A control wire harness positioning and fixing device

Abstract

This utility model relates to the field of wire harness positioning technology, specifically, to a control device for positioning and fixing wire harnesses. It includes two bracket bodies: a first bracket body and a second bracket body. Each bracket body has two connecting brackets fixedly connected to its surface. The connecting brackets in one bracket body are bolted to the connecting brackets in the other bracket body, allowing the two bracket bodies to merge and form an internal cavity structure for limiting and fixing the wire harness. By merging the two bracket bodies and using the bolted connections of the connecting brackets, a wrap-around fixing cavity for the wire harness is formed. Compared to traditional fixing methods such as cable ties, this significantly enhances the limiting ability of the wire harness.

This dual fixing method effectively resists sharp turns during vehicle operation.

Description

Technical Field

[0001] This utility model relates to the field of wire harness positioning technology, and more specifically, to a device for controlling the positioning and fixing of wire harnesses. Background Technology

[0002] With the continuous advancement of technology, electronic devices are becoming increasingly complex, and the electronic functions of automobiles are also constantly increasing. In these devices, a large number of wiring harnesses are used to connect various electronic components to achieve signal transmission and power supply. The reasonable arrangement and reliable fixation of wiring harnesses are crucial to the overall performance and reliability of the equipment. In the past, wiring harnesses were generally fixed using methods such as cable ties and clamps.

[0003] Considering that during vehicle operation, especially when the vehicle undergoes sharp turns, rapid acceleration, or sudden braking, the changes in vehicle body posture generate significant inertial forces and vibrations. Wiring harnesses secured by cable ties alone cannot provide effective restraint, and the entire wiring harness will shift. This shift will cause relative movement between the wiring harness end and the corresponding electrical interface. As the vehicle operates for longer periods, the insertion and extraction force at the interface will gradually decrease, eventually causing the wiring harness end to separate from the interface, leading to faults such as poor contact, signal interruption, or short circuit. Therefore, we propose a wiring harness positioning and fixing device. Utility Model Content

[0004] The purpose of this utility model is to solve the above-mentioned shortcomings and provide a control wire harness positioning and fixing device;

[0005] To achieve the above objectives, this utility model provides a control wire harness positioning and fixing device, including a bracket body, wherein there are two bracket bodies, namely a first bracket body and a second bracket body, and two connecting brackets are fixedly connected to the surface of each bracket body;

[0006] The connecting frame in one of the bracket bodies is bolted to the connecting frame in another bracket body so that the two bracket bodies are merged to form an internal cavity structure for limiting and fixing the wire harness;

[0007] Each bracket body has a connecting component fixedly connected to its top. The connecting component has a telescopic fixing component slidably disposed inside its cavity to cooperate with the bracket body to extend the length for fixing the wire harness. A mounting bracket is fixedly connected to the surface of the bracket body. The mounting bracket has bolt mounting holes for fixing the bracket body to the installation position of the electric vehicle. The inner wall of the bracket body is covered with anti-slip texture to enhance the constraint force on the wire harness.

[0008] The connecting frame of the two bracket bodies is fastened with bolts to close the two bracket bodies and form a fixed cavity, which clamps and fixes the surface of the wire harness. The mounting bracket on the surface of the bracket body is fixed to the preset position of the electric vehicle through the bolt mounting holes, and the entire device is firmly installed on the vehicle body. The double fixing method can effectively resist the large turns of the car during driving. The anti-slip texture covered by the inner wall of the bracket body and the inner wall of the semi-circular bracket increases the actual contact area with the surface of the wire harness, effectively increasing the static friction and further suppressing the axial sliding of the wire harness.

[0009] As a further improvement to this technical solution, the connecting component includes a limiting frame fixedly connected to the surface of the support body. A limiting groove is formed on the surface of the limiting frame. A telescopic fixing component is slidably connected to the inner wall of the limiting groove. The telescopic fixing component includes a slider slidably connected to the inner wall of the limiting groove. A moving rod is fixedly connected to the bottom of the slider. A semi-circular bracket is fixedly connected to the end of the moving rod. The semi-circular bracket is located on one side of the support body. The semi-circular bracket is semi-circular, and its inner wall is also provided with anti-slip texture.

[0010] Hold the semi-circular bracket and apply a pushing or pulling force. The semi-circular bracket drives the moving rod to move synchronously. The moving rod pushes the slider to slide along the limiting groove. When the semi-circular bracket moves to the target position, it can fix the surface of a long wire harness.

[0011] As a further improvement to this technical solution, the inner wall of the limiting groove is provided with multiple positioning grooves, and the inner cavity of the slider is provided with an elastic positioning rod, which can be embedded into the inner wall of the positioning groove under the action of spring force.

