Description

Technical Field

[0001] This application relates to the technical field of vehicle components, and particularly to a wire harness fixing device and a vehicle. Background Art

[0002] The wire harness in the vehicle movement section refers to a section of wire harness area that is frequently in motion states such as torsion, extrusion, and stretching during vehicle driving. These wire harness areas are usually located at the connection parts of the vehicle. These connection parts of the vehicle are constantly twisted and stretched during driving, and the corresponding wire harness areas will also deform and displace accordingly.

[0003] Traditional wire harnesses in the movement section are fixed by ordinary fastening ties. They are easily involved and damaged during movement, resulting in functional failure. Moreover, the wire harness depends on overly long wire harness branches to meet the requirements of the movement trajectory during movement. During the movement process, the movement trajectory of the wire harness is messy and is easily interfered with by other components in the environment, causing the wire harness to be worn through. During the fixing process of the wire harness and the tie, excessive tightening force will also cause damage to the wires, thereby affecting the circuit stability. Summary of the Utility Model

Detailed implementation manners

[0031] The following further elaborates on this application in conjunction with the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are merely used to explain the relevant utility model and do not limit the utility model. Additionally, it should be noted that for the sake of convenience in description, only the parts related to the utility model are shown in the drawings.

[0032] It should be noted that, without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. The following will detail this application with reference to the drawings and embodiments.

[0033] Figure 1 It is a schematic structural diagram of a wire harness fixing device provided by an embodiment of this application. Refer to Figure 1 , this wire harness fixing device specifically includes: a wire harness fixing part 1, an external connection part 2, and a lifting part 3 between the wire harness fixing part 1 and the external connection part 2.

[0034] Among them, the wire harness fixing part 1 includes a male part 11 of a snap fastener, a female part 12 of a snap fastener, and a wire harness guiding structure 13. The male part 11 and the female part 12 of the snap fastener are movably connected through a snap structure. The male part 11 of the snap fastener is connected to the first side of the wire harness guiding structure 13, and the female part 12 of the snap fastener is connected to the second side of the wire harness guiding structure 13;

[0035] The lifting part 3 is used to provide a gap between the wire harness fixing part 1 and the external connection part 2;

[0036] The external connection part 2 is used to connect with external components.

[0037] Among them, the male part 11 and the female part 12 of the snap fastener can be used in cooperation, capable of being buckled and opened with each other to achieve movable connection. The wire harness guiding structure 13 is used to fix the wire harness, and its extension direction is used to provide guidance for the wire harness, standardize the placement of the wire harness, and avoid the mixing and pulling between different wire harnesses.

[0038] Both sides of the wire harness guiding structure 13 are connected to the male part 11 and the female part 12 of the snap fastener respectively, that is, the first side of the wire harness guiding structure 13 is connected to the male part 11 of the snap fastener, and the second side of the wire harness guiding structure 13 is connected to the female part 12 of the snap fastener.

[0039] The elevation part 3 increases the distance between the wire harness and the mounting surface of the external component. When the moving component of the vehicle moves and drives the wire harness to move, it can ensure that the wire harness does not rub against the mounting surface. Through the setting of the elevation part 3, the separation of the wire harness from the external component can be achieved, ensuring that the wire harness is not scratched, thereby ensuring the stable transmission of the circuit.

[0040] Based on the above example, Figure 2 FIG. is a schematic structural diagram when another wire harness fixing device provided by an embodiment of the present application is buckled. Figure 3 FIG. is a schematic structural diagram when another wire harness fixing device provided by an embodiment of the present application is opened. Refer to Figure 2 and Figure 3 As shown in, the wire harness guiding structure 13 includes a first wire harness guiding structure 131, a second wire harness guiding structure 132 and a connecting rib 133. The male buckle 11 is connected to the first wire harness guiding structure 131, the female buckle 12 is connected to the second wire harness guiding structure 132, and the first wire harness guiding structure 131 and the second wire harness guiding structure 132 are connected by the connecting rib 133;

[0041] As Figure 2 shown, the wire harness guiding structure 13 forms a wire passing hole 4 when the male buckle 11 and the female buckle 12 are buckled, which is used to accommodate the target wire harness so that the target wire harness moves along the wire harness guiding structure 13 in a directional manner. The wire harness guiding structure 13 ensures the regularity of the movement track of the wire harness passing through the wire passing hole 4, so that the wire harness will not interfere with other components (such as external components or other wire harnesses) during the movement process, ensuring the safety of the wire harness movement.

[0042] It can be seen from this that the second wire harness guiding structure 132 is installed above the elevation part 3. When the buckle structure formed by the male buckle 11 and the female buckle 12 is buckled with each other, a cavity for the wire harness to pass through, that is, the wire passing hole 4, can be formed between the male buckle 11, the female buckle 12 and the wire harness guiding structure 13.

