It should be noted that, for the convenience of description, only the parts related to the utility model are shown in the drawings. In the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0041] In combination with Figures 1-5The battery pack wiring fool-proof assembly disclosed in the application comprises a mounting plate 100 and a first fool-proof part 200, the mounting plate 100 is provided with a first interface 101 and a second interface 102; the first fool-proof part 200 is movably arranged on the mounting plate 100 and can move between a first position and a second position, when the first fool-proof part 200 is in the first position, the first fool-proof part 200 shields the first interface 101, and the first interface 101 cannot be wired, when the first fool-proof part 200 is in the second position, the first fool-proof part 200 avoids the first interface 101 and exposes the first interface 101, and the first interface 101 can be wired.

[0042] The battery pack wiring fool-proof assembly disclosed in the application can be arranged on the shell of the battery pack, and one of the positive and negative poles of the battery pack is arranged at the position of the first interface 101, and the other is arranged at the position of the second interface 102 for wiring. The following is described by taking the negative pole as an example, and the positive pole is arranged at the first interface 101, and the negative pole is arranged at the second interface 102. The arrangement scheme can be referred to each other, and will not be described in detail.

[0043] When wiring two battery packs, in the initial state, the first fool-proof part 200 is in the first position and shields the first interface 101, thereby hiding the negative pole, at this time, only the positive pole at the second interface 102 is exposed, and the operator can only install the connector of one cable 500 on the positive pole, after connecting the positive pole of the battery pack with the cable 500, the operator can move the first fool-proof part 200 from the first position to the second position to expose the negative pole, at this time, the connector of another cable 500 can be connected to the negative pole of the battery pack, and the wiring of a single battery pack is completed.

[0044] Compared with the prior art, the battery pack wiring fool-proof assembly disclosed in the application can be used for the battery pack with the positive and negative poles arranged on the same side, to realize the normalized management of materials and reduce the management cost; one of the positive and negative poles of the battery pack is shielded by the movement of the first fool-proof part 200, so that only one pole can be wired during the wiring of the battery pack, thereby avoiding the risk of electrical short circuit caused by the short circuit of the positive and negative poles of a single battery pack during wiring, realizing the fool-proof design, and greatly improving the safety of the operator.

[0045] Specifically, the first anti-fumble piece 200 can be a plate structure, a mesh structure, etc., and the shape includes but is not limited to a rectangle, a circle, etc., as long as it can partially or completely cover the first interface 101 to prevent normal wiring at the first interface 101. The movement form of the first anti-fumble piece 200 on the mounting plate 100 includes but is not limited to sliding, rotating, and a combination of the two. For example, the first anti-fumble piece 200 can be hinged on the mounting plate 100 and move between the first position and the second position by flipping or rotating to open and close, thereby covering or exposing the first interface 101.

[0046] In a specific embodiment disclosed in the present application, in combination with Figure 1 and Figure 2 , the battery pack wiring anti-fumble assembly further comprises a rotating handle 400, which is rotatably arranged on the mounting plate 100 and can rotate between a first flip point and a second flip point; when the rotating handle 400 is at the first flip point, the rotating handle 400 avoids the movement track of the first anti-fumble piece 200 between the first position and the second position, and when the rotating handle 400 is at the second flip point, the rotating handle 400 is arranged on the movement track and can limit the first anti-fumble piece 200 at the first position, so that after the worker completes the wiring at the second interface 102, the worker must rotate the rotating handle 400 from the second flip point to the first flip point before moving the first anti-fumble piece 200, otherwise the wiring at the first interface 101 cannot be performed, and the action of the worker operating the rotating handle 400 can prompt the worker, avoiding wiring errors and improving safety.

[0047] Further optimization scheme, the rotating handle 400 is provided with prompt information, when the rotating handle 400 is at the first flip point, the prompt information on the rotating handle 400 is used to prompt the wiring of the first interface 101, when the rotating handle 400 is at the second flip point, the prompt information on the rotating handle 400 is used to prompt the wiring of the second interface 102, thereby further avoiding wiring errors of the worker. Specifically, the rotating handle 400 can be a toggle switch with prompt information, when the worker rotates the rotating handle 400 to different points, the prompt information on the rotating handle 400 can be switched synchronously and the wiring prompt can be performed. For example, when the rotating handle 400 is at the first flip point, the rotating handle 400 prompts the negative pole lug of the first interface 101 through color and / or character symbol prompt information, and when the rotating handle 400 is at the second flip point, the rotating handle 400 prompts the positive pole lug of the second interface 102 through color and / or character symbol prompt information. Wherein, the prompt information can be "+" and "-" symbols corresponding to the positive and negative pole lugs.

