Description

Technical Field

[0001] The utility model relates to the technical field of vehicles, in particular to a vehicle door and an automobile. Background Art

[0002] In order to protect the safety of the vehicle occupants, an anti-collision beam is usually provided inside the vehicle door to increase the strength of the vehicle door. In existing automobiles, one side of the vehicle door is hinged to the vehicle body through upper and lower hinge brackets. The vehicle door includes an outer panel and an inner panel of the vehicle door. The anti-collision beam is arranged between the outer panel and the inner panel of the vehicle door. One end of the anti-collision beam is connected to the inner panel of the vehicle door through a door beam bracket, and the door beam bracket is arranged between the upper and lower hinge brackets. The other end of the anti-collision beam is connected to the inner panel of the vehicle door through another door beam bracket, and the door beam bracket is arranged on one side behind the automobile and near the lower edge. Thus, the height of the anti-collision beam towards the hinge end can be greater than that of the other end, making the anti-collision beam in an up-and-down inclined state. The anti-collision beam is of a tubular structure. When water enters the inside of the vehicle door, if the inclination angle of the anti-collision beam is relatively large, the water can flow in from the higher end of the anti-collision beam and flow out from the lower end of the anti-collision beam, thereby avoiding water accumulation inside the anti-collision beam and causing rust. However, when the inclination angle of the anti-collision beam is relatively small, or there is a water-retaining structure such as a downward bend at the middle position of the anti-collision beam, it may cause water accumulation inside the anti-collision beam, resulting in rust of the anti-collision beam, thereby affecting the structure of the vehicle door and driving safety. Therefore, there is an urgent need for a vehicle door and an automobile that can prevent water from flowing into the anti-collision beam from the end of the anti-collision beam when water enters the inside of the vehicle door, so as to avoid water accumulation inside the anti-collision beam and rust of the anti-collision beam. Summary of the Utility Model

[0003] This application provides a vehicle door and an automobile that can prevent water from flowing into the anti-collision beam from the end of the anti-collision beam when water enters the inside of the vehicle door, so as to avoid water accumulation inside the anti-collision beam and rust of the anti-collision beam.

[0004] The first aspect of this application provides a vehicle door, including: an inner panel of the door and an anti-collision beam; the anti-collision beam is installed on the inner panel of the door; a water-blocking structure is provided at the end of the anti-collision beam.

[0005] Thus, by providing a water-blocking structure at the end of the anti-collision beam, when water enters the vehicle door, the water can be blocked by the water-blocking structure, preventing the water from entering the anti-collision beam from the end of the anti-collision beam. Thereby, water accumulation inside the anti-collision beam can be avoided, rust of the anti-collision beam can be avoided, and the influence of rust of the anti-collision beam on the strength of the vehicle door structure and driving safety can also be avoided.

[0006] As a possible implementation manner of the first aspect, the water-blocking structure is connected to the inner panel of the door, and the anti-collision beam is installed on the inner panel of the door through the water-blocking structure.

[0007] As described above, the water-blocking structure can be reused, and the anti-collision beam is installed on the inner door panel through the water-blocking structure. Thereby, the number of parts can be reduced, the installation difficulty can be lowered, and the cost of the car door can be reduced.

[0008] As a possible implementation of the first aspect, it further includes an outer door panel; the outer door panel is connected to the outer side of the inner door panel; and a first mounting structure; the first mounting structure is connected to the end of the anti-collision beam; the first mounting structure has a first connecting portion, and the first connecting portion is fixedly connected to the outer door panel to form a water-blocking structure.

[0009] As described above, the first mounting structure is connected to the outer door panel through the first connecting portion, so that the anti-collision beam can be fixedly connected to the outer door panel. By making the first connecting portion form a water-blocking structure, the first mounting structure can be reused. While the anti-collision beam is fixed on the outer door panel through the first mounting structure, the first connecting portion forms a water-blocking structure. After water enters the car door, it can prevent water from flowing into the anti-collision beam from the end of the anti-collision beam. Thereby, it can prevent water accumulation inside the anti-collision beam, prevent the anti-collision beam from rusting, and can also prevent the rusting of the anti-collision beam from affecting the door structure and driving safety.

[0010] As a possible implementation of the first aspect, the upper end of the first connecting portion is connected to the inner side of the outer door panel, and the first connecting portion is inclined downward and gradually inward in the direction of the vehicle.

[0011] As described above, by making the first connecting portion inclined downward and gradually inward in the direction of the vehicle, after water enters the car door, the first connecting portion can guide the water, preventing water from flowing into the anti-collision beam from the end of the anti-collision beam.

[0012] As a possible implementation of the first aspect, in the thickness direction of the car door, the cross-sectional shape of the first connecting portion is wavy.

