Description

Technical Field

[0001] This utility model relates to the field of packaging technology, and in particular to a storage box. Background Technology

[0002] Bluetooth earphones need to be charged through an earphone case. Most existing earphone cases are flip-top type, which requires you to manually flip the lid up and down to open and close the earphone case. This method is inconvenient.

[0003] In response, a related technology provides an earphone case comprising an inner shell and an outer shell. A pivot is fixedly mounted on the outer shell, and the inner shell rotates relative to the outer shell around the pivot. The earphone case can be opened and closed laterally by manually rotating the inner shell relative to the outer shell, which is simple to operate. However, because the pivot is fixed, the opening angle of the inner shell is limited by the shape of the inner and outer shells, making it inconvenient to take out the earphones; in addition, the position of the inner shell cannot remain stable when it is closed.

The inner shell is movable relative to the outer shell. During the movement of the inner shell, the end of the inner shell rotates between a first position and a second position, the first position and the second position being located in the same direction. The locking mechanism is disposed on the outer shell. When the end of the inner shell is located in the first position, the locking mechanism is used to lock or unlock the relative position of the inner shell and the outer shell.

[0006] As a preferred technical solution for the storage box, the inner shell is provided with a positioning post, and the outer shell is provided with an arc-shaped groove; the positioning post and the arc-shaped groove are slidably engaged.

[0007] As a preferred technical solution for the storage box, the storage box further includes a drive mechanism disposed on the outer shell, the drive mechanism being pulsatorically connected to the locking mechanism; the drive mechanism is configured to provide power to the inner shell during the process of switching the end of the inner shell from the first position to the second position.

[0008] As a preferred technical solution for the storage box, the driving mechanism includes a slider slidably connected to the outer shell; the locking mechanism includes a locking pin slidably disposed on the outer shell, and a transmission component for driving the locking pin to slide relative to the outer shell; when the end of the inner shell is located in the first position, the transmission component drives the locking pin to insert into the slider.

[0009] As a preferred technical solution for the storage box, a first elastic element is provided between the slider and the outer shell. The first elastic element is configured to provide elastic force to the slider during the process of switching from the first position to the second position at the end of the inner shell, and cause the slider to push the positioning post to slide along the arc groove.

[0010] As a preferred technical solution for the storage box, the slider is provided with a first guide surface, which is used to guide the locking pin into the slider; or...

[0011] The locking pin is provided with a second guide surface, which is used to guide the locking pin into the slider.

[0012] As a preferred technical solution for the storage box, the transmission assembly includes a first connecting rod and a second connecting rod. The first connecting rod is slidably connected to the outer shell, and the first connecting rod is rotatably connected to the second connecting rod. The second connecting rod is rotatably connected to the locking pin, and the sliding direction of the first connecting rod relative to the outer shell is set at an angle to the sliding direction of the locking pin relative to the outer shell.

[0013] As a preferred technical solution for the storage box, the free end of the first connecting rod is provided with an operating member, and a second elastic member is provided between the operating member and the outer shell; when the end of the inner shell is located in the first position, the second elastic member is configured such that the operating member always has a tendency to drive the locking pin to insert into the slider through the transmission assembly.

[0014] As a preferred technical solution for the storage box, the outer shell has arc-shaped grooves on both opposite sides, and the inner shell has positioning posts on both opposite sides; the storage box includes two driving mechanisms, and the sliders of the two driving mechanisms are respectively configured to correspond one-to-one with the two positioning posts;

[0015] The locking mechanism includes two locking pins, and the transmission assembly includes two second connecting rods rotatably connected to each other. The two second connecting rods are rotatably connected to the two locking pins respectively. When the end of the inner shell is in the first position, the transmission assembly is used to simultaneously drive the two locking pins to insert into the two sliders respectively.

[0016] As a preferred technical solution for the storage box, the end is provided with an accommodating portion having an opening; the outer shell is at least provided with a covering surface that covers the accommodating portion.

