Description

Technical Field

[0001] The invention belongs to the technical field of locks and relates to an embedded electromechanical lock body. Background Art

[0002] Traditional locks generally have a main bolt and a slant bolt on the lock body. When opening the door, first insert the key into the lock core, and then rotate the lock core to drive the main bolt and the slant bolt to move horizontally to unlock the door. When unlocking the door, the lock core rotates and drives the main bolt to move horizontally. After the main bolt returns to the lock body, it drives the slant bolt to move horizontally back into the lock body. Therefore, when unlocking the door, you need to turn the key several times continuously to complete the unlocking. It is impossible to achieve synchronous movement of the main bolt and the slant bolt, and the unlocking time is long.

[0003] The electronic unlocking part in the lock body is realized by a motor arranged in the lock body to realize the unlocking function. The motor is connected to the internal structure of the lock body through multiple gear sets to realize the unlocking function. When the gear set contacts the internal structure of the lock body and the motor is damaged during the unlocking process, the motor, the gear set and the internal structure of the lock body form a whole. The damaged motor locks the whole, and the door lock cannot be opened by an external key or an internal handle, which is inconvenient to use. Summary of the invention

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] 1. When the door is locked, if the motor is damaged and cannot be unlocked normally, you can turn the handle inside the door. When the handle is turned, it can drive the handle paddle and clutch paddle 1 to rotate synchronously, and at the same time drive the push piece and clutch block 1 to translate, so that clutch block 1 and clutch block 2 are relatively far apart and disengaged, so that the motor is separated from the gear pair transmission, and continue to turn the handle to unlock the door normally; outside the door, you can insert the key into the lock cylinder, turn the key to drive the lock cylinder dial wheel and clutch paddle 2 to rotate synchronously, and at the same time drive the push piece and clutch block 1 to translate, so that clutch block 1 and clutch block 2 are relatively far apart and disengaged, so that the motor is separated from the gear pair transmission, and continue to turn the key to unlock the door normally.

[0029] 2. When the lock core is rotated by the key, the lock core can drive the transmission gear to rotate synchronously, and drive the main lock tongue and the inclined tongue to move horizontally through the transmission mechanism 1 and the transmission mechanism 2 to lock or unlock, so as to achieve synchronous translation of the main lock tongue and the inclined tongue, saving the unlocking time. After unlocking, the main lock tongue is locked in the lock body to keep the unlocked state. After the key is pulled out, the lock core paddle can rotate in the opposite direction through the guide limit structure, so that the inclined tongue can extend out of the lock body to avoid the inclined tongue being locked.

Detailed implementation manners

[0047] The following are specific embodiments of the present invention and, in combination with the accompanying drawings, further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0048] As Figure 1 and Figure 6As shown in the figure, for the embedded electromechanical lock body of the present invention, a main lock tongue 32, a door handle, a lock core for inserting a key, and a motor 31 are provided inside the lock body 30. The motor 31 drives the main lock tongue 32 to translate for locking or unlocking through a transmission assembly. The transmission assembly includes a gear pair. A first clutch structure and a second clutch structure are also provided inside the lock body 30. When the door handle rotates, it can drive the motor 31 to be disengaged or connected to the gear pair transmission through the first clutch structure. When the key drives the lock core to rotate, it can drive the driving motor 31 to be disengaged or connected to the gear pair transmission through the second clutch structure. Both the first clutch structure and the second clutch structure include a first clutch block 55 movably arranged on the output shaft of the motor 31 and a second clutch block 56 fixedly connected to the input shaft of the gear pair. The first clutch structure further includes a first transmission structure in transmission connection with the door handle, and the second clutch structure further includes a second transmission structure in transmission connection with the lock core. Rotating the door handle through the first transmission structure or rotating the lock core through the second transmission structure can drive the first clutch block 55 to translate along the output shaft of the motor 31, so that the first clutch block 55 and the second clutch block 56 move relatively away to disengage or move relatively closer to engage.

