[0032] The end cover of the motor is often provided with a shock-absorbing rubber ring to reduce the noise and wear caused by vibration of the end cover. The shock-absorbing rubber ring is mainly made of plastic material, which often produces structural deformation after long-term use, thereby reducing the shock-absorbing effect of the shock-absorbing rubber ring and even interfering with the normal operation of the motor.

[0033] In view of this, the present invention provides a shock-absorbing rubber ring 100 .

[0034] See also Figure 1 , Figure 4 and Figure 5 In one embodiment of the utility model, the shock-absorbing rubber ring 100 includes a rubber ring body 1 and a metal hoop edge 2, the metal hoop edge 2 is annularly arranged with a fracture 2a, the metal hoop edge 2 includes a covering portion 21 and two edging structures 22, the covering portion 21 covers the outer periphery of the rubber ring body 1, and the two edging structures 22 cover the opposite sides of the rubber ring body 1.

[0035] It should be noted that the material of the rubber ring body 1 is set to plastic material, which is easy to produce structural deformation, so a metal hoop edge 2 is provided, and the metal hoop edge 2 matches the peripheral structure of the rubber ring body 1, and is generally arranged in a ring shape. In order to facilitate the installation of the metal hoop edge 2 and make the metal hoop edge 2 and the rubber ring body 1 more closely matched, a fracture 2a is opened on the rubber ring body 1. Among them, the material of the metal hoop edge 2 can be stainless steel or aluminum alloy, which is not specifically limited here.

[0036] Specifically, the metal hoop edge 2 includes a covering portion 21 and two edging structures 22, wherein the metal hoop edge 2 is integrally formed, and the covering portion 21 covers the periphery of the rubber ring body 1, and the covering portion 21 may be attached to the periphery of the rubber ring body 1, or there may be a gap between the covering portion 21 and the periphery of the rubber ring body 1, and the two edging structures 22 cover the opposite sides of the rubber ring body 1 to prevent the rubber ring body 1 from deforming toward its opposite side structures. The edging structures 22 are attached to the opposite sides of the rubber ring body 1, so that the edging structures 22 have a better effect of improving the structural stability of the rubber ring body 1.

[0037] The technical solution of the utility model adopts a metal hoop edge 2 that covers the rubber ring body 1, so that the metal hoop edge 2 covers the outer periphery and two opposite sides of the rubber ring body 1, thereby preventing the structural deformation of the rubber ring body 1, thereby improving the structural stability of the shock-absorbing rubber ring 100, ensuring the shock-absorbing effect of the shock-absorbing rubber ring 100, and extending the service life of the motor.

[0038] In one embodiment, see Figure 4 A groove 11 is provided on the outer periphery of the rubber ring body 1, and the covering portion 21 includes two first protection segments 211 and a protrusion 212 protruding toward the groove 11. The protrusion 212 and the two first protection segments 211 and the two edging structures 22 enclose a first covering groove 23 and a second covering groove 24.

[0039] It should be noted that, in order to prevent the rubber ring body 1 and the metal hoop edge 2 from falling off in the circumferential direction, a groove 11 is provided on the outer circumference of the rubber ring body 1, wherein the groove 11 is an annular groove, and the covering portion 21 of the metal hoop edge 2 is provided with a protruding portion 212 protruding toward the groove 11, and the protruding portion 212 is adapted to the shape of the groove 11, so that the metal hoop edge 2 can be prevented from falling off the rubber ring body 1. Specifically, the protruding portion 212 and the two first protection segments 211 are integrally formed, the protruding portion 212 covers the groove 11 of the rubber ring body 1, and the first protection segment 211 covers other parts of the rubber ring body 1, wherein the protruding portion 212 and the two first protection segments 211 and the two edge wrapping structures 22 enclose a first wrapping groove 23 and a second wrapping groove 24, and the first wrapping groove 23 and the second wrapping groove 24 respectively wrap the parts on both sides of the groove 11 of the rubber ring body 1.

[0040] In one embodiment, see Figure 2 The raised portion 212 includes two connecting segments 212a and a second protective segment 212b, the two connecting segments 212a are respectively connected to the second protective segments 212b, the groove 11 has a groove bottom 111 and two opposite groove walls 112, the second protective segment 212b covers the groove bottom 111, the two connecting segments 212a respectively cover the two groove walls 112, and the length of the connecting segment 212a is greater than the length of the edging structure 22.

[0041] Specifically, the protrusion 212 includes two connecting sections 212a and a second protective section 212b, wherein the two connecting sections 212a and the second protective section 212b are integrally formed, the groove 11 has a groove bottom 111 and two opposite groove walls 112, the second protective section 212b covers the groove bottom 111, wherein there may be a gap between the second protective section 212b and the groove bottom 111, or the second protective section 212b may be attached to the groove bottom 111. In this embodiment, the two connecting sections 212a are attached to the two groove walls 112 respectively, so that the two connecting walls can better protect the structural stability of the rubber ring body 1 at the two groove walls 112, thereby preventing the two groove walls 112 from deforming. Considering that the groove 11 needs to cooperate with other brackets outside the motor to fix the relative position of the motor, the length of the connecting section 212a is greater than the length of the edging structure 22, even if the depth of the groove 11 is deep enough.

[0042] In one embodiment, see Figure 4 , avoidance grooves 12 are opened on opposite sides of the rubber ring body 1, and the avoidance grooves 12 avoid the edge binding structure 22.

[0043] Specifically, avoidance grooves 12 are opened on opposite sides of the rubber ring body 1, and the avoidance grooves 12 are used to avoid the edging structure 22. At the same time, the edging structure 22 is attached to two continuous groove walls 112 of the avoidance groove 12, which limits the relative position of the metal hoop edge 2.

[0044] In one embodiment, see Figure 3 , the depth of the groove 11 is set to H, and H satisfies H≥2mm.

[0045] Specifically, the groove 11 is used to avoid the bracket for fixing the motor, so the groove 11 should have a certain depth. The depth of the groove 11 is the distance from the notch of the groove 11 to the bottom 111 of the groove 11, and the depth of the groove 11 should not be too deep, otherwise it will affect the structural strength of the rubber ring body 1. Therefore, the depth of the groove 11 is set to be greater than or equal to 2mm, which can be 2mm, 3mm, or other data greater than 2mm.

[0046] In one embodiment, see Figure 3 The length of the edging structure 22 is set to L, and L satisfies L≥1.5mm.

[0047] It should be noted that the length of the edging structure 22, that is, the length of the edging structure 22 in the radial direction, should not be too long, otherwise the accuracy of the metal hoop edge 2 will be reduced, the difficulty of installing the metal hoop edge 2 will be increased, and the consumables of the metal hoop edge 2 will be increased. The length of the edging structure 22 should not be too short, otherwise the fixed relationship between the metal hoop edge 2 and the rubber ring body 1 will be affected. In this way, the length of the edging structure 22 is set to be greater than or equal to 1.5 mm, and can be 1.5 mm, 2 mm, or any length greater than 1.5 mm.
