In addition, in the description of the present invention, "a plurality" means two or more unless specifically limited otherwise.

Referring to fig. 1 to 6, a copper bar fixing structure 10 and a battery pack using the copper bar fixing structure 10 provided by the present application will now be described.

The copper bar fixing structure 10 comprises a base 11, a top cover 12, a limiting group 13 and a partition plate 14.

The base 11 is used for connecting a base. The base 11 may be connected to the base by a conventional snap-fit structure, or may be connected to the base by other means. Preferably, the lower surface of the base 11 is provided with a back adhesive, and the back adhesive is adhered to the base. The adhesive tape is adopted, so that the base does not need to be provided with holes or other matched designs, and the structural integrity is kept. Meanwhile, the connection position of the copper bar fixing structure 10 and the base can be selected more freely. In addition, the base may be a battery module 30 by means of adhesive. In other words, the base 11 is directly attached to the battery module 30 without an additional structure as a base to be connected to the base 11, thereby facilitating simplification of the structure.

The top cover 12 is detachably connected with the base 11 and encloses to form a containing cavity which is through from front to back. The top cover 12 and the base 11 are arranged up and down, and the top cover 12 is opened to enable the copper bar 20 to be placed into the accommodating cavity from the upper part; the top cover 12 is closed to enclose the copper bar 20 therein.

The limiting groups 13 are provided in plurality and spaced from top to bottom, and each limiting group 13 includes a left limiting block 131 disposed on the left cavity wall of the accommodating cavity and a right limiting block 132 disposed on the right cavity wall of the accommodating cavity.

At least one partition 14 is detachably connected with the base 11 and is positioned between two adjacent limiting groups 13.

Wherein, the lowest limiting group 13 and the cavity bottom of the accommodating cavity form an assembly layer for fixing a copper bar 20, and the limiting group 13 and the partition plate 14 above the partition plate 14 form an assembly layer for fixing a copper bar 20. The left limiting block 131 and/or the right limiting block 132 can be elastically deformed to avoid the movement of the copper bar 20 downwards placed into the assembly layer and reset when the copper bar 20 is located in the assembly layer so as to limit the copper bar 20 to leave the assembly layer.

In this embodiment, left stopper 131 and right stopper 132 are elastic buckle, and left stopper 131 and right stopper 132 homoenergetic enough take place elastic deformation in order to dodge the removal that copper bar 20 set into the assembly layer downwards. In other embodiments, the left limiting block 131 is an elastic buckle and the right limiting block 132 is a rigid member, and in the process of placing the copper bar 20 into the assembly layer, the copper bar 20 needs to be inclined first, so that the right side of the copper bar is inserted into the assembly layer first and then the left side of the copper bar is pressed into the assembly layer. Similarly, the left stopper 131 is a rigid member and the right stopper 132 is an elastic buckle, so that the assembling operation between the copper bar 20 and the assembling layer can be realized by the way of obliquely placing the copper bar 20. In comparison, the left limiting block 131 and the right limiting block 132 are both elastic buckles, so that the copper bar 20 can be placed into the assembly layer downwards in a horizontal state on the plate surface, and the convenience of operation is improved.

Referring to fig. 3 and 6, the left stopper 131 and the right stopper 132 are both elastic buckles and have protruding blocks protruding toward the accommodating cavities, upper surfaces of the protruding blocks are inclined downward to form guide surfaces for guiding the copper bar 20 to move downward, and lower surfaces of the protruding blocks are pressing surfaces for limiting the copper bar 20 to move upward.

The copper bar fixing structure 10 provided by the embodiment can fix one or more copper bars 20 with different heights at the same time. One mounting layer is used to fix one copper bar 20. The number of the copper bars 20 that can be fixed by the copper bar fixing structure 10 is determined by the assembling layer. The assembling layers are arranged up and down, and for the fixation of the copper bar 20 with a specific height, the corresponding assembling layer can be selected according to the height of the copper bar 20 for fixation. In other words, each assembly layer is independently arranged, each assembly layer has two assembly states of fixing the copper bar 20 and leaving the copper bar, and whether any assembly layer is fixed with the copper bar 20 does not influence the assembly states of other assembly layers above or below the copper bar 20 and the copper bar 20.

