[0109] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the present application.

[0110] According to a first aspect of the present application, referring to Figures 1 to 8 The present application provides a locking device 100, comprising a base 110, a locking assembly 120, an operating assembly 130 and a retaining assembly 140.

[0111] The base 110 is configured to be detachably connected with the to-be-locked component 12, that is, the base 110 is configured to be connected with the to-be-locked component 12. In a specific application scenario, the base 110 is integrated in a device such as a server 11, that is, the to-be-locked component 12 can be detachably mounted on the device through the base 110.

[0112] The locking assembly 120 is integrated in the base 110 and has a locked state and an unlocked state. When the locking assembly 120 is in the locked state, the base 110 and the to-be-locked component 12 are locked. Specifically, when the locking assembly 120 is in the locked state, the to-be-locked component 12 can be prevented from being separated from the base 110, that is, after the to-be-locked component 12 is mounted on the base 110, the locking assembly 120 in the locked state blocks the path through which the to-be-locked component 12 is separated from the base 110, or applies a force to the to-be-locked component 12 to prevent it from being separated from the base 110, so that the to-be-locked component 12 can be kept on the base 110.

[0113] When the locking assembly 120 is in the unlocked state, the base 110 and the to-be-locked component 12 are unlocked. It should be noted that the unlocking of the base 110 and the to-be-locked component 12 mentioned in the present application means that the to-be-locked component 12 can be separated from the base 110, and does not emphasize that the base 110 and the to-be-locked component 12 have been separated. Therefore, when the locking assembly 120 is in the unlocked state, the space position of the locking assembly 120 can avoid the to-be-locked component 12 so that it can be separated from the base 110, or the locking assembly 120 no longer applies a force to the to-be-locked component 12 to keep it on the base 110.

[0114] The operation assembly 130 is configured to be operated by a user to trigger the unlocked state of the locking assembly 120, that is, the operation assembly 130 is adapted to be operated by a user and is connected with the locking assembly 120 to transmit a force to change the state of the locking assembly 120, for example, to switch the locking assembly 120 from the locked state to the unlocked state, thereby facilitating the subsequent separation of the to-be-locked component 12 from the base 110.

[0115] The holding assembly 140 is configured to maintain the unlocked state of the locking assembly 120 after the unlocked state is triggered, that is, by setting the holding assembly 140, the locking assembly 120 is maintained in a state that allows the to-be-locked component 12 to be separated from the base 110, thereby facilitating the subsequent removal of the to-be-locked component 12 from the base 110, and the to-be-locked component 12 can be kept at the position when it is locked with the base 110. Therefore, when applied to the integration of the aforementioned hard disk, PCIe card, GPU card, fan module and other electronic elements on the server 11 and other devices, the disconnection of the electrical connection between the electronic elements and other devices due to misoperation can be avoided.

[0116] The retaining assembly 140 is movably connected with the base 110 or the to-be-locked component 12 to release the unlocked state after the base 110 and the to-be-locked component 12 can be relatively separated, that is, after the to-be-locked component 12 is separated from the base 110, the locking assembly 120 is no longer kept in the unlocked state, facilitating subsequent installation of the to-be-locked component 12 to the base 110.

[0117] With the above scheme, through cooperation of the locking assembly 120, the operation assembly 130 and the retaining assembly 140, when the user uses the operation assembly 130, the locking assembly 120 is unlocked with the to-be-locked component 12, and the to-be-locked component 12 can be further separated from the base 110. Compared with the conventional threaded connection, buckle connection and the like, the to-be-locked component 12 can be conveniently detached from the base 110, facilitating operation. Meanwhile, the to-be-locked component 12 only has a degree of freedom of being separated from the base 110, rather than being directly separated from the base 110. When the electronic element is assembled, this unlocking mode avoids abnormal interruption of connection between the electronic element and other parts electrically connected thereto due to misoperation to a certain extent.

[0118] As a specific structure of the retaining assembly 140 for keeping or switching the state of the locking assembly 120, refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, in the exemplary embodiment, the retaining assembly 140 comprises a retaining piece 141.

