Description

Technical Field

[0001] The present invention relates to the field of charging piles, and particularly to a channel connector and a PDU system. Background Art

[0002] With the increasing support from the state for the new energy field year by year, the popularity of electric vehicles is also growing day by day. As the charging facilities for electric vehicles, more and more charging devices appear in people's daily lives. Existing charging devices are mainly divided into AC charging piles and DC charging piles. Among them, due to the large power of DC charging piles, they can meet the urgent need for emergency charging of electric vehicles. However, in the actual use scenarios of charging stations, there are rarely situations where all charging piles need to operate at full load. At the same time, short-term large power fluctuations will affect the power supply network. Currently, many companies have started to research and manufacture charging stacks that can perform power distribution. In the flexible power distribution system of existing charging stacks, the core unit is the PDU. As the intermediate hub between the power supply and the charging terminal, the PDU plays a role in connection and distribution. The existing channel selector PDU system has the following problems:

[0003] 1. Relay or switch is used for flexible power distribution. For M charging modules with N outputs, 2×M×N relays or switches need to be configured. Adding one output requires adding many relays or switches, and the scalability is poor.

[0004] 2. When adding relays or switches, corresponding heat dissipation devices also need to be considered, which will increase the space and cost.

[0005] 3. After the relay or switch is expanded, the overall circuit becomes very complex, the process is cumbersome, and it is not conducive to the later maintenance cost. Summary of the Invention

[0015] A PDU system includes the above-mentioned channel connector.

[0016] Based on the above structure, the technical effects that the present invention can achieve are:

[0017] 1. The channel connector of the present invention includes a mounting base, a conductive member, and a driving module. The mounting base is arranged in a ring shape, and a wiring assembly is provided on the mounting base along the circumferential direction. The wiring assembly includes at least one set of wiring posts and an arc-shaped wiring groove. The wiring posts are arranged around the arc-shaped wiring groove. Conductive contacts are provided at both ends of the conductive member. The driving module is connected to the conductive member. The driving module drives the conductive member to rotate and move up and down, so that any one of the wiring posts forms an electrical connection with the arc-shaped wiring groove through the conductive member. In this way, the connection between one power supply device and multiple power receiving devices, or multiple power supply devices and one power receiving device can be realized, thereby realizing power distribution. In the prior art, power supply distribution is achieved through a relay group, resulting in a large number of relays, occupying a large space, and complex wiring. In this application, the relays are integrally installed on the ring-shaped mounting base, so that the external wiring of the channel connector is reduced, making the channel connector simple in structure and good in scalability.

[0018] 2. Two sets of wiring assemblies and two sets of conductive members are provided on the mounting base of the channel connector of the present invention. In this way, the positive and negative relays of the channel connector can be installed on one mounting base, reducing one set of mounting structures and simplifying the structure of the channel connector.

[0019] 3. The driving module of the present invention includes a fixing frame, a lifting module, and a rotating module. The fixing frame is fixedly assembled along the central axial direction of the mounting base. The driving end of the lifting module is fixedly assembled at one end of the fixing frame. The non-driving end of the lifting module passes through the fixing frame and is connected to the mounting base. The rotating module is sleeved on the fixing frame. In the circumferential direction, the rotating module is in clearance fit with the fixing frame. The lifting module drives the rotating module to move up and down by means of a connecting member.

In this application, the pair of sensors and the code disk are used to detect the rotation in place. At the same time, the driving module for driving the second bearing can also detect the rotation in place. By setting two sets of sensor systems to check errors with each other, the reliability of the channel connector is ensured.

