Description

Technical Field

[0001] The present disclosure relates to the field of automobile technology, and in particular to the technical field of automobile accessories. Background Art

[0002] With the rapid development of the automobile industry, the number of wiring harness loops and wiring harness connectors on automobiles is also increasing. In order to improve the reliability of the use of wiring harnesses and wiring harness connectors, it is generally necessary to fix the wiring harnesses and wiring harness connectors relative to the vehicle. The traditional setting is generally to open fixing holes on the body and fix the wiring harnesses and wiring harness connectors at the fixing hole positions respectively. However, when the number of wiring harnesses and wiring harness connectors increases, it will lead to insufficient layout space in the vehicle, and too many fixing holes on the body will also affect the strength of the body. Summary of the invention

[0003] The present disclosure provides a wiring harness fixing device and a vehicle which can simultaneously connect a wiring harness and a wiring harness connector, thereby avoiding providing too many fixing holes on a vehicle body and thus affecting the strength of the vehicle body.

[0004] According to one aspect of the present disclosure, there is provided a wire harness fixing device, wherein the wire harness fixing device comprises:

[0005] Fixed part;

[0006] Connecting part;

[0007] A wiring harness connector, the wiring harness connector is connected to the connecting portion, and the wiring harness connector has a plug-in interface;

[0008] A mounting seat, a first end of which is sandwiched between the fixing portion and the connecting portion;

[0009] A wire locking portion is arranged at the second end of the mounting seat, and the wire locking portion has a ring opening for fixing the wire harness, and the central axis of the ring opening is parallel to the insertion direction of the plug interface.

[0010] In the present scheme, through this arrangement, the wire harness fixing device can utilize the fixing part to be fixed in a preset position, and then utilize the connecting part and the wire lock part to simultaneously fix the wire harness connector and the wire harness, that is, only one mounting hole is required to achieve the purpose of fixing the wire harness and the wire harness connecting end, thus saving the number of mounting holes; at the same time, the wire lock part has a ring opening for fixing the wire harness, and the connecting end of the wire harness can be plugged in through the plug-in interface of the wire harness connector. Combined with the extended arrangement of the mounting seat, the wire harness is fixed to form a "U" shape, thus avoiding mutual interference between the wire harness and the wire harness connecting end, and also making the overall layout more neat and saving space.

[0011] According to another aspect of the present disclosure, a vehicle is provided, which includes the wire harness fixing device as described above.

[0012] In this solution, by applying the above-mentioned wiring harness fixing device to the vehicle, the problem that too many installation points need to be set up inside the vehicle when the number of wiring harnesses and wiring harness connectors in the vehicle continues to increase can be better solved.

[0013] It should be understood that the content described in this section is not intended to identify the key or important features of the embodiments of the present disclosure, nor is it intended to limit the scope of the present disclosure. Other features of the present disclosure will become easily understood through the following description. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The following is a description of exemplary embodiments of the present disclosure in conjunction with the accompanying drawings, including various details of the embodiments of the present disclosure to facilitate understanding, which should be considered as merely exemplary. Therefore, it should be recognized by those of ordinary skill in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present disclosure. Similarly, for the sake of clarity and conciseness, descriptions of well-known functions and structures are omitted in the following description.

[0020] This embodiment provides a vehicle (not shown in the figure), which includes but is not limited to electric vehicles, hybrid vehicles, and fuel vehicles. The model of the vehicle can be a sedan, SUV, off-road vehicle, station wagon, MPV, pickup truck, etc.

[0021] In this embodiment, a vehicle includes a chassis (not shown) and a wiring harness fixing device 1, and a mounting hole is opened on the chassis of the vehicle. The wiring harness fixing device 1 includes a fixing portion 20, and the wiring harness fixing device 1 is specifically fixed in the mounting hole through the fixing portion 20. Specifically, as Figure 1 and Figure 2As shown, in this embodiment, the fixing portion 20 of the wire harness fixing device 1 is a buckle structure, which can be elastically deformed, and the fixing portion 20 can be fixedly clamped in the mounting hole under the action of external force to prevent the entire wire harness fixing device 1 from being separated from the chassis of the vehicle. In other embodiments, the fixing portion 20 can also adopt other existing structures that can be adapted to the mounting hole, which will not be described in detail.

