Description

Background

In related art electric vehicles, a rigid conductive bus is capable of transmitting power from one connection point to another connection point, enabling charging and distribution of the electric vehicle. The rigid conductive bus comprises a solid conductor, an insulating layer coated on the outer part of the solid conductor, and a metal electromagnetic shielding layer assembled around the outer part of the insulating layer. Compared with a common stranded cable, the solid conductor of the rigid conductive bus has more than twice of the corresponding conductor cross-sectional area under the condition of the same volume, and the increase of the conductor cross-sectional area realizes higher power conductivity and heat capacity performance, and can be widely applied to static electric conduction loops of electric automobiles. By a manufacturing method of numerical control (english is called computer numerical control, abbreviated to CNC) bending, the rigid conductive bus bar can be bent into a desired shape according to the body profile of the vehicle body. However, if the shape of the rigid conductive bus is adjusted in the actual production and assembly process, on the one hand, the assembly is not very convenient, and on the other hand, the rigid conductive bus with the adjusted shape has connection stress at the connection position between the assembly and other electrical components, and after long-term use, the risk of causing electrical connection failure exists.

It will be apparent that embodiments of the utility model may be practiced without limitation to the specific details that are set forth by those skilled in the art.

It is to be understood that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the utility model, as the singular forms "a", "an" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.

It is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "inner", "outer" and the like are used herein for illustrative purposes only and are not limiting.

Hereinafter, specific embodiments of the present utility model will be described in more detail with reference to the accompanying drawings, which illustrate representative embodiments of the present utility model and not limit the present utility model.

In the related art, the rigid conductive bus has the advantages of low cost and good conductive performance, and is suitable for a static conductive loop with higher power of a new energy vehicle or a hybrid vehicle. However, the rigid conductive bus bar has high processing precision requirements due to the rigid structure, so that the rigid conductive bus bar cannot adapt to assembly tolerance, and has the problem of poor assembly performance such as connection stress. For example, in order to connect with the connection terminal by a fastener such as a screw, it is necessary to open a hole or to machine a hole-forming structure at the end of the rigid conductive bus bar. During wiring operation, the originally processed hole site is likely to be displaced from the connection hole of the terminal block. This requires the application of an external force to align the holes, resulting in a very inconvenient installation. Meanwhile, compared with a welding assembly mode, after the rigid conductive bus and the wiring terminal are assembled by adopting the fastener, the conductive contact area of the rigid conductive bus and the wiring terminal is smaller. Moreover, after prolonged use, loosening of the fasteners can also result in failure of electrical conduction between the rigid conductive bus bar and the terminal. If the conductive bus and the wiring terminal are assembled in a welding mode, the conductive bus is inconvenient to replace and repair, the wiring terminal is inevitably damaged in the repair process, the wiring terminal cannot be reused, and therefore the repair cost is increased.

To solve the drawbacks of the related art, the present utility model provides a conductive adaptor 120, a rigid conductive bus assembly, a charging stand assembly 100 and a vehicle, as shown in fig. 1 to 8. Wherein the rigid conductive bus assembly includes a conductive adaptor 120 and a rigid conductive bus 130. The ends of the inner conductors 131 of the rigid conductive bus 130 are welded together with the wire adapter. The conductive adaptor 120 is used as a flexible transitional connection structure between the rigid conductive bus 130 and circuit connectors such as a connection terminal of a charging interface, a connection terminal of a distribution box, a connection terminal of a power battery pack and the like, so as to adapt to the accumulated tolerance of the rigid conductive bus 130 during assembly, and simultaneously, the conductive adaptor is also beneficial to absorbing connection stress after the assembly is completed. The rigid conductive bus 130 here includes a conductor 131, an insulating layer 132, and a metal shield 133, which are sequentially arranged from the inside to the outside in the radial direction. The conductor 131 may be a solid hard conductor 131. The cross section of the conductor 131 may be circular, square, polygonal, etc. The cradle assembly 100 is mounted to a body of a vehicle, and the cradle assembly 100 is electrically connected to a power battery pack via a distribution box and is detachably connected to a charging gun of an external charging device when charging is required. The vehicle includes a power battery pack, a power distribution box, and a charging stand 110. The power cell pack, the distribution box and the charging stand 110 can be connected by a rigid conductive bus assembly.

The conductive adaptor 120, the rigid conductive bus assembly, the cradle assembly 100, and the vehicle provided according to the embodiments of the present utility model are described in detail below with reference to the examples of fig. 1 to 8, respectively.

