[0047] The present invention will now be described in detail with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional modifications made by those skilled in the art based on these embodiments are included within the scope of protection of the present invention.

[0048] It should be noted that the term "comprising" or any other variation thereof is intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus. Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0049] This invention provides a door assist component, such as Figure 1 and Figure 2 As shown, this is applied to the field of door opening and closing assistance. The door body 21 is used to open or close the cabinet 2, and the assistance component is used to assist in opening or closing the cabinet 2. The cabinet 2 can be a cabinet or a refrigeration device such as a refrigerator.

[0050] In an embodiment of the present invention, a refrigeration device is used as an example for explanation. A door assist component is installed in the refrigeration device to assist in opening or closing the door 21 of the refrigeration device.

[0051] like Figure 3 As shown, the door assist assembly includes a first push rod 1 and a first assist mechanism 3. The first assist mechanism 3 assists the first push rod 1 to open the door 21. The first push rod 1 is installed inside the housing 2. The first push rod 1 includes a first mating part 1a and a first end 11. When the door is closed, the first end 11 is close to the first wall surface 21a.

[0052] The first assist mechanism 3 is installed inside the housing 2. Specifically, the first assist mechanism 3 is inside the housing 2 and partially extends from the front side of the housing 2. The first assist mechanism 3 is movably arranged inside the housing 2 to facilitate pressing, stepping on, and pulling the first assist mechanism 3 so that the first assist mechanism 3 can move in a first direction. The first assist mechanism 3 includes a second mating part 31, which is close to the first mating part 1a when the door is closed.

[0053] The first assist mechanism 3 moves along a first direction, the second mating part 31 acts on the first mating part 1a, and the first end 11 moves toward the first wall surface 21a. This first direction indicates that the first assist mechanism 3 moves vertically or along the front-back direction of the housing 2. When the first assist mechanism 3 moves vertically, it presses against the first push rod 1, causing the first push rod 1 to move in the front-back direction of the housing 2. When the first assist mechanism 3 moves along the front-back direction of the housing 2, it pulls against the first push rod 1, causing the first push rod 1 to move in the front-back direction of the housing 2. Furthermore, in other embodiments, the first direction may also include other directions to cause the first push rod 1 to move toward the first wall surface 21a.

[0054] In one embodiment, the second mating part 31 protrudes from the surface of the first assist mechanism 3 and abuts against the surface of the first push rod 1 and the first mating part 1a. The second mating part 31 acts on the first mating part 1a of the first push rod 1 to drive the first end 11 of the first push rod 1 to move toward the first wall surface 21a of the door body 21. The first end 11 drives the door body 21 to rotate and open around the hinge assembly.

[0055] In one embodiment, the first end portion 11 protrudes from the first push rod 1 in the direction of the door body 21. In another embodiment, the first end portion 11 is part of the end portion of the first push rod 1 and has the same dimensions as the first push rod 1.

[0056] The first end 11 moves out of the box 2 under the force applied by the first assist mechanism 3. When the first end 11 extends out of the box 2, it abuts against the door 21 and pushes the door 21 to open.

[0057] Thus, the first assist mechanism 3 can cause the first push rod 1 to move, so that the first end 11 can push the door 21 open. In addition, when the first assist mechanism 3 is set at the bottom of the box 2, specifically, the first assist mechanism 3 is set at the bottom of the box 2 and extends partly towards the front of the box 2 and extends partly into the box 2 to abut against the first push rod 1, so that when the hands are occupied, the first assist mechanism 3 can be pressed or pulled by the foot to make the first push rod 1 open the door, which greatly improves the convenience of opening the door; at the same time, it also makes it easy for children and people with weak strength to open.

[0058] In one embodiment, the first end 11 is located inside the housing 2 and does not contact the door 21 in the initial position. In another embodiment, the first end 11 abuts against the door 21 in the initial position. It should be noted that the force of the first end 11 abutting against the door 21 in the initial position is less than the force required to open the door 21.