[0017] The storage box provided by this utility model has at least the following beneficial effects:

[0018] This storage box includes an inner shell and an outer shell that houses the inner shell. The inner shell is movable relative to the outer shell. During the movement of the inner shell, its end rotates between a first position and a second position, both of which are in the same direction. When the inner shell needs to be opened, it rotates from the first position inside the outer shell to the second position outside, again in the same direction. That is, the inner shell rotates 180°, exposing its end, making it convenient for users to remove and put away items from the end. This convenient operation improves the user experience.

[0019] The storage box also includes a locking mechanism. When the end of the inner shell is in the first position, the relative position of the inner shell and the outer shell can be locked by the locking mechanism to ensure the stability of the inner shell. The locking mechanism is located on the outer shell and is easy to operate.

[0020] The storage box features a positioning post on the inner shell and an arc-shaped groove on the outer shell. The positioning post and the arc-shaped groove slide together. When the inner shell rotates relative to the outer shell, the inner shell and the positioning post move synchronously along the arc-shaped groove. On the one hand, the movement of the inner shell along the arc-shaped trajectory of the arc-shaped groove allows the inner shell to open at a suitable angle, making it easy for users to take out and put in the Bluetooth earphones stored in the inner shell. On the other hand, it allows the inner shell to be displaced relative to the outer shell, avoiding the shape of the inner shell and the outer shell from affecting the opening angle of the inner shell.

[0021] The storage box also includes a drive mechanism. During the process of switching the end of the inner shell from the first position to the second position, the drive mechanism provides power so that the end of the inner shell can automatically switch from the first position to the second position without the need for manual operation by the user, which further improves the user experience.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0039] The headphone case in the related technology includes an inner shell and an outer shell. A pivot is fixedly installed on the outer shell, and the inner shell rotates around the pivot relative to the outer shell. The headphone case can be opened and closed laterally by manually rotating the inner shell relative to the outer shell, which is simple to operate. However, because the pivot is fixed, the opening angle of the inner shell is limited by the shape of the inner shell and the outer shell, making it inconvenient to take out the headphones; in addition, the position of the inner shell cannot remain stable when it is closed.

[0040] To address this issue, this embodiment provides a storage box for storing items. Specifically, in this embodiment, the storage box is an earphone case, and the item is a Bluetooth earphone. In other embodiments, depending on actual needs, the storage box can also be an eyeglass case, and the item can be eyeglasses, etc.

[0041] Please refer to Figures 1 to 5The storage box includes a locking mechanism 1, an inner shell 2, and an outer shell 3 that houses the inner shell 2. The inner shell 2 is movable relative to the outer shell 3. During the movement of the inner shell 2, its end 22 rotates between a first position and a second position, both located in the same direction. The locking mechanism 1 is disposed on the outer shell 3, and when the end 22 of the inner shell 2 is in the first position, the locking mechanism 1 is used to lock or unlock the relative position of the inner shell 2 and the outer shell 3. The inner shell 2 is used to store a Bluetooth headset 5. When the end 22 of the inner shell 2 is in the first position, the end 22 of the inner shell 2 is inside the outer shell 3; when the end 22 of the inner shell 2 is in the second position, the end 22 of the inner shell 2 moves to the outside of the outer shell 3. When the user needs to take out or put in the Bluetooth headset 5, the end 22 of the inner shell 2 moves from the first position inside the outer shell 3 to the second position outside the outer shell 3. Since the first position and the second position are in the same direction, that is, the inner shell 2 is rotated 180°, which makes it convenient for the user to take out the Bluetooth headset 5 from the end 22 of the inner shell 2 or put the Bluetooth headset 5 into the inner shell 2. The operation is convenient and improves the user experience. In addition, when the end 22 of the inner shell 2 is in the first position, the relative position of the inner shell 2 and the outer shell 3 is locked by the locking mechanism 1, which can ensure the stability of the position of the inner shell 2 after it is closed. The locking mechanism 1 is set on the outer shell 3, which is convenient to operate.

