[0082] The following describes the specific embodiments of the present disclosure in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure and are not intended to limit the present disclosure.

[0083] In the present disclosure, unless otherwise stated, the directional words used, such as "above", "below", etc., are generally defined in terms of the drawing direction of the corresponding drawings, and are only for the convenience of describing the present disclosure and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, and a specific orientation structure and operation, and therefore cannot be understood as a limitation on the present disclosure. "Inside" and "outside" refer to the inside and outside of the outline of the corresponding component. The use of terms such as "first" and "second" is intended to distinguish different components and does not have sequentiality and importance. Among them, the X direction shown in Figure 1 can be the first direction, the Y direction can be the second direction, and the Z direction can be the plug-in direction of the first connecting structure 2 and the second connecting structure 3. In addition, in the following description, when referring to the drawings, unless otherwise explained, the same figure marks in different drawings represent the same or similar elements.

[0084] It should also be noted that, in the description of this disclosure, unless otherwise expressly specified or limited, the terms "disposed," "connected," "connected," and "installed" should be understood broadly. For example, they may refer to fixed connections, detachable connections, or integral connections; and they may refer to direct connections or indirect connections via an intermediary. Those skilled in the art will understand the specific meanings of these terms in this disclosure based on specific circumstances.

[0085] As mentioned above, in the related art, during the process of aligning and plugging two connectors, the connectors are prone to wear. Research has found that the reason why the connectors are prone to friction is that due to the heavy weight of the modular components, it is inconvenient to move and align them. There may be a situation where the plug-in positions of the two connectors are not aligned, but the two connectors are directly docked. Thereafter, during the process of adjusting the plug-in position, the two connectors are in rigid contact, which can easily cause wear on the connectors. Moreover, during the plug-in process, the two connectors are directly connected hard along the plug-in direction of the two connectors, that is, a rigid connection is performed. The rigid contact and rigid friction under the rigid connection can easily cause wear on the connectors, thus shortening the service life of the connectors and reducing the reliability of the connector connection.

[0086] In view of this, as shown in Figures 1 to 9, the present disclosure provides a connection structure, including a first connection structure 2 and a second connection structure 3. The first connection structure 2 is suitable for being arranged on a module part 1 (such as the module part 1 located above the drawing in Figure 1), and the second connection structure 3 is suitable for being arranged on another module part 1 (such as the module part 1 located below the drawing in Figure 1), for plugging and matching with the first connection structure 2. The first connection structure 2 and the second connection structure 3 can cooperate with each other during the plugging process, so that the first connection structure 2 can move relative to the module part 1 provided with the first connection structure 2 and / or the second connection structure 3 can move relative to the module part 1 provided with the second connection structure 3, so that the first connection structure 2 and the second connection structure 3 can move relative to each other and guide the first connection structure 2 and / or the second connection structure 3 to a predetermined plug-in and matching position. Through the above technical solution, in the process of connecting two modules 1, the first connection structure 2 can move relative to the module 1 provided with the first connection structure 2, or the second connection structure 3 can move relative to the module 1 provided with the second connection structure 3, or the first connection structure 2 can move relative to the module 1 provided with the first connection structure 2, and the second connection structure 3 can move relative to the module 1 provided with the second connection structure 3, so that the first connection structure 2 and the second connection structure 3 can move relative to each other, thereby facilitating the guidance of the first connection structure 2 and the second connection structure 3 to the predetermined plug-in mating position, which can improve the convenience of connecting the first connection structure 2 and the second connection structure 3. At the same time, the step of subsequently adjusting the plug-in position of the first connection structure 2 and the second connection structure 3 can be omitted, thereby avoiding the wear of the first connection structure 2 and the second connection structure 3 caused by the subsequent adjustment of the plug-in position of the first connection structure 2 and the second connection structure 3.

[0087] Moreover, compared with the method of rigid plug-in of two connecting parts in the related art (the method in which the two connecting parts can neither rotate nor move), in the present disclosure, since the first connecting structure 2 and the second connecting structure 3 can move relatively during the plug-in process of the first connecting structure 2 and the second connecting structure 3, the impact force of the first connecting structure 2 and the second connecting structure 3 during the plug-in process can be buffered, thereby avoiding rigid contact and rigid friction between the first connecting structure 2 and the second connecting structure 3, which is conducive to achieving a flexible connection between the first connecting structure 2 and the second connecting structure 3, and can reduce the wear of the first connecting structure 2 and the second connecting structure 3, thereby helping to extend the service life of the first connecting structure 2 and the second connecting structure 3, and improve the reliability of the connection between the first connecting structure 2 and the second connecting structure 3.

