Detailed Description
Fig. 1 is a schematic structural diagram of a slide rail assembly 100 according to an embodiment of the invention, referring to fig. 1. The slide rail assembly 100 may include a slide rail lower rail 101, a slide rail middle rail 103, a slide rail upper rail 104, and a gear 106. The lower rail 101 of the slide rail is provided with a lower rail rack 102. The middle slide rail 103 is located above the lower slide rail 101 and is slidably connected to the lower slide rail 101. The upper rail 104 of the sliding rail is provided with an upper rail rack 105, and the upper rail 104 of the sliding rail is positioned above the middle rail 103 of the sliding rail and can be connected with the middle rail 103 of the sliding rail in a sliding manner. The gear 106 is rotatably arranged on the middle rail 103 of the slide rail, and the gear 106 is respectively meshed with the upper rail rack 105 and the lower rail rack 102. The upper rail 104 is adapted to slide along the middle rail 103 under the action of an external force, and drives the gear 106 to rotate through the upper rail rack 105, so as to drive the middle rail 103 to slide along the lower rail 101 under the rotation of the gear 106.
In the slide rail assembly 100 of the present embodiment, the lower rail rack 102 is in a stationary state (a fixed state). The lower rail rack 102 and the upper rail rack 105 are respectively in meshed connection with the gear 106. Under the action of external force, the upper rail 104 of the slide rail drives the upper rail rack 105 to slide, so that the gear 106 is driven to rotate through the upper rail rack 105, and the middle rail 103 of the slide rail is driven to slide along the lower rail 101 of the slide rail under the rotation of the gear 106. The lower rail rack 102 and the upper rail rack 105 are respectively meshed with the gear 106, so that the movement of the upper rail 104 and the middle rail 103 of the slide rail is more controllable, the friction and the collision between the middle rail 103 of the slide rail and the lower rail 101 and the upper rail 104 of the slide rail are reduced, and the noise is reduced. Moreover, the gear 106 is in surface-to-surface contact with the upper rail 104 and the lower rail 101, respectively, so that the relative positions of the upper rail 104 and the lower rail 101 can be maintained, thereby reducing the left-right shaking amount of the upper rail 104, avoiding the noise caused by collision between the upper rail 104 and surrounding objects, and enabling the upper rail 104 to be pulled out and pushed back more easily under the action of external force.
In one embodiment of the present invention, the length of the lower rail rack 102 is less than the length of the lower rail 101 of the slide rail. The length of the upper rail rack 105 is smaller than the length of the upper rail 104 of the slide rail.
In this embodiment, the upper rail 104 slides along the middle rail 103 under the action of an external force, and the gear 106 is driven to rotate by the upper rail rack 105, so that in the process of driving the middle rail 103 to slide along the lower rail 101 under the rotation of the gear 106, since the lower rail rack 102 is always in a stationary state, the sliding distance of the upper rail 104 relative to the lower rail 101 is greater than the sliding distance of the gear 106 relative to the lower rail 101. Specifically, for example, the sliding distance of the upper slide rail 104 relative to the lower slide rail 101 may be 2 times the sliding distance of the gear 106 relative to the lower slide rail 101, i.e., the sliding distance of the upper slide rail 104 relative to the lower slide rail 101 may be 2 times the sliding distance of the middle slide rail 103 relative to the lower slide rail 101. Therefore, when the slide rail upper rail 104 slides a large distance, the gear 106 does not need to pass through the entire slide rail lower rail 101, so the length of the lower rail rack 102 can be smaller than the length of the slide rail lower rail 101. Likewise, the length of the headrail rack 105 may be less than the length of the sliding track headrail 104. The length of the lower rail rack 102 is smaller than that of the lower rail 101 of the slide rail, and the length of the upper rail rack 105 is smaller than that of the upper rail 104 of the slide rail, so that materials can be saved, and further, the cost is saved.
In one embodiment of the present invention, the lower rail rack 102 may be disposed at one end of the slide rail lower rail 101 facing the pull-out direction. The upper rail rack 105 may be disposed at one end of the slide rail upper rail 104 facing the push-back direction.
