These hinges utilize a buffering mechanism to provide a smooth closing process, reducing the noise caused by the door colliding with the cabinet body.

DETAILED DESCRIPTION
[0031] For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
[0032] In the description of the present invention, it should be noted that the terms "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the modules or components referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limiting the present invention.
[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.
[0034] Example 1 See Figure 1-10 The present invention first provides a hinge structure capable of achieving a buffered opening, comprising a hinge cup 1 fixed to a cabinet door and a hinge arm 2 fixed to a cabinet body. A rocker assembly is disposed between the hinge cup 1 and the hinge arm 2 to achieve hinged opening and closing. The hinge structure further comprises a first buffer assembly 5 disposed on the hinge cup 1. The first buffer assembly 5 includes a first buffer and a first drive block 501 in transmission engagement with the first buffer. The first drive block 501 is in transmission connection with the rocker assembly.
[0035] Among them, when the hinge cup 1 is driven to open, the rocker arm assembly can be driven to swing synchronously, and the rocker arm assembly can drive the first drive block 501 to move; when the hinge cup 1 is driven to open to a certain angle, the rocker arm assembly drives the first drive block 501 to drive the first buffer to produce a buffering effect on the hinge cup 1, thereby realizing opening buffering.
[0036] Therefore, the present invention provides a first buffer assembly 5 on the hinge cup 1. When the hinge cup 1 is driven to open to a certain angle, the first buffer in the first buffer assembly 5 can produce a buffering effect on the hinge cup 1, thereby slowing down the opening speed of the cabinet door, thereby avoiding damage to the cabinet door and hinge structure due to violent impact, and preventing noise from being generated. In addition, by slowing down the opening speed of the cabinet door, cabinet door pinching accidents can be prevented, reducing safety hazards.
[0037] See Figure 2 as well as Figure 7-8 The hinge cup 1 is further provided with a groove 101, which is configured to accommodate at least part of the rocker arm assembly when the hinge cup 1 is closed. Preferably, the first buffer assembly 5 is located outside the groove 101. Thus, by arranging the first buffer assembly 5 outside the groove 101 of the hinge cup 1, the external space is effectively utilized, the problem of limited internal space is avoided, and assembly and disassembly are more convenient.
[0038] Preferably, the first buffer assembly 5 is located on the outer side of the groove 101; the rocker arm assembly includes an outer rocker arm 3, one end of the outer rocker arm 3 is hinged to the hinge cup 1 and is located inside the groove 101, and the other end is hinged to the hinge arm 2; the first drive block 501 is hinged on the hinge cup 1 and is located on an outer side of the groove 101; one side of one end of the outer rocker arm 3 is transmission-connected to the first drive block 501.
[0039] Specifically, it also includes a first drive shaft 6 that is passed through the first drive block 501 and linked to the first drive block 501. A first avoidance hole 102 is opened on one side of the hinge cup 1, and a first mounting hole 301 is opened on one side of one end of the outer rocker arm 3. The first drive shaft 6 passes through the first avoidance hole 102 and is clamped and fixed in the first mounting hole 301 to realize a transmission connection with the outer rocker arm 3; thus, when the hinge cup 1 is driven to open, the outer rocker arm 3 can be driven to swing synchronously, and the outer rocker arm 3 synchronously drives the first drive block 501 to rotate.
[0040] In this embodiment, a first fixing hole 5011 is defined on the first driving block 501 , and the first driving shaft 6 passes through and is fixed in the first fixing hole 5011 to achieve linkage with the first driving block 501 .
[0041] Therefore, a transmission connection is achieved between one side of the outer rocker arm 3 and the first drive block 501 through the first drive shaft 6. When the hinge cup 1 is fully closed, the first drive shaft 6 will be located at the side position of the rocker arm assembly, and it does not occupy the depth space of the groove 101. Therefore, there is no need to increase the depth of the groove 101 of the hinge cup 1, so that the thickness of the hinge cup 1 can be made thinner, and then it can be assembled on a door panel with thinner thickness, which is more versatile.
