Description

Technical Field

[0001] The present invention relates to an adjustable bracket for installing an automobile wiring harness, and in particular to an adjustable bracket for installing an automobile wiring harness applied in the bracket field. Background Art

[0002] The automotive wiring harness is the network backbone of the vehicle's electrical circuits. Without it, there would be no automotive circuit. Modern cars have numerous wiring harnesses, and the electronic control system is closely connected to them. Therefore, during installation, brackets are necessary to secure the harnesses to prevent friction or breakage.

[0003] For example, the publication number CN113541054B is a type of automobile wiring harness fixing bracket capable of synchronously fixing multiple wiring harnesses, and the publication number CN105449603B is a type of automobile wiring harness bracket, both of which introduce brackets for fixing wiring harnesses and can also achieve bending and fixing of wiring harnesses.

[0004] Although the brackets in the existing technology can meet the general installation requirements of the wiring harness, the working environment faced by the automotive wiring harness during the operation of the vehicle is relatively complex. It is necessary not only to prevent the wiring harnesses from rubbing against each other, but also to prevent the wiring harnesses from overheating. The existing brackets only play a simple fixing role. First, they cannot adapt to wiring harnesses of different specifications. Second, they cannot dissipate heat for the wiring harnesses, especially for wiring harnesses close to the engine, whose working environment temperature is higher than that of wiring harnesses in other positions. In addition, in the high temperature environment in summer, the stability of the wiring harness is difficult to guarantee. Third, the wiring harness connectors cannot be fixed, resulting in the connection of the wiring harness easily falling off. Summary of the Invention

[0005] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is how to promptly dissipate heat from the automotive wiring harness to prevent it from being damaged in a high-temperature working environment.

[0006] In order to solve the above problems, the present invention provides an adjustable bracket for installing an automobile wiring harness, comprising a fixed bracket, wherein both upper and lower ends of the fixed bracket are fixedly connected to mounting plates, and a slide groove is provided on the side wall of the fixed bracket, wherein a plurality of adjustment seats distributed up and down are connected in a damping sliding manner in the slide groove, and the upper end side wall of the adjustment seat is fixedly connected to the fixed seat, the upper end side wall of the fixed seat is fixedly connected to a lower bundle tube, and the side of the lower bundle tube close to the fixed bracket is rotatably connected to an upper bundle tube with the same structure as the lower bundle tube, the side walls of the lower bundle tube and the upper bundle tube on the opposite side are fixedly connected to a wire covering film, and the side walls of the lower bundle tube and the upper bundle tube away from the fixed bracket are fixedly connected to mutually matching buckle locks;

[0007] The wire covering membrane includes a flexible middle membrane, and an elastic side membrane is fixedly connected between the upper end of the flexible middle membrane and the inner wall of the lower bundle tube. The flexible middle membrane, the elastic side membrane and the lower bundle tube together form a closed space, and the closed space is filled with flowing liquid.

[0008] In the above-mentioned adjustable bracket for installing automotive wiring harnesses, multiple pairs of lower harness tubes and upper harness tubes are used to separately fix the wiring harnesses, effectively preventing damage caused by friction between the wiring harnesses. The elasticity and tight wrapping properties of the wire covering film are used to fix the wiring harnesses or wiring harness connectors, which can adapt to wiring harnesses and wiring harness connectors of different specifications. In addition, the idle space of the bracket is used to absorb the heat of the wiring harnesses and wiring harness connectors, thereby achieving efficient heat dissipation.

[0009] As a further improvement of the present application, a plurality of equally spaced and circumferentially distributed thermally deformable bands are fixedly connected between the inner wall of the flexible middle membrane and the inner wall of the lower bundle tube, and the thermally deformable bands are made of shape memory material.

[0010] As a further improvement of the present application, a heat dissipation cavity is opened on the inner wall of the fixed bracket, and the inside of the heat dissipation cavity is also filled with flowing liquid. Two hoses are fixedly connected between the lower bundle tube and the upper bundle tube and the fixed bracket. Water pumps connected to the two hoses are installed on both sides of the inside of the heat dissipation cavity, and the inner walls of the lower bundle tube and the upper bundle tube are fixedly inlaid with flow self-regulating tubes connected to the hoses and the enclosed space.

[0011] As a further improvement of the present application, two water pumps and two hoses form a circulation loop, the filling volume of the flowing liquid inside the enclosed space and the heat dissipation cavity is 70%-80%, and the flowing liquid is a coolant. The side wall of the fixed bracket away from the adjustment seat is also fixedly embedded with a semiconductor refrigeration plate, and the cooling surface of the semiconductor refrigeration plate extends to the inside of the heat dissipation cavity.

