Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of vehicles, in particular to a vehicle door and a vehicle. BACKGROUND

[0002] With the development of society and the continuous improvement of living standards, vehicles (such as cars, new energy cars, smart cars, etc.) are used more and more in daily life, and users have higher requirements for the safety of vehicles.

[0003] The vehicle includes a front door and a front fender, the front fender can be located at the position of the front wheel, at least part of the front fender is located above the front wheel, the front fender and the front door are adjacent, the front fender is more adjacent to the front of the vehicle, the front fender and the two edges of the front door are adjacent and spliced, and both are part of the appearance shell of the vehicle. In the scenario of vehicle front collision, under the action of collision impact, the front fender moves backward toward the front door, at least part of the front fender is inserted into the inner side of the front door, the front fender is inserted between the front door and the component (such as the side wall) on the inner side of the front door, and the front door is difficult to open. CONTENT OF THE UTILITY MODEL

[0004] The embodiments of the present application provide a vehicle door and a vehicle, which can block the insertion of a fender and other structural members into the inner side of the door in the scenario of vehicle collision, and avoid the problem that the door is difficult to open.

[0005] The first aspect of the embodiments of the present application provides a vehicle door, which includes a door panel and a blocking structure, the door panel includes opposite inner and outer surfaces. The blocking structure is located on one side edge of the door panel, and the blocking structure protrudes from the inner surface of the door panel. One end of the blocking structure can be fixed with the one side edge of the door panel, and the other end of the blocking structure can protrude and extend inward of the inner surface of the door panel (i.e. inward of the internal space of the vehicle frame).

[0006] The blocking structure is used to abut against the structural member located on one side of the door panel when the structural member moves toward the door panel, so as to block the insertion of the structural member into the inner surface of the door panel (into the side of the internal space of the vehicle frame). For example, in the scenario of vehicle collision, under the action of collision impact, the structural member located on one side of the door panel moves toward the door panel, the protruding blocking structure can abut against the structural member, and the blocking structure can block the insertion of the structural member into the inner surface of the door panel, so as to avoid the insertion of the structural member into the inner side of the door and affect the opening of the door.

[0007] For example, taking the fender as an example, the blocking structure can be located on the edge of the door panel adjacent to the fender, and the blocking structure protrudes from the inner surface of the door panel on that edge. In a collision scenario involving the front of the vehicle, under the impact of the collision, the fender located on the front side of the door panel (i.e., the front fender) moves backward, towards the door panel (i.e., the front door panel). When the fender moves backward to the door position, the protruding blocking structure will abut against the fender, thereby preventing the fender from moving further backward and preventing the fender from inserting into the inner surface of the door panel (the side of the inner surface facing the internal space of the vehicle frame). This prevents structural components such as the fender from inserting between the door and components located on the inner side of the door (such as the side panel). This ensures that structural components such as the fender do not affect the rotation of the door, reducing or avoiding problems such as high door opening force or difficulty in opening the door in scenarios such as vehicle collisions, thus improving the vehicle's safety performance.

[0008] In one possible implementation, the blocking structure includes a first contact surface for abutting against a second contact surface of the structural member. A first end of the first contact surface is connected to the door panel, and a second end of the first contact surface extends obliquely away from the door panel. The first contact surface may be oblique relative to the outer surface of the door panel and may not be perpendicular to the outer surface of the door panel.

[0009] From the first end to the second end of the first contact surface, the first contact surface is inclined towards the structural component, so that the angle between the first contact surface and the outer surface of the door panel can be an obtuse angle. In the event of a vehicle collision, when the second contact surface of a structural component (such as a fender) located on one side of the door panel comes into contact with the inclined first contact surface on the blocking structure, the inclined first contact surface can act as a guide. This allows the structural component (such as the fender) to move along the first contact surface away from the outer surface of the door panel (towards the side facing away from the internal space of the vehicle frame), better ensuring that structural components such as the fender will not insert into the inner surface of the door panel in the event of a vehicle collision, thus preventing difficulties in opening the door.

[0010] In one possible implementation, the angle θ between the first contact surface and the second contact surface ranges from 0° to 10°. Making the first and second contact surfaces nearly parallel enhances the guiding effect of the blocking structure on the movement of structural components (such as fenders) located on one side of the door panel, ensuring that in scenarios such as vehicle collisions, these structural components (such as fenders) can move relative to the door panel away from its outer surface.

