Description

Technical Field

[0001] The present invention relates to the technical field of locks, in particular to an electric ball cylinder lock. Background Art

[0002] Ball locks are popular among users because they are easy to hold and can be turned to unlock. There are two commonly used ball locks: one is the most widely used three-bar lock, and the other is the traditional ball cylinder lock.

[0003] Among them, the three-bar lock includes a front lock body, a rear lock body, a square rod connected between the front lock body and the rear lock body, and a straight-cylinder lock tongue for the square rod to pass through. Two screws for fixing the front lock body and the rear lock body are also provided between the front lock body and the rear lock body. Since the square rod needs to be rotated to link the lock tongue piece of the straight-cylinder lock tongue to extend, the internal structure of the straight-cylinder lock tongue is generally a multi-link mechanism, and most of the components of the three-bar lock are solid parts, so the overall cost of the three-bar lock is relatively high.

[0004] The ball cylinder lock uses a large number of thin-walled cylindrical parts and shell parts to directly drive the lock tongue part to move along the radial extension and contraction of the ball cylinder lock. Therefore, the ball cylinder lock has the characteristic of low material cost. However, due to the large number of parts and assembly production processes of traditional ball cylinder locks, the production efficiency is low. Therefore, the ball cylinder lock is gradually replaced by the three-bar lock.

[0005] Since the structure of a three-bar lock is relatively simple, in order to meet the need for electric unlocking, three-bar locks with electric unlocking have also appeared in the relevant technology. However, due to the complex structure and limited internal space of traditional ball cylinder locks, it is extremely difficult to convert traditional ball cylinder locks into electric unlocking methods. The present invention is proposed to solve the problem of electric unlocking of lock cylinder locks in the existing technology. Summary of the Invention

[0030] Reference Figures 1 to 5An electric ball cylinder lock according to an embodiment of the present invention comprises: a front ball lock 100, the front ball lock 100 comprising a front fixing sleeve 110, a first switch cylinder 120 rotatably arranged in the front fixing sleeve 110, a second switch cylinder 130 rotatably arranged in the first switch cylinder 120, one end of the first switch cylinder 120 is rotatably connected to a front handle sleeve 140, an electric clutch mechanism 300 is provided between the front handle sleeve 140 and the first switch sleeve 120, and the front handle sleeve 140 is connected to the second switch sleeve 130; a rear ball lock 200, the rear ball lock 200 comprising a front fixing sleeve 110 and a second switch sleeve 130; The rear fixing sleeve 210 is connected to the front fixing sleeve 110, and an accommodating cavity 30 is defined between the rear fixing sleeve 210 and the front fixing sleeve 110. A slider member 400 is provided in the accommodating cavity 30, which can be telescopically moved along the side of the front fixing sleeve 110 or the rear fixing sleeve 210. The slider member 400 is used to connect to the lock tongue member 500. When the first switch cylinder 120 and the second switch cylinder 130 rotate, they can contact the slider member 400 to drive the slider member 400 to retract into the accommodating cavity 30. The rear fixing sleeve 210 is movably provided with a rear lock assembly 600 that can prevent the first switch cylinder 120 from rotating relative to the front fixing sleeve 110.

[0031] The electric ball cylinder lock of the above structure uses the rear lock assembly 600 to lock the position of the first switch cylinder 120 when it is locked to prevent the first switch cylinder 120 from rotating relative to the front fixing sleeve 110. Before the electric clutch mechanism 300 works, the first switch cylinder 120 and the front handlebar sleeve 140 are connected together. Since the first switch cylinder 120 is locked, the front handlebar sleeve 140 cannot rotate either. The user cannot rotate the front handlebar sleeve 140 to unlock the door. When the electric clutch mechanism 300 is controlled to operate, the front handlebar sleeve 140 and the first switch cylinder 120 are connected together. The switch cylinder 120 is separated, and the front handle sleeve 140 can drive the second switch cylinder 130 to rotate relative to the front fixed sleeve 110, so that the rotation of the second switch cylinder 130 drives the slider 400 and the lock tongue member 500 on the slider 400 to retract into the accommodating cavity 30, thereby realizing the unlocking function; the electric ball cylinder lock realizes the electric unlocking function with a simple and ingenious structure without increasing the overall size of the traditional ball cylinder lock and without significantly changing the overall structure of the ball cylinder lock, and has low material cost and convenient assembly.

