Description

Technical Field

[0001] This application relates to the field of security technology, and in particular to a lock body and an interior door equipped with the lock body. Background Technology

[0002] In real life, smart door locks can be opened electronically or mechanically.

[0003] In the process of developing the existing technology, the inventors discovered that:

[0004] When the mechanical key is stolen or the electronic information is copied by an unauthorized user, the unauthorized user can open the smart lock, posing a security risk.

[0005] Therefore, a highly secure technical solution is needed. Summary of the Invention

[0006] This application provides a technical solution to address the technical problem of low security.

[0007] The lock body provided in this application is characterized by comprising:

[0008] Handle assembly, used for unlocking operations;

[0009] The clutch assembly selectively disengages or transmits the operation of the handle assembly;

[0010] The transmission assembly engages with and is driven by the handle assembly;

[0011] The link component slides into the transmission component;

[0012] The latch component works in conjunction with the link component.

[0013] The lock body also includes a super locking mechanism;

[0014] Super-locking mechanisms include:

[0015] Super locking bolt;

[0016] A sliding plate that is linked to the super-locking bolt, the sliding plate having a first sliding groove;

[0017] A super-locking assembly is mounted on a sliding plate and slides within a first sliding groove, having a first state that prevents the bolt assembly from retracting and a second state that facilitates the retraction of the bolt assembly.

[0018] The actuating element moves the sliding plate to adjust its position relative to the super-locking assembly, forming a first state that prevents the bolt assembly from retracting and a second state that facilitates the retraction of the bolt assembly.

[0019] Furthermore, in one embodiment provided in this application, the super-locking component includes:

[0020] Swing board;

[0021] A guide post that passes through the swing plate and slides within the first sliding groove;

[0022] A curved spring is fitted onto the guide post and has two compression legs, one of which abuts against the swing plate and the other compression leg is confined.

[0023] In the first state, the guide post is located in the first position in the first sliding groove, the two compression legs are in the open state, the swing plate opens under the action of the compression legs, and stays in the retraction stroke of the lock tongue assembly, thus hindering the retraction of the lock tongue assembly.

[0024] In the second state, the guide post is located in the second position within the first sliding groove. The first sliding groove compresses the guide post, causing the two compression legs of the spring to retract. The swing plate retracts and closes with the compression legs, leaving the retraction stroke of the latch assembly, so that the latch assembly can retract.

[0025] Furthermore, in one embodiment provided in this application, the actuating element includes an actuating shaft and an actuating lever;

[0026] The main body of the shaft hole of the actuating shaft is square and has serrations inside.

[0027] Furthermore, in one embodiment provided in this application, the actuating element includes an actuating shaft and an actuating lever;

[0028] The main body of the shaft hole of the actuating shaft is square, and the four sides of the square extend outward to form cross grooves, forming a nested shape of square and cross grooves.

[0029] Furthermore, in one embodiment provided in this application, the lock body further includes an anti-impact force locking mechanism;

[0030] The impact-resistant locking mechanism includes:

[0031] The main body of the oblique tongue includes an oblique tongue portion and a guide portion extending integrally from the oblique tongue portion;

[0032] A flip tongue that fits into the main body of the oblique tongue and rotates relative to the main body of the oblique tongue;

[0033] The first elastic element that abuts against the main body of the oblique tongue;

[0034] When the tongue body is subjected to an instantaneous impact force, the impact force is transmitted to the first elastic element, and the tongue body is reset under the action of the first elastic element after the instantaneous impact force is eliminated.

[0035] When the oblique tongue body is subjected to continuous prying force, the oblique tongue body and the flipping tongue cross to form a force-bearing part and move together until the flipping tongue moves to the preset blocking position.

[0036] When the latch body is in normal unlocking operation, the latch body and the flipping tongue work together until the preset blocking position, and the flipping tongue flips and closes relative to the latch body. The latch body and the flipping tongue pass the preset blocking position to the preset open position.

