They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0052] In addition, the terms “first”, “second”, etc., if used, are merely used to distinguish between the descriptions and should not be understood as indicating or implying relative importance.

[0053] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0054] This embodiment provides a lock, which is a smart lock that can be unlocked by fingerprint, password, card, key and other methods.

[0055] Please refer to Figure 1 and Figure 2 The smart lock includes a front lock 100, a lock body (not shown) and a rear lock 300. The front lock 100, the lock body and the rear lock 300 are all used to be assembled on the door; wherein, the lock body includes a lock tongue, and the front lock 100 and the rear lock 300 can both cooperate with the lock tongue of the lock body to retract the lock tongue to complete the unlocking.

[0056] The front lock 100 and the rear lock 300 have similar structures, and also have their own different structures; wherein, the front lock 100 and the rear lock 300 both include a shell 110 and a handle device 150, the shell 110 is used to be assembled on the door, the handle device 150 is arranged on the shell 110, and can cooperate with the lock tongue of the lock body to control the lock tongue to retract by pressing or pulling the handle device 150 to unlock.

[0057] Please refer to Figure 2 and Figure 3 The shell 110 includes a bottom shell 120, a panel 130 and a rubber pad 122. The panel 130 and the rubber pad 122 are respectively connected to the opposite sides of the bottom shell 120. The bottom shell 120 is used to be assembled on the door, and the rubber pad 122 is padded between the bottom shell 120 and the door; the handle device 150 includes a handle 160 and an assembly mechanism 170. The handle 160 is assembled on the panel 130 through the assembly mechanism 170, and the handle 160 is distributed on the side of the panel 130 away from the bottom shell 120, and can move relative to the panel 130; wherein, the handle 160 can be matched with the lock tongue of the lock body through the assembly mechanism 170, and when the handle 160 is pressed or pulled, it can drive the lock tongue to retract.

[0058] It should be understood that the rubber pad 122 is not an essential component. In other embodiments, the housing 110 may not include the rubber pad 122.

[0059] The inventor's research found that when the fixing point and the stress point of the handle assembled to the panel by the assembling mechanism are on the panel, the tensile strength of the handle is poor and the problem of loosening is likely to occur.

[0060] To improve the above problems, please refer to Figure 3 and Figure 4 , the assembling mechanism 170 of this embodiment is fixedly connected to the bottom shell 120. In this way, the handle 160 that can move relative to the panel 130 is fixed to the fixing point of the housing 110 through the assembling mechanism 170, and the stress point when the handle 160 moves is on the bottom shell 120, rather than on the panel 130, which can improve the tensile strength of the handle 160 and improve the problem that the handle 160 is likely to loosen relative to the housing 110.

[0061] It should be noted that the fixed connection in this disclosure means that when the assembling mechanism 170 is connected to the bottom shell 120, there will be no accidental relative movement or separation between the assembling mechanism 170 and the bottom shell 120. The specific fixed connection method can refer to welding, riveting or bolt connection, etc. That is to say, the fixed connection in this disclosure includes non-detachable fixed connections and detachable fixed connections. As long as there is no accidental relative movement or separation between the assembling mechanism 170 and the bottom shell 120 when they are connected to each other, it is regarded as a fixed connection.

[0062] Optionally, please refer to Figure 4 and Figure 5 , the bottom shell 120 is provided with an assembling cavity 121, and at least part of the assembling mechanism 170 is accommodated in the assembling cavity 121. In this way, the stability of the assembling mechanism 170 assembled to the bottom shell 120 can be further improved, and the tensile property of the handle 160 assembled to the panel 130 through the assembling mechanism 170 can be improved.

[0063] Furthermore, please refer to Figure 3 and Figure 5 , the bottom shell 120 includes a first bottom plate 123 and a first frame 124. The first frame 124 is connected to the first bottom plate 123 and is distributed circumferentially around the first bottom plate 123 to enclose the assembling cavity 121; the first bottom plate 123 is fixedly connected to the assembling mechanism 170; one end of the first frame 124 away from the first bottom plate 123 extends towards the panel 130, and one end of the first frame 124 away from the first bottom plate 123 abuts against the panel 130. With such a setting, the assembling stability among the assembling mechanism 170, the panel 130 and the bottom shell 120 can be further ensured.

