[0035] The following will describe the implementation methods of the present application with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present application from the contents disclosed in this specification. The present application can also be implemented or applied through other different specific implementation methods, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present application. It should be understood that the preferred embodiments are only for illustrating the present application, not for limiting the scope of protection of the present application.

[0036] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present application, and thus the drawings only show components related to the present application rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed at will, and the component layout may also be more complicated.

[0037] In the description of the present application, “plurality” means two or more.

[0038] Combine the following Figure 1-Figure 3 The vehicle door outer panel assembly of the first embodiment of the present application is described, and the vehicle door outer panel assembly includes an outer panel body 10, a first reinforcement plate 20 and a second reinforcement plate 30. The vehicle door outer panel assembly can be located below a vehicle window (not shown) of a vehicle door assembly 100.

[0039] Specifically, if Figure 1 As shown, the first reinforcing plate 20 is connected to the inner side of the outer panel body 10, and the first reinforcing plate 20 and the outer panel body 10 jointly define a cavity, which is located below the vehicle window, and the cavity is arranged adjacent to the lower end of the vehicle window to ensure that the cavity wall of the cavity can play a role in supporting the vehicle window and the support reliability is good; the second reinforcing plate 30 is arranged between the first reinforcing plate 20 and the outer panel body 10, for example, the second reinforcing plate 30 is arranged between the first reinforcing plate 20 and the outer panel body 10 as shown in FIG. Figure 1 In the inner and outer directions (ie, the left and right directions of the vehicle) shown, the second reinforcing plate 30 divides the cavity into a plurality of sub-cavities.

[0040] exist Figure 1 In the example, the thickness of the main body of the first reinforcing plate 20 and the main body of the second reinforcing plate 30 can be the same at all places. The upper edge of the first reinforcing plate 20 is located above the upper edge of the second reinforcing plate 30, and the lower edge of the second reinforcing plate 30 is located below the lower edge of the first reinforcing plate 20, so that the first reinforcing plate 20 and the second reinforcing plate 30 are respectively installed and connected with the outer plate body 10, so as to ensure the installation reliability of the first reinforcing plate 20 and the outer plate body 10 and the installation reliability of the second reinforcing plate 30 and the outer plate body 10, so as to improve the rigidity of the sub-cavity.

[0041] It is understandable that the structural rigidity of the door assembly 100 directly affects the installation reliability of the window installed on the upper end of the door assembly 100 and the supporting stability of the window by the door assembly 100, especially when the door assembly 100 is a frameless door. In the prior art, since the frameless door has no window frame, the structural strength of the door assembly where the window is installed deteriorates, which not only affects the structural strength and anti-collision performance of the vehicle, but also causes the installation reliability of the window and the supporting stability of the window by the door assembly to deteriorate. If the method of increasing the material thickness is adopted to improve the structural strength at the window, it is necessary to increase the material thickness of the entire door outer panel or reinforcement, resulting in a significant increase in cost.

[0042] Thus, the reinforcing plate is split into the first reinforcing plate 20 and the second reinforcing plate 30 and a plurality of sub-cavities are defined. The cavity walls of the plurality of sub-cavities can support the window below the window. Compared with the flat reinforcing plate, there is no need to increase the material thickness of the reinforcing plate. It can provide higher rigidity with less material added to improve the rigidity at the window sill position, so that the installation of the window is more reliable and the support for the window is more stable. In addition, it can be more conducive to absorbing energy and improving the anti-collision performance. Moreover, compared with the setting of a single cavity, the second reinforcing plate 30 can act as a reinforcing rib in the cavity, and the setting of multiple sub-cavities can disperse stress and load, which can further improve the rigidity of the door outer panel assembly, the installation reliability of the window and the support stability.

[0043] It is understandable that in order to improve the rigidity of the sub-cavity, ensure the stability of the installation and support of the vehicle window, and improve the anti-collision performance of the door assembly 100, multiple sub-cavities can be set as closed cavities. The specific setting of the cavity can be a semi-closed cavity or a completely closed cavity. The above situation can be specifically set according to the actual situation, and it is only necessary to ensure that the sub-cavity is a closed cavity.

[0044] In some embodiments, Figure 1 As shown, the multiple sub-cavities include a first cavity 40 and a second cavity 50. The first cavity 40 is defined by the first reinforcing plate 20 and the second reinforcing plate 30, and the second cavity 50 is defined by the first reinforcing plate 20, the second reinforcing plate 30 and the outer panel body 10. The first cavity 40 and the second cavity 50 can form a double-cavity structure. Such a configuration can facilitate the configuration of the shapes and positions of the multiple sub-cavities according to actual conditions, so as to take into account different requirements for improving performance. Optionally, the second cavity 50 can be configured as a long and narrow cavity and a portion of the second cavity 50 can be located outside the first cavity 40 (for example, outside along the left-right direction of the vehicle), so that the upper half of the second cavity 50 can more effectively support the vehicle window, and the lower half of the second cavity 50 can more effectively improve the anti-collision performance.