[0038] A blocking component that blocks the oblique tongue body and the flipping tongue at a preset blocking position;

[0039] A state tongue assembly that limits the movement of the blocking component;

[0040] A second elastic element for resetting the state tongue assembly;

[0041] The blocking member has a channel inside. The channel size is larger than the external size of the guide part of the tongue body and smaller than the size of the tongue part, so that the guide part can pass through the channel but the tongue part cannot pass through the channel.

[0042] When the state tongue assembly is subjected to continuous prying force, the state tongue assembly retracts to release the limit on the blocking part, the blocking part deflects, and the oblique tongue body and the flipping tongue are prevented from moving to the preset blocking position in advance.

[0043] When the state tongue assembly is removed by continuous prying force, the state tongue assembly is reset under the action of the second elastic member and drives the blocking member to reset, so as to provide a channel for the guide part of the oblique tongue body to pass through.

[0044] When the status tongue assembly is in normal unlocking operation, the inclined tongue body and the flip tongue work together to allow the guide part to enter the channel, and the inclined tongue part of the inclined tongue body pushes against the status tongue assembly and continues to retract to the preset open position.

[0045] Furthermore, in one embodiment provided in this application, the state tongue component includes:

[0046] Status tongue;

[0047] A linkage plate fixedly connected to the status tongue;

[0048] The abutment post is installed on the abutment blocking component of the linkage plate.

[0049] Furthermore, in one embodiment provided in this application, the blocking member is provided with a retraction edge extending in the retraction direction of the tongue body and an inclined edge intersecting the retraction edge at an inclination, so that the abutment post drives the blocking member to reset.

[0050] Furthermore, in one embodiment provided in this application, the lock body further includes an electronic lock assembly;

[0051] The lock body has an unlocked state and a locked state;

[0052] When the electronic lock component is in the unlocked state corresponding to the lock body, the electronic lock component abuts against the clutch component, causing the handle component and the transmission component to engage.

[0053] When the electronic lock component is in the locked state corresponding to the lock body, the electronic lock component abuts against the clutch component, causing the handle component and the transmission component to disengage.

[0054] Furthermore, when the electronic lock assembly is in the unlocked state corresponding to the lock body, the minimum distance between the rotation center of the handle assembly and the electronic lock assembly is X;

[0055] When the electronic lock assembly is in the locked state corresponding to the lock body, the minimum distance between the rotation center of the handle assembly and the electronic lock assembly is Y;

[0056] X is less than Y;

[0057] The electronic lock assembly has an arc-shaped sliding part at its end that is slidably connected to the clutch assembly.

[0058] This application also protects an interior door equipped with the aforementioned lock body, wherein the lock body includes a handle assembly for unlocking operations;

[0059] The clutch assembly selectively disengages or transmits the operation of the handle assembly;

[0060] The transmission assembly engages with and is driven by the handle assembly;

[0109] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0110] Please refer to Figures 1 to 5 The lock body 100 disclosed in this application includes:

[0111] Handle assembly 11 is used for unlocking operations;

[0112] The clutch assembly 12 selectively disengages or transmits the operation of the handle assembly 11;

[0113] The transmission assembly 13 engages with and is driven by the handle assembly 11;

[0114] Link component 14 is slidably engaged with transmission component 13;

[0115] Locking tongue component 15 is linked with link component 14;

[0116] Please refer to Figures 3 to 5 The lock body 100 also includes a super locking mechanism;

[0117] Super-locking mechanisms include:

[0118] Super Locking Tongue 161;

[0119] A sliding plate 162 is linked to the super locking bolt 161, and the sliding plate 162 is provided with a first sliding groove;

[0120] A super-locking assembly that is mounted on a sliding plate 162 and slides within a first sliding groove, having a first state that prevents the bolt assembly 15 from retracting and a second state that facilitates the retraction of the bolt assembly 15.

[0121] The actuating element 163 moves the sliding plate 162 so that the sliding plate 162 and the super locking assembly are adjusted to form a first state that prevents the bolt assembly 15 from retracting and a second state that facilitates the retraction of the bolt assembly 15.

