Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. The components of embodiments of the present invention, as generally described and illustrated in the figures herein, may be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the present invention, presented in the accompanying drawings, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. Based on the embodiment of the present invention, all other embodiments obtained by the person skilled in the art without creative work belong to the protection scope of the present invention.

As is known, inside an electric machine there is a machine stator and a machine rotor, and the electric machine drives the electric machine via a machine line. And in the motor rotation process, if the motor line and the motor rotor contact and rub, the motor line can be damaged. Therefore, in order to protect the motor wires, an outlet baffle is usually disposed between the motor housing and the motor rotor or the motor stator to isolate the motor wires from the motor rotor.

At present, an outlet baffle of a motor wire is generally fastened on a motor shell by a screw, so that a channel for accommodating the motor wire to pass through is formed between the outlet baffle and the motor shell, as shown in fig. 7 and 8, the outlet baffle 20 is fastened on the shell 10 by a screw 30. However, in the above-mentioned manner, in the process of assembling the motor, the assembling efficiency of the motor may be reduced by fastening the screw, and the problem of inconvenience in the manufacturing process, increase in the manufacturing cost, and the like may be caused by forming the screw hole in the radial direction.

In order to solve the above problems, the applicant found in the research that the motor wire can be protected as long as the motor wire can be separated from the motor rotor or the motor stator. Therefore, the applicant designs a drawing type clapboard which is matched with a drawing groove on a motor shell and does not need to be fastened by using screws. Thereby avoiding using the screw to fasten the baffle of being qualified for the next round of competitions.

The scheme is further illustrated by the following examples:

as shown in fig. 1 to 5, the motor 1000 includes a rotor 200, a stator 210 and a housing 100, an axially extending drawing slot 110 is provided on an inner wall of the housing 100, the motor 1000 further includes a drawing plate 300 in sliding fit with the drawing slot 110, a radial wire outlet channel 102 is formed between an axial inner side 111 of the drawing slot 110 and the axial inner side 111 of the drawing plate 300, an axial wire outlet channel 101 is formed between a radial inner side 112 of the drawing slot 110 and a radial outer side 302 of the drawing plate 300, and the radial wire outlet channel 102 is communicated with the axial wire outlet channel 101.

The housing 100 includes a first housing 120 and a second housing 130, and an accommodating space is formed between the first housing 120 and the second housing 130, and the rotor 200 and the stator 210 are installed in the accommodating space between the first housing 120 and the second housing 130. It should be noted that the second housing 130 is provided with an outlet hole 131, and the outlet hole 131 is communicated with the axial outlet channel 101.

Further, the drawing groove 110 is provided on the first housing 120, and specifically, in the illustrated embodiment, the drawing groove 110 is a groove similar to an "n" type in a radial direction.

Meanwhile, the drawing plate 300 is directly placed in the drawing groove 110. When the first housing 120 and the second housing 130 are fastened together, the drawing plate 300 is blocked by the second housing 130 in the axial direction, and at this time, the drawing plate 300 cannot move axially.

Meanwhile, a gap is left between the axial outer side surface 301 of the drawing plate 300 and the axial inner side surface 111 of the drawing groove 110 to form an axial wire outlet channel 101 for placing the motor wire 400. It should be noted that a gap is left between the axial inner side surface 112 of the drawing slot 110 and the axial outer side surface 302 of the drawing plate 300, so as to form a radial wire outlet channel 102 for placing the motor wire 400.

Therefore, the motor wire 400 on the rotor 200 is arranged along the radial outlet channel 102 and the axial outlet channel 101, and finally extends out of the housing from the outlet hole 131.

In the above manner, the following technical effects can be achieved: through the cooperation of pull board 300 and pull groove 110, need not to use the screw, alright keep apart with rotor 200 and stator 210 in order to make motor line 400 to protection motor line 400 contact friction, and then protection motor line. Meanwhile, the fixing is not carried out by using screws, so that the installation is more convenient.

In the above embodiment, as shown in fig. 3 and 5, the outer side surface of the drawing plate 300 is fitted to the inner side surface of the drawing groove 110. In the above manner, the following technical effects can be achieved: the outer side surface of the drawing plate 300 is embedded with the inner side surface of the drawing groove 110, so that the drawing plate 300 is prevented from moving radially, and the drawing plate 300 is fastened in the drawing groove 110.

In the above embodiment, as shown in fig. 3 and 4, the drawing plate 300 has an arc-shaped sliding outer side surface 310, and the drawing groove 110 has an arc-shaped sliding inner side surface 113 matching with the arc-shaped sliding outer side surface 310.

In another variant, the outer side of the pull-out plate 300 and the inner side of the pull-out groove 110 may alternatively be provided with other shaped surfaces, such as a "concave-convex" shaped surface, as shown in fig. 6

Furthermore, the present application also relates to a robot joint comprising the aforementioned motor 1000.
