Description
Technical Field
The invention relates to the technical field of vehicle parts, in particular to a knee protection structure for a driver of a commercial vehicle instrument panel.
Background
Knee collision of an automobile instrument panel is an important research content in the field of passive safety of automobile interior parts, national standards GB 11551 and C _ NCAP make relevant requirements on knee collision of dummy of passenger vehicles, but corresponding requirements are not provided on commercial vehicles at present, and knee protection of passengers is hardly considered in design of most commercial vehicles on the market.
In the conventional design of the existing instrument panel, one part of a mounting bracket of the instrument panel is connected with a tubular beam of a cross beam (CCB) of an automobile, and the other part of the mounting bracket is connected with a guard plate.
Therefore, with reference to the requirements of C _ NCAP on collision and injury of knees of dummy in passenger car, and with reference to the structural characteristics of instrument panel of commercial vehicle and sitting posture characteristics of passengers, there is an urgent need to develop a knee protection structure for driver suitable for commercial instrument panel.
Disclosure of Invention
The invention aims to provide a knee protection structure for a driver of a commercial vehicle instrument panel, aiming at overcoming the defects of the prior art, and solving the problem that the leg injury of the driver in the collision process cannot be effectively reduced due to the lack of knee protection design of the driver side structure of the commercial vehicle instrument panel.
In order to achieve the purpose, the knee protection structure for the driver of the instrument panel of the commercial vehicle comprises a CCB tubular beam and also comprises two knee protection plates corresponding to the knees of the driver on the instrument panel side, wherein a mounting bracket is mounted on the back surface of each knee protection plate, each mounting bracket is of a V-shaped structure, each mounting bracket is fixedly mounted on the back surface of each knee protection plate through the outside of one end, a mounting seat is arranged on the inner side of the other end of each mounting bracket, and the CCB tubular beam is fixedly mounted on the mounting bracket through the mounting seats.
Preferably, the knee guard is a curved structure, and an outward convex portion of the knee guard faces the knees of the driver.
Preferably, the V-shaped structure of the mounting bracket opens upwardly.
Preferably, an elastic support plate is arranged in the mounting bracket, and two ends of the elastic support plate respectively abut against the inner walls of two ends of the V-shaped structure of the mounting bracket.
Preferably, the mounting block is mounted on the mounting bracket by at least two bolts.
Preferably, the bolts are arranged horizontally.
Compared with the prior art, the invention has the following advantages:
1. the knee protection device has an obvious effect on the knee protection of the driver side of the instrument panel of the commercial vehicle;
2. the obtained thigh force displacement curve is ideal, the average fluctuation of the counter force is small, and the energy absorption effect is excellent;
3. the structural design parameters are simple and easy to adjust, the required knee impact protection effect can be adjusted according to the design requirements, and the application expansibility is strong.

Detailed Description
The invention is described in further detail below with reference to the figures and the specific embodiments.
As shown in fig. 1 and 2, the knee protection structure for a driver on an instrument panel of a commercial vehicle comprises a CCB tubular beam 1 and further comprises two knee protection plates 2 corresponding to knees of the driver on the instrument panel side, a mounting bracket 3 is mounted on the back of each knee protection plate 2, as shown in fig. 3, 4 and 5, each mounting bracket 3 is of a V-shaped structure, each mounting bracket 3 is fixedly mounted on the back of each knee protection plate 2 through the outside of one end, a mounting seat 4 is arranged on the inner side of the other end of each mounting bracket 3, and the CCB tubular beam 1 is fixedly mounted on each mounting bracket 3 through the corresponding mounting seat 4.
In this embodiment, the knee guard 2 is a curved structure, the outward protruding part of which faces the knee of the driver, and the V-shaped structure of the mounting bracket 3 opens upward.
As shown in fig. 3, 4 and 5, the mounting bracket 3 is provided with an elastic support plate 5 therein, and two ends of the elastic support plate respectively abut against the inner walls of two ends of the V-shaped structure of the mounting bracket 3.
In this embodiment, the mounting seat 4 is installed on the mounting bracket 3 through two bolts 6, and the two bolts 6 are horizontally arranged, so that the force can be better applied.
When the automobile mounting bracket is used, in the collision process of an automobile, the knees of a driver impact the surface of the knee protection plate 2, the structural strength design of the back of the knee protection plate 2 influences the protection effect of the legs of the driver, so that the mounting bracket 3 is required to be not too strong in structure and can be well collapsed, deformed and energy-absorbed, otherwise, the thigh force easily exceeds the force value defined by the design requirement and does not meet the requirement; and not too weak to absorb sufficient energy within the designed depth of intrusion.
In this embodiment, only the structural strength of the mounting bracket 3 and the elasticity of the elastic support plate 5 need to be adjusted to achieve the required knee-collision protection effect, and the design parameters are concise and easy to adjust.
The knee crash animation process and the protection structure deformation in the use process of the invention are shown in figure 6, and the knee crash animation process and the protection structure deformation have obvious effect on protecting the knee at the driver side of the instrument panel of the commercial vehicle.
The knee protection structure for the driver of the instrument panel of the commercial vehicle has an obvious effect on knee protection of the driver side of the instrument panel of the commercial vehicle; the obtained thigh force displacement curve is ideal, the average fluctuation of the counter force is small, and the energy absorption effect is excellent; the structural design parameters are simple and easy to adjust, the required knee impact protection effect can be adjusted according to the design requirements, and the application expansibility is strong.
