Description

Technical Field

[0001] This invention relates to the field of battery technology, and more specifically, to a battery power connection cable with a protection unit. Background Technology

[0002] Batteries, with their ability to efficiently store and release electrical energy, have extremely wide applications in modern society. For example, they are used to power electric vehicles, provide stable and strong power output to drive motors to propel vehicles, or provide a continuous and reliable power supply to other electrical-consuming components.

[0003] Existing power cords have requirements for moisture protection and heat dissipation. In high-humidity environments, inadequate moisture protection can lead to short circuits, reduced insulation, and other safety hazards. Power cords also generate heat during prolonged operation; poor heat dissipation accelerates cord aging and shortens their lifespan. Furthermore, power cords can be pulled, potentially detaching from the battery terminals and causing equipment shutdown. Different installation environments require different power cord lengths; existing power cords, with their fixed lengths, are unsuitable for varying installation needs. Insufficient length prevents proper connection, while excessively long cords result in a tangled and disorganized appearance. Summary of the Invention

[0004] The present invention aims to overcome the shortcomings of the prior art and provide a battery power connection cable with a protection unit.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a power connection cable, comprising a protection unit, a power cord, and a conductive base. The protection unit includes a first protection box and a second protection box. The first protection box includes a first end box with an open bottom and a first cable box with an open top, and has a first through hole. The conductive base is located inside the first end box. The second protection box includes a second end box with an open bottom and a second cable box with an open bottom, and has a second through hole and a third through hole. The power cord passes through all three through holes. The first cable box has two strip-shaped grooves, and the second cable box has two strip-shaped rails fixed thereon. A first ventilation pipe is fixed at the first end box. A second ventilation pipe is fixed at the second end box, and one end of the second ventilation pipe can be inserted into one end of the first ventilation pipe; the first protective box has a first connecting hole, and the first end box has a first ventilation hole communicating with the first ventilation pipe; the second protective box has a second connecting hole, and the second end box has a second ventilation hole communicating with the second ventilation pipe; the first cable box has a first partition forming a first cable space inside the first cable box, and a first end through hole is formed between the first partition and the end of the first cable box; the second cable box has a second partition forming a second cable space inside the second cable box, and a second end through hole is formed between the second partition and the end of the second cable box; a transition space is formed between the first partition and the second partition; and a cooling fan is installed inside the second end box.

[0006] Furthermore, the conductive base is connected to the power cord; the first cable box is fixedly connected to the first end box; the second cable box is fixedly connected to the second end box; the strip slide rail cooperates with the strip slide groove; the first connecting hole connects the space inside the first end box and the space inside the first cable box; the second connecting hole connects the space inside the second end box and the space inside the second cable box.

[0007] Furthermore, the power cord passes sequentially through the first through hole, the first cable space, the first end through hole, the transition space, the second end through hole, the second cable space, the second through hole, and the third through hole.

[0008] Furthermore, temperature sensors are installed in both the first and second cable boxes; a controller is installed in the second end box.

[0009] In some embodiments, the battery connected to the power connection line of this application can be used to power the controller, temperature sensor and cooling fan.

[0010] In other embodiments, an additional battery may be used to power the controller, temperature sensor, and cooling fan.

[0011] Furthermore, the first cable box has two first side plates, and the first cable box has multiple first sliding grooves. A first slider is installed in the first sliding groove, and a first baffle is fixed to the first slider by a first connecting post. The first slider is connected to a first spring, and the first springs of two adjacent first sliders are connected to different first side plates. The second cable box has two second side plates, and the second cable box has multiple second sliding grooves. A second slider is installed in the second sliding groove, and a second baffle is fixed to the second slider by a second connecting post. The second slider is connected to a second spring, and the second springs of two adjacent second sliders are connected to different second side plates. The power cord abuts against all the first connecting posts and all the second connecting posts.

