[0021] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0022] like Figures 1 to 7As shown, a compact mechanical and electronic dual-purpose ball lock comprises a front ball lock body 1, a rear ball lock body 2 and a transmission rod assembly 3 connected between the front and rear ball lock bodies 2, wherein the front ball lock body 1 comprises a front shell body 4, wherein a lock core structure 5 and a clutch structure 6 are arranged in the front shell body 4, wherein the clutch structure 6 is driven by the lock core structure 5 to cooperate with the transmission rod assembly 3 in transmission, wherein the lock core structure 5 comprises a lock core assembly, wherein the output end of the lock core assembly is driven to be connected to a push block 7 which is slidably arranged; wherein the clutch structure 6 comprises a clutch head 8 and a clutch plate 9, wherein the clutch head 8 is fixedly connected to one end of the transmission rod assembly 3, wherein the clutch plate 9 is slidably connected to one side of the push block 7, and a transmission lever 10 is arranged between the push block 7 and the clutch plate 9, wherein the push block 7 pushes the transmission lever 10 to move, thereby causing the clutch plate 9 to move toward the clutch head 8 and be in transmission engagement with the clutch head 8.

[0023] This ball lock is driven by a transmission lever 10, so that the movement directions of the push block 7 and the clutch plate 9 can be set horizontally to each other, so that the lock core structure 5 is adjacent to one side of the clutch structure 6, making the front ball lock body more compact. In addition, the transmission lever 10 is swung to the free gap 4 between the push block 7, the clutch plate 9 and the front shell body, so that the transmission structure does not occupy the axial space of the front ball lock body 1, which helps to further reduce the size of the front ball lock body.

[0024] The transmission lever 10 is in a crank arm structure and includes a first swing arm 1001 and a second swing arm 1002. A rotating shaft fulcrum 1003 for swinging hinge is provided between the first swing arm 1001 and the second swing arm 1002. The first swing arm 1001 movably contacts the outer side of the push block 7, and the second swing arm 1002 movably contacts the outer side of the clutch plate 9. The transmission lever 10 in a crank arm structure can fit the curvature of the front shell body 4, so that the transmission lever 10 can make full use of the free space 4 between the push block 7, the clutch plate 9 and the front shell body, making the front ball lock body 1 more compact.

[0025] The lock core assembly includes a mechanical lock core 11 and a motor 12 that are adjacent to each other, and a push block seat 71 that slides linearly is connected to the rotating shaft 121 of the motor 12, and the push block 7 is connected to the push block seat 71 and is placed between the mechanical lock core 11 and the first swing arm 1001; a cavity 72 is provided in the push block seat 71, and a first spring 13 that is sleeved on the outside of the rotating shaft 121 is provided in the cavity 72, and a pressure rod 122 is provided on the rotating shaft 121, which rotates with the first spring 13 to form a screw rod.

[0026] When the above structure is in use, the front ball lock body 1 receives the unlocking command, and the motor 12 works to drive the rotating shaft 121 to drive the pressure rod 122 to rotate, and the first spring 13 fixed in the cavity 72 immediately cooperates with the pressure rod 122 to form a screw rod, gradually pushing the first spring 13 to the side away from the motor 12. When the first spring 13 is compressed and the elastic potential energy increases, the first spring 13 pushes the push block seat 71 and the push block 7 to move toward the first swing arm 1001 and pushes the first swing arm 1001 to swing outward, so that the second swing arm 1001 swings inward and pushes the clutch plate 9 to move horizontally and insert into the clutch head 8 to complete the engagement with the transmission rod assembly 3, so that the door can be opened smoothly when the front ball lock body 1 is turned; and when the ball lock has no power or the user uses the key to open the door, the key turns the mechanical lock core 11, the lock tongue of the mechanical lock core 11 moves axially and directly pushes the push block 7, so that the push block 7 can push the first swing arm 1001 horizontally.

[0027] In addition, a lock hole 403 suitable for inserting a key is provided on the front housing 4 corresponding to the mechanical lock core 11 .

[0028] The clutch head 8 is provided with a clutch groove 801 suitable for the clutch plate 9 to be inserted into or removed from, the front housing 4 is provided with a guide groove 401 corresponding to the clutch groove 801, the outer end of the clutch plate 9 is provided with two limit parts 91 which are guided and matched with the guide groove 401, two second springs 14 which are arranged on both sides of the clutch plate 9 and abut against between the guide groove 401 and the limit parts 91, the second springs 14 abut against between the guide groove 401 and the limit parts 91, the clutch plate 9 elastically slides in the guide groove 401 through the second springs 14, the guide groove 401 can ensure that the clutch plate 9 can slide in a straight line, and the clutch plate 9 is extended with a contact 92 which abuts against the second swing arm 1002;

[0029] After the front ball lock body 1 receives the door locking command, the motor 12 drives the rotating shaft 121 to rotate and drives the pressure rod 122 to rotate in the opposite direction, gradually pushing the first spring 13 to the side close to the motor 12. When the first spring 13 is compressed and the elastic potential energy increases to the other side, the first spring 13 pushes the push block seat 71 to move in the direction of the motor and makes the push block 7 leave the first swing arm 1001. After the transmission lever 10 withdraws the force of the lock core assembly, the elastic potential energy previously stored by the second spring 14 when unlocking is released, pushing the clutch plate 9 to leave the clutch slot 801 and engage with it. At the same time, the sliding clutch plate 9 pushes the second swing arm 1002 horizontally again, thereby resetting the transmission lever 10, and the above-mentioned contact 92 is convenient to maintain contact with the second swing arm 1002.

[0030] The front shell body 4 is fastened to the support base 15, and the support base 15 is provided with a lock core cavity 151 for installing the mechanical lock core 11, a motor cavity 152 for installing the motor 12, a slide groove 153 suitable for the linear sliding of the push block seat 71, an axle seat 154 for being hinged to the rotating shaft fulcrum 1003, and a battery cavity 155 for installing the battery 16, and a cover plate 17 is fastened to the top of the support base 15, and the mechanical lock core 11, the motor 12, the push block 7, the push block seat 71 and the transmission lever 10 are fixed to the support base 15 through the cover plate 17, and a clearance hole 171 is also provided on the cover plate 17 corresponding to the first swing arm 1001, and the above-mentioned structure can be fixed in the corresponding cavity through the assembly connection of the cover plate 17 and the support base 15, so that the assembly is simple and the production efficiency can be improved.

One end of the transmission rod assembly 3 is connected to a positioning block 19 that is in dynamic contact with the first position sensing switch 181 and the second position sensing switch 182.

[0032] The positioning block 19 is an eccentric structure, one end of which is connected to the transmission rod assembly 3, and the other end corresponds to three sensing positions at 9 o'clock, 12 o'clock and 3 o'clock respectively. When the positioning block 19 is opened to 9 o'clock, the positioning block 19 triggers the first position sensing switch 181, and the ball lock is in a normally open state (if it is not locked, you can enter and exit at any time by turning the front ball lock body 1). When it is opened to 3 o'clock, the positioning block 19 triggers the second position sensing switch 182, and the ball lock is in an anti-lock state (after returning to the lock, only the administrator's fingerprint or password can unlock it, and the fingerprint or password of ordinary users cannot open it); when the positioning block 19 is opened at the 12 o'clock position, both position sensing switches cannot detect. At this time, after the door is closed, the lock is automatically locked (at this time, the front ball lock body 1 is idling, but the rear ball lock body 2 can be opened at any time).
