Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of vehicles, and in particular provides an instrument panel for a vehicle and the vehicle. Background Art
[0002] The dashboard is a very unique component in a car, integrating safety, functionality, comfort and decoration. In terms of passive safety, more and more attention is paid to knee impact force.
[0003] The existing instrument panel usually consists of an instrument panel cover and an instrument panel frame, and the instrument panel cover is fixed to the instrument panel frame by buckles. Figure 1 Traditional clips consist of only a clip and a supporting rib. These clips abut the instrument panel frame, securing the instrument panel cover and frame in place through their interaction. In the event of a collision, the clip and rib remain fixed, ensuring the relative position of the instrument panel cover and frame remains constant. Energy absorption occurs through the plastic deformation or even fracture of the instrument panel frame itself. However, due to increasing attention to instrument panel rigidity in recent years and the gradual improvement of instrument panel frame strength, the instrument panel frame's inherent energy absorption capacity is limited, resulting in a higher degree of impact force being transferred to the occupant's knees, potentially causing injury.
[0004] Accordingly, there is a need in the art for a new instrument panel for a vehicle to solve the problem that the existing instrument panel has limited energy absorption when hit, thereby causing injuries to passengers. Summary of the Invention
[0005] The present invention aims to solve the above technical problem, that is, to solve the problem that the existing instrument panel has limited energy absorption when it is hit, thereby causing injuries to the occupants.
[0006] In a first aspect, the present invention provides an instrument panel for a vehicle, the instrument panel comprising an instrument panel cover and an instrument panel frame, a clip is provided on the instrument panel cover, a second clip and a first clip are provided on one side of the clip from top to bottom, and a secondary step and a primary step are provided on the other side from top to bottom; a clip gap is provided on the instrument panel frame, one side of the clip gap is a limiting rib, and the other side is a collapse structure, the instrument panel is configured so that when the instrument panel cover is normally installed on the instrument panel frame, the clip goes deep into the clip gap, the first clip abuts on the limiting rib, and the collapse structure abuts on the primary step; when the outer side of the instrument panel cover is impacted, the collapse structure collapses, and the abutment between the collapse structure and the primary step fails until the collapse structure abuts on the secondary step again, and at the same time the clip moves downward, and the second clip abuts on the limiting rib again.
[0007] In the preferred technical solution of the above-mentioned instrument panel for a vehicle, the collapse structure is a failure chamfer.
[0008] In the preferred technical solution of the above-mentioned dashboard for a vehicle, the width of the buckle gradually increases from the first step to the second step.
[0009] In the preferred technical solution of the above-mentioned instrument panel for a vehicle, the width of the secondary step is greater than the width of the primary step.
[0010] In the preferred technical solution of the above-mentioned instrument panel for a vehicle, the collapse structure is a failure groove.
[0011] In the preferred technical solution of the above-mentioned dashboard for a vehicle, a weakened groove is provided on the buckle, and the weakened groove is provided on the side of the first clamping head and the second clamping head.
[0012] In the preferred technical solution of the above-mentioned dashboard for a vehicle, a rubber pad is provided on the secondary step, and the collapse structure can abut against the rubber pad.
[0013] In the preferred technical solution of the above-mentioned dashboard for a vehicle, the side of the buckle from the first step to the second step is provided with an anti-slip protrusion.
[0014] In the preferred technical solution of the above-mentioned instrument panel for a vehicle, the angle of the failure chamfer is 110° to 170°.
[0015] The present invention also provides a vehicle, comprising the instrument panel for the vehicle according to any one of the above technical solutions.
[0016] Those skilled in the art will appreciate that the dashboard for a vehicle of the present invention includes a dashboard cover and a dashboard frame, a clip is provided on the dashboard cover, a second clip and a first clip are provided on one side of the clip from top to bottom, and a secondary step and a primary step are provided on the other side from top to bottom; a slot is provided on the dashboard frame, a limiting rib is provided on one side of the slot, and a collapse structure is provided on the other side, and the dashboard is configured so that when the dashboard cover is normally installed on the dashboard frame, the clip penetrates into the slot, the first clip abuts against the limiting rib, and the collapse structure abuts against the primary step; when the outer side of the dashboard cover is impacted, the collapse structure collapses, and the abutment between the collapse structure and the primary step fails until the collapse structure abuts against the secondary step again, and at the same time the clip moves downward, and the second clip abuts against the limiting rib again.
