DETAILED DESCRIPTION

[0018] The present invention will be further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solutions of the present invention and are not intended to limit the protection scope of the present invention.

[0019] Example 1

[0020] like Figure 1 and Figure 2 As shown, the present invention discloses a rotary instrument panel device for a cab of an engineering machinery, including a rotary instrument panel assembly 1, which is a core main structure and builds a stable installation platform for key components such as a steering column, a brake pedal, an accelerator pedal, and a seat. The rotary instrument panel assembly 1 includes a rotary instrument panel support 16, on which a steering assembly 11 and a tractor seat 15 are arranged, a steering column is arranged in the steering assembly 11, and an accelerator pedal 13 and a brake pedal 14 are arranged on the steering assembly 11. An electric turntable 12 is arranged below the rotary instrument panel support 16, and the electric turntable 12 is located above the floor of the cab and is driven by a power motor to provide power for the rotation of the rotary instrument panel assembly 1.

[0021] The lower side of the rotating instrument panel support 16 is connected to the upper end of the connecting vertical rod 2, and the connecting vertical rod 2 passes through the through hole on the electric turntable 12 and is connected to the flexible transmission mechanism 3, which also builds a channel for the pipeline harness to enter the cab. The rotating instrument panel support 16 rotates to drive the flexible transmission mechanism 3 to rotate through the connecting vertical rod 2. The flexible transmission mechanism 3 is arranged under the cab and is used to place the pipeline harness led out of the rotating instrument panel assembly 1.

[0022] During the operation, the operator can easily and simply rotate the instrument panel assembly to the working angle required for observation according to personal use needs, thereby increasing the operator's field of view, improving the operator's operating safety, and improving the operator's operating efficiency. At the same time, when the flexible transmission mechanism rotates, the instrument panel assembly can rotate 180° forward and backward, creating a cavity environment with a protective function for the wiring harness, effectively ensuring that the pipeline wiring harness will not be squeezed and pulled during the rotation of the instrument panel, avoiding damage.

[0023] Example 2

[0024] The present invention discloses a rotary instrument panel device for a cab of an engineering machinery, including a rotary instrument panel assembly 1, which is a core main structure and constructs a stable installation platform for key components such as a steering column, a brake pedal, an accelerator pedal, and a seat. The rotary instrument panel assembly 1 includes a rotary instrument panel support 16, on which a steering assembly 11 and a tractor seat 15 are arranged, a steering column is arranged in the steering assembly 11, an accelerator pedal 13 and a brake pedal 14 are arranged on the steering assembly 11, and the steering assembly 1 is connected to the accelerator pedal 3 and the brake pedal 4 by bolts. An electric turntable 12 is arranged below the rotary instrument panel support 16, and the electric turntable 12 is located above the floor of the cab and is driven by a power motor to provide power for the rotation of the rotary instrument panel assembly 1.

[0025] The lower side of the rotating instrument panel support 16 is connected to the upper end of the connecting vertical rod 2, and the connecting vertical rod 2 passes through the through hole on the electric turntable 12 and is connected to the flexible transmission mechanism 3, which also builds a channel for the pipeline harness to enter the cab. The rotating instrument panel support 16 rotates to drive the flexible transmission mechanism 3 to rotate through the connecting vertical rod 2. The flexible transmission mechanism 3 is arranged under the cab and is used to place the pipeline harness led out of the rotating instrument panel assembly 1.

[0026] like Figure 3 As shown, the flexible transmission mechanism 3 includes a drag chain fixing platform 34, which is fixed under the cab through a bracket to provide a fixing platform for the drag chain 31. A drag chain rotating platform 36 and a drag chain 31 are provided on the drag chain fixing platform 34, and the drag chain rotating platform 36 rotates 180° in the forward and reverse directions on the drag chain fixing platform 34. The entrance position of the drag chain 31 is connected to the cab, and the exit position of the drag chain 31 is connected to the drag chain rotating platform 36. The drag chain 31 is used to place the pipeline harness led out of the rotating instrument panel assembly 1, and constructs a cavity environment with a protective function for the wiring harness pipelines of brakes, instruments, etc., to ensure that the pipeline harness will not be squeezed and pulled during the rotation of the instrument panel, thereby avoiding damage. In addition, the length of the drag chain 31 directly limits the angle at which the rotating instrument panel assembly 1 can rotate.

[0027] The drag chain rotating platform 36 is connected to the lower end of the connecting vertical rod 2 by bolts, and a rotating axis is provided for the drag chain 31 during the rotation of the rotating instrument panel assembly 1. When the power motor drives the rotating instrument panel assembly 1 to rotate, the drag chain 31 is driven to rotate through the drag chain rotating platform 36. The inner and outer sides of the drag chain fixed platform 34 are respectively provided with a drag chain counterclockwise limit plate 32 and a drag chain clockwise limit plate 33 for providing a limit for the movement of the drag chain 31. The drag chain counterclockwise limit plate 32 and the drag chain clockwise limit plate 33 are welded to the drag chain fixed platform 34. When the rotating instrument panel assembly 1 rotates counterclockwise to a set angle, the drag chain counterclockwise limit plate 32 provides a limit for the movement of the drag chain 31. When the rotating instrument panel assembly 1 rotates clockwise to a set angle, the drag chain clockwise limit plate 33 provides a limit for the movement of the drag chain 31 and provides protection for the drag chain in the Y direction. A drag chain rotation blocking plate 35 is provided on the drag chain rotation platform 36 at the rotation center of the drag chain 31 to provide a minimum winding radius for the drag chain and provide protection for the wire harness after it leaves the drag chain.

[0028] The installation method of the present invention is as follows: firstly, the brake pipeline, instrument harness and other pipelines are passed through the drag chain 31, and then the flexible transmission mechanism 3 is screwed with the connecting vertical rod 2 and installed at the bottom of the cab, and then the pipeline is passed through the electric turntable 12, and the line is divided in the rotating instrument panel support 16, and is respectively connected with the steering assembly 11, the accelerator pedal 13, the brake pedal 14 and the instrument, and finally the steering assembly 11, the accelerator pedal 13, the brake pedal 14 are screwed, and then they are installed on the rotating instrument panel support 16 with the tractor seat 15.

[0029] During the operation, the operator can easily rotate the instrument panel assembly to the working angle required for observation according to personal needs, thereby increasing the operator's field of view, improving the operator's operating safety, and improving the operator's operating efficiency. At the same time, when the flexible transmission mechanism rotates, the drag chain can slide freely, allowing the instrument panel assembly to rotate 180° forward and backward, creating a cavity environment with protective functions for the wiring harness, effectively ensuring that the pipeline wiring harness will not be squeezed and pulled during the rotation of the instrument panel, avoiding damage.

[0030] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
