Description

Technical Field

[0001] This application relates to the field of vehicle technology, and more particularly to a door assembly, a door, and a vehicle. Background Technology

[0002] With economic development and the continuous improvement of living standards, the usage rate of vehicles (new energy vehicles, intelligent vehicles, etc.) is increasing, and users are also placing higher demands on the user experience of vehicles.

[0003] As an important component of a vehicle, the car door provides users with access to and from the vehicle. Users need to open and close the car door when getting in and out of the vehicle. When the door is opened, the door lock on the door unlocks with the latch on the vehicle body; when the door is closed, the door lock on the door engages with the latch on the vehicle body.

[0004] The inner door panel serves not only as a decorative element of the car door but also as a support for the door lock. Typically, to ensure the door lock meets its placement requirements and facilitates smooth unlocking and engagement of the lock and latch, the draft angle of the lock mounting surface, which connects to the inner door panel, is relatively small when the lock is fixed to it. Furthermore, if the lock mounting surface is fitted flush against the surface of the lock mounting area of ​​the inner door panel, the draft angle of that area will also be small. When the stamping depth along the forming direction of the lock mounting area of ​​the inner door panel is large, an excessively small draft angle can easily lead to stamping cracks during the stamping process. Summary of the Invention

[0005] This application provides a door assembly, a door, and a vehicle, which increases the draft angle of the door lock mounting area of ​​the inner door panel, thereby reducing the risk of stamping cracking in that area.

[0006] In a first aspect, this application provides a vehicle door assembly, which may include an inner door panel and a door lock mounting portion. The door lock mounting portion may be disposed on the inner door panel, which may have a first mounting surface, and the door lock mounting portion may have a second mounting surface, which can be used to connect a door lock. Furthermore, the first mounting surface faces the door lock mounting portion, and the second mounting surface faces away from the first mounting surface, which can be understood as the second mounting surface being located between the first mounting surface and the door lock. Additionally, a first angle is formed between the first mounting surface and the second mounting surface.

[0007] In this application, by setting the first mounting surface of the inner door panel and the second mounting surface of the door lock mounting part at a first included angle, the installation requirements of the door lock can be met while effectively reducing the draft angle of the connection between the door lock and the door lock mounting part on the first mounting surface. This allows for a larger draft angle of the first mounting surface during stamping, which helps reduce the risk of stamping cracking of the first mounting surface.

[0008] Using the door assembly provided in this application, the draft angle of the first mounting surface can be greater than or equal to 5°, which can be adjusted according to the first included angle between the first mounting surface and the second mounting surface. This can effectively reduce the draw ratio of the first mounting surface during the stamping process, thereby reducing the risk of stamping cracks in the first mounting surface.

[0009] In addition, the door assembly may also include a door lock, which is fixedly connected to a door lock mounting portion. Specifically, the door lock is connected to a second mounting surface of the door lock mounting portion. The door lock mounting portion can support the door lock, thereby effectively reducing the door lock's wobble during door rotation, making the engagement or unlocking process of the door lock and the latch smoother, which helps improve the door lock's durability.

[0010] When connecting the door lock to the door lock mounting part, the door lock can have a door lock mounting surface that can fit against the second mounting surface of the door lock mounting part. This effectively improves the reliability of the door lock mounting part's support for the door lock.

[0011] In one possible implementation of this application, the door lock mounting part can be fixed to the inner door panel, and the fixing method can be, but is not limited to, welding, riveting, or gluing. The door lock mounting part can be located between the door lock and the inner door panel, thereby enabling the door lock to be connected to the inner door panel through the door lock mounting part.

[0012] In this application, the formation method of the door lock mounting part is not limited. For example, in one possible implementation, the door lock mounting part may be a stamped part, in which case the door lock mounting part may be a thin plate structure. In addition, in order to reduce the influence of the door lock mounting part and the door lock on the draft angle of the first mounting surface, a gap may be made between the door lock mounting part and the first mounting surface, so that the draft angle of the first mounting surface can be adjusted within the range of the gap.

[0013] In another possible implementation of this application, the door lock mounting part can also be a casting obtained through a casting process. This can give the door lock mounting part stronger structural stability, thereby enabling it to provide more reliable support for the door lock.

