[0043] The grounding point, also known as the earthing point, is a critical component of automotive electrical systems, playing a vital role in the normal operation, stability, and safety of a vehicle. The grounding point is the negative terminal connection point in the automotive circuit, typically connected to the vehicle body or engine to ensure that current can safely flow back to the battery. As part of the current loop, the grounding point ensures that the vehicle's internal electronic devices receive a stable voltage, thus maintaining their proper function. By connecting all negative terminals to the vehicle body, the number of negative cables can be reduced, minimizing the number of wiring harnesses and simplifying the circuit structure.
[0044] Common grounding points include the battery negative terminal grounded to the vehicle body, the engine grounding point, the starter motor grounding point, and grounding points of other electrical equipment to the vehicle body. These grounding points are connected to the vehicle body via grounding wires, forming a complete current loop.
[0045] In existing vehicles, the powertrain's grounding point is located on the transmission, and the grounding point on the transmission is electrically connected to the vehicle body via a grounding wire.
[0046] In existing vehicles, the grounding point on the transmission is below the vehicle's wading line.
[0047] When a vehicle is constantly wading through water, the grounding point on the transmission is below the wading line, making the grounding wire susceptible to corrosion and rust. This can easily lead to the grounding wire breaking due to corrosion, which in turn affects the performance and service life of the powertrain.
[0048] To address the technical problem that existing powertrains have grounding points below the wading line, making the grounding wires susceptible to corrosion and rust, this application proposes a suspension structure and vehicle. The suspension structure includes a conductive suspension arm, a vibration-absorbing component, and a suspension base. The suspension base is used to connect to the vehicle body. One end of the conductive suspension arm is connected to the suspension base via the vibration-absorbing component, and the other end of the conductive suspension arm is used to connect to the upper suspension mounting point of the vehicle's powertrain. A grounding mounting part is provided on the conductive suspension arm, which is electrically connected to the powertrain via the conductive suspension arm. The grounding mounting part is used to electrically connect to the vehicle body via a grounding wire, thereby enabling the powertrain to be electrically connected to the vehicle body.
[0049] The conductive suspension arm of this application is connected to the upper suspension mounting point of the powertrain. The conductive suspension arm has a conductive function, and the ground mounting part on the conductive suspension arm is electrically connected to the powertrain through the conductive suspension arm. Because the upper suspension mounting point of the powertrain is located above the vehicle's wading line, that is, the conductive suspension arm is located above the vehicle's wading line, the ground mounting part set on the conductive suspension arm is located above the wading line. That is, the ground mounting part is higher than the grounding point on the existing transmission, so the grounding wire connected to the ground mounting part is not easily corroded and broken by water wading, thereby improving the performance and service life of the powertrain.
[0050] The technical solution of the application will be described in detail below with reference to the accompanying drawings and specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.
[0051] Reference Figures 1 to 6 As shown, Figure 1 A schematic diagram of the structure when the suspension structure provided in the embodiments of this application is connected to the longitudinal beams of the vehicle body and the powertrain; Figure 2 A schematic diagram of the structure when the suspension structure provided in the embodiments of this application is connected to the longitudinal beam of the vehicle body; Figure 3 A schematic diagram of the structure when the suspension structure is connected to the ground wire, as provided in the embodiments of this application; Figure 4 for Figure 3 Enlarged structural diagram at point A; Figure 5 An exploded view of the suspension structure provided in an embodiment of this application; Figure 6 This is a schematic diagram of the suspension structure connected to the vehicle body and controller in an embodiment of this application.
[0052] In the embodiments of this application, reference is made to Figure 1 , Figure 2 and Figure 5As shown, an embodiment of this application provides a suspension structure, including a conductive suspension arm 100, a vibration-absorbing component 200, and a suspension base 300. The suspension base 300 is used to connect to the vehicle body 10. One end of the conductive suspension arm 100 is connected to the suspension base 300 through the vibration-absorbing component 200, and the other end of the conductive suspension arm 100 is used to connect to the upper suspension mounting point of the vehicle's powertrain 20.
