lock control device

Abstract

The application relates to a lock control device which comprises a host, a driving mechanism, an adjusting mechanism and a clamping mechanism. The driving mechanism is rotationally arranged on the host. The adjusting mechanism comprises a fixing base, a fixing base and an adjusting assembly. The fixing base is fixedly connected with the driving mechanism. The adjusting assembly is arranged on the fixing base and can slide along multiple sliding directions relative to the fixing base. The multiple sliding directions of the adjusting assembly are perpendicular to the axis around which the driving mechanism rotates. The clamping mechanism is fixedly connected with the adjusting assembly and is used for clamping an unlocking knob on a door body. Since the adjusting assembly can slide along multiple sliding directions relative to the fixing base, the sliding direction of the clamping mechanism relative to the fixing base has multiple different choices, that is, the position adjusting range of the adjusting mechanism to the clamping mechanism is greatly improved, so that the clamping mechanism accurately moves to a specified position and is accurately aligned with the unlocking knob of a traditional door lock. Therefore, the cooperation precision between the clamping mechanism and the entire lock control device and the knob is improved.

Description

Technical Field

[0001] This application relates to the field of smart lock technology, and in particular to a keyhole device. Background Technology

[0002] Smart locks are widely used due to their convenience and security. However, when choosing a smart lock, some users do not want to replace their existing doors or the non-smart traditional locks on them. Therefore, the lock control device can be installed on the traditional lock, and the smart lock can drive the knob of the traditional lock to turn, thereby realizing the intelligent transformation of the traditional lock.

[0003] Due to differences in usage habits and technical standards, the unlocking knobs of traditional door locks vary considerably in style across different countries and regions. Traditional lock control devices often have the drawback of being difficult to align with the unlocking knob, thus affecting the accuracy of the fit between the lock control device and the unlocking knob.

After the main unit is fixed, the adjusting mechanism can drive the clamping mechanism to move accurately to the designated position and precisely align it with the unlocking knob of a traditional door lock. This improves the matching accuracy between the clamping mechanism and the entire lock control device and the unlocking knob. Attached Figure Description

Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0034] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0035] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0036] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0037] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0038] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0039] See Figure 1 , Figure 2 and Figure 3 One embodiment of this application provides a lock control device 10 for installation on the unlocking knob of a traditional door lock. The unlocking knob of a traditional door lock is installed on the indoor side of the door, allowing the user to unlock and lock the door by rotating it. The lock control device 10 provided in this application is installed on the unlocking knob of a traditional door lock and can drive the unlocking knob to rotate electrically or manually, thereby achieving automatic or manual unlocking and locking of the traditional door lock.

[0040] The lock control device 10 includes a main unit 11, a drive mechanism 12, an adjustment mechanism 13, and a clamping mechanism 14. The drive mechanism 12 is rotatably connected to the main unit 11, and the adjustment mechanism 13 is fixedly connected to the drive mechanism 12. The adjustment mechanism 13 can rotate synchronously with the drive mechanism 12 relative to the main unit 11. The clamping mechanism 14 is fixedly connected to the adjustment mechanism 13, so that the clamping mechanism 14 can rotate synchronously with the adjustment mechanism 13 relative to the main unit 11. Therefore, both the clamping mechanism 14 and the adjustment mechanism 13 can rotate synchronously with the drive mechanism 12 relative to the main unit 11. The clamping mechanism 14 is used to clamp the unlocking knob of a traditional door lock. When the drive mechanism 12 rotates relative to the main unit 11, the adjustment mechanism 13, the clamping mechanism 14, and the clamped unlocking knob will all rotate synchronously with the drive mechanism 12. That is, the drive mechanism 12 will drive the unlocking knob of the traditional door lock to rotate through the adjustment mechanism 13 and the clamping mechanism 14, thereby realizing the locking and unlocking of the traditional door lock.

[0041] In an optional embodiment, the main unit 11 includes a main unit housing and an electric drive device. A drive mechanism 12 is rotatably connected to the main unit housing. The electric drive device is located inside the main unit housing and is drive-connected to the drive mechanism 12. The electric drive device can be a motor. The main unit 11 also includes a communication unit and a control unit. The communication unit receives lock / unlock signals, and the control unit controls the electric drive device inside the main unit housing based on the lock / unlock signals to drive the driver 12 and the clamping mechanism 13 to rotate, thus achieving electric unlocking and locking. The drive mechanism 12 can rotate relative to the main unit 11 under the drive of the electric drive device within the main unit 11, or it can rotate relative to the main unit 11 under manual operation. Optionally, a clutch device is provided between the electric drive device and the drive mechanism 12, which prevents interference between manual and electric rotation of the drive mechanism 12.