[0059] The first assist mechanism 3 moves inside the bottom of the housing 2. In one embodiment, the first assist mechanism 3 is limited to vertical movement. In another embodiment, the first assist mechanism 3 is limited to forward and backward movement. The vertical direction refers to movement along the height of the housing 2, and the forward and backward direction refers to movement along the front and rear of the housing 2.

[0060] In one embodiment of the present invention, when the first assist mechanism 3 moves, it drives the first push rod 1 to move or rotate through the second mating part 31 so that the first end 11 acts on the door body 21.

[0061] In one embodiment of the present invention, an elastic element 12 is provided on the first push rod 1, which is elastically connected to the housing 2. When the first push rod 1 is displaced or rotated, the elastic element 12 generates a force that restores the first push rod 1 to its initial state. Thus, the elastic element 12 assists the first push rod 1 in returning to its initial position after movement, allowing the first push rod 1 to be reset in a timely manner, facilitating repeated use.

[0062] In one embodiment, such as Figure 4 or Figure 5 As shown, when the first assist mechanism 3 moves down or rises up, it forces the first push rod 1 to move toward the door body 21, and the first end 11 moves toward the door body 21 simultaneously.

[0063] In one embodiment, such as Figure 6 As shown, when the first assist mechanism 3 moves toward the door body 21, it simultaneously pulls the first push rod 1 toward the door body 21, and the first end 11 moves toward the door body 21 in sync.

[0064] It should be noted that in the above two embodiments, the elastic element 12 is a spring, one end of which is connected to the first push rod 1 and the other end is fixedly connected to the box body 2. When the first push rod 1 moves toward the door, it compresses the spring. When the first assist mechanism 3 stops applying force, the first push rod 1 returns to its initial position under the action of the spring.

[0065] In one embodiment, such as Figure 7 As shown, when the first assist mechanism 3 moves away from the door body 21, it pushes the second mating part 31 of the first push rod 1 to move away from the door body 21 in a synchronous manner. The first push rod 1 has a central positioning shaft. The first push rod 1 rotates along the central positioning shaft so that the first end 11 moves towards the door body 21.

[0066] It should be noted that in this embodiment, the elastic element 12 is an elastic torsion spring. The torsion spring rotates and fixes the central positioning shaft of the first push rod 1 inside the housing 2. When the first push rod 1 rotates, the torsion spring contracts. When the first assist mechanism 3 stops applying force, the first push rod 1 returns to its initial position under the action of the torsion spring.

[0067] Thus, by displacing or rotating the first push rod 1, the first end 11 can be extended out of the box 2, thereby pushing the door 21 open.

[0068] In one embodiment of the present invention, a first pressing strip 32 is provided on the second mating part 31, and a second pressing strip 13 is provided on the side of the first push rod 1 facing the second mating part 31.

[0069] The second pressing strip 13 has an arc-shaped surface or inclined surface that abuts against the first pressing strip 32. The first pressing strip 32 acts on the arc-shaped surface or inclined surface of the second pressing strip 13 to drive the first push rod 1 to move.

[0070] In one embodiment, such as Figure 4 As shown, the arc-shaped surface or inclined surface of the second pressing strip 13 is formed on the bottom surface of the second pressing strip 13 such that the arc-shaped surface or inclined surface faces downward.

[0071] Thus, the second mating part 31 is located below the second pressing strip 13 of the first push rod 1. When the first assist mechanism 3 is lifted upward, the first pressing strip 32 abuts against the second pressing strip 13 and applies force along the arc surface or inclined surface. The component of the force on the arc surface or inclined surface causes the first push rod 1 to move toward the door body 21.

[0072] In one embodiment, such as Figure 5 As shown, the arc-shaped surface or inclined surface of the second pressing strip 13 is formed on the top surface of the second pressing strip 13 such that the arc-shaped surface or inclined surface faces upward.

[0073] Thus, the second mating part 31 is located above the second pressing strip 13 of the first push rod 1. When the first assist mechanism 3 presses down, the first pressing strip 32 abuts against the second pressing strip 13 and applies force along the arc surface or inclined surface. The component of the force on the arc surface or inclined surface causes the first push rod 1 to move toward the door body 21.

