Description

Technical Field

[0001] This invention relates to the field of automotive wiring harness accessories technology, specifically to an automotive wiring harness fixing device. Background Technology

[0002] In automobiles, especially in new energy vehicles, there are many electrical wires and signal transmission lines. These wires are used to transmit current and signals in the car. Due to the space limitations of the car, these wires need to be gathered and arranged and fixed by fixing devices. Otherwise, messy wires can easily affect the installation of other parts in the car. At the same time, messy and unstable wires are prone to multi-directional irregular shaking under the vibration of the car.

[0003] Existing automotive wiring harness fixing devices generally use cable ties to gather the wiring and then secure them to the vehicle with tape or other fixing devices. However, this method has poor stability and is prone to falling off. Some devices use fixing brackets, which are fixed to the vehicle, reducing the risk of falling off. However, these still concentrate multiple wires together for fixing. This causes the fixing points of multiple wires to converge into a harness, resulting in the harness being subjected to hard compression for centralized fixing. This hard compression is applied manually and is not precise enough. Sometimes, excessive pressure can damage the harness, while insufficient pressure can cause the harness to loosen, leading to increased friction. At the same time, multiple wires outside the fixing point are in a state of outward expansion. When the vehicle vibrates, the fixing points of multiple wires are prone to mutual vibration, friction, and collision, which accelerates the friction and wear of the harness at the fixing point. In addition, when the vehicle is subjected to greater external force, its own vibration frequency is disrupted. At this time, the external force on the harness increases, and its vibration amplitude increases. The deviation from the vibration amplitude of the vehicle body causes relative displacement, which will lead to increased wear. Summary of the Invention

[0004] In view of the shortcomings of existing automotive wiring harness fixing devices mentioned in the background art during use, the present invention provides an automotive wiring harness fixing device with large spacing between multiple wires, preventing collision and friction between the wires, effectively protecting the wiring harness and avoiding friction damage.

[0005] This invention provides the following technical solution: an automotive wiring harness fixing device, comprising a wire divider wheel, on which evenly distributed insertion slots are formed, and signal wires are movably sleeved in the insertion slots. A hollow hole is formed at the center of the wire divider wheel, and symmetrical springs I are fixedly connected to the top of the inner wall of the hollow hole. A pressure plate is fixedly connected to the bottom end of the springs I. An elastic airbag is fixedly connected to the bottom of the inner wall of the hollow hole, and symmetrical one-way valves I are fixedly sleeved at both ends of the elastic airbag. The elastic airbag is located below the pressure plate, and the bottom of the elastic airbag... The part is fixedly connected with evenly distributed vent holes. An air distribution chamber is opened inside the dividing wheel. The air distribution chamber is connected to the elastic airbag through the vent holes. Evenly distributed movable grooves are opened inside the dividing wheel. Evenly distributed connecting pipes are fixedly sleeved inside the dividing wheel. Evenly distributed cover plates are movably sleeved on the outside of the dividing wheel. An airbag seat is fixedly connected to one side of the bottom end of the cover plate. An expansion airbag is fixedly connected to one end of the airbag seat. The expansion airbag is connected to the air distribution chamber through the connecting pipe. A blocking mechanism is provided on the airbag seat. An exhaust mechanism is provided on the dividing wheel.

[0006] Preferably, the two ends of the dividing wheel are fixedly connected to symmetrical fixing frames, and one end of the fixing frame is fixedly connected to the vehicle through a fixing device.

[0007] Preferably, the expansion airbag is filled with unsaturated air, and the connection between the connecting tube and the expansion airbag is close to the airbag seat.

[0008] Preferably, the blocking mechanism includes vent holes evenly distributed on the airbag seat, a piston movably connected inside the vent holes, a spring II fixedly connected to one end of the piston, and the other end of the spring II fixedly connected to the inner wall of the vent holes.

[0009] Preferably, the piston is T-shaped, with the end with the larger diameter value inside the expansion bladder and the end with the smaller diameter value inside the exhaust port.

[0010] Preferably, the exhaust mechanism includes pressure tubes evenly distributed and sleeved at one end of the opening of the wiring slot. The pressure tubes are hollow tubes and have dense holes.

[0011] Preferably, the expansion airbag is connected to the outside through an exhaust port, the exhaust port and the pressure tube are on the same circumference, the diameter of the exhaust port is larger than the diameter of the pressure tube, and the diameter of the spring II is larger than the diameter of the pressure tube.

[0012] The present invention has the following beneficial effects: 1. The cable slots can be opened by manually rotating the cover, allowing various cables to be directly inserted or removed, which improves the convenience of cable adjustment. At the same time, the wide distribution of multiple cable slots ensures that there is a certain distance between multiple cables, preventing direct contact and avoiding collision and friction problems caused by multiple cables being in direct contact or too close together during vibration.

