The embodiments of the present application are described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.

Referring to fig. 1 to 3, an embodiment of the present application provides an electrical connection assembly, which may be applied to the field of electric vehicles, and optionally, the electrical connection assembly may electrically connect a motor and an inverter to achieve power transmission between the motor and the inverter. Of course, the present invention can also be applied to other fields, which is not limited in this application, and the following description mainly takes the electrical connection between the motor and the inverter through the electrical connection assembly as an example to describe the specific structure of the electrical connection assembly.

In some embodiments, an electrical connection assembly is provided, which includes a first connection terminal 100, a second connection terminal 200, a first connector 300, a second connector 400, and an elastic member 500. The second connecting part 400 is connected to the second connecting terminal 200, and optionally, the second connecting part 400 may be fixedly connected or detachably connected to the second connecting terminal 200. For example, in some embodiments, the second connector 400 and the second connection terminal 200 may be fixedly connected by welding, riveting, or the like. In other embodiments, the second connector 400 and the second connection terminal 200 may be detachably connected by snapping, screwing, or the like.

Alternatively, the first connection terminal 100 and the second connection terminal 200 may be a copper bar or an aluminum bar, and may also be other conductive elements, which is not limited in this embodiment of the present application. For example, in some embodiments, the first connection terminal 100 and the second connection terminal 200 are each independently a copper bar.

Further, the second connector 400 is used to connect the first connector 300 and the second connection terminal 200, that is, the first connector 300 and the second connection terminal 200 may be connected by the second connector 400. The second connection member 400 has at least one section of flexible structure, that is, the second connection member 400 may have one, two or more sections of flexible structure, which means a structure capable of generating deformation. The flexible connection between the first connection terminal 100 and the second connection terminal 200 is facilitated by providing the second connection member 400 with at least one segment of a flexible structure.

The elastic member 500 is disposed between the first connecting member 300 and the second connecting terminal 200, and after the circuit is installed on the electrical connection component, that is, after the electrical connection component is installed on the electrical drive assembly, and the first connecting terminal 100 and the second connecting terminal 200 are connected to the motor and the inverter respectively, the elastic member 500 may be used to drive the first connecting member 300 to abut against the first connecting terminal 100.

Optionally, the second connector 400 has a cavity 410, at least a portion of the first connector 300 is disposed in the cavity 410, and at least a portion of the first connector 300 protrudes out of the cavity 410. In addition, in other embodiments, the second connection member 400 may not be enclosed into a cavity, which is not limited in this embodiment.

Optionally, the elastic element 500 may be disposed in the cavity 410 and connected between the first connecting element 300 and the second connecting terminal 200, and the elastic element 500 is used for driving the first connecting element 300 to abut against the first connecting terminal 100. It should be noted here that the cavity 410 may be a through cavity, one end of the through cavity faces the first connection terminal 100, the other end of the through cavity is connected to the second connection terminal 200, and the other end of the through cavity is sealed by the second connection terminal 200, so that the other end of the elastic member 500 may be limited by the second connection terminal 200.

Under the elastic force of the elastic member 500, the first connecting member 300 has a movement tendency toward the first connecting terminal 100, so that the first connecting member 300 can abut against the first connecting terminal 100 and generate pressure, thereby reducing contact resistance of contact surfaces of the first connecting member 300 and the first connecting terminal 100, realizing conduction current, and further realizing good conductivity between the first connecting member 300 and the first connecting terminal 100.

In some embodiments, both ends of the elastic member 500 may abut against the first connection terminal 300 and the second connection terminal 200, respectively; of course, both ends of the elastic member 500 may be fixedly connected to the first connection terminal 300 and the second connection terminal 200, respectively. Both of the above-mentioned two ways can apply the pressing force to the first connecting member 300 through the elastic member 500 to ensure that the first connecting member 300 is in good contact with the first connecting terminal 100.

The first connection terminal 100, the first connector 300, the second connector 400 and the second connection terminal 200 are electrically connected in sequence. Based on this, it is possible to cause current to flow along the first connection terminal 100, the first connection member 300, the second connection member 400, and the second connection terminal 200, thereby achieving the transmission of electric energy. It should be noted here that the first connection terminal 100, the first connection member 300, the second connection member 400, and the second connection terminal 200 may be all metal members capable of conducting electricity, and may also be a non-metal conductive member, as long as electrical connection can be achieved, and specific materials are not limited.

In the embodiment of the present application, the first connection terminal 100, the first connection member 300, the second connection member 400, and the second connection terminal 200 are electrically connected in sequence, so that electric energy transmission between two electrical components can be realized; moreover, the second connecting member 400 has at least one section of flexible structure, which can realize flexible connection; in addition, an elastic force may be applied to the first connector 300 by the elastic member 500. Therefore, on one hand, the first connecting piece 300 can be ensured to be tightly abutted against the first connecting terminal 100, and the first connecting piece 300 and the first connecting terminal 100 are electrically connected completely; on the other hand, the case of different distances between the first connection terminal 100 and the second connection terminal 200 can be adapted, so that the applicability of the electrical connection assembly can be improved, and at the same time, the flexible connection between the first connection member 300 and the second connection member 400 can be realized, so as to alleviate the problem of stress concentration formed between the two connection members due to tolerance factors.

