DETAILED DESCRIPTION
The present invention will be clearer from the following description when viewed together with the accompanying drawings, which show, for purpose of illustrations only, the preferred embodiment in accordance with the present invention.
Referring to FIGS. 1-6, a mobile power pack 20 in accordance with the preferred embodiment of the present invention is to be fixed in a steering pipe 10 of a bicycle. The steering pipe 10 includes a first receiving chamber 11 with an open end 12.
The mobile power pack 20 includes a housing 21, a quick lock device 22, a fixing assembly 23, a mobile power source 24 and a cover 25.
The housing 21 includes a second receiving chamber 210. At the top of the housing 21 is formed an outer threaded portion 211, and at the bottom of the housing 21 is a connecting portion 212 which includes a connecting hole 2120 in communication with the second receiving chamber 210.
The quick lock device 22 includes a quick release member 220 and an elastic member 221. The quick release member 220 includes a plurality of quick release blocks 2200. At a center of each of the quick release blocks 2200 is formed an arc-shaped groove 2201, and the elastic member 221 is received in the arc-shaped groove 2201 to clamp the quick release blocks 2200 together.
The fixing assembly 23 includes a first fixing member 230 which is provided with an outer threaded section 2300, and a second fixing member 231 which is provided with an inner threaded hole 2310 for meshing with the outer threaded section 2300.
The mobile power source 24 is electrically connected to an electric operating portion 240 which includes an output port 2400 and an input port 2401 which are electrically connected to the mobile power source 24.
The cover 25 includes an inner threaded portion 250 for meshing with the outer threaded portion 211 of the housing 21.
In assembly, the housing 21 is placed in the first receiving chamber 11 of the steering pipe 10, then the quick lock device 22 is mounted on the connecting portion 212 of the housing 21, the first fixing member 230 is inserted through the second receiving chamber 210 and exposed out of the connecting portion 212 to lock with the quick lock device 22, and the outer threaded section 2300 of the first fixing member 230 is screwed in the inner threaded hole 2310 of the second fixing member 231.
After that, a tool T is inserted in the second receiving chamber 210 of the housing 21 to rotate the first fixing member 230 until the outer threaded section 2300 of the first fixing member 230 is screwed in the inner threaded hole 2310 of the second fixing member 231. The first fixing member 230 is pushed against the quick lock device 22, and the quick release blocks 2200 of the quick lock device 22 are pushed outwardly by the first fixing member 230 to press against the inner surface of the steering pipe 10, so that the mobile power pack 20 is fixed in the first receiving chamber 11 of the steering pipe 10 by the housing 21.
Finally, the mobile power source 24 is put into the second receiving chamber 210 of the housing 21, and then the inner threaded portion 250 of the cover 25 is engaged with the outer threaded portion 211 of the housing 21, so that the mobile power pack 20 is assembled onto the steering pipe 10.
When the mobile power pack 20 is fixed onto the steering pipe 10, the output port 2400 of the electric operating portion 240 can be provided for connection of various external 3C products, which makes the bicycle more practical. When the mobile power source 24 runs out of power, it can be recharged by connecting external power source to the input port 2401.
If the mobile power source 24 is out of use, the rider can use the tool T to reversely rotate the first fixing member 230 to make the outer threaded section 2300 move out of the inner threaded hole 2310 of the second fixing member 231, then the quick release blocks 2200 of the quick lock device 22 will retract to leave a space S between the quick release blocks 2200 and the inner surface of the steering pipe 10, so that the mobile power source 24 can be pulled out from the housing 21 and replaced with a new mobile power source 24.
The mobile power pack 20 fixed in the steering pipe 10 of the bicycle has the following advantages:
The output port 2400 of the electric operating portion 240 can be provided for connection of various external 3C products, such as mobile phone, personal stereo or ipad, which allows the riders to enjoin music while riding, or to watch film when not riding.
When the mobile power source 24 runs out of power, it can be recharged by connecting external power source to the input port 2401.
The mobile power source 24 is placed in the housing 21, so that the housing 21 can protect the mobile power source 24 from water when riding in a rainy day.
The cover 25 is screwed to the electric operating portion 240 and fixed to the housing 21, and only removed when it needs to connect a 3C product or recharge the mobile power source 24. Therefore, the cover 25 can protect the mobile power source 24.
The connecting portion 212 includes a connecting hole 2120 in communication with the second receiving chamber 210, and the second fixing member 231 includes the inner threaded hole 2310. If water accidently comes into the second receiving chamber 210 of the housing 21, it can be drained from the connecting hole 2120 and the inner threaded hole 2310, so as to avoid wetting the mobile power source 24.
While we have shown and described various embodiments in accordance with the present invention, it is clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
