[0039] See also Figure 1-Figure 6 The embodiment of the present application provides a power supply device 10. The power supply device 10 provided in the embodiment of the present application can provide power to the vehicle 30 without stopping the vehicle 30, thereby greatly improving work efficiency.

[0040] See also Figure 1 and Figure 2 The embodiment of the present application provides a power supply device 10, which is arranged outside a railway. The power supply device 10 includes a base 100 and a conductive part 200 movably arranged on the base 100. The conductive part 200 has a standby position and a power supply position on the base 100. In response to a vehicle 30 passing by the power supply device 10, the conductive part 200 switches to the power supply position to connect with the power receiving device 20 on the vehicle 30.

[0041] The conductive part 200 is a conductive medium that can be used for conducting electricity. The conductive part 200 is in a standby position when not being charged, so as not to interfere with the operation of the railway under normal circumstances. When the conductive part 200 needs to be charged, it is switched to the power supply position, that is, it invades the boundary of the railway, so that it can be connected to the power receiving device 20. And because the conductive part 200 is movably arranged on the base 100, it can be adaptively movable, so that the impact force of the vehicle 30 can be avoided to a certain extent to hit the conductive part 200, causing damage to the conductive part 200.

[0042] The power receiving device 20 is electrically connected to the electrical equipment on the vehicle 30. After the conductive part 200 is connected to the power receiving device 20, the electrical equipment on the vehicle 30 can be powered by the power receiving device 20. For example, when loading and unloading, the vehicle 30 needs to open or close the door. The vehicle 30 has a gas circuit system for controlling the opening and closing of the door. The gas circuit system includes a solenoid valve. The switch of the solenoid valve can control the opening and closing of the door. The power receiving device 20 can be connected to the solenoid valve, and the power supply device 10 can be set at the loading and unloading position of the vehicle 30. In this way, when the vehicle 30 arrives at the loading and unloading position, it will pass through the power supply device 10, so that the conductive part 200 is connected to the power receiving device 20 to power the solenoid valve, thereby realizing the opening and closing of the door and completing the loading and unloading.

[0043] The present application provides a power supply device 10, in which the conductive part 200 can be switched to the power supply position in response to the vehicle 30 passing through the power supply device 10 to connect with the power receiving device 20 on the vehicle 30. Therefore, the vehicle 30 only needs to pass through the power supply device 10 to connect with the power receiving device 20 on the vehicle 30, so as to supply power to the electrical equipment on the vehicle 30 without stopping the vehicle 30 for manual operation, thereby greatly improving work efficiency.

[0044] It should be noted that the vehicle 30 to be charged needs to slow down appropriately before passing the power supply device 10. The conductive part 200 is connected to the power receiving device 20 on the vehicle 30. During the process of supplying power to the electrical equipment, the vehicle 30 needs to travel at a uniform and slow speed to ensure stable power supply between the conductive part 200 and the power receiving device 20.

[0045] In some embodiments, the base 100 includes a supporting unit 110, a rotating unit 120 and an installing unit 130, the rotating unit 120 is rotatably disposed at the top of the supporting unit 110, the installing unit 130 is connected to the side of the rotating unit 120, and the conductive part 200 is movably disposed on the installing unit 130.

[0046] The support unit 110 is used to support the rotating unit 120 and the mounting unit 130, and can be installed on the ground. Since the rotating unit 120 is rotatably arranged at the top of the support unit 110, the mounting unit 130 is connected to the side of the rotating unit 120, and the conductive part 200 is movably arranged on the mounting unit 130, the rotating unit 120 can drive the conductive part 200 to rotate through the mounting unit 130. Since the conductive part 200 is rotatable, when the conductive part 200 needs to be connected to the power receiving device 20 on the passing vehicle 30, the conductive part 200 can be rotated to a suitable position to accurately dock with the power receiving device 20.

