Description

Technical Field

[0001] The utility model is applied to the technical field of wire harness fixing, and particularly relates to a combined fixing structure for high-voltage wire harnesses. Background Technique

[0002] There are many vehicle pipelines in pure electric buses, mainly including brake air pipes, power steering oil pipes, cooling water pipes for batteries and motor electronic controls, air-conditioning refrigeration pipes, water heating pipes, as well as high-voltage wire harnesses and low-voltage wire harnesses, etc. In the vehicle design, not only these complex pipelines need to be designed and arranged well in terms of space installation, but also problems such as heat insulation and electromagnetic interference between them need to be considered. For the design and arrangement of high-voltage wire harnesses, the safety of high-voltage electricity should also be ensured. In order to reasonably install and fix high-voltage wire harnesses, the commonly used method at present is to weld or install various wire harness brackets on the vehicle body frame, and then bundle the high-voltage wire harnesses on the wire harness brackets with D-type clamps or nylon cable ties. This method of fixing high-voltage wire harnesses can ensure firm fixation, but for the bundling of multiple wire harnesses, it lacks aesthetics, and there are problems with inconvenient installation and fixation of wire harnesses in narrow spaces. Often, vehicle manufacturers lay out and install high-voltage wire harnesses flat by using wire harness clamping plates, which increases the aesthetics of the high-voltage wire harness layout and can also ensure simplicity and beauty when realizing the layered and staggered layout of high-voltage wire harnesses. The existing wire harness fixing structures with D-type clamps and cable ties generally require welding and adding metal wire harness brackets to the vehicle body frame. D-type clamps need to use bolt and nut combinations for fixation. In order to improve production efficiency, electric or pneumatic tools are often used, so sufficient installation space must be left at each fixing point. In addition, the wire diameters of the high-voltage wire harnesses of the whole vehicle are different, and the number of wire harnesses arranged and bundled together is different. Workers generally need to frequently replace different D-type clamps to adapt to the wire harness fixing requirements at different positions before fixing the wire harnesses. Therefore, this wire harness fixing method has problems such as inconvenient installation and unbeautiful wire harness layout. If a combined fixing structure for high-voltage wire harnesses with a simple structure, convenient installation, accurate positioning, and capable of multi-module combination according to the arrangement of high-voltage wires can be designed, the above problems can be solved.

[0024] As Figures 1 to 10 shown, in this embodiment, the utility model includes a frame square tube 1, a fixed buckle 2, an L-shaped bracket 3, a single-wire bracket 4 and a three-wire bracket 5. The fixed buckle 2 includes a buckle main body 21 and a buckle elastic piece 22. The buckle elastic piece 22 is arranged at the lower end of the buckle main body 21. A buckle connection head 23 is arranged at the upper end of the buckle main body 21. The frame square tube 1 is provided with a plurality of buckle fixing holes 6. A plurality of the fixed buckles 2 are connected to the plurality of buckle fixing holes 6 through the buckle elastic pieces 22. A plurality of high-voltage wires 7 are respectively matched with the fixed buckle 2 through the L-shaped bracket 3, the single-wire bracket 4 and the three-wire bracket 5. Thus, it can be seen that the frame square tube 1 is provided with a plurality of equidistant buckle fixing holes 6, so that a plurality of the fixed buckles 2 can be arranged on the frame square tube 1 at equal intervals, installed according to the number of wire harnesses, and the installation operation is more convenient through the buckle elastic pieces 22. The L-shaped bracket 3, the single-wire bracket 4 and the three-wire bracket 5 can all be adapted to the buckle connection head 23, and the L-shaped bracket 3, the single-wire bracket 4 and the three-wire bracket 5 can be connected to each other to realize multi-directional and multi-combination fixing of a plurality of the high-voltage wires 7.

[0025] As Figure 1 and 10 shown, in this embodiment, the L-shaped bracket 3 includes a bracket main body part 31 and a bracket deflection part 32. An intermediate connection seat 33 is arranged at the lower end of the bracket main body part 31. A main body connection seat 34 is arranged at the end of the bracket main body part 31. A deflection connection seat 35 is arranged at the end of the bracket deflection part 32. The intermediate connection seat 33, the main body connection seat 34 and the deflection connection seat 35 can all be matched with the buckle connection head 23, the single-wire bracket 4 and the three-wire bracket 5. Thus, it can be seen that the angle between the bracket main body part 31 and the bracket deflection part 32 is 90°. When there is a situation where a plurality of the high-voltage wires 7 are stacked, the L-shaped bracket 3 can separate the brackets by a certain distance to prevent the brackets from being concentratedly connected and causing deformation due to the large local weight.

