Description

Technical Field

[0001] This application relates to the field of automotive wiring harness fixing technology, and more particularly to a wiring harness fixing device and an automobile. Background Technology

[0002] With the continuous development of automotive intelligence, there are more and more controllers in the car, which leads to increasingly complex wiring harnesses and thicker wires, occupying more space.

[0003] See CN217730374U, a wiring harness fixing mechanism and an automobile. The wiring harness fixing mechanism provided in this application includes a wiring harness fixing assembly, a connecting plate, and clamping members. The wiring harness fixing assembly includes a cable tie and a fixing seat. The cable tie is connected to the fixing seat and is used to fix the wiring harness. The fixing seat is rotatably connected to the connecting plate so that the cable tie is disposed on one side of the connecting plate and can rotate relative to the connecting plate to adjust the position of the wiring harness. The clamping members are connected to the side of the connecting plate away from the cable tie and can clamp the component to be fixed.

[0004] However, the fixed mechanism provided in document 1 occupies a large space in the Z direction, which will greatly reduce the activity space for the driver and passengers. Utility Model Content

[0005] This application provides a wiring harness fixing device and an automobile for reducing the space occupied by the wiring harness in the Z direction.

[0006] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0007] Firstly, the wire harness fixing device provided in this application includes a housing structure and a connecting structure. The housing structure includes at least two slots that extend along a first direction and are configured to accommodate a portion of the cable in the wire harness. The connecting structure is connected to the housing structure and is configured to fix the position of the wire harness fixing device.

[0008] The wire harness fixing device provided in this application includes a receiving structure for storing a wire harness, which comprises a combination of multiple cables, thus the diameter of the wire harness is larger than the diameter of the cables. Since the receiving structure includes at least two slots, and these slots are configured to hold portions of the cables within the wire harness, the wire harness is distributed into different slots when stored in the receiving structure, with each slot holding a portion of the wire harness. Because each slot holds a portion of the wire harness, the diameter of the portion of the cable in each slot is smaller than the diameter of the wire harness. Therefore, the space occupied by the wire harness in the Z-direction using the wire harness fixing device provided in this application is smaller than the space occupied by the entire wire harness in the Z-direction. The slots extending along a first direction mean that the cables can extend uniformly along the first direction, which helps improve the orderly management of the cables. A connecting structure is connected to the receiving structure and configured to fix the position of the wire harness fixing device, making the entire wire harness fixing device more stable and reliable.

[0009] As one possible implementation, at least two slots have equal widths, the width of which is the dimension of the slot in a second direction, which is perpendicular to the first direction.

[0010] As one possible implementation, the storage structure includes a support bracket and at least one partition plate. The support bracket includes a base plate, a first side wall, and a second side wall. The first side wall is connected to the base plate, and the second side wall is also connected to the base plate. The base plate of the support bracket is connected to a connecting structure. At least one partition plate is disposed between the first and second side walls and connected to the base plate. The at least one partition plate, the first side wall, and the second side wall are located on the same side of the base plate. The at least one partition plate divides the support bracket into at least two slots.

[0011] As one possible implementation, each slot is provided with at least one set of cable tie holes, each set including two cable tie holes that penetrate the base plate, and the set of cable tie holes is configured to accommodate cable ties passing through to secure cables located in the slot.

[0012] As one possible implementation, the storage structure includes a wire harness inlet and a wire harness outlet, and the base plate corresponding to each slot is provided with a group of cable tie holes near the wire harness inlet and outlet.

[0013] As one possible implementation, the connection structure includes a first connector and a second connector. The first connector is connected to the base plate of the support bracket, and the second connector is connected to the base plate of the support bracket, with a gap between the first connector and the second connector.

[0014] As one possible implementation, the storage structure includes a support bracket made of PA66 engineering plastic.

[0015] Secondly, this application provides an automobile, which includes sheet metal and a wiring harness fixing device as mentioned in the first aspect and its possible implementations, wherein the connection structure of the wiring harness fixing device is connected to the sheet metal.

[0016] As one possible implementation, the connection structure includes a snap-fit ​​and a limiting post, and the sheet metal includes a snap-fit ​​mating part that matches the snap-fit ​​and a limiting hole corresponding to the limiting post. The beneficial effects of the second aspect and its possible implementations can be referred to the beneficial effects of the first aspect, and will not be elaborated here.

