Description

Technical Field

[0001] This invention relates to the field of commercial vehicle manufacturing technology, and in particular to an integrated electrical component and a commercial vehicle. Background Technology

[0002] In the field of commercial vehicle technology, a large number of electrical components are required, such as wiring harness connectors. These connectors are usually installed in the chassis or cab of a commercial vehicle. However, in actual installation, there are many connectors, and different wiring harnesses need to be connected to different connectors. The connectors need to be connected to the corresponding brackets first, and then the brackets are installed in the chassis or cab. A large number of brackets will increase the weight of the commercial vehicle.

[0003] The fasteners that connect the connector to the bracket are usually closer to the interior of the commercial vehicle. During installation, personnel need to use tools to pass through the wiring harness and connector to contact and tighten the fasteners deep inside. Due to the limited installation space, installation is difficult. During disassembly and maintenance, because the fasteners are located deep inside and the wiring harness also obstructs the tool's insertion space, it is necessary to pull out or disassemble the wiring harness before the connector can be removed from the bracket. Summary of the Invention

[0004] The purpose of this invention is to provide an integrated electrical component and a commercial vehicle, solving the problem of the high difficulty in the installation and disassembly of the plug-in connector in the prior art.

[0005] To achieve this objective, the present invention adopts the following technical solution: The present invention provides an integrated electrical component, including a main bracket, an auxiliary component, and a connector. The main bracket includes an ear plate and a main body. The ear plate is bent to the same side. An auxiliary component is connected to the end of the ear plate away from the main bracket. A fastener is installed on the side of the auxiliary component away from the main body. The fastener mounts the connector on the auxiliary component. The opening on the connector is located on the same side as the bending direction of the ear plate.

[0006] Preferably, the fastener includes a first bolt, and a first through hole is provided on the side of the ear plate away from the main body. The first bolt is screwed into the first through hole, and the auxiliary component is passed through the first bolt.

[0007] Preferably, the auxiliary component includes an auxiliary bracket with a mounting hole and a mounting screw inside the mounting hole, the mounting screw being screwed onto the connector.

[0008] Preferably, the ear plate is bent to form a first connecting plate on the side away from the main support, and the end of the auxiliary support is bent to form a second connecting plate. The first connecting plate and the second connecting plate are connected by the first bolt.

[0009] Preferably, at least one set of auxiliary supports is installed on the first connecting plate.

[0010] Preferably, at least one set of auxiliary supports is installed on the first bolt.

[0011] Preferably, one set of auxiliary brackets has a first pin hole, and the main bracket has a second pin hole, with rubber pins inserted into the first pin hole and the second pin hole in sequence.

[0012] Preferably, the ear plate comprises three sets, and the plug socket is installed between every two sets of ear plates.

[0013] Preferably, the main bracket has a connection hole, and the connection screw passes through the connection hole and is screwed onto the body of the commercial vehicle.

[0014] A commercial vehicle includes the integrated electrical components described in any of the preceding claims, wherein the main bracket is mounted on the chassis and driver's cab of the commercial vehicle.

[0015] Beneficial effects: Since the fastener is located on one side of the main body, during installation, the entire wire harness can be inserted into the connector, and then the fastener can be fixed by the worker using hand tools. Because the fastener is located on the outside, it is easy for the worker to position it with hand tools. At the same time, during disassembly, if it is necessary to replace the connector, the fastener on the corresponding auxiliary component can be removed directly to separate the fastener without disassembling unrelated parts to free up tool positioning space, thus reducing the difficulty of disassembly.

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0019] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0020] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0021] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0022] In the design and manufacturing of commercial vehicles, the integration and layout of electrical systems has always been a complex and critical task. With the continuous improvement of vehicle electrification and intelligence, the types and number of on-board electrical components have increased significantly, covering multiple functional areas such as powertrain control, body electronics, safety systems, infotainment and remote monitoring. These electrical components need to be connected and transmit signals through a large number of wiring harnesses, and the connection between wiring harnesses generally relies on various plug-in sockets.

[0023] Currently, in the commercial vehicle sector, connectors are typically installed in the limited space inside the vehicle chassis or cab. Due to the complexity of the vehicle's electrical functions and the crisscrossing wiring harnesses, a large number of connectors are required. To reliably secure these connectors and prevent them from loosening or becoming loose due to vibrations or impacts during vehicle operation, specially designed brackets are used for support and positioning. Each connector often requires an independent mounting bracket, which is connected to the vehicle structure using fasteners such as bolts and screws. As the number of electrical components continues to increase, the number of brackets also increases. Each bracket itself has a certain weight, and the accumulation of a large number of brackets increases the curb weight of the commercial vehicle.

