Description

Technical Field

[0001] This utility model relates to the field of automotive structural technology, specifically to a car door structure. Background Technology

[0002] Window regulators are used to adjust the up and down movement of car windows at the door. Regulators are usually fixed to the inside of the door and control the up and down movement of the window glass with the help of sliding rails.

[0003] In related technologies, window regulators often use dual sliding rails to control the raising and lowering of car windows. However, when the dual sliding rails are installed on the car door, there is often a large error in their position, which affects the smoothness of the window raising and lowering and is prone to jamming or abnormal noise. In addition, the sliding rails have poor fixed stability on the car door and are prone to displacement when subjected to road bumps and vibrations caused by vehicle driving for a long time, which in turn affects the raising and lowering of the window. Utility Model Content

[0004] The purpose of this utility model is to provide a car door structure to solve the problems in the prior art where the position of the double slide rails of the window regulator often has a large error and the slide rails have poor fixing stability on the car door, which affects the window lifting.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A vehicle door structure includes: an inner door panel, including a base plate and a bottom frame disposed on one side of the base plate along the z-direction; a bracket, having at least two positioning portions thereon; the at least two positioning portions are spaced apart along the x-direction; a lifter having at least two slide rails, the at least two slide rails respectively cooperating with and connected to the at least two positioning portions; the bracket further includes a support plate, the support plate being recessed to form a recess, the support plate being fixed to the bottom frame, and the recess being disposed facing the bottom frame.

[0007] Based on the aforementioned technical means, by setting up a bracket with a support plate and at least two positioning parts, the bracket has at least two positioning parts spaced apart along the x-direction. At least two slide rails are respectively positioned in conjunction with the two positioning parts, thereby reducing installation errors. The two slide rails of the lifter are installed at the same bracket, reducing the length of the dimensional chain, thus greatly reducing the positional error of the slide rails after the lifter is installed. In addition, the support plate stably fixes the bottom frame of the inner door panel. The bottom frame has better support and load-bearing performance than the base plate. At the same time, the support plate has a recess facing the bottom frame to avoid interference between the bracket and the bottom frame. The cross-sectional shape of the support plate with the recess is approximately L-shaped or U-shaped, further improving the structural strength of the support plate and the fixing stability of the bracket on the inner door panel. This effectively improves the fixing stability of the slide rails on the door, prevents slide rail deviation, and ensures the accuracy and strength of the window glass in the installation position, as well as the smoothness of the window glass during lifting.

[0008] Furthermore, the support plate includes a first sub-plate and a second sub-plate, which are connected at a predetermined angle to form the recess between the first sub-plate and the second sub-plate; at least a portion of the first sub-plate and / or the second sub-plate is attached to and fixed to the bottom frame.

[0009] Based on the above technical means, by setting a first sub-plate and a second sub-plate, and the first sub-plate and the second sub-plate are L-shaped, a three-dimensional support structure is formed, so that a triangular force system is formed between the first sub-plate, the second sub-plate and the bottom frame, which can effectively resist external forces and ensure good structural stability when subjected to road bumps and vibrations caused by vehicle driving for a long time.

[0010] Furthermore, the bracket also includes a connecting plate, which is connected to the side of the first sub-plate away from the second sub-plate and extends along the z-direction away from the second sub-plate; the connecting plate is fixed to the base plate, and the positioning part is disposed at the connecting plate; wherein, at least two connecting plates are provided and are spaced apart along the x-direction, and at least two positioning parts are respectively disposed at at least two connecting plates; and / or, at least two positioning parts are spaced apart at the same connecting plate.

[0011] According to the above technical means, by setting a connecting plate, one side of which is connected to the support plate, the plate body of the connecting plate extends along the z-direction towards the side closer to the car window glass, which plays a role in compensating for the distance difference between the support plate and the installation position of the lifter slide rail. The positioning part is set at the connecting plate to ensure smooth cooperation between the positioning part and the lifter slide rail.

[0012] Furthermore, the positioning part is a notch, which is formed on the edge of the connecting plate away from the first sub-plate; the notch is a strip-shaped opening, and the extension direction of the notch is parallel to the extension direction of the slide rail.