Detailed Implementation

[0024] The embodiments of this application will be described below with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of this application from the content disclosed in this specification. This application can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this application. It should be understood that the preferred embodiments are only for illustrating this application and are not intended to limit the scope of protection of this application.

[0025] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of this application. Therefore, the drawings only show the components related to this application and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0026] In the description of the embodiments, unless otherwise stated, " / " means "or". For example, A / B can mean A or B. The "and / or" in this document is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, and B alone. Furthermore, "at least one" and "more than one" refer to two or more. The terms "first," "second," etc., do not limit the quantity or execution order, and "first," "second," etc., do not necessarily imply that they are different.

[0027] As a widely used means of transportation, a car's height is generally less than its length. Since the height of a car largely determines the space for the driver and passengers in the Z-direction, and the length largely determines the space for the driver and passengers in the X-direction (i.e., the space for the passenger or driver to move forward and backward in the car, where the X-direction is horizontal, for example), the space for the driver and passengers to move in the Z-direction (i.e., the space for the passenger or driver to move up and down in the car, where the Z-direction is vertical, for example) is far less than the space for the driver and passengers to move in the X-direction.

[0028] With the continuous development of automotive intelligence, there are more and more controllers in the vehicle, resulting in increasingly complex wiring harnesses and thicker wires. The wire diameter, or the diameter of the wiring harness, means that the harness will occupy more and more space in the Z-direction. This further compresses the space available for the driver and passengers to move in the Z-direction, significantly impacting the user experience.

[0029] In view of this, this application provides a wire harness fixing device, exemplarily, such as... Figure 1 As shown. The wire harness fixing device includes a housing structure 1 and a connecting structure 2. The housing structure 1 includes at least two slots 11 that extend along a first direction (X direction) and are configured to hold a portion of the cable in the wire harness. The connecting structure 2 is connected to the housing structure 1 and is configured to fix the position of the wire harness fixing device.

[0030] The wire harness fixing device provided in this application includes a housing structure 1 for housing a wire harness, which comprises a combination of multiple cables, and therefore the diameter of the wire harness is larger than the diameter of the cables. Since the housing structure 1 includes at least two slots 11, ( Figure 1 (Illustrated with three slots 11) These slots 11 are configured to hold portions of the cables in the wiring harness. Therefore, when the wiring harness is stored in the storage structure, it is distributed into different slots 11, with each slot 11 holding a portion of the wiring harness. By distributing the wiring harness to different slots 11 in the storage structure 1, each slot 11 only holds a portion of the cable assembly, making the diameter of the cable assembly in each slot 11 smaller than the diameter of the entire wiring harness. This design effectively reduces the height of the wiring harness in the Z-direction, thereby relatively increasing the space for passenger and driver movement in the Z-direction.

[0031] Furthermore, the split cables are arranged in different slots 11, making the stress distribution on the cables in each slot 11 more uniform, improving the overall stability and reliability of the fixation, and reducing the risk of damage to the cables due to stress concentration. The slots 11 run through the first direction (X direction), allowing the cables to be neatly arranged and laid out along this direction. This not only makes the cable routing more orderly, but also facilitates subsequent maintenance, inspection, and replacement. The neatly arranged cables help reduce tangling and mess, thereby improving management efficiency. Through the combination of the connecting structure 2 and the storage structure 1, the fixing device can more securely fix the cable bundle.

[0032] It should be understood that the more slots 11 are set, the more wire harnesses are split, and the fewer cables each slot 11 can hold, resulting in a smaller diameter of the cable combination in each slot 11, thereby further improving the activity space for passengers and drivers in the Z direction.

[0033] It should also be understood that this application does not specify the width of the slot 11 (i.e., the width of the slot in...). Figure 1 The distance in the Y direction shown is limited, and the different widths of the slot 11 can accommodate cable combinations of different diameters, improving the versatility of the fixing device. For example, whether it is a thinner signal line or a thicker power line, it can be effectively stored and fixed through this design, thereby meeting the needs of different application scenarios.

[0034] As one possible implementation, such as Figure 1As shown, at least two slots 11 have equal widths. The width of a slot 11 is its dimension in the second direction (Y direction), which is perpendicular to the first direction (X direction). When the slots 11 have equal widths, the cables are more evenly distributed within each slot 11. This ensures that the cable combinations within each slot 11 are approximately the same size, resulting in a more balanced stress distribution throughout the entire storage structure 1, thereby reducing the risk of wear or damage due to excessive local stress. Furthermore, the equal width of the slots 11 simplifies the design and manufacturing process of the storage structure. There is no need to consider slots 11 of different widths individually during design, and standardized processing equipment and processes can be used during manufacturing, improving production efficiency and reducing manufacturing costs.

