Description
TECHNICAL FIELD
[0001] The utility model belongs to the technical field of lockset, concretely relates to an electronic lock. BACKGROUND
[0002] Under the dual needs of intelligent security and convenient access, electronic locks are gradually popularized in various access scenes. The electronic locks on the market at present generally adopt a mechanical transmission mode of motor driving gear rotation, the rotation of the gear transmits power to the lock core paddle, drives the lock core paddle to rotate, the movement of the lock core paddle is then conducted to the lock tongue, drives the lock tongue to complete the action of extending or retreating, so as to realize the locking and unlocking functions of the electronic lock.
[0003] In order to accurately control the locking and unlocking state of the electronic lock, multiple sensors are usually arranged in the prior art to monitor the rotation of the gear. Specifically, a widely used scheme in the industry is to configure multiple photoelectric switches and multiple Hall sensors. The photoelectric switch detects the rotation position of the gear based on the shielding or reflection of light, and the Hall sensor captures the rotation information of the gear according to the change of the magnetic field, and the two work together to realize accurate monitoring of the rotation of the gear, and indirectly reflect the locking or unlocking state of the electronic lock.
[0004] However, this scheme of monitoring the rotation of the gear by relying on multiple sensors has some drawbacks that cannot be ignored. On the one hand, the procurement cost of multiple types and quantities of sensors is high, and the assembly complexity and fault risk points of the electronic lock are increased, greatly increasing the production cost of the electronic lock; on the other hand, in order to reasonably arrange these sensors in a limited space, it inevitably leads to an increase in the overall volume of the electronic lock, not only affecting the flexibility of product appearance design, but also bringing inconvenience to the user's installation and carrying, limiting the application of the electronic lock in some scenes with strict space requirements.
[0005] In addition, the arrangement of multiple sensors requires more labor and time cost for accurate installation and debugging during the production and assembly process of the electronic lock, further increasing the labor cost. Moreover, the concentrated arrangement of numerous electronic components is prone to electromagnetic compatibility problems, reducing the stability and reliability of the electronic lock as a whole, affecting its service life. In actual use, the complex sensor layout also brings great difficulty to the user's after-sales maintenance and replacement of parts, increasing the maintenance cost. UTILITY MODEL CONTENTS

[0041] The electronic lock provided by the present application can realize precise monitoring of the rotation of the tooth disc through a single photoelectric sensor, thereby reducing the number of sensors in the electronic lock, reducing production cost, and reducing the volume of the electronic lock.
[0042] In the typical embodiment of the present application, the electronic lock 100 is installed on the door body, the door body is installed on the door frame, and the door frame is provided with a lock tongue groove. When the lock tongue 160 of the electronic lock 100 extends into the lock tongue groove, the locking of the electronic lock 100 is realized; when the lock tongue 160 of the electronic lock 100 is withdrawn from the lock tongue groove, the unlocking of the electronic lock 100 is realized.
[0043] Specifically, in combination with Figure 1 With Figure 2The electronic lock 100 comprises a rear lock portion 110, a lock cylinder tab 150 and a lock tongue 160, one end of the lock cylinder tab 150 is connected with a lock cylinder of the electronic lock 100, and the lock cylinder tab 150 is further connected with the lock tongue 160, the rear lock portion 110 is used for driving the lock cylinder tab 150 to move, the lock cylinder tab 150 drives the lock tongue 160 to move linearly along the extension direction of the lock tongue 160, so that the lock tongue 160 is inserted into or withdrawn from the lock tongue slot, thereby realizing the locking or unlocking of the electronic lock 100.
[0044] The lock cylinder tab 150 is vertically arranged with the lock tongue 160, and the lock cylinder tab 150 is fixed with the lock tongue 160. Figure 3 The lock cylinder tab 150 is a flat columnar structure, wherein the lock cylinder tab 150 comprises adjacent unlocking faces 151 and locking faces 152, the unlocking faces 151 are perpendicular to the locking faces 152, and the width of the unlocking faces 151 is greater than the width of the locking faces 152. When the lock cylinder tab 150 is rotated so that the unlocking faces 151 of the lock cylinder tab 150 are directed towards the lock tongue slot, the lock tongue 160 is withdrawn from the lock tongue slot, thereby realizing unlocking; when the lock cylinder tab 150 is rotated so that the locking faces 152 of the lock cylinder tab 150 are directed towards the lock tongue slot, the lock tongue 160 is inserted into the lock tongue slot, thereby realizing locking.
