Description

Technical Field

[0001] This invention relates to the field of door fittings technology, and more particularly to door opening mechanisms, door components, and storage cabinets. Background Technology

[0002] In related technologies, some high-end refrigerators, such as French-style refrigerators, have a refrigerator compartment at the top and multiple pull-out drawers at the bottom. When the items stored in the pull-out drawers are heavy, or when the user is carrying many items, it is difficult to open the drawers, which affects the user experience. Summary of the Invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a door opening mechanism to make door opening operation more convenient and labor-saving.

[0004] The present invention also proposes a door assembly.

[0005] The present invention also proposes a storage cabinet.

[0006] According to a first aspect of the present invention, the door opening mechanism includes:

[0007] An arc-shaped drive member has a first engagement portion formed along its extension direction, and a force-applying portion is formed at the end of the arc-shaped drive member;

[0008] The door pusher has a first transmission part; the door pusher switches between a hidden position and an extended position.

[0009] A transmission component is disposed between the push door component and the arc-shaped drive component; the transmission component has a second engagement portion that engages with the first engagement portion and a second transmission portion that drives the first transmission portion to move from the hidden position to the extended position according to the movement of the arc-shaped drive component.

[0010] The door opening mechanism of the present invention is simple in structure and convenient in operation. When the door needs to be opened, the user only needs to apply an outward pulling force to the force-applying part of the arc-shaped drive member to gently pull the arc-shaped drive member out. Since the transmission member has a second engagement part that engages with the first engagement part of the arc-shaped drive member and a second transmission part that drives and cooperates with the first transmission part of the push door member, during the outward sliding of the arc-shaped drive member along the edge of the drawer body, the push door member is blocked by the cabinet and applies a forward pushing force to the door, thereby overcoming the door seal suction between the door and the cabinet, allowing the door to pop out from the refrigerator cabinet. That is, in the embodiment of the present invention, the user can easily open the door with the help of the push door member without applying additional pulling force. By setting the arc-shaped drive member, the operation of the arc-shaped drive member is more ergonomically designed, eliminating the need for the user to bend over and allowing the user to open the door in a standing posture, making it more convenient for the user to apply force.

[0011] According to one embodiment of the present invention, the arc-shaped drive member includes an arc-shaped slide plate, and the first engaging portion is disposed on one side of the arc-shaped slide plate.

[0012] According to one embodiment of the present invention, at least part of one long side of the arc-shaped slide plate is bent downward to form a flange, and the first engaging portion is formed at the lower edge of the flange.

[0013] According to one embodiment of the present invention, the force-applying part is a protrusion formed at the first end of the arc-shaped sliding plate, and the angle between the tangential direction of the first end of the arc-shaped sliding plate and the protrusion direction of the force-applying part is less than or equal to 90°.

[0014] According to one embodiment of the present invention, the transmission member includes a pivot portion and a first sector tooth connected to the side wall of the pivot portion, the second engagement portion being a tooth groove formed on the edge of the first sector tooth, and the pivot portion including a rotating shaft or a bushing.

[0015] According to one embodiment of the present invention, the transmission member further includes a second sector tooth connected to the side wall of the pivot portion, the first sector tooth and the second sector tooth being arranged sequentially along the circumference of the pivot portion, and the radius of the first sector tooth being greater than the radius of the second sector tooth; the second transmission part is a tooth groove formed on the edge of the second sector tooth, and the first transmission part is a rack extending along the moving direction of the push door member.

[0016] According to one embodiment of the present invention, the radius of the first sector tooth is greater than or equal to twice the radius of the second sector tooth.

[0017] According to one embodiment of the present invention, it further includes a synchronizing rod and synchronizing wheels fixed at both ends of the synchronizing rod. The synchronizing rod is provided with the transmission member and the push-door member on both sides. The synchronizing rod is provided with the arc-shaped driving member on at least one side. The transmission member forms a third transmission part that drives the synchronizing wheels.

