The traditional solution is to set a reinforcing plate on the door inner plate to strengthen the structural strength of the door inner plate, thereby improving the structural strength of the entire door assembly.

[0003] Some existing reinforcing plates, such as Figure 1 the structure shown, have four steel stampings as reinforcing plates 1b set at the center to enhance the load-bearing capacity of the door assembly. These reinforcing plates 1b are connected to the door inner plate 1a in a specific manner to disperse and withstand the stress generated by the load of the spare tire.

[0032] The relational terms such as "first" and "second" are only used to distinguish one component from another component with the same name, and do not necessarily require or imply any such actual relationship or order between the components.

[0033] Specifically, when the spare tire (weight about 30kg) is installed on the door assembly, the door assembly will be obviously deformed due to the insufficient stiffness of the inner area of the door assembly. This deformation not only affects the appearance quality of the vehicle, but also may cause the door assembly lock and the vehicle body lock to be unable to align, so that the door assembly cannot be smoothly locked when closing. The occurrence of this problem not only reduces the practicability and safety of the vehicle, but also may cause unnecessary trouble and loss to the owner.

[0034] Therefore, in view of the problems and deficiencies in the existing inner door panel area structure design, it is necessary to propose an improved inner door panel area structure design scheme to improve the overall stiffness and carrying capacity of the door assembly and ensure that no sagging deformation occurs when the spare tire is equipped and the like.

[0036] As shown in the drawings, the present application provides a side opening type vehicle door assembly, which refers to a rotating shaft of the vehicle door assembly extending in the height direction during the process of opening the door, and arranged on one side of the vehicle in the width direction. The vehicle door assembly further comprises a plurality of hinges capable of being connected with the vehicle body, so as to realize the rotation of the vehicle door assembly relative to the vehicle body.

[0037] The side opening type vehicle door assembly comprises an inner door panel 3 and an outer door panel, the edges of the inner door panel 3 and the outer door panel are fixedly connected, and a containing cavity is formed therebetween, and a reinforcing plate 4 is contained in the containing cavity. The reinforcing plate 4 is fixedly connected to the inner door panel 3, and partially conforms to the shape of the inner door panel 3 in some areas, so as to reinforce the inner door panel 3. Specifically, the inner door panel 3 has a bearing area, and the reinforcing plate 4 covers the bearing area; the main function of the bearing area is to support and disperse the force and weight generated after the tire is installed.

[0038] In a specific manner, the inner door panel 3 is further provided with a window mounting area 32, and the bearing area is located on the lower side of the window mounting area 32. That is, the reinforcing plate 4 covers the part on the lower side of the window mounting area 32 in this embodiment. By arranging the bearing area on the lower side of the window mounting area 32, the strength can be guaranteed while avoiding occupying the space of the window, which is beneficial to the maximization of the area of the window.

[0039] Of course, the reinforcing plate 4 can also partially extend on the side, top side or around the window mounting area 32 in addition to being arranged on the part on the lower side of the window mounting area 32.

[0040] The reinforcing plate 4 is further provided with a connecting hole 44, and the connecting hole 44 is adapted to a connecting piece to fixedly connect a spare tire rack. The side opening type vehicle door assembly further comprises a buffer piece 43, and the buffer piece 43 is fixedly connected to the reinforcing plate 4. The outer door panel is provided with a hole corresponding to the buffer piece 43, and the buffer piece 43 extends outward through the hole and forms a buffering effect on the tire mounted on the tire rack.

[0041] The specific structure of the reinforcing plate 4 in the present application will be described below.

[0042] In the technical solution of the present application, the traditional split structure of the reinforcing plate is changed to an integrally formed reinforcing plate 4, which can improve the overall reinforcing effect of the reinforcing plate 4. In addition, the reinforcing plate 4 can be cast from cast aluminum material, and the integrally formed reinforcing plate 4 only needs to develop one set of die casting mold, and the related mold cost can be significantly reduced.

[0043] In the example as shown, the inner door panel 3 also has a plurality of hinge mounting areas 31 distributed upward and downward along the vehicle height direction, where the hinge mounting area 31 is an area adapted to the hinge described above for mounting the hinge. The reinforcing plate 4 is fitted and fixedly connected with the hinge mounting area 31.

[0044] By adopting the technical solution in the present application, the reinforcing plate 4 extends to the hinge mounting area 31 of the inner door panel 3 while covering the bearing area to locally reinforce the area, and is fitted and fixedly connected with the hinge mounting area 31, so that the structural stress can be directly transmitted to the hinge mounting area 31, thereby effectively preventing the sagging deformation of the side-opening type vehicle door.

[0045] The reinforcing plate 4 includes a plate body 41, and the plate body 41 is provided with a first flange 42, which is folded out of the plate body 41 and fitted to the corresponding hinge mounting area 31. The first flange 42 is at least partially conformally fitted to the hinge mounting area 31, which ensures the integration of the reinforcing plate 4 structure and also increases the connection strength of the first flange 42.

[0046] In the foregoing embodiments, the first flange 42 has a plurality of mounting positions. The plurality of mounting positions are divided into a first type of mounting position 421 and a second type of mounting position 422, and the mounting positions correspond to the connection holes. The hinge mounting area 31 is provided with a plurality of hinge connecting pieces 5 to realize the fixation of the hinge. The reinforcing plate 4 also includes a reinforcing plate connecting piece. The first type of mounting position 421 is adapted to the hinge connecting piece 5, and the second type of mounting position 422 is adapted to the reinforcing plate connecting piece.

