Detailed Description

In order to make the objects, technical solutions and advantages of the present application more clear, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.

When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus consistent with certain aspects of the present application, as detailed in the appended claims.

In a first aspect, the present embodiment provides a foldable screen assembly 100, and referring to fig. 3 and 4, the foldable screen assembly 100 includes a display screen 120 and a driving structure 140.

The display screen 120 may be a component used only to display information. Of course, the display screen 120 may also be a component capable of sensing touch operation, since the display device 10 generally has a touch function in combination with the present invention. The size of the display screen 120 in the related art is generally fixed, and the display area is also fixed, which cannot meet the use requirements of users in different scenes. Based on this, referring to fig. 3 to 9, in the embodiment of the present application, the display screen 120 is disposed to include the fixing portion 122 and the extending portion 124 connected to the fixing portion 122, so that the display area of the display screen 120 may correspond to the display area of the first display surface 1222 of the fixing portion 122, or the sum of the display areas of the first display surface 1222 of the fixing portion 122 and the second display surface 1242 of the extending portion 124.

The fixing portion 122 and the extending portion 124 may be independent display components, and the display screen 120 is formed by connecting the fixing portion 122 and the extending portion 124. Of course, in order to prevent a connection trace such as an adhesive between the fixed portion 122 and the extending portion 124 when the display area of the display panel 120 corresponds to the sum of the display areas of the first display surface 1222 and the second display surface 1242, the fixed portion 122 and the extending portion 124 may be integrally formed, and a portion of the display panel 120 that remains unchanged during adjustment is defined as the fixed portion 122, and a portion of the display panel 120 that varies during adjustment is defined as the extending portion 124.

To enable the display area of the display screen 120 to be adjusted from the display area corresponding to the first display surface 1222 to the sum of the display areas corresponding to the first display surface 1222 and the second display surface 1242, this may be accomplished by the driving structure 140. Specifically, when the display area of the display screen 120 corresponds to the display area of the first display surface 1222, the extending portion 124 may be located on one side of the first back surface 1224 of the fixing portion 122, as can be seen in fig. 3, 4, 5, 6 and 8. The first back surface 1224 is a surface of the fixing portion 122 opposite to the first display surface 1222. The driving structure 140 may be located on one side of the first back surface 1224 of the fixing portion 122 and connected to the extending portion 124. When the display area of the display screen 120 needs to be adjusted from the display area corresponding to the first display surface 1222 to the sum of the display areas corresponding to the first display surface 1222 and the second display surface 1242, the driving structure 140 can be adjusted to drive the extension portion 124 to move, so that the second display surface 1242 of the extension portion 124 and the first display surface 1222 of the fixing portion 122 are located on the same plane, as shown in fig. 7.

The drive structure 140 and the extension 124 may be connected in any manner. For example, the driving structure 140 and the extension 124 may be connected by a clamping member or an adhesive. The following description describes in detail a case where the driving structure 140 and the extending portion 124 are connected by a clamping member, the clamping member may include a substrate, and a first clamping plate and a second clamping plate that are disposed opposite to each other, the substrate has a second carrying surface, the first clamping plate and the second clamping plate are both connected to the second carrying surface, and are disposed in a direction approaching to each other from the second carrying surface, so that a clamping region is formed among the first clamping plate, the second clamping plate, and the second carrying surface, and the driving structure 140 and the extending portion 124 are both clamped in the clamping region. Of course, to reduce the shielding of the second display surface 1242 by the clamping member, the clamping member may be located at an end of the extension portion 124. Specifically, the clamping member may be located at an end of the extending portion 124 away from the fixing portion 122, and an area of one clamping plate of the clamping member contacting the second display surface 1242 should be as small as possible to reduce the shielding of the second display surface 1242 by the clamping plate.

To prevent the driving structure 140 from shielding the second display surface 1242 after connecting with the extension portion 124, the driving structure 140 may be connected with the second back surface 1244 of the extension portion 124. The second back face 1244 is a surface of the extending portion 124 opposite to the second display face 1242. Specifically, the driving structure 140 and the second back face 1244 may be connected by an adhesive. To reduce the amount of adhesive used and reduce the cost, the area of the connecting region between the driving structure 140 and the second back surface 1244 should be as small as possible. For example, the second rear face 1244 has a trailing end 12442, and the drive structure 140 may be coupled only to the trailing end 12442. The pulling end 12442 is an end of the extending portion 124 away from the fixing portion 122.

