Description

Technical Field

[0001] The present application belongs to the technical field of new energy vehicle design and manufacturing, and in particular, relates to a connector structure and an electric vehicle. Background Art

[0002] In new energy electric vehicles, batteries provide power to drive motors and other electrical loads. Generally, the connection between the battery and the drive motor and other electrical loads is made through a connector structure. The connection through the connector structure allows the battery, drive motor or other electrical loads to be installed flexibly without the need to follow a fixed installation sequence. On the other hand, the battery, drive motor or other electrical loads can be disassembled separately for easy maintenance and replacement.

[0003] In the related art, the connector structure includes a dedicated fixed shell, which is fixedly mounted on the frame of the electric vehicle so that the relative position of the entire connector structure relative to the frame is fixed. When plugging the plug of the drive motor or other electrical load into the plug-in interface of the connector structure, since the relative position of the entire connector structure relative to the frame is fixed, the staff must constantly adjust the plug-in angle of the plug until the plug is fully aligned with the plug-in interface of the connector structure to complete the plug-in operation, which greatly affects the work efficiency of completing the plug-in operation. Moreover, since the connector structure uses a dedicated fixed shell, the overall volume of the connector structure is relatively large, resulting in a larger installation position on the frame being occupied. Summary of the invention

[0004] The purpose of the present application is to provide a connector structure and an electric vehicle, aiming to solve the problem in the related art that the connector structure between the battery of the electric vehicle and the power load is large in size and has low efficiency in completing the plug-in operation.

[0005] To achieve the above purpose, the technical solution adopted in this application is: a connector structure, comprising:

[0006] A mounting base, used for mounting on a fixed mounting surface, wherein the mounting base forms an assembly space;

[0007] The socket has a plugging interface for plugging with the plug in a matching manner. The plugging interface is arranged at one end of the socket away from the fixed installation surface. The socket is movably installed in the assembly space.

[0008] The connector structure provided by the embodiment of the present application is used to transfer between the battery and the drive motor, and between the battery and the power load on the electric vehicle.

In addition, in the connector structure, the socket is installed on the fixed mounting surface of the frame of the electric vehicle through the mounting base.

[0011] In some embodiments of the present application, each mounting member further includes a stopper, the stopper is fixedly sleeved on the threaded member, the first elastic member is sleeved on the threaded member, and the two ends of the first elastic member respectively abut against the stopper and the mounting base. The stopper defines the spacing between the fixed mounting surface and the mounting base or between the fixed mounting surface and an end of the socket facing the fixed mounting surface, ensuring that the mounting base or the socket will not have a rigid contact with the fixed mounting surface, thereby protecting the connector structure.

[0012] In some embodiments of the present application, the mounting base includes a first substrate and a second substrate, the first substrate and the second substrate are stacked to form an assembly space, the first substrate is provided with a first opening, and the plug interface is arranged opposite to the first opening.

[0013] In some embodiments of the present application, one end of the socket having the plug-in interface extends through the first opening, which is beneficial for the staff to first observe the plug-in interface to understand the position of the plug-in interface, thereby completing the plug-in operation quickly and accurately, thereby improving the work efficiency of the plug-in operation.

[0014] In some embodiments of the present application, the second substrate is provided with a second opening opposite to the first opening, and the end of the socket facing the fixed mounting surface passes through the second opening.

The corresponding protrusions are limited and guided by the respective guide spaces, thereby greatly improving the working efficiency of the plugging operation of plugging the plug into the plug interface.

[0016] In some embodiments of the present application, the connector structure further includes a plurality of second elastic members, the first end of each second elastic member is connected to the socket, the second end of each second elastic member is connected to the mounting base, and the plurality of second elastic members provide elastic force to the socket so that the socket can move along a plane parallel to the fixed mounting surface under the limit cooperation of the protrusion and the assembly space. The plurality of second elastic members cooperate together to act on the socket so that the plug and the socket are fully aligned, and then the plug is plugged into the plug interface to achieve the transfer, which greatly improves the working efficiency of the plug-in operation of plugging the plug into the plug interface, and can make each protrusion of the socket restore to a balanced state before being subjected to the component force parallel to the fixed mounting surface relative to the mounting base in the guide space, and the socket can move along a plane parallel to the fixed mounting surface under the limit cooperation of the protrusion and the assembly space.