[0032] See also Figure 2 、 Figure 3 and Figure 4In some embodiments of the present invention, the rear lock assembly 600 includes a locking rod 610 that is telescopically mounted on the rear fixing sleeve 210 along the axial direction of the second switch cylinder 130. The locking rod 610 is provided with a clamping portion 611. The first switch cylinder 120 and the front fixing sleeve 110 are respectively provided with a first clamping groove 124 and a second clamping groove 113 that cooperate with the clamping portion 611. The locking rod 610 has a locked position and an unlocked position. The slider 400 is provided with a locking piece 420. The slider 400 is connected to a first elastic member 410 that drives the slider 400 to extend and move. When the slider 400 is extended, the locking piece 420 abuts against the locking rod 610 to stabilize the locking rod 610 in the locked position. It can be understood that when the electric ball cylinder lock needs to be locked, the user pushes the locking rod 610 to retract relative to the rear fixing sleeve 210 to move to the locked position, and the slider member 400 extends along the side of the front fixing sleeve 110 or the rear fixing sleeve 210 under the action of the first elastic member 410. At the same time, the locking piece 420 is also kept against the locking rod 610 under the action of the first elastic member 410, thereby preventing the locking rod 610 from extending relative to the rear fixing sleeve 210 and moving to the unlocked position, that is, keeping the locking rod 610 in the locked position. At this time, the clamping portion 611 on the locking rod 610 is simultaneously engaged in the first clamping groove portion 124 and the second clamping groove portion 113, and the first switch cylinder 120 and the front handle sleeve 140 connected to the first switch cylinder 120 cannot rotate. When the electric ball lock needs to be unlocked, the electric clutch mechanism 300 drives the front handle sleeve 140 and the first switch sleeve 120 to separate. The front handle sleeve 140 drives the second switch sleeve 130 to rotate relative to the front fixed sleeve 110. The rotation of the second switch sleeve 130 drives the slider 400 and the lock tongue member 500 on the slider 400 to retract into the accommodating chamber 30, thereby achieving the unlocking function. As the slider 400 retracts into the accommodating chamber 30, the first elastic member 410 is compressed, and the locking piece 420 moves with the slider 400 away from the locking rod 610, allowing the locking rod 610 to extend to the unlocked position relative to the rear fixed sleeve 210. The above rear lock assembly 600 has a simple structure, is easy to operate, and is low in cost.

[0033] See also Figure 2 and Figure 4In some embodiments of the present invention, the rear ball lock 200 includes a rear handlebar sleeve 220 connected to the rear fixing sleeve 210. A rear switch cylinder 230 is rotatably provided in the rear fixing sleeve 210 and is capable of contacting the slider member 400 to drive the slider member 400 to retract into the accommodating chamber 30. The locking rod 610 is provided through the rear switch cylinder 230 and the second switch cylinder 130. An operating member 620 protruding from the rear handlebar sleeve 220 is provided at one end of the locking rod 610 away from the second switch cylinder 130. A blocking portion 612 corresponding to the locking piece 420 is provided on the side of the locking rod 610, wherein the blocking portion 612 has a guiding slope inclined upward in the direction from the front ball lock 100 to the rear ball lock 200. A second elastic member 131 is provided between the second switch cylinder 130 and the locking rod 610. The second elastic member 131 is used to drive the operating member 620 to extend out of the rear handlebar sleeve 220 to switch the locking rod 610 from the locked position to the unlocked position. For further information, see Figure 5 The operating member 620 is rotatably disposed at the end of the locking rod 610 away from the second switch cylinder 130. A notch 231 is provided at the end of the rear switch cylinder 230. The notch 231 has a curved groove portion 232 arranged around the circumference of the rear switch cylinder 230. The operating member 620 is provided with an anti-slip protrusion 621 that can enter the curved groove portion 232 along the notch 231. The anti-slip protrusion 621 is located within the curved groove portion 232 to prevent the locking rod 610 from being stabilized in the locked position.

