Abstract
Description
[0001] The present utility model provides a drive device (especially a drive device for controlling a lock equipped with a cylinder insert), a rotating housing of the drive device, and a toothed ring of the drive device. The drive device is especially used for controlling a lock equipped with a cylinder insert to achieve the function of entering a protected area. The drive device is installed from the inside of the room and from the protected side. In particular, the solution relates to so-called "smart locks" that can be opened or closed without the authorized person directly contacting the lock.
[0002] In the construction of a drive device for a lock (a smart device of the so-called smart lock type), advantageous features that can be achieved to some extent in the prior art are sought. Such advantageous features include the possibility of the drive device cooperating with a lock provided with a conventional, commonly used cylinder insert having a standardized cross-sectional profile and that can be opened with a key on both sides without the need to modify such a cylinder insert to provide the lock with a drive device.
[0003] Solutions known from the prior art for using a drive device for a conventional cylinder insert with an original key involve solutions for a drive device mounted to a door leaf via a special attachment, where the special attachment is first mounted to the door leaf or the cylinder insert and then to the attachment to which the drive device is mounted. Such a solution is known, for example, from patent specification DE 102004021704 B3, where the drive device has the form of a fixed housing having a knob provided on the housing for manually controlling the lock.
[0004] Of course, in order to transfer the driving force from the drive device to the cylinder insert, only a part of the key can also be used (most commonly a key from which the so-called head has been cut off to reduce the size of the key protruding from the cylinder insert), but this solution is less preferred because it requires the user to cut the key to the appropriate length and this is cumbersome, and additionally, one of the cut keys is not suitable for normal operation.
[0005] However, cutting off the head of the key can obtain another preferred feature, namely a reduction in the size of the drive device for the lock, and this is desired by the user. A drive device with a smaller size looks more aesthetically pleasing, does not change the appearance of the door end, enables the drive device to be used for a door that opens to the outside of the protected room, and the small size of the device reduces the risk of the body of the device contacting the door frame when the door is opened. The small size of the device can also reduce its manufacturing cost and thus its price.
[0006] Another desirable advantage of the drive for the lock is that the lock can be manually opened and closed from the side of the drive, omitting the drive arrangement. This was achieved in the prior art by positioning a knob for manually controlling the lock on the body of the drive.
[0007] Another method known in the prior art, which aims to reduce the size of the drive and at the same time facilitate manual control of the lock, is to use a drive in the form of a rotating housing and attach it to a dedicated cylindrical insert rotary control element formed as a shaft. This solution is known from Polish patent application P.421767. However, this solution has a drawback in that it requires replacing the existing cylindrical lock in the lock with a special cylindrical lock having a conventional external profile that mates with a conventional lock but is equipped with a suitable shaft that mates with a specific type of drive.
[0008] A drive is known from the specification of Polish patent application P.434970, which is intended in particular for opening and closing a lock, for example having a cylindrical insert, to perform the function of accessing a protected area. The drive includes a drive assembly arranged in a rotating housing, and the drive assembly includes at least a drive motor and a toothed wheel transmission, the end gear of which interacts with a toothed ring rotatably and coaxially attached to the housing. The drive is intended to be placed on a special rotary control element arranged in the body of the cylindrical insert. The toothed ring has at least two projections on the side of its face on the outer side relative to the housing of the drive to which it is attached, and the projections are positioned relative to the non-circular body of the cylindrical insert when the device is attached to the cylindrical insert control element such that the line connecting the two projections crosses the area of the cylindrical insert body in cross-section. In this solution, it is not possible to operate the drive using a conventional cylindrical insert and the original key inserted into the lock cylinder insert from the outside. It is necessary to use a special cylindrical insert with a shaft of a specific shape.
