Description

Technical Field

[0001] This application relates to the field of lock equipment technology, and in particular to an unlocking accessory and lock system. Background Technology

[0002] With the development of society and economy and the progress of technology, various types of locks with electronic lock cylinders are constantly emerging. Among them, some electronic lock cylinders with data interfaces can be connected to the data interface through computer keys, data cables, etc., to realize data transmission and / or power transmission, and to perform locking and unlocking operations on the lock.

[0003] To make the data cable easy to carry and convenient to connect with locks, the data cable in unlocking accessories is usually designed to be unidirectionally retractable. However, existing unlocking accessories with unidirectional retractable data cables typically employ a structure design of a moving circuit board and a fixed conductive plate. The fixed data cable is connected to the fixed conductive plate, the metal contacts on the moving circuit board are connected to the circular conductive rails on the fixed conductive plate, and the movable data cable is then connected to the moving circuit board to achieve the connection between the fixed and movable data cables. This frequent stretching or retracting of the movable data cable causes wear on the metal contacts between the movable data cable and the moving circuit board, leading to poor conductivity between the fixed and movable data cables, severely impacting the user experience of unlocking locks using the unlocking accessory. Utility Model Content

[0004] The main purpose of this application is to provide an unlocking accessory that addresses the problem of poor conductivity caused by frequent stretching or contraction of the data cable in existing unlocking accessories.

[0005] To achieve the above objectives, this application proposes an unlocking accessory for connecting a lock to a smart device to enable locking and unlocking of the lock. The unlocking accessory includes a housing assembly and a data cable; wherein...

[0006] The housing assembly includes a housing, a winding frame, and a first elastic element. The housing has a receiving cavity and a first wire outlet and a second wire outlet communicating with the receiving cavity. The winding frame is rotatably mounted in the receiving cavity.

One end of the cable body is connected to the first interface, and the other end of the cable body is sequentially wrapped around the outer side of the sliding part, the inner side of the folding part, and the outer side of the folding part before connecting to the second interface.

[0008] When the second interface extends out of the second outlet hole under the action of external force, it drives the winding frame to rotate in the first direction, and causes the first elastic element to store elastic potential energy. When the external force on the second interface is removed, the first elastic element releases elastic potential energy to drive the winding frame to rotate in the second direction, so that part of the wire is folded and stored on the outside of the folded part and the outside of the sliding part.

[0009] In some embodiments of this application, the data cable has an extended state and a retracted state relative to the housing assembly. When the data cable is in the extended state, the second interface extends out of the second outlet hole. When the data cable is in the retracted state, the second interface is retracted into the housing.

[0010] The receiving cavity is provided with an anti-rotation part, and the winding frame is provided with a first abutment part and a second abutment part at intervals around its periphery. When the data cable is in the extended state, the anti-rotation part abuts and cooperates with the first abutment part to restrict the winding frame from rotating in the first direction. When the data cable is in the retracted state, the anti-rotation part abuts and cooperates with the second abutment part to restrict the winding frame from rotating in the second direction.

[0012] The unlocking accessory also includes a button assembly, which is elastically mounted on the mounting part along the rotation axis of the winding frame. The side of the button assembly away from the mounting part is exposed on the surface of the housing through the mounting hole. The button assembly is also provided with a locking block. When the data cable is in the extended state, the locking block abuts against the locking groove to restrict the rotation of the winding frame.

[0013] In some embodiments of this application, the mounting part includes a column, a mounting groove is recessed on the side of the column near the mounting hole, a guide groove is provided on the side wall of the mounting groove, and the guide groove extends along the axial direction of the column.

[0014] The button assembly includes a button and a second elastic element. The button is provided with a locking block on its periphery. The button is movably mounted in the mounting groove, and the locking block is slidably engaged with the guide groove. The second elastic element is elastically mounted between the groove wall of the mounting groove and the button.

[0015] In some embodiments of this application, the bottom wall of the mounting groove is provided with a first connecting hole through the axis of the rotating shaft, and the cavity wall of the receiving cavity is provided with a shaft body, which passes through the first connecting hole and is inserted into the second connecting hole of the button.