[0074] In one embodiment of the present invention, the first pressing strip 32 has an arc-shaped surface or a slope that abuts against the second pressing strip 13. This reduces wear when the first pressing strip 32 and the second pressing strip 13 abut against each other, and the compression between the arc-shaped surface or the slope makes the movement of the first push rod 1 more gradual.

[0075] The curved or inclined surfaces of the first pressing strip 32 and the second pressing strip 13 are made of flexible materials such as elastic materials.

[0076] In one embodiment of the present invention, such as Figure 8 As shown, the first assist mechanism 3 includes a first outer shell plate 33 and a first inner plate 34. The first outer shell plate 33 is installed inside the bottom of the housing 2. A first receiving cavity 331 is provided inside the first outer shell plate 33. The first inner plate 34 is movably installed in the first receiving cavity 331.

[0077] The first inner plate 34 is limited to move along the opening direction of the first accommodating cavity 331. The first inner plate 34 extends within the first outer shell 33, thus having a larger contact area, which facilitates the application of force to the first assist mechanism 3 by personnel. In addition, in practical applications, the first outer shell 33 can be installed at the bottom of the housing 2, and the first inner plate 34 extends out of the housing 2 when not in use. In this way, the first inner plate 34 can be hidden and stored, and the first outer shell 33 can also be placed inside the housing 2, thereby reducing the occupied area.

[0078] One way to achieve the extension and retraction of the first inner plate 34 within the first accommodating cavity 331 is to provide limiting grooves on both sides of the first accommodating cavity 331, with the protruding structures on both sides of the first inner plate 34 embedded in the limiting grooves. Alternatively, the first inner plate 34 can be prevented from detaching from the first accommodating cavity 331 by setting the size of the opening of the first accommodating cavity 331 to be smaller than the size of the internal space of the first accommodating cavity 331.

[0079] In one embodiment, the first accommodating cavity 331 provided within the first outer shell plate 33 can be a spatial structure that is closed on five sides and open on one side. The first inner plate 34 extends into the first outer shell plate 33 through the opening.

[0080] In another embodiment, the first accommodating cavity 331 may be a structure formed by recessing from the top or bottom surface of the first outer shell plate 33, and the first inner plate 34 is stacked on the top or bottom surface of the first outer shell plate 33.

[0081] In addition, in other embodiments, the first outer shell 33 and the first inner shell 34 are not limited to plate-shaped structures, such as retractable strip structures.

[0082] In one embodiment of the present invention, such as Figure 9 As shown, the housing 2 is provided with a first space slot 22 for installing the first push rod 1. The first space slot 22 has a slot 221 for the first end 11 to extend out, wherein the first end 11 moves out of the slot 221 to abut against the door 21.

[0083] The elastic element 12 is fixedly connected to the inner wall of the first space groove 22.

[0084] The first spatial groove 22 is adapted to the outer contour of the first push rod 1, and the size of the first spatial groove 22 is larger than the size of the first push rod 1 so that the first push rod 1 can move within the first spatial groove 22.

[0085] When the first push rod 1 moves in a straight line, the elastic element 12 is fixedly connected to the front or rear wall of the first space groove 22 in the direction of movement.

[0086] When the first push rod 1 rotates, the elastic element 12 is installed on the top or bottom wall of the first space groove 22.

[0087] The housing 2 is provided with a second space slot 23 for accommodating the second mating part 31, and the second space slot 23 is connected to the first space slot 22.

[0088] The second mating part 31 is located in the second space groove 23. The size of the second space groove 23 is larger than the size of the second mating part 31, so that the first assist mechanism 3 can drive the second mating part 31 to move within the second space groove 23.

[0089] The second space groove 23 can be larger in the height direction than the size of the second mating part 31, so that the second mating part 31 can move up and down. This facilitates the movement of the second mating part 31 by pressing it.

