Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments herein without making any creative effort, shall fall within the scope of protection.

It should be noted that the terms "first," "second," and the like in the description and claims herein and in the above-described drawings are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments herein described are capable of operation in sequences other than those illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, apparatus, article, or device that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or device.

In the prior art, in order to avoid falling off of the charging gun from the power receiving socket and avoid electric shock hazard caused by the falling off of the charging gun from the power receiving socket during charging, an electronic lock is required to be arranged on a charging plug of the charging gun and the power receiving socket of a vehicle, so that the charging gun is firmly locked on the power receiving socket of the vehicle in the charging process. However, in the prior art, most position detection devices for acquiring whether the electronic lock is in a locked state or an unlocked state are complex in structure, large in size, high in cost and difficult to popularize; and current electronic lock is mostly mechanical trigger formula, to complicated operating mode, and current position detection device is difficult to realize the continuous detection to the locking lever position.

In order to solve the above problems, embodiments herein provide an electronic lock, which has a simple and compact structure and can achieve accurate and continuous detection of the position of a lock lever. Specifically, as shown in fig. 1, the electronic lock includes a housing (not shown in fig. 1), a motor 40, a transmission structure, a magnetic device 30 (not shown in fig. 1), a lock lever 50, and a position detecting structure 60;

the transmission structure is connected with the motor 40 and the lock bar 50, and the magnetic device 30 or the position detection structure 60 is arranged at the transmission structure; the corresponding position detection structure 60 or magnetic device 30 is disposed within the housing;

the transmission structure is used for driving the lock rod 50 to move under the driving of the motor 40 so as to perform locking or unlocking actions, and driving the magnetic device 30 or the position detection structure 60 to synchronously rotate so as to change the relative position of the magnetic device 30 to the position detection structure 60;

the position detecting structure 60 is used to detect the position of the locking bar 50 according to the change of its relative position with respect to the magnetic device 30.

Namely, the transmission structure is used for converting the rotary motion output by the motor into the lifting movement of the lock rod 50 to realize locking or unlocking, and is also used for enabling the magnetic device 30 or the position detection structure 60 to generate relative position change; and since the driving action of the driving mechanism to the lock lever 50 and the driving action to the magnetic device 30 or the position detecting mechanism 60 are synchronized, the relative position change of the magnetic device 30 and the position detecting mechanism 60 is associated with the lifting movement of the lock lever 50.

When the magnetic device 30 and the position detecting structure 60 change relatively, the magnetic field generated by the magnetic device 30 detected by the position detecting structure 60 also changes, and then the position detecting structure 60 generates a changed induced current, and sends the position change information of the two to be known by an operator or the vehicle ECU. Since the position change information of the two is related to the position of the lock lever 50, that is, the position information of the lock lever 50 is transmitted, the lock lever 50 is positioned.

In some specific embodiments, the transmission structure may include a first transmission structure 10 and a second transmission structure 20;

as shown in fig. 1 to 4, one end of the first transmission structure 10 is connected to an output shaft 41 of the motor 40, and the other end of the first transmission structure 10 is connected to one end of the second transmission structure 20; the other end of the second transmission structure 20 is connected with the lock rod 50;

the magnetic device 30 is disposed on the second transmission structure 20, and the position detecting structure 60 is disposed on a side of the housing close to the second transmission structure 20.

That is, the position detecting structure 60 is disposed close to the magnetic device 30 to detect the change of the magnetic field of the magnetic device 30 due to the position change more sensitively, thereby generating a more accurate induced current to more accurately feed back the position information of the locking lever 50.

In other embodiments, the position detecting structure 60 is disposed on the second transmission structure 20, and the magnetic device 30 is disposed on a side of the housing adjacent to the second transmission structure 20.

In some particular embodiments, the first transmission 10 comprises a first driving wheel 11 and a first driving rod 12;

the first transmission rod 12 is fixedly connected with the first transmission wheel 11 and synchronously rotates with the first transmission wheel 11, the first transmission wheel 11 is in transmission connection with the output shaft 41, and the end part of the first transmission rod 12 extending out of the first transmission wheel 11 is connected with the second transmission structure 20.

Specifically, the first driving rod 12 is connected to a circle center of the first driving wheel 11, and an axial direction of the first driving rod 12 is perpendicular to a rotation plane of the first driving wheel 11. The first driving wheel 11 is in driving connection with the output shaft 41, that is, the output shaft 41 is parallel to the first driving rod 12.

