Please refer to fig. 1. The embodiment of the application provides a battery pack fixing device which can comprise a conveying mechanism 1, a mounting mechanism (not shown in the figure) and a docking mechanism 2. The conveying mechanism 1 comprises a first support 11 for supporting the conveying mechanism 1 on a support surface.

The mounting mechanism is used for fixing the battery pack to the vehicle body. The docking mechanism 2 is provided in the conveying mechanism 1. The mounting mechanism is provided to the docking mechanism 2. The docking mechanism 2 is docked with the first positioning portion of the vehicle body, so that the mounting mechanism and the vehicle body are positioned in the first direction X and the second direction Y.

Of course, in other embodiments, one of the first direction X and the second direction Y may have two components of mutually perpendicular directions, wherein the other has a component of a direction perpendicular to the two mutually perpendicular directions. For example, if the two mutually perpendicular directions are two directions parallel to the support surface and the first direction X is the resultant of these two directions, then the second direction Y has a component of the direction perpendicular to the support surface.

In the present embodiment, for convenience of explanation, a direction parallel to the support surface is taken as the first direction X and the second direction Y, and the first direction X and the second direction Y are perpendicular to each other. More specifically, the left-right direction in fig. 1 is defined as a first direction X, and the up-down direction in fig. 1 is defined as a second direction Y. In fig. 1, the support surface is parallel to the paper.

The application provides a battery package fixing device, through setting up the docking mechanism 2 that can dock with the first location portion of automobile body, make installation mechanism and the automobile body that sets up in docking mechanism 2 can accomplish the location at first direction X and second direction Y to installation mechanism can be fixed the battery package to the automobile body on. Simultaneously with docking mechanism 2 setting in conveying mechanism 1, conveying mechanism 1 has first supporting part 11, can be along with the automobile body synchronous motion who conveys come to can accomplish the installation of battery package in step at the in-process that the automobile body was carried, thereby can improve the packaging efficiency, assemble the battery package in the automobile body fast.

In addition, the installation mechanism is arranged on the docking mechanism 2, so that the installation mechanism and the vehicle body can be positioned while the docking mechanism 2 and the vehicle body are docked and positioned, the installation mechanism can fix the battery pack on the vehicle body in time, and the battery pack can be quickly assembled.

The docking mechanism 2 is described in detail below.

As shown in fig. 1 and 2, the docking mechanism 2 includes a first mounting plate 21, a first moving member 22, a first power member 24, and a guide assembly 23.

The first mounting plate 21 is used to house the mounting mechanism. The first moving member 22 is slidably attached to a surface of the first mounting plate 21 opposite the support surface. The sliding connection may be a wire-rail slider structure, or other sliding connection, which is not limited in this application. The guide assembly 23 is in transmission connection with the first moving part 22, and the guide assembly 23 can be in butt joint with the first positioning part of the vehicle body. The first power member 24 is disposed on the first mounting plate 21 for driving the first moving member 22 to move. The first power member 24 may be a cylinder. The cylinder body of the cylinder is fixedly arranged on the first mounting plate 21. The piston rod of the cylinder extends in a direction parallel to the support surface and is fixedly connected to the first moving member 22. In other embodiments, the first power member 24 may be an electric cylinder, a linear motor, or the like.

The first power member 24 drives the first moving member 22 to move in a direction parallel to the supporting surface, and drives the guiding assembly 23 disposed on the first moving member 22 to move in a direction parallel to the supporting surface, so that the guiding assembly 23 is finally abutted to the first positioning portion of the vehicle body, and the mounting mechanism on the first mounting plate 21 and the vehicle body are positioned in a direction parallel to the supporting surface, that is, the positioning is completed in the first direction X and the second direction Y.

Specifically, the docking mechanism 2 may further include a second moving member 25 and a first link 26. The first moving member 22 is slidably connected to the surface of the first mounting plate 21 opposite to the supporting surface along the first direction X, and the second moving member 25 is slidably connected to the surface of the first mounting plate 21 opposite to the supporting surface along the second direction Y. The sliding connection can adopt a wire-rail sliding block structure or other sliding connection modes, and the application does not limit the sliding connection to the sliding connection mode. One end of the first link 26 is hinged to the first moving member 22 and the other end is hinged to the second moving member 25. The guide assembly 23 is disposed on the second moving member 25. The first power member 24 drives the first moving member 22 to move in the first direction X, and the first connecting member drives the second moving member 25 to move in the second direction Y through the first connecting rod 26, and drives the guiding assembly 23 disposed on the second moving member 25 to move in the second direction Y.

