[0029] In the present invention, unless otherwise clearly defined, the words "set", "install", "connect" and the like should be understood in a broad sense, for example, they can be directly connected or indirectly connected through an intermediate medium; they can be fixedly connected or detachably connected or integrally formed; they can be mechanically connected; they can be the internal connection of two elements or the interaction relationship between two elements. 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.

[0030] Reference Figures 1 to 5 A front lock assembly according to an embodiment of the present invention comprises: a fixed seat 100, a front handle sleeve 200 and a front cover 300, wherein the front handle sleeve 200 comprises a shaft sleeve portion 210 rotatably arranged on the fixed seat 100 and a first sleeve 220 connected to the shaft sleeve portion 210, wherein the shaft sleeve portion 210 is provided with a connecting rod 400 having one end extending into the first sleeve 220, and the first sleeve 220 has a first cavity 221 with an opening facing away from the fixed seat 100, and the front cover 300 can move relative to the first sleeve 220 to open or close the opening of the first cavity 221. A columnar accommodating space is defined between the front cover body 300 and the first shell 220, and an electric clutch mechanism 500 and a plurality of dry batteries are arranged in the accommodating space. The length directions of the electric clutch mechanism 500 and the dry batteries are arranged along the length direction of the accommodating space. The electric clutch mechanism 500 and the plurality of dry batteries are arranged at intervals in the axial circumferential direction of the shaft sleeve portion 210. The electric clutch mechanism 500 has a first clutch member 510 which at least partially extends out of the end of the dry battery and can be combined with or separated from one end of the connecting rod 400 extending into the first shell 220.

[0031] The interior of the front lock assembly of the above structure is surrounded by the front cover body 300 and the first shell 220 to form a columnar accommodating space, and the electric clutch mechanism 500 and multiple dry batteries are arranged in the accommodating space at intervals around the shaft sleeve part 210, and the electric clutch mechanism 500 and the dry batteries are extended along the length direction of the accommodating space. The first clutch member 510 partially extends out of the end of the dry battery to be combined with or separated from the connecting rod 400. Through clever spatial layout and structural design, the internal space of the front lock assembly is fully utilized. Under the premise of not increasing the original shape and size, the electric unlocking mechanism and the dry battery are concentrated in the front lock assembly, and the user's feel is avoided. When the front cover body 300 is moved to open the opening of the first cavity 221, the dry battery can be pulled out for convenient replacement. In comparison, the shell part of the traditional front lock assembly is an integrated structure, which is not conducive to disassembly to replace the soft-pack battery, and the soft-pack battery is usually fixed in the circuit by soldering. There is great difficulty in replacing the soft-pack battery. Therefore, the front lock assembly of the embodiment of the present invention solves the problem that the traditional soft-pack battery has a short life and affects the service life of the electric ball lock.

[0032] It is understandable that when the electric clutch mechanism 500 receives an instruction to drive the first clutch member 510 to engage with the connecting rod 400, the front handle sleeve 200 can drive the connecting rod 400 to rotate by rotating the shaft sleeve portion 210 relative to the fixing seat 100, so that the connecting rod 400 drives the lock tongue assembly to unlock, and the front lock assembly can be normally rotated to open and close the lock while multiple dry batteries are built into the front lock assembly, and it is also convenient to install and replace dry batteries. In addition, since the dry batteries and the electric clutch mechanism 500 are both arranged in the front lock assembly, the problem of the difficulty in connecting and installing the wires between the battery and the electric clutch mechanism 500 due to the battery being arranged in the rear ball lock body is overcome, and there is no problem of wire twisting when rotating the front lock assembly or the rear lock assembly, ensuring the stability of conductive conduction.

