[0032] Reference below Figure 1-Figure 4 A bolt 200 , a vehicle door 100 , and a vehicle 1000 according to an embodiment of the present invention are described.

[0033] like Figure 1-Figure 3 As shown, the bolt 200 according to the embodiment of the utility model includes: a screw rod 10 and a limiting head 20.

[0034] The screw rod 10 has a first end and a second end in the axial direction. The limit head 20 is arranged at the first end. The limit head 20 is provided with a drainage groove 23 extending in the radial direction. The drainage groove 23 is located on the side of the limit head 20 facing the second end.

[0035] It should be noted that after the limit head 20 is set at the first end of the screw 10, the drainage groove 23 thereon will face the second end on the limit head 20, and the drainage groove 23 will extend radially on the limit head 20, so that after the bolt 200 is assembled in the mounting hole of the side panel 1001 assembly, a cavity will be formed between the limit head 20 and the screw 10, so that when the entire vehicle body enters the electrophoretic tank, the electrophoretic liquid will enter the cavity, and at the same time, when the drainage groove 23 is set at the limit head 20, the cavity can be connected with the outside world, so that the electrophoretic liquid entering the cavity can be discharged through the drainage groove 23, so that the vehicle body is not prone to electrophoretic flow marks in the subsequent process flow, thereby reducing the grinding process, which can improve the production rhythm of the vehicle 1000.

[0036] According to the bolt 200 of the embodiment of the utility model, after the bolt 200 is assembled, the drainage groove 23 arranged on the limit head 20 can connect the cavity formed at the connection with the outside world, so that the electrophoretic liquid in the cavity can be discharged through the drainage groove 23, so that it is not easy to have electrophoretic flow marks on the vehicle body in the subsequent process flow, which can reduce the grinding process and thus improve the production rhythm.

[0037] In some embodiments, Figure 1-Figure 3 As shown, the limiting head 20 includes a limiting portion 22 and a tightening portion 21 , the tightening portion 21 is connected to the first end, the limiting portion 22 is located at the outer periphery of the tightening portion 21 , and the drainage groove 23 is formed in the limiting portion 22 .

[0038] It should be noted that after the tightening part 21 is connected to the first end, the screw rod 10 can be driven to rotate by controlling the rotation of the tightening part 21, so that the installation of the bolt 200 can be achieved. At the same time, a limiting part 22 is also provided, and the limiting part 22 is located on the outer periphery of the tightening part 21. In this way, when the bolt 200 is installed in place, the limiting part 22 will be against the installation surface, thereby ensuring the installation effect of the bolt 200, and the drainage groove 23 is formed in the limiting part 22, so that the cavity formed by the bolt 200 after the installation is completed can be connected with the outside through the drainage groove 23, so that the electrophoretic liquid in the cavity can be discharged through the drainage groove 23.

[0039] Among them, the limiting portion 22 located on the outer periphery of the tightening portion 21 can be against the mounting surface when the bolt 200 is installed in place, so that the bolt 200 will not be installed excessively and cause the limiting head 20 and the screw rod 10 to be disconnected. At the same time, the drainage groove 23 is formed on the limiting portion 22. When the limiting portion 22 is against the mounting surface, the drainage groove 23 can form a drainage channel with the mounting surface, so that the electrophoretic liquid in the cavity can be discharged through the drainage channel.

[0040] Therefore, the tightening portion 21 of the limit head 20 can assist in the assembly of the bolt 200, and the limit portion 22 is located at the outer periphery of the tightening portion 21, so that when the bolt 200 is installed in place, the limit portion 22 can limit the bolt 200, so that the bolt 200 can have a better fixing effect, and the drainage groove 23 is formed on the limit portion 22, so that the drainage groove 23 can connect the cavity formed by the installation of the bolt 200 with the outside world, so that the electrophoretic liquid in the cavity can be discharged through the drainage groove 23.

[0041] In some embodiments, Figure 1-Figure 3 As shown, there are a plurality of drainage grooves 23 , and the plurality of drainage grooves 23 are distributed on the limiting portion 22 at intervals along the circumferential direction.

[0042] It should be noted that a plurality of drainage grooves 23 are arranged on the limit head 20, which can make the drainage efficiency of the drainage grooves 23 higher, so that the electrophoretic liquid in the cavity can be discharged faster, thereby avoiding the occurrence of electrophoretic flow marks in the subsequent process flow, which is not easy to affect the quality of the vehicle 1000. At the same time, when the plurality of drainage grooves 23 are distributed in the limit portion 22, they are distributed in a circumferential direction. In this way, the plurality of drainage grooves 23 can more effectively discharge the electrophoretic liquid, that is, when the assembly portion is at various angles, the drainage grooves 23 can have a drainage effect.

