Description

Technical Field

[0001] The utility model relates to a wire harness fixing bracket with elastic characteristics, belonging to the technical field of engineering vehicles. Background Art

[0002] On large engineering vehicles, due to the long layout distance and large spacing of wire harnesses at some positions, and the relative translation or flipping of the fixing structures at both ends of the wire harness, etc., a certain length needs to be reserved during the wire harness layout to meet the requirements of its length change. Under normal circumstances, rigid structures such as sheet metal bending and welded brackets are used to lift the wire harness from a suitable position in the middle. In some cases, special cables or bellows with rebound characteristics are also used to protect and support the wire harness.

[0003] When using a rigid structure bracket to lift the wire harness from the middle, if the mechanism rotates at a large angle, the bending radius of the wire harness near the lifting and fixing point in the middle will be too small; when using bellows or the same type of material, although it has good flexibility and resilience to relieve the bending and torsion of the wire harness, the length reserved for the wire harness will sag naturally due to the influence of gravity, and there is a situation of interference and wear with other components.

[0004] The main reasons for the above defects are that the distance between the fixing points at both ends of the wire harness is too long, and the elasticity and toughness of the outer protective material of the wire harness (such as bellows or rubber protective layer structure) are insufficient, and it cannot provide effective support for the wire harness during the translation or flipping of the wire harness following the mechanism to ensure that the wire harness layout path is always within a reasonable range. Using special cables or pipeline package structures with high rebound characteristics has a high cost. Summary of the Invention

[0005] In view of the above technical problems, the utility model provides a wire harness fixing bracket with elastic characteristics, which has a simple structure and low cost. It can lift and fix the reserved length position in the middle of the wire harness in the scenario where there is relative translation or flipping at the fixed positions at both ends of the wire harness. The elastic structure inside it bends and twists along with the extension and dragging direction of the wire harness during large-angle flipping or translation of the mechanism, so as to relieve the situation of too small bending radius and too large twisting angle at the wire harness fixing point position, improve the service life of the wire harness, and gradually rebound to the initial state of the bracket when the wire harness fixing mechanism at both ends returns to the initial position, reducing the uncertainty of the layout path of the reserved section of the wire harness and realizing the path guidance of the wire harness.

[0006] The utility model is realized according to the following technical solutions:

[0007] In a first aspect, the utility model provides a wire harness fixing bracket with elastic characteristics, which is used for fixing and supporting a wire harness with relative translation or flipping positions on an engineering vehicle, and includes:

[0008] The fixed end of the bracket is used to install fasteners to assemble the wire harness fixing bracket on a mechanism with relative translation or flipping.

[0009] The movable end of the bracket is equipped with a wire harness fixing component for fixing the reserved length section of the wire harness.

[0010] The main body structure with elastic characteristics undergoes elastic deformation when the mechanism translates or flips at a large angle. It bends and twists along the direction of wire harness extension and drag. When the mechanism gradually returns to the initial position, the reserved length section of the wire harness rebounds to the initial state with the main body structure, realizing the guidance and restriction of the spatial arrangement path of the wire harness.

[0011] In some embodiments, the wire harness fixing bracket is made by bending spring steel wire.

[0012] In some embodiments, both the fixed end of the bracket and the movable end of the bracket are formed by bending spring steel wire into a planar structure or by bending spring steel wire into a planar structure and then welding and installing a plate structure. The fixed end of the bracket is installed on the fixed end of the mechanism through fasteners.

[0013] In some embodiments, the fastener is a bolt, and there is a threaded hole on the fixed end of the mechanism. The planar structure of the fixed end of the bracket is a U-shaped structure or an O-shaped structure. The bolt passes through the U-shaped structure or the O-shaped structure and is then tightened in the threaded hole. The wire harness fixing component is a cable tie or a clamp. The planar structure of the movable end of the bracket is an O-shaped structure. The cable tie directly fixes the wire harness on the O-shaped structure, or the clamp fixes the wire harness and is then fixed on the O-shaped structure through bolts and nuts.

[0014] In some embodiments, the fastener is a bolt, and there is a threaded hole on the fixed end of the mechanism. The installation plate structure of the fixed end of the bracket is a flat plate with at least one through hole. The bolt passes through the installation hole and is then tightened in the threaded hole. The wire harness fixing component is a cable tie or a clamp. The installation plate structure of the movable end of the bracket is a wire arranging plate with multiple installation holes. Each installation hole directly fixes a wire harness through a cable tie, or each through hole fixes a clamp for fixing the wire harness through a bolt, realizing the guidance of multiple groups of wire harnesses.