[0018] According to one embodiment of the present invention, the arc-shaped driving member is provided on both sides of the synchronizing rod, and the force-applying parts of the two arc-shaped driving members are connected by a synchronizing plate.

[0019] According to one embodiment of the present invention, a reset member is further included, the reset member being used to drive the push door member to move from the extended position to the concealed position.

[0020] According to a second aspect of the present invention, a door assembly includes a door panel and the aforementioned door opening mechanism, wherein the arc-shaped drive member is slidably mounted on the side edge of the door panel.

[0021] According to one embodiment of the present invention, when the arc-shaped driving members are provided on both sides of the synchronizing rod, the distance between the back faces of the two arc-shaped driving members is equal to the width of the door panel.

[0022] According to a second aspect of the present invention, a storage cabinet includes a cabinet body and at least one drawer, the cabinet body forming a receiving cavity corresponding to the drawer; the drawer includes a drawer body and the aforementioned door assembly, the drawer body is pullable into the receiving cavity, and the door panel is fixed to the side wall of the drawer body facing away from the receiving cavity, the edge of the door panel abutting against the cabinet body.

[0023] The above-described one or more technical solutions in the embodiments of the present invention have at least one of the following technical effects:

[0024] The door opening mechanism of this invention has a simple structure and is easy to operate. When the door needs to be opened, the user only needs to apply an outward pulling force to the force-applying part of the arc-shaped drive member to gently pull it out. Since the transmission member has a second engaging part that engages with the first engaging part of the arc-shaped drive member and a second transmission part that drives the first transmission part of the push-door member, as the arc-shaped drive member slides outward along the edge of the drawer body, the push-door member, blocked by the cabinet, applies a forward pushing force to the door, thereby overcoming the door seal suction between the door and the cabinet, allowing the door to pop out of the refrigerator cabinet. In other words, in this embodiment of the invention, the user can easily open the door with the help of the push-door member without applying additional pulling force. By designing an arc-shaped drive member, the operation of the arc-shaped drive member is more ergonomically designed, allowing the user to open the door while standing without bending over, making it easier for the user to apply force.

[0025] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0039] Combination Figures 1 to 5As shown, an embodiment of the present invention provides a door opening mechanism, which includes an arc-shaped drive member 100, a push door member 300, and a transmission member 200. The arc-shaped drive member 100 has a first engaging portion 102 along its extending direction, and a force-applying portion 103 is formed at its end. The push door member 300 has a first transmission portion, and the push door member 300 switches between a hidden position and an extended position. The transmission member 200 is disposed between the push door member 300 and the arc-shaped drive member 100. The transmission member 200 has a second engaging portion that engages with the first engaging portion 102 and a second transmission portion that drives the push door member 300 from the hidden position to the extended position according to the movement of the arc-shaped drive member 100.

[0040] The following example uses a pull-out drawer in a refrigerator as an example to illustrate the working principle of the pull-out drawer in this embodiment:

[0041] like Figure 1 As shown, the pull-out drawer includes a drawer body and a door panel 800. The door panel 800 is fixed to the front end of the drawer body, and the drawer body and door panel 800 define a receiving cavity with an opening at the top. The edge of the door panel 800 protrudes from the drawer body. It can be understood that the projected area of ​​the drawer body on a vertical plane parallel to the door panel 800 is smaller than the projected area of ​​the door panel 800 on that vertical plane. Part of the projected area of ​​the door panel 800 is located above and to the left and right sides of the projected area of ​​the drawer body. An arc-shaped drive component 100 is slidably mounted on the side edge of the door panel 800. A transmission component 200 and a push-door component 300 are mounted in the installation space defined by the door panel 800 or the installation space jointly defined by the door panel 800 and the drawer body. The arc-shaped drive component 100, transmission component 200, and push-door component 300 are connected to the left and right sides of the drawer body. The drawer body of the pull-out drawer is installed inside the refrigerator cabinet in a pull-out manner. When the pull-out drawer is closed, the edge of the door panel 800 abuts against the cabinet.