The driving structure 140 may be any component having a telescopic function, and it is only necessary to adjust the extending portion 124 from the state of being located on the first back surface 1224 of the fixing portion 122 to the state of being located on the same plane as the first display surface 1222 and the second display surface 1242. For convenience of description, a state in which the extension portion 124 is located on the side of the first back surface 1224 of the fixing portion 122 is defined as a first state of the display screen 120, and a state in which the second display surface 1242 of the extension portion 124 and the first display surface 1222 of the fixing portion 122 are on the same plane is defined as a second state of the display screen 120. The adjustment of the display screen 120 from the first state to the second state can be achieved by either rotation or translation.

When the adjustment of the display screen 120 from the first state to the second state is realized by rotating, referring to fig. 11, the driving structure 140 may include a second driving member 142a, a first rotating rod 144a and a second rotating rod 146 a. The second driving member 142a is located on one side of the first back surface 1224 of the fixing portion 122. The boundary line between the fixing portion 122 and the extending portion 124 is a first boundary line M, and the first rotating rod 144a is located on one side of the first back surface 1224 of the fixing portion 122 and is parallel to the first boundary line M. The first rotating rod 144a is connected to the second driving member 142a, so as to be driven by the second driving member 142a to rotate around a straight line parallel to the first boundary line M as a rotating axis. The second rotating lever 146a is connected to the first rotating lever 144a and the extension portion 124 such that the second rotating lever 146a can rotate along with the first rotating lever 144a, and the second display surface 1242 of the extension portion 124 can be flush with the first display surface 1222.

To avoid wear of the display screen 120 caused by the rotation of the first rotating rod 144a, the driving structure 140 may further include a sleeve 148 a. The sleeve 148a is located at the first boundary line M and connected to the display screen 120, and the first rotating rod 144a may be embedded in the sleeve 148 a. To avoid the sleeve 148a being disposed to affect the connection of the first rotating rod 144a to the second driving member 142a and the connection of the first rotating rod 144a to the second rotating rod 146a, the sleeve 148a may be provided with an opening.

The second driving member 142a may drive the first rotating rod 144a to rotate in any manner. For example, the second driving member 142a drives the first rotating rod 144a to rotate by a belt transmission, a gear transmission, etc. When the second driving member 142a drives the first rotating rod 144a to rotate through belt transmission, the second driving member 142a may include a second motor, a driving wheel, a driven wheel and a belt. The driving wheel is sleeved on the output shaft of the second motor to rotate along with the output shaft of the second motor. The driven wheel is sleeved on the first rotating rod 144 a. The belt is sleeved on the driving wheel and the driven wheel, so that the driving wheel can drive the driven wheel and the first rotating rod 144a to rotate.

When the adjustment of the display screen 120 from the first state to the second state is realized as a translation, the driving structure 140 may include a telescopic member. The number of the telescopic pieces can be one or more. Referring to fig. 3, when the number of the telescopic members is one, the telescopic members are located at one side of the first back surface 1224 of the fixing portion 122 and connected with the extension portion 124; the extendable member is extendable in a third direction s such that the second display surface 1242 is in the same plane as the first display surface 1222. The third direction s is a direction pointing from a to B. A is the position of the connection point of the expansion piece and the extension part 124 when the display screen 120 is in the first state, and B is the position of the connection point of the expansion piece and the extension part 124 when the display screen 120 is in the second state. As can be seen from the above, the movement path of the telescopic member is a line segment that is not parallel to the first display surface 1222, so that the second display surface 1242 can smoothly move from the side of the first back surface 1224 of the fixing portion 122 to the same plane as the first display surface 1222, the extending portion 124 can be a flexible screen, and the telescopic member is connected to only the pulling end 12442 of the extending portion 124.

