[0031] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings. Example 1
[0032] Please refer to Figure 1-3, a motor with a flexible cable, comprising a cable interface 100 located at the rear end of the top surface of a housing 200, the cable interface 100 faces the output shaft 300 and is parallel to the housing 200, and also comprises: a connector 400, a guide tube 500 and a cable assembly 600, the connector 400 is arranged at the rear end of the top surface of the housing 200, and the cable interface 100 is located at the front side of the connector 400; two guide tubes 500 are both arranged at the cable interface 100, and the guide tubes 500 are parallel to the housing 200; a first end of the cable assembly 600 is located inside the housing 200 and is electrically connected to a motor control end, a second end of the cable assembly 600 extends from the connector 400 and passes through the guide tube 500, and the cable assembly 600 comprises a signal line 610 and a power line 620, and the transverse cross-sectional area of the signal line 610 and the power line 620 is 0.5 square millimeters.
[0033] Through the above-mentioned structural design, the cable assembly 600 is led out from the connector 400 and the guide tube 500, which is conducive to planning the range of activities of the cable assembly 600 and preventing the cable assembly 600 from bending and breaking. At the same time, the cross-section of the signal line 610 and the power line 620 is set at 0.4~0.6 square millimeters to ensure the connection strength at the connecting terminal, which will not be broken due to the torque transmitted by the twisting of the wire harness. At the same time, the wire diameter of the power line 620 bundle is reduced to increase the signal line 610 to reserve the internal connection space of the motor, which is conducive to preventing the cable assembly 600 from being strained during activities and increasing the life of the Sierra door motor.
[0034] Specifically, the connector 400 includes a guide assembly 410, which includes a pulley 411 and several sliding bars 412. The several sliding bars 412 are respectively arranged on the left and right sides of the signal line 610 and the left and right sides of the power line 620. The pulley 411 is sleeved on the sliding bar 412, and the cable assembly 600 and the pulley 411 are in contact with each other.
[0035] Through the above structural design, a pulley 411 is mounted on the slide bar 412, which is used to guide the cable assembly 600 inside the connector 400. The slide bar 412 equipped with the pulley 411 is arranged on the left and right sides of the signal line 610 and the power line 620. When the signal line 610 and the power line 620 are repeatedly pulled, the pulleys 411 on the left and right sides assist in guiding, which helps to prevent the cable assembly 600 from getting stuck when the motor moves.
[0036] Specifically, the connector 400 also includes a reset assembly 420, which includes a guide rod 421, a fixed pulley 422, a movable pulley 423 and an elastic strip 424. The four guide rods 421 are arranged at the upper and lower ends inside the connector 400, the movable pulley 423 and the fixed pulley 422 are respectively mounted on different guide rods 421, the elastic strip 424 is mounted on the movable pulley 423 and the fixed pulley 422, and the cable assembly 600 passes through the middle of the elastic strips 424 at the left and right ends and contacts with the elastic strips 424.
[0037] Through the above structural design, the reset assembly 420 is used to reset the cable assembly 600. When the cable assembly 600 is pulled, the movable pulley 423 is driven, so that the elastic strip 424 and the passive pulley 423 are driven and tightened in a certain direction. When the cable assembly 600 is reset, the elastic strip 424 recovers elastically, causing the movable pulley 423 to rotate in the opposite direction, so that the cable assembly 600 returns to its original position. Example 2
[0038] The motor with a flexible cable provided in Example 1 is further optimized, specifically, as follows Figure 3 As shown, the elastic strip 424 is made of natural rubber or synthetic rubber.
[0039] By the above-mentioned structural design, in the present embodiment, the material of making elastic strip 424 is natural rubber, and natural rubber is made from the sap extracted from rubber tree through processing. This material has good flexibility and toughness, and is one of the main raw materials for making rubber band. The manufacturing process of natural rubber is relatively simple, and the production cost is relatively low. Meanwhile, the environmental protection and degradability of natural rubber are also generally recognized. Example 3
[0040] The motor with a flexible cable provided in embodiment 1 or 2 is further optimized, such as Figure 3 As shown, the movable pulley 423 is disposed on the guide rod 421 close to the cable assembly 600 , and the fixed pulley 422 is disposed on the guide rod 421 away from the cable assembly 600 .
[0041] Through the above structural design, the reset assembly 420 is used to reset the cable assembly 600. When the cable assembly 600 is pulled, the movable pulley 423 is driven, so that the elastic strip 424 and the passive pulley 423 are driven and tightened in a certain direction. When the cable assembly 600 is reset, the elastic strip 424 recovers elastically, causing the movable pulley 423 to rotate in the opposite direction, so that the cable assembly 600 returns to its original position.
[0042] Specifically, the connector 400 further includes a tension sensor 700 for determining the tension of the cable assembly 600 .
[0043] Specifically, the tension sensor 700 is disposed inside the connector 400 , and the tension sensor 700 is electrically connected to the control system.
[0044] Through the above structural design, the tension sensor 700 generally adopts the physical strain principle. When subjected to external force, it will cause the strain of the strain gauge inside the sensor to change, and these changes will be converted into electrical signal output through the sensor chip.
[0045] Specifically, the guide tube 500 is made of silicone.
[0046] Through the above structural design, the guide tube 500 is made of silicone, which can greatly reduce the probability of the guide tube 500 being damaged and increase the life of the guide tube 500.
[0047] The beneficial effects of the motor with a flexible cable provided by the utility model are as follows:
[0048] The cable assembly 600 is led out from the connector 400 and the guide tube 500, which is conducive to planning the range of movement of the cable assembly 600 and preventing the cable from being frequently bent and broken. At the same time, the cross-section of the signal line 610 and the power line 620 is set at 0.4~0.6 square millimeters to ensure the connection strength at the connecting terminal and prevent it from breaking due to the torque transmitted by the twisting of the wire harness. At the same time, the wire diameter of the power line 620 bundle is reduced to increase the signal line 610 to reserve internal connection space for the motor, which is conducive to preventing the cable assembly 600 from being strained during activity and increasing the life of the Sierra door motor.
