Abstract

The present invention provides a base, including a base body with a rotating shaft arranged on the back, and a support frame with an axis hole arranged on the base body. The support frame can support the base body by coupling the axis hole and the rotating shaft. If a heavy external force is applied to the base body when the base body is supported, the axis hole will be disengaged from the rotating shaft, so that the support frame and the base body are separated, so as to prevent the support frame from being broken due to excessive external force. This base can be used as a charging base for a personal digital assistant (PDA).

Description

Base that can be separated from the support frame when subjected to heavy external forces

technical field

The present invention relates to a base, and in particular to a base with a supporting frame.

Background technique

In recent years, due to the increasingly mature development of electronics and information technology, portable electronic devices have gradually been widely used by modern people. These portable electronic devices not only promote the convenience of personal information processing, but also bring about economic activities that use notebook computers (notebooks) and personal digital assistants (personal digital assistants, PDAs) as sales channels.

For example, personal digital assistants are easy to carry because they are light, thin, short, and small, and can be used anytime and anywhere. A general personal digital assistant usually has a charging stand for placing the personal digital assistant and charging it. The charging stand not only provides the personal digital assistant with convenient charging, but also enables the personal digital assistant to continue to be used during the charging process.

In order to achieve the purpose of being able to be charged and that the personal digital assistant can still be used during the charging process, usually the charging stand of the personal digital assistant is provided with a support frame on its back to prop up the charging stand body, so that The charging stand can be conveniently used. Generally speaking, the combination of the charging base body and its supporting frame is mostly based on the coupling of the shaft hole and the rotating shaft on it, but the purpose of the shaft hole and the rotating shaft is only to enable the supporting frame to effectively support the charging base body. When a heavy external force is exerted on the body of the charging stand, the coupling part formed by the supporting frame or the shaft hole and the rotating shaft may cause fracture, which is unavoidable.

Please refer to FIG. 1A , which shows a schematic diagram of a base with a traditional support frame. The base 100 is, for example, a charging stand for a personal digital assistant, including a base body 110 and a support frame 120. By combining the base body 110 and the support frame 120, the base body 110 can be propped up to facilitate personal digital assistants. Charging of the assistant and continued use of the personal digital assistant in the charging state. If the user continues to use the PDA while it is charging (such as using a stylus to select a menu on the screen), the base body 110 will definitely feel the external force F exerted by the user, as shown in the figure. Under normal operation, the external force F should not be too large, and the support frame 120 can still bear it; but if the user accidentally presses the base body 110, the support frame 120 is likely to be broken and damaged. People say this A strong external force capable of destroying the base 100 is a heavy external force. When the base 100 is damaged by a heavy external force, the broken part may be at the center of the support frame 120 (please refer to FIG. 1B) or at the end (please refer to FIG. 1C). As for where the broken part is located, it depends on where the material is located. The destructive stress at the position is the largest, but in any case, the structural reaction under the heavy external force ends in failure, and the support frame 120 cannot continue to be used.

As can be seen from the above, the traditional base with a support frame has the following disadvantages:

1. If the support frame is broken by a heavy external force, it cannot continue to be used, causing losses to users.

2. The panel or buttons of the personal digital assistant are easily damaged by excessive external force without warning: if the base is a charging stand for a personal digital assistant, and if the support frame or coupling part is broken due to excessive external force, And when this excessive external force may be an external force acting on the panel or keys of the personal digital assistant, the damage to the personal digital assistant caused by the external force without warning will be huge.

3. The breakage of the support frame is also equivalent to the damage of the entire base: if the entire base needs to be replaced only because of the breakage of the support frame, it will be a serious waste of resources.

Contents of the invention

In view of this, the purpose of the present invention is to provide a base that can be separated from the support frame when subjected to a heavy external force. The purpose is as follows:

1. Even though the base body is subjected to a heavy external force, it will not cause fracture and damage to the supporting frame or the coupling part.

2. If the base is a charging stand for a personal digital assistant, it can protect the panel or keys of the personal digital assistant from being damaged by excessive external force without warning.

3. Save the cost of replacing the entire base due to the breakage of the support frame or the coupling part.

According to the above-mentioned purposes, the present invention proposes a base that can be separated from the support frame when subjected to a heavy external force, and its structural features are briefly described as follows:

A pedestal, comprising a pedestal body with a rotating shaft on its back, and a support frame with a shaft hole on it, through the coupling of the shaft hole and the rotating shaft, the support frame can support the base body, and If a heavy external force is applied to the base body when the base body is propped up, the shaft hole will be separated from the rotating shaft, so that the support frame will be separated from the base, so as to prevent the support frame from being broken due to excessive external force. The base can be used as a charging stand for a personal digital assistant (PDA).

Detailed ways

The base provided by the present invention can be separated from the supporting frame when subjected to heavy external force. The breakage of the supporting frame or the coupling portion of the supporting frame and the charging stand body makes the supporting frame unusable, and the panel and keys of the personal digital assistant may be damaged under the action of such an excessive external force. Therefore, if the shaft hole of the coupling part can be disengaged from the rotating shaft before the support frame or the coupling part reaches the breaking stress when the body of the charging stand bears a heavy external force, not only can the support frame not be damaged and fractured, but After the supporting frame is separated from the main body of the charging stand, it can still be reassembled back to the original state to continue to use, and it can also make the surface electrode or the button of the personal digital assistant be connected to the charging stand before it is likely to be subjected to excessive external force. The main body is separated, which is also an early warning protection device to prevent personal digital assistants from being damaged. Its specific implementation method will be described below.

Please refer to FIG. 2A , which is a schematic view before assembly of the base body and the support frame provided according to a preferred embodiment of the present invention. The base 200 is, for example, a charging stand for a personal digital assistant, and includes a base body 210 and a support frame 220. The back of the base body 210 is provided with a rotating shaft 215, and the support frame 220 is provided with a shaft hole 225. The base body 210 After being coupled with the support frame 220 through the shaft 215 and the shaft hole 225 arranged thereon, the assembled base body 210 and the support frame 220 shown in FIG. 2B are assembled. FIG. 2C shows that the support frame 220 will The situation that the base body 210 is propped up.

Next, please refer to FIG. 3 , which shows a schematic diagram of separation of the support frame from the base body when the base body is subjected to a heavy external force. If the support frame 220 supports the base body 210 and is subjected to a heavy external force Fs, the rotating shaft and the shaft hole will be separated from each other, that is, the base body 210 will be separated from the support frame 220 . With proper design of the shaft and the shaft hole, the shaft and the shaft hole can be disengaged before the external force borne by the base body 210 is not enough to cause the support frame 220 to break (for example, the coupling depth of the shaft and the shaft hole is short, and the external force When heavy pressure causes the rotating shaft to deform and separate from the shaft hole), it has the function of protecting the support frame 220, and after the base body 210 is separated from the support frame 220, the support frame 220 that is not broken and damaged can still be reattached to the base body 210 to restore the supporting function of the original support frame 210. Another advantage of this design is that when the PDA panel or keys on the base body 210 are subjected to excessive external force sufficient to damage them, the support frame 220 is separated from the base body 210, which also has protection. Functionality of personal digital assistants from being compromised.