[0048] For the convenience of installation of the first foolproof part 200, in some embodiments, in combination with Figure 1 The mounting plate 100 is provided with a sliding rail 104, the sliding rail 104 includes a first sliding rail, both ends of the first sliding rail extend to the first position and the second position respectively, and the first foolproof part 200 is slidably arranged on the first sliding rail. Wherein, the type of the first sliding rail includes but is not limited to sliding guide rail, sliding groove and the like. For example, in combination with Figure 2 and Figure 3 which shows a technical solution that the first sliding rail is a sliding groove, specifically, the mounting plate 100 includes a main plate 110 and a cover plate 120, the main plate 110 and the cover plate 120 are connected, and a sliding groove is formed between the two, the first foolproof part 200 is arranged in the sliding groove and can slide to the first position and the second position along the sliding groove, the structure is simple, the installation is convenient, the main plate 110 and the cover plate 120 can be fixed by bonding or screw connection, the structure is simple and the production is convenient.

[0049] Further optimization scheme, the first foolproof part 200 is arranged on one side of the mounting plate 100, and the first foolproof part 200 is provided with a sliding block 211 on the side facing the mounting plate 100, and the sliding block 211 is in sliding cooperation with the first sliding rail. Specifically, in combination with Figure 4 the cover plate 120 is provided with a sliding groove, the first foolproof part 200 is in sliding cooperation with the sliding groove through the sliding block 211, and this kind of first foolproof part 200 is arranged outside the sliding groove, so that the operator can directly move the position by pulling the first foolproof part 200, and the operation is convenient. In addition, when the rotating handle 400 is at the second flip point, the rotating handle 400 can directly abut against and limit the first foolproof part 200.

[0050] In some embodiments, in combination with Figure 3 the first foolproof part 200 is provided with a sliding protrusion 210, the sliding protrusion 210 is exposed to the first sliding rail through the avoiding groove on the cover plate 120, so as to facilitate the operator to realize the movement of the first foolproof part 200 between the first position and the second position by operating the sliding protrusion 210. When the rotating handle 400 is at the second flip point, the rotating handle 400 abuts against and limits the sliding protrusion 210, so as to limit the first foolproof part 200 at the first position, thereby avoiding the free movement of the first foolproof part 200 between the first position and the second position, and ensuring the realization of the foolproof function of the first foolproof part 200 during wiring.

[0051] In a specific embodiment disclosed in the present application, the battery pack wire foolproof assembly further comprises a second foolproof piece 300, which is movably arranged on the mounting plate 100 and is movable between a second position and a third position; when the first foolproof piece 200 is in the first position, the second foolproof piece 300 is in the second position, and when the first foolproof piece 200 is in the second position, the second foolproof piece 300 is in the third position. The second foolproof piece 300 is arranged to prompt the wiring condition at the second interface 102; when the second foolproof piece 300 is in the second position, it indicates that the first interface 101 is blocked at this time, and the wiring of the second interface 102 can be performed; when the wiring of the first interface 101 is needed, the operator needs to first move the second foolproof piece 300 from the second position to the third position, and then move the first foolproof piece 200 from the first position to the second position to expose the first interface 101. Through the process of moving the second foolproof piece 300, the interface conversion operation of the operator can be further prompted, and the situation that the operator makes wiring errors can be prevented.

[0052] For the battery pack stacked into a battery cluster, the positive and negative tabs of the battery pack are usually arranged on the same side, and accordingly, the mounting plate 100 disclosed in the present application is arranged vertically on the battery pack, and the second position can be arranged below the third position, so that before the first foolproof piece 200 is moved to the second position, the second foolproof piece 300 must be moved from the second position to the third position to overcome the gravity to realize "yielding", and this step must be manually operated by a person to realize, so as to avoid the situation that the rotating handle 400 is located at the first turning point where the first foolproof piece 200 cannot be limited in position during transportation, resulting in that the first foolproof piece 200 is freely movable between the first position and the second position, and thus the foolproof effect of the first foolproof piece 200 during wiring can be prevented from being invalid.

[0053] Among them, the second foolproof piece 300 described above can be a plate structure or a net structure, and the shape includes but is not limited to a rectangle, a circle, etc., and the movement form of the second foolproof piece 300 on the mounting plate 100 includes but is not limited to sliding, rotating, and a combination of the two. In some embodiments, the movement cooperation structure between the second foolproof piece 300 and the mounting plate 100 is the same as the movement cooperation structure between the first foolproof piece 200 and the mounting plate 100.

