Description

[Technical Field]

[0001] The present application relates to the field of vehicle technology, and in particular to vehicle door assemblies, vehicle doors, and vehicles. [Background technology]

[0002] 2. Description of the Related Art With economic development and continuous improvement of living standards, the use rate of vehicles (such as new energy vehicles and intelligent vehicles) is increasing, and users are also increasing their requirements for vehicle usage experience.

[0003] A vehicle door, an important part of a vehicle, can provide a passage for users to enter and exit the vehicle. In the process of getting in and out of a vehicle, users need to open and close the vehicle door. When the vehicle door is opened, the door latch of the vehicle door is unlocked by a striker on the vehicle body. When the vehicle door is closed, the door latch of the vehicle door engages with the striker on the vehicle body.

[0004] The inner door panel can be used not only as a decorative part of the vehicle door but also as a bearing part for the door latch. Generally, when the door latch is fixed to the inner door panel, the draft angle of the door latch mounting surface of the door latch, which is connected to the inner door panel, is small so that the door latch can meet the door latch arrangement requirements and facilitate the unlocking and engaging process between the door latch and the striker. Therefore, when the door latch mounting surface is attached to the surface of the door latch mounting area of ​​the inner door panel, the draft angle of the surface of the door latch mounting area is also small. When the stamping depth of the surface of the door latch mounting area of ​​the inner door panel in the forming direction of the door latch mounting area of ​​the inner door panel is large, if the draft angle is too small, punching cracks of the inner door panel are likely to occur during the stamping process. Summary of the Invention

[0005] The present application provides a vehicle door assembly, vehicle door, and vehicle that increases the draft angle in the door latch mounting area of ​​the inner door panel to reduce the risk of punch cracks in that area.

[0006] According to a first aspect, the present application provides a vehicle door assembly, which may include an inner door panel and a door latch mounting portion. The door latch mounting portion may be disposed on the inner door panel, and the inner door panel may have a first mounting surface, and the door latch mounting portion may have a second mounting surface, and the second mounting surface may be connected to the door latch. Furthermore, the first mounting surface is disposed facing the door latch mounting portion, and the second mounting surface is located opposite the first mounting surface. The second mounting surface can be understood to be located between the first mounting surface and the door latch. Furthermore, a first included angle is formed between the first mounting surface and the second mounting surface.

[0007] In this application, the first mounting surface of the inner door panel and the second mounting surface of the door latch mounting portion are arranged at a first included angle, thereby effectively reducing the limitation of the draft angle of the first mounting surface on the connection between the door latch and the door latch mounting portion while still meeting the door latch mounting requirements. Therefore, when the first mounting surface is obtained by stamping and forming, the draft angle of the first mounting surface is large, which helps to reduce the risk of punching cracks on the first mounting surface.

[0008] In the vehicle door assembly provided herein, the draft angle of the first mounting surface may be 5° or more and may be specifically adjusted based on the first included angle between the first mounting surface and the second mounting surface, thereby effectively reducing the stretching rate of the first mounting surface during the stamping process and reducing the risk of punching cracks on the first mounting surface.

[0009] The vehicle door assembly may further include a door latch, which is fixed to the door latch mounting portion. In particular, the door latch is connected to the second mounting surface of the door latch mounting portion. The door latch mounting portion can support the door latch, which can effectively reduce the vibration of the door latch as it rotates with the vehicle door, thereby facilitating the engagement or unlocking process between the door latch and the striker. This helps to improve the durability of the door latch.

[0010] When the door latch is specifically connected to the door latch mounting part, the door latch may have a door latch mounting surface, and the door latch mounting surface may be attached to the second mounting surface of the door latch mounting part, thereby effectively improving the reliability of supporting the door latch by the door latch mounting part.

[0011] In a possible embodiment of the present application, the door latch mounting portion may be fixed to the inner door panel, and the fixing method may be, but is not limited to, welding, riveting, adhesive, etc. The door latch mounting portion may be located between the door latch and the inner door panel, so that the door latch can be connected to the inner door panel via the door latch mounting portion.

[0012] The present application does not limit the method of forming the door latch mounting portion. For example, in a possible embodiment, the door latch mounting portion may be a stamped part. In this case, the door latch mounting portion may have a thin panel structure. Furthermore, to reduce the effect of the arrangement of the door latch mounting portion and the door latch on the draft angle of the first mounting surface, a gap may exist between the door latch mounting portion and the first mounting surface, and the draft angle of the first mounting surface may be adjusted within the range of the gap.