[0042] When the straight-pull drawer needs to be opened, the user only needs to apply a pulling force to the force-applying part 103 of the arc-shaped drive member 100 to gently pull the arc-shaped drive member 100 outward. Since the transmission member 200 has a second engagement part that engages with the first engagement part 102 of the arc-shaped drive member 100 and a second transmission part that drives the first transmission part of the push-door member 300, the transmission member 200 moves accordingly as the arc-shaped drive member 100 slides outward along the side edge of the door panel 800, thereby driving the push-door member 300 to extend from the hidden position to the extended position. During this process, the push-door member 300, due to the obstruction of the cabinet, applies a forward pushing force to the drawer body, overcoming the door seal suction between the drawer and the cabinet, thus causing the entire drawer body to pop out of the refrigerator cabinet. Therefore, compared to the user directly pulling the door panel 800 in the transmission drawer, this embodiment, with the assistance of the push-door member 300, makes it much easier for the user to open the drawer door. By setting up an arc-shaped drive component 100, the operation of the arc-shaped drive component 100 by the user is more ergonomically designed, so that the user can open the drawer in a standing position without having to bend over, making it more convenient for the user to apply force.

[0043] like Figure 2 As shown, the arc-shaped drive member 100 includes an arc-shaped slide plate 101, and a first engaging part 102 is disposed on one side of the arc-shaped slide plate 101.

[0044] It is understandable that the first engaging part 102 can be integrally formed on one side of the arc-shaped slide plate 101, or the first engaging part 102 can be set as a structure independent of the arc-shaped slide plate 101, and the two can be connected by fasteners such as bolts and screws, or the edge of the arc-shaped slide plate 101 can be folded down to form the first engaging part 102.

[0045] In this embodiment of the invention, the first engaging portion 102 is formed on the flange formed by folding the edge of the arc-shaped sliding plate 101 downward.

[0046] Please continue reading Figure 2 One of the long sides of the curved sliding plate 101 is at least partially bent downwards to form a flange, and a first engaging portion 102 is formed at the lower edge of the flange. Figure 2 For example, one long side of the curved slide plate 101 is placed on the side edge of the door panel 800, and the rear half of the other long side of the curved slide plate 101 is bent downward to form a flange. That is to say, the projection of the curved slide plate 101 on the horizontal plane is L-shaped. The central angle of the curved plate is not less than 70°.

[0047] In some embodiments, the force-applying part 103 is a protrusion formed at the first end of the curved sliding plate 101. The angle between the tangent direction of the first end of the curved sliding plate 101 and the protrusion direction of the force-applying part 103 is less than or equal to 90°. That is, the force-applying part 103 is inclined from bottom to top toward the second end of the curved sliding plate 101. The advantages of this setting are: on the one hand, it is convenient for the user to apply force. When the user opens the drawer, the movement trajectory of the curved sliding plate 101 is an arc movement toward the user and biased upwards. Compared with the straight movement toward the user or the arc movement trajectory biased downwards, the movement trajectory of the present invention and the inclined setting of the force-applying part 103 can prevent the user's fingers from accidentally slipping off the force-applying part 103 during the process of pulling the curved drive member 100. At the same time, it does not require the user to bend over too low to apply force, and allows the user to conveniently apply the opening force in a more comfortable standing posture. Moreover, since the direction of the force is more in line with ergonomics, the user has a better sense of effort saving. On the other hand, it can prevent the force-applying part 103 from snagging on other items, such as the user's clothing. It should be noted that, by simply using the arc-shaped motion trajectory design of the arc-shaped skateboard 101, even if the force-applying part 103 is set parallel to the door panel 800, the above-mentioned technical effects can still be achieved well.