[0045] In the typical embodiment of the utility model, the rear lock portion 110 is connected with the lock cylinder tab 150. Figure 4 The rear lock portion 110 is provided with a rotating shaft 111, a toothed disc 120, a linkage block 113, a photoelectric sensor 114, a motor 115 and a control unit, the control unit is electrically connected with the photoelectric sensor 114 and the motor 115 respectively, and the motor 115 is used for driving the toothed disc 120 to rotate. Figure 2 The rotating shaft 111 is connected with the lock cylinder tab 150. Figure 7 The linkage block 113 is arranged on the rotating shaft 111, the toothed disc 120 is provided with a gear hole, the toothed disc 120 is sleeved on the rotating shaft 111 through the gear hole, the gear hole is a circular hole, and the section corresponding to the gear hole of the rotating shaft 111 is a cylindrical structure, so that the gear hole is sleeved on the rotating shaft 111, and the toothed disc 120 cannot directly drive the rotating shaft 111 to rotate.
[0046] In the typical embodiment of the utility model, the rear lock portion 110 is connected with the lock cylinder tab 150. Figure 5 And Figure 7The gear disc 120 is provided with a transmission block 122, and the transmission block 122 and the linkage block 113 on the rotating shaft 111 are arranged on the same rotating path. When the motor 115 drives the gear disc 120 to rotate, the transmission block 122 arranged on the gear disc 120 will move synchronously, because the transmission block 122 and the linkage block 113 are arranged on the same rotating path, the transmission block 122 will abut against the linkage block 113 in the rotating process, so that the transmission block 122 will drive the rotating shaft 111 to rotate through the linkage block 113, the rotating shaft 111 will drive the lock core paddle 150 to rotate, and the lock core paddle 150 will drive the lock tongue 160 to move linearly, so that the lock tongue 160 extends into or exits the lock tongue slot, so that the electronic lock 100 is locked or unlocked.
[0047] In combination Figure 5 With Figure 6 The gear disc 120 is provided with a plurality of light blocking pieces 130, and the gear disc 120 will drive the light blocking pieces 130 to rotate synchronously. The photoelectric sensor 114 is arranged on the rotating path of the light blocking pieces 130. When the gear disc 120 drives the light blocking pieces 130 to pass through the photoelectric sensor 114, the light blocking pieces 130 will block the light emitted by the photoelectric sensor 114, so that the photoelectric sensor 114 generates a light blocking signal. The photoelectric sensor 114 outputs the light blocking signal to the control unit, and the control unit obtains the rotating angle of the gear disc 120 based on the light blocking signal, and judges the working state of the electronic lock 100.
[0048] In this embodiment, the gear disc 120 is provided with a plurality of light blocking pieces 130, and the plurality of light blocking pieces 130 are arranged in the circumferential direction of the gear disc 120. For example, the gear disc 120 is provided with two light blocking pieces 130, and the two light blocking pieces 130 are arranged at 180°. The gear disc 120 is provided with three light blocking pieces 130, and the three light blocking pieces 130 are arranged in sequence along the circumferential direction of the gear disc 120, and adjacent two light blocking pieces 130 are arranged at 120°.
[0049] In this embodiment, the present invention is described using the example of four light-blocking plates 130 on the gear disk 120, but this should not be construed as a limitation of the present invention. Specifically, the four light-blocking plates 130 are arranged sequentially along the circumference of the gear disk 120, with adjacent light-blocking plates 130 at 90° intervals. When the motor 115 drives the gear disk 120 to rotate, the gear disk 120 will drive the four light-blocking plates 130 to rotate synchronously. Assuming that when the gear disk 120 is not rotating, the angle at which the photoelectric sensor 114 is blocked by one of the light-blocking plates 130 is 0°; when the motor 115 drives the gear disk 120 to rotate, and the photoelectric sensor 114 is blocked by another light-blocking plate 130, the control unit receives the light-blocking signal output by the photoelectric sensor 114, and the control unit determines that the gear disk 120 has rotated 90°.
