Description

Technical Field

[0001] The present application belongs to the technical field of intelligent security products, and specifically relates to a drive system and a lock. Background Art

[0002] With the advancement of science and technology and the improvement of people's living standards, locks, as an important tool to ensure safety, are constantly innovating and developing in terms of function and design.

[0003] At present, in order to meet the diverse usage needs of users, the locks sold on the market generally integrate two driving structures: manual drive parts and electric drive parts. The electric drive parts are, for example, motors. In actual use, users can manually rotate the manual drive parts to drive the lock cylinder of the lock to rotate, thereby controlling the opening or closing of the lock; or they can use the output shaft of the electric drive parts to automatically drive the lock cylinder to rotate, thereby achieving the purpose of controlling the opening or closing of the lock.

[0004] However, the locks sold on the market still have some defects, the most important of which is that when the manual drive part rotates, the output shaft of the electric drive part will also rotate, thereby increasing the wear of the electric drive part and thus shortening the service life of the electric drive part. Utility Model Content

[0005] The purpose of the embodiments of the present application is to provide a drive system and a lock that can solve the problem of short service life of electric drive components in related technologies.

[0006] In a first aspect, an embodiment of the present application provides a driving system for driving a lock core of a lock to rotate, comprising: an output member, the output member being used for transmission connection with the lock core;

[0007] A manual driving member, the manual driving member is drivingly connected to the output member;

[0008] An electric drive member and a planetary gear mechanism, wherein one of the output shaft of the electric drive member and the output member is drivingly connected to the ring gear of the planetary gear mechanism, and the other is drivingly connected to the sun gear of the planetary gear mechanism;

[0009] A locking mechanism, the locking mechanism being used to lock or unlock the planet carrier of the planetary gear mechanism;

[0010] Wherein, when the planetary carrier is in a locked state, the electric drive member can drive the output member to rotate through the planetary gear mechanism, and when the planetary carrier is in an unlocked state, the manual drive member can drive the output member to rotate and drive the planetary carrier to rotate through the sun gear or the ring gear, so that the transmission path between the manual drive member and the output shaft of the electric drive member is cut off.

[0011] In a second aspect, an embodiment of the present application further provides a lock, which includes a lock core and the driving system described above, wherein the output member is transmission-connected to the lock core to drive the lock core to rotate.

[0012] In the embodiment of the present application, when the planetary carrier is in a locked state, the electric drive member can drive the output member to rotate through the planetary gear mechanism, thereby driving the lock cylinder to rotate, and further controlling the opening or closing of the lock. When the planetary carrier is in an unlocked state, the manual drive member can drive the planetary carrier to rotate through the sun gear or the ring gear. The rotation of the planetary carrier means that the ring gear or the sun gear connected to the electric drive member cannot rotate, which means that the transmission path between the manual drive member and the output shaft of the electric drive member is cut off, so that the manual drive member cannot drive the output shaft of the electric drive member to rotate through the planetary gear mechanism. In this way, the wear of the electric drive member is reduced, thereby making the service life of the electric drive member longer. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiment is a moving part embodiment of the present application, rather than all embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of this application.

[0035] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0036] The drive system and lock provided in the embodiments of the present application are described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0037] Please refer to Figures 1 to 12 As shown, a driving system is provided in an embodiment of the present application, which is used to drive the lock core of the lock to rotate, including: an output member 210, a manual driving member 220, an electric driving member 310, a planetary gear mechanism 400 and a locking mechanism 500.

[0038] Specifically, the output member 210 is used to be in transmission connection with the lock core to drive the lock core to rotate synchronously.

[0039] The manual driving member 220 is in transmission connection with the output member 210 to drive the output member 210 to rotate synchronously.

[0040] One of the output shaft of the electric drive member 310 and the output member 210 is connected to the ring gear 430 of the planetary gear mechanism 400, and the other is connected to the sun gear 420 of the planetary gear mechanism 400. Figure 3 and Figure 4 As shown, the output shaft of the electric drive member 310 can be drivingly connected to the ring gear 430, and correspondingly, the output member 210 can be drivingly connected to the sun gear 420. Of course, the output shaft of the electric drive member 310 can also be drivingly connected to the sun gear 420, and correspondingly, the output member 210 can be drivingly connected to the ring gear 430.

