In the detailed description of the present application below, certain specific details are described in detail. Those skilled in the art can fully understand the present application without these details. To avoid obscuring the substance of the present application, well-known methods, processes, flows, elements, and circuits are not described in detail.

[0028] Furthermore, those skilled in the art should understand that the accompanying drawings provided herein are for illustrative purposes only and are not necessarily drawn to scale.

[0033] Figure 1 This is a schematic diagram of the storage compartment in the closed state according to an embodiment of the present invention. Figure 2 This is a schematic diagram of the storage compartment in the open state provided in an embodiment of the present invention, as shown below. Figure 1 and Figure 2 As shown, the storage compartment includes an outer shell assembly 1 and an inner shell assembly 3. The inner shell assembly 3 has a storage slot 31 and is movably disposed within the outer shell assembly 1. The storage slot 31 is used to place items. It should be noted that the storage compartment can be used as an electronic device storage compartment to store electronic devices such as headphones and smart glasses, or it can be used to store other types of items. Figure 3 This is a schematic diagram of the structure of the housing assembly provided in an embodiment of the present invention, as shown below. Figure 3As shown, the first end opening of the outer shell assembly 1 forms a receiving cavity 11, and a rack 2 is provided inside the receiving cavity 11. The rack 2 extends from the first end of the outer shell assembly 1 to the second end of the outer shell assembly 1, and the first end and the second end of the outer shell assembly 1 are arranged opposite to each other. It is easy to understand that the inner shell assembly 3 is movably disposed within the receiving cavity 11. Figure 4 This is a schematic diagram of the inner shell assembly provided in an embodiment of the present invention. Figure 5 This is a structural schematic diagram of the inner shell assembly provided in an embodiment of the present invention from another perspective, as shown below. Figure 4 and Figure 5 As shown, the inner shell assembly 3 is equipped with a gear 4. Figure 6 This is a cross-sectional schematic diagram of the storage compartment provided in an embodiment of the present invention, as shown below. Figure 6 As shown, the inner shell assembly 3 is also provided with a coil spring 5, and the two ends of the coil spring 5 are connected to the inner shell assembly 3 and the gear 4 respectively.

[0034] Figure 7 This is a cross-sectional schematic diagram of the storage compartment in the closed state according to an embodiment of the present invention. Figure 8 This is a cross-sectional schematic diagram of the storage compartment in the open state provided in an embodiment of the present invention, as shown below. Figure 7 and Figure 8 As shown, gear 4 meshes with rack 2. It is easy to understand that the coil spring 5 drives gear 4 to roll along rack 2 toward the first end of outer shell assembly 1 through preload, thereby causing inner shell assembly 3 to extend from the receiving cavity 11. It should be noted that the driving force of coil spring 5 can be adjusted by parameters such as its size, thickness, and width. Thus, the storage compartment releases preload through the coil spring to drive gear to roll along rack, achieving the unlocking function with a low-cost, purely mechanical structure. This avoids the vibration problems associated with conventional cover opening and closing methods, and the gear and rack transmission structure effectively prevents malfunctions caused by drops and impacts. Furthermore, the drawer-style structure of the storage compartment allows for unobstructed access to items in the storage slot 31, facilitating user operation.

[0035] Figure 9 This is an exploded view of the outer casing assembly provided in an embodiment of the present invention, as shown below. Figure 3 and Figure 9 As shown, in one embodiment, the housing assembly 1 includes a housing body 12 and a support 13. Specifically, the first end opening of the housing body 12 forms the aforementioned receiving cavity 11, the support 13 is disposed within the receiving cavity 11, and the rack 2 is disposed on the support 13. It is readily understood that the support 13 is generally formed into a U-shaped structure, and two racks 2 are provided and symmetrically distributed on the two arms of the support 13.

[0036] Figure 10 This is an exploded view of the inner shell assembly provided in an embodiment of the present invention, as shown below. Figure 4 , Figure 5 and Figure 10As shown, in one embodiment, the inner shell assembly 3 includes an inner shell body 32 and an inner shell accessory 33. Specifically, a receiving groove 31, a gear 4, and a coil spring 5 are disposed on the inner shell body 32. Meanwhile, the inner shell accessory 33 is connected to the inner shell body 32 from one side and cooperates with the inner shell body 32 to clamp the gear 4 and the coil spring 5, preventing the gear 4 and the coil spring 5 from dislodging from the inner shell assembly 3, and also preventing the gear 4 from wobbling. It is readily understood that two gears 4 and two coil springs 5 ​​are respectively provided and symmetrically distributed on both sides of the inner shell body 32 to match the two racks 2, thereby helping to improve the stability and smoothness of the inner shell assembly 3 during entry and exit.