[0013] Based on the above technical means, by setting a strip-shaped notch as a positioning part, and the extension direction of the notch is consistent with the extension direction of the slide rail, the slide rail gradually penetrates and engages inside the notch, and only needs to move in a single direction to play a guiding role. No additional angle adjustment is required, making the installation process convenient. Furthermore, since the extension directions of the two are consistent, no lateral force will be generated on the slide rail, avoiding slide rail deviation and improving the positional accuracy of the slide rail.

[0014] Furthermore, the connecting plate includes a main board and a flange disposed on at least one side of the main board along the x direction, and the positioning portion is formed on the main board; at least a portion of the flange is attached to and fixed to the substrate, and the main board and the flange are connected at a predetermined angle to form a first cavity between the main board and the substrate.

[0015] Based on the above technical means, by setting the flange, the support plate and part of the base plate are combined to form an integral structure with a cavity. For example, hollow steel pipe has a stronger bending resistance than solid steel bar. The bending and torque resistance of the integral structure with a cavity is greatly enhanced, which can effectively enhance the connection strength between the connecting plate and the base plate, improve the local stiffness and strength of the bracket and the inner panel of the door, and improve the installation stability of the lifter and the window glass.

[0016] Furthermore, the bottom frame includes a first side plate and a second side plate connected at a predetermined angle; at least a portion of the first sub-plate and the first side plate overlap in the z-direction, and at least a portion of the second sub-plate and the second side plate overlap in the y-direction.

[0017] According to the above technical means, by setting a first side plate and a second side plate, the projection of the first sub-plate on the first side plate at least partially overlaps with the first side plate to form a longitudinal anti-collision structure, and the projection of the second sub-plate on the second side plate at least partially overlaps with the second side plate to form a lateral anti-collision structure. When the vehicle is subjected to lateral and longitudinal forces during driving, the support plate and the bottom frame can jointly resist deformation, effectively ensuring the shape and structural stability of the support plate and the bottom frame, ensuring the installation accuracy of the regulator, window glass and other components such as sealing strips in the inner panel of the door, ensuring smooth window glass lifting and lowering, and maintaining good door sealing.

[0018] Furthermore, at least one edge of the first sub-plate and / or the second sub-plate extends toward the side near the bottom frame to form a connecting portion; the connecting portion is attached to and fixed to the bottom frame to form a second cavity between the bottom frame and the support plate.

[0019] According to the above-mentioned technical means, by setting a second cavity, the connection strength between the support plate and the bottom frame can be effectively enhanced, the local rigidity and strength of the bracket and the inner panel of the door can be improved, and the installation stability of the regulator and the window glass can be improved.

[0020] Furthermore, the door structure also includes a crash beam, which is fixed to the inner panel of the door and located on the side of the bracket away from the inner panel of the door; the crash beam and at least one of the connecting plates are at least partially overlapped in the y-direction.

[0021] According to the above-mentioned technical means, by setting up a crash beam, the crash beam can disperse the lateral force on the door; the crash beam and at least one connecting plate are at least partially overlapped in the y direction to form a lateral crash protection structure, which can protect the occupants inside.

[0022] Furthermore, the door structure also includes a sill beam, which is located on the side of the inner door panel away from the bracket, and the sill beam and the bottom frame overlap at least partially in the y-direction.

[0023] Based on the aforementioned technical means, the upper part of the bracket overlaps with the anti-collision beam in the y-direction, and the lower part overlaps with the bottom frame and sill beam in the y-direction. The bracket, anti-collision beam, inner door panel, and sill beam together form a large-area lateral anti-collision structure. Thus, when the vehicle is subjected to lateral forces during driving, the anti-collision beam, inner door panel, bracket, and sill beam can jointly resist deformation, effectively ensuring the shape and structural stability of the support plate and inner door panel, and protecting the occupants from injury during a collision.

[0024] Furthermore, the first sub-plate and the second sub-plate are respectively provided with multiple ribs, and the multiple ribs are respectively arranged along the x-direction or the y-direction.

[0025] According to the above-mentioned technical means, multiple ribs extend along the x and y directions and are respectively set on the surface of the first sub-plate and the second sub-plate away from the inner panel of the door, so as to further improve the structural strength of the support plate.

