Description

Technical Field

[0001] This application relates to the field of mobile charging component technology, and more particularly to a conversion component and a mobile charging device. Background Technology

[0002] Existing mobile charging guns are typically fixed in location and cannot be moved. To use them, the vehicle must be parked near the mobile charging device, and the extended charging gun inserted into the vehicle's charging port, a cumbersome process. To address this, some manufacturers have produced mobile devices that combine the mobile device with the mobile charging gun, enabling the charging gun to be moved. However, these mobile devices generally consist of a roller assembly and a drive motor. The output gear of the drive motor meshes with the gears of the roller assembly, driving the roller assembly. Since the gears are always engaged, the movement is entirely controlled by the drive motor's signal. When the signal is weak or interfered with, a stop signal may not be received in time, leading to excessive movement, ineffective stopping, or even damage to the device.

[0003] Therefore, existing mobile devices have the problem of being unable to control the termination of movement in a timely and effective manner. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of this application is to provide a conversion component and a mobile charging device, which aims to solve the problem that existing mobile devices cannot control the termination of movement in a timely and effective manner.

[0005] The technical solution adopted by this application to solve the technical problem is as follows: a conversion component for a mobile charging device, the conversion component comprising:

[0006] A drive motor, the drive motor including an output end, on which a drive wheel is provided;

[0007] The converter includes a telescopic end, on which a first connector and a connecting bearing are provided; one end of the first connector is connected to the telescopic end, and the other end of the first connector is connected to the connecting bearing; the connecting bearing is sleeved on the outside of the output end and connected to the drive wheel.

[0008] The first wheel assembly has a transmission gear extending outward from it.

[0009] When the transmission gear meshes with the drive wheel, the drive motor drives the output end to rotate the drive wheel, thereby rotating the transmission gear and thus moving the first wheel set.

[0010] The converter drives the telescopic end to move, which in turn drives the connecting bearing to move through the first connector, thereby pushing the drive wheel to move and completing the engagement or disengagement of the drive wheel with the transmission gear.

[0011] Optionally, the conversion assembly further includes a slip ring, which includes a rotor, and a driven gear is provided at one end of the rotor; when the driving wheel meshes with the driven gear, the drive motor drives the output end to rotate the driving wheel, thereby driving the driven gear to rotate.

[0012] Optionally, the telescopic end is further provided with a fixing member, which is connected to the side of the first connecting member opposite to the telescopic end; the driven gear is provided with a plurality of engaging holes corresponding to the fixing member; when the fixing member is engaged with the engaging holes, the driven gear stops rotating.

[0013] Optionally, the first connector is provided with a second connector and is connected to the fixing member through the second connector, wherein the distance between the fixing member and the driving wheel is greater than or equal to the thickness of the driven gear.

[0014] Optionally, a locking shaft is sleeved on the output end, one end of the locking shaft is interference-fitted with the connecting bearing, and the other end of the locking shaft away from the connecting bearing is interference-fitted with the drive wheel, and the drive wheel is connected to the output end through the locking shaft;

[0015] The distance between the connecting bearing and the driving wheel is greater than the thickness of the transmission gear, and the diameter of the connecting bearing is greater than or equal to the diameter of the driving wheel.

[0016] On the other hand, this application also provides a mobile charging device, including a conversion component, which is the conversion component described above.

[0017] Optionally, the mobile charging device further includes a turntable and a drive shaft. The drive shaft is disposed between the turntable and the driven gear, and the turntable is connected to the rotor through the drive shaft. When the rotor rotates, it drives the drive shaft to move, thereby driving the turntable to rotate.

[0018] Optionally, the mobile charging device further includes a charging gun head and a charging gun wire, the charging gun head being connected to the charging gun wire, and the charging gun wire being wound around the turntable; when the rotor rotates, it drives the turntable to rotate, thereby realizing the collection and extension of the charging gun wire.

[0019] Optionally, the mobile charging device further includes a second wheel set and a base plate. The conversion components are all disposed on the base plate. The second wheel set is disposed on the base plate and is located on the side of the converter away from the first wheel set. When the first wheel set moves, the second wheel set moves accordingly, driving the base plate and the conversion components on the base plate to move together.

[0020] Optionally, the mobile charging device further includes a current collector and a controller that are electrically connected to each other. The current collector is electrically connected to the slip ring, and the controller is electrically connected to the drive motor and the telescopic end.

