[0014] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0015] The specific technical solution of this utility model is as follows: like Figures 1 to 3 As shown, a fan frame with a rubber-coated shock-absorbing structure includes a square fan frame 1 and a shock-absorbing rubber layer 2. The square fan frame 1 has positioning rubber grooves 3 on its outer sides. The four corners of the square fan frame 1 are respectively provided with axial through holes 4. The shock-absorbing rubber layer 2 is partially surrounded on the four sides and the upper and lower edges of the square fan frame 1. The upper and lower shock-absorbing rubber layers 2 of the square fan frame 1 are connected through the axial through holes 4. The inner surface of the shock-absorbing rubber layer 2 is provided with positioning rubber blocks (not shown in the figure) that fit into the positioning rubber grooves 3. The outer side of the shock-absorbing rubber layer 2 is provided with shock-absorbing rubber parts 7 and symmetrical mounting rubber parts 5.

[0016] The aforementioned mounting adhesive part 5 includes a first adhesive strip 51 and a second adhesive strip 52. A deformation gap 54 is left between the first adhesive strip 51 and the second adhesive strip 52. The interior of the first adhesive strip 51 and the second adhesive strip 52 is provided with a gradually tapering clamping groove 53. Specifically, when the fan frame with the rubber-coated shock-absorbing structure is installed, the mounting part can be inserted into the clamping groove 53 of the first adhesive strip 51 and the second adhesive strip 52, thereby realizing the fixed installation of the fan frame with the rubber-coated shock-absorbing structure.

[0017] The square fan frame 1 is provided with a wire groove 6 on one side, and the shock-absorbing rubber layer 2 is provided with an opening 61 that matches the wire groove 6; specifically, the wire groove 6 and the opening 61 facilitate the connection of the wire to the fan motor (not shown in the figure) inside the square fan frame 1.

[0018] The aforementioned shock-absorbing rubber part 7 is in the shape of a strip or a ring.

[0019] The aforementioned square fan frame 1 has a mounting base 8 located in the middle of its interior. The mounting base 8 is fixedly connected to the square fan frame 1 by an arc-shaped rod 81. Specifically, the mounting base 8 is used to mount the fan motor (not shown in the figure) and the fan blades (not shown in the figure).

[0020] The aforementioned shock-absorbing rubber layer 2 is higher than the upper and lower surfaces of the square fan frame 1; specifically, it increases the distance between the cooling fan and the radiator fixing point, which can reduce the vibration transmission of the contact area.

[0021] The square fan frame 1 is coated by adhesive injection molding in the coating mold, so that the shock-absorbing rubber layer 2 partially surrounds the four sides and the top and bottom edges of the square fan frame 1, and an opening 61 corresponding to the wire groove 6 is left on the shock-absorbing rubber layer 2. During the adhesive injection process, the shock-absorbing adhesive layers 2 on the upper and lower surfaces of the square fan frame 1 are connected through the axial through hole 4. The inner surface of the shock-absorbing adhesive layer 2 forms a positioning adhesive block (not shown in the figure) which fills the positioning adhesive groove 3, thereby improving the connection stability between the shock-absorbing adhesive layer 2 and the square fan frame 1. The mounting adhesive part 5 for fixing and connecting the outer shell and the shock-absorbing adhesive part 7 for buffering and shock absorption are integrally formed on the outer surface of the shock-absorbing adhesive layer 2.

[0022] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