In the present embodiment, as shown in fig. 1, the structural schematic diagram of the slide rail assembly 100 in fig. 1 is a structural schematic diagram after the upper rail 104 of the slide rail is pushed back, and the pushed-back state can also be understood as a reset state. Under the condition that the length of the lower rail rack 102 is smaller than that of the lower rail 101 of the slide rail and the length of the upper rail rack 105 is smaller than that of the upper rail 104 of the slide rail, the lower rail rack 102 is arranged at one end of the lower rail 101 of the slide rail, which faces the pulling-out direction, and the upper rail rack 105 is arranged at one end of the upper rail 104 of the slide rail, which faces the pushing-back direction, so that the upper rail 104 of the slide rail can slide for a larger distance. In this embodiment, the sum of the lengths of the lower rail rack 102 and the upper rail rack 105 may be greater than or equal to the length of the lower rail 101 of the slide rail. The gear 106 may be disposed at a position of the middle rail 103 of the slide rail corresponding to a portion where the lower rail rack 102 crosses the upper rail rack 105. The lengths of the lower rack 102 and the upper rack 105 may be the same, and of course, may be different, and this is not specifically limited in the embodiment of the present invention.
In one embodiment of the present invention, the lower rack gear 102, the gear 106, and the upper rack gear 105 are disposed on the same side of the lower track rail 101, the middle track rail 103, and the upper track rail 104. The teeth of the lower rack gear 102 are located on the upper surface of the lower rack gear 102. The individual teeth of the headrail rack 105 are located on the lower surface of the headrail rack 105.
Referring to fig. 1 to 4, in one embodiment of the present invention, the side of the sliding rail head rail 104 on which the head rail rack 105 is disposed has a first protrusion 107. The upper rail rack 105 has a first engaging groove 108 adapted to the first protrusion 107. The side of the lower rail 101 on which the lower rail rack 102 is arranged has a second protrusion 109. The lower rack 102 has a second engaging groove 110 adapted to the second protrusion 109. The first protrusion 107 is located in the first card slot 108. The first protrusion 107 is used to fix the upper rail rack 105 to the upper rail 104. The second protrusion 109 is located in the second card slot 110. The second protrusion 109 is used to fix the lower rack 102 to the lower rail 101.
In one embodiment of the present invention, the first protrusion 107 may be bent in a hook-like structure toward the drawing direction. The second protrusion 109 may be bent in a hook-shaped configuration toward the push-back direction. The first protrusion 107 and the second protrusion 109 of the hook structure can make the upper rail rack 105 and the lower rail rack 102 more stably fixed on the upper rail 104 and the lower rail 101.
In one embodiment of the present invention, one end of the side of the sliding rail upper rail 104 where the upper rail rack 105 is disposed facing the push-back direction has a third catching groove 111. The upper rail rack 105 has a third protrusion 112 matching with the third slot 111. One end of the side surface of the slide rail lower rail 101 on which the lower rail rack 102 is provided, which faces the pull-out direction, is provided with a fourth engaging groove 113. The lower rack 102 has a fourth protrusion 114 matching with the fourth slot 113. The third protrusion 112 is located in the third slot 111. The third protrusion 112 is used to fix the upper rail rack 105 to the upper rail 104. The fourth projection 114 is located in the fourth card slot 113. The fourth protrusion 114 is used to fix the lower rack 102 to the lower rail 101.
In one embodiment of the present invention, the sliding rail assembly 100 may further comprise an upper bead nest member 115 and a lower bead nest member 116 slidably disposed on the upper surface and the lower surface of the sliding rail middle rail 103, respectively. The upper ball nest member 115 has a plurality of upper ball grooves 117 therethrough. The lower ball nest member 116 has a plurality of lower ball grooves 118 therethrough. The upper ball groove 117 is fixed with balls (not shown) rotating therein, which are respectively connected with the middle rail 103 and the upper rail 104. And balls respectively connected with the sliding rail middle rail 103 and the sliding rail lower rail 101 are rotationally fixed in the lower ball groove 118.