[0088] It should be noted that a flexible connection refers to a connection method in which the connecting parts produce a certain amount of displacement by deformation or by forming an angle with the connection direction of the connecting parts, so as to cushion the impact force along the connection direction of the two connecting parts during the connection process. In the present disclosure, a flexible connection is a method in which the first connecting structure 2 and the second connecting structure 3 can cooperate with each other during the plug-in process, so that the first connecting structure 2 can move relative to the module 1 provided with the first connecting structure 2 and / or the second connecting structure 3 can move relative to the module 1 provided with the second connecting structure 3, so that the first connecting structure 2 and the second connecting structure 3 can move relative to each other.

[0089] It is understood that the first connection structure 2 being movable relative to the module 1 provided with the first connection structure 2 may refer to the first connection structure 2 being movable relative to the module 1 as a whole, or to some components of the first connection structure 2 being movable relative to the module 1. Similarly, the second connection structure 3 being movable relative to the module 1 provided with the second connection structure 3 may refer to the second connection structure 3 being movable relative to the module 1 as a whole, or to some components of the second connection structure 3 being movable relative to the module 1. This disclosure is not limited to this.

[0090] Furthermore, it is understood that, in the present disclosure, the module 1 can be a module 1 for mechanical connection or a module 1 for electrical connection. That is, the first connection structure 2 and the second connection structure 3 can be mechanically connected or electrically connected. The module 1 can be any component that can be connected using the connection structure provided in the present disclosure, including but not limited to a battery module.

[0091] In the present disclosure, any appropriate structure can be provided on the connection structure to realize the above-mentioned scheme that the first connection structure 2 and the second connection structure 3 can move relative to each other and guide the first connection structure 2 and / or the second connection structure 3 to a predetermined plug-in fitting position, and the present disclosure does not limit this. In some embodiments, as shown in Figures 1 and 2, the first connection structure 2 is provided with a first guide portion 4, and the second connection structure 3 is provided with a second guide portion 5. The first guide portion 4 is suitable for cooperating with the second guide portion 5 during the plug-in process of the first connection structure 2 and the second connection structure 3, so that the first connection structure 2 can move relative to the module 1 provided with the first connection structure 2 and / or the second connection structure 3 can move relative to the module 1 provided with the second connection structure 3, so that the first connection structure 2 and the second connection structure 3 can move relative to each other and guide the first connection structure 2 and / or the second connection structure 3 to a predetermined plug-in fitting position. With such an arrangement, during the process of plugging and fitting the two modular components 1, the first connecting structure 2 and the second connecting structure 3 can be relatively movable through the guiding cooperation of the first guide portion 4 and the second guide portion 5, thereby guiding the first connecting structure 2 and / or the second connecting structure 3 to a predetermined plug-in fitting position, and avoiding rigid contact and rigid friction between the first connecting structure 2 and the second connecting structure 3, realizing a flexible connection between the first connecting structure 2 and the second connecting structure 3, and reducing wear on the first connecting structure 2 and the second connecting structure 3.

[0092] It can be understood that during the plug-in process, the relative movement of the first connecting structure 2 and the second connecting structure 3 includes but is not limited to the first connecting structure 2 and the second connecting structure 3 can both rotate and / or both move, or only one of them can rotate and / or one of them moves, for example, the second connecting structure 3 in Figures 1 to 3 rotates and / or moves, and the present disclosure does not limit this.

[0093] As an exemplary embodiment, the first guide portion 4 is suitable for cooperating with the second guide portion 5 during the plug-in process of the first connecting structure 2 and the second connecting structure 3, so that the first connecting structure 2 and the second connecting structure 3 can rotate relative to each other, so as to guide the first connecting structure 2 and the second connecting structure 3 to a predetermined plug-in fitting position, and buffer the impact force of the first connecting structure 2 and the second connecting structure 3 by the relative rotation of the first connecting structure 2 and the second connecting structure 3.

[0094] In the present disclosure, there is no limitation on the direction of the rotation axis of the first connection structure 2 and / or the second connection structure 3 (such as the second connection structure 3 shown in Figures 1 to 3). In some embodiments, in an exemplary embodiment of the present disclosure, the first guide portion 4 is suitable for cooperating with the second guide portion 5 during the plug-in process of the first connection structure 2 and the second connection structure 3, so that the first connection structure 2 and the second connection structure 3 can rotate relative to each other around the plug-in direction Z of the first connection structure 2 and the second connection structure 3. For example, as shown in Figures 1 to 3, the second connection structure 3 can rotate relative to each other around the plug-in direction Z of the first connection structure 2 and the second connection structure 3, so as to decompose the impact force of the first connection structure 2 and the second connection structure 3 along the plug-in direction Z of the first connection structure 2 and the second connection structure 3, thereby buffering the impact force of the first connection structure 2 and the second connection structure 3. In this embodiment, the direction of the rotation axis of the first connection structure 2 or the second connection structure 3 is consistent with the plug-in direction Z.

