The invention discloses a door plate control method of an air conditioner. The method comprises following steps: a door plate of the air conditioner is controlled to move in the first direction; when the door plate moves to the pre-warned position, warning information is sent out, and whether the door plate encounters the obstacle or not is detected; if the door plate encounters the obstacle, the stagnant position of the door plate when the door plate encounters the obstacle is recorded, the door plate is controlled to move towards the second direction by a first preset distance, when the door plate moves by the first preset distance, the door plate is controlled again to move towards the first direction, and warning information can be sent out when the door plate is away from the stagnant position by the second preset distance; a user can be effectively warned while whether the obstacle exists or not is detected. The invention further discloses a door plate control device of the air conditioner and the air conditioner.

A method for controlling safe operation of an electric table includes: starting the default setting value or self-set setting value of a sensor unit stored in a memory after power-on; making sure that an electric control module activates the sensor unit when the electric table is raised or lowered, and the sensor unit detects the vibration amplitude of the electric table and records the number of vibrations when the vibration amplitude exceeds the setting value; when the recorded number of vibrations is greater than the default setting value or self-set setting value, the electric control module controls a power mechanism on the electric table to make a rebound action in the opposite direction when the electric table is raised or lowered. Acceleration and gyroscope sensors are vertically installed on a small board, so that the sensitivity of the gyroscope to vibration detection is increased.

The invention relates to an escalator with an anti-clamping device, which comprises a step, the step is divided into an entry section, an ascent section and an exit section; a set of apron plates, fixed on both sides of the step; a set of handrails Belts are respectively movably installed on the apron panels; a set of active anti-pinch mechanisms are respectively provided on the inner lower part of the apron panels corresponding to the entry section; a set of fixed anti-pinch mechanisms are respectively provided on the ascending section and exit section. The inner lower part of the apron plate corresponding to the section; the electric control system is used to connect the driving mechanism and the high-pressure fan to the external power supply, and control the working process of the driving mechanism and the high-pressure fan. On the basis of further improving the fixed position limiting and anti-pinch mechanism, the present invention can effectively increase the active position limiting and anti-pinch mechanism, and can effectively form a tactile reminder, thereby forming a better anti-pinch effect.

The invention provides a vehicle and a sunroof assembly thereof. The sunroof assembly comprises a sunroof, a sunroof driver, an acceleration sensor, a supporting block, a supporting block driver and a control unit, wherein the acceleration sensor is used for detecting the acceleration of the sunroof; the supporting block driver is connected with the supporting block, and is used for driving the supporting block to move between a resisting position where the supporting block resists the sunroof and a separation position where the supporting block is separated from the sunroof; and in the sunroof closing process, the supporting block driver drives the supporting block to move to the resisting position to increase acceleration change when the sunroof pinches objects, and the control unit can stop the sunroof from being closed and move towards an opening direction according to the magnitude of the acceleration of the sunroof. Therefore, in the sunroof closing process, the temporary rigidity of the sunroof is increased by enabling the supporting block to resist the sunroof, the acceleration change of the sunroof when the sunroof pinches the objects is increased, therefore the control unit can stop the sunroof from being continuously closed in time and the situation that the sunroof pinches hands is effectively prevented from occurring.

The invention relates to the technical field of escalators, in particular to a safe and reliable escalator. The safe and reliable escalator comprises a handrail breast board, an apron board and a stair. An inner cover plate is arranged between the apron board and the handrail breast board. The apron board comprises an upper apron board body and a lower apron board body. The lower apron board body is arranged at the side edge of the stair, and an apron board safety protection device is connected to the lower apron board body. The upper apron board body comprises an arc-shaped anti-clamping part. The arc-shaped anti-clamping part is arranged on the stair and covers the side edge of the stair. The side edge of the stair is provided with a groove formed in the longitudinal direction. The arc-shaped anti-clamping part is provided with a blocking part stretching into the groove. The outer side of the blocking part is provided with a protection strip. According to the safe and reliable escalator, an object can be effectively prevented from entering a gap between the apron board and the stair by arranging the arc-shaped anti-clamping part, and the size of a clearance between the arc-shaped anti-clamping part and the end surface of the stair is adaptively adjusted along with the change of the seasonal temperature, so that the clearance is kept in a reasonable and safe range, and the situation that the apron board is stuck due to the fact that the apron board makes contact with the stair is prevented.

The invention relates to the technical field of high-speed rail, in particular to a high-speed rail door with an anti-pinch function, including a high-speed rail door body, a mounting groove is opened on one side of the high-speed rail door body, and a second magnetic block is bonded inside the mounting groove. One side of the block is provided with a first magnetic block, a spring slot is opened inside the installation groove, and a first spring is arranged inside the spring slot, and a moving conductor block is welded on one side of the first spring, and one side of the moving conductor block is away from One outer wall of the first spring is threadedly connected with an insulating guide rod, and one side of the moving conductor block is provided with two fixed conductor blocks distributed up and down. The present invention utilizes the mutual repulsion between the first magnetic block and the second magnetic block by setting the first magnetic block and the second magnetic block, so that a relatively flexible magnetic buffer zone is formed between the first magnetic block and the second magnetic block, and then The action of the first magnetic block is used to make the high-speed rail door body stop and close with high sensitivity, so as to achieve a good anti-pinch effect.
