[0050] The following describes in detail embodiments of the present application. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application and are not to be construed as limiting the present application.

[0051] In the description of the present application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0052] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. Throughout the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0053] In this application, unless otherwise expressly specified or limited, terms such as "mounted," "connected," "connect," and "fixed" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components or interactions between two components. Those skilled in the art will understand the specific meanings of these terms in this application based on specific circumstances.

[0054] In this application, unless otherwise expressly specified or limited, when a first feature is "above" or "below" a second feature, it may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Furthermore, when a first feature is "above," "above," or "above" a second feature, it may mean that the first feature is directly above or diagonally above the second feature, or simply means that the first feature is at a higher level than the second feature. When a first feature is "below," "below," or "below" a second feature, it may mean that the first feature is directly below or diagonally below the second feature, or simply means that the first feature is at a lower level than the second feature.

[0055] like Figure 1 、 Figure 2 and Figure 6 As shown, an embodiment of the present application provides a docking mechanism 100, including a bus assembly 110 and a docking assembly 120. The docking assembly 120 is connected to the bus assembly 110 for power connection.

[0056] A power connection is the physical and electrical connection between the power source and the load in an electronic device or system.

[0057] The busbar assembly 110 includes a positive busbar 111 a , a negative busbar 111 b , an insulating member 112 , and a follower 114 .

[0058] The positive bus bar 111 a and the negative bus bar 111 b are spaced apart from each other and are connected to the insulating member 112 to prevent short circuit.

[0059] In related art, the busbar assembly is fixed as a whole, for example, in a photovoltaic combiner box for photovoltaic power generation, while the docking assembly, which forms an electrical connection with the busbar assembly, is installed on a mobile energy storage vehicle. A moving mechanism within the mobile energy storage vehicle drives the docking assembly toward the busbar assembly, establishing an electrical connection between the two.

[0060] Since the docking assembly is driven by a transfer mechanism, it has few degrees of freedom and poor flexibility. When the bus assembly is fixed, the bus assembly has poor flexibility, and the alignment accuracy between the positive bus or negative bus and the docking assembly is reduced, resulting in the connection between the bus assembly and the docking assembly being not strong enough or even falling off.

[0061] In response to the above problems, a movable groove 11211 is provided on the insulating part 112, and the follower 114 includes a base 1141 and a connecting rod 1144. It should be understood that the base 1141 of the follower 114 is fixedly arranged, and the base 1141 is spaced apart from the insulating part 112. The connecting rod 1144 is passed through the movable groove 11211, so that the base 1141 provides support force to the insulating part 112 through the connecting rod 1144. The connecting rod 1144 is also rotatably connected to the base 1141 so that the connecting rod 1144 moves in the movable groove 11211 to adjust the positions of the insulating part 112, the positive bus 111a and the negative bus 111b, so that the bus assembly 110 is more flexible, the alignment accuracy of the bus assembly 110 and the docking assembly 120 is improved, and the connection stability between the bus assembly 110 and the docking assembly 120 is enhanced.

[0062] It should be noted that the docking mechanism 100 has a first direction D1 , a second direction D2 and a third direction D3 .

[0063] The first direction D1 is parallel to the plugging and unplugging direction of the power connection terminal 121, the second direction D2 is the spacing distribution direction of the positive busbar 111a and the negative busbar 111b, and the third direction D3 is the length direction of the positive busbar 111a. The first direction D1, the second direction D2 and the third direction D3 are perpendicular to each other. For example, the first direction D1 is Figure 1 The up and down direction in the second direction D2 is Figure 1The left and right directions and the third direction D3 are Figure 1 In the front-to-back direction, in other drawings, the first direction D1, the second direction D2 and the third direction D3 can be adaptively adjusted.

[0064] like Figures 1 to 3 As shown, in some embodiments, the movable slot 11211 penetrates the insulating member 112 along the first direction D1 , extends along the second direction D2 , and the connecting rod 1144 is disposed in the movable slot 11211 along the first direction D1 .