[0042] In this embodiment, a first hinge hole 302 is provided on both sides of one end of the outer rocker arm 3, a third hinge hole 5012 is provided on the first drive block 501, and a fourth hinge hole 103 is provided on both side walls of the groove 101 of the hinge cup 1; thus, the first hinge shaft 8 is used to pass through the two first hinge holes 302, the two fourth hinge holes 103 and the third hinge hole 5012 respectively, so as to realize the hinge connection of one end of the outer rocker arm 3 and the first drive block 501 to the hinge cup 1.
[0043] See also Figure 2-4 The first buffer is a first oil cylinder 503 and includes a first cylinder body 5031 and a first piston rod 5032 movably arranged on the first cylinder body 5031, wherein when the first piston rod 5032 is driven to compress and move relative to the first cylinder body 5031, it can produce a buffering effect; the first buffer assembly 5 also includes a first transmission plate 502, one end of the first transmission plate 502 is used to be transmission-connected with the first driving block 501, and the other end of the first transmission plate 502 is transmission-connected with the first cylinder body 5031 or the first piston rod 5032; preferably, one end of the first transmission plate 502 is provided with a first protrusion 5021, and the first driving block 501 is provided with a first protrusion 5013, and the first protrusion 5021 is used to abut with the first protrusion 5013 to achieve transmission connection; the other end of the first transmission plate 502 is bent with a first bent portion 5022, and the first bent portion 5022 is used to abut with the first piston rod 5032 to achieve transmission connection.
[0044] Therefore, when the hinge cup 1 is driven to open to a certain angle, the first protrusion 5013 on the first driving block 501 can abut the first protrusion 5021 on the first transmission plate 502, and then drive the first transmission plate 502 to move. The first bent portion 5022 on the first transmission plate 502 can abut and compress the first piston rod 5032 to produce a buffering effect on the hinge cup 1 until the hinge cup 1 is fully opened; conversely, when the hinge cup 1 is driven to close, it can synchronously drive the outer rocker arm 3 and the first driving block 501 to rotate and reset, the first driving block 501 disengages from the first transmission plate 502, the first piston rod 5032 extends out to reset and drive the first transmission plate 502 to reset and move until the first piston rod 5032 is fully reset.
[0045] Of course, it should be noted that in other embodiments, the first oil cylinder 503 can also be reversed, and the first transmission plate 502 can be used to compress the first cylinder body 5031 to produce a buffering effect on the hinge cup 1, which can also achieve the same technical effect and is not limited here.
[0046] See Figure 2-3 as well as Figure 5 The hinge structure further includes a first mounting seat 7 disposed on one side of the hinge cup 1 and shielding the first buffer assembly 5. The first buffer and the first transmission plate 502 are both disposed within the first mounting seat 7. Two hooks 704 are provided at one end of the first mounting seat 7, spaced apart vertically. The hinge cup 1 is provided with two locking holes 106, spaced apart vertically. By engaging the two hooks 704 in the two locking holes 106, the first mounting seat 7 can be fixed in position. A limiting hole 703 is provided at the other end of the first mounting seat 7. Sixth hinge holes 105 are provided on both side walls of the recess 101 of the hinge cup 1. The second pin 902 is passed through the limiting hole 703 and the sixth hinge hole 105, respectively, to limit the other end of the first mounting seat 7 and thereby secure the first mounting seat 7 to the hinge cup 1.
[0047] Specifically, the first mounting seat 7 is provided with a first mounting groove 701 adapted to the shape of the first cylinder body 5031 and a second mounting groove 702 adapted to the shape of the first transmission plate 502. The first oil cylinder 503 is placed in the first mounting groove 701, and the first transmission plate 502 is placed in the second mounting groove 702. When the first mounting seat 7 is assembled and fixed on the hinge cup 1, the first oil cylinder 503 and the first transmission plate 502 can be limited and fixed.
[0048] See Figure 2 and Figure 4The rocker arm assembly also includes an inner rocker arm 4 located inside the outer rocker arm 3, one end of the inner rocker arm 4 is hinged to the hinge cup 1, and the other end is hinged to the hinge arm 2; specifically, the end of the inner rocker arm 4 close to the hinge cup 1 is bent to form a second hinge hole 401, and both side walls of the groove 101 of the hinge cup 1 are provided with a fifth hinge hole 104; thus, one end of the inner rocker arm 4 can be hinged to the hinge cup 1 by using the first stitch 901 to pass through the two fifth hinge holes 104 and the second hinge hole 401 respectively.