[0090] The second space groove 23 can be larger than the size of the second mating part 31 in the depth direction of the front and rear of the housing 2, so that the second mating part 31 can move back and forth. This facilitates pulling or pushing the second mating part 31.

[0091] In one embodiment, a first spatial groove 22 is formed in the bottom of the housing 2, and a second spatial groove 23 is recessed from the bottom of the housing 2 and communicates with the outside. A first assist mechanism 3 is located at the bottom of the housing 2, and a second mating part 31 extends from the bottom into the second spatial groove 23. A first push rod 1 is accommodated in the first spatial groove 22. The first assist mechanism 3 can be connected to the housing 2 through other components, such as a spring connection to the bottom of the housing 2, a telescopic rod connection, or a limiting member connection. Specifically, the first assist mechanism 3 has a protruding structure, and the bottom of the housing 2 has a recessed strip-shaped groove structure. The protruding structure is embedded in the strip-shaped groove structure, limiting the first assist mechanism 3 to move along the front-back direction or up-down direction of the housing 2. Further details are omitted here.

[0092] In one embodiment, a first spatial groove 22 is formed in the bottom of the housing 2, and a second spatial groove 23 is recessed from the bottom of the front side of the housing 2. Specifically, it can be formed below the first spatial groove 22. The first spatial groove 22 has an L-shaped structure to accommodate the first assist mechanism 3 and its second mating part 31. The connection structure between the first assist mechanism 3 and the first spatial groove 22 is described in the example above and will not be repeated here.

[0093] In one embodiment of the present invention, such as Figure 1 , Figure 2 and Figure 10 As shown, the door assist assembly also includes a second push rod 4, a gear set 5, and a second assist mechanism 6. The second assist mechanism 6 drives the second push rod 4 to move, the second push rod 4 drives the gear set 5 to rotate, and the gear set 5 drives the hinge assembly on the door 21 to operate and close the door 21.

[0094] It should be noted that when the first push rod 1 opens the door 21, the hinge assembly on the door 21 operates, thereby driving the second push rod 4 to act on the second assist mechanism 6. Conversely, the second assist mechanism 6 acts in the opposite direction on the second push rod 4, and the second push rod 4 closes the door 21 again through the rotation of the gear set 5.

[0095] The second push rod 4 is installed inside the housing 2. The second push rod 4 includes a third mating part 4a and a rack 41 disposed at the end.

[0096] The gear set 5 is used to mesh with the hinge set on the door body 21 and the rack 41.

[0097] The second assist mechanism 6 is installed inside or at the bottom of the housing 2. Specifically, when the second assist mechanism 6 is installed in the housing 2, part of it extends out from inside the housing 2 and is movable within the housing 2. When the second assist mechanism 6 is installed at the bottom of the housing 2, part of it extends forward towards the front of the housing 2, and part of it extends into the housing 2 to abut and cooperate with the second push rod 4. It includes a fourth mating part 61, which, in the open state, is close to the third mating part 4a.

[0098] The second assist mechanism 6 moves along a second direction and acts on the third mating part 4a, with the rack 41 moving toward the gear set 5. This second direction refers to the direction in which the second assist mechanism 6 moves vertically or laterally along both sides of the housing 2. When the second assist mechanism 6 moves vertically, it compresses the second push rod 4, causing it to move toward the gear set 5. When the second assist mechanism 6 moves laterally along both sides of the housing 2, it pushes the second push rod 4 toward the gear set 5. Furthermore, in other embodiments, the second direction may include other directions to cause the second push rod 4 to move toward the gear set 5.

[0099] The fourth mating part 61 of the second assist mechanism 6 protrudes from the surface of the second assist mechanism 6 and abuts against the second push rod 4. The fourth mating part 61 acts on the third mating part 4a of the second push rod 4 to drive the second push rod 4 to move toward the gear set 5.

[0100] Thus, based on the force applied by the second assist mechanism 6 to the second push rod 4, the second push rod 4 closes the door 21 through the gear set 5. When both hands are occupied, the second assist mechanism 6 can be used to close the door by foot, which greatly improves the convenience of closing the door.