[0119] The retaining piece 141 is movably arranged on the base 110 to have at least a retaining position and a avoiding position relative to the base 110. As a first specific example, after the operation assembly 130 triggers the unlocking state of the locking assembly 120, the retaining piece 141 in the retaining position blocks the operation assembly 130 to keep the locking assembly 120 in the unlocked state, that is, the retaining piece 141 is connected with the operation assembly 130, for example, the retaining piece 141 is in contact with the operation assembly 130, and the state switching of the locking assembly 120 is limited by blocking the operation assembly 130, so that the to-be-locked component 12 can be separated from the base 110 at this time.

[0120] As a second specific example, after the locking assembly 120 is triggered by the operation assembly 130 to be in the unlocked state, the retaining piece 141 in the retaining position blocks the locking assembly 120 to keep the locking assembly 120 in the unlocked state, that is, the retaining piece 141 is directly connected with the locking assembly 120 to prevent the state switching of the locking assembly 120, so that the to-be-locked component 12 can be separated from the base 110 at this time.

[0121] Of course, as a third specific example, the locking assembly 120 can also be configured to be triggered by the operating assembly 130 to be in the unlocked state, and the retaining member 141 in the retaining position is connected to both the locking assembly 120 and the operating assembly 130 to prevent the state switching of the locking component. By limiting the locking device 100 in the unlocked state by the retaining member 141, the to-be-locked component 12 can be separated from the base 110.

[0122] For other limitations that the retaining member 141 is movably connected to the base 110, when the retaining member 141 is in the avoiding position, the retaining member 141 avoids the operating assembly 130 and / or the locking assembly 120 to enable the locking assembly 120 to be released from the unlocked state. That is, when the retaining member 141 is in the avoiding position, the retaining member 141 avoids at least one of the operating assembly 130 and the locking assembly 120, so that the operating assembly 130 and / or the locking assembly 120 can move relative to the base 110 and in turn be released from the unlocked state. With the above scheme, the state of the locking assembly 120 is changed by the movement of the retaining member 141, so that the state of the locking device 100 is adjusted when the to-be-locked component 12 is assembled or disassembled to ensure the smooth operation of the to-be-locked component 12.

[0123] For the purpose of facilitating user operation, it can be further limited that when the retaining member 141 is in the retaining position, at least part of the retaining member 141 is located on the movement path of the relative separation between the base 110 and the to-be-locked component 12, so as to contact the retaining member 141 when the to-be-locked component 12 is separated from the base 110 and move the retaining member 141 from the retaining position to the avoiding position.

[0124] With the above scheme, when the to-be-locked component 12 is disassembled from the base 110, the to-be-locked component 12 can apply a force to the retaining member 141 to move the retaining member 141 by contacting the retaining member 141, and the retaining member 141 moves to the avoiding position to provide space for the displacement of the operating assembly 130 or the locking assembly 120, so that the specific structure of the operating assembly 130 or the locking assembly 120 can be further configured, for example, to release the locking assembly 120 from the unlocked state, or to restore the operating assembly 130 to the position or state before being operated by the user to unlock the to-be-locked component 12, so as to facilitate subsequent relocking of the to-be-locked component 120 or reusing of the operating assembly 130 for unlocking.

[0125] In a specific scheme, refer to Figure 1 , Figure 3 and Figure 4As shown, the retaining member 141 has a first guide surface 141a. The first guide surface 141a is configured to be located on the active path of the base 110 and the to-be-locked component 12 relative to each other when the retaining member 141 is located at the retaining position. So that when the to-be-locked component 12 is separated from the base 110, the first guide surface 141a is in contact with the to-be-locked component 12 and guides the retaining member 141 to move from the retaining position to the avoiding position under the pushing of the to-be-locked component 12.

[0126] As a specific example of the to-be-locked component 12 cooperating with the first guide surface 141a to guide the retaining member 141 to move, for example, the to-be-locked component 12 can be made to move in a straight path and separate from the base 110, that is, the to-be-locked component 12 is in sliding connection with the base 110, and the first guide surface 141a is a plane inclined to the straight line where the straight path is located. During the process that the to-be-locked component 12 separates from the base 110, at least for a distance, the to-be-locked component 12 is in contact with the first guide surface 141a and exerts pressure on the first guide surface 141a, so that the first guide surface 141a drives the retaining member 141 to move, thereby achieving the movement of the operating assembly 130 and / or the locking assembly 120 to a new position or changing the state during the process that the to-be-locked component 12 separates from the base 110.