[0064] The connection mode of the first bottom plate 123 and the first frame 124 is integrally formed. Of course, in other embodiments, the connection mode of the first bottom plate 123 and the first frame 124 can also be welding or connection with fasteners such as bolts.

[0065] Optionally, the bottom shell 120 can be prepared from a material with high strength such as carbon steel.

[0066] Of course, in other embodiments, the bottom shell 120 can also be prepared from an aluminum alloy material, which is not specifically limited herein.

[0067] Of course, in other embodiments, the panel 130 is provided with an assembly cavity 121 for accommodating at least part of the assembly mechanism 170.

[0068] Optionally, the panel 130 can be prepared from materials such as carbon steel and aluminum alloy, which is not specifically limited herein.

[0069] Optionally, the handle 160 and the assembly mechanism 170 are configured to be assembled on the bottom shell 120 together with the panel 130. That is, the handle 160 and the assembly mechanism 170 can be pre-assembled on the panel 130 to form a whole, and then modularly assembled on the bottom shell 120. In this way, the ease of operation and efficiency of the assembly can be improved.

[0070] The structure of the assembly mechanism 170 can be selected according to needs; please refer to Figure 4 and Figure 6 , in this embodiment, the assembly mechanism 170 includes a fixing frame 180 and an assembly component 190. The fixing frame 180 is assembled on the panel 130, the assembly component 190 is assembled on the fixing frame 180 and is connected to the handle 160; wherein, the fixing frame 180 is fixedly connected to the bottom shell 120. With such a setting, during assembly, the fixing frame 180 can be pre-assembled on the panel 130 first, and then the handle 160 can be assembled on the panel 130 by using the assembly component 190, so that the assembly mechanism 170 and the handle 160 are pre-assembled on the panel 130 as a whole component, and modularly connected to the bottom shell 120, ensuring the ease of operation of the assembly; and, by fixedly connecting the fixing frame 180 to the bottom shell 120, the fixing point and the stress point of the handle 160 are both on the bottom shell 120, so as to improve the tensile performance of the handle 160.

[0071] In order to improve the ease of operation of pre-assembling the fixing frame 180 on the panel 130, the fixing frame 180 is configured to be in snap-fit with the panel 130. Moreover, through the snap-fit of the fixing frame 180 and the panel 130, the fixing frame 180 can be replaced according to needs, ensuring the ease of maintenance between the fixing frame 180 and the panel 130.

[0072] Further, please refer to Figure 6The panel 130 is connected with a first buckle 132, and the fixing frame 180 is engaged with the first buckle 132. The number of the first buckles 132 is not limited, for example: one, two, three, six, etc.

[0073] Of course, in other embodiments, the fixing frame 180 is connected to the first buckle 132 , and the first buckle 132 is engaged with the panel 130 .

[0074] Alternatively, in other embodiments, the fixing frame 180 and the panel 130 may be connected by bonding or the like, which is not specifically limited here.

[0075] In order to improve the stability of the connection between the fixing frame 180 and the bottom shell 120; please refer to Figure 3 and Figure 6 The lock of this embodiment further includes a first fastener 181 , and the fixing frame 180 and the bottom shell 120 are connected by the first fastener 181 .

[0076] Among them, in order to further ensure the operability of the connection between the fixing frame 180 and the bottom shell 120 through the first fastener 181; the panel 130 is connected to the opening side of the assembly cavity 121 set in the bottom shell 120 to cover the opening of the assembly cavity 121 and ensure that at least part of the assembly mechanism 170 can be smoothly accommodated in the assembly cavity 121 from the opening of the assembly cavity 121, and the first fastener 181 is configured to connect the bottom shell 120 and the fixing frame 180 from the side away from the opening of the assembly cavity 121.