[0037] like Figure 4 and Figure 5 As shown, in one embodiment, the inner shell assembly 3 is provided with a locking mechanism 6. Specifically, the locking mechanism 6 is provided on the inner shell body 32. It is easy to understand that the locking mechanism 6 is used to lock the inner shell assembly 3 within the receiving cavity 11. That is, when the storage compartment is in the closed state, the inner shell assembly 3 is retracted into the receiving cavity 11 and locked by the locking mechanism 6, so that the storage compartment can remain in the closed state.

[0038] like Figure 3 As shown, in one embodiment, the outer shell assembly 1 is provided with an unlocking mechanism 7. Specifically, the unlocking mechanism 7 is located on the bracket 13. It is easy to understand that the unlocking mechanism 7 is used to trigger the locking mechanism 6 to unlock, thereby allowing the inner shell assembly 3 to extend from the receiving cavity 11. That is, when the unlocking mechanism 7 triggers the locking mechanism 6, the locking mechanism 6 releases the inner shell assembly 3, allowing the inner shell assembly 3 to extend from the receiving cavity 11 under the driving action of the coil spring 5, thereby opening the storage compartment, at which time the storage slot 31 is exposed for taking out and putting in items.

[0039] like Figure 7 , Figure 8 and Figure 10 As shown, in one embodiment, the locking mechanism 6 includes a lock head 61, a first reset member 62, and a first limiting member 63. Specifically, the lock head 61 is movably disposed on the inner shell body 32 of the inner shell assembly 3. Further, the first reset member 62 is disposed on the inner shell body 32 of the inner shell assembly 3 and is configured to drive the lock head 61 away from the inner shell assembly 3. Optionally, the first reset member 62 is configured as a spring or other elastic structure, which drives the lock head 61 to move by its own preload. It should be noted that the retraction and ejection stroke of the lock head 61 can be adjusted according to different designs. Further still, the first limiting member 63 is disposed on the inner shell body 32 of the inner shell assembly 3 and locks the lock head 61 to prevent the lock head 61 from dislodging from the inner shell assembly 3. That is, the first limiting member 63 is used to prevent the lock head 61 from being ejected from the inner shell body 32 by the first reset member 62. Optionally, the first limiting member 63 is configured as a U-shaped retaining spring.

[0040] Figure 11 This is a schematic diagram of the structure of the inner shell body provided in an embodiment of the present invention, as shown below. Figure 11 As shown, the inner shell assembly 3 has a first mounting groove 321 and a first insertion hole 322 communicating with the first mounting groove 321 on its inner shell body 32. Further, a first reset member 62 and a lock head 61 are sequentially disposed within the first mounting groove 321, and a first limiting member 63 is inserted into the first insertion hole 322 to lock the lock head 61. It is easily understood that one end of the first reset member 62 abuts against the bottom of the first mounting groove 321, and the other end abuts against the lock head 61 to push the lock head 61 through its own pre-tightening force, while the first limiting member 63 extends into the first mounting groove 321 through the first insertion hole 322 to limit the lock head 61.

[0041] like Figures 7 to 9 As shown, in one embodiment, the unlocking mechanism 7 includes a mating member 71, a pressing member 72, a second reset member 73, and a second limiting member 74. Specifically, the mating member 71 is disposed on the bracket 13 of the housing assembly 1. Optionally, the mating member 71 is configured as a wear-resistant block. Figure 12 This is a schematic diagram of the structure of the mating component provided in an embodiment of the present invention, as shown below. Figure 12 As shown, the mating part 71 is provided with a lock hole 711. It is readily understood that the lock head 61, by inserting into the lock hole 711, prevents relative movement between the inner shell assembly 3 and the outer shell assembly 1, thereby achieving the locking function of the locking mechanism 6. Further, the pressing member 72 is movably disposed on the bracket 13 of the outer shell assembly 1 and is configured to pass through the lock hole 711 to trigger the unlocking of the locking mechanism 6. That is, the lock head 61 is inserted into the lock hole 711 from one side to lock, and the pressing member 72 is inserted into the lock hole 711 from the other side to push the lock head 61 out, thereby unlocking. Further still, the second reset member 73 is disposed on the bracket 13 of the outer shell assembly 1 and is configured to drive the pressing member 72 away from the mating part 71. Optionally, the second reset member 73 is configured as a spring or other elastic structure, driving the pressing member 72 to move by its own preload. That is, when the user presses the pressing member 72 to unlock, the second reset member 73 drives the pressing member 72 to reset by its preload. On the other hand, the second limiting member 74 is disposed on the bracket 13 of the housing assembly 1 and locks the pressing member 72 to prevent the pressing member 72 from being dislodged from the housing assembly 1. That is, the second limiting member 74 is used to prevent the pressing member 72 from being ejected from the bracket 13 by the second reset member 73. Optionally, the second limiting member 74 is configured as a U-shaped retaining spring.

