[0032] In addition, it needs to be explained that the use of "first", "second" and the like to limit parts is only for the convenience of distinguishing the corresponding parts, and the above words have no special meaning if there is no further declaration, and therefore cannot be understood as limiting the protection scope of the utility model.

[0033] With reference to Figures 1 to 7 As shown in the figure, according to the embodiment of the utility model, a sealing element is provided, which is assembled between the shell 1 of the motor and the end cover 2 of the motor, and the sealing element comprises an inner ring wall 3, one end of the shell 1 has a plug-in part 4, the end cover 2 comprises a circumferential side wall 21 and an end wall 22, the inner ring wall 3 is assembled between the plug-in part 4 and the circumferential side wall 21, from the end of the inner ring wall 3 away from the end wall 22 to the end of the inner ring wall 3 towards the end wall 22, at least part of the thickness of the inner ring wall 3 shows a decreasing trend, and the end of the inner ring wall 3 towards the end wall 22 is the thinnest part of the thickness of the inner ring wall 3.

[0034] In the technical solution, the sealing element is assembled between the shell 1 and the end cover 2 of the motor for sealing and waterproofing, and for the assembly of the sealing element between the shell 1 and the end cover 2, it only needs to be fitted on the plug-in part 4 of the shell 1 and then buckled with the end cover 2, so the sealing and waterproofing mode of assembling the sealing element is obviously shorter in time and higher in production efficiency compared with the glue sealing and waterproofing mode. Meanwhile, the inner ring wall 3 of the sealing element is sharpened, so that the end of the inner ring wall 3 towards the end wall 22 of the end cover 2 is the thinnest part of the thickness of the inner ring wall 3. When the inner ring wall 3 is fitted on the plug-in part 4 and buckled with the end cover 2, the circumferential side wall 21 of the end cover 2 can first press and stick to the thinnest part of the inner ring wall 3 of the sealing element, and then slowly press and stick to the thicker position of the inner ring wall 3 until the end cover 2 is buckled in place. This makes the buckling of the end cover 2 easier, and the inner ring wall 3 of the sealing element is not easily displaced by the buckling end cover 2, so that the assembly position of the sealing element is more accurate and the sealing effect is better.

[0035] With reference to Figure 1 and Figure 2 As shown in the figure, a first inclined surface 5 is formed on the side of the inner ring wall 3 facing the circumferential side wall 21, and the first inclined surface 5 extends to the end of the inner ring wall 3 towards the end wall 22. The formation of the first inclined surface 5 makes the thickness of the inner ring wall 3 change linearly, so that the buckling of the end cover 2 is smoother when the end cover 2 is assembled.

[0036] With reference to Figure 2 As shown in the figure, the inner ring wall 3 is elastic, the inner ring wall 3 is in interference fit with the plug-in part 4 and the circumferential side wall 21, and at least two first protrusions are formed on the side of the inner ring wall 3 facing the circumferential side wall 21, which surround the inner ring wall 3, and each first protrusion is distributed on the inner ring wall 3.

[0037] In the embodiment, the end cover 2 is in interference fit with the inner ring wall 3 after being buckled. By arranging at least two first protrusions on the side of the inner ring wall 3 facing the peripheral wall 21, each first protrusion is deformed after being pressed and tightly adheres to the peripheral wall 21 of the end cover 2, thereby forming multiple layers of seals in sequence between the end cover 2 and the inner ring wall 3, so that the sealing effect between the end cover 2 and the inner ring wall 3 is better. The gap between each two adjacent first protrusions provides space for the deformation of each first protrusion under pressure.

[0038] Referring to Figure 2 As shown in the figure, at least two second protrusions are formed on the side of the inner ring wall 3 facing the insertion part 4, and each second protrusion is distributed on the inner ring wall 3.