During the process of guiding and cooperating between the second guide structure and the first guide structure for relative movement, the socket performs adaptive movement and position adjustment, so that the plug interface of the socket is fully aligned with the plug, so that the plug can be quickly and accurately plugged into the plug interface.

[0018] In some embodiments of the present application, the first guide structure is a guide socket, and the inner edge area of ​​the opening of the guide socket is provided with a guide slope. The end of the guide column can be quickly and accurately guided and inserted into the guide socket under the guiding action of the guide slope, thereby driving the socket to adaptively move and adjust its position in a plane parallel to the fixed installation surface, so that the plug interface of the socket is fully aligned with the plug, so that the plug can be quickly and accurately plugged into the plug interface.

[0044] As people's quality of life continues to improve, the frequency of people using cars for transportation has gradually increased, thus driving the continuous development of the automobile industry. The growth and development of new energy electric vehicles in recent years has been particularly significant, involving family cars for transportation, short-distance passenger buses, long-distance passenger rail trains, short-distance freight trucks and other types of vehicles. Among them, the development momentum of new energy electric vehicles (hereinafter referred to as electric vehicles, electric vehicles in a narrow sense refer to family cars for transportation) is particularly rapid, and the market share of electric vehicles in the automobile market has increased year by year.

[0045] Electric vehicles use drive motors to output power, and drive motors require batteries to provide the required electrical energy. In addition, batteries also power the electrical loads on electric vehicles. The battery, drive motor, and other electrical loads are connected via a connector structure. The connection via the connector structure allows the battery, drive motor, or other electrical loads to be installed flexibly without the need to follow a fixed installation order. On the other hand, the battery, drive motor, or other electrical loads can be disassembled separately for easy maintenance and replacement.

[0046] In the related art, the connector structure includes a dedicated fixed shell, which is fixedly mounted on the frame of the electric vehicle so that the relative position of the entire connector structure relative to the frame is fixed. When plugging the plug of the drive motor or other electrical load into the plug-in interface of the connector structure, since the relative position of the entire connector structure relative to the frame is fixed, the staff must constantly adjust the plug-in angle of the plug until the plug is fully aligned with the plug-in interface of the connector structure to complete the plug-in operation, which greatly affects the work efficiency of completing the plug-in operation. Moreover, since the connector structure uses a dedicated fixed shell, the overall volume of the connector structure is relatively large, resulting in a larger installation position on the frame being occupied.

[0047] Based on the above considerations, the embodiment of the present application is designed to provide a connector structure, through which the battery and the drive motor, and the battery and the power load are transferred to achieve normal power supply. Compared with the existing connector structure in the related art, the connector structure cancels the dedicated fixed shell, and is directly installed on the fixed mounting surface of the frame of the electric vehicle through the mounting base, so that the overall volume of the connector structure is reduced, and the installation position required to be occupied by the connector structure on the frame of the electric vehicle is reduced, thereby optimizing the use of the limited space of the electric vehicle. In addition, the socket of the connector structure is movably installed in the assembly space of the mounting base. When the socket is used to plug in with a matching plug, the socket can move relative to the mounting base in the assembly space in a plane parallel to the fixed mounting surface, that is, the socket can be adaptively moved relative to the plug to adjust the position, so that the socket and the plug after the adaptive movement are fully aligned, and the plug is successfully plugged into the plug interface of the socket. In this way, during the process of plugging the plug into the socket, compared with the existing connector structure in the related art, which requires continuous adjustment of the plugging angle of the plug in order to fully align the plug with the plugging interface of the socket, the connector socket provided in the embodiment of the present application is adapted to the plug by adaptively moving and adjusting the socket in the assembly space, without the need to continuously adjust the plugging angle of the plug, thereby greatly improving the work efficiency of completing the plugging operation between the plug and the socket.