More specifically, the first links 26 are two in number and are symmetrically arranged. One ends of the two first connecting rods 26 are hinged to the same first moving member 22, and the other ends of the two first connecting rods 26 are hinged to the two second moving members 25, respectively. And one ends of the two second moving parts 25, which are far away from the supporting surface, are respectively and fixedly provided with a guide component 23. The provision of two guide assemblies 23 allows for more stable positioning. The two second moving members 25 move in opposite directions, so that the two guide assemblies 23 move in opposite directions. The moving end of the first power member 24 moves in the first direction X to drive the two guide assemblies 23 to move toward or away from each other in the second direction Y, which saves space.

The guide assembly 23 is described in detail below.

As shown in fig. 5, 6 and 7, the guide assembly 23 includes a connection seat 231, a moving seat 232, a first elastic member 237 and a positioning pin 236.

The connecting base 231 is disposed on the second moving member 25. Preferably, the connecting base 231 is fixedly installed on the second moving member 25. The movable base 232 is slidably connected to the connection base 231 along the third direction Z, and may adopt a structure of a wire rail 4 and a slider 5, for example. The first elastic element 237 extends along the third direction Z and is disposed between the connecting seat 231 and the moving seat 232. The positioning pin 236 is fixedly disposed at an end of the movable base 232 away from the supporting surface, and is configured to be abutted with the first positioning portion of the vehicle body. Accordingly, the first positioning portion of the vehicle body may be a guide hole.

The first direction X, the second direction Y and the third direction Z are intersected pairwise, and the first direction X, the second direction Y and the third direction Z are not on the same plane. In this specification, for convenience of description, a direction perpendicular to both the first direction X and the second direction Y is taken as the third direction Z. More specifically, a direction perpendicular to the paper surface in fig. 1 is defined as a third direction Z, that is, the third direction Z is a vertical up-down direction. In this specification, for a particular component, the surface facing away from or remote from the support surface is the upper surface of the component and the surface facing towards or close to the support surface is the lower surface of the component.

Because the moving seat 232 is slidably connected to the connecting seat 231 along the third direction Z, the positioning pin 236 is fixedly disposed at an end of the moving seat 232 away from the supporting surface, and a first elastic member 237 extending along the third direction Z is disposed between the connecting seat 231 and the moving seat 232, so that the positioning pin 236 can slide along the third direction Z relative to the connecting seat 231, and the positioning pin 236 has a floating performance along the third direction Z. When the positioning pin 236 is not inserted into the guide hole on the vehicle body, it can automatically retract along the direction opposite to the third direction Z; the positioning pin 236 can be automatically ejected out of the insertion guide hole in the third direction Z when aligned with the guide hole in the vehicle body.

In this embodiment, the guiding assembly 23 may further include a seventh power member 233, an eighth power member 235 and a fourth moving member 234. The seventh power member 233 is disposed on the connecting seat 231 and used for driving the moving seat 232 to move. The eighth power member 235 is disposed on the moving base 232 for driving the fourth moving member 234 to move. The positioning pin 236 is fixedly disposed at an end of the fourth moving member 234 away from the supporting surface.

The seventh power member 233 may be a cylinder. The cylinder body of the cylinder is fixedly arranged on the connecting seat 231. The piston rod of the cylinder extends and retracts in the third direction Z and is connected to the movable base 232. Specifically, the piston rod of the air cylinder abuts against the moving seat 232 through the first elastic member 237, the moving seat 232 is connected to the piston rod of the air cylinder through the adjusting rod 238, and the compression amount of the first elastic member 237 can be adjusted in the third direction Z through the adjusting rod 238. The adjustment rod 238 and the first elastic member 237 are configured to elastically couple the connection seat 231 and the moving seat 232, so that the positioning pin 236 has a buffering function, and when the positioning pin 236 is not engaged with the first positioning portion, the positioning pin 236 is contracted, thereby preventing damage to the positioning pin 236. In other embodiments, the seventh power member 233 may also be an electric cylinder, a linear motor, etc. The first elastic member 237 may be a spring.

