In the use process, in order to keep the torque of the motor, an adjusting mechanism needs to be configured, and the magnetic force generated by the electromagnetic device is usually used to achieve this. When adjustment is not needed, the electromagnetic device is powered on, and under the action of the magnetic force, the push rod retracts and compresses the corresponding spring. The amount of spring compression is only applicable to the electromagnetic device.

[0025] When the holding torque needs to be provided, the driving piece 4 drives the driving piece 5 to continuously linearly move, and then the elastic piece 7 pushes the push rod 6 to linearly move, so that the push rod 6 abuts against the side surface of the motor body 2, pushes against the side surface of the motor body 2, obtains the required holding torque, prevents the motor from being driven in reverse, and at the same time, the elastic piece 7 is pushed during the linear movement of the driving piece 5, the compression amount of the elastic piece 7 is adjusted, the size of the thrust force is adjusted, the required holding torque is obtained, different types of motors and layout modes are applicable, the service life is prolonged, the cost is reduced, and the applicability of the equipment is improved.

[0026] In the first embodiment, in order to stably place the elastic piece 7, the side surface of the driving piece 5 is opposite to the side surface of the push rod 6, the first baffle 51 is arranged on the side surface of the driving piece 5, the second baffle 61 is arranged on the side surface of the push rod 6, the leading end surface of the first baffle 51 is opposite to the trailing end surface of the second baffle 61, the elastic piece 7 is arranged between the first baffle 51 and the second baffle 61, and the two ends of the elastic piece 7 abut against the leading end surface of the first baffle 51 and the trailing end surface of the second baffle 61 respectively. During the working process, the driving piece 4 drives the driving piece 5 to move towards the leading end through the transmission piece, the first baffle 51 pushes the elastic piece 7 to compress, the elastic piece 7 pushes the second baffle 61 to linearly move towards the leading end, and then the linear movement of the push rod 6 is realized.

[0027] Specifically, the transmission member is a screw rod 9, the screw rod 9 is hinged to the support 3, the extension direction of the screw rod 9 is parallel to the extension direction of the push rod 6, the end of the screw rod 9 is connected to the driving member 4, and the driving member 4 drives the screw rod 9 to rotate. The driving member 4 drives the screw rod 9 to rotate, the screw rod 9 cooperates with the threaded hole of the driving member 5, and the driving member 5 moves linearly.

The first baffle 51 pushes the elastic member 7, the elastic member 7 pushes the second baffle 61 to move linearly towards the head end, thereby realizing the synchronous movement of the push rod 6 and the fourth baffle 62 towards the head end, and the end face of the first baffle 51 abuts against the head face of the fourth baffle 62, and the head face of the second baffle 61 abuts against the tail face of the third baffle 52, thereby avoiding excessive movement of the push rod 6. On the other hand, when the motor is reversely driven, the pinion is reversely rotated, drives the driving member 5 to move towards the tail end, at the same time, the first baffle 51 and the third baffle 52 move towards the tail end synchronously, since the end face of the first baffle 51 abuts against the head face of the fourth baffle 62, and the head face of the second baffle 61 abuts against the tail face of the third baffle 52, the second baffle 61 and the fourth baffle 62 are pushed to drive the push rod 6 to move towards the tail end.

A limiting step can be arranged at the opening of the sleeve in which the push rod 6 is arranged, and a limiting boss is arranged at a specific position in the middle of the push rod 6, when the compressed spring pushes the push rod 6 to move towards the head end, the head end surface of the limiting boss abuts against the tail end surface of the limiting step, so that the push rod 6 is prevented from being separated. On the other hand, when the motor rotates reversely, the driving member 5 is driven by the rack to move towards the tail end, the limiting boss is pushed by the limiting step, and then the push rod 6 is pushed to move towards the tail end.

[0038] In order to ensure the stable movement of the push rod 6, the support 3 includes a bottom plate and side plates arranged at both ends of the bottom plate, the rack can be directly machined on the side of the driving member 5, or separately machined and then installed on the side of the driving member 5.

Meanwhile, two ear plates are arranged on the bottom plate of the support 3. The ear plates are provided with connecting holes. The two ear plates are arranged staggered front and back, thereby improving the installation stability. Of course, other structures can also be adopted for the support, such as a frame structure. All of these are within the protection scope of the present application.

[0043] On the basis of the motor assembly provided in the above embodiments, the driving member 4 is specifically a motor. The motor can be connected to the connecting port through the terminal wire to provide power. The motor provides continuous and uninterrupted power output. Compared with the electromagnetic mode in the prior art, the continuous output mode of the motor can drive the driving member 5 to continuously linearly move, thereby adjusting the push force in real time. However, the electromagnetic mode can only provide a one-way displacement from the starting point to the end point, and cannot adjust the push force. Various types of continuous power output devices, such as hydraulic motors and pneumatic motors, can also be adopted. All of these are within the protection scope of the present application.

[0044] The motor assembly provided by the application is described in detail above. The principle and implementation mode of the application are described by using specific examples in this paper, and the above description of the examples is only used to help understand the method of the application and the core idea thereof. It should be pointed out that, for ordinary skilled persons in the technical field, some improvements and modifications can be made to the application without departing from the principle of the application, and these improvements and modifications also fall within the protection scope of the claims of the application.