[0048] The fixed installation surface is generally considered to be a plane, and in the embodiment of the present application, it refers to a flat surface within a certain area on the crossbeam / longitudinal beam of the frame.

[0049] like Figures 1 to 5 As shown, the connector structure 100 provided by the embodiment of the present application includes a mounting base 10 and a socket 20, and the mounting base 10 provides the socket 20 with the required mounting position and support. The mounting base 10 is used to be mounted on a fixed mounting surface 211, and the mounting base 10 forms an assembly space. The socket 20 has a plug-in interface 21 for plugging in with the plug 50 in a matching manner, and the plug-in interface 21 is arranged at one end of the socket 20 away from the fixed mounting surface 211. The socket 20 is movably mounted in the assembly space, that is, the socket 20 can move relative to the mounting base 10 along a plane parallel to the fixed mounting surface 211 in the assembly space, and the socket 20 is adaptively moved and adjusted in the assembly space to adapt to the plug 50, so that the plug 50 can be quickly and accurately plugged into the plug-in interface 21 of the socket 20, thereby improving the working efficiency of the plug-in operation.

[0050] The connector structure 100 provided by the embodiment of the present application is used to transfer between the battery 220 and the drive motor 230, and between the battery 220 and the power load on the electric vehicle 200. Since the socket 20 of the connector structure 100 is movably installed in the assembly space of the mounting base 10, during the process of plugging the plug 50 into the plug interface 21 of the socket 20, the socket 20 can be adaptively moved and adjusted in the assembly space, so that the plug interface 21 of the socket 20 is adaptively aligned with the plug 50, so that the plug 50 can be quickly and accurately plugged into the plug interface 21, thereby realizing the transfer, which greatly improves the working efficiency of the plugging operation of plugging the plug 50 into the plug interface 21. Furthermore, in the connector structure 100, the socket 20 is mounted on the fixed mounting surface 211 of the frame 210 of the electric vehicle 200 through the mounting base 10. Compared with the existing connector structure in the related art, the connector structure 100 eliminates the dedicated fixed shell, thereby reducing the overall volume of the connector structure 100. The installation position required to be occupied by the connector structure 100 on the frame 210 of the electric vehicle 200 is reduced, thereby optimizing the use of the limited space of the electric vehicle 200.

[0051] like Figures 1 to 5As shown, in some embodiments of the present application, the connector structure 100 further includes a mounting member 30, and a plurality of mounting members 30 are used to assemble the mounting base 10 and the frame 210 of the electric vehicle 200, that is, the mounting base 10 is mounted on the fixed mounting surface 211 through the plurality of mounting members 30. After the mounting base 10 is connected to the fixed mounting surface 211 of the frame 210 of the electric vehicle 200 by the plurality of mounting members 30, the side of the mounting base 10 facing the fixed mounting surface 211 is spaced from the fixed mounting surface 211, and the mounting member 30 enables the mounting base 10 to float in a direction close to the fixed mounting surface 211 when receiving an external force toward the fixed mounting surface 211. Generally, when the plug 50 is plugged in relative to the socket 20, a plug-in method from bottom to top, a plug-in method from top to bottom, a plug-in method from left to right, or a plug-in method from right to left can be adopted. When the plug 50 is plugged into the plug interface 21 of the socket 20, the socket 20 will be subjected to the force component applied by the plug 50 toward the fixed installation surface 211. Since the pins (commonly known as Pins) on the plug 50 and / or the plug interface 21 are generally slender, the external force that the Pins can withstand is relatively small. When the plug 50 and the plug interface 21 of the socket 20 are not fully aligned, and if the force component applied by the plug 50 to the socket 20 toward the fixed installation surface 211 exceeds the upper limit of the external force that the Pins can withstand, the Pins will be squeezed and bent by the force component. In this way, even if the plug 50 is finally plugged into the plug interface 21, it is easy to have poor contact or complete failure of the electrical connection, resulting in invalid plugging between the plug 50 and the socket 20, which needs to be disassembled and reworked for re-plugging. To this end, the connector structure 100 uses a plurality of mounting components 30 to connect the mounting base 10 to the fixed mounting surface 211, and the mounting components 30 enable the mounting base 10 to float in a direction close to the fixed mounting surface 211 when subjected to an external force toward the fixed mounting surface 211. That is, when the socket 20 is subjected to a component force toward the fixed mounting surface 211 applied by the plug 50, the socket 20 will transfer the component force to the mounting base 10, and then the mounting base 10 floats toward the fixed mounting surface 211 along the mounting components 30, thereby balancing the component force. In this way, the Pin pins on the plug 50 and / or the plug interface 21 can be protected from being squeezed and bent by the interaction force between the plug 50 and the socket 20, and the Pin pins on the plug 50 and / or the plug interface 21 are effectively protected.Moreover, in the process of plugging the plug 50 into the plugging interface 21 of the socket 20, the socket 20 will also be subjected to a force component applied by the plug 50 that is parallel to the fixed mounting surface 211. Under the action of this force component, the socket 20 can adaptively move and adjust within the assembly space, so that the plugging interface 21 of the socket 20 can adaptively align with the plug 50, so that the plug 50 can be quickly and accurately plugged into the plugging interface 21.

