As shown in the figure3. In one possible embodiment, shown in fig. 7, the crush structure 212 is a failure chamfer 2121, and for the crush structure 212 to work when the impact force is greater than 2KN, the chamfer angle of the failure chamfer 2121 is set to 130 °, a shown in fig. 3 is the chamfer angle of the failure chamfer 2121, further, the width of the buckle 11 from the first step 113 to the second step 114 is gradually increased to form an inclination angle, d shown in fig. 3 is the width of the buckle 11, d is the width of the buckle 112D is the width of the first step 113 and also the width of the portion of the crush structure 212 that fails at the first step 1132Has a value of 0.7mm, d in FIG. 43Width of the portion of the crush structure 212 that fails when abutting the secondary step 114, d3The value of (1.3 mm) is larger than the width of the first step 113, as shown in fig. 7, the buckle 11 is further provided with a weakening groove 115, the weakening groove 115 is arranged on the side edge of the first chuck 111 and the second chuck 112, the weakening groove 115 is in a strip shape from top to bottom, and the length of the weakening groove 115 is d4，d4Has a value of 29mm and the width d of the weakening groove 1155，d5The value of (A) is 1.2 mm.
The setting mode has the advantages that: in order to ensure that the crumple structure 212 is crumpled when the crumple structure 212 is impacted by 2KN, the crumple structure 212 is arranged to be a failure chamfer 2121, the angle of the failure chamfer 2121 is made to be 130 degrees as required, the crumple structure 212 has much smaller force bearing capacity than the conventional force bearing capacity, when the impact force is larger than 2KN, the crumple structure 212 is broken at the first-stage step 113, so that limit failure is ensured, meanwhile, in order to ensure that the crumple structure 212 can absorb energy when the buckle 11 moves downwards, the width d of the buckle 11 is gradually increased from the first-stage step 113 to the second-stage step 114, an inclination angle is formed, and the crumple structure 212 and the first-stage step 113 at the position of the first-stage step 113 are interfered by 0.7mm (d)2) When the instrument panel cover plate 1 is impacted, the buckle 11 moves downwards, the secondary step 114 moves to the position of the collapse structure 212 gradually and abuts against the collapse structure 212, and the total width of the part of the collapse structure 212 which fails and is broken off and the part which is worn off is 1.3mm (d)3) During the moving process of the buckle 11, the crush structure 212 rubs against the side of the buckle 11, and the buckle 11 will be crushedThe structure 212 is worn to absorb a large amount of energy, which can effectively reduce the impact energy transmitted to the leg of the occupant until the secondary step 114 of the buckle 11 abuts on the crush structure 212 and the buckle 11 stops moving downward.
When the instrument panel is impacted by an occupant, the crumple structure 212 is crumpled at the first-stage step 113 and the limit at the first-stage step 113 is disabled, along with the downward movement of the buckle 11, the crumple structure 212 rubs with the buckle 11, the crumple structure 212 is worn by the buckle 11, and then impact energy is absorbed, so as to ensure that the crumple structure 212 is crumpled at the first-stage step 113, generally, the width of the first-stage step 113 is set to be smaller, so that the contact area of the crumple structure 212 and the first-stage step 113 is smaller, the acting force of the first-stage step 113 to the unit area of the crumple structure 212 is larger, so that the crumple structure 212 is facilitated, and when the second-stage step 114 on the buckle 11 moves to the crumple structure 212, if the width of the second-stage step 114 is also smaller, the contact area of the crumple structure 212 and the second-stage step 114 is also smaller, so that the acting force of the second-stage step 114 to the unit area of the crumple structure 212 is larger, it is likely that the crumple structure 212 cannot be successfully abutted against the second-level step 114, but continues to be crumpled at the second-level step 114, and the limit at the second-level step 114 fails, so that the buckle 11 continues to move downwards, and the instrument panel is damaged, therefore, the width of the second-level step 114 is set to be larger than the width of the first-level step 113, so that the acting force of the second-level step 114 on the unit area of the crumple structure 212 is small, the second-level step 114 can be stably abutted against the second-level step 114, and the damage of the instrument panel caused by the limit failure at the second-level step 114 is prevented.
