Detailed Implementation

[0084] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0085] In this disclosure, unless otherwise stated, directional terms such as "above" and "below" are generally defined with respect to the orientation of the corresponding drawings, and are used only for the convenience of describing this disclosure and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or a specific orientation construction and operation, and therefore should not be construed as a limitation of this disclosure. "Inner" and "outer" refer to the inside and outside of the outline of the corresponding component. The terms "first," "second," etc., are used to distinguish different components and do not have sequential or importance implications. (The attached figures...) Figure 1The X direction shown can be a first direction, the Y direction can be a second direction, and the Z direction can be the insertion direction of the first connecting structure 2 and the second connecting structure 3. Furthermore, in the following description, unless otherwise explained, the same reference numerals in different figures denote the same or similar elements when referring to the accompanying drawings.

[0086] In the description of this disclosure, it should also be noted that, unless otherwise expressly specified and limited, the terms "set up," "connect," "link," and "install" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this disclosure according to the specific circumstances.

[0087] As mentioned above, in related technologies, connectors are prone to wear during the alignment and insertion process. Research has found that the reason for this easy friction is that, due to the heavy weight of the modular components and the inconvenience of moving and aligning them, there may be instances where the insertion positions of the two connectors are not aligned, but they are directly mated together. During subsequent adjustments to the insertion positions, the rigid contact between the two connectors easily causes wear. Furthermore, during the insertion process, the two connectors are directly and rigidly connected along their insertion direction, resulting in rigid contact and friction, which easily leads to wear. This shortens the lifespan of the connectors and reduces the reliability of the connection.

[0088] In view of this, such as Figures 1 to 9 As shown, this disclosure provides a connection structure, including a first connection structure 2 and a second connection structure 3. The first connection structure 2 is adapted to be disposed in a module 1 (such as...). Figure 1 On the module 1 located at the top of the drawing, the second connecting structure 3 is adapted to be installed on another module 1 (such as...). Figure 1The module 1 located at the bottom of the drawing is used to insert and mate with the first connecting structure 2. The first connecting structure 2 and the second connecting structure 3 can cooperate with each other during insertion, allowing the first connecting structure 2 to move relative to the module 1 on which it is located and / or allowing the second connecting structure 3 to move relative to the module 1 on which it is located, thereby enabling relative movement of the first connecting structure 2 and the second connecting structure 3 and guiding the first connecting structure 2 and / or the second connecting structure 3 to a predetermined insertion and mating position. Through the above technical solution, during the connection of the two modular components 1, the first connecting structure 2 can move relative to the modular component 1 on which the first connecting structure 2 is provided, or the second connecting structure 3 can move relative to the modular component 1 on which the second connecting structure 3 is provided, or the first connecting structure 2 can move relative to the modular component 1 on which the first connecting structure 2 is provided, and the second connecting structure 3 can move relative to the modular component 1 on which the second connecting structure 3 is provided, so that the first connecting structure 2 and the second connecting structure 3 can move relative to each other, thereby facilitating the guidance of the first connecting structure 2 and the second connecting structure 3 to the predetermined insertion and mating position, which can improve the convenience of connecting the first connecting structure 2 and the second connecting structure 3. At the same time, it can also eliminate the step of adjusting the insertion position of the first connecting structure 2 and the second connecting structure 3, thereby avoiding wear of the first connecting structure 2 and the second connecting structure 3 caused by subsequent adjustment of the insertion position.

[0089] Furthermore, compared to the rigid insertion method of two connectors in related technologies (where the two connectors cannot rotate or move), in this disclosure, since the first connecting structure 2 and the second connecting structure 3 can move relative to each other during the insertion process, the impact force of the first connecting structure 2 and the second connecting structure 3 during the insertion process can be buffered, avoiding rigid contact and rigid friction between the first connecting structure 2 and the second connecting structure 3. This facilitates the flexible connection of the first connecting structure 2 and the second connecting structure 3, reduces the wear of the first connecting structure 2 and the second connecting structure 3, thereby extending the service life of the first connecting structure 2 and the second connecting structure 3 and improving the reliability of the connection between the first connecting structure 2 and the second connecting structure 3.