[0022] In addition, if Figure 1 , Figure 2 and Figure 4 As shown, the wire harness fixing device 1 includes a connecting portion 10, a mounting seat 30, a wire lock portion 40 and a wire harness connector 60 in addition to the fixing portion 20. The fixing portion 20 and the connecting portion 10 are both arranged at the first end position of the mounting seat 30, and are respectively arranged on two opposite sides of the mounting seat 30, that is, the first end of the mounting seat 30 is clamped between the fixing portion 20 and the connecting portion 10, the fixing portion 20 is used to cooperate with the mounting hole on the chassis to fix the wire harness fixing device 1, and the connecting portion 10 is used to connect the wire harness connector 60 to achieve the fixing of the wire harness connection end 71.

[0023] The harness connector 60 is connected to the connecting portion 10, and has a plug interface 61. The harness connector 60 can use the plug interface 61 to connect and fix the harness connection end 71, wherein the insertion direction L of the plug interface is the connection direction between the harness connector 60 and the harness connection end 71, that is, the insertion direction of the harness connection end 71. In addition, the wire lock portion 40 is disposed at the second end of the mounting seat 30, and the wire lock portion 40 has a ring opening 43 for fixing the harness 70, and the central axis corresponding to the ring opening 43 is parallel to the insertion direction L of the plug interface.

[0024] Through this arrangement, the wire harness fixing device 1 can be fixed on the chassis of the vehicle by using the fixing portion 20, and then the connecting portion 10 and the wire lock portion 40 can be used to simultaneously fix the wire harness connection end 71 and the wire harness 70, that is, only one mounting hole needs to be opened on the chassis to achieve the purpose of fixing the wire harness 70 and the wire harness connection end 71, saving the number of mounting holes; at the same time, the wire lock portion 40 has a ring opening 43 for fixing the wire harness 70, and the wire harness connection end 71 can be plugged through the plug-in interface 61 of the wire harness connector 60, combined with the extended arrangement of the mounting seat 30, so that the wire harness 70 is fixed to form a "U" shape (such as Figure 4 As shown), interference between the wire harness 70 and the wire harness connection end 71 is avoided, and the overall layout is also made neater and space is saved.

[0025] However, it should be noted that in the present invention, the parallel setting between the center axis corresponding to the ring 43 and the insertion direction L of the plug-in interface does not mean absolute parallelism. In practical applications, as long as a roughly parallel setting can be achieved, that is, as long as the wiring harness 70 is fixed, the angle formed between the center axis and the insertion direction will not cause mutual interference between the wiring harness 70 and the wiring harness connection end 71. Generally speaking, an angle of 0-5 degrees can be regarded as a parallel setting in the present invention because it is visually considered to be roughly parallel.

[0026] In this embodiment, the wiring harness connector 60 and the connecting portion 10 are specifically detachably connected. Compared with the fixed connection method, the detachable connection can facilitate the replacement of the wiring harness connector 60. The user can replace the corresponding wiring harness connector 60 according to the model of the wiring harness connecting end 71, so that the wiring harness fixing device 1 can be adapted to vehicles of different models or other wiring harness carriers. At the same time, the detachable connection is more convenient in processing, avoiding the complexity of the production mold, and the assembly sequence can also be adjusted in time according to actual needs. For example, the wiring harness connecting end 71 is first connected to the wiring harness connector 60, and then the whole is connected to the connecting portion 10, which is more flexible in assembly and disassembly. However, in other alternative embodiments, the wiring harness connector 60 and the connecting portion 10 can also be a non-detachable fixed connection or an integral molding.

