technical field

The invention relates to a stable train sleeper bed, which belongs to the technical field of sleeper beds.

Background technique

At present, known train hard berths all are to be rigidly connected and fixed with the train compartment. Every holiday time, especially during the peak period of passenger flow in our country, the seats are particularly tight. Passengers who have to sit for more than ten hours want to buy a hard sleeper to travel, but when the train is moving, there will always be back and forth shaking, which makes people feel uncomfortable. Sleeping passengers woke up with a start, resulting in a significant drop in sleep quality and seriously affecting the quality of travel.

Contents of the invention

The technical problem to be solved by the present invention is to provide a stable train sleeper bed, which can not only solve the problem that the train hard sleeper bed does not shake with the shaking of the train body, but also can be easily installed on the train to solve the above-mentioned existing problems. problems in technology.

The technical solution adopted by the present invention is: a stable train sleeper bed, including a bed body and a fixed bracket, the bed body is connected to the fixed bracket through two horizontal guide rail pairs, four corners of the bed body are installed horizontally in the same direction as the carriage. Rack, four micro-motors are installed on the four corners of the fixed bracket, the output shaft of the micro-motor is fixedly connected with a gear meshed with the rack, and a three-way accelerometer and a gyroscope are also installed on the bed body.

Preferably, the micro-motor is connected to the control terminal of the controller, and the signal input terminal of the controller is connected with a three-way accelerometer and a gyroscope.

Preferably, the above-mentioned controller adopts an embedded core control chip.

Preferably, the above-mentioned three-way accelerometer and gyroscope are connected to the controller through a Kalman filter.

Preferably, each horizontal guide rail pair includes a guide rail bar and two sliders installed on the guide rail bar, the guide rail bar is fixedly connected to the fixed bracket, facing the length direction of the carriage, and the two sliders are fixedly connected to the bottom of the bed body .

Preferably, elastic buffer blocks are provided at both ends of each horizontal guide rail pair.

Preferably, the elastic buffer block is provided with a pressure sensor, the pressure sensor is connected to the signal input terminal of the controller, and a control terminal of the controller is also connected to a voice playback device for reminding passengers of excessive impact.

Beneficial effects of the present invention: Compared with the prior art, the present invention measures the acceleration and angular velocity of the bed through the three-way accelerometer and gyroscope, and feeds back the acceleration and angular velocity to the controller, and the controller controls the bed body according to the acceleration and angular velocity The micro-motors at the four corners rotate to realize the reverse movement of the vibration of the train hard sleeper bed, ensuring that the train hard sleeper bed will not shake with the vibration, so that the passengers sleeping on the bed will not feel shaking, and the sleep quality of the passengers can be greatly improved. , and the present invention also has the characteristics of simple structure and convenient installation, and through the elastic buffer block made of rubber at both ends of the horizontal guide rail pair, the slider hits the elastic buffer block to further play a safety role. When an excessive impact occurs, It plays a buffer role, and when the impact is too large, the pressure sensor can detect the impact pressure. When the pressure value received by the controller reaches the set threshold, the voice playback device is controlled to remind passengers to improve the safety of use.
