Description

TECHNICAL FIELD

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

[0002] Automobiles are extremely important means of transportation in modern life, and are widely used and have various types. Automobiles include passenger cars, commercial vehicles, public transportation, etc. They can be divided into fuel cars, electric cars and hybrid cars according to power.

[0003] In the prior art, a vehicle body includes a vehicle door, which includes a vehicle door outer panel and a vehicle door inner panel. The two are fixed by edge covering. After the inner panel is edge covered with the vehicle door outer panel, a cavity is formed. The cavity is filled with key components such as a front door outer panel reinforcement, a front door outer panel support plate, and a front door anti-collision beam to ensure that the strength of the vehicle door outer panel does not deform and the side collision strength of the vehicle is ensured. The vehicle door includes a window frame at the window frame for installing a vehicle window glass.

[0004] As the size of the vehicle door gradually increases, it brings many challenges to the structural design of the vehicle door. The previous structure often cannot adapt to the current rapid development of the design. The performance of the stiffness of the window frame front and rear corners has an important influence on the sealing of the vehicle door and the quality of opening and closing the door. In the prior art, the stiffness of the window frame front and rear corners cannot be improved by single structure and section optimization under the condition of shape locking. In the daily use process, the window frame will deform due to insufficient stiffness, which will cause the door to be unable to close or air leakage, and affect the user's use. CONTENT OF THE UTILITY MODEL

[0005] The present application at least solves one of the technical problems in the related art to some extent.

[0006] Therefore, the present application aims to provide a vehicle door assembly and a vehicle. The reinforcing structure improves the stiffness of the inner panel stand column and the inner panel main body, effectively enhances the structural strength of the vehicle door assembly, reduces the possibility of deformation when subjected to impact or other external forces, and improves the safety and durability of the vehicle door. The technical problem of poor stiffness of the connection between the inner panel stand column and the inner panel main body in the prior art is solved.

[0007] To achieve the above-mentioned purpose, the first aspect of the present application provides a vehicle door assembly, comprising:

[0008] a vehicle door inner panel, the vehicle door inner panel comprising an inner panel main body and an inner panel window frame; wherein the inner panel window frame comprises at least one inner panel stand column, and the inner panel stand column is connected with the inner panel main body; a side edge of the inner panel main body is provided with a first flange, and the inner panel stand column is provided with a second flange connected with the first flange;

[0009] a reinforcing structure, the reinforcing structure comprising:

[0010] a main body section for being arranged in abutment with the inner panel main body; the main body section at least partially abuts the first flange;

[0011] a support section connected with the main body section; the support section abuts and is connected to the inner panel upright; the support section at least partially abuts the second flange.

[0012] In the technical solution, the connection stability and rigidity of the inner panel main body and the inner panel upright are greatly enhanced by the reinforcing structure. The support section and the main body section are arranged at an angle, which can improve the bending resistance of the reinforcing structure. The reinforcing structure makes the connection between the inner panel upright and the inner panel main body more secure, and can better disperse and withstand external forces. The reinforcing structure improves the rigidity at the inner panel upright and the inner panel main body, effectively enhances the structural strength of the door assembly, reduces the possibility of deformation when subjected to impact or other external forces, and improves the safety and durability of the door.

[0013] In some embodiments of the present application, the main body section extends away from the first flange along the length direction of the door inner panel.

[0014] In the technical solution, the support section extends along the length direction of the inner panel upright, and the main body section extends away from the first flange, so that the reinforcing structure is approximately in the shape of a "cross", which can well meet the force transmission in different directions, ensure uniform force distribution in the cross section of the cavity in different directions, and arrange according to the required force distribution direction, which is very convenient and fast for improving the rigidity of the window frame.

[0015] In some embodiments of the present application, a first positioning part is arranged on the support section, and the first positioning part is used for positioning and / or connecting with the inner panel upright.