[0013] In another possible embodiment of the present application, the door latch mounting portion may alternatively be a casting obtained using a casting molding process, in which case the door latch mounting portion may have strong structural stability, and therefore the door latch mounting portion may more reliably support the door latch.

[0014] The door latch mounting portion may further include a third mounting surface located between the first and second mounting surfaces and attached to the inner door panel, so that the inner door panel and the door latch mounting portion jointly support the door latch, effectively improving the installation reliability of the door latch.

[0015] In the above-described embodiment, the door latch mounting portion may be an independent structure or may be connected to the inner door panel by welding, riveting, adhesive, or the like. In some other possible embodiments of the present application, the door latch mounting portion and the inner door panel may alternatively be an integrally molded structure. Specifically, the door latch mounting portion and the inner door panel may be processed in a single process. The door latch mounting portion may be a protrusion structure formed on the first mounting surface of the inner door panel. In this way, the structural reliability of the door latch mounting portion and the inner door panel can be improved.

[0016] In any one of the foregoing embodiments of the present application, the thickness of the door latch mounting portion may be 0.7 mm or more so that the door latch mounting portion can stably support the door latch.

[0017] In a possible embodiment of the present application, a notch may be further provided on the inner door panel. Furthermore, there is a connection between the door latch and the second mounting surface, and the notch may be located on the opposite side of the connection, so that the connection can be exposed by the notch and the notch can provide an escape space for tools or connecting pieces used to connect the door latch to the door latch mounting portion, thereby improving the convenience of connecting the door latch to the door latch mounting portion.

[0018] The vehicle door assembly may further include a blocking cover configured to cover the notch, thereby providing waterproof and dustproof properties to the door latch and reducing the impact of the placement of the notch on the aesthetic appearance of the inner door panel.

[0019] In the present application, the method of connecting the isolation cover to the inner door panel is not limited. For example, the connecting method may be a clamp, an adhesive, or the like, so that the connection between the isolation cover and the inner door panel is simple.

[0020] According to a second aspect, the present application further provides a vehicle door, which includes the vehicle door assembly according to the first aspect. In the vehicle door, the installation of the door latch of the vehicle door assembly has little effect on the draft angle of the first mounting surface of the inner door panel. This allows for a larger draft angle of the first mounting surface of the inner door panel, which helps reduce the risk of punching cracks on the first mounting surface of the inner door panel during the stamping process. In this way, the system performance of the vehicle door can be ensured and the processing costs of the vehicle door can be effectively reduced.

[0021] According to a third aspect, the present application further provides a vehicle, the vehicle including a vehicle body and a vehicle door according to the second aspect, the vehicle door being hinged to the vehicle body. The vehicle body may be provided with a striker. When the vehicle door is placed over the vehicle body, the striker can engage with a door latch to lock the vehicle door and the vehicle body. The vehicle provided herein can ensure the system performance of the vehicle door, and the process of unlocking and engaging the door latch of the vehicle door with the striker of the vehicle body is smooth. This effectively improves the durability of the door latch and helps to improve the user experience. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0024] To clarify the objectives, technical solutions, and advantages of the present application, the following describes embodiments of the present application with reference to the accompanying drawings. References to "one embodiment," "some embodiments," and the like in this specification indicate that one or more embodiments of the present application include specific features, structures, or characteristics described with reference to the embodiments. Therefore, descriptions such as "one embodiment," "some embodiments," "some other embodiments," and "other embodiments" appearing in different places in this specification do not necessarily refer to the same embodiments. Instead, these descriptions mean "one or more, but not all, of the embodiments," unless otherwise emphasized. Furthermore, terms such as "first" and "second" in this specification are used merely for distinction and explanation purposes and should not be understood as indicating or implying relative importance or order.

[0025] A vehicle door is an important part of a vehicle. In addition to being used as a passageway for users to enter and exit the vehicle, the vehicle door can also block interference from outside the vehicle and provide a certain level of security for users inside the vehicle. FIG. 1 is a diagram showing a partial structure of a vehicle according to an embodiment of the present application. In the present application, the vehicle may be, but is not limited to, a new energy vehicle, an intelligent vehicle, or another type of vehicle. In addition to the vehicle door 1, the vehicle may further include a vehicle body 2, and the vehicle door 1 may be hinged to the vehicle body 2 via a hinge (not shown in FIG. 1 ). A user can open the vehicle door 1 to get in and out of the vehicle. When the vehicle door 1 is opened, a door latch (not shown in FIG. 1 ) of the vehicle door 1 is unlocked by a striker (not shown in FIG. 1 ) of the vehicle body 2. When the vehicle door 1 is closed, the door latch of the vehicle door 1 engages with the striker of the vehicle body 2, thereby locking the vehicle door 1 and the vehicle body 2. It should be understood that the process of opening and closing the vehicle door 1 is a process in which the vehicle door 1 rotates around the hinge relative to the vehicle body 2.