[0048] like Figure 2 and Figure 4 As shown, the transmission component 200 includes a pivot portion 203 and a first sector tooth 201 connected to the side wall of the pivot portion 203. The second meshing portion is a tooth groove formed on the edge of the first sector tooth 201. The pivot portion 203 includes a rotating shaft or a bushing. The transmission component 200 also includes a second sector tooth 202 connected to the side wall of the pivot portion 203. The first sector tooth 201 and the second sector tooth 202 are arranged sequentially along the circumference of the pivot portion 203, and the radius of the first sector tooth 201 is larger than the radius of the second sector tooth 202. The second transmission portion is a tooth groove formed on the edge of the second sector tooth 202, and the first transmission portion is a rack extending along the moving direction of the push door component 300. Wherein, the radius of the first sector tooth 201 is greater than or equal to twice the radius of the second sector tooth 202. In this case, the user's pulling force can be amplified, allowing the push door component 300 to obtain a greater pushing force, thereby achieving a better force-saving effect.

[0049] Taking the pull-out drawer as an example again, Figure 3 and Figure 4Based on the indicated orientation, the pivot 203 of the transmission component 200 is rotatably mounted on the side wall of the drawer body. When the user applies an outward pulling force to the force-applying part 103 of the arc-shaped drive component 100, the first engaging part 102 of the arc-shaped drive component 100 continuously engages with the tooth groove of the first sector tooth 201, thereby driving the first sector tooth 201 to rotate clockwise. Since the second sector tooth 202 and the first sector tooth 201 are both fixed to the pivot 203, the second sector tooth 202 rotates clockwise synchronously during the clockwise rotation of the first sector tooth 201. During the rotation of the second sector tooth 202, it continuously engages with the rack of the push door component 300, thereby driving the push door component 300 to move to the left. After being blocked by the cabinet, the push door component 300 applies a rightward reaction force to the drawer body, causing the entire pull-out drawer to pop out to the right from the cabinet.

[0050] It should be noted that when the transmission component 200 includes the first sector tooth 201, in addition to using the second sector tooth 202 to drive the push door component 300 from the hidden position to the extended position, other structures can also be used, such as a linkage assembly. This linkage assembly includes a first link and a second link. One end of the first link is fixedly sleeved on the pivot part 203, and the other end of the first link is rotatably connected to one end of the second link. The other end of the second link is rotatably connected to the push door component 300. The side wall of the drawer body has a groove extending along the drawer body's pulling direction, and the push door component 300 is slidably embedded in the groove. Thus, when the user applies an outward pulling force to the force application part 103 of the arc-shaped drive component 100, the first engagement part 102 of the arc-shaped drive component 100 continuously engages with the tooth groove of the first sector tooth 201, thereby driving the first sector tooth 201 to rotate clockwise. Since the end of the first connecting rod is fixedly sleeved on the pivot part 203, when the first sector tooth 201 rotates clockwise, the first connecting rod rotates clockwise around the pivot part 203, and then pushes the push door component 300 to move to the left along the slide groove through the second connecting rod.

[0051] To ensure even force distribution on both sides of the drawer body, and to prevent the drawer body from tilting due to insufficient reaction force from the sliding door mechanism 300 when force is applied to only one side, such as... Figure 1 As shown, the door opening mechanism also includes a synchronizing rod 400 and synchronizing pulleys 500 fixed to both ends of the synchronizing rod 400. Both sides of the synchronizing rod 400 are provided with a transmission component 200 and a door-pushing component 300. At least one side of the synchronizing rod 400 is provided with an arc-shaped driving component 100. The transmission component 200 forms a third transmission part that drives the synchronizing pulleys 500. The synchronizing pulleys 500 may be, but are not limited to, a synchronizing gear or a synchronizing belt pulley.

