Description

Technical Field

[0001] This utility model belongs to the technical field of new energy battery module parts, specifically relating to a protective cover with a waterproof structure at the docking end. Background Technology

[0002] The wiring harness and new energy battery module docking protection cover is an important component used in new energy vehicle battery systems to protect the electrical connection parts of the battery module. The main function of the protection cover is to cover and protect the electrical connection points between the battery module and the wiring harness to prevent short circuits or poor contact. It is usually made of high-strength, weather-resistant plastics (such as polypropylene PP, polycarbonate PC) or metal materials.

[0003] Wiring harness and new energy battery module docking protective covers are indispensable components in battery systems. Through their unique design and function, they ensure the safety, reliability, and durability of electrical connections. In the development of new energy vehicles and energy storage systems, the role of these protective covers will become increasingly important.

[0004] While the protective cover design for the connection between the wiring harness and the battery module provides some protection in existing new energy vehicle and energy storage system applications, significant shortcomings remain in practical use. Due to the gaps between the wiring harness and the protective cover, moisture can easily penetrate into the battery module's connection points in humid environments or when exposed to rain, leading to a series of problems. Prolonged moisture erosion can cause rust on the metal components at the connection points, affecting not only the stability of the electrical connection but also potentially causing poor contact due to rust buildup. More seriously, if the rust continues to worsen or an electrical fault occurs, it could potentially trigger a short circuit, posing a serious threat to the safety of the battery system and even the entire vehicle. Utility Model Content

[0005] The purpose of this utility model is to provide a protective cover with a waterproof structure at the docking end, which aims to solve the problem of gaps between the wire harness and the protective cover when using existing wire harness and new energy battery module docking protective covers. In humid environments or when exposed to rain, moisture can easily penetrate into the connection of the battery module through these gaps. Long-term moisture erosion will cause rust on the metal parts at the connection, which not only affects the stability of the electrical connection, but may also cause poor contact due to the accumulation of rust. If the rust continues to deteriorate or an electrical fault occurs, it is very likely to cause a short circuit, which poses a serious threat to the safety of the battery system and even the entire vehicle.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a protective cover with a waterproof structure at the docking end, comprising a first half-shell, a second half-shell, and a wire channel. The wire channel is connected through the surface of the first half-shell. A slot is provided on the side surface of the first half-shell. A sealing ring is provided on the inner wall of the wire channel. A locking block is connected to the side surface of the sealing ring. A fixing ear is connected to the side surface of the sealing ring. A fixing hole is opened on the surface of the fixing ear. A fixing bolt passes through the inside of the fixing hole. An internally threaded tube is connected through the side surface of the first half-shell near the fixing bolt.

[0007] As a preferred embodiment of the present invention, the protective cover with a waterproof structure at the docking end has four sets of slots and blocks arranged in a ring array on the surface of the sealing ring, and the blocks and slots form an engaging structure.

[0008] As a preferred embodiment of the present invention, the protective cover with a waterproof structure at the docking end is provided in which the fixing lug, fixing hole, fixing bolt and internal threaded tube are symmetrically arranged on both sides of the sealing ring, and the fixing bolt and the internal threaded tube are connected by threads.

[0009] As a preferred embodiment of the present invention, a protective cover with a waterproof structure at the docking end is provided, wherein a guide groove is provided on the surface of the second half shell, an extension plate is connected to the inner wall of the first half shell, a guide block is connected to the side surface of the extension plate, a threaded hole is provided on the surface of the guide block, a fastening bolt is inserted into the threaded hole, and a pressure plate is sleeved on the surface of the fastening bolt.

[0010] As a preferred embodiment of the present invention, a protective cover with a waterproof structure at the docking end is provided in two sets of guide grooves and guide blocks, wherein the guide block is slidably connected to the second half-shell through the guide groove.

[0011] As a preferred embodiment of the present invention, a protective cover with a waterproof structure at the docking end is provided with two sets of fastening bolts and pressure plates, and the fastening bolts and threaded holes are connected by threads.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This utility model utilizes a combination of a locking block, a locking groove, a fixing ear, a fixing hole, a fixing bolt, and an internally threaded tube to install a sealing ring inside the wire channel. This allows the sealing ring to seal the wire harness as it passes through the wire channel, preventing rainwater from seeping in through the gaps between the wire harness and the wire channel. This prevents rainwater from entering and causing corrosion at the connection points, thus reducing the lifespan of the new energy battery or even posing a danger.

[0014] In this invention, the second half-shell drives the guide groove to slide on the surface of the guide block and then rotates the fastening bolt in the opposite direction. When the fastening bolt rotates in the reverse direction inside the threaded hole, it can rotate towards the guide block. When the fastening bolt moves laterally, it squeezes the second half-shell through the pressure plate to fix the position of the second half-shell. In this way, the length of the protective shell can be adjusted by adjusting the distance between the first half-shell and the second half-shell, thereby improving the practicality and applicability of the protective shell.