[0122] Handle assembly 11 is used for unlocking operations. Handle assembly 11 includes a handle core and a handle sleeve. The handle core provides a rotational center axis. The handle sleeve is used to transmit the user's operating force to the corresponding moving parts of the lock body 100 so as to switch the lock body 100 between an unlocked state and a locked state.

[0123] The clutch assembly 12 selectively disengages or transmits the operation of the handle assembly 11. The clutch assembly 12 includes a spindle 121 and a return spring 122. When the spindle 121 is inserted into the handle sleeve and transmission assembly 13, the handle assembly 11 and transmission assembly 13 are engaged, and the operation of the handle assembly 11 is transmitted. When the spindle 121 moves axially to the position where the handle sleeve and transmission assembly 13 are disengaged, the operation of the handle assembly 11 is disengaged, and transmission to the transmission assembly 13 ceases.

[0124] The transmission assembly 13 includes a first transmission pair 131 coaxial with the handle assembly 11 and a second transmission pair 132 meshing with the first transmission pair 131. The transmission assembly 13 also includes a mechanical gear 133 selectively meshing with the second transmission pair 132.

[0125] The connection between the first transmission pair 131 and the second transmission pair 132, and the connection between the first transmission pair 131 and the handle sleeve, can be considered as the implementation of electronically controlled unlocking and locking. The connection between the mechanical gear 133 and the second transmission pair 132 can be considered as the implementation of mechanical unlocking and locking. The mechanical gear 133 and the mechanical key achieve transmission directly or indirectly through multi-stage transmission.

[0126] The linking component 14 is slidably engaged with the transmission component 13. To improve locking security, in one specific implementation provided in this application, the bolt assembly 15 is distributed in multiple locations or areas. The linking component 14 connects multiple parts of the bolt assembly 15 to achieve synchronized retraction and extension of the entire assembly, thereby enabling the locking and unlocking of the lock body 100.

[0127] Please refer to Figure 3 The latch assembly 15 includes a first main latch group 151, a second main latch group 152, and a third main latch group 153. The linking component 14 connects the first main latch group 151, the second main latch group 152, and the third main latch group 153, enabling them to work together in a synchronized manner for retraction and extension. It is understandable that in some specific implementations, the latch assembly 15 may also include a deadbolt. Alternatively, the deadbolt can be considered as part of the latch assembly 15.

[0128] Super-locking mechanisms include:

[0129] Super Locking Tongue 161;

[0130] A sliding plate 162 is linked to the super locking bolt 161, and the sliding plate 162 is provided with a first sliding groove;

[0131] A super-locking assembly that is mounted on a sliding plate 162 and slides within a first sliding groove, having a first state that prevents the bolt assembly 15 from retracting and a second state that facilitates the retraction of the bolt assembly 15.

[0132] The actuating element 163 moves the sliding plate 162 so that the sliding plate 162 and the super locking assembly are adjusted to form a first state that prevents the bolt assembly 15 from retracting and a second state that facilitates the retraction of the bolt assembly 15.

[0133] The super locking mechanism has a higher level of access control than electronic and mechanical locks. In other words, when the super locking mechanism is engaged, the lock body 100 cannot be opened by either electronic or mechanical means.

[0134] The super-locking bolt 161 includes a cylindrical bolt body and a sliding plate 162 integrally linked with the cylindrical bolt body. The sliding plate 162 is provided with a first sliding groove. The main body of the first sliding groove is strip-shaped. The sliding plate 162 is also provided with a slot that cooperates with the actuating member 163.

[0135] The super-locking assembly is mounted on the sliding plate 162 and slides within the first sliding groove. The super-locking assembly has a first state that prevents the bolt assembly 15 from retracting and a second state that facilitates the retraction of the bolt assembly 15.

[0136] Please refer to Figures 3 to 5 Furthermore, in one embodiment provided in this application, the super-locking component includes:

[0137] Swing board 164;

[0138] Guide post 165 passing through swing plate 164 and sliding in first sliding groove;

[0139] A curved spring is fitted onto the guide post 165 and has two compression legs, one of which abuts against the swing plate 164 and the other compression leg is confined.

