Description

Technical Field

[0001] The invention relates to the technical field of vehicle accessories. Background Art

[0002] A series of devices used to change or maintain the direction of a car's movement or reversing is called a car steering system. The function of a car steering system is to control the direction of the car according to the driver's wishes. The car steering system is vital to the car's driving safety, so the parts of the car steering system are called safety parts, among which the second bridge swing arm is an important part of the car steering system.

[0003] At present, the traditional second-bridge swing arm includes a vertical arm and a side arm integrally formed with the vertical arm, wherein the side arm is located in the middle of the vertical arm; three connecting holes are opened on the vertical arm, and one connecting hole is opened on the side arm; when in use, the vertical arm swings around the connecting hole at the top end of the vertical arm, so that the top end of the vertical arm is subjected to relatively concentrated force, which makes the top end of the vertical arm easily deformed or damaged. Summary of the invention

[0004] The present invention is intended to provide a high-strength second-bridge swing arm to solve the problem that the second-bridge swing arm currently swings around its top end and is subjected to relatively concentrated force, causing the top end of the second-bridge swing arm to be easily deformed or damaged.

[0005] In order to achieve the above-mentioned purpose, the basic scheme of the present invention is as follows: a high-strength double-bridge swing arm, including a vertical arm and a side arm connected to the vertical arm, a first connecting hole is provided on the vertical arm and the side arm, a balancing arm is provided on the side wall of the vertical arm close to the first connecting hole, and a second connecting hole is provided on the balancing arm; a first angle is formed between the balancing arm and the vertical arm.

[0006] Advantages of the basic solution: This solution uses the first connecting hole on the vertical arm as the rotation center hole. When the second bridge swing arm swings, the horizontal arm can bear part of the force of the vertical arm. Compared with the existing technology, this solution can alleviate the force on the vertical arm through the balance arm, reduce the probability of deformation or damage of the vertical arm, enhance the strength of the second bridge swing arm, and extend its service life.

[0007] Furthermore, the first angle is an obtuse angle, a right angle, or an acute angle.

[0008] Through the above arrangement, when the first angle is an obtuse angle, a right angle or an acute angle, the force on the vertical arm can be relieved by the balance arm.

[0009] Furthermore, the balancing arm is arranged at the end of the vertical arm, and the length of the balancing arm is the same as the length of the vertical arm.

[0010] Through the above arrangement, when the second bridge swing arm swings, the vertical arm can swing more smoothly through the balance arm. Similarly, the balance arm can also swing more smoothly through the vertical arm.

[0011] Furthermore, the balancing arm and the vertical arm are integrally formed.

[0012] Through the above arrangement, the integral molding can improve the stability of the structure.

[0013] Furthermore, the balancing arm includes a horizontal section and a transition section, and a first transition angle is formed between the transition section and the vertical arm.

[0014] Through the above arrangement, the setting of the first transition angle can avoid other parts of the automobile steering system, so as to make better use of space.

[0015] Furthermore, an extension arm is provided between the vertical arm and the side arm, and both sides of the extension arm form a second angle with the vertical arm; the extension arm and the balance arm are located on both sides of the vertical arm.

[0016] Through the above arrangement, since the extension arm and the balance arm are located on both sides of the vertical arm, the left and right forces of the second bridge swing arm are more balanced when not in use.

[0017] Further, the extension arm is located in the middle of the vertical arm.

[0018] Through the above arrangement, the forces on the upper and lower ends of the vertical arm are more evenly distributed.

[0019] Furthermore, the extension arm is integrally formed with the vertical arm and the side arm.

[0020] Through the above arrangement, the integral molding can improve the stability of the structure.

[0021] Furthermore, a first groove, a second groove and a third groove are provided on the vertical arm, and the first groove is located at a first angle, the second groove is located at a second angle, and the third groove is located at another second angle; filling blocks are provided in the first groove, the second groove and the third groove.

[0022] Through the above arrangement, the filling block can prevent the balance arm and the vertical arm from changing position, and can also prevent the extension arm and the vertical arm from changing position, that is, avoid deformation of the entire second bridge swing arm.

[0023] Furthermore, an outer support arm is provided between two adjacent filling blocks, and the outer support arm is located inside the vertical arm; a fixing block is provided inside the outer support arm, and an inner support arm is provided between the fixing block and the filling block, and the inner support arm is located inside the vertical arm.

[0024] Through the above-mentioned arrangement, a triangular structure is formed by three filling blocks and three outer support arms. According to the stability of the triangle, the stability of preventing the entire second bridge swing arm from being deformed can be improved; and, a triangular structure can also be formed by a fixed block, two filling blocks, two inner support arms and one outer support arm. According to the stability of the triangle, the stability of preventing the entire second bridge swing arm from being deformed can be further improved. BRIEF DESCRIPTION OF THE DRAWINGS