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.

[0023] Please see Figures 1-5The present invention provides the following technical solution: a protective cover with a waterproof structure at the docking end, comprising a first half shell 1, a second half shell 2 and a wire channel 3, wherein the wire channel 3 is connected through the surface of the first half shell 1, a slot 4 is provided on the side surface of the first half shell 1, a sealing ring 5 is provided on the inner wall of the wire channel 3, a locking block 6 is connected to the side surface of the sealing ring 5, a fixing ear 7 is connected to the side surface of the sealing ring 5, a fixing hole 8 is provided on the surface of the fixing ear 7, a fixing bolt 9 is passed through the inside of the fixing hole 8, and an internally threaded tube 10 is connected through the side surface of the first half shell 1 near the fixing bolt 9.

[0024] When using this protective cover, first pass the automotive wiring harness connected inside the new energy battery module through the wire channel 3 inside the first half-shell 1, and then install the protective cover on the surface of the new energy battery module. This can protect the connection between the wiring harness and the new energy battery module.

[0025] Preferably, four sets of slots 4 and blocks 6 are arranged in a ring array on the surface of the sealing ring 5, and the blocks 6 and slots 4 form an engaging structure.

[0026] In practical use, the sealing ring 5 is installed by the locking block 6 and locked inside the slot 4. This restricts the position of the sealing ring 5 and prevents it from shifting during use.

[0027] Preferably, the fixing lug 7, fixing hole 8, fixing bolt 9 and internal threaded tube 10 are symmetrically arranged on both sides of the sealing ring 5, and the fixing bolt 9 and internal threaded tube 10 are threadedly connected.

[0028] In practical use, when the fixing bolt 9 passes through the fixing hole 8 and is threaded to the internal threaded tube 10, the position of the fixing ear 7 can be fixed by the fixing bolt 9, thereby fixing the position of the sealing ring 5.

[0029] Preferably, the surface of the second half shell 2 is provided with a guide groove 11, the inner wall of the first half shell 1 is connected with an extension plate 12, the side surface of the extension plate 12 is connected with a guide block 13, the surface of the guide block 13 is provided with a threaded hole 14, a fastening bolt 15 is inserted into the threaded hole 14, and a pressure plate 16 is sleeved on the surface of the fastening bolt 15.

[0030] Preferably, there are two sets of guide grooves 11 and guide blocks 13, and the guide blocks 13 are slidably connected to the second half shell 2 through the guide grooves 11.

[0031] In practical use, when the second half-shell 2 is subjected to force, it can drive the guide groove 11 to slide on the surface of the guide block 13, so that the distance between the second half-shell 2 and the first half-shell 1 can be adjusted, thereby making it convenient to adjust the length of the protective cover.

[0032] Preferably, there are two sets of fastening bolts 15 and pressure plates 16, and the fastening bolts 15 and threaded holes 14 are connected by threads.

[0033] In practical use, when the fastening bolt 15 rotates inside the threaded hole 14, it can move laterally. When the fastening bolt 15 moves laterally, it can squeeze the side surface of the second half shell 2 through the pressure plate 16. In this way, the position of the second half shell 2 can be fixed by squeezing the second half shell 2 through the pressure plate 16.

[0034] Working principle: When using this protective shell, firstly, the sealing ring 5 drives the locking block 6 to be inserted into the slot 4, and the sealing ring 5 drives the fixing hole 8 to move to the side of the internal thread tube 10 through the fixing ear 7. At this time, the fixing bolt 9 passes through the fixing hole 8 and moves to the opening of the internal thread tube 10 and rotates. When the fixing bolt 9 rotates, it can move laterally into the internal thread tube 10. In this way, the fixing ear 7 can be fixed by the fixing bolt 9, thereby fixing the position of the sealing ring 5. When the wire harness passes through the wire channel 3, it can be sealed by the sealing ring 5, thereby preventing rainwater from seeping in from the gap between the wire harness and the wire channel 3.

[0035] When the length of the protective shell is not suitable for use, the fastening bolt 15 can be rotated first. When the fastening bolt 15 rotates inside the threaded hole 14, it can rotate away from the guide block 13. At this time, the second half shell 2 can be pulled. When the second half shell 2 is under tension, it can drive the guide groove 11 to slide on the surface of the guide block 13. When the second half shell 2 moves to the appropriate position, the fastening bolt 15 can be rotated in the opposite direction. When the fastening bolt 15 rotates in the opposite direction inside the threaded hole 14, it can rotate closer to the guide block 13. The lateral movement of the fastening bolt 15 can squeeze the second half shell 2 through the pressure plate 16. In this way, the position of the second half shell 2 can be fixed on the surface of the extension plate 12. This allows the distance between the first half shell 1 and the second half shell 2 to be adjusted, thereby adjusting the length of the protective shell.

[0036] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