[0042] like Figure 12 As shown, in one embodiment, the mating member 71 has a shallow groove 712 on one side of the lock hole 711. When the pressing member 72 pushes the end of the lock head 61 to the bottom of the shallow groove 712, the lock head 61 can be disengaged from the lock hole 711, thereby unlocking.

[0043] Figure 13 This is a schematic diagram of the structure of the bracket provided in an embodiment of the present invention, as shown below. Figure 13 As shown, in one embodiment, the bracket 13 of the outer casing assembly 1 is provided with a second mounting groove 131, a third mounting groove 132, a first perforation 133, a fourth mounting groove 134, and a second insertion hole 135. Specifically, the first perforation 133 connects the second mounting groove 131 and the third mounting groove 132, the fourth mounting groove 134 is formed at the bottom of the third mounting groove 132, and the second insertion hole 135 connects to the first perforation 133. Further, a mating member 71 is disposed in the second mounting groove 131, a second resetting member 73 is disposed in the fourth mounting groove 134, a pressing member 72 is disposed in the third mounting groove 132 and extends into the locking hole 711 through the first perforation 133, and a second limiting member 74 is inserted into the second insertion hole 135 and extends into the first perforation 133 to lock the pressing member 72. Optionally, two second reset members 73 are provided, and two corresponding fourth mounting slots 134 are provided and distributed on both sides of the first perforation 133, thereby making the reciprocating motion of the pressing member 72 smoother.

[0044] like Figure 12 As shown, in one embodiment, the mating member 71 extends from the edge of the locking hole 711 to form an extension portion 713. The extension portion 713 extends into the first slit hole 133 to enhance the installation strength of the mating member 71. Furthermore, the extension portion 713 is provided with a second clearance groove 7131. When the second limiting member 74 extends into the first slit hole 133 to lock the pressing member 72, it can pass through the second clearance groove 7131, thereby fixing the mating member 71 to the bracket 13 to prevent the mating member 71 from falling off. At the same time, it helps to improve the limiting effect of the second limiting member 74 on the pressing member 72.

[0045] like Figure 9 and Figure 13 As shown, in one embodiment, each of the two arms of the bracket 13 has a boss 136 at its end. The second mounting groove 131, the third mounting groove 132, the first perforation 133, the fourth mounting groove 134, and the second insertion hole 135 are all located at the boss 136. Further, the boss 136 is U-shaped, and a U-shaped mating groove 121 is correspondingly provided at the first end of the outer shell body 12. It is readily understood that when the bracket 13 is located inside the outer shell body 12, the boss 136 engages with the mating groove 121.

[0046] It is easy to understand that there are two locking mechanisms 6, symmetrically distributed on both sides of the inner shell assembly 3. Correspondingly, there are two unlocking mechanisms 7, symmetrically distributed on both sides of the outer shell assembly 1, with each unlocking mechanism 7 corresponding to one locking mechanism 6. Therefore, the storage compartment can only be opened by unlocking from both sides simultaneously, preventing the inner shell assembly 3 from being ejected due to accidental activation. Furthermore, even if the storage compartment falls, the unlocking mechanisms on both sides will not be triggered simultaneously, preventing items from being thrown out due to impact from the falling storage compartment, thus improving safety. On the other hand, users can also complete the unlocking operation with one hand, improving convenience.

[0047] Figure 14 This is a schematic diagram of the gear structure provided in an embodiment of the present invention, as shown below. Figure 14 As shown, in one embodiment, the gear 4 includes a gear body 41 and a connecting portion 42. Specifically, the gear body 41 is used to mesh with the rack 2. Further, the connecting portion 42 extends axially along the gear body 41 and is connected to a coil spring 5. Thus, the coil spring 5 can drive the gear 4 to rotate through the connecting portion 42, thereby causing the gear body 41 to roll along the rack 2, ultimately driving the inner shell assembly 3 to extend out of the outer shell assembly 1.