In this embodiment, in the process that the upper rail 104 slides along the middle rail 103 under the action of an external force, the balls on the upper ball nest part 115 can be driven to rotate, so that the frictional resistance between the upper rail 104 and the middle rail 103 is reduced, the noise is reduced, and the movement of the upper rail 104 is more stable. The middle rail 103 of the slide rail can drive the balls on the lower ball nest part 116 to rotate in the process of sliding along the lower rail 101 of the slide rail, so that the frictional resistance between the middle rail 103 of the slide rail and the lower rail 101 of the slide rail is reduced, the noise is reduced, and the motion of the middle rail 103 of the slide rail is more stable.
In one embodiment of the present invention, the slide rail assembly 100 may further include a base 119. The base 119 is fixedly coupled to the lower surface of the lower track rail 101 and is used for supporting the track assembly 100.
Referring to fig. 5, the present invention also provides a refrigerator 200 based on the same concept. The refrigerator 200 may include a storage compartment 201, a storage container 202, and two slide rail assemblies 100 according to any of the above embodiments. The two sliding rail assemblies 100 are respectively fixed on two sides of the storage compartment 201. The storage containers 202 are respectively fixedly connected with the upper surfaces of the upper rack bars 105 of the two slide rail assemblies 100.
In the present embodiment, the storage compartment 201 may be a freezing compartment, a refrigerating compartment, or the like. The storage container 202 may be a drawer. Under the action of external force, the upper rail 104 of the sliding rail drives the upper rail rack 105 to slide, so that the gear 106 is driven to rotate through the upper rail rack 105, the middle rail 103 of the sliding rail is driven to slide along the lower rail 101 of the sliding rail under the rotation of the gear 106, and the storage container 202 is pulled out or pushed back from the storage compartment 201. The lower rail rack 102 and the upper rail rack 105 are respectively meshed with the gear 106, so that the movement of the upper rail 104 and the middle rail 103 of the slide rail is more controllable, the friction and the collision between the middle rail 103 of the slide rail and the lower rail 101 and the upper rail 104 of the slide rail are reduced, and the noise is reduced. In addition, the gear 106 is in surface-to-surface contact with the upper rail 104 and the lower rail 101, respectively, so that the relative positions of the upper rail 104 and the lower rail 101 can be maintained, thereby reducing the amount of left and right shaking of the upper rail 104, preventing the upper rail 104 from colliding with the storage compartment 201 to generate noise, and enabling the storage container 202 to be pulled out and pushed back more easily. In addition, in the process of pushing and pulling the storage container 202, the two sliding rail assemblies 100 adopting the gear rack structure can move synchronously, and the problems of distortion, left-right shaking and the like caused by inconsistent movement of the two sliding rail assemblies 100 are avoided.

in the slide rail assembly 100 of the present embodiment, the lower rail rack 102 and the upper rail rack 105 are respectively engaged with the gear 106. Under the action of external force, the upper rail 104 of the slide rail drives the upper rail rack 105 to slide, so that the gear 106 is driven to rotate through the upper rail rack 105, and the middle rail 103 of the slide rail is driven to slide along the lower rail 101 of the slide rail under the rotation of the gear 106. The lower rail rack 102 and the upper rail rack 105 are respectively meshed with the gear 106, so that the movement of the upper rail 104 and the middle rail 103 of the slide rail is more controllable, the friction and the collision between the middle rail 103 of the slide rail and the lower rail 101 and the upper rail 104 of the slide rail are reduced, and the noise is reduced. In addition, the gear 106 is in surface-to-surface contact with the upper slide rail 104 and the lower slide rail 101, respectively, so that the relative positions of the upper slide rail 104 and the lower slide rail 101 can be maintained, thereby reducing the left and right shaking amount of the upper slide rail 104, avoiding the noise caused by the collision between the upper slide rail 104 and surrounding objects, and enabling the upper slide rail 104 to be pulled out and pushed back more easily under the action of external force.
