[0001] This invention generally relates to the field of vehicle components, and more specifically, to a door assembly and a vehicle including such a door assembly. Background Technology

[0002] In the car door structure, the inner door panel is a key load-bearing component, requiring separate installation of the rearview mirror and door sealing strip. Currently, a completely separate installation scheme is commonly used, where the rearview mirror is independently installed to the outer side of the inner door panel using a special bracket and bolts, while the door sealing strip needs to be installed separately to the edge of the inner door panel and window frame using a clip structure or adhesive.

[0003] The existing design has several shortcomings: Structurally, especially at the front end (corner) of the door seal, the two completely independent connection systems not only increase the number of parts but also complicate material management and production line assembly; in terms of process implementation, it requires two separate positioning and installation steps, which reduces production efficiency and may lead to accumulated dimensional deviations due to multiple installations; and in terms of reliability, the sealing systems of the two components are prone to mismatch under long-term vehicle vibration conditions, resulting in wind noise and seal failure. This traditional completely separate installation scheme cannot meet the stringent requirements of today's automotive industry for integration, efficiency, and quality stability.

[0025] The implementation and use of specific embodiments are discussed in detail below. However, it should be understood that the specific embodiments discussed are merely illustrative of particular ways of implementing and using the invention, and are not intended to limit the scope of the invention.

[0026] In this specification and accompanying drawings, the descriptions of the structural positions of various components, such as "up," "down," "top," "bottom," "vertical," and "horizontal," are not absolute but relative. These directional descriptions are appropriate when the components are in the positions shown in the figures, but they should be changed accordingly when the positions of the components change. Furthermore, "inner" and "outer" are defined with reference to the vehicle's interior and exterior directions; for example, "inner side" indicates the side facing the interior of the vehicle, and "outer side" indicates the side facing the exterior of the vehicle.

[0027] "Front" and "rear" are defined with reference to the vehicle's X-axis forward and backward direction. In addition, the X-axis represents the vehicle's longitudinal direction (i.e., the vehicle's direction of travel), the Y-axis represents the vehicle's lateral direction (i.e., the left-right direction at a 90-degree angle relative to the direction of travel), and the Z-axis represents the vehicle's vertical direction (i.e., the up-down direction).

[0028] In this specification, unless otherwise expressly specified and limited, terms such as "installation" and "connection" should be interpreted broadly, for example, referring to a fixed connection, a detachable connection, or an integral connection. Those skilled in the art can understand the specific meaning of these terms in this specification according to the specific circumstances.

[0029] A preferred embodiment of the door assembly according to the present invention will now be described in detail with reference to the accompanying drawings.

[0030] like Figure 1 and Figure 2 As shown, the door assembly according to the present invention includes an inner door panel 1, a rearview mirror base 2, and a door sealing strip 3.

[0031] The inner door panel 1 includes a mounting portion 11 at its front end for mounting a rearview mirror base 2. Preferably, the mounting portion 11 is provided with a first mounting hole 111. It is understood that the inner door panel 1 includes a window frame, and a door sealing strip 3 (also referred to as an automotive glass guide channel) is installed to the inner door panel 1 and the edge of the window frame to prevent rainwater, dust, and other foreign objects from entering the vehicle interior.

[0032] like Figures 3 to 5 As shown, the rearview mirror base 2 is connected to the mounting part 11 on the outside of the inner panel 1 of the door, and includes a generally plate-shaped body 21 and a fixing part 22. The body 21 includes a bottom wall 211 and a front side wall 212 extending from the bottom wall 211. The fixing part 22 protrudes from the edge of the front side wall 212 and forms a boss structure. The boss structure includes a connecting wall 222 with a second mounting hole 223.

[0033] like Figure 5 and Figure 6 As shown, a first connector 5 is provided on the fixing part 22 of the rearview mirror base 2. The first connector 5 includes a clamping part 51 and a connecting part 52. The clamping part 51 includes a first clamping piece 514 and a second clamping piece 515 that clamp the connecting wall 222, and each clamping piece is provided with a first through hole 511. The connecting part 52 is a cylindrical structure extending from the second clamping piece 515. Fasteners can pass through the first through hole 511 of the clamping part 51 and the second mounting hole 223 of the connecting wall 222, and extend into and connect to the connecting part 52. Preferably, the connecting part 52 is provided with an internal thread, and the fastener is provided as a screw 7 that mates with the internal thread. Preferably, the material of the first connector 5 is polyoxymethylene (POM). Polyoxymethylene (POM) has high wear resistance, high strength and dimensional stability, creep resistance, ensures reliable thread fastening, is resistant to chemical corrosion, and reduces the risk of wear and loosening. The first connector 5 is configured as a component independent of the rearview mirror base 2, which reduces the manufacturing requirements of the rearview mirror base 2 mold and lowers the cost. According to another embodiment, the first connector 5 can also be integrally formed on the fixing part 22, for example, by providing a threaded hole in the connecting wall 222 of the fixing part 22. According to some variations, a metal nut can also be embedded in the fixing part 22.

