Description

Technical Field

[0001] The utility model relates to the field of locks, in particular to a deadbolt lock. Background Art

[0002] Deadbolt locks are a widely used type of lock. Currently, some deadbolt locks are available on the market, offering both key and electric unlocking (such as fingerprint or password unlocking). These locks typically have a motor for opening and closing the lock. During electric unlocking, the motor drives a shaft, which in turn drives the bolt to extend and retract. In existing deadbolt locks, after the shaft's state changes, the motor's transmission structure can obstruct the shaft. When the user uses the key to open and close the lock again, the shaft drives the transmission structure in the opposite direction, causing the motor to rotate in reverse, shortening its lifespan. Furthermore, this structure can become stuck, rendering the lock inoperable using the key and posing a safety hazard. Utility Model Content

[0003] The purpose of the utility model is to provide a deadlock with a simple and reasonable structure, which can disconnect the linkage between the two after the driving component changes the state of the shaft rod and ensure that the shaft has sufficient rotation space, thereby improving the safety of product use and extending the service life of the product.

[0004] A deadbolt lock, comprising:

[0005] The front panel includes a housing, a battery box detachably connected to the housing, a lock core passing through the housing, and a shaft connected to the lock core;

[0006] a rear panel, disposed opposite to the front panel, the rear panel comprising a knob connected to the shaft; and

[0007] A lock body is provided between the front panel and the rear panel, the lock body including a lock tongue, the shaft passing through the lock body, and the shaft being rotatable to drive the lock tongue to extend and retract;

[0008] In which, the front panel also includes a linkage part and a driving assembly, the linkage part is sleeved on the outer circumference of the shaft rod, the linkage part is provided with a through hole for the shaft rod to pass through, the through hole is provided with two right-angle bosses rotationally symmetrical with its center as the axis, and two fan-shaped clutch grooves are formed between the two right-angle bosses. The driving assembly can drive the linkage part to rotate, and the linkage part drives the shaft rod to rotate through the right-angle boss, or rotates independently relative to the shaft rod through the clutch groove.

[0009] In the above technical solution, the linkage is provided with a right-angled boss, and the drive assembly can drive the linkage to rotate clockwise or counterclockwise. The linkage then drives the shaft to rotate via the right-angled boss, thereby extending or retracting the lock tongue. The linkage is also provided with two fan-shaped clutch slots. When the linkage drives the shaft to rotate, the drive assembly drives the linkage to rotate in the opposite direction. At this time, the linkage avoids the shaft through the clutch slots and rotates independently. At the same time, after the reverse rotation, the clutch slot is located in front of the next rotation of the shaft, thereby providing space for the key to drive the shaft. When the user uses the key to open or close the lock, the shaft can rotate independently relative to the linkage, thereby avoiding driving the drive assembly. On the one hand, this can prevent the drive assembly from blocking the shaft, thereby improving the safety of product use; on the other hand, it can prevent the shaft from driving the drive assembly, thereby extending the service life of the product.

[0010] Furthermore, snap fasteners are symmetrically provided on both sides of the battery box, and the snap fasteners include a bending section, a connecting section, and a snap fastener section connected in sequence, one end of the bending section is connected to the battery box, and the other end is bent parallel to the side of the battery box, the connecting section extends toward the battery box perpendicular to the bending section, and the snap fastener section is connected to the bending section and extends in a direction parallel to the side of the battery box.

[0011] In the above technical solution, the battery box is provided with a snap fastener, which includes a bending section, a connecting section, and a snap fastener section connected in sequence. The snap fastener section is connected to the bending section and extends in a direction parallel to the side of the battery box, so that the snap fastener section can approach the battery box under the action of external force. During installation, the battery box is pushed into the shell, and the two snap fasteners are pressed by fingers to make the snap fastener section approach the battery box. When the battery box slides into place, the pressure is released, and the snap fastener section is reset under the elastic force of the bending section, thereby snapping into contact with the shell. During disassembly, it is only necessary to press the two snap fasteners with your fingers to separate the snap fastener section from the shell, and then pull out the battery box. The operation is simple and convenient, effectively improving the efficiency of battery replacement and enhancing the user experience. The overall structure is simple and reasonable, which is conducive to the miniaturization of the deadbolt volume.