The eighth power member 235 may be a cylinder. The cylinder body of the cylinder is fixedly arranged on the movable base 232. The piston rod of the cylinder extends and retracts in the third direction Z and is fixedly connected with the fourth moving member 234. In other embodiments, the eighth power member 235 may also be an electric cylinder, a linear motor, or the like.

In this embodiment, the seventh power member 233 is actuated to drive the eighth power member 235 and the positioning pin 236 to move upward, and the eighth power member 235 is actuated to continue to drive the positioning pin 236 to move upward. With the guide assembly 23 of this structure, the height thereof can be reduced, thereby reducing the overall height of the conveyor 1. In other embodiments, only one of the seventh power member 233 and the eighth power member 235 may be reserved, that is, one power member may be provided instead of the seventh power member 233 and the eighth power member 235, and one large stroke cylinder may be provided instead.

To facilitate insertion of the two positioning pins 236 into the first positioning portion of the vehicle body, the docking mechanism 2 further includes a floating assembly 27. The floating assembly 27 has a moving end connected to the first mounting plate 21. The float assembly 27 is described in detail below.

The mounting member 272 is fixedly disposed on a surface of the bottom plate 271 opposite to the supporting surface. The first guide bar 273 is slidably coupled in the mounting member 272 in the first direction X. For example, a first through hole extending in the first direction X may be formed in the mounting part 272, and the first guide bar 273 is slidably coupled to the mounting part 272 through the first through hole. The third moving member 274 is fixedly disposed at both ends of the first guide bar 273. The first spring 275 is sleeved on the first guide rod 273 between the mounting member 272 and the third moving member 274, and two ends of the first spring 275 are abutted against the third moving member 274 and the mounting member 272. So that the first mounting plate 21 has floating performance in the first direction X.

The second guide rod 276 is fixedly disposed between the two third moving members 274 distributed along the second direction Y. The fixing block 277 is fixedly disposed on a surface of the first mounting plate 21 facing the supporting surface, and the second guide rod 276 is slidably coupled to the fixing block 277. For example, a second through hole extending in the second direction Y may be provided on the fixed block 277, and the second guide rod 276 is slidably connected to the fixed block 277 through the second through hole. The second spring 278 is sleeved on the second guide rod 276 between the third moving member 274 and the fixed block 277, and two ends of the second spring 278 are abutted against the third moving member 274 and the fixed block 277. So that the first mounting plate 21 has floating performance in the second direction Y.

In the present embodiment, the floating assembly 27 is located on the surface of the first mounting plate 21 facing the support surface, and the guide assembly 23 is located on the surface of the first mounting plate 21 facing away from the support surface. The docking mechanism 2 is further provided with an adjustment assembly 28 for clamping the vehicle body in the third direction Z to complete the positioning of the mounting mechanism and the vehicle body in the third direction Z. The adjustment assembly 28 may be located on a surface of the first mounting plate 21 facing away from the support surface.

The adjustment assembly 28 is described in detail below.

As shown in fig. 8, 9 and 10, the adjustment assembly 28 includes a fixed seat 281, a first seat 282, a second power member 287, a first jaw 284 and a second jaw 285.

The fixing base 281 is fixed to the first mounting plate 21. The first support 282 is slidably connected to the fixing seat 281 along the third direction Z, for example, the sliding connection may be implemented by a structure of a wire track 4 and a slider 5. The surface 2821 of the first abutment 282 remote from the support surface is used to position the mounting mechanism. First jaw 284 is fixed relative to first seat 282. The second clamping jaw 285 is slidably connected to the first support 282 along the third direction Z, for example, the second clamping jaw may be slidably connected to the first support by a structure of a wire track 4 and a sliding block 5. As shown in fig. 8 and 9, first jaw 284 is a lower jaw and second jaw 285 is an upper jaw.

The second motive member 287 is adapted to move the second jaw 285 relative to the first jaw 284. The second power member 287 may be a cylinder. The cylinder body of the cylinder is fixedly arranged on the second mounting plate 283. The piston rod of the cylinder extends and retracts in the third direction Z and is fixedly connected with the second clamping jaw 285. In other embodiments, the second motive member 287 may be an electric cylinder, a linear motor, or the like.

