[0045] The present invention provides a shock-absorbing ring 100 .

[0046] Reference Figures 1 to 8In an embodiment of the present invention, the shock-absorbing ring 100 includes a ring body 10 and a bracket 20; the bracket 20 is built into the ring body 10, and the bracket 20 is used to provide radial support force to the shock-absorbing ring 100, and the bracket 20 includes a first elastic bracket and a second elastic bracket, and the first elastic bracket is arranged on the inner side of the second elastic bracket; or, the second elastic bracket is arranged on the inner side of the first elastic bracket; wherein, under the same deformation amount, the elastic modulus of the bracket 20 is greater than the elastic modulus of the ring body 10. Such a setting can reduce the risk of excessive deformation of the shock-absorbing ring 100 due to radial force, improve the radial strength of the shock-absorbing ring 100, and thus extend the service life of the shock-absorbing ring 100.

[0047] The shock-absorbing ring 100 is installed on the end cover 200 of the motor 1000. Then, the shock-absorbing ring 100 is arranged between the motor 1000 and the installed fan housing to improve the vibration noise of the motor 1000. In order to prevent the shock-absorbing ring 100 from deforming or even falling off under long-term working conditions, and because the shock-absorbing ring 100 is mainly subjected to radial force under working conditions, the present application sets a bracket 20 in the ring body 10, so that the bracket 20 can provide radial support force to the shock-absorbing ring 100, thereby effectively reducing the damage of the radial force to the shock-absorbing ring 100 as a whole, ensuring the shock-proof effect of the shock-absorbing ring 100, and extending the service life of the shock-absorbing ring 100; and, because the bracket 20 has a certain thickness, it can prevent the shock-absorbing ring 100 from deforming in its axial direction to a certain extent, that is, the bracket 20 can provide axial support force to the shock-absorbing ring 100, thereby helping to improve the stiffness of the shock-absorbing ring 100, further ensuring the shock-proof effect of the shock-absorbing ring 100, and extending the service life of the shock-absorbing ring 100.

[0048] Specifically, the ring body 10 is made of a flexible material to ensure the shock-absorbing and energy-absorbing effect of the shock-absorbing ring 100. The ring body 10 covers the bracket 20, which can protect the bracket 20 to a certain extent. At the same time, it also reduces the risk of the bracket 20 extending and contacting the external structure. The bracket 20 can be covered inside the ring body 10 by secondary injection molding, which simplifies the manufacturing process and improves production quality and efficiency. A groove can also be opened on the ring body 10, and the assembly of the ring body 10 and the bracket 20 can be achieved by embedding the bracket 20 into the groove.

[0049] The bracket 20 includes a first elastic bracket and a second elastic bracket, which can assist the bracket 20 in deforming, thereby improving the overall shockproof performance and structural strength of the bracket 20 and reducing the risk of structural failure of the bracket 20; wherein, the first elastic bracket is arranged on the inner side of the second elastic bracket, or the second elastic bracket is arranged on the inner side of the first elastic bracket, that is, the first elastic bracket and the second elastic bracket are arranged along the radial direction of the bracket 20, so that by increasing the radial span of the bracket 20 in the shock-absorbing ring 100, cooperating with the deformability of the first elastic bracket and the second elastic bracket themselves, the radial support effect of the bracket 20 on the ring body 10 can be enhanced, and the shockproof effect of the shock-absorbing ring 100 can be improved, thereby achieving low-noise operation of the motor 1000.

[0050] In order to ensure that the bracket 20 can provide radial support force, under the condition of the same deformation amount, the elastic modulus of the bracket 20 is limited to be larger than the elastic modulus of the ring body 10. The elastic modulus is an indicator reflecting the material's ability to resist elastic deformation. Therefore, the deformation ability of the bracket 20 is weaker than that of the ring body 10, and it has strong rigidity and high hardness. When the shock-absorbing ring 100 is subjected to radial force, the ring body 10 is deformed by the force and buffers the radial force and absorbs energy. The bracket 20 can also be deformed by the force and buffers the radial force together with the ring body 10. At the same time, the bracket 20 can also provide radial support force to the ring body 10, reduce the risk of structural failure of the ring body 10 due to excessive deformation, and improve the service life and shockproof performance of the shock-absorbing ring 100.

