Embodiment
Below the specific embodiment of the present invention is described in further detail.
As shown in Figures 1 to 8, a kind of chassis type waterproof box body of the present invention, is mainly used in chassis type electromobile fast changeable, has the casing of paddle protection and water inlet emergency handling function. The innovative point of the present invention comprises: casing junction surface waterproof sealing structure, junctor waterproof sealing structure, junctor and casing junction surface sealed structure, junctor water logging power-off protection structure and casing water inlet series of cells are unwind operator guards. The present invention can ensure the personnel safety of electromobile passenger in the process of paddling; passing through smoothly lower than paddle the safely section of the degree of depth of electromobile; meet with after water logging is cast anchor at electromobile and carry out rapidly power current power-off protection, and emergency escape passage can be opened, for passenger withdraws rapidly offer.
Wherein, casing junction surface waterproof sealing structure comprises the casing 10 for placing battery group (not shown), case lid 12, joint strip 14, holding bolt 16 and fitting nut 18. Casing 10 upper surface open, case lid 12 is by this closure of openings. Joint strip 14 is compressed by casing 10 and case lid 12 by self structure, and is undertaken being pressed abd fixed in adhesive tape groove 17 by case lid 12 by holding bolt 16 and the fitting nut 18 being fixed on casing 10. Fitting nut 18 is arranged in pickup groove. Concrete structure is as shown in Figure 2.
Junctor waterproof sealing structure comprises junctor 19, and after junctor 19 comprises junctor fore shell 20, junctor, shell 22, mover electrode 24 and caulking gum 26 form. Mover electrode 24, by putting into caulking gum 26 in the mode of grooved faces, carries out press seal by shell after junctor fore shell 20 and junctor 22. After junctor fore shell 20 and junctor, junction surface between shell 22 is sealed by filling seal gum, and is compressed by holding bolt (not shown), as shown in Figure 4.
Junctor 19 and casing junction surface sealed structure comprise junctor chamber 28, Electrode connection post 30, set nut 32 and junctor erecting frame 34. Junctor chamber 28 is junctor installation position, concave space in the casing of independent closed, and junctor chamber 28 is except Electrode connection post 30 and the residing installation position of set nut 32, all isolated with casing 10 inside, avoids into water. Electrode connection post 30, by the anti-water-lute at set nut 32 place, avoids casing to intake. Junctor erecting frame 34 is for clamp connector. Junctor and casing junction surface sealed structure for avoiding the casing water inlet intake and cause due to junctor 19, as shown in Figure 5.
Junctor water logging power-off protection structure comprises first liquid sensor 36, sealing material 38, disconnect switch 40 and battery management system 42 and forms. First liquid sensor 36 is positioned over junctor 19 mid-way, with circular hole 46 UNICOM arranging mover electrode 44 on junctor 19, when mover electrode 44 meets with water logging, according to law of connected vessels, liquid will flow to first liquid sensor 36, and first liquid sensor 36 is by signal transmission to battery management system 42, and battery management system 42 is to disconnect switch 40 sending action signal, thus complete the disconnection process of battery and junctor mover electrode 44, as shown in Figure 7.
The casing water inlet series of cells operator guards that unwinds comprises drainage trough 48, second liquid sensor 50 and the 2nd disconnect switch 52 and forms. Drainage trough 48 is in junction surface (i.e. the edge of the opening) place of casing 10, and the junction surface one of around tank 10 is enclosed, as shown in Figure 6. If casing junction surface waterproof sealing structure occurs that inefficacy causes into water, then liquid preferentially flows into drainage trough 48, there is a place and the through hole 49 of the inner UNICOM of casing 10 in drainage trough, by fluid conduction to second liquid sensor 50, second liquid sensor 50 by signal transmission to battery management system 42, battery management system 42 is to the 2nd disconnect switch 52 sending action signal, thus completes series of cells 54 one-tenth Battery pack and unwind, as shown in Figure 8.
Above embodiment is only the present invention's a kind of enforcement mode wherein, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to patent scope of the present invention. , it is also possible to make some distortion and improvement, it should be appreciated that for the person of ordinary skill of the art, without departing from the inventive concept of the premise these all belong to protection scope of the present invention. Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