[0016] In the technical solution, the cooperation precision of the support section and the inner panel upright is improved, which is conducive to accurate cooperation with the performance connection structure of the window frame, ensures zero abutment connection of the welding point position, and is conducive to improving the welding precision. Not only does it facilitate accurate positioning of the reinforcing structure during installation, but also ensures that the reinforcing structure can be accurately abutted on the inner panel upright, ensuring the accuracy and consistency of the installation. Moreover, through the connection of the first positioning part and the inner panel upright, the connection stability between the support section and the inner panel upright is further enhanced. During vehicle driving, the door will be subjected to various vibrations and impact forces, and the first positioning part can effectively prevent relative displacement between the support section and the inner panel upright, thereby improving the rigidity at the inner panel upright and the inner panel main body and ensuring the structural strength of the door assembly.

[0017] In some embodiments of the present application, a first cavity is formed between the first positioning part and the inner panel upright.

[0018] In the technical scheme, the first cavity can play a buffering role, when the vehicle door is impacted by external force, the first cavity can absorb part of the energy, and reduce the impact force directly transmitted to the inner plate column and the inner plate body, thereby protecting the key structure of the vehicle door. On the other hand, the setting of the first cavity makes the support section part be bent, so as to improve the structural strength of the support section and the rigidity of the connection between the inner plate column and the inner plate body.

[0019] In some embodiments of the present application, a second positioning part is arranged on the main body section, which is used for positioning and / or connecting with the inner plate body.

[0020] In the technical scheme, the second positioning part is used for positioning other structures or through holes, or the cooperation precision of the main body section and the inner plate body is improved through the second positioning part, which is conducive to accurate cooperation with the performance connection structure of the window frame, ensures zero connection of the welding point position, and is conducive to improving the welding precision. Not only is the accurate positioning of the reinforcing structure in the installation process facilitated, but also it is ensured that the reinforcing structure can be accurately attached to the inner plate body, thereby ensuring the accuracy and consistency of the installation. Moreover, the connection stability between the main body section and the inner plate body is further enhanced through the connection of the second positioning part and the inner plate body. During vehicle driving, the vehicle door will be subjected to various vibrations and impact forces, and the second positioning part can effectively prevent relative displacement between the main body section and the inner plate body, thereby improving the rigidity of the inner plate column and the inner plate body and ensuring the structural strength of the vehicle door assembly.

[0021] In some embodiments of the present application, a second cavity is formed between the second positioning part and the inner plate body.

[0022] In the technical scheme, the second cavity can play a buffering role, when the vehicle door is impacted by external force, the second cavity can absorb part of the energy, and reduce the impact force directly transmitted to the inner plate column and the inner plate body, thereby protecting the key structure of the vehicle door. On the other hand, the setting of the second cavity makes the support section part be bent, so as to improve the structural strength of the support section and the rigidity of the connection between the inner plate column and the inner plate body.

[0023] In some embodiments of the present application, a vehicle door outer plate is further included, an edge of the vehicle door outer plate is connected with an edge of the vehicle door inner plate, and an installation cavity is formed between the vehicle door inner plate and the vehicle door outer plate; and the reinforcing structure is located in the installation cavity.

[0024] In the technical scheme, the design not only provides a relatively closed and stable mounting environment for the reinforcing structure, protecting the reinforcing structure from interference and damage from external factors. Moreover, the connection of the outer panel and the inner panel of the door further enhances the overall sealing and sound insulation effect of the door. The presence of the mounting cavity forms a relatively complete structural system inside the door, and the reinforcing structure can better work with the inner panel and the outer panel of the door to improve the stiffness of the inner panel column and the main body of the inner panel and the structural strength of the entire door assembly.

[0025] In some embodiments of the present application, a door reinforcing plate is arranged in the mounting cavity, one end of the door reinforcing plate is connected with the inner panel of the door, and the other end is connected with the reinforcing structure.