[0012] The slider of the telescopic fixing component slides into the limiting groove, and combined with the locking structure of the elastic positioning rod and the positioning groove, the user can easily hold the semi-circular bracket to adjust the position and lock it, so as to achieve the positioning and fixing of the wire harness.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] In this control harness positioning and fixing device, two main brackets are combined and connected by bolts to form a wrap-around fixing cavity for the harness. Compared with traditional fixing methods such as cable ties, this significantly enhances the limiting ability of the harness. At the same time, the mounting brackets on the surface of the main brackets are fixed to the preset position of the electric vehicle through bolt mounting holes, firmly installing the entire device on the vehicle body. The dual fixing method can effectively resist the inertial forces and vibrations generated during vehicle operation, such as sharp turns, rapid acceleration, or sudden braking, preventing the overall displacement of the harness and avoiding separation of the harness end and electrical interface due to relative movement. The design of the connecting component and the telescopic fixing component allows the device to flexibly adjust the fixing range according to the actual length of the harness. When the harness is long, the telescopic fixing component slides outward to increase the fixing support length and ensure the stability of long harnesses during vehicle operation.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example

[0025] Please see Figures 1-4 As shown, this embodiment provides a control wire harness positioning and fixing device, including a bracket body 1. There are two bracket bodies 1, namely a first bracket body and a second bracket body. Two connecting brackets 10 are fixedly connected to the surface of each bracket body 1.

[0026] The connecting frame 10 in a single bracket body 1 is bolted to the connecting frame 10 in another bracket body 1 so that the two bracket bodies 1 are merged to form an inner cavity structure for limiting and fixing the wire harness;

[0027] Each bracket body 1 is fixedly connected to the top of a connecting component 2. A telescopic fixing component 3 is slidably provided in the inner cavity of the connecting component 2 to cooperate with the bracket body 1 to extend the length of the wire harness fixing.

[0028] Gather the wire harness to be fixed and place it in the inner cavity of a single bracket body 1. Align and merge another bracket body 1 with the bracket body 1 where the wire harness has been placed. Tighten the connecting frame 10 of the two bracket bodies 1 with bolts to close the two bracket bodies 1 and form a fixed cavity to clamp and fix the surface of the wire harness. According to the length requirements of the wire harness, slide the telescopic fixing component 3 along the inner cavity of the connecting component 2 to adjust its fixed position on the surface of the wire harness. If the wire harness is long, slide the telescopic fixing component 3 outward to increase the fixed support length and improve stability. If the wire harness is short or does not need to be extended, keep the telescopic fixing component 3 in place or slide it in the opposite direction to retract it to adapt to different length requirements.

[0029] The improvement in this embodiment is as follows:

[0030] Considering that during vehicle operation, especially when the vehicle undergoes sharp turns, rapid acceleration, or sudden braking, the changes in vehicle body posture generate significant inertial forces and vibrations. Cable ties alone cannot effectively limit the movement of the wiring harness, causing overall displacement. This displacement leads to relative movement between the harness ends and their corresponding electrical interfaces. As the vehicle operates, the insertion and extraction force at the interfaces gradually weakens, eventually causing the harness ends to separate from the interfaces, resulting in poor contact, signal interruption, or short circuits. Therefore, by merging two bracket bodies 1 and connecting them with bolts to the connecting frame 10, a wrap-around fixing cavity for the wiring harness is formed. Compared to traditional fixing methods such as cable ties, this provides a more comprehensive solution. The fixed method significantly enhances the limiting ability of the wiring harness. At the same time, the mounting bracket 11 on the surface of the bracket body 1 is fixed to the preset position of the electric vehicle through the bolt mounting holes, so that the entire device is firmly installed on the vehicle body. The dual fixing method can effectively resist the inertial force and vibration generated during the operation of the vehicle, such as sharp turns, rapid acceleration or sudden braking, prevent the overall displacement of the wiring harness, and avoid the separation of the wiring harness end and the electrical interface due to relative movement. The design of the connecting component 2 and the telescopic fixing component 3 allows the device to flexibly adjust the fixing range according to the actual length of the wiring harness. When the wiring harness is long, the telescopic fixing component 3 can be slid outward to increase the fixing support length and ensure the stability of the long wiring harness during vehicle operation.

