[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and in no way limits the present invention and its application or use. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0033] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by orientation words such as "front, back, top, bottom, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom", etc. is usually based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description. Without contrary explanation, these orientation words do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation on the protection scope of the present invention; the orientation words "inside, outside" refer to the inside and outside relative to the contour of each component itself.

[0034] For the convenience of description, spatial relative terms such as "above...", "over...", "on the upper surface of...", "upper" etc. can be used here to describe the spatial positional relationship between a device or feature shown in the figure and other devices or features. It should be understood that the spatial relative terms are intended to include different orientations in use or operation in addition to the orientation described in the figure for the device. For example, if the device in the figure is inverted, the device described as "above other devices or structures" or "over other devices or structures" will then be positioned as "below other devices or structures" or "under other devices or structures". Thus, the exemplary term "above..." can include both the orientations of "above..." and "below...". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and corresponding interpretations are made for the spatial relative descriptions used here.

[0035] In addition, it should be noted that using words such as "first", "second", etc. to limit components is only for the convenience of distinguishing the corresponding components. Without additional statement, the above words have no special meaning. Therefore, it should not be construed as a limitation on the protection scope of the present invention.

[0036] Referring to Figures 4 - 10 As shown, according to an embodiment of the present invention, a wire outlet device is provided, including: a locking part 4, the locking part 4 is installed on the motor housing; a locking member 8, the locking member 8 is sleeved on the locking part 4, and the locking member 8 can move along the axial direction of the locking part 4 so that the locking member 8 adjusts the inner diameter size of the locking part 4. In this technical solution, by adjusting the inner diameter size of the locking part 4 through the locking member 8, the cumbersome steps of fixing the wire outlet sheath 2 with a cable tie 1 in the prior art are avoided. During use, only by moving the locking member 8, the locking part 4 can be fixed to the wire outlet sheath 2 to complete the assembly, eliminating the process of employees tying the cable tie, with simple operation and improved production efficiency.

[0037] Referring to Figures 1 to 3As shown, in the prior art, in the actual production process, due to the high labor intensity, fast rhythm, and cumbersome manual operation of the assembly line, there will be quality hazards such as missed bundling, over-bundling, and wrong bundling of the tie straps. Moreover, individual customers will specify the position size of the tie strap 1 or the orientation position of the tie strap head, increasing the quality hazard of wrong bundling of the tie strap 1. After the existing straight cylindrical wire outlet rubber nozzle 3 is assembled, the bundling process needs to be carried out manually to firmly bundle the sleeve, and the operation of the employee is relatively cumbersome. First, the tie strap needs to be taken, then the tie strap is pre-locked, and finally, the excess part is cut off by pulling firmly with pliers. This not only affects the production efficiency of the motor but also is not conducive to the lean development of the company.

[0038] In some embodiments, along the axial direction of the locking portion 4, the locking portion 4 has a first end and a second end. Along the direction from the first end towards the second end, the inner diameter of the locking portion 4 gradually increases. In this technical solution, along the direction from the first end towards the second end, the inner diameter of the locking portion 4 gradually increases, that is to say, the locking portion 4 is in a trumpet shape, which is convenient for the assembly of the wire outlet sheath 2 and the lead wire, and is also convenient for the adjustment of the inner diameter of the locking portion 4.

[0039] In some embodiments, a plurality of splitting grooves 10 are provided on the locking portion 4. The plurality of splitting grooves 10 are arranged at intervals along the circumferential direction of the locking portion 4. The splitting grooves 10 extend along the axial direction. Along the radial direction of the locking portion 4, the splitting grooves 10 penetrate through the locking portion 4. Along the axial direction of the locking portion 4, the splitting grooves 10 penetrate through the second end of the locking portion 4. In this technical solution, the locking portion 4 is split into a plurality of splitting strips 9 through the splitting grooves 10, so that the opening at the second end is larger, and the opening at the second end can also be adjusted, which is convenient for quickly passing out and straightening the power cord.

[0040] In some embodiments, along the circumferential direction of the locking portion 4, the splitting grooves 10 split the locking portion 4 into a plurality of splitting strips 9. Between two adjacent splitting strips 9, a protrusion 12 is provided on the side wall of one splitting strip 9, and a groove 13 is provided on the side wall of the other splitting strip 9. The protrusion 12 and the groove 13 are matched. In this technical solution, the locking protrusions 12 and the locking grooves 13 corresponding to each other are provided on the left and right sides of each splitting strip 9. Through the concave-convex structure, two adjacent splitting strips can be closely closed to achieve the sealing and waterproof effect.

