The first guide portion 703 and the second guide portion 704 may be formed in various ways, for example, the first guide portion 703 and the second guide portion 704 are guide grooves.

The "first cable 500" can be one of the parts of the "connecting device 700", i.e. assembled with the "other members of the connecting device 700" into one module, and then assembled modularly; or may be separate from the other components of the connection device 700, i.e., may be integrated with the other components of the connection device 700.

In this manner, by providing the second connection portion 702, it is facilitated to fix the second cable 600 to the second conductor 721.

Specific implementations of the second connection portion 702 include, but are not limited to, a pad, an electrical connection joint, and the like.

Equivalently, the components included in the electronic door lock 10 of the present disclosure can also be flexibly combined, i.e., can be produced in a modularized manner according to the actual situation, and can be assembled in a modularized manner as an independent module; the modules may be assembled separately, and one module may be constructed in the present apparatus. The division of the above-mentioned components in the present disclosure is only one embodiment, which is convenient for reading and not limiting the scope of protection of the present disclosure, and the technical solutions equivalent to the present disclosure should be understood as if they are included and the functions are the same.

In order to reduce interference or electric leakage, the guide piece and the rotating piece are arranged in an insulating mode. And the insulation between the guiding element and the rotating element includes, but is not limited to, coating an insulating material, or the guiding element is made of an insulating material and/or the rotating element is made of an insulating material, etc.

In addition to any of the above embodiments, as shown in fig. 4 to 6, in an embodiment, the material of the guide 710 is an insulating material, the guide 710 has a first mounting groove 712 for mounting the first conductor 711, and at least a portion of the first conductor 711 is embedded into the guide 710 through the first mounting groove 712. Thus, the guide 710 is made of an insulating material, and then the first conductive body 711 is mounted by using the first mounting groove 712, which facilitates insulation of the first conductive body 711 so that the first conductive body 711 is not easily short-circuited.

And/or, in an embodiment, the rotating member 720 is made of an insulating material, the rotating member 720 is provided with a second mounting groove 722 for mounting the second conductive body 721, and at least a portion of the second conductive body 721 is embedded into the rotating member 720 through the second mounting groove 722. Thus, the rotating member 720 is made of an insulating material, and then the second conductive body 721 is installed by using the second installation slot 722, so that the second conductive body 721 is insulated and protected, and the second conductive body 721 cannot be easily short-circuited.

Each conductor can be fixed in the corresponding mounting groove through a plurality of fixing modes, including but not limited to bonding, screwing, clamping and the like.

Furthermore, it can be understood that, since the rotator 720 itself has an insulating property, more second conductors 721 can be disposed on the rotator 720 to achieve different communication requirements or conduction requirements.

For example, as shown in fig. 6, in some embodiments, at least two second conductive bodies 721 are provided, and two adjacent second conductive bodies 721 are insulated and fixed on the rotating member 720. In this manner, at least two conductive connection points can be formed on the rotating member 720 to facilitate different conductive and/or communication requirements for the connection points of at least two circuits.

Alternatively, two adjacent second conductors 721 are connected to the first conductor 711 through one-to-one corresponding conductive members 730. Thus, at least two circuits can be formed to meet different communication requirements or conduction requirements.

The specific implementation manner of the insulation arrangement between two adjacent second conductive bodies 721 can be various, including but not limited to coating an insulating layer, wrapping an insulating layer or separating with an insulating material, etc.

As shown in fig. 4 and fig. 6, in an exemplary embodiment, the connecting device 700 further includes an insulating sheet 750, and the insulating sheet 750 is disposed between two adjacent second conductive bodies 721 to insulate the two adjacent second conductive bodies 721. Thus, the second conductive bodies 721 can be modularly assembled by using the insulating sheet 750, so that the adjacent two second conductive bodies 721 are arranged in an insulating manner, which is beneficial to improving the assembly efficiency of the connecting device 700.

For example, in combination with the above-described embodiment of the second mounting groove 722, two adjacent second conductors 721 are annular, and the corresponding insulating sheet 750 is also annular and is assembled in the second mounting groove 722.

Alternatively, the first conductors 711 may also be electrically connected to a corresponding second conductor 721 to form at least two circuits, as described above.

For example, the first conductor 711, the second conductor 721 and the conductive member 730 are two and correspond to each other in a group, so that two communication channels are formed, one of the communication channels is used for low frequency communication, and the other communication channel is used for high frequency communication.

Of course, in other embodiments, if only one circuit is needed, the guiding element and the rotating element can be made of conductive materials, the first conductive body is a part of the guiding element, and the second conductive body is a part of the rotating element.