[0049] As Figure 3 shown, the first transmission structure includes a door handle dial 57 and a first clutch dial 58 rotatably arranged inside the lock body 30, and a push plate 59 slidably arranged inside the lock body 30. The door handle dial 57 is coaxially arranged with the door handle and fixedly connected to the door handle. The door handle dial 57 abuts against the first clutch dial 58. When the door handle rotates, it can drive the door handle dial 57 and the first clutch dial 58 to rotate synchronously. The push plate 59 is axially slidably arranged along the output shaft of the motor 31 inside the lock body 30. The push plate 59 is fixedly connected to the first clutch block 55. The first clutch dial 58 abuts against the push plate 59. When the first clutch dial 58 rotates, it can drive the push plate 59 and the first clutch block 55 to translate back and forth.

[0050] A V-shaped fork 60 is provided on the first clutch dial 58. A V-shaped bayonet 61 is provided inside the V-shaped fork 60. A dial shaft 62 is fixedly arranged on the door handle dial 57. The dial shaft 62 is located inside the V-shaped bayonet 61. When the door handle dial 57 rotates, the dial shaft 62 slides back and forth along the V-shaped bayonet 61 and pushes the first clutch dial 58 to rotate. Arc-shaped bayonets 63 are respectively opened on the left and right sides of the first clutch dial 58. Two clutch convex shafts 64 are fixedly arranged on the push plate 59. The two clutch convex shafts 64 are respectively embedded in the two arc-shaped bayonets 63. The outer wheel surface of the clutch convex shaft 64 abuts against the side wall of the arc-shaped bayonet 63. When the first clutch dial 58 rotates, the first clutch dial 58 pushes the clutch convex shaft 64 to translate back and forth along the side wall of the corresponding arc-shaped bayonet 63.

[0051] As Figure 4 and Figure 5As shown, through the design of two clutch convex shafts 64 and the corresponding two arc-shaped bayonets 63, when the handle rotates left or right, it can drive one of the clutch convex shafts 64 to move through the clutch fork respectively, so that the push piece 59 and the first clutch block 55 translate back and forth.

[0052] As Figure 7 shown, the second transmission structure includes a lock core dial 53 and a second clutch dial 54 rotatably arranged in the lock body 30, and a push piece 59 slidably arranged in the lock body 30. The lock core dial 53 is coaxially arranged with the lock core and fixedly connected to the lock core. The lock core dial 53 abuts against the second clutch dial 54. When the handle rotates, it can drive the lock core dial 53 and the second clutch dial 54 to rotate synchronously; the push piece 59 is slidably arranged in the lock body 30 along the axial direction of the output shaft of the motor 31. The push piece 59 is fixedly connected to the first clutch block 55. The second clutch dial 54 abuts against the push piece 59. When the second clutch dial 54 rotates, it can drive the push piece 59 and the first clutch block 55 to translate back and forth.

[0053] A dial block 80 is fixedly arranged on the lock core dial 53. When the key drives the lock core to rotate, as Figure 8 shown, the dial block 80 on the lock core dial 53 rotates to abut against the second clutch dial 54 and pushes the second clutch dial 54 to rotate upward. An arc-shaped concave surface 82 is arranged on the second clutch dial 54. As Figure 9 shown, when the dial block 80 on the lock core dial 53 rotates to the arc-shaped concave surface 82, the arc-shaped concave surface 82 is coaxial with the lock core. During the process that the dial block 80 continues to rotate along the arc-shaped concave surface 82, the second clutch dial 54 remains stationary relative to the lock body 30. The purpose is to keep the first clutch block 55 and the second clutch block 56 separated when unlocking.

[0054] A plurality of limit slots 83 are arranged on the push piece 59. The opening direction of the limit slots 83 is consistent with the axial direction of the output shaft of the motor 38. A plurality of limit posts 84 corresponding to the positions of the limit slots 83 are fixedly arranged in the lock body 30. Each limit post 84 is respectively inserted into the corresponding limit slot 83. The second clutch dial 54 is rotatably arranged in the lock body 30 through a rotating shaft 81. A guiding slot 85 is also arranged on the second clutch dial 54. A guiding post 86 is fixedly arranged on the push piece 59. The guiding post 86 is inserted into the guiding slot 85. When the second clutch dial 54 rotates, it pushes the guiding post 86 to translate through the guiding slot 85.

