[0054] The preferred embodiments of the present application will be described in detail below with reference to the drawings.

[0055] Embodiment One

[0056] As shown in FIG. 1A, FIG. 1B and FIG. 2, the first embodiment of the present application provides a storage device, which comprises an inner container 100, a frame 200, a control rod 300, a control device 400 and a driving device. The inner container 100 defines a storage space 110, and the frame 200 defines a mounting space 210. The inner container 100 is mounted in the mounting space 210, and is in sliding connection with the frame 200. The inner container 100 can slide relative to the frame 200 between a closed position and an open position, passing through a first transition position and a second transition position in the process. When the inner container 100 is in the closed position, the inner container 100 is substantially completely located in the mounting space 210, and the storage space 110 of the inner container 100 is covered by the frame 200 to achieve concealment. When the inner container 100 is in the open position, part of the inner container 100 is located in the mounting space 210, and part of the inner container 100 is located outside the mounting space 210. The storage space 110 of the inner container 100 is exposed to facilitate use by the occupant. The control rod 300 is in sliding connection with the inner container 100 and the frame 200, and can slide relative to the inner container 100 and the frame 200 between a first position and a second position, passing through a third position and a fourth position in the process. In response to movement of the control rod 300 between the first position and the third position, the inner container 100 will move between the closed position and the first transition position. In response to movement of the inner container 100 between the second transition position and the open position, the control rod 300 will move between the fourth position and the second position. When the inner container 100 is in the closed position, the control rod 300 is in the first position. When the inner container 100 is in the first transition position, the control rod 300 is in the third position. When the inner container 100 is in the second transition position, the control rod 300 is in the fourth position. When the inner container 100 is in the open position, the control rod 300 is in the second position. The driving device comprises a motor 510 and a transmission mechanism 520. The motor 510 is connected with the transmission mechanism 520. The transmission mechanism 520 is separately and detachably connected with the inner container 100 and the control rod 300. When the control rod 300 is in any position between the first position and the third position except the third position, the transmission mechanism 520 is connected with the control rod 300 and is disconnected with the inner container 100. When the control rod 300 is in the third position, the transmission mechanism 520 is disconnected with the control rod 300. When the control rod 300 is in any position between the third position and the second position except the third position, the transmission mechanism 520 is connected with the inner container 100 and is disconnected with the control rod 300. When the control rod 300 is in the third position, the transmission mechanism 520 is in a critical connection state with the inner container 100 and the control rod 300. In this critical connection state, if the motor 510 rotates in a first direction, the rotation can be transmitted to the inner container 100 through the transmission mechanism 520 and drive the inner container 100 to move towards the open position. However, the rotation cannot be transmitted to the control rod 300 through the transmission mechanism 520, so the control rod 300 will remain stationary.Conversely, if the motor 510 rotates in the second direction, its rotation can be transmitted to the control rod 300 through the transmission mechanism 520, but its rotation cannot be transmitted to the inner bucket 100 through the transmission mechanism 520, so the motor 510 can drive the control rod 300 to move towards the first position, but cannot drive the inner bucket 100 to move. The control rod 300 is used to interact with the control device 400 to trigger the control device 400 to send different control signals at different positions, which are used to control the rotation of the motor 510. For example, when the control rod 300 is in the first position and the second position, the control rod 300 makes the control device 400 send a stop signal, which can be sent directly or indirectly by the control device 400 to the motor 510 to make the motor 510 stop rotating, that is, when the control rod 300 is in the first position and the second position, the motor 510 will stop rotating; when the control rod 300 moves from the first position to the third position, the control rod 300 makes the control device 400 send a first rotation signal to make the motor 510 rotate in the first direction, and the rotation of the motor 510 in the first direction will make the inner bucket 100 move in the opening direction (i.e. towards the open position); when the control rod 300 moves from the second position to the fourth position, the control device 400 will send a second rotation signal to make the motor 510 rotate in the second direction opposite to the first direction, and the rotation of the motor 510 in the second direction will make the inner bucket 100 move in the closing direction (i.e. towards the closed position). The control device 400 can be directly connected (e.g. electrically connected or communicatively connected) with the motor 510, so that the control device 400 can directly control the rotation of the motor 510, or the control device 400 can be first connected with the electronic control unit (ECU) of the vehicle, and the ECU is connected with the motor 510, so that the control device 400 can send different control signals to the ECU, and the ECU controls the motor 510 according to different control signals. The motor 510 can be a non-self-locking motor, so that when power is off, the opening and closing of the storage device can be driven manually.

