Abstract

A shock-absorbing fan housing includes an outer frame, an inner bearing, and four supporting ribs. The outer frame includes four frame corner segments and four frame frame segments. Two ends of each frame segment are respectively connected to two adjacent frame corner segments. Each support rib includes a base portion connected to the inner socket and with a tapered cross-sectional area in a direction away from the inner socket, and a rib extending outward from the base portion and connected to one of the frame corner segments department. The design of the support rib directly connecting the frame corner section can reduce the transmission path of vibration, and the design of the base part surrounding the inner bearing seat can make any two adjacent base parts connect and form a direction toward the other side. The shock-absorbing arc surface of the outer frame can effectively absorb and suppress the vibration generated when the fan blade rotates, so as to achieve the effect of suppressing the shock without adding other shock-absorbing components.

technical field

The utility model relates to a shell seat, in particular to a shell seat of a cooling fan.

Background technique

Referring to FIG. 1 , a cooling fan is often installed in a computer, an electronic device or a mechanical device, and the fan blade rotates to drive air to flow, so as to achieve the effect of heat dissipation. In a general cooling fan, the fan and the motor are installed on the fan housing 1 . As shown in FIG. 1 , a common fan housing 1 includes an outer frame 11 surrounding a setting space 111 , an inner socket 12 located in the setting space 111 , and four strips extending from the outer peripheral surface of the inner socket 12 . The tangential direction extends to connect the support ribs 13 of the outer frame 11 . The outer frame 11 includes four frame corner segments 112 arranged at equal angular intervals from each other, and four frame frame segments 113 staggered with the frame corner segments 112 . Two ends of each frame segment 113 are respectively connected to two adjacent frame corner segments 112 . Each frame corner section 112 is provided with an opening 114 through which a screw (not shown in the figure) passes. Two ends of each support rib 13 are respectively connected to the inner bearing seat 12 and the frame segment 113 .

Since the support ribs 13 are connected to the frame section 113 , when the fan blade rotates, the vibration generated by the fan blades will be transmitted to the frame section 113 along the support ribs 13 first, and then to the frame corner sections. 112 is transmitted to the installation plane through the screws passing through the openings 114. Since the vibration conduction path is far away and almost covers the entire outer frame 11, the vibration of the fan housing 1 is large, and In addition, there is no other structural design that can improve the shock absorption and damping capability. Therefore, if the user wants to improve the vibration situation, other shock absorbing components must be additionally installed on the fan housing 1 .

Detailed ways

The present utility model will be described in detail below with reference to the accompanying drawings and embodiments.

Referring to FIG. 2 , FIG. 3 , and FIG. 4 , an embodiment of the shock-absorbing fan housing of the present invention includes an outer frame 2 surrounding a setting space 20 , and an inner bearing seat located in the setting space 20 3. Four support ribs 4 extending radially outward from the inner socket 3 to connect the outer frame 2 , and four embedded parts 5 respectively embedded in the support ribs 4 . The outer frame 2 includes four frame corner segments 21 arranged at equal angular intervals, and four frame frame segments 22 staggered with the frame corner segments 21 . In this embodiment, the outer frame 2 is substantially square, and the corner segments 21 are located at four corners of the square. Each corner segment 21 forms two thicknesses along the outer frame 2 .
