[0029] The present application is further described in detail below in conjunction with the accompanying drawings and implementation methods. It is particularly noted that the following implementation methods are only used to illustrate the present application, but do not limit the scope of the present application. Similarly, the following implementation methods are only some implementation methods of the present application rather than all implementation methods. All other implementation methods obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0030] The terms "first", "second" and "third" in this application are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features. Thus, the features defined as "first", "second" and "third" can explicitly or implicitly include at least one of the features. In the description of this application, the meaning of "multiple" is at least two, and the manner is such as two, three, etc., unless otherwise clearly and specifically defined. All directional indications in the implementation mode of this application (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication also changes accordingly. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions.

[0031] Reference to "embodiment" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiment may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0032] For door locks equipped with electronic anti-theft systems, since the operation of opening and closing the door lock must be actively performed by the user, the cover and / or shell of the door lock needs to be provided with openings for passing components such as knobs and touch panels, which inevitably narrows the frame near the opening. The narrow frame has limited space, is weak and easily deformed, and is difficult to fix the frame by opening holes to arrange screws, which requires a large space, so that the cover near the opening cannot be effectively fixed to the shell.

[0033] When the user operates the door lock, the cover body near the door lock is easily deformed, and even causes damage to the door lock. In order to improve or solve the above technical problems, the inventor of the present application has proposed at least the following embodiments after long-term research.

[0034] See also Figure 1 and Figure 2 , Figure 1 It is a schematic diagram of the exploded structure of the driving device fixing structure provided in this application. Figure 2The present invention is a schematic diagram of the assembly structure of the drive device fixing structure provided by the present application. The present application provides a drive device fixing structure for forming a part of the drive device, and the drive device fixing structure may include a main body (1) and a cover body (2). The drive device can be used to dock with the lock cylinder of the door lock (it can be a key inserted in the lock cylinder or a tail rod inserted in the lock cylinder), and can be connected to the lock tongue of the door lock through the lock cylinder, thereby forming an electronic anti-theft system together with the door lock.

[0035] The main body (1) is provided with an installation space (11) inside, and a first opening (12) is provided on the surface of the main body (1) for connecting the outside with the installation space (11). The main body (1) includes a first limiting structure, and the first limiting structure is arranged on the inner wall forming the first opening (12). The cover body (2) is connected to the main body (1) and can at least partially block the first opening (12). The cover body (2) can be provided with a second opening (23), and the first opening (12) and the second opening (23) are connected, so that the structure arranged in the installation space (11) can be connected to the outside through the second opening (23). The cover body (2) includes a second limiting structure and an arc segment (21) close to the second opening (23), and the second limiting structure can be arranged on the arc segment (21).

[0036] The first limiting structure and the second limiting structure can cooperate to fix the arc segment (21) of the main body (1) and the cover body (2), thereby fixing the main body (1) and the cover body (2) in connection.

[0037] Although the screw connection is reliable and can be disassembled, it is necessary to set a structure on the cover body (2) that can pass the screw (3), and the setting of this structure requires a large space to be realized, while the matching connection relationship does not need to occupy too much space on the cover body (2). In the structure provided in this embodiment, the inner wall of the main body (1) forming the first opening (12) is provided with a first limiting structure, and the arc segment (21) of the cover body (2) located near the second opening (23) is provided with a second limiting structure. The first limiting structure and the second limiting structure can be matched and connected, so that the arc segment (21) and the main body (1) are relatively fixed through the cooperation of the two, which can reduce the probability of deformation of the arc segment (21) near the second opening (23), so that the fixed connection relationship between the main body (1) and the cover body (2) is more compact and stable, thereby improving the structural stability of the fixed structure of the drive device.

[0038] Specifically, see Figure 3 , Figure 4 as well as Figure 8 , Figure 3 yes Figure 2 Schematic diagram of the cross-sectional structure of the A-A' section. Figure 4 yes Figure 3 Schematic diagram of the enlarged structure of the D area in the middle. Figure 8 yes Figure 3 Another enlarged structural diagram of the D area in the middle. One of the first limiting structure and the second limiting structure may include a limiting protrusion (24), and the other may include a limiting groove (13), and the limiting protrusion (24) is detachably embedded in the limiting groove (13). Through the simple and reliable embedding relationship between the limiting groove (13) and the limiting protrusion (24), the first limiting structure and the second limiting structure are connected by occupying only a small space in the arc segment (21), thereby improving the stability of the fixed structure of the drive device. In addition, the first limiting structure and the second limiting structure provided in this embodiment are detachably fixed, thereby improving the convenience of maintaining the structure in the installation space (11).

