Those skilled in the art can reasonably determine the specific meanings of the above words in the present invention in combination with the specific content of the technical solution.

[0033] Reference Figures 1 to 4 The electric ball lock of the embodiment of the present invention comprises: a front ball lock body 100, wherein the front ball lock body 100 comprises a front sleeve 110 and a front ball shell 120 connected to one end of the front sleeve 110; a rear ball lock body 200; a connecting rod 300, one end of which is connected to the rear ball lock body 200, and the other end of which is connected to a first clutch member 310 located in the front sleeve 110; a second clutch member 111, which is disposed in the front sleeve 110 and can move relative to the first clutch member 310 and engage with the first clutch member 111; The first clutch member 310 is connected or separated from the second clutch member 310; the electric clutch mechanism 400 is arranged in the front ball shell 120, and is used to drive the first clutch member 310 and the second clutch member 111 to slide relative to each other along the front sleeve 110 so that the two are connected or separated; the mechanical lock core 500 is arranged in the front ball shell 120, and the output end of the mechanical lock core 500 can drive the first clutch member 310 to slide along the front sleeve 110 and connect or separate with the second clutch member 111.

[0034] The electric ball lock of the above structure uses the front sleeve 110 to set the first clutch member 310 and the second clutch member 111 that cooperate with each other, and the electric clutch mechanism 400 and the mechanical lock core 500 are placed in the front ball shell 120. The electric clutch mechanism 400 or the mechanical lock core 500 drives the first clutch member 310 and the second clutch member 111 to slide relative to each other to achieve connection or separation, so that the electric ball lock is simple in structure, the volume redundancy in the front ball shell 120 is high, the precision requirements of parts are low, the cost is reduced, and the problems of precision and fragility of parts, difficulty in processing and installation can be avoided. The appearance of the front ball shell 120 will not be bloated due to the complex structure, which is conducive to achieving the diversity of the appearance of the ball lock.

[0035] See also Figure 2 , Figure 3 and Figure 4In some embodiments of the present invention, the connecting rod 300 can slide back and forth along the length direction of the front sleeve 110, the second clutch 111 is a strip protrusion or an embedding slot 320 formed on the inner peripheral wall of the front sleeve 110 and extending along the length direction of the front sleeve 110, the first clutch 310 is provided with an embedding slot 320 matched with the strip protrusion or a strip protrusion matched with the embedding slot 320, and the first clutch 310 is connected with an elastic member 600 for driving the embedding slot 320 away from the strip protrusion. In this embodiment, the second clutch 111 is a strip protrusion, and accordingly, the embedding slot 320 is provided on the first clutch 310, and there are two strip protrusions and embedding slots 320, which is conducive to improving the stability and reliability of the combination of the first clutch 310 and the second clutch 111. When the strip protrusion is inserted into the embedding slot 320, torque can be transmitted between the connecting rod 300 and the front sleeve 110.

[0036] In the unlocked state, the elastic member 600 drives the first clutch member 310 to move so that the insertion slot 320 leaves the strip-shaped protrusion. At this time, the user holds the front ball shell 120 to rotate, and the front sleeve 110 rotates relative to the connecting rod 300. The front ball lock body 100 cannot drive the connecting rod 300 to rotate and cannot be unlocked. When unlocking is required, the electric clutch mechanism 400 or the mechanical lock core 500 drives the first clutch member 310 to move in the direction of overcoming the action of the elastic member 600, so that the insertion slot 320 and the strip-shaped protrusion are combined. At this time, rotating the front ball shell 120 can drive the connecting rod 300 and the rear ball lock body 200 to rotate together, thereby unlocking the lock tongue assembly of the linkage connecting rod 300. In addition, the second clutch member 111 is formed on the inner peripheral wall of the front sleeve 110, and no additional parts are required, which is conducive to further simplifying the clutch structure of the electric ball lock. It should be noted that the connecting rod 300 can slide back and forth within a certain stroke range along the length direction of the front sleeve 110, but when the connecting rod 300 rotates, it can also drive the rear ball lock body 200 to rotate. Specifically, the cross-section of the connecting rod 300 is square, and accordingly, the rear ball lock body 200 is provided with a square hole for the connecting rod 300 to telescopically slide.

[0037] Of course, in other embodiments, the connecting rod 300 can also be set to be fixed relative to the rear ball lock body 200, that is, the first clutch member 310 is fixed, and the second clutch member 111 is set to be a movable member that can only be slid within the front sleeve 110, and the movable member cannot rotate relative to the front sleeve 110 to ensure the transmission of torque.

