Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of wire harness fixing, and more specifically, to a wire harness fixing device and a vehicle. Background Art

[0002] Wire harnesses play a crucial role in modern electronic devices, automation systems, and various complex mechanical devices, responsible for signal transmission and power distribution. With the progress of technology, wire harness design tends to be of higher density and more complex layout. However, the width of wire harnesses often varies according to specific electrical requirements. In traditional wire harness fixing technologies, wire harness fixing devices are usually of fixed size. When facing wire harnesses with variable widths, the wire harness fixing devices cannot be adapted, and it is necessary to redesign wire harness fixing devices corresponding to the widths, resulting in increased wire harness fixing costs and reduced fixing efficiency.

[0003] In view of the above technical problems, no effective solution has been proposed yet. Summary of the Invention

[0004] The embodiments of the present application provide a wire harness fixing device and a vehicle, aiming to improve the problem that the existing wire harness fixing device cannot adapt to the change in the width of the wire harness.

[0005] According to one aspect of the embodiments of the present application, a wire harness fixing device is provided, including: a fixing mechanism, the fixing mechanism includes a fixing base and a first mounting component disposed on the fixing base; an adjusting mechanism, the adjusting mechanism at least includes a second mounting component, the second mounting component is disposed at a distance from the first mounting component, so as to form a limiting space between the second mounting component and the first mounting component, and the limiting space is used for accommodating the wire harness; wherein, the distance between the second mounting component and the first mounting component is set to be adjustable, so as to adjust the width of the limiting space.

[0006] The above embodiments of the present application can achieve the following beneficial effects: By setting an adjustable distance between the second mounting component and the first mounting component, the width of the limiting space can be adjusted, so that the wire harness fixing device can flexibly adapt to wire harnesses of different widths, effectively solving the problem in the prior art that the fixing device cannot adapt to the change in the width of the wire harness. When using the wire harness fixing device in this embodiment to fix the wire harness, one wire harness fixing device can meet the fixing requirements of wire harnesses of multiple widths, eliminating the need to customize dedicated fixing parts for each type of wire harness, reducing the demand for multiple specifications of fixing parts, simplifying material management and inventory control, avoiding additional expenses caused by frequent replacement of the fixing device, and helping to reduce the overall production and maintenance costs; The adjustable width of the limiting space ensures that the wire harness can be accurately positioned during the fixing process, effectively reducing the wire harness position offset, improving the consistency and stability of the assembly, and thus enhancing the reliability of the wire harness system; During the assembly process, the adjustable wire harness fixing device significantly shortens the time required to adjust the fixing structure due to the change in the width of the wire harness, improves the efficiency of wire harness assembly, speeds up the production cycle of the product, and at the same time reduces the operation complexity of workers.

[0007] Further, the adjusting mechanism further includes an adjusting base, the second mounting component is connected to the adjusting base, the adjusting base is connected to the fixed base, and the adjusting base and the fixed base are arranged to be relatively movable to adjust the width of the limiting space.

[0008] The above optional embodiments of the present application can achieve the following beneficial effects: By adjusting the distance between the second mounting component and the first mounting component through the adjusting base, a smoother and more precise adjustment operation can be provided. By designing the adjustment mechanism of the adjusting base, such as a rack, gear or slide rail system, the adjustment process can be made more controllable and accurate, avoiding the errors and inconveniences that may occur when directly manually adjusting the distance between the two components. Moreover, the adjusting base can be used to support the second mounting component, and operating the adjusting base alone can drive the second mounting component to move, avoiding damage to the second mounting component caused by directly operating the second mounting component to move.

[0009] Further, at least one of the fixing mechanism and the adjusting mechanism is further provided with a mounting mechanism, and the wire harness fixing device is connected to the mounting base through the mounting mechanism.

[0010] The above optional embodiments of the present application can achieve the following beneficial effects: Through the mounting mechanism, the wire harness fixing device can be quickly installed on different mounting bases without modifying the wire harness fixing device itself, enhancing the application range and adaptability of the wire harness fixing device; Moreover, the use of the mounting mechanism enables the wire harness fixing device to be relatively easily removed from the mounting base, facilitating the repair, inspection and replacement of the wire harness, reducing the impact on other parts of the vehicle, and improving the maintenance efficiency.

[0011] Further, the wire harness fixing device further includes: a locking mechanism, which has a locking state for locking the adjustment base and the fixed base, and a releasing state for releasing the locking between the adjustment base and the fixed base; when the locking mechanism is in the locking state, the adjustment base and the fixed base are fixedly arranged relative to each other, and when the locking mechanism is in the releasing state, the adjustment base and the fixed base are arranged to be relatively movable.

[0012] The above optional embodiments of the present application can achieve the following beneficial effects: in the locking state, the locking mechanism fixedly connects the adjustment base and the fixed base to form a stable whole, and the adjustment base cannot move relative to the fixed base, effectively preventing the accidental separation of the adjustment base and the fixed base, ensuring the long-term stable fixation of the wire harness, and avoiding circuit failures or safety hazards; in the releasing state, the locking mechanism releases the locking between the adjustment base and the fixed base, allowing the adjustment base to move relative to the fixed base, so as to adjust the distance between the two according to the actual width of the wire harness and achieve the best fixing effect. When it is necessary to replace the wire harness or perform maintenance, unlocking the locking mechanism can easily move the adjustment base without completely disassembling the entire wire harness fixing device, simplifying the maintenance work and reducing the operation difficulty.

[0013] Further, the fixed base has a through accommodation space, a part of the adjustment base is located on the first side of the accommodation space and is connected to the second mounting assembly, and another part of the adjustment base passes through the accommodation space and extends to the second side of the accommodation space, wherein the adjustment base is arranged to be relatively movable with respect to the fixed base to adjust the length of the adjustment base extending to the second side of the accommodation space, thereby adjusting the width of the limiting space.

[0014] The above optional embodiments of the present application can achieve the following beneficial effects: the adjustment base can slide freely in the accommodation space to adjust the length extending to the other side of the accommodation space as needed. The extending length of the adjustment base directly determines the width of the limiting space, that is, the width of the wire harness clamped by the wire harness fixing device.