[0017] When the above technical solution is adopted, when the instrument panel of the present invention is normally installed, the instrument panel cover is fixed to the instrument panel frame. Specifically, the buckle of the instrument panel cover is deeply inserted into the card slot, the first card head is clamped on the limiting rib, and the collapse structure on the instrument panel frame abuts against the first step, so that the instrument panel cover is fixed to the instrument panel frame, and the relative position of the instrument panel cover and the instrument panel frame is kept fixed. When the vehicle is hit, the legs of the occupant will hit the instrument panel cover under the action of inertia. After the instrument panel cover is hit, the buckle moves downward in the card slot, and the collapse structure The collapsing structure is subjected to the downward force of the first step and absorbs most of the impact force of the legs on the instrument panel cover during the collapse process, thereby reducing the force of the instrument panel cover on the legs, thereby reducing the damage of the instrument panel to the legs when the legs hit the instrument panel. After the collapsing structure fails at the first step, the buckle continues to move downward. At this time, the collapsing structure rubs against the side of the buckle. During the friction process, the collapsing structure is worn by the buckle, further absorbing the impact energy. When the second step of the buckle abuts against the collapsing structure, the second clamp head of the buckle is clamped on the limiting rib, and the buckle stops moving.
[0018] Compared to prior art designs where the instrument panel cover is rigidly connected to the instrument panel frame, whereby when a leg strikes the instrument panel cover, the instrument panel frame itself is solely plastically deformed or fractured to cushion the impact. In contrast, when the instrument panel is impacted, the crush structure of the present invention collapses to cushion the impact of the leg, thereby reducing the irreversible deformation of the entire instrument panel frame. Post-impact repairs only require replacing the buckle and the crush structure, significantly reducing repair costs. Prior art designs often increase the strength of the instrument panel frame to minimize deformation when a leg strikes the instrument panel, significantly increasing the risk of damage to the occupant's legs. However, weakening the instrument panel frame can also lead to other issues, such as collapse and deformation. The present invention utilizes a crush structure to cushion the impact without restricting the strength of the instrument panel frame. Consequently, the strength of the instrument panel frame can be increased as needed, preventing collapse and deformation, improving the quality of the vehicle's interior, enhancing occupant protection, and enhancing vehicle safety.

[0031] Furthermore, it should be noted that, in the description of the present invention, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to mechanical connections; they may refer to direct connections, indirect connections through an intermediary, or internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.
[0032] like Figure 1 As shown, in the prior art, when the instrument panel cover 1 is installed on the instrument panel frame 2, the existing clip head 111' of the existing clip 11' abuts against the first limiting rib 21', and the existing support rib 112' abuts against the second limiting rib 22', so that after the instrument panel cover 1 is hit, the existing clip 11' cannot move and transmits all the impact force to the instrument panel frame 2. The energy of the impact can only be absorbed by the plastic deformation or fracture of the instrument panel frame 2. However, the impact absorption capacity of the instrument panel frame 2 is very limited, which makes the occupant's legs easily seriously injured, and greatly reduces the car's protection performance for the occupants.
[0033] Reference Figure 1 , and as Figures 2 to 5 As shown, in order to solve the problem that the existing instrument panel has limited energy absorption when it is hit, thereby causing injuries to the occupants, the instrument panel for a vehicle of the present invention includes an instrument panel cover 1 and an instrument panel frame 2. The instrument panel cover 1 is provided with a buckle 11. One side of the buckle 11 is provided with a second clamping head 112 and a first clamping head 111 from top to bottom. The height between the abutment point of the first clamping head 111 and the abutment point of the second clamping head 112 and the limiting rib 211 is Figure 5 The value of d1 in the figure is 12 mm, and a secondary step 114 and a primary step 113 are provided on the other side from top to bottom, that is, the height between the primary step 113 and the secondary step 114 is also 12 mm; a slot 21 is provided on the instrument panel frame 2, one side of the slot 21 is a limiting rib 211, and the other side is a collapse structure 212. The instrument panel is configured so that when the instrument panel cover 1 is normally installed on the instrument panel frame 2, the buckle 11 penetrates into the slot 21, the first clamp head 111 abuts against the limiting rib 211, and the collapse structure 212 abuts against the primary step 113; when the outer side of the instrument panel cover 1 is impacted, the collapse structure 212 collapses, and the abutment between the collapse structure 212 and the primary step 113 fails, and the buckle 11 moves downward until the collapse structure 212 abuts against the secondary step 114 again, and the second clamp head 112 abuts against the limiting rib 211 again.