[0049] In this embodiment, the first pin 901 and the second pin 902 are integrally formed to form a double pin 9 .
[0050] Therefore, the opening process of the hinge structure in this embodiment is as follows: When the hinge cup 1 is in the fully closed state (such as Figure 7-8 As shown), at this time, the first protrusion 5013 on the first driving block 501 is located at one end of the first avoidance hole 102. When the hinge cup 1 is driven to open, the outer rocker arm 3 can be driven to rotate synchronously. The outer rocker arm 3 can drive the first driving block 501 to rotate in the counterclockwise direction until the first protrusion 5013 on the first driving block 501 abuts against the first protrusion 5021 of the first transmission plate 502 (as shown). Figure 9-10 As shown), at this time, the hinge cup 1 continues to be driven to open, and the first driving block 501 continues to rotate in the counterclockwise direction and drives the first transmission plate 502 to compress the first piston rod 5032 to achieve buffering, until the hinge cup 1 is fully opened (as shown). Figure 4-5 As shown), at this time, the first transmission plate 502 compresses the first piston rod 5032 to the bottom, and the first protrusion 5013 on the first driving block 501 rotates to the other end of the first avoidance hole 102.
[0051] Example 2 See Figure 11-19 The hinge structure of this embodiment, based on the first embodiment, additionally incorporates a second buffer assembly 10 to provide a buffered closing effect on the hinge cup 1. The second buffer assembly 10 is mounted on the hinge cup 1 and includes a second buffer and a second drive block 1001 that engages with the second buffer. The second drive block 1001 is in transmission connection with the rocker assembly. When the hinge cup 1 is driven to close, the rocker assembly is simultaneously driven to swing, which in turn drives the second drive block 1001 to move. When the hinge cup 1 is closed to a certain angle, the rocker assembly drives the second drive block 1001 to actuate the second buffer, which provides a buffering effect on the hinge cup 1, achieving a buffered closing effect.
[0052] Therefore, by arranging the first buffer component 5 and the second buffer component 10 at the hinge cup 1, the hinge structure has both opening buffer and closing buffer functions, thereby slowing down the opening and closing speed of the cabinet door, avoiding pinching or collision accidents, and at the same time preventing the cabinet door from violently colliding with other objects and causing damage to the cabinet door and the hinge structure, thereby extending the service life of the product; in addition, by slowing down the opening and closing speed of the cabinet door, it can also avoid the cabinet door from violently colliding with other objects and generating huge noise, thereby creating a quiet environment and improving the user experience.
[0053] Preferably, the second buffer component 10 is arranged outside the groove 101 of the hinge cup 1, thereby effectively utilizing the external space and avoiding the problem of limited internal space; more preferably, the first buffer component 5 and the second buffer component 10 are respectively arranged on the two outer sides of the groove 101 of the hinge cup 1, so that the product can be subjected to more uniform force and the layout is more compact.
[0054] Specifically, the hinge cup 1 further includes a second drive shaft 11 that passes through the second drive block 1001 and is in interlocking relationship with the second drive block 1001. A second avoidance hole 107 is defined on the other side of the hinge cup 1, and a second mounting hole 303 is defined on the other side of one end of the outer rocker arm 3. The second drive shaft 11 passes through the second avoidance hole 107 and is engaged within the second mounting hole 303 to achieve a transmission connection with the outer rocker arm 3. The second mounting hole 303 is rotatable relative to the second drive shaft 11. Thus, when the hinge cup 1 is driven to close, the outer rocker arm 3 is synchronously driven to swing. The outer rocker arm 3 rotates relative to the second drive block 1001 through the second mounting hole 303 until both ends of the second mounting hole 303 abut against the second drive shaft 11, thereby driving the second drive block 1001 to rotate.
[0055] In this embodiment, a second fixing hole 10011 is defined on the second driving block 1001 , and the second driving shaft 11 passes through and is fixed on the second fixing hole 10011 to achieve linkage with the second driving block 1001 .