[0012] As another improvement of the present application, a heat-conducting belt coaxial with the lower bundle tube is fixedly embedded in the inner wall of the lower bundle tube, and the heat-conducting belt is fixedly connected to the thermally deformable belt through multiple heat-conducting wires, and one end of the heat-conducting belt passes through the interior of the flow self-regulating tube.

[0013] As another improved supplement to the present application, the flow self-regulating tube includes two layers of elastic tube bodies, an inner layer and an outer layer, and an elastic tube edge is fixedly connected between the side walls of the two layers of elastic tube bodies. A thermally deformable net is filled between the two layers of elastic tube bodies, and the heat conductive tape is fixedly connected to the thermally deformable net.

[0014] As another improved supplement of the present application, a pressure sensor is also installed on the inner wall of the elastic tube body located in the outer layer, and the pressure sensor is connected to the water pump and the semiconductor refrigeration plate through the control processor.

[0015] As another improvement of the present application, both ends of the lower bundle tube are fixedly connected with a guide half-tube, the guide half-tube includes a flexible tube body, and the inner wall of the flexible tube body is fixedly inlaid with a plurality of randomly curved skeletons distributed at equal intervals. The inner walls on both sides of the upper end of the flexible tube body are provided with cavities, and a plurality of equally spaced limiting balls are placed inside the cavity, and there is magnetic repulsion between adjacent limiting balls, and an elastic limiting rope is also fixedly connected between the adjacent limiting balls.

[0016] In summary, by setting up multiple pairs of lower bundle tubes and upper bundle tubes to separate and fix the wire harnesses, the wire harnesses are effectively prevented from being damaged by friction between each other, and the wrapping properties of the wire covering film are used to fix the wire harnesses or wire harness connectors. The wire covering film can be adaptively adjusted to achieve the fixation of wire harnesses and wire harness connectors of different specifications, which is more adaptable. In addition, a heat-absorbing structure is set inside the lower bundle tube and the upper bundle tube to absorb the heat of the wire harness and the wire harness connector, and transfer the heat to the inside of the fixed bracket for heat dissipation, effectively preventing the wire harness and the wire harness connector from melting in a high temperature environment and affecting the safety of the car, and can adaptively adjust the heat dissipation according to the temperature of each group of wire harnesses or each wire harness connector, thereby effectively improving the heat dissipation effect.

DETAILED DESCRIPTION

[0029] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0030] The first implementation method:

[0031] like Figure 1 、 2 As shown, an adjustable bracket for installing an automobile wiring harness includes a fixed bracket 1, the upper and lower ends of the fixed bracket 1 are fixedly connected to a mounting plate 101, and the side wall of the fixed bracket 1 is provided with a slide groove 102, and a plurality of adjustment seats 2 distributed up and down are connected in a damping sliding manner in the slide groove 102, and the upper end side wall of the adjustment seat 2 is fixedly connected to a fixed seat 3, the upper end side wall of the fixed seat 3 is fixedly connected to a lower beam tube 4, and the side of the lower beam tube 4 close to the fixed bracket 1 is rotatably connected to an upper beam tube 5 with the same structure as the lower beam tube 4, the side walls of the lower beam tube 4 and the upper beam tube 5 on the opposite side are fixedly connected to a wire covering film 6, and the side walls of the lower beam tube 4 and the upper beam tube 5 away from the fixed bracket 1 are fixedly connected to mutually matching The buckle lock 7 (which is a prior art and the specific structure is not described here) is used. When in use, the fixing bracket 1 is fixed to the automobile bracket with a bolt passing through the mounting plate 101, and then the multiple groups are divided into a single group. Each group of wiring harnesses is placed on the lower harness tube 4, and then the upper harness tube 5 is closed and the lower harness tube 4 and the upper harness tube 5 are locked together with the buckle lock 7, so as to achieve the fixation of the wiring harness. Similarly, the wiring harness connector can also be fixed between the lower harness tube 4 and the upper harness tube 5. The wire covering film 6 wraps the wiring harness or the wiring harness connector, effectively preventing the wiring harness from moving back and forth and being worn and damaged. Moreover, the wire covering film 6 can rely on its own elasticity to tightly wrap the wiring harness or the wiring harness connector, so that wiring harnesses or wiring harness connectors of different specifications can be fixed;

[0032] like Figure 3As shown, the wire covering film 6 includes a flexible middle film 601 (preferably made of silicone, but other materials can also be selected according to actual needs), and an elastic side film 602 (preferably made of rubber, but other materials can also be selected according to actual needs) is fixedly connected between the upper end of the flexible middle film 601 and the inner wall of the lower bundle tube 4. The flexible middle film 601, the elastic side film 602 and the lower bundle tube 4 together form a closed space, and the closed space is filled with a flowing liquid. In the process of the wire covering film 6 wrapping the wire harness or the wire harness connector, the fluidity of the flowing liquid is utilized to enable the wire covering film 6 to tightly wrap the wire harness or the wire harness connector to prevent the wire harness or the wire harness connector from moving back and forth during the driving of the vehicle and being damaged by friction. In addition, the flexible middle film 601 can fit tightly with wire harnesses of different thicknesses or wire harness connectors of different sizes, thereby effectively improving the adaptability of the bracket.