[0052] In some embodiments of the present application, Figure 1 As shown, each mounting member 30 includes a threaded member 31 and a first elastic member 32, wherein the threaded member 31 is a bolt. The mounting base 10 is connected to the fixed mounting surface 211 of the frame 210 of the electric vehicle 200 through the threaded member 31, and the first elastic member 32 realizes the mounting state that the mounting base 10 floats relative to the fixed mounting surface 211 along the threaded member 31 (that is, the first elastic member 32 realizes the connector structure 100 to float relative to the fixed mounting surface 211 in the third direction Z, as shown in FIG. Figure 1As shown). Specifically, the mounting base 10 is provided with a through hole, and the threaded member 31 passes through the through hole and is screwed to the fixed mounting surface 211, and the first elastic member 32 is arranged between the mounting base 10 and the fixed mounting surface 211. In this way, after the threaded member 31 is screwed to the fixed mounting surface 211, the first elastic member 32 undergoes elastic deformation and has elastic potential energy, which makes the first elastic member 32 provide the mounting base 10 with an elastic force to move the mounting base 10 away from the fixed mounting surface 211. When the socket 20 is subjected to the component force applied by the plug 50 toward the fixed mounting surface 211, the socket 20 will transfer the component force to the mounting base 10, and then to the first elastic member 32 of the mounting member 30, so that the first elastic member 32 is further elastically deformed, and the mounting base 10 floats along the threaded member 31 of the mounting member 30 toward the fixed mounting surface 211, thereby balancing the component force. In this way, the Pin pins on the plug 50 and / or the plug interface 21 can be protected from being squeezed and bent by the interaction force between the plug 50 and the socket 20, and the Pin pins on the plug 50 and / or the plug interface 21 are effectively protected. When the plug 50 needs to be pulled out from the plug interface 21, due to the friction between the Pin pins and the socket between the plug 50 and the plug interface 21, the plug 50 will drive the socket 20 to move away from the fixed installation surface 211, so that the interaction force is generated between the socket 20 and the installation base 10. In addition, the installation base 10 transmits the interaction force applied by the socket 20 to the stopper head of the screw member 31 (for example, the end of the bolt for the matching wrench), and the installation base 10 is limited by the stopper head, and the screw member 31 is stably screwed on the fixed installation surface 211, so that the connector structure 100 is always stably connected to the fixed installation surface 211. Then, the plug 50 is separated from the plug interface 21 under the unplugging operation of the staff.

