In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings. It should be understood that the description is intended to be illustrative only and is not intended to limit the scope of the present invention. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.

The first embodiment is as follows: referring to fig. 1 and 2, the fan fixing mechanism 100 of the present embodiment is used for fixing a fan 200 and includes a supporting frame 110, a plurality of fixing pieces 120 and a plurality of fasteners 130.

The carrier frame 110 has a plurality of openings 111, each of the openings 111 has a first edge 112 and a second edge 113 opposite to each other in a first direction F1, and has a third edge 114 and a fourth edge 115 opposite to each other in a second direction F2 perpendicular to the first direction F1. The carrying frame 110 further has a first coupling hole 116 located near the second edge 113, and includes two first bearing walls 117 located at the third edge 114 and the fourth edge 115, respectively, and opposite to each other. In the present embodiment, the supporting frame 110 is elongated, and the plurality of openings 111 are arranged in a row, but not limited thereto.

Each fixing plate 120 includes a main plate body 121, a first position-limiting portion 122, two second position-limiting portions 123 and two second bearing walls 124. The main plate body 121 covers one of the openings 111 and is used to fix one of the fans 200. The first position-limiting portion 122 is disposed on one side of the main body 121 in the first direction F1 and adapted to abut against the first edge 112, and a second combining hole 125 corresponding to the first combining hole 116 is disposed near a side away from the side where the first position-limiting portion 122 is disposed. The two second position-limiting portions 123 are respectively disposed on two opposite sides of the main body 121 in the second direction F2 and respectively adapted to abut against the third edge 114 and the fourth edge 115 of the opening 111. The two second bearing walls 124 are respectively disposed on two opposite sides of the main body 121 in the second direction F2 and are opposite to each other, wherein the two second bearing walls 124 can be disposed between the two first bearing walls 117, and each bearing wall 124 is connected with the corresponding first bearing wall 117 in a pull fit manner. In the present embodiment, the second position-limiting portion 123 may be surrounded by the second support wall 124, but not limited thereto, for example, in other embodiments not shown, the second position-limiting portion 123 may be parallel to the second support wall 124.

The second embodiment is as follows: in this embodiment, the two second bearing walls 124 respectively include elastic pieces 127 protruding toward the first bearing wall 117 to provide the cooperation between the first bearing wall 117 and the second bearing wall 124, but not limited thereto. For example, in other embodiments not shown, the elastic piece 127 may also be disposed on the first bearing wall 117.

The third concrete embodiment: in the embodiment, when the first position-limiting portion 122 abuts against the first edge 112 and the two second position-limiting portions 123 abut against the third edge 114 and the fourth edge 115, respectively, the main body 121 can be parallel to a plane including the first direction F1 and the second direction F2, i.e., parallel to the carrying frame 110. Specifically, the supporting frame 110 has a first surface 118 and a second surface 119 opposite to each other, the first position-limiting portion 122 extends integrally from the main body 121 and is bent to abut against the first surface 118, and each of the second position-limiting portions 123 extends integrally from the main body 121 and abuts against the second surface 119. Therefore, the supporting frame 110 is clamped by the first position-limiting portion 122 and the second position-limiting portion 123.

Each of the couplers 130 is coupled to the second coupling hole 125 and the first coupling hole 116 corresponding to each other. In the embodiment, the coupling member 130 is a screw and cooperates with the nut 140 to couple the second coupling hole 125 to the first coupling hole 116, but is not limited thereto.

The fourth concrete embodiment: in the present embodiment, the main body 121 of each fixing sheet 120 has a mesh opening 1210 connected to the outside, so that the airflow of each fan 200 can enter the inside of the pv inverter (not shown).

The fifth concrete embodiment: in the present embodiment, each fan 200 is locked to the main body 121 of the fixing plate 120 by a plurality of screws 150. The screw 150 may be a self-tapping screw, but is not limited thereto.

The sixth specific embodiment: in this embodiment, each fixing sheet 120 further includes an operating portion 126 extending in a bending manner on a side of the main sheet body 121 away from the first position-limiting portion 122, so as to facilitate a user to hold the fixing sheet by hand.

Therefore, the user can hold the operation portion 126 with hand to enable the fixing sheet 120 combined with the fan 200 to approach the opening 111 from the second surface 119 of the carrying frame 110, first enable the first limiting portion 122 to abut against the first edge 112, and cover the opening 111 with the fixing sheet 120 by taking the abutting position of the first limiting portion 122 and the first edge 112 as a fulcrum, while the two second limiting portions 117 can abut against the second surface 119 of the carrying frame 110 at the third edge 114 and the fourth edge 115, and meanwhile, the two second bearing walls 124 can be disposed between the two first bearing walls 117, each bearing wall 124 is in pull fit with the corresponding first bearing wall 117, and the second combination hole 125 overlaps the first combination hole 116. Since the two second bearing walls 124 are fitted between the two first bearing walls 117, the fixing plate 120 does not easily fall off the loading frame 110, and a user can easily couple the second coupling hole 125 to the first coupling hole 116 using the coupling member 130 without holding the fixing plate 120 or the fan 200 by hand. On the other hand, when the coupler 130 is removed, the fixing sheet 120 does not fall off from the carrying frame 110, but the user only needs to push the fixing sheet 120 slightly at a position far from the first edge 112 to separate the fixing sheet 120 from the carrying frame 110.

The fan fixing mechanism of the embodiment fixes the fan on the fixing sheet, and the fixing sheet is limited on the bearing frame, so that the fixing sheet fixed with the fan can be dismounted on the bearing frame by using only one combining piece on one fixing sheet, and the fan can be conveniently dismounted.

It is to be understood that the above-described embodiments of the present invention are merely illustrative of or explaining the principles of the invention and are not to be construed as limiting the invention. Therefore, any modification, equivalent replacement, improvement and the like made without departing from the spirit and scope of the present invention should be included in the protection scope of the present invention. Further, it is intended that the appended claims cover all such variations and modifications as fall within the scope and boundaries of the appended claims or the equivalents of such scope and boundaries.
