Description

Technical Field

[0001] This application relates to the field of vehicle chassis technology, and more particularly to a rear suspension control arm and a vehicle. Background Technology

[0002] The rear suspension control arm is one of the main components of a car chassis suspension. During driving, it is constantly subjected to vertical forces transmitted from the wheels, and in addition to vertical forces, it is also subjected to lateral impacts when encountering potholes or lateral impacts.

[0003] The rear suspension control arm is used to connect the rear subframe and the steering knuckle, and also to house the springs. It doesn't have many other functions. However, the wiring harness in the rear suspension area needs to be secured. Therefore, expanding the function of the rear suspension control arm to secure the wiring harness is a problem that needs to be considered. Utility Model Content

[0004] In order to solve the above-mentioned technical problems, or at least partially solve the above-mentioned technical problems, this application provides a rear suspension control arm and a vehicle, so as to fix the bracket of the constraint harness by adding fasteners to the control arm body, thereby expanding the function of the rear suspension control arm.

[0005] The first aspect of this application provides a rear suspension control arm, comprising: The control arm body includes a base plate and two side walls respectively disposed on opposite sides of the base plate, and each side wall has a flange extending from the top of the top of the side wall away from the other side wall; Fasteners are provided on the flange, the fasteners being configured to secure a wiring harness bracket, the wiring harness bracket being configured to restrain the wiring harness of the vehicle.

[0006] The rear suspension control arm provided in this embodiment features fasteners mounted on a flange. These fasteners secure a wiring harness bracket that restrains the vehicle's wiring harness, thus enabling the rear suspension control arm to constrain the wiring harness and expanding its functionality. Furthermore, the fasteners' placement on the flange and the wiring harness bracket's constraint prevent interference with the control arm's base plate and sidewalls, ensuring the structural integrity and basic functionality of the rear suspension control arm.

[0007] In some embodiments, the fastener has a threaded hole, and the flange has a through hole corresponding to the position of the threaded hole.

[0008] The fastener has a threaded hole, which can be used to fix the wiring harness bracket with a bolt that mates with the threaded hole. When installing the wiring harness bracket, the bolt passes through the wiring harness bracket and the through hole and then extends into the threaded hole. The engagement of the bolt and the threaded hole enables the detachable installation of the wiring harness bracket. This facilitates the removal of the wiring harness bracket when repairing or replacing the rear suspension control arm, avoiding damage to the wiring harness.

[0009] In some embodiments, the fastener is welded to the flange; And / or, the fastener is located on the side of the flange facing away from the base plate.

[0010] Welding is used to fix the fasteners, which provides high fixing strength and can improve the problem of fasteners loosening after long-term use.

[0011] The fasteners are located on the side of the flange facing away from the base plate. This provides relatively more space on the outer side when fixing the fasteners, preventing the side wall from affecting the tooling used to fix the fasteners. Furthermore, after the rear suspension control arm is installed in the vehicle, the wiring harness bracket is located on the lower side of the flange, preventing the wiring harness bracket from occupying the upper space of the rear suspension control arm. This avoids the need to consider avoiding the wiring harness bracket during the installation of the rear suspension control arm, and consequently, prevents the wiring harness bracket's placement from affecting other structures of the vehicle's chassis.

[0012] In some embodiments, the flange includes a first portion and a second portion, the first portion having an mounting area for securing the fastener, the second portion extending from the first portion toward the base plate, and the second portion having a notch at a position corresponding to the mounting area.

[0013] The aforementioned flange extends along the length of the control arm body. The first part is a continuous whole used to fix the fasteners, while the second part is not a continuous whole, but has a notch opened at the position corresponding to the installation area. Thus, the second part actually includes at least two segments, and the aforementioned notch is formed between two adjacent segments. This not only facilitates the use of stamping to form the control arm body, but also makes it easier to fix the fasteners by extending the electrodes on the tooling for fixing the fasteners into both sides of the thickness direction of the first part through the notch when fixing the fasteners by welding.

