Description

The present device relates to elements of computer computing, in particular to removable devices for recording and reproducing information, also called "USB flash drives". Such removable storage devices are used as a storage medium so-called. "Flash memory", equipped with the necessary elements for its functioning, including a microcontroller, a quartz resonator, etc., and such devices are connected to a computer or other reading device via the USB interface. The main purpose of USB-drives - storage, transfer and exchange of data, backup, loading operating systems, etc. [1].

Typically, the device has a flat, elongated shape and a removable cap that covers the plug; sometimes a cord is included for wearing on a keychain. Modern flash drives can have a wide variety of sizes and connector protection methods, as well as a “non-standard” appearance and various additional features (for example, a write protection device, a password input device, a fingerprint reader, etc.). In addition, they can be equipped with multiple USB ports for various devices, including laptops, tablets or smartphones, for example, with USB type A and microUSB type B, and the connectors themselves can be either fixed or retractable.

Known device USB-flash drive for recording and reproducing information from it, described in detail in [2]. Such a device includes a protective case, consisting of one or more parts, and main and additional components inserted into the case, ensuring the operation of the flash drive as a whole. The main components include NAND memory chips (flash memory), a microcontroller, a crystal, and a USB connector or connectors that can be protected by caps. Additional components can include an indicator LED, devices for extending USB connectors, devices for protecting a drive from writing, including in the form of a mechanical switch or a keyboard for entering a passcode. We have chosen this technical solution as a prototype.

Often there is a need to use a large number of flash drives, for example, with frequent professional video filming,

copying accounting information in large companies, during daily astronomical observations, etc. It is clear that if there are a large number of flash drives in constant operation, it becomes necessary to visually mark them somehow, which allows you to quickly select the desired flash drive without connecting it to a computer or another reader. Marking records can be any information about the information recorded on this flash drive, for example, the date and place of recording, serial number, names of key files, operating systems and other useful data.

The main disadvantage of the known flash drive is the difficulty of marking it, for example, with a special marker, gluing tags, etc. Such methods are unreliable and not aesthetically pleasing - the marker can be erased, the tag can come off, etc. Therefore, for the purpose of storing and marking flash drives, special separate plastic cases with a fastening pocket are often used, where you can put the flash drive itself and an explanatory note with information, as indicated in [3].

The task is to create a removable USB flash drive for recording and playback with the possibility of marking it without the use of separate additional cases with pockets.

The problem is solved by the declared USB flash drive for recording and reproducing information from it, including the case and installed main and additional components in it, characterized in that on the outer surface of the flash drive case there is a storage for placing the visual marking of the flash drive on a flat medium. which is a flat base in plan, bounded by a structure adjoining the upper surface of the base of three runners identical in cross-section - each with the same internal rectangular grooves in cross-section, and two runners with a length equal to M are located parallel to each other at a distance equal to K, and the third is located perpendicular to the first two, and all three form together the "letter" P ", all slots of the runners are located inside the" letter P ", forming a single slot, the height H of the lower part of the runners to the beginning of the slot is at least 0.2 mm, in single groove of the structure inserted all the way rectangular in plan removable flat to storage lid, having at one end a transverse - across the entire width of the lid - a step oriented towards the body of the flash drive and protruding above the plane of the storage lid by an amount H equal in magnitude to the height of the lower part of the skids H, the thickness of the storage lid T coincides in size with the thickness slots T of the skids, the width of the storage lid W is equal to the sum of the distance between two parallel skids K together with twice the depth of the grooves

D in accordance with the formula W = K + 2D, and the length of the storage lid L along its central axis from the inner vertical surface of the step to the other end of the lid is equal to the sum of the length of one of the parallel skids M together with the depth of the groove of the skids D in accordance with the formula L = M + D.

Preferably, the flat storage base can be made by aligning the top of the flash drive body, and the storage bounding rails can be manufactured integrally with the flash drive body, or made separately and then mounted to the surface of the flash drive body.