[0021] Compared with the prior art, this application provides a conversion component and a mobile charging device. The conversion component includes a drive motor, a converter, and a first wheel set. The converter can drive the telescopic end to move, and drive the connecting bearing to move through the first connector, thereby driving the drive wheel to move and completing the engagement or disengagement of the drive wheel with the transmission gear. When the transmission gear engages with the drive wheel, the drive motor drives the output end to rotate the drive wheel, thereby driving the transmission gear to rotate, and then driving the first wheel set to move, thus achieving the effect of movement. When movement is not required, the drive wheel is pushed to physically disengage from the transmission gear, thereby stopping the displacement in a timely and effective manner. The conversion component of this application realizes the start and end of the movement of the first wheel set by the engagement and disengagement of the drive wheel with the transmission gear, which has timeliness and stability and can reduce the instability caused by single signal control.

[0040] Reference Figure 1 The first embodiment of this application provides a conversion component for a mobile charging device. The conversion component includes: a drive motor 1, a converter 2, and a first wheel set 3. The drive motor 1 includes an output end, on which a drive wheel 11 is disposed. The converter 2 includes a telescopic end, on which a first connector 21 and a connecting bearing 22 are disposed. One end of the first connector 21 is connected to the telescopic end, and the other end of the first connector 21 is connected to the connecting bearing 22. The connecting bearing 22 is sleeved on the outside of the output end and connected to the drive wheel 11. The first wheel set 3 extends outward and is provided with a transmission gear 31.

[0041] When the transmission gear 31 meshes with the drive wheel 11, the drive motor 1 drives the output end to rotate the drive wheel 11, thereby rotating the transmission gear 31 and moving the first wheel set 3; the converter 2 drives the telescopic end to move, and drives the connecting bearing 22 to move through the first connecting member 21, thereby pushing the drive wheel 11 to move, completing the meshing or disengagement of the drive wheel 11 with the transmission gear 31.

[0042] The drive motor 1 drives the drive wheel 11 to rotate; the converter 2 drives the first connecting member 21 and the connecting bearing 22 at the telescopic end to move axially, that is, drives the first connecting member 21 to move the connecting bearing 22 axially in the drive motor 1, thereby connecting and pushing the drive wheel 11 to protrude or retract axially in the drive motor 1, thus realizing the engagement or disengagement of the drive wheel 11 with the transmission gear 31. Furthermore, the movement of the drive wheel 11 does not affect its rotation.

[0043] A conversion component in this embodiment includes a drive motor 1, a converter 2, and a first wheel set 3. The converter 2 can drive the telescopic end to move, and drive the connecting bearing 22 to move through the first connecting member 21, thereby pushing the drive wheel 11 to move, completing the engagement or disengagement of the drive wheel 11 with the transmission gear 31. When the transmission gear 31 is engaged with the drive wheel 11, the drive motor 1 drives the output end to rotate the drive wheel 11, thereby driving the transmission gear 31 to rotate, and then driving the first wheel set 3 to move, thereby achieving the effect of movement. When movement is not required, the drive wheel 11 is pushed to achieve physical disengagement from the transmission gear 31, thereby stopping the displacement in a timely and effective manner. The conversion component of this application realizes the start and end of the movement of the first wheel set 3 by engaging and disengaging the drive wheel 11 with the transmission gear 31, which has timeliness and stability and can reduce the instability caused by single signal control.

[0044] Reference Figure 2 and Figure 3 In some embodiments, the conversion assembly further includes a slip ring 4, which includes a rotor 41, one end of which is provided with a driven gear 411; when the driving wheel 11 meshes with the driven gear 411, the drive motor 1 drives the output end to rotate the driving wheel 11, thereby driving the driven gear 411 to rotate.

[0045] Both the transmission gear 31 and the driven gear 411 are located in the axial direction of the drive motor 1; the converter 2 drives the telescopic end to move, and drives 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 drive motor 1, completing the engagement or disengagement of the driving wheel 11 with the transmission gear 31, or completing the engagement or disengagement of the driving wheel 11 with the driven gear 411; thereby realizing the conversion between the movement of the first wheel set 3 and the collection and extension operation of the charging gun wire 6.

[0046] When the driving wheel 11 is pushed by the connected bearing 22 to mesh with the driven gear 411, it can realize the transition from the first wheel set 3 to the rotating state of the rotor 41. 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 with the driven gear 411, thereby retracting and extending the charging gun wire 6.

