The embodiments described below by reference to the drawings are exemplary and are intended to explain the disclosure, and should not be understood as limiting the disclosure.

[0035] It should be noted that the "multiple" mentioned in the present document refers to two or more than two. The "and / or" describes the association relationship of the associated objects, which means that there can be three relationships, for example, A and / or B can represent the three cases of A alone, A and B together, and B alone. The character " / " generally represents that the front and rear associated objects are in an "or" relationship.

[0036] In one aspect of the present application, a vehicle is provided, which comprises a vehicle body 10 and a vehicle rocker assembly 30. The vehicle body 10 comprises a door frame 20. The vehicle rocker assembly 30 comprises an upper surrounding plate 100, a side surrounding plate 200 and a reinforcing beam 300 arranged at the bottom of the door frame 20, which can strengthen the bottom of the door frame 20 and form an electrophoresis cavity that increases the electrophoresis effect.

[0037] Referring to Figure 1 The vehicle further comprises a vehicle body 10, which comprises a front door frame and a rear door frame. The reinforcing beam 300 of the vehicle rocker assembly 30 is arranged in the front door frame and the rear door frame at the same time, so that the reinforcing beam 300 between the front door frame and the rear door frame is an integral structure, thereby increasing the structural strength of the vehicle body 10. The upper surrounding plate 100 comprises two, which are a first upper surrounding plate and a second upper surrounding plate. The first upper surrounding plate and the second upper surrounding plate are arranged at the front door frame and the rear door frame respectively. Since the B pillar 12 is arranged between the front door frame and the rear door frame, the vehicle rocker assembly 30 is facilitated to be assembled in the front door frame and the rear door frame.

[0038] Referring to Figure 2 The vehicle body 10 further comprises an A pillar 11 and the above-mentioned B pillar 12. The A pillar 11 is arranged on the side of the front door frame away from the rear door frame, and the B pillar 12 is arranged between the front door frame and the rear door frame. The A pillar 11 comprises an A pillar lower inner plate 710, and the B pillar 12 comprises a B pillar lower inner plate 720. The A pillar lower inner plate 710 is connected to the first upper surrounding plate, and the B pillar lower inner plate 720 is connected to the first upper surrounding plate and the second upper surrounding plate. The A pillar lower inner plate 710, the first upper surrounding plate, the B pillar lower inner plate 720 and the second upper surrounding plate are connected in sequence, thereby increasing the integrity and structural strength of the inside of the vehicle body 10.

[0039] In the embodiment, the vehicle body 10 further comprises a C pillar 13. Since the side surrounding assembly arranged in the A pillar 11, the B pillar 12 and the C pillar 13 has a high assembly difficulty, the side surrounding assembly between the A pillar 11, the B pillar 12 and the C pillar 13 is designed in sections by arranging the upper surrounding plate 100. At the same time, the side surrounding assembly of the A pillar 11, the B pillar 12 and the C pillar 13 is welded with the upper surrounding plate 100, thereby reducing the assembly difficulty and the cost.

[0040] In the embodiment, the side surrounding assembly is arranged on the outside of the rocker beam and is welded by a side surrounding framework and a side surrounding outer plate. The lower part of the side surrounding assembly is fixedly connected with the outside vertical surface of the rocker beam by FDS nails, but it is not limited to using FDS nails.

[0041] More specifically, in one embodiment, combined with Figure 4 and Figure 5 As shown, the reinforcing beam 300 includes an outer wall 320, a top wall 310, and an inclined wall 330 connecting the side walls and the top wall 310. A side panel 200 connects the outer wall 320 and the upper panel 100, and the upper panel 100 connects the top wall 310. The side panel 200, the upper panel 100, and the inclined wall 330 together form a threshold cavity 400. Due to the inclined wall 330, the space and area of ​​the threshold cavity 400 are increased, thereby improving the area and time of electrophoretic fluid flow within the threshold cavity 400.

[0042] In this embodiment, the side wall of the reinforcing beam 300 facing the top of the vehicle body 10 is the top wall 310, and the side wall of the reinforcing beam 300 facing the outside of the vehicle is the outer wall 320.

