Detailed Description
The present invention is described in further detail below with reference to specific embodiments and the attached drawings. It is intended that the present invention not be limited to the particular embodiments disclosed, but that the present invention will include all embodiments falling within the scope of the appended claims.
Referring to fig. 1 and 4, the utility model provides an aluminum threshold additional strengthening of electric motor car, include:
the steel plate spring comprises an aluminum reinforcing piece 1, an L-shaped bracket 2, a spring 3 and a long steel plate 4;
There are generally two solutions to reduce the intrusion of the vehicle body into the battery pack in the prior art: one is to add a large number of reinforcements inside the rocker, and the other is to integrate the inner and outer rocker panels and the internal reinforcements into a stronger aluminum structure.
The first scheme is applicable to the planking in traditional steel threshold, can directly produce at current production line, nevertheless owing to introduced a large amount of reinforcements, can the whole car weight of greatly increased. As shown in fig. 2.
The second solution integrates the threshold entirely in an aluminum structure, as shown in fig. 3. Because of the large matching surface when connecting with other vehicle body parts (such as front and rear longitudinal beams, front and rear floors), a large number of special steel-aluminum connecting modes such as FDS, SPR and the like are required. The traditional welding production line can not meet the connection requirement, and needs to be transformed on a large scale and even a production line is newly added, so that huge investment is generated. And the threshold is integrated into aluminium totally, and no matter be the cost of bicycle material or connect the cost all very high.
The utility model provides an aluminium threshold additional strengthening of electric motor car when keeping traditional steel threshold interior planking unchangeable, replaces the reinforcement of inside for aluminium structure. L type support 2 is equipped with in aluminium threshold additional strengthening's inside, and optionally, L type support 2 is the steel support, and in the connection process with the threshold inner panel, can be with L type support 2 and threshold spot welding prepositioning earlier, then with aluminium threshold additional strengthening fixed to the automobile body on. Because the cavity that the outer panel formed in the threshold was the uniform cross-section, and extruded aluminium self process characteristics has decided also the uniform cross-section, consequently this structure can with the interior planking of threshold from the front to back perfect laminating, and be inside the threshold cavity completely, just can not bring workshop steel aluminium to connect the demand yet.
The utility model discloses a to the side protection of wide battery, through on traditional steel threshold structure basis to minimalization's change realizes satisfying the performance, reducing the car weight, and to the minimum effect of workshop influence. Meanwhile, the whole vehicle framework can be expanded to narrow battery protection, the extruded aluminum section can be directly reduced, the interface with the vehicle body is not changed, and therefore the flexible design of the vehicle body is achieved.
In one embodiment, the upper and lower surfaces of the aluminum reinforcement 1 are mounted to the L-shaped bracket 2 by means of blind rivet nuts 6.
Because the cavity of the aluminum reinforcement is long, if the conventional bolt connection is used, a nut needs to be preassembled inside the reinforcement, and the exposed part of the external bolt interferes with the threshold based on the current cross section of the threshold. And secondly, a rivet nut is adopted, the nut does not need to be pre-installed in the aluminum reinforcement, the rivet nut directly penetrates through the support and the reinforcement, the support can be fixed after the rivet center is broken, and the external protruding part is very small and cannot interfere with the threshold. The single side of the rivet nut can be reached, and the fastening purpose can be realized.
In one of the embodiments, the elongated steel plate 4 is mounted inside the aluminum reinforcement 1 by means of a blind rivet nut 6. Because the cavity of the aluminum reinforcement is long, if the conventional bolt connection is used, a nut needs to be preassembled inside the reinforcement, and the exposed part of the external bolt interferes with the threshold based on the current cross section of the threshold. And secondly, a rivet nut is adopted, the nut does not need to be pre-installed in the aluminum reinforcement, the rivet nut directly penetrates through the support and the reinforcement, the support can be fixed after the rivet center is broken, and the external protruding part is very small and cannot interfere with the threshold. The single side of the rivet nut can be reached, and the fastening purpose can be realized.
In one embodiment, the spring 3 is a U-shaped spring. The U-shaped spring passes through a rectangular hole in the side wall of the threshold 1, and the U-shaped groove is clamped at the edge of the rectangular hole. The U-shaped spring is provided with internal threads, the internal threads are used for fastening the bolt 13, and the position of the internal threads can be adjusted by adjusting the position of the U-shaped spring, so that the assembly of the doorsill and the lower vehicle body is facilitated.
Referring to fig. 5, the utility model also provides a lower automobile body of electric motor car, including welding lower automobile body front deck 9, forebay 10, back floor 11 and threshold inner panel 8 in the automobile body main part down, still include above-mentioned arbitrary the aluminium threshold additional strengthening of electric motor car, aluminium threshold additional strengthening is connected with threshold inner panel 8.
And a lower vehicle body front cabin 9, a front floor 10, a rear floor 11 and a threshold inner plate 8 are welded behind a lower vehicle body main body, and finally the aluminum threshold reinforcing structure 7 is pushed onto a main line to be connected with the threshold inner plate 8 to form a complete lower vehicle body.
The utility model discloses a to the side protection of wide battery, through on traditional steel threshold structure basis to minimalization's change realizes satisfying the performance, reducing the car weight, and to the minimum effect of workshop influence. Meanwhile, the whole vehicle framework can be expanded to narrow battery protection, the extruded aluminum section can be directly reduced, the interface with the vehicle body is not changed, and therefore the flexible design of the vehicle body is achieved.
In one embodiment, the L-shaped bracket 2 is electrically welded to the rocker inner panel 8. In fig. 6, in the process of feeding the aluminum reinforcement structure to the rocker inner panel 8, the L-shaped bracket 2 is first connected to the rocker inner panel 8 by spot welding, and thus, a pre-positioning function is achieved.
Referring to fig. 6, in one of the embodiments, the aluminum rocker reinforcement is fixed to the lower vehicle body by bolts 13 through the springs 3. Bolts 13 pass through the U-shaped springs 3 to fix the aluminum rocker reinforcement to the vehicle body. The U-shaped spring is provided with internal threads, the internal threads are used for fastening the bolt 13, and the position of the internal threads can be adjusted by adjusting the position of the U-shaped spring, so that the assembly of the doorsill and the lower vehicle body is facilitated.
Optionally, the mounting bracket 5 is connected to the lower body by electric welding, further fixing the aluminum reinforcement to the body.
Optionally, the lower surface L-shaped bracket 2 and the sill inner panel 8 are connected by electric welding through a turndown.
The utility model also provides an automobile, including above-mentioned arbitrary lower automobile body of electric motor car.
What has been described above is merely the principles and preferred embodiments of the present invention.
