Description

Technical Field

[0001] This utility model relates to the field of automotive technology, and in particular to an exhaust structure for an automotive electrophoresis front cover. Background Technology

[0002] The car body-in-white typically undergoes an electrophoresis process to form an electrophoretic paint film on both the inner and outer surfaces before subsequent painting processes. In the electrophoresis process, the front end (front of the car) of the body-in-white is rotated downwards and enters the electrophoresis pool to complete the electrophoresis. When the electrophoretic solution enters the interior of the front hood (between the inner and outer panels), any gases inside the hood are expelled through vents on the hood.

[0003] like Figure 1 and 2 As shown, the existing structure achieves ventilation by opening a hole 1 at the rear end of the inner panel of the front cover. This structural design affects the strength of the inner panel, causing structural defects. Figure 3 and 4 As shown, the purpose of venting is achieved by stamping and stretching a protrusion 2 at the rear end of the inner front panel, forming an venting channel between the inner and outer front panels. This structure makes the inner and outer front panels prone to deformation during the edge-sealing process, resulting in unreliable venting, an unstable edge-sealing structure, and difficulty in achieving complete edge sealing. This leads to poor edge sealing, corrosion, and even abnormal noise problems.

[0004] Therefore, how to provide an automotive electrophoretic front hood exhaust structure with a simpler and more reasonable structural design that can better guarantee structural strength and the edge-wrapping of the inner and outer front hood panels has become a technical problem that needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of the above-mentioned defects of the prior art, the technical problem to be solved by this utility model is how to provide an automotive electrophoretic front cover exhaust structure with a simpler and more reasonable structural design, which can better guarantee structural strength and better guarantee the edge-wrapping processing of the inner and outer front cover panels.

[0006] To achieve the above objectives, this utility model provides an exhaust structure for an automotive electrophoresis front cover, including a front cover body, the front cover body including a front cover outer panel and a front cover inner panel disposed inside the front cover outer panel; characterized in that: an exhaust hole is provided at the rear end of the front cover inner panel, extending through the thickness direction of the front cover inner panel; and a reinforcing rib is provided on the front cover inner panel on one side corresponding to the exhaust hole.

[0007] Thus, in the aforementioned automotive electrophoresis front hood exhaust structure, exhaust holes are machined and set on the inner panel of the front hood, and reinforcing ribs are set corresponding to the exhaust holes. The exhaust holes can better ensure exhaust during the electrophoresis process, and the reinforcing ribs can better ensure structural strength. The above structure can simultaneously meet the structural strength requirements without affecting the edging of the inner and outer panels of the front hood.

[0008] As an optimization, the exhaust port is designed with a waist-shaped structure, and the angle between the length direction of the exhaust port and the rear edge of the inner panel of the front cover, as well as the angle between the length direction of the exhaust port and one side edge of the inner panel of the front cover, are both set to acute angles.

[0009] This design of the exhaust vent as a waist-shaped structure makes it easier to manufacture. Furthermore, the angle of the exhaust vent is more rationally designed, ensuring that both ends of the exhaust vent on the inner front panel are edged by the outer front panel, and that the front and rear opening sizes of the exhaust vent are smaller, thus better guaranteeing the structural strength of the inner front panel.

[0010] As an optimization, the reinforcing rib is located on the front side of the exhaust hole on the inner panel of the front cover.

[0011] This design allows for a more rational placement of the reinforcing ribs, enabling better structural reinforcement of the exhaust vents on the inner panel of the front hood.

[0012] As an optimization, the reinforcing rib is formed by deep drawing from the inside to the outside on the inner panel of the front cover.

[0013] This makes it easier to process reinforcing ribs on the inner panel of the front cover.

[0014] As an optimization, the inner panel of the front cover is integrally stamped.

[0015] This makes the processing and manufacturing of the inner front panel more convenient.

[0016] As an optimization, there are two exhaust holes, and each of the two exhaust holes is respectively located on both sides of the rear end of the inner panel of the front cover.

[0017] In this way, the design of the location and number of vent holes is more reasonable, which can better discharge the gas between the inner and outer panels of the front cover during electrophoresis, thereby improving the quality of electrophoresis.

[0018] In summary, the above-mentioned structure has the advantages of simpler and more reasonable structural design, which can simultaneously ensure the structural strength of the front cover and electrophoretic venting, without affecting the edge banding processing of the inner and outer front cover panels, and ensuring the quality of the edge banding.

It should be noted that in the description of the present invention, terms such as "upper," "lower," "left," "right," "inner," and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are used only for the convenience of describing the present invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific manner. Therefore, they should not be construed as limitations on the present invention. Terms such as "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0026] like Figures 5 to 6 As shown, an exhaust structure for an automotive electrophoretic front cover includes a front cover body, which includes an outer front cover panel and an inner front cover panel 3 disposed inside the outer front cover panel; an exhaust hole 4 is provided at the rear end of the inner front cover panel, extending through the thickness direction of the inner front cover panel; and a reinforcing rib 5 is provided on the inner front cover panel on one side corresponding to the exhaust hole.

[0027] Thus, in the aforementioned automotive electrophoresis front hood exhaust structure, exhaust holes are machined and set on the inner panel of the front hood, and reinforcing ribs are set corresponding to the exhaust holes. The exhaust holes can better ensure exhaust during the electrophoresis process, and the reinforcing ribs can better ensure structural strength. The above structure can simultaneously meet the structural strength requirements without affecting the edging of the inner and outer panels of the front hood.

[0028] In this specific embodiment, the exhaust hole is designed with a waist hole structure, and the angle between the length direction of the exhaust hole and the rear edge of the inner panel of the front cover, as well as the angle between the length direction of the exhaust hole and one side edge of the inner panel of the front cover, are both set as acute angles.

[0029] This design of the exhaust vent as a waist-shaped structure makes it easier to manufacture. Furthermore, the angle of the exhaust vent is more rationally designed, ensuring that both ends of the exhaust vent on the inner front panel are edged by the outer front panel, and that the front and rear opening sizes of the exhaust vent are smaller, thus better guaranteeing the structural strength of the inner front panel.

[0030] In this specific embodiment, the reinforcing rib is located in front of the exhaust hole on the inner panel of the front cover.

[0031] This design allows for a more rational placement of the reinforcing ribs, enabling better structural reinforcement of the exhaust vents on the inner panel of the front hood.

[0032] In this specific embodiment, the reinforcing rib is formed by deep drawing from the inside to the outside on the inner panel of the front cover.

[0033] This makes it easier to process reinforcing ribs on the inner panel of the front cover.

[0034] In this specific embodiment, the inner front cover panel is integrally stamped.

[0035] This makes the processing and manufacturing of the inner front panel more convenient.

[0036] In this specific embodiment, there are two exhaust holes, and each of the two exhaust holes is respectively located on both sides of the rear end of the inner panel of the front cover.

[0037] In this way, the design of the location and number of vent holes is more reasonable, which can better discharge the gas between the inner and outer panels of the front cover during electrophoresis, thereby improving the quality of electrophoresis.

[0038] In summary, the above-mentioned structure has the advantages of simpler and more reasonable structural design, which can simultaneously ensure the structural strength of the front cover and electrophoretic venting, without affecting the edge banding processing of the inner and outer front cover panels, and ensuring the quality of the edge banding.

[0039] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort.
