Below, with reference to Figure 11,12, record and narrate black nut interlock rotating mechanism in detail, it is used at bolt 32 when fastening direction (in the present embodiment as right-hand thread) is rotated and when lax direction is rotated, make black nut 33 to the rotation that links forcibly of same direction, to fastening direction restriction site (lock position) shown in Figure 10,11 and lax direction restriction site (non-lock position) rotation shown in Figure 9.

Shown in Figure 11,12, by on the leading section periphery of the bolt 32 that is screwed into black nut 33, equally spaced form a plurality of axis direction groove 32a, thereby make the leading section of this bolt 32 become the non-circular profiles shape at circumferencial direction.

At the leading section of above-mentioned bolt 32, shown in Fig. 9,10, black nut is set and forces interlock turning unit 34 with chimeric ways of connecting.

This black nut is forced interlock turning unit 34, is made of plate-shaped member 34a and 2 34b of foot integrated with it.

Center at plate-shaped member 34a, run through the cooresponding non-circular hole 34d of above-mentioned leading section non-circular profiles shape that is provided with bolt 32, it is chimeric to be free to slide ground by the leading section that makes this non-circular hole 34d and bolt 32, thereby force interlock turning unit 34 to be set to black nut, can slide along axis direction with the leading section revotating card merging of bolt 32.

Black nut is forced interlock turning unit 34, utilize the spring 35 grade Flexible elements movable chimeric with the leading section of bolt 32, to black nut 33 pretensions, therefore, to force the spring perch 36 of the end institute butt of interlock turning unit 34 spring 35 far away apart from black nut, and engage with the leading section of bolt 32 and be provided with.

Utilizing spring 35 Flexible elements such as grade on the 34b of foot of the black nut pressure interlock turning unit 34 of black nut 33 pretensions, set smooth camming surface 34c respectively, mutual action between the above-mentioned long side conical surface 33a of its utilization and black nut 33, and produce following camming action.

Black nut is forced the inclination of the smooth camming surface 34c of interlock turning unit side, the feasible elastic force that utilizes spring 35, will be when bolt 32 rotation push to black nut long side conical surface 33a with the black nut of bolt 32 one rotation force the to link smooth camming surface 34c of turning unit 34, thereby can make black nut 33 interlock rotation, but this leaning angle is set at and can also realizes following effect.

Promptly, black nut forces the leaning angle of the smooth camming surface 34c of interlock turning unit side to be defined as, utilize hill holder 31b or 31c at black nut 33 and be suppressed in the counterparty after on the restriction site, black nut forces the smooth camming surface 34c of interlock turning unit 34 to cross black nut long side conical surface 33a, simultaneously, being accompanied by this crosses and compression spring 35 and move to the direction away from black nut 33, simultaneously, can rotate relatively with respect to black nut 33, thereby discharge black nut interlock rotational force.

Utilize spring 35 Flexible elements such as grade to the extreme limit of travel position that the black nut of black nut 33 pretensions is forced interlock turning unit 34, stipulate according to the length of the axis direction groove 32a on the leading section periphery that is arranged on bolt 32.

The 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, can accommodate in the battery container space of the downwardly facing opening of battery 2 below car body floor 5 and during locking with freely dismantling, screw-type lockable mechanism 22 by 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, by 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 27a feels relieved with respect to the locking plate rectangular opening, and pass 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, make black nut 33 be positioned at the battery container space, 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 with the black nut of bolt 32 rotations, via smooth camming surface 34c and conical surface 33a, make black nut 33 interlock 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, state from 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 move to direction, and can rotate relatively, thereby can discharge black nut interlock rotational force with respect to black nut 33 away from black nut 33.

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, the while is to moving with the approaching direction of locking pedestal 31.

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.

Remove locking so that battery 2 is taken out from the battery container space, under above-mentioned lockup state, utilize nut driving machine etc. that bolt 32 lax direction shown in the arrow to Figure 16 (a) in is rotated.

At first, because black nut 33 is shown in Figure 16 (a), at the locking identical with Figure 14 (b) with being screwed into the travel position place, force interlock turning unit 34 (34b of foot) to separate with the black nut of lower position, so force interlock turning unit 34 to the black nut of lax direction rotation with bolt 32, can can not cause any obstruction with respect to black nut 33 and to equidirectional relative rotation to the above-mentioned lax direction rotation of bolt 32.