[0038] See also Figure 3 , Figure 5 and Figure 6In some embodiments of the present invention, the electric clutch mechanism 400 includes a rotating sleeve 410 rotatably disposed at one end of the front sleeve 110 close to the front ball shell 120 and a driving assembly driving the rotating sleeve 410 to rotate. A driving member 420 is slidably disposed in the rotating sleeve 410. When the rotating sleeve 410 rotates, it can drive the driving member 420 to move in the direction of compressing the elastic member 600 so that the embedding slot 320 is combined with the strip-shaped protrusion. It should be noted that if the electric clutch mechanism 400 adopts a reciprocating linear motion along the length direction of the front sleeve 110, the length of the front ball shell 120 needs to be set to a relatively slender outer dimension to meet the travel of the reciprocating linear motion and the installation requirements, resulting in the appearance of the front ball lock body 100 being limited, the aesthetics being insufficient, and the gripping feeling being poor. The electric clutch mechanism 400 of the above structure uses the rotation of the rotating sleeve 410 to link the driving member 420 to slide close to the first clutch member 310, thereby driving the first clutch member 310 and the second clutch member 111 to combine, and the output end of the mechanical lock core 500 can also extend from the end of the rotating sleeve 410 to push the driving member 420 close to the first clutch member 310, which is beneficial to shorten the length of the front ball shell 120, and the internal space of the front ball shell 120 is more spacious, and the front ball shell 120 can be designed to be short.

[0039] See also Figure 3 , Figure 4 and Figure 6 In some embodiments of the present invention, an annular mounting plate 112 is provided at one end of the front sleeve 110 close to the front ball shell 120. The front ball shell 120 is assembled to the annular mounting plate 112 by a plurality of bolts to enclose a receiving space connected to the rotating sleeve 410. The receiving space is used to accommodate the electric clutch mechanism 400, the mechanical lock cylinder 500, the identification module 800, the control circuit board, etc. The mechanical lock cylinder 500 includes a lock shell 510 arranged substantially parallel to the annular mounting plate 112 and a shifting block 520 rotatably arranged on the lock shell 510. The shifting block 520 is eccentrically arranged relative to the axis of the mechanical lock cylinder 500. The shifting block 520 can rotate toward the inside of the rotating sleeve 410 to push the driving member 420 so that the embedding slot 320 is combined with the strip-shaped protrusion. It can be understood that the arrangement direction of the lock shell 510 fully utilizes the radial dimension of the front ball shell 120, and can shorten the length dimension of the front ball shell 120 parallel to the front sleeve 110. When the user inserts the correct key and turns it, the dial block 520 can rotate to swing toward the inside of the rotating sleeve 410, thereby pushing the driving member 420 to move close to the first clutch member 310. The first clutch member 310 and the second clutch member 111 are engaged with each other through the embedded slot 320 and the bar-shaped protrusion. At this time, rotating the front ball lock body 100 can drive the connecting rod 300 to rotate to achieve unlocking.

[0040] See also Figure 5 and Figure 6 In some embodiments of the present invention, in order to realize the rotation of the rotating sleeve 410 and reduce the volume of the driving assembly as much as possible, and to leave more space for the front ball shell 120 to accommodate other parts, the driving assembly includes a driven gear part 430 formed on the outer peripheral edge of the rotating sleeve 410 and located in the accommodating space, a motor 440 provided on the annular mounting plate 112, and a plurality of transmission gears 450 connected between the output shaft of the motor 440 and the driven gear part 430. If the motor 440 rotates clockwise to drive the rotating sleeve 410 to rotate through the transmission gear 450, and then the first clutch 310 and the second clutch 111 are pushed to combine through the driving member 420, the motor 440 rotates counterclockwise to drive the rotating sleeve 410 to reset through the transmission gear 450, the driving member 420 is reset under the action of the elastic member 600, and the first clutch 310 and the second clutch 111 are separated. Of course, in other embodiments, the driving assembly can be replaced by a worm driven to rotate by a motor, and the driven gear portion 430 can be replaced by a worm wheel matched with the worm.

[0041] See also Figure 6 In some embodiments of the present invention, a strip bracket 700 located in the accommodating space is arranged in parallel on the annular mounting plate 112, the motor 440 is mounted on the strip bracket 700 and the output shaft is perpendicular to the annular mounting plate 112, a plurality of transmission gears 450 are rotatably arranged on the strip bracket 700 and mesh with each other, the front end surface of the front ball shell 120 is provided with an identification module 800 electrically connected to the motor 440, and the mechanical lock core 500 is located between the identification module 800 and the rotating sleeve 410. Before installing the strip bracket 700, the plurality of transmission gears 450 can be assembled on the strip bracket 700 accordingly to form a meshing state, and then the transmission gear 450 at the end is meshed with the driven gear part 430, so as to facilitate rapid and accurate assembly. In this embodiment, the strip bracket 700 is provided with a plurality of first axial holes at intervals along the length direction, and the annular mounting plate 112 is also provided with a plurality of second axial holes corresponding to the first axial holes one by one, and each transmission gear 450 is penetrated by a pivot, and the two ends of the pivot are respectively inserted into the first axial hole and the corresponding second axial hole, and both ends of the strip bracket 700 are fixed to the annular mounting plate 112 by bolt assemblies, thereby achieving installation and positioning.

