[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] The terms "first," "second," and the like in the specification and claims of the present invention are used to distinguish similar objects, and are not used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of the present invention can be implemented in an order other than that illustrated or described herein, and that the objects distinguished by "first," "second," and the like are generally of the same type, and do not limit the number of objects. For example, the first object can be one or more. In addition, the term "and / or" in the specification and claims indicates at least one of the connected objects, and the character " / " generally indicates that the objects connected are in an "or" relationship.

[0030] It should be understood that references throughout this specification to "some embodiments" mean that a particular feature, structure, or characteristic associated with an embodiment is included in at least one embodiment of the present invention. Therefore, the appearance of "in some embodiments" throughout this specification does not necessarily refer to the same embodiment. Furthermore, these particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0031] The following describes in detail a wiring harness fixing buckle and a vehicle provided by the present invention by listing specific embodiments.

[0032] Reference Figure 1 and Figure 2An embodiment of the present invention provides a wiring harness fixing buckle, comprising a body 1; a plug-in hole 10 arranged along a first direction is provided in the body 1, and the plug-in hole 10 is used to insert a fastener to connect the body 1 to the vehicle body; a locking portion 11 is provided on the hole wall of the plug-in hole 10, and the locking portion 11 is used to cooperate with the fastener to lock and fix the fastener in the plug-in hole 10, wherein the locking portion 11 can be movable relative to the hole wall to at least adjust the position of the locking portion 11 in the second direction so that the locking portion 11 is adapted to the fasteners of different diameters; the first direction intersects with the second direction.

[0033] Specifically, the wire harness fixing buckle includes not only the main body 1 but also a cable tie 2, which is connected to the main body 1. The main body 1 is used to connect to the vehicle body through fasteners, and the cable tie 2 is used to constrain the wire harness. The wire harness fixing buckle can be a non-detachable one-piece part, which is directly processed into the main body 1 and the cable tie 2 through an one-piece molding process. The wire harness fixing buckle can also be a detachable split part, in which the main body 1 and the cable tie 2 are two independent components, which are assembled and connected to form the wire harness fixing buckle. The one-piece wire harness fixing buckle has a simple and reliable structure, which is more conducive to controlling the processing cost of the wire harness fixing buckle and extending its service life. The split wire harness fixing buckle can disassemble and separate the main body 1 or the cable tie 2, making it easier to inspect and maintain it.

[0034] Cable ties 2 are used to restrain wire harnesses. Nylon or stainless steel cable ties can be used, and they have excellent corrosion resistance, aging resistance, and load-bearing capacity, meeting the needs of long-term bundling. Cable ties 2 are typically arranged in a ring-shaped structure, with the wire harness threaded through the ring-shaped cable ties 2 to achieve wire harness restraint. If the number of wire harnesses is large or the harness is thick, the cable ties 2 can be arranged in a larger ring structure. If the number of wire harnesses is small or the harness is thin, the cable ties 2 can be arranged in a smaller ring structure to achieve an effective restraint effect.

[0035] The body 1 is configured to connect to the vehicle body via fasteners. These fasteners include, but are not limited to, studs, bolts, and screws, and are positioned according to the specific location of the vehicle body, which is not a limitation in this embodiment. Specifically, the body 1 includes a plug-in hole 10 arranged along a first direction. The plug-in hole 10 is configured to receive the fastener. The shape of the plug-in hole 10 is configured based on the shape of the fastener. Typically, the fastener is cylindrical, so the plug-in hole 10 can also be configured as a cylindrical hole. The first direction is the axial direction of the plug-in hole 10. The fastener is inserted into the plug-in hole 10, and a connection hole is provided at a corresponding location on the vehicle body. One end of the fastener extends from the plug-in hole 10 and is inserted into the connection hole on the vehicle body. The other end of the fastener extends out of the plug-in hole 10 and is exposed. During connection, the fastener is tightened from the exposed portion of the fastener using an operating tool, thereby achieving a fixed connection between the fastener and the vehicle body. The length of the plug-in hole 10 along its axis should not exceed the length of the fastener to avoid affecting the connection between the fastener and the vehicle body.

