Example one

Please refer to fig. 1 to fig. 3, fig. 1 is a schematic structural diagram of a housing assembly (a second housing is covered outside a first housing) according to a first embodiment of the present invention, fig. 2 is a schematic structural diagram of the housing assembly (the second housing is opened to expose the first housing by sliding relative to the first housing) according to a first embodiment of the present invention. The embodiment of the utility model provides a disclose a casing subassembly 100, it can be applied to in the box body structure, for example can be applied to in the earphone box that charges. The embodiment of the utility model provides an use casing subassembly to be applied to earphone box of charging to explain as the example. Specifically, the housing assembly 100 includes a first housing 11, a second housing 12, a first transmission member 131 and a second transmission member 132, wherein the first transmission member 131 is fixedly connected to the first housing 11, and the second transmission member 132 is fixedly connected to the second housing 12. The first transmission member 131 is in transmission connection with the second transmission member 132. The second housing 12 is disposed outside the first housing 11, and the first transmission member 131 drives at least a portion of the second housing 12 to move through the second transmission member 132, so that the second housing 12 covers the first housing 11 or uncovers the first housing 11.

It is understood that the second housing 12 is disposed outside the first housing 11, and then, for this housing assembly, the first housing 11 may serve as an inner housing (hereinafter, the first housing 11 is referred to as the inner housing 11), and the second housing 12 may serve as an outer housing (hereinafter, the second housing 12 is referred to as the outer housing 12). The inner housing 11 is provided with a first receiving slot 110, and the first receiving slot 110 can be used for receiving a wireless headset to charge the wireless headset. The outer housing 12 is slidably covered on the outer portion of the inner housing 11 to cover the first receiving groove 110, so as to prevent impurities or dust from entering the first receiving groove 110 during charging. The first transmission member 131 is disposed in the inner casing 11, the second transmission member 132 is disposed on the outer casing 12 and faces the wall surface of the inner casing 11, and the second transmission member 132 is used for driving at least a portion of the outer casing 12 to slide relative to the inner casing 11, so as to expose at least a portion of the first receiving slot 110 of the inner casing 11.

By adopting the scheme of the embodiment, the first transmission member 131 and the second transmission member 132 are connected in a transmission manner, so that the outer shell 12 can be conveniently opened or closed in a sliding manner relative to the inner shell 11, the earphone can be taken and placed, the taking and placing operations of the earphone are effectively simplified, and the use convenience of a user is improved. In addition, the outer shell 12 does not need to be rotated in a manner that the outer shell 12 slides and opens relative to the inner shell 11, so that the problem that the service life of the shell assembly 100 is influenced due to the fact that the outer shell 12 is loosened relative to the inner shell 11 after multiple times of rotation can be avoided.

It is understood that the first transmission member 131 may be a gear, and the second transmission member 132 may be a rack. Alternatively, the first transmission member 131 may be a lead screw, and the second transmission member 132 may be a slider. No matter the transmission mode of the gear and the rack is adopted or the transmission mode of the screw rod and the sliding block is adopted, the advantages of reliable matching and convenience for operation of a user are achieved.

In some embodiments, in order to prevent the outer shell 12 from being separated from the inner shell 11 during the opening of the outer shell 12 relative to the inner shell 11, a first connecting portion (not shown) may be disposed on the inner shell 11, a second connecting portion (not shown) may be disposed on the outer shell 12 corresponding to the first connecting portion, the second connecting portion is connected to the first connecting portion to connect the outer shell 12 and the inner shell 11 together, and the second connecting portion is movable relative to the first connecting portion during the movement of the outer shell 12. Thus, on the one hand, the outer shell 12 can be smoothly moved relative to the inner shell 11, and on the other hand, the outer shell 12 can be kept connected with the inner shell 11 all the time during the movement.

Alternatively, the first connecting portion may be a fastener, the second connecting portion may be a sliding slot, the first connecting portion is fastened in the sliding slot and can slide relative to the sliding slot, and the moving direction of the housing 12 is along the length direction of the sliding slot, so that the second connecting portion can slide relative to the first connecting portion during the moving process of the housing 12, thereby providing a further guide for the moving of the housing 12 and simultaneously keeping the second connecting portion and the first connecting portion connected together. It is understood that, in other embodiments, the first connecting portion may also be a sliding groove, and in this case, the second connecting portion may be a snap-fit member.

In some embodiments, the inner shell 11 may be a circular shell or an elongated shell, and the arrangement may be adjusted according to actual situations. By way of example, the inner case 11 is an elongated case, such as a rectangular parallelepiped case, so that it has enough space for placing an earphone, and at the same time, enough space for disposing the first transmission member 131.

