In a preferred embodiment, referring to fig. 3 to 6, the movable hand brake valve structure further comprises a wire takeup device 5, the hand brake valve body 4 is provided with a breather hose 41, and the wire takeup device 5 is used for taking up and paying out the breather hose 41 according to the position of the hand brake valve body 4.

Specifically, the air hose 41 passes through the cab 1 and is communicated with the parking control system of the vehicle, and meanwhile, the air hose 41 is wound on the wire winding device 5, so that the wire winding device 5 is enabled to wind and unwind the air hose 41 along with the position of the hand brake valve body 4, the situation that the air hose 41 is interfered with other parts is avoided, the regularity in the cab 1 is improved, the safety of the movable hand brake valve structure is improved, and the use experience of a driver is further improved.

The application does not limit the setting position of the wire collector 5 specifically, and preferably, the wire collector 5 is arranged at the end part of the guide rail 2, namely, the wire collector 5 is arranged at one side of the supporting section 23, so that the space at one side of the supporting section 23 is reasonably utilized, and the condition that the wire collector 5 and other components interfere with each other is avoided. In other embodiments, the wire takeup device 5 may also be disposed on the sliding seat 3, so that the wire takeup device 5 moves synchronously with the sliding seat 3.

The application can be realized by adopting or referring to the prior art at the places which are not described in the application.

In this specification, each embodiment is described in a progressive manner, and identical and similar parts of each embodiment are all referred to each other, and each embodiment mainly describes differences from other embodiments.

The foregoing is merely exemplary of the present application and is not intended to limit the present application. Various modifications and variations of the present application will be apparent to those skilled in the art. Any modification, equivalent replacement, improvement, etc. which come within the spirit and principles of the application are to be included in the scope of the claims of the present application.