[0026] The beneficial effects of this utility model are:

[0027] (1) This utility model reduces installation errors by setting up a bracket with a support plate and at least two positioning parts. The at least two positioning parts are spaced apart along the x-direction, and at least two slide rails are respectively positioned in cooperation with the two positioning parts. The two slide rails of the lifter are installed at the same bracket, reducing the length of the dimension chain, thereby greatly reducing the position error of the slide rails after the lifter is installed. In addition, the support plate stably fixes the bottom frame of the inner panel of the car door. The bottom frame has better support and load-bearing performance than the base plate. At the same time, the support plate has a recess facing the bottom frame to avoid interference between the bracket and the bottom frame. The cross-sectional shape of the support plate with the recess is approximately L-shaped or U-shaped, which further improves the structural strength of the support plate and the fixing stability of the bracket on the inner panel of the car door, thereby effectively improving the fixing stability of the slide rails on the car door, avoiding slide rail deviation, ensuring the accuracy and strength of the car window glass in the installation position, and the smoothness of the car window glass when it is raised and lowered.

[0028] (2) By setting a first sub-plate and a second sub-plate, and the first sub-plate and the second sub-plate are L-shaped, a three-dimensional support structure is formed, so that a triangular force system is formed between the first sub-plate, the second sub-plate and the bottom frame, which can effectively resist external forces and ensure good structural stability when subjected to road bumps and vibrations caused by vehicle driving for a long time.

[0029] (3) By setting a connecting plate, and connecting one side of the connecting plate is connected to the support plate, the plate body of the connecting plate extends along the z direction towards the side closer to the car window glass, which plays the role of compensating for the distance difference between the support plate and the installation position of the lifter slide rail. The positioning part is set at the connecting plate to ensure smooth cooperation between the positioning part and the lifter slide rail.

[0030] (4) This utility model sets a strip-shaped notch as a positioning part, and the extension direction of the notch is consistent with the extension direction of the slide rail. As the slide rail gradually penetrates and is engaged inside the notch, it only needs to move in a single direction to play a guiding role. No additional angle adjustment is required, making the installation process convenient. Furthermore, since the extension directions of the two are consistent, no lateral force will be generated on the slide rail, avoiding slide rail deviation and improving the positional accuracy of the slide rail.

[0031] (5) By setting the flange, the support plate and part of the base plate are combined to form an integral structure with a cavity. For example, hollow steel pipe has stronger bending resistance than solid steel bar. The bending and torque resistance of the integral structure with cavity is greatly enhanced, which can effectively enhance the connection strength between the connecting plate and the base plate, improve the local stiffness and strength of the bracket and the inner panel of the car door, and improve the installation stability of the lifter and the car window glass.

[0032] (6) By setting a first side plate and a second side plate, the projection of the first sub-plate on the first side plate at least partially overlaps with the first side plate to form a longitudinal anti-collision structure. The projection of the second sub-plate on the second side plate at least partially overlaps with the second side plate to form a lateral anti-collision structure. When the vehicle is subjected to lateral and longitudinal forces during driving, the support plate and the bottom frame can resist deformation together, effectively ensuring the shape and structural stability of the support plate and the bottom frame, ensuring the installation accuracy of the lifter, window glass and other components such as sealing strips in the inner panel of the door, ensuring smooth lifting of the window glass, and maintaining good sealing of the door.

[0033] (7) By setting a second cavity, this utility model can effectively enhance the connection strength between the support plate and the bottom frame, improve the local rigidity and strength of the bracket and the inner panel of the car door, and improve the installation stability of the lifter and the car window glass.

[0034] (8) By setting up an anti-collision beam, the anti-collision beam plays the role of dispersing the lateral force on the car door; the anti-collision beam and at least one connecting plate are at least partially overlapped in the y direction to form a lateral anti-collision structure, which plays the role of protecting the occupants inside.

[0035] (9) The upper part of the bracket of this utility model overlaps with the anti-collision beam in the y-direction and the lower part overlaps with the bottom frame and sill beam in the y-direction. The bracket, anti-collision beam, inner door panel and sill beam form a large-area lateral anti-collision structure. When the vehicle is subjected to lateral force during driving, the anti-collision beam, inner door panel, bracket and sill beam can resist deformation together, effectively ensuring the stability of the shape and structure of the support plate and inner door panel, and protecting the occupants from injury during collision.

