The pressure cylinder 24A is supported by the housing 28 so as to be rotatable with respect to the support member 16 by key operation. The shell 28 is disposed within the 2 nd support member 20. The case 28 is attached to the No. 2 support member 20 by two bolts BT3, for example.
As shown in fig. 6, the cam mechanism 26 includes a1 st cam 26A and a2 nd cam 26B. The 1 st cam 26A includes a rod member extending in a rod shape. Specifically, the 1 st cam 26A is a columnar member arranged to extend in the 2 nd direction DY. The 1 st cam 26A is provided on an inner end surface (not shown) of the pressure cylinder 24A on the opposite side of the outer end surface 24C. The center axis CA1 of the 1 st cam 26A is offset from the center axis CA2 of the cylinder 24A. The center axis CA2 of the pressure cylinder 24A is coaxial with the rotation axis TR1 of the key unit. The rotation axis TR1 of the key unit is orthogonal to the 1 st direction DX, for example. In the present embodiment, the rotation axis TR1 of the key unit is along the 2 nd direction DY. The 1 st cam 26A is inserted into a groove 28A provided in the housing 28, for example, and is moved between both end portions of the groove 28A by key operation. The groove 28A has an outer shape along an arc centered on the rotation axis TR 1.
The 2 nd cam 26B is provided on the contact portion 25 so as to engage with the 1 st cam 26A. The 2 nd cam 26B includes a cam surface 26C that engages with the 1 st cam 26A. The cam surface 26C is a surface that converts the rotational motion of the 1 st cam 26A into linear motion. In the present embodiment, the cam surface 26C is a curved surface having a curved shape when viewed from a direction (2 nd direction DY) orthogonal to the 1 st direction DX. The 2 nd cam 26B is provided to the contact portion 25 such that the cam surface 26C extends in a direction intersecting the 1 st direction DX, for example. The 2 nd cam 26B may be integral with the contact portion 25 or may be separate from the contact portion 25. In the present embodiment, the 2 nd cam 26B is separate from the contact portion 25, and is attached to the contact portion 25 by a bolt BT 4.
The contact portion 25 includes a support surface 25A that supports a held portion 62 provided on the 1 st end surface 61A of the battery pack 60. In the present embodiment, the support surface 25A is the upper surface of the contact portion 25. The contact portion 25 is linearly moved by the operation of the 2 nd cam 26B based on the movement of the 1 st cam 26A. Specifically, the contact portion 25 is provided so as to be displaceable in the 1 st direction DX so as to insert the through hole 18B of the 1 st support member 18 therethrough. That is, the direction in which the contact portion 25 is displaced is orthogonal to the rotation axis TR1 of the key unit.
The contact portion 25 is provided so as to be displaceable between a1 st position capable of supporting the held portion 62 of the battery pack 60 via the support surface 25A and a2 nd position not supporting the held portion 62. The 1 st position indicates a position of the contact portion 25 when the contact portion 25 contacts the held portion 62 of the battery pack 60 so that the contact portion 25 holds the battery pack 60 at the 1 st holding position. The 2 nd position represents the position of the contact portion 25 when the contact portion 25 is separated from the held portion 62 so that the battery pack 60 can come out of the battery housing space DT1. The contact portion 25 protrudes from the 1 st supporting surface 18A of the 1 st supporting member 18 toward the 2 nd battery holder 32 through the through hole 18B in the state of being arranged at the 1 st position. The contact portion 25 is disposed at a position farther from the 2 nd battery holder 32 than the 1 st position in the state of being disposed at the 2 nd position. The contact portion 25 is disposed inside the 1 st battery holder 12 with respect to the through hole 18B in the state of being disposed at the 2 nd position. The contact portion 25 is biased to the 1 st position by a biasing member (not shown), for example. In one example, a biasing member (not shown) is provided between the contact portion 25 and the case 28 so as to bias the contact portion 25 from the 2 nd position to the 1 st position. The lock mechanism 24 shown in fig. 6 shows a state in which the contact portion 25 is disposed at the 1 st position. The lock mechanism 24 shown in fig. 7 shows a state in which the contact portion 25 is disposed at the 2 nd position.