In this embodiment, the adjustment assembly 28 may further include a second mounting plate 283. The second mounting plate 283 is fixedly connected to the first support 282, the first clamping jaw 284 is fixedly connected to the second mounting plate 283, the second clamping jaw 285 is slidably connected to the second mounting plate 283 along the third direction Z, and the second power member 287 is disposed on the second mounting plate 283.

In a preferred embodiment, the adjustment assembly 28 may further include a third power member 286. The third power element 286 is disposed on the fixing base 281 for offsetting at least a portion of the gravity of the first support 282 and the components on the first support 282. The third power member 286 may be a cylinder. The cylinder body of the air cylinder is fixedly arranged on the fixed seat 281. The piston rod of the cylinder extends and retracts in the third direction Z and is fixedly connected to the first support 282. In other embodiments, the third power element 286 can be an electric cylinder, a linear motor, or the like.

In the initial state, the third power member 286 is used to counteract the gravity of the component disposed on the second mounting plate 283 and the gravity of the second mounting plate 283. When the piston rod of the second power member 287 is retracted, the second clamping jaw 285 will be moved relative to the first clamping jaw 284, thereby clamping the vehicle body, for example, the rear bumper of the vehicle body.

The third power member 286 is provided to enable the second mounting plate 283 to be in a floating state, thereby facilitating rapid clamping of the vehicle body. For example, when the clamped region of the vehicle body is located at a position just above the middle between the first clamping jaw 284 and the second clamping jaw 285, after the second clamping jaw 285 contacts the surface of the vehicle body first, since the vehicle body does not move up and down, when the piston rod of the second power member 287 continues to contract, the first clamping jaw 284 will be driven to move up, thereby clamping the vehicle body quickly.

In this embodiment, the first supporting portion 11 may include a first roller, and the first roller may roll on the supporting surface, so as to drive the conveying mechanism 1 to move synchronously with the conveyed vehicle body. Of course, the first supporting portion 11 may also adopt other structures, such as a structure of a wire track and a sliding block, which is not limited in this application.

The conveyor 1 is described in detail below.

As shown in fig. 11 and 12, the conveying mechanism 1 further includes a second support 12, a second roller 13, and a driving member 14.

The first roller is rotatably mounted to the second support 12. The first rollers are provided in plural, and can be installed at opposite ends of the second support 12. As shown in fig. 11, the number of the first rollers is at least four, and the first rollers can support the conveying mechanism 1 on the supporting surface and drive the conveying mechanism 1 to move synchronously with the vehicle body.

The second roller 13 can be switched between a first position disengaged from the support surface and a second position supported on the support surface. When the second roller 13 is positioned at the first position, the conveying mechanism 1 can move together with the vehicle body; when the second roller 13 is in the second position, the transport mechanism 1 can be moved independently. The driving member 14 is provided on the second support 12.

The output end of the driving piece 14 is in transmission connection with the second roller 13. When the second roller 13 is located at the second position, the driving member 14 drives the second roller 13 to rotate, so that the conveying mechanism 1 can move independently. Specifically, the driving member 14 may be a motor, an output end of the motor may be connected to a speed reducer, and two output ends of the speed reducer are both in transmission connection with a coupling 19. The coupling 19 may be a universal coupling 19. The other end of the coupling 19 is in transmission connection with the second roller 13, so that the second roller 13 can be driven to rotate by a motor.

In the present embodiment, the conveying mechanism 1 further includes a bearing housing 15, a second link 16, and a fourth power member 17.

The bearing block 15 is connected with one end of the coupling 19 far away from the driving piece 14, and the second roller 13 is rotatably arranged on the bearing block 15. The second link 16 has opposite first and second ends, the first end being fixed to the bearing seat 15 and the second end being hinged to the moving end of the fourth power member 17. Second link 16 is hingedly connected to second support 12 between the first and second ends, such as at a midpoint of second link 16, although other locations between the first and second ends are possible. The fourth power member 17 is disposed on the second support 12 and drives the second connecting rod 16 to rotate, so that the second roller 13 is switched between the first position and the second position.

The fourth power member 17 may be a cylinder. The cylinder body of the cylinder is fixedly arranged on the second support 12. The piston rod of the cylinder extends and retracts in the third direction Z and is hinged to the second end of the second link 16. In other embodiments, the fourth power member 17 may also be an electric cylinder, a linear motor, or the like.

