Description

Fan assembly, support frame for supporting fan and electronic control module

Technical Field

The utility model relates to an automatically controlled field especially relates to a fan assembly, be used for supporting support frame and the electronic control module of fan.

Background

In industrial and civil electronic control modules such as frequency converters, power supplies and inverters, the electronic control modules are often equipped with fans for heat dissipation due to heat generated by electronic components in the electronic control modules. When the electronic control module works, the fan blades rotate at a high speed, and if a finger or a large object touches the fan blades, the fan is very dangerous and damaged.

In order to prevent fingers and relatively large objects from touching the fan blades, thereby causing unsafe factors or damaging the fan, a technician adds a metal shield 1 as shown in fig. 1. The metal protective cover 1 is in a net shape, and through holes in the metal protective cover 1 can play a role in heat dissipation and prevent a finger and other slightly large objects from entering the fan 2 and touching the rotating fan blades. However, since the fan frame body and the metal shield 1 are separately manufactured, the metal shield 1 needs to be fixed to the fan frame body by four bolts 3, and the fan frame body needs to be fixed to an electronic control module such as an inverter, and when the fan is disassembled, the four bolts 3 need to be disassembled one by one. Furthermore, the four bolts 3 need to fix the metal protective cover 1 on the fan frame body and fix the fan frame body on the electric control module, and the mounting holes on the electric control module can be blocked by the fan frame body, so that the installation is inconvenient.

Therefore, the conventional fan has the following disadvantages:

1) for the safety of the fan, a metal protective cover or a plastic protective cover is additionally arranged for use;

Specifically, the peripheral frame 22 extends from the shroud 20 to one side of the shroud 20, and the peripheral frame 22 surrounds the periphery of the fan 16. Here, the integral molding of the mask plate 20 and the peripheral frame 22 means that the mask plate 20 and the peripheral frame 22 are relatively fixed to each other and cannot be detached from each other during the specific manufacturing process.

In the preferred embodiment, since the shroud panel 20 and the peripheral frame 22 are integrally formed, it is not necessary to additionally provide a mounting structure between the shroud panel 20 and the peripheral frame 22 and to avoid mounting work between the shroud panel 20 and the peripheral panel, and when the mounting and dismounting are to be performed, it is sufficient to mount and dismount the entire fan assembly 14 as a whole. Therefore, the present invention provides a fan assembly 14 that is very convenient to install and disassemble and has a low manufacturing cost

Specifically, the cover plate 20 and the peripheral frame 22 are integrally injection molded from plastic. Of course, other materials, such as metal, may be used for the cover plate 20 and the peripheral frame 22. To reduce the weight of the fan assembly 14, the shroud 20 and the peripheral frame 22 may be made of a relatively light metal such as aluminum. The hood plate 20 and the peripheral frame 22 may be integrally cast, and in addition, the hood plate 20 and the peripheral frame 22 may be welded together.

The hollow protection structure on the cover plate 20 includes a plurality of through holes 24, and the plurality of through holes 24 are used for heat dissipation. The plurality of through holes 24 are generally sized so that a finger cannot pass through them. The plurality of through holes 24 may be completely different in size, or some of the through holes 24 may be the same in size, and some of the through holes 24 may be different in size. For ease of arrangement, the plurality of through-holes 24 are arranged in an arc centered on a central axis 26 of the fan 16.

The peripheral frame 22 is provided with a snap-fit arrangement by which the fan assembly 14 is mounted to the electronic control module 10. Specifically, the housing 12 has a receiving space therein, the fan assembly 14 is mounted in the receiving space, and the cover plate 20 is exposed to the outside. Further, the housing 12 is provided with a buckling portion 28, and the buckling structure can be coupled with or disengaged from the buckling portion 28.

That is, one end of the locking member 30 extends from the peripheral frame 22 to the outside of the peripheral frame 22, and the other end of the locking member 30 is a free end. The connecting portion 32 is connected to an end of the peripheral frame 22 remote from the hood panel 20, and the extending portion 34 extends from the connecting portion 32 at a small angle inclined outward in a direction gradually remote from the connecting portion 32. With this arrangement, the fan assembly 14 can be more reliably and stably fixed to the housing 12, and the force required for detaching the fan assembly 14 is not so large. Preferably, the inclination angle of the extension 34 is not less than 1 degree and not more than 5 degrees. In addition, the snap tab 40 is located approximately midway along the extension 34.

Specifically, in the present embodiment, the number of the clasps 30 is 4, and the structural forms of the 4 clasps 30 are the same. Of course, the structural form of the 4 clasps 30 can also be completely different or partially the same. The peripheral frame 22 is constituted by a first side plate 42, a second side plate 44, a third side plate 46 and a fourth side plate 48 which are connected in this order.

Further, the grommet 30 includes an operation portion 52 for an operator to operate, and the operation portion 52 and the connecting portion 32 are located at both ends and both sides of the extending portion 34. Specifically, the operating portion 52 is a bent portion bent outward from the extending portion 34 at a certain angle. This arrangement facilitates pressing of the catch 30 in a direction closer to the peripheral frame 22 when the fan assembly 14 is removed. Outward here is based on the peripheral frame 22, and the direction away from the peripheral frame 22 is outward.

The peripheral frame 22 is provided with a recess 54, and part of the snap structure is located in the recess 54. The arrangement is such that the fan assembly 14 is more compact and occupies less space. Specifically, the positions of the peripheral frame 22 where the 4 fasteners 30 are arranged are all provided with the concave parts 54.

The peripheral frame 22 is provided with a mounting portion 56, and the mounting portion 56 is used for mounting a terminal (not shown) electrically connected to the fan 16. Specifically, the mounting portion 56 defines a slide slot in which the terminal is mounted. The mounting portion 56 is directly fixedly provided outside the peripheral frame 22, and further, the mounting portion 56 is integrally formed on the peripheral frame 22. Specifically, in the present embodiment, the mounting portion 56 includes a first limiting wall 60 and a second limiting wall 62 protruding outward from the peripheral frame 22, the first limiting wall 60 and the second limiting wall 62 have a certain distance therebetween, and the first limiting wall 60 and the second limiting wall 62 are symmetrical in structural form. The first and second stopper walls 60 and 62 form a chute having an opening. In addition, the mounting portion 56 is provided on the second side plate 44. The electric control module 10 is provided with a socket. In this embodiment, the terminals are directly mounted to the mounting portions 56 of the peripheral frame 22 without providing additional components for mounting the terminals, and the terminals are plugged into the sockets (not shown) while the fan assembly 14 is mounted to the electronic control module 10.
