[0032] The following detailed description is provided in conjunction with specific accompanying drawings and embodiments: Please refer to the following: Figures 1 to 4 ,in, Figure 1 This is a perspective structural diagram of a power supply device provided in some embodiments of this application. Figure 2 for Figure 1 The exploded diagram, Figure 3 for Figure 1 A sectional view along AA, Figure 4 for Figure 3 Enlarged view at point B. The power device provided in this application embodiment includes a battery module 10, a housing assembly 20, a locking structure 30, and an elastic structure 40. The battery module 10 is provided with a first limiting part 111. The housing assembly 20 is provided with a mounting cavity 201 for mounting the battery module 10. The locking structure 30 is rotatably connected to the housing assembly 20 and can rotate to a first position or a second position. When the locking structure 30 is in the first position, it engages with the first limiting part 111 to limit the battery module 10 within the mounting cavity 201. When the locking structure 30 is in the second position, it disengages from the first limiting part 111. The elastic structure 40 is connected to the locking structure 30 and the housing assembly 20 and provides an elastic force to the locking structure 30 to maintain it in the first position.

[0033] Battery module 10 refers to the module structure of battery 12 for power supply, and battery module 10 includes battery 12.

[0034] The first limiting part 111 is a part of the battery module 10, that is, the battery module 10 includes the first limiting part 111. The first limiting part 111 is used to limit and cooperate with the locking structure 30.

[0035] The mounting cavity 201 refers to the cavity in the housing assembly 20 for mounting the battery module 10. Specifically, the battery module 10 can enter and exit the mounting cavity 201, that is, the battery module 10 can enter the mounting cavity 201 from the outside and can also be removed from the mounting cavity 201.

[0036] The locking structure 30 refers to the structure used to lock the battery module 10 within the mounting cavity 201. The locking structure 30 is rotatable to a first position or a second position, meaning that the locking structure 30 has a first position and a second position. When the locking structure 30 rotates relative to the housing assembly 20, it can rotate to either the first position or the second position.

[0037] Specifically, when the battery module 10 is located within the mounting cavity 201 and the locking structure 30 is in the first position, the locking structure 30 engages with the first limiting part 111 of the battery module 10, causing the battery module 10 to be limited to being within the mounting cavity 201 under the limiting action of the locking structure 30 and the first limiting part 111. At this time, under the limiting action of the locking structure 30 and the first limiting part 111, the battery module 10 cannot be detached from the mounting cavity 201.

[0038] Specifically, when the locking structure 30 is in the second position, the locking structure 30 disengages from the first limiting part 111, that is, the limiting engagement between the locking structure 30 and the first limiting part 111 is removed. At this time, the battery module 10 is not limited by the locking structure 30, allowing the battery module 10 to be detached from the mounting cavity 201.

[0039] Elastic structure 40 refers to a structure with elastic properties. Elastic structure 40 can be a spring, sheet metal, tension spring, etc.

[0040] The elastic structure 40 provides an elastic force to the locking structure 30 to maintain it in the first position. This means that the elastic structure 40 provides an elastic force to the locking structure 30 so that the locking structure 30 is held in the first position under the action of the elastic force of the elastic structure 40. In this way, the locking structure 30 and the first limiting part 111 maintain a limiting engagement relationship, thus limiting the battery module 10 within the mounting cavity 201.

[0041] The power supply device provided in this application embodiment uses an elastic structure 40 to provide an elastic force to the locking structure 30 to maintain it in a first position. When the locking structure 30 is in the first position, it engages with the first limiting part 111 of the battery module 10 to limit it. This allows the locking structure 30 to maintain itself in the first position under the elastic force of the elastic structure 40 when the battery module 10 is located in the mounting cavity 201, thereby limiting the battery module 10 and keeping it within the mounting cavity 201.

[0042] The locking structure 30 is rotatably connected to the housing assembly 20 and can rotate to either a first or a second position. In the second position, the locking structure 30 disengages from the first limiting part 111, allowing it to rotate relative to the housing assembly 20 to the second position under external force. This disengages the locking structure 30 from the first limiting part 111, thus removing its limiting effect on the battery module 10. In this way, the user can remove the locking structure 30's limiting effect on the battery module 10 by applying external force, allowing the battery module 10 to be removed from the mounting cavity 201. This makes the installation and removal of the battery module 10 very simple and convenient.