[0065] In some embodiments, the movable slot 11211 is an oblong hole arranged along the second direction D2.

[0066] It should be understood that base 1141 is fixed, while connecting rod 1144 is movably disposed within movable slot 11211. When docking assembly 120 and busbar assembly 110 are docked, due to the offset between docking assembly 120 and busbar assembly 110, docking assembly 120 drives insulating member 112, positive busbar 111a, and negative busbar 111b to move. At this point, between connecting rod 1144 and insulating member 112, connecting rod 1144 remains stationary, while insulating member 112 is able to translate along second direction D2.

[0067] like Figures 1 to 3 As shown, in some embodiments, in the third direction D3, the outer diameter of the connecting rod 1144 is smaller than the size of the movable groove 11211. When the docking assembly 120 and the busbar assembly 110 are docked, due to the offset between the docking assembly 120 and the busbar assembly 110, the docking assembly 120 drives the insulator 112, the positive busbar 111a, and the negative busbar 111b to move. At this time, between the connecting rod 1144 and the insulator 112, the connecting rod 1144 remains stationary, while the insulator 112 can translate along the third direction D3.

[0068] like Figures 1 to 3 As shown, in some embodiments, follower 114 further includes a stopper 1145. Stopper 1145 is disposed on a side of insulating member 112 away from base 1141 and connected to connecting rod 1144. In first direction D1, stopper 1145 is spaced apart from insulating member 112. When docking assembly 120 and bus assembly 110 are docked, due to the offset between docking assembly 120 and bus assembly 110, docking assembly 120 drives insulating member 112, positive bus 111a, and negative bus 111b to move. At this point, between connecting rod 1144 and insulating member 112, connecting rod 1144 remains stationary, while insulating member 112 is able to translate along first direction D1.

[0069] It can be understood that the base 1141 is fixedly connected to the wall panel of the power distribution cabinet, so that the follower 114 is fixed to the wall panel, and the insulating member 112 is connected to the wall panel through the follower 114. The limit block 1145 is provided to prevent the insulating member 112 from falling off the connecting rod 1144, and the follower 114 supports the insulating member 112.

[0070] like Figures 1 to 3 As shown, in some embodiments, the base 1141 and the insulating member 112 are spaced apart along the first direction D1, and a groove 11411 is formed on the base 1141. The opening of the groove 11411 faces the insulating member 112, and the communication direction of the opening of the groove 11411 is also parallel to the second direction D2.

[0071] The follower 114 also includes a movable seat 1142 and a pin shaft 1143. The connecting rod 1144 is connected to the movable seat 1142. The movable seat 1142 includes a mosaic block 11421 arranged in the groove 11411. The base 1141 and the mosaic block 11421 are provided with overlapping holes 11412 arranged along the third direction D3. The pin shaft 1143 is passed through the overlapping hole 11412, so that the movable seat 1142 is hinged to the base 1141.

[0072] In this way, Figure 1 As described above, the engaging block 11421 uses the pin shaft 1143 as the rotation axis 1442 and the connecting rod 1144 as the swing rod, and swings in a plane perpendicular to the third direction D3.

[0073] It should be noted that, as previously described, the insulating member 112 is capable of translating relative to the connecting rod 1144 in the first direction D1, the second direction D2, and the third direction D3. In other words, the connecting rod 1144 is capable of moving relative to the movable groove 11211 in the first direction D1, the second direction D2, and the third direction D3. When the docking assembly 120 and the busbar assembly 110 are docked, the connecting rod 1144 can also swing within planes perpendicular to the first direction D1 and the second direction D2, using the contact point between the connecting rod 1144 and the wall of the movable groove 11211 as a fulcrum and the connecting rod 1144 as a swinging lever.

[0074] like Figure 3 As shown, in some embodiments, the insulating member 112 includes a fixing plate 1121 and a plurality of insulating blocks 1122 .

[0075] The positive bus bar 111 a and the negative bus bar 111 b are respectively spaced apart from the fixing plate 1121 , and the movable slot 11211 is defined in the fixing plate 1121 .

