Description

A cast aluminum housing structure for automotive instrument panels Technical Field

[0001] This utility model relates to the field of automotive parts technology, and more specifically, to a cast aluminum shell structure for automotive instrument panels. Background Technology

[0002] Cast aluminum housings for automotive instrument clusters are a common component in the modern automotive industry. They are made of aluminum alloy through a casting process. Aluminum alloys are lightweight, high-strength, corrosion-resistant, and have good heat dissipation. Cast aluminum housings not only effectively reduce the overall weight of the car and improve fuel efficiency, but also ensure the stable operation of the instrument cluster in various harsh environments. In addition, through precise casting processes and reasonable structural design, cast aluminum housings can also provide good protection for automotive instrument clusters and extend their service life. However, commonly used cast aluminum housings require the inclusion of heat dissipation chambers and holes during the casting process, which not only increases the processing difficulty but also prevents the use of coolant for heat dissipation.

[0003] For example, CN215398473U discloses an integrated alloy frame for an automotive radio, including a base frame. A positioning base plate is movably mounted on the inner wall of the base frame. Positioning seats one on each of the left and right front sides of the base frame, and positioning seats two on each of the left and right top sides of the base frame. A flange is provided on the outer wall of the base frame. A base is provided on the rear end face of the base frame. An upper cover is movably mounted on the top of the base frame. Heat dissipation fins are provided on the right side of the top of the upper cover. A heat dissipation cavity is provided at the front end of the top of the upper cover. A base groove is provided on the outer wall of the upper cover. Heat dissipation holes are provided on both the heat dissipation cavity and the outer wall of the upper cover. Positioning holes are evenly distributed on the outer wall of the base frame. Positioning rods matching the positioning holes are provided at the bottom of the upper cover. The base frame is made of magnesium-aluminum alloy, and the upper cover is made of lightweight aluminum alloy. Inner grooves are evenly distributed on the top of the base frame, and fastening screw holes are provided on the inner walls of the inner grooves. Positioning guide posts matching the inner grooves are provided at the bottom of the upper cover.

[0004] As can be seen from the above-disclosed scheme, the integrated alloy frame needs to be set with a heat dissipation cavity during the casting process, and heat dissipation holes need to be set in the heat dissipation cavity. This not only increases the casting difficulty, but also makes it impossible to use coolant to cool the heat dissipation cavity with heat dissipation holes, thus reducing the heat dissipation effect. Summary of the Invention

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a cast aluminum shell structure for automotive instruments. This cast aluminum shell structure for automotive instruments uses a cooling groove formed by an outer frame and an inner frame to facilitate the placement of cooling pipes in combination with cooling inlet and outlet pipes. This not only prevents leakage of cooling pipes, but also enhances the cooling effect of the automotive instrument panel through the cooling pipes. Furthermore, the cooling groove, air inlet pipe, and air outlet pipe allow the cast aluminum shell to be air-cooled by connecting to ventilation pipes, reducing the processing difficulty of the cast aluminum shell.

[0006] To solve the above problems, the present invention adopts the following technical solution.

[0007] A cast aluminum housing structure for automotive instruments includes a cast aluminum housing body. The surface of the cast aluminum housing body is provided with a mounting groove, a through hole is provided in the middle of the mounting groove, and a connecting hole is provided at the bottom of the mounting groove. A heat dissipation structure is provided on the outer side of the mounting groove, and a sealing cap is fastened to one end of the heat dissipation structure. This cast aluminum housing structure for automotive instruments, through the cooling groove formed by the outer and inner frames, facilitates the placement of cooling pipes in combination with cooling inlet and outlet pipes. This not only prevents leakage from the cooling pipes but also enhances the cooling effect of the automotive instrument panel. Furthermore, the cooling groove, along with the air inlet and outlet pipes, allows the cast aluminum housing to be air-cooled via ventilation pipes, reducing the processing difficulty of the cast aluminum housing.

[0008] Furthermore, the heat dissipation structure includes an outer frame and an inner frame. One end of the outer frame and the inner frame are integrally formed with the surface of the cast aluminum shell body. The outer frame, the inner frame, and the surface of the cast aluminum shell body enclose a cooling groove. The cooling groove not only facilitates ventilation but also accommodates the cooling pipes and prevents the cooling pipes from directly contacting the instruments.

[0009] Furthermore, one end of the cooling tank is fixedly connected to an air inlet pipe and a cooling inlet pipe, and the other end of the cooling tank is fixedly connected to an air outlet pipe and a cooling outlet pipe. The inner walls of the air inlet pipe and the air outlet pipe are provided with internal threads, which facilitates connection with air-cooled pipes, thereby providing air-cooled heat dissipation for the instruments installed in the mounting tank.

[0010] Furthermore, a retaining strip is provided on the side of the outer frame. The retaining strip is frame-shaped and integrally formed with the outer frame. The retaining strip facilitates the fastening position of one side of the sealing cover.

[0011] Furthermore, the inner frame has a slot on its side, the slot has a U-shaped cross-section, and the height of the slot is lower than the height of the clip, so that the slot can be used to fix the other side of the sealing cover to the snap-fit ​​position.

[0012] Furthermore, the sealing cap is frame-shaped, and a limiting groove and a protrusion are provided at the bottom of the sealing cap. The inner wall of the limiting groove contacts and is pressed against the surface of the retaining strip. The sealing cap is made of high-density rubber, which facilitates fixation by elasticity.