[0043] It should be further explained that when the battery module 10 is not located within the mounting cavity 201, the locking structure 30 is in the first position under the elastic action of the elastic structure 40. During the process of inserting the battery module 10 into the mounting cavity 201, the locking structure 30 can be rotated by the pressure of the battery module 10 to reach the second position. When the battery module 10 moves into place within the mounting cavity 201, the locking structure 30 rotates back to the first position under the elastic action of the elastic structure 40, thus limiting the battery module 10 within the mounting cavity 201 under the limiting action of the locking structure 30. Based on this, the operation of inserting the battery module 10 into the mounting cavity 201 is very simple, requiring no additional external force to be applied to the locking structure 30.

[0044] In some embodiments, please refer to the following: Figures 2 to 5 And in conjunction with other accompanying figures. Figure 5 This is a perspective view of the locking structure 30 of a power supply device provided in some embodiments of this application. The locking structure 30 includes a pivot portion 31, a pressing portion 32, and a second limiting portion 33. The pivot portion 31 is rotatably connected to the housing assembly 20. The pressing portion 32 is disposed on the pivot portion 31, and at least a portion of the pressing portion 32 is exposed outside the housing assembly 20. The second limiting portion 33 is disposed on the pivot portion 31. In the first position, the second limiting portion 33 engages with the first limiting portion 111. In the second position, the second limiting portion 33 disengages from the first limiting portion 111.

[0045] The pivot portion 31 is the part of the locking structure 30 used for rotatable connection with the housing assembly 20. The pressing portion 32 and the second limiting portion 33 are both provided on the pivot portion 31, and the pivot portion 31, the pressing portion 32 and the second limiting portion 33 can rotate synchronously relative to the housing assembly 20.

[0046] The pressing part 32 is the portion of the locking structure 30 that is subjected to external force. At least a portion of the pressing part 32 is exposed outside the housing assembly 20, allowing the user to apply external force to the pressing part 32, specifically by pressing it. When the pressing part 32 is pressed, the pressing part 32, the pivot part 31, and the second limiting part 33 rotate synchronously, moving from a first position to a second position. When the pressing part 32 is not pressed, the pressing part 32, the pivot part 31, and the second limiting part 33 can be reset and rotated under the elastic force of the elastic structure 40, moving from the second position to the first position.

[0047] The second limiting part 33 is a portion of the locking structure 30 used for limiting engagement with the first limiting part 111. Specifically, when the battery module 10 is located within the mounting cavity 201 and the locking structure 30 is in the first position, the second limiting part 33 engages with the first limiting part 111, such that the lower limit of the battery module 10 under the limiting engagement of the first limiting part 111 and the second limiting part 33 is located within the mounting cavity 201. When the locking structure 30 is in the second position, the second limiting part 33 disengages from the first limiting part 111, meaning the limiting engagement between the second limiting part 33 and the first limiting part 111 is removed.

[0048] By adopting the above technical solution, the user can switch the locking structure 30 to the second position by pressing the pressing part 32, which makes it easier for the battery module 10 to be removed from the mounting cavity 201, thus simplifying the disassembly and assembly of the battery module 10 and the housing assembly 20.

[0049] In some embodiments, please refer to the following: Figures 2 to 4 And in conjunction with other accompanying drawings. The housing assembly 20 includes a pivot shaft 221, and the pivot portion 31 is rotatably connected to the housing assembly 20 via the pivot shaft 221.

[0050] In some possible designs, the pivot portion 31 is rotatably sleeved on the outside of the pivot shaft 221. Specifically, the pivot portion 31 is sleeved on the outer periphery of the pivot shaft 221, and the pivot portion 31 can rotate relative to the pivot shaft 221.

[0051] In some embodiments, please refer to the following: Figures 2 to 4 And in conjunction with other accompanying drawings. The elastic structure 40 abuts between the pressing part 32 and the housing assembly 20.

[0052] Alternatively, in other embodiments, the elastic structure 40 abuts between the second limiting portion 33 and the housing assembly 20.

[0053] Alternatively, in some other embodiments, the elastic structure 40 is sleeved between the pivot shaft 221 and the pivot portion 31, and the two ends of the elastic structure 40 are respectively connected to the pivot portion 31 and the pivot shaft 221.

[0054] The elastic structure 40 can be a spring or a tension spring, such that the elastic structure 40 is sleeved between the pivot shaft 221 and the pivot part 31.

[0055] By adopting the above technical solution, the arrangement of the elastic structure 40 can be very flexible.

[0056] In some embodiments, please refer to the following: Figures 2 to 6 And in conjunction with other accompanying figures. Figure 6 This is a perspective view of the housing assembly 20 and the locking structure 30 of the power supply device provided in some embodiments of this application. The housing assembly 20 has an opening 202 at one end along the first direction Y, and the opening 202 is used for the battery module 10 to enter and exit the mounting cavity 201 along the first direction Y.