[0051] In the technical solution of the present invention, by disposing a bracket 20 within the ring body 10 and, under the condition of the same deformation, the elastic modulus of the bracket 20 is greater than that of the ring body 10, the bracket 20 can provide radial support force to the shock-absorbing ring 100, reduce the damage of the radial force to the shock-absorbing ring 100 as a whole, ensure the shock-proof effect of the shock-absorbing ring 100, and extend the service life of the shock-absorbing ring 100; and because the bracket includes a first elastic bracket and a second elastic bracket, when the ring body 10 deforms, the first elastic bracket and the second elastic bracket deform accordingly and, together with the ring body 10, cushion and absorb energy, which helps to further ensure the shock-proof effect of the shock-absorbing ring 100. In addition, the bracket 20 can also prevent the shock-absorbing ring 100 from deforming in its axial direction to a certain extent, which helps to improve the stiffness of the shock-absorbing ring 100, further ensure the shock-proof effect of the shock-absorbing ring 100, and extend the service life of the shock-absorbing ring 100.

[0052] Reference Figures 2 to 6In one embodiment, the first elastic bracket includes a plurality of first support portions 21, each of the first support portions 21 is arranged at intervals along the circumferential direction, and two adjacent first support portions 21 are connected by the second elastic bracket, wherein the first support portion 21 extends along the circumference of the shock-absorbing ring 100 to form a large arc segment, which can not only adapt to the bending degree of the ring body 10, but also increase the connection area with the ring body 10, thereby improving the connection strength between the bracket 20 and the ring body 10. At the same time, the first support portion 21 is deformable, and its elastic modulus is greater than the elastic modulus of the ring body 10, ensuring that the bracket 20 can provide radial support force to the ring body 10 and absorb the radial force transmitted from the ring body 10 to the bracket 20.

[0053] In addition, a second elastic bracket is connected between two adjacent first support parts to form a closed loop as a whole, which facilitates the transmission of force, improves the shock absorption effect of the bracket 20, and is also convenient for the closed loop to be assembled into the ring body 10, thereby improving the assembly convenience. At the same time, compared with the first support parts 21 connected end to end to form a full circle structure, the elasticity of the second elastic bracket is further utilized to improve the overall elasticity of the shock-absorbing ring 100, which helps to extend the service life of the shock-absorbing ring 100.

[0054] Furthermore, in one embodiment, the second elastic bracket includes a second support portion 23 and two adapter portions 23, and the second support portion 23 is connected to the first support portion 21 through the adapter portion 22. It can be understood that the first support portion 21 and the second support portion 23 are distributed along the radial direction of the shock-absorbing ring 100, and the second support portion 23 and the first support portion 21 extend along the circumferential direction of the shock-absorbing ring 100 to form a large arc segment. The adapter portion 22 is located between the first support portion 21 and the second support portion 23, and serves as a connecting beam to connect the first support portion 21 and the second support portion 23 to realize the connection between the first elastic bracket and the second elastic bracket, which helps to transmit force, enhance the shockproof effect, reduce the number of parts, facilitate the subsequent covering operation of the ring body 10, and improve the manufacturing efficiency of the shock-absorbing ring 100.

[0055] By setting the second support portion 23, the support effect of the bracket 20 on the shock-absorbing ring 100 is further improved, the deformation of the shock-absorbing ring 100 in the radial direction is reduced, and the shock-absorbing ring 100 is ensured to play a shock-absorbing role between the motor 1000 and the fan housing. At the same time, the second support portion 23 is located on the outer ring of the first support portion 21, that is, the second support portion 23 is located on the side of the first support portion 21 away from the center of the shock-absorbing ring 100, and the connection of the adapter 22, or the second support portion 23 is located on the inner ring of the first support portion 21, that is, the second support portion The support portion 23 is located on one side of the first support portion 21 near the center of the shock-absorbing ring 100, and is connected to the adapter portion 22. When the shock-absorbing ring 100 is subjected to radial force, the deformation of the adapter portion 22 and the second support portion 23 can be used to enhance the buffering force because the structure available for deformation between the two adjacent first support portions 21 increases. This reliably buffers the radial force transmitted by the first support portion 21 or the second support portion 23, improves the shock absorption effect, reduces the possibility of vibration being transmitted to the fan housing, achieves the purpose of noise reduction, and improves the user experience. It should be noted that, while ensuring that the first support portion 21 and the second support portion 23 support the ring body 10, the large arc segment can include at least one arc.