Compared with the current mode of realizing electrical connection by adopting components such as an end head, a wiring harness, a screw, a nut and the like, the electric connection assembly in the embodiment of the application cancels screw connection, can simplify the dismounting process flow to a certain extent, and improves the dismounting efficiency; and the wiring harness is cancelled, so that the occupied space can be reduced to a certain extent, and the structure is more compact.

In the embodiment of the present application, the electrical connection assembly further includes a first guiding element 600, a first limiting structure 610 is disposed at one end of the first guiding element 600, the first connecting element 300 has a guiding channel 310, and a second limiting structure 320 is disposed in the guiding channel 310. When the connector is installed, one end of the first guide 600, which is away from the first limiting structure 610, passes through the guide channel 310 and is connected with the second connecting terminal 200, and the first limiting structure 610 is located in the guide channel 310 and can be in limiting fit with the second limiting structure 320. Alternatively, the first guide 600 may be a metal guide bar, and may also function as a conductive function.

Specifically, the first guide 600 passes through the guide passage 310, so that the portion of the first connecting element 300 located in the cavity 410 is located between the inner wall of the cavity 410 and the outer wall of the first guide 600, and is limited by the inner wall of the cavity 410 and the outer wall of the first guide 600, so that the first connecting element 300 moves along the first guide 600, on one hand, the stability of the first connecting element 300 can be ensured, and the first connecting element 300 is prevented from being twisted relative to the second connecting element 400 and the first connecting terminal 100, thereby affecting the contact integrity of the first connecting element 300 with the second connecting element 400 and the first connecting terminal 100, on the other hand, the moving accuracy of the first connecting element 300 can be improved, and accordingly, the contact integrity between the components can also be improved.

Because the first connecting member 300 is under the elastic force of the elastic member 500, the first connecting member 300 tends to move away from the second connecting member 400, and therefore, the first connecting member 300 can be effectively prevented from moving away from the second connecting member 400 by the limit cooperation of the first limit structure 610 and the second limit structure 320. When the first connector 300 moves to the most distal position, the second limiting structure 320 contacts the first limiting structure 610 and is limited by the first limiting structure 610, so that the first connector 300 can not move any more.

It should be noted here that, when the electrical connection assembly is in a normal use state, that is, after the electrical connection assembly is installed on a circuit, the first connection terminal 100 and the second connection terminal 200 are relatively fixed, the first connection member 300 will be subjected to the limiting action of the first connection terminal 100 and will not be separated from the second connection member 400, and meanwhile, the second limiting structure 320 and the first limiting structure 610 are spaced from each other, that is, through the limiting cooperation between the first limiting structure 610 and the second limiting structure 320, it can be ensured that the first connection member 300 can be abutted against the first connection terminal 100, and good contact between the two is ensured. Before the electrical connection assembly is mounted on the circuit, the first connecting element 300 is restrained by the first restraining structure 610 and the second restraining structure 320. When the electrical connection assembly is in a non-use state or needs to be disassembled, the first connection terminal 100 needs to be separated from the first connection member 300, and at this time, the first connection member 300 is limited by the first guide member 600 and cannot be separated from the second connection member 400.

In the embodiment of the present application, the electrical connection assembly further includes a second guiding member 700, the second guiding member 700 is connected to the first connection terminal 100, and the second guiding member 700 at least partially extends into the guiding channel 310. During the mounting process of the electrical connection assembly, the first connector 300 and the first connection terminal 100 may be provided with a mounting guide by the second guide 700 to ensure mounting accuracy.

In addition, after the electrical connection assembly is installed, the second guiding member 700 can limit the first connector 300 and the first connection terminal 100 from moving laterally, so that the stability of the contact between the first connector 300 and the first connection terminal 100 can be ensured.

In order to facilitate the penetration of the second guide 700 into the guide channel 310, an opening of one end of the guide channel 310 adjacent to the first connection terminal 100 is provided with a chamfer structure 330, i.e., a flare or an opening is formed, which increases a cross-sectional area of the opening of the guide channel 310, thereby facilitating the penetration of the second guide 700 into the guide channel 310.

In the embodiment of the present application, the first connection terminal 100 is provided with the first mounting hole 110, the second guide 700 is a guide pin, and one end of the guide pin is inserted into the first mounting hole 110, so that the second guide 700 is assembled with the first connection terminal 100. Of course, in other embodiments, one end of the second guiding member 700 may be directly fixed to the first connection terminal 100, for example, by welding, bonding, riveting, or the like, so as to fix the second guiding member 700 and the first connection terminal 100 relatively.