[0024] In addition to the aforementioned weight issues, the practical difficulties encountered during the installation and maintenance of connectors are even more prominent. Due to the compact layout of vehicle structures, connectors are often located in areas close to the interior of the vehicle body. The fasteners that connect to the brackets are usually located on the side of the connector body facing the inside of the vehicle, that is, closer to adjacent components or body panels. When installing on the assembly line, operators need to align the connector with the bracket mounting holes and then use tools such as screwdrivers and wrenches to pass through the pre-arranged wire harness bundles and the contour gaps of the connector itself to reach the fasteners located deep inside. Since the operating space is usually very narrow, it is difficult to align the tools vertically with the fasteners, and the construction angle is greatly limited. This is not only time-consuming and laborious, but also prone to incomplete tightening due to poor torque transmission, affecting the reliability of the connection.

[0025] During vehicle maintenance or troubleshooting after it has been put into operation, if a connector needs to be replaced or repaired, the maintenance personnel also need to first remove the fasteners that secure it to the bracket. However, after the vehicle is assembled, the wiring harness routing is basically fixed, and the connector is often surrounded by other wiring harnesses or components, creating visual and physical obstructions. At this time, the fasteners are located deeper and more concealed, making it difficult for tools to reach directly, and they are often blocked by the surrounding wiring harnesses, making it impossible to smoothly insert the bolts or screws. Maintenance personnel often have to laboriously move or pull out a portion of the wiring harness, or even temporarily disassemble adjacent components to make enough operating space. This process not only significantly extends maintenance time and increases labor costs, but may also accidentally damage the wire insulation or terminals during the movement of the wiring harness, causing malfunctions. In addition, frequent plugging and unplugging and movement will also accelerate the aging of the wiring harness and connector, affecting the long-term reliability.

[0026] In summary, the current installation and fixing methods of connectors in commercial vehicle electrical systems, while ensuring connection stability, also bring the dual challenges of increased vehicle weight and difficulties in installation, disassembly, and maintenance. How to optimize the fixing structure of connectors, reduce the use of additional brackets, and maximize the operability of installation and maintenance while ensuring safe and reliable electrical connections has become a practical issue that urgently needs to be addressed in the field of commercial vehicle electrical layout design.

[0027] To solve the above problems, such as Figures 1 to 3 As shown, the present invention provides an integrated electrical assembly, including a main bracket 1, an auxiliary component 2, and a connector 3. The main bracket 1 includes an ear plate 11 and a main body 12. The ear plate 11 is bent to the same side. The auxiliary component 2 is connected to the end of the ear plate 11 away from the main bracket 1. A fastener is installed on the side of the auxiliary component 2 away from the main body 12. The fastener installs the connector 3 on the auxiliary component 2. The opening on the connector 3 is on the same side as the bending direction of the ear plate 11. The main bracket 1 can be installed on the chassis of a commercial vehicle or inside the cab of a commercial vehicle as needed.

[0028] By connecting the auxiliary component 2 to the connector 3 on the side away from the main bracket 1, installation and subsequent maintenance are facilitated. Since the auxiliary component 2 is connected to the connector 3 via fasteners on the side away from the main body 12, the worker's tools will not be obstructed by the wiring harness on the connector 3 during subsequent installation and removal of the fasteners, reducing installation difficulty. At the same time, during disassembly, there is no need to disassemble the wiring harness or other parts. Because the position of the fasteners becomes more prominent, it is easier for workers to connect the tools to the fasteners. During the disassembly of the corresponding connector 3, there is no need to disassemble unrelated parts, reducing the difficulty for workers to connect the tools to the fasteners and improving maintenance efficiency. Since the main bracket 1 and the auxiliary component 2 are set separately, the weight and processing difficulty of individual parts can be reduced, making it more modular.

[0029] In this invention, the ear plate 11 of the main bracket 1 has a first through hole on the side away from the main body 12. The fastener includes a first bolt 4, which is screwed into the first through hole. An auxiliary component 2 is passed through the first bolt 4. The ear plate 11, which extends to the same side, can keep the fastener away from the main body 12 of the commercial vehicle, thus avoiding the fastener being buried deep under the wire harness. In the subsequent disassembly process, it is not necessary to pull out a large number of wire harnesses to establish a connection between the disassembly tool and the fastener. This invention uses the first bolt 4 to connect the auxiliary bracket 21 and the ear plate 11, which facilitates disassembly and replacement.

[0030] It should be noted that the connector 3 can be directly connected to the main support 1, or it can be connected to the main support 1 through the auxiliary component 2. If the connector 3 needs to be installed in the area between the ear plates 11, the connector 3 can be directly connected to the ear plates 11 and the main body 12. If the position of the connector 3 needs to be staggered from the position of the main support 1, that is, the height is inconsistent, the auxiliary support 21 needs to be used to change the installation position of the connector 3, and finally fix the connector 3 on the auxiliary support 21 to achieve the fixation of the connector 3. According to the design requirements, the installation position between the connector 3 and the main support 1 can be changed by using the auxiliary support 21.

