Description

Technical Field

[0001] The utility model relates to the technical field of three-dimensional garages, and particularly relates to an automobile chassis detection mechanism. Background Art

[0002] When an existing three-dimensional garage stores a vehicle, in order to facilitate the successful storage of the vehicle, a clamping transporter is usually used to enter under the chassis of the vehicle to carry the vehicle, and this method is relatively convenient. However, the clamping transporter has a certain height. When the vehicle chassis is too low, the clamping transporter cannot smoothly enter under the vehicle chassis. In order to avoid the clamping transporter from colliding with the vehicle chassis, it is necessary to detect the height of the vehicle chassis.

[0003] The existing scheme usually uses a trigger structure of a spring piece to detect the vehicle chassis. Due to the insufficient rigidity of the spring piece, irreversible deformation is likely to occur after long-term use or when the force is large, thus affecting the detection of the vehicle chassis.

[0004] Therefore, a new scheme is needed to improve the service life of the vehicle chassis detection mechanism. Summary of the Utility Model

Specific embodiments

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

[0034] As Figures 1 to 8 shown, this embodiment proposes an automobile chassis detection mechanism, including:

[0035] A mounting box 11, which has an accommodating chamber 12, and an opening 13 communicating with the accommodating chamber 12 is provided on the top surface of the mounting box 11;

[0036] A button 14, which is arranged in the opening 13;

[0037] A pressing plate 15, which is installed in the accommodating chamber 12 through a rotating assembly 16, and the pressing plate 15 is used to press the button 14 downward;

[0038] An elastic reset component 17, which is hinged to the rotating shaft 18 of the rotating assembly 16 through a connecting piece 26.

[0039] The automobile chassis detection mechanism of this solution is used to detect the chassis height of an automobile. Before the vehicle enters the warehouse, the height of the vehicle chassis is detected to facilitate judging whether the vehicle can be transported by a clamping transporter.

[0040] Among them, the pressing plate 15 is used to detect the height of the vehicle chassis. When the height of the vehicle chassis is too low, after the pressing plate 15 is squeezed by the vehicle, it will push the button 14 downward. At this time, the chassis detection mechanism determines that the position of the vehicle chassis is too low and does not meet the requirements for entering the warehouse.

[0041] Furthermore, the button 14 is used to control the on / off of the circuit. Its working principle is the same as that of a microswitch. Regarding how the button 14 controls the circuit, it will not be elaborated in depth here.

[0042] Compared with the microswitch, the present application is provided with a rotating component 16 and an elastic reset component 17. Compared with only using the elastic sheet method, this solution has the advantages of high reset strength and good structural stability, and can significantly extend the service life of the device.

[0043] As an implementation manner of this embodiment, the rotating component 16 includes:

[0044] A support plate 19, and the support plate 19 is fixed on the inner wall of the accommodating chamber 12 through a mounting rod 20;

[0045] A bearing seat 21, the bearing seat 21 is installed in the mounting opening of the support plate 19, and a rotating shaft 18 is installed in the bearing seat 21;

[0046] A swing plate 22, the swing plate 22 is fixed on the rotating shaft 18, and a pressing plate 15 is fixed at the upper end of the swing plate 22.

[0047] The swing plate 22 in this solution is in a suspended state, and the movement of the swing plate 22 is controlled by the rotating shaft 18. By setting the rotating component 16 in this solution, the purpose that the pressing plate 15 can rotate is achieved. The pressing plate 15 in this solution can adopt a rigid plate, so as to effectively avoid plastic deformation of the pressing plate 15. It is used to improve the structural strength and service life of the pressing plate 15.

[0048] As an implementation manner of this embodiment, the elastic reset component 17 includes:

[0049] A sleeve 23, the sleeve 23 has an inner hole, and a vent hole 24 communicating with the inner hole is provided on the circumferential surface of the sleeve 23. One end of the sleeve 23 away from the connecting piece 26 is installed on the inner wall of the accommodating chamber 12 through a hinge seat 25;

[0050] A piston rod 27, the piston part 28 of the piston rod 27 is installed in the inner hole through a spring 30, and the rod part 29 of the piston rod 27 is hinged to the connecting piece 26.

[0051] Furthermore, the inner hole of the sleeve 23 is a blind hole, and an end cover is hermetically arranged at the entrance end of the inner hole. A guiding hole for slidably mounting the rod part 29 is provided on the end cover. Springs 30 are respectively arranged at both ends of the piston part 28.

[0052] Since the spring 30 is not easily fixed in the inner hole of the sleeve 23, if a single spring 30 is used, it is necessary to weld and fix both ends of the spring 30, and this operation method is difficult. Springs 30 are respectively arranged at both ends of the piston part 28 in this solution. After the end cover on the sleeve 23 welds and seals the inlet end of the inner hole, the two springs 30 can apply elastic force to the piston part 28. In this state, the pressing plate 15 and the button 14 are in a separated state. When the vehicle chassis presses on the pressing plate 15, the pressing plate 15 rotates, and at the same time the spring 30 undergoes elastic deformation. After the vehicle chassis separates from the pressing plate 15, when the spring 30 resets to the initial state, at this time the pressing plate 15 and the button 14 are separated.

[0053] Furthermore, the pressing plate 15 has a transverse portion 31 and a vertical portion 32. The lower end of the vertical portion 32 is fixed to the upper end of the swing plate 22, and the transverse portion 31 is arranged at the upper end of the vertical portion 32. As an implementation manner of this embodiment, a pressing wheel 33 is installed at one end of the transverse portion 31 away from the vertical portion 32, and the pressing wheel 33 is located above the transverse portion 31. This solution acts through the pressing wheel 33 and the vehicle chassis, which is used to reduce the friction between the pressing wheel 33 and the vehicle chassis and avoid scratches on the vehicle chassis.

[0054] Furthermore, the vehicle chassis detection mechanism in this solution is installed at the entrance of the parking lot. By opening an installation groove on the ground, it is used to install the installation box 11. Further, the lower surface of the installation box 11 is provided with a height adjustment member, and at this time it is convenient to adjust the height of the pressing wheel 33 on the pressing plate 15. Or the lower surface of the installation box 11 is elastically installed in the installation groove. When the chassis of the vehicle is extremely low, it is used to prevent the installation box 11 itself from having rigid friction with the vehicle chassis.

[0055] For those of ordinary skill in the art, without departing from the inventive concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model.