[0045] In some embodiments, Figure 1 As shown, at least a portion of the first cavity 40 and at least a portion of the second cavity 50 are arranged relative to each other in the up-down direction. For example, the entire first cavity 40 can be located below the upper half of the second cavity 50. In this way, on the one hand, it can be beneficial to improve the vertical rigidity of the door outer panel assembly to improve the stability of the window support; on the other hand, the space below the first cavity 40 can be reasonably utilized to prevent the situation in which the door outer panel assembly becomes thicker due to the occupation of the space in the inside-outside direction. Of course, in other embodiments, at least a portion of the first cavity 40 and at least a portion of the second cavity 50 can also be arranged relative to each other in the left-right direction, and can be specifically arranged according to actual needs, which is not limited here. Furthermore, at least a portion of the first cavity 40 and at least a portion of the second cavity 50 can also be arranged relative to each other in the left-right direction and relative to each other in the up-down direction at the same time.

[0046] In some embodiments, Figure 1 As shown, the first reinforcing plate 20 includes a first protruding section 21, and the second reinforcing plate 30 includes a second protruding section 31. The first protruding section 21 and the second protruding section 31 together define a first cavity 40. The first protruding section 21 is a part of the first reinforcing plate 20 that protrudes in a direction away from the outer plate body 10, and the second protruding section 31 is a part of the second reinforcing plate 30 that protrudes in a direction toward the outer plate body 10. In this way, it is helpful to resist external forces and prevent the first reinforcing plate 20 or the second reinforcing plate 30 from deforming, so as to further improve the support stability of the vehicle window.

[0047] In some embodiments, Figure 1 As shown, the first reinforcing plate 20 further includes a first connecting section 22, which is connected to the first protruding section 21, and the second reinforcing plate 30 includes a second connecting section 32, which is connected to the second protruding section 31, and the first connecting section 22 and the second connecting section 32 are attached to each other. For example, the first connecting section 22 and the second connecting section 32 can be two correspondingly arranged, one of the first connecting sections 22 is connected to the upper end of the first protruding section 21, and the other first connecting section 22 is connected to the lower end of the first protruding section 21, one of the second connecting sections 32 is connected to the lower end of the second protruding section 31, and the other second connecting section 32 is connected to the lower end of the second protruding section 31. In this way, the load-bearing capacity of the first cavity 40 can be improved, the closed setting of the first cavity 40 is convenient, and the positioning and installation of the first reinforcing plate 20 and the second reinforcing plate 30 can be convenient.

[0048] like Figure 1As shown, the first protruding section 21 may include a first sub-section 211 and a second sub-section 212, the first sub-section 211 and the second sub-section 212 are connected to each other and arranged at an angle to jointly construct the first protruding section 21, the first sub-section 211 is connected to one of the first connecting sections 22, and the second sub-section 212 is connected to another first connecting section 22, wherein the first sub-section 211 can extend in the same direction as the first connecting section 22 connected thereto, so as to facilitate the connection between the second reinforcing plate 30 and the first reinforcing plate 20, and to facilitate the adjustment of the assembly position and improve the assembly accuracy. The second protruding section 31 may include a third sub-section 311, a fourth sub-section 312 and a fifth sub-section 313, the third sub-section 311, the fourth sub-section 312 and the fifth sub-section 313 are connected in sequence and arranged at an angle to jointly construct the second protruding section 31, the third sub-section 311 is connected to one of the second connecting sections 32, and the fifth sub-section 313 is connected to another second connecting section 32, and such an arrangement can help improve the load-bearing capacity of the cavity wall of the first cavity 40. The fourth sub-segment 312 can be arranged parallel to the outer panel body 10 and the fourth sub-segment 312 can construct a part of the inner wall of the second cavity 50. Such an arrangement can facilitate the first cavity 40 and the second cavity 50 to jointly absorb the energy of side impact and improve the anti-collision performance.

[0049] In some embodiments, the first connecting section 22 and the second connecting section 32 are connected by welding. Figure 2 and Figure 3 As shown, the second connection section 32 has a plurality of first welding areas 33 and a plurality of second welding areas 34, the plurality of first welding areas 33 are spaced and evenly arranged along the width direction of the door outer panel assembly (that is, the length direction of the vehicle), the plurality of second welding areas 34 are spaced and evenly arranged along the width direction of the door outer panel assembly (that is, the length direction of the vehicle), the first welding area 33 is formed in the second connection section 32 located above the second protruding section 31, and the second welding area 34 is formed in the second connection section 32 located below the second protruding section 31. Thus, by welding the first connection section 22 and the second connection section 32, the installation reliability of the first reinforcement plate 20 and the second reinforcement plate 30 can be improved, and welding at the first connection section 22 and the second connection section 32 that are arranged in contact can further improve the rigidity and sealing reliability of the first cavity 40.