[0033] See also Figure 2 , Figure 3 , Figure 5In some embodiments of the present invention, a battery compartment 700 is installed in the accommodation space. The battery compartment 700 is provided with four battery channels 710 for accommodating dry batteries and a mounting position for accommodating the electric clutch mechanism 500 in the axial circumferential direction around the shaft sleeve portion 210. The first clutch member 510 is a latch member that reciprocates in parallel with the axial direction of the shaft sleeve portion 210 and faces the mounting position. The end of the connecting rod 400 extending into the first housing 220 is provided with a coupling member 410. The coupling member 410 is provided with a plug hole 411 that matches the latch member. When the electric clutch mechanism 500 drives the latch member to extend, it can enter the plug hole 411 to unlock. When the latch member is retracted, it leaves the plug hole 411 to lock. It can be understood that each dry battery is inserted into the corresponding battery channel 710 to ensure the stability of the position of the dry battery, thereby ensuring that the electric clutch mechanism 500 can be stably powered. Among them, the overall length dimension range of the electric clutch mechanism 500 located at the installation position has a large amount of overlap with the length dimension range of the dry battery, that is, the electric clutch mechanism 500 only has the pin part extending out of the end of the dry battery, which will not cause the length dimension of the front lock assembly to increase, and maintain the user's usage experience to a certain extent, maintaining a good grip.

[0034] See also Figures 2 to 4 In some embodiments of the present invention, the electric clutch mechanism 500 includes a motor 520 fixed at the installation position, the latch member is provided with a limiting groove 511 extending parallel to the shaft sleeve portion 210, the output shaft of the motor 520 is movably penetrated through the limiting groove 511, the output shaft of the motor 520 is penetrated with a spring member 530 located in the limiting groove 511, the two ends of the spring member 530 respectively abut against the inner walls on the opposite sides of the length direction of the limiting groove 511, the output shaft of the motor 520 is provided with a transmission pin 521 located between two adjacent turns of the spring member 530, and when the motor 520 rotates forward and reversely, the latch member is driven by the spring member 530 to telescope toward the plug hole 411. Specifically, when the motor 520 drives the transmission pin 521 to rotate, the spring member 530 will move axially along the output shaft of the motor 520, the number of turns of the spring spiral coil located on one side of the transmission pin 521 will increase, and the latch member will move in the direction where the number of turns of the spring spiral coil increases, thereby realizing the movement of the latch member inserting into the plug hole 411 or retracting from the plug hole 411. It is easy to understand that the motion mechanism composed of the output shaft of the motor 520, the transmission pin 521 and the spring member 530 is equivalent to a screw nut mechanism. During the rotation of the output shaft of the motor 520, the transmission pin 521 is always located between two turns of the spring spiral coil of the spring member 530.

[0035] As a preferred embodiment of the present invention, the coupling 410 is located at the connection between the shaft sleeve portion 210 and the first shell 220 to avoid occupying more space in the length direction of the front handlebar glove tube 200. The limiting groove 511 and the motor 520 are both located within the length range of the battery compartment 700. A portion of the latch member extends out of the end surface of the battery compartment 700 to cooperate with the coupling 410. The portion of the latch member extending out of the end surface of the battery compartment 700 is located at the periphery of the coupling 410, which will not further increase the space occupied in the length direction of the front handlebar glove tube 200, so that most of the position in the length direction of the front handlebar glove tube 200 is reserved for the battery compartment 700, which is conducive to making the structure of the front lock ball in the length direction more compact.

[0036] See also Figures 2 to 5 In some embodiments of the present invention, in order to enrich the unlocking methods and avoid the problem that the electric clutch mechanism 500 fails and cannot be unlocked, a mechanical lock core 800 is installed in the middle of the battery compartment 700. In order to make full use of the space of the battery compartment 700 for reasonable use, four battery channels 710 and the electric clutch mechanism 500 are arranged around the mechanical lock core 800. The keyhole of the mechanical lock core 800 is exposed at one end of the battery compartment 700 close to the front cover body 300. The side of the latch member is provided with a side push portion 512 opposite to the output end of the mechanical lock core 800. The output end of the mechanical lock core 800 can extend from the other end of the battery compartment 700 to push the side push portion 512 to move so that the latch member is inserted into the plug hole 411. It can be understood that when the front cover body 300 moves relative to the front handle glove sleeve 200 to open the opening of the first cavity 221, the keyhole of the mechanical lock core 800 is exposed, and the user can insert the key into the keyhole and rotate the mechanical lock core 800. The output end of the mechanical lock core 800 can extend toward the direction of the coupling member 410 to push the side push portion 512 to move, thereby driving the latch member to be inserted into the plug hole 411, and then when the front lock assembly rotates, it can drive the connecting rod 400 to rotate together to achieve unlocking.