[0011] In one possible implementation, the first contact surface is parallel to the second contact surface. Both the first and second contact surfaces can be inclined surfaces. For example, a structural component (such as a fender) located on one side of a car door may include a main body plate, the outer side of which can serve as the external surface of the structural component. The second contact surface can be inclined relative to the outer side of the main body plate, and the angle between the second contact surface and the outer side of the main body plate can be an acute angle. In scenarios such as vehicle collisions, when the second contact surface of the structural component (such as the fender) comes into contact with the first contact surface of the blocking structure, relative sliding is more likely to occur, facilitating the movement of the structural component (such as the fender) away from the outer surface of the door panel.

[0012] In one possible implementation, the included angle α between the first contact surface and the outer surface of the door panel ranges from 90° ≤ α ≤ 150°. Under the condition that the blocking structure can achieve a good blocking effect, it is easy to ensure the gap between the door and structural components located on one side of the door (such as the fender), facilitating production and assembly.

[0013] In one possible implementation, the length of the blocking structure from the end connected to the door panel to the end away from the door panel ranges from 1mm to 50mm. This ensures the blocking structure has a certain protrusion height on the inner side of the door panel, and helps reduce the impact of the blocking structure on the assembly gap between the door and structural components located on one side of the door (such as the fender), making it easy to implement.

[0014] In one possible implementation, the length of the blocking structure from the end connected to the door panel to the end away from the door panel ranges from 3mm to 10mm. This allows the blocking structure to provide effective protection in scenarios such as vehicle collisions, preventing structural components (such as fenders) located on one side of the door from inserting into the inside of the door. It also ensures that the assembly clearance between the door and the structural component is not affected, and has low weight and cost.

[0015] In one possible implementation, the door panel and the blocking structure are integrated into a single unit, formed by integral molding. This allows the blocking structure to have higher strength and stability, improving its ability to prevent structural components (such as fenders) from moving inwards towards the door during vehicle collisions.

[0016] In one possible implementation, the door further includes an outer panel and an inner panel disposed opposite to each other. The outer panel includes a first edge portion and a first main body portion, the first edge portion being located at one side edge of the first main body portion, and the inner panel includes a second edge portion and a second main body portion, the second edge portion and the second main body portion being opposite to the first edge portion and the first main body portion, respectively.

[0017] The first and second edge portions form a blocking structure, while the first and second main body portions form a door panel. The opposite sides of the first and second main body portions respectively form the outer and inner surfaces. In this way, the blocking structure is formed by the inner and outer panels of the door, eliminating the need for additional components to form the blocking structure. This simplifies the door's manufacturing and assembly processes, making it easier to manufacture.

[0018] In one possible implementation, the first edge portion has a edging structure, and at least part of the second edge portion is enclosed within the edging structure. The edging structure eliminates sharp edges on the door, improving its smoothness, aesthetics, and safety. Furthermore, the edging structure enhances the strength and rigidity of the barrier structure formed by the first and second edges, improving its effectiveness in preventing structural components (such as fenders) from moving inwards towards the door during vehicle collisions.

[0019] A second aspect of this application provides a vehicle including a structural member and any of the aforementioned doors, the structural member being located outside one side of the door panel, the structural member being disposed adjacent to the side edge of the door panel having a blocking structure.

[0020] In one possible implementation, the structural components include the front fender, and the doors include the front doors.

[0021] It should be understood that the second aspect of this application corresponds to the technical solution of the first aspect of this application, and the beneficial effects achieved by each aspect and the corresponding feasible implementation are similar, and will not be repeated here.

[0039] The terminology used in the implementation section of this application is for the purpose of explaining specific embodiments of this application only, and is not intended to limit this application.

[0040] This application provides a vehicle that can be an electric vehicle (EV), a pure electric vehicle (PEV / BEV), a hybrid electric vehicle (HEV), a range-extended electric vehicle (REEV), a plug-in hybrid electric vehicle (PHEV), or a new energy vehicle, etc.

[0041] In this embodiment of the application, an automobile is used as an example for illustration.

[0042] Figure 1 This is a partial structural diagram of a vehicle provided in an embodiment of this application.

[0043] For example, see Figure 1 As shown, vehicle 100 may include a frame (not shown) and a door 10. The frame can serve as the main load-bearing structure of vehicle 100, providing the overall strength and rigidity of vehicle 100.

[0044] The door 10 can be mounted on the frame using a hinged connection, allowing the door 10 to rotate relative to the frame, thus enabling the door 10 to open and close. The door 10 allows passengers to enter and exit the interior space of the frame, and also provides safety protection for passengers located inside the interior space of the frame.

