Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, and in particular to a door panel connector and a vehicle. Background Technology

[0002] With the continuous development of vehicle-related technologies, airbags have always been an important safety measure. They are mostly used in vehicle steering wheels and doors to protect the safety of passengers when a vehicle is involved in a collision.

[0003] In side-impact collisions, occupant injuries are often caused by secondary impacts between the occupant and interior components. Seat airbags are crucial for preventing secondary collisions, and the deployment of side-impact airbags requires a certain amount of lateral space. Currently, the connection between the inner door panel (a stamped steel part) and the door trim assembly (a molded PP composite material part) is as follows: the lower part of the water-cut stop of the door trim assembly is secured to mounting holes on the inner door panel by several plastic clips. For ease of installation and removal, the clamping force cannot be too large, thus limiting the pull-out force this connection method can withstand. These clips are easily pulled out during side-impact collisions due to excessive load on the door trim assembly; furthermore, due to the inherent limitations of the material, excessive interference fit can cause the clips to break even if they are not pulled out. Subsequently, the door trim assembly detaches, encroaching on the deployment space of the side-impact airbag. The airbag cannot fill the space between the occupant's upper torso and the door trim panel, greatly increasing the risk of secondary impacts between the occupant and interior components.

[0004] The existing utility model patent with authorization announcement number CN202788520U discloses a car door assembly and a car, wherein the car door assembly includes a car door inner panel sheet metal part and a car door guard plate, and the front of the car door inner panel sheet metal part and the side of the car door guard plate are fixed together by a lateral fixing bracket.

[0005] As in the above technical solution, the fixing bracket is fixed with bolts. Although this can improve the connection strength between the inner door panel and the door guard panel, making it less likely for the inner door panel to fall off, it also means that when the vehicle suffers a side collision, it will transmit a greater impact force to the driver and passengers. The collision when the driver and passengers come into contact with the airbag can easily cause personal injury. Therefore, setting a certain buffer structure in the force transmission path is one of the effective measures to reduce personal injury. Utility Model Content

[0006] In view of this, this utility model proposes a door panel connector and vehicle that can achieve collision buffering, thereby solving the problem that the existing door inner panel and door panel have excessive connection strength, which can easily transmit large impact forces and cause personal injury.

[0007] The technical solution of this utility model is implemented as follows:

[0008] On the one hand, this utility model provides a door panel connector, including a bracket, a first connecting end, and a second connecting end, wherein,

[0009] The first connecting end and the second connecting end are arranged opposite each other on both sides of the bracket;

[0010] The first connecting end is used to connect to the door panel, and the second connecting end is used to connect to the inner door panel.

[0011] An inducing deformation part is provided between the first or second connecting end and the bracket.

[0012] Based on the above technical solutions, preferably, the support includes a crossbeam and an end plate, wherein,

[0013] A first groove is provided on the crossbeam;

[0014] End plates are installed at both ends of the crossbeam. The end plates are flat and have bolt holes.

[0015] Based on the above technical solutions, preferably, the second connecting end protrudes from the bracket, and bolt holes are provided on the second connecting end.

[0016] Based on the above technical solutions, preferably, the first connecting end protrudes from the bracket, and bolt holes are provided on the first connecting end.

[0017] Based on the above technical solutions, preferably, the first connecting end includes a straight plate and an inclined plate, wherein,

[0018] The straight plate is connected to the edge of the bracket via a slanted plate;

[0019] The edges of the straight plate and the stand are parallel;

[0020] The inclined plate is set at an angle relative to the straight plate, and the inclined plate is the part that induces deformation.

[0021] Based on the above technical solutions, preferably, a second groove is provided on the inclined plate.

[0022] Based on the above technical solutions, preferably, the second groove is connected to the first groove, or the second groove is spaced apart from the first groove.

[0023] Based on the above technical solutions, preferably, when the second groove is spaced apart from the first groove, the second groove extends onto the bracket.

[0024] Based on the above technical solutions, preferably, at least two first connecting ends are provided, one of which corresponds to the crossbeam and the other corresponds to an end plate.

[0025] On the other hand, the utility model provides a vehicle including the aforementioned door panel connector.

[0026] The door panel connector and vehicle of this utility model have the following advantages over the prior art:

[0027] (1) By setting an inducing deformation part on the first connecting end of the bracket for connecting the door panel or the second connecting end for connecting the inner panel of the door, when the vehicle is hit, the inducing deformation part will deform as the airbag comes into contact with the human body, thereby reducing the impact force of the collision on the human body, reducing collision damage, and helping to protect the safety of the driver and passengers.

[0028] (2) The bracket is divided into two parts: a crossbeam and an end plate. The crossbeam has a first groove, which helps to improve the structural strength of the bracket. The end plate is set as a flat structure, which facilitates connection with the inner panel of the car door, so as to further ensure the stability of the installation.

[0029] (3) The deformation-inducing part is composed of an inclined plate. When the door is hit and the airbag comes into contact with the human body, the inclined plate will cause deformation between the door panel and the bracket, thereby playing a buffering role and reducing personal injury. At the same time, a second groove is provided on the inclined plate, which can reasonably strengthen the structural strength of the deformation-inducing part, so as to avoid deformation of the door panel connector during transportation and installation, thereby ensuring the reliability of the application.

[0036] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0037] like Figures 1-4 As shown, the door panel connector of this utility model includes a bracket 1, a first connecting end 2, and a second connecting end 3.

[0038] like Figures 1-4 As shown, the first connecting end 2 and the second connecting end 3 are disposed opposite to each other on both sides of the bracket 1; the first connecting end 2 is used to connect the door panel, and the second connecting end 3 is used to connect the inner door panel; an inducing deformation part is provided between the first connecting end 2 or the second connecting end 3 and the bracket 1.

