[0054] Now, exemplary embodiments according to the present application will be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments may be implemented in a variety of different forms and should not be construed as being limited to the embodiments described herein. It should be understood that these embodiments are provided to make the disclosure of the present application thorough and complete, and to fully convey the concepts of these exemplary embodiments to those of ordinary skill in the art. In the accompanying drawings, for the sake of clarity, the thickness of the layers and regions may be enlarged, and the same reference numerals are used to represent the same devices, and thus their descriptions will be omitted.

[0055] like Figure 1 As shown, Figure 1 In the prior art trailer wiring harness installation structure, the wiring harness fixing assembly is fixed on the longitudinal beam by a clamp or a bracket, which occupies the longitudinal beam space, causing inconvenience in operation and maintenance, and reduced safety in the installation of the trailer wiring harness.

[0056] Combination Figures 2 to 8 As shown, according to a specific embodiment of the present application, a trailer wiring harness installation device is provided.

[0057] Specifically, the trailer wiring harness installation device includes a rear suspension bracket 1 and a wiring harness fixing assembly 2. There are two rear suspension brackets 1, one of which is connected to one of the longitudinal beams 6, and the other rear suspension bracket 1 is connected to the other longitudinal beam 6. The two rear suspension brackets 1 are both arranged close to the cab; the wiring harness fixing assembly 2 is used to fix and install the wiring harness, and mounting seats 3 are provided at both ends of the wiring harness fixing assembly 2. The wiring harness fixing assembly 2 is connected to the rear suspension bracket 1 through the mounting seat 3.

[0058] By applying the technical solution of this embodiment, a wire harness fixing assembly 2 is arranged on the rear suspension bracket 1 behind the cab. The wire harness fixing assembly 2 is directly arranged on the rear suspension bracket 1 through the mounting seat 3, thereby avoiding setting the wire harness fixing assembly 2 on the longitudinal beam 6 and occupying the space of the vehicle longitudinal beam 6 and the vehicle chassis.

[0059] In this embodiment, the rear suspension bracket 1 is used as a fixed point to avoid space encroachment and layout conflicts that may be caused by direct connection of the wiring harness installation structure with the longitudinal beam 6 or the chassis, thereby ensuring the stability of the wiring harness installation and the rationality of the layout of the vehicle chassis, improving the efficiency and safety of the wiring harness installation, and optimizing the chassis space layout, thereby enhancing the flexibility of vehicle design and overall performance.

[0060] Specifically, Figures 3 to 5 As shown, the mounting seat 3 includes a terminal 31 and a connecting bracket 32, wherein the terminal 31 is connected to the harness fixing assembly 2, and the terminal 31 has a first connecting structure 312; the connecting bracket 32 ​​is connected to the rear suspension bracket 1, and the connecting bracket 32 ​​has a second connecting structure 321; wherein the first connecting structure 312 and the second connecting structure 321 cooperate with each other to connect the terminal 31 with the connecting bracket 32. Through the cooperation between the first connecting structure 312 and the second connecting structure 321, it can be ensured that the connection between the terminal 31 and the connecting bracket 32 ​​is more stable and reliable, and the loose connection caused by vibration or harsh environment during the driving of the vehicle can be avoided, thereby improving the overall stability of the connection between the harness fixing assembly 2 and the rear suspension bracket 1. At the same time, the use of the first connecting structure 312 and the second connecting structure 321 that can cooperate can greatly simplify the installation and removal process of the harness fixing assembly 2. Without complex welding equipment and professional skills, the harness fixing assembly 2 can be quickly installed or removed, which improves work efficiency and reduces maintenance costs.

[0061] Furthermore, if Figure 3 , Figure 4 As shown, both ends of the harness fixing assembly 2 are tubular structures, and the end 31 includes a sleeve 311, and a plurality of first connection structures 312 are arranged on the outer wall of the sleeve; wherein, when the tubular structure is connected with the sleeve 311, the tubular structure extends into the sleeve 311. The cooperation between the tubular structure and the sleeve 311 forms a sleeve-like structure by extending the tubular structure into the sleeve 311, which increases the cross-sectional area of ​​the connection area, thereby improving the strength and stability of the overall structure, ensuring that the harness is not easily displaced or damaged under various road conditions, and the connection method between the tubular structure and the sleeve 311 is usually simpler and faster than welding, and can be relatively easy to operate methods such as plug-in, threaded connection, and crimping, thereby reducing assembly time and cost. A plurality of first connection structures 312 (such as protrusions, threads, snaps, etc.) are arranged on the outer wall of the sleeve 311, which can form multi-point contact or fixation with the second connection structure 321 of the connecting bracket 32. This multi-point connection method is more reliable than a single-point connection, and can effectively disperse the load and reduce the risk of failure of the entire connection structure due to a single-point failure.

