[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by technicians in the technical field of this application; the terms used in the specification of the application herein are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned drawings are intended to cover non-exclusive inclusions. The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0031] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0035] The pressure-sensing knocking device 200 comprises a mounting seat 210, a sliding sleeve 220 and a pressure ball 230. The sliding sleeve 220 is nested in the mounting seat 210. An elastic pressure component 240 and a spring 250 are arranged between the mounting seat 210 and the sliding sleeve 220.

The pressure ball 230 is supported on the road surface by the sliding sleeve 220 under the action of the elastic pressure component 240 and the spring 250.

[0036] When cracks appear on the road surface, the elastic pressure component 240 and the spring 250 will push the pressure ball 230 into the road surface. The pressure value set on the elastic pressure component 240 will become smaller due to the reset of the spring 250. When the pressure data is detected to be smaller, it means that a crack appears on the ground. The device will actively move the crack depth detection mechanism 400 to the area where the pressure change is measured to detect the crack depth.

[0037] In the present application, the vehicle body structure 100 mainly adopts the driving principle of an electric four-wheel vehicle, the vehicle body 120 is provided with batteries and electric motors, and the wheels 110 are driven by the electric motors to move, and the corresponding internal brake electronic control structures are all prior art, which will not be described here, and the crack depth detection mechanism 400 is composed of a crack depth detection device and an electric push rod in the prior art.

[0042] A guide ring 213, wherein the guide ring 213 is used to arrange the end surface of the mounting plate 211 away from the vehicle body 120;

The outer wall of the guide ring 213 is provided with a guide slide groove adapted thereto, and the guide slide slides in the guide slide groove to ensure stability during the operation of the equipment;

[0045] In this embodiment, one end of the spring 250 is nested in the circumference of the elastic pressure component 240, and the other end is inserted into the inside of the push groove 222 and abuts against the annular seat provided inside the push groove 222; the sliding sleeve 220 is elastically connected to the mounting seat 210 through the elastic pressure component 240 and the spring 250;

[0046] As a preferred implementation in this embodiment, the elastic pressure assembly 240 includes a main rod 241, a pressure ring 242, an annular pressure sensor 243 and a gasket 244;

The compressed state of the spring 250 will also reduce the pressure on the annular pressure sensor 243 as the elastic force is released. The annular pressure sensor 243 detects the change in the compressed state of the spring 250 during the movement, thereby sensing the existence of the crack.
