[0022] As shown in Figures 2 to 4 , the connecting mechanism 200 further includes a sliding block 206, the sliding block 206 is slidably connected with the inner wall of the fixing block 202, a square groove 207 is formed in the outer wall of the sliding block 206, the outer walls of both sides of the shell 100 are detachably installed with the front cover 400 and the rear cover 500 through the connecting mechanism 200, the outer walls of the front cover 400 and the rear cover 500 are fixedly connected with the connecting block B 209, and the outer wall of the shell 100 is fixedly connected with the connecting block A 208.

[0023] With the above scheme: the outer walls of both ends of the shell 100 connected with the front cover 400 and the rear cover 500 are fixedly connected with the connecting block A 208, and the connecting block A 208 is connected with the connecting block B 209 through the connecting mechanism 200; in the normal state, the inner wall of the sliding block 206 is in contact with the inclined surface of the inclined block 203, as shown in Figure 4 , by pressing the sliding block 206, it can be moved into the inner wall of the fixing block 202, the inner wall of the sliding block 206 extrudes the inclined surface of the inclined block 203 to make it move, and since the protruding block 204 on the inclined block 203 is slidably connected with the inner wall of the fixing block 202, it can only move horizontally, so that the two groups of inclined blocks 203 drive the corresponding protruding blocks 204 to move horizontally to the middle at the same time, and the protruding block 204 moves into the inner wall of the fixing block 202, that is, the front cover 400 and the rear cover 500 can be disassembled and installed; the square groove 207 in the outer wall of the sliding block 206 is provided with two groups of front and rear, and the position of the sliding block 206 can be fixed through the limiting assembly, thereby locking the position of the protruding block 204.

[0024] As shown in Figures 2 to 4 , the bolt 201 is threadedly connected with the inner wall of the connecting block A 208, the two ends of the connecting spring 205 are fixedly connected with the outer walls of the two groups of inclined blocks 203, the protruding block 204 is clamped with the groove in the inner wall of the connecting block B 209, and the inclined block 203 is in contact with the inner wall of the sliding block 206.

[0025] According to the above scheme, before the front cover 400 and the rear cover 500 are installed, the bolt 201 can be screwed in the inner wall of the connecting block A 208, then the connecting block B 209 of the front cover 400 or the rear cover 500 is positioned corresponding to the fixed block 202, the position of the sliding block 206 is locked by the limiting assembly, the protruding block 204 is moved into the inner wall of the fixed block 202, then the connecting block B 209 is inserted on the fixed block 202, the limiting of the sliding block 206 is released, the protruding block 204 is popped out and is clamped with the inner wall groove of the connecting block B 209, and the connection and fixation of the front cover 400 and the rear cover 500 are completed.

[0026] As shown in Figure 4 and Figure 5 The limiting assembly further comprises a sliding rod 2004, the sliding rod 2004 is slidably connected in the inner wall of the fixed ring 2001, one end of the sliding rod 2004 is fixedly connected with the outer wall of the wedge-shaped block 2003, the other end of the sliding rod 2004 is in contact with the inner wall of the inclined groove 2006; the fixed ring 2001 is fixedly connected with the outer wall of the fixed block 202, one end of the reset spring 2002 is fixedly connected with the outer wall of the wedge-shaped block 2003, the other end of the reset spring 2002 is fixedly connected with the inner wall of the fixed ring 2001; the wedge-shaped block 2003 is slidably connected in the inner wall of the fixed ring 2001, and the wedge-shaped block 2003 is clamped with the square groove 207.

[0027] According to the above scheme, when the sliding block 206 is pressed, the inclined block 203 will move to the middle, and a group of square grooves 207 on the outer wall of the sliding block 206 will extrude the curved surface of the wedge-shaped block 2003, so that the wedge-shaped block 2003 moves to both sides and extrudes the reset spring 2002; when the sliding block 206 moves to another group of square grooves 207 corresponding to the wedge-shaped block 2003, the reset spring 2002 drives the wedge-shaped block 2003 to pop out and be clamped with the group of square grooves 207, and the sliding block 206 can be positioned at this time; because the elastic force of the connecting spring 205 will make the inclined block 203 have a tendency to move to both sides, but the position of the sliding block 206 is fixed, so the inclined block 203 cannot move to both sides, so that the inclined block 203 drives the protruding block 204 to be in a fixed position, and the protruding block 204 remains in the inner wall of the fixed block 202, and at this time the connecting block B 209 of the front cover 400 or the rear cover 500 can be inserted on the fixed block 202.

