Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts, and in particular to a wiring harness buckle, a vehicle sheet metal connection structure and a vehicle. Background Art

[0002] There are many wiring harnesses in the vehicle, some of which are arranged in the gap between the sheet metal and the interior parts. For example, the wiring harness at the door sill of the vehicle is arranged between the sheet metal and the interior parts. The wiring harness is usually fixed to the sheet metal by a wiring harness clip. Specifically, the wiring harness clip is clamped to the sheet metal and confines the wiring harness to the gap between the sheet metal and the wiring harness clip. For example, the wiring harness clip presses the wiring harness onto the sheet metal, and then the interior parts are clamped and installed to the sheet metal, thereby covering the wiring harness and the wiring harness clip.

[0003] However, this arrangement requires that the interior parts and the harness clips be removed in turn when the harness is maintained. The maintenance operation is cumbersome, affecting the repair efficiency. It may also lead to reliability risks in the connection between the harness clip and the sheet metal and the connection between the interior parts and the sheet metal, as well as the risk of wear on the sheet metal surface, such as the risk of paint peeling. In addition, the total number of connection structures on the sheet metal used to connect with the harness clips and the interior parts is relatively large. Not only is the processing cost of the sheet metal relatively high, but the space occupied by these connection structures is also large, which is not conducive to the miniaturization design of the space between the interior parts and the sheet metal.

[0033] like Figures 1 to 4 As shown, in the first aspect, the utility model provides a wiring harness buckle, including a first slot structure 100 and a clamping portion 200, the first slot structure 100 is provided with a clamping portion 200 on the slot wall structures 120 corresponding to the two ends of the slot 110 along the width direction of the slot 110, respectively, the clamping portion 200 is used to clamp with the clamping fitting portion 510 of the vehicle's interior trim 500, and the end of the wiring harness buckle away from the slot 110 is used to connect with the vehicle's sheet metal 600.

[0034] It should be noted that the first slot structure 100 is provided with a wire harness slot that runs through the extension direction of the wire harness 700, and the wire harness 700 is inserted into the wire harness slot through the slot opening 110 of the wire harness slot; "the slot wall structure 120 corresponding to the two ends of the first slot structure 100 along the width direction of the slot opening 110" is used to enclose the left and right slot walls of the wire harness slot. This specification will take the wire harness buckle used in the vehicle sheet metal connection structure as an example to illustrate the content of the utility model. Specifically, the wire harness buckle is used to install the wire harness 700, and is also used to install the wire harness 700 and the interior trim 500 on the sheet metal 600. Figure 1 and Figure 2 The figure shows the case where the vehicle sheet metal connection structure is located at the side door sill of the vehicle, that is, the wire harness buckle is used to connect the sheet metal 600 and the interior decoration 500 at the side door sill. However, it should be understood that it can also be used in other similar occasions without violating the design concept of the utility model, for example, the sheet metal 600 and the interior decoration 500 can be other structures to be connected.

[0035] The way in which the harness buckle is connected to the sheet metal 600 of the vehicle is not limited, and relevant technologies may be used. For example, the harness buckle includes a substrate 400, a first surface of the substrate 400 is attached to and connected to the sheet metal 600, and the first slot structure 100 and the clamping portion 200 are both located on the second surface of the substrate 400 away from the sheet metal 600.