[0050] The control unit controls the rotation direction of the gear 120 by controlling the forward and reverse rotation of the motor 115. By controlling the rotation of the gear 120, the control unit controls the rotation of the lock cylinder lever 150, thereby controlling the bolt 160 to extend into or retract from the bolt groove, and ultimately controlling the locking or unlocking of the electronic lock 100. Furthermore, the control unit monitors the rotation angle of the gear 120 using a photoelectric sensor 114 to prevent the rotation angle from being too large or too small, ensuring that the electronic lock 100 accurately locks or unlocks.
[0051] In this embodiment, combined with Figure 5 The transmission block 122 extends along the circumference of the gear disk 120, such that its two end faces 1221 along the circumference are angled. One of these end faces 1221 can abut against the linkage block 113 on the rotating shaft 111, thereby driving the rotating shaft 111 to rotate via the linkage block 113. Specifically, when the control unit controls the motor 115 to rotate forward, one end face 1221 abuts against the linkage block 113; when the control unit controls the motor 115 to rotate in reverse, the other end face 1221 abuts against the linkage block 113. This improves the rotation efficiency of the gear disk 120. In this invention, it is recommended that the transmission block 122 be arranged across 180°, that is, the two end faces 1221 are arranged at 180°, so that when the motor 115 rotates forward or in reverse, the rotation angle of the transmission block 122 can be reduced, allowing it to quickly abut against the linkage block 113.
[0052] In the typical embodiment of the utility model, the tooth disc 120 is equipped with a stroke groove 121, the stroke groove 121 is arranged along the circumferential direction of the tooth disc 120, and the stroke groove 121 and the transmission block 122 are arranged along the same extension path, the stroke groove 121 and the transmission block 122 are connected head to tail to form an annular structure. Moreover, the two end faces 1221 of the transmission block 122 form two groove walls of the stroke groove 121 in the circumferential direction. In this embodiment, the transmission block 122 is arranged along the circumferential direction across 180 DEG, and the stroke groove 121 is also arranged along the circumferential direction across 180 DEG as an example, the utility model is described, but it is not understood as the limitation of the utility model.
[0053] In combination Figure 4 With Figure 7 , the rear lock part 110 is also equipped with a linkage ring 118, the linkage ring 118 is sleeved on the rotating shaft 111, and the linkage ring 118 is fixedly arranged with the rotating shaft 111, and the linkage block 113 is fixedly arranged on the linkage ring 118, in other words, the linkage block 113 is fixed on the rotating shaft 111 through the linkage ring 118. In this embodiment, the linkage ring 118 and the linkage block 113 are integrally formed, but it is not understood as the limitation of the utility model.
[0054] In combination Figure 5 With Figure 7 , the tooth disc 120 is equipped with a ring groove 123, and the ring groove 123 is arranged on the inner side of the stroke groove 121, that is to say, the ring groove 123 is closer to the gear hole of the tooth disc 120 than the stroke groove 121. The ring groove 123 is communicated with the stroke groove 121, the linkage ring 118 is arranged in the ring groove 123, and the linkage block 113 on the linkage ring 118 is inserted into the stroke groove 121, so that the linkage block 113 is limited by the stroke groove 121, and the two end faces 1221 of the transmission block 122 can selectively abut against the linkage block 113.
[0055] When the tooth disc 120 rotates, one of the end faces 1221 of the transmission block 122 abuts against the linkage block 113, the tooth disc 120 further rotates to drive the linkage block 113 to rotate through the corresponding end face 1221, the rotating shaft 111 and the lock core tumbler 150 are sequentially driven to rotate through the linkage block 113, and the lock tongue 160 is driven to move linearly, so that the lock tongue 160 is inserted into or withdrawn from the lock tongue groove, and the locking or unlocking of the electronic lock 100 is realized.