[0053] A grounding mounting part 110 is provided on the conductive suspension arm 100. The grounding mounting part 110 is electrically connected to the powertrain 20 through the conductive suspension arm 100. The grounding mounting part 110 is used to electrically connect to the vehicle body 10 through the grounding wire 400 so that the powertrain 20 and the vehicle body 10 are electrically connected.
[0054] The suspension structure of this application embodiment is used to mount the powertrain 20 on the vehicle body 10. The conductive suspension arm 100 of the suspension structure can be a conductive metal structure and has a conductive function. One end of the conductive suspension arm 100 is connected to the upper suspension mounting point of the powertrain 20 of the vehicle, so that the electricity of the powertrain 20 can be conducted to the conductive suspension arm 100. In this embodiment, the conductive suspension arm 100 is rigidly connected to the upper suspension mounting point of the powertrain 20.
[0055] The conductive suspension arm 100 is connected to the suspension base 300 through the vibration absorption component 200. The vibration absorption component 200 has the functions of buffering and damping, effectively reducing the vibration force transmitted from the powertrain 20, which is the vibration source, to the vehicle body 10, i.e., active vibration isolation; at the same time, it can also attenuate the vibration force transmitted from the road surface to the powertrain 20, i.e., passive vibration isolation.
[0056] The vibration-absorbing component 200 can be a rubber cup, a spring, or a combination of rubber and metal parts, wherein the combination also includes a liquid, such as a damping fluid. It should be noted that the vibration-absorbing component 200 can be an existing suspended vibration-absorbing component 200.
[0057] The suspension base 300 is fixed to the body 10. Specifically, the suspension base 300 can be fixed to the longitudinal beam of the body 10. The suspension base 300 can be a metal structure with high structural strength and rigidity to ensure the stability of the powertrain 20.
[0058] The grounding mounting part 110 is provided on the conductive suspension arm 100. Because the conductive suspension arm 100 has a conductive function, the powertrain 20 is electrically connected to the conductive suspension arm 100. Consequently, the grounding mounting part 110 can be electrically connected to the powertrain 20 through the conductive suspension arm 100. The grounding mounting part 110 is provided with a ground wire 400, and the other end of the ground wire 400 is electrically connected to the vehicle body 10, thereby making the powertrain 20 electrically connected to the vehicle body 10. That is, by providing the grounding mounting part 110 on the conductive suspension arm 100, this application ensures that the grounding point of the powertrain 20 is located on the grounding mounting part 110 on the conductive suspension arm 100. The powertrain 20 is kept at the same potential as the vehicle body 10 through the grounding mounting part 110 on the conductive suspension arm 100, thus avoiding excessive voltage of the powertrain 20.
[0059] The conductive suspension arm 100 of the suspension structure of this application is connected to the upper suspension mounting point of the powertrain 20. The conductive suspension arm 100 has a conductive function, and the ground mounting part 110 on the conductive suspension arm 100 is electrically connected to the powertrain 20 through the conductive suspension arm 100. Because the upper suspension mounting point of the powertrain 20 is located above the wading line of the vehicle, that is, the conductive suspension arm 100 is located above the wading line of the vehicle, the ground mounting part 110 provided on the conductive suspension arm 100 is located above the wading line. That is, the ground mounting part 110 is located higher than the grounding point on the existing gearbox, so the ground wire 400 connected to the ground mounting part 110 is not easily corroded and broken by water wading, thereby improving the performance and service life of the powertrain 20.
[0060] In one embodiment, reference is made to... Figure 2 , Figure 4 and Figure 5 As shown, it also includes a grounding fastener 500. The conductive suspension arm 100 is provided with a grounding mounting hole, which forms a grounding mounting part 110. The grounding fastener 500 is used to connect the grounding terminal 410 of the grounding wire 400 to the grounding mounting hole.
[0061] In this embodiment, the grounding fastener 500 can be a connecting bolt, and the grounding mounting hole is a threaded hole. The grounding fastener 500 threads the grounding terminal 410 of the grounding wire 400 onto the grounding mounting hole, thereby ensuring the fixation of the grounding terminal 410 and making the grounding terminal 410 electrically connected to the conductive suspension arm 100.
