Abstract

The inventive solution relates to a design of mobile-carrying electronic devices (cellular phones, portable radio transmitter, electronic notebooks, personal digital assistant, smart-phone, digital photo cameras etc.). The proposed invention is illustrated by portable (mobile) phones.The inventive device provides higher reliability and longer life-time of portable electronic devices. The proposed arrangement differs from the prior art by that functional modules of a potable electronic device are divided into 2 groups, one of them comprises display modules, terminal electronics and a storage battery, the other comprises modules of a key board and/or a dialer. The first module group is housed in a sealing tight case which is inner towards the outer bag which houses the key board and/or a dialer. The inner case is placed inside the outer case with some gap for arranging shock-absorbing means there between. Functional modules of the outer and inner cases are interacted using electric, acoustic, radio or optic interfaces.Location of terminal electronics in a separate strong sealing case permits to reduce a number of movable parts and points from attracting moisture and dust via key board buttons, technologic holes, connector “windows” etc. The outer cases serves as housing (cover) for protection the functional modules arranged in the inner case. The design elements of the outer case is easily-detachable (replaceable) and cheap in cost.

Description

The technical field to which the invention relates.

The proposed solution relates to the design of mobile wearable electronic devices (mobile phones, wearable radios, electronic notebooks, personal digital assistants (PDAs, Yaiyu, Chinese computers, handheld computers), digital cameras, etc.).

Prior Art Information

Consider the proposed technical solution on the example of portable (mobile) phones. Portable phones are widely known. These include cordless phones, such as cellular phones, cordless phones, and personal communications. Typically, portable phones communicate with a remote base station, providing wireless connectivity to the subscriber. Portable phones have become a widespread form of wireless communication in the market of cordless phones and cordless phones and are rapidly finding use in new types of communication systems, such as personal communication systems (ATP).

In 2001, one of the companies engaged in statistical research determined the number of mobile phones that failed. It turned out that about three million mobile phones died under the wheels of transport, the other three million were broken by children. About ten million mobile phones were accidentally shaken out of packages and bags on asphalt or concrete. About four million phones fell from the hands of users, and seven million fell into the water. Statistics clearly show that most failures and damage are caused by falls in mobile electronic devices or the consequences of falls.

Mobile phone manufacturers seek to develop designs that are able to provide the necessary protection against falls (shock effects). However, known constructions, as a rule, develop only one key property, which makes this property convenient only for a certain circle of users.

For example, for people leading an active lifestyle, you can make a not very complicated, but very reliable phone, put it in a durable, preferably waterproof case. Such a phone, despite the high weight and higher price for a terminal with such functions, will find a buyer. For the buyer, for whom, after an unexpected fall or an accidental swim in clothes, it is better to have a large phone and without special (special) functions, but working than a small, with wide capabilities, but which has become unusable. Such devices are produced by many large manufacturers.

A number of technical solutions aimed at creating such devices are already known.

In US Pat. No. 6,092,707, published July 25, 2000, a device is described (within which a telephone is placed) fixed to a mobile vehicle (bicycle, kayak) that protects the telephone from impacts and various weather conditions.

In US patent No. 6330430, published December 11, 2001, described a cover for a mobile terminal or mobile phone that protects the device when carried.

In US patent No. 5025921, published June 25, 1991, describes a device for protecting a portable electronic device from acid vapors, acetone, toluene, etc. The device is made of a chemically inert polymeric material, such as Teflon.

The number of known devices, which are waterproof covers. They protect the devices placed in these covers from impact, water, sand, dirt. In this case, for example, the number can be dialed without removing the phone from the case. The most famous brand of such a cover is Βοχίΐ 5.0 Ωοίρΐιίη. Today, it is suitable for 90% of telephones in the cellular market. Launches the covers еоοχίΐ the firm Moylegeo Ou (Finland). This company has filed a number of applications, received patents: и8 2004/0014506 A1, publication January 22, 2004; XVO 02/03828 A1, publication January 17, 2002; HUO 03/101245 A1, publication December 11, 2003. A number of patents and applications from other companies for similar devices are known: US Patent No. 6068119, publication May 30, 2000, νθ 00/51315, publication August 31, 2000. In Japanese Application No. 07288567 a description of the water-dust cover, which closes with a zipper.

Firm Νο1 <ί; · ι released O8M phone Νο1 <; · ι 6250, which is positioned on the market as a telephone of daily use by people of various professions - from a road worker to a rural doctor. This model is a phone with built-in protection against water, dust and drops. The shock absorption is provided by elastic inserts, and membranes are provided for the microphone, speaker and buzzer. Used waterproof hermetic coating, sealed connectors, a thick display mounted on a special substrate. The antenna is made of elastic material. The body is combined from a set of plastic and rubber parts. The battery is attached to special rubber guides (see “Phone Νο1 <; · ι 6250. Description and user guide.”).

