Description

Technical Field

[0001] The present invention relates to the technical field of charging devices, and particularly relates to a channel selector and a power distributor. Background Art

[0002] In recent years, with the encouragement of the country's new infrastructure construction and the development of new energy vehicles, the charging devices for electric vehicles, as an important item, have been continuously developing and growing; currently, charging devices are divided into DC charging and AC charging. Due to the long AC charging time, many charging stations choose DC charging devices more. DC charging devices are further divided into single-gun and multi-gun. The single-gun charging device supplies all the internal modules of the charging device to one gun at the same time, with high efficiency. However, if the charging station needs to increase the number of guns, more charging devices need to be invested, and the price is relatively high. For the multi-gun charging device, power distribution is generally achieved by connecting several contactors in series and parallel. This method cannot fully dispatch a single module; or the method of using an array relay is adopted. This method has a high cost, complex circuits, and it is easy for workers to connect wrongly, and subsequent maintenance is also more complex.

[0003] In the existing flexible power distribution system of a charging stack, the core unit PDU adopts a single relay / contactor to form an MxN array method, or adopts a method of multiple fixed multi-contact relays / contacts. Essentially, they are all an MxN relay group in an array form. The disadvantage of directly adopting a relay array is that the number of relays used is large, the cost is high, and MxN complex control circuits are required. This solution is quite complex in terms of structure, electricity, hardware, and software. Adopting a customized multi-channel relay can simplify the high-voltage circuit and structure, but it cannot simplify the control circuit, and the cost becomes higher. The number of channels of the customized multi-channel relay is fixed, and channel expansion cannot be carried out. When multiple powers are concentrated on one multi-channel relay, the heat generation of a single multi-channel relay is high. Summary of the Invention

[0004] In order to solve the technical problem in the prior art that the charging stack adopts a relay, which requires fixed wiring and has poor flexibility, the present invention provides a channel selector and a power distributor, which solve the above technical problems. The technical solution of the present invention is as follows:

[0005] A channel selector includes: a moving carrier, which is slidably assembled, and the moving carrier has an opening; a conductive module, the first end of the conductive module is slidably assembled in the moving carrier, and the second end of the conductive module is provided with a conductive member; a linear module, which is assembled on the moving carrier, and the linear module first drives the second end of the conductive module to extend out of the moving carrier, and then expands the conductive member outwards to connect to an external channel.

[0006] The channel selector of the present invention includes a moving carrier and a conductive module. The moving carrier can drive the conductive module to slide to the working position, and then the linear module drives the conductive module to extend out of the moving carrier and drives the conductive parts on the conductive module to expand outwards to connect to the external channel. That is, when moving to the working position, the conductive module can be at least partially contracted in the moving carrier and slide with the moving carrier, which can effectively avoid interference with the external channel; when moving to the working position, the conductive module can extend out of the moving carrier, and the conductive parts expand outwards to connect to the external channel. Compared with a relay, the channel selector of the present application does not require fixed wiring, has good flexibility and strong applicability.

[0007] According to an embodiment of the present invention, the linear module elastically drives the conductive module to slide along the moving carrier. When the conductive module is limited by the moving carrier, the linear module can drive the conductive parts to expand outwards.

[0008] According to an embodiment of the present invention, the linear module includes a screw rod and a nut sleeve that cooperate with each other. The screw rod rotates driven by a driving member and drives the nut sleeve to move telescopically along the screw rod. One end of the nut sleeve close to the screw rod acts on the conductive module through an elastic member, and the other end of the nut sleeve extends into the second end of the conductive module and is connected to the conductive part through a connecting rod assembly.

[0009] According to an embodiment of the present invention, there are two conductive parts. In the initial state, the conductive parts are embedded on the outer wall of the second end of the conductive module.

[0010] According to an embodiment of the present invention, two connecting parts are provided on each conductive part. The two connecting parts are respectively located on two mutually perpendicular outer surfaces of the conductive part, and the two connecting parts are arranged in an axial offset manner.

[0011] According to an embodiment of the present invention, the sliding direction of the conductive module in the moving carrier is perpendicular to the sliding direction of the moving carrier.

[0012] A power distributor includes: an external channel, the external channel includes a first channel and a second channel; a guide rail, the guide rail is arranged parallel to the first channel; a channel selector, the channel selector is correspondingly arranged with the first channel, the moving carrier of the channel selector slides along the guide rail to select the working position, and the first channel is electrically connected to the second channel through the channel selector.

[0013] According to an embodiment of the present invention, there is at least one group of the first channels, at least two groups of the second channels, the first channels are arranged in parallel, the second channels are arranged in parallel, and the first channels and the second channels are vertically staggered.