[0077] Optionally, see Figure 6 and Figure 7 The fixing frame 180 includes a second bottom plate 185 and a second frame 186. The second frame 186 is connected to the second bottom plate 185 and is distributed around the circumference of the second bottom plate 185 to enclose a receiving cavity 187 for accommodating the assembly component 190. A protrusion 188 is provided on the side of the second frame 186 away from the receiving cavity 187. The panel 130 is connected to a first buckle 132, and the first buckle 132 is engaged with the protrusion 188. Such a configuration ensures the stability of the engagement between the panel 130 and the fixing frame 180 on the one hand, and improves the engagement between the panel 130 and the fixing frame 180 on the other hand, which interferes with the assembly of the assembly component 190.

[0078] Optionally, the fixing frame 180 is connected with a positioning column 189, which extends into the assembly cavity 121 of the bottom shell 120 and is connected to the first fastener 181, that is, the first fastener 181 is connected to the first bottom plate 123 of the bottom shell 120 (the first bottom plate 123 is provided with a fastening hole for assembling the first fastener 181) and the fixing frame 180 through the positioning column 189. It is easier to connect the positioning column 189 to the fixing frame 180 than to the bottom shell 120, so the production difficulty can be reduced; and the connection of the first fastener 181 through the positioning column 189 can ensure the connection stability.

[0079] Optionally, the positioning posts 189 are distributed at the periphery of the fixing frame 180, and the positioning posts 189 are also distributed close to the periphery of the panel 130. This arrangement can further ensure the connection strength.

[0080] Optionally, the fixing frame 180 and the positioning column 189 are integrally formed. This arrangement reduces the production process and is conducive to improving efficiency.

[0081] Of course, in other embodiments, the positioning column 189 may also be bonded to the fixing frame 180 , etc., which will not be described in detail here.

[0082] Optionally, the positioning posts 189 are connected to both the second frame 186 and the second bottom plate 185, and the positioning posts 189 are distributed on a side of the second frame 186 facing the accommodating cavity 187. In this way, the stability of the positioning posts 189 connected to the fixing frame 180 can be ensured.

[0083] Of course, in other embodiments, the positioning column 189 may be connected only to the second frame 186 or the second bottom plate 185 .

[0084] In order to ensure the stability of the panel 130 connected to the bottom shell 120 and to ensure the ease of operation of the panel 130 connected to the bottom shell 120; please refer to Figure 3 and Figure 6 The first bottom plate 123 of the bottom case 120 and the panel 130 are connected from a side away from the opening of the assembly cavity 121 by using a third fastener 133 .

[0085] The first fastener 181 and the third fastener 133 both include but are not limited to screws or bolts.

[0086] The above description is about the similar structural parts of the front lock 100 and the rear lock 300. The front lock 100 and the rear lock 300 will be described in detail below with respect to the differences between the front lock 100 and the rear lock 300.

[0087] The assembly mechanism 170 of the front lock 100 is a clutch assembly; Figure 4 and Figure 7The assembly mechanism 170 further includes a driving member 210 and a positioning pin 220. The driving member 210 is assembled on the fixing frame 180. The positioning pin 220 is movably arranged on the assembly component 190 and can be connected or separated from the lock body by transmission. The driving member 210 and the positioning pin 220 are in transmission cooperation, and are used to drive the positioning pin 220 to move relative to the assembly component 190 to be connected to the lock body by transmission, so that the assembly component 190 is connected to the lock body (i.e., the lock tongue) by transmission through the positioning pin 220. In this way, after the user enters a password, swipes a card, or recognizes a fingerprint through the front lock 100, the driving member 210 drives the positioning pin 220 to move to be connected to the lock body by transmission, that is, the positioning pin 220 realizes the transmission connection between the assembly component 190 and the lock body, and the handle 160 realizes the transmission connection with the lock body through the assembly component 190, so that the handle 160 can be pressed or pulled to unlock the lock body.

[0088] It should be noted that the lock body also includes a drive shaft 193, which is transmission-connected to the lock tongue. The drive shaft 193 is connected to the assembly component 190 and can be connected to or separated from the positioning pin 220; when the driving member 210 drives the positioning pin 220 to connect with the drive shaft 193, the assembly component 190 realizes a transmission connection with the lock tongue through the positioning pin 220 and the drive shaft 193, that is, the handle 160 realizes a transmission connection with the lock tongue through the assembly component 190; when the driving member 210 drives the positioning pin 220 to separate from the drive shaft 193, the transmission connection between the assembly component 190 and the lock tongue is disconnected, that is, the transmission connection between the handle 160 and the lock tongue is disconnected through the assembly component 190.