[0057] Understandably, the battery module 10 can enter the mounting cavity 201 through the opening 202 along the first direction Y, and can also exit the mounting cavity 201 through the opening 202 along the first direction Y.

[0058] In some embodiments, please refer to the following: Figures 2 to 6 And in conjunction with other accompanying drawings. The pressing part 32 is located on one side of the battery module 10 along the second direction X. In the first position, the locking structure 30 has the second limiting part 33 abutting against the first limiting part 111's first side surface 102 facing the opening 202 along the first direction Y. In the second position, the locking structure 30 has the second limiting part 33 disengaging from the first limiting part 111 along the second direction X. The first direction Y and the second direction X are perpendicular, and both the first direction Y and the second direction X are perpendicular to the rotation axis of the pivot part 31.

[0059] For ease of description, the rotation axis of the pivot 31 is defined as the third direction Z. That is, the first direction Y is perpendicular to the second direction X, the first direction Y is perpendicular to the third direction Z, and the second direction X is perpendicular to the third direction Z. Here, the first direction Y is the approximate orientation of the opening 202, and the second direction X is the approximate distribution direction of the pressing part 32 and the battery module 10.

[0060] Understandably, the first limiting part 111 and the opening 202 are distributed along the first direction Y, and the side of the first limiting part 111 facing the opening 202 along the first direction Y is the first side surface 102. When the battery module 10 is located in the mounting cavity 201 and the locking structure 30 is in the first position, the second limiting part 33 abuts against the first side surface 102, so that the first limiting part 111 cannot be dislodged from the opening 202 along the first direction Y under the abutment action of the second limiting part 33.

[0061] When the locking structure 30 is in the second position, the second limiting part 33 disengages from the first limiting part 111 along the second direction X, so that the second limiting part 33 and the first limiting part 111 are distributed along the second direction X. At this time, the second limiting part 33 does not abut against the first side 102, thereby allowing the battery module 10 to be disengaged from the opening 202 along the first direction Y.

[0062] This design makes the cooperation structure between the locking structure 30 and the first limiting part 111 very simple.

[0063] In some embodiments, please refer to the following: Figures 2 to 6 And in conjunction with other accompanying drawings. The pivot portion 31 and the pressing portion 32 are located on the same side of the battery module 10 along the second direction X.

[0064] Furthermore, when the locking structure 30 is in the second position, the pivot part 31, the pressing part 32, and the second limiting part 33 are located on the same side of the battery module 10 along the second direction X.

[0065] It should be noted that the pressing part 32 and the second limiting part 33 are provided on both sides of the pivot part 31 along the first direction Y.

[0066] In some embodiments, please refer to the following: Figures 4 to 8 And in conjunction with other accompanying figures. Figure 7 This is a perspective structural view of the battery module 10 of the power supply device provided in some embodiments of this application. Figure 8 for Figure 7 Enlarged view at point C. In the direction of the battery module 10 along the second direction X toward the pressing part 32, the first side 102 extends away from the opening 202 along the first direction Y.

[0067] Understandably, the first inclined surface extends from the battery module 10 in the direction of the second direction X toward the pressing part 32, and extends from the opening 202 in the direction of the first direction Y toward the first side surface 102.

[0068] The first side surface 102 can be an inclined surface or an arc surface.

[0069] This configuration allows the first side 102 to avoid the second limiting part 33, facilitating the rotation of the second limiting part 33 to the first side 102 and also facilitating its rotation to disengage from the first limiting part 111. This prevents interference between the first limiting part 111 and the second limiting part 33 during the rotation of the locking structure 30 between the first and second positions.

[0070] In some embodiments, please refer to the following: Figures 4 to 8In conjunction with other accompanying drawings, the battery module 10 has a limiting groove 101 on the side near the pressing part 32 along the second direction X, and the wall of the limiting groove 101 on the side away from the opening 202 along the first direction Y forms a first limiting part 111.

[0071] The limiting groove 101 may be, but is not limited to, a groove formed on the side of the battery module 10 along the second direction X near the pressing part 32.

[0072] Understandably, the first limiting part 111 is a structure formed on the side wall of the limiting groove 101 away from the opening 202 along the first direction Y.

[0073] This design makes the molding of the first limiting part 111 very simple.

[0074] In some embodiments, please refer to the following: Figures 4 to 8 In conjunction with other accompanying drawings, the limiting groove 101 has a first groove wall 104 on the side of the opening 202 along the first direction Y, and the second limiting part 33 has a relief groove 301 on the side of the battery module 10 along the second direction X. At least a portion of the first groove wall 104 is inserted into the relief groove 301 along the second direction X.