[0127] For a specific form of the active connection between the retaining member 141 and the base 110, for example, the retaining member 141 and the base 110 constitute a sliding connection. In a specific scheme, as shown in Figure 3 、 Figure 4 and Figure 7 , it can be defined that the base 110 is provided with a first sliding groove 110a. The first sliding groove 110a is used for the retaining member 141 to be placed in to make the retaining member 141 in sliding connection with the base 110, and the first sliding groove 110a is used to limit the position of the retaining member 141 on the base 110, so that the retaining member 141 is stably retained on the base 110 and the movement direction of the retaining member 141 relative to the base 110 is limited.

[0128] Considering the actual application, it is often necessary to limit the distance that the retaining member 141 can move relative to the base 110, and to limit the specific spatial position of the retaining member 141 when it is in the retaining position and the avoiding position. As shown in Figure 3 、 Figure 4 and Figure 7 , for example, the base 110 can be further provided with a first limiting portion 110b in the application. At the same time, the retaining member 141 is further provided with a first matching portion 141b.

[0129] The first limiting portion 110b is configured to cooperate with the retaining member 141 to prevent the retaining member 141 from disengaging from the first sliding slot 110a. The first cooperating portion 141b and the first limiting portion 110b constitute a sliding connection by interfitting. By interfitting the first limiting portion 110b and the first cooperating portion 141b, on the one hand, the retaining member 141 is prevented from disengaging from the first sliding slot 110a when the retaining member 141 is assembled to the base 110, and on the other hand, the interfitting of the first limiting portion 110b and the first cooperating portion 141b also limits the position and distance of the retaining member 141 relative to the base 110, which is conducive to stable use of the retaining member 141 on the base 110.

[0130] For the specific forms of the first limiting portion 110b and the first cooperating portion 141b, refer to Figure 4 and Figure 7 The first limiting portion 110b is configured as a first protrusion 110c protruding from the slot wall of the first sliding slot 110a; the first cooperating portion 141b is configured as a first limiting slot 141c formed on the retaining member 141; and the first protrusion 110c is at least partially embedded in the first limiting slot 141c. By interfitting the first protrusion 110c and the first limiting slot 141c, the retaining member 141 is prevented from disengaging from the first sliding slot 110a, and by configuring the specific position of the first protrusion 110c on the base 110, the retaining member 141 is blocked by the first protrusion 110c when sliding, thereby limiting the displacement of the retaining member 141 relative to the base 110.

[0131] As mentioned above, the retaining member 141 controls the state switching of the locking assembly 120 through its own displacement, and in order to make this control ability more easily applied in practice, in some embodiments, refer to Figure 2 and Figure 4 The retaining assembly 140 further comprises a first type of reset member 142.

[0132] The first type of reset member 142 and the retaining member 141 constitute a force transmission connection to make the retaining member 141 tend to remain in the retaining position. By providing the first reset member, the retaining member 141 has a tendency to remain in a specific position relative to the base 110, which facilitates the configuration of the cooperation relationship between the retaining member 141 and components such as the operating assembly 130 and the locking assembly 120 in the locking device 100 according to the position of the retaining member 141.

[0133] As a specific scheme, refer to Figure 4As shown, the first type of reset member 142 is configured as a first spring 143 arranged between the base 110 and the retaining member 141, and the retaining member 141 tends to move to the retaining position by the elastic force of the first spring 143, so as to ensure that the retaining member 141 can be in contact with the retaining member 141 when the to-be-locked component 12 is separated from the base 110, and the retaining member 141 can realize the function of controlling the locking assembly 120 to release the unlocked state.

[0134] It can be understood that the present application can realize the switching of the locking device 100 from the locked state to the unlocked state by the user using the operation assembly 130, so as to subsequently separate the to-be-locked component 12 from the base 110. The specific structure of the operation assembly 130 for realizing the foregoing function will be exemplarily described below.