[0045] The vehicle 100 may also include a fender 20, which can be mounted on the frame and located above the wheel (not shown in the figure) to prevent mud, stones and other road debris from being thrown up by the wheel, thereby protecting the vehicle 100 and pedestrians.

[0046] The fender 20 and door 10 are positioned adjacent to each other on the vehicle frame, with the fender 20 located to one side of the door 10. Both the fender 20 and door 10 can serve as components of the vehicle's exterior shell. The shapes of their adjacent edges can be matched and spliced ​​together to ensure the overall smoothness and aesthetics of the vehicle 100. A gap must also be maintained between the adjacent edges of the fender 20 and door 10 to ensure aerodynamic performance and the flexibility of opening and closing the door 10.

[0047] For example, taking the direction from the front to the rear of vehicle 100 as the length direction of vehicle 100, as shown in the x-direction in the figure. In some examples, fender 20 may include a front fender 20a and a rear fender (not shown in the figure). The front fender 20a may be located in the front region of vehicle 100 (the area where the front of the vehicle is located), and the front fender 20a is located above the front wheel. The rear fender may be located in the rear region of vehicle 100 (the area where the rear of the vehicle is located), and the rear fender may be located above the rear wheel.

[0048] The vehicle door 10 may include a front door 10a and a rear door (not shown in the figure). The front door 10a may be located in the front area of ​​the vehicle 100, such as... Figure 1 The door 10 shown is the front door 10a, and the fender 20 is the front fender 20a. The front door 10a can be arranged adjacent to the front fender 20a. For example, in the length direction (such as the x direction), the front fender 20a can be located on the front side of the front door 10, and the front fender 20a can be arranged closer to the front of the vehicle.

[0049] The front door 10a can be hinged to the frame on the side adjacent to the front fender 20a, and a handle (not shown in the figure) can be provided on the side of the front door 10a away from the fender 20 to facilitate the opening and closing of the front door 10a by passengers.

[0050] The rear door can be located in the rear area of ​​the vehicle 100. The rear door can be set adjacent to the rear fender. For example, in the length direction (such as the x direction), the rear fender can be located on the side behind the rear door. The rear fender can be set closer to the rear of the vehicle.

[0051] Figure 2 This is a schematic diagram illustrating the positional changes of the front fender and front door in a low-speed forward collision scenario in related technologies.

[0052] It is understandable that when the front of a vehicle is subjected to force, such as in a collision at the front of the vehicle, the front fender will move towards the front door under the impact of the collision. For example, see... Figure 2 As shown in (a), the front fender 201 moves backward in the direction of the arrow shown in the figure, and the front fender 201 moves toward the front door 202.

[0053] like Figure 2 As shown in (b), typically after a collision, a portion of the front fender 201 will insert into the inside of the front door 202 (the side facing the interior space of the vehicle frame), with the portion of the front fender 201 inserted between the front door 202 and a component located inside the front door 202. For example, the vehicle frame may include a side panel (not shown) that can enclose at least a portion of the interior space of the vehicle frame. The side panel may have a front door opening, and the front door 202 may be located on the outside of the side panel (the side facing away from the interior space of the vehicle frame). The side of the front door 202 adjacent to the front fender 201 may be hinged to the side panel, and the front door 202 may cover the front door opening. After a collision in the front area of ​​the vehicle, a portion of the front fender 201 will be inserted between the front door 202 and the side panel.

[0054] As Figure 2 The dashed arrow shown in (b) indicates the direction of movement of the front door 202 when it is subjected to a pulling force. After the collision, if the front door 202 is pulled outward by the handle (not shown in the figure) located on the front door 202, the side of the front door 202 adjacent to the front fender 201 will rotate inward. The front fender 201 inserted inside the front door 202 will obstruct the rotation of the front door 202, resulting in a greater pulling force to open the front door 202. This makes it difficult to open the front door 202, preventing passengers from evacuating from the vehicle in time and creating a safety hazard.

