[0002] The automotive wire harness is the network main body of the automotive circuit, connecting the electrical and electronic components of the vehicle and enabling them to function. Without the wire harness, there would be no automotive circuit. After the contact terminals made of copper are punched and crimped with the wire and cable, an insulator is molded outside or a metal shell is added, etc., and the wire harness is bundled to form a component for connecting the circuit.

[0003] The existing automotive wire harness fixing structure lacks effective shock absorption measures during use, which makes it extremely easy for the high-frequency or low-frequency vibrations generated by the outside or the vehicle to cause the wire harness fixing structure fixed on the vehicle body to fall off the vehicle body. The loose wire harness drags the connection joint, resulting in poor contact and affecting the normal use of the vehicle. Summary of the Invention

Detailed implementation manners

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0023] A fixing structure for an automotive wiring harness with shock-absorbing function disclosed by the present invention is mainly applied to scenarios where the shock-absorbing effect of the existing fixing structure for an automotive wiring harness is poor.

[0024] Referring to Figures 1 - 7 , a fixing structure for an automotive wire harness with shock absorption function, comprising a vehicle body 1. An accommodation frame 2 is arranged on the upper side of the vehicle body 1. An isolation cover 3 is arranged on the upper side of the accommodation frame 2. A cutting groove is formed on the upper side of the accommodation frame 2. A movable plate 5 is slidably connected in the cutting groove. An energy absorption and shock absorption module 8 is arranged in the accommodation frame 2.

[0027] Specifically, after sorting the automotive wire harness and placing it in the intervals formed by the partition plates 12 on the movable plate 5, the isolation cover 3 is fixed on the accommodation frame 2 by using the rapid disassembly and assembly module 9, so that the lower fixing buckles 6 and the upper fixing buckle 7 can clamp the wire harness on the accommodation frame 2. The accommodation frame 2 is fixed on the vehicle body 1 by using the energy absorption and shock absorption module 8.

[0028] Referring to Figure 3 , Figure 4 , Figure 5 and Figure 6, in a preferred embodiment, one end of each of the two mounting seats 901 and the bottom of the movable plate 5 are rotatably connected through bearings, and the other end is rotatably connected to the same movable block 805 through a bearing. One end of each of the two second rods 802 is bolted to the inner bottom wall of the receiving frame 2, and the other end is rotatably connected to a slider 803 through a bearing. Moreover, two symmetrical chutes 804 are formed in the bottom of the movable plate 5, and the inner walls of the chutes 804 are slidably connected to the outer sides of the sliders 803 on the same side. A cut groove 806 is formed in the inner bottom wall of the receiving frame 2, and the inner wall of the cut groove 806 is slidably connected to the outer side of the movable block 805; round holes are formed in both the first rod 801 and the second rod 802, and the same round rod is rotatably connected in the round holes through bearings. The first rod 801 and the second rod 802 are cross-distributed, and a notch is formed in the movable block 805. A cylinder 807 is slidably connected in the notch. One side of the cylinder 807 away from the movable block 805 is bolted to the inner wall of the cut groove 806. Two symmetrical narrow grooves are formed in the cylinder 807, and the same transmission piece 809 is slidably connected in the narrow grooves; the side of the transmission piece 809 opposite to the movable block 805 is in contact, and one side of the transmission piece 809 away from the movable block 805 is bolted to an airbag one 808. The airbag one 808 is located inside the cylinder 807. A fine hole is formed in the side of the cylinder 807 away from the movable block 805, and an air duct 813 is arranged in the fine hole. One end of the air duct 813 is bolted to the outside of the airbag one 808, and the other end is bolted to an airbag two 815. Moreover, the air duct 813 is communicated with both the airbag one 808 and the airbag two 815; an installation plate 810 is arranged on the outside of the cylinder 807, and one side of the installation plate 810 opposite to the inner wall of the cut groove 806 is bolted. Two symmetrical magnetic pieces 811 are bolted to the sides of the movable block 805 and the installation plate 810 opposite to each other. The magnetic poles of the two magnetic pieces 811 on the same side are the same. Moreover, a rectangular groove 812 is formed in the inner bottom wall of the receiving frame 2, and a movable seat 818 is slidably connected in the rectangular groove 812. One side of the airbag two 815 away from the air duct 813 is bolted to the outside of the movable seat 818. A fixing seat one 814 is bolted to the outside of the air duct 813. One side of the fixing seat one 814 close to the airbag two 815 is bolted to a throat constriction 816. The throat constriction 816 is located outside the air duct 813, and a knob 817 is arranged on the outside of the throat constriction 816; a fixing seat two 820 is bolted to the inner bottom wall of the receiving frame 2. One side of the fixing seat two 820 close to the movable seat 818 is bolted to a first spring 819. One end of the first spring 819 away from the fixing seat two 820 is bolted to the outside of the movable seat 818. Moreover, two symmetrical wing plates 4 are bolted to the outside of the receiving frame 2. Two symmetrical round openings are formed in the wing plates 4, and a stabilizing seat 822 is bolted in each of the round openings. Insertion bolts 821 are inserted into the inner walls of the stabilizing seats 822, and the bottoms of the insertion bolts 821 are bolted to the upper side of the vehicle body 1;On the upper sides of multiple stabilizing seats 822, three notches 824 are equidistantly distributed in a circumferential manner. Locking rods 825 are slidably connected in the notches 824. Annular grooves 823 are formed on the insertion bolts 821, and the inner walls of the annular grooves 823 are clamped with the outer parts of the locking rods 825 on the same side. Short shafts are connected to the upper sides of the locking rods 825 through bolts. Rotating frames 826 are rotatably connected to the upper sides of the stabilizing seats 822 through bearings. Three curved grooves 827 are equidistantly distributed in a circumferential manner on the rotating frames 826, and the inner walls of the curved grooves 827 are slidably connected to the outer parts of the short shafts on the same side. Coil springs 828 are connected to the inner walls of the rotating frames 826 through bolts, and the ends of the coil springs 828 far from the rotating frames 826 are connected to the outer parts of the stabilizing seats 822 on the same side through bolts.;