[0053] In some embodiments of the present application, Figure 1As shown, each mounting member 30 further includes a stopper 33, and the stopper 33 is used to stop the first elastic member 32. Specifically, the stopper 33 is fixedly sleeved on the threaded member 31, and the first elastic member 32 can be, but is not limited to, a coil spring, which is sleeved on the threaded member 31, and the two ends of the coil spring respectively abut against the stopper 33 and the mounting base 10, that is, the first elastic member 32 is sleeved on the threaded member 31 in a pre-tightened and compressed manner. When each mounting member 30 is assembled on the mounting base 10, the threaded member 31 is first passed through each through hole of the mounting base 10, and then the coil spring is sleeved on the mounting base 10 (at this time, the coil spring is located on the side of the mounting base 10 away from the stopper head of the threaded member 31), and then the stopper 33 is sleeved on the threaded member 31, and the coil spring is pre-tightened and compressed, and then the stopper 33 and the threaded member 31 are fixed. In this way, when the connector structure 100 is installed on the fixed installation surface 211 of the frame 210 of the electric vehicle 200, it is only necessary to screw each threaded member 31 into each threaded hole on the fixed installation surface 211 to complete the installation, and the installation work efficiency is high. In addition, since the limiter 33 is fixed on the threaded member 31, the interval between the fixed installation surface 211 and the installation base 10 or between the fixed installation surface 211 and the end of the socket 20 facing the fixed installation surface 211 is limited, ensuring that the installation base 10 or the socket 20 will not have a rigid contact with the fixed installation surface 211, thereby protecting the connector structure 100. When the socket 20 is subjected to a force component applied by the plug 50 toward the fixed mounting surface 211, the coil spring is further compressed, and the mounting base 10 floats along the threaded member 31 of the mounting component 30 toward the fixed mounting surface 211, thereby balancing the force component and effectively protecting the plug 50 and / or the Pin pins on the plug interface 21 from being squeezed and bent by the interaction force between the plug 50 and the socket 20.

[0054] In other embodiments of the present application, the first elastic member 32 can also be selected from components that can be elastically deformed, such as spring clips, elastic compression airbag springs, silicone sleeves, etc., and the elastic deformation of these components can be used to balance the component of force exerted by the plug 50 on the socket 20 toward the fixed mounting surface 211, thereby protecting the plug 50 and / or the Pin pins on the plug interface 21.

[0055] like Figures 1 to 3As shown, in some embodiments of the present application, the mounting base 10 includes a first substrate 11 and a second substrate 12, which are stacked to form an assembly space, and the socket 20 is movably mounted in the assembly space. The first substrate 11 is provided with a first opening 111, and the plug interface 21 is arranged opposite to the first opening 111, so as to facilitate the plug 50 to be plugged into the plug interface 21 of the socket 20. When the first substrate 11, the socket 20 and the second substrate 12 are assembled: the socket 20 can be placed on the first substrate 11 first, and then the second substrate 12 is covered on the first substrate 11, and then the rivets are inserted into each through hole and the first substrate 11 and the second substrate 12 are riveted and fixed (the assembly structure between the first substrate 11, the second substrate 12 and the rivet is also called a three-rivet structure), so as to limit the activity of the socket 20 in the assembly space formed by the first substrate 11 and the second substrate 12. In addition, a through hole is provided in the middle of the rivet coaxially with the through hole, and the screw member 31 passes through the through hole. By stacking the first substrate 11 , the socket 20 and the second substrate 12 in sequence, the three can be assembled smoothly and simply, thereby improving assembly efficiency.

[0056] like Figure 2 and Figure 4 As shown, in some embodiments of the present application, one end of the socket 20 provided with the plug interface 21 passes through the first opening 111. In this way, the plug interface 21 of the socket 20 can be clearly observed, and when the plug 50 is plugged into the plug interface 21, it is helpful for the staff to first observe the plug interface 21 to understand the position of the plug interface 21, and then move the plug 50 to a rough position relative to the plug interface 21 for plugging, and the socket 20 is adaptively moved and adjusted in the plugging process, so that the plug 50 is completely aligned with the plug interface 21, so that the plugging operation is completed quickly and accurately, and the working efficiency of the plugging operation is improved.

[0057] In other embodiments of the present application, one end of the socket 20 provided with the plug interface 21 is sunk into the first opening 111, that is, the plug interface 21 is completely located in the assembly space. In this way, when the plug 50 is plugged into the plug interface 21, the plug 50 needs to pass through the first opening 111 and then be plugged into the plug interface 21. When the staff plugs the plug 50 into the plug interface 21, they can predict through the first opening 111 to move the plug 50 to a rough position, and then insert it along the first opening 111, so that it can basically correspond to the plug interface 21. Then, in the process of plugging the plug 50 into the plug interface 21, the socket 20 will move and adjust the position adaptively, so that the plug 50 is fully aligned with the plug interface 21, thereby completing the plug operation quickly and accurately, and improving the working efficiency of the plug operation.