[0015] Further, a fitting is arranged in the accommodation space. The fitting is provided with a first fitting structure, and the adjustment base is provided with a second fitting structure that cooperates with the first fitting structure. When the locking mechanism is in the releasing state, the fitting is in a movable state, and the relative movement of the adjustment base with respect to the fixed base can drive the fitting to move along a preset direction. When the locking mechanism is in the locking state, the fitting is in a fixed state to limit the relative movement of the adjustment base with respect to the fixed base.

[0016] The above optional embodiments of the present application can achieve the following beneficial effects: The fitting is matched with the first fitting structure of the adjusting base through the second fitting structure, so that the fitting moves along with the adjusting base when the adjusting base moves. When the locking mechanism locks the fitting and the fitting cannot move, the movement of the adjusting base is also locked, that is, the position of the adjusting base is fixed. Through the cooperation of the second fitting structure and the first fitting structure, the movement of the adjusting base is ensured to be stable and the adjustment process is accurate, reducing the structural stress and wear that may be brought about by the direct connection of the adjusting base with the locking mechanism and the fixed base, thereby extending the service life of the device and improving the reliability of wire harness fixing.

[0017] Further, the fitting is provided with at least one first fitting structure, and the adjusting base is provided with a plurality of second fitting structures arranged at intervals. During the movement of the adjusting base relative to the fixed base, adjacent two first fitting structures are sequentially matched with the second fitting structures to enable the fitting to move along a preset direction.

[0018] The above optional embodiments of the present application can achieve the following beneficial effects: The plurality of second fitting structures are distributed at intervals along the moving direction of the adjusting base, forming a dynamic interaction with the first fitting structure, ensuring that the fitting can move smoothly and accurately in the preset direction.

[0019] Further, the fitting includes an elastic piece, the elastic piece is connected to the side wall of the accommodating space, and the first fitting structure is arranged on the elastic piece. When the elastic piece is in a movable state, during the movement of the adjusting base relative to the fixed base, part of the elastic piece moves along the height direction of the fixed base, so that adjacent two second fitting structures are sequentially matched with the first fitting structure.

[0020] The above optional embodiments of the present application can achieve the following beneficial effects: Through the elastic characteristics of the elastic piece, during the movement of the adjusting base, the elastic piece undergoes corresponding deformation and recovery, so as to achieve precise cooperation with the second fitting structure. When it is necessary to fix the position of the adjusting base, it is only necessary to restrict the movement of the elastic piece in the height direction.

[0021] Further, one of the first fitting structure and the second fitting structure is a fitting groove, and the other of the first fitting structure and the second fitting structure is a fitting protrusion.

[0022] The above optional embodiments of the present application can achieve the following beneficial effects: By setting the structure of the fitting groove and the fitting protrusion, the first fitting structure and the second fitting structure are mutually embedded fitting structures. After adjusting the width of the limiting space, the position stability of the adjusting base can be ensured through the embedded structure, avoiding the position deviation of the adjusting base caused by the shaking of the device.

[0023] Further, the first fitting structure and the second fitting structure are tooth structures that mesh with each other.

[0024] The above-mentioned optional embodiments of the present application can achieve the following beneficial effects: by setting the first matching structure and the second matching structure to a meshing matching mode, the connection stability between the adjustment base and the fixed base can be enhanced, and after the position adjustment of the adjustment base is completed, the position displacement of the adjustment base due to shaking can be avoided.

[0025] Furthermore, the tooth structure is protrudingly arranged along the height direction of the fixed base, and the tooth structure has two end surfaces arranged opposite to each other, one of which is an inclined surface, and the other end surface is a straight surface extending along the height direction of the fixed base.

[0026] The above optional embodiments of the present application can achieve the following beneficial effects: the inclined surface of the tooth structure can play a guiding role in the movement of the adjustment base. When the adjustment base starts to move, the inclined surface can help the second matching structure on the adjustment base to smoothly guide into the first matching structure. Even in the case of a slight alignment deviation, the inclined surface can use its guiding characteristics to make the adjustment base move smoothly along the predetermined path, reducing the jamming phenomenon during operation; the straight surface of the tooth structure plays a positioning and locking role. When the adjustment base moves to a certain preset position, the straight surface forms a close contact with the second matching structure. Since the straight surface has a high verticality, it can effectively limit the further movement of the adjustment base and ensure the stability of the adjustment base at this position. Through the cooperation of the inclined surface and the straight surface, the smooth movement and precise positioning of the adjustment base on the fixed base can be achieved, the adjustment accuracy and stability of the wire harness fixing device can be improved, and the accidental movement of the adjustment mechanism during use can be prevented.

[0027] Furthermore, the locking mechanism includes a locking tongue. When the locking mechanism is in a locked state, at least part of the locking tongue is located in the accommodating space. In the height direction of the fixed base, at least part of the locking tongue is located on the side of the spring sheet away from the second matching structure and abuts against the spring sheet.

[0028] The above-mentioned optional embodiments of the present application can achieve the following beneficial effects: the abutment between the locking tongue and the spring sheet prevents the spring sheet from being deformed due to external force, that is, it prevents the spring sheet from moving in the height direction, thereby limiting any movement of the adjustment base within the fixed base, ensuring the stable fixation of the adjustment mechanism, and enhancing the mechanical stability of the entire device.

[0029] Furthermore, the locking mechanism includes a locking and fixing structure, the locking and fixing structure is connected to the locking tongue piece, and the locking tongue piece is detachably connected to the fixed base through the locking and fixing structure.

[0030] The above optional embodiments of the present application can achieve the following beneficial effects: The detachable connection design can improve the flexibility and maintenance convenience of the locking mechanism. When the locking tongue or the locking fixing structure is damaged or needs to be replaced, the damaged parts can be easily disassembled for repair or replacement without replacing the entire fixing mechanism, reducing the maintenance cost and time.

[0031] Further, the first mounting assembly includes a first mounting plate and a first limiting member disposed on the first mounting plate, and a limiting space is formed between the second mounting assembly and the first limiting member.

[0032] The above optional embodiments of the present application can achieve the following beneficial effects: The first mounting plate can be used to carry the wire harness, and the first limiting member can be used to cooperate with the second mounting assembly to form a limiting space. By adjusting the distance between the second mounting assembly and the first limiting member, the width of the limiting space can be adjusted to adapt to wire harnesses of different widths. The first limiting member limits and fixes the wire harness in the width direction of the wire harness, effectively preventing the wire harness from shaking and falling off.

