Abstract
Description

[0002] New energy vehicles are equipped with numerous wiring harnesses, such as high-voltage harnesses that provide high-voltage electricity to the vehicle. These harnesses have high safety requirements, and typically, sealing rubber sleeves are installed at the sheet metal holes through which the harnesses pass. These sleeves are used for waterproofing and dustproofing, and to prevent direct friction between the harnesses and the sheet metal parts. In some related technologies, the rubber sleeves are fixed to the sheet metal parts by screws. In scenarios where inverted bolts are used, one hand needs to hold the rubber assembly while the other hand reaches behind the hole to tighten the nut, which is time-consuming and laborious, affecting assembly efficiency.

Detailed Implementation
[0026] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.
[0027] like Figures 1 to 6 As shown, this exemplary embodiment provides a wire harness through-hole sheath assembly. It is suitable for installation at through-holes in vehicle body structural components, such as through-holes in wheel arch sheet metal for high-voltage wire harnesses to pass through. Specifically, the wire harness through-hole sheath assembly includes a rubber component 1 and a rigid bracket disposed on the rubber component 1. The rubber component 1 has a wire harness hole 111 for the wire harness to pass through. The rubber component 1 seals the through-hole to prevent dust and water ingress. The rigid bracket 2 can be made of plastic or metal and is used to support the rubber component 1 and install the wire harness through-hole sheath assembly onto the vehicle body structural component. The rigid bracket 2 includes threaded fasteners 21 for screwing into the vehicle body structural component; the threaded fasteners 21 can be, for example, studs pre-installed on the rigid bracket 2.
[0028] In some related technologies, the rigid bracket 2 is fixed to the vehicle body structure by snap-fit. However, in wire harness through-hole sheath assemblies with large wire diameters, such as those used in high-voltage wire harnesses, snap-fit fixation cannot guarantee airtightness and is also prone to torsion under the action of wire harness deflection force. Therefore, in areas with high protection requirements, screw-fit fixation is more commonly used.
[0029] The wiring harness through-hole sheath assembly disclosed herein is a wiring harness through-hole sheath assembly based on screw fixing. In the scenario of inverted bolt fixing, the wiring harness through-hole sheath assembly needs to be installed from the back of the sheet metal part. The threaded fasteners 21, such as studs, pass through the sheet metal part from bottom to top, and then the nut is tightened. During the tightening of the nut, one hand needs to hold the wiring harness through-hole sheath assembly, and the other hand needs to reach to the back of the hole to tighten the nut. Considering this technical problem, the wiring harness through-hole sheath assembly disclosed herein includes a pre-hanging structure 22 in its rigid bracket 2. The pre-hanging structure 22 is used to pre-hang the wiring harness through-hole sheath assembly to the vehicle body structural component, for example, it can be hung at the through-hole. That is, the pre-hanging structure 22 plays the role of pre-fixing the wiring harness through-hole sheath assembly to the vehicle body structural component. Here, "pre-" refers to before tightening the threaded fasteners 21. Tightening the threaded fasteners 21 is used to ensure the connection strength of the sheath assembly and the sealing performance of the rubber part 1 and the vehicle body structural component.
[0030] The wiring harness through-hole sheath assembly provided in this disclosure adds a pre-hanging structure 22 to the relevant technical solutions. This allows the operator to pre-fix the wiring harness through-hole rubber parts to the vehicle body structure before tightening the threaded fasteners 21. In this way, the operator no longer needs to hold the inverted sheath assembly with one hand and tighten the threaded fasteners with the other hand. This helps to reduce the difficulty of assembling the wiring harness through-hole sheath assembly, improve the flexibility of assembly, and thus improve the efficiency of assembly.
[0031] In some implementations, such as Figure 2 and Figure 3 As shown, the pre-attached structure 22 includes a deformable portion 221 and a clamping portion 222. The deformable portion 221 has a first state of being compressed inward when passing through the through hole and a second state of releasing elasticity after passing through the through hole. The clamping portion 222 is engaged with the through hole when the deformable portion 221 is in the second state. The pre-attached structure 22 can be constructed as an elastic snap, wherein the deformable portion 221 can be compressed inward to pass through the through hole and then release elasticity under the action of elastic restoring force, and the clamping portion 222 can be constructed as a hook to reliably engage with the through hole, preventing the wire harness through hole sheath assembly from accidentally coming out of the through hole during the tightening of the nut.
[0032] In other embodiments, the pre-attached structure 22 further includes a guide portion 223, which has a guide slope that tapers along the direction of insertion into the through hole. During the installation of the wire harness through hole sheath assembly, under the action of the guide portion 223, the pre-attached structure 22 contacts the hole wall during insertion into the through hole, and drives the deformation portion 221 to compress inward, thus eliminating the need for the operator to manually compress the deformation portion 221 inward, making the operation more convenient.