[0056] In order to improve the axial stiffness of the shock-absorbing ring 100, in one embodiment, in the axial direction of the shock-absorbing ring 100, the height of the first support portion 21 is h1, and the height of the second support portion 23 is h2, h2>h1. In this way, the second support portion 23 has a larger support surface to ensure the radial support of the shock-absorbing ring 100 by the bracket 20 and the connection between the bracket 20 and the ring body 10. At the same time, by making the height of the first support portion 21 lower than the height of the second support portion 23, at this time, Figure 5 As shown, in the axial direction of the shock-absorbing ring 100, with the end face of the shock-absorbing ring 100 as the reference plane, the distance from one side of the first support part 21 to the end face is greater than the distance from the same side of the second support part 23 to the end face, which can make the flexible material near the first support part 21 larger than the flexible material near the second support part 23. Compared with the setting of the first support part 21 and the second support part 23 at the same height, the shock-absorbing ring 100 is ensured to have good elasticity, and because the first support part 21 has a certain height, it can play the role of axial support to a certain extent, effectively reducing the risk of structural failure of the shock-absorbing ring 100 due to axial force.

[0057] Furthermore, in one embodiment, in the axial direction of the shock-absorbing ring 100, the height of the first support portion 21 is h1, and the height of the adapter portion 22 is h3, where h3 ≥ h1, thereby ensuring the elasticity of the shock-absorbing ring 100 and reducing the possibility of axial deformation of the shock-absorbing ring 100, thereby helping to extend the service life of the shock-absorbing ring 100 and improve the shock-absorbing effect of the shock-absorbing ring 100. Specifically, when the height of the adapter portion 22 is too small, that is, h3 < h1, it is easy for the adapter portion 22 to crack or even break due to the force exceeding the bearing limit, thereby interrupting the transmission of force, failing to achieve a reliable connection between the first support portion 21 and the second support portion 23, and failing to enhance the buffering force through reliable deformation, thereby affecting the shock-absorbing effect of the shock-absorbing ring 100.

[0058] In addition, since h2>h1, the height of the adapter part 22 needs to satisfy: h3<h2, to avoid the adapter part 22 having a height greater than or equal to the height of the second support part 23, which would weaken the deformation ability of the adapter part 22 and easily increase the total weight of the bracket 20 and increase the cost.

[0059] Alternatively, as Figure 4 and Figure 6 As shown, in the radial direction of the shock-absorbing ring 100, the projection of the first support portion 21 and the projection of the second support portion 23 at least partially overlap. It can be understood that the first support portion 21 and the second support portion 23 can achieve at least partial overlap of the projections in the radial direction of the shock-absorbing ring 100. Specifically, because the two ends of the second support portion 23 are respectively connected to a first support portion 21, in one embodiment, the radial projection of the second support portion 23 is only arranged to overlap with one first support portion 21; in another embodiment, the radial projection of the second support portion 23 is arranged to overlap with the two first support portions 21. In this way, when the end of the first support portion 21 and the end of the second support portion 23 are connected by the adapter portion 22, the overall length of the adapter portion 22 can be extended, which helps to improve the shock-proof effect of the shock-absorbing ring 100.

[0060] Specifically, when the radial projections of the first support portion 21 and the second support portion 23 overlap, the first support portion 21, the transition portion 22 and the second support portion 23 are connected and can form, for example Figure 4 The structure framed in FIG. 1 is approximately triangularly symmetrical, which not only improves the overall stability of the bracket 20 and ensures the radial strength of the shock-absorbing ring 100, but also increases the elasticity of the bracket 20, thereby improving the shock-absorbing performance of the shock-absorbing ring 100. Of course, in other embodiments, the radial projections of the first support portion 21 and the second support portion 23 do not overlap.

[0061] Combined with reference Figure 2 and Figure 4In one embodiment, the transition portion 22 includes a first transition segment 221 and a second transition segment 222. The first transition segment 221 extends along the circumference of the ring body 10, and both ends thereof are connected to the second transition segment 222. The two second transition segments 222 are respectively connected to the first support portion 21 and the second support portion 23. The first transition segment 221 extends along the circumference of the ring body 10, so that the first transition segment 221 adapts to the curvature of the ring body 10, which helps to enhance the elasticity of the first transition segment 221 and facilitates the first transition segment 221 to pass through the two second transition segments. The connecting section 222 connects the first supporting portion 21 and the second supporting portion 23 respectively; a second transition section 222 is smoothly connected to the first transition section 221 and the first supporting portion 21, and another second transition section 222 is smoothly connected to the first transition section 221 and the second supporting portion 23, ensuring the reliable deformation of the transition section 22, and forming an active gap between the transition section 22 and the first supporting portion 21, and between the transition section 22 and the second supporting portion 23, reducing the deformation dead zone, thereby improving the elasticity and service life of the bracket 20; the second transition section 222 can be configured as an overall curved arc segment, such as Figure 4 and Figure 6 As shown, the protruding directions of the two second transition sections 222 are opposite, and can also be configured to include a straight section and two arc sections arranged at both ends of the straight section, both of which can ensure the smooth connection of various parts on the bracket 20, improve the deformation reliability of the transition part 22, and reduce the risk of breakage.