[0026] A vehicle door 1 may typically include an inner door panel 101 and an outer door panel 102, with the inner door panel 101 being closer to the interior of the vehicle than the outer door panel 102. Currently, the door latch of the vehicle door 1 is often located on the inner door panel 101. However, in order to facilitate the unlocking and engaging of the door latch and striker during the process of opening and closing the vehicle door 1 and improve the user experience, the door latch placement method usually needs to be considered. FIG. 2 is a diagram illustrating the placement requirements of currently commonly used door latches according to an embodiment of the present application, and FIG. 2 shows a three-dimensional image of the door latch engaged with the striker 201. In this three-dimensional image, the X direction indicates the length of the vehicle, i.e., can be understood as the direction from the front of the vehicle to the rear of the vehicle, the Y direction indicates the width of the vehicle, and the Z direction indicates the extension direction of the hinge axis. Note that the directions indicated by the X direction, Y direction, and Z direction in the embodiments of the present application remain unchanged.

[0027] In the process of the vehicle door 1 rotating around the hinge, the door latch may move on a plane defined by the X and Y directions, or on a plane parallel to the plane defined by the X and Y directions. The center at which the door latch 103 engages with the striker 201 may also be located on this plane. In FIG. 2, the dashed line with an arrow indicates the direction in which the door latch 103 engages with the striker 201. Based on this, a line parallel to the hinge axis is formed at the center at which the door latch 103 engages with the striker 201, and the direction in which the door latch 103 engages with the striker 201 is perpendicular to the parallel line of the hinge axis.

[0028] 3 is a projection of the three-dimensional image shown in FIG. 2 onto a plane defined by the X and Y directions. From the connection relationship between the door latch 103 and the inner door panel 101 in the above-described embodiment, it can be seen that the door latch 103 may have a door latch mounting surface 1031. When the door latch 103 engages with the striker 201 shown in FIG. 3, an included angle α exists between the door latch mounting surface 1031 and the Y direction. In a possible embodiment, the included angle α is in the range of 5° to 10°.

[0029] FIG. 4 is a diagram illustrating the structure of a vehicle door assembly according to a conventional solution. When the vehicle door assembly provided by the conventional solution is used with the vehicle door 1 of FIG. 1, FIG. 4 is an AA cross-sectional view of the vehicle door 1 shown in FIG. 1. FIG. 4 illustrates the connection relationship between the door latch 103 and the inner door panel 101 in the conventional solution. To reduce shaking during the unlocking or engaging process of the door latch 103 and the striker 201, in some current solutions, the door latch mounting surface 1031 is essentially parallel to the surface of the door latch mounting area of ​​the inner door panel 101. Furthermore, the door latch 103 may be connected to the inner door panel 101 via a door latch mounting portion 104, and the portion of the door latch mounting portion 104 connected to the door latch 103 is arranged with the same thickness. In this solution, the door latch 103, the door latch mounting portion 104, and the inner door panel 101 may be connected via fasteners such as bolts.

[0030] However, in the inner door panel 101 obtained by stamping, the door latch mounting surface 1031 is basically parallel to the surface of the door latch mounting area of ​​the inner door panel 101, so the draft angle of the surface of the door latch mounting area is approximately 5° to 10°. If the punching depth of the surface of the door latch mounting area in the molding direction of the door latch mounting area is large, if the draft angle is too small, the elongation rate of the area will increase, and as a result, punching cracks will be more likely to occur in the area. Note that the draft angle is usually the angle between the normal direction to the parting surface of the mold and the tangential direction of the side surface where the workpiece intersects with the parting surface of the mold. In this application, the draft angle of the surface of the door latch mounting area of ​​the inner door panel 101 can be understood as the angle between the surface of the door latch mounting area and the Y direction when the vehicle door is in a closed state.