[0034] The advantage of the above arrangement is that when the instrument panel of the present invention is normally installed, the instrument panel cover 1 is fixed on the instrument panel frame 2. Specifically, the buckle 11 of the instrument panel cover 1 penetrates into the card slot 21, and the first clamp head 111 is clamped on the limiting rib 211. At the same time, the collapse structure 212 on the instrument panel frame 2 abuts against the first step 113, so that the instrument panel cover 1 is fixed on the instrument panel frame 2, and the relative position of the instrument panel cover 1 and the instrument panel frame 2 is kept fixed. When the vehicle is hit, the occupant's legs will hit the instrument panel cover 1 under the action of inertia. After the instrument panel cover 1 is hit, the buckle 11 moves downward in the card slot 21, and the collapse structure 212 is stepped. 113 collapses after the downward force is applied. During the collapse process of the collapse structure 212, most of the impact force of the legs on the instrument panel cover 1 is absorbed to reduce the force of the instrument panel cover 1 on the legs, thereby reducing the damage of the instrument panel to the legs when the legs hit the instrument panel. After the collapse structure 212 fails at the first step 113, the buckle 11 continues to move downward. At this time, the collapse structure 212 rubs against the side of the buckle 11. During the friction process, the collapse structure 212 is worn by the buckle 11, further absorbing the impact energy. When the second step 114 of the buckle 11 abuts against the collapse structure 212, the second clamping head 112 of the buckle 11 is clamped on the limiting rib 211, and the buckle 11 stops moving.
[0035] Compared to the prior art, where the instrument panel cover 1 is rigidly connected to the instrument panel frame 2, when a leg strikes the instrument panel cover 1, the instrument panel frame 2 itself relies solely on plastic deformation or fracture to cushion the impact. In contrast, when the instrument panel of the present invention is impacted, the crush structure 212 collapses, cushioning the impact of the leg impact and correspondingly reducing the irreversible deformation of the entire instrument panel frame 2 caused by the impact. Post-impact repairs only require replacing the buckle 11 and the crush structure 212, significantly reducing repair costs. In the prior art, to reduce the risk of instrument panel collapse and deformation, the strength of the instrument panel frame 2 is often increased, resulting in minimal plastic deformation when a leg strikes the instrument panel. This significantly increases the risk of damage to the occupant's legs during an impact. However, weakening the instrument panel frame 2 can also easily cause the instrument panel to collapse and deform. The present invention utilizes the crush structure 212 to cushion the impact without restricting the strength of the instrument panel frame 2. This allows the strength of the instrument panel frame 2 to be increased as needed, preventing instrument panel collapse and deformation, improving the quality of the vehicle's interior, enhancing occupant protection, and enhancing vehicle safety.
[0036] like Figure 3 、 Figure 7 As shown, in a possible embodiment, the collapse structure 212 is a failure chamfer 2121. In order to make the collapse structure 212 effective when the impact force is greater than 2KN, the chamfer angle of the failure chamfer 2121 is set to 130°, as shown in FIG. Figure 3 The a shown in FIG is the chamfer angle of the failure chamfer 2121. Further, the width of the buckle 11 gradually increases from the first step 113 to the second step 114, forming an inclination angle, as shown in FIG. Figure 3 The d shown in FIG is the width of the buckle 11, and d2 is the width of the first step 113, which is also the width of the failed portion of the collapse structure 212 at the first step 113. The value of d2 is 0.7 mm. Figure 4 Where d3 is the width of the failed portion of the collapse structure 212 when it abuts against the secondary step 114. The value of d3 is 1.3 mm. The width of the secondary step 114 is greater than the width of the primary step 113. Figure 7 As shown, a weakening groove 115 is also provided on the buckle 11, and the weakening groove 115 is provided on the side of the first clamp head 111 and the second clamp head 112. The shape of the weakening groove 115 is a long strip from top to bottom. The length of the weakening groove 115 is d4, and the value of d4 is 29 mm. The width of the weakening groove 115 is d5, and the value of d5 is 1.2 mm.
