[0025] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0026] Reference Figure 1-Figure 5 A wiring harness device for monitoring charging and discharging of lithium batteries includes: a wiring harness box 1, which serves as the outer shell of the entire device and plays a role in protecting and fixing the internal components. It provides a closed space to ensure that components such as cables 4 and wiring reels 3 operate in an orderly environment to prevent external interference or damage; a connecting tube 2 is installed in the wiring harness box 1, and the connecting tube 2 is installed in the wiring harness box 1 as an installation carrier of the wiring reels 3, ensuring the linear arrangement between the wiring reels 3, so that the cables 4 can be neatly wound on the wiring reels 3 for easy management and maintenance; a plurality of wiring reels 3 are installed on the connecting tube 2 and distributed in a linear array. The wiring reels 3 are the main support and guide components of the cables 4. Through the wiring reels 3 distributed in a linear array, the cables 4 can be effectively managed and organized to avoid entanglement and confusion. The design of the wiring reels 3 also facilitates the rapid release and recovery of the cables 4; a plurality of cables 4 are respectively wound on a plurality of wiring reels 3. The cables 4 are used to connect the battery and the monitoring equipment. It is a key component for realizing the charge and discharge monitoring of lithium batteries. Through the cable 4, the monitoring equipment can accurately obtain the charge and discharge status of the battery to ensure the safe and efficient use of the battery; the two ends of the cable 4 respectively pass through the two side walls of the cable box 1 and extend to the outside of the cable box 1. The cable 4 is used to connect the battery and the monitoring equipment; a number of second elastic members 202 are installed on the connecting tube 2, and a number of cable wheels 3 are respectively connected to a number of second elastic members 202. The second elastic member 202 is used to provide the cable wheel 3 with a restoring force to the initial position. The second elastic member 202 provides the cable wheel 3 with a restoring force to the initial position, which means that when the cable 4 is released or recovered, the cable wheel 3 can quickly return to the initial position under the action of the spring, and be ready for the next operation, thereby improving the degree of automation of the device and reducing manual intervention.

[0027] The cable pulley 3 includes: a plurality of limiting grooves 3021, which are opened on the outer ring of the cable pulley 3 and distributed in a circular array. The cable pulley 3 is provided with a limiting rod 101, and the bottom end of the limiting rod 101 is set in the limiting groove 3021. The combination of the limiting groove 3021 and the limiting rod 101 ensures the stability and controllability of the cable pulley 3 during the rotation process.

[0028] The cable harness box 1 includes: a groove, which is opened at the top of the cable harness box 1, and a limiting rod 101 passes through the bottom wall of the groove; a pull ring 102, which is installed at the top of the limiting rod 101; a first elastic member 103, one end of which is installed at the bottom wall of the groove, and the other end is installed at the bottom of the pull ring 102. When the cable 4 is wound up, the pull ring 102 is lifted upward, and the pull ring 102 can drive the limiting rod 101 to actively disengage from the limiting groove 3021, and the restriction of the cable wheel 3 can be cancelled. When the second elastic member 202 is wound up, it will undergo elastic deformation and store elastic potential energy. As the second elastic member 202 relaxes, the stored energy is gradually released and converted into kinetic energy, driving the cable wheel 3 to rotate in the opposite direction to wind up the cable 4. The first elastic member 103 ensures that the pull ring 102 can quickly return to its original position after release, providing convenience for the next operation.

[0029] The bottom end of the limit rod 101 is formed with an inclined surface, and the limit rod 101 is used to limit the rotation direction of the cable pulley 3. The inclined surface design of the limit rod 101 allows the cable pulley 3 to rotate when the cable 4 is pulled. The inner wall of the limiting groove 3021 on the cable pulley 3 squeezes the inclined surface of the limit rod 101, and the limit rod 101 can be squeezed and moved upward. As the cable pulley 3 continues to rotate, the limit rod 101 is inserted into another limiting groove 3021 driven by the first elastic member 103. Even when the cable 4 is released, the cable pulley 3 will not reset and rotate.

