[0026] See also Figure 1 and Figure 2 , Figure 1 is a schematic diagram of the overall structure of an embodiment of a vehicle door structure of the present application, wherein the vehicle door structure includes a mounting bracket; Figure 2 yes Figure 1 Schematic diagram of the three-dimensional structure of the mounting bracket.

[0027] An embodiment of the present application provides a vehicle door structure 10. The vehicle door structure 10 includes an inner panel 11, an inner panel reinforcement plate 12, an outer panel reinforcement plate 13 and a mounting bracket 14. The inner panel reinforcement plate 12 is connected to the inner panel 11. The outer panel reinforcement plate 13 is located on the outer side of the inner panel reinforcement plate 12 facing away from the inner panel 11. The mounting bracket 14 includes a mounting body 141, a first leg 142 and a second leg 143, wherein the first leg 142 and the second leg 143 are both formed by the mounting body 141 protruding toward the same side thereof and extending, wherein the mounting body 141 is fixed to the outer panel reinforcement plate 13. The first leg 142 and the second leg 143 are respectively fixed to the inner panel 11 and the inner panel reinforcement plate 12, and a first cavity 144 is formed between the mounting body 141 and the inner panel 11 and the inner panel reinforcement plate 12.

[0028] As can be seen from the above structure, the inner panel reinforcement plate 12 can play a certain role in reinforcing the structure of the inner panel 11, so as to improve the structural rigidity of the inner panel 11. The first leg 142 and the second leg 143 can play a certain role in supporting the mounting body 141. The connection between the inner panel 11, the inner panel reinforcement plate 12 and the outer panel reinforcement plate 13 and the mounting bracket 14 can keep the mounting bracket 14 stable when installed on the vehicle body. Furthermore, the mounting body 141 and the inner panel 11 and the inner panel reinforcement plate 12 are respectively fixed to the inner panel 11 and the inner panel reinforcement plate 12 by the first leg 142 and the second leg 143, thereby forming a first cavity 144. The arrangement of this structure forms a box structure between the inner panel 11, the inner panel reinforcement plate 12, the outer panel reinforcement plate 13 and the mounting bracket 14 through the first cavity 144. The cavity structure of the box structure provides a buffer space, and the air in the cavity helps to reduce vibration. Therefore, the box structure has a good buffering and vibration reduction effect, thereby effectively improving the stiffness and mounting mode of the mounting point of the door structure 10, and the vibration generated during the driving of the vehicle can be effectively dispersed, thereby effectively avoiding the vibration of the door structure 10 caused by the driving of the vehicle, so as to greatly improve driving safety and extend the service life of the door structure 10.

[0029] See also Figures 1 to 4 , Figure 3 It is a partial structural schematic diagram of an embodiment of a vehicle door structure of the present application; Figure 4 yes Figure 3A partial enlarged structural diagram of the middle A. In one embodiment of the present application, the mounting body 141 is provided with a recessed area 145, and a second cavity 146 is formed between the recessed area 145 and the outer panel reinforcement plate 13. Since the outer panel reinforcement plate 13 is subjected to a large impact force due to shaking during high-speed driving of the vehicle, and by forming the second cavity 146, the cavity structure of the second cavity 146 can provide a buffer space, and the air in the cavity helps to reduce vibration. Therefore, the second cavity 146 has a good buffering and vibration reduction effect, thereby effectively improving the structural rigidity of the mounting bracket 14, avoiding the shaking of the door structure 10 caused by the vehicle during driving, so as to better improve driving safety.

[0030] In one embodiment of the present application, a boss 147 is provided on the side of the mounting body 141 away from the first leg 142. The mounting bracket 14 also includes a fixing portion 148, which is connected to the mounting body 141 and is formed in a convex manner in the direction of the same side as the boss 147; the fixing portion 148 is fixedly connected to the outer plate reinforcement plate 13. A recessed area 145 is formed between the fixing portion 148 and the boss 147. The arrangement of the boss 147 and the fixing portion 148 can increase the contact area between the mounting body 141 and the outer plate reinforcement plate 13, thereby strengthening the connection strength between the mounting bracket 14 and the outer plate reinforcement plate 13. The recessed area 145 is formed between the fixing portion 148 and the boss 147, thereby effectively dispersing the impact force of the outer plate reinforcement plate 13 due to shaking, thereby reducing the magnitude of the impact force of the mounting bracket 14 due to shaking, thereby effectively improving the structural rigidity of the mounting bracket 14, avoiding the shaking of the door structure 10 caused by the vehicle during driving, and better improving driving safety.

[0031] The fixing portion 148 and the outer panel reinforcement plate 13 may be connected by welding, or the fixing portion 148 and the outer panel reinforcement plate 13 may be connected by bolts, which is not limited here.

[0032] Furthermore, in order to further improve the structural rigidity of the mounting bracket 14, in one embodiment of the present application, a plurality of first reinforcing ribs 149 are formed in the recessed area 145. The first reinforcing ribs 149 can further enhance the structural strength of the recessed area 145, thereby effectively increasing the structural rigidity of the mounting bracket 14, reducing the shaking of the mounting bracket 14 caused by the driving of the vehicle, and improving driving safety.

