Description

Technical Field

[0001] This application relates to the field of automotive wiring harness layout technology, specifically an anti-rotation bracket for automotive chassis wiring harnesses. Background Technology

[0002] The chassis of a car is a relatively small and complex space with many mechanical parts and pipes. Wiring harnesses need to be arranged in a specific path within the chassis to avoid interference with other parts and to ensure that the wiring harnesses are not damaged by vibration, friction or other reasons during the car's operation.

[0003] An existing patent (publication number: CN220764296U) discloses an anti-rotation bracket for automotive chassis wiring harnesses. This bracket is used to fix automotive chassis wiring harnesses in confined spaces above the chassis. The anti-rotation bracket includes a bracket body, a first through hole, and a second through hole. The bracket body has a "Z"-shaped structure, with the first and second through holes respectively at both ends. The first and second through holes penetrate the upper and lower surfaces of the bracket body, respectively, and are not on the same horizontal plane. The automotive chassis wiring harness is fixed within the first through hole, and the second through hole is fixed above the chassis. Compared with existing technologies, this invention can achieve anti-rotation by cooperating with the vehicle's body mounting boss through a first limiting part while fixing the wiring harness routing. This solves the problem of difficult chassis wiring harness layout caused by interference due to complex environments during the wiring harness arrangement process.

[0004] Because there are many chassis wiring harnesses, existing anti-rotation brackets usually require multiple wiring harnesses to be bundled together and fixed to the bracket during use. Although this can meet the fixing requirements to a certain extent, it brings great inconvenience to the later maintenance of the car. Maintenance personnel have difficulty quickly distinguishing the functions and routes of different wiring harnesses and need to spend a lot of time untying the bundles and checking each wiring harness one by one. This not only increases the workload of maintenance, but also prolongs the maintenance time and reduces maintenance efficiency. Secondly, during the layout of automotive chassis wiring harnesses, it is often necessary to bend and turn them according to the spatial structure of the chassis and the layout of the electrical system to adapt to different installation positions and routing requirements. Existing anti-rotation brackets usually have a fixed orientation during installation. Once installed, it is difficult to flexibly adjust the direction of the wiring harness according to actual needs. Before installing the bracket, the routing of the wiring harness and the installation position of the bracket must be planned, which may result in the wiring harness not being laid out according to the expected path or the bracket not being able to be installed normally. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides an anti-rotation bracket for automotive chassis wiring harnesses, which has advantages such as easy adjustment and solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this application provides the following technical solution: an anti-rotation bracket for automotive chassis wiring harnesses, comprising a mounting plate, wherein a rotating shaft is rotatably connected to the middle of the mounting plate and is perpendicularly arranged thereto, and a cable fixing assembly is fixedly connected to the end of the rotating shaft away from the mounting plate; A locking mechanism is fixedly connected to the upper surface of the mounting plate; The locking mechanism includes a fixed wheel that is fixedly connected to the outer surface of a rotating shaft, and a set of locking grooves arranged in a circle are opened on the outer surface of the fixed wheel; The locking mechanism also includes two sleeves symmetrically arranged on the upper surface of the mounting plate. The two sleeves are symmetrically arranged and have locking rods slidably inserted into them along the length of the mounting plate. Each locking rod is fixedly connected to a compression spring between itself and its corresponding sleeve. The ends of the two locking rods that are close to each other are fixedly connected to locking balls, and the two locking balls are slidably inserted into their corresponding locking grooves.

[0007] Furthermore, the locking mechanism also includes two symmetrically arranged levers. The two levers are slidably connected to the mounting plate, and each lever is fixedly connected to its corresponding locking rod.

[0008] With the above solution, when it is necessary to adjust the orientation of the cable fixing component, the user can move the lever to move the locking ball out of the locking groove, thereby releasing the locking of the fixing wheel and the rotating shaft, making it convenient to rotate the cable fixing component; after the adjustment is completed, the lever is released, and the locking ball is reinserted into the locking groove under the action of the compression spring to achieve locking, which is simple and convenient to operate.

