Description

Technical Field

[0001] This application belongs to the field of automotive technology, and specifically relates to a front carpet cooling grille for automobiles. Background Technology

[0002] In automobiles, a domain control mechanism is located under the crossbeam of the seat. This domain control mechanism needs to meet the heat dissipation performance requirements of the PAT (Personal Actuator), which requires a cutout design on the front carpet to meet the aforementioned heat dissipation requirements.

[0003] In existing technologies, a cut is made directly in the carpet, which exposes the heat dissipation vents and carpet edges, affecting the appearance. It also exposes the domain control module directly, and since there is no obstruction at the cut, foreign objects may fall in, affecting the operation of the domain control module. Summary of the Invention

[0004] To address the aforementioned issues, this application provides a front carpet cooling grille for automobiles.

[0005] A front carpet cooling grille for automobiles includes a front carpet assembly, a domain control mechanism, and a cooling grille. The front carpet assembly has a grille cutout. A cooling grille is installed at the grille cutout. The domain control mechanism is covered inside the front carpet assembly, and the domain control mechanism is cooled by the cooling grille. The cooling grille includes grille blades, a grille frame, and a grille mounting post. The grille blades are fixedly connected to the grille frame. A grille mounting post is fixedly connected to the back of the grille frame, and the grille frame is mounted on the front carpet assembly and covers the grille cutout via the grille mounting post.

[0006] Preferably, the periphery of the grid frame is provided with a grid matching edge, which is a thinning layer.

[0007] Preferably, the grille frame and the grille matching edge are integrally formed.

[0008] Preferably, when the grid blades are inside the grid frame, the grid blades are inclined upwards at an angle of 48°-50°, and a group of the grid blades are arranged in parallel.

[0009] Preferably, the grid blades are integrally formed by upper blades and lower blades, and the thickness of the upper blades is 0.3mm-0.35mm thicker than that of the lower blades.

[0010] Preferably, in the direction perpendicular to the surface of the front carpet assembly, the length of the grille blade is 2mm-2.5mm longer than the thickness of the front carpet assembly body.

[0011] Preferably, the cut size of the grille slit is slightly smaller than the installation size of the grille frame.

[0012] Preferably, the material of the front carpet assembly is a pile fabric.

[0013] Compared with the prior art, this application has the following advantages: The front carpet assembly is made of pile fabric, which can be needle-punched or tufted. The front carpet assembly is located on the vehicle's crossbeams, where a domain control mechanism is located. This domain control mechanism requires a grille cutout to integrate with the heat dissipation grille, resolving any misfitting issues. When the grille frame is mounted on the grille cutout via grille mounting posts, it can be installed by welding or snap-fitting. The grille frame contains grille blades with a 48°-50° angle. This angle effectively conceals the domain control mechanism, preventing it from being exposed from both inside and outside the vehicle. The upward-sloping layout of the grille blades also prevents foreign objects from falling and accumulating dust, while still allowing for proper heat dissipation. The grille blades have upper and lower blades, with the upper blade being 0.3mm-0.35mm thicker than the lower blade. This increased thickness enhances the overall rigidity of the grille blades, preventing deformation due to vehicle vibrations and further strengthening the visual concealment of the domain control mechanism, preventing heat from entering the vehicle. The internal components are visible from the outside of the vehicle; the lower blades are thinner, which reduces obstruction to airflow and ensures the airflow required for the domain control mechanism to dissipate heat, meeting the PAT heat dissipation performance requirements.

The objectives and other advantages of this application may be realized and obtained by means of the structures pointed out in the description, claims and drawings. Attached Figure Description