[0013] As described above, by making the first connecting portion wavy, when the first connecting portion guides the water, it can increase the path length of the water flow, reduce the speed of the water flowing downward, reduce the possibility of water droplets quickly impacting other components below the anti-collision beam, and can also reduce the splashing water droplets generated after dripping on other components, thereby reducing the possibility of rust and damage to other components inside the car door.

[0014] As a possible implementation of the first aspect, the first mounting structure further has a second connecting portion, the upper part of the second connecting portion is connected to the lower part of the first connecting portion, and the end of the anti-collision beam is connected to the second connecting portion and is located between the outer door panel and the second connecting portion.

[0015] As described above, since the end of the anti-collision beam is connected to the second connecting portion and is located between the outer door panel and the second connecting portion, the end of the anti-collision beam can be located below the first connecting portion. Thus, when water enters the door and flows downward, the first connecting portion can guide the water so that the water flows away from above the end of the anti-collision beam, preventing the water from flowing into the anti-collision beam from the end of the anti-collision beam.

[0016] As a possible implementation of the first aspect, in the plane where the inner door panel is located, the projection of the outer edge of the end of the anti-collision beam is within the projected area of the first mounting structure.

[0017] As described above, by making the projection of the outer edge of the end of the anti-collision beam within the projected area of the first mounting structure, a gap can be formed between the end of the anti-collision beam and the inner door panel. Thus, it is possible to prevent water flowing down along the inner door panel from flowing into the anti-collision beam from the end of the anti-collision beam, thereby improving the waterproof effect on the end of the anti-collision beam.

[0018] As a possible implementation of the first aspect, the first mounting structure further includes a fixing portion, and the fixing portion is connected to the first connecting portion and fixedly connected to the inner door panel.

[0019] As a possible implementation of the first aspect, the angle between the first connecting portion and the fixing portion is set as α, where 0° ≤ α ≤ 180°.

[0020] As described above, due to the limited thickness of the door, the gap between the inner door panel and the outer door panel is small. If the connecting end and the fixing portion are on the same plane, it is difficult to fix the fixing portion on the opposite side surfaces of the inner door panel and the outer door panel. Additionally, usually, the inner door panel of the door bends outward at the edge of the door and joins the outer door panel. By setting the fixing portion and the connecting end at an angle, the installation difficulty of the first mounting structure can be reduced.

[0021] As a possible implementation of the first aspect, it further includes a door hinge, and the door hinge is connected to the first mounting structure and is located on the outer side of the inner door panel close to the vehicle body.

[0022] As described above, by installing the door hinge on the first mounting structure, the first mounting structure can be reused to install the door hinge, that is, the anti-collision beam and the door hinge can be installed on the first mounting structure simultaneously. Thus, it is not necessary to separately set up a mounting structure for specifically installing the door hinge, which can reduce the number of parts of the door, reduce the weight and production cost of the door, and simplify the installation steps.

[0023] As a possible implementation of the first aspect, it further includes a second mounting structure, and one end of the anti-collision beam away from the water blocking structure is fixed to the inner door panel through the second mounting structure.

[0024] As described above, by providing the second mounting structure, the bumper beam can be fixed at both ends of the bumper beam together with the first mounting structure. Thereby, the stability and structural strength of the bumper beam can be improved.

[0025] As a possible implementation of the first aspect, the end of the bumper beam is an open structure.

[0026] As described above, by setting the end of the bumper beam as an open structure, the structure of the bumper beam can be simplified, and the weight and cost of the bumper beam can be reduced. In addition, by setting the end of the bumper beam as an open structure, it is also convenient for air to enter the interior of the bumper beam from the end, which is beneficial to keeping the interior of the bumper beam dry.

[0027] As a possible implementation of the first aspect, the bumper beam is inclined in the height direction of the car door, and the water blocking structure is located at the higher end of the bumper beam.

[0028] As described above, by setting the water blocking structure at the higher end of the bumper beam, water can be prevented from entering the bumper beam from the end of the bumper beam.

[0029] As a possible implementation of the first aspect, the bumper beam is an open tubular structure; in the height direction of the car door, the bumper beam is inclined; the car door further includes an outer door panel; the outer door panel is connected to the outside of the inner door panel; the car door further includes a first mounting structure; the first mounting structure is located at the higher end of the bumper beam; the first mounting structure has a first connecting portion, a second connecting portion, and a fixing portion; the lower part of the first connecting portion is connected to the upper part of the second connecting portion, and the sides of the first connecting portion and the second connecting portion are connected to the fixing portion; the first connecting portion is inclined downward and inward toward the vehicle from top to bottom; the upper part of the first connecting portion is fixedly connected to the inner side of the outer door panel through a sealant to form a water blocking structure; in the thickness of the car door, the cross-sectional shape of the first connecting portion is wavy; the second connecting portion has a concave portion, and the concave portion at least partially accommodates the end of the bumper beam, and the higher end of the bumper beam is connected to the concave portion; the fixing portion is fixed on the inner door panel; there is a gap between the higher end of the bumper beam and the fixing portion; the car door further includes a second mounting structure; the second mounting structure is connected to the lower end of the bumper beam and fixed on the inner door panel; the bumper beam is fixed on the inner door panel through the first mounting structure and the second mounting structure; the car door further includes a car door hinge, and the car door hinge is connected to the inner door panel and connected to the fixing portion.

