Figure 1 , Figure 2 , Figure 3 and Figure 4 , comprising an external component 100 and an internal component 200.
[0028] The external component 100 includes an external protective layer 110. In order to improve the overall strength of the wiring harness, the circumferential inner wall of the external protective layer 110 is connected to the frame layer 120 by gluing. In order to make the frame layer 120 have a better impact resistance and not affect the bending of the wiring harness, specifically, the circumferential outer wall of the frame layer 120 is provided with a square groove 170 by integral molding, and the side wall of the square groove 170 is connected to a buffer block 150 by embedding. The side wall of the frame layer 120 is connected to a connecting sleeve 160 by gluing. In order to prevent liquid from penetrating into the interior of the wiring harness, the circumferential inner wall of the frame layer 120 is connected to a waterproof layer 130 by gluing. In order to further protect the inner wall of the wiring harness and prevent corrosion, the circumferential inner wall of the waterproof layer 130 is connected to an internal protective layer 140 by gluing, and the internal protective layer 140 is made of fluoroprene rubber.
[0029] The internal component 200 includes a battery cell 210 connected to the circumferential inner wall of the internal protective layer 140 by embedding. In order to prevent the battery cells from sticking to each other, the circumferential outer wall of the battery cell 210 is embedded with a wire frame 220, and the circumferential outer wall of the wire frame 220 is embedded with a filling layer 230.
[0030] Working principle: When the device is in use, the external protective layer 110 is made of corrosion-resistant material to provide external corrosion-resistant protection for the wiring harness, and the waterproof layer 130 uses waterproof material to provide waterproof protection for the wiring harness to prevent liquid from flowing into the interior of the wiring harness and causing corrosion to the battery cell 210. The internal protective layer 140 uses corrosion-resistant material to provide further corrosion-resistant protection for the wiring harness. When the wiring harness is subjected to external impact, the frame of the frame layer 120 will support the wiring harness to resist the impact, and partially absorb the impact through the buffer block 150, while absorbing the force of deformation of the frame layer 120 caused by excessive impact to avoid breakage of the wiring harness.
[0031] Furthermore, in order to make the external protective layer 110 have good corrosion resistance, specifically, the material of the external protective layer 110 is EPDM rubber material, and the thickness of the external protective layer 110 is 2.5 mm.
[0032] Next, in order to make the frame layer 120 strong and corrosion-resistant, specifically, the frame layer 120 is made of aluminum alloy, and the buffer block 150 and the connecting sleeve 160 are made of styrene-butadiene rubber.
[0033] It is worth noting that in order to make the waterproof layer 130 have good waterproof properties, specifically, the material of the waterproof layer 130 is polyvinyl fluoride, and the thickness of the waterproof layer 130 is 1.5 mm.
[0034] In addition, in order to ensure that the wire frame 220 does not affect the bending of the wire harness and has a good fixing effect on the battery cell 210, specifically, the wire frame 220 is made of thermoplastic polyurethane, and the circumferential outer wall of the wire frame 220 is integrally formed with a wire frame for fixing the battery cell 210.
[0035] Finally, in order to prevent the battery cells 210 from being adhered to each other and to have a certain heat dissipation and pressure resistance effect, specifically, the filling layer 230 is made of glass fiber, and the filling layer 230 completely wraps the battery cells 210 and the wire frame 220 .