[0036] (10) In this utility model, multiple reinforcing bars extend along the x and y directions respectively and are disposed on the surface of the first sub-plate and the second sub-plate away from the inner panel of the car door, so as to further improve the structural strength of the support plate.

Detailed Implementation

[0051] The embodiments of this utility model will be described below with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be understood that the preferred embodiments are only for illustrating this utility model and not for limiting the scope of protection of this utility model.

[0052] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0053] This embodiment proposes a door structure, such as Figures 1 to 13 As shown, it includes: a door inner panel 1, the door inner panel 1 includes a base plate 11 and a bottom frame 12 disposed on one side of the base plate 11 along the z direction; a bracket 2, which is provided with at least two positioning parts 21; the at least two positioning parts 21 are spaced apart along the x direction; a lifter 3, which has at least two slide rails 31, the at least two slide rails 31 are respectively connected to the at least two positioning parts 21 and fixed to the door inner panel 1; the bracket 2 also includes a support plate 22, the support plate 22 is recessed to form a recess 23, the support plate 22 is fixed to the bottom frame 12, and the recess 23 is disposed facing the bottom frame 12.

[0054] It should be noted that the window glass is located on the side of the inner door panel 1 away from the bottom frame 12. In this embodiment, the window glass can be, but is not limited to, frameless window glass. Frameless window glass is a type of window where the upper part of the door does not have a frame and the glass is directly exposed to the outside of the vehicle body. Compared with ordinary window glass, frameless window glass does not have the assistance of a frame when it is raised and lowered, so the requirements for positional accuracy and smoothness of raising and lowering are higher.

[0055] In this embodiment, the lifter 3 has two slide rails 31. During installation, the two slide rails 31 are respectively positioned in conjunction with two positioning parts 21. The positioning parts 21 constrain the position of the slide rails 31, thereby reducing the positional error of the slide rails 31. At the same time, the slide rails 31 cooperate with the positioning parts 21 at the bracket 2, so that the two slide rails 31 of the lifter 3 are installed at the same bracket 2, reducing the accumulation of production (stamping, welding) errors caused by being distributed on two or more parts. From a production perspective, the length of the dimensional chain is shortened to a large extent, thereby greatly reducing the positional error of the slide rails 31 after the lifter 3 is installed, thereby improving the installation accuracy of the car window glass and the stability of the car window glass when it is raised and lowered.

[0056] In this embodiment, the support plate 22 stably fixes the bottom frame 12 of the inner door panel 1. The bottom frame 12 has better support and load-bearing performance than the base plate 11. At the same time, the support plate 22 is provided with a recess 23 to avoid interference between the bracket 2 and the bottom frame 12. The cross-sectional shape of the support plate 22 with the recess 23 is approximately L-shaped, which further improves the structural strength of the support plate 22 and the fixing stability of the bracket 2 at the inner door panel 1. Under the constraint of the positioning part 21, it effectively prevents the bracket 2 and the slide rail 31 that cooperates with the bracket 2 from shifting when affected by road bumps and vibrations caused by vehicle driving for a long time. This ensures the accuracy and strength of the window glass in the installation position and the smoothness of the window glass when it is raised and lowered.

[0057] In this embodiment, by setting a bracket 2, which has a support plate 22 and at least two positioning parts 21, and the at least two positioning parts 21 are spaced apart along the x-direction, on the one hand, at least two slide rails 31 are respectively positioned in cooperation with the two positioning parts 21, thereby reducing installation errors. On the other hand, the two slide rails 31 of the lifter 3 are all installed at the same bracket 2, reducing the length of the dimension chain, thereby greatly reducing the positional error of the slide rails 31 after the lifter 3 is installed. In addition, the support plate 22 stably fixes the bottom frame 12 of the inner panel 1 of the car door. The bottom frame 12 has better support and load-bearing performance than the base plate 11. At the same time, the support plate 22 is provided with a recess 23, which is set towards the bottom frame 12 to avoid interference between the bracket 2 and the bottom frame 12. The cross-sectional shape of the support plate 22 with the recess 23 is approximately L-shaped or U-shaped, which further improves the structural strength of the support plate 22 and the fixing stability of the bracket 2 on the inner panel 1 of the car door, thereby effectively preventing the slide rails 31 from shifting, ensuring the accuracy and strength of the window glass in the installation position, and the smoothness of the window glass when it is raised and lowered.