[0030] As described above, by making the bumper beam an open tubular structure, the structure of the bumper beam can be simplified, the cost of the bumper beam can be reduced, and the weight of the car door can be reduced. In addition, by making the bumper beam open, it is also convenient for air to enter the interior of the bumper beam from the end, so that the interior of the bumper beam can be kept dry.

[0031] By arranging the anti-collision beam in an inclined manner, when water enters the anti-collision beam from the open end of the anti-collision beam, the water can flow out under the action of its own weight. Thus, rusting of the anti-collision beam can be avoided, thereby improving the structural strength of the anti-collision beam and driving safety.

[0032] By arranging the first mounting structure at the higher end of the anti-collision beam and making the first connecting portion gradually incline downward and inward towards the vehicle, an inclined waterproof structure can be formed above the higher end of the anti-collision beam by the first connecting portion. When the water entering the door falls, it can flow inward towards the vehicle under the guidance of the first connecting portion, so that the water flows past the anti-collision beam towards the inner position of the vehicle, avoiding the water from flowing into the anti-collision beam through the open end at the higher end of the anti-collision beam. Thus, water accumulation inside the anti-collision beam can be avoided, rusting of the anti-collision beam can be avoided, and the structural strength of the door and driving safety affected by the rusting of the anti-collision beam can also be avoided.

[0033] By making the first connecting portion wavy, when the first connecting portion guides the water, the path length of the water flow can be increased, the downward flow speed of the water can be reduced, the possibility of water droplets quickly impacting other components located below the anti-collision beam can be reduced, and the splashing water droplets generated after dripping on other components can also be reduced, thereby reducing the possibility of rusting and damage to other components inside the door.

[0034] By fixedly connecting the upper end of the first connecting portion to the outer door panel through sealant, the waterproof performance between the first connecting portion and the outer door panel can be improved, avoiding water flowing from the connection position between the first connecting portion and the outer door panel to the lower part of the first connecting portion, and further avoiding water flowing into the end of the anti-collision beam. Thus, the blocking effect on water can be improved, and water accumulation and rusting inside the anti-collision beam can be avoided. In addition, the first connecting portion and the outer door panel are connected through a seal, compared with the welding method, not only can the installation difficulty be reduced, but also the appearance of the outer door panel during the welding process can be avoided from being affected.

[0035] By providing a gap between the higher end of the anti-collision beam and the fixing portion, a gap can be formed between the higher end of the anti-collision beam and the inner door panel. Thus, water flowing down along the inner door panel can be prevented from flowing into the anti-collision beam through the higher end of the anti-collision beam, thereby improving the waterproof effect on the end of the anti-collision beam.

[0036] By fixing the anti-collision beam on the inner door panel through the first mounting structure and the second mounting structure, the stability and structural strength of the anti-collision beam can be improved.

[0037] By connecting the door hinge to the fixing part, the first installation structure can be reused, so that the first installation structure can be used to install the anti-collision beam while also being used to install the door hinge. Thus, there is no need to separately set up an installation structure specifically for installing the door hinge, which can reduce the number of parts of the door, lower the production cost, and simplify the installation steps.

[0038] The second aspect of the present application provides a vehicle, including: a vehicle body; and a door in the first aspect of the present application.

[0039] Thus, by providing a water-blocking structure at the end of the anti-collision beam, when water enters the door, the water can be blocked by the water-blocking structure, preventing the water from entering the anti-collision beam from the end of the anti-collision beam. Therefore, it is possible to avoid the accumulation of water inside the anti-collision beam, prevent the anti-collision beam from rusting, and also avoid affecting the door structure and driving safety due to the rusting of the anti-collision beam.

Additionally, in one or more embodiments, the various specific features, structures, or characteristics can be combined in any suitable manner, as will be apparent to those of ordinary skill in the art from this disclosure.

[0058] Next, with reference to the accompanying drawings, exemplary descriptions will be made of possible embodiments of the installation structure of the anti-collision beam 300 of the vehicle door 20 in the present application.