[0013] Furthermore, the surface of the protrusion contacts and presses against the inner wall of the slot, which can prevent the sealing surface of the slot and the sealing surface of the protrusion from being on the same horizontal plane.

[0014] Compared with existing technologies, the advantages of this utility model are:

[0015] (1) This solution uses a cooling tank formed by the outer frame and the inner frame to facilitate the installation of cooling pipes in combination with cooling inlet pipes and cooling outlet pipes. This not only avoids leakage of liquid in the cooling pipes, but also enhances the cooling effect of the vehicle's instrument panel through the cooling pipes.

[0016] (2) This solution enables the cast aluminum shell to be air-cooled by connecting the cooling tank, air inlet pipe and air outlet pipe, thus reducing the processing difficulty of the cast aluminum shell. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1: Please refer to Figures 1-5. A cast aluminum housing structure for automotive instruments includes a cast aluminum housing body 1. The cast aluminum housing body 1 is further provided with several mounting structures. The composition and mounting structures are well known to those skilled in the art and will not be described in detail here. The surface of the cast aluminum housing body 1 is provided with a mounting groove 5. The mounting groove 5 is used to mount automotive instruments. Its mounting method and working principle are prior art. A through hole 51 is provided in the middle of the mounting groove 5. The inner wall of the through hole 51 is provided with protective cotton. The protective cotton contacts and squeezes against the side of the automotive instrument, which can not only seal the connection gap, but also prevent the automotive instrument from being damaged during assembly. A connection hole 52 is provided at the bottom of the mounting groove 5. The outer side of the mounting groove 5... A heat dissipation structure is provided, which includes an outer frame 2 and an inner frame 3. One end of the outer frame 2 and the inner frame 3 is integrally formed with the surface of the cast aluminum shell body 1. The outer frame 2, the inner frame 3 and the surface of the cast aluminum shell body 1 enclose a cooling groove 4. Cooling liquid pipes can be arranged in the cooling groove 4 and can be coiled in the cooling groove 4 to cool the cooling groove 4, thereby dissipating the temperature generated by the instrument operation. The cooling groove 4 not only facilitates ventilation, but also can accommodate the cooling pipes, and at the same time can prevent the cooling pipes from directly contacting the instrument. One end of the heat dissipation structure is fastened with a sealing cover 6, which is used to seal the cooling groove 4 to prevent dust from entering, and at the same time facilitates the cold air blown in by the air inlet pipe 41 to be blown out through the air outlet pipe 42, thereby improving the air cooling effect.

[0026] One end of the cooling tank 4 is fixedly connected to the air inlet pipe 41 and the cooling inlet pipe 43, and the other end of the cooling tank 4 is fixedly connected to the air outlet pipe 42 and the cooling outlet pipe 44. The inner walls of the air inlet pipe 41 and the air outlet pipe 42 are provided with internal threads, which facilitates the connection of the air inlet pipe 41 and the air outlet pipe 42 to the air-cooled pipe, thereby providing air-cooled heat dissipation for the instruments installed in the mounting slot 5. The side of the outer frame 2 is provided with a retaining strip 21. The retaining strip 21 is frame-shaped and integrally formed with the outer frame 2. The retaining strip 21 facilitates the fixing of the snap-fit ​​position on one side of the sealing cover 6.

[0027] The inner frame 3 has a slot 31 on its side. The slot 31 has a U-shaped cross-section and its height is lower than that of the clip 21. The slot 31 facilitates the fastening position of the other side of the sealing cover 6. The sealing cover 6 is frame-shaped and has a limiting groove and a protrusion at its bottom. The inner wall of the limiting groove contacts and presses against the surface of the clip 21. The sealing cover 6 is made of high-density rubber, which facilitates fixation by elasticity. The surface of the protrusion contacts and presses against the inner wall of the slot 31, which can prevent the sealing surface of the slot 31 and the sealing surface of the protrusion from being on the same horizontal plane.

[0028] This cast aluminum housing structure for automotive instruments can be fastened to the cast aluminum housing mounting bracket using connectors. The automotive instrument panel is then fixed to the mounting slot 5. Next, the air inlet of the automotive cooling duct is connected to one end of the air inlet pipe 41, and the air outlet of the automotive cooling duct is connected to the air outlet pipe 42. The automotive coolant circulation pipe is then coiled inside the cooling tank 4, with the inlet end extending out of the cooling inlet pipe 43 and the outlet end extending out of the cooling outlet pipe 44, before being connected to the automotive cooling system. Finally, the sealing cap 6 is fastened. During use, cold air enters the cooling tank 4 through the air inlet pipe 41 and is then discharged through the air outlet pipe 42. Meanwhile, the coolant circulates within the cooling pipes coiled in the cooling tank 4, thereby increasing the cooling effect. In addition, if the cooling pipes in the cooling tank 4 are damaged and leak, it can also prevent coolant from entering the instrument panel and causing damage. The cooling tank 4, which is enclosed by the outer frame 2 and the inner frame 3, facilitates the placement of cooling pipes in combination with the cooling inlet pipe 43 and the cooling outlet pipe 44. This not only prevents leakage from the cooling pipes, but also enhances the cooling effect of the vehicle's instrument panel. Furthermore, the cooling tank 4, along with the air inlet pipe 41 and the air outlet pipe 42, allows the cast aluminum shell to be air-cooled by connecting to the ventilation pipes, reducing the processing difficulty of the cast aluminum shell.