[0042] Alternatively, please refer to Figures 1 to 5 In this embodiment, the outer shell 3 is U-shaped. Specifically, the outer shell 3 includes a top plate 31 and two parallel and spaced-apart side plates 32. The top plate 31 is connected between the two side plates 32, and the locking mechanism 1 is disposed on the top plate 31. This arrangement further improves the convenience of operation. Specifically, the top plate 31 and the two side plates 32 together form an accommodating space and an opening communicating with the accommodating space. The opening is U-shaped. When the end 22 of the inner shell 2 is in the first position, the inner shell 2 is located in the accommodating space, and the end 22 is opposite to the top plate 31, so that the Bluetooth headset 5 is protected by the outer shell 3 and the inner shell 2. When the end 22 of the inner shell 2 is in the second position, the end 22 extends out of the opening and is located outside the outer shell 3, and the Bluetooth headset 5 is exposed, so that the user can easily take out and put away the Bluetooth headset 5. When it is necessary to switch the end 22 of the inner shell 2 from the first position to the second position, only the locking mechanism 1 on the top plate 31 needs to be operated, which is convenient.

[0043] Alternatively, please refer to Figures 1 to 5 In this embodiment, the inner shell 2 is rectangular.

[0044] In other embodiments, the shapes of the inner shell 2 and the outer shell 3 can be set according to actual needs.

[0045] Alternatively, please refer to Figure 4 and Figure 5The inner shell 2 has an end portion 22 with an opening, and the outer shell 3 has at least a covering surface 311 covering the covering portion 23. Specifically, in this embodiment, the covering surface 311 is the end face of the top plate 31 facing the end portion 22 in the first position. With this configuration, when the end portion 22 of the inner shell 2 is in the first position, the covering surface 311 of the outer shell 3 covers the covering portion 23 to protect the Bluetooth headset 5 located in the inner shell 2; when the inner shell 2 is in the second position, the opening of the end portion 22 switches to the outside of the outer shell 3, facilitating the insertion of the Bluetooth headset 5 into the covering portion 23 or the removal of the Bluetooth headset 5 from the covering portion 23. In this embodiment, the covering portion 23 is specifically a groove. Preferably, the shape of the covering portion 23 is similar to that of the Bluetooth headset 5 to improve the restraint effect on the Bluetooth headset 5.

[0046] Alternatively, please refer to Figure 2 and Figure 3 The inner shell 2 is provided with a positioning post 21, and the outer shell 3 is provided with an arc-shaped groove 321; the positioning post 21 and the arc-shaped groove 321 are slidably engaged. Specifically, the arc-shaped groove 321 is provided on the side plate 32. With this arrangement, the positioning post 21 can move along the extension direction of the arc-shaped groove 321. When the inner shell 2 is in the first position, the positioning post 21 abuts against one end of the arc-shaped groove 321; when the inner shell 2 is in the second position, the positioning post 21 abuts against the other end of the arc-shaped groove 321. During the process of the end 22 of the inner shell 2 moving from the first position to the second position, the inner shell 2 rotates relative to the outer shell 3 by an angle α, where α is the opening angle of the inner shell 2 relative to the outer shell 3. When the inner shell 2 needs to be opened, by rotating the inner shell 2, the inner shell 2 and the positioning post 21 move synchronously along the arc-shaped groove 321. On the one hand, the inner shell 2 moves along the arc-shaped trajectory of the arc-shaped groove 321, so that the inner shell 2 opens at an angle that is convenient for the user to take out and put away the Bluetooth headset 5; on the other hand, it allows the inner shell 2 to be displaced relative to the outer shell 3, avoiding the shape of the inner shell 2 and the outer shell 3 from affecting the opening angle α of the inner shell 2, thereby allowing the opening angle α of the inner shell 2 to be relatively larger. In this embodiment, the value of α is set to 180°. In other embodiments, the value of α can also be set according to actual needs.