[0028] As shown in Figure 4 and Figure 5As shown, the limiting assembly, the wedge-shaped block 2003, the slide rod 2004 and the reset spring 2002 are all provided with two groups, which are symmetrically distributed in the inner wall of the fixed ring 2001 on both sides, and the two groups of slide rods 2004 are in contact with the inner wall of the two groups of inclined grooves 2006 on the rotating ring 2005; the rotating ring 2005 can rotate alone, and the fixed ring 2001 cannot rotate; when the rotating ring 2005 is manually rotated, the inclined groove 2006 will press the slide rod 2004, and since the slide rod 2004 can only move horizontally in the inner wall of the fixed ring 2001, the inclined groove 2006 will drive the slide rod 2004 to move to both sides at the same time, and the slide rod 2004 drives the corresponding wedge-shaped block 2003 to move synchronously, so that it moves to the inner wall of the fixed ring 2001 and is out of contact with the square groove 207, thereby releasing the limiting of the sliding block 206; in this state, the inclined block 203 will pop out to both sides due to the elastic force of the connecting spring 205, and will push out the sliding block 206; the inclined block 203 drives the protrusion 204 to pop out to both sides synchronously, and the protrusion 204 can be connected with the inner wall recess of the connecting block B209 on the front cover 400 and the rear cover 500, thereby completing the fixing of the front cover 400 and the rear cover 500; through the setting of the connecting mechanism 200, the rotating bolt 201 is screwed with the connecting block A208 during the first installation, and subsequent disassembly and installation can be completed by rotating the rotating ring 2005, that is, directly through the protrusion 204 and the inner wall recess of the connecting block B209 to complete the installation and fixing, which is more convenient and efficient, greatly improving the disassembly and installation efficiency.

[0029] As shown in Figures 6 to 10 The heat dissipation mechanism 300 includes a circular block 301, the inner wall of the circular block 301 is elastically connected with a rotating rod 302 through a volute spring 308, the outer wall of the rotating rod 302 is fixedly connected with a baffle 303, the inner wall of the circular block 301 is rotatably connected with a rotating block 304, the outer wall of the rotating block 304 is fixedly connected with a fixed rod 307, the outer wall of the rotating rod 302 is fixedly connected with a rotating wheel 305, the outer wall of the rotating wheel 305 is provided with a traction rope 306, the outer wall of the rotating block 304 is fixedly connected with a guide rod 309, and the outer wall of the rear cover 500 is fixedly connected with a control block 310. The inner wall of the control block 310 is provided with a guide groove 311.

[0030] By adopting the above scheme: the setting of the heat dissipation mechanism 300 can further improve the heat dissipation effect when the new energy automobile motor is running; the baffle 303 is provided with multiple groups, when the rear cover 500 is not installed, the baffle 303 is in a closed state, and after the rear cover 500 is fixed on the shell 100, multiple baffles 303 can be automatically opened at the same time, and the heat dissipation opening of the opened baffle 303 can improve the heat exchange efficiency of the fan inside the motor; when the rear cover 500 needs to be disassembled for maintenance of the motor, the baffle 303 can be automatically closed to prevent dust from entering the inside of the shell 100 when heat dissipation is not needed.

[0031] As shown in Figures 6 to 10As shown, the circular block 301 is fixedly connected to the inner wall of the housing 100, and the baffle 303 is rotatably connected to the inner wall of the housing 100; one end of the spiral spring 308 is fixedly connected to the inner wall of the circular block 301, and the other end of the spiral spring 308 is fixedly connected to the outer wall of the rotating rod 302; both ends of the traction rope 306 are fixedly connected to the outer walls of the fixed rod 307 and the rotating rod 302 respectively, and the guide rod 309 is in contact with the inner wall of the guide groove 311.

[0032] Using the above solution: Under normal conditions, due to the elastic force of the spiral spring 308, the rotating rod 302 and the baffle 303 are in a closed state. When the rear cover 500 is installed, with the connecting mechanisms 200 on connecting block A208 and connecting block B209 corresponding, the opening of the guide groove 311 on the control block 310 also corresponds to the guide rod 309. When the rear cover 500 moves towards the housing 100, the control block 310 fits against the outer wall of the housing 100. Because the guide groove 311 is designed with an inclination, such as... Figure 10 As shown, the guide groove 311 will squeeze the guide rod 309, causing it to move along the inner wall of the guide groove 311. Since the guide rod 309 can only move along the through groove on the housing 100, it will drive the rotating block 304 to rotate. The rotating block 304 rotates synchronously with the fixed rod 307. The fixed rod 307 pulls one end of the traction rope 306 to move. The other end of the traction rope 306 is connected to the rotating rod 302, but the rotating rod 302 can only rotate and cannot move. Therefore, it will pull the rotating rod 302 to rotate through the traction rope 306. The spiral spring 308 is compressed by the force, and the rotating rod 302 drives the baffle 3. 03 Synchronous rotation; After the rear cover 500 is installed, the guide rod 309 is fixed in position under the restriction of the guide groove 311, the rotating block 304 is fixed in position, and the position of the baffle 303 is also fixed by the traction rope 306, so that the heat dissipation vent is kept open after the protective shell is installed, which improves the heat dissipation effect during operation; After the rear cover 500 is removed, the guide groove 311 is disengaged from the guide rod 309, the rotating block 304 loses its limit and rotates in the opposite direction, the traction rope 306 is relaxed, and the rotating rod 302 rotates in the opposite direction and resets under the elastic force of the spiral spring 308, so that the baffle 303 is automatically closed.