[0058] like Figure 3As shown, in some embodiments of the present application, the second substrate 12 is provided with a second opening 121 opposite to the first opening 111, and one end of the socket 20 facing the fixed mounting surface 211 passes through the second opening 121. In this way, it is possible to avoid interference in the laying path of the cable due to the influence of the mounting base 10, so that the cable connecting the socket 20 and the battery 220 can be laid smoothly.

[0059] In other embodiments of the present application, one end of the socket 20 facing the fixed installation surface 211 is sunk into the second opening 121, that is, the cable wire drawn from the socket 20 for electrical connection to the battery 220 needs to pass through the second opening 121 and then be laid, thereby completing the electrical connection to the battery 220. In this way, the cable wire can be constrained by the second opening 121, so that the cable wire passes through the second opening 121 in an orderly manner, avoiding the situation where the cable wire is scattered and messy after being drawn from the socket 20.

[0060] like Figures 1 to 5As shown, in some embodiments of the present application, a plurality of guide spaces 14 are formed between the area surrounding the first opening 111 of the first substrate 11 and the area surrounding the second opening 121 of the second substrate 12. In addition, the socket 20 is provided with protrusions 22 corresponding to the plurality of guide spaces 14, and the protrusions 22 are integrally formed on the outer wall of the shell of the socket 20. In the connector structure 100, the protrusions 22 are inserted into the guide spaces 14, and both the first substrate 11 and the second substrate 12 are in contact with the protrusions 22. In this way, the socket 20 is restricted in the assembly space by the cooperation between the protrusions 22 and the guide spaces 14. Since the first substrate 11 and the second substrate 12 are both in contact with the protrusion 22, when the socket 20 is subjected to the force component applied by the plug 50 toward the fixed installation surface 211, the socket 20 immediately transmits the force component to the second substrate 12, that is, the socket 20 transmits the force component to the mounting base 10, and then the mounting base 10 transmits the force component to the coil spring, so that the coil spring is further elastically compressed and deformed, thereby balancing the force component. In addition, when the socket 20 is subjected to the force component applied by the plug 50 parallel to the fixed installation surface 211, the force component causes the protrusion 22 to move along the plane parallel to the fixed installation surface 211 in the guide space 14, that is, the socket 20 is adaptively moved and adjusted relative to the plug 50 under the action of the force component, so that the plug 50 and the socket 20 are completely aligned, and then the plug 50 is plugged into the plug interface 21, thereby realizing the transfer, which greatly improves the working efficiency of the plugging operation of plugging the plug 50 into the plug interface 21. When the plug 50 needs to be pulled out from the plug interface 21, due to the friction between the pin and the socket between the plug 50 and the plug interface 21, the plug 50 will drive the socket 20 to move away from the fixed installation surface 211, so that the socket 20 and the first substrate 11 generate an interaction force. In addition, the first substrate 11 transmits the interaction force applied by the socket 20 to the stopper head of the screw member 31, and the stopper head limits the first substrate 11, that is, limits the installation base 10, and the screw member 31 is stably screwed on the fixed installation surface 211, so as to keep the connector structure 100 always stably connected to the fixed installation surface 211. Then, the plug 50 is separated from the plug interface 21 under the unplugging operation of the staff.

