[0045] Figures 1 to 5 The locking mechanism 10 in some embodiments of the present invention is shown, and the locking mechanism 10 is used to achieve the purpose of locking or unlocking during an activity.

[0046] like Figure 5 and Figure 6 As shown, the locking mechanism 10 includes a housing 1 and a locking assembly 2, and the locking assembly 2 is arranged on the housing 1. The housing 1 is used to install the locking assembly 2, and the locking assembly 2 is used to complete the locking and unlocking of the corresponding parts or structures during the activity.

[0047] It should be noted that the shell 1 can be configured to be correspondingly set on the components that need to be locked or released, the components that need to be locked can be set on the shell 1, and the shell 1 and the components that need to be locked can be integrally formed together, depending on the components that need to be locked or unlocked on the product.

[0048] like Figure 7 and Fig. 9 As shown, the housing 1 is provided with a locking position 11 and an unlocking position 12 .

[0049] It can be understood that the locking position 11 and the unlocking position 12 can be configured to be defined by corresponding limiting mechanisms, or can be configured to simply refer to two different positions relative to the housing 1. The shape of the housing 1 can be flexibly set, and different settings can be made according to the application field, the product to be applied, the use requirements or the use scenario.

[0050] like Figures 6 to 10As shown, the locking assembly 2 includes a motor 21, an eccentric wheel 22, a sliding lock core 23 and an elastic member 24. The motor 21 is arranged on the shell 1, and the motor 21 is driven and connected to the eccentric wheel 22. The sliding lock core 23 is slidably arranged on the shell 1. A movable matching position 2311 is provided on the sliding lock core 23, and at least a part of the eccentric wheel 22 is located in the movable matching position 2311. The elastic member 24 is arranged on the shell 1, and the elastic member 24 is driven and connected to the sliding lock core 23. The elastic member 24 is used to provide a force driving the sliding lock core 23 to slide on the shell 1, so that the eccentric wheel 22 slides and is held against the inner wall of the movable matching position 2311.

[0051] It can be understood that the motor 21 is used to output torque when powered on. The eccentric wheel 22 can rotate eccentrically under the drive of the motor 21. The sliding lock core 23 is used to complete locking or unlocking during the sliding process. The elastic member 24 is used to provide elastic force to the sliding lock core 23.

[0052] It should be noted that the elastic member 24 can be any component capable of providing elastic force in the related art, such as a spring, an elastic rubber member, a metal spring or other types of elastic elements.

[0053] like Figures 6 to 10 As shown, the eccentric wheel 22 is configured to be able to rotate under the drive of the motor 21, so that the eccentric wheel 22 drives the sliding lock core 23 to slide relative to the housing 1, and then the sliding lock core 23 slides to the locking position 11 to lock, or slides to the unlocking position 12 to unlock.

[0054] It can be understood that when the motor 21 drives the eccentric wheel 22 to rotate, the change in the profile of the eccentric wheel 22 will cause the position of the sliding lock core 23 that is always supported on it to change accordingly, that is, the sliding lock core 23 can slide along a predetermined trajectory relative to the housing 1 under the support of the eccentric wheel 22. When the sliding lock core 23 slides to the unlocking position 12, the sliding lock core 23 releases the lock of the predetermined component, and when the sliding lock core 23 slides to the locking position 11, the sliding lock core 23 will lock the predetermined component, thereby limiting or fixing the relative position of the component to be locked and the housing 1.

[0055] It should also be noted that the sliding lock core 23 and the housing 1 can be connected via a sliding connection structure commonly used in the relevant technology, for example, a groove rail structure, a slide rail structure or various structures capable of sliding guidance.

[0056] In addition to the above, it should be noted that the rotation mode of the eccentric wheel 22 can be configured to always rotate in the same direction, or to rotate back and forth. Of course, no matter which rotation mode is adopted, the eccentric wheel 23 can make the sliding lock core 23 slide along a predetermined track or direction to smoothly complete locking and unlocking.

[0057] like Figures 7 to 10 As shown, in some embodiments of the locking mechanism 10, the eccentric wheel 22 is provided with an eccentric column 2221 at a position deviating from the center of the circle, the eccentric column 2221 is inserted into the movable fitting position 2311, and the eccentric column 2221 is slidably supported on the inner wall of the movable fitting position 2311.

[0058] It can be understood that the central axis of the eccentric column 2221 in the length extension direction does not pass through the center of the eccentric wheel 22 . During the rotation process, the eccentric column 2221 will rotate around the center of the eccentric wheel 22 .

[0059] In actual operation, the eccentric column 2221 will contact the inner wall of the movable matching position 2311 through different positions under the drive of the eccentric wheel 22, and when the eccentric column 2221 supports the sliding lock core 23 through different positions, the sliding lock core 23 will slide to the corresponding position.