[0035] As one possible implementation, such as Figure 2 As shown, the storage structure 1 includes a support bracket 12 and at least one partition plate 13. The support bracket 12 includes a base plate 121, a first side wall 122, and a second side wall 123. The first side wall 122 is connected to the base plate 121, and the second side wall 123 is also connected to the base plate 121. The base plate 121 of the support bracket 12 is connected to the connecting structure 2. At least one partition plate 13 is disposed between the first side wall 122 and the second side wall 123 and is connected to the base plate 121. The at least one partition plate 13, the first side wall 122, and the second side wall 123 are located on the same side of the base plate 121. The at least one partition plate 13 divides the support bracket 12 into at least two slots 11.

[0036] When there is only one partition plate 13, the partition plate 13, the first side wall 122, and a portion of the bottom plate 121 located between the partition plate 13 and the first side wall 122 form a slot 11, and the partition plate 13, the second side wall 123, and a portion of the bottom plate 121 located between the partition plate 13 and the second side wall 123 form another slot 11. That is, one partition plate 13 divides the support bracket 12 into two slots 11.

[0037] In the case where the storage structure 1 includes multiple partitions 13, the multiple partitions 13 are disposed between the first side wall 122 and the second side wall 123. One partition 13 forms a slot 11 with the first side wall 122 and a portion of the base plate 121 connected to the partition 13 and the first side wall 122. Another partition 13 forms a slot 11 with the second side wall 122 and a portion of the base plate 121 connected to the partition 13 and the second side wall 123. A slot 11 is formed between adjacent partitions 13 and a portion of the base plate 121 connected to the adjacent partition 13. Each slot 11 corresponds to a portion of the base plate 121. That is, the multiple partitions 13 divide the support bracket 12 into at least three slots 11.

[0038] The storage structure 1 provided in this embodiment includes a support bracket 12 and a partition plate 13. The support bracket 12 includes a base plate 121, a first side wall 122, and a second side wall 123. Both the first side wall 122 and the second side wall 123 are connected to the base plate 121 to form a stable support structure. The base plate 121 of the support bracket 12 is connected to the connecting structure 2, thereby fixing the storage structure 1 in a predetermined position.

[0039] In this embodiment, the partition plate 13 is disposed between the first sidewall 122 and the second sidewall 123. To achieve orderly management of the wire harness, multiple partition plates 13 are disposed within the support bracket 12. As one possible implementation, these partition plates 13 are arranged at equal intervals between the first sidewall 122 and the second sidewall 123. Through this design, multiple slots 11 are formed between the partition plate 13 and a portion of the base plate 121, the first sidewall 122, or the second sidewall 123, with each slot 11 corresponding to a portion of the base plate 121.

[0040] The evenly spaced spacing of the spacers 13 ensures that each slot 11 has the same width, allowing each cable section to be neatly and evenly arranged within each slot 11. The structural design of the slots 11 facilitates cable routing and arrangement, significantly reducing the height of the cable bundle in the Z-direction. Furthermore, the robust connection between the support bracket 12 and the connecting structure 2 enhances the stability of the entire storage structure 1, thereby ensuring the safety and secure fixation of the cables.

[0041] In some embodiments, such as Figure 3 As shown, each slot 11 is provided with at least one set of cable tie hole groups 110. Each set of cable tie hole groups 110 includes two cable tie holes 111 penetrating the base plate. The cable tie holes 111 are configured to accommodate cable ties passing through to secure cables located in the slot 11. As one possible implementation, the cable tie hole groups 110 are positioned in the middle of the slot 11. Cable ties passing through the cable tie holes 111 secure the cables inside the slot 11. Positioning the cable tie hole groups 110 in the middle of the slot 11 ensures that the cables are fixed at the center of the slot 11, resulting in more even force distribution and reducing the risk of loosening or displacement of the cables during external vibration or movement. This further improves the overall structural stability of the wire harness securing device.