[0047] Specifically, the support unit 110 includes a base 111 and a support rod 112 installed on the base 111. The base 111 is set on the ground. The rotating unit 120 is rotatably set on the top of the support rod 112. The height of the support rod 112 needs to be basically the same as the height of the power receiving device 20 from the ground, so that the conductive part 200 can be aligned with the power receiving device 20 and achieve connection.

[0048] In some embodiments, the rotating unit 120 can drive the conductive part 200 to rotate through the mounting unit 130 so that the conductive part 200 can be switched between the standby position and the power supply position.

[0049] That is, when the power supply device 10 is not charging, the conductive part 200 is located in the standby position. When the power supply device 10 needs to supply power, the rotating unit 120 drives the conductive part 200 to rotate to the power supply position through the mounting unit 130 to connect with the power receiving device 20. After charging is completed, the rotating unit 120 drives the conductive part 200 to rotate back to the standby position through the mounting unit 130.

[0050] Specifically, the conductive part 200 can be arranged horizontally, and the position of the conductive part 200 when it is parallel to the railway is the standby position, and the position of the conductive part 200 when it is perpendicular to the railway is the power supply position. Since the conductive part 200 is parallel to the railway when the power supply device 10 does not need to be charged, the conductive part 200 will not interfere with the operation of the railway, and when the power supply device 10 needs to be charged, the conductive part 200 is perpendicular to the railway, intruding the boundary of the railway, and can be conveniently connected to the power receiving device 20 on the vehicle 30.

[0051] It should be noted that the power supply device 10 also includes a control system 500, which has the ability to collect multi-channel sensors, has the ability to operate IO modules, drive motor loads and remote communication, and has human-computer interaction functions. The control system 500 is electrically connected to the rotating unit 120, and a button for operating the rotating unit 120 can be set on the control system 500. When the vehicle 30 to be charged is about to reach the power supply device 10, the rotating unit 120 can drive the conductive part 200 to rotate to the power supply position through the mounting unit 130 by pressing the button, so that when the vehicle 30 passes through the power supply device 10, the conductive part 200 can be connected to the power receiving device 20. When the vehicle 30 is fully charged and leaves the power supply device 10, the button can be pressed again, so that the rotating unit 120 drives the conductive part 200 to rotate back to the standby position through the mounting unit 130.

[0052] Of course, the rotating unit 120 may also be operated by a wireless remote controller or controlled by remote communication, and there is no limitation to this.

[0053] Furthermore, in order to improve the integration of the power supply device 10 and to facilitate the connection between the rotating unit 120 and the control system 500 , the control system 500 may be installed on the supporting unit 110 .

[0054] In some embodiments, the mounting unit 130 includes a mounting bracket 131 and an elastic element 132 disposed on the mounting bracket 131 , the mounting bracket 131 is connected to a side of the rotating unit 120 , and the conductive part 200 is installed in the elastic element 132 .

[0055] The elastic element 132 is elastic, and the conductive part 200 is installed in the elastic element 132, that is, the conductive part 200 is movably arranged on the installation unit 130. When the vehicle 30 passes the power supply device 10, the conductive part 200 will contact the power receiving device 20 to achieve connection. Since the vehicle 30 keeps moving slowly during the process of the conductive part 200 contacting the power receiving device 20, the power receiving device 20 is also in a moving state, so the power receiving device 20 will drive the elastic element 132 to deform within the tolerable range. When the vehicle 30 leaves the power supply device 10, the elastic element 132 returns to its initial state and drives the conductive part 200 back to its initial position.

[0056] Specifically, the elastic element 132 can be a travel switch, and the conductive part 200 is installed on the push rod of the travel switch. The structure of the travel switch is a prior art and will not be described in detail here. It should be explained that here, the structure of the travel switch is used to provide an elastic range of motion for the conductive part 200, but the travel switch and the conductive part 200 are insulated.