[0009] In an attempt to reduce the size of the drive for the lock, manufacturers have also been looking for the best solutions for the construction and position within the drive of the main sub-assemblies that mainly determine the final size of the drive. Such main sub-assemblies include the electrical energy source and the gear transmission. [[ID=X]] [[ID=Y]]
[0010] A large and high-capacity electrical energy source (for example, consisting of several primary or secondary batteries) ensures long operation of the drive between successive battery replacements or battery recharges (and this is advantageous), but using a large electrical energy source increases the size of the drive. Such a solution is disclosed in European application EP 2762661 A1, where four cylindrical batteries are used in the fixed housing of the drive, outside the area of the rotary element that transmits the driving force to the cylindrical insert.
[0011] Another advantageous feature of the drive for the lock is to obtain a suitably large torque which enables a lock with a larger number of locking points to be controlled and thus a greater operating resistance to be controlled. Obtaining a suitably large torque requires the use of a suitably efficient and thus large electric motor, and this involves disadvantageously increasing the size of the drive.
[0012] This is why, in the construction of smart lock type solutions, regardless of the technology used for manufacturing the battery, it is desirable to develop a construction solution for the drive which, while maintaining a simple construction of the drive, allows a favorable ratio to be obtained between the volume of the electrical energy source and the volume of the entire drive, and at the same time allows the small size of the device to be maintained despite the use of a suitably large electric motor.
[0013] In the prior art, the solutions of Polish Patent Applications P.421765 and P.421766 are known, in which it is proposed to use a special battery having a recess or opening in which the electric motor of the drive is arranged. This solution is very effective and enables a significant reduction in the size of the entire drive while maintaining a correspondingly large volume and thus a high capacity of the current source. However, a disadvantage of this solution is that it requires the use of an unconventional battery with a special construction, and this is not cost-effective. It is more cost-effective to use typical cylindrical primary or secondary batteries which are of a type conventionally manufactured. It is also economically preferable to use conventionally manufactured secondary batteries having a shape similar to a rectangular prism, i.e. so-called "pouch" type cells.
[0014] A drive is known from the specification of Polish Patent Application P.434970 which is intended in particular for opening and closing a lock having, for example, a cylinder insert to perform the function of access to a protected area. The drive comprises a drive assembly arranged in a rotating housing, and the drive assembly includes at least a drive motor and a gear transmission, the end gear of which interacts with a toothed ring rotatably and coaxially attached to the housing. The drive is intended to be placed on a special rotary control element arranged in the body of the cylinder insert. The toothed ring has at least two protrusions on the face side of its outer side relative to the housing of the drive to which it is attached, the protrusions being positioned relative to the non-circular body of the cylinder insert when the device is attached to the cylinder insert control element such that the line connecting the two protrusions crosses the area of the cylinder insert body in cross-section. In this solution, it is not possible to operate the drive using a conventional cylinder insert and an original key inserted into the lock cylinder insert from the outside. It is necessary to use a special cylinder insert with a shaft of a specific shape.
[0015] The object of the present invention is to eliminate the above-mentioned drawbacks of the existing solutions and to provide a new solution for the drive device, enabling it to be mounted on an existing conventional cylinder insert without the need to modify it, and the device will be able to interact with a complete key from the side where the device is mounted on the cylinder insert without the need to cut the key, while obtaining a small size of the drive device in a rotatable housing in a form convenient for manual control. At the same time, the application method of the positioning of the main sub-components (such as the electrical energy source, the electric motor, and the gear transmission) that have the most relevant influence on the final size of the drive device provides a minimized size of the drive device, while maintaining a favorable ratio between the volume of the battery and the volume of the entire drive device despite the use of commonly available cylindrical or cuboid batteries. At the same time, the solution according to the present invention also enables the use of an effective and thus relatively large electric motor while maintaining the small size of the drive device. As a result, the drive device according to the present invention has a simple and compact construction and is superior to the devices of the prior art in terms of the required features.