[0014] In some embodiments, the control arm body is formed by stamping.

[0015] The control arm body has good overall integrity and high structural strength.

[0016] In some embodiments, the device further includes a wire harness bracket and a locking member, wherein the wire harness bracket and the fastener are respectively disposed on both sides of the flange thickness direction, and the locking member is connected to the fastener to fix the wire harness bracket.

[0017] By setting up a wiring harness bracket and a locking device, the locking device and fastener work together to fix the wiring harness bracket. In this way, the wiring harness can be constrained by the wiring harness bracket, so that the rear suspension control arm has the function of constraining the wiring harness.

[0018] In some embodiments, a limiting hole is provided on the flange; The wire harness bracket also includes a limiting part that extends into the limiting hole to limit the rotation of the wire harness bracket.

[0019] When fixing the wire harness bracket, fasteners and locking parts secure the wire harness bracket, while limiting parts and limiting holes cooperate to limit the wire harness bracket and prevent it from rotating.

[0020] In some embodiments, a spring tray for supporting the spring is also included, the spring tray being connected to and located between the two sidewalls, the spring tray having a central boss for positioning the spring.

[0021] The spring tray serves to support the spring and also acts as a reinforcement to improve the structural strength of the rear suspension control arm.

[0022] In some embodiments, at least one reinforcing plate is further included, which is welded to the two side walls and is located at one end of the control arm body that is connected to the rear subframe.

[0023] The reinforcement plate can improve the strength of the control arm body at the end connected to the rear subframe, thereby improving the connection stability between the control arm body and the rear subframe.

[0024] A second aspect of this application provides a vehicle including a rear suspension control arm as described in any of the preceding claims.

[0025] The vehicle provided in this application has the beneficial effects of the rear suspension control arm described in any of the above claims because it includes the rear suspension control arm described in any of the above claims. Attached Figure Description

[0030] To better understand the above-mentioned objectives, features, and advantages of this application, the solution of this application will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0031] Many specific details are set forth in the following description in order to provide a full understanding of this application, but this application may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of this application, and not all embodiments.

[0032] The rear suspension control arm is one of the main components of a car chassis suspension. During driving, it is constantly subjected to vertical forces transmitted from the wheels, and in addition to vertical forces, it is also subjected to lateral impacts when encountering potholes or lateral impacts.

[0033] The rear suspension control arm connects the rear subframe and the steering knuckle, and also houses the springs. It has few other functions. The wiring harness in the rear suspension area needs to be secured. For example, in current technology, the wiring harness is secured to the steering knuckle. Since the steering knuckle is relatively thick, the wiring harness can be secured to the steering knuckle by inserting a bracket into a slot on the steering knuckle. However, the wiring harness is either not removable or difficult to remove, making subsequent maintenance difficult. For sheet metal parts like the control arm, the thickness is relatively thin, and using a plug-in method can easily lead to problems with the wiring harness not being securely secured. Therefore, it is necessary to consider how to securely fix the wiring harness to the control arm.

[0034] Based on this, this application provides a rear suspension control arm, which can fix the wiring harness bracket of the constrained wiring harness by adding fasteners to the control arm body, thereby expanding the function of the rear suspension control arm.

[0035] Reference Figures 1 to 5 Some embodiments of this application provide a rear suspension control arm, including a control arm body 1 and a fastener 2.

[0036] The control arm body 1 includes a base plate 11 and two side walls 12 respectively disposed on opposite sides of the base plate 11. The top of each side wall 12 is provided with a flange 13 extending away from the other side wall 12.

