The fixing piece and the nut are arranged at the two ends of the fixing column correspondingly, limiting of the first rotating piece and the second rotating piece is achieved, and when the first rotating piece and the second rotating piece rotate to the supporting framework, the limiting sleeve and the supporting framework are pushed to continue rotating, so that damping in the rotating process is achieved, and the protective cover is prevented from being lifted to lose protection.

The present invention discloses a power supply device for auxiliary equipment of new energy vehicles, which relates to the field related to new energy vehicles, including a box installed at the installation position of the auxiliary equipment of the new energy vehicle, a battery assembly is installed at the top internal position of the box, and the power connection position of the battery assembly is connected to the power supply of the auxiliary equipment of the new energy vehicle through the power transmission assembly; and also includes: a placement plate for placing the battery assembly is arranged inside the box, and a limiting mechanism is arranged at the bottom of the placement plate, and the linkage work of the limiting mechanism drives the interference mechanism to act on the damping spring to prevent the elastic force of the damping spring from causing the battery assembly to move. The power supply device for auxiliary equipment of new energy vehicles is provided with an interference mechanism. Through the auxiliary setting of the interference mechanism, the damping effect of the damping spring can be changed, resulting in the box and the battery assembly being effectively prevented from being worn at the bottom of the battery assembly during the stabilization process.

The utility model relates to the related technical field of data transmission docking stations, in particular to a data transmission docking station with an anti-falling function, which is characterized in that a transverse buffer pad and a mounting plate are arranged on the surface of an impact-resistant shell, a limiting groove is formed in the impact-resistant shell, and a side end buffer pad is arranged on the surface of the mounting plate; positioning columns and springs are arranged on the surface of the data transmission docking station, sliding grooves are formed in the surfaces of the positioning columns, sliding holes are formed in the sliding columns, and limiting plates are arranged on the surfaces of the sliding columns; the device has the beneficial effects that the effect of buffering the impact-resistant shell for the first time is achieved through a transverse buffering pad, impact force transmitted into the impact-resistant shell is reduced, the effect of damping a spring is achieved through a sliding column, therefore, the impact force is converted into heat energy to be dissipated, meanwhile, the sliding column achieves the effect of supporting a limiting plate, and the service life of the limiting plate is prolonged. The effect of buffering the impact force is achieved through the springs, and therefore the situation that the impact force is transmitted to the data transmission docking station to cause damage is avoided.

The present invention provides a valve actuator. One side of the valve actuator of the present specification includes: a housing; a motor configured in the housing; a drive gear combined to a motor shaft of the motor; a transmission gear externally tangent to the drive gear, which rotates according to a predetermined gear ratio when the drive gear rotates; an output gear combined to an output shaft and externally tangent to the transmission gear; and a stopper configured in the housing to limit the rotational radius of the output gear. The transmission gear includes: an outer side portion; an inner side portion configured inside the outer side portion; a first magnet configured in the outer side portion; and a second magnet configured in the inner side portion and opposite the first magnet. Thus, gear damage caused by excessive torque can be prevented, and gear damage caused when the output gear contacts the stopper can be prevented.

The utility model discloses a damping bowl set which comprises an inner ball plug and a steel ball bowl arranged outside the inner ball plug in a sleeved mode, a gap is formed between the steel ball bowl and the inner ball plug, and a damping piece is arranged at the position, close to the bottom, of the gap between the steel ball bowl and the inner ball plug. A steel ball is arranged in a gap between the steel ball bowl and the inner ball plug and close to the top; the damping device has the advantages that through the steel ball bowl, the inner ball plug, the damping piece and the steel ball, when the inner ball plug rotates, due to the fact that the inner ball plug is attached to the damping piece, the inner ball plug slides on the damping piece, the vibration reduction and damping effects are achieved, in other words, after the inner ball plug is pushed, the inner ball plug can move upwards, and therefore the damping effect is achieved. The steel ball bowl and the inner ball plug generate mutual pushing force, so that the inner ball plug is tightly attached to the damping piece, meanwhile, the inner ball plug is attached to the steel ball to rotate, the clamping condition is avoided, and the vibration reduction and damping effects can be achieved.
