The breakable grooves 322 are formed by inwardly recessing the surfaces of the left and right sides of the bracket middle plate 32 so that the thickness of the bracket middle plate 32 at the breakable grooves 322 is smaller than the thickness of the bracket middle plate 32 at other positions. In the event of a serious collision accident, the knees of the driver easily hit the bracket lower plate 33 from obliquely above the column cover bracket 3, the bracket lower plate 33 is located at a relatively large distance from the breakable groove 322, and the column cover bracket 3 is broken at the breakable groove 322 when the bending stress applied to the breakable groove 322 reaches the breaking limit.
As shown in fig. 2 to 3, the steering column shroud bracket mounting structure according to the embodiment of the present invention further includes a screw seat 5 having a quadrangular frustum pyramid shape, an upper surface of the screw seat 5 becomes smaller, and a side length of a lower surface is larger. The lower portion of the screw holder 5 is provided with screw holder mounting grooves 51, and the screw holder mounting grooves 51 are wound on four side surfaces of the screw holder 5 in parallel with the bottom edge of the screw holder 5. Correspondingly, a square hole 331 is formed in the center of the upper surface of the bracket lower plate 33, and the side length of the square hole 331 is equal to the side length of the cross section of the screw seat 5 in the screw seat mounting groove 51. When mounting, the upper portion of the screw holder 5 is passed upward through the square hole 331 from the bottom surface of the bracket lower plate 33, and the screw holder 5 is connected to the lower plate 33 with the screw holder mounting groove 51 fitted to the square hole 331.
It should be noted that four edges of the side wall of the screw seat 5 may be set to be a rounded corner structure, and four corners of the square hole 331 may also be set to be a matched rounded corner structure. Thus, the contact area between the square hole 331 and the screw seat mounting groove 51 can be increased, the abrasion of four edges of the screw seat 5 when the screw seat 5 is mounted is reduced, and the screw seat 5 can be more easily mounted in the square hole 331.
In some embodiments of the present application, as shown in fig. 4, the column lower shroud 2 may be provided with a recess 21, the recess 21 may have a circular cross-sectional shape, a bottom plane is inclined with respect to an opening plane, and a junction of the recess 21 and the outer surface of the column lower shroud 2 is provided with a rounded corner. When the column lower shield 2 is mounted below the steering column 1, the bottom plane of the recess 21 is parallel to the axis of the steering column 1, and a through hole 22 is provided at the center position of the bottom plane of the recess 21. Correspondingly, a second threaded hole 52 is formed in the center of the bottom surface of the screw seat 5, and the diameter of the second threaded hole 52 is equal to that of the through hole 22. During installation, the lower steering column shield 2 and the upper steering column shield 7 are installed together, the second threaded holes 52 can be overlapped with the through holes 22, and then the second screws 6 penetrate through the through holes 22 to be matched with the second threaded holes 52, so that the lower steering column shield 2 is connected with the lower steering column shield support 3. This connection structure is simple, easily installs and dismantles, makes to be connected closely between steering column lower shield 2 and the steering column shield support 3, and difficult appearance is not hard up.
In some embodiments of the present application, as shown in fig. 4, the side wall of the recess 21 may be provided with a weakening hole 23. When a vehicle has a frontal collision accident, the knees of a driver easily impact the lower steering column shield 2 at a downward inclined angle, the structure of the joint of the lower steering column shield 2 and the steering column shield support 3 is complex, and the weakened holes 23 can reduce the strength of the joint of the lower steering column shield 2 and the steering column shield support 3, so that the lower steering column shield 2 can be sufficiently crushed to absorb the energy of the impact.
As shown in fig. 2 to 3, a bracket mounting base 11 is attached to a side surface of the steering column 1 close to the steering column lower shroud 2, a lower end surface of the bracket mounting base 11 connected to a bracket upper plate 31 is a plane parallel to an axis of the steering column 1, and a width of the plane is larger than a width of the bracket upper plate 31, and a length of a lower end surface of the bracket mounting base 11 is larger than a length of the bracket upper plate 31, so that an upper surface of the bracket upper plate 31 can be closely attached to the lower end surface of the bracket mounting base 11.