[0014] The door lock mounting part may also include a third mounting surface, which is located between the first mounting surface and the second mounting surface, and the third mounting surface is in contact with the inner door panel. Then, the inner door panel and the door lock mounting part can jointly support the door lock, thereby effectively improving the installation reliability of the door lock.

[0015] In the above implementation, the door lock mounting part can be an independent structure, which can be connected to the inner door panel by welding, riveting, or bonding. In other possible implementations of this application, the door lock mounting part can also be an integrally formed structure with the inner door panel, that is, the door lock mounting part and the inner door panel are processed together in one step. The door lock mounting part can be a protruding structure formed on the first mounting surface of the inner door panel. This can help improve the structural reliability of the door lock mounting part and the inner door panel.

[0016] In any of the above implementations of this application, the thickness of the door lock mounting part can be greater than or equal to 0.7 mm, thereby enabling the door lock mounting part to provide stable support for the door lock.

[0017] In one possible implementation of this application, the inner door panel may also have a notch. Additionally, a connecting portion is provided between the door lock and the second mounting surface, and the notch can be positioned opposite the connecting portion, thereby exposing the connecting portion and providing clearance for tools or connectors used to connect the door lock and the door lock mounting portion, thus improving the ease of connection between the door lock and the door lock mounting portion.

[0018] In addition, the door assembly may also include a plug that can be used to seal the aforementioned gap, which can not only waterproof and dustproof the door lock, but also reduce the impact of the gap on the appearance of the inner door panel.

[0019] In this application, the connection method between the cover and the inner door panel is not limited. Examples of such connection methods include snap-fit ​​or adhesive bonding, which makes the connection between the cover and the inner door panel simpler.

[0020] Secondly, this application also provides a vehicle door, which includes the door assembly of the first aspect. In this vehicle door, the installation of the door lock of the door assembly has a relatively small impact on the draft angle of the first mounting surface of the inner door panel, which is conducive to increasing the draft angle of the first mounting surface of the inner door panel, thereby reducing the risk of stamping cracking of the first mounting surface of the inner door panel during the stamping process. This can effectively control the processing cost of the vehicle door while ensuring the system performance of the vehicle door.

[0021] Thirdly, this application also provides a vehicle, which may include a body and a door, the door being hinged to the body. The body may be equipped with a latch, which engages with a door lock when the door is mounted on the body, thereby locking the door to the body. In the vehicle provided by this application, the system performance of the door is guaranteed, and the unlocking and engagement process between the door lock and the latch on the body is relatively smooth, effectively improving the durability of the door lock and enhancing the user experience.

[0043] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in detail below with reference to the accompanying drawings. References to "one embodiment" or "some embodiments" in this specification mean that one or more embodiments of this application include a specific feature, structure, or characteristic described in connection with that embodiment. Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. Furthermore, the terms "first," "second," etc., used in this specification are used only for distinguishing purposes and should not be construed as indicating or implying relative importance, nor as indicating or implying order.

[0044] Car doors are an important component of a vehicle. Besides serving as a passageway for users to enter and exit, they also act as a barrier against external interference and, to a certain extent, provide safety for the occupants. (Refer to...) Figure 1 , Figure 1 This is a partial structural diagram of a vehicle provided in an embodiment of this application. In this application, the vehicle may be, but is not limited to, a new energy vehicle, an intelligent vehicle, or other similar type of vehicle. In addition to the door 1, the vehicle may also include a body 2, and the door 1 and the body 2 can be connected by a hinge (…). Figure 1 (Not shown in the image) Hinged. Users can get in and out of the vehicle by opening door 1. When door 1 is open, the door lock on door 1 ( Figure 1 (not shown in the image) and the latch on vehicle body 2 ( Figure 1The door unlocks between the door (not shown in the diagram). When door 1 is closed, the door lock on door 1 engages with the latch on the body 2, thus locking door 1 to the body 2. It can be understood that the process of opening or closing door 1 is the process of door 1 rotating relative to the body 2 around its hinge.

