[0049] In order to facilitate those skilled in the art to understand the present invention, the present invention will be further described below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0050] Figures 1 to 9 An electric lock body of the present invention is schematically shown.

[0051] like Figures 1 to 9 As shown, an electric lock body of the present invention includes a housing 11, a latch bolt transmission structure and a square bolt transmission structure: the latch bolt transmission structure is arranged on the housing 11, including an inner handle shaft 18, an outer handle shaft 17 and a latch bolt transmission sub-mechanism, the inner handle shaft 18 and the outer handle shaft 17 respectively drive the latch bolt transmission sub-mechanism, and the inner handle shaft 18 is provided with a square bolt shift block 182; the square bolt transmission structure is arranged on the housing 11; the square bolt transmission structure includes a square bolt 21, a mechanical cam 22, a reduction mechanical assembly 24 and a square lock transmission gear 23; the square bolt 21 is slidably connected to the housing 11, one section of the square bolt 21 is a protruding portion 211, and the other section is a linkage portion 212, and the linkage portion 212 is provided with an air avoidance gap 2 16 and the toggle slot 215; the mechanical cam 22 is rotatably connected to the housing 11, and a swing arm 221 protruding outward is provided on the outer side of the middle part of the mechanical cam 22, and a transmission protrusion 222 is provided on the upper part of the mechanical cam 22. The lower part of the swing arm 221 is movably inserted into the toggle slot 215, and the upper part of the swing arm 221 abuts against the square tongue toggle block 182; the reduction mechanical assembly 24 is connected to the housing 11, and the output part is the output gear 241; the square lock transmission gear 23 is sleeved on the upper part of the mechanical cam 22, and an arc groove 231 is provided along the circumference of the mechanical cam 22, the transmission protrusion 222 is located in the arc groove 231, and the square lock transmission gear 23 is engaged with the output gear 241 of the reduction mechanical assembly 24.

[0052] Specifically, the electric lock body can drive the square lock transmission gear 23 through the electric reduction mechanical assembly 24, and the square lock transmission gear 23 drives the mechanical cam 22, and the mechanical cam 22 drives the square lock tongue 21 to realize the extension and retraction of the square lock tongue 21. Since the square lock transmission gear 23 is provided with an arc groove 231, the square lock transmission gear 23 and the mechanical cam 22 can rotate relative to each other. When a mechanical key is used or the main lock tongue is turned, the gear train and motor in the reduction mechanical assembly 24 can be avoided from rotating in the reverse direction, thereby solving the problem of large resistance when the electric lock body uses a mechanical key or turns the main lock tongue.

[0053] It should be noted that in some embodiments, relative to the lower part of the swing arm 221, the upper part of the swing arm 221 is provided with a clearance groove 2211 adapted to the square tongue block 182, so that the swing arm 221 has a step, so that deformation and dislocation are not easily caused when the square tongue block 182 moves the swing arm 221.

[0054] It should be noted that, in some embodiments, a square tongue positioning hole 213 is provided on the side surface of one end of the protruding portion 211 close to the linkage portion 212, and the square lock tongue 21 is inserted into the square tongue guide hole 112. In some embodiments, the square tongue guide hole 112 only serves to reduce the weight of the square lock tongue 21 and reduce the material consumption; in some embodiments, the edge of the square tongue positioning hole 213 is provided with a guiding slope.

[0055] Furthermore, in some embodiments, the square tongue transmission structure further includes a rotation positioning mechanism; the rotation positioning mechanism is electrically connected to the reduction mechanical assembly 24 and is used to check whether the square lock transmission gear 23 rotates to a set position.

[0056] Specifically, when the square lock transmission gear 23 is checked to reach the set position representing that the square lock tongue 21 is extended or retracted to the set length, a stop signal is sent to the reduction mechanical assembly 24 to stop the reduction mechanical assembly 24; in some embodiments, there are multiple set positions, each representing a different position of the square lock tongue 21; in some embodiments, the set position can be one, and when it is detected that the square lock transmission gear 23 rotates to the set position, the reduction mechanical assembly 24 can be controlled according to the judgment result and the preset rules, for example, the reduction mechanical assembly 24 is controlled to stop, so that the reduction mechanical assembly 24 can be controlled more accurately, thereby avoiding idling of the reduction mechanical assembly 24 and accurately positioning the relative position of the transmission gear 23 and the mechanical cam 22.