[0039] Optionally, in the direction of the thickness of the cover body (2), the radial dimension of at least part of the limiting protrusion (24) is gradually reduced, so as to form a guide surface (242) on the side of the limiting protrusion (24) facing the installation space (11). The setting of the guide surface (242) can play a guiding role in the process of installing the cover body (2) and the inner wall of the main body (1) to form the first opening (12), so that the limiting protrusion (24) can enter the limiting groove (13) more easily and thus cooperate with the limiting groove (13), thereby improving the efficiency and accuracy of the cooperation between the first limiting structure and the second limiting structure.

[0040] Optionally, the limiting protrusion (24) may further include a first limiting surface (241), and the limiting groove (13) includes a second limiting surface (131), the first limiting surface (241) being arranged on the side of the limiting protrusion (24) facing the outside, and the second limiting surface (131) being arranged on the inner wall of the limiting groove (13) corresponding to the first limiting surface (241). When the cover body (2) is subjected to force in a direction away from the installation space (11), the first limiting surface (241) abuts against the second limiting surface (131), thereby preventing the limiting protrusion (24) from escaping from the limiting groove (13) to a certain extent, so that the first limiting structure and the second limiting structure are mutually limited, thereby fixing the arc segment (21) and the main body (1) relatively.

[0041] like Figure 3 , Figure 4 As shown, the first limiting structure may include a limiting groove (13), the second limiting structure may include a limiting protrusion (24), and the guide surface (242) is arranged on a side surface of the second limiting structure facing the installation space (11). During the process of installing the cover body (2) on the main body (1), the limiting protrusion (24) of the second limiting structure is embedded in the limiting groove (13) of the first limiting structure under the action of the guide surface (242), and the first limiting surface (241) and the second limiting surface (131) are pressed against each other.

[0042] like Figure 8As shown, the first limiting structure may also include a limiting protrusion (24), and the second limiting structure may include a limiting groove (13). In this embodiment, the guide surface (242) may be arranged on the side of the first limiting structure facing the outside. Under the guidance of the guide surface (242), the limiting groove (13) of the second limiting structure can gradually cooperate with the limiting protrusion (24) of the first limiting structure as the cover body (2) moves. The first limiting surface (241) may be arranged on a side surface of the limiting protrusion (24) facing the installation space (11). When the cover body (2) is subjected to force in a direction away from the installation space (11), the second limiting surface (131) abuts against the first limiting surface (241) to limit the cover body (2).

[0043] Furthermore, the portion of the main body (1) corresponding to the arc segment (21) can be arc-shaped, so that the main body (1) surrounds the arc segment (21). The corresponding arc-shaped portion of the main body (1) can better cooperate with the arc segment (21), so as to improve the stability of the connection between the first limiting structure and the second limiting structure, and make the overall design of the fixed structure of the driving device more beautiful and reasonable.

[0044] Optionally, the number of the second limiting structures may also be multiple, and the multiple second limiting structures can be evenly arranged along the arc segment (21), and the number and position of the first limiting structures correspond to the number and position of the second limiting structures. Thus, by utilizing the mechanical particularity of the arc structure, a force is evenly applied along the arc segment (21) to limit the cover body (2), forming a tightening force pointing to the center of the arc where the arc segment (21) is located, reducing the probability of the arc segment (21) warping, loosening, etc. due to uneven force, so that the fixed connection between the cover body (2) and the main body (1) is more reliable.

[0045] Optionally, see Figure 1 The main body (1) and / or the cover body (2) may further include a third limiting structure (14), and the third limiting structure (14) is abutted between the main body (1) and the cover body (2). Even if there is a gap between the inner wall of the main body (1) forming the first opening (12) and the cover body (2), the third limiting structure (14) can also abut in the gap, thereby reducing the probability of the cover body (2) shaking relative to the main body (1) due to the existence of the gap.