Detailed implementation manner

[0034] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually illustrative only and in no way limits the present invention and its application or use. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0035] It should be noted that the terms used here are only for describing the specific implementation manners and are not intended to limit the exemplary embodiments according to the present application. As used here, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "include" and / or "comprise" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0036] Unless otherwise specifically stated, the relative arrangements, numerical expressions, and numerical values of the components and steps described in these embodiments do not limit the scope of the present invention. At the same time, it should be understood that for the sake of description, the dimensions of the various parts shown in the drawings are not drawn in actual proportional relationships. Technologies, methods, and devices known to those of ordinary skill in the relevant fields may not be discussed in detail, but where appropriate, the technologies, methods, and devices should be regarded as part of the authorization specification. In all the examples shown and discussed here, any specific value should be interpreted as merely exemplary and not as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar reference numerals and letters indicate similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further discussed in the subsequent drawings.

[0037] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by orientation words such as "front, back, up, down, left, right", "horizontal, vertical, perpendicular, horizontal" and "top, bottom", etc. is usually based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description. Without contrary explanation, these orientation words do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation on the protection scope of the present invention; the orientation words "inside, outside" refer to the inside and outside relative to the contour of each component itself.

[0038] For the convenience of description, spatial relative terms such as "above...", "over...", "on the upper surface of...", "upper" etc. can be used here to describe the spatial positional relationship between a device or feature shown in the figure and other devices or features. It should be understood that the spatial relative terms are intended to include different orientations in use or operation in addition to the orientation described in the figure for the device. For example, if the device in the drawing is inverted, the device described as "above other devices or structures" or "over other devices or structures" will then be positioned as "below other devices or structures" or "under other devices or structures". Thus, the exemplary term "above..." can include both the orientations of "above..." and "below...". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and corresponding interpretations are made for the spatial relative descriptions used here.

[0039] In addition, it should be noted that using words such as "first", "second" etc. to limit components is only for the convenience of differentiating the corresponding components. Without additional statement, the above words have no special meaning. Therefore, it should not be construed as a limitation on the protection scope of the present invention.

[0040] As Figure 1 shown, in the prior art, each power module is connected to the device where the charging gun is located by means of N positive relays and N negative relays. When the large current charging is required by the power receiving device, M power modules are needed to supply power to the device where a charging gun is located. In this way, the entire power supply device requires 2×M×N relays, and at the same time, a large number of wires are needed to connect the power modules, relays and the charging gun. This makes the circuit of the power supply device and the PDU system complex, with poor scalability, not conducive to later maintenance, and also increases the cost.

[0041] As Figures 2 - 10As shown in the figure, the channel connector of this embodiment includes a mounting base 1, a conductive member 2, and a driving module 3. The mounting base 1 is arranged in a ring shape. Along the circumferential direction of the mounting base 1, there is a wiring assembly 11. The wiring assembly 11 includes at least one set of terminal posts 111 and an arc-shaped wiring groove 112. In this embodiment, the number of terminal posts 111 is set to 12. The terminal posts 111 are arranged around the arc-shaped wiring groove 112. Both ends of the conductive member 2 are provided with conductive contacts 21. The driving module 3 is connected to the conductive member 2. The driving module 3 drives the conductive member 2 to perform rotational and lifting movements, so that any one of the terminal posts 111 forms an electrical connection with the arc-shaped wiring groove 112 by means of the conductive member 2.

[0042] As can be seen from the above, in this embodiment, multiple conductive terminal posts 111 and arc-shaped wiring grooves 112 are integrally installed together, reducing the space occupied and making the structure of the channel connector compact. One end of the power module contacts the arc-shaped wiring groove 112, and then slides on the arc-shaped wiring groove 112 through the conductive member 2 to form electrical connections with each terminal post 111. The other ends of the multiple terminal posts 111 are respectively connected to each power receiving device. At the same time, in this embodiment, the connection wires between the power module and each relay are reduced, and the connection wires between the relay and the charging gun are also reduced. In this way, the circuit of the channel connector is simple, the structure is simple and compact, and the expandability of the power supply device is improved.

