Description

Technical Field

[0001] This utility model relates to the field of electric vehicle battery technology, and in particular to a protective structure for battery connection wires. Background Technology

[0002] Currently, the domestic electric vehicle industry generally uses lead-acid batteries, which are stable in low-temperature discharge and have low cost. Battery connection cables, as the bridge for current transmission, are subject to extremely stringent environmental requirements. During use, battery connection cables often encounter the following problems: ① continuous bumps and vibrations during riding; ② easy corrosion of the cable sheath after battery leakage; ③ temperature differences and rain immersion during outdoor use; ④ different current carrying capacities depending on the battery capacity. Therefore, existing technologies typically incorporate protective structures to protect the battery connection cables, slow down their aging, extend their lifespan, and ensure the connection of the electric vehicle battery pack. However, existing protective structures often consist of a protective sleeve wrapped around the battery connection cables to increase their corrosion resistance. Therefore, the existing protective structure and battery connection cables are mostly integrated. However, when the battery connection cables are damaged and need replacement, it is difficult to separate the battery connection cables and protective structure, leading to the replacement of the protective structure along with the battery connection cables, resulting in waste of the protective structure and affecting its practicality and sustainable use. Utility Model Content

[0003] To address the shortcomings of the existing technology, this utility model proposes a protective structure for battery connection wires.

[0004] The technical solution of this utility model is implemented as follows:

[0005] A protective structure for a battery connection wire includes an upper protective portion and a lower protective portion that are spliced ​​together, wherein:

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figures 1-4 As shown, a protective structure for a battery connection wire includes an upper protective portion 1 and a lower protective portion 2 that are spliced ​​together, wherein:

[0028] The upper protective part 1 includes an upper protective sleeve 11, the bottom of the upper protective sleeve 11 is recessed inward to form a semi-circular first groove, and both ends of the upper protective sleeve 11 are provided with terminal protection covers 12.

[0029] The lower protective part 2 includes a lower protective sleeve 21. The top of the lower protective sleeve 21 is recessed inward to form a semi-circular second wire groove. Both ends of the lower protective sleeve 21 are provided with terminal protection lower covers 22. The second wire groove and the first wire groove can be combined to form a circular placement groove. Both the terminal protection lower cover 22 and the terminal protection upper cover 12 are provided with through holes 13. A connecting component 6 for installing and fixing the upper protective part 1 and the lower protective part 2 is also provided between the terminal protection lower cover 22 and the terminal protection upper cover 12. The upper protective sleeve 11 is fitted over the lower protective sleeve 21. Both the upper protective sleeve 11 and the lower protective sleeve 21 are made of insulating material.

[0030] Specifically, the connecting component 6 includes connecting blocks 61 disposed on both sides of the bottom of the terminal protection upper cover 12, a connecting groove 63 for the connecting blocks 61 to be inserted into the terminal protection lower cover 22, and a pin rod 62 inserted into both sides of the terminal protection lower cover 22. The connecting block 61 is provided with a pin hole for the pin rod 62 to be inserted into, and the pin rod 62 and the pin hole are interference fit.

[0031] When protecting the battery connection cable, first place the battery connection cable in the second groove inside the lower protective sleeve 21, so that the two terminals of the battery connection cable are respectively placed into the through holes 13 on the terminal protection lower cover 22. Then, put the upper protective sleeve 11 on the lower protective sleeve 21. At this time, the upper protective sleeve 11 presses the battery connection cable into the second groove through the first groove. At the same time, the connecting block 61 is inserted into the connecting groove 63 to position the terminal protection upper cover 12 and the terminal protection lower cover 22. Then, insert the pin rod 62 into the corresponding pin hole to connect and limit the terminal protection upper cover 12 and the terminal protection lower cover 22, realizing the installation and fixation between the upper protective sleeve 11 and the lower protective sleeve 21. This completes the assembly of the protection structure and realizes real-time protection of the battery connection cable. Finally, put the terminal protection lower cover 22 on the outside of the battery terminal. Insert a screwdriver into the through hole 13 and tighten the battery connector terminal to complete the battery connection. During use, the terminal protection cover 22 limits the connection between the protective structure and the battery terminal, contributing to a stable connection and increasing stability and reliability. This prevents the battery connector from loosening due to vibration. Furthermore, the protective structure provides real-time protection, preventing corrosion of the wiring harness sheath due to battery leakage or rain immersion, thus extending the battery connector's lifespan, reducing the risk of aging, and facilitating its use. The protective structure is also detachable, allowing for easy removal of the battery connector during replacement, further simplifying its use.