[0012] Furthermore, the right-angle boss includes a first surface and a second surface that are perpendicular to each other, the first surfaces of the two right-angle bosses and the second surfaces of the two right-angle bosses are parallel, and the linkage drives the shaft to rotate forward or reverse through the first surface or the second surface.

[0013] In the above technical solution, the shaft has two states: unlocked and locked. The two states are respectively against the first surface or the second surface. At this time, rotating the linkage can drive the shaft through the first surface or the second surface, thereby switching the shaft from one state to another.

[0014] Furthermore, it also includes a sensing part, which is arranged on the outer periphery of the linkage part. The outer periphery of the linkage part is provided with a first boss, and second bosses are provided on both sides of the first boss. The linkage part can be rotated to make the first boss or the second boss contact the sensing part.

[0015] In the above technical solution, the sensing part can determine the rotation position of the linkage part by sensing the first boss and the second boss. Specifically, in the initial state, the first boss is against the sensing part. When the user performs the unlocking or locking action, the linkage part rotates clockwise or counterclockwise, so that one of the second bosses contacts the sensing part. At this time, the sensing part obtains the first contact signal, and then the linkage part rotates in the opposite direction and resets, so that the first boss contacts the sensing part again. At this time, the sensing part obtains the second contact signal, that is, in each complete unlocking or locking action of the linkage part, the sensing part will obtain two contact signals. The number of contact signals can be used to determine whether the linkage part has rotated into place or whether the unlocking or locking action is completed.

[0016] Furthermore, the angle between the line connecting the first boss and the center of the linkage member and the line connecting the second boss and the center of the linkage member is 90°.

[0017] In the above technical solution, by setting the angle of the line connecting the first boss and the second push and the center of the linkage part, the angle required for the linkage part to rotate each time it is unlocked and locked can be determined, thereby judging whether the action of the linkage part is in place.

[0018] Furthermore, the distance between the planes where the two first surfaces are located, and the distance between the planes where the two second surfaces are located, are equal to the thickness of the shaft and smaller than the width of the shaft.

[0019] In the above technical solution, it can be ensured that the two first surfaces or the two second surfaces can be closely against the surface of the shaft, thereby improving the efficiency and stability of driving the shaft to rotate.

[0020] Furthermore, the driving assembly includes a driving member and a first gear connected to the driving member. A second gear is provided on the outer periphery of the linkage member, and the second gear is meshed with the first gear.

[0021] In the above technical solution, the driving member drives the linkage member to rotate through the cooperation of the first gear and the second gear, and the structure is simple and reasonable.

[0022] Furthermore, the battery box includes a plurality of slots, and elastic conductive parts and conductive sheets are respectively provided at both ends of the slots.

[0023] In the above technical solution, the battery installed in the battery box can be connected through the elastic conductive member and the conductive sheet, thereby supplying power to the lock body.

[0024] Furthermore, a conductive contact is provided at one end of the battery box, the conductive contact is electrically connected to the elastic conductive member and the conductive sheet, and a conductive spring for contacting the conductive contact is provided in the shell.

[0025] In the above technical solution, when the battery box is inserted into the cavity, the conductive contacts can contact the conductive springs, thereby connecting the battery and the circuit in the lock body, thereby realizing rapid disassembly and assembly of the battery box.

[0026] Furthermore, the conductive contacts are in at least two groups.

[0027] In the above technical solution, the conductive contacts are provided in at least two groups. When one group of the conductive contacts fails or has a poor connection, the lock body can be powered through the other group of conductive contacts, thereby improving the reliability of the connection.