[0135] In some embodiments, referring to Figure 3 and Figure 5 As shown, the operation assembly 130 comprises an operation member 131. The operation member 131 is movably arranged on the base 110 to have at least a trigger position and a reset position relative to the base 110. When the operation assembly 130 triggers the unlocked state of the locking assembly 120, the operation member 131 is located at the trigger position and is in contact with the locking assembly 120 to prevent the locking assembly 120 from switching from the unlocked state to the locked state. By movably arranging the operation member 131 on the base 110, the locking assembly 120 is blocked when the operation member 131 is at the trigger position, and the to-be-locked component 12 is unlocked.

[0136] For another limitation that the operation member 131 is movably arranged on the base 110, when the operation member 131 is at the reset position, the operation member 131 avoids the locking assembly 120 so that the locking assembly 120 can switch from the unlocked state to the locked state. Therefore, by moving the operation member 131 between the reset position and the trigger position, the locking assembly 120 realizes the locking and unlocking of the to-be-locked component 12.

[0137] The operation assembly 130 in the present application can cooperate with the retaining assembly 140 to realize that the operation member 131 can be kept at the trigger position before the to-be-locked component 12 is separated from the base 110, thereby facilitating the subsequent separation of the to-be-locked component 12 from the base 110.

[0138] In a specific scheme, referring to Figure 3 , Figure 5 and Figure 7As shown, the operation member 131 is provided with a clamping portion 131a. The clamping portion 131a is used to cooperate with the retaining member 141 to retain the operation member 131 in the trigger position. When the operation member 131 is in the trigger position, the retaining member 141 in the retaining position clamps the clamping portion 131a to prevent the operation member 131 from moving from the trigger position to the reset position. By clamping the clamping portion 131a with the retaining member 141, the movement of the operation member 131 relative to the base 110 is limited by the retaining member 141, so that the operation member 131 is retained in the trigger position, and the retaining member 141 in the trigger position prevents the locking assembly 120 from switching state, so that the locking assembly 120 is retained in the unlocked state.

[0139] In a further aspect, the retaining member 141 is in the avoiding position to avoid the clamping portion 131a, so that the operation member 131 can move between the trigger position and the reset position. By moving the retaining member 141 between the avoiding position and the retaining position, the operation member 131 can be retained in the trigger position or can be moved from the trigger position to the reset position to control the state switching of the locking assembly 120.

[0140] In a more specific aspect, referring to Figure 3 and Figure 7 As shown, the retaining member 141 is formed with an avoiding slot 141d. The avoiding slot 141d is embedded with the clamping portion 131a when the retaining member 141 is in the trigger position. When the operation member 131 is in the trigger position and the retaining member 141 is in the retaining position, the slot wall of the avoiding slot 141d blocks the clamping portion 131a to prevent the clamping portion 131a from disengaging from the avoiding slot 141d.

[0141] With the above aspect, the avoiding slot 141d is provided on the retaining member 141 for the clamping portion 131a to be embedded, the retaining member 141 and the operation member 131 have a relatively small space occupation of the overall structure configured to achieve the state switching of the locking assembly 120, and the connection between the retaining member 141 and the operation member 131 is tight. The clamping portion 131a and the avoiding slot 141d are embedded to prevent the operation member 131 from being reset, and a relatively simple structure is used to achieve the function of controlling the state switching of the locking assembly 120.

[0142] To enable the operating member 131 to move to the reset position for subsequent use to unlock the locked component 12 and the base 110, the retaining member 141 is further limited to a position where the groove wall of the clearance groove 141d avoids the engaging portion 131a, allowing the operating member 131 to move between the trigger position and the reset position. That is, when the retaining member 141 is in the clearance position, the groove wall of the clearance groove 141d is misaligned with the surface of the engaging portion 131a. Therefore, the retaining member 141 no longer obstructs the operating member 131, allowing it to move to the reset position. This enables the operating member 131 to be used again to unlock the locked component 12, and also allows the locking device 100 to be released from its unlocked state, allowing it to be used again to lock the locked component 12 mounted on the base 110.

[0143] When the retainer 141 is in the retaining position, if the operating member 131 needs to move from the reset position to the trigger position, the latching part 131a needs to be able to fit into the relief groove 141d. However, in actual implementation, there may be a situation where the retainer 141 blocks the movement of the latching part 131a. Refer to Figure 3 , Figure 4 and Figure 5 As shown, at this time, one of the retainer 141 and the operating member 131 may be further defined to have a second guide surface 141e.