[0016] In some embodiments of this application, the first elastic element is a torsion spring, and a torsion spring groove is recessed on the side of the column away from the mounting hole. The torsion spring is housed in the torsion spring groove, one elastic arm of the torsion spring elastically abuts against the outer shell, and the other elastic arm of the torsion spring elastically abuts against the winding frame.

[0017] In some embodiments of this application, the sliding part includes a plurality of first columns, which are spaced apart circumferentially along the winding frame, and each first column is fitted with a sleeve.

[0018] In some embodiments of this application, the folding portion includes a second column and a vertical arm spaced apart, with the vertical arm disposed adjacent to the sliding portion, the second column located on the side of the vertical arm away from the sliding portion, and the vertical arm extending circumferentially along the winding frame.

[0019] In some embodiments of this application, the outer shell includes an upper shell and a bottom shell. The upper shell is provided with a receiving groove and a first opening and a second opening respectively communicating with the receiving groove. The bottom shell is connected to the upper shell and forms the receiving cavity, the first outlet hole and the second outlet hole by the receiving groove, the first opening and the second opening respectively.

[0020] In some embodiments of this application, the housing assembly further includes a first connecting structure, which is installed in the first outlet hole and has a first receiving channel communicating with the first outlet hole. The first interface is at least partially received in the first receiving channel, and the port of the first interface for docking with the lock is exposed at the end of the first receiving channel away from the first outlet hole.

[0021] And / or, the housing assembly further includes a second connecting structure, which is installed in the second outlet hole and has a second receiving channel communicating with the second outlet hole. The periphery of the second connecting structure is also provided with a clearance opening communicating with the second receiving channel.

[0022] This application also proposes a locking system comprising a lock and the unlocking accessory described in any one of the above descriptions; wherein...

[0023] The lock includes an electronic lock cylinder, which is equipped with a data interface. The first interface is connected to the data interface of the lock, and the second interface is connected to the smart device to connect the lock and the smart device, so as to realize data transmission and / or power transmission between the lock and the smart device, and thereby perform locking and unlocking operations on the lock.

[0024] The unlocking accessory provided in this application embodiment, through the above-described structural configuration, allows the user to connect the first interface to the lock when using their data cable, and then pull the second interface out of the second cable outlet to connect to the smart device, thereby connecting the lock and the smart device to achieve data transmission and / or power transmission between the lock and the smart device, and thus perform the lock-on / lock-off operation. Since pulling the second interface out of the second cable outlet will cause the winding frame to rotate in the first direction, the elastic potential energy stored in the first elastic element is generated. Therefore, after the lock-on / lock-off operation is completed, the connection between the second interface and the smart device is released, and the winding frame will be driven by the elastic force of the first elastic element to rotate in the second direction. In this way, the previously pulled-out cable will be folded and stored on the outside of the folding part and the outside of the sliding part by the action of the winding frame. As can be seen, the technical solution of this application can realize the unidirectional stretching and contraction of a single data cable through the cooperation of the winding frame and the first elastic element. It does not require the connection between the follower circuit board and the data cable, which makes it easy to carry and easy to connect with the lock, while ensuring the conductivity of the data cable, greatly improving the durability of the data cable, and providing users with a good unlocking and locking operation experience.

[0042] This application provides an unlocking accessory 100 for connecting a lock 200 to a smart device 300, enabling data transmission and / or power delivery, and performing unlocking / locking operations on the lock 200. The lock 200 is a smart lock 200 including an electronic lock cylinder. Please refer to the relevant documentation. Figures 1 to 8 The unlocking accessory 100 includes a housing assembly 10 and a data cable 20.

[0043] The housing assembly 10 includes a housing 11, a winding frame 12, and a first elastic member. The housing 11 has a receiving cavity 115 and a first wire outlet hole 114 and a second wire outlet hole 113 respectively communicating with the receiving cavity 115. The winding frame 12 is rotatably mounted in the receiving cavity 115. The winding frame 12 has a sliding part 121 and a folding part 122. The first elastic member is elastically mounted between the winding frame 12 and the housing 11.