[0062] Furthermore, if Figure 5As shown, the connecting bracket 32 ​​includes a bracket body and a second connecting structure 321 arranged on the bracket body. A connecting hole 320 is also provided on the bracket body, and the bracket body is connected to the rear suspension bracket 1 through the connecting hole 320. The connecting bracket 32 ​​can be connected through the connecting holes 320 by bolts, pins or other connecting parts passing through these holes and aligned with the corresponding holes of the rear suspension bracket 1, and the two are firmly fixed together by fasteners. This connection method is more stable, and the fasteners provide a balanced force distribution, reducing the risk of fracture or damage of the connection point due to local stress concentration. By inserting the fasteners into the connecting holes 320, the connecting bracket 32 ​​can be quickly and accurately fixed to the rear suspension bracket 1, without the need for complex welding operations, simplifying the assembly process and reducing the difficulty of operation.

[0063] In this embodiment, since the connecting bracket 32 ​​is connected to the rear suspension bracket 1 using the connecting hole 320 and the fastener, the connecting bracket 32 ​​can be directly integrated into a shape that matches the rear suspension bracket 1, which facilitates the fastening connection between the connecting bracket 32 ​​and the rear suspension bracket 1, and through the cooperation of the connecting hole 320 and the fastener, the connecting bracket 32 ​​can be easily installed on the rear suspension bracket 1, which is convenient for subsequent maintenance inspection or replacement operations without destroying the original structure, thereby improving maintenance efficiency and reducing maintenance costs.

[0064] Specifically, the bracket body has a accommodating space. When the connecting bracket 32 ​​is connected to the terminal 31, at least part of the terminal 31 is located in the accommodating space, and the second connecting structure 321 is arranged on the side wall of the accommodating space. The terminal 31 is partially located in the accommodating space of the connecting bracket 32, which can form a nested connection. This connection method can increase the contact area of ​​the connection, thereby improving the stability and reliability of the overall structure. When the nested structure is subjected to external force, it can distribute stress more evenly and reduce the possibility of single point failure. At the same time, the design of the accommodating space allows the terminal 31 to be partially hidden, reducing the external occupied space, avoiding interference with other chassis components, helping to optimize the chassis layout, and providing more installation space for other key components. The second connecting structure 321 is arranged on the side wall of the accommodating space, which can cooperate with the first connecting structure 312 of the terminal 31 to form a closed connection, which helps to improve the waterproof and dustproof performance of the connection part. This design makes the connection part more concealed and neat, improves the appearance of the vehicle chassis, and enhances the visual effect and customer perception of the whole vehicle.

[0065] Further, the first connection structure 312 includes a first connection hole 3120 opened on the outer wall of the pipe sleeve 311, and the second connection structure 321 includes a second connection hole 3210 opened on the side wall of the accommodation space. When the terminal 31 cooperates with the bracket body, the first connection hole 3120 and the second connection hole 3210 are arranged correspondingly. The corresponding arrangement of the first connection hole 3120 and the second connection hole 3210 ensures that the terminal 31 and the connecting bracket 32 ​​can be accurately aligned during assembly. By inserting fasteners such as bolts and pins through these corresponding holes, a firm fixation can be achieved, and the stability of the connection can be maintained even if the vehicle is subjected to vibration and impact during driving. The corresponding connection hole design makes the assembly process simple and intuitive. The operator only needs to embed the pipe sleeve 311 of the terminal 31 into the accommodation space of the bracket body, ensure that the first connection hole 3120 is aligned with the second connection hole 3210, and then use fasteners to connect, without the need for complex positioning or adjustment, thereby improving assembly efficiency.

[0066] Furthermore, if Figure 5 As shown, the connecting bracket 32 ​​also includes a trailer valve mounting portion 322 disposed on the bracket body, and the trailer valve mounting portion 322 is used to install the trailer valve. The trailer valve mounting portion 322 is integrated on the bracket body, making full use of the space of the connecting bracket 32, avoiding the need to find or design an additional fixing position for the trailer valve on the vehicle chassis, optimizing the chassis layout, providing more installation space for other components, and contributing to the compactness and efficiency of the overall vehicle design. The trailer valve is directly mounted on the trailer valve mounting portion 322 on the connecting bracket 32, which simplifies the assembly process and reduces the independent connection points between the trailer valve and the vehicle, which means that during the assembly and maintenance process, the operator can complete the installation and removal of the trailer valve more quickly and conveniently, reducing maintenance costs and time.