[0037] Reference Figure 1 and Figure 2 The control arm body 1 connects the rear subframe and the steering knuckle. The aforementioned base plate 11 and two side walls 12 form a U-shaped structure. The top of the side wall 12 refers to the end of the side wall 12 that is relatively far from the base plate 11. The two side walls 12 connect the rear subframe and the steering knuckle, while the flanges 13 enhance the structural strength of the control arm body 1. Furthermore, the base plate 11, the two side walls 12, and the two flanges 13 constituting the control arm body 1 are integrally formed, for example, the control arm body 1 is stamped, resulting in good integrity and high structural strength.

[0038] The fastener 2 is provided on the flange 13. The fastener 2 is used to fix the wiring harness bracket 5. The wiring harness bracket 5 is used to constrain the vehicle's wiring harness.

[0039] It should be noted that the aforementioned wire harness bracket 5 can be a structure of the wire harness itself. For example, the wire harness bracket 5 and the wire harness can be pre-fixed as one unit, and the wire harness can be fixed by fastener 2 during installation. Alternatively, the wire harness bracket 5 and the wire harness can be separate units. After the wire harness bracket 5 is fixed by fastener 2, the wire harness is then fixed to the wire harness bracket 5.

[0040] The rear suspension control arm provided in this embodiment of the application, by setting a fastener 2 on the flange 13, can use the fastener 2 to fix the wiring harness bracket 5, thereby enabling the rear suspension control arm to have the function of constraining the wiring harness and thus expanding the functionality of the rear suspension control arm. Moreover, by setting the fastener 2 on the flange 13 and constraining the wiring harness through the wiring harness bracket 5, interference with the base plate 11 and side wall 12 of the control arm body 1 can be avoided, ensuring the realization of the structure and basic functions of the rear suspension control arm.

[0041] In some embodiments, refer to Figure 1 and Figure 2 The fastener 2 is provided with a threaded hole, and the flange 13 is provided with a through hole at the position corresponding to the threaded hole.

[0042] Understandably, fastener 2 has a threaded hole, which can be used to secure the wiring harness bracket 5 using a bolt that mates with the threaded hole. When installing the wiring harness bracket 5, the bolt passes through the bracket and the through hole, then extends into the threaded hole. The engagement of the bolt and the threaded hole allows for the detachable installation of the wiring harness bracket 5. This facilitates disassembly of the wiring harness bracket 5 during maintenance or replacement of the rear suspension control arm, preventing damage to the wiring harness. Fastener 2 can be a nut, such as a square nut, for easy welding and securing.

[0043] In some embodiments, the fastener 2 is welded to the flange 13. Welding provides high fixing strength for the fastener 2 and can improve the problem of the fastener 2 easily loosening after long-term use.

[0044] In some embodiments, refer to Figure 1 and Figure 2 The fastener 2 is located on the side of the flange 13 facing away from the base plate 11. The side of the flange 13 facing away from the base plate 11 refers to the side of the flange 13 that is relatively far from the base plate 11 in the thickness direction. The side of the flange 13 closest to the base plate 11 refers to the side of the flange 13 that is relatively close to the base plate 11 in the thickness direction.

[0045] It should be noted that the fastener 2 is located on the side of the flange 13 away from the base plate 11. This provides a relatively large space on the outside when fixing the fastener 2, preventing the side wall 12 from affecting the tooling used to fix the fastener 2. Furthermore, after the rear suspension control arm is installed in the vehicle, the wiring harness bracket 5 is located on the lower side of the flange 13, preventing the wiring harness bracket 5 from occupying the upper space of the rear suspension control arm. This avoids the need to consider avoiding the wiring harness bracket 5 during the installation of the rear suspension control arm, and thus prevents the wiring harness bracket 5 from affecting other structures of the vehicle chassis.

[0046] Of course, the fastener 2 mentioned above can also be set on the side of the flange 13 near the base plate 11.

[0047] In some embodiments, refer to Figure 1 and Figure 2 The rear suspension control arm also includes a spring tray 3 for supporting the spring (not shown in the figure), the spring tray 3 is connected to the two side walls 12 and located between the two side walls 12, and the spring tray 3 has a central boss 31 for positioning the spring.