[0059] Figure 1 It is a schematic three-dimensional structure diagram of a partial structure of the vehicle door 20 in an embodiment of the present application; Figure 2 It is a schematic structural diagram of the connection between the first installation structure 400, the anti-collision beam 300, and the inner door panel 100 of the vehicle door 20; Figure 3 It is a schematic structural diagram of the connection between the first installation structure 400 and the inner door panel 100 of the vehicle door 20; Figure 4 It is another schematic structural diagram of the connection between the first installation structure 400, the anti-collision beam 300, and the inner door panel 100 of the vehicle door 20.

[0060] As Figures 1 - 4 shown, the vehicle door 20 in the present application includes an inner door panel 100 and an anti-collision beam 300. Among them, the anti-collision beam 300 is installed on the inner door panel 100.

[0061] In some embodiments, as Figure 1 shown, the end of the anti-collision beam 300 is an open structure. In this embodiment, the anti-collision beam 300 is a hollow tubular structure, which has high structural strength and can reduce the overall weight of the vehicle door 20. At the same time, setting the end of the anti-collision beam 300 as an open structure can also facilitate air to enter the inside of the anti-collision beam 300 from the end, which is beneficial to keeping the inside of the anti-collision beam 300 dry.

[0062] A water-blocking structure is provided at the end of the anti-collision beam 300. Thus, by providing a water-blocking structure at the end of the anti-collision beam 300, when water enters the vehicle door 20, the water can be blocked by the water-blocking structure, preventing the water from entering the anti-collision beam 300 from the end. Thereby, it is possible to avoid the accumulation of water inside the anti-collision beam 300, prevent the anti-collision beam 300 from rusting, and also avoid affecting the structure and driving safety of the vehicle door 20 due to the rusting of the anti-collision beam 300.

[0063] In some embodiments, the water blocking structure is connected to the inner door panel 100, and the anti-collision beam 300 is installed on the inner door panel 100 through the water blocking structure. Thus, the water blocking structure can be reused, and the anti-collision beam 300 is installed on the inner door panel 100 through the water blocking structure, thereby reducing the number of parts, the installation difficulty, and the cost of the door 20.

[0064] Figure 5 For Figure 1 Schematic diagram of the connection structure between the first installation structure 400, the outer door panel 200, and the anti-collision beam 300 in [the figure]. In some embodiments, as Figures 1 - 5 shown, the door 20 in the present application further includes an outer door panel 200 and a first installation structure 400. Among them, the outer door panel 200 is connected to the outer side of the inner door panel 100. The first installation structure 400 is connected to the end of the anti-collision beam 300, and the first installation structure 400 has a first connection portion 411, and the first connection portion 411 is fixedly connected to the outer door panel 200 to form a water blocking structure. Thus, the first installation structure 400 is connected to the outer door panel 200 through the first connection portion 411, so that the anti-collision beam 300 can be fixedly connected to the outer door panel 200. By making the first connection portion 411 form a water blocking structure, the first installation structure 400 can be reused. While the anti-collision beam 300 is fixed on the outer door panel 200 through the first installation structure 400, the first connection portion 411 forms a water blocking structure. After water enters the door 20, it is prevented from flowing into the anti-collision beam 300 from the end of the anti-collision beam 300. Thus, water accumulation inside the anti-collision beam 300 can be avoided, rusting of the anti-collision beam 300 can be avoided, and the influence of rusting of the anti-collision beam 300 on the structure of the door 20 and driving safety can also be avoided.

[0065] In some embodiments, as Figure 2 、 Figure 4 、 Figure 5 shown, the upper end of the first connection portion 411 is connected to the inner side of the outer door panel 200, and the first connection portion 411 is gradually inclined downward and inward in the direction of the vehicle 1. Thus, by making the first connection portion 411 gradually inclined downward and inward in the direction of the vehicle 1. As Figure 5 shown, the first connection portion 411 and the outer door panel 200 form a water blocking structure similar to a triangle, so that after water enters the door 20, the first connection portion 411 can guide the water to prevent the water from flowing into the anti-collision beam 300 from the end of the anti-collision beam 300.

[0066] In some embodiments, as Figure 5As shown, in the thickness direction of the vehicle door 20, the cross-sectional shape of the first connecting portion 411 is wavy. Thus, by making the first connecting portion 411 wavy, when the first connecting portion 411 guides water, the path length of water flow can be increased, the downward flow rate of water can be reduced, the possibility of water droplets rapidly impacting other components located below the anti-collision beam 300 can be reduced, and the splashing water droplets generated after dripping on other components can also be reduced, thereby reducing the possibility of rust and damage to other components inside the vehicle door 20.