[0061] like Figure 1 and Figure 2As shown, in some embodiments of the present application, the connector structure 100 further includes a plurality of second elastic members 40, the first end of each second elastic member 40 is connected to the socket 20, the second end of each second elastic member 40 is connected to the mounting base 10, and the plurality of second elastic members 40 provide elastic force to the socket 20 so that each protrusion 22 maintains a force balance state in the guide space 14. When the socket 20 is subjected to a force component parallel to the fixed mounting surface 211 applied by the plug 50, the plurality of second elastic members 40 cooperate together to balance the force component, and drive the protrusion 22 of the socket 20 to move along a plane parallel to the fixed mounting surface 211 in the guide space 14, that is, the socket 20 is adaptively moved and adjusted relative to the plug 50 under the action of the force component, so that the plug 50 and the socket 20 are fully aligned, and then the plug 50 is plugged into the plug interface 21, thereby realizing the transfer, which greatly improves the working efficiency of the plugging operation of plugging the plug 50 into the plug interface 21. After the plug 50 is completely plugged into the plug interface 21, the staff releases the plug 50, that is, the external force applied to the plug 50 by the staff is cancelled, and the component of force of the plug 50 acting on the socket 20 parallel to the fixed mounting surface 211 disappears. At this time, the multiple second elastic members 40 will work together on the socket 20 to make the various protrusions 22 of the socket 20 restore to the equilibrium state before being subjected to the component of force parallel to the fixed mounting surface 211 in the guide space 14 relative to the mounting base 10.

[0062] As shown Figure 1 , Figure 2 and Figure 4As shown, in some embodiments of the present application, a first guide structure 23 is provided at one end of the socket 20 away from the fixed installation surface 211, and the first guide structure 23 is used to be plugged in with the second guide structure 51 of the plug 50, so that the socket 20 overcomes the elastic force of the corresponding second elastic member 40 and moves along a plane parallel to the fixed installation surface 211. The movement displacement of the socket 20 in a plane parallel to the fixed installation surface 211 is decomposed into a first decomposed displacement along a first direction X and a second decomposed displacement along a second direction Y in the plane, and the first direction X and the second direction Y are perpendicular to each other in the plane. When the plug 50 is plugged into the plug interface 21, the second guide structure 51 on the plug 50 will first contact and cooperate with the first guide structure 23 on the socket 20. Then, in the process of guiding and cooperating between the second guide structure 51 and the first guide structure 23 for relative movement, the second guide structure 51 applies a force to the first guide structure 23, so that the socket 20 moves along a plane parallel to the fixed installation surface 211. That is, the second guide structure 51 applies a force to the first guide structure 23, which is decomposed into two mutually perpendicular component forces along the first direction X and the second direction Y, so that the socket 20 performs a first decomposed displacement along the first direction X and a second decomposed displacement along the second direction Y in the plane, respectively. The first decomposed displacement and the second decomposed displacement are combined into the movement of the socket 20 in the plane, that is, the socket 20 performs adaptive movement and position adjustment in the plane, so that the plug interface 21 of the socket 20 is fully aligned with the plug 50, so that the plug 50 can be quickly and accurately plugged into the plug interface 21.

[0063] In some embodiments of the present application, the first guide structure 23 can be configured as a guide socket, and, as Figure 1 and Figure 2 As shown, the inner edge area of ​​the opening of the guide jack is provided with a guide slope 24. Accordingly, the second guide structure 51 on the plug 50 can be set as a guide column, and as shown in FIG. Figure 4 As shown, the end of the guide column is set to a conical end or a spherical end. In the process of plugging the plug 50 into the plug interface 21, the end of the guide column can be quickly and accurately guided and inserted into the guide hole under the guiding action of the guide slope 24, and the guide column applies a force to the hole wall of the guide hole, thereby driving the socket 20 to adaptively move and adjust the position in a plane parallel to the fixed installation surface 211, so that the plug interface 21 of the socket 20 is fully aligned with the plug 50, so that the plug 50 can be quickly and accurately plugged into the plug interface 21.

[0064] In other embodiments of the present application, the first guide structure 23 can be set as a guide column, and correspondingly, the second guide structure 51 can be set as a guide socket. In this embodiment, when the plug 50 is plugged into the plug interface 21, the hole wall of the guide socket exerts a force on the guide column inserted into the guide socket, thereby driving the socket 20 to adaptively move and adjust the position in a plane parallel to the fixed installation surface 211, so that the plug interface 21 of the socket 20 is fully aligned with the plug 50, so that the plug 50 can be quickly and accurately plugged into the plug interface 21.