[0043] Therefore, by distributing the plurality of drainage grooves 23 at intervals in the circumferential direction on the limiting portion 22 , the electrophoretic liquid in the cavity can be discharged more easily and efficiently through the drainage grooves 23 .

[0044] In some embodiments, Figure 1-Figure 3 As shown, the limiting portions 22 of the plurality of drainage grooves 23 are arranged at equal angles.

[0045] It should be noted that the multiple drainage grooves 23 are arranged at equal angles so that they are more evenly distributed when set in the limiting portion 22, so that the bolt 200 can discharge the electrophoretic liquid in the cavity at any angle, thereby ensuring that the electrophoretic liquid in the cavity can be discharged, which will not affect the subsequent process flow.

[0046] For example, in this embodiment, three drainage grooves 23 can be provided, and each of the three drainage grooves 23 is distributed in the circumferential direction of the limiting portion 22 at an angle of 120°. In this way, no matter what angle the bolt 200 is at, there is a drainage groove 23 to discharge the electrophoretic liquid in the cavity, so that electrophoretic flow marks are less likely to occur in the subsequent process flow.

[0047] Therefore, multiple drainage grooves 23 can enable the electrophoretic liquid to be discharged from the cavity faster, and multiple drainage grooves 23 are arranged at equal angles, which can ensure that the drainage grooves 23 can be used for drainage when the bolt 200 is at any angle, thereby ensuring the overall drainage effect of the bolt 200, thereby avoiding the occurrence of electrophoretic flow marks in subsequent process flows.

[0048] In some embodiments, Figure 1-Figure 3 As shown, the limiting portion 22 is configured as a frustum, and the surface of the limiting portion 22 facing the second end is flush with the surface of the tightening portion 21 facing the second end.

[0049] It should be noted that the limiting portion 22 is constructed as a cone, which can reduce the electrophoretic fluid residue on the surface of the limiting portion 22, that is, when the electrophoretic fluid is attached to the cone, it can flow down along the inclined surface of the cone and will not remain on the cone. At the same time, the surface of the limiting portion 22 facing the second end is flush with the surface of the tightening portion 21 facing the second section, so that the limiting portion will not affect the installation of the bolt 200. At the same time, the tightening portion 21 can also assist the limiting portion 22 in limiting.

[0050] Furthermore, the limiting portion 22 is constructed as a cone, and the lower surface of the cone is the surface of the limiting portion 22 facing the second end, and the area of ​​the lower surface is larger than the area of ​​the upper surface, so that the electrophoretic liquid flowing down from the cone can be mixed with the electrophoretic liquid discharged from the drain groove 23. At the same time, the larger lower surface of the cone can ensure the limiting effect of the limiting portion 22.

[0051] Therefore, the limiting portion 22 is constructed as a cone so that the electrophoretic liquid attached to the limiting portion 22 can flow down more easily, thereby reducing the residual electrophoretic liquid on the surface of the limiting portion 22. At the same time, the surface of the limiting portion 22 facing the second end is flush with the surface of the tightening portion 21 facing the second end, so that the limiting portion 22 will not affect the installation of the bolt 200. At the same time, when the limiting portion 22 is limiting, the surface of the tightening portion 21 facing the second end can assist the limiting portion 22 in limiting.

[0052] In some embodiments, Figure 1-Figure 3 As shown, the drainage groove 23 is formed as an arc-shaped groove.

[0053] It should be noted that the drainage groove 23 constructed as an arc-shaped groove can make the limiting portion 22 of the bolt 200 easier to process. At the same time, after the drainage groove 23 is formed into an arc-shaped groove, the mounting surface that abuts against the bolt 200 after installation can define a drainage channel so that the electrophoretic liquid in the cavity can be discharged from the drainage channel.

[0054] Therefore, the liquid drain groove 23 is formed into an arc-shaped groove, which can make it easier to process the limiting portion 22 and also make it easier for the electrophoresis liquid to be discharged through the liquid drain groove 23 .

[0055] In some embodiments, the radial inner end opening size of the arc-shaped groove is smaller than the radial outer end opening size, and the opening size gradually increases from the inside to the outside.