[0090] It should be noted that a flexible connection refers to a connection method in which the connecting parts are deformed or displaced at an angle to the connection direction, so as to buffer the impact force along the connection direction during the connection process. In this disclosure, the first connecting structure 2 and the second connecting structure 3 can cooperate with each other during the insertion process, so that the first connecting structure 2 can move relative to the module 1 on which the first connecting structure 2 is provided and / or the second connecting structure 3 can move relative to the module 1 on which the second connecting structure 3 is provided. The way in which the first connecting structure 2 and the second connecting structure 3 can move relative to each other is called a flexible connection.

[0091] It is understood that the first connecting structure 2 being movable relative to the module 1 on which it is provided can mean that the first connecting structure 2 as a whole is movable relative to the module 1, or that some components of the first connecting structure 2 are movable relative to the module 1. Similarly, the second connecting structure 3 being movable relative to the module 1 on which it is provided can mean that the second connecting structure 3 as a whole is movable relative to the module 1, or that some components of the second connecting structure 3 are movable relative to the module 1. This disclosure does not limit this.

[0092] Furthermore, it is understood that in this disclosure, 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. Module 1 can be any component that is suitable for connection using the connection structure provided in this disclosure, and module 1 includes, but is not limited to, a battery module.

[0093] In this disclosure, any suitable structure can be provided on the connection structure to achieve the above-mentioned scheme that allows the first connection structure 2 and the second connection structure 3 to move relative to each other and guide the first connection structure 2 and / or the second connection structure 3 to a predetermined mating position; this disclosure does not limit this. Optionally, as Figure 1 and Figure 2As shown, the first connecting structure 2 is provided with a first guide portion 4, and the second connecting structure 3 is provided with a second guide portion 5. The first guide portion 4 is adapted to cooperate with the second guide portion 5 during the insertion process of the first connecting structure 2 and the second connecting structure 3, so that the first connecting structure 2 can move relative to the module 1 on which the first connecting structure 2 is provided and / or the second connecting structure 3 can move relative to the module 1 on which the second connecting structure 3 is provided, thereby allowing the first connecting structure 2 and the second connecting structure 3 to move relative to each other and guiding the first connecting structure 2 and / or the second connecting structure 3 to a predetermined insertion and engagement position. With this configuration, during the insertion and engagement process of the two module 1, the guiding cooperation of the first guide portion 4 and the second guide portion 5 allows the first connecting structure 2 and the second connecting structure 3 to move relative to each other, thereby guiding the first connecting structure 2 and / or the second connecting structure 3 to a predetermined insertion and engagement position, 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.

[0094] It is understood that during the insertion process, the relative movement of the first connecting structure 2 and the second connecting structure 3 can take the form of, but is not limited to, both the first connecting structure 2 and the second connecting structure 3 rotating and / or both moving, or only one of them rotating and / or moving, for example... Figures 1 to 3 The second connecting structure 3 in the middle can rotate and / or move, but this disclosure does not limit it.

[0095] As an exemplary embodiment, the first guide portion 4 is adapted to cooperate with the second guide portion 5 during the insertion 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 insertion position, and to buffer the impact force of the first connecting structure 2 and the second connecting structure 3 by means of relative rotation of the first connecting structure 2 and the second connecting structure 3.

[0096] In this disclosure, for the first connecting structure 2 and / or the second connecting structure 3 (such as...) Figures 1 to 3 The direction of the rotation axis of the second connecting structure 3 shown is not limited. Optionally, in an exemplary embodiment of this disclosure, the first guide portion 4 is adapted to cooperate with the second guide portion 5 during the insertion 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 about the insertion direction Z of the first connecting structure 2 and the second connecting structure 3, for example, as Figures 1 to 3As shown, the second connecting structure 3 is able to rotate relative to the insertion direction Z of the first connecting structure 2 and the second connecting structure 3, so as to decompose the impact force of the first connecting structure 2 and the second connecting structure 3 along the insertion direction Z, thereby buffering the impact force of the first connecting structure 2 and the second connecting structure 3. In this embodiment, the direction of the rotation axis of the first connecting structure 2 or the second connecting structure 3 is consistent with the insertion direction Z.

[0097] It is understood that, in other embodiments of this 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 insertion direction Z. That is, the direction of the rotation axis of the first connecting structure 2 or the second connecting structure 3 may intersect (not be parallel to) the insertion direction Z.