[0089] The transmission connection between the drive shaft 193 and the lock tongue is similar to the related art and will not be described in detail here.

The second cover body 1912 is provided with a slide groove 1913. The positioning pin 220 can be slidably inserted into the slide groove 1913, and the positioning pin 220 can be extended and retracted from the notch in the length extension direction of the slide groove 1913. The first cover body 1911 is connected to the other side of the second cover body 1912 to prevent the positioning pin 220 from falling out of the slide groove 1913, and the first cover body 1911 is provided with a first plug hole 1914. One end of the drive shaft 193 is connected to the lock tongue for transmission, and the other end A first rib 1932 is connected, and a second socket 1931 is provided on the drive shaft 193; the drive shaft 193 is inserted into the first socket 1914 so that the first rib 1932 is located between the first cover body 1911 and the second cover body 1912, and the first rib 1932 can abut against the first cover body 1911 to prevent the drive shaft 193 from escaping from the first socket 1914; the positioning pin 220 can be connected or separated from the second socket 1931 under the drive of the driving member 210, wherein when the positioning pin 220 is connected to the second socket 1931, the assembly component 190 is connected to the drive shaft 193 in transmission, and when the positioning pin 220 is separated from the second socket 1931, the transmission connection between the assembly component 190 and the drive shaft 193 is disconnected. When assembling the positioning pin 220 and the drive shaft 193, the positioning pin 220 can be first inserted into the slide groove 1913, and the drive shaft 193 can be inserted into the first hole 1914, and then the first cover body 1911 and the second cover body 1912 are connected, ensuring the ease of assembly and connection of the drive shaft 193 and the positioning pin 220 to the assembly component 190.

[0091] Furthermore, the outer periphery of the positioning pin 220 is connected with a second rib 221 , and the groove wall of the slide groove 1913 is connected with a third rib 1915 . The second rib 221 can abut against the third rib 1915 to prevent the positioning pin 220 from escaping from the notch set in the length extension direction of the slide groove 1913 .

[0092] The connection method between the first cover body 1911 and the second cover body 1912 includes but is not limited to connection with fasteners such as bolts and bonding.

[0093] Optionally, the driving member 210 includes a motor 211 and a driving plate 212 that is transmission-connected to the motor 211. The driving plate 212 is roughly arc-shaped, and its arc-shaped convex surface is transmission-connected to the output shaft of the motor 211, and the arc-shaped convex surface is transmission-matched with the positioning pin 220. The driving plate 212 is set to be arc-shaped so that its shape is roughly adapted to the assembly component 190, so as to ensure that the driving plate 212 can reliably push the positioning pin 220 to be transmission-connected with the drive shaft 193 while effectively saving space inside the front lock 100.

[0094] Of course, in other embodiments, the driving member 210 may only include the motor 211, and the output shaft of the motor 211 is directly in driving cooperation with the positioning pin 220.

[0095] Optionally, there is no fixed connection between the driving plate 212 and the positioning pin 220 in driving cooperation. That is, when the output shaft of the motor 211 rotates forward and drives the driving plate 212 to move toward the direction close to the positioning pin 220, the driving plate 212 can drive the positioning pin 220 to move to be inserted and cooperated with the driving shaft 193. When the output shaft of the motor 211 rotates reversely and drives the driving plate 212 to move away from the positioning pin 220, in order to ensure that the positioning pin 220 can be reliably reset to be separated from the driving shaft 193 and disconnect the transmission connection between the handle 160 and the lock tongue; the assembling mechanism 170 further includes a second elastic member, and the second elastic member is connected between the assembling component 190 and the positioning pin 220 and is used to drive the positioning pin 220 to reset to be separated from the lock body, so as to disconnect the transmission connection between the assembling component 190 and the lock body.