[0026] In the technical scheme, the door reinforcing plate plays an additional reinforcing role, further enhancing the connection strength and stability between the inner panel of the door and the reinforcing structure. Through the connection of the door reinforcing plate, external forces can be more effectively transmitted from the inner panel of the door to the reinforcing structure and then dispersed to the entire door structure, avoiding local stress concentration. This not only improves the stiffness of the inner panel column and the main body of the inner panel, but also enhances the overall performance of the entire door assembly when subjected to external forces, making the door more robust and durable.

[0027] In some embodiments of the present application, a support plate is arranged in the mounting cavity, and the support plate is connected with the reinforcing structure.

[0028] In the technical scheme, when the door is subjected to external forces, the support plate can assist the reinforcing structure to better withstand and disperse forces, further improving the stiffness of the inner panel column and the main body of the inner panel. At the same time, the arrangement of the support plate can also optimize the structural layout inside the door, making the overall structure of the door more reasonable and improving the structural strength and reliability of the door assembly.

[0029] In addition, the present application also provides a vehicle comprising:

[0030] A vehicle body is provided with the door assembly as described above; the door assembly is hinged to the vehicle body.

[0031] In the technical scheme, the vehicle with the door assembly having high stiffness and strength can better resist various external force impacts such as collision, jolt, etc. during driving. The high stiffness and strength of the door can ensure that the door is not easily deformed when subjected to external forces, thereby improving the passive safety of the vehicle. At the same time, the stable door structure also helps to improve the overall sealing and sound insulation effect of the vehicle, providing a more comfortable driving environment for passengers. Moreover, the hinged connection of the door assembly and the vehicle body ensures the normal opening and closing function of the door, making the use of the vehicle more convenient and reliable.

[0032] As can be seen from the above technical solutions, additional aspects and advantages of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application.

[0045] In the following, the present application is specifically described by exemplary embodiments. However, it should be understood that the elements, structures and features in one embodiment can also be beneficially combined into other embodiments without further description.

[0046] It should be noted that in the automotive field, the vehicle body includes a door, the door includes a door outer panel and a door inner panel, which are fixed by edge covering. After the inner panel is edge covered with the door outer panel, there is a cavity, which is filled with key parts such as the first door reinforcement plate of the front door outer panel, the support plate of the front door outer panel, and the front door anti-collision beam to ensure that the strength of the door outer panel will not be deformed, and to ensure the side impact strength of the vehicle. Among them, the door includes a window frame, which is used to install the window glass.

[0047] In the prior art, deformation occurs at the window frame due to insufficient rigidity, leading to situations such as the door being unable to be closed or air leakage, affecting user use.

[0048] Based on this, the application provides a vehicle door assembly and a vehicle, which achieve the effect of improving the structural strength of the window by setting a reinforcing structure, solving the problem of deformation of the window frame in the prior art.

[0049] In the following, the embodiments of the application will be described in detail with reference to the accompanying drawings.

[0050] As shown in the accompanying Figures 1 to 3 In one illustrative embodiment of the vehicle door assembly and the vehicle of the application, the vehicle door assembly includes an inner door panel. The main carrier of the vehicle door assembly structure provides mounting points for all accessories on the door, and through other reinforcing structures 300 on the door, the force channel is distributed at different positions, effectively distributing the state of the force on the door, which is the main structure of the vehicle door assembly, and forms the vehicle door assembly after being combined with the outer door panel. At the same time, local reinforcing ribs can be made on the inner door panel.

[0051] In some embodiments, the inner door panel includes an inner panel body 100 and an inner panel window frame 200. The inner panel window frame 200 surrounds the window area and tightly cooperates with the window glass, plays a sealing role, prevents dust and moisture from the outside from entering the vehicle, and at the same time provides a precise guide rail for the lifting of the window glass, ensuring smooth operation of the window.