[0046] Optionally, the third limiting structure (14) can be specifically arranged on the inner wall of the main body (1) forming the first opening (12), and abut against the arc segment (21) of the cover body (2), thereby improving the stability of the fixed connection between the arc segment (21) of the cover body (2) and the main body (1).

[0047] Optionally, the number of the third limiting structures (14) can be multiple, and the multiple third limiting structures (14) are arranged on the inner wall of the main body (1), and the third limiting structures (14) protrude toward the center of the first opening (12) to abut against the outer peripheral surface of the cover body (2). The multiple third limiting structures (14) apply forces toward the center of the first opening (12) to the cover body (2) in different directions, and can evenly apply forces to the cover body (2), thereby reducing the probability of a certain part of the arc segment (21) being broken or deformed due to the uniform force-bearing part, and improving the limiting effect on the cover body (2).

[0048] Specifically, the third limiting structure (14) can be oriented toward the center of the arc where the arc segment (21) is located, and can be evenly arranged corresponding to the arc segment (21) to apply a centripetal tightening force to the arc segment (21) to enhance the limiting effect on the arc segment (21).

[0049] Optionally, the third limiting structure (14) can be made of soft rubber, and the flexible soft rubber is elastically deformed by the compression of the cover body (2) and the main body (1), so as to facilitate the installation of the cover body (2). At the same time, the soft rubber material can also play a buffering role between the cover body (2) and the main body (1), thereby reducing the probability of damage to the cover body (2) and the main body (1) during the assembly process.

[0050] See also Figure 5 , 6 , Figure 5 yes Figure 2 Schematic diagram of the cross-sectional structure of the C-C' section. Figure 6 yes Figure 5 An enlarged structural diagram of the middle E area. For the embodiment of the fixed structure of the driving device provided in the present application, the main body (1) may further include a fourth limiting structure (15), which is arranged on the inner wall of the main body (1) and is used to limit the cover body (2).

[0051] The fourth limiting structure (15) may specifically include a third limiting surface (151), and the third limiting surface (151) is arranged opposite to a surface of the cover body (2) facing the installation space (11). When the cover body (2) is subjected to a force in a direction close to the installation space (11), the third limiting surface (151) can abut against the surface of the cover body (2), thereby supporting the cover body (2), reducing the probability of the cover body (2) sinking into the installation space (11) under the action of the force, and improving the stability of the relative fixation of the cover body (2) and the main body (1).

[0052] Optionally, the number of the fourth limiting structures (15) can be multiple, and the multiple fourth limiting structures (15) can be arranged on the inner wall of the main body (1) to form the first opening (12), and can evenly apply force to the side surface of the cover body (2) facing the installation space (11).

[0053] See also Figure 2 and Figure 7 , Figure 7 yes Figure 2 The schematic diagram of the cross-sectional structure of the section B-B' in the figure. The drive device fixing structure may further include at least one screw (3), and the cover body (2) may further include a panel (22), and the panel (22) is connected to the arc segment (21). Since the panel (22) has a larger area than the arc segment (21) near the second opening (23), there is enough space to arrange the structure for fixing by means of the screw (3), thereby further improving the reliability of fixing the cover body (2) and the main body (1) by means of simple screw connection.

[0054] Specifically, one of the panel (22) and the main body (1) may include a stud (221), and the other may include at least one through hole (16), the through hole (16) can connect the installation space (11) with the outside, and the through hole (16), the stud (221), and the screw (3) correspond to each other. When the cover (2) and the main body (1) are relatively fixed, the screw (3) can be inserted into the through hole (16) and screwed with the stud (221), so that the panel (22) of the cover (2) and the main body (1) are relatively fixed, thereby improving the stability of the fixed connection between the cover (2) and the main body (1).

[0055] Furthermore, one of the panel (22) and the main body (1) provided with the through hole (16) may further include a docking groove (17), the docking groove (17) being provided on a side surface of the cover body (2) or the panel (22) facing the installation space (11), the through hole (16) being provided at the bottom of the docking groove (17), and the stud (221) being inserted into the docking groove (17). The existence of the docking groove (17) can help the stud (221) to align with the through hole (16), so that the screw (3) passing through the through hole (16) can be more smoothly screwed with the stud (221), thereby improving the efficiency and stability of the fixed connection between the cover body (2) and the main body (1).

