200528005 九、發明說明： 【發明所屬之技術領域】 發明之領域 本發明係有關於具有一可密封開口的抗衝擊殼體，尤 5 其是有關於防塵且防水的封口。 【先前技術】 發明之背景 電子殼體基本上係設計成可保護内裝物品。此外，其 ® 亦備置美觀、合乎人體工學、重量、裝飾及其他功能，因 10 為殼體通常是人們與物品的界面基礎。此界面可僅為感覺 (視覺）上的，或為物品使用的基礎，譬如，使用者在包裝上 支撐物品，以使用它。譬如，一可攜式鑽孔機的殼體亦可 為工具殼體，且操作者手持殼體，以使用工具。因此，殼 體為一種多功能的物品，且設計須符合所有必要的功能上 15 之需求。 近年來可攜式電子裝置造成電子物品，如平板電腦、 ^ 手機、攝影機、相機、掌上型電腦等需要堅固的額外殼體。 這些第二殼體使物品設計成使辦公室用品可用於不良氣候 ^ 的戶外。需要保護外殼產生的數種傷害；而兩種主要的傷 - 20 害為撞擊(掉落)及環境(水以及/或灰塵）。當保護功能與美觀 或人體工學合併時，即會產生挑戰。 在傳統上，運輸殼體設計成可吸收能量。若能量吸收 為唯一的需求，則存在許多低價的選擇，因為大體上若殼 體較大，其較容易設計成吸收能量。譬如，泡沫塊置於易 200528005 碎内容物及盒（殼體）之間的一波浪狀盒中，而盒（殼體）及這 些泡沫塊可提供高程度的撞擊保護。然而，如此會使包裝 變大及笨重。若除了抗撞擊外，殼體須提供''使用者界面〃， 此方式會使殼體較實用的殼體大很多，且就感覺而言，它 5 會大的難看。作為一使用者界面殼體，此為不實際的。因 此，使用者較喜歡的附加殼體須設計成縮小其尺寸，重量 並儘可能符合人體工學。 大部份手提式電子裝置需要在裝載於一附加殼體（譬 如一保護外殼）中但可容易搆及之特徵。譬如，個人資料助 10 理器（PDAs)具有可移開的記憶卡、電池、同步電線以及/或 電線。然而，在基本的操作狀況下，最好能夠在不自其保 護外殼中移除物品的狀況下使用或搆及這些配件。除能量 吸收需求外，加入一功能性的需求，如存取功能，在習知 技藝中會增加零件的數量，設計之複雜性以及製造保護外 15 殼的價格。當尺寸、重量、保護、美觀性、符合人體工學、 使用者存取以及或更多的需求存在時，保護外殼可能會需 要較物品本身更多的設計。習知解決此問題的方式為使保 護外殼的設計配合可攜式電子裝置，然而，此種解決方式 耗時且昂貴。 20 另一種價廉的方式是為可攜式電子裝置備置一具有多 功能的保護外殼，如可吸收撞擊力，且具有内部存取性。 【發明内容】 發明之摘要 本發明為價廉的撞擊力吸收嵌入物，其整合各零件而 200528005 提供多功能性，且容易符合各別顧客的需求，因而可有廣

Description of the invention: [Technical field to which the invention belongs] Field of the invention The present invention relates to an impact-resistant casing having a sealable opening, and in particular, it relates to a dust-proof and waterproof seal. [Prior Art] Background of the Invention The electronic case is basically designed to protect the contents. In addition, its ® is also equipped with aesthetics, ergonomics, weight, decoration and other functions, as the shell is usually the basis of the interface between people and objects. This interface can be only sensory (visual) or the basis for the use of the item, for example, the user supports the item on the packaging to use it. For example, the casing of a portable drilling machine can also be a tool casing, and the operator holds the casing to use the tool. Therefore, the shell is a multifunctional item and the design must meet all necessary functional requirements15. In recent years, portable electronic devices have caused electronic items such as tablet computers, mobile phones, camcorders, cameras, palmtop computers, and the like to require sturdy extra cases. These second shells make the items designed so that office supplies can be used outdoors in adverse weather ^. There are several types of injuries that need to be protected by the enclosure; the two main types of injuries-20 are impact (drop) and environment (water and / or dust). Challenges arise when protective functions are combined with aesthetics or ergonomics. Traditionally, the transport housing is designed to absorb energy. If energy absorption is the only requirement, there are many low-cost options because, generally speaking, if the shell is larger, it is easier to design to absorb energy. For example, foam blocks are placed in a wavy box between the broken contents and the box (shell), and the box (shell) and these foam blocks can provide a high degree of impact protection. However, this can make the packaging large and bulky. If in addition to impact resistance, the shell must provide a `` user interface '', this method will make the shell much larger than the practical shell, and in terms of feeling, it will be ugly. As a user interface housing, this is not practical. Therefore, the user's preferred additional housing must be designed to reduce its size, weight, and ergonomics as much as possible. Most portable electronic devices require features that can be easily housed in an additional housing, such as a protective housing. For example, personal data assistants (PDAs) have removable memory cards, batteries, sync cords, and / or cords. However, in basic operating conditions, it is best to be able to use or construct these accessories without removing items from their protective enclosure. In addition to energy absorption requirements, adding functional requirements, such as access functions, will increase the number of parts, the complexity of the design, and the price of manufacturing protective housings in the conventional arts. When size, weight, protection, aesthetics, ergonomics, user access, and / or more are present, the protective enclosure may require more designs than the item itself. The conventional way to solve this problem is to match the design of the protective case with the portable electronic device. However, this solution is time-consuming and expensive. 20 Another inexpensive way is to provide a portable electronic device with a multi-functional protective casing, such as absorbing impact forces and having internal accessibility. [Summary of the Invention] Abstract of the Invention The present invention is a low-cost impact-absorbing insert, which integrates various parts, and 200528005 provides versatility, and easily meets the needs of individual customers, so it can be widely used. The impact-absorbing insert of the present invention cooperates with a user-defined housing to form a protective casing for any fragile objects used in a portable environment, such as a portable electronic device, such as cameras (35 mm and Digital), 5 instruments, tools, PDAs, tablets, laptops, mobile phones, pagers, game consoles, electronic music players, recorders, satellite positioning systems (GPS), etc. Another object of the present invention is to reduce the number of parts and improve the convenience of use of the impact-absorbing insert. 