Specific implementation

[0028] In order to make those skilled in the art better understand the technical scheme of the present application, the present application will be further described in detail below with reference to the drawings.

[0029] The present application provides a kind of fan internal support plate structure as Figures 1-4 It is shown in the figure, including fan upper shell 1 and fan lower shell 2, fan upper shell 1 and fan lower shell 2 are assembled into integral fan, and both are internally installed with support assembly 3, fan upper shell 1 and fan lower shell 2 one side is air inlet 4, the other side is air outlet 5;

[0030] Specifically, the two sides of the inner wall of fan upper shell 1 and fan lower shell 2 are provided with symmetrical transverse mounting groove 6, and the middle part of the inner wall of the two is also provided with vertical mounting groove 7;

[0031] In this embodiment, fan upper shell 1 and fan lower shell 2 need to be prepared before fan assembly, the two shells will be assembled into integral fan, and the positions of air inlet 4 and air outlet 5 are determined.

[0032] Specifically, symmetrical horizontal installation grooves 6 are processed on both sides of the inner wall of the upper fan shell 1 and the lower fan shell 2, and vertical installation grooves 7 are processed in the middle of the inner wall, and the inner side of the horizontal installation groove 6 and the vertical installation groove 7 is a plane.

[0033] Specifically, for the support assembly 3, a horizontal support plate 31 and a vertical support plate 32 are prepared.

[0034] The side of the horizontal support plate 31 and the vertical support plate 32 facing the air inlet 4 is processed into a symmetrical inclined surface, and the other side is processed into a plane.

[0035] Referring to Figures 3-4 , the support assembly 3 includes a horizontal support plate 31 and a vertical support plate 32, which are respectively installed in the horizontal installation groove 6 and the vertical installation groove 7, and the other end of the vertical support plate 32 is installed at the bottom of the horizontal support plate 31 and is perpendicular to it.

[0036] Specifically, the horizontal support plate 31 and the vertical support plate 32 are both provided with installation holes 33 matched with the horizontal installation groove 6 and the vertical installation groove 7, and the upper side of the installation hole 33 of the horizontal support plate 31 is provided with a positioning slot 34, and the bottom surface of the middle part of the horizontal support plate 31 is provided with a butt joint groove 35, and the top of the vertical support plate 32 is matched with the butt joint groove 35.

[0037] In this embodiment, the horizontal support plate 31 is butt jointed with the horizontal installation groove 6 on both sides of the inner wall of the upper fan shell 1 and the lower fan shell 2 through the installation holes 33 at both ends. During the butt joint process, the horizontal support plate 31 is accurately positioned in the horizontal installation groove 6 by using the positioning slot 34, ensuring the accuracy of the installation.

[0038] Further, the vertical support plate 32 is butt jointed with the vertical installation groove 7 through the installation hole 33, and then the top of the vertical support plate 32 is matched and installed with the butt joint groove 35 at the bottom of the middle part of the horizontal support plate 31, so that the vertical support plate 32 is vertically installed at the bottom of the horizontal support plate 31.

[0039] Specifically, the top of the horizontal support plate 31 in the middle part of the butt joint groove 35 is also provided with a sunken groove 36, and the size of the sunken groove 36 is matched with the butt joint groove 35, and a plurality of symmetrical motor installation holes 37 are also provided on both sides of the sunken groove 36.

[0040] Specifically, the horizontal support plate 31 and the vertical support plate 32 are provided with a weight reduction groove 38 inside, and a plurality of support ribs 39 are arranged in the weight reduction groove 38, and the plurality of support ribs 39 are staggered.

[0041] Specifically, the side of the horizontal support plate 31 and the vertical support plate 32 facing the air inlet 4 is a symmetrical inclined surface, and the other side is a plane.

[0042] Referring toFigures 1-2 The lateral installation slot 6 and the vertical installation slot 7 are provided on the upper fan shell 1 and the lower fan shell 2, and the inner side surface is a plane.

[0043] In this embodiment, the support assembly 3 composed of the lateral support plate 31 and the vertical support plate 32 is installed inside the upper fan shell 1 and the lower fan shell 2, providing internal support for the entire fan structure. During the operation of the fan, when the fan is subjected to external vibration or internal airflow pressure, the support assembly 3 can effectively prevent the shell from deforming. For example, during high-speed operation, the pressure distribution inside the fan is uneven, and the support assembly 3 can stabilize the shell structure to ensure the normal operation of the fan.

[0044] In this embodiment, the support ribs 39 inside the lateral support plate 31 and the vertical support plate 32 are staggered in the weight-reducing groove 38. These support ribs 39 not only reduce the weight of the support plate, but also enhance the structural strength of the support plate. When the support plate is subjected to a large pressure, the support ribs 39 can disperse the stress and prevent local damage to the support plate, just like the reinforcing bars in building structures, improving the stability of the entire support structure.

[0045] In this embodiment, the positioning slot 34 at both ends of the lateral support plate 31 facilitates the installation and positioning of the lateral support plate 31 in the lateral installation slot 6. During actual installation, the operator can quickly and accurately align the lateral support plate 31 with the lateral installation slot 6 through the positioning slot 34, improving the installation efficiency.

[0046] In this embodiment, the matching structure of the butt joint groove 35 at the top of the vertical support plate 32 and the bottom surface of the middle part of the lateral support plate 31 allows the vertical support plate 32 to be accurately connected with the lateral support plate 31 during installation, reducing the adjustment time during installation and further improving the installation convenience of the entire support assembly 3.

[0047] In this embodiment, the motor installation hole 37 on both sides of the sinking groove 36 on the lateral support plate 31 provides convenience for the installation of the motor inside the fan. During the assembly of the fan, the motor can be stably installed on the lateral support plate 31, and the size of the sinking groove 36 matches the butt joint groove 35, providing a suitable space for the installation of the motor without affecting the overall structural strength of the lateral support plate 31.

[0048] In this embodiment, the inclined surface design on the side of the lateral support plate 31 and the vertical support plate 32 facing the air inlet 4 helps to optimize the airflow characteristics inside the fan. When the airflow enters the fan from the air inlet 4, the inclined surface can guide the airflow to pass through the support plate more smoothly, reducing the resistance of the airflow and improving the working efficiency of the fan. The flat surface design on the other side is also beneficial to maintaining the stability of the structure, and after the airflow passes through the support plate, the flat surface structure can make the airflow flow more smoothly to the air outlet 5.

[0049] The above has described certain exemplary embodiments of the present application by way of illustration only, and it is needless to say that the described embodiments can be modified in various ways without departing from the spirit and scope of the present application for those skilled in the art. Therefore, the above drawings and description are illustrative in nature, and should not be construed as limiting the scope of protection of the present application.