[0076] In some embodiments, the cross-section of the fixed plate 1121 is U-shaped, and the fixed plate 1121 includes a middle portion 11213 and two side portions 11212. The follower 114 is connected to the middle portion 11213 of the fixed plate 1121 and is disposed on the side away from the opening of the fixed plate 1121; the insulating block 1122 is connected to the side portion 11212 of the fixed plate 1121 and is disposed on the side away from the opening of the fixed plate 1121.

[0077] It can be understood that the U-shaped fixing plate 1121 can reduce the mass and make the cooperation between the follower 114 and the fixing plate 1121 more flexible.

[0078] The fixing plate 1121 is made of any one of plastic, metal, and ceramic.

[0079] When the fixing plate 1121 is made of plastic, the fixing plate 1121 can play the role of insulation and weight reduction.

[0080] In this embodiment, there are three followers 114 spaced apart along the third direction D3. There are two movable slots 11211 disposed at the ends of the positive busbar 111a or the negative busbar 111b along the third direction D3.

[0081] Among the three followers 114 , the middle follower 114 is not provided with a pin 1143 and supports the fixed plate 1121 . The remaining two followers 114 can move along with the fixed plate 1121 .

[0082] In other embodiments, the number of the followers 114 may be one, two, four, etc. The number of the followers 114 may be set according to actual needs.

[0083] The insulating block 1122 connects the positive bus bar 111 a and the fixing plate 1121 , and the negative bus bar 111 b and the fixing plate 1121 , so as to form an insulating connection between the positive bus bar 111 a and the negative bus bar 111 b and the fixing plate 1121 respectively, thereby preventing short circuit.

[0084] In this embodiment, the insulating blocks 1122 are block-shaped and there are six of them, three of which are connected to one side 11212 of the U-shaped fixing plate 1121 , and the remaining three insulating blocks 1122 are connected to the other side 11212 of the U-shaped fixing plate 1121 .

[0085] The three insulating blocks 1122 connected to the same side 11212 are spaced apart along the length direction of the positive busbar 111a. The insulating blocks 1122 are arranged between the positive busbar 111a and the fixed plate 1121, and between the negative busbar 111b and the fixed plate 1121, so that the positive busbar 111a and the negative busbar 111b are spaced apart from the fixed plate 1121 respectively, reserving space for the subsequent setting of the guide member 113.

[0086] In other embodiments, the shape of the insulating block 1122 may also be a long strip, and the number of the insulating blocks 1122 may be selected according to actual needs.

[0087] like Figure 4 As shown, in some embodiments, the docking mechanism 100 further includes an end cover 130 and two opening and closing assemblies 140 .

[0088] As mentioned above, the busbar assembly 110 is usually housed in a cabinet, and the end cover 130 is connected to the cabinet.

[0089] The end cap 130 is spaced apart and disposed on a side of the insulating member 112 away from the base 1141 .

[0090] The end cover 130 is in a plate shape.

[0091] The end cover 130 is provided with two windows 131 spaced apart from each other.

[0092] In this embodiment, there are two windows 131 , one of which is provided corresponding to the positive electrode current bus 111 a , and the other window 131 is provided corresponding to the negative electrode current bus 111 b .

[0093] An opening and closing assembly 140 is disposed corresponding to a window 131 , and the opening and closing assembly 140 is connected to a side of the end cover 130 close to the insulating member 112 .

[0094] In some embodiments, the opening and closing assembly 140 includes a driving member 141 , a shielding member 142 and a transmission member 143 .

[0095] The driving member 141 is a pneumatic cylinder or a hydraulic cylinder, and has a telescopic rod 1411 that telescopes along the third direction D3.

[0096] The shielding member 142 includes a cover plate 1421 and a first locking block 1422 . The cover plate 1421 is rotatably connected to the end cover 130 to open or close the window 131 .

[0097] In some embodiments, the cover 1421 is made of transparent plastic to reduce weight and facilitate users to observe the interior of the cabinet through the cover 1421.