[0095] It is understood that in other embodiments of the present disclosure, the direction of the rotation axis of the first connecting structure 2 and / or the second connecting structure 3 may form an angle other than 90° with the plugging direction Z. That is, the direction of the rotation axis of the first connecting structure 2 or the second connecting structure 3 may intersect with (not be parallel to) the plugging direction Z.

[0096] In the present disclosure, in order to further buffer the impact force of the first connecting structure 2 and the second connecting structure 3 along the plug-in direction Z and enhance the effect of the flexible connection. In some embodiments, as shown in Figures 1, 5 and 7, the connecting structure further includes an elastic member 9. The elastic member 9 is used to provide an elastic force in the opposite direction of rotation of the first connecting structure 2 and / or the second connecting structure 3 during the relative rotation of the first connecting structure 2 and the second connecting structure 3. That is, the impact force of the first connecting structure 2 and the second connecting structure 3 along the plug-in direction Z causes the first connecting structure 2 and the second connecting structure 3 to rotate relative to each other, and the elastic force provided by the elastic member 9 can slow down the relative rotation of the first connecting structure 2 and the second connecting structure 3, so as to further buffer the impact force, further enhance the effect of the flexible connection of the first connecting structure 2 and the second connecting structure 3, and enhance the stability of the first connecting structure 2 and the second connecting structure 3 during the plug-in process. In addition, the elastic member 9 can also keep the first connecting structure 2 and the second connecting structure 3 in the initial plug-in position, so as to facilitate the plug-in of the first connecting structure 2 and the second connecting structure 3 along the plug-in direction Z.

[0097] To facilitate the connection between the first connection structure 2 and the second connection structure 3, in some embodiments, in one embodiment of the present disclosure, as shown in FIG1 , the first connection structure 2 includes a first mounting member 202 and a first connection member 201, wherein the first connection member 201 is mounted on the first mounting member 202, and the first guide portion 4 is provided on the first mounting member 202; the second connection structure 3 includes a second mounting member 302 and a second connection member 302, wherein the second connection member 301 is mounted on the second mounting member 302, and the second guide portion 5 is provided on the second mounting member 302. The first mounting member 202 can rotate relative to the first connection member 201, and / or the second mounting member 302 can rotate relative to the second connection member 301. That is to say, the first guide portion 4 is not provided on the first connecting member 201, and the second guide portion 5 is not provided on the second connecting member 301. In this way, the structure of the first connecting member 201 and the second connecting member 301 can be left unchanged, thereby ensuring the reliability of the connection (such as electrical connection) between the first connecting member 201 and the second connecting member 301. In addition, the restrictions on the structure and material used by the first guide portion 4 and the second guide portion 5 can be reduced. It is only necessary that the structure and material used by the guide portion do not affect the reliability of the connection (such as electrical connection) between the first connecting member 201 and the second connecting member 301. In addition, the first mounting member 202 can rotate relative to the first connecting member 201, or the second mounting member 302 can rotate relative to the second connecting member 301, or the first mounting member 202 can rotate relative to the first connecting member 201, and the second mounting member 302 can rotate relative to the second connecting member 301, which is conducive to further realizing the flexible connection between the first connecting structure 2 and the second connecting structure 3.

[0098] In some embodiments, the first connector 201 is adapted to be plugged into and mated with the second connector 301 to achieve an electrical connection between the two modules 1. As mentioned above, the flexible connection between the first connection structure 2 and the second connection structure 3 can reduce the impact force during the plug-in mating of the first connector 201 and the second connector 301, thereby reducing wear on the first connector 201 and the second connector 301, thereby ensuring the service life of the first connector 201 and the second connector 301 and the reliability of the electrical connection between the first connector 201 and the second connector 301.

[0099] It should be noted that when the first connector 201 and the second connector 301 are plugged in, the first mounting member 202 and the second mounting member 302 can also be plugged in. Therefore, when the first connector 201 and the second connector 301 are plugged in, the first mounting member 202 can be mounted on the outside of the second mounting member 302, or the second mounting member 302 can be mounted on the outside of the first mounting member 202.

[0100] The present disclosure does not limit the specific structure of the second mounting member 302. In some embodiments, as shown in Figure 1, the second mounting member 302 includes a first cylindrical portion 3021, which is sleeved on the outside of the second connecting member 301, so that the first cylindrical portion 3021 can protect the second connecting member 301.

[0101] 1 and 5 , in some embodiments, in one implementation of the present disclosure, the second mounting member 302 further includes a mounting seat 3022, which is adapted to be mounted on a corresponding module 1 (e.g., the module 1 located below in FIG. 1 ), and the first cylindrical portion 3021 is rotatably connected to the mounting seat 3022 about a plugging direction Z. In other words, the first cylindrical portion 3021 can be rotatably connected to the corresponding module 1 via the mounting seat 3022, thereby reducing changes to the original structure of the module 1.