[0033] Further, the second mounting assembly includes a second mounting plate and a second limiting member disposed on the second mounting plate, and a limiting space is formed between the second limiting member and the first limiting member.

[0034] The above optional embodiments of the present application can achieve the following beneficial effects: The second mounting plate can be used to carry the wire harness, and the second limiting member can be used to cooperate with the first limiting member to form a limiting space. By adjusting the distance between the second limiting member and the first limiting member, the width of the limiting space can be adjusted to adapt to wire harnesses of different widths. The second limiting member and the first limiting member are respectively located on both sides in the width direction of the wire harness, which can effectively prevent the wire harness from shaking and falling off.

[0035] Further, the second mounting assembly includes a limiting body, the limiting body is connected to the first mounting plate, and a limiting space is formed between the limiting body and the first limiting member.

[0036] The above optional embodiments of the present application can achieve the following beneficial effects: By directly providing a limiting body connected to the first mounting plate, such that the limiting body and the first limiting member form a limiting space, the structure of the second mounting assembly can be simplified. By only adjusting the connection position between the limiting body and the first mounting plate, the width of the limiting space can be adjusted, effectively reducing the structural complexity and manufacturing cost.

[0037] Further, a plurality of first connection parts are provided on the first mounting plate, the plurality of first connection parts are arranged at intervals, and a second connection part matching the first connection part is provided on the limiting body. The second connection part can be selectively matched with any one of the first connection parts to adjust the distance between the limiting body and the first limiting member.

[0038] The above optional embodiments of the present application can achieve the following beneficial effects: The multiple first connection parts provided on the first mounting plate can provide multiple connection points for the limiting body. By selectively cooperating the second connection part with the first connection part at any position, the limiting body can be fixed at different positions on the first mounting plate, thereby adjusting the distance between the limiting body and the first limiting part, and further realizing the adjustment of the width of the limiting space.

[0039] Further, the mounting mechanism includes: a mounting body, the mounting body is connected to the fixed base, the mounting body includes a first stop section close to the fixed base and a second stop section far from the fixed base, and the radial dimension of the first stop section is set to be larger than that of the second stop section; wherein, an elastic stop structure is provided on the outer peripheral surface of the second stop section, the elastic stop structure is telescopically arranged along the radial direction of the second stop section, and a clamping space is formed between the elastic stop structure and the first stop section, and the clamping space is used for clamping at least part of the mounting base.

[0040] The above optional embodiments of the present application can achieve the following beneficial effects: The second stop section with a smaller radial dimension can be used to penetrate through the mounting base, and the first stop section with a larger radial dimension can form a stop surface to prevent the mounting base from coming out. The elastic stop structure can be telescopically arranged in the radial direction. During the installation process, the elastic stop structure can contract when pressed, facilitating the insertion of the mounting base; after the mounting base is in place, the elastic stop structure returns to its original state to form an effective stop to ensure that the mounting base will not come out of the clamping space. The setting of the elastic stop structure can facilitate the connection between the mounting mechanism and mounting bases with different radial sizes, effectively improving the practicability of the device.

[0041] Further, the elastic stop structure includes a plurality of stop protrusions, the plurality of stop protrusions are sequentially arranged along the axial direction of the second stop section, and, along the direction away from the fixed base, the dimensions of the plurality of stop protrusions in the radial direction of the second stop section gradually increase, so that adjacent two stop protrusions form a stop step facing the fixed base.

[0042] The above optional embodiments of the present application can achieve the following beneficial effects: Through the plurality of stop steps sequentially arranged along the axial direction of the second stop section, clamping spaces with different axial lengths can be formed between the stop steps at different positions and the second stop section. The clamping spaces with different axial lengths can be adapted to mounting bases with different thicknesses, improving the practicability of the wire harness fixing device; the stop steps can not only play a physical stop role, but also form multiple contact points between the mounting base and the mounting mechanism, enhancing the stability and tightness of the clamping.

It should be understood that such terms can be interchanged under appropriate circumstances so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein.

[0075] Now, exemplary embodiments according to the present application will be described in more detail with reference to the drawings. However, these exemplary embodiments can be implemented in many different forms and should not be construed as being limited only to the embodiments set forth herein. It should be understood that these embodiments are provided so that the disclosure of the present application is thorough and complete, and the concept of these exemplary embodiments is fully conveyed to those of ordinary skill in the art. In the drawings, for clarity, the thickness of layers and regions may be exaggerated, and the same reference numerals are used to denote the same devices, and thus their description will be omitted.

[0076] In the existing vehicle wiring harness technology, the application of flat flexible cables (FFCs) is becoming increasingly widespread. Due to its thin, light, and flexible characteristics and ease of wiring, the FFC has replaced traditional cables in many fields and has become the first choice in wiring harness design. The width of the FFC often varies according to specific electrical requirements. In traditional wiring harness fixing technologies, the fixing devices are usually of a fixed size and are optimized for wiring harnesses of a specific width during design. When facing an FFC with a variable width, this fixing method has the following defects:

[0077] Adaptability limitation: Once the width of the wire harness changes, the fixing device either cannot adapt or needs to be redesigned, resulting in increased costs and reduced efficiency.

[0078] Assembly consistency problem: Due to the lack of an accurate limiting structure, it is difficult to precisely control the position of the wire harness when installing FFCs of different widths. The human factors in the assembly process have a significant impact, resulting in poor consistency.

[0079] Complex material management: To meet the installation requirements of FFCs with different widths, it is necessary to prepare fixing devices of various specifications. This not only increases the types of materials but also brings additional complexity to production management and inventory control.

[0080] Inconvenient adjustment: Every time the width of the FFC wire harness changes, the adjustment process of the fixing device is cumbersome and time-consuming, reducing the flexibility of the assembly line and the overall production efficiency.

[0081] Combined Figures 1 to 18 As shown, according to a specific embodiment of the present application, a wire harness fixing device is provided.

