Referring to FIGS. 1 to 5, a machinery 10 is provided with a control unit 11, a display unit 12, and a connection unit 13, wherein the control unit 11 is electronically connected with the display unit 12 and the connection unit 13 to provide for tuning an FM station to play and for connecting to a digital music walkman (iPod), the control unit 11 includes a plurality of control keys 111 (such as a power on/off key, a channel tuning key, a channel switch key, etc.) and a control circuit 112, the display unit 12 is an LCD (Liquid Crystal Display) screen, and the connection unit 13 is provided with a connection seat 131 and a connector 132. A bottom of the connection seat 131 is provided with an opening 133 for providing a transfix of the connector 132, an end of the connection seat 131 is provided with at least one ridge 134, and the other end of connection seat 131 is provided with a concaved part 135. In addition, the machinery 10 is installed with a slot 101 corresponding to the connection seat 131 to provide for an emplacement of the connection seat 131. An end of the slot 101 is provided with a through-hole 102 to provide for a transfix of the corresponding ridge 134 of the connection seat 131, and the other end of slot 101 is provided with an elastic locking member 103 to be loosely positioned and assembled with the concaved part 135 at the other end of connection seat 131. An outer rim of the connection seat 131 is formed with an extension part 136, and an upper rim of the slot 101 is correspondingly formed with a grading part 104 to enable the connection seat 131 to be loosely positioned and assembled with the slot 101 of machinery 10.
A loose positioning seat 20 is assembled with the machinery 10 and comprises a seat body 21 and a driving positioning set 22. An interior of the seat body 21 is installed with a block 211, a periphery of the block 211 is partitioned into containing slots 212, and a periphery of the seat body 21 is formed with a plurality of opening slots 213. The driving positioning set 22 is loosely assembled with a gear 221 on the seat body 21, and the gear 221 is gnawed with a plurality of positioning members 222 (wherein, an inner side of the positioning member 222 is provided with an extension section 225 on which is installed with a teeth part 226 for enabling the gear 221 to be gnawed with the positioning member 222) below each of which is installed with a pillar 223 on which is sheathed with an elastic member 224, with one end of each elastic member 224 being transfixed into the containing slot 212 at the periphery of block 211 for enabling each positioning member 222 to be loosely positioned.
Moreover, the loose positioning seat 20 is also composed of a cover 23 which is assembled between the seat body 21 and the machinery 10. A bottom of the cover 23 is provided with a projection part 231 on which is installed with a projection piece 232, and the extension section 225 of the positioning member 222 is correspondingly provided with a guiding slot 227 for enabling the positioning member 222 to be loosely positioned and sliding. In addition, a center of the projection part 231 at the bottom of the cover 23 is installed with a sheath part 233, and the cover 23 is provided with a plurality of opening slots 234 which are corresponding to a plurality of ridges 214 installed on the seat body 21, so as to correspondingly sheath the plural opening slots 234 on the cover 23 with each ridge 214 on the seat body 21. On the other hand, the sheath part 233 of cover 23 is sheathed on an axis of the gear 221 on the seat body 21, so as to facilitate the cover 23 to be positioned and assembled with the seat body 21.
Referring to FIGS. 1 to 6, a multimedia device is constituted by the aforementioned structures. By a design which assembles the machinery 10 and the loose positioning seat 20, the machinery 10 can be quickly and firmly positioned and assembled with all kinds of cup racks 30 in a vehicle by the loose positioning seat 20. In addition, by a design which assembles the seat body 21, the driving positioning set 22, and the cover 23 of loose positioning seat 20, the loose positioning seat 20 can be formed into the design of perfect driving and robust positioning. Furthermore, by a control unit 11 which is installed on the machinery 10 and is electronically connected with the display unit 12 and the connection unit 13, by the plural control keys 111 (such as the power on/off key, the channel tuning key, the channel switching key, etc.) which are installed on the control unit 11 for controlling the power on/off of the machinery 10, selecting the FM station to play, and quickly switching the channel, respectively, and by the connection seat 131, the connector 132, a power socket, and an audio socket, which are installed on the connection unit 13, the machinery 10 can be connected to a digital music walkman (iPod) and is provided with a charging function. Moreover, by the slot 101 which is installed on the machinery 10 to correspond to the connection seat 131 for emplacing the connection seat 131, and by the design of connection seat 131 which can be loosely assembled with the machinery 10, a connection seat of different style can be replaced freely, thereby enabling the present invention to be provided with the effects of easy and quick to assemble, robust to position, and convenient to carry and use, as well as to be provided with an improvement of a practicability and convenience of the entire device.
It is of course to be understood that the embodiments described herein is merely illustrative of the principles of the invention and that a wide variety of modifications thereto may be effected by persons skilled in the art without departing from the spirit and scope of the invention as set forth in the following claims.