[0047] Alternatively, please refer to Figure 2 In this embodiment, the arc-shaped groove 321 is arc-shaped, and α is the central angle corresponding to the arc-shaped groove 321. In other embodiments, the shape of the arc-shaped groove 321 can also be set to an elliptical arc or other shapes as needed.

[0048] Alternatively, please refer to Figure 2 and Figure 3The positioning post 21 is roughly racetrack-shaped to facilitate smoother movement along the arc-shaped groove 321, thereby improving the reliability of the movement of the end 22 of the inner shell 2 between the first and second positions. Specifically, the width of the positioning post 21 is matched with the width of the arc-shaped groove 321, and the length of the positioning post 21 is greater than the width of the arc-shaped groove 321. This prevents the inner shell 2 from rotating when the positioning post 21 slides along the arc-shaped groove 321, further enhancing the reliability of the movement of the inner shell 2 between the first and second positions.

[0049] Alternatively, please refer to 2 and Figure 3 The storage box also includes a drive mechanism 4 disposed on the outer shell 3. The drive mechanism 4 is pulsatorically connected to the locking mechanism 1. The drive mechanism 4 is configured to provide power to the inner shell 2 during the process of switching the end 22 of the inner shell 2 from the first position to the second position. With this configuration, the end 22 of the inner shell 2 can automatically switch from the first position to the second position by being powered by the drive mechanism 4, without the need for manual operation by the user, further improving the user experience.

[0050] Alternatively, please refer to Figure 2 and Figure 3 ,as well as Figure 6 and Figure 7 The driving mechanism 4 includes a slider 42 slidably connected to the outer shell 3; the locking mechanism 1 includes a locking pin 11 slidably disposed on the outer shell 3, and a transmission component 12 for driving the locking pin 11 to slide relative to the outer shell 3; when the end 22 of the inner shell 2 is in the first position, the transmission component 12 drives the locking pin 11 to insert into the slider 42. Specifically, in this embodiment, the slider 42 and the side plate 32 are slidably engaged, the side plate 32 is provided with a guide groove 323, the slider 42 is slidably disposed in the guide groove 323, and the slider 42 is also provided with a locking hole 422. When the end 22 of the inner shell 2 is in the first position, the locking pin 11 is inserted into the locking hole 422. With this configuration, when the end 22 of the inner shell 2 is in the first position, the relative position of the slider 42 and the outer shell 3 can be locked by the locking pin 11 and the slider 42 engaging, thereby stabilizing the end 22 of the inner shell 2 in the first position and ensuring the relative position stability of the inner shell 2 and the outer shell 3. When the locking pin 11 separates from the locking hole 422, the inner shell 2 can automatically open outward relative to the outer shell 3 under the drive of the drive mechanism 4, ultimately stabilizing the end 22 of the inner shell 2 in the second position. In addition, since the slider 42 and the outer shell 3 slide together, the movement direction of the slider 42 can be stabilized, thereby ensuring that the inner shell 2 remains stable during the movement relative to the outer shell 3.

[0051] Alternatively, please refer to 2 and Figure 3A first elastic element 41 is provided between the slider 42 and the outer shell 3. The first elastic element 41 is configured to provide elastic force to the slider 42 during the process of the end 22 of the inner shell 2 switching from the first position to the second position, so that the slider 42 pushes the positioning post 21 to slide along the arc groove 321. Specifically, the positioning post 21 is always located on the moving path of the slider 42, and the slider 42 can abut against the positioning post 21. When the end 22 of the inner shell 2 switches from the first position to the second position, under the drive of the elastic force of the first elastic element 41, the slider 42 moves linearly relative to the outer shell 3, and the slider 42 pushes the positioning post 21 to move in an arc along the arc groove 321, realizing the conversion of linear motion into arc motion, so that the end 22 of the inner shell 2 automatically moves from the first position to the second position, which is simple in structure. In addition, when the end 22 of the inner shell 2 is in the second position, under the action of the elastic force of the first elastic element 41, the slider 42 can press the positioning post 21 against the side wall of the arc groove 321, keep the position of the positioning post 21 stable, and thus ensure the position of the inner shell 2 is stable, so that the inner shell 2 is stably kept in the open position.

