Please refer to Figure 1 to Figure 5. According to an embodiment, a vehicle 1 includes a vehicle body 12 and an on-board computer 14 arranged in the vehicle body 12 (the outline of which is shown in dashed lines in FIG. 1 ). The on-board computer 14 includes a computer housing 142, a filter structure 144, an electronic component 146, and a fan 148. The computer case 142 has a case accommodating space 142a and a ventilation opening 142b communicating with the case accommodating space 142a. The filter structure 144 is detachably disposed in the ventilation opening 142b. Electronic component 146 (in order to simplify the diagram, it is represented by a solid block; in practice, it can be, for example, but not limited to, the system motherboard, memory module, hard disk, power supply module, or other components that generate heat during operation The electronic component) is arranged in the housing accommodating space 142a. The fan 148 is disposed in the housing accommodating space 142a and spaced apart from the ventilation opening 142b. The fan 148 (such as but not limited to an axial fan or a centrifugal fan) can generate an air flow F (shown as a hollow arrow in FIG. 5) to dissipate heat to the electronic component 146. The fan 148 has an air inlet 1482 and an air outlet 1484. The suction port 1482 faces the ventilation opening 142 b, so that the fan 148 can suck the air filtered by the filtering structure 144. The filtering effect of the filtering structure 144 can reduce the particulate content in the air entering the computer housing 142 through the ventilation opening 142b from the outside of the computer housing 142, that is, reducing the particulate content in the airflow F.

In addition, in this embodiment, the computer housing 142 includes a main housing 1422, which forms a housing accommodating space 142a and a ventilation opening 142b. Furthermore, the main housing 1422 includes a base 1422a and a top cover 1422b, and the top cover 1422b is detachably connected to the base 1422a to form a chassis accommodating space 142a. The top cover 1422b (one edge) and the base 1422a (three sidewall edges) form a ventilation opening 142b. But the implementation is not limited to this. For example, the main housing 1422 is implemented in other structural forms, such as a top cover 1422b and a base 1422a Pivot. For another example, the top cover 1422b alone forms the ventilation opening 142b.

The filter structure 144 is detachably connected to the main housing 1422 to close the ventilation opening 142b. In this embodiment, the filter structure 144 includes a bottom bracket 1442, a replaceable filter material 1444, and an upper cover 1446. The upper cover 1446 and the bottom bracket 1442 are connected to form a filter accommodating space 144a, and the replaceable filter material 1444 is accommodated in the filter accommodating space 144a. Wherein, the bottom bracket 1442 and the upper cover 1446 both have through hole structures 1442a, 1446a to allow air to circulate. The replaceable filter material 1444 can be implemented by a commonly used filter (for example, but not limited to, including one or more filters or cloths made of fibers or porous materials), and will not be described in detail. When the filter structure 144 is installed, the bottom bracket 1442 carrying the replaceable filter material 1444 is coupled to the upper cover 1446 from below the upper cover 1446 (for example, locked by screws 1447) to form the filter structure 144. Then, the upper cover 1446 can be assembled to the main housing 1422 to close the ventilation opening 142b. For example, the upper cover 1446 straddles the side wall of the base 1422a and abuts the top cover 1422b, and is fastened with screws. In practice, the filter structure 144 can also be modified such that the bottom bracket 1442 straddles the sidewall of the base 1422a and abuts against the top cover 1422b to close the ventilation opening 142b. The upper cover 1446 is only connected with the bottom bracket 1442 to form a filter material accommodating space 144a for accommodating a replaceable filter material 1444.

In addition, in this embodiment, the ventilation opening 142b is implemented in a single hole structure, but in practice it is also implemented in a grid structure; for example, the part of the top cover 1422b facing the fan 148 forms a grid structure as the ventilation opening 142b . At this time, the grid structure can be used as the bottom bracket 1442 of the filter structure 144, the upper cover 1446 is connected to the grid structure to form a filter material accommodating space, and the replaceable filter material 1444 is accommodated in the filter material accommodating space; in this example, The bottom bracket 1442 can be omitted. Or, the grid structure can be used as the upper cover 1446 of the filter structure 144, the bottom bracket 1442 is connected to the grid structure to form a filter material accommodating space, and the replaceable filter material 1444 is accommodated in the filter material accommodating space; in this example , The upper cover 1446 can be omitted. In addition, in this embodiment, the filter structure 144 adopts a detachable structure, so the bottom bracket 1442 and the upper cover 1446 can be disassembled to replace the replaceable filter material 1444, but the implementation is not limited to this. For example, the filter structure 144 is made of a single component (for example, the housing is detached non-recoverably). When its filtering function is insufficient, it needs to be replaced directly The entire filter structure 144.

In this embodiment, the computer casing 142 further includes a fan bracket 1424 for carrying the fan 148, and a detachable fan module (including the fan bracket 1424 and the fan 148) can be formed for easy installation or removal. The fan bracket 1424 is disposed in the chassis accommodating space 142a corresponding to the ventilation opening 142b. The fan bracket 1424 has a fan accommodating space 1424a, a top opening 1424b, and a side through hole 1424c. The top opening 1424b is aligned with the ventilation opening 142b. The fan 148 is disposed in the fan accommodating space 1424a and fixed to the fan bracket 1424, the suction port 1482 faces the top opening 1424b, and the exhaust port 1484 is connected to the side through hole 1424c and faces the electronic component 146. The air flow F generated by the fan 148 can pass through the side through hole 1424c to flow toward the electronic component 146 to dissipate heat. In practice, the side through hole 1424c can also be connected to a diversion structure to guide the airflow F to the electronic component 146 (for example, when the electronic component 146 is not arranged directly opposite the side through hole 1424c, or other structures interfere).

