In the present invention, the number of the first screws 51 and the corresponding first through holes 218 is not limited to the number of the present embodiment.

Please refer to fig. 5, which is a schematic perspective view of the bottom plate 2 shown in fig. 4. As shown in the figure, the side wall 214 of the bottom plate 2 extends from the second surface 212 of the first body 21 toward the panel 4, that is, the periphery of the first body 21 is bent toward the second surface 212 to form a continuous side wall 214, and the bent side wall 214 of the metal plate can increase the structural strength of the bottom plate 2. In some embodiments, the four sidewalls 214 may also extend in opposite directions. The second surface 212 of the first body 21 and the continuous sidewall 214 of the bottom plate 2 define a first body groove 216, the first body groove 216 is connected to the first mounting hole 22, and the sidewall 214 surrounds the first body groove 216. Referring to fig. 4, the first extension line m and the second extension line s intersect to form four blocks, and each block forms an arc wall 215 with a corresponding sidewall 214. In fig. 4, the arc-shaped wall surface 215 is formed by the corresponding side wall 214 being recessed toward the first mounting hole 22.

Please refer to fig. 6, which is a perspective view of the bracket pillar 3 of the fan bracket 1 shown in fig. 1. As shown, only a single cradle post 3 is shown in fig. 6 for ease of illustrating the structural features of the cradle post 3. The first end face 31, the second end face 32 and the three connecting walls 33 of the support pillar 3 define a space with an opening 34, which means that each support pillar 3 is a hollow structure with an opening 34, and the three connecting walls 33 of the support pillar 3 are formed by bending a metal plate, so that the support pillar has better structural strength. The support pillar 3 can be regarded as a long hexahedron, two opposite surfaces of the long end are the first end surface 31 and the second end surface 32, one of the four surfaces between the first end surface 31 and the second end surface 32 forms the opening 34, and the other three surfaces are the connecting walls 33. The first end face 31 is provided with a first screw hole 311, and the second end face 32 is provided with a second screw hole 321, which are respectively connected with the bottom plate 2 and the panel 4. The thickness of the material around the first screw hole 311 and the second screw hole 321 may be thicker than the thickness of the connecting wall 33 to improve the structural strength.

Please refer to fig. 7, which is a schematic perspective view of the panel 4 of the fan bracket 1 shown in fig. 1. As shown in the figure, the second body 41 of the panel 4 is an integrally formed structure formed by stamping a metal plate, and the second body 41 is rectangular, and four outer wall surfaces 414 formed on each side of the rectangle surround the outer periphery of the second body 41. The outer wall 414 of the panel 4 is an extension structure formed by bending the periphery of the metal plate, that is, the outer periphery of the second body 41 of the panel 4 extends toward the bottom plate 2. Due to the stamping method, any two adjacent outer walls 414 are not connected to each other. The inner wall surface 413 of the second body 41 is formed on the periphery of the second mounting hole 42, and is configured such that the periphery of the second mounting hole 42 extends in the direction toward the bottom plate 2. The inner wall 413 is also formed by bending a metal plate to enhance the structural strength of the periphery of the second mounting hole 42. The first surface 411, the inner wall 413 and the four outer walls 414 of the second body 41 together define a second body groove 415, wherein the space of the second body groove 415 is communicated with the second mounting hole 42. The bending structure among the first face 411, the inner wall face 413 and the four outer wall faces 414 of the second body 41 can increase the structural strength of the panel 4.

Referring to fig. 7, the four installation portions 416 on the second body 41 are formed by a concave method, and further, the installation portions 416 can be formed together when the second body 41 is formed by a metal plate material through a pressing method. And four installation parts 416 are disposed around the second mounting hole 42, and each installation part 416 is further adjacent to between two adjacent outer wall surfaces 414 of the second body 41. Under the consideration that the metal plates have substantially the same thickness, each of the disposing portions 416 is recessed from the second surface 412 of the second body 41, so that the disposing portion 416 protrudes from the first surface 411 of the second body 41, and the subsequent second end surface 32 of the corresponding connecting bracket post 3 has a similar structural strength. The connection between the installation portion 416 of the panel 4 and the second end surface 32 of the bracket post 3 will be described below.

Referring to fig. 3 and 7, the fan bracket 1 further includes eight second screws 52. The second body 41 of the panel 4 includes eight second through holes 417, each second through hole 417 is located at a corresponding setting portion 416, and each setting portion 416 has two second through holes 417. The second end surface 32 of each support post 3 comprises two second screw holes 321, wherein the second screw hole 321 of each support post 3 is aligned with the corresponding second through hole 417 of the second body 41 of the panel 4, and each second screw 52 passes through the corresponding second through hole 417 and the corresponding second screw hole 321 from the second surface 412 of the second body 41, so as to fix the panel 4 and the support post 3 to each other. Since the installation portion 416 of the second body 41 of the panel 4 is recessed in the second surface 412 of the second body 41, when the second screw 52 passes through the corresponding second through hole 417 of the installation portion 416 from the second surface 412 of the second body 41, the second screw 52 does not protrude out of the second surface 412 of the second body 41, and the flatness of the second surface 412 of the second body 41 of the panel 4 is high. In the present invention, the number of the second screws 52 and the corresponding second through holes 417 is not limited to the number of the present embodiment.