[0037] See also Figure 3 and Figure 5In some embodiments of the present invention, the installation position includes a long bottom plate 720 formed on the battery compartment 700 and two arc-shaped clamping plates 730 formed on opposite sides of the long bottom plate 720. A mounting groove for preventing the motor 520 from rotating relative to the battery compartment 700 is defined between the long bottom plate 720 and the two arc-shaped clamping plates 730. The latch member has a slider portion slidably arranged in the mounting groove, and the limit groove 511 is formed in the slider portion. The long bottom plate 720 is provided with a clearance opening 721 for the side push portion 512 to extend toward the mechanical lock cylinder 800. Specifically, the battery compartment 700 directly forms the battery channel 710, the long bottom plate 720 and the arc-shaped clamping plates 730 by integral injection molding. The extension directions of the battery channel 710, the long bottom plate 720 and the arc-shaped clamping plates 730 are consistent, so that the structure of the injection mold is simple and the cost is low, which is also conducive to the production and manufacturing of the battery compartment 700. Among them, the installation groove surrounded by the long bottom plate 720 and the two arc-shaped clamping plates 730 constitutes the above-mentioned installation position. The installation groove is used to accommodate the motor 520 and to allow the slider to slide back and forth to combine or separate the latch member and the coupling member 410, achieving the effect of one thing serving two purposes.

[0038] See also Figure 2 and Figure 3 In some embodiments of the present invention, the battery compartment 700 is provided with a first power board 610 abutting against one end of the dry cell at one end close to the fixing seat 100, and the other end of the dry cell extends out of the battery compartment 700 to enter the front cover 300. The front cover 300 is provided with a second power board 620 abutting against one end of the dry cell away from the fixing seat 100. The first power board 610 and the second power board 620 are used to contact the positive and negative electrodes of the dry cell respectively, so that a plurality of dry cells can be connected. It can be understood that most of the dry cell along its length direction is located in the battery compartment 700, and a small part of the dry cell along its length direction is located in the front cover 300, which makes full use of the accommodation space and avoids unnecessary increase in the length dimension of the front lock assembly.

[0039] See also Figure 3 and Figure 5In some embodiments of the present invention, the side edge of the front cover 300 is provided with a shaft portion 321 parallel to the shaft sleeve portion 210, and the first housing 220 or the battery compartment 700 is provided with a shaft hole portion 741 matching the shaft portion 321. The shaft portion 321 can move away from the battery compartment 700 along the shaft hole portion 741 to make the second power board 620 away from the dry battery, and the shaft portion 321 can rotate relative to the shaft hole portion 741 to make the front cover 300 and the second power board 620 rotate relative to the first housing 220 to open the opening of the first cavity 221. It can be understood that when the dry battery needs to be replaced, since a part of the dry battery extends into the front cover 300, the shaft portion 321 directly drives the shaft portion 321 to rotate relative to the shaft hole portion 741, which will collide with the dry battery, and the opening of the first cavity 221 cannot be completely opened, and the second power board 620 will also rub against the positive or negative electrode of the dry battery. When the front lock assembly of the above structure is adopted, the shaft portion 321 can move along the shaft hole portion 741 away from the battery compartment 700 until there is a certain gap between the front cover body 300 and the end of the dry battery. At this time, the front cover body 300 can be rotated to fully open the opening of the first cavity 221. On the premise that the length of the front lock assembly is compatible with the length of the dry battery, convenient replacement of the dry battery can also be achieved.