[0037] The advantages of the above arrangement are: in order to ensure that the collapse structure 212 collapses when subjected to an impact force of 2KN, the collapse structure 212 is set to a failure chamfer 2121, and the angle of the failure chamfer 2121 is made 130 degrees as required. At this time, the collapse structure 212 is much smaller than the conventional bearing capacity. When the impact force is greater than 2KN, the collapse structure 212 breaks at the first step 113, thereby ensuring the limit failure. At the same time, in order to ensure that the collapse structure 212 can absorb energy when the buckle 11 moves downward, the width d of the buckle 11 gradually increases from the first step 113 to the second step 114, forming an inclination angle, and the collapse structure 212 breaks at the first step 113. 2 interferes with the first-level step 113 by 0.7 mm (d2). When the instrument panel cover 1 is impacted, the buckle 11 moves downward, and the second-level step 114 gradually moves to the position of the crush structure 212 and abuts against it. At this time, the total width of the failed, broken, and worn portions of the crush structure 212 is 1.3 mm (d3). During the movement of the buckle 11, the crush structure 212 rubs against the side of the buckle 11, causing the buckle 11 to wear the crush structure 212 and absorb a large amount of energy, effectively reducing the impact energy transmitted to the occupant's legs. Until the second-level step 114 of the buckle 11 abuts the crush structure 212, the buckle 11 stops moving downward.
[0038] When the instrument panel is hit by the occupant, the crush structure 212 collapses at the first step 113 and the limit at the first step 113 fails. As the buckle 11 moves downward, the crush structure 212 is worn by the buckle 11 through friction with the buckle 11, and then absorbs the impact energy. In order to ensure that the crush structure 212 collapses at the first step 113, the width of the first step 113 is generally set to be smaller, so that the contact area between the crush structure 212 and the first step 113 is smaller, so that the force per unit area of the first step 113 on the crush structure 212 is larger, which is conducive to the collapse of the crush structure 212. When the second step 114 on the buckle 11 moves to the crush structure 212, if the second step 11 If the width is set too small, the contact area between the crush structure 212 and the secondary step 114 is also small, resulting in a large force per unit area of the secondary step 114 on the crush structure 212. It is very likely that the crush structure 212 will not be able to successfully abut against the secondary step 114, but will continue to collapse at the secondary step 114, and the limit stop at the secondary step 114 will fail, causing the buckle 11 to continue to move downward, thereby causing damage to the instrument panel. Therefore, the width of the secondary step 114 is set to be larger than the width of the primary step 113, so that the force per unit area of the secondary step 114 on the crush structure 212 is small, allowing it to firmly abut against the secondary step 114, thereby preventing the limit stop at the secondary step 114 from failing and causing damage to the instrument panel.
[0039] In addition, in order to ensure that the buckle 11 can be deformed smoothly so that the second clamping head 112 abuts against the limiting rib 211, two 1.2mm*29mm weakening grooves 115 are made on the buckle 11. The weakening grooves 115 reduce the strength of the buckle 11, thereby enhancing the buckle 11 in the Figure 3 Plastic deformation in the left and right directions ensures that the first clamp 111 and the second clamp 112 can successfully abut against the limiting rib 211, and this can ensure that the collapse structure 212 is more effective, preventing the collapse structure 212 from being stuck with the buckle 11 and unable to smoothly abut against the secondary step 114, thereby affecting the energy absorption effect.
[0040] like Figure 3 As shown, in a possible embodiment, a rubber pad (not shown in the figure) is provided on the secondary step 114, and the collapse structure 212 is configured to abut against the rubber pad after being impacted, and an anti-slip protrusion (not shown in the figure) is provided on the side of the buckle 11 from the primary step 113 to the secondary step 114. Figure 6 As shown, in a possible embodiment, the crush structure 212 can also be a failure groove 2122, and there is no restriction on the crush structure 212. Those skilled in the art can set it according to their needs, as long as the crush structure 212 can collapse when the dashboard is hit.