In addition, in order to ensure that the buckle 11 can be smoothly deformed so as to enable the second chuck 112 to abut against the limiting rib 211, two weakening grooves 115 with the thickness of 1.2mm × 29mm are formed in the buckle 11, the weakening grooves 115 reduce the strength of the buckle 11, and further the plastic deformation of the buckle 11 in the left-right direction in fig. 3 is enhanced, so that the first chuck 111 and the second chuck 112 can be successfully abutted against the limiting rib 211, and the crumple structure 212 can be ensured to be more effective, and the situation that the crumple structure 212 and the buckle 11 are blocked and cannot smoothly abut against the second step 114 to further influence the energy absorption effect is prevented.
As shown in fig. 3, in one possible embodiment, a rubber pad (not shown) is disposed on the secondary step 114, the crush structure 212 is configured to be capable of abutting against the rubber pad after being impacted, and anti-slip protrusions (not shown) are disposed on the side portions of the buckles 11 from the primary step 113 to the secondary step 114, as shown in fig. 6, in one possible embodiment, the crush structure 212 may also be a failure groove 2122 without any limitation on the crush structure 212, and a person skilled in the art can set the crush structure 212 as needed as long as the crush structure 212 can be crushed when the instrument panel is impacted.
The setting mode has the advantages that: the rubber pad is arranged on the second-stage step 114, so that when the crumple structure 212 abuts against the second-stage step 114, the rubber pad can provide buffering for the crumple structure 212, specifically, when the impact force is large, the impact force is still large after the crumple structure 212 is crumpled, the rigid impact energy absorption of the crumple structure 212 and the second-stage step 114 is limited, and the residual impact energy is absorbed through the elastic buffering of the rubber pad, so that the injury of the instrument panel to the passengers is further prevented. Further, the lateral part of the buckle 11 from the first step 113 to the second step 114 is provided with an anti-slip protrusion, when the crumple structure 212 loses effectiveness at the first step 113, the side part of the buckle 11 rubs, and the impact energy is absorbed by the abrasion of the crumple structure 212, and when the friction force between the crumple structure 212 and the lateral part of the buckle 11 is small, the crumple structure 212 slips with the buckle 11 when the buckle 11 moves downwards, so that the energy is absorbed and reduced. In one embodiment, the crush feature 212 can be a crush chamfer 2121 or a failure groove 2122, and the one-step 113 can apply a downward force to the failure groove 2122 during an impact, thereby breaking the crush feature 212 at the failure groove 2122 and adjusting the impact force when the crush occurs by providing failure grooves 2122 with different depths.
In summary, in the instrument panel of the invention, the crumple structure is arranged on the instrument panel framework, when a passenger impacts the instrument panel cover plate, the damage of impact force to the legs of the passenger is reduced through the crumple deformation of the crumple structure, so that the protection performance of the passenger in the automobile passenger cabin to the passenger is enhanced, further, the crumple structure is arranged into the crumple chamfer, and the chamfer angle of the crumple chamfer is set according to the preset impact force, so that the crumple can take effect, the damage to the passenger is reduced, in the process of moving down the buckle, the crumple structure and the side part of the buckle are damaged after friction for absorbing energy, so that the impact energy is further absorbed, and the plastic deformation of the buckle can be enhanced through the weakening groove arranged on the buckle, so that the chuck can be successfully abutted against the crumple structure.
Finally, although the present invention is described by taking the instrument panel of an automobile as an example, it is obvious that the automobile of the present invention may be an electric automobile or a fuel automobile.
It should be noted that the above-mentioned embodiments are only used for illustrating the principle of the present invention, and are not intended to limit the protection scope of the present invention, and those skilled in the art can modify the above-mentioned structure so that the present invention can be applied to more specific application scenarios without departing from the principle of the present invention.

For example, in an alternative embodiment, the number of weakening grooves 115 may be one, two or five, and thus the number of weakening grooves 115 is not limited, and may be set by the person skilled in the art as desired without departing from the principle of the present invention, and thus fall within the scope of the present invention.
For example, in an alternative embodiment, the number of the slots 21 and the catches 11 may be one or more, and there is no limitation on the number and the arrangement positions of the catches 11 and the slots 21, and those skilled in the art can set the number and the arrangement positions as needed without departing from the principle of the present invention, and therefore, the present invention will fall into the protection scope of the present invention.
