Description

Technical Field

[0001] This invention relates to the field of natural gas commercial vehicle chassis technology, and more particularly to a wiring harness installation structure for a natural gas commercial vehicle trailer. Background Technology

[0002] As natural gas prices gradually decrease, the advantages of natural gas tractor units in reducing transportation costs are becoming increasingly apparent. To further reduce transportation costs, a mother-daughter vehicle transportation model is typically used for natural gas transfer. This model operates as follows: on the outbound journey when fully loaded, the mother vehicle and daughter vehicle work together to complete the transportation task; on the return journey when empty, the mother vehicle carries the daughter vehicle for relocation operations.

[0003] In practice, to meet the loading requirements of the mother car for the trailer, the front of the trailer is moved forward as far as possible to the rear of the trailer cab, thus shortening the overall length of the trailer train. Traditionally, the brake air circuits, wiring harnesses, and other trailer pipelines between the trailer and the trailer are connected using standard trailer sockets. These connection points are generally fixed at the rear of the natural gas cylinder frame. However, this traditional installation method has significant drawbacks. Specifically, when the trailer is moved to its extreme forward position, the trailer portion is highly susceptible to collision, compression, or scraping with the loose trailer pipelines and their connectors, posing a high risk of interference. Long-term operation can lead to wear and tear on the pipelines, potentially causing safety hazards or functional malfunctions. Furthermore, to avoid interference between the trailer and the pipelines and connectors during forward movement, the front overhang of the trailer often needs to be shortened. This directly limits the effective length of the trailer, thus reducing the cargo capacity per trip, resulting in poor versatility and impacting overall transportation efficiency.

[0004] Therefore, there is an urgent need for a natural gas commercial vehicle trailer wiring harness installation structure to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a natural gas commercial vehicle trailer wiring harness installation structure that can effectively avoid interference between the trailer wiring harness and the vehicle when the trailer moves forward, thereby improving its versatility and reliability.

[0032] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0033] like Figures 1 to 2As shown, this embodiment provides a natural gas commercial vehicle trailer wiring harness installation structure, which includes: a connecting plate 1, a first mounting plate 4, a second mounting plate 6, and a wiring harness handle bracket 7. The connecting plate 1 is connected between the gas cylinder frame 2 and the vehicle frame 3. The first mounting plate 4 is integrated on the connecting plate 1 and has multiple mounting holes for fixing the trailer wiring harness connector 5. The second mounting plate 6 is integrated on the gas cylinder frame 2, and the wiring harness handle bracket 7 is integrated on one side of the second mounting plate 6. This configuration integrates the connecting plate 1 with the first mounting plate 4, adaptively adjusting the installation position of the trailer wiring harness connector 5 to move it forward, reducing the space occupied at the rear and completely avoiding contact between the trailer wiring harness connector 5 and the trailer. This provides ample, unobstructed physical space for the trailer to move forward, effectively preventing positional interference between the trailer and the wiring harness when the trailer moves forward. It fundamentally eliminates potential risks caused by collisions, squeezing, or scratches, effectively protecting the brake air circuit and electrical wiring harness, preventing brake failure or electrical faults caused by pipeline damage, greatly improving the safety and reliability of dual-vehicle transport, and providing more possibilities for the selection of trailers, thus improving its overall versatility and reliability.

[0034] It should be noted that when designing the multiple mounting holes on the first mounting plate 4, it is necessary to make reasonable plans based on the actual number and external dimensions of the trailer wiring harness connectors 5 required, so as to ensure that the number of mounting holes corresponds one-to-one with the trailer wiring harness connectors 5, and that the size and shape of the holes can fully adapt to the installation requirements of the trailer wiring harness connectors 5. At the same time, it is also necessary to consider the reasonable spacing between the trailer wiring harness connectors 5 to avoid mutual interference, so as to ensure the stability, reliability and overall layout of the wiring harness connection.

[0035] In this embodiment, the natural gas commercial vehicle trailer wiring harness installation structure also includes several first connectors, all of which are connected between the gas cylinder frame 2 and the connecting plate 1.

[0036] Optionally, the wiring harness installation structure for the natural gas commercial vehicle trailer also includes several second connectors, all of which are connected between the frame 3 and the connecting plate 1.

[0037] Optionally, the wiring harness installation structure for natural gas commercial vehicle trailers also includes several third connectors, all of which are connected between the connecting plate 1 and the first mounting plate 4.

[0038] Furthermore, the first, second, and third connecting parts are all bolts. This configuration ensures the overall structural strength and stability while enabling convenient installation, disassembly, and maintenance of components. Through the use of bolts and nuts, the gas cylinder frame 2 and connecting plate 1, the vehicle frame 3 and connecting plate 1, and the connecting plate 1 and first mounting plate 4 are firmly connected in pairs. At the same time, it retains the characteristic of being able to be separated without damaging the components when needed. This significantly reduces the cost and difficulty of subsequent maintenance and replacement of parts, and facilitates modular design and assembly of components or structures, improving the flexibility and adaptability of the overall system.

[0039] In this embodiment, the first mounting plate 4 includes a connecting part and a mounting part. The connecting part is fixedly connected to the mounting part, and multiple mounting holes are provided in the mounting part. The connecting part is fixedly mounted to the connecting plate 1, and the connecting part and the mounting part are arranged perpendicular to each other. With this arrangement, the mounting part can be optimally designed according to the specific number, shape, and layout of the trailer wiring harness connectors 5, without being constrained by the structural limitations of the connection. The connecting part can be adapted to the available space and optimal stress point of the connecting plate 1, further improving space utilization, avoiding positional interference, effectively enhancing the design freedom and adaptability of the components, and optimizing the stress distribution, thereby improving the structural reliability and durability of the entire wiring harness fixing point.

[0040] Optionally, the tube bundle grip bracket 7 includes a main body 71, a first mounting ear 72, and a second mounting ear 73. The first mounting ear 72 and the second mounting ear 73 protrude from both ends of the main body 71, and both the first mounting ear 72 and the second mounting ear 73 are fixedly mounted to the side wall of the second mounting plate 6. This arrangement fixes the tube bundle grip bracket 7 to the side, further reducing the space occupied at the rear, moving the position of the trailer tube bundle forward, effectively avoiding interference between the air pipes and components such as the trailer, axle, etc., optimizing the air path, shortening the air path length, improving space utilization, and potentially reducing pipe losses.

[0041] In this embodiment, the natural gas commercial vehicle trailer wiring harness installation structure further includes a first mounting component and a second mounting component. The first mounting component is fixedly connected between the first mounting ear 72 and the second mounting plate 6, and the second mounting component is fixedly connected between the second mounting ear 73 and the second mounting plate 6. Of course, in other embodiments, to improve the overall connection stability and reliability of the structure, the first mounting ear 72 and the second mounting ear 73 can be integrally formed with the second mounting plate 6 by welding. This effectively resists vibration and impact during vehicle transportation, ensuring the long-term stability of the wiring harness handle bracket 7 and the gas pipe it supports, thus improving the system's durability and safety.

[0042] Optionally, the main body 71 is U-shaped.

[0043] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