[0057] Furthermore, in some embodiments, the rotation positioning mechanism includes a magnet 252 provided on the square lock transmission gear 23 and a gear detection switch plate 251 for monitoring the position of the magnet 252 ; the gear detection switch plate 251 is electrically connected to the reduction mechanical assembly 24 .

[0058] Specifically, the rotational position of the square lock transmission gear 23 can be determined by detecting the magnet 252 through the gear detection switch plate 251, and a signal is fed back to the deceleration mechanical assembly 24 through the gear detection switch plate 251. For example, when the square lock tongue 21 retracts, after the gear detection switch plate 251 detects the magnet 252, a signal is sent to the deceleration mechanical assembly 24 to stop the deceleration mechanical assembly 24.

[0059] Furthermore, in some embodiments, the square tongue transmission structure further includes a square tongue position detection structure, which is provided on the housing 11 and is used to check the position of the square tongue 21 .

[0060] Specifically, the square lock tongue position detection structure detects whether the square lock tongue 21 reaches the set position, and then controls the deceleration mechanical component 24 to achieve the effect of automatically controlling the square lock tongue 21.

[0061] Furthermore, in some embodiments, the square lock tongue position detection structure includes a position detection switch plate 26 provided on the housing 11 and a thin sheet 214 provided on the side wall of the extension portion 211; the position detection switch plate 26 includes an extended position detection switch 261 and a retracted position detection switch 262; the extended position detection switch 261 and the retracted position detection switch 262 are used to detect whether the thin sheet 214 has reached its detection position.

[0062] Specifically, when the square lock tongue 21 moves, the thin sheet 214 moves synchronously with it; when the extended into position detection switch 261 detects the thin sheet 214, it means that the square lock tongue 21 has been extended into position and the deceleration mechanical assembly 24 can be stopped; when the retracted into position detection switch 262 is activated, it means that the square lock tongue 21 has been retracted into position and the deceleration mechanical assembly 24 can be stopped.

[0063] Furthermore, in some embodiments, the square tongue transmission structure further includes a square lock tongue torsion spring 27 , one end of the square lock tongue torsion spring 27 is fixedly connected to the housing 11 , and the other end is connected to the mechanical cam 22 .

[0064] Specifically, the square lock tongue torsion spring 27 is used to play a positioning role, which is a prior art and will not be described in detail here.

[0065] Furthermore, in some embodiments, the oblique bolt transmission structure includes an oblique bolt 12, a transmission bar 13, a transmission wheel 14, a spring positioning member 16, an oblique bolt spring 15, an inner handle shaft 18 and an outer handle shaft 17; the oblique bolt transmission sub-mechanism includes an oblique bolt 12, a transmission bar 13, a transmission wheel 14, a spring positioning member 16 and an oblique bolt spring 15; the oblique bolt 12 is slidably connected to the housing 11 and is provided with a first transmission rack 121; the transmission bar 13 is slidably connected to the housing 11 and is provided with a second transmission rack 131 and a toggle protrusion 132; the transmission wheel 14 is provided between the oblique bolt 12 and the transmission bar 13, and the transmission wheel 1 4 are respectively engaged with the first transmission rack 121 and the second transmission rack 131; the spring positioning member 16 is fixedly connected to the housing 11 and is rotatably connected to the transmission wheel 14; the two ends of the oblique lock tongue spring 15 respectively abut the spring positioning member 16 and the oblique lock tongue 12; the inner handle shaft 18 is rotatably connected to the housing 11 and is provided with an inner handle toggle block 181; the outer handle shaft 17 is rotatably connected to the housing 11 and is provided with an outer handle toggle block 171; the inner handle shaft 18 and the outer handle shaft 17 are rotatable relative to each other, and the inner handle toggle block 181 and the outer handle toggle block 171 are located on the side of the toggle protrusion 132 away from the second transmission rack 131.