[0041] The locking mechanism 500 is used to lock or unlock the planet carrier 410 of the planetary gear mechanism 400, wherein when the planet carrier 410 is in the locked state, the electric drive member 310 can drive the output member 210 to rotate through the planetary gear mechanism 400, and at this time, the transmission path between the electric drive member 310 and the output member 210 and the transmission path between the electric drive member 310 and the manual drive member 220 are both in a connected state. When the planet carrier 410 is in the unlocked state, the manual drive member 220 can drive the output member 210 to rotate, and drive the planet carrier 410 to rotate through the sun gear 420 or the ring gear 430, so that the transmission path between the manual drive member 220 and the output shaft of the electric drive member 310 is cut off.

[0042] In the embodiment of the present application, when the planetary carrier 410 is in a locked state, the electric drive member 310 can drive the output member 210 to rotate through the planetary gear mechanism 400, thereby driving the lock cylinder to rotate, and then controlling the opening or closing of the lock. When the planetary carrier 410 is in an unlocked state, the manual drive member 220 can drive the planetary carrier 410 to rotate through the sun gear 420 or the ring gear 430. The rotation of the planetary carrier 410 means that the ring gear 430 or the sun gear 420 connected to the electric drive member 310 cannot rotate, which means that the transmission path between the manual drive member 220 and the output shaft of the electric drive member 310 is cut off, so that the manual drive member 220 cannot drive the output shaft of the electric drive member 310 to rotate through the planetary gear mechanism 400, so that the wear of the electric drive member 310 is reduced, thereby making the service life of the electric drive member 310 longer.

[0043] Specifically, taking the example of the output shaft of the electric drive member 310 being transmission-connected with the ring gear 430 of the planetary gear mechanism 400, and the output member 210 being transmission-connected with the sun gear 420 of the planetary gear mechanism 400, in this case, for example, the first resistance that needs to be overcome by the manual drive member 220 to drive the planetary carrier 410 to rotate can be made smaller than the second resistance that needs to be overcome by the manual drive member 220 to drive the ring gear 430 to rotate, thereby achieving that when the planetary carrier 410 is in the unlocked state, the manual drive member 220 can drive the output member 210 to rotate, and drive the planetary carrier 410 to rotate through the sun gear 420.

[0044] More specifically, the planet carrier 410 is, for example, rotatably sleeved on the mounting shaft, and the first resistance is smaller than the second resistance by controlling the friction between the planet carrier 410 and the mounting shaft. In addition, in general, in order to make the rotation of the planet carrier 410 smoother, the friction between the planet carrier 410 and the mounting shaft is extremely small, almost zero, which is much smaller than the force required for the ring gear 430 or the sun gear 420 to drive the output shaft of the electric drive member 310 to rotate. In this case, when the planet carrier 410 is in the unlocked state, the rotation of the manual drive member 220 will drive one of the sun gear 420 and the ring gear 430 to rotate, and then one of the sun gear 420 and the ring gear 430 will drive the planet carrier 410 to rotate relative to the other of the sun gear 420 and the ring gear 430, while the other of the sun gear 420 and the ring gear 430 will remain stationary.

[0045] As a specific embodiment, the manual driving member 220 is, for example, a knob, the output member 210 is, for example, a cylindrical structure, the axes of the manual driving member 220, the output member 210 and the lock core are, for example, all the first axis, and the manual driving member 220, the output member 210 and the lock core are, for example, arranged in sequence along the first axis.

[0046] As a specific implementation, the electric drive component 310 is, for example, a power component such as a motor or an electric cylinder that needs to be powered to work.

[0047] It should be noted that the wear of the electric drive component 310 mentioned above refers to the wear of the components of the electric drive component 310. There is no doubt that the rotation of the output shaft of the electric drive component 310 will inevitably cause wear of one or more of its components, and usually, the more circles the output shaft rotates, the more serious the wear. Therefore, the solution adopted in this embodiment can reduce the wear of the electric drive component 310 by making the manual drive component 220 unable to drive the output shaft of the electric drive component 310 to rotate, thereby extending the service life of the electric drive component 310.