[0067] In some embodiments, as Figure 5 shown, the upper end of the first connecting portion 411 is fixedly connected to the outer door panel 200 through a sealant 413, improving the waterproof performance between the first connecting portion 411 and the outer door panel 200, preventing water from flowing from the connection position between the first connecting portion 411 and the outer door panel 200 to the lower part of the first connecting portion 411, and further preventing water from flowing into the end of the anti-collision beam 300. Thus, the water blocking effect can be improved, and water accumulation and rusting inside the anti-collision beam 300 can be avoided. At the same time, connecting the outer door panel 200 with the sealant 413 can avoid affecting the appearance of the outer door panel caused by welding or other methods.

[0068] Figure 6 For Figure 1 one of the three-dimensional structure schematic diagrams of the first mounting structure 400; Figure 7 For Figure 1 two of the three-dimensional structure schematic diagrams of the first mounting structure 400; Figure 8 one of the mounting structure schematic diagrams of the first mounting structure 400 and the anti-collision beam 300; Figure 9 two of the mounting structure schematic diagrams of the first mounting structure 400 and the anti-collision beam 300. In some embodiments, as Figures 2 - 9 shown, the first mounting structure 400 further has a second connecting portion 412. The upper part of the second connecting portion 412 is connected to the lower part of the first connecting portion 411. The end of the anti-collision beam 300 is connected to the second connecting portion 412 and is located between the outer door panel 200 and the second connecting portion 412. Since the anti-collision beam 300 is a tubular structure, in order to facilitate matching with the shape of the anti-collision beam 300 for fixing the anti-collision beam 300, the second connecting portion 412 has a concave portion. The shape of the concave portion is arc-shaped, and at least part of the concave portion accommodates the end of the higher-position end of the anti-collision beam 300. Since the end of the anti-collision beam 300 is connected to the second connecting portion 412 and is located between the outer door panel 200 and the second connecting portion 412, the end of the anti-collision beam 300 can be located below the first connecting portion 411. Thus, when water enters the vehicle door 20 and flows downward, the first connecting portion 411 can guide the water, allowing the water to flow away from above the end of the anti-collision beam 300, and preventing water from flowing into the anti-collision beam 300 from the end of the anti-collision beam 300.

[0069] In some embodiments, in the plane where the inner door panel 100 is located, the projection of the outer edge of the end of the anti-collision beam 300 is located within the projection area of the first mounting structure 400. Thus, a gap can be formed between the end of the anti-collision beam 300 and the inner door panel 100. Thereby, it is possible to prevent water flowing down along the inner door panel 100 from flowing into the anti-collision beam 300 through the end of the anti-collision beam 300, thereby improving the waterproof effect on the end of the anti-collision beam 300.

[0070] In some embodiments, as Figures 2 - 4 , Figures 6 - 9 shown, the first mounting structure 400 further includes a fixing portion 420, and the fixing portion 420 is connected to the first connecting portion 411 and fixedly connected to the inner door panel 100.

[0071] In some embodiments, as Figures 2 - 4 , Figures 6 - 9 shown, the included angle between the first connecting portion 411 and the fixing portion 420 is set as α, and 0° ≤ α ≤ 180°. Preferably, α can be about 90°, for example, 80° ≤ α ≤ 100°. Since the thickness of the vehicle door 20 is limited, the gap between the inner door panel 100 and the outer door panel 200 is small. Generally, the inner door panel 100 of the vehicle door 20 will bend outward at the edge position of the vehicle door 20 and connect with the outer door panel 200. By setting the fixing portion 420 and the first connecting portion 411 at an included angle, the installation difficulty of the first mounting structure 400 can be reduced. Moreover, the bending of the fixing portion can also facilitate the connection with the vehicle door hinge 600.

[0072] Figure 10 For Figure 1 the schematic diagram of the connection between the first mounting structure 400 and the vehicle door hinge 600 in Figure 1 , Figure 10 shown, the first mounting structure 400 is a vehicle door hinge bracket. Thus, by making the first mounting structure 400 a vehicle door hinge bracket, the bracket for mounting the anti-collision beam 300 and the bracket for mounting the vehicle door hinge 600 can be integrated, thereby reducing the number of parts and the number of spot welds for fixing and mounting the brackets, and thus reducing the production cost.

[0073] In some embodiments, as Figure 1 , Figure 10As shown, the vehicle door 20 in the present application further includes a door hinge 600. The door hinge 600 is connected to the first mounting structure 400, and the door hinge 600 is located on the outer side of the door inner panel 100 close to the vehicle body 10. By mounting the door hinge 600 on the first mounting structure 400, the first mounting structure 400 can be reused to mount the door hinge 600, that is, the anti-collision beam 300 and the door hinge 600 can be mounted on the first mounting structure 400 simultaneously. Thus, it is not necessary to separately provide a mounting structure for mounting the door hinge 600, thereby reducing the number of parts of the vehicle door 20, reducing the weight and production cost of the vehicle door 20, and simplifying the installation steps.

