Referring to fig. 1 and 2, and referring to fig. 3, an energy storage device 100 of the present application includes a housing 10, a circuit board 20 and a cigar lighter 30. The housing 10 is provided with a connection hole 11 and a connection member 13 disposed around the connection hole 11. The circuit board 20 is provided with a mounting hole 21, and the connector 13 is clamped in the mounting hole 21 so that the circuit board 20 is mounted on the housing 10. The cigar lighter 30 is inserted into the circuit board 20 through the mounting hole 21 and partially extends into the connecting hole 11, and the cigar lighter 30 is mounted on the housing 10 and electrically connected with the circuit board 20.

In the energy storage power supply of the present application, the connecting piece 13 disposed on the housing 10 can partially extend into the mounting hole 21 of the circuit board 20 and be combined with the circuit board 20 to fix the relative position between the circuit board 20 and the housing 10, and the cigar lighter 30 can be directly mounted on the housing 10 through the connecting hole 11 and penetrate the circuit board 20. The shell 10, the circuit board 20 and the cigar lighter 30 can be directly mutually installed without adding other structures, the installation mode is simple and the structure is stable, and the cigar lighter 30 is not easy to fall off.

The energy storage device 100 is further described below with reference to the accompanying drawings.

Referring to fig. 2 and 3, and in conjunction with fig. 1, in some embodiments, the housing 10 is generally configured to mount or house various components within the energy storage device 100. In some embodiments, the housing 10 is provided with a receiving cavity, and a part of the structure of the energy storage device 100 can be disposed in the receiving cavity and connected to the housing 10, for example: the circuit board 20, the cigar lighter 30 and/or another part of the structure of the energy storage device 100 can be provided only in the receiving cavity without contacting the housing 10, such as a control chip or the like. The casing 10 can isolate the internal structure of the energy storage device 100 from the outside to protect the electrical components in the energy storage device 100, so as to prevent the structure in the energy storage device 100 from being corroded due to contact with water vapor or prevent the internal structure from being frosted, which affects the normal use of the energy storage device 100. The shape of the cross-section of the housing 10 includes, but is not limited to, a quadrilateral, pentagon, hexagon, octagon, etc. The material of the housing 10 includes, but is not limited to, insulating materials such as plastics, resins, or silicone, and conductive materials such as metals. The conductive portion of the housing 10 can be used to conduct electricity and participate in the formation of electrical circuits of the electrical components within the energy storage device 100. The insulating portion of the housing 10 can prevent electric leakage of electrical components in the energy storage device 100 and prevent electric shock to a user.

Specifically, in some embodiments, the housing 10 includes a first face 101 and a second face 103 that are opposite, the first face 101 of the housing 10 facing the receiving cavity of the energy storage device 100 and being the inside of the energy storage device 100, and the second face 103 of the housing 10 facing the outside of the energy storage device 100. The connection hole 11 provided in the case 10 can communicate the inside of the energy storage device 100 with the outside of the energy storage device 100. In some embodiments, the inner dimension of the connection hole 11 gradually decreases along the direction in which the first face 101 of the housing 10 is directed toward the second face 103 of the housing 10, at this time, the inner wall 111 of the connection hole 11 may form a slope inclined from the first face 101 of the housing 10 toward the second face 103 of the housing 10, and the slope may collide with the cigar lighter 30 so that the position between the cigar lighter 30 and the housing 10 is relatively fixed, and the cigar lighter 30 does not fall from the connection hole 11 along the direction in which the first face 101 of the housing 10 is directed toward the second face 103 of the housing 10. In other embodiments, the inner profile of the connection hole 11 increases gradually in a direction in which the first face 101 of the housing 10 is directed toward the second face 103 of the housing 10. In the case of installing the cigar lighter 30, one end of the cigar lighter 30 passes through the connecting hole 11 from the second surface 103 of the shell 10 and gradually extends into the energy storage device 100, since the inner dimension of the opening of the connecting hole 11 on the second surface 103 side of the shell 10 is larger, and the inner dimension of the opening of the connecting hole 11 on the first surface 101 of the shell 10 is smaller, the inner wall 111 of the connecting hole 11 can form an inclined plane inclined from the second surface 103 of the shell 10 to the first surface 101 of the shell 10, and a part of the structure of the cigar lighter 30 can be clamped in the connecting hole 11 and is abutted against the inclined plane, so that the cigar lighter 30 is connected with the shell 10 and the position between the cigar lighter 30 and the shell 10 is fixed.