In addition, in practice, the on-board computer 14 may further include a tubular structure 150 (the outline of which is shown in dashed lines in FIG. 5), which is disposed in the housing accommodating space 142a. Wherein, one end 150a of the tubular structure 150 is close to the suction port 1482 (for example, connected to the suction port 1482), and the other end 150b is close to the filter structure 144 (for example, abutting against the bottom bracket 1442 of the filter structure 144). In this way, the fan 148 can more directly suck the air filtered through the filtering structure 144. In practice, the tubular structure 150 can also be formed by directly extending the structure of the suction port 1482 of the fan 148 upward. In addition, in this embodiment, the on-board computer 14 actually includes a plurality of fans 148, and the fan tray 1424 may include a plurality of partitions 1424d (drawn in dashed lines in FIG. 4) to divide the fan housing space 1424a into several sub-parts. Space to accommodate the fans 148 respectively. The fan 148 in each subspace can suck the air filtered by the filter structure 144. The partition 1424d helps to reduce the mutual interference between the fans 148 during operation, and also helps the efficiency of the fan 148 to suck in external air (filtered by the filter structure 144).

Please go back to Figure 1. In this embodiment, the vehicle body 12 has a cabin space 12a (including a space for the driver and passengers to ride and move), and the ventilation opening 142b of the computer housing 142 is connected to the cabin space 12a. Thereby, the fan 148 can suck in the air with a lower temperature in the cabin space 12a, thereby obtaining a better heat dissipation effect. Please also refer to Figure 6. In this embodiment, the car body 12 includes a rear seat arranged in the cockpit space 12a The chair 122, a speaker 124 located behind the rear seat 122 (the headrest), and a speaker grill 126. The on-board computer 14 is installed at the rear luggage compartment 12b close to the rear seat 122 (or regarded as being installed between the rear luggage compartment and the rear seat 122), for example, the computer housing 142 is fixed to the structural frame of the vehicle body 12 on both sides. The loudspeaker 124 is usually fixed on the structural panel or the decorative panel 128. The speaker grille 126 is exposed in the cockpit space 12a (which can also be fixed on the decorative panel 128) and simultaneously covers the speaker 124 and the filter structure 144 (of the onboard computer 14), which can be beautiful; among them, in FIG. 6, the speaker 124 and the filter The outline of the structure 144 covered by the speaker grill 126 is shown in dashed lines, and the outline of the computer casing 142 is also shown in dashed lines.

In addition, generally speaking, the speaker grille 126 is located in a prominent place in the cockpit space 12a (for example, behind the headrest of the rear seat 122 in this embodiment), and air is circulated. Therefore, when the air-conditioning of the vehicle 1 is turned on, the fan 148 can be used. The cold air is effectively sucked in through the ventilation opening 142b to improve the heat dissipation efficiency. Moreover, in some vehicle models, an air outlet 132 (indicated by a dotted square in FIG. 1) is provided above the middle of the cockpit space 12a (approximately between the front seat 130 and the rear seat 122), and the airflow of the cold air (The path is shown in FIG. 1 with multiple arrows). It can also effectively blow to the speaker grill 126, which is beneficial for the fan 148 to effectively suck cold air through the ventilation opening 142b. In addition, in practice, the filter structure 144 can also be exposed from the decorative plate 128 independently of the speaker grill 126. For example, the upper cover of the filter structure 144 and the surface of the decorative plate 128 are substantially coplanar, which also takes into account the aesthetics.

In addition, in this embodiment, although the onboard computer 14 is not directly installed in the cockpit space 12a, it can communicate with the cockpit space 12a through the ventilation opening 142b, so the cold air in the cockpit space 12a can be sucked. In practice, the on-board computer 14 must also be installed in the cockpit space 12a (for example, under the seat, as shown by the dashed line under the rear seat 122 in FIG. 1), and its ambient temperature is still lower than that of the rear luggage compartment 12b. It is lower, so it still helps to improve the heat dissipation efficiency of the on-board computer 14. Moreover, in some models, an air outlet 133 is provided at the inner floor of the cockpit space 12a, which can provide cold air under the rear seat 122, which helps to improve the performance of the on-board computer 14 (if it is installed under the rear seat 122) Heat dissipation efficiency. In addition, in actual operation, if the weather is hot outside the vehicle 1, even if the air-conditioning is not turned on in the vehicle 1, the air temperature in the cabin space 12a is in principle lower than other parts of the vehicle body 12 (such as the trunk 12b), so through ventilation Between the opening 142b and the cockpit space 12a Connected, the fan 148 can draw in the cooler air, which helps to dissipate heat.

In an embodiment of the present invention, the technology of the present invention can be applied to in-vehicle devices, such as self-driving cars, electric cars, or semi-self-driving cars, and so on.
