Description

Technical Field

[0001] The utility model belongs to the technical field of air conditioners, and in particular relates to a fixing bracket for an air conditioner fan and an air conditioner fan component. Background Art

[0002] In existing air-conditioning products, the fan is a core operating component, and it is inevitable that vibration will occur during its operation due to dynamic balance problems. This vibration not only affects the operating efficiency of the air conditioner, but may also damage the fan bearings and increase maintenance costs. In order to effectively suppress the vibration of the fan during operation and reduce the risk of damage to the fan bearings, a fan bracket is usually used to fix the fan on a high-rigidity base. Traditional fan bracket designs mostly use sheet metal parts to assemble into a fan cage or use profiles to assemble into a grid structure to root and fix the motor on the plane of the air guide ring. However, this structure places high demands on the rigidity design of the fan frame, and the deformation control of the rooting position is also extremely strict.

[0003] In addition, there are also long beams made of sheet metal materials to directly fix the motor. Although this form of fixation is relatively easy to implement, it occupies a large ventilation area and also creates a large obstruction to the airflow, thereby affecting the overall ventilation efficiency of the air conditioner. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a fixing bracket and an air-conditioning fan assembly for an air-conditioning fan, which can directly fix the fan and effectively reduce the problem of fan vibration, while opening up the airflow field channel and effectively reducing the resistance of the airflow field.

The fixed bracket in this technical solution is suitable for wind turbines with a larger weight, and the first mounting rod, the third mounting rod, and the second mounting rod and the fourth mounting rod form closed ends with the ends of the first fixed extension arm, the second fixed extension arm, the third fixed extension arm and the fourth fixed extension arm, so that the fixed bracket as a whole is more stable.

[0015] Furthermore, the mounting rod assembly further includes a first fixed extension arm, a second fixed extension arm, a third fixed extension arm and a fourth fixed extension arm in the shape of a letter "I", wherein the first fixed extension arm, the second fixed extension arm, the third fixed extension arm and the fourth fixed extension arm are respectively fixedly connected to the two ends of the first mounting rod; the second fixed extension arm and the third fixed extension arm are respectively fixedly connected to the two ends of the third mounting rod. The fixed bracket is also suitable for fans with a larger weight, and more mounting parts make the connection between the fixed bracket and the frame more stable.

[0046] The following is a further detailed introduction to each of the above components.

[0047] Example 1

[0048] The structure of the fixing bracket 100 in this embodiment is as follows Figure 1 As shown, the fixing bracket 100 for an air conditioner fan includes a fan mounting plate 110 , a mounting rod assembly 120 and a plurality of mounting portions 130 .