[0062] Combined with reference Figures 1 to 4 In one embodiment, the bracket 20 further includes a positioning portion 24, and the positioning portion 24 is connected to either the first support portion 21 or the second support portion 23. In the process of processing and manufacturing the shock-absorbing ring 100, the positioning portion 24 can be used to position the ring body 10 reasonably and quickly wrap the bracket 20, and the convenience of assembling the shock-absorbing ring 100 to the motor 1000 can be improved.

[0063] According to the specific size requirements and processing difficulty of the shock-absorbing ring 100, the positioning portion 24 can be set on the first support portion 21 or the second support portion 23, and can also be selectively connected to the side of the first support portion 21 or the second support portion 23 away from the center of the shock-absorbing ring 100, or can also be selectively connected to the side of the first support portion 21 or the second support portion 23 facing the center of the shock-absorbing ring 100. In other embodiments, such as Figure 6 As shown, the bracket 20 is not provided with a positioning portion 24 , or both the first supporting portion 21 and the second supporting portion 23 are provided with a positioning portion 24 .

[0064] In the circumferential direction of the shock absorbing ring 100, the first support portions 21 are arranged at intervals so that there is an avoidance gap between two adjacent first support portions 21. Figure 3 and Figure 4 In one embodiment, the positioning portion 24 is provided on the second support portion 23 and is arranged corresponding to the avoidance gap. The positioning portion 24 can be located within the avoidance gap, can be arranged close to the avoidance gap, or can even pass through the avoidance gap and approach the center of the shock-absorbing ring 100. In this way, the avoidance gap between two adjacent first support portions 21 is rationally utilized to achieve a compact design of the positioning portion 24 and the first support portion 21, effectively improving the miniaturization level of the bracket 20. At the same time, the positioning portion 24 and the first support portion 21 are effectively avoided from interfering with each other during deformation. Of course, in other embodiments, the positioning portion 24 is provided on the first support portion 21 and is arranged corresponding to the avoidance gap between two adjacent second support portions 23; or, the positioning portion 24 is provided on the second support portion 23 and is arranged on the side of the second support portion 23 away from the center of the shock-absorbing ring 100; or, the positioning portion 24 is provided on the first support portion 21 and is arranged on the side of the first support portion 21 facing the center of the shock-absorbing ring 100.

[0065] Optionally, in one embodiment, a reinforcement groove 231 is formed on the second support portion 23 corresponding to the positioning portion 24, and the recessed direction of the reinforcement groove 231 is the recessed direction toward the center of the shock-absorbing ring 100, thereby effectively increasing the effective connection area between the second support portion 23 and the ring body 10, and improving the connection strength between the bracket 20 and the ring body 10. In addition, the second support portion 23 can be thinned, the elasticity of the second support portion 23 can be enhanced, and the energy absorption and buffering capacity of the bracket 20 can be improved, which helps to improve the service life and shockproof effect of the shock-absorbing ring 100.

[0066] Specifically, a first positioning hole 241 is provided on the positioning portion 24, and a second positioning hole 11 is provided on the ring body 10 to dock with the first positioning hole 241. The first positioning hole 241 is used to perform positioning on the processing equipment to complete the covering operation of the ring body 10 on the bracket 20. In addition, a second positioning hole 11 coaxial with the first positioning hole 241 can be formed on the ring body 10 to facilitate the assembly of the shock absorber ring 100 on the motor 1000.

[0067] Furthermore, in one embodiment, the aperture of the first positioning hole 241 is d1, and the aperture of the second positioning hole 11 is d2, d1≤d2, effectively avoiding the situation where the ring body 10 is deformed due to d1>d2, ensuring that the shock-absorbing ring 100 has good shock-proof performance. Specifically, when d1<d2, part of the first positioning portion 24 is exposed through the second positioning hole 11. At this time, the setting of the first positioning hole 241 and the second positioning hole 11 forms a countersunk hole on the shock-absorbing ring 100. When d1=d2, because the first positioning hole 241 and the second positioning hole 11 are coaxial and have the same diameter, the ring body 10 completely covers the outer surface of the bracket 20, further protecting the bracket 20.