[0060] like Figures 7 to 10 As shown, in some embodiments of the locking mechanism 10 , a movable fitting groove 231 is provided on the sliding lock core 23 , the movable fitting groove 231 defines a movable fitting position 2311 , and the eccentric wheel 22 is movably inserted into the movable fitting groove 231 .

[0061] Understandably, under the action of the elastic member 24, the eccentric wheel 22 will always be held against the groove wall of the movable matching groove 231. In this way, during the rotation of the eccentric wheel 22, the sliding lock core 23 will slide on the housing 1 under the combined action of the elastic member 24 and the eccentric wheel 22.

[0062] It should be noted that the groove wall profile of the movable matching groove 231 can be flexibly set. Specifically, the groove wall profile can be set depending on whether the rotation mode of the eccentric wheel 22 is configured to be reciprocating rotation or always rotate in the same direction.

[0063] like Figures 7 to 10 As shown, in some embodiments of the locking mechanism 10, a limiting portion 232 is provided on the sliding lock core 23, a limiting channel 13 is provided on the shell 1, the limiting portion 232 is located in the limiting channel 13, and the limiting portion 232 is configured to be able to slide in the limiting channel 13 driven by the sliding lock core 23.

[0064] It can be understood that the limiting portion 232 will always slide along the limiting channel 13 driven by the sliding lock core 23. When the limiting portion 232 is held on the side wall at the end of the limiting channel 13, the sliding lock core 23 cannot continue to move in this direction, thereby avoiding excessive sliding of the sliding lock core 23, ensuring the smooth completion of locking and unlocking, and reducing the failure rate.

[0065] like Figure 8 and Fig.10As shown, in some embodiments of the locking mechanism 10 , a mounting post 233 is disposed on the sliding lock core 23 , the elastic member 24 is sleeved on the mounting post 233 , and the elastic member 24 is respectively supported on the sliding lock core 23 and the housing 1 .

[0066] It can be understood that the mounting post 233 is used to limit the position of the elastic member 24 to prevent the elastic member 24 from being held to other positions on the sliding lock core 23 , thereby ensuring that the elastic force of the elastic member 24 can always act on the sliding lock core 23 .

[0067] like Figures 6 to 10 As shown, in some embodiments of the locking mechanism 10 , the elastic member 24 is used to provide a force to drive the sliding lock cylinder 23 to slide to the locking position 11 .

[0068] It can be understood that in this embodiment, the elastic member 24 will always drive the sliding lock core 23 to slide toward the locking position 11, so that the sliding lock core 23 will always be held on the eccentric wheel 22 in this direction.

[0069] like Figure 6 As shown, in some embodiments of the locking mechanism 10, an indicator position 14 is provided on the shell 1; it can be understood that the user can directly observe and determine the current state of the locking component 2 through the indicator position 14, so that the user can quickly determine whether the product is currently in a locked state or an unlocked state.

[0070] The locking assembly 2 further includes an indication structure 25, which includes a first indication member 251 and a second indication member 252, and the first indication member 251 and the second indication member 252 are both disposed on the sliding lock cylinder 23 or the eccentric wheel 22;

[0071] Among them, the first indicator 251 and the second indicator 252 can move relative to the shell 1 driven by the sliding lock core 23 or the eccentric wheel 22. The first indicator 251 is configured to be able to align with the indicator position 14 when the sliding lock core 23 is in the locking position 11, and the second indicator 252 is configured to be able to align with the indicator position 14 when the sliding lock core 23 is in the unlocking position 12.

[0072] It can be understood that the first indicator 251 and the second indicator 252 are arranged one by one in sequence, so that the two can be aligned with the indication position one by one under the drive of the sliding lock core 23 or the eccentric wheel 22. The user can know which of the first indicator 251 and the second indicator 252 is currently aligned with the indication position by observing the position, and then check the current position of the sliding lock core 23, and finally determine whether the locking assembly 2 is currently in a locked state or an unlocked state.

[0073] It should be noted that the first indicator 251 and the second indicator 252 can be configured to have different colors, so that the user can determine the current state of the locking assembly 2 by observing different colors through the indicator position 14. The first indicator 251 and the second indicator 252 can be configured to have different patterns, so that the current state of the locking assembly 2 can be determined by different patterns. Of course, the first indicator 251 and the second indicator 252 can also be other structures in the prior art that can quickly distinguish the two.