[0062] It should be noted that the grounding fastener 500 can also be a snap-fit component, a welded component, etc.
[0063] In other embodiments, refer to Figure 4 and Figure 5As shown, a limiting groove 120 is also provided on the conductive suspension arm 100. The limiting groove 120 matches the limiting part 411 of the ground terminal 410. The limiting groove 120 is used to limit the rotation of the ground terminal 410.
[0064] In this embodiment, after the ground terminal 410 is installed on the ground mounting part 110, the limiting part 411 of the ground terminal 410 can be locked in the limiting groove 120, thereby preventing the ground terminal 410 from rotating and thus preventing the ground terminal 410 from becoming loose.
[0065] In another embodiment, reference Figure 1 and Figure 2 As shown, it also includes a powertrain fastener 600, and the conductive suspension arm 100 is also provided with a plurality of powertrain mounting holes 130. The powertrain fastener 600 is used to connect the upper suspension mounting point of the powertrain 20 to the powertrain mounting holes 130.
[0066] In this embodiment, the powertrain fastener 600 can be a connecting bolt, which connects the upper suspension mounting point of the powertrain 20 to the powertrain mounting hole 130, thereby fixing the powertrain 20 to the conductive suspension arm 100.
[0067] It should be noted that the 600 power fastener can also be a snap-fit component, a welded component, etc.
[0068] In some embodiments, reference is made to Figure 3 and Figure 5 As shown, a controller mounting part 310 is provided on the suspension base 300, and the controller mounting part 310 is used to mount the vehicle controller 30.
[0069] In this embodiment, by providing a controller mounting part 310 on the suspension base 300, the vehicle controller 30 can be mounted on the suspension base 300. The controller 30 can be an engine control module (ECM) or a vehicle control unit (VCU), thereby making the suspension structure of this application more integrated, facilitating the installation of the controller 30, making the space of the vehicle body 10 more compact, improving the space utilization of the vehicle body 10, and eliminating the need for the controller 30 mounting bracket on the vehicle body 10.
[0070] In another possible embodiment, refer to Figure 2 and Figure 6 As shown, it also includes a controller fastener 700. The suspension base 300 is provided with at least one controller mounting hole, which forms a controller mounting part 310. The controller fastener 700 is used to connect the controller 30 to the controller mounting hole.
[0071] In this embodiment, the controller mounting hole can be a bolt hole, and the controller fastener 700 can be a connecting bolt. The connecting bolt connects the controller 30 to the bolt hole, thereby enabling the controller 30 to be mounted on the suspension base 300.
[0072] It should be noted that the controller fastener 700 can also be a snap-fit component, a welded component, etc.
[0073] In one possible embodiment, refer to Figure 2 and Figure 6 As shown, it also includes a first body fastener 800, and the suspension base 300 is also provided with a plurality of body vertical mounting holes 320. The first body fastener 800 is used to connect the suspension base 300 to the body 10 through the body vertical mounting holes 320, and the first body fastener 800 is perpendicular to the body 10.
[0074] In this embodiment, the first body fastener 800 vertically mounts the suspension base 300 onto the body 10, meaning that both the first body fastener 800 and the body vertical mounting hole 320 are perpendicular to the body 10.
[0075] Furthermore, the suspension base 300 is located on the upper surface of the longitudinal beam of the vehicle body 10. Thus, the longitudinal beam of the vehicle body 10 provides support for the suspension base 300.
[0076] It should be noted that the vertical mounting hole 320 on the vehicle body can be a bolt hole, etc., and the first vehicle body fastener 800 can be a connecting bolt, a snap-fit, a welded part, etc.
[0077] In some possible embodiments, refer to Figure 2 and Figure 6 As shown, it also includes a second body fastener 900. The suspension base 300 is provided with a body side mounting part 330. The second body fastener 900 is used to connect the suspension base 300 to the body 10 through the body side mounting part 330, and the second body fastener 900 is perpendicular to the first body fastener 800.