The lax direction rotation of above-mentioned bolt 32 is moved black nut 33 lax direction shown in the arrow in Figure 16 (b) and Figure 17 (b), then, shown in Figure 18 (a), forces interlock turning unit 34 (34b of foot) to contact with the black nut of lower position.

But, under the contact condition shown in Figure 18 (a), black nut is forced interlock turning unit 34 (34b of foot) Shang Weiyue being screwed on the direction aft end face to black nut 33, can't produce black nut interlock rotational force, therefore, black nut force interlock turning unit 34 (34b of foot) and bolt 32 together with respect to black nut 33 to relative rotation of lax direction.

By above-mentioned relative rotation, black nut forces interlock turning unit 34 shown in Figure 18 (b), makes the smooth camming surface 34c of the 34b of foot be positioned at the relative position of rotation with black nut long side conical surface 33a.

At this moment, spring 35 is forced the direction of arrow pretension of interlock turning unit 34 to Figure 18 (b) with black nut, makes black nut force interlock turning unit 34 to become its smooth camming surface 34c and the relative travel position of black nut long side conical surface 33a.

Thus, shown in Figure 16 (b) and Figure 17 (a), in the same manner, the black nut 33 at fastening direction restriction site place and black nut are forced interlock turning unit 34 during with locking, by the mutual action of conical surface 33a and smooth camming surface 34c, and become the state that revotating card closes.

Under this state, if make bolt 32 further to lax direction rotation, then force interlock turning unit 34 with the black nut of bolt 32 rotations, via smooth camming surface 34c and conical surface 33a, make black nut 33 interlock rotations, this black nut 33 is forced to rotate to the lax direction restriction site (non-lock position) that contacts with hill holder 31b collision locate shown in Figure 17 (b).

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 stops at this position of rotation shown in Figure 17 (b).

In addition, black nut is forced interlock turning unit 34, 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 by 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.

But, connector unit 23 from 2 one group battery guidance unit 21 (with reference to Fig. 5) the two when far away and when only in these battery guidance units 23 is far away, because the accumulation of above-mentioned car body assembly error, produce the relative position skew and make between the battery side connector component 42 that constitutes connector unit 23 and the car body side-connector parts 41, can make the mutual fitting portion between battery side connector component 42 and the car body side-connector parts 41 produce eccentric.

Off-centre between above-mentioned battery side connector component 42 and the car body side-connector parts 41, can apply the lateral load on the direction of crossing chimeric direction to the mutual fitting portion of two connector components 41,42, the durability of connector unit 23 is reduced, and make the mutual fitting portion of connector component 41,42 produce the gap partly and become the reason that produces spark.

Therefore, in the present embodiment, the connector unit 23 that will be made of battery side connector component 42 and car body side-connector parts 41 as shown in Figure 5, be configured in and be arranged at battery guidance unit 21 the two approaching positions of the overall width direction both sides of battery 2, that is, with these battery guidance unit 21 equidistant midways location on.

The two is approaching for the connector unit 23 of above-mentioned configuration and battery guidance unit 21, and the influence that the position of car body side-connector parts 41 and battery side connector component 42 makes the accumulation by the car body assembly error cause minimizes, thus the high precision of obtaining.

Therefore, can almost eliminate the off-centre in the mutual fitting portion of above-mentioned connector component 41,42, can not cross lateral load on the direction of chimeric direction to the mutual fitting portion effect of two connector components 41,42, can eliminate following problems, promptly, make the durability reduction of connector unit 23 or make the mutual fitting portion of connector component 41,42 produce the gap partly, thereby produce spark.

In addition, if according to above-mentioned thinking, then connector unit 23 is configured in the middle of the overall width direction of car body floor 5.

In addition, in the middle of the overall width direction of car body floor 5, be set with the channel part of the convex shape of extending to the vehicle fore-and-aft direction, it is provided with passage component 6, with the intensity of guaranteeing car body floor 5 and the wire harness configuration that is used for car body side Denso system etc.

Therefore, in the present embodiment, connector unit 23 shown in Fig. 5,19,20, is configured in the passage component 6 (channel part) of convex shape, this passage component 6 extends along the vehicle fore-and-aft direction in the middle of the overall width direction of car body floor 5.

When this disposes, as shown in Figure 5, in the passage component 6 (channel part) at the position that can intersect at the front end face of the passage component 6 (channel part) of car body floor 5 and battery 2 (battery frame 2a), configuration connector unit 23.