[0047] Specifically, the first wheel set 3 is provided with a pair of wheels, and each wheel is provided with a wheel gear below it. The wheel gear is connected to the transmission gear 31. When the transmission gear 31 rotates, it will drive the wheel gear to rotate, thereby driving the wheel to move. More specifically, the guide rail is located in the middle of the pair of wheels. When the wheel gear moves, the wheel can move along the guide rail, thereby making the first wheel set 3 move along the guide rail.

[0048] Furthermore, the telescopic end is also provided with a fixing member 24, which is connected to the side of the first connecting member 21 opposite to the telescopic end; the driven gear 411 is provided with a plurality of engaging holes 412 corresponding to the fixing member 24; when the fixing member 24 is engaged with the engaging holes 412, the driven gear 411 stops rotating.

[0049] When the driving wheel 11 is pushed by the connecting bearing 22 to separate from the driven gear 411 and then engage with the transmission gear 31, the fixing member 24 is inserted into the engagement hole 412, fixing the driven gear 411 and stopping its rotation, thereby stopping the collection and extension of the charging gun cable 6. That is, the fixing member 24 also has a certain limiting function, which can limit the movement position of the driving wheel 11 and ensure that the driven gear 411 stops moving when the driving wheel 11 is engaged with the transmission gear 31.

[0050] Furthermore, the first connecting member 21 is provided with a second connecting member 23, and is connected to the fixing member 24 through the second connecting member 23. 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.

[0051] The second connecting member 23 facilitates the connection between the first connecting member 21 and the fixing member 24; the distance between the fixing member 24 and the driving wheel 11 is set so that after the driving wheel 11 is completely separated from the driven gear 411, the driving gear 411 is fixed by the fixing member 24, thereby stopping the driven gear 411 from moving.

[0052] In some embodiments, a locking shaft 12 is fitted onto the output end. One end of the locking shaft 12 is interference-fitted with the connecting bearing 22, and the other end of the locking shaft 12, away from the connecting bearing 22, is interference-fitted with the drive wheel 11. The drive wheel 11 is connected to the output end via the locking shaft 12. Through this interference fit, the connecting bearing 22 drives the locking shaft 12, which in turn drives the drive wheel 11 to move axially upwards in the drive motor 1, without affecting the rotational movement of the drive motor 1, which in turn drives the connecting bearing 22, the locking shaft 12, and the drive wheel 11.

[0053] Furthermore, 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 the movement of the driving wheel 11 by driving the connecting bearing 22 through the converter 2, allowing the driving wheel 11 to completely separate from the transmission gear 31. Additionally, the connecting bearing 22 can be used to limit the extension of the driving wheel 11, preventing it from extending too far and separating from the output end of the drive motor 1, thus ensuring the stability of the connection between the driving wheel 11 and the drive motor 1.

[0054] Reference Figure 4 , Figure 5 and Figure 6 The second embodiment of this application provides a mobile charging device, including a conversion component, which is the conversion component as described in the first embodiment and any of its embodiments, and the displacement effect is achieved through the conversion component.

[0055] In some embodiments, the mobile charging device further includes a turntable 7 and a drive shaft 8, wherein the drive 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 drive shaft 8; when the rotor 41 rotates, it drives the drive shaft 8 to move, thereby driving the turntable 7 to rotate.

[0056] In some embodiments, a carbon brush is provided at one end of the drive shaft 8 near the rotor 41, and a conductive ring is provided at the connection between the turntable 7 and the drive shaft 8.

[0057] The carbon brush is used to connect to the rotor 41 to achieve current conduction or signal transmission, ensuring stable contact between the charging gun wire 6 and the rotor 41 via the drive shaft 8, thus achieving stability in current conduction and signal transmission. The conductive ring is used to electrically connect to the charging gun wire 6, further ensuring the stability of the contact between the charging gun wire 6 and the rotor 41 via the drive shaft 8; the conductive ring is made of metal or alloy, preferably copper.

[0058] In some embodiments, a first protrusion is provided at one end of the drive shaft 8 near the turntable 7, and a first groove corresponding to the first protrusion is provided on the turntable 7. The first protrusion and the first groove enable the turntable 7 and the drive shaft 8 to engage, thereby improving the stability of their connection. Specifically, a conductive ring is disposed inside the first groove, facilitating the stable contact and electrical connection of the charging gun wire 6 with the rotor 41 via the turntable 7 and the drive shaft 8 in sequence.

