A high-efficiency, shock-resistant, low-noise motor for elevator purification fans

Abstract

A high-efficiency, vibration-resistant, and low-noise elevator air purification fan motor belongs to the field of motor technology. By installing a flap on the upper casing of the motor body and supporting it with springs, the flap is lifted by the spring force when the elevator descends due to the downward potential energy, allowing normal air intake. When the elevator ascends, the upward potential energy collides with the air in the elevator shaft, causing the flap to flip down and block the air intake, preventing dust from the elevator shaft from entering the motor and thus extending its service life. Furthermore, by installing a shock-absorbing bracket, using a first and second shock-absorbing thin plate to support the motor body, vibration damping can be provided during elevator operation, thus preventing vibration from affecting motor operation.

Description

Technical Field

[0001] This utility model belongs to the field of motor technology, specifically relating to a high-efficiency, shock-resistant, low-noise motor for elevator purification fans. Background Technology

[0002] An electric motor, also known as a motor, is an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction. In circuit diagrams, it is represented by the letter M (formerly D). Its main function is to generate driving torque, serving as a power source for electrical appliances or various machines; the electric motor is a type of power equipment.

[0003] In elevator applications, the elevator car is a relatively enclosed space, requiring the installation of a purification fan to replace the air inside. Typically, the fan is installed outside the car, filtering the air in the elevator shaft and sending it into the car. However, the motor is exposed in the elevator shaft, and when the elevator is running, it stirs up dust from the shaft, which then enters the motor through the ventilation holes, affecting its heat dissipation. Currently, most motors are simply fixed in place, usually with a bracket at the bottom of the motor that is in direct contact with the car, resulting in poor vibration damping. Summary of the Invention

[0004] The present invention aims to solve the technical problems existing in the prior art and provide a high-efficiency, shock-resistant, low-noise motor for elevator purification fans.

[0005] The above-mentioned technical problems of this utility model are mainly solved by the following technical solution: a high-efficiency, shock-resistant, low-noise elevator purification fan motor, including a motor body and a shock-absorbing bracket. The motor body is mounted on the shock-absorbing bracket and is installed upside down on the shock-absorbing bracket. The motor body includes an upper shell and a lower shell. The top of the upper shell has two symmetrically arranged recessed grooves. Multiple air inlets are provided in the recessed grooves. An intermediate frame plate is formed on the upper shell between the two recessed grooves. A groove is provided on the upper surface of the intermediate frame plate. Filter cotton cores are provided in both recessed grooves. A set of supports is provided on the upper shell on both sides of the intermediate frame plate. A flap is connected between the two supports. The flap completely covers the filter cotton cores. A pin is provided at the front and rear ends of the adjacent side of the two flaps. The flap is connected to the support through the pin. A spring is provided in the groove at the top of the upper shell. The middle position of the spring is embedded in the groove for fixation. The middle part of the spring is straight, and the left and right ends are curved upwards and abut against the lower surface of the flap.

[0006] Preferably, the shock-absorbing bracket includes a middle connecting part, two first shock-absorbing thin plates and two second shock-absorbing thin plates. The two first shock-absorbing thin plates are disposed on the left and right sides of the middle connecting part, and the middle position of the two second shock-absorbing thin plates is connected to the outer end of the first shock-absorbing thin plate.

[0007] Preferably, the second damping plate is positioned lower than the height of the intermediate connecting plate, the front and rear ends of the second damping plate are lower than the middle part, and a connecting hole is provided at the end position.

[0008] The beneficial effects of this utility model are as follows: By setting a flap on the upper shell of the motor body and supporting it with a spring, when the elevator descends, the flap is bounced up by the spring force due to the downward potential energy, allowing normal air intake. When the elevator ascends, the upward potential energy collides with the air in the elevator shaft and causes the flap to flip down, blocking the air intake and preventing dust in the elevator shaft from entering the motor, thereby improving the service life of the motor. By setting a shock-absorbing bracket and using the first and second shock-absorbing thin plates to support the motor body, the motor body can be supported and damped during elevator operation, thereby avoiding vibration from affecting the motor operation.

[0013] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0014] Example: A high-efficiency, shock-resistant, low-noise motor for elevator purification fans, such as... Figures 1-3As shown, the device includes a motor body 1 and a shock-absorbing bracket 2. The motor body 1 is mounted on the shock-absorbing bracket 2, and is installed upside down on the shock-absorbing bracket 2. The motor body 1 includes an upper shell 3 and a lower shell 4. The top of the upper shell 3 has two symmetrically arranged recessed grooves 5, and multiple air inlets 6 are provided in the recessed grooves 5. An intermediate frame plate 7 is formed on the upper shell 3 between the two recessed grooves 5. The upper surface of the intermediate frame plate 7 has a groove 8. Filter cotton cores 9 are provided in both recessed grooves 5. The intermediate frame plate 7 is arranged on the left and right sides. Each of the two upper housings 3 is provided with a set of supports 10. A flap 11 is connected between the two supports 10. The flap 11 completely covers the filter cotton core 9. A pin 12 is provided at the front and rear ends of the two flaps 11 on the adjacent side. The flap 11 is connected to the support 10 through the pin 12. A spring 13 is provided in the groove 8 at the top of the upper housing 3. The middle position of the spring 13 is embedded in the groove 8 for fixation. The middle part of the spring 13 is straight, and the left and right ends are raised upward to abut against the lower surface of the flap 11.

[0015] The shock-absorbing bracket 2 includes a middle connecting part 14, two first shock-absorbing thin plates 15 and two second shock-absorbing thin plates 16. The two first shock-absorbing thin plates 15 are located on the left and right sides of the middle connecting part 14, and the middle position of the two second shock-absorbing thin plates 16 is connected to the outer end of the first shock-absorbing thin plates 15.

[0016] The second shock-absorbing plate 16 is positioned lower than the height of the intermediate connecting plate, and the front and rear ends of the second shock-absorbing plate 16 are lower than the middle part, with connecting holes 17 provided at the ends.

[0017] The principle of this utility model is as follows: In use, the motor body 1 is supported by the shock-absorbing bracket 2. The motor body 1 is installed upside down, with the drive unit facing down and connected to the impeller in the fan. The elastic force of the spring 13 and the weight of the flap 11 are calculated so that when the elevator is stopped, the elastic force of the spring 13 can lift the flap 11, exposing the filter cotton core 9, which facilitates heat dissipation of the motor. When the elevator rises, the air in the elevator shaft will hit the two flaps 11, thereby pressing the flaps 11 onto the sink 5, preventing dust in the air from entering the interior of the motor body 1 through the air inlet 6 and accumulating over time, which would affect the operation of the motor.

[0018] The shock-absorbing bracket 2 can support the motor body 1 on the car, thereby achieving the effect of shock absorption.

[0019] Finally, it should be noted that the above embodiments are merely representative examples of this utility model. Obviously, this utility model is not limited to the above embodiments and can have many variations. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model should be considered to fall within the protection scope of this utility model.