It is to be understood that, as shown in fig. 5 and 7, in order to fix the bracket upper plate 31 to the bracket mounting base 11, a first screw hole 111 may be provided on a lower end surface of the bracket mounting base 11, the first screw hole 111 being located close to the upper portion of the steering column 1. Correspondingly, the bracket upper plate 31 may be provided with an upper plate mounting hole 313, and the diameter of the mounting hole 313 may be equal to the diameter of the first screw hole 111. The first screw 4 may be fitted through the upper plate mounting hole 313 and the first screw hole 111 to couple the steering column 1 with the steering column shroud 3.
In some embodiments of the present application, as shown in fig. 5, two upper plate mounting posts 311 may be disposed on the bracket upper plate 31, and the upper plate mounting posts 311 protrude upward from the upper surface of the bracket upper plate 31. Correspondingly, two positioning holes 112 may be disposed on the lower end surface of the bracket mounting table 11, the distance between the two positioning holes 112 is equal to the distance between the two upper plate mounting posts 311, and the diameter of the two positioning holes 112 is equal to the diameter of the upper plate mounting posts 311. When the bracket upper plate 31 and the bracket mounting table 11 are mounted, the two upper plate mounting posts 311 may be inserted into the two corresponding positioning holes 112, at this time, the mounting holes 313 coincide with the positions of the first threaded holes 111, and then the first screws 4 may be inserted through the upper plate mounting holes 313 and screwed into the first threaded holes 111.
It should be noted that the fitting relationship between the two upper plate mounting posts 311 and the two positioning holes 112 may be a transition fitting, and a chamfer structure may be disposed between the top surfaces and the cylindrical surfaces of the two upper plate mounting posts 311, so that the two upper plate mounting posts 311 can be easily inserted into the two corresponding positioning holes 112. The distance between the upper surfaces of the two upper plate mounting posts 311 and the upper surface of the bracket upper plate 31 is smaller than the depth of the two positioning holes 112, so that the lower surface of the bracket mounting table 11 can be attached to the upper surface of the bracket upper plate 31. The bottom edges of the two upper board mounting posts 311 may be provided with grooves, so that the two upper board mounting posts 311 may be connected with the bracket upper board 31 by welding.
In some embodiments of the present application, as shown in FIG. 2, the bracket upper plate 31 is recessed downwardly at a location between two upper plate mounting posts 311, forming an upper plate stiffener 312. The middle part of the upper plate reinforcing rib 312 is an elongated rectangle, both ends are semicircular, the depth of the downward recess gradually increases from the edge to the center, the length direction of the downward recess is the same as the length direction of the bracket upper plate 31, and the deformation amount of the deepest part of the downward recess is about one fourth of the thickness of the bracket upper plate 31.
In some embodiments of the present application, as shown in FIG. 4, the upper portion of the bracket middle plate 32 may be provided with a middle plate stiffener 321. The middle plate reinforcing ribs 321 extend from the junction of the bracket middle plate 32 and the bracket upper plate 31 in the length direction of the bracket middle plate 32, and the length of the middle plate reinforcing ribs 321 is about half of the length of the bracket middle plate 32. The middle of the middle panel stiffener 321 is an elongated rectangle that intersects the breakable grooves 322 perpendicularly. Both ends of the middle plate reinforcing rib 321 are semicircular, and the depth of the downward recess gradually increases from the edge to the center. The middle plate reinforcing ribs 321 can increase the strength of the bracket middle plate 32 in the vertical direction, so that the requirement of connecting the steering column 1 and the steering column lower shield 2 can be met, and the bending deformation cannot occur in the normal use process of the vehicle. When the column shroud bracket 3 is impacted, the bending stress generated by the impact is concentrated on the breakable groove 322, so that the column shroud bracket 3 is broken at the breakable groove 322, and the middle plate reinforcing rib 321 does not affect the strength at the breakable groove 322.
The embodiment of the application also provides a vehicle which comprises the steering column shield support mounting structure. In this type of vehicle, the driver's leg airbag is not provided, and the knees of the driver hit the column lower cover 2 in the event of a vehicle collision accident. When the column lower cover 2 is broken by the force of the impact, the knees of the driver continue to move toward the steering column 1 and collide with the lower portion of the column cover bracket 3. The column shroud bracket 3 is instantaneously subjected to a large bending stress and is broken at the breakable groove 322 to absorb the capability of the impact generation, reducing the injury of the driver's knees.