Taking two assembly layers as an example, referring to fig. 3 to 6, two limiting groups 13 are arranged above and below each other, and one partition 14 is arranged between the two limiting groups 13. For convenience of description, the upper and lower buildup layers are respectively named an upper buildup layer and a lower buildup layer, and the two limit groups 13 are respectively named an upper limit group and a lower limit group.

When two copper bars 20 are to be assembled on the copper bar fixing structure 10, the top cover 12 is opened, and the first copper bar 20 is placed into the cavity bottom of the accommodating cavity from the upper side and placed in the lower assembly layer. In the insertion process, the first copper bar 20 passes through the upper limit bit group, the upper assembly layer and the lower limit bit group in sequence. When the first copper bar 20 passes through the upper limit bit group and the lower limit bit group, the guide surfaces of the corresponding left limiting block 131 and the right limiting block 132 are abutted against the first copper bar 20, the left limiting block 131 and the right limiting block 132 are elastically deformed under the abutting against of the first copper bar 20, the first copper bar 20 continues to move downwards under the guide of the guide surfaces, when the first copper bar 20 departs from the guide surface of the upper limit bit group and reaches the upper assembly layer, the left limiting block 131 and the right limiting block 132 of the upper limit bit group reset, and when the first copper bar 20 departs from the guide surface of the lower limit bit group and reaches the lower assembly layer, the left limiting block 131 and the right limiting block 132 of the lower limit bit group reset. The pressing surface of the lower limit group and the cavity bottom of the containing cavity clamp the first copper bar 20 together to fix the first copper bar 20. Then, the partition 14 is connected to the base 11. The space enclosed by the partition 14 and the upper limit position is the upper assembling layer. The second copper bar 20 is placed into the receiving cavity from above and placed on the partition 14. During the embedding process, the second copper bar 20 needs to pass through the upper limit bit group. When the second copper bar 20 passes through the upper limit bit group, the guide surface of the upper limit bit group presses against the second copper bar 20, the left limit block 131 and the right limit block 132 elastically deform under the pressing of the second copper bar 20, the second copper bar 20 continues to move downwards under the guide of the guide surface, when the second copper bar 20 leaves the guide surface of the upper limit bit group and reaches the upper assembly layer, the left limit block 131 and the right limit block 132 of the upper limit bit group reset, and the pressing surface of the upper limit bit group and the upper surface of the partition plate 14 clamp the second copper bar 20 together to fix the second copper bar 20. And finally, covering the top cover 12 to finish assembly.

In the case where the copper bar fixing structure 10 is to be assembled with one copper bar 20, the copper bar 20 may be fixed to the upper assembling layer or the lower assembling layer. When the copper bar 20 is to be fixed on the lower assembly layer, the top cover 12 is opened, the copper bar 20 is placed into the cavity bottom of the accommodating cavity from the upper side and placed in the lower assembly layer, and the top cover 12 is closed to complete assembly. When the copper bar 20 is to be fixed on the upper assembly layer, the top cover 12 is opened, the partition plate 14 is connected with the base 11, then the copper bar 20 is placed into the cavity bottom of the accommodating cavity from the upper side and placed on the partition plate 14, and finally the top cover 12 is closed, so that the assembly is completed.

In the structure shown in fig. 2, two copper bars 20 are arranged in a vertically staggered manner, and in this case, the copper bars 20 below are assembled on the lower assembly layer when the copper bar fixing structure 10 is adopted for fixing. And to the copper bar 20 of top, when adopting this scheme copper bar fixed knot structure 10 to fix, assemble it in last assembly layer, can satisfy the fixed requirement of these two copper bars 20.

It can be understood that the more the number of the assembling layers of the copper bar fixing structure 10 is, the more the copper bars 20 can be fixed at the same time, and the more the fixing height can be selected. The number of assembly layers is set by a person skilled in the art according to actual needs and is not limited herein.

It can be understood that the upper and lower dimensions of the assembling layer are matched with the thickness of the copper bar 20 to realize the relative fixation between the copper bar 20 and the copper bar fixing structure 10. The size of the assembly layer is set by those skilled in the art according to actual needs, and is not limited herein.

It will be appreciated that the spacing between the assembled layers is determined by the position of each spacing group 13 and the spacer 14. The position of each limiting group 13 and the partition 14 can be adjusted by those skilled in the art according to actual needs to adjust the distance between the assembly layers.