[0056] In order to describe the working principle of the electronic lock 100 of the utility model, in combination Figure 9 With Figure 10 , Figure 9A plan view of the assembly of the rotating shaft, the linkage ring and the photoelectric sensor, Figure 10 A plan view of the gear disc 120, assuming that the four light-blocking pieces 130 on the gear disc 120 are sequentially a first light-blocking piece 131, a second light-blocking piece 132, a third light-blocking piece 133 and a fourth light-blocking piece 134 along the circumferential direction of the gear disc 120, and that the two end faces 1221 of the transmission block 122 are respectively a first end face 1222 and a second end face 1223.
[0057] In combination Figure 11 , assuming that the electronic lock 100 is in the locked reset state, the first light-blocking piece 131 is at the photoelectric sensor 114, the photoelectric sensor 114 generates a light-blocking signal, and the control unit determines that the electronic lock 100 is in the locked reset state based on the light-blocking signal. Moreover, the first end face 1222 abuts against the linkage block 113 of the linkage ring 118.
[0058] In combination Figure 11 With Figure 12 , when the electronic lock 100 needs to be unlocked, the control unit controls the motor 115 to rotate clockwise, the motor 115 drives the gear disc 120 to rotate counterclockwise by 90°, and the first end face 1222 on the transmission block 122 drives the linkage ring 118 to rotate counterclockwise by 90° through the linkage block 113.
[0059] Among them, the first light-blocking piece 131 on the gear disc 120 will move away from the photoelectric sensor 114, the photoelectric sensor 114 no longer generates a light-blocking signal, but generates a photoelectric signal, and the control unit receives the photoelectric signal, then the control unit determines that the first light-blocking piece 131 has moved away from the photoelectric sensor 114. At the same time, the fourth light-blocking piece 134 on the gear disc 120 will rotate counterclockwise by 90° to the photoelectric sensor 114, the fourth light-blocking piece 134 will shield the light emitted by the photoelectric sensor 114, again generating a light-blocking signal, the control unit receives the light-blocking signal, determines that the fourth light-blocking piece 134 has rotated to the photoelectric sensor 114, and determines that the electronic lock 100 has completed unlocking. At the same time, the first end face 1222 on the gear disc 120 also drives the linkage ring 118, the rotating shaft 111, the lock core paddle 150 and the lock tongue 160 to rotate, so that the lock tongue 160 retreats relative to the lock tongue groove, to complete the unlocking, so that the electronic lock 100 is in the unlocked state.
[0060] In combination Figure 12 With Figure 13When the electronic lock 100 is in the unlocking state, the control unit controls the motor 115 to reverse, the motor 115 drives the gear disc 120 to rotate clockwise by 180°, so that the first end surface 1222 of the transmission block 122 rotates clockwise by 180° to separate from the linkage block 113, and the second end surface 1223 of the transmission block 122 rotates clockwise by 180° synchronously to abut against the linkage block 113. During the clockwise rotation of the gear disc 120 by 180°, the first end surface 1222 and the second end surface 1223 do not link with the linkage block 113, so that the gear disc 120 does not drive the linkage ring 118, the rotating shaft 111, the lock core paddle 150 and the lock tongue 160 to rotate through the linkage block 113. During the clockwise rotation of the gear disc 120 by 180°, the fourth light blocking piece 134 will leave the position of the photoelectric sensor 114, so that the photoelectric sensor 114 generates a photoelectric signal, and the first light blocking piece 131 and the second light blocking piece 132 pass through the position of the photoelectric sensor 114 in turn, the photoelectric sensor 114 generates a light blocking signal, a photoelectric signal and a light blocking signal in turn based on the first light blocking piece 131 and the second light blocking piece 132, and the second light blocking piece 132 stays at the position of the photoelectric sensor 114. The control unit receives the photoelectric signal and the light blocking signal output by the photoelectric sensor 114 in turn, so that the control unit judges that the electronic lock 100 is in the unlocking reset state, and prepares for the subsequent locking of the electronic lock 100.
