[0002] With the rapid development of new energy, the market scale of automotive brushless blowers is increasing day by day. The new energy vehicle battery module is a crucial component in new energy vehicles, responsible for storing and providing power.

[0003] The demand for heat dissipation in the battery module has increased, mainly considering two modes: air cooling and liquid cooling. In the air cooling mode, a cooling fan is used to introduce air into the battery pack, and the hot air is then discharged from the battery pack. In the liquid cooling mode, circulating water is used to take away the heat, and cooling fins are used to accelerate the heat dissipation. Comparing the air cooling and liquid cooling methods, the liquid cooling requires high maintenance in the later stage. Therefore, the utility model proposes a cooling blower for a new energy vehicle battery module. Summary of the Utility Model

[0010] The present utility model is further provided that: an extension ring is fixedly connected to the top of the upper volute, and the inner wall of the air outlet sealing sponge is closely sleeved on the outer wall of the extension ring and is flush with the top of the extension ring.

[0011] Through the above technical solution, after the entire blower is installed, the air outlet sealing sponge can be used to seal the leaked air volume at the connection, preventing the leakage of the air volume.

[0012] The present utility model is further provided that: the output shaft of the brushless motor is connected with a wind wheel through a fastening ring in snap connection, and a power plug is electrically connected to the bottom of the brushless motor.

[0013] Through the above technical solution, the power plug can be used to quickly connect the power supply to the brushless motor and start the brushless motor.

A bolt is penetrated through the inside of the strut, and the bottom of the bolt penetrates through the corresponding connection of the mounting bracket. A nut is threadedly connected to the outer wall of the bolt near the end face, and the nut abuts against the bottom of the connection of the mounting bracket.

[0017] Through the above technical solution, by using the shock pad to be installed between the lower volute and the mounting bracket, the vibration generated when the blower is working can be weakened by the shock pad, thereby reducing vibration and noise, and using bolts and nuts for connection and fixation, which is convenient for later maintenance.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] The following elaborates on the preferred embodiments of the present utility model in conjunction with the accompanying drawings, so that the advantages and features of the present utility model can be more easily understood by those skilled in the art, thereby making the protection scope of the present utility model more clearly defined.

[0028] Such as Figures 1-4As shown in the figure, a cooling blower for a new energy vehicle battery module includes a lower volute 100 and an upper volute 200 that are snap - connected to each other. At a position near the top of the outer wall of the lower volute 100, a plurality of clamping blocks 101 are fixedly connected evenly. At a position near the bottom of the outer wall of the upper volute 200, a plurality of clamping frames 201 are fixedly connected evenly. The plurality of clamping frames 201 are respectively snap - connected to the plurality of clamping blocks 101 in a corresponding manner, facilitating the upper volute 200 to be snap - connected to the clamping blocks 101 arranged on the outer wall of the lower volute 100, thereby forming a blower housing and facilitating the flow of air. A plurality of positioning frames 102 are fixedly connected to the outer wall of the lower volute 100, and all of them are open - type. The plurality of connecting parts 700 are respectively snap - connected to the inside of the plurality of positioning frames 102 through the grooves opened in the middle thereof. When connecting the blower and the mounting bracket 600, the connecting parts 700 can be quickly snap - connected to the positioning frames 102, and the blower is mounted on the mounting bracket 600 through the positioning frames 102. A extension ring 202 is fixedly connected to the top of the upper volute 200. The inner wall of the air outlet sealing sponge 500 is tightly sleeved on the outer wall of the extension ring 202 and is flush with the top of the extension ring 202. After the whole blower is installed, the air outlet sealing sponge 500 can seal the leaked air volume at the connection, preventing the leakage of air volume.

[0029] As Figure 3 shown, a brushless motor 300 is connected to the center of the lower volute 100 by screws. An air inlet sealing sponge 400 is sleeved at the connection of the air inlets of the lower volute 100 and the upper volute 200. An air outlet sealing sponge 500 is sleeved on the top of the upper volute 200. The output shaft of the brushless motor 300 is connected with a wind wheel 302 through a snap - connected fastening ring 301. The wind wheel 302 is made of a composite material of PA6 - GF30 or PA66 - GF30. The wind wheel 302 made of the composite material of PA6 - GF30 or PA66 - GF30 can play a role in high - temperature resistance during long - term use, improving its service life during use. A power plug 303 is electrically connected to the bottom of the brushless motor 300. Using the power plug 303 can quickly connect the power supply to the brushless motor 300, start the brushless motor 300, and its drive shaft drives the wind wheel 302 fixedly connected to the end face to rotate rapidly, thereby sucking in external air and discharging it into the battery module for air - cooling heat dissipation.

[0030] As Figure 5 and Figure 6As shown in the figure, the bottom of the lower volute 100 is bolted to the mounting bracket 600 through the connecting part 700. There are at least three connecting parts 700. The connecting part 700 includes a shock pad 701 clamped inside the positioning frame 102.

A nut 704 is threadedly connected to the outer wall of the bolt 703 near the end face, and the nut 704 abuts against the bottom of the connection of the mounting bracket 600. By installing the shock pad 701 between the lower volute 100 and the mounting bracket 600, the vibration generated when the blower operates can be weakened by the shock pad 701, thereby reducing vibration and noise. In addition, the bolt 703 and the nut 704 are used for connection and fixation, which facilitates the convenience during later maintenance.

[0031] When the present utility model is in use, first, the upper volute 200 is clamped to the block 101 provided on the outer wall of the lower volute 100 through the clamping frame 201, so as to form the blower housing, which is convenient for the circulation of air. Then, the air inlet sealing sponge 400 is sleeved at the air inlet of the blower, and the air outlet sealing sponge 500 is sleeved on the extension ring 202. Then, the shock pad 701 is clamped inside the positioning frame 102, the strut 702 is inserted into the shock pad 701, and finally the bolt 703 penetrates through the strut 702 to the bottom of the mounting bracket 600, and the nut 704 is threadedly connected to the bolt 703, so as to stably mount the entire blower on the mounting bracket 600. Moreover, the internal shock pad 701 can reduce the vibration and noise of the blower, and the air inlet and the air outlet are both provided with sealing sponges, which can effectively reduce the leakage of the air volume during heat dissipation.
