a. Field of the Invention
The invention relates to a force dispersing device.
b. Description of the Related Art
In typical product designs, internal components inside a product may suffer little or even no external forces to avoid damages by increasing the rigidity of outer components. For example, a selection of materials or supply of structural reinforcement may help to increase the rigidity. However, the increase in rigidity may correspondingly increase the volume and weight to frustrate the purpose of fabricating a light and thin product. Further, a bubble pack having multiple independent air cells often serves as a packaging buffer, and each cell may absorb external forces relying on material expendability and air compressibility. However, the air cells are separate from each other to hardly disperse force in different directions. Therefore, a bubble pack may function as a buffer but fail to effectively disperse forces imposed thereon.
Therefore, it is desirable to provide a force dispersing device to distribute external forces over a large area within a limited space to reduce the stress imposed on and thus prevent damages to internal components.
The information disclosed in this “BACKGROUND OF THE INVENTION” section is only for enhancement understanding of the background of the described technology, and therefore it may contain information that does not form the prior art that is already known to a person of ordinary skill in the art. Furthermore, the information disclosed in this “BACKGROUND OF THE INVENTION” section does not mean that one or more problems to be solved by one or more embodiments of the invention were acknowledged by a person of ordinary skill in the art.
The invention provides a force dispersing device that achieves force dispersing effects.
Other objects and advantages of the invention may be further illustrated by the technical features broadly embodied and described as follows.
In order to achieve at least one or a portion of or all of the objects or other objects, one embodiment of the invention provides a force dispersing device for a display device. The display device has a casing, a backlight module and a display panel, the casing has a display opening, the backlight module is disposed in the display opening, and the display panel is disposed on the backlight module and in the display opening. The force dispersing device includes a fluid bag filled with a confined fluid and disposed between the casing and the backlight module.
In order to achieve at least one or a portion of or all of the objects or other objects, another embodiment of the invention provides a force dispersing device for dispersing a stress arisen from a stress concentration portion and imposed on at least one component inside a device. The force dispersing device includes a confined fluid pressing against the component to disperse the stress arisen from the stress concentration portion and imposed on the component. An area of the confined fluid is larger than a force exertion area on the component, and the stress concentration portion imposes the stress on the component via the force exertion area.
According to the above embodiments, since the same pressure change occurs everywhere in a confined fluid, the fluid bag disposed in a limited space is allowed to disperse the force applied thereon over a wider area to reduce the stress imposed on surrounding components. Besides, such arrangement may reduce the stress arisen from the stress concentration portion and imposed on components inside a device to prevent mechanical damage to the internal components. Further, the fluid bag is easy to adapt to different environments by changing its shape, thickness or distribution to function as a force dispersion structure flexible in use.
Other objectives, features and advantages of the invention will be further understood from the further technological features disclosed by the embodiments of the invention wherein there are shown and described preferred embodiments of this invention, simply by way of illustration of modes best suited to carry out the invention.
In the following detailed description of the preferred embodiments, reference is made to the accompanying drawings which form a part hereof, and in which are shown by way of illustration specific embodiments in which the invention may be practiced. In this regard, directional terminology, such as “top,” “bottom,” “front,” “back,” etc., is used with reference to the orientation of the Figure(s) being described. The components of the invention can be positioned in a number of different orientations. As such, the directional terminology is used for purposes of illustration and is in no way limiting. On the other hand, the drawings are only schematic and the sizes of components may be exaggerated for clarity. It is to be understood that other embodiments may be utilized and structural changes may be made without departing from the scope of the invention. Also, it is to be understood that the phraseology and terminology used herein are for the purpose of description and should not be regarded as limiting. The use of “including,” “comprising,” or “having” and variations thereof herein is meant to encompass the items listed thereafter and equivalents thereof as well as additional items. Unless limited otherwise, the terms “connected,” “coupled,” and “mounted” and variations thereof herein are used broadly and encompass direct and indirect connections, couplings, and mountings. Similarly, the terms “facing,” “faces” and variations thereof herein are used broadly and encompass direct and indirect facing, and “adjacent to” and variations thereof herein are used broadly and encompass directly and indirectly “adjacent to”. Therefore, the description of “A” component facing “B” component herein may contain the situations that “A” component directly faces “B” component or one or more additional components are between “A” component and “B” component. Also, the description of “A” component “adjacent to” “B” component herein may contain the situations that “A” component is directly “adjacent to” “B” component or one or more additional components are between “A” component and “B” component. Accordingly, the drawings and descriptions will be regarded as illustrative in nature and not as restrictive.
In this embodiment, the force dispersing device 20 may include a fluid bag filled with a confined fluid, and the fluid bag 22 may be disposed between the casing 12 and the backlight module 14. The fluid confined in the fluid bag 22 may be, but not limited to, gas or liquid.
Referring to
Note the fluid bag is not limited to a specific configuration. In one embodiment shown in
The test results of sample products according to embodiments of the invention and conventional designs are shown in Table 1. The test conditions are described in the following. For example, an external force applied to each sample product is equal to 9 KGF, and a force dispersing device such as a fluid bag may be disposed between a backlight module and a casing (such as an A piece of a laptop computer). The casing is made of AL5052 type aluminum, and force sensors are disposed between a stress concentration portion (such as a raised portion of a keyboard) and a display panel. As shown in Table 1, a value of 3.1 KG measured by force sensors is obtained for the samples in Group 1 (without any force dispersion treatment) and Group 2 (rubber used as a buffer only), and a value of 2.4 KG measured by force sensors is obtained for the sample in Group 4 having a larger gap thickness between the backlight module and the casing. Besides, a value of 2.0 KG measured by force sensors is obtained for the sample in Group 3 where a fluid bag is disposed between the backlight module and the casing. Therefore, the design of using a fluid bag according an embodiment of the invention has enhanced force dispersing effects as compared with the design of increasing a gap between the backlight module and the casing. Further, it can be found, when comparing different gas amounts of fluid bags in Group 5, Group 6 and Group 7, a higher gas amount of a fluid bag may achieve better force dispersing effects.
According to the above embodiment, the force dispersing devices of the embodiments of the invention have at least one of the following advantages. Since the same pressure change occurs everywhere in a confined fluid, the fluid bag disposed in a limited space is allowed to disperse the force applied thereon over a wider area to reduce the stress imposed on surrounding components. Besides, such arrangement may reduce the stress arisen from the stress concentration portion and imposed on components inside a device to prevent mechanical damage to the internal components. Further, the fluid bag is easy to adapt to different environments by changing its shape, thickness or distribution to function as a force dispersion structure flexible in use.