[0098] In this disclosure, to further buffer the impact force on the first connecting structure 2 and the second connecting structure 3 along the insertion direction Z, and to improve the effect of the flexible connection, optionally, as follows... Figure 1 , Figure 5 and Figure 7 As shown, the connecting structure also includes an elastic element 9. The elastic element 9 provides an elastic force opposite to the rotation direction of the first connecting structure 2 and / or the second connecting structure 3 during relative rotation of the first connecting structure 2 and the second connecting structure 3. That is, the impact force along the insertion direction Z of the first connecting structure 2 and the second connecting structure 3 causes relative rotation, and the elastic force provided by the elastic element 9 can mitigate this relative rotation, further buffering the impact force and improving the flexible connection effect of the first connecting structure 2 and the second connecting structure 3, thus enhancing the stability during insertion. In addition, the elastic element 9 can also keep the first connecting structure 2 and the second connecting structure 3 in their initial insertion position, facilitating insertion along the insertion direction Z.

[0099] To facilitate the connection between the first connecting structure 2 and the second connecting structure 3, optionally, in one embodiment of this disclosure, such as Figure 1As shown, the first connecting structure 2 includes a first mounting member 202 and a first connecting member 201, with the first connecting member 201 mounted on the first mounting member 202 and a first guide portion 4 disposed on the first mounting member 202; the second connecting structure 3 includes a second mounting member 302 and a second connecting member 302, with the second connecting member 301 mounted on the second mounting member 302 and a second guide portion 5 disposed on the second mounting member 302. The first mounting member 202 is rotatable relative to the first connecting member 201, and / or the second mounting member 302 is rotatable relative to the second connecting member 301. In other words, the first guide portion 4 is not provided on the first connector 201, and the second guide portion 5 is not provided on the second connector 301. This allows for the absence of structural modifications to the first connector 201 and the second connector 301, ensuring the reliability of the connection (e.g., electrical connection) between the two connectors. Furthermore, it reduces the limitations on the structure and materials used for the first guide portion 4 and the second guide portion 5, as long as the structure and materials used for the guide portions do not affect the reliability of the connection (e.g., electrical connection) between the first connector 201 and the second connector 301. Additionally, the first mounting member 202 can rotate relative to the first connector 201, or the second mounting member 302 can rotate relative to the second connector 301, or both the first mounting member 202 and the second mounting member 302 can rotate relative to the second connector 301. This facilitates a more flexible connection between the first connecting structure 2 and the second connecting structure 3.

[0100] Optionally, in one embodiment of this disclosure, the first connector 201 is adapted to be inserted into the second connector 301 to achieve an electrical connection between the two module components 1. As mentioned above, the flexible connection between the first connecting structure 2 and the second connecting structure 3 can reduce the impact force when the first connector 201 and the second connector 301 are inserted into each other, reduce the wear of the first connector 201 and the second connector 301, and ensure 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.

[0101] It should be noted that when the first connector 201 and the second connector 301 are plugged in, the first mounting part 202 and the second mounting part 302 can also be plugged in. Therefore, when the first connector 201 and the second connector 301 are plugged in, the first mounting part 202 can be fitted over the second mounting part 302, or the second mounting part 302 can be fitted over the first mounting part 202.

[0102] This disclosure does not limit the specific structure of the second mounting component 302; alternatively, such as... Figure 1As shown, the second mounting member 302 includes a first cylindrical portion 3021, which is sleeved on the outside of the second connector 301, so that the first cylindrical portion 3021 can protect the second connector 301.

[0103] See Figure 1 and Figure 5 Optionally, in one embodiment of this disclosure, the second mounting member 302 further includes a mounting base 3022, which is adapted to be mounted to the corresponding module member 1 (e.g., Figure 1 On the module 1 located below in the drawing direction, the first cylindrical portion 3021 is rotatably connected to the mounting base 3022 about the insertion direction Z. In other words, the first cylindrical portion 3021 can be rotatably connected to the corresponding module 1 via the mounting base 3022, which can reduce changes to the original structure of the module 1.