[0140] In the first state, the guide post 165 is located in the first position in the first sliding groove, the two compression legs are in the open state, the swing plate 164 opens under the action of the compression legs and stays in the retraction stroke of the locking tongue assembly 15, thus hindering the retraction of the locking tongue assembly 15.

[0141] In the second state, the guide post 165 is located in the second position within the first sliding groove. The first sliding groove presses the guide post 165, causing the two compression legs of the spring to retract. The swing plate 164 retracts and closes away from the return stroke of the latch assembly 15 as the compression legs retract, so that the latch assembly 15 can retract.

[0142] Please refer to Figure 4 The actuating element 163 includes an actuating shaft 1631 and an actuating lever 1632. In one specific implementation provided in this application, the shaft hole of the actuating shaft 1631 is square in shape and has serrations inside. The serrations provide multiple engagement points and increase the lever arm, thereby increasing the torque under the same operating force.

[0143] In another specific implementation provided in this application, the shaft hole of the actuating shaft 1631 is square, and cross grooves extend outward from the middle of the four sides of the square, forming a nested shape of square and cross grooves. This provides another configuration for the actuating member 163, facilitating the setting of the specific shape of the actuating member 163 according to actual conditions and increasing its adaptability.

[0144] Please refer to Figures 3 to 5Furthermore, in one embodiment provided in this application, the lock body 100 also includes an anti-impact force damage locking mechanism;

[0145] The impact-resistant locking mechanism includes:

[0146] The oblique tongue body 171 includes an oblique tongue portion 1711 and a guide portion 1712 integrally extending from the oblique tongue portion 1711;

[0147] A flipping tongue 172 that fits into the oblique tongue body 171 and rotates relative to the oblique tongue body 171;

[0148] The first elastic element 173 abuts against the oblique tongue body 171;

[0149] When the oblique tongue body 171 is subjected to an instantaneous impact force, the impact force of the oblique tongue body 171 is transmitted to the first elastic element 173, and after the instantaneous impact force is eliminated, the oblique tongue body 171 is reset under the action of the first elastic element 173.

[0150] When the oblique tongue body 171 is subjected to continuous prying force, the oblique tongue body 171 and the flipping tongue 172 cross to form a force-bearing part and move together until the flipping tongue 172 moves to the preset blocking position.

[0151] When the latch body 171 is in normal unlocking operation, the latch body 171 and the flipping tongue 172 work together until the preset blocking position, and the flipping tongue 172 flips and closes relative to the latch body 171. The latch body 171 and the flipping tongue 172 pass the preset blocking position to the preset open position.

[0152] The latch body 171 includes a latch portion 1711 and a guide portion 1712 integrally extending from the latch portion 1711. The latch assembly 15 has high rigidity and is prone to failure under strong impact. The latch portion 1711 has an inclined outer surface, which can further be formed by a curved surface. Simultaneously, the latch body 171 can also abut against the first elastic member 173. This greatly reduces the impact force, and after the impact force is eliminated, it extends under the action of the first elastic member 173, thereby improving the security of the lock body 100.

[0153] The guide portion 1712 extends integrally from the oblique tongue portion 1711. The size of the guide portion 1712 is smaller than that of the oblique tongue portion 1711, or more precisely, the width or thickness of the guide portion 1712 is smaller than that of the oblique tongue portion 1711.

[0154] The flip tongue 172 is fitted into the oblique tongue body 171 and rotates relative to the oblique tongue body 171. This rotation is not a circular rotation, but a rotation at a certain angle, or a flip at a certain angle.

[0155] When the tongue body 171 is subjected to an instantaneous impact force, the impact force of the tongue body 171 is transmitted to the first elastic element 173, and after the instantaneous impact force is eliminated, the tongue body 171 is reset under the action of the first elastic element 173.

[0156] When the oblique tongue body 171 is subjected to continuous prying force, the oblique tongue body 171 and the flipping tongue 172 cross to form a force-bearing part and move together until the flipping tongue 172 moves to the preset blocking position. The flipping tongue 172 is further retracted and stopped at the preset blocking position.

