Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts, in particular to a wire harness sheath and an automobile. Background Art

[0002] In modern automobile manufacturing, the wire harness, as an important part of the vehicle, is responsible for connecting various electrical devices to ensure the normal operation of the vehicle. The installation and fixation of the wire harness usually require the use of wire harness rubber sleeves to protect the wire harness, prevent wear and corrosion, and play a role in guiding and fixing. The existing wire harness rubber sleeves are mainly made of rubber or plastic materials, and channels are provided inside for accommodating and fixing the wire harness. In addition, the wire harness rubber sleeve also needs to have good sealing performance to prevent impurities such as moisture and dust from entering and affecting the normal operation of the wire harness.

[0003] However, with the increase in vehicle electrical appliances and the improvement of the requirements for the human-machine space, the layout space of the whole vehicle wire harness is extremely tense and limited. Especially in some narrow spaces, the assembly of the wire harness is difficult or even impossible, which increases the assembly time of the whole vehicle and reduces the assembly efficiency of the whole vehicle. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a wire harness sheath that is convenient to install and can improve the assembly efficiency.

[0005] To achieve the above purpose, the utility model provides a wire harness sheath, which includes a main body and a handheld part. The two ends of the main body are provided with a communicating wire inlet and a wire outlet for the wire harness to pass through. The main body is recessed from its outer surface along a first direction to form an installation groove for clamping with the wire passing hole of the vehicle body cross beam. The width of the installation groove is smaller than the thickness of the main body, so that the main body correspondingly forms a first connection part and a second connection part on the opposite sides of the installation groove. The first connection part is used to pass through the wire passing hole and connect with the vehicle body cross beam, and the handheld part is connected with the first connection part.

[0006] Optionally, the handheld part is strip-shaped, and the first connection part protrudes from its surface along a direction away from the second connection part to form the handheld part. An anti-slip part is connected to one end of the handheld part away from the first connection part.

[0007] Optionally, the wire harness sheath of the utility model further includes a guiding part for guiding the running direction of the part of the wire harness passing through the main body. The guiding part is connected with the second connection part. The guiding part is a hollow column, and the axial direction of the guiding part is parallel to the first direction or inclined relative to the first direction.

[0008] Optionally, a limiting ring is formed by radially protruding from the inner surface of the guiding portion. The limiting ring is used to abut against the wire harness to fix a part of the wire harness to the guiding portion. A flange is formed by radially protruding from the outer surface of the end of the guiding portion away from the main body. The flange is used to increase the thickness of the end of the guiding portion. A reinforcing rib is connected between the middle of the guiding portion and the main body.

[0009] Optionally, a sealing ring is formed by protruding from the surface of the second connecting portion close to the first connecting portion.

[0010] The present utility model provides an automobile, including a body cross beam, a wire harness, and the wire harness sheath. The wire harness is fixed to the body cross beam through the wire harness sheath.

[0027] Please refer to Figure 1 , the present utility model provides an automobile, including a body crossbeam 4, a wiring harness 5 and a wiring harness sheath. A wiring harness through-hole for the wiring harness 5 to pass through is provided on the body crossbeam 4. Specifically, the body crossbeam 4 includes an outer crossbeam panel 42 and an inner crossbeam panel 41 arranged oppositely. The above-mentioned wiring harness through-hole is provided on the outer crossbeam panel 42, and an opening for installing or avoiding other components is preset on the inner crossbeam panel 41. During installation, the wiring harness sheath passes through the wiring harness through-hole and is fixedly connected to the body crossbeam 4. A part of the wiring harness 5 passes through the wiring harness sheath and is connected to the wiring harness sheath. The wiring harness 5 passes through the wiring harness through-hole and the opening in sequence, and a part of the wiring harness 5 is fixed to the body crossbeam 4 through the wiring harness sheath. It can be understood that the wiring harness sheath of the present utility model can also be installed on other components such as door sheet metal and floor sheet metal that need to install the wiring harness 5.

[0028] Please refer to Figure 2 and Figure 3, the wire harness sheath of the present utility model includes a main body 1, a handheld part 2 and a guiding part 3. Optionally, the main body 1, the handheld part 2 and the guiding part 3 are integrally formed. Among them, the guiding part 3 is used to guide the wire harness 5 through the part of the main body 1. The guiding part 3 and the handheld part 2 can be connected to opposite sides of the main body 1, or the guiding part 3 and the handheld part 2 can also be connected to the same side of the main body 1. Since the opening reserved in the crossbeam inner plate 41 is small, it is difficult to install the wire harness sheath through the above opening. When the layout space of the wire harness 5 is limited, the operator can conveniently fix the main body 1 to the crossbeam inner plate 41 through the opening by the handheld part 2, thus facilitating installation and improving assembly efficiency. In addition, pulling the wire harness 5 during installation can be avoided through the handheld part 2, thereby preventing damage to the wire harness 5.

[0029] In one example, an installation groove 11 is formed by the main body 1 recessing along a first direction from its outer surface. The installation groove 11 is used to be clamped with a part of the crossbeam outer plate 42 around the wire harness through-hole, so that the wire harness sheath is clamped to the crossbeam outer plate 42 through the installation groove 11. Specifically, the width of the installation groove 11 is smaller than the thickness of the main body 1, so that a first connecting part 12 and a second connecting part 13 are correspondingly formed on opposite sides of the main body 1 at the installation groove 11. The first connecting part 12 is used to pass through the wire harness through-hole and connect with the vehicle body crossbeam 4. At this time, the second connecting part 13 abuts against the outer surface of the crossbeam outer plate 42. Optionally, the first connecting part 12 and the second connecting part 13 can also be fixedly connected to the crossbeam outer plate 42 through fasteners such as bolts and nuts. In this embodiment, the second direction is the thickness direction of the first connecting part 12, and the first direction is perpendicular to the second direction.

