Detailed Description
The present invention will be described in detail below with reference to specific embodiments shown in the drawings. These embodiments are not intended to limit the invention and structural, methodological, or functional modifications of these embodiments that may be made by one of ordinary skill in the art are included within the scope of the invention.
In the various illustrations of the invention, certain dimensions of structures or portions may be exaggerated relative to other structures or portions for convenience of illustration, and thus serve only to illustrate the basic structure of the inventive subject matter.
As shown in fig. 1, 2 and 3, the present invention provides a rack assembly 100 including a rack 130, a fixing member 110 disposed above the rack 130, and a telescopic mechanism 120 connecting the rack 130 and the fixing member 110.
The rack 130 is movably disposed under the fixing member 110 by a user's operation, and the telescopic mechanism 120 is telescopic and guides the movement direction of the rack 130 during the movement.
The rack 130 has a first position near the fixing member 110, a second position below the first position, and the rack 130 is disposed at a rear side with respect to the first position in the second position. The telescopic mechanism 120 is arranged such that the rack 130 is moved obliquely to the longitudinal direction between the first position and the second position.
The rack 130 may be applied to a refrigerator. When a large article needs to be placed inside the compartment 210 of the refrigerator, the rack 130 is placed at a first position so that a space under the rack 130 is increased, and when the rack 130 is placed at a second position, the rack 130 is used to carry the article. The user can extend and retract the telescopic mechanism 120 by pushing down or lifting up the rack 130, so that the rack 130 can move between the first position and the second position, and the operation is simple and convenient. Since the direction in which the rack 130 moves from the first position to the second position is inclined, the user is required to press the rack 130 downward and the rack 130 can move only by providing the pushing force inclined to the longitudinal direction, the rack 130 does not fall under the action of gravity when being in the first position, and the safety performance is improved.
In one embodiment of the present invention, the telescoping mechanism 120 is a four-bar sliding support mechanism. And in order to improve stability, the number of the telescopic mechanisms 120 is two, and they are respectively connected to both sides of the rack 130. The number of the fixing members 110 is also two, and the fixing members are arranged in one-to-one correspondence with the telescopic mechanisms 120.
The telescopic mechanism 120 includes a slider 121, a first rod 122, a second rod 123, a suspension rod 125, and a long link 124.
The fixing member 110 has a slide rail 111 extending in the front-rear direction. The slider 121 is disposed in cooperation with the slide rail 111, and the slider 121 moves back and forth along the slide rail 111.
The top ends of the first and second levers 122 and 123 are pivotally fixed to the slider 121, and the bottom end of the first lever 122 is located at the rear side of the bottom end of the second lever 123.
The upper and lower ends of the suspension lever 125 are pivotally connected to the bottom end of the first lever 122 and the rack 130, respectively. When the rack 130 is in the first position and the second position, the top end of the hanger bar 125 is located behind the bottom end, i.e., the hanger bar 125 is inclined to the longitudinal direction.
The long link 124 pivotally connects the fixed member 110, the bottom end of the second rod 123, and the suspension rod 125 in this order from the top down, and the connection point of the long link 124 to the fixed member is located at the front side of the slider 121.
The term "pivot connection" as used herein means a connection between two parts by a pivot axis about which at least one of the two parts is rotatable.
Specifically, the long link 124, the first rod 122, and the second rod 123 are inclined in the longitudinal direction, the top end of the long link 124 is forward of the bottom end, the top end of the first rod 122 is forward of the bottom end, and the top end of the second rod 123 is rearward of the bottom end.
When the rack 130 moves from the first position to the second position, the slider 121 moves forward, the long link 124 rotates clockwise around its top end, the first lever 122 rotates clockwise around its top end, the second lever 123 rotates counterclockwise around its top end, the hanger 125 rotates counterclockwise around its top end, and the bottom end of the hanger 125 moves backward and downward.