[0052] Optionally, in this embodiment, the first elastic element 41 is a compression spring; in other embodiments, the first elastic element 41 may also be a tension spring, etc.

[0053] It should be noted that the movement of the inner shell 2 from the second position to the first position can be achieved by manually rotating the inner shell 2. Specifically, during the switching process of the end 22 of the inner shell 2 from the second position to the first position, the positioning post 21 pushes the slider 42 to move relative to the outer shell 3, and the first elastic element 41 is compressed. Of course, in other embodiments, it can also be achieved with other structures according to actual needs, and this embodiment is not limited to this.

[0054] Alternatively, please refer to Figure 2 and Figure 3 The slider 42 is provided with a first spring seat 421, and the side plate 32 is provided with a second spring seat 322. The two ends of the first elastic member 41 are respectively sleeved on the first spring seat 421 and the second spring seat 322. With this configuration, the deformation direction of the first elastic member 41 can be kept stable during deformation.

[0055] Alternatively, please refer to Figure 2 and Figure 3 The driving mechanism 4 includes a plurality of first elastic elements 41, which are evenly spaced along the length of the slider 42. Each of the first elastic elements 41 is connected between the outer shell 3 and the slider 42. By driving the slider 42 relative to the outer shell 3 through the plurality of first elastic elements 41, the force on the slider 42 can be ensured to be uniform. In this embodiment, an example is provided where the driving mechanism 4 includes two first elastic elements 41.

[0056] As one alternative, the driving component includes a motor mounted on the side plate 32, a nut connected to the motor drive, a screw threaded to the nut, and a push block rotatably connected to the screw thread. When the motor drives the nut to rotate, the screw thread causes the push block to slide relative to the outer shell 3, thereby causing the push block to drive the positioning post 21 to move along the arc groove 321. This also allows the end 22 of the inner shell 2 to switch between a first position and a second position.

[0057] Optionally, the slider 42 is provided with a first magnetic element (not shown in the figure), and the positioning post 21 is provided with a second magnetic element (not shown in the figure). The first and second magnetic elements are magnetically attracted to each other. Thus, when the locking pin 11 and the locking hole 422 are engaged, the slider 42 also locks the position of the positioning post 21, further improving the stability of the relative position between the inner shell 2 and the outer shell 3.

[0058] Alternatively, please refer to Figures 3 to 7 The transmission assembly 12 includes a first connecting rod 121 and a second connecting rod 122. The first connecting rod 121 is slidably connected to the outer casing 3, and the first connecting rod 121 and the second connecting rod 122 are rotatably connected. The second connecting rod 122 is rotatably connected to the locking pin 11, and the sliding direction of the first connecting rod 121 relative to the outer casing 3 forms an angle with the sliding direction of the locking pin 11 relative to the outer casing 3. Specifically, in this embodiment, the first connecting rod 121 is slidably connected to the top plate 31. With this configuration, when the first connecting rod 121 slides relative to the top plate 31, it will drive the second connecting rod 122 to rotate synchronously, thereby driving the locking pin 11 to slide relative to the top plate 31, so as to realize the insertion or separation of the locking pin 11 and the slider 42, which is simple in structure. Specifically, the first link 121 can slide relative to the outer shell 3 to have an unlocked position and a locked position. When the end 22 of the inner shell 2 is in the first position, when the first link 121 is in the unlocked position, the locking pin 11 is separated from the slider 42. When the first link 121 is in the locked position, the locking pin 11 is engaged with the slider 42.