[0041] It should be noted that the side wall of the splitting strip 9 refers to the side wall of the splitting strip 9 along the circumferential direction of the locking portion 4.

[0042] Furthermore, the protrusion 12 and the groove 13 can be provided in plurality. The plurality of protrusions 12 and the plurality of grooves 13 are arranged at intervals along the axial direction of the locking portion 4, and the plurality of protrusions 12 and the plurality of grooves 13 are arranged in one-to-one correspondence.

[0043] In some embodiments, a first thread is provided on the outer peripheral wall of the locking portion 4, and a second thread is provided on the inner peripheral wall of the locking member 8, and the first thread matches the second thread. In this technical solution, the locking function is realized by the cooperation of the inner thread of the locking portion 4 and the locking member 8, and the locking member 8 can also move on the locking portion 4, so as to realize the adjustment of the inner diameter of the locking portion 4.

[0044] Further, the locking member 8 is annular, and the locking member 8 is threadedly connected to the locking portion 4, so as to adjust the inner diameter of the locking portion 4.

[0045] In some embodiments, along the direction radially outward of the locking portion 4, a flanging 11 is provided at the second end of the locking portion 4. In this technical solution, to prevent the locking member 8 from being pulled forcefully past the second end due to improper manual operation, resulting in the detachment of the locking member 8, the flanging 11 is provided at the second end of the locking portion 4 to prevent the locking ring from falling off.

[0046] In the wire outlet device of the present invention, the locking portion 4 can also be referred to as a horn bowl portion. When not locked, the horn bowl portion is in a split strip shape that is centrosymmetric, and the larger opening facilitates employees to quickly pass the power cord through and straighten it. The number of the split strips 9 is indefinite, and it is greater than 1. There are sawteeth on the outer surface of the horn bowl portion, which can cooperate with the inner sawteeth of the locking member 8 to realize the locking function. In actual operation, the wire outlet sheath 2 is inserted into the barrel of the wire passing portion 6 of the wire outlet device, and then the locking member 8 is pulled towards the end of the horn bowl portion, so that the split strips 9 are tightened and gathered to form a closed barrel, completing the assembly, saving the employee the process of using binding straps, and the operation is simple. On the left and right sides of each split strip 9, there are corresponding locking protrusions 12 and locking grooves 13, and through the concave-convex structure, two adjacent split strips 9 can be closely closed to achieve the sealing and waterproof effect. To prevent the locking member 8 from being pulled too far due to improper employee operation, resulting in the detachment of the locking member 8, the end of the horn bowl portion is provided with a flanging 11 to prevent the locking ring from falling off.

[0047] In the wire outlet device of the present invention, the overall structural shape of the locking portion 4 is horn-shaped.

[0048] In some embodiments, the wire outlet device further includes a wire passing portion 6, the wire passing portion 6 has a third end and a fourth end, the fourth end is connected to the first end, and the outer diameter of the fourth end is not greater than the outer diameter of the first end. In this technical solution, through the arrangement of the wire passing portion 6, it is convenient to arrange the split groove 10 on the locking portion 4, improving the stability of the wire outlet device, and it is also convenient to install the locking portion 4 on the motor housing.

[0049] It should be noted that the wire passing portion 6 is in a cylindrical shape, and the inner diameter of the wire passing portion 6 is the same as the inner diameter of the first end to ensure that the lead wire smoothly passes through the wire passing portion 6 and enters the locking portion 4.

[0050] Further, when the wire-passing portion 6 is included, the split groove 10 can penetrate through the first end and the second end simultaneously. When the inner diameter of the locking portion 4 does not need to be adjusted, the locking member 8 can be sleeved on the wire-passing portion 6, and along the axial direction of the wire-passing portion 6, the locking member 8 can move on the wire-passing portion 6.

[0051] In some embodiments, a second stop portion 7 is provided on the wire-passing portion 6. The second stop portion 7 is arranged away from the first end, and the locking member 8 is located between the second stop portion 7 and the second end. In this technical solution, through the second stop portion 7, it is avoided that the locking member 8 falls off from the third end of the wire-passing portion 6 during installation.

