Chargeable electric winch

The invention relates to a chargeable electric winch, and more particularly to a portable winch using a chargeable battery so that the winch can be used at a place where no power can be obtained or the power cannot be easily obtained. Forexample, the chargeable electric winch can be used to spread a canvas of a sailing boat and to put the canvas of the sailing boat together, or to hang a heavy object in the farm.
At a place where no power can be obtained or the power cannot be easily obtained, a winch is typically driven by a hand of a user in a time-consuming and labor-consuming manner. The following examples will be described.
In a first example for a water activity, the winch has to be used on a sailing boat or a yacht in order to coil and uncoil a cable, to spread a canvas and to put the canvas together, and to change the moving direction of the canvas. However, thepower cannot be obtained or cannot be easily obtained on the sailing boat or the yacht, and the manual winch is usually used to control these operations so that these operations are time-consuming and labor-consuming operations.
In a second example for a land activity, the winch has to be used in a high mountain, in a forest or in a farm to hang up a heavy object, to move the heavy object away or to coil and uncoil the heavy object. Because the power cannot be obtainedor cannot be easily obtained in the high mountain, the forest or the farm, and the manual winch is usually used to control these operations so that these operations are time-consuming and labor-consuming operations. The land activity also has theproblem that the power cannot be obtained or the power cannot be easily obtained. In addition, a net in a tennis court is usually lifted up and lowered down by the manual winch.
Thus, it is an important subject of the invention to provide a chargeable electric winch capable of solving the above-mentioned problems in a reasonable and effective manner.
It is therefore an object of the invention to provide a chargeable electric winch, which is portable and uses a chargeable battery so that the chargeable electric winch can be conveniently carried and operated. In addition, the battery makes thewinch be used at a place where no power can be obtained or the power cannot be easily obtained so that the timesaving and laborsaving effects can be obtained as compared with the conventional manual winch.
Another object of the invention is to provide a chargeable electric winch having a battery which is separatably assembled with a housing so that the battery can be replaced with another backup battery. More particularly, a connector can beconnected to an opposite connector as the battery is assembled with the housing so that the battery can provide the power through the connectors.
Still another object of the invention is to provide a chargeable electric winch having a driven shaft which may be combined with different opposite elements according to different requirements. The light emitting angle of the lighting element isconfigured such that the light is emitted toward a free end of the driven shaft. Thus, the better illumination effect may be obtained. In addition, the position of the handle is close to the driven shaft so that the orientation of the free end of thedriven shaft can be controlled more conveniently and more precisely.
To achieve the above-identified objects, the invention provides a chargeable electric winch for driving a to-be-controlled object to rotate. The electric winch includes a housing, a driving device, a driven shaft, a first switch and a battery. The driving device is disposed in the housing. The driven shaft penetrates through the housing and is driven by the driving device to rotate. The first switch is disposed on the housing and has a controller. The controller has an opposite connectorand is electrically connected to the driving device. The battery has an inner battery body and an outer connector electrically connected to the inner battery body. The battery for providing power is electrically connected to the opposite connector ofthe first switch through the outer connector of the battery, and the battery is separatably assembled with the housing.
The invention has the following advantages. The chargeable electric winch of the invention is portable and can thus be carried and operated conveniently. The electric winch of the invention is powered by the chargeable battery so that theelectric winch can be used at a place where no power can be obtained or the power cannot be easily obtained, and the timesaving and laborsaving effects can be obtained as compared with the conventional manual winch. The driven shaft can be connected todifferent opposite elements according to the actual requirement. The light emitting angle of the lighting element is configured such that the light is emitted toward the free end of the driven shaft. Thus, the better illumination effect may beobtained. The position of the handle is close to the driven shaft so that the orientation of the free end of the driven shaft can be controlled more conveniently and more precisely. The battery is configured to be separatably assembled with the secondend portion of the housing so that the battery can be replaced with another backup battery. More particularly, the connection between the outer connector and the opposite connector can achieve the effect of creating the electrical connection between theouter connector and the opposite connector when the battery is assembled with the second end portion.