[0013] 2. As the splitter wheel vibrates with the car, the pressure plate reciprocates under the drive of spring I, intermittently squeezing the elastic airbag. This causes the airbag to intermittently compress and expand. When compressed, the airbag forces internal gas into the air distribution chamber through the vent. When expanded, the airbag draws in outside air through one-way valve I (it also draws in gas from the air distribution chamber through the vent, but the amount drawn in is less than the amount discharged). This gradually increases the amount of gas in the air distribution chamber, which then flows into the expansion airbag through the connecting pipe. The expansion airbag then expands and fills the remaining space in the connector slot where the signal wire is inserted, completely encasing and compressing the signal wire for elastic fixation. This ensures that the signal wire remains fixed without excessive pressure, and its vibration frequency is consistent with that of the splitter wheel. This avoids damage caused by excessive pressure on the signal wire and wear caused by inconsistent vibration frequencies.

[0014] 3. When the car vibrates due to external influences, the frequency of the distributor wheel's vibration is out of sync with the car's own vibration frequency. This increases the amplitude of the pressure plate's bounce, causing the pressure plate to squeeze the fully inflated elastic airbag. The gas inside the elastic airbag acts as a force transmission medium, providing additional pressure to the signal cable and keeping it fixed to the distributor wheel. This prevents a sudden increase in the car's vibration amplitude, which could cause a deviation between the vibration amplitude of the signal cable and the distributor wheel, resulting in relative displacement between the signal cable and the connector slot, and ultimately, friction damage to the signal cable.

Detailed Implementation

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figures 1 to 3 A wiring harness fixing device for automobiles includes a wire splitter wheel 1. Symmetrical fixing brackets 18 are fixedly connected to both ends of the wire splitter wheel 1. One end of each fixing bracket 18 is fixedly connected to the automobile via a fixing device. The wire splitter wheel 1 has evenly distributed insertion slots 2, with signal wires 17 movably connected to the insertion slots 2. A hollow hole 3 is formed in the center of the wire splitter wheel 1. Symmetrical springs 14 are fixedly connected to the top of the inner wall of the hollow hole 3. A pressure plate 5 is fixedly connected to the bottom end of each spring 14. An elastic airbag 6 is fixedly connected to the bottom of the inner wall of the hollow hole 3. The airbag 6 is located below the pressure plate 5. When the engine vibrates, the entire car begins to vibrate, causing the pressure plate 5 to reciprocate under the action of the spring I4. This causes the pressure plate 5 to intermittently compress the airbag 6, resulting in intermittent compression deformation and expansion deformation of the airbag 6 due to its own elasticity. Symmetrical one-way valves I7 are fixedly sleeved at both ends of the airbag 6, allowing air from the outside to be drawn out through the one-way valves I7 when the airbag 6 inflates. The bottom of the airbag 6 is fixedly connected with evenly distributed vent holes 8.

[0019] See Figures 2 to 3 The dividing wheel 1 has an air distribution chamber 9, which is connected to the elastic airbag 6 through the vent hole 8. When the elastic airbag 6 is compressed, the gas inside can be forced into the air distribution chamber 9 through the vent hole 8, so that the amount of gas in the air distribution chamber 9 gradually increases. The dividing wheel 1 has evenly distributed movable grooves 10. Evenly distributed connecting pipes 11 are fixedly sleeved inside the dividing wheel 1. One end of the opening of the insertion groove 2 is fixedly sleeved with evenly distributed pressure pipes 12. The pressure pipes 12 are hollow pipes and have dense holes. After the pressure pipes 12 push open the piston 152, the relatively high pressure air in the expanding airbag 16 can enter the exhaust hole 15 and be discharged into the pressure pipes 12 through the dense holes on the pressure pipes 12, and then discharged from the pressure pipes 12.

[0020] See Figures 1 to 2, Figures 4 to 6 The outer side of the splitter wheel 1 is movably fitted with evenly distributed cover plates 13. One side of the bottom end of the cover plate 13 is fixedly connected to an airbag seat 14. One end of the airbag seat 14 is fixedly connected to an expansion airbag 16. The expansion airbag 16 is connected to the air distribution chamber 9 through a connecting pipe 11. When the elastic airbag 6 is compressed, the gas in the elastic airbag 6 will be forced into the air distribution chamber 9 through the vent hole 8 and then into the expansion airbag 16 through the connecting pipe 11, causing the expansion airbag 16 to expand. The expansion airbag 16 is filled with unsaturated air, which reduces the time for the expansion airbag 16 to draw in air and can fill the space of the plug slot 2 in the shortest time to complete the elastic fixation of the signal line 17. The connection between the connecting pipe 11 and the expansion airbag 16 is close to the airbag seat 14, so that when the cover plate 13 drives the expansion airbag 16 to rotate, the connecting pipe 11 has enough movement distance to maintain normal air supply.