[0157] When the latch body 171 is in normal unlocking operation, the latch body 171 and the flipping tongue 172 work together until the preset blocking position, and the flipping tongue 172 flips and closes relative to the latch body 171. The latch body 171 and the flipping tongue 172 pass the preset blocking position to the preset open position.

[0158] In this way, the oblique tongue body 171 and the flipping tongue 172 work together to provide a highly safe solution whether the oblique tongue body 171 is subjected to instantaneous impact or continuous prying force.

[0159] Please refer to Figure 5 Furthermore, in one embodiment provided in this application, the impact-resistant locking mechanism further includes:

[0160] The blocking member 174 blocks the oblique tongue body 171 and the flipping tongue 172 at the preset blocking position;

[0161] A state tongue assembly that limits the blocking element 174;

[0162] The second elastic element 175 resets the state tongue assembly;

[0163] The blocking member 174 has a channel inside. The channel size is larger than the external size of the guide part 1712 of the tongue body 171 and smaller than the size of the tongue part 1711, so that the guide part 1712 can pass through the channel but the tongue part 1711 cannot pass through the channel.

[0164] When the state tongue assembly is subjected to continuous prying force, the state tongue assembly retracts to release the limit on the blocking member 174, and the blocking member 174 deflects, preventing the oblique tongue body 171 and the flipping tongue 172 from moving to the preset blocking position in advance.

[0165] When the state tongue assembly is removed by the continuous prying force, the state tongue assembly is reset under the action of the second elastic member 175 and drives the blocking member 174 to reset, so as to provide a channel for the guide part 1712 of the oblique tongue body 171 to pass through.

[0166] When the status tongue assembly is in normal unlocking operation, the inclined tongue body 171 and the flip tongue 172 work together to cause the guide part 1712 to enter the channel, and the inclined tongue part 1711 of the inclined tongue body 171 pushes against the status tongue assembly and continues to retract to the preset open position.

[0167] The blocking member 174 is an irregularly shaped part. The blocking member 174 includes a first plate-shaped member and a bent plate perpendicular to the first plate-shaped member. The first plate-shaped member and the bent plate form a semi-enclosed channel. The first plate-shaped member is equipped with a mounting post perpendicular to the first plate-shaped member and a curved spring. The curved spring extends with two compression legs, one of which is fixed, and the other end abuts against the blocking member 174.

[0168] The status tongue assembly includes a status tongue 181, a linkage plate 182 fixedly connected to the status tongue 181, and an abutting post 183 disposed on the linkage plate 182 abutting the blocking member 174.

[0169] The state tongue 181 is pointed. The state tongue 181 is fixedly connected to the linkage plate 182. The linkage plate 182 is equipped with a stop post 183. The space defined by the linkage plate 182 and the blocking member 174 allows the guide part 1712 of the oblique tongue body 171 to pass through easily. The blocking member 174 has a channel inside, the size of which is larger than the external size of the guide part 1712 of the oblique tongue body 171 and smaller than the size of the oblique tongue 1711, so that the guide part 1712 can pass through the channel but the oblique tongue 1711 cannot pass through the channel.

[0170] The second elastic element 175 resets the state tongue 181 assembly. The second elastic element 175 is a spring.

[0171] When the status tongue assembly is subjected to continuous prying force, the status tongue assembly retracts to release the limit on the blocking member 174, and the blocking member 174 deflects, preventing the oblique tongue body 171 and the flipping tongue 172 from moving to the preset blocking position in advance.

[0172] When the state tongue assembly is removed by the continuous prying force, the state tongue assembly is reset under the action of the second elastic member 175 and drives the blocking member 174 to reset, so as to provide a channel for the guide part 1712 of the oblique tongue body 171 to pass through.

[0173] When the status tongue assembly is in normal unlocking operation, the inclined tongue body 171 and the flip tongue 172 work together to cause the guide part 1712 to enter the channel, and the inclined tongue part 1711 of the inclined tongue body 171 pushes against the status tongue assembly and continues to retract to the preset open position.

