Through setting up first space, avoid vibration noise and thermal direct transfer that motor element and lateral wall contact caused, owing to the setting in first space, drop at the host computer or under the condition that the little beat takes place for motor element at host computer operation in-process, first space provides the space for motor element's beat, thereby prevent motor element direct butt to the lateral wall of protection casing and take place hard contact, and then promote the anti of host computer, reduce motor element and the phenomenon of protection casing resonance at host computer operation in-process simultaneously, stop resonance noise, play good light-tone effect.

Through setting up the second space, avoid the motor to transmit the vibration of protection casing to further transmit to the casing again, because the serious condition of motor element beat can appear in the host computer drop test, in this case, the protection casing centers on the beat of motor to a certain extent, but if under extreme conditions, can cause the protection casing to be swayed by motor element's violent beat and take place, consequently, through setting up the second clearance, provide beat space for the protection casing, thereby reduce the potential risk that the casing is collided to the protection casing, promote the anti-drop performance of host computer, in addition, through setting up the second space, because the casing is the structure of circumference parcel protection casing, consequently, can form annular closed separate the cavity at the second space, separate the cavity and play good isolation effect to motor element's vibration noise and heat, thereby at the outgoing of noise reduction and avoid host computer to scald one's hand and the problem of having a hemp.

In addition, the present utility model is not limited to the shape of the side wall of the protective cover, and for example, any one of the following three embodiments may be adopted:

Any of the following embodiment examples 4 to 6 can be independently implemented, and can be implemented in combination with any of the above embodiment examples 1 to 3.

In embodiment 4, as shown in fig. 6 and 7, the side wall 611 of the shield case is a lower panel provided with a notch 614, and the notch 614 extends to the bottom end of the lower panel along the axial direction of the shield case.

Through being provided with the breach groove at the coaming down for the coaming down has deformation space in order to have great deformability, when the condition of coaming down is collided to the motor appears, the coaming down offsets the collision force of motor through adaptive deformation, and avoid directly being hit by the motor and break, consequently, the coaming down not only plays good righting effect to the motor, avoids the motor to further cause the damage to casing or control panel, protects self structure not to receive the destruction of motor simultaneously, makes host computer reliability promote. Through setting up the outlet in the position of coaming down, do benefit to the lead wire of motor wear out with control panel or external power source intercommunication, outlet and breach groove intercommunication make things convenient for the demolding to make, promote the ability of coaming's deformation down moreover, avoid being broken by the motor striking. Through setting up the card wire casing, prevent the pencil winding, avoid the mutual interference between the pencil and draw the back and cause the unreliable condition of connection, space utilization is reasonable compact.

Meanwhile, due to the arrangement of the first gap and the second gap, an inner annular separation cavity is formed between the lower coaming and the side of the motor assembly, and an outer annular separation cavity is formed between the lower coaming and the shell, wherein the inner annular separation cavity is communicated with the outer annular separation cavity through a notch groove, a small amount of vibration noise and heat can be transferred to the shell, but the lower coaming encloses most of the axial space of the motor assembly, so that a comprehensive protection effect is achieved; when motor assembly operates, vibration noise and heat can receive the baffle energy attenuation of coaming down mostly, only allow less part to transmit to the casing from the breach groove, noise and heat need pass through interior annular separates the cavity in proper order, outer annular separates the cavity and just pass through the external world after separating the baffle layer by layer, consequently, this embodiment example can promote the effect of host computer anti-falling performance and fall noise and cooling effect in step.

More preferably, the top of the lower coaming is provided with an outlet 615, and the outlet 615 is communicated with the notch 614; outside the notch 614 is a slot 616.

More preferably, a threading hole 121 through which a power cord connected with the control board passes is formed in the side wall of the top cover 12, an inner hole 622 corresponding to the threading hole 121 is formed in the upper coaming, the inner hole 622, the outlet 615 and the notch 614 are communicated, and a wire clamping opening 617 with an enlarged size is further formed in the bottom end of the notch 614.

Embodiment 5 this embodiment is based on embodiment 3, in which the side wall of the shield is formed of a plurality of sub-plates intermittently arranged in the circumferential direction of the motor assembly.

Through setting up a plurality of minute boards, enclose jointly to the circumference of motor element and keep off the protection, avoid motor element beat collision casing, the space between a plurality of minute boards can provide deformation space for minute board, after motor element bumps minute board, minute board can deform and come buffering atress, avoids breaking, simultaneously, has between minute board and dodges the clearance and do benefit to the arrangement and the joint of lead wire.

In this embodiment, form more between a plurality of minute boards and dodge the space, improve the host computer and fall behind, each minute board is through nimble deformation to the effect of rectifying of host computer, simultaneously, though have the space between each minute board, at the in-process of host computer operation, motor element's heat and vibration still can be reflected by minute board after transmitting each minute board, the sound wave of reflection is disordered makes energy offset each other, thereby realize better effect of making an uproar that falls, the same, the heat is cut down through the separation temperature of each minute board, thereby prevent the problem that the host computer scalds one's hand.

In embodiment 6, the side wall of the protective cover is a closed-loop annular plate extending continuously in the circumferential direction of the motor assembly, and the annular plate is provided with a through hole through which a lead wire of the motor passes.

Because the existence of annular plate, first space and second space, annular plate separates first space and second space into the interior annular of closed loop and separates the cavity with outer loop and separate the cavity, at the in-process of host computer operation, noise and heat need separate cavity, outer annular and separate the cavity through interior annular in proper order, just pass through shell and external after separating the fender layer upon layer, consequently, can have better light sound effect and prevent scalding one's hand effect, promote the use greatly and feel. The annular plate performs omnibearing centralizing protection after falling down to the host, so that the annular plate effectively prevents all parts of the circumference of the motor assembly from impacting the shell, and potential hazards of damaging the shell due to motor collision in the prior art are eliminated.
