The utility model discloses a side-impact passenger protection device of a B-pillar-free car door, which comprises a sliding door side safety hook and a front door side safety hook; the sliding door side safety hook is of a symmetrical structure in a shape like a Chinese character 'ji', and two sides of the sliding door side safety hook are fixed on the front side wall of the sliding door; the front door side safety hook is of an L-shaped symmetrical structure, and two sides of the front door side safety hook are fixed on the inner surface of the front door; the sliding door side safety hook and the front door side safety hook have a gap in the Y direction and have an overlapping portion in the projection of the two in the Y direction. The utility model discloses a protection device is when taking place the side impact, because safety hook's Y is minimum to the distance, can take place to interlock earlier and transmit the power that receives the qianmen for the sliding door, on the impact that the sliding door will receive transmitted comparatively firm panel beating on the automobile body, plays the effect of decomposing the transmission with power, reduces the invasion volume of qianmen.

Description

Side impact passenger protection device for B-pillar-free vehicle door

Technical Field

The utility model relates to a technical field of automobile design and manufacturing, more specifically say, the utility model relates to a passenger protection device is bumped to side of no B post door.

Background

When the side collision occurs in the B-pillar-free vehicle, due to the lack of the blocking of the B pillar to the side door, the vehicle door is easy to intrude inwards, and the safety of a passenger on a passenger cab is damaged.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem existing in the prior art, the utility model aims to provide a side impact passenger protection device of no B post door.

The utility model discloses a side collision passenger protection device of a B-pillar-free car door, which comprises a sliding door side safety hook and a front door side safety hook; the sliding door side safety hook is of a symmetrical structure in a shape like a Chinese character 'ji', and two sides of the sliding door side safety hook are fixed on the front side wall of the sliding door; the front door side safety hook is of an L-shaped symmetrical structure, and two sides of the front door side safety hook are fixed on the inner surface of the front door; the sliding door side safety hook is characterized in that the direction of a symmetry axis of the sliding door side safety hook is a Z-axis normal direction, the direction of the symmetry axis of the front door side safety hook is the Z-axis normal direction, a gap is formed between the sliding door side safety hook and the front door side safety hook in the Y direction, and the projections of the sliding door side safety hook and the front door side safety hook in the Y direction have an overlapping part.

Two sides of the sliding door side safety hook are fixed on the front side wall of the sliding door through bolts.

Wherein, the both sides of front door side safety couple pass through the bolt fastening on the internal surface of front door.

Compared with the prior art, the utility model discloses a passenger protection device is bumped to side of no B post door has following beneficial effect:

Detailed Description

The side impact occupant protection device of the present invention will be further described with reference to the following embodiments to help those skilled in the art to understand the technical solution of the present invention more completely, accurately and deeply.

Example 1

As shown in fig. 1 to 5, the side impact occupant protection apparatus of the B-pillar free door of the present embodiment includes a slide door side safety hook 40 and a front door side safety hook 20. The sliding door side safety hook 40 has a symmetrical structure in a shape like a Chinese character 'ji', and both sides of the sliding door side safety hook 40 are fixed to the front wall 31 of the sliding door 30 by bolts 50. The front door side safety hook 20 has an L-shaped symmetrical structure, and both sides of the front door side safety hook 20 are fixed to the inner surface of the front door 10 by bolts 50. Based on the XYZ coordinate system of the automobile, the direction of the symmetry axis of the sliding door side safety hook 40 is the Z-axis normal direction, the direction of the symmetry axis of the front door side safety hook 20 is the Z-axis normal direction, the sliding door side safety hook 40 and the front door side safety hook 20 have a gap in the Y-direction and the projections of the sliding door side safety hook 40 and the front door side safety hook 20 in the Y-direction have an overlapping portion.

In the embodiment, a gap is reserved between the sliding door side safety hook and the front door side safety hook in a normal state, the safety hook does not interfere in the door opening process, and the front door and the sliding door can be opened independently. When side collision occurs, the safety hook is firstly occluded due to the minimum Y-direction distance. Through the several style of calligraphy structures of self, be convenient for transmit the power that receives the qianmen for the sliding door, the impact that the sliding door will receive transmits comparatively firm panel beating on the automobile body, plays the effect of decomposing the transmission with power, reduces the invasion volume of qianmen.

To those skilled in the art, the specific embodiments are only exemplary descriptions of the present invention, and it is obvious that the present invention is not limited to the above embodiments, and various insubstantial modifications are included within the scope of the present invention as long as the method concept and the technical solution of the present invention are adopted.