[0096] When the user inputs the correct password, swipes the card, or uses fingerprint, the motor 211 drives the driving plate 212 to drive the positioning pin 220 to move to be inserted into the driving shaft 193. At this time, the handle 160 realizes the transmission connection with the lock tongue of the lock body through the assembling component 190 and the driving shaft 193. When the user pulls or presses the handle 160, the lock tongue can be driven to retract to realize unlocking. When the unlocking is completed, the motor 211 drives the driving plate 212 to move away from the positioning pin 220. The positioning pin 220 can be reset to be separated from the driving shaft 193 under the action of the second elastic member, and the handle 160 is no longer in transmission connection with the lock tongue, and the lock tongue can be used to lock again.

[0097] It should be noted that after the lock tongue retracts to complete unlocking, it can automatically reset and lock again. The method and principle of the lock tongue resetting and locking are similar to those in the related art and will not be elaborated here.

[0098] Optionally, the second elastic member (not shown in the figure) is sleeved on the positioning pin 220. One end of the second elastic member is connected to the second rib 221, and the other end of the second elastic member is connected to the second cover body 1912. Sleeving the second elastic member on the positioning pin 220 ensures the stability and reliability of the second elastic member. When the positioning pin 220 is inserted into the driving shaft 193, the second elastic member can be reliably compressed to utilize the compressed second elastic member to reliably drive the positioning pin 220 to reset.

[0099] The connection manner between the second elastic member and the second rib 221 and the connection manner between the second elastic member and the second cover body 1912 include but are not limited to abutting, clamping, and bonding.

[0100] It should be understood that in other embodiments, when the positioning pin 220 is inserted into the drive shaft 193, the second elastic member can also be stretched so that when the positioning pin 220 needs to be reset, the stretched second elastic member is used to drive the positioning pin 220 to reset.

[0101] The second elastic member includes but is not limited to springs, elastic rubber sleeves, and torsion springs.

[0102] Optionally, please refer to Figure 10 , the handle 160 is configured to be inserted and cooperated with the assembly component 190; specifically, the handle 160 can be inserted and cooperated with the assembly shaft 194 to realize the transmission connection or separation with the lock tongue through the assembly shaft 194, the second cover 1912, the first cover 1911, and the drive shaft 193. The insertion and cooperation realize the quick installation structure of the handle 160 and the assembly component 190, which is beneficial to improving the assembly efficiency of the front lock 100.

[0103] Furthermore, please refer to Figure 6 and Figure 10 , the handle 160 is provided with a third jack 162, and one end of the assembly shaft 194 away from the second cover 1912 is inserted into the third jack 162.

[0104] Of course, in other embodiments, the assembly shaft 194 is provided with a third jack 162, and the handle 160 is inserted into the third jack 162.

[0105] In order to further ensure that when the handle 160 rotates relative to the panel 130 under the action of an external force, it can reliably drive the assembly component 190 to rotate synchronously; please refer to Figure 6 , the inner wall of the third jack 162 is provided with a positioning groove 163, and the assembly shaft 194 is connected with a positioning rib 195. The positioning rib 195 is inserted and cooperated with the positioning groove 163 so that there is no relative rotation between the handle 160 and the assembly shaft 194, that is, it is ensured that the handle 160 can stably drive the assembly component 190 to rotate.

[0106] Of course, in other embodiments, the inner wall of the third jack 162 is connected with a positioning rib 195, the assembly shaft 194 is provided with a positioning groove 163, and the positioning rib 195 is inserted and cooperated with the positioning groove 163.

[0107] To improve the connection stability between the handle 160 and the assembly component 190, after the handle 160 and the assembly component 190 are inserted, they are connected by a second fastener 161.

[0108] Optionally, the assembly shaft 194 is provided with an avoidance hole, the avoidance hole penetrates through the second cover 1912, and the second fastener 161 extends into the avoidance hole and then connects the assembly shaft 194 and the handle 160. In this way, the second fastener 161 can be covered up to reduce the exposed fasteners.

[0109] The second fastener 161 includes, but is not limited to, bolts and screws.

