Detailed Implementation

[0035] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0036] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0037] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0038] In the description of this application, it should be noted that if terms such as "upper," "lower," "inner," or "outer" are used to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship that the utility model product is usually placed in during use, they are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0039] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0040] It should be noted that, where there is no conflict, the features in the embodiments of this application can be combined with each other.

[0041] In related technologies, the positive and negative output terminals of the energy storage battery pack are fixedly connected to a connector, forming one positive and one negative terminal. Therefore, only two external wires can be connected: one fixed to the connector and electrically connected to the positive output terminal, and the other fixed to the connector and electrically connected to the negative output terminal. Because these energy storage batteries only have two terminals, they cannot meet the demand for connecting more external wires. Changing the connector would require redeveloping the connector and the front panel for supporting and fixing it, resulting in high costs and long development cycles due to new mold creation. Therefore, current energy storage batteries struggle to balance cost and the need for more external wires.

[0042] Therefore, this application provides a wiring device with a positive conductive element and a negative conductive element, each forming at least two wiring structures to meet the need for connecting more external wires. Furthermore, it eliminates the need to modify battery pack-related structures (such as connectors and front panels), saving development costs.

[0043] Figure 1 This is a partial schematic diagram of an energy storage battery in one embodiment of this application. Figure 1 As shown in the figure, the energy storage battery provided in this embodiment includes a battery pack and a wiring device 100 disposed in the battery pack. The battery pack includes a battery box and battery modules (not shown in the figure) disposed in the battery box. The battery modules have a positive output terminal and a negative output terminal, which are electrically connected to the wiring device 100. The wiring device 100 forms at least four wiring structures, each of which can be used to connect an external wire.

[0044] Optionally, the battery box includes a front panel 10, on which a connector 20 is provided. The positive and negative output terminals are fixed to a connector and connected to a wiring device 100 via the connector 20. In one specific embodiment, the positive and negative output terminals and the wiring device 100 can be fixed to the connector 20 with bolts, and an electrical connection is formed between the positive and negative output terminals and the wiring device 100. The positive output terminal and the wiring device 100 can be directly connected or indirectly connected through a conductive structure; similarly, the negative output terminal and the wiring device 100 can be directly connected or indirectly connected through a conductive structure. In the prior art, external wires are directly fixed to the connector 20 and electrically connected to either the positive or negative output terminal. Since the connector 20 only provides two connection points, only two wires can be connected. This embodiment of the application provides a wiring device 100, which expands to at least four wiring structures, thus allowing at least four wires to be connected, meeting the need for more external wires.

[0045] Figure 2 This is a first schematic diagram of the wiring device 100 in one embodiment of this application; Figure 3 This is a second schematic diagram of the wiring device 100 in one embodiment of this application. For example... Figure 2 and Figure 3 As shown, the wiring device 100 provided in this embodiment includes a support base 110, a positive conductive element 130, a negative conductive element 140, and a protective cover 120. The positive conductive element 130 and the negative conductive element 140 are disposed on the support base 110, and the protective cover 120 is movably disposed on the support base 110. The positive conductive element 130 is provided with one positive connection structure 131 and at least two positive wiring structures 132, and the negative conductive element 140 is provided with one negative connection structure 141 and at least two negative wiring structures 142. The protective cover 120 is used to cover or expose the positive wiring structure 132 and the negative wiring structure 142. Specifically, in this embodiment, the protective cover 120 has a first position and a second position relative to the support base 110. When the protective cover 120 is in the first position, it covers the positive wiring structure 132 and the negative wiring structure 142; when it is in the second position, the positive wiring structure 132 and the negative wiring structure 142 are exposed. Figure 2 In the middle, the protective cover 120 is in the first position; in Figure 3In this embodiment, the protective cover 120 is in the second position. The positive conductive element 130 is electrically connected to the positive output electrode via the positive connection structure 131, and the negative conductive element 140 is electrically connected to the negative output electrode via the negative connection structure 141. The positive conductive element 130 can be electrically connected to at least two external wires via at least two positive wiring structures 132, and the negative conductive element 140 can be electrically connected to at least two external wires via at least two negative wiring structures 142. The aforementioned external wires can be wires connecting to a motor or other electrical equipment. Specifically, in this embodiment, the positive conductive element 130 has two positive wiring structures 132, and the negative conductive element 140 has two negative wiring structures 142. In other embodiments, the number of positive wiring structures 132 and negative wiring structures 142 can be increased according to the required number of external wires.

