New description: [New technical field] This creation is related to electric assist bicycles, especially regarding a battery device for electric assist bicycles. [Prior Art] As the leisure trend of riding bicycles is booming, and some users use bicycles as commuter means of commuting to work, the quality of bicycles is increasing and the types are increasing. In order to cater to the different needs of users and to provide the convenience and convenience of riding a bicycle, electric bicycles are one of the options. When the user rides, the sensor of the electric assist bicycle senses the force of the user's pedaling to provide the predetermined power, so that the electric assist bicycle can obtain the driving force by the user's pedaling force and the assistance provided by the user. In this way, the electric assist bicycle does not cause too much load on the user's physical strength, and allows the user to achieve the purpose of fitness in addition to leisure. In the conventional art, the position where the battery is installed will have various options according to the structural design of the electric bicycle. For example, Chinese Patent No. CN1049631C discloses a battery loading and unloading structure of a power-assisted bicycle, which mainly fixes the baffle. After the tube is tilted under the frame, and then the battery case is fitted into the recess of the baffle, the battery case is fixed by a locking device. However, although the shape of the recess of the baffle and the shape of the battery case cooperate to allow the battery case to be fully fitted into the recess of the baffle, the baffle does not provide any structure for fixing the battery case. , the battery box is only fixed to the baffle by means of a locking device. As a result, the battery case is easily released when the electric assist bicycle is walking on a bumpy road surface. [New content] The main purpose of this creation is to provide a battery device for an electric assist bicycle, which can provide a good fixing effect of the battery case. In order to achieve the above object, the battery device of the present invention comprises a battery wide and a battery case. The battery holder has a bottom wall, an end wall and two side walls.

The σ and the guides can be provided by the engagement between the guide block of the battery case and the guide groove of the battery holder, and the fitting between the convex portion of the battery case and the groove of the battery holder. The battery case has a good fixing effect and achieves the purpose of this creation. [Embodiment] The following preferred embodiments are listed in conjunction with the drawings to explain the structure and function of the present invention in detail. Please refer to the first figure, which is a battery device (10) for an electric assist bicycle according to a preferred embodiment of the present invention, comprising a battery holder (20) and a battery (3 〇). M378150 Please refer to the second figure. The battery holder (20) has a bottom wall (21), an end wall (22), and two opposite side walls (23). The bottom wall (21) is fixed to one of the frame (1) of the electric assist bicycle; the end wall (22) is connected to the front end of the bottom wall (21) and forms a groove (24) with the bottom wall (21). The two side walls (23) are oppositely connected to the rear end of the bottom wall (21), and the inner side surfaces of each side wall (23) have a downwardly extending guide groove (25). The guide groove (25) has a straight line segment ( 252) with a half circular segment (254). The battery case (30) has a case (32) and a positioning member (34). The front end of the casing (32) has a convex portion (322), and the convex portion (322) can be inserted into the groove (24) of the battery holder (2), and the top end of the clamping member (34) is provided by a first A pivot shaft (36) is pivotally connected to the rear end of the casing (32), and a torsion spring (38) is mounted on each end of the first pivot shaft (36) to enable the positioning member (34) to receive the two torsion springs (38). The action is to pivot in the direction of the casing (32), and the two sides of the bottom end of the positioning member (34) respectively have a semi-circular guide block (342). The guide block (342) can cooperate with the guide groove (25) The semicircular segment (254) is snapped into the semicircular segment (254). When the battery case (30) is to be assembled to the battery holder (2〇), as shown in the second figure, 'the first guide block (342) of the battery case (30) is slid into the guide groove of the battery holder (2〇) ( 25) in the straight line segment (252), and pressurize the battery case (3〇), except that the convex portion (322) of each body (32) is inserted into the recess (24) of the battery holder (20), Then, the guide block (342) of the battery case (30) is slid down along the straight line segment (252) of the guide groove (25) until the guide block (342) is engaged with the semicircle of the guide groove (25). The segment (254), as shown in the second figure, 'the positioning member (34) at this time will slightly rotate away from the direction of the casing (32), thus completing the battery case (30) and the battery holder (2〇). Ambulance between the two. When the battery case (30) is to be removed from the battery holder (2〇), the force is applied to pull the case (32)' until the pulling force of the application box (32) overcomes the semicircular guide block (34 5 The friction between the semicircular section (254) of the guide groove (25) allows the guide block (342) of the battery case (30) to leave the guide groove (25) of the battery holder (20), and then The battery case (30) can be removed by pulling the convex portion (322) of the case (32) away from the recess (24) of the battery holder (20). In order to increase the anti-theft effect of the battery case (30), the creation The battery device (10) further provides a locking device (40), as shown in the fourth figure. The locking member (4〇) is pivoted to the battery holder (2〇) by a second pivot (5〇) The rear end of the bottom wall (21) has a hook portion (42) and can be hooked into one of the hooks (344) of the positioning member (34) by the hook portion (42) to fix the battery case (30) to the battery holder. (2〇); in addition, a torsion spring (52) is respectively mounted on both ends of the second pivot shaft (50), so that the locking member (4... can be subjected to the action of the δ Xuanyi torsion spring (52) to allow the hook portion (42) to The hook groove (344) is kept in a state of being hooked together. Thereby, the battery case (3〇) is pressed down until the guide block pc) of the battery case (3〇) is engaged with the guide groove (25). In the circular section (254), the hook (10) of the piece (4〇) ^ is hooked on the hook groove of the clamp (4) (in the 34 sentences, the battery case (π) is fixed to the battery holder (2G) and cannot be When removing the battery case (10), it is necessary to insert the key into one of the key holes (26) of the battery holder (10) and then rotate it to force the locking member (40) to deflect and let the hook (4) be disengaged from the positioning member (4). The slot (344) can smoothly remove the battery case (3〇). As can be seen from the above, the battery device of the present invention is engaged with the battery between the guide block of the battery case and the guide groove of the battery holder and the battery. The embedding between the convex portion of the box and the recess of the battery holder allows the battery case to be mounted on the battery holder to obtain a good mouth-hanging effect without being easily detached from the battery holder, so as to achieve the purpose of the creation. The constituent elements disclosed in the foregoing embodiments are merely illustrative and are not intended to limit the scope of the present invention, and alternatives or variations of other equivalent elements are also covered by the scope of the patent application of the present application.