[0067] Furthermore, if Figure 2 , Figure 7As shown, the trailer harness installation structure also includes a pedal assembly 4, which is arranged on one side of the longitudinal beam 6 and connected to the longitudinal beam 6. The pedal assembly 4 has a plurality of foot pedals 41, and the plurality of foot pedals 41 are arranged at intervals along the height direction of the longitudinal beam 6. The arrangement of the plurality of foot pedals 41 provides the technicians with operating platforms at multiple heights, so that when installing, maintaining or inspecting the trailer harness, no additional auxiliary tools are required, and the pedal assembly 4 is directly arranged on the longitudinal beam 6, which not only makes full use of the existing structure of the vehicle, but also avoids occupying additional chassis space. This design makes the entire trailer harness installation structure more compact, helps to optimize the layout of the vehicle chassis, and provides more installation space for other components. The integrated design of the pedal assembly 4 reduces the demand for an independent support structure, reduces production costs and assembly complexity, and the design of the pedal assembly 4 integrated with the longitudinal beam 6 makes the entire vehicle chassis look neater and more professional, avoids the visual clutter that may be caused by the exposed pedal assembly 4, and enhances the customer's positive perception of the vehicle design and manufacturing quality.

[0068] Specifically, Figure 7 As shown, the pedal assembly 4 includes two support brackets 42, one end of the support bracket 42 is connected to the longitudinal beam 6, and the two support brackets 42 are arranged at a distance. The foot pedal 41 is arranged between the two support brackets 42, one end of the foot pedal 41 is connected to one of the support brackets 42, and the other end of the foot pedal 41 is connected to the other support bracket 42. The two support brackets 42 are respectively connected to the longitudinal beam 6 and are arranged parallel to the ground at a certain distance, providing a wider support foundation, thereby enhancing the stability of the entire pedal assembly 4. When using the foot pedal 41, the operator can feel a more stable support, reducing the risk of shaking or tilting, and ensuring a safe working environment. The foot pedal 41 is arranged between the two support brackets 42, and the two ends are respectively connected to the two support brackets. Such a layout ensures that the foot pedal is firmly fixed in the longitudinal beam height direction, and even when carrying heavy objects or being impacted, it can maintain its position stable and is not easy to deform or damage. The connection between the two support brackets 42 and the longitudinal beam 6, as well as the layout of the foot pedal 41, are completed without occupying additional space. This design enables the pedal assembly 4 to fit closely to the longitudinal beam 6, reduces interference with other components of the vehicle chassis, and optimizes the chassis space layout.

[0069] Furthermore, if Figure 2As shown, the trailer wiring harness installation device also includes a first support plate 51, which is arranged on the longitudinal beam 6. By arranging the first support plate 51 on the longitudinal beam 6, a more direct and convenient access point is provided for technicians to perform daily inspection and maintenance of the wiring harness. Maintenance personnel can stand on the first support plate 51 to access the wiring harness more safely and conveniently, reducing the complexity and time of maintenance operations. Using the first support plate 51 as a support structure has lower production costs and a simpler and faster installation process than complex custom brackets.

[0070] In this embodiment, a pad is provided between the first support plate 51 and the longitudinal beam 6. The pad is made of a rubber material with high elasticity and tolerance and in contact with the longitudinal beam, which can effectively absorb the vibration and impact generated by the vehicle's running, reduce the impact of these adverse factors on the wiring harness and the supporting structure, and reduce noise transmission, thereby improving the vehicle's driving comfort and the stability of the wiring harness system. The provision of the pad avoids direct contact between the first support plate 51 and the metal surface of the longitudinal beam 6, reduces the risk of electrochemical corrosion, extends the service life of the support plate and the longitudinal beam, and maintains the integrity of the vehicle chassis. At the same time, the rubber pad can prevent the support plate from scratching or indenting the surface of the longitudinal beam during installation or use, maintain the appearance quality and structural integrity of the longitudinal beam, and avoid stress concentration and potential structural problems caused by surface damage. Preferably, the rubber material is EPDM rubber.

[0071] Specifically, Figure 8 As shown, the first support plate 51 is detachably connected to the longitudinal beam 6 via a limiting clip 53 .

[0072] In an exemplary embodiment of the present application, the limit clip 53 is made of a steel plate structure as a whole. The limit clip 53 includes a contact end connected to the longitudinal beam 6, a connecting end and a limit end. The contact end is adhered with a rubber material of the same material as the pad. Through its high elasticity and friction coefficient, it forms a close contact with the inner wing surface of the frame longitudinal beam 6 to achieve a limit effect. The use of rubber material also helps to protect the inner wing surface of the longitudinal beam 6, avoid wear, scratches or electrochemical corrosion caused by direct metal contact, extend the service life of the longitudinal beam 6, and maintain its structural integrity. The limit end is used to contact the elliptical groove on the first support plate 51 to form precise positioning and limiting, ensure the stable installation of the working platform on the vehicle, prevent shaking or displacement during the driving of the vehicle, and improve the safety of the operator and the convenience of operation. The connecting end is welded with a nut on the lower side of the hole, so that the limit clip 53 can be detachably fixedly connected to the elliptical groove of the first support plate 51 by bolts. This connection method not only ensures the reliability of the connection, but also provides a convenient installation and maintenance method, which is convenient for regular inspection and adjustment.