[0075] Understandably, the first side 102 and the first groove wall 104 are the two side groove walls of the limiting groove 101 that are opposite each other along the first direction Y, and the first side 102 and the first groove wall 104 are arranged opposite each other along the first direction Y.

[0076] A clearance groove 301 is provided on the side of the second limiting part 33 along the second direction X near the battery module 10, allowing the second limiting part 33 to avoid the first groove wall 104 on the limiting groove 101. This ensures that when the locking structure 30 is in the first position, the first groove wall 104 is spaced apart from the second limiting part 33, and when the locking structure 30 is in the second position, the first groove wall 104 is also spaced apart from the second limiting part 33. This arrangement improves the problem of interference between the second limiting part 33 and the first groove wall 104 during the rotation of the locking structure 30 between the first and second positions.

[0077] In some embodiments, please refer to the following: Figures 2 to 6 In conjunction with other accompanying drawings, the housing assembly 20 includes a housing 21 and a mounting bracket 22, the mounting bracket 22 being disposed within the housing 21 and forming a mounting cavity 201 with the housing 21.

[0078] The locking structure 30 is rotatably connected to the mounting bracket 22. Specifically, the pivot part 31 is rotatably connected to the mounting bracket 22.

[0079] In some embodiments, please refer to the following: Figures 2 to 9 And in conjunction with other accompanying figures. Figure 9This is a perspective view of the mounting bracket 22 and locking structure 30 of the power supply device provided in some embodiments of this application. At least a portion of the mounting bracket 22 is disposed on one side of the battery module 10 along the second direction X. A pivot portion 31 is rotatably connected to the mounting bracket 22, and an elastic structure 40 abuts against the pressing portion 32 and the mounting bracket 22. The locking structure 30 also includes a fourth limiting portion 34 disposed on the second limiting portion 33, the fourth limiting portion 34 extending beyond the second limiting portion 33 along the third direction Z, and limited to the side of the mounting bracket 22 away from the battery module 10 along the second direction X. The third direction Z is parallel to the rotation axis of the pivot portion 31.

[0080] Understandably, in the second direction X, at least a portion of the mounting bracket 22 is disposed between the pivot portion 31 and the battery module 10, and in the second direction X, at least a portion of the mounting bracket 22 is disposed between the pressing portion 32 and the battery module 10. The mounting bracket 22 is provided with a through groove 204 extending along the second direction X, and the through groove 204 is disposed opposite to the first limiting portion 111 along the second direction X. The second limiting portion 33 passes through the through groove 204, allowing the second limiting portion 33 to engage with the first limiting portion 111 for limiting.

[0081] Understandably, the fourth limiting part 34 is positioned on the mounting bracket 22 along the second direction X toward the battery module 10. That is, when the locking structure 30 is in the first position, the fourth limiting part 34 abuts against the mounting bracket 22 along the second direction X toward the battery module 10, thereby limiting the travel of the locking structure 30 to the first position. This improves the problem of the battery module 10 being damaged due to the locking structure 30 continuing to rotate after reaching the first position.

[0082] Specifically, the mounting bracket 22 may include a first bracket and a second bracket, with the second bracket mounted on the first bracket. The first bracket is located on one side of the battery module 10 along the second direction X, and the second bracket is located on one side of the battery module 10 along the first direction Y. A pivot portion 31 is rotatably connected to the first bracket, and both the pivot portion 31 and the pressing portion 32 are located on the side of the first bracket away from the battery module 10 along the second direction X. A second limiting portion 33 is located along the second direction X on the side of the first bracket away from the battery module 10.

[0083] Specifically, the second circuit board assembly 50, as described below, is located on the second frame.

[0084] In some embodiments, please refer to the following: Figure 6 and Figure 7 And in conjunction with other accompanying drawings. One of the battery module 10 and the housing assembly 20 is provided with a guide groove, and the other is provided with a guide rail for entering and exiting the mounting cavity 201 along the guide groove.

[0085] Understandably, the guide rail extends along the first direction Y, and the guide groove extends along the first direction Y.

[0086] Specifically, the guide rail is confined within the guide groove along the second direction X, allowing the guide rail to move along the guide groove in the first direction Y, so that the battery module 10 can stably enter and exit the mounting cavity 201.

[0087] Please refer to the following in some possible designs. Figure 6 and Figure 7 And in conjunction with other accompanying drawings. The guide rail includes a first guide rail 113, and the guide groove includes a first guide groove 203. The first guide rail 113 is disposed on the battery module 10 and is spaced apart from the first limiting part 111. The first guide groove 203 is disposed on the housing assembly 20 and is connected to the opening 202.

