Referring to fig. 1, a first aspect of the present disclosure provides a charging stand 100 including a charging stand body 1, a base plate 2, a controller (not shown), and a driver 3, wherein the driver 3 includes a connection member 31, a driving wheel 32, and a motor (not shown). The controller may be disposed at any position of the charging stand 100, for example, the controller may be disposed inside the charging stand body 1, or the controller may be disposed on the floor 2, specifically, may be designed as needed, which is not limited in the present disclosure. The charging stand body 1 is positioned above the base plate 2 in the third direction Z, and is stacked on the base plate 2. The connection member 31 is connected with one side of the charging stand body 1 toward the bottom plate 2, the driving wheel 32 is connected to the connection member 31, the motor is electrically connected with the controller, and the output shaft of the motor is connected with the driving wheel 32. In this way, when the device to be charged matched with the charging stand 100 moves to the vicinity of the charging stand 100, the controller can generate a driving signal according to the charging stand 100 and the relative position signal between the device to be charged, and the motor of the driver 3 can drive the driving wheel 32 to rotate according to the driving signal after receiving the driving signal. Since the charging seat body 1 is connected with the driver 3, when the driving wheel 32 rotates to enable the driver 3 to translate on the bottom plate 2, the charging seat body 1 can move along with the driver 3, the charging seat realizes the adjusting position of the charging seat body 1, and the alignment between the charging seat body 1 and the equipment to be charged is realized.

Through such setting, charging seat 100 can independently align with waiting to charge equipment, is favorable to charging and accomodating waiting to charge equipment charging seat near to get back to charging seat 100, and the in-process of aiming at the charging seat need not manual operation, is favorable to further promoting the automation and the intellectuality of charging seat 100. The alignment between the charging seat main body 1 and the device to be charged can be understood as that the charging contact of the charging seat main body 1 is conducted with the charging contact of the device to be charged, or the charging contact of the charging seat main body 1 is aligned with and spaced from the charging contact of the device to be charged, and then the conduction between the charging contacts can be realized by controlling the device to be charged to execute a moving action, a tilting action or other actions; or, the storage cavity of the charging seat main body 1 is aligned to the equipment to be charged, and then the equipment to be charged can be stored by controlling the equipment to be charged to execute a moving action, a tilting action or other actions.

In other embodiments, the opening of the housing 11 may be far from the bottom plate 2, or the opening of the housing 11 may be provided on the side surface of the charging stand body 1, which is not limited by the present disclosure.

In some embodiments, the charging contacts of the charging stand 100 may be a first charging structure such as an electrical contact, and the charging contacts of the device to be charged may be a second charging structure such as a metal sheet. Through making charging seat 100 carry out position adjustment, be favorable to making the first charging structure of charging seat 100 fully contact with the second charging structure on the equipment that waits to charge, and then guarantee the effect of charging of treating the equipment that charges. Indeed, it is also possible that the first charging structure is provided as a metal sheet and the second charging structure is provided as an electrical contact, which is not limiting of the present disclosure.

In other embodiments, the charging contacts of the charging stand 100 may be provided with a first wireless charging power module, and the charging contacts of the device to be charged may be provided with a second wireless charging power module, so that charging between the charging stand 100 and the device to be charged can be performed through, for example, electromagnetic induction phenomenon, without enabling the current on the charging stand 100 to flow into the device to be charged through physical contact between conductive materials. In this way, it is possible to avoid that it is difficult to achieve good physical contact between the charging structures due to a positional error between the charging stand 100 and the device to be charged, or that it is difficult to achieve good physical contact between the charging stand 100 and the device to be charged due to dust or rust or the like existing between the charging structures after a long period of use.