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0018] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 As shown, a front carpet cooling grille for automobiles includes a front carpet assembly 1, a domain control mechanism 8, and a cooling grille 3. The front carpet assembly 1 has a grille cutout 2. The cooling grille 3 is installed at the grille cutout 2. The domain control mechanism 8 is covered inside the front carpet assembly 1, and the domain control mechanism 8 is cooled by the cooling grille 3. The cooling grille 3 includes grille blades 5, a grille frame 4, and a grille mounting post 6. The grille blades 5 are fixedly connected to the grille frame 4. The grille mounting post 6 is fixedly connected to the back of the grille frame 4, and the grille frame 4 is installed on the front carpet assembly 1 through the grille mounting post 6 and covers the grille cutout 2. The material of the front carpet assembly 1 is a pile fabric. When the grid blades 5 are inside the grid frame 4, the grid blades 5 are inclined upwards at an angle of 48°-50°, and a group of the grid blades 5 are arranged in parallel. The grid blade 5 is integrally formed by upper blade and lower blade, and the thickness of the upper blade is 0.3mm-0.35mm thicker than that of the lower blade. The front carpet assembly 1 is made of pile fabric, which can be needle-punched or tufted. A domain control mechanism 8 is located at the crossbeam of the vehicle body. The domain control mechanism 8 requires a grille cutout 2 to align with the heat dissipation grille 3, resolving any misfitting issues. Simultaneously, when the grille frame 4 is mounted on the grille cutout 2 via the grille mounting post 6, it can be installed by welding or snap-fit. The grille frame 4 contains grille blades 5 with a design angle of 48°-50°. This 48°-50° tilt angle effectively blocks... The domain control mechanism 8 is shielded to prevent it from being exposed from both inside and outside the vehicle. The upward-sloping layout of the grille blades 5 prevents foreign objects from falling and dust from accumulating, while maintaining proper heat dissipation. The grille blades 5 consist of upper and lower blades, with the upper blades being 0.3mm-0.35mm thicker than the lower blades. This increased thickness enhances the overall rigidity of the grille blades 5, preventing deformation caused by vehicle vibrations and further enhancing visual concealment of the domain control mechanism 8, preventing internal components from being seen from either inside or outside the vehicle. The thinner lower blades reduce airflow obstruction, ensuring sufficient airflow for heat dissipation of the domain control mechanism 8 and meeting PAT heat dissipation performance requirements.

[0019] like Figure 6 As shown, in the direction perpendicular to the surface of the front carpet assembly 1, the length of the grille blade 5 is 2mm-2.5mm longer than the thickness of the body of the front carpet assembly 1. The front carpet assembly 1 itself has a certain thickness (determined by the needle-punching / tufting process of the pile fabric), while the grille blades 5 of the heat dissipation grille 3 need to pass through the grille cutout 2 of the front carpet assembly 1 to correspond with the domain control mechanism 8 below. The phrase "the length of the grille blades 5 is 2mm-2.5mm longer than the thickness of the front carpet assembly 1" refers to the length of the grille blades 5 extending in the forward direction (from the interior view) or the reverse direction (the side closer to the domain control mechanism 8) of the front carpet assembly 1, which is 2mm-2.5mm longer than the base thickness of the front carpet assembly 1 itself. This ensures that the grille blades 5 can completely cover the edge of the grille cutout 2, while maintaining a reasonable distance from the domain control mechanism 8 to avoid obstructing heat dissipation. The grille blades 5 being 2mm-2.5mm thicker than the front carpet assembly 1 can more effectively conceal the "exposed fabric" at the grille cutout 2. The design avoids the problem of the domain control mechanism 8 being visible from inside the vehicle; the grille blades 5 are slightly longer than the thickness of the front carpet assembly 1, which can form a more complete "barrier layer" at the grille cutout 2, reducing the risk of small foreign objects (such as debris or coins) falling into the domain control mechanism 8 through the grille cutout 2; the 2mm-2.5mm length is only a "slight protrusion", which will not be too close to the domain control mechanism 8, and can still ensure airflow between the blades to meet the PAT heat dissipation performance requirements.

[0020] like Figure 4 and Figure 5As shown, the periphery of the grid frame 4 is provided with a grid matching edge 7, which is a thinning layer; the grid frame 4 and the grid matching edge 7 are integrally formed. The cut size of the grille cut 2 is slightly smaller than the installation size of the grille frame 4; The pile fabric of the front carpet assembly 1 has a certain degree of flexibility and compressibility, while the heat dissipation grille 3 is a rigid structure (usually made of plastic). When the installation size of the grille frame 4 is slightly larger than the grille cutout 2, only slight pressure needs to be applied during assembly. The flexible edge of the front carpet assembly 1 will be "slightly squeezed" by the edge of the grille frame 4 and fit under the grille matching edge 7. This will not damage the fabric of the front carpet assembly 1, but will also allow the heat dissipation grille 3 and the front carpet assembly 1 to form a seamless overlap, reducing grille displacement caused by vibration during subsequent use and improving assembly stability. By using the "active size difference" of "the installation size of the grid frame 4 is slightly larger", the process error and assembly uncertainty of the flexible fabric are offset, which not only achieves convenient assembly of "positioning as soon as it is placed", but also solves problems such as exposed rough edges and gaps through "overlapping coverage".

[0021] Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