[0047] In a specific way, the hinge connecting piece 5 refers to a screw rod and a nut adapted to the hinge, the first type of mounting position 421 is provided with a first type of hole, the first type of hole is adapted to the screw rod and accommodates the screw rod to pass through, and then the first flange 42 is locked to the hinge mounting area 31 by the nut. The reinforcing plate 4 connecting piece is a rivet, the second type of mounting position 422 is provided with a second type of hole adapted to the rivet, and the hinge mounting area 31 is also provided with a second type of hole, and the first flange 42 is fixedly connected to the hinge mounting area 31 by the rivet riveting adapted to the second type of hole.

[0048] The second type of mounting position 422 is located below the first type of mounting position 421. In the embodiment, by arranging the two types of mounting positions, the original hinge connecting piece 5 can be used to connect the reinforcing plate 4 and the hinge mounting area 31, so that the stress is transmitted to the hinge mounting area 31, and the hinge mounting area 31 is locally reinforced. In addition, the second type of mounting position 422 is arranged, and the arrangement of the second type of mounting position 422 increases the connecting points between the hinge mounting area 31 and the first flange 42, avoids stress concentration on the hinge connecting piece 5, and further improves the structural strength of the area.

[0049] In the foregoing embodiment, the plate body 41 extends along the width direction of the vehicle, the first flange 42 is arranged on the right side of the plate body 41, the left side extends to the area of the plate body 41 where the lock and the door handle are arranged, the upper side extends to the lower side of the window mounting area 32, and the second flange is formed by being conformally attached to the area to form a rivet connection. The lower part of the plate body 41 extends to the bottom of the inner door panel 3 and is conformally attached to the part to form a rivet connection.

[0050] In other embodiments, the plate body 41 is further provided with two reinforcing package groups 413 distributed along the width direction of the vehicle. The reinforcing package groups 413 are used to fix the spare tire frame. Each reinforcing package group 413 includes two reinforcing bosses 413a distributed along the height direction of the vehicle. The reinforcing bosses 413a protrude from the side where the inner door panel 3 is located to the side where the outer door panel is located in the length direction of the vehicle, forming a prism structure or a column structure. The table surface of each reinforcing boss 413a abuts against the outer door panel. In this way, the reinforcing bosses 413a support the space between the inner door panel 3 and the outer door panel in the length direction of the vehicle, further improving the structural strength of the side-hinged door.

[0051] In the above embodiment, as an optional way, the two reinforcing package groups 413 are symmetrically distributed with respect to the vertical center line of the inner door panel 3. In this way, the spare tire frame forms connecting points on both sides of the vertical center line of the inner door panel 3, avoiding deformation of the inner door panel 3 itself.

[0052] Further, in order to avoid uneven stress or relative deformation of the two reinforcing package groups 413, the plate body 41 further includes a reinforcing vertical rib 411 which coincides with the vertical center line of the inner door panel 3. In this way, the reinforcing vertical rib 411 can further reinforce the vertical center line of the inner door panel 3.

[0053] In the example as shown in the figure, the weight-reducing hole 414 is arranged between the two reinforcing bosses 413a of the same reinforcing package 413, the weight-reducing hole 414 penetrates the reinforcing plate 4 along the thickness direction of the reinforcing plate 4, and the weight-reducing hole 414 is symmetrically distributed relative to the vertical center line. By adopting the weight-reducing hole 414 in the scheme, the reinforcing plate 4 can be greatly lightened, and the arrangement of the weight-reducing hole 414 between the two reinforcing bosses 413a and the symmetric distribution relative to the vertical center line ensure that the reinforcing plate 4 is greatly lightened without affecting the reinforcing effect of the reinforcing plate 4 on the inner door panel 3.

[0054] In some other optional embodiments, the reinforcing package 413 located on the side close to the hinge mounting area 31 is defined as an inner reinforcing package, and the side-hinged door assembly further comprises a reinforcing cross rib 412, one end of which is connected with the reinforcing package 413 and the other end of which extends to the part where the plate body 41 and the first flange 42 meet. In this way, local reinforcement is formed on the transmission path of the load borne by the side-hinged door assembly, and the effect of resisting sagging and deformation of the side-hinged door assembly is further improved.

[0055] In another aspect of the present application, a vehicle is also provided, which comprises a spare tire bracket and the aforementioned side-hinged door assembly, and the spare tire bracket is fixedly connected with the side-hinged door assembly. By improving the structure of the side-hinged door assembly, the sagging and deformation of the side-hinged door assembly are avoided.

[0056] Compared with the conventional scheme, the present application has the following advantages:

[0057] Firstly, by adopting the one-piece door assembly in the present application, an effective overall reinforcing effect is formed. When the spare tire and the like are borne, the stress can be uniformly distributed, so that excessive deformation is avoided in some local areas.

[0058] Secondly, the reinforcing plate 4 is directly connected with the hinge connection area of the door assembly. The hinge is a key component for connecting the door assembly with the vehicle body, and it bears the important task of transmitting the force borne by the door assembly to the vehicle body. In the present application, by forming an effective connection path between the reinforcing plate 4 and the hinge of the door assembly, the stress of the structure of the inner door panel 3 is smoothly transmitted to the hinge position. In this way, the overall rigidity of the door assembly is further improved, and sagging and deformation of the door assembly are avoided when the spare tire and the like are borne.

[0059] The principle and implementation mode of the present application are described by using specific examples in the present document, and the above description of the examples is only used to help understand the core idea of the present application. It should be pointed out that, for ordinary skilled persons in the technical field, some improvements and modifications can be made to the present application without departing from the principle of the present application, and these improvements and modifications also fall within the protection scope of the claims of the present application.