[0042] Since the unlocking knob is located indoors, the main unit 11, drive mechanism 12, adjustment mechanism 13, and clamping mechanism 14 are all installed on the indoor side of the door. When the drive mechanism 12 rotates relative to the main unit 11, it drives the unlocking knob of the traditional door lock to rotate through the adjustment mechanism 13 and clamping mechanism 14, thereby realizing the unlocking and locking of the traditional door lock.

[0043] The lock control device of this application has two locking and unlocking methods: manual and electric. ① The user can manually rotate the drive mechanism 12, causing it to rotate the connected adjustment mechanism 13 and clamping mechanism 14, thereby rotating the unlocking knob to achieve manual locking and unlocking. ② The drive mechanism 12 can be rotated by an electric drive device inside the main unit, which in turn rotates the connected adjustment mechanism 13 and clamping mechanism 14, thereby rotating the unlocking knob to achieve electric locking and unlocking. In an optional embodiment, the lock control device 10 may also include a control panel installed outdoors. The control panel can receive locking and unlocking commands via password, fingerprint, Bluetooth, or NFC (Near Field Communication), and upon receiving the lock and unlocking command, it sends a lock and unlocking signal to the indoor main unit 11. After receiving the lock and unlocking signal, the control unit inside the main unit 11 activates the electric drive device to rotate the drive mechanism 12, adjustment mechanism 13, clamping mechanism 14, and unlocking knob. Of course, the switch signal can also be sent directly to the indoor host 11 via remote control, so that the electric drive device in the host 11 drives the drive mechanism 12, the adjustment mechanism 13, the clamping mechanism 14 and the unlocking knob to rotate.

[0044] See Figure 3 , Figure 4 and Figure 5In some embodiments, the adjusting mechanism 13 includes a fixed base 100 and an adjusting component 201. The fixed base 100 can be connected to the driving mechanism 12 via a drive mechanism, for example, by bolts or snap-fit ​​connections. The adjusting component 201 is mounted on the fixed base 100 and can slide relative to the fixed base 100 in multiple sliding directions. These multiple sliding directions are perpendicular to the axis around which the driving mechanism 12 rotates. The clamping mechanism 14 is fixedly connected to the adjusting component 201 and is used to clamp the unlocking knob on the door. For example, the adjusting component 201 can slide relative to the fixed base 100 along multiple straight lines extending in different directions; or, for example, the adjusting component 201 can slide relative to the fixed base 100 along multiple curves extending in different directions; or, for example, the adjusting component 201 can slide relative to the fixed base 100 along multiple curves and multiple straight lines extending in different directions.

[0045] If the adjusting component 201 and the fixed base 100 are slid in a single direction, the movement direction of the clamping mechanism 14 relative to the fixed base 100 is limited. That is, the adjustment range of the position of the clamping mechanism 14 by the adjusting mechanism 13 is limited. Therefore, the clamping mechanism 14 will be difficult to move to the designated position and accurately align with the unlocking knob of the traditional door lock. When the clamping mechanism 14 clamps the unlocking knob, it will inevitably affect the installation accuracy of the clamping mechanism 14 and the entire lock control device 10.

[0046] See Figure 3 , Figure 4 and Figure 5 Regarding the lock control device 10 in the above embodiments, since the adjusting component 201 can slide relative to the fixed base 100 in multiple sliding directions, the sliding direction of the clamping mechanism 14 relative to the fixed base 100 can be selected in various ways. That is, the adjustment range of the clamping mechanism 14 by the adjusting mechanism 13 is greatly improved. After the main unit is fixed on the door, the clamping mechanism 14 can be accurately moved to the designated position by the adjusting mechanism 13 to accurately align with the unlocking knob of the traditional door lock. This improves the matching accuracy between the clamping mechanism 14 and the entire lock control device 10 and the unlocking knob, so that the entire lock control device 10 can better drive the unlocking knob to rotate.

[0047] In some embodiments, the multiple sliding directions of the adjusting component include a first direction and a second direction arranged at an angle, both of which are perpendicular to the axis around which the driving mechanism 12 rotates. The adjusting component 201 includes a first slider 200 and a second slider 300. The first slider 200 is slidably connected to the fixed base 100 along a first curve 101, and the second slider 300 is slidably connected to the first slider 200 along a second curve 102. The first curve 101 extends generally in the first direction, and the second curve 102 extends generally in the second direction. The clamping mechanism 14 is connected to the second slider 300. The first curve 101 extending in the first direction has multiple tangents, so the first slider 200 can move relative to the fixed base 100 in multiple different directions. Similarly, the second curve 102 extending in the second direction also has multiple tangents, so the second slider 300 can move relative to the first slider 200 in multiple different directions. Ultimately, the clamping mechanism 14 can follow the second slider 300 in moving in multiple directions relative to the fixed base 100. This allows for multiple options in the sliding direction of the clamping mechanism 14 relative to the fixed base 100, significantly increasing the position adjustment range of the clamping mechanism 14 by the adjusting mechanism 13, enabling the clamping mechanism 14 to move accurately to the designated position and align precisely with the unlocking knob of the traditional door lock.