[0042] In other embodiments, such as Figure 4As shown, the storage structure 1 includes a wire harness inlet 14 and a wire harness outlet 15. Each slot 11 has a base plate with cable tie hole groups 110 located near the wire harness inlet 14 and outlet 15. The cable tie hole groups 110 at the wire harness inlet 14 and outlet 15 of each slot 11 allow cable ties to pass through, enabling more cable ties to bind the wire harness within the slot 11. This effectively prevents the cables from sliding inside the slot 11, especially in vertical or inclined installation environments, ensuring the orderly arrangement of cables within the slot 11. Therefore, it further enhances the overall structural stability of the wire harness fixing device.

[0043] In some embodiments, such as Figure 5 As shown, the connection structure 2 includes a first connector 21 and a second connector 22. The first connector 21 is connected to the base plate 121 of the support bracket 12, and the second connector 22 is also connected to the base plate 121 of the support bracket 12. There is a gap L1 between the first connector 21 and the second connector 22. The first connector 21 can fix the position of the wire harness fixing device, and the second connector 22 can also fix the position of the wire harness fixing device. When the first connector 21 and the second connector 22 are used together, the position of the wire harness fixing device can be stabilized, preventing the wire harness fixing device from falling off due to external vibration, and further improving the overall structural stability of the wire harness fixing device.

[0044] As one possible implementation, the first connector is a snap-fit, and the second connector is a locking post. A snap-fit, also known as a hook, latch, or latch, is a common connecting and fixing structure used in product structures. The locking post is typically used in conjunction with the snap-fit; one end of the locking post usually engages in a locking hole located on the fixing object of the wire harness fixing device. The size of the locking hole is just right to accommodate the locking post, thus preventing the locking post from changing position, i.e., preventing the locking post from slipping due to external vibration. Since one end of the locking post is connected to the base plate of the support bracket, when the locking post is locked by the locking hole, the support bracket is also locked, thus improving the stability of the wire harness fixing device.

[0045] One possible implementation is a storage structure that includes a support bracket made of PA66 engineering plastic. PA66, also known as polyamide 66, is a widely used engineering thermoplastic. It belongs to the polyamide or nylon polymer family and is synthesized from hexamethylenediamine and adipic acid. It possesses advantages such as high mechanical strength, high temperature resistance, chemical resistance, and high wear resistance. Therefore, a support bracket made of PA66 engineering plastic can have a longer lifespan and be more reliable.

[0046] This application also provides an automobile, which includes sheet metal and a wiring harness fixing device as described above, exemplarily, such as... Figure 6As shown. The connecting structure 2 of the wire harness fixing device is connected to the sheet metal. The wire harness fixing device provided in this application includes a receiving structure 1 for receiving a wire harness, which comprises a combination of multiple cables, and therefore the diameter of the wire harness is larger than the diameter of the cables. Since the receiving structure 1 includes at least two slots, and the slots are configured to hold portions of the cables in the wire harness, the wire harness is diverted into different slots when it is received in the receiving structure, with each slot containing a portion of the wire harness. Since each slot contains a portion of the wire harness, the diameter of the cable combination in each slot is smaller than the diameter of the wire harness. The slots extending along a first direction mean that the cables can be arranged along the first direction, which helps to improve the orderly management of the cables.

[0047] The connecting structure 2 is connected to the storage structure 1 and is configured to fix the position of the wire harness fixing device. The wire harness of the in-vehicle controller is fixed to the sheet metal 3 through the wire harness fixing device. Since each slot only stores a part of the cable combination, the diameter of the cable combination in each slot is smaller than the diameter of the entire wire harness. Therefore, the height of the wire harness in the Z direction can be effectively reduced, thereby relatively increasing the activity space of passengers and drivers in the Z direction.

[0048] One possible implementation involves a connection structure including a snap-fit ​​and a limiting post. The sheet metal includes a snap-fit ​​mating part that matches the snap-fit ​​and a limiting hole corresponding to the limiting post. The snap-fit ​​and snap-fit ​​mating part cooperate to fix the position of the storage structure on the sheet metal. The limiting post is inserted into the limiting hole, and since the size of the limiting hole is just right to accommodate the limiting post, it can prevent the position of the limiting post from changing, that is, prevent the limiting post from slipping due to external vibration. Since one end of the limiting post is connected to the base plate of the support bracket, when the limiting post is limited by the limiting hole, the support bracket is also limited, thus improving the stability of the wire harness fixing device.

[0049] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any changes or substitutions within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