[0057] The storage device can be driven to open and close by the motor 510, and the working process is as follows:

[0058] 1) Opening process

[0059] As shown in Fig. 3A, in the initial state (i.e. the closed state), the inner container 100 is in the closed position, and the control rod 300 is in the first position, at this time the control rod 300 will make the control device 400 send a stop signal, the passenger can control the motor 510 to rotate in the first direction through the external controller (for example, it can be the electronic control unit of the vehicle, not shown in the figure), the rotation is transmitted to the control rod 300 through the transmission mechanism 520, and the control rod 300 moves from the first position to the third position, when it moves to the third position, the inner container 100 will move from the closed position to the first transition position in response to the movement of the control rod 300, as shown in Fig. 3B, at the first transition position, the inner container 100 will open a small part and expose a part of the storage space 110, at the same time the control device 400 will send a first rotation signal, so the motor 510 will continue to rotate in the first direction, so the motor 510 will make the inner container 100 move to the open position through the transmission mechanism 520, and will pass through the second transition position in the process, in the process, the opening degree of the inner container 100 will gradually increase, in the process of the inner container 100 moving from the first transition position to the second transition position, the control rod 300 will remain stationary due to the rotation of the motor 510 in the first direction, and its position relative to the frame 200 will remain unchanged, because the inner container 100 moves relative to the control rod 300, the control rod 300 will switch (move) from the third position to the fourth position relative to the inner container 100; after the inner container 100 reaches the second transition position, it will continue to move to the open position, in the process of the inner container 100 moving from the second transition position to the open position, the inner container 100 will move together with the control rod 300 and make the control rod 300 move from the fourth position to the second position, when the inner container 100 moves to the open position, the control rod 300 will move to the second position, the control rod 300 will make the control device 400 send a stop signal to stop the rotation of the motor 510, the motor 510 will no longer drive the inner container 100 to move, so that the inner container 100 stops at the open position and exposes most of the storage space 110, as shown in Fig. 3C, thereby completing the opening of the storage device.

[0060] 2) Closing process

[0061] The passenger can control the motor 510 to rotate in the second direction opposite to the first direction through the external controller, so as to drive the inner bucket 100 to move from the open position to the first transition position, passing through the second transition position, when the inner bucket 100 moves from the open position to the second transition position, the control rod 300 will move from the second position to the fourth position, when the inner bucket 100 moves to the second transition position, the control rod 300 will move to the fourth position, so that the control device 400 sends a second rotation signal, and thus the motor 510 will continue to rotate in the second direction and drive the inner bucket 100 to move from the second transition position to the first transition position, in this process, the control rod 300 will remain stationary, and due to the movement of the inner bucket 100, the position of the control rod 300 will switch from the fourth position to the third position, when the inner bucket 100 moves to the first transition position, the control rod 300 will switch to the third position, and since the motor 510 rotates in the second direction at this time, the motor 510 will drive the control rod 300 to move from the third position to the first position, in this process, the inner bucket 100 will not be driven by the motor 510, but the inner bucket 100 will be driven by the control rod 300 to move from the first transition position to the closed position, when the control rod 300 moves to the first position, the control device 400 will send a stop signal to stop the rotation of the motor 510, and the control rod 300 and the inner bucket 100 will stop moving, so that the inner bucket 100 stops at the closed position, and the storage device is closed.

[0062] The storage device can also be manually driven to open and close (at this time, the passenger cannot control the motor 510 to open and close through the external controller, and the control device 400 cannot control the motor 510 to open and close), and the working process is as follows:

[0063] 1) Opening process

[0064] The passenger can manually apply a first external force to the transmission mechanism 520 of the storage device in the initial state, and the first external force is transmitted to the control rod 300 through the transmission mechanism 520, so that the control rod 300 moves from the first position to the third position, in this process, the control rod 300 drives the inner bucket 100 to move from the closed position to the first transition position, so that the inner bucket 100 is slightly opened, and then the passenger can apply a second external force to the inner bucket 100 to move from the first transition position to the closed position, and when moving to the closed position, the passenger can remove the second external force, and the inner bucket 100 stops at the closed position; when the inner bucket 100 moves from the first transition position to the closed position, the control rod 300 moves in the same way as in the electric drive mode, which will not be described here.

