Description

Electronic device and waterproof structure thereof

Technical Field

The utility model relates to an electronic device and a waterproof structure thereof.

Background

The keyboard and the touch pad of the notebook computer are the most commonly used input devices, the keyboard is used for inputting characters, symbols and the like, and the touch pad can be used for a user to slide on the touch pad by fingers so as to operate a mouse.

In order to connect a keyboard to a motherboard (main board) of a notebook computer, a flexible board (flexible circuit board) is generally used to pass through a through hole of a bracket under the keyboard, and one end of the flexible board has a connector that can be connected to the motherboard, so as to transmit signals between the motherboard and the keyboard. In addition, in order to prevent liquid such as water from entering the notebook computer body through the through hole of the bracket, a waterproof sponge (sponge) is conventionally arranged at the through hole of the bracket, and only a slit is reserved for the waterproof sponge to pass through by the soft board. However, since the waterproof sponge still has slits, the waterproof effect is not optimal, and particularly when the amount of liquid such as water is large, there is a risk that the liquid such as water flows into the body of the notebook computer.

Detailed Description

Referring to fig. 1, fig. 2A and fig. 2B, fig. 1 is a schematic diagram of an electronic device 100 according to an embodiment of the utility model, and fig. 2A and fig. 2B are an exploded view and a partial cross-sectional view of an internal structure of the electronic device 100 according to an embodiment of the utility model. In order to make the features of the present disclosure more obvious, the electronic device 100 of fig. 1, 2A and 2B only shows the keyboard 110 and the touch pad 111 of the notebook computer, and omits the display panel. Since the display panel is not an important point in this case, a description of this portion is omitted. The keyboard soft board is improved aiming at the problem that the conventional keyboard soft board passes through the through hole of the bracket below the keyboard so as to achieve better waterproof effect, but the keyboard soft board is not limited to being used on a notebook computer and can also be used on other handheld electronic devices.

The electronic device 100 includes a keyboard 110, a bracket 120, and a motherboard 130. The keyboard 110 has a plurality of keys 112, a flexible printed circuit 116, and a first electrical connection device 118, wherein the keys 112 are disposed on one side (e.g. upper side) of the flexible printed circuit 116, and the first electrical connection device 118 is disposed on the other side (e.g. lower side) of the flexible printed circuit 116. The bracket 120 is disposed between the keyboard 110 and the motherboard 130, and the bracket 120 has at least one opening 121 (a plurality of the openings are shown) and a waterproof structure 124 disposed around the opening 121. The main board 130 includes a second electrical connection device 132, and the first and second electrical connection devices 118, 132 are connected to each other through the opening 121 (see fig. 2B).

As shown in fig. 1, the keys 112 of the keyboard 110 are used for being pressed by a user to input characters, symbols, etc., and the touch pad 111 is used for a user to slide on the touch pad with fingers to operate the mouse. In addition, the keys 112 of the keyboard 110 are disposed on the flexible circuit board 116, and are electrically connected to the motherboard 130 via the flexible circuit board 116. In detail, the key 112 has a key cap 113, a scissor structure (supporting structure) 114, and an elastic body 115, wherein the key cap 113 is disposed on the scissor structure 114, the elastic body 115 is disposed in the scissor structure 114 and is abutted between the key cap 113 and the flexible circuit board 116, and when the key cap 113 is pressed, the key cap 113 moves downward to press the elastic body 115, so that the elastic body 115 is in a pressed state and the upper and lower circuit layers of the flexible circuit board 116 are conducted to generate a pressing signal. The pressing signal can be transmitted to the motherboard 130 via the flexible circuit board 116, and the controller on the motherboard 130 generates a corresponding signal.

The keys 112 of the keyboard 110 may be of other types, not limited to a scissors type.

As shown in fig. 2A, the bracket 120 is disposed below the keyboard 110, and the bracket 120 is provided with a recess 122, for example, the recess 122 is formed by stamping, for example, to accommodate the first electrical connection device 118. In addition, the bracket 120 forms an opening 121 at the bottom of the recess 122, and the opening 121 penetrates the bracket 120 and exposes the second electrical connection device 132. As shown in fig. 2B, the waterproof structure 124 is disposed around the opening 121, for example, and the first and second electrical connection devices 118 and 132 can be connected to each other through the opening 121 and press the waterproof structure 124, so that the periphery of the opening 121 is sealed by the waterproof structure 124 to achieve the waterproof effect.

In one embodiment, the first electrical connection device 118 is, for example, a female connector, and the second electrical connection device 132 is, for example, a male connector, and the terminal (pin 133) of the second electrical connection device 132 is connectable with the terminal 119 of the first electrical connection device 118 through the opening 121 of the bracket 120. The second electrical connection device 132 is, for example, a plug and play pin connection device, which may be a conductive device such as a spring pin (pogo pin) for providing a function such as signal connection or power connection.

Referring to fig. 3A and 3B, schematic diagrams of an electrical connection device with a waterproof structure 124 according to an embodiment of the utility model are shown. The waterproof structure 124 is used in an electronic device 100, such as a notebook computer or other products, the electronic device 100 has a first electrical connection device 118 and a second electrical connection device 132, the waterproof structure 124 is disposed on a bracket 120, the bracket 120 has an opening 121, and the waterproof structure 124 is disposed around the opening 121, wherein the first and second electrical connection devices 118, 132 are connected to each other through the opening 121. The waterproof structure 124 has, for example, at least one or a plurality of through holes 123 aligned up and down with the positions of the openings 121.

In fig. 3A, the first electrical connection device 118 is disposed on one side of the flexible circuit board 116 (see fig. 2B), for example, the first electrical connection device 118 has an outer frame 117, and the outer frame 117 can be pressed against the waterproof structure 124, so as to more effectively prevent liquid such as water from overflowing. The second electrical connection device 132 is disposed on the main board 130, for example, and the second electrical connection device 132 is composed of a pin 133 (plunger), a spring 134 (spring), and a tube 135 (tube). The pin 133 is disposed at one end of the tube 135, the spring 134 is disposed in the tube 135, and the pin 133 is pushed by the elastic force of the spring 134 and partially protrudes out of the tube 135. In fig. 3B, when the first and second electrical connectors 118, 132 are connected to each other, the pin 133 pushes against the spring 134 to retract into the tube 135, and the waterproof structure 124 seals around the opening 121 to prevent liquid such as water from overflowing.

In one embodiment, the waterproof structure 124 is a sealing material such as sponge, foam, or other material. The waterproof structure 124 may be attached around the opening 121 with glue or tape.

Referring to fig. 4, a schematic top view of a waterproof structure 124 according to an embodiment of the utility model is shown. The waterproof structure 124 is, for example, a strip shape, the through hole 123 is wrapped around the pin 133, and the pins 133 of the second electrical connection device 132 can respectively protrude from the through hole 123 for electrical connection.

Compared with the traditional waterproof sponge in which a slit is reserved for a soft board to pass through, the waterproof structure is of a sealing type, and the waterproof structure is extruded by the first electric connecting device to effectively prevent liquid such as water from overflowing into the electronic device, so that a higher waterproof grade is achieved, and the waterproof performance of the electronic device is improved.
