[0004] According to the electric ball lock of the utility model embodiment, the front ball lock body includes a front sleeve and a front ball shell connected with one end of the front sleeve; the rear ball lock body; the connecting rod is connected with the rear ball lock body at one end and has a first clutch member located in the front sleeve at the other end; the second clutch member is located in the front sleeve and can be moved relative to the first clutch member to be connected or separated from the first clutch member; the electric clutch mechanism is located in the front ball shell and is used for driving the first clutch member and the second clutch member to slide along the front sleeve to be connected or separated; the mechanical lock cylinder is located in the front ball shell, and the output end of the mechanical lock cylinder can drive the first clutch member to slide along the front sleeve to be connected or separated from the second clutch member.

[0005] According to the electric ball lock of the utility model embodiment, at least the following beneficial effects are obtained:

[0006] The electric ball lock of the above structure uses a front sleeve to set a first clutch member and a second clutch member that cooperate with each other, and an electric clutch mechanism and a mechanical lock core are arranged in the front ball shell. The electric clutch mechanism or the mechanical lock core drives the first clutch member and the second clutch member to slide relative to each other to achieve connection or separation, so that the structure of the electric ball lock is simple, the volume redundancy in the front ball shell is high, the requirements for the precision of parts are low, the cost is reduced, and the problems of precise and fragile parts, difficult processing and difficult installation can be avoided. The complex structure will not cause the appearance of the front ball shell to be bloated, which is conducive to achieving the diversity of the appearance of the ball lock.

[0007] In some embodiments of the present invention, the connecting rod is capable of reciprocatingly sliding along the length of the front sleeve. The second clutch member is a strip-shaped protrusion or a slot formed on the inner circumferential wall of the front sleeve and extending along the length of the front sleeve. The first clutch member is provided with a slot that mates with the strip-shaped protrusion or a strip-shaped protrusion that mates with the slot. The first clutch member is connected to an elastic member that urges the slot away from the strip-shaped protrusion.

The shift block is rotatable toward the interior of the rotating sleeve to push the driving member, thereby engaging the insertion slot with the bar-shaped protrusion. The arrangement of the lock housing fully utilizes the radial dimension of the front spherical housing, thereby shortening the length of the front spherical housing parallel to the front sleeve.

When the user rotates the knob member, the knob member drives the rotating rod and the driving block to rotate together, and the rotating pushing mechanism drives the first clutch member to move to a state where the embedded slot and the bar-shaped protrusion remain engaged, thereby switching the electric ball lock to a normally open state. The lock can be opened or closed by simply rotating the front ball lock body or the rear ball lock body, thereby enriching the functionalities of the electric ball lock.

For example, they may refer to direct connection or indirect connection through an intermediate medium; fixed connection or detachable connection or integral molding; mechanical connection; internal communication between two components or interaction between two components. Those skilled in the art can reasonably determine the specific meanings of these terms in this utility model based on the specific content of the technical solution.

[0033] Reference Figures 1 to 4 The electric ball lock of the utility model embodiment includes: a front ball lock body 100, which includes 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 inside the front sleeve 110; a second clutch member 111, which is provided in the front sleeve 110 and can move relative to the first clutch member 310 and engage with the first clutch member 310. The clutch 310 is connected or separated; the electric clutch mechanism 400 is arranged in the front ball shell 120, and is used to drive the first clutch 310 and the second clutch 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 310 to slide along the front sleeve 110 and connect or separate with the second clutch 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 structure of the electric ball lock is simple, 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 precise and fragile parts, difficult processing and difficult installation can be avoided. The complex structure will not cause the appearance of the front ball shell 120 to be bloated, 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 is capable of reciprocatingly sliding along the length of the front sleeve 110. The second clutch member 111 is a strip-shaped protrusion or a slot 320 formed on the inner circumferential wall of the front sleeve 110 and extending along the length of the front sleeve 110. The first clutch member 310 is provided with a slot 320 that mates with the strip-shaped protrusion or a strip-shaped protrusion that mates with the slot 320. The first clutch member 310 is connected to an elastic member 600 that urges the slot 320 away from the strip-shaped protrusion. In this embodiment, the second clutch member 111 is a strip-shaped protrusion, and accordingly, the first clutch member 310 is provided with two slots 320. The provision of two strip-shaped protrusions and two slots 320 each facilitates improved stability and reliability of the coupling between the first clutch member 310 and the second clutch member 111. When the strip-shaped protrusion is inserted into the 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 the insertion slot 320 away from the bar-shaped protrusion. At this point, when the user grips the front ball housing 120 and rotates it, the front sleeve 110 rotates idly relative to the connecting rod 300. The front ball lock body 100 is unable to rotate the connecting rod 300, preventing unlocking. To unlock, the electric clutch mechanism 400 or the mechanical lock cylinder 500 drives the first clutch member 310 to overcome the action of the elastic member 600, allowing the insertion slot 320 to engage the bar-shaped protrusion. Rotating the front ball housing 120 then rotates the connecting rod 300 and the rear ball lock body 200, unlocking the bolt assembly of the linked connecting rod 300. Furthermore, the second clutch member 111 is formed on the inner circumference of the front sleeve 110, eliminating the need for additional components and 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 slide telescopically.