[0068] In order to ensure the reliable assembly of the shock-absorbing ring 100 on the fan, in one embodiment, the shock-absorbing ring 100 also includes a hoop 30, which is arranged on the outer periphery of the ring body 10. Furthermore, after the motor 1000 is assembled on the fan, the hoop 30 can abut against the fan and play a supporting role, reducing the influence of the force transmitted from the fan casing to the shock-absorbing ring 100 on the ring body 10 and the bracket 20, thereby ensuring the normal operation of the shock-absorbing ring 100 and extending the service life of the shock-absorbing ring 100.

[0069] Furthermore, if Figure 5 As shown, in one embodiment, in the axial direction of the shock-absorbing ring 100, the thickness of the hoop 30 is less than the thickness of the ring body 10. It can be understood that compared with the hoop 30 completely wrapping the ring body 10, the setting of the hoop 30 having a thickness less than the thickness of the ring body 10 can reduce the overall weight of the shock-absorbing ring 100. In the present application, due to the limitation that the height of the second support portion 23 is greater than the height of the first support portion 21, and in order to avoid the elasticity of the ring body 10 corresponding to the second support portion 23 in the axial direction being too small, by limiting the thickness of the hoop 30 to be less than the thickness of the ring body 10, that is, in the shock-absorbing In the axial direction of the shock ring 100, the thickness of the ring body 10 is s1, and the thickness of the hoop 30 is s2, and they satisfy: s1>s2, which can not only enable the hoop 30 to play a supporting role, but also ensure that the second support part 23 of the bracket 20 is covered with a certain thickness of the ring body 10, thereby reducing the possibility of the second support part 23 exposing the shock-absorbing ring 100, and improving the protection effect of the ring body 10 on the second support part 23. At the same time, when the second support part 23 is subjected to force, the ring body 10 at the second support part 23 can provide effective energy absorption and buffering, thereby improving the shockproof effect and service life of the shock-absorbing ring 100.

[0070] Combined with reference Figure 5 and Figure 7 In one embodiment, a mounting protrusion 12 is provided on the outer periphery of the ring body 10, and a mounting groove 31 is provided on the hoop 30 to cooperate with the mounting protrusion 12, which can increase the effective connection area between the ring body 10 and the hoop 30, thereby improving the connection strength between the ring body 10 and the hoop 30. Furthermore, two mounting protrusions 12 are provided at intervals on the outer periphery of the ring body 10, and two mounting grooves 31 are provided on the hoop 30 to cooperate with the two mounting protrusions 12. Furthermore, a support groove is formed on the outer surface of the hoop 30 facing away from the ring body 10, and the support groove can be used for the structure abutting against the shock-absorbing ring 100 to be inserted, thereby increasing the connection area between the shock-absorbing ring 100 and the structure, and improving the assembly stability of the motor 1000.

[0071] Furthermore, the end surface of the ring body 10 is provided with a connecting protrusion 13, which is used to connect to the end cover 200 of the motor 1000. This increases the connection area between the shock-absorbing ring 100 and the motor 1000, helping to improve the assembly convenience and stability of the shock-absorbing ring 100. In addition, the connecting protrusion 13 and the end surface of the ring body 10 form an assembly step, which adapts to the structure of the end cover 200 and reduces the deviation of the shock-absorbing ring 100.

[0072] Optionally, in one embodiment, the bracket 20 is a plastic component. This provides high elasticity and hardness, facilitating its support function. It also deforms to assist in energy absorption, thereby extending the service life of the shock-absorbing ring 100. Furthermore, compared to steel, this component is less expensive, lighter, and quicker to manufacture. Of course, in other embodiments, the bracket 20 can also be made of rubber, as long as its hardness is greater than that of the ring body 10. Furthermore, the hoop 30 can be configured as a plastic component, effectively preventing oxidation and rusting, thereby extending its service life.

[0073] Optionally, in one embodiment, the bracket 20 is an integrated piece, which reduces the number of parts and facilitates the subsequent covering operation of the ring body 10 , thereby improving the manufacturing efficiency of the shock-absorbing ring 100 .

[0074] Optionally, in one embodiment, the ring body 10 and the bracket 20 are injection-molded integral parts; the ring body 10 is a rubber part, and the bracket 20 is wrapped with injection-molded rubber, so that the ring body 10 and the bracket 20 are fixed as a whole, thereby facilitating the assembly of the ring body 10 and the bracket 20 on the motor 1000, thereby improving the assembly efficiency of the shock-absorbing ring 100.