[0026] As Figure 4 and Figure 5As shown, in this embodiment, a single-wire profiling groove 41 is provided in the middle of the single-wire bracket 4. The single-wire profiling groove 41 is in limit fit with the high-voltage wire 7. Single-wire connection seats 42 are provided on one side and the bottom of the single-wire bracket 4. The single-wire connection seats 42 are in cooperation with the snap connection heads 23. A single-wire bracket connection head 43 is further provided on the other side of the single-wire bracket 4. The single-wire bracket connection head 43 is in cooperation with the L-shaped bracket 3. Thus, it can be seen that the single-wire profiling groove 41 is an open design and can quickly snap into the high-voltage wire. A number of the single-wire profiling grooves 41 and the snap connection heads 23 can be combined and connected with each bracket.

[0027] As Figure 4 and Figure 5 As shown, in this embodiment, a rotation positioning groove 44 is provided at one end of the single-wire bracket 4. A wire harness lock 45 is in rotational fit with the rotation positioning groove 44. The wire harness lock 45 and the single-wire profiling groove 41 are in cooperation with the high-voltage wire 7. Thus, it can be seen that the wire harness lock 45 can lock and unlock the high-voltage wire 7 by rotation, preventing the wire harness from falling off during the installation process.

[0028] As Figures 6 to 8 As shown, in this embodiment, the three-wire bracket 5 includes a first bracket 8 and a second bracket 9. Three groups of first semi-circular grooves 81 are provided at the upper end of the first bracket 8. A first bracket connection head 82 is provided on the high-position side at the upper end of the first bracket 8. A first connection seat 83 is provided on the low-position side at the upper end of the first bracket 8. Three groups of second semi-circular grooves 91 are provided at the upper end of the second bracket 9. A second bracket connection head 92 is provided on the high-position side at the upper end of the second bracket 9. A second connection seat 93 is provided on the low-position side at the upper end of the second bracket 9. The first bracket connection head 82 and the first connection seat 83 are respectively in cooperation with the second connection seat 93 and the second bracket connection head 92. The high-voltage wire 7 is respectively in cooperation with the first semi-circular grooves 81 and the second semi-circular grooves 91. Thus, it can be seen that the first bracket 8 and the second bracket 9 are connected to each other and can fix at most three groups of the high-voltage wires 7, and can be connected with each bracket in multiple directions and at multiple angles.

[0029] As Figures 6 to 8 As shown, in this embodiment, a number of third bracket connection seats 84 are provided at the lower end of the first bracket 8. A number of third bracket connection heads 94 are provided at the lower end of the second bracket 9. Two groups of the three-wire brackets 5 are connected through the third bracket connection seats 84 and the third bracket connection heads 94. Thus, it can be seen that two groups of the three-wire brackets 5 can be stacked and connected through the number of third bracket connection seats 84 and the number of third bracket connection heads 94 to adapt to the situation of fixing multiple layers of closely arranged high-voltage wires 7.

[0030] As Figures 6 to 8As shown, in this embodiment, a fourth bracket connecting seat 85 is provided on the outer side of the high-position end of the first bracket 8, and a fourth bracket connecting head 95 is provided on the outer side of the high-position end of the second bracket. The two groups of three-wire brackets 5 are horizontally connected through the fourth bracket connecting seat 85 and the fourth bracket connecting head 95. Thus, it can be seen that the two groups of three-wire brackets 5 can be horizontally connected through the fourth bracket connecting seat 85 and the fourth bracket connecting head 95 to adapt to the situation of fixing multiple groups of closely arranged high-voltage wires 7 in a single layer.

[0031] As Figures 1 to 3 shown, in this embodiment, a cable tie hole 24 is provided in the middle of the buckle body 21, and several high-voltage wires 7 are connected to the buckle connecting head 23 through cable ties 25. Thus, it can be seen that when fixing an independent group of high-voltage wires 7, the high-voltage wires 7 can be fixed to the buckle connecting head 23 through the cable ties 25.

[0032] As Figures 1 to 10 shown, in this embodiment, several L-shaped brackets 3, several single-wire brackets 4, and several three-wire brackets 5 are cooperatively fixed on several fixing buckles 2. Thus, it can be seen that the connecting seats and connecting heads on the L-shaped brackets 3, the single-wire brackets 4, and the three-wire brackets 5 have the same size, can realize multi-directional connection between components, have more combination methods, can adapt to a complex wiring environment, and can realize horizontal connection or vertical connection.

[0033] Working principle of the present utility model: Before connecting several high-voltage wires 7, several fixing buckles 2 are installed on several buckle fixing holes 6 according to the number of the high-voltage wires 7, and several L-shaped brackets 3, several single-wire brackets 4, and several three-wire brackets 5 are combined and connected to the vehicle frame square tube 1 according to the positions, heights, and relative distances of several high-voltage wires. During the process of combined connection, several high-voltage wires 7 are fixed synchronously, so as to realize the combined fixation of several high-voltage wire harnesses.

[0034] Although the embodiments of the present utility model are described with actual solutions, they do not constitute a limitation to the meaning of the present utility model. For those skilled in the art, modifications to its implementation solutions according to this specification and combinations with other solutions are obvious.
