[0002] With the development of electrification and intelligent vehicles, new energy vehicles have added multiple functions, resulting in increasingly complex wiring harness circuits for signal transmission. These wiring harnesses are difficult to assemble at corners, and lack specific guidance and restraint after assembly. This can easily cause unusual noises when the vehicle is jolted, and even cause the wiring harness to deviate from its intended position, easily interfering with surrounding components. Long-term relative movement can lead to risks such as wiring harness breakage and short circuits. To address these issues, protective devices are typically added to wiring harnesses. However, existing protective devices have a single output line and are incompatible with wiring harnesses of different configurations, resulting in poor adaptability.

DETAILED DESCRIPTION

[0025] To make the purpose, technical solution, and advantages of the present invention more clear, the technical solution of the present invention will be described clearly and completely below. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments derived by persons of ordinary skill in the art without inventive effort are also within the scope of protection of the present invention.

Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0027] It should also be noted that, in the description of this utility model, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0028] Example 1

[0029] like Figures 1-4 As shown, this embodiment provides a wire harness protection box, comprising an upper wire harness box cover 1, a lower wire harness box cover 2, a first wire harness channel 3 and a second wire harness channel 4 connected to each other, wherein the first wire harness channel 1 and the second wire harness channel 2 are formed by connecting the upper wire harness box cover 1 and the lower wire harness box cover 2;

[0030] The lower cover 2 of the wire protection box is provided with an expansion component 5, which is used to fix the external wiring harness.

[0031] The first and second wiring harness channels are formed by connecting the upper and lower wire protection box covers. Both channels can be used to accommodate wiring harnesses, and the upper and lower wire protection box covers provide protection, preventing the wiring harnesses from colliding with other vehicle components during driving, thereby avoiding noise and wear and tear of components and materials. They are easy to use and have no requirements for wiring harness specifications, models, or quantity. Furthermore, due to the restraining effect of the upper and lower wire protection box covers, the wiring harnesses within the first and second wiring harness channels are more neatly arranged and aesthetically pleasing, with highly consistent routing paths and a less cluttered appearance.

[0032] In this embodiment, the first wiring harness channel and the second wiring harness channel have different directions. Wiring harnesses with different direction requirements can use wiring harness channels with different directions, which has higher adaptability and flexibility.

[0033] If some wiring harnesses cannot be routed through the first and second harness channels due to installation location or other reasons, they can be connected to an expansion assembly, which can also stably secure them to the harness housing to prevent them from shaking. It should be understood that the "external wiring harness" mentioned above refers to the wiring harness connected outside the harness housing, as distinguished from the wiring harnesses that use the first and second harness channels mentioned above.

[0034] Furthermore, the wire harness box lower cover 2 includes a first side wall 201, a second side wall 202, and a bottom surface 203. The first side wall 201 and the second side wall 202 are arranged on both sides of the bottom surface 203. The first side wall 201, the second side wall 202, the bottom surface 203, and the wire harness box upper cover 1 form a first wire harness channel 3. It can be seen that the first wire harness channel in this embodiment is actually formed by the first side wall, the second side wall, the bottom surface, and the wire harness box upper cover.

[0035] The present invention imposes no particular restrictions on the angles between the first and second side walls and the bottom surface, as long as they can achieve the function of forming the first wiring harness channel. Preferably, in this embodiment, the first and second side walls are arranged parallel to each other and perpendicular to the bottom surface. This design provides a neat structure, ease of fabrication, and a more convenient and secure connection between the upper and lower covers of the wiring harness box.

[0036] Furthermore, the expansion assembly 5 is disposed on the bottom surface 203. The expansion assembly 5 includes an expansion assembly body 501 and a connection hole 502 disposed on the expansion assembly body 501. The expansion assembly body 501 is connected to the bottom surface 203, and the connection hole 502 is used to secure the external wiring harness. In this embodiment, the expansion assembly is disposed on the above-mentioned bottom surface to minimize interference between the external wiring harness and other wiring harnesses and the structure of the wiring harness protection box itself, and can provide the external wiring harness with more flexible routing, such as being able to be arranged parallel to the bottom surface, perpendicular to the bottom surface, or arranged at other angles.

[0037] Preferably, the connection hole is provided at the bottom end of the expansion assembly body to facilitate the fixing of the external wiring harness. It should be noted that when fixing the external wiring harness, the external wiring harness is first connected to an external connector, which is provided with a bolt or screw, and then the bolt or screw is screwed into the connection hole to achieve the effect of fixing the external wiring harness to the connection hole. Obviously, the connection block can also be provided on the side of the expansion assembly body to achieve the corresponding function. This embodiment does not adopt this approach, so it will not be described here.

[0038] Furthermore, mounting ears 205 are connected to the second side wall 203. Mounting ears 205 are used to connect to the first vehicle body component, and washers 206 are disposed within the mounting ears 205. In this embodiment, mounting ears are provided on the second side wall to connect to the first vehicle body component, thereby stably connecting the wiring harness protection box to the vehicle interior and further improving structural stability. In actual installation, bolts or screws are typically used, and the placement of washers within the mounting ears further enhances mounting strength.