In order to obtain a positional deviation between the device to be charged and the cradle 100, in some embodiments the cradle body 1 comprises a position identification 15, the device to be charged being provided with identification means and a detector. When the equipment to be charged returns to the vicinity of the charging seat 100, the recognition device scans the position recognition mark 15, the detector can acquire the position difference between the equipment to be charged and the charging seat main body 1 according to the position data of the position recognition mark 15, the controller sends the relative position signal to the charging seat 100 after generating the relative position signal, the controller sends a driving signal indicating the movement direction and the movement distance to the motor of the driver 3, and the motor drives the driving wheel 32 to rotate according to the driving signal, so that the charging seat 100 is driven to move to a desired position, and the alignment of the equipment to be charged and the charging seat 100 is realized. In other embodiments, the charging stand body 1 may be provided with an identification device, where the device to be charged is provided with a position identification mark 15, and the identification device may scan the position identification mark 15 on the device to be charged when the device to be charged returns to the vicinity of the charging stand 100, so as to obtain the relative position signal, which is not limited in the present disclosure. In still other embodiments, it is also possible that the charging stand body 1 is provided with both the position identification mark 15 and the identification means, and the device to be charged is provided with the identification means and the position identification mark 15, respectively.

In some embodiments, the location identification 15 comprises a two-dimensional code. In other embodiments, however, the location identification 15 may be any pattern that facilitates the detector to determine location information, and the present disclosure is not limited.

In some embodiments, the charging stand 100 may be provided with a scanning device, and the scanning device may scan a spatial layout in a near field range to obtain a position of the device to be charged, so that the charging stand 100 may obtain a relative position signal between the charging stand 100 and the device to be charged according to the position signal of the charging stand and the obtained position signal of the device to be charged; or, a scanning device may be provided for the device to be charged, and the scanning device may scan the spatial layout in the near field range to obtain the position of the charging stand, so that the device to be charged may obtain the relative position signal between the charging stand 100 and the device to be charged according to the position signal of the device to be charged and the obtained position signal of the device to be charged, and send the relative position signal to the charging stand.

It should be understood that the position identifying mark 15 is shown in the drawings as being disposed on the surface of the charging stand body 1 away from the base plate 2, but this is to be taken as an example and not limiting, and the position identifying mark 15 may be disposed on any surface of the charging stand body 1, for example, on any side surface, as long as the surface can be opposite to a certain position of the device to be charged, and the present disclosure is not limited. Similarly, the camera position can also be connected to any surface of the charging stand body 1, which is not described in detail in this disclosure.

The to-be-charged equipment and the charging seat 100 can be respectively provided with a communication module, so that communication connection between the to-be-charged equipment and the charging seat 100 is realized, and relative position signals generated by the detector of the to-be-charged equipment can be sent to the controller of the charging seat 100, so that translation of the charging seat main body 1 is realized. The communication modules can communicate through Bluetooth, WIFI and the like, so long as the mutual signal transmission between the equipment to be charged and the charging seat 100 can be realized, and the present disclosure is not limited.

In the embodiment shown in fig. 1, the driver 3 includes a driving wheel 32, where the driver 3 can translate the charging stand body 1 along a direction perpendicular to the rotation axis of the driving wheel 32, for example, along a first direction X, a second direction Y, or other directions perpendicular to the third direction Z. The driver 3 may be fixedly connected with the charging stand body 1. When there is only a positional deviation in a certain direction between the cradle 100 and the device to be charged, by this arrangement, the positional deviation in the direction of the cradle main body 1 and the device to be charged can be adjusted, a desired movement can be achieved with a minimum of structural parts, and production costs can be reduced.

For example, in some embodiments, when the device to be charged is close to the charging stand 100 and ready for alignment, the structure of the device to be charged is such that the device to be charged contacts both sides of the charging stand 100 in the second direction Y, which may be regarded as that the device to be charged "clamps" the charging stand 100 in the second direction Y, so that the positions of the charging stand 100 and the device to be charged in the second direction Y are fixed without performing position adjustment. However, since the cradle 100 and the device to be charged do not have structural contact in the first direction X, it is difficult to ensure whether the positions of the cradle 100 and the device to be charged in the first direction X are already aligned, and thus only the positional adjustment in the first direction X is required in this embodiment.