[0065] 2) Closing process

[0066] The passenger can exert a third external force on the inner container 100 in the closed state, which is opposite to the direction of the second external force. Under the action of the third external force, the inner container 100 moves from the closed position to the first transition position. In this process, the movement mode of the control rod 300 is the same as that in the electric drive mode, which will not be described here. When the inner container 100 moves to the first transition position, the control rod 300 is also located at the third position. Then the passenger can exert a fourth external force on the transmission mechanism 520, which is opposite to the direction of the first external force. The fourth external force is equivalent to the rotation of the motor 510 in the second direction, which can be transmitted to the control rod 300 through the transmission mechanism 520, so that the control rod 300 moves from the third position to the first position. In this process, the control rod 300 moves the inner container 100 from the first transition position to the closed position. Then the fourth external force is removed, and the closing of the storage device is completed.

[0067] The storage device can also be opened and closed by a combination of manual and electric drive (at this time the passenger cannot control the opening and closing of the motor 510 through the external controller, but the control device 400 can normally control the opening and closing of the motor 510). The working process is as follows:

[0068] 1) Opening process

[0069] The passenger can manually exert a first external force on the transmission mechanism 520 of the storage device in the initial state. The first external force is transmitted to the control rod 300 through the transmission mechanism 520, so that the control rod 300 moves from the first position to the third position. In this process, the control rod 300 moves the inner container 100 from the closed position to the first transition position, thereby slightly opening the inner container 100. At the same time, the control rod 300 makes the control device 400 send a first rotation signal, so that the motor 510 rotates in the first direction. The motor 510 drives the inner container 100 to move from the first transition position to the closed position, passing through the second transition position. When the inner container 100 moves from the second transition position to the closed position, the control rod 300 moves from the fourth position to the second position, and makes the control device 400 send a stop signal to stop the rotation of the motor 510, thereby completing the opening process. The process of driving the inner container 100 from the first transition position to the open position by the motor 510 is the same as that in the electric drive mode, and the specific description can be referred to the description in the electric drive mode.

[0070] 2) Closing process

[0071] The third external force can be applied by the occupant to the inner container 100 in the open state, so as to drive the inner container 100 to move from the closed position to the second transition position. After the inner container 100 moves to the second transition position, the third external force can be removed. During the process, the control rod 300 moves from the second position to the fourth position. After the control rod 300 moves to the fourth position, the control rod 300 drives the control device to send a second rotation signal, so as to drive the motor 510 to rotate in the second direction. Then, the motor 510 drives the inner container 100 to move from the second transition position to the first transition position. At the same time, the control rod 300 switches from the fourth position to the third position relative to the inner container 100. Then, the rotation of the motor 510 in the second direction drives the control rod 300 to move from the third position to the first position. The movement of the control rod 300 drives the inner container 100 to move from the first transition position to the closed position. After the control rod 300 reaches the first position, the control device 400 sends a stop signal to stop the rotation of the motor 510, and the control rod 300 stops moving, so as to realize the closing of the storage device. The process of driving the inner container 100 to move from the second transition position to the closed position by the motor 510 is the same as the electric driving mode, and the description in the electric driving mode can be referred to.

[0072] In some embodiments, the inner container 100 and the frame 200 can be provided with matching hard limit structures. The hard limit structures can be used to limit the opening position and the closed position of the inner container 100. That is, when the inner container 100 moves in the opening direction (i.e., the direction from the opening position to the closed position), the hard limit structures of the inner container 100 and the frame 200 can prevent the inner container 100 from continuing to move in the opening direction after the inner container 100 moves to the closed position. Similarly, when the inner container 100 moves in the closing direction opposite to the opening direction, the hard limit structures of the inner container 100 and the frame 200 can prevent the inner container 100 from continuing to move in the closing direction after the inner container 100 moves to the closed position.

[0073] In some embodiments, the inner container 100 can include an inner container body 120 and an outer cover plate 130, the storage space 110 is formed on (i.e. defined by) the inner container body 120, the inner container body 120 includes a face plate 121, two side plates 122, a back plate 123 and a bottom plate, each plate forms a drawer structure with an open upper end, the outer cover plate 130 is fixed on the face plate 121 and forms the outermost side of the inner container 100 (where the closer to the mounting space 210, the closer to the inside), for covering the face plate 121, so that the inner container 100 is more beautiful. When the inner container 100 is in the closed position, the outer cover plate 130 is substantially flush with the outer surface of the frame 200, so that the outer cover plate 130 and the frame 200 look like one, realize the hiding of the inner container 100, make the appearance of the storage device more beautiful. The outer cover plate 130 can be provided with a handle, so that the occupant can apply a pulling force to the inner container 100 through the handle to pull it out of the mounting space 210, the handle can be a hidden handle, for example, the outer cover plate 130 can extend beyond the bottom plate and the bottom of the frame 200, so that the occupant can pull the inner container 100 out through the protruding part of the outer cover plate 130, or the handle can be an exposed handle, for example, a U-shaped handle, to pull the inner container 100 out through the U-shaped handle.