[0033] In one embodiment of the present application, the mounting body 141 further includes a connecting plate 150, which is connected to the mounting body 141 and forms a step with the boss 147. The outer panel reinforcement plate 13 protrudes inwardly and is connected to the connecting plate 150, and a third cavity 151 is formed between the outer panel reinforcement plate 13 and the connecting plate 150. The structure of the connecting plate 150 can increase the contact area between the mounting bracket 14 and the outer panel reinforcement plate 13, thereby effectively increasing the connection strength between the mounting bracket 14 and the outer panel reinforcement plate 13. The structure of the third cavity 151 provides a buffer space, and the air in the cavity helps to reduce vibration, which can effectively disperse the impact force of the outer panel reinforcement plate 13 due to shaking, so as to reduce the magnitude of the impact force of the mounting bracket 14 due to shaking, thereby effectively improving the structural rigidity of the mounting bracket 14, avoiding the shaking of the door structure 10 caused by the vehicle during driving, and better improving driving safety.

[0034] The connecting plate 150 and the outer plate reinforcement plate 13 may be connected by welding, or they may be connected by bolts, which is not limited here.

[0035] Furthermore, the boss 147 is provided with a first mounting hole 152 and a first limiting hole 153, the outer plate reinforcement plate 13 is provided with a second mounting hole (not shown in the figure) corresponding to the first mounting hole 152, and a second limiting hole (not shown in the figure) corresponding to the first limiting hole 153, the first mounting hole 152 and the second mounting hole are used to connect with the external structure, and the first limiting hole 153 and the second limiting hole are used to position the external structure. In the process of connecting the external structure, the bolts can be passed through the second limiting hole and the first limiting hole 153 in sequence to position the external structure, and after the external structure is positioned, the bolts can be passed through the second mounting hole and the first mounting hole 152 in sequence to fix the external structure to the mounting bracket 14, thereby achieving the installation of the external structure. By providing the first limiting hole 153 and the second limiting hole, the installation process of the staff can be facilitated and the installation efficiency can be improved, and the first mounting hole 152 and the second mounting hole can play a fixing role on the external structure to ensure the stability of the connection of the external structure.

[0036] Among them, the first mounting hole 152 is a round hole, the second mounting hole corresponds to the first mounting hole 152 and is also a round hole, the first limiting hole 153 is a strip hole, the second limiting hole corresponds to the first limiting hole 153 and is also a strip hole. Of course, in some other embodiments, the first mounting hole 152 and the second mounting hole can also be strip holes, which is not limited here.

[0037] The number of the first mounting holes 152 can be multiple, such as 2, 3, 4, etc., and the number of the second mounting holes corresponds to the number of the first mounting holes 152. Preferably, in the present application, the number of the first mounting holes 152 is 3, and the three first mounting holes 152 are distributed in a triangle. Since the triangular structure has strong stability, the three first mounting holes 152 are distributed in a triangle, which can make the connection between the boss 147 and the outer panel reinforcement plate 13 more stable.

[0038] In an embodiment of the present application, a second reinforcing rib 154 is provided on at least any one of the first leg 142 and the second leg 143. The provision of the second reinforcing rib 154 can further enhance the structural strength of the first leg 142 and / or the second leg 143, so as to improve the structural rigidity of the mounting bracket 14, thereby effectively improving the rigidity and mounting mode of the mounting point of the door structure 10, and effectively dispersing the vibration generated during the driving of the vehicle, thereby effectively avoiding the vibration of the door structure 10 caused by the driving of the vehicle, so as to greatly improve driving safety.

[0039] The second reinforcing rib 154 may be provided only on the first leg 142 , or only on the second leg 143 , or both on the first leg 142 and the second leg 143 , which is not limited here.

[0040] In one embodiment of the present application, the first leg 142 includes a first supporting portion 1421 and a first connecting portion 1422, wherein the first supporting portion 1421 is connected to the installation body 141, and the first connecting portion 1422 is connected to the first supporting portion 1421, and the first connecting portion 1422 is used to connect to the inner plate reinforcing plate 12. The first supporting portion 1421 can be used to prop up the installation body 141 so that a cavity is formed between the installation body 141 and the inner plate reinforcing plate 12, thereby strengthening the structural rigidity of the first leg 142. The first connecting portion 1422 is connected to the inner plate reinforcing plate 12, and the contact area between the first leg 142 and the inner plate reinforcing plate 12 can be increased, thereby effectively increasing the connection strength between the first leg 142 and the inner plate reinforcing plate 12. The second leg 143 includes a second supporting portion 1431 and a second connecting portion 1432. The second supporting portion 1431 is connected to the installation body 141, and the second connecting portion 1432 is connected to the second supporting portion 1431. The second supporting portion 1431 is used to connect to the inner panel 11. The second supporting portion 1431 can be used to prop up the installation body 141 so that a cavity is formed between the installation body 141 and the inner panel 11. The cavity structure provides a buffer space, and the air in the cavity helps to reduce vibration, thereby increasing the structural rigidity of the second leg 143. The second connecting portion 1432 is connected to the inner panel 11, which can effectively increase the connection strength between the second leg 143 and the inner panel 11 by increasing the contact area between the second leg 143 and the inner panel 11. Furthermore, a second reinforcing rib 154 is provided on at least any one of the first support portion 1421 and the second support portion 1431. The structure of the second reinforcing rib 154 can further enhance the structural strength of the first support portion 1421 and / or the second support portion 1431, so as to effectively improve the structural stiffness of the mounting bracket 14, thereby effectively improving the stiffness and mounting mode of the mounting point of the door structure 10. The vibration generated during the driving of the vehicle can be effectively dispersed, so as to effectively avoid the shaking of the door structure 10 caused by the driving of the vehicle, thereby greatly improving driving safety.