[0028] Compared with the prior art, the present invention has the following beneficial effects: the linkage member is provided with a right-angled boss, and the drive assembly can drive the linkage member to rotate clockwise or counterclockwise. The linkage member then drives the shaft to rotate via the right-angled boss, thereby extending or retracting the lock tongue. The linkage member is also provided with two fan-shaped clutch grooves. When the linkage member drives the shaft to rotate, the drive assembly drives the linkage member to rotate in the opposite direction. At this time, the linkage member avoids the shaft through the clutch grooves and rotates independently. At the same time, after the reverse rotation, the clutch groove is located in front of the next rotation of the shaft, thereby providing space for the key to drive the shaft. When the user uses the key to open or close the lock, the shaft can rotate independently relative to the linkage member, thereby avoiding driving the drive assembly. On the one hand, this can prevent the drive assembly from blocking the shaft, thereby improving the safety of the product; on the other hand, it can prevent the shaft from driving the drive assembly, thereby extending the service life of the product.

DETAILED DESCRIPTION

[0038] To facilitate understanding of the present invention, the present invention will be described more fully below with reference to the accompanying drawings. The accompanying drawings illustrate preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein.

[0039] Please refer to Figures 1 to 4 In a preferred embodiment, the deadbolt lock of the present invention primarily comprises a front panel 1, a rear panel 2, and a lock body 3. The front panel 1 comprises a housing 11, a battery compartment 12 detachably connected to the housing 11, a lock cylinder 13 extending through the housing 11, and a shaft 14 connected to the lock cylinder 13. The rear panel 2 is disposed opposite the front panel 1 and includes a knob connected to the shaft 14. The lock body 3 is disposed between the front and rear panels 1 and includes a lock tongue 31. The shaft 14 extends through the lock body 3 and is rotatable to extend and retract the lock tongue 31.

[0040] The front panel 1 also includes a linkage 15 and a drive assembly 16. The linkage 15 is sleeved on the outer periphery of the shaft 14. The linkage 15 is provided with a through hole for the shaft 14 to pass through. The through hole is provided with two right-angled bosses 151 that are rotationally symmetrical about its center. Two fan-shaped clutch grooves 152 are formed between the two right-angled bosses 151. The drive assembly 16 can drive the linkage 15 to rotate. The linkage 15 drives the shaft 14 to rotate through the right-angled bosses 151, or rotates independently relative to the shaft 14 through the clutch groove 152.

[0041] It can be seen from the above technical solution that the linkage member 15 is provided with a right-angled boss 151, and the driving assembly 16 can drive the linkage member 15 to rotate clockwise or counterclockwise. The linkage member 15 then drives the shaft 14 to rotate through the right-angled boss 151, thereby extending or retracting the lock tongue 31. At the same time, the lock core 13 is provided with a keyhole for inserting a key. The key can drive the lock core 13 to rotate, thereby driving the shaft 14 to rotate. The linkage 15 is also provided with two fan-shaped clutch grooves 152. When the linkage 15 drives the shaft 14 to rotate, the drive assembly 16 drives the linkage 15 to rotate in the opposite direction. At this time, the linkage 15 avoids the shaft 14 through the clutch groove 152 and rotates independently. At the same time, after the reverse rotation, the clutch groove 152 is located in front of the next rotation of the shaft 14, thereby providing space for using the key to drive the shaft 14. When the user uses the key to switch the lock, the shaft 14 can rotate independently relative to the linkage 15, thereby avoiding driving the drive assembly 16. On the one hand, it can avoid the drive assembly 16 from blocking the shaft 14, thereby improving the safety of product use; on the other hand, it can avoid driving the drive assembly 16 through the shaft 14, thereby extending the service life of the product.

[0042] Please refer to Figure 5 and Figure 6 , fasteners 121 are symmetrically provided on both sides of the battery box 12, and the fasteners 121 include a bent section 1211, a connecting section 1212, and a fastener section 1213 connected in sequence. One end of the bent section 1211 is connected to the battery box 12, and the other end is bent parallel to the side of the battery box 12. The connecting section 1212 extends toward the battery box 12 perpendicular to the bent section 1211. The fastener section 1213 is connected to the bent section 1211 and extends in a direction parallel to the side of the battery box 12.