[0052] In some embodiments, the inner panel window frame 200 includes at least one inner panel upright 201, and the inner panel upright 201 is connected with the inner panel body 100. In general, one window frame of a vehicle includes two left and right inner panel uprights 201. The space between the two inner panel uprights 201 is used for the lifting of the window glass. However, in some vehicles, the window frame can only have one inner panel upright 201.

[0053] In some embodiments, the inner panel body 100 and the inner panel window frame 200 are integrally connected. In this way, the connection strength and rigidity between the inner panel body 100 and the inner panel window frame 200 are improved, and the possibility of deformation of the inner panel window frame 200 is reduced. Specifically, the inner panel body 100 and the inner panel upright 201 are integrally formed.

[0054] In another embodiment, the inner panel body 100 and the inner panel upright 201 are a split structure but are integrally connected, that is, the inner panel body 100 and the inner panel upright 201 can be connected by welding, fusion, etc.

[0055] In another embodiment, the inner panel body 100 and the inner panel upright 201 can be detachably connected, and the connection methods include but are not limited to bolts, buckles, screws, rivets, etc.

[0056] In some embodiments, the inner plate window frame 200 further comprises an inner cross beam 203, which is spaced apart from the inner plate body 100, and two ends of the inner cross beam 203 are connected with the two inner plate columns 201 respectively. The inner cross beam 203, the two inner plate columns 201 and the inner plate body 100 form a vehicle window area.

[0057] In some embodiments, the side edge of the inner plate body 100 is provided with a first flange 101, and the inner plate column 201 is provided with a second flange 202 connected with the first flange 101. It can be understood that if the inner plate column 201 is integrally formed with the inner plate body 100, the first flange 101 and the second flange 202 are also integrally formed.

[0058] In some embodiments, the vehicle door assembly further comprises a reinforcing structure 300. The reinforcing structure 300 improves the structural strength of the connection between the inner plate column 201 and the inner plate body 100, so as to avoid deformation of the inner plate window frame 200.

[0059] Please refer to Figures 1 to 7 In some embodiments, the reinforcing structure 300 comprises a main body section 301 and a support section 302. The main body section 301 is arranged to be attached to the inner plate body 100, and the main body section 301 is at least partially attached to the first flange 101. The support section 302 is connected with the main body section 301, and the support section 302 is attached to and connected with the inner plate column 201, and the support section 302 is at least partially attached to the second flange 202.

[0060] Through the above scheme, the connection stability and rigidity of the inner plate body 100 and the inner plate column 201 are greatly improved by the reinforcing structure 300. The support section 302 and the main body section 301 are arranged at an angle, which can improve the bending resistance of the reinforcing structure 300. The reinforcing structure 300 makes the connection between the inner plate column 201 and the inner plate body 100 more firm, and can better disperse and withstand external forces. The reinforcing structure 300 improves the rigidity of the inner plate column 201 and the inner plate body 100, effectively enhances the structural strength of the vehicle door assembly, reduces the possibility of deformation when subjected to impact or other external forces, and improves the safety and durability of the vehicle door.

[0061] In some embodiments, the length direction of the support section 302 is the same as the extension direction of the corresponding inner plate column 201, and the support section 302 is attached to the inner plate column 201 to support the inner plate column 201.

[0062] In some embodiments, the main body section 301 extends along the length direction of the inner door panel away from the side of the first flange 101. The support section 302 extends along the length direction of the inner panel pillar 201, and the main body section 301 extends away from the first flange 101 to make the reinforcing structure 300 generally a "cross" structure, which can well meet the force transmission in different directions, ensure the cavity section in different directions, and make the force distribution uniform. The reinforcing structure 300 is arranged according to the required force distribution direction, which is very convenient and fast for improving the stiffness performance of the window frame.