[0036] The wall of the plug hole 10 is provided with a locking portion 11. The locking portion 11 engages with a fastener. After the locking portion 11 engages with the fastener, the fastener is locked and fixed within the plug hole 10, thereby achieving a fixed connection between the body 1 and the vehicle body through the fastener. The locking portion 11 is movable relative to the wall of the plug hole 10 to adjust at least its position in a second direction, allowing the locking portion 11 to accommodate fasteners of different diameters. The second direction intersects the first direction, such as when the angle between the second direction and the first direction is within a range of 70° to 110°. In this embodiment of the utility model, the second direction is perpendicular to the first direction, and the second direction is the radial direction of the plug hole 10. Thus, when the locking portion 11 moves relative to the wall of the plug hole 10, at least its position in the radial direction of the plug hole 10 can be adjusted. This allows the locking portion 11 to accommodate fasteners of different diameters, thereby enabling the wiring harness securing buckle to accommodate fasteners of different sizes.

[0037] In some embodiments, the locking portion 11 and the hole wall of the plug hole 10 are elastically integrated, and the hole wall of the plug hole 10 is part of the body 1. For example, the locking portion 11 and the body 1 can be made of polyamide (PA), polyolefin thermoplastic elastomer (TPO), thermoplastic polyester elastomer (TPEE), polyurethane thermoplastic elastomer (TPU), etc., and have a certain degree of deformation ability. When the locking portion 11 is subjected to the extrusion force when the fastener is inserted, it can move relative to the hole wall of the plug hole 10, so that the locking portion 11 can adapt to fasteners of different sizes. In other embodiments, the locking portion 11 is an independent component, and the locking portion 11 is hinged to the hole wall of the plug hole 10. When the locking portion 11 is subjected to the extrusion force when the fastener is inserted, the locking portion 11 can rotate relative to the hole wall of the plug hole 10, so that the locking portion 11 can adapt to fasteners of different sizes.

[0038] Assuming that the fastener used in this embodiment is a stud, and the locking portion 11 is movable relative to the insertion hole 10, when an M5 stud is inserted into the insertion hole 10, the diameter of the M5 stud is generally in the range of about 5 mm, and the extrusion force exerted on the locking portion 11 when the M5 stud is inserted is relatively small, and the locking portion 11 undergoes a small degree of deformation to adapt to the mating connection with the M5 stud; when an M6 stud is inserted into the insertion hole 10, the diameter of the M6 ​​stud is generally in the range of about 6 mm, and the extrusion force exerted on the locking portion 11 when the M6 ​​stud is inserted is relatively large, and the locking portion 11 undergoes a large degree of deformation to adapt to the mating connection with the M6 ​​stud.

[0039] Therefore, the wiring harness fixing buckle of the embodiment of the present invention can utilize the locking portion 11 to be movable relative to the hole wall of the plug-in hole 10, and the position of the locking portion 11 in the radial direction of the plug-in hole 10 can be adjusted at least, so that the wiring harness fixing buckle can match fasteners of different sizes and specifications, thereby helping to reduce the types of wiring harness fixing buckles used when fixing the wiring harness of the entire vehicle, controlling the cost of vehicle management and procurement, and facilitating vehicle production optimization.

[0040] In some optional embodiments, such as Figure 1 As shown, the width of the locking portion 11 gradually decreases in the direction approaching the center of the plug hole 10, so that the size of the connection part between the locking portion 11 and the body 1 is larger than the size of the connection part between the locking portion 11 and the fastener, so as to ensure the connection reliability between the locking portion 11 and the body 1, avoid the locking portion 11 from falling off under the action of the fastener, and thus help reduce the risk of failure of the wiring harness fixing buckle.

[0041] In some optional embodiments, such as Figure 2 As shown, a toothed structure 111 is provided on a side of the locking portion 11 facing away from the hole wall, and the toothed structure 111 engages with the thread to secure the fastener in the insertion hole 10. Specifically, in this embodiment, the surface of the fastener is provided with a thread, and the toothed structure 111 is embedded in the thread to achieve engagement between the toothed structure 111 and the thread. When the toothed structure 111 is in engagement with the thread, the fastener is locked and secured in the insertion hole 10.

[0042] In some optional embodiments, such as Figure 2 As shown, the tooth structure 111 is a multi-layer structure, and the multi-layer tooth structure 111 is arranged along the first direction, that is, the axial direction of the plug hole 10. The multi-layer tooth structure 111 can increase the friction between the tooth structure 111 and the fastener, thereby preventing the fastener from shaking and improving the reliability of the fastener and the locking portion 11. The number of layers of the tooth structure 111 can be set according to actual needs. In this embodiment, the number of layers of the tooth structure 111 can be set to 3 to 5 layers. Figure 2The diagram shows a three-layer structure of toothed structure 111. Each of the three layers of toothed structure 111 is embedded in the fastener's threads, connecting the locking portion 11 to the fastener. If the threads are short along the fastener's axis, fewer layers of toothed structure 111 can be used to facilitate machining. If the threads are long along the fastener's axis, more layers of toothed structure 111 can be used to effectively connect the locking portion 11 to the fastener.