[0034] It should be noted that there are two ways for the rear lock assembly 600 to stabilize the locking rod 610 in the locked position, see Figures 2 to 4 One way is to directly push the locking rod 610 forward by the operating member 620, and the locking piece 420 moves upward along the guide slope and then crosses the guide slope. Under the joint action of the first elastic member 410 and the second elastic member 131, the locking piece 420 abuts against the locking rod 610 to keep the locking rod 610 in the locked position. When the electric clutch mechanism 300 drives the front handle sleeve 140 and the first switch cylinder 120 to separate, the front handle sleeve 140 drives the second switch cylinder 130 to rotate relative to each other to retract the lock tongue member 500. At the same time, after the locking piece 420 moves away from the locking rod 610, the locking rod 610 extends to the unlocked position relative to the rear fixing sleeve 210 under the action of the second elastic member 131. Thereafter, the user can unlock the door by rotating the front handle sleeve 140 again, or the user can unlock the door by rotating the rear handle sleeve 220 to drive the rear switch cylinder 230. That is, after one unlocking, the electric ball cylinder lock is in a free-open state. Figure 2 、 Figure 4 and Figure 5When the locking lever 610 is moved to the locked position, the user rotates the operating member 620 again, and the anti-slip protrusion 621 enters the curved groove 232. At this time, even if the slider 400 and the lock tongue member 500 are retracted to drive the locking piece 420 away from the locking lever 610, the locking lever 610 cannot extend to the unlocked position relative to the rear fixing sleeve 210 under the action of the second elastic member 131. That is, after one unlocking, the electric ball cylinder lock still needs to drive the second switch cylinder 130 to rotate to drive the slider 400 and the lock tongue member 500 to retract. There is no need to operate the rear lock assembly 600 again to achieve locking each time the door is closed, thereby improving safety and convenience.

[0035] See also Figure 1 and Figure 2 In some embodiments of the present invention, to achieve keyless unlocking, an identification control module 700 is provided on the front handlebar sleeve 140 and is electrically connected to the electric clutch mechanism 300. After the identification control module 700 inputs preset identity information, the electric clutch mechanism 300 drives the front handlebar sleeve 140 to separate from the first switch cylinder 120, allowing the front handlebar sleeve 140 to rotate the second switch cylinder 130 and retract the lock tongue member 500 on the slider 400. It is understood that the identification control module 700 can be implemented as one or more of a fingerprint module, a password input pad, or a card access control module. In this embodiment, the identification control module 700 is a fingerprint module. Once the user inputs a preset, correct fingerprint, the electric clutch mechanism 300 is activated, driving the handlebar sleeve and the first switch cylinder 120 apart. Of course, in other embodiments, the identification control module 700 can also be remotely controlled by a mobile terminal through an app, thereby meeting the needs of smart homes.

[0036] See also Figure 3In some embodiments of the present invention, the electric clutch mechanism 300 includes a clutch pin 310 telescopically mounted on the front handlebar sleeve 140. The first switch cylinder 120 is provided with a latch hole 320 that mates with the clutch pin 310. The clutch pin 310 is coupled to a magnetic assembly that drives it into or out of the latch hole 320. A mechanical lock core 800 is disposed within the front handlebar sleeve 140. The output end of the mechanical lock core 800 is provided with a driving member 810 that can drive the clutch pin 310 away from the latch hole 320. It will be appreciated that the provision of the mechanical lock core 800 within the front handlebar sleeve 140 facilitates further expanding the unlocking methods of the electric ball lock, prevents the electric clutch mechanism 300 from failing and becoming unlockable, and improves the reliability of the electric ball lock. When the electric clutch mechanism 300 is not in operation, the magnetic force of the magnetic assembly drives the clutch pin 310 into the latch hole 320, connecting the front handlebar sleeve 140 and the first switch cylinder 120. When the electric clutch mechanism 300 is in operation, the magnetic force of the magnetic assembly drives the clutch pin 310 out of the latch hole 320, separating the front handlebar sleeve 140 and the first switch cylinder 120. When a key is inserted into the mechanical lock cylinder 800, turning the key drives the driver 810 to act on the clutch pin 310, separating the clutch pin 310 from the latch hole 320. The front handlebar sleeve 140 then drives the second switch cylinder 130 to rotate together. Compared with the traditional method of using an electric push rod, the use of a magnetic component is simpler, has lower assembly difficulty, and has a faster response rate. Moreover, it is precisely because the magnetic component is used to drive the clutch pin 310 to move telescopically, and the clutch pin 310 has no rigid connection with other components, so that the driving member 810 at the output end of the mechanical lock core 800 can also drive the clutch pin 310 to move, and there is no need to set up multiple clutch pins 310 and pin holes 320, which simplifies the structure of the two combined methods of mechanical unlocking and electric unlocking.