[0098] The output end of the driving member 141 is connected to the transmission member 143 , and the transmission member 143 is disposed between the two windows 131 .

[0099] The first locking block 1422 is disposed on a side of the cover plate 1421 close to the transmission member 143 .

[0100] like Figure 4 As shown, the transmission member 143 is provided with two second locking blocks 1431 spaced apart along the second direction D2. The driving member 141 drives the second locking block 1431 to move toward or away from the first locking block 1422, so that the first locking block 1422 and the second locking block 1431 are locked or separated.

[0101] In some embodiments, as Figure 4 As shown, the transmission member 143 further includes a movable frame 1432 , and the movable frame 1432 includes four movable rods, which are sequentially connected end to end to form a quadrilateral structure.

[0102] The diagonal line of the movable frame 1432 is parallel to the second direction D2 or the third direction D3, so that one corner of the movable frame 1432 is close to one cover plate 1421, the corner of another movable frame 1432 is close to the other cover plate 1421, and the corner of another movable frame 1432 is connected to the telescopic rod 1411 of the driving member 141.

[0103] Two adjacent movable rods are hinged, so that the movable frame 1432 is deformed under the drive of the driving member 141 , and the driving member 141 drives the two diagonals of the movable frame 1432 arranged along the second direction D2 to move toward or away from each other.

[0104] For example, when the telescopic rod 1411 of the driving member 141 retracts, the second locking block 1431 and the first locking block 1422 separate from each other, and the opening and closing assembly 140 is in an unlocked state; when the telescopic rod 1411 of the driving member 141 extends, the second locking block 1431 and the first locking block 1422 approach each other to lock, and the opening and closing assembly 140 is in a locked state.

[0105] like Figure 4 As shown, in some embodiments, the transmission member 143 further includes a slide rail disposed between the two windows 131. Figure 9 As shown, the slide rail is cross-shaped and has four sliding tracks corresponding to the four corners of the quadrilateral movable frame 1432. The movable frame 1432 slides on the slide rails to achieve deformation.

[0106] In some embodiments, the first locking block 1422 and the second locking block 1431 are locked together by magnetic attraction or mechanical snap connection.

[0107] It is understood that in some embodiments, the window 131 may be locked or unlocked by changing the positions of the movable frame 1432 , the first locking block 1422 , and the second locking block 1431 .

[0108] For example, the first locking block 1422 is set on the side of the cover 1421 close to the driving member 141, the movable frame 1432 is a U-shaped structure, and the second locking block 1431 is set at the end of the U-shaped movable frame 1432. The driving member 141 drives the telescopic rod 1411 to drive the movable frame 1432 to move toward or away from the cover 1421, so that the first locking block 1422 and the second locking block 1431 are locked or separated.

[0109] like Figure 4 As shown, in some embodiments, the opening and closing assembly 140 further includes a restoring member 144 .

[0110] The reset member 144 is used to cover the window 131 when the power plug terminal leaves the window 131, so that the cover plate 1421 covers the window 131, so that the bus assembly 110 and the opening and closing assembly 140 are enclosed in a cabinet such as a distribution cabinet for protection.

[0111] The reset member 144 is connected to a side of the cover plate 1421 away from the first locking block 1422 , and the reset member 144 is elastic. In one embodiment, the reset member 144 is a spring 1441 .

[0112] The cover plate 1421 is provided with a rotating shaft 1442, and the rotating shaft 1442 rotates to drive the cover plate 1421 to rotate to open or close the window 131. One end of the rotating shaft 1442 is rotatably connected to the end cover 130, and the other end is fixedly connected to the cover plate 1421.

[0113] like Figure 4 As shown, the spring 1441 drives the rotating shaft 1442 to rotate in the direction of closing the window 131.

[0114] One end of spring 1441 is fixedly connected to end cap 130, and the other end is fixedly connected to cover plate 1421. When cover plate 1421 is opened, spring 1441 is in a compressed or stretched state. When power connection terminal 121 is removed, spring 1441 returns to its original position, causing shaft 1442 to rotate, driving cover plate 1421 to cover window 131.

