The embodiments described below with reference to the drawings are exemplary only for the purpose of explaining the present invention, and should not be construed as limiting the present invention.

A fan 100 according to an embodiment of the present invention, including a fan housing 1 and a resistor mount 2, is described below with reference to fig. 1 to 4. Wherein, resistance mount pad 2 includes: a connecting portion 21 and a main body portion 22. As shown in fig. 1, the connection portion 21 is used to connect to the fan housing 1, so that after the resistor is mounted on the resistor mounting base 2, the resistor is connected to the fan housing 1 through the connection portion 21, thereby achieving the effect of stable connection between the resistor and the fan housing 1. The fan housing 1 may be other components in the vehicle, such as the electronic fan housing 1, a sensor, and the like, that is, the installation position of the resistor installation seat 2 of this embodiment is not unique, and when a fixed resistor needs to be installed, the connection between the resistor and the fan housing 1 may be achieved by arranging the resistor installation seat 2 at a specific position. Namely, the resistor mounting seat 2 can be changed along with the position change of the wind shield 1, and has the advantages of convenient installation and wide application.

And the main body part 22 is connected to the connecting part 21, and the main body part 22 defines a receiving space 221 for receiving the resistor, the receiving space 221 being configured as a groove shape. Specifically, as shown in fig. 2 and 4, the body 22 is formed in a cylindrical shape, a cutting groove penetrating through a wall surface is formed in a side wall of the body 22 in an axial direction to cut the body, and a mounting opening 2211 for mounting the resistor is formed in one side of the accommodating space 221, so that the difficulty of mounting the resistor can be reduced by the limit fit of the cutting groove and the mounting opening 2211 when the resistor is mounted.

Thus, when the resistor is mounted in the housing space 221, the resistor can be tightened by the circular side wall of the body portion 22. That is to say, the lateral wall structure of main part 22 is the arc form, and the resistance of parcel that can be fine for all receive the effect of main part 22 stirrup power in the resistance axial, guarantee that resistance and lateral wall laminating offset. Meanwhile, the body part 22 is hard, and the hardness of the body part 22 can reach HV 360-420, so that the resistor can be ensured to be assembled on the body part 22, the resistor is prevented from being separated due to the serious deformation of the body part 22, and the deformation of the body part 22 due to the overlarge external pressure can be avoided.

The end of the main body 22 in the accommodating space 221 is provided with a limiting structure, and the limiting structure is limited to abut against the end of the resistor. That is, the two ends of the main body 22 are provided with a limiting structure, when the resistor is installed in the accommodating space 221, the limiting structure will limit the axial movement of the resistor in the accommodating space 221, so as to ensure that the resistor will not be pulled out from the accommodating space 221. That is, the main body 22 is subject to external force or vibration during operation to cause axial movement of the resistor, and the limiting structure can ensure that the resistor can only move in the accommodating space 221 without falling out, thereby improving the stability of the resistor.

According to the utility model discloses fan 100, through setting up resistance mount pad 2, install resistance in the main part 22 of resistance mount pad 2, and main part 22 links to each other with connecting portion 21, be connected in order to realize the stable connection of resistance and fan housing 1 through connecting portion 21 and fan housing 1, wherein, be provided with the accommodation space 221 of long circle in main part 22 in order to be used for installation resistance, guarantee that the atress is even behind the resistance installation, and set up spacing portion in order to play spacing resistance's axial motion at accommodation space 221 tip, thereby guarantee that resistance can not deviate from main part 22.

In some embodiments, the body portion 22 is made of an elastically deformable material, and allows the opening width of the mounting opening 2211 to be adjustable. It should be noted that the main body portion 22 may be made of 65Mn spring steel, so that the main body portion 22 has elasticity. That is, the main body 22 is made of a material having elasticity to facilitate the mounting of the main body 22 and the resistor. When the resistor is mounted in the accommodating space 221, if the circumferential dimension of the body portion 22 is slightly smaller than the circumferential dimension of the resistor, the body portion 22 is made of an elastically deformable material, so that the body portion 22 can be expanded, the mounting of the resistor is satisfied, and the applicability of the resistor is improved. Simultaneously, the side wall of the main body part 22 is in contact with the resistor, the force application area of the stirrup is greatly increased, the periphery of the resistor is guaranteed to be under the action of the stirrup force, and the connecting effect of the resistor and the main body part 22 is improved. And, the elastic main body part 22 is also convenient for the disassembly of the resistor, thereby improving the disassembly efficiency.

The open width of the mounting port 2211 can be adjusted, the size range of the mountable resistor is further widened, resistors with different diameters can be conveniently and quickly mounted in the main body part 22 in a clamping mode, and the universality of products is improved.