[0033] To improve the reliability of the pre-fixing between the pre-attached structure 22 and the vehicle body structural components, in some embodiments, the rigid bracket 2 includes an annular boss 24 for the passage of wire harnesses. The internal opening of the annular boss 24 corresponds to the wire harness hole 111 to facilitate the passage of the wire harness. Multiple pre-attached structures 22 can be provided, symmetrically arranged on the annular boss 24. For example, in... Figure 4 The diagram shows two pre-attached structures 22 arranged symmetrically at 180° intervals. In other embodiments, for example, four pre-attached structures 22 may be provided, arranged symmetrically at 90° intervals. The pre-attached structures 22 can be integrally formed with pre-annular bosses 24, for example, by injection molding. This integral construction of the pre-attached structure 22 and the rigid support 2 is beneficial to improving the structural strength of the pre-attached structure 22.
[0034] Different mating installation relationships can be used between the rubber component 1 and the rigid bracket 2. In some embodiments, such as... Figure 1 As shown, the rubber component 1 is disposed on the outer periphery of the rigid support 2. In other embodiments, the rigid support 2 may be disposed on the outer periphery of the rubber component 1. Taking the rubber component 1 disposed on the outer periphery of the rigid support 2 as an example, reference can also be made to... Figures 4 to 6 The rubber component 1 is constructed as a groove formed by the bottom wall 11 and the side wall 12, and the rigid support 2 is housed inside the rubber component 1.
[0035] Among them, such as Figure 3 As shown, the end of the side panel 12 away from the bottom wall 11 is bent inward toward the rubber component 1 to form a folded edge 13. The bottom wall 11 and the folded edge 13 clamp the rigid bracket 2 from both sides. Specifically, the rubber component 1 and the rigid bracket 2 are fitted with an interference fit. During installation, the rigid bracket 2 can be squeezed into the space formed between the bottom wall 11 and the folded edge 13. Under the action of elastic force, the rigid bracket 2 can be reliably housed in the rubber component 1, preventing the rubber component 1 and the rigid bracket 2 from separating during the installation of the wire harness through-hole sheath assembly and the insertion of the wire harness.
[0036] Continue to refer to Figure 3 The folded edge 13 is provided with a first stop 131 protruding towards the bottom wall 11, and the rigid bracket 2 is provided with a second stop 231. The first stop 131 and the second stop 231 cooperate to restrict the lateral movement of the rigid bracket 2. This helps to further improve the reliability of the connection between the rubber part 1 and the rigid bracket 2, and avoids the separation of the rubber part 1 and the rigid bracket 2 during the installation of the wire harness through-hole sheath assembly and the insertion of the wire harness.
[0037] In addition, such as Figure 2As shown, a sealing lip 14 is provided at the end of the side panel 12 away from the bottom wall 11. The sealing lip 14 is used to seal against the vehicle body structural component. When installing the wiring harness through-hole sleeve assembly, as the lock nut is tightened, the rigid bracket 2 causes the rubber component 1 to gradually press against the vehicle body structural component, thereby achieving a sealing effect. By providing the sealing lip 14, the contact area between the rubber component 1 and the vehicle body structural component can be increased, thereby improving the sealing effect.
[0038] In some implementations, taking a stud as an example, the threaded fastener 21 is used as an example, such as Figure 5 As shown, the rigid bracket 2 is provided with mounting holes 232 for mounting studs. A reinforcing structure 25 is provided at the position corresponding to the mounting holes 232, which helps improve the reliability of the connection between the threaded fastener 21 and the rigid bracket 2, thereby improving the reliability of the connection between the wire harness through-hole sheath assembly and the vehicle body structural components. The reinforcing structure 25 can be constructed, for example, including annular reinforcing ribs 251 and a plurality of strip-shaped reinforcing ribs 252 circumferentially spaced around the annular reinforcing ribs 251, with the strip-shaped reinforcing ribs 252 extending radially.
[0039] like Figure 1 He Ru Figure 4 As shown, the wiring harness hole 111 extends obliquely at the bottom of the rubber component 1. For example, the wiring harness hole 111 extends to form a tubular rubber sleeve 112, which is used to protect the wiring harness from direct frictional contact with the vehicle body structural components.
[0040] According to a second aspect of the present disclosure, a vehicle is also provided that includes the wiring harness through-hole sheath assembly of any of the above-mentioned embodiments and has all of its beneficial effects, which will not be repeated here.
[0041] In the above detailed description, reference has been made to the accompanying drawings, which illustrate specific aspects of this disclosure by way of illustration. In this regard, terms indicating direction or positional relationship, such as “center,” “longitudinal,” “lateral,” “length,” “width,” “thickness,” “upper,” “lower,” “front,” “rear,” “left,” “right,” “vertical,” “horizontal,” “top,” “bottom,” “inner,” “outer,” “clockwise,” “counterclockwise,” “axial,” “radial,” and “circumferential,” are used with reference to the orientation of the described figures. Since components of the described device can be positioned in multiple different orientations, directional terms are used for illustrative purposes and not for limitation. It should be understood that other aspects can be utilized and structural or logical changes can be made without departing from the concept of this disclosure. Therefore, the following detailed description should not be considered limiting.