A conductive adaptor 120 according to the first aspect of the present utility model is used to connect a rigid conductive bus 130 to an electrical terminal. The conductive adaptor 120 may include a first connection section 122, a bent section 123, and a second connection section 125 sequentially arranged in the length direction D1. The first connection section 122 is provided with a first connection hole 122a penetrating in the thickness direction D3. The first connection holes 122a are for connection to corresponding electrical terminals by fasteners 116 such as screws. The curved section 123 is configured to be capable of adaptively deforming when the first and second connection sections 122 and 125 are moved relative to each other. The second connection section 125 is for soldering to a conductor 131 of the rigid conductive bus 130. The second connection section 125 is not required to be provided with a hole, and is welded with the conductor 131 of the rigid conductive bus 130 by welding in the assembled state to the rigid conductive bus 130. This helps to increase the contact area of the second connection section 125 with the conductor 131 of the rigid conductive bus 130 and makes the connection structure therebetween more stable.

According to the conductive adaptor 120 of the first aspect of the present utility model, by providing the curved section 123 in the middle of the conductive adaptor 120, the first connection section 122 and the second connection section 125 are adaptively deformed when they move relative to each other. The tolerance accumulated during assembly of the rigid conductive bus 130 can be adapted, so that the rigid conductive bus 130 and the corresponding wiring terminal can be conveniently installed, and the stress at the connection part between the rigid conductive bus 130 and the corresponding wiring terminal can be effectively absorbed, so that the conductive connection is prevented from being invalid, and the long-term stable operation of the power transmission line is ensured.

For example, the conductive adaptor 120 may include n conductive metal sheets 121 stacked in the thickness direction D3. n is greater than or equal to 20, and n is a positive integer. The conductive metal sheet 121 is long or band-shaped. The thickness direction D3 is parallel to the thickness direction of the conductive metal sheet 121. The length direction of the conductive metal sheet 121 is parallel to the length direction D1 described above. The thickness of the conductive metal sheet 121 is smaller than the width of the conductive metal sheet 121. The width of the conductive metal sheet 121 is smaller than the length of the conductive metal sheet 121. As will be appreciated by those skilled in the art, the length direction D1, the width direction D2, and the thickness direction D3 of the conductive metal sheets 121 are perpendicular to each other. In the specific design, manufacture and application of the conductive adaptor 120, the cross-sectional area of the conductive adaptor 120 may be determined according to parameters such as current, voltage and power that need to be introduced, and accordingly, the thickness, width, length and number of the conductive metal sheets 121 may be further determined according to the cross-sectional area of the conductive adaptor 120. All the conductive metal sheets 121 corresponding to the first connection section 122 are welded to each other by any one of welding methods such as ultrasonic welding, electromagnetic pulse welding, laser welding, resistance welding, and the like. That is, portions of all the conductive metal sheets 121 corresponding to the first connection sections 122 are ultrasonically welded to each other. Here, after all the conductive metal sheets 121 are stacked, they may be collectively welded by ultrasonic welding. After soldering, the portions of all the conductive metal sheets 121 corresponding to the first connection sections 122 correspond to one rigid portion. The first connection hole 122a penetrates the entire conductive metal sheet 121 at a portion corresponding to the first connection section 122. Since the bending section 123 is not subjected to the welding process, the adjacent conductive metal sheets 121 can move independently of each other in the bending section 123, and the respective conductive metal sheets 121 can be adaptively moved toward each other or away from each other according to the stress state.

For example, the second connection section 125 includes a section to be welded 125a and a pre-welded section 125b arranged in order along the length direction D1. In the longitudinal direction D1, the to-be-welded segment 125a is closer to the curved segment 123 than the pre-welded segment 125b. That is, the pre-welded segment 125b is located at the end of the second connecting segment 125 remote from the curved segment 123. All the copper sheets corresponding to the pre-welded section 125b are welded to each other by any one of welding methods such as ultrasonic welding, electromagnetic pulse welding, laser welding, resistance welding, etc., to maintain the shape of the second connection section 125. It will be appreciated that the pre-welded segment 125b is typically welded when the conductive adapter 120 is made separately, thereby preventing the conductive metal sheet 121 of the second connecting segment 125 communicating with the curved segment 123 from unraveling, and further facilitating the localized welding of the second connecting segment 125 and the rigid conductive bus 130 to be assembled, and improving the welding efficiency. At the same time, it is also beneficial to ensure uniformity of the form and performance of each conductive adaptor 120 after being manufactured. The to-be-welded section 125a is not welded when the conductive adaptor 120 is manufactured independently, and is uniformly welded when the second connection section 125 needs to be assembled together with the rigid conductive bus 130, so that the welding cost is reduced and the production efficiency is improved.

In one example, the thickness of each conductive metal sheet ranges from 0.09mm to 0.15mm.

Alternatively, in the case where the thickness of the conductive metal sheet is 0.09mm to 0.15mm, the value of n may be in the range of 30 to 40.