[0059] In some embodiments, a second protrusion is provided at one end of the drive shaft 8 near the rotor 41, and a second groove corresponding to the second protrusion is provided on the rotor 41. The second protrusion and the second groove enable the rotor 41 to engage with the drive shaft 8, thereby improving the stability of their connection.

[0060] Furthermore, the mobile charging device also 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 collection and extension of the charging gun wire 6.

[0061] The charging gun wire 6 can be wound around the turntable 7 and then connected to the rotor 41 through the drive 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 poor due to rotation. The rotor 41 can also rotate the turntable 7, thereby collecting or extending the charging gun wire 6 wound around the turntable 7.

[0062] Reference Figure 7 and Figure 8 The slip ring 4 also includes a stator housing 42 connected to the rotor 41. The stator housing 42 supports and protects the rotor 41 while it is rotating. The slip ring 4 ensures stable power and signal when the rotor 41 is rotating, thus providing stable power to 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, thereby supplying power to the charging gun wire 6 even during rotation, ensuring stable power and signal. The stator housing 42 has through holes corresponding to the rotor 41, which engage and fix the slip ring 42 to the rotor 41.

[0063] 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 drive shaft 8, sequentially 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 provided to facilitate 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.

[0064] In some embodiments, the stator housing 42 is provided with a plurality of contacts that are electrically connected to the rotor 41. The contact configuration facilitates the electrical connection of the external current collector 15 or the external power supply to the rotor 41 through the contacts, and then to the charging gun wire 6, thereby 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 supply through the rotor 41.

[0065] In some embodiments, the mobile charging device further includes a tubular support 81, which is sleeved on the outside of the drive shaft 8 and serves to support the drive shaft 8. The tubular support 81 not only supports the drive shaft 8 but also protects it from external damage.

[0066] A pressure sensor can be installed on the charging gun head 5 to identify whether the charging gun head 5 is in use. Specifically, when the charging gun head 5 is connected to the vehicle's charging port for use, the pressure sensor is pressed, and the charging gun head 5 is identified as being in use. When the charging gun head 5 is pulled out and placed down, the pressure sensor is not pressed, and the charging gun head 5 is identified as not being in use.

[0067] In some embodiments, the cross-section of the charging gun wire 6 is elliptical, square, or arched; or, the length of the cross-section of the charging gun wire 6 is less than the width of the cross-section. That is, the cross-section of the charging gun wire 6 is flat, which facilitates winding, elongation, and coiling in a compact space, making it easy to fix, reducing wear, and also increasing the heat dissipation area to prevent overheating.

[0068] Reference Figure 9 and Figure 10 In some embodiments, the mobile charging device further includes a second wheel set 10 and a base plate 9. The conversion components are all disposed on the base plate 9. The second wheel set 10 is disposed 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 moves accordingly, driving the base plate 9 and the conversion components on the base plate 9 to move together.

[0069] The second wheel set 10 is used in conjunction with the first wheel set 3. It can be fitted with different guide rails or simultaneously with the same guide rail. The second wheel set 10 and the first wheel set 3 provide two support points for connecting with the guide rail, thereby improving the stability of the connection between the mobile charging device and the guide rail.

[0070] When the first wheel set 3 moves on the guide rail via the rotation of the drive wheel 11, the second wheel set 10 moves in coordination with the first wheel set 3, thereby maintaining the steady state of the mobile charging device. Specifically, the conversion components are all mounted on the base plate 9. When the first wheel set 3 moves, it drives the base plate 9 and other structures of the conversion components on the base plate 9 to move in the same direction as the second wheel set 10.

[0071] The turntable 7 can be mounted on one side of the base plate 9 and move with the base plate 9. Specifically, the charging gun head 5 is wound around the turntable 7 via the charging gun wire 6. When the turntable 7 moves, the charging gun head 5 and the charging gun wire 6 also move with the turntable 7. This achieves the overall movement of the mobile charging device.