[0027] Furthermore, if Figure 1 and Figure 2 As shown, a sliding track 11 is provided on the connecting portion 10 of the wiring harness fixing device 1, and the wiring harness connector 60 is specifically slidably connected to the connecting portion 10 via the sliding track 11, and the direction of the mutual sliding is consistent with the insertion direction L of the plug interface. Through this arrangement, the connecting portion 10 is slidably connected to the wiring harness connector 60 via its sliding track 11, which simplifies the installation steps of the wiring harness connector 60 relative to the connecting portion 10, and also ensures the stability of the wiring harness connector 60 relative to the connecting portion 10; in addition, the specific structure of the wiring harness connector 60 can be adjusted according to actual needs, or other existing sliding connection methods can be selected as needed. As long as the wiring harness connector 60 is provided with a structure that slides with the sliding track 11, the wiring harness connector 60 can be connected using the connecting portion 10. In addition, as Figure 1 As shown, the wiring harness connector 60 of the wiring harness fixture 1 is provided with a groove structure 62 at the position used for sliding with the connecting portion 10, and the groove structure 62 is engaged with the sliding track 11 on the connecting portion 10 to limit the relative movement of the wiring harness connector 60 and the connecting portion 10 in the non-sliding direction. It can be understood that, as Figure 1As shown, the wiring harness fixing device 1 utilizes its groove structure 62 to cooperate with the sliding track 11 on the connecting part 10 along the insertion direction L of the plug-in interface. When the two are connected with each other, the groove mechanism can wrap the sliding track 11, so that the wiring harness connector 60 and the connecting part 10 can only move relative to each other along the insertion direction L of the plug-in interface, thereby avoiding relative movement between the wiring harness connector 60 and the connecting part 10 in other directions, further ensuring the stability of the wiring harness connector 60 relative to the connecting part 10, and improving the reliability of the use of the wiring harness fixing device 1.

[0028] like Figure 2 As shown, a limiting protrusion 12 is also provided on the surface of the connection part 10 of the wiring harness fixture 1. When the wiring harness connector 60 is slidably connected to the connection part 10, the limiting protrusion 12 can limit the relative movement of the wiring harness connector 60 and the connection part 10 in the sliding direction. For example, a limiting groove can be provided on the surface of the wiring harness connector 60. When the wiring harness connector 60 and the connection part 10 are in the sliding process, the limiting protrusion 12 is squeezed so that the limiting protrusion 12 is slightly deformed. When the wiring harness connector 60 and the connection part 10 slide into place, the limiting protrusion 12 cooperates with the limiting groove on the wiring harness connector 60, thereby limiting the relative movement of the wiring harness connector 60 and the connection part 10 in the sliding direction. Through this arrangement, the stability of the wiring harness connector 60 and the connection part 10 in the connected state can be effectively improved, and the wiring harness connector 60 and the connection part 10 can be prevented from sliding relative to each other during the use of the wiring harness fixture 1, thereby affecting its normal use. In other embodiments, other existing limiting structures may also be used to limit the relative movement of the wiring harness connector 60 and the connecting portion 10 in the sliding direction.

[0029] It should be noted that the sliding connection provided in this embodiment is only one of the detachable connection modes between the wiring harness connector 60 and the connecting portion 10. In other alternative embodiments, the wiring harness connector 60 and the connecting portion 10 may also be detachably connected in other ways existing in the prior art, such as snap connection, threaded connection, etc.

[0030] like Figure 1 , Figure 2 and Figure 3As shown, the mounting seat 30 of the wire harness fixture 1 is a plate-like structure, and the fixing portion 20 and the connecting portion 10 are respectively arranged on two opposite sides of the mounting seat 30, and the fixing portion 20 and the connecting portion 10 are arranged opposite to each other on the mounting seat 30. Through this arrangement, the mounting seat 30 has enough space on its two opposite sides to install the fixing portion 20 and the connecting portion 10, and the installation is more stable, further improving the fixing effect of the wire harness fixture 1; in addition, the fixing portion 20 and the connecting portion 10 are arranged opposite to each other on the mounting seat 30, so that the positions of the fixing portion 20 and the connecting portion 10 are more concentrated, and the overall strength of the wire harness fixture 1 is higher.

[0031] As mentioned above, the wire harness fixture 1 can be fixed on the chassis of the vehicle through the fixing portion 20, wherein the fixing portion 20 is used to be installed on a mounting surface, which is the plane where the chassis of the vehicle is located. At this time, the plane where the plate-like structure in the mounting seat 30 is located is arranged parallel to the mounting surface. Through this arrangement, when the entire wire harness fixture 1 is installed on a mounting surface through the fixing portion 20, the plane where the plate-like structure in the mounting seat 30 is located is parallel to the mounting surface to ensure the neatness of the overall layout, thereby avoiding interference of the wire harness fixture 1 with other components.