Another direction in ensuring the survivability of a mobile device is the creation of "floating" samples. The Swedish company Ετίοκκοη received US patent No. 6355374, published March 12, 2002, which describes a "floating" phone. A similar design is given in US patent No. 6326543 issued to the company ΜοΐοτοΗ, which was published on December 4, 2001. In another patent, the Swedish company τίοκκοη protects the design of a non-sinking mobile phone. On the back

- 1 007175 part of the case a float module is installed on top of the battery. As a result, the device gains buoyancy. It is believed that such a design is better than a float combined with a battery. If necessary, it can be removed, which makes the device less cumbersome (US patent No. 6355374, published March 12, 2002).

Another direction that ensures the strength of the mobile device case is the creation of special materials used for the manufacture of cases: AB8 + PC plastics and special alloys. For example, Ycschbtey Shts1toschch5 (USA) is looking for areas of widespread use of an amorphous alloy developed at the California Institute of Technology as early as 1992. This alloy is about twice as strong as titanium and is not susceptible to corrosion. In the manufacture of parts by casting the metal during the cooling is not compressed. The accuracy of casting production in this case reaches 1 micron.

There are a number of solutions aimed at ensuring the safety and operability of individual, the most important elements, by placing them in certain areas of mobile devices. For example, in US patent No. 4919624, published April 24, 1990, the battery is placed in a special section of the housing to be closed. In patent EP 0522762 B1, published September 19, 1999, the 8 card is placed in a special section and covered with a battery unit.

The closest technical solution to the proposed is Jokta 6250 phone. This phone is positioned by the company on the market as a telephone of daily use by people of various professions - from a road worker to a rural doctor. This model is a phone with built-in protection against water, dust and drops. The shock absorption is provided by elastic inserts, and membranes are provided for the microphone, speaker and buzzer. Used waterproof hermetic coating, sealed connectors, a thick display mounted on a special substrate. The antenna is made of elastic material. The body is combined from a set of plastic and rubber parts. The power battery is fixed on special rubber guides (see “Phone Νο1 <; · ι 6250. Description and user guide”).

This phone company Νο1 <ί; · ι. like all known solutions, it is not possible to significantly increase the reliability and durability of work. These drawbacks are a consequence of the traditional layout used. As a rule, electronic circuits including transceiver circuits and user interface circuits are assembled in the case of a portable telephone. User interface diagrams include a display, a keyboard, a speaker (auditory shell), and a microphone. The body usually consists of a back standard casting form mated to the front part of the body, which has another standard casting form, or of two such halves connected by means of a turning mechanism (the so-called shell shell or clamshell (Eng. - ίΐίρ-ryoie Usually, user interface elements (display, speaker, keyboard) are mounted in the front (front) part of the housing and electrically connected to the electronics and transceiver circuits installed inside the housing.

From a functional point of view, any cell phone can be divided into five basic modules:

Terminal Electronics Module, Display Module, Keyboard Module, Battery Module, Case Module.

In the existing models of cell phones, including the Iok1a 6250 phone, the functional modules are not separated into separate units, but rather integrated into a single construct with a common (single) case. In the known construction, impact pads are used only for individual functional units, and their thickness cannot be significant.

Summary of Invention

The task to be solved by the proposed device is to create a new layout scheme, which allows to increase the reliability and durability of wearable electronic devices.

Achievable technical result is to increase the service life of a wearable electronic device and ensure data integrity under shock effects and with negative environmental effects (dust, sea and fresh water, etc.).

The task is achieved by the fact that in the proposed layout the functional modules of any wearable electronic device, including cell phones, are divided into groups. One group includes display, electronics, and battery modules, while the other includes keyboard and / or dialer modules. The first group of modules is placed in a sealed durable case, which is internal to the external case, on which is placed the keyboard and / or dialer. The inner case is installed inside the external one with a gap in which shock absorbing means are placed. The interaction between the functional modules of the inner and outer housings is carried out by means of electrical, acoustic, radio or optical interfaces. Structural elements of the outer case are made easily removable. In the gap between the outer and inner housings are placed shock-absorbing elements or layers.

By the example of a mobile phone, these groups can be represented as follows: the first group includes a display, all electronics (including a transceiver) and a battery; the second group is the keyboard and / or dialer.

As a rule, in modern phones, the keyboard consists of a dialer and additional service keys (buttons) of control.

The first group of functional modules is placed in a sealed durable case, which is internal to the other case, the external one. Separating the electronics of the terminal, the display and the battery into a separate, durable, sealed case allows you to negate the number of moving parts and points of water and dust penetration through the keyboard buttons, technological holes and slots, connector “windows”, etc.

On the external case is placed the user interface (keyboard, dialer, etc.). The outer case acts as a sheath (case, cuirass) to protect the functional modules located in the inner case. To ensure the impact resistance of the keyboard, implemented and placed on the outer case, you can use strain gauges that are not afraid of shocks, dirt, dust and water. Structural elements of the outer shell can be easily removable (replaceable) and have a low cost.

The inner case is installed inside the outer case with a gap (depreciation zone), in which shock-absorbing fastening elements, shock-absorbing layers, etc. can be located.

Communication between the functional modules of the internal and external enclosures can be carried out using electrical, acoustic, radio or optical (contact or contactless) interfaces. The battery module can function as a chassis of a robust housing to combine the module containing all the electronics of the terminal and the display module into a single unit. The electronics and display, if placed inside the battery case, will be additionally protected by the battery case.