[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 slide 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 utility model, the electric clutch mechanism 400 includes the rotating sleeve 410 rotatingly arranged at one end of the front sleeve 110 close to the front spherical shell 120 and the driving assembly driving the rotating sleeve 410 to rotate, the driving member 420 is slidingly arranged in the rotating sleeve 410, and the rotating sleeve 410 can drive the driving member 420 to move in the direction of compressing the elastic member 600 to combine the embedded slot 320 with the strip-shaped protrusion when rotating. It should be noted that if the electric clutch mechanism 400 adopts the reciprocating linear motion along the length direction of the front sleeve 110, the length of the front spherical shell 120 needs to be set to a relatively slender size so as to meet the stroke of reciprocating linear motion and installation requirements, which limits the appearance of the front spherical lock body 100 and is not beautiful enough, and the holding feeling is not good either. The electric clutch mechanism 400 with the above structure adopts the rotating sleeve 410 to rotate to drive 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 cylinder 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, thereby facilitating the shortening of the length of the front spherical shell 120, and the internal space of the front spherical shell 120 is more spacious, and the front spherical shell 120 can be designed to be small in size.

[0039] Referring to Figure 3 , Figure 4 and Figure 6 In some embodiments of the utility model, one end of the front sleeve 110 close to the front spherical shell 120 is provided with an annular mounting plate 112, the front spherical shell 120 is assembled on the annular mounting plate 112 by a plurality of bolts to form a containing space in communication with the rotating sleeve 410, and the containing space is used for containing the electric clutch mechanism 400, the mechanical lock cylinder 500, the identification module 800, a control circuit board and the like. The mechanical lock cylinder 500 includes a lock shell 510 substantially parallel to the annular mounting plate 112 and a knob 520 rotatingly arranged on the lock shell 510, and the knob 520 is eccentrically arranged relative to the axis of the mechanical lock cylinder 500. The knob 520 can rotate towards the inside of the rotating sleeve 410 to push the driving member 420 to combine the embedded slot 320 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 spherical shell 120, and the length of the front spherical shell 120 along the length direction of the front sleeve 110 can be shortened. When the user inserts the correct key and rotates, the knob 520 can rotate to swing towards the inside of the rotating sleeve 410, thereby pushing the driving member 420 to move close to the first clutch member 310, and the first clutch member 310 and the second clutch member 111 are engaged through the cooperation of the embedded slot 320 and the strip-shaped protrusion. At this time, rotating the front spherical lock body 100 can drive the connecting rod 300 to rotate to realize unlocking.