[0061] In combination Figure 13 With Figure 14 When the electronic lock 100 is in the unlocking reset state and needs to be locked, the control unit controls the motor 115 to reverse, the motor 115 drives the gear disc 120 to rotate clockwise by 90°, so that the second end surface 1223 of the transmission block 122 drives the abutting linkage block 113 to rotate clockwise by 90°, and the linkage block 113 drives the linkage ring 118, the rotating shaft 111, the lock core paddle 150 and the lock tongue 160 to move synchronously, so that the lock tongue 160 extends relative to the lock tongue slot and is inserted into the lock tongue slot, thereby making the electronic lock 100 in the locked state. During the clockwise rotation of the gear disc 120 by 90°, the second light blocking piece 132 will leave the position of the photoelectric sensor 114, so that the photoelectric sensor 114 generates a photoelectric signal; then the third light blocking piece 133 will rotate clockwise by 90° to the position of the photoelectric sensor 114, the photoelectric sensor 114 generates a light blocking signal correspondingly, and the third light blocking piece 133 stays at the position of the photoelectric sensor 114. The control unit receives the photoelectric signal and the light blocking signal output by the photoelectric sensor 114 in turn, so that the control unit judges that the electronic lock 100 is in the locked state.
[0062] Combining Figure 14 With Figure 11 When the electronic lock 100 is in the locked state, the control unit controls the motor 115 to rotate forward, the motor 115 drives the gear disc 120 to rotate counterclockwise by 180°, so that the second end surface 1223 of the transmission block 122 rotates counterclockwise by 180° to separate from the linkage block 113, and the first end surface 1222 of the transmission block 122 synchronously rotates counterclockwise by 180° to abut against the linkage block 113. During the rotation of the gear disc 120, the first end surface 1222 and the second end surface 1223 do not link with the linkage block 113, so that the gear disc 120 does not drive the linkage ring 118, the shaft 111, the lock core tab 150 and the lock tongue 160 to rotate. During the counterclockwise rotation of the gear disc 120 by 180°, the third light blocking piece 133 will leave the position of the photoelectric sensor 114, so that the photoelectric sensor 114 generates a photoelectric signal, and the second light blocking piece 132 and the first light blocking piece 131 pass through the position of the photoelectric sensor 114 in turn, the photoelectric sensor 114 generates a light blocking signal, a photoelectric signal and a light blocking signal in turn based on the second light blocking piece 132 and the first light blocking piece 131, and the first light blocking piece 131 stays at the position of the photoelectric sensor 114. The control unit receives the photoelectric signal and the light blocking signal output by the photoelectric sensor 114 in turn, so that the control unit correspondingly judges that the electronic lock 100 is in the locked reset state, and prepares for the unlocking of the electronic lock 100.
[0063] Therefore, the above describes the whole process of the electronic lock 100 from the locked reset state to the unlocking state, the unlocked reset state, the locked state and the locked reset state again, the electronic lock 100 can judge the state of the electronic lock 100 through the received photoelectric signal and light blocking signal, so that the control unit can accurately control the work of the electronic lock 100 through only a single photoelectric sensor 114, the number of sensors of the electronic lock 100 is reduced, and the production cost of the electronic lock 100 is reduced.
[0064] In one embodiment, in combination with Figure 6 , Figure 7 and Figure 9 , the rear lock part 110 is further provided with a Hall sensor 141 and a magnet 142, the magnet 142 is arranged on the shaft 111, and the shaft 111 will drive the magnet 142 to rotate synchronously when the shaft 111 rotates. The Hall sensor 141 is arranged on the rotation path of the magnet 142, and the Hall sensor 141 will generate a Hall signal when the magnet 142 approaches the Hall sensor 141.
[0065] In the embodiment, the Hall sensor 141 is arranged adjacent to the photoelectric sensor 114, and the Hall sensor 141 is arranged at 90° with the bolt slot. The magnet 142 is arranged at 90° with the linkage block 113, and the magnet 142 is arranged in the same direction as the locking surface 152 of the lock core tab 150 due to the fixed arrangement of the rotating shaft 111 and the lock core tab 150 and the synchronous rotation of the rotating shaft 111 and the lock core tab 150.
