[0047] With reference to Figure 1 and Figure 2 In the first embodiment of the present application, a conversion assembly is provided for a movable charging device. The conversion assembly includes: a drive motor 1, a converter 2, a first wheel set 3, and a slip ring 4. The drive motor 1 includes an output end, and a driving wheel 11 is provided on the output end; the converter 2 includes a telescopic end, and a first connecting member 21 and a connecting bearing 22 are provided on the telescopic end; one end of the first connecting member 21 is connected to the telescopic end, and the other end of the first connecting member 21 is connected to the connecting bearing 22; the connecting bearing 22 is sleeved outside the output end and is connected to the driving wheel 11; the first wheel set 3 extends outwardly with a transmission gear 31; the slip ring 4 includes a rotor 41, and a driven gear 411 is provided at one end of the rotor 41; both the transmission gear 31 and the driven gear 411 are located in the axial direction of the drive motor 1.

[0048] The converter 2 drives the telescopic end to move, drives the connecting bearing 22 to move through the first connecting member 21, thereby pushing the driving wheel 11 to move in the axial direction of the drive motor 1, completing the engagement or separation between the driving wheel 11 and the transmission gear 31, or completing the engagement or separation between the driving wheel 11 and the driven gear 411; when the transmission gear 31 is engaged with the driving wheel 11, the drive motor 1 drives the output end to drive the driving wheel 11 to rotate, thereby driving the transmission gear 31 to rotate, and further driving the first wheel set 3 to move; when the driving wheel 11 is engaged with the driven gear 411, the drive motor 1 drives the output end to drive the driving wheel 11 to rotate, thereby driving the driven gear 411 to rotate.

[0049] Among them, the drive motor 1 is used to drive the driving wheel 11 to rotate; the converter 2 is used to drive the first connecting member 21 and the connecting bearing 22 at the telescopic end to perform axial displacement movement, that is, to drive the first connecting member 21 to drive the connecting bearing 22 to displace axially on the drive motor 1, thereby connecting and pushing the driving wheel 11 to protrude or retract axially on the drive motor 1, and further realizing the engagement or separation between the driving wheel 11 and the transmission gear 31. And while the driving wheel 11 is moving, it does not affect the rotation of the driving wheel 11.

[0050] When the driving wheel 11 is pushed by the connecting bearing 22 to move and engage with the driven gear 411, the conversion of the motion state from the first wheel set 3 to the rotation of the rotor 41 can be achieved; specifically, the rotor 41 can be electrically connected to an external power source, and the charging gun head 5 can be connected to the rotor 41 through the charging gun wire 6 to achieve charging. At the same time, the charging gun wire 6 can rotate following the driven gear 411 to retract and extend the charging gun wire 6.

[0051] Specifically, a pair of wheels are provided on the first wheel set 3, and wheel gears are provided below the wheels. The wheel gears are connected to the transmission gear 31. When the transmission gear 31 rotates, it will drive the wheel gears to rotate, thereby driving the wheels to move; more specifically, the guide rail is located in the middle of the pair of wheels. When the wheel gears move, the wheels can move along the guide rail, so that the first wheel set 3 moves along the guide rail.

[0052] The conversion assembly of this embodiment includes a driving machine 1, a converter 2, a first wheel set 3, and a slip ring 4. The converter 2 can drive the telescopic end to move, drive the connecting bearing 22 to move through the first connecting member 21, thereby pushing the driving wheel 11 to move along the axial direction of the driving machine 1, completing the engagement or separation of the driving wheel 11 and the transmission gear 31, or completing the engagement or separation of the driving wheel 11 and the driven gear 411; when the transmission gear 31 is engaged with the driving wheel 11, the driving machine 1 drives the output end to drive the driving wheel 11 to rotate, thereby driving the transmission gear 31 to rotate, and further driving the first wheel set 3 to move; when the driving wheel 11 is engaged with the driven gear 411, the driving machine 1 drives the output end to drive the driving wheel 11 to rotate, thereby driving the driven gear 411 to rotate; the slip ring 4 can be connected to the charging gun wire 6, so that through the rotation of the driven gear 411, the retraction of the charging gun wire 6 is driven.