[0046] In this embodiment, the support base 110 is made of insulating material, serving to support and fix the positive conductive component 130 and the negative conductive component 140, and to maintain electrical isolation between the positive conductive component 130 and the negative conductive component 140. Optionally, the material of the support base 110 includes aliphatic polyamide engineering plastics, such as a mixture of polyamide 66 (or nylon-66, PA66) and glass fiber, with the glass fiber having a specific gravity of 30%. The combination of polyamide 66 and glass fiber has better insulation and flame retardant effects, thereby effectively preventing short circuits between the positive conductive component 130 and the negative conductive component 140 and improving safety.

[0047] Optionally, the support base 110 may be partially wrapped with plastic coating to cover the positive conductive component 130 and a portion of the negative conductive component 140, exposing the positive wiring structure 132, the positive connection structure 131, the negative wiring structure 142, and the negative connection structure 141. Using plastic coating ensures the bonding strength between the support base 110 and the positive and negative conductive components 130 and 140, thereby guaranteeing the stability of the positive and negative conductive components 130 and reducing the use of fasteners.

[0048] Figure 4 This is a cross-sectional view of a wiring device 100 in one embodiment of this application. Figure 4 As shown, in this embodiment, the support base 110 forms a first wiring groove 114 and a second wiring groove 115; the positive terminal wiring structure 132 is located at the bottom of the first wiring groove 114, and the negative terminal wiring structure 142 is located at the bottom of the second wiring groove 115. By providing the first wiring groove 114 and the second wiring groove 115, a space can be provided for the end of the external wire, and the wire connected to the positive terminal wiring structure 132 and the wire connected to the negative terminal wiring structure 142 can be effectively separated, reducing the risk of short circuit between the two.

[0049] Specifically, the support base 110 includes a first blocking portion 111, a separating portion 113, and a second blocking portion 112 arranged sequentially at intervals in the first direction X. A first wiring groove 114 is formed between the first blocking portion 111 and the separating portion 113, and a second wiring groove 115 is formed between the second blocking portion 112 and the separating portion 113. The first wiring groove 114 and the second wiring groove 115 are arranged at intervals in the first direction X.

[0050] In this embodiment, the first wiring groove 114 and the second wiring groove 115 are disposed on the same side of the support base 110, and the first wiring groove 114 and the second wiring groove 115 have top openings facing the same direction; wherein, the top opening of the first wiring groove 114 and the bottom of the first wiring groove 114 are spaced apart in the depth direction of the first wiring groove 114, and the top opening of the second wiring groove 115 and the bottom of the second wiring groove 115 are spaced apart in the depth direction of the second wiring groove 115. For ease of description, the bottom of the first wiring groove 114 is defined as the first bottom 114a, and the top opening of the first wiring groove 114 is defined as the first top opening 114b; the bottom of the second wiring groove 115 is defined as the second bottom 115a, and the top opening of the second wiring groove 115 is defined as the second top opening 115b. In this embodiment, the depth directions of the first wiring groove 114 and the second wiring groove 115 are consistent and parallel to the second direction Y, and the second direction Y is perpendicular to the first direction X.

[0051] In this embodiment, at least one end of the first wiring slot 114 and the second wiring slot 115 is open in the third direction Z, so that the wires connected to the positive terminal wiring structure 132 and the negative terminal wiring structure 142 can pass through; wherein, the third direction Z is perpendicular to the first direction X and the second direction Y.

[0052] In this embodiment, when the protective cover 120 is in the first position, it covers the first top opening 114b of the first wiring groove 114 and the second top opening 115b of the second wiring groove 115. This prevents hands or other external objects from approaching and contacting the positive conductive element 130, the negative conductive element 140, or the wires along the depth direction of the first wiring groove 114 and the second wiring groove 115, thereby reducing the risk of electric shock and improving safety. When the protective cover 120 is in the second position, it opens the first top opening 114b of the first wiring groove 114 and the second top opening 115b of the second wiring groove 115. Optionally, the protective cover 120 can be made of the same material as the support base 110, such as a mixture of polyamide and glass fiber, thus possessing high insulation and flame-retardant properties.

[0053] In this embodiment, the protective cover 120 is rotatably connected to the support base 110, and the protective cover 120 switches between a first position and a second position by flipping. Figure 5This is an exploded view of the wiring device 100 in one embodiment of this application. Figure 5 As shown, one of the support base 110 and the protective cover 120 may be provided with a shaft hole 121, and the other may be provided with a rotating shaft 116 that mates with the shaft hole 121, thereby realizing a rotatable connection between the support base 110 and the protective cover 120. In this embodiment, the rotating shaft 116 is provided in the first blocking part 111 and the second blocking part 112, and the shaft hole 121 is provided in the protective cover 120.

