Detailed Implementation

[0019] The present application will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0020] like Figures 1-4 As shown, an aluminum profile for automotive parts includes a control arm body 1. Each end of the control arm body 1 is provided with a bushing seat 2. The bushing seat 2 and the control arm body 1 are integrally formed. The inner wall of the bushing seat 2 is provided with a pair of receiving grooves 21. The receiving grooves 21 are filled with lubricating oil 210. A sealing plate 3 is provided at the opening of the receiving groove 21. The upper part of the outer wall of the sealing plate 3 is connected to the inner wall of the receiving groove 21 by a first adhesive block 31. The lower part of the outer wall of the sealing plate 3 is located outside the receiving groove 21. The sealing plate 3 is made of a brittle material.

[0021] One bushing seat 2 is connected to one end of the control arm body 1, and the other bushing seat 2 is connected to the other end of the control arm body 1. Since both bushing seats 2 and the control arm body 1 are integrally formed, the connection strength between the control arm body 1 and the bushing seat 2 is effectively guaranteed, and the bushing seat 2 is prevented from detaching from the control arm body 1. Furthermore, during the process of inserting the bushing into the bushing seat 2, since the lower part of the outer wall of the sealing plate 3 is located outside the receiving groove 21, interference occurs between the bushing and the lower part of the outer wall of the sealing plate 3. Thus, by impacting the sealing plate 3 with the end of the bushing, the brittle sealing plate 3 is broken, and the lubricating oil 210 in the receiving groove 21 is automatically discharged. At this time, by repeatedly pushing and pulling the bushing, the fragments of the sealing plate 3 can be pushed to the outside of the bushing seat 2. At the same time, the lubricating oil 210 can be evenly applied to the inner wall of the bushing seat 2. This facilitates the installation of the bushing in the bushing seat 2. While achieving a reliable connection between the bushing seat 2 and the control arm body 1, it reduces the difficulty of installing the bushing in the bushing seat 2 and improves the installation efficiency.

[0022] The upper part of the outer wall of the sealing plate 3 is provided with several mounting grooves 32. Each mounting groove 32 is provided with a first adhesive block 31. One side of the first adhesive block 31 is bonded to the inner wall of the mounting groove 32, and the other side of the first adhesive block 31 is attached to the inner wall of the receiving groove 21. The first adhesive block 31 is provided in the mounting groove 32, which can reliably achieve the bonding between the sealing plate 3 and the inner wall of the receiving groove 21, ensuring that the sealing plate 3 can achieve the function of sealing the receiving groove 21 and preventing the lubricating oil 210 from leaking out of the bushing seat 2 before the bushing is installed.

[0023] The inner wall of the bushing seat 2 is provided with a pair of sliding grooves 22 extending along the axial direction of the bushing seat 2 and penetrating through the bushing seat 2. The sliding grooves 22 are dovetail grooves, and sliding blocks 23 are fitted in the sliding grooves 22. The sliding blocks 23 can slide into the sliding grooves 22 from the front side of the bushing seat 2 and slide out of the sliding grooves 22 from the back side of the bushing seat 2, and the sliding blocks 23 are used to impact the sealing plate 3. The sliding grooves 22 are dovetail grooves, and one end of the sliding grooves 22 communicates with the front side of the bushing seat 2, and the other end of the sliding grooves 22 communicates with the back side of the bushing seat 2, so that the sliding blocks 23 can freely slide into or out of the sliding grooves 22. Before the bushing is installed, the sliding blocks 23 can be slid into the sliding grooves 22. In this way, when the bushing is inserted into the bushing seat 2, the bushing pushes the sliding blocks 23 and impacts the sealing plate 3, ensuring that the sealing plate 3 can be smoothly broken, and further ensuring that the lubricating oil 210 in the accommodation groove 21 can automatically flow out when the bushing is installed, thereby reducing the difficulty of installing the bushing.

[0024] One end of the sliding block 23 is fitted in the sliding groove 22, and the other end of the sliding block 23 is located outside the sliding groove 22. The other end of the sliding block 23 is provided with a tapered spike 230, which faces the lower part of the outer wall of the sealing plate 3. The tapered spike 230 is provided on the sliding block 23, which improves the breaking effect of the sealing plate 3 and ensures that the sealing plate 3 can be broken into small pieces, thereby facilitating the outward discharge of the sealing plate 3, preventing the fragments of the sealing plate 3 from being stuck between the outer wall of the bushing and the inner wall of the bushing seat 2, and improving the reliability of the installation of the bushing in the bushing seat 2.

[0025] The bottom of the accommodation groove 21 is provided with a bottom groove 24, and the bottom groove 24 is provided with an air bag 241. The outer wall of the air bag 241 and the groove bottom of the bottom groove 24 are connected by a second adhesive block 242. When the sealing plate 3 closes the accommodation groove 21, the outer wall of the air bag 241 is in contact with the inner wall of the bottom groove 24 and is in a compressed state. When the sealing plate 3 is broken by impact, one side of the air bag 241 is connected to the groove bottom of the bottom groove 24 under the action of the second adhesive block 242, and the other side of the air bag 241 faces the accommodation groove 21. The air bag 241 will expand from the compressed state and move from the bottom groove 24 to the accommodation groove 21, and in this process, the air bag 241 will form a pushing action on the lubricating oil 210, ensuring that the lubricating oil 210 in the accommodation groove 21 can flow onto the inner wall of the bushing seat 2, thereby playing a lubricating role on the bushing.

[0026] The above embodiments are only preferred embodiments of the present application, and cannot be used to limit the scope of protection of the present application. Any non-essential changes and substitutions made by those skilled in the art on the basis of the present application are within the scope of protection of the present application.