When the piston rod of the fourth power member 17 is retracted, the second connecting rod 16 is driven to move clockwise, so that the second roller 13 is disengaged from the supporting surface and is located at the first position. When the piston rod of the fourth power member 17 extends, the second connecting rod 16 is driven to move counterclockwise, so that the second roller 13 is pressed against the supporting surface and located at the second position.

As shown in fig. 11, in the present embodiment, a ninth power tool 18 is fixed to the conveying mechanism 1. The moving end of the ninth power member 18 is fixedly connected to the bottom plate 271 of the docking mechanism 2. The ninth power member 18 may be a cylinder. The cylinder body of the cylinder is fixedly arranged on the conveying mechanism 1. The piston rod of the cylinder extends and retracts in the second direction Y and is fixedly connected with the bottom plate 271 of the docking mechanism 2. In other embodiments, the ninth power member 18 can also be an electric cylinder, a linear motor, etc.

The base plate 271 is slidably connected to the conveying mechanism 1 in the second direction Y. The sliding connection may be a structure of the wire track 4 and the sliding block, or other sliding connection, which is not limited in this application. The ninth power part 18 acts to drive the docking mechanism 2 to move, and drives the docking mechanism 2 to move from one end of the conveying mechanism 1 to the middle area of the conveying mechanism 1 along the second direction Y, so that a battery pack can be mounted and fixed on the vehicle body. For a part of the vehicle body which does not need to be provided with or fixed with a battery pack, the ninth power part 18 is not started, so that the docking mechanism 2 is always positioned at one end of the conveying mechanism 1 and can avoid the vehicle body, and the vehicle body can pass through the conveying mechanism 1.

In the present embodiment, the battery pack fixing device may further include a blocking mechanism 3 fixed to the conveying mechanism 1. The blocking mechanism 3 is described in detail below.

As shown in fig. 13 and 14, the blocking mechanism 3 includes a mount 31 and a first blocking member 35.

The mounting seat 31 is fixed to the conveying mechanism 1. The first blocking member 35 is slidably connected to the mounting seat 31 along the first direction X, and is used for blocking the vehicle body in the first direction X, so that the requirement of compatibility is met, that is, the first blocking member 35 can adjust the distance between the mounting mechanism on the conveying mechanism 1 and the blocking mechanism 3 by sliding along the first direction X, so that the requirement of mounting and fixing the battery pack in different lengths/widths of the vehicle body can be met.

In the present embodiment, the blocking mechanism 3 may further include a floating seat 36, a second elastic member 37, a second blocking member 38, a fifth power member 39, and a sixth power member 310.

The floating seat 36 is slidably connected to a surface of the mounting seat 31 facing away from the supporting surface along the first direction X, and the first blocking member 35 and the second blocking member 38 are mounted to the floating seat 36. The second elastic element 37 is abutted between the floating seat 36 and the mounting seat 31 along the first direction X. The second elastic member 37 may be a spring.

The second blocking member 38 and the first blocking member 35 move in opposite directions and cooperate to clamp the vehicle body. The fifth power member 39 and the sixth power member 310 are mounted to the floating mount 36. The fifth power member 39 is used to drive the first blocking member 35 and the sixth power member 310 is used to drive the second blocking member 38.

The fifth power element 39 may be a cylinder. The cylinder body of the cylinder is fixedly arranged on the floating seat 36. The piston rod of the cylinder extends and retracts in the first direction X and is fixedly connected to the first blocking member 35. In other embodiments, the fifth power component 39 can also be an electric cylinder, a linear motor, etc.

The sixth power member 310 may be a cylinder. The cylinder body of the cylinder is fixedly arranged on the floating seat 36. The piston rod of the cylinder extends in the first direction X and is fixedly connected to the second blocking element 38. In other embodiments, the sixth power member 310 may also be an electric cylinder, a linear motor, or the like.

In a particular embodiment, the mounting seat 31 may comprise a second support 32 for supporting the blocking mechanism 3 on a support surface. The blocking mechanism 3 can move synchronously with the conveyed vehicle body via the second support portion 32. The second supporting portion 32 may include a plurality of rollers. Of course, the second supporting portion 32 may also adopt other structures, such as a structure of a wire track and a slider, which is not limited in this application.