In order to facilitate the penetration of the second guide 700 into the guide passage 310, the other end of the guide pin is provided with a tip structure 710, so that the cross-sectional area of the end of the guide pin can be reduced to facilitate the penetration of the guide pin into the guide passage 310, thereby improving the installation efficiency of the electrical connection assembly.

In this embodiment, the elastic member 500 is a spring, the spring is sleeved on the outer side of the first guide 600, and at this time, the spring is located between the outer wall of the first guide 600 and the inner wall of the cavity 410, so that the spring can be limited by the outer wall of the first guide 600 and the inner wall of the cavity 410, and the spring is prevented from being bent and distorted when compressed, and thus the elastic force on the first connecting member 300 is prevented from being affected. Alternatively, the spring may be made of a metal material, which may also serve as a conductor.

In the implementation of the present application, the second connection terminal 200 is provided with the second mounting hole 210, and the end of the first guide 600 departing from the first limiting structure 610 is inserted into the second mounting hole 210 and is in threaded connection with the second mounting hole 210. Specifically, second mounting hole 210 is the screw hole, correspondingly, the one end that deviates from first limit structure 610 of first guide 600 is equipped with the external screw thread, when installation electrical connection component, pass guide channel 310 back with the one end of first guide 600, make the external screw thread of first guide 600 one end and the female connection of second mounting hole 210 to can make things convenient for the dismouting between first guide 600 and the second connecting terminal 200, and then can improve the holistic dismouting efficiency of electrical connection component.

In the embodiment of the present application, the second connection member 400 includes a flexible segment 421, and the flexible segment 420 is configured as a conductive member with a long strip-shaped structure or a linear strip-shaped structure.

Alternatively, the flexible segment 421 of the second connection element 400 can also be a conductive element with a linear strip structure, such as a flexible metal wire, e.g. a copper wire. Of course, in other embodiments, the flexible segment 421 of the second connection element 400 can also adopt other flexible conductive parts with various shapes, which is not limited in this embodiment.

In some embodiments, the second connector 400 includes a metal spring 420, the metal spring 420 has a flexible section 421, the metal spring 420 can enclose the cavity 410, and one end of the metal spring 420 is fixedly connected to the second connection terminal 200, and an inner wall of the other end is connected to an outer wall of the first connector 300. Alternatively, the metal dome 420 may be, for example, a stainless steel dome, a copper dome, an aluminum dome, or the like.

It should be noted that the metal elastic sheet 420 may be slightly deformed when being loaded, and may be restored to the original form after the load is removed, that is, the metal elastic sheet 420 may be elastically deformed. Based on this, when there is an assembly tolerance between the first connector 300 and the second connector 400, or the first connector 300 generates a small amount of lateral displacement relative to the second connector 400, the second connector 400 can be slightly deformed, so that the tolerance problem can be overcome by the slight deformation of the second connector 400, and an additional acting force (e.g., an acting force caused by the assembly tolerance or the low movement precision) applied to the first connector 300 can be reduced without causing the first connector 300 to be jammed, so that a flexible connection is formed between the first connector 300 and the second connector 400, and the adaptability of the electrical connection assembly can be improved.

In some embodiments, the metal dome 420 may include a plurality of dome units, the dome units are distributed in a central symmetry manner with respect to the axis of the cavity 410, and a gap exists between two adjacent dome units. When the connector is installed, a part of the first connector 300 is located in the cavity 410, and each spring sheet unit may be connected to a sidewall of the first connector 300, so that the electrical connection between the first connector 300 and the second connector 200 is realized through a plurality of spring sheet units, and the transmission of the electric energy is realized. Moreover, each spring plate unit can respectively generate elastic deformation when receiving acting force from the first connecting piece 300, so that flexible connection between the first connecting piece 300 and the second connecting piece 400 can be realized, and good assembly performance between the first connecting piece 300 and the second connecting piece 400 can be ensured.

In a specific embodiment, the first connector 300 may be a rectangular parallelepiped, and accordingly, the metal spring 420 may include four spring units, and the four spring units surround the cavity 410 with a square or rectangular cross section. During assembly, the four elastic sheets can be correspondingly abutted against the four side walls of the cuboid, so that the first connecting piece 300 can be abutted from four directions, and the electric connection is realized.

Further, the elastic sheet unit may be an elongated sheet structure, and at least a portion of the elongated sheet structure along its length direction is provided with an arc structure 4211, and a concave surface of the arc structure 4211 faces the inner side of the cavity 410. Optionally, the arc structure 4211 may be a semicircular bending structure, a plurality of semicircular bending structures, or a large arc structure, and the specific shape or number of the arc structures is not limited in this embodiment.