In some embodiments, the open width of the mount 2211 is less than the outer diameter of the resistor with the body portion 22 in a naturally elongated state. That is, when the main body 22 is not mounted with the resistor, the size of the opening width of the mounting opening 2211 in the main body 22 is smaller than the size of the outer diameter of the resistor to be mounted. Therefore, when the resistor needs to be installed, the installation opening 21 is in clamping fit with the resistor, namely, pressure is applied to the resistor, so that the resistor is embedded into the installation opening 2211, and the installation effect is achieved. Meanwhile, since the opening width of the mounting opening 2211 is smaller than the outer diameter of the resistor, the mounting opening 2211 has the function of limiting the resistor, so that after the resistor is mounted in the main body 22, the resistor can be stably held in the accommodating space 221 by using the elastic force of the main body 22, thereby preventing the resistor from being separated from the mounting opening 2211 or falling off, and improving the assembly stability between the resistor and the mounting opening 2211.

In some embodiments, the limiting structure is configured as a limiting flange 222 protruding inwards at the end of the accommodating space 221, and a limiting surface is formed on one side of the limiting flange 222 facing into the accommodating space 221, and the limiting surface is attached to the end surface of the resistor. That is, as shown in fig. 2, the limiting flange 222 is configured as a rectangular convex structure toward the inside of the main body 22, and when the resistor is mounted in the accommodating space 221, the resistor will be abutted against the limiting flange 222 when moving axially in the accommodating space 221 to the end of the main body 22. Wherein, the one side that spacing turn-ups 222 and resistance offset is formed with the spacing face, can improve the area of contact of spacing turn-ups 222 and resistance through spacing face to increase the spacing power of spacing turn-ups 222 to resistance, and then promote the ability of spacing turn-ups 222 to the restriction resistance axial motion, the design of spacing face has still promoted the structural strength of spacing turn-ups 222 simultaneously, the cracked condition appears when avoiding spacing turn-ups 222 to receive the resistance impact force.

In some embodiments, there are two limiting flanges 222, and the two limiting flanges 222 are disposed at two opposite ends of the main body 22. That is, as shown in fig. 2, two ends of the main body 22 are respectively provided with one limiting flange 222, and it is ensured that the two limiting flanges 222 are axially and oppositely distributed. Therefore, after the resistor with the axial dimension smaller than that of the accommodating space 221 is installed in the accommodating space 221, the axial movement stroke of the resistor can be limited under the action of the two limiting flanges 222, so that the resistor is ensured not to fall off from the main body part 22. After the resistor with the same axial dimension as the accommodating space 221 is installed in the accommodating space 221, the resistor can also be abutted against two ends of the resistor through the two limiting flanges 222, so that the limiting and fixing effects on the resistor are achieved, and the resistor is prevented from falling off.

In some embodiments, the peripheral wall of the main body portion 22 is provided with a reinforcing rib 23, and the reinforcing rib 23 extends in the circumferential direction of the accommodating space 221. That is, as shown in fig. 3, two reinforcing ribs 23 are circumferentially provided on the outer peripheral wall of the main body portion 22, and the two reinforcing ribs 23 are provided spaced apart from each other in the axial direction.

Meanwhile, the two reinforcing ribs 23 with uniform intervals are arranged, so that the stress uniformity of the whole main body part 22 is facilitated, and the stability of the whole structure is improved.

In some embodiments, the reinforcing bead 23 is contiguous with the connecting portion 21. It will be appreciated that the connecting portion 21 is connected to the side wall of the main body portion 22 where the reinforcing bead 23 is located, and the reinforcing bead 23 is connected to the connecting portion 21. Therefore, the rigidity of the connecting part 21 can be improved, deformation is prevented when the connecting part 21 is connected with the fan cover 1, and the structural strength of the connecting part 21 is improved.

In some embodiments, the connecting portion 21 is a plurality of connecting portions 21, and the connecting portions 21 are spaced apart from each other in the length direction of the main body portion 22 and are located on the same side of the main body portion 22. That is, as shown in fig. 2, the plurality of connecting portions 21 are connected to the plurality of reinforcing beads 23 such that the plurality of connecting portions 21 are spaced apart from each other. And, one end of the connecting portion 21 is connected with the main body portion 22, and at the same time, is connected with the reinforcing rib 23 to improve the strength of the connecting portion 21, and at the same time, to ensure the stress uniformity of the connecting portion 21. The connecting portions 21 are disposed on the same side, so that the accommodating space 221 of the resistor mounting base 2 can be reduced, and the accommodating space 221 of other structures can be prevented from being occupied.

In some embodiments, the connection portion 21 is provided with a connection hole 211, and the connection hole 211 is used for penetrating a connection member connected to the wind shield 1. That is, as shown in fig. 2, wherein the connection part 21 may be configured as a rectangular sheet, a connection hole 211 is configured at the center of the connection part 21.