[0115] It is understandable that the spring 1441 can also be replaced by a spring sheet or a spring block.

[0116] In some embodiments, as Figures 4 to 6 As shown, by arranging the rotating shaft 1442 above the cover plate 1421 , the spring 1441 may not be provided, and gravity may be used to cause the cover plate 1421 to fall and cover the window 131 .

[0117] In some embodiments, the number of the positive electrode bus bar 111 a is at least one, and the number of the negative electrode bus bar 111 b is at least one.

[0118] At least one positive electrode bus bar 111 a and at least one negative electrode bus bar 111 b are spaced apart and respectively connected to the insulating member 112 to prevent short circuit.

[0119] like Figure 5 As shown, the positive electrode bus bar 111 a and the negative electrode bus bar 111 b are spaced apart from each other along the second direction D2 .

[0120] At least one first plug-in portion 1111 is provided on each of the positive bus bar 111 a and the negative bus bar 111 b .

[0121] It should be noted that if Figure 3 、 Figure 5 and Figure 6 As shown, in this embodiment, the number of the positive electrode bus bar 111a and the number of the negative electrode bus bar 111b are both one. In other embodiments, the number of the positive electrode bus bar 111a and the number of the negative electrode bus bar 111b can be set as required.

[0122] For example, in Figure 3 In the figure, the positive busbar 111a on the left is split into three sections of positive busbars 111a, and a first plug-in portion 1111 is provided on each section of the positive busbar 111a; correspondingly, the negative busbar 111b on the right is split into three sections of negative busbars 111b, and a first plug-in portion 1111 is provided on each section of the negative busbar 111b.

[0123] In this embodiment, if Figure 3 As shown, the positive busbar 111a and the negative busbar 111b are both in the shape of long plates, the plate surfaces of the positive busbar 111a and the negative busbar 111b are arranged relative to each other, the first plug-in portion 1111 is arranged on the side of the positive busbar 111a and the negative busbar 111b, and the first plug-in portion 1111 of the positive busbar 111a and the first plug-in portion 1111 of the negative busbar 111b are arranged side by side.

[0124] The docking assembly 120 includes multiple power connection terminals 121, and the power connection terminal 121 is provided with a second plug-in portion 1211. A first plug-in portion 1111 corresponds to a second plug-in portion 1211 for electrically connecting the power connection terminal 121 with the positive busbar 111a or the negative busbar 111b, so that the power connection between the docking assembly 120 and the busbar assembly 110 is tighter and more secure.

[0125] In this embodiment, if Figure 3 、 Figure 5 and Figure 6As shown, the first plug-in portion 1111 is located on the side of the positive busbar 111a and the negative busbar 111b. The first plug-in portion 1111 is flat and integrally provided with the busbar 111. The second plug-in portion 1211 is a notch formed on the power connection terminal 121. The cross-section of the second plug-in portion 1211 is strip-shaped, which facilitates the clamping of the power connection terminal 121 on the busbar 111, so that the positive busbar 111a and the power connection terminal 121, and the negative busbar 111b and the power connection terminal 121 are electrically connected through plugging and unplugging.

[0126] It should be understood that in some embodiments, the matching shapes of the flat first plug portion 1111 and the second plug portion 1211 with a strip-shaped notch in cross section can vary. For example, the second plug portion 1211 of the power connection terminal 121 is cylindrical, and the first plug portion 1111 is correspondingly cylindrical, so that the two shapes match and the connection is more stable.

[0127] In other embodiments, the first plug-in portion 1111 can also be provided on the power connection terminal 121, and the second plug-in portion 1211 can be provided on the positive busbar 111a and the negative busbar 111b, so that a notch is formed on the positive busbar 111a or the negative busbar 111b, and a flat plate is formed on the power connection terminal 121.