[0058] In this embodiment, as Figures 2 to 4 As shown, the support plate 22 includes a first sub-plate 221 and a second sub-plate 222. The first sub-plate 221 and the second sub-plate 222 are connected at a predetermined angle to form a recess 23 between the first sub-plate 221 and the second sub-plate 222. At least a portion of the first sub-plate 221 and / or the second sub-plate 222 is attached to and fixed to the bottom frame 12.

[0059] In this embodiment, the support plate 22 may be, but is not limited to, a first sub-plate 221 and a second sub-plate 222 connected at a predetermined angle, and a recess 23 is formed between the first sub-plate 221 and the second sub-plate 222; wherein, the first sub-plate 221 and the second sub-plate 222 are L-shaped to form a three-dimensional support structure, and one or both of the first sub-plate 221 and the second sub-plate 222 are fixed to the bottom frame 12 to form a triangular force-bearing system between the first sub-plate 221, the second sub-plate 222 and the bottom frame 12, which can effectively resist external forces and ensure good structural stability when subjected to road bumps and vibrations caused by vehicle driving for a long time.

[0060] In this embodiment, as Figures 2 to 4 As shown, the bracket 2 also includes a connecting plate 24, which is connected to the side of the first sub-plate 221 away from the second sub-plate 222 and extends along the z-direction away from the second sub-plate 222; the connecting plate 24 is fixed to the base plate 11, and the positioning part 21 is provided at the connecting plate 24; wherein, at least two connecting plates 24 are provided and are spaced apart along the x-direction, and at least two positioning parts 21 are respectively provided at at least two connecting plates 24; and / or, at least two positioning parts 21 are spaced apart at the same connecting plate 24.

[0061] In this embodiment, one side of the connecting plate 24 is connected to the support plate 22, and the plate body of the connecting plate 24 extends along the z-direction towards the side closer to the window glass, which serves to compensate for the distance difference between the support plate 22 and the installation position of the lifter 3 slide rail 31. The positioning part 21 is set at the connecting plate 24 to ensure smooth cooperation between the positioning part 21 and the lifter 3 slide rail 31. At the same time, the specific arrangement of the positioning part 21 on the connecting plate 24 is not limited. A single positioning part 21 or multiple spaced positioning parts 21 can be set at a single connecting plate 24. The single or multiple connecting plates 24 are spaced along the x-direction. The specific arrangement can be determined according to different production conditions to improve the compatibility of the door structure.

[0062] In this embodiment, as Figure 2 and Figure 8 As shown, the positioning part 21 is a notch, which is formed on the side edge of the connecting plate 24 away from the first sub-plate 221; the notch is a strip-shaped opening, and the extension direction of the notch is parallel to the extension direction of the slide rail 31.

[0063] In this embodiment, the strip-shaped notch can be, but is not limited to, U-shaped. The extension direction of the notch is parallel to the plane formed by the x and z directions, and the extension direction is at a certain angle relative to the z direction, so that the extension direction of the notch is consistent with the extension direction of the slide rail 31. The slide rail 31 is provided with a protruding mounting part 32. The mounting part 32 is an existing component and can be, but is not limited to, a bolt fixed to the slide rail 31. The mounting part 32 engages with the notch, thereby constraining and limiting the slide rail 31. When the mounting part 32 engages with the notch, it first engages at the opening of the notch. Since the extension direction of the notch is consistent with the extension direction of the slide rail 31, the mounting part 32 gradually moves into the notch and engages in the process. It only needs to move in a single direction, which plays a guiding role. No additional angle adjustment is required, making the installation process convenient. Furthermore, since the extension directions of the two are consistent, no lateral force is generated on the slide rail 31, avoiding the slide rail 31 from shifting and improving the positional accuracy of the slide rail 31.

[0064] In this embodiment, as Figures 2 to 4 As shown, the connecting plate 24 includes a main plate 241 and a flange 242 disposed on at least one side of the main plate 241 along the x direction. A positioning part 21 is formed on the main plate 241. At least a portion of the flange 242 is attached to and fixed to the substrate 11. The main plate 241 and the flange 242 are connected at a predetermined angle to form a first cavity 25 between the main plate 241 and the substrate 11.