[0043] In some optional embodiments, there are at least two locking parts 11, and the at least two locking parts 11 are evenly distributed around the first direction on the hole wall of the plug hole 10. Around the first direction, that is, the axial direction of the plug hole 10, the force on the locking part 11 and the fastener is more uniform, which helps to improve the reliability of the connection between the locking part 11 and the fastener. The number of locking parts 11 can be set according to actual connection needs. In this embodiment, the number of locking parts 11 is set to 4 to 6. Figure 1 The schematic diagram shows a configuration in which four locking portions 11 are evenly spaced along the circumference of the insertion hole 10, with the spacing between adjacent locking portions 11 being 90°. If six locking portions 11 are provided, the six locking portions 11 are evenly spaced along the circumference of the insertion hole 10, with the spacing between adjacent locking portions 11 being 60°. Furthermore, in this embodiment, an even number of locking portions 11 is provided to better distribute the force applied to each locking portion 11.

[0044] In some optional embodiments, such as Figure 1 As shown, the wall of the plug hole 10 is further provided with a limiting portion 12, which protrudes toward the center of the plug hole 10. The limiting portion 12 can be a protruding point-shaped structure, a strip-shaped structure, etc., and the specific structure is not limited in this embodiment. The limiting portion 12 is used to abut against the surface of the fastener to increase the friction between the fastener and the fastener, thereby limiting the movement of the fastener relative to the plug hole 10. Specifically, the limiting portion 12 can limit the circumferential movement of the fastener relative to the plug hole 10 to a certain extent, and can also limit the axial movement of the fastener relative to the plug hole 10 to a certain extent, thereby effectively improving the reliability of the fastener being locked and fixed in the plug hole 10.

[0045] In some optional embodiments, there are at least two limiting portions 12. A greater number of limiting portions 12 improves the fastener's position-limiting effect, and accordingly, the harness securing buckle becomes more difficult to manufacture. A smaller number of limiting portions 12 reduces the difficulty of manufacturing the harness securing buckle, but correspondingly, the fastener's position-limiting effect decreases. The number of limiting portions 12 can be the same as the number of locking portions 11, and the at least two limiting portions 12 are also evenly distributed along the circumference of the plug hole 10. The at least two limiting portions 12 and the at least two locking portions 11 are alternately arranged along the circumference of the plug hole 10 to enhance the fastener's position-limiting effect.

[0046] In some optional embodiments, such as Figure 1 As shown, the width of the limiting portion 12 gradually decreases along the direction close to the center of the plug hole 10, so that the size of the connection part between the limiting portion 12 and the body 1 is larger than the size of the contact part between the limiting portion 12 and the fastener. Figure 1 The diagram in FIG. 1 shows a schematic diagram of the limiting portion 12 in the shape of a triangular prism. Of course, the limiting portion 12 can also have other structural shapes, which are not limited to this embodiment. The limiting portion 12 is arranged in the above manner to ensure the reliability of the connection between the limiting portion 12 and the body 1 and prevent the limiting portion 12 from falling off due to the action of the fastener.

[0047] In some optional embodiments, the surface of the limiting portion 12 in contact with the fastener can be set to an arc surface, and the curvature of the arc surface is set with reference to the curvature of the fastener surface, so that the limiting portion 12 is fully in contact with the surface of the fastener, thereby achieving a more effective limiting effect.

[0048] In some optional embodiments, the main body 1 includes a bottom surface 13, which is used to abut against the vehicle body to improve the stability and reliability of the connection between the wiring harness fixing buckle and the vehicle body. The locking portion 11 is arranged on the side of the hole wall of the plug hole 10 close to the bottom surface 13 to improve the stability of the fastener after locking and fixing.

[0049] The utility model also provides a vehicle, comprising any one of the aforementioned wiring harness fixing buckles.

[0050] Specifically, vehicles include both fuel vehicles and electric vehicles. The vehicles use the wire harness fixing buckles of the aforementioned embodiments. The wire harness fixing buckles can match fasteners of different sizes and specifications, thereby helping to reduce the types of wire harness fixing buckles used when fixing the wiring harness of the entire vehicle, controlling the cost of vehicle management and procurement, and facilitating vehicle production optimization.

[0051] Finally, it should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or terminal device that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or terminal device. In the absence of further limitations, an element defined by the phrase "comprising a ..." does not exclude the presence of additional identical elements in the process, method, article, or terminal device that includes the element.