[0009] Furthermore, the cable fixing assembly includes a base, a sealing block is hinged to the upper surface of the base, and a semi-circular groove is opened on the side of the sealing block and the base that are close to each other. The two semi-circular grooves are on the same axis. A set of lock holes arranged at equal intervals are fixedly installed on one side of the sealing block. A set of fixing rods is fixedly connected to the upper surface of the base. Each fixing rod is inserted into its corresponding lock hole, and a nut is threaded to the top of each fixing rod.

[0010] The above method involves placing the wire harness in the semi-circular groove of the base, then closing the sealing block so that the two semi-circular grooves enclose the wire harness. The fixing rod is then inserted into the corresponding locking hole and the nut is tightened to fix the wire harness. This fixing method allows each wire harness to be fixed individually, making it easier to quickly distinguish the function and direction of different wire harnesses during later maintenance and improving maintenance efficiency.

[0011] Furthermore, the cable fixing assembly also includes a trapezoidal groove formed on one side of the base along its length, and a trapezoidal protrusion fixedly connected to the other side of the base along its length.

[0012] The above solution allows users to easily expand the system according to the actual number of cables, connecting multiple cable fixing components sequentially via trapezoidal grooves and trapezoidal protrusions to meet the fixing needs of different numbers of cable harnesses.

[0013] Furthermore, the cable fixing assembly also includes a connecting shaft rotatably connected to the bottom of the base, the connecting shaft being arranged along the length of the base, and arc-shaped locking hooks fixedly connected to both ends of the connecting shaft radially, and locking rings fixedly connected to the front and rear ends of the base.

[0014] With the above solution, when the cable fixing components are expanded, the arc-shaped locking hooks are flipped and their corresponding locking rings are interference-fitted, which can ensure that the two ends of adjacent cable fixing components are on the same reference plane, making the connection of multiple cable fixing components more stable and ensuring the reliability of the wire harness fixing.

[0015] Furthermore, each of the semicircular grooves has a rubber pad that is fixedly connected to its inner wall.

[0016] The above solution increases the friction between the rubber pad and the wire harness, preventing the wire harness from sliding in the semi-circular groove. It also provides cushioning and protection, preventing damage to the wire harness during the fixing process.

[0017] Furthermore, the mounting plate is provided with integrally formed fixing ears at both ends.

[0018] The above solution facilitates the fixing of the mounting plate to the car chassis. The fixing ears can increase the contact area between the mounting plate and the chassis, thereby improving the stability of the fixation.

[0019] Compared with the prior art, the technical solution of this application has the following beneficial effects: This anti-rotation bracket for automotive chassis wiring harnesses features a rotatable shaft in the center of the mounting plate, on which a cable fixing component is mounted. Users can easily release the shaft by moving a lever, rotate the cable fixing component to the desired orientation, and then release the lever to lock it in place. This allows the orientation of the cable fixing component to be flexibly adjusted according to the chassis space structure and electrical system layout, eliminating the need for precise planning of the wiring harness routing and bracket installation position before installation. This effectively solves the problem of existing anti-rotation brackets having a fixed orientation and being unable to adapt to the turning and bending requirements of wiring harnesses. The cable securing assembly uses a base hinged to a sealing block, allowing each cable harness to be secured individually. This securing method avoids the situation where multiple cable harnesses are bundled together. During later vehicle maintenance, maintenance personnel can quickly distinguish the function and route of different cable harnesses without spending a lot of time untying the bundles and checking them one by one, greatly improving maintenance efficiency. The base of the cable fixing assembly has a trapezoidal groove on one side and a trapezoidal protrusion on the other side, which allows users to connect multiple cable fixing assemblies in sequence through the trapezoidal groove and the trapezoidal protrusion according to the actual number of cables, so as to meet the fixing needs of different numbers of wire harnesses. The arc-shaped locking hook cooperates with the locking rings at the front and rear ends of the base. After expansion, the arc-shaped locking hook flips and is interference-fitted with the locking ring to ensure that the two ends of adjacent cable fixing assemblies are on the same reference plane, making the connection of multiple components more stable.