[0073] Furthermore, if Figure 2 , Figure 7As shown, the support bracket 42 includes a first support section 421 and a second support section 422, the first support section 421 and the second support section 422 are connected at an angle, the first support section 421 is connected to the longitudinal beam 6, a footrest 41 is arranged between the two second support sections 422, and the second support section 422 is connected to the footrest 41, wherein a second support plate 52 is arranged on the first support section 421, and the upper end surface of the second support plate 52 is arranged flush with the upper end surface of the longitudinal beam 6. The first support section 421 and the second support section 422 are connected at a certain angle, such a design can form a stable triangular support structure between the longitudinal beam 6 and the footrest 41, increase the stability of the support, and effectively resist the force generated by vibration or impact when the vehicle is running, ensuring the stability of the footrest 41 and the entire pedal assembly 4. The first support section 421 is connected to the longitudinal beam 6, and the two second support sections 422 form the support basis of the foot pedal 41, which can make full use of the chassis space and take into account the stepping comfort and safety of the operators. The connection point between the second support section 422 and the foot pedal 41 provides a stable support point for stepping, reduces the shaking feeling when stepping, and improves the user experience.

[0074] According to another specific embodiment of the present application, a vehicle is provided, the vehicle having a trailer wiring harness installation device, the trailer wiring harness installation device being the trailer wiring harness installation device in the above embodiment. The vehicle as a whole integrates the wiring harness fixing assembly 2, the pedal assembly 4, the first support plate 51, and the second support plate 52 on the frame longitudinal beam 6, so as to realize the rapid installation and removal of the wiring harness, optimize the spatial layout of the vehicle chassis, improve the efficiency and safety of the wiring harness installation, and enhance the flexibility and overall performance of the vehicle design.

[0075] The present application also provides a preferred embodiment of a trailer wiring harness installation device. By not directly connecting the wiring harness installation structure to the chassis, the encroachment on the chassis layout space is avoided, and more ample installation space is provided for other chassis components, which is beneficial to the optimization of the overall layout of the vehicle and improves the flexibility and efficiency of vehicle design.

[0076] Specifically, the trailer harness installation device includes a harness fixing assembly 2, a first support plate 51, a second support plate 52, and a pedal assembly 4, which are mainly used to fix the trailer harness and facilitate the installation of the trailer harness. The harness fixing assembly 2 is used to provide an installation position for the trailer harness. It is integrally fixed to the rear suspension bracket 1 of the cab through a casting and forging. It is located above the longitudinal beam 6 and is not connected to the longitudinal beam. It does not occupy the longitudinal beam 6 and the chassis layout space. It has few part variants, a high degree of modularization, and a safe and reliable connection. The first support plate 51, the second support plate 52, and the pedal assembly 4 are used for pedaling when installing the trailer harness. They fully cover from the middle of the longitudinal beam 6 to the side, have a safe and reliable connection, are convenient for pedaling, and have a good appearance of the vehicle and customer perception.

[0077] The wiring harness fixing assembly 2 includes a mounting plate, a tube beam, an end cap 31 and a connecting bracket 32. The mounting plate is welded and fixed on the tube beam, and a mounting hole is provided on the end cap for fixing the trailer wiring harness. The tube beam is a U-beam structure; the end cap 31 is a forged part (integrally forged). The end cap 31 includes a pipe sleeve 311 and a first connecting structure 312. The pipe sleeve 311 is connected to the pipe pins at both ends of the tube beam by welding or screwing. The first connecting structure 312 is connected and fixed to the connecting bracket 32 ​​by a brush assembly; the connecting bracket 32 ​​is integrally forged into a half-box shape. The connecting bracket 32 ​​includes a connecting hole 320, a second connecting structure 321 and a trailer valve mounting portion 322. The connecting hole 320 is used to be fixedly connected to the rear suspension bracket 1 of the cab. The second connecting structure 321 is used to be connected to the first connecting structure 312 by a bolt assembly to complete the fixation of the trailer wiring harness mounting device. The trailer valve mounting portion 322 is used to reserve a mounting hole position for the trailer valve.

[0078] The first support plate 51 is fixed on the frame longitudinal beam 6 as a whole, and the first support plate 51 is connected to the longitudinal beam 6 through a pad and a limit clip 53.