[0052] When the synchronizing pulley 500 is a synchronizing gear, the third transmission part is a third meshing part formed on the transmission member 200, and the third meshing part can be integrated with the second meshing part. For example, as Figure 2As shown, when the transmission component 200 includes the first sector tooth 201, the second and third meshing portions are both tooth grooves on the edge of the first sector tooth 201. That is, the first sector tooth 201 simultaneously meshes with the arc-shaped drive component 100 and the synchronous gear. Therefore, when the user applies an outward pulling force to the force-applying portion 103 of the arc-shaped drive component 100, the first meshing portion 102 of the arc-shaped drive component 100 continuously meshes with the tooth groove of the first sector tooth 201, thereby driving the first sector tooth 201 to rotate clockwise. Simultaneously, the first sector tooth 201 continuously meshes with the synchronous gear, thereby driving the synchronous gear to rotate counterclockwise. Due to the presence of the synchronizing rod 400, the two synchronous gears always remain synchronized and rotate in the same direction, thus ensuring that the two push-door components 300 maintain synchronized movement.

[0053] When the synchronous pulley 500 is a synchronous belt pulley, the third transmission part includes a transmission pulley and a synchronous belt. When the transmission member 200 includes a first sector tooth 201, the transmission pulley is fixedly sleeved on the pivot part 203, and the transmission pulley and the synchronous belt pulley are connected by a synchronous belt. Thus, when the user applies an outward pulling force to the force-applying part 103 of the arc-shaped drive member 100, the first meshing part 102 of the arc-shaped drive member 100 continuously meshes with the tooth groove of the first sector tooth 201, thereby driving the first sector tooth 201 to rotate clockwise, and the transmission pulley rotates clockwise accordingly, thereby driving the synchronous belt pulley to rotate clockwise. Due to the presence of the synchronous rod 400, the two synchronous pulleys always remain synchronized and rotate in the same direction, thereby making the two push door members 300 maintain synchronized movement.

[0054] like Figure 1 and Figure 5 As shown, both sides of the synchronizing rod 400 are provided with arc-shaped driving components 100, and the force-applying parts 103 of the two arc-shaped driving components 100 are connected by the synchronizing plate 600. The advantage of this arrangement is that it can ensure the force balance of the two transmission components 200, and it is also convenient for the user to pull the two arc-shaped driving components 100 at the same time.

[0055] In addition, the door opening mechanism also includes a reset component, which drives the push door component 300 from the extended position to the retracted position. To achieve automatic reset of the push door component 300, the reset component can adopt various structural forms, such as:

[0056] Form 1, such as Figure 2As shown, the reset component includes a torsion spring 700, which is sleeved on the pivot portion 203, with both ends of the torsion spring 700 abutting against the first sector tooth 201 and the side wall of the drawer body, respectively. Both the first sector tooth 201 and the side wall of the drawer body can be provided with protrusions for abutting against the torsion spring 700. Thus, during the clockwise rotation of the first sector tooth 201 driven by the arc-shaped drive component 100, the torsion spring 700 undergoes torsional deformation. When the user releases the arc-shaped drive component 100, the first sector tooth 201 rotates counterclockwise under the restoring force of the torsion spring 700, thereby causing the arc-shaped drive component 100 to slide inwards towards the drawer body. Simultaneously, the push-door component moves from the extended position to the concealed position under the drive of the transmission component 200, allowing the user to simply push the pull-out drawer back into the cabinet after retrieving items from it.

[0057] Form 2: The reset component includes a compression spring. The push door component 300 has a mounting cavity, which is open on the side facing the drawer body. The end face of the push door component 300 away from the cabinet body has a guide rod extending into the mounting cavity, which extends along the pulling direction of the push door component 300. The side wall of the drawer body has a mounting protrusion extending into the mounting cavity, which is positioned opposite to the guide rod. The compression spring is sleeved on the guide rod, with one end abutting against the end face of the push door component 300 away from the cabinet body and the other end abutting against the mounting protrusion. Thus, as the arc-shaped drive component 100 drives the push door component 300 to move to the left via the transmission component 200, that is, as the push door component 300 moves from the concealed position to the extended position, the end face of the push door component 300 away from the cabinet door continuously approaches the mounting protrusion, and the compression spring located between the two is continuously compressed. When the user releases the arc-shaped drive component 100, the push door component 300 is no longer driven by the arc-shaped drive component 100 through the transmission component 200. At this time, the push door component 300 moves to the right under the drive of the spring return force until it moves from the extended position to the hidden position. Thus, after the user takes the items out of the straight drawer, he can directly push the straight drawer into the cabinet.