[0144] The second guide surface 141e is configured to contact the other of the retaining member 141 and the operating member 131 when the operating member 131 moves from the reset position to the trigger position, thereby guiding the retaining member 141 from the holding position to the avoidance position so that the engaging portion 131a is embedded in the avoidance groove 141d. Taking the operating member 131 as a sliding object on the base 110 as an example, the second guide surface 141e can be configured to be a plane inclined to the sliding direction of the operating member 131. Thus, when the operating member 131 moves from the reset position to the trigger position, the second guide surface 141e pushes or drives the retaining member 141 to move relative to the base 110 to the avoidance position. At this time, the surface of the retaining member 141 avoids the engaging portion 131a, so that the engaging portion 131a is embedded in the avoidance groove 141d. Subsequently, for example, the aforementioned first spring 143 is used to reset the retaining member 141 to the holding position, realizing the engagement of the engaging portion 131a and the avoidance groove 141d.

[0145] As a specific plan, refer to Figure 2 and Figure 5 As shown, the operating component 130 may further include a second type of reset member 132. The second type of reset member 132 and the operating member 131 form a force-transmitting connection to keep the operating member 131 in the reset position.

[0146] The second reset member is arranged to make the operating member 131 have a tendency to keep in a specific position, and facilitate the operating member 131 to be driven by the second reset member 132 to move to the reset position when the retaining member 141 is in the avoiding position, and the retaining member 141 can be driven by the to-be-locked part 12 to move to the avoiding position when the to-be-locked part 12 is separated from the base 110, so that the second reset member 132 can be arranged to automatically reset the operating member 131 when the to-be-locked part 12 is separated from the base 110, and facilitate the subsequent use of the operating member 131, so as to further simplify the operation mode of the operation assembly 130, thereby facilitating the assembly and disassembly of the to-be-locked part 12.

[0147] More specifically, as shown in Figure 5 , the second reset member 132 is configured as a second spring 133 arranged between the base 110 and the operating member 131, and the second spring 133 is used to drive the operating member 131 to reset to the reset position by the elastic force of the second spring 133.

[0148] For the specific form of the movable connection between the operating member 131 and the base 110, for example, the operating member 131 and the base 110 form a sliding connection. In a specific scheme, as shown in Figure 3 、 Figure 5 and Figure 7 , the base 110 can be further provided with a second sliding groove 110d. The second sliding groove 110d is used for the operating member 131 to be placed in to make the operating member 131 slide to the base 110. The second sliding groove 110d is used to limit the position of the operating member 131 on the base 110, so as to make the operating member 131 stably keep on the base 110 and limit the moving direction of the operating member 131 relative to the base 110.

[0149] Considering that in actual application, it is often necessary to limit the distance that the operating member 131 can move relative to the base 110, and limit the specific spatial position of the operating member 131 when it is in the trigger position and the reset position, as shown in Figure 3 、 Figure 5 and Figure 7 , the base 110 can be further provided with a second limiting part 110e in the application. Meanwhile, the operating member 131 is further provided with a second matching part 131b.

[0150] The second limiting portion 110e is configured to cooperate with the operating member 131 to prevent the operating member 131 from being separated from the second sliding slot 110d. The second cooperating portion 131b and the second limiting portion 110e constitute a sliding connection by mutual embedding. By mutual embedding of the second limiting portion 110e and the second cooperating portion 131b, the operating member 131 is assembled to the base 110, and the operating member 131 is prevented from being separated from the second sliding slot 110d. The mutual embedding of the second limiting portion 110e and the second cooperating portion 131b also limits the position and distance of the operating member 131 relative to the base 110, which is conducive to stable use of the operating member 131 on the base 110.

[0151] For the specific forms of the second limiting portion 110e and the second cooperating portion 131b, refer to Figure 3 、 Figure 5 and Figure 7 . Exemplarily, the second limiting portion 110e is configured as a second protrusion 110f protruding from the groove wall of the second sliding slot 110d; the second cooperating portion 131b is configured as a second limiting groove 131c formed on the operating member 131; and the second protrusion 110f is at least partially embedded in the second limiting groove 131c. By embedding of the second protrusion 110f and the second limiting groove 131c, the operating member 131 is prevented from being separated from the second sliding slot 110d. By configuring the specific position of the second protrusion 110f on the base 110, the operating member 131 is blocked by the second protrusion 110f when sliding, thereby limiting the displacement of the operating member 131 relative to the base 110.