The base plate 2 may include a first guide rail 21, and the charging stand 100 includes a first guide 14 provided at a side of the charging stand body 1 facing the base plate 2, the first guide rail 21 extending in a direction perpendicular to the rotation axis direction of the driving wheel 32; the first guide 14 is engaged with the first rail 21. For example, when the position of the charging stand body 1 in the first direction X needs to be adjusted, the first guide rail 21 extends in the first direction X, which is perpendicular to the rotation axis direction of the driving wheel 32. By providing the first guide rail 21 and the first guide 14, the movement direction of the charging stand body 1 can be further restricted, and the change of the angle between the rotation axis of the driving wheel 32 and the movement direction after avoiding long-time use of the driver 3, which in turn causes the movement direction of the charging stand body 1 to be offset, makes it difficult for the charging stand body 1 to achieve good positional alignment with the device to be charged.

In some embodiments, the first guide rail 21 may be a groove recessed from the surface of the base plate 2 facing the cradle body 1, and the first guide 14 is a protrusion provided on the surface of the cradle body 1 facing the base plate 2, the protrusion being embedded in the groove such that the cradle body 1 can only move in the extending direction of the first guide rail 21. The person skilled in the art can reduce the friction between the protrusions and the grooves by applying a lubricant between the first rail 21 and the first guide 14, thereby avoiding fatigue wear of the contact surfaces of the first rail 21 and the first guide 14 to some extent.

In other embodiments, the first guide rail 21 protrudes from the bottom plate 2 toward the charging stand body 1, and the first guide 14 includes a first driven wheel and a second driven wheel, the first driven wheel is disposed on one side of the first guide rail 21, the second driven wheel is disposed on the other side of the first guide rail 21, and rotation axes of the first driven wheel and the second driven wheel are perpendicular to an extending direction of the first guide rail 21. When the charging seat main body 1 translates, the first driven wheel and the second driven wheel roll on the surface of the bottom plate 2, so that friction between the charging seat main body 1 and the bottom plate 2 in the translation process can be reduced.

In the embodiment shown in fig. 1, the base plate 2 is provided with four first guide rails 21 extending in the first direction X, but this should be taken as an example and not as a limitation, and a person skilled in the art may design other numbers of first guide rails 21 as desired, and the first guide rails 21 may extend in other directions as well, and the present disclosure is not limited thereto.

In embodiments where the base plate 2 is not provided with the first guide rail 21, the charging seat body 1 may also include a driven wheel, so that the charging seat body 1 can be supported to a certain extent, avoiding the weight of the entire charging seat body 1 being borne by the driver 3, which is beneficial for prolonging the service life of the driver 3.

Referring to fig. 2, in other embodiments, the connection member 31 includes a connection post rotatably connected with the charging stand body 1; the driving wheel 32 includes a first driving wheel 321 and a second driving wheel 322, and the rotation axis of the first driving wheel 321 and the rotation axis of the second driving wheel 322 are collinear and perpendicular to the central axis of the connection post, respectively. The first driving wheel 321 and the second driving wheel 322 are respectively connected to connection posts between the first driving wheel 321 and the second driving wheel 322. The motors include a first motor (not shown) connected with the first driving wheel 321 and a second motor (not shown) connected with the second driving wheel 322 such that the first motor and the second motor can control the first driving wheel 321 and the second driving wheel 322, respectively, thereby enabling the first driving wheel 321 and the second driving wheel 322 to operate with different parameters, respectively: in the view angle in the third direction Z, when the first driving wheel 321 and the second driving wheel 322 are rotated in the same direction at the same speed, the cradle body 1 is translated with the driver 3; when the first driving wheel 321 and the second driving wheel 322 are reversely rotated at the same speed, the driver 3 rotates around the central axis of the connection post. In this way, the driver 3 can adjust the movement direction of the charging stand body 1 by rotating around the central axis of the connection post, and then drive the charging stand body 1 to move by rotating the first driving wheel 321 and the second driving wheel 322 in the same speed and the same direction, so that the charging stand body 1 can be moved in more directions, and the position adjustment of the charging stand 100 is more flexible.

It will be appreciated that one skilled in the art may design the relationship between the output shaft axis of the first motor and the output shaft axis of the second motor based on the arrangement of the transmission between the first drive wheel 321 and the first motor and the arrangement of the transmission between the second drive wheel 322 and the second motor, e.g., the output shaft axis of the first motor may be collinear with the output shaft axis of the second motor, or may be non-collinear, without limitation of the present disclosure.

