New Description: [New Technology Field] This creation is about a bicycle, especially with a power subsidy package that can provide a driving force for driving the bicycle forward. [Prior Art] A bicycle is a kind of vehicle, which mainly has a frame to appeal to a front wheel and a rear wheel of the frame, and a front key wheel and two links with the rear wheel. a rear sprocket, the chain connecting the front and rear sprocket, and the rider pedaling with the two feet to drive the front key wheel and driving the rear wheel to rotate the bicycle by the key strip, the driving behavior It is not difficult for the average user, but for a specific user or for a specific use situation (such as an elderly, frail user or riding in a ramped environment), The bicycle advancement system has a certain degree of difficulty. In order to solve the above problem, there is a power assist device that can provide driving force by electric power and can assist the user to drive and drive forward. 31 There are a wide variety of power assist devices, which use the motor as the power source, and rely on the 、., the soil Wei 仏 low motor to drive the bicycle can be mainly divided into the types of the species: such as the invention patent notice 1301467 No. disclosed in the above, wherein the motor is mounted on the wheel of the front wheel or the rear wheel of the soap, and the front wheel or the rear wheel of the front wheel is directly driven. 2. If the new type is free, it is disclosed in the above-mentioned M305 799, in which the motor system is placed on the rear side of the bicycle and connected to the rear sprocket by a chain or belt M357420 or the like. The transmission member transmits the third force as disclosed in the new patent publication No. M328416. The sprocket is disposed adjacent to the front sprocket of the bicycle and transmits the driving force by means of a 傕: a horse chain or a belt material is coupled to the front sprocket. The transmission member is described in one way, although it can effectively transmit the brake on the motor. However, the structure of the bicycle body must be made to change the "connected with the motor", so the power assisted skirt: Today, fortunately In the second and third modes mentioned above, the position is two more, which will result in difficulty in balancing when riding, and the chain or belt used to transmit power may cause the power assist device to lose its effectiveness. Luozhi’s bicycle still has room for improvement. #的,有动力助装 [New content] In view of the above-mentioned shortcomings of the existing bicycle with power assist device, this creation is made up of Pang Guben 1 and Car 11 n-bike, which can be directly installed for use. The power assisting device for solving the problem of falling off is expected to have the above-mentioned lack of the above-mentioned bicycles with the power assisting device. The technical means used in the creation is "supply-with power assist". The shocked bicycle comprises: a frame and a front sprocket disposed under the frame; a power assisting device comprising: a raking device having a motor and a reduction gear set, M357420 wherein the motor is used Providing a driving force disposed on a bottom side of the frame adjacent to the front sprocket, and the reduction gear set is coupled to the motor and the front sprocket to slow down a driving speed of the motor and to drive the driving force Passing to the front key wheel; a control unit electrically connected to the motor to control the rotation speed thereof; - a power supply device for supplying power for driving the device, It is disposed on the frame. • The power assisting device does not need to change the structure of the bicycle body during installation, so it can be applied to existing bicycles. In addition, the present invention is stable because it uses gears to transmit power. The transmission of power to the key wheel without the existing bicycle with the power assist device causes the power assist device to fail due to the failure of the chain or the belt to transmit the power, thereby failing to drive the bicycle forward. [Embodiment] See first and As shown in the second figure, the present invention is a bicycle with a power assist device. The first embodiment includes: a frame (60), a steering device (61) located in front of the frame (6 inches), and a vehicle. The __ front sprocket (62) under the frame (6G), the interconnected rear of the frame (6Q), the rear wheel (63) and the rear sprocket (64), and the front and rear sprocket (64) a linked chain (65); a power assisting device comprising: ^ a driving device (10) having a motor (u) and a deceleration π wheel, and (12), wherein the motor (丨1) ) to provide a driving force The arrangement is fixed to the bottom side of the frame (60) adjacent to the front sprocket (62), as shown in the figure, the 5 M357420 is placed on the lower frame of the frame (60), with reference to the third and As shown in the fourth figure, the reduction gear set (12) is disposed between the motor (11) and the front sprocket (62), and includes a first wheel (121) and a last wheel (122) respectively. (Π) interlocking with the front sprocket (62), the reduction gear set 〇2) can be driven by the motor (n) and slow down the rotation speed of the motor (11) before transmitting the driving force to the front sprocket (62) to drive it Rotating 'in this embodiment, a gear disc (21) is coupled to one side of the front sprocket (62), and the last wheel (122) is engaged with the gear disc (21); a control unit, The motor (11) is electrically connected to control the rotation speed of the motor (11). In this embodiment, the control unit includes a speed control handle (31) and a controller (32) electrically connected. The speed control handle (31) is disposed on the steering device (61), and the controller (10) is disposed on one side of the motor (11), and is controllable by rotating the speed control handle (31) a motor (ιι) rotational speed; an electric device (40) for supplying the driving device 〇〇) a power source for operation. In the present embodiment, it is disposed on the rear side of the frame (6〇) and is coupled to the motor (11) and the control unit is electrically connected. The wheel set (12) is driven to rotate by the motor (1), and the wire disc (9) together with the front sprocket (62) (four), (4) the front sprocket (4) simultaneously drives the chain (65) (four) rear sprocket ( 64) Rotating with the rear wheel (63), so as to achieve the purpose of driving the bicycle by itself (11}. The reduction::: See the fifth figure. In the second embodiment of the present creation, the round: The heart is present;: (:) The wide wheel (122) can be provided with a ratchet (123) to allow the end to rotate freely: and can be freely rotated in the direction in which the rear wheel (63) is rotated, so that the present embodiment can be When the door is exhausted and the motor ((1) is damaged, causing the reduction gear set ^40), the power consumer wants to drive the bicycle forward with his own power,) the second = the use of ..., the cost of the gas belt 6 M357420 dynamic group reduction gear set ( i 2 ) and the motor (丨丨) turn to rotate the front sprocket (6 2 ). Further referring to the sixth and seventh figures, a third embodiment of the present invention further includes a hollow casing (51) and at least one bracket (52) coupled to the casing (51). A shaft hole (521) is formed in the bracket (52), and the bracket (52) is sleeved by the shaft hole (521) and fixed on the five-way tube (66) of the frame (6). The driving device (1〇) is disposed in the casing (51) and is in conjunction with the gear plate (21). Referring to the eighth figure, in the embodiment, the frame (5〇) When the casing (51) is mounted on the upper part, the five-way pipe (66) can be set as the shaft-to-finished body (5 1), and the technical means can increase the selectivity of the installation to facilitate the actual installation.
