Embodiment

[0031] The core of the present invention is to provide a self-locking DC motor to alleviate the technical problem of poor self-locking performance of the DC motor in the prior art.

[0032] When the output shaft of a DC motor is connected to a heavy load, even after the motor stops rotating, the pressure of this load will cause the output shaft of the motor to rotate in reverse. Taking the lift table as an example, the output shaft of the existing ordinary DC motor directly drives the lifting of the table top. When the table top needs to be lowered, the motor reverses, and when the table top needs to be raised, the motor rotates forward. When in use, the user does not turn on the motor after adjusting the height of the desktop as required, and needs the desktop to be kept at this height all the time.

[0033] The problem found so far is that the desktop itself has a certain gravity, and objects are placed on the desktop, which will actually cause the output end of the motor un...

Abstract

The invention provides a latching direct current motor and relates to the technical field of motors. The latching direct current motor includes a direct current motor body of which the output end includes a locking mechanism. The locking mechanism enables the output end of the direct current motor to be latched through force closure, and therefore the technical problem is alleviated that in the prior art, existing direct current motors are poor in latching property. The invention further provides a lifting table including the latching direct current motor.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a self-locking DC motor. The present invention also relates to an elevating table with the above self-locking DC motor. Background technique [0002] DC motors need to realize self-locking function in many occasions. According to the different loads driven by the motor, for example, in many cases, the load must stop at a certain position, that is, the output shaft of the DC motor must pause and stop. [0003] At present, the self-locking of the motor mainly uses a mechanical method or an electromagnetic method. However, the current self-locking methods all have a problem: under heavy load, the working motor will have a tendency to rotate beyond the motor's own speed under the pressure of the load. This phenomenon causes either an increase in motor noise or an increase in the temperature of the motor. If the duration is long or the load is stressed enough, the motor will be dam...