[0030] The cable pulley 3 is formed with a depression, and the cable 4 is wound in the depression. The depression design on the cable pulley 3 allows the cable 4 to be wound more tightly on the cable pulley 3, reducing the risk of loosening and slipping of the cable 4. This design improves the stability and durability of the cable 4.

[0031] The cable pulley 3 also includes: a bearing 201, which is installed on the inner ring of the cable pulley 3, and the connecting pipe 2 is installed on the inner ring of the bearing 201. The bearing 201 is installed on the inner ring of the cable pulley 3, which reduces the friction and resistance of the cable pulley 3 during rotation, so that the cable pulley 3 can rotate more smoothly, thereby improving the efficiency and reliability of the entire device.

[0032] The second elastic member 202 includes a spring, one end of which is connected to the connecting tube 2 , and the other end of which is connected to the cable pulley 3 .

[0033] One end of cable 4 passes through connecting tube 2 and exits through the inner wall of one side of cable harness box 1. Cable 4 is connected to a first connector 401. The other end of cable 4 passes through the inner wall of the other side of cable harness box 1 and is connected to a second connector 402. The first connector 401 and the second connector 402 are connected to the two ends of cable 4, respectively. These connectors allow cable 4 to be easily connected to the battery and monitoring equipment. The connector design ensures a stable and reliable connection, providing strong support for lithium battery charge and discharge monitoring.

[0034] When the cable 4 reaches the desired length, the user can directly pull one end of the cable 4. The pulling of the cable 4 drives the cable wheel 3 to rotate, and the other end of the cable 4 passes through the connecting tube 2 from the cable wheel 3 and then passes through the connecting tube 2. The other end of the cable 4 will not be displaced by the rotation of the cable wheel 3. The limit rod 101 is squeezed by the inner wall of the limit groove 3021 during the rotation of the cable wheel 3. Since the bottom end of the limit rod 101 is formed with a slope, the limit rod 101 will be squeezed upward and moved. As the cable wheel 3 continues to rotate, the second elastic member 202 is gradually wound up, storing elastic potential energy. When the cable 4 reaches the required length, the cable 4 is released. Due to the release of the elastic potential energy of the clockwork spring, the cable wheel 3 is driven to rotate in the opposite direction. However, since the limit rod 101 has moved to the new limit groove 3021 position, the cable wheel 3 will not reset and rotate, and will maintain the current state. When the cable 4 needs to be reeled in, the user lifts the pull ring 102 upwards, and the pull ring 102 drives the limit rod 101 to actively disengage from the current limit groove 3021. At this time, the second elastic member 202 releases the stored elastic potential energy, converts it into kinetic energy, drives the cable wheel 3 to rotate in the opposite direction, and starts to reel in the cable 4. As the cable 4 is reeled in, when the cable 4 is completely reeled onto the cable wheel 3, the pull ring 102 is released, and the pull ring 102 returns to its original position under the action of the first elastic member 103, providing convenience for the next operation. The two ends of the cable 4 are respectively connected to the first connector 401 and the second connector 402. These connectors enable the cable 4 to be conveniently connected to the battery and the monitoring device. The user connects the first connector 401 to the battery and the second connector 402 to the monitoring device to realize the charge and discharge monitoring of the lithium battery.

[0035] In summary, compared with the existing technology, it has the following beneficial effects:

[0036] Through the linear array distribution of the cable pulleys 3, different cables 4 can be wound on different cable pulleys 3, which makes the management of the cables 4 clearer. In actual use, users can quickly identify and find the required cables, thereby improving work efficiency.

[0037] The cable pulleys 3 are arranged linearly through the connecting tube 2, so that the cables 4 can be neatly wound on the cable pulley 3. The design of the cable pulley 3 enables the cables 4 to be quickly released and recovered. The depression on the cable pulley 3 enables the cables 4 to be more tightly wound on the cable pulley 3, reducing the risk of the cables 4 loosening and slipping.