[0074] In some embodiments, the inner container 100 and the frame 200 can be connected by at least one sliding rail structure, the sliding rail structure includes a guide rail 140 and a sliding block 220 (refer to FIG. 7A), the sliding block cooperates with the guide rail 140 and can slide along the guide rail 140, one of the guide rail 140 and the sliding block is fixed on the inner container 100, and the other is fixed on the frame 200. For example, there are two sliding rail structures, the guide rail 140 of the first sliding rail structure is fixed on one of the side plates 122, and the sliding block of the first sliding rail structure is fixed on the inner wall of the frame 200 opposite to the side plate 122, the guide rail 140 of the second sliding rail structure is fixed on the other side plate 122, and the sliding block of the second sliding rail structure is fixed on the inner wall of the frame 200 opposite to the side plate 122. The guide rail 140 can be fixed on the inner container 100 by screws 150.

[0075] In some embodiments, a screw plug plate 160 is further included, which is fixedly connected with the inner container 100, the guide rail 140 can be fixed on the inner container 100 by screws, and the screw plug plate 160 is used to cover the screws to avoid affecting the appearance of the inner container 100.

[0076] As shown in Fig. 4, in some embodiments, the control device 400 includes a housing 410, a tab 420 and a resilient member 430, the housing 410 is fixed on the frame 200 by a plurality of screws 440, the resilient member 430 is disposed in the housing 410, the tab 420 extends at least partially outside the housing 410 and is movable relative to the housing 410 between a first de-energized position (the right dashed line position) and a second de-energized position (the left dashed line position) via the energized position, the resilient member 430 is connected to the tab 420 and provides a resilient force to the tab 420, the resilient force keeps the tab 420 in the energized position, the control device 400 sends a stop signal when the tab 420 is in the first de-energized position and the second de-energized position, the control device 400 sends a first rotation signal when the tab 420 moves from the first de-energized position to the energized position, and the control device 400 sends a second rotation signal when the tab 420 moves from the second de-energized position to the energized position. The control lever 300 is detachably connected to the tab 420, when the control lever 300 is in the first position, the control lever 300 applies a force to the tab 420, the force overcomes the resilient force of the resilient member 430 and keeps the tab 420 in the first de-energized position, in response to the movement of the control lever 300 from the first position to the third position, the tab 420 moves from the first de-energized position to the energized position, when the control lever 300 moves to the third position, the tab 420 moves to the energized position, thereby the control device 400 sends the first rotation signal, when the control lever 300 moves between the third position and the fourth position, the relative position between the control lever 300 and the tab 420 remains unchanged, thus the tab 420 always keeps in the energized position, in response to the movement of the control lever 300 from the fourth position to the second position, the tab 420 moves from the energized position to the second de-energized position, when the control lever 300 moves to the second position, the tab 420 moves to the de-energized position, thereby the control device 400 sends the stop signal, conversely, when the control lever 300 moves from the second position to the fourth position, the tab 420 moves from the second de-energized position to the energized position, the control device 400 sends the second rotation signal, when the control lever 300 moves from the third position to the first position, the tab 420 moves from the energized position to the first de-energized position, thereby the control device 400 sends the stop signal.