10 Another object of the present invention is to provide versatility by designing an impact-absorbing insert in a housing that is suitable for one or more different user-defined enclosures. This reduces the complex design required for each item, while allowing only complex-designed energy absorbing devices to be placed in the insert. In one embodiment, the present invention is an impact absorbing insert, which is provided as a protective shell for loading and protecting fragile articles, wherein the insert includes one or more impact absorbing parts and one or Several are seized to insert into an access channel installed in a cooperating user-defined housing, in which various devices of the article can be constructed by the access channel. In another embodiment, the present invention is a protective shell for a fragile article. 20 The impact shell includes the impact absorbing insert of the present invention, and a user-defined shell, wherein the protective shell is provided with impact protection, and when the access channel is accessed When plugged, a waterproof and dustproof seal is provided for fragile items. In another embodiment, the impact-absorbing insert comprises a molded polymeric material, preferably a low-hardness, highly elastic polymeric material, such as an elastic thermoplastic or 200528005 elastic thermosetting plastic, preferably a thermoplastic polyamine. Another embodiment of the present invention is to hold the impact-absorbing insert in a user-defined housing by designing a connection device that forms a tight joint between the impact-absorbing insert and the user-defined housing, such as in The molded fingers on the user housing and the grooves on the impact-absorbing inserts, and the fingers and grooves on the impact-absorbing inserts are on the impact-absorbing inserts or a combination thereof. In another embodiment of the present invention, the impact force absorbs the impact force of the insert and the collapsing includes one or several integrally formed energy absorbing plates and ribs 10, which are compressed or deformed to absorb the impact force, and are molded. Buttons, ribs, decorative devices, joint ribs, interference tolerances, so that the article has a positive fit and function, or both. Another embodiment of the present invention allows the insert to be easily manufactured by using general injection molding techniques and tools for switching operations. 15 Another embodiment of the present invention is a protective casing for a portable electronic device, which includes the impact-absorbing insert of the present invention inserted into a user-defined casing, an improved user-defined casing, and The electronic article loaded therein is sufficient to pass the drop test described in the MIL-STD-810F, 516.5-Vi table at a minimum of 24 inches. 20 Brief Description of Drawings Figure 1 is a cross-sectional perspective view of the interior of a protective casing of a portable electronic device including an impact-absorbing insert and a matching user-defined housing; FIG. 2 is a cross-sectional perspective view of an external view of a protective casing of a portable electronic device including a shock-absorbing insert and a matching 200528005 user-defined housing; FIG. 3 is provided with A cross-sectional perspective view of an elongated piece of an impact-absorbing insert and a mating user-defining protective shell; 5 and 4 are diagrams including an impact-absorbing insert and a mating protective shell Perspective view. [Embodiment] Detailed description of the invention 10 The impact force absorption object 1 shown in the first figure has an outer surface 2 and an inner surface 3. In addition, the impact-absorbing insert has one or more impact-absorbing portions 4 and one or more tethers 5. At least a portion of the outer surface of the insert, such as an impact force absorbing portion, is designed to be secured within an outer surface 21 of the user-defined housing 20. The user-defined housing includes a top portion 15 and a bottom portion 23, and each has an inner surface 24. The user-defined housing including the impact-absorbing insert includes a protective housing 30 (FIG. 4) of a portable electronic device 40. Preferably, the outer surface of the impact-absorbing insert must be tightly against the inner surface of the housing defined by the user. Any device that can tightly define the shell 20 against the user is acceptable. For example, it can be fixed with an adhesive, a holder, a mechanical device, or a combination thereof. An example of the mechanical device is shown in FIG. The insert is supported by the fingers 25, which are molded onto the inner surface of the user-defined housing that engages the recess 6 on the outer surface of the insert. Alternatively, the grooves may be on the inner surface of the user-defined