[0048] Understandably, the spring tray 3 can support the spring and also serve as a reinforcement to improve the structural strength of the rear suspension control arm.

[0049] Reference Figure 2The aforementioned spring tray 3 has a support portion and a reinforcing portion. The support portion is provided with a central boss 31, and the reinforcing portion extends from the support portion toward the end near the control arm body 1 where it connects to the steering knuckle.

[0050] Understandably, the spring tray 3 supports the spring through the support part, while the reinforcing part connecting the two side walls 12 can serve as a reinforcing plate 4 to strengthen the structure of the rear suspension control arm. In this way, a single component can serve a dual purpose, reducing the number of parts and assembly steps.

[0051] It should be noted that the spring tray 3 can be a stamped part, with its central boss 31 integrally stamped. Furthermore, to reduce weight, the central boss 31 has weight-reduction holes. Thus, the blank for the spring tray 3 is a plate-like structure with through holes, and the aforementioned central boss 31 is formed at the through holes after stamping. Alternatively, the spring tray 3 and the central boss 31 can be separate components, connected as one piece by welding. In this case, the central boss 31 is a tubular structure, which is beneficial for weight reduction.

[0052] In some embodiments, refer to Figure 1 The rear suspension control arm also includes at least one reinforcing plate 4, which is welded to two side walls 12. The reinforcing plate 4 is relatively close to the end of the control arm body 1 that is connected to the rear subframe.

[0053] Understandably, the aforementioned reinforcing plate 4 can improve the strength of the control arm body 1 at the end connected to the rear subframe, thereby improving the connection stability between the control arm body 1 and the rear subframe.

[0054] For example, refer to Figure 1 One of the aforementioned reinforcing plates 4 is provided.

[0055] In some embodiments, refer to Figure 2 and Figure 3 The aforementioned flange 13 includes a first part 131 and a second part 132. The first part 131 has an installation area for fixing fasteners 2. The second part 132 extends from the first part 131 toward the base plate 11, and the second part 132 has a notch 132a at the position corresponding to the installation area.

[0056] It should be noted that the aforementioned flange 13 extends along the length of the control arm body 1. The first part 131 is a continuous integral unit used to fix the fastener 2. However, the second part 132 is not a continuous integral unit, but rather has a notch 132a opened at the corresponding installation area. Thus, the second part 132 actually includes at least two segments, with the aforementioned notch 132a formed between two adjacent segments. This not only facilitates the use of stamping for the control arm body 1, but also allows the electrodes on the tooling for fixing the fastener 2 to extend through the notch 132a to both sides of the first part 131 in the thickness direction when fixing the fastener 2 by welding, thereby facilitating the fixing of the fastener 2.

[0057] In this case, the fastener 2 is selected to be fixed to the flange 13 by welding. In addition, the control arm body 1 is selected to be formed by stamping, so that the base plate 11, side wall 12 and flange 13 are integrally formed.

[0058] In some embodiments, refer to Figure 4 and Figure 5 The rear suspension control arm also includes a wiring harness bracket 5 and a locking member 6. The wiring harness bracket 5 and the fastener 2 are respectively located on both sides of the flange 13 in the thickness direction. The locking member 6 is connected to the fastener 2 to fix the wiring harness bracket 5.

[0059] Understandably, by setting up the wiring harness bracket 5 and the locking member 6, the locking member 6 and the fastener 2 cooperate to fix the wiring harness bracket 5. In this way, the wiring harness can be constrained by the wiring harness bracket 5, so that the rear suspension control arm has the function of constraining the wiring harness.

[0060] Furthermore, a limiting hole 1311 is provided on the aforementioned flange 13. The wire harness bracket 5 also includes a limiting part 51, which extends into the limiting hole 1311 to limit the rotation of the wire harness bracket 5.

