[0002] In the structure of vehicle doors, door reinforcement plates are needed to improve the strength and rigidity of the door. As a key component affecting door performance, the door reinforcement plate plays a crucial role.

[0003] The existing door reinforcement plates are too thick and heavy, which is not conducive to the requirement of lightweight doors.

[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0005] This disclosure provides a door reinforcement assembly, a door, and a vehicle, which is beneficial for door weight reduction.

[0006] According to a first aspect of this disclosure, a door reinforcement assembly is provided, comprising:

[0007] The base plate is used to connect to the inner panel of the car door.

[0008] A reinforcing plate is stacked on the substrate and connected to the substrate, with a portion of the reinforcing plate forming a cavity with the substrate.

[0009] In one embodiment of this disclosure, the cavity extends along a circular trajectory.

[0010] In one embodiment of this disclosure, the reinforcing plate has a mounting hole for mounting a limiter, and the cavity extends along a circular trajectory centered on the mounting hole.

[0011] In one embodiment of this disclosure, the door reinforcement assembly further includes a mounting plate stacked on the base plate and connected to the base plate, the mounting plate and the reinforcement plate being located on the same side of the base plate, and the mounting plate being used to mount a hinge.

[0012] In one embodiment of this disclosure, the substrate has a mounting groove, and the mounting plate is fixed in the mounting groove.

[0013] In one embodiment of this disclosure, the mounting plate includes a mounting portion and a positioning portion disposed on a surface away from the substrate. The positioning portion has a threaded hole extending toward the mounting portion, and the threaded hole is used for connection with the hinge via a threaded element.

[0014] In one embodiment of this disclosure, the mounting portion has a first welding hole, and the substrate is welded to the mounting portion through the first welding hole;

[0015] The reinforcing plate has a second welding hole, and the substrate is welded to the reinforcing plate through the second welding hole.

[0016] In one embodiment of this disclosure, the substrate is provided with at least one reinforcing rib and / or at least one weight-reducing hole.

[0031] This disclosure provides a vehicle, which can be an automobile, train, bullet train, high-speed train, or other type of vehicle. The vehicle may include a vehicle body and a vehicle frame. The vehicle body may include a chassis, frame, wheels, braking system, steering system, electrical system, etc. The vehicle frame may include a body shell, doors, windows, and body trim.

[0032] A vehicle door may include an inner door panel, an outer door panel, a door window frame, a door reinforcement assembly, hinges, limiters, and a door locking mechanism. The inner and outer door panels are positioned opposite each other to form the door body. The door window frame connects to either the inner or outer door panel for mounting the window glass. The door reinforcement assembly is located on the inner door panel, and the hinges and limiters are located on the side of the door reinforcement assembly furthest from the inner door panel to allow the door to rotate. The door locking mechanism is located on both the inner and outer door panels and is used to lock or unlock the door.

[0033] See Figure 1 and Figure 2The door reinforcement assembly may include a base plate 1 and a reinforcing plate 2. The base plate 1 is used to connect with the inner panel of the door. The reinforcing plate 2 is stacked on the base plate 1 and connected to the base plate 1. A cavity 3 is formed between a portion of the reinforcing plate 2 and the base plate 1. The reinforcing plate 2 is used to install a limiter.

[0034] In the embodiments of this disclosure, on the one hand, the door reinforcement assembly is divided into a base plate 1 and a reinforcing plate 2. The reinforcing plate 2 is provided in the area where the limiter is installed on the base plate 1 to achieve local reinforcement. In areas where reinforcement is not required, the thickness of the base plate 1 can be reduced, thereby reducing the weight of the base plate 1 and contributing to the lightweighting of the door. On the other hand, the reinforcing plate 2 and the base plate 1 can form a cavity 3, which has higher strength and lighter weight than the ribs formed by stamping the base plate 1, and reduces the manufacturing difficulty.

[0035] In one embodiment of this disclosure, the cavity 3 can be a closed cavity 3 or an open cavity 3, depending on the specific requirements, and is not limited here.

[0036] In one embodiment of this disclosure, see Figure 2 The cavity 3 extends along a circular trajectory. This further enhances the strength of the base plate 1 in the area where the limiter is installed, thereby improving the reliability of the door reinforcement assembly. Furthermore, it also reduces the weight of the door reinforcement assembly.

[0037] In one embodiment of this disclosure, see Figures 1-3 The reinforcing plate 2 has a mounting hole 21 for mounting a limiter, and the cavity 3 extends along a circular trajectory centered on the mounting hole 21. Thus, the cavity 3 extending along a circular trajectory centered on the mounting hole 21 further enhances the strength of the substrate 1 in the area where the limiter is mounted.

[0038] For example, the mounting hole 21 can be a square hole, a round hole, or an irregularly shaped hole, as long as it allows for the installation of the limit switch.