[0048] In other embodiments, the multiple sliding directions of the adjusting component include a first direction and a second direction arranged at an angle, both of which can be perpendicular to the axis around which the drive mechanism 12 rotates. The adjusting component 201 includes a first slider 200 and a second slider 300. The first slider 200 can be slidably connected to the fixed base 100 along a first straight line, and the second slider 300 can be slidably connected to the first slider 200 along a second straight line. The first straight line extends in the first direction, and the second straight line extends in the second direction. The first straight line and the second straight line can be perpendicular or non-perpendicular, that is, the first straight line and the second straight line can form a right angle or an acute angle.

[0049] See Figure 6 , Figure 7 and Figure 8 In some embodiments, the adjustment mechanism 13 further includes a first guide member 410. One of the first sliding member 200 and the fixed seat 100 is fixedly connected to the first guide member 410 and the other has a first groove 110. The first groove 110 extends along a first curve 101 extending in a first direction. The first guide member 410 and the first groove 110 slide in cooperation, thereby realizing that the first sliding member 200 slides along the first curve 101 and the fixed seat 100.

[0050] In one embodiment, the first groove 110 may be formed on the fixed base 100, and the first guide member 410 is fixedly connected to the first sliding member 200. In another embodiment, the first groove 110 may also be formed on the first sliding member 200, and the first guide member 410 is fixedly connected to the fixed base 100. Furthermore, the first guide member 410 extends into the first groove 110 and can slide along the first groove 110.

[0051] See Figure 6 , Figure 7 and Figure 8 In some embodiments, the first guide member 410 includes a first guide rod 411 and a first guide cap 412 connected together. The first guide rod 411 and the first guide cap 412 are coaxially arranged, and the cross-section of the first guide cap 412 is larger than the cross-section of the first guide rod 411. A first groove 110 is formed on the fixed base 100 and extends through the fixed base 100 along the thickness direction. The first groove 110 includes a first groove 111 and a second groove 112. Obviously, both the first groove 111 and the second groove 112 extend along the first curve 101. The second groove 112 is formed in the middle region of the bottom wall surface of the first groove 111, that is, the second groove 112 can be formed by recessing the middle region of the bottom wall surface of the first groove 111. The edge portion of the bottom wall surface of the first groove 111 forms a first stepped surface 113 because it is not recessed. The first stepped surface 113 surrounds the second groove 112. Obviously, the groove width of the second groove 112 is smaller than the groove width of the first groove 111. The second groove 112 is positioned closer to the first sliding member 200 than the first groove 111. The first guide rod 411 slides through the second groove 112 and is fixedly connected to the first sliding member 200. The first guide cap 412 slides within the first groove 111 and is located outside the second groove 112, abutting against the first stepped surface 113. Given that the first guide rod 411 is fixedly connected to the first sliding member 200 and the first guide cap 412 abuts against the first stepped surface 113, the fixing seat 100 is thus sandwiched between the first sliding member 200 and the first guide cap 412. The interference between the fixing seat 100 and the first guide cap 412 effectively prevents the first sliding member 200 from detaching from the fixing seat 100. Furthermore, the first guide rod 411 can slide in the second groove 112, and the first guide cap 412 can slide in the first groove 111, ensuring that the first sliding member 200 slides relative to the fixed seat 100 along the extension direction of the first sliding groove 110.

[0052] See Figure 6 , Figure 7 and Figure 8In some embodiments, the first sliding member 200 includes a first sliding body 220 and a first boss 230. The first boss 230 protrudes from the surface of the first sliding body 220 facing the fixed seat 100. The first boss 230 is slidably engaged with the second groove 112, and a first guide rod 411 is inserted into the first boss 230 and fixedly connected to the first boss 230. For example, the first guide member 410 can be a bolt, and the first guide rod 411 can be the thread of the bolt. By sliding the first boss 230 with the second groove 112, the first boss 230 contacts the inner wall surface of the second groove 112, which can effectively prevent the threaded first guide member 410 from contacting the inner wall surface of the second groove 112, thereby reducing the frictional resistance of the first sliding member 200 relative to the fixed seat 100 during sliding. At the same time, it can also reduce the vibration generated by the first sliding member 200 during sliding, thereby improving the sliding accuracy of the first sliding member 200 and also improving the position adjustment accuracy of the entire adjustment mechanism 13 to the clamping mechanism 14. For example, the first guide component 410 can also be a rivet, etc.