[0104] To further reduce the impact force when the first connector 201 and the second connector 301 are inserted and mated, such as Figure 5 As shown, the elastic element 9 is disposed between the first cylindrical portion 3021 and the mounting base 3022, and is used to provide an elastic force opposite to the rotation direction of the first cylindrical portion 3021 during the rotation of the first cylindrical portion 3021 around the insertion direction Z. With this configuration, during the insertion and engagement of the first connector 201 and the second connector 301, in addition to the rotation and / or movement of the first cylindrical portion 3021 to mitigate impact, the elastic force provided by the elastic element 9 further reduces the impact of the impact force during the insertion and engagement, facilitating the smooth guidance of the first connector 201 and the second connector 301 to the predetermined insertion and engagement position, while also improving the effect of the flexible connection.

[0105] This disclosure does not limit the specific type of the elastic element 9 or its mounting structure. Optionally, see [link to relevant documentation]. Figure 5 and Figure 7In one embodiment of this disclosure, the mounting base 3022 is provided with a sliding groove 10 and a stop portion 11. The stop portion 11 has opposing first stop surfaces 1101 and second stop surfaces 1102. One end of the sliding groove 10 extends to the first stop surface 1101, and the other end of the sliding groove 10 extends to the second stop surface 1102. The end face of the first cylindrical portion 3021 adapted to be connected to the mounting base 3022 is provided with a recess 12. The recess 12 has opposing first sidewalls 1201 and second sidewalls 1202 in the circumferential direction. One end of the elastic member 9 abuts against the first stop surface 1101, and the other end abuts against the first sidewall 1201. The second stop surface 1102 is adapted to abut against the second sidewall 1202. In other words, in this disclosure, the arc length of the recess 12 is greater than the arc length of the stop 11. One end of the first cylindrical portion 3021 connected to the mounting base 3022 can be engaged in the slide groove 10, and the recess 12 can be engaged outside the stop 11. The elastic member 9 can be disposed in the slide groove 10 and located between the recess 12 and the stop 11. With this configuration, during the rotation of the first cylindrical portion 3021 around the insertion direction Z, the first sidewall 1201 of the recess 12 compresses 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.

[0106] As an exemplary embodiment, the elastic element 9 can be a spring. When the first cylindrical portion 3021 is not rotated, the spring can be in a free state within the groove 10. This free state means that the spring is neither stretched nor compressed. Furthermore, in the free state of the spring, the first cylindrical portion 3021 can be in an initial position, which is the 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 inserted along the insertion direction Z. It should be noted that after the first connecting member 201 and the second connecting member 301 complete the insertion engagement, although the spring will be in a compressed state, the elastic force generated by the spring at this time is insufficient to drive the first cylindrical portion 3021 to rotate, thus avoiding any impact on the insertion engagement of the first connecting member 201 and the second connecting member 301. When the first connecting member 201 and the second connecting member 301 disengage from the insertion engagement, the first cylindrical portion 3021 can rotate back to its initial position under the action of the spring's elastic force.

[0107] Here, in order to further reduce wear on the first connector 201 and the second connector 301 during the insertion and mating process, optionally, the distance between the first end of the first guide portion 4 and the first end of the first mounting member 202 is a first distance, and the distance between the first end of the first connector 201 and the first end of the first mounting member 202 is a second distance, the first distance being smaller than the second distance; the distance between the first end of the second guide portion 5 and the first end of the second mounting member 302 is a third distance, and the distance between the first end of the second connector 301 and the first end of the second mounting member 302 is a fourth distance, the third distance being smaller than the fourth distance. Wherein, the first end of the first guide part 4, the first end of the first connector 201, and the first end of the first mounting part 202 are respectively in the insertion direction Z, and the first guide part 4, the first connector 201, and the first mounting part 202 are each close to one end of the second connecting structure 3; the first end of the second guide part 5, the first end of the second connector 301, and the first end of the second mounting part 302 are respectively in the insertion direction Z, and the second guide part 5, the second connector 301, and the first mounting part 202 are each close to one end of the first connecting structure 2.

[0108] In other words, the positions of the first guide portion 4 and the second guide portion 5 on the first mounting member 202 are configured such that, during the insertion process, the contact between the first guide portion 4 and the second guide portion 5 occurs before the contact between the first connector 201 and the second connector 301. With this configuration, before the contact between the first connector 201 and the second connector 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 connector 201 and the second connector 301 are inserted and engaged, and further reducing the wear of the first connector 201 and the second connector 301.

