[0002] In the related art, a rotor power supply system supplies power to a rotor in a magnetic drive transmission line, including a rotor, a stator, and a sliding contact wire. The rotor is slidably connected to the stator and continuously contacts the sliding contact wire. The sliding contact wire can supply power to the contacted components.

Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.

[0033] Please refer to Figures 1 - 5 As shown, the present utility model provides a mover power supply system, including a stator and a mover. The stator includes a plurality of stator units 100, and each stator unit 100 includes a sliding contact wire 110; the plurality of stator units 100 are arranged in a first direction (i.e., the front-back direction shown in Figure 1 ), and adjacent stator units 100 are detachably connected. The mover includes a mover body 210 and a power taking part 230. The mover body 210 is movably connected to the stator in the first direction and can move from one stator unit 100 to an adjacent stator unit 100 in the first direction; the power taking part 230 is connected to the mover body 210 and can be electrically connected to the sliding contact wire 110 in different stator units 100 following the movement of the mover body 210.

[0034] The mover can move along the first direction on the stator including a plurality of stator units 100 and is electrically connected to the sliding contact wire 110 of the stator unit 100 through the power taking part 230, so as to receive the electric energy provided by the sliding contact wire 110; when the mover body 210 moves from one stator unit 100 to another stator unit 100 in the first direction, the power taking part 230 also moves from one stator unit 100 to another stator unit 100 along the first direction following the mover body 210 and is electrically connected to the sliding contact wire 110 of the other stator unit 100, then the mover can receive the electric energy provided by the sliding contact wire 110 of different stator units 100 when moving to different stator units 100.

[0035] The following introduces the specific scheme for the mover body 210 to move between different stator units 100.

[0036] Please refer to Figure 1 and Figure 2 , in some embodiments, the mover body 210 includes a first moving part 220, and the stator unit 100 further includes a guide rail 150. The guide rail 150 extends in the first direction; the first moving part 220 is slidably connected to the guide rail 150. Since the guide rail 150 extends in the first direction, the mover body 210 can slide relative to the stator unit 100 along the guide rail 150 through the first moving part 220 in the first direction, and the guide rail 150 can limit the movement of the first moving part 220 perpendicular to the first direction.

[0037] In one embodiment, the projections of the guide rails 150 of adjacent stator units 100 along the first direction completely overlap, and the interval between the two guide rails 150 in the first direction is less than the length of the first moving part 220 in the first direction. Then, during the process of the first moving part 220 sliding from one guide rail 150 to another guide rail 150, a part of the first moving part 220 can first be slidably connected to the other guide rail 150, and the first moving part 220 can be supported by the limiting effect of the other guide rail 150 so that the remaining part of the first moving part 220 can be more smoothly slidably connected to the other guide rail 150.

[0038] Please refer to Figure 1 , in some embodiments, the mover body 210 includes a second moving part 240, and the upper surface of the stator unit 100 has a guiding plane 160 parallel to the first direction; the second moving part 240 can move along the first direction on the guiding plane 160.

[0039] The guiding planes 160 of adjacent stator units 100 are coplanar, and the interval between the two guiding planes 160 in the first direction is less than the length of the second moving part 240 in the first direction. Then, during the process of the second moving part 240 moving from one guiding plane 160 to another guiding plane 160, a part of the second moving part 240 can first move to the other guiding plane 160, and the second moving part 240 can be supported by the supporting effect of the other guiding plane 160 so that the remaining part of the second moving part 240 can be more smoothly moved to the other guiding plane 160.

[0040] For the mover power supply system of the present utility model, since the stator unit 100 is detachably connected to another adjacent stator unit 100, the staff can additionally connect the same stator unit 100 to the original multiple stator units 100 arranged in the first direction and connected in pairs to form a stator with a larger specification and increase the moving range of the mover along the first direction, thereby increasing the overall specification of the mover power supply system; the staff can also release the detachable connection between the two stator units 100 in the stator, split it into a stator with a smaller specification, and reduce the moving range of the mover along the first direction, thereby reducing the overall specification of the mover power supply system.