[0061] In other words, when fixing the wire harness bracket 5, the fastener 2 and the locking member 6 fix the wire harness bracket 5, while the limiting part 51 and the limiting hole 1311 cooperate to limit the wire harness bracket 5 and prevent the wire harness bracket 5 from rotating.

[0062] Specifically, the fastener 2 has a threaded hole, and the locking member 6 is selected as a bolt that mates with the threaded hole. At this time, the flange 13 has a through hole for the bolt to pass through. After the bolt passes through the wire harness bracket 5 and the through hole, it mates with the threaded hole to fix the wire harness bracket 5. At the same time, the limiting part 51 extends into the limiting hole 1311 to limit the rotation of the wire harness bracket 5. This not only prevents the wire harness bracket 5 from rotating when the bolt is tightened, but also prevents the wire harness bracket 5 from rotating when the bolt becomes loose, thereby preventing the rotation of the wire harness bracket 5 from damaging the wire harness.

[0063] Furthermore, the fastener 2 is preferably located on the side of the flange 13 away from the base plate 11. This provides a relatively large outer space when fixing the fastener 2, preventing the side wall 12 from affecting the tooling used to fix the fastener 2. Moreover, after the rear suspension control arm is installed in the vehicle, the wiring harness bracket 5 is located on the lower side of the flange 13, preventing the wiring harness bracket 5 from occupying the upper space of the rear suspension control arm. This avoids the need to consider avoiding the wiring harness bracket 5 during the installation of the rear suspension control arm, and further prevents the wiring harness bracket 5 from affecting other structures of the vehicle chassis.

[0064] Reference Figure 1 and Figure 5 An example is provided of a rear suspension control arm, including a control arm body 1 and a fastener 2.

[0065] The control arm body 1 includes a base plate 11, two side walls 12 and two flanges 13. The two side walls 12 are respectively disposed on opposite sides of the base plate 11, and each flange 13 extends from the top of the side wall 12 away from the other side wall 12.

[0066] The fastener 2 is located on the side of the flange 13 facing away from the base plate 11 and is used to fix the wiring harness bracket 5 of the restraining wiring harness. The rear suspension control arm also includes the wiring harness bracket 5 and a locking member 6. The wiring harness bracket 5 is located on the side of the flange 13 near the base plate 11, and the locking member 6 is connected to the fastener 2 to fix the wiring harness bracket 5. A limiting hole 1311 is provided on the flange 13. The wiring harness bracket 5 also includes a limiting part 51, which extends into the limiting hole 1311 to limit the rotation of the wiring harness bracket 5.

[0067] The side of the flange 13 away from the base plate 11 refers to the side of the flange 13 that is relatively far away from the base plate 11 in the thickness direction. The side of the flange 13 close to the base plate 11 refers to the side of the flange 13 that is relatively close to the base plate 11 in the thickness direction.

[0068] The fastener 2 has a threaded hole, and the flange 13 has a through hole at the position corresponding to the threaded hole. The fastener 2 is a bolt. After passing through the wire harness bracket 5 and the through hole, the bolt engages with the threaded hole to fix the wire harness bracket 5.

[0069] The fastener 2 is welded to the flange 13. The flange 13 includes a first part 131 and a second part 132. The first part 131 has an installation area for fixing the fastener 2. The second part 132 extends from the first part 131 toward the base plate 11 and has a notch 132a at the position corresponding to the installation area.

[0070] In other words, the flange 13 extends along the length of the control arm body 1. The first part 131 is a continuous whole used to fix the fastener 2, while the second part 132 is not a continuous whole. Instead, a notch 132a is opened at the position corresponding to the installation area. Thus, the second part 132 actually includes at least two segments, and the notch 132a is formed between two adjacent segments. This not only facilitates the use of stamping for the control arm body 1, but also makes it easier for the electrodes on the tooling for fixing the fastener 2 to extend from the notch 132a to both sides of the thickness direction of the first part 131 when the fastener 2 is fixed by welding. This facilitates the welding and fixing of the fastener 2.