Further, the connector 13 is configured to be able to connect to the circuit board 20 and position the cigar lighter 30. The material of the connector 13 includes, but is not limited to, an insulating material such as plastic or resin, and in the case where the connector 13 connects the cigar lighter 30 and the circuit board 20 at the same time, the connector 13 formed of the insulating material can prevent the cigar lighter 30 and the circuit board 20 from being electrically connected through the connector 13 and causing a short circuit. In some embodiments, the connecting piece 13 and the housing 10 are integrally formed, and the connecting piece 13 can be directly manufactured together when the housing 10 is produced by using a die, so that the processing is simpler. In other embodiments, the connector 13 is formed separately from the housing 10 and then mounted together. The connecting member 13 and the housing 10 may be attached together by a detachable connection such as a snap connection, a screw connection, or a bolt connection, or may be attached together by a non-detachable connection such as a glue connection, a hot-melt connection, or a welding connection. In some embodiments, the connector 13 is mounted to the first face 101 of the housing 10 and extends to a side proximate to the receiving cavity of the energy storage device 100. The circuit board 20 and the cigar lighter 30 are both disposed on the side of the first surface 101 of the housing 10 and located in the accommodating cavity of the energy storage device 100. In other embodiments, the circuit board 20 is disposed on the side of the first surface 101 of the housing 10 and is located in the accommodating cavity of the energy storage device 100, the connecting element 13 is mounted on the first surface 101 of the housing 10 and the second surface 103 of the housing 10, and a part of the cigar lighter 30 can pass through the connecting hole 11 from the first surface 101 of the housing 10 and protrude from the second surface 103 of the housing 10. The portion of the connector 13 on the first side 101 of the housing 10 is connected to the circuit board 20 to fix the position of the circuit board 20 to the portion of the connector 13 on the second side 103 of the housing 10 is connected to the cigar lighter 30 to fix the position of the cigar lighter 30.

Further, in some embodiments, the connecting member 13 includes a connecting portion 131 and an engaging portion 133 that are connected. The connecting portion 131 has a substantially plate-shaped structure with a curvature, one end of the connecting portion 131 is disposed on the first surface 101 of the housing 10 and located outside the connecting hole 11, and the other end of the connecting portion 131 is a free end facing the accommodating cavity. The engaging portion 133 is movably provided on the connecting portion 131, and is configured to be mounted on the connector 13 when the circuit board 20 is mounted thereon. The engaging portion 133 can pass through the mounting hole 21 and abut against the circuit board 20 to fix the circuit board 20 on the housing 10. The engaging portion 133 and the connecting portion 131 may be made of the same material or different materials. In some embodiments, the engaging portion 133 and the connecting portion 131 are integrally formed. In other embodiments, the engaging portion 133 and the connecting portion 131 are formed separately, and the engaging portion 133 and the connecting portion 131 may be mounted together by a detachable connection such as a snap connection, a screw connection, or a bolt connection, or may be mounted together by a non-detachable connection such as a glue connection, a hot-melt connection, or a welding connection.

Specifically, in some embodiments, the connection portion 131 includes a first side 1311 and a second side 1313 that are opposite, the first side 1311 of the connection portion 131 facing the connection aperture 11, and the second side 1313 of the connection portion 131 facing away from the connection aperture 11. The engagement portion 133 is provided on the second side 1313 of the connection portion 131 and can protrude from the second side 1313 of the connection portion 131 in a direction away from the connection hole 11, and an inner wall of the mounting hole 21 faces the second side 1313 of the connection portion 131. When the circuit board 20 is mounted on the connector 13, the circuit board 20 abuts against the engaging portion 133 and presses the engaging portion 133, and at this time, the engaging portion 133 moves in a direction approaching the connection hole 11. When the circuit board 20 continues to move in the direction approaching the housing 10 and passes through the position where the engaging portion 133 is located, the circuit board 20 is separated from the engaging portion 133, and at this time, the pressing force of the circuit board 20 to the engaging portion 133 disappears, and the engaging portion 133 resets and abuts against the side of the circuit board 20 away from the housing 10, so as to prevent the circuit board 20 from moving in the direction away from the housing 10.