[0041] The above adjustment method for the specification of the power supply system can directly adjust the total number of the sliding contact lines 110, thereby making corresponding adjustments to the specification of the sliding contact lines 110, saving the disassembly and assembly process of the sliding contact lines 110, and making the adjustment of the specification of the mover power supply system itself more convenient.

[0042] Those skilled in the art can use fasteners such as bolts and pins to connect adjacent stator units 100 to achieve the detachable connection of adjacent stator units 100.

[0043] Please refer to Figure 3 , Figure 5As shown, further, in some embodiments, the stator unit 100 includes a unit body 120 and a docking member 130. The docking member 130 is connected to the unit body 120, and a part of the docking member 130 protrudes from the unit body 120 in the first direction; the docking member 130 is detachably connected to the unit body 120 of an adjacent stator unit 100; in other embodiments, the docking member 130 is detachably connected to the docking member 130 of an adjacent stator unit 100. When assembling the stator, the staff can use the part of the docking member 130 that protrudes from the unit body 120 in the first direction to connect adjacent stator units 100; the part of the docking member 130 that protrudes from the unit body 120 in the first direction can also provide a direction reference for the staff during the stator assembly to confirm the installation position.

[0044] Please refer to Figure 1 、 Figure 3 As shown, further, in some embodiments, the unit body 120 has a docking groove 140; in other embodiments, the docking member 130 has a docking groove 140; the docking groove 140 extends in the first direction, and a part of the docking member 130 is received in the docking groove 140 of an adjacent stator unit 100. When a part of the docking member 130 is received in the docking groove 140 of an adjacent stator unit 100, the inner wall of the docking groove 140 can limit the docking member 130 and restrict the movement of the docking member 130 relative to the adjacent stator unit 100 in a direction perpendicular to the first direction, further enhancing the stability of the connected stator units 100. On the other hand, during the installation process, the limiting effect of the inner wall of the docking groove 140 on the docking member 130 can also facilitate the staff to position the installation position of the docking member 130 in the adjacent stator unit 100.

[0045] Please refer to Figure 1 、 Figure 3 As shown, as a preferred solution, in some embodiments, the unit body 120 has a docking groove 140. The docking groove 140 penetrates the unit body 120 in the first direction and communicates with the docking groove 140 of an adjacent stator unit 100; a part of the docking member 130 is received in the docking groove 140, connected to the inner wall of the docking groove 140 and extends in the first direction. A part of the docking member 130 protrudes from the unit body 120 in the first direction. The distance between one end of the docking member 130 in the length direction and the same end of the docking member 130 of an adjacent stator unit 100 in the length direction is the same as the length of the docking groove 140 extending in the first direction. The inner wall of the docking groove 140 can limit the movement of the docking member 130 relative to the unit body 120 in a direction perpendicular to the first direction, enabling the staff to position the docking member 130 through the limiting effect of the inner wall of the docking groove 140 during the assembly of the stator unit 100, facilitating the assembly of the stator unit 100.

[0046] On the other hand, since the distance between one end of the docking member 130 in the first direction and the same end of the adjacent docking member 130 is designed to be the same as the length of the docking groove 140 extending in the first direction, when a part of the docking member 130 protrudes relative to the unit body 120 in the first direction, there will be a dislocation between the docking member 130 and the docking groove 140 in the first direction, enabling the docking groove 140 to accommodate the docking member 130 of the adjacent stator unit 100 and playing a limiting role on the docking member 130 of the adjacent stator unit 100. Moreover, since the docking groove 140 penetrates the unit body 120, during the assembly process, the staff can also align according to the docking groove 140 of a certain stator unit 100 and the docking groove 140 of the adjacent stator unit 100.