[0036] In this embodiment, the first slot structure 100 is provided with a snap-fitting portion 200 on the slot wall structure 120 at both ends of the slot opening 110 thereof in the width direction. The snap-fitting portion 200 is used to snap-fit ​​and connect with the snap-fitting mating portion 510 of the vehicle's interior trim 500. The end of the wiring harness buckle that is away from the slot opening 110 of the first slot structure 100 is used to connect with the vehicle's sheet metal 600. That is, the interior trim 500 is connected to the sheet metal 600 through the wiring harness buckle. In this way, the interior trim 500 can be prevented from being directly connected to the sheet metal 600 at the wiring harness buckle, and the total number of connection structures on the sheet metal 600 for installing the wiring harness 700 and the interior trim 500 and the corresponding space occupancy can be reduced to a certain extent. , so that the space between the interior decoration part 500 and the sheet metal 600 can be used more for arranging the wiring harness, with a high space utilization rate, which is conducive to the miniaturized design of the space between the sheet metal 600 and the interior decoration part 500; at the same time, since the opening direction of the slot 110 of the first slot structure 100 points to the interior decoration part 500, the slot 110 of the first slot structure 100 can be exposed by removing the interior decoration part 500, so that the components in the first slot structure 100, such as the wiring harness 700, can be maintained, avoiding frequent disassembly of the wiring harness buckles, which can improve the disassembly and assembly efficiency, and is conducive to reducing the processing cost of the sheet metal 600 and the risk of surface wear caused by repeated disassembly and assembly (such as causing reliability risks such as paint peeling). Furthermore, the two clamping parts 200 are located on the groove wall structures 120 corresponding to the two ends of the first clamping groove structure 100 along the width direction of the groove opening 110 thereof, which can ensure the stability of the clamping of the interior decoration 500 with the wire harness buckle, ensure the reliability of the connection between the interior decoration 500 and the sheet metal 600 via the wire harness buckle, and also help to ensure the gap between the interior decoration 500 and the wire harness 700, and avoid the interior decoration 500 from breaking the wire harness 700, resulting in functional loss. In addition, the structural compactness of the wire harness buckle can be improved, which is conducive to further improving the space utilization between the interior decoration 500 and the sheet metal 600, and is conducive to further miniaturization of the space between the sheet metal 600 and the interior decoration 500. In general, the wiring harness buckle of the utility model can be used to install the wiring harness 700, and can also be used to connect the interior decoration part 500 and the sheet metal 600, which can improve the convenience of disassembly and assembly of the wiring harness 700, and has a compact structure. The connection reliability between the interior decoration part 500 and the sheet metal 600 is relatively high, which can improve the space utilization between the interior decoration part 500 and the sheet metal 600 to a certain extent, and is conducive to the miniaturization design of the space between the sheet metal 600 and the interior decoration part 500.

[0037] like Figure 1 As shown, optionally, the clamping portion 200 includes a clamping block 210 , and the clamping block 210 has a first clamping surface 211 disposed toward the sheet metal 600 . When the clamping portion 200 is clamped and connected with the clamping fitting portion 510 , the first clamping surface 211 abuts against the clamping fitting portion 510 .

[0038] It should be noted that the specific structure of the snap-fitting portion 510 can be set according to the specific structure of the snap-fitting portion 200 .

[0039] For example, a clamping arm can be provided on the groove wall structure 120, and the clamping arm is extended in a direction away from the first surface of the substrate 400. The clamping block 210 is provided at the end of the clamping arm. The clamping mating part 510 includes a clamping socket provided on the side of the interior decoration part 500 facing the sheet metal 600. The clamping arm extends into the clamping socket and abuts against the end face of the clamping socket through the first clamping surface 211 (not shown in the diagram of this scheme).

[0040] like Figures 1 to 3 As shown, optionally, a limiting groove 130 is provided on the groove wall structure 120, the opening of the limiting groove 130 faces the interior decoration part 500, and the clamping block 210 is provided on the side wall of the limiting groove 130; the snap-fitting part 510 includes a connecting column 511 and a snap-fitting protrusion 512 provided at the end of the connecting column 511, and the snap-fitting protrusion 512 is used to be inserted into the limiting groove 130 to engage with the clamping block 210.

[0041] Specifically, the limiting groove 130 is spaced apart from the inner wall surface of the groove wall structure 120, and the clamping block 210 is disposed on the side wall of the limiting groove 130 along the groove width direction. The top end of the groove wall structure 120 is the end close to the interior decoration 500, and the limiting groove 130 is usually disposed at the top end of the groove wall structure 120, and the opening of the limiting groove 130 faces the interior decoration 500.

[0042] In this way, the clamping block 210 is arranged on the side wall of the limiting groove 130, that is, the snap-fitting part 510 of the interior decoration component 500 needs to be inserted into the limiting groove 130 to snap-fit ​​with the clamping block 210. The side wall of the limiting groove 130 can form a limit on the snap-fitting part 510 to a certain extent, avoiding the interior decoration component 500 from squeezing the wiring harness during snap-fitting, improving the snap-fitting reliability of the snap-fitting part 200 and the snap-fitting part 510, and facilitating the structural setting of the snap-fitting part 510 on the interior decoration component 500. When performing the connection operation between the interior decoration component 500 and the wiring harness buckle, it is convenient to position the snap-fitting protrusion 512 through the limiting groove 130, which facilitates the snap-fitting operation between the snap-fitting part 200 and the snap-fitting part 510.

