With the development of modern society, the automobile conservation amount is increasing year by year. Orderly parking of automobiles is a ring that needs to be considered in the use process of automobiles. In many application environments, such as a market parking space, a stereoscopic parking space, an intelligent parking space, a car washing parking space, a user needs to drive a vehicle into the parking space correctly, and after the vehicle enters the parking space, the vehicle can be subjected to subsequent execution actions, such as shifting, position correction and the like by means of a parking transfer robot.

And different ground clearance exists for different kinds of vehicles. When a vehicle with an excessively small ground clearance enters a parking space, a chassis may be damaged by subsequent operation equipment, for example, a transfer robot collides with the chassis during operation.

In order to protect a vehicle with a chassis under the ground, the prior art often relies on a chassis detection device to detect the chassis height of the vehicle. The height detection device often comprises two important parts, namely an abutting part and a detection part, when the abutting part is touched by the chassis of the vehicle, the height detection device passively moves, and the detection part detects the movement of the abutting part and triggers a signal.

For example, chinese patent document CN216049753U discloses a spring hinge reset type vehicle chassis detection device, wherein the detection part is a sensor, the abutting part is a baffle, the baffle moves after being touched by the vehicle chassis, and the moving motion is captured by the sensor.

However, this solution has certain technical drawbacks, on the one hand, the baffle has limited contact dimensions, and different vehicle chassis widths, and different chassis positions and heights may be wrong in the case of missing detection errors. On the other hand, the baffle itself is a hard material part, and when the rotating part of the baffle breaks down and is blocked, the baffle can not move smoothly, and the baffle itself can damage the chassis of the vehicle.

Detailed Description

The present utility model will be described in further detail with reference to the accompanying drawings.

The present embodiment is only for explanation of the present utility model and is not to be construed as limiting the present utility model, and modifications to the present embodiment, which may not creatively contribute to the present utility model as required by those skilled in the art after reading the present specification, are all protected by patent laws within the scope of claims of the present utility model.

Embodiment 1, a vehicle chassis detection device includes a swing assembly 2. As shown in fig. 2 and 4, comprises a base plate 21, which can be mounted on the ground by means of common fixing elements, considered as a stationary element. A turning device 22 is mounted on the upper surface of the base plate 21. The rotating device 22 may adopt a hinge structure, which includes a rotating shaft 222, a turning plate 221 connected with the rotating shaft 222, and the upper surface of the turning plate 221 is connected with the swing arm 26, so that the swing arm 26 can turn around the rotating shaft 222. The outer ring of the rotating shaft 222 is sleeved with a torsion spring 223, so that elastic buffering exists for rotation and reset of the swing arm 26. The number of the rotating devices 22 can be adjusted by the user, in this case two, and are arranged in the length direction of the bottom plate 21, i.e. in the axial direction of the long shaft 24.

As shown in fig. 3, the swing arm 26 includes two parts, a main arm 261 and a side arm 262 connected thereto, which are vertically connected in this embodiment. The two side connecting arms 262 are provided with connecting shaft holes 263, and the long shaft 24 passes through the connecting shaft holes 263.

The roller 25 passes through the long axis 24. In this embodiment, the roller 25 is of a segmented design, comprising a plurality of short cylinders independent of each other. The sectional design reduces manufacturing cost on the one hand, and on the other hand avoids low fault tolerance rate caused by coaxiality requirements, and is convenient to assemble, and in addition, the sectional design also enables the rotation of the roller 25 to be smoother and more convenient.

In this case, the drum 25 includes two regions, i.e., a main drum 251 between two side arms 262 and a side extension drum 252 at an outer region of the side arms 262, as shown in fig. 3.

When the vehicle passes by, the chassis of the vehicle is too low and can touch the roller 25, so as to drive the swing arm 26 to rotate. This rotation is detected by the detection means 3 mounted on the base plate 21, triggering a signal.

In the scheme, on one hand, due to the existence of the side expansion cylinder, the width distance of the side expansion cylinder, which is contacted with the chassis of the vehicle, is increased, and the risk of false detection is reduced. On the other hand, the vehicle chassis is contacted with the roller 25, the circular shape and autorotation of the roller 25 can enable the contact to be flexible, and the vehicle chassis is protected to a certain extent.

In this embodiment, the hole diameter of the shaft hole of the roller 25 is larger than the radial diameter of the long shaft 24, so that the roller 25 is loosely sleeved on the long shaft 24. When the vehicle chassis touches the drum 25, the drum 25 rotates relative to the long axis 24. The long shaft 24 can be fixedly connected with the swing arm 26, i.e. the roller 25 rotates during rolling, and the long shaft 24 does not rotate. Since the long shaft 24 and the swing arm 26 are often made of metal materials, and the roller 25 is made of soft materials, such arrangement can avoid abrasion and noise generated during rotation of the two metal materials.

As shown in fig. 3 and 4, the detection device 3 is mounted on the base plate 21. And the sensing member 23 is mounted on the main arm 261 to cooperate with the detecting device 3. The detection device 3 can be of a contact type or a photoelectric type, and in the embodiment, a contact type travel switch is adopted, so that the detection effect is more stable and accurate. The sensing piece 23 can adjust the extension length, so that the starting angle of the swing arm 26 is adjusted to adapt to different detection heights. In this embodiment, the sensing member 23 may be a bolt, and the adjustment of the extension length is achieved by a threaded connection with the swing arm 26.