[0029] Specifically, after the vehicle body 1 is vibrated, the vibration shock is transmitted to the movable plate 5 through the receiving frame 2, causing the movable plate 5 to be forced to descend. The descending movable plate 5 presses down, increasing the angle between the first rod 801 and the second rod 802, causing the movable block 805 to push the transmission piece 809 to move in the direction of the mounting plate 810, thereby compressing the first airbag 808. The compressed first airbag 808 transports air to the second airbag 815 through the air duct 813. The inflated second airbag 815 drives the movable seat 818 to slide in the rectangular groove 812. At the same time, under the extrusion of the knob 817 and the throat constriction tube 816, the cross-sectional area of the air duct 813 decreases, and the air flow velocity in the air duct 813 slows down, thereby offsetting the impact force. The moving movable seat 818 gradually compresses the first spring 819, causing the first spring 819 to buffer the impact force, so that the descending amplitude of the movable plate 5 gradually slows down and returns to its original position, finally absorbing and buffering the vibration.

[0030] In a specific application scenario, the energy absorption and shock absorption module 8 is mainly applicable to the energy absorption and shock absorption link in the energy absorption and shock absorption process. That is, the energy absorption and shock absorption module 8 utilizes the first airbag 808 and the second airbag 815 to conduct back-and-forth gas transmission under the resistance limitation of the throat constriction tube 816, gradually buffers the vibration by using the compressibility of air, and uses the first spring 819 and the magnetic sheet 811 to control the resilience of the movable block 805 and the movable plate 5, thereby greatly reducing the rebound reaction force released by the device after being vibrated. By locking the horizontal locking rod 825 with the annular groove 823, the influence of the vertical vibration on the device is weakened, avoiding the situation that the bolt is easily loosened under the influence of the axial force during conventional bolt connection. While ensuring the fixing effect, the stability of the connection between the device and the vehicle body 1 is improved.

