Abstract
Description
Technical Field
[0001] This utility model relates to the field of automobile manufacturing, specifically to an inductor welding structure that can enhance the impact resistance of EPS. Background Technology
[0002] In the industry, inductors are typically soldered using a bump soldering method. This method results in a small contact area at the solder joints, as shown below. Figure 1-2 As shown, the existing inductor bump connection welding structure has a limited contact area, consisting only of the protruding surface of the bump. This results in insufficient impact resistance after welding and a risk of solder joint detachment. Utility Model Content
[0003] To address the aforementioned problems, this invention provides an inductor welding structure that enhances the impact resistance of EPS (expanded power supplies). This welding structure improves the impact resistance of the solder joints and effectively prevents detachment and failure. The specific technical solution is as follows:
[0004] An inductor welding structure that can enhance the impact resistance of EPS includes a contact plate PLUS that connects to the inductor, which is configured as a flat plate. The overall bending distance of the contact plate PLUS is forward, and the bending angle is set to 90°±1°.
[0005] Furthermore, the gap between the contact plate PLUS and the inductor choke is 2-3mm.
[0006] This invention eliminates the protruding bulges of the original contact plates Plus and Plus2, replacing them with a flat plate structure. This allows for a forward bending distance while maintaining the same bending angle (90°±1°), eliminating potential welding pre-stress. Before and after welding, the gap between Plus and the inductor choke remains unchanged, as does the bending angle. Through structural optimization, the impact resistance of the weld joints is improved, preventing detachment and failure. Attached Figure Description

[0011] 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.
[0012] like Figure 3-4 As shown, an inductor welding structure that enhances the impact resistance of EPS includes a contact plate PLUS connected to the inductor, which is configured as a flat plate. The overall bending distance of the contact plate PLUS is forward, and the bending angle is set to 90°±1°. The gap between the contact plate PLUS and the inductor choke is 2-3mm.
[0013] Compared with existing technologies, this invention eliminates the protrusions of the original contact plates Plus and Plus2, replacing them with a flat plate structure; this allows the overall bending distance to be forward while maintaining the same bending angle (90°±1°), eliminating potential welding prestress; the gap between Plus and the inductor choke remains unchanged before and after welding, and the bending angle remains the same. Through structural optimization, the impact resistance of the weld joint is improved, preventing detachment failure.
[0014] The preferred embodiments of this patent have been described in detail above. However, this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this patent.