[0077] As shown in FIGS. 5A-5D, the control lever 300 can include a lever body 310, the lever body 310 being provided with a first extension 320 and a second extension 330 extending outward (e.g., vertically outward), the first extension 320 and the second extension 330 being oppositely arranged, and the tab 420 being located between the first extension 320 and the second extension 330. As shown in FIG. 5A, when the control lever 300 is located at the first position, the first extension 320 abuts against the tab 420 and moves the tab 420 to the right to the first power-off position (the right dashed line position shown in FIG. 4), when the control lever 300 moves from the first position to the second position, the control lever 300 will move to the left, the first extension 320 gradually moves to the left, and the tab 420 moves to the power-on position under the elastic force of the elastic member 430; as shown in FIG. 5B, when the control lever 300 moves to the third position, the tab 420 is disengaged from the first extension 320 and the second extension 330 and remains at the power-on position (i.e., the solid line position shown in FIG. 4); as shown in FIG. 5C, when the control lever 300 moves relative to the inner pot 100 from the third position to the fourth position, the relative position of the control lever 300 and the tab 420 remains unchanged; as shown in FIG. 5D, when the control lever 300 moves from the fourth position to the second position, the second extension 330 will move to the left to abut against the tab 420 and move the tab 420 together, so as to move the tab 420 to the left to the second power-off position (the left dashed line position shown in FIG. 4). When the control lever 300 moves reversely (i.e., from the second position to the first position), the control lever 300 will move to the right, the second extension 330 will also move to the right, and the tab 420 will gradually move from the second power-off position to the power-on position under the elastic force, when the control lever 300 moves to the fourth position, the second extension 330 is disengaged from the tab 420, and the tab 420 returns to the power-on position, when the control lever 300 moves relative to the inner pot 100 from the fourth position to the third position, the control lever 300 remains stationary, and the tab 420 also remains stationary, when the control lever 300 moves from the third position to the first position, the first extension 320 will gradually approach the tab 420 and connect with the tab 420, so as to gradually move the tab 420 to the first power-off position, when the control lever 300 moves to the first position, the tab 420 moves to the first power-off position.

[0078] In some embodiments, the rod body 310 can be provided with a third extension 340 extending outwardly in a direction opposite to the first and second extensions, the third extension 340 being provided with a guide post 350, and the inner bucket 100 being provided with a guide groove 170, the guide post 350 being slidingly arranged in the guide groove 170 and being slidable along the guide groove 170, so that the control rod 300 is slidingly connected with the inner bucket 100. The guide groove 170 can include a first section 171, a second section 172 and a third section 173 connected in sequence, the second section 172 extending in the opening direction of the inner bucket 100, the first section 171 and the third section 173 extending in directions forming angles with the extending direction of the second section 172, and the first section 171 and the third section 173 extending towards different sides of the second section 172, for example, the first section 171 extending towards the right side of the second section 172, and the third section 173 extending towards the left side of the second section 172. When the control rod 300 is located at the first position, the guide post 350 is located at one end of the first section 171 away from the second section 172 (as shown in FIG. 5A), and the control rod 300 can be moved from the first position to the second position under the action of an external force or the driving of the motor 510, in the process, the guide post 350 moves in the first section 171 towards the connection between the first section 171 and the second section 172, and in the process, the guide post 350 causes the inner bucket 100 to move a small distance in the opening direction, so that when the guide post 350 moves to one end of the second section 172 adjacent to the first section 171 (as shown in FIG. 5B), the control rod 300 reaches the third position, and the inner bucket 100 moves from the closed position to the first transition position; then, under the action of an external force or the driving of the motor 510, the inner bucket 100 moves from the first transition position to the second transition position, and since the control rod 300 remains stationary, the guide post 350 moves relative to the inner bucket 100 from the connection between the second section 172 and the first section 171 to the connection between the second section 172 and the third section 173 (as shown in FIG. 5C), and the control rod 300 moves relative to the inner bucket 100 from the third position to the fourth position; then, the inner bucket 100 continues to move from the second transition position to the opening position, and causes the guide post 350 to move along the third section 173, thereby moving the control rod 300 leftwards and towards the second position, and when the guide post 350 moves to one end of the third section 173 away from the second section 172, the control rod 300 reaches the second position, and the above is the movement process of the guide post 350 in the guide groove 170 when the storage device is opened. When the storage device is closed, the movement process of the guide post 350 in the guide groove 170 is opposite to that when the storage device is opened, which will not be described here.

[0079] In some embodiments, the first section 171 and the second section 172 can be perpendicular to each other, so that when the control lever 300 is in the first position and the inner bucket 100 is in the closed position, the guide column 350 is in the first section 171 which is perpendicular to the opening direction, and the inner bucket 100 cannot move along the opening direction by the limiting of the guide column 350 and the first section 171, so as to limit the inner bucket 100 in the closed position, and at this time, there is no need to set a hard limiting structure for limiting the closed position on the inner bucket 100 and the frame 200. The third section 173 can be a zigzag structure (for example, a snake shape), so as to make the movement of the control lever 300 between the fourth position and the second position more stable. The transition between the first section 171 and the second section 172 and the transition between the second section 172 and the third section 173 can be smooth, so as to make the movement of the guide column 350 in them more smooth and avoid jamming.