[0101] The gear set 5 includes at least one gear. When the second push rod 4 moves laterally, the rack 41 drives the gear set 5 to rotate through meshing with it. The gear set 5 then drives the door body 21 to rotate to open or close the door through meshing with the hinge set.

[0102] In one embodiment of the present invention, when the second assist mechanism 6 moves, it drives the second push rod 4 to move through the fourth mating part 61 to drive the gear set 5 to rotate and act on the hinge set on the door body 21.

[0103] In one embodiment, the second assist mechanism 6 is limited to vertical movement, and the fourth mating part 61 presses and drives the second push rod 4 to move laterally so that the gear set 5 rotates. Figure 11 As shown, the fourth mating part 61 presses upward and drives the second push rod 4 to move laterally. (As indicated...) Figure 12 As shown, the fourth mating part 61 presses downward and drives the second push rod 4 to move laterally.

[0104] In one embodiment, such as Figure 13 As shown, the second assist mechanism 6 is limited to lateral movement, and the fourth mating part 61 pushes and drives the second push rod 4 to lateral displacement so that the gear set 5 rotates.

[0105] In the above embodiment, during the closing process of the door 21, the gear set 5 rotates in the opposite direction to drive the second push rod 4 to return to its original position. During the return process of the second push rod 4, it squeezes or pushes the fourth mating part 61 to make the second assist mechanism 6 return to its original position.

[0106] In one embodiment of the present invention, the end of the second push rod 4 is formed with an arc-shaped surface or inclined surface that abuts against the fourth mating part 61.

[0107] Thus, when the fourth mating part 61 moves up and down, it presses against the arc-shaped surface or the inclined surface, thereby generating a force component on the arc-shaped surface or the inclined surface that pushes the second push rod 4 to move laterally, thereby driving the second push rod 4 to move laterally and causing the gear set 5 to rotate.

[0108] In one embodiment of the present invention, the end of the fourth mating part 61 is formed with an arc-shaped surface or inclined surface that abuts against the second push rod 4.

[0109] Thus, both the fourth mating part 61 and the second push rod 4 are provided with arc-shaped surfaces or bevels to reduce wear.

[0110] The fourth mating part 61 and the arc-shaped or inclined surface of the second push rod 4 are made of flexible material such as elastic material.

[0111] In one embodiment of the present invention, such as Figure 14 As shown, the second assist mechanism 6 includes a second outer shell plate 62 and a second inner plate 63. The second outer shell plate 62 is installed at the bottom of the housing 2, and a second receiving cavity 621 is provided inside the second outer shell plate 62. The second inner plate 63 is movably installed in the second receiving cavity 621.

[0112] The second inner plate 63 is limited to move along the opening direction of the second accommodating cavity 621. The second inner plate 63 extends within the second outer shell 62, thus having a larger contact area, facilitating the application of force to the second assist mechanism 6. Furthermore, in practical applications, the second outer shell 62 can be installed inside the housing 2, and the second inner plate 63 extends out of the housing 2 when not in use. This allows the second inner plate 63 to be hidden and stored away, and the second outer shell 62 to remain within the housing 2, thereby reducing the area occupied.

[0113] The second inner plate 63 can be extended and retracted within the second accommodating cavity 621 by setting limiting grooves on both sides of the second accommodating cavity 621, with the protruding structures on both sides of the second inner plate 63 embedded in the limiting grooves. Alternatively, the second inner plate 63 can be prevented from detaching from the second accommodating cavity 621 by setting the size of the opening of the second accommodating cavity 621 to be smaller than the size of the internal space of the second accommodating cavity 621.

[0114] In one embodiment, the second accommodating cavity 621 provided within the second outer shell plate 62 can be a spatial structure that is closed on five sides and open on one side. The second inner plate 63 extends into the second outer shell plate 62 through the opening.