[0045] A vehicle door 1 typically includes an inner door panel 101 and an outer door panel 102, with the inner door panel 101 positioned closer to the interior of the vehicle than the outer door panel 102. Currently, door locks on the vehicle door 1 are mostly located on the inner door panel 101. To ensure a smooth unlocking and engagement process between the door lock and the latch during the opening and closing of the vehicle door 1, thus improving the user experience, the arrangement of the door lock usually needs to be considered. (Refer to...) Figure 2 , Figure 2 This is a schematic diagram illustrating the arrangement requirements of a commonly used door lock, provided as an embodiment of this application. Figure 2 The diagram shown is a three-dimensional representation of the door lock and latch 201 in engagement. In this diagram, the X-direction indicates the length of the vehicle, which can also be understood as the direction from the front to the rear; the Y-direction indicates the width of the vehicle; and the Z-direction indicates the direction of the hinge axis. It is worth noting that the X, Y, and Z directions appearing in various embodiments of this application indicate the same direction.

[0046] During the rotation of the door 1 around the hinge, the door lock can move within a plane defined by the X and Y directions, or within a plane parallel to the plane defined by the X and Y directions. Furthermore, the center of engagement between the door lock 103 and the latch 201 can also be located within this plane. Figure 2 The direction of engagement between the door lock 103 and the latch 201 is indicated by a dashed line with an arrow. Based on this, a line parallel to the hinge axis can be drawn at the center of engagement between the door lock 103 and the latch 201. In this case, the direction of engagement between the door lock 103 and the latch 201 is perpendicular to the line parallel to the hinge axis.

[0047] Additionally, refer to Figure 3 , Figure 3 What is shown is Figure 2 The three-dimensional diagram shown is a projection view in the plane defined by the X and Y directions. From the above embodiment regarding the connection relationship between the door lock 103 and the inner door panel 101, it can be seen that the door lock 103 can have a door lock mounting surface 1031. Figure 3 When the door lock 103 is engaged with the latch 201, there is an angle α between the door lock mounting surface 1031 and the Y direction. In one possible embodiment, the angle α is 5° to 10°.

[0048] Reference Figure 4 , Figure 4 This is a structural diagram of a door assembly provided for a conventional solution. When... Figure 1 When the door 1 in the middle uses the door components provided by this conventional solution, Figure 4 for Figure 1 The diagram shows a cross-sectional view of door 1 (AA section). Figure 4 The connection between the door lock 103 and the inner door panel 101 in this conventional solution is illustrated. To reduce wobbling during the unlocking or engagement of the door lock 103 and the latch 201, some current solutions maintain the door lock mounting surface 1031 substantially parallel to the surface of the door lock mounting area of ​​the inner door panel 101. Alternatively, the door lock 103 can be connected to the inner door panel 101 via a door lock mounting portion 104, where the portion of the door lock mounting portion 104 used for connecting the door lock 103 is of equal thickness. In this solution, the door lock 103, the door lock mounting portion 104, and the inner door panel 101 can be connected using fasteners such as bolts.

[0049] In the door inner panel 101 obtained by stamping, the door lock mounting surface 1031 is basically parallel to the surface of the door lock mounting area of ​​the door inner panel 101, which makes the draft angle of the surface of the door lock mounting area approximately 5° to 10°. When the stamping depth of the surface of the door lock mounting area along its forming direction is large, an excessively small draft angle will result in a large draw ratio in this area, making it prone to stamping cracks. It is worth mentioning that the draft angle usually refers to the angle between the tangential direction of the side where the workpiece intersects the parting surface of the mold and the normal direction of the parting surface of the mold. In this application, the draft angle of the surface of the door lock mounting area of ​​the door inner panel 101 can be understood as the angle between the surface of the door lock mounting area and the Y direction when the door is in the closed state.