[0082] A wire harness fixing device provided by an embodiment of the present application includes a fixing mechanism 10 and an adjusting mechanism 20. The fixing mechanism 10 includes a fixing base 110 and a first mounting component 120 disposed on the fixing base 110; the adjusting mechanism 20 at least includes a second mounting component 220, and the second mounting component 220 is disposed at a distance from the first mounting component 120 so as to form a limiting space 300 between the second mounting component 220 and the first mounting component 120. The limiting space 300 is used to accommodate the wire harness 3; wherein, the distance between the second mounting component 220 and the first mounting component 120 is set to be adjustable to adjust the width of the limiting space 300.

[0083] The above embodiments of the present application can achieve the following beneficial effects: By setting an adjustable distance between the second mounting component 220 and the first mounting component 120, the width of the limiting space 300 can be adjusted, so that the wire harness fixing device can flexibly adapt to wire harnesses of different widths, effectively solving the problem in the prior art that the fixing device cannot adapt to the change in the width of the wire harness. When using the wire harness fixing device in this embodiment to fix the wire harness, one wire harness fixing device can meet the fixing requirements of wire harnesses of multiple widths, eliminating the need to customize dedicated fixing parts for each type of wire harness, reducing the demand for fixing parts of multiple specifications, simplifying material management and inventory control, avoiding additional expenses caused by frequent replacement of the fixing device, and helping to reduce the overall production and maintenance costs; The adjustable width of the limiting space 300 ensures that the wire harness can be accurately positioned during the fixing process, effectively reducing the displacement of the wire harness position, improving the consistency and stability of the assembly, and thus enhancing the reliability of the wire harness system; During the assembly process, the adjustable wire harness fixing device significantly shortens the time required to adjust the fixing structure due to the change in the width of the wire harness, improves the efficiency of wire harness assembly, accelerates the production cycle of the product, and at the same time reduces the operation complexity of workers.

[0084] It should be noted that this embodiment can be applied to vehicles, ships, aircraft, airplanes, industrial machinery, household appliances, laboratory equipment, and other precision machinery, and is applicable to various mechanical and electrical equipment with wire harness fixing requirements.

[0085] Furthermore, the adjusting mechanism 20 further includes an adjusting base 210. The second mounting component 220 is connected to the adjusting base 210, and the adjusting base 210 is connected to the fixed base 110. Moreover, the adjusting base 210 and the fixed base 110 are arranged to be relatively movable to adjust the width of the limiting space 300.

[0086] The above optional embodiments of the present application can achieve the following beneficial effects: By adjusting the distance between the second mounting component 220 and the first mounting component 120 through the adjusting base 210, a smoother and more precise adjustment operation can be provided. By designing the adjustment mechanism of the adjusting base, such as a rack, gear, or slide rail system, the adjustment process can be made more controllable and accurate, avoiding errors and inconveniences that may occur when directly manually adjusting the distance between the two components. Additionally, the adjusting base 210 can be used to support the second mounting component 220, and operating the adjusting base 210 alone can drive the movement of the second mounting component 220, avoiding damage to the second mounting component 220 caused by directly operating the movement of the second mounting component 220.

[0087] In an alternative embodiment of the present application, the adjustment base 210 is detachably connected to the second mounting assembly 220. The detachable connection design enables the connection between the adjustment base 210 and the second mounting assembly 220 to be disassembled relatively easily, allowing the user or assembler to adjust or replace the second mounting assembly 220 and the adjustment base 210 as needed. It provides the ability to quickly adjust the adjustment mechanism 20, while offering convenience during maintenance or replacement, reducing the assembly time and improving work efficiency. Specifically, the detachable connection method can include various methods such as bolt-nut connection, snap connection, magnetic attraction connection, etc.

[0088] In another alternative embodiment of the present application, the adjustment base 210 is fixedly connected to the second mounting assembly 220. The fixed connection method can resist vibration and shock and maintain the stability of the device. Specifically, the fixed connection can be achieved through various methods such as welding, bonding, riveting, integral molding, etc.

[0089] Furthermore, at least one of the fixing mechanism 10 and the adjustment mechanism 20 is further provided with a mounting mechanism 40, and the wire harness fixing device is connected to the mounting base 50 through the mounting mechanism 40.

[0090] The above alternative embodiments of the present application can achieve the following beneficial effects: Through the mounting mechanism 40, the wire harness fixing device can be quickly installed on different mounting bases 50, such as different parts of the vehicle body, inside the cab, or in the engine compartment, without modifying the wire harness fixing device itself, enhancing the application range and adaptability of the wire harness fixing device; and the use of the mounting mechanism 40 enables the wire harness fixing device to be relatively easily removed from the mounting base 50, facilitating the maintenance, inspection, and replacement of the wire harness 3, reducing the impact on other parts of the vehicle, and improving the maintenance efficiency.

[0091] It should be noted that the mounting mechanism 40 can be provided only on the fixing mechanism 10, or only on the adjustment mechanism 20, or can be provided on both the fixing mechanism 10 and the adjustment mechanism 20 at the same time. Specifically, the mounting mechanism 40 can be structurally designed according to the actual application scenario. For example, the mounting mechanism 40 can be a magnetic attraction structure, or the mounting mechanism 40 can be a quick-release latch structure.

[0092] Preferably, as Figure 18 shown, a plurality of mounting holes 501 are formed on the mounting base 50, and the cross-sectional shapes and hole diameters of the respective mounting holes 501 can be set differently. For example, the mounting holes 501 can be various shapes such as waist-shaped holes, circular holes, strip-shaped holes, etc. And, taking the mounting holes 501 all being waist-shaped holes as an example, the length directions of the respective waist-shaped holes can be set differently. The mounting mechanism 40 is connected to the mounting base 50 through the mounting holes 501.

[0093] Furthermore, the wire harness fixing device further includes a locking mechanism 60. The locking mechanism 60 has a locking state in which the adjusting base 210 and the fixing base 110 are locked, and the locking mechanism 60 has a releasing state in which the adjusting base 210 and the fixing base 110 are released. When the locking mechanism 60 is in the locking state, the adjusting base 210 and the fixing base 110 are fixedly arranged relative to each other. When the locking mechanism 60 is in the releasing state, the adjusting base 210 and the fixing base 110 are arranged to be relatively movable.

