However, since the yielding groove 100 with the front opening affects the strength and stability of the entire rear cover 10, the stabilizing members 30 are required to be disposed at the opening of the yielding groove 100, so as to connect with the rear cover 10 at the left and right sides of the yielding groove 100 through the stabilizing members 30, thereby enhancing the stability of the opening.
The conventional fixing member 30 is connected in such a manner that either one of the right and left sides is hinged to the rear cover 10, and the other side is fastened in the clamping groove 101 of the rear cover 10. The structure not only needs to be hinged and then fastened in the assembly process, but also affects the assembly efficiency. Moreover, the buckle connection has the problem that the hard plastic has aging embrittlement after long-term use to influence fracture. Moreover, in long-term use, vibration may cause a problem of collision noise. Meanwhile, when the rear cover 10 is detached, the fixing member 30 needs to be released first to enable the opening of the abdication groove 100 to pass through the bracket 20, so that the problem of damage caused by aging of hard plastic can be caused when the rear cover is detached or buckled later.

Detailed Description
The utility model is further described below with reference to the drawings and examples.
Referring to fig. 1-4, a fan back cover structure comprises a back cover 10, two abdicating grooves 100 are respectively arranged on the left and right sides of the back cover 10, the abdicating grooves 100 penetrate through the back cover 10 forwards and are arranged in front of the front end openings, a stabilizing piece 30 is arranged at the front part of each abdicating groove 100, the stabilizing piece 30 is respectively connected with the back covers 10 on the left and right sides, the stabilizing piece 30 is composed of a connecting sheet 310 and mushroom nails 320 respectively arranged on the left and right sides of the connecting sheet 310, through holes 130 are respectively arranged on the back covers 10 on the left and right sides of the front part of the abdicating grooves 100, the mushroom nails 320 are in interference insertion connection in the through holes 130, and the mushroom nails 320 are made of soft materials.
The utility model adopts the mushroom nails made of soft materials to bring the traditional buckle connection and hinged connection scheme, so that the problem that hard plastics are easy to break due to aging can be avoided, the connection stability of the connecting sheet and the rear covers on the left side and the right side of the abdication groove can be further increased due to interference insertion fit, and collision noise caused by long-term use vibration can be avoided.