[0022] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0023] Please see Figures 1-5This embodiment of an anti-rotation bracket for automotive chassis wiring harness includes a mounting plate 1. A rotating shaft 2 is rotatably connected to the middle of the mounting plate 1 and is perpendicular to it. A cable fixing assembly 3 is fixedly connected to the end of the rotating shaft 2 away from the mounting plate 1. A locking mechanism 4 is fixedly connected to the upper surface of the mounting plate 1. The locking mechanism 4 includes a fixed wheel 401 fixedly connected to the outer surface of the rotating shaft 2. A set of locking grooves 402 arranged in a circle are opened on the outer surface of the fixed wheel 401.

[0024] The locking mechanism 4 also includes two sleeves 403 symmetrically arranged on the upper surface of the mounting plate 1. The two sleeves 403 are symmetrically arranged and have locking rods 404 slidably inserted into them along the length of the mounting plate 1. Each locking rod 404 is fixedly connected to a compression spring 405 between itself and its corresponding sleeve 403. The ends of the two locking rods 404 that are close to each other are fixedly connected to locking balls 406. The two locking balls 406 are slidably inserted into their corresponding locking grooves 402. With the above arrangement, the user can easily adjust the orientation of the cable fixing assembly 3 and facilitate the arrangement of the cable harness when turning. After adjustment, the locking balls 406 are inserted into the locking grooves 402 under the action of the compression springs 405 to lock the fixing wheel 401 and the rotating shaft 2, preventing the cable fixing assembly 3 from rotating during use and ensuring the stability of the cable harness arrangement.

[0025] The locking mechanism 4 also includes two symmetrically arranged levers 407. The two levers 407 are symmetrically arranged and are slidably connected to the mounting plate 1. The two levers 407 are fixedly connected to their corresponding locking rods 404. When it is necessary to adjust the orientation of the cable fixing assembly 3, the user can move the levers 407 to make the locking rods 404 move the locking ball 406 out of the locking groove 402, thereby releasing the locking of the fixed wheel 401 and the rotating shaft 2, making it convenient to rotate the cable fixing assembly 3. After the adjustment is completed, the levers 407 are released, and the locking ball 406 is reinserted into the locking groove 402 under the action of the compression spring 405 to achieve locking. The operation is simple and convenient.

[0026] The cable fixing assembly 3 includes a base 301, with a closing block 302 hinged to the upper surface of the base 301. Both the closing block 302 and the base 301 have semi-circular grooves 303 on their adjacent sides, with the two semi-circular grooves 303 on the same axis. A set of equally spaced locking holes 304 are fixedly installed on one side of the closing block 302. A set of fixing rods 305 are fixedly connected to the upper surface of the base 301. Each fixing rod 305 is inserted into its corresponding locking hole 304, and a nut 306 is threaded onto the top of each fixing rod 305. The cable harness is placed in the semi-circular groove 303 of the base 301, then the closing block 302 is closed, so that the two semi-circular grooves 303 enclose the cable harness. The fixing rod 305 is then inserted into its corresponding locking hole 304, and the nut 306 is tightened to fix the cable harness. This fixing method allows for individual fixing of each cable harness, facilitating quick differentiation of the function and direction of different cable harnesses during later maintenance, thus improving maintenance efficiency.

[0027] The cable fixing assembly 3 also includes a trapezoidal groove 307 formed along the length of one side of the base 301, and a trapezoidal protrusion 308 fixedly connected along the length of the other side of the base 301. This allows users to easily expand the assembly according to the actual number of cables, connecting multiple cable fixing assemblies 3 sequentially through the trapezoidal groove 307 and the trapezoidal protrusion 308 to meet the fixing requirements of different numbers of cable harnesses. The cable fixing assembly 3 also includes a connecting shaft 309 rotatably connected to the bottom of the base 301. The connecting shaft 309 is set along the length of the base 301, and arc-shaped locking hooks 310 are fixedly connected to both ends of the connecting shaft 309 radially. Locking rings 311 are fixedly connected to the front and rear ends of the base 301. When the cable fixing assembly 3 is expanded, the arc-shaped locking hooks 310 are flipped and interlocked with the corresponding locking rings 311, ensuring that the two ends of adjacent cable fixing assemblies 3 are on the same reference plane, making the connection of multiple cable fixing assemblies 3 more stable and ensuring the reliability of cable harness fixing.

