Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of automobile structures, in particular to an automobile door panel anti-collision structure. Background Art
[0002] In the impact collision test of automobiles, it is necessary to set an anti-collision structure in the door, and use the anti-collision structure to bear the impact force of the passenger's legs, so as to protect the passenger's legs. At present, the anti-collision structure is mainly a plate-like structure, and a blind groove extending into the block structure is set on one side of the plate-like structure, and then a convex edge protruding out of the plate-like structure is set on the outer side of the plate-like structure, and a mounting hole is set on the convex edge, and the entire anti-collision structure is fixed in the car door panel by using the mounting hole.
[0003] Although the anti-collision structure in the prior art can be installed smoothly and play a certain role in safety protection, there are some problems with the existing anti-collision structure during actual tests and subsequent use: 1. Since a blind groove structure is set on one side of the plate-like structure, when the plate-like structure is subjected to impact force, the plate-like structure is easily damaged and cannot play a good protective role. If the anti-collision structure is set to a solid shape, it will not only seriously increase the weight of the anti-collision structure, but also cause a significant increase in the cost of the anti-collision structure; 2. Since the existing anti-collision structure is fixed by using the mounting holes opened on the outer convex edge of the plate-like structure, only the edge part of the anti-collision structure is fixed, so that the anti-collision structure is easy to loosen and fail when the anti-collision structure is subjected to impact force, and the stability after installation is poor. Utility Model Content
[0004] The utility model aims to provide an automobile door panel anti-collision structure to solve the problems of poor anti-collision performance and poor stability of the automobile door panel anti-collision structure in the prior art.
[0005] To solve the above problems, the utility model adopts the following technical solutions: an automobile door panel anti-collision structure, including an anti-collision block body, on which a plurality of deformation shrinkage grooves are arranged, the plurality of deformation shrinkage grooves are arranged along the length direction of the anti-collision block body, a recessed portion is arranged between adjacent deformation shrinkage grooves, a fixing portion is arranged in the recessed portion; a plurality of structural reinforcements are arranged in the deformation shrinkage grooves, and the plurality of structural reinforcements are arranged alternately.
[0006] The principle and beneficial effects of the present scheme are as follows: in the present application, a plurality of deformation shrinkage grooves are arranged on the anti-collision block body, and the deformation shrinkage grooves are utilized to provide deformation space for the anti-collision block body to deform when it is subjected to impact force, so that the anti-collision block body has good anti-collision performance; at the same time, in the present application, a plurality of structural reinforcements are arranged in the deformation shrinkage grooves, and the plurality of structural reinforcements are arranged in a staggered manner. By arranging staggered structural reinforcements in the deformation shrinkage grooves, the strength of the entire anti-collision structure is effectively improved without significantly increasing the weight of the anti-collision structure, so that the anti-collision structure can withstand greater impact force and play a better safety protection role.
[0007] In the present application, there are multiple deformation shrinkage grooves and the multiple deformation shrinkage grooves are arranged along the length direction of the anti-collision block body, so that the anti-collision block body has deformation shrinkage grooves at different positions in the length direction, effectively ensuring the impact resistance of all positions of the anti-collision structure; in addition, in the present application, a recessed portion is provided between adjacent deformation shrinkage grooves, and a fixing portion is provided in the recessed portion, so that multiple fixing portions can be provided on the anti-collision block body, and the multiple fixing portions are provided along the length direction of the anti-collision block body, which can more stably fix the anti-collision block body, so that the anti-collision structure will not easily loosen under the action of impact force; at the same time, the fixing portion in the present application is provided in the recessed portion, and the recessed portion is used to accommodate the fixing portion, so that when the anti-collision structure is deformed by impact, the fixing portion can be left in the recessed portion to avoid the fixing portion protruding out of the anti-collision block body and causing secondary injury to the passenger.
[0008] Preferably, as an improvement, the fixing portion includes a fixing hole and a fusion welding column fixedly connected to the anti-collision block body, and the number of the fusion welding columns is multiple and the multiple fusion welding columns are evenly arranged along the circumference of the fixing hole.
[0009] In this solution, the fixing part includes a fixing hole and a welding column. When the anti-collision structure needs to be fixed in the automobile door panel, it is only necessary to insert the BOSS column in the automobile door panel in the prior art into the fixing hole, and then melt the BOSS column and the welding column to stably complete the connection between the anti-collision block body and the automobile door panel.
[0010] Preferably, as an improvement, the recessed portion comprises a recessed blind groove integrally formed on the anti-collision block body, and the fusion welding column is arranged in the recessed blind groove.
[0011] In this solution, a recessed blind groove is integrally formed on one side of the anti-collision block body, and a fusion welding column is arranged in the recessed blind groove. To fix the anti-collision block body on the car door panel, it is only necessary to fit the side of the anti-collision block body away from the side where the recessed blind groove is set to the car door panel, and then melt and fix it. This state can form a surface fit between the anti-collision block body and the car door panel, so that the anti-collision block body can be fixed more firmly.
