Title:
ULTRASONIC WELDING AND SNAP-FITTING STRUCTURE AND ULTRASONIC WELDED HOUSING
Document Type and Number:
WIPO Patent Application WO/2024/060664
Kind Code:
A1
Abstract:
Disclosed in the present invention are an ultrasonic welding and snap-fitting structure and an ultrasonic welded housing. The ultrasonic welding and snap-fitting structure comprises: first shell snap-fits, provided on a first shell; and second shell snap-fits, provided on a second shell and adapted to be snap-fitted to the first shell snap-fits. At least one of the first shell snap-fit and the second shell snap-fit comprises at least two snap-fits which are spaced in the assembling direction of the first shell and the second shell. Before ultrasonic welding, one corresponding first shell snap-fit is tightly snap-fitted to a second shell snap-fit, so that the first shell is tightly snap-fitted to the second shell during ultrasonic welding, thereby reducing the probability of separation of the first shell and the second shell during ultrasonic welding, and improving the efficiency and quality of ultrasonic welding. After ultrasonic welding, the other corresponding first shell snap-fit is tightly snap-fitted to the second shell snap-fit, thereby improving the connection strength after ultrasonic welding, i.e., improving the connection strength of the first shell and the second shell.