[0031] Typically, the auxiliary component 2 is a plate-shaped structure that is bent into bent pieces at different angles through stamping. The installation position of the connector 3 can be changed by using different bent pieces. The auxiliary bracket 21 can be replaced as needed. When facing vehicles with different signals, the installation method of the connector 3 can be changed by replacing the auxiliary bracket 21, so that the integrated electrical components can be more flexibly applied to various scenarios.

[0032] The auxiliary component 2 includes an auxiliary bracket 21, which has mounting holes and mounting screws 211. The mounting screws 211 are screwed onto the connector 3. The auxiliary bracket 21 is directly connected to the connector 3. The mounting screws 211 are easy to disassemble. In the process of disassembling the integrated electrical components, the fasteners need to be removed first. The auxiliary bracket 21 can be separated from the connector 3 and the main bracket 1 at the same time. Then the mounting bolts on the auxiliary bracket 21 can be removed separately. Since the fasteners are located in a more obvious position, they are easy for workers to disassemble with hand tools.

[0033] The ear plate 11 is bent at the side away from the main support 1 to form a first connecting plate 111, and the auxiliary support 21 is bent at its end to form a second connecting plate 212. The first connecting plate 111 and the second connecting plate 212 are connected by a first bolt 4. The first connecting plate 111 and the second connecting plate 212 can fit together and are then fixed by the first bolt 4. Friction is generated between the first connecting plate 111 and the second connecting plate 212, thereby achieving the connection and fixation effect of the first connecting plate 111 and the second connecting plate 212. The first connecting plate 111 and the second connecting plate 212 are usually bent at 90°, at which time the first connecting plate 111 and the second connecting plate 212 face the direction of disassembly and assembly for the worker to facilitate disassembly.

[0034] At least one set of auxiliary brackets 21 is installed on the first connecting plate 111. In this utility model, three sets of auxiliary brackets 21 are installed on the first connecting plate 111. The three sets of auxiliary brackets 21 are respectively for the plug-in sockets 3 at different positions on the main bracket 1, so that more plug-in sockets 3 can be installed on the main bracket 1. The auxiliary brackets 21 extend to different directions, so that the plug-in sockets 3 can be installed in an overlapping manner.

[0035] At least one set of auxiliary brackets 21 is installed on the first bolt 4. In order to accommodate more plug-in sockets 3, multiple sets of auxiliary brackets 21 can be fixed on the first bolt 4 at the same time, so that more auxiliary brackets 21 can be installed in the limited space on the first connecting plate 111, and the main bracket 1 of the present invention can install more plug-in sockets 3, thus making it more versatile.

[0036] First, this design greatly optimizes the spatial layout. In areas with limited installation space, such as commercial vehicle chassis or cabs, each connector 3 in the traditional way often requires an independent installation position and fastening point, which leads to the rapid occupation of the planar space. This invention allows multiple sets of auxiliary brackets 21 to be stably stacked and installed in the axial direction of the same first bolt 4, so that a far greater number of connectors 3 can be densely accommodated in the same connecting plate area of ​​the main bracket 1 than before, reserving valuable space for the layout of other vehicle systems.

[0037] Secondly, this structure significantly enhances the versatility and flexibility of the main bracket 1. By adjusting the number of auxiliary brackets 21 installed on a single first bolt 4, the total number of connectors 3 that the main bracket 1 can support can be flexibly adjusted according to the specific electrical requirements of different vehicle models and configurations, without changing the basic structure of the main bracket 1 or redesigning the installation points. Through the above modular concept, the main bracket 1 can adapt to the needs of various vehicle platforms and functional configurations, reduce the types of parts, lower development and manufacturing costs, and simplify the production assembly and later modification and upgrade process.

[0038] One set of auxiliary brackets 21 has a first pin hole, and the main bracket 1 has a second pin hole. Rubber pins 5 are inserted into the first pin hole and the second pin hole in sequence. During the operation of commercial vehicles, a lot of vibration will be generated. In order to absorb the vibration, rubber is used to fill the space between the auxiliary brackets 21 and the main bracket 1 to absorb the vibration, thereby making the integrated electrical components more reliable and reducing the probability of fatigue fracture. Rubber pads can also be fitted on the first bolt 4. At the same time, rubber pads can also be added between the first connecting plate 111 and the second connecting plate 212 to avoid the probability of rigid collision, thereby extending the service life of the integrated electrical components.

[0039] The ear plate 11 of the present invention includes three sets, and a plug-in seat 3 is installed between every two sets of ear plates 11. At the same time, multiple sets of plug-in seats 3 can be installed between each set of ear plates 11, thereby improving the installation capacity on the main bracket 1 and enabling it to adapt to more commercial vehicle models.

[0040] The main bracket 1 has a connection hole 13, and the connecting screw passes through the connection hole 13 and is screwed onto the vehicle body of the commercial vehicle. The main bracket 1 of the present invention is also installed on the vehicle body by the connecting screw, which facilitates subsequent maintenance or replacement.

[0041] 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 will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
