[0047] Hereinafter, specific embodiments of the present utility model will be described in more detail with reference to the accompanying drawings. These drawings show representative embodiments of the present utility model and do not limit the present utility model.

[0048] As Figure 1 、 Figure 2 shown. A floating nut assembly 100 provided by the present utility model is used to absorb the assembly error during the connection of a board 150. The floating nut assembly 100 includes:

[0049] A mounting base;

[0050] A plurality of nuts, at least some of the plurality of nuts are adjustably assembled on the mounting base along a predetermined direction; and

[0051] A plurality of bolts, which are used to cooperate with the corresponding nuts to connect the superposed boards.

[0052] The floating nut assembly includes a plurality of nuts and a plurality of bolts. The nuts and bolts cooperate to connect the superposed boards, that is, the floating nut assembly can connect multiple groups of superposed boards. Since it is inevitable that the board 150 has manufacturing errors and assembly tolerances, if the connection assembly cannot absorb the corresponding tolerances, it may cause the nuts 110 and bolts 130 to be difficult to cooperate for stably connecting the board 150. The present utility model is provided with a plurality of nuts 110 that cooperate with the bolts 130 to connect and fix the superposed boards 150. The nuts 110 are adjustably assembled with the mounting base 120, and each nut 110 can be adjusted accordingly to absorb the manufacturing errors and assembly tolerances of the board 150, which helps to improve the assembly accuracy of the floating nut assembly 100 and effectively reduces the risk of loose connection or even inability to assemble caused by tolerances.

[0053] In one embodiment, the mounting base 120 includes a receiving cavity 121 for receiving the nut 110. The height of the receiving cavity 121 in the first direction is greater than the height of the nut 110 in the first direction, such that the nut 110 can move in the first direction within the receiving cavity 121.

[0054] Specifically, the nut 110 as a whole is received in the receiving cavity 121 with a height slightly greater than that of the nut 110 to achieve adjustable movement of the nut 110 in the height direction and absorb the absorption tolerance in the first direction. The first direction is the direction in which the sheets 150 are stacked. It can be understood that there will inevitably be a certain degree of misalignment or uneven stacking surfaces in the stacking direction. At this time, the nut 110 and the mounting base 120 are assembled adjustably in the first direction. When the bolt 130 is connected to the nut 110 to connect the sheets 150, the nut 110 can be adjusted and moved in the first direction on the mounting base 120. That is, without moving the bolt 130, the nut 110 can be adjusted accordingly to fit the sheets 150 and absorb the assembly tolerance between the sheets 150.

[0055] In addition, the nut 110 is provided with a second adjustment portion 113 in the second direction. Correspondingly, the mounting base 120 is provided with a second mating portion 123 to achieve adjustable installation of the nut 110 and the mounting base 120 in the second direction, so as to achieve adjustment in the first direction and the second direction. The second direction is set at a preset angle to the first direction.

[0056] In one embodiment, as Figure 5 shown, the nut 110 includes a nut body 111 and a first adjustment portion 112. The nut body 111 is connected to the first adjustment portion 112. The receiving cavity 121 includes a first mating portion 122 adapted to the first adjustment portion. The height of the first mating portion 122 in the first direction is greater than the height of the first adjustment portion 112 in the first direction, such that the nut 110 can be adjusted in the first direction on the mounting base 120.

[0057] If multiple adjustment portions need to be provided on the nut 110 to achieve multi-dimensional adjustability to absorb tolerances, although tolerances in multiple directions can be absorbed, there will also be a risk of unstable connection, which is not conducive to the stability of assembly. Preferably, the nut 110 is divided into a nut body 111 and a first adjustment portion 112. The first adjustment portion 112 is used to adjust the up and down of the nut 110, that is, the tolerance in the first direction, to achieve the least mutual influence in adjustment to the greatest extent.

[0058] Specifically, the nut body 111 and the first adjusting portion 112 are arranged along the first direction. Further, the nut body 111 can be disposed above the first adjusting portion 112, that is, the nut body 111 is disposed on the side close to the plate 150 to be connected. Optionally, the nut body 111 can also be disposed below the first adjusting portion 112. Optionally, the first adjusting portion 112 can also be disposed in the middle of the nut body 111.

[0059] Optionally, the first adjusting portion 112 can also be disposed on the side of the nut body 111. That is, the nut body 111 is disposed in the middle for connection and fixation with the bolt 130, and the first adjusting portion 112 is disposed on the peripheral side of the nut body 111 for adjusting the up and down movement of the nut 110.

[0060] Optionally, the nut body 111 and the first adjusting portion 112 are arranged along the first direction, and the peripheral side of the nut body 111 protrudes from the first adjusting portion 112, that is, the dimension of the first adjusting portion 112 along the second direction or the third direction is smaller than the dimension of the nut body 111. The second direction is perpendicular to the first direction, and the third direction is perpendicular to the first direction and the second direction respectively. Correspondingly, the first fitting portion 122 protrudes from the side wall of the receiving cavity 121. At this time, the height of the first adjusting portion 112 along the first direction is greater than the height of the first fitting portion 122 along the first direction, so that the nut 110 can be adjusted and moved along the first direction in the receiving cavity 121.