[0043] Exemplarily, the housing 11 has a cavity inside, and the lower end of the housing 11 has an opening connected to the cavity, so that the battery box 12 can extend into the housing 11 from the lower end. A latch 121 is provided at the lower end of the battery box 12, and two latches 121 are provided on the surfaces of both sides of the battery box 12. A bent section 1211 extends horizontally outward from the side of the battery box 12 for a certain distance, then bends and extends in a direction parallel to the side of the battery box 12. The bent section 1211 is preferably arc-shaped to match the contour of the housing 11. One end of the connecting section 1212 is connected to the bent section 1211, and the other end extends horizontally toward the battery box 12. The latch section 1213 is perpendicular to the connecting section 1212. One end of the latch section 1213 is connected to the connecting section 1212, and the other end is provided with a latch on the side surface facing away from the battery box 12. It is understood that the distance between the two latches 121 matches the width of the opening. Under pressure, the two latches 121 can move closer to the battery compartment 12, so that the distance between them is less than the width of the opening. The latches 121 and the battery compartment 12 are integrally formed. The latches 121 and the battery compartment 12 can be made of existing plastic or metal materials. The only requirement is that the bent section 1211 has the elasticity to restore the latch section 1213. This embodiment is not limited here.

[0044] The battery box 12 is provided with a latch 121, which includes a bent section 1211, a connecting section 1212, and a latch section 1213 connected in sequence. The latch section 1213 is connected to the bent section 1211 and extends in a direction parallel to the side of the battery box 12, so that the latch section 1213 can be moved closer to the battery box 12 under the action of an external force. When installing, the battery box 12 is pushed into the cavity, and the two latches 121 are pressed by fingers to move the latch section 1213 closer to the battery box 12. The battery box 12 is close, and when the battery box 12 slides into place, the pressure is released, and the snap section 1213 is reset under the elastic force of the bent section 1211, thereby snapping into contact with the shell 11. When disassembling, you only need to press the two snap parts 121 with your fingers to separate the snap section 1213 from the shell 11, and then pull out the battery box 12. The operation is simple and convenient, effectively improving the efficiency of battery replacement and enhancing the user experience. The overall structure is simple and reasonable, which is conducive to the miniaturization of the deadbolt body 3.

[0045] Please refer to Figure 7The right-angled boss 151 includes a first surface 1511 and a second surface 1512 that are perpendicular to each other. The first surfaces 1511 and the second surfaces 1512 of the two right-angled bosses 151 are parallel to each other. The linkage member 15 drives the shaft 14 to rotate forward or reverse via the first surface 1511 or the second surface 1512. The shaft 14 has two states: unlocked and locked. In these states, the first surface 1511 or the second surface 1512 is respectively abutted against the shaft 14. In this state, rotating the linkage member 15 drives the shaft 14 via the first surface 1511 or the second surface 1512, thereby switching the shaft 14 from one state to the other.

[0046] This embodiment also includes a sensing member 17, which is arranged on the outer periphery of the linkage member 15. A first boss 153 is provided on the outer periphery of the linkage member 15, and second bosses 154 are provided on both sides of the first boss 153. The linkage member 15 can rotate so that the first boss 153 or the second boss 154 contacts the sensing member 17. The sensing member 17 can determine the rotation position of the linkage member 15 by sensing the first boss 153 and the second boss 154. Specifically, in the initial state, the first boss 153 is against the sensing member 17. When the user performs an unlocking or locking action, the linkage member 15 rotates clockwise or counterclockwise, so that one of the second bosses 154 contacts the sensing member 17. At this time, the sensing member 17 obtains the first contact signal, and then the linkage member 15 rotates in the opposite direction to reset, so that the first boss 153 contacts the sensing member 17 again. At this time, the sensing member 17 obtains the second contact signal, that is, in each complete unlocking or locking action of the linkage member 15, the sensing member 17 will obtain two contact signals. The number of contact signals can be used to determine whether the linkage member 15 has rotated into place or whether the unlocking or locking action is completed.

