Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of automobile front door, specifically, the utility model relates to an automobile front door supporting structure. BACKGROUND

[0002] In the field of automobile manufacturing, the design and performance of automobile doors are crucial. The door is not only a passage for passengers to get in and out of the vehicle, but also plays a key role in the overall safety, sealing, sound insulation and appearance modeling of the vehicle. The front door outer panel, as an important part of the door, is directly exposed to the outside of the vehicle and bears various external forces, such as wind pressure, stone impact and possible collision impact during driving. The traditional connection method of the front door outer panel and the front door inner panel is relatively simple, and there is a lack of effective supporting structure between the front door outer panel and the front door inner panel. When the front door outer panel is subjected to external force, it is prone to deformation, affecting the appearance flatness and sealing of the door, and thus reducing the overall performance of the vehicle.

[0003] Chinese patent (publication number: 202827760U) discloses a reinforcing structure of an automobile outer panel and a vehicle. The reinforcing structure is a reinforcing film fixed to the inner side of the automobile outer panel. However, the reinforcing structure of the automobile outer panel cannot effectively cope with the collision impact during driving. SUMMARY

[0004] The utility model is to solve the above-mentioned problem and aims to provide an automobile front door supporting structure that can reduce the deformation of the front door outer panel when subjected to external force. To achieve the above-mentioned purpose, the utility model adopts the technical scheme of: an automobile front door supporting structure, comprising a front door inner panel and a front door outer panel, the front door inner panel and the front door outer panel are connected, and a supporting assembly is arranged between the front door inner panel and the front door outer panel.

[0005] The supporting assembly comprises an anti-collision plate, a first supporting plate and a second supporting plate. The anti-collision plate is arranged on the front door inner panel and extends from one end of the front door inner panel to the other end. The first supporting plate is connected to the anti-collision plate at one end and connected to the window of the front door inner panel. The second supporting plate is connected to the anti-collision plate at one end and connected to the bottom end of the front door inner panel at the other end.

[0006] A window frame reinforcing plate is connected to the window of the front door inner panel.

[0007] The long side of the first supporting plate is smaller than the long side of the window of the front door inner panel, and the first supporting plate and the front door inner panel share a set of molds.

[0008] The long side of the second supporting plate is smaller than the long side of the window of the front door outer panel, and the second supporting plate and the front door outer panel share a set of molds.

[0009] The reinforcing ribs are stamped on the surface of the anti-collision plate.

[0010] The anti-collision plate is made of HC340 / 590DP high-strength steel, and the first support plate and the second support plate are made of DC04 cold-rolled steel plate.

[0011] The contact surface of the second support plate and the outer plate of the front door is coated with a glue layer, and a fiber-reinforced strip is embedded in the glue layer.

[0012] The technical effect of the utility model is that the anti-collision plate extends from one end of the inner plate of the front door to the other end, and plays a core role in strengthening and supporting. When the vehicle is subjected to side collision, the anti-collision plate can directly bear and disperse most of the impact force, reducing the deformation degree of the inner plate and the outer plate of the front door, thereby effectively protecting the safety of passengers in the vehicle. One end of the first support plate is connected with the anti-collision plate, and the other end is connected to the window of the inner plate of the front door. Since the window area is relatively weak, it is easily affected by external forces such as vibration and wind pressure during vehicle driving. The first support plate mainly plays a role in strengthening the structural rigidity of the window area of the inner plate of the front door; one end of the second support plate is connected with the anti-collision plate, and the other end is connected with the bottom end of the inner plate of the front door. It is mainly used to strengthen the structural strength of the bottom end of the inner plate of the front door. The bottom end of the door is easily affected by the impact force generated by the knocking during getting on and off and the road bumping in daily use. The second support plate can effectively disperse these external forces through the synergistic effect with the anti-collision plate, preventing the bottom end of the inner plate of the front door from deforming, damaging, etc. The anti-collision plate adopts a self-symmetrical design, realizing the universality of the left front door of the vehicle and the right front door of the vehicle, and the first support plate and the second support plate adopt a self-symmetrical design, realizing the universality of the left front door of the vehicle and the right front door of the vehicle. At the same time, the welding of the left and right front doors does not interfere with each other. The first support plate and the inner plate of the front door share a set of molds during production, which to some extent reduces the production cost and improves the production efficiency. The second support plate and the outer plate of the front door share a set of molds during production, which to some extent reduces the production cost and improves the production efficiency.