[0030] Please refer to Figure 3 and Figure 4 , an inlet 121 is opened at one end of the main body 1, and an outlet 131 is opened at the other end of the main body 1. The inlet 121 is communicated with the outlet 131 for the wire harness 5 to pass through. Specifically, the inlet 121 and the outlet 131 are respectively opened at opposite ends of the main body 1 along the second direction. Optionally, the axial direction of the inlet 121 is parallel to the thickness direction of the main body 1, and the diameter of the inlet 121 is not less than the diameter of the outlet 131, so that the wire harness 5 can more easily penetrate into the main body 1 from the inlet 121, thus facilitating installation.

[0031] Optionally, the guiding part 3 is connected to the second connecting part 13, and the handheld part 2 is connected to the first connecting part 12. The operator tightens the main body 1 from above the wire harness through-hole to the installation groove 11 to be clamped with the vehicle body crossbeam 4 through the opening reserved in the crossbeam inner plate 41, so that the crossbeam outer plate 42 is closely attached to the installation groove 11, thereby preventing impurities such as moisture or dust from entering to ensure the sealing performance.

[0032] Optionally, the projection of the main body 1 in the second direction is oblong or circular. In one example, the projections of the first connecting portion 12 and the second connecting portion 13 in the second direction are both oblong. The wire harness through-hole of the crossbeam inner plate 41 is an oblong hole that matches the first connecting portion 12, so as to define the angle between the wire harness sheath and the crossbeam inner plate 41, thereby improving the installation accuracy. Optionally, the projection of the first connecting portion 12 in the first direction is trapezoidal or arc-shaped, that is, the side surface of the first connecting portion 12 is inclined relative to the second direction. Specifically, the cross-sectional area of the first connecting portion 12 gradually decreases in the direction away from the second connecting portion 13, making it easier for the first connecting portion 12 to pass through the wire harness through-hole during installation and improving the installation efficiency.

[0033] Optionally, a sealing ring 132 is formed by protruding from the surface of the second connecting portion 13 close to the first connecting portion 12. The cross-section of the sealing ring 132 in its radial direction is in the shape of an arc, a triangle, a trapezoid, a rectangle, etc., further improving the sealing performance.

[0034] In one example, the guiding portion 3 is a hollow column. According to the wiring requirements of the wire harness 5, the angle between the axial direction of the guiding portion 3 and the second direction can be any angle. Optionally, the axial direction of the guiding portion 3 is parallel to the first direction or inclined relative to the first direction. Preferably, the angle between the axial direction of the guiding portion 3 and the first direction is less than 45°. As Figure 4 shown in the embodiment, the axial direction of the guiding portion 3 is substantially parallel to the first direction. By means of the guiding portion 3, interference between the wire harness 5 and other components around the second connecting portion 13 can be avoided.

[0035] Optionally, a limiting ring 31 is formed by protruding from the inner surface of the guiding portion 3 in the radial direction. The wire harness 5 passes through the guiding portion 3 and abuts against the limiting ring 31, which can relatively fix the wire harness 5 and the wire harness sheath, thereby increasing the connection stability and reducing the bumping abnormal noise generated by the wire harness 5 and the wire harness sheath during vehicle driving. The number of the limiting rings 31 can be one or more. Preferably, two limiting rings 31 are arranged at intervals on the inner surface of the guiding portion 3.

[0036] Optionally, a flange 32 is formed by protruding from the outer surface of the end of the guiding portion 3 away from the main body 1 in the radial direction. By increasing the thickness of the end of the guiding portion 3 through the flange 32, curling, deformation, etc. of the end of the guiding portion 3 can be avoided, and the structural strength of the end of the guiding portion 3 can be improved. In cooperation with the limiting ring 31, the fixing effect on the wire harness 5 can be enhanced, and the sealing performance can be improved.

[0037] Optionally, a reinforcing rib 33 is connected between the middle of the guiding portion 3 and the main body 1, which can improve the connection strength between the guiding portion 3 and the main body 1, thereby avoiding the situation that the wire harness 5 is too hard to bend and the direction of the guiding portion 3 is changed due to the restoring force generated by the bending of the wire harness 5 itself, and further ensuring the routing of the wire harness 5 passing through the guiding portion 3.

[0038] Please refer toFigure 2 and Figure 3 The handheld part 2 is strip-shaped and connected to one side of the first connecting part 12 away from the second connecting part 13. Specifically, the first connecting part 12 protrudes from its surface in a direction away from the second connecting part 13 to form the handheld part 2. The number of the handheld parts 2 can be one or more. In this embodiment, the number of the handheld parts 2 is two, and the two handheld parts 2 are arranged at opposite ends of the first connecting part 12 along the first direction. During installation, the first connecting part 12 is pressed tightly into the wire harness through hole, and by pulling the two handheld parts 2 simultaneously, the applied force can be made more balanced, thus facilitating installation and improving installation accuracy.

[0039] Optionally, the two handheld parts 2 protrude from one end away from the first connecting part 12 in directions away from each other to form anti-slip parts 21, which further facilitates installation.

[0040] The above is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present utility model should be covered within the protection scope of the present utility model.
