[0050] Reference below Figure 1-Figure 10 A wire harness fixing device 100 according to an embodiment of the present invention is described.

[0051] like Figure 1-Figure 10 As shown, a wire harness fixing device 100 according to an embodiment of the present invention includes: a base 10, a first fixing member 20 and a second fixing member 30, the first fixing member 20 is arranged on the base 10, the first fixing member 20 is provided with a first limiting structure 40 for fixing the first wire harness, the second fixing member 30 is arranged on the first fixing member 20, and the second fixing member 30 is provided with a second limiting structure 50 for fixing the second wire harness, and the limiting structure here can be a limiting hole, a limiting groove, etc., which can play a limiting role on the wire harness.

[0052] The fixing device of the embodiment of the present invention can fix two wiring harnesses at the same time, so there is no need to add another type of wiring harness buckle, which avoids the increase of the weight of the wiring harness. At the same time, it can reduce the number of holes opened on the sheet metal or the vehicle body, which can reduce damage to the vehicle body and improve the safety of the vehicle. In addition, it also simplifies the assembly process, making the fixing of the wiring harness more convenient and quick.

[0053] It should be noted that the fixed wiring harness here is not limited to the circuit wiring harness, but can also be a water pipeline.

[0054] In some embodiments, the first limiting structure 40 and the second limiting structure 50 are limiting holes or limiting grooves, that is, the first limiting structure 40 and the second limiting structure 50 can both be limiting holes, the first limiting structure 40 and the second limiting structure 50 can also both be limiting grooves, the first limiting structure 40 and the second limiting structure 50 can be one of a limiting hole and the other of a limiting groove, the first limiting structure 40 and the second limiting structure 50 have different shapes, the wiring harness is installed in the limiting hole, or the wiring harness is plugged into the limiting groove, so that the wiring harness fixing device 100 can simultaneously fix wiring harnesses of different cross-sectional shapes.

[0055] In some embodiments, one of the first limiting structure 40 and the second limiting structure 50 is square, and at least a portion of the other one of the first limiting structure 40 and the second limiting structure 50 is arc-shaped.

[0056] The square shape here means that when the limiting structure is a limiting hole, the limiting hole is a square hole, and when the limiting structure is a limiting groove, the limiting groove is a square groove; the at least part of the arc shape here means that when the limiting structure is a limiting hole, at least a part of the hole edge of the limiting hole is arc-shaped, and when the limiting structure is a limiting groove, at least a part of the hole edge of the limiting groove is arc-shaped. For example, the first limiting structure 40 can be a limiting hole, and the limiting hole is a square hole; the second limiting structure 50 can be a limiting hole, and at least a part of the hole edge of the limiting hole is arc-shaped. In this way, both square wire harnesses or flat wire harnesses and round wire harnesses can be fixed, meeting the placement requirements of wire harnesses or pipelines of different shapes.

[0057] like Figure 1 As shown, in some embodiments, the first limiting structure 40 is a first limiting hole, the second limiting structure 50 is a second limiting hole, and the first limiting hole and the second limiting hole have different shapes, so that the wire harness fixing device 100 can simultaneously fix wire harnesses with different cross-sectional shapes.

[0058] In some embodiments, the first fixing member 20 is movable relative to the base 10, and a first limiting structure 40 is defined between the first fixing member 20 and the base 10, the second fixing member 30 is movable relative to the first fixing member 20, and a second limiting structure 50 is defined between the second fixing member 30 and the first fixing member 20, and the first limiting structure 40 and the second limiting structure 50 have different shapes, so that the wiring harness fixing device 100 can simultaneously fix wiring harnesses and pipelines with different cross-sectional shapes.

[0059] Among them, the first fixing member 20 can be movable relative to the base 10, which can facilitate the placement of the wiring harness or pipeline in the first limiting structure 40, and can also adjust the size or shape of the first limiting structure 40, thereby meeting the placement requirements of wiring harnesses or pipelines of different sizes and shapes; the second fixing member 30 can be movable relative to the first fixing member 20, which can facilitate the placement of the wiring harness or pipeline in the second limiting structure 50, and can also adjust the size or shape of the second limiting structure 50, thereby meeting the placement requirements of wiring harnesses or pipelines of different sizes and shapes.

[0060] According to the wire harness fixing device 100 of the embodiment of the present invention, wire harnesses and pipelines of different cross-sectional shapes can be fixed at the same time, meeting the installation requirements of wire harnesses or pipelines of different sizes, and improving the adaptability of the fixing device; the overall structure is simple and compact, the production cost is low, and the space occupied by the fixing of the wire harness or pipeline can be reduced.

[0061] like Figure 1 As shown, in some embodiments, the first limiting hole is a square hole, so that the first limiting hole can be used to fix a wire harness with a square cross-section, such as a flexible flat cable (FFC). FFC is a new type of flexible flat cable made of PET insulating material and extremely thin flat copper wire, which is pressed together by automated equipment.

