measuring wheel 4 can just touch the road surface. When measuring, the orientation of the detection device 6 and the distance measuring wheel 4 is changed according to the angle of the measured road surface to ensure that the bottom of the detection device 6 and the bottom of the distance measuring wheel 4 can always touch the measuring surface.

[0025] As an optional implementation, the distance measuring wheel connection mechanism includes a first mounting member 11, the first mounting member 11 includes a first through hole 111 and a plurality of second through holes 112 surrounding the first through hole, and the first mounting member 11 is used to mount the distance measuring wheel 4 and the encoder 5.

[0026] Specifically, the distance measuring wheel 4 can be mounted on the first mounting member 11 and rotate freely. The second through hole 112 can cooperate with a screw to fix the encoder 5. The encoder 5 has a rotating shaft, and the rotating shaft can pass through the first through hole 111 and be connected to the distance measuring wheel 4, that is, the distance measuring wheel 4 is fixed to the distance measuring wheel connecting mechanism 1 through the encoder 5.

[0027] As an optional implementation, the device connecting mechanism 2 includes a second mounting member 21 , the second mounting member includes a third through hole 211 , and the second mounting member 21 is used to mount the device connecting mechanism 2 on the detection device 6 .

[0028] Specifically, there are multiple third through holes 211, and the third through holes can be matched with screws to install the device connection mechanism 2 on the detection device. As a preferred embodiment, the device connection mechanism 2 includes a first panel for connecting the elastic connection mechanism 3, the first panel is perpendicular to the horizontal direction, and the elastic connection mechanism 3 is perpendicular to the first panel.

[0029] As an optional implementation, the first mechanism includes a swing plate 31 and a first connecting member 32 , and the swing plate 31 and the distance measuring wheel connecting mechanism 1 are rotatably connected and locked via the first connecting member 32 .

[0030] Specifically, the first connecting member 32 can realize two states of rotation and locking of the swing plate 31 and the distance measuring wheel connecting mechanism 1. When locked, the relative position of the swing plate 31 and the distance measuring wheel connecting mechanism 1 is fixed, which can adapt to the measurement of the top surface and the bottom surface. When rotating, the relative position of the swing plate 31 and the distance measuring wheel connecting mechanism 1 can be changed, which can adapt to the measurement of potholes and complex roads.

[0031] As an optional embodiment, the second mechanism includes an articulated seat 33, a second connecting member 34, and a third connecting member 35, the swing plate 31 is rotatably connected to the articulated seat 33 via the second connecting member 34, and the articulated seat 33 is fixedly connected to the equipment connecting mechanism 2 via the third connecting member 34.

[0032] The second connecting member 34 has a torsional force, which can make the swing plate 31 rotate when subjected to force, and can make the swing plate 31 rebound when not subjected to force.

[0033] As an optional embodiment, the first connecting member 32 includes a screw 321 that rotatably connects the swing plate 31 and the measuring wheel connecting mechanism 1, and a quick-release pin 322 that detachably connects the swing plate 31 and the measuring wheel connecting mechanism 1, and a fourth through hole for installing the screw 321 and the quick-release pin 322 is provided on the swing plate 31, and a fifth through hole for installing the screw 321 and the quick-release pin 322 is provided on the measuring wheel connecting mechanism 1.

[0034] Specifically, the quick-release pin 322 can be quickly disassembled and fixed. When the quick-release pin 322 is fixed, the swing plate 31 and the distance measuring wheel connecting mechanism 1 are fixed by the quick-release pin 322 and the screw 321 at the same time, and the two are relatively unchanged, which is equivalent to a rigid connection. Figure 2 As shown, when the quick plug 322 is pulled out, the first connecting member 32 fixes the swing plate 31 and the distance measuring wheel connecting mechanism 1 only through the rotatable screw 321, which is equivalent to an elastic connection. At this time, the distance measuring wheel 4 contacts the ground under the action of gravity. At this time, as the ground conditions change, the rotation of the screw 321 can make the center of gravity of the distance measuring wheel 4 automatically adjust according to the road conditions, so that the distance measuring wheel 4 can fit the ground in real time, thereby making the distance measurement of the present application applicable to horizontal roads, especially complex sandy soft roads and potholes.

[0035] As an optional embodiment, the second connecting member 34 includes a rotating shaft 341 and a torsion spring 342 arranged outside the rotating shaft 341, the swing plate 31 is provided with a sixth through hole for installing the rotating shaft 341, and the hinge seat 33 is provided with a seventh through hole for installing the rotating shaft 341.

[0036] Specifically, Figure 3 As shown, when the quick latch 322 is inserted, the first connecting member 32 rigidly connects the swing plate 31 and the distance measuring wheel connecting mechanism 1. At this time, the distance measuring wheel 4 can just touch the contact measurement surface under the elastic force of the torsion spring 342. At this time, the elastic distance measuring device of the present application can adapt to the measurement of the top surface and the side surface. Due to the existence of the torsion force of the torsion spring 342, the elastic connecting mechanism 3 can connect distance measuring wheels 4 of different radii, as long as the radius of the distance measuring wheel 4 is greater than or equal to the distance from the center of the rotating shaft 341 to the bottom surface. The distance measuring wheel 4 with a radius greater than the distance from the center of the rotating shaft 341 to the bottom surface can still keep the bottom surface flush with the distance measuring device under the torsion force of the torsion spring 342.

[0037] As an optional embodiment, the third connecting member 35 includes a plurality of screws 351 , the hinge seat 33 is provided with an eighth through hole for installing the screws 351 , and the device connecting mechanism 2 is provided with a ninth through hole for installing the screws 351 .

[0038] Specifically, there are a plurality of the eighth through holes, and the number of the eighth through holes corresponds to the number of the screws 351 , and the ninth through holes are a plurality of through holes, the number of which corresponds to the eighth through holes and the screws 351 .

[0039] An elastic distance measuring device, such as Figure 2-4 As shown, it includes any one of the elastic connection mechanisms 3 mentioned above, a distance measuring wheel 4, an encoder 5, and a detection device 6.

[0040] Specifically, the elastic distance measuring device can adapt to complex environments and ensure that the distance measuring wheel 4 is in real-time contact with the ground. As a preferred embodiment, the encoder 5 is electrically connected to the detection device 6, and the encoder 5 is located at the center of the distance measuring wheel 4 after installation to convert the displacement into an electrical signal and transmit it to the detection device 6.

[0041] By adopting the above technical solution, an elastic connection mechanism 3 and an elastic distance measuring device are provided, wherein a first connection member 32 having a quick-release pin 322 and a screw 321, and a second connection member 34 having a rotating shaft 341 and a torsion spring 342 are provided. When the quick-release pin 322 is inserted, the first connection member 32 makes the swing plate 31 and the distance measuring wheel connection mechanism 1 relatively fixed, which can adapt to the measurement of the top surface and the wall surface. When the quick-release pin 322 is removed, the first connection member 32 makes the swing plate 31 and the distance measuring wheel connection mechanism 1 only rotatably connected by the screw 321, and the center of gravity of the distance measuring wheel 4 can be automatically adjusted according to the shape of the road surface, so that the distance measuring wheel 4 is in real-time contact with the ground, so as to adapt to the road surface with complex terrain, and can complete the distance measurement work of the wall surface and the top surface.