[0056] It should be noted that the inner opening size of the arc-shaped groove is smaller than the outer opening size, so that when the electrophoretic liquid is discharged from the cavity, it will first pass through the smaller inner opening, and the opening size of the arc-shaped groove gradually increases from the inside to the outside, so that the electrophoretic liquid can be more easily discharged through the outer opening after entering the arc-shaped groove, thereby enabling the electrophoretic liquid to be more easily discharged from the cavity.

[0057] Therefore, the radial inner opening size of the arc-shaped groove is smaller than the radial outer opening size, and the opening size gradually increases from the inside to the outside, which can make the electrophoretic liquid in the cavity more easily discharged, thereby avoiding the occurrence of electrophoretic flow marks in subsequent process flows.

[0058] The utility model also provides a vehicle door 100 .

[0059] like Figure 4 As shown, the vehicle door 100 according to the embodiment of the utility model comprises: a vehicle door 100 body, on which a vehicle door 100 hinge is arranged; and a bolt 200 of any one of the above embodiments, wherein the bolt 200 is suitable for fixing the hinge assembly 101 to the vehicle body.

[0060] It should be noted that the bolt 200 fixes the hinge assembly 101 to the vehicle body, so that the door 100 body can be connected to the vehicle body through the door 100 hinge, and at the same time, the cavity formed by the bolt 200 after fixing the hinge assembly 101 can be connected to the outside through the drainage groove 23 on the bolt 200, so that the electrophoretic liquid entering the cavity can be discharged through the drainage groove 23, so that the electrophoretic liquid will not seep out from the connection during the subsequent processing of the vehicle body, resulting in an unfinished paint surface.

[0061] According to the vehicle door 100 of the embodiment of the utility model, the bolt 200 fixes the hinge assembly 101 to the vehicle body so that the vehicle door 100 body can be connected to the vehicle body, and at the same time, the drainage groove 23 on the bolt 200 can be connected to the cavity formed at the installation location so that the electrophoretic liquid in the cavity can be discharged from the cavity, thereby not affecting subsequent production.

[0062] The utility model also provides a vehicle 1000 .

[0063] like Figure 4-Figure 5 As shown, a vehicle 1000 according to an embodiment of the present utility model comprises: a door 100 of the above embodiment; and a vehicle body, wherein the door 100 is connected to a side wall 1001 of the vehicle body via a door 100 hinge.

[0064] It should be noted that the door 100 is connected to the side panel 1001 of the vehicle body through the door 100 hinge, so that the side panel 1001 will be sandwiched between the bolt 200 and the hinge assembly 101, and the limiting portion 22 of the bolt 200 will abut against the side panel 1001, and the limiting portion 22, the side panel 1001 and the screw 10 together define a cavity, so that after the vehicle body enters the electrophoretic tank, the electrophoretic liquid will enter the cavity, and the drainage groove 23 of the bolt 200 will be connected to the cavity, so that after the vehicle body leaves the electrophoretic tank, the electrophoretic liquid in the cavity will be discharged through the drainage groove 23, so that the vehicle body is not prone to electrophoretic flow marks in the subsequent process flow, thereby reducing the polishing process, which can improve the production cycle.

[0065] Therefore, the drain groove 23 on the bolt 200 can discharge the electrophoretic liquid in the cavity to avoid electrophoretic flow marks on the vehicle body in the subsequent process flow, which can reduce the grinding process and improve the production cycle.

[0066] In some embodiments, Figure 4 As shown, it also includes a hinge reinforcement plate 1002, which is located on the side of the side panel 1001 away from the hinge of the vehicle door 100. The hinge reinforcement plate 1002 and the drainage groove 23 define a drainage channel, and the drainage channel is connected to the cavity formed by the hinge reinforcement plate 1002 and the installation holes of the side panel.

[0067] It should be noted that the hinge reinforcement plate 1002 will abut against the limiting portion 22 of the bolt 200, so that the hinge reinforcement plate 1002 and the drainage groove 23 can define a drainage channel, and the drainage channel will be connected to the cavity, so that the electrophoretic liquid in the cavity can be discharged through the drainage channel, thereby making it less likely for the car body to have electrophoretic flow marks in subsequent process flows, thereby reducing the polishing process, which can improve the production cycle.

[0068] Therefore, after the bolt 200 is assembled, the drainage groove 23 and the hinge reinforcement plate 1002 define a drainage channel, and the drainage channel can connect the cavity with the outside world, so that the electrophoretic liquid in the cavity can be discharged through the drainage channel, so that it is not easy to have electrophoretic flow marks on the car body in the subsequent process flow, which can reduce the polishing process and thus improve the production cycle.