The number of the telescopic members may also be two, and referring to fig. 4, when the number of the driving structures 140 is two, the two telescopic members may be a first telescopic member 142c and a second telescopic member 144c, respectively, for the convenience of distinction. The first telescopic member 142c may be located on one side of the first back surface 1224 of the fixing portion 122 and parallel to the first display surface 1222. The second telescopic member 144c may be located on a side of the first telescopic member 142c away from the fixing portion 122 and perpendicular to the first display surface 1222, and the second telescopic member 144c is connected to the first telescopic member 142 c. The first expansion piece 142c can be expanded along the first direction p and the second expansion piece 144c can be expanded along the second direction r, so that the second display surface 1242 is in the same plane as the first display surface 1222. The first direction p is a direction parallel to the first display surface 1222 and pointing from the center of the fixing portion 122 to the center of the first boundary line M, and the second direction r is a direction perpendicular to the first display surface 1222 and pointing from the first back surface 1224 to the first display surface 1222. As can be seen from the above, the two telescopic members are configured to divide the movement path of one telescopic member into a direction perpendicular to the first display surface 1222 and a direction parallel to the first display surface 1222, so that the extending process of the extending portion 124 is more stable. The first boundary line M is a boundary line between the fixing portion 122 and the extending portion 124. In order to make the second display surface 1242 smoothly move from the side of the first back surface 1224 of the fixing portion 122 to the same plane as the first display surface 1222, the extending portion 124 may be a flexible screen, and the first telescopic member 142c is connected to the drawing end 12442 only.

The telescopic member may be any device having a telescopic function. For example, the telescoping member may be an electric push rod, a pneumatic cylinder, a hydraulic cylinder, a scissor lift, or the like. When the number of the telescopic members is two, the first telescopic member 142c may be an electric push rod, and the second telescopic member 144c may be a scissor lift.

When the display screen 120 is adjusted from the first state to the second state in a translational motion, referring to fig. 8 to 10, in addition to the above embodiments, the driving structure 140 may further include a first driving member 141d, a screw 142d, a slider 143d, a worm wheel 144d, and a worm 145 d. The first driving member 141d is disposed on one side of the first back surface 1224 of the fixing portion 122. The screw 142d is perpendicular to the first display surface 1222 and connected to the first driving member 141d, and the first driving member 141d can drive the screw 142d to rotate. The sliding block 143d has a first mounting hole 1431d perpendicular to the first display surface 1222, and the sliding block 143d is sleeved on the screw 142d through the first mounting hole 1431 d. The first installation hole 1431d includes a first connection section 14311d and a second connection section 14312d, and the first connection section 14311d is threadedly connected with the screw 142 d. The slider 143d also has a second mounting hole 1432d parallel to the first display surface 1222, and the second mounting hole 1432d communicates with the second connection section 14312 d. The worm gear 144d is located at the second connection section 14312d and is fixedly sleeved on the screw 142 d. The worm 145d is inserted into the second mounting hole 1432d and engaged with the worm wheel 144 d. The worm 145d is also connected to the pulling end 12442. When the first driving element 141d can drive the screw 142d to rotate, the slider 143d can move along the second direction r and the worm 145d can move along the first direction p under the driving of the screw 142d, so that the second display surface 1242 and the first display surface 1222 are in the same plane. The first direction p is a direction parallel to the first display surface 1222 and pointing from the center of the fixing portion 122 to the center of the first boundary line M. The second direction r is a direction perpendicular to the first display surface 1222 and directed from the first back surface 1224 to the first display surface 1222.

As can be seen from the above, the first driving element 141d, the screw 142d, the slider 143d, the worm wheel 144d and the worm 145d drive the extension portion 124 in a similar operation principle to the first expansion member 142c and the second expansion member 144c drive the extension portion 124, and each has a moving path along a direction perpendicular to the first display surface 1222 and a moving path along a direction parallel to the first display surface 1222. The first boundary line M is a boundary line between the fixing portion 122 and the extending portion 124. In order to make the second display surface 1242 smoothly move from the side of the first back surface 1224 of the fixing portion 122 to the same plane as the first display surface 1222, the extending portion 124 may be a flexible screen, and the first telescopic member 142c is connected to the drawing end 12442 only.

In order to enable the sliding block 143d to move along the second direction r without following the rotation of the screw 142d when the screw 142d rotates, the driving structure 140 may further include a limiting rod 146d perpendicular to the first display surface 1222. The sliding block 143d may further have a third mounting hole 1433d perpendicular to the first display surface 1222, and the limiting rod 146d is disposed through the third mounting hole 1433 d.