[0055] Based on this, this application provides a vehicle door that includes a door panel and a blocking structure. The blocking structure is located on one side edge of the door panel and protrudes from the inner surface of the door panel. Specifically, one end of the blocking structure can be fixed to one side edge of the door panel, and the other end can protrude inward toward the inner surface of the door panel. In scenarios such as vehicle collisions, under the impact of the collision, structural components located on one side of the door panel will move toward the door. The blocking structure can abut against this structural component, preventing it from inserting into the inner surface of the door panel (the side of the inner surface facing the internal space of the vehicle frame), thus preventing the structural component from inserting into the inside of the door and affecting its opening. Taking a fender as an example, the blocking structure can be located on the edge of the door panel adjacent to the fender, and protrude from the inner surface of the door panel. In scenarios where a collision occurs in the front area of ​​the vehicle, under the impact of the collision, the fender (front fender) moves backward toward the door panel (front door panel). When the fender moves to the door position, the protruding blocking structure will abut against the fender, preventing the fender from moving further back and inserting into the inner surface of the door panel. This ensures that the fender and other structural components will not affect the rotation of the door, reducing or avoiding problems such as high door opening force or difficulty in opening the door in scenarios such as vehicle collisions, thereby improving the vehicle's safety performance.

[0056] In this embodiment of the application, taking the car door as the front door, the assembly relationship between the car door and the front fender and the positional changes in a collision scenario are used as examples to illustrate the structure of the car door.

[0057] Figure 3 for Figure 1 A schematic diagram of the cross-sectional structure of the vehicle along plane AA.

[0058] For example, see Figure 3 As shown, the door 10 may include a door panel 11, which can serve as the main load-bearing component of the door 10, providing the necessary rigidity and strength. For example, the door panel 11 may be mounted on the frame of the vehicle 100 (not shown in the figure), such as on the side panel of the frame.

[0059] The door panel 11 may include an inner surface 11a and an outer surface 11b. The inner surface 11a of the door panel 11 may be the side of the door panel 11 facing the interior space of the vehicle frame, and the side of the inner surface 11a of the door panel 11 facing the interior space of the vehicle frame may be the inner side of the door 10.

[0060] The outer surface 11b of the door panel 11 can be the side of the door panel 11 facing away from the interior space of the vehicle frame, and the outer surface 11b of the door panel 11 can serve as the exterior surface of the door 10.

[0061] The door 10 also includes a blocking structure 12, which is disposed on one side edge of the door panel 11. For example, as...Figure 3 As shown, the door 10 and a structural member 30 of the vehicle 100 are arranged adjacent to each other. For example, the structural member 30 can be a fender 20. The structural member 30 (such as the fender 20) can be located on one side of the door panel 11 (door 10), and the blocking structure 12 can be located on the side edge of the door panel 11 adjacent to the structural member 30 (such as the fender 20). Taking the door 10 as the front door and the fender 20 as the front fender as an example, in the length direction (such as the x direction), the fender 20 can be located in front of the door panel 11 (door 10) (closer to the front of the vehicle), and the blocking structure 12 can be located on the side edge of the door panel 11 adjacent to the fender 20.

[0062] The handle of the door 10 (not shown in the figure) can be located on the side of the door panel 11 away from the blocking structure 12. For example, taking the front door as an example, along the length direction (such as the x direction), the handle and the blocking structure 12 can be located on the two sides of the door panel 11 respectively, and the handle can be provided on the outer surface 11b of the door panel 11.

[0063] The blocking structure 12 can protrude from the inner surface 11a of the door panel 11. The blocking structure 12 can be a structure on the inner surface 11a of the side edge of the door panel 11 adjacent to the fender 20. One end of the blocking structure 12 can be fixed to one side edge of the door panel 11, and the other end of the blocking structure 12 can protrude and extend into the inner surface 11a of the door panel 11 (inside the side of the inner surface 11a facing the internal space of the vehicle frame). That is, the other end of the blocking structure 12 can extend into the internal space of the vehicle frame, so that the blocking structure 12 protrudes and is disposed within the inner surface 11a of the door panel 11.

[0064] For example, taking the thickness direction of the door panel 11 as a direction perpendicular to the inner surface 11a and outer surface 11b of the door panel 11, the distance from the other end face of the blocking structure 12 to the outer surface 11b of the door panel 11 in the thickness direction of the door panel 11 is greater than the distance from the inner surface 11a connected to the blocking structure 12 (such as the inner surface 11a of the door panel 11 near the edge of the fender 20) to the outer surface 11b of the door panel 11. In the thickness direction of the door panel 11, the blocking structure 12 is higher than the inner surface 11a connected to the blocking structure 12.