[0050] Based on this, this application provides a door assembly, a door, and a vehicle using the door. By changing the angle between the door lock mounting surface and the surface of the door lock mounting area of ​​the door panel, while still using a stamping process to form the inner door panel and ensuring the door lock still meets the above-mentioned arrangement requirements, the draft angle of the door lock mounting area of ​​the inner door panel can be increased. This reduces the risk of stamping cracking in this area without reducing the depth of the inner door panel along its stamping direction, and also lowers the processing cost of the inner door panel. Furthermore, when the door assembly provided in this application is applied to a door, the door thickness can meet design requirements, thereby reducing the space constraints on the door for installing system functional modules such as safety modules, thus ensuring the system performance of the door. The application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0051] Reference Figure 5 , Figure 5This is a schematic diagram of a vehicle door provided in one embodiment of this application. The vehicle door is equipped with a door assembly. In this embodiment of the application, the door assembly may include an inner door panel 101 and a door lock mounting portion 104. The inner door panel 101 may be made of, but is not limited to, aluminum, steel, or aluminum alloy, and may be a stamped part. Figure 5 In the illustrated embodiment, the door may further include a door frame 105, and the inner door panel 101 may be connected to the door frame 105. In some other possible embodiments of this application, the inner door panel 101 may also be applied to a door design without a door frame 105.

[0052] The door lock mounting part 104 is disposed on the inner door panel 101. The material of the door lock mounting part 104 may be, but is not limited to, aluminum, steel, or aluminum alloy. In addition, the material of the door lock mounting part 104 and the inner door panel 101 may be the same or different, and no specific limitation is made thereto in this application.

[0053] The door lock mounting part 104 can be used to connect the door lock, that is, the door lock can be connected to the inner door panel 101 through the door lock mounting part 104. In this application, the connection method between the door lock and the door lock mounting part 104 is not limited. Exemplarily, it can be connected by threaded fasteners such as bolts. In some possible embodiments, the door lock and the door lock mounting part 104 can also be fixedly connected by welding or other methods.

[0054] The inner door panel 101 may include a door lock mounting area, and the portion of the door lock mounting part 104 for connecting the door lock may be disposed opposite to this door lock mounting area. In this way, by connecting the door lock to the inner door panel 101 through the door lock mounting part 104, the door lock mounting part 104 can provide support for the door lock, which can effectively increase the structural strength of the door lock mounting area of ​​the inner door panel 101 and improve the reliability of the door lock installation.

[0055] When specifically configuring the inner door panel 101 and the door lock mounting part 104, refer to Figure 6 , Figure 6 This is a cross-sectional view of a door assembly provided in one embodiment of this application. Figure 1 When the door 1 in the present application uses the door assembly provided in this embodiment, Figure 6 for Figure 1 The image shows a cross-sectional view of the door 1 at point AA. In this embodiment of the application, the inner door panel 101 may include a first mounting surface 1011, which may be a surface of the aforementioned door lock mounting area. Figure 6 As can be seen, in this embodiment of the application, the first mounting surface 1011 may be disposed toward the door lock mounting portion 104.

[0056] exist Figure 6In the illustrated embodiment, the door lock mounting portion 104 can be a stamped part, having a second mounting surface 1041 for connection with the door lock 103. A first mounting surface 1011 faces the door lock mounting portion 104, and the second mounting surface 1041 faces away from the first mounting surface 1011. Further details can be found by referring to… Figure 6 The door assembly provided in this embodiment of the application may further include a door lock 103, and the door lock mounting part 104 may be located between the inner door panel 101 and the door lock 103. Based on this, it can be understood that the second mounting surface 1041 may be located between the first mounting surface 1011 and the door lock 103. In addition, in this application, a lock slot through hole 10111 may be provided at the position of the inner door panel 101 corresponding to the first mounting surface 1011. The lock slot through hole 10111 may be arranged opposite to the lock slot of the door lock 103 to expose the lock slot of the door lock 103, so that the latch on the vehicle body can be inserted into the door lock 103 through the lock slot through hole 10111.

[0057] Reference Figure 7a , Figure 7a This is a schematic diagram of the structural principle of a door assembly provided in one possible embodiment of the present application. Figure 7a Can be used for display Figure 6 The diagram illustrates the positional and connection relationships between the inner door panel 101, the door lock mounting portion 104, and the door lock 103 of the door assembly. Figure 7a As can be seen, in this embodiment of the application, the inner door panel 101 and the door lock mounting part 104 can be connected by a connection point 106, which can be a weld point or a rivet point. Furthermore, there can be one, two, or more connection points 106. Additionally, 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 lock mounting part 104. This first included angle β can be an acute angle, and can be, for example, 5°–8°, 8°–15°, 15°–20°, 20°–25°, or 25°–45°.