The recess is symmetric with respect to the rotation axis of the rotary housing 3, and the recess has the form of a second elongated groove 12 in its cross-section (shown in Figure 5 and Figure 8 ). The second elongated groove 12 has a substantially elongated rectangular shape, and the longitudinal axis of the elongated rectangle extends through the rotation axis of the rotary housing 3. At the same time, the length of the second groove 12 in the rotary housing 3 is not less than the width A of the head 151 of the key 15 for the cylindrical insert 2, and the width of the second groove 12 in the rotary housing 2 is not less than the thickness of the head 151 of the key 15 for the cylindrical insert 2. Such length and width of the second width 12 determine the possibility of inserting the head 151 of the key 15 into the key recess 11. The depth of the key recess 11 is significantly greater than the length of the head 151 of the key 15 protruding from the cylindrical insert 2 and the shoulder 152.
[0069] To ensure the silent operation of the drive device 1, preferably, the width of the second groove 12 is only slightly greater than the thickness of the head 151 of the key 15 to limit the free rotational movement of the housing 3 relative to the head 151 of the key 15 at the start of the operation of the drive device 1.
[0070] As Figure 3 、 Figure 4 and Figure 5 shown in the first embodiment of the first utility model, the plane including the rotation axis of the rotary housing 3 and the longitudinal axis of the second groove 12 perpendicular thereto divides the rotary housing 3 into two parts. Among them, in one part on one side of the plane that divides the housing into two parts of the rotary housing 3, a drive motor 32 and a gear transmission 33 are positioned (as Figure 4 and Figure 5 shown). In the other part on the other side of the plane that divides the rotary housing into two parts of the rotary housing 3, two cylindrical batteries 34 are arranged, as shown in the views shown in Figure 3 and Figure 5 .
[0071] As Figure 6 、 Figure 7 and Figure 8 shown in the second embodiment of the first utility model, the plane including the rotation axis of the rotary housing 3 and the longitudinal axis of the second groove 12 perpendicular thereto divides the rotary housing 3 into two parts. Among them, in one part on one side of the plane that divides the housing into two parts of the rotary housing 3, a drive motor 32 and a gear 33 are arranged (as Figure 7 and Figure 8As shown). In another part of the rotary housing 3 on the other side of the plane that divides the rotary housing into two parts, a battery 34 shaped like a rectangular prism is arranged, as Figure 6 , Figure 7 and Figure 8 shown in the views.
[0072] Of course, the elements of the drive assembly can be arranged differently, where the drive motor 32, the gear transmission 33, and the battery 34 are located on both sides of the key recess 11 in the rotary housing 3. However, it is important to provide points in the drive motor 32 on one side of the key recess 11 (where the gear transmission is also located) and points in any battery 34 on the other side of the key recess 11 such that the line segment connecting the points on the drive motor 32 and the points on the battery 34 passes through the key recess 11.
[0073] As Figure 3 , Figure 4 and Figure 5 shown in the first embodiment of the first utility model in Figure 6 , Figure 7 and Figure 8 shown in the second embodiment of the first utility model in
[0074] In each of these embodiments of the present utility model, there are a number of points in any cylindrical battery 34 in the first embodiment of the first utility model and in the battery 34 shaped like a rectangular prism in the second embodiment of the first utility model such that the connections of these points to many other points (which can be isolated) in the drive motor 32 form line segments (in the geometric sense) passing through the key recess 11 in the rotary housing 3, and this means that these elements are located on opposite sides of the key recess 11 in the rotary housing 3.
[0074] It is also obvious that to meet this condition, it is sufficient to arrange one battery 34 on the other side of the key recess 11 relative to the positions of the drive motor 32 and the gear transmission 33.
