Problems solved by technology

In the prior art, waterproof keyboards are often wrapped with a waterproof film on the key surface, but the process is complicated and difficult to control, and the waterproof film is easily damaged
In addition, there is also an adhesive method to bond the keycap to the casing of the portable electronic device. However, since the keycap is generally a soft body, and the soft body is difficult to bond on the casing, the bonding effect is not good. Ideal, which will affect the waterproof and dustproof effect

Description

technical field [0001] The invention relates to a key module and a portable electronic device using the key module. Background technique [0002] With the development of wireless communication and information processing technologies, portable electronic devices such as mobile phones and personal digital assistants (PDAs) have emerged one after another, enabling consumers to fully enjoy various conveniences brought by high technology anytime, anywhere. In portable electronic devices, keys as user input terminals have become an indispensable part of portable electronic devices. [0003] The key module of the existing portable electronic device generally only includes a key cover and a key cap, and the key cap is adhered to the key cap. The keycap is an elastic body, which can be deformed under the action of external force and recover its shape after the external force is removed. The key module is sleeved in the casing hole of the portable electronic device, and a fine gap i...
