Berth device with self-locking function

Abstract

The invention relates to a berth device with a self-locking function. The berth device comprises a left bracket, a right bracket, a rear sleeve, a left connecting pipe, a right connecting pipe, and an upper berth assembly, wherein the left bracket and the right bracket are respectively fixed to cab panel beatings on the left side and the right side of a cab; the rear sleeve is horizontally fixed to the rear end of the left bracket and the rear end of the right bracket; the left connecting pipe is horizontally fixed to the front end of the left bracket; the right connecting pipe is horizontally fixed to the front end of the right bracket; a left overturn support seat and a right overturn support seat are respectively mounted on the left side and the right side of the rear end of the upper berth assembly; and the upper berth assembly is mounted in the rear sleeve in a rotating and inserting manner through the left overturn support seat and the right overturn support seat. When the upper berth assembly overturns downwards to be beyond a dead point, the opposing force of an air spring can be acted as driving force to lock the upper berth assembly to a pin shaft, so that self locking of the upper berth assembly is realized. The air spring is used as a main support and locking component, and besides, the working principle of the dead point is combined, so that locking by using a locker being complex in structure is avoided. The berth device is simple and compact in structure, small in space usage, and firm and reliable in locking.

Description

technical field [0001] The invention relates to a sleeper device with self-locking function. Background technique [0002] At present, domestic trucks, especially tractors and trucks for domestic roads, are mostly equipped with a high-roof cab with a large space. Therefore, most of the high-roof cabs are equipped with double-deck sleepers to provide a good rest space for drivers and passengers. There are generally two states for the upper sleeper: when the vehicle is driving normally, the upper sleeper is in the state of being lifted, and the upper sleeper needs to be locked at this time to avoid the rapid displacement of the upper sleeper caused by braking and the danger of items falling. In China, the upper sleeper berth is mostly hoisted on the roof of the car by a pull belt. The main problem of this solution is that the pull belt can only bear the tension but not the pressure, so there will be abnormal noise during driving; when the driver and passengers are resting, th...

There are generally two states for the upper sleeper: when the vehicle is driving normally, the upper sleeper is in the state of being lifted, and the upper sleeper needs to be locked at this time to avoid the rapid displacement of the upper sleeper caused by braking and the danger of items falling. In China, the upper sleeper berth is mostly hoisted on the roof of the car by a pull belt. The main problem of this solution is that the pull belt can only bear the tension but not the pressure, so there will be abnormal noise during driving; when the driver and passengers are resting, the upper sleeper In the falling flat state, it is required that the berth should be locked firmly and reliably at this time. At present, most of the domestic use of mechanical locking devices requires a separate locking mechanism, which is more complicated and costly. Rigid collision, can produce severe noise