[0043] As Figure 4 、 5 shown in the figure, the mounting base 1 of this embodiment is provided with a wiring assembly 11. Specifically, the mounting base 1 forms multiple terminal posts 111 along the circumferential direction. Mounting holes are formed on the terminal posts 111, and electrodes 12 are inserted into the mounting holes. An arc-shaped conductive ring 13 is assembled in the arc-shaped wiring groove 112. The arc-shaped conductive ring 13 can also be embedded in the bottom of the arc-shaped wiring groove 112, so that the conductive contacts 21 at both ends of the conductive member 2 are respectively in contact with the electrode 12 and the arc-shaped conductive ring 1, enabling the terminal post 111 and the arc-shaped wiring groove 112 to form an electrical connection.

[0044] Furthermore, the end face of the electrode 12 in this embodiment is lower than the end face of the terminal post 111. In this way, the conductive contact 21 needs to extend into the terminal post 111 to form an electrical connection with the electrode 12. In this way, the arc connection between adjacent terminal posts 111 is blocked, thus ensuring the electrical safety distance.

[0045] Preferably, a guiding member 1111 is formed on the terminal post 111. The guiding member 1111 is inclined, so as to facilitate the insertion of the conductive contact 21 into the terminal post 111 to form an electrical connection with the electrode 12.

[0046] Preferably, multiple electrodes 12 in this embodiment are installed on an electrode base 121 and then inserted into the terminal posts 111.

[0047] According to the preferred technical solution of the present invention, asFigure 2 , 4 As shown in 4 , the channel connector of this embodiment includes two sets of wiring components 11 and two sets of conductive members 2. The two sets of wiring components 11 are arranged on the mounting base 1, and the two sets of wiring components 11 are symmetrically distributed relative to the center of the annular mounting base 1. The two sets of conductive members 2 form an integral body by means of the fixing base 22. In this way, it can be ensured that the two sets of conductive members 2 move in the same manner relative to the two sets of wiring components 11.

[0048] Furthermore, the channel connector of this embodiment further includes a cover shell 5. The cover shell 5 is fixedly connected to the mounting base 1 and forms a closed space with the mounting base 1, which can play roles such as dust-proof and waterproof.

[0049] As Figure 5 shown in Figure 5 , the conductive member 2 of this embodiment is rotationally matched with the fixing base 22 so that the conductive member 2 forms an electrical connection with the wiring component 11. Specifically, the fixing base 22 is annular, and a mounting member is formed on the fixing base 22. A U-shaped notch 222 is formed on the mounting member. The middle part of the conductive member 2 is rotationally connected to the U-shaped notch 222 by means of a rotating shaft. When the two conductive contacts 21 at both ends of the conductive member 2 are in contact with the electrode 12 and the arc-shaped conductive ring 13 respectively, if the contact surfaces of the electrode 12 and the arc-shaped conductive ring 13 are not at the same height, that is, one conductive contact 21 contacts the electrode 12 first, the conductive member 2 can rotate around the rotating shaft so that the other conductive contact 21 contacts the arc-shaped conductive ring 13. In addition, limiting members 23 extend from both sides of the conductive member 2. When the conductive member 2 rotates around the rotating shaft, the limiting members 23 can abut against the U-shaped notch 222 to limit the rotation angle of the conductive member 2. Preferably, limiting surfaces 221 are formed on both sides of the fixing base 22.

[0050] As Figure 6 shown in Figure 6 , the drive module 3 of this embodiment includes a fixing frame 31, a lifting module 32 and a rotating module 33. The lifting module 32 and the rotating module 33 are connected together by means of the fixing frame 31. Specifically, the fixing frame 31 is fixedly assembled along the central axial direction of the mounting base 1. An accommodating space is formed inside the fixing frame 31. A connecting member 34 is assembled in the accommodating space. The driving end of the lifting module 32 is fixedly assembled at one end of the fixing frame 31. The non-driving end of the lifting module 32 passes through the connecting member 34 and the accommodating space and is connected to the mounting base 1. The rotating module 33 is sleeved on the fixing frame 31. In the circumferential direction, the rotating module 33 is in clearance fit with the fixing frame 31. The connecting member 34 is assembled along the axial direction perpendicular to the fixing frame 31. Both ends of the connecting member 34 are fixedly connected to the rotating module 33. In this way, the lifting module 32 can drive the rotating module 33 to perform a lifting movement by means of the connecting member 34.