[0109] This disclosure does not limit the specific structure of the first mounting component 202; alternatively, as... Figure 1 As shown, the first mounting member 202 includes a second cylindrical portion 2021, which is sleeved on the outside of the first connecting member 201, thereby protecting the first connecting member 201. Here, the second cylindrical portion 2021 is fixedly disposed inside the corresponding module 1, and this disclosure does not limit the fixing method of 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.

[0110] Understandably, when the first mounting member 202 can be fixedly mounted on the module 1 and the second mounting member 302 can be rotatably disposed on the module 1 about the insertion direction Z, optionally, the inner wall of the second cylindrical portion 2021 is provided with a first protrusion or a first groove configured as a 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 a first guide portion 4, the first protrusion or the first groove being provided with a first guide slope 6, the first guide slope 6 being angled to the insertion direction Z. During the insertion process, the first guide slope 6 is adapted to cooperate with the second guide portion 5 to guide the second mounting member 302 to rotate about the insertion direction Z. That is, for example, see Figures 1 to 3 In some embodiments, the first guide portion 4 may be a first protrusion. The first protrusion may be disposed 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 it may be disposed on the outer wall of the second cylindrical portion 2021. The first protrusion is provided with a first guide slope 6.

[0111] In other embodiments, the first guide portion 4 can be a first groove, which can be disposed 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 it can be disposed on the outer wall of the second cylindrical portion 2021. A first guide slope 6 is provided on the first groove. In this disclosure, regardless of whether the first guide portion 4 is constructed as a first protrusion or a first groove, during the insertion and engagement of the first connector 201 and the second connector 301, the first guide slope 6 can cooperate with the second guide portion 5, and cause the movement of the second mounting member 302 along the insertion direction Z to be converted into a spiral movement that rotates while approaching the first mounting member 202. This reduces the impact force when the first connector 201 and the second connector 301 are inserted and engaged during the process of guiding the first connecting structure 2 and the second connecting structure 3 to the predetermined insertion and engagement position, thereby achieving the purpose of flexible connection.

[0112] 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 this disclosure; alternatively, such as… Figure 3 As shown, the first protrusion can be constructed as a strip, which is arranged at an angle to the insertion direction Z. The strip structure is simple, and since the strip has a certain length along one direction, this arrangement can increase the length of the first guide slope 6. During the insertion and engagement of the first connector 201 and the second connector 301, the engagement time between the first guide slope 6 and the second guide portion 5 can be increased, allowing the second mounting member 302 to rotate continuously. This further helps to reduce the impact force when the first connector 201 and the second connector 301 are inserted and engaged.

[0113] In order for the first guide ramp 6 to quickly engage with the second guide portion 5 (such as the second guide ramp 7 on the second guide portion 5 as described below) when the first connector 201 and the second connector 301 are inserted and engaged, optionally, as Figure 4 As shown, there are multiple first protrusions, which are arranged at intervals along the circumference of the second cylindrical portion 2021.

[0114] Optionally, the outer wall of the first cylindrical portion 3021 is provided with a second protrusion or a second groove configured as a 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 a second guide portion 5, and the second protrusion or the second groove is provided with a second guide slope 7, which is angled to the insertion direction Z. During insertion, the second guide slope 7 is adapted to cooperate with the first guide portion 4 to guide the first cylindrical portion 3021 to rotate about the insertion direction Z. That is, for example, see Figures 1 to 3 In some embodiments, the second guide portion 5 may be a second protrusion. The second protrusion may be disposed 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 it may be disposed on the outer wall of the first cylindrical portion 3021. The second protrusion is provided with a second guide slope 7 to facilitate cooperation with the first guide slope 6.

[0115] In other embodiments, the second guide portion 5 can be a second groove. The second groove can be disposed 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 it can be disposed on the outer wall of the second cylindrical portion 2021. The second groove is provided with a second guide slope 7 to facilitate cooperation with the first guide slope 6. In this disclosure, regardless of whether the second guide portion 5 is constructed as a second protrusion or a second groove, during the insertion and engagement of the first connector 201 and the second connector 301, the second guide slope 7 can cooperate with the first guide portion 4, thereby converting the movement of the first cylindrical portion 3021 along the insertion direction Z into a spiral movement that rotates while approaching the first mounting member 202. This reduces the impact force when the first connector 201 and the second connector 301 are inserted and engaged during the process of guiding the first connecting structure 2 and the second connecting structure 3 to the predetermined insertion and engagement position.