[0037] See also Figure 3In some embodiments of the present invention, the driving member 810 is a shift block that is rotatably arranged at the output end of the mechanical lock cylinder 800. A side extension portion 311 is provided on the side of the clutch pin 310, and the shift block is provided with a driving inclined surface 820 that abuts against the side extension portion 311. The driving inclined surface 820 is inclined along the extension direction of the clutch pin 310. When the shift block rotates, the side extension portion 311 moves along the driving inclined surface 820 to enable the clutch pin 310 to overcome the action of the magnetic component and move away from the pin hole 320. When the user inserts the key into the keyhole of the mechanical lock cylinder 800 and turns it, the driving inclined surface 820 abuts against the side extension 311 of the clutch pin 310. During the rotation of the dial block, the side extension 311 moves on the driving inclined surface 820 to drive the clutch pin 310 to gradually be withdrawn from the pin hole 320. The structure of the mechanical lock cylinder 800 and the electric clutch mechanism 300 only needs to use one clutch pin 310, which is very simple and small in size, and meets the requirements of placing the electric clutch mechanism 300, the mechanical lock cylinder 800, and the drive circuit board and battery connected to the electric clutch mechanism 300 in the front handlebar sleeve 140.

[0038] See also Figure 3 In some embodiments of the present invention, a motor 150 is fixedly installed in the front handle glove sleeve 140, and a rotating block 160 is provided on the output shaft of the motor 150. The rotating block 160 and the clutch pin 310 are both circumferentially distributed with a first magnet 10 and a second magnet 20 around the output shaft of the motor 150. The magnetic poles of the ends of the first magnet 10 and the second magnet 20 that are close to each other are opposite, and the two first magnets 10 and the two second magnets 20 together constitute a magnetic assembly. Specifically, on the end face of the rotating block 160 facing the clutch pin 310, the magnetic poles of the first magnet 10 and the second magnet 20 on the rotating block 160 are respectively the north pole and the south pole. On the end face of the clutch pin 310 facing the rotating block 160, the magnetic poles of the first magnet 10 and the second magnet 20 on the clutch pin 310 are respectively the north pole and the south pole. When the two first magnets 10 are aligned, the two second magnets 20 are also aligned, thereby generating a mutual repulsion effect, so that the clutch pin 310 is inserted into the latch hole 320; when the two first magnets 10 are respectively aligned with the two second magnets 20, a mutual attraction effect is generated, so that the clutch pin 310 is withdrawn from the latch hole 320. The above magnetic assembly has a simple and ingenious structure. The motor 150 can drive the clutch pin 310 to extend or retract by rotating 180 degrees, and the action response is fast and the noise is low.

[0039] See also Figure 2 and Figure 3In some embodiments of the present invention, the first switch cylinder 120 includes a cylindrical member 121 and an annular member 122 fixedly mounted on the exterior of the cylindrical member 121. The annular member 122 is provided with an annular shoulder 123. The front handlebar sleeve 140 is provided with an annular guide groove 141 that mates with the annular shoulder 123. The front handlebar sleeve 140 is provided with a scale lock portion 142 that passes through the middle of the annular member 122 and is connected to the second switch cylinder 130. It should be noted that in this embodiment, an axial hole is provided in the middle of the annular member 122. The front handlebar sleeve 140 has a neck portion that passes through the axial hole. The scale lock portion 142 is provided on the neck portion. The axial hole, annular shoulder 123, and annular guide groove 141 are all coaxially arranged with the rotation axis of the front handlebar sleeve 140. The annular shoulder 123 and annular guide groove 141 cooperate, and the neck portion and the axial hole cooperate to collectively guide the rotation of the front handlebar sleeve 140 relative to the annular member 122. When the handle sleeve drives the locking member 142 to rotate, the second switch cylinder 130 can rotate, driving the locking tongue member 500 on the slider 400 to move into the accommodating cavity 30. This layout allows the front handle sleeve 140 to rotate relative to the first switch cylinder 120 and also connects the front handle sleeve 140 to the second switch cylinder 130. Most of the components are hollow cylindrical, which reduces material costs and is lightweight.

[0040] See also Figure 4 The end of the first switch cylinder 120 near the slider 400, the end of the second switch cylinder 130 near the slider 400, and the end of the rear switch cylinder 230 near the slider 400 are all provided with curved plates that abut against the slider 400. When the first switch cylinder 120, the second switch cylinder 130, and the rear switch cylinder 230 rotate, the corresponding curved plates push the slider 400 in the direction of compressing the first elastic member 410. It should be noted that the rotation of the second switch cylinder 130 does not cause the locking lever 610 to rotate.

[0041] See also Figure 4In some embodiments of the present invention, the front fixing sleeve 110 includes a front sleeve 111 and a first half shell 112 formed at one end of the front sleeve 111, and the rear fixing sleeve 210 includes a rear sleeve 211 and a second half shell 212 formed at one end of the rear sleeve 211. The first half shell 112 and the second half shell 212 are spliced ​​to form a shell assembly having an accommodating cavity 30.