[0043] Reference Figure 1 As shown, the door opening 21 is a spatial structure formed by the door frame 20. The door opening stop is located at the bottom of the door opening 21 and is the door stopping structure. The door sill assembly 30 is located at the bottom of the door frame 20 and is one of the important components of the door opening stop. It can prevent the door from being closed too much and make the outer surface of the door flush with the outer surface of the vehicle body 10.

[0044] Combination Figure 4 and Figure 5 As shown, the upper enclosure 100 is fitted and connected to the top wall 310, and the side enclosure 200 is spaced apart from the inclined wall 330 and part of the outer wall 320. When the electrophoretic liquid is introduced into the sill cavity 400, the electrophoretic liquid can flow through the inclined wall 330. When the electrophoretic liquid flows in the sill cavity 400, the electrophoretic area of ​​the reinforcing beam 300 can be increased to a greater extent.

[0045] Reference Figure 4 As shown, the upper panel 100 is provided with locking holes 124, and the upper panel 100 and the reinforcing beam 300 are locked together by locking components. Specifically, FDS nails are used for locking, but it is not limited to the use of FDS nails.

[0046] Reference Figure 5 As shown, the reinforcing beam 300 is made of aluminum alloy and is formed using an extrusion process. Specifically, the reinforcing beam 300 has a hollow internal structure, meaning a cavity 340 is formed inside the reinforcing beam 300, ensuring both structural integrity and lightweight design. Furthermore, the aluminum alloy reinforcing beam 300 possesses excellent corrosion resistance. More specifically, the hollow structure is equipped with cross-arranged reinforcing ribs 350, which subdivide the hollow structure 340 into at least two sub-cavities. These include two upper sub-cavities, one located below the inclined wall 330, and the other below the top wall 310. Additional sub-cavities may be included depending on actual needs to further reduce the weight of the reinforcing beam 300.

[0047] In this embodiment, each door frame 20 on the vehicle body 10 is provided with the above-mentioned rocker assembly. When the vehicle body 10 is electrophoresed, it is immersed in an electrophoresis tank, and then electrophoresis is carried out after power is turned on. At the rocker assembly, the electrophoresis liquid can enter the rocker cavity 400, and the inner wall of the side wall 200, the inner wall of the upper wall 100 and the inclined wall 330 in the rocker cavity 400 can be submerged and electrophoresed by the electrophoresis liquid, so as to improve the electrophoresis effect.

[0048] Referring to Figure 4 As shown in the figure, the upper wall 100 is provided with a first flow-through hole 410, which is in communication with the rocker cavity 400. The first flow-through hole 410 penetrates the upper wall 100 and faces the door opening 21 direction. The electrophoresis liquid can enter the rocker cavity 400 through the first flow-through hole 410.

[0049] Referring to Figure 6 As shown in the figure, the upper wall 100 includes a first connecting portion 110 and a second connecting portion 120. The second connecting portion 120 is formed by bending and extending from the first connecting portion 110. The first connecting portion 110 connects the top wall 310, and the second connecting portion 120 connects the side wall 200. The first flow-through hole 410 is arranged at the position where the second connecting portion 120 connects the first connecting portion 110, and the first flow-through hole 410 communicates with the rocker cavity 400. During electrophoresis, the electrophoresis liquid can enter the rocker cavity 400 through the first flow-through hole 410.

[0050] Specifically, the second connecting portion 120 and the side wall 200 are connected by welding, and can also be connected by FDS nails, but are not limited to using FDS nails.

[0051] Referring to Figure 4 As shown in the figure, the second connecting portion 120 includes a fixed segment 121 and a transition segment 122. The transition segment 122 is formed by the inclined extension of the first connecting portion 110. The fixed segment 121 is fixed to the top wall 310. The first flow-through hole 410 is arranged on the transition segment 122. The transition segment 122 is an inclined structure between the fixed segment 121 and the first connecting portion 110. The first flow-through hole 410 arranged on the transition segment 122 can reduce the process difficulty. The transition segment 122 is provided with a boss 123 between two adjacent first flow-through holes 410, which can ensure the electrophoresis effect and enhance the strength of the transition segment 122.

