[0033] Combination Figure 2 and Figure 3 According to an embodiment of the present invention, a battery module conversion and capacity testing mechanical unit 100 is provided for easy battery module replacement, including a frame 101, a base plate 102 and a battery testing assembly.
[0034] The battery testing assembly includes multiple power modules D, and multiple sets of needle bed assemblies 104 corresponding one-to-one with the multiple power modules D.
[0035] Specifically, the frame 101 encloses a power module area to accommodate power modules D, and multiple power modules D are installed within this area. A bed of needles assembly 104 is installed below the base plate 102. (As shown...) Figure 3 As shown, a set of needle bed assemblies 104 includes a positive probe module 104a and a negative probe module 104b.
[0036] To make this utility model clearer, the orientation of the battery module replacement and capacity-forming mechanical unit 100 provided by this utility model is marked as: front end, rear end, left side, and right side, as follows. Figure 2 As shown.
[0037] like Figure 2 As shown, multiple power modules D are arranged in multiple columns from left to right, and multiple sets of needle bed assemblies 104 are arranged in multiple columns from left to right, with one power module D corresponding to one set of needle bed assemblies 104.
[0038] The formation and capacity-enhancing mechanical unit 100 also includes a changing mechanism 108, which is installed at the front and rear ends of the unit. The changing mechanism 108 is detachably connected to the needle bed assembly 104 and the power module D. The changing mechanism 108 drives a set of needle bed assemblies 104 and a power module D to move synchronously along the left and right sides, adjusting the spacing between multiple sets of needle bed assemblies 104. For example, a set of needle bed assemblies 104 and a power module D can be connected by a connector to achieve synchronous movement.
[0039] Combination Figure 2 and Figure 3 At the rear end of the forming and composting mechanical unit 100, a first rod 103 extending in the left and right directions is fixed, and a second rod 106 extending in the left and right directions is fixed.
[0040] Specifically, the two ends of the first rod 103 are fixed to the left and right sides of the frame 101; the two ends of the second rod 106 are fixed to the bottom of the base plate 102.
[0041] like Figure 3As shown, a set of needle bed assemblies 104 and a power module D are taken as an example, the needle bed assemblies 104 and the power module D are connected through a wire L1. The needle bed assemblies 104 and the power module D are connected through a wire L2.
[0042] Corresponding to a set of needle bed assemblies 104 and a power module D, a first cable tie ring 105 is sleeved on the first rod 103, and the first cable tie ring 105 is freely slidable on the first rod 103.
[0043] Corresponding to a set of needle bed assemblies 104 and a power module D, a second cable tie ring 107 is sleeved on the second rod 106, and the second cable tie ring 107 is freely slidable on the second rod 106.
[0044] The first cable tie ring 105 and the second cable tie ring 107 are tied with a set of wire L2 of the needle bed assemblies 104 and a power module D.
[0045] In this embodiment, corresponding to a set of needle bed assemblies 104 and a power module D, two first cable tie rings 105 are sleeved on the first rod 103. The wire L2 is tied with the two first cable tie rings 105, and the wire L2 connected to the power module D forms a first wire excess L21, and the wire L2 between the two first cable tie rings 105 forms a third wire excess S1.
[0046] In this embodiment, corresponding to a set of needle bed assemblies 104 and a power module D, two second cable tie rings 107 are sleeved on the second rod 106. The wire L2 is tied with the two second cable tie rings 107, and the wire L2 connected to the needle bed assemblies 104 forms a second wire excess L22, and the wire L2 between the two second cable tie rings 107 forms a fourth wire excess S2.
[0047] When the battery module is changed (the battery module model is replaced, the battery module column number is changed), a set of needle bed assemblies 104 and a power module D are driven by the changing mechanism 108 to move synchronously along the left and right sides, and the distance between the needle bed assemblies 104 is adjusted accordingly, so that the battery module is changed.
[0048] The working process of the battery module changing forming and dispensing mechanical unit 100 will be described below.
[0049] When the battery module needs to be changed (the battery module model is replaced, the battery module column number is changed), the changing mechanism 108 moves between the left and right sides of the battery module changing forming and dispensing mechanical unit 100 to adjust the distance between the needle bed assemblies 104.
[0050] Specifically, as Figure 3As shown, take a group of needle bed assembly 104 and a power module D as an example. When the needle bed assembly 104 and the power module D are moved from the left side to the right side of the formation and distribution mechanical unit 100 by the type changing mechanism 108, the first wire slack L21 of one end of the wire L2 connected to the power module D, and the second wire slack L22 of one end of the wire L2 connected to the needle bed assembly 104 are moved with the needle bed assembly 104 and the power module D from the left side to the right side of the formation and distribution mechanical unit 100.
[0051] The first wire slack L21 drags a first cable ring 105 to slide on the first rod 103, and when the distance between the two first cable rings 105 reaches the length of the third wire slack S1, another first cable ring 105 follows the third wire slack S1 to slide on the first rod 103.
[0052] Similarly, the second wire slack L22 drags a second cable ring 107 to slide on the second rod 106, and when the distance between the two second cable rings 107 reaches the length of the fourth wire slack S2, another second cable ring 107 follows the fourth wire slack S2 to slide on the second rod 106.
[0053] When the battery module is changed, the first cable ring 105 and the second cable ring 107 drive the wire L2 of the needle bed assembly 104 and the power module D to move synchronously, so that the wire L2 smoothly follows the needle bed assembly 104 and the power module D to move, without the need to unbind the wire L2, realizing mechanical type changing operation.
[0054] When the battery module is changed, the wire L2 of each group of needle bed assembly 104 and each power module D moves with the corresponding needle bed assembly 104 and power module D, and the wire L2 of the multiple groups of needle bed assembly 104 and the multiple power modules D is more regular, avoiding the disorder and accumulation of the wire L2 of the multiple groups of needle bed assembly 104 and the multiple power modules D.
[0055] Although the embodiments of the utility model have been shown and described above, it can be understood that the above-mentioned embodiments are exemplary and cannot be understood as limiting the utility model, and those skilled in the art can change, modify, replace and modify the above-mentioned embodiments within the scope of the utility model.