In addition, the flat vault base and bounding rails can be fabricated separately and then installed on the flash drive body, or both the flat storage base and bounding rails can be fabricated separately and then assembled into a single piece with the flash drive body.

Also preferably, the removable cover covering the additional information store can be made of a transparent material, which allows you to visually read the marking of the flash drive and other relevant information without opening the removable cover.

As a flat recording medium for marking, any suitable material suitable for storage and on which marking recordings with paint, ink, etc. can be made - paper, cardboard, plastic, woven and non-woven materials, etc.

If necessary, the described storage for marking a flash drive can be arranged on any available surface of the flash drive case in the case of various design solutions for its design. In this case, the central axis of the "letter" P "of the storage runners can be oriented along, across or inclined to the central axis of the flash drive.

The claimed device works as follows: on a flat carrier, suitable in size for the dimensions of the storage, write down the necessary information on the marking of the flash carrier, then place this note in the storage on the surface of the case, orient the removable flat storage cover with a step towards the body, then slide it into the grooves removable cover and push it all the way. Due to the frictional forces due to the fact that the thickness of the lid and the grooves of the rails are the same, the lid is inserted into the rails with enough force to hold the lid in place, and a step on the lid closes the gap between the lid and the base of the vault, which prevents accidental

falling out of a note with markings. The depth of the store, in accordance with the description, is not less than 0.2 mm and is numerically equal to the height of the step H on the lid and the height of the lower runner to the beginning of the groove, into which the removable cover enters when closing the store.

If necessary, several flat storage media can be placed in the storage, if the thickness of the labeling media and the size of the gap between the cover and the base allow.

In the event that the cover is made of a transparent material, the note on the storage medium in the storage is easily visually readable through the cover.

Figure 1 shows a perspective view of one embodiment of a flash drive having a somewhat convex and elongated body. For ease of perception, the storage structure is shown with a 50% cut along its longitudinal axis.

The storage structure depicted in Figure 1 has an independent base 1 adjoining its lower surface to the upper surface 2 of the flash drive body. The bottom surface of the base matches the top surface of the main body of the flash drive. The upper flat surface of the base 3 has two parallel skids 4 installed on it with a length equal to M each, located on the base at a distance of K from each other (the second skid is not shown, since it fell into the cutout) and one skid 5, installed perpendicular to the first two and the same cross-section as the first two. All three runners together form a "P" on the surface of the flash drive body, and the grooves of the three runners together form a single common groove 6, into which a removable cover is then inserted. Figure 2 is a front and top view of the described storage structure. Figure 3 shows a perspective view of a removable cover to the structure of the storage 7 with a step 8, and for ease of perception in Figure 3 the step of the removable cover is directed upwards, while when assembling the entire structure, the step is oriented downward towards the body of the flash drive.

The dimensions of the grooves of all three runners coincide with each other and are the value D in depth and the value T in thickness, and the value of T is also equal to the thickness of the removable cover (without a step). The step protrudes above the plane of the storage lid by an amount H equal to the height of the lower part of the skids N. The width of the removable storage lid W is equal to the sum of the distance K between two parallel skids together with the doubled depth of the grooves D in accordance with the formula W = K + 2D, and the length vault lid L from the inner vertical surface

the steps to the other end of the cover are equal in magnitude to the length M of one of the parallel skids plus the depth of the groove of the skids D in accordance with the formula L = M + D. The indicated dimensions allow the storage to be closed tightly with a removable lid, and the step of the cover 6 does not allow a note with the marking of the flash drive to accidentally fall out of the storage, since the height of the step H overlaps the storage gap under the lid, equal to the height H from the base of the runners to the beginning of their grooves.

In the examples 1-5 below, various embodiments of the claimed invention are presented. The specific dimensions of the parts given in them in no way limit the possibilities of the proposed utility model both in terms of the storage capacity for marking and in its geometric dimensions.

Example 1.