[0075] The key recess 11 defined in the rotary housing 3 together with the key 15 inserted into the cylinder lock 2 and the head 151 of the key 15 located within the key recess 11 constitutes a device for transmitting driving force to the control element 8. The width of the second groove 12 and thus the width of the key recess 11 in the rotary housing 3 relative to the thickness of the head 151 of the key 15 are such that during the operation of the drive device 1, when the rotary housing 3 rotates relative to the cylinder insert 2 of the lock on the immovably arranged toothed ring 5, the rotary housing 3 pulls the head 151 of the key 15 and rotates the key 15 in the control element 8 of the cylinder insert 2.
[0076] As Figure 1 , Figure 2 ,Figure 4 , Figure 5 , Figure 7 and Figure 8 As shown in the embodiment of the first utility model in Figure 7 and Figure 8 , the drive device 1 is provided with a removable housing 301 in the form of a sleeve 302. The sleeve has a bottom 303 and is slidably arranged on the rotary housing 3 and is attached to the rotary housing via a radial snap 304. When the housing 301 is removed, the battery 34 can be accessed for replacement or recharging purposes. The housing 301 is provided with a bottom 303 in the form of an elastic membrane, and the compliance of the elastic membrane enables the microswitch 305 positioned on the surface of the rotary housing 3 below the bottom 303 of the housing 301 (as shown in Figure 2 ) to be pressed. The microswitch 305 is located on the panel 40 constituting the electronic unit for controlling the drive device 1.
[0077] Of course, in other embodiments, the drive device may be provided with a housing 301 and a USB socket opening. The housing 301 has a rigid bottom 303 in which a slidable button capable of pressing the microswitch is arranged, and the USB socket opening is used to charge the secondary battery 34 constituting the electrical energy source.
[0078] As Figure 2 shown, a pressure pad 13 is positioned in the rotary housing 3 along its longitudinal axis and above the head 151 of the key 15. The pressure pad 13 is pressed against the key 15 by a spring, and the spring abuts an internal element of the rotary housing 3 on the other side. The pressure pad is movable along the longitudinal axis of the rotary housing 3, and the function of the pressure pad is to eliminate any possible play in the decoding arrangement of the cylinder insert 2.
[0079] In Figure 1 and Figure 2 shown in the embodiment of the second utility model, the lock includes, for example, a conventionally shaped cylinder insert 2 in a mortise lock installed in a door leaf. The cylinder lock 2 of the lock capable of realizing the function of entering the protected area has a body 6, and the control element 8 of the cylinder insert 2 is rotatably arranged in the body 6. The control element 8 of the cylinder insert 2 can rotate within the body 6 of the cylinder insert 2, but the control element 8 cannot move relative to the body 6 along the longitudinal axis of the body 6 of the cylinder insert 2. As Figure 1 and Figure 2 shown, the body 6 of the cylinder insert 2 has a cylindrical portion 61, and the control element 8 of the cylinder insert 2 is arranged in the cylindrical portion 61. A coding element of the cylinder insert 2 is also arranged within the body 6 and the control element 8 of the cylinder insert 2, and the coding element cooperates with the key 15 inserted into the cylinder insert 2. The key 15 is provided with a head 151 for being grasped when the key 15 is rotated within the cylinder lock 2 when opening the lock. As Figure 18As shown, the key also has a serrated portion 153 that is inserted into the control element of the cylinder insert 2 to decode the interlock in the cylinder insert 2, and a shoulder 152 that connects the serrated portion 153 and the head 151. The head 151 of the key 15 has a thickness defined as the distance between the flat sides of the head 151, and a width defined as the distance between the outermost point of the head 151 of the key 15 between the outer end of the head 151 and the shoulder 152 of the key 15, as Figure 18 (dimension A) shows.
[0080] The head 151 of the key 15 for gripping the key 15 has a width A that is much larger than the shoulder 152 of the key 15. During the process of opening the lock with the key 15, an appropriate torque needs to be applied, and this torque must be transmitted by the person opening the lock to the lock element. The key for the cylinder lock is configured such that the shoulder 152 of the key 15 is narrower than the diameter of the cylindrical portion 61 of the body 6 of the cylinder insert 2 to prevent the shoulder 152 of the key 15 from interfering with the opening of the cylinder insert 2 when shielding the cylinder insert 2. Therefore, the width of the head 151 of the key 15 is also much larger than the diameter of the cylindrical portion 61f of the body 6 of the lock cylinder insert 2.