The contact portion 25 and the 1 st end surface 61A of the battery pack 60 are configured to be less likely to interfere with attachment of the battery pack 60 to the battery holder 10. The contact portion 25 further includes an inclined surface 25B inclined with respect to the support surface 25A. The inclined surface 25B is configured such that the contact portion 25 is displaced to the 2 nd position by contacting the 1 st end surface 61A of the battery pack 60. Specifically, in the battery pack 60 mounted on the battery holder 10, the 1 st end surface 61A and the inclined surface 25B contact each other, and the contact portion 25 is displaced to the 2 nd position. Then, by releasing the contact between the 1 st end surface 61A of the battery pack 60 and the inclined surface 25B, the contact portion 25 is displaced to the 1 st position by a force received from a biasing member (not shown), and the held portion 62 of the battery pack 60 is supported by the support surface 25A.
With reference to fig. 6 to 8, removal of the battery pack 60 by the unlocking will be described. When the key unit is not inserted into the pressing force 24A or the operation is not performed, the contact portion 25 moves from the 2 nd position to the 1 st position by an urging force based on an urging member (not shown). In this case, the battery pack 60 is held by the battery holder 10 in a state where the support surface 25A forming the contact portion 25 can support the held portion 62 of the battery pack 60.
When the key unit is rotated in one direction, the pressing force 24A rotates, the 1 st cam 26A moves along the groove 28A, and the 1 st cam 26A presses the 2 nd cam 26B, whereby the contact portion 25 is displaced from the 1 st position to the 2 nd position. In this case, the battery pack 60 can be detached from the battery holder 10. Since the battery pack 60 is biased by a battery biasing device 80 (described later) so that the battery pack 60 comes out of the battery housing space DT1, the battery pack 60 rotates (described later), and the 1 st end portion 61 of the battery pack 60 comes out of the battery housing space DT1. When the battery pack 60 is rotated to the 2 nd holding position, the 2 nd protrusion 72 of the 1 st end portion 61 of the battery pack 60 engages with the 1 st protrusion 71 of the 1 st battery holder 12, and the rotation of the battery pack 60 is stopped. In this way, during removal of the battery pack 60, the battery pack 60 is temporarily held in the middle of the movement path when the battery pack 60 is removed.
The 2 nd battery holder 32 shown in fig. 9 includes a movable member 34 and a2 nd biasing member 48, the movable member 34 includes a2 nd supporting surface 34A which is in contact with the 2 nd end portion 65 of the battery pack 60 and is movable relative to the body frame A1 of the human-powered vehicle a, and the 2 nd biasing member 48 biases the movable member 34 toward the battery pack 60.

The battery pack 60 is detached from the battery holder 10, for example, through the following procedure. In the 1 st flow, the contact portion 25 of the lock mechanism 24 is moved in a direction away from the held portion 62 of the battery pack 60 by key operation. In this way, in a state where the 2 nd end portion 65 of the battery pack 60 is supported by the 1 st engaging portion 40 of the 2 nd cell holder 32, the 1 st end portion 61 of the battery pack 60 moves downward due to its own weight and the biasing force of the biasing member 84, and the battery pack 60 rotates about the 1 st engaging portion 40 as a rotation fulcrum. Since the battery pack 60 is biased to be pushed out from the battery housing space DT1 by the biasing member 84, the 1 st end portion 61 of the battery pack 60 is pushed out from the battery housing space DT1 when the lock is released by the key operation. When the battery pack 60 is rotated to a predetermined angle, the 2 nd protrusion 72 of the 1 st end portion 61 hits the 1 st protrusion 71 of the 1 st battery holder 12, and the rotation is stopped. In the 2 nd flow, the pressing portion 76 of the battery pack 60 is pressed while supporting the battery pack 60 on one side, and the engagement between the 2 nd protrusion 72 of the 1 st end portion 61 of the battery pack 60 and the 1 st protrusion 71 of the 1 st battery holder 12 is released. Thus, the battery pack 60 can be smoothly and safely taken out from the battery housing space DT1 without being dropped.