[0031] Refer to Figure 7In a preferred embodiment, the exteriors of the plurality of mounting seats 901 are connected to the exteriors of the accommodating frame 2 by bolts, the upper sides of the mounting seats 901 are provided with convex seats 902, and the exteriors of the mounting seats 901 are connected to the covering frames 905 by bolts, the exteriors of the convex seats 902 are slidably connected to the inner walls of the covering frames 905 on the same side, and the convex seats 902 and the covering frames 905 are provided with openings; the bottoms of the plurality of mounting seats 901 are provided with slots, and movable rods 904 are slidably connected in the slots, and the upper sides of the movable rods 904 are connected to springs 903 by bolts, and the other ends of the springs 903 are connected to the top inner walls of the slots. Through bolt connection, the outside of the movable rod 904 is provided with a bevel block 906, the upper side of the bevel block 906 is rotatably connected to the bottom of the mounting seat 901 through a bearing, and the outside of the movable rod 904 is connected with a bevel block 907 through bolts, and the bevel block 907 is fitted with the side opposite to the bevel block 906; the outsides of multiple movable rods 904 are slidably connected with a connecting frame 908, the inner wall of the connecting frame 908 is fitted with the bottom of the bevel block 907, the outside of the connecting frame 908 is connected with a pin 909 through bolts, and the outside of the pin 909 is plugged into the inner wall of the hole on the cover frame 905 and the convex seat 902 on the same side.

[0032] Specifically, the isolation cover 3 is slightly deviated and fits with the upper side of the containing frame 2, and the isolation cover 3 is gently pushed so that the boss 902 on the isolation cover 3 can slide between the covering frame 905 and the mounting seat 901, and the inclined plane block 1 906 is rotated 180 degrees. The inclined plane block 1 906 and the inclined plane block 2 907, which originally keep the inclined planes in contact with each other, will be pushed downward by the inclined plane block 1 906, so that the movable rod 904 overcomes the elastic force of the spring 2 903 and descends, so that the connecting frame 908 drives the pin 909 to be inserted into the holes on the covering frame 905 and the boss 902, thereby fixing the isolation cover 3 on the containing frame 2.

[0033] In specific application scenarios, the quick disassembly and assembly module 9 is mainly suitable for the quick disassembly and assembly link in the quick disassembly and assembly process, that is, the quick disassembly and assembly module 9 uses the inclined surfaces on the inclined surface block 1 906 and the inclined surface block 2 907 to be staggered with each other, so that the pin 909 on the connecting frame 908 can quickly change its position on the protrusion 902, thereby realizing the locking and unlocking of the protrusion 902 by the pin 909. While ensuring the locking effect of the containing frame 2 on the isolation cover 3, the convenience of installation and disassembly is improved, the time for disassembly and installation by personnel is reduced, and the disassembly and assembly efficiency is improved.

[0034] Working principle: After sorting the automotive wire harness and placing it in the intervals formed by the partition plates 12 on the movable plate 5, the isolation cover 3 is slightly deviated and attached to the upper side of the accommodating frame 2. Then, gently push the isolation cover 3 so that the convex seat 902 on the isolation cover 3 can slide into the space between the covering frame 905 and the mounting seat 901. Rotate the inclined plane block one 906 by 180 degrees. The inclined plane block one 906 and the inclined plane block two 907, which originally maintained an inclined plane fit, the inclined plane block two 907 will be pushed downward by the inclined plane block one 906, causing the movable rod 904 to descend against the elastic force of the spring two 903. Thus, the connecting frame 908 drives the bolt 909 to insert into the holes in the covering frame 905 and the convex seat 902, thereby fixing the isolation cover 3 on the accommodating frame 2. Then, the lower fixing buckle 6 and the upper fixing buckle 7 can clamp the wire harness on the accommodating frame 2. After the vehicle body 1 is vibrated, the vibration shock is transmitted to the movable plate 5 through the accommodating frame 2, causing the movable plate 5 to be stressed and descend. The descending movable plate 5 presses downward, increasing the included angle between the rod body one 801 and the rod body two 802, causing the movable block 805 to push the transmission piece 809 to move in the direction of the mounting plate 810, thereby compressing the airbag one 808. The compressed airbag one 808 transports air to the airbag two 815 through the air duct 813. The inflated airbag two 815 drives the movable seat 818 to slide in the rectangular groove 812. At the same time, under the extrusion of the knob 817 and the throat constriction tube 816, the cross-sectional area of the air duct 813 decreases, and the air flow speed in the air duct 813 slows down, thereby offsetting the impact force. The moving movable seat 818 gradually compresses the spring one 819, and the spring one 819 buffers the impact force, so that the descending amplitude of the movable plate 5 gradually slows down and returns to its original position, finally absorbing and buffering the vibration.