[0044] The winding frame 12 can be rotatably mounted in the receiving cavity 115 via a bearing, or it can be mounted in the receiving cavity 115 by inserting it into a rotating shaft. Considering that the winding frame 12 is rotatably mounted in the receiving cavity 115, the cavity is generally flat and disc-shaped. Similarly, the outer contour of the outer shell 11 is also generally disc-shaped. This improves the user's grip on the unlocking accessory 100.

[0045] The first elastic element is elastically installed between the winding frame 12 and the housing 11, and is designed to provide elastic force to the winding frame 12 so that the winding frame 12 can rotate. The first elastic element includes, but is not limited to, a torsion spring 13, a spring steel strip, and a spiral spring.

[0046] The data cable 20 includes a first interface 21, a cable body 22, and a second interface 23. The first interface 21 is fixed to the first outlet hole 114 for docking with the lock 200. The second interface 23 is movably disposed in the second outlet hole 113 for docking with the smart device 300. One end of the cable body 22 is connected to the first interface 21, and the other end of the cable body 22 is sequentially wrapped around the outer side of the sliding part 121, the inner side of the folding part 122, and the outer side of the folding part 122 before being connected to the second interface 23.

[0047] There are several ways to fix the first interface 21 to the first outlet hole 114. Figure 3 and Figure 7 In the example shown, the first interface 21 is fixed to the first cable outlet 114 by a limiting clip 16. Specifically, the limiting clip 16 clamps the cable 22 adjacent to the first interface 21, fixing one end of the cable 22 near the interface, thereby fixing the first interface 21 to the first cable outlet 114. The limiting clip 16 is fixed to the outer casing 11 by a plug-in connection. In other examples, the first interface 21 can be directly fixed to the first cable outlet 114 by a cable clamp or similar device.

[0048] The types of the first interface 21 and the second interface 23 include, but are not limited to, Type-C data interface, Micro-USB data interface, and Lightning data interface. Considering that most people can access smart devices 300, which are mobile phones, and that mobile phones usually have a Type-C data interface, preferably, both the first interface 21 and the second interface 23 are Type-C data interfaces.

[0049] It should be emphasized that the other end of the thread 22 is sequentially wrapped around the outer side of the sliding part 121, the inner side of the folded part 122, and the outer side of the folded part 122. This does not mean that the thread 22 is completely pressed against the outer side of the sliding part 121, the inner side of the folded part 122, and the outer side of the folded part 122. Rather, it means that the thread 22 is adjacent to and passes through the outer side of the sliding part 121, the inner side of the folded part 122, and the outer side of the folded part 122, respectively. Figure 7 As shown, the thread 22 is adjacent to and passes through the inside of the fold 122, but not completely close to it; the thread 22 is adjacent to and passes through the outside of the fold 122, and is completely close to the outside of the fold 122.

[0050] When the second interface 23 extends out of the second outlet hole 113 under the action of external force, it drives the winding frame 12 to rotate in the first direction, and causes the first elastic element to store elastic potential energy. When the external force on the second interface 23 is removed, the first elastic element releases elastic potential energy to drive the winding frame 12 to rotate in the second direction, so that part of the wire 22 is folded and stored on the outside of the folding part 122 and the outside of the sliding part 121.

[0051] It is understandable that when the first direction is counterclockwise, the second direction is clockwise, and when the first direction is clockwise, the second direction is counterclockwise.

[0052] The unlocking accessory 100 provided in this application embodiment, through the above-described structure, allows the user to connect the first interface 21 to the lock 200 when using its data cable 20, and then pull the second interface 23 out of the second cable outlet 113 to connect with the smart device 300, thereby connecting the lock 200 and the smart device 300 to realize data transmission and / or power transmission between the lock 200 and the smart device 300, and thus perform the locking and unlocking operation of the lock 200. Since pulling the second interface 23 out of the second cable outlet 113 will drive the winding frame 12 to rotate in the first direction, the first elastic element stores elastic potential energy. Therefore, after completing the locking and unlocking operation of the lock 200, the connection between the second interface 23 and the smart device 300 is released, and the winding frame 12 will be driven by the elastic force of the first elastic element to rotate in the second direction. In this way, the previously pulled-out cable 22 will be folded and stored on the outside of the folding part 122 and the outside of the sliding part 121 by the action of the winding frame 12. As can be seen, the technical solution of this application can realize the unidirectional stretching and contraction of a single data cable 20 through the cooperation of the winding frame 12 and the first elastic element. It does not require the connection of the follower circuit board to the data cable 20, which makes it easy to carry and easy to dock with the lock 200, while ensuring the conductivity of the data cable 20, greatly improving the durability of the data cable 20, and providing users with a good unlocking and locking operation experience.