[0059] Specifically, in this embodiment, the sliding direction of the first connecting rod 121 relative to the outer shell 3 is consistent with the sliding direction of the slider 42 relative to the outer shell 3, and both are the first direction (e.g., Figure 4 The direction indicated by the middle arrow ab), the sliding direction of the locking pin 11 relative to the outer casing 3 is the second direction (as shown by the middle arrow ab). Figure 4 (In the direction indicated by the middle arrow cd), the second direction is perpendicular to the first direction. The locking pin 11 can be inserted and engaged with the slider 42 along the second direction, thereby locking or unlocking the relative position of the slider 42 and the outer shell 3.

[0060] Alternatively, please refer to Figure 4 and Figure 5The top plate 31 is provided with a first sliding groove 312 and a second sliding groove 313. The first sliding groove 312 extends along a second direction, and the second sliding groove 313 extends along a first direction. The locking pin 11 slides within the first sliding groove 312, and the first connecting rod 121 slides within the second sliding groove 313 to ensure that the sliding direction of the locking pin 11 and the first connecting rod 121 relative to the top plate 31 is stable.

[0061] Alternatively, please refer to Figure 4 and Figure 5 The top plate 31 is also provided with a clearance groove 314 that is connected to the first slide groove 312 and the second slide groove 313 respectively. When the first connecting rod 121 slides relative to the top plate 31, the second connecting rod 122 moves in the clearance groove 314.

[0062] Optionally, the top plate 31 includes a top plate body 315 and a top cover plate 316 connected to the top plate body 315. The top plate body 315 is connected between two side plates 32, and the top cover plate 316 is fastened to the top plate body 315. A first sliding groove 312 is provided on the top plate body 315, and a second sliding groove 313 is provided on the top cover plate 316. The top plate body 315 and the top plate 31 together form a clearance groove 314.

[0063] Alternatively, please refer to Figure 4 and Figure 5 When the first link 121 is in the unlocked position, the second link 122 abuts against the groove wall on one side of the clearance groove 314. When the first link 121 is in the locked position, the second link 122 abuts against the groove wall on the other side of the clearance groove 314. This restricts the range of movement of the second link 122 in the clearance groove 314, thereby restricting the sliding range of the locking pin 11 relative to the top plate 31 and the sliding range of the first link 121 relative to the top plate 31, ensuring that the locking pin 11 can maintain a stable position when it is inserted into and separated from the lock hole 422.

[0064] Alternatively, please refer to Figure 3 The transmission assembly 12 also includes a torsion spring 124 and a rotating shaft 123. The second connecting rod 122 and the locking pin 11 are rotatably connected via the rotating shaft 123. The torsion spring 124 is sleeved on the rotating shaft 123, and the two torsion arms of the torsion spring 124 are respectively connected to the second connecting rod 122 and the locking pin 11. When the end 22 of the inner shell 2 is in the first position, the torsion spring 124 is configured to ensure that the locking pin 11 always has a tendency to insert into the slider 42. With this configuration, when the locking pin 11 is inserted into the slider 42, the position of the locking pin 11 can be kept stable under the torque drive of the torsion spring 124, thereby ensuring the stability of locking the relative position of the slider 42 and the outer shell 3. It can be understood that under the drive of the torsion spring 124, the second connecting rod 122 also drives the first connecting rod 121 to move towards the locking position, and keeps the first connecting rod 121 in the locked position.

[0065] Alternatively, please refer to Figures 3 to 5 The slider 42 is provided with a first guide surface 423, which is used to guide the locking pin 11 into the slider 42. This arrangement facilitates the automatic insertion of the locking pin 11 into the lock hole 422 when the inner shell 2 is closed, ensuring the reliability of the engagement between the locking pin 11 and the lock hole 422. Specifically, when the inner shell 2 is closed, the first guide surface 423 contacts the locking pin 11 and drives the locking pin 11 to retract into the top plate 31. The locking pin 11 compresses the torsion spring 124. When the locking pin 11 is aligned with the lock hole 422, it automatically inserts into the slider 42 under the drive of the torsion spring 124.

