Embodiment
Below with reference to the drawings and specific embodiments the utility model is described in further details.
As depicted in figs. 1 and 2; the utility model is used for the specific embodiment of the safe battery case of hybrid vehicle; it comprises and is used for the battery case housing 2 of equipped with battery group 1; high-tension battery group 1 is installed in the bottom in the battery case housing 2; battery case housing 2 comprises inner housing 21 and shell body 22; inner housing 21 and shell body 22 are nonmetallic materials, have certain resistance to compression, shock proof ability, can effectively protect battery case.Referring to shown in Figure 3, between inner housing 21 and shell body 22, be provided with intermediate layer 4, the metal level 42 that this intermediate layer 4 comprises interlayer grid 41 and is installed in interlayer grid 41 both sides, interlayer grid 41 can be the lower plastic material of intensity, also can offer several ventilation holes on interlayer grid 41.Metal level 42 is the thin-sheet metal sheet, and as scale copper, two metal levels 42 are embedded at the both sides of interlayer grid 41 respectively, by interlayer grid 41 it is separated, and two metal levels 42 are arranged in the disjunction motor control loop.Referring to shown in Figure 4, be equiped with high-tension electricity break-up device 3 in the battery case housing 2, high-tension electricity break-up device 3 comprises disjunction case 31 and is installed in drive motors 32 in the disjunction case 31 and the section breaker group 35 that is used for controlling battery pack 1, drive motors 32 links to each other with section breaker group 35 by transmission mechanism, transmission mechanism comprises crank 33 and connecting rod 34 in the present embodiment, transmission mechanism disjunction case 31 is installed on the madial wall of battery case housing 2, the output shaft of drive motors 32 links to each other with crank 33, connecting rod 34 1 ends are installed on the crank 33, are equiped with section breaker group 35 on the other end.Referring to shown in Figure 6, section breaker group 35 is made up of several section breakers 351, the number of section breaker 351 is to determine according to the voltage of battery pack 1, the voltage that guarantees the battery pack 1 of its each section breaker 351 controls is less than or equal to safe voltage, when section breaker 351 disconnected, every group of voltage in its battery pack of controlling 1 will be less than or equal to safe voltage.In the present embodiment, the shift knob 36 of drive motors 32 is installed on the madial wall of disjunction case 31, and crank 33 is provided with the projection 37 that cooperates with shift knob 36.In the present embodiment, battery case housing 2 offers ventilation hole 5, is used for making battery pack 1 heat radiation.In the disjunction motor control loop, hand switch 38 can be set further, can be used for the keying of manual controlling and driving motor 32.
