Detailed Description

The following detailed description of specific embodiments of the present disclosure is provided in connection with the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.

In the present disclosure, unless otherwise specified, the use of the directional terms such as "up and down" generally means "up and down" in a state where the front pillar assembly of the automobile is mounted on the vehicle, and the direction coincides with the direction of "up and down" when the vehicle is normally running. In addition, the terms "first", "second", "third", and the like used in the embodiments of the present disclosure are for distinguishing one element from another, and have no order or importance.

As shown in fig. 1-3, in accordance with one aspect of the present disclosure, an automotive front pillar assembly 100 is provided. Which includes a shock absorber body 10 and a zigzag spring 20. The shock absorber body 10 includes a shock absorber tube 30, a piston rod 40, a first spring seat 50 and a second spring seat 60, the piston rod 40 is slidably inserted into the shock absorber tube 30, the first spring seat 50 is fixedly disposed on the piston rod 40, the second spring seat 60 is fixedly disposed on the shock absorber tube 30, the Z-shaped spring 20 is sleeved on the piston rod 40 and the shock absorber tube 30, and two ends of the Z-shaped spring 20 are respectively abutted against the first spring seat 50 and the second spring seat 60.

With the above arrangement, when the automotive front pillar assembly 100 is mounted on a vehicle, the zigzag spring 20 is in a compressed state and is in contact with the first spring seat 50 and the second spring seat 60, so that the zigzag spring 20 can deform to absorb road impact, thereby achieving a cushioning effect. For the technical scheme who adopts coil spring among the prior art, because there is not the spring coil among the coil spring in the Z style of calligraphy structure of Z style of calligraphy spring 20, the interval is great between three plates of constituteing Z style of calligraphy spring, and connect to be the angle between the plate, when receiving the impact force, the angle between the plate diminishes in order to absorb the impact, can not contact each other between the plate, consequently, when receiving the impact, Z style of calligraphy spring 20 can not produce abnormal sound.

At present, the front pillars of the automobile generally adopt the spiral springs, and the ends of the spiral springs are not flat due to winding forming during manufacturing of the spiral springs, so that the front pillars of the automobile can not be in effective contact with the spring seats. The end head is uneven and unbalanced in stress, and abnormal sound can be generated at the contact surface of the end head and the spring seat. And because the stress area of the spiral spring is small, the impact force cannot be dispersed rapidly when being buffered, the impact pressure is high, and the abrasion is easy to generate at the contact surface.

In order to smoothly buffer the impact force, as shown in fig. 3, the zigzag spring 20 may include a first plate 21, a second plate 22, and a connection plate 23. The first plate 21 and the second plate 22 are arranged in parallel. The connecting plate 23 is connected obliquely between the first plate 21 and the second plate 22. A first abutting flat surface 51 is provided on a side of the first spring seat 50 facing the second spring seat 60, a second abutting flat surface 61 is provided on a side of the second spring seat 60 facing the first spring seat 50, and the first flat plate 21 and the second flat plate 22 abut against the first abutting flat surface 51 and the second abutting flat surface 61, respectively.

The automobile front pillar assembly 100 in the present disclosure employs the Z-shaped spring 20, and the first plate 21 and the second plate 22 are in planar contact with the first spring seat 50 and the second spring seat 60, respectively, so that the force-receiving area can be significantly increased, when receiving an impact force, the impact force can be rapidly transmitted to the Z-shaped spring 20, and the Z-shaped spring 20 is deformed to buffer the impact force, thereby improving the shock absorption effect of the automobile front pillar assembly 100 and improving the comfort of the vehicle. The zigzag spring 20 is a bent plate-shaped structure, and the width of the zigzag spring is much larger than the diameter of the coil spring, so that a larger elastic force can be stored.

Further, as shown in FIG. 3, the angle between the first plate 21 and the web 23 may be approximately 30-40, and the angle between the second plate 22 and the web 23 may be approximately 30-40. Therefore, the Z-shaped spring 20 can be ensured to have enough rigidity to meet the shock absorption requirement of the automobile front pillar assembly 100, and the first flat plate 21, the second flat plate 22 and the connecting plate 23 can be ensured to have enough distance, so that the Z-shaped spring 20 cannot collide with each other to generate abnormal sound after being compressed. Furthermore, it is convenient that the first plate 21 and the second plate 22 are aligned with each other in the vertical direction so as to be sleeved on the piston rod 40. It should be noted that the specific values of the included angle between the first plate 21 and the connecting plate 23 and the included angle between the second plate 22 and the connecting plate 23 are not limited in the present disclosure, and may be any suitable angle as long as a sufficient distance between the connecting plate and the first plate 21 and the second plate 22 can be ensured.

As shown in fig. 3, the first plate 21 and the connecting plate 23 are connected by a first arc connecting portion 24, and the second plate 22 and the connecting plate 23 are connected by a second arc connecting portion 25. The first flat plate 21, the second flat plate 22 and the connecting plate 23 are connected in a smooth transition manner through the first arc connecting portion 24 and the second arc connecting portion 25, so that stress concentration at the connecting position can be avoided, the Z-shaped spring 20 has enough strength as a whole, and the Z-shaped spring is not easy to damage when buffering impact force.

The first plate 21 has a first through hole 211, the second plate 22 has a second through hole 221, and the connecting plate 23 has a third through hole 231. The zigzag spring 20 is sleeved on the piston rod 40 and the shock absorber tube 30 through the first through hole 211, the second through hole 221 and the third through hole 231, so that the zigzag spring 20 can be conveniently and stably fixed to the shock absorber body 10.

As shown in fig. 3, in one embodiment of the present disclosure, the third through hole 231 is a long hole extending in the length direction of the connection plate 23, one of the first through hole 211 and the second through hole 221 is a long hole (specifically, may be a waist-shaped hole) extending in the length direction of the flat plate, and the other is a circular hole. The longitudinal direction is a direction a in fig. 3.

As shown in FIG. 1, during installation, the circular hole in the zigzag spring 20 is fitted over the damper cylinder 30. By providing the long holes in the zigzag springs 20, the weight of the zigzag springs 20 can be effectively reduced. The combination of the round hole and the long hole can reduce the assembly requirement and the machining precision requirement.

Further, as shown in fig. 3, the first through hole 211 may be opened in the middle of the first plate 21, and the second through hole 221 may be opened in the middle of the second plate 22, so that the force applied to each position of the first plate 21 and the second plate 22 may be uniformly applied, and the applied impact force may be rapidly dispersed.

In order to reduce wear between the zigzag spring 20 and the first spring seat 50, in one embodiment of the present disclosure, a vibration isolation pad (not shown) may be disposed between the zigzag spring 20 and the first spring seat 50. Specifically, as shown in fig. 2, the vibration-isolating pad may be disposed between the first flat plate 51 and the first abutment flat surface 51 of the first spring seat 50. Rigid contact between the Z-shaped spring 20 and the first spring seat 50 can be avoided by arranging the shock insulation pad, so that abrasion between the Z-shaped spring 20 and the first spring seat 50 can be reduced, and impact force can be further buffered. Wherein, the shock insulation cushion can adopt a rubber cushion.

In the present disclosure, the material of the zigzag spring 20 is not limited. In one embodiment of the present disclosure, the material of the zigzag spring 20 may be spring steel. The spring steel has excellent comprehensive performance, particularly has excellent elastic limit, strength limit and yield ratio, so that the Z-shaped spring 20 can store larger elastic potential energy, is not easy to damage and has long service life.