As shown in fig. 2, in some embodiments, the charging stand body 1 includes a connection groove 13, the connection groove 13 is disposed at a side of the charging stand body 1 facing the base plate 2, and the connection post is rotatably connected in the connection groove 13. One skilled in the art can apply a lubricant in the connecting groove 13, which is beneficial to reducing friction between the connecting post and the connecting groove 13 and avoiding fatigue wear on the contact surface of the connecting post and the connecting groove 13.

In other embodiments, it is also possible that the charging seat body 1 is provided with an orifice on the side facing the bottom plate 2, the connection post is provided in the orifice, and the lubricant is applied on the contact surface of the orifice and the connection post. Alternatively, a bearing may be provided in the connecting groove 13 or the orifice, and the outer ring of the bearing may be in contact with the wall surface of the connecting groove 13 or the orifice, and the inner ring of the bearing may be in contact with the surface of the connecting post, which is not limited in this disclosure.

In order to enable the first driving wheel 321 and the second driving wheel 322 to maintain enough friction with the surface of the base plate 2, so as to drive the charging seat main body 1 to move, and avoid slipping, the first driving wheel 321 and the second driving wheel 322 should be pressed against the surface of the base plate 2. In some embodiments, it may be that the bottom wall of the connecting groove 13 contacts the end surface of the connecting post, so that a part of the weight of the charging seat body 1 is applied to the driver 3, which is advantageous for the first driving wheel 321 and the second driving wheel 322 to remain pressed against the surface of the base plate 2. However, due to processing errors, it is difficult to ensure parallelism between the bottom wall of the connecting groove 13 and the end face of the connecting column, so that different areas of the end face of the connecting column are unevenly stressed, and areas with larger stress are more prone to stress fatigue; in order to ensure the machining accuracy of the bottom wall of the connecting groove 13 and the end face of the connecting post, the machining cost increases. Thus, in some embodiments, the charging stand 100 may further include an elastic member 4, where the elastic member 4 is disposed in the connection groove 13, and one end of the elastic member 4 abuts against the bottom wall of the connection groove 13, and the other end abuts against the end face of the connection post. The elastic member 4 is kept in a compressed state, so that a force directed from the charging seat body 1 to the bottom plate 2 is applied to the driver 3 at the end face of the connecting post, so that the first driving wheel 321 and the second driving wheel 322 can maintain enough friction with the surface of the bottom plate 2, which is beneficial to the first driving wheel 321 and the second driving wheel 322 to drive the charging seat body 1 to move when rotating, and the slipping phenomenon is avoided.

It should be understood that the elastic member 4 shown in fig. 2 is a spring, but this is to be taken as an example and not a limitation, and the elastic member 4 may also be a member capable of elastic compression such as a spring washer, etc., and the present disclosure is not limited thereto.

Similar to the above description of the embodiment shown in fig. 1, the base plate 2 may include a first guide rail 21, and the cradle 100 includes a first guide 14 provided at a side of the cradle body 1 facing the base plate 2, the first guide rail 21 extending in a direction perpendicular to the rotational axis directions of the first driving wheel 321 and the second driving wheel 322; the first guide 14 cooperates with the first guide rail 21, and will not be described here. In this embodiment, the cradle body 1 is movable only in the extending direction of the first rail 21. However, after the driver 3 is used for a long time, the rotation axes of the first driving wheel 321 and the second driving wheel 322 may deviate from the preset rotation axis direction, which may be understood as a direction perpendicular to the extending direction of the first rail 21, and at this time, an included angle exists between the movement direction of the driver 3 and the extending direction of the first rail 21, which further results in extrusion between the first guide 14 and the first rail 21, so that a larger driving force needs to be generated when the driver 3 is to keep moving at the same speed, which further affects the service life of the driver 3. When the offset occurs, this embodiment is capable of rotating the driver 3 by the same-speed reverse rotation of the first driving wheel 321 and the second driving wheel 322 until the rotation axes of the first driving wheel 321 and the second driving wheel 322 are parallel to the preset rotation axis, thereby enabling the driver 3 to translate along the extending direction of the first rail 21 without disassembling and repairing the entire cradle 100.