[0055] The outer wall of the first clutch block 55 is provided with a positioning groove 65. A number of positioning protrusions 66 are fixedly arranged on the pushing piece 59. The positioning protrusions 66 are clamped in the positioning groove 65 so that the pushing block moves synchronously with the first clutch block 55. One end face of the first clutch block 55 facing the second clutch block 56 is provided with a rotation stopping groove 67. One end face of the second clutch block 56 facing the first clutch block 55 is fixedly provided with a rotation stopping protrusion 68. The shape of the rotation stopping protrusion 68 is adapted to the shape of the rotation stopping groove 67. The rotation stopping protrusion 68 is inserted into the rotation stopping groove 67 so that the first clutch block 55 and the second clutch block 56 rotate synchronously.

[0056] As Figure 2 shown, the gear pair includes a driving bevel gear 69 fixedly connected to the second clutch block 56, a driven bevel gear 70 meshing with the driving bevel gear 69, a first transmission gear 71 fixedly connected to the driven bevel gear 70, a second transmission gear 72 meshing with the first transmission gear 71, and a shifting rod 76 rotating coaxially with the second transmission gear 72. A first transmission shaft 73 and a second transmission shaft are fixedly arranged on the second transmission gear 72. A first transmission groove 74 is formed on the main locking tongue 32. A second transmission groove 75 is formed on the second transmission gear 72. The first transmission shaft 73 and the second transmission shaft are respectively inserted into the first transmission groove 74 and the second transmission groove 75. The motor 36 drives the driving bevel gear 69, the driven bevel gear 70, the first transmission gear 71 and the second transmission gear 72 to rotate. When the second transmission groove 75 rotates to abut against the second transmission shaft and pushes the shifting rod 76 to rotate, the first transmission shaft 73 abuts against the first transmission groove 74 and pushes the main locking tongue 32 to translate along the first transmission groove 74.

[0057] As Figure 10 and Figure 11 shown, a diagonal tongue 103 is further arranged on the lock body 30. A transmission gear 104 is rotatably arranged in the lock body 30. A first transmission mechanism is arranged between the transmission gear 104 and the main locking tongue 32. A second transmission mechanism is arranged between the transmission gear 104 and the diagonal tongue 103. When the key drives the lock core to rotate, the lock core can drive the above-mentioned transmission gear 104 to rotate synchronously, drive the main locking tongue 32 to translate horizontally for locking or unlocking through the first transmission mechanism, and drive the diagonal tongue 103 to translate horizontally for locking or unlocking through the second transmission mechanism.

[0058] As Figure 12 and Figure 13 shown, the first transmission mechanism includes a shifting tooth 105 rotatably arranged in the lock body 30, a first transmission shaft 73 fixedly arranged on the shifting tooth 105, and a first transmission groove 74 formed on the main locking tongue 32. The shifting tooth 105 meshes with the transmission gear 104. The first transmission shaft 73 is inserted into the first transmission groove 74. When the transmission gear 104 rotates, it drives the shifting tooth 105 to rotate synchronously. The main first transmission shaft 73 pushes the main locking tongue 32 to translate along the first transmission groove 74.

[0059] The second transmission mechanism includes a bevel tongue dial 113 and a lock core dial 112 rotatably arranged in the lock body 30, and a push bar 108 slidably arranged in the lock body 30. A first fork 109 and a second fork 110 are arranged on the bevel tongue dial 113, and a third fork 111 is arranged on the lock core dial 112. The lock core dial 112 rotates coaxially with the above-mentioned transmission gear 104. When the transmission gear 104 rotates, it drives the lock core dial 112 to rotate synchronously, so that the third fork 111 abuts against the push bar 108 and pushes the push bar 108 to translate forward. The second fork 110 abuts against the push bar 108, and the push bar 108 drives the second fork 110 and the bevel tongue 103 fork to rotate, so that the first fork 109 pushes the bevel tongue 103 to translate and retract into the lock body 30.