[0066] Alternatively, please refer to Figures 3 to 5 The locking pin 11 is provided with a second guide surface 111, which is used to guide the locking pin 11 into the slider 42. This configuration can further improve the reliability of the locking pin 11 automatically inserting into the slider 42.

[0067] Alternatively, please refer to Figures 3 to 5 An operating member 13 is provided at the free end of the first connecting rod 121, and a second elastic member 14 is provided between the operating member 13 and the outer shell 3. When the end 22 of the inner shell 2 is in the first position, the second elastic member 14 is configured such that the operating member 13 always has a tendency to drive the locking pin 11 to insert into the slider 42 through the transmission assembly 12. With this configuration, the user only needs to press the operating member 13 by hand to drive the first connecting rod 121 to the unlock position, thereby separating the locking pin 11 from the lock hole 422, which is convenient to operate. Furthermore, when the end 22 of the inner shell 2 is in the first position, under the drive of the second elastic member 14, the operating member 13 has a tendency to drive the first connecting rod 121 to the locked position, which also makes the locking pin 11 have a tendency to insert into the slider 42. Thus, the second elastic member 14 can cooperate with the torsion spring 124 to further improve the stability of the insertion and engagement of the locking pin 11 and the slider 42, thereby improving the stability of locking the relative position of the slider 42 and the outer shell 3.

[0068] Optionally, the second elastic element 14 is a compression spring. In other embodiments, the second elastic element 14 may also be configured as a tension spring or the like, as needed.

[0069] Alternatively, please refer to Figure 3 The outer shell 3 has arc-shaped grooves 321 on both opposite sides, and the inner shell 2 has positioning posts 21 on both opposite sides. Specifically, the two arc-shaped grooves 321 are respectively located on the two side plates 32. With this arrangement, the two positioning posts 21 are inserted into the two arc-shaped grooves 321 in a one-to-one correspondence. When the inner shell 2 moves relative to the outer shell 3, the two positioning posts 21 slide in the corresponding arc-shaped grooves 321, which can effectively improve the stability of the movement of the inner shell 2.

[0070] Alternatively, please refer to Figures 3 to 5In this embodiment, the storage box includes two driving mechanisms 4, with the sliders 42 of the two driving mechanisms 4 corresponding one-to-one with the two positioning posts 21; the locking mechanism 1 includes two locking pins 11, and the transmission assembly 12 includes two second connecting rods 122 rotatably connected to each other, with the two second connecting rods 122 rotatably connected to the two locking pins 11 respectively. When the end 22 of the inner shell 2 is in the first position, the transmission assembly 12 is used to simultaneously drive the two locking pins 11 to insert into the two sliders 42 respectively. With this configuration, the transmission assembly 12 can simultaneously drive the two locking pins 11 to move, thereby realizing that the two locking pins 11 can simultaneously engage with the two locking holes 422, so as to further improve the stability of locking the relative position of the sliders 42 and the outer shell 3. Specifically, the transmission assembly 12 includes two rotating shafts 123, two second connecting rods 122 and two locking pins 11 are rotatably connected to each other through the two rotating shafts 123, and the first connecting rod 121 is rotatably connected to both second connecting rods 122. Each rotating shaft 123 is fitted with a torsion spring 124, and the number of torsion springs 124 fitted on the rotating shaft 123 can be set according to actual needs.

[0071] Alternatively, please refer to Figure 2 Each side panel 32 is provided with a receiving groove 324. The outer shell 3 also includes two side cover plates 33. Two drive mechanisms 4 are respectively disposed in the two receiving grooves 324. The two side cover plates 33 respectively close the two receiving grooves 324 to improve the aesthetics of the storage box.
