< effect of screw-type lockable mechanism >
The screw-type lockable mechanism 22 of said structure is when practical application; Locking pedestal 31 batteries 2 (battery frame 2a) that are installed in as noted above upward are arranged on battery 2 sides; Locking plate 27 is installed on the car body floor 5 and is arranged on the car body side; Battery 2 can accommodated in the battery container space of the downwardly facing opening of car body floor 5 downsides with freely dismantling and during locking, screw-type lockable mechanism 22 through and locking plate 27 between mutual action, and shown in following, play this latch functions.
At first, based on Figure 13~15, the locking effect when battery is installed is described.
When the installation of battery 2; Through bolt 32 lax direction shown in the arrow in Figure 13 (a) is rotated; Make black nut 33 shown in the detailed record of back; Utilize black nut interlock turning unit 34 and interlock rotation, and utilize hill holder 31b and stop at the lax direction restriction site (non-lock position) shown in Fig. 9 and Figure 13 (a).
Here; If battery 2 is risen in the battery container space of downwardly facing opening of car body floor 5 lower surfaces; Then black nut 33 utilizes the above-mentioned mutual action between conical surface 33a, 33b and the locking plate rectangular opening 27a, thereby feels relieved with respect to locking plate rectangular opening 27a, and passes the locking plate rectangular opening 27a shown in Fig. 9 and Figure 13 (a); Simultaneously; The central circular lug boss 31a of locking pedestal 31 is absorbed among the locking plate circular port 27b, makes black nut 33 be positioned at the battery container space, and locking pedestal 31 is connected to the outside of locking plate 27 and exposes on the lower surface.
Under this state; If utilize nut driving machine etc. to make bolt 32 fastening direction rotation shown in the arrow in Figure 13 (b); Then force interlock turning unit 34,, make black nut 33 interlock rotations via smooth camming surface 34c and conical surface 33a with the black nut of bolt 32 rotations; Utilize this black nut 33 to contact, make this black nut 33 be positioned at the fastening direction restriction site (lock position) shown in Figure 10, Figure 13 (b) and Figure 14 (a) with collision between the hill holder 31c.
Black nut 33 utilizes black nut to force the rotation that links of interlock turning unit 34, but can not cross this fastening direction restriction site (lock position), but shown in Figure 10, Figure 13 (b) and Figure 14 (a), stops at this position of rotation.
In addition, black nut is forced interlock turning unit 34, begins from the state of Figure 15 (a); Shown in this figure (b), antagonistic spring 35 and make smooth camming surface 34c cross black nut long side conical surface 33a, this crosses simultaneous; Spring 35 is compressed; And the direction to away from black nut 33 moves, and can rotate relatively with respect to black nut 33, thereby can discharge black nut interlock rotational force.
Therefore, can not hinder bolt 32 owing to the existence of black nut pressure interlock turning unit 34 further to fastening direction rotation.
If make bolt 32 further to fastening direction rotation; Then black nut 33 is shown in Figure 14 (b); Keep fastening direction restriction site (lock position) and be screwed into to the direction of arrow of this figure; Force interlock turning unit 34 (34b of foot) to separate with the black nut of the lower position shown in this figure, simultaneously to moving with locking pedestal 31 approaching directions.
Thus, at black nut 33 and locking pedestal 31 clamping locking plate 27 between the two, can and remain on the position that is contained in the battery container space battery 2 lockings.
Below, based on Figure 16~18, the non-locking effect when the battery dismounting is described.

But black nut 33 utilizes black nut to force the rotation that links of interlock turning unit 34, but can not cross this lax direction restriction site (non-lock position), but shown in Figure 17 (b), stops at this position of rotation.
In addition, black nut is forced interlock turning unit 34, begins from the state of Figure 18 (b); Shown in this figure (a), antagonistic spring 35 and make smooth camming surface 34c cross black nut long side conical surface 33a, simultaneously; Be accompanied by this and cross and spring 35 is compressed, and move, simultaneously to direction away from black nut 33; Can rotate relatively with respect to black nut 33, thereby can discharge black nut interlock rotational force.
Therefore, can not hinder bolt 32 owing to the existence of black nut pressure interlock turning unit 34 further to lax direction rotation.
If make bolt 32 further to lax direction rotation; Then black nut 33 keeps lax direction restriction site (non-lock position) and carries out relaxation stroke to the direction of arrow of this figure shown in Figure 17 (b); Compression spring 35; Make black nut force interlock turning unit 34 (34b of foot) to produce displacement simultaneously to same direction, and, move to direction away from locking pedestal 31.
Thus; The clamping force (locking) that releasing applies through black nut 33 and 31 pairs of locking plates 27 of locking pedestal; Can make black nut 33 pass the rectangular opening 27a of locking plate 27; Central circular lug boss 31a with locking pedestal 31 extracts from the circular port 27b of locking plate 27 simultaneously, simultaneously battery 2 is dismantled in the battery container space.