[0053] See Figure 6 , Figure 9 and Figure 10 In some embodiments, the adjustment mechanism 13 further includes a second guide 420. One of the second slider 300 and the first slider 200 is fixedly connected to the second guide 420, and the other has a second groove 210. The second groove 210 extends along a second curve 102 extending in a second direction. The second guide 420 and the second groove 210 slide in cooperation, thereby realizing that the second slider 300 slides along the second curve 102 and the first slider 200 are slidably connected.

[0054] In one embodiment, the second groove 210 may be formed on the first slider 200, and the second guide 420 is fixedly connected to the second slider 300. In another embodiment, the second groove 210 may also be formed on the second slider 300, and the second guide 420 is fixedly connected to the first slider 200. Furthermore, the second guide 420 extends into the second groove 210 and can slide along the second groove 210.

[0055] See Figure 6 , Figure 9 and Figure 10In some embodiments, the second guide member 420 includes a second guide rod 421 and a second guide cap 422 connected together. The second guide rod 421 and the second guide cap 422 are coaxially arranged, and the cross-section of the second guide cap 422 is larger than the cross-section of the second guide rod 421. A second groove 210 is formed on the first sliding member 200. The second groove 210 penetrates the first sliding member 200 along the thickness direction. The second groove 210 includes a third groove 211 and a fourth groove 212. Obviously, both the third groove 211 and the fourth groove 212 extend along the second curve 102 extending in the second direction. The fourth groove 212 is formed in the middle region of the bottom wall surface of the third groove 211, that is, the fourth groove 212 can be formed by recessing the middle region of the bottom wall surface of the third groove 211. The edge portion of the bottom wall surface of the third groove 211 forms a second stepped surface 213 because it is not recessed. The second stepped surface 213 surrounds the fourth groove 212. Obviously, the groove width of the fourth groove 212 is smaller than the groove width of the third groove 211. The third groove 211 is positioned closer to the first sliding member 200 than the fourth groove 212. The second guide rod 421 slides through the fourth groove 212 and is fixedly connected to the second sliding member 300. The second guide cap 422 slides within the third groove 211 and is located outside the fourth groove 212, abutting against the second step surface 213. Given that the second guide rod 421 is fixedly connected to the second sliding member 300 and the second guide cap 422 abuts against the second step surface 213, the first sliding member 200 is thus sandwiched between the second sliding member 300 and the second guide cap 422. The interference between the first sliding member 200 and the second guide cap 422 effectively prevents the second sliding member 300 from detaching from the first sliding member 200. Furthermore, the second guide rod 421 can slide in the fourth groove 212, and the second guide cap 422 can slide in the third groove 211, ensuring that the second slider 300 slides relative to the first slider 200 along the extension direction of the second groove 210.

[0056] See Figure 6 , Figure 9 and Figure 10In some embodiments, the second sliding member 300 includes a second sliding body 320 and a second boss 330, and a second groove 210 is formed on the second sliding body 320. The second boss 330 protrudes from the surface of the second sliding body 320 facing the first sliding member 200. The second boss 330 is slidably engaged with the fourth groove 212, and a second guide rod 421 is inserted into the second boss 330 and fixedly connected to the second boss 330. For example, the second guide member 420 can be a bolt, and the second guide rod 421 can be the threaded part of the bolt. By sliding the second boss 330 into the fourth groove 212, the inner wall surface of the second boss 330 and the fourth groove 212 come into contact. This effectively prevents the threaded second guide member 420 from contacting the inner wall surface of the fourth groove 212, thereby reducing the frictional resistance of the second sliding member 300 relative to the first sliding member 200 during the sliding process. It also reduces the vibration generated by the second sliding member 300 during sliding, thus improving the sliding accuracy of the second sliding member 300 and the position adjustment accuracy of the entire adjusting mechanism 13 relative to the clamping mechanism 14. Alternatively, the second guide member 420 can also be a rivet, etc.

[0057] See Figure 4 and Figure 5 In some embodiments, the first slide groove 110 is formed on the fixed base 100, and the second slide groove 210 is formed on the first sliding member 200. The second slide groove 210 has an orthographic projection on the fixed base 100. The orthographic projection of the second slide groove 210 and the first slide groove 110 are spaced apart, so that there is no intersection or overlap between the projection of the second slide groove 210 and the first slide groove 110. This effectively prevents the first sliding member 200 and the second sliding member 300 from interfering with each other during the sliding process along different curves, and improves the smoothness of the adjustment mechanism 13 in the position adjustment process of the clamping mechanism 14.