[0065] In the scenario of a collision involving vehicle 100, the impact of the collision will cause the structural member 30 located on one side of the door panel 11 to move toward the door panel 11. The protruding blocking structure 12 can abut against the structural member 30. The blocking structure 12 can prevent the structural member 30 from being inserted into the inner surface 11a of the door panel 11 (the inner surface 11a facing the side of the vehicle frame interior space), thus preventing the structural member 30 from being inserted into the inside of the door 10 and affecting the opening of the door 10.

[0066] Figure 4 for Figure 3 A diagram illustrating the positional changes of the fenders and doors in a low-speed frontal collision scenario.

[0067] For example, taking the structural component 30 as the fender 20 located on one side of the door 10, see... Figure 4 As shown in (a), the blocking structure 12 is located on the edge of the door panel 11 adjacent to the fender 20, and the blocking structure 12 protrudes from the inner surface 11a of the door panel 11. In scenarios where a collision occurs in the front area of ​​the vehicle 100 (or a frontal collision), such as a low-speed collision in the front area of ​​the vehicle 100, as... Figure 4 As shown in (a), under the impact of a collision, the fender 20 located on the side in front of the door panel 11 moves backward, and the fender 20 moves toward the door panel 11 (door 10) (as along...). Figure 4 (The direction indicated by the dashed arrow in (a)).

[0068] Combination Figure 4 As shown in (b), when the fender 20 moves backward to the position of the door 10 under the impact of a collision, the protruding blocking structure 12 will abut against the fender 20, thereby preventing the fender 20 from moving backward and preventing the fender 20 from inserting into the inner surface 11a of the door panel 11 (the inner surface 11a facing the side of the vehicle frame interior space). This also prevents structural components 30 such as the fender 20 from inserting between the door 10 and the components located inside the door 10 (such as the side panel).

[0069] For example, with Figure 4 The direction of the dashed arrow shown in (b) is a schematic diagram of the movement direction of the door 10 when it is pulled. When the door 10 (door panel 11) is pulled outward by the handle, the side of the door 10 adjacent to the fender 20 and other structural components 30 will rotate inward. The fender 20 and other structural components 30 will not affect the rotation of the door 10, reducing or avoiding the problem of large opening pull or difficulty in opening the door 10 in scenarios such as vehicle collisions, and improving the safety performance of the vehicle 100.

[0070] Figure 4a This is a schematic diagram illustrating a vehicle under low-speed collision test conditions, provided as an embodiment of this application.

[0071] In the embodiments of this application, see Figure 4a As shown, a low-speed collision test (research council for automobile repairs) is used to simulate the opening of the front door after a collision in the front area of ​​the vehicle during driving. Specifically, this is demonstrated in a vehicle 100 with a door 10 having a blocking structure 12 as its front door, as provided in this embodiment, and in a vehicle without a blocking structure (such as...).Figure 2 The vehicle shown (as the front door) underwent a low-speed RCAR crash simulation. In the RCAR crash simulation, a rigid barrier was used as the obstacle, the vehicle's speed was 15 km / h, and 40% of the front width of the vehicle collided with the barrier (40% overlap).

[0072] For vehicles with doors that do not have a blocking structure serving as front doors, the positional changes of the fender (front fender 201) and the door (front door 202) after a simulated collision can be found in the above text. Figure 2 As shown in (b), the fender (front fender 201) inserts into the inside of the door (front door 202), making the door (front door 202) difficult to open. The simulated opening force of the door (front door 202) is approximately 363 N.

[0073] The positional changes of the fender 20 (structural component 30) and the door 10 after a simulated collision in a vehicle 100 with the door 10 having the blocking structure 12 as provided in this embodiment can be seen in [reference needed]. Figure 4 As shown in (b), the blocking structure 12 can abut against the fender 20, and the fender 20 will not insert into the inside of the door 10, thus preventing the door 10 from being difficult to open. The simulated value of the opening force of the door 10 can be approximated as 0N.

[0074] Figure 5 for Figure 3 An enlarged schematic diagram of part A in the middle.

[0075] See in some examples Figure 5 As shown, the blocking structure 12 may include a first contact surface 12a, and the structural member 30 (such as the fender 20) located on one side of the door panel 11 may include a second contact surface 30a. When the structural member 30 moves toward the door panel 11 in a scenario such as a collision of the vehicle 100, the first contact surface 12a of the blocking structure 12 may abut against the second contact surface 30a of the structural member 30 to prevent the structural member 30 from inserting into the inner surface 11a of the door panel 11.