[0039] As described above, when this door panel connector is used, the first connecting end 2 is connected to the door panel, and the second connecting end 3 is connected to the inner door panel.

[0040] When in use, if a side impact occurs, the inner door panel will not detach from the door panel due to the connecting action of the door panel connector. This avoids the space occupied by the detached inner door panel, leaving space for the airbag to deploy and solving the problem of interference between the inner door panel and the airbag.

[0041] After the airbag deploys, if a person collides with the airbag, the airbag will rebound and impact the inner door panel. At this time, the door panel connector will be subjected to force, that is, a force opposite to the impact force. When the door panel connector is subjected to bidirectional force, the inducing deformation part on the first connecting end 2 or the second connecting end 3 will deform, thereby playing a good buffering role and reducing the risk of personal injury.

[0042] like Figure 1 and Figure 2 As shown, the bracket 1 includes a crossbeam 11 and an end plate 12. The crossbeam 11 has a first groove 101. The end plate 12 is provided at both ends of the crossbeam 11. The end plate 12 has a flat plate structure and bolt holes.

[0043] As described above, the bracket 1 consists of a crossbeam 11 and an end plate 12. The crossbeam 11 is used to set the first connecting end 2 and the second connecting end 3, and the end plate 12 is used to connect the inner panel of the car door. It is set as a flat plate structure, which can improve the connection strength and connection convenience.

[0044] The crossbeam 11 has a first groove 101, which can improve the structural strength of the crossbeam 11.

[0045] like Figure 1 As shown, the second connecting end 3 protrudes from the bracket 1, and bolt holes are provided on the second connecting end 3;

[0046] As described above, during installation, the second connecting end 3 is designed as a protruding structure and has bolt holes, so as to facilitate the connection of the second connecting end 3 to the inner panel of the car door by bolts.

[0047] Specifically, the crossbeam 11 is provided with an arc-shaped segment, and the second connecting end 3 is connected to the arc-shaped segment. This increases the connection area between the second connecting end 3 and the crossbeam 11, thus ensuring the strength of the connection structure.

[0048] like Figure 1 As shown, the first connecting end 2 protrudes from the bracket 1, and bolt holes are provided on the first connecting end 2;

[0049] As described above, during installation, the first connecting end 2 is designed as a protruding structure with bolt holes, so as to facilitate the connection of the first connecting end 2 to the door panel by bolts.

[0050] like Figure 1 and Figure 3 As shown, the first connecting end 2 includes a straight plate 21 and an inclined plate 22, wherein the straight plate 21 is connected to the edge of the support 1 through the inclined plate 22; the straight plate 21 is parallel to the edge of the support 1; the inclined plate 22 is inclined relative to the straight plate 21, and the inclined plate 22 is a deformation-inducing part;

[0051] As described above, in the first connecting end 2, the straight plate 21 is used to connect the door panel, and the inclined plate 22 is used to connect the straight plate 21 and the bracket 1. Since the inclined plate 22 is inclined relative to the edge of the first connecting end 2 and the bracket 1, it will undergo displacement deformation when subjected to force, thereby achieving buffering and reducing the impact force.

[0052] In some embodiments, the inclined plate 22 is disposed between the second connecting end 3 and the bracket 1, and the end plate 12 of the bracket 1 is configured as a protruding structure, and the inclined plate 22 is disposed thereon.

[0053] like Figure 1As shown, a second groove 201 is provided on the inclined plate 22, which can effectively increase the structural strength of the inclined plate 22, thereby avoiding deformation problems of the door panel connector during transportation and assembly, and thus ensuring the reliability of the application.

[0054] like Figure 1 As shown, the second groove 201 is connected to the first groove 101, or the second groove 201 is spaced apart from the first groove 101;

[0055] As described above, when laying out the structure, the second groove 201 can be formed separately or connected with the first groove 101 to be integrally stamped, thereby achieving targeted structural reinforcement or overall structural reinforcement.

[0056] In some embodiments, when the second groove 201 is spaced apart from the first groove 101, the second groove 201 extends onto the bracket 1;

[0057] As described above, when the second groove 201 and the first groove 101 are both formed separately, the second groove 201 can extend to the bracket 1, thereby ensuring the strength of the connection structure between the bracket 1 and the first connecting end 2.

[0058] In some embodiments, the first groove 101 extends to the first connection end 2.

[0059] Specifically, at least two first connecting ends 2 are provided, one of which corresponds to the crossbeam 11 and the other corresponds to an end plate 12;

[0060] As described above, by setting multiple first connection ends 2, force can be effectively distributed;

[0061] Specifically, the first connecting end 2 corresponding to the end plate 12 can relieve force and buffer more quickly, while the first connecting end 2 corresponding to the crossbeam 11 can ensure that the crossbeam 11 can transmit force evenly, so that the crossbeam 11 also participates in the buffering work, thereby further improving the reliability of the application.

[0062] Specifically, the beam 11 has an arc-shaped structure when viewed from above, thus leaving room for deformation, and an L-shaped interface when viewed from the side, thereby ensuring a certain structural strength.

[0063] The vehicle of this utility model includes the aforementioned door panel connector.

[0064] Specific implementation steps:

[0065] The bracket 1 is connected to the door panel via the first connecting end 2, and the bracket 1 is connected to the inner door panel via the second connecting end 3. After the door panel is impacted, the airbag deploys on the side of the inner door panel that is relatively far away from the door panel. Then the airbag contacts the human body, the inner door panel is stressed, and then the door panel connector is stressed, causing the inclined plate 22 to be stressed, and the straight plate 21 and the bracket 1 to deform and buffer.

[0066] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