[0052] The wire-passing portion 6 is a straight cylinder. The locking member 8 can be sleeved outside the cylinder, in contact with the cylinder body of the wire-passing portion 6. There are sawteeth on the inner side of the locking member 8, and the locking member 8 can be pulled. The inner diameter of the locking member 8 is smaller than that of the second stop portion 7, that is, during transportation and turnover, there is no quality risk of the locking member 8 falling off from the wire-passing portion 6. The material of the locking member 8 is relatively hard to increase the fastening and locking strength. And in order to facilitate the disassembly and repair of the motor, the locking member 8 can be directly cut open, replacing the function of the existing conventional binding wire. The operation of the employee is simple, the time consumption is short, and the efficiency is greatly improved.

[0053] In some embodiments, a first stop portion 14 is provided on the wire-passing portion 6. The first stop portion 14 is arranged close to the third end. An installation groove 5 is formed between the first stop portion 14 and the second stop portion 7. The installation groove 5 is used for installing the motor housing. In this technical solution, through the installation groove 5, during installation, the motor housing is clamped between the first stop portion 14 and the second stop portion 7, that is, the first stop portion 14 is located inside the motor housing, and the second stop portion 7 is located outside the motor housing, making the assembly between the wire outlet device and the motor housing more stable.

[0054] It should be noted that both the first stop portion 14 and the second stop portion 7 are provided on the outer peripheral wall of the wire-passing portion 6, and the outer diameter of the third end of the wire-passing portion 6 is larger than that of the fourth end. That is to say, along the direction from the fourth end to the third end, at least part of the outer diameter of the wire-passing portion 6 gradually increases. The purpose is to make the outer peripheral wall of the wire-passing portion 6 better fit with the motor housing and improve the waterproof performance of the motor.

[0055] Preferably, on the wire-passing portion 6, the outer diameter of the part between the second stop portion 7 and the third end remains unchanged, and from the middle of the wire-passing portion 6 to the second stop portion 7, the outer diameter of the wire-passing portion 6 gradually increases.

[0056] An installation groove 5 is provided on the wire passing part 6. The installation groove 5 is formed by the first stop 14 and the second stop 7. The outer shapes of the first stop and the second stop can be circular, square or other shapes, so as to adapt to the wire outlet hole of the motor end cover and meet the assembly requirements. The installation groove 5 is clamped at the wire outlet hole of the motor end cover by an interference fit method, so that the wire outlet device of the present invention is tightly installed on the motor end cover and is not easy to loosen.

[0057] Install and fix the wire outlet device of the present invention at the wire outlet hole of the motor end cover. The power cord passes through the wire outlet device, and then the power cord is straightened and all passed into the wire outlet sheath 2. At this time, the power cord is wrapped by the wire outlet sheath 2. Then, the wire outlet sheath 2 is pushed into the cylinder body of the wire passing part 6 of the wire outlet device. Finally, the locking part 8 is pulled towards the end of the locking part 4 of the wire outlet device, so that the split strip 9 is tightened and gathered to form a closed cylinder body, completing the assembly. The specifications of the wire outlet device of the present invention can be customized and selected according to the specifications of the wire outlet sheath 2 and the power cord required by the customer. Since the material of the wire outlet sheath 2 is usually soft and can be deformed, the inner diameter of the inner wall of the wire outlet device can be slightly smaller than the outer diameter of the outer peripheral wall of the wire outlet sheath 2 during selection, so as to achieve a tight fit, play a locking effect, and fix the wire outlet sheath 2 and the power cord.

[0058] The wire outlet device of the present invention solves the following technical problems:

[0059] 1. Eliminate the operation of employees using binding straps, simplify the production process, and improve production efficiency;

[0060] 2. Achieve staff reduction and efficiency increase, and reduce production costs;

[0061] 3. Improve the quality abnormalities such as missed binding, over-binding, wrong binding and loosening of the tie straps.

[0062] The wire outlet device of the present invention can not only simplify the production process, eliminate the operation of employees using binding straps, achieve staff reduction and efficiency increase, and reduce production costs, but also improve the quality abnormalities such as missed binding, over-binding, wrong binding and loosening of the tie straps. At the same time, it can also play the role of wire passing and waterproofing.

[0063] The present invention also provides a motor, including the above-mentioned wire outlet device.

[0064] For the motor of the present invention, after being assembled and locked using the wire outlet device in the motor general assembly production process, it can play the role of wire passing and waterproofing, while also simplifying the production process, improving production efficiency, and promoting the lean development of the company's products.

[0065] It is easy for those skilled in the art to understand that, on the premise of no conflict, the advantageous technical features of the above various methods can be freely combined and superimposed.