[0012] Preferably, as an improvement, a boss is provided on one side of the anti-collision block body facing away from the concave blind groove and extends outside the anti-collision block body. The fixing hole penetrates through the boss, and a thickness-reducing groove extending into the concave blind groove and matching the boss is provided in the concave blind groove. The depth value of the thickness-reducing groove is equal to the height value of the boss protruding outside the anti-collision block body.
[0013] In this solution, a boss structure is provided on the outer side of the anti-collision block body where the fixing hole is located (that is, the side of the anti-collision block body facing away from the concave blind groove). When fixing the anti-collision block body, the boss structure forms a fit with the car door panel. At this time, when a fixing structure such as a BOSS column passes through the fixing hole and is melt-fixed to the anti-collision block body, during the fixing process of the BOSS column and the like, the anti-collision block body can be more stably and firmly fixed to the car door panel, avoiding the problem of warping after fixing caused by the slight deformation of the anti-collision block body due to the fit between the large plane on the anti-collision block body and the car door panel; in addition, in this solution, a thickness-reducing groove with a depth equal to the height value of the boss is provided in the concave blind groove to ensure that the anti-collision block body can maintain the same thickness at different positions after the boss structure is provided, so as to achieve uniform and high-quality molding during the injection molding process of the anti-collision block body.
[0014] Preferably, as an improvement, the height value of the boss protruding outside the anti-collision block body is 1.2 - 2.0 mm.
[0015] In this solution, setting the height value of the boss to 1.2 - 2.0 mm can achieve a good support effect and avoid the excessive height value of the boss.
[0016] Preferably, as an improvement, the structural reinforcement includes a reinforcing rib plate integrally formed on the anti-collision block body, and the end of the reinforcing rib plate away from the anti-collision block body is flush with the top of the concave portion.
[0017] In this solution, the reinforcing rib plate is integrally formed on the anti-collision block body, which is convenient for molding. And the end of the reinforcing rib plate away from the anti-collision block body is flush with the top of the concave portion, making the overall appearance of the anti-collision structure in a plate-like structure, which can better achieve the anti-impact effect.
[0018] Preferably, as an improvement, multiple reinforcing rib plates in the same deformation and shrinkage groove are arranged perpendicular to each other or intersect at an angle to form an array diamond structure.
[0019] In this solution, multiple reinforcing rib plates are arranged in an array diamond shape perpendicular to each other or at an angle to each other, so that all the reinforcing rib plates are connected to form a grid-like structure, which has better anti-impact performance.
[0020] Preferably, as an improvement, the middle width of the anti-collision block body is greater than the widths of both ends, and fixing parts are also arranged on the anti-collision block body outside the deformation and contraction groove in the middle of the anti-collision block body.
[0021] In this solution, the anti-collision block body is set to have a structure that is large in the middle and small at both ends, making the structure of the anti-collision block body more stable. Moreover, fixing parts are also arranged outside the deformation and contraction groove in the middle of the anti-collision block body, and these fixing parts are used to strengthen and fix the middle position of the anti-collision block body, so that the anti-collision block body can be fixed more firmly.
[0022] Preferably, as an improvement, a recessed groove that is recessed into the anti-collision block body is arranged on the outside of the anti-collision block body.
[0023] In this solution, a recessed groove that is recessed into the anti-collision block body is arranged on the outer wall of the anti-collision block body, avoiding the situation where the outer wall of the anti-collision block body is flat and has low strength. After setting the recessed groove, the strength of the anti-collision block body can be further improved, so that the anti-collision block body can achieve a better anti-impact effect.
[0024] Preferably, as an improvement, a reinforcing skirt is fixedly connected circumferentially on the outside of the anti-collision block body.
[0025] In this solution, by circumferentially arranging a reinforcing skirt on the outside of the anti-collision block body, the reinforcing skirt plays a role in strengthening the structure of the outside of the anti-collision block body, thereby further improving the structural strength of the anti-collision block body, so that the anti-collision block body can achieve a better anti-impact effect.

[0031] Embodiment 1
[0032] This embodiment is as shown in the attached Figure 1As shown: An anti-collision structure for a car door panel, including an anti-collision block body 1. The anti-collision block body 1 is in a shape that is larger in the middle and smaller at both ends along the length direction. A plurality of deformation and shrinkage grooves 2 are provided on the anti-collision block body 1, and the plurality of deformation and shrinkage grooves 2 are arranged along the length direction of the anti-collision block body 1. Specifically, a plurality of vertically arranged vertical walls are integrally formed on the anti-collision block body 1, and the plurality of vertical walls enclose the aforementioned deformation and shrinkage grooves 2; of course, in order to facilitate and stably injection mold the vertical walls, a draft angle can be set on the vertical walls, which will not be elaborated here.
