[0022]
As shown in FIG. 10, in the state before the safety plug 30 is attached to the lock mechanism 40, the operation prohibiting permission link 80 has a holding shaft with a slight elastic deformation of the curved portion 85 at the end of the lock arm 86. 44, the rotation prohibition of the operation prohibition permission link 80 around the rotation shaft 45 is suppressed. The end portion of the stop arm 88 of the operation prohibiting permission link 80 is in contact with the stop portion 68 of the end portion of the arm 67 formed on the cam 66 of the lock link 60. Rotation around 47 is prohibited. At this time, the lower head 74 of the heads 72 and 74 of the lock rod 70 of the lock link 60 is stopped in a state of protruding from the lock hole 52 of the lower member 50. Therefore, if the lock mechanism 40 is attached to the lid 14 of the case 10, the lid 14 is closed and locked by the head 74 of the lock rod 70 as shown in FIG. 14.
[0023]
When the safety plug 30 is inserted into the mounting portion 42 of the lock mechanism 40, the operation shaft 38 formed on the handle 36 of the safety plug 30 is connected to the operation arm 86 of the operation prohibiting permission link 80 as shown in FIG. Abut. Further, when the safety plug 30 is inserted into the mounting portion 42, the pressing force of the operating arm 86 by the operating shaft 38 causes a slight elastic deformation in the curved portion 85 at the end of the lock arm 86, and the fitting with the holding shaft 44. The state is released, and the operation prohibiting permission link 80 is rotated counterclockwise as shown in FIG. At this time, the contact state of the stop arm 88 of the operation prohibiting permission link 80 with the stop portion 68 of the arm 67 is also released along with the rotation drive. For this reason, the lock link 60 is released from the rotation prohibition state about the rotation shaft 47 by the operation prohibition permission link 80, but the operation shaft 38 of the safety plug 30 is positioned in the operation opening 69. As a result, the operating shaft 38 comes into contact with the arm 67 and its rotational drive is suppressed.
[0024]
When the handle 36 of the safety plug 30 is tilted to the right side in FIG. 12 from this state, the operation shaft 38 contacts the cam 66 side of the operation opening 69 of the lock link 60 and moves in an arc. For this reason, as shown in FIG. 13, the lock link 60 rotates in the direction of the arrow about the rotation shaft 47 as the operation shaft 38 moves in an arc, and the head 74 of the lock rod 70 moves the lower member 50. Is housed inside the lower member 50 through the lock hole 52. As a result, if the lock mechanism 40 is attached to the lid 14 of the case 10, as shown in FIG. 15, the lid 14 by the head 74 of the lock rod 70 is released from the closed lock, and the lock mechanism 40 is 16 can be removed from the lid 14. On the other hand, even if the safety plug 30 tries to be removed from the lock mechanism 40 in a state where the handle 36 is tilted, the operation shaft 38 comes into contact with the upper portion 43a of the operation hole 43 of the housing 41 and suppresses it. Therefore, the safety plug 30 cannot be removed from the lock mechanism 40 when the lock mechanism 40 is unlocked.
[0025]
The operation for releasing the closing lock of the lid 14 by the lock mechanism 40 has been described together with the mechanism. The closing lock operation of the lid 14 by the lock mechanism 40 is the reverse procedure of the closing lock release operation. That is, from the unlocked state of FIG. 13, the handle 36 of the safety plug 30 is raised to release the prohibition of detachment of the safety plug 30 from the lock mechanism 40 and to lock the safety mechanism 30 as shown in FIG. This is an operation of pulling out from the lock mechanism 40.
[0026]
According to the interlock device 20 for the secondary battery of the embodiment described above, when the unlocking operation of the lock mechanism 40 is performed, the safety plug 30 is detached from the safety plug mounting portion 13 and the power supply to the secondary battery is cut off. Since it is necessary to attach to the lock mechanism 40 after that, it is possible to ensure higher safety for the operator. In addition, the lock mechanism 40 prohibits the safety plug 30 from being detached when the safety plug 30 is operated to release the closed lock of the lid 14, and locks the safety plug 30 when the safety plug 30 is locked. Since disengagement from the mechanism 40 is permitted, it is possible to prevent the safety plug 30 from being attached to the safety plug mounting portion 13 by removing the safety plug 30 from the lock mechanism 40 in the unlocked state. Of course, the lid 12 can be closed and locked by the safety plug 30.