[0043] In this embodiment, the side wall of the limiting groove 130 away from the inner wall surface of the groove wall structure 120 along the groove width direction is defined as the set side wall 131, and the "inner wall surface of the groove wall structure 120" refers to the side wall surface of the groove wall structure 120 used to enclose the wiring harness slot.

[0044] Optionally, a block 210 is provided on the side wall of the limiting groove 130 opposite to the set side wall 131 .

[0045] In this way, when the interior decoration component 500 and the wiring harness buckle are in a clamped state, the expansion force of the slot wall structure 120 of the first slot structure 100 along the width direction of its slot opening 110 can be used to improve the reliability of the clamping of the clamping block 210 and the clamping protrusion 512. After the interior decoration component 500 and the wiring harness buckle are released from the clamping, the expansion force of the slot wall structure 120 of the limiting slot 130 along the width direction of the slot opening 110 can increase the width of the slot opening 110 of the first slot structure 100 to a certain extent, making it easier for the wiring harness 700 to be placed into the first slot structure 100 or removed from the first slot structure 100 through the slot 110.

[0046] Of course, it should be understood that a block 210 can also be provided on the setting side wall 131 of the limiting groove 130. When the side wall of the limiting groove 130 opposite to the setting side wall 131 is provided with a block 210, the setting side wall 131 abuts against the side wall of the connecting column 511 away from the clamping protrusion 512.

[0047] Optionally, a guide surface structure 132 is provided at the top end of a set side wall 131 of at least one limiting groove 130 .

[0048] Specifically, the guide surface structure 132 can be a slope or a curved surface. When the interior decoration component 500 and the wiring harness buckle are connected, the guide surface structure 132 can contact the end of the connecting column 511 to guide the movement of the connecting column 511, thereby reducing the difficulty of assembling the interior decoration component 500 and the wiring harness buckle.

[0049] Optionally, a top end of a side wall of at least one limiting groove 130 is used to abut against the interior decoration component 500 when the engaging portion 200 is engaged with the engaging protrusion 512 .

[0050] like Figure 2 As shown, for example, it shows the situation where the top end of the set side wall 131 of the limiting groove 130 located on the left side is in contact with the interior decoration part 500.

[0051] like Figure 1 and Figure 2 As shown, a reinforcing portion 513 is disposed on the connecting column 511 , and the side wall of the limiting groove 130 on the right side opposite to the set side wall 131 abuts against the corresponding reinforcing portion 513 .

[0052] In this way, by abutting the top end of the side wall of the limiting groove 130 with the interior decoration component 500, the maximum insertion depth of the connecting column 511 of the interior decoration component 500 can be limited during the process of inserting the connecting column 511 of the interior decoration component 500 into the limiting groove 130, thereby preventing the interior decoration component 500 from exerting pressure on the wiring harness 700 in the first slot structure 100, and, in combination with the clamping of the clamping block 210 and the clamping protrusion 512, the reliability of the clamping connection between the interior decoration component 500 and the wiring harness can be ensured.

[0053] In the above embodiment, it should be understood that the distances between the top ends of the two slot wall structures 120 of the first slot structure 100 and the sheet metal 600 may be inconsistent, so as to facilitate the wire harness 700 to enter or be taken out of the first slot structure 100 .

[0054] Optionally, the wire harness buckle further includes a second slot structure 300 , which is parallel to the axial direction of the first slot structure 100 , and is located outside a slot wall structure 120 of the first slot structure 100 .

[0055] It can be understood that the second slot structure 300 and the first slot structure 100 are both used to accommodate the wiring harness. The wiring harness slot of the second slot structure 300 and the wiring harness slot of the first slot structure 100 are both arc-shaped slots to match the circumferential surface of the wiring harness. The axial direction of the second slot structure 300 and the first slot structure 100 refers to the axial direction of the wiring harness slot they open, or the extension direction of the wiring harness in the wiring harness slot.