By the above analysis, the copper bar fixing structure 10 and the battery pack using the copper bar fixing structure 10 provided by the embodiment are designed by matching the limiting group 13 and the partition plate 14, so that the copper bar fixing structure 10 has a plurality of independent assembling layers and can fix one or more copper bars 20 with different heights.

It should be noted that, in the copper bar fixing structure 10 provided in this embodiment, the design that the top cover 12 and the base 11 are detachably connected, the design that the left limiting block 131 and/or the right limiting block 132 are elastic buckles, and the design that the partition board 14 and the base 11 are detachably connected provide possibility and convenience for fixing the plurality of copper bars 20. Specifically, copper bar 20 is long and thin strip, and under the general condition, the both ends of copper bar 20 are connected the back earlier with the target structure and then according to the condition of arranging the middle part region of copper bar 20 with establish copper bar fixed knot structure 10 and fix, consequently, during the assembly, copper bar 20 is fixed motionless, buckles into copper bar fixed knot structure 10 rather than inserting copper bar 20 along the axial holding chamber of copper bar fixed knot structure 10 from radial one side of copper bar 20. And with copper bar fixed knot structure 10 along copper bar 20's radial lock-in copper bar 20, the holding chamber needs radial opening to supply copper bar 20 to put into, and each buildup layer also needs to dodge copper bar 20 from radial putting into. The top cover 12 and the base 11 are detachably connected, and the top cover 12 is opened to enable the copper bars 20 to be placed into the accommodating cavity from the radial direction. Because the left limiting block 131 and/or the right limiting block 132 are/is elastic buckles, the copper bar 20 can be elastically deformed to avoid passing through. Because the partition plate 14 is detachably connected with the base 11, when the copper bar 20 needs to be arranged on the assembly layer below the partition plate 14, the partition plate 14 can be separated from the base 11 to avoid the assembly obstruction of the copper bar 20, and then the partition plate 14 is assembled as required. In addition, the partition plate 14 separates the upper and lower two assembly layers, so that the two copper bars 20 adjacent to each other up and down do not interfere with each other and provide rigid support for the copper bars 20 thereon. It is needless to say that the partition 14, the base 11 and the top cover 12 are made of insulating materials to ensure insulation between the two copper bars 20.

In another embodiment of the present application, referring to fig. 6, the base 11 includes a bottom plate 111, and a left supporting plate 112 and a right supporting plate 113 connected to the left and right sides of the bottom plate 111, wherein one side of the top cover 12 is rotatably connected to the left supporting plate 112, and the other side thereof is fastened to the right supporting plate 113.

It is understood that the right surface of the left support plate 112 is the left chamber wall of the accommodating chamber, and the left surface of the right support plate 113 is the right chamber wall of the accommodating chamber. The lower surface of the top cover 12 is an upper cavity wall of the accommodating cavity, and the upper surface of the bottom plate 111 is a lower cavity wall of the accommodating cavity.

The top cover 12 and the base 11 are fastened by one side being switched, so that the top cover 12 and the base 11 are in a connected state and are not easy to lose while the assembly is facilitated.

In another embodiment of the present application, referring to fig. 4 and fig. 6, the base 11 is provided with left and right through insertion holes 101 on both the left chamber wall and the right chamber wall of the accommodating chamber, and two end portions of the partition 14 are respectively inserted into the two insertion holes 101. The partition 14 is connected to the base 11 by means of a plug-in connection, which facilitates the operation.

In other embodiments, the insertion holes are formed in both the partition 14 and the base 11, the partition 14 is inserted into the accommodating cavity and then connected with the base 11 by the bolts (the two ends of the bolts are respectively inserted into the insertion holes of the partition 14 and the base 11), and the partition 14 and the base 11 can be also detachably connected.

In another embodiment of the present application, referring to fig. 4 and 5, the partition 14 includes a plate main body 141, a fastening block 412 at one end of the plate main body 141, and an elastic fastening member 143 at the other end of the plate main body 141, wherein the elastic fastening member 143 can elastically deform to pass through the insertion hole 101 under an external force. When the partition 14 is inserted into the base 11, the latch 142 and the elastic fastener 143 abut against the periphery of the insertion hole 101 to limit the left and right movement of the limiting plate main body 141.