[0057] The mounting bracket 131 includes a first mounting member 131a and a second mounting member 131b which are vertically arranged. The first mounting member 131a is connected to the rotating unit 120, and the elastic element 132 is installed on the second mounting member 131b. In order to enhance the structural strength of the mounting bracket 131, a reinforcing member 131c is provided between the elastic elements 132.

[0058] In some embodiments, when the conductive portion 200 is located at the power supply position and the elastic element 132 is deformed, the conductive portion 200 is charged.

[0059] In order to save power and for safety considerations, the conductive part 200 is not energized when the power supply device 10 is not supplying power, and the conductive part 200 is energized only when the power supply device 10 needs to supply power. The conductive part 200 can be connected to the control system 500, and the control system 500 sends a power-on command or a power-off command to the conductive part 200, so that the conductive part 200 is energized or de-energized.

[0060] The rotating unit 120 will drive the conductive part 200 to rotate to the power supply position only after responding to the power supply instruction, so as to prepare for connection with the power receiving device 20, and during the contact between the conductive part 200 and the power receiving device 20, the elastic element 132 will be deformed. Therefore, when the conductive part 200 is in the power supply position and when the elastic element 132 is deformed, it means that the power supply device 10 has a power supply demand and the conductive part 200 has been in contact with the power receiving device 20. Therefore, the control system 500 needs to control the conductive part 200 to obtain power to power the power-consuming device.

[0061] Specifically, the control system 500 is also electrically connected to the elastic element 132. When the rotating unit 120 drives the conductive part 200 to rotate to the power supply position and the elastic element 132 is deformed, the control system 500 controls the conductive part 200 to be powered; when the rotating unit 120 drives the conductive part 200 to rotate to the standby position and the elastic element 132 restores its deformation, the control system 500 controls the conductive part 200 to lose power.

[0062] In some embodiments, the rotating unit 120 includes a rotating member 121 and a connecting member 122 , the rotating member 121 is disposed on the top of the supporting unit 110 , the connecting member 122 is connected to the side of the rotating member 121 , and the mounting unit 130 is connected to the connecting member 122 .

[0063] The rotating member 121 is a rotatable device. Since the connecting member 122 is connected to the side of the rotating member 121 and the mounting unit 130 is connected to the connecting member 122, the rotating member 121 can drive the mounting unit 130 to rotate through the connecting member 122, thereby driving the conductive part 200 to rotate. The rotating member 121 is electrically connected to the control system 500. When the rotating member 121 drives the conductive part 200 to rotate to the power supply position or the standby position, the rotating member 121 sends a rotation position signal to the control system 500. Specifically, the rotating member 121 can be a universal swivel joint.

[0064] In some embodiments, the conductive part 200 includes at least one pair of electrodes 210. Obviously, the pair of electrodes 210 includes a positive electrode 210 and a negative electrode 210. The elastic elements 132 are arranged in a one-to-one correspondence with the electrodes 210, and each electrode 210 is installed in the corresponding elastic element 132. The electrodes 210 can be arranged in one pair, two pairs, or multiple pairs, without limitation.

[0065] Based on the same inventive concept, please refer to Figure 1-Figure 3 The embodiment of the present application further provides a power supply system, including a power receiving device 20 and the above-mentioned power supply device 10. The beneficial effects of the power supply system provided by the embodiment of the present application are the same as the beneficial effects of the above-mentioned power supply device 10, which will not be repeated here.

[0066] In some embodiments, the power receiving device 20 includes a main body 300 and a power shock plate 400 disposed on the main body 300 , the main body 300 is connected to the side of the vehicle 30 , the power shock plate 400 is electrically connected to the electrical equipment on the vehicle 30 , and the power shock plate 400 is used to connect to the conductive part 200 .