[0076] The first end of the first contact surface 12a can be fixedly connected to the door panel 11. For example, in some examples, the first end of the first contact surface 12a can be in contact with the outer surface 11b of the door panel 11. The second end of the first contact surface 12a can extend away from the door panel 11 and toward the inner surface 11a (inner surface 11a toward the side of the vehicle frame's internal space).

[0077] in, Figure 5The diagram shows an example where the second end of the first contact surface 12a extends inward from the door panel 11 and towards the inner surface 11a, allowing the first contact surface 12a to be inclined relative to the outer surface 11b of the door panel 11. The first contact surface 12a may not be perpendicular to the outer surface 11b of the door panel 11. Furthermore, from the first end of the first contact surface 12a to the second end of the first contact surface 12a, the first contact surface 12a may gradually incline towards the structural member 30 (such as the fender 20) located on one side of the door panel 11, so that the included angle between the first contact surface 12a and the outer surface 11b of the door panel 11 can be an obtuse angle.

[0078] Figure 6 for Figure 5 Another illustration showing the positional changes of the fenders and doors in a low-speed frontal collision scenario.

[0079] Combination Figure 6 As shown, in scenarios such as a collision involving the vehicle 100, when the second contact surface 30a on the structural member 30 (such as the fender 20) located on one side of the door panel 11 comes into contact with the inclined first contact surface 12a on the blocking structure 12, the inclined first contact surface 12a can act as a guide. This allows the structural member 30 (such as the fender 20) to move along the first contact surface 12a toward the outer surface 11b of the door panel 11 (outside the side of the outer surface 11b facing away from the internal space of the frame) (the direction of movement can be referred to by the dotted arrow in the figure). This better ensures that structural members 30 such as the fender 20 will not insert into the inner surface 11a of the door panel 11 in scenarios such as a collision involving the vehicle 100, thus preventing the door 10 from being difficult to open.

[0080] For example, the first contact surface 12a can be a plane, and the second contact surface 30a can also be a plane, so that the first contact surface 12a can play a better guiding role and ensure that structural components 30 such as the fender 20 will not be inserted into the inner surface 11a of the door panel 11.

[0081] In some examples, the angle between the first contact surface 12a and the outer surface 11b of the door panel 11 is defined as α. The range of the angle α between the first contact surface 12a and the outer surface 11b of the door panel 11 can include 90°≤α≤150°. Under the condition that the blocking structure 12 can play a good blocking role, it is easy to ensure the gap between the door 10 and the structural member 30 (such as the fender 20) located on one side of the door 10, which facilitates production and assembly.

[0082] It should be noted that the first contact surface 12a can be perpendicular to the inner surface 11a of the door panel 11. Alternatively, it can be inclined to the inner surface 11a of the door panel 11, and the first contact surface 12a and the inner surface 11a of the door panel 11 can also have an angle that is not 0° or 90°.

[0083] Of course, in some other examples, the first contact surface 12a can also be perpendicular to the outer surface 11b of the door panel 11. In scenarios such as a collision of the vehicle 100, the first contact surface 12a of the blocking structure 12 abuts against the second contact surface 30a on the structural member 30 (such as the fender 20), which can also prevent the structural member 30 from inserting into the inner surface 11a of the door panel 11.

[0084] In some examples, the shape of the first contact surface 12a of the blocking structure 12 can match the shape of the second contact surface 30a of the structural member 30 (such as the fender 20) to facilitate adjacent splicing assembly between the door 10 and the structural member 30 (such as the fender 20). For example, if the first contact surface 12a of the blocking structure 12 is an inclined surface, the second contact surface 30a can also be an inclined surface.

[0085] For example, combining Figure 5 and Figure 6 As shown, taking the fender 20 as an example, the structural component 30 located on one side of the door 10, the structural component 30 may include a main body plate 31. The main body plate 31 can be the main load-bearing component of the structural component 30, providing the required rigidity and strength for the structural component 30 (such as the fender 20). The main body plate 31 can be mounted on the vehicle frame, such as on the side panel of the vehicle frame.

[0086] The main body panel 31 may include opposing inner and outer sides. The inner side of the main body panel 31 may be the side of the main body panel 31 facing the internal space of the vehicle frame. The outer side of the main body panel 31 may be the side of the main body panel 31 facing away from the internal space of the vehicle frame. The outer side of the main body panel 31 may serve as the appearance surface of the structural component 30 (such as the fender 20). The main body panel 31 and the door panel 11 are arranged adjacent to each other, and the outer side of the main body panel 31 and the outer surface 11b of the door panel 11 are spliced ​​together to serve as part of the appearance surface of the vehicle 100.