Please refer to fig. 8, which is a top view of a panel of the fan bracket shown in fig. 1. In the present embodiment, when the fan motor is mounted on the fan bracket 1, the second mounting hole 42 of the panel 4 serves as an air inlet of the fan motor, wherein the flow direction of the airflow generated by the operation of the fan motor can be referred to as the arrow in fig. 8, and after the airflow passes through the second mounting hole 42 serving as the air inlet, the flow direction is a direction away from the axis Z, that is, the fan blade mounted in the fan bracket 1 is a centrifugal fan. In order to avoid the hollow support posts 3 disturbing the airflow flowing through the second mounting holes 42, the opening 34 of each support post 3 faces away from the axis Z, i.e. the opening 34 of each support post 3 faces away from the axis Z. Since the four installation portions 416 are disposed around the second mounting hole 42, and each installation portion 416 is further adjacent to between two adjacent outer wall surfaces 414 of the second body 41, in order to clearly illustrate the relationship between the direction of the opening 34 and the second mounting hole 42 when the support posts 3 are installed on the installation portions 416, the direction of the opening 34 of the support post 3 will be described below with reference to the relative positions between the support posts 3 installed on the four installation portions 416, and the positional relationship between the opening 34 of each support post 3 and the second mounting hole 42 can be further derived according to the relative positions between the support posts 3 installed on the four installation portions 416. In fig. 8, the bracket post 3 connected to the setting portion 416 is illustrated by a thick black line, and the four outer wall surfaces in fig. 8 are respectively defined as a first outer wall surface 414a, a second outer wall surface 414b, a third outer wall surface 414c and a fourth outer wall surface 414d, wherein the first outer wall surface 414a and the second outer wall surface 414b are disposed opposite to each other, the third outer wall surface 414c and the fourth outer wall surface 414d are disposed opposite to each other, and the third outer wall surface 414c and the fourth outer wall surface 414d are respectively located between the first outer wall surface 414a and the second outer wall surface 414 b. An installation portion between the first outer wall surface 414a and the third outer wall surface 414c, an installation portion between the third outer wall surface 414c and the second outer wall surface 414b, an installation portion between the second outer wall surface 414b and the fourth outer wall surface 414d, and an installation portion between the fourth outer wall surface 414d and the first outer wall surface 414a are defined as a first installation portion 416a, a second installation portion 416b, a third installation portion 416c, and a fourth installation portion 416d, respectively. The opening 34 of the support column 3 connected to the first setting portion 416a faces away from the support column 3 connected to the fourth setting portion 416d, the opening 34 of the support column 3 connected to the second setting portion 416b faces away from the support column 3 connected to the first setting portion 416a, the opening 34 of the support column 3 connected to the third setting portion 416c faces away from the support column 3 connected to the second setting portion 416b, and the opening 34 of the support column 3 connected to the fourth setting portion 416d faces away from the support column 3 connected to the third setting portion 416 c. As can be seen from the above, the opening 34 of each support post 3 faces away from the other support post 3, i.e. the opening 34 of each support post 3 faces away from the second mounting hole 42.

Of course, in some embodiments, the direction of the opening 34 of each support post 3 may also be changed, and it is only necessary that the opening 34 of each support post 3 faces away from the direction of the axis Z, for example, the opening 34 of the support post 3 connected to the first setting portion 416a faces away from the support post 3 connected to the second setting portion 416b, the opening 34 of the support post 3 connected to the second setting portion 416b faces away from the support post 3 connected to the third setting portion 416c, the opening 34 of the support post 3 connected to the third setting portion 416c faces away from the support post 3 connected to the fourth setting portion 416d, and the opening 34 of the support post 3 connected to the fourth setting portion 416d faces away from the support post 3 connected to the first setting portion 416 a. Thus, each of the support posts 3 has directionality when the support post 3 is disposed on the disposing portion 416 according to the direction of the opening 34, thereby achieving the effect of facilitating the airflow.

Please refer to fig. 9, which is a schematic perspective view of the fan bracket 1 shown in fig. 1 applied to accommodate a fan. As shown in the figure, the fan bracket 1 is used for accommodating the fan 6, wherein at least a portion of the fan 6 is disposed in a space formed among the bottom plate 2, the plurality of bracket posts 3 and the panel 4, the fan 6 has a fan blade 61 and a motor 62, the fan blade 61 is located in the space formed among the bottom plate 2, the plurality of bracket posts 3 and the panel 4, the fan blade 61 is adjacent to the second mounting hole 42 of the panel 4, and the second mounting hole 42 serves as an air inlet of the fan 6 when the fan blade 61 operates. The fan blades 61 are in the form of a centrifugal fan, wherein the flow direction of the airflow generated by the operation of the fan motor can be shown by the arrows in fig. 9, that is, the airflow enters the fan bracket 1 from the axial direction of the axis Z through the second mounting hole 42 and flows out of the fan bracket 1 from the radial direction of the axis Z. According to the structural characteristics of the fan bracket 1, for example, the first body 21 of the bottom plate 2 has four arc-shaped wall surfaces 215, so that the area of the first body 21 of the bottom plate 2 is small, and the airflow stability of the fan 6 accommodated in the fan bracket 1 is good. The motor 62 passes through the first mounting hole 22 through the first surface 211 of the first body 21 of the base plate 2, and the motor 62 is used for driving the fan blades 61 to rotate.

In summary, the first body of the bottom plate is an integrally formed structure formed by stamping a single metal plate, i.e. the bottom plate is a single part without welding points, and the integrally formed single part has better flatness, which is beneficial to reducing the manufacturing cost. In addition, the first end face, the second end face and the three connecting walls of the bracket column define a space with an opening, so that the space has better structural strength, and the opening of the bracket column of the fan bracket is favorable for the airflow flow of the fan, so that the airflow stability of the fan is better. In addition, according to the structural characteristics of the fan bracket, for example, the first body of the bottom plate has four arc-shaped wall surfaces, so that the area of the first body of the bottom plate is smaller, and further, the airflow stability of the fan accommodated by the fan bracket is better.