[0048] In addition, when the electric drive component 310 is a motor, the solution adopted in this embodiment can prevent the output shaft of the motor from rotating when the motor is powered off, thereby preventing the motor from generating reverse current, and further preventing a large reverse current from causing the motor to burn out.

[0049] Furthermore, the solution adopted in this embodiment cuts off the transmission path between the manual drive member 220 and the output shaft of the electric drive member 310. When the output member 210 is manually rotated, the resistance to the rotation of the output member 210 is small. In this way, the user can provide a smaller force to drive the lock cylinder to rotate, thereby providing a better user experience.

[0050] In another embodiment, reference Figures 3 to 8As shown, the locking mechanism 500 includes a moving member 510 and a driving assembly 520, the planet carrier 410 is provided with a clamping portion 4121, and the driving assembly 520 is connected to the moving member 510 and is used to drive the moving member 510 to reciprocate between a first position and a second position. When the moving member 510 is in the first position, the moving member 510 and the clamping portion 4121 are matched in the upper limit position in the rotation direction of the planet carrier 410, thereby locking the planet carrier 410, and when the moving member 510 is in the second position, the moving member 510 is separated from the clamping portion 4121, thereby realizing the unlocking of the planet carrier 410.

[0051] The solution adopted in this embodiment is that when the movable member 510 and the clamping portion 4121 are limited and matched, a connection relationship is established between the movable member 510 and the planetary carrier 410, thereby realizing the locking of the planetary carrier 410. Since the connection is not affected by external magnetic forces, the connection between the movable member 510 and the planetary carrier 410 is more reliable, thereby improving the stability of the planetary carrier 410.

[0052] In other optional embodiments, when the moving member 510 is in the first position, the moving member 510 may also be connected to the planet carrier 410 by magnetic attraction, thereby achieving locking of the planet carrier 410 .

[0053] In a further embodiment, reference Figures 3 to 8 As shown, the movable member 510 includes a first movable part 511, a second movable part 512 and an elastic member 513. The first movable part 511 is connected to the driving assembly 520, the second movable part 512 can be limitedly matched with the clamping part 4121 or separated from the clamping part 4121, the second movable part 512 is slidably matched with the first movable part 511 in the first direction, the first position and the second position are arranged in sequence along the first direction, and the second movable part 512 is connected to the first movable part 511 through the elastic member 513.

[0054] During specific use, due to the existence of processing errors and installation errors, when the driving assembly 520 has not yet driven the moving member 510 to move to the first position, the second moving portion 512 may have been limitedly matched with the clamping portion 4121, and the driving assembly 520 drives the moving member 510 to continue to move, and the second moving portion 512 will interfere with other components. In this case, since the second moving portion 512 is connected to the first moving portion 511 through the elastic member 513, the elastic member 513 can buffer the force between the second moving portion 512 and other components that interfere with the second moving portion 512, thereby preventing the driving assembly 520 from being stuck or damaged due to the large force between the second moving portion 512 and other components.

[0055] Furthermore, during specific use, when the second moving part 512 and the clamping part 4121 are staggered from each other, and the second moving part 512 and the planetary frame 410 are against each other, the moving member 510 is continuously driven to move toward the direction close to the connecting seat 412. Due to the presence of the elastic member 513, the first moving part 511 and the second moving part 512 can be close to each other, and the elastic member 513 can buffer the force between the first moving part 511 and the second moving part 512, thereby preventing the driving assembly 520 from being damaged due to excessive force. In addition, when the second moving part 512 and the clamping part 4121 are staggered from each other, and the elastic member 513 is in a compressed state, when the planetary frame 410 is rotated to adjust the positions of the second moving part 512 and the clamping part 4121 to be completely aligned, under the elastic force of the elastic member 513, the second moving part 512 can automatically engage with the clamping part 4121.

[0056] As a specific implementation, the first moving portion 511 and the second moving portion 512 are, for example, both plate-shaped structures, the elastic member 513 is, for example, a spring, and the clamping portion 4121 is, for example, a clamping groove.