[0031] In order to ensure that the bracket body 1 can be fixed at the storage position of the electric vehicle's wiring harness when fixing the wiring harness, and that the wiring harness will not move due to the shaking of the vehicle, a mounting bracket 11 is fixedly connected to the surface of the bracket body 1. The mounting bracket 11 is provided with bolt mounting holes for fixing the bracket body 1 to the installation position of the electric vehicle. The bracket body 1 is fixed to the preset installation position of the electric vehicle using bolts through the bolt holes of the mounting bracket 11.

[0032] In order to increase the constraint force on the wire harness by the bracket body 1, the inner wall of the bracket body 1 is covered with anti-slip texture 12 to enhance the constraint force on the wire harness. The anti-slip texture 12 increases the actual contact area between the inner wall of the bracket body 1 and the surface of the wire harness through the grid or granular protrusion structure. The increase in contact area directly increases the static friction force, thereby suppressing the axial sliding of the wire harness.

[0033] In order to enable the telescopic fixing component 3 to slide within the inner cavity of the connecting component 2, it is necessary to further disclose the components of the connecting component 2. Therefore, the connecting component 2 includes a limiting frame 21 fixedly connected to the surface of the bracket body 1. A limiting groove 210 is formed on the surface of the limiting frame 21, and the telescopic fixing component 3 is slidably connected to the inner wall of the limiting groove 210. By manually moving the telescopic fixing component 3, it slides within the inner wall of the limiting groove 210, thereby extending the length of the wire harness fixing.

[0034] In order for the telescopic fixing component 3 to cooperate with the connecting component 2 to fix the wire harness, it is necessary to further disclose the parts of the telescopic fixing component 3. Therefore, the telescopic fixing component 3 includes a slider 33 that is slidably connected to the inner wall of the limiting groove 210. A moving rod 32 is fixedly connected to the bottom of the slider 33, and a semi-circular bracket 31 is fixedly connected to the end of the moving rod 32. The semi-circular bracket 31 is located on one side of the bracket body 1. When the user holds the semi-circular bracket 31 and applies a pushing or pulling force, the semi-circular bracket 31 drives the moving rod 32 to move synchronously. The moving rod 32 pushes the slider 33 to slide along the limiting groove 210. When the semi-circular bracket 31 moves to the target position, the surface of the long wire harness can be fixed.

[0035] In order to make the semi-circular bracket 31 fit against the surface of the wire harness after it is moved to a suitable position and to fix the wire harness, the semi-circular bracket 31 is made into a semi-circular shape, and its inner wall is also provided with anti-slip texture 12.

[0036] The bracket body 1 is composed of a first bracket body and a second bracket body. Each bracket body 1 has a connecting component 2 and a telescopic fixing component 3 on its surface. When the two bracket bodies 1 are combined through the connecting frame 10, the two semi-circular brackets 31 automatically form a closed ring, which fits against the surface of the wire harness and fixes the surface of the wire harness.

[0037] To prevent the slider 33 from sliding against the inner wall of the limiting groove 210 due to the movement of subsequent vehicles after the semi-annular bracket 31 has been moved to the appropriate position, multiple positioning grooves 211 are provided on the inner wall of the limiting groove 210. The inner cavity of the slider 33 is provided with a spring positioning rod 330, which can be embedded into the inner wall of the positioning groove 211 under the action of spring force. By setting a spring inside the slider 33 and connecting it with the spring positioning rod 330, when the semi-annular bracket 31 needs to move, the spring positioning rod 330 is pushed back into the inner cavity of the slider 33. After the semi-annular bracket 31 reaches the preset position, the force on the slider 33 is released. At this time, under the action of spring rebound force, the spring positioning rod 330 is embedded into the inner cavity of the positioning groove 211, thus locking the position of the semi-annular bracket 31.

[0038] In practical use, the wiring harness positioning and fixing device of this utility model gathers the wiring harness to be fixed and places it in the inner cavity of the first bracket body 1. The second bracket body 1 is aligned with the first bracket body 1, and the connecting frame 10 is tightened with bolts to close the two bracket bodies 1 to form a fixing cavity, which clamps and fixes the surface of the wiring harness. According to the required length of the wiring harness, the semi-circular bracket 31 is held and the elastic positioning rod 330 is pushed to retract into the inner cavity of the slider 33, so that the slider 33 slides along the limiting groove 210 to adjust the position of the semi-circular bracket 31 on the surface of the wiring harness. When the semi-circular bracket 31 moves to the target position, the force on the slider 33 is released. Under the action of the spring rebound force, the elastic positioning rod 330 is embedded into the inner cavity of the positioning groove 211, locking the position of the semi-circular bracket 31. Through the bolt holes of the mounting bracket 11, the bracket body 1 is fixed to the preset installation position of the electric vehicle with bolts.