[0053] The conversion assembly of this application realizes the start and end of the movement of the first wheel set 3 through the engagement and separation of the driving wheel 11 and the transmission gear 31, and realizes the retraction and extension of the charging gun wire 6 through the engagement and separation of the driving wheel 11 and the driven gear 411, separating the movement and retraction operations, reducing the structural complexity and control difficulty.

[0054] Combined with reference Figure 3 、 Figure 4 and Figure 5 In some embodiments, the slip ring 4 further includes a stator housing 42, and the stator housing 42 is connected to the rotor 41; when the driven gear 411 is engaged with the driving wheel 11, the driving machine 1 drives the output end to drive the driving wheel 11 to rotate, thereby driving the driven gear 411 to rotate relative to the stator housing 42.

[0055] The stator housing 42 can support and protect the rotor 41 while the rotor 41 is rotating; the slip ring 4 can ensure the stability of electric energy and signals when the rotor 41 is rotating, and then can conduct stable electric energy into the charging gun wire 6 to provide stable electric energy for the charging gun wire 6. Specifically, the slip ring 4 can be electrically connected to an external current collector 15 or an external power supply, so as to supply power to the charging gun wire 6 even in a rotating state and ensure the stability of electric energy and signals. A through hole corresponding to the rotor 41 is provided on the stator housing 42, and is fixedly connected to the rotor 41 by engaging through the through hole.

[0056] Furthermore, a fixing member 24 is provided at the telescopic end, and the fixing member 24 is connected to the side of the first connecting member 21 facing away from the telescopic end; a number of engaging holes 412 corresponding to the fixing member 24 are provided on the driven gear 411; when the fixing member 24 is engaged with the engaging holes 412, the driven gear 411 stops rotating.

[0057] When the driving wheel 11 is pushed by the connecting bearing 22 to move away from the driven gear 411 and then meshes with the transmission gear 31 at the same time, the fixing member 24 is inserted into the engaging holes 412, and the driven gear 411 is fixed and stops rotating, thereby stopping the retraction and elongation of the charging gun wire 6. That is, the fixing member 24 also has a certain limiting function, which can limit the moving position of the driving wheel 11 and ensure that the driven gear 411 stops moving when the driving wheel 11 meshes with the transmission gear 31.

[0058] Furthermore, a second connecting member 23 is provided on the first connecting member 21, and is connected to the fixing member 24 through the second connecting member 23, and the distance between the fixing member 24 and the driving wheel 11 is greater than or equal to the thickness of the driven gear 411.

[0059] The setting of the second connecting member 23 facilitates the connection between the first connecting member 21 and the fixing member 24; the setting of the distance between the fixing member 24 and the driving wheel 11 can enable the driven gear 411 to be fixed by the fixing member 24 after the driving wheel 11 is completely separated from the driven gear 411, so as to stop the movement of the driven gear 411.

[0060] In some embodiments, a clamping shaft 12 is sleeved on the output end, one end of the clamping shaft 12 is in interference fit with the connecting bearing 22, the end of the clamping shaft 12 facing away from the connecting bearing 22 is in interference fit with the driving wheel 11, and the driving wheel 11 is connected to the output end through the clamping shaft 12. Through the interference fit, the connecting bearing 22 drives the clamping shaft 12, and then drives the driving wheel 11 to axially displace on the driving machine 1, and at the same time does not affect the driving machine 1 to drive the connecting bearing 22, the clamping shaft 12 and the driving wheel 11 to rotate.

[0061] Further, the distance between the connecting bearing 22 and the driving wheel 11 is greater than the thickness of the transmission gear 31, and the diameter of the connecting bearing 22 is greater than or equal to the diameter of the driving wheel 11. This facilitates driving the connecting bearing 22 to drive the driving wheel 11 to move through the converter 2, enabling the driving wheel 11 to be completely separated from the transmission gear 31. Moreover, the connecting bearing 22 can be used for limiting, preventing the driving wheel 11 from extending too far, preventing the driving wheel 11 from separating from the output end of the driving machine 1, and ensuring the connection stability between the driving wheel 11 and the driving machine 1.