Further, the first receiving groove 110 may be a circular groove or an elongated groove opened in the inner shell 11, and in a specific configuration, the first receiving groove 110 may be adjusted according to the size of the earphone to be placed or according to the shape of the inner shell 11, for example, when the inner shell 11 is a circular shell, the first receiving groove 110 may be a circular groove, and if the inner shell 11 is an elongated shell, the first receiving groove 110 may be an elongated groove.

In some embodiments, the first transmission member 131 may be disposed in the first receiving slot 110, so that when the outer shell 12 slides open relative to the inner shell 11, a user may view the first transmission member 131, and then the wireless headset may be placed in the first receiving slot 110 at a position where the first transmission member 131 is not disposed. Thus, the space of the first receiving groove 110 can be saved, so that the overall volume of the inner case 11 can be set smaller, and the carrying by a user is facilitated.

In other embodiments, the first transmission member 131 may be disposed at other positions of the inner casing 11. Illustratively, the inner housing 11 further has a second receiving groove (not shown) disposed below the first receiving groove 110 and not communicated with the first receiving groove 110, in other words, the second receiving groove is a closed groove, and the first transmission member 131 can be disposed in the second receiving groove. Therefore, the arrangement position of the first transmission piece 131 and the position for taking and placing the wireless earphones are distinguished, the placement of the wireless earphones can be more random, and meanwhile, the user is prevented from watching the first transmission piece 131. In a specific arrangement, the inner space of the inner casing 11 may be partitioned into the first receiving groove 110 and the second receiving groove by means of a partition, and the opening of the second receiving groove is closed by the partition.

Alternatively, since the outer shell 12 is disposed outside the inner shell 11 and is connected by the first transmission piece 131 and the second transmission piece 132, in order to facilitate the transmission connection between the first transmission piece 131 and the second transmission piece 132, the first opening 111 may be disposed at a position of the inner shell 11 corresponding to the second transmission piece 132, and the first transmission piece 131 may be partially exposed from the first opening 111 to be in transmission connection with the second transmission piece 132, so as to drive the outer shell 12 to slide relative to the inner shell 11. Specifically, the first opening 111 may be in communication with the position of the first transmission member 131, so that the first transmission member 131 is exposed. For example, when the first transmission member 131 is disposed in the first receiving cavity 110, the first opening 111 is communicated with the first receiving cavity 110. When the first transmission member 131 is disposed in the second receiving slot, the first opening 111 is communicated with the second receiving slot.

In some embodiments, the outer shell 12 may be a circular shell or an elongated shell, and may be configured according to the shape of the inner shell 11. For example, when the inner housing 11 is a circular housing, the outer housing 12 may be a circular housing. When the inner housing 11 is an elongated housing, the outer housing 12 may also be an elongated housing.

Further, in order to facilitate the sliding opening of the outer casing 12 relative to the inner casing 11 and save the material of the outer casing 12, the outer casing 12 may include a cover plate 12a and a connecting plate 12b which are vertically arranged, and the cover plate 12a is fixedly connected with the connecting plate 12 b. When the second transmission member 132 is disposed, the second transmission member 132 may be disposed on the connection plate 12b, the cover plate 12a may be moved to cover the second opening of the inner shell 11, and when the first transmission member 131 drives the outer shell 12 to move through the second transmission member 132, the cover plate 12a moves parallel to the second opening above the second opening to cover and uncover the inner shell 11. Specifically, both ends of the outer housing 12 in the length direction of the inner housing 11 are not covered with the inner housing 11, in other words, the outer housing 12 is only disposed on the side of the inner housing 11 having the first receiving groove 110 and the position of the inner housing 11 adjacent to the first receiving groove 110 to facilitate the sliding of the outer housing 12 relative to the inner housing 11. For example, as shown in fig. 2, the inner case 11 is a rectangular case having both end surfaces in the longitudinal direction, the outer case 12 is also a rectangular case, and both ends of the outer case 12 in the longitudinal direction corresponding to the inner case 11 are open ends, that is, both end surfaces in the longitudinal direction of the inner case 11 are not covered by the outer case 12.

In this embodiment, the inner casing 11 and the outer casing 12 are rectangular casings, and the sliding direction of the outer casing 12 relative to the inner casing 11 is along the length direction of the inner casing 11. For example, if the inner housing 11 and the outer housing 12 are rectangular housings, the outer housing 12 can slide along the longitudinal direction of the inner housing 11, and the first receiving groove 110 of the inner housing 11 can be exposed along the longitudinal direction.

Considering that the outer housing 12 can slide open relative to the inner housing 11, when the outer housing 12 slides open relative to the inner housing 11, it can slide open relative to the inner housing 11 as a whole or partially slide open relative to the inner housing 11.