[0040] See also Figure 5 and Figure 6 In some embodiments of the present invention, in order to achieve the rotation of the rotating sleeve 410 while minimizing the volume of the drive assembly and leaving more space in the front ball shell 120 for accommodating other components, the drive assembly includes a driven gear portion 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 portion 430. If the motor 440 rotates clockwise to drive the rotating sleeve 410 to rotate via the transmission gears 450, and then the first clutch member 310 and the second clutch member 111 are pushed together via the driving member 420, then the motor 440 rotates counterclockwise to drive the rotating sleeve 410 to reset via the transmission gears 450. The driving member 420 is reset under the action of the elastic member 600, and the first clutch member 310 and the second clutch member 111 are separated. Of course, in other embodiments, the driving assembly may be replaced by a worm driven to rotate by a motor, and the driven gear portion 430 may 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 is disposed parallel to the annular mounting plate 112 and located within the accommodating space. The motor 440 is mounted on the strip bracket 700 with its output shaft perpendicular to the annular mounting plate 112. A plurality of transmission gears 450 are rotatably mounted on the strip bracket 700 and mesh with each other. An identification module 800 electrically connected to the motor 440 is disposed on the front end of the front spherical housing 120. The mechanical lock cylinder 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 accordingly on the strip bracket 700 to form a meshing state, and then the terminal transmission gear 450 can be meshed with the driven gear portion 430, for convenient, quick, and precise assembly. In this embodiment, the strip bracket 700 is provided with a plurality of first axial holes spaced apart along the length direction, and the annular mounting plate 112 is also provided with a plurality of second axial holes corresponding one to one with the first axial holes. Each transmission gear 450 is passed through a pivot, and the two ends of the pivot are respectively inserted into the first axial hole and the corresponding second axial hole. Both ends of the strip bracket 700 are fixed to the annular mounting plate 112 by a bolt assembly, thereby achieving installation and positioning.

[0042] The identification module 800, mechanical lock core 500, and transmission gear 450 are sequentially arranged along the length of the front sleeve 110 to achieve a compact structure. This further improves volumetric redundancy within the front housing 120, reduces component precision requirements, reduces costs, and facilitates a variety of ball lock designs. The identification module 800 can be a fingerprint recognition module, an access card recognition module, or a combination dial module. These are all common structures in the art and are not 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 rest 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 member 310 is separated from the second clutch member 111 under the action of the elastic member 600. As the rotating sleeve 410 rotates, the first guide portion 421 climbs along the first spiral slope 411. 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 member 310 to move closer to the second clutch member 111 until the long protrusion on the inner wall of the front sleeve 110 enters the embedding slot 320 of the first clutch member 310. At this time, the user rotates the front sleeve 110 to drive the connecting rod 300 connected to the first clutch member 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, a through hole 301 is provided inside the connecting rod 300 and the first clutch member 310 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 which passes through the through 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 cause the first clutch member 310 to slide to the embedding slot 320 and remain engaged with the bar-shaped protrusion. It should be noted that the give-way through hole 301 is for the connecting rod 300 to pass through, and the two ends of the connecting rod 300 respectively pass through the two ends of the give-way through hole 301. The connecting rod 300 can rotate freely relative to the give-way through hole 301 without interference. When the user turns the knob part 210, the knob part 210 drives the rotating rod 220 and the driving block 230 to rotate together. The driving block 230 uses the rotation pushing mechanism to drive the first clutch part 310 to move to the state where the embedded slot 320 and the strip-shaped protrusion are kept engaged. At this time, the electric ball lock of the present invention is in a normally open state. 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 Figure 9In 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 cooperating with the second spiral slope 241. One of the second spiral slope 241 and the second guide portion 242 is provided on the first clutch member 310, and the other is provided 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 rest against the second spiral slope 241 or the stop plane 243. In this embodiment, the second spiral slope 241 is provided on the side of the first clutch member 310 close to the driving block 230, and the second guide portion 242 is provided on the side of the driving block 230 close to the first clutch member 310. When the second guide portion 242 abuts against the low slope of the second spiral slope 241, the first clutch member 310 is separated from the second clutch member 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-shaped protrusion remain in a combined state, thereby realizing the normally open usage mode of the electric ball lock.

[0046] See also Figure 8 and Figure 9 When the driving block 230 rotates relative to the first clutch member 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 utility model, the two second spiral slopes 241 and the two stop planes 243 are both formed on the side of the first clutch member 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 member 310. The second guide portion 242 is provided with a ball 244 that can slide along the second spiral slope 241.