[0039] In the technical scheme, the insertion part 4 of the shell 1 is in interference fit with the inner ring wall 3 after the end cover 2 is buckled. By arranging at least two second protrusions on the side of the inner ring wall 3 facing the insertion part 4, each second protrusion is deformed after being pressed and tightly adheres to the insertion part 4 of the shell 1, thereby forming multiple layers of seals in sequence between the shell 1 and the inner ring wall 3, so that the sealing effect between the shell 1 and the inner ring wall 3 is better. The gap between each two adjacent second protrusions provides space for the deformation of each second protrusion under pressure.

[0040] Referring to Figure 2 As shown in the figure, the inner ring wall 3 is connected to the end wall 22 at one end, and a connecting wall 6 is arranged around the inner ring wall 3. The connecting wall 6 extends along the radial direction of the inner ring wall 3. A stepped surface is formed on the shell 1 and surrounds the insertion part 4. The connecting wall 6 is assembled between the stepped surface and the free end of the peripheral wall 21.

[0041] In the embodiment, the connecting wall 6 of the sealing member is assembled between the stepped surface of the shell 1 and the free end of the peripheral wall 21 of the end cover 2, which means that the sealing member also forms a seal between the free end of the end cover 2 and the shell 1. Thus, the sealing member completely fills the gap between the shell 1 and the end cover 2, preventing rainwater from entering the motor cavity from different directions and damaging the electronic components, ensuring the dustproof and waterproof capability of the motor, and thus increasing the application field and use environment of the direct current plastic-sealed motor. Furthermore, the arrangement of the inner ring wall 3 and the connecting wall 6 also increases the bonding strength between the end cover 2 and the shell 1.

[0042] Referring to Figure 2 As shown in the figure, the connecting wall 6 is elastic, and the connecting wall 6 is in interference fit with the stepped surface and the free end of the peripheral wall 21. At least two third protrusions are formed on the side of the connecting wall 6 facing the stepped surface, and each third protrusion is distributed on the connecting wall 6.

[0043] In the technical scheme, when the end cover 2 is buckled, the stepped surface of the shell 1 and the connecting wall 6 are in interference fit. By arranging at least two third protrusions on the side of the connecting wall 6 facing the stepped surface, each third protrusion will deform and tightly fit the stepped surface of the shell 1 after being pressed, thereby forming multiple layers of seals distributed in sequence between the shell 1 and the connecting wall 6, so that the sealing waterproof effect between the shell 1 and the connecting wall 6 is better. The gap between each two adjacent third protrusions provides space for the deformation of each third protrusion under pressure.

[0044] Referring to Figure 2 As shown in the figure, at least two fourth protrusions are formed on the side of the connecting wall 6 facing the free end of the peripheral side wall 21, and each fourth protrusion is distributed on the connecting wall 6.

[0045] In this embodiment, when the end cover 2 is buckled, the free end of the end cover 2 and the connecting wall 6 are in interference fit. By arranging at least two fourth protrusions on the side of the connecting wall 6 facing the free end of the end cover 2, each fourth protrusion will deform and tightly fit the free end of the end cover 2 after being pressed, thereby forming multiple layers of seals distributed in sequence between the end cover 2 and the connecting wall 6, so that the sealing waterproof effect between the end cover 2 and the connecting wall 6 is better. The gap between each two adjacent fourth protrusions provides space for the deformation of each fourth protrusion under pressure.

[0046] Referring to Figure 2 As shown in the figure, the side of the connecting wall 6 away from the inner ring wall 3 is connected with an outer ring wall 7, the peripheral side wall 21 is between the outer ring wall 7 and the inner ring wall 3, and there is a gap between the outer ring wall 7 and the peripheral side wall 21.

[0047] In the technical scheme, the motor is in a state where the end cover 2 faces downward, as Figure 5 By making the sealing member also have an outer ring wall 7, the outer ring wall 7 can form a drainage for rainwater, so as to prevent the accumulation of rainwater at the connecting wall 6 of the sealing member and cause safety hazards. At the same time, the outer ring wall 7 also plays a shielding role for the end cover 2, which can block rain for the end cover 2 to reduce the erosion of rainwater on the end cover 2. Because the outer ring wall 7 shields the end cover 2, the motor of the present application is compatible with vertical and horizontal installation. Further, the gap between the outer ring wall 7 and the peripheral side wall 21 also means that when the end cover 2 is buckled on the shell 1, the peripheral side wall 21 of the end cover 2 is more easily inserted between the inner ring wall 3 and the outer ring wall 7 of the sealing member.