[0152] It can be understood that the present application can realize locking and unlocking of the to-be-locked component 12 by switching of the locking assembly 120 from the locked state to the unlocked state, which is conducive to assembly and disassembly of the to-be-locked component 12. The specific structure of the locking assembly 120 for realizing the foregoing functions will be exemplarily described below.

[0153] In some embodiments, refer to Figure 2 、 Figure 3 、 Figure 6 and Figure 7 . The locking assembly 120 comprises a locking member 121. The locking member 121 is movably arranged on the base 110 to have at least a locking position and an unlocking position relative to the base 110. When the locking assembly 120 is in the locked state, the locking member 121 is located at the locking position, and at least a part of the locking member 121 is located on a movement path relative to the base 110 and the to-be-locked component 12 to separate, so as to prevent the to-be-locked component 12 from being separated from the base 110.

[0154] The locking member 121 is movably connected to the base 110, and when the locking member 121 is in the locking position, the locking member 121 can lock the to-be-locked component 12, specifically, by blocking the path of the to-be-locked component 12 when the to-be-locked component 12 is separated from the base 110, and in actual use, the locking member 121 can further be limited to be in the locking position and to be separated from the to-be-locked component 12 and to block the displacement of the to-be-locked component 12 relative to the base 110, so as to fix the to-be-locked component 12 on the base 110.

[0155] In addition, the locking member 121 is movably connected to the base 110, and when the locking member 121 is in the locking position, the locking member 121 can lock the to-be-locked component 12, specifically, by blocking the path of the to-be-locked component 12 when the to-be-locked component 12 is separated from the base 110, and in actual use, the locking member 121 can further be limited to be in the locking position and to be separated from the to-be-locked component 12 and to block the displacement of the to-be-locked component 12 relative to the base 110, so as to fix the to-be-locked component 12 on the base 110.

[0156] When the locking member 121 is in the unlocking position, the locking member 121 blocks the movement of the to-be-locked component 12, which is not conducive to the integration of the to-be-locked component 12 on the base 110. Therefore, with reference to Figure 3 and Figure 6 The locking member 121 further has a third guide surface 121a. The third guide surface 121a is configured to be located on the movement path of the to-be-locked component 12 when the to-be-locked component 12 is combined with the base 110. When the to-be-locked component 12 is combined with the base 110, the first guide surface 141a is in contact with the to-be-locked component 12 to guide the locking member 121 to move from the locking position to the unlocking position under the pushing of the to-be-locked component 12.

[0157] In a specific scheme, the to-be-locked component 12 is integrated on the base 110 in a sliding manner, and correspondingly, the third guide surface 121a can be a plane inclined to the sliding direction of the to-be-locked component 12. Thus, during the integration of the to-be-locked component 12 on the base 110, the to-be-locked component 12 can be in contact with the third guide surface 121a, and then the third guide surface 121a is pressed to push the locking member 121 to move from the locking position to the unlocking position, until the to-be-locked component 12 moves to the side of the locking member 121. Then, the to-be-locked component 12 is positioned on the base 110 by resetting the locking member 121 to the locking position by using an additional technical means.

[0158] As an example of the aforementioned additional technical means for resetting the locking member 121 from the unlocking position to the locking position, with reference toFigure 2 and Figure 6 As shown in

[0159] By setting the third type of reset member 122, an action force is applied to the locking member 121 in the unlocked position. When the operating member 131 or the retaining member 141 does not hinder the displacement of the locking member 121, the locking member 121 can be reset to the locked position by the action force provided by the third type of reset member 122, and after the to-be-locked component 12 is installed on the base 110, the locking member 121 can be used to limit the displacement of the to-be-locked component 12, thereby achieving stable installation of the to-be-locked component 12 on the locking device 100.

[0160] In a specific scheme, referring to Figure 6 As shown in

[0161] The locking assembly 120 in the present application can cooperate with the operating assembly 130 to achieve the purpose that the locking member 121 can be kept in the unlocked position before the to-be-locked component 12 is separated from the base 110, thereby facilitating subsequent separation of the to-be-locked component 12 from the base 110.