[0042] The identification module 800, the mechanical lock core 500, and the transmission gear 450 are sequentially arranged along the direction of the front sleeve 110 to achieve a compact structure in the length direction of the front ball shell 120, which is conducive to further improving the volume redundancy in the front ball shell 120, reducing the precision requirements for parts, reducing costs, and facilitating the diversity of the ball lock appearance. The identification module 800 can be fingerprint recognition, access card recognition, or password disk, etc. Fingerprint recognition, access card recognition, and password disk are all common structures in the field and will not be further described here.

[0043] See also Figure 5 In some embodiments of the present invention, the side of the rotating sleeve 410 is provided with a first spiral slope 411 arranged circumferentially around its central axis, the driving member 420 is provided with a first guide portion 421 opposite to the first spiral slope 411, and the elastic member 600 drives the first guide portion 421 to abut against the first spiral slope 411. It can be understood that when the first guide portion 421 abuts against the low slope of the first spiral slope 411, the first clutch 310 is separated from the second clutch 111 under the action of the elastic member 600, and as the rotating sleeve 410 rotates, the first guide portion 421 climbs along the first spiral slope 411, and when the high slope of the first spiral slope 411 abuts against the first guide portion 421, the driving member 420 pushes the first clutch 310 to move closer to the second clutch 111 until the long protrusion on the inner wall of the front sleeve 110 enters the embedding slot 320 of the first clutch 310. At this time, the user rotates the front sleeve 110 to drive the connecting rod 300 connected to the first clutch 310 to rotate, and when the connecting rod 300 rotates, it drives the lock tongue assembly to unlock or lock.

[0044] See also Figure 2 , Figure 5 and Figure 7In some embodiments of the present invention, the interior of the connecting rod 300 and the first clutch member 310 is provided with a clearance hole 301 penetrating along the length direction of the connecting rod 300, and a knob member 210 is rotatably provided on the rear ball lock body 200, and the knob member 210 is connected to a rotating rod 220 penetrating the clearance hole 301, and the end of the rotating rod 220 away from the knob member 210 is connected to a driving block 230 located between the driving member 420 and the first clutch member 310, and a rotating pushing mechanism is provided between the driving block 230 and the first clutch member 310, and when the driving block 230 rotates, the rotating pushing mechanism can enable the first clutch member 310 to slide to the embedding slot 320 and remain combined with the strip-shaped protrusion. It should be noted that the yielding hole 301 is for the connecting rod 300 to pass through, and the two ends of the connecting rod 300 are respectively passed through the two ends of the yielding hole 301. The connecting rod 300 can rotate freely relative to the yielding hole 301 without interference. When the user turns the knob member 210, the knob member 210 drives the rotating rod 220 and the driving block 230 to rotate together. The driving block 230 uses the rotating pushing mechanism to drive the first clutch member 310 to move to a state where the embedding slot 320 and the strip-shaped protrusion are kept in combination. At this time, the electric ball lock of the present invention is in a normally open state, and the front ball lock body 100 or the rear ball lock body 200 can be directly rotated to open and close the lock without the electric clutch mechanism 400 and the mechanical lock core 500 working, thereby enriching the use function of the electric ball lock.

[0045] See also Figure 8 and Fig. 9 In some embodiments of the present invention, the rotation pushing mechanism includes a second spiral slope 241 arranged around the central axis of the rotating rod 220 and a second guide portion 242 matching the second spiral slope 241, one of the second spiral slope 241 and the second guide portion 242 is arranged on the first clutch member 310, and the other is arranged on the driving block 230, the upper end of the second spiral slope 241 is connected to a stop plane 243, and the elastic member 600 can drive the second guide portion 242 to abut against the second spiral slope 241 or the stop plane 243. In this embodiment, the second spiral slope 241 is arranged on the side of the first clutch 310 close to the driving block 230, and the second guide portion 242 is arranged on the side of the driving block 230 close to the first clutch 310. When the second guide portion 242 abuts against the low slope of the second spiral slope 241, the first clutch 310 is separated from the second clutch 111 under the action of the elastic member 600. As the knob member 210 drives the rotating rod 220 and the driving block 230 to rotate together, the second guide portion 242 climbs along the second spiral slope 241 until the second guide portion 242 passes over the second spiral slope 241 and abuts against the stop plane 243. The embedded slot 320 and the strip protrusion remain in a combined state, thereby realizing the normally open use mode of the electric ball lock.

[0046] See also Figure 8 and Fig. 9 When the driving block 230 rotates relative to the first clutch 310, the second guide portion 242 moves along the second spiral slope 241. In order to make the second guide portion 242 slide smoothly on the second spiral slope 241, in some embodiments of the present invention, the two second spiral slopes 241 and the two stop planes 243 are both formed on the side of the first clutch 310 facing the driving block 230 and are centrally symmetrical. The second guide portion 242 is formed on the side of the driving block 230 facing the first clutch 310. The second guide portion 242 is provided with a ball 244 that can slide along the second spiral slope 241.
