As defined in Wikipedia, aramid fibers are a class of strong, heat-resistant synthetic fibers. They are used in 5 aerospace and military applications for ballistic quality body armor fabric and ballistic composites, bicycle tires and as a replacement for asbestos. The name is a guide to "aromatic polyamide". They are fibers in which chain molecules are highly oriented along the geometric axis of the fiber, so chemical bond strength can be exploited.

A definition for aramid fiber is a fabricated fiber in which the fiber-forming substance is a long chain synthetic polyamide in which at least 85% of the amide bonds (-CO-NH-) are attached directly to two. aromatic rings.

The above list is not exhaustive and there are other similar fibers. which may be used in the invention. These fibers may expand as the battery, such as a lithium-ion polymer battery, expand over time or contract.

In more detail, Kevlar is preferred. Kevlar is the trademark for a para-aramid synthetic fiber related to other aramids such as Nomex, Heracron and Technora. Developed at DuPont in 1965, this high strength material was first commercially used in the early 70's as a replacement for steel in racing tires. Typically it is spun into strings or cloths that can be used as such or as an ingredient in the composite material components. Paraaramides, such as para-aramid fibers such as Kevlar and Twaron, provide attractive properties such as good weight resistance properties, high Young modulus, high toughness, small deformation and small elongation at break (-3.5%).

Currently, Kevlar has many applications, ranging from bicycle tires and racing sails to body frame because of its high tensile strength ratio of 25 to weight; by this measure it can be approximately five times stronger than steel on an equal weight basis. When used as a woven material, it is suitable for mooring lines and other applications. A similar fiber called Twaron with a

The similar chemical structure was developed by Akzo in the 1970s. Commercial production began in 1986 and Twaron is now manufactured by Teijin.

User interface 62 may include a 25 touch screen monitor 64 connected to the front housing 34. Users want touch screen monitors to operate electronic devices. Mobile electronic device 10 may vary widely, as previously detailed, and a mobile phone, wireless computing device and

3 0 tablet are preferred use cases. E. A mobile electronic device with enhanced shock absorber

A mobile electronic device 10 with improved impact absorber is disclosed. Device 10 may include: a housing 150 including a front housing 34 and a rear housing 86 and a user interface 62, the rear housing 86 including an impact absorber 210 located on an outermost portion of the rear housing 86. Beneficially , the impact absorber may provide improved impact relief, as shown in Figure 13. Impact absorber 210 may allow a mobile electronic device to sustain an impact and alleviate damage to housing 150 and associated components therein.

The impact absorber 210 is located at at least

at least three walls for better impact resistance in at least three locations, such as at least each sidewall and a lower wall as shown in figures 2 and 3. Preferably, the impact absorber 210 20 is located around the entire outer portion 212 for better impact relief. Beneficially, an impact absorber 210 located on the outer portion 212, for example, the more lateral portions and the upper and lower portions, may allow a mobile electronic device 25 to sustain a modest impact free of permanent damage to the housing and components therein.

Impact absorber 210 includes a shock absorber portion 222 located at an outermost portion 212 of the impact absorber. The location of the portion of

3 Damper 222 is strategically located to receive most impacts.

Impact absorber 210 comprises a resilient and flexible material. The resilient and flexible material may include a material substantially capable of withstanding the harsh environment to which it will be exposed in normal use, such as a plastic, and preferably a polycarbonate, glass filled polycarbonate and so on, which has desirable characteristics. which allow it to flex under modest impacts without permanent deformation, be durable, scratch resistant and flexible and impact resilient.

As illustrated in Fig. 13, a sectional view of the impact absorber 210 is generally U-shaped and is configured to allow a lateral lateral path 15 along an X direction along the X-axis 224. The generally U-shaped configuration U includes a damper portion 222 on a vertical member and a barrier 228 on a second vertical member 230, and is configured to allow a boundary lateral path 232 (in dashed line) parallel to a horizontal member 234.

For example, in the event of a first intermediate impact or fall, the impact absorber 210 is configured to allow a boundary lateral path 232 along an X direction parallel to the X 25 224 axis, absorbing much of the impact without permanent deformation. . Boundary side path 232 is defined by barrier 228 by contacting a frame 12 in housing 150.

In the event of a second, more severe intermediate impact than the first, shock absorber 222 receives a

The impact and the generally U-shaped impact absorber 210 moves laterally until the barrier 228 contacts the frame 12. The impact absorber 210 absorbs some of the impact and transfers some of the impact to the frame 12. Preferred embodiment, the frame 12 is made of a metallic material and can withstand a certain limiting impact. This impact can occur without permanent structural damage to the frame 12 and impact absorber 210, up to a certain limit based on the severity of the impact.

In one embodiment, the surface opposite the damper 10 222, defined as the upper and inner periphery 84 of the rear housing 86, is free of contact with a flange 236 of the front housing 34. For example, in the event of an intermediate impact, the absorber The impact device 210 is configured to allow a limit lateral travel and the outer and lower periphery 82 of the front housing 34 and flange 236 do not contact the upper and inner periphery 84 of the rear housing 86, due to span 98, thus protecting the user interface. .

The housing 150 includes a frame 12 comprising

2 0 a selected metallic material such that it can withstand

a certain limiting impact and thus protect many components in the housing 150.

In a preferred embodiment, the shock absorber 210 includes a first stage action configured to allow limiting lateral movement of its original at rest under an impact of the damper 246, shown as first stage position 240 in FIG. 13 and impact absorber 210 then returns back to its original in the rest position, whereby the shock absorber

Impact absorber 210 absorbs or retains a substantial portion of the impact force. In the event of an impact on the most severe damper at 246, the shock absorber 210 includes a second stage action or position 242 configured to allow lateral movement with the impact of the shock absorber shock absorber 246 from its original position, lateral movement is defined by a barrier portion 228 and then impact absorber 210 returns back to its original in the resting position, whereby impact absorber 210 transfers a substantial portion of the impact force through the portion of the impactor. barrier 228 for frame 12. Span 238 allows lateral movement. And, the impact absorber 210 substantially isolates the front cover 34 with the impact of the shock absorber 246, due to the gap 88 and due to non-contact with the front cover flange 236.

In Figure 13, the rear housing 86 includes a trim module 98 located adjacent an outer periphery 94 of the rear housing 86. The trim module 98 helps to reinforce a mobile electronic device against impacts. The trim module 98 may comprise a generally rectangular dimension for reinforcing the mobile electronic device.

The frame 12 is connected to a printed circuit board 28, defining a reservoir area 48 configured to receive the reservoir components. Reservoir components 48 may include chips, shielded chips, and so on on a circuit board and a battery. Impact absorber 210 and frame 12 help protect these components from certain impacts.

3 0 Many details of frame 12 have been previously detailed. Advantageously, this structure helps to provide a small profile mobile electronic device with improved impact resistance.

User interface 62 includes a 5-touch screen monitor 64 attached to the front housing 34. Users like to use 64 touch-screen monitors, and producing the impact-resistant shock absorber 210 can help protect the device. 10