[0020] The specific implementation of the present application is further explained in detail by the description of the embodiments with reference to the drawings, which aims to help the skilled in the art to have more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present application, and to facilitate its implementation.

[0021] As Figures 1-5 shown, an automobile front door support structure, including front door inner plate 1 and front door outer plate 2, front door inner plate 1 and front door outer plate 2 are connected, and support assembly 3 is arranged between front door inner plate 1 and front door outer plate 2. The automobile front door includes the left side front door of car and the right side front door of car, and the left side front door and the right side front door of car use same support assembly 3, and the structure of one side's front door is only shown in the embodiment, and support assembly 3 can strengthen the rigidity and appearance flatness of front door outer plate 2, and can reduce the deformation of front door outer plate 2 when front door outer plate 2 is subjected to external force.

[0022] The support assembly 3 comprises a collision plate 301, a first support plate 302 and a second support plate 303, all of which are square plates. The collision plate 301 is arranged on the front door inner panel 1 and extends from one end of the front door inner panel 1 to the other end. The first support plate 302 is connected to the collision plate 301 at one end and to the front door inner panel 1 at the window. The second support plate 303 is connected to the collision plate 301 at one end and to the bottom end of the front door inner panel 1 at the other end. The collision plate 301 extends from one end of the front door inner panel 1 to the other end, providing core reinforcement support. When the vehicle is subjected to a side collision, the collision plate 301 can directly bear and disperse most of the impact force, reducing the deformation of the front door inner panel 1 and the front door outer panel 2, thereby effectively protecting the safety of passengers inside the vehicle. The first support plate 302 is connected to the collision plate 301 at one end and to the front door inner panel 1 at the window at the other end. Since the window area is relatively weak, it is easily affected by external forces such as vibration and wind pressure during vehicle operation. The first support plate 302 mainly serves to strengthen the structural rigidity of the front door inner panel 1 at the window area. The second support plate 303 is connected to the collision plate 301 at one end and to the bottom end of the front door inner panel 1 at the other end. It is mainly used to strengthen the structural strength of the bottom end of the front door inner panel 1. The bottom end of the door is easily affected by impact forces caused by bumps when getting in and out of the vehicle and road bumps during daily use. The second support plate 303 can effectively disperse these external forces and prevent deformation and damage to the bottom end of the front door inner panel 1 through the synergistic effect with the collision plate 301. The collision plate 301 is designed to be self-symmetrical, allowing the left front door of the vehicle and the right front door of the vehicle to be universal. The first support plate 302 and the second support plate 303 are designed to be self-symmetrical, allowing the left front door of the vehicle and the right front door of the vehicle to be universal. The welding of the left and right front doors does not interfere with each other.

[0023] The front door inner panel 1 has a window frame reinforcement plate 4 connected to the window. The window frame reinforcement plate 4 is a square plate connected to the window of the front door inner panel 1. Its main function is to enhance the structural strength of the window frame. The window frame is a critical part of the door structure, as it not only ensures the normal installation and lifting of the window, but also bears various external forces during vehicle operation. The window frame reinforcement plate 4 can effectively improve the rigidity of the window frame, prevent deformation of the window frame when subjected to external forces, ensure the sealing and normal use of the window, and also help improve the safety and stability of the entire door in the window area.

[0024] The long side of the first support plate 302 is smaller than the long side of the window of the front door inner plate 1, allowing the first support plate 302 to be placed in the window area of the mold for producing the front door inner plate 1, and the first support plate 302 and the front door inner plate 1 share a set of molds. The first support plate 302 and the front door inner plate 1 share a set of molds during production, which to some extent reduces production costs and improves production efficiency. The mold for producing the front door inner plate 1 is used to produce the first support plate 302 in the window of the automobile front door inner plate 1, and the mold for producing the front door 1 inner plate can produce two first support plates 302 at a time.

