Description

Technical Field

[0001] This utility model relates to the field of machinery, and more particularly to the fixing structure of automotive electronic equipment modules, especially a screwless mounting structure for the fan of an in-vehicle intelligent cockpit controller module. Background Technology

[0002] Intelligent cockpits in automobiles typically include one or more controller modules to control the electronic equipment within the cockpit. These controller modules are housed in a highly sealed metal casing, with circuit boards mounted inside. These circuit boards contain numerous heat-generating components. Components generating significant heat (such as the CPU and AMP) require an active cooling system, with a metal heat sink attached to the heat source and a thermally conductive medium between them to dissipate the heat. Components generating particularly high heat require additional cooling fans to blow air onto the heat sink or exhaust air from the casing, creating forced convection between the hot air inside and the cool air outside. As market demands evolve, the functions of the chips within controller modules increase, leading to greater heat generation. Simultaneously, user-demanded operating environments are becoming increasingly stringent. Therefore, using fans for cooling controller modules has become an unavoidable choice. Current technology uses metal brackets and screws to fix the cooling fans inside the casing, which is inconvenient and inefficient. Furthermore, the metal brackets used to fix the cooling fans to the casing can generate considerable noise during operation, reducing user comfort. Utility Model Content

[0003] The purpose of this utility model is to provide a screwless fan mounting structure for an in-vehicle intelligent cockpit controller module, which aims to solve the technical problems of low fan installation efficiency and high noise in the prior art.

[0004] This utility model discloses a screwless fan mounting structure for an in-vehicle intelligent cockpit controller module, including a lower housing of the controller module, an upper housing of the controller module on the upper side of the lower housing, and an air outlet and an air inlet on the side of the lower housing, with the air inlet located on the opposite side of the air outlet.

[0005] A silicone sleeve is installed inside the air outlet in the lower housing of the controller module. A fan mounting hole is provided in the silicone sleeve. A fan is fixedly installed in the fan mounting hole. The radial cross-sectional shape of the fan mounting hole is adapted to the fan. Each of the two inner walls of the fan mounting hole is provided with a limiting protrusion for fixing the fan along the circumferential direction.

[0006] Limiting ribs are provided on both side walls of the silicone sleeve, and hooks that cooperate with the limiting ribs are provided on the inner wall of the lower shell of the controller module; downwardly extending positioning posts are provided on both side walls of the silicone sleeve, and positioning holes that cooperate with the positioning posts are provided on the bottom surface of the lower shell of the controller module; two parallel ribs are provided on the upper side of the silicone sleeve, the length direction of the ribs is parallel to the axial direction of the fan mounting hole, at least two grooves are provided on the upper surface of the ribs along their length direction, and a protrusion that is interference-fitted with the grooves is provided on the lower surface of the upper shell of the controller module.

[0007] Furthermore, a lead wire hole is provided in the side wall of the silicone sleeve, through which the power cord of the fan passes.

[0008] Furthermore, the sidewall thickness of the silicone sleeve is 1 mm.

[0009] Furthermore, the lower end of the positioning post is provided with a guide radius.

[0010] Compared with existing technologies, this invention offers significant and positive advantages. The fan is assembled within a silicone sleeve, forming a sub-assembly of the sleeve and fan. The limiting ribs of this sub-assembly are then engaged with hooks, and the positioning pins are inserted into positioning holes. The power cable of the cooling fan passes through the lead hole and connects to the circuit board. After the controller module's upper shell is covered, the protrusion at the bottom of the upper shell engages with the groove on the rib, pressing and securing the silicone sleeve to prevent loosening or movement. No screws or metal brackets are required during installation, simplifying the process and improving efficiency. Furthermore, without compromising the fan's cooling efficiency, the silicone sleeve effectively reduces noise during normal operation, enhancing user comfort. Attached Figure Description

[0019] like Figures 1-7 As shown, the present invention discloses a screwless fan mounting structure for a vehicle-mounted intelligent cockpit controller module, including a lower housing 1 of the controller module, an upper housing 2 of the controller module on the upper side of the lower housing 1, an air outlet 7 and an air inlet 8 on the side of the lower housing 1, and the air inlet 8 being located on the opposite side of the air outlet 7.