[0062] At least a portion of the edge of the second limiting hole is arc-shaped, so the second limiting hole can be used to fix wire harnesses or pipelines with a circular cross-section, such as water pipes, oil pipes, and some connecting wires that are wrapped and bundled with tape; of course, the second limiting hole can also be a square hole, and at least a portion of the edge of the first limiting hole can be arc-shaped.

[0063] Therefore, the wire harness fixing device 100 according to the embodiment of the present invention can fix square wire harnesses or flat wire harnesses, as well as circular wire harnesses, and can adjust the sizes of the first limiting structure 40 and the second limiting structure 50 according to the size of the wire harnesses to meet the placement requirements of wire harnesses or pipelines of different sizes and shapes.

[0064] In some embodiments, the first fixing member 20 and the base 10 are movably matched, such as rotating or sliding, so that the shape and size of the first limiting structure 40 can be adjusted to adapt to first wire harnesses of various sizes.

[0065] In some embodiments, the second fixing member 30 and the first fixing member 20 are movably matched, such as rotationally matched or slidingly matched, thereby adjusting the shape and size of the second limiting structure 50 to adapt to a variety of second wire harnesses of different sizes.

[0066] In some embodiments, the first fixing member 20 and the base 10 are slidably matched. Through the sliding cooperation between the two, the shape and size of the first limiting structure 40 can be adjusted, so that it can adapt to a variety of wire harnesses of different sizes, such as flat wire harnesses of different sizes, and the movement of the first fixing member 20 is more convenient, which can improve the efficiency of assembly adjustment.

[0067] In some embodiments, the second fixing member 30 and the first fixing member 20 are slidably matched. Through the sliding cooperation between the two, the shape and size of the second limiting structure 50 can be adjusted, so that it can adapt to a variety of wire harnesses of different sizes, such as circular wire harnesses of different diameters, and the movement of the second fixing member 30 is more convenient, which can improve the efficiency of assembly adjustment. The second fixing member 30 can be two simple arc structures, and the second limiting structure 50 is defined by the two arc structures approaching or moving away from each other. The second fixing member 30 can also be other structural forms.

[0068] like Figure 1 and Figure 2 As shown, in some embodiments, the first fixing member 20 has a first limiting section 21 and a second limiting section 22, and the first limiting section 21 is slidably matched with the base 10, thereby achieving the sliding fit between the first fixing member 20 and the base 10, and then the shape and size of the first limiting structure 40 can be adjusted, so as to adapt to a variety of wire harnesses of different sizes.

[0069] The second limiting section 22 is located on a side of the first limiting section 21 away from the base 10 (eg Figure 2 The upper side shown in the figure), and the second fixing member 30 cooperates with the second limiting section 22, so that the first limiting structure 40 and the second limiting structure 50 formed can be arranged in the direction away from the base 10, which is convenient for the installation of different wiring harness pipelines and can reduce the interference between different wiring harnesses. At the same time, the structure after installation is compact, which reduces the space occupied by the installation of the wiring harness pipeline.

[0070] like Figure 4 As shown, in some embodiments, the first limiting section 21 includes an insert plate 211 and a connecting plate 212, the insert plate 211 and the second limiting section 22 are arranged at intervals, one end of the insert plate 211 is connected to the second limiting section 22 through the connecting plate 212, the base 10 is defined with a first slide groove 11, the insert plate 211 slides with the first slide groove 11, and a first limiting structure 40 is defined between the connecting plate 212, the second limiting section 22 and the base 10, that is, there is a receiving groove 2011 between the first limiting section 21 and the second limiting section 22, because the insert plate 211 is inserted into the first slide groove 11, a part of the receiving groove 2011 can form the first limiting structure 40 or a part of the first limiting structure 40, thereby, through the sliding cooperation between the insert plate 211 and the first slide groove 11 on the base 10, the size of the first limiting structure 40 can be adjusted, the structure is simple, and the adjustment is convenient.

[0071] In some embodiments, the first fixing member 20 includes a limiting member 201, and the first limiting structure 40 with adjustable size is defined by the sliding cooperation between the plug plate 211 of the limiting member 201 and the first slide groove 11 on the base 10, and the overall structure is simple.

[0072] like Figure 2 As shown, in some embodiments, the first fixing member 20 includes two limiting members 201, each limiting member 201 extends along the length direction of the first slide slot 11, and the two limiting members 201 are arranged along the width direction of the first slide slot 11, as shown in FIG. Fig.10 As shown, the width of the first slide groove 11 is the same as the width of the two limiting members 201 , and the length of each limiting member 201 is the same as the length of the first slide groove 11 .