[0094] The above optional embodiments of the present application can achieve the following beneficial effects: In the locking state, the locking mechanism 60 fixedly connects the adjusting base 210 and the fixing base 110 to form a stable whole. The adjusting base 210 cannot move relative to the fixing base 110, effectively preventing the accidental separation of the adjusting base 210 and the fixing base 110, ensuring the long-term stable fixing of the wire harness 3, and avoiding circuit failures or safety hazards. In the releasing state, the locking mechanism 60 releases the locking between the adjusting base 210 and the fixing base 110, allowing the adjusting base 210 to move relative to the fixing base 110, so as to adjust the distance between the two according to the actual width of the wire harness 3 to achieve the best fixing effect. When it is necessary to replace the wire harness 3 or perform maintenance, unlocking the locking mechanism 60 can easily move the adjusting base 210 without completely disassembling the entire wire harness fixing device, simplifying the maintenance work and reducing the operation difficulty.

[0095] Furthermore, the fixing base 110 has a through accommodation space 111. Part of the adjusting base 210 is located on the first side of the accommodation space 111 and is connected to the second mounting assembly 220. Another part of the adjusting base 210 passes through the accommodation space 111 and extends to the second side of the accommodation space 111. Wherein, the adjusting base 210 is arranged to be relatively movable relative to the fixing base 110 to adjust the length of the adjusting base 210 extending to the second side of the accommodation space 111, thereby adjusting the width of the limiting space 300.

[0096] The above optional embodiments of the present application can achieve the following beneficial effects: The adjusting base 210 can freely slide in the accommodation space 111 to adjust the length extending to the other side of the accommodation space 111 as needed. The extending length of the adjusting base 210 directly determines the width of the limiting space 300, that is, the width of the wire harness 3 clamped by the wire harness fixing device.

[0097] Specifically, the adjusting base 210 can be moved by a slide rail, a rack, a screw rod or other mechanical transmission mechanisms.

[0098] Further, a fitting 112 is provided in the accommodation space 111. The fitting 112 is provided with a first fitting structure 113, and the adjustment base 210 is provided with a second fitting structure 230 that cooperates with the first fitting structure 113. When the locking mechanism 60 is in the released state, the fitting 112 is in a movable state. When the adjustment base 210 moves relative to the fixed base 110, it can drive the fitting 112 to move along a preset direction. When the locking mechanism 60 is in the locked state, the fitting 112 is in a fixed state to limit the movement of the adjustment base 210 relative to the fixed base 110.

[0099] The above optional embodiments of the present application can achieve the following beneficial effects: The fitting 112 cooperates with the first fitting structure 113 of the adjustment base 210 through the second fitting structure 230, so that the fitting 112 moves along with the adjustment base 210 when the adjustment base 210 moves. When the locking mechanism 60 locks the fitting 112 and the fitting 112 cannot move, the movement of the adjustment base 210 is also locked, that is, the position of the adjustment base 210 is fixed. Through the cooperation of the second fitting structure 230 and the first fitting structure 113, the smooth movement of the adjustment base 210 and the accuracy of the adjustment process are ensured, and the structural stress and wear that may be brought about by the direct connection of the adjustment base 210 with the locking mechanism 60 and the fixed base 110 are reduced, thereby extending the service life of the device and improving the reliability of the wire harness fixing.

[0100] It should be noted that the movement of the fitting 112 along the preset direction can include various types of movements. For example, the fitting 112 can rotate around its own central axis, or the fitting 112 can rotate around another object, or the fitting 112 can perform a linear movement in any direction such as the horizontal direction or the vertical direction.

[0101] Further, the fitting 112 is provided with at least one first fitting structure 113, and the adjustment base 210 is provided with a plurality of second fitting structures 230 arranged at intervals. During the movement of the adjustment base 210 relative to the fixed base 110, two adjacent first fitting structures 113 cooperate with the second fitting structures 230 in sequence to enable the fitting 112 to move along the preset direction.

[0102] The above optional embodiments of the present application can achieve the following beneficial effects: The plurality of second fitting structures 230 are distributed at intervals along the movement direction of the adjustment base 210, forming a dynamic interaction with the first fitting structure 113, ensuring that the fitting 112 can move smoothly and accurately positioned along the preset direction.

[0103] In this embodiment, the number of the first fitting structures 113 provided on the fitting 112 can be adjusted according to actual needs. Preferably, the first fitting structure 113 is provided with two or more, and is distributed along the movement direction of the fitting 112.

[0104] In an alternative embodiment of the present application, a plurality of first mating structures 113 are circumferentially arranged along the mating member 112. A plurality of second mating structures 230 are arranged on the adjusting base 210 in a horizontally distributed manner. The second mating structure 230 and the first mating structure 113 are tooth structures that mesh with each other. When the adjusting base 210 moves horizontally, the mating member 112 rotates around its own central axis. The second mating structure 230 meshes with the first mating structure 113. When the mating member 112 is locked, the mating member 112 cannot rotate. At this time, the adjusting base 210 is fixed and cannot move horizontally.

[0105] Further, the mating member 112 includes a spring piece 1121. The spring piece 1121 is connected to the side wall of the accommodating space 111. The first mating structure 113 is arranged on the spring piece 1121. When the spring piece 1121 is in a movable state, during the movement of the adjusting base 210 relative to the fixed base 110, a part of the spring piece 1121 moves along the height direction of the fixed base 110, so that two adjacent second mating structures 230 are sequentially matched with the first mating structure 113.

[0106] The above alternative embodiment of the present application can achieve the following beneficial effects: Through the elastic characteristics of the spring piece 1121, during the movement of the adjusting base 210, the spring piece 1121 undergoes corresponding deformation and recovery, so as to achieve precise matching with the second mating structure 230. When it is necessary to fix the position of the adjusting base 210, it is only necessary to restrict the movement of the spring piece 1121 in the height direction.

