In numerous battery sizes, the overall dimensions of different batteries, rated voltage have tangible difference, so have multiple flashlight product on the market, and each product all uses the battery of specific model.These flashlight products generally only can use these independent batteries, and the battery of other models can't be installed, thus to battery select for use and the user causes many inconvenience.
The utility model content
The purpose of this utility model is to solve flashlight in the prior art can only use problem with a kind of overall dimensions battery, and then provides a kind of energy to be suitable for the battery powdered device of multiple size battery.
For this reason, the utility model provides a kind of energy to be suitable for the battery powdered device of multiple size battery, and it comprises: the stack shell with the accommodation hole that is suitable for installing many packet sizes battery; Be removably mounted on the bonnet of described stack shell bottom; Be fixed on the contact chip in the described bonnet; Be arranged in the described accommodation hole and be pressed against first cathode conductive film on the described contact chip by first spring; Be arranged in the described accommodation hole and be pressed against second cathode conductive film on the described contact chip and be installed in the cathode conductive film at described stack shell top by second spring.
Owing to adopt said structure, thereby make flashlight can be suitable for the battery of multiple different size, avoid the user to can not find the inconvenience that suitable batteries is brought, and strengthened the applicability of torch.
Description of drawings
Fig. 1 has showed the states that the less battery pack of many group appearance and sizes is installed for the utility model can be suitable for the three-dimensional exploded view of the battery powdered device of multiple size battery;
Fig. 2 has showed the compressive state figure of battery powdered device shown in Figure 1 bottom;
Fig. 3 is the cutaway view of structure shown in Figure 2, has showed the position relation between each member;
Fig. 4 be for the utility model can be suitable for the three-dimensional exploded view of the battery powdered device of multiple size battery, showed state that the bigger battery pack of many group appearance and sizes is installed,
The specific embodiment
After this preferred embodiment of the present utility model will be described with reference to the drawings.
With reference to figure 1-4, comprise stack shell 9, the bonnet 7 that is removably mounted on described stack shell 9 bottoms, the contact chip 6 that is fixed on described bonnet 7 inside, be arranged in the described accommodation hole and be pressed against first cathode conductive film 3 on the described contact chip 6, be arranged in the described accommodation hole and be pressed against second cathode conductive film 1 on the described contact chip 6 and be installed in the cathode conductive film 10 at described stack shell 9 tops by second spring 2 by first spring 4 with accommodation hole according to the battery powdered device 100 that can be suitable for multiple size battery of a preferred embodiment of the utility model.
Form external screw thread 92 on the bottom excircle of described stack shell 9, correspondingly, the inside of described bonnet 7 forms internal thread 72.Described bonnet 7 is removably mounted on the bottom of described stack shell 9 by external screw thread 92 and cooperating of internal thread 72.
The accommodation hole of described stack shell 9 vertically connects described stack shell 9 along the length direction of described stack shell 9.Described accommodation hole 9 alternately is connected to form such as three sections main circular arc inwalls 94 and the secondary circular arc inwall 96 of multistage by multistage.And the internal diameter of described main circular arc inwall 94 is greater than the internal diameter of described secondary circular arc inwall 96.The center of circle of the secondary circular arc inwall 96 of described multistage is positioned at the circumference inside of described main circular arc inwall 94.
Described first cathode conductive film 3 has and the corresponding shape of the inner wall shape of described accommodation hole 9.Promptly first cathode conductive film 3 is protruded arc sections 32 such as three sections and alternately is formed at three sections three sections recessed arc sections 34 protruding between the arc sections 32 by multistage and constitutes, and the center of described first cathode conductive film 3 has perforate 36.Protrude upward contact 38 on described each protrusion arc sections 32.
It is that 18650 or 17670 battery pack 8 is installed in the stack shell 9 such as the model among Fig. 1 that described accommodation hole 9 that alternately is connected to form such as the secondary circular arc inwall 96 of three sections main circular arc inwalls 94 and multistage by multistage and the first corresponding with it cathode conductive film 3 of shape are convenient to the battery pack that profile is less; In a single day and help to protect battery,, then can not produce relative rotary motion between the two, thereby can not cause the rotation of battery, and then can not cause damage battery because first cathode conductive film 3 is installed in the described accommodation hole 9; Simultaneously, the contact 38 on described first cathode conductive film 3 helps stably to support to be provided with battery pack 8 thereon.
The main circular arc inwall 94 of described accommodation hole 9 can be used for the bigger battery of installation dimension, such as the battery 8 ' that Fig. 4 showed.
The external diameter of described second spring 2 is less than the internal diameter of described first spring 4, and internal diameter less than the perforate 36 at described first cathode conductive film 3 centers, thereby can guarantee that second spring 2 passes the perforate 36 and first spring 4, an end that finally causes second spring 2 is against described contact chip 6, and the other end is then against described second cathode conductive film 1.When second spring 2 was in compressive state, described second cathode conductive film 1 was arranged in the middle of the perforate 36 of described first cathode conductive film 3.
Further preferably, described stack shell 9 can be provided with waterproof sealing gasket with the connecting portion of bonnet 7, thereby has strengthened integrally-built water resistance.
The beneficial effects of the utility model are: owing to adopt said structure, thereby so that flashlight can be suitable for the battery of multiple different size, such as 18650,17670,32650, the battery of three kind of model, avoid the user to can not find the inconvenience that suitable batteries is brought, and strengthened the applicability of torch.
