[0002] The modular connection structure of the distributed integrated wiring harness for engineering vehicles is a structural form that divides the vehicle wiring harness into modules according to function and connects the modules through specific interfaces.

[0003] To address the aforementioned issues, existing patents have provided solutions. However, existing integrated wire harnesses lack a modular connection structure, resulting in reduced assembly efficiency. Furthermore, the increased manual operation leads to a higher assembly error rate, thereby reducing the convenience of connecting or maintaining the wire harness.

[0004] To address this, a modular connection structure for distributed integrated wiring harnesses in engineering vehicles is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a modular connection structure for distributed integrated wiring harnesses in engineering vehicles. This structure can solve the problem that existing vehicle electrical systems lack a modular connection structure, which leads to reduced wiring harness assembly efficiency. At the same time, the increase in manual operation leads to an increased assembly error rate, thereby reducing the convenience of wiring harness connection or maintenance.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a modular connection structure for an integrated wiring harness distributed in engineering vehicles, comprising a main wiring harness, a connection mechanism fixedly connected to the front side of the main wiring harness, an integrated mechanism snapped into the inner side of the connection mechanism, the connection mechanism comprising a lower mounting shell, a plurality of connecting shells, a sliding hole and a pressing rod, the lower mounting shell being fixedly connected to the front side of the main wiring harness, the connecting shells being fixedly connected to the inner side of the lower mounting shell, the sliding hole being opened on the inner side of the top of the connecting shell, and the pressing rod being slidably connected to the inner side of the sliding hole.

[0007] Preferably, the integrated mechanism includes a connector, a mounting hole, a return spring, a lower pressure plate, an integrated wiring harness, and a connector head, wherein the connector is snapped into the inner side of the connecting housing.

[0008] Preferably, the mounting hole is located on the inner side of the top of the connector, the reset spring is fixedly connected to the inner side of the mounting hole, and the lower pressure plate is fixedly connected to the top of the reset spring.

[0009] Preferably, the top of the lower pressure plate contacts the bottom of the pressing rod, the integrated wire harness is fixedly connected to the front side of the connector, and the connector head is installed on the front side of the integrated wire harness.

[0010] Preferably, hinges are installed on both sides of the rear top of the lower mounting housing, and the surface of the hinges is coated with an anti-corrosion coating.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. The connection mechanism of this application constructs a standardized module docking carrier through the combination of a lower mounting shell, a connecting shell, and a pressing rod. The lower mounting shell is fixedly connected to the main wiring harness, providing a unified installation benchmark for each integrated mechanism and avoiding the cumbersome process of fixing the wiring harness point by point in the traditional method. The connecting shell serves as the snap-fit ​​body of the connector, and together with the pressing rod in the sliding hole, it forms a convenient operation mode of pressing to unlock and plugging and unplugging. Compared with the traditional welding or multi-bolt fixing structure, it shortens the docking time between the integrated wiring harness and the main wiring harness.

[0016] 2. The integrated mechanism of this application, through the fixed connection of the integrated wire harness and the connector, reduces the probability of wire harness detachment when the wire harness of the engineering vehicle is subjected to accidental pulling, such as equipment movement, bumps and collisions, compared with the traditional method of direct welding of wire harness. At the same time, the standardized design of the connector avoids forced plugging and unplugging due to interface mismatch, reduces terminal wear, and extends the service life of the connector from the traditional 3 years to more than 5 years, thereby reducing equipment replacement costs.

Detailed Implementation

[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] Please see Figure 1-5 The present invention provides the following technical solution:

[0025] A modular connection structure for an integrated wiring harness distributed in engineering vehicles includes a main wiring harness 1. A connection mechanism 2 is fixedly connected to the front side of the main wiring harness 1. An integrated mechanism 3 is snapped into the inner side of the connection mechanism 2. The connection mechanism 2 includes a lower mounting shell 21, several connecting shells 22, a sliding hole 23, and a pressing rod 24. The lower mounting shell 21 is fixedly connected to the front side of the main wiring harness 1. The connecting shells 22 are fixedly connected to the inner side of the lower mounting shell 21. The sliding hole 23 is opened on the inner side of the top of the connecting shell 22. The pressing rod 24 is slidably connected to the inner side of the sliding hole 23.