Further, as shown in fig. 3, a first engaging tooth 111 is provided on an outer side surface of the first driving wheel 11, and the engaging tooth on the output shaft 41 engages with the first engaging tooth 111 to realize the driving. The meshing transmission mode can ensure high transmission stability and reliability, and has high transmission efficiency, quick response and long service life; when the output shaft 41 of the motor 40 rotates in the first direction in the first period, the first driving wheel 11 can rotate in the direction (referred to as the second direction) opposite to the first direction in the first period; the first driving wheel 11 can be made to respond quickly and rotate in the first direction for the second period, which alternate with each other, when the output shaft 41 rotates in the second direction for the second period. Further, by setting the number of teeth and the rotation radius of the output shaft 41 rotating once, and the number of teeth of the first meshing teeth 111 on the outer peripheral surface of the first drive wheel 11 and the rotation radius of the first drive wheel 11, a constant rotation speed and torque can be obtained.

In the embodiment of the specification, the transmission ratio of the motor output shaft 41 to the first transmission wheel 11 is greater than 1; the rotational radius of the output shaft 41 is smaller than the rotational radius of the first drive wheel 11. That is, the first transmission wheel 11 is a reduction gear, and the first transmission structure 10 can reduce the rotation speed output by the motor 40 and increase the torque, so as to easily drive the lock rod 50 to move, prevent the lock rod 50 from exceeding the displacement limit when the lock rod 50 is driven by the larger rotation speed output by the motor 40 to linearly reciprocate, and prevent the lock rod 50 and surrounding parts from being damaged.

As shown in fig. 1 and 4, the second transmission structure 20 comprises a second transmission wheel 21, a second transmission rod 22 and a driving rod 23;

the second transmission wheel 21 is fixedly connected with the second transmission rod 22 and rotates around the second transmission rod 22, one end of the driving rod 23 is fixedly connected with the second transmission wheel 21, and one end of the driving rod 23, which is far away from the second transmission wheel 21, is fixedly connected with the second transmission rod 22; i.e. the second transmission wheel 21 and the drive rod 23, rotate about the second transmission wheel 21.

The second transmission wheel 21 is in transmission connection with the first transmission rod 12, and the driving rod 23 is connected with the lock rod 50 for driving the lock rod 50 to do linear motion.

In some possible embodiments, the second transmission rod 22 can be connected to the housing of the electronic lock through the second transmission wheel 21, i.e. the second transmission rod 22 is fixed to avoid the second transmission wheel 21 from being displaced during the rotation process, thereby ensuring the stability of the transmission of the rotation force.

The second transmission wheel 21 is in transmission connection with the first transmission rod 12, and the driving rod 23 is connected with the lock rod 50 for driving the lock rod 50 to do linear motion. That is, the rotating power output by the output shaft of the motor 40 is sequentially transmitted to the lock lever 50 through the first driving wheel 11, the first driving rod 12, the second driving wheel 21 and the driving rod 23, so that the lock lever 50 moves up and down to realize locking or unlocking.

Specifically, in the embodiment of the present specification, the second transmission rod 22 passes through the center of the second transmission wheel 21, and the second transmission rod 22 is parallel to the driving rod 23.

Further, as shown in fig. 4, a second meshing tooth 211 is provided on an outer side surface of the second transmission wheel 21, and the second meshing tooth 211 is meshed with the first transmission rod 12 for transmission. And the second engagement tooth 211 and the first transmission rod 12 are engaged to realize transmission, and the first transmission rod 12 and the first transmission wheel 11 rotate synchronously, so that as shown in fig. 6, when the output shaft 41 of the motor 40 rotates in a first direction (for example, clockwise direction) in a first period, the first transmission wheel 11 rotates in a second direction (for example, counterclockwise direction) and the second transmission wheel 21 drives the driving rod 23 to rotate clockwise, so as to drive the lock lever 50 to move downwards to realize locking; when the output shaft 41 rotates counterclockwise in the second period, as shown in fig. 7, the first driving wheel 11 rotates clockwise, so that the second driving wheel 21 drives the driving lever 23 to rotate counterclockwise, and further drives the locking lever 50 to move upward for unlocking.

That is, the rotation direction of the second transmission wheel 21 is consistent with the rotation direction of the output shaft 41 of the motor 40, and further the locking or unlocking of the lock lever 50 can be controlled by the forward rotation or the reverse rotation of the motor 40, so that the control logic is simpler and clearer.

Moreover, by setting the number of teeth and the turning radius of the first transmission rod 12 rotating for one circle and setting the number of teeth and the turning radius of the second meshing teeth 211 on the outer peripheral surface of the second transmission wheel 21, the constant transmission ratio of the second transmission structure 20 relative to the first transmission structure 10 can be obtained, and the transmission stability and reliability are ensured to be high.

In the embodiment of the present specification, the transmission ratio of the first transmission rod 12 to the second transmission wheel 21 is greater than 1, and the rotation radius of the first transmission rod 12 is smaller than the rotation radius of the second transmission wheel 21. I.e. the second transmission wheel 21 is also a reduction gear, so that the rotational speed output by the motor 40 will be further reduced by the second transmission wheel 21.