[0087] The structural component 30 (such as the fender 20) may also include a vertical edge structure 32, which may be located on the side edge of the main body panel 31 adjacent to the door 10. The vertical edge structure 32 may have the aforementioned second contact surface 30a. In scenarios such as a collision of the vehicle 100, the structural component 30 (such as the fender 20) moves toward the door panel 11 (door 10), and the second contact surface 30a of the vertical edge structure 32 abuts against the first contact surface 12a of the blocking structure 12.

[0088] The third end of the second contact surface 30a can be fixedly connected to the main body plate 31. For example, the second contact surface 30a can be connected to the outer side of the main body plate 31.

[0089] The fourth end of the second contact surface 30a may extend inward toward the inner side (i.e., toward the interior space of the frame) away from the main body plate 31, so that the second contact surface 30a may be inclined relative to the outer side of the main body plate 31. In the direction from the third end to the fourth end of the second contact surface 30a, the second contact surface 30a may be inclined in the direction away from the door 10, so that the included angle between the second contact surface 30a and the outer side of the main body plate 31 may be an acute angle.

[0090] This design causes the first contact surface 12a to be inclined relative to the outer surface 11b of the door panel 11, with an obtuse angle between the first contact surface 12a and the outer surface 11b. Conversely, the second contact surface 30a is inclined relative to the outer side of the main body panel 31, with an acute angle between the second contact surface 30a and the outer side. In scenarios such as a vehicle 100 collision, when the inclined second contact surface 30a on the structural component 30 (e.g., fender 20) comes into contact with the inclined first contact surface 12a on the blocking structure 12, relative sliding between the first contact surface 12a and the second contact surface 30a is likely to occur, resulting in a better guiding effect. This ensures that in scenarios such as a vehicle 100 collision, the structural component 30 (e.g., fender 20) can move relative to the door panel 11 away from the outer surface 11b of the door panel 11, preventing the structural component 30, such as the fender 20, from inserting into the inner surface 11a of the door panel 11.

[0091] In some examples, taking the angle θ between the first contact surface 12a and the second contact surface 30a as an example, the range of the angle θ between the first contact surface 12a and the second contact surface 30a can include 0°≤θ≤10°. Making the first contact surface 12a and the second contact surface 30a nearly parallel helps to improve the guiding effect of the blocking structure 12 on the movement of the structural member 30 (such as the fender 20) located on one side of the door panel 11, ensuring that in scenarios such as vehicle collisions, the structural member 30 (such as the fender 20) can move relative to the door panel 11 toward the outer surface 11b of the door panel 11.

[0092] For example, the included angle θ between the first contact surface 12a and the second contact surface 30a can be 0°, that is, the first contact surface 12a and the second contact surface 30a can be parallel. In scenarios such as a collision of the vehicle 100, when the second contact surface 30a of the structural member 30 (such as the fender 20) comes into contact with the first contact surface 12a of the blocking structure 12, it is easier for relative sliding to occur, and it is easier for the structural member 30 (such as the fender 20) to move toward the outer surface 11b of the door panel 11.

[0093] Figure 7 for Figure 5 Enlarged schematic diagram of a portion of the structure of the middle car door.

[0094] In some examples, the length of the blocking structure 12 can range from 1 mm to 50 mm. Specifically, the length of the blocking structure 12 can be the length from the end of the blocking structure 12 that connects to the door panel 11 to the end of the blocking structure 12 that is away from the door panel 11, such as... Figure 7 The length D in the figure is shown.

[0095] The length D of the blocking structure 12 can be within the range of 1mm≤D≤50mm. This ensures that the blocking structure 12 has a certain protrusion height on the inner side of the door panel 11, and helps to reduce the impact of the blocking structure 12 on the assembly gap between the door 10 and the structural component 30 (such as the fender 20) located on one side of the door 10, making it easy to implement.

[0096] In some examples, the length of the blocking structure 12 can range from 3mm to 10mm, so that the blocking structure 12 can play a good blocking effect in scenarios such as vehicle collisions, prevent the structural component 30 (such as the fender 20) located on one side of the door 10 from inserting into the inside of the door 10, and ensure that the assembly gap between the door 10 and the structural component 30 is not affected, while having a small weight and cost.

[0097] See in some examples Figure 7 As shown, the door 10 may include an outer panel 111 and an inner panel 112 disposed opposite to each other, wherein the inner panel 112 may be disposed closer to the interior space of the frame, and the outer panel 111 may be located on the side of the inner panel 112 facing away from the interior space of the frame.