[0031] Based on this, the present application provides a vehicle door assembly, a vehicle door, and a vehicle using the vehicle door. While the inner door panel is still formed by a stamping process and the door latch can still meet the aforementioned placement requirements, the included angle between the door latch mounting surface and the surface of the door latch mounting area of ​​the inner door panel is modified, thereby increasing the draft angle of the surface of the door latch mounting area of ​​the inner door panel. In this way, the risk of punching cracks in the punching area can be reduced without reducing the depth of the inner door panel in the punching direction, thereby reducing the processing cost of the inner door panel. Furthermore, when the vehicle door assembly provided herein is used in a vehicle door, the thickness of the vehicle door can meet the design requirements, thereby reducing the space limitations used to place system function modules such as security modules in the vehicle door and ensuring the system performance of the vehicle door. The present application will be described in more detail below with reference to the accompanying drawings and specific embodiments.

[0032] FIG. 5 illustrates a structure of a vehicle door according to one embodiment of the present application. A vehicle door assembly is disposed on the vehicle door. In this embodiment of the present application, the vehicle door assembly may include an inner door panel 101 and a door latch mounting portion 104. The material of the inner door panel 101 may be, but is not limited to, aluminum, steel, aluminum alloy, or the like. The inner door panel 101 may also be a stamped and formed product. In the embodiment shown in FIG. 5, the vehicle door may further include a vehicle door frame 105, and the inner door panel 101 may be connected to the vehicle door frame 105. In some other possible embodiments of the present application, the inner door panel 101 may alternatively be used in a vehicle door designed without the vehicle door frame 105.

[0033] The door latch mounting portion 104 is disposed on the inner door panel 101, and the material of the door latch mounting portion 104 may be, but is not limited to, aluminum, steel, aluminum alloy, etc. Furthermore, the door latch mounting portion 104 and the inner door panel 101 may be made of the same material or different materials, which is not particularly limited in the present application.

[0034] The door latch mounting portion 104 may be connected to a door latch. In other words, the door latch may be connected to the inner door panel 101 via the door latch mounting portion 104. The present application does not limit the method of connecting the door latch to the door latch mounting portion 104. For example, the door latch may be connected to the door latch mounting portion 104 in a screw manner via a fastener such as a bolt. In some possible embodiments, the door latch may alternatively be fixed to the door latch mounting portion 104 by welding or the like.

[0035] The inner door panel 101 may include a door latch mounting area, and a portion of the door latch mounting portion 104 that is connected to the door latch may be located on the opposite side of the door latch mounting area. In this way, the door latch mounting portion 104 connects the door latch to the inner door panel 101, so that the door latch mounting portion 104 can support the door latch. This effectively increases the structural strength of the door latch mounting area of ​​the inner door panel 101, which helps improve the installation reliability of the door latch.

[0036] For a specific arrangement of the inner door panel 101 and the door latch mounting portion 104, please refer to FIG. 6. FIG. 6 is a cross-sectional view of a vehicle door assembly according to one embodiment of the present application. When the vehicle door assembly provided in this embodiment of the present application is used with the vehicle door 1 of FIG. 1, FIG. 6 is a cross-sectional view of the vehicle door 1 at position AA shown in FIG. 1. In this embodiment of the present application, the inner door panel 101 may include a first mounting surface 1011, which may be a surface of the door latch mounting area. It can be seen from FIG. 6 that in this embodiment of the present application, the first mounting surface 1011 may be arranged facing the door latch mounting portion 104.

[0037] In the embodiment shown in FIG. 6 , the door latch mounting portion 104 may be a stamped and formed product, and the door latch mounting portion 104 has a second mounting surface 1041, which is connected to the door latch 103. The first mounting surface 1011 is disposed facing the door latch mounting portion 104, and the second mounting surface 1041 is located opposite the first mounting surface 1011. Also, with continued reference to FIG. 6 , the vehicle door assembly provided in this embodiment of the present application may further include a door latch 103, and the door latch mounting portion 104 may be located between the inner door panel 101 and the door latch 103. Based on this, it can be seen that the second mounting surface 1041 may be located between the first mounting surface 1011 and the door latch 103. Furthermore, in the present application, a latch mouth via 10111 may be further provided at a position of the inner door panel 101 corresponding to the first mounting surface 1011. The latch opening via 10111 is arranged on the opposite side to the latch opening of the door latch 103, exposing the latch opening of the door latch 103, and a striker on the vehicle body may be inserted into the door latch 103 through the latch opening via 10111.