[0074] In some embodiments, the door hinge 600 and the fixing portion 420 are connected through the door inner panel 100. Specifically, connecting members such as bolts and rivets are used to pass through the door hinge 600, the door inner panel 100, and the fixing portion 420 for fixed connection.

[0075] In some embodiments, the door hinge 600 and the first mounting structure 400 are located on the front side of the vehicle door 20 (assuming the forward direction of the vehicle 1 is the front), or the door hinge 600 and the first mounting structure 400 are located on the rear side of the vehicle door 20.

[0076] In other embodiments, if the door hinge 600 is not connected to the fixing portion 420, the fixing portion 420 can also be in the same plane as the first connecting portion 411, and the fixing portion 420 is fixed on the surface of the door inner panel 100 that is bent outward.

[0077] In some embodiments, as Figure 6 、 Figure 7 shown, the first mounting structure 400 is an integral part. The first mounting structure 400 further includes a connecting end 410, and the first connecting portion 411 and the second connecting portion 412 are provided on the connecting end 410; the connecting end 410 and the fixing portion 420 are arranged at an angle.

[0078] In some embodiments, as Figure 1 shown, the vehicle door 20 in the present application further includes a second mounting structure 500. One end of the anti-collision beam 300 away from the water blocking structure is fixed to the door inner panel 100 through the second mounting structure 500. By providing the second mounting structure 500, together with the first mounting structure 400, the anti-collision beam 300 can be fixed at both ends of the anti-collision beam 300. Thus, the stability and structural strength of the anti-collision beam 300 can be improved.

[0079] In some embodiments, as Figure 1As shown, the anti-collision beam 300 is inclined in the height direction of the vehicle door 20, and the water blocking structure is located at the higher end of the anti-collision beam 300. Thus, by arranging the water blocking structure at the higher end of the anti-collision beam 300, water can be prevented from entering the anti-collision beam 300 from the end of the anti-collision beam 300.

[0080] In some embodiments, as Figures 1 - 10 shown, the anti-collision beam 300 has an open tubular structure; in the height direction of the vehicle door 20, the anti-collision beam 300 is inclined; the vehicle door 20 further includes an outer door panel 200; the outer door panel 200 is connected to the outer side of the inner door panel 100; the vehicle door 20 further includes a first mounting structure 400; the first mounting structure 400 is located at the higher end of the anti-collision beam 300; the first mounting structure 400 has a first connecting portion 411, a second connecting portion 412, and a fixing portion 420; the lower part of the first connecting portion 411 is connected to the upper part of the second connecting portion 412, and the sides of the first connecting portion 411 and the second connecting portion 412 are connected to the fixing portion 420; the first connecting portion 411 is inclined downward and inward of the vehicle from top to bottom; the upper part of the first connecting portion 411 is fixedly connected to the inner side of the outer door panel 200 through a sealant 413 to form a water blocking structure; in the thickness direction of the vehicle door 20, the cross-sectional shape of the first connecting portion 411 is wavy; the second connecting portion 412 has a concave portion, and the concave portion at least partially accommodates the end of the anti-collision beam 300, and the higher end of the anti-collision beam 300 is connected to the concave portion; the fixing portion 420 is fixed to the inner door panel 100; there is a gap between the higher end of the anti-collision beam 300 and the fixing portion 420; the vehicle door 20 further includes a second mounting structure 500; the second mounting structure 500 is connected to the lower end of the anti-collision beam 300 and fixed to the inner door panel 100; the anti-collision beam 300 is fixed to the inner door panel 100 through the first mounting structure 400 and the second mounting structure 500; the vehicle door 20 further includes a vehicle door hinge 600, and the vehicle door hinge 600 is connected to the inner door panel 100 and connected to the fixing portion 420.

[0081] Thus, by making the anti-collision beam 300 have an open tubular structure, the structure of the anti-collision beam 300 can be simplified, the cost of the anti-collision beam 300 can be reduced, and the weight of the vehicle door 20 can be reduced. In addition, by making the anti-collision beam 300 have an open shape, air can also enter the interior of the anti-collision beam 300 from the end, keeping the interior of the anti-collision beam 300 dry.

[0082] By inclining the anti-collision beam 300, when water enters the anti-collision beam 300 from the open end of the anti-collision beam 300, the water can flow out under the action of its own weight. Thus, rusting of the anti-collision beam 300 can be avoided, thereby improving the structural strength of the anti-collision beam 300 and driving safety.