[0174] Furthermore, in a specific embodiment provided in this application, the blocking member 174 is provided with a retraction edge extending in the retraction direction of the tongue body 171 and an inclined edge intersecting the retraction edge at an inclination, so that the abutment post 183 drives the blocking member 174 to reset.

[0175] When the abutment post 183 is reset under the action of the second elastic member 175, the abutment post 183 presses against the blocking member 174, providing the resetting force of the blocking member 174.

[0176] Furthermore, in one specific embodiment provided in this application, the lock body 100 further includes an electronic lock assembly 19;

[0177] The lock body 100 has an unlocked state and a locked state;

[0178] When the electronic lock assembly 19 is in the unlocked state corresponding to the lock body 100, the electronic lock assembly 19 abuts against the clutch assembly 12, causing the handle assembly 11 and the transmission assembly 13 to engage.

[0179] When the electronic lock assembly 19 is in the locked state corresponding to the lock body 100, the electronic lock assembly 19 abuts against the clutch assembly 12, causing the handle assembly 11 and the transmission assembly 13 to disengage.

[0180] Furthermore, in a specific embodiment provided in this application, when the electronic lock assembly 19 corresponds to the unlocked state of the lock body 100, the minimum distance between the rotation center of the handle assembly 11 and the electronic lock assembly 19 is X;

[0181] When the electronic lock assembly 19 is in the locked state corresponding to the lock body, the minimum distance between the rotation center of the handle assembly 11 and the electronic lock assembly 19 is Y;

[0182] X is less than Y;

[0183] The electronic lock assembly 19 has an arc-shaped sliding part at its end that is slidably connected to the clutch assembly 12.

[0184] When the electronic lock assembly 19 is in the unlocked state, its end has an arc-shaped sliding part that slides with the clutch assembly 12, causing the spindle 121 to move axially inward, passing through the handle sleeve and the transmission assembly 13. In this way, the operating force applied by the handle is transmitted within the lock body 100. However, when the electronic lock assembly 19 corresponds to the locked state of the lock body 100, although it abuts against the clutch assembly 12, the handle sleeve and transmission assembly 13 disengage. The operating force applied by the handle causes the handle sleeve to spin freely, preventing the operating force from being transmitted to the transmission assembly 13.

[0185] This application also provides an interior door equipped with a lock body 100, the lock body 100 comprising:

[0186] Handle assembly 11 is used for unlocking operations;

[0187] The clutch assembly 12 selectively disengages or transmits the operation of the handle assembly 11;

[0188] The transmission assembly 13 engages with and is driven by the handle assembly 11;

[0189] Link component 14 is slidably engaged with transmission component 13;

[0190] Locking tongue component 15 is linked with link component 14;

[0191] The lock body 100 also includes a super locking mechanism;

[0192] Super-locking mechanisms include:

[0193] Super Locking Tongue 161;

[0194] A sliding plate 162 is linked to the super locking bolt 161, and the sliding plate 162 is provided with a first sliding groove;

[0195] A super-locking assembly that is mounted on a sliding plate 162 and slides within a first sliding groove, having a first state that prevents the bolt assembly 15 from retracting and a second state that facilitates the retraction of the bolt assembly 15.

[0196] The actuating element 163 moves the sliding plate 162 so that the sliding plate 162 and the super locking assembly are adjusted to form a first state that prevents the bolt assembly 15 from retracting and a second state that facilitates the retraction of the bolt assembly 15.

[0197] Furthermore, in one specific embodiment provided in this application, the super-locking component includes:

[0198] Swing board 164;

[0199] Guide post 165 passing through swing plate 164 and sliding in first sliding groove;

[0200] A curved spring is fitted onto the guide post 165 and has two compression legs, one of which abuts against the swing plate 164 and the other compression leg is confined.

[0201] In the first state, the guide post 165 is located in the first position in the first sliding groove, the two compression legs are in the open state, the swing plate 164 opens under the action of the compression legs and stays in the retraction stroke of the locking tongue assembly 15, thus hindering the retraction of the locking tongue assembly 15.

