Description

A molded water-cooling device for automotive underbody protection plates Technical Field

[0001] This utility model relates to the field of automotive underbody cooling technology, specifically a molded automotive underbody water cooling device. Background Technology

[0002] In today's booming automotive manufacturing industry, the quality of automotive underbody protection panels, as a crucial protective component of the vehicle's chassis system, directly impacts the vehicle's lifespan, driving safety, and overall performance. During production, automotive underbody protection panels are molded using a molding machine. Due to the high surface temperature after molding, they cannot be immediately packaged and transported; therefore, a cooling process is typically required.

[0003] Existing automotive underbody cooling systems consist of a cooling chamber, a filter plate, a water pump, multiple water pipes, and nozzles. A water reservoir is located at the bottom of the cooling chamber's inner wall to store coolant. The filter plate, installed inside the cooling chamber, supports the underbody panel to be cooled and filters impurities from the coolant water. The water pump is connected to the water reservoir via water pipes, providing the power source for cooling water delivery. The water pump is also connected via water pipes to nozzles located above the filter plate, ensuring that coolant is accurately sprayed onto the surface of the underbody panel placed on the filter plate. In actual operation, the operator places the underbody panel to be cooled stably on the upper surface of the filter plate, then starts the water pump. The coolant in the reservoir is drawn by the pump and transported through the water pipes to the nozzles, where it is sprayed onto the underbody panel surface at a certain pressure and speed, thus cooling the panel.

[0004] However, when using a nozzle to spray cooling water onto the surface of the car's underbody protection plate, the limited spray range and water flow distribution characteristics of the nozzle often cause the cooling water to concentrate on specific local areas of the underbody protection plate. This results in significant differences in the degree of contact between different parts of the underbody protection plate and the cooling water, leading to inconsistent temperature drops across different parts of the underbody protection plate and reducing the overall cooling efficiency of the underbody protection plate. Summary of the Invention

[0005] To address the aforementioned shortcomings, this utility model proposes a water-cooling device for a molded automotive underbody protection plate. The purpose is to solve the problem that existing automotive underbody protection plate cooling devices use nozzles to spray cooling water to cool the molded automotive underbody protection plate. However, due to the uneven coverage of the nozzles and the uneven distribution of water flow, the cooling water often concentrates in local areas, resulting in uneven cooling of the underbody protection plate surface and low cooling efficiency.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A molded automotive underbody protection plate water cooling device includes a cooling water tank, a lifting assembly, a working platform, an automotive underbody protection plate placement platform, a plurality of first fixing assemblies and at least two second fixing assemblies;

[0025] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "assembly," and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.

[0026] A molded automotive underbody protection plate water cooling device includes a cooling water tank 1, a lifting assembly 2, a working platform 3, an automotive underbody protection plate placement platform 4, a plurality of first fixing assemblies 5, and at least two second fixing assemblies 6.

[0027] The lifting assembly 2 is disposed inside the cooling water tank 1, and the working platform 3 is disposed on the top of the lifting assembly 2. The lifting assembly 2 is used to lift the working platform 3. The car underbody protection plate placement platform 4, a plurality of first fixing components 5 and two second fixing components 6 are all disposed on the top surface of the working platform 3. The plurality of first fixing components 5 and the two second fixing components 6 are distributed around the car underbody protection plate placement platform 4. The plurality of first fixing components 5 are used to fix the outer edge of the molded car underbody protection plate 7, and the two second fixing components 6 are respectively used to fix the front corners of the left and right sides of the molded car underbody protection plate 7.

[0028] This solution provides a water-cooling device for a molded automotive underbody protection plate. In this embodiment, as shown in Figures 1-3, two second fixing components 6 are provided. When cooling the molded automotive underbody protection plate 7 is required, the operator first introduces an appropriate amount of cooling water into the cooling water tank 1. Next, the lifting component 2 is activated, causing the working platform 3 to move upwards, thereby moving the automotive underbody protection plate placement platform 4 to a preset height above the water surface. Then, the molded automotive underbody protection plate 7 is placed on the automotive underbody protection plate placement platform 4. With the coordinated action of several first fixing components 5 and two second fixing components 6, the molded automotive underbody protection plate 7 is secured in all directions, preventing movement during the lifting process and ensuring accuracy and stability throughout the cooling process. Furthermore, the arrangement of several first fixing components 5 and two second fixing components 6 makes the fixing of the molded automotive underbody protection plate 7 more stable. Finally, the lifting assembly 2 is activated again. Under the action of the lifting assembly 2, the working platform 3 moves downward, thereby driving the car underbody protection plate placement platform 4 to move downward until the molded car underbody protection plate 7 is completely submerged in the cooling water and stays there for a period of time. The heat exchange between the cooling water and the molded car underbody protection plate 7 is used to cool down the molded car underbody protection plate 7 and ensure that it reaches the temperature state that meets the process requirements.