[0058] In addition, the door lock 103 may have a door lock mounting surface 1031. When the door lock 103 is connected to the door lock mounting part 104, the door lock mounting surface 1031 may fit against the second mounting surface 1041. This helps to improve the support reliability of the door lock mounting part 104 for the door lock 103, thereby reducing the shaking of the door lock 103 during the opening and closing of the vehicle door, and improving the durability of the door lock 103.

[0059] Since there is a first included angle β between the first mounting surface 1011 and the second mounting surface 1041, and the second mounting surface 1041 is in contact with the door lock mounting surface 1031, there is also a first included angle β between the door lock mounting surface 1031 and the first mounting surface 1011. This helps to reduce the restriction of the door lock 103's installation on the draft angle of the first mounting surface 1011 formed by stamping, thereby facilitating the increase of the draft angle of the first mounting surface 1011, and reducing the risk of stamping cracking of the first mounting surface 1011 of the inner door panel 101 during the stamping process.

[0060] As can be seen from the above, the draft angle of the first mounting surface 1011 can be understood as the angle between the first mounting surface 1011 and the Y direction when the door is in the closed state. Therefore, in this embodiment of the application, the draft angle of the first mounting surface 1011 can be greater than or equal to 5°, and can be, for example, 5°~8°, 8°~10°, 10°~13°, 13°~15°, 15°~18°, 18°~22°, 22°~25°, 25°~28°, 28°~30°, 30°~33°, 33°~35°, 35°~38°, 38°~40°, 40°~42°, or 42°~45°. Since the latch on the vehicle body can be inserted into the door lock 103 from the side of the first mounting surface 1011 opposite to the door lock 103 when engaged with the door lock 103, the latch can be inserted into the door lock 103. When the draft angle of the first mounting surface 1011 is set within a certain range, such as 8° to 30°, the length of the latch does not need to be set too long to meet the engagement requirements between the latch and the door lock 103, which is beneficial to the safety of the latch colliding with the door lock 103.

[0061] You can continue to refer to Figure 6 and Figure 7a ,exist Figure 6 and Figure 7a In the illustrated embodiment, the door lock mounting portion 104 can be a stamped part, which can be a thin plate structure. In this embodiment of the application, in order to enable the door lock mounting portion 104 to provide stable support for the door lock 103, the thickness of the door lock mounting portion 104 can be greater than or equal to 0.7 mm, such as 1 mm, 1.2 mm, 1.5 mm, or 2 mm. In addition, the door lock mounting portion 104 can be fixed to the inner door panel 101 by means of, but not limited to, threaded connection, welding, riveting, or bonding.

[0062] From the above text Figure 6 and Figure 7aIn the description of the door assembly shown, when the door lock mounting part 104 is a stamped thin plate structure, in order to make a first included angle β between the second mounting surface 1041 of the door lock mounting part 104 and the first mounting surface 1011 of the inner door panel 101, a gap 107 can be made between the door lock mounting part 104 and the first mounting surface 1011. The size of the gap 107 can be adjusted according to the angle of the first included angle β.

[0063] Additionally, you can refer to Figure 7b , Figure 7b It also shows a schematic diagram illustrating the structural principle of the door assembly. Among them, Figure 7b and Figure 7a The difference lies in the fact that the two are structural principle diagrams corresponding to different cut positions of the door assembly. Figure 7a The cross-sectional view of the corresponding door assembly at the lock hole in the inner door panel 101, and Figure 7b This is a cross-sectional view of the portion of the door assembly on the inner door panel 101 where the lock slot is not located. Please refer to... Figure 7a and Figure 7b Since the door lock mounting part 104 is fixedly connected to the inner door panel 101, in this embodiment, the portion of the door lock mounting part 104 used to connect the door lock 103 can have the aforementioned gap 107 with the first mounting surface 1011, while the other portions of the door lock mounting part 104 can be fixedly connected to the inner door panel 101 through the connection point 106. This allows for a reliable connection between the door lock mounting part 104 and the inner door panel 101, while also reducing the impact of the portion of the door lock mounting part 104 used to connect the door lock 103 on the draft angle of the first mounting surface 1011, which is beneficial for increasing the draft angle of the first mounting surface 1011.