[0032] Meanwhile, in this embodiment, such as Figure 3 and Figure 4 As shown, an upper insulating sleeve 14 is installed on the inner wall of the first wire trough, and a lower insulating sleeve 23 is installed on the inner wall of the second wire trough.

[0033] When protecting the battery connection wire, the upper insulating sleeve 14 and the lower insulating sleeve 23 work together to form an inner insulating layer inside the protective structure, while the upper protective sleeve 11 and the lower protective sleeve 21 form an outer insulating layer, thereby achieving multi-layer insulation. This helps to extend the service life of the battery connection wire, reduce the aging risk of the battery connection wire, and ensure the normal use of the battery connection wire.

[0034] Furthermore, such as Figures 1-4 As shown, each of the two terminal protection covers 12 has a cover plate 3 on one side that can block the through hole 13, and a flexible connecting strip 4 is connected between the cover plate 3 and the terminal protection cover 12. The connecting strip 4 can be a component made of rubber.

[0035] After the battery connection cable is connected to the battery terminal, the cover plate 3 can be pulled. At this time, the cover plate 3 causes the connecting strip 4 to bend (e.g., Figure 1As shown, the cover plate 3 covers the terminal protection cover 12 to seal the through hole 13, thereby preventing battery leakage or rainwater from entering and causing corrosion between the battery connection wire and the battery terminal. This facilitates the subsequent disassembly and assembly of the battery connection wire and makes battery maintenance easier.

[0036] Furthermore, such as Figures 3-6 As shown, positioning strips 24 are provided on both sides of the top of the lower protective sleeve 21, and positioning grooves 16 corresponding to the positioning strips 24 are provided at the bottom of the upper protective sleeve 11.

[0037] When the upper protective cover 11 is fitted over the lower protective cover 21, the positioning strip 24 can be inserted into the positioning groove 16 to quickly position the upper protective cover 11 and the lower protective cover 21, thereby facilitating the rapid installation of the upper protective cover 11 and the lower protective cover 21, which is conducive to the precise assembly of the protective structure and facilitates the effective protection of the battery connection wires.

[0038] Furthermore, such as Figures 3-6 As shown, sealing strips 15 are provided on both sides of the inner wall of the upper protective sleeve 11, and sealing grooves 25 that cooperate with the sealing strips 15 are provided on both sides of the bottom of the lower protective sleeve 21.

[0039] When the upper protective sleeve 11 is fitted over the lower protective sleeve 21, the sealing strip 15 can be inserted into the sealing groove 25 to seal the upper protective sleeve 11 and the lower protective sleeve 21. This ensures the sealing performance of the assembled protective structure, which facilitates effective protection of the battery connection wires and prevents corrosion of the wire harness sheath or immersion in rainwater after battery leakage. This, in turn, helps to extend the service life of the battery connection wires and reduce the risk of aging.

[0040] In another embodiment, such as Figures 1-4 As shown, a cable tie assembly 5 is also provided on one side of the upper protective cover 11, and the cable tie assembly 5 includes a connector 53 provided on the side wall of the upper protective cover 11. A cable tie 51 is connected to one side of the connector 53, and a hook and loop fastener 52 is provided on one side of the cable tie 51, and a hook and loop fastener rough surface 55 that cooperates with the hook and loop fastener 52 is provided on the other side, and the length of the hook and loop fastener rough surface 55 is greater than the length of the hook and loop fastener 52.

[0041] During the protection of battery connection cables, adjacent battery connection cables can be bundled together using cable ties 51, and then secured using the hook and loop sides 52 and 55 of the Velcro. This bundles and secures each battery connection cable, preventing them from becoming tangled and facilitating subsequent battery maintenance. It also prevents the battery connection cables from loosening or even coming undone during continuous bumps and vibrations while riding, ensuring a stable connection.

[0042] Meanwhile, in this embodiment, to facilitate the binding and fixing of each battery connection wire, such as... Figures 1-3 As shown, a slider is also provided on the side of the connector 53 away from the cable tie 51, and a groove 54 for sliding the slider is provided on the side wall of the upper protective sleeve 11.

[0043] When securing the battery connection wires with the cable tie 51, the cable tie 51 can be pulled to move the connector 53. The connector 53 moves along the side wall of the upper protective sleeve 11 with the cooperation of the slider and the groove 54, thereby adjusting the position of the cable tie 51. This makes it easier to secure the battery connection wires at different positions, which in turn helps to secure the battery connection wires.

[0044] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