[0040] See also Figures 1 to 3In some embodiments of the present invention, the first housing 220 includes a cylindrical housing 222 and a first arc housing 223 formed at one end of the cylindrical housing 222, the shaft sleeve portion 210 is formed at the other end of the cylindrical housing 222, the radial dimension of the first arc housing 223 is greater than the radial dimension of the cylindrical housing 222, the front cover 300 includes a second arc housing 310 that can be spliced ​​with the first arc housing 223 to form a spherical surface, the outer peripheral wall of the battery compartment 700 abuts against the inner peripheral wall of the cylindrical housing 222, and the battery compartment 700 is close to the front cover 3 00 is provided with a first end plate 740 protruding radially outward on the end surface, the shaft hole portion 741 is provided at the outer peripheral edge of the first end plate 740, the second arc sleeve 310 is provided with a second end plate 320 facing the opening edge of the first arc sleeve 223, the shaft portion 321 is provided at the outer peripheral edge of the second end plate 320, a second cavity is defined between the second end plate 320 and the second arc sleeve 310, the second power board 620 is located in the second cavity, and the second end plate 320 is provided with a through hole 322 for the dry cell to pass through and abut against the second power board 620. It can be understood that the first arc sleeve 223 and the second arc sleeve 310 are spliced ​​into a spherical segment-shaped surface, and the hand feeling of the user when holding the front lock assembly is completely consistent with that of the ordinary front ball lock body, which is conducive to maintaining a better experience. Since the dry cell is cylindrical, there is an annular internal space between the first arc sleeve 223 and the second arc sleeve 310 and the battery compartment 700, and the annular internal space can accommodate the first end plate 740, the second end plate 320, the rotating shaft portion 321 and the shaft hole portion 741, which perfectly utilizes the internal space of the front lock assembly. In addition, the through hole 322 of the second power board 620 also supports the dry cell, which helps to align the second power board 620.

[0041] See also Figure 1 and Figure 2 In this embodiment, a fingerprint recognition module connected to the electric clutch mechanism 500 is also provided in the second cavity, and the input end of the fingerprint recognition module is exposed on the front end surface of the second arc sleeve 310, so as to facilitate the user to input fingerprint information.

[0042] See also Figure 2 and Figure 4In some embodiments of the present invention, the connecting rod 400 is provided with a through hole portion along its length direction, and the through hole portion is provided with a lever 420 that can rotate relative to the connecting rod 400. One end of the lever 420 extends from the connecting rod 400 and extends to the rear ball lock body. The other end of the lever 420 is provided with a lever block 430 that extends into the first housing 220. At least two contact switches 611 are distributed around the rod direction of the connecting rod 400 on the first power board 610. The electric clutch mechanism 500 has a one-to-one corresponding working mode with the contact switch 611. The contact switch 611 and the electric clutch mechanism 500 are both connected to the control module. The lever block 430 rotates with the lever 420 to trigger one of the contact switches 611 and switch the electric clutch mechanism 500 to a certain working mode. Among them, the lever 420 has a knob at one end extending to the rear ball lock body. When the user grasps the knob and rotates it, the lever block 430 is driven to trigger one of the contact switches 611, thereby switching to the working mode corresponding to the contact switch 611. The specific working mode is set according to actual needs. For example, when a user in a room wants to avoid being disturbed by other people outside the designated group, other people outside the designated group cannot start the electric clutch mechanism 500 even if they enter ordinary identity verification information. However, entering the identity verification information of the designated group can start the electric clutch mechanism 500 to unlock the door. For another example, when a single or multiple users enter the room and perform related private behaviors, in order to obtain a more private use function, the dial block 430 can be turned to trigger another contact switch 611. At this time, the electric clutch mechanism 500 fails, and the person outside the door can only use the key to open the mechanical lock core 800 to unlock the door, which not only has a better privacy protection effect, but also retains the function of being able to unlock the door to ensure safety.

[0043] The present invention also discloses an electric ball lock, comprising a front lock assembly of any of the above technical solutions. The electric ball lock makes full use of the internal space of the front lock assembly through clever spatial layout and structural design, realizes the concentration of the electric unlocking mechanism and dry batteries in the front lock assembly, and does not change the original shape and size of the front lock assembly to avoid affecting the user's use feel; the dry battery is also very convenient to replace, solving the problem that the traditional soft pack battery has a short life and affects the service life of the electric ball lock.

[0044] The technical features of the above embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