[0061] Preferably, the peripheral side of the first adjusting portion 112 protrudes from the nut body 111. Correspondingly, the first fitting portion 122 forms a groove relative to the side wall of the receiving cavity 121 for receiving the first adjusting portion 112. Further, the height of the first fitting portion 122 along the first direction is greater than the height of the first adjusting portion 112 along the first direction, so that the nut 110 can be adjusted and moved along the first direction in the receiving cavity 121.

[0062] In an embodiment, the nut 110 is provided with a second adjusting portion 113 along the second direction, and the mounting base 120 is provided with a second fitting portion 123 adapted to the second adjusting portion 113. The nut 110 is adjustably assembled on the mounting base 120 in the second direction.

[0063] The second direction is perpendicular to the first direction.

[0064] Specifically, as Figure 3 、 Figure 4As shown, the first direction is the stacking direction of the plate 150, and the second direction is perpendicular to the first direction. That is, on the plane of the plate 150, since through holes for the bolts 130 to pass through are provided on the plate 150, it is inevitable that there are errors in the aperture and shape of the through holes during manufacturing. If there are no adjusting components in the horizontal direction, it may be difficult to install the plate 150 firmly due to the accumulation of manufacturing tolerances during assembly. Therefore, a second adjusting portion 113 needs to be provided on the nut 110, and a second matching portion 123 adapted to the second adjusting portion 113 is provided on the mounting base 120, so as to realize the adjustable installation of the nut 110 on the mounting base 120 in the second direction.

[0065] In one embodiment, the nut 110 includes a nut body 111 and a first adjusting portion 112. The nut body 111 and the first adjusting portion 112 are arranged along the first direction, and the second adjusting portion 113 is provided on the nut body.

[0066] Specifically, the first adjusting portion 112 is used to adjust the movement of the nut 110 along the first direction of the mounting base 120, and the second adjusting portion 113 enables the nut 110 to be adjusted along the second direction of the mounting base 120. By separately setting the adjustments in the first direction and the second direction on the first adjusting portion 112 and the second adjusting portion 113, it can ensure to a certain extent that the nut 110 absorbs the assembly tolerances in a single direction, reduce the mutual influence in all directions, ensure the stability of the connection of the floating nut assembly 100, and improve the overall assembly accuracy of the floating nut assembly 100.

[0067] Optionally, the second adjusting portion 113 is set as a protrusion, and the second matching portion 123 is set as a groove. The groove is configured to be recessed into the side wall of the mounting base 120. The protrusion of the second adjusting portion 113 is arranged in the middle of the groove and is configured to move along the second direction inside the groove. Specifically, the length of the groove along the second direction is slightly larger than the length of the protrusion along the second direction, so that the nut 110 can move along the second direction in the mounting base 120.

[0068] In one embodiment, the second adjusting portion 113 is a groove, the groove is configured to be recessed towards the center of the nut body 111, the second matching portion 123 is a protrusion towards the center of the nut body, and the length of the second matching portion along the second direction is slightly larger than the length of the second adjusting portion along the second direction, so that the protrusion can move along the second direction inside the groove, that is, it can drive the nut 110 to move along the second direction in the mounting base 120, and can absorb the assembly tolerances in the second direction during the assembly process of the plate 150.

[0069] Furthermore, when the first adjustment portion 112 protrudes from the nut body 111, and the second adjustment portion 113 is provided on the nut body 111, when the nut body 111 is positioned above the first adjustment portion 112, the second mating portion 123 protrudes from the first mating portion 122, forming a first recess in the first mating portion 122. The raised first adjustment portion 112 is accommodated in the first recess, allowing the first adjustment portion 112 to move in the first direction. In this case, the second mating portion 123 is a protrusion that corresponds to the upper wall of the first recess, effectively improving space utilization.

[0070] In one embodiment, the mounting base 120 is provided with an escape portion 125 . The escape portion 125 is provided on a side of the nut 110 away from the plate along the first direction, that is, below the nut 110 , for escaping the bolt 130 .

[0071] It is understandable that due to the small size differences between the bolts 130, if different components use different bolts 130, it is easy to cause confusion on the production line. During the battery pack assembly process, in order to reduce the occurrence of misplaced bolts 130, facilitate assembly and subsequent after-sales maintenance, bolts 130 with consistent size and specifications are usually used. To reduce the installation mismatch between the bolts 130 and the mounting base 120, a certain amount of space can be left under the nut 110 to allow for smooth assembly of the longer nut 110, thereby improving the adaptability of the floating nut assembly 100.

[0072] In one embodiment, the mounting base 100 is configured to be connected to the first component 140, and the mounting base 120 and the first component 140 are adjustably connected along a third direction, and the third direction is set at a preset angle with the first direction and the first direction respectively.