[0038] FIG. 7a illustrates the structural principle of a vehicle door assembly according to a possible embodiment of the present invention. FIG. 7a illustrates the positional and connection relationships between the inner door panel 101, the door latch mounting portion 104, and the door latch 103 of the vehicle door assembly shown in FIG. 6. From FIG. 7a, it can be seen that in this embodiment of the present invention, the inner door panel 101 can be connected to the door latch mounting portion 104 via a connection point 106, which can be, for example, a welding point or a riveting point. Furthermore, there can be one, two, or more connection points 106. Furthermore, a first included angle β exists between the first mounting surface 1011 of the inner door panel 101 and the second mounting surface 1041 of the door latch mounting portion 104. The first included angle β can be an acute angle, for example, 5° to 8°, 8° to 15°, 15° to 20°, 20° to 25°, or 25° to 45°.

[0039] The door latch 103 may also have a door latch mounting surface 1031. When the door latch 103 is connected to the door latch mounting portion 104, the door latch mounting surface 1031 may be attached to the second mounting surface 1041. This improves the reliability of the door latch mounting portion 104 supporting the door latch 103, reduces vibration of the door latch 103 during the process of opening and closing the vehicle door, and improves the durability of the door latch 103.

[0040] A first included angle β exists between the first mounting surface 1011 and the second mounting surface 1041, and because the second mounting surface 1041 is attached to the door latch mounting surface 1031, a first included angle β also exists between the door latch mounting surface 1031 and the first mounting surface 1011. This reduces the mounting restrictions on the door latch 103 relative to the draft angle of the first mounting surface 1011 obtained by stamping, allowing the draft angle of the first mounting surface 1011 to be increased, thereby reducing the risk of punching cracks in the first mounting surface 1011 of the inner door panel 101 during the stamping process.

[0041] From the above description, it can be seen that the draft angle of the first mounting surface 1011 can be understood as the included angle between the first mounting surface 1011 and the Y direction when the vehicle door is in a closed state. Therefore, in this embodiment of the present application, the draft angle of the first mounting surface 1011 may be 5° or more, for example, 5° to 8°, 8° to 10°, 10° to 13°, 13° to 15°, 15° to 18°, 18° to 22°, 22° to 25°, 25° to 28°, 28° to 30°, 30° to 33°, 33° to 35°, 35° to 38°, 38° to 40°, 40° to 42°, or 42° to 45°. When a striker disposed on a vehicle body is to be engaged with door latch 103, the striker can be inserted into door latch 103 from the side of first mounting surface 1011 that is farther from door latch 103. Therefore, by setting the draw angle of first mounting surface 1011 within a specific range, for example, within a range of 8° to 30°, the engagement requirements between the striker and door latch 103 can be satisfied without setting the length of the striker to be excessively long. This ensures safety in the event of a collision between the striker and door latch 103.

[0042] Please further refer to Figures 6 and 7a. In the embodiment shown in Figures 6 and 7a, the door latch mounting portion 104 may be a stamped and formed product, and the stamped and formed product may have a thin plate structure. In this embodiment of the present application, the thickness of the door latch mounting portion 104 may be 0.7 mm or more so that the door latch mounting portion 104 can stably support the door latch 103. For example, the thickness may be 1 mm, 1.2 mm, 1.5 mm, or 2 mm. The door latch mounting portion 104 may also be fixed to the inner door panel 101 by screw connection, welding, riveting, adhesive bonding, or the like.

[0043] 6 and 7a, when the door latch mounting portion 104 is a sheet metal structure obtained by stamping, a gap 107 may exist between the second mounting surface 1041 of the door latch mounting portion 104 and the first mounting surface 1011 of the inner door panel 101 so that a first included angle β exists between the second mounting surface 1041 of the door latch mounting portion 104 and the first mounting surface 1011 of the inner door panel 101. The size of the gap 107 may be adjusted based on the angle of the first included angle β.

[0044] FIG. 7b also illustrates the structural principle of a vehicle door assembly. The difference between FIG. 7b and FIG. 7a is that FIG. 7b and FIG. 7a are structural principle diagrams corresponding to different cutting positions of the vehicle door assembly. FIG. 7a is a corresponding cross-sectional view of the vehicle door assembly at a latch opening via of the inner door panel 101, and FIG. 7b is a corresponding cross-sectional view of the vehicle door assembly at a portion of the inner door panel 101 where the latch opening via is not located. Please continue to refer to FIG. 7a and FIG. 7b. In this embodiment, since the door latch mounting portion 104 is fixed to the inner door panel 101, a gap 107 may exist between a portion of the door latch mounting portion 104 connected to the door latch 103 and the first mounting surface 1011, and another portion of the door latch mounting portion 104 may be fixed to the inner door panel 101 via a connection point 106. Therefore, when the door latch mounting portion 104 is securely connected to the inner door panel 101, the influence of the portion of the door latch mounting portion 104 that is connected to the door latch 103 on the extraction angle of the first mounting surface 1011 can be further reduced. This helps to increase the extraction angle of the first mounting surface 1011.

