Brief description of the drawings
Fig. 1 is a kind of structural representation of embodiment of the battery case retaining mechanism of the present invention;
Fig. 2 is Fig. 1 sectional view.
Embodiment
The embodiment of the battery case retaining mechanism of the present invention:As shown in Figure 1 and Figure 2, including tapered end 1 and axially be inserted into
Lock tube 2 in tapered end endoporus, for guiding movement before and after tapered end 1, the left and right sides of tapered end 1 is driven by link gear respectively to be connected
It is connected to the dead bolt acted along battery case left and right directions(Do not shown in the part figure), the rear end of lock tube 2 is used to be installed in battery case
On front panel, the effect of tapered end 1 is, by movable on lock tube 2, two dead bolts of drive move and with moving accordingly
Lockhole grafting on power storehouse coordinates to realize the locking of battery case or unblock.Two are provided between lock tube 2 and tapered end 1 along lock tube
Circumferential uniform, for realizing tapered end locking or unblock push type self-locking unit, should include axially directed activity from lock unit
The control shaft 3 inserted on tapered end front end face, control shaft 3 are pre-small post-large multi-diameter shaft, and tapered end 1 is stretched out in its front end, in tapered end 1
There is varus, spacing turning over the spacing cooperation of step surface of control shaft at the opening's edge in the axially directed hole inserted for control shaft 3
Edge, by it is spacing turn edge with axially directed hole bottom hole face realize control shaft 3 it is movable during it is spacing, in the present embodiment,
When control shaft step surface with it is spacing turn edge apical grafting when, control shaft 3 be in locking position, after control shaft move certain distance after, control
Axle 3 is in solution lock-bit;Tapered end sidewall sections between control shaft 3 and lock tube 2 offer radially-directed hole, in radially-directed hole
Guiding movement is fitted with stop-motion body, at the same time, on the outer peripheral face of lock tube 2 has the locking for supplying stop-motion body corresponding end to be caught in recessed
Portion, locking recess is the corresponding end interference fit of the through hole through lock tube side wall, the through hole and stop-motion body, so in locking position
When, stop-motion body top is mounted in the locking that tapered end 1 can be achieved between the enlarged diameter section of control shaft 1 and lock tube 2;In the outer peripheral face of control shaft 3
It is provided with the solution locked groove 6 for moving to after control shaft 3 and entering during solution lock-bit for stop-motion body corresponding end, i.e., when solving lock-bit, locking
Recess conciliates locked groove 6 diametrically, is pulled along tapered end 1, the radial compression stop-motion body of lock tube 2 makes its corresponding end enter unblock
The unblock of tapered end can be achieved in groove 6, accordingly, when control shaft 3 moves from solution lock-bit to locking position, the radial compression of control shaft 3
Stop-motion body makes its corresponding end be caught in the locking again that tapered end 1 can be achieved in locking recess again;In order to prevent control shaft 3 easy
After move and cause locking not firm, the Flexible Reset for applying active force facing forward to control shaft is provided between control shaft 3 and tapered end 1
Part, make control shaft step surface top pressure on spacing turn edge by return springs, while control shaft 3 is by solution lock-bit to locking position
Migration power can be realized by return springs, and in the present embodiment, return springs are stage clip 5, and one end apical grafting of stage clip 5 is being controlled
On the rear end face of axle processed, other end apical grafting is on the spring base 7 that axially directed hole hole is fixedly mounted on the bottom surface with.
As further optimization, stop-motion body uses the ball 4 that two radial directions are disposed proximate to, wherein, stop-motion body is caught in lock
The end of tight recess is the corresponding part of steel ball adjacent with lock tube, and the end for entering solution locked groove of stop-motion body is adjacent with control shaft
The corresponding part of steel ball,, can be with when stop-motion body is by radial compression using rolling effect of the steel ball 4 in radially-directed hole
Easily realize and move radially.
As further optimization, the solution locked groove 6 is along control shaft circumferentially extending, section is trapezoidal annular groove, unblock
The width of rebate of groove 6 is more than slot bottom width, using groove structure, can prevent from that the correspondence of stop-motion body occurs because control shaft rotates
End cannot be introduced into the phenomenon of solution locked groove.
When above-described embodiment is particularly applicable on battery case, the rear end of lock tube 2 is welded on battery case front panel, so locked
First 1 moving direction is consistent with the direction of battery case disengaging power bin.Under normal condition, control shaft 3 in the presence of stage clip 5,
Its step surface top pressure remains locking position on spacing turn edge, and the enlarged diameter section of control shaft 3 will be adjacent with lock tube 2
In steel ball part press-in locking recess, and then realize the locking of tapered end 1.The releasing process of tapered end 1 is as follows:Control shaft is pressed backward
3, the solution locked groove 6 in control shaft 3 is alignd with the radially-directed hole on tapered end, now control shaft 3 is in solution lock-bit, by manipulator
In insertion tapered end 1 and tapered end 1 is pulled out, two steel balls 4 are under the radial compression of lock tube 2 into the solution locked groove 6 in control shaft 3
Interior, such tapered end 1 unrestricted can move freely;The locking process of tapered end 1 is as follows:Tapered end 1 is pushed into make radially-directed hole
Alignd with solution locked groove, unclamp control shaft 3, control shaft 3 resets in the presence of stage clip 5, and now, two steel balls 4 are in control shaft 3
It is caught in again under radial compression in locking recess, that is, realizes locking.
In other embodiments, it can also be groove structure to lock recess, if section is arc or trapezoidal groove structure,
And it can also be the annular groove that section is arc to solve locked groove.
In other embodiments, stop-motion body can also use axial workpiece, and the left and right end portions structure of stop-motion body then basis
Lock recess conciliate locked groove structure design, if for example, locking recess or/and solution locked groove be that section is trapezoidal groove structure,
The corresponding end of stop-motion body is then to be adapted to the trapezium structure of grafting cooperation with trapezoidal annular groove, if solution locked groove or/and solution locked groove are to cut
Face is the groove structure of arc, and the corresponding end of stop-motion body is then the convex spherical structure that grafting cooperation is adapted to arc-shaped ring groove.
In other embodiments, return springs can also use extension spring, and extension spring is set in the smaller diameter end of control shaft
On, its one end with it is spacing turn edge be connected, the other end and control shaft step surface connect.
The embodiment of the electric automobile battery box of the present invention:Including casing and the locking machine being arranged on casing front panel