[0053] In some examples, such as Figures 3 to 8As shown, the data cable 20 has an extended state and a retracted state relative to the housing assembly 10. When the data cable 20 is in the extended state, the second interface 23 extends out of the second cable outlet 113. When the data cable 20 is in the retracted state, the second interface 23 is retracted into the housing. The receiving cavity 115 is provided with an anti-rotation part 1112. The winding frame 12 is provided with a first abutment part 123 and a second abutment part 124 at intervals around its periphery. When the data cable 20 is in the extended state, the anti-rotation part 1112 abuts against the first abutment part 123 to restrict the winding frame 12 from rotating in the first direction. When the data cable 20 is in the retracted state, the anti-rotation part 1112 abuts against the second abutment part 124 to restrict the winding frame 12 from rotating in the second direction.

[0054] This design aims to prevent the data cable 20 from being pulled out excessively, which would damage the overall structure of the unlocking accessory 100, and to prevent the data cable 20 from being overly retracted, which would make it inconvenient for the user.

[0055] In some examples, such as Figures 3 to 8 As shown, the anti-rotation part 1112 is also located near the second cable outlet 113. When the data cable 20 is in the retracted state, the anti-rotation part 1112 also abuts against the side of the second interface 23 near the cable body 22. This arrangement aims to optimize the structural layout of the unlocking accessory 100, so that the anti-rotation part 1112 restricts the winding frame 12 from rotating in the second direction while restricting the second interface 23 from further retracting.

[0056] In some examples, such as Figures 3 to 8 As shown, a mounting portion is provided at the rotation axis of the winding frame 12, and the outer casing 11 is also provided with a mounting hole 1111 communicating with the receiving cavity 115, and the mounting hole 1111 is set directly opposite the mounting portion. The wall of the mounting hole 1111 is provided with a locking groove 1113. The unlocking accessory 100 also includes a button assembly 30, which is elastically mounted on the mounting portion along the rotation axis of the winding frame 12. The side of the button assembly 30 away from the mounting portion is exposed on the surface of the outer casing 11 through the mounting hole 1111. The button assembly 30 is also provided with a locking block 311. When the data cable 20 is in the extended state, the locking block 311 abuts against the locking groove 1113 to restrict the rotation of the winding frame 12.

[0057] It should be emphasized that the button assembly 30 is elastically mounted on the mounting part along the rotation axis of the winding frame 12. The button assembly 30 can only move relative to the rotation axis of the mounting frame and cannot rotate relative to the winding frame 12. That is, when the winding frame 12 rotates relative to the mounting cavity, the button assembly 30 also rotates synchronously. When the locking block 311 and the locking groove 1113 are in contact and cannot rotate, the winding frame 12 also cannot rotate.

[0058] This design aims to keep the data cable 20 in an extended state through the interaction between the button component 30 and the mounting hole 1111, making it easy for the user to connect the second interface 23 to the smart device 300 and to quickly retract the data cable 20.

[0059] Considering the stability of the engagement between the locking block 311 and the locking groove 113, in some examples, the button assembly 30 is provided with two oppositely arranged locking blocks 311, and two corresponding locking grooves 113 are also provided.

[0060] When the rotation range of the winding frame 12 is set to 180°, and the data cable 20 is in a retracted or extended state, the locking block 311 abuts against the locking groove 113 to restrict the rotation of the winding frame 12. Before using the unlocking accessory 100, the user presses the button assembly 30 to move it along the rotation axis of the mounting bracket, thereby separating the locking block 311 from the locking groove 1113. At this time, the second interface 23 can be pulled out of the second cable outlet 113. When the cable 22 is pulled out to a preset length, i.e., when the data cable 20 is in the extended state, the locking block 311 will abut against the locking groove 1113, restricting the rotation of the winding frame 12. The user presses the button assembly 30 again to move it along the rotation axis of the mounting bracket, thereby separating the locking block 311 from the locking groove 1113 again. The winding frame 12 will then rotate under the elastic drive of the first elastic element, so that the data cable 20 returns to the retracted state.

