It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only and do not represent the only embodiments.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

In an embodiment, please refer to fig. 1 and fig. 2, the present invention provides a damping cab base for a reversible cab of a heavy-duty forklift, including: the frame comprises a frame base 3, a cab 2, an elastic shock absorber 1 and a cushion pad 4; the first end of the elastic shock absorber 1 is in contact with the cab 2, and the second end of the elastic shock absorber 1 is connected with the frame base 3, so that the cab 2 is supported on the frame base 3; the cushion pad 4 is disposed between the frame base 3 and the cab 2.

The utility model discloses technical scheme, driver's cabin 2 passes through elastic shock absorber 1 and sets up on frame base 3, realize supporting and shock attenuation effect, 3 set up blotter 4 between driver's cabin 2 and frame base simultaneously, when fork truck driving process, because acceleration and deceleration or ground are uneven and the driver's cabin 2 that leads to jolt the shake, the major part can be absorbed the buffering by elastic shock absorber 1, and blotter 4 can avoid driver's cabin 2 and frame base 3's direct contact, play the effect of supplementary buffering. The buffer effect that this technical scheme played is good, simple structure, and the cost is lower, does benefit to extensive popularization and application.

In this embodiment, the bottom of the cab 2 is pressed down on the first end of the elastic shock absorber 1, and the second end of the elastic shock absorber 1 is fixedly connected with the frame base 3. Since the cab 2 can be tilted forward, the cab 2 is simply pressed above the elastic shock absorbers 1, not fixedly connected together, and when the cab 2 needs to be tilted forward, the cab 2 is separated from the elastic shock absorbers 1.

Of course, the contact position of the elastic shock absorber 1 may be other, such as contact with a bump on the sidewall of the cab 2, and the like, as long as the support and the buffering of the cab 2 can be achieved, and is not limited to the description in the embodiment.

Wherein, the cushion pad 4 is arranged on the frame base 3 and is positioned right below the cab 2. It will be appreciated that the cushion 4 may also be provided at the bottom of the cab 2, at a position directly above the frame base 3. It only needs to play the role of buffering and avoiding friction, and is not limited to the description in this embodiment.

Referring to fig. 3, 4 and 5, in the present embodiment, the elastic damper 1 is a spring damper. Specifically, the spring damper comprises a spring 13, an elastic piece and a telescopic rod 11; one end of the telescopic rod 11 is fixed on the frame base 3, and the elastic piece is fixed at the other end of the telescopic rod 11; the elastic piece is abutted against the bottom of the cab 2; the spring 13 is sleeved outside the telescopic rod 11, and two ends of the spring are respectively abutted against the frame base 3 and the elastic member.

It should be noted that, since the cab 2 is tiltable forward, the elastic member is fixed on the spring 13, and the cab 2 is only pressed on the elastic member and is not fixedly connected. When the cab 2 needs to be tilted forward, the cab 2 is separated from the elastic member.

It should be noted that, when in use, the spring 13 cushions the cab 2 up and down, and the telescopic rod 11 only needs to move in a telescopic manner, and the elastic member also plays a good auxiliary buffering role.