[0048] like Figure 14 As shown, in one embodiment, the connecting portion 42 is provided with a first slot 421. Further, the coil spring 5 is connected to the connecting portion 42 via the first slot 421. Specifically, the coil spring 5 can pass through the first slot 421 and be wound and fixed onto the connecting portion 42.

[0049] like Figure 6 and Figure 10 As shown, the inner shell assembly 3 also has a damper 8 on its inner shell accessory 33. Specifically, the damper 8 is connected to the gear 4 and is configured to provide constant resistance to the gear 4 as it rolls toward the first end of the outer shell assembly 1, allowing the inner shell assembly 3 to pop out at a uniform speed. This prevents the inner shell assembly 3 from shaking when it moves to the stop position, thus preventing damage to items in the storage slot 31 due to vibration. Furthermore, when the inner shell assembly 3 is retracted into the outer shell assembly 1, the inner shell assembly 3 will not collide with the outer shell assembly 1 to generate noise, thereby preventing any impact on the user's experience.

[0050] Figure 15 This is a schematic diagram of the damper provided in an embodiment of the present invention, as shown below. Figure 15 As shown, in one embodiment, the damper 8 includes a damper body 81 and a rotor 82. Specifically, the damper body 81 is fixed to the inner shell auxiliary member 33 of the inner shell assembly 3, and the rotor 82 is rotatably mounted on the damper body 81 and fixedly connected to the gear 4. It is readily understood that the rotor 82 and the gear 4 are coaxial and rotate synchronously.

[0051] like Figure 14As shown, in one embodiment, the gear body 41 of the gear 4 has a recess 411. Further, the rotor 82 extends into the recess 411 and is fixedly connected to the gear 4. It is readily understood that the rotor 82 has an elongated oval cross-section, and the shape of the recess 411 matches that of the rotor 82. Thus, when the gear 4 rotates, the rotor 82 will rotate synchronously under the drive of the gear 4.

[0052] Figure 16 This is a structural schematic diagram of the inner shell accessory provided in an embodiment of the present invention, as shown below. Figure 16 As shown, in one embodiment, the inner shell assembly 3 has a fifth mounting groove 331 on its inner shell accessory 33, and the bottom of the fifth mounting groove 331 has a second perforation 332. Further, the damper body 81 is fixed within the fifth mounting groove 331, and the rotor 82 passes through the second perforation 332 and extends into the recess 411 to be fixedly connected with the gear 4. Optionally, the damper body 81 is fixed within the fifth mounting groove 331 by adhesive.

[0053] like Figure 15 As shown, in one embodiment, the cylindrical damper body 81 has two symmetrically arranged protrusions 811 on its circumferential surface. Correspondingly, the inner wall of the fifth mounting groove 331 is recessed to form two symmetrically arranged limiting grooves 334. It is readily understood that when the damper body 81 is fixed in the fifth mounting groove 331, the protrusions 811 are confined within the limiting grooves 334 to prevent the damper body 81 from rotating.

[0054] Figure 17 This is a structural schematic diagram of the inner shell body from another perspective provided in an embodiment of the present invention, as shown below. Figure 17 As shown, in one embodiment, the inner shell body 32 of the inner shell assembly 3 is provided with a sixth mounting groove 323. Further, the coil spring 5 and the gear 4 are disposed within the sixth mounting groove 323.

[0055] like Figure 17 As shown, in one embodiment, a second slot 324 is formed on the sidewall of the sixth mounting slot 323. Further, the coil spring 5 extends into the second slot 324 to connect with the inner shell body 32 of the inner shell assembly 3.

[0056] Figure 18 This is a schematic diagram of the structure of the coil spring provided in an embodiment of the present invention, as shown below. Figure 18 As shown, the coil spring 5 includes a bent inner hook 51 and a bent outer hook 52. It is easy to understand that the inner hook 51 is connected to the connecting portion 42 via a first slot 421. On the other hand, the shape of the second slot 324 matches the outer hook 52, and the outer hook 52 extends into the second slot 324 to connect with the inner shell body 32.

[0057] like Figure 16As shown, in one embodiment, the inner shell component 33 of the inner shell assembly 3 is provided with a power-accumulating locking hole 333 that connects to the sixth mounting groove 323. It should be noted that after the gear 4 and the coil spring 5 are installed in place, the gear 4 is first moved to make the inner coil of the coil spring 5 coil and accumulate power. Then, a pin-shaped fixture is used to pass through the power-accumulating locking hole 333 and extend into the sixth mounting groove 323 to lock the gear 4, thereby maintaining the power-accumulating state of the coil spring 5. The pin-shaped fixture needs to be removed before the inner shell assembly 3 and the outer shell assembly 1 are assembled.

