Description

Technical Field

[0001] The utility model belongs to the technical field of vehicle body parts, and in particular relates to a C-pillar inner plate reinforcement plate for an automobile. Background Art

[0002] With the rapid development of the automobile industry and the increasing requirements for automobile safety performance, the structural design of automobiles, especially the reinforcement design of key parts such as the C-pillar, has become a research focus in the automobile manufacturing field. As an important structural component connecting the roof and the rear body, the strength and stability of the C-pillar are directly related to the overall safety performance of the vehicle. Therefore, an inner panel reinforcement plate will be fixed inside the C-pillar to improve the sturdiness of the C-pillar.

[0003] However, existing automobile C-pillar inner panel reinforcement plates usually only provide hard support but do not have a buffering effect. When the vehicle is hit, they will directly use hard blocking to deal with the impact force, which may cause the impact force to be directly transmitted to other parts of the vehicle body, increasing the risk of structural damage; secondly, existing inner panel reinforcement plates are often directly fixed inside the automobile C-pillar without forming an effective connection with other parts of the vehicle body (such as the roof or the rear body). This design may still maintain the integrity of the structure when dealing with small-area impacts, but when the impact area is too large or the impact force is too strong, the automobile C-pillar may be directly knocked off due to lack of sufficient support, seriously threatening the safety of passengers. Utility Model Content

[0004] The utility model aims to provide a C-pillar inner plate reinforcement plate for an automobile, so as to solve the problems mentioned in the background technology.

[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0006] The utility model discloses a C-pillar inner plate reinforcement plate for an automobile, comprising the C-pillar for an automobile, a reinforcement member, a fixing frame and an extension plate, wherein the upper end of the C-pillar for an automobile is fixed to the roof of the automobile by bolts, and the lower end of the C-pillar for an automobile is fixed to the rear body of the automobile by bolts; a reinforcement member is fixed to one side of the C-pillar for an automobile, wherein a plurality of fixing frames are fixed to the other side of the reinforcement member by welding, and the extension plate is fixed to the interior of the fixing frame by bolts; the upper end of the extension plate is fixed to the roof of the automobile by bolts, and the lower end of the extension plate is fixed to the rear body of the automobile by bolts; the reinforcement member comprises an outer shell, a corrugated plate, a first buffer frame and a second buffer frame, the outer shell is fixed to the C-pillar for an automobile by bolts, and the inner part of the outer shell is fixed to the corrugated plate by welding; a first buffer frame is movably arranged between the corrugated plate and the C-pillar for an automobile, and a second buffer frame is movably arranged between the corrugated plate and the outer shell.

[0007] Further, a sound-absorbing cotton is fixed to the inner wall of the housing by screws. Such a setting can absorb the noise generated during the driving of the vehicle.

[0008] Further, both the first buffer frame and the second buffer frame adopt a honeycomb structure, and rubber sleeves are wrapped around the outer sides of the first buffer frame and the second buffer frame. Such a setting can effectively absorb and disperse the impact force from the outside and reduce the damage to the C-pillar of the vehicle and its surrounding structures.

[0009] Further, the fixing frame adopts a "C"-shaped structure. Such a setting fixes the reinforcing members to the roof of the vehicle and the rear body of the vehicle respectively.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] First, when the vehicle is subjected to a relatively small impact force, the first buffer frame and the second buffer frame will quickly come into play. Their honeycomb structure, combined with the wrapping of the rubber sleeves, can absorb and disperse the impact force. When the impact force is too large, the first buffer frame and the second buffer frame will still absorb part of the impact force, and then a more solid overall structure is jointly constructed by the housing, the fixing frame and the extension plate. This structure can tightly connect the C-pillar of the vehicle to the body, forming a strong support system between the C-pillar of the vehicle and the body to rigidly block the impact force and prevent the body structure from being severely deformed or damaged.

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] In the description of the present invention, it should be understood that the terms "upper", "middle", "outer", "inner", "all around" and the like indicating directions or positional relationships are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limitations on the present invention.

[0019] See also Figure 1 and Figure 2 As shown, the utility model is a C-pillar inner plate reinforcement plate for an automobile, comprising an automobile C-pillar 1, a reinforcement member 2, a fixing frame 3 and an expansion plate 4, wherein the upper end of the automobile C-pillar 1 is fixed to the automobile roof by bolts, and the lower end of the automobile C-pillar 1 is fixed to the rear body of the automobile by bolts; a reinforcement member 2 is fixed to one side of the automobile C-pillar 1, wherein a plurality of fixing frames 3 are fixed to the other side of the reinforcement member 2 by welding, and an expansion plate 4 is fixed to the interior of the fixing frame 3 by bolts; the upper end of the expansion plate 4 is fixed to the automobile roof by bolts, and the lower end of the expansion plate 4 is fixed to the rear body of the automobile by bolts; the reinforcement member 2 comprises an outer shell 21, a corrugated plate 22, a first buffer frame 23 and a second buffer frame 24, the outer shell 21 is fixed to the automobile C-pillar 1 by bolts, and the inner part of the outer shell 21 is fixed to the corrugated plate 22 by welding; a first buffer frame 23 is movably arranged between the corrugated plate 22 and the automobile C-pillar 1, and a second buffer frame 24 is movably arranged between the corrugated plate 22 and the outer shell 21.

[0020] Specifically, the inner wall of the outer shell 21 is fixed with sound-absorbing cotton by screws, which can absorb the noise generated when the first buffer frame 23 and the second buffer frame 24 shake during the driving of the car.

[0021] Specifically, the first buffer frame 23 and the second buffer frame 24 both adopt a honeycomb structure, and the outer sides of the first buffer frame 23 and the second buffer frame 24 are wrapped with rubber sleeves. When in use, the first buffer frame 23 and the second buffer frame 24 can effectively absorb and disperse the impact force from the outside, reducing damage to the automobile C-pillar 1 and its surrounding structures. At the same time, the provision of the rubber sleeve can prevent the first buffer frame 23 and the second buffer frame 24 from scratching the automobile C-pillar 1.

[0022] Specifically, the fixing frame 3 adopts a "C"-shaped structure. Such a setting facilitates the fixing of the extension plate 4 inside the fixing frame 3, thereby fixing the reinforcing member 2 to the car roof and the rear body of the car respectively, ensuring the close combination of the reinforcing member 2 and the body.

[0023] Please refer to Figure 1-2 As shown, the present utility model is an inner panel reinforcing plate for a car C-pillar. Its working principle is as follows: When the vehicle is subjected to a relatively small impact force, the first buffer frame 23 and the second buffer frame 24, as the main buffer elements, can quickly respond and absorb the impact force. The honeycomb structure they adopt allows for controllable deformation when subjected to external forces, thereby effectively dispersing and absorbing the impact energy. In this way, the impact force on the surrounding structure of the car C-pillar 1 can be reduced at the initial stage of the impact, protecting the overall structural integrity of the vehicle. However, when the vehicle is subjected to a relatively large impact force, the first buffer frame 23 and the second buffer frame 24 will still play a role first and buffer the impact force initially. They can absorb part of the impact energy. If the impact force exceeds the bearing capacity of the first buffer frame 23 and the second buffer frame 24, at this time, the outer shell 21, the fixing frame 3, and the extension plate 4 will work together to form a strong support structure to rigidly block the remaining impact force.