[0078] In this embodiment, the side mounting part is connected to the side of the vehicle body 10. When the side of the vehicle body 10 is impacted, the suspension base 300 increases the rigidity of the side of the vehicle body 10.
[0079] Furthermore, with the combined action of the first body fastener 800 and the second body fastener 900, the suspension base 300 is more stably fixed to the body 10. When the suspension base 300 is subjected to force in multiple directions, the anti-detachment ability of the suspension base 300 is improved.
[0080] It should be noted that the side mounting part can be a circular hole, a semi-circular mounting hole, an oblong hole, etc., and the second body fastener 900 can be a connecting bolt, a snap-fit, a welded part, etc.
[0081] In some possible embodiments, ground wire 400 is a braided ground wire.
[0082] In existing vehicles, the grounding point of the powertrain 20 is located on the transmission. The grounding point on the transmission is electrically connected to the vehicle body 10 through the grounding wire 400. Since the grounding point on the transmission is below the vehicle's wading line, the grounding wire 400 must be waterproof. That is, the grounding wire 400 of the existing powertrain 20 grounding point needs to use ordinary ultra-flexible grounding wire. Ordinary ultra-flexible grounding wire is relatively stiff and has poor vibration isolation and sound insulation effects. Vibrations on the powertrain 20 will be transmitted to the vehicle body 10 through the ordinary ultra-flexible grounding wire, causing the vehicle body 10 to vibrate significantly.
[0083] Braided grounding wires have poorer waterproof performance than ordinary ultra-flexible grounding wires, but better vibration isolation and sound insulation. Because the suspension structure of this application places the grounding mounting part 110 above the wading line, it effectively solves the problem of poor waterproofing and corrosion of braided grounding wires, thus enabling the application of braided grounding wires in the powertrain 20. In this embodiment, the grounding wire 400 is a braided grounding wire. The braided grounding wire reduces the vibration transmitted from the powertrain 20 to the body 10 compared to the vibration of ordinary ultra-flexible grounding wires, thereby reducing the vibration of the body 10 and improving the NVH performance of the body 10.
[0084] A second aspect of this application provides a vehicle including a body 10 and a powertrain 20, and also includes a suspension structure of any of the above embodiments, wherein the upper suspension mounting point of the powertrain 20 is mounted on the body 10 through the suspension structure.
[0085] In this embodiment of the application, the powertrain 20 of the vehicle is mounted on the vehicle body 10 via the suspension structure of this embodiment. The suspension structure of this embodiment includes a conductive suspension arm 100, a vibration-absorbing component 200, and a suspension base 300. The suspension base 300 is used to connect to the vehicle body 10. One end of the conductive suspension arm 100 is connected to the suspension base 300 via the vibration-absorbing component 200, and the other end of the conductive suspension arm 100 is used to connect to the upper suspension mounting point of the powertrain 20 of the vehicle. A ground mounting part 110 is provided on the conductive suspension arm 100. The ground mounting part 110 is electrically connected to the powertrain 20 via the conductive suspension arm 100. The ground mounting part 110 is used to electrically connect to the vehicle body 10 via a ground wire 400, so that the powertrain 20 is electrically connected to the vehicle body 10.
[0086] In this embodiment, the conductive suspension arm 100 of the vehicle is connected to the upper suspension mounting point of the powertrain 20. The conductive suspension arm 100 has a conductive function, and the ground mounting part 110 on the conductive suspension arm 100 is electrically connected to the powertrain 20 through the conductive suspension arm 100. Because the upper suspension mounting point of the powertrain 20 is located above the wading line of the vehicle, that is, the conductive suspension arm 100 is located above the wading line of the vehicle, the ground mounting part 110 provided on the conductive suspension arm 100 is located above the wading line. That is, the ground mounting part 110 is located higher than the grounding point on the existing gearbox, so the ground wire 400 connected to the ground mounting part 110 is not easily corroded and broken by water wading, thereby improving the performance and service life of the powertrain 20.
