Description

Technical Field

[0001] This utility model relates to the field of car door electrophoresis technology, and in particular to a flow guiding device for car door electrophoresis. Background Technology

[0002] In automotive painting processes, electrophoresis plays a crucial role in subsequent corrosion prevention, providing long-lasting rust protection during user operation. The body-in-white, after welding, undergoes cleaning, soaking, phosphating, electrophoresis, and rinsing before painting, effectively removing all surface oil. However, due to the body structure, welding edge adhesive, or pre-treatment electrophoresis parameters and spray pressure, a mixture of oil, degreasing solution, phosphating solution, and electrophoresis solution may remain in the body edges or cavities due to surface tension. This mixture is particularly problematic in edge seams, where it cannot drain completely and is difficult to remove even after electrophoresis and subsequent washing. Furthermore, the increased body temperature after electrophoresis causes the liquid in the edge seams to boil rapidly, overflowing from both inside and outside the seams, resulting in electrophoresis flow marks.

[0003] Channel flow marks refer to flow marks that do not originate at the initial site of the flow. They often occur through concealed internal channels, flowing downstream or dripping onto the exterior surface of the vehicle. These commonly occur in internal channels of door and window frames, door sills, and door latches. Because of their concealed nature, the source of these flow marks is difficult to locate. Disassembly is often required to analyze the liquid flow path and find the source for cleaning, which is a challenging and time-consuming process. Utility Model Content

[0029] Please see Figure 1 and Figure 2 This utility model provides a flow guiding device for electrophoresis on car doors, including a mounting base 1 and a fixing component 2. The mounting base 1 has a concave arc surface that fits against the folded edge of the car door, and a flow guiding groove 3 for temporary electrophoresis is provided on the mounting base 1. The opening of the flow guiding groove 3 abuts against the car door. The fixing component 2 is fixedly mounted on the mounting base 1 and has a protrusion for fixing to the process hole of the car door. The mounting base 1 is connected to the car door through the protrusion. The structure is simple and easy to install and disassemble. When electrophoresis is performed on the folded edge of the car door, the electrophoretic liquid flows into the flow guiding groove 3 and will not accumulate at the folded edge of the car door, eliminating the need for manual grinding of the folded edge of the car door and improving work efficiency.

[0030] Specifically, in an optional embodiment of this application, the fixing component 2 includes an adjusting rod 21, with protrusions at both ends of the adjusting rod 21. Both ends of the adjusting rod 21 are bent toward the door direction, and the bending of both ends of the adjusting rod 21 so that both ends are toward the door process hole, making it easier to fix the protrusions into the process hole.

[0031] Please see Figure 2 Specifically, in an optional embodiment of this application, a baffle 4 is provided on the mounting base 1. The baffle 4 is bent around the mounting base 1 to form the guide groove 3. Both ends of the baffle 4 abut against the car door. The baffle 4 is bent twice to form a C-shaped structure. The opening of the baffle 4 abuts against the folded edge of the car door to form a sealing structure.

[0032] Please see Figure 3Specifically, in an optional embodiment of this application, the top surface of the mounting base 1 is recessed downward to form the guide groove 3, and the depth of the guide groove 3 gradually increases along the direction away from the car door. The upper surface of the guide groove 3 forms an inclined guide surface, which makes it easier for the electrophoretic liquid to flow and avoids the electrophoretic liquid from being in contact with the folded edge of the car door for a long time.

[0033] Specifically, in an optional embodiment of this application, the fixing component 2 further includes a first fixing member 22 and a second fixing member 23. The first fixing member 22 and the second fixing member 23 are respectively disposed at both ends of the adjusting rod 21. The first fixing member 22 and the second fixing member 23 are both provided with the protrusion. The two fixing members fix from different directions, resulting in a better fixing effect.

[0034] Please see Figure 4 Specifically, in an optional embodiment of this application, the first fixing member 22 includes an mounting cylinder 221, a return spring 222, and a fixing rod 223. Limiting plates are provided at both ends of the mounting cylinder 221 along its length. Each of the two limiting plates has an adjustment hole for the fixing rod 223 to pass through. One end of the fixing rod 223 has the protrusion, and the other end has a limiting portion for limiting the adjustment hole. The return spring 222 is disposed inside the mounting cylinder 221, with both ends abutting against the two limiting plates. The return spring 222 is sleeved on the fixing rod 223, allowing the fixing rod 223 to freely extend and retract, making installation more convenient. When installation is required, the limiting portion of the fixing rod 223 is pulled, causing the protrusion to retract into the mounting cylinder 221. After aligning with the door process hole, the fixing rod 223 is released, allowing the protrusion to embed into the door process hole.

[0035] Specifically, in one optional embodiment of this application, the adjusting rod 21 includes a first rod body, a second rod body, and a third rod body. The second rod body is fixedly mounted on the mounting base 1. The two ends of the second rod body are respectively hinged to the first rod body and the third rod body, making the forming simple. Alternatively, the adjusting rod 21 can be formed by bending a single piece.

[0036] Specifically, in an optional embodiment of this application, the mounting base 1 is further provided with two reset members, which are respectively connected to the first segment rod and the third segment rod, making it easier to fix the mounting base 1.

[0037] Specifically, in one optional embodiment of this application, the second rod section includes a fixed cylinder and a telescopic rod. One end of the telescopic rod is movably disposed inside the fixed cylinder, and the other end of the telescopic rod is hinged to the first rod section. The end of the fixed cylinder away from the telescopic rod is hinged to the third rod section, which can adjust the length of the second rod section and is suitable for different process holes in more vehicle models.

[0038] The bottom of the mounting base 1 is also provided with a support rod for support. The support rod is inclined, and the end of the support rod away from the mounting base 1 is provided with a support part for abutting against the car door, which makes it easier to fix and support the mounting base 1.
