Description

Technical Field

[0001] This utility model relates to the field of vehicle wiring harness technology, specifically to a high-voltage wiring harness protective bracket for non-road mining trucks. Background Technology

[0002] Fuel-powered mining trucks play an indispensable role in ore extraction and transportation in mining areas. However, the operating environment in mining areas is often extremely harsh, including but not limited to muddy and slippery roads, dust storms, and frequent heavy-duty operations. Under such conditions, fuel-powered mining trucks not only need to withstand high levels of physical wear and tear but also need to cope with complex and ever-changing operating conditions.

[0003] Among them, the high-voltage wiring harness is an important component of the power transmission and control system of fuel-powered mining trucks, and its operating status directly affects the performance and safety of the entire vehicle. Due to the special environment of mining areas, the high-voltage wiring harness is easily covered by mud, dust and other contaminants during long-term, uninterrupted operation of the vehicle. This increases the weight of the wiring harness itself, increases the load on the vehicle, and can gradually seep into the plugs or terminal connections inside the wiring harness, leading to problems such as poor contact or short circuits.

[0004] If the plugs or terminals of the high-voltage wiring harness fail due to poor contact, it will directly affect the vehicle's power supply system, leading to insufficient engine power or even failure to start the vehicle. Simultaneously, the stability of the communication system will be severely threatened, potentially causing data transmission interruptions and inability to execute control commands, thus impacting the overall efficiency and safety of mining operations. Therefore, effectively addressing the protection of high-voltage wiring harnesses in the harsh environment of mining areas has become an urgent problem to be solved in the current use of fuel-powered mining trucks. Utility Model Content

[0005] The purpose of this invention is to provide a protective bracket for high-voltage wiring harnesses in non-road mining trucks, which solves the technical problem of how to protect the high-voltage wiring harnesses of mining trucks in the harsh environment of mining areas.

[0007] Main framework, including

[0008] A concave plate includes a base plate and two side plates. The base plate is horizontally arranged, and the two side plates are respectively located on both sides of the base plate. One of the side plates has a wire-passing hole.

[0009] Two mating plates are respectively disposed at the rear end of the side plate and perpendicular to the side plate, and are provided with a plurality of spaced first through holes.

[0010] A front baffle is detachably installed at the front end of the concave plate to close the front opening of the concave plate.

[0011] This application uses a main frame and front baffle to shield exposed wiring harnesses, preventing them from being exposed to the external environment, reducing the probability of wiring harness failure, improving the stability of wiring harness use, and enhancing the overall vehicle's electrical safety. The application also creates space for wiring by creating wiring holes, ensuring normal wiring routing without interference with the bracket and guaranteeing connection stability. Furthermore, the application uses a mating plate to improve the bracket's installation stability, and the front baffle is a detachable component, facilitating maintenance and wiring harness replacement, improving operational convenience and maintenance efficiency.

This solution allows the first and second vertical bars, as well as the first and second ear plates, to be bolted together, resulting in a highly stable connection that is easy to assemble and disassemble. The structure is also simple and easy to manufacture.

[0023] Preferably, both the first through hole and the fourth through hole are vertically arranged elongated holes; this design allows for a certain offset, enabling fine-tuning of the component assembly, avoiding situations where installation is impossible due to minor positional deviations, and reducing installation complexity.

[0024] Preferably, the two mating plates are on the same horizontal plane, with one located inside the concave plate and the other outside the concave plate. This solution shortens the overall width of the protective bracket, reduces the space occupied, improves the structural compactness, thereby freeing up space for the arrangement of other components, saving material usage, and reducing manufacturing costs.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0040] To better understand the above technical solutions, the following will provide a detailed description of the technical solutions in conjunction with the accompanying drawings and specific embodiments.

[0041] Example:

[0042] like Figure 1 and Figure 2 As shown in the figure, this application discloses a high-voltage wire harness protection bracket for non-road mining trucks, which is used to protect the exposed parts of the high-voltage wire harness at the motor output line. Specifically, it includes: a main frame 1 and a front baffle 2.

[0043] The main frame 1 includes a concave plate 11 and two mating plates 12, which are configured as follows:

[0044] The concave plate 11 is used to wrap and protect the bottom and sides of the high voltage wire harness, including a bottom plate 111 and two side plates 112. The bottom plate 111 is arranged horizontally, and the two side plates 112 are respectively located on both sides of the bottom plate 111. A wire hole 1121 is provided on one side plate 112, which allows the wire harness to enter the inner side of the protective bracket from the outside.

[0045] Two docking plates 12 are respectively located at the rear end of the side plate 112 and perpendicular to the side plate 112. They are used for installation and fixation with the rear end of the motor. Multiple spaced first through holes 121 are provided to facilitate the use of bolts or other fasteners to securely install the protective bracket onto the mine car, thereby enhancing the overall stability and reliability.