[0050] In some embodiments, Figure 2 As shown, the second reinforcing plate 30 has a door handle mounting portion, and the outer plate body 10 has a door handle avoidance hole 11, and the door handle avoidance hole 11 is arranged opposite to the door handle mounting portion. A door handle (not shown) can be installed on the door handle mounting portion and has a use state and a hidden state. When the door handle is in the use state, the door handle extends from the door handle avoidance hole 11; when the door handle is in the hidden state, the door handle is hidden in the door handle avoidance hole 11.

[0051] In some embodiments, Figure 1 As shown, the second reinforcing plate 30 is bonded to the outer plate body 10 by means of an expansion adhesive 60; and / or the first reinforcing plate 20 is connected to the outer plate body 10 by means of an edge wrapping. Figure 1 In the example, the second reinforcing plate 30 is bonded to the lower half of the outer panel body 10 by means of the expansion adhesive 60. The bonding method of the expansion adhesive 60 can facilitate uniform stress distribution, and there is no need for welding to prevent the welding points from being exposed, so as to improve the aesthetics of the lower half of the outer panel body 10 exposed to the outside.

[0052] exist Figure 1 In the example, the second reinforcing plate 30 is connected to the upper end of the outer plate body 10 by the hemming. That is, one of the second reinforcing plate 30 or the outer plate body 10 may have a flange 12, so that the flange 12 can be wrapped around the outer side of the other of the second reinforcing plate 30 or the outer plate body 10 to improve the structural rigidity and the connection stability of the two. Among them, the outer plate body 10 may have a flange 12 (in the initial state, the flange 12 can be bent ninety degrees), and after the second reinforcing plate 30 and the outer plate body 10 are placed in the preset installation position, the flange 12 can be bent toward the direction of the second reinforcing plate 30 until the flange 12 is connected to the second reinforcing plate 30 to ensure the installation stability of the two. The assembly method set in this way can be more conducive to meeting the precision requirements of the installation of the flange 12 of the outer plate body 10 and the second reinforcing plate 30. In addition, the setting of the flange 12 can further improve the rigidity of the adjacent window sill of the door outer panel assembly 100, improve the installation stability of the window and the support effect on the window.

[0053] In some embodiments, Figure 1 As shown, the second reinforcing plate 30 has an expansion glue limiting groove 35. The expansion glue limiting groove 35 can be used to accommodate the expansion glue 60 for positioning and bonding, and is conducive to improving the consistency of the product and the sealing stability of the second cavity 50.

[0054] The vehicle door assembly 100 of the second embodiment of the present application includes a vehicle door outer panel assembly and a vehicle door inner panel 70, wherein the vehicle door inner panel 70 is connected to the inner side of the vehicle door outer panel assembly. Figure 3 As shown, the vehicle door outer panel assembly can be welded to the vehicle door inner panel 70 at a plurality of third welding regions 23. Thus, the vehicle door outer panel assembly has high rigidity, good structural strength, good supporting effect on the vehicle window, and good safety performance.

[0055] Combine the following Figure 1-Figure 3The assembly sequence of the vehicle door assembly 100 of the embodiment of the present application is described as follows: the first reinforcing plate 20 and the second reinforcing plate 30 are welded into a whole at the first welding area 33 and the second welding area 34, and jointly define a first cavity 40, and then the two ends of the vehicle door inner panel 70 are welded to the third welding area 23 of the first reinforcing plate 20, and finally, the second reinforcing plate 30 is coated with expansion glue 60 and then bonded to the outer panel body 10, and then connected to the first reinforcing plate 20 by the flange 12 of the outer panel body 10, and the first reinforcing plate 20, the second reinforcing plate 30 and the outer panel body 10 jointly define a second cavity 50.

[0056] The vehicle of the third embodiment of the present application includes the door assembly 100 as described above. As a result, higher rigidity can be provided while adding less material, so that the installation of the window is more reliable and the support of the window is more stable. In addition, it can be more conducive to absorbing energy and improving collision resistance. Moreover, compared with the setting of a single cavity, the second reinforcing plate 30 can play the role of a reinforcing rib, and the setting of multiple sub-cavities can disperse stress and load, which can further improve the rigidity of the door outer panel assembly, the installation reliability and support stability of the window, and the structural strength and safety performance of the vehicle are better.
