Description

Waterproof key, electronic equipment and assembling method of waterproof key

Technical Field

The invention relates to the technical field of key structures, in particular to a waterproof key, electronic equipment and an assembling method of the waterproof key.

Background

The key is used as one of interfaces of human-computer interaction, can assist a user to realize quick input operation on an electronic product, and is widely used on electronic products such as a POS (point of sale) machine, a PDA (personal digital assistant), a PAD (PAD application), a mobile phone, a notebook computer and the like.

With the continuous increase of the consumption level, the waterproof function of electronic products is becoming a concern of consumers. If the electronic product falls into water in the using process or is used under the condition of hand wetting, water enters the electronic product from the key positions, so that a circuit board in the electronic product is short-circuited, and finally the electronic product is failed or directly scrapped, thereby seriously influencing the user experience of the electronic product.

Therefore, in order to improve the waterproof performance of electronic products, the existing electronic products usually have waterproof design on the keys, and the keys are called waterproof keys and can prevent water from entering the electronic products.

The design of waterproof button commonly used at present has two kinds, and the first kind is adorned the casing through the mode of back of the body dress after assembling key cap and button flexible glue, and the second kind is adorned the casing through the mode of just adorning after assembling key cap and button flexible glue. In the first waterproof key design, please refer to fig. 1, the key is assembled from the back of the housing, and after the two sides of the soft key rubber are connected with the housing buckle, a dispensing slot is specially designed for injecting a dispensing solution to connect the soft key rubber and the housing in a sealing manner, so that the whole waterproof structure needs to occupy a larger space than the appearance of the key to meet the structural requirement, and the first waterproof key design is not only poor in space utilization rate but also not beneficial to ID modeling. Referring to fig. 2, in the second waterproof key design, since the key is assembled from the front of the housing, the joint between the soft rubber of the key and the housing cannot be glued and waterproof, but an interference fit manner is adopted, although this manner does not have the problem of large occupied space of the first design, the cost is that the waterproof performance is far inferior to that of glue and waterproof, and can only reach below IPX5, and after the key is assembled to the housing, structures such as a pressing plate need to be added on the front of the housing to limit the key from being separated, so that the structural space utilization rate is poor and the integrity of the appearance is damaged.

Therefore, there is a need for a new waterproof key design.
