Description

Technical Field

[0001] This invention relates to the field of lock technology, and in particular to an electric ball lock. Background Technology

[0002] Ball locks are favored by users because they are easy to hold and allow users to easily turn them to unlock. To achieve intelligent unlocking, existing technology has developed electrically operated ball locks, which include an electric unlocking mechanism, a mechanical lock cylinder, and a battery that powers the electric unlocking mechanism.

[0003] The battery occupies a large space. Since the front ball lock body and the rear ball lock body need to be fastened with long bolts, the rear ball lock body of a typical ball lock generally includes a rear frame, a rotating sleeve rotatably mounted on the rear frame, and a rear ball housing inserted and fixed on the rotating sleeve. During assembly, the rear frame body and the front frame body of the front ball lock body are connected by long bolts, and then the rear ball housing is inserted and fixed on the rotating sleeve. This type of rear ball lock body cannot house the battery inside the rear ball lock body.

[0004] Since the electric unlocking mechanism and mechanical lock cylinder already occupy most of the internal space of the front ball lock body, if the battery is placed inside the front ball lock body, the size of the front ball lock body needs to be increased, which will affect the user's feel.

[0027] Reference Figures 1 to 3 An electric ball lock according to an embodiment of the present invention includes: a front ball lock body 100 and a rear ball lock body 200. The rear ball lock body 200 includes a rear fixed frame 210 and a rear handlebar sleeve 220 rotatably disposed on the rear fixed frame 210. The rear handlebar sleeve 220 has an open cavity 221. The rear handlebar sleeve 220 is detachably fitted with a rear cover 230 for closing the open cavity 221. A receiving space is defined between the rear cover 230 and the rear handlebar sleeve 220. A storage battery 300 is disposed in the receiving space. The rear handlebar sleeve 220 is provided with a wire channel 222 passing through the rear fixed frame 210. The wire channel 222 is used to pass through a wire connected to the storage battery 300.

[0028] The rear handle sleeve 220 of the electric ball lock with the above structure is directly rotatably mounted on the rear fixed frame 210. The cavity 221 of the rear handle sleeve 220 is used to accommodate the battery 300. The rear cover 230 is used to open or close the opening of the cavity 221. The wire channel 222 allows the wires connected to the battery 300 to pass through. The wires can be connected to the electric unlocking structure located in the front ball lock body 100. It should be noted that the wire connecting the electric unlocking structure and the battery 300 has an extendable section. When the rear handle sleeve 220 rotates relative to the rear fixed frame 210, the wire will not be taut. This achieves both the integration of the battery 300 into the rear ball lock body 200 and ensures that the rear ball lock body 200 can rotate normally to achieve the functions of unlocking and locking. Compared with traditional ball locks that use rotating sleeves, this electric ball lock has a simpler structure, requires fewer assembly steps from the user, and does not need to change the shape and size of the front ball lock body 100 and the rear ball lock body 200, thus avoiding affecting the user's feel.

[0029] See Figure 2 and Figure 3 In some embodiments of the present invention, the rear handle sleeve 220 includes a bushing portion 223, and the rear fixed frame 210 is provided with a first through hole 211 for the bushing portion 223 to rotate. A connecting rod 400 capable of rotating with the bushing portion 223 passes through the middle of the bushing portion 223, and the end of the connecting rod 400 away from the bushing portion 223 is connected to the front ball lock body 100. It can be understood that when the user grips and rotates the rear ball lock body 200, the bushing portion 223 rotates relative to the first through hole 211, and at the same time drives the connecting rod 400 and the rear handle sleeve 220 to rotate together, thereby realizing the action of opening or closing the door. The aforementioned rear handle sleeve 220 not only realizes the function of rotating relative to the rear fixed frame 210, but also has the characteristics of compact structure, and does not change the overall size of a typical ball lock.

[0030] Specifically, in this embodiment, the rear handle sleeve 220 further includes an annular shell connected to the bushing portion 223 and a hemispherical shell connected to the annular shell. The bushing portion 223, the annular shell, and the hemispherical shell are an integral structure. The rear cover 230 is generally hemispherical, and the rear cover 230 and the hemispherical shell together form a spherical structure for the user to grip.

[0031] See Figure 2 and Figure 3 In some embodiments of the present invention, the outer peripheral wall of the bushing portion 223 is provided with a radially inwardly recessed groove portion 2231. The groove portion 2231 extends along the length direction of the bushing portion 223 and communicates with the cavity 221. A wire channel 222 is defined between the groove portion 2231 and the inner peripheral wall of the first through hole 211. It can be understood that when the bushing portion 223 rotates, the groove portion 2231 rotates with the bushing portion 223. A wire channel 222 for the power supply line to pass through can always be formed between the groove portion 2231 and the inner peripheral wall of the first through hole 211. Compared with the method of machining the wire channel 222 on the bushing portion 223, the above-structured bushing portion 223 is easier to manufacture and process, and it is more convenient to thread wires through it.

[0032] See Figure 2 and Figure 3 In some embodiments of the present invention, in order to position and fix the battery 300 and prevent the battery 300 from shaking relative to the rear handle sleeve 220, the rear handle sleeve 220 is provided with a battery compartment 500 for accommodating the battery 300. The battery compartment 500 is provided with a first contact member 510 located at the communication point between the groove portion 2231 and the cavity 221, and the rear cover 230 is provided with a second contact member 231 that cooperates with the first contact member 510. It can be understood that the first contact member 510 and the second contact member 231 are respectively connected to the positive and negative terminals of the battery 300. The wire passes through the groove portion 2231 and is connected to the first contact member 510, which facilitates the connection between the battery 300 and the electric unlocking structure.