housing, and the fingers or each surface embedded in the outer surface of the 200528005 object may have one or several grooves,-one or several fingers Shape, or a combination thereof. When a portable electronic device is placed in a protective case, it must be firmly fixed against the inner surface of the object after the impact force is absorbed. The external surface of the insert preferably has integrally formed ribs and protrusions 7 which (1) provide clearance to prevent the portable electronic device from contacting the inner surface of the user-defined housing and / or dropping It touches the ground during an impact, and (2) absorbs the energy generated by falling. In addition, the impact absorbing desire may include one or more molded buttons, ribs, access channels, aesthetic devices, tethers, 10 ribs, or interference tolerances, so that the article has a positive fit And functions. These devices are designed to perform specific functions based on the needs of portable electronic clothes and terminal items. Preferably, the impact-absorbing insert must have a sufficient structure to prevent it from collapsing during an impact and still be able to absorb at the same time the amount of energy generated by the fall, so as not to damage the portable device and protect it . It is best to insert it • 4 Do not have enough f-curved fatigue resistance ’to return to its original position after being pressed when a drop or other impact occurs. It must be sturdy enough to maintain its M in the user-defined enclosure during normal operation to minimize undesired movement of the electronic device in the user-defined enclosure. 2． Correction. The impact force absorption character must have good anti-dissolution and tilt characteristics under pressure for a long time, so that it will not sag or zigzag with time. In addition, it is desirable that the impact-absorbing insert be sufficiently resistant to thorium, so that it is best to be called at 40 in a variety of climatic conditions. & to delete). Encapsulated portable 200528005 devices can also cause thermal problems, and impact-absorbing inserts must counteract these problems without deformation or loss of function. As shown in Fig. 2, the tether plug 5 is integrally formed with the impact absorbing portion of the impact force absorbing insert. It includes a bolt portion 9 and a tether portion 10. The bolt portion has an outer surface U and an inner surface 12. The tether bolt is designed to pass first and then be neatly secured to an opening or access channel 26 in the user-defined housing, which access channel allows the user to define the housing / protective shell outer structure and be positioned for use The portable electronic device in the defined case / protective case does not need to be opened. The user-defined case / protected case does not need to be opened (for example, a memory 10 card can be removed, a battery can be replaced, a synchronous wire can be connected / detached, and inserted. / Remove a headset, insert / remove a wire, etc.). The bolt is designed to be inserted and removed from the outer surface of the user-defined housing, and at the same time maintains connection to an insert on the inner surface of the user-defined housing by a tether through the user-defined housing opening. Shock absorber. When the plug is inserted into the access channel, it preferably forms a waterproof and / or dust-proof seal from the outside of the user 15 delimiting housing. The impact-absorbing insert may have a plurality of tethering bolts for sealing a plurality of mating access channels in a user-defined housing according to the special needs of the portable electronic device housed in the protective housing. Preferably, the impact force absorbs the object to be formed into a thin wall equal to or greater than about 2 microns and 20 (mm) in thickness, and the thickness of the integrally formed device (impact absorber, tether, bolt, etc.) is preferably equal to or greater About 1 mm, preferably equal to or greater than L5 mm, and most preferably equal to or greater than about 2 mm. The thickness of the thickest thin-walled and integrated device is limited only by the practicality of specific housings and portable electronic devices, but in general, it is equal to or less than about 25, and is preferably equal to or less than about 12 mm, and preferably about 6 mm or less. Impact-absorbing inserts can be made of polymeric materials, which can (1) be made with the necessary geometric design, and (2) be placed on the user's definition 5 in the shell, it defines the shell can maintain its shape for a long time under different environments. Preferably, the polymeric material is a thermoplastic or thermosetting elastomer. Suitable elastomers are disclosed, for example, in the fourth book published by Interscience Press, New York, by Billmeyer F., in Polymer Science (1965) —the book, and by K irk-0thmer, published by John Wiley & Sons, New York. Edition of Science and Technology in Science and Technology (19 93). ίο Impact-absorbing inserts can be made of any low-coefficient and highly elastic elastomeric thermoplastic or thermoset material.