[0051] As Figure 2 and 8As shown, the lifting module 32 of this embodiment drives the conductive member 2 to move up and down along the axial direction of the fixed frame 31. Specifically, the lifting module 32 includes a first driving member 321 and a screw-nut kinematic pair 322. The first driving member 321 is fixedly assembled on the fixed frame 31. The screw-nut kinematic pair 322 includes a screw 3221 and a nut 3222. One end of the screw 3221 is connected to the driving end of the first driving member 321, and the other end of the screw 3221 is connected to the mounting seat 1. The nut 3222 is fixedly connected to the connecting member 34, and the connecting member 34 is connected to the conductive member 2 by means of a rotating module 33. When the first driving member 321 rotates forward, the screw 3221 rotates forward accordingly, and the nut 3222 drives the conductive member 2 to move downward along the vertical direction. When the first driving member 321 rotates reversely, the screw 3221 rotates reversely accordingly, and the nut 3222 drives the conductive member 2 to move upward along the vertical direction. The first driving member 321 can be, but is not limited to, a motor, as long as it can drive the screw 3221 to rotate.

[0052] As Figure 2 and 9 shown, the rotating module 33 of this embodiment drives the conductive member 2 to rotate so that the conductive member 2 corresponds to the position of any one of the terminal posts 111. Specifically, the rotating module 33 includes a first bearing 331, a second bearing 332, and a second driving member 333. The outer ring of the first bearing 331 is rotationally assembled with the connecting member 34, and the inner ring of the first bearing 331 is slidably assembled with the guide rod 311 on the connecting member 34. The inner ring of the second bearing 332 is fixedly connected to one end of the connecting member 34, and the outer ring of the second bearing 332 is provided with a gear ring 334. The inner rings of the first bearings 331 at both ends of the connecting member 34 are fixedly connected. The driving end of the second driving member 333 is provided with a gear 335 passing through the connecting plate. One end of the connecting plate is fixedly connected to the connecting member 34. The second driving member 333 drives the gear 335 to rotate, and drives the rotation of the gear ring 334 and the outer ring of the second bearing 332 thereon through gear teeth meshing. Since the conductive member 2 is connected to the outer ring of the second bearing 332 by means of the fixed seat 22, the rotation of the outer ring drives the fixed seat 22 and the conductive member 2 to rotate accordingly. Thus, it can be rotated to the position of any one of the terminal posts 111 as needed. When the second driving member 333 stops working, the conductive member 2 stops rotating, so that the conductive member 2 corresponds to the position of the terminal post 111. The second driving member 333 can be, but is not limited to, a motor, as long as it can drive the gear to rotate.

[0053] Further, as Figure 10As shown, the second bearing 332 of this embodiment is fixedly connected by means of a balance ring 6 and a fixed seat 22. One side of the balance ring 6 is fixedly connected to the outer ring of the second bearing 332. A limiting protrusion 61 corresponding to the limiting surface 221 extends from the non-fixed side of the balance ring 6. The limiting protrusion 61 is inserted and matched with the limiting surface 221. In this way, when the conductive members 2 at both ends of the fixed seat 22 come into contact with the wiring assembly 11, the forces received are different, and the fixed seat 22 can slide on the balance ring 6 to ensure that the conductive members 2 at both ends of the fixed seat 22 are in contact with the wiring assembly 11.

[0054] According to the preferred technical solution of the present invention, as Figure 7 and 9 shown, a code disk 336 is provided on one side of the outer ring of the second bearing 332 in this embodiment. Grooves are formed on the code disk 336, and the positions of the grooves correspond to the positions of the wiring posts 111. A positioning sensor 41 is provided at one end of the connecting member 34. The position of the groove can be detected by the positioning sensor 41 to determine that the second bearing 332 rotates in place. At the same time, the second driving member 333 that drives the second bearing 332 can also detect the rotation in place. By setting two sets of detection systems to check errors with each other, the reliability of the channel connector is ensured.

