Description

Technical Field

[0002] The door anti-collision beam is a crossbeam device added to the internal structure of the car door to strengthen the side structure of the vehicle. The main purpose is to prevent the door from deformation or damage in a collision, thereby ensuring the safety of the passengers in the car. This device is usually made of high-strength steel or aluminum alloy and is installed inside the door. It is not visible from the outside. The door anti-collision beam generally adopts a diagonal structure, extending from the bottom door frame to the bottom edge of the window glass.

[0003] The shapes of the anti-collision beam under the car door are mainly divided into tubular and cap-shaped. The cap-shaped anti-collision beam is more common in European and American models. It is generally directly welded on the car door. There are mainly single-cap shapes (U-shaped) and double-cap shapes (M-shaped). Most of the existing hot-pressing forming molds for the anti-collision beam under the car door can only perform hot-pressing on the anti-collision beam of a single shape, and the functionality is low.

[0015] The beneficial effects of the present invention are:

[0016] 1. The present invention adopts the structural design of the upper mold, the lower mold and the adjustment mechanism, so that the triangular bar is connected with the lower mold to form a U-shaped hot pressing state, and the triangular bar is connected with the movable plate to form an M-shaped hot pressing state. It can be applied to the hot pressing forming of U-shaped and M-shaped door anti-collision beams at the same time, improves the functionality, and solves the low functionality of the current hot pressing forming mold of the lower anti-collision beam of the door.

[0017] 2. The present invention also designs a lifting mechanism structure so that the output shaft of the motor B of the external control mechanism rotates, so that the worm drives the worm ring to rotate, so that the ball block moves in the descending thread groove, the limit arc groove C and the ascending thread groove, causing the guide ball block to move in the limit arc groove A, the descending inclined groove, the ascending inclined groove and the limit arc groove B, and the limit block rotates relative to the limit rotation groove. Among them, when the ball block moves in the descending thread groove, the guide ball block moves in the limit arc groove A, the guide column descends, while the guide ring and part of the ring block remain in position, the movable plate and the adjustment mechanism descend first, and the hot-pressed plate of the door anti-collision beam is pressed into a V shape, and the ball block is at the bottom. When moving in the limiting arc groove C, the guide ball block moves in the descending inclined groove. At this time, the positions of the movable plate and the adjusting mechanism remain unchanged to ensure the V-shaped hot pressing effect. The guide ring and part of the ring block descend to drive the upper module to press down to hot press the V-shaped plate into an M-shaped door anti-collision beam. Then, the guide ball block moves at the end of the limiting arc groove A, and the guide ball block moves on the limiting arc groove B. The positions of the movable plate, the adjusting mechanism and the upper module all remain stationary to ensure the hot pressing effect of the M-shaped door anti-collision beam.

[0019] 4. The present invention facilitates the connection between the adjustment mechanism and the movable plate through the structural design of the jacking assembly.

[0020] 5. The present invention further designs the guide assembly so that the slide rod and the ball block have a certain rotation space, and when the slide rod and the ball block rotate at a certain angle, the V-shaped guide groove rotates relative to the hemispherical block. Under the elastic force of the spring B, the movable column drives the ball block to apply a force to the inclined surface of the V-shaped guide groove, which facilitates the resetting of the slide rod and the ball block.