[0056] In this embodiment, a seventh hinge hole 10012 is provided on the second driving block 1001. The outer rocker arm 3 and the second driving block 1001 can be hinged to the hinge cup 1 by using the first hinge shaft 8 to pass through the two first hinge holes 302, the two fourth hinge holes 103 and the seventh hinge hole 10012 respectively.
[0057] Specifically, the second buffer is a second oil cylinder 1003 and includes a second cylinder body 10031 and a second piston rod 10032 movably disposed on the second cylinder body 10031. The second buffer assembly 10 also includes a second transmission plate 1002, one end of which is configured to be transmission-connected to the second drive block 1001, and the other end of which is transmission-connected to the second cylinder body 10031 or the second piston rod 10032. When the hinge cup 1 is driven to close to a certain angle, the second drive block 1001 drives the second cylinder body 10031 to extend or retract the second piston rod 10032 via the second transmission plate 1002 to provide a buffering effect on the hinge cup 1.
[0058] In this embodiment, when the second piston rod 10032 is driven to move in compression relative to the second cylinder body 10031, it can produce a buffering effect; preferably, one end of the second transmission plate 1002 is provided with a second protrusion 10021, and the second drive block 1001 is provided with a second protrusion 10013, and the second protrusion 10021 is used to abut with the second protrusion 10013 to achieve a transmission connection; the other end of the second transmission plate 1002 is bent with a second bent portion 10022, and the second bent portion 10022 is used to abut with the second piston rod 10032 to achieve a transmission connection.
[0059] Therefore, when the hinge cup 1 is driven to close to a certain angle, the second protrusion 10013 on the second driving block 1001 can abut the second protrusion 10021 on the second transmission plate 1002, and then drive the second transmission plate 1002 to move. The second bent portion 10022 on the second transmission plate 1002 can abut and compress the second piston rod 10032 to produce a buffering effect on the hinge cup 1 until the hinge cup 1 is completely closed; on the contrary, when the hinge cup 1 is driven to open, the outer rocker arm 3 can be synchronously driven to rotate and reset. The outer rocker arm 3 rotates relative to the second driving block 1001 through the second mounting hole 303, and the second piston rod 10032 extends out to reset and simultaneously drives the second transmission plate 1002 and the second driving block 1001 to reset. Subsequently, the outer rocker arm 3 abuts the second driving block 1001 through the second mounting hole 303 to drive the second driving block 1001 to reset and rotate.
[0060] Of course, it should be noted that in other embodiments, the second oil cylinder 1003 can also be installed in reverse, and the second cylinder body 10031 can be compressed by the second transmission plate 1002 to produce a buffering effect on the hinge cup 1, which can also achieve the same technical effect and is not limited here.
[0061] In addition, the hinge structure further includes a second mounting seat 12 disposed on the other side of the hinge cup 1 and shielding the second buffer assembly 10. The second buffer and the second transmission plate 1002 are both disposed within the second mounting seat 12. The structure and assembly method of the second mounting seat 12 are identical to those of the first mounting seat 7 and will not be described in detail herein.
[0062] The closing process of the hinge structure in this embodiment is as follows: When the hinge cup 1 is in the fully opened state (such as Figure 14-15 As shown), at this time, the second protrusion 10013 on the second driving block 1001 is located at one end of the second avoidance hole 107. When the hinge cup 1 is driven to close, the outer rocker arm 3 can be synchronously driven to rotate, and the outer rocker arm 3 drives the second driving block 1001 to rotate counterclockwise until the second protrusion 10013 on the second driving block 1001 abuts against the second protrusion 10021 of the second transmission plate 1002 (as shown). Figure 18-19 As shown), at this time, the hinge cup 1 continues to be driven to close, and the second driving block 1001 continues to rotate in the counterclockwise direction and drives the second transmission plate 1002 to compress the second piston rod 10032 to achieve buffering until the hinge cup 1 is completely closed (as shown). Figure 16-17 As shown), at this time, the second transmission plate 1002 compresses the second piston rod 10032 to the bottom, and at this time, the second protrusion 10013 on the second driving block 1001 rotates to the other end of the second avoidance hole 107.
[0063] Therefore, the hinge structure in this embodiment can simultaneously achieve opening and closing buffering of the hinge cup 1, with more diverse functions and wider applicability.
