Description

  The present invention relates to a folding electric bicycle.

  Traditional electric bicycles have a fixed frame and take up space for storage. For this reason, an electric vehicle capable of folding the front frame and the rear frame is provided in response to the problem of narrowness in the living space of modern people, and its rough structure is as shown in FIG. This electric bicycle A1 is attached to the front side of the frame A11, the front wheel A12 and the rear wheel A13 which are assembled to the bottom end of the frame A11 and corresponding to the front and rear, the saddle A14 at the upper end of the frame A11, and the front of the frame A11 and controls the direction. Handlebar A15 is provided. Among them, the frame A11 includes a connecting device A16 located between the front wheel A12 and the rear wheel A13, and the frame A11 can be folded, so that the connecting device A16 includes a corresponding front rod A161 and rear rod A162. A folding mechanism A17 is assembled between the front rod A161 and the rear rod A162 that are configured and connected to each other.

  By controlling the folding mechanism A17, the electric bicycle A1 can achieve the folded state. As shown in FIG. 1, the existing folding electric bicycle A1 includes the front rod A161 and the rear rod of the connecting device A16. The 162 foldable design can reliably reduce the total space volume after folding the electric bicycle A1, thereby achieving the purpose of being convenient for storage and not taking up space. However, such a folding method only folds the vehicle body length of the electric bicycle A1, and the saddle post that supports the saddle A14 cannot be folded, and still occupies space. In addition, when the electric bicycle A1 is folded and then moved, its front wheel A12 comes into contact with the rear wheel A13. At this time, the rear wheel A13 and the front wheel A12 are in contact with each other, and the positions of the two wheel shafts are The wheel axle of the rear wheel A13 is shifted and protrudes into and enters the front wheel A12. Therefore, the electric bicycle A1 cannot be easily towed by driving the wheel, and cannot be moved unless the electric bicycle A1 is lifted from the ground. , Forming inconvenience after the user folds, and force is applied.

Crank (43), convex shaft portion (44) pivoting the rear end (22) of the connecting frame (2) to the front end of the rear frame (4), the left rod frame (40), the right rod frame (41) A saddle post (45) fitted to the front end and projecting upward, and a saddle (46) at its upper end. Among them, the left rod frame (40) and the right rod frame (41) are respectively a convex shaft portion (44) fitted to the rear end (22) of the connecting frame (2) and the sides of the convex shaft portion (44). Is provided with an engagement block (48) that is pivotally mounted to the shaft rod (47), and the engagement block (48) has an L shape, and the shaft rod (47) of the engagement block (48). ) Is provided with a hole (480).

  The positioning set (5) (see FIG. 6) is attached to the connecting rod (6) between the left rod frame (40) and the right rod frame (41) of the rear frame (4) in a lateral direction, and the positioning set (5 ) Comprises a frame (50), a positioning pulling rod (51) pivoted inside the frame (50), a spring (52) mounted around the positioning pulling rod (51), and a positioning pulling rod (51). Is moved back and forth in the frame (50) by the compression elasticity of the spring (52), and the positioning pulling rod (51) is attached to the side of the frame (50) and protrudes outside the side of the frame (50). The positioning snap ring (53) on the side of the frame (50) is fixed and the positioning pulling rod (51) is located on the connecting rod (6) and pivotally connects the connecting frame (2) and the rear frame (4). It corresponds to the hole (480) of the engagement block (48) located below the convex shaft portion (44) and pivoted on the side of the convex shaft portion (44) by controlling the end of the positioning pulling rod (51). And thus the positioning of the rear frame (4) is achieved, whereby the purpose of moving the rear frame (4) between the deployed position and the folded position is achieved, and the positioning pull bar (51) and the hole ( The front wheel (32) and the rear wheel (42) can be moved inward by the locking and disengagement of 480).

  The connecting rod (6) is passed between the left rod frame (40) and the right rod frame (41) of the rear frame (4), the support shaft (610) of the front end (61), and the lower end of the front frame (3). The arc-shaped convex mass (31) is pivoted, the rear end is connected to the saddle post (45), and the connecting support shaft (62) is provided between the connecting rod (6) and the rear frame (4). Yes.

  In the present invention, in order to achieve the purpose of stationary positioning when the electric bicycle (1) is in the folded state, an auxiliary wheel (430) is pivotally connected to the end of the crank (43) on both sides of the rear wheel (42) of the rear frame (4) Then, the auxiliary wheel (430) and the rear wheel (42) are positioned on the ground (7) with the same horizontal plane, the folded electric bicycle (1) can be left in a fixed position, and the vehicle body can be stabilized during movement. .

  Please refer to FIGS. When the electric bicycle (1) of the present invention is folded and stored, first, the positioning pulling rod (51) is first inserted and inserted (FIG. 6), and further pulled out toward one side, and the spring ( 52) is compressed so that the positioning pull rod (51) and the hole (480) of the engagement block (48) are separated (FIGS. 7 and 8). At this time, if the saddle (46) is lifted by hand, the shaft rod (47) of the convex shaft portion (44) between the rear frame (4) and the connecting frame (2) moves upward, and the rear frame (4 ) And the connecting frame (2) are bent inward. At the same time, the front wheel (32) and the rear wheel (42) move inward in synchronization. Further, when the positioning pull rod (51) is positioned in the engagement hole (211) of the engagement piece (212) of the support shaft (210) of the front frame (3), the folding of the electric bicycle (1) is completed ( 9 and 10). On the other hand, when riding on the electric bicycle (1), the above steps are repeated and the front frame (3) and the rear frame (4) are used as the unfolded positions. After connecting the rod (47) to form a straight line, the end of the positioning pulling rod (51) is further fitted into the hole (480) of the engagement block (48) fitted to the convex shaft portion (44). That's fine.

  When the rear frame (4) is in the deployed position, the rear wheel (42) of the rear frame (4) and the front wheel (32) of the front frame (3) are positioned on a horizontal plane, and the auxiliary wheel in the crank (43). (430) is not in contact with the ground (7). When the rear frame (4) is in the folding position, the articulated frame (2) and the rear frame (4) have a bent shape with the shaft rod (47) of the convex shaft portion (44) as a fulcrum. The connecting rod (6) is driven to rotate downward, and the rear frame (4) and the rear wheel (42) approach the front wheel (32) of the front frame (3). At this time, the auxiliary wheel (430) and the rear wheel (42) are on the same horizontal plane and supported on the ground (7) (FIG. 11), and assist the movement of the electric bicycle (1) after positioning and folding.

  In summary, the present invention uses the convex design (44) between the connecting frame (2) and the rear frame (4) to fold the connecting rod (6), thereby reducing the space volume after folding the electric bicycle (1). By setting the crank (43) smaller than the electric bicycle A1, the auxiliary bicycle (430) of the crank (43) and the ground (7) are brought into contact with each other when the electric bicycle (1) is folded. ) Convenient for positioning after folding. Thus, when the user moves, the auxiliary wheel (430) on both sides of the rear wheel (42) can move the vehicle body in a calm manner, stabilize the vehicle body, and lift the electric bicycle (1) when storing it. It can be transported easily.