[0027]

However, the bolt that attaches and fixes the lid 14 may be closed and locked by the lock mechanism. FIGS. 17 to 19 are explanatory views showing the unlocking operation by the safety plug 30 of the locking mechanism 40B for closing and locking the bolt for attaching and fixing the lid 14, and FIG. 20 shows the safety by disassembling the modified locking mechanism 40B. FIG. 21 is an exploded perspective view showing together with the plug 30, and FIG. 21 is an explanatory view showing the inside of the lock mechanism 40 </ b> B of the modified example together with the safety plug 30. As shown in FIGS. 20 and 21, the lock mechanism 40B according to the modified example has a point where an opening 42B is formed in the casing 41B and a through hole 54B of a mounting bolt 52B in the lower member 50B. Except for the point and the structure of the lock link 60B, the configuration is the same as the lock mechanism 40 of the embodiment. Therefore, in the configuration of the lock mechanism 40B according to the modification, the same reference numerals are given to the same configurations as those of the lock mechanism 40 according to the embodiment, and the description thereof is omitted.
[0028]
FIG. 22 is a perspective view showing an appearance of the lock link 60B. As shown in FIGS. 21 and 22, the lock link 60B includes a cam 66 and an arm 67 similar to the lock link 60 of the embodiment on the link main body 62B. An arcuate lid portion 64B is attached to the link body 62B.
[0029]
FIG. 23 to FIG. 26 are explanatory diagrams for explaining the unlocking operation of the lock mechanism 40B of the modified example using the safety plug 30. FIG. As shown in the figure, the lock mechanism 40B according to the modified example operates in the same manner as the operation prohibition permission link 80 and the lock link 60 of the lock mechanism 40 according to the embodiment by attaching the safety plug 30 and operating the handle 36 to lock. The lid portion 64B of the link 60B is rotated to enable the operation of the bolt 52B through the opening portion 42B of the housing 41B, and the operation to the bolt 52B is performed through the opening portion 42B of the housing 41B by the reverse procedure. Close and lock.
[0030]
The interlock device for a secondary battery provided with the lock mechanism 40B of the modified example described above can achieve the same effects as the interlock device 20 for the secondary battery of the embodiment.
[0031]
In the lock mechanism 40 of the embodiment and the lock mechanism 40B of the modified example, the same operation prohibiting permission link 80 is used. However, when the safety plug 30 is not attached, the rotation of the locking links 60 and 60B is prohibited, As long as the safety link 30 is attached and the lock link 60, 60B associated with the operation of the handle 36 is allowed to rotate, any shape of the operation prohibiting permission link may be used. FIG. 27 is an exploded perspective view of the modified lock mechanism 40C including the operation prohibition permission link 80C having a different shape and is shown together with the safety plug 30. FIG. 28 is an exploded perspective view of the inside of the modified lock mechanism 40C. FIG. 29 is a perspective view showing an appearance of the operation prohibiting permission link 80C. As shown in FIGS. 27 to 29, the lock mechanism 40C of the modification has the same configuration as the lock mechanism 40B of the modification except that the shape of the operation prohibition permission link 80C is different. Therefore, in the configuration of the lock mechanism 40B according to the modification, the same reference numerals are given to the same configurations as those of the lock mechanism 40 according to the embodiment, and the description thereof is omitted.
[0032]
As shown in the drawing, the operation prohibiting permission link 80C is attached to two sides of the lock arm 84C and the stop arm 86C extending at an angle of about 180 degrees around the rotation hole 82C, and to the side of the rotation hole 82C.

In the figure, the locking arm 86C abuts against the cam 66 of the locking link 60B, thereby prohibiting the rotation of the locking link 60B. The lock arm 84 </ b> C is positioned such that its end portion floats on the bottom of the mounting portion 42. When the safety plug 30 is mounted on the modified lock mechanism 40C, as shown in FIGS. 31 and 32, the lower end of the housing 32 of the safety plug 30 is pushed against the urging force of the spring portion 88C against the lock arm 84C. As a result, the operation prohibition permission link 80C rotates in the counterclockwise direction, and the prohibition state of the rotation drive of the lock link 60B due to the contact of the stop arm 86C with the cam 66 is released. However, since the operation shaft 38 of the safety plug 30 is positioned at the operation opening 69, the operation shaft 38 comes into contact with the arm 67 and the rotational drive thereof is suppressed.
[0034]
Since the operation of the lock mechanism 40C when the handle 36 of the safety plug 30 is tilted from this state is the same as that of the lock mechanism 40 of the embodiment and the modified example 40B, the description thereof is omitted to avoid redundant description.