[0066] Specifically, the oblique lock tongue spring 15 provides a thrust to make the oblique lock tongue 12 partially extend out of the shell 11, and under the drive of external force, the inner handle toggle block 181 of the inner handle shaft 18 or the outer handle toggle block 171 of the outer handle shaft 17 drives the transmission bar 13, and the transmission bar 13 drives the transmission wheel 14 to rotate, thereby driving the oblique lock tongue 12 to slide, thereby realizing the contraction of the oblique lock tongue 12. The transmission structure is compact, and the oblique lock tongue 12 is driven by a gear rack transmission method. The transmission wheel 14 is arranged between the oblique lock tongue 12 and the transmission bar 13. The transmission wheel 14 is subjected to balanced force and stable transmission. The sliding shaking of the oblique lock tongue 12 is small, which solves the problem of large transmission shaking of the oblique lock tongue transmission structure of the lock body.

[0067] It should be said that in some embodiments, the sliding connection between the oblique lock tongue 12 and the housing 11, and the sliding connection between the transmission bar 13 and the housing 11 can be achieved by providing a sliding groove or sliding hole on the housing 11, and correspondingly providing a guide protrusion on the oblique lock tongue 12 and the transmission bar 13, the guide protrusion being inserted into the sliding groove or sliding hole and moving along the sliding groove or sliding hole.

[0068] It should be noted that, in some embodiments, the spring locator 16 and the housing 11 are plugged together, and the spring locator 16 and the housing 11 can be fixed with the aid of screws.

[0069] It should be noted that, in some embodiments, the spring positioning member 16 is provided with a protruding rib on the side facing the transmission wheel 14 for limiting the transmission wheel 14 .

[0070] It should be noted that in some embodiments, the oblique bolt 12 is provided with an oblique bolt positioning hole 122, which is located on the oblique surface of the oblique bolt 12 at one end near the first transmission rack 121. In some embodiments, the oblique bolt positioning hole 122 merely serves to reduce the weight of the oblique bolt 12 and reduce material requirements; in some embodiments, the edge of the oblique bolt positioning hole 122 is provided with a guiding bevel.

[0071] Furthermore, the oblique lock tongue 12 is provided with a transmission bar avoidance notch 216 corresponding to the transmission bar 13. This can make the structure more compact and conveniently reduce the volume.

[0072] Furthermore, in some embodiments, the spring positioning member 16 includes a spring positioning cylinder 161, and one end of the oblique lock tongue spring 15 is sleeved on the outside of the spring positioning cylinder 161; a spring positioning hole 124 is provided on the oblique lock tongue 12, and the other end of the oblique lock tongue spring 15 is inserted into the spring positioning hole 124.

[0073] Specifically, the spring positioning cylinder 161 and the spring positioning hole 124 can better fix the oblique lock tongue spring 15, so that the electric lock body can work stably.

[0074] Furthermore, in some embodiments, the spring positioning member 16 further includes a fixing cylinder 162 ; a waist-shaped hole 143 is provided on the transmission wheel 14 , and the fixing cylinder 162 is inserted into the waist-shaped hole 143 .

[0075] Specifically, due to the length limitation of the waist-shaped hole 143 , the fixed cylinder 162 can limit the rotation angle of the transmission wheel 14 , and further limit the moving distance of the oblique locking tongue 12 .

[0076] Furthermore, in some embodiments, the transmission wheel 14 is provided with a first gear tooth portion 141 and a second gear tooth portion 142; the first gear tooth portion 141 is engaged with the first transmission rack 121; the second gear tooth portion 142 is engaged with the second transmission rack 131; and a distinguishing mark is also provided on the transmission wheel 14 for distinguishing the first gear tooth portion 141 and the second gear tooth portion 142.

[0077] Specifically, a spacing area without gear teeth can be set between the first gear tooth portion 141 and the second gear tooth portion 142, which can reduce the weight and material of the transmission wheel 14, more accurately determine the initial position of engagement, and cooperate with the distinguishing mark to facilitate the assembly of the transmission wheel 14.

