[0035] The following is a detailed description with reference to the accompanying drawings and embodiments:

[0036] The embodiment of the present application provides a container device for locks, lamps, audio equipment, etc., and for accommodating working parts such as batteries, lamps, speakers, etc. For example, the container device can be applied to locks, mainly for accommodating batteries to achieve waterproof protection for the batteries.

[0037] In one embodiment of the present application, see Figures 1 to 3 The housing 10 is provided with a receiving cavity 11 and an installation opening 12. The installation opening 12 is connected to the receiving cavity 11. The first sealing cover 20 is sealed at the installation opening 12. The interface 40 is provided at the first sealing cover 20. The interface 40 is exposed to the side of the first sealing cover 20 away from the receiving cavity 11. The second sealing cover 30 is connected to the first sealing cover 20. The second sealing cover 30 can be rotated relative to the first sealing cover 20 to the side of the first sealing cover 20 away from the receiving cavity 11 to seal the interface 40.

[0038] The accommodating cavity 11 is used to install working parts such as batteries and speakers to provide waterproof protection for the working parts.

[0039] The first sealing cover 20 and the housing 10 can be connected by means of snap connection, bolt connection, etc.

[0040] In one implementation, the first sealing cover 20 may be interference-fitted with the mounting opening 12 to eliminate the mounting gap between the first sealing cover 20 and the mounting opening 12, thereby achieving the sealing effect of the first sealing cover 20 on the mounting opening 12, thereby achieving the sealing of the accommodating cavity 11. Alternatively, in another implementation, the first sealing cover 20 may also be bonded with the mounting opening 12 by an adhesive to fill the mounting gap between the first sealing cover 20 and the mounting opening 12, thereby achieving the sealing effect of the first sealing cover 20 on the mounting opening 12, thereby achieving the sealing of the accommodating cavity 11. The sealing method between the first sealing cover 20 and the mounting opening 12 is not limited to the above method and may also be other forms, which will not be described in detail here.

[0041] In a possible design, the first sealing cover 20 and the second sealing cover 30 are integrally formed and made of elastic materials such as rubber, silicone, plastic, etc. The first sealing cover 20 and the second sealing cover 30 can be relatively bent so that the second sealing cover 30 rotates relative to the first sealing cover 20. When the second sealing cover 30 rotates, the second sealing cover 30 is always connected to the first sealing cover 20, reducing the risk of losing the second sealing cover 30. Alternatively, in another possible design, the first sealing cover 20 and the second sealing cover 30 are respectively fixed to the two ends of the hinge to be connected by the hinge. The arrangement of the first sealing cover 20 and the second sealing cover 30 is not limited to the above two, and can also be other forms.

[0042] In the accommodating device provided by the embodiment of the present application, the first sealing cover 20 seals the installation port 12 of the housing 10, thereby achieving the sealing of the accommodating chamber 11. The interface 40 is arranged on the first sealing cover 20 and is exposed to the side of the first sealing cover 20 away from the accommodating chamber 11. When the interface 40 needs to be used, the second sealing cover 30 can be rotated to the side away from the first sealing cover 20 away from the accommodating chamber 11, so that the interface 40 is exposed to the outside. Then, the connector of the outside can be electrically connected to the interface 40. When the connector does not need to be connected, the user drives the second sealing cover 30 to rotate relative to the first sealing cover 20, so that the second sealing cover 30 rotates to the side of the first sealing cover 20 away from the accommodating chamber 11, and the interface 40 can be sealed. In this way, the first sealing cover 20 can seal the installation port 12 of the housing 10, so that it is not easy for external moisture to enter the accommodating chamber 11 through the installation port 12, thereby improving the sealing effect of the accommodating device. When the interface 40 is not connected to the connector, the second sealing cover 30 can further seal the interface 40, so that it is not easy for moisture to enter the interface 40. Based on this, the first sealing cover 20 and the second sealing cover 30 cooperate with each other to reduce the risk of moisture or even water ingress into the containing device.

[0043] In some embodiments of this application, please refer to Figure 1 and Figure 2 The first sealing cover 20 elastically abuts against the inner peripheral wall of the installation opening 12 .

[0044] The first sealing cover 20 can be made of elastic materials such as rubber, silicone, plastic, etc.

[0045] The first sealing cover 20 can be elastically deformed. When covering the opening, the first sealing cover 20 can be elastically supported against the wall of the housing 10 by its own deformation to achieve interference fit with the housing 10, thereby improving the waterproof sealing effect of the first sealing cover 20 on the opening. At the same time, the first sealing cover 20 can be elastically deformed, which improves the wear resistance and bending resistance of the first sealing cover 20 and reduces the risk of damage to the first sealing cover 20.

[0046] In some embodiments of this application, please refer to Figures 1 to 3 The first sealing cover 20 is provided with a mounting hole 21 . The interface 40 passes through the mounting hole 21 . The inner peripheral wall of the mounting hole 21 elastically abuts against the interface 40 .