In any of the above embodiments, as shown in fig. 4 and fig. 6, in an embodiment, the conductive member 730 has elasticity and can be elastically clamped between the first conductive body 711 and the second conductive body 721. Thus, the conductive member 730 can be in sufficient contact with the first conductive member 711 and the second conductive member 721, so that the first conductive member 711 and the second conductive member 721 can be reliably electrically connected, and the rotation of the second conductive member 721 is not affected.

Optionally, the conductive member 730 is pressed between the first conductive member 711 and the second conductive member 721, and has a "V" shape. Thus, by compressing the conductive member 730, the conductive member 730 can be fully contacted with the first conductive member 711 and the second conductive member 721, and the contact force is maintained, so that the first conductive member 711 and the second conductive member 721 are electrically connected reliably.

In addition to any of the above embodiments, as shown in fig. 5 and 6, in one embodiment, the guide 710 and the rotating member 720 are annular. Thus, the rotating member 720 can rotate 360 degrees relative to the guiding member, so that the installation positions of the first cable 500 and the second cable 600 can be selected more flexibly, and the installation is more convenient. In addition, the rotation member 720 is formed in a circular ring, and performs an installation operation using an inner space of the circular ring, or receives other structures of the electronic door lock 10, such as a rotation shaft.

Further, the first conductor 711 has an annular shape, and/or the second conductor 721 has an annular shape. Similarly, the second conductive body 721 can rotate 360 ° relative to the first conductive body, so that the installation position of the handle 200 can be selected more flexibly and the installation is more convenient.

In the embodiment, as shown in fig. 4 to 6, the connecting device 700 further includes a bearing 740, and the guide 710 is rotatably connected to the rotating member 720 through the bearing 740. In this way, the guide 710 and the rotor 720 are rotatably connected by the bearing 740, so that the reliability of the connection between the guide and the rotor can be improved, the maintenance is easy, and the smoothness of the rotation between the guide and the rotor can be improved.

In addition, since the guide 710 is rotatably connected to the rotating member 720 through the bearing 740, the connection between the two is more reliable, so that the handle 200 can be rotatably connected through the connecting device 700, which is beneficial to improving the assembly efficiency of the electronic door lock 10.

In an exemplary embodiment, as shown in fig. 4 and 7, two bearings 740 are disposed and spaced between the guide 710 and the rotating member 720 to form a protection space 741, and the first conductor 711, the second conductor 721 and the conductor 730 are disposed in the protection space. In this way, the bearing 740 forms the protective space 741, whereby the first conductor 711, the second conductor 721, and the conductor 730 can be protected in an exchangeable manner, and the reliability can be further improved.

Note that the "first conductor 711" may be a "part of the guide 710", that is, the "first conductor 711" and the "other part of the first conductor 711" may be integrally formed by a conductive material; alternatively, a separate member may be provided that is separable from the rest of the guide 710, i.e., the first conductor 711 may be manufactured separately and then integrated with the rest of the guide 710.

Equivalently, the "body" and the "certain part" can be parts of the corresponding "component", i.e., the "body" and the "certain part" are integrally manufactured with other parts of the "component"; the "part" can be made separately from the "other part" and then combined with the "other part" into a whole. The expressions "a certain part" and "a certain part" in the present disclosure are only one embodiment, and are not intended to limit the scope of the present disclosure for convenience of reading, and should be construed as equivalents of the present disclosure as long as the features are included and the effects are the same.

In addition to any of the above embodiments, as shown in fig. 6, in one embodiment, at least two conductive members 730 are provided and spaced apart along the length direction of the first conductive member 711. Thus, the first conductor 711 and the second conductor 721 are electrically connected by at least two conductive members 730, which not only increases the contact area of the electrical connection, but also improves the reliability, thereby avoiding poor contact caused by abrasion of part of the conductive members 730.

As shown in fig. 5 and 6 in combination with fig. 7, the guide 710 is a member that enables the rotor 720 to rotate in the circumferential direction. The specific structure of the guiding element 710 may be various, including but not limited to a circular guide (as shown in fig. 4), a circular guide (as shown in fig. 7), a circular guide groove, a circular guide tube, an arc-shaped guide rod, etc., and it is sufficient to enable the rotating element 720 to rotate along at least a portion of a circular ring. Correspondingly, the rotation member 720 and the guiding member 710 can be connected in a plurality of ways, such as a direct connection of the guiding rail and the sliding sleeve, a guiding groove and the sliding block, a guiding rod and the sliding sleeve, or a rotation member such as the bearing 740 can be used to realize the rotation of the guiding rail and the sliding sleeve.

The specific structure of the rotating member 720 can also be selected according to the rotation angle required for unlocking the handle 200, including but not limited to a circular-arc sliding sleeve, or a rotating ring.