[0032] like Figure 3 As shown, the harness fixing device 1 also includes a reinforcing rib 50, which is a rib structure. The reinforcing rib 50 is arranged on the surface of the mounting seat 30, and the extension direction of the reinforcing rib 50 is consistent with the extension direction of the mounting seat 30. By arranging the reinforcing rib 50 on the surface of the mounting seat 30 in the same direction as the extension direction of the mounting seat 30, the mounting seat 30 is partially reinforced to avoid the wire harness 70 and the wire harness connector 60 from simultaneously applying a force to the mounting seat 30, resulting in insufficient strength of the mounting seat 30, deformation or breakage, etc. The reinforcing rib 50 is specifically arranged on the surface of the mounting seat 30 to expand the reinforcing area and reinforcing effect of the reinforcing rib 50 on the mounting seat 30.

[0033] like Figures 1 to 4As shown, the wire lock part 40 of the wire harness fixing device 1 includes a locking structure 41 and a strap 42. The locking structure 41 is arranged at the second end of the mounting seat 30. The first end of the strap 42 is fixed on the locking structure 41. The second end of the strap 42 passes through the locking structure 41 to form a ring 43 for fixing the wire harness 70. The locking structure 41 can lock the strap 42. Through this arrangement, the locking structure 41 is arranged at the second end of the mounting seat 30, and the strap 42 is used to pass through the locking structure 41 to form a ring 43 for fixing the wire harness 70. On the basis of stable fixation, the structure is simpler and the operation is more convenient; at the same time, the strap 42 is locked by the locking structure 41, which further strengthens the fixation of the wire harness 70 and prevents the wire harness 70 from being easily loosened. It should be noted that, regarding the locking of the strap 42 by the locking structure 41, other locking structures and locking methods existing in the prior art can be adopted, which will not be repeated.

[0034] In this embodiment, the fixing part 20, the connecting part 10, the mounting seat 30 and the wire lock part 40 of the wire harness fixing device 1 are all one-piece structures, which are more convenient in processing and manufacturing, and have high production efficiency when the mold is fixed, which is conducive to wide production and promotion. Among them, the material of the one-piece structure is polyamide 66, which makes it have high mechanical strength, good durability, and high tensile and compressive strength. However, in other alternative embodiments, the components in the wire harness fixing device 1 can be formed separately and then assembled, without any fixing restrictions, and the material of the wire harness fixing device 1 can also be adjusted according to actual needs.

[0035] In this embodiment, by applying the above-mentioned wiring harness fixture 1 to the vehicle, the problem that too many mounting holes need to be set inside the vehicle when the number of automobile wiring harnesses 70 and wiring harness connectors 60 continues to increase can be better solved. In addition, as mentioned above, in this embodiment, the wiring harness fixture 1 is installed on the chassis of the vehicle through the fixing part 20, and the chassis is provided with a mounting hole, and the fixing part 20 is fixed in the mounting hole. On the basis of fixing the internal wiring harness 70 and wiring harness connector 60 of the vehicle, the number of connection holes on the chassis of the vehicle body is reduced as much as possible, thereby increasing the strength of the chassis as much as possible. However, in other alternative embodiments, mounting holes can also be opened in other parts of the vehicle, and the wiring harness fixture 1 can be installed in other parts of the vehicle, so as to avoid opening too many mounting holes in other parts of the vehicle and reducing the structural strength of the part.

[0036] The wire harness fixing device 1 of the present invention is not limited to being used on vehicles, but can also be applied to other equipment or devices with dense wire harnesses or the same wiring requirements, such as machine tools and the like.

[0037] In the description of this embodiment, it should be understood that the terms "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc. indicate the orientation or positional relationship of the device or element in normal use, which is only for the convenience of describing this embodiment and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation at any time, and therefore should not be understood as a limitation of the present disclosure in this regard.

[0038] The above specific implementations do not constitute a limitation on the protection scope of the present disclosure. It should be understood by those skilled in the art that various modifications, combinations, sub-combinations and substitutions can be made according to design requirements and other factors. Any modification, equivalent substitution and improvement made within the spirit and principle of the present disclosure shall be included in the protection scope of the present disclosure.