[0047] The angle between the line connecting the first boss 153 and the center of the linkage member 15 and the line connecting the second boss 154 and the center of the linkage member 15 is 90°. By setting the angle between the line connecting the first boss 153 and the second boss 154 and the center of the linkage member 15, the required rotation angle of the linkage member 15 for each unlocking and locking action can be determined, thereby determining whether the linkage member 15 has been fully engaged.

[0048] Please refer to Figure 8 In order to facilitate the understanding of the above technical solution, the following describes its working principle: the shaft 14 has two states: unlocked and locked. Figure 7The shaft 14 in state a is in the locked state, and it needs to be rotated 90° counterclockwise to switch from the locked state to the unlocked state. The lock can be unlocked by a key or by electric unlocking. When the key is used to unlock, since the clutch slot 152 is located on the path of the shaft 14 rotating counterclockwise, the key unlocking can make the shaft 14 rotate along the clutch slot 152 without driving the linkage 15. When electric unlocking is used, the drive assembly 16 drives the linkage 15 to rotate counterclockwise, and the linkage 15 drives the shaft 14 to rotate counterclockwise through the first surface 1511 of the right-angle boss 151. When the sensor 17 senses the contact signal of the second boss 154, it means that the locking action has been completed. At this time, the shaft 14 is in a vertical state, that is, Figure 7 Then the driving member 161 rotates in the opposite direction, driving the linkage member 15 to rotate clockwise. Due to the clutch slot 152, the linkage member 15 rotates independently relative to the shaft 14. When the sensing member 17 senses the contact signal of the first boss 153, it indicates that the linkage member 15 is reset to its original position, the driving member 161 stops, and the locking action is completed. Figure 7 If you want to use the key to unlock the door, you need to use the key to drive the shaft 14 to rotate 90 degrees clockwise. Since the clutch slot 152 is located in front of the path of the clockwise rotation of the shaft 14, the key can be used to drive the shaft 14 to rotate independently without driving the linkage member 15.

[0049] In this embodiment, the distance between the planes where the two first surfaces 1511 are located, and the distance between the planes where the two second surfaces 1512 are located are equal to the thickness of the shaft 14 and smaller than the width of the shaft 14, thereby ensuring that the two first surfaces 1511 or the two second surfaces 1512 can be tightly against the surface of the shaft 14, thereby improving the efficiency and stability of driving the shaft 14 to rotate.

[0050] The drive assembly 16 includes a drive member 161 and a first gear 162 connected to the drive member 161. A second gear 155 is provided on the outer periphery of the linkage member 15, and the second gear 155 meshes with the first gear 162. The drive member 161 drives the linkage member 15 to rotate through the cooperation of the first gear 162 and the second gear 155, resulting in a simple and reasonable structure.

[0051] Please refer to Figure 5 and Figure 6 The battery box 12 includes a plurality of slots 122, each of which is provided with an elastic conductive member 123 and a conductive sheet 124 at both ends. The conductive sheet 124 and the elastic conductive member 123 are both made of conductive metal and are used to connect the positive and negative poles of the battery. The battery installed in the battery box 12 can be connected through the elastic conductive member 123 and the conductive sheet 124, thereby powering the electronic components in the lock body 3.

[0052] A conductive contact 125 is provided at one end of the battery compartment 12. This contact 125 is electrically connected to the elastic conductive member 123 and the conductive sheet 124. A conductive spring is provided within the housing 11 for contacting the conductive contact 125. When the battery compartment 12 is inserted into the cavity, the conductive contact 125 contacts the conductive spring, thereby connecting the battery to the circuit within the lock body 3 and enabling quick installation and removal of the battery compartment 12.

[0053] In this embodiment, there are at least two groups of conductive contacts 125. Arranging the conductive contacts 125 in at least two groups allows the lock body 3 to be powered through the other group of conductive contacts 125 when one group of conductive contacts 125 fails or has a poor connection, thereby improving connection reliability.
