Description

A portable electronic device with replaceable keyboard

technical field

The invention relates to a structure of a portable electronic device, in particular to a structure of a portable electronic device with a replaceable keyboard.

Background technique

With the continuous development and progress of technology and information today, computer equipment has become quite common and has become one of the indispensable electronic products in the daily life or work of the whole people. It is undeniable that computer devices have gradually begun to change human life. Habit. Currently, the computer equipment seen on the market, whether it is a desktop computer (Personal Computer, PC) or a notebook computer (Notebook), must use external computer peripheral devices such as display screens, projectors, printers, keyboards, mice, etc. Execute the preset function of the window interface of the computer device.

Taking notebook computers as an example, the keyboard has been widely used in the interface control of notebook computers and has become an inseparable hardware peripheral device. Generally, the keyboards used in existing notebook computers are embedded in the main body of the computer during the manufacturing process. In the accommodating space, and form an integrally formed host structure. However, the keyboard structure still has a certain service life, especially when the user is using a notebook computer, the keyboard is often prone to contamination due to dust from the external environment, dirt and grease from the user's hands. It is difficult to recognize the text marked on it due to damage, and even cause the problem that the keycap is difficult to be pressed or cannot bounce back to its original position after being pressed; or, the user accidentally spills drinks, water and other liquids placed on the keyboard on the keyboard above, causing electrical damage to the keyboard, which will accelerate the shortening of the service life of the key structure.

Since the keyboard of the notebook computer is an integral module structure, and is embedded in the host body and is not easy to take out, when the keyboard has mechanical failure or electrical damage, the only option is to send the entire notebook computer to The manufacturer repairs or replaces the keyboard with a brand new one, which will cause the trouble and trouble for the user to have no computer available for a short period of time. If the user can replace the damaged keyboard by himself, the waiting time for repairing will be avoided.

In addition, the text printed on the existing keyboard has been pre-designed and cannot be changed. If the user needs to use a keyboard with different input fonts, an additional layer of key film must be covered on the keyboard, or the printed font on the keyboard must be removed. Finally, reprint the required font symbols one by one. The above two methods are not only too complicated and time-consuming to process, but also the tactile feeling of the button film is not good, which will cause troubles in operation for users who are not used to it.

The above-mentioned portable electronic device with replaceable keyboard is characterized in that at least one elastic member is provided on the side of the keyboard opposite to the accommodating slot.

The present invention also provides a portable electronic device with a replaceable keyboard, which is characterized in that it includes:

A host body, the host body has an accommodating slot and two opposite slide slots, and the accommodating slot is provided with a circuit substrate, and a plurality of electrical contacts are arranged on the circuit substrate, and a card is arranged in the slide slot hook and a spring that normally pushes against the hook; and

A keyboard is arranged in the accommodating groove in a detachable group relationship, the keyboard has a plurality of keys, and the keys are provided with a plurality of trigger pins corresponding to the electrical contacts, so as to trigger the electrical contacts to output a preset According to the signal, two opposite sides of the keyboard are respectively provided with a button hole for interlocking with the buckle member, and a plurality of elastic members are arranged on the side of the keyboard opposite to the accommodating groove.

The effect of the present invention is that the keyboard can be arbitrarily assembled or disassembled from the main body through the matching of the buckle parts arranged on the main body and the button holes on the side of the keyboard, so that the user can easily and quickly The purpose of replacing the keyboard.

The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments, but not as a limitation of the present invention.