[0065] In this embodiment, the main board 241 has flanges 242 on both sides along the x-direction. The flanges 242 are connected to the main board 241 at a preset angle. When the bracket 2 is engaged with the inner door panel 1, the connecting plate 24 is positioned opposite to the base plate 11. The main board 241 is positioned away from the base plate 11 relative to the flanges 242. Thus, the flanges 242 are attached to and fixed to the base plate 11. The fixing method can be, but is not limited to, welding. A certain gap is left between the main board 241 and the base plate 11 to form a first cavity 25 between the main board 241 and the base plate 11. This allows the support plate and part of the base plate 11 to form an integral structure with a cavity. For example, hollow steel pipes have stronger bending resistance than solid steel bars. The bending and torque resistance of the integral structure with a cavity is greatly enhanced. This can effectively enhance the connection strength between the connecting plate 24 and the base plate 11, improve the local stiffness and strength of the bracket 2 and the inner door panel 1, and improve the installation stability of the lifter 3 and the window glass.

[0066] In this embodiment, as Figure 6 and Figure 7 As shown, the bottom frame 12 includes a first side plate 121 and a second side plate 122 connected at a predetermined angle; the first sub-plate 221 and the first side plate 121 are at least partially overlapped in the z-direction, and the second sub-plate 222 and the second side plate 122 are at least partially overlapped in the y-direction.

[0067] In this embodiment, the projection of the first sub-plate 221 onto the first side plate 121 is at least partially overlapped with the first side plate 121, so that the first sub-plate 221 and the second sub-plate 222 are structurally matched to form a longitudinal anti-collision structure along the z-direction. The projection of the second sub-plate 222 onto the second side plate 122 is at least partially overlapped with the second side plate 122, so that the second sub-plate 222 and the second side plate 122 are matched to form a lateral anti-collision structure along the y-direction. When the vehicle is subjected to lateral and longitudinal forces during driving, the support plate 22 and the bottom frame 12 can jointly resist deformation, effectively ensuring the shape and structural stability of the support plate 22 and the bottom frame 12, ensuring the installation accuracy of the lifter 3, the window glass and other components such as the sealing strip at the inner panel of the door, ensuring smooth lifting of the window glass, and maintaining good sealing of the door.

[0068] In this embodiment, as Figures 2 to 4 As shown, at least one edge of the first sub-plate 221 and / or the second sub-plate 222 extends toward the side near the bottom frame 12 to form a connecting portion 29; the connecting portion 29 is attached to and fixed to the bottom frame 12 to form a second cavity 26 between the bottom frame 12 and the support plate 22.

[0069] In this embodiment, portions of the plate located at the opposite edges of the second sub-plate 222 along the x-direction extend toward the side closer to the bottom frame 12 to form a connecting portion 29. The plate at the connecting portion 29 protrudes toward the side closer to the second side plate 122 relative to other plates of the second sub-plate 222 located beside the connecting portion 29. The connecting portion 29 is fixed to the second side plate 122, and the fixing method can be, but is not limited to, welding. The connecting portion 29 supports the second sub-plate 222 at a certain height relative to the second side plate 122, so that the second... A certain gap is left between the side plate 122 and the second sub-plate 222. At the same time, in this embodiment, the first sub-plate 221 is not connected to the first side plate 121. The first sub-plate 221 and the first side plate 121 are spaced apart, thereby forming a second cavity 26 between the bottom frame 12 and the support plate 22. The second cavity 26 communicates with the first cavity 25, which can effectively enhance the connection strength between the support plate 22 and the bottom frame 12, improve the local rigidity and strength of the bracket 2 and the inner panel 1 of the door, and improve the installation stability of the lifter 3 and the window glass.

[0070] It is worth noting that, in order to improve the fixing stability of the support plate 22 and the bottom frame, multiple connecting parts 29 can be provided on the side of the second sub-plate 222 away from the first sub-plate 221, so that the second sub-plate 222 is fully and firmly fixed to the bottom frame.

[0071] In this embodiment, as Figures 11 to 13 As shown, the door structure also includes a crash beam 4, which is fixed to the inner door panel 1 and located on the side of the bracket 2 away from the inner door panel 1; the crash beam 4 and at least one connecting plate 24 are at least partially overlapped in the y direction.