[0061] If the rotation range of the winding frame 12 is set to less than 180°, when the data cable 20 is in the extended state, the two locking blocks 311 respectively abut against the corresponding locking grooves 113 to restrict the rotation of the winding frame 12. That is, when using the unlocking accessory 100, the second interface 23 is pulled out of the second cable outlet 113. When the cable 22 is pulled out to a preset length, that is, when the data cable 20 is in the extended state, the locking block 311 will abut against the corresponding locking groove 1113 to restrict the rotation of the winding frame 12. At this time, the data cable 20 can remain in the extended state. After the user finishes using the data cable 20, pressing the button assembly 30 causes the button assembly 30 to move along the rotation axis of the mounting bracket, causing the locking block 311 to separate from the locking groove 1113. The winding frame 12 will then rotate under the elastic drive of the first elastic element, so that the data cable 20 returns to the retracted state.

[0062] In some examples, the button assembly 30 may also have two oppositely arranged locking blocks 311, and the two oppositely arranged locking blocks 311 may have different shapes. The mounting hole 1111 has two locking grooves 113 that correspond to the two locking blocks 311 respectively, that is, the two locking grooves 113 are also different in shape. In this way, when the winding frame 12 rotates 180°, the locking blocks 311 are misaligned with the corresponding locking grooves 113, so the rotation range of the winding frame 12 can be greater than 180°.

[0063] In some examples, such as Figures 3 to 8 As shown, the mounting part includes a column 125. A mounting groove 1251 is recessed on one side of the column 125 near the mounting hole 1111. A guide groove 1252 is also provided on the side wall of the mounting groove 1251, and the guide groove 1252 extends axially along the column 125. The button assembly 30 includes a button 31 and a second elastic member 32. A locking block 311 is provided on the periphery of the button 31. The button 31 is movably mounted in the mounting groove 1251, and the locking block 311 slides in cooperation with the guide groove 1252. The second elastic member 32 is elastically mounted between the groove wall of the mounting groove 1251 and the button 31.

[0064] This design aims to improve the user's tactile feedback when operating the button component 30, thereby enhancing the user experience.

[0065] In some examples, such as Figures 3 to 8 As shown, the bottom wall of the mounting groove 1251 is provided with a first connecting hole 1253 through the axis of rotation, and the cavity wall of the receiving cavity 115 is provided with a shaft 1121. The shaft 1121 passes through the first connecting hole 1253 and is inserted into the second connecting hole 312 of the button 31.

[0066] This design aims to improve the stability of the button component 30, thereby enhancing the user's tactile experience when operating the button component 30.

[0067] In some examples, such as Figure 3 and Figure 6 As shown, the first elastic element is a torsion spring 13. A torsion spring groove 1254 is recessed on the side of the column 125 away from the mounting hole 1111. The torsion spring 13 is housed in the torsion spring groove 1254. One spring arm of the torsion spring 13 elastically abuts against the outer shell 11, and the other spring arm of the torsion spring 13 elastically abuts against the winding frame 12.

[0068] This design is intended to facilitate the installation of the first elastic element and the winding frame 12, thereby improving the assembly efficiency of the unlocking accessory 100.

[0069] Specifically, in Figure 3 and Figure 6In the example shown, a slot 1122 is provided on the shaft 1121, and one arm of the torsion spring 13 is accommodated in the slot 1122 to elastically abut against the outer shell 11. The winding frame 12 is provided with an L-shaped groove 126, and the other arm of the torsion spring 13 is accommodated in the L-shaped groove 126 to elastically abut against the winding frame 12.

[0070] Considering that the greater the contact area between the line 22 and the sliding part 121, the greater the resistance, in some examples, such as Figures 3 to 8 As shown, the sliding part 121 includes multiple first posts 1211, which are spaced apart circumferentially along the winding frame 12. This arrangement aims to reduce the contact area between the wire 22 and the sliding part 121, thereby reducing resistance and improving the user experience.

