[0021] The following is a further detailed description of the specific implementation methods of the present invention by describing the embodiments with reference to the accompanying drawings, with the aim of helping those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention and to facilitate their implementation.

[0022] like Figure 1 and Figure 2 As shown, the automobile front engine hood spraying auxiliary support device includes an operating rod 1, a clamping plate 2 is provided at the end of the operating rod 1, a connecting rod 4 is fixedly connected to the inner side of the bottom of the clamping plate 2, and the end of the connecting rod 4 is fixedly connected to the limiting plate 3.

[0023] The device assists in manually opening and closing the front hood of the car during the processes of gluing and topcoat spraying. The clamping plate 2 can clamp and press the front post 14 of the lock, and the limiting plate 3 can limit the rear post 15 of the lock from coming out. The two work together to provide reliable support for the spraying of the front hood, so that the front hood is in an approximately horizontal posture, ensuring the surface appearance quality of the paint film.

[0024] like Figure 1 As shown, the clamping plate 2 is provided with a tightening bolt 5, and a nut 6 is fixedly connected to the outside of the clamping plate 2. The tightening bolt 5 penetrates the clamping plate 2 and engages with the nut 6, forming a U-shaped structure. The U-shaped design of the clamping plate 2 allows the internal spacing of the clamping plate 2 to be reduced by tightening the bolt 5, thereby achieving a clamping effect. The tightening bolt 5 is a standard galvanized component that meets national standards to meet strength requirements.

[0025] like Figure 1 As shown, the upper end of the limiting plate 3 is a U-shaped structure. The upper end of the limiting plate 3 is designed to be U-shaped, and the limiting plate 3 forms an outward opening. When in use, the inner side of the limiting plate 3 can contact the inner side of the lock rear pillar 15, thereby preventing the lock rear pillar 15 from falling out and improving the stability of the front hood when the device is in use.

[0026] like Figure 1 As shown, a support rod 7 is provided on the outer side of the bottom of the clamping plate 2, and the support rod 7 is arranged perpendicular to the operating rod 1. The above structure makes the contact area between the support rod 7 and the upper cross beam 16 of the water tank large. During the spraying operation, the support rod 7 is horizontal and in contact with the upper cross beam 16 of the water tank, and the entire device is located at the center of the support rod 7, which improves the balance and stability of the device.

[0027] like Figure 1 As shown, one side of the clamping plate 2 is fixedly connected to a connecting block 8, and the end of the operating rod 1 is provided with a connecting plate 9, which extends into the connecting block 8. A pin 10 extends through the connecting plate 9 and the connecting block 8. This structure realizes the disassembly and assembly function of the device, facilitating component replacement. The device can also be rotated along the pin 10 to a certain angle, preventing the operating rod 1 or the operating handle 11 from interfering with the front hood spraying process.

[0028] like Figure 2 As shown, the front hood is positioned above the clamping plate 2, with a water tank upper crossbeam 16 located below the clamping plate 2. This crossbeam 16 includes a front bracket 17. A latch 13 is located at the bottom of the front hood, comprising a front latch post 14 and a rear latch post 15. The clamping plate 2 presses against the front latch post 14, while the inner side of the limiting plate 3 contacts the rear latch post 15. A support rod 7 is mounted on the front bracket 17. The above structure represents the position of the device during spray painting of the front hood. The clamping plate 2 presses against the front latch post 14 by tightening the bolts 5, while the limiting plate 3 hooks onto the rear latch post 15. The support rod 7 supports the device and the front hood, ensuring the front hood is in a nearly horizontal position and prevents contact with the water tank upper crossbeam 16, which could damage the paint surface.

[0029] like Figure 1 As shown, the extrusion end of the tightening bolt 5 is fixedly connected to an extension plate 12, one end of which is trapezoidal. The use of the extension plate 12 increases the force arm when tightening the tightening bolt 5, reduces the tightening resistance, and facilitates use. In addition, the trapezoidal connection between the extension plate 12 and the tightening bolt 5 can prevent the extension plate 12 from breaking due to excessive torque.

[0030] like Figure 1 As shown, the end of the operating rod 1 is provided with an operating handle 11, which is bent into a square structure. The operating handle 11 extends the length of the operating rod 1 and extends the handheld end of the device to the outside of the front cabin cover for convenient use. The square operating handle 11 is convenient for the operator to pick up and hold or adjust the angle.

[0031] The operating rod 1 is welded to the operating handle 11, the two ends of the connecting rod 4 are respectively welded to the clamping plate 2 and the limit plate 3, and the support rod 7 is welded to the clamping plate 2. The above structure is fixed by welding, and the welding adopts carbon dioxide shielded welding, which is convenient for production and can reduce costs.

[0032] The operating rod 1, operating handle 11, and support rod 7 are all constructed from round steel. Using round steel facilitates production into the desired shape and reduces material costs. SUS304 stainless steel is used to meet the corrosion resistance requirements of coating production, while maintaining sufficient strength and rigidity to prevent significant deformation of auxiliary tools during operation, ensuring smooth operation. To ensure stability during use and transport, all components in the device require blunted edges, and weld spatter and burrs are ground and polished.

[0033] The usage process of the device is as follows: the device is placed between the front engine cover and the upper cross beam 16 of the water tank, the front engine cover single lock front column 14 is clamped between the clamping plate 2 structure, and the lock rear column 15 is fixed in the limit plate 3; the tightening bolt 5 is rotated 3-5 times to ensure that the lock 13 is stably clamped, and the support rod 7 is fixed to the front bracket 17 of the upper cross beam 16 of the water tank, and then the subsequent operation process can be carried out.

[0034] This auxiliary support device for spraying a front hood of an automobile solves the problem of easily damaged paint surfaces during spraying of the topcoat of the automobile hood. By clamping, limiting, and supporting the front hood lock 13, the hood is kept in a nearly horizontal position, providing reliable support during the spraying operation. This prevents the inner surface of the hood from contacting the upper crossbeam 16 of the water tank and causing damage to the paint surface, thereby improving the surface quality of the paint film on the front hood and reducing the cost of subsequent manual processing. The components of the device are easy to connect, the design is rational, and it is easy to disassemble, resulting in low application costs.

[0035] The above description of the present invention is provided as an example, in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described method. Any non-substantial improvements made using the method concepts and technical solutions of the present invention, or any application of the above-described concepts and technical solutions of the present invention to other situations without modification, are all within the scope of protection of the present invention.