[0014] According to an embodiment of the present invention, the first channel includes two first copper bars arranged in parallel, the second channel includes two second copper bars arranged in parallel, the guide rail is located between the two first copper bars, and after the channel selector slides along the guide rail to the working position, it can extend between the two second copper bars of the second channel, and the conductor then expands outward to connect the first channel and the second channel.

[0015] According to an embodiment of the present invention, the first channel is an input channel, the second channel is an output channel, and the first channel is arranged on one side or both sides of the second channel.

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

[0017] 1. The channel selector of the present invention includes a moving carrier and a conductive module. The moving carrier can drive the conductive module to slide to the working position, and then the linear module drives the conductive module to extend out of the moving carrier and drives the conductive parts on the conductive module to expand outward to connect to the external channel. That is, when moving to the working position, the conductive module can be at least partially retracted in the moving carrier and slide with the moving carrier, which can effectively avoid interference with the external channel; when moving to the working position, the conductive module can extend out of the moving carrier, and the conductive parts expand outward to connect to the external channel. Compared with a relay, the channel selector of the present application does not require fixed wiring, has good flexibility and strong applicability;

[0018] 2. For the channel selector of the present invention, the linear module first drives the conductive module to extend out of the opening of the moving carrier, and then expands the conductive parts outward. One linear module can play the role of driving the expansion and contraction of the conductive module and expanding the conductive parts. The structure is simple and the driving is convenient; further setting the structure of the linear module, the nut sleeve moves linearly driven by the screw rod, and the nut sleeve elastically pushes the conductive module to extend outward along the moving carrier. When the wire module is limited by the opening of the moving carrier, the nut sleeve can continue to push the conductive parts outward, and the two connecting parts on the conductive parts can form an electrical connection with the external channel;

[0019] 3. For the channel selector of the present invention, in the initial state, the conductive parts are embedded on the outer wall of the second end of the conductive module, which can limit the conductive parts from further expanding and contracting, and only expand outward to connect to the external channel; further setting the two connecting parts on the conductive parts are respectively located on two mutually perpendicular outer surfaces of the conductive parts, and the two connecting parts are also arranged in an axial offset, which can facilitate the arrangement of the external channels and avoid the external channels from being unable to be arranged due to interference;

[0020] 4. The power distributor of the present invention can realize the selection and distribution of power by moving the channel selector along the guide rail to different working positions to connect the external first channel and the second channel;

[0021] 5. The power divider of the present invention can facilitate the movement of the channel selector to different working positions by setting the number and arrangement of the first channel and the second channel, enabling the establishment of electrical connections between the first channel and the second channel to form the selection and distribution of power. Further, by setting the relative positions of the guide rail and the external channel, the channel selector can slide along the guide rail parallel to the first channel. When the channel selector is not moved to the working position, the conductive module can be in a contracted state to avoid interference with the second channel. When the channel selector is moved to the working position, the conductive module extends, and the conductive part is expanded to make electrical connection with the external channel, with high overall integration and a compact structure.

[0032] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application.

At the same time, it should be understood that, for the sake of convenience of description, the dimensions of the various parts shown in the drawings are not drawn in actual proportional relationship.

In all the examples shown and discussed here, any specific value should be construed as merely exemplary and not as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that: like reference numerals and letters denote like items in the following drawings, and thus, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0034] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by orientation words such as "front, rear, upper, lower, left, right", "lateral, vertical, perpendicular, horizontal", and "top, bottom" is usually based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description.

[0036] In addition, it should be noted that the use of terms such as "first" and "second" to define components is only for the convenience of differentiating the corresponding components. Without additional statements, the above terms have no special meanings, and thus should not be construed as limiting the protection scope of the present invention.

[0037] As Figures 1-8 shown, this embodiment provides a channel selector, which includes a moving carrier 1 and a conductive module 2. The moving carrier 1 is slidably assembled, and the conductive module 2 is slidably assembled within the moving carrier 1. A conductive member 22 is provided on the conductive module 2. The conductive module 2 can be extended from the moving carrier 1 under the drive of a linear module 3, and the conductive member 22 can be expanded outward under the drive of the linear module 3 to connect to an external channel 7.

[0038] The moving carrier 1 is in the shape of a square frame, and sliders 11 extend from opposite sides of the moving carrier 1 to facilitate slidable assembly. An opening is formed on the moving carrier 1, and the conductive module 2 extends from the opening of the moving carrier 1 under the drive of the linear module 3. Preferably, the sliding direction of the conductive module 2 within the moving carrier 1 is perpendicular to the sliding direction of the moving carrier 1.