[0041] The advantage of the above-mentioned arrangement is that a rubber pad is provided on the secondary step 114, so that when the crush structure 212 abuts against the secondary step 114, the rubber pad can provide a buffer for the crush structure 212. Specifically, when the impact force is large, the impact force is still large after the crush structure 212 collapses. The energy absorption of the hard collision between the crush structure 212 and the secondary step 114 is limited, and the elastic buffering of the rubber pad absorbs the remaining impact force, thereby further preventing the instrument panel from damaging the occupants. Furthermore, anti-slip protrusions are provided on the side of the buckle 11 from the first step 113 to the second step 114. When the collapse structure 212 fails at the first step 113, it will rub along the side of the buckle 11, and absorb the impact through the wear of the collapse structure 212. When the friction between the collapse structure 212 and the side of the buckle 11 is small, the collapse structure 212 and the buckle 11 slip during the downward movement of the buckle 11, thereby reducing the energy absorption. This embodiment increases the friction between the collapse structure 212 and the buckle 11 by providing anti-slip protrusions on the side of the buckle 11, thereby ensuring that during the movement of the buckle 11, the collapse structure 212 can absorb the impact energy through its own wear, thereby ensuring that the collapse is effective. In one embodiment, the collapse structure 212 may be a failure groove 2122 in addition to the collapse chamfer 2121. During an impact, the first step 113 applies a downward force to the failure groove 2122, thereby causing the collapse structure 212 to break at the failure groove 2122. The impact force during collapse can be adjusted by setting failure grooves 2122 of different depths.
[0042] In summary, the dashboard of the present invention is provided with a crush structure on the dashboard frame. When the occupant hits the dashboard cover, the crush deformation of the crush structure reduces the damage to the occupant's legs caused by the impact force, thereby enhancing the protection performance of the occupant in the car passenger compartment. Furthermore, by setting the crush structure as a crush chamfer and setting the chamfer angle of the crush chamfer according to the preset impact force, the crushing can be effective, thereby reducing the damage to the occupant. In the process of the buckle moving downward, the crush structure rubs against the side of the buckle and is damaged to absorb energy, thereby further absorbing the impact energy. By providing a weakening groove on the buckle, the plastic deformation of the buckle can be enhanced, so that the clamping head can successfully abut against the crush structure.
[0043] Finally, it should be noted that although the present invention is described by taking a car dashboard as an example, the car of the present invention can obviously be an electric car or a fuel car, etc.
[0044] It should be noted that the above-mentioned embodiments are only used to illustrate the principles of the present invention and are not intended to limit the scope of protection of the present invention. Without departing from the principles of the present invention, those skilled in the art can adjust the above-mentioned structure so that the present invention can be applied to more specific application scenarios.
[0045] For example, in an alternative embodiment, the chamfer angle of the failure chamfer 2121 is 130°, but this is not restrictive. The chamfer angle of the failure chamfer 2121 can also be 100° or 170°, or between 100° and 170°. Therefore, there is no restriction on the chamfer angle of the failure chamfer 2121. People in this field can set it according to their needs. These do not deviate from the principles of the present invention and therefore will fall within the scope of protection of the present invention.
[0046] For example, in an alternative embodiment, the number of weakening grooves 115 can be one, two, or five. Therefore, there is no limit on the number of weakening grooves 115. Those skilled in the art can set them as needed. These do not deviate from the principles of the present invention and therefore fall within the scope of protection of the present invention.
[0047] For example, in an alternative embodiment, the number of the snaps 11 and the slots 21 can be one or more, and there is no restriction on the number and setting position of the snaps 11 and the slots 21. People skilled in the art can set them according to their needs. These do not deviate from the principles of the present invention and therefore fall within the scope of protection of the present invention.
[0048] In addition, the present invention also provides a vehicle having the instrument panel for a vehicle as described in any one of the above embodiments.
[0049] Thus far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art may make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will fall within the scope of protection of the present invention.