[0043] The wire harness guiding structure 13 is used to fix the wire harness. Its cross-sectional shape can be circular, square or other shapes. Its extension direction is used to provide guidance for the wire harness. The extension direction of the wire harness guiding structure 13 can be a linear structure as Figure 4 shown, or a special-shaped structure designed according to requirements. The front view of using the wire harness fixing device to fix the wire harness is as Figure 5 shown, and the schematic diagram of using the wire harness fixing device to fix the wire harness is as Figure 6 shown. It can be seen from this that the wire harness guiding structure 13 has a certain length, which can enable the wire harness branch to be in the wire passing hole 4, and drive the wire harness branch to move along the wire harness guiding structure 13 in a directional manner through the movement of the moving component of the vehicle.

[0044] Further, the first wire harness guiding structure 131 and the second wire harness guiding structure 132 may be symmetrical semicircular structures. In this case, the wire harness guiding structure 13 may be a circular structure to achieve the effect of fixing the wire harness.

[0045] Optionally, the shapes of the first wire harness guiding structure 131 and the second wire harness guiding structure 132 are determined by the shape of the wire harness to be fixed and are not limited to the above-mentioned semicircular structure. Therefore, the wire harness guiding structure 13 may also be a square structure or the like.

[0046] The connecting rib 133 is used to connect the first wire harness guiding structure 131 and the second wire harness guiding structure 132 , so that the first wire harness guiding structure 131 and the second wire harness guiding structure 132 can move relative to each other through the connecting rib 133 .

[0047] Further, the connecting rib 133 may be an arc-shaped structure, and the thickness of the connecting rib 133 is less than the thickness of the first wire harness guide structure 131 and the second wire harness guide structure 132. Optionally, the shape of the connecting rib 133 is not limited to an arc, as long as the first wire harness guide structure 131 can rotate therethrough.

[0048] It should be noted that the thickness of the connecting rib 133 is relatively thin, so that the connecting rib 133 has a large deformation amount and can withstand the rotation of the first wire harness guiding structure 131 .

[0049] The first wire harness guide structure 131 rotates in a range of 0°-180° through the connecting rib 133. It should be noted that the rotation range is set to 0° to 180°, and the structure of the first wire harness guide structure 131 is more stable. If the rotation range is too large, the first wire harness guide structure 131 may be broken at the connecting rib 133, or the wire harness may be unstable and the wire harness may easily shake in the wire harness guide structure 13.

[0050] The movable connection end of the male head of the snap buckle 11 is provided with a first inverted clip, the female head of the snap buckle 12 is set as a U-shaped structure, the movable connection end of the U-shaped structure is provided with a second inverted clip, and the first inverted clip and the second inverted clip form a buckle structure.

[0051] It can be understood that the female head 12 of the mother-and-child buckle is in a U-shaped structure, and the movable connecting end of the U-shaped structure is provided with a second inverted card. The female head 12 of the mother-and-child buckle is engaged with the first inverted card through the second inverted card, thereby realizing the clamping connection between the male head 11 of the mother-and-child buckle and the female head 12 of the mother-and-child buckle, and then, a wire hole 4 for allowing the wiring harness to pass can be formed between the male head 11 of the mother-and-child buckle, the female head 12 of the mother-and-child buckle and the wiring harness guide structure 13.

[0052] Based on the above example, Figure 2 As shown, the buckle portion between the first inverted clip and the second inverted clip forms an active cavity 5 of a preset size.

[0053] Optionally, a pressing portion may be provided at the top of the first inverted card, and providing the pressing portion can enable the operator to have a better user experience when opening the male buckle 11 of the snap fastener based on the first inverted card.

[0054] The movable cavity 5 enables the first inverted card to move flexibly within the movable cavity 5, so that the first inverted card can be opened or closed according to actual needs, facilitating the fixing of the wire harness. Moreover, the movable cavity 5 can be designed to a preset size according to requirements, providing a certain amount of movable space for wire harnesses of different volumes.

[0055] It should be noted that the female buckle 12 of the snap fastener has a U-shaped structure, and the two side edges of the U-shaped structure can use relatively soft materials, that is, the two side edges have a certain amount of deformation, facilitating the first inverted card to be pressed into the movable cavity to complete the snap connection with the second inverted card.

[0056] One end of the U-shaped structure close to the second wire harness guiding structure 132 can be regarded as a support plate. When the first inverted card is snap-connected to the second inverted card, one side of the first inverted card abuts against the support plate.