[0054] Furthermore, one of the protective cover 120 and the support base 110 is provided with a locking protrusion 122, and the other of the protective cover 120 and the support base 110 is provided with a locking groove 117. When the protective cover 120 is in the first position, the locking protrusion 122 is engaged with the locking groove 117. By providing the locking groove 117 and the locking protrusion 122, when the protective cover 120 is in the first position, more external force is required to disengage the locking groove 117 and the locking protrusion 122, thereby flipping the protective cover 120. This improves the reliability of the protective cover 120 in the first position, thereby improving the protective performance of the protective cover 120. In this embodiment, the locking protrusion 122 is provided on the protective cover 120, and the locking groove 117 is provided on the support base 110; specifically, the first blocking part 111 on the side opposite to the first wiring groove 114 and the second blocking part 112 on the side opposite to the second wiring groove 115 are both provided with locking grooves 117. Optionally, the locking groove 117 can be a through hole structure or a groove structure.

[0055] In alternative embodiments, the protective cover 120 may also slide with the support base 110 to switch between a first position and a second position.

Figure 6 As shown, the positive electrode conductive component 130 includes a positive electrode connecting portion 133, a positive electrode transition portion 134, and a positive electrode wiring portion 135 connected in sequence.

Further, the positive electrode conductive component 130 is a bent copper busbar, specifically made of T2 copper. The junction between the positive electrode connecting portion 133, the positive electrode transition portion 134, and the positive electrode wiring portion 135 is a bent portion. In this embodiment, the thickness direction of the positive electrode connecting portion 133 and the positive electrode wiring portion 135 is the second direction Y, and the thickness direction of the positive electrode transition portion 134 is the third direction Z. The positive electrode connecting portion 133 and the positive electrode wiring portion 135 are respectively connected to the two ends of the positive electrode transition portion 134 in the second direction Y.

[0057] Figure 7This is a schematic diagram of the negative electrode conductive element 140 in one embodiment of this application. Figure 7 As shown, the negative electrode conductive component 140 includes a negative electrode connecting portion 143, a negative electrode transition portion 144, and a negative electrode wiring portion 145 connected in sequence. A negative electrode connecting structure 141 is disposed on the negative electrode connecting portion 143, and negative electrode wiring structures 142 are all disposed on the negative electrode wiring portion 145. A support base 110 encloses at least a portion of the negative electrode transition portion 144. Further, the negative electrode conductive component 140 is a bent copper busbar, specifically made of T2 copper. The junction between the negative electrode connecting portion 143, the negative electrode transition portion 144, and the negative electrode wiring portion 145 is a bent portion. In this embodiment, the thickness direction of the negative electrode connecting portion 143 and the negative electrode wiring portion 145 is the second direction Y, and the thickness direction of the negative electrode transition portion 144 is the third direction Z. The negative electrode connecting portion 143 and the negative electrode wiring portion 145 are respectively connected to the two ends of the negative electrode transition portion 144 in the second direction Y.

[0058] In this embodiment, the positive electrode connection structure 131 is a through hole formed in the positive electrode conductive element 130 (specifically, the positive electrode connection portion 133), and the negative electrode connection structure 141 is a through hole formed in the negative electrode conductive element 140 (specifically, the negative electrode connection portion 143). Through the through holes and the use of bolts, the positive electrode conductive element 130 and the negative electrode conductive element 140 can be tightly connected to the connector 20, achieving connection with the positive and negative output terminals. In other embodiments, the positive electrode connection structure 131 and the negative electrode connection structure 141 can also be in other forms, such as notches.

[0059] In this embodiment, the positive terminal connection structure 132 includes a press-fit nut connected to the positive conductive component 130. Specifically, the positive terminal portion 135 of the positive conductive component 130 is provided with a mounting hole, and the press-fit nut is interference-fitted with the mounting hole, so that the end face of the press-fit nut is flush with the surface of the positive terminal portion 135. The press-fit nut has an internal thread, which can be screwed onto the press-fit nut with a bolt, thereby pressing the wire against the positive terminal portion 135 to achieve good electrical contact. The press-fit nut is connected to the positive conductive component 130 through an interference fit, and has good torsional strength. Similar to the positive terminal connection structure 132, the negative terminal connection structure 142 in this embodiment also includes a press-fit nut connected to the negative conductive component 140. The negative terminal portion 145 of the negative conductive component 140 is provided with a mounting hole, and the press-fit nut is interference-fitted with the mounting hole, so that the end face of the press-fit nut is flush with the surface of the negative terminal portion 145. In other optional embodiments, the positive terminal wiring structure 132 and the negative terminal wiring structure 142 can also be other structures, such as through holes, screw holes, notches, etc., provided on the positive terminal wiring structure 132 / negative terminal wiring structure 142.