[0128] In other words, the first plug portion 1111 and the second plug portion 1211 are male and female connectors that form an electrical connection. The male connector can be provided on the positive bus bar 111a or the negative bus bar 111b, and the female connector can be provided on the power connection terminal 121. Alternatively, the female connector can be provided on the positive bus bar 111a or the negative bus bar 111b, and the male connector can be provided on the power connection terminal 121. The shape and structure of the male and female connectors can be set according to actual needs.

[0129] In other embodiments, a split first plug-in portion 1111 can be connected to the positive busbar 111a or the negative busbar 111b, and a notch, a plate-shaped or columnar structure can be formed on the first plug-in portion 1111 to connect the first plug-in portion 1111 to the second plug-in portion 1211. This makes it convenient to adjust the power connection position of the busbar assembly 110 and the docking assembly 120 according to needs.

[0130] In this embodiment, only one first plug-in portion 1111 is provided on the positive busbar 111a or the negative busbar 111b. Accordingly, there are two power connection terminals 121. One first plug-in portion 1111 is pluggable with one second plug-in portion 1211, so that one power connection terminal 121 forms an electrical connection with the positive busbar 111a or the negative busbar 111b.

[0131] When there are multiple first plugging portions 1111 on the positive busbar 111a or the negative busbar 111b, the number of the power connection terminals 121 is the same as the total number of the first plugging portions 1111 on the positive busbar 111a and the negative busbar 111b.

[0132] Multiple first plug-in connectors 1111 are spaced apart along the length of the positive busbar 111a or the negative busbar 111b, and each first plug-in connector 1111 is pluggable with each second plug-in connector 1211. This increases the number of power connection points between the busbar assembly 110 and the docking assembly 120, making the power connection between the docking assembly 120 and the busbar assembly 110 tighter and more secure, while also improving power transmission efficiency.

[0133] Accordingly, there are at least two windows 131 . For example, the number of windows 131 is the same as the total number of first plugging portions 1111 , so that one window 131 is corresponding to one first plugging portion 1111 , and one power connection terminal 121 is correspondingly disposed in one window 131 .

[0134] The housing 1213 of a power connection terminal 121 is inserted into a window 131 , so that the plug connector 1212 enters the inner side of the end cover 130 and is plugged into the first plug portion 1111 .

[0135] like Figure 9 As shown, the docking assembly 120 further includes a terminal fixing seat 122, and two power connection terminals 121 are spaced apart and arranged on the terminal fixing seat 122. The docking assembly 120 can be arranged on various mobile devices, such as a mobile energy storage vehicle.

[0136] The docking assembly 120 is pushed outward by a moving mechanism in the new energy vehicle, so that the power connection terminal 121 is moved closer to the bus assembly 110 .

[0137] During the docking process between the docking assembly and the bus assembly, the angle of the vehicle body is improper, causing the second plug-in parts of the two power connection terminals extending out of the vehicle body to be deflected and uneven relative to the first plug-in parts of the bus assembly.

[0138] The above situation causes the second plug-in portion of the power connection terminal to deviate from the first plug-in portion of the busbar assembly, making it impossible to align them. If the busbar assembly is fixed in position, after the plug-in is completed, there is a situation where one power connection terminal is fully connected to the busbar, while the other power connection terminal is not fully connected to the other busbar;

[0139] Alternatively, there may be a case where one of the power connection terminals can be connected to the first plug-in portion of the busbar, while the other power connection terminal cannot be connected to the first plug-in portion of the busbar.

[0140] To address the above problem, the connecting rod 1144 moves in the movable groove 11211, so that during the plugging and unplugging process of the second plug-in portion 1211 of the power connection terminal 121 and the first plug-in portion 1111 of the bus 111, the follower 114 provides freedom of movement for the insulating member 112, the positive bus 111a and the negative bus 111b as a whole, so that the movement of the power connection terminal 121 drives the insulating member 112, the positive bus 111a and the negative bus 111b to move as a whole, so that the second plug-in portion 1211 and the first plug-in portion 1111 are aligned and fully plugged in, thereby forming a tight and stable connection.