[0115] In another embodiment, the second accommodating cavity 621 may be a structure formed by recessing from the top or bottom surface of the second outer shell plate 62, and the second inner plate 63 is stacked on the top or bottom surface of the second outer shell plate 62.

[0116] Furthermore, in other embodiments, the second outer shell 62 and the second inner shell 63 are not limited to plate-like structures; for example, a retractable strip structure may also be used.

[0117] In one embodiment of the present invention, such as Figure 15 and Figure 16As shown, the housing 2 is provided with a third space slot 24 for accommodating the fourth mating part 61, a fourth space slot 25 for installing the second push rod 4 and a fifth space slot 26 for installing and accommodating the gear set 5.

[0118] The third space slot 24 is connected to the fourth space slot 25, and the fourth space slot 25 is connected to the fifth space slot 26.

[0119] The third space groove 24 is connected to the fourth space groove 25, allowing the fourth mating part 61 to abut against the second push rod 4. In one embodiment, one end of the second push rod 4 extends into the third space groove 24 and abuts against the fourth mating part 61.

[0120] The fourth mating part 61 moves laterally or vertically within the third space slot 24, causing the second push rod 4 to move laterally within the fourth space slot 25.

[0121] The fourth space slot 25 is connected to the fifth space slot 26 so that the gear set 5 can mesh with the rack 41.

[0122] The second push rod 4 moves laterally in the fourth space slot 25, and drives the gear set 5 to rotate in the fifth space slot 26 through the rack 41. The rotation of the gear set 5 drives the hinge assembly to operate.

[0123] In one embodiment of the present invention, a refrigeration device is provided, the refrigeration device including a housing 2 and a door 21 for opening or closing the housing 2.

[0124] The refrigeration equipment also includes the door assist component as described in any of the above embodiments.

[0125] In one embodiment, the door assist assembly is applied to opening or closing one door 21 of the housing 2. Therefore, two door assist assemblies are provided at the bottom of the housing 2, corresponding to the two doors 21 respectively. Alternatively, only one door assist assembly is provided when there is only one door 21.

[0126] Taking a refrigeration device comprising a left door 21 and a right door 21 as an example, two sets of door-assisting components are provided, one set located below the left door 21 and the other set located below the right door 21. The door-assisting component below the left door 21 is used to open the left door 21; the door-assisting component below the right door 21 is used to open the right door 21. Alternatively, the door-assisting component below the left door 21 can be used to open the right door 21, and the door-assisting component below the right door 21 can be used to open the left door 21.

[0127] In summary, this invention designs a door-assisting component that can be installed inside a cabinet 2 with a door 21. Specifically, it can be installed at the bottom of the cabinet 2, allowing the door 21 to be opened by stepping or pushing; or it can be installed at the top of the cabinet 2, allowing the door 21 to be opened by manually pressing, pushing, or pulling. In the refrigeration equipment provided by this invention, to solve the problem of inconvenience in opening the door due to occupied hands, the door-assisting component is installed at the bottom of the cabinet 2. In other cabinet door embodiments, it can be installed in other positions corresponding to the door 21. The door-assisting component is designed with a first push rod 1 and a first assist mechanism 3, so that the first push rod 1 is moved or rotated by applying force to the first assist mechanism 3 to open the door 21; the door-assisting component also includes a second push rod 4, a gear set 5, and a second assist mechanism 6, so that the second push rod 4 is moved by applying force to the second assist mechanism 6, and then the door 21 is closed by the action of the hinge group through the rotation of the gear set 5. Simultaneously, when the first push rod 1 opens the door 21, the rotation of the hinge assembly causes the second push rod 4 to move in the opposite direction, thereby driving the second assist mechanism 6 to switch to a certain state. Changing this state, such as by pressing or pushing the second assist mechanism 6, causes the second push rod 4 to move away from the second assist mechanism 6, thus closing the door. Ultimately, the door assist assembly of this invention allows for assisted opening and closing of doors without the use of both hands, without requiring electricity or incurring significant costs, greatly improving the convenience of opening and closing doors.