It can be understood that, under the condition that the thickness of the conductive metal sheet is 0.09 mm-0.15 mm, the value range of n can be other positive integers except 30-40, so long as the technical purpose of the utility model can be realized through practical verification, and the corresponding technical problem can be solved.

In other examples, the thickness of each conductive metal sheet may be other than 0.09mm to 0.15 mm. Specifically, the cross-sectional area of the conductive adaptor 120 may be determined according to electrical parameters such as current, voltage, etc. that the conductive adaptor 120 is required to conduct, and considering the influence of temperature, conductive performance, etc. Accordingly, the thickness, length, and width of each conductive metal sheet may be further determined.

Further, the conductive metal sheet 121 is configured as a metal sheet made of any one of copper, nickel, aluminum, copper-nickel alloy, and copper-aluminum alloy. For example, the conductive metal sheet 121 is configured as one of a copper sheet, a copper-nickel alloy sheet, and a copper-aluminum alloy sheet.

The conductive metal sheet 121 of the present utility model is preferably a copper sheet.

A rigid conductive bus assembly provided according to the second aspect of the present utility model may include a rigid conductive bus 130 and the conductive adaptor 120 described above. Rigid conductive bus 130 may include conductors 131. The conductor 131 is preferably a solid conductor or a hollow conductor. The second connection section 125 of the conductive adaptor 120 is welded to the end of the conductor 131 by any one of welding methods such as ultrasonic welding, electromagnetic pulse welding, laser welding, resistance welding, and the like. And the two ends of the rigid conductive bus 130 along the length direction D1 are respectively connected with the conductive adapter 120. This allows both ends of the rigid conductive bus 130 to be transitional connected to corresponding electrical connections 113b, such as terminals, via the conductive transition 120.

According to the rigid conductive bus assembly of the second aspect of the present utility model, by applying the conductive adaptor 120 described above, the second connection section 125 of the conductive adaptor 120 is fixedly connected to the rigid conductive bus 130 by ultrasonic welding, so that the conductive adaptor 120 and the rigid conductive bus 130 are combined together for use, which is convenient for adaptively compensating for the assembly error between the rigid conductive bus 130 and the corresponding connection point, and is also convenient for installing the rigid conductive bus 130. The rigid conductive bus 130 and the conductive adaptor 120 form a combined conductor 131 through a welding process, so that a certain degree of flexible transition can be realized in a rigid conductive connection system of a new energy vehicle or a hybrid vehicle. The present utility model absorbs a certain amount of tolerance during assembly, enables looser manufacturing and relatively lower assembly accuracy in applications employing the rigid conductive connection system, and thus effectively reduces stress generated when the rigid conductive connection system is assembled to a vehicle body, as compared to a rigid conductive connection system that does not employ the conductive adapter 120. Therefore, in the case where the conductive adapter 120 is used for the rigid conductive bus 130 in the electric power connection system of the new energy vehicle or the hybrid vehicle, a solution for the weight reduction of the cable, the connection reliability, the assembly adaptation degree higher, and the assembly stress can be effectively reduced can be provided for the purpose of realizing the charging of a larger power. Applications in which a rigid conductive connection system is employed may include, but are not limited to, vehicles.

For example, the conductor 131 may be configured as a copper conductor or an aluminum conductor or other metallic conductor.

Alternatively, the conductor 131 may be configured as a solid copper conductor. The copper conductor has better electrical conductivity and heat capacity than other metal conductors 131 or alloy conductors 131. And the solid conductor has a larger cross-sectional area than the hollow conductor, which is advantageous in achieving higher power conductivity and heat capacity.

Alternatively, the end of the conductor 131 may be configured as a flat connection end 131a. The end of the conductor 131 is arranged to overlap the second connection section in the thickness direction D3 of the conductive via 120. In this way, the effective contact area between the end of the conductor 131 and the conductive adaptor 120 can be increased, so that the positioning is convenient during welding, and meanwhile, the stability and reliability of the connection structure of the conductor 131 and the conductive adaptor 120 after welding are improved.

According to the rigid conductive busbar assembly of the present utility model, the conductive adaptor 120 has rigid regions at both ends and flexible regions in the middle. The laminated copper sheets in the flexible area can keep independent movement, so that the laminated copper sheets have good flexibility. One end of the conductive adaptor 120 is connected with the conductor 131 of the rigid conductive bus 130 by welding, so as to form a combined flexible conductor capable of meeting excessive flexibility. The other end of the conductive adaptor 120 is connected to the electrical terminal 113 by a fastener 116. The electrical terminal mentioned here and in the following is also understood to be a connection terminal. The connection terminal has a fastener or a hole that can be connected to the first connection hole of the conductive adapter 120 by the fastener. The combined flexible conductor can effectively absorb accumulated tolerance of the rigid conductive bus 130 during assembly, and release rigid stress of the rigid conductive bus 130 caused by assembly.