[0141] When the power connection terminal 121 is connected to the positive bus bar 111a or the negative bus bar 111b, the power connection terminal 121 drives the insulating member 112 to move, so that the insulating member 112 translates relative to the connecting rod 1144 along the first direction D1, the second direction D2 or the third direction D3, or swings relative to the connecting rod 1144 in a plane perpendicular to the first direction D1, the second direction D2 or the third direction D3, so that the first plug-in portion 1111 is aligned with the second plug-in portion 1211.

[0142] For example, when the two power connection terminals 121 are misaligned in the first direction D1, so that one of the power connection terminals 121 is closer to one of the busbars, if the busbar cannot move, the power connection terminal 121 closer to the busbar can form a tight connection with the busbar, while the other power connection terminal 121 cannot form a tight connection with the other busbar.

[0143] In view of the above situation, if Figure 2 and Figure 3 As shown, when the two power connection terminals 121 are connected to the positive bus bar 111a and the negative bus bar 111b, due to the different insertion forces between the two power connection terminals 121 and the bus bars, the two power connection terminals 121 apply a torque to the insulating member 112. Since the follower 114 is provided, the connecting rod 1144 connected to the insulating member 112 drives the movable seat 1142 to swing, so that the insulating member 112 can rotate in a plane perpendicular to the third direction D3 under the action of the torque.

[0144] Such rotation reduces the distance between the other power connection terminal 121 and the busbar, so that each power connection terminal 121 is aligned with the first plug-in portion 1111 of the corresponding busbar, and the plug-in depth of each power connection terminal 121 and the busbar is consistent, and both power connection terminals 121 form a stable connection.

[0145] Similarly, if Figure 2 and Figure 3As shown, when the two power connection terminals 121 are not aligned in the third direction D3, the torque applied by the two power connection terminals 121 to the insulating member 112 drives the insulating member 112 to rotate in a plane perpendicular to the first direction D1, so that each power connection terminal 121 is aligned with the first plug-in portion 1111 of the corresponding bus 111, and the two power connection terminals 121 form a stable connection.

[0146] Typically, the distance between the second plug-in portions 1211 of the two power connection terminals 121 is equal to the distance between the first plug-in portions 1111 of the two busbars. During actual docking, the two power connection terminals 121 and the two busbars may be misaligned in the second direction D2. In this case, if a power connection terminal 121 is docked with a busbar that cannot move, docking may fail, or the power connection terminal 121 or the busbar may become deformed.

[0147] In response to the above problems, Figures 2 to 4 As shown, the insulating member 112 can move relative to the connecting rod 1144 along the second direction D2.

[0148] Thus, during the plugging process, the power connection terminal 121 drives the two busbars to move, and by providing the movable slot 11211, the insulating member 112 can translate relative to the connecting rod 1144 along the second direction D2. Each power connection terminal 121 is aligned with the first plug portion 1111 of the corresponding busbar, and both power connection terminals 121 form a stable connection.

[0149] like Figure 7 and Figure 8 As shown, in some embodiments, the bus assembly 110 further includes at least two guide members 113 , and each guide member 113 is slidably engaged with a power connection terminal 121 .

[0150] At least two guide members 113 are symmetrically arranged along the third direction D3. The guide members 113 are connected to the insulating member 112 and are arranged on a side close to the positive bus bar 111a or the negative bus bar 111b. One guide member 113 is arranged corresponding to one first plug-in portion 1111.

[0151] like Figure 8 As shown, the cross section of the guide member 113 is a right triangle, the hypotenuse of the guide member 113 faces the positive bus bar 111 a or the negative bus bar 111 b , and the right angle side is connected to the fixing plate 1121 .

[0152] In some embodiments, the guide member 113 has a guide surface 1131 facing the positive bus bar 111a or the negative bus bar 111b, and the end of the power connection terminal 121 is provided with a sliding surface 12123. When the second plug-in portion 1211 is plugged in or unplugged from the first plug-in portion 1111, the guide surface 1131 and the sliding surface 12123 are matched and connected.