[0107] Specifically, in an exemplary embodiment of the present application, such as Figure 6 , Figure 7 , Figure 10As shown in the figure, F1 is the upward direction of the height of the fixed base 110, F2 is the downward direction of the height of the fixed base 110, F3 is the horizontal left direction (i.e., the direction in which the second mounting component 220 approaches the first mounting component 120), and F4 is the horizontal right direction (i.e., the direction in which the second mounting component 220 moves away from the first mounting component 120). When the adjusting base 210 starts to move in the F3 direction, the second mating structure 230 on the adjusting base 210 will come into contact and cooperate with the first mating structure 113 on the elastic piece 1121. Due to the movement of the adjusting base 210, the elastic piece 1121 will undergo elastic deformation along the height direction of the fixed base 110, that is, bend downward until the first mating structure 113 on the elastic piece 1121 disengages from the cooperation with one of the second mating structures 230 on the adjusting base 210. The adjusting base 210 continues to move in the F3 direction, and the elastic piece 1121 rebounds upward in the F1 direction. The first mating structure 113 on the elastic piece 1121 cooperates with another adjacent second mating structure 230. Through the alternating cooperation of two adjacent second mating structures 230 in the front and back with the same first mating structure 113 on the elastic piece 1121, the preset distance movement of the adjusting base 210 is realized, that is, a primary width fine-tuning of the limiting space 300 is realized (corresponding to the movement of the adjusting base 210 in the F3 direction, and this adjustment narrows the width of the limiting space 300).

[0108] Further, one of the first mating structure 113 and the second mating structure 230 is a mating groove, and the other of the first mating structure 113 and the second mating structure 230 is a mating protrusion.

[0109] The above optional embodiments of the present application can achieve the following beneficial effects: By setting the structure of the mating groove and the mating protrusion, the first mating structure 113 and the second mating structure 230 are mutually embedded mating structures. After adjusting the width of the limiting space 300, the position stability of the adjusting base 210 can be ensured through the embedded structure, and the position offset of the adjusting base 210 caused by the shaking of the device can be avoided.

[0110] It should be noted that in this embodiment, the mating groove and the mating protrusion should match each other, and the mating protrusion can have various cross-sectional shapes such as a quadrilateral, an arc, a semi-circle, etc.

[0111] Further, the first mating structure 113 and the second mating structure 230 are tooth structures that mesh with each other.

[0112] The above optional embodiments of the present application can achieve the following beneficial effects: By setting the first mating structure 113 and the second mating structure 230 in a meshing and mating manner, the connection stability between the adjusting base 210 and the fixed base 110 can be strengthened. After adjusting the position of the adjusting base 210, the position offset of the adjusting base 210 caused by shaking can be avoided.

[0113] Furthermore, the tooth structure is protrudingly arranged along the height direction of the fixed base 110 , and the tooth structure has two end surfaces arranged opposite to each other, one of which is an inclined surface, and the other end surface is a straight surface extending along the height direction of the fixed base 110 .

[0114] The above optional embodiments of the present application can achieve the following beneficial effects: the inclined surface of the tooth structure can play a guiding role in the movement of the adjustment base 210. When the adjustment base 210 starts to move, the inclined surface can help the second matching structure 230 on the adjustment base 210 to smoothly guide into the first matching structure 113. Even in the case of a slight alignment deviation, the inclined surface can make the adjustment base 210 move smoothly along the predetermined path through its guiding characteristics, reducing the jamming phenomenon during operation; the straight surface of the tooth structure plays a positioning and locking role. When the adjustment base 210 moves to a certain preset position, the straight surface forms a close contact with the second matching structure 230. Since the straight surface has a high verticality, it can effectively limit the further movement of the adjustment base 210, ensuring the stability of the adjustment base 210 at this position. Through the cooperation of the inclined surface and the straight surface, the smooth movement and precise positioning of the adjustment base 210 on the fixed base 110 can be achieved, the adjustment accuracy and stability of the wire harness fixing device can be improved, and the accidental movement of the adjustment mechanism 20 during use can be prevented.

[0115] like Figure 6 , Figure 7 As shown, in a preferred embodiment of the present application, of the two end surfaces of the tooth structure that are arranged opposite to each other, the end surface located on the left side is an inclined surface, and the end surface located on the right side is a straight surface.

[0116] Furthermore, the locking mechanism 60 includes a locking tongue 61. When the locking mechanism 60 is in a locked state, at least part of the locking tongue 61 is located in the accommodating space 111. In the height direction of the fixed base 110, at least part of the locking tongue 61 is located on the side of the spring sheet 1121 that is away from the second matching structure 230, and abuts against the spring sheet 1121.

[0117] The above-mentioned optional embodiments of the present application can achieve the following beneficial effects: the abutment between the locking tongue 61 and the spring piece 1121 prevents the spring piece 1121 from being deformed due to external force, that is, prevents the spring piece 1121 from moving in the height direction, thereby limiting any movement of the adjustment base 210 in the fixed base 110, ensuring the stable fixation of the adjustment mechanism 20, and enhancing the mechanical stability of the entire device.

[0118] Specifically, Figure 7 , Figure 8 , Figure 9As shown, preferably, the locking tongue 61 includes a body section and an operating section. The height of the operating section gradually decreases in the direction away from the body section, so that the operating section forms an inclined surface, which cooperates and abuts against the elastic piece 1121.

[0119] Furthermore, the locking mechanism 60 includes a locking and fixing structure 62. The locking and fixing structure 62 is connected to the locking tongue 61, and the locking tongue 61 is detachably connected to the fixed base 110 through the locking and fixing structure 62.

[0120] The above optional embodiments of the present application can achieve the following beneficial effects: The detachable connection design can improve the flexibility and maintenance convenience of the locking mechanism 60. When the locking tongue 61 or the locking and fixing structure 62 is damaged or needs to be replaced, the damaged parts can be easily disassembled for repair or replacement without replacing the entire fixing mechanism 10, reducing the maintenance cost and time.

[0121] In an exemplary embodiment of the present application, as Figure 8 shown, the locking and fixing structure 62 includes connection hooks provided on both sides of the locking tongue 61. As Figure 9 shown, when connected to the fixed base 110, the locking and fixing structure 62 extends into the accommodation space 111 in the F4 direction, and the connection hooks are clamped with the side wall of the accommodation space 111 to realize the connection between the locking mechanism 60 and the fixed base 110. To facilitate the insertion of the locking and fixing structure 62 into the accommodation space 111, the connection hooks on both sides can be elastic, so that the two connection hooks can approach each other relatively under external extrusion and automatically rebound outward after the extrusion force disappears.

