[0024] Example 1: A high-strength ball pin control arm with bracket, as shown in Figures 1-4, includes a main body 1 and a hollowed-out weight-reducing groove 13 disposed inside the main body 1. A spring pad mounting surface 8 is provided on the outer side of the hollowed-out weight-reducing groove 13. Several bracket mounting holes 6 are provided on the surface of the main body 1. A ball pin bracket 17 is installed above the bracket mounting holes 6. A triangular weight-reducing groove 2 and a long strip weight-reducing groove 5 are provided on one side surface of the main body 1. The control arm designed in this utility model is an integrated structure design. The hollowed-out weight-reducing groove 13 in the middle of the main body 1 can reduce the total weight of the control arm to the greatest extent. Moreover, the hollowed-out weight-reducing groove 13, i.e., the inner and outer surround of the spring pad mounting surface 8, is raised. This design can effectively lift the lower control arm after the control arm is installed on the car. The overall strength and load-bearing capacity are ensured; and the spring pads are effectively protected from damage caused by sand and gravel splashing during vehicle operation. Furthermore, the spring pads are effectively protected in water-crossing environments. The ball pin bracket 17, installed through the bracket mounting hole 6, is made of high-strength steel, maximizing the design freedom of the ball pin connection to the rear lower control arm and improving connection strength to enhance vehicle handling. Through the triangular weight-reduction groove 2 and the long strip weight-reduction groove 5, the weight of the product can be effectively reduced while maintaining the original material strength of the main body 1, thus reducing the product's weight and contributing to vehicle lightweighting. This simplifies the control arm installation structure to the greatest extent, enabling the vehicle to adapt to various complex road surfaces and enhancing its practicality during driving.

[0025] As shown in Figures 1-4, the hollow weight-reducing groove 13 is located at the center of the main body 1.

A rear shock absorber mounting part 10 is installed on one side surface of the main body 1, and a rear stabilizer mounting part 9 is installed on one side surface of the main body 1. The design of the drainage holes 7 can ensure that residual water is removed in time after the vehicle operates in a water-filled environment, avoiding damage to the spring pad mounting surface 8 and the car spring components.

[0028] As shown in Figures 1-4, the rear shock absorber mounting component 10 is fixedly installed on one side surface of the main body 1, and the rear stabilizer mounting component 9 is fixedly installed on one side surface of the main body 1. The surface of the rear shock absorber mounting component 10 has a rear shock absorber mounting hole 12, and the surface of the rear stabilizer mounting component 9 has a rear stabilizer bar mounting hole 11. A front liner mounting component 16 is provided on one side of the main body 1, and the surface of the front liner mounting component 16 has a front liner mounting hole 3.