[0102] In order to further reduce the impact force during the plugging and mating of the first connector 201 and the second connector 301, as shown in FIG5 , an elastic member 9 is disposed between the first cylindrical portion 3021 and the mounting seat 3022, and is used to provide an elastic force in the opposite direction of rotation of the first cylindrical portion 3021 during the process of the first cylindrical portion 3021 rotating about the plugging direction Z. With this arrangement, during the plugging and mating of the first connector 201 and the second connector 301, on the basis of the first cylindrical portion 3021 rotating and / or moving to mitigate the impact force, the elastic force provided by the elastic member 9 to mitigate the rotation of the first cylindrical portion 3021 further reduces the impact of the impact force during the plugging and mating, thereby facilitating the smooth guidance of the first connector 201 and the second connector 301 to the predetermined plugging and mating position and improving the effect of the flexible connection.

[0103] The present disclosure does not limit the specific type of elastic member 9 and its mounting structure. In some embodiments, referring to Figures 5 and 7, in one embodiment of the present disclosure, a slide 10 and a stop portion 11 are provided on the mounting seat 3022. The stop portion 11 has a first stop surface 1101 and a second stop surface 1102 opposite each other. One end of the slide 10 extends to the first stop surface 1101, and the other end of the slide 10 extends to the second stop surface 1102. The end surface of the first cylindrical portion 3021, which is adapted to be connected to the mounting seat 3022, is provided with a recess 12. The recess 12 has a first side wall 1201 and a second side wall 1202 opposite each other in the circumferential direction. One end of the elastic member 9 abuts the first stop surface 1101, and the other end abuts the first side wall 1201. The second stop surface 1102 is adapted to abut the second side wall 1202. That is, in the present disclosure, the arc length of the recess 12 is greater than the arc length of the stopper 11, the end of the first cylindrical portion 3021 connected to the mounting seat 3022 can be snapped into the chute 10, and the recess 12 can be snapped into the outside of the stopper 11, and the elastic member 9 can be disposed in the chute 10 and between the recess 12 and the stopper 11. With this arrangement, during the rotation of the first cylindrical portion 3021 about the insertion direction Z, the first sidewall 1201 of the recess 12 squeezes the elastic member 9, causing the elastic member 9 to compress and generate resistance, thereby slowing down the rotation speed of the first cylindrical portion 3021 and further reducing the impact force.

[0104] As an exemplary embodiment, the elastic member 9 may be a spring. When the first cylindrical portion 3021 is not rotating, the spring may be in a free state within the chute 10, where the spring is neither stretched nor compressed. Furthermore, in the free state, the first cylindrical portion 3021 may be in an initial position, which is a position where the first guide portion 4 and the second guide portion 5 can align and abut against each other when the first connecting structure 2 and the second connecting structure 3 are plugged together along the plugging direction Z. It should be noted that after the first connecting member 201 and the second connecting member 301 are plugged together, although the spring is compressed, the elastic force generated by the spring is insufficient to drive the first cylindrical portion 3021 to rotate, thereby preventing any impact on the plugging and mating of the first and second connecting members 201, 301. When the first and second connecting members 201, 301 are disengaged, the first cylindrical portion 3021 can rotate back to its initial position under the elastic force of the spring.

[0105] Here, in order to further reduce the wear of the first connector 201 and the second connector 301 during the plug-in mating process, in some embodiments, a first distance is defined between the first end of the first guide portion 4 and the first end of the first mounting member 202, a second distance is defined between the first end of the first connector 201 and the first end of the first mounting member 202, and the first distance is less than the second distance; a third distance is defined between the first end of the second guide portion 5 and the first end of the second mounting member 302, a fourth distance is defined between the first end of the second connector 301 and the first end of the second mounting member 302, and the third distance is less than the fourth distance. Among them, the first end of the first guide portion 4, the first end of the first connecting member 201, and the first end of the first mounting member 202 are respectively in the plug-in direction Z, and the first guide portion 4, the first connecting member 201, and the first mounting member 202 are respectively close to one end of the second connecting structure 3; the first end of the second guide portion 5, the first end of the second connecting member 301, and the first end of the second mounting member 302 are respectively in the plug-in direction Z, and the second guide portion 5, the second connecting member 301, and the first mounting member 202 are respectively close to one end of the first connecting structure 2.

[0106] In other words, the position of the first guide portion 4 on the first mounting member 202 and the position of the second guide portion 5 on the first mounting member 202 are set so that, during the plugging process, the contact between the first guide portion 4 and the second guide portion 5 occurs before the contact between the first connecting member 201 and the second connecting member 301. With this arrangement, before the contact between the first connecting member 201 and the second connecting member 301, the first guide portion 4 and the second guide portion 5 can cause the first connecting structure 2 and the second connecting structure 3 to rotate relative to each other, thereby reducing the impact force when the first connecting member 201 and the second connecting member 301 are plugged in and mated, and further reducing the wear of the first connecting member 201 and the second connecting member 301.