[0045] After describing the vehicle door assembly provided in the above-mentioned embodiments of the present application, the following describes the installation procedure of the inner door panel 101, the door latch mounting portion 104, and the door latch 103 in the vehicle door assembly.

[0046] First, the door latch mounting portion 104 can be fixed to the inner door panel 101, and the connection method can be, but is not limited to, screw connection, welding, riveting, or adhesive bonding.

[0047] Next, the door latch 103 can be fixed to the door latch mounting portion 104, and the connection method can be, but is not limited to, a screw connection, welding, or the like.

[0048] Because the second mounting surface 1041 of the door latch mounting portion 104 is located between the first mounting surface 1011 of the inner door panel 101 and the door latch 103, after the door latch mounting portion 104 is fixed to the inner door panel 101 and the door latch 103 is connected to the second mounting surface 1041 of the door latch mounting portion 104, the first mounting surface 1011 may block the connection between the door latch 103 and the door latch mounting portion 104. This makes it inconvenient to realize the connection between the door latch 103 and the door latch mounting portion 104. To solve this problem, refer to FIG. 8. FIG. 8 is an enlarged view of a partial structure at position B in FIG. 1 and may show the area where the first mounting surface 1011 of the inner door panel 101 is located. In this embodiment of the present application, a notch 10112 may be provided in the inner door panel 101, and the notch 10112 penetrates the area where the first mounting surface 1011 is located. The notch 10112 may also be located on the opposite side of the connection between the door latch and the door latch mounting portion 104 .

[0049] The connection portion between the door latch and the door latch mounting portion 104 is a structure used to realize the connection between the door latch and the door latch mounting portion 104. For example, when the door latch is connected to the door latch mounting portion 104 via a fastener such as a bolt, the connection portion is a bolt mounting hole provided in the door latch and the door latch mounting portion 104, and the bolt mounting hole may be a screw hole or a through hole. The first mounting surface 1011 is provided with a notch 10112 on the side opposite to the connection portion, whereby the connection portion is exposed by the notch 10112 and a clearance space for tools and connecting pieces for connecting the door latch to the door latch mounting portion 104 is ensured to realize the connection between the door latch and the door latch mounting portion 104.

[0050] There may be one connection or at least two connection portions between the door latch and the door latch mounting portion 104. Therefore, please refer to FIG. 8 . In the embodiment shown in FIG. 8 , the first mounting surface 1011 may be provided with one notch 10112 for each connection portion. The vehicle door 1 assembly further includes a blocking cover 108, which may be made of, but is not limited to, plastic or rubber. In this way, after the door latch 103 is connected to the door latch mounting portion 104, the blocking cover 108 can cover each notch 10112 one-to-one, thereby ensuring the dustproof and waterproof properties of the door latch 103 and effectively improving the aesthetic appearance of the vehicle door assembly.

[0051] In the present application, the method of connecting the blocking cover 108 to the inner door panel 101 is not limited. For example, the connection method may be a clamp, an adhesive, or the like. The blocking cover 108 may also be detachably connected to the inner door panel 101. This may make it easier to check the connection between the door latch 103 and the door latch mounting portion 104, or to perform maintenance, etc.

[0052] 9 is a diagram showing a partial structure of a vehicle door assembly according to a possible embodiment of the present application. Unlike the embodiment shown in FIG. 8, in the embodiment shown in FIG. 9, one notch 10112 may be provided in the first mounting surface 1011, and the notch 10112 may provide an escape space for all connections. This helps to simplify the structure of the inner door panel 101. In this embodiment of the present application, the blocking cover 108 may further be provided with a through-hole 1081 located on the opposite side of the latch opening via 10111 to facilitate insertion between the striker and the door latch.

[0053] In addition to the arrangement methods provided in the embodiments shown in FIGS. 6, 7a, and 7b, the door latch mounting portion 104 may employ other possible arrangement methods. For example, FIG. 10a illustrates the structural principle of a vehicle door assembly according to another possible embodiment of the present invention. Similar to FIG. 7a, FIG. 10a illustrates a corresponding cross-sectional view of the vehicle door assembly at the latch opening via of the inner door panel 101. In this embodiment, the door latch mounting portion 104 may be a casting processed using a casting molding process, and the material of the casting may be, but is not limited to, aluminum, aluminum alloy, or steel. Due to the high structural strength of the casting, the casting can more reliably support the door latch, improving the installation reliability of the door latch. In this way, the door latch vibration during the opening and closing process of the vehicle door 1 can be reduced, improving the durability of the door latch.

