Description

Technical Field

[0001] This utility model belongs to the field of wire harness fixing technology, specifically relating to a wire harness fixing device and an automobile. Background Technology

[0002] With the support for new energy technologies, new energy vehicles are developing rapidly, and new energy mining trucks have emerged as a result. This has brought about a significant increase in the need for secure wiring harnesses. As a core component of automotive circuitry, automotive wiring harnesses perform crucial functions such as power transmission, signal transmission, and device connection, and are widely distributed in areas such as the engine compartment, chassis, passenger compartment, and trunk. The reliability of wiring harness installation directly affects the safety, durability, and performance of a vehicle.

[0003] On new energy mining trucks, due to the harsh environment of the mining area, there are bumps and a lot of dust, and some areas are indeed in continuous rain. If the high-voltage wiring harness is not secured, the connection may become loose due to the bumps, dust, and rain as the vehicle runs, leading to water and dust ingress, which in turn can cause vehicle malfunctions and greatly affect work efficiency. At present, the high-voltage wiring harness is basically secured by cable ties and clips.

[0004] However, cable ties are prone to wear and have poor reliability, while clips are not universally compatible and can only secure wire harnesses with similar diameters, resulting in poor adaptability. Utility Model Content

[0005] To address the shortcomings of existing technologies, a wire harness fixing device is provided to solve the problem of poor wire harness fixing effect.

[0006] On the one hand, the technical solution of this utility model to solve the above-mentioned technical problems is as follows: a wire harness fixing device, comprising: A fixed base, wherein a plurality of baffles are spaced apart along a first direction, and the plurality of baffles are divided on the fixed base to form a plurality of wire-passing grooves, wherein at least one first through hole is provided in the wire-passing grooves, and a second through hole is provided on the baffles corresponding to the first through hole; A binding strap is inserted into the first through hole and the second through hole to bind and fix the wire bundle located in the wire groove; The first through hole is a strip-shaped through hole arranged along the first direction.

[0007] Compared with existing technologies, the above technical solutions have the following beneficial effects: The cable tie is passed through the two through holes, which allows the cable tie to fix the wire bundle located in the wire passage groove, thus playing a fixing role. The second through hole is set as a strip hole, so that the cable tie passing through the second through hole can tightly and securely tie wire bundles of different diameters and different numbers.

[0008] Based on the above technical solution, the embodiments of this application can be further improved as follows: In one embodiment, the binding force-bearing surface at the bottom of the fixing base, located between the first through hole and the second through hole, is an arc-shaped force-bearing surface.

[0009] When the strapping needs to be tightened after passing through the first and second through holes, the part in contact with the inner side of the strapping forms the strapping force-bearing surface. Reducing the sharp protrusions of this force-bearing surface can prevent the strapping from breaking during long-term vibration.

[0010] In one embodiment, the bottom of the fixing base is provided with a guide portion, the guide portion covers the force-bearing surface and forms a guide space between the guide portion and the force-bearing surface, and the two ends of the guide space are respectively connected to the first through hole and the second through hole.

[0011] In one embodiment, the guide portion near the force-bearing surface is an arc-shaped surface with the same curvature direction as the force-bearing surface, used to form an arc-shaped guide space.

[0012] In one embodiment, the bottom of at least one side of the cable tray is configured as an arc shape.

[0013] In one embodiment, an arc-shaped chamfer is provided at the junction of the force-bearing surface and the first through hole.

[0014] In one embodiment, an arc-shaped guide surface is formed at the junction of the inner side of the guide portion and the second through hole.

[0015] In one embodiment, positioning blocks are provided on both sides of the fixing base, and waist-shaped positioning holes are provided on the positioning blocks.

[0016] In another aspect, this embodiment also discloses an automobile that includes the wiring harness fixing device as described above. Attached Figure Description

[0025] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0026] Example 1 like Figure 1-3 As shown, the present invention provides a wire harness fixing device, which includes: a fixing base 1 and a binding strap 6, wherein the binding strap 6 can be implemented by a cable tie, a clamp or other strip-shaped fixing component.

[0027] The fixing base 1 is provided with a plurality of baffles 2 at intervals along a first direction, wherein the first direction is horizontal and transverse, that is, the length direction of the fixing base 1 in the figure. The plurality of baffles 2 are divided on the fixing base 1 to form a plurality of wire passage grooves 3. The baffles 2 at intervals form wire passage grooves 3 with each other. The baffles 2 can be integrally formed with the fixing base 1. At least one first through hole 4 is provided in the wire passage groove 3. The baffles 2 are provided with second through holes 5 corresponding to the first through holes 4. The number of second through holes 5 is corresponding to the number of first through holes 4. Two first through holes 4 are provided in the wire passage groove 3 and two second through holes 5 are provided on the baffles 2. Preferably, the second through holes 5 and the first through holes 4 are provided in a corresponding manner along the first direction.