[0071] Of course, in other examples, such as Figure 9 and Figure 10 As shown, the sliding part 121 can be extended along the periphery of the winding frame 12.

[0072] In some examples, such as Figure 3 As shown, each first column 1211 is fitted with a sleeve 1212. This arrangement aims to further reduce resistance and improve the user experience.

[0073] Similarly, considering that the greater the contact area between the line 22 and the fold 122, the greater the resistance, in some examples, such as Figure 7 As shown, the folding section 122 includes a second column 1221 and an arm 1222 spaced apart. The arm 1222 is positioned adjacent to the sliding section 121, while the second column 1221 is located on the side of the arm 1222 away from the sliding section 121. The arm 1222 also extends circumferentially along the winding frame 12. This arrangement aims to reduce the contact area between the cable 22 and the folding section 122, thereby reducing resistance and improving the user experience. Simultaneously, the arm 1222 effectively prevents interference between the cables 22.

[0074] Similarly, each of the second columns 1221 is fitted with a sleeve 1212. Preferably, the sleeve 1212 may have a spherical protrusion on the side away from the winding frame 12 that can slide in contact with the cavity wall of the receiving cavity 115 to improve the stability of the rotation of the winding frame 12 and the sleeve 1212.

[0075] In some examples, such as Figures 3 to 7As shown, the outer casing 11 includes an upper casing 111 and a bottom casing 112. The upper casing 111 is provided with a receiving groove 1114 and a first opening 1115 and a second opening 1116 respectively communicating with the receiving groove 1114. The bottom casing 112 is connected to the upper casing 111 and forms a receiving cavity 115, a first cable outlet 114, and a second cable outlet 113 with the receiving groove 1114, the first opening 1115, and the second opening 1116 respectively. This arrangement is intended to facilitate the manufacturing and assembly of the outer casing 11 and reduce production costs.

[0076] Specifically, in Figure 3 and Figure 4 In the example shown, the bottom shell 112 is provided with a buckle arm 1123, and the upper shell 111 is provided with a buckle groove 1117. The buckle arm 1123 engages with the buckle groove 1117 to achieve the connection between the bottom shell 112 and the upper shell 111. Of course, the bottom shell 112 and the upper shell 111 can also be connected by other connection methods, such as: bonding, welding, etc.

[0077] In some examples, such as Figures 2 to 8 As shown, the housing assembly 10 also includes a first connecting structure 14, which is mounted on the first cable outlet 114 and has a first receiving channel 141 communicating with the first cable outlet 114. The first interface 21 is at least partially received in the first receiving channel 141, and the port of the first interface 21 for mating with the lock 200 is exposed at the end of the first receiving channel 141 away from the first cable outlet 114. This arrangement aims to protect the periphery of the first interface 21 through the first receiving channel 141, preventing it from being damaged by external forces.

[0078] In some examples, such as Figures 2 to 8 As shown, the housing assembly 10 also includes a second connecting structure 15, which is installed in the second cable outlet 113 and has a second receiving channel 151 communicating with the second cable outlet 113. The periphery of the second connecting structure 15 also has a clearance opening communicating with the second receiving channel 151. This design aims to protect the periphery of the second interface 23 from external damage when the data cable 20 is in the retracted state, through the second receiving channel 151. Simultaneously, the clearance opening facilitates the user's pulling out of the second interface 23.

[0079] This application also proposes a lock system, which includes a lock 200 and an unlocking accessory 100 as described above; wherein, this application also proposes a lock system, which includes a lock 200 and an unlocking accessory 100, the specific structure of which refers to the above embodiments. Since this lock system adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, and will not be described in detail here.

[0080] The lock 200 includes an electronic lock cylinder, which is equipped with a data interface. The first interface 21 is connected to the data interface of the lock 200, and the second interface 23 is connected to the smart device 300 to connect the lock 200 and the smart device 300, so as to realize the data transmission and / or power transmission between the lock 200 and the smart device 300, and then perform the locking and unlocking operations on the lock 200.

[0081] The above description is merely an optional embodiment of this application and does not limit the patent scope of this application. Any equivalent structural transformations made based on the inventive concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