[0054] In the embodiment shown in Fig. 10a, the second mounting surface 1041 of the door latch mounting portion 104 may be arranged with reference to the embodiment shown in Fig. 6 or 7a. For example, the second mounting surface 1041 is connected to the door latch 103, and a first included angle β exists between the second mounting surface 1041 and the first mounting surface 1011 of the inner door panel 101. Also, in the embodiment shown in Fig. 10a, the door latch mounting portion 104 further includes a third mounting surface 1042, which is located between the first mounting surface 1011 and the second mounting surface 1041, and which is attached to the first mounting surface 1011.

[0055] Note that the attachment of the third mounting surface 1042 to the first mounting surface 1011 may mean that the third mounting surface 1042 and the first mounting surface 1011 are in contact with each other by extrusion pressure. In this way, the inner door panel 101 and the door latch mounting portion 104 can jointly support the door latch, thereby making the door latch more securely attached. This helps to improve the service life of the door latch. In some other possible embodiments of the present application, the attachment of the third mounting surface 1042 to the first mounting surface 1011 may alternatively mean that the third mounting surface 1042 and the first mounting surface 1011 are in contact with each other without extrusion pressure.

[0056] A first included angle β exists between the first mounting surface 1011 and the second mounting surface 1041, and because the third mounting surface 1042 is attached to the first mounting surface 1011, a first included angle β also exists between the third mounting surface 1042 and the first mounting surface 1011. In this embodiment of the present application, it may be seen that the door latch mounting portion 104 has a structure of non-uniform thickness. In this case, the thickness of the door latch mounting portion 104 may be understood as the minimum thickness of the door latch mounting portion 104. For example, if the thickness of the door latch mounting portion 104 is 0.7 mm or greater, it may be understood that the minimum thickness of the door latch mounting portion 104 is 0.7 mm or greater.

[0057] FIG. 10b also illustrates the structural principle of a vehicle door assembly. Similar to FIG. 7b, FIG. 10b is a cross-sectional view of a portion of the inner door panel 101 of the vehicle door assembly where no latch vias are disposed. In this embodiment, the shape of the door latch mounting portion 104 is not particularly limited. For example, the door latch mounting portion 104 may have an L-shaped structure. By forming the door latch mounting portion 104 in an L-shaped structure, the entire door latch 103 can be supported, improving the stability of the door latch 103 supported by the door latch mounting portion 104. Furthermore, in addition to the portions where the second mounting surface 1041 and the third mounting surface 1042 are located, another portion of the door latch mounting portion 104 may be fixed to the inner door panel 101. For example, the door latch mounting portion 104 may further include a fourth mounting surface 1043, and the third mounting surface 1042 and the fourth mounting surface 1043 may be connected to form an L-shaped surface, and the fourth mounting surface 1043 may be fixed to the inner door panel 101. The connection method may be, but is not limited to, screw connection, welding, riveting, adhesive bonding, etc. For example, in the embodiment shown in FIG. 10b, the fourth mounting surface 1043 is connected to the inner door panel 101 via a connection point 106, which may be, for example, a welding point or a riveting point. In this way, if the door latch mounting portion 104 is securely connected to the inner door panel 101, the door latch mounting portion 104 and the inner door panel 101 can jointly support the door latch 103, thereby improving the mounting reliability of the door latch 103. This helps to improve the durability of the door latch 103.

[0058] When the door latch mounting portion 104 has the structure shown in FIG. 10a or 10b, please refer to any of the above-mentioned embodiments for the installation procedure of the door latch 103, the door latch mounting portion 104, and the inner door panel 101 of the vehicle door assembly. Details will not be described again here. In addition, the inner door panel 101 of the vehicle door assembly shown in FIG. 10a or 10b may be provided with a notch 10112 that provides an escape space for tools and connecting pieces used to connect the door latch 103 to the door latch mounting portion 104. Please refer to the embodiment shown in FIG. 8 or 9 for a specific arrangement method of the notch 10112. Details will not be described again here.

