Description

Technical Field

[0001] The utility model belongs to the technical field of automotive parts, and particularly relates to a rear upper control arm assembly. Background Technique

[0002] An automotive control arm is a key part of an automotive suspension system, playing a crucial role in the suspension system and having a significant impact on the ride comfort and handling stability of the vehicle. The control arm mainly functions as a guide and a force transmitter, effectively transmitting various forces on the wheel to the vehicle body while ensuring that the wheel moves along a predetermined trajectory. The automotive control arm elastically connects the wheel and the vehicle body through a ball joint or a bushing, ensuring that the vehicle can maintain a stable and safe driving state under various road conditions. The existing rear upper control arm is heavy, and during actual design and installation, wire harness clips need to be installed, and factors such as whether the wire harness is assembled in place and disassembled need to be considered, with many limiting factors. Summary of the Invention

[0003] The problem to be solved by the utility model is to provide a rear upper control arm assembly, which is lighter in weight, facilitates the installation and disassembly of wire harness clips, and is easy to judge whether the assembly is in place.

[0004] The technical solution provided by the utility model is: a rear upper control arm assembly, including a rear upper control arm body in a U shape. The rear upper control arm body includes a control arm front plate and a control arm rear plate. The two sides of the control arm front plate and the two sides of the control arm rear plate have folding edges. The folding edges on the same side of the control arm front plate and the control arm rear plate are bent and folded in the opposite direction and are connected together by arc welding to form an inner cavity; both ends of the control arm front plate and the control arm rear plate respectively have connecting shaft holes, the shaft holes at the same end of the control arm front plate and the control arm rear plate are coaxial and have the same diameter, and both ends of the rear upper control arm body have openings respectively communicating with the cavity; a wire harness clip hole with a diameter of φ8 is opened in the middle of the control arm front plate, and a positioning hole with a diameter of φ12 is opened in the middle of the control arm rear plate, and the positioning hole is coaxial with the wire harness clip hole.

[0005] A wire harness hole and a process hole are provided on the rear upper control arm body.

[0006] By providing the control arm front plate and the control arm rear plate, with folding edges on both sides of the control arm front plate and both sides of the control arm rear plate, the folding edges on the same side of the control arm front plate and the control arm rear plate are bent and folded in the opposite direction and are connected together by arc welding to form an inner cavity, which not only ensures the strength of the part but also has a lighter weight. In addition, by setting a wire harness clip hole with a diameter of φ8 on the control arm front plate part and correspondingly setting a φ12 hole on the control arm rear plate, it can be observed whether the wire harness clip is installed in place, and the wire harness can be disassembled through this hole by using a tool, achieving the disassembly function.

[0008] Figure 2 is Figure 1 the top view of;

[0009] Figure 3 is Figure 1 the bottom view of. Specific embodiments

[0010] Refer to Figures 1-3 , the present utility model includes a rear front upper control arm body 1 in a U shape. The rear front upper control arm body 1 includes a control arm front plate 9 and a control arm rear plate 2. Both sides of the control arm front plate 9 and both sides of the control arm rear plate 2 have folding edges 3. The folding edges 3 on the same side of the control arm front plate 9 and the control arm rear plate 2 are bent and folded in the opposite direction and are connected together by arc welding to form an inner cavity 10; both ends of the control arm front plate 9 and the control arm rear plate 2 respectively have connecting shaft holes 4. The shaft holes 4 at the same end of the control arm front plate 9 and the control arm rear plate 2 are coaxial and have the same diameter. Both ends of the rear front upper control arm body 1 have openings 11 respectively communicating with the cavity 10; a wire harness buckle hole 5 with a diameter of φ8 is opened in the middle of the control arm front plate 9, and a positioning hole 6 with a diameter of φ12 is opened in the middle of the control arm rear plate 2. The positioning hole 6 is coaxial with the wire harness buckle hole 5.

[0011] A wire harness hole 7 and a process hole 8 are provided on the rear front upper control arm body 1.

[0012] The present utility model has a φ12 hole provided on the control arm rear plate, through which it can be observed whether the wire harness buckle is installed in place, and through this hole, the wire harness can be disassembled by tools, achieving the disassembly function. At the same time, the φ12 hole in the welding fixture can achieve the anti-misassembly function and the function of controlling the opening dimension.

[0013] The present utility model is formed by connecting the rear front upper control arm front plate and the rear front upper control arm rear plate together by arc welding. After welding is completed, a wire harness buckle is installed on the φ8 hole. Through the φ12 positioning hole on the control arm rear plate, it can be observed whether the wire harness buckle is installed in place, and through this hole, the wire harness can be disassembled by tools, achieving the disassembly function. During processing, a φ11 pin passes through the φ12 positioning hole in the welding fixture. Since the φ11 pin cannot pass through the φ8 hole, this can avoid misassembly of parts and achieve the anti-misassembly function. The normal fixture loading process is to first pass the φ12 hole of the control arm rear plate through the φ11 pin, and then assemble the control arm front plate. The φ11 pin cannot pass through the φ8 hole of the control arm front plate, which can control the control arm front plate to a certain position and avoid the opening between the two parts from being too small. This can also control the opening dimension of the parts through the length of the φ11 pin.