[0107] The present disclosure does not limit the specific structure of the first mounting member 202. In some embodiments, as shown in FIG1 , the first mounting member 202 includes a second cylindrical portion 2021, which is sleeved on the outside of the first connecting member 201, so that the second cylindrical portion 2021 can protect the first connecting member 201. Here, the second cylindrical portion 2021 is fixedly disposed inside the corresponding module 1, and the present disclosure does not limit the method for fixing the second cylindrical portion 2021 inside the module 1. As an exemplary embodiment, the second cylindrical portion 2021 can be welded inside the module 1.

[0108] It is understood that, in the case where the first mounting member 202 can be fixedly mounted on the module 1 and the second mounting member 302 can be rotatably mounted on the module 1 about the plugging direction Z, in some embodiments, the inner wall of the second cylindrical portion 2021 is provided with a first protrusion or a first groove configured as the first guide portion 4, or the outer wall of the second cylindrical portion 2021 is provided with a first protrusion or a first groove configured as the first guide portion 4, the first protrusion or the first groove being provided with a first guiding slope 6, and the first guiding slope 6 being arranged at an angle with respect to the plugging direction Z. During the plugging process, the first guiding slope 6 is adapted to cooperate with the second guiding portion 5 to guide the second mounting member 302 in rotation about the plugging direction Z. That is, for example, referring to Figures 1 to 3, in some embodiments, the first guiding portion 4 can be a first protrusion, which can be provided on the inner wall of the second cylindrical portion 2021 and located between the inner wall of the second cylindrical portion 2021 and the first connector 201, or can be provided on the outer wall of the second cylindrical portion 2021, with the first protrusion provided with the first guiding slope 6.

[0109] In other embodiments, the first guide portion 4 can be a first groove, which can be provided on the inner wall of the second cylindrical portion 2021 and located between the inner wall of the second cylindrical portion 2021 and the first connector 201, or can be provided on the outer wall of the second cylindrical portion 2021, and the first groove is provided with a first guiding slope 6. In the present disclosure, regardless of whether the first guide portion 4 is configured as a first protrusion or a first groove, during the plug-in mating process of the first connector 201 and the second connector 301, the first guiding slope 6 can cooperate with the second guide portion 5, and convert the movement of the second mounting member 302 along the plug-in direction Z into a spiral motion that rotates while approaching the first mounting member 202, so as to achieve the purpose of flexible connection by reducing the impact force when the first connector 201 and the second connector 301 are plugged in and mated in the process of guiding the first connecting structure 2 and the second connecting structure 3 to the predetermined plug-in mating position.

[0110] As an exemplary embodiment, the inner wall of the second cylindrical portion 2021 is provided with a first protrusion configured as a first guide portion 4. The shape of the first protrusion is not limited in the present disclosure. In some embodiments, as shown in FIG3 , the first protrusion can be configured as a strip, and the strip is arranged at an angle to the plug-in direction Z. The strip has a simple structure, and since the strip has a certain length along one direction, such a configuration can increase the length of the first guide bevel 6. During the plug-in mating process of the first connector 201 and the second connector 301, the time for the first guide bevel 6 to engage with the second guide portion 5 can be increased, so that the second mounting member 302 can continue to rotate, which is beneficial to further reduce the impact force when the first connector 201 and the second connector 301 are plugged in.

[0111] In order to enable the first guide bevel 6 to quickly cooperate with the second guide portion 5 (such as the second guide bevel 7 on the second guide portion 5 described below) when the first connecting member 201 is plugged into the second connecting member 301, in some embodiments, as shown in Figure 4, there are multiple first protrusions, and the multiple first protrusions are arranged at intervals along the circumference of the second cylindrical portion 2021.

[0112] In some embodiments, the outer wall of the first cylindrical portion 3021 is provided with a second protrusion or a second groove configured as the second guide portion 5, or the inner wall of the first cylindrical portion 3021 is provided with a second protrusion or a second groove configured as the second guide portion 5, and the second protrusion or the second groove is provided with a second guiding slope 7, and the second guiding slope 7 is arranged at an angle with the plugging direction Z. During the plugging process, the second guiding slope 7 is adapted to cooperate with the first guide portion 4 to guide the first cylindrical portion 3021 to rotate about the plugging direction Z. That is, for example, referring to Figures 1 to 3, in some embodiments, the second guiding portion 5 can be a second protrusion, which can be provided on the inner wall of the first cylindrical portion 3021 and located between the inner wall of the first cylindrical portion 3021 and the second connector 301, or can be provided on the outer wall of the first cylindrical portion 3021, and the second protrusion is provided with the second guiding slope 7 that facilitates cooperation with the first guiding slope 6.