[0064] Example 3 See Figure 20-23 The hinge structure of this embodiment is based on the first embodiment, with the addition of a third buffer assembly to achieve closing buffering for the hinge cup 1. The difference from the second embodiment is that the third buffer assembly in this embodiment is arranged in the hinge arm 2 rather than in the hinge cup 1; wherein, the third buffer assembly includes at least a third buffer and a third drive block that is in transmission with the third buffer, and the third drive block is in transmission connection with the rocker assembly; when the hinge cup 1 is driven to close, the rocker assembly can be synchronously driven to swing, and the rocker assembly can drive the third drive block to move; when the hinge cup 1 is driven to close to a certain angle, the rocker assembly drives the third drive block to drive the third buffer to operate, and the third buffer produces a buffering effect on the hinge cup 1 to achieve closing buffering.
[0065] Specifically, the third buffer is a third oil cylinder 13, comprising a third cylinder body 1301 and a third piston rod 1302 movably mounted on the third cylinder body 1301. When the third piston rod 1302 is extended and moved relative to the third cylinder body 1301, it produces a buffering effect. The third driving block is a transmission block 14, which is hinged within the hinge arm 2 via a third hinge shaft 16. One end of the transmission block 14 is articulated to the inner rocker arm 4 via a second hinge shaft 15, and the other end of the transmission block 14 is articulated to the third piston rod 1302 via a fourth hinge shaft 17. Furthermore, the third cylinder body 1301 is articulated to the hinge arm 2 via a fifth hinge shaft 18.
[0066] Thus, when the hinge cup 1 is in the fully opened state (eg Figure 20-21 As shown), the third piston rod 1302 is in a retracted state. When the hinge cup 1 is driven to close, it can drive the inner rocker arm 4 to swing until the hinge cup 1 is closed to a certain angle (such as Figure 22 As shown), the inner rocker arm 4 drives the transmission block 14 to rotate, and the transmission block 14 can drive the third piston rod 1302 to extend to achieve closing buffering of the hinge cup 1 until the hinge cup 1 is completely closed (as shown). Figure 23 shown).
[0067] Therefore, by arranging the first buffer component 5 at the hinge cup 1 and the third buffer component in the hinge arm 2, the hinge structure has both opening buffer and closing buffer functions, thereby slowing down the opening and closing speed of the cabinet door, avoiding cabinet door pinching or collision accidents, and at the same time preventing the cabinet door from violently colliding with other objects and causing damage to the cabinet door and the hinge structure, thereby extending the service life of the product; in addition, by slowing down the opening and closing speed of the cabinet door, it can also avoid the cabinet door from violently colliding with other objects and generating huge noise, thereby creating a quiet environment and improving the user experience.
[0068] Of course, it should be noted that in other embodiments, the third oil cylinder 13 can also be installed in reverse, and the other end of the transmission block 14 can be hinged to the third cylinder body 1301, and the third cylinder body 1301 can be driven to extend relative to the third piston rod 1302 to achieve buffering, which can also achieve the same technical effect, and is not limited here.
[0069] Example 4 See Figures 24-27The hinge structure of this embodiment differs from that of the third embodiment in that the structure of the third buffer component is different. Specifically, the third buffer is a fourth oil cylinder 19, and includes a fourth cylinder body 1901 and a fourth piston rod 1902 movably arranged on the fourth cylinder body 1901. When the fourth piston rod 1902 is driven to be compressed and moved relative to the fourth cylinder body 1901, it can produce a buffering effect; preferably, the fourth driving block is a sliding seat 20, which is slidably arranged in the hinge arm 2; a mounting groove is provided in the sliding seat 20, and the fourth oil cylinder 19 is placed in the mounting groove; wherein, the end of the fourth piston rod 1902 abuts against the inner wall of the mounting groove, and the fourth cylinder body 1901 partially protrudes from the mounting groove and abuts and is limited at the hinge point between the outer rocker arm 3 and the hinge arm 2; wherein, a first protrusion 2001 is provided on the sliding seat 20, and a second protrusion 402 is provided on the end of the inner rocker arm 4 close to the hinge arm 2, and the first protrusion 2001 abuts against the second protrusion 402 to realize a transmission connection.