[0039] The first end of the conductive module 2 is slidably assembled within the mobile carrier 1, and the second end of the conductive module 2 extends out from the opening of the mobile carrier 1. A conductive member 22 is disposed at the second end of the conductive module 2. Specifically, the first end of the conductive module 2 extends into the mobile carrier 1 from the opening and is slidable along the mobile carrier 1. To prevent the conductive module 2 from disengaging from the mobile carrier 1, a limiting protrusion 21 is formed at the end of the first end of the conductive module 2. The limiting protrusion 21 can extend into the mobile carrier 1 and slidably cooperate with the inner wall of the mobile carrier 1. The limiting protrusion 21 can slide to abut against the opening of the mobile carrier 1 to prevent the conductive module 2 from detaching from the mobile carrier 1. Two conductive members 22 are assembled at the second end of the conductive module 2. Two connecting portions 221 are provided on each conductive member 22. A groove adapted to the shape of the conductive member 22 is formed on the outer surface of the second end of the conductive module 2. Through the arrangement of the groove, in the initial state, the conductive member 22 is embedded in the groove under the action of the linear module 3. In the connected state, the conductive member 22 can be driven by the linear module 3 to expand outwards and disengage from the groove, and will not move linearly with the linear module 3. The connecting portion 221 on the conductive member 22 can contact the external channel 7 to form an electrical connection.

[0040] As a preferred technical solution of this embodiment, the conductive module 2 is of a hollow structure. Its first end is cylindrical, and the second end is a square tube. The conductive body 22 is in a bent sheet shape. Each conductive body 22 has two mutually perpendicular outer surfaces, and the two mutually perpendicular outer surfaces are axially offset. The two connecting portions 221 are respectively located on the two outer surfaces. Preferably, the connecting portion 221 can be set as a finger structure (not shown in the figure). The finger structure includes a contact portion for lapping with the external channel 7. The finger structure may further include a buffer portion. The buffer portion is disposed on one side of the contact portion, and a part of the buffer portion protrudes from the contact portion. When the contact portion laps with the external channel, the protruding portion of the buffer portion contacts the external channel prior to the contact portion to play a buffering role. The buffer portion is made of nylon plastic. Nylon has high mechanical strength, wear resistance and good toughness, and is not easily broken when bent. When lapping, the buffer portion contacts the external channel 7 first to buffer part of the pressure, so that the contact portion and the external channel 7 lap slowly, avoiding damage to the surface plating of the external channel 7 caused by excessive friction during direct contact, thereby reducing the copper bar current-carrying capacity of the external channel 7 and resulting in circuit failures or even burning out of the external channel 7.

[0041] The conductive module 2 slides along the moving carrier 1 driven by the linear module 3. The linear module 3 is assembled on the moving carrier 1, and the telescopic part of the linear module 3 drives the conductive module 2 to move relative to the moving carrier 1. The telescopic part of the linear module 3 first drives the conductive module 2 to slide along the moving carrier 1. When the limit protrusion 21 on the conductive module 2 abuts against the opening of the moving carrier 1 and is limited, the linear module 3 then drives the two conductive parts 22 to expand outwards to connect to the external channel 7. Specifically, the telescopic part of the linear module 3 acts on the conductive module 2 through the elastic part 4, and the telescopic part of the linear module 3 is also connected to the conductive part 22; the linear module 3 first elastically pushes the conductive module 2 to slide along the moving carrier 1, and the second end of the conductive module 2 extends out of the opening of the moving carrier 1. When the conductive module 2 is limited by the moving carrier 1, the telescopic part of the linear module 3 continues to extend, the elastic part 4 is compressed, and the telescopic part of the linear module 3 pushes the conductive part 22 to expand outwards.

[0042] In this embodiment, the linear module 3 includes a driving part 31, a screw rod 32 and a screw sleeve 33. The driving part 31 is assembled on the moving carrier 1, the screw rod 32 is rotatably assembled on the moving carrier 1, the screw rod 32 and the screw sleeve 33 are in threaded cooperation, and the screw sleeve 33 extends into the inside of the conductive module 2 to drive the conductive module 2 to work. Specifically, one end of the screw sleeve 33 close to the driving part 31 extends with a limiting part 331. The elastic part 4 is sleeved on the screw sleeve 33, and both ends of the elastic part 4 act on the limiting part 331 and the limit protrusion 21 respectively; the other end of the screw sleeve 33 extends into the second end of the conductive module 2 and is connected to the conductive part 22 to drive the conductive part 22 to expand outwards. Among them, the elastic part 4 can be, but is not limited to, a spring.