[0064] After introducing the door assembly provided in the above embodiments of this application, the installation steps of the door inner panel 101, door lock mounting part 104 and door lock 103 in the door assembly will be described next.

[0065] First, the door lock mounting part 104 can be fixedly connected to the inner door panel 101. The connection method can be, but is not limited to, threaded connection, welding, riveting or bonding.

[0066] Secondly, the door lock 103 can be fixedly connected to the door lock mounting part 104, and the connection method can be, but is not limited to, threaded connection or welding.

[0067] Since the second mounting surface 1041 of the door lock mounting part 104 is located between the first mounting surface 1011 of the inner door panel 101 and the door lock 103, after fixing the door lock mounting part 104 to the inner door panel 101, and then connecting the door lock 103 to the second mounting surface 1041 of the door lock mounting part 104, the first mounting surface 1011 will block the connection between the door lock 103 and the door lock mounting part 104, making it inconvenient to connect the door lock 103 and the door lock mounting part 104. To solve this problem, refer to... Figure 8 , Figure 8 for Figure 1 The enlarged view of a portion of the structure at point B shows the area where the first mounting surface 1011 of the inner door panel 101 is located. In this embodiment of the application, the inner door panel 101 may have a notch 10112 that penetrates the area where the first mounting surface 1011 is located. Furthermore, the notch 10112 may be positioned opposite to the connection between the door lock and the door lock mounting portion 104.

[0068] The connection between the door lock and the door lock mounting part 104 refers to the structure used to connect the two. For example, when the door lock and the door lock mounting part 104 are connected by fasteners such as bolts, the connection is a bolt mounting hole opened on the door lock and the door lock mounting part 104. The bolt mounting hole can be a threaded hole or a through hole. By opening a notch 10112 on the first mounting surface 1011 opposite to the connection, the notch 10112 exposes the connection, thereby providing clearance space for tools and connectors used to connect the door lock and the door lock mounting part 104, so as to facilitate the connection between the door lock and the door lock mounting part 104.

[0069] There can be one connecting part or at least two connecting parts between the door lock and the door lock mounting part 104. (See also...) Figure 8 ,exist Figure 8 In the illustrated embodiment, a notch 10112 can be formed on the first mounting surface 1011 corresponding to each connecting part. Additionally, the door assembly 1 may also include a cover 108, which may be made of, but is not limited to, plastic or rubber. Thus, after the connection between the door lock 103 and the door lock mounting part 104 is completed, the cover 108 can seal each notch 10112 accordingly, thereby providing dust and water protection for the door lock 103 while also effectively improving the aesthetic appearance of the door assembly.

[0070] In this application, the connection method between the plug 108 and the inner door panel 101 is not limited; exemplary methods include snap-fitting or adhesive bonding. Alternatively, the plug 108 and the inner door panel 101 can be detachably connected, which facilitates inspection or maintenance of the connection between the door lock 103 and the door lock mounting part 104.

[0071] Additionally, you can refer to Figure 9 , Figure 9 This is a partial structural diagram of a door assembly provided for one possible embodiment of this application. (Compared to the above...) Figure 8 The embodiment shown differs from the one described above in that... Figure 9 In the illustrated embodiment, the first mounting surface 1011 may have a notch 10112, which provides clearance space for all connecting parts, thus simplifying the structure of the inner door panel 101. It is worth noting that in this embodiment of the application, the cover 108 may also have a through hole 1081 opposite to the lock opening 10111, thereby facilitating the insertion of the latch and the door lock.

[0072] In this application, the door lock mounting part 104 can adopt the above-mentioned... Figure 6 , Figure 7a and Figure 7b Besides the configuration provided in the illustrated embodiment, other possible configuration methods can also be used. For example, see [link to example]. Figure 10a , Figure 10a This is a schematic diagram illustrating the structural principle of a door assembly provided for another possible embodiment of this application. Figure 7a Similarly, Figure 10a This corresponds to the cross-sectional view of the door assembly at the lock through-hole in the inner door panel 101. In this embodiment, the door lock mounting part 104 can be a casting produced by a casting process. The material of the casting can be, but is not limited to, aluminum, aluminum alloy, or steel. Due to the high structural strength of the casting, it can provide more reliable support for the door lock, thereby improving the reliability of the door lock installation. This reduces the shaking of the door lock during the opening and closing of the door 1, thus improving the durability of the door lock.