[0033] like Figure 3 As shown, a plurality of equally spaced and surrounding thermo-deformable bands 8 are fixedly connected between the inner wall of the flexible middle membrane 601 and the inner wall of the lower bundle tube 4, and the thermo-deformable bands 8 are made of shape memory material (shape memory polymer material is preferred, and other materials can also be selected according to actual needs). The flexible middle membrane 601 can transfer the heat of the wiring harness or the wiring harness connector to the thermo-deformable band 8. When the heat of the wiring harness or the wiring harness connector exceeds the temperature at which the thermo-deformable band 8 can be deformed, the thermo-deformable band 8 stretches and deforms, so that the wire covering film 6 can wrap the wiring harness or the wiring harness connector more tightly to prevent the lower bundle tube 4 and the upper bundle tube 5 from expanding due to heat and causing a large gap and losing the fixing effect. In addition, the deformation temperature of the thermo-deformable band 8 is selected according to the safe operating temperature of the wiring harness and the wiring harness connector. It is determined according to actual needs during actual use and will not be repeated here.

[0034] like Figure 3 、 5As shown, a heat dissipation cavity 103 is provided on the inner wall of the fixed bracket 1, and the heat dissipation cavity 103 is also filled with flowing liquid. Two hoses 10 are fixedly connected between the lower bundle tube 4 and the upper bundle tube 5 and the fixed bracket 1. Water pumps 11 connected to the two hoses 10 are respectively installed on both sides of the interior of the heat dissipation cavity 103 (the specific model is selected according to actual needs and is not described here), and the inner walls of the lower bundle tube 4 and the upper bundle tube 5 are fixedly inlaid with flow self-regulating tubes 13 connected to the hoses 10 and the closed space. The two water pumps 11 and the two hoses 10 form a circulation loop. The flowing liquid filling volume of the closed space and the heat dissipation cavity 103 is 70%-80%, and the flowing liquid is a coolant. The coolant is preferably the same liquid as the engine coolant to avoid freezing at low temperatures in winter. A semiconductor refrigeration plate 12 is also fixedly inlaid on the side wall of the fixed bracket 1 away from the adjustment seat 2 (the specific model is selected according to actual needs and is not described here), and the cooling surface of the semiconductor refrigeration plate 12 extends to the interior of the heat dissipation cavity 103, using a fixed The idle space of the bracket 1 is used to dissipate heat for the wiring harness or wiring harness connector. During operation, the flexible middle membrane 601 transfers the heat of the wiring harness or wiring harness connector to the thermally deformable belt 8, and the thermally deformable belt 8 then transfers the heat to the flowing liquid in the closed space. At the same time, the water pump 11 and the semiconductor refrigeration plate 12 are started, and the two water pumps 11 cooperate with each other, one to pump liquid and the other to deliver liquid, so that the flowing liquid circulates in the heat dissipation cavity 103 and the closed space through the two hoses 10. One of the water pumps 11 pumps the flowing liquid in the closed space into the heat dissipation cavity 103, and the semiconductor refrigeration plate 12 cools the flowing liquid to cool it down. The cooled flowing liquid is then transported back to the closed space by the other water pump 11, thereby realizing indirect heat dissipation of the wiring harness or wiring harness connector. Compared with the existing technology, it can effectively prevent the wiring harness or wiring harness connector from melting in a high temperature environment. In addition, in order to leave redundant space for the flowing liquid, so as to avoid the wire covering membrane 6 and the hose 10 from bursting due to the squeezing force when fixing the wiring harness or wiring harness connector, the filling amount of the flowing liquid cannot be saturated.

[0035] This embodiment separates and fixes the wiring harnesses by setting up multiple pairs of lower harness tubes 4 and upper harness tubes 5, effectively preventing the wiring harnesses from being damaged by friction with each other, and uses the wrapping properties of the wire covering film 6 to fix the wiring harnesses or wiring harness connectors. The wire covering film 6 can be adaptively adjusted to achieve the fixation of wiring harnesses and wiring harness connectors of different specifications, with stronger adaptability. A heat-absorbing structure is also set inside the lower harness tube 4 and the upper harness tube 5 to absorb the heat of the wiring harness and wiring harness connector, and transfer the heat to the inside of the fixing bracket 1 for dissipation, effectively preventing the wiring harness and wiring harness connector from melting in a high temperature environment and affecting the safety of the vehicle.