[0042] It should be understood that, unless otherwise specifically indicated, features of various embodiments of this disclosure described herein can be combined with each other. As used herein, the term “and / or” includes any one of the relevant listed items and any combination of any two or more; similarly, “at least one of…” includes any one of the relevant listed items and any combination of any two or more.
[0043] It should be understood that, unless otherwise expressly specified and limited, the terms "joining," "attaching," "installing," "connecting," "linking," "fixing," etc., used in the embodiments of this disclosure 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, an electrical connection, or a connection that allows communication between them; 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, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms herein based on the specific circumstances.
[0044] Furthermore, the term "above" as used herein with respect to components, elements, or material layers formed or located "above" a surface may be used to indicate that the component, element, or material layer is "indirectly" positioned (e.g., placed, formed, deposited, etc.) on the surface such that one or more additional components, elements, or layers are arranged between the surface and the component, element, or material layer. However, the term "above" as used with respect to components, elements, or material layers formed or located "above" a surface may also optionally have a specific meaning: that the component, element, or material layer is "directly" positioned (e.g., placed, formed, deposited, etc.) on the surface, for example, in direct contact with the surface.
[0045] Although terms such as “first,” “second,” and “third” may be used herein to describe various components, parts, regions, layers, or sections, these components, parts, regions, layers, or sections are not limited to these terms. Rather, these terms are used only to distinguish one component, part, region, layer, or section from another. Therefore, without departing from the teachings of the examples described herein, the first component, part, region, layer, or section mentioned in the examples may also be referred to as the second component, part, region, layer, or section. Furthermore, the terms “first” and “second” are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as “first” or “second” may explicitly or implicitly include at least one of that feature. In the description herein, “a plurality” means at least two, such as two, three, etc., unless otherwise explicitly specified.
[0046] It should be understood that spatial relative terms, such as “above,” “upper,” “below,” and “lower,” are used herein to describe the relationship between one element and another shown in the figures. In addition to the orientation depicted in the figures, these spatial relative terms are also intended to encompass different orientations of the device in use or operation. For example, if the device in the figures is flipped, an element described as “above” or “upper” relative to another element would be “below” or “lower” relative to that other element. Thus, depending on the spatial orientation of the device, the term “above” encompasses both above and below orientations. Devices may have other orientations (e.g., rotated 90 degrees or in other orientations), and the spatial relative terms used herein should be interpreted accordingly.
[0047] Furthermore, the term “exemplary” is used herein to mean serving as an example, instance, or illustration. Any aspect or design described herein as “exemplary” is not necessarily to be construed as advantageous compared to other aspects or designs. Rather, the use of the term “exemplary” is intended to present the concept in a concrete manner. As used herein, the term “or” is intended to mean an inclusive “or” rather than an exclusive “or.” That is, unless otherwise specified or clear from the context, “X applies A or B” is intended to mean any of the natural inclusive arrangements. That is, “X applies A or B” satisfies any of the foregoing instances if X applies A; X applies B; or both X applies A and B. Additionally, unless otherwise specified or clear from the context to refer to the singular form, the articles “a” and “an” as used in this application and the appended claims are generally understood to mean “one or more.”
[0048] Similarly, although this disclosure has been shown and described with respect to one or more implementations, equivalent variations and modifications will occur to those skilled in the art upon reading and understanding this specification and the accompanying drawings. This disclosure includes all such modifications and variations and is limited only by the scope of the claims. In particular, with respect to the various functions performed by the components described above (e.g., elements, resources, etc.), unless otherwise indicated, the terminology used to describe such components is intended to correspond to any component (functionally equivalent) that performs the specific function of the described component, even if structurally not equivalent to the disclosed structure. Furthermore, although specific features of this disclosure may have been disclosed with respect to only one of several implementations, such features may be combined with one or more other features of other implementations, as may be desired and advantageous to any given or particular application. Moreover, with regard to the terms “comprising,” “owning,” “having,” “having,” or variations thereof as used in the detailed description or claims, such terms are intended to be inclusive in a manner similar to the term “including.”
[0049] Other embodiments of this disclosure will readily occur to those skilled in the art upon consideration of the specification and practice of the invention disclosed herein. This application is intended to cover any variations, uses, or adaptations of this disclosure that follow the general principles of this disclosure and include common knowledge or customary techniques in the art not disclosed herein. The specification and examples are to be considered exemplary only, and the true scope and spirit of this disclosure are indicated by the appended claims.