[0110] Optionally, referring to Figure 5 , the panel 130 is provided with a first assembly hole 131. Referring to Figure 7 , the fixing bracket 180 is provided with a second assembly hole 182. Specifically, the second assembly hole 182 is provided in the second bottom plate 185, and the first assembly hole 131 communicates with the second assembly hole 182; the assembly component 190 passes through the second assembly hole 182 and the first assembly hole 131. Specifically, after the assembly shaft 194 passes through the second assembly hole 182 and the first assembly hole 131 in sequence, it is inserted and matched with the handle 160 and connected to the second fastener 161.

[0111] Of course, in other embodiments, it may also be that the handle 160 passes through the first assembly hole 131 and the second assembly hole 182 in sequence and then is inserted and matched with the assembly shaft 194. Or, in other embodiments, the handle 160 passes through the first assembly hole 131, the assembly shaft 194 is inserted into the second assembly hole 182, and the handle 160 is inserted and connected to the assembly shaft 194.

[0112] After pressing or pulling the handle 160 to retract the lock tongue to unlock, it is necessary to reset the handle 160 to the position before it is pressed or pulled; referring to Figure 4 , Figure 7 and Figure 10 , to ensure the reliability of the reset of the handle 160, the assembly mechanism 170 further includes a first elastic member 200. The first elastic member 200 is arranged on the fixing bracket 180 and is configured to be elastically matched with the assembly component 190 to drive the handle 160 to reset by means of the assembly component 190. Among them, when the handle 160 is pressed or pulled, the assembly component 190 moves with the handle 160 and can cause the first elastic member 200 to undergo elastic deformation; after unlocking is completed through the handle 160, the user releases the handle 160, and the first elastic member 200 can recover under its own elastic action and drive the assembly component 190 and the handle 160 to reset together.

[0113] Optionally, the first elastic member 200 is a torsion spring; referring to Figure 7 and Figure 11, the assembly component 190 includes a fitting 191, a first abutting member 1921 and a second abutting member 1922 connected to the fitting 191. The fitting 191 is rotatably assembled to the fixing bracket 180. Specifically, the first abutting member 1921 and the second abutting member 1922 are connected to the second cover 1912. The second cover 1912 is rotatably assembled to the fixing bracket 180 through a fitting shaft 194 inserted into the second assembly hole 182. The first abutting member 1921 is configured to abut against the first torsion arm of the torsion spring, and the second abutting member 1922 is configured to abut against the second torsion arm of the torsion spring. When the handle 160 rotates relative to the panel 130 under the action of an external force and drives the assembly component 190 to rotate, the first elastic member 200 undergoes elastic deformation under the action of the first abutting member 1921 or the second abutting member 1922. That is, when the handle 160 is no longer under the action of an external force, the first elastic member 200 that elastically returns can drive the assembly component 190 and the handle 160 to reset.

[0114] Optionally, the first abutting member 1921 is detachably connected to the fitting 191. Specifically, the first abutting member 1921 is detachably connected to the second cover 1912. Exemplarily, the first abutting member 1921 is a fastener such as a bolt detachably connected to the second cover 1912. When the first abutting member 1921 is separated from the fitting 191, the fitting 191 can rotate relative to the fixing bracket 180 to drive the handle 160 to rotate synchronously with the fitting 191 and move the second abutting member 1922 to abut against the first torsion arm of the torsion spring. Moreover, after the fitting 191 and the handle 160 rotate, the first abutting member 1921 can be connected to the fitting 191 again and abut against the second torsion arm of the torsion spring. In this way, the commutation of the orientation of the handle 160 can be realized. For example, the handle 160 originally facing the right can be rotated with the fitting 191 to face the left, that is, the lock can be adapted to doors with different opening directions.

[0115] It should be understood that in other embodiments, the second abutting member 1922 is also configured to be detachably connected to the second cover 1912; or, both the first abutting member 1921 and the second abutting member 1922 are non-detachably connected to the second cover 1912.

[0116] In other embodiments, at least one of the first abutting member 1921 and the second abutting member 1922 can also be connected to the first cover 1911.