[0036] The second implementation method:

[0037] This embodiment optimizes the heat dissipation structure based on the first embodiment, thereby adaptively adjusting the heat dissipation according to the heating conditions of each group of wiring harnesses, while the rest of the structure remains the same as the first embodiment.

[0038] like Figure 4 、 6 As shown, the inner wall of the lower bundle tube 4 is fixedly inlaid with a conductive belt 9 which is concentric with the lower bundle tube 4, and the conductive belt 9 is fixedly connected to the thermally deformable belt 8 through a plurality of heat-conducting wires. One end of the conductive belt 9 passes through the interior of the flow self-regulating tube 13. The flow self-regulating tube 13 includes an inner and outer two-layer elastic tube body 1301 (preferably a polyurethane elastic material, and other materials can also be selected according to actual needs), and an elastic tube edge 1302 (preferably a rubber material, and other materials can also be selected according to actual needs) is fixedly connected between the side walls of the two layers of elastic tube body 1301, and a thermally deformable mesh 1303 (preferably a shape memory polymer material, and other materials can also be selected according to actual needs) is filled between the two layers of elastic tube body 1301. The specific thermal deformation temperature is selected according to actual needs and will not be described here), and the conductive belt 9 is fixedly connected to the thermo-deformable net 1303. The thermo-deformable belt 8 transfers heat to the conductive belt 9 at the same time, and the conductive belt 9 transfers heat to the thermo-deformable net 1303. When the temperature of the wiring harness or wiring harness connector is too high to dissipate heat in time, when the temperature exceeds the deformation temperature of the thermo-deformable net 1303, the thermo-deformable net 1303 shrinks and deforms, so that the aperture of the flow self-regulating tube 13 is increased, thereby increasing the flow rate and the amount of flowing liquid entering and exiting the wire covering film 6, thereby effectively improving the heat dissipation effect. In this way, dynamic heat dissipation adjustment can be performed according to the actual heating conditions of each group of wiring harnesses or wiring harness connectors;

[0039] like Figure 6 As shown, a pressure sensor 1304 is further installed on the inner wall of the elastic tube body 1301 located in the outer layer, and the pressure sensor 1304 is connected to the water pump 11 and the semiconductor cooling plate 12 through a control processor (the specific model is selected according to actual needs and is not described here). When the thermo-deformable network 1303 contracts and deforms, the pressure sensor 1304 is subjected to pressure and generates an electrical signal. The pressure sensor 1304 then transmits the electrical signal to the water pump 11 and the semiconductor cooling plate 12. On the one hand, the power of the water pump 11 is increased to increase the flow rate of the flowing liquid and accelerate the heat transfer efficiency. On the other hand, the current of the semiconductor cooling plate 12 is increased to improve the cooling effect, thereby effectively improving the heat dissipation effect of the wiring harness and the wiring harness connector.

[0040] like Figure 7 、 8As shown in Figures 9 and 10, both ends of the lower bundle tube 4 are fixedly connected with a guide half-tube 14, and the guide half-tube 14 includes a flexible tube body 1401, and the inner wall of the flexible tube body 1401 is fixedly inlaid with a plurality of randomly bent skeletons 1402 distributed around at equal intervals (preferably aluminum alloy material, and other materials can also be selected according to actual needs), and the inner walls on both sides of the upper end of the flexible tube body 1401 are provided with cavities, and a plurality of equally spaced limiting balls 15 are placed inside the cavities, and the adjacent two limiting balls 15 are magnetically repelled, and the adjacent two limiting balls 15 are 5 are arranged relative to each other, and an elastic limiting rope 16 (preferably made of rubber, but other materials can also be selected according to actual needs) is fixedly connected between two adjacent limiting balls 15. During actual installation, the direction of each set of wire harnesses is different. Therefore, a guide half-tube 14 is added to guide the wire harnesses. During guidance, the free bending property of the free bending skeleton 1402 is used to adjust the direction of the wire harnesses. Moreover, when the bending angle is too large, the magnetic repulsion between the two adjacent limiting balls 15 can prevent the wire harnesses from being excessively bent, thereby protecting the wire harnesses.

[0041] In view of current actual needs, the protection scope of the above-mentioned implementation mode adopted in this application is not limited to this. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the protection scope of the present invention.