[0074] It should also be noted that when the user observes the first indicator 251 through the indicator position 14, it can be directly determined that the sliding lock cylinder 23 is currently in the locked position 11; when the user observes the second indicator 252 through the indicator position 14, it can be directly determined that the sliding lock cylinder 23 is currently in the unlocked position 12. Of course, please refer to Figure 6 If the shell 1 is correspondingly set on a certain external component, and the first indicator 251 and the second indicator 252 are configured to be always exposed outside the shell 1, an indicator position 14 can be opened on the external component, so that the current position state of the locking assembly 2 can be observed and determined on the remaining components installed on the shell 1.

[0075] In some embodiments, the first indicator 251 and the second indicator 252 may be disposed on the eccentric wheel 22 , so that the first indicator 251 and the second indicator 252 rotate together under the drive of the eccentric wheel 22 .

[0076] In other embodiments, the first indicator member 251 and the second indicator member 252 may be disposed together on the sliding lock core 23 , so that the first indicator member 251 and the second indicator member 252 move together under the drive of the sliding lock core 23 .

[0077] Figures 1 to 4 The storage device 20 in some embodiments of the present invention is shown. The shape of the storage device 20 can be flexibly set. The storage device 20 includes a locking mechanism 10 and a locking mechanism 30.

[0078] like Figures 1 to 4 As shown, the locking mechanism 30 includes a base body 31 and a locking member 32. The shell 1 is arranged on the base body 31. A locking opening 311 is opened on the base body 31. The locking member 32 is slidably arranged on the base body 31. The locking member 32 is configured to be able to cover or open the locking opening 311 during the sliding process; when the locking member 32 is configured to cover the locking opening 311, the sliding lock core 23 can be slidably inserted, thereby fixing the relative position of the locking member 32 and the base body 31.

[0079] It can be understood that the seat 31 is used to install the housing 1 on the one hand, and is also used to be fixed on other components that need to be switched between locking and unlocking. After the locking member 32 covers the locking opening 311, if the sliding lock core 23 slides to the locking position 11, the locking member 32 cannot continue to slide on the seat 31, so that the locking member 32 always keeps covering the locking opening 311, thereby achieving the purpose of locking. When the locking member 32 covers the locking opening 311, if the sliding lock core 23 slides to the unlocking position 12, the locking member 32 can still slide on the seat 31, thereby opening the locking opening 311, thereby achieving the purpose of unlocking.

[0080] Furthermore, a locking groove 321 is formed on the locking member 32 , and the sliding lock core 23 is inserted into the locking groove 321 , so as to achieve the function of fixing the relative position of the locking member 32 and the housing 1 .

[0081] In some embodiments of the storage device 20 , the storage device 20 further includes a control mechanism, which includes a communication control circuit board and a conductive structure. The communication control circuit board is connected to a power source through the conductive structure, and the communication control circuit board is electrically connected to the motor 21 .

[0082] It can be understood that the control mechanism is used to control the motor 21 to perform a predetermined operation after receiving the corresponding command signal. The command signal can be configured to be issued by various components, devices, mechanisms or terminal products in the relevant technology.

[0083] Specifically, the communication control circuit board includes an NFC communication module, a Bluetooth communication module, a WI-FI communication module and / or a telephone communication module.

[0084] It can be understood that the setting of the NFC communication module will enable the product to have the NFC communication function, and the user can control the NFC communication module to connect through the NFC structural element. The setting of the Bluetooth communication module will enable the user to control the motor 21 through Bluetooth; the setting of the WI-FI communication module will enable the user to control the motor 21 through the network; the setting of the telephone communication module will enable the user to control the motor 21 through mobile phone text messages or mobile phone calls.

[0085] The implementation of this utility model has the following beneficial effects:

[0086] The utility model relates to a locking mechanism and a storage device, wherein the storage device comprises a locking mechanism. In the locking mechanism, an eccentric wheel is driven to rotate by a motor, and then the eccentric wheel drives a sliding lock core to slide on a housing, thereby driving the sliding lock core to slide to a locking position to achieve the purpose of locking, or driving the sliding lock core to slide to an unlocking position to achieve the purpose of unlocking. In this way, the tedious manual operation of the sliding lock core is eliminated, and the convenience of using the product is improved.

[0087] In addition, by setting the elastic part, the matching clearance between the movable matching position on the sliding lock core and the eccentric wheel is eliminated, that is, the matching virtual position of the sliding lock core in the sliding direction is eliminated, preventing the sliding lock core from locking failure or unlocking failure, and improving the durability of the product.

In the above embodiments, the description of each embodiment has its own emphasis. For parts that are not described in detail in a certain embodiment, please refer to the relevant description of other embodiments.

In addition, it can be understood that the steps in the method of the embodiment of the utility model can be adjusted in order, merged and deleted according to actual needs, and the modules in the device of the embodiment of the utility model can be merged, divided and deleted according to actual needs.