[0057] In other optional embodiments, the moving member 510 may not include the second moving portion 512 and the elastic member 513 . In this case, the moving member 510 , for example, utilizes the first moving portion 511 to directly engage with the clamping portion 4121 or to separate from the clamping portion 4121 .

[0058] In a further embodiment, reference Figure 5 As shown, the second moving part 512 is located below the first moving part 511, and a sliding part 5121 is provided on one side of the second moving part 512 facing the first moving part 511, and the sliding part 5121 is slidably matched with the first moving part 511 in the first direction, and a connecting part 5114 is provided on one side of the first moving part 511 facing the second moving part 512, and the connecting part 5114 and the sliding part 5121 are sequentially arranged along the first direction, and the two ends of the elastic member 513 are respectively connected to the connecting part 5114 and the sliding part 5121, that is, the elastic member 513 extends along the moving direction of the moving member 510. In this way, the elastic member 513, the connecting part 5114 and the sliding part 5121 are centrally arranged between the first moving part 511 and the second moving part 512, so that the driving system as a whole is more compact and the spatial layout is more reasonable. Furthermore, the sliding portion 5121 in this embodiment simultaneously serves to install the elastic member 513 and to achieve sliding cooperation between the first movable portion 511 and the second movable portion 512. In this way, there is no need to add an additional structure on the second movable portion 512 for installing the elastic member 513, thereby making the overall structure of the drive system simpler and the cost lower.

[0059] In other optional embodiments, the elastic member 513 may also be arranged below the second movable portion 512. In this case, the connecting portion 5114, for example, extends to the bottom of the second movable portion 512, and a mounting member is provided on a side of the second movable portion 512 facing away from the first movable portion 511, for example, and the two ends of the elastic member 513 are respectively connected to the connecting portion 5114 and the mounting member.

[0060] In another embodiment, reference Figures 6 to 8 Shown, drive system also comprises housing 100, output member 210 and locking mechanism 500 are all located at housing 100, and output member 210 is connected with housing 100 for rotation, drive assembly 520 comprises: driving source 521, rotating member 522 and sliding member 523, driving source 521 is connected with rotating member 522, and is used to drive rotating member 522 to rotate, sliding member 523 is eccentrically located at rotating member 522, and slides with moving member 510 in the second direction, and the second direction intersects with the moving direction of moving member 510. Moving member 510 slides with housing 100 in the moving direction of moving member 510, to ensure that when rotating member 522 rotates, moving member 510 can move along its moving direction. So set, the power transmission path between rotating member 522, sliding member 523 and moving member 510 is shorter, thereby makes energy loss less.

[0061] During specific use, the rotating member 522 rotates, driving the sliding member 523 to slide along the second direction, thereby driving the moving member 510 to move in its moving direction relative to the housing 100 .

[0062] As a specific embodiment, the driving source 521 is, for example, a motor, the rotating member 522 is, for example, a turntable, the sliding member 523 is, for example, a cylindrical slide bar, and the second direction is, for example, perpendicular to the moving direction of the moving member 510. The first moving part 511 described above is, for example, provided with a first guide groove 5111 and a second guide groove 5112, the length direction of the first guide groove 5111 is, for example, the second direction, and the length direction of the second guide groove 5112 is, for example, the first guide groove 5111 is slidably matched with the sliding member 523 to achieve the sliding match between the sliding member 523 and the moving member 510 in the second direction, and the second guide groove 5112 is slidably matched with the second moving part 512 to achieve the sliding match between the second moving part 512 and the first moving part 511 in the first direction. The first movable part 511 is, for example, provided with a slide rail 5113, and the shell 100 includes, for example, a mounting seat 130, and the mounting seat 130 is, for example, provided with a slide groove. The slide rail 5113 slides with the slide groove to achieve sliding cooperation between the movable member 510 and the shell 100 in the moving direction of the movable member 510, and the second movable part 512 is, for example, slidably provided on the mounting seat 130.

[0063] In other optional embodiments, the driving source 521 may also be connected to the moving member 510 via a connecting rod mechanism.