[0056] Specifically, the second slot structure 300 is parallel to the axial direction of the first slot structure 100. The second slot structure 300 can also be used to arrange the wire harness 700 or pipelines, etc. It can be put into use according to actual needs. For example, when the first slot structure 100 can meet the use requirements, the second slot structure 300 does not need to be put into use. When the wire harness 700 is added later, the newly added wire harness 700 can be fixed by the second slot structure 300, so that there is no need to operate the wire harness 700 in the first slot structure 100. The second slot structure 300 is located on the outside of a slot wall structure 120 of the first slot structure 100. The outside of the slot wall structure 120 is opposite to the inside of the slot wall structure 120, specifically referring to the side away from the slot wall structure 120 for enclosing the wire harness slot, so that the second slot structure 300 and the first slot structure 100 can be prevented from interfering with each other, or the second slot structure 300 can be prevented from affecting the clamping operation of the interior component 500.

[0057] Specifically, the second slot structure 300 is a C-shaped structure, which encloses the wire harness slot and has a notch for the wire harness 700 to pass through. At this time, the central angle of the wire harness slot of the second slot structure 300 is greater than 180° to prevent the wire harness from escaping from the wire harness slot. During use, the notch can be enlarged by elastic deformation of the C-shaped structure to allow the wire harness 700 to pass through the notch.

[0058] Optionally, the central angle corresponding to the wiring harness slot of the first slot structure 100 is smaller than the central angle corresponding to the wiring harness slot of the second slot structure 300. For example, the central angle corresponding to the wiring harness slot of the first slot structure 100 may also be greater than or equal to 180°. Since the first slot structure 100 has clamping parts 200 at both ends of the slot, when the clamping parts 200 are elastically clamped with the vehicle's interior trim 500, the slot can be tightened to prevent the wiring harness slot from escaping from the slot of the first slot structure 100.

[0059] Optionally, the opening of the second slot structure 300 faces the interior decoration component 500 .

[0060] by Figure 3 Taking the C-shaped structure located on the left side as an example, the opening direction of the C-shaped structure can be toward the left or upward. When the interior decoration component 500 is separated from the wiring harness buckle, the opening of the C-shaped structure is exposed, so that the wiring harness buckle and the sheet metal 600 do not need to be separated and the components in the C-shaped structure can be taken and placed.

[0061] Optionally, the wiring harness buckle also includes a substrate 400, which includes a first surface and a second surface arranged opposite to each other, the first surface of the substrate 400 is connected to the sheet metal 600, the second surface of the substrate 400 is connected to an end of the first slot structure 100 away from the slot 110, and the C-shaped structure is connected to at least one of the first slot structure 100 and the substrate 400.

[0062] At this time, the substrate 400 and the sheet metal 600 can have a larger contact surface, thereby improving the reliability of the connection between the wire harness buckle and the sheet metal 600. Figure 3 FIG. 4 shows a situation where the C-shaped structure is connected to the first slot structure 100 and the substrate 400 respectively.

[0063] At this point, it should be understood that weight-reducing holes can be provided on the wiring harness buckles without affecting the usage requirements, which will not be described in detail here.

[0064] Optionally, the second slot structure 300 is connected to the slot wall structure 120 , and along the circumference of the first slot structure 100 , the clamping portion 200 is located between the connection position between the second slot structure 300 and the slot wall structure 120 and the top of the slot wall structure 120 .

[0065] The first slot structure 100 is used to accommodate the wiring harness. The circumference of the first slot structure 100 refers to the circumference of the wiring harness slot it opens, or the circumference of the wiring harness located in the wiring harness slot. Figure 3As shown, the circumferential direction of the first slot structure 100 is a circular direction perpendicular to the X-axis, the C-shaped structure is located on the left side of the first slot structure 100, and the left-side clamping portion 200 is located between the connection position where the C-shaped structure is connected to the left-side slot wall structure 120 and the top of the left-side slot wall structure 120, for example, the left-side limiting groove 130 is located above the C-shaped structure.