[0073] Each limiting member 201 has a first limiting section 21 and a second limiting section 22, and a receiving groove 2011 with an open end is defined between the first limiting section 21 and the second limiting section 22 of each limiting member 201, wherein the opening directions of the receiving grooves 2011 of the two limiting members 201 are opposite, thereby the two limiting members 201 slide relative to the first sliding groove 11 to define a first limiting structure 40 with adjustable size, which can increase the adjustable range of the first limiting structure 40 to meet the requirements of fixing wire harnesses of different sizes.

[0074] like Figure 6 and Fig.10 As shown, in some embodiments, the plug plate 211 has a first tooth portion 213, and the first slide groove 11 has a first groove 111. The first tooth portion 213 is snap-fitted with the first groove 111, thereby locking the position of the plug plate 211 in the first slide groove 11, and then locking the size of the first limiting structure 40, preventing the plug plate 211 from further sliding in the first slide groove 11, colliding or squeezing the wiring harness pipeline in the first limiting structure 40, and affecting the reliability of the wiring harness pipeline.

[0075] Of course, the first tooth portion 213 may also be arranged on the first sliding groove 11 , and the first groove 111 may be correspondingly arranged on the inserting plate 211 .

[0076] like Figure 6 As shown, in some embodiments, the inner wall surface of the first slide groove 11 is provided with a plurality of first ribs 112, and the plurality of first ribs 112 are arranged at intervals along the extension direction of the first slide groove 11, and a first groove 111 is defined between two connected first ribs 112, thereby forming a first groove 111 on the first slide groove 11, wherein an ejection port 60 is further provided on the base 10, and the ejection port 60 is located between two adjacent first ribs 112, and the ejection port 60 is correspondingly connected to the first groove 111, thereby facilitating the molding of the ribs in the first slide groove 11.

[0077] like Figure 2 As shown, in some embodiments, a plurality of first teeth 213 are provided on one side edge of the plug plate 211, and the plurality of first teeth 213 are arranged at intervals along the extension direction of the first slide groove 11, thereby forming the first tooth 213 on the first limiting section 21, and the first tooth 213 is located at the edge of the plug plate 211, and the first tooth 213 is easy to form. At this time, a plurality of first teeth 213 can be provided on the plug plate 211, and two first ribs 112 are provided in the first slide groove 11, thereby forming a first slide groove 11, which can not only realize the snap-fitting of the plug plate 211 with the first slide groove 11, but also facilitate the manufacturing and forming of the first fixing member 20 and the base 10.

[0078] like Figure 2 As shown, the first fixing member 20 includes two limiting members 201, and the two limiting members 201 have the same structure. The first limiting section 21 of each limiting member 201 can slide left and right on the base 10 along with the plug plate 211, and is fixed by the first groove 111 set in the first slide groove 11 to prevent the first limiting section 21 from falling off. The plug plate 211 can be fixed at any position of the first slide groove 11 to adjust the position of the connecting plate 212, and then adjust the size of the first limiting structure 40.

[0079] like Figure 2 As shown, in some embodiments, the second fixing member 30 includes an elastic member 31 and a locking member 32, the elastic member 31 is located on the side of the second limiting section 22 away from the first limiting section 21, and a second limiting structure 50 is defined between the elastic member 31 and the first fixing member 20, the locking member 32 cooperates with the elastic member 31, and the locking member 32 cooperates with the second limiting section 22 to limit the state of the elastic member 31, that is, to achieve locking of the position and shape of the elastic member 31.

[0080] It can be understood that the elastic member 31 is a deformable structural member, for example, a plastic material is used, one end of the elastic member 31 is fixed, and the other end is locked by a locking member 32, and when the locking member 32 moves relative to the second limiting section 22, the elastic member 31 can be deformed, the structure of the elastic member 31 can be adjusted, and the size and shape of the second limiting structure 50 can be changed; of course, the two ends of the elastic member 31 can also be locked by the locking member 32 respectively.

[0081] like Figure 3 and Figure 7 As shown, in some embodiments, the locking member 32 slides with the second limiting section 22 to drive the elastic member 31 to deform to change the shape of the second limiting structure 50, thereby being able to adapt to a variety of wire harnesses of different sizes, such as circular wire harnesses of different diameters, and the locking member 32 is easy to move, which can improve the efficiency of assembly and adjustment.

[0082] like Figure 2As shown, in some embodiments, the second limiting section 22 is defined by a second slide groove 221, and the locking member 32 includes a locking plate 321 and a locking hook 322. The locking plate 321 is slidably disposed on the second slide groove 221, one end of the locking hook 322 is connected to the locking plate 321, and the other end of the locking hook 322 extends out of the second slide groove 221, and the locking hook 322 cooperates with the elastic member 31. Therefore, the locking member 32 has a simple structure and is easy to move, which facilitates the cooperation of the locking member 32 with the second limiting section 22 and the elastic member 31.

[0083] like Figure 2 As shown, in some embodiments, the locking member 32 has a second tooth portion 323, and the second slide groove 221 has a second groove 222.