[0034] like Figure 1 and Figure 2As shown, the door sealing strip 3 includes an A-pillar sealing strip 31, a B-pillar sealing strip 32, a rearview mirror front sealing strip 33 extending downward and forward from the A-pillar sealing strip 31, a rearview mirror rear sealing strip 34 extending downward and approximately vertically from the A-pillar sealing strip 31, and a longitudinal sealing strip 35 connecting the A-pillar sealing strip 31 and the B-pillar sealing strip 32. The door sealing strip 3 also includes a first triangular angle 36 connecting the rear end of the longitudinal sealing strip 35 and the upper end of the B-pillar sealing strip 32, and a generally rectangular second angle 37 connecting the lower end of the rearview mirror front sealing strip 33. The A-pillar sealing strip 31, B-pillar sealing strip 32, and longitudinal sealing strip 35 are sealed to the vehicle body sheet metal by compression through their upper lips when the door is closed, and sealed to the vehicle window glass by compression through their lower lips. The rearview mirror front sealing strip 33 is sealed to the vehicle body sheet metal by compression through its upper lip when the door is closed, and sealed to the rearview mirror base 2 by compression through its lower lip. The rear sealing strip 34 of the rearview mirror is sealed by pressing against the rearview mirror base 2 through the front lip and by pressing against the window glass through the rear lip. The end 371 of the second corner 37 is connected to the inner side of the door inner panel 1 and is provided with a second through hole 311.

[0035] like Figure 7 and Figure 8 As shown, the second connector 6 is, for example, injection-molded and embedded into the end 371 of the second corner 37, and includes a main body portion 60 connected to the inner door panel 1 and a bushing 61 embedded in the second through hole 311, so that the head of the screw 7 can abut against the bushing 61. Preferably, the material of the second connector 6 is a polyethylene composite material with 30% glass fiber added, namely PE GF30. The lightweight properties of PE GF30 material can reduce the weight of the second connector 6 and enhance mechanical properties (such as impact resistance and corrosion resistance), thus improving durability. In addition, the high stiffness and shock absorption properties of PE GF30 support the axial force of the screw 7 and buffer the vibration impact between the sealing strip and the inner panel, thus extending the service life.

[0036] like Figure 2 , Figure 4 and Figure 5 As shown, along the thickness direction of the inner door panel 1, from the inside to the outside, the second through hole 311, the first mounting hole 111, the first through hole 511, and the second mounting hole 223 are aligned sequentially to allow the screw 7 to pass through. This design allows the screw 7 to pass through all components in approximately the Y direction, forming a through connection. Therefore, at this location, the rearview mirror base 2 and the door sealing strip 3 are simultaneously connected to the inner door panel 1, saving installation space.

[0037] In other words, in the door assembly according to the present invention, the mounting portion 11 of the inner door panel 1 is clamped between the rearview mirror base 2 and the end 371 of the door sealing strip 3 by screws 7 that cooperate with the first connector 5 and the second connector 6. That is, the inner door panel 1, as an intermediate layer, is tightly clamped by the rearview mirror bases 2 on both sides and the end 371 of the door sealing strip 3, forming a stable sandwich-style assembly structure.

[0038] In traditional solutions, the rearview mirror base 2 and the door sealing strip 3 need to be fixed to the inner door panel 1 at this location using separate connectors. This occupies more space on the inner door panel 1, and the installation process is cumbersome, prone to component misalignment or loosening. The door assembly of this invention, on the one hand, reduces the number of parts, space occupation, and material and mold costs by using aligned mounting holes and a common screw 7, while simplifying supply chain management. On the other hand, it allows for simultaneous installation of the rearview mirror base 2 and sealing strip 3 at this location, requiring only a single screw 7 fixing operation, eliminating the cumbersome step-by-step installation process, shortening assembly time, and reducing labor costs.

[0039] The technical content and features of the present invention have been disclosed above. However, it is understood that those skilled in the art can make various changes and improvements to the above-disclosed concept under the creative idea of ​​the present invention, but all of these shall fall within the protection scope of the present invention.

[0040] The above description of the embodiments is exemplary and not restrictive, and the scope of protection of the present invention is determined by the claims.