The charging dock assembly 100 provided according to the third aspect of the present utility model may include a dock 111, an electrical terminal 113, a fastener 116, and a rigid conductive bus assembly as described above. The seat body is close to an outer surface of the vehicle in a mounted state to a body of the vehicle so as to be connected with a charging gun of an external charging device. The electrical terminal 113 is connected to the inside of the housing 111. The electrical terminal 113 has a plug portion 113a and a connection portion 113b that are oppositely arranged in the own longitudinal direction D1. The plug-in part 113a is used for plug-in matching with the conductive electrode of the charging gun. The connection portion 113b is provided with a second connection hole 113c. The first connection hole 122a of the conductive adaptor 120 is disposed corresponding to the second connection hole 113c in the thickness direction D3. The fastener 116 is sequentially penetrated through the first and second connection holes 122a and 113c to fasten the conductive adaptor 120 to the connection portion 113b of the electrical terminal 113.

According to the charging stand assembly 100 of the third aspect of the present utility model, by applying the rigid conductive bus bar assembly described above and fastening the rigid conductive bus bar assembly to the electrical terminal 113 by the fastener 116, the electrical terminal 113 and the rigid conductive bus bar 130 are connected, which is beneficial to solving assembly errors and absorbing stress at the connection position when the electrical terminal 113 and the rigid conductive bus bar 130 are directly connected.

In addition, the cradle assembly 100 may also include a protective soft cover 112. The protective soft cover 112 is connected to the base 111. The protective soft sleeve 112 is sleeved outside the conductive adaptor 120 and the connection of the conductive adaptor 120 with the electrical terminal 113 and the conductor 131 of the rigid conductive bus 130. The protective soft cover 112 is configured as a soft elastic structure to adaptively deform when the rigid conductive bus 130 moves relative to the electrical terminal 113. By providing the protective soft cover 112 and the base 111 together to form the housing structure of the charging base 110, the electric terminal 113, the conductive adapter 120 and part of the rigid conductive bus 130 can be wrapped and protected, and the purpose of insulation from the outside can be achieved. Further, since the protective soft cover 112 has a soft, elastic and insulating structure, it can be deformed adaptively according to the actual trend, assembly tolerance, etc. of the rigid conductive bus 130, and further assist the conductive adapter 120 to absorb the stress at the joint. The shell structure and characteristics of the charging stand 110 formed by the anti-slip soft sleeve and the stand body 111 can be in accordance with the specification and requirements of the national standard direct current charging stand 110.

Further, the protective soft cover 112 is sealingly mated to the base 111 and the rigid conductive bus 130. This helps to improve the insulating and waterproof properties of the cradle assembly 100.

For example, the protective soft cover 112 may be a structure made of rubber, silicone rubber, or the like having the same or similar properties.

In addition, the cradle assembly 100 may also include a signal harness assembly 115. The signal harness assembly 115 is partially located inside the installation space surrounded by the housing 111 and the protective soft cover 112, and is penetrated to the outside of the protective soft cover 112.

A vehicle provided according to a fourth aspect of the utility model may include a charging dock 110, a power box, a power cell, and at least two of the rigid conductive busbar assemblies described above. At least one of the at least two rigid conductive bus assemblies is electrically connected to the cradle 110 and the electrical box. At least another one of the at least two rigid conductive bus assemblies is electrically connected to the power cell and the distribution box.

The charging stand 110 may include the stand body 111, the electrical terminal 113, and the protection cover. The cradle assembly 100 is formed after the cradle 110 is connected to the rigid conductive bus assembly.

The electrical box herein may be configured to convert and transmit electrical energy from the charging dock 110 to the power battery to be adapted to charge the power battery.

According to the vehicle of the fourth aspect of the present utility model, by applying the above-described rigid conductive bus bar assembly to electrically connect the charging stand 110 and the distribution box between the charging stand 110 and the power battery and to electrically connect the distribution box and the power battery between the distribution box and the power battery, the tolerance accumulated in assembling the rigid conductive bus bar 130 can be absorbed by the conductive adapter 120, effectively reducing the stress of the rigid conductive bus bar 130 assembled to the vehicle.

In addition, the vehicle may further include an electric motor. The electrical box may be electrically connected to the motor by a rigid conductive bus bar assembly. The power distribution box may be configured to convert the electrical energy output by the power cells to power the motor.

The electrical box may also be electrically connected to the generator by a rigid conductive bus bar assembly. At this time, the distribution box may be configured to convert the electric energy generated by the generator to be suitable for charging the power battery.