Specifically, in order to ensure that the movement track of the rack 130 is inclined, to prevent the rack 130 from moving straight in a longitudinal direction, the length of the first rod 122 is smaller than that of the second rod 123, and the length of the second rod 123 is smaller than that of the long link 124; the length of the first lever 122 between its two pivot positions is no greater than the length of the long link 124 between the pivot position connected to the suspension lever 125 and the pivot position connected to the second lever 123; the length of the second lever 123 between its two pivot positions is not less than the length of the suspension lever 125 between the pivot position connected to the first lever 122 and the pivot position connected to the long link 124. And, the connection position of the hanger bar 125 and the long link 124 is above the center of the hanger bar 125 so that the distance of movement of the bottom end of the hanger bar 125 to the rear increases.
The first lever 122 and the second lever 123 are pivotally connected to the fixed member 110 by the same pivot shaft, thereby simplifying the structure of the telescopic mechanism 120 and reducing the cost.
In order to clearly express the positional relationship between the respective rods of the telescopic mechanism 120 in the present invention, an embodiment of the present invention is described by taking a preferred telescopic mechanism 120 as an example.
Specifically, the distance between the pivot positions of both ends of the long link 124 is 105-115mm, and the distance between the pivot position of the bottom end of the long link 124 and the pivot position connected to the second rod 123 is 44-46mm. The distance between the pivoting positions of both ends of the second lever 123 is 63-67mm, and the distance between the pivoting positions of both ends of the first lever 122 is 41-43mm. The distance between the pivoting positions of both ends of the suspension rod 125 is 170-190mm, and the distance between the pivoting position of the tip end of the suspension rod 125 and the pivoting position connected to the long link 124 is 58-62mm. Of course, the length of each component of the telescopic mechanism 120 of the present invention is not limited to the length of each component described above.
As shown in fig. 4, the slide rail 111 is further provided with a limit bump 112. When the rack 130 is at the first position, the sliding block 121 is located at the rear of the limiting protruding block 112, and at this time, the limiting protruding block 112 can limit the sliding block 121 in the front-rear direction, so as to prevent the sliding block 121 from moving forward, thereby ensuring that the telescopic mechanism 120 does not operate when the rack 130 is not subjected to external force, and ensuring that the rack 130 does not fall from the first position.
The limiting bump 112 has elasticity, for example, is made of rubber. When the rack 130 is at the first position, if the user provides pressure to the rack 130 at the rear lower side, the telescopic mechanism 120 stretches, the sliding block 121 can pass over the elastic limit bump 112, the limit bump 112 deforms in the process, and then the rack 130 can move to the second position. When the rack 130 moves to the second position, the slider 121 moves to the front of the limit bump 112, and if the user lifts the rack 130 upward, the slider 121 moves backward, passes over the limit bump 112, and moves until the rack 130 moves to the first position.
The front and rear sides of the limit bump 112 are provided with guide arc surfaces 1121 in the shape of circular arcs. As shown in fig. 5, the rear side of the slider 121 is a guide slope 1211 provided obliquely and an end of the guide slope 1211 remote from the fixing member 110 is rearward of an end near the fixing member 110. By the guide arc surface 1121 of the limit bump 112, when the slider 121 moves forward or backward to more easily pass over the limit bump 112, the resistance of the limit bump 112 to the slider 121 is reduced. The guiding inclined surface 1211 of the slider 121 prevents the slider 121 from being able to pass over the limit bump 112 when moving backward.
The rack 130 has a partition plate 131 and connecting risers 132 extending upward from both sides of the partition plate 131, and the hanger bar 125 is connected to the inner side walls of the connecting risers 132. The partition plate 131 is used for placing articles, the connecting vertical plate 132 is used for being connected with the hanging rods 125, and since the hanging rods 125 are connected with the inner side walls of the connecting vertical plate 132, the telescopic mechanism 120 is located above the partition plate 131, when the rack assembly 100 is installed inside a refrigerator, the telescopic mechanism 120 cannot strike the inner walls of the refrigerator compartment 210 during the movement of the telescopic mechanism 120, so that the safety performance is improved.
As shown in fig. 6, the rack 130 is further provided with a avoidance hole 133 extending longitudinally, the avoidance hole 133 corresponds to the bottom end position of the hanger bar 125, and the width of the avoidance hole 133 in the front-rear direction is greater than the width of the hanger bar 125 in the front-rear direction. The purpose of the avoidance hole 133 is to prevent the rack 130 and the hanger bar 125 from interfering with each other during the movement, so that the distance between the bottom end of the hanger bar 125 and the top of the rack 130 can be set smaller, thereby making the structure more compact.