[0057] The support plate is provided at one end of the second wire harness guiding structure 132. The support plate 13 is used to play a better abutting role when the first inverted card 112 and the second inverted card are snapped together, preventing the first inverted card and the second inverted card from loosening after being snapped together, resulting in the first inverted card easily detaching from the second inverted card and causing the snap structure to open, and the first wire harness guiding structure 131 to be separated from the second wire harness guiding structure 132, and the fixed wire harness to fall off.

[0058] Optionally, a bent buffer portion is provided at the connection between the support plate and the second wire harness guiding structure 132.

[0059] It can be understood that the card mouths of the first inverted card and the second inverted card face in opposite directions so that the two can be snapped together.

[0060] After the wire harness is fixed in the wire passing hole 4 formed among the male buckle 11, the female buckle 12 of the snap fastener and the wire harness guiding structure 13 in the wire harness fixing portion 1, the first inverted card and the second inverted card are snapped together, so that the wire harness fixing portion 1 fixes the wire harness; when the wire harness needs to be taken out, the first inverted card and the second inverted card are opened from each other, causing the male buckle 11 of the snap fastener to be separated from the female buckle 12, realizing the opening of the wire harness fixing portion 1.

[0061] Based on the above example, referring to Figure 2 and Figure 3 , the external connection portion 2 includes a cable tie fixing head 21, cable tie teeth 22, and a cable tie fixing head skirt 23;

[0062] On the inner side wall of the skirt 23 of the cable tie fixing head, a cable tie fixing head 21 is fixedly installed. On both sides of the cable tie fixing head 21, there are cable tie teeth 22, and several limiting steps are arranged on the outer walls of the cable tie teeth 22. A contraction groove is provided on the cable tie fixing head 21.

[0063] One end of the external connection part 2 close to the elevation part 3 is the skirt 23 of the cable tie fixing head. A cable tie fixing head 21 is fixedly installed on the inner side wall of the skirt 23 of the cable tie fixing head. The cable tie fixing head 21 is inserted into a sheet metal hole on the mounting surface of the external component, so that the skirt 23 of the cable tie fixing head is in close contact with the external component, ensuring that the cable tie fixing head 21 is firmly installed in the sheet metal hole.

[0064] On both sides of the cable tie fixing head 21, there are cable tie teeth 22, and several limiting steps are arranged on the outer walls of the cable tie teeth 22. Through the frictional force generated between the cable tie teeth 22 and the inner wall of the sheet metal hole, the positioning of the cable tie fixing head 21 can be realized, and the firmness of the installation of the cable tie fixing head 21 can be increased by the arranged limiting steps.

[0065] When the cable tie fixing head 21 is inserted into a sheet metal hole on the mounting surface of the external component, the skirt 23 of the cable tie fixing head is in close contact with the mounting surface, which can ensure that the cable tie fixing head 21 is firmly installed in the sheet metal hole on the mounting surface. The cable tie teeth 22 on the cable tie fixing head 21 act on the inner wall of the sheet metal hole to realize the positioning of the cable tie fixing head 21. Different limiting steps of the cable tie teeth 22 can be adjusted to adapt to sheet metal holes of various thicknesses.

[0066] On the basis of the above example, the elevation part 3 includes a first adjustment part;

[0067] The first adjustment part is used to adjust the height of the elevation part 3 to provide intervals of various heights between the wire harness fixing part 1 and the external connection part 2.

[0068] Specifically, the first adjustment part can be a telescopic structure or other structures for changing the height of the elevation part 3. By adjusting the first adjustment part, the height of the elevation part 3 can be changed to isolate the wire harness fixed in the wire harness fixing part 1 from the external component connected to the external connection part 2 at different heights. It can also distinguish wire harnesses with different orientations through the wire harness fixing device with the elevation part 3 of different heights, avoiding mutual friction between wire harnesses.

[0069] It can be understood that if the wire harness fixing device A needs to provide a gap of at least a between the wire harness 1 and the external component, the lifting part 3 can be adjusted to a height of a through the first adjusting part of the wire harness fixing device A. Further, if the wire harness fixing device B near the wire harness fixing device A needs to provide a gap of at least a between the wire harness 2 and the external component, and the wire harness 1 and the wire harness 2 cross in space, it can be known that if the lifting part 3 is adjusted to a height of a through the first adjusting part of the wire harness fixing device B, it will cause wire entanglement and friction between the wire harness 1 and the wire harness 2. Therefore, the lifting part 3 can be adjusted to a height of a + b through the first adjusting part of the wire harness fixing device B, where b is the preset wire harness interval.

[0070] Based on the above example, the wire harness guiding structure 1 includes a second adjusting part;

[0071] The second adjusting part is used to adjust the size of the wire passing hole 4 formed when the male snap 11 and the female snap 12 are snapped together in the wire harness guiding structure 1.