[0039] Furthermore, the first side wall 201 and the second side wall 202 are each provided with a first clamping member 207, and the upper cover 1 of the wire protection box is provided with a second clamping member 101 that matches the first clamping member 207. The first clamping member 207 and the second clamping member 101 can be used to achieve the clamping connection between the lower cover 2 and the upper cover 1 of the wire protection box. In this embodiment, the lower cover and the upper cover of the wire protection box are clamped together by the first clamping member and the second clamping member. After the wiring harness is installed and fixed in the first wiring harness channel and the second wiring harness channel, the upper cover and the lower cover can be fastened together, which is very convenient and quick.

[0040] Optionally, the number of the first and second clamping members is more than 2, such as 2, 4, 6, 8, etc. Preferably, the number of the first clamping members on the first side wall and the first clamping members on the second side wall are equal and their positions correspond to each other (e.g., symmetrically arranged).

[0041] It should be noted that this embodiment does not limit the structural form of the first clamping member and the second clamping member. As long as the corresponding clamping function can be achieved, any existing achievable structural form can be adopted.

[0042] Furthermore, the lower cover 2 of the wire protection box is provided with at least three groups of wire harness fixing assemblies 208, and the at least three groups of wire harness fixing assemblies 208 are respectively provided at both ends and the middle corner of the lower cover 2 of the wire protection box. After the wire harness is placed in the first wire harness channel, the wire harness needs to be fixed to achieve a better fixing effect and prevent the wire harness from moving in the first wire harness channel. Therefore, this embodiment uses at least three groups of wire harness fixing assemblies to fix the wire harness, which are respectively provided at both ends and the middle corner of the lower cover of the wire protection box. It can also be seen here that the lower cover of the wire protection box has corners and is not straight, which is also in line with actual engineering applications. Generally, when the wire harness needs to change direction, the demand for the wire protection box is greater. The utility model does not specifically limit the angle of the corner, and 90 degrees is preferably used in this embodiment.

[0043] Furthermore, the wire harness securing assembly 208 includes a cable tie 209 and a cable tie mounting hole 2010. The cable tie mounting hole 2010 is provided in the lower cover 2 of the wire harness housing. The cable tie 209 passes through the cable tie mounting hole 2010 to secure the wire harness within the first wire harness passage 3. In this embodiment, cable ties are used to secure the wire harness within the first wire harness passage. Cable ties are readily available and readily replaceable. To adapt a different wire harness, no other components of the wire harness housing need to be adjusted; only the cable tie needs to be replaced.

[0044] Furthermore, the upper cover 1 of the wire harness enclosure is provided with a mounting clip 102 for connecting to the second vehicle body component. The mounting clip is used to connect to the second vehicle body component. Compared to bolt or screw connections, the mounting clip is more efficient, and thus the mounting clip primarily serves a pre-assembly function, that is, the mounting clip is first used to initially secure the wire harness enclosure, and then the mounting ears are used for final securement.

[0045] Preferably, the central axis of the above-mentioned mounting ear, the central axis of the above-mentioned expansion component and the central axis of the above-mentioned mounting buckle are staggered and do not overlap with each other, so as to facilitate the installation of the external wiring harness and the wiring harness protection box, and at the same time avoid the reduction of structural life caused by repeated force at the same axis position.

[0046] Furthermore, the first wiring harness channel 3 is L-shaped. The L-shape of the first wiring harness channel in this embodiment aligns with the angle of the corner of the lower cover of the cable protection box, making it more suitable for practical engineering applications. It should be understood that the vertical and horizontal segments of the L-shape are not necessarily straight lines; a certain curvature can be used to transition between the vertical and horizontal segments to avoid stress concentration, damage to the vehicle's own structure, or damage to other parts within the vehicle.

[0047] Optionally, the upper cover and lower cover of the wire protection box are made of insulating materials, such as lightweight materials such as plastic. While ensuring that leakage of the wire harness will not cause electric shock and protecting the wire harness, they also have the advantages of being light and low cost.

[0048] The above-mentioned structures such as the upper cover and lower cover of the wire protection box can be integrally formed or non-integrated. This embodiment preferably adopts an integrally formed structure to improve structural stability, reduce the use of connectors, and simplify the overall structure.

[0049] The harness protection box includes an interconnected upper cover, a lower cover, a first harness channel, and a second harness channel. The first and second harness channels are formed by connecting the upper and lower covers. The lower cover is provided with an expansion component for securing external harnesses. The harness protection box includes at least two channels, the first harness channel and the second harness channel, for securing harnesses. These channels can guide, constrain, and protect the harnesses, and an expansion component is also provided for securing external harnesses. Therefore, the harness protection box has at least three wiring harness outlet directions, making it compatible with harnesses in different locations, with different requirements, and with different configurations, offering greater adaptability.

[0051] This embodiment provides a vehicle, which includes the wire harness protection box described in Example 1.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the technical solutions of the embodiments of the present invention.