[0033] See Figure 2 In some embodiments of the present invention, the bushing portion 223 has a second through hole in the middle for the connecting rod 400 to pass through. The second through hole penetrates the bottom of the cavity 221. The battery compartment 500 has a countersunk hole 520 in the middle opposite to the second through hole. One end of the connecting rod 400 away from the front ball lock body 100 extends into the countersunk hole 520. It should be noted that after one end of the connecting rod 400 passes through the second through hole, it enters the countersunk hole 520, making full use of the internal space of the rear handlebar sleeve 220 to accommodate the connecting rod 400. This does not change the traditional relative position between the connecting rod 400 and the rear ball lock body 200, nor does it require changing the length of the connecting rod 400, thus reducing the cost of modifying the production equipment.

[0034] See Figure 2 and Figure 3 In some embodiments of the present invention, the countersunk hole 520 is located in the middle of the battery compartment 500, and the battery compartment 500 has a plurality of cylindrical recesses 530 distributed circumferentially around the center line of the countersunk hole 520. The battery 300 includes a plurality of cylindrical dry cells corresponding one-to-one with the cylindrical recesses 530. It should be noted that the center line of the countersunk hole 520 and the center line of the connecting rod 400 are both located on the geometric center line of the rear handlebar sleeve 220. The arrangement of the plurality of cylindrical recesses 530 and the plurality of cylindrical dry cells is conducive to making full use of the accommodating space, so that the rear handlebar sleeve 220 can accommodate the battery 300 with a larger capacity as much as possible, and it is also conducive to achieving dynamic balance when the rear handlebar sleeve 220 rotates, improving the feel of the user when rotating the ball lock body 200.

[0035] See Figure 3 In some embodiments of the present invention, the outer wall of the battery compartment 500 is provided with a plurality of circumferentially distributed side ears 540. The battery compartment 500 is connected to the rear handlebar sleeve 220 by first fastening screws passing through the side ears 540. It is understood that the battery compartment 500 and the rear handlebar sleeve 220 are manufactured separately and then assembled, which helps to reduce the difficulty of manufacturing and processing. The method of using the first fastening screws to thread the battery compartment 500 into the rear handlebar sleeve 220 facilitates assembly and makes it convenient to use.

[0036] See Figure 2In some embodiments of the present invention, the battery compartment 500 has a threaded channel 550 at one end near the rear cover 230. The rear cover 230 is connected to the threaded channel 550 by a second fastening screw 232. An angle positioning mechanism 600 is provided between the rear cover 230 and the rear handlebar sleeve 220. It should be noted that the battery compartment 500 is fixed inside the rear handlebar sleeve 220, and the rear cover 230 is detachably installed in the threaded channel 550 using the second fastening screw 232, thus achieving detachable installation of the rear cover 230 in the rear handlebar sleeve 220. The angle positioning mechanism 600 can position the relative angular position between the rear cover 230 and the rear handlebar sleeve 220, thereby determining the angular position of the second electrical connector 231 and ensuring that the second electrical connector 231 can maintain an electrical connection with the battery 300. For example, if the battery 300 is composed of multiple cylindrical dry cell batteries, positioning the angular position of the second electrical connector 231 ensures that the second electrical connector 231 conducts electricity to the multiple cylindrical dry cell batteries.

[0037] See Figure 2 and Figure 3 In some embodiments of the present invention, the angle positioning mechanism 600 includes a positioning hole 610 and a positioning pin 620 that cooperates with the positioning hole 610. One of the positioning hole 610 and the positioning pin 620 is located at the open edge of the cavity 221, and the other is located at the rear cover 230. In this embodiment, the positioning pin 620 is located at the open edge of the rear cover 230, and the positioning hole 610 is located at the open edge of the cavity 221. When the positioning pin 620 is inserted into the positioning hole 610, the second contact member 231 can contact the positive or negative terminal of each cylindrical dry cell battery.

[0038] See Figure 1 and Figure 3 In some embodiments of the present invention, the front ball lock body 100 includes a front fixed frame 110 and a front handle sleeve 120 rotatably disposed on the front fixed frame 110. Two threaded sleeves 700, symmetrical about the axis of the connecting rod 400, are arranged between the front fixed frame 110 and the rear fixed frame 210. A third fastening screw 710 connected to the end of the threaded sleeve 700 passes through the rear fixed frame 210. It should be noted that the threaded sleeve 700 is used to pass through the door panel to connect the front fixed frame 110 and the rear fixed frame 210. The arrangement of two threaded sleeves 700 symmetrical about the axis of the connecting rod 400 helps to securely install the front ball lock body 100 and the rear ball lock body 200 onto the door panel. In this embodiment, the rear handlebar sleeve 220 is also provided with a clearance groove 224 for the third fastening screw 710 to feed and move along the length direction of the threaded sleeve 700. Since the rear handlebar sleeve 220 is installed after the rear fixing frame 210 and is not easy to disassemble, the combination of the third fastening screw 710 and the threaded sleeve 700 can solve the problem that traditional long bolts cannot be used for assembly.

[0039] See Figure 2 and Figure 3 In some embodiments of the present invention, the outer peripheral wall of the bushing portion 223 is provided with a nylon washer 800 that can abut against the inner peripheral wall of the first through hole 211. A portion of the wire channel 222 is defined between the nylon washer 800 and the groove portion 2231. The nylon washer 800 reduces the friction between the bushing portion 223 and the first through hole 211, resulting in a quiet operation. Furthermore, the definition of the wire channel 222 between the nylon washer and the groove portion 2231 reduces the possibility of the wire rubbing against the edge of the first through hole 211 and causing the insulation to crack, thus extending the service life of the electric ball lock.

[0040] Of course, the present invention is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of the present invention. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
