The housing 110 has a first opening 112, a second opening 114, and a space 116, wherein the first opening 112 is situated at a side surface S of the housing 110, and the second opening 114 is situated on a top surface T of the housing 110.
In an embodiment of the present invention, the housing 110 comprises a first housing body 111 and a second housing body 113 connected with each other to form the space 116. Particularly, in this embodiment, the first housing body 111 has a plurality of locking buttons 111a, the second housing body 113 has a plurality of locking hooks 113a, and the second housing body 113 is fixed to the first housing body 111 by engaging the locking hooks 113a with the locking buttons 111a. 
It should be noted that the housing 110 of the present embodiment is composed of the first housing body 111 and the second housing body 113 being engaged with each other via the locking buttons 111a and the locking hooks 113a. However, the present invention provides no limit thereto. Any type of housing capable of accommodating the base and compatible with the aforementioned operating manner can further be applied in the present invention. In addition, the quantity of locking buttons 111a and the locking hooks 113a are not limited and may vary with the requirement of design of the housing.
The base 120 is movably disposed in the space 116 and provided with a slot 122 facing the second opening 114, wherein the profile of the base 120 substantially complies with the space 116 to allow the base 120 moving in the space 116. In this embodiment, the base 120 leans against the inner bottom surface of the first housing body 111 and moves in the space 116 with the restriction of two side walls of the first housing body 111.
However, in another embodiment of the present invention, the base 120 may be provided with a rail (not shown), and the first housing body 111 may be provided with a protrusion (not shown) corresponding to the rail, so that the base 120 can move in the space 116 via the couple of the protrusion and the rail. Therefore, the moving mechanism provided between the base 120 and the space 116 is not limited in the present invention. Any mechanism capable of allowing the base 120 moving within the space 116 should be considered as being in the scope of the present invention.
On the other hand, the base 120 is used for accommodating the storage device 130 which can be a flash memory storage device as illustrated in this embodiment. However, the present invention provides no limit to the type of the storage device 130. In another embodiment of the present invention, the storage device 130 can further be a read only memory (ROM) storage device or other applicable storage devices.
Furthermore, the connecting member 132 provides the function of electrically connecting the object in the base 120 with other electronic devices. In this embodiment, the connecting member 132 is provided with gold fingers (not shown) for electrically connecting the storage device 130 with other electronic devices to transmit data. In an embodiment of the present invention, the connecting member 132 can be but not limit to a universal serial bus (USB) plug. In another embodiment, the connecting member 132 may further be an IEEE 1394 plug or other applicable plugs. In further another embodiment not shown, the connecting member 132 can be an adapter plug connected with other electronic devices.
The rotating mechanism 140 is disposed at the second opening 114 and pivotably mounted to the housing 110. More specifically, in an embodiment of the present invention, the rotating mechanism 140 comprises a rotating disk 144 and a rotating lid 146, wherein the rotating disk 144 extends a coupling portion 144a passing through the second opening 114 and coupled with the rotating lid 146 to mount the rotating mechanism 140 to the housing 110. It should be noted that the present invention provides no limit to the connecting manner between the rotating mechanism 140 and the housing 110. Any applicable manner capable of driving the base 120 by the rotating mechanism 140 should be considered as being in the scope of the present invention.
In addition, in the present embodiment, the rotating mechanism 140 has a protrusion portion 142 movably engaged in the slot 122. Specifically, the protrusion portion 142 is located on a surface of the rotating disk 144 away from the rotating lid 146. In other words, the protrusion portion 142 is in the backside of the rotating lid 146 and faces the slot 122.
When the rotating mechanism 140 is rotated, the protrusion portion 142 moves along a circular path of the rotating mechanism 140 and drives the base 120 moving in the space 116 by the engagement with the slot 122. In an embodiment of the present invention, a diameter of the circular path of the protrusion portion 142 is 12 millimeters (mm) which complies with the standard minimum length (i.e. 11.75 mm) of the regulation of USB connecting member. Thus, a connecting member complying with the USB regulation can be retracted in or exposed out of the housing 110 by turning the rotating mechanism 140. The operation of shifting the base 120 by turning the rotating mechanism 140 accompanying with figures is illustrated below.
It is noted that, in the present embodiment, the slot 122 is situated on a top surface of the base 120 and facing the second opening 114, such that the protrusion portion 142 can be engaged in the slot 122. However, the present invention provides no limit to the position of the slot 122 on the base 120. Mechanisms capable of complying with the rotating mechanism 140 and the protrusion portion 142 thereof to drive the base 120 are preferred in the present invention.
