DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0039] In addition, the present application may repeat reference numbers and / or reference letters in different examples, and such repetition is for the purpose of simplicity and clarity, and does not in itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the present application provides various specific examples of processes and materials, but those of ordinary skill in the art may recognize the application of other processes and / or the use of other materials.

[0040] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 In a first aspect of the present application, a vibration reduction structure is provided, including: a connecting portion 20 and at least two first vibration reduction portions 10. The at least two first vibration reduction portions 10 are arranged in parallel and spaced apart, and two adjacent first vibration reduction portions 10 are connected by the connecting portion 20 to form a blind groove 30.

[0041] See also Figure 8 Since at least two first vibration damping parts 10 are arranged in parallel and spaced apart, and two adjacent first vibration damping parts 10 are connected by the connecting part 20 to form the blind groove 30, at least two vibration damping parts can be arranged between the fan 80 and the housing 70, so that two of the at least two vibration damping parts are in contact with the fan 80 and the housing 70 respectively, and the vibration generated when the fan 80 is working can be transmitted and absorbed layer by layer, thereby reducing the vibration that can be transmitted to the housing 70, and the vibration damping effect is good, which improves the user experience. At the same time, the connecting part 20 connects the two adjacent first vibration damping parts 10, which can ensure the structural strength of the vibration damping structure 100, so that the vibration generated when the fan 80 is working can be transmitted between the at least two first vibration damping parts 10, so that the at least two first vibration damping parts 10 are involved in the vibration damping process, ensuring that the at least two first vibration damping parts 10 can play a role in vibration damping, and further improving the vibration damping effect.

[0042] In some embodiments, compared with the integral vibration damping structure 100, under the condition of selecting the same hard material, due to the presence of the blind groove 30, the thickness of the vibration damping structure 100 can be reduced, that is, the distance between two adjacent first vibration damping parts 10 can be reduced, and the vibration damping structure 100 of the present application can also achieve the same vibration damping effect as the integral vibration damping structure, and the space occupied by the vibration damping structure 100 can be reduced, which is convenient for layout and installation.

[0043] In some embodiments, in order to achieve vibration reduction, the vibration reduction structure 100 may be made of rubber, foam or plastic.

[0044] See also Figure 1 , Figure 2 , Figure 3 and Figure 8 In some embodiments, in order to further ensure the structural strength of the vibration reduction structure 100, the vibration reduction structure 100 further includes: a plurality of reinforcing parts 40. The plurality of reinforcing parts 40 are arranged in parallel and spaced in the blind groove 30, and are connected to the connecting part 20 and the two first vibration reduction parts 10. The structural strength of the vibration reduction structure 100 can be ensured by the plurality of reinforcing parts 40, so that the vibration generated by the fan 80 when working can be fully transmitted between at least two first vibration reduction parts 10, so that at least two first vibration reduction parts 10 are involved in the vibration reduction process, ensuring that at least two first vibration reduction parts 10 can play a role in vibration reduction, and further improving the vibration reduction effect.

[0045] In some embodiments, in order to further ensure the structural strength of the vibration reduction structure 100, when the number of blind slots 30 is two or more, the multiple reinforcement parts 40 in adjacent blind slots 30 are arranged in an alternating manner, that is, the reinforcement part 40 in one blind slot 30 of the adjacent blind slots 30 is located between the two reinforcement parts 40 in another blind slot 30, so that the vibration generated by the fan 80 when working can be fully transmitted between at least two first vibration reduction parts 10, so that at least two first vibration reduction parts 10 are involved in the vibration reduction process, ensuring that at least two first vibration reduction parts 10 can play a vibration reduction role, and further improving the vibration reduction effect.

[0046] In some embodiments, in order to ensure the stability of the connection between the connecting portion 20, at least two first vibration damping portions 10 and multiple reinforcement portions 40, the connecting portion 20, at least two first vibration damping portions 10 and multiple reinforcement portions 40 are integrally formed, which also reduces the processing cost.