[0058] like Figure 17 As shown, in one embodiment, the inner shell body 32 of the inner shell assembly 3 is provided with a first clearance groove 325. Further, the gear 4 is exposed through the first clearance groove 325 so as to mesh with the rack 2.

[0059] like Figure 11 As shown, in one embodiment, the inner shell assembly 3 has a groove 326 on its inner shell body 32. Furthermore, the rack 2 moves relative to the inner shell assembly 3 via the groove 326. This results in a more compact storage compartment design, contributing to miniaturization. Exemplarily, two grooves 326 are provided and distributed on both sides of the inner shell body 32, which helps improve the smoothness of movement of the inner shell assembly 3.

[0060] Figure 19 This is a schematic diagram of the lock head provided in an embodiment of the present invention, as shown below. Figure 19 As shown, in one embodiment, the lock head 61 includes a first engaging portion 611, a locking portion 612, and a first positioning post 613. The locking portion 612 and the first positioning post 613 are respectively located at both ends of the first engaging portion 611. Further, the locking portion 612 is configured as a trapezoidal structure and has a slope 6121 facing the second end of the outer shell assembly 1, so that when the inner shell assembly 3 is retracted into the outer shell assembly 1, the lock head 61 slides into the lock hole 711 along the shallow groove 712 of the mating member 71. On the other hand, the first reset member 62 is sleeved on the first positioning post 613, which helps to improve the stability of the locking mechanism 6 during operation. Furthermore, two first grooves 6111 are symmetrically arranged on the first engaging portion 611, so that the first limiting member 63 can be inserted into the first grooves 6111 for limiting.

[0061] Figure 20 This is a schematic diagram of the pressing component provided in an embodiment of the present invention, as shown below. Figure 20As shown, in one embodiment, the pressing member 72 includes a pressing part 721, a second engaging part 722, and a second positioning post 723. The pressing part 721 is configured as an elongated cylindrical structure for user pressing to unlock. Further, the second engaging part 722 has two symmetrically arranged second grooves 7221 for the second limiting member 74 to be inserted into the second grooves 7221 for limiting. Simultaneously, the second engaging part 722 also serves to abut and push out the lock head 61 to achieve unlocking. On the other hand, there are two second positioning posts 723, symmetrically distributed on both sides of the second engaging part 722, to match with the second reset member 73. It is readily understood that the second reset member 73, sleeved on the second positioning post 723, helps improve the stability of the unlocking mechanism 7 during operation.

[0062] Figure 21 This is a schematic diagram of the structure of the second limiting member provided in an embodiment of the present invention, as shown below. Figure 21 As shown, in one embodiment, two hooks 741 are symmetrically provided at the two ends of the second limiting member 74 to improve the installation reliability of the second limiting member 74, thereby enabling the second limiting member 74 to continuously and stably limit the pressing member 72.

[0063] like Figures 7 to 9 As shown, in one embodiment, the bracket 13 of the outer shell assembly 1 is provided with a charging interface 9 for charging the storage compartment, thereby enabling the storage compartment to charge items (such as earphones) placed in the storage slot 31. Furthermore, the outer shell body 12 is provided with a charging hole 122 so that an external charging cable passes through the charging hole 122 and connects to the charging interface 9.

[0064] This invention provides a storage compartment, including an outer shell assembly and an inner shell assembly. The first end of the outer shell assembly has an opening forming a receiving cavity. A rack is disposed within the receiving cavity, extending from the first end to the second end of the outer shell assembly. The inner shell assembly has a storage slot and is movably disposed within the receiving cavity. A gear and a coil spring are disposed on the inner shell assembly. The gear meshes with the rack. The two ends of the coil spring are connected to the inner shell assembly and the gear, respectively, and are configured to drive the gear to roll along the rack toward the first end of the outer shell assembly, thereby causing the inner shell assembly to extend out of the receiving cavity. Thus, the storage compartment achieves the unlocking function through a purely mechanical structure by releasing preload through the coil spring to drive the gear to roll along the rack. This avoids the vibration problems associated with conventional cover opening and closing methods, and the gear and rack transmission structure effectively prevents malfunctions caused by drops or impacts.

[0065] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
