For achieving the above object, the technical solution adopted in the utility model is: a kind of hermetically sealed electrokinetic cell PACK case of controllable pressure, comprise the upper shell and lower house that can form a confined space, described upper shell and lower house surrounding all have bending part, upper shell and lower house carry out clamping connection by bending part, between access section, have rubber seal; Described lower house is also provided with waterproof and breathable relief valve.
Improve further as the utility model, described bending part comprises the coupling Z-shaped bending part of clamping first and the second Z-shaped bending part mutually; Described rubber seal is arranged on after between the second Z-shaped bending part interlude and first Z-shaped bending part one side section and is locked by securing member and waterproof Self-Clinching Standoffs; Described second Z-shaped bending part on one side section is affixed on the first Z-shaped bending part interlude inwall, extends to the first Z-shaped bending part another side section direction; The second rubber seal is provided with between section and the first Z-shaped bending part another side section on one side at described second Z-shaped bending part.
Improve further as the utility model, described rubber seal has U-lag.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:
The hermetically sealed electrokinetic cell PACK case of the utility model controllable pressure, upper shell and lower house surrounding realize the encapsulation process of multilayer by bending part and rubber seal, by installing waterproof and breathable relief valve on lower house while improving the reliability of battery PACK box body sealing structure, electrokinetic cell PACK body inside and outside air pressure is balanced, prevent because electrokinetic cell PACK body inside and outside air pressure is poor, the box deformation caused, or other destroys situation.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solutions of the utility model are described further:
Accompanying drawing 1 is the structural representation of the hermetically sealed electrokinetic cell PACK case of controllable pressure of the present utility model;
Accompanying drawing 2 is the A portion partial enlargement structural representation of the hermetically sealed electrokinetic cell PACK case of controllable pressure of the present utility model.
Embodiment
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
The hermetically sealed electrokinetic cell PACK case of the described in the utility model a kind of controllable pressure as shown in accompanying drawing 1,2, comprise the upper shell 1 and lower house 2 that can form a confined space, described upper shell 1 and lower house 2 surrounding all have bending part, upper shell 1 and lower house 2 carry out clamping connection by bending part, have rubber seal 3 between access section; Lower house 2 is also provided with waterproof and breathable relief valve 4.
Upper shell 1 and lower house 2 carry out clamping connection by bending part, have rubber seal 3 between access section, achieve multilayer flashing structure, then by the combination with waterproof and breathable relief valve 4, effectively can lower the frequency that box sealing damage inactivation occurs.
Bending part comprises the Z-shaped bending part of coupling clamping first 5 and the second Z-shaped bending part 6 mutually; Rubber seal 3 is arranged on after between the second Z-shaped bending part interlude 61 and first Z-shaped bending part one side section 51 and is locked by securing member 7 and waterproof self-clinching nut 8 post, forms ground floor waterproofing protection to Battery case inside; Second Z-shaped bending part on one side section 62 is affixed on the first Z-shaped bending part interlude 52 inwall, extends to the first Z-shaped bending part another side section 53 direction; The second rubber seal 9 is provided with between section 62 and the first Z-shaped bending part another side section 53 on one side at the second Z-shaped bending part; second rubber seal 9 and the second Z-shaped bending part on battery PACK casing lower house 1 on one side section 62 coordinate, and form second layer waterproofing protection to battery PACK box house.
Rubber seal 3 has U-lag 31.Stop battery PACK casing lower house 2, battery PACK casing upper shell 1 encapsulation process bad and a small amount of liquid of infiltration, a small amount of liquid infiltrated from securing member 7 threaded portion also can be stoped simultaneously to enter PACK box house.
On battery PACK casing lower house 2, also waterproof and breathable relief valve 4 is installed, by selecting the specification of suitable waterproof and breathable relief valve 4, can air pressure effectively inside and outside balancing battery PACK casing, prevent because the change of battery PACK box house pressure, caused seal failure.
On battery PACK casing lower house 2, for installing the securing member that other runs through casing annex, adopt waterproof Self-Clinching Standoffs 8, concrete specification is selected as required, can effectively prevent from seeping water from securing member 7 threaded portion to electrokinetic cell PACK box house.