[0066] At this time, on the one hand, the distance between the clamping part 200 corresponding to the side where the C-shaped structure is located and the sheet metal 600 is relatively large, which can reduce the size requirement of the clamping fitting part 510 corresponding to the clamping part 200, for example, the length requirement of the connecting column 511 of the left clamping fitting part 510 can be reduced; on the other hand, the second clamping groove structure 300 is connected to the groove wall structure 120 instead of being arranged at intervals, which is conducive to improving the structural compactness of the wiring harness buckle; on the other hand, since the occupied space of the groove cavity of the limiting groove 130 generally decreases from top to bottom, the clamping part 200 (that is, the clamping part 200 on the left side in the figure) is located above the connection position, which can To a certain extent, it can avoid the space occupation of the minimum wall thickness where the C-shaped structure and the first slot structure 100 are connected due to the setting of the limit groove 130 (the minimum wall thickness is usually located at the set surface, and the axis of the first slot structure 100 and the axis of the second slot structure 300 are located on the set surface). On this basis, the size requirement of the minimum wall thickness can be reduced to a certain extent, thereby improving the structural compactness of the wiring harness buckle to a certain extent, avoiding the wiring harness buckle from occupying more space, which is beneficial to improving the space utilization rate between the interior decoration part 500 and the sheet metal 600, and is beneficial to compressing the space requirement between the interior decoration part 500 and the sheet metal 600.

[0067] Optionally, a fixing arm 140 is protruding from at least one end of the first slot structure 100 along a set direction. The fixing arm 140 extends along the set direction and is used to connect to the wiring harness 700 , wherein the set direction is the axial direction of the first slot structure 100 .

[0068] In this embodiment, the axial direction of the first slot structure 100 refers to the axial direction of the wiring harness slot it opens, or the extension direction of the wiring harness 700 located in the wiring harness slot, that is, the X-axis direction in the figure. The first slot structure 100 is provided with fixed arms 140 protruding at both ends along the X-axis direction.

[0069] The fixing arm 140 can increase the contact surface between the wire harness buckle and the wire harness 700, and can also provide a connection basis for the wire harness 700 to be connected to the wire harness buckle. The specific connection method between the two is not limited.

[0070] Exemplarily, the wire harness 700 is fixed to the first slot structure 100 by an adhesive or a binding. Specifically, the wire harness 700 is fixed to the fixed arm 140 by an adhesive or a binding. The adhesive may be, for example, an adhesive tape, and the binding may be, for example, a cable tie, which facilitates the fixing of the wire harness 700 and has a simple fixing structure.

[0071] Optionally, a gap is left between the fixing arm 140 and the sheet metal 600 .

[0072] For example, the first surface of the substrate 400 is spaced apart from the fixing arm 140 in the up-down direction. The fixing arm 140 may be arranged corresponding to the bottom of the slot cavity of the first slot structure 100. In some cases, the fixing arm 140 may also be arranged corresponding to the connection position where the C-shaped structure is connected to the slot wall structure 120 in the above embodiment, so that the fixing arm 140 may be used to fix the wire harness 700 in the first slot structure 100, and may also be used to fix the wire harness 700 in the C-shaped structure.

[0073] In the above embodiment, optionally, the wire harness buckle is connected to the sheet metal 600 by snap-fitting, bonding, welding or by fasteners.

[0074] For example, the substrate 400 is bonded to the sheet metal 600. This can avoid drilling holes in the sheet metal 600, reduce the processing complexity of the sheet metal 600, reduce costs, reduce the possibility of surface wear of the sheet metal 600, and reduce the risk of paint peeling.

[0075] Secondly, the vehicle sheet metal connection structure provided by the utility model includes a sheet metal 600, an interior decoration component 500 and a wiring harness buckle as described in the above embodiment, the wiring harness buckle is located in the space surrounded by the sheet metal 600 and the interior decoration component 500, the first slot structure 100 of the wiring harness buckle is used to accommodate the wiring harness 700, the end of the wiring harness buckle facing away from the slot 110 of the first slot structure 100 is connected to the sheet metal 600, and the clamping portion 200 of the wiring harness buckle is clamped with the clamping mating portion 510 of the interior decoration component 500.

[0076] In a third aspect, the utility model provides a vehicle, which includes the vehicle sheet metal connection structure of the above embodiment.

[0077] The contents related to the vehicle sheet metal connection structure have been explained in the previous text. The vehicle sheet metal connection structure and the vehicle have the beneficial effects of the wiring harness buckle, which will not be repeated here.

[0078] Although the utility model is disclosed as above, the protection scope of the utility model is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the utility model, and these changes and modifications will fall within the protection scope of the utility model.