[0116] To reduce the impact force on the first guide section 4 and the second guide ramp 7, and to facilitate their cooperation, optionally, as follows: Figure 3As shown, the front end 8 of the second guide slope 7 is constructed as an arc-shaped surface. The front end 8 is the end of the second guide slope 7 that first contacts the first guide portion 4 during the insertion process. That is, during the contact between the first guide portion 4 and the second guide portion 5, the arc-shaped front end 8 can first contact the first guide portion 4 (such as the first guide slope 6 of the first guide portion 4), which can buffer the impact force from the first guide portion 4, reducing the damage to the first guide portion 4 and the second guide slope 7, while also facilitating the cooperation between the second guide slope 7 and the first guide slope 6.

[0117] To improve the impact resistance of the second protrusion, optionally, such as Figure 3 As shown, the second protrusion has a first end opposite to it in the insertion direction Z (e.g., Figure 3 The upper end shown) and the second end (as shown) Figure 3 The cross-sectional area of ​​the second end (shown as the lower end) is larger than that of the first end. The first end is the end that first contacts the first guide portion 4 during the insertion process. As an exemplary embodiment, the cross-sectional area of ​​the second protrusion gradually increases from the first end to the second end. The smaller cross-sectional area of ​​the first end compared to the second end facilitates the formation of the aforementioned second guide slope 7, which helps guide the first mounting member 202 (such as the first guide portion 4 of the first mounting member 202) when the second protrusion mates with the first guide portion 4. Furthermore, the aforementioned structure, smaller at the top and larger at the bottom, helps ensure the reliability of the second protrusion under impact.

[0118] In order for the second guide slope 7 to quickly engage with the first guide portion 4 when the first connector 201 and the second connector 301 are inserted and mated, optionally, as follows: Figure 5 As shown, there are multiple second protrusions, which are arranged at intervals along the circumference of the first cylindrical portion 3021.

[0119] Optionally, the number of second protrusions is the same as the number of first guide portions 4, and each second protrusion is adapted to mate with a corresponding first guide portion 4. In this disclosure, based on the above-mentioned arrangement of the first guide portion 4 as a first protrusion, that is, the number of second protrusions can be the same as the number of first protrusions, and each second protrusion is adapted to mate with a corresponding first protrusion. During the insertion and engagement of the first connector 201 and the second connector 301, the first guide slope 6 of the first protrusion contacts the second guide slope 7 of the second protrusion, causing the first cylindrical portion 3021 to move spirally toward the second cylindrical portion 2021 under the action of the cooperation of the first guide slope 6 and the second guide slope 7, so as to reduce the impact force when the first connector 201 and the second connector 301 are inserted and engaged. Providing multiple first protrusions and multiple second protrusions can improve the reliability of guiding the rotation of the first cylindrical portion 3021.

[0120] like Figures 5 to 8As shown in this disclosure, the second mounting member 302 may further include a limiting component 3023, which is used to axially limit the first cylindrical portion 3021 on the mounting base 3022 so that the first cylindrical portion 3021 can rotate relative to the mounting base 3022 but will not detach from the mounting base 3022.

[0121] This disclosure does not limit the specific structure of the limiting component 3023, but provides an exemplary implementation, such as Figures 5 to 8 As shown, the limiting component 3023 includes a limiting groove 30231 and a limiting protrusion 30232. The limiting protrusion 30232 is disposed on one of the second stop surface 1102 and the second side wall 1202, and the limiting groove 30231 is disposed on the other of the second stop surface 1102 and the second side wall 1202. The limiting protrusion 30232 and the limiting groove 30231 are inserted into each other.

[0122] For example, see Figure 7 and Figure 8 The limiting protrusion 30232 can be disposed on the second stop surface 1102 and can extend within the slide groove 10 along the extending direction of the slide groove 10; the limiting groove 30231 can be disposed on the second side wall 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 base 3022, one end of the first cylindrical portion 3021 connected to the mounting base 3022 is engaged in the slide groove 10, the first side wall 1201 of the recess 12 abuts against one end of the elastic member 9, and engages the elastic member 9 in the slide groove 10 located between the recess 12 and the stop portion 11, and the second side wall 1202 of the recess 12 is engaged with the limiting protrusion 30232 on the second stop surface 1102 through the limiting groove 30231, thereby achieving axial limiting of the first cylindrical portion 3021.