[0062] With reference to Figure 4 、 Figure 5 and Figure 6 , in the second embodiment of the present application, a movable charger device is provided, including a conversion assembly, where the conversion assembly is the conversion assembly as described in the first embodiment and any of its implementation manners, and the displacement effect is achieved through the conversion assembly.

[0063] In some implementation manners, the movable charger device further includes a turntable 7 and a transmission shaft 8. The transmission shaft 8 is disposed between the turntable 7 and the driven gear 411, and the turntable 7 is connected to the rotor 41 through the transmission shaft 8; when the rotor 41 rotates, it drives the transmission shaft 8 to move, and then drives the turntable 7 to rotate; a carbon brush is disposed at one end of the transmission shaft 8 close to the rotor 41, and a slip ring is disposed at the connection between the turntable 7 and the transmission shaft 8.

[0064] The carbon brush is used to connect with the rotor 41, thereby realizing current conduction or signal transmission, and can ensure the stable contact between the charging gun wire 6 and the rotor 41 through the transmission shaft 8, and realize the stability of current conduction and signal transmission. The slip ring is used to be electrically connected to the charging gun wire 6, further ensuring the stability of the contact between the charging gun wire 6 and the rotor 41 through the transmission shaft 8; the material of the slip ring is metal or alloy, preferably a copper slip ring.

[0065] In some implementation manners, a first protrusion is disposed at one end of the transmission shaft 8 close to the turntable 7, and a first groove corresponding to the first protrusion is disposed on the turntable 7. Through the setting of the first protrusion and the first groove, the turntable 7 and the transmission shaft 8 can be engaged, thereby improving the connection stability between the two. Specifically, the slip ring is disposed inside the first groove, facilitating the charging gun wire 6 to stably contact and be electrically connected to the rotor 41 through the turntable 7, the transmission shaft 8 in sequence.

[0066] In some implementation manners, a second protrusion is disposed at one end of the transmission shaft 8 close to the rotor 41, and a second groove corresponding to the second protrusion is disposed on the rotor 41. Through the setting of the second protrusion and the second groove, the rotor 41 and the transmission shaft 8 can be engaged, thereby improving the connection stability between the two.

[0067] Furthermore, the movable charger device further includes a charging gun head 5 and a charging gun wire 6. The charging gun head 5 is connected to the charging gun wire 6, and the charging gun wire 6 is wound around the turntable 7. When the rotor 41 rotates, it drives the turntable 7 to rotate, thereby realizing the retraction and elongation of the charging gun wire 6.

[0068] The charging gun wire 6 can be wound around the turntable 7 and then connected to the rotor 41 through the transmission shaft 8. When the rotor 41 is connected to an external power source, it can ensure that the charging gun wire 6 is in a stable working state. The external power source can supply power to the charging gun head 5 through the charging gun wire 6, and the working state of the charging gun head 5 will not be affected by rotation. It can also drive the turntable 7 to rotate through the rotation of the rotor 41, thereby retracting or elongating the charging gun wire 6 wound around the turntable 7.

[0069] Combined with reference Figure 6 and Figure 7 Furthermore, a second notch 72 corresponding to the first notch 71 is provided on the outer side of the turntable 7. One end of the charging gun wire 6 passes through the transmission shaft 8, sequentially passes through the first notch 71 and the second notch 72, and is wound around the turntable 7. The first notch 71 and the second notch 72 are correspondingly arranged, which is convenient for the charging gun wire 6 to pass through the center of the turntable 7 and then be wound around the outer side of the turntable 7.

[0070] In some embodiments, a plurality of contacts electrically connected to the rotor 41 are provided on the stator housing 42. The provision of the contacts facilitates the electrical connection between the external current collector 15 or the external power source and the rotor 41 through the contacts, and further facilitates the electrical connection with the charging gun wire 6, improving the stability and reliability of the electrical connection between the charging gun wire 6 and the external current collector 15 or the external power source through the rotor 41.

