Embodiment 1

[0042] The embodiment of the present application discloses an active suspension mechanism, such as figure 1 As shown, the active suspension mechanism includes a fixed chassis 2 and a pressing device 2 for pressing down the fixed chassis 2, wherein one end of the fixed chassis 2 is used to connect with the steering wheel 4 of the AGV trolley, and the other end of the fixed chassis 2 is used to connect with the steering wheel 4 of the AGV trolley. The spring shock absorber 5 of the AGV trolley is connected. In this way, the downward pressure of the end of the fixed chassis 2 connected to the spring shock absorber 5 is controlled by the downward pressure applied by the downward pressure device 2 to the fixed chassis 2, and the spring shock absorber 5 stiffness and resistance (especially rebound resistance) is controlled by the downforce exerted by the fixed chassis 2. On the other hand, the friction between the steering wheel 4 of the AGV trolley and the ground is also controlled...

Embodiment 2

[0067] The embodiment of the present application discloses an AGV trolley. The AGV trolley includes a steering wheel 4, a spring shock absorber 5 and an active suspension mechanism, wherein the active suspension mechanism is an active suspension mechanism according to the embodiment of the present application.

[0068] In the embodiment of this application, as figure 1 , figure 2 , image 3 As shown, the AGV trolley includes a left steering wheel 41 and a right steering wheel 42, and the left steering wheel 41 and the right steering wheel 42 are all located on the outside of the swing device 21. In this way, when the swing device 21 is pressed down, the left steering wheel 41 and the right steering wheel 42 do not It will be lower than the swing device 21, thereby reducing the probability of the left steering wheel 41 and the right steering wheel 42 being stuck.

[0069] In the embodiment of the present application, the AGV trolley also includes a second drive motor 7, wher...

Abstract

The invention discloses an active suspension mechanism, an AGV comprising the active suspension mechanism and an AGV control method, and the active suspension mechanism comprises a fixed chassis and apressing device; one end of the fixed chassis is used for being connected with a steering wheel of the AGV, and the other end of the fixed chassis is used for being connected with the spring shock absorber of the AGV. The pressing device comprises a detection piece, a control piece, a driving device and a pressing piece; the detection piece is electrically connected with the control piece, and the detection piece is used for detecting road conditions and inputting road condition information to the control piece; the control piece is further electrically connected with the driving device and used for sending a driving signal to the driving device according to the road condition information; the driving device abuts against the fixed chassis through the pressing piece and is used for driving the pressing piece to extrude the fixed chassis according to the driving signal. The rigidity and the resistance of the spring shock absorber of the AGV can be adjusted according to the road sectioncharacteristics, so that the AGV can run more stably.

Description

technical field [0001] The present application relates to the technical field of AGV trolleys, in particular, to an active suspension mechanism, an AGV trolley including the above-mentioned active suspension mechanism, and an AGV trolley control method. Background technique [0002] At present, automatic guided vehicles (AGV, Automat i c Gui ded Veh i c le) are often used in factories (regular and flat terrain). However, during use, the AGV car is easy to roll over and overturn, especially when driving on steep slopes and large potholes, the AGV car is easy to hang in the air, and it is very easy to roll over and overturn. Contents of the invention [0003] The purpose of the embodiment of the present application is to disclose an active suspension mechanism, an AGV trolley, and an AGV trolley control method, which are used to adjust the stiffness and resistance of the spring shock absorber of the AGV trolley according to the road condition information, thereby enabling th...