[0122] In an optional embodiment of the present application, the locking mechanism 60 can also be fixedly connected to the fixed base 110. The locking tongue 61 has a locking state for locking the elastic piece 1121 and a release state away from the elastic piece 1121. The locking tongue 61 can be switched between the locking state and the release state by an activatable setting method, or the locking tongue 61 can be set as a telescopic structure for switching between the locking state and the release state.

[0123] Furthermore, the first mounting assembly 120 includes a first mounting plate 121 and a first limiting member 122 provided on the first mounting plate 121. A limiting space 300 is formed between the second mounting assembly 220 and the first limiting member 122.

[0124] The above optional embodiments of the present application can achieve the following beneficial effects: The first mounting plate 121 can be used to carry the wire harness 3, and the first limiting member 122 can be used to cooperate with the second mounting assembly 220 to form a limiting space 300. By adjusting the distance between the second mounting assembly 220 and the first limiting member 122, the width of the limiting space 300 can be adjusted, so as to adapt to wire harnesses 3 of different widths. The first limiting member 122 limits and fixes the wire harness 3 in the width direction of the wire harness 3, effectively preventing the wire harness 3 from shaking and falling off.

[0125] Among them, the first limiting member 122 can be a protruding structure, such as a baffle or a limiting post, and its specific geometric shape and size are determined according to the type and width of the wire harness to be fixed. Preferably, as Figure 1 , Figure 2 , Figure 13 shown, one end of the first limiting member 122 away from the first mounting plate 121 is folded towards the side where the second mounting assembly 220 is located, so that the first limiting member 122 forms a stop surface, and this stop surface can effectively prevent the wire harness 3 on the first mounting plate 121 from slipping out from above in the height direction.

[0126] Furthermore, the second mounting assembly 220 includes a second mounting plate 221 and a second limiting member 222 provided on the second mounting plate 221. The second limiting member 222 and the first limiting member 122 form a limiting space 300.

[0127] The above optional embodiments of the present application can achieve the following beneficial effects: The second mounting plate 221 can be used to carry the wire harness 3, and the second limiting member 222 can be used to cooperate with the first limiting member 122 to form a limiting space 300. By adjusting the distance between the second limiting member 222 and the first limiting member 122, the width of the limiting space 300 can be adjusted, so as to adapt to wire harnesses 3 of different widths. The second limiting member 222 and the first limiting member 122 are respectively located on both sides in the width direction of the wire harness 3, which can effectively prevent the wire harness 3 from shaking and falling off.

[0128] Among them, the second limiting member 222 can be a protruding structure, such as a baffle or a limiting post, and its specific geometric shape and size are determined according to the type and width of the wire harness to be fixed. Preferably, as Figure 1 , Figure 2 , Figure 13 shown, one end of the second limiting member 222 away from the second mounting plate 221 is folded towards the side where the first mounting assembly 120 is located, so that the second limiting member 222 forms a stop surface, and this stop surface can effectively prevent the wire harness 3 on the second mounting plate 221 from slipping out from above in the height direction.

[0129] In an exemplary embodiment of the present application, the second mounting plate 221 is arranged to move synchronously with the second limiting member 222, that is, the movement of the adjusting base 210 drives the second mounting plate 221 and the second limiting member 222 to move synchronously. The second mounting plate 221 and the first mounting plate 121 are on the same horizontal plane, so that the second mounting plate 221 and the first mounting plate 121 jointly form a bearing surface for bearing the wire harness 3.

[0130] Furthermore, the second mounting assembly 220 includes a limiting body 223. The limiting body 223 is connected to the first mounting plate 121, and a limiting space 300 is formed between the limiting body 223 and the first limiting member 122.

[0131] The above optional embodiment of the present application can achieve the following beneficial effects: By directly arranging the limiting body 223 connected to the first mounting plate 121, the limiting body 223 and the first limiting member 122 form a limiting space 300, which can simplify the structure of the second mounting assembly 220. By only adjusting the connection position between the limiting body 223 and the first mounting plate 121, the width of the limiting space 300 can be adjusted, effectively reducing the structural complexity and manufacturing cost.

[0132] Among them, the connection position between the limiting body 223 and the first mounting plate 121 can be adjusted in a variety of ways to make the distance between the limiting body 223 and the first limiting member 122 adjustable, so as to realize the width adjustment of the limiting space 300.

[0133] Furthermore, a plurality of first connection parts 123 are arranged on the first mounting plate 121. The plurality of first connection parts 123 are arranged at intervals. A second connection part 224 matching the first connection part 123 is arranged on the limiting body 223. The second connection part 224 can selectively cooperate with any one of the first connection parts 123 to adjust the distance between the limiting body 223 and the first limiting member 122.

[0134] The above optional embodiment of the present application can achieve the following beneficial effects: The plurality of first connection parts 123 arranged on the first mounting plate 121 can provide multiple connection points for the limiting body 223. By selectively cooperating the second connection part 224 with the first connection part 123 at any position, the limiting body 223 can be fixed at different positions on the first mounting plate 121, so as to adjust the distance between the limiting body 223 and the first limiting member 122, and further realize the width adjustment of the limiting space 300.

[0135] It should be noted that according to the width of the wire harness 3 to be fixed, the operator can quickly select the first connecting portion 123 for connecting the limiting body 223, and then connect the second connecting portion 224 of the limiting body 223 with the determined first connecting portion 123 to achieve the quick positioning and installation of the limiting body 223. Among them, the first connecting portion 123 and the second connecting portion 224 can be set as a mutually matching slot and buckle structure, a bolt connection structure, or a magnetic attraction connection structure. Preferably, as Figure 14 and Figure 15 shown, the first connecting portion 123 is a through hole, and the second connecting portion 224 is a buckle.

[0136] Furthermore, the installation mechanism 40 includes an installation body 41. The installation body 41 is connected to the fixed base 110. The installation body 41 includes a first stop section 411 close to the fixed base 110 and a second stop section 412 far from the fixed base 110. The radial dimension of the first stop section 411 is set to be larger than that of the second stop section 412. Wherein, an elastic stop structure 42 is provided on the outer peripheral surface of the second stop section 412. The elastic stop structure 42 is telescopically arranged along the radial direction of the second stop section 412. A clamping space is formed between the elastic stop structure 42 and the first stop section 411. The clamping space is used for clamping at least part of the installation base 50.