The first driving member 141d may include a first motor, and an output shaft of the first motor is connected to the screw 142d to rotate the screw 142 d. In addition, the first driving member 141d may also include a first motor and a belt transmission member, and the belt transmission member is connected to the output shaft of the first motor and the screw 142d, so that the first motor moves to drive the belt transmission member and the screw 142d to rotate. The belt drive may also be replaced by a gear drive.

When assembling the display device 10 formed by the foldable screen assembly 100, the driving structure 140 of the foldable screen assembly 100 may be directly connected to the backlight module of the display device 10. However, when the driving structure 140 is connected to the backlight module, it is necessary to note that the fixing portion 122 is not inclined, and the assembly is relatively complicated, in order to simplify the connection between the foldable screen assembly 100 and the backlight module of the display device 10 according to the embodiment of the present application, referring to fig. 5 to 7, the foldable screen assembly 100 may further include a second bottom plate 160. The second base plate 160 is located on a side of the driving structure 140 away from the fixing portion 122 and is parallel to the fixing portion 122, and the second base plate 160 is connected to the driving structure 140. By additionally arranging the second base plate 160 parallel to the fixing portion 122 and connecting the driving structure 140 with the second base plate 160, the surface of the second base plate 160 away from the driving structure 140 can be directly connected with the backlight module when the foldable screen assembly 100 is assembled with the backlight module, so that the assembly of the display device 10 is easier.

As will be described in detail below with reference to fig. 5 to 7, the second base plate 160 has a first bearing surface 162 facing the fixing portion 122. When the driving structure 140 includes the second driving member 142a, the first rotating rod 144a and the second rotating rod 146a as described above, in order to allow a sufficient gap between the fixing portion 122 and the second bottom plate 160 to enable the display screen 120 to be adjusted from the first state to the second state, referring to fig. 11, the driving structure 140 may further include a supporting rod 149a disposed on one side of the first back surface 1224 of the fixing portion 122, and two ends of the supporting rod 149a are respectively connected to the first back surface 1224 and the first supporting surface 162. In order to reduce the gap between the fixing portion 122 and the second bottom plate 160 after the display screen 120 is adjusted to the first state and the second state, so as to reduce the size of the display device 10, the supporting rod 149a may be an extendable rod.

To avoid damage to the folding screen assembly 100 during shipping, the folding screen assembly 100 may also include four second side panels 180, fig. 1, 2, 5, 6, and 7. Each second side plate 180 is located on one side of the first bearing surface 162 of the second bottom plate 160 and connected to the first bearing surface 162, so that the four second side plates 180 and the second bottom plate 160 together form an accommodating space N. When the extending portion 124 is located on one side of the first back surface 1224 of the fixing portion 122, both the extending portion 124 and the driving structure 140 can be located in the accommodating section N and the fixing portion 122 can be located at the port of the accommodating section N.

In order to prevent the second side plate 180 from being disposed to influence the adjustment of the display screen 120 from the first state to the second state, referring to fig. 6 and 7, the second side plate 180 near the first boundary line M of the four second side plates 180 may be rotatably connected to the second bottom plate 160. By disposing the second side plate 180 near the first boundary line M and the second bottom plate 160 in a rotatable connection, when the display screen 120 is changed from the first state to the second state, the second side plate 180 can be rotated to make the second side plate 180 parallel to the second bottom plate 160, so that the driving structure 140 can be smoothly unfolded. The second side plate 180 is rotatably connected to the second bottom plate 160 by a hinge or the like, which is not limited herein. Besides, in order to prevent the second side plate 180 from being disposed to influence the adjustment of the display screen 120 from the first state to the second state, referring to fig. 5, the second side plate 180 close to the first boundary line M among the four second side plates 180 may be further disposed as a retractable plate, so that the second side plate 180 can move along the fourth direction t. The fourth direction t is a direction from the first display surface 1222 to the first rear surface 1224.