[0088] Specifically, the first guide groove 203 is disposed on the mounting bracket 22, and the first guide rail 113 is disposed on the battery casing 11 of the battery module 10.

[0089] Please refer to the following in some possible designs. Figure 6 and Figure 7 And in conjunction with other accompanying drawings. The guide rail includes a second guide rail 222, and the guide groove includes a second guide groove 103. The second guide rail 222 is disposed on the housing assembly 20, and the second guide groove 103 is disposed on the battery module 10, and is spaced apart from the first limiting part 111.

[0090] Specifically, the second guide rail 222 is disposed on the mounting bracket 22, and the second guide groove 103 is disposed on the battery casing 11 of the battery module 10.

[0091] The first guide rail 113 and the second guide groove 103 are alternately distributed along the second direction X, and the second guide rail 222 and the first guide groove 203 are alternately distributed along the second direction X.

[0092] This configuration allows the battery module 10 to stably enter and exit the mounting cavity 201 along the first direction Y, thanks to the cooperation between the guide rail and the guide groove.

[0093] In some embodiments, please refer to the following: Figures 1 to 3 And in conjunction with other accompanying drawings. The battery module 10 includes a battery housing 11, a battery 12, a first circuit board assembly 13, and a charging interface 14. The battery housing 11 has a first limiting part 111, and the battery 12 is disposed inside the battery housing 11. The first circuit board assembly 13 is disposed inside the battery housing 11 and is electrically connected to the battery 12. The charging interface 14 is disposed on the battery housing 11 and is electrically connected to the first circuit board assembly 13.

[0094] Understandably, battery module 10 is a module that integrates battery 12 and charging interface 14.

[0095] With this configuration, after the battery module 10 is removed from the mounting cavity 201, it can be charged independently via the charging interface 14. That is, when the battery module 10's power is insufficient, the locking structure 30 can be pressed to remove the battery module 10 from the mounting cavity 201, and then a fully charged battery module 10 can be replaced. The removed battery module 10 can then be charged independently. This makes the power supply device very convenient to use.

[0096] Furthermore, the charging interface 14 can be exposed outside the housing assembly 20. In this way, the battery module 10 can also be charged through the charging interface 14 when it is confined within the mounting cavity 201.

[0097] In some embodiments, please refer to the following: Figures 2 to 4 In conjunction with other accompanying drawings, the power supply device also includes a second circuit board assembly 50 disposed within the housing assembly 20. The second circuit board assembly 50 is provided with a first conductive terminal 51 and a second conductive terminal 52. The first conductive terminal 51 is connected to the battery module 10, and the second conductive terminal 52 is connected to the atomizing assembly.

[0098] The first conductive terminal 51 and the second conductive terminal 52 are two conductive terminals on the second circuit board assembly 50. The first conductive terminal 51 and the second conductive terminal 52 can be conductive structures such as spring pins or spring contacts.

[0099] Understandably, when the battery module 10 is installed in the mounting cavity 201, the first conductive terminal 51 is connected to the battery module 10, specifically, the first conductive terminal 51 is connected to the conductive terminal on the first circuit board assembly 13, thereby making the second circuit board assembly 50 and the battery module 10 electrically connected.

[0100] When the atomizing component is installed in the power supply device, the second conductive terminal 52 and the atomizing component are connected, thus electrically connecting the atomizing component and the second circuit board assembly 50, thereby achieving electrical connection between the atomizing component and the power supply device. Based on this, the second circuit board assembly 50 can control the battery module 10 to supply power to the atomizing component.

[0101] This configuration ensures that when the battery module 10 is detached from the mounting cavity 201, the first conductive terminal 51 disconnects from the battery module 10 without establishing electrical connection. When the battery module 10 is installed inside the mounting cavity 201, the first conductive terminal 51 connects with the battery module 10, establishing an electrical connection between the second circuit board assembly 50 and the battery module 10. This allows the second circuit board assembly 50 to easily connect with the atomizing component and the battery module 10.

[0102] The aerosol generating device provided in this embodiment includes an atomizing component and a power supply. The atomizing component is mounted on the power supply and electrically connected to it. The power supply in this embodiment is the same as that in the previous embodiments; please refer to the relevant descriptions of the power supply in the previous embodiments for details, which will not be repeated here.

[0103] Specifically, the atomizing component is mounted on the housing component 20.

[0104] Specifically, when the atomizing component is installed on the housing component 20, the atomizing component is connected to the second conductive terminal 52 to achieve electrical connection between the atomizing component and the power supply device.

[0105] The aerosol generating device provided in this application embodiment uses the power supply device involved in the above embodiments, making the disassembly and assembly of the battery module 10 very simple and convenient.

[0106] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