In an alternative embodiment, as shown in fig. 3A, fig. 3A shows that the outer shell 12 is integrally opened by sliding with respect to the inner shell, when the outer shell 12 is integrally opened with respect to the inner shell 11, the outer shell 12 may be an integral shell, and when the second transmission member 132 is in transmission connection with the first transmission member 131, the second transmission member 132 can drive the outer shell 12 to integrally open by sliding with respect to the inner shell 11, so as to expose the first receiving slot 110 of the inner shell 11.

In another alternative embodiment, the outer shell 12 may be a split-type housing when the outer shell 12 is partially slid open relative to the inner shell 11. In particular, the housing 12 comprises a first housing part 120 and a second housing part 121, the first housing part 120 and/or the second housing part 121 being provided with the second transmission member 132. In one example, as shown in FIG. 3B, FIG. 3B shows the first housing portion 120 being opened relative to the inner housing, and when the first housing portion 120 is provided with the second transmission member 132, the first housing portion 120 can be slid open relative to the inner housing 11, and the second housing portion 121 can be unopened relative to the inner housing 11. In another example, as shown in fig. 3C, fig. 3C shows the second housing part 121 being opened with respect to the inner housing 11, and when the second housing part 121 is provided with the second transmission member 132, the second housing part 121 can be slid open with respect to the inner housing 11, and at this time, the first housing part 120 can be unopened with respect to the inner housing 11. In still another example, as shown in fig. 3D, fig. 3D shows that the first and second housing portions 120 and 121 are both opened with respect to the inner case 11, and when the first and second housing portions 120 and 121 are both provided with the second transmission member 132, the first and second housing portions 120 and 121 are both opened by sliding with respect to the inner case 11, or alternatively, only either one of the housing portions is opened by sliding with respect to the inner case 11.

Further, when the first housing portion 120 and the second housing portion 121 are both provided with the second transmission member 132, the first transmission member 131 is a gear, and the second transmission member 132 is a rack, that is, under the driving of the first transmission member 131 and the second transmission member 132, the sliding direction of the first housing portion 120 relative to the inner shell 11 is opposite to the sliding direction of the second housing portion 121 relative to the inner shell 11. For example, as shown in fig. 3D, it can be seen from the foregoing that the inner housing 11 and the outer housing 12 are both elongated housings, so that when a user needs to open the inner housing 11, the first housing portion 120 can be opened by sliding along the first direction X of the long side a of the inner housing 11, and the second housing portion 121 can be opened by sliding along the second direction Y of the long side a of the inner housing 11, so that the first housing portion 120 and the second housing portion 121 are opened in a staggered manner with respect to the inner housing 11 when the first housing portion 120 and the second housing portion 121 are opened. Wherein the first direction X and the second direction Y are opposite directions, for example, as shown in fig. 3D, the first direction X is a direction backward along the long side a of the inner case 11 in fig. 2, and the second direction Y is a direction forward along the long side a of the inner case 11 in fig. 3D. It is understood that the first direction X and the second direction Y are only examples and do not limit the scope of the present embodiment.

It is understood that, in other embodiments, when the first transmission member 131 is a screw rod and the second transmission member 132 is a slider, and the first housing portion 120 and the second housing portion 121 are both provided with the second transmission member 132, the sliding directions of the first housing portion 120 and the second housing portion 121 relative to the inner housing 11 may be the same.

In some embodiments, as shown in fig. 4 and 5, the transmission connection between the first transmission member 131 and the second transmission member 132 can be achieved by a manual push, a knob, or a control.

Alternatively, when the transmission connection between the first transmission member 131 and the second transmission member 132 is realized by a control manner, the realization manner may be: in one example, as shown in fig. 4, a driving mechanism 112 is disposed on the inner housing 11, and the driving mechanism 112 is connected to the first transmission member 131 for driving the first transmission member 131 to rotate. For example, the driving mechanism 112 can be a driving motor, and when the first transmission member 131 is a gear and the second transmission member 132 is a rack, the driving motor can drive the first transmission member 131 to rotate, so that the first transmission member 131 and the second transmission member 132 are engaged with each other to make the second transmission member 132 drive the outer shell 12 to slide open relative to the inner shell 11. Similarly, when the first transmission member 131 is a lead screw and the second transmission member 132 is a slider, the driving motor can drive the lead screw to rotate, so that the second transmission member 132 can slide on the first transmission member 131 to drive the outer shell 12 to slide and open relative to the inner shell 11.