[0063] In some embodiments, the outer door panel is further included, the edge of the outer door panel is connected with the edge of the inner door panel, and the mounting cavity is formed between the inner door panel and the outer door panel; and the reinforcing structure 300 is located in the mounting cavity. This design not only provides a relatively closed and stable mounting environment for the reinforcing structure 300, and protects the reinforcing structure 300 from interference and damage from external factors. Moreover, the connection of the outer door panel and the inner door panel further enhances the overall sealing and sound insulation effect of the door. The existence of the mounting cavity forms a relatively complete structural system inside the door, and the reinforcing structure 300 can better work with the inner door panel and the outer door panel to improve the stiffness of the inner panel pillar 201 and the inner panel main body 100 and the structural strength of the entire door assembly.

[0064] In some embodiments, the outer door panel includes an outer panel main body and an outer panel window frame, and the outer door panel is the outer structure of the automobile door, which is an important part of the appearance of the vehicle and is directly related to the overall modeling and aesthetics of the vehicle. The outer door panel is usually stamped from high-strength steel, aluminum alloy and other materials, has good strength and rigidity, and can effectively resist external impact to protect the internal structure of the door and the safety of passengers.

[0065] In some embodiments, the outer panel window frame includes at least one outer panel pillar 201 connected with the outer panel main body.

[0066] In some embodiments, the outer panel main body and the outer panel window frame are integrally connected to improve the connection strength and rigidity between the outer panel main body and the outer panel window frame and reduce the possibility of deformation of the outer panel window frame. Specifically, the outer panel main body and the outer panel pillar 201 are integrally formed.

[0067] In another embodiment, the outer panel main body and the outer panel pillar 201 are a split structure but are integrally connected, that is, the outer panel main body and the outer panel pillar 201 can be connected by welding, fusion, etc.

[0068] In another embodiment, the outer panel main body and the outer panel pillar 201 can be detachably connected, and the connection methods include but are not limited to bolts, buckles, screws, rivets, etc.

[0069] In some embodiments, the outer plate window frame further comprises an outer crossbeam, which is spaced apart from the outer plate body and connected to the two outer plate uprights 201 at both ends.

[0070] In some embodiments, the inner plate window frame 200 and the outer plate window frame 200 are connected to form a window frame. The inner plate upright 201 and the outer plate upright 201 are connected to form an upright 201 of the vehicle.

[0071] In some embodiments, the support section 302 of the reinforcing structure 300 is located between the outer plate upright 201 and the inner plate upright 201. The body section 301 of the reinforcing structure 300 is located between the outer plate body and the inner plate body 100.

[0072] In some embodiments, the inner plate body 100 and the outer plate body are close to the edge of the window frame, which is a window sill. The upper part of the body section 301 extending away from the first flange 101 is connected to the window sill, and the body section 301 is connected to the hem of the outer plate of the door through a welding point.

[0073] In some embodiments, the connection between the reinforcing structure 300 and the inner door panel is preferably welding. The advantage of welding is that it has high connection strength and good durability, which can effectively enhance the connection stability between the reinforcing structure 300 and the inner door panel, and ensure that there is no loosening or separation when various external forces are applied during the driving of the vehicle, greatly improving the overall strength and safety of the door.

[0074] In other embodiments, the connection between the reinforcing structure 300 and the inner door panel includes but is not limited to bolt connection, rivet connection, fusion, buckle connection.

[0075] Please refer to Figures 3 to 7 In some embodiments, the support section 302 is provided with a first positioning part 400, which is used for positioning with the inner plate upright 201.