[0028] The binding strap 6 is inserted into the first through hole 4 and the second through hole 5 to bind and fix the wire bundle located in the wire passage 3. The binding strap 6 passes through the first through hole 4 in sequence, passes under the fixing seat and then passes out through the second through hole 5 to bind and fix the wire bundle in the wire passage 3. Alternatively, the binding strap 6 passes through the second through hole 5 and then passes out through the first through hole 4. The binding strap 6 passes through both through holes, so that the binding strap 6 can fix the wire bundle located in the wire passage 3 in the wire passage 3, thereby playing a fixing role.

[0029] The first through hole 4 is a strip-shaped through hole arranged along the first direction. By setting the first through hole 4 as a strip-shaped through hole, the binding strap 6 can pass through any position in the first through hole 4 when it closes and fixes the wire harness, which can adapt to wire harnesses of different sizes or be suitable for multi-strand wire harnesses. In this way, the binding strap 6 passing through the second through hole 5 can firmly tie and fix wire harnesses of different diameters and different numbers.

[0030] like Figure 3 As shown, in order to ensure the service life of the strapping 6, the binding force surface 7 at the bottom of the fixing seat between the first through hole 4 and the second through hole 5 is an arc-shaped force surface 7. This arc-shaped force surface 7 is the bottom surface of the fixing seat and is used to connect the first through hole 4 and the second through hole 5 used in pairs. This force surface 7 can be formed by connecting multiple sections of the surface with arc-shaped chamfers at corners, or it can be an arc-shaped surface as a whole.

[0031] When the strapping 6 needs to be tightened after passing through the first through hole 4 and the second through hole 5, the force-bearing surface 7 and the inner side of the strapping 6 contact each other to form the force-bearing surface 7 of the strapping 6. Reducing the sharp protrusions of this force-bearing surface 7 can prevent the strapping 6 from breaking during long-term vibration.

[0032] Furthermore, to facilitate the insertion of the strapping 6 between the two through holes, a guide part 8 is provided at the bottom of the fixing base. The guide part 8 covers the force-bearing surface 7 and forms a guide space 9 with the force-bearing surface 7. The two ends of the guide space 9 are respectively connected to the first through hole 4 and the second through hole 5.

[0033] In this way, after the fixing seat 1 is installed in the target position, when a better strapping 6 is needed, the strapping 6 can be directly inserted through the first through hole 4 or the second through hole 5. The end of the strapping 6 is guided by the guide space 9 formed by the guide part 8 to pass out through another through hole, without having to remove the entire fixing seat 1 to insert the strapping 6.

[0034] To further facilitate the insertion of the strapping 6, the guide part 8 is an arc-shaped surface with the same curvature as the force-bearing surface 7 on the side closest to the force-bearing surface 7, which is used to form an arc-shaped guide space 9. Since the strapping 6 is inserted into the guide space 9, it comes into more contact with the inner side of the guide part 8. Therefore, the inner side of the guide part 8 is formed into an arc-shaped surface with the same curvature as the force-bearing surface 7, so that the strapping 6 can be inserted smoothly and without obstruction.

[0035] In this embodiment, at least one side of the bottom of the wire guide groove 3 is set to be arc-shaped, so that the surface of the wire harness fixed in the wire guide groove 3 fits more closely to the arc-shaped wire guide groove 3, and the fixation is more secure.

[0036] Furthermore, an arc-shaped chamfer is provided at the junction of the force-bearing surface 7 and the second through hole 5. When the wire harness size is small and the strapping 6 needs to contact the edge of the first through hole 4 near the second through hole 5, setting the wire contact on that side of the first through hole 4 as an arc-shaped chamfer can further reduce the wear of the strapping 6.

[0037] An arc-shaped guide surface 10 is formed at the junction of the inner side of the guide portion 8 and the second through hole 5. The arc-shaped guide surface 10 allows the strapping 6, which is inserted through the second through hole 5, to pass through the inner side of the guide portion 8 and all the way to the first through hole 4. The end of the strapping 6 can be guided directly through the guide surface 10 to pass out of the first through hole 4, avoiding the situation where it gets stuck and needs to be fastened by hand.

[0038] In this embodiment, positioning blocks 11 are provided on both sides of the fixed seat, and waist-shaped positioning holes 12 are provided on the positioning blocks 11. Bolts and other fasteners are passed through the positioning holes 12 to fasten the fixed seat 1, which facilitates fine-tuning and fixing of the entire fixed seat 1.

[0039] Example 2 In this embodiment, a vehicle is also disclosed, which includes a wiring harness fixing device as described in Embodiment 1.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