Or as shown in fig. 2, in some embodiments, the cradle 100 further comprises an intermediate plate 5, a second guide 53 and a third guide 16. The intermediate plate 5 is disposed between the bottom plate 2 and the charging stand body 1. The intermediate plate 5 comprises a hollowed out area 52, and the driver 3 is arranged through the hollowed out area 52, so that the driver 3 can pass through the intermediate plate 5 to be in contact with the bottom plate 2. The second guide 53 is disposed on a side of the middle plate 5 facing the bottom plate 2, and the bottom plate 2 is provided with a second guide rail 22, and the second guide 53 is engaged with the second guide rail 22. The third guide 16 is disposed on a side of the charging stand body 1 facing the middle plate 5, and the middle plate 5 includes a third guide rail 51, and the third guide 16 is engaged with the third guide rail 51. The second guide rail 22 and the third guide rail 51 may have different extending directions, for example, the second guide rail 22 may extend in the first direction X, and the third guide rail 51 may extend in the second direction Y; or the second rail 22 and the third rail 51, is not limited by the present disclosure.

The second guide rail 22 and the second guide 53 are arranged so that the intermediate plate 5 and the bottom plate 2 can perform relative movement only in the extending direction of the second guide rail 22, and the third guide rail 51 and the third guide 16 are arranged so that the intermediate plate 5 and the charging stand main body 1 can move only in the extending direction of the third guide rail 51. Taking the embodiment shown in fig. 2 as an example, the second guide rail 22 extends along the second direction Y, the third guide rail 51 extends along the first direction X, the middle plate 5 can only move relative to the bottom plate 2 along the second direction Y, and the charging stand body 1 can only move relative to the middle plate 5 along the first direction X. When it is necessary to adjust the position of the cradle body 1 in the first direction X: the first driving wheel 321 and the second driving wheel 322 are rotated in opposite directions at the same speed, so that the driver 3 is rotated to a direction of movement parallel to the first direction X, and then the first driving wheel 321 and the second driving wheel 322 are rotated in the same direction at the same speed, and the cradle body 1 and the intermediate plate 5 are relatively moved in the first direction X, thereby adjusting the position of the cradle body 1 in the first direction X while the base plate 2 and the intermediate plate 5 remain relatively stationary. When it is desired to adjust the position of the cradle body 1 in the second direction Y, the first driving wheel 321 and the second driving wheel 322 are rotated in opposite directions at the same speed, so that the driver 3 is rotated to a direction of movement parallel to the second direction Y, and then the first driving wheel 321 and the second driving wheel 322 are rotated in the same direction at the same speed, the cradle body 1 is moved in the second direction Y, and since the intermediate plate 5 and the cradle body 1 can only move relatively in the first direction X, the cradle body 1 will drive the intermediate plate 5 to move together in the second direction Y, i.e., at this time the intermediate plate 5 and the cradle body 1 remain relatively stationary, and the intermediate plate 5 and the cradle body 1 move relatively to the base plate 2. Especially when the extending direction of the second rail 22 and the third rail 51 is perpendicular, the relative movement between the intermediate plate 5 and the bottom plate 2 and the relative movement between the intermediate plate 5 and the charging stand body 1 are independent of each other, and when the intermediate plate 5 and the bottom plate 2 are relatively moved along the extending direction of the second rail 22, the intermediate plate 5 and the charging stand body 1 can be kept relatively stationary. In the embodiment in which the extending directions of the second rail 22 and the third rail 51 are not perpendicular, the charging stand body 1 and the intermediate plate 5 will also perform the relative movement when the intermediate plate 5 moves along the second rail 22 and the bottom plate 2, so even if only the position of the charging stand body 1 in the extending direction of the second rail 22 is adjusted, the position of the charging stand body 1 in the extending direction of the third rail 51 needs to be adjusted to keep the charging stand body 1 and the intermediate plate 5 at the same relative rest position. Therefore, the extending directions of the second guide rail 22 and the third guide rail 51 are set to be vertical, so that the position adjustment program can be simplified, the calculation amount of the controller can be reduced, the requirement on the performance of the controller can be further reduced, and the cost can be saved.