[0052] Referring to Figure 4 and Figure 6 As shown in the figure, the first flow-through hole 410 is a strip-shaped hole, which can increase the opening area to ensure the flow rate of the electrophoresis liquid.

[0053] Referring to Figure 6As shown, the boss 123 protrudes towards the doorway 21. The boss 123 has a circular hole 1231, which can serve as an inlet for the electrophoretic solution and also provide space for wax injection in subsequent processes. The circular hole 1231 is sealed with a patch to prevent water from entering the sill cavity 400 through the circular hole 1231 during vehicle use, thus avoiding corrosion of the sidewall of the sill cavity 400. In other embodiments, the circular hole 1231 can also be directly provided on the transition section 122.

[0054] Reference Figure 7 As shown, the second connecting part 120 includes an abutting part 125 and a protrusion part 126. The abutting part 125 is connected to the side panel 200. The protrusion part 126 protrudes away from the side panel 200 and is spaced apart from the side panel 200 to form a second flow hole 420. The first flow hole 410, the threshold cavity 400, and the second flow hole 420 are interconnected. When electrophoretic liquid enters the threshold cavity 400, the electrophoretic liquid can enter the threshold cavity 400 from the first flow hole 410 and the second flow hole 420, increasing the inflow of electrophoretic liquid.

[0055] Reference Figure 3 and Figure 8 As shown, the side panel 200 has a raised rib 210 away from the outer wall 320. The raised rib 210 and the outer wall 320 are spaced apart between the inner wall and the outer wall 320 of the side panel 200 to form a third flow hole 430. The third flow hole 430 is connected to the sill cavity 400. The third flow hole 430 can enter the electrophoretic liquid from below the vehicle body 10, and after electrophoresis is completed, most of the electrophoretic liquid can be discharged from the sill cavity 400 through the third flow hole 430.

[0056] In some specific embodiments, there are multiple ribs 210, which are spaced apart. The multiple ribs 210 are arranged along the direction of the reinforcing beam 300. The ribs 210 are simultaneously provided on both the front and rear door frames. During electrophoresis, they are used to prevent liquid leakage at the bottom of the door frame 20, increasing the flow area of ​​the electrophoretic solution in the door frame 20 to enhance the electrophoresis effect.

[0057] In this embodiment, during electrophoresis of the vehicle body 10, the vehicle body 10 is immersed in the electrophoresis solution. The electrophoresis solution enters the sill cavity 400 through the first flow hole 410, the second flow hole 420, and the third flow hole 430. Air in the sill cavity 400 is randomly discharged through the first flow hole 410, the second flow hole 420, or the third flow hole 430. After electrophoresis is completed, the vehicle body 10 is removed from the electrophoresis solution, and the electrophoresis solution flows out again through the first flow hole 410, the second flow hole 420, or the third flow hole 430. This avoids the negative pressure formed in the sill cavity 400 from preventing the electrophoresis solution from entering the sill cavity 400, and also prevents the accumulation of electrophoresis solution in the sill cavity 400.

[0058] Reference Figure 2 and Figure 4As shown, the vehicle rocker assembly 30 further comprises a rocker trim panel 500 and a wire harness assembly 600, the rocker trim panel 500 is connected to the outer body 10, and the rocker trim panel 500 covers the upper apron 100 and forms a receiving cavity 520 between the rocker trim panel 500 and the upper apron 100, and the wire harness assembly 600 is arranged in the receiving cavity 520, which can hide the wire harness and make the structure of the vehicle more compact.

[0059] Referring to Figure 3 and Figure 4 As shown, the rocker trim panel 500 is arranged above the upper apron 100, and a connecting bracket 510 is arranged between the rocker trim panel 500 and the upper apron 100 to connect the rocker trim panel 500 and the upper apron 100.

[0060] Specifically, the connecting bracket 510 is arranged on the first connecting portion 110 of the upper apron 100 and protrudes towards the door frame, and a plurality of connecting brackets 510 are arranged at intervals, and a first locking hole (not shown) is arranged on the connecting bracket 510, and the rocker trim panel 500 and the upper apron 100 are locked by the locking member in the first locking hole.