[0065] like Figure 1 As shown, in some embodiments of the present application, the end of the socket 20 away from the fixed installation surface 211 is provided with at least two guide sockets arranged in sequence along the second direction Y. In fact, two guide sockets arranged in parallel along the second direction Y are provided on the socket 20 of the connector structure 100, and correspondingly, two guide posts that match the two guide sockets are provided on the plug 50. When the staff moves the plug 50 to a rough position relative to the plug interface 21, the staff quickly adjusts the position of the plug 50 through the matching relationship between the two guide posts and the two guide sockets, so that the two guide posts are quickly adjusted to basically correspond to the two guide sockets, so that the two guide posts can be inserted into the two guide sockets. In this way, the work efficiency of plugging the plug 50 into the plug interface 21 can be effectively improved.

[0066] In some embodiments of the present application, Figure 2 As shown, relative to a plane passing through the hole axes of at least two guide plug holes, a plurality of second elastic members 40 are respectively arranged on both sides of the plane, and the plurality of second elastic members 40 are symmetrically arranged relative to the plane. Figure 2As shown, two second elastic members 40 are provided on each side of the plane, that is, a total of four second elastic members 40 are provided, and the four second elastic members 40 are tension springs. The preload elastic force applied by the four second elastic members 40 to the socket 20 is decomposed into a first component along the first direction X and a second component along the second direction Y. Among them: the first component forces of the two second elastic members 40 on the same side are equal in magnitude and opposite in direction, and thus cancel each other out; the second component forces of the four second elastic members 40 correspond to each other, are equal in magnitude and opposite in direction, and also cancel each other out. Therefore, the four second elastic members 40 act on the socket 20 together, so that each protrusion 22 of the socket 20 maintains a force balance state in the guide space 14. A plurality of second elastic members 40 cooperate with each other to act on the socket 20 so that the plug 50 is fully aligned with the socket 20, and then the plug 50 is plugged into the plug interface 21 to achieve the transfer. This greatly improves the working efficiency of the plugging operation of plugging the plug 50 into the plug interface 21, and enables the various protrusions 22 of the socket 20 to recover to a balanced state relative to the mounting base 10 in the guide space 14 before being subjected to a force component parallel to the fixed mounting surface 211.

[0067] According to another aspect of the present application, an electric vehicle 200 is designed and provided, such as Figure 6 The electric vehicle 200 includes a vehicle frame 210 and the aforementioned connector structure 100. The vehicle frame 210 is provided with a fixed installation surface 211, and the connector structure 100 is installed on the fixed installation surface 211.

[0068] The connector structure 100 provided by the embodiment of the present application is used to transfer between the battery 220 and the drive motor 230, and between the battery 220 and the power load on the electric vehicle 200. Since the socket 20 of the connector structure 100 is movably installed in the assembly space of the mounting base 10, during the process of plugging the plug 50 into the plug interface 21 of the socket 20, the socket 20 can be adaptively moved and adjusted in the assembly space, so that the plug interface 21 of the socket 20 is adaptively aligned with the plug 50, so that the plug 50 can be quickly and accurately plugged into the plug interface 21, thereby realizing the transfer, which greatly improves the working efficiency of the plugging operation of plugging the plug 50 into the plug interface 21. Furthermore, in the connector structure 100, the socket 20 is mounted on the fixed mounting surface 211 of the frame 210 of the electric vehicle 200 through the mounting base 10. Compared with the existing connector structure in the related art, the connector structure 100 eliminates the dedicated fixed shell, thereby reducing the overall volume of the connector structure 100. The installation position required to be occupied by the connector structure 100 on the frame 210 of the electric vehicle 200 is reduced, thereby optimizing the use of the limited space of the electric vehicle 200.

[0069] The connector structure 100 provided by the embodiment of the present application can be applied not only to the electric vehicle 200, but also to water navigation equipment, such as ships, submersibles, etc.; it can also be applied to flying navigation equipment, such as airplanes, gliders, spacecraft, etc.; or, it can also be applied to household appliances, such as refrigerators, air conditioners, electric water heaters, etc.