[0073] exist Figure 10a In the embodiment shown, the second mounting surface 1041 of the door lock mounting portion 104 can be referred to as described above. Figure 6 or Figure 7a The illustrated embodiment is configured such that, for example, the second mounting surface 1041 is used to connect the door lock 103, and a first included angle β is formed between the second mounting surface 1041 and the first mounting surface 1011 of the inner door panel 101. Additionally, in Figure 10a In the illustrated embodiment, the door lock 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 the third mounting surface 1042 is in contact with the first mounting surface 1011.

[0074] It is worth mentioning that the third mounting surface 1042 and the first mounting surface 1011 can be in contact with each other and have a pressing force. This allows the inner door panel 101 and the door lock mounting part 104 to jointly support the door lock, thereby making the installation of the door lock more reliable and improving its service life. In some other possible embodiments of this application, the third mounting surface 1042 and the first mounting surface 1011 can also be in contact without a pressing force.

[0075] Since there is a first included angle β between the first mounting surface 1011 and the second mounting surface 1041, and the third mounting surface 1042 is in contact with the first mounting surface 1011, there is also a first included angle β between the third mounting surface 1042 and the first mounting surface 1011. Therefore, in this embodiment of the application, the door lock mounting portion 104 is a non-uniform thickness structure. In this case, the thickness of the door lock mounting portion 104 can be understood as its minimum thickness. For example, if the thickness of the door lock mounting portion 104 is greater than or equal to 0.7 mm, it can be understood that the minimum thickness of the door lock mounting portion 104 is greater than or equal to 0.7 mm.

[0076] Additionally, you can refer to Figure 10b , Figure 10b It also shows a schematic diagram illustrating the structural principle of the door assembly. Figure 7b Similarly, Figure 10b This corresponds to the cross-sectional view of the portion of the door assembly in the inner door panel 101 without a lock slot. In this embodiment, the shape of the door lock mounting portion 104 is not specifically limited; it can be exemplary in an L-shape. This L-shaped door lock mounting portion 104 can support the entire door lock 103, thereby improving the stability of the door lock mounting portion 104 in supporting the door lock 103. Furthermore, apart from the portion containing the second mounting surface 1041 and the third mounting surface 1042, other portions of the door lock mounting portion 104 can be fixedly connected to the inner door panel 101. For example, the door lock mounting portion 104 can also include a fourth mounting surface 1043, where the third mounting surface 1042 and the fourth mounting surface 1043 are connected to form an L-shaped surface. The fourth mounting surface 1043 can be fixedly connected to the inner door panel 101, and the connection method can be, but is not limited to, threaded connection, welding, riveting, or bonding. For example, in Figure 10b In the illustrated embodiment, the fourth mounting surface 1043 is connected to the inner door panel 101 via a connection point 106, which may be, for example, a weld point or a rivet point. This allows for a reliable connection between the door lock mounting part 104 and the inner door panel 101, while simultaneously enabling both the door lock mounting part 104 and the inner door panel 101 to jointly support the door lock 103, thereby improving the reliability of the door lock 103 installation and ultimately enhancing its durability.

[0077] When the door lock mounting part 104 adopts Figure 10a or Figure 10bWhen the structure shown is used, the installation steps of the door lock 103, door lock mounting part 104, and inner door panel 101 of the door assembly can be referred to any of the above embodiments, and will not be repeated here. Furthermore, Figure 10a or Figure 10b The inner door panel 101 of the door assembly shown may also be provided with a notch 10112 to provide clearance for tools and connectors used to connect the door lock 103 and the door lock mounting part 104. The specific arrangement of the notch 10112 can be found in [reference needed]. Figure 8 or Figure 9 The embodiments shown are not described in detail here.