[0083] By arranging the first mounting structure 400 at the higher end of the bumper beam 300, the first connecting portion 411 is inclined downward and inward of the vehicle, so that an inclined waterproof structure can be formed above the higher end of the bumper beam 300 by the first connecting portion 411. When the water entering the door 20 falls, it can flow inward of the vehicle 1 under the guidance of the first connecting portion 411, so that the water flows from the bumper beam 300 toward the inner position of the vehicle 1, avoiding the water flowing into the bumper beam 300 from the open end at the higher end of the bumper beam 300. Thus, the accumulation of water inside the bumper beam 300 can be avoided, the rusting of the bumper beam 300 can be avoided, and the influence of the rusting of the bumper beam 300 on the structural strength of the door 20 and the driving safety can also be avoided.

[0084] By making the first connecting portion 411 wavy, when the first connecting portion 411 guides the water, the path length of the water flow can be increased, the downward flow rate of the water can be reduced, the possibility of the water droplets rapidly impacting other components located below the bumper beam 300 can be reduced, and the splashing water droplets generated after the water droplets fall on other components can also be reduced, thereby reducing the possibility of rusting and damage of other components inside the door 20.

[0085] By fixedly connecting the upper end of the first connecting portion 411 to the outer door panel 200 through the sealant 413, the waterproof performance between the first connecting portion 411 and the outer door panel 200 can be improved, avoiding the water flowing from the connection position between the first connecting portion 411 and the outer door panel 200 to the lower part of the first connecting portion 411, and further avoiding the water flowing into the end of the bumper beam 300. Thus, the blocking effect on the water can be improved, and the accumulation of water and rusting inside the bumper beam 300 can be avoided. In addition, the first connecting portion 411 and the outer door panel 200 are connected through the sealant 413. Compared with the welding method, not only can the installation difficulty be reduced, but also the influence on the appearance of the outer door panel 200 during the welding process can be avoided.

[0086] By providing a gap between the higher end of the bumper beam 300 and the fixing portion 420, a gap can be formed between the higher end of the bumper beam 300 and the inner door panel 100. Thus, the water flowing down along the inner door panel 100 can be prevented from flowing into the bumper beam 300 from the higher end of the bumper beam 300, thereby improving the waterproof effect on the end of the bumper beam 300.

[0087] By fixing the bumper beam 300 to the inner door panel 100 through the first mounting structure 400 and the second mounting structure 500, the stability and structural strength of the bumper beam 300 can be improved.

[0088] By connecting the door hinge 600 to the fixing part 420, the first mounting structure 400 can be reused, so that the first mounting structure 400 can be used to mount the anti-collision beam 300 and the door hinge 600 at the same time during installation and fixing. Therefore, there is no need to separately set up a mounting structure for specifically mounting the door hinge 600, thus reducing the number of parts of the door 20, lowering the production cost, and simplifying the installation steps.

[0089] The above content has given an exemplary description of possible embodiments of the mounting structure of the anti-collision beam 300 of the door 20. Next, with reference to the accompanying drawings, the specific structure of the vehicle 1 in the present application will be described in detail in a specific embodiment.

[0090] Figure 11 This is a schematic side view of the vehicle 1 in the embodiment of the present application. As Figure 11 shown, the vehicle 1 in the present application includes a vehicle body 10 and a door 20. Among them, the vehicle body 10 has a car body for accommodating drivers and passengers, and the door 20 is hinged to the vehicle body 10 at its front side position for opening and closing the car body.

[0091] As Figures 1 - 10 shown, the door 20 includes an inner door panel 100, an outer door panel 200, an anti-collision beam 300, a first mounting structure 400, a second mounting structure 500, and a door hinge 600 (the illustrated structure is a part of the door hinge). Among them, the inner door panel 100 is located inside the door 20, and the outer door panel 200 is located outside the door 20. An accommodation space for accommodating the anti-collision beam 300, the first mounting structure 400, and the second mounting structure 500 is formed between the inner door panel 100 and the outer door panel 200.

[0092] As Figure 1 shown, the anti-collision beam 300 is a circular tubular member with openings at both ends, and is arranged in the accommodation space of the door 20 in the front-rear direction. The front end of the anti-collision beam 300 is fixed to the inner door panel 100 through the first mounting structure 400, and the rear end of the anti-collision beam 300 is fixed to the inner door panel 100 through the second mounting structure 500.

[0093] In addition, as Figure 1 shown, in this embodiment, the front end of the anti-collision beam 300 is slightly higher than the rear end, and the anti-collision beam 300 is arranged obliquely up and down.

[0094] As Figures 6 - 10 shown, the first mounting structure 400 is an integral part made of sheet metal, and includes a connection end 410 and a fixing part 420. Among them, a first connection part 411 and a second connection part 412 are provided on the connection end 410.