[0080] In some embodiments, a long hole 312 can be formed on the lever body 310, a fastener (for example, a screw) passes through the long hole 312 and fixes the lever body 310 with the frame 200, and the fastener can move in the long hole 312 along the extension direction of the long hole 312, so that the control lever 300 can be installed on the frame 200 to prevent it from falling off, and the control lever 300 can move relative to the inner bucket 100 and the frame 200.

[0081] Referring to FIG. 2, in some embodiments, the transmission mechanism 520 is mounted on the frame 200, which can include a first pulley 521 connected to the motor 510, a belt 522 wound around the first pulley 521 and a second pulley 523 to form a belt transmission mechanism, a first gear 524 fixed on the second pulley 523, a second gear 525 engaged with the first gear 524, and a third gear 526 engaged with the second gear 525. A first rack 311 is provided on the rod body 310 of the control rod 300, and the first rack 311 is disengageably engaged with the second gear 525, so that the transmission mechanism 520 is disengageably connected to the control rod 300. A second rack 180 can be provided on the inner bucket 100, and the second rack 180 is disengageably engaged with the third gear 526, so that the transmission mechanism 520 is disengageably connected to the inner bucket 100. In this way, when the motor 510 rotates, it drives the first pulley 521 to rotate, which in turn drives the second pulley 523 and the first gear 524 to rotate. The rotation of the first gear 524 drives the second gear 525 to rotate, and the rotation of the second gear 525 drives the third gear 526 to rotate. When the second gear 525 is engaged with the first rack 311, the rotation of the second gear 525 drives the control rod 300 to move. When the third gear 526 is engaged with the second rack 180, the rotation of the third gear 526 drives the inner bucket 100 to move. The second rack 180 can extend in the opening direction to drive the inner bucket to move in the opening direction. The first pulley 521 can be formed on the motor 510, and the motor 510 is fixed on the frame 200.

[0082] In some embodiments, a first sub-gear 5251 can be provided on the second gear 525, and a second sub-gear 5261 can be provided on the third gear 526. The second gear 525 is engaged with the first gear 524, the first sub-gear 5251 is disengageably engaged with the first rack 311 to disengageably connect the transmission mechanism 520 to the control rod 300, the first sub-gear 5251 is also engaged with the third gear 526, and the second sub-gear 5261 is disengageably engaged with the second rack 180 to disengageably connect the transmission mechanism 520 to the inner bucket 100. The second gear 525 and the first sub-gear 5251 can be fixed on the same shaft so that the second gear 525 and the first sub-gear 5251 can rotate together. The third gear 526 and the second sub-gear 5261 can be fixed on the same shaft so that the third gear 526 and the second sub-gear 5261 can rotate together.

[0083] As shown in Fig. 6A, when the control rod 300 is in the first position, the first sub-gear 5251 is engaged with the first rack 311, and the second sub-gear 5261 is disengaged from the second rack 180. In response to an external force or the driving of the motor 510, the first sub-gear 5251 and the second sub-gear 5261 can rotate. The rotation of the first sub-gear 5251 will move the first rack 311, thereby moving the control rod 300 from the first position to the third position. When moving to the third position, the inner bucket 100 will move from the closed position to the first transition position. At the same time, as shown in Fig. 6B, the first sub-gear 5251 is disengaged from the first rack 311, and the second sub-gear 5261 is engaged with the second rack 180. Therefore, the control rod 300 will remain stationary, and the second rack 180 will move relative to the frame 200 and the control rod 300 under the driving of the second sub-gear 5251, thereby moving the inner bucket 100 from the first transition position to the closed position. When the inner bucket 100 moves to the closed position, the control rod 300 moves to the second position, and the second sub-gear 5261 is engaged with the lowermost end of the second rack 180, thereby achieving the opening of the storage device. When closing the storage device, the second sub-gear 5261 is always engaged with the second rack 180 during the movement of the inner bucket 100 from the closed position to the first transition position. When the inner bucket 100 moves to the first transition position, the control rod 300 is in the third position, and the first sub-gear 5251 can move the control rod 300 from the third position to the first position. The movement of the control rod 300 moves the inner bucket from the first transition position to the closed position, thereby disengaging the second sub-gear 5261 from the second rack 180.

