Detailed Description

In order to make the above objects, features and advantages of the present invention more comprehensible, embodiments of the present invention are described in detail below with reference to the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein, as those skilled in the art will be able to make similar modifications without departing from the spirit and scope of the present invention.

In a pure electric vehicle, the front cabin 10 is mainly used for placing a motor, a storage battery 14, a Power Distribution Unit (PDU), an On Board Charger (OBC), and other units for controlling the forward movement of the vehicle. Pure electric vehicles eliminate the engine relative to fuel-powered vehicles, thereby saving a significant amount of space in the front compartment 10.

In view of this, as shown in fig. 1 and 2, in one embodiment, an automotive front compartment 10 is provided that, by efficient arrangement, saves a separate, single large area in the front compartment 10 for use as a head-up tank 11. Specifically, as shown in fig. 1 and fig. 2, the front cabin 10 includes a front cabin 10, and a front spare box 11, a heat dissipation module 12, and an IPU (Intelligent Power Unit) module 13 that are all located in the front cabin 10, where a position of the front cabin 10 that is away from a cab 20 is a front end, the front spare box 11 is located at the front end of the front cabin 10, the heat dissipation module 12 is located below the front spare box 11, the IPU module 13 is located at a side of the heat dissipation module 12 that is close to the cab 20, and the IPU module 13 is integrated with a Power distribution Unit, an on-board charger Unit, and a voltage conversion Unit that are electrically connected to each other.

By reasonably arranging the relative positions of the heat dissipation module 12, the forecabin 11 and the IPU module 13, the space of the forecabin 10 is saved, and the space of the forecabin 11 is enlarged. Specifically, the IPU module 13 is disposed close to the cab 20, so as to minimize the occupation of the front space of the front cabin 10. And the power distribution unit, the vehicle-mounted charger unit and the voltage conversion unit are integrated into the IPU module 13 in a three-in-one manner, so that the arrangement space in the front cabin 10 is more compact. Thereby enabling the head-up tank 11 in the front compartment 10 to have a sufficient integration space.

Specifically, as shown in fig. 2, in order to improve safety, a firewall is disposed in the front cabin 10, and the firewall performs a flame retardant function between the front cabin 10 and the cab 20. So that the fire wall can prevent the spread of fire to the cab 20 to some extent in the event of a fire in the front compartment 10. The IPU module 13 is adjacent to the firewall, and a large space is reserved in front of the IPU module 13 as much as possible, so that the front spare box 11 can be conveniently arranged.

Further, the heat sink in the front compartment 10 is mainly used for reducing the temperature in the front compartment 10, so as to achieve a heat dissipation effect. In one embodiment, as shown in fig. 2, the heat dissipation module 12 is disposed obliquely with respect to the horizontal plane, so as to minimize the space occupancy of the heat dissipation module 12 in the longitudinal direction, in other words, minimize the height of the heat dissipation module 12 in the longitudinal direction, thereby increasing the space of the preparation box 11 located above the heat dissipation module 12. In order to ensure the heat dissipation effectiveness of the heat dissipation module 12, as shown in fig. 2, an air guiding cover 15 is further disposed in the front cabin 10, one end of the air guiding cover 15 is open and opposite to the heat dissipation module 12, and the other end of the air guiding cover 15 is open and faces the front of the front cabin 10. Therefore, the air guiding cover 15 can improve the air circulation at the position of the heat dissipation module 12, and even if the heat dissipation module 12 is arranged obliquely relative to the horizontal plane instead of being arranged perpendicular to the horizontal plane, the air guiding cover can also have a good heat dissipation effect.

Moreover, one end of the wind scooper 15 is opened toward the front of the front cabin 10, so that the heat dissipation effect of the heat dissipation module 12 can be improved by effectively utilizing the circulation of high-speed airflow during the driving process of the vehicle. Specifically, the shape of the wind scooper 15 may be matched with the shape of the space in the front cabin 10.

Specifically, in one embodiment, as shown in fig. 2, the difference in height between the thermal module 12 and the vehicle chassis gradually decreases in a direction away from the cab 20. In other words, the radiator module 12 is gradually inclined downward in a direction away from the cab 20, so that a large longitudinal height is reserved at the front end of the front compartment 10 to arrange the trunk 11, and the volume of the trunk 11 is further enlarged.

More specifically, the opening of the front spare box 11 faces, and the shape of the front spare box 11 may be irregular, in other words, the shape of the front spare box 11 may not be a cube or a rectangular parallelepiped. For example, after the heat dissipation module 12 is obliquely arranged, the closer to the front of the front cabin 10, the larger the space reserved in the longitudinal direction is, the closer to the front of the front cabin 10, the larger the depth of the front spare box 11 can be, the larger the bottom wall of the front spare box 11 can be in a stepped shape, the space reserved in the front cabin 10 is fully utilized, and meanwhile the integrity of the front spare box 11 is also guaranteed. The left-right width of the rear portion of the front spare box 11 can be set large relative to the left-right width of the front portion.

It should be noted that the dotted lines in fig. 1 and 2 only represent the approximate arrangement positions of the respective components in the front compartment 10, and do not limit the shapes of the respective components.

More specifically, in one embodiment, the thermal module 12 is inclined at an angle of no greater than 45 ° relative to horizontal. For example, the angle between the heat dissipation module 12 and the horizontal plane may be 30 °.

Further, in one embodiment, as shown in fig. 1, a storage battery 14 is further disposed in the front compartment 10, the storage battery 14 is located on a side of the trunk 11 close to the cab 20, and the storage battery 14 is electrically connected to the IPU module 13.

The storage battery 14 and the IPU module 13 are both disposed near the cab 20, and the front space of the front cabin 10 is vacated for use as the trunk 11, so as to improve the integrity of the trunk 11. And the storage battery 14 and the IPU module 13 are arranged adjacently, so that the length of a line between the storage battery and the IPU module is reduced, and the line arrangement in the front cabin 10 is simpler.

Further, in one embodiment, the battery 14 is disposed offset from the IPU module 13 in the left-right direction of the vehicle. In other words, the battery 14 is not located above the IPU module 13, which reduces the overall longitudinal height of the front compartment 10 and optimizes the vehicle profile.

Further, in another embodiment, a pure electric vehicle is provided, including the vehicle front compartment 10 described above.

By adopting the automobile front cabin 10 in any embodiment, the pure electric automobile has the front spare box 11 with higher integrity and larger space, and the automobile market competitiveness is improved.

Further, in one embodiment, the pure electric vehicle further includes a vehicle body and a rear-drive motor, the front cabin 10 is located in front of the vehicle body, the rear-drive motor is located behind the vehicle body, and the rear-drive motor is used for driving a rear wheel of the vehicle to rotate.

In other words, when the pure electric vehicle is a two-drive vehicle, the rear drive is selected, and the number of the required arrangement parts in the front cabin 10 is reduced.

Further, in one embodiment, the pure electric vehicle further includes a vehicle body, a front drive motor and a rear drive motor, the front cabin 10 is located in front of the vehicle body, the front drive motor is located in the front cabin 10, the front drive motor is used for driving front wheels to rotate, the rear drive motor is located behind the vehicle body, the rear drive motor is used for driving rear wheels to rotate, and the power of the front drive motor is smaller than that of the rear drive motor.

When the pure electric vehicle is a four-wheel drive vehicle, the rear drive motor is designed to be a high-power mode, the power of the front drive motor is reduced, and the size of the front drive motor is reduced on the premise of meeting the requirement of driving force, so that a large space is saved in the front cabin 10 and used as the front spare box 11.