The removable 16 GB USB flash drive is housed in a plastic case with one fixed USB connector. The body of the flash drive is 12 mm wide and 55 mm long without a connector. On the upper part of the body, on one side, there is a construction of the storage of information on the marking of the carrier, for which, on one side, the body is made with a flat platform serving as the base for the storage.On this base, there are two identical longitudinal skids along the longitudinal axis of the body, each with a length of M = 18 mm ... The distance K between the skids is 4.5 mm. Perpendicular to the parallel skids is the third skid, forming with the first two "letter" P ". The cross section of all three runners is the same and is 2.5 x 2.5 mm. All skids have a groove located in the center of the section of each skid with dimensions of 1x1 mm. The grooves are located on the inner side of the "letter" P "and form a single groove. Distance H from the beginning of the base to the beginning of the groove of the runner is 0.75 mm.

Part of the body of the flash drive, the flat platform and the rails installed on it, which form the storage, are made as a single whole on a 3D printer.

The removable storage lid is a stamped flat rectangular plate of transparent plastic with a thickness T equal to 1 mm and a width W equal to 4.5 + 1 + 1 = 6.5 mm. There is a step on the plate, made in the form of a single whole with the plate itself. The step is a parallelepiped with a square section of 0.75 × 0.75 and a length of 6.5 mm. The step is located at one end of the plate perpendicular to its longitudinal axis. The length of the plate L from the inner vertical surface of the step to the other end of the plate is 18 + 1 = 19 mm. Thus, when the removable cover is slid into the grooves of the storage until it stops when the step is oriented downward towards the body of the flash drive, a closed space is formed on all sides.

This space has internal dimensions of 18 mm by 4.5 mm and 0.75 mm and is used to store additional information on flat media. The dimensions of the internal space are quite sufficient for placing a piece of paper, plastic, cloth, etc. with the necessary information recorded. The information itself can be read through the transparent storage lid.

Example 2.

The body of a flash drive is made according to example 1, but all the skids are manufactured separately and then they are glued to a flat base, which is part of the body according to example 1. As a result, it becomes possible to increase the production capacity by making stamped skids.

Example 3.

As a body of a flash drive, a conventional body is used, which, as a rule, has a slightly convex oblong shape. A flash drive has a USB connector at each of its two ends - one for the usual format, the other for the micro-format for connecting to a tablet, smartphone, etc. Separately, as a whole, a storage base with storage rails installed on it is made on a 3D printer, and the lower side of the base has a profile corresponding to the upper surface of the flash drive body. The storage lid is made by stamping. The dimensions of vault c and its removable lid are the same as those of Example 1. When the vault and flash drive are assembled by gluing into a single whole, a structure is obtained that is almost completely identical to example 1. The difference is that the removable vault lid is opaque.

This example demonstrates the possibility of converting standard flash drives into a modernized one according to this technical solution.

Example 4.

As a body of a flash drive, a conventional body is used, which, as a rule, has a slightly convex oblong shape. The flash drive has one regular retractable USB connector. Separately, the base of the storage, the skids of the storage structure and the removable cover to it are made by stamping. The underside of the base has a profile that matches the top surface of the flash drive case. The dimensions of all the parts and the removable cover of the storage are the same as those of example 1. When the storage and flash drive are assembled by gluing into a single whole, a structure is obtained that is almost completely identical to example 1.

This example demonstrates the possibility of reworking standard flash

drives into upgraded according to this technical solution, and thanks to the stamping technology, the performance of upgraded flash drives is very high.

Example 5.

The utility model is made according to example 1, except that the cross-section of the runners is not square, but rectangular with a width of 2.5 mm and a height of 5.0 mm. Thus, the distance H from the bottom of the rail to the beginning of the groove is 2.0 mm. Accordingly, the height of the step on the removable cover H is also increased to 2.0 mm. Thus, when you close the lid in the vault, a larger, enclosed space with a thickness of 2.0 mm is created on the surface of the flash drive, where several notes with markings and other information can fit.

As follows from the presented examples 1-5 of a specific implementation, compliance with the stated conditions allows the production of modernized flash drives on an industrial scale, as well as converting standard flash drives into modernized ones. They all have additional storage for additional labeling information.