[0113] In other embodiments, the second guide portion 5 can be a second groove, which can be provided on the inner wall of the second cylindrical portion 2021 and located between the inner wall of the second cylindrical portion 2021 and the first connector 201, or can be provided on the outer wall of the second cylindrical portion 2021, and the second groove is provided with a second guide slope 7 that is convenient for cooperating with the first guide slope 6. In the present disclosure, regardless of whether the second guide portion 5 is configured as a second protrusion or a second groove, during the plug-in mating process of the first connector 201 and the second connector 301, the second guide slope 7 can cooperate with the first guide portion 4, and convert the movement of the first cylindrical portion 3021 along the plug-in direction Z into a spiral motion while rotating and approaching the first mounting member 202, so as to achieve the purpose of reducing the impact force during the plug-in mating of the first connector 201 and the second connector 301 in the process of guiding the first connecting structure 2 and the second connecting structure 3 to the predetermined plug-in mating position.

[0114] In order to reduce the impact force of the first guide portion 4 on the second guide bevel 7 and facilitate the cooperation between the two, in some embodiments, as shown in FIG3 , the front end portion 8 of the second guide bevel 7 is constructed as an arcuate surface. The front end portion 8 is the end of the second guide bevel 7 that first contacts the first guide portion 4 during the plug-in process. In other words, during the contact between the first guide portion 4 and the second guide portion 5, the front end portion 8 of the arcuate surface can first contact the first guide portion 4 (such as the first guide bevel 6 of the first guide portion 4), which can buffer the impact force brought by the first guide portion 4, reduce the degree of damage to the first guide portion 4 and the second guide bevel 7, and facilitate the cooperation between the second guide bevel 7 and the first guide bevel 6.

[0115] In order to improve the impact resistance of the second protrusion, in some embodiments, as shown in FIG3 , the second protrusion has a first end (an upper end as shown in FIG3 ) and a second end (a lower end as shown in FIG3 ) relative to each other in the plug-in direction Z, and the cross-sectional area of ​​the second end is larger than the cross-sectional area of ​​the first end. The first end is the end of the second protrusion that first contacts the first guide portion 4 during the plug-in process. As an exemplary embodiment, the cross-sectional area of ​​the second protrusion gradually increases from the first end to the second end. The cross-sectional area of ​​the first end is smaller than the cross-sectional area of ​​the second end, which facilitates the formation of the above-mentioned second guide slope 7, and facilitates the guidance of the first mounting member 202 (such as the first guide portion 4 of the first mounting member 202) when the second protrusion cooperates with the first guide portion 4. In addition, the formation of the above-mentioned small upper and large lower structure is conducive to ensuring the reliability of the second protrusion when it is impacted.

[0116] In order to enable the second guide slope 7 to quickly cooperate with the first guide portion 4 when the first connecting member 201 and the second connecting member 301 are plugged into each other, in some embodiments, as shown in Figure 5, there are multiple second protrusions, and the multiple second protrusions are arranged at intervals along the circumference of the first cylindrical portion 3021.

[0117] In some embodiments, the number of the second protrusions is the same as the number of the first guide portions 4, and each second protrusion is suitable for cooperating with the corresponding first guide portion 4. In the present disclosure, based on the above-mentioned setting of the first guide portion 4 as the first protrusion, that is, the number of the second protrusions can be the same as the number of the first protrusions, and each second protrusion is suitable for cooperating with the corresponding first protrusion. During the plug-in and mating process of the first connector 201 and the second connector 301, the first guide bevel 6 of the first protrusion contacts the second guide bevel 7 of the second protrusion, so that the first cylindrical portion 3021 moves spirally toward the second cylindrical portion 2021 under the action of the first guide bevel 6 and the second guide bevel 7, so as to achieve the purpose of reducing the impact force when the first connector 201 and the second connector 301 are plugged in and mated. The provision of multiple first protrusions and multiple second protrusions can improve the reliability of guiding the rotation of the first cylindrical portion 3021.

[0118] As shown in Figures 5 to 8, in the present disclosure, the second mounting member 302 may further include a limiting assembly 3023, which is used to axially limit the first cylindrical portion 3021 on the mounting seat 3022 so that the first cylindrical portion 3021 can rotate relative to the mounting seat 3022 but will not separate from the mounting seat 3022.

[0119] The present disclosure does not limit the specific structure of the limiting assembly 3023. As an exemplary embodiment, as shown in Figures 5 to 8, the limiting assembly 3023 includes a limiting groove 30231 and a limiting protrusion 30232. The limiting protrusion 30232 is provided on one of the second stop surface 1102 and the second side wall 1202, and the limiting groove 30231 is provided on the other of the second stop surface 1102 and the second side wall 1202. The limiting protrusion 30232 is plugged into and engaged with the limiting groove 30231.

