Detailed Implementation

[0035] To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the embodiments and accompanying drawings. Here, the illustrative embodiments and their descriptions are used to explain this application, but are not intended to limit it.

[0036] refer to Figures 1 to 10 ,like Figure 1As shown, this embodiment provides a roller shutter door motor with a waterproof structure, including: a motor body 1, an end cover 2, a waterproof outer cover 5, a motor shaft 3, and a sealing assembly. The end cover 2 is mounted on the motor body 1 by a first screw 203; the waterproof outer cover 5 is mounted on the end cover 2; a bearing 4 is connected between the motor shaft 3 and the end cover 2, and the motor shaft 3 extends outward after passing through the end cover 2 and the waterproof outer cover 5; the sealing assembly is disposed between the end cover 2 and the waterproof outer cover 5, between the waterproof outer cover 5 and the motor shaft 3, and between the end cover 2 and the motor shaft 3.

[0037] like Figure 2 As shown, a bolt 6 is installed between the end cap 2 and the waterproof outer cover 5, and a nut 7 is installed on the bolt 6. The nut 7 can lock the end cap 2 and the waterproof outer cover 5.

[0038] Specifically, such as Figure 3 , Figure 4 and Figure 6 As shown, the waterproof outer cover 5 has a first mounting hole 501, and the end cover 2 has a second mounting hole 205 that communicates with the mounting hole 501. The mounting bolt 6 passes through the first mounting hole 501 and the second mounting hole 205 and is threadedly connected to the nut 7.

[0039] like Figure 3 and Figure 4 As shown, the sealing assembly includes a sealing gasket 8, a waterproof rubber sleeve 10, and a sealing ring 13. The sealing gasket 8 is sealed between the end cap 2 and the waterproof outer cap 5; the waterproof rubber sleeve 10 is sealed between the waterproof outer cap 5 and the motor shaft 3; and the sealing ring 13 is sealed between the end cap 2 and the motor shaft 3.

[0040] Preferably, the end cap 2 is provided with a third sealing groove 201, and the waterproof outer cover 5 is provided with a fourth sealing groove 502. When the bolt 6 and the nut 7 are threaded together to fix the end cap 2 and the waterproof outer cover 5 together, the sealing gasket 8 is held and accommodated between the third sealing groove 201 and the fourth sealing groove 502, thus playing a sealing role.

[0041] like Figure 5 and Figure 7As shown, the left side of the sealing gasket 8 is provided with a positioning groove 801 and a first sealing flange 802. The positioning groove 801 is located outside the first sealing flange 802. The right side of the waterproof outer cover 5 is provided with a positioning protrusion 503 that can be adapted to the positioning groove 801 and a first sealing groove 504 that can be adapted to the first sealing flange 802. Through the cooperation of the positioning groove 801 and the positioning protrusion 503, the positioning of the waterproof outer cover 5 when installed on the end cover 2 can be more accurate.

The limiting flange 101 abuts against the annular protrusion 505 and the shoulder of the motor shaft 3. This arrangement ensures that the waterproof rubber cylinder 10, the waterproof outer cover 5, and the motor shaft 3 are all well sealed.

[0044] Preferably, the sealing gasket 8 has a second through hole 804 in the middle for allowing the motor shaft 3 to pass through, and the annular protrusion 505 and the limiting flange 101 are both accommodated in the second through hole 804.

[0045] Preferably, a stepped groove 204 is provided in the end cover 2, the bearing 4 is installed on the right side of the stepped groove 204, and a bearing cover 9 that can restrict the bearing 4 is installed on the left side of the stepped groove 204 by a third screw 14. By setting the bearing cover 9, the bearing 4 can be limited, thereby ensuring that the bearing 4 is securely installed.

[0046] like Figure 10 As shown, the bearing cover 9 has an installation groove 901, and a sealing ring 13 is installed in the installation groove 901. The sealing ring 13 is sleeved on the motor shaft 3. The sealing ring 13 has a number of sealing lips 1301 that can abut against the motor shaft 3.

[0047] Preferably, a cover plate 11 is mounted on the bearing cover 9 by a second screw 12, and the cover plate 11 can confine the sealing ring 13 within the mounting groove 901. The bearing cover 9 is installed in the stepped groove 204, which facilitates the replacement of the bearing 4; the cover plate 11 is installed in the bearing cover 9, which facilitates the replacement of the sealing ring 13.

[0048] In addition, the cover plate 11 has a groove 1101 for hiding the head of the second screw 12.