[0012] Thus, the power cord is distributed in a reciprocating pattern within the first and second cable spaces, allowing for a greater length to be pulled out.

[0013] Furthermore, a first guide rod is fixed at the first protective box, and a first limiting channel that cooperates with the first guide rod is at the second protective box; a second guide rod is fixed at the second protective box, and a second limiting channel that cooperates with the second guide rod is at the first protective box; there are two of each of the first guide rod, the second guide rod, the first limiting channel, and the second limiting channel.

[0015] This allows the transition space to maintain a good seal; a good seal is formed between the first protective box and the second protective box.

[0016] Furthermore, both the first end sealing block and the second end sealing block are strip-shaped and made of rubber material; both the first sealing gasket and the second sealing gasket are made of rubber material; the first wire hole connects the space inside the first end box and the space inside the first cable box; the second wire hole connects the space inside the second end box and the space inside the second cable box, and the third wire hole connects to the space inside the second end box.

[0017] Furthermore, the first threading hole has a first sealing ring, the second threading hole has a second sealing ring, and the third threading hole has a third sealing ring; the end of the second ventilation pipe inserted into the first ventilation pipe has a sealing ring.

[0018] Furthermore, the first ventilation duct includes a first straight pipe and a first connecting bend connecting the first straight pipe and the first end box; the second ventilation duct includes a second straight pipe and a second connecting bend connecting the second straight pipe and the second end box.

[0019] This allows for relative displacement between the first and second ventilation ducts, while ensuring a seal between them.

[0020] Furthermore, there are two of each of the first and second ventilation pipes. The first ventilation pipe has multiple first heat dissipation fins, and a heat-conducting plate is connected between the two first ventilation pipes. The heat-conducting plate has multiple second heat dissipation fins.

[0021] This improves heat dissipation.

[0022] Furthermore, the conductive base is U-shaped and has a first locking bolt that locks the conductive base and the battery electrode post; the second end box has two threaded holes, each threaded hole is fitted with a second locking bolt, and the second end box is fitted with two clamping units and two guiding units. The clamping unit includes an arc-shaped clamping plate and a push rod fixedly connected to the arc-shaped clamping plate.

The end of the second locking bolt can abut against the end of the push rod; the first cable box has multiple third locking bolts that lock the relative positions of the first protective box and the second protective box.

[0045] Working principle: The power connection cable of the battery in this application can be stably connected to the conductive base and the battery terminals, and the two are locked together by a first locking bolt. Furthermore, because the power cable can reciprocate within the first cable space, the transition space, and the second cable space (the power cable in the transition space is not necessarily straight but can be curved, thus allowing for greater elongation space), and the user can pull the end of the power cable connected to the load to extend it to the required length, the power cable has sufficient length within the first cable space, the transition space, and the second cable space for elongation. After being extended to the appropriate length, the arc-shaped clamping plate and the power cable can be secured together using the second locking bolt.

[0046] And the relative positions between the first protective box and the second protective box can be as follows: Figure 1 The shorter overall length shown also allows the first and second protective boxes to be in a state where... Figure 2 The overall length shown is relatively long, thus achieving a longer power cord stretch. Furthermore, due to the presence of the first and second end sealing blocks, even when the first and second protective boxes are in a relatively long state... Figure 2 As shown, the transition space can also remain sealed.

[0047] During installation, sealant can be used to fix the first and second protective boxes to the surface of the battery, thus sealing the bottom openings of the first end box, the second cable box, and the second end box. Based on the temperature sensor's detection signal, the cooling fan can be activated, and the cooling airflow circulates between the second end box space, the second cable space, the transition space, the first cable space, the first end box space, the first ventilation duct, and the second ventilation duct, dissipating heat through the first and second ventilation ducts. Furthermore, the cooling airflow is closed, preventing contact with the outside environment, thus achieving better moisture protection.

[0048] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes and modifications can be made to the present invention without departing from the scope defined by the claims.