[0047] The first sealing cover 20 can undergo elastic deformation. When the accommodating device is in use, the external connector is plugged into the interface 40, and the inner wall of the mounting hole 21 can be deformed and elastically pressed against the interface 40 to achieve an interference fit with the interface 40, so that moisture is not easy to enter the accommodating cavity 11 through the gap between the inner wall of the mounting hole 21 and the interface 40, thereby improving the sealing effect of the accommodating device.

[0048] In some embodiments of this application, please refer to Figure 1 The second sealing cover 30 includes a cover body 31 and a sealing block 32. The cover body 31 is connected to the first sealing cover 20 and can rotate relative to the first sealing cover 20. The sealing block 32 is arranged on the cover body 31. At least a part of the sealing block 32 can be inserted into the interface 40 and elastically abut against the inner peripheral wall of the interface 40.

[0049] The sealing block 32 may be made of a waterproof material such as rubber, silicone, or plastic.

[0050] When the second sealing cover 30 rotates to the side of the first sealing cover 20 away from the accommodating chamber 11, the sealing block 32 of the second sealing cover 30 can be inserted into the interface 40, so that the second sealing cover 30 can better seal the interface 40, and moisture is not easy to enter the interface 40, thereby reducing the risk of water ingress into the interface 40.

[0051] In one embodiment of the present application, see Figure 3 The first sealing cover 20 is provided with a first positioning member. The second sealing cover 30 is provided with a first positioning hole. The first positioning member can be inserted into the first positioning hole.

[0052] It can be understood that when the second sealing cover 30 seals the interface 40 , the first positioning member is inserted into the first positioning hole.

[0053] The first positioning member may be, but is not limited to, a screw, a boss, etc.

[0054] The number of the first positioning member can be selected as one. Alternatively, the first sealing cover 20 can also be provided with a plurality of first positioning members. Accordingly, the number of the first positioning holes can be set corresponding to the number of the first positioning members.

[0055] The first sealing cover 20 and the second sealing cover 30 are positioned by the mating and plugging of the first positioning member and the first positioning hole. When the second sealing cover 30 seals the interface 40, the second sealing cover 30 can be accurately installed on the first sealing cover 20, thereby optimizing the manufacturing and assembly process of the receiving device. At the same time, the situation that the waterproof effect is weakened due to the relative displacement of the first sealing cover 20 and the second sealing cover 30 when the receiving device is in use is also improved.

[0056] Alternatively, in another embodiment, the second sealing cover 30 is provided with a second positioning member 33. The first sealing cover 20 is provided with a second positioning hole 23. The second positioning member 33 can be inserted into the second positioning hole 23.

[0057] The second positioning member 33 may be, but is not limited to, a screw, a boss, etc.

[0058] The number of the second positioning member 33 can be selected as one. Alternatively, the second sealing cover 30 can also be provided with a plurality of second positioning members 33. Accordingly, the number of the second positioning holes 23 can be set corresponding to the number of the second positioning members 33.

[0059] The first sealing cover 20 and the second sealing cover 30 are positioned by the second positioning member 33 and the second positioning hole 23. When the second sealing cover 30 seals the interface 40, the second sealing cover 30 can be accurately installed on the first sealing cover 20, which optimizes the manufacturing and assembly process of the receiving device. At the same time, it also improves the situation that the waterproof effect is weakened due to the relative displacement of the first sealing cover 20 and the second sealing cover 30 when the receiving device is in use.

[0060] Alternatively, in another embodiment, the first sealing cover 20 is provided with a first positioning member and a second positioning hole 23. The second sealing cover 30 is provided with a second positioning member 33 and a first positioning hole. When in use, the first positioning member can be inserted into the first positioning hole, and the second positioning member 33 can be inserted into the second positioning hole 23, further improving the positioning effect between the first sealing cover 20 and the second sealing cover 30.

[0061] In some embodiments of this application, please refer to Figures 1 to 3, the first sealing cover 20 is provided with a first limiting groove 22. The first limiting groove 22 is located on a side of the first sealing cover 20 away from the accommodating chamber 11. The interface 40 is located in the first limiting groove 22. When the second sealing cover 30 seals the interface 40, at least part of the second sealing cover 30 is accommodated in the first limiting groove 22. The second sealing cover 30 is also limited by the groove wall of the first limiting groove 22.

[0062] The first sealing cover 20 can be provided with a protrusion to enclose and form a first limiting groove 22. For example, Figure 3 As shown, the first sealing cover 20 is provided with an arc-shaped convex strip 24 on one side away from the accommodating cavity 11, and the convex strip 24 encloses the first limiting groove 22. When the second sealing cover 30 seals the interface 40, the second sealing cover 30 is at least partially accommodated in the first limiting groove 22 and limited by the convex strip 24.

[0063] In this way, the second sealing cover 30 is limited by the groove wall of the first limiting groove 22, so that the second sealing cover 30 can be accurately installed on the first sealing cover 20, thereby improving the positioning effect between the first sealing cover 20 and the second sealing cover 30 and optimizing the processing, manufacturing and assembly process of the containing device.