[0021] See Figure 6 The airbag seat 14 has evenly distributed exhaust holes 15. The expansion airbag 16 is connected to the outside through the exhaust holes 15. The exhaust holes 15 and the pressure tube 12 are on the same circumference. The diameter of the exhaust holes 15 is larger than the diameter of the pressure tube 12. A piston 152 is movably connected inside the exhaust holes 15. The piston 152 is T-shaped. The end of the piston 152 with a larger diameter is inside the expansion airbag 16, and the end with a smaller diameter is inside the exhaust holes 15, so that the piston 152 can block the exhaust holes 15 and prevent gas leakage from the expansion airbag 16. A spring II 151 is fixedly connected to one end of the piston 152. The other end of the spring II 151 is fixedly connected to the inner wall of the exhaust hole 15. The diameter of the spring II 151 is larger than the diameter of the pressure tube 12, so that the pressure tube 12 can be inserted into the exhaust hole 15 and push the piston 152.

[0022] The method of using (working principle) of this invention is as follows: First, the mounting bracket 18 is fixed to the car using a fixing device (bolts, welding, etc.). Then, the cover plate 13 is manually rotated to open the wiring slot 2. During this process, the gas in the expansion airbag 16 located in the wiring slot 2 is gradually transferred to the expansion airbag 16 located in the movable slot 10 by the compression of the splitter wheel 1 and the cover plate 13. Then, the signal wire 17 is pressed into the wiring slot 2. Next, the cover plate 13 is manually rotated to cover the wiring slot 2 again. During this process, the gas in the expansion airbag 16 located in the movable slot 10 is gradually transferred to the expansion airbag 16 located in the wiring slot 2 by the compression of the splitter wheel 1 and the cover plate 13. Then, when the car starts, the engine vibration causes the entire car to vibrate, causing the pressure plate 5 to reciprocate under the action of spring I4. This intermittently compresses the elastic airbag 6, causing it to undergo intermittent compression and expansion deformation due to its own elasticity. When the elastic airbag 6 is compressed, the gas inside it is forced into the air distribution chamber 9 through the vent 8 and into the expansion airbag 16 through the connecting pipe 11, causing the expansion airbag 16 to inflate. When the elastic airbag 6 inflates, it draws air from the air distribution chamber 9 through the vent 8 and simultaneously draws in outside air through the one-way valve I7. This ensures that the amount drawn from the air distribution chamber 9 is less than the amount introduced, thus continuously increasing the gas content in the air distribution chamber 9 and the expansion airbag 16, causing the expansion airbag 16 to continuously inflate and fill the wiring slot. The remaining space within 2 allows the expansion airbag 16 and the wiring slot 2 to elastically fix the signal line 17, making the vibration frequency of the signal line 17 consistent with that of the splitter wheel 1. At this time, the elastic airbag 6 is filled with air, which reduces its compression ratio and makes it impossible to open the one-way valve I7. This causes the elastic airbag 6 to stop reciprocating. The pressure plate 5 is affected by the elastic airbag 6, and its bounce amplitude weakens. Then, when the car is affected by external force and breaks its current vibration frequency, the vibration amplitude of the pressure plate 5 increases again, causing the pressure plate 5 to forcefully press the elastic airbag 6. Under the premise of small compression deformation, the elastic airbag 6 transmits pressure to the expansion airbag 16 through the internal gas, which increases the pressure of the expansion airbag 16 on the signal line 17, making the signal line 17 close to the wiring slot 2, and keeping the signal line 17 vibrating at the same frequency as the splitter wheel 1. Finally, when it is necessary to remove the signal line 17, manually rotate the cover plate 13 to open the wire insertion slot 2 again. At this time, part of the expansion airbag 16 gradually enters the movable slot 10, so that the gas in the expansion airbag 16 located in the wire insertion slot 2 is squeezed by the wire separator wheel 1 and the cover plate 13 and gradually transferred to the expansion airbag 16 located in the movable slot 10. When the pressure tube 12 is inserted into the exhaust hole 15, it will push the piston 152 to stretch the spring II 151, so that the exhaust hole 15 is connected to the inside of the expansion airbag 16, and the high pressure air inside the expansion airbag 16 can be discharged through the exhaust hole 15 and the pressure tube 12.