[0202] In the second state, the guide post 165 is located in the second position within the first sliding groove. The first sliding groove presses the guide post 165, causing the two compression legs of the spring to retract. The swing plate 164 retracts and closes away from the return stroke of the latch assembly 15 as the compression legs retract, so that the latch assembly 15 can retract.

[0203] Furthermore, in one specific embodiment provided in this application, the actuating element 163 includes an actuating shaft 1631 and an actuating lever 1632;

[0204] The shaft hole of the actuating shaft 1631 is square in shape and has serrations inside.

[0205] Furthermore, in one specific embodiment provided in this application, the actuating element 163 includes an actuating shaft 1631 and an actuating lever 1632;

[0206] The shaft hole of the actuating shaft 1631 is square in shape, and the four sides of the square extend outward to form cross grooves, forming a nested shape of square and cross grooves.

[0207] Furthermore, in one specific embodiment provided in this application, the lock body 100 further includes an anti-impact force damage locking mechanism;

[0208] The impact-resistant locking mechanism includes:

[0209] The oblique tongue body 171 includes an oblique tongue portion 1711 and a guide portion 1712 integrally extending from the oblique tongue portion 1711;

[0210] A flipping tongue 172 that fits into the oblique tongue body 171 and rotates relative to the oblique tongue body 171;

[0211] The first elastic element 173 abuts against the oblique tongue body 171;

[0212] When the oblique tongue body 171 is subjected to an instantaneous impact force, the impact force of the oblique tongue body 171 is transmitted to the first elastic element 173, and after the instantaneous impact force is eliminated, the oblique tongue body 171 is reset under the action of the first elastic element 173.

[0213] When the oblique tongue body 171 is subjected to continuous prying force, the oblique tongue body 171 and the flipping tongue 172 cross to form a force-bearing part and move together until the flipping tongue 172 moves to the preset blocking position.

[0214] When the latch body 171 is in normal unlocking operation, the latch body 171 and the flipping tongue 172 work together until the preset blocking position, and the flipping tongue 172 flips and closes relative to the latch body 171. The latch body 171 and the flipping tongue 172 pass the preset blocking position to the preset open position.

[0215] Furthermore, in one specific embodiment provided in this application, the impact-resistant locking mechanism further includes:

[0219] The blocking member 174 has a channel inside. The channel size is larger than the external size of the guide part 1712 of the tongue body 171 and smaller than the size of the tongue part 1711, so that the guide part 1712 can pass through the channel but the tongue part 1711 cannot pass through the channel.

[0220] When the state tongue assembly is subjected to continuous prying force, the state tongue assembly retracts to release the limit on the blocking member 174, and the blocking member 174 deflects, preventing the oblique tongue body 171 and the flipping tongue 172 from moving to the preset blocking position in advance.

[0221] When the state tongue assembly is removed by the continuous prying force, the state tongue assembly is reset under the action of the second elastic member 175 and drives the blocking member 174 to reset, so as to provide a channel for the guide part 1712 of the oblique tongue body 171 to pass through.

[0222] When the status tongue assembly is in normal unlocking operation, the inclined tongue body 171 and the flip tongue 172 work together to cause the guide part 1712 to enter the channel, and the inclined tongue part 1711 of the inclined tongue body 171 pushes against the status tongue assembly and continues to retract to the preset open position.

[0230] When the electronic lock assembly 19 is in the unlocked state corresponding to the lock body 100, the electronic lock assembly 19 abuts against the clutch assembly 12, causing the handle assembly 11 and the transmission assembly 13 to engage.

[0231] When the electronic lock assembly 19 is in the locked state corresponding to the lock body 100, the electronic lock assembly 19 abuts against the clutch assembly 12, causing the handle assembly 11 and the transmission assembly 13 to disengage.

[0232] Furthermore, in a specific embodiment provided in this application, when the electronic lock assembly 19 corresponds to the unlocked state of the lock body 100, the minimum distance between the rotation center of the handle assembly 11 and the electronic lock assembly 19 is X;

[0233] When the electronic lock assembly 19 corresponds to the lock body 100 in the locked state, the minimum distance between the rotation center of the handle assembly 11 and the electronic lock assembly 19 is Y;