[0064] In some embodiments of this application, please refer to Figures 2 to 4 The accommodating device further comprises a connecting structure 50. The connecting structure 50 is provided on the first sealing cover 20. The connecting structure 50 is accommodated in the accommodating cavity 11. At least a part of the housing 10 is limited to the connecting structure 50 to fix the first sealing cover 20 to the housing 10.

[0065] The connection structure 50 can be connected to the first sealing cover 20 by bolt connection, bonding, clamping, welding, etc.

[0066] In a possible design, the shell 10 is provided with an extension portion 13, and the extension portion 13 is limited to the connecting structure 50 along the first direction Z. The connecting structure 50 includes a main body 51 and a limiting portion 52. At least a portion of the limiting portion 52 is spaced apart from the main body 51 along the first direction Z to form a second limiting groove 53. The extension portion 13 is limited to the groove wall of the second limiting groove 53 along the first direction Z, and is respectively abutted against the main body 51 and the limiting portion 52 on opposite sides along the first direction Z. Specifically, the number of the limiting portions 52 can be one or more, which is not limited here. When the limiting portions 52 are set to multiple, the multiple limiting portions 52 are spaced apart on the main body 51, and are spaced apart from the main body 51 along the first direction Z to form multiple second limiting grooves 53.

[0067] Among them, the first direction Z is as follows Figure 2 The direction Z is indicated in FIG.

[0068] It should be noted that the X-axis, Y-axis and Z-axis constitute a spatial coordinate system, the X-axis, Y-axis and Z-axis are three coordinate axes of the spatial coordinate system, the X-axis is perpendicular to the Y-axis, the X-axis is perpendicular to the Z-axis, and the Y-axis is perpendicular to the Z-axis. Figure 2 As shown, the first direction Z is parallel to the Z axis.

[0069] In this way, at least part of the shell 10 is limited to the connection structure 50. Since the connection structure 50 is arranged on the first sealing cover 20, the shell 10 is not easy to separate from the first sealing cover 20, thereby improving the stability and reliability of the connection between the first sealing cover 20 and the shell 10.

[0070] In some embodiments of this application, please refer to Figure 2 A metal sheet 60 is disposed inside the first sealing cover 20 .

[0071] The metal sheet 60 may be a copper sheet, a steel sheet, an iron sheet, or the like.

[0072] The metal sheet 60 is provided in the first sealing cover 20 , so that the structural strength of the first sealing cover 20 is improved, so that the first sealing cover 20 is not easily damaged by external force, and the wear resistance and durability of the first sealing cover 20 are improved.

[0073] In some embodiments of this application, please refer to Figure 1 and Figure 2 The receiving device further includes a fastener 70. The fastener 70 passes through the metal sheet 60, the first sealing cover 20 and the connecting structure 50 to fix the connecting structure 50 to the first sealing cover 20.

[0074] In a possible design, the fastener 70 can be a screw, a bolt or the like, and the metal sheet 60, the first sealing cover 20 and the connecting structure 50 are all provided with screw holes that match the fastener 70. The fastener 70 can pass through the metal sheet 60, the first sealing cover 20 and the connecting structure 50 in sequence.

[0075] The connection structure 50 and the first sealing cover 20 are locked by the fastener 70, which improves the connection strength between the first sealing cover 20 and the connection structure 50, making it difficult for moisture to enter the accommodating cavity 11 through the gap between the two, thereby improving the waterproof effect of the accommodating device.

[0076] In a second aspect, a lock is provided. The lock according to the second aspect of the present application includes a battery and a receiving device. The battery is received in the receiving cavity 11. The battery is used to be electrically connected to the interface 40.

[0077] Among them, the containing device involved in the embodiment of the present application is the same as the containing device involved in the above embodiment. For details, please refer to the relevant description above and will not be repeated here.

[0078] The lock may include a lock handle, a lock shell and a cam member, the lock handle includes a storage device, a battery and an unlocking mechanism, and the battery and the unlocking mechanism are both arranged in the storage device. The lock shell is arranged in the door, the lock handle is inserted into the lock shell, and the cam member is rotatably connected to the lock shell, and the unlocking mechanism can be driven by the power supply of the battery to cooperate with the cam member to stop the rotation, thereby realizing the switch lock operation. The interface 40 is electrically connected to the battery. When the power in the battery is exhausted, the user can connect the charger at the interface 40, and then connect the charger to an external power source to charge the battery.

[0079] In the lock provided by the embodiment of the present application, the first sealing cover 20 can seal the installation opening 12 of the housing 10, so that external moisture is not easy to enter the accommodating cavity 11 through the installation opening 12, thereby improving the sealing effect of the accommodating device. When the interface 40 is not connected to the connector, the second sealing cover 30 can further seal the interface 40, so that moisture is not easy to enter the interface 40. Based on this, the first sealing cover 20 and the second sealing cover 30 cooperate to reduce the risk of moisture or even water ingress into the battery of the lock, thereby improving the reliability of the lock.
