Description

Technical Field

[0001] The utility model relates to the technical field of vehicle-mounted power stations, in particular to a pulling mechanism for a vehicle-mounted power station. Background Art

[0002] The vehicle-mounted power station is placed in the carriage, and the opening doors and windows are set on the carriage. When using the power station or unit, the door is directly opened to connect the cables to prepare for power supply to the power station, and the operator can enter the carriage to operate. However, when multiple power stations or units are placed in the carriage, the power station obviously occupies a lot of space. When using or repairing the power station, it is limited by the space in the carriage and needs to be moved out of the carriage. In order to facilitate movement, a guide rail will be set at the bottom of the power station.

[0003] For example, the utility model patent with announcement number CN211930079U uses a motor and a lead screw on the base to drive the installation plate to move, and uses elastic paddles and oblique grooves to limit the pull-out length of the power station. The principle is feasible, but it is not applicable in actual use. The acceptance of the power station has strict restrictions on the weight of the whole vehicle and the height of the power station's overall dimensions. The above solution adds too much extra weight and increases the height of the power station in terms of overall dimensions, which is not conducive to the acceptance of the whole vehicle.

[0038] The utility model adopts ball matching to realize sliding, has a simple structure and is lightweight.

[0039] The fixed beam 4 has an L-shaped cross section, one side of the fixed beam 4 is connected to the bottom surface of the carriage (the carriage is not shown in the drawings), and the other side is connected to the first inner guide rail 1 .

[0040] Since the cabin chassis 21 where the power station 20 is located is usually welded by channel steel, "]" and "[" shaped grooves are generated on the left and right sides of its longitudinal section. The second inner guide rail 2 is fixedly connected to the grooves on the left and right sides, so that the guide rail assembly can be placed in the groove, minimizing the space occupancy.

[0041] In order to prevent derailment, both ends of the outer guide rail 3 are provided with limit posts 5 on the surfaces facing the first inner guide rail 1 and the second inner guide rail 2. A pin 61 is fixedly provided at the end of the first inner guide rail 1 away from the extraction direction, and a pin 62 is fixedly provided at the end of the second inner guide rail 2 close to the extraction direction. The pin located in the same guide groove is located between the two limit posts, and the pin and the limit post cooperate to prevent the inner guide rail or the outer guide rail from derailing.

[0042] The utility model adopts the cooperation of the inner guide rail and the outer guide rail, changes the traditional vertical loading into the horizontal loading, and the protruding parts are only the fixed beams, and does not increase the original height of the power station.

[0043] It also includes a latch assembly, which is used to achieve position locking of the power station 20. Specifically, the latch assembly includes a fixed plate 7 fixed on the cabin chassis 21, and a latch 8 is slidably connected to the fixed plate 7, and the movable direction of the latch 8 is perpendicular to the pulling direction of the power station; the fixed plate 7 is provided with fixed blocks 9 located on the upper and lower sides of the latch 8, and a movable block 10 is fixed on the latch 8. The latch 8 is also sleeved with an elastic member 11, and the elastic member 11 is located between one side of the fixed plate and the movable block 10; at the same time, a latch hole is provided on the fixed beam 4, and the elastic member 11 is compressed when the latch 8 enters the latch hole, and at the same time, the latch 8 is rotated to make the movable block 10 and the fixed block 9 tend to a vertical position, so that the latch 8 is locked, and the guide rail cannot be pulled out after locking.

[0044] The pull-out mechanism provided by the utility model has a light structure and a small volume, does not add excessive extra weight, does not increase the original height of the power station, is conducive to the acceptance of the entire vehicle, and is convenient for actual use.
