Description

Technical Field

[0001] The utility model relates to the technical field of wire harnesses, and in particular to a protective structure of a highly flame-retardant new energy vehicle wire harness. Background Art

[0002] The automotive wiring harness is the network body of the automotive circuit. Without the wiring harness, there would be no automotive circuit. The wiring harness refers to the contact terminal made of copper material, which is crimped with the wires and cables, and then the insulator is plastic-pressed on the outside or a metal shell is added. The wiring harness is used to bundle the components to connect the circuit. Compared with other wiring harnesses, the highly flame-retardant new energy vehicle wiring harness has a flame-retardant effect in addition to its original use, and the protective structure of the automotive wiring harness is a structure for clamping and protecting it.

[0003] After searching, the existing Chinese patent announcement number is: CN219904265U, a car chassis wiring harness protection structure, including a fixed seat, the top two sides of the fixed seat are provided with mounting holes, a wire harness frame is fixed between the mounting holes on both sides, a plurality of partitions are fixed between the two side plates of the wire harness frame, a plurality of groups of buffer grooves are provided on the top of the fixed seat, the inner cavity of the buffer groove is provided with a buffer spring and a lower clamp block, and a plurality of groups of upper movable clamps are provided between the inner cavity partitions of the wire harness frame. The automobile chassis wiring harness protection structure passes the wiring harness through the threading cavity of the adjacent partitions respectively, presses the pressing block together with the upper movable clamp under the movable frame to move downward to press the wiring harness, and adjusts the position of the lower clamp block according to the thickness of the wiring harness by the buffer spring in the buffer groove. When all the wiring harnesses are pressed by the upper movable clamp and the lower clamp block, the rotating limit bolt drives the limit plate to move the movable frame to fix the position, so that the upper movable clamp position can be fixed, so as to achieve the purpose of fixing and protecting the wiring harness. The existing wiring harness protection structure is difficult to quickly fix according to the thickness of the wiring harness.

[0004] In the specific implementation manner of the above patent, when in use, the mounting hole on the top of the fixing seat can be used to fix the automobile chassis wiring harness protection structure at the position on the chassis where the wiring harness protection is required, and then the wiring harnesses to be protected are respectively passed through the partition threading cavity, and then the movable frame in the inner cavity of the fixed frame is pressed by the pressing block to drive the upper movable clamp to move downward to compress the wiring harness, and the buffer spring in the buffer groove adjusts the position of the lower clamp block according to the thickness of the wiring harness. When all the wiring harnesses in the threading cavity between the partitions are compressed by the upper movable clamp and the lower clamp block, the limiting bolt is rotated to drive the limiting plate in the inner cavity of the fixed frame to move inward to fix the position of the movable frame, and the upper movable frame can be fixed. The position of the movable clamp is fixed. This patent achieves the purpose of fixing and protecting the wire harness. The existing wire harness protection structure is difficult to quickly fix according to the thickness of the wire harness. However, in this patent, the limit bolts are used to push the limit plate to squeeze and fix the two sides of the movable frame, thereby ensuring that the upper movable clamp clamps the wire harness. The use of lateral force may not provide sufficient clamping force to ensure that the movable frame is firmly clamped, and it is impossible to cooperate with the movable clamp to tightly clamp the wire harness, and it is impossible to ensure the stability of the wire harness fixation, which makes the wire harness easy to loosen or fall off under vibration or impact. Therefore, a highly flame-retardant new energy vehicle wire harness protection structure is proposed to solve the above problems. Utility Model Content