The electronics module of the terminal can be placed in a separate case in which all the main electronic components of the mobile wearable terminal are located: a processor, memory chips, controllers, a radio unit consisting of a radio receiver and a radio transmitter.

Between the inner "hard" and outer "light" buildings is a zone of depreciation. It is several millimeters and can be made in the form of a shock-absorbing layer. The cushioning layer may be simple or complex, may contain collapsible or compressible elements and / or gas cavities. The thickness of the cushion layer may be uneven. Under impact, the damping layer held by the outer shell will absorb the impact energy due to the deformation. It should be noted that with this design of the damping layer, it will protect all the electronics of the terminal, the battery and the display, placed in the inner case, and not the individual functional units and elements. Excessive impact may cause destruction of the outer casing, crushing of the shock-absorbing layer, but the operability of the electronics, and hence the operability of the terminal (including data integrity), remains.

The proposed layout is illustrated with a specific example of the layout of a mobile phone, which is not the only one, but it clearly demonstrates the possibility of achieving the indicated set of essential features of the expected technical result.

List of figures drawings.

FIG. 1 shows the division of the functional modules of a mobile cellular phone into two groups with the subsequent placement of these groups in two buildings: internal and external.

FIG. 2 shows the front and side sections of the proposed layout scheme.

FIG. 3 shows embodiments of a damping layer.

FIG. 4 shows the use of the proposed layout for creating wearable electronic devices.

Information confirming the possibility of carrying out the invention.

The proposed layout of the mobile phone 1 (see Fig. 1) can be divided into five functional modules (or blocks):

2.1 - terminal electronics (including radio unit);

2.2 - a display designed to display (view) information;

2.3 - body (complex or composite), combining all the elements into a single whole;

2.4 - a rechargeable battery that provides electrical power to the electronics of a mobile phone;

2.5 - a keyboard consisting of a dialer and additional keys (buttons) of mobile phone control.

The essence of the proposed technical solution consists in combining blocks 2.1, 2.2, 2.3 and 2.4 into module 3.1 - “Inner housing” and in combining blocks 2.3 and 2.5 into module 3.2 - “External housing” with further placement of module 3.1 inside module 3.2 with clearance.

- 3 007175

The space between modules 3.1 and 3.2 can be used to organize a shock-absorbing layer (for damping external shocks and weakening their influence on the operation of the terminal electronics); the relative position of the modules is displayed in block 4.1. Such a transformation will not lead to a significant change in the traditional appearance of the mobile phone (see 5 in Fig. 1).

FIG. Figure 2 shows the frontal 4.1 and side 4.2 sections of the proposed layout scheme.

The proposed layout allows the use of various versions of the damping layer (see Fig. 3):

cushion layer may be uniform, see cut phone 2;

the shock-absorbing layer can be organized by a group of elastic and / or collapsible independent (separate) elements placed between the outer and inner shells, see cut phone 3;

elastic elements forming a cushioning layer can be integrated with the outer case, see the cut of the phone 4;

the outer shell and the damping layer can be formed by the unique properties of the material used to manufacture the outer shell, see the cut of the phone 5;

The damping layer can be arranged by a gas tank placed between the outer and inner shells, see the cut of the phone 6.

The terminal electronics module 2.1 can be placed in a separate case in which all the main electronic components of the mobile wearable terminal will be placed: a processor, memory chips, controllers, a radio unit consisting of a radio receiver and a radio transmitter.

Such a module in a separate package may have a standard (unified) standard design. This allows mobile phone manufacturers to create and maintain a wide model range based on a single typical module, changing only the overall dimensions of the used batteries, displays, external enclosures (with a keyboard). When mass production of standard modules "Electronics Terminal" can be significantly reduced their cost. The terminal electronics module, which has its own housing in FIG. 4, conventionally called the cellular processor.

FIG. 4 presents as an example three possible options for building cell phones based on a typical module (cellular processor).

Option "A" allows you to create a cell phone in the form of a pen with an inline display on the base of the cellular processor. To do this, use a small battery, a narrow display and a compact body with a minimized keyboard.

Option "B" allows you to create on the basis of the same cellular processor more traditional cellular phone with a conventional display, keyboard and case, visually no different from existing models of cellular phones.

Option "C" allows you to create on the basis of a standard cellular processor personal cellular mini-PBX, which may contain Ν-cellular processors that can support different standards of cellular communication (AMT8, S8M, SAMA, υΜΤδ / ΤΌΌ, SEML-2000, etc.) . Each of the cellular processors can be registered with different mobile operators. This will allow the user to minimize the cost of cellular communication, using the most favorable on-net tariffs. This will also reduce roaming (guest) service.

The proposed layout, illustrated by the example of a mobile cellular phone, can be widely used in the design and manufacture of all mobile wearable electronic devices (mobile phones, wearable radios, electronic notebooks, pocket personal computers (PDA, yapbu, 5step1-p1yups. Handheld computers), digital cameras, etc.).
