Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] This utility model provides, for example Figure 1-4 Shown:

[0029] Example 1:

[0030] A liquid-cooled axial heat dissipation and airflow guiding structure for an automotive traction motor, comprising:

[0031] Inner shell 1;

[0032] Flow guide 2 is formed on the outer wall of the inner shell 1;

[0033] The outer shell 3 is fitted onto the outer wall of the inner shell 1, and a water inlet 301 is provided on the top of the outer shell 3;

[0034] The filter assembly 6 includes a threaded post 603 fixedly connected to the top of the housing 3. The top of the threaded post 603 is provided with a mounting groove 602, and a filter screen 601 is inserted and connected inside the mounting groove 602.

[0035] Push component 7 is located at the bottom of filter screen 601.

[0036] It should be noted that the guide channel 2 is spirally formed on the outer wall of the inner shell 1, and the outer shell 3 is fitted onto the outer wall of the inner shell 1 to block the guide channel 2. The threaded post 603 is fixedly connected to the top of the outer shell 3, and the threaded post 603 is aligned with the water inlet 301. The mounting groove 602 is adapted to the filter screen 601, allowing the filter screen 601 to be inserted into the mounting groove 602. A sealing ring is provided at the connection between the filter screen 601 and the mounting groove 602 to seal the connection. The filter holes on the filter screen 601 have a diameter of 100 to 50 mesh, which are used to block impurities from entering the guide channel 2 during use. When coolant needs to enter the guide channel 2, the filter screen 601 blocks impurities in the coolant, preventing coolant from entering the guide channel 2 and thus avoiding the accumulation of impurities in the guide channel 2, which could affect heat exchange.

[0037] Specifically, the top of the outer casing 3 has a water outlet 302, and the top of the outer casing 3 is fixedly connected to a water outlet interface 4. The top of the threaded post 603 is threaded with a water inlet interface 5, which is used to press the filter screen 601.

[0038] It should be noted that when it is necessary to fix the position of the filter screen 601, the water inlet interface 5 is directly threaded onto the threaded post 603. The filter screen 601 is fixed inside the mounting groove 602 by the squeezing of the water inlet interface 5. A sealing gasket is provided at the connection between the water inlet interface 5 and the threaded post 603 to seal the connection between the water inlet interface 5 and the threaded post 603.

[0039] Example 2:

[0040] The drive component 7 is applied to the axial heat dissipation and airflow guiding structure in Embodiment 1;

[0041] Specifically, component 7 includes:

[0042] A pusher block 701 is located at the bottom of the filter screen 601;

[0043] Spring 702 is provided at the bottom of push block 701. Spring 702 is used to push push block 701. Limiting member 8 is provided at the bottom of spring 702.

[0044] Push rod 703 is fixedly connected to the bottom end of push block 701 and is inserted through the middle of spring 702.

[0045] Specifically, the limiting component 8 includes a fixing bracket 802 sleeved on the bottom of the push rod 703. A through hole is opened on the inner wall of the bottom end of the mounting groove 602. A mounting bracket 801 is fixedly connected to the side of the through hole opposite to the fixing bracket 802. A limiting plate 804 is provided at the bottom of the fixing bracket 802. The limiting plate 804 is fixedly connected to the bottom end of the push rod 703. A limiting rod 803 is fixedly connected to the bottom end of the fixing bracket 802. A limiting hole is opened at the top of the limiting plate 804. The limiting rod 803 is inserted and connected inside the limiting hole.

[0046] It should be noted that the through hole and the water inlet 301 are interconnected, allowing coolant to enter the interior of the water inlet 301 through the through hole. At least two mounting brackets 801 are provided, used to connect the fixing bracket 802 and the threaded post 603, thereby fixing the fixing bracket 802 inside the through hole. A limiting disc 804 is fixedly connected to the bottom end of the push rod 703, used to limit the upward movement distance of the push rod 703 and the push block 701. A spring 702 is provided between the push block 701 and the fixing bracket 802, used to push the push block 701 away from the fixing bracket 802. When installing the filter screen 601, first install the filter screen 60... 1. Insert the filter screen 601 into the mounting slot 602, and then squeeze it through the water inlet 5 to confine it inside the mounting slot 602. At this time, the spring 702 is compressed and deformed. When it is necessary to remove the filter screen 601, remove the water inlet 5. At this time, the spring 702 returns to its original shape, driving the push block 701 to push the filter screen 601 to one side, thereby pushing the top of the filter screen 601 out of the mounting slot 602, thus facilitating the removal of the filter screen 601. The number of limiting rods 803 is at least two, and the number of limiting holes is the same as the number of limiting rods 803. The multiple limiting rods 803 are arranged in parallel. During use, the multiple limiting rods 803 restrict the shaking of the limiting disc 804.