[0162] In a specific scheme, when the locking assembly 120 is in the unlocked state, the operating member 131 contacts the locking member 121 to prevent the locking member 121 from moving from the unlocked position to the locked position. For example, when the locking assembly 120 is in the unlocked state, the operating member 131 in the triggering position releases the locking member 121, assembles the locking member 121, and prevents the displacement of the locking member 121, so that the spatial position of the locking member 121 is staggered with the space through which the to-be-locked component 12 separates from the base 110, thereby enabling the to-be-locked component 12 to be smoothly detached from the locking device 100.

[0163] The locking member 121 can also cooperate with the operating member 131 to keep the locking member 121 in the unlocked position. As an example, referring to Figure 3 , Figure 6 and Figure 7 As shown in

[0164] In specific solutions, the locking member 121 is slidingly connected with the base 110, and the fourth guide surface 121b is a surface formed on the locking member 121 and inclined to a straight line along the sliding direction of the locking member 121. Thus, when the operating member 131 moves from the reset position to the trigger position, the fourth guide surface 121b guides the locking member 121 to move after the operating member 131 contacts the locking member 121, so that the locking member 121 moves from the locking position to the unlocking position, i.e., the locking assembly 120 switches from the locked state to the unlocked state, and then the to-be-locked component 12 can be separated from the base 110.

[0165] In more specific solutions, as shown in Figure 3 、 Figure 5 and Figure 6 , a contact portion 131d can be arranged at one end of the operating member 131 close to the locking member 121. The contact portion 131d is specifically, for example, a rotating wheel, which can contact the fourth guide surface 121b and apply a force to the fourth guide surface 121b to push the locking member 121 to move when the operating member 131 moves from the reset position to the trigger position, so as to realize the movement of the locking member 121 from the locking position to the unlocking position.

[0166] For the specific form of the movable connection between the locking member 121 and the base 110, for example, the locking member 121 and the base 110 are slidingly connected. In specific solutions, as shown in Figure 7 , the base 110 can further be provided with a third sliding groove 110i. The third sliding groove 110i is used for the locking member 121 to be placed in to slidingly connect the locking member 121 to the base 110. The third sliding groove 110i is used to limit the position of the locking member 121 on the base 110, so as to stably keep the locking member 121 on the base 110 and limit the movement direction of the locking member 121 relative to the base 110.

[0167] Considering that in actual applications, it is often necessary to limit the distance that the locking member 121 can move relative to the base 110, and to limit the specific spatial position of the locking member 121 when it is in the locking position and the unlocking position, as shown in Figure 3 、 Figure 6 and Figure 7 , the base 110 can further be provided with a third limiting portion 110g. Correspondingly, the locking member 121 can further be provided with a third matching portion 121c.

[0168] The third limiting portion 110g is configured to cooperate with the locking member 121 to prevent the locking member 121 from disengaging from the third sliding slot 110i. The third cooperating portion 121c and the third limiting portion 110g form a sliding connection by interfitting with each other. By interfitting the third limiting portion 110g and the third cooperating portion 121c, the locking member 121 is prevented from disengaging from the third sliding slot 110i when the locking member 121 is assembled to the base 110. The interfitting of the third limiting portion 110g and the third cooperating portion 121c also limits the position and distance of the movement of the locking member 121 relative to the base 110, which is conducive to the stable use of the locking member 121 on the base 110.

[0169] For the specific forms of the third limiting portion 110g and the third cooperating portion 121c, refer to Figure 3 、 Figure 6 and Figure 7 . For example, the third limiting portion 110g is configured as a third protrusion 110h protruding from the slot wall of the third sliding slot 110i; the third cooperating portion 121c is configured as a third limiting slot 121d formed on the locking member 121; and the third protrusion 110h is at least partially embedded in the third limiting slot 121d.

[0170] By interfitting the third protrusion 110h and the third limiting slot 121d, the locking member 121 is prevented from disengaging from the third sliding slot 110i. By configuring the specific position of the third protrusion 110h on the base 110, the locking member 121 is blocked by the third protrusion 110h when sliding, thereby limiting the displacement of the locking member 121 relative to the base 110.