[0043] The screw sleeve 33 is connected to the conductive part 22 through a connecting rod assembly 5. The connecting rod assembly 5 includes a first connecting rod 51, a second connecting rod 52 and a third connecting rod 53. One end of the first connecting rod 51 is hinged to the end of the screw sleeve 33, the other end of the first connecting rod 51 is hinged to one end of the second connecting rod 52, the other end of the second connecting rod 52 is fixedly connected to the middle of the third connecting rod 53, and both ends of the third connecting rod 53 are fixedly connected to the same conductive part 22. Preferably, the third connecting rod 53 is arranged parallel to the axis, and the bent part of the third connecting rod 53 close to the conductive part 22; the number of the connecting rod assemblies 5 corresponds to the number of the conductive parts 22.

[0044] In the channel selector of this embodiment, in the non-use state or the sliding state, the conductive module 2 can be accommodated in the moving carrier 1 driven by the linear module 3 to reduce the volume and facilitate sliding.

[0045] This embodiment also provides a power divider, which includes the above-mentioned channel selector, and further includes a guide rail 6 and an external channel 7. The channel selector slides along the guide rail 6. There are two opposite chutes opened on the guide rail 6. The slider 11 on the moving carrier 1 extends into the chute to prevent the moving carrier 1 from disengaging from the guide rail 6. The channel selector slides along the guide rail 6 driven by a driving component. The driving component is arranged on the guide rail 6. The driving component includes a pulley 61 and a belt 62. There are two pulleys 61, and the two pulleys 61 are respectively rotatably arranged at both ends of the guide rail 6. The belt 62 is sleeved on the two pulleys 61. The moving carrier 1 of the channel selector is connected to the belt 62. When the driving device drives the pulley 61 to rotate, the belt 62 on the pulley 61 can drive the channel selector to slide along the guide rail 6. Preferably, the extending direction of the guide rail 6 is perpendicular to the sliding direction of the conductive component 2 along the moving carrier 1.

[0046] The external channels 7 are arranged in an array. The external channel 7 includes a first channel 71 and a second channel 72. There is at least one group of the first channels 71, and at least two groups of the second channels 72. The first channels 71 are parallel to each other, and the second channels 72 are parallel to each other. The first channels 71 and the second channels 72 are vertically staggered. Each group of the first channels 71 includes two parallel first copper bars, specifically a first positive copper bar 711 and a first negative copper bar 712. Each group of the second channels 72 includes two parallel second copper bars, specifically a second positive copper bar 721 and a second negative copper bar 722. The first channels 71 can be arranged on one side or both sides of the second channels 72. The two first copper bars of the same group of the first channels 71 are located on the same side of the second channels 72. Adjacent groups of the first channels 71 are separated by insulators 73, and adjacent groups of the second channels 72 are separated by insulators 73. Preferably, the first channels 71 are input channels, and the second channels 72 are output channels. In this embodiment, there are multiple groups of the first channels 71, which are respectively arranged in an array on both sides of the second channels 72.

[0047] The guide rail 6 is arranged parallel to the first channels 71, and the number of the guide rails 6 is the same as and correspondingly arranged with the number of the first channels 71. The guide rail 6 is located between the two first copper bars of the corresponding first channels 71. When the channel selector slides along the guide rail 6, the conductive module 2 is located between the two first copper bars of the first channels 71. After the channel selector slides to the working position, it can extend between the two second copper bars of the second channels 72. The conductive body 22 then expands outwards to connect the first channels 71 and the second channels 72. One conductive body 22 connects the first positive copper bar 711 and the second positive copper bar 721, and the other conductive body 22 connects the first negative copper bar 712 and the second negative copper bar 722.

[0048] Preferably, a gun wire output electrical protection 8 is provided at the bottom of the external channel 7, and the gun wire output electrical protection 8 at the bottom can provide secondary protection for the conducted line; the power distributor further includes a housing 9, and the housing 9 covers the outside of the external channel 7, the channel selector and the guide rail 6 to play a role in dust protection.

[0049] Based on the above structure, the power selector of this embodiment can realize the selection and distribution of power by moving the channel selector along the guide rail to different working positions to connect the external first channel and second channel; the channel selector has a telescopic and expanding structure. When moving to the working position, the conductive module can be at least partially contracted in the moving carrier and slide with the moving carrier, which can effectively avoid interference with the external channel; when moving to the working position, the conductive module can extend out of the moving carrier, and the conductive parts expand outwards to connect the external channel. Compared with the relay, the channel selector of this application does not require fixed wiring, has good flexibility and strong applicability.

[0050] The above has described in detail the embodiments of the present invention with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the scope of knowledge possessed by those of ordinary skill in the art.