[0064] In another embodiment, reference Figure 6 and Figure 7 As shown, the rotating member 522 is provided with an abutment portion 5221. The housing 100 is provided with a first stopper 110. When the moving member 510 is in the first position, the abutment portion 5221 cooperates with the first stopper 110 in the upper limit position of the first rotation direction of the rotating member 522; and / or, the housing 100 is provided with a second stopper 120. When the moving member 510 moves to the second position, the abutment portion 5221 cooperates with the second stopper 120 in the upper limit position of the second rotation direction of the rotating member 522. Specifically, the housing 100 may be provided with both the first stopper 110 and the second stopper 120, or may be provided with the first stopper 110 or the second stopper 120 alone. The second rotation direction and the first rotation direction are opposite in direction. In this way, when the abutment portion 5221 cooperates with the first limit member 110, it means that the movable member 510 moves to the first position, and when the abutment portion 5221 cooperates with the second limit member 120, it means that the movable member 510 moves to the second position. In this way, with the help of the first limit member 110 and the second limit member 120, the user can more accurately judge whether the movable member 510 moves to the first position or the second position.

[0065] As a specific implementation, the abutting portion 5221 is, for example, an abutting block, the first limiting member 110 is, for example, a first limiting block, and the second limiting member 120 is, for example, a second limiting block.

[0066] In other optional embodiments, the housing 100 may not be provided with the first limiting member 110 and the second limiting member 120 .

[0067] In another embodiment, reference Fig. 9 and Fig.10 As shown, the planet carrier 410 includes: a frame body 411 and a connecting seat 412 connected to each other, the frame body 411 is arranged inside the gear ring 430, and is rotatably connected to the planetary gear 450 of the planetary gear mechanism 400, the connecting seat 412 is sleeved on the outside of the gear ring 430, and the number of the clamping parts 4121 is at least two, each clamping part 4121 is arranged on the connecting seat 412, and each clamping part 4121 is sequentially arranged along the circumference of the connecting seat 412. In this way, the number of the clamping parts 4121 is at least two, so that there are multiple positions where the moving part 510 and the planet carrier 410 can be limited and matched, so that the user can flexibly adjust the position of the planet carrier 410, so that the drive system is more convenient to use and the user experience is better.

[0068] In other optional embodiments, the number of the clamping portion 4121 can also be one.

[0069] As a specific implementation method, refer to Fig.10 As shown, the ring gear 430 includes, for example, at least two first teeth and at least two second teeth, each of the first teeth is arranged on the outer wall of the ring gear 430 and is arranged in sequence along the circumference of the ring gear 430, each of the second teeth is arranged on the inner wall of the ring gear 430 and is arranged in sequence along the circumference of the ring gear 430, the first teeth are used for transmission connection with the electric drive member 310, for example, the second teeth are meshed with the planetary gear 450, so as to realize the transmission connection between the ring gear 430 and the planetary gear 450.

[0070] As a specific implementation method, refer to Fig.10 As shown, the planetary gear mechanism 400 includes at least two planetary gears 450, each of which is arranged inside the ring gear 430 and is arranged in sequence along the circumference of the ring gear 430. Each planetary gear 450 is rotatably connected to the planetary carrier 410 through a connecting shaft 440, and the frame 411 and the connecting seat 412 are connected, for example, through the connecting shaft 440. The specific number of the planetary gears 450 depends on actual needs. The number of the planetary gears 450 in the figure is specifically three.

[0071] In another embodiment, reference Figure 3 and Figure 5 As shown, the driving system further includes: a control element 610 and an angle detection device 620 . The angle detection device 620 is used to detect the rotation angle of the output member 210 , and the angle detection device 620 is communicatively connected with the control element 610 .

[0072] During specific use, the angle detection device 620 transmits the angle information it detects to the control element 610, and the control element 610 processes the information for use by the user. The user can understand the specific angle of the output member 210 based on this information, and thus can understand the specific angle of the lock core, and further can know what state the lock is in. It can be seen that the solution adopted in this embodiment allows the user to understand what state the lock is in, so that the user experience is better and the lock is more convenient to use.

[0073] As a specific implementation, the angle detection device 620 is, for example, an angle sensor. More specifically, the angle sensor is, for example, a Hall sensor. The control element 610 is, for example, a circuit board. The angle sensor is, for example, directly disposed on the control element 610 .
