[0029] As Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 shown, the present application provides an aluminum alloy drive end cover, including: an end cover body 1 made of aluminum alloy material and a fixed ring 2 provided on one side thereof, the fixed ring 2 is used to connect with the motor, a plurality of jacks 201 are opened on the end face of the fixed ring 2, two card slots 202 are symmetrically opened in the jacks 201, a connecting component 3, the connecting component 3 is provided on the end cover body 1 and is used to connect the end cover body 1 and the fixed ring 2, and the connecting component 3 includes a clamping mechanism 301 provided on the end cover body 1 and an operating mechanism 302 provided on the clamping mechanism 301, the clamping mechanism 301 includes a trapezoidal block 3013 provided on the end cover body 1 and engaged with the card slot 202, the trapezoidal block 3013 is connected with the operating mechanism 302, and its extension or retraction into the card slot 202 is controlled by the operating end extending to the outside of the cylinder 3011 through the operating mechanism 302, a heat dissipation component 4, the heat dissipation component 4 is provided on the end cover body 1 and is used to dissipate heat from the motor, and the heat dissipation component 4 includes a dust-proof mechanism 401 and a shielding mechanism 402;

[0030] The snap connection mechanism 301 further includes a cylinder 3011 penetrating and installed on the end face of the end cover body 1 and inserted into the jack 201, a fixing rod 3012 fixedly installed inside the cylinder 3011, and a spring 3014 sleeved on the surface of the fixing rod 3012. Trapezoidal blocks 3013 are symmetrically slidably connected to the surface of the fixing rod 3012. Notches for the trapezoidal blocks 3013 to protrude are formed on the surface of the cylinder 3011. Both ends of the spring 3014 are connected to the two trapezoidal blocks 3013;

[0031] The operating mechanism 302 includes a movable rod 3021 penetrating and slidably connected to one end of the cylinder 3011, two connecting rods 3022 symmetrically hinged to one end of the movable rod 3021, and a moving ring 3023 fixedly connected to the other ends of a plurality of movable rods 3021. One ends of the two connecting rods 3022 are respectively hinged to the two trapezoidal blocks 3013;

[0032] As Figure 5 shown, the dust-proof mechanism 401 includes a dust-proof net 4011 installed in the end cover body 1 by screws. A plurality of heat dissipation holes 4012 are formed on one end face of the end cover body 1. An installation groove 4013 is formed at the center of one end face of the end cover body 1. A plurality of storage grooves 4014 respectively communicating with the heat dissipation holes 4012 and the installation groove 4013 are formed inside the end cover body 1;

[0033] As Figure 6 shown, the shielding mechanism 402 includes a rotating iron ring 4021 arranged in the installation groove 4013, an elastic gasket 4022 fixedly installed on one end face of the rotating iron ring 4021, a plurality of shielding plates 4023 fixedly installed on the circumferential surface of the rotating iron ring 4021, a handle 4024 fixedly installed on the other end face of the rotating iron ring 4021, and a limit magnet block 4025 rotatably connected to one end face of the end cover body 1 and magnetically adsorbed to the rotating iron ring 4021;

[0034] The elastic gasket 4022 can be deformed. The shielding plates 4023 are located in the storage grooves 4014. Two limit grooves 4026 abutting against the limit magnet block 4025 are formed on one end face of the rotating iron ring 4021;

[0035] As Figure 2 and Figure 3 shown, a plurality of connecting blocks 203 are fixedly installed on one end face of the fixing ring 2. Bolts are threadedly connected through the surfaces of the connecting blocks 203;

[0036] Working principle:

[0037] First, slip the fixed ring 2 over the outside of the drive motor and adjust the position of the fixed ring 2 so that the connecting block 203 aligns with the assembly hole on the drive motor. Then, insert a bolt through the connecting block 203 and thread it into the assembly hole on the drive motor, thereby mounting the fixed ring 2 on the drive motor. After that, install the dust-proof net 4011 on the end cover body 1 with screws;

[0038] Second, dock the mobile end cover body 1 with the fixed ring 2 so that the cylinder 3011 is inserted into the insertion hole 201. During the insertion process, the trapezoidal block 3013 is squeezed by the side wall of the insertion hole 201, and under the guidance of the inclined surface of the trapezoidal block 3013, the two trapezoidal blocks 3013 move closer to each other along the surface of the fixed rod 3012 and enter the cylinder 3011, squeezing the spring 3014. At the same time, the movable rod 3021 is driven by the connecting rod 3022 to move away from the cylinder 3011. When the cylinder 3011 passes through the insertion hole 201, at this time, the trapezoidal block 3013 aligns with the card slot 202, and the elastic force of the spring 3014 drives the two trapezoidal blocks 3013 to move away from each other, so that they extend out of the cylinder 3011 and are snap-connected to the card slot 202, achieving the effect of installing and fixing the end cover body 1. On the contrary, when disassembling the end cover body 1, just pull the moving ring 3023 to drive the multiple movable rods 3021 to slide away from the cylinder 3011. At the same time, under the action of the connecting rod 3022, the two trapezoidal blocks 3013 are driven to move closer to each other and enter the cylinder 3011 again, separating the trapezoidal block 3013 from the card slot 202. Then, the mobile end cover body 1 can be disassembled. Therefore, the effective and quick disassembly and installation of the end cover body 1 are realized;

[0039] Finally, when the drive motor is in use, the drive motor can be cooled through the dust-proof net 4011 and the heat dissipation holes 4012 to ensure the use effect. After disassembling the end cover body 1, the dust-proof net 4011 can be disassembled for cleaning. When the drive motor is not in use, press and rotate the rotating iron ring 4021 by holding the handle 4024. The elastic gasket 4022 deforms under force, causing the limit magnet block 4025 to separate from a corresponding limit slot 4026, and rotate the rotating iron ring 4021 to drive multiple shielding plates 4023 to leak out from the storage groove 4014, blocking the heat dissipation holes 4012 through the shielding plates 4023. At the same time, adjust the position of the limit magnet block 4025 so that it aligns with another limit slot 4026. Then, release the handle 4024, and the elastic gasket 4022 returns to its original state, driving the rotating iron ring 4021 to reset, so that the limit magnet block 4025 is snap-connected and adsorbed to the limit slot 4026 to fix the rotating iron ring 4021. On the contrary, release the fixation of the rotating iron ring 4021 and reverse it to open the heat dissipation holes 4012, thereby realizing the effect of blocking and sealing the heat dissipation holes 4012 when the motor is not in use, preventing dust from still adhering and accumulating on the dust-proof net 4011 through the heat dissipation holes 4012 when the motor is not in use, causing blockage.

[0040] The above are only the preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