It should be noted that the steering column shroud bracket mounting structure provided in the embodiment of the present application may be assembled in the following steps.
First, the upper portion of the screw holder 5 is passed upward through the square hole 331 from the bottom surface of the bracket lower plate 33, and the screw holder mounting groove 51 is fitted into the square hole 331.
In the second step, two upper plate mounting posts 311 are mounted in the corresponding two positioning holes 112, and the first screws 4 are inserted through the upper plate mounting holes 313 and screwed into the first threaded holes 111.
And a third step of mounting the column lower shield 2 under the steering column 1 by the mounting structure of the edges of the column lower shield 2 and the column upper shield 7.
And a fourth step of connecting the column lower cover 2 to the column cover bracket 3 by making the through hole 22 on the bottom plane of the recess 21 opposite to the second screw hole 52 and fitting the second screw 6 through the through hole 22 to the second screw hole 52.
It should be noted that, in the first step, the bracket lower plate 33 can be fixed by means of a tool, so as to avoid deformation or fracture of the connection position between the bracket lower plate 33 and the bracket middle plate 32 caused by an excessive pushing force applied by the screw seat 5. In the fourth step, the torque for rotating the second screw 6 is not excessively large, so that the steering column lower shield 2 is prevented from being deformed due to the excessively large torque.
To sum up, this application embodiment provides a steering column guard shield support mounting structure, connects steering column 1 and steering column lower shield 2 through steering column guard shield support 3. The structure in which the two upper plate mounting posts 311 are inserted into the corresponding two positioning holes 112 can preliminarily fix the relative position between the steering column shield support 3 and the steering column 1, so that the upper plate mounting holes 313 can coincide with the first threaded holes 111, and the mounting accuracy between the support upper plate 31 and the support mounting table 11 is ensured. The connection structure of the first screw 4 and the first threaded hole 111 and the connection structure of the second screw 6 and the second threaded hole 52 are simple, so that the steering column shield support 3 is tightly connected between the steering column 1 and the steering column lower shield 2, and the installation and the disassembly are easy. The steering column shield support 3 is provided with the middle plate reinforcing rib 321 and the upper plate reinforcing rib 312, which can improve the strength of the steering column shield support mounting structure without affecting the strength of the breakable groove 322. When the driver's knees collide with the column lower cover 2 at a high speed and hit the column cover bracket 3 during a vehicle collision, the column cover bracket 3 is broken at the breakable groove 322, and energy generated by the collision is partially absorbed, thereby protecting the knees of the driver. In addition, the steering column shield support 3 is made of a plastic material, can be broken when impacted, is low in production cost and has smaller weight, and the light weight of the whole vehicle is favorably realized.
The embodiment of the application provides a vehicle including above-mentioned steering column guard support mounting structure. As an example, the vehicle is not equipped with a driver knee airbag. When the vehicle is in serious collision, the cabin is deformed, the safety space of a driver is reduced, the knee of the driver can impact the lower steering column shield 2 at a larger speed and cause the lower steering column shield 2 to be cracked, the knee of the driver penetrates through the lower steering column shield 2 to collide with the lower part of the steering column shield support 3, at the moment, the breakable groove 322 is subjected to larger bending stress, the breakable groove 322 is broken due to stress and absorbs the collision energy, a larger movable space is provided for the knee of the driver, and the knee of the driver is protected.
In addition, the stress limit of the breakable groove 322 in the embodiment of the present application is 300-800N, and the specific value can be calculated according to the test, so as to better protect the knee of the driver. The breakable grooves 322 are formed by inward depressions of the surfaces of the left and right sides of the middle plate 32 of the bracket, and the depth and width of the depressions can be adjusted according to the requirement of the stress limit of the breakable grooves 322. The size of the weakened hole 23 in the side wall of the recess 21 can be adjusted according to the effect of the breakage of the column lower cover 2, and the injury of the driver's knees by the fragments of the column lower cover 2 can be avoided.