[0039] In one embodiment of this disclosure, see Figure 2 The substrate 1 has a mating hole 11, which communicates with and is coaxially arranged with the mounting hole 21. The shape of the mating hole 11 can be the same as that of the mounting hole 21, but the diameter of the mating hole 11 is smaller than that of the mounting hole 21. The cavity 3 is a closed annular cavity 3. Thus, when installing the limiter, bolts can be passed through the mounting hole 21 and the mating hole 11 to position the limiter, facilitating its installation. The annular closed cavity 3 provides higher strength to the limiter.

[0040] In one embodiment of this disclosure, see Figure 1 and Figure 3The reinforcing plate 2 has at least two positioning holes 22, which are located on both sides of the mounting hole 21 and are used to connect to the limiter by bolts.

[0041] In one embodiment of this disclosure, see Figure 1 and Figure 3 The reinforcing plate 2 has multiple second welding holes 23, and the base plate 1 and the reinforcing plate 2 are welded through the multiple second welding holes 23. In this way, the forming difficulty of the reinforcing plate 2 and the base plate 1 is reduced, the weight of the door reinforcement assembly is reduced, and the strength of the door reinforcement assembly is improved.

[0042] In one embodiment of this disclosure, see Figure 1 and Figure 4 The door reinforcement assembly also includes a mounting plate 4. The mounting plate 4 is stacked on and connected to the base plate 1. The mounting plate 4 and the reinforcing plate 2 are located on the same side of the base plate 1. The mounting plate 4 is used to mount the hinge. Thus, by integrating the mounting plate 4 and the reinforcing plate 2 onto the base plate 1, the hinge is connected to the mounting plate 4, and the limiter is connected to the reinforcing plate 2, improving the compactness and strength of the entire structure. In some other embodiments of this disclosure, the mounting plate 4 and the reinforcing plate 2 may be located on opposite sides of the base plate 1.

[0043] In one embodiment of this disclosure, see Figure 1 The substrate 1 has a mounting groove 12, and the mounting plate 4 is fixed in the mounting groove 12. In other words, the thickness of the area on the substrate 1 where the mounting plate 4 is mounted is smaller than the thickness of other areas, so as to reduce the thickness and weight of the door reinforcement assembly.

[0044] In one embodiment of this disclosure, see Figure 1 and Figure 4 The mounting plate 4 includes a mounting portion 41 and a positioning portion 42 disposed on a surface away from the substrate 1. The mounting portion 41 is disposed at the bottom of the mounting groove 12, and the positioning portion 42 has a threaded hole extending into the mounting portion 41. The threaded hole is used to connect with a hinge via a threaded element. In this way, the hinge is easily mounted on the positioning portion 42 by the engagement of the threaded element and the threaded hole.

[0045] In one embodiment of this disclosure, see Figure 4 The mounting part 41 includes an integrally connected base plate 411 and a side plate 412. The side plate 412 extends along the edge of the base plate 411 and forms a receiving cavity with the base plate 411, and the positioning part 42 is located in the receiving cavity. In this way, the side plate 412 can protect the positioning part 42.

[0046] In one embodiment of this disclosure, see Figure 1 and Figure 4The mounting portion 41 has multiple first welding holes 43, and the substrate 1 is welded to the mounting portion 41 through the multiple first welding holes 43. The edge of the substrate 1 is welded to the inner panel of the door, and the weld is located at the edge of the substrate 1. In this way, the mounting plate 4 is welded to the substrate 1 through the first welding holes 43, and then the edge of the substrate 1 is welded to the inner panel of the door, avoiding the problem of exposed weld points caused by directly welding the mounting plate 4 to the inner panel of the door, improving the appearance quality of the door and reducing costs.

[0047] In one embodiment of this disclosure, see Figure 1 The substrate 1 is provided with at least one reinforcing rib 13. For example, the number of reinforcing ribs 13 can be one, two, three, etc. Some of the reinforcing ribs 13 can be located between the mounting plate 4 and the reinforcing plate 2 in order to improve the strength of the substrate 1.

[0048] In one embodiment of this disclosure, see Figure 1 The substrate 1 is provided with at least one weight-reducing hole 14. For example, the number of weight-reducing holes 14 can be one, two, three, etc., in order to further reduce the weight of the door reinforcement assembly.

[0049] Other embodiments of this disclosure will readily occur to those skilled in the art upon consideration of the specification and practice of the invention disclosed herein. This application is intended to cover any variations, uses, or adaptations of this disclosure that follow the general principles of this disclosure and include common knowledge or customary techniques in the art not disclosed herein. The specification and examples are to be considered exemplary only, and the true scope and spirit of this disclosure are indicated by the appended claims.