[0084] As shown in Figs. 7A, 7B and 7C, the motor 510 can be fixed on the frame 200 by a screw 531. The frame 200 is provided with a first shaft 230, a second shaft 240 and a third shaft 250. The second pulley 523 and the first gear 524 are installed on the first shaft 230 by a screw 532 and can rotate around the first shaft 230. The second gear 525 and the first sub-gear 5251 are installed on the second shaft 240 by a screw 533 and can rotate around the second shaft 240. The third gear 526 and the second sub-gear 5261 are installed on the third shaft 250 by a screw 534 and can rotate around the third shaft 250.

[0085] The storage device of the embodiment one can be opened and closed by an electric mode or a manual mode, and has high flexibility. The transmission mechanism 520 includes a belt transmission mechanism, which can protect the motor 510 from overload and effectively prevent the damage of parts.

[0086] Embodiment two

[0087] As shown in FIGS. 8A, 8B, 8C and 8D, the second embodiment of the present application provides a storage device which is substantially the same as the storage device of the first embodiment, except that the control rod 300 and the control device 400 are different in structure and the way they interact. In the second embodiment, the control device 400 includes a first control device 450 and a second control device 460, both of which are fixed on the frame 200, and the control rod 300 interacts with the first control device 450 and the second control device 460 to make the first control device 450 and the second control device 460 send different control signals. Specifically, when the control rod 300 is in the first position, the control rod 300 makes the first control device 450 send a stop signal, when the control rod 300 moves from the first position to the third position, the first control device 450 sends a first rotation signal, when the control rod 300 is in the second position, the second control device 460 sends a stop signal, and when the control rod 300 moves from the second position to the fourth position, the second control device 460 sends a second rotation signal.

[0088] In some embodiments, similar to the control device 400 of the first embodiment, the first control device 450 can include a housing, a paddle and a spring, the paddle can move relative to the housing between an energized position and a de-energized position, and the spring applies an elastic force to the paddle, which keeps the paddle in the energized position. When the paddle is in the de-energized position, the first control device 450 sends a stop signal, and when the paddle moves from the de-energized position to the energized position, the first control device 450 sends a first rotation signal. The second control device 460 is the same as the first control device 450 in structure, and also includes a housing, a paddle and a spring. When the paddle of the second control device 460 is in the de-energized position, the second control device 460 sends a stop signal, and when the paddle moves from the de-energized position to the energized position, the second control device 460 sends a second rotation signal.

[0089] As shown in Fig. 8E, the control lever 300 of the second embodiment comprises a lever head 360 having a first side wall 361 and a second side wall 362, the lever head 360 is detachably connected with the toggle of the first control device 450 and the toggle of the second control device 460, when the control lever 300 is in the first position, the lever head 360 is disconnected with the toggle of the second control device 450, the first side wall 361 of the lever head 360 is in contact with the toggle of the first control device 450 and holds the toggle in the off position, the lever head 360 is away from the second control device 460, the toggle of the control device 460 is in the on position, as shown in Figs. 8A and 8B; when the control lever 300 moves from the first position to the third position, the toggle of the first control device 450 gradually moves to the on position, when the control lever 300 moves to the third position, the first side wall 361 is disconnected with the toggle of the first control device 450, the toggle returns to the on position; when the control lever 300 changes between the third position and the fourth position, the lever head 360 of the control lever 300 is disconnected with the first control device 450 and the second control device 460, thus the toggle of the first control device 450 and the toggle of the second control device 460 are both in the on position; when the control lever 300 moves from the fourth position to the second position, the second side wall 362 will be in contact with the toggle of the second control device 460 and move the toggle to the off position, when the control lever 300 moves to the second position, the toggle moves to the off position, as shown in Figs. 8C and 8D.

[0090] It can be understood that the toggle of the first control device 450 and the toggle of the second control device 460 can also be buttons, the same functions as described above can be achieved by moving the buttons between the off position and the on position.

[0091] The closing and opening process of the storage device of the second embodiment driven by the electric motor is as follows:

[0092] 1) Opening process: the control lever 300 is driven by the motor 510 to move from the first position to the third position, when moving to the third position, the toggle of the first control device 450 moves to the on position, the first control device 450 will send a first rotation signal, the inner bucket 100 moves to the first transition position, then the inner bucket 100 can move in the opening direction under the drive of the motor 510, when the inner bucket 100 moves to the second transition position, the control lever 300 will switch to the fourth position relative to the inner bucket 100, as the inner bucket 100 continues to move from the second transition position to the opening position, the second side wall 362 of the lever head 300 will be in contact with the toggle of the second control device 460 and move it to the off position, when the inner bucket 100 moves to the opening position, the toggle is in the off position, the motor 510 stops rotating, and the inner bucket 100 stops at the opening position.