[0060] As Figures 14 to 16 shown, a guiding and limiting structure is further arranged between the transmission gear 104 and the lock core dial 112. The guiding and limiting structure includes a limiting piece 114 fixed in the lock body 30, two limiting pins 117 fixed on the transmission gear 104, a first limiting arc groove 115 opened on the limiting piece 114, and a second limiting arc groove 116 opened on the lock core dial 112. Both the first limiting arc groove 115 and the second limiting arc groove 116 are opened with the lock core as the center and have the same arc length. The limiting pins 117 sequentially pass through the second limiting arc groove 116 and the first limiting arc groove 115. When the key drives the lock core to rotate, the transmission gear 104 and the lock core dial 112 rotate clockwise along the first limiting arc groove 115 synchronously. After the key is pulled out, the lock core dial 112 can rotate counterclockwise relative to the transmission gear 104 along the second limiting arc groove 116 until the second limiting arc groove 116 abuts against the limiting pin 117. A blocking piece 121 perpendicular to the lock core dial 112 is further fixed on the lock core dial 112. When the lock core rotates to abut against the blocking piece 121 and pushes the blocking piece 121 to rotate, one side of the transmission gear 104 abuts against the blocking piece 121. When the lock core dial 112 rotates, it drives the transmission gear 104 to rotate synchronously through the blocking piece 121.

[0061] The push bar 108 is longitudinally slidably arranged in the lock body 30. A plurality of guiding long grooves 122 are opened on the push bar 108, and a plurality of guiding pins 123 corresponding to the positions of the guiding long grooves 122 one by one are fixed in the lock body 30. Each guiding pin 123 is respectively inserted into the corresponding guiding long groove 122. A first baffle 124 and a second baffle 125 perpendicular to the push bar 108 are fixed on the push bar 108. The first baffle 124 and the second baffle 125 are arranged in parallel and spaced apart longitudinally. The third fork abuts against the first baffle 124, and the second fork 110 abuts against the second baffle 125. When the lock core dial 112 rotates or the bevel tongue dial 113 rotates, it can push the push bar 108 to translate through the first baffle 124 or the second baffle 125.

[0062] A guide seat 118 is fixedly arranged inside the lock body 30. The oblique bolt 103 is slidably arranged on the guide seat 118 through a guide rod 119. A reset spring 120 is sleeved on the guide rod 119 and is used to push the oblique bolt 103 to extend out of the lock body 30. A push plate 126 is fixedly arranged on the guide rod 119. The first fork 109 abuts against the push block. When the oblique bolt fork rotates, the push plate 126, the guide rod 119 and the oblique bolt 103 are pushed to translate through the first fork 109.

[0063] The working principle of the present invention is as follows:

[0064] When unlocking, when the key drives the lock core to rotate clockwise, the lock core can drive the transmission gear 104 to rotate clockwise. The transmission gear 104 drives the tooth pick 105 to rotate counterclockwise. The main transmission shaft one 73 pushes the main lock tongue 32 to translate and retract into the lock body 30 along the transmission groove one 74. The lock core dial 112 rotates clockwise synchronously with the transmission gear 104 until the third fork 111 abuts against the first baffle 124 and pushes the push bar 108 to move downward, so that the second baffle 125 pushes the second fork 110 and the oblique bolt fork to rotate clockwise. The first fork 109 pushes the push plate 126, the guide rod 119 and the oblique bolt 103 to translate and retract into the lock body 30.

[0065] After unlocking, the main lock tongue 32 is locked in the lock body 30 to maintain the unlocked state. After the key is pulled out, the position of the transmission gear 104 remains unchanged. The reset spring 120 pushes the oblique bolt 103 to extend out of the lock body 30. The push plate 126 pushes the first fork 109 and the oblique bolt dial 113 to rotate counterclockwise. The second fork 110 pushes the push bar 108 to move upward and drives the third fork 111 and the lock core dial 112 to rotate counterclockwise. The lock core dial 112 rotates counterclockwise relative to the transmission gear 104 along the limiting arc groove two 116 until the inner wall of the limiting arc groove two 116 abuts against the limiting pin 117 and the lock core dial 112 stops rotating. At this time, the outer ring of the oblique bolt 103 extends out of the lock body 30.