[0020] A silicone sleeve 4 is installed inside the air outlet 7 in the lower shell 1 of the controller module. A fan mounting hole 15 is provided in the silicone sleeve 4. A fan 5 is fixedly installed in the fan mounting hole 15. The radial cross-sectional shape of the fan mounting hole 15 is adapted to the fan 5. Each of the two inner walls of the fan mounting hole 15 is provided with a limiting protrusion 18 for fixing the fan 5 along the circumferential direction.

[0021] Limiting ribs 9 are provided on both side walls of the silicone sleeve 4, and hooks 10 that cooperate with the limiting ribs 9 are provided on the inner wall of the lower shell 1 of the controller module; downwardly extending positioning posts 13 are provided on both side walls of the silicone sleeve 4, and positioning holes 11 that cooperate with the positioning posts 13 are provided in the bottom surface of the lower shell 1 of the controller module; two ribs 19 are provided parallel to each other on the upper side of the silicone sleeve 4, the length direction of the ribs 19 is parallel to the axial direction of the fan mounting hole 15, and at least two grooves 12 are provided at intervals along the length direction on the upper surface of the ribs 19, and a protrusion 17 that is interference-fitted with the groove 12 is provided on the lower surface of the upper shell 2 of the controller module.

[0022] Furthermore, a lead wire hole 14 is provided in the side wall of the silicone sleeve 4, through which the power cord 16 of the fan 5 passes.

[0023] Furthermore, the sidewall thickness of the silicone sleeve 4 is 1 mm.

[0024] Furthermore, the lower end of the positioning post 13 is provided with a guide radius.

[0025] Specifically, the bump 17 is formed by a recessed reinforcing rib in the top plate of the upper shell 2 of the controller module.

[0026] Specifically, the specific structure and principle of the controller module lower shell 1, controller module upper shell 2, and fan 5 in this utility model, as well as other aspects not described in detail, all adopt well-known solutions in the prior art, which are already understood by those skilled in the art and will not be elaborated here.

[0027] The working principle of this embodiment:

[0028] The lower housing 1 of the controller module also has a rear socket cover 3. The heat-generating chip inside the controller module is mounted on a circuit board, and the aluminum alloy heat sink 6 is attached to the chip on the circuit board. The silicone sleeve 4 and the fan 5 are installed together between the inner wall of the lower housing 1 of the controller module and the aluminum alloy heat sink 6. The shape and size of the air outlet 7 are similar to the air outlet of the fan 5.

[0029] The silicone sleeve 4, viewed in cross-section, is a square with rounded corners, 2mm larger than the outer diameter of the fan 5. A nearly circular hole, slightly larger than the outer diameter of the fan blades, is cut out in the middle to form the fan mounting hole 15. The fan 5 can be installed inside the silicone sleeve 4 without obstructing the fan 5 from blowing hot air. The limiting protrusions 18 at both ends of the silicone sleeve 4 can prevent the fan 5 from coming out of the silicone sleeve 4.

[0030] The fan 5 is assembled inside the silicone sleeve 4, forming a sub-assembly of the silicone sleeve 4 and the fan 5. Then, the limiting rib 9 of the sub-assembly is snapped into the hook 10, and the positioning post 13 is inserted into the positioning hole 11. The power cable 16 of the fan 5 passes through the lead hole 14 and connects to the circuit board. After the controller module upper shell 2 is closed, the protrusion 17 at the bottom of the controller module upper shell 2 is inserted downwards into the groove 12 on the rib 19, pressing and fixing the silicone sleeve 4 to prevent it from loosening or shaking. No screws or metal brackets are needed during installation, making installation simple and improving efficiency. Furthermore, without affecting the heat dissipation efficiency of the fan 5, the silicone sleeve 4 effectively reduces the noise generated by the fan 5, improving user comfort.