[0072] Specifically, the sizes (such as diameters) and quantities of the wire harnesses that need to be fixed by the wire harness fixing device are different. Therefore, if the wire passing hole 4 formed when the male snap 11 and the female snap 12 are snapped together is a wire harness guiding structure 1 with a fixed size, the wire harnesses with too small sizes or too few quantities will shake in the wire passing hole 4 and cannot be effectively fixed, and the wire harnesses with too large sizes or too many quantities cannot be fixed in the wire passing hole 4. Therefore, the second adjusting part can be a telescopic structure or other structures for changing the size of the wire harness guiding structure 1. The size of the wire harness guiding structure 1 can be adjusted through the second adjusting part provided on the wire harness guiding structure 1, specifically the size of the wire passing hole 4 formed when the male snap 11 and the female snap 12 are snapped together in the wire harness guiding structure 1, so as to use wire harnesses with different sizes and quantities.

[0073] Further, the second adjusting part can be provided only in the middle of the first wire harness guiding structure 131 of the wire harness guiding structure 13. Since the second wire harness guiding structure 132 is fixed on the lifting part 3, it is not convenient to provide a second adjusting part in the middle for size adjustment.

[0074] Further, the second adjusting part can be provided on the first wire harness guiding structure 131 and the second wire harness guiding structure 132 of the wire harness guiding structure 13, and specifically can be provided on the side. In this way, the first wire harness guiding structure 131 and the second wire harness guiding structure 132 with the second adjusting part can still present a symmetrical structure.

[0075] In the above manner, a certain movement gap can be maintained between the wire harness and the wire harness guiding structure 13, ensuring that the wires will not be damaged due to extrusion and ensuring the stable transmission of the circuit. Moreover, the wire harness guiding structure 13 of the wire harness fixing portion 1 can be adapted to wire harness branches of different sizes, ensuring the adaptability of the assembly.

[0076] Based on the above example, as Figure 2 and Figure 3 shown, a first hole 6 can be provided on the elevation portion 3 to reduce the material used for the wire harness fixing device and achieve a lightweight structure.

[0077] When the height of the elevation portion 3 is greater than the preset height, a first number of first holes 6 are provided on the elevation portion 3; when the height of the elevation portion 3 is less than or equal to the preset height, a second number of first holes 6 are provided on the elevation portion 3. Among them, the first number is greater than the second number.

[0078] It can be understood that if the height of the elevation portion 3 is fixed, different types of wire harness fixing devices can be distinguished by the height, and the number of first holes can be distinguished by the preset height. When the height of the elevation portion 3 is greater than the preset height, it means that the overall size of the elevation portion 3 is larger. Therefore, more first holes 6 can be provided to reduce the material used, that is, a first number of first holes 6 are provided on the elevation portion 3. When the height of the elevation portion 3 is less than or equal to the preset height, it means that the overall size of the elevation portion 3 is smaller. Therefore, fewer first holes 6 can be provided to reduce the material used, that is, a second number of first holes 6 are provided on the elevation portion 3. The sizes of the first number and the second number can be determined according to actual needs and are not specifically limited in this embodiment.

[0079] Optionally, if the number of first holes 6 provided on the elevation portion 3 is fixed, the weight of the wire harness fixing device can be adjusted by setting different sizes and shapes of the first holes 6.

[0080] Based on the above example, in order to further reduce the material used for the wire harness fixing device and achieve a lightweight structure, a third number of second holes 7 can be provided on the wire harness fixing portion 1; a fourth number of third holes are provided on the external connection portion 2.

[0081] It can be understood that the sizes of the third number, the fourth number, the sizes and shapes of the second holes 7, and the sizes and shapes of the third holes can be set according to the specific requirements of the wire harness fixing device or according to the material reduction requirements, and are not specifically limited in this embodiment.

[0082] The wire harness fixing device provided by the embodiment of the present application fixes the wire harness through a wire harness fixing part, an external connection part, and a lifting part between the wire harness fixing part and the external connection part. The wire harness fixing part includes a male snap fastener, a female snap fastener, and a wire harness guiding structure. The male snap fastener and the female snap fastener are movably connected through a snap structure. The male snap fastener is connected to the first side of the wire harness guiding structure, and the female snap fastener is connected to the second side of the wire harness guiding structure. The lifting part is used to provide a gap between the wire harness fixing part and the external connection part. The external connection part is used to connect to an external component, achieving the effect of reducing the tightening force of the wire harness through the wire harness guiding structure and providing an orderly guide for the wire harness. The wire harness can be separated from other components through the lifting part, ensuring the stability and safety of the circuit.
