[0004] However, the following problems were found in the implementation of the relevant technologies: Although the existing equipment has improved its impact resistance through the cross-set structure, the structure used to strengthen itself is relatively weak, and the improvement in impact resistance is not significant enough. Utility Model Content

[0005] To address the problems mentioned in the background art, this utility model provides an impact-resistant control arm with the advantages of a more robust structure for strengthening itself and significantly improved impact resistance.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an impact-resistant control arm, comprising a reinforcing strip, wherein the front and rear ends of the reinforcing strip are respectively connected to a ball pin seat and a front bushing sleeve, and a control arm body is fixedly sleeved between the outer walls of the reinforcing strip, the ball pin seat and the front bushing sleeve; a plurality of first reinforcing posts are fixedly inserted side by side at the top of the reinforcing strip, and a plurality of second reinforcing posts are fixedly inserted side by side at the side walls of the reinforcing strip, wherein the first reinforcing posts and the second reinforcing posts are staggered; a connecting block is connected to the right end of the control arm body, and a rear bushing sleeve is integrally formed at the right end of the connecting block.

[0007] Preferably, the front and rear ends of the connecting block are integrally formed with reinforcing plates, and the corresponding sides of the reinforcing plates and the control arm body are screwed together with fixing screws.

[0008] Preferably, a washer is fitted on the side wall of the fixing screw, and the washer is supported between the head of the fixing screw and the corresponding side of the reinforcing plate.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figures 1 to 3As shown, this utility model provides an impact-resistant control arm, including a reinforcing strip 1. The front and rear ends of the reinforcing strip 1 are respectively welded with ball pin seats 3 and front bushing sleeves 2. The welding connection method makes the installation more stable. The ball pin seats 3 and front bushing sleeves 2 are used to connect with the external structure. The control arm body 6 is fixedly sleeved between the outer walls of the reinforcing strip 1, the ball pin seats 3 and the front bushing sleeves 2. The reinforcing strip 1 serves as the main structure. Improving its impact resistance can increase the overall impact resistance of the equipment. Multiple first reinforcing columns 4 are fixedly inserted side by side at the top of the reinforcing strip 1, which can improve the longitudinal impact resistance of the equipment. Multiple second reinforcing columns 5 are fixedly inserted side by side at the side walls of the reinforcing strip 1, which can improve the lateral impact resistance of the equipment. The first reinforcing columns 4 and second reinforcing columns 5 are staggered. The reasonable distribution of the first reinforcing columns 4 and second reinforcing columns 5 significantly improves the overall impact resistance. A connecting block 7 is welded to the right end of the control arm body 6, and a rear bushing sleeve 8 is integrally formed at the right end of the connecting block 7 for connecting with the external structure.

[0021] Specifically, the front and rear ends of the connecting block 7 are integrally formed with reinforcing plates 9, and the reinforcing plates 9 and the corresponding sides of the control arm body 6 are screwed together with fixing screws 10. This structure enables the connecting block 7 to be more stably connected to the corresponding sides of the control arm body 6, thereby improving the impact resistance of the rear bushing sleeve 8.

[0022] Furthermore, a washer 11 is fitted on the side wall of the fixing screw 10, and the washer 11 is supported between the head of the fixing screw 10 and the corresponding side of the reinforcing plate 9, which can prevent the fixing screw 10 from being tightened too much and causing wear, and avoid inconvenience in subsequent disassembly.

[0023] Furthermore, the connection block 7 and the reinforcing plate 9, as well as the connection block 7 and the rear bushing sleeve 8, are both die-cast integral structures. The die-cast integral structure has high structural strength and excellent impact resistance.

[0024] It is worth noting that the ball pin seat 3 is fitted with a first reinforcing sleeve 13 on its outer side, and the first reinforcing sleeve 13 is connected to the front end of the control arm body 6, which can improve the impact resistance of the ball pin seat 3 and prevent the connection with the external structure from becoming loose.

[0025] It is worth noting that a second reinforcing sleeve 12 is fitted on the outer side of the front bushing sleeve 2, and the second reinforcing sleeve 12 is connected to the rear end of the control arm body 6, which can improve the impact resistance of the front bushing sleeve 2 and prevent the connection with the external structure from loosening.

[0026] The front, back, left, and right perspectives of this device are... Figure 1 The direction shown in the diagram is the reference.

[0027] Working principle: The device is placed as follows Figure 1After installation, the equipment is connected to the external structure through the front bushing sleeve 2, ball pin seat 3 and rear bushing sleeve 8. When subjected to impact, the multiple first reinforcing columns 4 inserted side by side at the top of the reinforcing strip 1 can improve its longitudinal impact resistance, and the multiple second reinforcing columns 5 inserted side by side on the side wall of the reinforcing strip 1 can improve its lateral impact resistance. The main reinforcing strip 1 is more robust in terms of strength, and the reasonable distribution of the first reinforcing columns 4 and the second reinforcing columns 5 further enhances the impact resistance.
