It will be appreciated that the second fan 190 rotates to generate vibration, and the vibration can be transmitted to the connection post 111 through the second bracket 180, because the connection post 111 is in threaded connection with the chassis 110, the connection post 111 can drive the chassis 110 to resonate, but the elastic material disposed on the contact surface between the connection post 111 and the chassis 110 can counteract a part of the vibration by self deformation, so that only a tiny part of the vibration is transmitted to the chassis 110.

According to the electrical equipment 100 provided by the embodiment of the utility model, through the arrangement of the threaded connection structure and the elastic material, on one hand, the resonance between the connecting column 111 and the case 110 is small, and the vibration noise at the frequency conversion and the fundamental frequency is reduced, so that the noise of the whole equipment is reduced; on the other hand, the fastening feature is reserved on the connecting column 111, and the fastening installation can be performed by using a tool, so that the installation is convenient.

In some embodiments, as shown in fig. 21-22, the second bracket 180 may include: a base 181 and a back plate 182.

The base 181 may be coupled to the connection post 111.

As shown in fig. 17-19 and 21-22, after the back plate 182 is fixedly connected with the base 181, the second fan 190 may be mounted on a side of the back plate 182 near the base 181, and the second fan 190 may be located above the base 181.

It can be appreciated that the second fan 190 generates vibration during operation, the vibration is directly transmitted to the back plate 182 of the second bracket 180, the back plate 182 of the second bracket 180 is driven to vibrate, and the vibration is transmitted to the base 181 of the second bracket 180, because the joint edge of the base 181 is fixedly connected with the connection post 111, the connection post 111 is fixedly connected with the chassis 110, and the base 181 of the second bracket 180 drives the connection post 111 and the chassis 110 to resonate correspondingly.

According to the electrical equipment 100 provided by the embodiment of the utility model, through the base 181 and the backboard 182, the fixed connection between the second bracket 180 and the second fan 190 as well as the connection column 111 is realized, and the direct contact connection between the second fan 190 and the chassis 110 is avoided, so that the overlap area between the second fan 190 and the chassis 110 is reduced, and the noise influence caused by the resonance effect is further reduced.

In some embodiments, as shown in fig. 17-19, a fourth vibration dampening shoe 104 may be provided between the second fan 190 and the back plate 182.

According to the electrical equipment 100 provided by the embodiment of the utility model, through the arrangement of the fourth vibration reduction pad 104, on one hand, vibration generated by the operation of the second fan 190 is prevented from being transmitted to the second bracket 180, so that the structure is prevented from being driven to vibrate, and the noise of the whole equipment is further reduced; on the other hand, the impact caused by vibration is relieved, and related structural parts are protected.

In some embodiments, as shown in fig. 21-22, the base 181 may be provided with a stiffening structure 183.

It can be appreciated that during the long-term operation of the electrical apparatus 100, the second fan 190 drives the second bracket 180 to resonate frequently, and frequent resonance is accompanied by the continuous impact force on the second bracket 180, so that the stress concentration point of the second bracket 180 is prone to crack, and thus a structural instability phenomenon occurs, which causes an increase in the resonance amplitude of the second bracket 180, but the reinforcing structure 183 can improve the fatigue strength of the second bracket 180 to a certain extent, so as to reduce the resonance amplitude of the second bracket 180 more effectively.

According to the electrical equipment 100 provided by the embodiment of the utility model, through the arrangement of the reinforcement structure 183, the plasticity and toughness of the second bracket 180 are increased, the fatigue resistance of the second bracket 180 is obviously improved, and on one hand, the resonance amplitude of the second bracket 180 is reduced, so that the noise of the whole machine is reduced; on the other hand, the loss of the second bracket 180 during the operation of the apparatus is reduced, thereby extending the service life of the apparatus.