[0071] In some embodiments, the movable charger device further includes a tube support 81 sleeved outside the transmission shaft 8, and the tube support 81 is used to support the transmission shaft 8. The tube support 81 not only supports the transmission shaft 8 but also protects the transmission shaft 8, preventing the transmission shaft 8 from being damaged by the outside world.

[0072] A pressure sensor may be provided on the charging gun head 5 to identify whether the charging gun head 5 is in use through the pressure sensor. Specifically, when the charging gun head 5 is connected to the vehicle body charging port for use, the pressure sensor is pressed, and it is recognized that the charging gun head 5 is in use at this time; when the charging gun head 5 is placed after being pulled out, the pressure sensor is not pressed, and it is recognized that the charging gun head 5 is not in use at this time.

[0073] In some embodiments, the cross section of the charging gun wire 6 is oval, square or arched; or the length of the cross section of the charging gun wire 6 is smaller than the width of the cross section. That is, the cross section of the charging gun wire 6 is flat, which can be easily wound, stretched and collected in a compact space, easy to fix, reduce wear, and also increase the heat dissipation area to prevent overheating.

[0074] Combined with reference Figure 8 and Figure 9 In some embodiments, the movable charger device further includes a second wheel set 10 and a base plate 9, the conversion components are all arranged on the base plate 9, the second wheel set 10 is arranged on the base plate 9, and is located on the side of the converter 2 away from the first wheel set 3. When the first wheel set 3 moves, the second wheel set 10 follows the movement, driving the base plate 9 and the conversion components on the base plate 9 to move together.

[0075] The second wheel set 10 is used in conjunction with the first wheel set 3, and can be engaged with different guide rails respectively, or can be engaged with the same guide rail at the same time. The second wheel set 10 and the first wheel set 3 provide two support points for connecting to the guide rail, thereby improving the stability of the connection between the mobile charger device and the guide rail.

[0076] When the first wheel set 3 moves on the guide rail by rotating the driving wheel 11, the second wheel set 10 moves in coordination with the first wheel set 3, thereby maintaining the steady state of the mobile charger device. Specifically, the conversion components are all arranged on the bottom plate 9, and when the first wheel set 3 moves, the bottom plate 9 and other structures of the conversion components on the bottom plate 9 and the second wheel set 10 are driven to move in the same direction.

[0077] The turntable 7 can be arranged on one side of the bottom plate 9 and move along with the bottom plate 9. Specifically, the charging gun head 5 is wound around the turntable 7 through the charging gun wire 6. When the turntable 7 moves, the charging gun head 5 and the charging gun wire 6 also move along with the turntable 7. That is, the overall movement of the movable charger device is realized.

[0078] Specifically, a through hole for the connecting bearing 22 to pass through may be provided on the base plate 9, the converter 2 is located below the base plate 9, and the driving machine 1 is located above the base plate 9. Specifically, the converter 2 is connected to the connecting bearing 22 through a first connecting member 21, and then connected to the driving machine 1 through the connecting bearing 22 through the base plate 9; the converter 2 can be separated from the driving machine 1 to prevent the vibrations generated during the working process of the two from affecting each other, while also reducing the connection area between the two, reducing the heat transfer during the working process of the two, and extending the service life of the driving machine 1 and the converter 2.

[0079] Meanwhile, the slip ring 4, the transmission shaft 8, the first wheel set 3, and the second wheel set 10 are all located above the bottom plate 9, and the connection between the second connecting member 23 and the first connecting member 21 is also located above the bottom plate 9, facilitating the engagement of the fixing member 24 with the engagement hole 412 on the driven gear 411.

[0080] In some embodiments, the movable charger device further includes a current collector 15 and a controller 14 that are electrically connected to each other. The current collector 15 is electrically connected to the slip ring 4, and the controller 14 is electrically connected to the drive motor 1 and the telescopic end.

[0081] The connection between the current collector 15 and the slip ring 4 can provide stable and reliable energy and signal transmission when the rotor 41 rotates. Specifically, the current collector 15 can ensure a stable electrical connection with the rotor 41 through contacts. The current collector 15 is connected to the controller 14, that is, the controller 14 can control the current collector 15, and thus control the energy and signal transmission of the rotor 41. The number of current collectors 15 can be set according to actual needs.