[0028] Each semicircular groove 303 has a rubber pad 5 fixedly connected to its inner wall. The rubber pad 5 can increase the friction between the rubber pad and the wire harness, prevent the wire harness from sliding in the semicircular groove 303, and also play a buffering and protective role to avoid damage to the wire harness during the fixing process. The mounting plate 1 has integrally formed fixing ears 6 at both ends, which makes it easy to fix the mounting plate 1 to the car chassis. The fixing ears 6 can increase the contact area between the mounting plate 1 and the chassis and improve the stability of the fixing.

[0029] The working principle of the above embodiment is as follows: A rotating shaft 2 is rotatably connected to the middle of the mounting plate 1 and is perpendicular to it. The end of the rotating shaft 2 away from the mounting plate 1 is fixedly connected to the cable fixing assembly 3. When it is necessary to adjust the orientation of the cable fixing assembly 3, since the locking mechanism 4 locks the rotating shaft 2 in the initial state, the lock must first be released. When the user moves the lever 407, the lever 407 drives the locking rod 404 to slide along the length direction of the mounting plate 1 in the two sleeves 403 symmetrically arranged on the upper surface of the mounting plate 1. During the sliding of the locking rod 404, the compression spring 405 is compressed. At the same time, the ends of the two locking rods 404 that are close to each other are fixedly connected to the locking ball 406. The sliding of the locking rod 404 will drive the locking ball 406 to move out from a set of circumferentially arranged locking grooves 402 opened on the outer surface of the fixed wheel 401, releasing the lock on the fixed wheel 401 and the rotating shaft 2. After the rotating shaft 2 is released, the user can easily rotate the cable fixing assembly 3 to reach the appropriate orientation according to the spatial structure of the car chassis and the layout of the electrical system.

[0030] When the cable fixing assembly 3 is rotated to the appropriate position, the user releases the lever 407. The compressed spring 405 returns to its original state, generating a spring force that pushes the locking lever 404 to slide in the opposite direction. The locking lever 404 drives the locking ball 406 to re-insert into the corresponding locking groove 402, thereby locking the fixing wheel 401 and the rotating shaft 2 again, preventing the cable fixing assembly 3 from rotating during use and ensuring the stability of the wire harness arrangement.

[0031] The wire harness that needs to be fixed is placed in the semi-circular groove 303 of the base 301, and the closing block 302 is closed so that the two semi-circular grooves 303 wrap around the wire harness. A set of lock holes 304 arranged at equal intervals are fixedly installed on one side of the closing block 302. A set of fixing rods 305 are fixedly connected to the upper surface of the base 301. Each fixing rod 305 is inserted into its corresponding lock hole 304. Then, the nut 306 is tightened on the top of each fixing rod 305 to fix the wire harness. Fixing each wire harness individually makes it easier to quickly distinguish the function and direction of different wire harnesses during later maintenance, thus improving maintenance efficiency.

[0032] When a large number of cables need to be fixed to the car chassis, the cable fixing assembly 3 can be expanded. One side of the base 301 of the fixing assembly has a trapezoidal groove 307 along its length, and the other side of the base 301 is fixedly connected to a trapezoidal protrusion 308 along its length. Users can connect multiple cable fixing assemblies 3 in sequence through the trapezoidal groove 307 and the trapezoidal protrusion 308 according to the actual number of cables to meet the fixing requirements of different numbers of wire harnesses. After the cable fixing assembly 3 is expanded, the arc-shaped locking hook 310 is flipped to allow it to be interference-fitted with the corresponding locking ring 311. This ensures that the two ends of adjacent cable fixing assemblies 3 are on the same reference plane, making the connection of multiple cable fixing assemblies 3 more stable and ensuring the reliability of wire harness fixing.