[0123] It is understandable that when the first sidewall 1201 of the aforementioned recess 12 abuts against one end of the elastic member 9, the elastic member 9 can be in a free state, and the second sidewall 1202 of the recess 12 can be inserted and engaged with the limiting protrusion 30232 on the second stop surface 1102 through the limiting groove 30231; 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 engagement length to accommodate the deformation of the elastic member 9. That is to say, 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. The limiting protrusion 30232 is always inserted in the limiting groove 30231 and will not affect the insertion and engagement of the first connecting member 201 and the second connecting member 301.

[0124] In this disclosure, considering that module 1 can be mass-produced, the position of the first connecting structure 2 on one module 1 can be preset, and the position of the second connecting structure 3 on another module 1 can also be preset. Generally, in the process of connecting two module 1s, it is only necessary to align the two module 1s to achieve the insertion of the first connecting structure 2 and the second connecting structure 3. However, due to factors such as processing errors, there may be deviations between the position of the first connecting structure 2 on one module 1 and the preset position, or between the position of the second connecting structure 3 on another module 1 and the preset position, which will increase the difficulty of aligning the first connecting structure 2 and the second connecting structure 3.

[0125] In this disclosure, in order to improve the accuracy of the insertion of the first connecting structure 2 and the second connecting structure 3, and to reduce the probability of wear on the first connecting structure 2 and the second connecting structure 3 during the insertion process, thereby achieving a flexible connection between the first connecting structure 2 and the second connecting structure 3, optionally, as follows: Figure 1 As shown, at least one of the first connecting structure 2 and the second connecting structure 3 is adapted to be movably connected to the corresponding module 1 in the first direction X, thereby guiding the first connecting structure 2 and the second connecting structure 3 to a predetermined mating position. The first direction X intersects with the mating direction Z of the first connecting structure 2 and the second connecting structure 3. With this configuration, during the mating process of the first connecting structure 2 and the second connecting structure 3, the movement of one or both of the first connecting structure 2 and the second connecting structure 3 in the first direction X can eliminate processing errors and facilitate alignment of the first connecting structure 2 and the second connecting structure 3, thereby improving the accuracy of the mating. As an exemplary embodiment, the first direction X is perpendicular to the mating direction Z of the first connecting structure 2 and the second connecting structure 3 to enhance the flexible connection effect of the first connecting structure 2 and the second connecting structure 3.

[0126] To further improve the accuracy of the insertion of the first connecting structure 2 and the second connecting structure 3, and to reduce the probability of wear on the first connecting structure 2 and the second connecting structure 3 during the insertion process, optionally, as follows: Figure 1As shown, at least one of the first connecting structure 2 and the second connecting structure 3 is adapted to be movably connected to the corresponding module 1 in the second direction Y. The second direction Y intersects the first direction X, and both the second direction Y and the first direction X are located in a plane perpendicular to the insertion 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 along the first direction X or the second direction Y in a plane perpendicular to the insertion direction Z to further eliminate processing errors and improve the accuracy of the docking of the first connecting structure 2 and the second connecting structure 3. As an exemplary embodiment, the first direction X and the second direction Y are orthogonal.

[0127] Based on the electrical connection of the two modules 1 and the specific structure of the second connection structure 3, optionally, as follows: Figure 5 As shown, the first cylindrical portion 3021 is movably connected to the mounting base 3022 in the first direction X, which intersects with the insertion direction Z. The movement of the first cylindrical portion 3021 in the first direction X facilitates the insertion and engagement of the second connector 301 with the first connecting structure 2, thereby improving the accuracy of the insertion between the second connector 301 and the first connecting structure 2.