[0093] 2) Closing process: the inner bucket 100 is driven by the motor 510 to move towards the closing direction, when it moves to the second transition position, the toggle of the second control device 460 returns to the energized position, the second control device 460 sends the second rotation signal, the motor 510 continues to drive the inner bucket 100 to move towards the closing direction, when it moves to the first transition position, the control rod 300 reaches the third position, the motor 510 drives the control rod 300 to move towards the first position, when it moves to the first position, the control rod 300 makes the inner bucket 100 move from the first transition position to the closing position, and makes the toggle of the first control device 450 move to the de-energized position, so that the first control device 450 sends the stop signal, the motor 510 stops rotating, thereby making the inner bucket 100 stop at the closing position.

[0094] The process of driving the opening and closing of the storage device by manual mode and manual+electric combined mode is similar to the first embodiment, and specific reference can be made to the description in the first embodiment, which will not be repeated here.

[0095] Embodiment Three

[0096] As shown in FIGS. 9A, 9B, 9C and 9D, the third embodiment of the present application provides a storage device, which is based on the second embodiment, and the positions of the first control device 450 and the second control device 460 are improved, and the movement mode of the control rod 300 and the structure of the guide groove 170 on the inner bucket 100 are also improved. In the third embodiment, the movement trajectories of the inner bucket 100 and the control rod 300 are also different from those in the first and second embodiments. At this time, the closing position, the opening position and the first transition position of the inner bucket 100 are the same as those in the first embodiment, and the first position, the third position and the second position of the control rod 300 are also the same as those in the first embodiment, the difference is that when the inner bucket 100 moves from the second transition position to the opening position, the control rod 300 will not move with the inner bucket 100, but will remain stationary. That is, when the control rod 300 is in the third position, the fourth position and the second position relative to the inner bucket 100 and any position between them, the relative position of the control rod 300 to the frame 200 does not change.

[0097] The installation position and function of the first control device 450 are the same as those in the second embodiment, and the second control device 460 is no longer installed on the frame 200, but is installed on the inner bucket 100. When the control rod 300 is in the first position, the control rod 300 makes the first control device 450 send the stop signal, when the control rod 300 moves from the first position to the third position, the first control device 450 can send the first rotation signal, when the control rod 300 is in the second position, the second control device 460 can send the stop signal, and when the control rod 300 moves from the second position to the fourth position, the second control device 460 can send the second rotation signal.

[0098] The first control device 450 and the second control device 460 have the same functions as the second embodiment. As shown in Fig. 9E, the lever 300 of the third embodiment has the same structure as the second embodiment, and the lever head 360 further comprises a third side wall 363. The first side wall 361 cooperates with the first control device 450 in the same way as the second embodiment, which will not be described here. The third side wall 363 is used to cooperate with the second control device 460. When the lever 300 is in a position other than the fourth position and the second position, the third side wall 363 is disengaged from the tab of the second control device 460, and the tab of the second control device 460 remains in the energized position. When the lever 300 moves from the fourth position to the second position, the third side wall 363 contacts the tab of the second control device 460 and moves the tab from the energized position to the de-energized position.

[0099] In the third embodiment, the first segment 171 and the second segment 172 of the guide slot 170 have the same structure as the first embodiment, and the third segment 173 has a different structure from the first embodiment. The third segment 173 is connected to the second segment 172 and extends in the same direction, i.e. in the opening direction, so that when the inner container 100 moves between the first transition position and the open position, the lever 300 remains stationary.

[0100] The opening and closing process of the storage device of the third embodiment is driven by an electric motor as follows:

[0101] 1) Opening process: The motor 510 drives the lever 300 to move from the first position to the third position, and at the same time, the inner container 100 moves from the closed position to the first transition position. The first control device 450 sends a first rotation signal, and the motor 510 drives the inner container 100 to move towards the open position. When it moves to the second transition position, the position of the lever 300 relative to the inner container 100 becomes the fourth position, and the second control device 460 is connected to the lever 300 (for example, the tab contacts the third wall 363 of the lever head 360). As the inner container 100 moves from the second transition position to the open position, the tab will move from the energized position to the de-energized position, and then the second control device 460 sends a stop signal to stop the motor 510 from rotating, so that the inner container 100 stops at the open position.
