Description

Technical Field

[0001] The utility model belongs to the technical field of motors, and in particular relates to an escalator motor with high heat dissipation performance. Background Art

[0002] A motor is an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction. The output shaft rotates through electromagnetic induction. There are many types of motors, including DC motors, asynchronous motors, and synchronous motors. The outside of the motor is usually equipped with multiple sets of heat dissipation fins. The heat dissipation fins are mostly made of metal, which helps to conduct the temperature inside the motor to the outside.

[0003] In the prior art, the heat dissipation fins of the motor are usually fixedly installed on the outside of the motor, and the number of the heat dissipation fins on the outside of the motor cannot be adjusted. When the heat dissipation demand of the motor is large, the heat dissipation performance of the motor cannot be improved, which is relatively inconvenient. Utility Model Content

[0004] In order to solve the above technical problems, the utility model further proposes an escalator motor with high heat dissipation performance.

[0005] The specific technical solution of the utility model is as follows: An escalator motor with high heat dissipation performance comprises: a shell, a plurality of first heat sinks are arranged in a circumferential array on the shell, a first rotating ring and a second rotating ring are rotatably connected on the shell, a plurality of second heat sinks are arranged in a circumferential array on the first rotating ring, a plurality of third heat sinks are arranged in a circumferential array on the second rotating ring, the number of the first heat sink, the second heat sink and the third heat sink are equal, a single first heat sink, the second heat sink and the third heat sink form a group and fit together for heat conduction, and a plurality of the second heat sinks and the third heat sink are all fit together for heat conduction with the shell.

[0006] Furthermore, it also includes: an angle locking mechanism, and the first rotating ring and the second rotating ring are both equipped with an angle locking mechanism.

[0007] Furthermore, the angle locking mechanism includes: a positioning through hole, the first rotating ring is provided with a positioning through hole, a positioning pin is installed in the positioning through hole, and the housing is provided with an initial positioning hole and an end positioning hole for cooperating with the positioning pin.

[0008] Furthermore, a pull ring is provided on the positioning pin.

[0009] Furthermore, two limiting rings are installed on the housing to prevent the first rotating ring and the second rotating ring from falling off.

[0010] Furthermore, a fixed support seat is installed on the limiting ring.

[0011] Beneficial effects:

[0012] The present application is connected to a first rotating ring and a second rotating ring by rotating on the shell, a plurality of second heat sinks are arranged in a circumferential array on the first rotating ring, and a plurality of third heat sinks are arranged in a circumferential array on the second rotating ring. When the motor is installed in a position where the heat dissipation demand is greater, the first rotating ring and the second rotating ring can be rotated, so that the second heat sink and the third heat sink are separated from the first heat sink, the number of heat sink fins is increased, and the heat dissipation area in contact with the air is expanded, thereby improving the overall heat dissipation performance of the motor.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] In the description of the present invention, it should be understood that the terms "upper", "middle", "outer", "inner" and the like indicating directions or positional relationships are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention.

[0022] Example 1: An escalator motor with high heat dissipation performance, comprising: a housing 1, a plurality of first heat sinks 2 are arranged in a circumferential array on the housing 1, a first rotating ring 3 and a second rotating ring 4 are rotatably connected to the housing 1, a plurality of second heat sinks 5 are arranged in a circumferential array on the first rotating ring 3, a plurality of third heat sinks 6 are arranged in a circumferential array on the second rotating ring 4, the number of the first heat sink 2, the second heat sink 5 and the third heat sink 6 are equal, a single first heat sink 2, the second heat sink 5 and the third heat sink 6 form a group and fit together to conduct heat, a plurality of the second heat sink 5 and The third heat sink 6 is in close contact with the shell 1 for heat conduction. In this application, a first rotating ring 3 and a second rotating ring 4 are connected to the shell 1 through rotation. A plurality of second heat sinks 5 are arranged in a circumferential array on the first rotating ring 3, and a plurality of third heat sinks 6 are arranged in a circumferential array on the second rotating ring 4. When the motor is installed in a position where the heat dissipation demand is greater, the first rotating ring 3 and the second rotating ring 4 can be rotated to separate the second heat sink 5 and the third heat sink 6 from the first heat sink 2, thereby increasing the number of heat dissipation fins and expanding the heat dissipation area in contact with the air, thereby improving the overall heat dissipation performance of the motor.

[0023] Example 2: Based on Example 1, it also includes: an angle locking mechanism 7, and the first rotating ring 3 and the second rotating ring 4 are both equipped with an angle locking mechanism 7. This application installs the angle locking mechanism 7 on the first rotating ring 3 and the second rotating ring 4, so that after the motor unfolds the heat dissipation fins, the rotation angle of the first rotating ring 3 and the second rotating ring 4 can be fixed by the angle locking mechanism 7, thereby ensuring that the second heat sink 5 and the third heat sink 6 do not contact the first heat sink 2, thereby improving the heat dissipation effect.

[0024] Example 3: Based on Example 2, the angle locking mechanism 7 includes: a positioning through hole 71, a positioning through hole 71 is provided on the first rotating ring 3, a positioning pin 72 is installed in the positioning through hole 71, and an initial positioning hole 73 and an end positioning hole 74 for cooperating with the positioning pin 72 are provided on the shell 1. In this application, a positioning through hole 71 is provided on the first rotating ring 3, a positioning pin 72 is installed in the positioning through hole 71, and an initial positioning hole 73 and an end positioning hole 74 for cooperating with the positioning pin 72 are provided on the shell 1, so that the first rotating ring 3 can be locked by the positioning pin 72 when it is rotated to the angle at which the fins are unfolded, thereby ensuring that the second heat sink 5 does not contact the first heat sink 2, thereby improving the heat dissipation effect.

[0025] Example 4: Based on Example 3, a pull-out ring 75 is provided on the positioning pin 72. The present application provides a pull-out ring 75 on the positioning pin 72 to facilitate the operator to insert and remove the positioning pin 72, thereby improving the operational convenience.

[0026] Example 5: Based on Example 1, two limiting rings 8 are installed on the shell 1 to prevent the first rotating ring 3 and the second rotating ring 4 from falling off. This application prevents the first rotating ring 3 and the second rotating ring 4 from falling off from the shell 1 during the operation of the motor by installing two limiting rings 8 on the shell 1, thereby improving the stability of use.

[0027] Example 6: Based on Example 5, a fixed support seat 9 is installed on the limit ring 8. This application avoids interference of the fixed support seat 9 on the installation when disassembling and assembling the first rotating ring 3 and the second rotating ring 4, thereby improving the disassembly and assembly efficiency.

[0028] Working process:

[0029] When the heat dissipation performance of the motor needs to be improved, first pull out the positioning pin 72 from the initial positioning hole 73 and the positioning through hole 71, then rotate the first rotating ring 3 and the second rotating ring 4, thereby driving the second heat sink 5 and the third heat sink 6 to move away from the first heat sink 2, and stop when the positioning through hole 71 coincides with the end positioning hole 74, and finally insert the positioning pin 72 into the positioning through hole 71 and the end positioning hole 74.