[0055] To improve the reliability of the channel connector, the channel connector of this embodiment further includes an electronic control module 4. The electronic control module 4 is arranged in the accommodation space of the fixing frame 31. The electronic control module 4 includes a temperature sensor, a position-in-place sensor, and a limit sensor. The position-in-place sensor is arranged at the starting point and the end point of the lifting movement and is used to detect whether the lifting movement of the lifting module 32 reaches the starting point or the end point position. The limit sensor is arranged at both ends of the total stroke of the rotational movement and is used to prevent the rotational movement of the rotational module 33 from exceeding the stroke. The position-in-place sensor and the limit sensor can both adopt proximity switches, such as a combination of one or more of a photoelectric switch, a microswitch, a Hall sensor, etc. The difference lies in the different setting positions.

[0056] Among them, the temperature sensor is set as a contact temperature sensor. The contact temperature sensor can be arranged on the conductive member 2. The contact temperature sensor can detect the temperature near the contact point, mainly used to ensure the reliability of the contact of the contact point and the normal contact resistance. For the contact temperature sensors at both contact ends, theoretically, the temperature rise should be basically the same. If the deviation is too large, either there is a problem with the contact point or there is a problem with the sensor, which belongs to an abnormality and requires an alarm and stop working. The contact temperature sensor can use a thermal resistor, a thermocouple, etc.

[0057] Based on the above channel connector, this embodiment also proposes a PDU system. Through this channel connector, the circuit of the PDU system is simple, the structure is compact, and the expandability is strong.

[0058] Based on the above structure, the working principle of the channel connector and the PDU system of this embodiment is as follows:

[0059] When charging is required, the second driving member 333 drives the gear 335 to rotate. Through the meshing of the gear teeth, the gear ring 334 and the outer ring of the second bearing 332 thereon are driven to rotate. In this way, the conductive member 2 rotates accordingly. Thus, it can be rotated to any one of the terminal posts 111 as required. Then the second driving member 333 stops working and the conductive member 2 stops rotating. Further, the position of the conductive member 2 corresponds to the terminal post 111. The first driving member 321 drives the lead screw 3221 to rotate forward. At the same time, the nut 3222 on the lead screw 3221 drives the connecting member 34 and the device thereon to move towards the terminal post 111, so that the conductive contact 21 contacts and is electrically connected to the corresponding electrode 12 and the arc-shaped conductive ring 13, in order to supply power to the power receiving device.

[0060] When power needs to be supplied to another power receiving device, the first driving member 321 drives the lead screw 3221 to rotate in the reverse direction. At the same time, the nut 3222 on the lead screw 3221 drives the connecting member 34 and the device thereon to move away from the terminal post 111, so that the conductive contact 21 is separated from the corresponding electrode 12 and the arc-shaped conductive ring 13. The first driving member 321 stops working. The second driving member 333 drives the gear 335 to rotate. Through the meshing of the gear teeth, the gear ring 334 and the outer ring of the second bearing 332 thereon are driven to rotate. In this way, the conductive member 2 rotates accordingly. It is rotated to another terminal post 111 as required. Then the second driving member 333 stops working and the conductive member 2 stops rotating. Further, the position of the conductive member 2 corresponds to the terminal post 111. The first driving member 321 drives the lead screw 3221 to rotate forward. At the same time, the nut 3222 on the lead screw 3221 drives the connecting member 34 and the device thereon to move towards the terminal post 111, so that the conductive contact 21 contacts and is electrically connected to the corresponding electrode 12 and the arc-shaped conductive ring 13, in order to supply power to the power receiving device.

[0061] The embodiments of the present invention have been described in detail above in conjunction with the accompanying 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, various changes can be made without departing from the gist of the present invention.