Further, the second driving wheel 21 comprises a working part provided with a second meshing tooth 211 on the outer side surface and a connecting part which is not provided with the second meshing tooth 211 on the outer side surface, and the second meshing tooth 211 is meshed with the first driving rod 12 for driving; the connecting portion is used to connect the driving rod 23. That is, the outer side surface of the working part is provided with a second meshing tooth 211, and the second meshing tooth 211 is meshed with the first transmission rod 12 for transmission; the connecting portion is used to connect the driving rod 23. Namely, the second transmission wheel 21 can have a circular contour or a similar circular contour (as shown in fig. 6 and 7), a part of the circumference of the second transmission wheel 21 is provided with second meshing teeth 211, and a sector area occupied by the part of the circumference is a working part; the other part of the circumference of the second transmission wheel 21, which is not provided with the second meshing tooth 211, is used for connecting the driving rod 23, and the sector area occupied by the other part of the circumference is the connecting part.

In some preferred embodiments, as shown in fig. 4, the connection between the connection portion and the driving rod 23 is in a straight line transition with two end points of the connection portion. When the second transmission wheel 21 is in a complete circle shape, the second transmission wheel can work normally, but in actual use, the second transmission wheel 21 does not need to rotate for a complete circle, and only needs to rotate for a certain angle, namely, only the second meshing tooth 211 needs to be arranged on the working part, and the connecting part does not need to be provided with the second meshing tooth 211 and does not need to form a complete circle with the working part, so that the volume of the connecting part can be reduced, as shown in fig. 4, necessary areas with the driving rod 23 are reserved, the size of the working part can be greatly reduced through the design, and the material cost is saved.

It should be noted that the distance between the second engagement tooth 211 and the second transmission rod 22 and the distance between the driving rod 23 and the second transmission rod 22 may be equal or different, and the magnitude relationship between the two may be set according to the force required for actually driving the lock lever 50 to move up and down.

After the speed reduction is performed step by the first transmission structure 10 and the second transmission structure 20, when the output shaft 41 rotates clockwise for N turns in the first period, the second transmission wheel 21 only needs to rotate clockwise by the central angle corresponding to the second meshing tooth 211; the output shaft 41 rotates counterclockwise by N revolutions in the second period, and rotates counterclockwise by the central angle corresponding to the second meshing tooth 211 in correspondence with the second transmission wheel 21. That is, the ratio occupied by the working portion on the second transmission wheel 21 is determined according to the actual rotation speed of the motor 40, the transmission ratio between the motor 40 and the first transmission structure 10, and the transmission ratio between the first transmission structure 10 and the second transmission structure 20. Through the arrangement of the rotating speed of the motor 40 and the transmission ratio of the two-stage speed reducing structure, the second meshing teeth 211 do not need to be arranged on the outer peripheral surface of the connecting part, and therefore the process and the material cost are saved.

It should be noted that the size of the working portion, i.e. the number of the second meshing teeth 211, should be sufficient to consider the transmission error between the first transmission rod 12 and the working portion, so as to prevent the second transmission wheel 21 from falling out of the area covered by the second meshing teeth 211 when rotating along with the first transmission rod 12.

In the embodiment, since the working portion is a sector corresponding to the second engaging tooth 211, the magnetic device 30 can be embedded in the working portion, i.e. the magnetic device 30 is located between the second engaging tooth 211 and the second transmission rod 22. So that the magnetic device 30 changes its position relative to the position detecting structure 60 in response to the forward rotation or reverse rotation of the motor 40.

In some preferred embodiments, the magnetic device 30 is in the shape of a sector of a ring. The fan-shaped magnetic device 30 is matched with the shape of the working part, so that the limited space is fully utilized; meanwhile, under the condition of the same volume, the magnetic field intensity excited by the bar-shaped magnetic device 30 is larger, which is beneficial to the detection of the position detection structure 60.

In another embodiment of the present disclosure, the position detecting structure 60 may be embedded in the working portion, i.e., the position detecting structure 60 is located between the second meshing teeth 211 and the second transmission rod 22. So that the position detecting structure 60 is changed in position relative to the magnetic device 30 in response to the forward rotation or reverse rotation of the motor 40.

In some preferred embodiments, the position sensing structure 60 is in the shape of a fan ring.

In some optional embodiments, in order to prevent the magnetic device 30 or the position detecting structure 60 disposed on the second driving wheel 21 from falling off when the second driving wheel 21 rotates, a sealing cover may be disposed at the working portion of the second driving wheel 21, and the magnetic device 30 or the position detecting structure 60 may be fixed in the working portion by an adhesive manner or a slot connection manner, so as to ensure the stability of the connection between the magnetic device 30 or the position detecting structure 60 and the second driving wheel 21.