Further, the blocking mechanism 3 may further include a third seat 33. The third support 33 is slidably coupled to the mounting seat 31 along the first direction X. The sliding connection may be a wire track and slider structure, or other sliding connection, which is not limited in this application. The floating seat 36 is slidably connected to the surface of the third seat 33 facing away from the supporting surface. The sliding connection may be a structure of a wire track 4, a sliding block 5, or other sliding connection, which is not limited in this application. The second elastic element 37 is set between the floating seat 36 and the third seat 33 along the first direction X.

In particular, the blocking mechanism 3 may further comprise a tenth power member 34. The tenth power member 34 is disposed on the mounting seat 31 for driving the third support 33 to move. The tenth power member 34 may be a cylinder. The cylinder body of the cylinder is fixedly arranged on the mounting seat 31. The piston rod of the cylinder extends and retracts in the first direction X and is fixedly connected to the third support 33. In other embodiments, the ninth power member 18 can also be an electric cylinder, a linear motor, etc.

The tenth power part 34 and the third support 33 are arranged, so that the compatibility of the battery pack fixing device can be improved, different lengths/widths of the vehicle body can be met, and when the tenth power part 34 acts, the distance between the mounting mechanism on the conveying mechanism 1 and the blocking mechanism 3 can be adjusted, so that the requirements of mounting and fixing the battery packs with different lengths/widths of the vehicle body can be met.

Specifically, the upper end of the floating seat 36 is provided with a power member mounting seat 311, and the fifth power member 39 and the sixth power member 310 are fixedly arranged on the floating seat 36 through the power member mounting seat 311. The first stop 35 comprises a third jaw and the second stop 38 comprises a fourth jaw. The power member mounting base 311 is fixedly provided with a third connecting rod 312. One end of the third connecting rod is fixedly arranged on the power element mounting seat 311, and the other end of the third connecting rod is hinged with the fourth connecting rod 313. One end of the fourth connecting rod 313 is hinged with the third connecting rod, and the other end is hinged with the third clamping jaw. The moving end of the fifth power part 39 is hinged to the third clamping jaw, and when the fifth power part 39 acts, the third clamping jaw is driven to swing, so that the vehicle body is blocked. The moving end of the sixth power member 310 is hinged to the fourth clamping jaw, and when the sixth power member 310 acts, the fourth clamping jaw is driven to swing, so that the sixth clamping jaw and the third clamping jaw are matched to clamp the vehicle body.

In the present embodiment, one end of the conveying mechanism 1 can be fixedly connected with two blocking mechanisms 3, so that the blocking and clamping of the vehicle body are more effective.

In a specific application scenario, the vehicle body is conveyed from the upper side of the conveying mechanism 1, and when the vehicle body does not need to fix the battery pack, the conveying mechanism 1 transports the vehicle body to the next process position by using the first supporting portion 11. When the vehicle body needs to fix the battery pack, the blocking mechanism 3 acts to block and clamp the vehicle body. After the blocking mechanism 3 clamps the vehicle body, the ninth power member 18 operates to drive the docking mechanism 2 to move to a region of the conveying mechanism 1 corresponding to a region of the vehicle body where the battery pack needs to be fixed (for example, the region may be substantially the middle region of the conveying mechanism 1), and the docking mechanism 2 operates to enable the positioning pin 236 on the guide assembly 23 to be inserted into the guide hole in the vehicle body, so that the mounting mechanism on the first mounting plate 21 and the vehicle body are positioned in the first direction X and the second direction Y (i.e., the left-right direction and the front-back direction). Thereafter, the adjustment assembly 28 is actuated to clamp the body from the third direction Z (i.e., the vertical direction) such that the mounting mechanism is positioned with the body in the third direction Z.

In the embodiment, in the process of conveying the vehicle body, the butt joint mechanism 2 on the conveying mechanism 1 is in butt joint with the blocked positioning hole on the vehicle body, and after the butt joint, the vehicle body moves and simultaneously drives the conveying mechanism 1 to move synchronously. During the synchronous movement of the vehicle body and the conveying mechanism 1, the mounting mechanism provided on the docking mechanism 2 acts for mounting the fastener, such as screwing, so that the battery pack is fixed in the vehicle. Therefore, the battery pack can be synchronously installed and fixed in the conveying process of the vehicle body, the assembling efficiency can be improved, and the battery pack can be rapidly assembled in the vehicle body.
