The specific embodiment
Below in conjunction with accompanying drawing the preferred embodiment of the present invention is described.
The power battery box of electric vehicle latching device is shown in Fig. 1-6, and it comprises locking plate 1, lock pin 2, housing 3, retracing spring 4, actuating device 5, safety pin 6, preloading spring 8 etc.
When power battery box 11 is installed, safety pin 6 is in the state of pulling up, locking plate 1 is in the unlocked position of avoiding lockhole, lock pin 2 inserted lockhole and compresses preloading spring 8 by the preloading spring seat 9 in the compression preloading spring chamber 7 along with packing into of power battery box 11, until surpassing locking plate 1, the locked groove of lock pin 2 reaches default latched position, actuating device 5 is stirred in the locked groove that locking plate 1 snaps in lock pin 2, with 2 lockings of lock pin, has just finished the locking process of power battery box 11 this moment.
After power battery box 11 lockings, safety pin 6 falls, and prevents that locking plate 1 breaks away from locked position in the electronlmobil operational process, and simultaneously, preloading spring 8 also serves the same role.If lock pin 2 is installed, after power battery box 11 lockings, can rely on the self gravitation of power battery box 11 and preloading spring 8 that lock pin 2 is pressed on the locking plate 1 from bottom to top; If lock pin 2 levels are installed, then predetermincd tension provides by preloading spring 8 entirely.
Shown in Fig. 3-6, lock pin 2 comprises major part part and locked groove, and major part partly is preferably with tapering in this programme, plays like this directional tagging and makes things convenient for lock pin 2 to insert lockhole, locked groove is preferably and adopts eel-like figure partly to form, thereby lock pin 2 forms the shape of " the large waist of head is thin ".Locking plate 1 is provided with small one and large one two circular holes that run through, be communicated with the slotted hole of small sircle hole equal diameters with width between two circular holes, thereby form the through hole of " Pear-Shaped ", through hole one end diameter is the circular hole that is slightly larger than lock pin major part part, it is big hole, other end diameter is to be slightly larger than lock pin eel-like figure part still less than major part circular hole partly, i.e. small sircle hole.Actuating device 5 can provide straight-line mechanism for rack-and-gear, feed screw nut, ratchet, cam, spring, connecting rod, fork etc., and power resources can be motor, cylinder, hydraulic actuating cylinder, electromagnet.
Shown in Fig. 3 and 5, in locking at first, locking plate 1 driven device 5 is shifted left end onto, big hole aligns with lockhole on the housing 3 on the locking plate 1, lockhole on the housing 3 is identical or bigger with big hole diameter on the locking plate 1, and this moment, lock pin 2 major parts part can be passed locking plate 1 smoothly, when the upper surface of lock pin 2 eel-like figures part is higher than locking plate 1 upper surface, and lock pin 2 eel-like figure part lower surfaces move on lock pin 2 stops when being lower than locking plate 1 lower surface.At this moment, actuating device 5 is shifted locking plate 1 onto right-hand member, allows lock pin 2 eel-like figures partly snap in locking plate 1 small sircle hole, and last safe pin 6 falls and blocks the direction that locking plate 1 moves to left, and has so just finished the locking process, such as Fig. 4 and shown in Figure 6.Releasing process is the backward of locking process.
For cooperating automatically fast exchange device quick-replaceable electrokinetic cell, this device also configured preloading spring position transduser, locking plate position transduser and or the power battery box position transduser, sensor is preferably the locking plate release and locks onto level sensor 14, battery box to level sensor 15 to level sensor 12, pretension to level sensor 13, locking plate in this programme.
Illustrated power battery box of electric vehicle latching device scheme two such as Fig. 7-8, below only described the part different with scheme one, same section repeats no more.Lock pin 2 comprises major part part and locked groove, and to be preferably the cross section be leg-of-mutton groove to locked groove in this programme, can be leg-of-mutton annular groove, i.e. triangle annular groove.One section of locking plate 1 is the projection that can snap in locked groove, and locking plate 1 can rotate around a fulcrum, along with the rotation of locking plate 1, in the protruding triangle annular groove that just in time can insert on the lock pin 2.
Shown in Fig. 7-8, in when beginning locking, cam is shifted the projection of locking plate 1 outside the lockhole that lock pin 2 will insert onto, and like this, lock pin 2 can insert lockhole smoothly.When the triangle annular groove of lock pin 2 reached the position that projection inserts, cam rotated, and projection is inserted triangle annular groove on the lock pin 2, and last safety pin 6 is released, and finishes locking process.Releasing process is the backward of locking process.
The power battery box lockout mechanism that this programme provides, can integrated guiding and pretension function, and easily realize sealing, the cost of being convenient to improve the reliability of locking system and can effectively reducing the power battery box catch gear guarantees quick loading and unloading and the failure-free work in car of power battery box.
Shown in Fig. 9-10, the present invention also provides a kind of electronlmobil that described power battery box of electric vehicle latching device 16 is installed, and power battery box of electric vehicle latching device 16 is arranged in the periphery of power battery box 11.Fig. 9 is the distribution schematic diagram of relevant portion on power battery box 11 of described latching device 16, also be distributed with simultaneously the other part of described power battery box latching device 16 on the relevant position on the automobile, according to the size of power battery box 11 and quantity and the position of weight change latching device.Preferably, this electronlmobil is provided with four described power battery box of electric vehicle latching devices 16, four described power battery box of electric vehicle latching devices 16 are distributed on the mounting rail 17 on battery box installing space 18 both sides, and battery box installing space 18 is arranged on the electric automobile chassis 19.
