Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of pure electric vehicle active grille shutter air guide structure, and particularly relates to a pure electric vehicle active grille shutter air guide structure and a pure electric vehicle. BACKGROUND

[0002] In order to meet the use requirements of the pure electric vehicle under different working conditions, improve the driving range and improve the energy utilization efficiency of the whole vehicle, it is necessary to finely design the thermal management control strategy, and the active grille shutter and other fine control strategies become effective means to reduce energy consumption.

[0003] For the pure electric vehicle, the battery fast charging and air conditioning refrigeration double-open working conditions under the idling condition need to be considered. Under this working condition, the heat load is large, and the poor sealing of the front-end cooling module is easy to cause more heat backflow, which makes the water temperature of the cooling system over-temperature, so the cooling effect is poor. For example, the patent document CN208827584U discloses an active grille shutter air guide structure, an air guide device and a vehicle, wherein the active grille shutter air guide structure comprises a cooling module, an air guide cover and an active grille. The inside of the air guide cover forms a flow guide channel, and the air guide cover has an inlet end and an outlet end, and the outlet end is connected to the cooling module. The inlet end is connected to the active grille. The cooling module and the active grille are communicated through the flow guide channel. After the air passes through the active grille, it will enter the flow guide channel and enter the cooling module along the flow guide channel. The air guide cover limits the overflow of the air after passing through the active grille. This active grille shutter air guide structure has good air intake effect, which ensures that enough air can enter the cooling module. However, since the active grille is installed on the upper side or the lower side of the front collision cross beam, it is an embedded active grille. If there is a deviation, the heat dissipation effect will be reduced. Moreover, the cooling module is vertically arranged and does not have the advantages of inclined arrangement to increase the storage space and reduce the wind resistance.

[0004] Therefore, it is necessary to develop a new pure electric vehicle active grille shutter air guide structure and a pure electric vehicle. SUMMARY

[0005] The purpose of the present application is to provide a pure electric vehicle active grille shutter air guide structure and a pure electric vehicle, which can realize good sealing of the front-end cooling module, flexible arrangement, reduced flow resistance and increased air intake.

[0006] In the first aspect, the pure electric vehicle active grille shutter air guide structure comprises an active grille, a first air guide cover, a second air guide cover and a front collision cross beam.

[0013] Optionally, the first air guide shroud is funnel-shaped, and the air inlet of the first air guide shroud is tightly sealed to the active air intake grille frame; this gathers more fresh air into the air guide channel, increasing the air intake volume.

[0014] Optionally, the upper surface of the second air guide shroud adopts an arc-shaped structure; guiding the airflow to the entire surface of the cooling module can improve the uniformity of the airflow.

[0016] Optionally, a protective net is also included, which is arranged between the air inlet of the second air guide and the cooling module to prevent gravel from splashing and damaging the cooling module, and to prevent fallen leaves, stones and dust from entering and accumulating at the inclined cooling module.

[0017] Optionally, the protective net is integrated into the second air guide cover.

[0018] Optionally, the second air guide shroud has symmetrical mounting holes on its left and right sides for installing a protective net. The protective net is in the shape of a grid strip and is arranged in a stepped manner following the cooling module.

[0019] Optionally, the second air guide and the protective net together form an angle of 53° with the horizontal direction.

[0020] Optionally, the front collision beam has an opening the size of the air guide hood, and the front collision beam is embedded in the air guide channel, which increases the size of the air guide channel and makes the relative positions of the grille inlet, the front collision beam and the cooling module more flexible.

[0022] The application has the following advantages: the application adopts the scheme of combining the external active air intake grille and the air guide structure between the external active air intake grille and the inclined cooling module, which improves the sealing performance of the air intake grille to the cooling module. The active air intake grille is arranged at the front bumper position, and compared with the built-in active air intake grille, the blade of the external active air intake grille does not need to correspond to the air outlet of the external grille, and the heat dissipation performance is better.

The second air guide cover is provided with a mounting position of the protective net, and the user can select whether to install the protective net according to the use requirement.

[0030] The application will be described in detail below with reference to the accompanying drawings.

[0031] As Figures 1 to 6 shown in the embodiment, an active grille shutter air guide structure for a pure electric vehicle includes an active grille shutter 3, a first air guide cover 1, a second air guide cover 2, a front collision beam 4, and a protective net 5. The active grille shutter 3 includes a plurality of active grille shutter blades 3-1 and an active grille shutter frame 3-2, and each active grille shutter blade 3-1 is rotatably installed on the active grille shutter frame 3-2. The active grille shutter frame 3-2 is installed on a front bumper 7. The bottom of the active grille shutter frame 3-2 extends in the x direction and is connected to the second air guide cover 2. The air inlet of the first air guide cover 1 is connected to the active grille shutter frame 3-2. The air outlet of the second air guide cover 2 is connected to an inclined cooling module 6. The front collision beam 4 is located between the first air guide cover 1 and the second air guide cover 2, and the air outlet of the first air guide cover 1 abuts against the front end face of the front collision beam 4, and the air inlet of the second air guide cover 2 abuts against the rear end face of the front collision beam 4. The protective net 5 is arranged between the air inlet of the second air guide cover 2 and the cooling module 6.

[0032] In the embodiment, the angle between the second air guide cover 2 and the protective net 5 and the horizontal direction is 53°, which reduces the occupation of the space in the Z direction.

[0033] As Figure 2 shown in the embodiment, there are six active grille shutter blades 3-1 in total, three on the left and three on the right, which are installed on the active grille shutter frame 3-2, and a motor 3-3 is arranged in the middle to drive the active grille shutter blades 3-1 to rotate. The active grille shutter blades 3-1 can be flipped under the drive of the motor 3-3 to close or open the air inlet of the active grille shutter 3. The left side shows the fully open state of the active grille shutter blades 3-1, and the right side shows the closed state of the active grille shutter blades 3-1.

[0034] As Figure 1 , Figure 3 , and Figure 4 shown in the embodiment, the first air guide cover 1 is trumpet-shaped, the air inlet of the first air guide cover 1 is tightly sealed against the active grille shutter frame 3-2 on three sides, and more fresh air is collected into the air guide channel, thereby improving the air inlet volume. The upper end face of the second air guide cover 2 adopts an arc-shaped structure to guide the air flow to the entire surface of the cooling module 6, which can improve the uniformity of the air speed.

[0035] As Figure 1 and Figure 5As shown, in the embodiment, a sealing strip 8 is arranged between the first air deflector 1 and the front collision beam 4, between the second air deflector 2 and the front collision beam 4, between the active air inlet grille frame 3-2 and the second air deflector 2, and between the second air deflector 2 and the cooling module 6, which has a good sealing effect, can reduce the heat backflow of the front compartment, improve the air intake utilization rate, enhance the cooling performance, and effectively reduce the energy consumption.

The protective net 5 is in the form of a grating strip and is arranged in a stepped manner with the cooling module 6. The protective net 5 is integrated into the second air deflector 2, so that the protective net 5 can avoid the damage of the cooling module 6 caused by the splashing of gravel, and prevent fallen leaves, stones and dust from entering and accumulating in the cooling module 6 arranged in an inclined manner. Since the protective net 5 will reduce the heat exchange capacity to a certain extent, the user can choose to install it according to the needs.

[0037] As Figure 1 and Figure 6 shown, on the premise of ensuring the strength, the front collision beam 4 is provided with an opening 4a with the width of the air deflector, and the front collision beam 4 is embedded into the air deflection channel, so that the size of the air deflection channel is increased, which is beneficial to improve the air intake.