[0067] When the vehicle 30 passes through the power supply device 10, the electric shock plate 400 contacts the conductive part 200 to achieve electrical connection. Of course, since the vehicle 30 keeps moving during the charging process, the electric shock plate 400 and the conductive part 200 will rub against each other. Over time, scratches of the conductive part 200 will be left on the electric shock plate 400. Therefore, the electric shock plate 400 needs to be made of a conductive material with a certain strength to extend the service life of the electric shock plate 400.

[0068] Specifically, the electric shock plate 400 can be made of steel, which is conductive and has a certain strength. The electric shock plate 400 can be electrically connected to the electrical equipment on the vehicle 30 through the wire 410. The main body 300 can be made of non-conductive materials such as wood or plastic to prevent current from entering the main body 300 and causing current waste.

[0069] In some embodiments, there are multiple electrically shocked plates 400 , and the multiple electrically shocked plates 400 are arranged at intervals along the vertical direction; the conductive part 200 includes at least one pair of electrodes 210 , and at least one pair of electrodes 210 are arranged at intervals along the vertical direction, and each electrode 210 can selectively contact one of the electrically shocked plates 400 .

[0070] Each electric shock plate 400 is connected to a different electrical device, and each electrode 210 can selectively contact one of the electric shock plates 400 to supply power to different electrical devices and realize different functions. Therefore, the electric shock plate 400 to be connected can be selected according to needs. Taking the control of the opening and closing of the car door as an example, four electric shock plates 400 can be arranged vertically. From top to bottom, when a pair of electrodes 210 contact the two upper electric shock plates 400 respectively, the car door is opened; when the above pair of electrodes 210 contact the two lower electric shock plates 400 respectively, the car door is closed.

[0071] In some embodiments, the conductive portion 200 may be vertically slidably disposed on the base 100 .

[0072] Each electrode 210 can selectively contact one of the electric shock plates 400 by sliding. Specifically, the position of the electric shock plate 400 is fixed, and the electrode 210 can be slid to be arranged corresponding to the corresponding electric shock plate 400, so that when the vehicle 30 passes the power supply device 10, the electrode 210 can contact the corresponding electric shock plate 400 to achieve the corresponding function. Taking the control of the opening and closing of the door as an example, four electric shock plates 400 can be arranged vertically. From top to bottom, when a pair of electrodes 210 contact the two upper electric shock plates 400 respectively, the door is opened; when the above pair of electrodes 210 move downward to contact the two lower electric shock plates 400 respectively, the door is closed.

[0073] In some embodiments, see Figure 2 and Figure 4 A guide rail 131d is provided on the base 100, and the electrode 210 is slidably disposed in the guide rail 131d. A fixing piece is provided on the electrode 210, and the fixing piece detachably connects the electrode 210 and the guide rail 131d.

[0074] The guide rail 131d is vertically arranged on the base 100, and the electrode 210 is slidably arranged in the guide rail 131d, so that the electrode 210 can be slidably arranged on the base 100 vertically. When the electrode 210 slides into place, the sliding member and the guide rail 131d are connected by a fixing member, so that the conductive part 200 can be fixed to the base 100. When the electrode 210 needs to slide again to dock with other electric shock plates 400, the fixing member can be removed.

[0075] Specifically, the guide rail 131d is provided on the second mounting member 131b, the elastic element 132 and the electrode 210 are arranged one by one, each electrode 210 is installed in the corresponding elastic element 132, and the elastic element 132 is slidably arranged in the guide rail 131d, and the fixing member can be arranged on the elastic element 132. The fixing member can be a bolt and a nut, that is, the elastic element 132 and the second mounting member 131b can be provided with coaxial through holes, the bolt is arranged in the through hole, the nut abuts against the second mounting member 131b and is screwed with the bolt to achieve the connection between the elastic element 132 and the guide rail 131d.

[0076] Furthermore, since both the electrode 210 and the elastic element 132 need to be connected to the control system 500 via the wire 410, the second mounting member 131b is further provided with a wire hole 131e for passing the wire 410, and the wire hole 131e can be disposed between the guide rails 131d.