[0153] like Figure 2 and Figure 8 As shown, the power connection terminal 121 includes a plug connector 1212 and a housing 1213 .

[0154] The housing 1213 is fixedly connected to the terminal fixing seat 122 , and the plug connector 1212 is disposed at an end portion of the housing 1213 such that the plug connector 1212 is exposed.

[0155] The plug connector 1212 includes a clamping end 12121 and a wire connecting end 12122. The wire connecting end 12122 is arranged in the shell 1213. The shell 1213 has a hollow structure, which allows the plug connector 1212 to be connected to an external electrical appliance through a wire, and also allows the shell 1213 to store and protect the wire.

[0156] The second plug portion 1211 is disposed on the clamping end 12121, connecting the clamping end 12121 to the first plug portion 1111. The cross section of the clamping end 12121 is generally rectangular, and the corner of the clamping end 12121 away from the wire connection end 12122 is beveled to form a sliding surface 12123 that cooperates with the guide surface 1131.

[0157] In some embodiments, the guide surface 1131 is an inclined surface, and in the direction approaching the base 1141, the distance between the guide surface 1131 and the positive bus 111a or the negative bus 111b gradually decreases, so that the guide member 113 guides the docking of the clamping end 12121 and the positive bus 111a, the clamping end 12121 and the negative bus 111b, and also assists in clamping the clamping end 12121 and the positive bus 111a, the clamping end 12121 and the negative bus 111b, so that the connection between the power connection terminal 121 and the bus assembly 110 is more secure.

[0158] It is understandable that the guide surface 1131 can also be set as an arc surface or a serrated surface, and the sliding surface 12123 is changed accordingly to correspond to the guide surface 1131.

[0159] The present application also provides a docking device, comprising the docking mechanism 100 in any of the above embodiments, an energy storage mechanism (not shown) and a moving mechanism (not shown).

[0160] The energy storage mechanism is electrically connected to the positive busbar 111 a and the negative busbar 111 b respectively, and the moving mechanism is connected to the docking assembly 120 . The moving mechanism drives the power connection terminal 121 to move toward or away from the busbar assembly 110 .

[0161] In some embodiments, the docking device also includes a power management module (not shown) and a control module (not shown). The power management module is connected to the energy storage mechanism and the driving member 141, and the control module is connected to the moving mechanism, so that the energy storage mechanism, the driving member 141 and the moving mechanism can work according to the electronic control instructions.

[0162] The working process of the docking device is as follows:

[0163] After the power management module and the control module communicate and confirm that both are ready, the driver 141 drives the telescopic rod 1411 to retract, and the quadrilateral movable frame 1432 deforms, separating the first locking block 1422 and the second locking block 1431, thus completing the unlocking.

[0164] The moving mechanism pushes out the docking assembly 120 and opens the cover plate 1421 at the window 131 , so that the plug connector 1212 of the power connection terminal 121 moves closer to the bus assembly 110 ;

[0165] The sliding surface 12123 on the plug connector 1212 cooperates with the guide surface 1131 of the guide member 113 to adjust the overall position and orientation of the fixing plate 1121, the positive busbar 111a, and the negative busbar 111b, thereby achieving reliable plugging of the power connection terminal 121 and the busbar assembly 110.

[0166] After the circuits on both sides are ready, the energy storage mechanism can discharge, and the discharged electricity is transmitted to other electrical devices through the power connection terminal 121;

[0167] Other electrical equipment includes but is not limited to mobile energy storage cabinets, backup power supplies, motors, electric vehicles, electric motorcycles, power-assisted bicycles, bicycles, power tools, large household batteries, etc.

[0168] When the power connection terminal 121 needs to be pulled out, the discharge process of the energy storage mechanism is first interrupted, and the power connection terminal 121 is withdrawn from the window 131. The cover 1421 automatically covers the window 131 under the action of the reset member 144. The driving member 141 drives the telescopic rod 1411 to extend, and the quadrilateral movable frame 1432 is deformed, so that the first locking block 1422 and the second locking block 1431 are close to each other, completing the locking.