[0025] The long side of the second support plate 303 is smaller than the long side of the window of the front door outer plate 2, allowing the second support plate 303 to be placed in the window area of the mold for producing the front door outer plate 2, and the second support plate 303 and the front door outer plate 2 share a set of molds. The second support plate 303 and the front door outer plate 2 share a set of molds during production, which to some extent reduces production costs and improves production efficiency. The mold for producing the front door outer plate 2 is used to produce the second support plate 303 in the window of the automobile front door outer plate 2, and the mold for producing the front door outer plate 2 can produce two second support plates 303 at a time.

[0026] The surface of the anti-collision plate 301 is stamped with reinforcing ribs 5. The reinforcing ribs 5 stamped on the surface of the anti-collision plate 301 further enhance the rigidity of the anti-collision plate 301 itself, making it less prone to buckling deformation when subjected to external forces, and greatly improving the impact resistance of the anti-collision plate 301.

[0027] The anti-collision plate 301 is made of HC340 / 590DP high-strength steel, and the first support plate 302 and the second support plate 303 are made of DC04 cold-rolled steel plate. The anti-collision plate 301 is made of HC340 / 590DP high-strength steel, which has good strength and toughness, and can better play a supporting and protective role on the overall structure of the door while ensuring the stability of its own structure. The first support plate 302 and the second support plate 303 are made of DC04 cold-rolled steel plate, which has good formability and certain strength, can meet the performance requirements of the door structure for this part, and is also convenient for processing and manufacturing.

[0028] The contact surface of the second support plate 303 and the front door outer plate 2 is coated with a glue layer, and a fiber-reinforced strip 6 is embedded in the glue layer. The glue layer is coated on the contact surface of the second support plate 303 and the front door outer plate 2, mainly serving as a connection and buffering function. It can tightly connect the second support plate 303 and the front door outer plate 2 together, so that they can deform cooperatively when subjected to external forces. The fiber-reinforced strip 6 is embedded in the glue layer, which can enhance the strength and toughness of the glue layer, prevent the glue layer from cracking due to external forces during long-term use, ensure the firm and reliable connection between the second support plate 303 and the front door outer plate 2, and further improve the stability and durability of the door structure.

[0029] Effects of embodiments

[0030] The anti-collision plate 301 extends from one end to the other end of the front door inner plate 1, and plays a role of core reinforcement support. When the vehicle is subjected to side impact, the anti-collision plate 301 can directly bear and disperse most of the impact force, reduce the deformation degree of the front door inner plate 1 and the front door outer plate 2, thereby effectively protecting the safety of the passengers in the vehicle. The first support plate 302 is connected to the anti-collision plate 301 at one end and to the window of the front door inner plate 1 at the other end. Since the window area is relatively weak, it is easily affected by external forces such as vibration and wind pressure during vehicle driving. The first support plate 302 mainly plays a role of reinforcing the structural rigidity of the window area of the front door inner plate 1; the second support plate 303 is connected to the anti-collision plate 301 at one end and to the bottom end of the front door inner plate 1 at the other end. It is mainly used to strengthen the structural strength of the bottom end of the front door inner plate 1. The bottom end of the door is easily affected by the impact force generated by the bumping when getting on and off the vehicle and the road bumps in daily use. The second support plate 303 can effectively disperse these external forces through the synergistic effect with the anti-collision plate 301, and prevent the bottom end of the front door inner plate 1 from deforming, damaging, etc. The anti-collision plate 301 adopts a self-symmetry design to realize the universality of the left front door of the vehicle and the right front door of the vehicle, and the first support plate 302 and the second support plate 303 adopt a self-symmetry design to realize the universality of the left front door of the vehicle and the right front door of the vehicle. At the same time, the welding of the left and right front doors does not interfere with each other. The first support plate 302 and the front door inner plate 1 share a set of molds during production, which to some extent reduces the production cost and improves the production efficiency. The second support plate 303 and the front door outer plate 2 share a set of molds during production, which to some extent reduces the production cost and improves the production efficiency.