[0033] As Figure 1 shown, a recessed portion is provided between adjacent deformation and shrinkage grooves 2, and a fixing portion is provided in the recessed portion. Specifically, the recessed portion is a recessed blind groove 3 integrally formed on the anti-collision block body 1, and the top of the recessed blind groove 3 is open; the fixing portion includes a fixing hole 4 and a welding post 5 integrally formed on the anti-collision block body 1. The welding post 5 is arranged on the inner bottom wall of the recessed blind groove 3. The number of welding posts 5 is multiple and the multiple welding posts 5 are evenly arranged along the circumferential direction of the fixing hole 4, Figure 1 and the number of welding posts 5 in this example is six. In this embodiment, the number of deformation and shrinkage grooves 2 is three, and the number of fixing portions arranged along the length direction of the anti-collision block body 1 is two; in addition, a fixing portion is also provided on the anti-collision block body 1 on the front side outside the deformation and shrinkage groove 2 in the middle of the anti-collision block body 1, which will not be elaborated here.
[0034] As Figure 1 shown, a number of structural strengthening members are provided in the deformation and shrinkage grooves 2, and the number of structural strengthening members are arranged in a staggered manner. Specifically, the structural strengthening members include reinforcing rib plates 6 integrally formed on the anti-collision block body 1. The top of the reinforcing rib plates 6 is flush with the top of the recessed blind groove 3, and in this embodiment, the reinforcing rib plates 6 are perpendicular to each other.
[0035] Combined with Figure 1 、 Figure 2 and Figure 3 , in this embodiment, in order to improve the installation stability of the anti-collision block body 1, a boss 7 extending downward from the bottom side of the anti-collision block body 1 is provided on the bottom side of the anti-collision block body 1. The fixing hole 4 passes through the boss 7. The cross-sectional area of the boss 7 is smaller than the cross-sectional area of the blind hole groove, that is, only the boss 7 structure is provided around the fixing hole 4, and the dimension of the boss 7 protruding downward from the bottom surface of the anti-collision block body 1 is 1.2 - 2.0 mm, preferably 1.5 mm; at the same time, in order to enable the anti-collision block body 1 to be better injection molded, a thickness-reducing groove 8 is integrally formed on the bottom wall of the recessed blind groove 3 and extends downward. The shape and size of the thickness-reducing groove 8 are adapted to the shape and size of the boss 7, and the depth of the thickness-reducing groove 8 is equal to the dimension of the boss 7 protruding outside the anti-collision block body 1.
[0036] As Figure 1As shown in the figure, in this embodiment, in order to further improve the structural strength of the anti-collision block body 1, a reinforcing skirt 9 protruding beyond the side wall of the anti-collision block body 1 is integrally formed at a position near the bottom of the outer wall of the anti-collision block body 1, and a concave groove 10 recessed into the anti-collision block body 1 is integrally formed on the rear side wall of the anti-collision block body 1. The anti-deformation performance of the anti-collision block body 1 is further improved by using the reinforcing skirt 9 and the concave groove 10, so that the anti-collision block body 1 can play a better buffering and protecting role.
[0037] The specific implementation process is as follows:
[0038] In this embodiment, when installing and fixing the anti-collision structure to the car door panel in the prior art, the bottom side of the boss 7 is attached to the car door panel, and the BOSS column provided on the car door panel in the prior art is inserted into the fixing hole 4, and then the BOSS column and the welding column 5 are melted and welded and fixed by a melting device, so that the entire anti-collision structure is stably fixed. Since the deformation shrinkage groove 2 is provided in the anti-collision block body 1, when the anti-collision structure is deformed by an external impact force, the deformation shrinkage groove 2 can provide space for the deformation, so that the anti-collision structure has good anti-impact performance. At the same time, in this embodiment, reinforcing rib plates 6, reinforcing skirts 9 and concave grooves 10 and other reinforcing structures are provided on the anti-collision block body 1, so that the anti-collision structure is light in overall weight and has good strength, and can better withstand external impact forces.
[0039] Embodiment Two
[0040] The difference between Embodiment Two and Embodiment One is that in Embodiment One, multiple reinforcing rib plates 6 in the same deformation shrinkage groove 2 are arranged perpendicular to and staggered with each other. In this embodiment, in order to further improve the structural strength of the anti-collision structure, multiple reinforcing rib plates 6 are arranged in a staggered form with an included angle between them, and the included angle is preferably 45°, so that all the reinforcing rib plates 6 enclose an array rhombus shape. Of course, in other embodiments other than this embodiment, the shape enclosed by the reinforcing rib plates 6 can also be set as a regular pentagon or a regular hexagon, which will not be elaborated here.