[0056] See also Figure 7 The stud (221) can be specifically arranged on a side of the panel (22) facing the installation space (11), the through hole (16) is provided on the main body (1), and the docking groove (17) is arranged on a side surface of the main body (1) facing the installation space (11). The inner diameter of the docking groove (17) can be slightly larger than the outer diameter of the stud (221) to limit the stud (221), and the stud (221) can be docked with the through hole (16) by using the docking groove (17), so that the screw (3) passing through the through hole (16) can be screwed with the stud (221) more accurately.

[0057] The screw (3) may specifically include a head (31) and a screw rod (32); the radial dimension of the through hole (16) is smaller than the radial dimension of the head (31) and larger than the radial dimension of the screw rod (32), so that the screw rod (32) can be inserted into the through hole (16), and the head (31) abuts against a side surface of the main body (1) facing away from the installation space (11), thereby utilizing the screw rod (32) to be screwed with the stud (221), thereby fixing the main body (1) and the panel (22) relatively.

[0058] Specifically, one end of the stud (221) that is threadedly connected to the screw (3) may be provided with a threaded hole (222), a thread matching the screw (3) is provided in the threaded hole (222), and the screw (3) and the thread cooperate to be screwed into the threaded hole (222), thereby achieving relative fixation of the screw rod (32) and the stud (221).

[0059] Furthermore, a thread may be provided in the through hole (16) so that the screw (3) and the main body (1) are more tightly connected.

[0060] Optionally, a guide groove (18) may be provided on a surface of the main body (1) facing the outside, and the through hole (16) is provided at the bottom of the guide groove (18), so as to communicate with the outside through the guide groove (18). The screw (3) may be entirely inserted into the guide groove (18), and the head (31) of the screw (3) abuts against the surface of the bottom of the guide groove (18) formed by the main body (1). The guide groove (18) may hide the head (31) of the screw (3) exposed to the outside, thereby reducing the probability of the head (31) being affected by the outside, causing the screw (3) to become loose or even damaged.

[0061] Optionally, the radial dimension of the guide groove (18) may be slightly larger than the radial dimension of the head (31), and the depth direction of the guide groove (18) may be parallel to the direction in which the screw (3) is screwed into the stud (221). The guide groove (18) can limit the head (31) of the screw (3), which is conducive to accurately docking the screw (3) with the through hole (16), and can also indirectly limit the angle at which the screw (3) is screwed into the stud (221), thereby reducing the probability of damage to the screw (3) or the stud (221) due to an incorrect screwing angle of the screw (3), and improving the stability of the "screw (3)-through hole (16)-stud (221)" fastening system.

[0062] In addition to the screw fastening method, the first limiting structure, the second limiting structure, the third limiting structure (14) and the fourth limiting structure (15) can also be used to limit the panel (22). For example, the second limiting structure is arranged on the side of the panel (22) opposite to the main body (1), so as to cooperate with the first limiting structure arranged on the main body (1) to fix the panel (22) and the main body (1) relative to each other.

[0063] Optionally, a first magnetic component and a second magnetic component may be respectively arranged on the panel (22) and the main body (1), wherein the first magnetic component and the second magnetic component have opposite polarities, thereby utilizing the mutual attraction between the first magnetic component and the second magnetic component to achieve relative fixation of the main body (1) and the panel (22).

[0064] Different from the prior art, the embodiment of the present application further provides a driving device, comprising a knob and a driving device fixing structure as described in any of the above embodiments. The knob is installed in the installation space (11) of the driving device fixing structure, and at least part of the knob is exposed through the second opening (23) of the driving device fixing structure.

[0065] Among them, the knob can be transmission-connected with the lock core of the door lock. When the knob rotates relative to the fixed structure of the driving device, the lock core of the door lock can rotate accordingly, which can drive the lock tongue of the door lock to extend or retract, so that the door lock is opened or closed.

[0066] Optionally, the user can manually twist the portion of the knob exposed through the second opening (23) to extend and retract the locking tongue.

[0067] Optionally, the driving device may further include a motor, the output end of the motor is connected to the knob, and when the user issues an unlock command, the knob can be automatically rotated under the drive of the motor, thereby driving the lock tongue to extend and retract. For example, the user uses the key of the electronic anti-theft system to enter a password.