[0026] In this embodiment: the main wiring harness 1 plays a crucial role in centrally carrying and transmitting circuit signals and power, integrating the circuits required by various systems of the engineering vehicle, avoiding the messy wiring caused by scattered wiring, and greatly simplifying the wiring layout inside the engineering vehicle. The lower mounting shell 21, through its fixed connection with the main wiring harness 1, provides a stable mounting reference for the entire connection mechanism 2, preventing displacement or loosening of the connection mechanism 2 due to vibration during the operation of the engineering vehicle, and ensuring the structural stability of the connection part. The connection shell 22 adopts a multi-quantity design, which can simultaneously connect to multiple integrated mechanisms 3 to meet the needs of multi-functional modules of the engineering vehicle, such as hydraulic control, lighting systems, etc. The independent wiring connection requirements of the dashboard, etc., enable the modular distribution of the wiring harness, which facilitates the addition or removal of the integrated mechanism 3 according to the vehicle function upgrade in the future, thereby improving the structural expandability. The sliding hole 23 provides a vertical sliding track for the pressing rod 24, which prevents the pressing rod 24 from deviating or getting stuck during operation, and ensures that the pressing action can be applied to the integrated mechanism 3 to achieve quick unlocking or locking. The pressing rod 24 adopts a sliding design, and the staff only needs to press or release the pressing rod 24 to quickly complete the locking and fixing or unlocking and separating of the integrated mechanism 3 without the need to use screwdrivers, wrenches and other tools, which greatly simplifies the assembly and maintenance process, and is especially suitable for the operation requirements in the confined space of engineering vehicles.

[0027] Specifically, such as Figure 3 , Figure 4 As shown, the integrated mechanism 3 includes a connector 31, a mounting hole 32, a return spring 33, a lower pressure plate 34, an integrated wire harness 35, and a connector 36. The connector 31 is snapped into the inside of the connecting housing 22.

[0028] Specifically, such as Figure 3 , Figure 4 As shown, the mounting hole 32 is opened on the inner side of the top of the connector 31, the reset spring 33 is fixedly connected to the inner side of the mounting hole 32, and the lower pressure plate 34 is fixedly connected to the top of the reset spring 33.

[0029] Specifically, such as Figure 3 , Figure 4 As shown, the top of the lower pressure plate 34 contacts the bottom of the pressing rod 24, the integrated wire harness 35 is fixedly connected to the front side of the connector 31, and the connector head 36 is installed on the front side of the integrated wire harness 35.

[0030] In this embodiment: by using a snap-fit ​​connection for the connector 31, no auxiliary tools such as screws or clips are needed. Workers can quickly connect or disconnect the connector 31 from the connecting housing 22, significantly improving assembly efficiency on the engineering vehicle production line and facilitating emergency maintenance during field operations. The mounting hole 32 provides a fixed mounting space for the return spring 33. The return spring 33 can be compressed when the worker presses the pressing rod 24, allowing the connector 31 to be easily inserted into or removed from the connecting housing 22. After releasing the pressing rod 24, the return spring 33 rebounds elastically, pushing the lower pressure plate 34 upwards to press the pressing rod 24, thereby achieving connection between the connector 31 and the connecting housing 22. The automatic clamping of the 2nd component eliminates the need for manual additional fixing. The lower pressure plate 34 can evenly transmit the vertical pressure applied by the pressing rod 24 to the return spring 33. The integrated wiring harness 35 integrates multiple wires required for a certain functional module of the engineering vehicle, such as the lighting system or control panel, into a single bundle, avoiding the problems of messy and interfering traditional scattered wiring. This significantly improves the regularity of the internal wiring layout of the vehicle and makes it easier for staff to quickly identify the function of the wiring, reducing the difficulty of maintenance. The connector 36 adopts a standardized interface design, which can be matched with the interfaces of corresponding functional modules of the engineering vehicle, such as sensors and actuators, avoiding module damage caused by incorrect wiring. At the same time, the standardized design facilitates mass production and replacement, reducing the cost of spare parts.

[0031] Specifically, such as Figure 5 As shown, hinges 4 are installed on both sides of the top rear side of the lower mounting shell 21, and the surface of the hinges 4 is coated with anti-corrosion paint.

[0032] Specifically, such as Figure 5 As shown, a protective cover 5 is fixedly connected to the front side of the top of the hinge 4, and the protective cover 5 is rotatably connected to the top of the lower mounting shell 21.

