Description

Emergency power supply device for vehicle

Technical Field

The utility model relates to an electromechanical field, in particular to can provide great generated power output's manual power generation facility.

Background

Many emergency power generation devices have been designed to provide electrical power for emergency use by hand or hand. For example, the application number 201720455072.4 entitled "hand-operated automobile starting emergency power supply" provides a device which adopts a hand-operated generator to match with a super capacitor to meet the requirement of automobile low-voltage power supply starting in a short time. In the emergent occasion that the power demand is great, the emergent power generation facility that has jumbo size crank can satisfy the power user demand, but great crank carries inconveniently. The small-size hand-operated power generation equipment or hand-held power generation equipment is relatively convenient to carry, but the generated power is usually small due to the volume limitation, so that the emergency requirement of large power for starting the automobile is difficult to meet; or the handle is small and inconvenient to apply, which is easy to cause fatigue of the user.

In order to solve the problems, the hand-pulling rope is adopted to drive the generator to rotate to generate electricity, which is a potential alternative. To achieve this, the manual power generator of application No. 95244486.0 proposes an embodiment in which a hand-pulling rope is used to drive a winding drum to rotate, a volute spring is used to retract the rope on the winding drum, and a mechanism capable of unidirectional torque transmission is used to keep the generator in the same rotation direction. Similarly, a coil spring, a ratchet wheel and a winding drum with a pull wire are considered to be matched together in a plurality of patent applications, so that the aim of driving the generator to rotate in one direction is fulfilled. For example, the manual power small generator of application No. 01267953.4, the manual power multifunctional charger of application No. 03225620.5, the manual power self-generating charger of application No. 200320116825.7, the manual power generator of application No. 200620017645.7, the manual power generating device of application No. 200720058124.0, and the like.

All these designs have in common the idea of keeping the generator rotating in a single direction relatively stable. However, the ratchet wheel or the similar one-way transmission mechanism has the defects of large friction loss and easy failure and damage, so that the design schemes adopting the one-way transmission mechanism have large failure risks when being used in emergency occasions, and the design schemes deviate from the requirement of needing a highly reliable power supply in the emergency occasions.

The automobile emergency starting device with the application number of 201510346776.3 comprises a super capacitor bank, a generator and an external force driving power generation device; the super capacitor bank is electrically connected with the generator; the rotating shaft of the generator is connected with an external force driving generating set; the external force driving power generation device is used for driving the generator to generate power; the super capacitor bank is used for storing electric energy generated by the generator. The external force driving power generation device comprises a bottom plate, a pedal plate, a generator driving device and a driving spring; wherein the pedal plate drives the generator through the generator driving device; the generator is arranged at one end of the bottom plate, and the upper surface of the other end of the bottom plate is provided with a spring mounting hole; one end of the driving spring is arranged in the spring mounting hole, and the other end of the driving spring is connected with the lower surface of the pedal plate. The device is simple to use, but the generator in the device has sudden starting and stopping motion impact in a pedal working mode, and the gear rack device in the generator driving device is high in damage risk.

The driven wheel 17, the main driving wheel 14 and the auxiliary driving wheel 15 are matched gears, the main driving wheel 14 and the reel 16 are coaxial, the reel 16 can drive the main driving wheel 14 to rotate when rotating, the main driving wheel 14 and the auxiliary driving wheel 15 are also matched gears, and the auxiliary driving wheel 15 can be driven to rotate reversely when rotating; the middle section of the wire 18 is wound with a plurality of single-layer rings on the reel 16, both ends of the wire extend out from the same side of the driving wheel bracket 13 at angles parallel to each other after passing around pulleys 20 located at both ends of the driving wheel bracket 13, and both ends of the wire have the pull rings 19; the driving wheel bracket 13 is mounted on a shaft of the base 11, which is parallel to the axial direction of the generator 10, and can rotate around the shaft; the main driving wheel 14 and the auxiliary driving wheel 15 are both mounted on the driving wheel bracket 13, and when any side of the driving wheel bracket 13 is close to the generator 10 to a proper distance, the main driving wheel 14 close to one side or the auxiliary driving wheel 15 close to the other side can be respectively matched with the driven wheel 17, and the driven wheel 17 is driven to rotate when rotating.

To illustrate the operation mode of the power generation module, the operation condition that the auxiliary driving wheel and the driven wheel are engaged to drive the generator when the cord on one side of the auxiliary driving wheel is pulled out is shown in fig. 3. As illustrated in the figure, when the wire 18 on one side of the secondary driving wheel 15 is pulled out, the driving wheel bracket 13 rotates clockwise by a certain angle because the wire 18 generates a clockwise moment on the driving wheel bracket 13 through the pulley 20, and the upper secondary driving wheel 15 is engaged with the driven wheel 17.

As described above, the rotor of the generator 10 can continue to rotate in the clockwise direction while the both ends of the wire 18 are alternately and repeatedly pulled out.
