The specific embodiment
The utility model is described preferred embodiment below in conjunction with accompanying drawing.
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, and locking plate 1 is in the unlocked position of avoiding lockhole, and lock pin 2 inserted lockhole and compresses preloading spring 8 through the preloading spring seat 9 in the compression preloading spring chamber 7 along with packing into of power battery box 11; Locked groove until lock pin 2 reaches preset latched position above locking plate 1; 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 accomplished 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 leans on preloading spring 8 to provide entirely.
Shown in Fig. 3-6; Lock pin 2 comprises major part partial sum locked groove, and major part partly is preferably and has tapering in this programme, plays directional tagging like this 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 big 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 width between two circular holes with the small sircle hole equal diameters; 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, i.e. 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 or the like, 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, lets 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 accomplished the locking process, like Fig. 4 and shown in Figure 6.Releasing process is the backward of locking process.
Change electrokinetic cell fast for cooperating automatically fast exchange device; This device also disposed 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 like Fig. 7-8, below only described and scheme one different portions that same section repeats no more.Lock pin 2 comprises major part partial sum 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 convexity that can snap in locked groove, and locking plate 1 can rotate around a fulcrum, along with the rotation of locking plate 1, and protruding just in time can the insertion in the triangle annular groove on the lock pin 2.
Shown in Fig. 7-8, when the locking beginning, cam is shifted the convexity of locking plate 1 outside 2 lockholes that will insert of lock pin onto, and like this, lock pin 2 can insert lockhole smoothly.When the triangle annular groove of lock pin 2 reached the position of protruding insertion, cam rotation was inserted the triangle annular groove on the lock pin 2 with convexity, and last safety pin 6 is released, and accomplishes 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 realize sealing easily, the cost of being convenient to improve the reliability of locking system and can effectively reducing the power battery box catch gear guarantees the quick loading and unloading of power battery box and reliable work in car.
Shown in Fig. 9-10, the utility model also provides a kind of electronlmobil that said 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 said latching device 16; Also be distributed with the other part of said power battery box latching device 16 simultaneously on the relevant position on the automobile, according to the size of power battery box 11 and the quantity and the position of weight change latching device.Preferably; This electronlmobil is provided with four said power battery box of electric vehicle latching devices 16; Four said 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.