[0117] To improve the stability of the first elastic member 200 disposed on the fixing bracket 180; please refer to Figure 7 , the fixing bracket 180 is connected with a boss 183. Specifically, the boss 183 is connected to the second bottom plate 185, and the boss 183 is distributed on the outer periphery of the second assembly hole 182. The torsion spring as the first elastic member 200 is sleeved on the boss 183.

[0118] Optionally, the fixing bracket 180 is further connected with two limiting bosses 184 which are circumferentially spaced along the second assembly hole 182; one of the limiting bosses 184 abuts against the first torsion arm of the torsion spring of the first elastic member 200, and the other limiting boss 184 abuts against the second torsion arm of the torsion spring. In this way, the first elastic member 200 can be prevented from rotating around the second jack 1931, that is, the stability of the first elastic member 200 assembled on the fixing bracket 180 can be improved, and further the reliability of resetting the handle 160 and the assembly component 190 by using the first elastic member 200 can be ensured.

[0119] It should be noted that when the handle 160 drives the assembly component 190 to rotate, the positioning pin 220 assembled on the assembly component 190 will rotate together with the assembly component 190; therefore, by matching the arc concave surface of the driving plate 212 with the positioning pin 220, the positioning pin 220 can slide on the surface of the driving plate 212, so as to improve the problem that the driving plate 212 interferes with the rotation of the positioning pin 220, and ensure that the assembly component 190 and the handle 160 can rotate smoothly.

[0120] Optionally, the front lock 100 further includes electronic components, please refer to Figure 3 , for example: the front main board 231 and the power taking board 232. The front main board 231 and the power taking board 232 are both assembled on the panel 130 and located on the side of the panel 130 facing the bottom case 120, and can be assembled on the bottom case 120 together with the panel 130. In this way, the front main board 231 and the power taking board 232 are both modularly assembled with the panel 130, improving the assembly efficiency and reducing the assembly difficulty.

[0121] Optionally, the ways of connecting the front main board 231 and the power taking board 232 to the panel 130 include but are not limited to bonding and clamping.

[0122] Optionally, the front main board 231 is used to implement password input, fingerprint recognition and card swiping to unlock. The front main board 231 is assembled at the upper end of the panel 130, so as to facilitate the user to input the password, recognize the fingerprint and swipe the card to unlock at the corresponding position of the front main board 231, ensuring the convenience of using the lock; the power taking board 232 is electrically connected to the front main board 231 and the motor 211, and is used for taking power and supplying power to the front main board 231 and the motor 211. In order to make full use of the assembly space of the panel 130, the power taking board 232 is connected to the lower end of the panel 130, and the assembly mechanism 170 is located between the front main board 231 and the power taking board 232.

[0123] Of course, in other embodiments, the assembly positions of the front main board 231 and the power taking board 232 can also be: the front main board 231 is arranged at the lower end of the panel 130, and the power taking board 232 is arranged at the upper end of the panel 130.

[0124] In other embodiments, the front main board 231 may only include a password input function and a card swiping function; the front lock 100 also includes a fingerprint recognition module, and the fingerprint recognition module may be assembled on the handle 160 .

[0125] Optionally, the electronic component further includes an anti-dismantling switch 233 , such as a forced dismantling alarm, etc. The anti-dismantling switch 233 is connected to the power board 232 , and can be assembled on the panel 130 together with the power board 232 .

[0126] Of course, the anti-dismantling switch 233 is not necessary, and in other implementations, the anti-dismantling switch 233 may not be configured.

[0127] Please refer to Figure 2 and Figure 12 The assembly mechanism 170 of the rear lock 300 is a common assembly structure, that is, it does not have a clutch function. Of course, in other embodiments, the assembly mechanism 170 of the rear lock 300 can also be configured as a clutch module, such as a child lock structure, so as to use the clutch module to realize the transmission connection or separation between the handle 160 of the rear lock 300 and the lock tongue, thereby helping to improve the problem of accidental door opening.

[0128] The differences between the rear lock 300 and the front lock 100 will be described in detail below, and the similar structures of the rear lock 300 and the front lock 100 will not be described in detail again.