[0137] The above optional embodiments of the present application can achieve the following beneficial effects: The second stop section 412 with a smaller radial dimension can be used to penetrate through the installation base 50, and the first stop section 411 with a larger radial dimension can form a stop surface to prevent the installation base 50 from coming out. The elastic stop structure 42 can be radially telescoped. During the installation process, the elastic stop structure 42 can contract when being pressed, facilitating the insertion of the installation base 50. After the installation base 50 is in place, the elastic stop structure 42 returns to its original state to form an effective stop to ensure that the installation base 50 will not come out of the clamping space. The setting of the elastic stop structure 42 can facilitate the connection between the installation mechanism 40 and the installation bases 50 with different radial dimensions, effectively improving the practicality of the device.

[0138] Specifically, as Figure 10 shown, the first stop section 411 includes a stop body and stop flanges provided at both ends of the stop body. The second stop section 412 is connected to the stop body. The stop flanges are arranged along the circumferential direction of the second stop section 412, and there is a distance between the stop flanges and the outer peripheral surface of the second stop section 412. When connecting with the installation base 50, the stop flanges are in contact with the installation base 50. The stop flanges can have a certain elasticity so that the included angle between the stop flanges and the stop body can be variably set to adapt to installation bases 50 with different thicknesses.

[0139] Furthermore, the elastic stop structure 42 includes a plurality of stop protrusions 421 which are arranged in sequence along the axial direction of the second stop section 412, and, in the direction away from the fixed base 110, the sizes of the plurality of stop protrusions 421 in the radial direction of the second stop section 412 are gradually increased, so that two adjacent stop protrusions 421 form a stop step 422 facing the fixed base 110.

[0140] The above optional embodiments of the present application can achieve the following beneficial effects: through the plurality of stop steps 422 arranged in sequence along the axial direction of the second stop section 412, the clamping spaces with different axial lengths can be formed between the stop steps 422 at different positions and the second stop section 412, and the clamping spaces with different axial lengths can be adapted to installation bases 50 with different thicknesses, improving the practicability of the wire harness fixing device; the stop steps 422 can not only play a physical stop role, but also form a plurality of contact points between the installation base 50 and the installation mechanism 40, enhancing the stability and tightness of the clamping.

[0141] Specifically, in an exemplary embodiment of the present application, the elastic stop structure 42 includes three stop protrusions 421 arranged in sequence in the direction away from the fixed base 110. As Figure 11 shown, when the thickness of the installation base 50 is small, the bottom surface of the installation base 50 abuts against the end surface of the first stop protrusion 421 (i.e., the stop protrusion 421 closest to the first stop section 411). As Figure 12 shown, when the thickness of the installation base 50 increases, the bottom surface of the installation base 50 abuts against the end surface of the second stop protrusion 421.

[0142] The present application also provides a preferred embodiment of the wire harness fixing device to facilitate fixing the wire harness 3 on the installation base 50, which can be widely applied to the technical field of wire harness fixing. Specifically, as Figure 18 shown, at least one installation hole 501 is formed on the installation base 50, and the wire harness fixing device is connected to the installation base 50 through the installation hole 501. Optionally, the installation base 50 is a vehicle sheet metal.

[0143] Combined with Figures 1 to 12 、 Figure 16 、 Figure 17As shown, in this embodiment, the wire harness fixing device includes a fixing mechanism 10, an adjusting mechanism 20, a mounting mechanism 40, and a locking mechanism 60. Among them, the fixing mechanism 10 includes a fixing base 110 and a first mounting component 120 disposed on the fixing base 110. The mounting mechanism 40 is connected to the fixing base 110. The adjusting mechanism 20 includes an adjusting base 210 and a second mounting component 220 disposed on the adjusting base 210. The first mounting component 120 includes a first mounting plate 121 connected to the fixing base 110, and a first limiting member 122 disposed on the first mounting plate 121. The second mounting component 220 includes a second mounting plate 221 connected to the adjusting base 210, and a second limiting member 222 disposed on the second mounting plate 221. Among them, a limiting space 300 for accommodating the wire harness 3 is formed between the first limiting member 122 and the second limiting member 222.

[0144] Specifically, the fixing base 110 is provided with a receiving space 111, and a spring piece 1121 is disposed in the receiving space 111. The adjusting base 210 includes a toothed belt, and the toothed belt cooperates with the toothed structure on the spring piece 1121. The locking mechanism 60 includes a locking tongue 61 and a locking fixing structure 62.

[0145] Figure 1 The relative positions after the fixing mechanism 10, the adjusting mechanism 20, and the locking mechanism 60 are assembled are shown. The fixing mechanism 10 and the adjusting mechanism 20 are separately molded. The toothed belt of the adjusting base 210 is inserted into the spring piece 1121 of the fixing base 110, and the teeth on the spring piece 1121 cooperate with the teeth on the toothed belt to complete the assembly between the fixing mechanism 10 and the adjusting mechanism 20. By adjusting the insertion depth of the toothed belt, the width of the limiting space 300 is adjusted. When the first limiting member 122 and the second limiting member 222 are in contact with the wire harness 3, the assembly of the adjusting mechanism 20 is completed. The locking mechanism 60 is separately molded. During assembly, the locking tongue 61 of the locking mechanism 60 is in contact with the spring piece 1121 to fix the spring piece 1121. At the same time, the locking fixing structure 62 of the locking mechanism 60 is buckled on the fixing base 110 to complete the assembly of the locking mechanism 60.

[0146] Specifically, in this embodiment, the mounting hole 501 is an oblong hole. The mounting mechanism 40 includes a mounting body 41. The mounting body 41 is connected to the fixed base 110. The mounting body 41 includes a first stop section 411 close to the fixed base 110 and a second stop section 412 away from the fixed base 110. The radial dimension of the first stop section 411 is set to be larger than that of the second stop section 412. An elastic stop structure 42 is provided on the outer peripheral surface of the second stop section 412. The elastic stop structure 42 is telescopically arranged in the radial direction of the second stop section 412. A clamping space is formed between the elastic stop structure 42 and the first stop section 411. The clamping space is used to clamp at least part of the mounting base 50.