[0077] Based on the same inventive concept, please refer to Figure 1 and Figure 2 The embodiment of the present application also provides a power supply method, which is implemented based on the power supply device 10 described above. The beneficial effects of the power supply method provided by the embodiment of the present application are the same as the beneficial effects of the power supply device 10 described above, which will not be repeated here. Figure 5 , the method comprising:

[0078] S100: In response to a power supply instruction, the conductive part 200 is controlled to switch to a power supply position.

[0079] When the vehicle 30 to be charged is about to pass the power supply device 10, a power supply instruction can be issued by pressing a button on the control system 500, operating a wireless remote control, or controlling the rotating unit 120 through remote communication. The control system 500 responds to the power supply instruction, that is, controls the conductive part 200 to switch to the power supply position to prepare for charging.

[0080] S200: Determine whether the conductive part 200 is in contact with the power receiving device 20. If so, control the conductive part 200 to receive power.

[0081] When the conductive part 200 contacts the power receiving device 20, it means that the charging condition is met, so the control system 500 controls the conductive part 200 to be powered, so that the conductive part 200 and the power receiving device 20 are powered, thereby supplying power to the power-consuming device. If the conductive part 200 does not contact the power receiving device 20, it means that the power receiving device 20 has not yet reached the power supply device 10.

[0082] S300: Determine whether the conductive part 200 is separated from the power receiving device 20. If so, control the conductive part 200 to switch to the standby position and control the conductive part 200 to lose power.

[0083] Since the vehicle 30 keeps traveling at a low speed while the conductive part 200 is in contact with the power receiving device 20, when the vehicle 30 leaves the power supply device 10, the conductive part 200 is separated from the power receiving device 20, indicating that charging is completed. Therefore, the control system 500 controls the conductive part 200 to switch to the standby position to prevent the conductive part 200 from interfering with the railway operation, and controls the conductive part 200 to lose power to save power and ensure safety.

[0084] Based on the same inventive concept, the embodiment of the present application also provides a power supply method, which is implemented based on the power supply device 10 described above. The beneficial effects of the power supply method provided by the embodiment of the present application are the same as the beneficial effects of the power supply device 10 described above, which will not be repeated here. Figure 6 , the method comprising:

[0085] S400: In response to the power supply instruction, the conductive part 200 is controlled to switch to the power supply position.

[0086] When the vehicle 30 to be charged is about to pass the power supply device 10, a power supply instruction can be issued by pressing a button on the control system 500, operating a wireless remote control, or controlling the rotating unit 120 through remote communication. The control system 500 responds to the power supply instruction, that is, controls the conductive part 200 to switch to the power supply position to prepare for charging.

[0087] S500: Determine whether the elastic element 132 is deformed, and if so, control the electrode 210 to be energized.

[0088] When the elastic element 132 is deformed, it means that the conductive part 200 has contacted the power receiving device 20, and the charging condition is met at this time. Therefore, the control system 500 controls the conductive part 200 to be energized so that the conductive part 200 and the power receiving device 20 are energized, thereby supplying power to the electrical device. If the elastic element 132 is not deformed, it means that the conductive part 200 has not contacted the power receiving device 20, and the power receiving device 20 has not yet reached the power supply device 10.

[0089] S600: Determine whether the elastic element 132 recovers its deformation. If so, control the conductive part 200 to switch to the standby position and control the conductive part 200 to lose power.

[0090] Since the vehicle 30 keeps traveling at a low speed during the contact between the conductive part 200 and the power receiving device 20, when the vehicle 30 leaves the power supply device 10 and the conductive part 200 is separated from the power receiving device 20, the elastic element 132 will restore its deformation, and the charging is completed at this time. Therefore, the control system 500 controls the conductive part 200 to switch to the standby position to prevent the conductive part 200 from interfering with the railway operation, and controls the conductive part 200 to lose power to save power and ensure safety.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the present invention.

[0092] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