[0129] The assembly mechanism 170 includes a fixing frame 180, a first elastic member 200 and an assembly member 191. The fixing frame 180 is connected to the panel 130. The first elastic member 200 is arranged on the fixing frame 180 and can be elastically matched with the assembly member 191. The handle 160 passes through the first assembly hole 131 of the panel 130 and the second assembly hole 182 of the fixing frame 180 in sequence, and is connected to the assembly member 191. The assembly member 191 is in transmission connection with the lock tongue. In this way, when the handle 160 is pressed or pulled by an external force, the assembly member 191 can be driven to rotate, and the first elastic member 200 can be elastically deformed, and the assembly member 191 can drive the lock tongue to retract to achieve unlocking. When the external force on the handle 160 is removed, the assembly member 191 can be reset under the elastic action of the first elastic member 200, and drive the handle 160 to reset, and the lock tongue can also be reset to the extended state.

[0130] Of course, in other embodiments, the connection method of the handle 160 and the assembly part 191 may also be: the assembly part 191 passes through the second assembly hole 182 and the first assembly hole 131 in sequence, and then is connected to the handle 160. Alternatively, in other embodiments, the connection method of the handle 160 and the assembly part 191 may also be: the handle 160 is inserted into the first assembly hole 131, and the assembly part 191 is inserted into the second assembly hole 182, and then the handle 160 and the assembly part 191 are connected.

[0131] It should be noted that the connection method of the fixing bracket 180 to the panel 130, the setting method of the first elastic member 200 on the fixing bracket 180, and the elastic cooperation method between the fitting 191 and the first elastic member 200 can all refer to the front lock 100, which will not be elaborated here.

[0132] It should also be noted that the method and principle of the locking tongue resetting and extending and locking are similar to those in the related art, which will not be elaborated here.

[0133] Optionally, the fitting 191 of the rear lock 300 can be of a plate-like structure; the fitting 191 and the handle 160 are connected by a second fastener 161. In this way, the stability of the connection between the fitting 191 and the handle 160 can be ensured, and the structure of the fitting 191 can be simplified.

[0134] The panel 130 of the rear lock 300 is also provided with a battery compartment 310. The opening of the battery compartment 310 faces away from the bottom case 120, and the rear lock 300 further includes a lid 311. The battery compartment 310 is used for installing a battery, and the lid 311 is detachably connected to the panel 130. By using the lid 311 connected to the panel 130 to block the battery compartment 310, the reliability of the battery assembled in the battery compartment 310 can be ensured, or the lid 311 can be used to open the battery compartment 310 to facilitate the installation and removal of the battery.

[0135] The connection method between the lid 311 and the panel 130 includes but is not limited to snap connection and connection by fasteners such as bolts.

[0136] The electronic components of the rear lock 300 include a circuit board 313. The circuit board 313 is connected to the panel 130 and is located on the side of the panel 130 facing the bottom case 120, and can be assembled to the bottom box synchronously with the panel 130. In this way, modular assembly is achieved, and the assembly efficiency is improved.

[0137] The connection method between the circuit board 313 and the panel 130 includes but is not limited to connection by fasteners such as bolts and snap connection.

[0138] It should be noted that the circuit board 313 is electrically connected to the battery assembled in the battery compartment 310, and the circuit board 313 can be electrically connected to the power take-off board 232, so that the power take-off board 232 can obtain power from the battery in the battery compartment 310 through the circuit board 313.

[0139] Optionally, the rear lock 300 further includes an anti-lock component 312 provided on the panel 130. The anti-lock component 312 is in transmission connection with the anti-lock bolt of the lock body, so that the anti-lock component 312 rotated by an external force can drive the anti-lock bolt to extend or retract. Among them, the structure of the anti-lock component 312, the connection method to the panel 130, and the transmission cooperation method between the anti-lock component 312 and the anti-lock bolt are all similar to those in the related art, which will not be elaborated here.

[0140] In summary, the handles 160 of the front lock 100 and the rear lock 300 of the lock of the present invention are fixedly connected to the bottom case 120 through the assembly components 190 and the fixing brackets 180, so as to ensure that the fixing points and force-bearing points of the handle 160 are on the bottom case 120, thereby improving the tensile strength of the handle 160.

[0141] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