More specifically, in some embodiments, the connector 13 further includes a limiting portion 135, and the limiting portion 135 is a generally cylindrical structure mounted to the connecting portion 131. The limiting portion 135 is disposed on the second side 1313 of the connecting portion 131 and protrudes from the second side 1313 of the connecting portion 131. The material of the limiting portion 135 and the connecting portion 131 may be the same or different. In some embodiments, the limiting portion 135 and the connecting portion 131 are integrally formed. In other embodiments, the limiting portion 135 and the connecting portion 131 are formed separately, and the limiting portion 135 and the connecting portion 131 may be mounted together by a detachable connection manner such as a snap connection, a threaded connection, or a bolt connection, or may be mounted together by a non-detachable connection manner such as a glue connection, a hot-melt connection, or a welding connection. In the case that the engaging portion 133 abuts against a side of the circuit board 20 away from the housing 10, the limiting portion 135 is configured to abut against a side of the circuit board 20 near the housing 10 to prevent the circuit board 20 from moving in a direction approaching the housing 10, and the circuit board 20 is fixed to the connecting member 13.

Still more particularly, in some embodiments, the connection member 13 may further include a plurality of connection members 13, each of which is disposed around the connection hole 11 and mounted to the housing 10. In some embodiments, the plurality of connectors 13 are all disposed on the same side of the housing 10, i.e., the plurality of connectors 13 are all located on the first side 101 of the housing 10 or the second side 103 of the housing 10. In other embodiments, the plurality of connectors 13 are provided on different sides of the housing 10, i.e., the plurality of connectors 13 can be provided on the first face 101 of the housing 10 and the second face 103 of the housing 10. The plurality of connection members 13 may be separated from each other or may be connected to each other.

Referring to fig. 1 and 3, in some embodiments, the circuit board 20 is electrically connected to the cigar lighter 30 (fig. 1) and supplies power to the cigar lighter 30, and the circuit board 20 can be fixedly connected to the housing 10 and the cigar lighter 30 respectively to prevent the cigar lighter 30 from falling off the housing 10 and to prevent the circuit board 20 from shaking relative to the housing 10, which affects the internal circuit connection of the energy storage device 100.

Specifically, referring to fig. 2, in some embodiments, the circuit board 20 includes a first side 201 and a second side 203 opposite to each other, the first side 201 of the circuit board 20 faces the accommodating cavity and is away from the housing 10, and the second side 203 of the circuit board 20 faces the first face 101 of the housing 10. In the case where the circuit board 20 is mounted to the connector 13, the connection portion 131 of the connector 13 passes through the mounting hole 21, and since the engagement portion 133 protrudes with respect to the second side 1313 of the connection portion 131, the circuit board 20 can press the engagement portion 133 and move or deflect the engagement portion 133 in a direction in which the second side 1313 of the connection portion 131 is directed toward the first side 1311 of the connection portion 131. When the circuit board 20 passes through the engaging portion 133 and is located between the engaging portion 133 and the limiting portion 135, the first side 201 of the circuit board 20 faces the engaging portion 133, and the second side 203 of the circuit board 20 faces the limiting portion 135. In some embodiments, the circuit board 20 abuts against the engaging portion 133 and the limiting portion 135, and the circuit board 20 can be stably mounted on the connecting member 13 and does not shake relative to the connecting member 13. In other embodiments, the circuit board 20 is separated from at least one of the engaging portion 133 and the limiting portion 135.

More specifically, in some embodiments, the mounting hole 21 is a structure formed on the circuit board 20 for avoiding the cigar lighter 30 and the connecting element 13. The cigar lighter 30 and the connecting portion 131 and the engaging portion 133 of the connecting element 13 can pass through the mounting hole 21, and the limiting portion 135 of the connecting element 13 does not pass through the mounting hole 21. Since the connection member 13 is disposed around the connection hole 11, and the cigar lighter 30 can pass through the connection hole 11, when the circuit board 20 is engaged with the connection member 13, the outer wall of the cigar lighter 30 is separated from the inner wall of the installation hole 21, and at this time, the cigar lighter 30 easily shakes in the installation hole 21. Thus, in some embodiments, the inner wall of the mounting hole 21 may also be provided with a positioning element 23, the positioning element 23 protruding into the mounting hole 21 and facing the cigar lighter 30, the positioning element 23 being able to define the position of the cigar lighter 30 within the mounting hole 21 in case the cigar lighter 30 protrudes into the mounting hole 21. In some embodiments, the positioning member 23 abuts the outer wall of the cigar lighter 30. In other embodiments, there is a gap between the positioning member 23 and the outer wall of the cigar lighter 30, and the gap between the positioning member 23 and the outer wall of the cigar lighter 30 is smaller than the gap between the inner wall of the mounting hole 21 and the outer wall of the cigar lighter 30.