[0047] Furthermore, in some embodiments, the sliding contact wire 110 has a contact surface 111 for contacting the power taking part 230, and the contact surfaces 111 of each sliding contact wire 110 are coplanar. When the power taking part 230 moves to different stator units 100, the coplanar sliding contact wires 110 can prevent the power taking part 230 from moving in a direction perpendicular to the first direction in order to contact the sliding contact wire 110, thereby reducing the movement of the power taking part 230 relative to the mover body 210 and enhancing the stability of the mover movement.

[0048] As previously mentioned, there is a scheme in which the stator unit 100 is connected to the adjacent stator unit 100 through the docking member 130. Further, in some embodiments, the sliding contact wire 110 is connected to the docking member 130 and the contact surfaces 111 of each sliding contact wire 110 are coplanar. When assembling multiple stator units 100, the staff can adjust the degree of connection between the docking members 130 connecting adjacent stator units 100 according to whether the contact surfaces 111 are coplanar. Exemplarily, when the docking member 130 is connected to the adjacent stator unit 100 by bolts, the staff can determine the tightening force of the bolts with reference to whether the contact surfaces 111 are coplanar.

[0049] Regarding the specific power taking scheme of the power taking part 230 of the mover power supply system of the present utility model, in some embodiments, the power taking part 230 includes a collecting carbon brush, which is made of a mixture of graphite and metal powder and can slide on the surface of the sliding contact wire 110 when following the movement of the mover body 210, and the sliding contact wire 110 can transmit electric energy to the collecting carbon brush.

[0050] Please refer to Figures 1 - 4 As shown, as a preferred scheme, in some embodiments, the power taking part 230 includes a conductive roller 231, and the conductive roller 231 contacts the sliding contact wire 110; when the mover moves relative to the stator in the first direction, the conductive roller 231 rolls along the sliding contact wire 110. Compared with the collecting carbon brush, since the conductive roller 231 can receive the electric energy of the sliding contact wire 110 in a rolling state, the wear is less and the service life is longer.

[0051] Please refer toFigure 4 As shown, further, in some embodiments, the power taking part 230 includes a plurality of conductive rollers 231, and the plurality of conductive rollers 231 are arranged in the first direction; when the mover moves relative to the stator in the first direction, each conductive roller 231 rolls along the sliding contact wire 110. The plurality of rollers of the power taking part 230 roll simultaneously following the movement of the mover body 210 and take power from the sliding contact wire 110 at the same time; since the plurality of conductive rollers 231 are arranged in the first direction, when the power taking part 230 moves in the first direction, the sliding contact wire 110 and the components supporting the sliding contact wire 110 can support the power taking part 230 at a plurality of contact positions with the conductive rollers 231, making the movement of the power taking part 230 more stable. On the other hand, in the process of the power taking part 230 moving from one stator unit 100 to another stator unit 100, a part of the conductive rollers 231 can first contact another sliding contact wire 110, and support the power taking part 230 through the supporting action of the other sliding contact wire 110 and the components supporting the sliding contact wire 110, so that the remaining conductive rollers 231 can slide more smoothly onto another sliding contact wire 110.

[0052] Further, in some embodiments, the conductive roller 231 is a conductive bearing, and the outer ring of the conductive bearing can rotate relative to the inner ring and is electrically connected to the inner ring. Then, when the outer ring of the conductive bearing rolls relative to the sliding contact wire 110, the inner ring can remain stationary and receive the electric energy of the sliding contact wire 110 through the outer ring; when the components fixed to the mover are electrically connected to the inner ring through wires, since the inner ring and the components are relatively stationary, the wires will not move relative to the inner ring and the components as the power taking part 230 moves, and the electric energy of the sliding contact wire 110 can stably pass through the outer ring, inner ring and wires of the conductive bearing and be introduced into the components.

[0053] Please refer to Figure 4 As shown, further, in some embodiments, the power taking part 230 further includes an elastic member 232. One end of the elastic member 232 is connected to a conductive roller 231, and the other end is connected to the mover body 210; the conductive roller 231 receives an elastic force in the direction close to the sliding contact wire 110 from the elastic member 232. Through the elastic force in the direction close to the sliding contact wire 110 applied by the elastic member 232 to the conductive roller 231, the conductive roller 231 can recover contact with the sliding contact wire 110 when it is accidentally separated from the sliding contact wire 110 by an external force, ensuring that the conductive roller 231 can stably receive the electric energy of the sliding contact wire 110 during long-term operation.