[0076] In some embodiments, the first positioning part 400 can also be connected with the inner plate stand column 201. The cooperation accuracy of the support section 302 and the inner plate stand column 201 is improved, which is conducive to the accurate cooperation of the performance connection structure with the window frame, ensures the zero connection of the welding point position, and is conducive to the improvement of the welding accuracy. Not only is it convenient for the accurate positioning of the reinforcing structure 300 during installation, but also ensures that the reinforcing structure 300 can be accurately attached to the inner plate stand column 201, thereby ensuring the accuracy and consistency of the installation. Moreover, through the connection of the first positioning part 400 and the inner plate stand column 201, the connection stability between the support section 302 and the inner plate stand column 201 is further enhanced. During vehicle driving, the door will be subjected to various vibrations and impact forces, and the first positioning part 400 can effectively prevent relative displacement between the support section 302 and the inner plate stand column 201, thereby improving the stiffness of the inner plate stand column 201 and the inner plate main body 100 and ensuring the structural strength of the door assembly.

[0077] In some embodiments, a first cavity is formed between the first positioning part 400 and the inner plate stand column 201. The first cavity can play a buffering role. When the door is subjected to external impact, the first cavity can absorb part of the energy, thereby reducing the direct transmission of the impact force to the inner plate stand column 201 and the inner plate main body 100, thereby protecting the key structure of the door. On the other hand, the setting of the first cavity causes the support section 302 to be partially bent, thereby improving the structural strength of the support section 302 and the stiffness of the connection between the inner plate stand column 201 and the inner plate main body 100.

[0078] In some embodiments, the first cavity is recessed in a direction away from the inner plate of the door.

[0079] In some embodiments, the first positioning part 400 is preferably a positioning hole.

[0080] In some embodiments, a second positioning part 500 is arranged on the main body section 301, and the second positioning part 500 is used for positioning with the inner plate main body 100.

[0081] In some embodiments, the second positioning part 500 is connected with the inner panel body 100. Through the second positioning part 500 for other structure positioning or via hole, or through the second positioning part 500, the matching precision of the main body section 301 and the inner panel body 100 is improved, which is conducive to the accurate matching of the performance connection structure of the window frame, ensures the zero connection of the welding point position, and is conducive to the improvement of the welding precision. Not only is it convenient for the accurate positioning of the reinforcing structure 300 in the installation process, but also ensures that the reinforcing structure 300 can be accurately attached to the inner panel body 100, thereby ensuring the accuracy and consistency of the installation. Moreover, through the connection of the second positioning part 500 and the inner panel body 100, the connection stability between the main body section 301 and the inner panel body 100 is further enhanced. During vehicle driving, the door will be subjected to various vibrations and impact forces, and the second positioning part 500 can effectively prevent the relative displacement between the main body section 301 and the inner panel body 100, thereby improving the stiffness of the inner panel pillar 201 and the inner panel body 100 at the position, and ensuring the structural strength of the door assembly.

[0082] In some embodiments, a second cavity is formed between the second positioning part 500 and the inner panel body 100. Through the second cavity, a buffering effect can be achieved. When the door is subjected to external impact, the second cavity can absorb part of the energy, reducing the direct transmission of the impact force to the inner panel pillar 201 and the inner panel body 100, thereby protecting the key structure of the door. On the other hand, the setting of the second cavity causes the main body section 301 to be partially bent, thereby improving the structural strength of the main body section 301 and the stiffness of the connection between the inner panel pillar 201 and the inner panel body 100.

[0083] In some embodiments, the second cavity is recessed away from the door inner panel by the second positioning part 500.

[0084] In some embodiments, the second positioning part 500 can be a process via hole. This hole serves as a process via hole for installing other accessories at the position of the door window frame, or a positioning via hole for other structures.

[0085] In some embodiments, the number of second positioning parts 500 can be multiple.

[0086] In some embodiments, a third positioning part 600 is provided on the main body section 301, and the third positioning part 600 is used for positioning with the inner panel body 100.

[0087] In some embodiments, the third positioning part 600 is connected with the inner panel body 100. The third positioning part 600 is preferably a positioning hole, which ensures the improvement of the matching precision of the reinforcing structure 300 and the window frame, is conducive to the accurate matching of the performance connection structure of the reinforcing structure 300 and the window frame, ensures the connection of the welding point position, and is conducive to the improvement of the welding precision.