[0058] Method 3: The reset component includes a first magnetic component and a second magnetic component. The push door component 300 has a mounting cavity, which is open on the side facing the drawer body. The side wall of the drawer body has a mounting protrusion that extends into the mounting cavity. The first magnetic component is fixed to the end face of the push door component 300 away from the cabinet body, and the second magnetic component is fixed to the side of the mounting protrusion facing the first magnetic component. The first and second magnetic components repel each other. Therefore, as the arc-shaped drive component 100 drives the push door component 300 to move to the left through the transmission component 200, that is, as the push door component 300 moves from the hidden position to the extended position, the end face of the push door component 300 away from the cabinet door continuously approaches the mounting protrusion, and the repulsive force exerted by the second magnetic component on the first magnetic component continuously increases. When the user releases the arc-shaped drive component 100, the sliding door component 300 is no longer driven by the arc-shaped drive component 100 through the transmission component 200. At this time, driven by the repulsive force exerted by the second magnetic component, the sliding door component 300 moves to the right until it moves from the extended position to the retracted position. Thus, after the user takes items from the pull-out drawer, they can simply push the drawer back into the cabinet. The first and second magnetic components are parts capable of responding to a magnetic field; for example, the first and second magnetic components can be, but are not limited to, magnets.

[0059] Of course, the reset component can also adopt a combination of the above methods or other structural forms. In addition, in order to reset the push door component 300, the user can also directly apply an inward pushing force to the arc-shaped drive component 100, which drives the first sector tooth 201 and the second sector tooth 202 to rotate counterclockwise. The second sector tooth 202 can then drive the push door component 300 to move to the right from the extended position to the hidden position.

[0060] It should be noted that, in addition to the structural forms described above, the transmission component 200 and the push-door component 300 can also adopt other structural forms such as cams and connecting rods. For example, the transmission component 200 includes a cam and a driven rod, with the driven rod slidably disposed below the cam; the circumferential surface of the cam includes an arc segment centered on the cam's rotation center and a curved surface segment with varying radius vectors; the arc segment of the cam forms a second meshing part, and the top end of the driven rod abuts against the curved surface segment of the cam; the side wall of the driven rod forms a toothed groove extending along its length; the push-door component includes a driven gear and a push rack, with the push rack disposed below the driven rod, and the driven gear meshing with the toothed groove of the driven rod and the push rack respectively. Therefore, when the arc-shaped drive component 100 drives the cam to rotate clockwise, the driven rod moves downward under the guidance of the arc segment of the cam, thereby driving the driven gear meshing with it to rotate clockwise. The driven gear will then drive the push rack meshing with it to move to the left, that is, from the hidden position to the extended position.

[0061] like Figure 1 and Figure 5As shown, this embodiment of the invention also provides a door assembly, which includes a door panel 800 and the aforementioned door opening mechanism, with an arc-shaped drive member 100 slidably mounted on the side edge of the door panel 800.

[0062] To improve aesthetics and achieve a fully continuous effect, with arc-shaped drive components 100 on both sides of the synchronizing rod 400, the distance between the back faces of the two arc-shaped drive components 100 is equal to the width of the door panel 800.

[0063] In addition, this embodiment of the invention also provides a storage cabinet, which includes a cabinet body and at least one drawer. The cabinet body forms a receiving cavity corresponding to the drawer. The drawer includes a drawer body and the aforementioned door assembly. The drawer body is pullable and disposed in the receiving cavity. A door panel 800 is fixed to the side wall of the drawer body facing away from the receiving cavity, and the edge of the door panel 800 abuts against the cabinet body.

[0064] The door assembly and locker in the embodiments of the present invention make the opening operation more convenient and labor-saving by adopting the above-mentioned door opening mechanism.