[0120] For example, referring to Figures 7 and 8, the limiting protrusion 30232 can be provided on the second stop surface 1102 and can extend within the chute 10 along the extension direction of the chute 10; the limiting groove 30231 can be provided on the second sidewall 1202 and can extend within the first cylindrical portion 3021 along the axial direction of the recess 12. When the first cylindrical portion 3021 is connected to the mounting seat 3022, the end of the first cylindrical portion 3021 connected to the mounting seat 3022 is engaged with the chute 10, the first sidewall 1201 of the recess 12 abuts against one end of the elastic member 9, and the elastic member 9 is engaged with the chute 10 between the recess 12 and the stop portion 11. The second sidewall 1202 of the recess 12 engages with the limiting protrusion 30232 on the second stop surface 1102 through the limiting groove 30231, thereby limiting the axial position of the first cylindrical portion 3021.

[0121] It can be understood that when the first side wall 1201 of the above-mentioned recess 12 abuts against one end of the elastic member 9, the elastic member 9 can be in a free state, and the second side wall 1202 of the recess 12 can be plugged into and matched with the limiting protrusion 30232 on the second stop surface 1102 through the limiting groove 30231; and when the first cylindrical portion 3021 rotates and the elastic member 9 is compressed, the limiting groove 30231 and the limiting protrusion 30232 have a sufficiently long matching length to adapt to the deformation of the elastic member 9, that is, when the elastic member 9 is continuously compressed, the limiting groove 30231 also has a sufficiently long length for the limiting protrusion 30232 to be inserted, and the limiting protrusion 30232 is always plugged into the limiting groove 30231, and will not affect the plug-in matching of the first connecting member 201 and the second connecting member 301.

[0122] In the present disclosure, it is considered that the modular components 1 can be mass-produced, that is, the position where the first connecting structure 2 is set on one modular component 1 can be preset, and the position where the second connecting structure 3 is set on another modular component 1 can also be preset. Generally speaking, during the process of connecting two modular components 1, the first connecting structure 2 and the second connecting structure 3 can be plugged in simply by aligning the two modular components 1. However, due to factors such as processing errors, there may be a deviation between the position where the first connecting structure 2 is set on one modular component 1 and the preset position, or the position where the second connecting structure 3 is set on the other modular component 1 and the preset position, thereby increasing the difficulty of aligning the first connecting structure 2 and the second connecting structure 3.

[0123] In the present disclosure, to improve the accuracy of the plugging of the first and second connecting structures 2 and 3 and reduce the probability of wear during the plugging process, and to achieve a flexible connection between the first and second connecting structures 2 and 3, in some embodiments, as shown in FIG1 , at least one of the first and second connecting structures 2 and 3 is adapted to be movably connected to the corresponding module 1 in a first direction X, thereby guiding the first and second connecting structures 2 and 3 to a predetermined plug-in mating position. The first direction X intersects with the plugging direction Z of the first and second connecting structures 2 and 3. With this arrangement, during the docking process of the first and second connecting structures 2 and 3, the movement of one or both of the first and second connecting structures 2 and 3 in the first direction X can, on the one hand, eliminate machining errors, and on the other hand, facilitate alignment of the first and second connecting structures 2 and 3, thereby improving the accuracy of the plugging of the first and second connecting structures 2 and 3. As an exemplary embodiment, the first direction X is perpendicular to the plugging direction Z of the first and second connecting structures 2 and 3, thereby enhancing the flexible connection effect of the first and second connecting structures 2 and 3.

[0124] In order to further improve the accuracy of the plugging of the first connecting structure 2 and the second connecting structure 3 and reduce the probability of the first connecting structure 2 and the second connecting structure 3 being worn during the plugging process, in some embodiments, as shown in Figure 1, at least one of the first connecting structure 2 and the second connecting structure 3 is suitable for being movably connected to the corresponding module 1 in the second direction Y. The second direction Y intersects with the first direction X, and the second direction Y and the first direction X are both located in a plane perpendicular to the plugging direction Z. Therefore, during the docking process of the first connecting structure 2 and the second connecting structure 3, one or both of the first connecting structure 2 and the second connecting structure 3 can be moved in the first direction X or the second direction Y in a plane perpendicular to the plugging direction Z to further eliminate processing errors and improve the accuracy of the plugging of the first connecting structure 2 and the second connecting structure 3. As an exemplary embodiment, the first direction X is orthogonal to the second direction Y.

[0125] Based on the electrical connection between the two modules 1 and the specific structure of the second connection structure 3, in some embodiments, as shown in FIG5 , the first cylindrical portion 3021 is movably connected to the mounting seat 3022 in a first direction X, where the first direction X intersects the plugging direction Z. The movement of the first cylindrical portion 3021 in the first direction X facilitates the plugging and mating of the second connector 301 with the first connection structure 2, thereby improving the precision of the plugging of the second connector 301 with the first connection structure 2.

