Description

Technical Field

[0001] The utility model relates to the technical field of new energy vehicle parts, in particular to a high-voltage interlock wire harness for a new energy vehicle. Background Technique

[0002] The high-voltage interlock wire harness is a component that plays an important safety guarantee role in the high-voltage electrical system. The main function of the high-voltage interlock wire harness is to monitor the integrity and safety of high-voltage connection components. When the high-voltage components are normally connected, the signal circuit in the wire harness remains unblocked; if there is a connection looseness, disconnection or other abnormal conditions, the signal circuit is interrupted, and the system will immediately take corresponding protection measures, such as cutting off the high-voltage power supply, to prevent potential dangers, such as electric leakage and short circuit. In the power battery system of an electric vehicle, the high-voltage interlock wire harness is used to ensure the reliable connection between the battery pack and other high-voltage components of the vehicle.

[0003] The prior art such as the utility model with the publication number of CN216002481U discloses a high-voltage wire harness assembly for a new energy vehicle that realizes the interlock function. This patent adopts a main wire and branch wires on the main wire, and further includes: multiple rows of upper plates, which are respectively fixedly connected to the lower ends of multiple branch wires. Among them, a row of lower plates are arranged at the lower ends of multiple rows of upper plates, and rotating rods are fixedly connected to both sides of the upper ends of multiple lower plates. Rotating holes matched with the rotating rods are arranged on both sides of multiple upper plates; multiple pairs of fixing plates are respectively fixedly connected to both ends of each row of upper plates. Among them, screw holes are arranged at the upper ends of two fixing plates, and two screw holes and multiple rotating rods are connected through an interlock mechanism; in this utility model, the branch wires of the high-voltage wire harness can be fixed more quickly, and the position of the branch wires can be adjusted again after fixation, which is more convenient to use. It solves the problem that in the prior art, after the high-voltage wire harness is installed, in order to prevent multiple branch wires from winding and interfering with each other, multiple fixing buckles are used to fix them on the vehicle. However, there are generally multiple branch wires in the high-voltage wire harness assembly, so it takes a lot of time for the installer to fix the branch wires through the fixing buckles, seriously affecting the work efficiency of the installer.

[0004] During the installation process of the high-voltage interlock wire harness, there is an existing high-voltage interlock wire harness such as the above-mentioned one, which uses an elastic U-shaped plate as a clamping structure. When clamping the wire harness, due to the relatively weak clamping structure, the clamping effect of the clamping structure on the cable is limited, resulting in poor clamping stability of the structure on the cable. Moreover, the distance between the clamping structures is limited, and it is difficult to adjust the distance between the clamping structures according to actual needs during actual use, resulting in poor applicability of the clamping structure. Summary of the Utility Model

[0005] The purpose of the present utility model is to solve the disadvantages that in the prior art, the spacing of the clamping structure is limited, and during actual use, it is difficult to adjust the spacing between the clamping structures according to actual needs, resulting in poor applicability of the clamping structure, and to propose a high-voltage interlock wire harness for new energy vehicles.

The guiding convex block is slidably connected to the inner wall of the sliding groove.

[0008] The restraint assembly further includes a clamping unit. The clamping unit includes a support frame. The support frame is fixedly connected to the upper surface of the connection block. A connection cavity is formed on the upper surface of the support frame. A fastening bolt is threadedly connected to the inner wall of the support frame at the connection cavity.

The load-bearing plate is in contact with the lower surface of the fastening bolt. A damping block is fixedly connected to the lower surface of the load-bearing plate. The damping block is in contact with the upper surface of the assembly plate.

[0009] Preferably, a guiding rod is fixedly connected to the upper surface of the support frame. A guiding hole is formed on the surface of the clamping frame. The guiding rod is slidably connected to the inner wall of the guiding hole. Through the cooperation of the guiding rod and the guiding hole, the moving direction of the clamping frame can be guided.

[0010] Preferably, the number of the positioning rods is two. The two positioning rods are symmetrically arranged front and back with respect to the assembly plate. The length of the positioning rod is equal to the length of the assembly plate. Through the cooperation of the positioning rod and the connection block, the moving direction of the support frame can be guided.

[0011] Preferably, the connection block is in contact with the side surface of the positioning rod. The number of the connection blocks is two. The two connection blocks are symmetrically arranged front and back with respect to the assembly plate. Through the cooperation of the connection block and the guiding convex block, with the assistance of the sliding groove, the position of the support frame can be restricted above the assembly plate.

[0012] Preferably, the support frame is in contact with the upper surface of the positioning rod. The number of the support frames is multiple, and the multiple support frames are horizontally distributed with respect to the positioning rod. The support frames can cooperate with the clamping frame to clamp the high-voltage cable, so as to ensure that the position of the high-voltage cable can be limited.

[0013] Preferably, the fastening bolt penetrates through the lower surface of the clamping frame, and the damping block is slidably connected to the inner wall of the connecting cavity.

When the fastening bolt is completely tightened, the positions of the clamping frame and the support frame can be limited in cooperation with the load-bearing plate and the damping block, and then the locking operation of the wiring harness is completed. By providing the restraint assembly, the stability of the wiring harness in the working state is improved, and the problem that it is difficult to adjust the distance between the clamping structures, resulting in poor applicability of the clamping structures, is reduced, and the reliability of the wiring harness in the working state is further improved.