[0072] Specifically, the base plate 9 can be provided with a through hole for the connecting bearing 22 to pass through. The converter 2 is located below the base plate 9, while the drive motor 1 is located above the base plate 9. Specifically, the converter 2 is connected to the connecting bearing 22 through the first connector 21, and then connected to the drive motor 1 through the connecting bearing 22 passing through the base plate 9. This can separate the converter 2 and the drive motor 1, prevent the vibration generated during their operation from affecting each other, and also reduce the connection area between the two, reduce the heat transfer during their operation, and extend the service life of the drive motor 1 and the converter 2.

[0073] Meanwhile, the slip ring 4, drive shaft 8, first wheel set 3 and second wheel set 10 are all located above the base plate 9, and the connection between the second connecting piece 23 and the first connecting piece 21 is also located above the base plate 9, so that the fixing piece 24 can engage with the engagement hole 412 on the driven gear 411.

[0074] In some embodiments, the mobile charging 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.

[0075] The current collector 15 is connected to the slip ring 4, providing stable and reliable energy and signal transmission when the rotor 41 rotates. The specific 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, meaning the controller 14 can control the current collector 15, thereby controlling the energy and signal transmission of the rotor 41. The number of current collectors 15 can be set according to actual needs.

[0076] It can be connected to the controller 14 via an external power supply. The controller 14 supplies power to the collector 15, the drive motor 1, and the telescopic end. At the same time, the controller 14 adjusts the movement state of the collector 15, the drive motor 1, and the telescopic end, thereby automating the collection and extension of the charging gun wire 6, automating the displacement of the first wheel group 3, the second wheel group 10, and the mobile charging device as a whole, and improving the overall automation level of the mobile charging device.

[0077] Furthermore, the base plate 9 is provided with connecting protrusions or connecting engagement holes 412 corresponding to the conversion component, the tube support 81, the second wheel set 10, and the current collector 15, thereby fixing the positions of the conversion component, the tube support 81, the second wheel set 10, and the current collector 15 respectively; In addition, the conversion component, the tube support 81, the second wheel set 10, and the current collector 15 can be fixed to the base plate 9 with screws or bolts, thereby ensuring the stability of the connection of each component and preventing the position of each component from shifting, which would cause the mobile charging device to malfunction.

[0078] In some embodiments, the mobile charging device further includes a side plate 13 located on the side of the base plate 9 near the drive motor 1, and the controller 14 is disposed on the side plate 13 to facilitate connection between the controller 14 and the telescopic ends of the current collector 15, the drive motor 1, and the converter 2.

[0079] Meanwhile, a heat sink 16 is also provided on the side plate 13. There can be several heat sinks 16, specifically two, which are respectively set at both ends of the side plate 13. They can work together to ensure the ventilation of the mobile charging device, thereby preventing the mobile charging device from overheating. The heat sink 16 can also be connected to the controller 14, so that the power of the heat sink 16 can be adjusted according to the working status of the mobile charging device on the controller 14, ensuring that the mobile charging device can work normally.

[0080] In some embodiments, the mobile charging device further includes a fixed base 17, which is a hollow structure, and its front cross-section can be U-shaped. The turntable 7, the base plate 9, and the side plate 13 are all embedded in the fixed base 17. The turntable 7 is opposite to the left inner wall of the fixed base 17, and the side plate 13 is opposite to the right inner wall of the fixed base 17. The base plate 9 and the components on the base plate 9 are located between the turntable 7 and the side plate 13, so that the working status of the components on the base plate 9 can be observed. The bottom of the fixed base 17 is also provided with a through hole for the charging gun wire 6 to pass through.

[0081] The mounting base 17 is used to protect the mobile charging device and also allows for observation of the base plate 9 and the working status of the components on the base plate 9, thereby preventing emergencies.

[0082] In summary, this application provides a conversion component and a mobile charging device. The conversion component includes a drive motor, a converter, and a first wheel set. The converter can drive the telescopic end to move, and through the first connector, it drives the connecting bearing to move, thereby pushing the drive wheel to move and completing the engagement or disengagement of the drive wheel with the transmission gear. When the transmission gear engages with the drive wheel, the drive motor drives the output end to rotate the drive wheel, thereby driving the transmission gear to rotate, and then driving the first wheel set to move, thus achieving the effect of movement. When movement is not required, the drive wheel is pushed to physically disengage from the transmission gear, thereby stopping the displacement in a timely and effective manner. The conversion component of this application realizes the start and end of the movement of the first wheel set by the engagement and disengagement of the drive wheel with the transmission gear, which has timeliness and stability and can reduce the instability caused by single signal control.
