It should be noted that: the relative arrangement of the components and steps, the numerical expressions and numerical values set forth in these embodiments do not limit the scope of the present invention unless specifically stated otherwise.
The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses.
Techniques, methods, and apparatus known to those of ordinary skill in the relevant art may not be discussed in detail but are intended to be part of the specification where appropriate.
In all examples shown and discussed herein, any particular value should be construed as merely illustrative, and not limiting. Thus, other examples of the exemplary embodiments may have different values.
It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, further discussion thereof is not required in subsequent figures.
According to the figure 1, the invention provides an automobile B-pillar upper connecting structure, which comprises an automobile body covering part 1, a B-pillar inner plate 3 and a B-pillar upper connecting piece 5, wherein the automobile body covering part 1 and the B-pillar inner plate 3 are mutually attached and connected, and the middle parts of the automobile body covering part 1 and the B-pillar inner plate 3 are sunken towards the direction far away from each other to form a reinforcing cavity.
A B-column reinforcing plate 2 and a B-column upper hinge reinforcing plate 4 are arranged in the reinforcing cavity, two ends of the B-column reinforcing plate 2 are connected between the connection part of the vehicle body covering part 1 and the B-column inner plate 3, and the B-column reinforcing plate 2 is sunken towards the direction of the vehicle body covering part 1; the B-pillar upper hinge reinforcing plate 4 is arranged in the groove of the B-pillar reinforcing plate 2.
The B-pillar upper connecting piece 5 is arranged between the B-pillar inner plate 3 and the B-pillar reinforcing plate 2, and two ends of the B-pillar upper connecting piece are connected between the joint of the B-pillar inner plate 3 and the B-pillar reinforcing plate 2. In the implementation, the invention adds a B-pillar upper connecting piece 5 which is mainly arranged in a transition area with a reduced Y-direction section on the upper part of the B-pillar, namely a flexible area; the X of B post upper portion connecting piece 5 is connected (being the junction of automobile body covering 1 and B post inner panel 3 in fig. 1) to running through B post cross-section and B post front and back tang, makes this department cross-section X of B post promote to a great extent to stability, greatly increases B post cross-section Y to crushing power, and is showing B post upper segment structural stability, intensity performance promotion.
Further, the middle portion of the B-pillar upper joint 5 is provided with a bulge 51 toward the B-pillar inner panel 3. In implementation, the middle of the B-pillar upper connecting piece 5 is provided with an X-direction elongated protrusion 51, and the protrusion 51 can improve the rigidity of the protrusion 51, but the height of the protrusion 51 is not too high, so that structural instability of the B-pillar upper connecting piece 5 in the X direction is prevented when the Y direction collides or presses the B pillar.
Still further, gaps are arranged at the joints of the two ends of the bulge part 51 and the B-column upper connecting piece 5 and the B-column inner plate 3. When setting up, the X of bulge 51 to length can not exceed the welding seam allowance, when avoiding the B post to receive the extrusion, bulge 51 can cause the extrusion to the welding seam allowance to lead to the holistic intensity of B post to reduce.
Further, the joints of the B-pillar upper joint 5 with the vehicle body covering 1, the B-pillar reinforcement panel 2, and the B-pillar inner panel 3 are connected by spot welding or laser welding. The reinforced cavity is sealed, and the overall strength of the B column is effectively improved.
Furthermore, the connecting part is at least provided with an upper row of welding spots and a lower row of welding spots or a laser welding seam with the length of 45mm, so that the connecting strength can be effectively ensured.
Further, the B-pillar upper hinge reinforcing plate 4 is attached to the concave part of the B-pillar reinforcing plate 2 and connected with the B-pillar upper hinge reinforcing plate through spot welding. So that the B-pillar upper hinge reinforcing plate 4 and the B-pillar reinforcing plate 2 are integrated, and the overall strength of the B-pillar reinforcing plate 2 is improved.
Still further, the middle of the recessed portion of the B-pillar reinforcement plate 2 is also protruded toward the B-pillar upper hinge reinforcement plate 4. The strength of the whole structure of the B-pillar reinforcing plate 2 is improved, and the irregular wave shape of the B-pillar reinforcing plate has better bending resistance compared with a straight plate structure.
Still further, the middle part of the B-pillar upper hinge reinforcing plate 4 protrudes towards the direction of the B-pillar upper connecting piece 5, and the gap between the protruding part of the B-pillar upper hinge reinforcing plate 4 and the protruding part of the B-pillar reinforcing plate 2 is at least 3 mm. When in implementation, the protruding part of the B-pillar upper hinge reinforcing plate 4 and the B-pillar upper connecting piece 5 keep a gap of more than 3 mm; when the B column is prevented from being collided or extruded in the Y direction, the protruding part of the hinge reinforcing plate 4 on the B column interferes with the upper connecting piece 5 of the B column, and the upper connecting piece 5 of the B column is unstable.
The novel B-column upper connecting structure provided by the invention is characterized in that the problems of great increase of weight and cost caused by schemes of greatly increasing the material thickness of a B-column reinforcing plate 2, increasing or reinforcing a B-column upper hinge reinforcing plate 4 and the like aiming at easy bending and X-directional instability of the upper part of a B column are solved by newly adding the B-column upper connecting piece 5 and the connecting structure.
Although some specific embodiments of the present invention have been described in detail by way of examples, it should be understood by those skilled in the art that the above examples are for illustrative purposes only and are not intended to limit the scope of the present invention. It will be appreciated by those skilled in the art that modifications may be made to the above embodiments without departing from the scope and spirit of the invention. The scope of the invention is defined by the appended claims.
