Background

When a pulling device (for example, a pulling box) is disposed in a passenger cabin of a vehicle, as shown in fig. 1 to 3, the pulling device is taken as a front-rear direction of the vehicle, the pulling direction of the pulling device is taken as a rear-front direction, and the pulling device generally comprises a base assembly 1, a strip-shaped lock tongue a, a pulling piece 2, an outer protecting plate 3, a handle assembly 4, a fixed shell 5 and a containing shell J, wherein the pulling piece 2 is a cuboid box hopper with an upper opening, the base assembly 1 is located below the pulling piece 2, a sliding rail structure (not shown) for enabling the pulling piece 2 to complete pulling action is disposed between the base assembly 1 and the pulling piece 2, the outer protecting plate 3 is disposed outside the left and right surfaces of the pulling piece 2, the containing shell J is connected with the pulling piece 2 into a whole, the front portion of the containing shell J is sealed with the front portion of the pulling piece 2, the containing shell is provided with a partial structure higher than the pulling piece 2, the strip-shaped lock tongue a penetrates the containing shell J and penetrates the containing shell J when the pulling piece 2 is in a locked state, the containing shell is provided with a through hole D, the strip-shaped lock tongue a can be controlled to extend out of the containing shell 4, and can be connected with the fixed shell B on the outer side of the front side of the handle assembly 5B of the containing shell B. Therefore, when the drawing device is in a locking state, the strip-shaped lock tongue A passes through the through hole D and stretches into the lock box B to be clamped with the fixed shell 5, and when the drawing piece 2 needs to be drawn out, the strip-shaped lock tongue A contracts and releases the clamping with the fixed shell 5 towards the inside of the drawing device along the left-right direction of the real vehicle under the drive of the buckle assembly 4, so that the drawing piece 2 can be drawn out along with the buckle assembly 4.

Referring to fig. 4 to 5, the accommodating housing J is further provided with an accommodating portion K, a first transmission portion E, a torsion spring I and two second transmission portions F, wherein a concave area is provided in a middle portion of the accommodating portion K, the first transmission portion E, the second transmission portion F and the torsion spring I are disposed in the concave area, the two second transmission portions F are disposed on two sides of the first transmission portion E left to right and rotatably disposed on the accommodating portion K, a pair of strip-shaped lock bolts a are disposed on a rear side of the second transmission portion F and connected to the second transmission portion F, and the torsion spring I is disposed on a lower side of the first transmission portion E.

Specifically, two end parts of the torsion spring I are respectively propped against the lower part of the first transmission part E and the lower part of the concave area; teeth are arranged on the left and right side surfaces of the lower part of the first transmission part E, and the upper part of the first transmission part E is cuboid; correspondingly, the second transmission part F is a special-shaped piece, and teeth are also arranged on the surface of the second transmission part F facing the first transmission part E, and the second transmission part F is meshed with the lower part of the first transmission part E by virtue of the tooth characteristics; meanwhile, a sliding column G extending along the front-rear direction of the real vehicle is arranged at the end part of the second transmission part F far away from the first transmission part E, and a matching groove H which can enable the sliding column G to slide therein is arranged at the position corresponding to the sliding column G on the strip lock tongue A and is arranged along the up-down direction of the real vehicle.

In response to the above, the handle assembly 4 includes a handle body 41 capable of rotating up and down and a follower 42 connected to the rear of the handle body 41, the follower 42 being located above the first transmission E and being capable of applying a downward force to the first transmission E when the handle assembly 4 rotates. Thus, when the handle body 41 rotates upwards under the action of external force, the follower 42 will move downwards and apply a downward force to the first transmission portion E, so that the first transmission portion E moves downwards and elastically deforms the torsion spring I, and meanwhile, the second transmission portions F located on the left and right sides of the first transmission portion E are driven to rotate; at this time, the second transmission part F located at one side of the first transmission part E will rotate in the counterclockwise direction, the second transmission part F located at the other side of the first transmission part E will rotate in the clockwise direction, and the two second transmission parts F will drive the strip-shaped lock bolts a connected with each other to move towards the center of the accommodating part K, so that the strip-shaped lock bolts a release the clamping connection with the fixed housing 5, the unlocking of the drawing device is completed, and the drawing member 2 can be drawn out; similarly, when the external force is removed, the first transmission portion E will move upwards under the elastic restoring force of the torsion spring I, and the strip-shaped lock tongue a will reset and be clamped with the fixed housing 5 again, so that the drawing device returns to the locked state. It should be noted that, in order to ensure that the strip-shaped lock tongue a moves along the left-right direction of the real vehicle when moving, the strip-shaped lock tongue a is limited in the up-down direction in the related art, and this limiting effect can be achieved by constructing the shape of the accommodating portion K or adding an additional limiting member, which is not described herein.

The disadvantage of the above-described arrangement of the drawer is that the optimization space for the feel of a jerk during locking is limited; specifically, in order to reduce the shock feeling during locking of the strip-shaped lock tongue a and improve the operation smoothness in the related art, an inclined plane is usually disposed at the end portion of the strip-shaped lock tongue a, which is used for locking with the fixed housing 5, however, because the length of the strip-shaped lock tongue a is limited, the gradient of the inclined plane which can be disposed thereon is also limited, and the effect of adjusting the smoothness when the drawing device is drawn by adjusting the strip-shaped lock tongue a is limited.
