Description

Electronic equipment and shell assembly thereof

Technical Field

The invention relates to the technical field of key support structures in electronic equipment, in particular to electronic equipment and a shell assembly thereof.

Background

The existing intelligent watch has complete functions, and functional devices such as a microphone, two keys, a loudspeaker, a barometer and the like are basically distributed on the side edge of a product, and in the mutual combination process, the fastening structure of two unilateral screws is minimum.

In the prior art, the layout of the screws is relatively conservative, the number of the screws of the product is large, the reliability is excellent, and particularly, the screws are fixed beside a stress position, which is particularly important. The disadvantages are as follows: the screw layout occupies layout space of other structures, and has high requirements on the integration level of devices or the appearance space of products.

In the conventional technology, a design of two screws is also adopted, the key support is a Metal Injection Molding (MIM) piece (the wall thickness of the key support is not uniform and only injection Molding can be adopted) which is a Molding method for injecting a plasticizing mixture of Metal powder and a binder thereof into a mold, and the key support and the hole surface of the middle frame screw are matched into an inclined surface. The biggest problem is that the hand feeling sizes of the keys are large, if the sizes of the keys cannot be unified, the situation that the tolerance of supplied materials is small cannot be guaranteed, and materials with the size being out of tolerance cannot be effectively removed, so that the hand feeling is poor and high after the keys are assembled. Secondly, the size of the inclined plane can not be directly measured in the CNC machining process, the machining tolerance of the inclined plane is large, and therefore materials with poor hand feeling in subsequent assembly home products can not be intensively repaired (the defective products comprise two states of key virtual positions and key top dead states, and two schemes are needed for repair). Secondly, the key of the scheme is directly formed by metal injection molding, the strength of the bracket is not good enough, and the cost is high.