FIG. 2 is a schematic view illustrating the flash drive and the housing assembly of FIG. 1 provided with a connecting member retracted in a housing. FIG. 3 is a schematic view illustrating the flash drive and the housing assembly of FIG. 1 provided with a connecting member exposed out of a housing. Referring to FIG. 1, FIG. 2 and FIG. 3, when the rotating mechanism 140 is rotated relative to the housing 110, the protrusion portion 142 moves in the slot 122, so as to transfer the rotation of the rotating mechanism 140 into a linear motion of the base 120 by the interference between the protrusion portion 142 and the slot 122. Therefore, the rotating mechanism 140 drives the base 120 to reciprocate between a first position A and a second position B, and when the base 120 moves from the first position A to the second position B, the connecting member 132 goes through the first opening 112 and is exposed out of the housing 110 for the flash drive 100 to be connected with other electronic devices. Furthermore, the rotating mechanism 140 can drives the base 120 from the second position B back to the first position A, by which the connecting member 132 is retracted and preserved in the housing 110.
In one embodiment of the invention, the housing 110 may further comprise a stopper 118. The stopper 118 is located in the space 116 for locating the base 120 in the first position A. However, the profile, quantity and arrangement of the stopper 118 are not limited in the present invention and depend on the profile of the base 120. Moreover, in another embodiment of the present invention, the housing 110 further comprises a locating bump 115 on the top surface T around the second opening 114, and the rotating mechanism 140 further comprises an indentation 141 corresponding to the locating bump 115, such that the locating bump 115 can be engaged with the indentation 141 to locate the base 120 on the second position B, by which a tangible operation feel can be provided as driving the rotating mechanism 140. Furthermore, the present invention provides no limit to the quantity and the arrangement of the locating bump 115 and the corresponding indentation 141 of the flash drive 100. In another embodiment of the present invention, two locating bumps are disposed around the second opening, wherein the two locating bumps are located at two opposite sides of the second opening and on the same diameter. When the base is located on the first position A or the second position B, corresponding indentations are respectively engaged with the two locating bumps. Therefore, a tangible operation feel can be provided as operating the flash drive.
Accordingly, the protrusion portion 142 of the rotating mechanism 140 and the slot 122 of the base 120 performs a relative motion and interferes with each other, such that the base 120 can be driven to reciprocate in the housing 110 by the rotation of the rotating mechanism 140. By which, the connecting member 132 can be exposed out of or retracted in the housing 110 according to the requirement in using. Hence, the flash drive 100 and the housing assembly according to the aforementioned embodiments meet the requirement of preserving the connecting member 132.
Furthermore, the rotating mechanism 140 can be turned clockwise or counterclockwise to drive the base 120 performing a linear reciprocation in the housing 110 without being limited by the direction or times of rotation.
FIG. 4 is an exploded view of a flash drive and a housing assembly thereof according to another embodiment of the present invention. Referring to FIG. 4, the difference between the flash drive 400 of the present embodiment and the flash drive 100 of the above embodiment is that the rotating lid 148 is shaped into a rectangular sheet. Other components of the flash drive 400 are similar to those of the aforementioned embodiments, and therefore descriptions of these components are omitted. In addition, it should be noted that the profile of the rotating lid 148 can be various according to different design concepts, and the present invention provides no limit thereto.
In summary, the flash drive and the housing assembly of the present invention is provided with a rotating mechanism and a base driven by the rotating mechanism to slide relative to the housing, and therefore when the flash drive is not in used, the connecting member can be preserved in the housing from being damaged as colliding with an external object. When using the flash drive, the user may rotate the rotating mechanism to drive the base and expose the connecting member out of the housing to connect other electronic device.
Furthermore, the protrusion portion of the rotating mechanism is engaged and interfered with the slot of the base, such that the rotation of the rotating mechanism can be transferred to the linear motion of the base. Whether the rotating mechanism rotates clockwise or counterclockwise, without being limited by the time of rotation of the rotating mechanism, the base can perform a linear reciprocation in the housing.
The previously described exemplary embodiments of the present invention have many advantages, including preserving the connecting member from being damaged as colliding with an external object, wherein the advantages aforementioned are not required in all versions of the invention.
It will be apparent to those skilled in the art that various modifications and variations can be made to the structure of the present invention without departing from the scope or spirit of the invention.