[0081] As Figure 1 、 Figure 2 shown, in the embodiment of the second utility model, the drive device 1, particularly for closing and opening the cylinder insert 2 of the lock, the drive device 1 includes a rotating housing 3, and the drive assembly is positioned in the rotating housing 3. In Figure 9 、 Figure 10 and Figure 11 shown in the embodiment of the present utility model, the drive assembly includes a battery 34 having a cylindrical shape, a drive motor 32, and a gear transmission 33 having an end gear 4 (as Figure 1 shown), wherein the gear 4, which is the end element of the gear transmission of the drive assembly, cooperates with a toothed ring 5 having internal teeth 9 (as Figure 2 、 Figure 14 、 Figure 15 、 Figure 16 and Figure 17 shown), such that when rotating during the operation of the drive motor 32, the end gear 4 rolls on the internal teeth 9 of the toothed ring 5. As Figure 9 、 Figure 10 and Figure 11 shown, the electrical energy source consists of cylindrical batteries, and these batteries can be primary batteries and secondary batteries.
[0082] As Figure 2As shown, the toothed ring 5 is fixedly and immovably attached to the body 6 of the cylindrical insert 2, and the rotary housing 3 is rotatably and axially immovably mounted in a bearing on the toothed ring 5, wherein the rotary housing 3 includes means for transmitting a driving force to a control element 8 of the cylindrical insert 2.
[0083] As Figure 2 shown in the embodiment of the second utility model in, the rotary housing 3 is mounted in a bearing on the toothed ring 5 such that when the drive device 1 is mounted to the cylindrical insert 2, the axis of rotation of the rotary housing 3 coincides with the axis of rotation of the control element 8 of the cylindrical insert 2.
[0084] In Figure 1 、 Figure 12 、 Figure 13 、 Figure 14 、 Figure 15 、 Figure 16 and Figure 17 shown in the embodiments of the second and fourth utility models in, the toothed ring 5 is provided with a central opening 7 through which the axis of rotation of the control element 8 extends, wherein the dimensions of the central opening 7 are such that the shoulder 152 of the key 15 can rotate freely relative to the toothed ring 5 during operation of the device. In the embodiment of the present utility model shown herein, the central opening has a circular shape, and it is obvious that in other embodiments it may have another shape, such as a hexagonal shape.
[0085] In addition, a first groove 10 extends through the central opening 7 in the toothed ring 5, and the first groove 10 has an elongated shape in its cross-section transverse to the axis of rotation of the rotary housing 3. This means that in this cross-section, the first groove 10 has a length greater than its width. At the same time, the length of the first groove 10 in the toothed ring 5 is not less than the width A of the head 151 of the key 15 for the cylindrical insert 2, and the width of the first groove 10 is not less than the thickness of the head 151 of the key 15. This length and width of the first groove 10 determine the possibility of introducing the head 151 of the key 15 into the key recess 11 through the toothed ring 5. In Figure 1 、 Figure 12 、 Figure 13 、 Figure 14 and Figure 15 shown in the embodiments of the second and fourth utility models in, the first groove 10 has the form of a rectangle with rounded corners, but it is obvious that in other embodiments of the present utility model, the first groove 10 may have another shape, for example, the long side may have a wavy form. Importantly, the outer dimensions of the first groove 10 enable the head 151 of the key 15 to be introduced through the toothed ring 5.