[0095] As Figures 3 - 10As shown, the first connecting portion 411 is disposed above the second connecting portion 412, and the upper end of the first connecting portion 411 inclines toward the outside of the vehicle door 20. Thus, the first connecting portion 411 can be disposed above the front end of the anti-collision beam 300 in an inclined manner up and down, and a water-blocking structure is formed. When water enters the accommodation space of the vehicle door 20, the first connecting portion 411 can guide the water, and guide the water above the front end of the anti-collision beam 300 to the inner door panel 100 side, avoiding water from falling into the opening at the front end of the anti-collision beam 300.

[0096] As Figure 5 shown, the upper end of the first connecting portion 411 is fixedly connected to the outer door panel 200 through a sealant 413, avoiding using a welding connection method that may affect the appearance of the outer door panel 200. The first connecting portion 411 and the outer door panel 200 form a triangular structure. Thus, the front end of the anti-collision beam 300 can be completely blocked below, avoiding water entering the accommodation space from flowing along the outer door panel 200 into the opening at the front end of the anti-collision beam 300.

[0097] As Figure 5 shown, the first connecting portion 411 is wavy from top to bottom, so that when water flows downward along the first connecting portion 411, the flow rate of the water can be slowed down. Thus, the speed of the water can be reduced, and further the water droplets splashed when the water drips downward can be reduced, thereby reducing the possibility of rust and damage to other components inside the vehicle door 20.

[0098] The second connecting portion 412 has a concave portion, and at least part of the concave portion accommodates the end of the anti-collision beam 300, and the higher end of the anti-collision beam 300 is connected to the concave portion. Specifically, due to the concave portion, the overall structure of the second connecting portion 412 is in a through-groove shape, and the front end of the anti-collision beam 300 is installed inside the second connecting portion 412 and fits with the arc-shaped inner wall of the groove, and is fixedly connected by welding.

[0099] As Figures 2 - 4 shown, the inner door panel 100 bends outward at the front side edge position of the vehicle door 20 and is connected to the outer door panel 200, and the vehicle door hinge 600 is located at the front side end face position of the vehicle door 20. As Figures 2 - 4 、 Figures 6 - 10 shown, the fixing portion 420 and the connecting end 410 are disposed at an angle. Specifically, it can be Figure 6 、 Figure 7 shown as a 90° angle. A plurality of mounting holes 421 are provided on the fixing portion 420, and connecting components such as bolts and rivets can pass through the mounting holes 421 on the fixing portion 420 and be fixedly connected to the inner door panel 100 and the vehicle door hinge 600. Thus, the vehicle door hinge 600 is fixed. That is to say, the first mounting structure 400 in this embodiment is a vehicle door hinge bracket. In addition, the vehicle door 20 has two hinges, upper and lower, as Figure 1As shown, in this embodiment, the first mounting structure 400 is the bracket of the lower door hinge 600.

[0100] In this embodiment, the anti-collision beam 300 is mounted using the door hinge bracket, eliminating the need to separately provide a bracket for mounting the anti-collision beam 300, which can reduce the number of components and the number of weld points.

[0101] At this time, considering requirements such as meeting test requirements, the vertical position of the first mounting bracket 400 cannot be too high, resulting in a relatively small upward and downward inclination angle of the anti-collision beam 300, making it prone to water accumulation and rusting after water ingress. Additionally, in actual applications, the middle part of the anti-collision beam 300 may bend downward, also causing water accumulation inside the anti-collision beam 300 and leading to rusting. Therefore, in this embodiment, a water-blocking structure is provided above the end of the anti-collision beam 300, which can prevent water from entering the end of the anti-collision beam 300 and reliably prevent rusting caused by water accumulation inside the anti-collision beam 300.

[0102] As Figure 1 、 Figure 8 shown, in the front-back direction, which is the orientation of the end of the anti-collision beam 300, there is a gap between the end of the anti-collision beam 300 and the fixing part 420. In the plane of the inner door panel 100, the projection of the outer edge of the end of the anti-collision beam 300 is located within the projection area of the first mounting structure 400. Thus, after the fixing part 420 is fixedly connected to the inner door panel 100, a gap can be formed between the end of the anti-collision beam 300 and the inner door panel 100. This can prevent water flowing down along the inner door panel 100 from flowing into the anti-collision beam 300 through the end of the anti-collision beam 300, thereby improving the waterproof effect at the end of the anti-collision beam 300.

[0103] Note that the above is only the preferred embodiment of the present application and the technical principles applied. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described here, and various obvious changes, re-adjustments, and substitutions can be made by those skilled in the art without departing from the protection scope of the present invention. Therefore, although the present application has been described in detail through the above embodiments, the present invention is not limited to the above embodiments. Without departing from the concept of the present invention, it can also include more other equivalent embodiments, all of which fall within the protection scope of the present invention.
