Description

TECHNICAL FIELD

[0001] The utility model relates to the field of bulb fan lamp especially, a kind of motor support and the fan lamp with the motor support of this. BACKGROUND

[0002] Bulb fan lamp is a kind of innovative home product integrating lighting and air circulation function, gradually becomes the practical choice of modern home with the multifunctional design and convenient installation mode. Appearance is similar with traditional bulb lamp, but small fan device is embedded inside, both provide efficient lighting, and promote indoor air flow through fan rotation, especially suitable for poor air circulation environment such as bedroom, study, living room or small office. User only needs to be screwed into ordinary threaded lamp holder, can enjoy the dual effect of light and breeze.

[0003] However, there are many inconveniences in the assembly process of existing bulb fan lamp, especially the installation link of fan driving motor. The motor driving fan usually adopts through-type motor shaft design, the motor shaft penetrates through the whole motor structure, and needs to be fixed in the central of bulb fan lamp shell, to ensure that fan normal operation. Therefore, special connecting components need to be set between motor shell and fan lamp shell, and the motor shaft and fan lamp shell are aligned during assembly to avoid axis deviation. If alignment is not accurate, mechanical interference may occur between motor shaft and fan blades, increasing friction and wear, shortening the service life of fan lamp.

[0004] This alignment and connection process not only increases assembly complexity, but also requires higher operating precision from workers, and slight carelessness may lead to assembly deviation, affecting operation stability. In batch production, this manual alignment method is difficult to ensure the precision consistency of each product, thereby affecting overall quality. In addition, the shell of bulb fan lamp is mostly made of plastic material, which has advantages in manufacturing cost and weight control, but the mechanical strength and long-term bearing capacity are weak. Usually, mounting groove is set on the plastic shell, and the motor is inserted into the mounting groove and fixed through interference fit, that is, the motor is tightly fitted by using the slight size difference between the outer diameter of the motor and the inner diameter of the mounting groove, and sometimes glue is smeared between the motor and the mounting groove to enhance stability.

[0005] However, this fixing method has hidden dangers in long-term use. The vibration generated by the continuous rotation of the fan is transmitted to the shell through the motor shaft, causing the connection part of the plastic shell and the motor to be stressed for a long time, which easily leads to fatigue deformation of the plastic material, and further loosens the fixation of the motor. When the interference fit is loosened due to plastic deformation, the motor may gradually come off the mounting groove, causing the fan to fail. In addition, the glue is easy to age and fail under the action of vibration and heat, further increasing the risk of motor falling off.

[0006] The above problems not only affect the service life and operation stability of the bulb fan lamp, but also increase the maintenance cost. Once the motor is loose or falls off, the user needs to disassemble the shell to re-fix the motor, which is time-consuming and laborious, and may cause secondary damage, reducing the user experience. Therefore, the existing bulb fan lamp needs to be improved in the installation and fixing mode of the motor to simplify the assembly process, improve the structural stability, reduce the long-term impact of vibration on the product, thereby improving the overall reliability and safety.