[0054] In some embodiments, in combination Figure 1The mounting plate 100 is provided with a sliding rail 104, the sliding rail 104 includes a second sliding rail, two ends of the second sliding rail extend to a second position and a third position respectively, and the second foolproof part 300 is slidably arranged on the second sliding rail. Wherein, the types of the second sliding rail include but are not limited to sliding guide rails, sliding grooves and the like, which are simple in structure and convenient for production. The second sliding rail can be communicated with the first sliding rail, so that the first foolproof part 200 and the second foolproof part 300 can be slid to the second position respectively. Wherein, the first sliding rail and the second sliding rail can be arranged perpendicular to each other.

[0055] In combination Figure 1 and Figure 2 , along the extension direction of the second sliding rail, the second position can be arranged corresponding to the position of the first interface 101, and the third position can be arranged corresponding to the position of the second interface 102, so as to further realize the prompting function of the second foolproof part 300 to the wiring of the second interface 102.

[0056] For example, in some embodiments, in combination Figure 1 , the first interface 101 is arranged below the second interface 102, in the natural state, before wiring, the rotating handle 400 is located at the downward second turning point, at this time, the first foolproof part 200 and the second foolproof part 300 are arranged on the two sides of the rotating handle 400 respectively, and the first foolproof part 200 covers and hides the negative ear of the battery pack, at this time, the second foolproof part 300 can be slid upward to the third position shown in the dashed box in Figure 1 ; since only the positive ear at the second interface 102 is exposed at this time, it can be avoided that the same cable 500 is connected to the positive and negative ears of the same battery pack at the same time during wiring; after the wiring of the positive ear of the battery pack is completed, the rotating handle 400 needs to be turned to the upward first turning point, and then the second foolproof part 300 and the first foolproof part 200 are moved to the third position and the second position respectively, so that the first interface 101 is exposed, with the rotation of the rotating handle 400 to the first turning point, the warning board 410 is brought out, and the content of the warning board 410 is “! Prohibit the same cable to be connected” or other prompt information, so as to twice remind the operator to pay attention to the electrical short circuit caused by misoperation.

[0057] During actual wiring operation, the operator can adopt the following two ways to wire, the first way is to wire each battery pack of the battery cluster layer by layer; the second way is to wire the positive ear at the second interface 102 of each battery pack in the battery cluster first, after all the wiring is completed, the first foolproof part 200 is operated to expose the first interface 101 of each battery pack, and then the wiring of the negative ear of each battery pack is performed.

[0058] For the second wiring method, in order to improve the wiring efficiency of the operator, in combination Figure 6The battery pack wiring fool-proof assembly further comprises a first auxiliary tool, and the first auxiliary tool comprises a pull rod 600, and a plurality of pull rings 601 are arranged on the pull rod 600 at intervals. In the wiring process, the sliding protrusions 210 on each battery pack can be embedded in each pull ring 601 one by one, and are pulled by the operating personnel to operate the pull rod 600 to simultaneously move the plurality of first fool-proof pieces 200 from the first position to the second position, thereby improving the position moving efficiency of the first fool-proof piece 200 and further improving the wiring efficiency. Exemplarily, the first auxiliary tool can be prepared by bending a single metal wire.

[0059] Further optimization scheme, in order to facilitate the operating personnel to simultaneously operate the plurality of battery packs on the battery cluster to jointly rotate the rotating handle 400, in combination with Figure 7 The battery pack wiring fool-proof assembly further comprises a second auxiliary tool, and the second auxiliary tool comprises a connecting rod 700 and a plurality of toggle rods 710, the plurality of toggle rods 710 are arranged on the connecting rod 700 at intervals, and the interval between adjacent two toggle rods 710 corresponds to the interval of the rotating handles 400 on adjacent two battery packs on the battery cluster, and the operating personnel can simultaneously toggle the plurality of rotating handles 400 to switch between the first flip point and the second flip point by lifting the connecting rod 700, thereby improving the wiring efficiency.

[0060] The battery pack wiring fool-proof assembly disclosed in the application can be combined with the cable 500 to realize fool-proof design. Specifically, the connectors at both ends of the cable 500 can be designed to be different in color and shape, which facilitates the operating personnel to distinguish and connect with the positive and negative poles of the battery pack, thereby reducing the probability of wiring failure.

[0061] In addition, the communication interface 103 and other structures can also be arranged on the mounting plate 100 according to actual conditions, which will not be described herein.