As described above for the first rail 21 and the first guide 14, in some embodiments, it may be that the second rail 22 comprises a groove and the second guide 53 comprises a protrusion; the third guide rail 51 includes a groove and the third guide 16 includes a protrusion. Alternatively, in other embodiments, the second guide rail 22 may protrude from the bottom plate 2 toward the middle plate 5, and the second guide 53 may include a third driven wheel and a fourth driven wheel, where the third driven wheel is disposed on one side of the second guide rail 22, and the fourth driven wheel is disposed on the other side of the second guide rail 22; the third guide rail 51 protrudes from the intermediate plate 5 toward the charging stand body 1, and the third guide 16 includes a fifth driven wheel and a sixth driven wheel, the fifth driven wheel being disposed at one side of the third guide rail 51, and the fifth driven wheel being disposed at the other side of the second guide rail 22.

It will be appreciated that it is also possible that the second guide rail 22 comprises a groove and the second guide 53 comprises a protrusion; the third guide rail 51 protrudes from the intermediate plate 5 toward the charging stand body 1, and the third guide 16 includes a fifth driven wheel and a sixth driven wheel. Alternatively, it is also possible that the second guide rail 22 protrudes from the bottom plate 2 towards the intermediate plate 5, the second guide 53 comprising a third driven wheel and a fourth driven wheel; the third guide rail 51 includes a groove and the third guide 16 includes a protrusion. The present disclosure is not limited in this regard.

Indeed, in other embodiments, it is also possible that the driver 3 rotates to a direction of movement towards the desired position, and the driver 3 moves directly to the desired position, at which time the movement of the driver 3 simultaneously moves the charging stand body 1 and the intermediate plate 5, which is not a limitation of the present disclosure.

In the embodiment in which the second guide rail 22 and the third guide rail 51 are not provided, as the service time of the cradle 100 increases, the reference direction of the rotation axis of the first driving wheel 321 or the second driving wheel 322 may be deviated from the preset zero direction, and thus it is difficult to ensure that the driver 3 rotates to a desired advancing direction when the driver 3 rotates. Deviations in the advancing direction will cause the charging stand body 1 to be difficult to move to a desired position even if the driver 3 moves a desired distance. By providing the first rail 21 and the second rail 22, the charging stand body 1 can be moved in two predetermined directions, and by moving the intermediate plate 5 a desired distance with respect to the bottom plate 2 and moving the charging stand body 1 a desired distance with respect to the intermediate plate 5, the charging stand body 1 can reach a desired position.

In some embodiments, the length of extension of the hollowed out area 52 in the extension direction of the third guide rail 51 is greater than or equal to the maximum length of extension of the third guide rail 51, so that the driver 3 can have enough travel in the hollowed out area 52 to achieve the relative movement of the charging stand body 1 and the intermediate plate 5. The hollow area 52 may be provided at a position on the intermediate plate 5 where the third guide rail 51 is not provided, so that the arrangement area of the hollow area 52 is increased as much as possible, which is advantageous in reducing the weight of the intermediate plate 5, thereby reducing the overall weight of the charging stand 100, and also enabling the driver 3 to have a sufficient movement stroke within the hollow area 52.

A second aspect of the present disclosure provides a device assembly comprising a device to be charged and a charging stand 100 as in any of the previous embodiments. For example, the device assembly may include a robot assembly, the charging dock 100 may be a robotic charging dock, and the device to be charged may be a robot, which may include robots configured with different functions, such as a robot dog, a sweeping robot, a service robot, and the like.

The specific embodiments described herein are offered by way of example only to illustrate the spirit of the present disclosure. Those skilled in the art to which this disclosure pertains may make numerous modifications, additions, or substitutions to the described embodiments and those alternatives may be made without departing from the spirit of the disclosure or exceeding the scope of the disclosure as defined in the accompanying claims.

The technical features of the above embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.
