According to the drawings of fig. 1 to 3, the invention provides a steering column platformization fixing structure, which comprises a main cross beam 1, a front connecting support 2, an upper support 3, a front connecting lining plate 4, a reinforcing support 5 and a lower support 6, wherein a groove 31 is formed in the upper support 3, the main cross beam 1 is lapped in the groove 31, the front connecting support 2 is positioned above the upper support 3, one end of the front connecting support 2 is connected with the side wall of the main cross beam 1, and the front connecting lining plate 4 connects one end of the upper support 3 with the other end of the front connecting support 2. Preceding connection support 2, preceding connection welt 4, upper bracket 3 and main beam 1 form a box-packed closed cavity jointly, and when implementing, each part links together, forms a whole, and the reinforcing intensity to the fixed and required intensity that turns to of better satisfied steering column.

One end of the reinforcing bracket 5 is lapped with the side wall of the main beam 1, and the other end of the reinforcing bracket is connected with one end of the upper bracket 3 far away from the front connecting lining plate 4; the reinforcing bracket 5 and the front connecting bracket 2 can fix the main beam 1 in the groove 31; the lower bracket 6 is arranged below one end of the upper bracket 3 close to the front connecting lining plate 4 and is used for connecting with other parts of the vehicle body.

Further, the main beam 1 has three postures of high, medium, and low, and the front connecting bracket 2, the lower bracket 6, and the main beam 1 can be commonly used for the three postures of the main beam 1.

When the main beam 1 is in a high posture, two ends of the upper bracket 3 are upwardly deviated, and the length of the front connecting lining plate 4 and the length of the reinforcing bracket 5 are minimum; when the main beam 1 is in a low posture, two ends of the upper bracket 3 are deviated downwards, and the length of the front connecting lining plate 4 and the length of the reinforcing bracket 5 reach the maximum; when the main beam 1 is in the middle posture, the adjustment ranges of the upper bracket 3, the front connection liner 4 and the reinforcement bracket 5 are between the high posture and the low posture.

In the implementation, the front connecting support 2, the lower support 6 and the main beam 1 are universal to all vehicle types of the same platform without any change in order to save cost, so that the front connecting support can be produced in batch; the other front connection lining plate 4, the reinforcement bracket 5 and the upper bracket 3 need to be changed according to three postures of the main beam 1, as shown in fig. 4 and 5, from top to bottom, the three postures are divided into a high posture, a middle posture and a low posture of the main beam 1, wherein the middle posture and the low posture of the main beam 1 are approximately overlapped, the lap joint angle of the upper bracket 3 and the main beam 1 is deviated, if the installation connection needs to be met, the length of the front connection lining plate 4 is gradually lengthened from the high posture to the low posture so as to be connected with the upper bracket 3, and the reinforcement bracket 5 is also gradually lengthened from the high posture to the low posture so as to adapt to the change of the upper bracket 3.

Further, the middle attitude of the main cross member 1 is close to the low attitude thereof, and the height difference between the high-attitude position and the low-attitude position of the main cross member 1 is 30mm, as shown in fig. 6, when the high attitude of the main cross member 1 is lowered by 30mm downward, the three attitudes of the main cross member 1 coincide with each other, but as can also be seen from fig. 6 and 7, even if the main cross member 1 coincides, the positions or heights of the upper brackets 3 in the three attitudes do not coincide, resulting in a dimensional change required for the front connection pad 4 and the reinforcing brackets 5 directly connected to the upper brackets 3. The overlapped part comprises the lower bracket 6 and the front connecting bracket 2 besides the main beam 1, so that the front connecting bracket 2, the lower bracket 6 and the main beam 1 are commonly used for series of vehicle types with the same platform.

Further, as shown in fig. 8, the upper bracket 3 is provided with welding surfaces 32 at both sides, the front connecting bracket 2 is also provided with welding surfaces 32 at both sides, and the two welding surfaces 32 are connected by welding. The main body of the closed cavity built by the upper bracket 3 and the front connecting bracket 2 is ensured to be stable.

Still further, the width and length of the welding surface 32 are kept uniform in the three postures in which the main beam 1 is located at different positions. Because the front connecting bracket 2 is of a general structure, the welding surface 32 of the upper bracket 3 directly connected with the front connecting bracket 2 also needs to be treated in a general way, so that the upper bracket 3 can be stably welded with the front connecting bracket 2 no matter the upper bracket is positioned in different postures.

Further, as shown in fig. 9, one end of the front connection lining plate 4 near the front connection bracket 2 is provided with a bracket connection surface 41, and the bracket connection surface 41 is connected with the front connection bracket 2 through a bolt. In practice, the bolts are connected in at least two, so as to ensure that the position of the front connecting lining plate 4 is fixed.

Still further, as shown in fig. 2, one end of the front connecting lining plate 4 close to the front connecting bracket 2 is provided with a bent positioning block 43, and the positioning block 43 is used for buckling the front connecting bracket 2 for prepositioning.

Still further, a vehicle body connecting surface 42 is further arranged on the front connecting lining plate 4, the vehicle body connecting surface 42 and the bracket connecting surface 41 are not coplanar, and the vehicle body connecting surface 42 and the bracket connecting surface 41 are connected through an arc-shaped curved surface. Two fixed points are not coplane on preceding linking bridge 2 and preceding connection welt 4, require to reduce to the boundary shaping (enclose the sheet metal component before the automobile body and be the curved surface, the fixed point is separately and install the face section difference and more do benefit to the shaping of arc sheet metal), increase fixed point interval, arrange accelerator pedal and brake pedal mounting box in fixed point both sides, enclose sheet metal strength and rigidity before increasing here to enclose fixed point rigidity and intensity before making and be higher, as shown in fig. 10.

Further, as shown again in fig. 9, the end of the vehicle body connection surface 42 remote from the bracket connection surface 41 is connected to the upper bracket 3, and the length of the vehicle body connection surface 42 varies depending on the three postures of the main cross member 1. The position and the angle of the upper bracket 3 in the three postures can be changed, because the front connecting bracket 2 is of a general structure, the bracket connecting surface 41 directly connected with the front connecting bracket 2 is of a general structure, and the length of the vehicle body connecting surface 42 directly connected with the upper bracket 3 is gradually increased from a high posture to a low posture so as to be better connected with the upper bracket 3.

According to another aspect of the invention, a vehicle is further provided, which comprises the steering column platformized fixing structure of any embodiment, and can meet matching requirements of the same vehicle type.

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.