[0070] Thus, when the hinge cup 1 is in the fully opened state (eg Figures 24-25 As shown), at this time, the fourth piston rod 1902 is in an extended state. When the hinge cup 1 is driven to close, it can drive the inner rocker arm 4 to swing until the hinge cup 1 is closed to a certain angle (such as Figure 26 As shown), the inner rocker arm 4 drives the sliding seat 20 to slide and compress the fourth piston rod 1902 to achieve closing buffering of the hinge cup 1 until the hinge cup 1 is completely closed (as shown). Figure 27 shown).
[0071] Preferably, it also includes a torsion spring 21 provided at the hinge between the outer rocker arm 3 and the hinge arm 2, and the end of the fourth cylinder body 1901 abuts against the torsion spring 21 to achieve limited fixation.
[0072] Of course, it should be noted that in other embodiments, the fourth oil cylinder 19 can also be installed in reverse, and the fourth cylinder body 1901 can be compressed by driving the sliding seat 20 to achieve buffering, which can also achieve the same technical effect and is not limited here.
[0073] In summary, the hinge structure capable of achieving opening buffering provided by the present invention has the following beneficial effects: (1) The hinge structure of the present invention provides a first buffer assembly 5 on the hinge cup 1. When the hinge cup 1 is driven to open to a certain angle, the first buffer in the first buffer assembly 5 can produce a buffering effect on the hinge cup 1, thereby slowing down the opening speed of the cabinet door, thereby avoiding damage to the cabinet door and the hinge structure due to violent impact, and preventing noise generation. In addition, by slowing down the opening speed of the cabinet door, cabinet door pinching accidents can be prevented, reducing safety hazards.
[0074] (2) The hinge structure of the present invention effectively utilizes the external space and avoids the problem of limited internal space by arranging the first buffer assembly 5 outside the groove 101 of the hinge cup 1; in addition, a transmission connection is achieved between one side of the outer rocker arm 3 and the first drive block 501 through the first drive shaft 6. In this way, when the hinge is fully closed, the first drive shaft 6 will be located at the side of the rocker arm assembly, and it does not occupy the depth space of the groove 101. Therefore, there is no need to increase the depth of the groove 101 of the hinge cup 1, so that the thickness of the hinge cup 1 can be made thinner, and then it can be assembled on a door panel with thinner thickness, which is more versatile.
[0075] (3) The hinge structure of the present invention provides a first buffer component 5 and a second buffer component 10 at the hinge cup 1, so that the hinge structure has both opening buffer and closing buffer functions, thereby slowing down the opening and closing speed of the cabinet door, avoiding pinching or collision accidents, and also preventing the cabinet door from violently colliding with other objects, thereby extending the service life of the product; in addition, by slowing down the opening and closing speed of the cabinet door, it can also avoid the cabinet door from violently colliding with other objects and causing huge noise, thereby creating a quiet environment and improving the user experience.
[0076] (4) The hinge structure of the present invention effectively utilizes the external space by arranging the first buffer component 5 and the second buffer component 10 outside the groove 101 of the hinge cup 1, thereby avoiding the problem of limited internal space; in addition, by arranging the first buffer component 5 and the second buffer component 10 on the two outer sides of the groove 101 of the hinge cup 1, the structural layout is more reasonable, the force is more balanced, and it is more compact.
[0077] (5) The hinge structure of the present invention provides a first buffer component 5 at the hinge cup 1 and a third buffer component in the hinge arm 2, so that the hinge structure has both opening buffer and closing buffer functions, thereby slowing down the speed of opening and closing of the cabinet door, avoiding accidents such as cabinet door pinching or collision, and preventing the cabinet door from violently colliding with other objects, thereby extending the service life of the product; in addition, by slowing down the speed of opening and closing of the cabinet door, it can also avoid the cabinet door from violently colliding with other objects and causing damage to the cabinet door and the hinge structure, thereby extending the service life of the product; in addition, by slowing down the speed of opening and closing of the cabinet door, it can also avoid the cabinet door from violently colliding with other objects and generating huge noise, thereby creating a quiet environment and improving the user experience.