[0086] In Figure 1 、 Figure 12 、 Figure 13 、 Figure 14 、Figure 15 , Figure 16 and Figure 17 In the embodiments of the second and fourth utility models shown, the central opening 7 of the toothed ring 5 also has the function of fixing the position of the toothed ring 5 relative to the cylindrical part 61 of the body 6 of the cylindrical insert 2 of the lock, such that when the toothed ring 5 is mounted onto the cylindrical insert 2, the axis of rotation of the rotary housing 3 coincides with the axis of rotation of the control element 8. In order to position the toothed ring 5 relative to the cylindrical part 61 of the body 6 of the cylindrical insert 2, the first groove 10 is shaped such that the width of the first groove 10 at the point where it passes through the central opening 7 is less than the diameter of the cylindrical part 61 of the body 6 of the cylindrical insert 2.
[0087] In Figure 1 , Figure 12 , Figure 13 , Figure 14 , Figure 15 , Figure 16 and Figure 17 In the embodiments of the second and fourth utility models shown, the central opening 7 in the toothed ring 5 has a circular shape, and the length of the first groove 10 is greater than the diameter of the central opening 7 and the width of the first groove 10 is less than the diameter of the central opening 7. At the same time, the central opening 7 is dimensioned such that when the rotary housing 3 having the gear 7 is mounted onto the cylindrical insert 2 of the lock, the shoulder 152 of the key 15 can move freely relative to the toothed ring 5 within the central opening 7.
[0088] The toothed ring 5 is provided with a recess having a wall and a bottom at the side of the cylindrical insert 2, and when the toothed ring 5 is mounted relative to the body 6 of the cylindrical insert 2, the wall of the recess at least partially surrounds the body 6 of the cylindrical insert 2, such that the inner surface of the wall of the recess at least partially reflects a part of the outer surface of the end part of the body 6 of the cylindrical insert 2, and the central opening 7 is defined in the bottom of the recess such that the axis of the rotary control element 8 of the cylindrical insert 2 passes through the area of the central opening 7.
[0089] As Figure 13 , Figure 15 and Figure 16 shown in the embodiments of the fourth utility model shown, the toothed ring 5 has a mounting part 51 at the side opposite to the housing 3, the mounting part 51 includes three radially extending threaded mounting holes 52, and mounting screws 53 are arranged in the threaded mounting holes 52, wherein the mounting part 51 of the toothed ring 5 at least partially surrounds the end part of the body 6 of the cylindrical insert 2. It is also clear that the number of the mounting holes 52 and the mounting screws 53 in the toothed ring 5 can be different compared to other embodiments of the present utility model, and the manner of fixing the toothed ring 5 to the cylindrical insert 2 of the lock or the door leaf in which the lock is positioned can also be different.
[0090] As shown in the figure, inFigure 17 In the embodiment of the fourth utility model, the toothed ring 5 can be in two parts, and one element includes means for immovably fixing relative to the cylinder insert 2 of the lock, while the other element includes teeth 9. In this embodiment, the two parts are joined by using mounting screws 54.
[0091] According to the second and third utility models, for the rotating housing 3, a key recess 11 is provided on the side of the toothed ring 5. The key recess 11 is formed by a recess in the rotating housing 3, which is symmetric with respect to the rotation axis of the rotating housing 3, and the recess has the form of an elongated second groove 12 in its cross-section. The second groove 12 has a substantially elongated rectangular shape, and the longitudinal axis of the elongated rectangle extends through the rotation axis of the rotating housing 3. At the same time, the length of the second groove 12 in the rotating housing 3 is not less than the width A of the head 151 of the key 15 for the cylinder insert 2, and the width of the second groove 12 in the rotating housing 3 is not less than the thickness of the head 151 of the key 15 for the cylinder insert 2. Such length and width of the second groove 12 determine the possibility of introducing the head 151 of the key 15 into the key recess 11. At the same time, the lengths of the first groove 10 and the second groove 12 are greater than the diameter of the cylindrical part 61 of the body 6 of the cylinder insert 2, and thus greater than the diameter of the inscribed circle in the central opening 7. Of course, the depth of the recess 11 is greater than the length of the head 151 plus the length from the shoulder 152 of the key 15 to the outer end of the serrated part 153 of the key 15.