[0078] In this application, in addition to the arrangement provided in any of the above embodiments, the door lock mounting part 104 may also be a protruding structure provided on the inner door panel 101 in some possible embodiments. For example, see reference to Figure 11 , Figure 11 A schematic diagram illustrating the structural principle of a door assembly provided for another possible embodiment of this application. Figure 11 In the illustrated embodiment, the door lock mounting portion 104 can be an independently formed protruding structure, which can be fixed to the first mounting surface 1011 of the inner door panel 101 by means of, but not limited to, threaded connection, welding, riveting, or bonding. Additionally, the door lock 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. Figure 11 In the door assembly provided in the illustrated embodiment, except for the door lock mounting part 104 which differs from the door assembly provided in the other embodiments, the other structures and the connection relationships between the structures can be set with reference to any of the above embodiments, and will not be described in detail here.

[0079] For example, you can refer to Figure 12 , Figure 12 This is a schematic diagram illustrating the structural principle of a car door assembly provided for another possible embodiment of this application. In this embodiment, the door lock mounting portion 104 can be integrally formed with the inner door panel 101, and its forming method can be, but is not limited to, stamping or casting. It is understood that in this embodiment of the application, the door lock mounting portion 104 is formed on the plane containing the first mounting surface 1011 of the inner door panel 101. Additionally, the door lock mounting portion 104 also has a second mounting surface 1041, which has a first included angle β with the first mounting surface 1011. Figure 12 In the door assembly provided in the illustrated embodiment, except for the door lock mounting part 104 which differs from the door assembly provided in the other embodiments, the other structures and the connection relationships between the structures can be set with reference to any of the above embodiments, and will not be described in detail here.

[0080] It is worth noting that in this application, "vehicle door" refers not only to the side doors of a vehicle but also to the tailgate. In the above embodiments, the description uses the application of the door assembly to a side door as an example. When the door assembly is applied to the tailgate, its specific configuration can be referenced to that of the side door. For example, refer to... Figure 13 , Figure 13 A partial structural schematic diagram of the tailgate 1a portion of a vehicle provided in one possible embodiment of this application is shown.

[0081] Since the tailgate 1a is also connected to the vehicle body 2 via a hinge, the opening and closing process of the tailgate 1a is the process of the tailgate 1a rotating relative to the vehicle body 2 around the hinge. It can be understood that during the rotation of the tailgate 1a around the hinge, the door lock on the tailgate 1a can move within a plane defined by the X and Z directions, or within a plane parallel to the plane defined by the X and Z directions. Furthermore, the center of engagement between the door lock and the latch can also be located within this plane.

[0082] Reference Figure 14 , Figure 14 for Figure 13 Sectional view at point CC. Figure 14 This can be used to demonstrate the arrangement of the aforementioned door assembly when applied to the tailgate 1a, wherein, Figure 14 The way the door components are set up and Figure 7a The setup of the door 1 component is similar, and will not be elaborated upon here. Additionally, Figure 14 Only one configuration of the door lock mounting part 104 in the door assembly of the tailgate 1a is shown. When the door lock mounting part 104 adopts the configuration of other embodiments described above, it can still be used in the door assembly of the tailgate 1a, and will not be described in detail here.

[0083] In the door assembly provided in this application embodiment, the installation of the door lock 103 has little impact on the draft angle of the first mounting surface 1011 of the inner door panel 101. This is beneficial to increasing the draft angle of the first mounting surface 1011 of the inner door panel 101, thereby reducing the risk of stamping cracking of the first mounting surface 1011 of the inner door panel 101 during the stamping process.

[0084] This application also provides a vehicle, which can be referred to in the embodiments. Figure 1 and Figure 13 The vehicle includes, but is not limited to, new energy vehicles, intelligent vehicles, and other types of vehicles. The vehicle may include a body 2 and doors 1, which are hinged to the body. In addition, the doors 1 may be side doors or tail doors. For example, there may be four side doors, namely two left-side doors and two right-side doors; there may be one tail door, located at the rear of the body 2.

[0085] When the door assembly provided in the above embodiments of this application is applied to the door 1 (side door or tail door) of a vehicle, the unlocking and engagement process between the door lock 103 and the latch 201 on the vehicle body 2 can be smoother, which can effectively improve the durability of the door lock 103 and improve the user experience.

[0086] Obviously, those skilled in the art can make various modifications and variations to this application without departing from the scope of protection of this application. Therefore, if such modifications and variations fall within the scope of the claims of this application and their equivalents, this application also intends to include such modifications and variations.