[0029] In this solution, the combined action of the cooling water tank 1, the lifting assembly 2, the working platform 3, the vehicle underbody protection plate placement platform 4, several first fixing components 5, and two second fixing components 6 ensures that the molded vehicle underbody protection plate 7 is completely submerged in cooling water. Under this submersion condition, the contact between different parts of the molded vehicle underbody protection plate 7 and the cooling water is more uniform, resulting in more even cooling of all parts of the molded vehicle underbody protection plate 7. Compared to traditional localized spray cooling methods, this solution improves the overall cooling efficiency of the molded vehicle underbody protection plate 7.

[0030] Preferably, the lifting assembly 2 includes a linear actuator motor 21, a base frame 22, two active scissor lifters 23, two passive scissor lifters 24, a connecting rod 25, and a top frame 26. The linear actuator motor 21 is fixed to the base frame 22. The top frame 26 is connected to the base frame 22 via the two active scissor lifters 23 and the two passive scissor lifters 24. The top frame 26 is located above the base frame 22. The working platform 3 is fixed to the top frame 26. The two active scissor lifters 23 are symmetrically distributed front and back, and the two passive scissor lifters 24 are symmetrically distributed front and back. The two active scissor lifters 23 are respectively connected to their respective passive scissor lifters 24 in an X-shaped hinge. The two active scissor lifters 23 are connected via the connecting rod 25. The drive end of the linear actuator motor 21 is connected to the connecting rod 25.

[0031] In this embodiment, as shown in Figure 4, when the working platform 3 needs to move downward, the linear push rod motor 21 is activated. The linear push rod motor 21 drives the connecting rod 25 to move downward, thereby driving the two active scissor lifters 23 to move downward, which in turn drives the two passive scissor lifters 24 to move downward, thus realizing the downward movement of the working platform 3.

[0032] Preferably, the first fixing component 5 includes a tilting cylinder 51, a swing rod 52, and a first pressure block 53. One end of the swing rod 52 is connected to the drive end of the tilting cylinder 51, and the other end of the swing rod 52 is connected to the first pressure block 53. In this embodiment, as shown in FIG2, the tilting cylinder 51 is a conventional cylinder, specifically a pneumatic actuator that uses compressed air to drive an output shaft to reciprocate within a certain angle range. By activating the tilting cylinder 51, the tilting cylinder 51 can drive the swing rod 52 to swing up and down, thereby causing the first pressure block 53 to swing up and down, realizing the clamping or loosening of the molded car underbody protection plate 7.

[0033] Preferably, the second fixing component 6 includes a rotary cylinder 61, a rotating rod 62, and a second pressure block 63. One end of the rotating rod 62 is connected to the drive end of the rotary cylinder 61, and the other end of the rotating rod 62 is connected to the second pressure block 63. In this embodiment, as shown in FIG3, the rotary cylinder 61 is a conventional cylinder, specifically a pneumatic actuator that uses compressed air to drive the output shaft to reciprocate within a certain angle range. Since protrusions 70 are provided at the corners near the front end on both sides of the molded car underbody panel 7, if a vertically tilting cylinder is provided at this location, the protrusions 70 will prevent the vertically tilting cylinder from tilting, thus failing to fix the molded car underbody panel 7. Therefore, by providing a rotary cylinder 61, which drives the rotating rod 62 to rotate horizontally, the rotation trajectory of the second pressure block 63 completely avoids the protrusions 70, thereby fixing the molded car underbody panel 7.

[0034] Preferably, the system also includes four lifting rings 8, all of which are fixed to the top surface of the working platform 3. Two of the lifting rings 8 are symmetrically distributed on the front side of the working platform 3, and the other two are symmetrically distributed on the rear side of the working platform 3. In this embodiment, as shown in Figure 1, by setting four symmetrically distributed lifting rings 8, a balanced force point is provided for the lifting operation of the entire water-cooling device, which not only ensures the stability of the entire water-cooling device handling process but also effectively improves the efficiency of the entire water-cooling device handling.

[0035] Preferably, the cooling water tank 1 has an inlet 11 on the lower left side and an outlet 12 on the upper right side. In this embodiment, as shown in Figure 1, cooling water is discharged into the cooling water tank 1 through the inlet 11. After the water level reaches the set capacity, the cooling water inside the cooling water tank 1 is discharged through the outlet 12, thereby forming a stable circulating cooling water system.

[0036] Preferably, the system also includes a controller 9, which is installed on the upper front side of the cooling water tank 1. The controller 9 is used to control the opening and closing states of the linear push rod motor 21, the tilting cylinder 51, and the rotary cylinder 61. In this embodiment, as shown in Figures 1-3, the operator can only control the opening and closing of the linear push rod motor 21 through the controller 9, thereby adjusting the lifting and lowering movement of the work platform 3 to cool the molded car underbody protection plate 7; it can also control the opening and closing of the tilting cylinder 51 and the rotary cylinder 61, driving the first pressure block 53 and the second pressure block 63 to perform clamping or releasing operations on the molded car underbody protection plate 7.

[0037] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without any inventive effort, and these embodiments will all fall within the scope of protection of this utility model.