[0078] Furthermore, in some embodiments, the oblique lock tongue 12 is provided with a first limiting plate 123 on one side of the first transmission rack 121 ; the transmission bar 13 is provided with a second limiting plate 133 on one side of the second transmission rack 131 .

[0079] Specifically, the first limiting plate 123 and the second limiting plate 133 are arranged on the same side of the transmission wheel 14, and are used to limit the transmission wheel 14 to prevent the transmission wheel 14 from disengaging from the first transmission rack 121 and the second transmission rack 131 in this direction, so that the inclined tongue transmission structure works stably.

[0080] Furthermore, in some embodiments, a cylindrical protrusion 172 is provided on the outer handle shaft 17 ; a positioning hole 182 is provided on the inner handle shaft 18 , and the cylindrical protrusion 172 is inserted into the positioning hole 182 .

[0081] Specifically, the outer handle shaft 17 and the inner handle shaft 18 are coaxially arranged, and by inserting the cylindrical protrusion 172 into the positioning hole 182, the inner handle toggle block 181 and the outer handle toggle block 171 can have substantially the same toggle effect on the toggle protrusion 132.

[0082] Furthermore, in some embodiments, a dialing surface 1321 that is inclined toward the inner handle shaft 18 and the outer handle shaft 17 is provided on the dialing protrusion 132 .

[0083] Specifically, the inclined toggle surface 1321 can increase the contact area, reduce the friction of the contact surface, reduce the wear intensity of the inner handle toggle block 181 and the outer handle toggle block 171, and increase the service life of the inclined tongue transmission structure.

[0084] Furthermore, in some embodiments, the inner handle toggle block 181 and the outer handle toggle block 171 have the same shape; the inner handle toggle block 181 is provided with a slot on the side facing the toggle surface 1321; the free end of the inner handle toggle block 181 is a rounded structure at least on the side facing the toggle protrusion 132.

[0085] Specifically, in the same way, the outer handle toggle block 171 is provided with a slot 1711 on the side facing the toggle surface 1321, and one end of the toggle protrusion 132 and the toggle surface 1321 are adapted to be inserted into the slot, so that the toggle protrusion 132 is tightly fitted with the inner handle toggle block 181 and the outer handle toggle block 171, so that the toggle protrusion 132 responds sensitively to the toggle of the inner handle toggle block 181 or the outer handle toggle block 171, thereby improving the accuracy of the use of the oblique tongue transmission structure and making it more comfortable to use; the free end of the inner handle toggle block 181 is a rounded structure at least on the side facing the toggle protrusion 132, which can reduce wear on the toggle protrusion 132 when toggling.

[0086] Furthermore, in some embodiments, a weight-reducing groove 1322 is provided on the driving protrusion 132 along the axial direction.

[0087] Specifically, the weight-reducing groove 1322 can reduce the weight of the toggle protrusion 132, making the total weight of the electric lock body lighter; in some embodiments, a flexible material that acts as a buffer is provided in the weight-reducing groove 1322, such as a sponge, which is used to act as a buffer when the toggle protrusion 132 is toggled, thereby preventing hard materials from directly interfering with the shell 11, thereby increasing the comfort and service life of the electric lock body.

[0088] The electric lock body of the present invention can drive the square lock transmission gear 23 through the electric reduction mechanical component 24, and the square lock transmission gear 23 drives the mechanical cam 22, and the mechanical cam 22 drives the square lock tongue 21 to realize the extension and retraction of the square lock tongue 21. Since the square lock transmission gear 23 is provided with an arc groove 231, the square lock transmission gear 23 and the mechanical cam 22 can rotate relative to each other. When a mechanical key is used or the main lock tongue is turned, the gear train and motor in the reduction mechanical component 24 can be avoided from being rotated in the reverse direction. This solves the problem that when the electric lock body uses a mechanical key or the main lock tongue is turned, the gear train and motor in the reduction mechanical component 24 need to be rotated in the reverse direction, which causes large resistance and causes certain damage or destruction to the reduction motor.

[0089] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, which all fall within the scope of protection of the present invention.
