Description

Technical Field

[0001] This utility model relates to the field of wire harness fixing, and in particular to a wire harness fixing device for temperature acquisition of new energy vehicle batteries. Background Technology

[0002] Wiring harness fixing is widely used in the automotive, aerospace, and electronics industries. It not only needs to ensure stable electrical connections but also effectively prevent wiring from loosening or being damaged due to vibration, temperature differences, or external forces. With the rapid development of new energy vehicles, the high power and high heat characteristics of battery systems place higher demands on wiring harness fixing. New energy vehicle battery temperature acquisition wiring harness fixing devices have emerged to address this need. They not only ensure the stable fixing of temperature sensor wiring harnesses but also effectively prevent damage to the wiring harnesses caused by temperature changes or vibrations, thereby ensuring accurate temperature control and safe operation of the battery management system.

[0003] Traditional battery temperature acquisition harness fixing devices for new energy vehicles generally consist of multiple components, mainly including fixing clamps, support frames, and harness guide rails. The fixing clamps securely fix the temperature acquisition harness to the surface of the battery module or battery pack, ensuring that the harness will not shift or loosen due to vibration or other external forces. The support frame typically supports and fixes the overall structure of the sensor and harness, preventing high temperatures or vibrations from affecting sensor performance. The harness guide rails help arrange the harness along a specific path, avoiding interference with other parts of the battery module, while also ensuring the harness's heat dissipation and stability.

[0004] Traditional battery temperature acquisition harness mounting devices for new energy vehicles are typically non-removable. This means that when sensors need to be replaced, maintained, or inspected, the entire mounting device must be disassembled or damaged. This not only increases the complexity of maintenance but also damages the mounting device and wiring harness, affecting the long-term stability of the system. Furthermore, when the battery system malfunctions or requires upgrades, the inability to quickly disassemble and replace the mounting device significantly prolongs maintenance time, increases costs, and impacts the overall vehicle's operational efficiency. In addition, the inability to flexibly change wiring or sensor positions according to actual needs results in poor flexibility and affects the adaptability of the equipment. Utility Model Content

Furthermore, it enhances the reliability and accuracy of the battery temperature acquisition system during long-term operation. Attached Figure Description

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.

[0033] Reference Figures 1-3 This utility model provides an embodiment of a new energy vehicle battery temperature acquisition harness fixing device, including a fixing component 2. A connecting shaft 4 is rotatably connected inside the fixing component 2. The connecting shaft 4 can drive a retaining pin 5 to rotate, allowing the retaining pin 5 to smoothly engage in the retaining groove of a fixing component 3, thus initially connecting the fixing component 2 and the fixing component 3 together. The retaining pin 5 is fixedly connected to the side wall of the connecting shaft 4. A disassembly assembly is provided on the upper surface of the fixing component 2, including a fixing component 3. The fixing component 3 is located at the bottom of the fixing component 2 and supports the fixing assembly, forming the entire fixing device. The upper structure of the fixture provides the installation base. The retaining shaft 5 is slidably connected inside the second fixing part 3. The outer wall of the retaining shaft 5 is threaded with a rotating cap 6. The rotating cap 6 is made of plastic and has a certain degree of toughness and wear resistance. It can be used to tighten the second fixing part 3 through thread engagement, which is common knowledge and will not be elaborated on here. The rotating cap 6 is slidably connected inside the second fixing part 3. When the rotating cap 6 is tightened on the retaining shaft 5, it will be locked into the internal groove of the second fixing part 3, so as to achieve the effect of firmly fixing the first fixing part 2 and the second fixing part 3. The top of the second fixing part 3 is provided with a cable 1 and a fixing component.

[0034] Reference Figure 4 and Figure 5The fixing component includes a fixing block 7, the lower surface of which is fixedly connected to the top of the fixing part 2 3. The fixing block 7 can connect the fixing part 2 3 and the connector 1 8, providing a stable mounting carrier for the upper connection structure and ensuring the overall structural stability of the fixing component. The upper surface of the fixing block 7 is fixedly connected to the connector 1 8, which is made of metal and has high strength and wear resistance. It can provide a fulcrum for rotation, which is common knowledge and will not be elaborated further here. The side wall of the connector 1 8 is rotatably connected to the connecting plate 1 14, and the side wall of the connector 1 8 is rotatably connected to the connecting plate 2 17. The connecting plate 2 17 and the connecting plate 1 14 extend from both sides of the connector 1 8 respectively, forming a symmetrical support structure, providing a balanced force base for the wire harness fixing operation, and can stably support the connector 2 9 and the connector 3 10. The side wall of the connecting plate 1 14 is fixedly connected to the connector 3. 10. Connector 2 9 is fixedly connected to the side wall of connecting plate 2 17. Connector 2 9 is rotatably connected to the side wall of connecting arm 11. The rotatable connection between connecting arm 11 and rotating plate 13 ensures the synchronization of their movement, so that the power of rotating plate 13 can be transmitted to connecting arm 11, avoiding jamming or disengagement during movement. Fixing member 3 15 is fixedly connected to the side wall of connecting member 3 10. Rotating plate 13 is rotatably connected to the side wall of fixing member 3 15. Connector 11 is rotatably connected inside rotating plate 13. Locking plate 16 is fixedly connected to the side wall of fixing member 3 15. Locking plate 16 is fixedly connected to the side wall of rotating plate 13. Locking plate 12 is fixedly connected to the side wall of rotating plate 13. When external force is applied by the operator, locking plate 12 drives rotating plate 13 to rotate, thereby realizing the opening and closing operation of the entire fixed assembly and improving the convenience of operation.

[0035] Working principle: First, the temperature acquisition harness to be fixed is passed between connector 2 (9) and connector 3 (10). Then, the slot of fixing part 2 (3) is aligned with the locking shaft 5, and fixing part 1 (2) is fixed to the new energy vehicle battery. Rotating the connecting shaft 4 causes the locking shaft 5 to rotate, so that the locking shaft 5 is engaged in the slot of fixing part 2 (3). Rotating the rotating cap 6 until the rotating cap 6 is engaged in the slot of fixing part 2 (3) fixes fixing part 2 (3). Then, rotating the locking plate 12 causes the rotating plate 1 to rotate. 3 and connecting arm 11 rotate, rotating plate 13 is connected in fixing part three 15, connecting arm 11 drives connecting part two 9 to retract inward with connecting plate two 17 as the axis until the temperature acquisition wire harness can be fastened. When disassembly is required, rotate locking plate 12 in the opposite direction. Locking plate 12 drives connecting arm 11 to rotate. Connecting arm 11 drives connecting part two 9 to rotate outward, which can loosen the temperature acquisition wire harness. Rotate rotating cap 6 in the opposite direction until the retaining shaft 5 can disengage from the retaining part two 3, and then retaining part two 3 can be removed.
