Detailed Description

The following detailed description of embodiments of the utility model refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present invention, are given by way of illustration and explanation only, not limitation.

Fig. 1 and 2 show an instrument panel cross member support assembly including an instrument panel cross member 20, a dash panel metal connecting bracket 10 connected to the instrument panel cross member 20, and the like. The front wall sheet metal of the vehicle body can be connected to one end of the front wall sheet metal connecting bracket 10 away from the dashboard cross member 20 by fasteners and the like so as to be stably positioned. An instrument panel positioning and mounting bracket 40 for providing positioning and connecting support for an instrument panel framework is connected to one side of the automobile instrument panel beam 20 facing to a passenger compartment, and positioning holes and screw holes can be formed in the instrument panel positioning and mounting bracket 40 so as to position the instrument panel framework through fasteners; a wire harness through hole 41 may be formed on a sidewall of the instrument panel positioning and mounting bracket 40 for routing and securing a wire harness.

In the above dashboard cross beam assembly, the utility model provides a front wall sheet metal connecting bracket 10, which comprises a first supporting bracket 11 connected to a dashboard cross beam 20 and a second supporting bracket 12 connected to one end of the first supporting bracket 11 far away from the dashboard cross beam 20 and used for connecting a vehicle body front wall sheet metal.

As shown in fig. 3 and 4, at the end portions of the first support bracket 11 and the second support bracket 12 opposite to each other, they may be riveted to each other by aluminum rivets 14, whereby the end of the second support bracket 12 facing the instrument panel cross member 20 is overlaid on the outer surface of the end of the first support bracket 11 facing away from the instrument panel cross member 20. When the automobile collides, the collision impact force is transmitted to the second support frame 12 through the front wall metal plate of the automobile body, and the second support frame 12 bears the preset impact action and generates the shearing action with the first support frame 11 at the aluminum rivet 14. Because the connection strength of the aluminum rivets 14 is smaller than the structural strength and the welding strength of the stamped plate and the shearing strength is smaller, the aluminum rivets can be broken under the shearing action, so that the first support frame 11 and the second support frame 12 are failed to be connected, the dislocation collapse towards the automobile instrument panel cross beam 20 is generated, and the direct impact on the automobile instrument panel cross beam 20 is avoided. Therefore, the second support frame 12 and the connected front wall metal plate move backwards towards the automobile instrument panel beam 20, a deformation buffer space is provided for the front engine room, and the situation that parts in the front engine room invade the passenger room to cause injury to passengers is avoided.

The riveting position, the riveting technological parameters, the number of rivets and the diameter of the rivets can be flexibly adjusted according to the collision safety requirements so as to ensure that the connection and the fastening are reliable when collision does not occur, and the rivets can break and fail in time when the collision strength generated by collision reaches a set threshold value.

According to the above, the present invention provides the deformation buffering space of the cowl metal plate and the front cabin by causing the relative misalignment collapse of the first support bracket 11 and the second support bracket 12. In order to achieve the above object, the front wall sheet metal connecting bracket 10 may be disposed such that the end portion of the first support bracket 11 covers the outer surface of the end portion of the second support bracket 12. In addition, the first support frame 11 and the second support frame 12 are not limited to being riveted by the aluminum rivets 14, for example, they may be fixed by other aluminum or fasteners with relatively low shearing strength, or connected by welding with relatively low connecting strength, so that the connection fails and collapses under the action of a predetermined impact.

In order to facilitate formation of other crush structures on the first support bracket 11 and the second support bracket 12, so that the first support bracket 11 and the second support bracket 12 are easily crushed and deformed in the event of a collision, and to facilitate manufacture into a box-shaped bracket, the first support bracket 11 and the second support bracket 12 may be formed by butt-joining different parts, respectively. Specifically, referring to fig. 2, the first support frame 11 includes a first side support plate 11a and a second side support plate 11b that are butted (e.g., welded) to each other in the axial direction of the instrument panel cross member 20; the second support bracket 12 includes a third side support plate 12a and a fourth side support plate 12b which are butted (e.g., welded) to each other in the axial direction of the dash cross-member 20. Wherein the first side support plate 11a and the third side support plate 12a are connected by a fastener such as the aforementioned aluminum rivet 14, and the second side support plate 11b and the fourth side support plate 12b are connected by a fastener such as the aforementioned aluminum rivet 14, whereby the fastener can be cut to cause a dislocation collapse under a predetermined impact.

side support plates

12a and 12b and be inwardly recessed. Compared with the traditional through hole punching structural feature, the weakened crumple groove 12c can play a role in locally weakening and guiding crumple on the premise of not influencing the strength of the whole structure.

Further, the side walls of the third side support plate 12a and the fourth side support plate 12b of the second support frame 12 may be formed with rhombic weakening grooves 12d penetrating in the thickness direction. Since the rhombic weakening grooves 12d have small ends and large middle portions and have unstable characteristics, the third side support plate 12a and the fourth side support plate 12b can be guided to collapse toward the middle portion when a collision occurs, and the plate body structure is prevented from being too strong and rigid to be collapsed and intruding into the cabin to injure passengers.

To facilitate the connection of the front wall metal plate of the vehicle body, one end of the second support frame 12, which is far away from the first support frame 11, may be connected with a front wall metal plate support plate 13, and the front wall metal plate support plate 13 has a welding flange 131 connected to the second support frame 12. From this, can adapt to different motorcycle types through setting up the welding turn-ups 131 of different length, avoid enclosing the different unable commonality of panel beating connecting support 10 that leads to before leading to because of enclosing the panel beating clearance before the different instrument board crossbeams of motorcycle type and automobile body, adapt to the motorcycle type of different distances in a flexible way, do benefit to header board crossbeam bracket component universalization. Wherein, enclose before can be formed with bolt mounting hole 132 on the panel beating backup pad 13 and be used for with the fixed card hole of 15 joint of clearance adjustment nut, the nut can be welded to one side of bolt mounting hole 132 towards second support frame 12 to enclose the panel beating before can passing through the fixed automobile body of bolt.

Thus, as shown in fig. 5, the dash panel connecting bracket 10 of the present invention is formed to have a triple crash box. The welding structure of the front wall sheet metal support plate 13 and the second support frame 12 forms a first-order energy absorption box, and the collapsing space is 2/3 of the size of the welding flange 131; the collapse structure (weakening collapse groove 12c, rhombic weakening groove 12d and the like) formed on the first support frame 12 is formed into a second-order energy-absorbing box, and the energy-absorbing box is guided to collapse by utilizing the rhombic unstable characteristic (as shown by a dotted line in fig. 8); the shearing dislocation collapse of the first support frame 11 and the second support frame 12 is formed into a three-order energy absorption box. The second support frame 12 may have a bent portion, so that on one hand, the front wall sheet metal support plate 13 and the first support frame 11 are relatively dislocated in the axial direction of the automobile instrument panel 20, which facilitates the arrangement of the bottom support frame 30 and the upper steering mechanism thereof described later; on the other hand, the second support frame 12 can be bent and collapsed along the bent portion in case of collision.