[0066] In combination Figure 11 With Figure 12 When the control unit controls the motor 115 to work, the motor 115 drives the gear plate 120 to rotate, the gear plate 120 drives the rotating shaft 111 to rotate, so that the unlocking surface 151 of the rotating shaft 111 faces the bolt slot, the bolt 160 is withdrawn from the bolt slot, and the electronic lock 100 is unlocked. At the same time, the locking surface 152 of the rotating shaft 111 faces the Hall sensor 141, the magnet 142 is close to the Hall sensor 141, the Hall sensor 141 senses the magnet 142, generates a first Hall signal, and the control unit receives the first Hall signal, so as to determine that the electronic lock 100 is in an unlocking state.
[0067] In combination Figure 13 With Figure 14 When the control unit controls the motor 115 to work, the motor 115 drives the gear plate 120, the rotating shaft 111 and the lock core tab 150 to drive the bolt 160, so that the locking surface 152 of the bolt 160 faces the bolt slot, the bolt 160 is inserted into the bolt slot, and the electronic lock 100 is locked. At the same time, the magnet 142 is away from the Hall sensor 141, the Hall sensor 141 cannot sense the magnet 142, the Hall sensor 141 generates a second Hall signal, and the control unit receives the second Hall signal, so as to determine that the electronic lock 100 is in a locking state.
[0068] Therefore, the electronic lock 100 can assist in determining whether the electronic lock 100 is in a locking state, a locking reset state, an unlocking state and an unlocking reset state through the Hall sensor 141, so that the control unit can accurately monitor the state of the electronic lock 100.

The knob 144 is pivotally arranged on the housing 143, and the knob 144 and the rotating shaft 111 are arranged on two sides of the housing 143, and the other end of the rotating shaft 111 is inserted into the knob 144, and the rotating shaft 111 is fixedly connected with the knob 144.
[0070] The user can twist the knob 144 to drive the rotating shaft 111, the lock core paddle 150 and the lock bolt 160 to rotate, so that the lock bolt 160 protrudes out of or retreats from the lock bolt slot, so that the electronic lock 100 is locked or unlocked. It can be understood that the electronic lock 100 can be locked or unlocked by physically rotating the knob 144. In this embodiment, it is recommended that the knob 144 and the rotating shaft 111 are integrally formed, but this should not be understood as a limitation of the present application.
[0071] In further embodiments, in combination with Figure 1 , Figure 9 , Figures 11 to 14 The knob 144 is provided with an indication line 145, the direction of the indication line 145 is the same as the direction of the locking surface 152 of the lock core paddle 150, and the knob 144 is fixedly arranged with the rotating shaft 111. When the lock core paddle 150 rotates, the lock bolt 160 protrudes into the lock bolt slot, and the locking surface 152 faces the lock bolt slot, the knob 144 also rotates synchronously with the rotating shaft 111, so that the indication line 145 also points to the lock bolt slot, to represent that the electronic lock 100 is in the locked state. Conversely, when the lock core paddle 150 rotates, so that the locking surface 152 is no longer directed to the lock bolt slot, the knob 144 is synchronously rotated, so that the indication line is also not directed to the lock bolt slot, to represent that the electronic lock 100 is in the unlocked state.

Bearing grooves 1433 are formed on the two sides of the bottom plate 1431, that is to say, the two bearing grooves 1433 are arranged on the inner side and the outer side of the bottom plate 1431, and the two bearing grooves 1433 are coaxially arranged with the pivot hole 1432.
[0073] The two bearing grooves 1433 are provided with bearings 147, the bearings 147 are tightly matched with the bearing grooves 1433, the bearings 147 are sleeved on the rotating shaft 111 and are tightly matched with the rotating shaft 111. Because the two bearings 147 are tightly matched with the bearing grooves 1433 and the rotating shaft 111, the rotating shaft 111 is tightly matched with the pivot hole 1432, so that the problem of shaking of the rotating shaft 111 during rotation is solved. In addition, because the bearings 147 exist between the knob 144 and the bottom plate 1431, the friction between the knob 144 and the bottom plate 1431 is not increased after the knob 144 is rotated, so that the rotation feeling of the knob 144 and the driving resistance of the motor are not affected, and the user experience is improved.