[0054] Please refer to Figure 3 、 Figure 5 and Figure 6As shown, further, in some embodiments, the stator unit 100 further includes a docking member 130. The docking member 130 extends along a first direction. The sliding contact wire 110 is connected to the docking member 130 and is located on the upper surface of the docking member 130, and extends along the first direction to both ends of the docking member 130. Along a second direction, the projection portions of the adjacent docking members 130 supporting the upper surface of the sliding contact wire 110 overlap. The second direction is perpendicular to the first direction and parallel to the upper surface of the docking member 130. Along the second direction, the projection of the upper surfaces of the two docking members 130 is a line. When there is an overlapping area in the projection of the upper surfaces of the two docking members 130, when an object is placed on the upper surface of the docking member 130 corresponding to the overlapping area, the object can be supported by the two docking members 130 at the same time. The sliding contact wire 110 can support the power taking part 230 whose size in the second direction is smaller than that of the sliding contact wire 110. Then, when the projection portions of the two docking members 130 for supporting the upper surface of the sliding contact wire 110 overlap, during the process that the power taking part 230 moves from the surface of one sliding contact wire 110 to the surface of the other sliding contact wire 110, a part of the power taking part 230 will first separate from the surface part of the original sliding contact wire 110 and is no longer supported by the docking member 130, and first contacts the surface of the other sliding contact wire 110 and is supported by the other docking member 130, while the other part of the power taking part 230 is still supported by the original docking member 130, so that the docking member 130 supporting the power taking part 230 gradually changes from the original docking member 130 to the other docking member 130. The above solution can reduce the contact area between the power taking part 230 and the second docking member 130b during the process of transferring from one docking member 130 to the other docking member 130, make the movement of the power taking part 230 more smooth during the movement between different stator units 100, and reduce the impact received when moving to the other docking member 130.

[0055] Exemplarily, please refer to Figure 5 and Figure 6 , wherein Figure 6 is Figure 5Schematic diagram of the mating of the docking member 130 with another docking member 130 after the two stator units 100 are connected, and it shows the situation where the first sliding contact wire 110a is connected to the upper surface of the first docking member 130a and the second sliding contact wire 110b is connected to the upper surface of the second docking member 130b; in some embodiments, both ends of the docking member 130 are intercepted by a plane that is inclined relative to the first direction and perpendicular to the vertical direction, and the position of the upper left endpoint of the first sliding contact wire 110a along the first direction is more forward than the position of the lower right endpoint of the second sliding contact wire 110b along the first direction. Then, in the second direction, the projection parts of the upper surfaces of the two docking members 130 that support the sliding contact wire 110 overlap. During the process of the power-taking part 230 located on the first sliding contact wire 110a moving to the second sliding contact wire 110b, for the power-taking part 230 that was originally completely supported by the first docking member 130a, the right side part of the power-taking part 230 used to contact the sliding contact wire 110 will first disengage from the first sliding contact wire 110a and contact the second sliding contact wire 110b, and will first be supported by the second docking member 130b. As the power-taking part 230 moves along the first direction, the part of the power-taking part 230 supported by the second docking member 130b will gradually increase, and the part of the power-taking part 230 supported by the first docking member 130a will gradually decrease until the power-taking part 230 is completely supported by the second docking member 130b.

[0056] Without departing from the inventive concept of the present invention, the shapes of the mating end faces of the first docking member 130a and the second docking member 130b are not limited to the above embodiments. The end face of the first docking member 130a in the first direction and the end face of the second docking member 130b in the first direction can also be mating sawtooth shapes, etc.

[0057] The above has described the embodiments of the present invention in detail with reference to the drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art to which the present invention pertains, various changes can be made without departing from the gist of the present invention. In addition, without conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.