[0048] Referring to Figure 2As shown, the outer ring wall 7 has a fold wall 8 inclined to the direction close to the peripheral side wall 21, the fold wall 8 extends to the end of the outer ring wall 7 away from the connecting wall 6, and the included angle a between the fold wall 8 and the peripheral side wall 21 is 5°≤a≤15°. In this way, the gap between the end of the outer ring wall 7 away from the connecting wall 6 and the peripheral side wall 21 of the end cover 2 can be reduced, so that the possibility of water entering from the gap between the outer ring wall 7 and the peripheral side wall 21 can be reduced as much as possible on the basis of ensuring that the peripheral side wall 21 of the end cover 2 can be inserted into the inner ring wall 3 and the outer ring wall 7 of the sealing element. Preferably, the effect is optimal when a is 10°.

[0049] Referring to Figure 2 As shown, an arc-shaped chamfer 9 is formed at the joint of the outer ring wall 7 and the connecting wall 6. In the use state of the motor, when the end cover 2 is downward, the arc-shaped chamfer 9 can effectively slide the water droplets at the joint of the outer ring wall 7 and the connecting wall 6, and eliminate the water accumulation problem between the sealing element and the shell 1. It should be noted that a second inclined surface 12 is also formed on the side of the outer ring wall 7 away from the peripheral side wall 21, the second inclined surface 12 is connected with the arc-shaped chamfer 9 and the fold wall 8 respectively, and the second inclined surface 12 is inclined to the direction away from the peripheral side wall 21. The second inclined surface 12 has a drainage acceleration effect on the water droplets sliding from the arc-shaped chamfer 9, which can reduce the residence time of the water droplets on the outer ring wall 7 and make the water droplets quickly separate from the outer ring wall 7.

[0050] The utility model also provides a kind of outgoing line sealing structure, including outgoing line structure 10 and aforementioned sealing element, outgoing line structure 10 is in sealing element, shell 1 also has formed with avoiding gap, outgoing line structure 10 is clamped in avoiding gap place.

[0051] Referring to Figures 3 to 5 As shown, the outgoing line structure 10 includes an outgoing line seat 101 and an outgoing line nozzle 102. The outgoing line seat 101 is connected with the sealing element, and the outgoing line nozzle 102 is on the outgoing line seat 101. One side of the outgoing line seat 101 has a clamping portion 11. The outgoing line seat 101 is clamped in the avoiding gap, and the clamping portion 11 clamps the shell 1.

[0052] In the technical scheme, the clamping of the clamping portion 11 on the outgoing line seat 101 to the shell 1 makes the combination between the outgoing line structure 10 and the shell 1 more stable. Even if the outgoing line structure 10 is subjected to external force, it will not easily come out of the avoiding gap of the shell 1.

[0053] The utility model also provides a kind of motor, including aforementioned outgoing line sealing structure. Wherein, the motor of the utility model especially refers to a DC brushless plastic-sealed motor. When it is a DC brushless plastic-sealed motor, the shell 1 refers to the plastic-sealed shell of the DC brushless plastic-sealed motor.

[0054] Referring to Figure 2As shown, the insertion part 4 of the shell 1 is configured with a receiving groove surrounding the insertion part 4, and the one end of the inner ring wall 3 towards the end wall 22 is inserted into the receiving groove, which makes the combination between the inner ring wall 3 of the sealing element and the insertion part 4 of the shell 1 more compact, and can further improve the sealing effect. Meanwhile, the one end of the inner ring wall 3 towards the end wall 22 is inserted into the receiving groove of the insertion part 4, which is also beneficial to the installation and positioning of the inner ring wall 3 and the buckling of the end cover 2.