In this example, in order to facilitate the user to control the driving mechanism 112 to drive the first transmission member 131 to rotate, a button may be disposed on the housing 12 for controlling the driving mechanism 112, or the housing assembly 100 may further include a processor 113, the processor 113 is electrically connected to the driving mechanism 112, and the processor 113 may be configured to control the driving mechanism 112 to be turned on or off, so that an application icon for controlling the processor 113 may be disposed on the smart terminal 1 (e.g., a smart phone, a smart watch, a tablet computer, etc.) in communication connection with the housing assembly 100, and the user may control the driving mechanism 112 to start to drive the first transmission member 131 to rotate through clicking, touching, or pressing the application icon by the processor 113.

The mode of automatically controlling the transmission connection between the first transmission member 131 and the second transmission member 132 is adopted, the manual control by a user is not needed, the automation degree is high, the controllability is strong, and the use convenience of the user is improved.

In another example, as shown in fig. 5 and 6, the first transmission member 131 and the second transmission member 132 can be connected in a transmission manner by applying a force manually by a user. In practical applications, the outer shell 12 may be provided with an avoiding hole 122, the housing assembly 100 further includes a knob 14, the knob 14 is disposed at a position corresponding to the avoiding hole 122 of the inner shell 11, and the knob 14 is connected to the first transmission member 131 for driving the first transmission member 131 to rotate. Specifically, the position of the knob 14 on the inner housing 11 may be a side opposite to the opening of the first receiving groove 110, for example, when the side of the inner housing 11 where the first receiving groove 110 is located is a front side, the knob 14 may be located on the back side of the inner housing 11, so that when the knob 14 is not needed to be used, the knob 14 is hidden on the back side of the inner housing 11, which can prevent the user from opening the outer housing 12 by mistake, and meanwhile, the whole housing assembly 100 may be more compact.

In such an example, the diameter of the relief hole 122 may be larger than the outer diameter of the knob 14, thereby facilitating manual operation by a user. Specifically, the avoiding hole 122 may have an operation space 122a at a position corresponding to the outer circumference of the knob 14, and the operation space 122a may be used for a finger of a user to enter so as to facilitate the user to rotate the knob 14. For example, when the knob 14 is a circular knob 14, the avoiding hole 122 may be a circular hole or a strip-shaped hole, such as a rectangular hole or an elliptical hole, so that the avoiding hole 122 may form the operation space 122a at a region other than a position corresponding to the knob 14, thereby facilitating a user's finger to extend from the operation space 122a into the knob 14. It is understood that, in other embodiments, the outer end surface of the knob 14 may be protruded from the avoiding hole 122, so that the aperture of the avoiding hole 122 may be adapted to the outer diameter of the knob 14, and an operation space 122a does not need to be reserved, and a user does not need to extend into the avoiding hole 122 to operate the knob 14, thereby reducing the opening area on the housing 12, and effectively preventing dust from entering the avoiding hole 122.

The outer end surface of the knob 14 is a surface of the knob 14 facing the opening of the avoiding hole 122.

In this example, further, in order to facilitate the user to turn the knob 14, an anti-slip structure 140 may be provided on an outer circumferential surface of the knob 14, so that the friction force of the user to turn the knob 14 can be increased. For example, the anti-slip structure 140 may be an anti-slip rib, an anti-slip bump, or the like.

The following is a brief explanation of the process of opening or closing the outer case 12 of the case assembly 100 by providing the knob 14 on the inner case 11:

opening process: the knob 14 is manually rotated to rotate the first transmission member 131 (e.g. a gear) disposed in the inner housing 11, so as to engage and rotate with respect to the second transmission member 132 (e.g. a rack) on the outer housing 12, so that the first housing part 120 and the second housing part 121 slide and open along the direction of the long side a of the inner housing 11 under the action of the second transmission member 132, and the first receiving slot 110 of the inner housing 11 can be exposed, and at this time, a user can take and place the wireless headset.

Closing process: after the user finishes taking and placing the wireless earphone, the knob 14 is manually rotated again to rotate the gear in the inner housing 11 in the opposite direction, so that the first housing part 120 and the second housing part 121 slide along the direction of the long side a of the inner housing 11 under the action of the rack until the positions of covering the first receiving grooves 110 of the inner housing 11 are restored.

Adopt the embodiment of the utility model provides a shell assembly 100 discloses, through adopting first driving medium 131 and second driving medium 132 transmission complex mode, realize that the slip of the relative inner shell 11 of shell 12 is opened or the slip lid closes, convenient operation and quick is favorable to improving user's the simple operation nature. In addition, the sliding opening mode is adopted without rotating the outer shell 12, so that the problem that the outer shell 12 is loosened relative to the inner shell 11 after multiple times of rotation can be avoided, and the service life of the shell assembly 100 is prolonged.