When the driving structure 140 is implemented as described above, in order to simplify the connection between the foldable screen assembly 100 and the backlight module of the display device 10, the foldable screen assembly 100 further includes a second base plate 160. To simplify the structure of the folding screen assembly 100, referring to fig. 11 to 15, the driving structure 140 may further include a first bottom plate 141e and a first side plate 142 e. The first bottom plate 141e is located on one side of the first back face 1224 of the fixing portion 122, and the first side plate 142e is located between the fixing portion 122 and the first bottom plate 141 e. The boundary line between the fixing portion 122 and the extending portion 124 is a first boundary line M, and the first side plate 142e can be rotatably connected to the first bottom plate 141e corresponding to the edge of the first boundary line M. The extending portion 124 can be slidably connected to a side of the first side plate 142e away from the first bottom plate 141e and then disposed on a side of the first back 1224 of the fixing portion 122, so that the first side plate 142e and the first bottom plate 141e rotate relatively to drive the extending portion 124 to move, thereby realizing that the second display surface 1242 and the first display surface 1222 are in the same plane. At this time, the first bottom plate 141e and the first side plate 142e of the driving structure 140 can both adjust the display screen 120 from the first state to the second state, and directly connect the first bottom plate 141e with the backlight module, so that the structure of the foldable screen assembly 100 is simplified. Of course, in order to prevent the fixing portion 122 from tilting after the first bottom plate 141e is connected to the backlight module, the first bottom plate 141e is preferably parallel to the fixing portion 122.

In order to make the second display surface 1242 smoothly move from the side of the first back surface 1224 of the fixing portion 122 to the same plane as the first display surface 1222, the extending portion 124 may be a flexible screen.

The slidable connection of the first side plate 142e to the extension 124 may be achieved by rollers 143 e. Specifically, the fixing plate 144e may be disposed on the first side plate 142e, the roller 143e may be disposed on the fixing plate 144e, and the central axis of the roller 143e may be located at the first boundary line M, so that the extending portion 124 may be disposed on one side of the first back surface 1224 of the fixing portion 122 after bypassing the roller 143 e.

The roller 143e may be fixedly mounted to the fixing plate 144 e. If the roller 143e is fixedly mounted on the fixing plate 144e, when the display screen 120 is adjusted from the first state to the second state, the extending portion 124 and the roller 143e are in sliding friction, and in order to reduce the wear of the extending portion 124, the extending portion 124 and the roller 143e may be in rolling friction. Specifically, the roller 143e and the fixing plate 144e may be rotatably connected, so that the roller 143e may rotate around a straight line parallel to the first boundary line M as a rotation axis when the extending portion 124 is unfolded. The roller 143e is rotatably connected to the fixing plate 144e such that the fixing plate 144e has a groove disposed along a direction parallel to the first boundary line M, the roller 143e has a protrusion engaged with the groove, and the protrusion is embedded in the groove and can rotate in the groove.

In order to make the second display surface 1242 and the first display surface 1222 be in the same plane after the first side plate 142e and the first bottom plate 141e rotate relatively, the maximum distance between the roller 143e and the first side plate 142e may be equal to the distance between the fixing portion 122 and the first bottom plate 141 e. The maximum distance dimension from the roller 143e to the first side plate 142e may be the sum of the distance dimension from the center of the roller 143e to the first side plate 142e and the radius dimension of the roller 143 e. Of course, the fixing plate 144e on which the roller 143e is mounted may be an expansion plate having a moving stroke in a direction perpendicular to the first side plate 142e so that the second display surface 1242 may be flush with the first display surface 1222 after the first side plate 142e and the first bottom plate 141e are relatively rotated.

In order to keep the second display surface 1242 of the extending portion 124 in the same plane as the first display surface 1222 of the fixing portion 122 after the display screen 120 is adjusted to the second state, referring to fig. 12 to 14, a positioning hook 146e may be disposed at an end of the extending portion 124 away from the fixing portion 122, so that the positioning hook 146e can be hooked on the roller 143e after the display screen 120 is adjusted to the second state.

Of course, if the positioning hook 146e is hooked on the roller 143e, the display screen 120 is difficult to adjust from the second state to the first state, and based on this, referring to fig. 15, the driving structure 140 of the embodiment of the present application may further include a material rolling device 145e, so that the second display surface 1242 can be maintained on the same plane as the first display surface 1222 by the material rolling device 145e rolling and releasing the extending portion 124. Specifically, the material rolling device 145e may be located on one side of the first back face 1224 of the fixing portion 122, and the extending portion 124 and one side of the first side plate 142e away from the first bottom plate 141e may be slidably connected and then may be wound around the material rolling device 145e, so that when the first side plate 142e and the first bottom plate 141e rotate relatively, the material rolling device 145e can release the extending portion 124 to make the second display face 1242 and the first display face 1222 be in the same plane.