[0058] See Figure 4 and Figure 5 In some embodiments, there are two first slide grooves 110 and two second slide grooves 210, so there are also two orthographic projections of the second slide grooves 210. This reduces the shaking generated by the first sliding member 200 and the second sliding member 300 during the sliding process, reduces the occurrence of jamming, and improves the sliding accuracy and smoothness of both. Furthermore, the orthographic projections of the two first slide grooves 110 and the two second slide grooves 210 are spaced apart along the rotation direction of the drive mechanism 12, and there is a first slide groove 110 between the orthographic projections of two second slide grooves 210 that are adjacent in the rotation direction of the drive mechanism 12, thereby further reducing the interference generated by the first sliding member 200 and the second sliding member 300 during the sliding process, thereby improving the smoothness of the adjustment mechanism 13 in the position adjustment process of the clamping mechanism 14.

[0059] See Figure 3 and Figure 5 In some embodiments, the drive mechanism 12 is mounted on the host 11 around a rotation axis. With reference to the extension direction of the rotation axis of the drive mechanism 12, the fixed base 100, the first sliding member 200, and the second sliding member 300 are stacked on top of each other. This can reasonably reduce the space occupied by the adjustment mechanism 13, thereby improving the structural compactness of the adjustment mechanism 13 and the entire locking device 10, thus achieving a miniaturized design of the locking device 10.

[0060] See Figure 3 and Figure 4 In some embodiments, a limiting hole 11a is recessed on the outer surface of the host 11. The first slider 200 and the second slider 300 are rotatably disposed in the limiting hole 11a. At least a portion of the peripheral surfaces of the first slider 200 and the second slider 300 can maintain a distance from the inner wall of the limiting hole 11a, allowing the first slider 200 and the second slider 300 to slide within the limiting hole 11a. It can be understood that when a portion of the peripheral surface of the first slider 200 or the second slider 300 contacts the inner wall of the limiting hole 11a, the first slider 200 or the second slider 300 will stop sliding. Therefore, by providing the limiting hole 11a, the maximum sliding stroke of the first slider 200 or the second slider 300 can be limited, preventing the adjustment mechanism 13 from adjusting the position of the clamping mechanism 14 too much.

[0061] See Figure 1 , Figure 2 and Figure 3 In some embodiments, the drive mechanism 12 includes an operation knob 12a and a knob shaft 12b. The operation knob 12a may be at least partially located outside the main unit 11. The operation knob 12a and the fixed base 100 are located on opposite sides of the main unit 11, so that the operation knob 12a and the entire adjustment mechanism 13 can be located on opposite sides of the main unit 11. The knob shaft 12b is at least partially housed inside the main unit 11, that is, the knob shaft 12b is inserted into the main unit 11. The knob shaft 12b is fixedly connected to both the operation knob 12a and the fixed base 100, so that the knob shaft 12b is connected between the operation knob 12a and the fixed base 100. The knob shaft 12b may be fixedly connected to the fixed base 100 by bolts 500. For example, the fixed base 100 may be provided with a fixing hole, and the bolt may be housed in the fixing hole and threadedly connected to the end of the knob shaft 12b.

[0062] The knob shaft 12b can be a gear or similar component. The electric drive unit of the main unit 11 can drive the knob shaft 12b to rotate, causing the operating knob 12a, adjustment mechanism 13, and clamping mechanism 14 to rotate synchronously with the knob shaft 12b. In this way, the unlocking knob is rotated to achieve electric unlocking and locking of the traditional door lock. Of course, the operating knob 12a can also be manually rotated, causing the operating knob 12a to drive the adjustment mechanism 13 and clamping mechanism 14 to rotate via the knob shaft 12b, thus achieving manual unlocking and locking of the traditional door lock.

[0063] See Figure 3 and Figure 5 In some embodiments, the second sliding member 300 further includes a positioning post 341 and a fixing member 342. Both the positioning post 341 and the fixing member 342 protrude from the surface of the second sliding body 320 facing away from the first sliding member 200. The positioning post 341 is inserted into the clamping mechanism 14, thus achieving positioning of the clamping mechanism 14 and improving its installation efficiency and accuracy. The fixing member 342 can be detachably connected to the clamping mechanism 14, for example, through a snap-fit ​​connection, thus achieving a fixed connection between the clamping mechanism 14 and the second sliding member 300.

For the sake of brevity, 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.