[0033] In this embodiment: By setting the hinge 4, the protective cover 5 can rotate flexibly around the hinge 4, realizing the opening and closing of the protective cover 5. This facilitates the installation, inspection and maintenance of the connecting mechanism 2 and the integrated mechanism 3 by the staff. By setting the anti-corrosion coating, it can effectively resist the erosion of harmful substances such as moisture, dust and corrosive gases that may exist in the working environment of the engineering vehicle, slow down the rusting and aging speed of the hinge 4, and extend its service life. By setting the protective cover 5, it can protect the connecting mechanism 2 and the integrated mechanism 3 inside the lower mounting shell 21. During the operation of the engineering vehicle, the protective cover 5 can prevent external dust, mud, rainwater, oil and other impurities from entering the connection parts, avoid impurities adhering to the surface of the connecting parts and causing poor contact, prevent the occurrence of faults such as short circuit or open circuit, and ensure the stability and safety of the circuit connection.

[0034] Specifically, such as Figure 2As shown, a protective pad 6 is fitted on the top of the pressing rod 24, and the surface of the protective pad 6 is engraved with anti-slip texture.

[0035] Specifically, such as Figure 5 As shown, both sides of the integrated wire harness 35 are fixedly connected with retaining rings 7. The side of the retaining ring 7 away from the integrated wire harness 35 is welded to the front surface of the connector 31 and the rear surface of the connector head 36. The surface of the retaining ring 7 is coated with anti-corrosion paint.

[0036] In this embodiment: by setting a protective pad 6, the contact comfort between the hand and the pressing rod 24 is increased when the operator presses the pressing rod 24, avoiding hand discomfort caused by the hard material of the pressing rod 24 and improving the operating experience. By setting an anti-slip texture, the friction between the hand and the protective pad 6 can be significantly increased, preventing the hand from slipping during the pressing process and ensuring that the pressing operation can be completed effectively. By setting a fixing ring 7, the connection between the integrated wire harness 35 and the connector 31 and the connector head 36 can be effectively prevented from loosening or breaking due to vibration during the driving or operation of the engineering vehicle. By setting an anti-corrosion coating, it can resist the erosion of the harsh external environment, prevent the fixing ring 7 from rusting and being damaged, and extend its service life.

[0037] Working Principle: First, the operator holds the connector 31 and aligns it with the opening on the front side of the connecting housing 22. Then, the connector 31 is inserted into the inside of the connecting housing 22. At this time, the inner wall of the connecting housing 22 presses against the lower pressure plate 34, causing the lower pressure plate 34 to compress the return spring 33 downwards, thus smoothly guiding the connector 31 into the connecting housing 22. After the top of the lower pressure plate 34 aligns with the sliding hole 23, the return spring 33 begins to rebound under its own elasticity, pushing the lower pressure plate 34 vertically upwards. The top of the lower pressure plate 34 presses against the pressing rod 24, causing the pressing rod 24 to return to its initial position along the sliding hole 23. Simultaneously, the rebound tension of the return spring 33 is transmitted through the lower pressure plate 34 to the contact area between the pressing rod 24 and the connecting housing 22, forming a stable clamping force and firmly fixing the connector 31 inside the connecting housing 22. Then, the operator uses the connector 36 installed on the front side of the integrated wiring harness 35 to interface with the functional modules of the engineering vehicle, such as the hydraulic control module, lighting system, and sensors. Afterwards, the connection is made via the main line... The main harness 1 enables the functional transmission of the line, distributing the power and signals transmitted by the main harness 1 to the corresponding conductors. Next, the operator rotates the protective cover 5 using the hinges 4 on both sides of the top rear of the lower mounting housing 21, so that the protective cover 5 covers the top of the lower mounting housing 21, preventing external dust, mud, rainwater, oil and other impurities from entering the connection between the connecting mechanism 2 and the integration mechanism 3. Finally, when the line needs maintenance, the operator rotates the protective cover 5 to open it. At this time, the operator presses the pressing rod 24. Since the pressing rod 24 slides in the sliding hole 23, the pressing action will cause the pressing rod 24 to move vertically downward along the sliding hole 23. Its bottom contacts the lower pressure plate 34 and applies pressure. After the lower pressure plate 34 is subjected to force, it compresses the return spring 33 fixed in the mounting hole 32 at the top of the connector 31, so that the return spring 33 is in a contracted state. At this time, the locking limit of the connector 31 is released, and the operator can easily remove the connector 31. After the operator completes the maintenance work, the connector 31 can be inserted back into the connecting housing 22.

[0038] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