The latch 412 and the elastic fastener 143 may be disposed left and right, or may be disposed right and left. For example, the fixture block 412 and the elastic fastener 143 are arranged left and right, and when the assembly is performed, the partition 14 is aligned with the left insertion hole 101 from the left side of the base 11 and sequentially passes through the two insertion holes 101. When the elastic buckling piece 143 passes through the inserting hole 101, the elastic buckling piece is elastically deformed under the interference of the hole wall of the inserting hole 101 and elastically resets after leaving the inserting hole 101. When the elastic fastener 143 leaves the right insertion hole 101 and is located on the right side of the base 11, the elastic fastener 143 resets to restrict the plate body 141 from moving leftward, and the latch 142 is located on the left side of the base 11 to restrict the plate body 141 from moving rightward. The fixed connection between the partition 14 and the base 11 is realized.

It can be understood that the size of the latch 142 is larger than that of the left insertion hole 101 and the size of the elastic fastener 143 is larger than that of the right insertion hole 101, so that the left and right movement of the board main body 141 can be limited when the latch and the elastic fastener 143 are located at both sides of the base 11.

Preferably, the two insertion holes 101 are arranged in bilateral symmetry. The two insertion holes 101 have the same size, so that the insertion and fixation effect of the partition 14 and the base 11 can be realized no matter the partition 14 is inserted from the left insertion hole 101 or the right insertion hole 101, and the operation is facilitated.

It is understood that the latch 142 may be disposed on the right side of the plate body 141 and the elastic fastener 143 may be disposed on the left side of the plate body 141. The change of the structure position does not influence the assembly effect.

In another embodiment of the present application, referring to fig. 6, in any limiting group 13, there are two left limiting blocks 131 and two right limiting blocks 132. It can be understood that the two left stoppers 131 and the two right stoppers 132 are located at the same horizontal position. One copper bar 20 is pressed against the bottom of the partition board 14 or the accommodating cavity by the two left limiting blocks 131 and the two right limiting blocks 132. This setting can improve the steadiness of copper bar 20. Those skilled in the art can adjust the number of the left stopper 131 and the right stopper 132 according to actual needs, and the number is not limited herein.

In one embodiment, the left stopper 131 and the right stopper 132 in any stopper group 13 are arranged in bilateral symmetry. In this embodiment, the left stopper 131 and the right stopper 132 are integrally disposed with the base 11. This arrangement can simplify the structure. In the structure shown in fig. 6, the left supporting plate 112 is provided with a U-shaped cut-off groove 102 at the left stopper 131, and the upper end of the left stopper 131 is connected to the base 11 at the U-shaped opening of the cut-off groove 102, specifically, connected to the plate body of the left supporting plate 112. With this arrangement, the projection at the lower end of the left stopper 131 can move left and right relative to the cut-off groove 102 under the action of an external force (the left stopper 131 elastically deforms). Correspondingly, the right supporting plate 113 is provided with a U-shaped cut-off groove 102 at the right limiting block 132, and the upper end of the right limiting block 132 is connected with the base 11 at the U-shaped opening of the cut-off groove 102, specifically, connected with the plate body of the right supporting plate 113.

In another embodiment of the present application, referring to fig. 6, on the left supporting plate 112, the left limiting blocks 131 of the vertically adjacent limiting groups 13 are arranged in a staggered manner in the front-rear direction. On the right stay plate 113, the right stoppers 132 of the vertically adjacent stopper groups 13 are disposed in a staggered manner in the front-rear direction. In combination with the above, the left support plate 112 and the right support plate 113 are respectively provided with the cut-off groove 102 at the left limiting block 131 and the right limiting block 132, and the cut-off groove 102 will reduce the structural strength of the left support plate 112 and the right support plate 113. The left limiting block 131 and the right limiting block 132 are arranged in a staggered manner, so that the distance between the cutting grooves 102 is reduced, and the structural strength of the left supporting plate 112 and the structural strength of the right supporting plate 113 are guaranteed.

Further, when each limit group 13 includes two left limit blocks 131 and two right limit blocks 132, the distance between the two left limit blocks 131 of the lower limit group is greater than the distance between the two left limit blocks 131 of the upper limit group, and the distance between the two right limit blocks 132 of the lower limit group is greater than the distance between the two right limit blocks 132 of the upper limit group, so that the inserting hole 101 can be opened between the two lower limit blocks, which is beneficial to improving the space utilization rate in the height direction.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modification, equivalent replacement or improvement made within the spirit and principle of the present invention should be included in the present invention.