Referring to fig. 2 and 4 in conjunction with fig. 3, in some embodiments, the cigar lighter 30 is a device capable of heating and igniting a cigarette. The energy storage battery within the energy storage device 100 is capable of electrically connecting with the cigar lighter 30 via the circuit board 20 and supplying power to the cigar lighter 30. The control chip within the energy storage device 100 can also be electrically connected to the cigar lighter 30 through the circuit board 20 and control the operation and stopping of the cigar lighter 30. One end of the cigar lighter 30 can be mounted in the housing 10 and disposed in the connection hole 11, and the other end of the cigar lighter 30 can pass through the circuit board 20 via the mounting hole 21.

Specifically, referring to fig. 5, in some embodiments, the cigar lighter 30 includes a first portion 31 and a second portion 33 that meet, wherein the outer dimension of the cross-section of the first portion 31 of the cigar lighter 30 is greater than the outer dimension of the cross-section of the second portion 33 of the cigar lighter 30. Thus, during installation of the cigar lighter 30 in the housing 10, the first portion 31 of the cigar lighter 30 can be connected to the housing 10 such that the cigar lighter 30 is disposed within the connection hole 11. The second portion 33 of the cigar lighter 30 can be disposed through the mounting hole 21. In some embodiments, the first portion 31 of the cigar lighter 30 is clamped on the first surface 101 of the housing 10, and at this time, the inner contour dimension of the connecting hole 11 gradually decreases along the direction of the first surface 101 of the housing 10 toward the second surface 103 of the housing 10, so that the first portion 31 of the cigar lighter 30 can collide with the inner wall 111 of the connecting hole 11, and both the first portion 31 of the cigar lighter 30 and the second portion 33 of the cigar lighter 30 can be disposed in the accommodating cavity. In other embodiments, the first portion 31 of the cigar lighter 30 is clamped on the second surface 103 of the housing 10, and at this time, the inner dimension of the connecting hole 11 gradually increases along the direction from the first surface 101 of the housing 10 to the second surface 103 of the housing 10, so that the first portion 31 of the cigar lighter 30 can collide with the second surface 103 of the housing 10, and the second portion 33 of the cigar lighter 30 can sequentially pass through the connecting hole 11 and the mounting hole 21 and be disposed in the accommodating cavity.

Referring to fig. 2 and 3, in some embodiments, the housing 10 may further include a conductive element 40, and the conductive element 40 is electrically conductive between the cigar lighter 30 and the circuit board 20. The conductive element 40 is disposed on the second surface 103 of the housing 10 and surrounds the connection hole 11, and the conductive element 40 is electrically connected to the cigar lighter 30 and the circuit board 20, so that the circuit board 20 can transmit electric energy and signals to the conductive element 40. The material of the conductive member 40 includes, but is not limited to, metal, conductive plastic, conductive rubber, or the like. Meanwhile, the conductive member 40 can be electrically insulated from the housing 10, so as to avoid the power leakage of the energy storage device 100 caused by electrification of the housing 10.

Specifically, in some embodiments, the conductive elements 40 include at least two, with at least two conductive elements 40 spaced apart to avoid shorting between the circuit board 20 and the cigar lighter 30. In some embodiments, the connector 13 and the conductive element 40 each comprise a plurality, each conductive element 40 being located between two connectors 13, and each conductive element 40 being electrically isolated from each connector 13. In other embodiments, the conductive elements 40 are spaced apart from the connectors 13 with at least two conductive elements 40 positioned between two connectors 13, and each conductive element 40 is electrically isolated from each connector 13.

In summary, in the energy storage power supply of the present application, the connecting piece 13 disposed on the housing 10 can partially extend into the mounting hole 21 of the circuit board 20 and be combined with the circuit board 20 to fix the relative position between the circuit board 20 and the housing 10, and the cigar lighter 30 can be directly mounted on the housing 10 through the connecting hole 11 and penetrate the circuit board 20. The shell 10, the circuit board 20 and the cigar lighter 30 can be directly mutually installed without adding other structures, the installation mode is simple and the structure is stable, and the cigar lighter 30 is not easy to fall off.