In an embodiment of the present invention, the hanger bar 125 and the rack 130 are further provided with a structure fixed to each other to prevent the rack 130 from being inclined when the rack 130 is in the first position, ensure the rack 130 to be horizontal, and maintain the rack 130 in the first position by fixing the hanger bar 125 and the rack 130 to each other, not to be dropped by gravity.
As shown in fig. 6, in detail, the side wall of the hanger 125 facing the rack 130 is provided with a positioning block 1251, and the connection riser 132 of the rack 130 is provided with a positioning groove 134 having an upward opening. When the rack 130 is at the first position, the positioning block 1251 is matched with the positioning groove 134, the rack 130 is fixed at the first position through the matching action of the positioning block 1251 and the positioning groove 134, the rack 130 cannot rotate relative to the suspension rod 125, and the rack 130 is maintained at the first position because the rack 130 and the telescopic mechanism 120 cannot move relative to each other.
To facilitate assembly of the positioning groove 134 with the positioning block 1251, the positioning groove 134 extends through the left and right sides of the connecting riser 132 in the left and right direction. The extending direction of the positioning groove 134 is disposed at an angle to the front-rear direction and the top end thereof is located in front of the bottom end, when the rack 130 is in the first position, the inner wall of the positioning groove 134 provides a force to the positioning block 1251 in the longitudinal direction that resists the relative movement of the two, and when the rack 130 is subject to the gravity in the longitudinal direction of itself, the positioning groove 134 is not separated from the positioning block 1251.
As shown in fig. 7, further, the positioning groove 134 includes a lower arc-shaped groove 1342 and a guide channel 1341 located at an upper portion of the arc-shaped groove 1342 and integrated with the arc-shaped groove 1342, the guide channel 1341 has a width smaller than that of the arc-shaped groove 1342, and a rear wall of the guide channel 1341 is located in front of a rear end of the arc-shaped groove 1342 such that a latch 1343 protruding from the arc-shaped groove 1342 is formed at a connection position of the rear wall of the guide channel 1341 and the arc-shaped groove 1342. When the rack 130 is at the first position, the rack 130 is horizontal, and the positioning block 1251 is attached to the inner wall of the arc-shaped groove 1342, and the clamping block 1343 longitudinally limits the positioning block 1251 by abutting the positioning block 1251, so that the rack 130 is prevented from moving.
The positioning block 1251 slides into the arc-shaped groove 1342 from the guide channel 1341, and the front wall and the rear wall of the guide channel 1341 are arc-shaped to facilitate sliding of the positioning block 1251 in the guide channel 1341.
In an embodiment of the present invention, during the process of moving the rack 130 from the second position to the first position, the matching process of the positioning block 1251 and the positioning slot 134 is: when the rack 130 moves to approach the first position, the positioning block 1251 enters the guide passage 1341, and the rear end of the rack 130 is inclined downward during the entering of the guide passage 1341. The rack 130 then continues to move upward, sliding the lower half of the positioning block 1251 into the arcuate slot 1342, and then rotating the rack 130 to the first position while the clamp block 1343 presses the positioning block 1251, with the lower half of the positioning block 1251 in the arcuate slot 1342 and the upper half in the guide channel 1341.
In another embodiment of the present invention, the extension direction of the guide channel 1341 is adapted to the movement track of the positioning block 1251. In the process of moving the rack 130 from the second position to the first position, the matching process of the positioning block 1251 and the positioning groove 134 is as follows: when the rack 130 moves to be close to the first position, the positioning block 1251 enters the guide channel 1341, and the guide channel 1341 is adapted to the movement track of the positioning block 1251, and the guide channel 1341 is obliquely arranged, so that under the cooperation of the positioning groove 134 and the positioning block 1251, the rack 130 can remain hovering even if the user cancels the acting force before the rack 130 moves to the first position.
As shown in fig. 8 and 9, the present invention also provides a refrigerator including a cabinet 200 having a compartment 210, a door 300 to open or close the cabinet 200, and a rack assembly 100 disposed in the compartment 210.
Wherein, the fixing part 110 of the rack 130 is fixedly installed on the inner wall of the compartment 210, and the rack 130 is movably disposed with respect to the case 200.