[0047] See also Figure 3 and Figure 8 In some embodiments, in order to further ensure the structural strength of the vibration reduction structure 100, the height of the reinforcement portion 40 is consistent with the depth of the blind groove 30, so that the vibration generated by the fan 80 when working can be fully transmitted between at least two first vibration reduction portions 10, thereby ensuring the vibration reduction effect.

[0048] See also Figure 3 and Figure 7 In some embodiments, in order to form the blind groove 30, the connecting portion 20 is connected to the ends of two adjacent first vibration damping portions 10. Of course, in some other embodiments, the connecting portion 20 can be connected to the middle of two adjacent first vibration damping portions 10, and the blind groove 30 can also be formed.

[0049] In some embodiments, in order to ensure that the first vibration damping part 10 is in full contact with the fan 80 and the housing 70, the first vibration damping part 10 has a contact surface, and the contact surface is a plane, a curved surface or an arc surface, that is, the contact surface is a smooth and continuous surface, which increases the contact area between the first vibration damping part 10 and the fan 80 and the housing 70, so that the first vibration damping part 10 can evenly bear the vibration impact force generated during the operation of the fan 80, thereby achieving a good vibration damping effect and improving the user experience.

[0050] In some embodiments, when the vibration damping structure 100 is annular and the number of the first vibration damping parts 10 is multiple, the multiple first vibration damping parts 10 are arranged at radial intervals along the vibration damping structure 100, and the end surface of the innermost first vibration damping part 10 facing the fan 80 and the end surface of the outermost first vibration damping part 10 facing the shell 70 can be contact surfaces.

[0051] See also Figure 1 , Figure 3 and Figure 8 In some embodiments, in order to further achieve vibration reduction, the vibration reduction structure 100 further includes: a second vibration reduction part 50. The second vibration reduction part 50 is connected to one of the first vibration reduction part 10 and the connecting part 20. The second vibration reduction part 50 has a support surface 501 that is staggered from the first vibration reduction part 10 and the connecting part 20.

[0052] In some embodiments, the second vibration damping portion 50 can be disposed between the bottom of the fan 80 and the bottom of the housing 70. The bottom of the fan 80 can be disposed on the support surface 501. The fan 80 is supported by the support surface 501. The second vibration damping portion 50 is in contact with the fan 80 and the housing 70. The vibration generated when the fan 80 is working can be transmitted and absorbed, thereby reducing the vibration that can be transmitted to the housing 70. The vibration damping effect is good, thereby improving the user experience.

[0053] See also Figure 3 , Figure 5 and Figure 8 In some embodiments, in order to further achieve vibration reduction, the vibration reduction structure 100 further includes: at least two third vibration reduction parts 60. The at least two third vibration reduction parts 60 are arranged in parallel and spaced apart, and connected to the end of the second vibration reduction part 50 away from the support surface 501.

[0054] In some embodiments, the second vibration reduction part 50 is supported by at least two third vibration reduction parts 60, so that the stability of the support surface 501 supporting the fan 80 can be ensured. At the same time, the second vibration reduction part 50 can transfer the vibration generated by the fan 80 when it is working to the third vibration reduction part 60. The second vibration reduction part 50 and the third vibration reduction part 60 realize layer-by-layer transmission and absorption of the vibration generated by the fan 80 when it is working, and reduce the vibration that can be transmitted to the housing 70. The vibration reduction effect is good and the user experience is improved. Since at least two third vibration reduction parts 60 are arranged in parallel and spaced apart, not only can the force of the material be reduced and the cost be reduced, but also the vibration generated by the fan 80 when it is working can be transmitted between at least two third vibration reduction parts 60, so that at least two third vibration reduction parts 60 are involved in the vibration reduction process, ensuring that at least two third vibration reduction parts 60 can play a role in vibration reduction, and further improving the vibration reduction effect.

At the same time, the connecting part 20 connects the two adjacent first vibration reduction parts 10, which can ensure the structural strength of the vibration reduction structure 100, so that the vibration generated by the fan 80 when it is working can be transmitted between the at least two first vibration reduction parts 10, so that the at least two first vibration reduction parts 10 are involved in the vibration reduction process, ensuring that the at least two first vibration reduction parts 10 can play a role in vibration reduction, and further improving the vibration reduction effect.