[0059] In addition to the arrangement method provided in any one of the above-described embodiments, in some possible implementations of the present application, the door latch mounting portion 104 may alternatively be a protrusion structure disposed on the inner door panel 101. For example, FIG. 11 is a diagram illustrating the structural principle of a vehicle door assembly according to another possible embodiment of the present application. In the embodiment shown in FIG. 11, the door latch mounting portion 104 may be an independently formed protrusion structure and may be fixed to the first mounting surface 1011 of the inner door panel 101 by screw connection, welding, riveting, adhesive bonding, or the like. The door latch mounting portion 104 also has a second mounting surface 1041, and a first included angle β exists between the second mounting surface 1041 and the first mounting surface 1011. In the vehicle door assembly provided in the embodiment shown in FIG. 11, except that the door latch mounting portion 104 is different from the vehicle door assemblies provided in the other above-described embodiments, the other structures and the connection relationships between the structures may be set with reference to any of the above-described embodiments. Details will not be described again here.

[0060] As another example, FIG. 12 illustrates the structural principle of a vehicle door assembly according to another possible embodiment of the present application. In this embodiment, the door latch mounting portion 104 and the inner door panel 101 may be integrally molded, and the molding method may be, but is not limited to, stamping or casting. It should be understood that in this embodiment of the present application, the door latch mounting portion 104 is formed on the same plane as the first mounting surface 1011 of the inner door panel 101. Furthermore, the door latch mounting portion 104 also has a second mounting surface 1041, and a first included angle β exists between the second mounting surface 1041 and the first mounting surface 1011. In the vehicle door assembly provided in the embodiment shown in FIG. 12 , except that the door latch mounting portion 104 is different from that of the vehicle door assemblies provided in the other embodiments described above, the other structures and the connection relationships between the structures can be configured with reference to any of the previous embodiments. Details will not be described again here.

[0061] In the present application, the vehicle door may be not only a side door of a vehicle but also a tail door of a vehicle. In the above-described embodiment, the vehicle door assembly is used for a side door. When the vehicle door assembly is used for a tail door, the vehicle door assembly may be specifically referred to as a vehicle door assembly for a side door. For example, FIG. 13 is a diagram showing a partial structure of a tail door portion 1a of a vehicle according to a possible embodiment of the present application.

[0062] The tail door 1a may be connected to the vehicle body 2 via a hinge, and therefore the process of opening and closing the tail door 1a is a process of the tail door 1a rotating around the hinge relative to the vehicle body 2. In the process of the tail door 1a rotating around the hinge, the door latch on the tail door 1a may move on a plane defined by the X direction and the Z direction, or may move on a plane parallel to the plane defined by the X direction and the Z direction. In addition, the center at which the door latch engages with the striker may also be on this plane.

[0063] FIG. 14 is a cross-sectional view taken at position CC in FIG. 13. FIG. 14 may show an arrangement method when the above-described vehicle door assembly is used in a tail door 1a. The arrangement method of the vehicle door assembly in FIG. 14 is similar to the arrangement method of the vehicle door 1 assembly in FIG. 7a. Details will not be described again here. Also, FIG. 14 only shows an arrangement method of the door latch mounting portion 104 in the vehicle door assembly of the tail door 1a. When the door latch mounting portion 104 is arranged in the manner of the other embodiments described above, the door latch mounting portion 104 can still be used in the vehicle door 1 assembly of the tail door 1a. Details will not be described here.

[0064] In the vehicle door assembly provided in this embodiment of the present application, the installation of the door latch 103 has a small effect on the draft angle of the first mounting surface 1011 of the inner door panel 101. This helps to increase the draft angle of the first mounting surface 1011 of the inner door panel 101, and reduce the risk of punching cracks on the first mounting surface 1011 of the inner door panel 101 during the stamping and forming process.

[0065] An embodiment of the present application further provides a vehicle. See FIGS. 1 and 13. The vehicle may include, but is not limited to, a new energy vehicle, an intelligent vehicle, or other types of vehicles. The vehicle may include a vehicle body 2 and a vehicle door 1, and the vehicle door 1 may be hinged to the vehicle body via a hinge. Furthermore, the vehicle door 1 may be divided into side doors or a tail door. For example, there may be four side doors, two left doors and two right doors. There may also be one tail door located at the tail of the vehicle body 2.

[0066] When the vehicle door assembly provided in the embodiment of the present application is used on the vehicle door 1 (side door or tail door) of a vehicle, the process of unlocking and engaging the door latch 103 and the striker 201 with the vehicle body 2 is smooth, which can effectively improve the durability of the door latch 103 and help improve the user experience.

[0067] It is obvious that a person skilled in the art can make various modifications and changes to the present application without departing from the scope of protection of the present application, and the present application intends to cover these modifications and changes of the present application as long as they fall within the scope of protection defined by the following claims and their equivalent technologies.