[0126] In some embodiments, as shown in FIG5 , the mounting base 3022 includes a first mounting block 30221 and at least two second mounting blocks 30222. The first cylindrical portion 3021 is connected to the first mounting block 30221. The second connector 301 is fixed to the first mounting block 30221. For example, the second connector 301 is inserted into a retaining hole in the first mounting block 30221 to allow the second connector 301 to move with the first mounting block 30221 (in the first direction X and the second direction Y as described below). The second mounting blocks 30222 are adapted to be mounted to corresponding modules 1. The two second mounting blocks 30222 are spaced apart along the first direction X. Each second mounting block 30222 is provided with a step 13 on a side facing away from the first connecting structure 2. A receiving space 14 is defined between the two step portions 13. The length of the receiving space 14 in the first direction X is greater than the length of the first mounting block 30221 in the first direction X. Thus, the first mounting block 30221 can be accommodated within the accommodation space 14 between the two stepped portions 13. This prevents the first mounting block 30221 from disengaging from the accommodation space 14 along the insertion direction Z. Furthermore, the first mounting block 30221 can move within the accommodation space 14 along the first direction X, thereby eliminating machining errors between the first connecting structure 2 and the second connecting structure 3 in the first direction X. Here, the second mounting block 30222 is fixedly disposed on the exterior of the corresponding module 1, and the present disclosure does not limit the manner in which the second mounting block 30222 is secured to the exterior of the module 1. As an exemplary embodiment, the second mounting block 30222 can be secured to the exterior of the module 1 via bolts.

[0127] To facilitate the formation of the aforementioned accommodation space 14, in some embodiments, as shown in FIG. 1 , a cavity 15 is provided on the module 1 for mounting the first connecting structure 2 or the second connecting structure 3, and the second mounting block 30222 can be mounted within the cavity 15 of the module 1. The two steps 13 and the inner wall of the cavity 15 together define the accommodation space 14. The length of the accommodation space 14 in the second direction Y is greater than the length of the first mounting block 30221 in the second direction Y. Furthermore, both the second direction Y and the first direction X lie in a plane perpendicular to the insertion direction Z. In other words, after the first mounting block 30221 is accommodated in the accommodation space 14, the first mounting block 30221 can move within the accommodation space 14 in the first direction X or the second direction Y to eliminate machining errors. Furthermore, the accommodation space 14 can also limit the length of movement of the first mounting block 30221 in the first direction X or the second direction Y, thereby preventing the first mounting block 30221 from escaping from the accommodation space 14 in the first direction X or the second direction Y.

[0128] In the present disclosure, the first connection structure 2 can be provided on one module 1 to form a module assembly, and the second connection structure 3 can be provided on another module 1 to form another module assembly. During installation, the two modules can be assembled to form the following modular device.

[0129] According to the second aspect of the present disclosure, a module device is provided, which includes the above-mentioned connecting structure and multiple module parts 1, at least two adjacent module parts 1 among the multiple module parts 1 are connected by a connecting structure, and at least one of the first connecting structure 2 and the second connecting structure 3 is movably arranged on the corresponding module part 1.

[0130] In the present disclosure, as an exemplary embodiment, a module device may be an energy storage device, and a module 1 may be a battery module. Any two adjacent modules 1 within the plurality of modules 1 are electrically connected via a connection structure. In other words, the electrical connection of the connection structure enables the electrical connection of the plurality of modules 1 to form an energy storage cabinet capable of supplying external power, such as a power supply cabinet or a battery pack.

[0131] To facilitate electrical connection between multiple modules 1, in some embodiments, one of any two adjacent modules 1 connected by a connection structure is provided with a first via, and the other is provided with a second via. The first connection structure 2 includes a first connector 201, which passes through the first via and is electrically connected to the electrical components within the corresponding module 1. The second connection structure 3 includes a second connector 301, which passes through the second via and is electrically connected to the electrical components within the corresponding module 1. With this arrangement, the electrical components within the module 1 corresponding to the first connector 201 are electrically connected to the module 1 corresponding to the second connector 301 through the plug-in connection of the first connector 201 and the second connector 301. Here, the above-mentioned second cylindrical portion 2021 is provided with a first through hole connected to the first through hole, so that the first connecting member 201 passes through the first through hole and the second through hole respectively and is electrically connected to the electrical components inside the corresponding module component 1; the above-mentioned first cylindrical portion 3021 is provided with a second through hole and the first mounting block 30221 is provided with a third through hole, and the second through hole, the third through hole and the second through hole are connected to each other, so that the second connecting member 301 passes through the second through hole, the second through hole and the third through hole respectively and is electrically connected to the electrical components inside the corresponding module component 1.

[0132] The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings. However, the present disclosure is not limited to the specific details of the above embodiments. Within the technical concept of the present disclosure, various simple modifications can be made to the technical solutions of the present disclosure, and these simple modifications all fall within the scope of protection of the present disclosure.

[0133] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any appropriate manner without contradiction. In order to avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.

[0134] In addition, the various embodiments of the present disclosure may be arbitrarily combined, and as long as they do not violate the concept of the present disclosure, they should also be regarded as the contents disclosed by the present disclosure.