[0171] In some embodiments, refer to Figure 7 . The base 110 is provided with a limiting sliding slot 110j. The limiting sliding slot 110j is configured to receive at least part of the to-be-locked component 12. When the locking assembly 120 is in the locked state, at least part of the locking assembly 120 is embedded in the limiting sliding slot 110j to prevent the to-be-locked component 12 from disengaging from the limiting sliding slot 110j and separating from the base 110. In a specific scheme, for example, a protruding portion 12a is formed on the to-be-locked component 12, and the protruding portion 12a is embedded in the limiting sliding slot 110j when the to-be-locked component 12 is combined to the base 110. The movement direction of the to-be-locked component 12 is guided by the cooperation of the protruding portion 12a and the limiting sliding slot 110j. In a more specific scheme, the protruding portion 12a contacts the third guide surface 121a during the combination to the base 110 to push the locking member 121 to move. After the protruding portion 12a disengages from the locking member 121, the locking member 121 is reset to the locking position to prevent the protruding portion 12a from sliding along the limiting sliding slot 110j, thereby achieving the fixation and limiting of the to-be-locked component 12 on the locking device 100.

[0172] In a more specific scheme, refer toFigures 1 to 7 As shown, two or more number of limiting grooves 110j can be arranged on the base 110, and correspondingly, two or more number of protruding portions 12a can be formed on the to-be-locked component 12 to cooperate with the plurality of limiting grooves 110j, so as to increase the number of connecting parts between the base 110 and the to-be-locked component 12, thereby improving the connecting strength of the connecting structure between the base 110 and the to-be-locked component 12. Meanwhile, two or more number of contact portions 131d can be arranged on the operating member 131 to guide the movement of the plurality of locking members 121, and two or more number of retaining members 141 can be movably arranged on the base 110 to cooperate with the operating member 131.

[0173] Alternatively, referring to Figure 8 As shown, in some embodiments, the locking device 100' can also be configured to have only one limiting groove 110j' arranged on the base 110', and correspondingly, the number of the locking assembly 120', the operating assembly 130' and the retaining assembly 140' can also be only one, so as to simplify the structure of the locking device 100'.

[0174] In some embodiments, referring to Figure 7 As shown, the base 110 includes a first support 111 and a second support 112 which are embedded with each other. The first support 111 and the second support 112 are fixed by, for example, snap buckling or the like. The locking assembly 120, the operating assembly 130 and the retaining assembly 140 are arranged between the first support 111 and the second support 112, so as to be positioned and installed in the space formed by the first support 111 and the second support 112. The limiting groove 110j penetrates at least one of the first support 111 and the second support 112, so that at least part of the to-be-locked component 12 passes through the first support 111 or the second support 112, so as to install the to-be-locked component 12 on the locking device 100.

[0175] According to a second aspect of the present application, referring to Figure 9 As shown, a mounting device 200 is provided, which includes a body 210 and the above-mentioned locking device 100. The body 210 is formed with a receiving cavity 211 which receives the to-be-locked component 12. The locking device 100 is fixedly arranged in the receiving cavity 211, so that the to-be-locked component 12 is detachably installed in the receiving cavity 211 by the locking device 100. The mounting device 200 has the beneficial effects of the above-mentioned locking device 100, which will not be repeated herein. When in use, the to-be-locked component 12 is detachably fixed in the receiving cavity 211 by the locking device 100, so as to be protected by the body 210.

[0176] In some embodiments, the mounting device 200 includes at least two locking devices 100. The at least two locking devices 100 are spaced apart within the receiving cavity 211 so that the component to be locked 12 can be locked between two adjacent locking devices 100. By connecting each side of the component to be locked 12 to a locking device 100, it is advantageous to make the component to be locked 12 more stably connected to the mounting device 200.

[0177] According to the third aspect of this application, referring to Figures 10 to 12 As shown, an electronic device 10 is provided, including a lockable component 12 and the aforementioned mounting device 200; wherein the lockable component 12 is detachably fixed within the receiving cavity 211 of the mounting device 200. This electronic device 10 possesses all the beneficial effects of the aforementioned mounting device 200, which will not be elaborated further here.

[0178] In some embodiments, electronic device 10 includes server 11.