[0092] The first groove 10 in the toothed ring 5 is only used when the drive device 1 is fixed to the cylinder insert 2 of the lock. During this fixing process, it is important that the first groove 10 in the toothed ring 5 is set when rotating relative to the second groove 12 that defines the key recess 11, so that the head 151 of the key 15 can be introduced into the key recess 11 through the first groove 10. Then the first groove 10 and the second groove 12 are aligned.
[0093] After the head 151 of the key 15 is introduced through the toothed ring 5 and the drive device 1 is attached to the cylinder insert 2 of the lock, the key can rotate freely together with the rotary housing 3 relative to the toothed ring 5 within the central opening 7, because the shoulder 152 of the key 15 has a dimension smaller than the diameter of the central opening 7, and the head 151 of the key 15 is outside the area of the toothed ring 5 within the key recess 11. Thus, the central opening 7 can have dimensions much smaller than the required length of the first groove 10, and thus this construction does not weaken the toothed ring 5 in practice while providing a simple and intuitive way for mounting the drive device 1. The solution proposed in the present application also enables the toothed ring 5 to be positioned relative to the cylindrical part 61 of the cylinder insert 2, because due to the use of the first groove 10, the dimension of the inscribed circle in the central opening 7 can correspond to the diameter of the cylindrical part 61 of the cylinder insert 2, and at the same time the dimension of the inscribed circle in the central opening 7 can be significantly smaller than the dimension of the opening corresponding to the width A of the head 151 of the key 15, which is required to transfer the head 151 of the key 15 to the other side of the toothed ring 5.
[0094] To ensure the silent operation of the drive device 1, preferably, the width of the second groove 12 is only slightly larger than the thickness of the head 151 of the key 15 to limit the free angular movement of the rotary housing 3 relative to the head 151 of the key 15 at the start of the operation of the drive device 1.
[0095] As Figure 9 and Figure 11 shown in the embodiment of the third utility model in Figure 11 which, the plane including the axis of rotation of the rotary housing 3 and the longitudinal axis of the second groove 12 perpendicular thereto divides the rotary housing 3 into two parts, wherein, in one part of the rotary housing 3 located on one side of the plane dividing the rotary housing 3 into two parts, a drive motor 32 and a gear transmission 33 (as Figure 9 shown) are arranged, and the gear transmission 33 has an end gear 4 and a battery 34 having a cylindrical shape (as
[0096] shown). In the other part of the housing 3 located on the other side of the plane dividing the rotary housing into two parts, two batteries 34 having a cylindrical shape are arranged. These two batteries 34 in one part of the rotary housing 3 and one battery 34 in the other part constitute the electrical energy source 31.
[0096] The axis of the drive motor 32 and the axes of the cylindrical batteries 34 constituting the electrical energy source 31 are arranged parallel to the axis of rotation of the rotary housing 3 at a distance approximately equal from this axis, and in addition, the diameter of the drive motor 32 having a substantially cylindrical shape and the diameter of the cylindrical battery 34 are approximately equal, and this provides the compactness of the drive device 1.
[0097] The key recess 11 defined in the rotary housing 3, together with the key 15 inserted into the cylindrical insert 2 and the head 151 of the key 15 located within the key recess 11, constitutes a device for transmitting the driving force to the control element 8. The width of the second groove 12 and thus the width of the key recess 11 in the rotary housing 3 relative to the thickness of the head 151 of the key 15 are such that during the operation of the drive device 1, the rotary housing 3 rotates on the toothed ring 5 which is immovably arranged relative to the cylindrical insert 2 of the lock, and the rotary housing 3 pulls along the head 151 of the key 15 and rotates the shoulder 152 and the serrated portion 153 of the key 15 arranged in the control element 8 of the cylindrical insert 2.