It should be noted that in the embodiment of the present disclosure, the transmission structure includes the first transmission structure 10 and the second transmission structure 20 to implement two-stage speed reduction, and in some other possible embodiments, the transmission structure may further include a plurality of speed reduction structures of other orders to implement more-stage speed reduction, and then the corresponding relationship between the movement direction of the lock lever 50 and the rotation direction of the motor output shaft 41 needs to be determined according to the specific number of the speed reduction structures.

Further, as shown in fig. 1, in the embodiment of the present disclosure, the second transmission wheel 21 and the housing of the motor 40 are located on the same side of the first transmission wheel 11, and the lock lever 50 is located on a side of the second transmission wheel 21 away from the first transmission wheel 11, so that the layout of the components can be more compact, which is beneficial to reducing the space occupied by the electronic lock, and facilitating to arrange the electronic lock in a limited space of a vehicle or on a charging gun.

Of course, other layouts of the above components may be provided, for example, the second transmission wheel 21 is disposed on the side of the first transmission wheel 11 away from the housing of the motor 40, and the lock lever 50 is disposed on the side of the second transmission wheel 21 away from the first transmission wheel 11.

As shown in fig. 5, the locking lever 50 is provided with a groove 51 matching with the driving lever 23, and the driving lever 23 matches with the groove 51 to realize the locking or unlocking action of the locking lever, and the working principle is shown in fig. 6 and 7, which are not described again here.

The locking rod 50 is further provided with a limiting structure 70. As shown in fig. 6 and 7, when the driving lever 23 rotates clockwise along with the second transmission wheel 21, the driving lever 23 not only provides a downward component force to the lock lever 50 to achieve locking, but also provides a horizontal component force to the lock lever 50, so that a limiting structure 70 is required to prevent the lock lever 50 from moving in a direction different from the locking or unlocking motion, i.e., the limiting structure 70 is used to limit the horizontal movement of the lock lever 50. The position limiting structure 70 also functions to limit the moving direction of the lock lever 50 when the driving lever 23 rotates counterclockwise with the second transmission wheel 21.

In one embodiment of the present disclosure, the magnetic device 30 is preferably a magnet and the position detecting structure 60 is a magnetic field sensor.

In other embodiments, the magnetic device 30 is a magnetic field sensor and the position sensing structure 60 is a magnet.

Further, the magnetic field sensor is a hall sensor. The magnet is a permanent magnet.

When the magnetic device 30 is a magnet, the position detecting structure 60 is a magnetic field sensor, and the magnet moves along with the second transmission structure 20, and the magnetic field sensor records continuous position change information each time the magnet rotates close to or away from the magnetic field sensor.

When the magnetic device 30 is a magnetic field sensor, the position detecting structure 60 is a magnet, the magnetic field sensor moves along with the second transmission structure 20, and the magnetic field sensor records continuous position change information each time the magnetic field sensor approaches or leaves the magnet.

The motor 40, the transmission structure, the magnetic device 30, the lock rod 50 and the position detection structure 60 are all arranged in the shell, and the magnetic device 30 or the position detection structure 60 is fixedly connected with the shell to ensure that the change of the detected induced current is more accurate. The limiting structure 70 may also be disposed inside the housing and connected to the housing, specifically, may be concentrically connected to the locking hole on the housing, so as to ensure that the locking lever 50 moves along a straight line.

In the electronic lock provided by the embodiment of the present disclosure, the relative position change of the magnetic device 30 or the position detecting structure 60 corresponds to the position change of the lock bar 50, and the relative position change of the magnetic device 30 and the position detecting structure 60 and the induced current detected by the position detecting structure 60 also change accordingly, so that the lock bar 50 is positioned according to the magnitude of the induced current, and the electronic lock is convenient and accurate. Furthermore, the relative position change between the magnetic device 30 and the position detecting structure 60 is continuous, and the linear movement of the lock rod 50 when it is lifted to be locked or unlocked is also continuous, so that the electronic lock provided in the embodiments of the present specification can detect not only whether the lock rod 50 is located at the locking position or the unlocking position, but also the position state of the lock rod 50 between the locking position and the unlocking position, thereby realizing the continuous detection of the position of the lock rod 50.

The embodiment of the specification further provides a vehicle, and the electronic lock is installed in the charging socket of the battery on the vehicle, and can guarantee that the charging gun is locked with the power receiving socket of the battery on the vehicle when charging, so that electric shock danger caused by falling of the charging gun is avoided.

It should also be understood that, in the embodiments herein, the term "and/or" is only one kind of association relation describing an associated object, and means that there may be three kinds of relations. For example, a and/or B, may represent: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" herein generally indicates that the former and latter related objects are in an "or" relationship.