[0015] In some embodiments, the main body structure is formed by bending spring steel wire into at least one spiral structure.

[0016] In some embodiments, when there are multiple spiral structures, the spring steel wire between adjacent two spiral structures is an arc structure, a straight-line structure, or an arc and straight-line structure.

[0017] In some embodiments, a clamp for fixing the wire harness is provided near the flipping or translation position of the fixed end of the mechanism.

[0018] In some embodiments, a clamp for fixing the wire harness is provided near the flipping or translation position of the movable end of the mechanism; the wire harness between the clamp near the flipping or translation position of the fixed end of the mechanism and the clamp near the flipping or translation position of the movable end of the mechanism is the reserved length section of the wire harness, the wire harness between the clamp near the flipping or translation position of the movable end of the mechanism and the movable end of the bracket is the first reserved length section of the wire harness, and the wire harness between the movable end of the bracket and the clamp near the flipping or translation position of the fixed end of the mechanism is the second reserved length section of the wire harness.

[0019] In a second aspect, the present invention provides an engineering vehicle, including a fixed end of the mechanism and a movable end of the mechanism, and the above-mentioned wire harness fixing bracket with elastic characteristics is installed near the movable end of the fixed end of the mechanism.

[0020] Advantages of the present invention:

[0021] The wire harness fixing bracket with elastic characteristics provided by the present invention can, in the scenario where there is relative translation or flipping between the mechanisms fixed at both ends of the wire harness, support the reserved length section in the middle of the wire harness by using this bracket to prevent the wire harness from interfering and wearing with other components when sagging under the action of gravity. The elastic structure inside the bracket will also bend and twist along with the extension and dragging direction of the wire harness during large-angle flipping or translation of the mechanism, alleviating the situation of too small bending radius and too large twisting angle at the wire harness fixing point position, improving the service life of the wire harness, and during this process, limiting the movement range of the reserved length section in the middle of the wire harness within the elastic deformation range of the movable end of the bracket, reducing the uncertainty of the arrangement path of the reserved section of the wire harness, and realizing path guidance for the wire harness. When a wire arranging plate structure is welded at the position of the movable end of the wire harness fixed on the bracket, multiple groups of wire harnesses can be fixed and constrained simultaneously, reducing wire harness crossing. At the same time, this wire harness fixing bracket is manufactured by bending spring steel wire, with a simple structure, low cost, good elasticity, high toughness, and excellent fatigue resistance, and is suitable for fixing and supporting wire harnesses at positions with relative translation or flipping structures on engineering vehicles.

[0032] It should be noted that these drawings and text descriptions are not intended to limit the scope of the concept of the present utility model in any way, but to illustrate the concept of the present utility model to those skilled in the art by referring to specific embodiments. Detailed implementation manners

[0033] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. The following embodiments are used to illustrate the present utility model but are not used to limit the scope of the present utility model.

[0034] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present utility model.

[0035] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0036] As Figure 1 , Figure 2 , Figure 4 , Figure 6 shown, a wire harness fixing bracket with elastic characteristics is used for fixing and supporting the wire harness with relative translation or flipping positions on an engineering vehicle, and includes a bracket fixed end I, a bracket movable end III, and a main body structure II with elastic characteristics; the bracket fixed end I is used to install fasteners to assemble the wire harness fixing bracket 7 on the mechanism with relative translation or flipping; the bracket movable end III is installed with a wire harness fixing component for fixing the reserved length section of the wire harness; when the mechanism translates or flips at a large angle, the main body structure II with elastic characteristics is elastically deformed under force and bends and twists along the extension and drag direction of the wire harness; when the mechanism starts to gradually return to the initial position, the reserved length section 6 of the wire harness rebounds to the initial state with the main body structure II, realizing the path guiding and restricting of the spatial arrangement path of the wire harness.

[0037] With its good resilience characteristics, anti-bending and anti-twisting characteristics, the present utility model can support the reserved length section of the wire harness and guide the path of the wire harness in the scenario where there is relative translation or flipping at the fixed positions at both ends of the wire harness, reducing both the situation where the bending radius of the fixed points at both ends of the wire harness is too small during the large-angle rotation of the mechanism following the wire harness and the situation where the long reserved wire harness section between the relatively translating mechanisms sags and causes wire harness wear, improving the service life of the wire harness.