[0072] In this embodiment, one end of the anti-collision beam 4 is fixed to one side of the inner door panel 1 along the x-direction, and the other end is fixed to the other side of the inner door panel 1 along the x-direction. At the same time, it is inclined towards the side closer to the window glass, so that the anti-collision beam 4 is at a certain angle relative to the x-direction, which plays the role of dispersing the lateral force on the door.

[0073] In this embodiment, as Figures 11 to 13 As shown, the door structure also includes a sill beam 5, which is located on the side of the inner door panel 1 away from the bracket 2, and the sill beam 5 and the bottom frame 12 overlap at least partially in the y-direction.

[0074] In this embodiment, on one hand, in the upper half of the bracket 2 along the z-direction, that is, on the side of the bracket 2 closest to the window glass, the anti-collision beam 4 and at least one connecting plate 24 are at least partially overlapped in the y-direction, that is, there is a gap between the anti-collision beam 4 and the inner door panel 1 in the y-direction, and at least a portion of the connecting plate 24 is located between the anti-collision beam 4 and the inner door panel 1; on the other hand, in the lower half of the bracket 2 along the z-direction, that is, on the side of the bracket 2 away from the window glass, the support plate 22 and the bottom frame 12 are at least partially overlapped in the y-direction, and the sill beam 5 and the bottom frame 12 are at least partially overlapped in the y-direction, that is, the support plate 22 and the sill beam 5 are respectively located on the bottom frame. 12 Along the opposite sides in the y direction; under the action of dual angles, the upper part of the bracket 2 overlaps with the anti-collision beam 4 in the y direction, and the lower part overlaps with the bottom frame 12 and the sill beam 5 in the y direction. The bracket 2, the anti-collision beam 4, the inner door panel 1 and the sill beam 5 together form a large-area side impact protection structure. Therefore, when the vehicle is subjected to lateral force during driving, the anti-collision beam 4, the inner door panel 1, the bracket 2 and the sill beam 5 can jointly resist deformation, effectively ensuring the shape and structural stability of the support plate 22 and the inner door panel 1, improving the side impact resistance of the door, reducing the amount of intrusion of the window glass and the door into the vehicle, effectively reducing the risk of intrusion into the passenger compartment, and protecting the occupants from injury during a collision.

[0075] In this embodiment, as Figures 2 to 4 As shown, the first sub-plate 221 and the second sub-plate 222 are respectively provided with multiple ribs 27, which extend along the x-direction or y-direction respectively.

[0076] Specifically, multiple reinforcing ribs 27 are provided at the first sub-plate 221 and the second sub-plate 222. The multiple reinforcing ribs 27 extend along the x-direction or y-direction and are respectively set on the surface of the first sub-plate 221 and the second sub-plate 222 away from the inner panel 1 of the door, so as to further improve the structural strength of the support plate 22.

[0077] Specifically, the first sub-plate 221 is also provided with multiple through holes 28, which are spaced apart along the x-direction. The through holes 28 serve as electrophoresis holes, which can make the electrophoresis in the production process more complete, the electrophoretic film layer is thick enough, and improve the corrosion resistance of the support 2.

[0078] The specific assembly method of the door structure in this embodiment is as follows: First, the bracket 2 is fixed to the inner door panel 1, wherein the wing plate at the connecting plate 24 is attached to and fixed to the base plate 11 of the inner door panel 1, and the connecting part 29 at the second sub-plate 222 is attached to and fixed to the bottom frame 12 of the inner door panel 1; after the fixing is completed, a first cavity 25 and a second cavity 26 are formed between the bracket 2 and the inner door panel 1, which enhances the bending and torque resistance; then, the lifter 3 can be fixed to the bracket 2 and the inner door panel 1, and the mounting part 32 at the bottom of the slide rail 31 cooperates with and is fixed to the positioning part 21, which plays a role in constraining and positioning during the installation of the lifter 3; the two slide rails 31 of the lifter 3 cooperate with the two positioning parts 21 at the same bracket 2, shortening the dimensional chain length and reducing errors; finally, other components of the door structure can be installed to complete the assembly of the door structure.

[0079] The above embodiments are merely preferred embodiments provided to fully illustrate the present utility model, and the protection scope of the present utility model is not limited thereto. Equivalent substitutions or modifications made by those skilled in the art based on the present utility model are all within the protection scope of the present utility model.
