Description

Fan frame

Technical Field

The present invention relates to a frame, and more particularly to a fan frame.

Background

Referring to fig. 1, a structure diagram of a conventional fan frame is shown. As shown in fig. 1, in order to prevent the wires 20 from being scattered and affecting the normal operation of the fan motor, the conventional fan frame 50 uses a wire arranging structure 51 to arrange the wires 20. However, the structural design of the wire arrangement groove 51S of the conventional wire arrangement structure 51 does not consider the vibration and artificial pulling of the fan motor, so that the wire 20 is often separated from the wire arrangement structure 51 due to the long-term vibration of the fan motor or the artificial pulling during the installation process, thereby affecting the normal operation of the fan motor.

Therefore, there is a need to provide an innovative and advanced fan frame to solve the above problems.

Detailed Description

In order to make the technical means of the present invention more clearly understood, the present invention may be implemented in the form of the following description, and in order to make the objects, features and advantages of the present invention more comprehensible, preferred embodiments accompanied with figures are described in detail below.

Fig. 2 is a perspective view of the structure of the fan frame of the present invention. Fig. 3 is a top view of the structure of the fan frame of the present invention. Fig. 4 is a structural side view of the fan frame of the present invention. Referring to fig. 2, 3 and 4, the fan frame 10 of the present invention includes a frame 12 and a wire arrangement structure 14.

The frame 12 has an upper end surface 12T, a lower end surface 12L, and a side wall 12S. The sidewall 12S includes a first wall 121 and a second wall 122. In the present embodiment, the second wall 122 is not connected to the first wall 121.

The wire arrangement structure 14 includes a first blocking wall 141, a second blocking wall 142, a wire arrangement groove 143, and a wire-entering inclined guide groove 144.

The first blocking wall 141 is connected to the first wall 121, and the first blocking wall 141 has an inner wall surface 141a, an outer wall surface 141b, and a first inclined end surface 141 c. The inner wall surface 141a faces the wire management groove 143, and the outer wall surface 141b faces the inner wall surface 141 a. The first inclined end face 141c is inclined in a direction from the upper end face 12T to the lower end face 12L of the housing 12, and the first inclined end face 141c may be inclined in a direction from the outer wall face 141b to the inner wall face 141 a.

In the present embodiment, a first included angle θ 1 is formed between the first inclined end surface 141c and the upper end surface 12T of the frame 12, and preferably, the first included angle θ 1 is less than or equal to 85 °. The first inclined end surface 141c and the lower end surface 12L of the housing 12 form a third angle θ 3 therebetween.

The second blocking wall 142 is connected to the second wall 122, and the second blocking wall 142 has an inner wall surface 142a, an outer wall surface 142b, and a second inclined end surface 142 c. The inner wall surface 142a faces the wire arrangement groove 143, and the outer wall surface 142b faces the inner wall surface 142 a. The second inclined end surface 142c is inclined from the upper end surface 12T of the housing 12 toward the lower end surface 12L, and the second inclined end surface 142c may be inclined from the outer wall surface 142b toward the inner wall surface 142 a.

In the present embodiment, a second included angle θ 2 is formed between the second inclined end surface 142c and the upper end surface 12T of the frame 12, preferably, the second included angle θ 2 is greater than the first included angle θ 1, and a sum of the first included angle θ 1 and the second included angle θ 2 is equal to 180 °.

Further, the second inclined end surface 142c of the second blocking wall 142 is parallel to the first inclined end surface 141c of the first blocking wall 141.

A fourth included angle θ 4 is formed between the second inclined end surface 142c and the lower end surface 12L of the frame 12, preferably, the fourth included angle θ 4 is not greater than 85 °, and the fourth included angle θ 4 is smaller than the third included angle θ 3. In addition, it is preferable that the sum of the third included angle θ 3 and the fourth included angle θ 4 is equal to 180 °.

The wire arranging groove 143 is located at one side of the first blocking wall 141 and the second blocking wall 142, and is used for accommodating the wire 20. The wire-entering inclined guide groove 144 is located between the first inclined end surface 141c of the first blocking wall 141 and the second inclined end surface 142c of the second blocking wall 142, and communicates with the wire-arranging groove 143.

Preferably, the groove width W of the wire-entering inclined guide groove 144 is less than or equal to the wire diameter D of the wire 20, so as to limit the wire 20 in the wire-arranging groove 143. In the present embodiment, the wire 20 is perpendicular to the upper end surface 12T of the frame 12, and the incoming inclined guide groove 144 intersects with the wire 20 at two points (as shown in fig. 4). Alternatively, in another embodiment, the entry chute 144 and the wire 20 may intersect at a point (not shown).

In addition, because the wire inlet inclined guide groove 144 is inclined at an angle, the wire 20 can be effectively prevented from being separated from the wire arranging groove 143 due to long-term vibration of the motor or artificial pulling. In the present embodiment, the inclination angle of the wire-entering inclined guide groove 144 can be further controlled by adjusting the first included angle θ 1, the second included angle θ 2, the third included angle θ 3 and the fourth included angle θ 4, and the larger the inclination angle of the wire-entering inclined guide groove 144 is, the lower the probability that the wire 20 is separated from the wire-arranging groove 143 is.

Although the present invention has been described with reference to a preferred embodiment, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