[0038] A further solution, as Figure 1 , Figure 2 shown, the wire harness fixing bracket 7 is made by bending spring steel wire.

[0039] A further solution, as Figure 1 , Figure 2 , Figure 3 shown, both the bracket fixed end I and the bracket movable end III are structures formed by bending spring steel wire into a planar structure or structures formed by bending spring steel wire into a planar structure and then welding and installing plates; the bracket fixed end I is installed on the mechanism fixed end 1 through fasteners.

[0040] A preferred solution, as Figure 1 , Figure 2 , Figure 4 , Figure 6As shown, the fastener is a bolt. A threaded hole is provided on the fixed end 1 of the mechanism. The planar structure of the fixed end I of the bracket is a U-shaped structure or an O-shaped structure. The bolt passes through the U-shaped structure or the O-shaped structure and is then tightened in the threaded hole. The wire harness fixing component is a cable tie or a clamp 5. The planar structure of the movable end III of the bracket is an O-shaped structure. The cable tie directly fixes the wire harness on the O-shaped structure, or the clamp 5 fixes the wire harness and is then fixed on the O-shaped structure through bolts and nuts.

[0041] Another preferred solution is as Figure 3 shown. The fastener is a bolt. A threaded hole is provided on the fixed end 1 of the mechanism. The mounting plate structure of the fixed end I of the bracket is a flat plate provided with at least one through hole. The bolt passes through the mounting hole and is then tightened in the threaded hole. The wire harness fixing component is a cable tie or a clamp. The mounting plate structure of the movable end III of the bracket is a wire arranging plate provided with a plurality of mounting holes. Each mounting hole directly fixes a wire harness through a cable tie, or each through hole fixes a clamp 5 for fixing the wire harness through a bolt, so as to guide multiple groups of wire harnesses and reduce wire harness crossing.

[0042] It should be noted that the fastener is not limited to a bolt, the planar structure is not limited to a U-shaped structure or an O-shaped structure, and the wire harness fixing component is not limited to a cable tie or a clamp. In actual use, corresponding adjustments can be made according to requirements.

[0043] A further solution is as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 shown. The main structure II is formed by bending a spring wire into at least one spiral structure.

[0044] A preferred solution is as Figure 2 、 Figure 4 shown. When there are multiple spiral structures, the spring wire between two adjacent spiral structures is an arc structure, a straight-line structure, or an arc and straight-line structure, having good toughness, elasticity, and fatigue resistance.

[0045] It should be noted that the main structure is not limited to the above structure, and any elastic structure that can achieve the following functions is acceptable. The functions are: when the mechanism makes a large-angle flip or translation, the main structure bends and twists along with the extension and drag direction of the wire harness to relieve the situation of too small bending radius and too large torsion angle at the wire harness fixing point position, improve the service life of the wire harness, and when the fixing mechanisms at both ends of the wire harness return to the initial position, gradually rebound to the initial state of the bracket, reduce the uncertainty of the arrangement path of the wire harness reserved section, and achieve path guidance for the wire harness.

[0046] A further solution is as Figure 6As shown in the figure, a clamp 5 for fixing the wire harness is provided on the mechanism at the fixed end I of the bracket. The clamp 5 and the fixed end I of the bracket share the same fastener to be fixed on the mechanism. A rigid wire harness fixing bracket 4 is installed at the movable end 2 (rotating end or movable end) of the mechanism. A clamp 5 for fixing the wire harness is provided on the rigid wire harness fixing bracket 4; the wire harness between the rigid wire harness fixing bracket 4 and the fixed end I of the bracket is the wire harness reserved length section 6, the wire harness between the rigid wire harness fixing bracket 4 and the movable end III of the bracket is the first wire harness reserved length section 6-1, and the wire harness between the movable end III of the bracket and the fixed end I of the bracket is the second wire harness reserved length section 6-2.

[0047] In a further solution, the outer protection of the wire harness uses bellows or braided materials, which have certain tensile and bending resistance capabilities. When the wire harness fixing bracket 7 is in use, one end is fixed on the mechanism, and the other end is installed with a clamp 5 (or other wire harness fixing structures) to fix and support the wire harness reserved length section 6, and the clamp 5 is fixed on the outer protection of the wire harness.