[0046] The front baffle 2 is detachably installed at the front end of the concave plate 11 to close the front opening of the concave plate 11. It not only effectively prevents dirt, dust and other impurities from entering from the front end and protects the high-voltage wire harness from damage by the external environment, but also facilitates the maintenance and replacement of the wire harness, improving the convenience of operation and maintenance efficiency.

[0047] The above technical solution is used as follows:

[0048] During installation, the two mating plates 12 are attached to the fixed areas on both sides of the rear end of the motor. Then, the first through hole 121 is aligned with the bolt holes in the fixed area and bolted together. This allows the main frame 1 to be securely installed. The concave plate 11 protects the bottom and sides of the exposed part of the wire harness at the motor output line through the bottom plate 111 and the side plate 112. Then, the front baffle 2 is detachably installed at the front end of the concave plate 11 to protect the front end of the exposed part and facilitate the maintenance and replacement of the wire harness. At the same time, the wire harness can enter the protective bracket from the outside through the wire hole 1121.

[0049] This utility model uses a main frame 1 and a front baffle 2 to shield the exposed parts of the wiring harness, preventing it from being exposed to the external environment, reducing the probability of wiring harness failure, improving the stability of the wiring harness, and enhancing the overall vehicle's electrical safety. The wire routing holes 1121 create space for wiring, ensuring normal wiring routing without interference with the bracket and guaranteeing connection stability. The mating plate 12 further improves the bracket's installation stability. The front baffle 2 is a detachable component, facilitating maintenance and wiring harness replacement, improving operational convenience and maintenance efficiency. Furthermore, the structure is simple and compact, making it easy to manufacture.

[0050] In some embodiments, as Figure 3 As shown, the front baffle 2 is an integrally formed part, including a middle plate 21, a first vertical strip 22 and a first ear plate 23; wherein, the middle plate 21 is adapted to the front opening of the concave plate 11, the first vertical strip 22 is provided on one side of the middle plate 21, and the first ear plate 23 is provided on the other side of the middle plate 21.

[0051] In this embodiment, the main frame 1 includes a second vertical bar 13 and a second ear plate 14; wherein, the second vertical bar 13 is disposed on the outer side of the front end of a side plate 112, and the second ear plate 14 is disposed on the outer side of the front end of another side plate 112.

[0052] The first vertical bar 22 and the second vertical bar 13 correspond to each other and are detachably connected, and the first ear plate 23 and the second ear plate 14 correspond to each other and are detachably connected.

[0053] The above settings increase the area of ​​the mating surfaces of the main frame 1 and the front baffle 2, thereby improving the stability of their connection.

[0054] Based on the above embodiments, such as Figures 1-3 As shown, the first vertical bar 22 has multiple second through holes 221, and the second vertical bar 13 has multiple third through holes 131, with the second through holes 221 and the third through holes 131 corresponding one-to-one;

[0055] The first ear plate 23 has a fourth through hole 231, and the second ear plate 14 has a fifth through hole 141, with the fourth through hole 231 and the fifth through hole 141 corresponding to each other.

[0056] For example, both the second through hole 221 and the third through hole 131 are provided as two, and are spaced apart vertically, but this is not limited to this and is not restricted.

[0057] With the above configuration, the first vertical bar 22 and the second vertical bar 13, as well as the first ear plate 23 and the second ear plate 14, can be bolted together. The connection is highly stable, easy to disassemble and assemble, and has a simple structure that is easy to manufacture.

[0058] In this embodiment, if Figure 2 and Figure 3 As shown, both the first through hole 121 and the fourth through hole 231 are vertically arranged elongated holes.

[0059] With the above settings, a certain offset is provided, which enables the component assembly to have a fine-tuning function, avoiding the situation where installation is impossible due to slight positional deviations, and reducing the complexity of installation.

[0060] In some embodiments, such as Figure 2 As shown, the two mating plates 12 are on the same horizontal plane, with one located inside the concave plate 11 and the other located outside the concave plate 11.

[0061] The above design shortens the overall width of the protective bracket, reduces the space occupied, and improves the structural compactness, thereby freeing up space for the arrangement of other components, saving material usage, and reducing manufacturing costs.

[0062] In some embodiments, such as Figure 1 and Figure 2 As shown, the wire through hole 1121 is arranged on the front side of the bottom end of the side plate 112; it can reduce the degree of bending of the wire harness, reduce the damage of bending stress to the wire harness, improve the performance of the wire harness, and extend its service life.

[0063] In some embodiments, such as Figure 1 and Figure 2 As shown, the top of a side panel 112 has a raised section 1122.

[0064] It should be noted that since the top of the side plate 112 on the outer side of the motor does not have a baffle, the protective effect can be improved by setting an extension section 1122 on the side plate 112, which enhances the blocking effect against external mud, dust and other pollutants.

[0065] Numerous specific details are set forth in this specification. However, it will be understood that embodiments of this invention may be practiced without these specific details. In some instances, well-known methods, structures, and techniques have not been shown in detail so as not to obscure the understanding of this specification.