The winder 145e can include a third driving member and a take-up tray, the third driving member can be located on one side of the first back face 1224 of the fixing portion 122; the coil stock tray can be connected with the output shaft of the third driving part and can be driven by the output shaft of the third driving part to rotate. The extension portion 124 may be wound around a take-up reel. When the extending part 124 and the first bottom plate 141e rotate relatively, the third driving member can drive the material tray to rotate to release the extending part 124 wound on the material tray.

Referring to fig. 1 to 5, the number of the extensions 124 may be one. Of course, the number of the extensions 124 may be plural. Such as two, three, etc. When the number of the extending portions 124 is two, the two extending portions 124 may be connected to both ends of the fixing portion 122, respectively; the number of the driving structures 140 may also be two, and each extending portion 124 is correspondingly connected to one driving structure 140.

Of course, in order to simplify the structure of the folding screen assembly 100, when the number of the extension portions 124 is two, only one driving structure 140 may be provided, and the adjustment of the two extension portions 124 may be implemented by increasing the number of the driving structures 140. In the following, the connection between the two extending portions 124 and the one driving structure 140 is described in detail, and when the driving structure 140 includes the first telescopic member 142c and the second telescopic member 144c, as described above, referring to fig. 6 and 7, the number of the first telescopic members 142c may also be two when the number of the extending portions 124 is two, and each first telescopic member 142c is correspondingly connected to the pulling end 12442 of one extending portion 124. When the driving structure 140 includes the first driving element 141d, the screw 142d, the slider 143d, the worm wheel 144d and the worm 145d as described above, referring to fig. 10, the number of the second mounting holes 1432d and the number of the worm 145d may be two, and each worm 145d is inserted into one second mounting hole 1432 d. Each worm 145d is in meshing engagement with the worm gear 144d, and each worm 145d is correspondingly connected to the trailing end 12442 of one of the extensions 124. Referring to fig. 14, when the driving structure 140 includes the first bottom plate 141e and the first side plate 142e, the boundary line between each extending portion 124 and the fixing portion 122 is the first boundary line M, and the edges of the first bottom plate 141e corresponding to the two first boundary lines M may be respectively rotatably connected to one first side plate 142 e.

In order to keep the first display surface 1222 of the fixing portion 122 flat, a hard screen may be used as the fixing portion 122. Of course, when the flexible screen is used as the extension portion 124, in order to ensure that there is no connecting mark at the connecting position of the fixing portion 122 and the extension portion 124, the fixing portion 122 and the extension portion 124 are generally integrally formed, so that the fixing portion 122 is also the same flexible screen as the extension portion 124. To keep the first display surface 1222 of the fixing portion 122 flat when the fixing portion 122 is a flexible screen, the foldable screen assembly 100 may further include a supporting plate 190, see fig. 5 to 7. The supporting plate 190 is located between the fixing portion 122 and the driving structure 140 for supporting the fixing portion 122 so as to flatten the first display surface 1222. To avoid the supporting plate 190 from wearing the display screen 120, a buffer 192 is disposed at an end of the supporting plate 190 close to the first boundary line M. The support plate 190 may be a solid plate corresponding to the fixing portion 122 for achieving support of the entire fixing portion 122. The support plate 190 may be a frame plate corresponding to an edge portion of the fixing portion 122 to support the edge portion of the fixing portion 122. Of course, the first display surface 1222 may be connected to the supporting plate 190 in order to keep the first display surface 1222 flat when the supporting plate 190 is a frame plate. Specifically, the first display surface 1222 may be adhered to the support plate 190 by an adhesive.

The driving structure 140 can adjust the display screen 120 from the second state to the first state in addition to adjusting the display screen 120 from the first state to the second state. In the following, a detailed description is given to an implementation process of the driving structure 140 to adjust the display screen 120 from the second state to the first state, when the driving structure 140 includes the second driving part 142a, the first rotating rod 144a and the second rotating rod 146a, the second driving part 142a is only required to control the first rotating rod 144a to rotate reversely, and specifically, the second motor can be controlled to rotate reversely.
