Abstract
The invention provides a capacity-expandable memory which comprises a carrier and a memory unit, wherein a plurality of slots are formed in the carrier; and by inserting a plurality of memory cards into the slots, the memory capacity of the whole memory is increased. By arranging the plurality of slots which are respectively adapted to the plurality of memory cards, the memory cards can be inserted into and pulled out from the slots according to demands; when data need to be copied and the capacity of the memory is not adequate, only the memory cards need to be inserted into the slots; electric contacts of the memory cards are contacted with electric contacts of the slots; and a control unit reads the data information of the memory cards and carries out reading and writing operation on the memory cards; the plurality of memory cards are all inserted into the slots of the memory, then the capacities of the plurality of memory cards are overlapped, so that a larger memory space is obtained, and the limit of the memory capacity of a single memory is broken.
Description
Technical field
The present invention relates to storer, but refer to especially have a kind of storer of increase-volume.
Background technology
The style of existing various storeies is more and more, common portable storer has USB flash disk, portable hard drive, various storage cards etc., the use of mobile memory, for people work and life have brought a lot of facilities, people need to regularly use portable storer to carry out data and preserve, in the time can't continuing to store because memory capacity is limited, need the original partial data of deletion could continue to use, for the user has brought a lot of inconvenience.Simultaneously, because the as a whole formula storer of mobile memory, only carry out partitioned storage at the internal electron storage space, do not cut apart storage in physical space, the electricity operation must be connect and data transfer and storage could be realized, can not directly partial data be deposited other internal memories in addition, have certain limitation in memory capacity and storage mode.
Summary of the invention
Based on the deficiencies in the prior art, fundamental purpose of the present invention is to provide a kind of and a plurality of memory card slots is set with the storer of a plurality of storage cards of pegging graft, and has enlarged the memory capacity of storer.
In order to realize the foregoing invention purpose, but the invention provides a kind of storer of increase-volume, comprise carrier and storage unit, described carrier is provided with several slots, by inserting several storage cards at described slot, to increase the memory capacity of whole storer.
Preferably, described carrier further comprises lid, and it is covered on the slot opening or closing, and described lid has out page or leaf, and the one end is fixed on the carrier, and the other end can be fastened on the carrier, with described several storage card package in carrier.
Preferably, described slot comprises the draw-in groove that several are separated from each other, and the degree of depth of described draw-in groove and width and storage card are suitable, is provided with the contact that is electrically connected with storage card in the described draw-in groove.Take in corresponding storage card by draw-in groove, by realizing data transmission between the control module of electrical contact with storage card, draw-in groove and storer, to realize the independent read-write operation of each storage card, make things convenient for lock out operation.
In the present invention, described storage card can be chooses any one kind of them in SD card, CF card or the TF card or multiple, and described storer is USB flash disk or portable hard drive.The capacity of described storer is capacity and the stack of former internal memory of each storage card.
Preferably, in the described slot scalability ground insertion vector, described draw-in groove is provided with the electrical contact that is electrically connected with carrier.By the structure of retractility, realize the plug of storage card.
Compared with prior art, but the storer of a kind of increase-volume of the present invention is by arranging a plurality of slots, suitable with several storage cards respectively, storage card can plug operation at slot as required, when the needs copies data, find the off-capacity of storer, only need storage card is inserted in the slot, the electrical contact of storage card contacts with the electrical contact of draw-in groove, control module may be read into the data message of storage card, and it is carried out read-write operation, several storage cards are all inserted in the slot of storer, the capacity of several storage cards can be superimposed, obtain larger storage space, broken through the restriction of the storage space of single storer, for the user has brought a lot of facilities.Simultaneously, can carry out independent read-write operation to each storage card respectively, realize the separate type mobile storage, to store the data storage card extracts from storer, access in addition again other electronic equipments and carry out read operation, broken through the limitation of the storage mode of storer, carried out cutting apart of physics in the data storage, be stored in independently on the required storage card, shift or transmission with convenient.In addition, the outer setting lid by at storer encapsulates storage card; storage card comes off or the dirt ash fouling when avoiding using, and certain protective effect is played in the use with the storer of storage card, and do not increased the volume of storer; be convenient for carrying handling safety.
Description of drawings
But Fig. 1 is the structural representation one of the storer of a kind of increase-volume of the present invention;
But Fig. 2 is the structural representation two of the storer of a kind of increase-volume of the present invention;
But Fig. 3 is the flat state figure of the storer of a kind of increase-volume of the present invention.
Embodiment
With reference to Fig. 1-shown in Figure 3, but the invention provides a kind of storer of increase-volume, comprise carrier 1 and storage unit 2, described carrier 1 is provided with several slots 10, by inserting several storage cards 3 at described slot 10, to increase the memory capacity of whole storer.By setting up several storage cards 3 at carrier 1, the memory size stack that capacity and the storer of storage card 3 carried is to increase the memory size of storer.
Described storer is USB flash disk or portable hard drive, in the present embodiment, is described as an example of USB flash disk example.The carrier 1 of described storer is cylindricality, and its front end extends USB plug, is used for the USB slot to suitable, with the data of storing in the read memory.
In the present embodiment, described slot 10 is located at the same side of storer, described slot 10 comprises several draw-in grooves that is separated from each other 102, described draw-in groove 102 on same straight line, the space, the degree of depth of draw-in groove 102 and width and storage card 3 are suitable, the width of described each draw-in groove 102 and the degree of depth can be inconsistent, and multiple draw-in groove 102 is set, with adaptive dissimilar storage card, for the space of extended memory provides more washabilitys, described storage card can be SD card, CF card or TF card.Be provided with the electrical contact that is electrically connected with storage card 3 in the described draw-in groove 102, by described electrical contact so that the storage card 3 that inserts in the draw-in groove 102 can be electrically connected with the control module of storer, read and write data in each storage card 3 by control module, broken through the limitation of the storage mode of storer, carried out cutting apart of physics in the data storage, be stored in independently on the required storage card 3, shift or transmission with convenient.Be appreciated that described draw-in groove 102 can be arranged at the optional position of carrier 1, preferably, be located at the same side of storer, the contact of draw-in groove 102 is welded in homonymy, has simplified inner structure and manufacturing process, so that storer is more compact, do not increase volume and inner space, light portable.