[0128] Optionally, such as Figure 5As shown, the mounting base 3022 includes a first mounting block 30221 and at least two second mounting blocks 30222. A first cylindrical portion 3021 is connected to the first mounting block 30221, and a second connecting member 301 is fixed to the first mounting block 30221. For example, the second connecting member 301 passes through and is fixedly limited in a limiting through hole on the first mounting block 30221, so that the second connecting member 301 can move with the first mounting block 30221 (as described below, moving in the first direction X and the second direction Y). The second mounting blocks 30222 are adapted to be installed onto the corresponding module 1. The two second mounting blocks 30222 are arranged at intervals along the first direction X. Each second mounting block 30222 has a stepped portion 13 on the side opposite to the first connecting structure 2. There is an accommodating space 14 between the two stepped portions 13. The length of the accommodating space 14 in the first direction X is greater than the length of the first mounting block 30221 in the first direction X. Therefore, the first mounting block 30221 can be accommodated within the accommodating space 14 between the two stepped portions 13. This prevents the first mounting block 30221 from disengaging from the accommodating space 14 along the insertion direction Z, and allows it to move within the accommodating space 14 along the first direction X, thus eliminating machining errors in 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 outside the corresponding module 1, and this disclosure does not limit the fixing method of the second mounting block 30222 outside the module 1. As an exemplary embodiment, the second mounting block 30222 can be fixed to the outside of the module 1 by bolts.

[0129] To facilitate the formation of the aforementioned accommodating space 14, optionally, as follows: Figure 1 As shown, the module 1 is provided with a cavity 15 for mounting the first connecting structure 2 or the second connecting structure 3. The second mounting block 30222 can be installed in the cavity 15 on the module 1. The two stepped portions 13 and the inner wall of the cavity 15 together define an accommodating space 14. The length of the accommodating space 14 in the second direction Y is greater than the length of the first mounting block 30221 in the second direction Y. Furthermore, the second direction Y and the first direction X are both located in a plane perpendicular to the insertion direction Z. That is to say, after the first mounting block 30221 is accommodated in the accommodating space 14, the first mounting block 30221 can move along the first direction X or the second direction Y within the accommodating space 14 to eliminate processing errors. The accommodating space 14 can also limit the length of movement of the first mounting block 30221 along the first direction X or the second direction Y, which can prevent the first mounting block 30221 from leaving the accommodating space 14 along the first direction X or the second direction Y.

[0130] In this disclosure, the first connecting structure 2 described above can be disposed on one module 1 to form a module assembly, and the second connecting structure 3 described above can be disposed on another module 1 to form another module assembly. During installation, the two module assemblies described above can be assembled to form the following modular device.

[0131] According to a second aspect of this disclosure, a module device is provided, the module device including the above-described connection structure and a plurality of module components 1, wherein at least two adjacent module components 1 are connected by the connection structure, and at least one of the first connection structure 2 and the second connection structure 3 is movably disposed on the corresponding module component 1.

[0132] In this disclosure, as an exemplary embodiment, the module device can be an energy storage device, and the module 1 can be a battery module. Any two adjacent module 1s among the plurality of module 1s are electrically connected through a connection structure. That is, the electrical connection of the multiple module 1s is achieved through the connection structure to form an energy storage cabinet capable of supplying power to the outside, such as a power cabinet or a battery pack.

[0133] To facilitate electrical connection between multiple module components 1, optionally, one of any two adjacent module components 1 connected by a connection structure is provided with a first through hole, and the other is provided with a second through hole. The first connection structure 2 includes a first connector 201, which passes through the first through hole and is electrically connected to the electrical components inside the corresponding module component 1. The second connection structure 3 includes a second connector 301, which passes through the second through hole and is electrically connected to the electrical components inside the corresponding module component 1. With this configuration, the electrical components inside the module component 1 corresponding to the first connector 201 are electrically connected to the module component 1 corresponding to the second connector 301 through the insertion and engagement of the first connector 201 and the second connector 301. Here, the aforementioned second cylindrical portion 2021 is provided with a first through hole communicating with the first through hole, so that the first connector 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 1; the aforementioned first cylindrical portion 3021 is provided with a second through hole and the first mounting block 30221 is provided with a third through hole, the second through hole and the third through hole are interconnected, so that the second connector 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 1.

[0134] The preferred embodiments of this disclosure have been described in detail above with reference to the accompanying drawings. However, this disclosure is not limited to the specific details of the above embodiments. Within the scope of the technical concept of this disclosure, various simple modifications can be made to the technical solutions of this disclosure, and these simple modifications all fall within the protection scope of this disclosure.

[0135] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, this disclosure will not describe the various possible combinations separately.

[0136] Furthermore, various different embodiments of this disclosure can be combined in any way, as long as they do not violate the spirit of this disclosure, they should also be regarded as the content disclosed in this disclosure.