[0098] The outer panel 111 may include a first edge portion 1112 and a first main body portion 1111, with the first edge portion 1112 located at one side edge of the first main body portion 1111. The inner panel 112 may include a second edge portion 1122 and a second main body portion 1121, with the second edge portion 1122 located at one side edge of the second main body portion 1121. The first main body portion 1111 and the second main body portion 1121 may be disposed opposite to each other, and the first edge portion 1112 and the second edge portion 1122 may be disposed opposite to each other.

[0099] The first edge portion 1112 and the first main body portion 1111 may have an angle between them. One end of the first edge portion 1112 may be connected to the first main body portion 1111, and the other end of the first edge portion 1112 may extend away from the first main body portion 1111 and toward the inside of the door 10 (towards the interior space of the vehicle frame).

[0100] The second edge portion 1122 and the second main body portion 1121 may also have an included angle. One end of the second edge portion 1122 may be connected to the second main body portion 1121, and the other end of the second edge portion 1122 may extend away from the second main body portion 1121 and toward the inside of the door 10 (towards the interior space of the vehicle frame). In this way, the first edge portion 1112 and the second edge portion 1122 can be protruding and disposed on the inside of the first main body portion 1111 and the second main body portion 1121 (towards the interior space of the vehicle frame).

[0101] The first edge portion 1112 and the second edge portion 1122 can form a blocking structure 12, and the first main body portion 1111 and the second main body portion 1121 can form a door panel 11. The side of the first main body portion 1111 opposite to the second main body portion 1121 can form the outer surface 11b of the door panel 11, and the side of the second main body portion 1121 opposite to the first main body portion 1111 can form the inner surface 11a of the door panel 11. By using a portion of the inner panel 112 and a portion of the outer panel 111 of the door 10 to form the blocking structure 12, no additional components are needed to form the blocking structure 12, which simplifies the processing, forming, and assembly process of the door 10 and facilitates its manufacturing.

[0102] In some examples, the first edge portion 1112 of the outer panel 111 may have a binding structure 1113. For example, the binding structure 1113 may be present at the end of the first edge portion 1112 away from the first body portion 1111. The binding structure 1113 may form a receiving cavity (not shown in the figure) with the first edge portion 1112. At least a portion of the second edge portion 1122 of the inner panel 112 may be wrapped and received in the receiving cavity formed by the binding structure 1113.

[0103] The edge-wrapping structure 1113 eliminates the sharp edges of the door 10, improving its smoothness, aesthetics, and safety. Furthermore, the edge-wrapping structure 1113 enhances the strength and rigidity of the blocking structure 12 formed by the first edge portion 1112 and the second edge portion 1122, thereby improving the blocking effect of the blocking structure 12 on the inward movement of structural components 30 (such as the fender 20) towards the door 10 in scenarios such as vehicle collisions.

[0104] In some examples, the barrier structure 12 and the door panel 11 can be separate structures, or two relatively independent structures. The barrier structure 12 and the door panel 11 can be molded separately and then assembled and fixed together. This provides greater flexibility in the design of the molding method, structural design, and assembly method of the barrier structure 12 and the door panel 11.

[0105] For example, the blocking structure 12 can be fixed to one side edge of the door panel 11 by means of adhesive connection, welding connection, threaded connection, snap-on connection, etc.

[0106] Alternatively, in some examples, the blocking structure 12 and the door panel 11 can be a single integrated structure, formed by integral molding. This allows the blocking structure 12 to have higher strength and stability, which is beneficial for improving the blocking effect of the blocking structure 12 on the movement of structural components 30 (such as fender 20) toward the inside of the door 10 in scenarios such as vehicle collisions.

[0107] For example, an integral structure with a blocking structure 12 and a door panel 11 can be formed by stamping, thermoforming, roll forming, or other methods.

[0108] For example, taking the aforementioned car door 10 with an outer panel 111 and an inner panel 112 as an example, the inner panel 112 and the outer panel 111 can be assembled together to form a plate-shaped assembly. Using this plate-shaped assembly as a base material, a portion of one edge of the plate-shaped assembly can be bent and protruded beyond the rest by means of stamping or the like, so that the outer panel 111 can be formed with the aforementioned first edge portion 1112 and first main body portion 1111, and the inner panel 112 can be formed with the aforementioned second edge portion 1122 and second main body portion 1121, thereby forming the blocking structure 12 and the door panel 11.