[0033] Working principle and usage process of this invention: When the housing 100 is assembled with the front cover 400 and the rear cover 500, the four sets of connecting mechanisms 200 are tightened and fixed to the inner wall of the four sets of connecting blocks A208 by bolts 201 respectively. Then, the slider 206 is manually pressed to move towards the inner wall of the fixed block 202. The inner wall of the slider 206 presses the inclined surface of the inclined block 203, so that the two sets of inclined blocks 203 drive the protrusions 204 to move synchronously. At this time, the square groove 207 on the outer wall of the slider 206 presses the arc surface of the wedge block 2003, so that the wedge block 2003 moves to both sides and presses the return spring 2002. Continue to press the slider 206 until another set of square grooves 207 corresponds to the position of the wedge block 2003, the reset spring 2002 releases the elastic force to drive the wedge block 2003 to pop out, and is clamped with the set of square grooves 207, the position of the slider 206 is limited, and the protrusion 204 is locked in the state of being in the inner wall of the fixed block 202. Then align the connecting block B209 of the outer wall of the front cover 400 or the rear cover 500 with the position of the fixed block 202, and put the connecting block B209 into the outside of the fixed block 202, ensure that the groove in the inner wall of the connecting block B209 corresponds to the position of the protrusion 204; manually rotate the rotating ring 2005, the inclined groove 2006 extrudes the sliding rod 2004, the sliding rod 2004 drives the corresponding wedge block 2003 to move to both sides, the wedge block 2003 is separated from the square groove 207 and shrinks into the inner wall of the fixed ring 2001, and the limitation of the slider 206 is released. At this time, the connecting spring 205 releases the elastic force, pushes the two sets of inclined blocks 203 to move to both sides, and pushes the slider 206 outwards, the inclined block 203 drives the protrusion 204 to pop out synchronously and is clamped into the groove in the inner wall of the connecting block B209, when the protrusions 204 in the multiple sets of connecting mechanisms 200 are in the clamped state, the above steps are repeated, and the fixing of the front cover 400 and the rear cover 500 with the shell 100 is completed. In the process of moving the rear cover 500 to the shell 100, the control block 310 of the outer wall of the rear cover 500 is attached to the outer wall of the shell 100, the opening of the guide groove 311 is in contact with the guide rod 309, and as the rear cover 500 continues to move, the guide groove 311 extrudes the guide rod 309, forcing the guide rod 309 to drive the rotating block 304 to rotate synchronously, the rotating block 304 drives the fixed rod 307 to rotate, the fixed rod 307 drives the rotating rod 302 to rotate by overcoming the elastic force of the vortex spring 308 through the traction rope 306, and drives multiple baffles 303 to rotate synchronously; until the rear cover 500 is installed, the guide rod 309 is fixed in the guide groove 311, the rotating block 304 and the fixed rod 307 remain stationary, the traction rope 306 maintains a tensioned state, and the baffle 303 remains open, so that the heat dissipation port can be automatically opened, and the heat dissipation effect is improved when the motor is running. When it is necessary to repair or clean the motor by disassembling the front cover 400, the rear cover 500 and the shell 100, first press the slider 206 to make the protrusion 204 disengage from the groove in the inner wall of the connecting block B209, and lock the position of the slider 206 through the limiting assembly, and after multiple sets of connecting mechanisms 200 are operated according to the above operation, the front cover 400 and the rear cover 500 can be removed; through the setting of the connecting mechanism 200, only in the first installation, the connecting mechanism 200 is fixed through the bolt 201, and in the subsequent installation, the front cover 400 and the rear cover 500 can be connected and fixed through the protrusion 204, without rotating the bolt 201 for disassembly and installation each time, which is more convenient and efficient, and improves the disassembly and installation efficiency.

[0034] When the back cover 500 starts to move away from the shell 100, the control block 310 moves accordingly, the guide slot 311 drives the guide rod 309 to rotate reversely with the rotating block 304, the traction rope 306 loosens, the scroll spring 308 releases the elastic force to drive the rotating rod 302 and the baffle 303 to rotate reversely and reset, until the baffle 303 completely closes the heat dissipation port, so as to avoid dust from entering the shell 100 during maintenance or cleaning.