[0048] Taking the working device of a large excavator as an example, the boom rotates around the pin shaft installed at the root of the boom. The boom wire harness connecting the components on the boom is connected from the turntable to the boom. The ideal design solution is to make the wire harness fixing points as close as possible to the hinge part of the rotating pair, and the wire harness path between the two fixed points is close to the rotation axis to reduce the reserved length required for the moving section of the wire harness and prevent the reserved wire harness from falling onto the turntable and wearing. However, due to the installation of components such as hydraulic pipelines near the position of the rotation axis, during the rotation of the boom, the wire harness should avoid the corresponding components, resulting in a large difference in the path length change, and a longer wire harness needs to be reserved to meet the length change requirements. The actual fixing type of the wire harness refers to Figure 5 . Figure 5 In the embodiment, there is relative rotation between the fixed end 1 of the mechanism and the movable end 2 of the mechanism. The wire harness uses a rigid wire harness fixing bracket 4 and a clamp 5 to fix the wire harness on both sides of the mechanism. After fixing, a wire harness fixing section 3 and a wire harness reserved length section 6 are formed. During the rotation of the wire harness following the movable end 2 of the mechanism, when the two fixed clamps are close, it will cause an increase in the length of the wire harness reserved length section 6. When the elasticity and toughness of the wire harness at this position cannot provide effective support for the wire harness, the wire harness section will droop and wear against the fixed end 1 of the mechanism.

[0049] When an elastic characteristic bracket is used for fixing the wire harness between the rotating mechanisms, reference can be made to the embodiments such as Figure 6 . Based on Figure 5Structure, add a wire harness fixing bracket 7 with elastic characteristics to the fixed end 1 of the structure. The other end of the wire harness fixing bracket 7 is installed with a clamp 5 to fix the reserved length section 6 of the wire harness and form a lifting support for this section of the wire harness, reducing the degree of drooping of the wire harness section. At the same time, based on the above structure, a first wire harness reserved length section 6-1 and a second wire harness reserved length section 6-2 will be formed. During the rotation of the movable end 2 of the wire harness following mechanism, when the two clamps 5 gradually move away from each other, the first wire harness reserved length section 6-1 is stretched and extended. In this state, the outer protection of the wire harness (such as corrugated pipe or braided material, etc.) is stressed and gradually drags the clamp 5 at the movable end III of the bracket. The main structure II of the wire harness fixing bracket 7 is elastically deformed, and the second wire harness reserved length section (6-2) begins to be stretched and extended as the movable end III of the bracket moves until the wire harness fixing points at both ends of the relative rotation mechanism reach the maximum distance or stop rotating. When the fixed end 1 of the mechanism and the movable end 2 of the mechanism gradually return to the initial position, the reserved length section 6 of the wire harness rebounds to the initial state with the elastic wire harness bracket, realizing the path guidance and restriction of the spatial arrangement of the wire harness.

[0050] The utility model also provides an engineering vehicle, including a fixed end of the mechanism and a movable end of the mechanism. The above-mentioned wire harness fixing bracket with elastic characteristics is installed near the movable end of the mechanism at the fixed end of the mechanism.

[0051] In summary, the wire harness fixing bracket with elastic characteristics provided by the utility model can, in the scenario where there is relative translation or flipping between the mechanisms fixed at both ends of the wire harness, support the reserved length section in the middle of the wire harness by using this bracket to prevent the wire harness from interfering and wearing with other components when drooping under the action of gravity. The elastic structure inside the bracket will also bend and twist along with the extension and dragging direction of the wire harness during large-angle flipping or translation of the mechanism, alleviating the situation of too small bending radius and too large twisting angle at the wire harness fixing point position, improving the service life of the wire harness. And in this process, the movement range of the reserved length section in the middle of the wire harness is limited within the elastic deformation range of the movable end of the bracket, reducing the uncertainty of the arrangement path of the reserved section of the wire harness and realizing the path guidance of the wire harness. When a wire arranging board structure is welded at the position of the movable end of the wire harness fixed on the bracket, multiple groups of wire harnesses can be fixed and constrained simultaneously, reducing wire harness crossing. At the same time, this bracket is manufactured by bending spring steel wire, with simple structure, low cost, good elasticity, high toughness and excellent fatigue resistance, and is suitable for fixing and supporting wire harnesses at positions with relative translation or flipping structures on engineering vehicles.