[0073] Specifically, floating nut assemblies 100 are typically used to connect and secure the busbars of a battery pack. To ensure the stability of the mounting base 120, the mounting base 120 is assembled within the battery pack. The first component is the internal structure of the battery pack, which can be other structures such as a horizontal beam or longitudinal beam on a tray. The mounting base 120 needs to be connected to the first component 140 of the battery pack. Generally, the position of the busbar is difficult to change, and the busbar aperture and shape may have manufacturing errors. The connection between the mounting base 120 and the first component 140 may also have assembly errors. Therefore, the mounting base 120 and the first component 140 need to be adjustable along a third direction to accommodate manufacturing errors and assembly tolerances.

[0074] In one embodiment, a connecting portion 141 is provided on the first member 140, and a mounting portion 124 adapted to the connecting portion 141 is provided on the mounting base. The mounting portion 124, and / or a third adjusting portion is provided on the connecting portion 141. The third adjusting portion is used to adjustably connect the mounting base 120 and the first member 140 in a third direction.

[0075] Specifically, in order to achieve the adjustable connection between the mounting base 120 and the first member 140 in the third direction, the mounting portion 124 of the mounting base 120 can be set as a slider, and the connecting portion 141 of the first member 140 is set as a slide rail. The slide rail extends along the third direction, and the slider moves along the slide rail in the third direction, which can absorb the mounting tolerance and manufacturing tolerance between the mounting base 120 and the first member 140.

[0076] Optionally, a lead screw is provided on the first member 140 along the third direction. One end of the mounting base 120 is fixedly connected to the lead screw. The lead screw is used to control the movement of the mounting base 120 along the third direction to absorb the manufacturing tolerance and assembly tolerance in the third direction.

[0077] Optionally, a plurality of mounting holes evenly distributed along the third direction are provided on the first member 140, and an assembly hole adapted to the mounting hole is provided on the mounting base 120. The floating nut 110 further includes a fixing member passing through the assembly hole and the mounting hole to connect the first member 140 and the mounting base 120. The mounting base 120 can be mounted in different mounting holes along the third direction to adjust the tolerance in the third direction.

[0078] In one embodiment, a first connection hole is provided in the connecting portion, the mounting portion is a second connection hole, and the floating nut assembly further includes a fastener 142. The fastener is adapted to pass through the first connection hole and the second connection hole to connect the mounting base and the first member 140.

[0079] The aperture of the first connection hole, and / or the second connection hole along the third direction is greater than the length of the fastener along the third direction, enabling the movable assembly of the first member 140 and the mounting base in the third direction.

[0080] Specifically, the aperture of the first connection hole, and / or the second connection hole along the third direction is greater than the length of the fastener 142 along the third direction, enabling the mounting base 120 to move and adjust along the first member 140 in the third direction to absorb the assembly tolerance in the third direction. Compared with the slider, lead screw, and multiple evenly distributed mounting hole methods, this solution requires no other components, has a simple process, and does not occupy extra space.

[0081] In one embodiment, the adjustable range of the first adjusting portion 112, the second adjusting portion 113, and the third adjusting portion is less than 5 mm.

[0082] Specifically, since the floating nut assembly 100 is designed to absorb the assembly tolerance between the nut 110 and the mounting base 120 during the connection of the plate 150, it can be understood that the assembly tolerance is relatively small, that is, the adjustment range is relatively small. If the adjustment range is too large, it may affect the connection stability. Therefore, the preferred adjustable range given in this embodiment is less than 5 mm.

[0083] In addition, the floating nut assembly 100 can achieve adjustment in any one direction of the first direction, the second direction, or the third direction, or can achieve adjustment in any two directions. Preferably, the components of the floating nut 110 cooperate with each other to achieve adjustment in the three directions of up and down, left and right, and front and back.

[0084] In one embodiment, the material of the nut 110 and / or the mounting base 120 is metal or plastic.

[0085] Specifically, under the condition of meeting the connection strength of the floating nut assembly 100, the materials of the nut 110 and the mounting base 120 can be metal or plastic. The material selection can be comprehensively considered according to factors such as insulation performance requirements and structural strength.

[0089] Specifically, the battery cell includes a pole post, and the pole post is used to lead out the power of the battery cell to the external electrical equipment. Optionally, the battery cell includes two pole posts, and the pole posts can be a positive pole post and a negative pole post. Optionally, the two pole posts can both be positive pole posts or both be negative pole posts. The battery assembly also includes multiple busbars, and the busbars are connected to the pole posts or external electrical equipment for current collection and conduction. The floating nut assembly is used to connect and fix the stacked busbars.

[0090] Optionally, the busbar can be used to connect adjacent battery cells, that is, as Figure 1 shown, fixing holes adapted to the floating nut assembly are provided on the busbar, and the connection of multiple fixing holes makes the assembly more stable.
